In this study, a quantitative structure–activity relationship (QSAR) model was developed to identify potential Nrf2 activators from food-derived compounds. Machine learning algorithms, including Random Forest (RF), Support Vector Machine (SVM), Linear Discriminant Analysis (LDA), and a stacking model, were developed and optimized. The optimized RF, SVM, and LDA models were subsequently integrated into a stacking framework, which was selected as the final predictive model for virtual screening based on its robust and balanced predictive performance. The stacking model achieved the highest accuracy during five-fold cross-validation (0.77) and demonstrated competitive performance on the independent test set (0.742 ± 0.040), with balanced precision, sensitivity, and F-measure. Consequently, the stacking model was selected as the final model for virtual screening. A total of 70,926 compounds retrieved from a food-derived database were filtered based on physicochemical criteria, and QSAR-based virtual screening predicted 920 compounds as potential activators of the Nrf2 signaling pathway, from which 5,7-Dimethylchrysin (FooDB ID: FDB015537) and Demethylvestitol (FooDB ID: FDB012218) were selected for experimental validation. In vitro assays using HepG2 cells demonstrated that 5,7-Dimethylchrysin significantly enhanced cell viability against sodium arsenite (150 μM)-induced cytotoxicity, with an effective concentration (EC50) of 0.54 μM, whereas Demethylvestitol exhibited only limited protective effects. Furthermore, luciferase reporter assays confirmed that 5,7-Dimethylchrysin activated antioxidant response element (ARE)-driven transcription in a concentration-dependent manner, producing a 1.5 to 2.4-fold increase at concentrations ranging from 0.78 to 6.25 μM. Overall, these findings highlight the effectiveness of integrating QSAR modeling with experimental validation to identify food-derived compounds with protective potential against arsenic-induced toxicity, with 5,7-Dimethylchrysin emerging as a promising candidate for further investigation. en-copyright= kn-copyright= en-aut-name=HuongNgo Thanh en-aut-sei=Huong en-aut-mei=Ngo Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KodamaSusumu en-aut-sei=Kodama en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoAtsushi en-aut-sei=Ono en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Laboratory of Toxicology, Division of Pharmaceutical Sciences, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Toxicology, Division of Pharmaceutical Sciences, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Toxicology, Division of Pharmaceutical Sciences, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Arsenic toxicity kn-keyword=Arsenic toxicity en-keyword=Nrf2 activator kn-keyword=Nrf2 activator en-keyword=QSAR modeling kn-keyword=QSAR modeling en-keyword=Food-derived compounds kn-keyword=Food-derived compounds en-keyword=In vitro kn-keyword=In vitro END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=1944754 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20261012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Navigating inherited “intensive surveillance” within Japan's structural norms of autonomy: maternal identity negotiation among long-term Peruvian migrant mothers (1990–2025) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: This study examines how Peruvian mothers who have settled in Japan for decades rework their identities as mothers. These women were raised with the belief that being a good mother means constantly watching over and protecting their children. But in Japan, child-rearing pushes children toward independence from a young age. This study asks: What happens when these two different approaches of mothering meet?
Methods: We interviewed 21 Peruvian mothers who had lived in Japan for 17–35 years.
Results: The analysis identified four identity positions to this cultural friction. The first is holding firmly to Peruvian maternal scripts (“Ideological Retention”). The second is following Japanese conventions in public while keeping Peruvian ways at home (“Compartmentalization”). The third is moving away from inherited protective scripts and adopting Japanese norms of independence (“Assimilation”). The fourth is blending elements of both into a maternal self that is “neither the one nor the other” (a “Third Space”).
Discussion: This study helps us understand that migrant mothers do not simply choose between their home and new cultures. Instead, they actively work to create a way of mothering through a process we call Reflexive Continuity that makes sense for their unique situations. en-copyright= kn-copyright= en-aut-name=Huaman PalominoKatia Sara en-aut-sei=Huaman Palomino en-aut-mei=Katia Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirataYoshitsugu en-aut-sei=Hirata en-aut-mei=Yoshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= en-keyword=acculturation kn-keyword=acculturation en-keyword=intensive surveillance kn-keyword=intensive surveillance en-keyword=Japan kn-keyword=Japan en-keyword=maternal identity kn-keyword=maternal identity en-keyword=Peruvian migration kn-keyword=Peruvian migration en-keyword=reflexive continuity kn-keyword=reflexive continuity en-keyword=Third Space kn-keyword=Third Space en-keyword=transnational motherhood kn-keyword=transnational motherhood END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=6 article-no= start-page=835 end-page=844 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Impact of Genetic Testing for Long QT Syndrome　― Evidence From a Nationwide LQTS Registry in Japan ― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Genetic testing for long QT syndrome (LQTS) is useful for diagnosis, risk stratification, and therapeutic strategies. This study investigated the clinical impact of genetic testing for LQTS patients.
Methods and Results: Total 3,851 patients (proband: 2,316 [60%]; female: 2,283 [59%]; median age: 14 years [interquartile range 9–36 years]) diagnosed with LQTS (LQTS score ≥3.5, QTc ≥500 ms, pathogenic variants in LQTS-associated genes, or unexplored syncope with QTc 480–499 ms) were enrolled in this study. Of these patients, 1,146 (29.8%) experienced syncope and 322 (8.5%) experienced ventricular fibrillation (VF) or cardiopulmonary arrest (CPA) at ≤70 years of age. Genetic testing using a next-generation sequencing panel and/or Sanger sequencing was performed for 3,770 (98%) patients, genotype was then identified in the following LQTS-associated genes: KCNQ1 (45%), KCNH2 (34%), SCN5A (8%), KCNE1 (0.1%), KCNE2 (0.03%), KCNJ2 (2.7%), CACNA1C (1.2%), and CALM1,2 (0.3%). Forty-seven (1.2%) patients had double or compound heterozygous variants in LQTS-associated genes, whereas the genotype remained unknown in 220 (5.8%) patients. When comparing phenotype with genotype, QTc was significantly longer in CALM1,2 patients than in others except for CACNA1C, whereas QTc was almost normal in KCNJ2 patients. The incidence of the first cardiac event (syncope, VF/CPA) differed among the genotypes, and prognosis was significantly worse for CALM1,2 patients.
Conclusions: Comprehensive genetic testing, including non-major LQTS genes, is important for diagnosis and risk stratification of LQTS. en-copyright= kn-copyright= en-aut-name=AibaTakeshi

kn-title=Rapid fluvial response to meter-scale coseismic coastal uplift during the 2024 Noto Peninsula earthquake en-subtitle= kn-subtitle= en-abstract= kn-abstract=The response of river profiles to relative base-level change is a key topic in earth surface processes, but observations capturing these changes on unconsolidated deposits at a 1–10 years timescales are scarce. We monitored geomorphic changes at the Hakka River mouth after the 3.5-meter base-level fall caused by coseismic uplift of the 2024 Noto Peninsula earthquake, Japan. Utilizing uncrewed aerial vehicle surveys, we documented a maximum vertical riverbed lowering of 2 m and knickpoint upstream migration of 770-m within the first-year post-earthquake, primarily triggered by erosion during major floods that followed the earthquake. Our findings demonstrate that fluvial terraces can develop within a year or less, following co-seismic coastal uplift. However, the river has not yet reached a renewed graded stage because riverbed armoring resulting from sediment sorting during incision currently inhibits further incision. We suggest that the abandonment of alluvial plains and lowering and widening of the riverbed in the lower 10-km segment will continue over the next decade. en-copyright= kn-copyright= en-aut-name=TakahashiTakayuki en-aut-sei=Takahashi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OguraTakuro en-aut-sei=Ogura en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IizukaKotaro en-aut-sei=Iizuka en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwasaYoshiya en-aut-sei=Iwasa en-aut-mei=Yoshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayakawaYuichi S. en-aut-sei=Hayakawa en-aut-mei=Yuichi S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AokiTatsuto en-aut-sei=Aoki en-aut-mei=Tatsuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=International Research Institute of Disaster Science, Tohoku University kn-affil= affil-num=2 en-affil=Graduate School of Social Sciences, Hitotsubashi University kn-affil= affil-num=3 en-affil=Center for Spatial Information Science, The University of Tokyo kn-affil= affil-num=4 en-affil=Faculty of Education, University of Teacher Education Fukuoka kn-affil= affil-num=5 en-affil=Center for Spatial Information Science, The University of Tokyo kn-affil= affil-num=6 en-affil=Institute of Human and Social Sciences, Kanazawa University kn-affil= affil-num=7 en-affil=Graduate School of Education, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=526 cd-vols= no-issue= article-no= start-page=150819 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flavor encapsulation capacities of amphiphilic polyvinylpyrrolidone as a carrier for amorphous solid dispersions en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates the characteristics of amorphous solid dispersions (ASDs) formed using an amphiphilic carrier polymer, focusing on the effects of source solution conditions on flavor retention. Cinnamaldehyde and polyvinylpyrrolidone (PVP) were dissolved as flavor and carrier components in methanol or ethanol under different conditions and subsequently spray-dried into fine powders. The amount of cinnamaldehyde retained in the spray-dried ASDs was quantified to assess the impact of solution conditions. The results indicate that cinnamaldehyde molecules were physically entrapped within the entangled PVP chains during the spray-drying process. The flavor encapsulation capacity of PVP reached a maximum of approximately 4 mmol/g-PVP under specific conditions. This maximum capacity implies that each cinnamaldehyde molecule is associated with approximately two PVP monomer units, which is higher than those reported for selected cyclodextrin-based systems in comparable contexts of cinnamaldehyde encapsulation. Additionally, the dissipation of cinnamaldehyde from the ASD samples during storage under vacuum was examined. en-copyright= kn-copyright= en-aut-name=SatoHaruna en-aut-sei=Sato en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaNao en-aut-sei=Honda en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaTakato en-aut-sei=Hasegawa en-aut-mei=Takato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AragaChika en-aut-sei=Araga en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ImanakaHiroyuki en-aut-sei=Imanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshidaNaoyuki en-aut-sei=Ishida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ImamuraKoreyoshi en-aut-sei=Imamura en-aut-mei=Koreyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Chemical Engineering and Material Sciences, Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=7 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Flavor encapsulation kn-keyword=Flavor encapsulation en-keyword=Polyvinylpyrrolidone kn-keyword=Polyvinylpyrrolidone en-keyword=Spray-drying kn-keyword=Spray-drying en-keyword=Encapsulation capacity kn-keyword=Encapsulation capacity en-keyword=Overlap concentration kn-keyword=Overlap concentration en-keyword=Encapsulation pocket kn-keyword=Encapsulation pocket 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=2026 dt-pub=20260930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Amino acid mapping–guided scaffold selection and hit identification of histidine kinase inhibitors from a virtual library of over 12 million compounds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Waldiomycin is a natural product originally isolated from actinomycete extracts. It inhibits histidine kinases (HKs), which are essential components of bacterial two-component signal transduction systems, by targeting the conserved H-box region and suppressing autophosphorylation. Here, we identified novel HK inhibitors using amino acid mapping (AAM)-based virtual screening. We compared the AAM descriptor of the naphthoquinone moiety of waldiomycin, which directly interacts with the H-box region, with those of approximately 12 million commercially available compounds and identified 714 candidates with similar descriptor values. From these candidates, we selected 9-hydroxy-4H-pyrido[1,2-a]pyrimidin-4-one as a promising and structurally distinct scaffold and synthesized 15 derivatives. The inhibitory activities of these derivatives were evaluated against the HKs WalK, VicK, and EnvZ. Three 4H-pyrido[1,2-a]pyrimidin-4-one derivatives (FF-054, FF-055, and FF-060) exhibited potent inhibitory activity, with IC50 values ranging from 4.39 to 259 µM. Notably, the IC50 values of these compounds increased three- to six-fold against the EnvZ S242A mutant, in which the conserved H-box residue is substituted. Furthermore, nuclear magnetic resonance (NMR) analysis using the EnvZ DHp domain (residues 223–289, encompassing the H-box region) confirmed direct interaction with this domain. Taken together, these results demonstrate that pyrido[1,2-a]pyrimidin-4-one derivatives FF-054, FF-055, and FF-060 are novel HK inhibitors that target the H-box region. This study represents the first successful application of AAM-based screening to identify HK inhibitors targeting this highly conserved region. en-copyright= kn-copyright= en-aut-name=IshikawaTeruhiko

security and dietary habits and subjective health and subjective well-being among residents of a large-scale housing complex in Japan. Methods: This study used a cross-sectional design through a self-administered questionnaire survey. The study subjects were residents of Mukogawa Danchi in Nishinomiya City, Hyogo Prefecture, Japan, and data from 515 households out of 6,857 total dwelling units were used for the analysis. Food security status (HFSSM), dietary diversity score (HDDS), diet, eating behavior, subjective sense of health, and subjective sense of well-being were examined using logistic regression analysis. Results: Food insecurity was negatively associated with household dietary diversity scores (OR [95%CI]:0.49 [0.24–0.98] p = 0.044). Similarly, food insecurity was negatively associated with having a nutritionally balanced diet and having a satisfactory amount of food. There was also a negative association with family meals. There was a negative association between food insecurity and a subjective sense of health and a negative association (0.35 [0.15–0.78] p = 0.011) with a subjective sense of well-being among those aged 65 and older. Conclusions: In a large-scale housing complex in Japan, inadequate dietary intake was observed in food-insecure households; they ate meals less frequently with their families. Additionally, residents experiencing food insecurity tended to have lower subjective health and subjective well-being, depending on their age. en-copyright= kn-copyright= en-aut-name=WakimotoKeiko en-aut-sei=Wakimoto en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Yokoro-HisanariMiyuki en-aut-sei=Yokoro-Hisanari en-aut-mei=Miyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtsuboAkira en-aut-sei=Ohtsubo en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiTatsuya en-aut-sei=Fujii en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoJotaro en-aut-sei=Kato en-aut-mei=Jotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgasawaraHitoshi en-aut-sei=Ogasawara en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KudoDaisuke en-aut-sei=Kudo en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukuiMinae en-aut-sei=Fukui en-aut-mei=Minae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujitaYuichi en-aut-sei=Fujita en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=School of Food Sciences and Nutrition, Mukogawa Women’s University kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=3 en-affil=Community Liaison Division for Education and Research, Mukogawa Women’s University kn-affil= affil-num=4 en-affil=School of Education, Mukogawa Women’s University kn-affil= affil-num=5 en-affil=School of Letters, Mukogawa Women’s University kn-affil= affil-num=6 en-affil=School of Nursing, Mukogawa Women’s University kn-affil= affil-num=7 en-affil=School of Nursing Science, Meiji University of Integrative Medicine kn-affil= affil-num=8 en-affil=Ichikan Nursing Development center for Diversity, Kobe City College of Nursing kn-affil= affil-num=9 en-affil=School of Nursing, Mukogawa Women’s University kn-affil= en-keyword=food security kn-keyword=food security en-keyword=dietary quality kn-keyword=dietary quality en-keyword=eating behavior kn-keyword=eating behavior en-keyword=self-rated health kn-keyword=self-rated health END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=263 end-page=267 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preoperative Nutritional Status Influences Enteral Nutrition Weaning 6 Months Post-Surgery in Patients with Esophageal Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer. Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy). Results: The enteral nutrition withdrawal rate after 6 months was 15.5% in the malnutrition group and 84.5% in the normal nutrition group (p = 0.007). In a comparison between groups with and without enteral nutrition after 6 months, a significant association was observed with surgical procedure, nutritional status at admission, and postoperative complications (p < 0.05). Logistic regression analysis showed that the odds of discontinuing enteral nutrition 6 months later were 5.692 (hazard ratio: 1.545–20.962) for malnutrition on admission and 11.921 (hazard ratio: 3.449–41.207) for complications. Conclusion: Regardless of the presence or absence of treatment other than surgery, preoperative nutritional improvement is beneficial for increasing postoperative oral intake. en-copyright= kn-copyright= en-aut-name=SonoiMika en-aut-sei=Sonoi en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SonoiNorihiro en-aut-sei=Sonoi en-aut-mei=Norihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Foods and Human Nutrition, Faculty of Human Life Sciences, Notre Dame Seishin University kn-affil= affil-num=2 en-affil=Department of Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=3 en-affil=Center for Education in Medicine and Health Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Enteral nutrition kn-keyword=Enteral nutrition en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=Geriatric nutritional risk index kn-keyword=Geriatric nutritional risk index en-keyword=Preoperative management kn-keyword=Preoperative management en-keyword=Preoperative nutritional status kn-keyword=Preoperative nutritional status END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=3 article-no= start-page=276 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Influence of Educational Films on Antiviral Prescription for COVID-19: Insights from Web-Based Survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Prescribing antiviral agents for severe acute respiratory syndrome coronavirus 2 requires careful consideration based on the patient’s risk factors for severe disease progression and their vaccination status. However, effective interventions ensuring the appropriate use of antiviral agents by physicians have yet to be fully established. Thus, this study evaluated the impact of an educational film on antiviral prescription rates for coronavirus disease 2019 (COVID-19). Methods: This prospective, nationwide, web-based survey enrolled 1500 physicians. They were instructed to view a short educational film and assess the necessity of prescribing antiviral agents in 16 fictitious scenarios featuring adult patients with COVID-19 with varying risk factors for severe disease and vaccination statuses. We compared the antiviral prescription rates before and after viewing the educational film. Results: There was a significant increase in the antiviral prescription rates after viewing the educational film, particularly nirmatrelvir/ritonavir prescribed in cases involving immunocompromised patients (from 31.3% to 49.4%) and those with obesity (from 15.1% to 33.7%) who were unvaccinated and had no risk of drug interactions. However, viewing the educational film made little to no impact on the prescription rates for the patients with hypertension and hyperlipidemia or those with no underlying conditions. Conclusions: Short educational films may promote the appropriate use of antiviral agents for COVID-19. However, their impact on altering prescription behavior appears limited and varies according to the clinical context. en-copyright= kn-copyright= en-aut-name=KomiyaKosaku en-aut-sei=Komiya

