In patients with cancer, however, recurrent VTE after DOAC treatment may be more common than in noncancer patients. To evaluate our hypothesis that the anticoagulation effect of edoxaban is lower in VTE patients with cancer than in noncancer patients.
Methods This study was a prospective, multicenter, observational study including patients treated with edoxaban for VTE in Japan. The primary outcome was the difference in the prothrombin time (PT), activated partial thromboplastin time (APTT), and D-dimer level at 5 h after initial edoxaban administration between the cancer and noncancer groups. An additional outcome was the longitudinal change in PT and APTT from 5 h to overnight after edoxaban administration. The incidence of adverse events was further investigated.
Results PT and APTT at 5 h after initial edoxaban administration were not significantly different between the cancer (n = 84) and noncancer groups (n = 138) (e.g., log-transformed APTT 3.55 vs. 3.55, p = 0.45). However, D-dimer in the cancer groups was significantly greater than that in the noncancer groups (log-transformed 1.83 vs. 1.79, p = 0.009). PT and APTT significantly decreased from 5 h to overnight after edoxaban, but a similar pattern was observed in each group. All adverse events after edoxaban administration were also similar between patients with cancer and noncancer.
Conclusion PT and APTT after edoxaban administration were similar between VTE patients with cancer and noncancer groups, suggesting that edoxaban has anticoagulation effects on cancer-associated VTE similar to those of noncancer patients.

kn-article= en-subject= kn-subject= en-title= kn-title=Quantitative assessment of adhesive effects on partial and full compressive strength of LVL in the edge-wise direction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Laminated wood-based materials have been widely developed, and the laminating process and adhesive itself have been reported to enhance performance beyond the sum of the individual layers' performance. This phenomenon is particularly notable under loads applied in the "edge-wise direction", where each layer bears stress collectively. These combined effects are referred to as the "adhesive effect". Strength under partial compressive loads is critical in timber engineering, as partial compressive stress generates complex stress distributions influenced by boundary conditions. The adhesive effect may also be impacted by these conditions. The aim of this study was to quantitatively and directly evaluate the adhesive effect under partial and full compressive loads using various parameters. The strength of laminated veneer lumber (LVL) with adhesive was compared to that of simply layered veneers without adhesive to assess the adhesive effect. Three mechanisms contributing to the adhesive effect were proposed: Mechanism I, caused by the deformation of the adhesive layer independently from the veneers; Mechanism II, resulting from the adhesive impregnating the veneers; and Mechanism III, arising from the reinforcement provided by adjacent veneers. The results suggested the following: (i) Mechanism I had minimal impact, as the fiber direction and the presence of additional length showed strong and slight effects on the adhesive effect, respectively; (ii) Mechanism II contributed to preventing crack propagation and altering the relationships among mechanical properties, with its effectiveness increasing as the adhesive weight increased; and (iii) Mechanism III functioned as a crossband effect, reinforcing weaknesses caused by the slope of the grain and the angle of the annual rings. en-copyright= kn-copyright= en-aut-name=SudoRyutaro en-aut-sei=Sudo en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoKohta en-aut-sei=Miyamoto en-aut-mei=Kohta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IdoHirofumi en-aut-sei=Ido en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Forestry and Forest Products Research Institute kn-affil= affil-num=3 en-affil=Forestry and Forest Products Research Institute kn-affil= en-keyword=Laminated veneer lumber (LVL) kn-keyword=Laminated veneer lumber (LVL) en-keyword=Partial compressive load kn-keyword=Partial compressive load en-keyword=Bearing strength kn-keyword=Bearing strength en-keyword=Embedment strength kn-keyword=Embedment strength en-keyword=Partial compression perpendicular to grain (PCPG) kn-keyword=Partial compression perpendicular to grain (PCPG) en-keyword=Adhesive layer kn-keyword=Adhesive layer END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=75 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Potential for Radiation Dose Reduction in Temporal Bone CT Imaging Using Photon-Counting Detector CT en-subtitle= kn-subtitle= en-abstract= kn-abstract=Temporal bone computed tomography (CT) is frequently performed for pediatric patients with ear diseases. Advances in CT technology have improved diagnostic imaging quality, but reduction of radiation exposure remains a goal. We evaluated the potential for radiation dose reduction in temporal bone CT examinations using porcine ear ossicles and a photon-counting detector CT system. Three scans of the bilateral temporal bone were performed on each of three pig cadaver heads. In each of seven successive imaging sessions, the radiation dose was reduced by an additional one-seventh of the recommended dose (RD). Two board-certified radiologists independently scored the resulting images on a scale of 1 to 5 points, where 5 represented the image quality at the RD. Images scoring ?4.5 points were considered acceptable. Noise was assessed in a 2-cm-diameter region near the ear ossicles, and standard deviation was measured for each of the seven decrements from the RD. As the radiation dose decreased, the noise progressively increased, and visual assessment scores progressively decreased. Acceptable image scores were obtained at six-sevenths (4.9), five-sevenths (4.8), four-sevenths (4.7), and three-sevenths (4.6) of the RD. Thus, acceptable porcine temporal bone CT images were obtained with a radiation dose reduction of approximately 50%. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HwangSung Il en-aut-sei=Hwang en-aut-mei=Sung Il kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Seoul National University Bundang Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=photon-counting detector computed tomography kn-keyword=photon-counting detector computed tomography en-keyword=ear ossicle kn-keyword=ear ossicle en-keyword=energy-integrating detector computed tomography kn-keyword=energy-integrating detector computed tomography END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enterobacterial common antigen repeat-unit flippase WzxE is required for Escherichia coli growth under acidic conditions, low temperature, and high osmotic stress conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colanic acid and enterobacterial common antigen (ECA) are cell-surface polysaccharides that are produced by many Escherichia coli isolates. Colanic acid is induced under acidic, low temperature, and high-salt conditions and is important for E. coli resistance to these stresses; however, the role of ECA in these stresses is less clear. Here, we observed that knockout of flippase wzxE, which translocates lipid-linked ECA repeat units from the cytoplasmic side of the inner membrane to the periplasmic side, resulted in the sensitivity of E. coli BW25113 to acidic conditions. The wzxE-knockout mutant showed reduced growth potential and viable counts in vegetable extracts with acidic environments, including cherry tomatoes, carrots, celery, lettuce, and spinach. A double-knockout strain of wzxE and wecF (glycosyltransferase that adds the third-and-final sugar of the lipid-linked ECA repeat unit) was not sensitive to acidic conditions, with similar results obtained for a double-knockout strain of wzxE and wcaJ (glycosyltransferase that initiates colanic acid lipid-linked repeat-unit biosynthesis). The wzxE-knockout mutant was sensitive to low temperatures or high-salt conditions, which induced colanic acid synthesis, and these sensitivities were abolished by the additional knockout of wcaJ. These results suggest that lipid-linked ECA repeat units confer E. coli susceptibility to acidic, low temperatures, and high-salt conditions in a colanic acid-dependent manner and that wzxE suppresses this negative effect. en-copyright= kn-copyright= en-aut-name=YamaguchiSaki en-aut-sei=Yamaguchi en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=wzxE flippase kn-keyword=wzxE flippase en-keyword=enterobacterial common antigen kn-keyword=enterobacterial common antigen en-keyword=low pH kn-keyword=low pH en-keyword=low temperature kn-keyword=low temperature en-keyword=hyperosmotic stress kn-keyword=hyperosmotic stress END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=7 article-no= start-page=2287 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Midazolam and Diazepam for Sedation in Patients Undergoing Double-Balloon Endoscopic Retrograde Cholangiopancreatography: A Propensity Score-Matched Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The sedation method used in double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) varies across countries and between healthcare facilities. No previous studies have compared the effects of different benzodiazepines on sedation during endoscopic procedures. This study aimed to compare the effects of midazolam and diazepam sedation on DB-ERCP outcomes. Methods: This retrospective cohort study analyzed consecutive patients who underwent DB-ERCP between January 2017 and February 2024. A total of 203 patients who were sedated with diazepam (n = 94) or midazolam (n = 109) were analyzed. Propensity score matching was applied to adjust for baseline group differences. The primary outcome was the incidence of sedation-related adverse events (AEs). Secondary outcomes included inadequate sedation requiring additional sedatives and risk factors for sedation-related AEs. Results: Sedation-related AEs were more frequent with diazepam (28% [21/75]) than with midazolam (14% [11/75]; p = 0.046). Hypoxia occurred more frequently with diazepam (19% [14/75]) than with midazolam (5% [4/75]; p = 0.012). However, no significant differences were observed between the two groups for hypotension (p = 0.41) and bradycardia (p = 1.0). Poor sedation requiring other sedatives occurred significantly more often with diazepam (8% [6/75]) compared with midazolam sedation (0% [0/75], p = 0.012). Multivariate analysis identified diazepam sedation (odds ratio, 2.3; 95% confidence interval, 1.0-5.3; p = 0.048) as the sole risk factor for sedation-related AEs. Conclusions: Midazolam is safer and more effective than diazepam sedation in patients undergoing DB-ERCP. en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=adverse events kn-keyword=adverse events en-keyword=balloon-assisted ERCP kn-keyword=balloon-assisted ERCP en-keyword=benzodiazepine kn-keyword=benzodiazepine en-keyword=sedation kn-keyword=sedation END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=4 article-no= start-page=e82348 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bilateral Scleritis and Neutrophilic Dermatosis With Cytogenetic Chromosomal Aberrancy Related to Pyoderma Gangrenosum: A Case Report of a 20-Year Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pyoderma gangrenosum is a non-infectious autoimmune disease with skin plaques and ulcers in the entity of neutrophilic dermatosis and may have a background of myelodysplastic syndromes. This study reported a 20-year follow-up of a patient with pyoderma gangrenosum and scleritis who showed chromosomal aberrancy from the initial phase and later in the course developed thrombocythemia. A 51-year-old man presented with widespread indurated erythematous plaques with scaling and pustules on the forehead, bilateral eyelids, and nasal bridge, in addition to nodular scleritis in the left eye and ulcer formation of the plaques in the lower legs. Skin biopsy revealed massive dermal infiltration mainly with neutrophils in the absence of neutrophilic vasculitis. Suspected of myelodysplastic syndromes, bone marrow biopsy was normal, while chromosomal aberrancy, 46, XY, del (20) (q11q13.3), was detected. In the diagnosis of neutrophilic dermatosis, probably of pyoderma gangrenosum, he began to have oral prednisolone 20 mg daily and colchicine 1 mg daily, leading to the subsidence of skin lesions. Four months later, he developed nodular scleritis in the right eye and began to use topical 0.1% betamethasone in both eyes. He was stable with only prednisolone 12.5 mg daily until the age of 55.5 years, when he showed an increase of serum lactate dehydrogenase. The bone marrow aspirate disclosed neither blast cell increase nor atypical cells. The same chromosomal aberrancy was repeatedly detected. One year later, he developed breathing difficulty and underwent tracheostomy. Laryngeal lesion biopsy disclosed squamous cell papilloma with human papillomavirus-6. At 60 years old, he showed marginal corneal infiltration in the left eye, and at 61 years old, hypopyon in the right eye. Platelets tended to increase up to 1000 × 103/?L, and bone marrow examinations were recommended but refused by the patient. At the latest follow-up at 71 years old, he was ambulatory in health and stable with a tracheostomy cannula. In conclusion, pyoderma gangrenosum with scleritis occurred in an undetermined hematological malignancy with chromosomal aberrancy. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OmichiRyotaro en-aut-sei=Omichi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwatsukiKeiji en-aut-sei=Iwatsuki en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Internal Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Otolaryngology, Head and Neck Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=corneal infiltration kn-keyword=corneal infiltration en-keyword=hypopyon kn-keyword=hypopyon en-keyword=myelodysplastic syndromes kn-keyword=myelodysplastic syndromes en-keyword=neutrophilic dermatosis kn-keyword=neutrophilic dermatosis en-keyword=peripheral keratitis kn-keyword=peripheral keratitis en-keyword=pyoderma gangrenosum kn-keyword=pyoderma gangrenosum en-keyword=scleritis kn-keyword=scleritis en-keyword=sweet syndrome kn-keyword=sweet syndrome END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Corporate decision-making process for exploration time kn-title=知の探索時間についての企業の意思決定プロセス en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order for companies to innovate through business co-creation, it is necessary to explore a wide range of external knowledge and technologies. However, there is no clear answer as to how much time should be spent for exploration. Under these circumstances, companies must take into account constraints such as the amount of management resources that can be invested, and make decisions about the time to spend for exploration. The purpose of this paper is to clarify the process of how companies that have introduced corporate accelerator program recognize the relationship between the program period and the results of business co-creation, and how they make decisions about the program period. We conducted a case study of several companies that have introduced corporate accelerator program in Japan. In addition, this paper established a hypothesis about decision-making about the time for exploration from case studies. en-copyright= kn-copyright= en-aut-name=SHIMIZUTakeshi en-aut-sei=SHIMIZU en-aut-mei=Takeshi kn-aut-name=志水武史 kn-aut-sei=志水 kn-aut-mei=武史 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems Okayama University kn-affil=国立大学法人岡山大学学術研究院ヘルスシステム統合科学研究学域 en-keyword=corporate accelerator program kn-keyword=corporate accelerator program en-keyword=co-creation kn-keyword=co-creation en-keyword=exploration kn-keyword=exploration en-keyword=Time Compression Diseconomies kn-keyword=Time Compression Diseconomies END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=4 article-no= start-page=e70139 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Induction Therapy With Oral Tacrolimus Provides Long-Term Benefit in Thiopurine-Na?ve Refractory Ulcerative Colitis Patients Despite Low Serum Albumin Levels en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: Oral tacrolimus is an effective treatment for refractory ulcerative colitis (UC). However, tacrolimus is underutilized because of the difficulties in transitioning to subsequent maintenance therapy and concerns about adverse events.
Methods: We evaluated the clinical outcomes, adverse events, and accumulated medication costs in consecutive 72 UC patients treated with tacrolimus.
Results: Fifty-five (76%) patients with pancolitis and 43 (60%) patients with acute severe disease were entered. Fifty-four (75%) achieved clinical remission 8 weeks after starting tacrolimus. At the last visit, 62 (86%) patients had colectomy-free remission, and 55 (76%) patients had corticosteroid-free remission. Eighteen (25%) patients maintained remission without additional treatment after tacrolimus discontinuation. Patients with continuous remission had a significantly lower history of thiopurine use and lower serum albumin levels at the induction of tacrolimus than patients with failure to induce or maintain remission. No severe adverse events due to tacrolimus treatment were observed. The accumulated medication costs over 3 years in patients with continuous remission after the start of tacrolimus were lower than those in patients with induction and maintenance of infliximab (p < 0.001).
Conclusions: Tacrolimus could have an irreplaceable role in the era of biologic therapies, especially for refractory UC patients with thiopurine-na & iuml;ve and low serum albumin levels. en-copyright= kn-copyright= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=biologics therapy kn-keyword=biologics therapy en-keyword=tacrolimus kn-keyword=tacrolimus en-keyword=thiopurine kn-keyword=thiopurine en-keyword=ulcerative colitis kn-keyword=ulcerative colitis END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=3 article-no= start-page=143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Hair Drawing Evaluation Algorithm for Exactness Assessment Method in Portrait Drawing Learning Assistant System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, portrait drawing has become increasingly popular as a means of developing artistic skills and nurturing emotional expression. However, it is challenging for novices to start learning it, as they usually lack a solid grasp of proportions and structural foundations of the five senses. To address this problem, we have studied Portrait Drawing Learning Assistant System (PDLAS) for guiding novices by providing auxiliary lines of facial features, generated by utilizing OpenPose and OpenCV libraries. For PDLAS, we have also presented the exactness assessment method to evaluate drawing accuracy using the Normalized Cross-Correlation (NCC) algorithm. It calculates the similarity score between the drawing result and the initial portrait photo. Unfortunately, the current method does not assess the hair drawing, although it occupies a large part of a portrait and often determines its quality. In this paper, we present a hair drawing evaluation algorithm for the exactness assessment method to offer comprehensive feedback to users in PDLAS. To emphasize hair lines, this algorithm extracts the texture of the hair region by computing the eigenvalues and eigenvectors of the hair image. For evaluations, we applied the proposal to drawing results by seven students from Okayama University, Japan and confirmed the validity. In addition, we observed the NCC score improvement in PDLAS by modifying the face parts with low similarity scores from the exactness assessment method. en-copyright= kn-copyright= en-aut-name=ZhangYue en-aut-sei=Zhang en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FebriantiErita Cicilia en-aut-sei=Febrianti en-aut-mei=Erita Cicilia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SudarsonoAmang en-aut-sei=Sudarsono en-aut-mei=Amang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HsuChenchien en-aut-sei=Hsu en-aut-mei=Chenchien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Electrical Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=4 en-affil=Department of Electrical Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=5 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=portrait drawing kn-keyword=portrait drawing en-keyword=auxiliary lines kn-keyword=auxiliary lines en-keyword=OpenPose kn-keyword=OpenPose en-keyword=OpenCV kn-keyword=OpenCV en-keyword=normalized cross-correlation (NCC) kn-keyword=normalized cross-correlation (NCC) en-keyword=hair texture kn-keyword=hair texture en-keyword=exactness assessment method kn-keyword=exactness assessment method END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=6 article-no= start-page=2485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vesicular Glutamate Transporter 3 Is Involved in Glutamatergic Signalling in Podocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glomerular podocytes act as a part of the filtration barrier in the kidney. The activity of this filter is regulated by ionotropic and metabotropic glutamate receptors. Adjacent podocytes can potentially release glutamate into the intercellular space; however, little is known about how podocytes release glutamate. Here, we demonstrated vesicular glutamate transporter 3 (VGLUT3)-dependent glutamate release from podocytes. Immunofluorescence analysis revealed that rat glomerular podocytes and an immortal mouse podocyte cell line (MPC) express VGLUT1 and VGLUT3. Consistent with this finding, quantitative RT-PCR revealed the expression of VGLUT1 and VGLUT3 mRNA in undifferentiated and differentiated MPCs. In addition, the exocytotic proteins vesicle-associated membrane protein 2, synapsin 1, and synaptophysin 1 were present in punctate patterns and colocalized with VGLUT3 in MPCs. Interestingly, approximately 30% of VGLUT3 colocalized with VGLUT1. By immunoelectron microscopy, VGLUT3 was often observed around clear vesicle-like structures in differentiated MPCs. Differentiated MPCs released glutamate following depolarization with high potassium levels and after stimulation with the muscarinic agonist pilocarpine. The depletion of VGLUT3 in MPCs by RNA interference reduced depolarization-dependent glutamate release. These results strongly suggest that VGLUT3 is involved in glutamatergic signalling in podocytes and may be a new drug target for various kidney diseases. en-copyright= kn-copyright= en-aut-name=NishiiNaoko en-aut-sei=Nishii en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiTomoko en-aut-sei=Kawai en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuokaHiroki en-aut-sei=Yasuoka en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeTadashi en-aut-sei=Abe en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TatsumiNanami en-aut-sei=Tatsumi en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaYuika en-aut-sei=Harada en-aut-mei=Yuika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LiShunai en-aut-sei=Li en-aut-mei=Shunai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsukanoMoemi en-aut-sei=Tsukano en-aut-mei=Moemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OgawaDaisuke en-aut-sei=Ogawa en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TakeiKohji en-aut-sei=Takei en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YamadaHiroshi en-aut-sei=Yamada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cell Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Genomics and Proteomics, Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Department of Genomics and Proteomics, Advanced Science Research Center, Okayama University kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Central Research Laboratory, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=VGLUT3 kn-keyword=VGLUT3 en-keyword=glutamate kn-keyword=glutamate en-keyword=podocyte kn-keyword=podocyte en-keyword=glutamatergic transmission kn-keyword=glutamatergic transmission END start-ver=1.4 cd-journal=joma no-vol=301 cd-vols= no-issue=4 article-no= start-page=108334 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of basic amino acid residues in substrate binding and transport of the light-driven anion pump Synechocystis halorhodopsin (SyHR) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microbial rhodopsins are photoreceptive seventransmembrane a-helical proteins, many of which function as ion transporters, primarily for small monovalent ions such as Na+, K+, Cl-, Br-, and I-. Synechocystis halorhodopsin (SyHR), identified from the cyanobacterium Synechocystis sp. PCC 7509, uniquely transports the polyatomic divalent SO42- inward, in addition to monovalent anions (Cl- and Br-). In this study, we conducted alanine-scanning mutagenesis on twelve basic amino acid residues to investigate the anion transport mechanism of SyHR. We quantitatively evaluated the Cl-and SO42- transport activities of the WT SyHR and its mutants. The results showed a strong correlation between the Cl-and SO42- transport activities among them (R = 0.94), suggesting a shared pathway for both anions. Notably, the R71A mutation selectively abolished SO42- transport activity while maintaining Cl- transport, whereas the H167A mutation significantly impaired both Cl-and SO42- transport. Furthermore, spectroscopic analysis revealed that the R71A mutant lost its ability to bind SO42- due to the absence of a positive charge, while the H167A mutant failed to accumulate the O intermediate during the photoreaction cycle (photocycle) due to reduced hydrophilicity. Additionally, computational analysis revealed the SO42- binding modes and clarified the roles of residues involved in its binding around the retinal chromophore. Based on these findings and previous structural information, we propose that the positive charge and hydrophilicity of Arg71 and His167 are crucial for the formation of the characteristic initial and transient anion-binding site of SyHR, enabling its unique ability to bind and transport both Cl-and SO42-. en-copyright= kn-copyright= en-aut-name=NakamaMasaki en-aut-sei=Nakama en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NojiTomoyasu en-aut-sei=Noji en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshizawaSusumu en-aut-sei=Yoshizawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshikitaHiroshi en-aut-sei=Ishikita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SudoYuki en-aut-sei=Sudo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, The University of Tokyo kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, The University of Tokyo kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=microbial rhodopsin kn-keyword=microbial rhodopsin en-keyword=anion transport kn-keyword=anion transport en-keyword=retinal kn-keyword=retinal en-keyword=membrane protein kn-keyword=membrane protein en-keyword=photobiology kn-keyword=photobiology END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=6 article-no= start-page=1082 end-page=1096 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Myeloid Cells Induce Infiltration and Activation of B Cells and CD4+ T Follicular Helper Cells to Sensitize Brain Metastases to Combination Immunotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brain metastasis is a poor prognostic factor in patients with cancer. Despite showing efficacy in many extracranial tumors, immunotherapy with anti?PD-1 mAb or anti?CTLA4 mAb seems to be less effective against intracranial tumors. Promisingly, recent clinical studies have reported that combination therapy with anti?PD-1 and anti?CTLA4 mAbs has a potent antitumor effect on brain metastasis, highlighting the need to elucidate the detailed mechanisms controlling the intracranial tumor microenvironment (TME) to develop effective immunotherapeutic strategies. In this study, we analyzed the tumor-infiltrating lymphocytes in murine models of brain metastasis that responded to anti?CTLA4 and anti?PD-1 mAbs. Activated CD4+ T follicular helper (TFH) cells with high CTLA4 expression characteristically infiltrated the intracranial TME, which were activated by combination anti?CTLA4 and anti?PD-1 treatment. The loss of TFH cells suppressed the additive effect of CTLA4 blockade on anti?PD-1 mAb. B-cell?activating factor belonging to the TNF family (BAFF) and a proliferation-inducing ligand (APRIL) produced by abundant myeloid cells, particularly CD80hiCD206lo proinflammatory M1-like macrophages, in the intracranial TME induced B-cell and TFH-cell infiltration and activation. Furthermore, the intracranial TME of patients with non?small cell lung cancer featured TFH- and B-cell infiltration as tertiary lymphoid structures. Together, these findings provide insights into the immune cell cross-talk in the intracranial TME that facilitates an additive antitumor effect of CTLA4 blockade with anti?PD-1 treatment, supporting the potential of a combination immunotherapeutic strategy for brain metastases.
Significance: B-cell and CD4+ T follicular helper cell activation via BAFF/APRIL from abundant myeloid cells in the intracranial tumor microenvironment enables a combinatorial effect of CTLA4 and PD-1 blockade in brain metastases. en-copyright= kn-copyright= en-aut-name=NinomiyaToshifumi en-aut-sei=Ninomiya en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Educational Needs and Support of Children with Cancer kn-title=小児がん患児に対する教育的支援とその研究動向 en-subtitle= kn-subtitle= en-abstract= In this study, we summarized research trends related to the educational needs and support of children with cancer from the perspectives of “learning,” “self-management,” “interpersonal,” “psychological,” and “collaboration,”. In terms of learning, the study showed that experiential learning and distance education are solutions to the problem of delayed learning due to prolonged absence from school and poor concentration during treatment. Next, in self-management, it is important to educate affected children so that they can fully understand the disease and treatment. In addition, in terms of interpersonal support, it is difficult for the affected patients to build relationships with friends, but providing opportunities for interaction is expected to contribute to the improvement of interpersonal relationships. In terms of psychological support, the anxiety associated with treatment is a major psychological burden for the affected children, and the understanding of their friends and the intervention of university student volunteers are effective in helping them achieve psychological stability. Finally, the lack of cooperation between medical institutions and schools was highlighted as a deficiency in the support system, which needs to be strengthened. In the future, these support measures should be empirically verified to establish a sustainable support system. kn-abstract= 本研究は、小児がん患児の教育的支援に関する研究の動向を明らかにし、今後の課題とその解決策を提起することを目的とした。「学習」、「自己管理」、「対人」、「心理」、「連携」の5つの視点から分析を行った。学習支援について、治療に伴う学習の遅れや集中力の低下に対し、個別の教育支援計画や体験的な学習、および遠隔教育の実施に期待されていた。自己管理支援では、患児が自身の病状や治療による副作用を理解し、自立的に管理できる能力を育成することが求められていた。対人支援について、患児の長期入院により、友人関係の構築が困難になり、入院中や復学後のコミュニケーションの支援が重要であることが確認された。心理支援においては、周囲への効果的ながん教育や大学生ボランティアによる支援が、患児の心理的安定を促すことが示された。最後に、学校と医療機関、保護者の連携不足が指摘されており、連携ツールの開発が求められている。 en-copyright= kn-copyright= en-aut-name=CHENYiwen en-aut-sei=CHEN en-aut-mei=Yiwen kn-aut-name=陳依文 kn-aut-sei=陳 kn-aut-mei=依文 aut-affil-num=1 ORCID= en-aut-name=YOSHITOSHIMunehisa en-aut-sei=YOSHITOSHI en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education Doctoral Programs, Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院連合学校教育学研究科博士課程 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=小児がん (child hood cancer) kn-keyword=小児がん (child hood cancer) en-keyword=慢性疾患 (chronic illness) kn-keyword=慢性疾患 (chronic illness) en-keyword=教育的ニーズ (educational needs) kn-keyword=教育的ニーズ (educational needs) en-keyword=研究動向 (research trends) kn-keyword=研究動向 (research trends) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=297 end-page=311 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Exploring Home Learning That Bridges Lessons to Foster Autonomous and Self-Directed Learning kn-title=主体的・自律的な学びを萌芽させる「授業と授業をつなぐ家庭学習」の探究 en-subtitle= kn-subtitle= en-abstract= For students to develop the ability to learn independently, they need learning experiences that extend beyond the classroom, including at home. In other words, learning is not confined to the classroom but is reinforced through a wide range of activities. This study aimed to nurture “autonomous and self-directed learning” among students in the second grade at a public junior high school by integrating classroom and home learning. Teachers emphasized the importance of learning strategies and goal setting, and encouraged metacognition. As a result, students became more aware of the self-regulated learning cycle and began exploring learning strategies tailored to their needs. In addition, working at home on assignments connected to the class not only increased students’ active participation in class but also improved their motivation to learn independ ently outside of class. kn-abstract= 生徒が自ら学習を進めていく力を身に付けるには,授業内だけでなく,家庭など授業外の場での学習経験を積む必要がある。つまり,学習は授業内だけで完結するのではなく,広範な活動を通して成立する。本研究では,公立中学校の第2学年を対象に授業と家庭学習を連携させる実践を行い,生徒の「主体的・自律的な学び」を萌芽させることを目指した。教師が学習方略や目標設定の重要性を伝え,メタ認知を促すことで,生徒は自己調整学習のサイクルを意識し,自分なりの学習方略を探求するようになった。また,家庭学習で授業につながる課題に取り組むことで,授業への主体的な参加と,授業外で自律的に学ぶ意欲が促されることも示唆された。 en-copyright= kn-copyright= en-aut-name=TANAKAJunko en-aut-sei=TANAKA en-aut-mei=Junko kn-aut-name=田中純子 kn-aut-sei=田中 kn-aut-mei=純子 aut-affil-num=1 ORCID= en-aut-name=MISAWARyo en-aut-sei=MISAWA en-aut-mei=Ryo kn-aut-name=三沢良 kn-aut-sei=三沢 kn-aut-mei=良 aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama Municipal Hosen Junior High School kn-affil=岡山市立芳泉中学校 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) kn-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) en-keyword=自己調整学習 (self-regulated learning) kn-keyword=自己調整学習 (self-regulated learning) en-keyword=宿題 (homework) kn-keyword=宿題 (homework) en-keyword=授業改善 (lesson improvement) kn-keyword=授業改善 (lesson improvement) END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=2480231 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Specific enhancement of the translation of thermospermine-responsive uORF-containing mRNAs by ribosomal mutations in Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=Auxin-induced xylem formation in angiosperms is negatively regulated by thermospermine, whose biosynthesis is also induced by auxin. In Arabidopsis thaliana, loss-of-function mutants of ACL5, which encodes thermospermine synthase, exhibit a dwarf phenotype accompanied by excessive xylem formation. Studies of suppressor mutants that recover from the acl5 dwarf phenotype suggest that thermospermine alleviates the inhibitory effect of an upstream open-reading frame (uORF) on the main ORF translation of SAC51 mRNA. Many suppressor mutations for acl5 have been mapped to the uORF conserved in the SAC51 family or to ribosomal protein genes, such as RPL10A, RPL4A, and RACK1A. In this study, we identified newly isolated acl5 suppressors, sac501, sac504, and sac506, which are additional alleles of RPL10A and the uORFs of SAC51 family members, SACL1 and SACL3, respectively. To investigate whether acl5-suppressor alleles of ribosomal genes broadly affect translation of uORF-containing mRNAs, we examined GUS activity in several 5'-GUS fusion constructs. Our results showed that these alleles enhanced GUS activity in SAC51 and SACL3 5'-fusion constructs but had no effect on other 5'-fusion constructs unrelated to thermospermine response. This suggests that these ribosomal proteins are specifically involved in the thermospermine-mediated regulation of mRNA translation. en-copyright= kn-copyright= en-aut-name=MutsudaKoki en-aut-sei=Mutsuda en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiYuichi en-aut-sei=Nishii en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyoshimaTomohiko en-aut-sei=Toyoshima en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaHiroko en-aut-sei=Fukushima en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MotoseHiroyasu en-aut-sei=Motose en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiTaku en-aut-sei=Takahashi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=mRNA translation kn-keyword=mRNA translation en-keyword=RPL10 kn-keyword=RPL10 en-keyword=suppressor mutant kn-keyword=suppressor mutant en-keyword=thermospermine kn-keyword=thermospermine en-keyword=uORF kn-keyword=uORF END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=3 article-no= start-page=15 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Survival, Creation, and Disappearance of Manufacturing Firms in the First Stage of Regional Revitalization kn-title=地方創生第1期における製造事業所の存続,発生,消失 en-subtitle= kn-subtitle= en-abstract= In many local municipalities, in addition to revitalizing existing businesses and creating new businesses, attracting manufacturing plants remains an important policy for regional development. Today, unlike the attraction of heavy, large-scale industries during the period of high economic growth, there is a trend to attract companies by making the most of the region's advantages. Although the job creation effect has become smaller than in the past, many manufacturing industries remain positioned as core industries in the region. During the first period of regional revitalization, we identify what manufacturing firms have disappeared, withdrawn, appeared, or survived in what regions, and analyze the factors behind those.
 Comparing manufacturing firms in 2014 and 2019, the average of value-added and the distribution of that shows that manufacturing firms that existed in both 2014 and 2019 had the highest labor productivity. The next highest was manufacturing firms that existed in 2019, and the lowest was manufacturing firms that existed in 2014 but did not exist in 2019. In addition, the results of the logit analysis suggest that manufacturing firms with high productivity and large size tend not to disappear, and that manufacturing firms with a high degree of urbanization tend to disappear. On the other hand, a regression analysis at the city/town/village level using industry concentration by industry and urban concentration measured by population size as explanatory variables showed a positive effect on the number of manufacturing firms that had been established. kn-abstract= 地方に位置する多くの自治体においては,従来からある事業所の活性化や新規事業所の誕生に加えて,製造工場の誘致は地域振興にとっていまも重要な政策となっている。今日,高度経済成長期における重厚長大型の産業の誘致とは異なり,地域優位性をできるだけ活用した企業誘致の傾向になっている。雇用創出効果は昔に比べて小さくなっているとはいえ,製造業の多くにおいて,地域の基盤産業としての位置づけは残っている。第1期の地方創生の期間で,どのような地域において,どのような製造工場が消失,撤退や出現,存続しているのかを識別し,それらの要因を分析する。
 2014年と2019年の事業所の比較において,付加価値生産性の平均と分布を見ると2014年,2019年ともに存在する事業所の労働生産性が最も高い。次いで高いのが2019年に存在する事業所で,最も低かったのが2014年には存在したが2019年には存在していない事業所であった。またロジット分析の結果から,生産性が高く事業所規模が大きいと消滅しない傾向があり,また都市化の程度が高いと消滅傾向にあることが推定された。他方,発生した製造事業所について,産業別に同業種集積と人口規模で測った都市集積を説明変数とした市町村単位の回帰分析からは正の効果が示された。 en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=3 article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Market Segmentation and Market Reactions to Earnings Announcements: A Quarterly Analysis kn-title=市場区分と決算発表に対する市場の反応 ―四半期データを利用した分析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to examine, using quarterly financial data, how the market reaction to earnings announcements in each market segment (prime market segment, standard market segment, and growth market segment) has changed after the revision of market segmentation at the Tokyo Stock Exchange. For the research design, the abnormal volume and residual returns for the 12 quarters around April 1, 2022, when the market segmentation was changed, were calculated using the analysis method of Beaver et al. [2020]. The results of the analysis suggest that volume is significantly affected by changes in market segmentation. In addition, for the group of stocks in the growth market, there appears to have been some change in the trend of stock price fluctuations after the market segmentation revision. en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=YamanishiYuki en-aut-sei=Yamanishi en-aut-mei=Yuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=2 ORCID= en-aut-name=KobayashiHiroaki en-aut-sei=Kobayashi en-aut-mei=Hiroaki kn-aut-name=小林裕明 kn-aut-sei=小林 kn-aut-mei=裕明 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=熊本県立大学総合管理学部 affil-num=3 en-affil= kn-affil=青山学院大学大学院会計プロフェッション研究科 END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=3 article-no= start-page=102660 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intention and potential determinants of COVID-19 vaccination among healthcare workers at a single university hospital in Japan, 2024?2025 pre-season en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Financial accessibility has emerged as a significant barrier to vaccine uptake following the cessation of universal public funding for coronavirus disease 2019 (COVID-19) vaccination programs. This investigation assessed the intention and determinant factors of COVID-19 vaccination among healthcare workers in Japan in the 2024?2025 pre-season.
Methods: A retrospective survey was conducted utilizing data collected from hospital staff at Okayama University Hospital, Japan, to inform the COVID-19 vaccination strategy in October 2024. The analysis evaluated demographic characteristics, vaccine intention, perceived barriers to vaccination, and maximum acceptable out-of-pocket expenditure.
Results: The study population of 3417 respondents comprised 843 medical doctors (24.7 %), 1131 nurses (33.1 %), 320 other medical staff (9.4 %), 286 dental doctors (8.4 %), and 627 administrative officers (18.3 %). At full cost, 2109 (61.7 %) indicated no intention to receive vaccination, while only 4.4 % expressed willingness to be vaccinated and 33.9 % remained undecided. With total self-payment, the vaccination acceptance rates were the highest and lowest among medical doctors (11.4 %) and nurses (1.0 %), respectively. Cost (38.1 %), followed by safety issues (29.5 %) and concerns regarding efficacy or medical necessity (20.3 %), emerged as the primary barrier. The projected vaccination intention increased to 43.9 % and 54.9 % at reduced self-pay costs of 3000 JPY and 5000 JPY, respectively.
Conclusions: Addressing financial constraints through policy interventions could be effective strategies in increasing overall vaccination coverage among healthcare workers. In addition, providing tailored education on vaccine safety, efficacy, and necessity may further facilitate increased vaccine uptake within this critical population. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaYasushi en-aut-sei=Fujita en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KiguchiTakashi en-aut-sei=Kiguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ManabeYohei en-aut-sei=Manabe en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Infection Prevention and Control, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Infection Prevention and Control, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Infection Prevention and Control, Okayama University Hospital kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=Immunization kn-keyword=Immunization en-keyword=Reimbursement kn-keyword=Reimbursement en-keyword=Healthcare workers kn-keyword=Healthcare workers en-keyword=Financial support kn-keyword=Financial support END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A randomized controlled trial of conventional GVHD prophylaxis with or without teprenone for the prevention of severe acute GVHD en-subtitle= kn-subtitle= en-abstract= kn-abstract=Therapies that effectively suppress graft-versus-host disease (GVHD) without compromising graft-versus-leukemia/lymphoma (GVL) effects is important in allogeneic hematopoietic stem cell transplantation (allo-HSCT) for hematopoietic malignancies. Geranylgeranylacetone (GGA) is a main component of teprenone, a gastric mucosal protectant commonly used in clinical practice. In preclinical models, GGA suppresses proinflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α), which are associated with GVHD as well as induces thioredoxin-1 (Trx-1), which suppresses GVHD while maintaining GVL effects. Here, we investigated whether the addition of teprenone to standard GVHD prophylaxis could reduce the cumulative incidence of severe acute GVHD (aGVHD) without attenuating GVL effects. This open-label, randomized clinical trial enrolled 40 patients (21 control and 19 teprenone group) who received allo-HSCT between May 2022 and February 2023 in our institution. Patients in the teprenone group received 50 mg of teprenone orally thrice daily for 21 days from the initiation of the conditioning regimen. The cumulative incidence of severe aGVHD by day 100 after allo-HSCT was not significantly different in the two groups (27.9 vs. 16.1%, p?=?0.25). The exploratory studies revealed no obvious changes in Trx-1 levels, but the alternations from baseline in IL-1β and TNF-α levels at day 28 after allo-HSCT tended to be lower in the teprenone group. In conclusion, we could not demonstrate that teprenone significantly prevented the development of severe aGVHD. Discrepancy with preclinical model suggests that appropriate dose of teprenone may be necessary to induce the expression of antioxidant enzymes that suppress severe aGVHD.

Despite their generally indolent nature, certain SELs, such as gastrointestinal stromal tumors, require resection. Current guidelines recommend periodic surveillance; however, the natural course and long-term outcomes of gastric SELs have not been sufficiently investigated. This systematic review aimed to synthesize evidence on the progression, growth rate, and risk factors associated with gastric SELs to inform clinical management strategies. Methods: A comprehensive search of PubMed was conducted for peer-reviewed studies published between January 2000 and November 2024. Eligible studies included original studies on the follow-up and progression of gastric SELs. Non-English articles, reviews, case reports, and unrelated topics were excluded. In total, 277 articles were screened, with 15 additional articles identified through manual screening. Ultimately, 41 articles were included in the analysis. The study protocol is registered in PROSPERO (CRD42024614865). Results: Large-scale studies reported low growth rates of 2.0-8.5% over 2.0-5.0 years, while smaller studies reported a broader range of growth rates of 5.4-28.4%. The factors contributing to these discrepancies include patient selection, follow-up duration, and growth criteria. Risk factors for lesion size increase include larger initial lesion size, irregular margins, heterogeneous echo patterns, and certain tumor locations. Conclusions: These findings underscore the need for individualized management strategies based on lesion size, imaging characteristics, and risk factors. The close monitoring of high-risk lesions is crucial for timely intervention. Standardized growth criteria and optimized follow-up protocols are essential for improving clinical decision making and patient outcomes. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=gastric lesions kn-keyword=gastric lesions en-keyword=gastrointestinal stromal tumor kn-keyword=gastrointestinal stromal tumor en-keyword=subepithelial lesion kn-keyword=subepithelial lesion en-keyword=submucosal tumor kn-keyword=submucosal tumor END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=2 article-no= start-page=108 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Implementation of Sensor Input Setup Assistance Service Using Generative AI for SEMAR IoT Application Server Platform en-subtitle= kn-subtitle= en-abstract= kn-abstract=For rapid deployments of various IoT application systems, we have developed Smart Environmental Monitoring and Analytical in Real-Time (SEMAR) as an integrated server platform. It is equipped with rich functions for collecting, analyzing, and visualizing various data. Unfortunately, the proper configuration of SEMAR with a variety of IoT devices can be complex and challenging for novice users, since it often requires technical expertise. The assistance of Generative AI can be helpful to solve this drawback. In this paper, we present an implementation of a sensor input setup assistance service for SEMAR using prompt engineering techniques and Generative AI. A user needs to define the requirement specifications and environments of the IoT application system for sensor inputs, and give them to the service. Then, the service provides step-by-step guidance on sensor connections, communicating board configurations, network connections, and communication protocols to the user, which can help the user easily set up the configuration to connect the relevant devices to SEMAR. For evaluations, we applied the proposal to the input sensor setup processes of three practical IoT application systems with SEMAR, namely, a smart light, water heater, and room temperature monitoring system. In addition, we applied it to the setup process of an IoT application system for a course for undergraduate students at the Insitut Bisnis dan Teknologi (INSTIKI), Indonesia. The results demonstrate the effectiveness of the proposed service for SEMAR. en-copyright= kn-copyright= en-aut-name=KotamaI. Nyoman Darma en-aut-sei=Kotama en-aut-mei=I.