Charge-Ordered Kagome Metal CsV3⁢Sb5 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The nature of the superconducting pairing symmetry in the kagome metal CsV3⁢Sb5 and its relationship with the charge density wave (CDW) order are central unresolved issues. Here, we investigate the evolution of superconductivity in CsV3⁢Sb5 under in situ uniaxial pressure using 121Sb nuclear quadrupole resonance (NQR). We find that tensile strain significantly enhances the superconducting transition temperature, 𝑇c, while the CDW remains unchanged, demonstrating that superconductivity can be tuned independently of the bulk charge order. At a tensile strain of 𝜖 =+0.90%, the nuclear spin-lattice relaxation rate reveals a remarkable double transition: an upper transition at 𝑇c⁢1=3.6  K to a nodal gap state, and a lower one at 𝑇c⁢2=3.0  K characterized by a nodeless gap. These results evidence degenerate superconducting states with different gap symmetry in the kagome metal at ambient pressure which split under strain. Our Letter demonstrates a high tunability of superconductivity by uniaxial pressure. en-copyright= kn-copyright= en-aut-name=TakeuchiYusuke en-aut-sei=Takeuchi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiAkito en-aut-sei=Kobayashi en-aut-mei=Akito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UchidaSaki en-aut-sei=Uchida en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaoTakumi en-aut-sei=Nagao en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaSeigo en-aut-sei=Ogawa en-aut-mei=Seigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhouRui en-aut-sei=Zhou en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawasakiShinji en-aut-sei=Kawasaki en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SongFei en-aut-sei=Song en-aut-mei=Fei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NiHao en-aut-sei=Ni en-aut-mei=Hao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ZhaoYong en-aut-sei=Zhao en-aut-mei=Yong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZhengGuo-qing en-aut-sei=Zheng en-aut-mei=Guo-qing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=Department of Physics, Okayama University kn-affil= affil-num=6 en-affil=Institute of Physics, Chinese Academy of Sciences, and Beijing National Laboratory for Condensed Matter Physics kn-affil= affil-num=7 en-affil=Department of Physics, Okayama University kn-affil= affil-num=8 en-affil=Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering, College of Physics and Energy, Fujian Normal University kn-affil= affil-num=9 en-affil=Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering, College of Physics and Energy, Fujian Normal University kn-affil= affil-num=10 en-affil=Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering, College of Physics and Energy, Fujian Normal University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=3 article-no= start-page=405 end-page=421 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Practical Guidelines for Asthma Management (PGAM): Digest edition en-subtitle= kn-subtitle= en-abstract= kn-abstract=The international and national guidelines for asthma management are typically comprehensive and designed for respiratory specialists, making them less practical for primary care physicians who handle most asthma cases. Recognizing the need for more accessible guidelines, the Japan Asthma Society developed the Practical Guidelines for Asthma Management (PGAM). PGAM aims to provide a concise summary of key asthma management principles, increasing awareness, education, and support among nonspecialists and patients alike. It includes user-friendly tables and lists outlining common symptoms, triggers, diagnostic criteria, and basic management strategies, along with frequently encountered treatable traits and comorbidities. These elements are presented through simple, clinically relevant algorithms. A notable feature of PGAM is the “Basic Roadmap for Asthma Management,” which outlines a clear sequence for patient assessment, diagnosis, and treatment from initial consultation onward, offering an easy-to-follow visual guide. Additionally, the guidelines include methods for assessing airway inflammation, enabling patient phenotyping and endotyping. This supports a personalized treatment approach, particularly with biologics, aimed at achieving clinical remission. en-copyright= kn-copyright= en-aut-name=TamaokiJun en-aut-sei=Tamaoki en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaseHiroyuki en-aut-sei=Nagase en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SanoHiroyuki en-aut-sei=Sano en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanekoTakeshi en-aut-sei=Kaneko en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GonYasuhiro en-aut-sei=Gon en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SagaraHironori en-aut-sei=Sagara en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaAkihiko en-aut-sei=Tanaka en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HoriguchiTakahiko en-aut-sei=Horiguchi en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TagayaEtsuko en-aut-sei=Tagaya en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkabaTomohiro en-aut-sei=Akaba en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TohdaYuji en-aut-sei=Tohda en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, Tokyo Women's Medical University kn-affil= affil-num=2 en-affil=Division of Respiratory Medicine and Allergology, Department of Medicine, Teikyo University School of Medicine kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine and Allergology, Kindai University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Pulmonology, Yokohama City University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Division of Respiratory Medicine, Department of Internal Medicine, Nihon University School of Medicine 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 Medicine, Division of Allergology and Respiratory Medicine, School of Medicine, Showa University kn-affil= affil-num=8 en-affil=Department of Medicine, Division of Allergology and Respiratory Medicine, School of Medicine, Showa University kn-affil= affil-num=9 en-affil=Department of Respiratory Medicine, Toyota Regional Medical Center kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Tokyo Women's Medical University kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Tokyo Women's Medical University kn-affil= affil-num=12 en-affil=Kindai University Hospital kn-affil= en-keyword=Asthma kn-keyword=Asthma en-keyword=Clinical remission kn-keyword=Clinical remission en-keyword=Management guidelines kn-keyword=Management guidelines en-keyword=Treatment algorithm kn-keyword=Treatment algorithm en-keyword=Practical tool kn-keyword=Practical tool END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=6 article-no= start-page=e70681 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bridging the Awareness–Action Gap in Disaster Preparedness: A Qualitative Study of Immersive Virtual Reality Learning Among Nursing Students en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Disasters increasingly challenge healthcare systems, highlighting the need to strengthen preparedness among future healthcare professionals. Although disaster risk awareness is important, it does not consistently translate into preparedness behaviours, reflecting the awareness–action gap. Immersive virtual reality (VR) may enhance experiential disaster learning, but how it influences preparedness processes remains insufficiently understood, particularly in healthcare and critical care education.
Aims: To explore how immersive VR-based disaster simulations influence disaster risk perception and preparedness among nursing students, with particular attention to the awareness–action gap and implications for future healthcare and critical care practice.
Study Design: A qualitative descriptive study using immersive VR-based disaster simulations followed by semi-structured interviews. Twelve undergraduate and graduate nursing students in Japan experienced immersive VR simulations depicting floods and landslides. Individual semi-structured interviews explored emotional responses, disaster risk perception, preparedness awareness and anticipated behavioural responses. Data were analysed using Krippendorff's content analysis with researcher triangulation.
Results: Five categories were identified: (1) heightened vulnerability and psychological burden through immersion; (2) persistence of the awareness–action gap despite increased risk perception; (3) enhanced risk recognition and preparedness intentions; (4) recognition of the need for social and structural support systems; and (5) emerging responsibility accompanied by perceived limitations. VR transformed abstract disaster risk into emotionally salient experiences, strengthening threat appraisal and preparedness awareness; however, awareness did not consistently translate into preparedness behaviours, reflecting insufficient coping appraisal and self-efficacy.
Conclusions: Immersive VR may strengthen disaster risk perception and preparedness awareness, but immersive experiences alone may be insufficient to bridge the awareness–action gap. Combining VR with reflective learning, skills-based training and collaborative simulation may strengthen coping appraisal and preparedness action.
Relevance to Clinical Practice: Immersive VR combined with reflective and skills-based learning may support psychological readiness, situational awareness and disaster preparedness competencies among future nurses, including those preparing for critical care practice. en-copyright= kn-copyright= en-aut-name=MoriKeiko en-aut-sei=Mori en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiMiina en-aut-sei=Yamazaki en-aut-mei=Miina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HarunaYoshiyuki en-aut-sei=Haruna en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Kobe University Hospital kn-affil= affil-num=3 en-affil=Snowlion.

Although the mechanisms underlying cardiac ischaemia–reperfusion injury have been intensively investigated, effective therapeutic strategies applicable during reperfusion to mitigate this damage have not been established yet. To obtain more insights into the mechanisms underlying ischaemia–reperfusion injury, and to explore effective methods to relieve reperfusion injury, we developed a comprehensive mathematical model of ventricular myocyte, implementing excitation–contraction (E–C) coupling, cytosolic and mitochondrial pH regulation, pH dependence of major components of E–C coupling and cellular energy metabolism, including mitochondrial oxidative phosphorylation. The mathematical model successfully reproduced experimentally observed findings on cardiac ischaemia–reperfusion injury, such as intracellular and extracellular acidosis, cytosolic Na+ overload, cytosolic Ca2+ overload, mitochondrial dysfunction, action potential shortening and contraction failure. It was found that the reperfusion-induced exacerbation of Na+i, Ca2+i overloads was mainly caused by insufficient production of NADH, which is used in mitochondrial oxidative phosphorylation to synthesize ATP for Na+/K+ pump and sarcoplasmic/endoplasmic reticulum Ca2+ pump (SERCA) to expel accumulated cytosolic Na+ and Ca2+, respectively. It was suggested that the preservation of mitochondrial NADH production, attenuation of ATP consumption via SERCA or contraction for a short period or activation of the Na+/K+ pump during reperfusion mitigates reperfusion injury. en-copyright= kn-copyright= en-aut-name=ShimayoshiTakao en-aut-sei=Shimayoshi en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiAyako en-aut-sei=Takeuchi en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuokaSatoshi en-aut-sei=Matsuoka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Physiology and Biophysics, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Integrative and Systems Physiology, Faculty of Medical Sciences, University of Fukui kn-affil= en-keyword=computational modelling kn-keyword=computational modelling en-keyword=heart kn-keyword=heart en-keyword=ischaemia kn-keyword=ischaemia en-keyword=mitochondria kn-keyword=mitochondria en-keyword=reperfusion kn-keyword=reperfusion 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=2026 dt-pub=20260623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term association between the COVID-19 pandemic and language development at 3 years of age en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Few studies have examined the long-term association between the COVID-19 pandemic and language development in preschoolers or its effect modifiers. We therefore examined this association during health checkups of 3-year-olds in Japan.
Methods: This repeated cross-sectional study included 40,898 3-year-olds who underwent checkups in Okayama City, Japan. We compared children examined before (2017–2019) and during the pandemic (2020–2023). The primary outcome was physician-determined risk of language difficulties. The secondary outcome was children’s infrequent questions using words such as “what,” “who,” and “where.” Modified Poisson regression estimated RRs adjusted for confounders. Subgroup analyses examined effect modification by sex, childcare setting, and family size.
Results: The COVID-19 pandemic was associated with increased risk of language difficulties (RR 1.52, 95% CI 1.35–1.72). The association peaked in fiscal year 2021 and remained elevated throughout the pandemic. Secondary outcome showed elevated risk (RR 1.16, 95% CI 1.05–1.29). Girls and home-care children showed higher RRs than boys and preschool attendees.
Conclusions: The COVID-19 pandemic was associated with risk of language difficulties among 3-year-old children, with associations varying by sex and childcare setting. These findings suggest the importance of maintaining social interaction opportunities for young children during public health crises. en-copyright= kn-copyright= en-aut-name=MatsuoRumi en-aut-sei=Matsuo en-aut-mei=Rumi 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=NakamuraKazue en-aut-sei=Nakamura en-aut-mei=Kazue 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=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, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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, 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= END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=8 article-no= start-page=1285 end-page=1290 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260825 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Adjusted Creatinine Clearance on Carboplatin Dosing in Endometrial Cancer: A Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Carboplatin (CBDCA) dosing is commonly determined using the Calvert formula, with creatinine clearance (Ccr) estimated by the Cockcroft–Gault formula. In Japan, where serum creatinine (sCr) is usually measured enzymatically, unadjusted Ccr may overestimate glomerular filtration rate and lead to CBDCA overdosing. We retrospectively compared treatment exposure, hematologic toxicity, and exploratory oncologic outcomes in patients with endometrial cancer who received postoperative paclitaxel plus CBDCA therapy. Patients were grouped according to whether CBDCA dosing was based on the conventional Cockcroft–Gault formula (CG group) or on adjusted Ccr calculated by adding 0.2 mg/dL to sCr (adjusted group). The incidence of Grade ≥3 neutropenia was significantly lower in the adjusted group than in the CG group. The 5-year progression-free survival (PFS) rate was numerically lower in the adjusted group than in the CG group, although no statistically significant difference was observed between the groups. Because the number of PFS events was limited, the effect of adjusted Ccr-based dosing on oncologic outcomes remains uncertain. These findings suggest that adjusted Ccr-based dosing may reduce hematologic toxicity in routine clinical practice. However, given the limited number of PFS events and the wide uncertainty in survival estimates, further studies are needed to clarify its impact on oncologic outcomes. en-copyright= kn-copyright= en-aut-name=KatayamaKentaro en-aut-sei=Katayama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImamuraMakio en-aut-sei=Imamura en-aut-mei=Makio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara 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 Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Clinical Support, Kurashiki Medical Center kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=carboplatin kn-keyword=carboplatin en-keyword=creatinine clearance kn-keyword=creatinine clearance en-keyword=dose adjustment kn-keyword=dose adjustment en-keyword=endometrial cancer kn-keyword=endometrial cancer en-keyword=neutropenia kn-keyword=neutropenia en-keyword=pharmaceutical care kn-keyword=pharmaceutical care END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=13 article-no= start-page=317 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intensity of chemical weathering and its implications for soil erosion across lithological and climatic gradients in the Chemoga watershed, Upper Blue Nile Basin en-subtitle= kn-subtitle= en-abstract= kn-abstract=The geochemistry of rocks, regolith/soil, surficial and core sediments, and clay mineral assemblages from these sediments was analyzed to elucidate the transition from fresh to chemically altered materials. These data were used to evaluate the intensity of chemical weathering and its implications for erosion across contrasting lithological and climatic gradients in the Chemoga watershed of the Upper Blue Nile Basin, Ethiopia. Our findings show depletion of Na+, Ca2+, Mg2+, and K+, and enrichment of Al3+, Fe3+, Ti4+, and Mn2+ in the regolith/soil, upper part of surficial sediment, and upper layer of the core sediment (10 m). Chemical Index of Alteration (CIA) values are rocks 35–47, regolith/soil 75–96, surficial river sediments 45–96, and core sediments 50–90. River sediments in the highland area are dominated by kaolinite (39%), illite (34%), and chlorite (27%), while the lower study area has illite (76%), chlorite (11%), and kaolinite (12%). Geochemistry, ternary plots, and clay mineralogy show that the highland region underwent intensive chemical weathering, while the midland experienced intermediate to high weathering, and the lowland had weak weathering. The highlands experience severe weathering due to a humid, bimodal precipitation climate; despite having younger, weathering-resistant rocks (basalt, andesite, trachyte), the lower regions consist of older, more mafic rocks (basalt and trachybasalt). Like the surficial river sediment, core sediment showed intense chemical weathering and kaolinite dominance in the upper layers (0–10 m depth, CIA > 80). Weathering intensity decreased with depth, suggesting changes in weathering and in clay mineral formation that reflect past climate. The high weathering gradient from highland to lowland correlates with erosion, indicating that weathering strongly influences soil erosion variability in the watershed. This work provides a reasonable basis for improving our understanding of the degree of weathering across contrasting environments and its implications for soil erosion by connecting the relationship between parent materials and chemically altered samples with the degree of soil erosion. en-copyright= kn-copyright= en-aut-name=KehaliAlebachew Tareke en-aut-sei=Kehali en-aut-mei=Alebachew Tareke 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=HaregeweynNigussie en-aut-sei=Haregeweyn en-aut-mei=Nigussie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuboMitsuru en-aut-sei=Tsubo en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AntenehZelalem Leyew en-aut-sei=Anteneh en-aut-mei=Zelalem Leyew kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AyalewBelay Tesfa en-aut-sei=Ayalew en-aut-mei=Belay Tesfa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TerefeZena Tessema en-aut-sei=Terefe en-aut-mei=Zena Tessema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BelayAshebir Sewale en-aut-sei=Belay en-aut-mei=Ashebir Sewale kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FentaAyele Almaw en-aut-sei=Fenta en-aut-mei=Ayele Almaw kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsunekawaAtsushi en-aut-sei=Tsunekawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=The United Graduate School of Agricultural Sciences, Tottori University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=International Platform for Dryland Research and Education, Tottori University kn-affil= affil-num=4 en-affil=International Platform for Dryland Research and Education, Tottori University kn-affil= affil-num=5 en-affil=Department of Geology, School of Earth Sciences, Bahir Dar University kn-affil= affil-num=6 en-affil=Department of Geology, School of Earth Sciences, Bahir Dar University kn-affil= affil-num=7 en-affil=The United Graduate School of Agricultural Sciences, Tottori University kn-affil= affil-num=8 en-affil=Department of Geology, School of Earth Sciences, Bahir Dar University kn-affil= affil-num=9 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=10 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Geochemistry kn-keyword=Geochemistry en-keyword=Clay mineralogy kn-keyword=Clay mineralogy en-keyword=Core sediment kn-keyword=Core sediment en-keyword=Chemical Index of Alteration kn-keyword=Chemical Index of Alteration en-keyword=Climate kn-keyword=Climate END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=2 article-no= start-page=118 end-page=129 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Factors promoting students’ application of health checkup reports: analysis using health literacy skills framework kn-title=中・高・大学生の健診結果活用の促進要因—ヘルスリテラシースキルフレームワークを用いた検討— en-subtitle= kn-subtitle= en-abstract=Objective: This study aimed to clarify the factors associated with the application of health checkup reports and their interrelationships using a health literacy skills framework.
Methods: An anonymous, self-administered questionnaire survey was administered 493 middle school, 360 high school and 297 first-year university students. The contents included “Application of Health Checkup Reports,” “Health Interest,” “Health Literacy (HL),” “Readability of The Health Checkup Report,” “Reading Comprehension of The Report,” and “Decision-making Balance.” The hypothetical model was tested using a multi group simultaneous path analysis by school type and sex.
Results: The revised model, in which four additional paths were added, showed a good fit across all school types and sex. The paths from “Readability” to “Reading comprehension,” “Reading comprehension” to “Decision-making,” “Decision-making” to “Application,” “Health Interest” to “Reading comprehension,” “Decision-making,” and “Application,” “HL” to “Application” were significant across all school types. Conversely, the paths from “Health Interest” and “Readability” to “HL,” and “HL” to “Reading comprehension” and “Decision-making,” were significant only among middle and high school students.
Conclusion: Making the results easier to understand, enhancing reading comprehension and recognition of the pros of health checkups, and reducing recognition of the cons might effectively promote the application of health checkup reports among students. kn-abstract=目的：学校健康診断結果活用（以下，活用）と関連要因及び相互の関連性をヘルスリテラシースキルフレームワークを用いて明らかにすることを目的とした．

P. gulae fimbriae are classified into three genotypes (A, B, and C) based on the fimbrillin (fimA) gene encoding a fimbrial subunit protein. We previously reported that P. gulae organisms with type C fimbriae were clearly more virulent as compared to those with other fimbria types, though the basic function of this is not fully understood. Here, we investigated the function of fimbriae using fimA-deficient mutants. In the present study, bacterial fimbriae were related to biofilm tenacity, whereas biofilm formation was not. Also, P. gulae fimbriae are involved in bacterial adhesion and entry into gingival epithelial cells. The role of P. gulae fimbriae in bacterial pathogenicity was then determined using fimA-deficient mutants with a silkworm infection model. Additionally, P. gulae infection can induce inflammatory responses in gingival epithelial cells and also inhibit cell migration and proliferation. In contrast, a P. gulae fimA-deficient mutant did not cause several of those cellular responses. Together, the results show that fimbriae contribute to the pathogenicity of P. gulae by affecting bacterial functions and host cell interactions. en-copyright= kn-copyright= en-aut-name=InabaHiroaki en-aut-sei=Inaba en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaSho en-aut-sei=Yoshida en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NomuraRyota en-aut-sei=Nomura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoKazuhiko en-aut-sei=Nakano en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Matsumoto-NakanoMichiyo en-aut-sei=Matsumoto-Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=6 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=biofilm kn-keyword=biofilm en-keyword=cell invasion kn-keyword=cell invasion en-keyword=cell migration kn-keyword=cell migration en-keyword=fimbriae kn-keyword=fimbriae en-keyword=periodontitis kn-keyword=periodontitis en-keyword=Porphyromonas gulae kn-keyword=Porphyromonas gulae en-keyword=silkworm larvae kn-keyword=silkworm larvae END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=3 article-no= start-page=110 end-page=112 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Efficient Synthesis of Limipterin [2'-O-(2-Acetamido-2-deoxy-β- D-glucopyranosyl) -L- biopterin] via N2 - (N ,N -Dimethylamino )-methylene- 3-[2-(4-nitrophenyl)ethyl]-L-biopterin en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YamamotoHiroshi en-aut-sei=Yamamoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanayaTadashi en-aut-sei=Hanaya en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaKoichiro en-aut-sei=Harada en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawamotoHeizan en-aut-sei=Kawamoto en-aut-mei=Heizan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PfleidererWolfgang en-aut-sei=Pfleiderer en-aut-mei=Wolfgang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University 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= affil-num=5 en-affil=Universitat Konstanz, Fakultat fur Chemie kn-affil= END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=9 article-no= start-page=e70259 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Marine flatworms as windows into the evolution of bilaterian neuropeptide signalling en-subtitle= kn-subtitle= en-abstract= kn-abstract=The evolutionary origin(s) of neuropeptide signalling is still largely unknown. It has been hypothesised that signal transmission via neuropeptides played a crucial role in the regulation of nervous systems in the bilaterian ancestor. Identification, expression and functional analyses of neuropeptides and their receptors across different taxonomic groups are important for better understanding the origin(s) of bilaterian neuropeptide signalling. An example is flatworms belonging to the Platyhelminthes (spiralian protostomes) and Xenacoelomorpha (sister to all Bilateria or sister to Ambulacraria). Despite their simple morphology (i.e., a body plan lacking a coelom and circulatory system), they often possess brain-like central nervous systems and a number of bilaterian-conserved neuropeptides. This feature makes them useful models for analyses of neuropeptides and their links to nervous systems. Although previous studies have revealed orthologous relationships between vertebrate neuropeptides and those found in both marine Platyhelminthes and Xenacoelomorpha, our work suggests possible ancestral functions of vasopressin/oxytocin (VP/OT) peptides (platytocin) in these groups. en-copyright= kn-copyright= en-aut-name=NakamuraRyo en-aut-sei=Nakamura en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BaillyXavier en-aut-sei=Bailly en-aut-mei=Xavier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Multicellular Marine Models Team, CNRS – Sorbonne University – Station Biologique de Roscoff kn-affil= affil-num=4 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= en-keyword=Neuropeptide kn-keyword=Neuropeptide en-keyword=Nervous system evolution kn-keyword=Nervous system evolution en-keyword=Platyhelminthes kn-keyword=Platyhelminthes en-keyword=Xenacoelomorpha kn-keyword=Xenacoelomorpha END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=3 article-no= start-page=26 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Antioxidant Activity of α-Tocopherol Metabolites in Comparison with the Parent Compound in Hepatocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=α-Tocopherol (αT) is the major form of vitamin E. Although it is metabolized in the liver when high levels of αT are present, the function of its metabolites has not yet been fully elucidated. This study aimed to evaluate the antioxidant activities of the αT metabolites, α-carboxyethyl hydroxychroman (αCEHC) and α-carboxymethylbutyl hydroxychroman (αCMBHC), in comparison with their parent compound. The pretreatment with αT and its metabolites showed a cytoprotective effect on the cytotoxicity induced by hydrogen peroxide in the mouse hepatoma Hepa1c1c7 cells. To elucidate the mechanism underlying the effect, in vitro assays and assessments of antioxidant-related genes and proteins were conducted. The in vitro assays showed that these compounds showed little scavenging activity against hydrogen peroxide but exhibited scavenging activity against DPPH radicals. On the other hand, assessments of antioxidant-related genes and proteins showed that αT and its metabolites significantly upregulated the expression of heme oxygenase-1 (HO-1) possibly through activation of the transcript factor Nrf2. Moreover, the cytoprotective effects of αT and its metabolites against hydrogen peroxide were counteracted by HO-1 inhibitors. These results suggest that not only αT but also its metabolites are potential cytoprotective factors against oxidative stress-induced cytotoxicity, and that their effects are exerted not through a direct action of scavenging hydrogen peroxide in the body, but rather through the regulation of gene expression. en-copyright= kn-copyright= en-aut-name=NishioTomoka en-aut-sei=Nishio en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AmakoKasumi en-aut-sei=Amako en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyaDaiki en-aut-sei=Moriya en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=α-tocopherol kn-keyword=α-tocopherol en-keyword=α-carboxyethyl hydroxychroman kn-keyword=α-carboxyethyl hydroxychroman en-keyword=α-carboxymethylbutyl hydroxychroman kn-keyword=α-carboxymethylbutyl hydroxychroman en-keyword=metabolite kn-keyword=metabolite en-keyword=antioxidant activity kn-keyword=antioxidant activity END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=7 article-no= start-page=103553 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Patient-centred communication in radiographer education: A five-country comparative document analysis of curriculum and competency standards en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Patient-centred communication is fundamental to radiographic practice, particularly when patients experience anxiety or uncertainty during imaging or treatment. However, it remains unclear whether broad communication expectations in radiography education and professional standards are translated into explicit, observable behaviours and integrated into education and assessment. This comparative document analysis examined the representation of patient-centred communication in selected national-level documents from five countries, using listening-related behaviours as an illustrative example.
Methods: Selected national-level curriculum, accreditation, registration, capability, and competency documents from the United States, the United Kingdom, Australia, Canada, and Japan were analysed deductively using a predefined extraction framework. The framework assessed communication competence, listening-related behaviours, patient-centred care, patient/family relationships, interprofessional collaboration, education, and assessment.
Results: Communication was addressed in all five selected national-level document sets, although institutional framing differed. It was framed as a professional competency or capability in the United Kingdom and Australia, a role-based competency framework in Canada, clinical competency and accreditation requirements in the United States, and primarily as curriculum content in Japan. Explicit observable behavioural expectations, such as listening-related behaviours, were uncommon. Listening was explicitly defined only in the Australian capability standards; elsewhere, it was represented indirectly through broader concepts, such as patient interaction, information gathering, and interpersonal communication.
Conclusion: The selected documents differed in the explicitness, structure, and educational integration of communication-related standards, without implying differences in education quality or clinical outcomes. Defining patient-centred communication through observable behaviours may strengthen alignment among professional expectations, learning outcomes, feedback, and assessment.
Implications for practice: Operationalising patient-centred communication as observable behaviours may enhance curriculum mapping, feedback, and assessment in radiographer education. en-copyright= kn-copyright= en-aut-name=KomatsuY. en-aut-sei=Komatsu en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChikamotoY. en-aut-sei=Chikamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukanoK. en-aut-sei=Tsukano en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeS. en-aut-sei=Abe en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsudouS. en-aut-sei=Tsudou en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoY. en-aut-sei=Yamamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanabeY. en-aut-sei=Tanabe en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Independent Researcher kn-affil= affil-num=3 en-affil=Department of Psychosomatic Medicine, Yokohama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=Radiographer education kn-keyword=Radiographer education en-keyword=Patient-centred communication kn-keyword=Patient-centred communication en-keyword=Listening kn-keyword=Listening en-keyword=Competency standards kn-keyword=Competency standards en-keyword=Curriculum standards kn-keyword=Curriculum standards en-keyword=Document analysis kn-keyword=Document analysis END start-ver=1.4 cd-journal=joma no-vol=139 cd-vols= no-issue=2 article-no= start-page=255 end-page=265 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knockout of a single aquaporin, OsPIP2;4, decreases root water permeability in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aquaporins (AQPs) are membrane proteins that facilitate water transport and are present in nearly all bacterial, animal, and plant cells. In plants, AQPs are classified into four or more subfamilies, with plasma membrane intrinsic proteins (PIPs) playing a key role in root water uptake and cellular water regulation. Previous studies have demonstrated that PIPs contribute to root hydraulic conductivity (Lpr) in various plant species. In this study, we examined the specific role of OsPIP2;4, one of the PIP-type aquaporins among 11 rice (Oryza sativa) PIP2s, in regulating Lpr. Transgenic rice plants, including OsPIP2;4-knockout (KO) and overexpressing (Ox) lines, were used for this investigation. Two independent KO lines, generated via the CRISPR-Cas9 system and T-DNA insertion mutagenesis, respectively, showed significantly lower Lpr compared to wild-type rice plants. The decrease in Lpr in the T-DNA KO line was associated with reduced OsPIP2;4 transcript levels, measured by real-time PCR, and lower OsPIP2;4 protein levels, as shown by immunohistochemical analysis. Conversely, no notable increase in Lpr was observed in the Ox lines. These results suggest that OsPIP2;4 is expressed in appropriate tissues in rice roots and is a key factor influencing Lpr. This research represents a significant step toward further understanding the physiological functions of OsPIP2;4 in rice. en-copyright= kn-copyright= en-aut-name=OnishiAya en-aut-sei=Onishi

kn-abstract=　障がい者の文化芸術活動では，障がい者が創造や発信に主体的に関わることが重視されている。しかし，その一形態であるインクルーシブダンスを地域社会に開かれた文化活動へと展開する事例の分析は十分ではない。そこで本稿では，岡山県の「うらじゃ」祭りにおいて発足したインクルーシブ踊り連「一期一会〜輪舞温羅」を対象に，インクルーシブうらじゃダンスの開発および実践過程を整理した。活動記録，映像記録，活動資料をもとに分析した結果，表現内容や実施方法，演舞環境が，参加者の心身の特性を踏まえて段階的に調整されていたことが明らかとなった。また，参加者の主観的運動強度は主に「楽」から「ややきつい」の範囲に分布し，活動満足度も高い傾向を示した。以上より，本プロジェクトは，地域文化を基盤としたインクルーシブな身体表現活動に関する基礎的知見を提供するものであると考えられる。

kn-abstract=　近代日本における西洋教育の日本教育への影響を考察し，とくに世界で伝播のあったモニトリアル・システム（助教法）の日本教育における位置を検討する。19世紀後半は，近世の寺子屋の時代から近代の小学校の時代への転換期であった。国民教育の場としての小学校が整い，男女が就学する状況の形成があった。この過程において，日本がアメリカ経由で受容した一斉教授は，教師が教室で教授する方法であった。助教を用いる方法ではなかった。本稿は，近代日本ではモニトリアル･システムを基本的には経験しない展開と，一斉教授を行う教師の養成があったことを論じるものである。

Also, we demonstrated a strategy to develop regioselective C–H activation by optimizing externalDG depending on the substrate. The means for optimizing externalDG include the selection of the precursor, the addition of a Lewis acid, and changing the ratio of the precursor/Pd, to control the reactivity and regioselectivity. en-copyright= kn-copyright= en-aut-name=YanoKoki en-aut-sei=Yano en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaDaisuke en-aut-sei=Sawada en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=6 article-no= start-page=e202500237 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=NUAK2 Inhibition Enhances Macromolecular Drug Delivery in a 3D Fibrotic Model of the Pancreatic Tumor Microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic ductal adenocarcinoma (PDAC) features a fibrotic tumor microenvironment that impedes drug delivery and significantly limits the successful clinical application of nanomedicines. Targeting signaling in pancreatic stellate cells (PSCs), which drive fibrosis via excessive secretion of extracellular matrix proteins such as collagen I, may be useful in overcoming this fibrotic barrier. The AMPK-related kinases NUAK1/2 have recently gained interest as promoters of fibrosis, but whether they play a profibrotic role in PSCs remains unknown. Here, patient PSCs are used to assess NUAK1/2 involvement in the PDAC fibrotic barrier. Leveraging a 3D cell culture model of PDAC fibrosis, the effect of targeting NUAK1/2 on the permeability of macromolecular dextrans of various sizes, as well as physiologically relevant macromolecules, albumin and IgG, and clinical nanomedicines, Doxil and Abraxane, is investigated. NUAK1/2 inhibition is shown to diminish collagen I to enhance macromolecular permeability, via a mechanism independent of established pathways involving transforming growth factor-β (TGFβ) and yes-associated protein (YAP). Through isoform-specific knockdown, predominant NUAK2 involvement is demonstrated. Mechanistically, actin stress fiber regulation by NUAK2 is shown to be important. Altogether, these results show in vitro that NUAK2 promotes fibrotic signaling in PSCs and may be targeted to enhance macromolecular drug delivery in PDAC. en-copyright= kn-copyright=