So, iMCD-TAFRO is an aggressive subtype of iMCD with TAFRO syndrome and often hyper-vascularized lymph nodes. Since we proposed diagnostic criteria of iMCD-TAFRO in 2016, we have accumulated new insights on the disorder and additional cases have been reported worldwide. In this systematic review and cohort analysis, we established and validated a definition for iMCD-TAFRO. First, we searched PubMed and Japan Medical Abstracts Society databases using the keyword “TAFRO” to extract cases. Patients with possible systemic autoimmune diseases and hematologic malignancies were excluded. Our search identified 54 cases from 50 articles. We classified cases into three categories: (1) iMCD-TAFRO (TAFRO syndrome with lymph node histopathology consistent with iMCD), (2) possible iMCD-TAFRO (TAFRO syndrome with no lymph node biopsy performed and no other co-morbidities), and (3) TAFRO without iMCD or other co-morbidities (TAFRO syndrome with lymph node histopathology not consistent with iMCD or other comorbidities). Based on the findings, we propose an international definition requiring four clinical criteria (thrombocytopenia, anasarca, fever/hyperinflammatory status, organomegaly), renal dysfunction or characteristic bone marrow findings, and lymph node features consistent with iMCD. The definition was validated with an external cohort (the ACCELERATE Natural History Registry). The present international definition will facilitate a more precise and comprehensive approach to the diagnosis of iMCD-TAFRO. en-copyright= kn-copyright= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FajgenbaumDavid C. en-aut-sei=Fajgenbaum en-aut-mei=David C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PiersonSheila K. en-aut-sei=Pierson en-aut-mei=Sheila K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwakiNoriko en-aut-sei=Iwaki en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawanoMitsuhiro en-aut-sei=Kawano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraNaoya en-aut-sei=Nakamura en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IzutsuKoji en-aut-sei=Izutsu en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakeuchiKengo en-aut-sei=Takeuchi en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YoshizakiKazuyuki en-aut-sei=Yoshizaki en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OksenhendlerEric en-aut-sei=Oksenhendler en-aut-mei=Eric kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=van RheeFrits en-aut-sei=van Rhee en-aut-mei=Frits kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Cytokine Storm Treatment & Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=3 en-affil=Center for Cytokine Storm Treatment & Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=4 en-affil=Hematology/Respiratory Medicine, Kanazawa University Graduate School of Medical Science kn-affil= affil-num=5 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Rheumatology, Kanazawa University Graduate School of Medical Science kn-affil= affil-num=7 en-affil=Department of Pathology, Tokai University School of Medicine kn-affil= affil-num=8 en-affil=Department of Hematology, National Cancer Center Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, The Cancer Institute Hospital of Japanese Foundation for Cancer Research kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Organic Fine Chemicals, Institute of Scientific and Industrial Research, Osaka University kn-affil= affil-num=14 en-affil=Department of Clinical Immunology, H?pital Saint-Louis kn-affil= affil-num=15 en-affil=Myeloma Center, University of Arkansas for Medical Sciences kn-affil= affil-num=16 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=4 article-no= start-page=563 end-page=567 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Backside Irradiation of Ultraviolet-A for Correcting Nonuniformity Error of Gafchromic XR-QA2 Films en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Radiochromic film is used for quality assurance and quality control of X-ray equipment in the diagnostic radiology. In addition, three-dimensional dose distribution of computed tomography (CT) is measured. To correct the nonuniformity and uncertainty of radiochromic films for dose measurement of CT, the films are preirradiated ultraviolet (UV)-A rays. There is a difference in the UV protection strength of radiochromic films. A concern exists about the effects of the UV-A irradiation intensity. We thus irradiated with UV-A rays from the backsides of the films to assess if backside irradiation was possible. Materials and Methods: Gafchromic XR-QA2 and RTQA2 were used in this study. The UV-A rays were simultaneously irradiated on the front and backsides of each film for 12 h. The yellow layer of each film was scanned and imaged. The average pixel values ± standard deviations (SDs) were compared. In the statistical analysis, a paired t-test was performed. To compare, the active-layer densities engendered by the UV-A rays. Calibration curve was created with 48 h of preirradiation of UV-A. Results: The mean pixel values ± SD for Gafchromic XR-QA2 on the front and backsides were 130.776 ± 0.812 and 81.015 ± 1.128, respectively. On the other hand, the mean pixel values ± SD for Gafchromic RTQA2 on the front and backsides were 62.299 ± 1.077 and 133.761 ± 1.365, respectively. The statistical results of the paired t-test were significantly different (P < 0.01) between both films. Fitting equation of the calibration curve is shown below. y = -390.47 ± 200 + (443.45 ± 10x80).5068 ± 0.0434. Conclusion: Based on the relationship between the sensitivity of the active layer to UV-A rays and the strength of UV protection on the surface, we concluded that backside irradiation is recommended for Gafchromic XR-QA2, and frontside irradiation is recommended for Gafchromic RTQA2. en-copyright= kn-copyright= en-aut-name=TankiNobuyoshi en-aut-sei=Tanki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsudaToshizo en-aut-sei=Katsuda en-aut-mei=Toshizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotandaRumi en-aut-sei=Gotanda en-aut-mei=Rumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotandaTatsuhiro en-aut-sei=Gotanda en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwanoTadao en-aut-sei=Kuwano en-aut-mei=Tadao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medical Radiation Technology, Shizuoka College of Medicalcare Science kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=6 en-affil=Department of Radiology, Osaka Center for Cancer and Cardiovascular Diseases Prevention kn-affil= en-keyword=Backside irradiation kn-keyword=Backside irradiation en-keyword=computed tomography kn-keyword=computed tomography en-keyword=reflective type radiochromic film kn-keyword=reflective type radiochromic film en-keyword=ultraviolet radiation kn-keyword=ultraviolet radiation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=51 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoinitiators Induce Histamine Production in Human Mast Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoinitiators are used in the manufacture of many daily products, and may produce harmful effects due to their cytotoxicity. They have also been detected in human serum. Here, we investigated the histamine-producing effects in HMC-1 cells and the inflammatory cytokine release effects in RAW264 cells for four photoinitiators: 1-hydroxycyclohexyl phenyl ketone; 2-isopropylthioxanthone; methyl 2-benzoylbenzoate; and 2-methyl-4´-(methylthio)-2-morpholinopropiophenone. All four promoted histamine production in HMC-1 cells; however, they did not significantly affect the release of inflammatory cytokines in RAW264 cells. These findings suggest that these four photoinitiators induce inflammatory cytokine-independent histamine production, potentially contributing to histamine-mediated chronic inflammation in vitro. en-copyright= kn-copyright= en-aut-name=MiuraTaro en-aut-sei=Miura en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawasakiYoichi en-aut-sei=Kawasaki en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Laboratory of Clinical Pharmacology and Therapeutics, Kagawa School of Pharmaceutical Sciences, Tokushima Bunri University kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photoinitiator kn-keyword=photoinitiator en-keyword=ink kn-keyword=ink en-keyword=injection kn-keyword=injection en-keyword=histamine kn-keyword=histamine en-keyword=inflammation kn-keyword=inflammation END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=35 article-no= start-page=e2320189121 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240821 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Somatic mutations in tumor-infiltrating lymphocytes impact on antitumor immunity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs) exert clinical efficacy against various types of cancers by reinvigorating exhausted CD8+ T cells that can expand and directly attack cancer cells (cancer-specific T cells) among tumor-infiltrating lymphocytes (TILs). Although some reports have identified somatic mutations in TILs, their effect on antitumor immunity remains unclear. In this study, we successfully established 18 cancer-specific T cell clones, which have an exhaustion phenotype, from the TILs of four patients with melanoma. We conducted whole-genome sequencing for these T cell clones and identified various somatic mutations in them with high clonality. Among the somatic mutations, an SH2D2A loss-of-function frameshift mutation and TNFAIP3 deletion could activate T cell effector functions in vitro. Furthermore, we generated CD8+ T cell?specific Tnfaip3 knockout mice and showed that Tnfaip3 function loss in CD8+ T cell increased antitumor immunity, leading to remarkable response to PD-1 blockade in vivo. In addition, we analyzed bulk CD3+ T cells from TILs in additional 12 patients and identified an SH2D2A mutation in one patient through amplicon sequencing.

kn-abstract=Background/Aim: Body weight loss (BWL) after gastrectomy for gastric cancer (GC) decreases postoperative quality of life and survival in patients with GC. This study aimed to evaluate the effect of oral nutritional supplements composed of high protein on BWL in the early period following gastrectomy. Patients and Methods: Pre- and postoperative body weight and skeletal muscle mass were measured using bioelectrical impedance analysis in patients undergoing radical gastrectomy for GC and analyzed retrospectively. Patients received either a regular diet (control group, n=43) or 250 ml (320 kcal) per day of a high-protein oral nutritional supplement (ONS) (22 g protein) in addition to their regular diet (ONS group, n=40) for four weeks after gastrectomy. The actual daily intake of ONS was recorded by patients themselves. The BWL and skeletal muscle loss (SML) at one month after surgery were compared between the two groups. Results: BWL and SML at one month after surgery were similar between the two groups. In the ONS group, patients were divided into two subgroups (ONS-H and ONS-L) according to whether their ONS intake amount was above or below the average value of 216 kcal. The ONS-H group (ONS intake ?216 kcal) showed significantly lower BWL compared to the control group (?4.6±2.6% vs. ?6.2±2.5%; p=0.03). Moreover, the ONS group showed significantly lower BWL at one month after surgery than the control group in cases of total or proximal gastrectomy (?5.9±3.0% vs. ?7.8±1.9%; p=0.04), although no significant difference was observed between the two groups in distal gastrectomy. The hematological nutritional parameters were similar between the two groups. Conclusion: The administration of ONS composed of high protein for four weeks after gastrectomy did not improve BWL at one month after gastrectomy. However, adequate amount of ONS intake and ONS intake after total or proximal gastrectomy might improve BWL. en-copyright= kn-copyright= en-aut-name=KIKUCHISATORU en-aut-sei=KIKUCHI en-aut-mei=SATORU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TAKATANOBUO en-aut-sei=TAKATA en-aut-mei=NOBUO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KAKIUCHIYOSHIHIKO en-aut-sei=KAKIUCHI en-aut-mei=YOSHIHIKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KURODASHINJI en-aut-sei=KURODA en-aut-mei=SHINJI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KASHIMAHAJIME en-aut-sei=KASHIMA en-aut-mei=HAJIME kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TANABESHUNSUKE en-aut-sei=TANABE en-aut-mei=SHUNSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NOMAKAZUHIRO en-aut-sei=NOMA en-aut-mei=KAZUHIRO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TAKAHASHIAYAKO en-aut-sei=TAKAHASHI en-aut-mei=AYAKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KAGAWASHUNSUKE en-aut-sei=KAGAWA en-aut-mei=SHUNSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FUJIWARATOSHIYOSHI en-aut-sei=FUJIWARA en-aut-mei=TOSHIYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Clinical Nutrition, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Amino acid kn-keyword=Amino acid en-keyword=gastrectomy kn-keyword=gastrectomy en-keyword=body weight loss kn-keyword=body weight loss en-keyword=nutritional intervention kn-keyword=nutritional intervention en-keyword=oral nutritional supplements kn-keyword=oral nutritional supplements END start-ver=1.4 cd-journal=joma no-vol=326 cd-vols= no-issue=6 article-no= start-page=F1054 end-page=F1065 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preventive effects of vasohibin-2-targeting peptide vaccine for diabetic nephropathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diabetic nephropathy remains the leading cause of end-stage kidney disease in many countries, and additional therapeutic targets are needed to prevent its development and progression. Some angiogenic factors are involved in the pathogenesis of diabetic nephropathy. Vasohibin-2 (VASH2) is a novel proangiogenic factor, and our previous study showed that glomerular damage is inhibited in diabetic Vash2 homozygous knockout mice. Therefore, we established a VASH2-targeting peptide vaccine as a tool for anti-VASH2 therapy in diabetic nephropathy. In this study, the preventive effects of the VASH2-targeting peptide vaccine against glomerular injury were examined in a streptozotocin (STZ)-induced diabetic mouse model. The mice were subcutaneously injected with the vaccine at two doses 2 wk apart and then intraperitoneally injected with 50 mg/kg STZ for 5 consecutive days. Glomerular injury was evaluated 20 wk after the first vaccination. Treatment with the VASH2-targeting peptide vaccine successfully induced circulating anti-VASH2 antibody without inflammation in major organs. Although the vaccination did not affect blood glucose levels, it significantly prevented hyperglycemia-induced increases in urinary albumin excretion and glomerular volume. The vaccination did not affect increased VASH2 expression but significantly inhibited renal angiopoietin-2 (Angpt2) expression in the diabetic mice. Furthermore, it significantly prevented glomerular macrophage infiltration. The preventive effects of vaccination on glomerular injury were also confirmed in db/db mice. Taken together, the results of this study suggest that the VASH2-targeting peptide vaccine may prevent diabetic glomerular injury in mice by inhibiting Angpt2-mediated microinflammation. en-copyright= kn-copyright= en-aut-name=NakashimaYuri en-aut-sei=Nakashima en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MifuneTomoyo en-aut-sei=Mifune en-aut-mei=Tomoyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakadoiTakato en-aut-sei=Nakadoi en-aut-mei=Takato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayashiHiroki en-aut-sei=Hayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagamiHironori en-aut-sei=Nakagami en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoYasufumi en-aut-sei=Sato en-aut-mei=Yasufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Health Development and Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Health Development and Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=7 en-affil=New Industry Creation Hatchery Center, Tohoku University kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=albuminuria kn-keyword=albuminuria en-keyword=diabetic nephropathy kn-keyword=diabetic nephropathy en-keyword=macrophages kn-keyword=macrophages en-keyword=peptide vaccine kn-keyword=peptide vaccine en-keyword=vasohibin-2 kn-keyword=vasohibin-2 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=29 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Three-Class Annotation Method Improves the AI Detection of Early-Stage Osteosarcoma on Plain Radiographs: A Novel Approach for Rare Cancer Diagnosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Developing high-performance artificial intelligence (AI) models for rare diseases is challenging owing to limited data availability. This study aimed to evaluate whether a novel three-class annotation method for preparing training data could enhance AI model performance in detecting osteosarcoma on plain radiographs compared to conventional single-class annotation. Methods: We developed two annotation methods for the same dataset of 468 osteosarcoma X-rays and 378 normal radiographs: a conventional single-class annotation (1C model) and a novel three-class annotation method (3C model) that separately labeled intramedullary, cortical, and extramedullary tumor components. Both models used identical U-Net-based architectures, differing only in their annotation approaches. Performance was evaluated using an independent validation dataset. Results: Although both models achieved high diagnostic accuracy (AUC: 0.99 vs. 0.98), the 3C model demonstrated superior operational characteristics. At a standardized cutoff value of 0.2, the 3C model maintained balanced performance (sensitivity: 93.28%, specificity: 92.21%), whereas the 1C model showed compromised specificity (83.58%) despite high sensitivity (98.88%). Notably, at the 25th percentile threshold, both models showed identical false-negative rates despite significantly different cutoff values (3C: 0.661 vs. 1C: 0.985), indicating the ability of the 3C model to maintain diagnostic accuracy at substantially lower thresholds. Conclusions: This study demonstrated that anatomically informed three-class annotation can enhance AI model performance for rare disease detection without requiring additional training data. The improved stability at lower thresholds suggests that thoughtful annotation strategies can optimize the AI model training, particularly in contexts where training data are limited. en-copyright=

A comparative study with other non-traumatic etiologies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Vertebral artery dissection (VAD) is a rare cause of non-traumatic subarachnoid hemorrhage (SAH) with significant clinical implications. This study compared the clinical characteristics and outcomes of SAH from intracranial VAD rupture to those from other etiologies, primarily aneurysmal rupture.
Methods: This single-center retrospective cohort study at Okayama University Hospital included patients with non-traumatic SAH diagnosed between 2019 and 2023. Patients were categorized into "VAD rupture" and "other etiologies" groups. The main outcome was clinical presentation and symptoms. Additional outcomes included ICU mortality, in-hospital mortality, and unfavorable outcomes at discharge and 6 months, defined as a modified Rankin Scale score of 3-6.
Results: A total of 66 patients were included, with 14 in the VAD rupture group and 52 in the other etiologies group. The VAD rupture group was younger (median age 49 vs. 64 years, p = 0.003) and had a higher incidence of out-of-hospital cardiac arrest (42.9% vs. 9.6%, p = 0.011). Preceding headache was more common in the VAD rupture group (78.6% vs. 11.5%, p < 0.001), with a median duration of 36 h before presentation. ICU and in-hospital mortality was higher in the VAD rupture group (both 50.0% vs. 19.3%, p = 0.019). No significant differences were found in unfavorable neurological outcomes at hospital discharge and 6 months.
Conclusions: VAD-related SAH often presents with prodromal headaches, severe symptoms like out-of-hospital cardiac arrest, and higher ICU and in-hospital mortality than other SAH causes, though long-term outcomes are similar. Larger, prospective studies are needed to refine interventions. en-copyright= kn-copyright= en-aut-name=OshitaShu en-aut-sei=Oshita en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JinnoShunta en-aut-sei=Jinno en-aut-mei=Shunta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuoIppei en-aut-sei=Matsuo en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=headache kn-keyword=headache en-keyword=intracranial aneurysm kn-keyword=intracranial aneurysm en-keyword=prodromal symptoms kn-keyword=prodromal symptoms en-keyword=subarachnoid hemorrhage kn-keyword=subarachnoid hemorrhage en-keyword=vertebral artery dissection kn-keyword=vertebral artery dissection END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202404400 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Graphene Oxide as a Self‐Carbocatalyst to Facilitate the Ring‐Opening Polymerization of Glycidol for Efficient Polyglycerol Grafting en-subtitle= kn-subtitle= en-abstract= kn-abstract=Grafting carbon-based nanomaterials (CNMs) with polyglycerol (PG) improves their application potentials in biomedicine and electronics. Although “grafting from” method offers advantages over “grafting to” one in terms of operability and versatility, little is known about the reaction process of glycidol with the surface groups onto CNMs. By using graphene oxide (GO) as a multi-functional model material, we examined the reactivity of the surface groups on GO toward glycidol molecules via a set of model reactions. We reveal that carboxyl groups spontaneously react with the epoxide ring with no need of catalyst, while GO catalyzes the reactions of hydroxyl groups with the epoxide of glycidol. In addition, the hydroxyl group of glycidol can open the epoxide in the basal plane of GO. The subsequent polymerization of PG is supposed to propagate at the primary and/or the secondary hydroxyl groups, generating a ramified PG macromolecule with random branch-on-branch topology. In addition, ketones, benzyl esters and aromatic ethers are found not to react with glycidol even in the presence of GO, while the aldehydes are easily oxidized into carboxyl groups under ambient condition, behaving then as the carboxyl groups. Our findings pose the foundation for understanding the polymerization mechanism of PG on CNMs. en-copyright= kn-copyright= en-aut-name=ZouYajuan en-aut-sei=Zou en-aut-mei=Yajuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhkuraKentaro en-aut-sei=Ohkura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Ortiz‐AnayaIsrael en-aut-sei=Ortiz‐Anaya en-aut-mei=Israel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraRyota en-aut-sei=Kimura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Carbon nanomaterials kn-keyword=Carbon nanomaterials en-keyword=Epoxide ring-opening kn-keyword=Epoxide ring-opening en-keyword=Catalysis kn-keyword=Catalysis en-keyword=Polyglycerol functionalization kn-keyword=Polyglycerol functionalization END start-ver=1.4 cd-journal=joma no-vol=222 cd-vols= no-issue= article-no= start-page=115374 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental water in Kolkata is suitable for the survival of Vibrio cholerae O1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many patients with cholera emerge in Kolkata, India throughout the year. Such emergency indicates that cholera toxin-producing Vibrio cholerae O1 (toxigenic V. cholerae O1) are widespread in Kolkata. This suggests that the suitable conditions for replication of toxigenic V. cholerae O1 is provided in Kolkata. In previous studies, we found that the replication rate of toxigenic V. cholerae O1 is low in the low ionic aqueous solution. Then we measured the ion concentration in the environmental water of Kolkata. As a control, we measured them in Japanese environmental water. The ion concentration in the environmental water of Kolkata was significantly high. Then, we examined the survival of toxigenic V. cholerae O1 in groundwater from Kolkata and found that V. cholerae O1 survive for long time in the solution but not in the solution diluted with Milli Q water. In addition, we found that V. cholerae O1 proliferated in environmental water of Kolkata to which a small amount of nutrient was added, but did not grow in the environmental water diluted with water to which the same amount of nutrient was added. These results indicate that the environmental water from Kolkata is suitable for survival of V. cholerae O1. en-copyright= kn-copyright= en-aut-name=TakahashiEizo en-aut-sei=Takahashi en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchiSadayuki en-aut-sei=Ochi en-aut-mei=Sadayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=2 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= affil-num=4 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=5 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=6 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=Department of Health Pharmacy, Yokohama University of Pharmacy kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= en-keyword=Environmental water kn-keyword=Environmental water en-keyword=Ion kn-keyword=Ion en-keyword=Prevalence kn-keyword=Prevalence en-keyword=Survival kn-keyword=Survival en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=2 article-no= start-page=102575 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical and microbiological characteristics of high-level daptomycin-resistant Corynebacterium species: A systematic scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Corynebacterium species potentially develop high-level daptomycin resistance (HLDR) shortly after daptomycin (DAP) administration. We aimed to investigate the clinical and microbiological characteristics of HLDR Corynebacterium infections.
Methods: We first presented a clinical case accompanied by the results of a comprehensive genetic analysis of the isolate, and then performed a systematic scoping review. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews, we searched for articles with related keywords, including “Corynebacterium”, “Daptomycin", and "Resistance”, in the MEDLINE and Web of Science databases from the database inception to October 25, 2024. Clinical case reports and research articles documenting the isolation of HLDR Corynebacterium species, defined by a minimum inhibitory concentration of DAP at ?256 μg/mL, were deemed eligible for this review.
Results: Of 80 articles screened, seven case reports detailing eight cases of HLDR Corynebacterium infections, as well as five research articles, were included. C. striatum was the most common species (7/9 cases, 77.8 %), and prosthetic device-associated infections accounted for 66.7 % of the cases. Duration of DAP administration before the emergence of HLDR isolates ranged from 5 days to 3 months; three-quarters of the cases developed within 17 days. Three HLDR isolates were genetically confirmed to have an alteration in pgsA2. The majority of the patients were treated with either glycopeptides or linezolid, with favorable outcomes. In vitro experiments confirmed that C. striatum strains acquire the HLDR phenotype at higher rates (71 %?100 %) within 24 h of incubation, compared to other Corynebacterium strains.
Conclusion: DAP monotherapy, especially for prosthetic device-associated infections, can result in the development of HLDR Corynebacterium. Additional research is warranted to investigate the clinical implications of this potentially proliferating antimicrobial resistant pathogen. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=Corynebacterium kn-keyword=Corynebacterium en-keyword=Daptomycin kn-keyword=Daptomycin en-keyword=High-level daptomycin resistance kn-keyword=High-level daptomycin resistance en-keyword=pgsA2 kn-keyword=pgsA2 END start-ver=1.4 cd-journal=joma no-vol=391 cd-vols= no-issue= article-no= start-page=158 end-page=176 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Magnesium isotope composition of volcanic rocks from cold and warm subduction zones: Implications for the recycling of subducted serpentinites and carbonates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Magnesium (Mg) isotopes are regarded as a sensitive tracer to the contribution from subducted serpentinites and carbonates. However, the source, distribution, and controlling factors of the Mg isotope composition of arc magmas remain unclear. In this study, we investigated the intra-arc and inter-arc variations in Mg isotope compositions of volcanic rocks from two typical cold subduction zones [NE Japan (NEJ) and Izu arcs] and a typical hot subduction zone [SW Japan (SWJ) arc] to address the question. The volcanic rocks from the frontal-arc regions of NEJ and Izu have isotopically heavy Mg (δ26Mg = ?0.20 to ?0.08 ‰) compared to the mantle-like δ26Mg values of most of volcanic rocks from SWJ and the rear regions of NEJ and Izu arcs (?0.28 to ?0.17 ‰). It is also worth noting that NEJ arc includes samples with δ26Mg values (?0.61 to ?0.39 ‰) significantly lower than the mantle, but similar to the < 110 Ma intra-continental basalts from eastern China, which is the first observation in modern arc rocks. No obvious effects of post-eruptive alteration, fractional crystallization, partial melting, or the addition of silicate-rich sediment and oceanic crust components could be identified in the Mg isotope compositions of these volcanic rocks. By contrast, the correlations between the δ26Mg values and the proxy for serpentinite component (i.e., 11B/10B and Nb/B ratios) indicate that the component exerts a strong control on the Mg-isotopic signature of these arc rocks. Considering metamorphic reactions in subduction lithologies under P-T conditions postulated for these arcs, the variations in δ26Mg values of these arc magmas are unlikely to have been controlled by dehydration of serpentinites in subducted oceanic lithosphere (slab serpentinite). Instead, the high-δ26Mg values of frontal-arc rocks are delivered by the fluids from serpentinite formed in the lowermost part of the sub-arc mantle (mantle wedge serpentinite) in channelized flow. Comparatively, such a high-δ26Mg signature is invisible in volcanic rocks from rear-arc regions of NEJ and Izu, and the entire SWJ, suggesting that the major Mg carriers in subducted serpentinites (e.g., talc, chlorite, and serpentine) were broken down completely before subducted slabs reached the depth beneath these volcanoes. Moreover, the volcanic rocks with low δ26Mg values from the rear arc of NEJ are characterized by high La/Yb and U/Nb ratios as well as low Ti/Eu, Ti/Ti*, and Hf/Hf* ratios, suggesting the involvements of carbonates in their magma sources. The quantitative modeling suggests that < 20 % of sedimentary carbonate (dolomite) was recycled into their mantle source, revealing that Mg-rich carbonate could be incorporated into a deep mantle wedge at rear-arc depths of 150?400 km in subduction zones. en-copyright= kn-copyright= en-aut-name=ZhangWei en-aut-sei=Zhang en-aut-mei=Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitagawaHiroshi en-aut-sei=Kitagawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HuangFang en-aut-sei=Huang en-aut-mei=Fang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=CAS Key Laboratory of Crust-Mantle Materials and Environments, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= en-keyword=Magnesium isotopes kn-keyword=Magnesium isotopes en-keyword=Arc magmas kn-keyword=Arc magmas en-keyword=Mantle wedge serpentinite kn-keyword=Mantle wedge serpentinite en-keyword=Slab serpentinite kn-keyword=Slab serpentinite en-keyword=Carbonate recycle kn-keyword=Carbonate recycle END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue= article-no= start-page=105534 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Currency portfolios and global foreign exchange ambiguity en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates whether cross-sectional global foreign exchange (FX) ambiguity impacts currency portfolios. We observe that, in contrast to FX volatility, high FX ambiguity leads to high currency carry returns. We also reveal that FX ambiguity is weakly associated with the highest interest rate portfolio, but strongly related to the second highest interest rate portfolio. These results suggest that FX ambiguity captures elements of uncertainty that are not captured by FX volatility. In addition, FX ambiguity is not linked to returns on currency momentum and value portfolios. en-copyright= kn-copyright= en-aut-name=AsanoTakao en-aut-sei=Asano en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CaiXiaojing en-aut-sei=Cai en-aut-mei=Xiaojing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakemotoRyuta en-aut-sei=Sakemoto en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Economics, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Economics, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Economics and Business, Hokkaido University kn-affil= en-keyword=Currency portfolio kn-keyword=Currency portfolio en-keyword=Ambiguity kn-keyword=Ambiguity en-keyword=Carry trades kn-keyword=Carry trades en-keyword=FX volatility kn-keyword=FX volatility END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=48 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of oral health care intervention for stroke patients following the introduction of Oral Health Assessment Tool en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: This study aimed to evaluate the effectiveness of oral health assessment tools in facilitating oral health care interventions by dental care providers for acute stroke patients within 48?h of admission, following a reform of the nursing system.
Methods: Data were gathered from a retrospective cohort study conducted at a stroke center, comparing 10?months before and after the implementation of the reformed system, with a 2-month interval. Parameters assessed included stroke type, severity measured using the National Institutes of Health Stroke Scale, stroke history, stroke-related factors, number of teeth, hospitalization cost and duration, occurrence of fever and pneumonia, stroke treatment, days from admission to dental intervention, and intervention frequency.
Results: Implementation of the new system significantly reduced the time before dental intervention (P? Conclusions: Although the frequency and duration of fevers increased slightly, this approach, incorporating oral health assessment tools, made it possible to provide early dental intervention, particularly for patients with severe strokes.

We compared the outcomes of each method for the appropriate choice. Methods: Patients who underwent CSP, endoscopic mucosal resection (EMR)/hot snare polypectomy (HSP), or UEMR for small and intermediate-sized colorectal polyps between April 2017 and June 2020 were retrospectively examined. The rate of adverse events and recurrences due to each method were determined as the main outcomes. Clinical factors related to adverse events were examined. Results: A total of 1,025 patients with 3,163 polyps underwent polypectomy using any of the methods. CSP, EMR/HSP, and UEMR were performed for 704 (22.2%), 2,145 (67.8%), and 314 polyps (9.9%), and the median size for each method was 4, 6, and 7 mm, respectively. Delayed bleeding for CSP, EMR/HSP, and UEMR was 0%, 0.2%, and 0.6% (p = 0.15), and perforation was 0%, 0.1%, and 0%, respectively (p = 0.62). Recurrence after CSP, EMR/HSP, and UEMR was 0.3%, 0.09%, and 1.3%, respectively (p < 0.01). Recurrence for UEMR was significantly higher in the early stage of procedure introduction (p = 0.015). Oral anticoagulants were the risk factor for delayed bleeding (p < 0.01, respectively). Conclusion: There was no significant difference regarding adverse events among each method for small and intermediate-sized polyps, although the recurrence rate after UEMR was higher than other methods. en-copyright= kn-copyright= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeiKensuke en-aut-sei=Takei en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= en-keyword=Underwater endoscopic mucosal resection kn-keyword=Underwater endoscopic mucosal resection en-keyword=Endoscopic mucosal resection kn-keyword=Endoscopic mucosal resection en-keyword=Cold snare polypectomy kn-keyword=Cold snare polypectomy END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=11 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mutation and apoptosis are well-coordinated for protecting against DNA damage-inducing toxicity in Drosophila en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Apoptotic cell death is an important survival system for multicellular organisms because it removes damaged cells. Mutation is also a survival method for dealing with damaged cells in multicellular and also unicellular organisms, when DNA lesions are not removed. However, to the best of our knowledge, no reports have comprehensively explored the direct relationship between apoptosis and somatic cell mutations induced by various mutagenic factors.
Results Mutation was examined by the wing-spot test, which is used to detect somatic cell mutations, including chromosomal recombination. Apoptosis was observed in the wing discs by acridine orange staining in situ. After treatment with chemical mutagens, ultraviolet light (UV), and X-ray, both the apoptotic frequency and mutagenic activity increased in a dose-dependent manner at non-toxic doses. When we used DNA repair-deficient Drosophila strains, the correlation coefficient of the relationship between apoptosis and mutagenicity, differed from that of the wild-type. To explore how apoptosis affects the behavior of mutated cells, we determined the spot size, i.e., the number of mutated cells in a spot. In parallel with an increase in apoptosis, the spot size increased with MNU or X-ray treatment dose-dependently; however, this increase was not seen with UV irradiation. In addition, BrdU incorporation, an indicator of cell proliferation, in the wing discs was suppressed at 6 h, with peak at 12 h post-treatment with X-ray, and that it started to increase again at 24 h; however, this was not seen with UV irradiation.
Conclusion Damage-induced apoptosis and mutation might be coordinated with each other, and the frequency of apoptosis and mutagenicity are balanced depending on the type of DNA damage. From the data of the spot size and BrdU incorporation, it is possible that mutated cells replace apoptotic cells due to their high frequency of cell division, resulting in enlargement of the spot size after MNU or X-ray treatment. We consider that the induction of mutation, apoptosis, and/or cell growth varies in multi-cellular organisms depending on the type of the mutagens, and that their balance and coordination have an important function to counter DNA damage for the survival of the organism. en-copyright= kn-copyright= en-aut-name=Toyoshima-SasataniMegumi en-aut-sei=Toyoshima-Sasatani en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImuraFumika en-aut-sei=Imura en-aut-mei=Fumika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamatakeYuko en-aut-sei=Hamatake en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukunagaAkihiro en-aut-sei=Fukunaga en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NegishiTomoe en-aut-sei=Negishi en-aut-mei=Tomoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=School of Nursing, Osaka City University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Drosophila kn-keyword=Drosophila en-keyword=Apoptosis kn-keyword=Apoptosis en-keyword=Mutation kn-keyword=Mutation en-keyword=Larval wing disc kn-keyword=Larval wing disc en-keyword=X-ray kn-keyword=X-ray en-keyword=Ultraviolet kn-keyword=Ultraviolet en-keyword=Alkylating agents kn-keyword=Alkylating agents en-keyword=Tobacco smoke kn-keyword=Tobacco smoke en-keyword=Acridine orange kn-keyword=Acridine orange en-keyword=BrdU kn-keyword=BrdU END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=4 article-no= start-page=213 end-page=218 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=β-catenin Binds to Gsk-3β in Liquid-Liquid Phase Separation Compartment in HEK293 Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liquid-liquid phase separation (LLPS) has emerged as a significant mechanism for cellular organization, impacting various biological processes, including Wnt/β-catenin signaling. This study investigates the role of LLPS in the regulation of β-catenin in HEK293 cells, particularly in response to Wnt3a signaling. Our findings demonstrate that β-catenin is regulated by LLPS, forming spherical droplets indicative of this phenomenon. Fluorescence recovery after photobleaching (FRAP) assays revealed that these droplets exhibit reversible dynamics, further confirming their phase-separated nature. Importantly, treatment with Wnt3a led to an increase in β-catenin levels, while simultaneously reducing the recovery of fluorescence intensity in FRAP experiments, suggesting that enhanced Wnt signaling may stimulate the release of β-catenin from LLPS. Immunoprecipitation studies indicated that β-catenin binds to glycogen synthase kinase 3β (Gsk-3β) within the LLPS state, highlighting a potential regulatory mechanism whereby LLPS facilitates the phosphorylation and subsequent degradation of β-catenin. The addition of 1,6-hexanediol disrupted the β-catenin/Gsk-3β interaction, reinforcing the idea that LLPS plays a critical role in modulating these biochemical interactions. The findings presented in this study suggest that LLPS is not only crucial for the spatial organization of β-catenin but also serves as a regulatory mechanism for its signaling functions in the Wnt pathway. Given the association of aberrant Wnt signaling with various diseases, including cancer and neurodegenerative disorders, understanding the role of LLPS in this context may provide new insights into therapeutic strategies targeting these pathological conditions. en-copyright= kn-copyright= en-aut-name=KatoMari en-aut-sei=Kato en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanaiAiri en-aut-sei=Tanai en-aut-mei=Airi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuharaYoko en-aut-sei=Fukuhara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhengXinyu en-aut-sei=Zheng en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SitosariHeriati en-aut-sei=Sitosari en-aut-mei=Heriati kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IkegameMika en-aut-sei=Ikegame en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamuraHirohiko en-aut-sei=Okamura en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=β-catenin kn-keyword=β-catenin en-keyword=Gsk-3β kn-keyword=Gsk-3β en-keyword=LLPS kn-keyword=LLPS en-keyword=Wnt kn-keyword=Wnt END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of aged microplastics on paddy soil properties and greenhouse gas emissions under laboratory aerobic conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microplastics (MPs) formed after changes in chemical or physical properties may alter soil properties, which in turn may affect microbial activities and greenhouse gas (GHG) emissions. However, few studies have focused on the effects of aged MPs changes on soil properties and greenhouse gas emissions. Therefore, we aimed to investigate the impact of MPs with different aging times on soil GHG emissions and dissolved organic carbon (DOC). Low-density polyethylene (PE) and polylactic acid (PLA) were treated with ultraviolet (UV) irradiation for 0?2?weeks. Soil was incubated with PE or PLA 1% (w/w) concentration at 60% water holding capacity (WHC) for 35?days. Emissions of nitrous oxide (N2O) and carbon dioxide (CO2) were measured on days 0, 1, 3, 5, 7, 14, 21, 28, and 35. Results showed that CO2 and N2O emissions were higher (p? Methods: Participants were 45,233 older adults aged 75 and over living in Kure City, Japan. In addition to the government-mandated health checkup items, the Intervention group underwent additional risk screening tests included questionnaires, physical examinations, blood tests, and educational guidance by nurses. The efficacy of the intervention was examined whether there were differences in the number of hospitalizations, the use of emergency and critical care, and the incidence of hemodialysis induction between the Intervention and control groups (Usual Health Checkup group and No Health Checkup group) for the 2 years.
Results: There were 485 participants in the Intervention group, 1,067 in the Usual Health Checkup group, and 43,712 in the No Health Checkup group. As the risks of seven diseases in the Intervention group, the largest proportion of deviations occurred for systolic blood pressure (63.3%), estimated salt intake (60.3%), and low-density lipoprotein cholesterol (51.5%). Estimated glomerular filtration rate deviated in 41.0%, N-terminal pro b-type natriuretic peptide in 37.9%. 7.5% scored <2 points on the Mini-Cog (c), and 9.1% performed the Timed Up and Go test in >12 s. The incidence of hospitalization due to any of the seven diseases was significantly higher in the No Health Checkup group (p < 0.001). There were no differences among the three groups in the use of emergency and critical care or the introduction of hemodialysis.
Conclusion: This study revealed that additional health checkup tests and intervention methods could be prevented hospitalization among the adults of 75 years and older. It is necessary to make health checkups and follow-ups more accessible those are already available within the existing health system in Japan. en-copyright= kn-copyright= en-aut-name=KazawaKana en-aut-sei=Kazawa en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiMadoka en-aut-sei=Kawai en-aut-mei=Madoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyamaMichiko en-aut-sei=Moriyama en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Nursing Science, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=3 en-affil=Division of Nursing Science, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= en-keyword=older adults kn-keyword=older adults en-keyword=health checkups kn-keyword=health checkups en-keyword=health risk kn-keyword=health risk en-keyword=hospitalization kn-keyword=hospitalization en-keyword=education kn-keyword=education END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1251 end-page=1273 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Skewing Technology for Permanent Magnet Synchronous Motors: A Comprehensive Review and Recent Trends en-subtitle= kn-subtitle= en-abstract= kn-abstract=This article gives a comprehensive overview of the current research trends in the skewing technique for permanent magnet synchronous motors (PMSMs). The skewing technique has been widely used in many applications to reduce the cogging torque and torque ripple in PMSMs. There are many ways to implement the skew, and new techniques are continually being developed. First, this article summarizes the types of skew structures and presents a survey of existing techniques. Specific emphasis is placed on what kind of skew structure is selected depending on the PMSM configuration. Second, the optimal value of the skew angle for each structure is comprehensively explained, and the discrepancy between theory and finite element analysis is discussed. The definition of skew angle varies across the literature, and one of the purposes of this article is to organize the definition in an easy-to-understand manner. In addition, this article offers three-dimensional finite element analysis (3D-FEA) results of various PMSMs employing the skew for quantitative comparison. Then, this article discusses the properties of PMSMs using the skew by structure and the latest trends, and finally describes future prospects. en-copyright= kn-copyright= en-aut-name=TsunataRen en-aut-sei=Tsunata en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoMasatsugu en-aut-sei=Takemoto en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Additive manufacturing (AM) kn-keyword=Additive manufacturing (AM) en-keyword=axial leakage flux kn-keyword=axial leakage flux en-keyword=cogging torque kn-keyword=cogging torque en-keyword=electrical machine kn-keyword=electrical machine en-keyword=finite element analysis (FEA) kn-keyword=finite element analysis (FEA) en-keyword=induction motor (IM) kn-keyword=induction motor (IM) en-keyword=interior permanent magnet synchronous motor (IPMSM) kn-keyword=interior permanent magnet synchronous motor (IPMSM) en-keyword=noise kn-keyword=noise en-keyword=patents kn-keyword=patents en-keyword=permanent magnet synchronous motor (PMSM) kn-keyword=permanent magnet synchronous motor (PMSM) en-keyword=skew kn-keyword=skew en-keyword=surface permanent magnet synchronous motor (SPMSM) kn-keyword=surface permanent magnet synchronous motor (SPMSM) en-keyword=torque ripple kn-keyword=torque ripple en-keyword=total harmonic distortion (THD) kn-keyword=total harmonic distortion (THD) en-keyword=traction motor kn-keyword=traction motor en-keyword=transportation kn-keyword=transportation en-keyword=vibration kn-keyword=vibration END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=2 article-no= start-page=292 end-page=305 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The role of C1orf50 in breast cancer progression and prognosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the prognosis of breast cancer has significantly improved compared to other types of cancer, there are still some patients who expire due to recurrence or metastasis. Therefore, it is necessary to develop a method to identify patients with poor prognosis at the early stages of cancer. In the process of discovering new prognostic markers from genes of unknown function, we found that the expression of C1orf50 determines the prognosis of breast cancer patients, especially for those with Luminal A breast cancer. This study aims to elucidate the molecular role of C1orf50 in breast cancer progression. Bioinformatic analyses of the breast cancer dataset of TCGA, and in vitro analyses, reveal the molecular pathways influenced by C1orf50 expression. C1orf50 knockdown suppressed the cell cycle of breast cancer cells and weakened their ability to maintain the undifferentiated state and self-renewal capacity. Interestingly, upregulation of C1orf50 increased sensitivity to CDK4/6 inhibition. In addition, C1orf50 was found to be more abundant in breast cancer cells than in normal breast epithelium, suggesting C1orf50’s involvement in breast cancer pathogenesis. Furthermore, the mRNA expression level of C1orf50 was positively correlated with the expression of PD-L1 and its related factors. These results suggest that C1orf50 promotes breast cancer progression through cell cycle upregulation, maintenance of cancer stemness, and immune evasion mechanisms. Our study uncovers the biological functions of C1orf50 in Luminal breast cancer progression, a finding not previously reported in any type of cancer. en-copyright= kn-copyright= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAtsushi en-aut-sei=Tanaka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaekawaMasaki en-aut-sei=Maekawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Pe?aTirso en-aut-sei=Pe?a en-aut-mei=Tirso kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RogachevskayaAnna en-aut-sei=Rogachevskaya en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndoTeruhiko en-aut-sei=Ando en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=RoehrlMichael H. en-aut-sei=Roehrl en-aut-mei=Michael H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=2 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=3 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=5 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=13 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=14 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=Luminal A breast cancer kn-keyword=Luminal A breast cancer en-keyword=Cell cycle kn-keyword=Cell cycle en-keyword=Immune evasion kn-keyword=Immune evasion en-keyword=YAP/TAZ kn-keyword=YAP/TAZ END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=60 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful immunotherapy with ipilimumab and nivolumab in a patient with pulmonary sclerosing pneumocytoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulmonary sclerosing pneumocytoma (PSP) is a rare form of lung cancer that occasionally presents with lymph node and extrapulmonary metastases, and multiple lesions. The treatment of metastatic PSP remains undefined. This study reports the case of a 48-year-old female patient diagnosed with PSP following surgical intervention for a solitary nodule in the left lower lobe. Four years later, recurrence occurred in the left hilar and mediastinal lymph nodes, necessitating an additional resection. Concurrently, sacral metastases developed and required palliative radiotherapy. Genetic analysis identified an AKT1 E17K mutation, characteristic of PSP, and absence of programmed cell death ligand 1 (PD-L1) expression in the tumor. Two years post-recurrence, the tumor recurred in the left mammary gland and mediastinal lymph nodes. Combination immunotherapy with ipilimumab and nivolumab yielded a significantly positive response in this metastatic PSP case. This is the first reported case of successful treatment of multiple distant metastatic PSP with ipilimumab and nivolumab, following the failure of various local treatments. Further case series are warranted to validate the efficacy of immunotherapy in metastatic PSP. en-copyright= kn-copyright= en-aut-name=Inukai-MotokuraYumi en-aut-sei=Inukai-Motokura en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BabaTakahiro en-aut-sei=Baba en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmoriHiroki en-aut-sei=Omori en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeguchiTetsuya en-aut-sei=Takeguchi en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UnoMari en-aut-sei=Uno en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AyadaYoshiyuki en-aut-sei=Ayada en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathology and Oncology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=Pulmonary sclerosing pneumocytoma kn-keyword=Pulmonary sclerosing pneumocytoma en-keyword=Ipilimumab kn-keyword=Ipilimumab en-keyword=Nivolumab kn-keyword=Nivolumab en-keyword=Programmed cell death ligand 1 kn-keyword=Programmed cell death ligand 1 en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=22 article-no= start-page=7382 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microdetection of Nucleocapsid Proteins via Terahertz Chemical Microscope Using Aptamers en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), several methods have been employed, including the detection of viral ribonucleic acid (RNA), nucleocapsid (N) proteins, spike proteins, and antibodies. RNA detection, primarily through polymerase chain reaction tests, targets the viral genetic material, whereas antigen tests detect N and spike proteins to identify active infections. In addition, antibody tests are performed to measure the immune response, indicating previous exposure or vaccination. Here, we used the developed terahertz chemical microscope (TCM) to detect different concentrations of N protein in solution by immobilizing aptamers on a semiconductor substrate (sensing plate) and demonstrated that the terahertz amplitude varies as the concentration of N proteins increases, exhibiting a highly linear relationship with a coefficient of determination (R2 = 0.9881), indicating that a quantitative measurement of N proteins is achieved. By optimizing the reaction conditions, we confirmed that the amplitude of the terahertz wave was independent of the solution volume. Consequently, trace amounts (0.5 μL) of the N protein were successfully detected, and the detection process only took 10 min. Therefore, this study is expected to develop a rapid and sensitive method for the detection and observation of the SARS-CoV-2 virus at a microdetection level. It is anticipated that this research will significantly contribute to reducing the spread of novel infectious diseases in the future. en-copyright= kn-copyright= en-aut-name=DingXue en-aut-sei=Ding en-aut-mei=Xue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiMana en-aut-sei=Murakami en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University Hospital kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=terahertz chemical microscope kn-keyword=terahertz chemical microscope en-keyword=aptamers kn-keyword=aptamers en-keyword=N protein kn-keyword=N protein en-keyword=microdetection kn-keyword=microdetection END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=4 article-no= start-page=463 end-page=469 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of the Original COVID-19 Vaccine against COVID-19 Exacerbations during the Omicron Wave: A Population-based Study in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: In Japan, approximately 97 million individuals have received their primary two doses of coronavirus disease 2019 (COVID-19) vaccine at the end of 2022. In this study, we aim to examine the effectiveness of the primary vaccines and compare its efficacy to booster vaccine shots in terms of preventing COVID-19 exacerbations during the Omicron-predominant period in Japan.
Methods: For this analysis, we have collected all the confirmed COVID-19-positive cases from different medical institutions in Okayama City and have also utilized the information from the public Vaccination Record System. Taking the number of vaccinations into consideration, we then conducted a population-based study to assess the effectiveness of the two primary vaccine doses in preventing COVID-19 exacerbations during the Omicron waves. Our primary and secondary outcomes were COVID-19 exacerbations with respiratory failure (i.e., oxygen saturation on room air ? 93%, requiring supplemental oxygen), intensive care unit admission and/or mechanical ventilator requirement, or death, in accordance with the Japanese COVID-19 guidelines, and pneumonia during the course of COVID-19 infection, respectively.
Results: In total, 95,329 COVID-19-positive individuals, aged 5 years and above, were included in this analysis (study period from January 1 to September 10, 2022). As per our findings, the effectiveness of the primary two doses against COVID-19 exacerbations compared with those who had never been vaccinated was 55.5% (95% confidential interval [CI]: 32.6-71.7), whereas it was higher after the third dose (76.9%; 95% CI: 66.7-84.0) and the fourth dose (75.7%; 95% CI: 58.8-85.7). Effectiveness was sustained for ? 5 months after the third vaccination, and preventive effectiveness was observed in individuals aged ? 65 years.
Conclusions: As per the results of this study, we can conclude that the efficacy of the primary two doses of SARS-CoV-2 vaccine can be further strengthened in terms of preventing COVID-19 exacerbations by administering third and fourth booster vaccine shots. The additional bivalent vaccine is anticipated to further increase its efficacy against the Omicron strain, suggesting that individuals who have not received their booster shots yet should consider getting them to prevent COVID-19 exacerbations. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuoRumi en-aut-sei=Matsuo en-aut-mei=Rumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=Vaccine kn-keyword=Vaccine en-keyword=Omicron kn-keyword=Omicron en-keyword=Prevention kn-keyword=Prevention en-keyword=Pneumonia kn-keyword=Pneumonia END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=10 article-no= start-page=1488 end-page=1500 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Method for Inter-Broadcaster Data Integration of Non-Identifiable Television Viewing Log kn-title=非特定テレビ視聴履歴データの放送局間統合手法 en-subtitle= kn-subtitle= en-abstract=Recently, TV broadcasters have been collecting and utilizing non-personal TV viewing log data, including start and end times of viewing, from TVs connected to the Internet in a format that does not identify individual viewers. However, since each broadcaster can only use its own non-personal TV viewing log data, it has not yet been able to obtain useful knowledge despite the vast amount of data it has accumulated. In addition, the collection methods and data granularity of non-personal TV viewing log data vary from station to station, and the data accumulated by each station cannot be integrated and used. In this paper, we propose a method for matching non-specific viewing history data collected by each broadcaster using its own method, and design and implement a simulator to evaluate the proposed method. The proposed method estimates that TVs whose channel transition timing matches five items collected at the time of viewing history data collection (IP address, zip code, manufacturer ID, browser major version, and browser minor version) are the same TVs. In addition, we designed a simulator that reproduces viewer behavior and applied this method to the viewing history data synthesized from the simulator. As a result, we succeeded in matching approximately 2.41 million TVs out of the 2.5 million units of data generated, showing an identification rate of 96.5%. kn-abstract=近年,各テレビ放送局において,個人を特定しない形式で,インターネット接続されたテレビから視聴開始時刻や視聴終了時刻等を含む非特定視聴履歴データを収集し,利活用する取り組みが進められている.しかし,各放送局は自局の非特定視聴履歴データしか利用できないため,膨大なデータを蓄積しているにもかかわらず,有用な知見を得るまでに至っていないのが現状である.さらに,非特定視聴履歴データの収集方式やデータ粒度は,各局各様となっており,各局が蓄積したデータを統合し,利用することもできていない.そこで本論文では,各局が独自の方式で取得している非特定視聴履歴データを放送局間で統合する手法を提案し,評価するためのシミュレータ設計と実装を行い,提案手法の評価を行う.

Subsequently, next-generation sequencing (NGS) yielded a positive BRD4-NUTM1 fusion. In addition, positive NUT immunostaining of the lung biopsy specimen confirmed NUTC in the lungs. Systemic chemotherapy and radiotherapy showed a temporary response, with decreased serum alpha-fetoprotein levels.