kn-title=AHG1–AFP interaction as a regulatory node in the ABA response during seed germination en-subtitle= kn-subtitle= en-abstract= kn-abstract=Seed dormancy and germination are tightly regulated by complex signaling networks that integrate internal and external cues, including the endogenous phytohormone abscisic acid (ABA). ABA HYPERSENSITIVE GERMINATION 1 (AHG1), a group A type 2C protein phosphatase (PP2C), is thought to modulate the activity of transcription factors such as ABA INSENSITIVE 5 (ABI5) in seeds and during germination. AHG1 is regulated by DELAY OF GERMINATION 1 (DOG1), a key regulator of seed dormancy, through physical interaction. We previously reported that AHG1 also interacts with ABI FIVE BINDING PROTEIN 2 (AFP2), a member of the AFP family; however, the molecular basis of AHG1–AFP coordination has remained unclear. In this study, we show that AHG1 interacts with all AFP family members and that AFP3 binds AHG1 and ABI5 through adjacent but distinct amino acid residues within its C-domain, allowing simultaneous association with both proteins. In addition, AHG1 modulates the phosphorylation status of AFP3 at Ser60 in a DOG1-dependent manner, suggesting that DOG1–AHG1 regulates AFP3 post-translationally. Transcriptomic analyses of AHG1- or AFP3-overexpressing lines revealed that these factors are associated with the regulation of a shared set of ABA-responsive genes, including AFPs, and that AFP3 overexpression is predominantly associated with altered expression of genes involved in transcriptional regulation. Large-scale protein interaction analyses showed that AFPs interact with multiple classes of transcription factors, suggesting their involvement in diverse regulatory pathways, including ABA signaling. Together, these findings demonstrate that DOG1 regulates ABI5 function and modulates ABA responses, at least in part, by controlling AHG1-mediated dephosphorylation of AFPs. en-copyright= kn-copyright= en-aut-name=NishimuraNoriyuki en-aut-sei=Nishimura en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshiyamaSho en-aut-sei=Ushiyama en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtagiriMasato en-aut-sei=Otagiri en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatohKouji en-aut-sei=Satoh en-aut-mei=Kouji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiNahomi en-aut-sei=Suzuki en-aut-mei=Nahomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IrisaTomoko en-aut-sei=Irisa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MitsudaNobutaka en-aut-sei=Mitsuda en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmezawaTaishi en-aut-sei=Umezawa en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishimuraHideki en-aut-sei=Nishimura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NemotoKeiichirou en-aut-sei=Nemoto en-aut-mei=Keiichirou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsuchiyaWataru en-aut-sei=Tsuchiya en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YanoRyoichi en-aut-sei=Yano en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SawasakiTatsuya en-aut-sei=Sawasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YamazakiToshimasa en-aut-sei=Yamazaki en-aut-mei=Toshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Institute of Agrobiological Sciences, National Agriculture and Food Research Organization 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=Institute of Agrobiological Sciences, National Agriculture and Food Research Organization kn-affil= affil-num=5 en-affil=Institute of Agrobiological Sciences, National Agriculture and Food Research Organization kn-affil= affil-num=6 en-affil=Institute of Agrobiological Sciences, National Agriculture and Food Research Organization kn-affil= affil-num=7 en-affil=Biomanufacturing Process Research Center, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=8 en-affil=Graduate School of Advanced Interdisciplinary Science, Tokyo University of Agriculture and Technology kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=10 en-affil=Proteo-Science Center, PIAS, Ehime University kn-affil= affil-num=11 en-affil=Research Center for Advanced Analysis, National Agriculture and Food Research Organization kn-affil= affil-num=12 en-affil=Research Center for Advanced Analysis, National Agriculture and Food Research Organization kn-affil= affil-num=13 en-affil=Proteo-Science Center, PIAS, Ehime University kn-affil= affil-num=14 en-affil=Research Center for Advanced Analysis National Agriculture and Food Research Organization Tsukuba Ibaraki 305‐8518 Japan kn-affil= affil-num=15 en-affil=Research Center for Advanced Analysis, National Agriculture and Food Research Organization kn-affil= en-keyword=ABA kn-keyword=ABA en-keyword=AHG1 kn-keyword=AHG1 en-keyword=AFP kn-keyword=AFP en-keyword=ABI5 kn-keyword=ABI5 en-keyword=DOG1 kn-keyword=DOG1 en-keyword=seed dormancy kn-keyword=seed dormancy en-keyword=seed germination kn-keyword=seed germination en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=13 article-no= start-page=4866 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changing Trends in Cardiovascular Disease Burden in North Africa and the Middle East, 1990–2023: A Joinpoint Analysis of GBD 2023 Data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Cardiovascular disease (CVD) burden decreased in the North Africa and Middle East (NAME) region between 1990 and 2019. This study used Global Burden of Disease (GBD) 2023 data to examine whether trends in mortality, disability-adjusted life years (DALYs), incidence, and prevalence continued through 2023 across all 21 NAME countries. Methods: We analysed age-standardised CVD mortality, incidence, prevalence, and DALY rates from 1990 to 2023. Joinpoint regression identified changes in temporal trends and calculated the annual percent change (APC) and average annual percent change (AAPC) with 95% confidence intervals (CIs). Results: Age-standardised CVD mortality decreased from 579.6 per 100,000 in 1990 to 358.2 in 2023 (AAPC: −1.42%; 95% CI: −1.48 to −1.35). However, no significant reduction occurred between 2019 and 2023 (APC: −0.33%; 95% CI: −1.37 to 1.75). DALY, incidence, and prevalence rates followed similar patterns, with no significant decline in the final years of this study. Egypt was the only country with a long-term increase in CVD mortality, which accelerated after 2020 (APC: +5.20%; 95% CI: 1.20 to 12.87). High systolic blood pressure, dietary risks, lead exposure, and air pollution were the leading modifiable risk factors. Conclusions: The earlier decline in CVD burden in the NAME region did not clearly continue after 2019. The region is currently off track to meet Sustainable Development Goal 3.4 by 2030. Future progress may depend on improved blood pressure control, lipid management, dietary habits, and environmental risk reduction. en-copyright= kn-copyright= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LescanoJudah Israel Ong en-aut-sei=Lescano en-aut-mei=Judah Israel Ong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwataNaohiro en-aut-sei=Iwata en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Hematology and Oncology, Mayo Clinic kn-affil= affil-num=5 en-affil=Division of Hematology and Oncology, Mayo Clinic kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cardiovascular diseases kn-keyword=cardiovascular diseases en-keyword=global burden of disease kn-keyword=global burden of disease en-keyword=North Africa and Middle East kn-keyword=North Africa and Middle East en-keyword=risk factors kn-keyword=risk factors en-keyword=joinpoint regression kn-keyword=joinpoint regression END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=7 article-no= start-page=1352 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diabetes Burden in the Middle East and North Africa Region, 1990–2023: An Ecological Time-Trend Analysis of GBD Estimates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objectives: The Middle East and North Africa (MENA) region has one of the highest age-standardized diabetes prevalence rates globally, yet all-age, diabetes-specific evidence incorporating GBD 2023 estimates through 2023 remains limited. Materials and Methods: Using Global Burden of Disease (GBD) 2023 estimates for 21 MENA countries from 1990 to 2023, this ecological time-trend analysis quantified 33-year trends in incidence, prevalence, mortality, and disability-adjusted life-years (DALYs); compared pre-2019 and post-2019 trajectories using joinpoint regression; characterized age- and sex-specific burden patterns; and quantified contributions of modifiable risk factors. Results: Age-standardized incidence increased 92%, from 251.7 (95% uncertainty interval [UI]: 231.5 to 272.4) to 482.5 (95% UI: 451.5 to 516.4) per 100,000, and prevalence more than doubled, from 5564 (95% UI: 5088 to 6024) to 11,247 (95% UI: 10,382 to 12,132) per 100,000. In 2023, males exhibited higher DALY rates than females in most adult age groups from age 15 years onward, shifting away from the female-predominant pattern seen in 1990; female rates remained higher at several of the oldest age groups. Children aged 0 to 14 years were the only group with declining DALY rates (−52% to −57%). Post-2019 incidence was higher in 15 of 21 countries, and six countries had higher DALY trends with non-overlapping confidence intervals. Because we only have four to five years of data, these short trends are preliminary and require care when evaluating. High body-mass index was the leading modifiable risk factor. Conclusions: These data support country-specific prevention and chronic-care strategies across the MENA region. en-copyright= kn-copyright= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LescanoJudah Israel Ong en-aut-sei=Lescano en-aut-mei=Judah Israel Ong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwataNaohiro en-aut-sei=Iwata en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HigashionnaTsukasa en-aut-sei=Higashionna en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Hematology and Oncology, Mayo Clinic kn-affil= affil-num=5 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Faculty of Pharmacy, Haiphong University of Medicine and Pharmacy kn-affil= affil-num=8 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=GBD 2023 kn-keyword=GBD 2023 en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=Middle East and North Africa kn-keyword=Middle East and North Africa en-keyword=joinpoint regression kn-keyword=joinpoint regression en-keyword=cardiovascular risk factors kn-keyword=cardiovascular risk factors en-keyword=epidemiology kn-keyword=epidemiology en-keyword=public health kn-keyword=public health 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=2026 dt-pub=20260820 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Performance of generative artificial intelligence in oral and maxillofacial radiology based on the board-certification examination of Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective To evaluate the performance and potential utility of generative artificial intelligence (AI) in oral and maxillofacial radiology using the board-certification examination administered by the Japanese Society for Oral and Maxillofacial Radiology (JSOMR).
Methods The responses generated by ChatGPT for multiple-choice questions from the board-certification examination of the JSOMR over the three-year period from 2020 to 2022 were assessed. The questions were manually entered individually as prompts for GPT-3.5, GPT-4, and GPT-5, which are the models available from ChatGPT. The accuracy was calculated according to examination year, question format, and level of taxonomy.
Results GPT-3.5 achieved an accuracy of 40.3% for the three years (42.9%, 42.0%, and 36.0% for 2020, 2021, and 2022, respectively), that of GPT-4 was 67.8% (67.3%, 74.0%, and 62.0%, respectively), and that of GPT-5 was 76.5% (79.6%, 78.0%, and 72.0%, respectively). GPT-5’s results exceeded the passing score for each year with the accuracy significantly outperformed that of GPT-3.5 and GPT-4. Regarding performance according to the question format, GPT-5 performed significantly superior to the earlier models, especially on two-answer questions.
Conclusions On the board-certification examination of the JSOMR, the performance of GPT-5 was significantly superior to that of GPT-3.5 and GPT-4. This suggests that, given the rapid development of generative AI, GPT-5 has reached a level of text-based knowledge equivalent to that assessed in the board-certification examination of the JSOMR. en-copyright= kn-copyright= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawazuToshiyuki en-aut-sei=Kawazu en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HisatomiMiki en-aut-sei=Hisatomi en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujikuraMamiko en-aut-sei=Fujikura en-aut-mei=Mamiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibanumaAkira en-aut-sei=Shibanuma en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NambaYuri en-aut-sei=Namba en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaSuzuka en-aut-sei=Yoshida en-aut-mei=Suzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakamuraYoshihide en-aut-sei=Nakamura en-aut-mei=Yoshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YanagiYoshinobu en-aut-sei=Yanagi en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=6 en-affil=Department of Community and Global Health, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Radiology, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=9 en-affil=Preliminary Examination Room, Medical Development Field, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Artificial intelligence kn-keyword=Artificial intelligence en-keyword=Generative artificial intelligence kn-keyword=Generative artificial intelligence en-keyword=ChatGPT kn-keyword=ChatGPT en-keyword=Large language model kn-keyword=Large language model en-keyword=Radiology kn-keyword=Radiology en-keyword=Education kn-keyword=Education END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=2 article-no= start-page=122 end-page=129 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=RHOA G17V mutation analysis redirecting diagnosis: nodal T-follicular helper cell lymphoma with classic Hodgkin lymphoma feature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nodal T-follicular helper cell lymphoma (nTFHL) may present with Hodgkin/Reed–Sternberg (HRS)-like cells and can morphologically mimic classic Hodgkin lymphoma (CHL), although these entities are usually distinguishable. We report an unusual case showing marked morphologic and molecular overlap with CHL, creating a diagnostic challenge but ultimately considered biologically consistent with nTFHL.
An 81-year-old woman presented with stage IV disease involving the bone marrow and markedly elevated serum soluble interleukin-2 receptor levels. Excisional lymph node biopsy revealed scattered HRS cells in a T-cell–rich background, with strong CD30 and PD-L1 expression and weak PAX5 positivity, findings consistent with CHL. Fluorescence in situ hybridization demonstrated copy-number alterations at the 9p24.1 locus in HRS cells, further supporting molecular features characteristic of CHL.
However, the presence of two T-follicular helper markers, detection of the RHOA p.Gly17Val (G17V) mutation, and oligoclonal T-cell receptor rearrangements with shared peaks in lymph node and bone marrow indicated an underlying nTFHL. The differential therapeutic response also supported a diagnosis of nTFHL, which could not have been established on morphology alone.
In this case, although the HRS cells displayed morphological, immunophenotypic, and molecular features highly suggestive of CHL, the biological nature of the lesion was consistent with nTFHL. Compared with previously reported cases of nTFHL with HRS-like cells, this case more closely resembled CHL and may represent a distinct subset best described as “nTFHL with CHL features,” a concept warranting greater recognition among pathologists and clinicians. en-copyright= kn-copyright= en-aut-name=YamadaRio en-aut-sei=Yamada en-aut-mei=Rio 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=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukumiTakuya en-aut-sei=Fukumi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhsawaKumiko en-aut-sei=Ohsawa en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MomoseShuji en-aut-sei=Momose en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health 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 Hematology, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Saitama Medical Center, Saitama Medical University kn-affil= affil-num=6 en-affil=Department of Pathology, Saitama Medical Center, Saitama Medical University kn-affil= affil-num=7 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=classic Hodgkin lymphoma kn-keyword=classic Hodgkin lymphoma en-keyword=nodal T-follicular helper cell lymphoma kn-keyword=nodal T-follicular helper cell lymphoma en-keyword=RHOA mutation kn-keyword=RHOA mutation END start-ver=1.4 cd-journal=joma no-vol=229 cd-vols= no-issue= article-no= start-page=105080 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced calcium activity and transcriptomic alterations in iPSC-derived neurons from BAFME patients with repeat expansions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Benign adult familial myoclonus epilepsy (BAFME) is caused by intronic TTTCA and TTTTA repeat expansions in SAMD12 and other genes; the neuronal basis of cortical hyperexcitability, however, remains unclear. We generated induced pluripotent stem cell (iPSC)-derived glutamatergic and GABAergic neurons from three BAFME1 patients and examined functional and transcriptomic phenotypes. Patient-derived neurons retained the pathogenic repeat expansions and showed a tendency toward upstream intronic RNA accumulation. Calcium imaging revealed increased spontaneous Ca2 + transient frequency in both neuronal subtypes, indicating heightened activity. Pharmacological profiling demonstrated attenuated responses to calcium-permeable α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptor (CP-AMPAR) blockade and GABAA receptor antagonism in GABAergic neurons, suggesting altered inhibitory signaling. RNA sequencing revealed transcriptomic alterations without differential expression of ion channels and neurotransmitter receptors. In glutamatergic neurons, ATF4-regulated genes, including SLC7A5 encoding LAT1, a Kv1.2 channel modulator, were downregulated. Reduced SLC7A5 expression was validated at both mRNA and protein levels. In GABAergic neurons, synapse-associated genes PTPRD and GPC6 were upregulated. TCERG1L and NLRP2 were suppressed across both neuronal subtypes. These findings suggest subtype-specific alterations may contribute to neuronal hyperexcitability in BAFME and provide a platform for mechanistic studies of repeat expansion-associated epilepsies. en-copyright= kn-copyright= en-aut-name=NagasakoYuki en-aut-sei=Nagasako en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaMitsuru en-aut-sei=Ishikawa en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SupakulSopak en-aut-sei=Supakul en-aut-mei=Sopak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaSumihiro en-aut-sei=Maeda en-aut-mei=Sumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TodaTatsushi en-aut-sei=Toda en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsujiShoji en-aut-sei=Tsuji en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkanoHideyuki en-aut-sei=Okano en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=2 en-affil=Department of Physiology, Keio University School of Medicine 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 Physiology, Keio University School of Medicine kn-affil= affil-num=5 en-affil=Department of Physiology, Keio University School of Medicine kn-affil= affil-num=6 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=8 en-affil=Department of Physiology, Keio University School of Medicine kn-affil= en-keyword=Induced pluripotent stem cells kn-keyword=Induced pluripotent stem cells en-keyword=Glutamatergic neurons kn-keyword=Glutamatergic neurons en-keyword=GABAergic neurons kn-keyword=GABAergic neurons en-keyword=Calcium imaging kn-keyword=Calcium imaging en-keyword=BAFME kn-keyword=BAFME en-keyword=Repeat expansion kn-keyword=Repeat expansion en-keyword=Epilepsy kn-keyword=Epilepsy END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue= article-no= start-page=100152 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immersion is not enough: Design quality as the key determinant of perceived effectiveness and usage intention in educational virtual reality en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immersive technologies such as Virtual Reality (VR) are increasingly used to support conceptual understanding in science education, yet perceived learning benefits depend on the quality of system design rather than immersion alone. This study investigates how four design-quality dimensions—Visual and Technological Design (VT), Aesthetic Quality (AQ), Curriculum Alignment (CA), and Digital Feasibility (DF)—influence learners' Perceived Effectiveness (PE) and Intention to Use (IU) the VARIASI VR simulation, which visualizes particle behavior across phase states of matter. Using an explanatory sequential mixed-methods design, quantitative data from 60 participants were analyzed using PLS-SEM, followed by reflexive thematic analysis of open-ended responses. Results show that VT, AQ, CA, and DF each significantly predict PE, demonstrating that learners' perception of effectiveness depends on the coordinated alignment of conceptual clarity, emotional resonance, and system reliability. However, none of these dimensions directly predicted IU, and the PE → IU relationship was positive but marginal, reflecting learners’ need for procedural guidance and comfort to sustain voluntary adoption. Qualitative findings reveal that while VR enhanced conceptual clarity and engagement, continued use depended on familiarity, scaffolding, and physical comfort. The study highlights that effective VR-based science learning experiences emerge when immersive environments are not only well-designed but pedagogically framed to support confidence and sustained use. en-copyright= kn-copyright= en-aut-name=SamsudinAchmad en-aut-sei=Samsudin en-aut-mei=Achmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZahranMuhammad en-aut-sei=Zahran en-aut-mei=Muhammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NugrahaEki en-aut-sei=Nugraha en-aut-mei=Eki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NasbeyHadi en-aut-sei=Nasbey en-aut-mei=Hadi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SozbilirMustafa en-aut-sei=Sozbilir en-aut-mei=Mustafa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RahmanNor Farahwahidah Abdul en-aut-sei=Rahman en-aut-mei=Nor Farahwahidah Abdul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IrieTakashi en-aut-sei=Irie en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Universitas Pendidikan Indonesia kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Universitas Pendidikan Indonesia kn-affil= affil-num=4 en-affil=Universitas Negeri Jakarta kn-affil= affil-num=5 en-affil=Atatürk University kn-affil= affil-num=6 en-affil=Universiti Teknologi Malaysia kn-affil= affil-num=7 en-affil=Okayama University kn-affil= en-keyword=Virtual reality kn-keyword=Virtual reality en-keyword=Science education kn-keyword=Science education en-keyword=Immersive learning kn-keyword=Immersive learning en-keyword=Design quality kn-keyword=Design quality en-keyword=PLS-SEM kn-keyword=PLS-SEM en-keyword=Technology adoption kn-keyword=Technology adoption END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e02824-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Escalation of CTX-M-producing extensively drug-resistant Shigella spp. in Kolkata, India, following the COVID-19 pandemic en-subtitle= kn-subtitle= en-abstract= kn-abstract=Shigella spp. is recognized by the World Health Organization as a high-priority pathogen due to its global prevalence, unique pathogenic mechanisms, and growing antimicrobial resistance (AMR). Nearly half of all Shigella strains worldwide are now multidrug-resistant (MDR), and the emergence of extensively drug-resistant (XDR) variants—resistant to ciprofloxacin, ceftriaxone, and azithromycin—has severely limited effective treatment options. The present study is based on prospective laboratory surveillance involving 323 Shigella isolates collected during 2021–2023, with pre-COVID-19 pandemic data included from a previously published study solely for historical comparison. The presence of antibiotic resistance genes (ARGs) was investigated, and whole-genome sequencing (WGS) was performed on representative isolates to assess phylogenetic relatedness with global isolates. Approximately 10% of isolates exhibited resistance to third-generation cephalosporins. While only 3% of Shigella isolates carried the blaCTX-M-15 gene from 2013 to 2019, its prevalence increased to 26% by 2022–2023. Among 38 ceftriaxone-resistant S. sonnei isolates, 33 were also resistant to azithromycin, categorizing them as XDR. These isolates showed 48% clonal similarity and high phylogenetic resemblance to the isolates reported from England. Hybrid genome assembly revealed a plasmid harboring both the blaCTX-M-15 and mphA ARGs. Conjugation experiments and plasmid profiling confirmed the plasmid’s transferability. We report a rising trend in third-generation cephalosporin resistance among Shigella spp., primarily driven by the spread of extended-spectrum β-lactamase-producing S. flexneri and the emergence of XDR S. sonnei. These findings underscore the urgent need for strengthened national AMR containment strategies and enhanced international surveillance of cephalosporin-resistant Shigella to mitigate this growing public health threat. en-copyright= kn-copyright= en-aut-name=BosePuja en-aut-sei=Bose en-aut-mei=Puja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HalderGourab en-aut-sei=Halder en-aut-mei=Gourab kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KayetPratanu en-aut-sei=Kayet en-aut-mei=Pratanu 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=BasakSurajit en-aut-sei=Basak en-aut-mei=Surajit kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RoyDeboleena en-aut-sei=Roy en-aut-mei=Deboleena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ImamuraDaisuke en-aut-sei=Imamura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=MoritaMasatomo en-aut-sei=Morita en-aut-mei=Masatomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoleyHemanta en-aut-sei=Koley en-aut-mei=Hemanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DasSantasabuj en-aut-sei=Das en-aut-mei=Santasabuj kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MukhopadhyayAsish Kumar en-aut-sei=Mukhopadhyay en-aut-mei=Asish Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=2 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=3 en-affil=Division of Bioinformatics, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=4 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=5 en-affil=Division of Bioinformatics, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=6 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=7 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=8 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=9 en-affil=Department of Bacteriology I, National Institute of Infectious Diseases kn-affil= affil-num=10 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=11 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=12 en-affil=Division of Clinical Medicine, ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=13 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections kn-affil= en-keyword=dysentery kn-keyword=dysentery en-keyword=AMR kn-keyword=AMR en-keyword=XDR kn-keyword=XDR en-keyword=Shigella spp. kn-keyword=Shigella spp. en-keyword=CTX-M kn-keyword=CTX-M en-keyword=plasmid kn-keyword=plasmid en-keyword=transconjugants kn-keyword=transconjugants en-keyword=PFGE kn-keyword=PFGE en-keyword=WGS kn-keyword=WGS END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=1874501 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High horizontal force and lateral force transmission induced by the twist of the Achilles tendon en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Achilles tendon—the largest and strongest of the many tendons in the human body—consists of subtendons arising from each head of the triceps surae. These subtendons run helically and intertwine to form a twisted three-dimensional structure. More than a century has passed since the twisted structure of the Achilles tendon was first described, and numerous studies have investigated its functional morphology. However, it remains unclear how the presence or degree of twist affects the mechanical function of the lower limbs. Here, using finite element models of the Achilles tendon with and without twist, we show that the presence and degree of twist can modulate the forces transmitted from muscle to skeleton in a complex manner. In contrast to the model without twist, the twisted models clearly exhibit anterolaterally directed horizontal forces at the distal end under a simple proximal tensile load. The lateral and anterior components reach approximately 101 N and 63 N, respectively. Furthermore, the twisted structure induces inter-subtendon force transmission, and the magnitude of the transmitted force increases with increasing degree of twist. These results indicate that the uniaxial contractile force generated by the triceps surae is transformed into triaxial forces by the twisted Achilles tendon and is redistributed in a complex three-dimensional manner through inter-subtendon interactions. en-copyright= kn-copyright= en-aut-name=EnomotoShota en-aut-sei=Enomoto en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoKohta en-aut-sei=Ito en-aut-mei=Kohta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=2 en-affil=Artificial Intelligence Research Center, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= en-keyword=computer aided engineering kn-keyword=computer aided engineering en-keyword=finite element analysis kn-keyword=finite element analysis en-keyword=modeling kn-keyword=modeling en-keyword=morphology kn-keyword=morphology en-keyword=subtendons kn-keyword=subtendons END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=29 article-no= start-page=12214 end-page=12224 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Terpolymerization of epoxide, oxetane, and CO2 for the synthesis of polycarbonates with high CO2 contents, physical tunability, and enzymatic degradability en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although poly(cyclohexene carbonate) (PCHC) synthesized by the copolymerization of cyclohexene oxide (CHO) and CO2 is a promising material, the physical properties of this material need to be altered and tuned for its wider applications. To this end, we employed a terpolymerization strategy increasing the CO2 content in the resulting polymers. Terpolymerization of CHO, oxetane, and CO2 using AlIII porphyrin catalysts with quaternary ammonium halides afforded polycarbonates with high CO2 contents, physical tunability, and enzymatic degradability. The counter anions of the catalysts were crucial factors in the formation of the poly(trimethylene carbonate) (PTMC) unit. 1a with bromide ions preferentially produced trimethylene carbonate (TMC) over PTMC, while 1d with chloride ions suppressed the formation of TMC and produced PCHC–PTMC directly. PCHC–PTMC showed glass transition temperatures (Tg) between 69 °C and −9 °C, depending on the PCHC/PTMC ratio. The tensile test revealed that the PTMC unit contributed to the softening of the film materials. For example, a film material with a CO2 content of 38 wt% showed 505% elongation at break with an elastic character, which contrasted starkly with the 1.3% elongation at break of PCHC with a CO2 content of 31 wt%. Moreover, the selective degradation of the PTMC unit in PCHC–PTMC was achieved with lipases, and a gradient character in the sequence structure was suggested. Overall, PCHC–PTMC is an environmentally benign and sustainable CO2-based polycarbonate. en-copyright= kn-copyright= en-aut-name=NikiKaito en-aut-sei=Niki en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi 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=32 cd-vols= no-issue=6 article-no= start-page=103486 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Students’ perceptions of an electronic one-minute paper in a radiography training programme: An exploratory cross-sectional questionnaire study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Formative assessment can support health professions education; however, reports on electronic 1-min papers as classroom feedback and engagement tools in radiography programmes remain limited. This study explored radiography students’ perceptions of an electronic 1-min paper, focusing on in-class reflection, ease of asking questions, and instructor feedback.
Methods: An electronic 1-min paper was used in a radiotherapy course across 45 class sessions in the 2024 academic year for third-year students enrolled in a 4-year radiography programme. Each 90-min class comprised a 60-min lecture, 10-min completion of the paper, and 20-min instructor feedback. After the course, a de-identified online questionnaire was administered. Eleven 5-point Likert-scale items were analysed using descriptive statistics and Spearman's rank correlations. Free-text responses were analysed using inductive qualitative content analysis.
Results: Of the 77 eligible students, 74 responded (96.1%). Ease of use received the highest rating (mean, 4.76; standard deviation [SD], 0.52), followed by ease of asking questions (mean, 4.32), question resolution (mean, 4.16), and usefulness of instructor feedback (mean, 4.08). Motivation to review after class was lowest (mean, 3.04; SD, 1.16). Active participation showed a strong positive association with in-class concentration (rs = 0.815; P < 0.001). Free-text responses indicated reflection and improved understanding, anonymous sharing of questions, active listening and concentration, and suggestions for improvement.
Conclusion: The electronic 1-min paper was widely accepted and perceived to support in-class reflection, question expression, and immediate feedback. However, students’ perceptions of its influence on out-of-class review motivation were limited. The findings indicate perceived value and engagement rather than demonstrated educational effectiveness.
Implications for practice: Electronic 1-min papers may help instructors identify students’ questions and respond during class, providing a practical approach to in-class feedback. en-copyright= kn-copyright= en-aut-name=KomatsuY. en-aut-sei=Komatsu en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbeS. en-aut-sei=Abe en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsudouS. en-aut-sei=Tsudou en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoY. en-aut-sei=Yamamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeY. en-aut-sei=Tanabe en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Health Sciences, Department of Radiological Technology, Okayama University Medical School, Okayama University kn-affil= en-keyword=Electronic 1-min paper kn-keyword=Electronic 1-min paper en-keyword=Formative assessment kn-keyword=Formative assessment en-keyword=Radiography education kn-keyword=Radiography education en-keyword=Immediate feedback kn-keyword=Immediate feedback en-keyword=Student engagement kn-keyword=Student engagement en-keyword=Health professions education kn-keyword=Health professions education END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=7 article-no= start-page=455 end-page=460 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dielectric response modulation in relaxor (Sr,Ba)Nb2O6 via engineered defect en-subtitle= kn-subtitle= en-abstract= kn-abstract=Defect engineering provides an effective pathway to tune the dielectric response of relaxor ferroelectrics, yet the roles of individual defect species in tungsten bronze (TTB) systems remain unclear. Here, we investigated how engineered Ti–VO•• defect dipoles and native oxygen vacancies introduced through reduction annealing modify the dielectric properties of relaxor (Sr0.5,Ba0.5)Nb2O6 (0.5-SBN). Ti loading forms stable defect dipoles that generate smaller polar nanoregions (PNRs), suppress their overgrowth, and increase the number of dynamically active PNRs at room temperature, leading to enhanced permittivity ε′ while preserving DC-bias stability and breakdown strength (EB). Reduction annealing generates Nb4+-related local polarizations aligned with the external electric field, which strengthen dipole fluctuations and slightly increase ε′. Electron localization further relaxes the TTB-A2 site disorder–induced random fields, yielding a sharper dielectric peak and promoting more uniform PNR growth. Microwave dielectric spectroscopy combined with electromagnetic simulations revealed that the increases in ε′ for both Ti-loaded and reduced samples (0.5-SBNT and Reduced 0.5-SBN, respectively) originate predominantly from enhanced dipole polarization. Despite grain coarsening in 0.5-SBNT, the EB remained unchanged, indicating that defect dipoles act as pinning centers that inhibit field-induced PNR aggregation. In reduced 0.5-SBN, EB increased up to pO0 = 4.3 × 10−3 atm owing to relaxed random fields, whereas excessive reduction reduced EB through carrier-driven space-charge effects. These results demonstrate that precise control of defect species enables simultaneous optimization of ε′, DC-bias stability, and EB in TTB-type relaxor ferroelectrics. en-copyright= kn-copyright= en-aut-name=ShiotaRyusei en-aut-sei=Shiota en-aut-mei=Ryusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoShinya en-aut-sei=Kondo en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira 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=Department of Energy Engineering, Nagoya University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Relaxor ferroelectrics kn-keyword=Relaxor ferroelectrics en-keyword=(Sr,Ba)Nb2O6 kn-keyword=(Sr,Ba)Nb2O6 en-keyword=Polar nanoregions kn-keyword=Polar nanoregions en-keyword=Dipole polarization kn-keyword=Dipole polarization en-keyword=DC bias response kn-keyword=DC bias response END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=128 end-page=135 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Developing and Implementing a Disaster Prevention Game to Enhance Local Understanding en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study developed and implemented a local disaster prevention sugoroku-style game to address challenges in preserving and transmitting regional knowledge in areas with high population mobility. Many Japanese communities face both natural and social vulnerabilities, and effective disaster education requires linking hazard knowledge with local characteristics. Conducted at Sonan Junior High School in Okayama, the project combined lectures, workshops, and a community engagement event. Students learned about regional topography, land use, and disaster history and used this knowledge to design quizzes, rules, and disaster scenarios for the game. The final sugoroku set included a map-based board, thematic quiz areas, and preparedness item cards, enabling players to predict damage and consider appropriate actions. After creating the game, students shifted from identifying familiar landmarks to describing concrete disaster impacts such as liquefaction or infrastructure collapse. Interaction with local residents further enriched learning through shared experiences. The model proved feasible in terms of time and cost, and its structure is easily adaptable to other regions by incorporating local information. The findings suggest that this participatory, place-based approach enhances imagination, self-efficacy, and intergenerational knowledge transfer, contributing to community-wide disaster preparedness. Future studies will examine long-term educational impacts and broader regional applications. en-copyright= kn-copyright= en-aut-name=ShirokaneMiri en-aut-sei=Shirokane en-aut-mei=Miri kn-aut-name=