The cross-linking density of inner microparticles is found to be strongly correlated to not only several properties of individual microparticles, such as swelling ratio and radius of gyration, but also the tinter and toughness of the corresponding films. Therefore, the tinter and toughness values follow a linear relationship because the cross-linking restricts the mixing of polymer chains between their surfaces in the film, which is a unique feature of microparticle-based films. This characteristic also affects their deformation behavior observed by in situ SAXS during tensile testing and their density profiles calculated by AA-MD simulations. This work provides a general strategy for material design to control the physical properties and structures of their films for advanced applications, including volatile organic compound-free sustainable coatings and adhesives. en-copyright= kn-copyright= en-aut-name=NambaKeita en-aut-sei=Namba en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiYuma en-aut-sei=Sasaki en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawamuraYuto en-aut-sei=Kawamura en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaShotaro en-aut-sei=Yoshida en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiedaYoshiki en-aut-sei=Hieda en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoKazushi en-aut-sei=Fujimoto en-aut-mei=Kazushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeNatsuki en-aut-sei=Watanabe en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishizawaYuichiro en-aut-sei=Nishizawa en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchihashiTakayuki en-aut-sei=Uchihashi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuzukiDaisuke en-aut-sei=Suzuki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KurehaTakuma en-aut-sei=Kureha en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Frontier Materials Chemistry, Graduate School of Science and Technology, Hirosaki University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Textile Science &Technology, Shinshu University kn-affil= affil-num=4 en-affil=Department of Materials Chemistry, Nagoya University kn-affil= affil-num=5 en-affil=Department of Chemistry and Materials Engineering, Faculty of Chemistry, Materials and Bioengineering, Kansai University kn-affil= affil-num=6 en-affil=Department of Chemistry and Materials Engineering, Faculty of Chemistry, Materials and Bioengineering, Kansai University kn-affil= affil-num=7 en-affil=Department of Physics, Nagoya University kn-affil= affil-num=8 en-affil=Department of Physics, Nagoya University kn-affil= affil-num=9 en-affil=Department of Physics, Nagoya University kn-affil= affil-num=10 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Department of Frontier Materials Chemistry, Graduate School of Science and Technology, Hirosaki University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=1 article-no= start-page=131 end-page=142 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-World Comparative Analysis of Trastuzumab Originator and Biosimilars: Safety, Efficacy, and Cost Effectiveness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Despite the global use of trastuzumab biosimilars, concerns remain regarding their efficacy and safety. In particular, when used concurrently with pertuzumab, trastuzumab biosimilars lack extensive real-world data and safety information. Additionally, as cancer drug expenditures continue to rise worldwide, cost savings from biosimilars have become increasingly important.
Objective This study aims to assess the safety, efficacy, and cost effectiveness of trastuzumab originators and their biosimilars in real-world clinical settings, focusing on a large patient population.
Methods The analysis included 31,661 patients with HER2-positive breast cancer from the Medical Data Vision Co., Ltd. database in Japan. Additionally, adverse event reports for the trastuzumab originator and its biosimilars were obtained for 58,799 patients from the World Health Organization’s VigiBase, the global adverse event reporting database.
Results No significant differences were observed in heart failure hospitalizations, liver dysfunction, or infusion reaction rates in both the Medical Data Vision Co., Ltd. database and the World Health Organization’s VigiBase. In the Medical Data Vision Co., Ltd. database, the addition of pertuzumab did not significantly influence the incidence of adverse events, and the use of biosimilars significantly reduced medical costs, with no significant difference in breast cancer recurrence rates.
Conclusions By analyzing two large and diverse datasets from multiple perspectives, we obtained reliable results that the trastuzumab originator and its biosimilars have similar safety profiles. The concurrent use of pertuzumab was also found to be safe. The use of biosimilars can lead to cost savings. These findings provide crucial insights for the evaluation and adoption of biosimilars in clinical practice. en-copyright= kn-copyright= en-aut-name=MamoriTomoka en-aut-sei=Mamori en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniokaMaki en-aut-sei=Tanioka en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakadaKenji en-aut-sei=Takada en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwataniTsuguo en-aut-sei=Iwatani en-aut-mei=Tsuguo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Medical AI Project, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=142592 end-page=142605 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=MUSIC Spectrum Based Interference Detection, Localization, and Interference Arrival Prediction for mmWave IRS-MIMO System en-subtitle= kn-subtitle= en-abstract= kn-abstract=For a millimeter wave (mmWave) intelligent re-configurable surface (IRS)-MIMO system, if it can correctly detect the interference occurrence and their locations, the patterns of interference signal can be collected and learned using machine learning for the prediction of interference arrival. With the information of interference location and activity pattern, the capacity of the system can be largely improved using many techniques such as beamforming, interference cancellation, and transmission scheduling. This paper aims to detect interference occurrence using a low-complexity MUSIC (MUSIC: multiple signal classification) spectrum-based method, and then localize their sources for mmWave IRS-MIMO system. The MUSIC spectrum of wireless system can be regarded as somehow the 'signature' related to the signals transmitted from different users or interference. We utilize such property to detect the occurrence of interference, and then localize their sources in a low-complexity way. Finally, the pattern of interference occurrence can be learned to predict the interference arrival from the collected data. This paper also proposed an efficient probabilistic neural network (PNN)-based predictor for the interference arrival prediction and showed its prediction accuracy. From simulated results, our proposed method can achieve the correct results with the accuracy near to 100% when the fingerprint samples is over 10. In addition, the localization error can be within 1 m with more than 65% and 43% for Y-axis and X-axis, respectively. Finally, based on the results of the interference occurrence, the proposed PNN-based predictor for the interference arrival prediction can capture correctly the similar distribution function of the coming continuous idle status. en-copyright= kn-copyright= en-aut-name=HouYafei en-aut-sei=Hou en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoKazuto en-aut-sei=Yano en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugaNorisato en-aut-sei=Suga en-aut-mei=Norisato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WebberJulian en-aut-sei=Webber en-aut-mei=Julian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DennoSatoshi en-aut-sei=Denno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakanoToshikazu en-aut-sei=Sakano en-aut-mei=Toshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Wave Engineering Laboratories, Advanced Telecommunications Research Institute International kn-affil= affil-num=3 en-affil=Wave Engineering Laboratories, Advanced Telecommunications Research Institute International kn-affil= affil-num=4 en-affil=Wave Engineering Laboratories, Advanced Telecommunications Research Institute International kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Wave Engineering Laboratories, Advanced Telecommunications Research Institute International kn-affil= en-keyword=Interference detection kn-keyword=Interference detection en-keyword=MUSIC spectrum kn-keyword=MUSIC spectrum en-keyword=interference localization kn-keyword=interference localization en-keyword=prediction of interference arrival kn-keyword=prediction of interference arrival en-keyword=probabilistic neural network kn-keyword=probabilistic neural network END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=413 end-page=421 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Focal Cerebral Hypoperfusion Detected by Arterial Spin-Labeled Magnetic Resonance Imaging in Patients with Migraine Presenting with Neurological Symptoms Concomitant with or without Headache en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated patients with migraine or migraine variants who exhibited focal cerebral hypoperfusion on arterial spin-labeled (ASL) magnetic resonance (MR) imaging along with neurological symptoms. Fourteen patients with migraine demonstrated focal cerebral hypoperfusion. Three other patients did not have a history of recurrent headaches but exhibited comparable cerebral hypoperfusion to migraine patients on ASL-MRI in addition to neurological symptoms. Patients with migraine may present with neurological symptoms associated with cortical spreading depression during, after, or even without a headache phase. Additionally, the isolated neurological symptoms may be caused by a pathophysiology identical to that of migraine but without presenting with recurrent headaches. en-copyright= kn-copyright= en-aut-name=KashiharaKenichi en-aut-sei=Kashihara en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IrisawaMinoru en-aut-sei=Irisawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaoWataru en-aut-sei=Takao en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama Neurology Clinic kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama Kyokuto Hospital kn-affil= affil-num=3 en-affil=Division of Radiology, Okayama Kyokuto Hospital kn-affil= en-keyword=arterial spin-labeled magnetic resonance imaging kn-keyword=arterial spin-labeled magnetic resonance imaging en-keyword=cortical spreading depression kn-keyword=cortical spreading depression en-keyword=migraine complex kn-keyword=migraine complex en-keyword=migraine without headache kn-keyword=migraine without headache en-keyword=vertigo kn-keyword=vertigo END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=363 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Small-for-Gestational-Age Status and the Risk of Kawasaki Disease: A Nationwide Birth Cohort in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kawasaki disease (KD) is a pediatric disease of unknown etiology that commonly affects infants in East Asia. Infants born small for gestational age (SGA) have weaker immune systems and are more susceptible to infection. Using data from a nationwide Japanese birth cohort study conducted in 2010 (n=34,579), we investigated whether SGA increases the risk of KD. SGA was defined as birth weight below the 10th percentile for gestational age. The outcome was hospitalization for KD between 6 and 30 months of age. The association between SGA and hospitalization for KD, adjusted for child and maternal factors, was examined using logistic regression. Of the 231 children hospitalized for KD, 9.5% were SGA. Further statistical analysis showed that SGA did not increase the odds ratio (OR) of hospitalization for KD (adjusted OR 1.12, 95% confidence interval 0.71-1.75). This result was not changed with stratification by early daycare attendance and preterm status. Reasons for the lack of association may include the multifactorial pathogenesis of KD; in addition, the types of infections to which SGA infants are predisposed may differ from those triggering KD. Overall, our large nationwide study found no association between SGA and KD. en-copyright= kn-copyright= en-aut-name=TakanagaSatoe en-aut-sei=Takanaga en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Kawasaki disease (KD) kn-keyword=Kawasaki disease (KD) en-keyword=small for gestational age (SGA) kn-keyword=small for gestational age (SGA) en-keyword=cohort kn-keyword=cohort en-keyword=epidemiology kn-keyword=epidemiology END start-ver=1.4 cd-journal=joma no-vol=416 cd-vols= no-issue=28 article-no= start-page=6679 end-page=6686 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of protein immobilization methods with covalent bonding on paper for paper-based enzyme-linked immunosorbent assay en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, two methods were examined to optimize the immobilization of antibodies on paper when conducting a paper-based enzyme-linked immunosorbent assay (P-ELISA). Human IgG, as a test-capture protein, was immobilized on paper via the formation of Schiff bases. Aldehyde groups were introduced onto the surface of the paper via two methods: NaIO4 and 3-aminopropyltriethoxysilane (APTS) with glutaraldehyde (APTS-glutaraldehyde). In the assay, horseradish peroxidase-conjugated anti-human IgG (HRP-anti-IgG) binds to the immobilized human IgG, and the colorimetric reaction of 3,3′,5,5′-tetramethylbenzyzine (TMB) produces a blue color in the presence of H2O2 and HRP-anti-IgG as a model analyte. The immobilization of human IgG, the enzymatic reaction conditions, and the reduction of the chemical bond between the paper surface and immobilized human IgG all were optimized in order to improve both the analytical performance and the stability. In addition, the thickness of the paper was examined to stabilize the analytical signal. Consequently, the APTS-glutaraldehyde method was superior to the NaIO4 method in terms of sensitivity and reproducibility. Conversely, the reduction of imine to amine with NaBH4 proved to exert only minimal influence on sensitivity and stability, although it tended to degrade reproducibility. We also found that thick paper was preferential when using P-ELISA because a rigid paper substrate prevents distortion of the paper surface that is often caused by repeated washing processes. en-copyright= kn-copyright= en-aut-name=ChenYang en-aut-sei=Chen en-aut-mei=Yang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Paper-based enzyme-linked immunosorbent assay kn-keyword=Paper-based enzyme-linked immunosorbent assay en-keyword=ELISA kn-keyword=ELISA en-keyword=Immobilization kn-keyword=Immobilization en-keyword=Covalent bonding kn-keyword=Covalent bonding en-keyword=Protein kn-keyword=Protein END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=11 article-no= start-page=359 end-page=366 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intravitreal Fluconazole Injection for Fungal Endophthalmitis as Treatment Option in a Patient With End-Stage Liver and Kidney Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endogenous endophthalmitis is an infectious disease of the intraocular tissue that is a consequence of bloodstream infection. The efficacy of intravitreal fluconazole injection to assist low-dose oral fluconazole in fungal endophthalmitis remains unknown in older adults with advanced liver and renal disease. In this case report, a 78-year-old man with hepatitis C virus-related liver cirrhosis and hepatocellular carcinoma who also had end-stage renal disease with temporary nephrostomy noticed blurred vision and showed a large retinal infiltrate with vitreous opacity in the right eye. In the clinical diagnosis of endogenous fungal endophthalmitis, he had an intravitreal injection of 0.1% fluconazole in 0.2 - 0.3 mL every 2 weeks four times in total, in addition to a minimum dose of oral fluconazole. One month before the ophthalmic presentation, he developed a fever and computed tomography scan showed ureterolithiasis with hydronephrosis on the right side, indicating that the renal pelvic stone fell into the ureter. He underwent nephrostomy tube insertion on the right side in the diagnosis of obstructive urinary tract infection. In the course, a potassium hydroxide (KOH) preparation of the urine sediments which were obtained from the nephrostomy tube showed yeast-like fungi, suggestive of Candida, 1 week before the development of eye symptoms. One week after the ophthalmic presentation, the nephrostomy tube at 14 Fr (French gauge) which had been inserted 1 month previously was replaced with a new tube with a larger size at 16 Fr because urine excretion from the tube was reduced. Immediately after the exchange of the nephrostomy tube, a large volume of urine was excreted from the tube. In a week, he had no systemic symptoms and serum C-reactive protein became low. In the meantime, the retinal infiltrate became inactive and vitreous opacity resolved. Intravitreal fluconazole injection is a treatment option for fungal endophthalmitis in the case that a patient cannot undergo vitrectomy and cannot take a maximum dose of fluconazole because of poor renal function. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiokaNaoko en-aut-sei=Yoshioka en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYasushi en-aut-sei=Takahashi en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IguchiYasutaka en-aut-sei=Iguchi en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Ochiai Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Ochiai Hospital kn-affil= en-keyword=Fungal endophthalmitis kn-keyword=Fungal endophthalmitis en-keyword=Intravitreal injection kn-keyword=Intravitreal injection en-keyword=Fluconazole kn-keyword=Fluconazole en-keyword=Nephrostomy kn-keyword=Nephrostomy en-keyword=Urinary tract infection kn-keyword=Urinary tract infection en-keyword=Ureterolithiasis kn-keyword=Ureterolithiasis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=9 article-no= start-page=215 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Study of a Drawing Exactness Assessment Method Using Localized Normalized Cross-Correlations in a Portrait Drawing Learning Assistant System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, portrait drawing has gained significance in cultivating painting skills and human sentiments. In practice, novices often struggle with this art form without proper guidance from professionals, since they lack understanding of the proportions and structures of facial features. To solve this limitation, we have developed a Portrait Drawing Learning Assistant System (PDLAS) to assist novices in learning portrait drawing. The PDLAS provides auxiliary lines as references for facial features that are extracted by applying OpenPose and OpenCV libraries to a face photo image of the target. A learner can draw a portrait on an iPad using drawing software where the auxiliary lines appear on a different layer to the portrait. However, in the current implementation, the PDLAS does not offer a function to assess the exactness of the drawing result for feedback to the learner. In this paper, we present a drawing exactness assessment method using a Localized Normalized Cross-Correlation (NCC) algorithm in the PDLAS. NCC gives a similarity score between the original face photo and drawing result images by calculating the correlation of the brightness distributions. For precise feedback, the method calculates the NCC for each face component by extracting the bounding box. In addition, in this paper, we improve the auxiliary lines for the nose. For evaluations, we asked students at Okayama University, Japan, to draw portraits using the PDLAS, and applied the proposed method to their drawing results, where the application results validated the effectiveness by suggesting improvements in drawing components. The system usability was also confirmed through a questionnaire with a SUS score. The main finding of this research is that the implementation of the NCC algorithm within the PDLAS significantly enhances the accuracy of novice portrait drawings by providing detailed feedback on specific facial features, proving the system's efficacy in art education and training. en-copyright= kn-copyright= en-aut-name=ZhangYue en-aut-sei=Zhang en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KongZitong en-aut-sei=Kong en-aut-mei=Zitong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HsuChen-Chien en-aut-sei=Hsu en-aut-mei=Chen-Chien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Sciences and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Sciences and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Sciences and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=portrait drawing kn-keyword=portrait drawing en-keyword=auxiliary lines kn-keyword=auxiliary lines en-keyword=OpenPose kn-keyword=OpenPose en-keyword=OpenCV kn-keyword=OpenCV en-keyword=normalized cross-correlation (NCC) kn-keyword=normalized cross-correlation (NCC) en-keyword=exactness assessment kn-keyword=exactness assessment END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=10 article-no= start-page=239 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reverse Shape Memory Effect and Toughness Recovery of Ti-10V-2Fe-3Al Alloy kn-title=Ti-10V-2Fe-3Al合金の逆形状記憶効果と靭性回復 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ti-10V-2Fe-3Al alloys exhibit shape memory (SM) and reverse shape memory (RSM) effects. When an alloy sample that has been strained by external force at room temperature is heated, the strain recovers and SM effect develops at around 300℃, but as the temperature increases further, the shape changes in the opposite direction due to RSM effect at around 450℃. This RSM effect has potential applications in forming processes such as thin-walled pipes, but has the disadvantage that the RSM treatment makes the material very brittle. Therefore, in this study, a heat treatment to restore toughness while maintaining the shape after forming was investigated. The alloy quenched from 1050℃ had a microstructure consisting of a β matrix phase and α′′-martensite (α′′Mq). Differential scanning calorimetry (DSC) results showed that the continuous heating process occurred in the following order: α′′Mq → β reverse transformation, ω formation, ω disappearance, thermally induced α′′iso phase formation, α precipitation and α → β transformation. Ageing at 300℃, where the SM effect appears, caused significant embrittlement due to the formation of the ageing ω phase. Ageing treatment at 450℃, where the RSM effect is obtained, resulted in the formation of a fine α phase, which also caused significant embrittlement. On the other hand, additional aging at 600℃ for 1.8 ks after RSM treatment significantly improved the toughness and produced material properties comparable to aerospace material specifications. It was found that the embrittlement in the RSM treatment was due to the precipitation of fine α phase, and that the growth of α phase with a width of about 0.2 ?m or more was required for toughness recovery. It was also found that the specimen shape formed by the RSM treatment hardly changed after the additional heat treatment of 1.8 ks at 600℃. en-copyright= kn-copyright= en-aut-name=TakemotoYoshito en-aut-sei=Takemoto en-aut-mei=Yoshito kn-aut-name=竹元嘉利 kn-aut-sei=竹元 kn-aut-mei=嘉利 aut-affil-num=1 ORCID= en-aut-name=ShinomiyaDaiki en-aut-sei=Shinomiya en-aut-mei=Daiki kn-aut-name=四宮大輝 kn-aut-sei=四宮 kn-aut-mei=大輝 aut-affil-num=2 ORCID= en-aut-name=IshiharaTaiki en-aut-sei=Ishihara en-aut-mei=Taiki kn-aut-name=石原大暉 kn-aut-sei=石原 kn-aut-mei=大暉 aut-affil-num=3 ORCID= en-aut-name=YokotaHiroto en-aut-sei=Yokota en-aut-mei=Hiroto kn-aut-name=横田啓人 kn-aut-sei=横田 kn-aut-mei=啓人 aut-affil-num=4 ORCID= en-aut-name=ArakawaJinta en-aut-sei=Arakawa en-aut-mei=Jinta kn-aut-name=荒川仁太 kn-aut-sei=荒川 kn-aut-mei=仁太 aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学環境生命自然科学学域 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学環境生命自然科学学域 en-keyword=reverse shape memory kn-keyword=reverse shape memory en-keyword=α′′-phase kn-keyword=α′′-phase en-keyword=deformation induced martensite kn-keyword=deformation induced martensite en-keyword=β-type titanium alloy kn-keyword=β-type titanium alloy en-keyword=brittle fracture kn-keyword=brittle fracture en-keyword=toughness kn-keyword=toughness en-keyword=shape recovery kn-keyword=shape recovery en-keyword=ω-phase kn-keyword=ω-phase en-keyword=variant kn-keyword=variant END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=e107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of psychological first aid in infectious disease pandemics: An overview of systematic reviews en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is insufficient research on the usefulness of psychological interventions, such as psychological first aid (PFA), during outbreaks. We searched for and critically appraised systematic reviews that examined the effectiveness of PFA during infectious disease outbreaks, such as the novel coronavirus disease (COVID-19). Systematic reviews that examined the efficacy of PFA in the severe acute respiratory syndrome, Middle East respiratory syndrome coronavirus, Ebola virus disease, and COVID-19 outbreaks were searched through PubMed on February 19, 2021. The three included systematic reviews were critically appraised and assessed using AMSTAR-2. One review's overall confidence in its findings was evaluated as “high,” which suggested that PFA training had a favorable effect on healthcare personnel. Furthermore, the review also demonstrated that PFA was commonly used during outbreaks and could be delivered through multiple methods, such as a phone or video call. Although it was anticipated that PFA would improve subjective well-being, reports showed no evidence of reduced depression or insomnia. Future studies should examine additional numbers of PFA recipients and conduct quasi-experimental studies to better understand the effectiveness of PFA. Evidence on its effectiveness in infectious disease outbreaks is still lacking, along with research and evaluation methods. Quasi-experimental studies, such as comparisons with other psychological interventions, are required to better understand the effectiveness of PFA. en-copyright= kn-copyright= en-aut-name=KodaMasahide en-aut-sei=Koda en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HorinouchiToru en-aut-sei=Horinouchi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OyaNozomu en-aut-sei=Oya en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiMorio en-aut-sei=Aki en-aut-mei=Morio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IrikiAkihisa en-aut-sei=Iriki en-aut-mei=Akihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaKazufumi en-aut-sei=Yoshida en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaYusuke en-aut-sei=Ogawa en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KugaHironori en-aut-sei=Kuga en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoTomohiro en-aut-sei=Nakao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Co‐Learning Community Healthcare Re‐Innovation Office, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Psychiatry, Hokkaido University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Psychiatry, Graduate School of Medical Science, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Psychiatry, Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Osaka Psychiatric Medical Center kn-affil= affil-num=6 en-affil=Department of Health Promotion and Human Behavior, Graduate School of Medicine/School of Public Health, Kyoto University kn-affil= affil-num=7 en-affil=Department of Healthcare Epidemiology, School of Public Health in the Graduate School of Medicine, Kyoto University kn-affil= affil-num=8 en-affil=National Center for Cognitive Behavior Therapy and Research, National Center of Neurology and Psychiatry kn-affil= affil-num=9 en-affil=Department of Neuropsychiatry, Graduate School of Medical Sciences, Kyushu University kn-affil= en-keyword=mental health kn-keyword=mental health en-keyword=pandemic kn-keyword=pandemic en-keyword=psychological first aid kn-keyword=psychological first aid en-keyword=psychosocial support kn-keyword=psychosocial support END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=11 article-no= start-page=1769 end-page=1786 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240824 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nutrient Requirements Shape the Preferential Habitat of Allorhizobium vitis VAR03-1, a Commensal Bacterium, in the Rhizosphere of Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=A diverse range of commensal bacteria inhabit the rhizosphere, influencing host plant growth and responses to biotic and abiotic stresses. While root-released nutrients can define soil microbial habitats, the bacterial factors involved in plant?microbe interactions are not well characterized. In this study, we investigated the colonization patterns of two plant disease biocontrol agents, Allorhizobium vitis VAR03-1 and Pseudomonas protegens Cab57, in the rhizosphere of Arabidopsis thaliana using Murashige and Skoog (MS) agar medium. VAR03-1 formed colonies even at a distance from the roots, preferentially in the upper part, while Cab57 colonized only the root surface. The addition of sucrose to the agar medium resulted in excessive proliferation of VAR03-1, similar to its pattern without sucrose, whereas Cab57 formed colonies only near the root surface. Overgrowth of both bacterial strains upon nutrient supplementation inhibited host growth, independent of plant immune responses. This inhibition was reduced in the VAR03-1 ΔrecA mutant, which exhibited increased biofilm formation, suggesting that some activities associated with the free-living lifestyle rather than the sessile lifestyle may be detrimental to host growth. VAR03-1 grew in liquid MS medium with sucrose alone, while Cab57 required both sucrose and organic acids. Supplementation of sugars and organic acids allowed both bacterial strains to grow near and away from Arabidopsis roots in MS agar. These results suggest that nutrient requirements for bacterial growth may determine their growth habitats in the rhizosphere, with nutrients released in root exudates potentially acting as a limiting factor in harnessing microbiota. en-copyright= kn-copyright= en-aut-name=HemeldaNiarsi Merry en-aut-sei=Hemelda en-aut-mei=Niarsi Merry kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BaoJiyuan en-aut-sei=Bao en-aut-mei=Jiyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Commensal bacteria kn-keyword=Commensal bacteria en-keyword=Nutrient requirements kn-keyword=Nutrient requirements en-keyword=Organic acids kn-keyword=Organic acids en-keyword=Plant-microbe interactions kn-keyword=Plant-microbe interactions en-keyword=Rhizosphere kn-keyword=Rhizosphere en-keyword=Sugars kn-keyword=Sugars END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=17 article-no= start-page=4368 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antibacterial Dental Adhesive Containing Cetylpyridinium Chloride Montmorillonite en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral bacteria cause tooth caries and periodontal disease. Much research is being conducted to prevent both major oral diseases by rendering dental materials' antimicrobial potential. However, such antimicrobial materials are regarded as 'combination' products and face high hurdles for regulatory approval. We loaded inorganic montmorillonite with the antimicrobial agent cetylpyridinium chloride, referred to below as 'CPC-Mont'. CPC-Mont particles in a 1, 3 and 5 wt% concentration were added to the considered gold-standard self-etch adhesive Clearfil SE Bond 2 ('CSE2'; Kuraray Noritake) to render its antibacterial potential (CSE2 without CPC-Mont served as control). Besides measuring (immediate) bonding effectiveness and (aged) bond durability to dentin, the antibacterial activity against S. mutans and the polymerization-conversion rate was assessed. Immediate and aged bond strength was not affected by 1 and 3 wt% CPC-Mont addition, while 5 wt% CPC-Mont significantly lowered bond strength and bond durability. The higher the concentration of the antimicrobial material added, the stronger the antimicrobial activity. Polymerization conversion was not affected by the CPC-Mont addition in any of the three concentrations. Hence, adding 3 wt% CPC-Mont to the two-step self-etch adhesive rendered additional antimicrobial potential on top of its primary bonding function. en-copyright= kn-copyright= en-aut-name=OkazakiYohei en-aut-sei=Okazaki en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamoriKiichi en-aut-sei=Nakamori en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaoChenmin en-aut-sei=Yao en-aut-mei=Chenmin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AhmedMohammed H. en-aut-sei=Ahmed en-aut-mei=Mohammed H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MercelisBenjamin en-aut-sei=Mercelis en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaYasuhiro en-aut-sei=Yoshida en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeYasuhiko en-aut-sei=Abe en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Van MeerbeekMeerbeek, Bart en-aut-sei=Van Meerbeek en-aut-mei=Meerbeek, Bart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=2 en-affil=Department of Advanced Prosthodontics, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=3 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=5 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=6 en-affil=Advanced Research Center for Oral and Craniofacial Science, Okayama University Dental School kn-affil= affil-num=7 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=8 en-affil=Department of Biomaterials and Bioengineering, Faculty of Dental Medicine, Hokkaido University kn-affil= affil-num=9 en-affil=Department of Advanced Prosthodontics, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=10 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=11 en-affil=Department of Pathology & Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=dental adhesive kn-keyword=dental adhesive en-keyword=antibacterial agent kn-keyword=antibacterial agent en-keyword=dentin kn-keyword=dentin en-keyword=degree of conversion kn-keyword=degree of conversion en-keyword=micro tensile bond strength kn-keyword=micro tensile bond strength en-keyword=scanning microscopy kn-keyword=scanning microscopy END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=16 article-no= start-page=1373 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240817 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Direct Binding of Synaptopodin 2-Like Protein to Alpha-Actinin Contributes to Actin Bundle Formation in Cardiomyocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synaptopodin 2-like protein (SYNPO2L) is localized in the sarcomere of cardiomyocytes and is involved in heart morphogenesis. However, the molecular function of SYNPO2L in the heart is not fully understood. We investigated the interaction of SYNPO2L with sarcomeric alpha-actinin and actin filaments in cultured mouse cardiomyocytes. Immunofluorescence studies showed that SYNPO2L colocalized with alpha-actinin and actin filaments at the Z-discs of the sarcomere. Recombinant SYNPO2La or SYNPO2Lb caused a bundling of the actin filaments in the absence of alpha-actinin and enhanced the alpha-actinin-dependent formation of actin bundles. In addition, high-speed atomic force microscopy revealed that SYNPO2La directly bound to alpha-actinin via its globular ends. The interaction between alpha-actinin and SYNPO2La fixed the movements of the two proteins on the actin filaments. These results strongly suggest that SYNPO2L cooperates with alpha-actinin during actin bundle formation to facilitate sarcomere formation and maintenance. en-copyright= kn-copyright= en-aut-name=YamadaHiroshi en-aut-sei=Yamada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsakaHirona en-aut-sei=Osaka en-aut-mei=Hirona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TatsumiNanami en-aut-sei=Tatsumi en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArakiMiu en-aut-sei=Araki en-aut-mei=Miu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbeTadashi en-aut-sei=Abe en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaiharaKeiko en-aut-sei=Kaihara en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiKen en-aut-sei=Takahashi en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakashimaEizo en-aut-sei=Takashima en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchihashiTakayuki en-aut-sei=Uchihashi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakeiKohji en-aut-sei=Takei en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Science, Nagoya University kn-affil= affil-num=3 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Division of Malaria Research, Proteo-Science Center, Ehime University kn-affil= affil-num=9 en-affil=Graduate School of Science, Nagoya University kn-affil= affil-num=10 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SYNPO2L kn-keyword=SYNPO2L en-keyword=actinin kn-keyword=actinin en-keyword=actin kn-keyword=actin en-keyword=sarcomere kn-keyword=sarcomere en-keyword=cardiomyocyte kn-keyword=cardiomyocyte END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=16 article-no= start-page=4108 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Scaffold Geometrical Structure on Macrophage Polarization during Bone Regeneration Using Honeycomb Tricalcium Phosphate en-subtitle= kn-subtitle= en-abstract= kn-abstract=The polarization balance of M1/M2 macrophages with different functions is important in osteogenesis and bone repair processes. In a previous study, we succeeded in developing honeycomb tricalcium phosphate (TCP), which is a cylindrical scaffold with a honeycomb arrangement of straight pores, and we demonstrated that TCP with 300 and 500 mu m pore diameters (300TCP and 500TCP) induced bone formation within the pores. However, the details of the influence of macrophage polarization on bone formation using engineered biomaterials, especially with respect to the geometric structure of the artificial biomaterials, are unknown. In this study, we examined whether differences in bone tissue formation due to differences in TCP geometry were due to the polarity of the assembling macrophages. Immunohistochemistry for IBA-1, iNOS, and CD163 single staining was performed. The 300TCP showed a marked infiltration of iNOS-positive cells, which are thought to be M1 macrophages, during the osteogenesis process, while no involvement of CD163-positive cells, which are thought to be M2 macrophages, was observed in the TCP pores. In addition, 500TCP showed a clustering of iNOS-positive cells and CD163-positive cells at 2 weeks, suggesting the involvement of M2 macrophages in the formation of bone tissue in the TCP pores. In conclusion, we demonstrated for the first time that the geometrical structure of the artificial biomaterial, i.e., the pore size of honeycomb TCP, affects the polarization of M1/2 macrophages and bone tissue formation in TCP pores. en-copyright= kn-copyright= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujigiwaHidetsugu en-aut-sei=Tsujigiwa en-aut-mei=Hidetsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChangAnqi en-aut-sei=Chang en-aut-mei=Anqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PiaoTianyan en-aut-sei=Piao en-aut-mei=Tianyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InadaYasunori en-aut-sei=Inada en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ArashimaTakuma en-aut-sei=Arashima en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorimatsuAyumi en-aut-sei=Morimatsu en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=honeycomb TCP kn-keyword=honeycomb TCP en-keyword=bone formation kn-keyword=bone formation en-keyword=macrophages kn-keyword=macrophages en-keyword=polarization kn-keyword=polarization END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=2 article-no= start-page=394 end-page=408 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The neurotoxicity of psychoactive phenethylamines “2C series” in cultured monoaminergic neuronal cell lines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The aim of this study was to evaluate the neurotoxicity of psychoactive abused 2,5-dimethoxy-substituted phenethylamines “2C series” in monoaminergic neurons.
Methods After the exposure to “2C series”, 2,5-dimethoxy-4-propylthiophenethylamine (2C-T-7), 2,5-dimethoxy-4-isopropylthiophenethylamine (2C-T-4), 2,5-dimethoxy-4-ethylthiophenthylamine (2C-T-2), 2,5-dimethoxy-4-iodophenethylamine (2C-I) or 2,5-dimethoxy-4-chlorophenethylamine (2C-C), we examined their neurotoxicity, morphological changes, and effects of concomitant exposure to 3,4-methylenedioxymethamphetamine (MDMA) or methamphetamine (METH), using cultured neuronal dopaminergic CATH.a cells and serotonin-containing B65 cells.
Results Single dose exposure to “2C series” for 24 h showed significant cytotoxicity as increase in lactate dehydrogenase (LDH) release from both monoaminergic neurons: 2C-T-7, 2C-C (EC50; 100 ?M)?>?2C-T-2 (150 ?M), 2C-T-4 (200 ?M)?>?2C-I (250 ?M) in CATH.a cells and 2C-T-7, 2C-I (150 ?M)?>?2C-T-2 (250 ?M)?>?2C-C, 2C-T-4 (300 ?M) in B65 cells. The “2C series”-induced neurotoxicity in both cells was higher than that of MDMA or METH (EC50:???1?2 mM). In addition, apoptotic morphological changes were observed at relatively lower concentrations of “2C series”. The concomitant exposure to non-toxic dose of MDMA or METH synergistically enhanced 2C series drugs-induced LDH release and apoptotic changes in B65 cells, but to a lesser extent in CATH.a cells. In addition, the lower dose of 2C-T-7, 2C-T-2 or 2C-I promoted reactive oxygen species production in the mitochondria of B65 cells, even at the early stages (3 h) without apparent morphological changes.
Conclusion The 2,5-dimethoxy-substitution of “2C series” induced severe neurotoxicity in both dopaminergic and serotonin-containing neurons. The non-toxic dose of MDMA or METH synergistically enhanced its neurotoxicity in serotonergic neurons. en-copyright= kn-copyright= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunadaMasahiko en-aut-sei=Funada en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Drug Dependence, National Institute of Mental Health, National Center of Neurology and Psychiatry kn-affil= en-keyword=Psychoactive drugs kn-keyword=Psychoactive drugs en-keyword=2,5-Dimethoxy-substituted phenethylamines kn-keyword=2,5-Dimethoxy-substituted phenethylamines en-keyword=Neurotoxicity kn-keyword=Neurotoxicity en-keyword=Serotonin-containing neurons kn-keyword=Serotonin-containing neurons en-keyword=Dopamine neurons kn-keyword=Dopamine neurons en-keyword=Reactive oxygen species kn-keyword=Reactive oxygen species END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=100347 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduction with zinc - Impact on the determination of nitrite and nitrate ions using microfluidic paper-based analytical devices en-subtitle= kn-subtitle= en-abstract= kn-abstract=We used a microfluidic paper-based analytical device (mu PAD) to investigate the influence that zinc reduction exerts on the determination of nitrite and nitrate ions in natural water samples. The mu PAD consists of layered channels for the reduction of nitrate to nitrite with zinc powder and the subsequent detection of nitrite with Griess reagent. The amount of zinc, number of layers, and reaction time for the reduction were optimized to obtain an intense signal for nitrate. Initially, the sensitivity to nitrate corresponded to 55% that of nitrite, which implied an incomplete reduction. We found, however, that zinc decreased the sensitivity to nitrite in both the mu PAD and spectrophotometry. The sensitivity to nitrite was decreased by 48% in spectrophotometry and 68% in the mu PAD following the reaction with zinc. One of the reasons for the decreased sensitivity is attributed to the production of ammonia, as we elucidated that both nitrite and nitrate produced ammonia via the reaction with zinc. The results suggest that the total concentration of nitrite and nitrate must be corrected by constructing a calibration curve for nitrite with zinc, in addition to developing curves for nitrate with zinc and for nitrite without zinc. Using these calibration curves, the absorbance at different concentration ratios of nitrite and nitrate ions could be reproduced via calculation using the calibration curves with zinc for nitrite and nitrate. Eventually, the developed mu PAD was applied to the determination of nitrite and nitrate ions in natural water samples, and the results were compared with those using a conventional spectrophotometric method. The results of the mu PAD are in good agreement with those of conventional spectrophotometry, which suggests that the mu PAD is reliable for the measurement of nitrite and nitrate ions in natural water samples. en-copyright= kn-copyright= en-aut-name=UmedaMika I. en-aut-sei=Umeda en-aut-mei=Mika I. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiTakatoshi en-aut-sei=Fujii en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HinoEiichi en-aut-sei=Hino en-aut-mei=Eiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DateYusuke en-aut-sei=Date en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AokiKaoru en-aut-sei=Aoki en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=4 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=5 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=6 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=7 en-affil=Okayama University kn-affil= en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Nitrite ion kn-keyword=Nitrite ion en-keyword=Nitrate ion kn-keyword=Nitrate ion en-keyword=On-site analysis kn-keyword=On-site analysis en-keyword=Environmental analysis kn-keyword=Environmental analysis END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=3 article-no= start-page=e70003 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Forgetfulness in adult attention-deficit/hyperactivity disorder masks transient epileptic amnesia: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Inattention due to attention-deficit/hyperactivity disorder (ADHD) can lead to forgetfulness. Transient epileptic amnesia (TEA) can cause forgetfulness, similar to ADHD. We report a patient with ADHD who developed TEA.
Case Presentation: The patient was a 40-year-old woman with ADHD. She has been prone to forgetfulness since childhood. Two years before visiting our outpatient clinic, she had begun to occasionally forget events that had occurred several days earlier. However, she was largely unaware of the emergence of new amnestic symptoms. She had also begun to experience various other amnestic symptoms 2 months before she visited our clinic, which prompted her to visit our outpatient clinic. The combination of a detailed interview, electroencephalography (EEG) examination, and consideration of TEA enabled us to diagnose her with TEA and provide treatment accordingly. In our patient, daily forgetfulness due to ADHD delayed the recognition of new additional forgetfulness attributed to TEA.
Conclusion: Psychiatrists need to consider TEA when patients with ADHD present with changes in or exacerbation of forgetfulness. We report a patient with ADHD who developed TEA. In our patient, daily forgetfulness due to ADHD delayed the recognition of new additional forgetfulness attributed to TEA. Psychiatrists need to consider TEA when patients with ADHD present with changes or exacerbation of forgetfulness. en-copyright= kn-copyright= en-aut-name=FukaoTakashi en-aut-sei=Fukao en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraMasaki en-aut-sei=Fujiwara en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaYuto en-aut-sei=Yamada en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoShinji en-aut-sei=Sakamoto en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, OkayamaUniversity Hospital kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, OkayamaUniversity Hospital kn-affil= affil-num=3 en-affil=Department of Neuropsychiatry, OkayamaUniversity Hospital kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, OkayamaUniversity Hospital kn-affil= affil-num=5 en-affil=Okayama University Hospital Gender Center kn-affil= affil-num=6 en-affil=Department of Neuropsychiatry, OkayamaUniversity Faculty of Medicine, Dentistry andPharmaceutical Sciences kn-affil= en-keyword=anti-seizure medications kn-keyword=anti-seizure medications en-keyword=attention-deficit/hyperactivity disorder kn-keyword=attention-deficit/hyperactivity disorder en-keyword=electroencephalography kn-keyword=electroencephalography en-keyword=transient epileptic amnesia kn-keyword=transient epileptic amnesia END start-ver=1.4 cd-journal=joma no-vol=371 cd-vols= no-issue= article-no= start-page=fnae053 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regulatory role of VvsB protein on serine protease activity of VvsA in Vibrio vulnificus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background:Vibrio vulnificus NCIMB2137, a Gram-negative, metalloprotease negative estuarine strain was isolated from a diseased eel. A 45 kDa chymotrypsin-like alkaline serine protease known as VvsA has been recently reported as one of the major virulence factor responsible for the pathogenesis of this strain. The vvsA gene along with a downstream gene vvsB, whose function is still unknown constitute an operon designated as vvsAB. Objective: This study examines the contribution of VvsB to the functionality of VvsA. Method: In this study, VvsB was individually expressed using Rapid Translation System (RTS system), followed by an analysis of its role in regulating the serine protease activity of VvsA. Result: The proteolytic activity of VvsA increased upon the addition of purified VvsB to the culture supernatant of V. vulnificus. However, the attempts of protein expression using an E. coli system revealed a noteworthy observation that protein expression from the vvsA gene exhibited higher protease activity compared to that from the vvsAB gene within the cytoplasmic fraction. These findings suggest an intricate interplay between VvsB and VvsA, where VvsB potentially interacts with VvsA inside the bacterium and suppress the proteolytic activity. While outside the bacterial milieu, VvsB appears to stimulate the activation of inactive VvsA. Conclusion: The findings suggest that Vibrio vulnificus regulates VvsA activity through the action of VvsB, both intracellularly and extracellularly, to ensure its survival. en-copyright= kn-copyright= en-aut-name=KawaseTomoka en-aut-sei=Kawase en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biotechnology, Brainware University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=RTS system kn-keyword=RTS system en-keyword=in vitro cell-free translation system, PU kn-keyword=in vitro cell-free translation system, PU en-keyword=Proteinase unit, VvsA kn-keyword=Proteinase unit, VvsA en-keyword=Vibrio vulnificus serine protease, SD kn-keyword=Vibrio vulnificus serine protease, SD en-keyword=Shine-Dalgarno sequence kn-keyword=Shine-Dalgarno sequence END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=32 article-no= start-page=23177 end-page=23183 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lead-free iron-doped Cs3Bi2Br9 perovskite with tunable properties en-subtitle= kn-subtitle= en-abstract= kn-abstract=Perovskite based on cesium bismuth bromide offers a compelling, non-toxic alternative to lead-containing counterparts in optoelectronic applications. However, its widespread usage is hindered by its wide bandgap. This study investigates a significant bandgap tunability achieved by introducing Fe doping into the inorganic, lead-free, non-toxic, and stable Cs3Bi2Br9 perovskite at varying concentrations. The materials were synthesized using a facile method, with the aim of tuning the optoelectronic properties of the perovskite materials. Characterization through techniques such as X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, energy dispersive spectroscopy (EDS), and UV-vis spectroscopy was conducted to elucidate the transformation mechanism of the doping materials. The substitution process results in a significant change in the bandgap energy, transforming from the pristine Cs3Bi2Br9 with a bandgap of 2.54 eV to 1.78 eV upon 70% Fe doping. The addition of 50% Fe in Cs3Bi2Br9 leads to the formation of the orthorhombic structure in Cs2(Bi,Fe)Br5 perovskite, while complete Fe alloying at 100% results in the phase formation of CsFeBr4 perovskite. Our findings on regulation of bandgap energy and crystal structure through B site substitution hold significant promise for applications in optoelectronics. en-copyright= kn-copyright= en-aut-name=HtunThiri en-aut-sei=Htun en-aut-mei=Thiri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ElattarAmr en-aut-sei=Elattar en-aut-mei=Amr kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ElbohyHytham en-aut-sei=Elbohy en-aut-mei=Hytham kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsutsumiKosei en-aut-sei=Tsutsumi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoriganeKazumasa en-aut-sei=Horigane en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GuXiaoyu en-aut-sei=Gu en-aut-mei=Xiaoyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiHiroo en-aut-sei=Suzuki en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishikawaTakeshi en-aut-sei=Nishikawa en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KyawAung Ko Ko en-aut-sei=Kyaw en-aut-mei=Aung Ko Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HayashiYasuhiko en-aut-sei=Hayashi en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Ain Shams University kn-affil= affil-num=3 en-affil=Physics Department, Faculty of Science, Damietta University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Guangdong University Key Laboratory for Advanced Quantum Dot Displays and Lighting and Department of Electronic & Electrical Engineering, Southern University of Science and Technology kn-affil= affil-num=8 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Guangdong University Key Laboratory for Advanced Quantum Dot Displays and Lighting and Department of Electronic & Electrical Engineering, Southern University of Science and Technology kn-affil= affil-num=11 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=5 article-no= start-page=463 end-page=483 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Detailed Re-Examination of the Period Gene Rescue Experiments Shows That Four to Six Cryptochrome-Positive Posterior Dorsal Clock Neurons (DN1p) of Drosophila melanogaster Can Control Morning and Evening Activity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Animal circadian clocks play a crucial role in regulating behavioral adaptations to daily environmental changes. The fruit fly Drosophila melanogaster exhibits 2 prominent peaks of activity in the morning and evening, known as morning (M) and evening (E) peaks. These peaks are controlled by 2 distinct circadian oscillators located in separate groups of clock neurons in the brain. To investigate the clock neurons responsible for the M and E peaks, a cell-specific gene expression system, the GAL4-UAS system, has been commonly employed. In this study, we re-examined the two-oscillator model for the M and E peaks of Drosophila by utilizing more than 50 Gal4 lines in conjunction with the UAS-period16 line, which enables the restoration of the clock function in specific cells in the period (per) null mutant background. Previous studies have indicated that the group of small ventrolateral neurons (s-LNv) is responsible for controlling the M peak, while the other group, consisting of the 5th ventrolateral neuron (5th LNv) and the three cryptochrome (CRY)-positive dorsolateral neurons (LNd), is responsible for the E peak. Furthermore, the group of posterior dorsal neurons 1 (DN1p) is thought to also contain M and E oscillators. In this study, we found that Gal4 lines directed at the same clock neuron groups can lead to different results, underscoring the fact that activity patterns are influenced by many factors. Nevertheless, we were able to confirm previous findings that the entire network of circadian clock neurons controls M and E peaks, with the lateral neurons playing a dominant role. In addition, we demonstrate that 4 to 6 CRY-positive DN1p cells are sufficient to generate M and E peaks in light-dark cycles and complex free-running rhythms in constant darkness. Ultimately, our detailed screening could serve as a catalog to choose the best Gal4 lines that can be used to rescue per in specific clock neurons. en-copyright= kn-copyright= en-aut-name=SekiguchiManabu en-aut-sei=Sekiguchi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ReinhardNils en-aut-sei=Reinhard en-aut-mei=Nils kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukudaAyumi en-aut-sei=Fukuda en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatohShun en-aut-sei=Katoh en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RiegerDirk en-aut-sei=Rieger en-aut-mei=Dirk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Helfrich-F?rsterCharlotte en-aut-sei=Helfrich-F?rster en-aut-mei=Charlotte kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Neurobiology and Genetics, Theodor-Boveri Institute, Biocenter, University of W?rzburg kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Neurobiology and Genetics, Theodor-Boveri Institute, Biocenter, University of W?rzburg kn-affil= affil-num=6 en-affil=Neurobiology and Genetics, Theodor-Boveri Institute, Biocenter, University of W?rzburg kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=period kn-keyword=period en-keyword=GAL4-UAS kn-keyword=GAL4-UAS en-keyword=clock neuron kn-keyword=clock neuron en-keyword=activity rhythm kn-keyword=activity rhythm en-keyword=two-oscillator model kn-keyword=two-oscillator model END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=29 article-no= start-page=5836 end-page=5847 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between π?A isotherms and single microgel/microgel array structures revealed via the direct visualization of microgels at the air/water interface en-subtitle= kn-subtitle= en-abstract= kn-abstract=The structures of single microgels and microgel arrays formed at the air/water interface were visualized directly, and their structures correlated with π?A isotherms in order to understand the compression behavior of soft and deformable microgels at this interface. Large microgels (ca. 4 μm) were synthesized so that these can be clearly visualized at the air/water interface, even under high compression, and a series of microgel compression experiments were directly evaluated using a Langmuir trough equipped with a fluorescence microscope. The experiments revealed that upon compressing the microgel arrays at the interface voids disappeared and colloidal crystallinity increased. However, the colloidal crystallinity decreased when the microgel arrays were strongly compressed. In addition, when the structures were observed at higher magnification, it became clear that the single microgel structures, when visualized from above, changed from circular to polygonal upon compressing the microgel array. The results of this study can be expected to improve the understanding of the compression behavior of microgel arrays adsorbed at the air/water interface and will thus be useful for the creation of new functional microgel stabilizers with potential applications in e.g., bubbles and emulsions. en-copyright= kn-copyright= en-aut-name=KawamotoTakahisa en-aut-sei=Kawamoto en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MinatoHaruka en-aut-sei=Minato en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiDaisuke en-aut-sei=Suzuki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=13 article-no= start-page=3809 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240628 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes in Working Situations of Employed Long COVID Patients: Retrospective Study in Japanese Outpatient Clinic en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: The present study aimed to uncover the impact of long COVID on the working situations of Japanese patients. Methods: Changes in the working situations of the patients who visited our long COVID clinic were evaluated from medical records for the aspects of physical status, quality of life (QOL), and mental conditions.
Results: Of 846 long COVID patients who visited our clinic from February 2021 to December 2023, 545 employed patients aged between 18 and 65 years were included in this study. A total of 295 patients (54.1%) with long COVID (median age: 43 years, female: 55.6%) experienced changes in their working status. Those patients included 220 patients (40.4%) who took a leave of absence, 53 patients (9.7%) who retired, and 22 patients (4%) with reduced working hours. Most of the patients (93.2%) with changes in working conditions had mild disease severity in the acute phase of COVID-19. The majority of those patients with mild disease severity (58.8%) were infected in the Omicron-variant phase and included 65.3% of the female patients. The major symptoms in long COVID patients who had changes in their working situations were fatigue, insomnia, headache, and dyspnea. Scores indicating fatigue and QOL were worsened in long COVID patients who had changes in their working situations. In addition, 63.7% of the long COVID patients with changes in their working situations had decreases in their incomes.
Conclusions: Changes in the working situation of long COVID patients who were employed had a negative impact on the maintenance of their QOL. en-copyright= kn-copyright= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SunadaNaruhiko en-aut-sei=Sunada en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=employment kn-keyword=employment en-keyword=job retirement kn-keyword=job retirement en-keyword=leave of absence kn-keyword=leave of absence en-keyword=long COVID kn-keyword=long COVID en-keyword=omicron variant kn-keyword=omicron variant en-keyword=post-COVID-19 condition kn-keyword=post-COVID-19 condition END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=14 article-no= start-page=10349 end-page=10354 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formal One Carbon Deletion of Indoline Hemiaminals under Tautomeric Control to Access 2-Aminobenzyl Compounds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unprecedented tert-BuOK-mediated one carbon deletion of indoline hemiaminals has been achieved.

Graphene nanosheet suspension has attracted attention as a next-generation nanofluid because of its high thermal conductivity and low pressure drop, while being dispersed stably without any additives. Graphene-based nanofluids have been mostly investigated using graphene oxide, and there are a few studies on pure graphene because of the limitation in mass production and stabilization at high concentrations of graphene. In this study, we prepared a 10?wt. % high-concentration few-layer graphene suspension by pulverizing graphite particles. Scanning electron microscopy, atomic force microscopy, and Raman spectra confirmed the few-layer graphene is formed in the suspension. The thermal conductivity of the suspension increased with concentration and suddenly jumped at a specific concentration. Furthermore, a significant improvement in thermal conductivity of >40% compared to base liquid was confirmed at 10?wt. % graphene content. A similar trend was observed for electrical resistance; 10?wt. % graphene suspension showed 62% lower resistance than that of 1?wt. %. These results suggest the percolation of graphene in a liquid, which has not been observed for graphene-based materials in previous research. en-copyright= kn-copyright= en-aut-name=IshiiKeiko en-aut-sei=Ishii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgiyamaTakahiro en-aut-sei=Ogiyama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FumotoKoji en-aut-sei=Fumoto en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=College of Science and Engineering, Chuo University kn-affil= affil-num=2 en-affil=College of Science and Engineering, Aoyama Gakuin University kn-affil= affil-num=3 en-affil=College of Science and Engineering, Aoyama Gakuin University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=13 article-no= start-page=e34206 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resolvin D2-induced reparative dentin and pulp stem cells after pulpotomy in a rat model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Vital pulp therapy (VPT) is performed to preserve dental pulp. However, the biocompatibility of the existing materials is of concern. Therefore, novel materials that can induce pulp healing without adverse effects need to be developed. Resolvin D2 (RvD2), one of specialized pro-resolving mediators, can resolve inflammation and promote the healing of periapical lesions. Therefore, RvD2 may be suitable for use in VPT. In the present study, we evaluated the efficacy of RvD2 against VPT using in vivo and in vitro models.
Methods: First molars of eight-week-old male Sprague?Dawley rats were used for pulpotomy. They were then divided into three treatment groups: RvD2, phosphate-buffered saline, and calcium hydroxide groups. Treatment results were assessed using radiological, histological, and immunohistochemical (GPR18, TNF-α, Ki67, VEGF, TGF-β, CD44, CD90, and TRPA1) analyses. Dental pulp-derived cells were treated with RvD2 in vitro and analyzed using cell-proliferation and cell-migration assays, real-time PCR (Gpr18, Tnf-α, Il-1β, Tgf-β, Vegf, Nanog, and Trpa1), ELISA (VEGF and TGF-β), immunocytochemistry (TRPA1), and flow cytometry (dental pulp stem cells: DPSCs).
Results: The formation of calcified tissue in the pulp was observed in the RvD2 and calcium hydroxide groups. RvD2 inhibited inflammation in dental pulp cells. RvD2 promoted cell proliferation and migration and the expression of TGF-β and VEGF in vitro and in vivo. RvD2 increased the number of DPSCs. In addition, RvD2 suppressed TRPA1 expression as a pain receptor.
Conclusion: RvD2 induced the formation of reparative dentin, anti-inflammatory effects, and decreased pain, along with the proliferation of DPSCs via the expression of VEGF and TGF-β, on the pulp surface in pulpotomy models. en-copyright= kn-copyright= en-aut-name=YonedaMitsuhiro en-aut-sei=Yoneda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IdeguchiHidetaka en-aut-sei=Ideguchi en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AriasZulema en-aut-sei=Arias en-aut-mei=Zulema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=4 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Molecular Biology and Biochemistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Dental pulp kn-keyword=Dental pulp en-keyword=Regeneration kn-keyword=Regeneration en-keyword=Pulp-capping agents kn-keyword=Pulp-capping agents en-keyword=Specialized pro-resolving mediators kn-keyword=Specialized pro-resolving mediators en-keyword=Resolvin D2 kn-keyword=Resolvin D2 en-keyword=Calcification kn-keyword=Calcification en-keyword=Cytokine kn-keyword=Cytokine en-keyword=TRPA1 kn-keyword=TRPA1 en-keyword=Animal model kn-keyword=Animal model END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of membranous nephropathy complicated by Cronkhite?Canada syndrome successfully treated with mizoribine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cronkhite?Canada syndrome (CCS) is a non-hereditary disorder characterized by non-neoplastic hamartomatous gastrointestinal polyposis, hair loss, nail atrophy, hyperpigmentation, and diarrhea. While the relationship between CCS and nephritis remains unclear, seven cases of nephritis complicated by CCS have been reported to date, all of which were membranous nephropathy (MN). A 57-year-old man presented with taste disturbance, hair loss, nail plate atrophy, skin pigmentation, and frequent diarrhea. Endoscopic findings showed multiple polyposis of the stomach and large intestine. Given the above, he was diagnosed with CCS. The symptoms gradually improved with prednisolone treatment, although urinary protein and hypoproteinemia appeared during the tapering of prednisolone. He was diagnosed with MN using a renal biopsy, and immunofluorescence microscopy with IgG subclass staining showed predominantly diffuse granular capillary wall staining of IgG4. The cause of secondary MN was not found, including malignant tumors. Nephrotic-range proteinuria persisted despite treatment with prednisolone and cyclosporine. Additional treatment with mizoribine resulted in incomplete remission type 1 of nephrotic syndrome, suggesting that mizoribine may be a treatment option for patients with CCS with steroid-resistant MN. Considering a high prevalence of hypoproteinemia due to chronic diarrhea and protein-losing enteropathy in patients with CCS, proteinuria might be overlooked; thus, follow-up urinalysis would be recommended in patients with CCS. en-copyright= kn-copyright= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoShiho en-aut-sei=Morimoto en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cronkhite?Canada syndrome kn-keyword=Cronkhite?Canada syndrome en-keyword=Membranous nephropathy kn-keyword=Membranous nephropathy en-keyword=Nephrotic syndrome kn-keyword=Nephrotic syndrome en-keyword=Mizoribine kn-keyword=Mizoribine END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue= article-no= start-page=102405 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crystal plasticity analysis of fatigue crack initiation site considering crystallographic orientation in Ti-22V-4Al alloy en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, plane bending fatigue tests were conducted on Ti-22V-4Al alloy, a beta-type titanium alloy, to examine the fatigue crack initiation behavior in detail. In addition, the prediction of fatigue crack initiation points was investigated from the perspectives of the Schmidt factor (SF) and crystal plasticity finite element method (CP-FEM). The slip system contributing to fatigue crack initiation can be accurately predicted by assessing the magnitude relationship of SF. Also, this prediction is already indicated in a lot of paper by using out of component of slip activity. However, the location where the fatigue crack will occur can be not estimated by SF on polycrystalline. Therefore, prediction of grains where fatigue cracks will occur could be achieved with high accuracy by constructing a CP-FEM that considers the mechanical interaction of polycrystals and grain boundary. Utilizing advanced methodologies such as CP-FEM and numerical calculation techniques, it is strictly investigated that the factors influencing fatigue crack initiation in polycrystalline materials. Our research concluded the understanding of fatigue crack initiation on polycrystal grains by considering the mechanical interaction of polycrystals and grain boundary. en-copyright= kn-copyright= en-aut-name=ArakawaJinta en-aut-sei=Arakawa en-aut-mei=Jinta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirazumiKoki en-aut-sei=Hirazumi en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UemoriTakeshi en-aut-sei=Uemori en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakemotoYoshito en-aut-sei=Takemoto en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=β-Ti kn-keyword=β-Ti en-keyword=Fatigue crack initiation kn-keyword=Fatigue crack initiation en-keyword=Schmidt factor kn-keyword=Schmidt factor en-keyword=Crystal plasticity FEM kn-keyword=Crystal plasticity FEM en-keyword=Polycrystalline kn-keyword=Polycrystalline END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=5 article-no= start-page=938 end-page=946.e1 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240613 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Virtual indigo carmine chromoendoscopy images: A novel modality for peroral cholangioscopy using artificial intelligence technology (with video) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aims: Accurately diagnosing biliary strictures is crucial for surgical decisions, and although peroral cholangioscopy (POCS) aids in visual diagnosis, diagnosing malignancies or determining lesion margins via this route remains challenging. Indigo carmine is commonly used to evaluate lesions during GI endoscopy. We aimed to establish the utility of virtual indigo carmine chromoendoscopy (VICI) converted from POCS images using artificial intelligence.
Methods: This single-center, retrospective study analyzed 40 patients with biliary strictures who underwent POCS using white-light imaging (WLI) and narrow-band imaging (NBI). A cycle-consistent adversarial network was used to convert the WLI into VICI of POCS images. Three experienced endoscopists evaluated WLI, NBI, and VICI via POCS in all patients. The primary outcome was the visualization quality of surface structures, surface microvessels, and lesion margins. The secondary outcome was diagnostic accuracy.
Results: VICI showed superior visualization of the surface structures and lesion margins compared with WLI (P < .001) and NBI (P < .001). The diagnostic accuracies were 72.5%, 87.5%, and 90.0% in WLI alone, WLI and VICI simultaneously, and WLI and NBI simultaneously, respectively. WLI and VICI simultaneously tended to result in higher accuracy than WLI alone (P = .083), and the results were not significantly different from WLI and NBI simultaneously (P = .65).
Conclusions: VICI in POCS proved valuable for visualizing surface structures and lesion margins and contributed to higher diagnostic accuracy comparable to NBI. In addition to NBI, VICI may be a novel supportive modality for POCS. en-copyright= kn-copyright= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei=

kn-abstract=Periodontal disease is highly prevalent in both humans and dogs. Although there have been reports of cross-infection of periodontopathic bacteria, methods for assessing it have yet to be established. The actual status of cross-infection remains to be seen. The purpose of this study was to evaluate the utility of bacterial DNA and serum immunoglobulin G (IgG) antibody titer assays to assess infection of human-pathogenic and dog-pathogenic Porphyromonas species in dogs. Four experimental beagles were used for establishing methods. Sixty-six companion dogs at veterinary clinics visiting for treatment and prophylaxis of periodontal disease were used and divided into healthy, gingivitis, and periodontitis groups. Periodontal pathogens such as Porphyromonas gingivalis and Porphyromonas gulae were investigated as target bacteria. DNA levels of both bacteria were measured using species-specific primers designed for real-time polymerase chain reaction (PCR). Serum IgG titers of both bacteria were measured by enzyme-linked immunosorbent assay (ELISA).
PCR primers were confirmed to have high sensitivity and specificity. However, there was no relationship between the amount of bacterial DNA and the severity of the periodontal disease. In addition, dogs with periodontitis had higher IgG titers against both bacteria compared to dogs in the healthy and gingivitis groups; there was cross-reactivity between the two bacteria. Receiver operating characteristic (ROC) analysis of IgG titers against both bacteria showed high sensitivity (>90 %) and specificity (>75 %). Since both bacteria were distinguished by DNA assays, the combination of these assays may be useful in the evaluation of cross-infection. en-copyright= kn-copyright= en-aut-name=Tai-TokuzenMasako en-aut-sei=Tai-Tokuzen en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamuraKazuya en-aut-sei=Tamura en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirayamaHaruko en-aut-sei=Hirayama en-aut-mei=Haruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaHirohito en-aut-sei=Ogawa en-aut-mei=Hirohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkuboKeisuke en-aut-sei=Okubo en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MominokiKatsumi en-aut-sei=Mominoki en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Animal Resources, Advanced Science Research Center, Okayama University kn-affil= affil-num=5 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Center for Collaborative Research, Department of Oral Science and Translational Research, Nova Southeastern University kn-affil= affil-num=7 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Comprehensive Dentistry, The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Animal Resources, Advanced Science Research Center, Okayama University kn-affil= affil-num=11 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cross infection kn-keyword=Cross infection en-keyword=Human and dog kn-keyword=Human and dog en-keyword=Periodontal disease kn-keyword=Periodontal disease en-keyword=Porphyromonas gingivalis kn-keyword=Porphyromonas gingivalis en-keyword=Porphyromonas gulae kn-keyword=Porphyromonas gulae en-keyword=Detection assay kn-keyword=Detection assay END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=11 article-no= start-page=2632 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=In Vitro Study of Tumor-Homing Peptide-Modified Magnetic Nanoparticles for Magnetic Hyperthermia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer cells have higher heat sensitivity compared to normal cells; therefore, hyperthermia is a promising approach for cancer therapy because of its ability to selectively kill cancer cells by heating them. However, the specific and rapid heating of tumor tissues remains challenging. This study investigated the potential of magnetic nanoparticles (MNPs) modified with tumor-homing peptides (THPs), specifically PL1 and PL3, for tumor-specific magnetic hyperthermia therapy. The synthesis of THP-modified MNPs involved the attachment of PL1 and PL3 peptides to the surface of the MNPs, which facilitated enhanced tumor cell binding and internalization. Cell specificity studies revealed an increased uptake of PL1- and PL3-MNPs by tumor cells compared to unmodified MNPs, indicating their potential for targeted delivery. In vitro hyperthermia experiments demonstrated the efficacy of PL3-MNPs in inducing tumor cell death when exposed to an alternating magnetic field (AMF). Even without exposure to an AMF, an additional ferroptotic pathway was suggested to be mediated by the nanoparticles. Thus, this study suggests that THP-modified MNPs, particularly PL3-MNPs, hold promise as a targeted approach for tumor-specific magnetic hyperthermia therapy. en-copyright= kn-copyright= en-aut-name=ZhouShengli en-aut-sei=Zhou en-aut-mei=Shengli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsutsumiuchiKaname en-aut-sei=Tsutsumiuchi en-aut-mei=Kaname kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiRitsuko en-aut-sei=Imai en-aut-mei=Ritsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiYukiko en-aut-sei=Miki en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoAnna en-aut-sei=Kondo en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagawaHiroshi en-aut-sei=Nakagawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=3 en-affil=College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=4 en-affil=College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=5 en-affil=College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=6 en-affil=College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=7 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=tumor-homing peptide kn-keyword=tumor-homing peptide en-keyword=magnetic hyperthermia kn-keyword=magnetic hyperthermia en-keyword=magnetic nanoparticles kn-keyword=magnetic nanoparticles en-keyword=ferroptosis kn-keyword=ferroptosis en-keyword=tumor-specific delivery kn-keyword=tumor-specific delivery END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=11 article-no= start-page=5889 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Anti-HMGB1 mAb Therapy Reduces Epidural Hematoma Injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epidural and subdural hematomas are commonly associated with traumatic brain injury. While surgical removal is the primary intervention for these hematomas, it is also critical to prevent and reduce complications such as post-traumatic epilepsy, which may result from inflammatory responses in the injured brain areas. In the present study, we observed that high mobility group box-1 (HMGB1) decreased in the injured brain area beneath the epidural hematoma (EDH) in rats, concurrent with elevated plasma levels of HMGB1. Anti-HMGB1 monoclonal antibody therapy strongly inhibited both HMGB1 release and the subsequent increase in plasma levels. Moreover, this treatment suppressed the up-regulation of inflammatory cytokines and related molecules such as interleukin-1-beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and inducible nitric oxide synthase (iNOS) in the injured areas. Our in vitro experiments using SH-SY5Y demonstrated that hematoma components?thrombin, heme, and ferrous ion? prompted HMGB1 translocation from the nuclei to the cytoplasm, a process inhibited by the addition of the anti-HMGB1 mAb. These findings suggest that anti-HMGB1 mAb treatment not only inhibits HMGB1 translocation but also curtails inflammation in injured areas, thereby protecting the neural tissue. Thus, anti-HMGB1 mAb therapy could serve as a complementary therapy for an EDH before/after surgery. en-copyright= kn-copyright= en-aut-name=GaoShangze en-aut-sei=Gao en-aut-mei=Shangze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangDengli en-aut-sei=Wang en-aut-mei=Dengli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiuKeyue en-aut-sei=Liu en-aut-mei=Keyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomonoYasuko en-aut-sei=Tomono en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FuLi en-aut-sei=Fu en-aut-mei=Li kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GaoYuan en-aut-sei=Gao en-aut-mei=Yuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiYohei en-aut-sei=Takahashi en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YataMariko en-aut-sei=Yata en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Translational Research & Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=epidural hematoma kn-keyword=epidural hematoma en-keyword=HMGB1 kn-keyword=HMGB1 en-keyword=inflammatory response kn-keyword=inflammatory response END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=5938 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Palaeoproteomic investigation of an ancient human skeleton with abnormal deposition of dental calculus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Detailed investigation of extremely severe pathological conditions in ancient human skeletons is important as it could shed light on the breadth of potential interactions between humans and disease etiologies in the past. Here, we applied palaeoproteomics to investigate an ancient human skeletal individual with severe oral pathology, focusing our research on bacterial pathogenic factors and host defense response. This female skeleton, from the Okhotsk period (i.e., fifth to thirteenth century) of Northern Japan, poses relevant amounts of abnormal dental calculus deposition and exhibits oral dysfunction due to severe periodontal disease. A shotgun mass-spectrometry analysis identified 81 human proteins and 15 bacterial proteins from the calculus of the subject. We identified two pathogenic or bioinvasive proteins originating from two of the three "red complex" bacteria, the core species associated with severe periodontal disease in modern humans, as well as two additional bioinvasive proteins of periodontal-associated bacteria. Moreover, we discovered defense response system-associated human proteins, although their proportion was mostly similar to those reported in ancient and modern human individuals with lower calculus deposition. These results suggest that the bacterial etiology was similar and the host defense response was not necessarily more intense in ancient individuals with significant amounts of abnormal dental calculus deposition. en-copyright= kn-copyright= en-aut-name=Uchida-FukuharaYoko en-aut-sei=Uchida-Fukuhara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimamuraShigeru en-aut-sei=Shimamura en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SawafujiRikai en-aut-sei=Sawafuji en-aut-mei=Rikai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiuchiTakumi en-aut-sei=Nishiuchi en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YonedaMinoru en-aut-sei=Yoneda en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshidaHajime en-aut-sei=Ishida en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumuraHirofumi en-aut-sei=Matsumura en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsutayaTakumi en-aut-sei=Tsutaya en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Morphology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Institute for Extra-Cutting-Edge Science and Technology Avant-Garde Research (X-STAR), Japan Agency for Marine-Earth Science and Technology (JAMSTEC) kn-affil= affil-num=3 en-affil=Research Center for Integrative Evolutionary Science, The Graduate University for Advanced Studies (SOKENDAI) kn-affil= affil-num=4 en-affil=Research Center for Experimental Modeling of Human Disease, Kanazawa University kn-affil= affil-num=5 en-affil=The University Museum, The University of Tokyo kn-affil= affil-num=6 en-affil=Department of Human Biology and Anatomy, Graduate School of Medicine, University of the Ryukyus kn-affil= affil-num=7 en-affil=School of Health Sciences, Sapporo Medical University kn-affil= affil-num=8 en-affil=Research Center for Integrative Evolutionary Science, The Graduate University for Advanced Studies (SOKENDAI) kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2024 cd-vols= no-issue= article-no= start-page=6505595 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Circadian Rhythms Fluctuate the Treatment Effects of Intravesical Treatments on Rat Urinary Frequency Models en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives. It is still not clear how the intravesical instillation of drugs affects rat urinary frequency. This study aimed to examine the dynamics of intravesical treatments' treatment effect on rat urinary frequency models by real-time and extended monitoring using a novel continuous urination monitoring system. Methods. Nine eleven-week-old female Wistar rats were divided into three groups to receive intravesical instillation of 0.1% acetic acid (AA), 1.0% AA, or phosphate-buffered saline (PBS). Thirty minutes later, these drugs were voided, and rats were moved to a continuous urination monitoring system, UM-100. UM-100 monitored rat urination quantitatively and continuously for 24 hours. Rats were then euthanized, and histopathologic examinations using a damage score validated the severity of bladder inflammation. We used nine additional rats to determine the treatment effect of various drugs against the urinary frequency. These rats were also treated with 1.0% AA in the same way and divided into three groups (n = 3 each) to receive intravesical instillation of lidocaine, silver nitrate (AgNO3), or dimethyl sulfoxide (DMSO), respectively. Thirty minutes later, rats were catheterized again and moved to the UM-100, and their voiding was monitored for 24 hours. Results. Intravesical instillation of AA increased the urinary frequency and decreased the mean voided volume (VV) in a concentration-dependent manner, with statistical significance at a concentration of 1.0% (urinary frequency; p = 0.0007 , mean VV; p = 0.0032 , respectively) compared with PBS. Histopathological analysis of these models demonstrated a significantly higher damage score of bladder mucosa in both 0.1% AA and 1.0% AA compared with PBS, with the severity in concordance with the clinical severity of urinary frequency (0.1% AA: p < 0.0001 , 1.0% AA: p < 0.0001 ). Moreover, intravesical instillation of lidocaine, AgNO3, and DMSO decreased the urinary frequency. Continuous monitoring with UM-100 also demonstrated that the treatment effect of these intravesically instilled drugs occurred only at night. Conclusions. The extended monitoring of rat urination by UM-100 revealed a significant fluctuation in the treatment effect of intravesically instilled drugs between day and night. These findings may help establish novel therapies for urinary frequency. en-copyright= kn-copyright= en-aut-name=WatanabeTomofumi en-aut-sei=Watanabe en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamaYuki en-aut-sei=Maruyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagasakiNaoya en-aut-sei=Nagasaki en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SekitoTakanori en-aut-sei=Sekito en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EdamuraKohei en-aut-sei=Edamura en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeToyohiko en-aut-sei=Watanabe en-aut-mei=Toyohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue= article-no= start-page=103650 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of cellulose nanofibers on soil water retention and aggregate stability en-subtitle= kn-subtitle= en-abstract= kn-abstract=Innovative solutions that address global challenges such as water scarcity and soil erosion are critical for maintaining sustainable agriculture. Due to their water-absorbing and soil-binding properties, cellulose nanofibers (CNF) can be applied to soil to enhance soil water retention and aggregate stability. In this study, we analyzed the effects of the drying temperature, dosage, irrigation water quality, and soil type on the efficacy of CNFs. Our results revealed that CNF dried at 5 degrees C is more effective at absorbing water than others, and adding 1% CNF enhanced soil water content up to 98%. The CNF samples absorbed water due to their hydrophilic molecular groups and morphological structure, as confirmed by Fourier-transform infrared spectroscopy and scanning electron microscopy. CNF addition increased the soil volumetric water content and prolonged water retention by 22 days in the paddy soil samples, highlighting its potential for drought-prone areas. Furthermore, irrigation water quality, such as pH and cation values, influenced the interactions between CNF and water molecules, suggesting adjustments to the water retention curve. In its hydrated state, CNF promotes colloid flocculation and binds to soil particles, thereby strengthening the bonds crucial for aggregate formation and stability. CNF enhanced macro-aggregate formation by up to 48% and 59% in the masa and paddy soil samples, respectively. Our study emphasizes the potential of CNF for water conservation, soil health, and overall agricultural sustainability. en-copyright= kn-copyright= en-aut-name=NgoAn Thuy en-aut-sei=Ngo en-aut-mei=An Thuy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriYasushi en-aut-sei=Mori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BuiLong Thanh en-aut-sei=Bui en-aut-mei=Long Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Soil amendments kn-keyword=Soil amendments en-keyword=water -saving polymers kn-keyword=water -saving polymers en-keyword=soil moisture improvement kn-keyword=soil moisture improvement en-keyword=mean weight diameter kn-keyword=mean weight diameter en-keyword=irrigation water kn-keyword=irrigation water END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=2 article-no= start-page=86 end-page=96 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spontaneous regression and rare relapse after excisional biopsy in long-term observation of 31 patients with primary conjunctival lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=To elucidate long-term outcome in primary conjunctival lymphoma, a review was conducted of 31 consecutive patients: 21 men and 10 women with an age range of 28 to 85 (median, 61) years at presentation and follow-up periods ranging from 1 to 19 (median, 7) years. Conjunctival lymphoma was on the right side in 10 patients, on the left side in 12, and on both sides in 9. Upper, lower, or both fornix lesions in 28 patients were all diagnosed as extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), while thick nasal bulbar conjunctival lesions in 3 patients were differently diagnosed as MALT lymphoma, diffuse large B-cell lymphoma, and follicular lymphoma, respectively. Seven patients underwent local radiation (30 Gy): as initial treatment in 5 patients and treatment for relapse in 2 patients. The remaining 24 patients were observed without additional treatment after excisional biopsy: 5 of these 24 patients showed relapse 0.5 to 6 years later and underwent excisional biopsy again that revealed MALT lymphoma. Of the 5 patients with relapse, only one with second-time relapse underwent radiation. Fluorodeoxyglucose positron emission tomography was performed in 18 patients and showed no systemic lesions: high uptake was noted in the residual conjunctival lesions of 4 patients and in the relapsed conjunctival lesions of 3 patients. One patient died of rectal cancer while no patients died of lymphoma. Observation is an option in patients with primary conjunctival lymphoma after excisional biopsy. Radiation is a treatment option in the case of relapse. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword= conjunctival lymphoma kn-keyword= conjunctival lymphoma en-keyword=extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) kn-keyword=extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) en-keyword=follicular lymphoma kn-keyword=follicular lymphoma en-keyword=diffuse large B-cell lymphoma kn-keyword=diffuse large B-cell lymphoma en-keyword=fluorodeoxyglucose positron emission tomography (FDG-PET) kn-keyword=fluorodeoxyglucose positron emission tomography (FDG-PET) END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue= article-no= start-page=109565 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical repair for a parahiatal hernia with an esophageal hiatal hernia: A case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction and importance: A parahiatal hernia (PH) is a rare diaphragmatic hernia (DH) adjacent to but separated from the esophageal hiatus. The surgical repair for PH needs primary suture closure or complicated hernioplasty and the addition of an anti-reflux procedure. This report describes a case of PH with a symptomatic esophageal hiatal hernia managed using three-dimensional (3D) laparoscopy.
Case presentation: A 65-year-old woman with back pain and breathlessness was referred to our hospital for a DH. Computed tomography showed a diaphragmatic defect on the left side of the esophageal hiatus. Upper gastrointestinal endoscopy and 24-hour esophageal impedance-pH monitoring showed a symptomatic esophageal hiatal hernia. Laparoscopic repair for both hernias was performed using 3D laparoscopy. The DH orifice was located in the left crus of the diaphragm, and it was separated from the esophageal hiatus. These findings showed that this DH was a PH. The PH was repaired with primary suturing, and a hiatoplasty was performed. Toupet fundoplication was performed with a 270 degrees posterior wrap of the gastric fornix. The patient has remained asymptomatic a year after surgery without any complications.
Clinical discussion: 3D laparoscopy provides significant advantages in surgeries requiring precise suturing. PH repairs require complex procedures, including mesh repair or suturing. Approximately 44 % of PH cases also necessitate fundoplication. 3D laparoscopy was useful for the present case.
Conclusions: A rare PH and a symptomatic type 1 hiatal hernia were repaired with 3D laparoscopy, which is helpful for PH treatment in cases requiring complicated procedures. en-copyright= kn-copyright= en-aut-name=TakahashiYosuke en-aut-sei=Takahashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Parahiatal hernia kn-keyword=Parahiatal hernia en-keyword=Esophageal hiatal hernia kn-keyword=Esophageal hiatal hernia en-keyword=Laparoscopic repair kn-keyword=Laparoscopic repair en-keyword=Three-dimensional laparoscopy kn-keyword=Three-dimensional laparoscopy END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=25 article-no= start-page=12295 end-page=12303 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230620 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Li-Ion Transport and Solution Structure in Sulfolane-Based Localized High-Concentration Electrolytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Localized high-concentration electrolytes (LHCEs), which are mixtures of highly concentrated electrolytes (HCEs) and non-coordinating diluents, have attracted significant interest as promising liquid electrolytes for next-generation Li secondary batteries, owing to their various beneficial properties both in the bulk and at the electrode/electrolyte interface. We previously reported that the large Li+-ion transference number in sulfolane (SL)-based HCEs, attributed to the unique exchange/hopping-like Li+-ion conduction, decreased upon dilution with the non-coordinating hydrofluoroether (HFE) despite the retention of the local Li+-ion coordination structure. Therefore, in this study, we investigated the effects of HFE dilution on the Li+ transference number and the solution structure of SL-based LHCEs via the analysis of dynamic ion correlations and molecular dynamics simulations. The addition of HFE caused nano-segregation in the SL-based LHCEs to afford polar and nonpolar domains and fragmentation of the polar ion-conducting pathway into smaller clusters with increasing HFE content. Analysis of the dynamic ion correlations revealed that the anti-correlated Li+?Li+ motions were more pronounced upon HFE addition, suggesting that the Li+ exchange/hopping conduction is obstructed by the non-ion-conducting HFE-rich domains. Thus, the HFE addition affects the entire solution structure and ion transport without significantly affecting the local Li+-ion coordination structure. Further studies on ion transport in LHCEs would help obtain a design principle for liquid electrolytes with high ionic conductivity and large Li+-ion transference numbers. en-copyright= kn-copyright= en-aut-name=SudohTaku en-aut-sei=Sudoh en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaShuhei en-aut-sei=Ikeda en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigenobuKeisuke en-aut-sei=Shigenobu en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuzukiSeiji en-aut-sei=Tsuzuki en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DokkoKaoru en-aut-sei=Dokko en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WatanabeMasayoshi en-aut-sei=Watanabe en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShinodaWataru en-aut-sei=Shinoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UenoKazuhide en-aut-sei=Ueno en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Taku Sudoh Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=2 en-affil=Department of Materials Chemistry, Nagoya University kn-affil= affil-num=3 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=4 en-affil=Advanced Chemical Energy Research Centre (ACERC), Institute of Advanced Sciences, Yokohama National University kn-affil= affil-num=5 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=6 en-affil=Advanced Chemical Energy Research Centre (ACERC), Institute of Advanced Sciences, Yokohama National University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science and Department of Chemistry, Okayama University kn-affil= affil-num=8 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=120 cd-vols= no-issue=1 article-no= start-page=128 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spontaneous regression of multiple solitary plasmacytoma harboring Epstein?Barr virus: a case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of spontaneous regression (SR) in an elderly untreated patient with multiple solitary plasmacytoma (MSP). Diagnosis of MSP was confirmed through surgical resection of the left nasal cavity mass and subsequent biopsy of the right humerus. The patient was considered ineligible for chemotherapy due to poor performance status. At 3-month post-diagnosis, the patient’s condition worsened with deteriorating bone lesions and emergence of a new serum monoclonal protein. However, these clinical findings completely disappeared at 6 months, and positron emission tomography?computed tomography at 1 year confirmed complete metabolic remission. Notably, peripheral blood lymphocyte counts were inversely correlated with tumor progression and remission. Pathological re-evaluation of the initial biopsy specimens revealed programmed cell death protein 1 (PD-1) expression in tumor-infiltrating CD8+ T cells. In addition, tumor cells were infected with Epstein?Barr virus (EBV) but were negative for programmed cell death ligand 1 (PD-L1) expression, which is the most potent immune escape mechanism in tumor cells. While the mechanism underlying SR remains unclear, our findings suggest that host immune response as well as EBV infection may contribute to SR. Further studies are needed to elucidate the clinicopathologic mechanisms of tumor regression in plasma cell neoplasms. en-copyright= kn-copyright= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiHiroki en-aut-sei=Kobayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NodaMinori en-aut-sei=Noda en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IsekiAkiko en-aut-sei=Iseki en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoYumi en-aut-sei=Sato en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuyamaShoichi en-aut-sei=Kuyama en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Otorhinolaryngology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Pathology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Pathology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=6 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= en-keyword=Plasmacytoma kn-keyword=Plasmacytoma en-keyword=Epstein?Barr virus kn-keyword=Epstein?Barr virus en-keyword=Spontaneous regression kn-keyword=Spontaneous regression END start-ver=1.4 cd-journal=joma no-vol=202 cd-vols= no-issue=3 article-no= start-page=473 end-page=483 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic impact of adjuvant endocrine therapy for estrogen receptor-positive and HER2-negative T1a/bN0M0 breast cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Mammography screening has increased the detection of subcentimeter breast cancers. The prognosis for estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative T1a/bN0M0 breast cancers is excellent; however, the necessity of adjuvant endocrine therapy (ET) is uncertain.
Methods We evaluated the effectiveness of adjuvant ET in patients with ER-positive and HER2-negative T1a/bN0M0 breast cancer who underwent surgery from 2008 to 2012. Standard ET was administrated after surgery. The primary endpoint was the cumulative incidence of distant metastasis. All statistical tests were 2-sided.
Results Adjuvant ET was administered to 3991 (83%) of the 4758 eligible patients (1202 T1a [25.3%] and 3556 T1b [74.7%], diseases). The median follow-up period was 9.2 years. The 9-year cumulative incidence of distant metastasis was 1.5% with ET and 2.6% without ET (adjusted subdistribution hazard ratio [sHR], 0.54; 95% CI, 0.32?0.93). In multivariate analysis, the independent risk factors for distant metastasis were no history of ET, mastectomy, high-grade, and lymphatic invasion. The 9-year overall survival was 97.0% and 94.4% with and without ET, respectively (adjusted HR, 0.57; 95% CI, 0.39?0.83). In addition, adjuvant ET reduced the incidence of ipsilateral and contralateral breast cancer (9-year rates; 1.1% vs. 6.9%; sHR, 0.17, and 1.9% vs. 5.2%; sHR, 0.33).
Conclusions The prognosis was favorable in patients with ER-positive and HER2-negative T1a/bN0M0 breast cancer. Furthermore, adjuvant ET reduced the incidence of distant metastasis with minimal absolute risk difference. These findings support considering the omission of adjuvant ET, especially for patients with low-grade and no lymphatic invasion disease. en-copyright= kn-copyright= en-aut-name=SasadaShinsuke

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast reconstruction (BR) aims to improve the satisfaction and quality of life (QOL) of breast cancer survivors. Clinical studies using patient-reported outcomes (PROs) can therefore provide relevant information to the patients and support decision-making. This scoping review was conducted to analyze recent trends in world regions, methods used, and factors investigated. The literature search was conducted in August 2022. Databases of PubMed, MEDLINE, and CINAHL were searched for relevant English-language studies published from 2017 to 2022. Studies involving women with breast cancer who underwent BR after mastectomy and investigated PROs after BR using BR-specific scales were included. Data on the country, publication year, study design, PRO measures (PROMs) used, time points of surveys, and research themes were collected. In total, 147 articles met the inclusion criteria. BREAST-Q was the most widely used, contributing to the increase in the number and diversification of studies in this area. Such research has been conducted mainly in North America and Europe and is still developing in Asia and other regions. The research themes involved a wide range of clinical and patient factors in addition to surgery, which could be influenced by research methods, time since surgery, and even cultural differences. Recent BR-specific PROMs have led to a worldwide development of research on factors that affect satisfaction and QOL after BR. PRO after BR may be influenced by local cultural and social features, and it would be necessary to accumulate data in each region to draw clinically useful conclusion. en-copyright= kn-copyright= en-aut-name=SaigaMiho en-aut-sei=Saiga en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagiriRyoko en-aut-sei=Nakagiri en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MukaiYuko en-aut-sei=Mukai en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Plastic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Plastic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Patient-reported outcomes kn-keyword=Patient-reported outcomes en-keyword=Breast reconstruction kn-keyword=Breast reconstruction en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Satisfaction kn-keyword=Satisfaction END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=3 article-no= start-page=ezad048 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical outcome of ipsilateral anatomical resection for lung cancer after pulmonary lobectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=OBJECTIVES: Ipsilateral reoperation after pulmonary lobectomy is often challenging because of adhesions from the previous operation. We retrospectively examined the surgical outcome and prognosis of ipsilateral anatomical resection for lung cancer after pulmonary lobectomy using a multicentre database.
METHODS: We evaluated the perioperative outcomes and overall survival of 51 patients who underwent pulmonary lobectomy followed by ipsilateral anatomical resection for lung cancer between January 2012 and December 2018. In addition, patients with stage I non-small-cell lung cancer (NSCLC) were compared with 3411 patients with stage I lung cancer who underwent pulmonary resection without a prior ipsilateral lobectomy.
RESULTS: Ipsilateral anatomical resections included 10 completion pneumonectomies, 19 pulmonary lobectomies and 22 pulmonary segmentectomies. Operative time was 312.2?±?134.5?min, and intraoperative bleeding was 522.2?±?797.5?ml. Intraoperative and postoperative complications occurred in 9 and 15 patients, respectively. However, the 5-year overall survival rate after anatomical resection followed by ipsilateral lobectomy was 83.5%. Furthermore, in patients with c-stage I NSCLC, anatomical resection followed by ipsilateral lobectomy was not associated with worse survival than anatomical resection without prior ipsilateral lobectomy.
CONCLUSIONS: Anatomical resection following ipsilateral lobectomy is associated with a high frequency of intraoperative and postoperative complications. However, the 5-year overall survival in patients with c-stage I NSCLC who underwent ipsilateral anatomical resection after pulmonary lobectomy is comparable to that in patients who underwent anatomical resection without prior pulmonary lobectomy. en-copyright= kn-copyright= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

kn-title=FLOURY ENDOSPERM 6 mutations enhance the sugary phenotype caused by the loss of ISOAMYLASE1 in barley en-subtitle= kn-subtitle= en-abstract= kn-abstract=Starch is a biologically and commercially important glucose polymer synthesized by plants as semicrystalline starch granules (SGs). Because SG morphology affects starch properties, mutants with altered SG morphology may be useful in breeding crops with desirable starch properties, including potentially novel properties. In this study, we employed a simple screen for mutants with altered SG morphology in barley (Hordeum vulgare). We isolated mutants that formed compound SGs together with the normal simple SGs in the endosperm and found that they were allelic mutants of the starch biosynthesis genes ISOAMYLASE1 (HvISA1) and FLOURY ENDOSPERM 6 (HvFLO6), encoding starch debranching enzyme and CARBOHYDRATE-BINDING MODULE 48-containing protein, respectively. We generated the hvflo6 hvisa1 double mutant and showed that it had significantly reduced starch biosynthesis and developed shrunken grains. In contrast to starch, soluble α-glucan, phytoglycogen, and sugars accumulated to higher levels in the double mutant than in the single mutants. In addition, the double mutants showed defects in SG morphology in the endosperm and in the pollen. This novel genetic interaction suggests that hvflo6 acts as an enhancer of the sugary phenotype caused by hvisa1 mutation. en-copyright= kn-copyright= en-aut-name=MatsushimaRyo en-aut-sei=Matsushima en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GalisIvan en-aut-sei=Galis en-aut-mei=Ivan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiuraSatoko en-aut-sei=Miura en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CroftsNaoko en-aut-sei=Crofts en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakenakaYuto en-aut-sei=Takenaka en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OitomeNaoko F. en-aut-sei=Oitome en-aut-mei=Naoko F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshimizuTakeshi en-aut-sei=Ishimizu en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujitaNaoko en-aut-sei=Fujita en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=5 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=6 en-affil=College of Life Sciences, Ritsumeikan University kn-affil= affil-num=7 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=8 en-affil=College of Life Sciences, Ritsumeikan University kn-affil= affil-num=9 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=476 end-page=485 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative and Postoperative Continuous Nutritional Counseling Improves Quality of Life of Gastric Cancer Patient Undergoing?Gastrectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-gastrectomy syndrome (PGS) and body weight loss (BWL) decrease quality of life (QOL) and survival of the patient undergoing gastrectomy. We have introduced perioperative and post-discharge continuous nutritional counseling (CNC) to prevent BWL and improve QOL after gastrectomy. In the present study, we evaluated the effect of CNC on QOL using the Post-gastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Eighty-three patients with gastric cancer (GC) who underwent curative gastrectomy between March 2018 and July 2019 were retrospectively analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n?=?45) or CNC (CNC group, n?=?38) after gastrectomy. QOL at 12?months after gastrectomy was compared between the two groups. In QOL assessment, change in body weight (?7.98% vs. ?12.77%, p?=?0.0057), ingested amount of food per meal (7.00 vs. 6.07, p?=?0.042) and ability for working (1.89 vs. 2.36, p?=?0.049) were significantly better in CNC group than control group. Multiple regression analysis showed that CNC was a significantly beneficial factor for abdominal pain subscale (p?=?0.028), diarrhea subscale (p?=?0.047), ingested amount of food per meal (p?=?0.012), Ability for working (p?=?0.031) and dissatisfaction at the meal (p?=?0.047). Perioperative and postoperative CNC could improve QOL in the patient undergoing gastrectomy in addition to preventing postoperative BWL. en-copyright= kn-copyright= en-aut-name=HanzawaShunya en-aut-sei=Hanzawa en-aut-mei=Shunya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashimaHajime en-aut-sei=Kashima en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiAyako en-aut-sei=Takahashi en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Clinical Nutrition, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Clinical Nutrition, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=185 end-page=191 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduced Immunogenicity of COVID-19 Vaccine in Obese Patients with Type 2 Diabetes: A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The global pandemic of coronavirus infection 2019 (COVID-19) was an unprecedented public health emergency. Several clinical studies reported that heart disease, lung disease, diabetes, hypertension, dyslipidemia, and obesity are critical risk factors for increased severity of and hospitalization for COVID-19. This is largely because patients with these underlying medical conditions can show poor immune responses to the COVID-19 vaccinations. Diabetes is one of the underlying conditions most highly associated with COVID-19 susceptibility and is considered a predictor of poor prognosis of COVID-19. We therefore investigated factors that influence the anti-SARS-CoV-2 spike IgG antibody titer after three doses of vaccination in patients with type 2 diabetes. We found that obesity was associated with low anti-SARS-CoV-2 spike IgG antibody titers following three-dose vaccination in type 2 diabetics. Obese patients with type 2 diabetes may have attenuated vaccine efficacy and require additional vaccination; continuous infection control should be considered in such patients. en-copyright= kn-copyright= en-aut-name=TakahashiHiroko en-aut-sei=Takahashi en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakayamaMasanori en-aut-sei=Nakayama en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Office of Innovative Medicine, Organization for Research Strategy and Development, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=obesity kn-keyword=obesity en-keyword=type 2 diabetes kn-keyword=type 2 diabetes en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=vaccination kn-keyword=vaccination END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=123 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sigle Agent of Posttransplant Cyclophosphamide Without Calcineurin Inhibitor Controls Severity of Experimental Chronic GVHD en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HCT), but its pathogenesis remains unclear. Recently, haplo-identical HCT with post-transplant cyclophosphamide (Haplo-HCT with PTCY) was found to achieve a low incidence rate of acute GVHD and chronic GVHD. However, while the pathogenesis of acute GVHD following Haplo-HCT with PTCY has been well investigated, that of chronic GVHD remains to be elucidated, especially in HLA-matched HCT with PTCY. Based on its safety profile, PTCY is currently applied for the human leucocyte antigen (HLA)-matched HCT setting. Here, we investigated the mechanisms of chronic GVHD following HLA-matched HCT with PTCY using a well-defined mouse chronic GVHD model. PTCY attenuated clinical and pathological chronic GVHD by suppressing effector T-cells and preserving regulatory T-cells compared with a control group. Additionally, we demonstrated that cyclosporine A (CsA) did not show any additional positive effects on attenuation of GVHD in PTCY-treated recipients. These results suggest that monotherapy with PTCY without CsA could be a promising strategy for the prevention of chronic GVHD following HLA-matched HCT. en-copyright= kn-copyright= en-aut-name=SaekiKyosuke en-aut-sei=Saeki en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuroiTaiga en-aut-sei=Kuroi en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=GVHD kn-keyword=GVHD en-keyword=posttransplant cyclophosphamide kn-keyword=posttransplant cyclophosphamide en-keyword=hematopoietic cell transplantation kn-keyword=hematopoietic cell transplantation en-keyword=HLA-identical kn-keyword=HLA-identical END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=2 article-no= start-page=108 end-page=116 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diamond-like carbon coating to inner surface of polyurethane tube reduces Staphylococcus aureus bacterial adhesion and biofilm formation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Staphylococcus aureus is one of the main causative bacteria for polyurethane catheter and artificial graft infection. Recently, we developed a unique technique for coating diamond-like carbon (DLC) inside the luminal resin structure of polyurethane tubes. This study aimed to elucidate the infection-preventing effects of diamond-like carbon (DLC) coating on a polyurethane surface against S. aureus. We applied DLC to polyurethane tubes and rolled polyurethane sheets with our newly developed DLC coating technique for resin tubes. The DLC-coated and uncoated polyurethane surfaces were tested in smoothness, hydrophilicity, zeta-potential, and anti-bacterial properties against S. aureus (biofilm formation and bacterial attachment) by contact with bacterial fluids under static and flow conditions. The DLC-coated polyurethane surface was significantly smoother, more hydrophilic, and had a more negative zeta-potential than did the uncoated polyurethane surface. Upon exposure to bacterial fluid under both static and flow conditions, DLC-coated polyurethane exhibited significantly less biofilm formation than uncoated polyurethane, based on absorbance measurements. In addition, the adherence of S. aureus was significantly lower for DLC-coated polyurethane than for uncoated polyurethane under both conditions, based on scanning electron microscopy. These results show that applying DLC coating to the luminal resin of polyurethane tubes may impart antimicrobial effects against S. aureus to implantable medical polyurethane devices, such as vascular grafts and central venous catheters. en-copyright= kn-copyright= en-aut-name=KuwadaNoriaki en-aut-sei=Kuwada en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiYasuhiro en-aut-sei=Fujii en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakataniTatsuyuki en-aut-sei=Nakatani en-aut-mei=Tatsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OusakaDaiki en-aut-sei=Ousaka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsujiTatsunori en-aut-sei=Tsuji en-aut-mei=Tatsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ImaiYuichi en-aut-sei=Imai en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OozawaSusumu en-aut-sei=Oozawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanemotoKazuo en-aut-sei=Tanemoto en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Institute of Frontier Science and Technology, Okayama University of Science kn-affil= affil-num=4 en-affil=Department of Pharmacology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Institute of Frontier Science and Technology, Okayama University of Science kn-affil= affil-num=7 en-affil=Division of Cardiovascular Surgery, Department of Surgery, Labatt Family Heart Centre, The Hospital for Sick Children, University of Toronto kn-affil= affil-num=8 en-affil=Division of Medical Safety Management, Safety Management Facility, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Surgery, Kawasaki Medical School kn-affil= en-keyword=Diamond-like carbon kn-keyword=Diamond-like carbon en-keyword=Polyurethanes kn-keyword=Polyurethanes en-keyword=Luminal coating kn-keyword=Luminal coating en-keyword=Staphylococcus aureus kn-keyword=Staphylococcus aureus en-keyword=Prevention of infection kn-keyword=Prevention of infection END start-ver=1.4 cd-journal=joma no-vol=143 cd-vols= no-issue= article-no= start-page=110894 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First-principles molecular dynamics simulations for the properties of boron-doped tetrahedral amorphous carbon en-subtitle= kn-subtitle= en-abstract= kn-abstract=Based on first-principles molecular dynamics (FPMD) simulations combined with a liquid quenching method, we study the effects of boron doping at 0 %, 2 %, 4 %, 6 % on the properties of tetrahedral amorphous carbon (ta-C) with an initial density of 3.0 g/cm3. The results of bond structures and internal stress show the promotion of graphitization with increase in the concentration of boron doping. In addition, simulation of electronic states reveals that the Fermi level shifts to valence band and the intensity of density of electronic states near Fermi level increases with the boron concentration increasing. A covalent bond formation between carbon and boron atoms is also shown by analyzing projected densities of electronic states (PDOS) and electron density distribution. The results of electronic state and bond formation strongly indicate that the boron-doped ta-C is like a p-type semiconductor. The present simulation results provide useful information for deeper understanding on the physical properties of boron-doped ta-C. en-copyright= kn-copyright= en-aut-name=YueQiang en-aut-sei=Yue en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Boron-doped tetrahedral amorphous carbon kn-keyword=Boron-doped tetrahedral amorphous carbon en-keyword=First-principles molecular dynamics kn-keyword=First-principles molecular dynamics en-keyword=Liquid quenching method kn-keyword=Liquid quenching method END start-ver=1.4 cd-journal=joma no-vol=965 cd-vols= no-issue=1 article-no= start-page=91 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supernova Burst and Diffuse Supernova Neutrino Background Simulator for Water Cherenkov Detectors en-subtitle= kn-subtitle= en-abstract= kn-abstract=If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations. In addition, there is anticipation that observation of the diffuse supernova neutrino background will yield discoveries in the near future, given that experimental upper limits are approaching theoretical predictions. We have developed a new supernova event simulator for water Cherenkov neutrino detectors, such as the highly sensitive Super-Kamiokande. This simulator calculates the neutrino interaction in water for two simulation purposes, individual core-collapse supernova bursts and diffuse supernova neutrino background. Based on this simulator, we can evaluate the precision in determining the location of supernovae and estimate the expected number of events related to the diffuse supernova neutrino background in Super-Kamiokande. In this paper, we describe the basic structure of the simulator and its demonstration. en-copyright= kn-copyright= en-aut-name=NakanishiFumi en-aut-sei=Nakanishi en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IzumiyamaShota en-aut-sei=Izumiyama en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaMasayuki en-aut-sei=Harada en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Tokyo Institute of Technology kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1381083 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240326 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trends of correlations between serum levels of growth hormone and insulin-like growth factor-I in general practice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum levels of growth hormone (GH) and insulin-like growth factor (IGF)-I are crucial in the diagnosis and management of GH-related diseases. However, these levels are affected by nutritional and metabolic status. To elucidate the correlations between GH and IGF-I in various conditions, a retrospective analysis was performed for adult patients in which GH levels were examined by general practitioners during the period from January 2019 to December 2021. Of 642 patients, 33 patients were diagnosed with acromegaly, 21 were diagnosed with GH deficiency (GHD), and 588 were diagnosed with non-GH-related diseases (NGRD). In contrast to the positive correlations found between the levels of GH and IGF-I in patients with acromegaly (R=0.50; P<0.001) and patients with GHD (R=0.39; P=0.08), a negative correlation was found in the NGRD group (R=-0.23; P<0.001). In that group, the results of multivariable analysis showed that GH levels were predominantly influenced by gender and body mass index (BMI), whereas IGF-I levels were modulated by albumin in addition to age and GH. Of note, in the NGRD group, there was an enhanced negative correlation between GH and IGF-I under conditions of BMI < 22 and albumin < 4.0 g/dL (R=-0.45; P<0.001), and the negative correlation between GH and IGF-I was reinforced by excluding patients with other pituitary diseases and patients taking oral steroids (R=-0.51; P<0.001 and R=-0.59; P<0.001, respectively). Collectively, the results indicate that attention should be given to the presence of a negative correlation between serum levels of GH and IGF-I, especially in lean and low-nutritious conditions. en-copyright= kn-copyright= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuyamaAtsuhito en-aut-sei=Suyama en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YasudaMiho en-aut-sei=Yasuda en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=acromegaly kn-keyword=acromegaly en-keyword=growth hormone (GH) kn-keyword=growth hormone (GH) en-keyword=GH deficiency (GHD) kn-keyword=GH deficiency (GHD) en-keyword=insulin-like growth factor (IGF)-I kn-keyword=insulin-like growth factor (IGF)-I en-keyword=pituitary gland kn-keyword=pituitary gland END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=4953 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term monitoring of gastric mucosa-associated lymphoid tissue lymphoma in patients with extra copies of the MALT1 gene en-subtitle= kn-subtitle= en-abstract= kn-abstract=The objective of this study was to clarify the long-term prognosis of patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma with additional copies of MALT1. In this multicenter retrospective study, we enrolled 145 patients with gastric MALT lymphoma who underwent fluorescence in situ hybridization (FISH) analysis to detect t(11;18) translocation. The patient cohort was divided into three groups: Group A (n?=?87), comprising individuals devoid of the t(11;18) translocation or extra MALT1 copies; Group B (n?=?27), encompassing patients characterized by the presence of the t(11;18) translocation; and Group C (n?=?31), including patients with extra MALT1 copies. The clinical outcomes in each cohort were collected. Over the course of a mean follow-up of 8.5?±?4.2 years, one patient died of progressive MALT lymphoma, while 15 patients died due to etiologies unrelated to lymphoma. The progression or relapse of MALT lymphoma was observed in 11 patients: three in Group A, two in Group B, and six in Group C. In Groups A, B, and C, the 10-year overall survival rates were 82.5%, 93.8%, and 86.4%, respectively, and the 10-year event-free survival rates were 96.1%, 96.0%, and 82.9%, respectively. The event-free survival rate in Group C was significantly lower than that in Group A. However, no differences were observed in the 10-year event-free survival rates among individuals limited to stage I or II1 disease (equivalent to excluding patients with stage IV disease in this study, as there were no patients with stage II2), with rates of 98.6%, 95.8%, and 92.3% for Groups A, B, and C, respectively. In conclusion, the presence of extra copies of MALT1 was identified as an inferior prognostic determinant of event-free survival. Consequently, trisomy/tetrasomy 18 may serve as an indicator of progression and refractoriness to therapeutic intervention in patients with gastric MALT lymphoma, particularly stage IV gastric MALT lymphoma. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyaharaKoji en-aut-sei=Miyahara en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiokaMasao en-aut-sei=Yoshioka en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaguchiChihiro en-aut-sei=Sakaguchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoKumiko en-aut-sei=Yamamoto en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiYoshinari en-aut-sei=Kawai en-aut-mei=Yoshinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil= Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Hiroshima City Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Mitoyo General Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Onomichi Municipal Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Fukuyama Medical Center kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue kn-keyword=Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue en-keyword=Gastric neoplasms kn-keyword=Gastric neoplasms en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=t(11;18) translocation, kn-keyword=t(11;18) translocation, en-keyword=Trisomy 18 kn-keyword=Trisomy 18 END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=4564 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Longitudinal antibody dynamics after COVID-19 vaccine boosters based on prior infection status and booster doses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Global concern over COVID-19 vaccine distribution disparities highlights the need for strategic booster shots.