stem en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: ACTIS and CORAIL are cementless titanium femoral stems with hydroxyapatite (HA) coating but differing macro-geometries: ACTIS features a variable triple-taper with a medial collar, whereas CORAIL is a straight double-tapered design available with or without a collar. We compared mid-term clinical and radiographic outcomes of these stems with a minimum 5-years follow-up.
Methods: We retrospectively reviewed 114 primary total hip arthroplasties using ACTIS (63 hips) or CORAIL (51 hips). Clinical outcomes and standardized radiographic parameters were assessed and compared between groups.
Results: The canal-fill ratio (CFR) was significantly greater at the proximal, middle, and distal levels in the ACTIS group. Spot-weld formation was more frequent with ACTIS than with CORAIL (58.7% vs 35.3%). In logistic regression, proximal CFR significantly predicted spot-weld formation for ACTIS, with an optimal cutoff of 66.2% (sensitivity 91.9%, specificity 72.0%). Rates of subsidence, radiolucent lines, and pedestal formation did not differ significantly between groups. No severe stress shielding was observed with ACTIS, whereas three CORAIL hips demonstrated severe stress shielding (0% vs 5.9%). Clinical scores improved significantly in both groups, with no significant between-group differences at final follow-up.
Conclusions: Both stems yielded favorable radiographic and clinical mid-term outcomes. In ACTIS, greater proximal canal fill was associated with radiographic osseointegration, suggesting proximal CFR as a probabilistic radiographic marker of stem ingrowth. en-copyright= kn-copyright= en-aut-name=MasadaYasutaka en-aut-sei=Masada en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiwaraKazuo en-aut-sei=Fujiwara en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama City General Medical Center, Okayama City Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Center for Education in Medicine and Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=ACTIS kn-keyword=ACTIS en-keyword=CORAIL kn-keyword=CORAIL en-keyword=mid-term outcome kn-keyword=mid-term outcome en-keyword=retrospective study kn-keyword=retrospective study END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Performance of the modified 2022 ACR/EULAR giant cell arteritis classification criteria without age restriction for discriminating from Takayasu arteritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective To evaluate the ability to discriminate giant cell arteritis (GCA) from Takayasu arteritis (TAK) according to the modified 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology (ACR/EULAR) GCA classification criteria.
Methods Patients enrolled in the Japanese nationwide retrospective registry were evaluated using the criteria with partial modification; wall thickening of descending thoracic-abdominal aorta were mainly diagnosed by contrast-enhanced computed tomography (CT) or magnetic resonance imaging instead of evaluating with positron emission tomography (PET)-CT. The discriminability of the criteria was evaluated using C-statistic (> 0.7: good ability).
Results Newly diagnosed patients with GCA (n = 139) and TAK (n = 129) were assessed, and 23.3% of TAK were aged 50 years or older at onset. The sensitivity of the modified 2022 ACR/EULAR GCA classification criteria with a score ≥ 6 was 82.0%, 68.5%, and 32.1% in all GCA, GCA with large-vessel involvement, and GCA without cranial arteritis, respectively. The specificity of the modified criteria was 96.1% for the 129 TAK as controls. Five patients with late-onset TAK met the modified criteria, and four had cranial signs and symptoms, two had bilateral axillary artery involvement, and four had descending thoracic-abdominal aorta involvement. The discriminability of the criteria was good (C-statistic: 0.986, 95% confidence interval [CI]: 0.976–0.996) and remained good after excluding age (C-statistic: 0.927, 95% CI: 0.894–0.961). The discriminability of a set of large-vessel lesions (bilateral axillary artery and descending thoracic-abdominal aorta) and inflammatory markers was markedly decreased with poor C-statistic value (C-statistic: 0.598, 95% CI: 0.530–0.667). Discriminability was improved after adding polymyalgia rheumatica (PMR) (C-statistic: 0.757, 95% CI: 0.700–0.813) or age (C-statistic: 0.913, 95%CI: 0.874–0.951) to the set of large-vessel lesions. In GCA patients with a score ≤ 5, 52% had bilateral subclavian and/or axillary artery involvement.
Conclusion The modified 2022 ACR/EULAR GCA classification criteria well performed in classifying GCA and TAK without PET-CT in routine clinical practice. A set of items included in the modified GCA classification criteria had good discriminative ability for GCA and TAK, even when age was excluded. However, age restriction or PMR was required to distinguish GCA without cranial lesions from TAK. en-copyright= kn-copyright= en-aut-name=SugiharaTakahiko en-aut-sei=Sugihara en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HarigaiMasayoshi en-aut-sei=Harigai en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=YoshifujiHajime en-aut-sei=Yoshifuji en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaejimaYasuhiro en-aut-sei=Maejima en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshizakiJun en-aut-sei=Ishizaki en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeYoshiko en-aut-sei=Watanabe en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DobashiHiroaki en-aut-sei=Dobashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KomagataYoshinori en-aut-sei=Komagata en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TamuraNaoto en-aut-sei=Tamura en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaokaYoshikazu en-aut-sei=Nakaoka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Japan Research Committee of the Ministry of Health, Labour, and Welfare for Intractable Vasculitis (JPVAS) en-aut-sei=Japan Research Committee of the Ministry of Health, Labour, and Welfare for Intractable Vasculitis (JPVAS) en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Rheumatology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=2 en-affil=Division of Rheumatology, Department of Internal Medicine, Tokyo Women’s Medical University School of Medicine kn-affil= affil-num=3 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Rheumatology and Clinical Immunology, Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=6 en-affil=Department of Hematology, Clinical Immunology and Infectious Diseases, Ehime University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of General Medicine, Kawasaki Medical School kn-affil= affil-num=8 en-affil=Division of Hematology, Rheumatology and Respiratory Medicine, Department of Internal Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Department of Nephrology and Rheumatology, Kyorin University School of Medicine kn-affil= affil-num=10 en-affil=Department of Internal Medicine and Rheumatology, Juntendo University School of Medicine kn-affil= affil-num=11 en-affil=Department of Vascular Physiology, National Cerebral and Cardiovascular Center Research Institute kn-affil= affil-num=12 en-affil= kn-affil= en-keyword=GCA kn-keyword=GCA en-keyword=TAK kn-keyword=TAK en-keyword=Classification criteria kn-keyword=Classification criteria en-keyword=Bilateral axillary artery kn-keyword=Bilateral axillary artery en-keyword=Descending thoracic-abdominal aorta kn-keyword=Descending thoracic-abdominal aorta en-keyword=Bilateral subclavian artery kn-keyword=Bilateral subclavian artery END start-ver=1.4 cd-journal=joma no-vol=2025 cd-vols= no-issue=1 article-no= start-page=013A01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Saddle-Point Approximation to the False-Vacuum Decay at Finite Temperature in 1D Quantum Mechanics en-subtitle= kn-subtitle= en-abstract= kn-abstract=We calculate the false-vacuum decay rate in 1D quantum mechanics on the basis of the saddle-point approximation in the Euclidean path integral at finite temperature.

We reexamine the zero-temperature result by Callan and Coleman and compare it with the zero-temperature limit of our results. We also perform some numerical calculations to illustrate the temperature dependence of the decay rate and compare it with the result by Affleck. en-copyright= kn-copyright= en-aut-name=HaradaKoji en-aut-sei=Harada en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaoShuichiro en-aut-sei=Tao en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YinQiang en-aut-sei=Yin en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Arts and Science, Kyushu University kn-affil= affil-num=2 en-affil=Institute of Promotion of Education and Campus Life, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Science, Kyushu University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=10055 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nitric oxide induces p53-mediated cell death in human nasal epithelial cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nitric oxide (NO) is a key signaling molecule that plays a vital role in maintaining homeostasis of physiological processes such as immune responses and neurotransmission. However, excessive NO production during inflammatory responses to infection can lead to cytotoxicity and tissue damage. The nasal epithelial barrier is a crucial first line of immunological defense against viral infections, and it is likely exposed to excessive NO levels during chronic inflammation. Therefore, clarifying the effects of NO on this barrier is thus critical. In this study, we investigated the biological effects of sustained NO exposure on RPMI2650 human nasal epithelial cells. Post-NO exposure transcriptomic analyses revealed significant upregulation of genes involved in the p53 signaling pathway. RT-qPCR analyses confirmed the temporal upregulation of p53 target genes associated with apoptosis and cell cycle regulation. These gene expression changes downregulated cell proliferation and induced cell death. Our findings suggest that excessive NO exposure induces nasal epithelial cell death via the p53 pathway, which over the long term can result in tissue damage and dysfunction under inflammatory conditions. These results provide new insights into how prolonged NO exposure affects the nasal epithelial cells and may contribute to the progression of chronic infectious diseases. en-copyright= kn-copyright= en-aut-name=KamiuezonoShizuki en-aut-sei=Kamiuezono en-aut-mei=Shizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchidaTomoki en-aut-sei=Tsuchida en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara 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 Medicinal Pharmacology, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Nitric oxide kn-keyword=Nitric oxide en-keyword=p53 kn-keyword=p53 en-keyword=Apoptosis kn-keyword=Apoptosis en-keyword=Cell death kn-keyword=Cell death en-keyword=Human nasal epithelial cells kn-keyword=Human nasal epithelial cells END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=6 article-no= start-page=680 end-page=684 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=Effects of heat stress on gene expression associated with antioxidant capacity of bovine early antral follicles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heat exposure at the physiological level of oocyte-cumulus-granulosa cell complexes (OCGCs) during in vitro growth (IVG) culture decreases the reduced glutathione (GSH) level of oocytes, an antioxidant, but its mechanism has been unclear. We subjected OCGCs to IVG for 4, 8, or 12 days and investigated the effects of heat exposure on the gene expression of cumulus-granulosa cells associated with antioxidant capacity. Heat exposure did not alter the expression of genes related to GSH synthesis or reuse. Conversely, heat exposure increased mRNA expression of superoxide dismutase 2 and decreased that of glutathione peroxidase 1, which are antioxidant enzymes. Ultimately, heat exposure alters the gene expression of antioxidant enzymes in growing follicles, which may indirectly decrease the GSH level of oocytes. en-copyright= kn-copyright= en-aut-name=KAWANOKohei en-aut-sei=KAWANO en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SAKAGUCHIKenichiro en-aut-sei=SAKAGUCHI en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FURUKAWAEri en-aut-sei=FURUKAWA en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NINPETCHNattapong en-aut-sei=NINPETCH en-aut-mei=Nattapong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YANAGAWAYojiro en-aut-sei=YANAGAWA en-aut-mei=Yojiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KATAGIRISeiji en-aut-sei=KATAGIRI en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Veterinary Theriogenology, Joint Department of Veterinary Medicine, Faculty of Applied Biological Sciences, Gifu University kn-affil= affil-num=3 en-affil=National Institute of Animal Health, National Agriculture and Food Research Organization kn-affil= affil-num=4 en-affil=Department of Animal Science, Faculty of Agriculture at Kamphaeng Saen, Kasetsart University kn-affil= affil-num=5 en-affil=Laboratory of Theriogenology, Department of Clinical Sciences, Division of Veterinary Medicine, Faculty of Veterinary Medicine, Hokkaido University kn-affil= affil-num=6 en-affil=Laboratory of Theriogenology, Department of Clinical Sciences, Division of Veterinary Medicine, Faculty of Veterinary Medicine, Hokkaido University kn-affil= en-keyword=antioxidant capacity kn-keyword=antioxidant capacity en-keyword=bovine kn-keyword=bovine en-keyword=early antral follicle kn-keyword=early antral follicle en-keyword=in vitro growth kn-keyword=in vitro growth en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=10 article-no= start-page=1199 end-page=1202 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240711 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of quercetin as a potential cytoprotector against acetaldehyde using the cultured hepatocyte model with aldehyde dehydrogenase isozyme deficiency en-subtitle= kn-subtitle= en-abstract= kn-abstract=Protective effect of quercetin against acetaldehyde was evaluated using the cultured hepatocyte models with aldehyde dehydrogenase (ALDH) isozyme deficiency (aldh2-kd and aldh1a1-kd).

We assume that the degree (i.e., power) of the nonlinearity is such that the equation is mass-subcritical and short-range. We establish global well-posedness (GWP) and scattering for small data in the standard weighted space for a class of homogeneous nonlinearities, including non-gauge-invariant ones. Additionally, we include the case where the degree is less than or equal to the Strauss exponent. When the nonlinearity is not gauge-invariant, the standard Duhamel formulation fails to work effectively in the weighted Sobolev space; for instance, the Duhamel term may not be well-defined as a Bochner integral. To address this issue, we introduce an alternative formulation that allows us to establish GWP and scattering, even in the presence of poor time continuity of the Duhamel term. en-copyright= kn-copyright= en-aut-name=KawamotoMasaki en-aut-sei=Kawamoto en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MasakiSatoshi en-aut-sei=Masaki en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyazakiHayato en-aut-sei=Miyazaki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Mathematics, Hokkaido University kn-affil= affil-num=3 en-affil=Teacher Training Courses, Faculty of Education, Kagawa University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=24 article-no= start-page=245001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acceleration of Positive Muons by a Radio-Frequency Cavity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acceleration of positive muons from thermal energy to 100 keV has been demonstrated. Thermal muons were generated by resonant multiphoton ionization of muonium atoms emitted from a sheet of laser-ablated aerogel. The thermal muons were first electrostatically accelerated to 5.7 keV, followed by further acceleration to 100 keV using a radio-frequency quadrupole with an intensity of 2×10−3  𝜇+/pulse. The transverse normalized rms emittance of the accelerated muons in the horizontal and vertical planes were 0.85±0.25⁢(s⁢t⁢a⁢t)+0.22−0.13⁢(syst)   ⁢𝜋 mm mrad and 0.32±0.03⁢(stat)+0.05−0.02⁢(syst)   𝜋 mm mrad, respectively. The measured emittance values demonstrated phase-space reduction by a factor of 2.0 ×102 (horizontal) and 4.1 ×102 (vertical) allowing good acceleration efficiency. These results pave the way to realize the first-ever muon accelerator for a variety of applications in particle physics, material science, and other fields. en-copyright= kn-copyright=

en-abstract= kn-abstract=tRNA 2-thiouridine synthesizing protein A (TusA), a sulfur-carrier protein, plays a crucial role in tRNA sulfur modification. Several studies have reported that tusA deficiency affects iron–sulfur (Fe–S) homeostasis in addition to tRNA sulfur modification, resulting in pleiotropic phenotypes. In this study, we analyzed the phenotype of tusA-deficient Escherichia coli and its underlying mechanisms. Although the Keio tusA knockout strain showed increased swimming motility and flagellar biosynthesis, these phenotypes were not restored by tusA complementation. Genome resequencing of the original Keio tusA knockout strain identified an unintended secondary mutation in lrhA, a transcriptional regulator of flagellar and chemotaxis genes. This secondary mutation impaired lrhA function, contributing to enhanced flagellar synthesis and swimming motility, as well as altered global gene expression. A tusA knockout strain in which the secondary mutation was corrected (ΔtusA) exhibited reduced swimming motility compared with the wild-type strain, despite showing no abnormalities in flagellar formation. Furthermore, ΔtusA displayed increased resistance to cationic antibacterial agents, including cetyltrimethylammonium bromide, cetylpyridinium chloride, and protamine sulfate. The reduced motility caused by tusA deletion was observed independently of Fur, a global regulator of iron homeostasis, whereas resistance to cationic antibacterial agents was abolished in the fur knockout background. In addition, altered expression of outer membrane protein (omp) genes was observed in ΔtusA, and deletion of these omp genes abolished resistance to cationic antibacterial agents. Together, these results indicate that, by disentangling the phenotypic effects of tusA deletion from those of the unintended secondary mutation, loss of tusA confers resistance to cationic antibacterial agents through a Fur-dependent and Omp-dependent mechanism. en-copyright= kn-copyright= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei=

と幸福感の関連が報告されているが、多くは横断研究であり、時間的方向性を考慮した検討は不十分である。そこで本研究では、日本の40 歳以上の成人585 名を対象に、AARC 短縮版（AARC-10 SF）、人生満足度尺度（SWLS）、心理的ストレス尺度（K6）を用いて、2 時点（2022 年7 月、2023 年10 月）でオンライン調査を実施した。交差遅延効果モデルの分析の結果、AARC-gains とSWLS の間に双方向の関連が認められ、AARC-gains が高い人ほど後の主観的幸福感が高く、その逆も成立することが示された。一方、心理的ストレスはAARC-losses に対して一方向の関連が確認され、ストレスが高い人ほど後のAARC-losses が高いことが示された。これらの結果は、ライフスパン発達理論の枠組みと整合し、加齢に伴う適応過程の理解を深めるものである。介入においては、AARC-gains を促進し幸福感を高めることが高齢者のサクセスフル・エイジングに寄与する可能性がある。 en-copyright= kn-copyright= en-aut-name=ShiraishiNatsue en-aut-sei=Shiraishi