Prior infection enhanced post-booster immunity (posterior median 0.346, 95% credible interval [CrI] 0.335-0.355), maintaining antibody levels (posterior median 0.021; 95% CrI 0.019-0.023) over 1 year, in contrast to uninfected individuals whose levels had waned by 8 months post-vaccination. Each additional booster was correlated with higher baseline antibody levels and slower declines, comparing after the third dose. Female sex, older age, immunosuppressive status, and smoking history were associated with lower baseline post-vaccination antibodies, but not associated with decline rates except for older age in the main model. Prior infection status and tailored, efficient, personalized booster strategies are crucial, considering sex, age, health conditions, and lifestyle. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiAyako en-aut-sei=Sasaki en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=rbac088 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fabrication of initial trabecular bone-inspired three-dimensional structure with cell membrane nano fragments en-subtitle= kn-subtitle= en-abstract= kn-abstract=The extracellular matrix of trabecular bone has a large surface exposed to the bone marrow and plays important roles such as hematopoietic stem cell niche formation and maintenance. In vitro reproduction of trabecular bone microenvironment would be valuable not only for developing a functional scaffold for bone marrow tissue engineering but also for understanding its biological functions. Herein, we analyzed and reproduced the initial stages of trabecular bone formation in mouse femur epiphysis. We identified that the trabecular bone formation progressed through the following steps: (i) partial rupture of hypertrophic chondrocytes; (ii) calcospherite formation on cell membrane nano fragments (CNFs) derived from the ruptured cells; and (iii) calcospherite growth and fusion to form the initial three-dimensional (3D) structure of trabecular bones. For reproducing the initial trabecular bone formation in vitro, we collected CNFs from cultured cells and used as nucleation sites for biomimetic calcospherite formation. Strikingly, almost the same 3D structure of the initial trabecular bone could be obtained in vitro by using additional CNFs as a binder to fuse biomimetic calcospherites. en-copyright= kn-copyright= en-aut-name=KadoyaKoichi en-aut-sei=Kadoya en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiaoYu Yang en-aut-sei=Jiao en-aut-mei=Yu Yang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoTakayoshi en-aut-sei=Nakano en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiAkira en-aut-sei=Sasaki en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Division of Materials & Manufacturing Science, Osaka University kn-affil= affil-num=6 en-affil=Department of Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=trabecular bone kn-keyword=trabecular bone en-keyword=calcospherites kn-keyword=calcospherites en-keyword=cell membrane nano fragments kn-keyword=cell membrane nano fragments en-keyword=three dimensionalization kn-keyword=three dimensionalization en-keyword=bone tissue synthesis kn-keyword=bone tissue synthesis END start-ver=1.4 cd-journal=joma no-vol=564 cd-vols= no-issue= article-no= start-page=121937 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and characterization of iron(II) complex with unsymmetrical heterocyclic (2-pyridyl)(4-imidazolyl)azine en-subtitle= kn-subtitle= en-abstract= kn-abstract=A new iron(II) complex bearing unsymmetrical azine, [Fe(HLH)2](PF6)2?H2O?MeCN (HLH = 2-pyridylmethylidenehydrazono(4-imidazolyl)methane), was synthesized exclusively by a reaction of 2-pyridine carboxaldehyde, 1H-imidazole-4-carboxaldehyde, hydrazine monohydrate and FeCl2?4H2O (in a molar ratio of 2:2:2:1) in methanol, followed by the addition of an aqueous NH4PF6 solution. It was characterized using spectroscopic techniques, elemental analysis, magnetic measurement, and cyclic voltammetry. The molecular and crystal structure of the compound was revealed by X-ray analysis, where an iron(II) ion was surrounded by two HLH azines with a planar E(py),Z(im) conformation, and tridentate κ3N,N’,N” coordination mode, forming a monomeric six-coordinated and diamagnetic complex. The complex cations were linked by water molecules via intermolecular hydrogen-bonding interactions between the imidazole N?H and the neighboring uncoordinated azine-N atom, forming a 1D chain structure. The selective formation of this unsymmetrical azine (HLH) from a stoichiometric mixture of the components would result from the steric preference of the five- and six-membered chelate rings by the 2-pyridyl and 4-imidazolyl azine moieties, respectively, with the E(py),Z(im) configuration. en-copyright= kn-copyright= en-aut-name=HayiborKennedy Mawunya en-aut-sei=Hayibor en-aut-mei=Kennedy Mawunya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SunatsukiYukinari en-aut-sei=Sunatsuki en-aut-mei=Yukinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiTakayoshi en-aut-sei=Suzuki en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= en-keyword=(Pyridyl)(imidazolyl)azine kn-keyword=(Pyridyl)(imidazolyl)azine en-keyword=Aldazines kn-keyword=Aldazines en-keyword=Iron(II) complex kn-keyword=Iron(II) complex en-keyword=Crystal structure kn-keyword=Crystal structure END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Support for Sexual Minorities by Specialized Support Departments at Foreign Universities: Survey of Universities in the U.S.A. and Canada kn-title=海外の大学の専門支援部署によるセクシュアルマイノリティ支援−アメリカとカナダの大学への調査− en-subtitle= kn-subtitle= en-abstract=A survey was conducted among universities in the U.S.A. and Canada that have specialized support departments for sexual minority students regarding their support systems and support status. 22 universities responded to the survey.

Regarding the qualifications of staff members, in addition to their degrees and names of qualifications, being a sexual minority or having support experience were mentioned. All universities offered "organizing events" and "lending relevant materials". Many of the universities offered more support resources, such as holding events and training volunteers, than individual specialized support for sexual minorities.

This level is an isomeric state with a long radiative lifetime. Therefore, 229Th can be excited to the isomeric state using a vacuum ultraviolet laser and is expected to have applications such as in frequency standards. Our group has been conducting experiments to excite 229Th to the isomeric state via the second excited state using the high-intensity X-ray beam available at the SPring-8 facility. To detect vacuum ultraviolet photons from the isomeric state of 229Th, a dedicated apparatus was constructed. We employed 229Th-doped CaF2 crystals as the irradiation target. Because these targets emit numerous scintillation photons due to nuclear decay and X-ray beam irradiation, detectors are required to significantly reduce these background events. To achieve this, we adopted dichroic mirrors and a photomultiplier tube for detecting scintillation photons by nuclear decay, in addition to a solar-blind photomultiplier tube for detecting decay photons from the isomeric state of 229Th. In this proceedings paper, we describe the experimental apparatus used in the beamtime in 2023. en-copyright= kn-copyright= en-aut-name=HirakiTakahiro en-aut-sei=Hiraki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=229Th kn-keyword=229Th en-keyword=Isomeric state kn-keyword=Isomeric state en-keyword=Vacuum ultraviolet light kn-keyword=Vacuum ultraviolet light en-keyword=X-ray beam kn-keyword=X-ray beam en-keyword=SPring-8 kn-keyword=SPring-8 en-keyword=Detector kn-keyword=Detector END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue= article-no= start-page=41 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study on the Relationship between Self-Efficacy, Social Skills, and EI in Career Choice―Based on Three Years of College Student Data During the Corona Crisis― kn-title=進路選択における自己効力感、ソーシャルスキル、EIの関係に関する考察―コロナ禍における3年間の大学生データを基にして― en-subtitle= kn-subtitle= en-abstract=Previous research on career selection has reported a variety of research results, such as increasing career choice ability, which activates career choice behavior, and mediated by career choice self-efficacy, which further increases career choice behavior(Tominaga, 2009).

As a result of the survey, it was revealed that the perspective of social studies held by rookie elementary school teachers is in the process of forming their own view of social studies while filling in the gaps through encountering new experiences and values, such as observing children in daily classes, researching teaching materials, and experiencing student guidance, based on what they learned in the seminar they belonged to in order to write their graduation thesis in college. In addition, with regard to the image of children that they want to nurture through social studies, teachers' aspirations for a better future society are at the core of their thinking about the role of social studies, and they recognize that social studies is a subject that is closely related to student guidance and life guidance. kn-abstract= 本研究は,初任期の小学校教師が何を拠り所として社会科観を形成しているのか,また自身の社会科観をどのように発展させていこうとしているのかを明らかにしようとするものである。調査の結果,初任期小学校教師は,大学時代の卒業論文を書くために所属したゼミでの学びが核となり,日々の授業での子供観察や教材研究,生徒指導の経験など,新しい経験や価値観に出会うことを通して不足している部分を補いながら自身の社会科観を形成しており,社会科観は流動的であることが明らかになった。また,社会科を通して育てたい子供像については,教師のよりよい未来社会への志向が,社会科の役割に対する考えの核となっており,社会科を生徒指導や生活指導と密接に関連する教科であると認識していた。 en-copyright= kn-copyright= en-aut-name=FUKUTAYuka en-aut-sei=FUKUTA en-aut-mei=Yuka kn-aut-name=福田友香 kn-aut-sei=福田 kn-aut-mei=友香 aut-affil-num=1 ORCID= en-aut-name=KUWABARAToshinori en-aut-sei=KUWABARA en-aut-mei=Toshinori kn-aut-name=桑原敏典 kn-aut-sei=桑原 kn-aut-mei=敏典 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=小学校教師 (elementary school teacher) kn-keyword=小学校教師 (elementary school teacher) en-keyword=社会科観 (social studies perspectives) kn-keyword=社会科観 (social studies perspectives) en-keyword=インタビュー (interview) kn-keyword=インタビュー (interview) en-keyword=初任期教師 (rookie teacher) kn-keyword=初任期教師 (rookie teacher) en-keyword=教師のゲートキーピング (gatekeeping role of teacher) kn-keyword=教師のゲートキーピング (gatekeeping role of teacher) END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=87 end-page=101 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Introduction and Effective Use of Individualized Education Program of Learning in Regular Class (LRC) in China kn-title=中華人民共和国の随班就読における個別化教育計画の導入と効果的な活用方策 en-subtitle= kn-subtitle= en-abstract=The purpose of this study is to clarify the issues for the preparation and effective use of individualized education program (IEP) in Learning in Regular Class (LRC), and to propose improvement measures.

The difficulties in preparing an IEP were the following: (1) issues related to the LRC policy, (2) issues related to cooperation with parents, (3) practical issues for teachers in preparing an IEP. In response to these issues, it is necessary to formulate detailed legal regulations on LRC, clarify how to deal with students with disabilities after their admission. Efforts from schools and parents are indispensable. In addition, it is necessary to increase the awareness of IEP and the rate of formulation and providing support from various fields in preparation of IEP. In addition, it was important that there is not enough just to create a plan, but how to utilize it. kn-abstract= 本研究では,随班就読における個別化教育計画の作成及び効果的な活用に向けた課題を明らかにし,改善策を提言することを目的とした。随班就読の担当経験のある小中学校の教員(5名)を対象にインタビュー調査を行った。M-GTA に基づく質的分析の結果,個別化教育計画の作成のための困難は,【随班就読政策に関する課題】【保護者との連携の課題】【個別化教育計画の作成における教員の実践的課題】に分類できた。これらの課題の改善のためには,随班就読に関する詳細で実質的な法律上の規定を整備し,障害のある児童生徒を受け入れた後の対応の仕組みを明確にする必要がある。また,個別化教育計画の認知度及び作成率を高め,作成に当たっての連携が重要になる。とくに,計画の作成にとどまらず,その活用法が重要であり,計画の有効性を評価する仕組みづくりが不可欠である。 en-copyright= kn-copyright= en-aut-name=HUJueying en-aut-sei=HU en-aut-mei=Jueying kn-aut-name=胡?穎 kn-aut-sei=胡 kn-aut-mei=?穎 aut-affil-num=1 ORCID= en-aut-name=YOSHITOSHIMunehisa en-aut-sei=YOSHITOSHI en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=2 ORCID= affil-num=1 en-affil=Student at the Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=中華人民共和国 (People's Republic of China) kn-keyword=中華人民共和国 (People's Republic of China) en-keyword=随班就読 (Learning in Regular Class (LRC)) kn-keyword=随班就読 (Learning in Regular Class (LRC)) en-keyword=個別化教育計画 (Individualized Education Program) kn-keyword=個別化教育計画 (Individualized Education Program) END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=11 article-no= start-page=e0295078 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between oral condition and subjective psychological well-being among older adults attending a university hospital dental clinic: A cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Positive psychological well-being has a favorable impact on survival rates in both healthy and unhealthy populations. Oral health is also associated with psychological well-being, is multidimensional in nature, and includes physical, psychological, emotional, and social domains that are integral to overall health and well-being. This study aimed to identify the associations between individual and environmental characteristics, oral condition and nutritional status in relation to subjective well-being among older adults using the Wilson and Cleary conceptual model. The participants were older adults (age >= 60 years) attending a university hospital. Subjective well-being was assessed using the World Health Organization-5 Well-Being Index, oral condition was assessed based on the number of bacteria in the tongue coating, oral wettability, tongue pressure, occlusal force, oral diadochokinesis, and masticatory ability, and subjective swallowing function was assessed using the Eating Assessment Tool, number of remaining teeth, and number of functional teeth. In addition, factors related to well-being, including social networks, life-space mobility, nutritional status, smoking history, drinking history, and medical history were assessed. In the analysis, structural equation modeling was used to investigate the association between oral condition and subjective well-being. Confirmatory factor analysis revealed oral condition as a latent variable, including tongue pressure, oral diadochokinesis /pa/, /ta/, /ka/, occlusal force, masticatory ability, subjective swallowing function, and number of functional teeth. Structural Equation Modeling revealed that oral condition was positively correlated with nutritional status, and nutritional status was positively correlated with the World Health Organization-5 Well-Being Index. These findings suggest that oral condition may influence subjective well-being via nutritional status or social environmental factors. en-copyright= kn-copyright= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Health, Takarazuka University of Medical and Health Care kn-affil= END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=11 article-no= start-page=4993 end-page=5001 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multimodal Prediction of Cervical Lymph Node Metastasis and Recurrence in Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Oral squamous cell carcinoma (OSCC) is the most common malignancy in the head/neck region, and cervical lymph node (CLN) metastasis is a strong poor-prognosis factor. In addition, many patients with OSCC experience recurrence despite multidisciplinary treatment. We sought to identify factors associated with CLN metastasis and recurrence in patients with OSCC. Patients and Methods: We evaluated a total of 45 patients and 233 target CLNs. The longest diameter of the target CLN, the shortest diameter of the target CLN (LS), the area of the target CLN, and the relative computed tomography (CT) values of the target CLNs calculated based on the CT values of the internal jugular vein (LCT) were obtained from preoperative CT images, and the maximum standardized uptake values of the primary tumor (pSUV) and target CLN (nSUV) were obtained from preoperative 18F-fluorodeoxyglucose-positron emission tomography/CT images. We performed immunohistochemical staining for cytokeratin 13 (CK13) and 17 (CK17) on neck dissection tissues. Results: A discrimination equation was used that can predict CLN metastasis with a 92.2% discrimination rate using LS, LCT, pSUV, and nSUV. The CLNs were divided into discrimination and non-discrimination groups based on discriminant equations and CK13 and CK17 were used as the objective variables. A significantly higher recurrence rate was observed in the non-discrimination group (CK13: 5-year recurrence rate 28.6% vs. 64.3%, p<0.01; CK17: 5-year recurrence rate 28.0% vs. 76.0%, p<0.01). Conclusion: CLN metastases in OSCC can be assessed by combining preoperative imaging. The combined use of CK13 and CK17 expression with imaging findings offers an integrated approach to predict OSCC recurrence. en-copyright= kn-copyright= en-aut-name=KANEMOTOHIDEKA en-aut-sei=KANEMOTO en-aut-mei=HIDEKA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OBATAKYOICHI en-aut-sei=OBATA en-aut-mei=KYOICHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UMEMORIKOKI en-aut-sei=UMEMORI en-aut-mei=KOKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HASEGAWAKAZUAKI en-aut-sei=HASEGAWA en-aut-mei=KAZUAKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ONOSAWAKO en-aut-sei=ONO en-aut-mei=SAWAKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ONOKISHO en-aut-sei=ONO en-aut-mei=KISHO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YUTORIHIROKAZU en-aut-sei=YUTORI en-aut-mei=HIROKAZU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IBARAGISOICHIRO en-aut-sei=IBARAGI en-aut-mei=SOICHIRO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Oral cancer kn-keyword=Oral cancer en-keyword=head and neck squamous cell carcinoma kn-keyword=head and neck squamous cell carcinoma en-keyword=neck dissection kn-keyword=neck dissection en-keyword=lymph node kn-keyword=lymph node en-keyword=discriminant analysis kn-keyword=discriminant analysis en-keyword=cytokeratin kn-keyword=cytokeratin END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=31 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exploratory study of volatile fatty acids and the rumen-and-gut microbiota of dairy cows in a single farm, with respect to subclinical infection with bovine leukemia virus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Subclinical infection with bovine leukemia virus (BLV) in cows can cause economic losses in milk and meat production in many countries, as BLV-related negative effects. The volatile fatty acids (VFAs) and microbiota present in the digestive tracts of cows can contribute to cow health. Here, we exploratorily investigated the VFAs and microbiota in the rumen and gut with respect to subclinical BLV infection using cows housed at a single farm.
Results We analyzed a herd of 38 cows kept at one farm, which included 15 uninfected and 23 BLV-infected cows. First, the analysis of the VFAs in the rumen, gut, and blood revealed an absence of statistically significant differences between the uninfected and BLV-infected groups. Thus, BLV infection did not cause major changes in VFA levels in all tested specimens. Next, we analyzed the rumen and gut microbiota. The analysis of the microbial diversity revealed a modest difference between the uninfected and BLV-infected groups in the gut; by contrast, no differences were observed in the rumen. In addition, the investigation of the bacteria that were predominant in the uninfected and BLV-infected groups via a differential abundance analysis showed that no significant bacteria were present in either of the microbiota. Thus, BLV infection possibly affected the gut microbiota to a small extent. Moreover, bacterial associations were compared between the uninfected and BLV-infected groups. The results of this analysis suggested that BLV infection affected the equilibrium of the bacterial associations in both microbiota, which might be related to the BLV-related negative effects. Thus, BLV infection may negatively affect the equilibrium of bacterial associations in both microbiota.
Conclusions Subclinical BLV infection is likely to affect the rumen and gut microbiota, which may partly explain the BLV-related negative effects. en-copyright= kn-copyright= en-aut-name=SuzukiTakehito en-aut-sei=Suzuki en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiHironobu en-aut-sei=Murakami en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoReiichiro en-aut-sei=Sato en-aut-mei=Reiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Takemura-UchiyamaIyo en-aut-sei=Takemura-Uchiyama en-aut-mei=Iyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgataMasaya en-aut-sei=Ogata en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SogawaKazuyuki en-aut-sei=Sogawa en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshidaHiroho en-aut-sei=Ishida en-aut-mei=Hiroho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AtipairinApichart en-aut-sei=Atipairin en-aut-mei=Apichart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagaiMakoto en-aut-sei=Nagai en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=2 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=3 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Agriculture, University of Miyazaki kn-affil= affil-num=5 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=7 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=8 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=9 en-affil=School of Pharmacy, Walailak University kn-affil= affil-num=10 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=School of Veterinary Medicine, Azabu University kn-affil= en-keyword=Bovine leukemia virus kn-keyword=Bovine leukemia virus en-keyword=Volatile fatty acids kn-keyword=Volatile fatty acids en-keyword=Rumen kn-keyword=Rumen en-keyword=Gut, Microbiota kn-keyword=Gut, Microbiota en-keyword=Cows kn-keyword=Cows END start-ver=1.4 cd-journal=joma no-vol=299 cd-vols= no-issue=8 article-no= start-page=105020 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mammalian type opsin 5 preferentially activates G14 in Gq-type G proteins triggering intracellular calcium response en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mammalian type opsin 5 (Opn5m), a UV-sensitive G protein-coupled receptor opsin highly conserved in vertebrates, would provide a common basis for UV sensing from lamprey to humans. However, G protein coupled with Opn5m remains controversial due to variations in assay conditions and the origin of Opn5m across different reports. Here, we examined Opn5m from diverse species using an aequorin luminescence assay and G alpha-KO cell line. Beyond the commonly studied major G alpha classes, G alpha q, G alpha 11, G alpha 14, and G alpha 15 in the Gq class were individually investigated in this study, as they can drive distinct signaling pathways in addition to a canonical calcium response. UV light triggered a calcium response via all the tested Opn5m proteins in 293T cells, which was abolished by Gq-type G alpha deletion and rescued by cotransfection with mouse and medaka Gq-type G alpha proteins. Opn5m preferentially activated G alpha 14 and close relatives. Mutational analysis implicated specific regions, including alpha 3-beta 5 and alpha G-alpha 4 loops, alpha G and alpha 4 helices, and the extreme C terminus, in the preferential activation of G alpha 14 by Opn5m. FISH revealed co-expression of genes encoding Opn5m and G alpha 14 in the scleral cartilage of medaka and chicken eyes, supporting their physiological coupling. This suggests that the preferential activation of G alpha 14 by Opn5m is relevant for UV sensing in specific cell types. en-copyright= kn-copyright= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaTakahiro en-aut-sei=Yamashita en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biophysics, Graduate School of Science, Kyoto University kn-affil= affil-num=3 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=G protein kn-keyword=G protein en-keyword=G protein?coupled receptor (GPCR) kn-keyword=G protein?coupled receptor (GPCR) en-keyword=photoreceptor kn-keyword=photoreceptor en-keyword=rhodopsin kn-keyword=rhodopsin en-keyword=calcium intracellular release kn-keyword=calcium intracellular release en-keyword=protein?protein interaction kn-keyword=protein?protein interaction en-keyword=signal transduction kn-keyword=signal transduction en-keyword=nonvisual photoreception kn-keyword=nonvisual photoreception END start-ver=1.4 cd-journal=joma no-vol=299 cd-vols= no-issue=7 article-no= start-page=104839 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural insights into the action mechanisms of artificial electron acceptors in photosystem II en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) utilizes light energy to split water, and the electrons extracted from water are transferred to QB, a plastoquinone molecule bound to the D1 subunit of PSII. Many artificial electron acceptors (AEAs) with molecular structures similar to that of plastoquinone can accept electrons from PSII. However, the molecular mechanism by which AEAs act on PSII is unclear. Here, we solved the crystal structure of PSII treated with three different AEAs, 2,5-dibromo-1,4-benzoquinone, 2,6dichloro-1,4-benzoquinone, and 2-phenyl-1,4-benzoquinone, at 1.95 to 2.10 angstrom resolution. Our results show that all AEAs substitute for QB and are bound to the QB-binding site (QB site) to receive electrons, but their binding strengths are different, resulting in differences in their efficiencies to accept electrons. The acceptor 2-phenyl-1,4-benzoquinone binds most weakly to the QB site and showed the highest oxygen-evolving activity, implying a reverse relationship between the binding strength and oxygen-evolving activity. In addition, a novel quinonebinding site, designated the QD site, was discovered, which is located in the vicinity of QB site and close to QC site, a binding site reported previously. This QD site is expected to play a role as a channel or a storage site for quinones to be transported to the QB site. These results provide the structural basis for elucidating the actions of AEAs and exchange mechanism of QB in PSII and also provide information for the design of more efficient electron acceptors. en-copyright= kn-copyright= en-aut-name=KamadaShinji en-aut-sei=Kamada en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=electron transfer kn-keyword=electron transfer en-keyword=structural biology kn-keyword=structural biology en-keyword=crystal structure kn-keyword=crystal structure en-keyword=electron acceptor kn-keyword=electron acceptor END start-ver=1.4 cd-journal=joma no-vol=150 cd-vols= no-issue=2 article-no= start-page=89 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical characteristics of patients treated with immune checkpoint inhibitors in EGFR-mutant non-small cell lung cancer: CS-Lung-003 prospective observational registry study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Immune checkpoint inhibitors (ICIs) are ineffective against epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC). This study aimed to investigate the clinical characteristics of patients who were treated or not treated with ICIs, and of those who benefit from immunotherapy in EGFR-mutant NSCLC.
Methods We analyzed patients with unresectable stage III/IV or recurrent NSCLC harboring EGFR mutations using a prospective umbrella-type lung cancer registry (CS-Lung-003).
Results A total of 303 patients who met the eligibility criteria were analyzed. The median age was 69 years; 116 patients were male, 289 had adenocarcinoma, 273 had major mutations, and 67 were treated with ICIs. The duration of EGFR-TKI treatment was longer in the Non-ICI group than in the ICI group (17.1 vs. 12.7 months, p? Conclusion ICIs were administered to only 22% of patients with EGFR-mutated lung cancer, and they had shorter TTNT of EGFR-TKI compared to other patients. ICI treatment should be avoided in EGFR mutated lung cancer with poor PS but can be considered for lung cancer with EGFR minor mutations. Pathological biomarker to predict long-term responders to ICI are needed.

kn-subject= en-title= kn-title=The first presentation of a case of nail-patella syndrome newly diagnosed at the onset of rheumatoid arthritis: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Nail-patella syndrome (NPS) is a rare autosomal dominant disorder that is characterized by dysplasia of the nails, hypoplasia and/or dislocation of the patella and the presence of iliac horns. Using the CARE guidelines, we present the first reported case of NPS that was newly diagnosed at the onset of rheumatoid arthritis (RA).
Case presentation A 74-year-old man was admitted to our hospital due to an 8-month history of arthralgia in bilateral wrists, elbows and fingers. He had a past history of glaucoma and left patella dislocation that had been operatively recentered at the age of 15 years. Laboratory data showed elevated levels of serum C-reactive protein and rheumatoid factor and an elevated titer of anti-SS-A antibodies, while estimated glomerular filtration rate (eGFR), titers of other antibodies and the results of a urinary test were normal. An X-ray showed deformity of bilateral radial heads and the right elbow, and magnetic resonance imaging (MRI) of his hands showed synovitis and erosion in the multiple swollen joints of the wrists and fingers. In addition to these typical features of RA, he had bilateral thumb nail dysplasia with mild hypoplasia of bilateral patellae and iliac horns as shown by the X-ray. He was diagnosed as having autosomal dominant disorder NPS co-existing with RA and he was treated with methotrexate in combination with an oral Janus kinase (JAK) inhibitor, leading to induction of remission.
Conclusions We have presented a rare case of NPS that was newly diagnosed at the onset of RA. Clinical and radiographic findings of NPS are highlighted in this case report for diagnosing NPS on the basis of typical manifestations. en-copyright= kn-copyright= en-aut-name=MatsumotoKazuya en-aut-sei=Matsumoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoYoshinori en-aut-sei=Matsumoto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NawachiShoichi en-aut-sei=Nawachi en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsanoYosuke en-aut-sei=Asano en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaYu en-aut-sei=Katayama en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyawakiYoshia en-aut-sei=Miyawaki en-aut-mei=Yoshia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatsuyamaEri en-aut-sei=Katsuyama en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SadaKen-Ei en-aut-sei=Sada en-aut-mei=Ken-Ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Nail-patella syndrome kn-keyword=Nail-patella syndrome en-keyword=Rheumatoid arthritis kn-keyword=Rheumatoid arthritis en-keyword=Joint dislocation kn-keyword=Joint dislocation en-keyword=Iliac horn kn-keyword=Iliac horn en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=9 article-no= start-page=1756 end-page=1764 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthetic strategies for the construction of C3?N1′ bisindoles en-subtitle= kn-subtitle= en-abstract= kn-abstract=C3?N1′ bisindoles are unique structures, and the construction of these structures has drawn much attention. However, their synthesis still presents significant challenges that limit the functional group compatibility. This minireview summarizes the recent progress in the methodology for constructing C3?N1′ bisindoles. There are two approaches for access to C3?N1′ bisindoles: (1) direct approaches including reverse polarity techniques. (2) Stepwise approaches using designed and prefunctionalized substrates enable further functionalization by additional reactions to facilitate access to the target products. I believe that this review will allow its readers to develop novel approaches for the synthesis of C3?N1′ bisindoles. en-copyright= kn-copyright= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=013005 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Periodic superradiance in an Er:YSO crystal en-subtitle= kn-subtitle= en-abstract= kn-abstract=We observed periodic optical pulses from an Er:YSO crystal during irradiating with a continuous-wave excitation laser. We refer to this phenomenon as "periodic superradiance." This periodicity can be understood qualitatively by a simple model, in which a cyclic process of a continuous supply of population inversion and a sudden burst of superradiance is repeated. The excitation power dependences of peak interval and the pulse area can be interpreted with our simple model. In addition, the linewidth of superradiance is much narrower than an inhomogeneous broadening in a crystal. This result suggests that only Er3+ ions in a specific environment are involved in superradiance. en-copyright= kn-copyright= en-aut-name=HaraHideaki en-aut-sei=Hara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanJunseok en-aut-sei=Han en-aut-mei=Junseok kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiYasutaka en-aut-sei=Imai en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasaoNoboru en-aut-sei=Sasao en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshimiAkihiro en-aut-sei=Yoshimi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimuraKoji en-aut-sei=Yoshimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraMotohiko en-aut-sei=Yoshimura en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=1 article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of Notch1 protein expression in methotrexate-associated lymphoproliferative disorders en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methotrexate (MTX)-associated lymphoproliferative disorder (MTX-LPD) is a lymphoproliferative disorder in patients treated with MTX. The mechanism of pathogenesis is still elusive, but it is thought to be a complex interplay of factors, such as underlying autoimmune disease activity, MTX use, Epstein-Barr virus infection, and aging. The NOTCH genes encode receptors for a signaling pathway that regulates various fundamental cellular processes, such as proliferation and differentiation during embryonic development. Mutations of NOTCH1 have been reported in B-cell tumors, including chronic lymphocytic leukemia/ lymphoma, mantle cell lymphoma, and diffuse large B-cell lymphoma (DLBCL). Recently, it has also been reported that NOTCH1 mutations are found in post-transplant lymphoproliferative disorders, and in CD20-positive cells in angioimmunoblastic T-cell lymphoma, which might be associated with lymphomagenesis in immunodeficiency. In this study, to investigate the association of NOTCH1 in the pathogenesis of MTX-LPD, we evaluated protein expression of Notch1 in nuclei immunohistochemically in MTX-LPD cases [histologically DLBCL-type (n = 24) and classical Hodgkin lymphoma (CHL)-type (n = 24)] and de novo lymphoma cases [DLBCL (n = 19) and CHL (n = 15)]. The results showed that among MTX-LPD cases, the expression of Notch1 protein was significantly higher in the DLBCL type than in the CHL type (P < 0.001). In addition, among DLBCL morphology cases, expression of Notch1 tended to be higher in MTX-LPD than in the de novo group; however this difference was not significant (P = 0.0605). The results showed that NOTCH1 may be involved in the proliferation and tumorigenesis of B cells under the use of MTX. Further research, including genetic studies, is necessary. en-copyright= kn-copyright= en-aut-name=OkataniTakeshi en-aut-sei=Okatani en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EgusaYuria en-aut-sei=Egusa en-aut-mei=Yuria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaSayako en-aut-sei=Yoshida en-aut-mei=Sayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=methotrexate-associated lymphoproliferative disorders kn-keyword=methotrexate-associated lymphoproliferative disorders en-keyword=other iatrogenic immunodeficiency-associated lymphoproliferative disorders kn-keyword=other iatrogenic immunodeficiency-associated lymphoproliferative disorders en-keyword=lymphoproliferative disorders arising in immune deficiency/dysregulation kn-keyword=lymphoproliferative disorders arising in immune deficiency/dysregulation en-keyword=NOTCH1 kn-keyword=NOTCH1 END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rhizoviticin is an alphaproteobacterial tailocin that mediates biocontrol of grapevine crown gall disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tailocins are headless phage tail structures that mediate interbacterial antagonism. Although the prototypical tailocins, R- and F-pyocins, in Pseudomonas aeruginosa, and other predominantly R-type tailocins have been studied, their presence in Alphaproteobacteria remains unexplored. Here, we report the first alphaproteobacterial F-type tailocin, named rhizoviticin, as a determinant of the biocontrol activity of Allorhizobium vitis VAR03-1 against crown gall. Rhizoviticin is encoded by a chimeric prophage genome, one providing transcriptional regulators and the other contributing to tail formation and cell lysis, but lacking head formation genes. The rhizoviticin genome retains a nearly intact early phage region containing an integrase remnant and replication-related genes critical for downstream gene transcription, suggesting an ongoing transition of this locus from a prophage to a tailocin-coding region. Rhizoviticin is responsible for the most antagonistic activity in VAR03-1 culture supernatant against pathogenic A. vitis strain, and rhizoviticin deficiency resulted in a significant reduction in the antitumorigenic activity in planta. We identified the rhizoviticin-coding locus in eight additional A. vitis strains from diverse geographical locations, highlighting a unique survival strategy of certain Rhizobiales bacteria in the rhizosphere. These findings advance our understanding of the evolutionary dynamics of tailocins and provide a scientific foundation for employing rhizoviticin-producing strains in plant disease control.

In the ADOPT method, yeast strains overexpressing most of the genes in the budding yeast Saccharomyces cerevisiae genome are mixed and competitively cultured, and the genes overexpressed in the enriched strains are systematically identified. Furthermore, the identified genes can be used to identify bottleneck factors that are necessary but lacking for growth of S. cerevisiae under given conditions. In our previous studies, we have identified bottlenecks in artificially created stress environments in the laboratory, but in this study, we used grape juice for winemaking as an example to see if industrial bottlenecks can be identified. ADOPT experiments with sulfite-added grape juice used in conventional winemaking resulted in a strong enrichment of strains overexpressing the sulfite pump SSU1 and its transcription factor FZF1. Since enhancement of SSU1 function is known to occur in wine yeast acclimation, ADOPT was also shown to be useful in the search for industrial bottlenecks. On the other hand, no genes were strongly enriched by ADOPT in grape juice without sulfite addition, suggesting that grape juice is a balanced medium with few bottlenecks for S. cerevisiae growth. en-copyright= kn-copyright= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name=守屋央朗 kn-aut-sei=守屋 kn-aut-mei=央朗 aut-affil-num=1 ORCID= en-aut-name=OnoChiyuki Kohata en-aut-sei=Ono en-aut-mei=Chiyuki Kohata kn-aut-name=小野千由貴 kn-aut-sei=小野 kn-aut-mei=千由貴 aut-affil-num=2 ORCID= affil-num=1 en-affil=Course of Agrochemical Bioscience kn-affil=農芸化学コース affil-num=2 en-affil=Course of Agrochemical Bioscience kn-affil=農芸化学コース en-keyword=yeast kn-keyword=yeast en-keyword=S. cerevisiae kn-keyword=S. cerevisiae en-keyword=overexpression kn-keyword=overexpression en-keyword=wine making kn-keyword=wine making END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=11 article-no= start-page=e202302963 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On Demand Synthesis of C3?N1’ Bisindoles by a Formal Umpolung Strategy: First Total Synthesis of (±)‐Rivularin A en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this work, a straightforward synthesis of C3?N1’ bisindolines is achieved by a formal umpolung strategy.

This network is important since intercellular communication via the network is essential for bone metabolism. However, the factors that influence the formation of this osteocyte network remain unknown. As the early stage of osteocyte network formation occurs on the bone surface, we observed a newly formed trabecular bone surface by orthogonal focused ion beam-scanning electron microscopy. The embedding late osteoblast processes tended to avoid bundled collagen fibrils and elongate into sparse collagen fibrils. Then, we examined whether the inhibition of bundling of collagen fibrils using a potent lysyl oxidase inhibitor, beta-aminopropionitrile (BAPN) changed the cellular network of the chick calvaria. The osteocyte shape of the control group was spindle-shape, while that of the BAPN group was sphere-shaped. In addition, the osteocyte processes of the control group were elongated vertically to the long axis of the cell body, whereas the osteocyte processes of the BAPN group were elongated radially. Therefore, it was suggested that the bundling of collagen fibrils influences normal osteocyte network formation during bone modeling. en-copyright= kn-copyright= en-aut-name=HashimotoMana en-aut-sei=Hashimoto en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahashiHaruka en-aut-sei=Takahashi en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Tabata-OkuboKaori en-aut-sei=Tabata-Okubo en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TokunagaKazuaki en-aut-sei=Tokunaga en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumoriHaruka en-aut-sei=Matsumori en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshiharaYoshihito en-aut-sei=Ishihara en-aut-mei=Yoshihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KakuMasaru en-aut-sei=Kaku en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IimuraTadahiro en-aut-sei=Iimura en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HaraToru en-aut-sei=Hara en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=5 en-affil=Nikon Corporation kn-affil= affil-num=6 en-affil=Nikon Corporation kn-affil= affil-num=7 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Division of Bio?prosthodontics, Faculty of Dentistry and Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=9 en-affil=Department of Pharmacology, Faculty and Graduate School of Dental Medicine, Hokkaido University kn-affil= affil-num=10 en-affil=Research Center for Structural Materials, National Institute for Materials Science kn-affil= affil-num=11 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=4 article-no= start-page=246 end-page=250 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sutimlimab suppresses SARS-CoV-2 mRNA vaccine-induced hemolytic crisis in a patient with cold agglutinin disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cold agglutinin disease (CAD) is a rare form of acquired autoimmune hemolytic anemia driven mainly by antibodies that activate the classical complement pathway. Several patients with CAD experience its development or exacerbation of hemolysis after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or after receiving the SARS-CoV-2 mRNA vaccine. Therefore, these patients cannot receive an additional SARS-CoV-2 mRNA vaccination and have a higher risk of severe SARS-CoV-2 infection. Sutimlimab is a monoclonal antibody that inhibits the classical complement pathway of the C1s protein and shows rapid and sustained inhibition of hemolysis in patients with CAD. However, whether sutimlimab could also inhibit hemolysis caused by SARS-CoV-2 mRNA vaccination is uncertain. Here, we present the case of a 70-year-old man with CAD who repeatedly experienced a hemolytic crisis after receiving SARS-CoV-2 mRNA vaccines. The patient eventually underwent SARS-CoV-2 mRNA vaccination safely, without hemolytic attack, under classical pathway inhibition therapy with sutimlimab. This report suggests that appropriate sutimlimab administration can suppress SARS-CoV-2 mRNA vaccination-induced CAD exacerbation, and that it could be a preventive strategy to minimize hemolytic attacks in susceptible populations. en-copyright= kn-copyright= en-aut-name=KobayashiHiroki en-aut-sei=Kobayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OuchiTomoki en-aut-sei=Ouchi en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsakuraShoji en-aut-sei=Asakura en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanoTomofumi en-aut-sei=Yano en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakedaHiromasa en-aut-sei=Takeda en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TokudaYoshiyuki en-aut-sei=Tokuda en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=8 en-affil=Department of Pathology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cold agglutinin disease kn-keyword=cold agglutinin disease en-keyword=severe acute respiratory syndrome coronavirus 2 kn-keyword=severe acute respiratory syndrome coronavirus 2 en-keyword=sutimlimab kn-keyword=sutimlimab END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=RP88822 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of tryptophan oxidation affecting D1 degradation by FtsH in the photosystem II quality control of chloroplasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthesis is one of the most important reactions for sustaining our environment. Photosystem II (PSII) is the initial site of photosynthetic electron transfer by water oxidation. Light in excess, however, causes the simultaneous production of reactive oxygen species (ROS), leading to photo-oxidative damage in PSII. To maintain photosynthetic activity, the PSII reaction center protein D1, which is the primary target of unavoidable photo-oxidative damage, is efficiently degraded by FtsH protease. In PSII subunits, photo-oxidative modifications of several amino acids such as Trp have been indeed documented, whereas the linkage between such modifications and D1 degradation remains elusive. Here, we show that an oxidative post-translational modification of Trp residue at the N-terminal tail of D1 is correlated with D1 degradation by FtsH during high-light stress. We revealed that Arabidopsis mutant lacking FtsH2 had increased levels of oxidative Trp residues in D1, among which an N-terminal Trp-14 was distinctively localized in the stromal side. Further characterization of Trp-14 using chloroplast transformation in Chlamydomonas indicated that substitution of D1 Trp-14 to Phe, mimicking Trp oxidation enhanced FtsH-mediated D1 degradation under high light, although the substitution did not affect protein stability and PSII activity. Molecular dynamics simulation of PSII implies that both Trp-14 oxidation and Phe substitution cause fluctuation of D1 N-terminal tail. Furthermore, Trp-14 to Phe modification appeared to have an additive effect in the interaction between FtsH and PSII core in vivo. Together, our results suggest that the Trp oxidation at its N-terminus of D1 may be one of the key oxidations in the PSII repair, leading to processive degradation by FtsH. en-copyright= kn-copyright= en-aut-name=KatoYusuke en-aut-sei=Kato en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaHiroshi en-aut-sei=Kuroda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzawaShin-Ichiro en-aut-sei=Ozawa en-aut-mei=Shin-Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoKeisuke en-aut-sei=Saito en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DograVivek en-aut-sei=Dogra en-aut-mei=Vivek kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ScholzMartin en-aut-sei=Scholz en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhangGuoxian en-aut-sei=Zhang en-aut-mei=Guoxian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=de VitryCatherine en-aut-sei=de Vitry en-aut-mei=Catherine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshikitaHiroshi en-aut-sei=Ishikita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KimChanhong en-aut-sei=Kim en-aut-mei=Chanhong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HipplerMichael en-aut-sei=Hippler en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakahashiYuichiro en-aut-sei=Takahashi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Research Center for Advanced Science and Technology, The University of Tokyo kn-affil= affil-num=5 en-affil=Shanghai Center for Plant Stress Biology, Center for Excellence in Molecular Plant Sciences, Chinese Academy of Sciences kn-affil= affil-num=6 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=8 en-affil=Institut de Biologie Physico-Chimique, Unit?

Recent literature also suggests that there is an additional COO subtype associated with the germinal center dark zone (DZ) that warrants wider validation to generalize clinical relevance. Here, we assembled a cohort of Japanese patients with untreated DLBCL and determined the refined COO subtypes, which include the DZ signature (DZsig), using the NanoString DLBCL90 assay. To compare the distribution and clinical characteristics of the molecular subtypes, we used a data set from the cohort of British Columbia Cancer (BCC) (n = 804). Through the 1050 patient samples on which DLBCL90 assay was successfully performed in our cohort, 35%, 45%, and 6% of patients were identified to have germinal center B-cell?like (GCB) DLBCL, activated B-cell?like (ABC) DLBCL, and DZsig-positive (DZsigpos) DLBCL, respectively, with the highest prevalence of ABC-DLBCL, differing significantly from the BCC result (P < .001). GCB-DLBCL, ABC-DLBCL, and DZsigpos-DLBCL were associated with 2-year overall survival rates of 88%, 75%, and 66%, respectively (P < .0001), with patients with DZsigpos-DLBCL having the poorest prognosis. In contrast, GCB-DLBCL without DZsig showed excellent outcomes after rituximab-containing immunochemotherapy. DZsigpos-DLBCL was associated with the significant enrichment of tumors with CD10 expression, concurrent MYC/BCL2 expression, and depletion of microenvironmental components (all, P < .05). These results provide evidence of the distinct distribution of clinically relevant molecular subtypes in Japanese DLBCL and that refined COO, as measured by the DLBCL90 assay, is a robust prognostic biomarker that is consistent across geographical areas. en-copyright= kn-copyright= en-aut-name=UrataTomohiro en-aut-sei=Urata en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

Veno-Muscular Characteristics and Kidney Disease Progression: A Native Kidney-Biopsy Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rationale & Objective: Assessment of kidney biopsies provides crucial information for diagnosis and disease activity, as well as prognostic value. Kidney-biopsy specimens occasionally contain veno-muscular complex (VMC), which consists of muscle tissues around the kidney venous system in the corticomedullary region. However, the role of VMC and the clinical significance of VMC variants are poorly understood. In the present study, we investigated kidney prognostic values of VMC variants.
Study Design: Retrospective cohort study.
Setting & Participants: Among 808 patients who underwent a kidney biopsy from 2011 to 2019, 246 patients whose kidney biopsy specimens contained VMC were enrolled.
Predictors: VMC variants; inflammatory-VMC (an infiltration of ?80 inflammatory cells/mm2-VMC area) and VMC hypertrophy (hyper-VMC, a VMC average width ?850 μm), and the interstitial fibrosis/tubular atrophy (IFTA) score.
Outcomes: A decline in estimated glomerular filtration rate (eGFR) ?40% from the baseline or commencement of kidney replacement therapy.
Analytical Approach: Cox proportional hazards model.
Results: Among 246 patients with data on VMC, mean baseline eGFR was 56.0±25.6 ml/min per 1.73 m2; 80 had high inflammatory-VMC, and 62 had VMC hypertrophy. There were 51 kidney events over median follow-up of 2.5 years. We analyzed 2 VMC variants. Multivariable logistic regression analysis revealed that eGFR negatively correlated with the presence of both inflammatory-VMC and hyper-VMC. A Cox proportional hazards analysis revealed that inflammatory-VMC (but not hyper-VMC) was independently associated with the primary outcome after adjustments for known risk factors of progression, including proteinuria, eGFR, and the interstitial fibrosis/tubular atrophy (IFTA) score (hazard ratio, 1.97; 95% confidence interval, 1.00-3.91).
Limitations: Single-center study and small sample size.
Conclusions: Assessment of inflammatory-VMC provides additional kidney prognostic information to known indicators of kidney disease progression in patients who undergo kidney biopsy. en-copyright= kn-copyright= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiKensaku en-aut-sei=Takahashi en-aut-mei=Kensaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaTakafumi en-aut-sei=Morita en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SangYizhen en-aut-sei=Sang en-aut-mei=Yizhen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Matsuoka-UchiyamaNatsumi en-aut-sei=Matsuoka-Uchiyama en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=153 cd-vols= no-issue= article-no= start-page=107623 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prediction of slip activity of crystal grains around semi-circular and semi-elliptical notches in thin-sheet specimens of pure titanium using formulated macroscopic stress distribution and crystal orientation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thin metal sheets and wires are important materials for various devices used in electrical, mechanical, and medical fields. With the downsizing of these devices, demand for thinner sheets and wires has increased. Amongst the many metals available, pure titanium has been attracting much attention for use in medical and dental devices because of its good biocompatibility in addition to its light weight and high corrosion resistance. However, thin metal sheets and wires are usually polycrystalline materials and, with the downsizing of materials, there is a loss of homogeneity during deformations. Inhomogeneous deformation becomes significant in thin sheets and wires, owing to the different crystal orientations and geometries of crystal grains. Furthermore, the shapes of such devices are not uniform, unlike, say, a simple rod. Therefore, macroscopic stress and strain concentrations should be taken into consideration when designing these devices as they affect the localization of deformation and the resultant fracture. In this study, semi-circular and semi-elliptical notched specimens made of thin-sheet polycrystalline pure titanium are subjected to tensile testing. Inhomogeneous deformation caused by crystallographic slip is observed near the notch root. Analysis of the crystal orientation and observation of the slip line show that the slip initiation in crystal grains is affected by the macroscopic stress distribution and can be predicted from the slip activity calculated from both the critical resolved shear stress on the slip systems and the resolved shear stress acting on prospective slip planes obtained from the macroscopic multiaxial stress distribution. en-copyright= kn-copyright= en-aut-name=TadaNaoya en-aut-sei=Tada en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UemoriTakeshi en-aut-sei=Uemori en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoJunji en-aut-sei=Sakamoto en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Mechanical engineering kn-keyword=Mechanical engineering en-keyword=Microdevices made of thin metal sheet kn-keyword=Microdevices made of thin metal sheet en-keyword=Pure titanium kn-keyword=Pure titanium en-keyword=Deformation kn-keyword=Deformation en-keyword=Microscopic characterization and microanalysis kn-keyword=Microscopic characterization and microanalysis en-keyword=Plastic deformation kn-keyword=Plastic deformation en-keyword=Microscopic inhomogeneity and stress kn-keyword=Microscopic inhomogeneity and stress en-keyword=concentration kn-keyword=concentration en-keyword=Slip activity control kn-keyword=Slip activity control END start-ver=1.4 cd-journal=joma no-vol=1278 cd-vols= no-issue= article-no= start-page=341723 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Determination of mass-dependent chromium isotopic compositions in geological samples by double spike-total evaporation-thermal ionization mass spectrometry (DS-TE-TIMS) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Chromium isotopes have been used to trace geochemical and cosmochemical processes in the past. However, the presence of multivalent Cr species has made it difficult to isolate Cr from geological samples, particularly for samples with a low Cr mass fraction.
Results: Here, a simple three-step ion exchange chromatography procedure is presented to separate Cr from various sample matrices, ranging from ultramafic to felsic rocks. Throughout each of the column chromatography step, 1 mL of cation exchange resin AG50W-X8 (200?400 mesh) was used as the stationary phase and oxalic acid as a chelating agent, was used in addition to the inorganic acids. This method yielded high recoveries of Cr [93 ± 8% (2SD, N = 7)] regardless of the lithology. The total procedural blank of Cr was <0.5 ng. We also developed a double spike-total evaporation-thermal ionization mass spectrometry (DS-TE-TIMS) technique that significantly reduced sample consumption to ?20 ng of Cr per each measurement of mass-dependent 53Cr/52Cr.
Significance: This study achieved a 2SD external precision of 0.02‰ for the analysis of NIST NBS3112a and of 0.01?0.07‰ for the geological samples. This study enabled high-precision Cr isotope analysis in geological samples with various matrix and Cr compositions using relatively small sample volumes. en-copyright= kn-copyright= en-aut-name=RatnayakeDilan M. en-aut-sei=Ratnayake en-aut-mei=Dilan M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaRyoji en-aut-sei=Tanaka en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraEizo en-aut-sei=Nakamura en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Cr isotopes kn-keyword=Cr isotopes en-keyword=DS-TE-TIMS kn-keyword=DS-TE-TIMS en-keyword=Cation exchange resin kn-keyword=Cation exchange resin en-keyword=Low blank kn-keyword=Low blank en-keyword=High precision kn-keyword=High precision END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=10 article-no= start-page=100573 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immunologic Significance of CD80/CD86 or Major Histocompatibility Complex-II Expression in Thymic Epithelial Tumors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Unresectable or recurrent thymic epithelial tumors (TETs) have a poor prognosis, and treatment options are limited. This study aimed to investigate the immunologic significance of CD80/CD86 or major histocompatibility complex class II (MHC-II) expression in TETs, as potential predictive biomarkers for immune checkpoint inhibitors (ICIs).
Methods: We analyzed CD80, CD86, MHC class I (MHC-I), and MHC-II expression in TETs using immunohistochemistry and investigated their association with T-cell infiltration or ICI efficacy. In addition, we generated CD80- or MHC-II?expressing mouse tumors, evaluated the effects of ICIs, and analyzed tumor-infiltrating lymphocytes. We also performed tumor-rechallenge experiments in vivo.
Results: We found that approximately 50% and 30% of TETs had high expression of CD80/CD86 and MHC-II in tumor cells, respectively, and that this expression was related to T-cell infiltration in clinical samples. In mouse models, both CD80 and MHC-II increase the effects of ICIs. In addition, senescent T cells and long-lived memory precursor effector T cells were significantly decreased and increased, respectively, in tumor-infiltrating lymphocytes from CD80-expressing tumors, and rechallenged tumors were completely rejected after the initial eradication of CD80-expressing tumors by programmed cell death protein 1 blockade. Indeed, patients with CD80-high thymic carcinoma had longer progression-free survival with anti?programmed cell death protein 1 monoclonal antibody.
Conclusions: Half of the TETs had high expression of CD80/CD86 or MHC-II with high T-cell infiltration. These molecules could potentially increase the effects of ICIs, particularly inducing a durable response. CD80/CD86 and MHC-II can be predictive biomarkers of ICIs in TETs, promoting the development of drugs for such TETs. en-copyright= kn-copyright= en-aut-name=IkedaHideki en-aut-sei=Ikeda en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuDaiki en-aut-sei=Shimizu en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsuyaYuki en-aut-sei=Katsuya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HorinouchiHidehito en-aut-sei=Horinouchi en-aut-mei=Hidehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HosomiYukio en-aut-sei=Hosomi en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanjiEtsuko en-aut-sei=Tanji en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwataTakekazu en-aut-sei=Iwata en-aut-mei=Takekazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItamiMakiko en-aut-sei=Itami en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawazuMasahito en-aut-sei=Kawazu en-aut-mei=Masahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OheYuichiro en-aut-sei=Ohe en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SuzukiTakuji en-aut-sei=Suzuki en-aut-mei=Takuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Chiba Cancer Center, Research Institute kn-affil= affil-num=2 en-affil=Chiba Cancer Center, Research Institute kn-affil= affil-num=3 en-affil=Division of Thoracic Surgery, Chiba Cancer Center kn-affil= affil-num=4 en-affil=Department of Experimental Therapeutics, National Cancer Center Hospital kn-affil= affil-num=5 en-affil=Department of Thoracic Oncology, National Cancer Center Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Oncology and Respiratory Medicine, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital kn-affil= affil-num=7 en-affil=Chiba Cancer Center, Research Institute kn-affil= affil-num=8 en-affil=Division of Thoracic Surgery, Chiba Cancer Center kn-affil= affil-num=9 en-affil=Department of Surgical Pathology, Chiba Cancer Center kn-affil= affil-num=10 en-affil=Chiba Cancer Center, Research Institute kn-affil= affil-num=11 en-affil=Department of Thoracic Oncology, National Cancer Center Hospital kn-affil= affil-num=12 en-affil=Department of Respirology, Graduate School of Medicine, Chiba University kn-affil= affil-num=13 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Thymic epithelial tumor kn-keyword=Thymic epithelial tumor en-keyword=Cancer immunotherapy kn-keyword=Cancer immunotherapy en-keyword=CD80/CD86 kn-keyword=CD80/CD86 en-keyword=MHC kn-keyword=MHC en-keyword=Memory precursor effector T cell kn-keyword=Memory precursor effector T cell END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue= article-no= start-page=102337 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Continued mycovirus discovery expanding our understanding of virus lifestyles, symptom expression, and host defense en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-throughput sequencing technologies have greatly expanded the RNA virome in general and have led to an exponential increase in new fungal viruses, also known as mycoviruses. Mycoviruses are omnipresent in fungi and usually induce symptomless infections. Some mycoviruses infecting fungi pathogenic to plants, insects, and mammals are known to modify host virulence positively and negatively and attract particular interests. In addition, fungal viruses continue to provide intriguing research materials and themes that lead to discoveries of peculiar viruses as infectious entities and insights into virus evolution and diversity. In this review, we outline the diversity and neolifestyle of recently discovered fungal RNA viruses, and phenotypic alterations induced by them. Furthermore, we discuss recent advances in research regarding the fungal antiviral defense and viral counterdefense, which are closely associated with host phenotype alterations. We hope that this article will enhance understanding of the interesting and growing fungal virology field. en-copyright= kn-copyright= en-aut-name=SatoYukiyo en-aut-sei=Sato en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Plant Sciences, University of Cologne kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=6 article-no= start-page=1208 end-page=1219 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nuclear Transformation of the Marine Pennate Diatom Nitzschia sp. Strain NIES-4635 by Multi-Pulse Electroporation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nitzschia is one of the largest genera of diatoms found in a range of aquatic environments, from freshwater to seawater. This genus contains evolutionarily and ecologically unique species, such as those that have lost photosynthetic capacity or those that live symbiotically in dinoflagellates. Several Nitzschia species have been used as indicators of water pollution. Recently, Nitzschia species have attracted considerable attention in the field of biotechnology. In this study, a transformation method for the marine pennate diatom Nitzschia sp. strain NIES-4635, isolated from the coastal Seto Inland Sea, was established. Plasmids containing the promoter/terminator of the fucoxanthin chlorophyll a/c binding protein gene (fcp, or Lhcf) derived from Nitzschia palea were constructed and introduced into cells by multi-pulse electroporation, resulting in 500 μg/mL nourseothricin-resistant transformants with transformation frequencies of up to 365 colonies per 108 cells. In addition, when transformation was performed using a new plasmid containing a promoter derived from a diatom-infecting virus upstream of the green fluorescent protein gene (gfp), 44% of the nourseothricin-resistant clones exhibited GFP fluorescence. The integration of the genes introduced into the genomes of the transformants was confirmed by Southern blotting. The Nitzschia transformation method established in this study will enable the transformation this species, thus allowing the functional analysis of genes from the genus Nitzschia, which are important species for environmental and biotechnological development. en-copyright= kn-copyright= en-aut-name=OkadaKoki en-aut-sei=Okada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimotoYu en-aut-sei=Morimoto en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiraishiYukine en-aut-sei=Shiraishi en-aut-mei=Yukine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MayamaShigeki en-aut-sei=Mayama en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadonoTakashi en-aut-sei=Kadono en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AdachiMasao en-aut-sei=Adachi en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=The Advanced Support Center for Science Teachers, Tokyo Gakugei University kn-affil= affil-num=6 en-affil=Faculty of Agriculture and Marine Science, Kochi University kn-affil= affil-num=7 en-affil=Faculty of Agriculture and Marine Science, Kochi University kn-affil= affil-num=8 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Diatom kn-keyword=Diatom en-keyword=Genetic transformation kn-keyword=Genetic transformation en-keyword=Nitzschia kn-keyword=Nitzschia en-keyword=Multi-pulse electroporation kn-keyword=Multi-pulse electroporation END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=23 article-no= start-page=38529 end-page=38539 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optical multi-context scrubbing operation on a redundant system en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents a proposal of the world-first optical multi-context scrubbing operation on a redundant system that can maintain the state of a sequential circuit and the operation continuously without any interruption on a radiation-hardened optically reconfigurable gate array even after a permanent failure suddenly happens on the sequential circuit or a flip-flop by radiation. Up to now, a high-speed optical scrubbing operation has been demonstrated on a radiation-hardened optically reconfigurable gate array. In addition, a multi-context scrubbing operation based on the high-speed optical scrubbing operation has already been demonstrated. Although the multi-context scrubbing operation presents the benefit that it can treat both soft errors and permanent failures caused by radiation simultaneously, the conventional contributions have never presented how to maintain the state of a sequential circuit after a permanent failure occurs on flip-flops. Therefore, in the conventional multi-context scrubbing operation, all the operations must be restarted from the initial condition each time a permanent failure occurs on a programmable gate array. As a result, conventional multi-context scrubbing operations could not be applied for real-time systems. The proposed optical multi-context scrubbing method that can solve the issue has been experimentally evaluated on a radiation-hardened optically reconfigurable gate array. en-copyright= kn-copyright= en-aut-name=AndoKakeru en-aut-sei=Ando en-aut-mei=Kakeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeMinoru en-aut-sei=Watanabe en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeNobuya en-aut-sei=Watanabe en-aut-mei=Nobuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=35 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current status and challenges of breast cancer prevention?DNA methylation would lead to groundbreaking progress in breast cancer prevention? en-subtitle= kn-subtitle= en-abstract= kn-abstract=The number of breast cancer patients is increasing worldwide. Furthermore, breast cancer often develops in young people, even those only in their 30s, who play a central role in their families and society. Results from many cohort studies suggest that dietary factors, alcohol consumption, lack of physical activity, obesity, nulliparity, breastfeeding, oral contraceptive use, fertility treatment and hormone replacement therapy are risk factors for breast cancer. However, the effects of lifestyle habits on the human body are complexly intertwined with various factors, and the effects vary from person to person depending on their constitution, etc., so there is no basis for this. Therefore, primary prevention of breast cancer is still not being implemented appropriately and efficiently. Furthermore, advances in genomic technology make it possible to assess the risk of developing breast cancer in some individuals. As a result, the establishment of breast cancer prevention methods has become a health priority for high-risk individuals. Drugs such as tamoxifen and raloxifene are known to prevent the development of breast cancer, based on the results of multiple randomized controlled trials, but there are concerns regarding the side effects of these powerful agents. In addition, several clinical studies have shown that prophylactic mastectomy for women who have BRCA mutations or who are identified as being at high risk reduces the incidence of breast cancer development. However, many issues, such as changes in long-term quality of life after preventive surgery, the optimal timing of surgery and the identification of women who are at high risk but will not develop breast cancer, remain uncertain. In other words, although many researchers have focused on chemoprevention and surgical prevention and clear preventive effects of these strategies have been confirmed, it cannot be said that they are widely accepted. Therefore, the current evidence for chemoprevention and surgical prevention, as well as highlights of several interesting lines of research currently underway, are summarized in this article. en-copyright= kn-copyright= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KhanSeema A. en-aut-sei=Khan en-aut-mei=Seema A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrine Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Feinberg School of Medicine of Northwestern University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrine Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Prevention kn-keyword=Prevention en-keyword=Risk reduction mastectomy kn-keyword=Risk reduction mastectomy en-keyword=Chemoprevention kn-keyword=Chemoprevention en-keyword=Methylation kn-keyword=Methylation END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=11 article-no= start-page=424 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Hexagonal Pyramid-Shaped Flexible Actuator with Anisotropic Stiffness for Upper-Limb Rehabilitation Device en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rehabilitation devices for passive exercise have been actively researched and developed in accordance with Japan's aging society. A previous study proposed and tested an extension-type flexible pneumatic actuator (EFPA) with reinforced stiffness that could achieve passive exercise in patients. In addition, a rehabilitation device for shoulder joints with an embedded controller and small valves was proposed and tested. Joints such as the shoulder and scapula were subjected to passive exercise utilizing the tested device. However, it is difficult for patients with contractions to perform the same exercise because the reinforced EFPA can buckle. Here, to realize an EFPA with a higher stiffness, a flexible actuator in the shape of a hexagonal pyramid is proposed and tested. The hexagonal pyramid shape of a flexible actuator has a high stiffness in the direction of motion and flexibility in other directions; hereafter, this characteristic is called anisotropic stiffness. The characteristics of the hexagonal pyramid shape of the EFPA are described and compared with those of a previously reinforced EFPA. An analytical model was proposed to predict and design the shape of the hexagonal pyramid EFPA. The validity of the model is also described. en-copyright= kn-copyright= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HimuroHiroki en-aut-sei=Himuro en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GofukuAkio en-aut-sei=Gofuku en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=hexagonal pyramid shape of flexible actuator kn-keyword=hexagonal pyramid shape of flexible actuator en-keyword=anisotropic stiffness kn-keyword=anisotropic stiffness en-keyword=extension-type flexible pneumatic actuator kn-keyword=extension-type flexible pneumatic actuator en-keyword=analytical model of shape kn-keyword=analytical model of shape END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=12 article-no= start-page=1481 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Random Mutational Analysis Targeting Residue K155 within the Transmembrane β-Hairpin of the Mosquitocidal Mpp46Ab Toxin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mpp46Ab is a mosquito-larvicidal pore-forming toxin derived from Bacillus thuringiensis TK-E6. Pore formation is believed to be a central mode of Mpp46Ab action, and the cation selectivity of the channel pores, in particular, is closely related to its mosquito-larvicidal activity. In the present study, we constructed a mutant library in which residue K155 within the transmembrane β-hairpin was randomly replaced with other amino acid residues. Upon mutagenesis and following primary screening using Culex pipiens mosquito larvae, we obtained 15 mutants in addition to the wild-type toxin. Bioassays using purified proteins revealed that two mutants, K155E and K155I, exhibited toxicity significantly higher than that of the wild-type toxin. Although increased cation selectivity was previously reported for K155E channel pores, we demonstrated in the present study that the cation selectivity of K155I channel pores was also significantly increased. Considering the characteristics of the amino acids, the charge of residue 155 may not directly affect the cation selectivity of Mpp46Ab channel pores. Replacement of K155 with glutamic acid or isoleucine may induce a similar conformational change in the region associated with the ion selectivity of the Mpp46Ab channel pores. Mutagenesis targeting the transmembrane β-hairpin may be an effective strategy for enhancing the ion permeability of the channel pores and the resulting mosquito-larvicidal activity of Mpp46Ab. en-copyright= kn-copyright= en-aut-name=MiyazakiMidoka en-aut-sei=Miyazaki en-aut-mei=Midoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsakuraMami en-aut-sei=Asakura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IdeToru en-aut-sei=Ide en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayakawaTohru en-aut-sei=Hayakawa en-aut-mei=Tohru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=mosquito-larvicidal toxin kn-keyword=mosquito-larvicidal toxin en-keyword=Bacillus thuringiensis TK-E6 kn-keyword=Bacillus thuringiensis TK-E6 en-keyword=Culex pipiens mosquito larvae kn-keyword=Culex pipiens mosquito larvae en-keyword=site-directed mutagenesis kn-keyword=site-directed mutagenesis en-keyword=electrophysiologic analysis kn-keyword=electrophysiologic analysis END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=21 end-page=40 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Parameter study of strong ground motion simulation for the Median Tectonic Line in the case of the Iyo-Bungo Earthquake of September 1st, 1596 kn-title=文禄五年閏七月九日の伊予・豊後地震に関する特性化震源モデルを用いた中央構造線活断層帯の断層パラメータの検証 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this study is to verify the fault length and earthquake magnitude of the Iyo-Bungo earthquake in 1596 estimated by Ishibashi (2019) using historical documents written in the same period. According to Ishibashi (2019), the length of the source fault was estimated to have been less than 100 km and the earthquake magnitude was roughly estimated to have been around 7.5. In order to attempt to reproduce the interpretation, we conducted two different strong ground motion simulations: the attenuation equation method and the characterized source model method, both used in the Headquarters for Earthquake Research Promotion. We simulated earthquake ground motions based on several source fault models including estimation by Ishibashi (2019). For the length of the fault, a 100 km length corresponding to the Iyonada segment of the Median Tectonic Line active fault system was the first model and 130 km and 160 km models extending onshore to the northeast were taken into account as epistemic uncertainties. Regarding the dip angle of the fault, both 40 and 90 degree models were considered also as epistemic uncertainties. Our calculation with other uncertainties shows that the models with a fault length of 100 km with a dip angle of 90 or 40 degrees are consistent with the seismic intensity and seismogenic fault length of offshore fault estimated by Ishibashi (2019) based on reliable first-grade documents. If low-certainty intensity estimates by Ishibashi (2019) are used to evaluate fault length in our calculation, the possibility of 130 or 160 km length models with additional onshore faults will remain. Our results show that the strong ground motion simulation could reinforce the expert’s interpretation of historical documents and propose quantitative source fault models for historical earthquakes. en-copyright= kn-copyright= en-aut-name=OKUMAYurie en-aut-sei=OKUMA en-aut-mei=Yurie kn-aut-name=大熊祐里英 kn-aut-sei=大熊 kn-aut-mei=祐里英 aut-affil-num=1 ORCID= en-aut-name=KUMAMOTOTakashi en-aut-sei=KUMAMOTO en-aut-mei=Takashi kn-aut-name=隈元崇 kn-aut-sei=隈元 kn-aut-mei=崇 aut-affil-num=2 ORCID= affil-num=1 en-affil=School of Science, Okayama University kn-affil= affil-num=2 en-affil=School of Science, Okayama University kn-affil= en-keyword=Median Tectonic Line kn-keyword=Median Tectonic Line en-keyword=1596 Iyo-Bungo earthquake kn-keyword=1596 Iyo-Bungo earthquake en-keyword=strong ground motion simulation kn-keyword=strong ground motion simulation en-keyword=epistemic uncertainties kn-keyword=epistemic uncertainties END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safety and Clinical Effects of a Muse Cell-Based Product in Patients With Amyotrophic Lateral Sclerosis: Results of a Phase 2 Clinical Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Amyotrophic lateral sclerosis (ALS) is characterized by progressive loss of motor neurons. Multilineage-differentiating stress-enduring (Muse) cells are unique endogenous stem cells that show therapeutic effects on motor function in ALS mouse models. We conducted a single-center open phase II clinical trial to evaluate the safety and clinical effects of repeated intravenous injections of an allogenic Muse cell-based product, CL2020, in patients with ALS. Five patients with ALS received CL2020 intravenously once a month for a total of six doses. The primary endpoints were safety and tolerability, and the secondary endpoint was the rate of change in the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score. In addition, serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), sphingosine-1-phosphate (S1P), cerebrospinal fluid chitotriosidase-1 (CHIT-1), and neurofilament light chain (NfL) levels were evaluated. The CL2020 treatment was highly tolerated without serious side effects. The ALSFRS-R score change trended upward at 12 months post-CL2020 treatment compared with that at 3 months pre-administration, but the difference was not statistically significant. Among five patients diagnosed with ALS, three exhibited a decrease in the rate of ALSFRS-R score change, one demonstrated an increase, and another showed no change. In addition, the patients’ serum IL-6 and TNF-α levels and cerebrospinal fluid CHIT-1 and NfL levels increased for up to 6 months post-treatment; however, their serum S1P levels continuously decreased over 12 months. These findings indicate a favorable safety profile of CL2020 therapy. In the near future, a double-blind study of a larger number of ALS patients should be conducted to confirm the efficacy of ALS treatment with CL2020. en-copyright= kn-copyright= en-aut-name=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasakiRyo en-aut-sei=Sasaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TadokoroKoh en-aut-sei=Tadokoro en-aut-mei=Koh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OmoteYoshio en-aut-sei=Omote en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawaharaYuko en-aut-sei=Kawahara en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoNamiko en-aut-sei=Matsumoto en-aut-mei=Namiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TairaYuki en-aut-sei=Taira en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuokaChika en-aut-sei=Matsuoka en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=amyotrophic lateral sclerosis kn-keyword=amyotrophic lateral sclerosis en-keyword=clinical trial kn-keyword=clinical trial en-keyword=CL2020 kn-keyword=CL2020 en-keyword=multilineage-differentiating stress-enduring (Muse) cells kn-keyword=multilineage-differentiating stress-enduring (Muse) cells en-keyword=intravenous administration kn-keyword=intravenous administration END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=567 end-page=575 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Review of a Series of Surveys on Adverse Reactions to the COVID-19 mRNA-1273 Vaccine at Okayama University en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents the results of a series of surveys conducted from July 2021 to March 2023 to investigate the post-vaccination adverse reactions to the mRNA-1273 (Moderna) vaccine among faculty, staff, and students at Okayama University. These studies complement the official surveys conducted by the Ministry of Health, Labour and Welfare (MHLW) and provide a more representative picture of adverse reactions in the general population including large numbers of healthy young people. Pain, swelling, redness at the injection site, fever, headache, and malaise were the main adverse reactions reported. The proportion of adverse reactions was generally higher after the second vaccination and decreased with each additional vaccination. No statistically significant differences in the adverse reactions were found for males and females and those with/without a history of allergy, but a lower proportion of fever was observed in older participants and those with underlying medical conditions. We also evaluated the association between adverse reactions and antibody titers after the third vaccination and found no significant differences in antibody levels one month after vaccination.

We demonstrate that μ* of the two amphiphilic solutes can be obtained accurately using a perturbation combining method, which relies on the exact expressions for Image ID:d3cp03799a-t5.gif and Image ID:d3cp03799a-t6.gif and requires no simulations of intermediate systems between the solute with strong, repulsive interactions and the solute with the van der Waals and electrostatic interactions. The decomposition of μ* gives us several physical insights including that μ* is an increasing function of T due to Image ID:d3cp03799a-t7.gif, that the contributions of hydrophilic groups to the temperature dependence of μ* are additive, and that the contribution of the van der Waals attraction to the solvation volume is greater than that of the electrostatic interactions. en-copyright= kn-copyright= en-aut-name=TairaAoi en-aut-sei=Taira en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoRyuichi en-aut-sei=Okamoto en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Information Science, University of Hyogo kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue= article-no= start-page=104585 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Do commodity factors work as inflation hedges and safe havens? en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates whether commodity futures factor portfolios work as hedges and safe havens against inflation shocks. We observe that momentum, basis momentum, and a combination of factor portfolios act as strong hedges against core inflation shocks, suggesting that holding the factor portfolios generates not only higher Sharpe ratios but also strong hedge effects against inflation. Moreover, the momentum, basis momentum, and value portfolios have weak safe haven properties against inflation shocks. In addition, our empirical results suggest that hedge effects for commodity future portfolios are stronger during the pre-financialization period. en-copyright= kn-copyright= en-aut-name=NakagawaKei en-aut-sei=Nakagawa en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakemotoRyuta en-aut-sei=Sakemoto en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Nomura Asset Management Co.

Chest computed tomography showed massive bleeding from the right upper lobe; however, the cause of bleeding was unclear. After bronchial artery embolization (BAE), bronchial occlusion was performed using an Endobronchial Watanabe Spigot (EWS) that was easily placed because BAE had reduced the bleeding volume. Treatment with BAE alone was inadequate; however, additional therapy with EWS after BAE successfully controlled the massive hemoptysis, especially in this patient who underwent lobectomy to prevent respiratory dysfunction. en-copyright= kn-copyright= en-aut-name=TaokaMasataka en-aut-sei=Taoka en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigoHisao en-aut-sei=Higo en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoYuka en-aut-sei=Kato en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiMasanori en-aut-sei=Fujii en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KuboToshio en-aut-sei=Kubo en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TabataMasahiro en-aut-sei=Tabata en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=Hemoptysis kn-keyword=Hemoptysis en-keyword=Bronchial artery embolization kn-keyword=Bronchial artery embolization en-keyword=Endoscopic bronchial occlusion kn-keyword=Endoscopic bronchial occlusion en-keyword=Endobronchial Watanabe Spigot kn-keyword=Endobronchial Watanabe Spigot END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=5 article-no= start-page=536 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the accuracy of heart dose prediction by machine learning for selecting patients not requiring deep inspiration breath?hold radiotherapy after breast cancer surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Increased heart dose during postoperative radiotherapy (RT) for left?sided breast cancer (BC) can cause cardiac injury, which can decrease patient survival. The deep inspiration breath?hold technique (DIBH) is becoming increasingly common for reducing the mean heart dose (MHD) in patients with left?sided BC. However, treatment planning and DIBH for RT are laborious, time?consuming and costly for patients and RT staff. In addition, the proportion of patients with left BC with low MHD is considerably higher among Asian women, mainly due to their smaller breast volume compared with that in Western countries. The present study aimed to determine the optimal machine learning (ML) model for predicting the MHD after RT to pre?select patients with low MHD who will not require DIBH prior to RT planning. In total, 562 patients with BC who received postoperative RT were randomly divided into the trainval (n=449) and external (n=113) test datasets for ML using Python (version 3.8). Imbalanced data were corrected using synthetic minority oversampling with Gaussian noise. Specifically, right?left, tumor site, chest wall thickness, irradiation method, body mass index and separation were the six explanatory variables used for ML, with four supervised ML algorithms used. Using the optimal value of hyperparameter tuning with root mean squared error (RMSE) as an indicator for the internal test data, the model yielding the best F2 score evaluation was selected for final validation using the external test data. The predictive ability of MHD for true MHD after RT was the highest among all algorithms for the deep neural network, with a RMSE of 77.4, F2 score of 0.80 and area under the curve?receiver operating characteristic of 0.88, for a cut?off value of 300 cGy. The present study suggested that ML can be used to pre?select female Asian patients with low MHD who do not require DIBH for the postoperative RT of BC. en-copyright= kn-copyright= en-aut-name=KamizakiRyo en-aut-sei=Kamizaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Al?HammadWlla en-aut-sei=Al?Hammad en-aut-mei=Wlla kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TekikiNouha en-aut-sei=Tekiki en-aut-mei=Nouha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshizakaHinata en-aut-sei=Ishizaka en-aut-mei=Hinata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KurodaKazuhiro en-aut-sei=Kuroda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=BarhamMajd en-aut-sei=Barham en-aut-mei=Majd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SugiantoIrfan en-aut-sei=Sugianto en-aut-mei=Irfan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakamitsuYuki en-aut-sei=Nakamitsu en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HiranoMasaki en-aut-sei=Hirano en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MutoYuki en-aut-sei=Muto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=IharaHiroki en-aut-sei=Ihara en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=SugiyamaSoichi en-aut-sei=Sugiyama en-aut-mei=Soichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Interdisciplinary Sciences and Engineering in Health Systems, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Dentistry and Dental Surgery, College of Medicine and Health Sciences, An?Najah National University kn-affil= affil-num=11 en-affil=Department of Oral Radiology, Faculty of Dentistry, Hasanuddin University kn-affil= affil-num=12 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=15 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=16 en-affil=Department of Proton Beam Therapy, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=BC kn-keyword=BC en-keyword=RT kn-keyword=RT en-keyword=heart dose kn-keyword=heart dose en-keyword=ML kn-keyword=ML en-keyword=DNN kn-keyword=DNN en-keyword=DIBH kn-keyword=DIBH END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=19 article-no= start-page=3038 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Semaphorin 3A in Kidney Development and Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kidney diseases are worldwide public health problems affecting millions of people. However, there are still limited therapeutic options against kidney diseases. Semaphorin 3A (SEMA3A) is a secreted and membrane-associated protein, which regulates diverse functions, including immune regulation, cell survival, migration and angiogenesis, thus involving in the several pathogeneses of diseases, including eyes and neurons, as well as kidneys. SEMA3A is expressed in podocytes and tubular cells in the normal adult kidney, and recent evidence has revealed that excess SEMA3A expression and the subsequent signaling pathway aggravate kidney injury in a variety of kidney diseases, including nephrotic syndrome, diabetic nephropathy, acute kidney injury, and chronic kidney disease. In addition, several reports have demonstrated that the inhibition of SEMA3A ameliorated kidney injury via a reduction in cell apoptosis, fibrosis and inflammation; thus, SEMA3A may be a potential therapeutic target for kidney diseases. In this review article, we summarized the current knowledge regarding the role of SEMA3A in kidney pathophysiology and their potential use in kidney diseases. en-copyright= kn-copyright= en-aut-name=SangYizhen en-aut-sei=Sang en-aut-mei=Yizhen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=semaphorin 3A kn-keyword=semaphorin 3A en-keyword=neuropilin-1 kn-keyword=neuropilin-1 en-keyword=podocyte kn-keyword=podocyte en-keyword=diabetic nephropathy kn-keyword=diabetic nephropathy en-keyword=acute kidney injury kn-keyword=acute kidney injury en-keyword=chronic kidney injury kn-keyword=chronic kidney injury en-keyword=lupus nephritis kn-keyword=lupus nephritis en-keyword=fibrosis kn-keyword=fibrosis en-keyword=apoptosis kn-keyword=apoptosis en-keyword=inflammation kn-keyword=inflammation END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=727 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Increased quadriceps muscle strength after medial meniscus posterior root repair is associated with decreased medial meniscus extrusion progression en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background This study aimed to assess quadriceps muscle strength after medial meniscus (MM) posterior root repair and determine its relationship with clinical scores and MM extrusion (MME).
Methods Thirty patients who underwent pullout repair for MM posterior root tear and were evaluated for quadriceps muscle strength preoperatively and at 1 year postoperatively were included in this study. Quadriceps muscle strength was measured using the Locomo Scan-II instrument (ALCARE, Tokyo, Japan). MME and clinical scores (i.e., Knee Injury and Osteoarthritis Outcome Score [KOOS], International Knee Documentation Committee score, Lysholm score, Tegner score, and visual analog scale pain score) were evaluated preoperatively and at 1 year postoperatively, and second-look arthroscopy was performed at 1 year postoperatively. Wilcoxon ' s signed-rank test was used to compare each measure pre-and postoperatively. Pearson ' s correlation coefficient was used to assess the correlation with quadriceps muscle strength values. Multiple regression analysis was performed to identify factors associated with the change in MME (.MME).
Results Second-look arthroscopy confirmed continuity of the posterior root in all patients. The quadriceps muscle strength measured at 1 year postoperatively (355.1 +/- 116.2 N) indicated significant improvement relative to the quadriceps muscle strength measured preoperatively (271.9 +/- 97.4 N, p < 0.001). The MME at 1 year postoperatively (4.59 +/- 1.24 mm) had progressed significantly relative to the MME preoperatively (3.63 +/- 1.01 mm, p < 0.001). The clinical scores at 1 year postoperatively were improved significantly relative to the scores preoperatively (p < 0.001). The postoperative quadriceps muscle strength was correlated with.MME (correlation coefficient = -0.398, p = 0.030), and the change in quadriceps muscle strength was correlated with the KOOS-Quality of Life (correlation coefficient = 0.430, p = 0.018). Multiple regression analysis showed that the postoperative quadriceps muscle strength had a significant effect on.MME even when the body mass index and time from injury to surgery were included.
Conclusions After MM posterior root repair, patients with greater quadriceps muscle strength showed less MME progression. In addition, patients with greater improvement in quadriceps muscle strength had better clinical scores; therefore, continued rehabilitation aimed at improving quadriceps muscle strength after MM posterior root repair is recommended. en-copyright= kn-copyright= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukubaMikao en-aut-sei=Fukuba en-aut-mei=Mikao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigashiharaNaohiro en-aut-sei=Higashihara en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Clinical score kn-keyword=Clinical score en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Medial meniscus extrusion kn-keyword=Medial meniscus extrusion en-keyword=Muscle strength kn-keyword=Muscle strength en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Quadriceps kn-keyword=Quadriceps END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=4 article-no= start-page=81 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of cancer stroma for bone destruction in oral squamous cell carcinoma using different cancer stroma subtypes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Stromal cells in the tumor microenvironment (TME) can regulate the progression of numerous types of cancer; however, the bone invasion of oral squamous cell carcinoma (OSCC) has been poorly investigated. In the present study, the effect of verrucous SCC?associated stromal cells (VSCC?SCs), SCC?associated stromal cells (SCC?SCs) and human dermal fibroblasts on bone resorption and the activation of HSC?3 osteoclasts in vivo were examined by hematoxylin and eosin, AE1/3 (pan?cytokeratin) and tartrate?resistant acid phosphatase staining. In addition, the expression levels of matrix metalloproteinase (MMP)9, membrane?type 1 MMP (MT1?MMP), Snail, receptor activator of NF?κB ligand (RANKL) and parathyroid hormone?related peptide (PTHrP) in the bone invasion regions of HSC?3 cells were examined by immunohistochemistry. The results suggested that both SCC?SCs and VSCC?SCs promoted bone resorption, the activation of osteoclasts, and the expression levels of MMP9, MT1?MMP, Snail, RANKL and PTHrP. However, SCC?SCs had a more prominent effect compared with VSCC?SCs. Finally, microarray data were used to predict potential genes underlying the differential effects of VSCC?SCs and SCC?SCs on bone invasion in OSCC. The results revealed that IL1B, ICAM1, FOS, CXCL12, INS and NGF may underlie these differential effects. In conclusion, both VSCC?SCs and SCC?SCs may promote bone invasion in OSCC by enhancing the expression levels of RANKL in cancer and stromal cells mediated by PTHrP; however, SCC?SCs had a more prominent effect. These findings may represent a potential regulatory mechanism underlying the bone invasion of OSCC. en-copyright= kn-copyright= en-aut-name=ShanQiusheng en-aut-sei=Shan en-aut-mei=Qiusheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OoMay Wathone en-aut-sei=Oo en-aut-mei=May Wathone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InadaYasunori en-aut-sei=Inada en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FushimiShigeko en-aut-sei=Fushimi en-aut-mei=Shigeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma en-keyword=bone invasion kn-keyword=bone invasion en-keyword=osteoclast kn-keyword=osteoclast en-keyword=receptor activator of NF?κB ligand kn-keyword=receptor activator of NF?κB ligand en-keyword=parathyroid hormone?related peptide kn-keyword=parathyroid hormone?related peptide en-keyword=microarray kn-keyword=microarray en-keyword=cancer?associated stromal cells kn-keyword=cancer?associated stromal cells END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=1 article-no= start-page=18 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Data-driven model of the local wind field over two small lakes in Jyv?skyl?, Finland en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study presents a data-driven model of the local wind field over two small lakes in Jyv?skyl?, Finland. Five temporary monitoring stations installed during the summers of 2015 and 2016 observed wind speed/direction around the two lakes. In addition, an official meteorological station located 15 km north of the lakes is permanently available. Our goal was to develop a model that could evaluate wind speed and direction over the two lakes using only data from the permanent station. Statistical analysis for the spatio-temporal wind data revealed that (1) local wind speed is correlated with the elevation and its cyclic pattern is identical to that of the official-station data, and (2) the local wind direction field is spatially homogeneous and is strongly correlated with the official-station data. Based on these results, we built two regression models for estimating spatial distribution of local wind speed and directions based on the digital elevation model (DEM) and official-station data. We compared the predicted wind speeds/directions by the proposed model with the corresponding observation data and a numerical result for model validation. We found that the proposed model could effectively simulate heterogeneous local wind fields and considers uncertainty of estimates. en-copyright= kn-copyright= en-aut-name=ShukuTakayuki en-aut-sei=Shuku en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RopponenJanne en-aut-sei=Ropponen en-aut-mei=Janne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JuntunenJanne en-aut-sei=Juntunen en-aut-mei=Janne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuitoHiroshi en-aut-sei=Suito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Finnish Environment Institute SYKE, Jyv?skyl?

Although animal testing has long been used to evaluate skin sensitization, the recent trend to regulate such testing has led to the development and use of alternative methods. Skin sensitization reactions are summarized in the form of an adverse outcome pathway consisting of four key events (KE), including covalent binding to skin proteins (KE1), keratinocyte activation (KE2), and dendritic cell activation (KE3). Equivalent alternative methods have been developed for KE1 to KE3, but no valid alternative has yet been developed for the evaluation of KE4 and T?cell activation. Current alternative methods rely on data from KE1 to KE3 to predict the effect of chemicals on skin sensitization. The addition of KE4 data is expected to improve the accuracy and reproducibility of such predictions. The aim of this study was to establish an assay to evaluate KE4 T?cell activation to supplement data on skin sensitization related to KE4. To evaluate T?cell activation, the Jurkat T?cell line stably expressing luciferase downstream of the pro?inflammatory cytokine interleukin?2 promoter was used. After exposure to known skin sensitizing agents and control substances, luciferase activity measurements revealed that this assay was valid for evaluating skin sensitization. However, two skin sensitizers known to have immunosuppressive effects on T?cells reacted negatively in this assay. The results revealed that this assay simultaneously allows for monitoring of the skin sensitization and immuno?suppressiveness of chemical substances and supplements KE4 T?cell activation data, and may thus contribute to reducing the use of animal experiments. en-copyright= kn-copyright= en-aut-name=NagahataTaichi en-aut-sei=Nagahata en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujinoYoshio en-aut-sei=Tsujino en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakayamaEiji en-aut-sei=Takayama en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HikasaHaruka en-aut-sei=Hikasa en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Science, Technology and Innovation, Kobe University kn-affil= affil-num=3 en-affil=Department of Oral Biochemistry, Asahi University School of Dentistry kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=skin sensitization kn-keyword=skin sensitization en-keyword=immunotoxicity kn-keyword=immunotoxicity en-keyword=interleukin-2 promoter kn-keyword=interleukin-2 promoter en-keyword=Jurkat kn-keyword=Jurkat en-keyword=T-cell activation kn-keyword=T-cell activation END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=2 article-no= start-page=154 end-page=164 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of a Functionally Efficient and Thermally Stable Outward Sodium-Pumping Rhodopsin (BeNaR) from a Thermophilic Bacterium en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rhodopsins are transmembrane proteins with retinal chromophores that are involved in photo-energy conversion and photo-signal transduction in diverse organisms. In this study, we newly identified and characterized a rhodopsin from a thermophilic bacterium, Bellilinea sp. Recombinant Escherichia coli cells expressing the rhodopsin showed light-induced alkalization of the medium only in the presence of sodium ions (Na+), and the alkalization signal was enhanced by addition of a protonophore, indicating an outward Na+ pump function across the cellular membrane. Thus, we named the protein Bellilinea Na+-pumping rhodopsin, BeNaR. Of note, its Na+-pumping activity is significantly greater than that of the known Na+-pumping rhodopsin, KR2. We further characterized its photochemical properties as follows: (i) Visible spectroscopy and HPLC revealed that BeNaR has an absorption maximum at 524?nm with predominantly (>96%) the all-trans retinal conformer. (ii) Time-dependent thermal denaturation experiments revealed that BeNaR showed high thermal stability. (iii) The time-resolved flash-photolysis in the nanosecond to millisecond time domains revealed the presence of four kinetically distinctive photointermediates, K, L, M and O. (iv) Mutational analysis revealed that Asp101, which acts as a counterion, and Asp230 around the retinal were essential for the Na+-pumping activity. From the results, we propose a model for the outward Na+-pumping mechanism of BeNaR. The efficient Na+-pumping activity of BeNaR and its high stability make it a useful model both for ion transporters and optogenetics tools. en-copyright= kn-copyright= en-aut-name=KuriharaMarie en-aut-sei=Kurihara en-aut-mei=Marie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ThielVera en-aut-sei=Thiel en-aut-mei=Vera kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiHirona en-aut-sei=Takahashi en-aut-mei=Hirona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WardDavid M. en-aut-sei=Ward en-aut-mei=David M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BryantDonald A. en-aut-sei=Bryant en-aut-mei=Donald A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaiMakoto en-aut-sei=Sakai en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshizawaSusumu en-aut-sei=Yoshizawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SudoYuki en-aut-sei=Sudo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biological Sciences, Tokyo Metropolitan University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Science, Okayama University of Science kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Land Resources and Environmental Sciences, Montana State University kn-affil= affil-num=6 en-affil=Department of Biochemistry and Molecular Biology, The Pennsylvania State University kn-affil= affil-num=7 en-affil=Department of Chemistry, Graduate School of Science, Okayama University of Science kn-affil= affil-num=8 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=9 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=rhodopsin kn-keyword=rhodopsin en-keyword=ion transport kn-keyword=ion transport en-keyword=retinal kn-keyword=retinal en-keyword=isomerization kn-keyword=isomerization en-keyword=optogenetics kn-keyword=optogenetics END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=14 article-no= start-page=6367 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Interface Setup Optimization Method Using a Throughput Estimation Model for Concurrently Communicating Access Points in a Wireless Local Area Network en-subtitle= kn-subtitle= en-abstract= kn-abstract=The IEEE 802.11 wireless local-area network (WLAN) has been deployed around the globe as a major Internet access medium due to its low cost and high flexibility and capacity. Unfortunately, dense wireless networks can suffer from poor performance due to high levels of radio interference resulting from adjoining access points (APs). To address this problem, we studied the AP transmission power optimization method, which selects the maximum or minimum power supplied to each AP so that the average signal-to-interference ratio (SIR) among the concurrently communicating APs is maximized.However, this method requires measurements of receiving signal strength (RSS) under all the possible combinations of powers. It may need intolerable loads and time as the number of APs increases. It also only considers the use of channel bonding (CB), although non-CB sometimes achieves higher performance under high levels of interference. In this paper, we present an AP interface setup optimization method using the throughput estimation model for concurrently communicating APs. The proposed method selects CB or non-CB in addition to the maximum or minimum power for each AP. This model approach avoids expensive costs of RSS measurements under a number of combinations. To estimate the RSS at an AP from another AP or a host, the model needs the distance and the obstacles between them, such as walls. Then, by calculating the estimated RSS with the model and calculating the SIR from them, the AP interface setups for a lot of APs in a large-scale wireless network can be optimized on a computer in a very short time. For evaluation, we conducted extensive experiments using Raspberry Pi for APs and Linux PCs for hosts under 12 network topologies in three buildings at Okayama University, Japan, and Jatiya Kabi Kazi Nazrul Islam University, Bangladesh. The results confirm that the proposed method selects the best AP interface setup with the highest total throughput in any topology. en-copyright= kn-copyright= en-aut-name=AkhterFatema en-aut-sei=Akhter en-aut-mei=Fatema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HtetEi Ei en-aut-sei=Htet en-aut-mei=Ei Ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WuBin en-aut-sei=Wu en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KongDezheng en-aut-sei=Kong en-aut-mei=Dezheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FangShihao en-aut-sei=Fang en-aut-mei=Shihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=wireless local area network kn-keyword=wireless local area network en-keyword=signal-to-interference ratio kn-keyword=signal-to-interference ratio en-keyword=interface setup optimization kn-keyword=interface setup optimization en-keyword=throughput estimation model kn-keyword=throughput estimation model en-keyword=channel bonding kn-keyword=channel bonding END start-ver=1.4 cd-journal=joma no-vol=154 cd-vols= no-issue=1 article-no= start-page=169 end-page=179 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low frequency of intracranial progression in advanced NSCLC patients treated with cancer immunotherapies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intracranial metastases are common in nonsmall-cell lung cancer (NSCLC) patients, whose prognosis is very poor. In addition, intracranial progression is common during systemic treatments due to the inability to penetrate central nervous system (CNS) barriers, whereas the intracranial effects of cancer immunotherapies remain unclear. We analyzed clinical data to evaluate the frequency of intracranial progression in advanced NSCLC patients treated with PD-1 blockade therapies compared with those treated without PD-1 blockade therapies, and found that the frequency of intracranial progression in advanced NSCLC patients treated with PD-1 blockade therapies was significantly lower than that in patients treated with cytotoxic chemotherapies. In murine models, intracranial rechallenged tumors after initial rejection by PD-1 blockade were suppressed. Accordingly, long-lived memory precursor effector T cells and antigen-specific T cells were increased by PD-1 blockade in intracranial lesions. However, intracranial rechallenged different tumors are not suppressed. Our results indicate that cancer immunotherapies can prevent intracranial progression, maintaining long-term effects intracranially as well as systemically. If intracranial recurrence occurs during the treatment with PD-1 blockade therapies, aggressive local therapies could be worthwhile. en-copyright= kn-copyright= en-aut-name=KemmotsuNaoya

plant?microbe interactions. The ability of microbes to decompose cell wall polysaccharides contributes to microbial pathogenicity. Plants have evolved mechanisms to prevent cell wall degradation. However, the role of the cell wall in plant?microbe interactions is not well understood. Here, we discuss four functions of the plant cell wall?physical defence, storage of antimicrobial compounds, production of cell wall-derived elicitors, and provision of carbon sources?in the context of plant?microbe interactions. In addition, we discuss the four families of cell surface receptors associated with plant cell walls (malectin-like receptor kinase family, wall-associated kinase family, leucine-rich repeat receptor-like kinase family, and lysin motif receptor-like kinase family) that have been the subject of several important studies in recent years. This review summarises the findings on both plant cell wall and plant immunity, improving our understanding and may provide impetus to various researchers. en-copyright= kn-copyright= en-aut-name=IshidaKonan en-aut-sei=Ishida en-aut-mei=Konan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Biochemistry, University of Cambridge kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Plant cell wall kn-keyword=Plant cell wall en-keyword=Plant?microbe interaction kn-keyword=Plant?microbe interaction en-keyword=Cell wall integrity kn-keyword=Cell wall integrity en-keyword=Receptor-like kinase kn-keyword=Receptor-like kinase en-keyword=Plant immunity kn-keyword=Plant immunity END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=10 article-no= start-page=2339 end-page=2345 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synergic effect of graphene oxide and boron nitride on the mechanical properties of polyimide composite films en-subtitle= kn-subtitle= en-abstract= kn-abstract=The addition of two-dimensional (2D) materials into polymers can improve their mechanical properties. In particular, graphene oxide (GO) and hexagonal boron nitride (h-BN) are expected to be potential nanoplatelet additives for polymers. Interactions between such nanoplatelets and polymers are effective in improving the above properties. However, no report has investigated the effect of using two types of nanoplatelets that have good interaction with polymers. In this study, we fabricated polyimide (PI) films that contain two types of nanoplatelets, amine-functionalized h-BN (BNNH2) and GO. We have elucidated that the critical ratio and the content of BNNH2 and GO within PI govern the films' mechanical properties. When the BNNH2/GO weight ratio was 52?:?1 and their content was 1 wt% in the PI film, the tensile modulus and tensile strength were increased by 155.2 MPa and 4.2 GPa compared with the pristine PI film. en-copyright= kn-copyright= en-aut-name=ChengYi Kai en-aut-sei=Cheng en-aut-mei=Yi Kai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Camp?onBeno?t Denis Louis en-aut-sei=Camp?on en-aut-mei=Beno?t Denis Louis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObataSeiji en-aut-sei=Obata en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Core for Interdisciplinary Sciences, Okayama University kn-affil= affil-num=3 en-affil=Research Core for Interdisciplinary Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=18 article-no= start-page=2059 end-page=2066 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Incremental prognostic value of non-alcoholic fatty liver disease over coronary computed tomography angiography findings in patients with suspected coronary artery disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims This study aimed to investigate additional risk stratification benefits of hepatic steatosis (HS) concurrently assessed during coronary computed tomography angiography (CTA) in a large patient cohort with suspected stable coronary artery disease (CAD).
Methods and results In this prospective study, 1148 Japanese outpatients without a history of CAD who underwent coronary CTA for suspected stable CAD (mean age 64?±?14?years) were included. HS, defined on CT as a hepatic-to-spleen attenuation ratio of <1.0, was examined just before the evaluation of adverse CTA findings, defined as obstructive and/or high-risk plaque. The major adverse cardiac events (MACE) were the composite of cardiac death, acute coronary syndrome, and late revascularization. The incremental predictive value of HS was evaluated using the global χ2 test and C-statistic. HS was identified in 247 (22%) patients. During a median follow-up of 3.9?years, MACE was observed in 40 (3.5%) patients. HS was significantly associated with MACE in a model that included adverse CTA findings (hazard ratio 4.01, 95% confidence interval 2.12?7.59, P? Conclusion In patients with suspected stable CAD, concurrent evaluation of HS during coronary CTA enables more accurate detection of patients at higher risk of MACE. en-copyright= kn-copyright= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiTakashi en-aut-sei=Miki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TodaHironobu en-aut-sei=Toda en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EjiriKentaro en-aut-sei=Ejiri en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Coronary artery disease kn-keyword=Coronary artery disease en-keyword=Computed tomography angiography kn-keyword=Computed tomography angiography en-keyword=Atherosclerotic plaque kn-keyword=Atherosclerotic plaque en-keyword=Risk assessment kn-keyword=Risk assessment en-keyword=Hepatic steatosis kn-keyword=Hepatic steatosis END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resection of Orbital Myxoma With Magnetic Resonance Imaging Evidence of Ethmoid Sinus Origin: Case Report and Review of 20 Patients in the Literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 41-year-old woman showed a palpable mass at the superonasal orbital edge on the right side. Magnetic resonance imaging demonstrated a lobulated fluid-containing tubular mass which extended anteriorly to posteriorly along the medial orbital wall, nasal to the eyeball. She was followed once a year for 8 years until the age of 49 years when she decided to undergo surgical resection because of the enlarged mass. The lobulated large mass was resected and the pathology showed sparsely distributed spindle cells, positive for CD34, in alcian blue-positive mucous substances, indicative of myxoma. Postoperative magnetic resonance imaging showed residual lobulated tubular mass along the optic nerve on the medial side and superior to the eyeball. The residual orbital mass showed stable structure with more evident connection with the ethmoid sinus lesion, suggestive of the ethmoid origin, in 12 years until the age of 61 years. In the review of 20 patients with orbital myxomas in the literature, in addition to this case, roughly classified locations in the orbit were retrobulbar in 8 patients, on the lateral side of the orbit in 4, on the superior side in 6, on the medial side in 1 (this patient), and in the orbit with no specific description in 2. In pathological examinations, immunohistochemistry was not done in 8 patients, done but all negative in 2, and positive in 11 patients: nerve sheath myxoma was diagnosed in 3 patients based on positive S100 staining. Orbital myxoma is rare but considered in differential diagnosis of orbital masses. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= en-keyword=myxoma kn-keyword=myxoma en-keyword=orbital kn-keyword=orbital en-keyword=CD34 kn-keyword=CD34 en-keyword=ethmoid sinus kn-keyword=ethmoid sinus en-keyword=literature review kn-keyword=literature review END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=e1579 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Echelon analysis and its software for spatial lattice data en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we explore the use of echelon analysis and its software named EcheScan for spatial lattice data. EcheScan is developed as a web application via an internet browser in R language and Shiny server for echelon analysis. The technique of echelon is proposed to analyze the topological structure for spatial lattice data. The echelon tree provides a dendrogram representation. Regional features, such as hierarchical spatial data structure and hotspots clusters, are shown in an echelon dendrogram. In addition, we introduce the conception of echelon with the values and neighbors for lattice data. We also explain the use of EcheScan for one- and two-dimensional regular lattice data. Furthermore, coronavirus disease 2019 death data corresponding to 50 US states are illustrated using EcheScan as an example of geospatial lattice data.