kn-title=Whole-genome-based characterization of Escherichia albertii strains isolated from paediatric diarrhoeal cases in Kolkata, India en-subtitle= kn-subtitle= en-abstract= kn-abstract=Escherichia albertii is a Gram-negative facultative anaerobic bacterium that causes diarrhoea in humans. This study shows the isolation of E. albertii from hospitalized paediatric diarrhoeal cases and genome-based characteristics with putative virulence factors and antimicrobial resistance. E. albertii isolates were identified by species-specific PCR, targeting the gene encoding cytolethal distending toxin (Ea-cdt). The genome of E. albertii was sequenced to identify (i) genes encoding virulence factors (ii) antibiotic resistance-encoding genes, including the mobile genetic elements and (iii) core gene-based phylogenetic relationships and pan-genome features. A total of 10 (1.2%) E. albertii isolates were isolated from 854 faecal samples, of which 6 (60%) were found as the sole pathogen and the remaining 4 (40%) were identified along with other pathogens, such as enteroaggregative Escherichia coli, rotavirus and adenovirus. Patients from whom E. albertii was isolated presented cholera-like diarrhoea, i.e. with watery stool (60%) with moderate dehydration (100%), fever (20%) and abdominal pain (20%). The antimicrobial susceptibility testing of E. albertii showed that most of the isolates were susceptible or reduced susceptible to most of the antibiotics except resistance to erythromycin (80%), tetracycline (50%), nalidixic acid (40%), ampicillin (40%), doxycycline (30%) and ceftriaxone (20%). In the whole-genome sequence, E. albertii isolates revealed several virulence-encoding genes, namely the intimin (eae, E. coli attaching and effacing), the cytolethal distending toxin type II subunit A (cdt-IIA), adhesion (paa, porcine attaching- and effacing-associated), non-LEE (locus of enterocyte effacement) encoded effector A (nleA) and antimicrobial resistance genes (ARGs) conferring resistance to tetracycline (tetA, tetR), sulphonamides (sul2), fluoroquinolones (qnrS) and beta-lactamases (blaCTX-M, blaTEM). The SNP-based phylogenetic analysis of 647 whole genomes of E. albertii isolates from the National Center for Biotechnology Information databases did not reveal any comparable clustering pattern based on the biological source and place of isolation. The genome of some of the E. albertii was closely related to those of the isolates from China and the United Kingdom. The PFGE patterns revealed that most of the E. albertii isolates were distinct clones. This study reports on the extensive genome analysis of diarrhoea-associated E. albertii harbouring multiple virulence and ARGs. en-copyright= kn-copyright= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HoshikoYuki en-aut-sei=Hoshiko en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkunoMiki en-aut-sei=Okuno en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=AlbertM John en-aut-sei=Albert en-aut-mei=M John kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=OguraYoshitoshi en-aut-sei=Ogura en-aut-mei=Yoshitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=2 en-affil=Division of Microbiology, Department of Infectious Medicine, School of Medicine, Kurume University kn-affil= affil-num=3 en-affil=Division of Microbiology, Department of Infectious Medicine, School of Medicine, Kurume University kn-affil= affil-num=4 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=5 en-affil=Department of Microbiology, College of Medicine, Kuwait University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Microbiology, Department of Infectious Medicine, School of Medicine, Kurume University kn-affil= affil-num=8 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=9 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=10 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=diarrhoea kn-keyword=diarrhoea en-keyword=E. albertii kn-keyword=E. albertii en-keyword=virulence kn-keyword=virulence en-keyword=whole-genome sequence kn-keyword=whole-genome sequence END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=57 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical conductivity measurements of rhyolitic glass at high pressure and high temperature en-subtitle= kn-subtitle= en-abstract= kn-abstract=We performed electrical conductivity measurements of rhyolite glasses across the glass transition temperature at 1 GPa. Our experimental data show that, in the Arrhenius plot, the conductivity of rhyolite with 0.2 wt% H2O has an inflection point between around 760 K, while for rhyolite with 4.9 wt% H2O the gradient changes between 685 and 825 K. These inflection points correlate with the glass transition temperature, and are compared with results of previous experiments. The degree of welding of clastic and hydrous rock can be constrained by estimating glass transition temperatures of volcanic rocks combined with measurements of electrical conductivity structures obtained from electromagnetic soundings beneath volcanic bodies. This, in turn, can be used to aid predictions of volcanic eruption. en-copyright= kn-copyright= en-aut-name=HaraguchiYusuke en-aut-sei=Haraguchi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Fuji-TaKiyoshi en-aut-sei=Fuji-Ta en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamotoMasashi en-aut-sei=Nakamoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiMasanori en-aut-sei=Suzuki en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaToshihiro en-aut-sei=Tanaka en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=2 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=5 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=6 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= en-keyword=Electrical conductivity kn-keyword=Electrical conductivity en-keyword=Glass transition temperature kn-keyword=Glass transition temperature en-keyword=melt kn-keyword=melt en-keyword=clastics kn-keyword=clastics END start-ver=1.4 cd-journal=joma no-vol=295 cd-vols= no-issue= article-no= start-page=51 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel spontaneous rat model of chronic kidney disease with mitochondrial dysfunction driven by thioredoxin insufficiency en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Chronic kidney disease (CKD) is a global health burden with high prevalence and poor prognosis. Although oxidative stress and mitochondrial dysfunction have been implicated in its pathogenesis, in vivo causal evidence remains limited. Thioredoxin (Trx), encoded by Txn1, is a redox-active protein that plays a central role in controlling oxidative stress and maintaining intracellular redox homeostasis.
Methods: To address this gap, we investigated the lifelong phenotypes of Txn1-F54L mutant rats harboring approximately one-third of the normal Trx activity. These rats were generated via N-ethyl-N-nitrosourea mutagenesis and validated by clustered regularly interspaced palindromic repeat (CRISPR)/CRISPR-associated protein 9 genome editing. Comprehensive analyses included biochemical testing, histopathology, immunohistochemistry, transmission electron microscopy, RNA-sequencing, western blotting, and cytokine profiling.
Results: Txn1-F54L mutant rats spontaneously developed progressive CKD, with median survival times of 110–119 days for homozygotes and 303–346 days for heterozygotes. Their clinical features—elevated blood urea nitrogen, hypoalbuminemia, hypercholesterolemia, hypertension, and arterial medial sclerosis—closely resembled those of human CKD. Histopathological evaluation revealed extensive tubular injury, interstitial fibrosis, and glomerulosclerosis. Transcriptomic profiling identified 3,418 differentially expressed genes significantly enriched in immune activation and fibrosis pathways. Mitochondrial dysfunction was prominent in proximal tubules, accompanied by oxidative stress accumulation and concurrent activation of regulated cell death pathways (apoptosis, necroptosis, and pyroptosis). Elevated serum levels of interleukin-1β, interleukin-6, and interferon-γ indicated systemic inflammation.
Conclusions: Our findings demonstrate that lifelong Trx deficiency induces oxidative stress–mediated mitochondrial dysfunction and regulated cell death, leading to inflammation and progressive CKD. This study establishes the Txn1 mutant rat as a valuable spontaneous CKD model, providing translational insights and a platform for developing therapeutic strategies targeting oxidative stress–induced pathways. en-copyright= kn-copyright= en-aut-name=OhmoriIori K. en-aut-sei=Ohmori en-aut-mei=Iori K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OuchidaMamoru en-aut-sei=Ouchida en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HadaYoshiko en-aut-sei=Hada en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=ToyokuniShinya en-aut-sei=Toyokuni en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MashimoTomoji en-aut-sei=Mashimo en-aut-mei=Tomoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Section of Developmental Physiology and Pathology, Faculty of Education, Okayama University kn-affil= affil-num=2 en-affil=Department of Molecular Oncology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Biological Responses, Nagoya University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Division of Animal Genetics, Laboratory Animal Research Center, Institute of Medical Science, The University of Tokyo kn-affil= en-keyword=Chronic kidney disease kn-keyword=Chronic kidney disease en-keyword=Mitochondria kn-keyword=Mitochondria en-keyword=Thioredoxin kn-keyword=Thioredoxin en-keyword=Trx kn-keyword=Trx en-keyword=Txn1 kn-keyword=Txn1 en-keyword=Regulated cell death kn-keyword=Regulated cell death END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=185 end-page=193 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reducing Hesitation in Resuscitation: Educational Effects of a Female-Appearing Simulator in Basic Life Support Training en-subtitle= kn-subtitle= en-abstract= kn-abstract=Women are less likely than men to receive timely defibrillation during out-of-hospital cardiac arrest. We investigated whether using a simulator that is visually modified to resemble a female affects learners’ attitudes, knowledge, and performance in basic life support (BLS) training. In a BLS simulation training, first-year medical students (n=220) used a standard gender-neutral simulator (control group) or a modified simulator with a female-like appearance (intervention group). Pre- and post-training questionnaires concerning attitudes and knowledge plus a post-training skills evaluation assessed the students’ training outcomes. The intervention group initiated chest compressions significantly faster than the control group (33.1 vs. 39.8 sec, p<0.01) and achieved a significantly higher rate of correct AED pad placement (64.2% vs. 38.5%, p<0.01). While performing the resuscitation on the female-appearing manikin, the intervention group showed significantly greater increases in self-efficacy (p<0.01) and larger decreases in discomfort about removing the patient’s clothes (p<0.01). They were also significantly more likely to recognize that chest compressions can be performed (p=0.016) and AED pads can be applied (p=0.015) without removing the patient’s underwear. Using a female-appearing simulator in BLS training was thus associated with faster chest compression initiation, more accurate AED pad placement, and improved gender-sensitive attitudes and knowledge. en-copyright= kn-copyright= en-aut-name=KuboTakuya en-aut-sei=Kubo en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=resuscitation kn-keyword=resuscitation en-keyword=basic life support kn-keyword=basic life support en-keyword=female simulator kn-keyword=female simulator en-keyword=medical education kn-keyword=medical education en-keyword=gender bias kn-keyword=gender bias END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=169 end-page=178 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Peripheral Blood T-Cell Receptor Repertoire and Host Immune Background in Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=The association between peripheral blood T-cell receptor (TCR) repertoire and chemotherapy response remains unclear. We evaluated peripheral blood TCR repertoire and gut microbiota in 21 breast cancer patients receiving neoadjuvant chemotherapy (NAC) who were enrolled in the SBP-14 prospective cohort study between October 2019 and March 2022. We analyzed stool samples obtained pre-NAC and peripheral blood samples obtained pre- and post-NAC. The primary endpoint was the association between baseline peripheral blood TCR repertoire and treatment response. Eleven patients (52%) had hormone receptor-positive breast cancer. All patients received anthracyclines and taxanes, with anti-HER2 therapy for HER2-positive disease. TCR diversity (TCR alpha chain [TRA], p=0.095; TCR beta chain [TRB], p=0.051) and clonality (TRA, p=0.271; TRB, p=0.500) were not significantly associated with treatment response. Gut microbiota diversity was not correlated with TCR diversity (TRA: ρ=0.046, p=0.845; TRB: ρ=0.021, p=0.929); however, three bacterial orders (Erysipelotrichales, Bacillales, and Pasteurellales) were significantly associated with TCR repertoire. Baseline TCR repertoire was not associated with treatment response in this cohort of breast cancer patients. en-copyright= kn-copyright= en-aut-name=NakamuraYuki en-aut-sei=Nakamura en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamotoTakayuki en-aut-sei=Iwamoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KajiwaraYukiko en-aut-sei=Kajiwara en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidaAkira en-aut-sei=Hida en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamotoShogo en-aut-sei=Nakamoto en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiYuichiro en-aut-sei=Miyoshi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=IkedaMasahiko en-aut-sei=Ikeda en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=OgataRyohei en-aut-sei=Ogata en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoikeYoshikazu en-aut-sei=Koike en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NomuraTsunehisa en-aut-sei=Nomura en-aut-mei=Tsunehisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TanakaKatsuhiro en-aut-sei=Tanaka en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NakashimaKazutaka en-aut-sei=Nakashima en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YamatsujiTomoki en-aut-sei=Yamatsuji en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=2 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=3 en-affil=Department of Breast Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Pathology, Matsuyama Shimin Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Breast Endocrine Surgery, Kagawa Prefectural Center Hospital kn-affil= affil-num=7 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Breast and Thyroid Surgery, Fukuyama City Hospital kn-affil= affil-num=9 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=10 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=11 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=12 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=13 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=14 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=15 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=16 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= en-keyword=TCR repertoire kn-keyword=TCR repertoire en-keyword=gut microbiota kn-keyword=gut microbiota en-keyword=neoadjuvant chemotherapy kn-keyword=neoadjuvant chemotherapy en-keyword=breast cancer kn-keyword=breast cancer END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=159 end-page=168 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Self-Reported Adolescent Menstrual Symptoms and Delayed Gynecologic Consultation among Japanese Women with Endometriosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endometriosis symptoms often first appear during adolescence, yet delays in seeking gynecologic consultation remain a persistent challenge worldwide. Despite growing international evidence, the specific patterns of symptom recognition and consultation delay among Japanese women — particularly in relation to self-monitoring behaviors and cultural barriers — remain poorly understood. This study aimed to provide foundational data to guide menstrual education and preconception care strategies by conducting a cross-sectional online survey with retrospective recall among women with endometriosis to assess menstrual characteristics and symptom patterns from adolescence to initial care seeking. The survey was conducted in Japan in January 2024 and enrolled 166 women with endometriosis and 200 controls. Participants reported current and adolescent menstrual characteristics, symptom recognition, analgesic and low-dose estrogen–progestin use, school/work impact, and age at first gynecologic consultation for menstrual problems. Women with endometriosis reported heavier bleeding, stronger pain, and greater school/work absence than controls, both currently and retrospectively. The median age at first recognition of heavy bleeding or school/work absence was 16 years, whereas consultation occurred at approximately 21-23 years, indicating a consultation delay of 5-6 years. Notably, while self-monitoring of symptoms was more frequent among women with endometriosis, it only modestly shortened consultation delays. This study provides evidence from Japan that consultation delay persists despite active self-monitoring of symptoms, highlighting the influence of educational and cultural barriers on health-seeking behavior. These findings underscore the importance of integrating menstrual education with clinical guidance to promote timely gynecologic consultation. en-copyright= kn-copyright= en-aut-name=IkedaTomoko en-aut-sei=Ikeda en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakatsukaMikiya en-aut-sei=Nakatsuka en-aut-mei=Mikiya 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= en-keyword=endometriosis kn-keyword=endometriosis en-keyword=adolescence kn-keyword=adolescence en-keyword=menstrual disorders kn-keyword=menstrual disorders en-keyword=consultation delay kn-keyword=consultation delay en-keyword=health-seeking behavior kn-keyword=health-seeking behavior END start-ver=1.4 cd-journal=joma no-vol=135 cd-vols= no-issue=4 article-no= start-page=747 end-page=759 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of cross-modal negative BOLD responses in the human sensory subcortex and cortex en-subtitle= kn-subtitle= en-abstract= kn-abstract=Functional magnetic resonance imaging (fMRI) is a noninvasive method for measuring human brain activity based on blood oxygenation level-dependent (BOLD) responses. Although many studies have reported positive BOLD responses evoked by sensory stimuli, others have reported negative BOLD responses (NBRs) in the sensory cortex when stimuli from different sensory modalities are presented (i.e., cross-modal NBRs). We conducted an fMRI experiment to better understand the characteristics of cross-modal NBRs in subcortical and cortical regions. Auditory and visual stimuli were presented unilaterally to one ear and to either the left or right visual field, respectively. The lateral geniculate nucleus and medial geniculate nucleus did not show a significant cross-modal NBR. In contrast, the primary auditory cortex showed a significant cross-modal NBR when visual stimuli were presented in either the contralateral or ipsilateral visual fields. Finally, we found that the cross-modal NBR in the early visual cortex was highly variable across subjects and did not exhibit consistent trends. However, each subject’s data exhibited considerable split-half reliability. Our results suggest that cross-modal NBR in the auditory cortex likely reflects mechanisms such as interhemispheric suppression, rather than those coordinated within the same hemisphere.
NEW & NOTEWORTHY This study demonstrated that the human primary auditory cortex showed a significant cross-modal negative BOLD response bilaterally, regardless of the visual field in which the visual stimuli were presented. This result suggests that the cross-modal negative BOLD response is not an epiphenomenon of visual cortex activation predominantly observed in the contralateral hemisphere, but is more likely to reflect interhemispheric suppression mechanisms. en-copyright= kn-copyright= en-aut-name=MiyataToshikazu en-aut-sei=Miyata en-aut-mei=Toshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukunagaMasaki en-aut-sei=Fukunaga en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LuoJunxiang en-aut-sei=Luo en-aut-mei=Junxiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoiIsao en-aut-sei=Yokoi en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoTetsuya en-aut-sei=Yamamoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiokaAyumi en-aut-sei=Yoshioka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=MoritaTomoyo en-aut-sei=Morita en-aut-mei=Tomoyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakemuraHiromasa en-aut-sei=Takemura en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Sensory and Cognitive Brain Mapping, Department of System Neuroscience, National Institute for Physiological Sciences kn-affil= affil-num=2 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=3 en-affil=Division of Sensory and Cognitive Brain Mapping, Department of System Neuroscience, National Institute for Physiological Sciences kn-affil= affil-num=4 en-affil=National Institute for Physiological Sciences kn-affil= affil-num=5 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=6 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Center for Information and Neural Networks (CiNet), Advanced ICT Research Institute, National Institute of Information and Communications Technology (NICT) kn-affil= affil-num=9 en-affil=Division of Sensory and Cognitive Brain Mapping, Department of System Neuroscience, National Institute for Physiological Sciences kn-affil= en-keyword=auditory system kn-keyword=auditory system en-keyword=cross-modal kn-keyword=cross-modal en-keyword=functional MRI kn-keyword=functional MRI en-keyword=visual system kn-keyword=visual system 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=2026 dt-pub=20260521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr ‐mutated lung cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancers (NSCLCs) lack effective immunotherapy due to a noninflamed tumor microenvironment (TME). We previously reported that EGFR tyrosine-kinase-inhibitor (TKI) induced CD8+ T-cell immunity, which was insufficient for tumor eradication. We evaluated the potential of combining EGFR-TKI with stimulator of interferon genes (STING) agonists in activating a systemic antitumor response. Using a syngeneic mouse model of genetically engineered Egfr-mutant NSCLC, we evaluated the antitumor effects of STING agonist ADU-S100, alone and combined with osimertinib. Immunohistochemistry and flow cytometry were used to assess the TME. Osimertinib alone enhanced CD8+ T-cell infiltration but not Natural Killer (NK) cell infiltration. ADU-S100 injection alone modestly suppressed tumor growth with increasing CD8+/NK cell infiltration in the TME, but lacked an abscopal effect. Combining ADU-S100 with osimertinib significantly enhanced the antitumor effects and CD8+/NK cell infiltration. Depletion of either CD8+ or NK cells reduced the combination effect. Crucially, the combination induced an abscopal effect accompanied by PD-1+/CD8+ cell infiltration. Combining osimertinib with a STING agonist augmented innate and adaptive immunity, inducing systemic antitumor responses in EGFR-mutant NSCLC. en-copyright= kn-copyright= en-aut-name=NishimuraJun

ribosome en-subtitle= kn-subtitle= en-abstract= kn-abstract=ATP-binding cassette subfamily F (ABCF) proteins interact with the ribosome to resolve translation defects near the peptidyl transferase center (PTC). In Escherichia coli, four ABCF proteins (EttA, Uup, YbiT, and YheS) selectively promote translation of distinct problematic nascent peptide sequences, but their molecular mechanisms remain unclear. Here, we present a 2.8 Å cryo-EM structure of the ribosome in complex with an ATPase-deficient mutant of YheS and investigate how it releases ribosomes arrested by the SecM nascent chain. YheS binds to the ribosomal E-site via the L1 stalk, and its P-site tRNA-interaction motif (PtIM) extends toward the PTC, displacing the CCA end of the P-site tRNA. Notably, the cryo-EM density corresponding to the SecM nascent chain within the exit tunnel is largely lost upon YheS binding. These observations suggest that YheS relieves peptide sequence-dependent stalling by perturbing nascent chain-tunnel interactions through P-site tRNA relocation. Steered molecular dynamics simulations provide qualitative support for this model. Together, our findings provide mechanistic insight into a mode of arrest release distinct from the translocon-mediated release mechanism. en-copyright= kn-copyright= en-aut-name=IsoKaishi en-aut-sei=Iso en-aut-mei=Kaishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaToma en-aut-sei=Ikeda en-aut-mei=Toma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamasakiKohei en-aut-sei=Yamasaki en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndoYushin en-aut-sei=Ando en-aut-mei=Yushin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SanoFumiya K. en-aut-sei=Sano en-aut-mei=Fumiya K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FurutaTadaomi en-aut-sei=Furuta en-aut-mei=Tadaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaguchiHideki en-aut-sei=Taguchi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NurekiOsamu en-aut-sei=Nureki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ChadaniYuhei en-aut-sei=Chadani en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ItohYuzuru en-aut-sei=Itoh en-aut-mei=Yuzuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=2 en-affil=School of Life Science and Technology, Institute of Science Tokyo 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=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=6 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=4-5 article-no= start-page=e70061 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Computer‐Aided Sperm Analysis Protocol for Evaluating Sperm Motility in Japanese Medaka en-subtitle= kn-subtitle= en-abstract= kn-abstract=Changes in sperm motility can serve as an early indicator of reproductive effects caused by environmental chemicals or genetic perturbations. However, sperm motility is highly sensitive to external factors such as osmolarity, ionic composition, and the timing of measurement after activation, making it challenging to obtain consistent and reproducible measurements. Here, we present a standardized protocol for assessing sperm motility in Japanese medaka (Oryzias latipes) using a sperm motility analysis system (SMAS), an application for computer-aided sperm motility analysis (CASA). This protocol details the procedures for sperm collection, activation, and quantitative motility assessment, with particular focus on changes in the percentage of motile sperm post activation and the effects of sperm cryopreservation. We demonstrate time-dependent declines in sperm motility and velocity, and highlight the importance of early post-activation measurements to accurately capture peak motility. Notably, cryopreservation significantly accelerated the decline in sperm motility rate without affecting the initial proportion of motile sperm. To enable reliable comparisons among experimental groups, we recommend standardizing the initiation time after sperm activation by using CASA, and show that measurements should be initiated within 1 min after activation to obtain consistent and reliable data. This standardized SMAS-based protocol provides a robust and reproducible framework for sperm motility analysis in medaka and will be valuable not only for studies in reproductive biology, toxicology, and environmental risk assessment but also for applied research, such as breeding of aquacultural fishes. en-copyright= kn-copyright= en-aut-name=KuroyanagiMiwa en-aut-sei=Kuroyanagi en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKeigo en-aut-sei=Okamoto en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatoAi en-aut-sei=Kato en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamazakiTouko en-aut-sei=Yamazaki en-aut-mei=Touko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KameiYasuhiro en-aut-sei=Kamei en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeEiji en-aut-sei=Watanabe en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaruseKiyoshi en-aut-sei=Naruse en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OginoYukiko en-aut-sei=Ogino en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Advanced Aquaculture Science, Faculty of Marine Bioscience and Technology, Fukui Prefectural University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Aquatic Molecular Developmental Biology, Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= affil-num=4 en-affil=Interuniversity Bio-Backup Project Center, National Institute for Basic Biology (NIBB) kn-affil= affil-num=5 en-affil=Laboratory of Bioresources, National Institutes of Natural Sciences kn-affil= affil-num=6 en-affil=Optics and Bioimaging Facility, NIBB kn-affil= affil-num=7 en-affil=Basic Biology Program, Graduate University for Advanced Studies (SOKENDAI) kn-affil= affil-num=8 en-affil=Laboratory of Bioresources, National Institutes of Natural Sciences kn-affil= affil-num=9 en-affil=Laboratory of Aquatic Molecular Developmental Biology, Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= en-keyword=computer-aided sperm motility analysis (CASA) kn-keyword=computer-aided sperm motility analysis (CASA) en-keyword=medaka kn-keyword=medaka en-keyword=sperm motility kn-keyword=sperm motility en-keyword=sperm motility analysis system (SMAS) kn-keyword=sperm motility analysis system (SMAS) END start-ver=1.4 cd-journal=joma no-vol=194 cd-vols= no-issue= article-no= start-page=118923 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elucidation of mechanisms underlying the therapeutic effects of cordycepin on pulmonary hypertension, with a focus on cell senescence and gut microbiota en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Pulmonary hypertension (PH) is a progressive cardiopulmonary disorder characterized by excessive pulmonary vascular remodeling and aberrant proliferation of pulmonary artery smooth muscle cells (PASMCs). Emerging evidence suggests that gut microbiota dysbiosis contributes to PH development. Cordycepin, a natural adenosine analogue derived from Cordyceps militaris, has demonstrated antiproliferative and microbiota-modulating properties; however, its mechanism of action in PH remains unclear.
Objective: Elucidate the mechanisms underlying the therapeutic effects of cordycepin on PH, focusing on cellular senescence and gut microbiota.
Methods: The effects of cordycepin on PH pathology were investigated by transcriptome analysis of PASMCs from patients, and metagenomic analysis of rodent PH models. Cellular senescence was analyzed in lung tissue from p16Ink4a-CreERT2 reporter mice and in rat bone marrow-derived macrophages (BMDMs).
Results: RNA sequencing analysis revealed activation of p53 signaling by cordycepin in PASMCs. Cordycepin suppressed CDK1 expression and TERT phosphorylation at threonine 249. It ameliorated vascular and cardiac remodeling in PH rat and mouse models. Cordycepin induced M1-like macrophage senescence in p16 Ink4a reporter mice lungs and rat BMDMs. Cordycepin significantly reshaped the gut microbiota, increasing beneficial genera (e.g. Alistipes and Acetatifactor) and reducing proinflammatory taxa (e.g., Ruminococcus), with modulating key metabolic pathways, including short-chain fatty acid, tryptophan, and vitamin K2 metabolism.
Conclusion: Cordycepin exerts multi-target therapeutic effects in PH by inhibiting PASMC proliferation via the p53–CDK1/pTERT axis, modulating gut microbiota-linked immunometabolism and induces proinflammatory macrophage senescence. These findings support cordycepin as a promising candidate for PH therapies targeting the vascular, immune, and gut–lung axes. en-copyright= kn-copyright= en-aut-name=LiGaopeng en-aut-sei=Li en-aut-mei=Gaopeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhaoZhixin en-aut-sei=Zhao en-aut-mei=Zhixin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MachitaniMitsuhiro en-aut-sei=Machitani en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikawaRyou en-aut-sei=Ishikawa en-aut-mei=Ryou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshikawaKaori en-aut-sei=Ishikawa en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokotaNaoya en-aut-sei=Yokota en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HabaReiji en-aut-sei=Haba en-aut-mei=Reiji 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=SunZhihong en-aut-sei=Sun en-aut-mei=Zhihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KuraharaLin-Hai en-aut-sei=Kurahara en-aut-mei=Lin-Hai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HiranoKatsuya en-aut-sei=Hirano en-aut-mei=Katsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Inner Mongolia Key Laboratory of Dairy Biotechnology and Engineering, Key Laboratory of Dairy Products Processing, Ministry of Agriculture and Rural Affairs, Key Laboratory of Dairy Biotechnology and Engineering, Ministry of Education, Inner Mongolia Agricultural University kn-affil= affil-num=3 en-affil=Division of Cancer Stem Cell, National Cancer Center Research Institute kn-affil= affil-num=4 en-affil=Department of Diagnostic Pathology, Kagawa University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Kagawa University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery, Faculty of Medicine, Kagawa University kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kagawa University Hospital kn-affil= affil-num=8 en-affil=Center for Advanced Heart Failure, Okayama University Hospital kn-affil= affil-num=9 en-affil=Inner Mongolia Key Laboratory of Dairy Biotechnology and Engineering, Key Laboratory of Dairy Products Processing, Ministry of Agriculture and Rural Affairs, Key Laboratory of Dairy Biotechnology and Engineering, Ministry of Education, Inner Mongolia Agricultural University kn-affil= affil-num=10 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Kagawa University kn-affil= affil-num=11 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Kagawa University kn-affil= en-keyword=Pulmonary hypertension kn-keyword=Pulmonary hypertension en-keyword=p53 kn-keyword=p53 en-keyword=CDK1 kn-keyword=CDK1 en-keyword=TERT kn-keyword=TERT en-keyword=p16 kn-keyword=p16 en-keyword=Microbiota kn-keyword=Microbiota END start-ver=1.4 cd-journal=joma no-vol=208 cd-vols= no-issue=6 article-no= start-page=2124 end-page=2133 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decreased renal function predicts severe cytokine release syndrome after CAR-T-cell therapy for large B-cell lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cytokine release syndrome (CRS) remains a major toxicity of chimeric antigen receptor (CAR) T-cell therapy in large B-cell lymphoma (LBCL), and robust pre-infusion predictors are needed for risk-adapted management. We retrospectively analysed LBCL patients in the Japanese nationwide registry who underwent CD19 CAR-T-cell therapy between 2019 and 2024. Among 900 patients (median age 62 years), cumulative incidences of CRS within 30 days after infusion were 75.0% for any grade, 20.8% for grade ≥ 2 and 14.0% for grade ≥ 3. In multivariable analysis, lower estimated glomerular filtration rate (eGFR) (adjusted hazard ratio [aHR] 1.108 per 10 mL/min per 1.73 m2 decrease; 95% confidence interval [CI] 1.015–1.209; p = 0.022), higher ferritin (aHR 1.006 per 100 ng/mL; 95% CI 1.001–1.010; p = 0.016), C-reactive protein (CRP) (aHR 1.142 per mg/dL; 95% CI 1.091–1.195; p < 0.001) and lactate dehydrogenase (LDH) (aHR 1.073 per 100 U/L; 95% CI 1.008–1.142; p = 0.028) independently predicted grade ≥ 2 CRS. We then built a four-factor CRS pre-infusion risk evaluation model, cytokine release syndrome-pre-infusion risk evaluation (CRS-PRE), that stratified grade ≥ 2 CRS risk into low, intermediate and high groups with incidences of 2.8%, 26.0% and 50.0% respectively. Decreased eGFR, a surrogate of host renal reserve, with elevated ferritin, CRP and LDH emerged as predictors of high-grade CRS. The CRS-PRE may facilitate risk-adapted monitoring and intervention in clinical practice. en-copyright= kn-copyright= en-aut-name=AraiYasuyuki en-aut-sei=Arai en-aut-mei=Yasuyuki kn-aut-name=