In this study, we used an animal model with pathological changes that mimics artery wall damage caused by stent retrievers in humans. We injected hCB-EPCs to investigate their effect on endothelial hyperplasia and dysfunction during intimal repair. Four groups were established based on the length of reperfusion (3 and 28 days), as well as the presence or absence of hCB-EPC therapy. Damage to the internal carotid artery was evaluated by hematoxylin-eosin and immunohistochemical staining. Stroke volume was not significantly different between non-EPC and EPC groups although EPC treatment alleviated intimal hyperplasia 28 days after intimal damage. Vascular endothelial growth factor (VEGF) and eNOS expression were significantly higher in the EPC-treated group than in the non-EPC group 3 days after intimal damage. In addition, MMP9 and 4HNE expression in the EPC-treated group was significantly lower than in the non-EPC group. Ultimately, this study found that venous transplantation of hCB-EPCs could inhibit neointimal hyperplasia, alleviate endothelial dysfunction, suppress intimal inflammation, and reduce oxidative stress during healing of intimal damage. en-copyright= kn-copyright= en-aut-name=SunHongming en-aut-sei=Sun en-aut-mei=Hongming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FengTian en-aut-sei=Feng en-aut-mei=Tian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BianZhihong en-aut-sei=Bian en-aut-mei=Zhihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YuHaibo en-aut-sei=Yu en-aut-mei=Haibo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HuXiao en-aut-sei=Hu en-aut-mei=Xiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HuXinran en-aut-sei=Hu en-aut-mei=Xinran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BianYuting en-aut-sei=Bian en-aut-mei=Yuting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasakiRyo en-aut-sei=Sasaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FukuiYusuke en-aut-sei=Fukui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakemotoMami en-aut-sei=Takemoto en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=National Center Hospital, National Center of Neurology and Psychiatry kn-affil= affil-num=15 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ischemic stroke kn-keyword=ischemic stroke en-keyword=human cord blood-endothelial progenitor cells kn-keyword=human cord blood-endothelial progenitor cells en-keyword=mechanical thrombectomy kn-keyword=mechanical thrombectomy en-keyword=intimal hyperplasia kn-keyword=intimal hyperplasia END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=8 article-no= start-page=1368 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230729 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microstructural Control and Alloy Design for Improving the Resistance to Delayed Fracture of Ultrahigh-Strength Automotive Steel Sheets en-subtitle= kn-subtitle= en-abstract= kn-abstract=The demand for higher-strength automotive steel sheets has increased significantly for lightweight and safe body concepts. However, the increment of the steel strength is often limited by the potential occurrence of delayed fracture. This paper discusses proper microstructure control and alloy design to improve the resistance against the delayed fracture of ultrahigh-strength automotive steel sheets in order to increase the usable upper limit of their strength and provides basic data serving as a practical guide for solving the problem of delayed fracture in ultrahigh-strength automotive steel sheets. It is confirmed that grain refinement, the appropriate dual-phase structure of martensite with ferrite or retained austenite, and surface decarburization, increase the resistance to delayed fracture. In terms of alloy design, the effects of Nb, Mo, and B on the delayed fracture resistance of hot-stamped steels have been investigated. The results suggest that there are other reasons for Nb to improve delayed fracture resistance in addition to grain refinement and the ability to trap hydrogen by its precipitates, as has been conventionally believed. Regarding Mo, it was clearly demonstrated that the segregation of this element at the grain boundary plays a main role in improving the delayed fracture resistance. en-copyright= kn-copyright= en-aut-name=SenumaTakehide en-aut-sei=Senuma en-aut-mei=Takehide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MohrbacherHardy en-aut-sei=Mohrbacher en-aut-mei=Hardy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= affil-num=3 en-affil=NiobelCon BV kn-affil= en-keyword=delayed fracture kn-keyword=delayed fracture en-keyword=hydrogen embrittlement kn-keyword=hydrogen embrittlement en-keyword=high-strength steel kn-keyword=high-strength steel en-keyword=automotive steel sheets kn-keyword=automotive steel sheets en-keyword=microstructural control kn-keyword=microstructural control en-keyword=alloy design kn-keyword=alloy design END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=8 article-no= start-page=e19038 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bayesian statistical modeling to predict observer-specific optimal windowing parameters in magnetic resonance imaging en-subtitle= kn-subtitle= en-abstract= kn-abstract=Magnetic resonance (MR) images require a process known as windowing for optimizing the display conditions. However, the conventional windowing process often fails to achieve the preferred display conditions for observers due to various factors. This study proposes a novel framework for predicting the preferred windowing parameters for each observer using Bayesian statistical modeling. MR images obtained from 1000 patients were divided into training and test sets at a 7:3 ratio. The image intensity and windowing parameters were standardized using previously reported methods. Bayesian statistical modeling was utilized to predict the windowing parameters preferred by three MR imaging (MRI) operators. The performance of the proposed framework was evaluated by assessing the mean relative error (MRE), mean absolute error (MAE), and Pearson's correlation coefficient (ρ) of the test set. In addition, the naive method, which presumes that the average value of the windowing parameters for each acquisition sequence and body region in the training set is optimal, was also used for comparison. Three MRI operators and three radiologists conducted visual assessments. The mean MRE, MAE, and ρ values for the window level and width (WL/WW) in the proposed framework were 12.6 and 13.9, 42.9 and 85.4, and 0.98 and 0.98, respectively. These results outperformed those obtained using the naive method. The visual assessments revealed no significant differences between the original and predicted display conditions, indicating that the proposed framework accurately predicts individualized windowing parameters with the additional advantages of robustness and ease of use. Thus, the proposed framework can effectively predict the windowing parameters preferred by each observer. en-copyright= kn-copyright= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= en-keyword=MR image kn-keyword=MR image en-keyword=Image intensity standardization kn-keyword=Image intensity standardization en-keyword=Windowing kn-keyword=Windowing en-keyword=Prediction kn-keyword=Prediction en-keyword=Bayesian statistical modeling kn-keyword=Bayesian statistical modeling END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue= article-no= start-page=e47798 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230810 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessing Vulnerability to Surges in Suicide-Related Tweets Using Japan Census Data: Case-Only Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: As the use of social media becomes more widespread, its impact on health cannot be ignored. However, limited research has been conducted on the relationship between social media and suicide. Little is known about individuals’ vulnerable to suicide, especially when social media suicide information is extremely prevalent.
Objective: This study aims to identify the characteristics underlying individuals’ vulnerability to suicide brought about by an increase in suicide-related tweets, thereby contributing to public health.
Methods: A case-only design was used to investigate vulnerability to suicide using individual data of people who died by suicide and tweet data from January 1, 2011, through December 31, 2014. Mortality data were obtained from Japanese government statistics, and tweet data were provided by a commercial service. Tweet data identified the days when suicide-related tweets surged, and the date-keyed merging was performed by considering 3 and 7 lag days. For the merged data set for analysis, the logistic regression model was fitted with one of the personal characteristics of interest as a dependent variable and the dichotomous exposure variable. This analysis was performed to estimate the interaction between the surges in suicide-related tweets and personal characteristics of the suicide victims as case-only odds ratios (ORs) with 95% CIs. For the sensitivity analysis, unexpected deaths other than suicide were considered.
Results: During the study period, there were 159,490 suicides and 115,072 unexpected deaths, and the number of suicide-related tweets was 2,804,999. Following the 3-day lag of a highly tweeted day, there were significant interactions for those who were aged 40 years or younger (OR 1.09, 95% CI 1.03-1.15), male (OR 1.12, 95% CI 1.07-1.18), divorced (OR 1.11, 95% CI 1.03 1.19), unemployed (OR 1.12, 95% CI 1.02-1.22), and living in urban areas (OR 1.26, 95% CI 1.17 1.35). By contrast, widowed individuals had significantly lower interactions (OR 0.83, 95% CI 0.77-0.89). Except for unemployment, significant relationships were also observed for the 7-day lag. For the sensitivity analysis, no significant interactions were observed for other unexpected deaths in the 3-day lag, and only the widowed had a significantly larger interaction than those who were married (OR 1.08, 95% CI 1.02-1.15) in the 7-day lag.
Conclusions: This study revealed the interactions of personal characteristics associated with susceptibility to suicide-related tweets. In addition, a few significant relationships were observed in the sensitivity analysis, suggesting that such an interaction is specific to suicide deaths. In other words, individuals with these characteristics, such as being young, male, unemployed, and divorced, may be vulnerable to surges in suicide-related tweets. Thus, minimizing public health strain by identifying people who are vulnerable and susceptible to a surge in suicide-related information on the internet is necessary. en-copyright= kn-copyright= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=case-only approach kn-keyword=case-only approach en-keyword=mass media kn-keyword=mass media en-keyword=public health kn-keyword=public health en-keyword=social media kn-keyword=social media en-keyword=suicidal risk kn-keyword=suicidal risk en-keyword=suicide prevention kn-keyword=suicide prevention en-keyword=suicide kn-keyword=suicide en-keyword=suicide-related tweets kn-keyword=suicide-related tweets en-keyword=Twitter kn-keyword=Twitter END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=e33 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210907 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recent advances regarding endoscopic biliary drainage for unresectable malignant hilar biliary obstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biliary drainage for unresectable malignant hilar biliary obstruction (UMHBO) is still associated with a number of controversies to be resolved. The superiority of bilateral drainage in comparison to unilateral drainage has not been proven obviously yet. However, bilateral drainage is necessary to treat obstructive jaundice in some UMHBO patients, and this may be connected with preservation of the functional liver volume. The partial stent-in-stent (SIS) method and side-by-side (SBS) method developed as bilateral drainage methods. There is no significant difference in the technical or clinical success rates of the SIS and SBS methods. In addition, these methods are comparable in terms of adverse events, patency period, and survival period. On the other hand, reintervention for recurrent biliary obstruction (RBO) after the SBS method seems to be easier in comparison to cases with RBO after the SIS method; however, there is no remarkable difference in the clinical results of these procedures. Endoscopic ultrasound (EUS)-guided biliary drainage also has become an option for patients with UMHBO. Left hepatic drainage using EUS-guided hepaticogastrostomy (EUS-HGS) has become common; however, few studies have reported the results of bridging drainage for the right lobe using the EUS-HGS route or EUS-guided hepaticojejunostomy. A few studies addressed the results of newly designed stents, such as the 6-mm braided metal stent and inside stent. The development of various drainage methods and new devices is necessary for the further advancement of endoscopic biliary drainage for patients with UMHBO, further studies to evaluate those methods and devices are warranted. en-copyright= kn-copyright= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=biliary drainage kn-keyword=biliary drainage en-keyword=EUS-BD kn-keyword=EUS-BD en-keyword=malignant hilar biliary obstruction kn-keyword=malignant hilar biliary obstruction en-keyword=side-by-side kn-keyword=side-by-side en-keyword=stent-in-stent kn-keyword=stent-in-stent END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=7 article-no= start-page=e0288175 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Augmented reality-based affective training for improving care communication skill and empathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=It is important for caregivers of people with dementia (PwD) to have good patient communication skills as it has been known to reduce the behavioral and psychological symptoms of dementia (BPSD) of PwD as well as caregiver burnout. However, acquiring such skills often requires one-on-one affective training, which can be costly. In this study, we propose affective training using augmented reality (AR) for supporting the acquisition of such skills. The system uses see-through AR glasses and a nursing training doll to train the user in both practical nursing skills and affective skills such as eye contact and patient communication. The experiment was conducted with 38 nursing students. The participants were assigned to either the Doll group, which only used a doll for training, or the AR group, which used both a doll and the AR system. The results showed that eye contact significantly increased and the face-to-face distance and angle decreased in the AR group, while the Doll group had no significant difference. In addition, the empathy score of the AR group significantly increased after the training. Upon analyzing the correlation between personality and changes of physical skills, we found a significant positive correlation between the improvement rate of eye contact and extraversion in the AR group. These results demonstrated that affective training using AR is effective for improving caregivers' physical skills and their empathy for their patients. We believe that this system will be beneficial not only for dementia caregivers but for anyone looking to improve their general communication skills. en-copyright= kn-copyright= en-aut-name=NakazawaAtsushi en-aut-sei=Nakazawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamotoMiyuki en-aut-sei=Iwamoto en-aut-mei=Miyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurazumeRyo en-aut-sei=Kurazume en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NunoiMasato en-aut-sei=Nunoi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiMasaki en-aut-sei=Kobayashi en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HondaMiwako en-aut-sei=Honda en-aut-mei=Miwako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Advanced Fibro-Science, Kyoto Institute of Technology kn-affil= affil-num=3 en-affil=Faculty of Information Science and Electrical Engineering, Kyushu University kn-affil= affil-num=4 en-affil=School of Human Sciences, Sugiyama Jogakuen University kn-affil= affil-num=5 en-affil=Division of geriatric medicine, Rochester Regional Health System kn-affil= affil-num=6 en-affil=Division of Geriatric Research, National Hospital Organization Tokyo Medical Center kn-affil= END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=82024 end-page=82036 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and Analysis of Hybrid-Excitation Variable Flux Memory Motor for Traction Applications: Improving Output Power in High-Speed Area During Six-Step Operation Mode en-subtitle= kn-subtitle= en-abstract= kn-abstract=Variable flux motors with adjustable magnetic flux have been gaining attention because of their capability to simultaneously achieve a high torque density and high efficiency. In addition, the output power characteristic, which is related to acceleration performance, in high-speed areas is important in traction applications. However, typical traction motors have lower output power in high-speed areas. In this paper, a Hybrid-Excitation Variable Flux Memory Motor (HE-VFMM) is therefore proposed to enhance output power characteristics under six-step operation mode in high-speed area. The proposed HE-VFMM can perform magnetic flux adjustment with two components: field winding and variable flux permanent magnet (VPM), thus dramatically increasing flux adjustment range. The simulation results show the proposed HE-VFMM achieves 23.7% higher output power at 17,000 rpm than that of an existing traction motor in Prius 4th generation that has the same size while maintaining high efficiency in the frequently used operating area. Additionally, it was found that variable magnetic flux is very effective in enhancing the output power, especially in the high-speed region because the magnetic saturation in the stator core is mitigated by field-weakening control. Consequently, as the rotational speed increases, an increase ratio of the output power caused by the adjustable magnetic flux becomes higher. This paper shows that the proposed HE-VFMM is an effective method for improving the problem of low output power in high-speed regions in traction motors. en-copyright= kn-copyright= en-aut-name=TsunataRen en-aut-sei=Tsunata en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokomichiKeito en-aut-sei=Yokomichi en-aut-mei=Keito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakemotoMasatsugu en-aut-sei=Takemoto en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImaiJun en-aut-sei=Imai en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Variable flux memory motor kn-keyword=Variable flux memory motor en-keyword=hybrid excitation motor kn-keyword=hybrid excitation motor en-keyword=traction applications kn-keyword=traction applications en-keyword=EV kn-keyword=EV en-keyword=HEV kn-keyword=HEV en-keyword=six-step operation kn-keyword=six-step operation en-keyword=one-pulse drive kn-keyword=one-pulse drive en-keyword=output power density kn-keyword=output power density END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=15 article-no= start-page=2215 end-page=2221 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Co-occurrence of Three Systemic Diseases: ANCA-associated Vasculitis, Sjogren's syndrome and Sarcoidosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), Sjogren's syndrome (SjS), and sarcoidosis are systemic diseases targeting multiple organs.

Standard markers reflecting liver fibrosis, including the FIB-4 index, increase with age. This study aimed to identify fibrosis progression-related markers that are diagnostically beneficial even in aged individuals. Serum levels of pro- and anti-inflammatory cytokines were measured by multiple enzyme-linked immunosorbent assay. Two standard NAFLD or fibrosis progression-related markers ? the FIB-4 index and APRI score ? were analyzed along with cytokine levels to define the best approach to discriminate advanced fibrosis. Ninety-eight NAFLD patients were enrolled: 59 and 39 patients with fibrosis stages 1-2 and 3-4 respectively. In addition to the FIB-4 index and APRI score, the following factors showed significant differences between stages 1-2 and stages 3-4 in a multivariate analysis: platelet counts, IP-10, and RANTES. The fibrosis stage, FIB-4, APRI, PDGF-BB, and RANTES were related to the prognosis. In aged patients, IP-10, GM-CSF, and RANTES differed between stages 1-2 and stages 3-4. FIB-4 and APRI were beneficial for their correlation with fibrosis. However, to stratify either young or elderly advanced fibrosis patients, and to identify patients likely to have a bad outcome, RANTES was the best marker. en-copyright= kn-copyright= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiYasuto en-aut-sei=Takeuchi en-aut-mei=Yasuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaNozomu en-aut-sei=Wada en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OyamaAtsushi en-aut-sei=Oyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AdachiTakuya en-aut-sei=Adachi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=NAFLD kn-keyword=NAFLD en-keyword=NASH kn-keyword=NASH en-keyword=liver fibrosis kn-keyword=liver fibrosis en-keyword=chemokine kn-keyword=chemokine en-keyword=FIB-4 kn-keyword=FIB-4 END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=9 article-no= start-page=e13324 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neuropeptidergic control circuits in the spinal cord for male sexual behaviour: Oxytocin?gastrin‐releasing peptide systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=The neuropeptidergic mechanisms controlling socio-sexual behaviours consist of complex neuronal circuitry systems in widely distributed areas of the brain and spinal cord. At the organismal level, it is now becoming clear that “hormonal regulations” play an important role, in addition to the activation of neuronal circuits. The gastrin-releasing peptide (GRP) system in the lumbosacral spinal cord is an important component of the neural circuits that control penile reflexes in rats, circuits that are commonly referred to as the “spinal ejaculation generator (SEG).” Oxytocin, long known as a neurohypophyseal hormone, is now known to be involved in the regulation of socio-sexual behaviors in mammals, ranging from social bonding to empathy. However, the functional interaction between the SEG neurons and the hypothalamo-spinal oxytocin system remains unclear. Oxytocin is known to be synthesised mainly in hypothalamic neurons and released from the posterior pituitary into the circulation. Oxytocin is also released from the dendrites of the neurons into the hypothalamus where they have important roles in social behaviours via non-synaptic volume transmission. Because the most familiar functions of oxytocin are to regulate female reproductive functions including parturition, milk ejection, and maternal behaviour, oxytocin is often thought of as a “feminine” hormone. However, there is evidence that a group of parvocellular oxytocin neurons project to the lower spinal cord and control male sexual function in rats. In this report, we review the functional interaction between the SEG neurons and the hypothalamo-spinal oxytocin system and effects of these neuropeptides on male sexual behaviour. Furthermore, we discuss the finding of a recently identified, localised “volume transmission” role of oxytocin in the spinal cord. Findings from our studies suggest that the newly discovered “oxytocin-mediated spinal control of male sexual function” may be useful in the treatment of erectile and ejaculatory dysfunction. en-copyright= kn-copyright= en-aut-name=OtiTakumi en-aut-sei=Oti en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=gastrin-releasing peptide kn-keyword=gastrin-releasing peptide en-keyword=male sexual function kn-keyword=male sexual function en-keyword=non-synaptic volume transmission kn-keyword=non-synaptic volume transmission en-keyword=oxytocin kn-keyword=oxytocin en-keyword=spinal cord kn-keyword=spinal cord END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=7 article-no= start-page=895 end-page=908 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High Expression of MHC Class I Overcomes Cancer Immunotherapy Resistance Due to IFNγ Signaling Pathway Defects en-subtitle= kn-subtitle= en-abstract= kn-abstract=IFNγ signaling pathway defects are well-known mechanisms of resistance to immune checkpoint inhibitors. However, conflicting data have been reported, and the detailed mechanisms remain unclear. In this study, we have demonstrated that resistance to immune checkpoint inhibitors owing to IFNγ signaling pathway defects may be primarily caused by reduced MHC-I expression rather than by the loss of inhibitory effects on cellular proliferation or decreased chemokine production. In particular, we found that chemokines that recruit effector T cells were mainly produced by immune cells rather than cancer cells in the tumor microenvironment of a mouse model, with defects in IFNγ signaling pathways. Furthermore, we found a response to immune checkpoint inhibitors in a patient with JAK-negative head and neck squamous cell carcinoma whose HLA-I expression level was maintained. In addition, CRISPR screening to identify molecules associated with elevated MHC-I expression independent of IFNγ signaling pathways demonstrated that guanine nucleotide-binding protein subunit gamma 4 (GNG4) maintained MHC-I expression via the NF-κB signaling pathway. Our results indicate that patients with IFNγ signaling pathway defects are not always resistant to immune checkpoint inhibitors and highlight the importance of MHC-I expression among the pathways and the possibility of NF-κB?targeted therapies to overcome such resistance. en-copyright= kn-copyright= en-aut-name=KawaseKatsushige en-aut-sei=Kawase en-aut-mei=Katsushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawashimaShusuke en-aut-sei=Kawashima en-aut-mei=Shusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InozumeTakashi en-aut-sei=Inozume en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanjiEtsuko en-aut-sei=Tanji en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawazuMasahito en-aut-sei=Kawazu en-aut-mei=Masahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HanazawaToyoyuki en-aut-sei=Hanazawa en-aut-mei=Toyoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Cell Therapy, Chiba Cancer Center Research Institute kn-affil= affil-num=2 en-affil=Division of Cell Therapy, Chiba Cancer Center Research Institute kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Cell Therapy, Chiba Cancer Center Research Institute kn-affil= affil-num=5 en-affil=Division of Cell Therapy, Chiba Cancer Center Research Institute kn-affil= affil-num=6 en-affil=Division of Cell Therapy, Chiba Cancer Center Research Institute kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology/Head & Neck Surgery, Graduate School of Medicine, Chiba University kn-affil= affil-num=8 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=19 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcome of unlinked total elbow arthroplasty for rheumatoid arthritis in patients younger than 50 years old en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims
There are concerns regarding complications and longevity of total elbow arthroplasty (TEA) in young patients, and the few previous publications are mainly limited to reports on linked elbow devices. We investigated the clinical outcome of unlinked TEA for patients aged less than 50 years with rheumatoid arthritis (RA).
Methods
We retrospectively reviewed the records of 26 elbows of 21 patients with RA who were aged less than 50 years who underwent primary TEA with an unlinked elbow prosthesis. The mean patient age was 46 years (35 to 49), and the mean follow-up period was 13.6 years (6 to 27). Outcome measures included pain, range of motion, Mayo Elbow Performance Score (MEPS), radiological evaluation for radiolucent line and loosening, complications, and revision surgery with or without implant removal.
Results
The mean MEPS significantly improved from 47 (15 to 70) points preoperatively to 95 (70 to 100) points at final follow-up (p < 0.001). Complications were noted in six elbows (23%) in six patients, and of these, four with an ulnar neuropathy and one elbow with postoperative traumatic fracture required additional surgeries. There was no revision with implant removal, and there was no radiological evidence of loosening around the components. With any revision surgery as the endpoint, the survival rates up to 25 years were 78.1% (95% confidence interval 52.8 to 90.6) as determined by Kaplan-Meier analysis.
Conclusion
The clinical outcome of primary unlinked TEA for young patients with RA was satisfactory and comparable with that for elderly patients. A favourable survival rate without implant removal might support the use of unlinked devices for young patients with this disease entity, with a caution of a relatively high complication rate regarding ulnar neuropathy. en-copyright= kn-copyright= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashizumeKenzo en-aut-sei=Hashizume en-aut-mei=Kenzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkitaShunji en-aut-sei=Okita en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InoueHajime en-aut-sei=Inoue en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Chugoku Central Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Intelligent Orthopaedic System, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Total elbow arthroplasty kn-keyword=Total elbow arthroplasty en-keyword=Rheumatoid arthritis kn-keyword=Rheumatoid arthritis en-keyword=Unlinked elbow kn-keyword=Unlinked elbow en-keyword=Less than fifty years old kn-keyword=Less than fifty years old END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sugar signals from oral glucose transporters elicit cephalic-phase insulin release in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cephalic-phase insulin release (CPIR) occurs before blood glucose increases after a meal. Although glucose is the most plausible cue to induce CPIR, peripheral sensory systems involved are not fully elucidated. We therefore examined roles of sweet sensing by a T1R3-dependent taste receptor and sugar sensing by oral glucose transporters in the oropharyngeal region in inducing CPIR. Spontaneous oral ingestion of glucose significantly increased plasma insulin 5 min later in wild-type (C57BL/6) and T1R3-knockout mice, but intragastric infusion did not. Oral treatment of glucose transporter inhibitors phlorizin and phloretin significantly reduced CPIR after spontaneous oral ingestion. In addition, a rapid increase in plasma insulin was significantly smaller in WT mice with spontaneous oral ingestion of nonmetabolizable glucose analog than in WT mice with spontaneous oral ingestion of glucose. Taken together, the T1R3-dependent receptor is not required for CPIR, but oral glucose transporters greatly contribute to induction of CPIR by sugars. en-copyright= kn-copyright= en-aut-name=TakamoriMitsuhito en-aut-sei=Takamori en-aut-mei=Mitsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EgusaMasahiko en-aut-sei=Egusa en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=The Center for Special Needs Dentistry, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cephalic-phase insulin response kn-keyword=Cephalic-phase insulin response en-keyword=Glucose transporters kn-keyword=Glucose transporters en-keyword=Glucose kn-keyword=Glucose en-keyword=Sweet taste receptor kn-keyword=Sweet taste receptor en-keyword=Food intake kn-keyword=Food intake END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=1067 end-page=1083 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of genetic diversity and population structure in Cambodian melon landraces using molecular markers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Genetic diversity of Cambodian melons was evaluated by the analysis of 12 random amplified polymorphic DNA (RAPD) and 7 simple sequence repeat (SSR) markers using 62 accessions of melon landraces and compared with 231 accessions from other areas for genetic characterization of Cambodian melons. Among 62 accessions, 56 accessions were morphologically classified as small-seed type with seed lengths shorter than 9 mm, as in the horticultural groups Conomon and Makuwa. Gene diversity of Cambodian melons was 0.228, which was equivalent to those of the groups Conomon and Makuwa and smaller than those of Vietnamese and Central Asian landraces. A phylogenetic tree constructed from a genetic distance matrix classified 293 accessions into three major clusters. Small-seed type accessions from East and Southeast Asia formed clusters I and II, which were distantly related with cluster III consisting of large-seed type melon from other areas. All Cambodian melons belonged to cluster I (except three accessions) along with those from Thailand, Myanmar, Yunnan (China), and Vietnam (“Dua thom” in the northwest), thus indicating genetic similarity in these areas. In addition, the Cambodian melons were not differentiated among geographical populations. Conomon and Makuwa were classified into cluster II, together with melon groups from the plains of Vietnam. The presence of two groups of melons in Southeast Asia was also indicated by population structure and principal coordinate analysis. These results indicated a close genetic relationship between Cambodia and the neighboring countries, thus suggesting that Cambodian melons are not directly related to the establishment of Conomon and Makuwa. en-copyright= kn-copyright= en-aut-name=NazninPervin Mst en-aut-sei=Naznin en-aut-mei=Pervin Mst kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImohOdirichi Nnennaya en-aut-sei=Imoh en-aut-mei=Odirichi Nnennaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKatsunori en-aut-sei=Tanaka en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SreynechOuch en-aut-sei=Sreynech en-aut-mei=Ouch kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigitaGentaro en-aut-sei=Shigita en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SopheaYon en-aut-sei=Sophea en-aut-mei=Yon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SophanySakhan en-aut-sei=Sophany en-aut-mei=Sakhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakaraOuk en-aut-sei=Makara en-aut-mei=Ouk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomookaNorihiko en-aut-sei=Tomooka en-aut-mei=Norihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishidaHidetaka en-aut-sei=Nishida en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KatoKenji en-aut-sei=Kato en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=4 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=5 en-affil=Department of Life Science Systems, Technical University of Munich kn-affil= affil-num=6 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=7 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=8 en-affil=Plant Breeder, Retired Director of the Cambodian Agricultural Research and Development Institute kn-affil= affil-num=9 en-affil=Research Center of Genetic Resources, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Cambodia kn-keyword=Cambodia en-keyword=Conomon kn-keyword=Conomon en-keyword=Cucumis melo kn-keyword=Cucumis melo en-keyword=Genetic diversity kn-keyword=Genetic diversity en-keyword=Landraces kn-keyword=Landraces en-keyword=RAPD kn-keyword=RAPD en-keyword=SSR kn-keyword=SSR END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue=10 article-no= start-page=3848 end-page=3856 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Combination therapy with hydrogen peroxide and irradiation promotes an abscopal effect in mouse models en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hydrogen peroxide (H2O2) induces oxidative stress and cytotoxicity, and can be used for treating cancers in combination with radiotherapy. A product comprising H2O2 and sodium hyaluronate has been developed as a radiosensitizer. However, the effects of H2O2 on antitumor immunity remain unclear. To investigate the effects of H2O2, especially the abscopal effect when combined with radiotherapy (RT), we implanted murine tumor cells simultaneously in two locations in mouse models: the hind limb and back. H2O2 mixed with sodium hyaluronate was injected intratumorally, followed by irradiation only at the hind limb lesion. No treatment was administered to the back lesion. The H2O2/RT combination significantly reduced tumor growth at the noninjected/nonirradiated site in the back lesion, whereas H2O2 or RT individually did not reduce tumor growth. Flow cytometric analyses of the tumor-draining lymph nodes in the injected/irradiated areas showed that the number of dendritic cells increased significantly with maturation in the H2O2/RT combination group. In addition, analyses of tumor-infiltrating lymphocytes showed that the number of CD8+ (cluster of differentiation 8) T cells and the frequency of IFN-γ+ (interferon gamma) CD8+ T cells were higher in the noninjected/nonirradiated tumors in the H2O2/RT group compared to those in the other groups. PD-1 (programmed death receptor 1) blockade further increased the antitumor effect against noninjected/nonirradiated tumors in the H2O2/RT group. Intratumoral injection of H2O2 combined with RT therefore induces an abscopal effect by activating antitumor immunity, which can be further enhanced by PD-1 blockade. These findings promote the development of H2O2/RT therapy combined with cancer immunotherapies, even for advanced cancers. en-copyright= kn-copyright= en-aut-name=KemmotsuNaoya en-aut-sei=Kemmotsu en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuLi en-aut-sei=Zhu en-aut-mei=Li kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FangYue en-aut-sei=Fang en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Microbial and Biochemical Pharmacy, School of Pharmacy, China Medical University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=abscopal effect kn-keyword=abscopal effect en-keyword=dendritic cell kn-keyword=dendritic cell en-keyword=hydrogen peroxide kn-keyword=hydrogen peroxide en-keyword=radiosensitizer kn-keyword=radiosensitizer en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=tumor-draining lymph node kn-keyword=tumor-draining lymph node END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=4 article-no= start-page=553 end-page=560 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=At-risk internet addiction and related factors among senior high school teachers in Japan based on a Nationwide survey en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Internet addiction (IA) has been drawing attention to mental health. However, few reports have been found on the related factors of at-risk IA among regular workers by a nationwide survey. The study aimed to evaluate the characteristics of at-risk IA and identify related factors among senior high school teachers in Japan.
Methods:This survey was a cross-sectional survey of high schools across Japan in 2017. There were 3189 teachers (2088 males and 1098 female) who participated in this survey. The questionnaire asked about their devices, both the time and the activities of using their internet, and sociodemographic factors. IA was measured by the internet addiction test (IAT) by which 40-79 points were classified as at-risk IA, and more as IA. We compared the related factors of at-risk IA and non-IA using descriptive analysis and multivariable regression analysis.
Results: The rates of IA and at-risk IA were 0.09% (n = 3) and 6.91% (n = 220), respectively. At-risk IA was positively associated with activities on the internet for gaming, entertainment, net-surfing, and younger ages. In addition, the at-risk IA group had a longer time spent on the internet than the non-IA group.
Conclusions: Around 7% of high school teachers are at-risk IA in this survey, though they have regular work. Our results suggest that at-risk IA may be reinforced not only by the active internet use such as gaming, but also by purposeless behaviors, such as net-surfing. Managing time on the internet may support preventing at-risk IA among senior high school teachers. en-copyright= kn-copyright= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChowdhuryMohammad en-aut-sei=Chowdhury en-aut-mei=Mohammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChowdhuryTanvir Turin en-aut-sei=Chowdhury en-aut-mei=Tanvir Turin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsumuraHideki en-aut-sei=Tsumura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuchieRina en-aut-sei=Tsuchie en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=University of Calgary kn-affil= affil-num=3 en-affil=University of Calgary kn-affil= affil-num=4 en-affil=Tokushima University kn-affil= affil-num=5 en-affil=Shimane University kn-affil= affil-num=6 en-affil=Okayama University kn-affil= affil-num=7 en-affil=Okayama University kn-affil= affil-num=8 en-affil=Okayama University kn-affil= en-keyword=epidemiology of mental disorders kn-keyword=epidemiology of mental disorders en-keyword=internet addiction kn-keyword=internet addiction en-keyword=Nationwide survey kn-keyword=Nationwide survey en-keyword=preventive medicine kn-keyword=preventive medicine en-keyword=teachers kn-keyword=teachers END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=e39466 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagenous Colitis in a Patient With Gastric Cancer Who Underwent Chemotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Herein, we present a case of collagenous colitis in a patient who underwent chemotherapy for gastric cancer, comprising five cycles of S-1 plus oxaliplatin and trastuzumab, followed by five cycles of paclitaxel and ramucirumab and seven cycles of nivolumab. The subsequent initiation of trastuzumab deruxtecan chemotherapy led to the development of grade 3 diarrhea after the second cycle of treatment. Collagenous colitis was diagnosed via colonoscopy and biopsy. The patient's diarrhea improved following the cessation of lansoprazole. This case highlights the importance of considering collagenous colitis as a differential diagnosis, in addition to chemotherapy-induced colitis and immune-related adverse event (irAE) colitis, in patients with similar clinical presentations. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InooShoko en-aut-sei=Inoo en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=chemotherapy-induced diarrhea kn-keyword=chemotherapy-induced diarrhea en-keyword=immune-related adverse event colitis kn-keyword=immune-related adverse event colitis en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=collagenous colitis kn-keyword=collagenous colitis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=8386 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comprehensive hemocompatibility analysis on the application of diamond-like carbon to ePTFE artificial vascular prosthesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to obtain comprehensive data regarding the hemocompatibility of diamond-like carbon (DLC)-coated expanded polytetrafluoroethylene (ePTFE). DLC increased the hydrophilicity and smoothened the surface and fibrillar structure, respectively, of the ePTFE. DLC-coated ePTFE had more albumin and fibrinogen adsorption and less platelet adhesion than uncoated ePTFE. There were scarce red cell attachments in in vitro human and in vivo animal (rat and swine) whole blood contact tests in both DLC-coated and uncoated ePTFE. DLC-coated ePTFE had a similar but marginally thicker band movement than uncoated-ePTFE with SDS-PAGE after human whole blood contact test. In addition, survival studies of aortic graft replacement in rats (1.5 mm graft) and arteriovenous shunt in goats (4 mm graft) were performed to compare the patency and clot formation between DLC-coated and uncoated ePTFE grafts. Comparable patency was observed in both animal models. However, clots were observed in the luminal surface of the patent 1.5 mm DLC-coated ePTFE grafts, but not in that of uncoated ePTFE grafts. In conclusions, hemocompatibility of DLC-coated ePTFE was high and comparable to that of uncoated ePTFE. However, it failed to improve the hemocompatibility of 1.5 mm ePTFE graft probably because increased fibrinogen adsorption canceled the other beneficial effects of DLC. en-copyright= kn-copyright= en-aut-name=GoyamaTakashi en-aut-sei=Goyama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiYasuhiro en-aut-sei=Fujii en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraokaGenya en-aut-sei=Muraoka en-aut-mei=Genya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakataniTatsuyuki en-aut-sei=Nakatani en-aut-mei=Tatsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OusakaDaiki en-aut-sei=Ousaka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ImaiYuichi en-aut-sei=Imai en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuwadaNoriaki en-aut-sei=Kuwada en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujiTatsunori en-aut-sei=Tsuji en-aut-mei=Tatsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShukuTakayuki en-aut-sei=Shuku en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OozawaSusumu en-aut-sei=Oozawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Institute of Frontier Science and Technology, Okayama University of Science kn-affil= affil-num=5 en-affil=Department of Pharmacology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Institute of Frontier Science and Technology, Okayama University of Science kn-affil= affil-num=7 en-affil=Department of Cardiovascular Surgery, Kawasaki Medical Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Civil Engineering, Okayama University Graduate School of Environmental and Life Science kn-affil= affil-num=10 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Translational Research and Drug Development, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Division of Medical Safety Management, Safety Management Facility, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=11-12 article-no= start-page=5127 end-page=5137 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surface smoothing of additively manufactured Ti-6Al-4V alloy by combination of grit blasting and large-area electron beam irradiation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Additively manufactured (AMed) titanium products are typically produced by electron beam melting (EBM), since oxidation of titanium alloy surface can be suppressed in vacuum environment. The surface roughness of AMed titanium products becomes more than 200 ?m Rz, and the very rough surface would lead to reduction in fatigue strength. Therefore, a post surface finishing process is required. Abrasive blasting is one of the common surface smoothing processes of AMed metal products. Large surface roughness can be decreased, and compressive residual stress can be introduced to the surface. However, there is a limitation to reduction of surface roughness to several ?m Rz. On the other hand, it was recently found that AMed metal surface produced by powder bed fusion with laser beam could be smoothed by large-area electron beam (LEB) irradiation. However, it is difficult to smooth surface with large initial surface roughness, and a tensile residual stress may be generated on the surface. In this study, surface smoothing and change in residual stress of AMed titanium alloy (Ti-6Al-4 V) were proposed by combination of grit blasting and LEB irradiation. Surface roughness of AMed Ti-6Al-4 V alloy significantly decreases from 265 to about 2.0 ?m Rz by combination of grit blasting and LEB irradiation. Reduction rate of surface roughness by LEB irradiation linearly increases with decreasing mean width of blasted surface. Influence of the mean width on smoothing effect by LEB irradiation can be explained by thermo-fluid analysis. Moreover, tensile residual stress caused by LEB irradiation can be reduced when LEB is irradiated to blasted surface. en-copyright= kn-copyright= en-aut-name=ShinonagaTogo en-aut-sei=Shinonaga en-aut-mei=Togo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiHiroya en-aut-sei=Kobayashi en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaAkira en-aut-sei=Okada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujiToshiya en-aut-sei=Tsuji en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=SINTOKOGIO, LTD kn-affil= en-keyword=Additive manufacturing kn-keyword=Additive manufacturing en-keyword=Electron beam melting kn-keyword=Electron beam melting en-keyword=Titanium alloy kn-keyword=Titanium alloy en-keyword=Ti-6Al-4 V kn-keyword=Ti-6Al-4 V en-keyword=Blasting kn-keyword=Blasting en-keyword=Large-area electron beam kn-keyword=Large-area electron beam en-keyword=Surface smoothing kn-keyword=Surface smoothing en-keyword=Thermo-fluid analysis kn-keyword=Thermo-fluid analysis en-keyword=Residual stress kn-keyword=Residual stress END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=918273 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sea Surface Temperature and Salinity in Lombok Strait Reconstructed From Coral Sr/Ca and δ18O, 1962?2012 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Coral geochemical tracers have been used in studies of the paleoclimatology and paleoceanography of the tropics and subtropics. We measured Sr/Ca and oxygen isotope ratios (δ18O) in a coral sample collected from the southern part of Lombok Strait, a significant outlet of the Indonesian Throughflow (ITF) to the Indian Ocean, to reconstruct the historical record of sea surface temperature (SST) and seawater δ18O. Seawater δ18O can be used to approximate sea surface salinity (SSS) because it reflects the balance of evaporation and precipitation. The resulting time series reconstructed SST and SSS, covering the period 1962?2012, shows no clear trend of global warming, although the record includes a large cooling event (~4°C) during 1996?1997. Although neither SST nor SSS shows a systematic relationship with El Ni?o?Southern Oscillation and Indian Ocean Dipole (IOD), weak but significant correlations are found partly. In addition, the coral data show signals of major IOD and El Ni?o events in 1994 and 1997, respectively, although climatic trends recorded in the coral are not consistent with those found along the Java-Sumatra coast. To evaluate other influences on the ITF in Lombok Strait, we compared our coral record with coral records from sites in the Java Sea, the southern part of Makassar Strait, and Ombai Strait. During the northwest monsoon (December?January?February), variations in SST and SSS at Lombok Strait site are similar to those at the Java Sea and southern Makassar sites for the period 1962?1995, which suggests that low-salinity water from the Java Sea is carried at least to the southern part of Makassar Strait where it suppresses the ITF upstream from Lombok Strait. However, the SST and SSS records differ at the three sites during the southeast monsoon (June?July?August), indicating that surface conditions in Lombok Strait vary separately from those in the Java Sea. In the longer term, although global warming has been widely identified in the Indonesian Seas, the coral record shows no clear warming trend in the southern part of Lombok Strait, where fluctuations in the ITF may be modulating the distribution of heat in the surface waters of the western Pacific and eastern Indian Ocean. en-copyright= kn-copyright= en-aut-name=GendaAi en-aut-sei=Genda en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkeharaMinoru en-aut-sei=Ikehara en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiAtsushi en-aut-sei=Suzuki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArmanAli en-aut-sei=Arman en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueMayuri en-aut-sei=Inoue en-aut-mei=Mayuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Center for Advanced Marine Core Research, Kochi University kn-affil= affil-num=3 en-affil=Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Research and Technology Center for Application of Isotope and Radiation, National Research and Innovation Agency kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=coral kn-keyword=coral en-keyword=geochemical tracers kn-keyword=geochemical tracers en-keyword=Sr/Ca kn-keyword=Sr/Ca en-keyword=δ 18O kn-keyword=δ 18O en-keyword=sea surface temperature kn-keyword=sea surface temperature en-keyword=salinity kn-keyword=salinity en-keyword=Lombok Strait kn-keyword=Lombok Strait END start-ver=1.4 cd-journal=joma no-vol=189 cd-vols= no-issue=1 article-no= start-page=329 end-page=343 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photosystem I light-harvesting proteins regulate photosynthetic electron transfer and hydrogen production en-subtitle= kn-subtitle= en-abstract= kn-abstract=Linear electron flow (LEF) and cyclic electron flow (CEF) compete for light-driven electrons transferred from the acceptor side of photosystem I (PSI). Under anoxic conditions, such highly reducing electrons also could be used for hydrogen (H2) production via electron transfer between ferredoxin and hydrogenase in the green alga Chlamydomonas reinhardtii. Partitioning between LEF and CEF is regulated through PROTON-GRADIENT REGULATION5 (PGR5). There is evidence that partitioning of electrons also could be mediated via PSI remodeling processes. This plasticity is linked to the dynamics of PSI-associated light-harvesting proteins (LHCAs) LHCA2 and LHCA9. These two unique light-harvesting proteins are distinct from all other LHCAs because they are loosely bound at the PSAL pole. Here, we investigated photosynthetic electron transfer and H2 production in single, double, and triple mutants deficient in PGR5, LHCA2, and LHCA9. Our data indicate that lhca2 and lhca9 mutants are efficient in photosynthetic electron transfer, that LHCA2 impacts the pgr5 phenotype, and that pgr5/lhca2 is a potent H2 photo-producer. In addition, pgr5/lhca2 and pgr5/lhca9 mutants displayed substantially different H2 photo-production kinetics. This indicates that the absence of LHCA2 or LHCA9 impacts H2 photo-production independently, despite both being attached at the PSAL pole, pointing to distinct regulatory capacities. en-copyright= kn-copyright= en-aut-name=HoThi Thu Hoai en-aut-sei=Ho en-aut-mei=Thi Thu Hoai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SchwierChris en-aut-sei=Schwier en-aut-mei=Chris kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ElmanTamar en-aut-sei=Elman en-aut-mei=Tamar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FleuterVera en-aut-sei=Fleuter en-aut-mei=Vera kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZinziusKaren en-aut-sei=Zinzius en-aut-mei=Karen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ScholzMartin en-aut-sei=Scholz en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YacobyIftach en-aut-sei=Yacoby en-aut-mei=Iftach kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BuchertFelix en-aut-sei=Buchert en-aut-mei=Felix kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HipplerMichael en-aut-sei=Hippler en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=2 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=3 en-affil=School of Plant Sciences and Food Security, The George S.

When applying the idea to improve the work-life balance of physicians in the medical field, we must consider the increased stress owing to their long continuous working hours. Estimating the stress of physicians in their daily lives by the questionnaires is insufficient, because of the difficulty of accurate their activity recalling. By using bio-metric information such as heart rate, physical activity, and sleeping information, it was expected that the daily stress state of physicians with high accuracy. In this paper, we propose a method for estimating physician stress by analyzing bio-metric information acquired by wearing a wearable sensor device. The proposed method estimates the state of stress during daily activities by acquiring data on heart rate variability (HRV) during wakefulness as well as sleep depth during rapid eye movement (REM) and non-REM sleep. Up to seven physicians wore the wearable sensor device for the maximum of eight weeks and the sleep depth and low-/high-frequency (LF/HF) components of HRV were obtained. Our observation showed that physicians' root mean square of successive differences (rMSSDs) were constantly high in their healthy state. Therefore, the decreasing of this index can be used as an indicator of fatigue and stress. In addition, by combining LF/HF components to the rMSSDs, we may estimate the stress state of physicians and find personal stressors. en-copyright= kn-copyright= en-aut-name=ImuraIssei en-aut-sei=Imura en-aut-mei=Issei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotohYusuke en-aut-sei=Gotoh en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaiKoji en-aut-sei=Sakai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OharaYu en-aut-sei=Ohara en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TazoeJun en-aut-sei=Tazoe en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiuraHiroshi en-aut-sei=Miura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirotaTatsuya en-aut-sei=Hirota en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchiyamaAkira en-aut-sei=Uchiyama en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NomuraYoshinari en-aut-sei=Nomura en-aut-mei=Yoshinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=5 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=6 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=7 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=8 en-affil=Graduate School of Information Science and Technology, Osaka University kn-affil= affil-num=9 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= en-keyword=heart rate variability kn-keyword=heart rate variability en-keyword=LF/HF kn-keyword=LF/HF en-keyword=Society 5.0 kn-keyword=Society 5.0 en-keyword=stress kn-keyword=stress en-keyword=wearable sensor devices kn-keyword=wearable sensor devices en-keyword=working style kn-keyword=working style END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=7 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of and Immune Responses to SARS-CoV-2 mRNA Vaccines and Their Mechanisms en-subtitle= kn-subtitle= en-abstract= kn-abstract=Following the online publication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome in January 2020, two lipid nanoparticle-encapsulated mRNA vaccines, BNT162b2 and mRNA-1273, were rapidly developed and are now being used worldwide to prevent coronavirus disease 2019 (COVID-19). The mRNA of both vaccines encodes the full-length spike protein of SARS-CoV-2, which binds to the host cell receptor angiotensin-converting enzyme 2 and is believed to mediate virus entry into cells. After intramuscular injection of the vaccine, the spike protein is produced in the cells. Both humoral and cellular immune responses to the spike protein are elicited for protection against COVID-19. The efficacy of the two mRNA vaccines against COVID-19 with wild-type SARS-CoV-2 is more than 90% and is slightly decreased with the Delta variant, which is currently the predominant variant in many countries. In this review, the effectiveness of and immune responses to COVID-19 mRNA vaccines and their mechanisms are summarized and discussed. Potential waning immunity and an additional dose of COVID-19 mRNA vaccines are also discussed. en-copyright= kn-copyright= en-aut-name=GohdaEiichi en-aut-sei=Gohda en-aut-mei=Eiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Okayama University kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 en-keyword=mRNA vaccine kn-keyword=mRNA vaccine en-keyword=immune response kn-keyword=immune response END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=2 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of calculation processes of apparent diffusion coefficient subtraction method (ASM) imaging en-subtitle= kn-subtitle= en-abstract= kn-abstract=A number of restricted diffusion (RD) imaging techniques, such as diffusion kurtosis (DK) imaging and Q space imaging, have been developed and proven to be useful for the diagnosis of diseases, including cerebral gliomas and cerebrovascular infarction. In particular, apparent diffusion coefficient (ADC) subtraction method (ASM) imaging has become available recently as a novel RD imaging technique. ASM is based on the difference between the ADC values in an image pair of two ADC maps, ADC basic (ADCb) and ADC modify (ADCm), which are created from diffusion-weighted images taken using short and long effective diffusion times, respectively. The present study aimed to assess the potential of different types of ASM imaging by comparing them with DK imaging which is the gold-standard RD imaging technique. In the present basic study using both polyethylene glycol phantom and cell-containing bio-phantom, three different types of ASM images were created using different calculation processes. ASM/A is an image calculated by dividing the absolute difference between ADCb and ADCm by ADCb several times. By contrast, ASM/S is an image created by dividing the absolute difference between ADCb and ADCm by the standard deviation of ADCb several times. As for positive ASM/A image (PASM/A), the positive image, which was resultant after subtracting ADCb from ADCm, was divided by ADCb several times. A comparison was made between the types of ASM and DK images. The results showed the same tendency between ASM/A in addition to both ASM/S and PASM/A. By increasing the number of divisions by ADCb from three to five times, ASM/A images transformed from DK-mimicking to more RD-sensitive images compared with DK images.

are developing the user-PC computing (UPC) system based on the master-worker model as a scalable, low-cost, and high-performance computing platform. To run various application programs on personal computers (PCs) with different environments for workers, it adopts Docker technology to bundle every necessary software as one image file. Unfortunately, the Docker file/image are manually generated through multiple steps by a user, which can be the bottleneck. In this paper, we present a web-based Docker image assistant generation (DIAG) tool in the UPC system to assist or reduce these process steps. It adopts Angular JavaScript for offering user interfaces, PHP Laravel for handling logic using RestAPI, MySQL database for storing data, and Shell scripting for speedily running the whole program. In addition, the worker-side code modification function is implemented so that a user can modify the source code of the running job and update the Docker image at a worker to speed up them. For evaluations, we collected 30 Docker files and 10 OpenFOAM jobs through reverse processing from Docker images in Github and generated the Docker images using the tool. Moreover, we modified source codes for network simulations and generated the Docker images in a worker five times. The results confirmed the validity of the proposal. en-copyright= kn-copyright= en-aut-name=AungLynn Htet en-aut-sei=Aung en-aut-mei=Lynn Htet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhouXudong en-aut-sei=Zhou en-aut-mei=Xudong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=XiangXu en-aut-sei=Xiang en-aut-mei=Xu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaoWen-Chung en-aut-sei=Kao en-aut-mei=Wen-Chung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=Docker kn-keyword=Docker en-keyword=automatic generation kn-keyword=automatic generation en-keyword=Angular kn-keyword=Angular en-keyword=Laravel kn-keyword=Laravel en-keyword=MySQL kn-keyword=MySQL en-keyword=Shell scripting kn-keyword=Shell scripting en-keyword=image update kn-keyword=image update en-keyword=UPC system kn-keyword=UPC system END start-ver=1.4 cd-journal=joma no-vol=299 cd-vols= no-issue=4 article-no= start-page=104587 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ATP and its metabolite adenosine cooperatively upregulate the antigen-presenting molecules on dendritic cells leading to IFN-gamma production by T cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dendritic cells (DCs) present foreign antigens to T cells via the major histocompatibility complex (MHC), thereby inducing acquired immune responses. ATP accumulates at sites of inflammation or in tumor tissues, which triggers local inflammatory responses. However, it remains to be clarified how ATP modulates the functions of DCs. In this study, we investigated the effects of extracellular ATP on mouse bone marrow- derived dendritic cells (BMDCs) as well as the potential for subsequent T cell activation. We found that high concentrations of ATP (1 mM) upregulated the cell surface expression levels of MHC-I, MHC-II, and co-stimulatory molecules CD80 and CD86 but not those of co-inhibitory molecules PD-L1 and PD-L2 in BMDCs. Increased surface expression of MHC-I, MHC-II, CD80, and CD86 was inhibited by a pan-P2 receptor antagonist. In addition, the upregulation of MHC-I and MHC-II expression was inhibited by an adenosine P1 receptor antagonist and by inhibitors of CD39 and CD73, which metabolize ATP to adenosine. These results suggest that adenosine is required for the ATP-induced upregulation of MHC-I and MHC-II. In the mixed leukocyte reaction assay, ATP-stimulated BMDCs activated CD4 and CD8T cells and induced interferon-gamma (IFN-gamma) production by these T cells. Collectively, these results suggest that high concentrations of extracellular ATP upregulate the expression of antigenpresenting and co-stimulatory molecules but not that of coinhibitory molecules in BMDCs. Cooperative stimulation of ATP and its metabolite adenosine was required for the upregulation of MHC-I and MHC-II. These ATP-stimulated BMDCs induced the activation of IFN-gamma-producing T cells upon antigen presentation. en-copyright= kn-copyright= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiHiroka en-aut-sei=Onishi en-aut-mei=Hiroka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkadaYuki en-aut-sei=Ikada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasakiKento en-aut-sei=Masaki en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pharmacology, Division of Pathological Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=6 article-no= start-page=e7595 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230620 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ANCA-associated vasculitis with scleritis, corneal melt, and perforation rescued by rituximab: Case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Key Clinical Message: Patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, specifically with myeloperoxidase (MPO)-ANCA, would have a risk for developing corneal melt and perforation abruptly in a short period.

Abstract: An 80-year old man who had been diagnosed 5.5?years previously as ANCA-associated vasculitis by temporal artery biopsy developed corneal melt and perforation with scleritis in both eyes. He underwent successful cataract surgery and retained ambulatory vision with the aid of intravenous rituximab. Two additional patients with similar manifestations were found in the literature. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Hiramatsu‐AsanoSumie en-aut-sei=Hiramatsu‐Asano en-aut-mei=Sumie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SawachikaHiroshi en-aut-sei=Sawachika en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishimuraHirotake en-aut-sei=Nishimura en-aut-mei=Hirotake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Rheumatology, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Rheumatology, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= en-keyword=ANCA-associated vasculitis kn-keyword=ANCA-associated vasculitis en-keyword=corneal melt and perforation kn-keyword=corneal melt and perforation en-keyword=rituximab kn-keyword=rituximab en-keyword=scleritis kn-keyword=scleritis en-keyword=temporal artery biopsy kn-keyword=temporal artery biopsy END start-ver=1.4 cd-journal=joma no-vol=E106.B cd-vols= no-issue=2 article-no= start-page=193 end-page=202 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multi-Input Physical Layer Network Coding in Two-Dimensional Wireless Multihop Networks en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes multi-input physical layer network coding (multi-input PLNC) for high speed wireless communication in two-dimensional wireless multihop networks. In the proposed PLNC, all the terminals send their packets simultaneously for the neighboring relays to maximize the network throughput in the first slot, and all the relays also do the same to the neighboring terminals in the second slot. Those simultaneous signal transmissions cause multiple signals to be received at the relays and the terminals. Signal reception in the multi-input PLNC uses multichannel filtering to mitigate the difficulties caused by the multiple signal reception, which enables the two-input PLNC to be applied. In addition, a non-linear precoding is proposed to reduce the computational complexity of the signal detection at the relays and the terminals. The proposed multi-input PLNC makes all the terminals exchange their packets with the neighboring terminals in only two time slots. The performance of the proposed multi-input PLNC is confirmed by computer simulation. The proposed multi-input physical layer network coding achieves much higher network throughput than conventional techniques in a two-dimensional multihop wireless network with 7 terminals. The proposed multi-input physical layer network coding attains superior transmission performance in wireless hexagonal multihop networks, as long as more than 6 antennas are placed on the terminals and the relays. en-copyright= kn-copyright= en-aut-name=TSUGITAHideaki en-aut-sei=TSUGITA en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DENNOSatoshi en-aut-sei=DENNO en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HOUYafei en-aut-sei=HOU en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=physical layer network coding kn-keyword=physical layer network coding en-keyword=precoding kn-keyword=precoding en-keyword=multihop network kn-keyword=multihop network en-keyword=singular value decomposition kn-keyword=singular value decomposition END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=8 article-no= start-page=1997 end-page=2005 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Study on joint characteristics in laser butt welding of AMed and wrought Ti6Al4V plates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Titanium alloy Ti6Al4V has been widely applied to medical, automotive, and aerospace industries due to its excellent properties such as high strength and excellent corrosion resistance. On the other hand, additive manufacturing (AM) technology can give the freedom of design of the products. In order to spread the AMed products, the joining of AMed and wrought products are required, and it is important to understand the joint characteristics. In this study, butt welding of Ti6Al4V plate was conducted by fiber laser in argon shielding, and the joint characteristics of laser weld wrought/wrought, AMed/AMed, and AMed/wrought Ti6Al4V plates were experimentally investigated. The AMed plate has higher tensile strength than wrought plate but the elongation of AMed plate is smaller, since AMed plate has α’ martensite due to rapid cooling during laser irradiation in AM process. Then, the laser weld joint of AMed/AMed plates has higher tensile strength, but smaller elongation than that of wrought/wrought plates. The weld joint of AMed/wrought plates shows good welding state, since small heat input leads to formation of small weld bead with higher hardness between wrought and AMed plates. en-copyright= kn-copyright= en-aut-name=OkamotoYasuhiro en-aut-sei=Okamoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinonagaTogo en-aut-sei=Shinonaga en-aut-mei=Togo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakemotoYoshito en-aut-sei=Takemoto en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaAkira en-aut-sei=Okada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OchiAkihiro en-aut-sei=Ochi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishimotoRyuya en-aut-sei=Kishimoto en-aut-mei=Ryuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PityanaSisa en-aut-sei=Pityana en-aut-mei=Sisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ArthurNana en-aut-sei=Arthur en-aut-mei=Nana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OmoniyiPeter en-aut-sei=Omoniyi en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MahamoodRasheedat en-aut-sei=Mahamood en-aut-mei=Rasheedat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MainaMartin en-aut-sei=Maina en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkinlabiEsther en-aut-sei=Akinlabi en-aut-mei=Esther kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= affil-num=5 en-affil=Okayama University kn-affil= affil-num=6 en-affil=Okayama University kn-affil= affil-num=7 en-affil=National Laser Centre, CSIR kn-affil= affil-num=8 en-affil=National Laser Centre, CSIR kn-affil= affil-num=9 en-affil=University of Johannesburg kn-affil= affil-num=10 en-affil=University of Johannesburg kn-affil= affil-num=11 en-affil=Jomo Kenyatta University of Agriculture and Technology kn-affil= affil-num=12 en-affil=University of Johannesburg kn-affil= en-keyword=Ti6Al4V kn-keyword=Ti6Al4V en-keyword=Joint characteristics kn-keyword=Joint characteristics en-keyword=Laser welding kn-keyword=Laser welding en-keyword=Butt welding kn-keyword=Butt welding en-keyword=Additive manufacturing kn-keyword=Additive manufacturing END start-ver=1.4 cd-journal=joma no-vol=E106.B cd-vols= no-issue=2 article-no= start-page=184 end-page=192 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Superposition Signal Input Decoding for Lattice Reduction-Aided MIMO Receivers en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes a novel approach to low complexity soft input decoding for lattice reduction-aided MIMO receivers. The proposed approach feeds a soft input decoder with soft signals made from hard decision signals generated by using a lattice reduction-aided linear detector. The soft signal is a weighted-sum of some candidate vectors that are near by the hard decision signal coming out from the lattice reduction-aided linear detector. This paper proposes a technique to adjust the weight adapt to the channel for the higher transmission performance. Furthermore, we propose to introduce a coefficient that is used for the weights in order to enhance the transmission performance. The transmission performance is evaluated in a 4×4 MIMO channel. When a linear MMSE filter or a serial interference canceller is used as the linear detector, the proposed technique achieves about 1.0dB better transmission performance at the BER of 10-5 than the decoder fed with the hard decision signals. In addition, the low computational complexity of the proposed technique is quantitatively evaluated. en-copyright= kn-copyright= en-aut-name=DENNOSatoshi en-aut-sei=DENNO en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KASHIHARAKoki en-aut-sei=KASHIHARA en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HOUYafei en-aut-sei=HOU en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=soft decision kn-keyword=soft decision en-keyword=weighted sum kn-keyword=weighted sum en-keyword=lattice reduction kn-keyword=lattice reduction en-keyword=linear detectors kn-keyword=linear detectors en-keyword=low computational complexity kn-keyword=low computational complexity END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue= article-no= start-page=52 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comprehensive study of metabolic changes induced by a ketogenic diet therapy using GC/MS- and LC/MS-based metabolomics en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The ketogenic diet (KD), a high-fat and low-carbohydrate diet, is effective for a subset of patients with drug-resistant epilepsy, although the mechanisms of the KD have not been fully elucidated. The aims of this observational study were to investigate comprehensive short-term metabolic changes induced by the KD and to explore candidate metabolites or pathways for potential new therapeutic targets.
Methods: Subjects included patients with intractable epilepsy who had undergone the KD therapy (the medium-chain triglyceride [MCT] KD or the modified Atkins diet using MCT oil). Plasma and urine samples were obtained before and at 2?4 weeks after initiation of the KD. Targeted metabolome analyses of these samples were performed using gas chromatography-tandem mass spectrometry (GC/MS/MS) and liquid chromatography-tandem mass spectrometry (LC/MS/MS).
Results: Samples from 10 and 11 patients were analysed using GC/MS/MS and LC/MS/MS, respectively. The KD increased ketone bodies, various fatty acids, lipids, and their conjugates. In addition, levels of metabolites located upstream of acetyl-CoA and propionyl-CoA, including catabolites of branched-chain amino acids and structural analogues of γ-aminobutyric acid and lactic acid, were elevated.
Conclusions: The metabolites that were significantly changed after the initiation of the KD and related metabolites may be candidates for further studies for neuronal actions to develop new anti-seizure medications. en-copyright= kn-copyright= en-aut-name=AkiyamaMari en-aut-sei=Akiyama en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaigusaDaisuke en-aut-sei=Saigusa en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HishinumaEiji en-aut-sei=Hishinuma en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsukawaNaomi en-aut-sei=Matsukawa en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibataTakashi en-aut-sei=Shibata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsuchiyaHiroki en-aut-sei=Tsuchiya en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiYuji en-aut-sei=Fujii en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MogamiYukiko en-aut-sei=Mogami en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TokorodaniChiho en-aut-sei=Tokorodani en-aut-mei=Chiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KuwaharaKozue en-aut-sei=Kuwahara en-aut-mei=Kozue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=Numata-UematsuYurika en-aut-sei=Numata-Uematsu en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=InoueKenji en-aut-sei=Inoue en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KobayashiKatsuhiro en-aut-sei=Kobayashi en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Child Neurology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Paediatrics (Child Neurology), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Tohoku Medical Megabank Organization, Tohoku University kn-affil= affil-num=4 en-affil=Tohoku Medical Megabank Organization, Tohoku University kn-affil= affil-num=5 en-affil=Tohoku Medical Megabank Organization, Tohoku University kn-affil= affil-num=6 en-affil=Department of Child Neurology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Child Neurology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Neurology, Shiga Medical Centre for Children kn-affil= affil-num=9 en-affil=Department of Paediatrics, Hiroshima City Funairi Citizens Hospital kn-affil= affil-num=10 en-affil=Department of Paediatric Neurology, Osaka Women's and Children's Hospital kn-affil= affil-num=11 en-affil=Department of Paediatrics, Kochi Health Sciences Centre kn-affil= affil-num=12 en-affil=Department of Paediatrics, Ehime Prefectural Central Hospital, kn-affil= affil-num=13 en-affil=Department of Paediatrics, Tohoku University School of Medicine kn-affil= affil-num=14 en-affil=Department of Neurology, Shiga Medical Centre for Children kn-affil= affil-num=15 en-affil=Department of Paediatrics (Child Neurology), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Amino acids kn-keyword=Amino acids en-keyword=Biomarkers kn-keyword=Biomarkers en-keyword=Intractable epilepsy kn-keyword=Intractable epilepsy en-keyword=Ketone bodies kn-keyword=Ketone bodies en-keyword=Organic acids kn-keyword=Organic acids END start-ver=1.4 cd-journal=joma no-vol=2023 cd-vols= no-issue=6 article-no= start-page=063H01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Angular correlation of the two gamma rays produced in the thermal neutron capture on gadolinium-155 and gadolinium-157 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The ANNRI-Gd collaboration studied in detail the single gamma-ray spectrum produced from the thermal neutron capture on Gd-155 and Gd-157 in our previous publications. Gadolinium targets were exposed to a neutron beam provided by the Japan Spallation Neutron Source (JSNS) in J-PARC, Japan. In the present analysis, one new additional coaxial germanium crystal was used in combination with the 14 germanium crystals in the cluster detectors to study the angular correlation of the two gamma rays emitted in the same neutron capture. We present for the first time angular correlation functions for two gamma rays produced during the electromagnetic cascade transitions in the (n, gamma) reactions on Gd-155 and Gd-157. As expected, we observe mild angular correlations for the strong, but rare transitions from the resonance state to the two energy levels of known spin-parities. Contrariwise, we observe negligibly small angular correlations for arbitrary pairs of two gamma rays produced in the majority of cascade transitions from the resonance state to the dense continuum states. en-copyright= kn-copyright= en-aut-name=GouxPierre en-aut-sei=Goux en-aut-mei=Pierre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GlessgenFranz en-aut-sei=Glessgen en-aut-mei=Franz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GazzolaEnrico en-aut-sei=Gazzola en-aut-mei=Enrico kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ReenMandeep Singh en-aut-sei=Reen en-aut-mei=Mandeep Singh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FocillonWilliam en-aut-sei=Focillon en-aut-mei=William kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GoninMichel en-aut-sei=Gonin en-aut-mei=Michel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaTomoyuki en-aut-sei=Tanaka en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HagiwaraKaito en-aut-sei=Hagiwara en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AliAjmi en-aut-sei=Ali en-aut-mei=Ajmi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SudoTakashi en-aut-sei=Sudo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakudaMakoto en-aut-sei=Sakuda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=CollazuolGianmaria en-aut-sei=Collazuol en-aut-mei=Gianmaria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KimuraAtsushi en-aut-sei=Kimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NakamuraShoji en-aut-sei=Nakamura en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=IwamotoNobuyuki en-aut-sei=Iwamoto en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=WurmMichael en-aut-sei=Wurm en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= affil-num=5 en-affil=D?partement de Physique, ?cole Polytechnique, IN2P3/CNRS kn-affil= affil-num=6 en-affil=D?partement de Physique, ?cole Polytechnique, IN2P3/CNRS kn-affil= affil-num=7 en-affil=Department of Physics, Okayama University kn-affil= affil-num=8 en-affil=Department of Physics, Okayama University kn-affil= affil-num=9 en-affil=Department of Physics, Okayama University kn-affil= affil-num=10 en-affil=Department of Physics, Okayama University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= affil-num=12 en-affil=Department of Physics, Okayama University kn-affil= affil-num=13 en-affil=INFN Sezione di Padova and Universit? di Padova, Dipartimento di Fisica kn-affil= affil-num=14 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=15 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=16 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=17 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=18 en-affil=Institut f?r Physik, Johannes Gutenberg-Universit?t Mainz kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=263 end-page=272 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early Fluid Balance Is Associated with 90-Day Mortality in Patients Receiving Continuous Renal Replacement Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Continuous renal replacement therapy (CRRT) is widely used to control fluid balance, but the optimal fluid balance to improve the prognosis of patients remains debated. Appropriate fluid management may depend on hemodynamic status. We investigated the association between 90-day mortality and fluid balance/mean arterial pressure (MAP) in patients receiving CRRT. This single-center retrospective study was conducted between May 2018 and March 2021. Based on the cumulative fluid balance at 72 h after initiation of CRRT, the cases were divided into negative (< 0 mL) and positive (> 0 mL) fluid balance groups. Ninety-day mortality was higher in the positive fluid balance group (p=0.009). At 4 h before and after CRRT initiation, the mean MAP was lower in the positive fluid balance group (p<0.05). After multivariate cox adjustment, 72-h positive fluid balance was independently associated with 90-day mortality (p=0.004). In addition, the cumulative fluid balance was associated with 90-day mortality (p<0.05) in cases without shock, high APACHE II score, sepsis, dialysis dependence, or vasopressor use. A 72-h positive fluid balance was associated with 90-day mortality in patients receiving CRRT. en-copyright= kn-copyright= en-aut-name=GuoYusheng en-aut-sei=Guo en-aut-mei=Yusheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakaJunko en-aut-sei=Kosaka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=fluid management kn-keyword=fluid management en-keyword=continuous renal replacement therapy kn-keyword=continuous renal replacement therapy en-keyword=mortality kn-keyword=mortality en-keyword=mean arterial pressure kn-keyword=mean arterial pressure en-keyword=daily cumulative fluid balance kn-keyword=daily cumulative fluid balance END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=3 article-no= start-page=e0283701 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of illness representational patterns and examining differences of self-care behavior in the patterns in chronic kidney disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Self-care behavior is considered important for preventing the progression of chronic kidney disease (CKD). Although lifestyle interventions are popular, they have not been sufficiently effective. According to studies on other chronic diseases, illness representation has been found to formulate a pattern, and self-care behavior could differ depending on the pattern, which suggests difference in self-care behavior based on illness representation. This study examined what kind of illness representational patterns exist among CKD patients and whether there is a difference in self-care behavior depending on the pattern. A survey was conducted from the beginning of June to the end of October 2019 on 274 CKD patients who were either outpatients or hospitalized at general hospitals in Western Japan. The Illness Perception Questionnaire-Revised was used to assess illness representation and the Japanese Chronic Kidney Disease Self-Care scale was used to assess self-care behavior. Two-stage cluster analysis was used to identify clusters. Cluster features were examined using analysis of variance and Tukey HSD tests. Differences in self-care behavior scores among identified clusters were investigated. Two hundred and forty-four questionnaires were received, and 212 were analyzed. Participants were aged 64.9 +/- 12.9, and the estimated glomerular filtration rate was 33.7 +/- 15.8. Three clusters were identified: Cluster 1 represented the difficulty of making sense of the changed condition caused by the disease and easily falling into misunderstanding; Cluster 2 represented patients with disease conditions that impacted their daily life and emotional responses; Cluster 3 represented the controllability and understandability of the disease. Total self-care behavior scores indicated a significant difference between Cluster 1 (52.1 +/- 9.7) and Cluster 3 (57.7 +/- 8.2). In conclusion, we showed that three representational patterns exist among CKD patients. In addition, a difference was found in self-care behavior depending on the illness representational pattern, suggesting the need to focus on illness representation. en-copyright= kn-copyright= en-aut-name=KajiwaraYuki en-aut-sei=Kajiwara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=1105824 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Auditory affective content facilitates time-to-contact estimation of visual affective targets en-subtitle= kn-subtitle= en-abstract= kn-abstract=Reacting to a moving object requires an ability to estimate when a moving object reaches its destination, also referred to as the time-to-contact (TTC) estimation. Although the TTC estimation of threatening visually moving objects is known to be underestimated, the effect of the affective content of auditory information on visual TTC estimation remains unclear. We manipulated the velocity and presentation time to investigate the TTC of a threat or non-threat target with the addition of auditory information. In the task, a visual or an audiovisual target moved from right to left and disappeared behind an occluder. Participants' task was to estimate the TTC of the target, they needed to press a button when they thought that the target contacted a destination behind the occluder. Behaviorally, the additional auditory affective content facilitated TTC estimation; velocity was a more critical factor than presentation time in determining the audiovisual threat facilitation effect. Overall, the results indicate that exposure to auditory affective content can influence TTC estimation and that the effect of velocity on TTC estimation will provide more information than presentation time. en-copyright= kn-copyright= en-aut-name=LuFeifei en-aut-sei=Lu en-aut-mei=Feifei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiYou en-aut-sei=Li en-aut-mei=You kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangAijun en-aut-sei=Wang en-aut-mei=Aijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhangMing en-aut-sei=Zhang en-aut-mei=Ming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Psychology, Research Center for Psychology and Behavioral Sciences, Soochow University kn-affil= affil-num=2 en-affil=College of Chinese Language and Culture, Jinan University kn-affil= affil-num=3 en-affil=Applied Brain Science Lab, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Psychology, Research Center for Psychology and Behavioral Sciences, Soochow University kn-affil= affil-num=5 en-affil=Cognitive Neuroscience Laboratory, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=time-to-contact (TTC) estimation kn-keyword=time-to-contact (TTC) estimation en-keyword=threat kn-keyword=threat en-keyword=audiovisual integration kn-keyword=audiovisual integration en-keyword=velocity kn-keyword=velocity en-keyword=presentation time kn-keyword=presentation time END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=9 article-no= start-page=1495 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Antibacterial Efficacy of Cetylpyridinium Chloride-Montmorillonite Containing PMMA Resin Cement en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite being able to adhesively restore teeth, adhesives and cement do not possess any anticariogenic protection potential, by which caries recurrence may still occur and reduce the clinical lifetime of adhesive restorations. Several antibacterial agents have been incorporated into dental adhesives and cement to render them anticariogenic. Due to an additional therapeutic effect, such materials are classified as 'dental combination products' with more strict market regulations. We incorporated cetylpyridinium chloride (CPC), often used for oral hygiene applications, into montmorillonite (CPC-Mont), the latter to serve as a carrier for controlled CPC release. CPC-Mont incorporated into tissue conditioner has been approved by the Pharmaceuticals and Medical Devices Agency (PmontMDA) in Japan. To produce a clinically effective dental cement with the antibacterial potential to prevent secondary caries, we incorporated CPC-Mont into PMMA resin cement. We measured the flexural strength, shear bond strength onto dentin, CPC release, and the biofilm-inhibition potential of the experimental CPC-Mont-containing PMMA cement. An 8 and 10 wt% CPC-Mont concentration revealed the antibacterial potential without reducing the mechanical properties of the PMMA cement. en-copyright= kn-copyright= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakitaYoji en-aut-sei=Makita en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaYasuhiro en-aut-sei=Yoshida en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Van MeerbeekBart en-aut-sei=Van Meerbeek en-aut-mei=Bart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Pathology & Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Advanced Research Center for Oral and Craniofacial Science, Okayama University Dental School kn-affil= affil-num=3 en-affil=National Institute of Advanced Industrial Science and Technology (AIST), Health and Medical Research Institute kn-affil= affil-num=4 en-affil=Department of Biomaterials and Bioengineering, Faculty of Dental Medicine, Hokkaido University kn-affil= affil-num=5 en-affil=Department of Oral Health Sciences, BIOMAT & UZ Leuven (University Hospitals Leuven), Dentistry, KU Leuven (University of Leuven) kn-affil= en-keyword=biofilm kn-keyword=biofilm en-keyword=cetylpyridinium chloride kn-keyword=cetylpyridinium chloride en-keyword=montmorillonite kn-keyword=montmorillonite en-keyword=PMMA resin cement kn-keyword=PMMA resin cement en-keyword=antibacterial agents kn-keyword=antibacterial agents en-keyword=dentin kn-keyword=dentin en-keyword=bond strength kn-keyword=bond strength END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=4 article-no= start-page=635 end-page=643 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230517 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of low-dose/high-dose-rate X-irradiation on oxidative stress in organs following forced swim test and its combined effects on alcohol-induced liver damage in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=The liver's susceptibility to oxidative stress after a combination of forced swim test (FST) and low-dose-rate gamma-irradiation has been observed. Therefore, this study aims to clarify the effects of low-dose (0.1 and 0.5 Gy)/high-dose-rate (1.2 Gy/min) irradiation on combined oxidative stressors-liver damage associated with FST and alcohol administration. In addition, the effects of similar irradiation on FST-induced immobility, which induces psychomotor retardation, and antioxidative effects on the brain, lungs, liver and kidneys were investigated, and the results were compared with those of a similar previous study that utilized low-dose-rate irradiation. Low-dose/high-dose-rate (especially 0.5 Gy) irradiation temporarily worsened liver antioxidant function and hepatic function with FST- and alcohol administration-related oxidative damage; however, the damages improved soon after. In addition, the increase in total glutathione content in the liver contributed to the early improvement of hepatic functions. However, pre-irradiation did not suppress immobility during the FST. The results also suggested that the effects of low-dose/high-dose-rate irradiation on the antioxidant functions of each organ after the FST were different from those of low-dose/low-dose-rate irradiation. Overall, this study provides further insights into the effects of low-dose irradiation on exposure to a combination of different oxidative stressors. It will also contribute to the elucidation of dose rate effects on oxidative stress in the low-dose irradiation range. en-copyright= kn-copyright= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimotoYuki en-aut-sei=Fujimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MurakamiKaito en-aut-sei=Murakami en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YukimineRyohei en-aut-sei=Yukimine en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=low-dose/high-dose-rate irradiation kn-keyword=low-dose/high-dose-rate irradiation en-keyword=forced swim test kn-keyword=forced swim test en-keyword=alcohol kn-keyword=alcohol en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=antioxidants kn-keyword=antioxidants END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=4 article-no= start-page=2581 end-page=2593 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220818 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collaborative bargaining solution in tandem supply chain through cooperative game theoretical approach en-subtitle= kn-subtitle= en-abstract= kn-abstract=There are many studies about negotiation procedures for contract problems in supply chains. Several recent papers have considered a new negotiation procedure for a repurchase contract problem in a supply chain consisting of a manufacturer and a retailer. There, usually, are some wholesalers between a manufacturer and a retailer. Therefore, a supply chain including some wholesalers in addition to a manufacturer and a retailer should be considered. In this study, we call the supply chain in which three or more members are arranged in series the tandem supply chain. We, firstly, address a negotiation problem for a contract about wholesale and repurchase prices in the tandem supply chain in which three members, that is, a manufacturer, a wholesaler and a retailer are arranged in series. The whole contract in the tandem supply chain is composed of two contracts dependent mutually, i.e., the contract between the manufacturer and wholesaler and the contract between the wholesaler and retailer. The collaborative bargaining solution in the tandem supply chain consisting of three members is discussed. This paper, finally, formulates the tandem supply chain including several wholesalers. en-copyright= kn-copyright= en-aut-name=ArizonoIkuo en-aut-sei=Arizono en-aut-mei=Ikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoYasuhiko en-aut-sei=Takemoto en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University, kn-affil= affil-num=2 en-affil=Kindai University kn-affil= en-keyword=supply chain contract kn-keyword=supply chain contract en-keyword=collaborative coordination approach kn-keyword=collaborative coordination approach en-keyword=Nash bargaining solution kn-keyword=Nash bargaining solution en-keyword=Hessian matrix kn-keyword=Hessian matrix END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=4 article-no= start-page=894 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multifunctional Metallothioneins as a Target for Neuroprotection in Parkinson's Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson's disease (PD) is characterized by motor symptoms based on a loss of nigrostriatal dopaminergic neurons and by non-motor symptoms which precede motor symptoms. Neurodegeneration accompanied by an accumulation of alpha-synuclein is thought to propagate from the enteric nervous system to the central nervous system. The pathogenesis in sporadic PD remains unknown. However, many reports indicate various etiological factors, such as oxidative stress, inflammation, alpha-synuclein toxicity and mitochondrial impairment, drive neurodegeneration. Exposure to heavy metals contributes to these etiopathogenesis and increases the risk of developing PD. Metallothioneins (MTs) are cysteine-rich metal-binding proteins; MTs chelate metals and inhibit metal-induced oxidative stress, inflammation and mitochondrial dysfunction. In addition, MTs possess antioxidative properties by scavenging free radicals and exert anti-inflammatory effects by suppression of microglial activation. Furthermore, MTs recently received attention as a potential target for attenuating metal-induced alpha-synuclein aggregation. In this article, we summarize MTs expression in the central and enteric nervous system, and review protective functions of MTs against etiopathogenesis in PD. We also discuss neuroprotective strategies for the prevention of central dopaminergic and enteric neurodegeneration by targeting MTs. This review highlights multifunctional MTs as a target for the development of disease-modifying drugs for PD. en-copyright= kn-copyright= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=metallothionein kn-keyword=metallothionein en-keyword=Parkinson's disease kn-keyword=Parkinson's disease en-keyword=neuroprotection kn-keyword=neuroprotection en-keyword=antioxidant kn-keyword=antioxidant en-keyword=metal kn-keyword=metal en-keyword=synuclein kn-keyword=synuclein en-keyword=astrocyte kn-keyword=astrocyte en-keyword=enteric glial cell kn-keyword=enteric glial cell END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=5 article-no= start-page=523 end-page=526 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Buruli ulcer caused by Mycobacterium ulcerans subsp. shinshuense: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Buruli ulcer is the third most common mycobacterial infection worldwide and is mainly diagnosed in tropical regions. Globally, this progressive disease is caused by Mycobacterium ulcerans; however, Mycobacterium ulcerans subsp. shinshuense, an Asian variant, has been exclusively identified in Japan. Because of insufficient clinical cases, the clinical features of M. ulcerans subsp. shinshuense?associated Buruli ulcer remain unclear. A 70-year-old Japanese woman presented with erythema on her left backhand. The skin lesion deteriorated without an apparent etiology of inflammation, and she was referred to our hospital 3 months after disease onset. A biopsy specimen was incubated in 2% Ogawa medium at 30 °C. After 66 days, we detected small yellow-pigmented colonies, suggesting scotochromogens. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI Biotyper; Bruker Daltonics, Billerica, MA, USA) indicated that the organism was Mycobacterium pseudoshottsii or Mycobacterium marinum. However, additional PCR testing for the insertion sequence 2404 (IS2404) was positive, suggesting that the pathogen was either M. ulcerans or M. ulcerans subsp. shinshuense. Further examination by 16S rRNA sequencing analysis, focusing on nucleotide positions 492, 1247, 1288, and 1449?1451, we finally identified the organism as M. ulcerans subsp. shinshuense. The patient was successfully treated with 12 weeks of clarithromycin and levofloxacin treatment. Mass spectrometry is the latest microbial diagnostic method; however, it cannot be used to identify M. ulcerans subsp. shinshuense. To accurately detect this enigmatic pathogen and uncover its epidemiology and clinical characteristics in Japan, more accumulation of clinical cases with accurate identification of the causative pathogen is essential. en-copyright= kn-copyright= en-aut-name=FujimoriTakumi en-aut-sei=Fujimori en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamasakiOsamu en-aut-sei=Yamasaki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoYuji en-aut-sei=Miyamoto en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoshinoYoshihiko en-aut-sei=Hoshino en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KakehiAyaka en-aut-sei=Kakehi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkuraMami en-aut-sei=Okura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MinabeHiroshi en-aut-sei=Minabe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YokoyamaYukika en-aut-sei=Yokoyama en-aut-mei=Yukika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HigashikageAkihito en-aut-sei=Higashikage en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dermatology, Shimane University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Mycobacteriology, Leprosy Research Center, National Institute of Infectious Diseases kn-affil= affil-num=6 en-affil=Department of Mycobacteriology, Leprosy Research Center, National Institute of Infectious Diseases kn-affil= affil-num=7 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=8 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=9 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=10 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= en-keyword=Buruli ulcer kn-keyword=Buruli ulcer en-keyword=Mycobacterium ulcerans kn-keyword=Mycobacterium ulcerans en-keyword=Mycobacterium ulcerans subsp kn-keyword=Mycobacterium ulcerans subsp en-keyword=shinshuense kn-keyword=shinshuense en-keyword=16S rRNA sequencing analysis kn-keyword=16S rRNA sequencing analysis END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=21 article-no= start-page=e202303391 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230413 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bifunctional Iminophosphorane‐Catalyzed Enantioselective Nitroalkane Addition to Unactivated α,β‐Unsaturated Esters en-subtitle= kn-subtitle= en-abstract= kn-abstract=Herein we describe the enantioselective intermolecular conjugate addition of nitroalkanes to unactivated α,β-unsaturated esters, catalyzed by a bifunctional iminophosphorane (BIMP) superbase. The transformation provides the most direct access to pharmaceutically relevant enantioenriched γ-nitroesters, utilizing feedstock chemicals, with unprecedented selectivity. The methodology exhibits a broad substrate scope, including β-(fluoro)alkyl, aryl and heteroaryl substituted electrophiles, and was successfully applied on a gram scale with reduced catalyst loading, and, additionally, catalyst recovery was carried out. The formal synthesis of a range of drug molecules, and an enantioselective synthesis of (S)-rolipram were achieved. Additionally, computational studies revealed key reaction intermediates and transition state structures, and provided rationale for high enantioselectivities, in good agreement with experimental results. en-copyright= kn-copyright= en-aut-name=RozsarDaniel en-aut-sei=Rozsar en-aut-mei=Daniel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FarleyAlistair J.

Methods: We recruited 143 Japanese university students in 2021 and assigned them to sleep bruxism (n = 58) and non-sleep bruxism groups (n = 85), using an identical single-channel wearable electromyography device. To investigate nutrient intakes, participants answered a food frequency questionnaire based on food groups. We assessed differences in nutrient intakes between the sleep bruxism and non-sleep bruxism groups. Results: Logistic regression modeling showed that sleep bruxism tended to be associated with dietary fiber (odds ratio, 0.91; 95% confidence interval, 0.83-1.00; p = 0.059). In addition, a subgroup analysis selecting students in the top and bottom quartiles of dietary fiber intake showed that students with sleep bruxism had a significantly lower dietary fiber intake (10.4 +/- 4.6 g) than those without sleep bruxism (13.4 +/- 6.1 g; p = 0.022). Conclusion: The present research showed that dietary fiber intake may be related to sleep bruxism. Therefore, we hypothesized that dietary fiber would improve sleep bruxism in young adults. en-copyright= kn-copyright= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuharaDaiki en-aut-sei=Fukuhara en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaMiho en-aut-sei=Yamashita en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomiyamaMomoe en-aut-sei=Komiyama en-aut-mei=Momoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagahamaTakahiko en-aut-sei=Nagahama en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Foods and Human Nutrition, Notre Dame Seishin University kn-affil= affil-num=6 en-affil=Department of Foods and Human Nutrition, Notre Dame Seishin University kn-affil= affil-num=7 en-affil=Department of Foods and Human Nutrition, Notre Dame Seishin University kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=sleep bruxism kn-keyword=sleep bruxism en-keyword=dietary fiber kn-keyword=dietary fiber en-keyword=electromyography kn-keyword=electromyography en-keyword=young adult kn-keyword=young adult en-keyword=biostatistics kn-keyword=biostatistics en-keyword=nutrition assessment kn-keyword=nutrition assessment END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=4 article-no= start-page=417 end-page=422 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationships between squamous cell carcinoma antigen and cytokeratin 19 fragment values and renal function in oral cancer patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragment (CYFRA) are used to screen and monitor oral cancer patients. However, recent studies have reported that tumour markers become elevated as renal function decreases, regardless of tumour progression. A retrospective study was performed of 423 oral cancer patients who underwent blood testing for these tumour markers and other blood analytes during a 10-year period. The values of SCC-Ag and CYFRA increased significantly with decreasing renal function (P < 0.01), and the values were abnormal at a median 2.6 ng/ml for SCC-Ag and 4.7 ng/ml for CYFRA in the group with estimated glomerular filtration rate (eGFR) values of< 30 ml/min/1.73 m2. The factors that were related to the variation in tumour markers were albumin and creatinine. The cut-off values of eGFR were 59.7 ml/min/1.73 m2 for SCC-Ag and 63.6 ml/min/1.73 m2 for CYFRA, and the cut-off age when the tumour markers might rise due to the effect of renal function were 72 years for SCC-Ag and 73 years for CYFRA. In conclusion, decreased renal function should be taken into account when evaluating tumour markers in oral cancer. In addition, tumour markers are likely to be overestimated in patients over the age of 72?73 years. en-copyright= kn-copyright= en-aut-name=ObataK. en-aut-sei=Obata en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YutoriH. en-aut-sei=Yutori en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaK. en-aut-sei=Yoshida en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoY. en-aut-sei=Sakamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoK. en-aut-sei=Ono en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IbaragiS. en-aut-sei=Ibaragi en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Oral cancer kn-keyword=Oral cancer en-keyword=Tumor markers kn-keyword=Tumor markers en-keyword=Squamous cell carcinoma kn-keyword=Squamous cell carcinoma en-keyword=Tumor antigens kn-keyword=Tumor antigens en-keyword=CYFRA cytokeratin fragment kn-keyword=CYFRA cytokeratin fragment en-keyword=Renal function kn-keyword=Renal function END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=3 article-no= start-page=166 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case of duodenal diverticulitis in a patient receiving tocilizumab for rheumatoid arthritis kn-title=トシリズマブ投与中に十二指腸憩室炎を認めた1例 en-subtitle= kn-subtitle= en-abstract= kn-abstract= A Japanese woman was diagnosed with rheumatoid arthritis at the age of 41. At the age of 56, her rheumatoid arthritis worsened and a subcutaneous injection of tocilizumab and oral prednisolone was administered, which led to an improvement of arthritis. At the age of 57, right lower abdominal pain and vomiting suddenly appeared. Abdominal computed tomography showed a parapapillary diverticulum in the descending duodenum. The diverticulum was filled with residue, and an inflammation of the surrounding adipose tissue was observed; no free air was found. The patient was diagnosed with duodenal diverticulitis and treated with antibiotics, which resulted in an uneventful recovery. The maximum value of CRP was 1.88r/dL on the third day of hospitalization. Esophagogastroduodenoscopy performed on the 8th day of hospitalization revealed a parapapillary diverticulum with adhesion of pus and redness of the mucosa at the opening of the diverticulum, consistent with diverticulitis. This case highlights that diverticulitis in infrequent areas such as the duodenum may occur in patients who are treated with tocilizumab. In addition, inflammation of diverticulitis may be underestimated because abnormal laboratory values such as those induced by inflammatory reactions are less likely to occur during tocilizumab treatment. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name=岩室雅也 kn-aut-sei=岩室 kn-aut-mei=雅也 aut-affil-num=1 ORCID= en-aut-name=BabaYuki en-aut-sei=Baba en-aut-mei=Yuki kn-aut-name=馬場雄己 kn-aut-sei=馬場 kn-aut-mei=雄己 aut-affil-num=2 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name=河原祥朗 kn-aut-sei=河原 kn-aut-mei=祥朗 aut-affil-num=3 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name=岡田裕之 kn-aut-sei=岡田 kn-aut-mei=裕之 aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil=岡山大学病院 消化器内科 affil-num=2 en-affil=Department of Internal Medicine, Mitoyo General Hospital kn-affil=三豊総合病院 内科 affil-num=3 en-affil=Department of Practical Gastrointestinal Endoscopy, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 実践地域内視鏡学講座 affil-num=4 en-affil=Professor Emeritus, Okayama University kn-affil=岡山大学 名誉教授 en-keyword=トシリズマブ(tocilizumab) kn-keyword=トシリズマブ(tocilizumab) en-keyword=十二指腸憩室(duodenal diverticulum) kn-keyword=十二指腸憩室(duodenal diverticulum) en-keyword=憩室炎(diverticulitis) kn-keyword=憩室炎(diverticulitis) END