findings from surveys of both clients and medical professionals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Online genetic care can offer a promising solution to the shortage of qualified medical professionals in genetic medicine, which leads to regional disparities in access. However, despite global adoption, its use in Japan remains limited.
Methods Two questionnaire surveys were conducted to investigate potential needs and barriers regarding online genetic care: one involving 858 medical professionals (738 physicians and 120 genetic counselors or nurses), and the other involving 443 clients who received in-person genetic counseling.
Results Only 14.0% of the medical professionals had experience with online genetic care, although 85.9% of the professionals engaged in cancer genetics were willing to consider providing it in the future. Notably, a discrepancy was found regarding hospital selection: clients prioritized access to specialized medical care, whereas professionals assumed clients valued accessibility for family members. Professionals expressed greater concerns about adequacy of online communication, client environments and internet security. Among clients, 89.1% estimated they would sufficiently understand and accept total content of counseling session if were conducted online. Older age and infrequent internet use were associated with lower acceptance and higher anxiety regarding online methods. Concerns about ability to use the necessary technology affected clients’ willingness to encourage online care for their relatives.
Conclusion Online genetic care shows high potential for client acceptance and can effectively address regional disparities in Japan. To bridge the gap between client needs and professional perceptions and to overcome the digital divide, it is necessary to develop secure, accessible systems and provide education for both patients and healthcare providers. en-copyright= kn-copyright= en-aut-name=UenoSayaka en-aut-sei=Ueno en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UrakawaYusaku en-aut-sei=Urakawa en-aut-mei=Yusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoFumino en-aut-sei=Kato en-aut-mei=Fumino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UekiArisa en-aut-sei=Ueki en-aut-mei=Arisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanekoKeika en-aut-sei=Kaneko en-aut-mei=Keika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoKoji en-aut-sei=Matsumoto en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugawaraHiromi en-aut-sei=Sugawara en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiSayoko en-aut-sei=Takeuchi en-aut-mei=Sayoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaReiko en-aut-sei=Yoshida en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KakutaMiho en-aut-sei=Kakuta en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkagiKiwamu en-aut-sei=Akagi en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TamuraKazuo en-aut-sei=Tamura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil=Division of Clinical Genetic Oncology, Cancer Institute Hospital, Japanese Foundation for Cancer Research kn-affil= affil-num=5 en-affil=Division of Clinical Genetic Oncology, Cancer Institute Hospital, Japanese Foundation for Cancer Research kn-affil= affil-num=6 en-affil=Division of Clinical Genetics, Hyogo Cancer Center kn-affil= affil-num=7 en-affil=Division of Clinical Genetics, Hyogo Cancer Center kn-affil= affil-num=8 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Medical Genetics and Genomics, Saitama Cancer Center kn-affil= affil-num=10 en-affil=Center for Genomic Diagnosis, International University of Health and Welfare (IUHW) Narita Hospital kn-affil= affil-num=11 en-affil=Center for Genomic Diagnosis, International University of Health and Welfare (IUHW) Narita Hospital kn-affil= affil-num=12 en-affil=Center for Genomic Diagnosis, International University of Health and Welfare (IUHW) Narita Hospital kn-affil= affil-num=13 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Hereditary cancer kn-keyword=Hereditary cancer en-keyword=Remote medical care kn-keyword=Remote medical care en-keyword=Barriers to online genetic care kn-keyword=Barriers to online genetic care en-keyword=Facilitators for online genetic care kn-keyword=Facilitators for online genetic care END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=2 article-no= start-page=25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Machine learning prediction of the Madden–Julian oscillation using reservoir computing en-subtitle= kn-subtitle= en-abstract= kn-abstract=The prediction of the Madden–Julian Oscillation (MJO), a massive tropical weather event with global socio-economic impacts, has been infamously difficult with physics-based weather prediction models. We employ the reservoir computing, a brain-inspired machine-learning technique, to construct a machine learning model that forecasts the real-time multivariate MJO index (RMM), a macroscopic variable that represents the state of the MJO. The training data was refined by development of a novel real-time band-pass filter that extracts the recurrency of MJO signals only from the past raw atmospheric data, and by selection of a suitable time-delay coordinate of the RMM that enhances the recurrency of the input data. The constructed model demonstrated the skill to forecast the time sequence of the RMM for a month from pre-developmental stages of the MJO. Examination of best-performing cases suggested that RMM sequences may be predicted for over two months in some cases. These results imply that inherent predictability limit of the MJO is longer than that has been estimated from physics-based weather prediction models. en-copyright= kn-copyright= en-aut-name=SuematsuTamaki en-aut-sei=Suematsu en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaiKengo en-aut-sei=Nakai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YonedaTsuyoshi en-aut-sei=Yoneda en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasukaDaisuke en-aut-sei=Takasuka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JinnoTakuya en-aut-sei=Jinno en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaikiYoshitaka en-aut-sei=Saiki en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiuraHiroaki en-aut-sei=Miura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=RIKEN Center for Computational Science 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 Economics, Hitotsubashi University kn-affil= affil-num=4 en-affil=Department of Geophysics, Tohoku University kn-affil= affil-num=5 en-affil=Graduate School of Science, The University of Tokyo kn-affil= affil-num=6 en-affil=Graduate School of Business Administration, Hitotsubashi University kn-affil= affil-num=7 en-affil=Graduate School of Science, The University of Tokyo kn-affil= en-keyword=Reservoir computing kn-keyword=Reservoir computing en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Madden–Julian Oscillation kn-keyword=Madden–Julian Oscillation en-keyword=Sub-seasonal forecast kn-keyword=Sub-seasonal forecast END start-ver=1.4 cd-journal=joma no-vol=288 cd-vols= no-issue= article-no= start-page=108478 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hydrogen-lean two-stage upgrading of highly acidic palm acid oil via decoupled acid reduction and deoxygenation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Upgrading highly acidic waste lipids into liquid hydrocarbons under limited hydrogen availability remains challenging due to catalyst deactivation, excessive cracking, and poor process stability. Palm acid oil (PAO), characterized by extremely high free fatty acid content, represents a particularly demanding feedstock. This study proposes a hydrogen-lean two-stage upgrading strategy that decouples acid value (AV) reduction from hydrocarbon formation through staged reactor operation. In the first stage, batch pretreatment under low hydrogen pressure (initial 0.1 MPa) enabled rapid apparent AV reduction. However, increasing temperature promoted thermally driven degradation, highlighting intrinsic limitations of single-stage severity intensification. Methanol-assisted pretreatment further decreased AV mainly through esterification and formation of oxygenated intermediates. In the second stage, hydrogen-free fixed-bed upgrading over oxide-based catalysts exhibited a distinct operating window near 365 °C, where stable condensed liquid recoveries of 50–60 wt% were obtained. Deoxygenation proceeded predominantly via decarbonylation/decarboxylation pathways. Among the catalysts investigated, ZrO₂–Co showed superior stability and lower residual AV. Overall, reactor staging enabled AV reductions exceeding 90% within 1.5–2 h while maintaining stable liquid recovery, demonstrating an effective upgrading strategy for highly acidic waste lipids under hydrogen-lean conditions. en-copyright= kn-copyright= en-aut-name=NogeHirofumi en-aut-sei=Noge en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=UenoYoshie en-aut-sei=Ueno en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YahyaWira Jazair en-aut-sei=Yahya en-aut-mei=Wira Jazair kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Abd KadirHasannuddin en-aut-sei=Abd Kadir en-aut-mei=Hasannuddin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasunagaSachi en-aut-sei=Masunaga en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate school of education, Okayama university kn-affil= affil-num=2 en-affil=Department of comprehensive technical solutions, Okayama University kn-affil= affil-num=3 en-affil=Department of Food and Nutrition, Faculty of Home Economics, Kyoto Women's University kn-affil= affil-num=4 en-affil=Institute for Sustainable Transport HICoE, University Teknologi Malaysia kn-affil= affil-num=5 en-affil=Faculty of Mechanical Engineering, Universiti Teknologi MARA kn-affil= affil-num=6 en-affil=Department of comprehensive technical solutions, Okayama University kn-affil= en-keyword=Palm acid oil kn-keyword=Palm acid oil en-keyword=Two-stage upgrading kn-keyword=Two-stage upgrading en-keyword=Hydrogen-lean deoxygenation kn-keyword=Hydrogen-lean deoxygenation en-keyword=Fixed-bed reactor kn-keyword=Fixed-bed reactor en-keyword=Acid value reduction kn-keyword=Acid value reduction END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue= article-no= start-page=114910 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optical spectroscopic evaluation on the acquisition of optimal sonication temperature for efficient liquid phase exfoliation of molybdenum disulfide en-subtitle= kn-subtitle= en-abstract= kn-abstract=This work investigates how the sonication temperature affects the liquid phase exfoliation of MoS₂ using optical and morphological approach in attempt to acquire an optimal temperature for such process at ambient room conditions. In an ultrasonic bath, exfoliation was carried out at six different temperatures. UV-Vis, FTIR, Raman spectroscopy and SEM characterizations reveal that moderate room temperature range yield excellent results producing well-dispersed flakes with strong excitonic properties with mild oxidation. Higher temperatures cause substantial oxidation, deterioration and restacking while lower temperatures led to insufficient exfoliation and fragmented morphologies because of insufficient cavitation energy. The findings highlight the importance of temperature control in producing high quality nanosheets for scalable applications. en-copyright= kn-copyright= en-aut-name=AbdullahFatimah Az-Zahra Saravanan binti en-aut-sei=Abdullah en-aut-mei=Fatimah Az-Zahra Saravanan binti kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LeeWengnam en-aut-sei=Lee en-aut-mei=Wengnam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ÖhbergPatrik en-aut-sei=Öhberg en-aut-mei=Patrik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GohBoontong en-aut-sei=Goh en-aut-mei=Boontong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChongWuyi en-aut-sei=Chong en-aut-mei=Wuyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AhmadHarith en-aut-sei=Ahmad en-aut-mei=Harith kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=YapYuenkiat en-aut-sei=Yap en-aut-mei=Yuenkiat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=School of Engineering and Physical Sciences, Heriot-Watt University Malaysia kn-affil= affil-num=2 en-affil=Foundation Center, Heriot-Watt University Malaysia kn-affil= affil-num=3 en-affil=Institute of Photonics and Quantum Sciences, School of Engineering and Physical Sciences, Heriot-Watt University kn-affil= affil-num=4 en-affil=Low Dimensional Materials Research Center, Department of Physics, Faculty of Science, University of Malaya kn-affil= affil-num=5 en-affil=Photonics Research Center, University of Malaya kn-affil= affil-num=6 en-affil=Photonics Research Center, University of Malaya kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Foundation Center, Heriot-Watt University Malaysia kn-affil= en-keyword=MoS2 kn-keyword=MoS2 en-keyword=Liquid phase exfoliation kn-keyword=Liquid phase exfoliation en-keyword=Cavitation kn-keyword=Cavitation en-keyword=Oxidation kn-keyword=Oxidation END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=52641 end-page=52653 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Programmable Clock Distribution Using Switching Matrices for Field Programmable Gate Arrays en-subtitle= kn-subtitle= en-abstract= kn-abstract=Every digital systems using very large scale integration require clock distributions, for which a dedicated clock tree or a mesh clock is frequently used. Field programmable gate arrays have numerous general-purpose programmable wires based on switching matrices to connect the outputs and inputs of look-up tables and input–output ports. However, field programmable gate arrays never use numerous general-purpose programmable wires for their clock distributions to satisfy the clock skew margin similarly to very large scale integrations. Field programmable gate arrays also use dedicated clock trees, although their programmability is not high. Currently, field programmable gate arrays can support multiple dedicated clock routing or multiple clock trees. Unfortunately, the number of clock trees is fixed. They remain limited to a small number. Even if an application requires many clock distributions, such a clock distribution cannot be supported in current field programmable gate arrays. This paper therefore presents a proposal of a more flexible clock distribution method based on wiring channels and switching matrices. The method uses general-purpose programmable wires. In addition, to resolve clock skew increase difficulties, we have introduced a new flip-flop with a two-phase clock signal. This paper presents simulation results obtained using the proposed clock distribution method on an originally designed field programmable gate array. In addition, experimentally obtained results indicate that the proposed clock distribution method can function correctly on a Cyclone V field programmable gate array. en-copyright= kn-copyright= en-aut-name=OguraAyumu en-aut-sei=Ogura en-aut-mei=Ayumu 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=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= en-keyword=Clock distribution kn-keyword=Clock distribution en-keyword=field programmable gate array (FPGA) kn-keyword=field programmable gate array (FPGA) en-keyword=programmable device kn-keyword=programmable device en-keyword=two-phase clock kn-keyword=two-phase clock END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=3 article-no= start-page=496 end-page=502 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bortezomib Induces Apoptosis via Upregulation of Abhd4 in Peripheral Nerve Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bortezomib, a first-in-class proteasome inhibitor, is widely used to treat multiple myeloma and other hematological malignancies. Despite its therapeutic efficacy, bortezomib causes peripheral neuropathy (PN) in approximately 20–30% of patients, often leading to dose reduction or discontinuation. Preventive or therapeutic approaches to bortezomib-induced PN are currently unavailable, as its precise mechanism remains unclear. In this study, we compared the effects of bortezomib and the second-generation proteasome inhibitor carfilzomib on peripheral nerve cells to identify candidate molecules involved in PN development. Transcriptome profiling of differentiated F11 cells, a hybridoma of a rat embryonic dorsal root ganglion and mouse neuroblastoma cell line N18TG2, revealed that bortezomib selectively upregulated α/β-hydrolase containing domain 4 (Abhd4), whereas carfilzomib did not. This finding was confirmed by quantitative RT-PCR and immunoblotting, which demonstrated consistent increases in Abhd4 mRNA and protein levels following bortezomib treatment. Functional analysis further revealed that Abhd4 overexpression promoted early apoptosis, suggesting a mechanistic link between bortezomib-induced Abhd4 elevation and neuronal vulnerability. Therefore, these results suggest that Abhd4 represents a candidate molecular signature associated with bortezomib-induced PN. Although further in vivo validation is needed, these findings warrant further investigation of Abhd4 as a potential contributor to bortezomib-induced PN. en-copyright= kn-copyright= en-aut-name=KonishiYusuke en-aut-sei=Konishi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmuraTomohiro en-aut-sei=Omura en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IjichiTakeshi en-aut-sei=Ijichi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiguchiHiroki en-aut-sei=Nishiguchi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayakawaRyunosuke en-aut-sei=Hayakawa en-aut-mei=Ryunosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitahiroYumi en-aut-sei=Kitahiro en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoharaKotaro en-aut-sei=Itohara en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoKazuhiro en-aut-sei=Yamamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanoIkuko en-aut-sei=Yano en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=2 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=5 en-affil=Education and Research Center for Clinical Pharmacy, Kobe Pharmaceutical University kn-affil= affil-num=6 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=8 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= en-keyword=bortezomib kn-keyword=bortezomib en-keyword=carfilzomib kn-keyword=carfilzomib en-keyword=peripheral neuropathy kn-keyword=peripheral neuropathy en-keyword=multiple myeloma kn-keyword=multiple myeloma en-keyword=proteasome inhibitor kn-keyword=proteasome inhibitor END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=5 article-no= start-page=e70314 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Survey to Document the Adverse Reactions After Human Papillomavirus Vaccination Among Japanese Female Youth at a University en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Concerns about possible adverse events remain a critical barrier in implementing human papillomavirus (HPV) vaccination among Japanese youth. This study aimed to understand the time course of adverse events experienced by HPV vaccine recipients.
Methods: An online questionnaire survey was given to students, faculty, and staff aged 18–26 years, at Okayama University Hospital, who received the HPV vaccine. The survey gathered information on the number of HPV vaccine doses received, prevaccination health conditions, adverse reactions within 2 h and between 2 h and 7 days postvaccination, menstrual irregularities after vaccination, reasons for getting vaccinated, feelings before and after vaccination, and factors providing reassurance during vaccination. Prevalence of symptoms was expressed as numbers and percentages, and analyses were performed using Chi-squared or Fisher's exact tests.
Results: Responses were obtained from 299 participants, yielding a 75% response rate. Approximately 60% participants reported local pain, 30% swelling, and 4% fever. Most symptoms resolved on the vaccination day itself or the following day, although some persisted for 3–7 days. Over 80% participants rated their pain between 0 and 3 on numerical rating scale of 0–10. While 60% experienced anxiety before vaccination, 90% reported no anxiety afterward.
Conclusions: Our study presents one of the first comprehensive accounts of post-HPV vaccination adverse events and their time course, and underpins the importance of disseminating detailed information about vaccine-associated adverse reactions to encourage greater vaccine uptake. en-copyright= kn-copyright= en-aut-name=HiguchiChigusa en-aut-sei=Higuchi en-aut-mei=Chigusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaChikako en-aut-sei=Ogawa en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwasakiYoshiaki en-aut-sei=Iwasaki en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Educational and Research Management Field, Health Management Department, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=1Educational and Research Management Field, Health Management Department, Okayama University kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=human papillomavirus vaccine kn-keyword=human papillomavirus vaccine en-keyword=Japanese youth kn-keyword=Japanese youth en-keyword=questionnaire kn-keyword=questionnaire en-keyword=survey kn-keyword=survey END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=1612 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Community health worker-supported oral health promotion in low- and middle-income countries: a scoping review of roles, interventions, and outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Oral diseases are among the most prevalent conditions worldwide and disproportionately affect populations in low- and middle-income countries (LMICs). The shortage and maldistribution of the oral health workforce have widened inequalities in prevention and treatment. Task-sharing through community health workers (CHWs) has been promoted as a cost-effective and sustainable strategy for extending services to underserved populations; however, evidence on their roles in oral health promotion in LMICs remains fragmented. This scoping review mapped evidence on CHW-supported oral health promotion and identified common roles, interventions, and system-level challenges.
Methods A comprehensive search was conducted in PubMed, CINAHL, CENTRAL, and Google Scholar, using keywords and MeSH terms related to “community health workers,” “oral health,” and LMICs, based on the EPOC LMIC filter of the World Bank’s classifications. No publication date restrictions were applied, and gray literature was included. The review followed the Joanna Briggs Institute (JBI) methodology for scoping reviews and was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Data were charted on CHW characteristics, roles, target populations, oral conditions addressed, and implementation challenges, and synthesized narratively. This protocol was registered on Open Science Forum (https://doi.org/10.17605/OSF.IO/NZPHA).
Results Thirty-two studies from 11 LMICs were included, approximately half from India. The evidence mapped a wide range of CHW roles and interventions, most commonly focusing on oral cancer screening, followed by dental caries prevention and periodontal care. CHWs were involved in home visits, education, screening, basic treatment, and referrals. Some programs integrate mobile health (mHealth) tools for remote diagnosis. System-level challenges were variably reported across settings, including inadequate infrastructure, fragmented referral systems, limited supervision, and constrained career development opportunities for CHWs.
Conclusions This scoping review highlights the contributions of CHWs to oral health promotion in LMICs, while underscoring health system and workforce constraints. The available evidence is largely descriptive, suggesting the need for strengthened training, supervision, referral linkages, and career development to support CHWs’ integration into oral health services. Family-centered and Continuum of Care approaches warrant further exploration to inform equitable and sustainable oral health within primary health care systems. en-copyright= kn-copyright= en-aut-name=YasuokaJunko en-aut-sei=Yasuoka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Division of Global Health Sciences, Graduate School of Public Health, St. Luke’s International University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Community health worker kn-keyword=Community health worker en-keyword=Oral health kn-keyword=Oral health en-keyword=Low- and middle-income countries kn-keyword=Low- and middle-income countries END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proposing an alternative direction for the development of research: a complementary perspective on Schoenfeld’s approach to generality en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to propose a theoretical framework that suggests directions for future research. While Schoenfeld’s three-axis heuristic framework is well known for this purpose, it primarily points toward increasing generality. Drawing on prior studies on the generalizability of empirical findings in educational research, this paper argues that an alternative research path is possible. Building on the distinction between prevalence and scope, it proposes two types of generality: the generality of a phenomenon within a specified scope and the generality of a theory. Correspondingly, it identifies two directions for research development: delimitation of the scope and generalization of a theory. Finally, the paper argues that research development based on this framework can be understood as progressive in the Lakatosian sense. While Schoenfeld’s framework suggests directions for individual studies, this framework guides competing research programmes by enabling both to progress through scope delimitation. en-copyright= kn-copyright= en-aut-name=UegataniYusuke en-aut-sei=Uegatani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshibashiIppo en-aut-sei=Ishibashi en-aut-mei=Ippo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Hiroshima University High School kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= en-keyword=Schoenfeld’s heuristic framework for situating research studies kn-keyword=Schoenfeld’s heuristic framework for situating research studies en-keyword=prevalence kn-keyword=prevalence en-keyword=generality kn-keyword=generality en-keyword=scope kn-keyword=scope en-keyword=delimitation of scope kn-keyword=delimitation of scope END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=2 article-no= start-page=18 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-pressure spectroscopic investigation of ε-FeOOH: toward a better understanding of pressure-induced hydrogen-bond symmetrization en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-pressure spectroscopic measurements of ε-FeOOH were conducted up to ~ 65 GPa at room temperature in diamond anvil cells. The pressure evolution of the Raman vibrational modes confirms that a hydrogen-bond-symmetrization-induced phase transition from P21nm to Pnnm occurs at ~ 18 GPa. Infrared (IR) spectroscopic measurements suggest that the Pnnm phase has a disordered hydrogen state, and no spectroscopic evidence for fully centered hydrogen bonds is observed within the investigated pressure range. Above ~ 45 GPa, Fe3+ in ε-FeOOH undergoes a high-spin to low-spin transition as indicated by a reduction of the unit cell volume, together with reductions in IR transmitted and Raman signals. These results demonstrate that ε‑FeOOH preserves a disordered hydrogen‑bond configuration up to at least 45 GPa, whereas δ-AlOOH transforms to a centered hydrogen-bond configuration at ~ 18 GPa. This compositional contrast suggests that Fe‑bearing oxyhydroxides follow a distinct evolution of hydrogen bonding under compression, providing insight into hydrogen behavior in deep Earth materials. en-copyright= kn-copyright= en-aut-name=MashinoIzumi en-aut-sei=Mashino en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaShigeru en-aut-sei=Yamashita en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=ε-FeOOH kn-keyword=ε-FeOOH en-keyword=High pressure kn-keyword=High pressure en-keyword=Spin transition kn-keyword=Spin transition en-keyword=Hydrogen bond symmetrization kn-keyword=Hydrogen bond symmetrization END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=3 article-no= start-page=e113430 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Protocol for an open-label, randomised, controlled trial to evaluate the efficacy and safety of sotatercept add-on therapy compared with pulmonary vasodilator-based standard of care for pulmonary vasodilator-resistant pulmonary arterial hypertension associated with unrepaired congenital shunts (atrial septal defect, ventricular septal defect or patent ductus arteriosus), including Eisenmenger syndrome: the SuMILE trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Eisenmenger syndrome and pulmonary arterial hypertension (PAH) due to unrepaired congenital shunts, including atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA), remain life-threatening conditions despite advances in congenital heart disease (CHD) care. In this population, vasodilator-based therapies effective in other forms of PAH have shown limited benefit, and no disease-modifying treatment has been established. Sotatercept, an activin-signalling inhibitor, improved exercise capacity and haemodynamics in phase 2/3 PAH trials; however, patients with unrepaired CHD, including Eisenmenger syndrome, were excluded. The efficacy and safety of sotatercept in this population remain unknown.
Methods and analysis The SuMILE trial is a prospective, exploratory, multicentre, open-label, randomised, controlled trial conducted at 11 Japanese tertiary centres. 36 adults with vasodilator-resistant PAH due to unrepaired ASD, VSD or PDA, including Eisenmenger syndrome, will be randomised 2:1 to sotatercept add-on therapy plus vasodilator-based PAH therapy versus vasodilator-based PAH therapy alone. Sotatercept will be administered subcutaneously every 3 weeks in accordance with label-approved dose-modification rules for haemoglobin and platelet changes. The primary endpoint is the change in 6-min walk distance from baseline to week 24. Key clinical events will be independently adjudicated. Secondary endpoints include all-cause mortality or lung transplantation; pulmonary hypertension-related hospitalisation or initiation of parenteral prostacyclin and changes in WHO functional class, N-terminal pro-brain natriuretic peptide and emPHasis-10. Exploratory endpoints include genotype, right heart catheterisation and cardiac MRI parameters. The primary analysis will use ANCOVA, adjusting for baseline 6-min walk distance and randomisation stratum in the intention-to-treat population.
Ethics and dissemination The protocol has been reviewed and approved by the certified central review board (Kyushu University Hospital Clinical Ethics Review Board) and participating institutions. Written informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed journals, scientific conferences and trial registries.

kn-title=PPy-coated wire actuators for micromechanostimulation of cells – identification of immediate-early responsive mechanoregulatory genes in osteoblasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mechanotransduction, i.e., the conversion of mechanical cues into biochemical signals, is essential for bone development, remodeling, and adaptation. Although mechanical loading is known to regulate osteoblast function and bone homeostasis, dissecting the early and sustained mechanotransductive responses at the microscale remains challenging due to limitations of existing in vitro models. Here, we report the development and application of a mechanostimulation system comprising a polypyrrole (PPy)-based wire actuator that expands and contracts (4 μm in radius) upon electrical actuation and enables precise, localized micromechanical stimulation of a small number of cells within standard culture formats. Using this system, we applied short-term (30 min) cyclic (Cyc30) or static (Stat30), as well as prolonged (120 min) cyclic (Cyc120) stimulations to two osteoblast-like cells (MC3T3-E1 or KUSA-A1). Subsequent transcriptomic profiling and computational network analyses revealed that Cyc30 was not capable of inducing significant changes in mRNA expression, suggesting cellular adaptation to short-term cyclic loading. In contrast, Stat30 induced the upregulation of Fos, Btg2, Egr1, and Fosl1, all known genes associated with mechanotransduction, supporting the validity and reproducibility of our experimental mechanostimulation system. Notably, two long non-coding RNAs (B930036N10Rik and 5430431A17Rik) were identified for the first time as being upregulated in response to Stat30 stimuli. Among the differentially expressed genes (DEGs) upregulated by Cyc120 stimuli, Hmox1, a stress-inducible enzyme known for its roles in maintaining cellular homeostasis and promoting survival, was the only DEG repeatedly observed across the Cyc30/Cyc120 and Stat30/Cyc120 comparisons in both cell types, potentially emerging as a key stress-response gene under prolonged mechanical loading. Collectively, these results establish the PPy-based microactuator as a powerful tool for microscale mechanobiology, and provide molecular insight into immediate-early responsive transcriptional programs underlying osteoblastic mechanoadaptation conserved across different cell types. en-copyright= kn-copyright= en-aut-name=ChenJiamin en-aut-sei=Chen en-aut-mei=Jiamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Ortega-SantosAmaia B. en-aut-sei=Ortega-Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MartinezJose G. en-aut-sei=Martinez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=JagerEdwin W.H. en-aut-sei=Jager en-aut-mei=Edwin W.H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Physics, Chemistry and Biology (IFM), Linköping University kn-affil= affil-num=3 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Physics, Chemistry and Biology (IFM), Linköping University kn-affil= affil-num=6 en-affil=Department of Advanced International and Information Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Physics, Chemistry and Biology (IFM), Linköping University kn-affil= affil-num=8 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Mechanotransduction kn-keyword=Mechanotransduction en-keyword=Mechanostimulation kn-keyword=Mechanostimulation en-keyword=Osteoblasts kn-keyword=Osteoblasts en-keyword=Polypyrrole kn-keyword=Polypyrrole 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=2026 dt-pub=20260511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative study of Ni–CeO2 catalysts prepared by impregnation and coprecipitation for CO2 methanation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explores how synthesis methods affect the structure and CO2 methanation performance of Ni–CeO2 catalysts prepared by coprecipitation and impregnation under identical conditions. Coprecipitation generated particles below 100 nm with uniform elemental distribution, together with large bulk-like particles exhibiting locally concentrated Ni species, attributed to differences in hydroxide solubility. Impregnation, by contrast, produced very large particles (> 500 nm) with smaller particles attached, while maintaining relatively homogeneous elemental distribution. Coprecipitated catalysts showed slightly higher surface area and oxygen vacancy concentration, resulting in higher apparent turnover frequencies (TOFapp) below 300 °C due to enhanced CO2 adsorption and high Ni site density. However, at temperatures above 350 °C, impregnated catalysts displayed higher CH4 selectivity and TOFapp, indicating reduced kinetic limitations and more efficient active-site utilization. These results provide insights for rational design of efficient CO2 methanation catalysts. en-copyright= kn-copyright= en-aut-name=FukudaNobuko en-aut-sei=Fukuda en-aut-mei=Nobuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImanoShuichi en-aut-sei=Imano en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaharaNozomi en-aut-sei=Nakahara en-aut-mei=Nozomi 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=27 cd-vols= no-issue=5 article-no= start-page=e2026GC012945 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chemical Geodynamics of Granitoid Magmatism During a Pacific‐Philippine Sea Plate Transition in Southwest Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granitoid magmatism along the western Pacific margin records interactions between subduction dynamics and crust–mantle processes; however, the links between plate reorganization and magma-source evolution remain debated. Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene granitoids in Southwest Japan. Zircon U–Pb ages define two discrete magmatic episodes at 110–60 Ma and 45–30 Ma, separated by a magmatic hiatus of ∼10–15 Myr. These granitoid groups exhibit distinct isotopic signatures, indicating derivation from isotopically distinct magma sources linked to the paleo-Pacific (Izanagi) plate and the Philippine Sea plate, respectively. Isotope-based mass-balance modeling indicates higher sediment contributions to the older granitoids, with decreasing sediment input both landward and through time. The magmatic lull at ca. 52–40 Ma coincides with an abrupt isotopic shift and is interpreted to reflect plate reorganization, during which subduction of the paleo-Pacific plate was replaced by a transform or highly oblique plate boundary associated with the northward migration of the proto–Philippine Sea plate. Independent constraints from convergence rates, sediment flux, and accretionary complex development support this interpretation. These results demonstrate that granitoid magmatism in Southwest Japan was fundamentally controlled by temporal changes in subducted lithosphere and sediment flux driven by plate reorganization, highlighting the sensitivity of arc magmatism to transient tectonic regimes. en-copyright= kn-copyright= en-aut-name=DaoNghiem V. en-aut-sei=Dao en-aut-mei=Nghiem V. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YemerTsegereda A. en-aut-sei=Yemer en-aut-mei=Tsegereda A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MwaisubaTulibako T. en-aut-sei=Mwaisuba en-aut-mei=Tulibako T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaguchiChie en-aut-sei=Sakaguchi en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KobayashiKatsura en-aut-sei=Kobayashi en-aut-mei=Katsura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ImaokaTeruyoshi en-aut-sei=Imaoka en-aut-mei=Teruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=3 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=4 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=5 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=6 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=7 en-affil=Division of Earth Science, Graduate School of Sciences and Technology for Innovation, Yamaguchi University kn-affil= affil-num=8 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= en-keyword=granitoids kn-keyword=granitoids en-keyword=Pb–Sr–Nd–Hf isotopes kn-keyword=Pb–Sr–Nd–Hf isotopes en-keyword=Pacific-Philippine Sea plates kn-keyword=Pacific-Philippine Sea plates en-keyword=sub-crustal origin kn-keyword=sub-crustal origin en-keyword=tectonic transition kn-keyword=tectonic transition END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue=8 article-no= start-page=595 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Basin boundary metamorphoses due to changes in accessible boundary orbits in passive dynamic walking en-subtitle= kn-subtitle= en-abstract= kn-abstract=Passive dynamic walking is a mechanical system that walks down a shallow slope without any input or control, and is a useful tool for understanding the dynamic properties of walking. This system has a wide variety of periodic solutions through bifurcations depending on the slope angle, resulting in chaotic attractors and fractal basin boundaries. In addition, basin boundary metamorphoses occur at certain slope angles, where the boundaries of the basin of attraction change abruptly, but the mechanism underlying this phenomenon remains largely unclear. A well-known dynamical system, the Hénon map, exhibits similar properties, and its basin boundary metamorphoses have been explained in terms of changes in accessible boundary orbits caused by intersections of manifolds associated with bifurcating solutions. Inspired by this framework, we propose a hypothesis for the mechanism of basin boundary metamorphoses in passive dynamic walking by introducing the concept of accessible boundary orbits and verify it numerically. Our results provide new insights into the governing dynamics of walking and contribute to a deeper understanding of nonlinear phenomena in locomotion systems. en-copyright= kn-copyright= en-aut-name=OkamotoKota en-aut-sei=Okamoto en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkashiNozomi en-aut-sei=Akashi en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KokubuHiroshi en-aut-sei=Kokubu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorkeJames A. en-aut-sei=Yorke en-aut-mei=James A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoiShinya en-aut-sei=Aoi en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Aeronautics and Astronautics, Graduate School of Engineering, Kyoto University kn-affil= affil-num=2 en-affil=Graduate School of Informatics, Kyoto University kn-affil= affil-num=3 en-affil=nterdisciplinary Education and Research Field, Okayama University kn-affil= affil-num=4 en-affil=Department of Mathematics, Graduate School of Science, Kyoto University kn-affil= affil-num=5 en-affil=Departments of Mathematics and Physics, Institute for Physical Science and Technology, University of Maryland kn-affil= affil-num=6 en-affil=Department of Mechanical Science and Bioengineering, Graduate School of Engineering Science, The University of Osaka kn-affil= en-keyword=Passive dynamic walking kn-keyword=Passive dynamic walking en-keyword=Basin boundarymetamorphoses kn-keyword=Basin boundarymetamorphoses en-keyword=Accessible boundary orbit kn-keyword=Accessible boundary orbit en-keyword=Saddle-node bifurcation kn-keyword=Saddle-node bifurcation en-keyword=Homoclinic and heteroclinic intersections kn-keyword=Homoclinic and heteroclinic intersections END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=12889 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Explainable analysis of the complex maze magnetic domain structure through extension of the Landau free energy model by adding an entropy feature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Maze magnetic domains exhibit complex, temperature-dependent behavior that impacts energy loss in soft magnets, yet their magnetization reversal mechanisms remain poorly understood due to current model limitations. To address this gap, we develop an entropy-extended Landau free energy model that incorporates thermal effects into the analysis of magnetic domain. We employ a data-driven pipeline combining persistent homology, energy decomposition, and principal component analysis to construct an interpretable model that quantifies structure–property relationships and enables causal analysis of magnetic pattern formation. Using this approach, we trace entropy increases to their origins in initial domain configurations and quantify energy transfer among entropic, demagnetization, and exchange contributions. We also find that domain wall lengthening tracks increasing structural complexity, yielding previously inaccessible insights into magnetization reversal mechanism and enabling automated visualization. Our entropy-augmented model provides an explainable framework to decipher magnetization processes and guide the design of magnetic materials to reduce energy loss. en-copyright= kn-copyright= en-aut-name=MasuzawaK. en-aut-sei=Masuzawa en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FoggiattoA.

In this study, we sought to investigate the phenotypic and genotypic characteristics of S. enterica isolated from the cancer patients admitted at the Tata Medical Center, Kolkata over a period of eight years (2016–2023).
Methods Salmonella enterica isolates were identified by standard biochemical and serotyping. Antimicrobial susceptibility was tested by disk diffusion method and virulence genes were identified by PCR. The genetic relatedness of strains was determined by pulsed-field gel electrophoresis (PFGE) methods.
Results A total of 122 S. enterica isolates were identified and classified into 18 different serovars. S. Typhimurium (28.7%), S. Kentucky (22.1%), S. Enteritidis (13.9%), S. Typhi (5.7%) and S. Agona (5.7%) were identified as the common serovars. S. enterica infection was more often detected in adults (77.9%) than in children of 6–18 years old (11.4%) and < 5 years of age (10.6%). The maximum number of S. enterica was isolated from blood (52.4%) followed by those isolated from stool (36.9%) and urine (5.7%). S. enterica infections were detected among patients with chronic myelogenous leukemia (CML)/acute lymphoblastic leukemia (ALL) (24.6%) than Hodgkin lymphoma/non-Hodgkin lymphoma (16.4%), multiple myeloma (9.8%), lung adenocarcinoma (9%), prostate adenocarcinoma (6.6%), and endometrium carcinoma (5.7%). S. Kentucky showed a statistically significant association with hematologic malignancies (p < 0.001), whereas S. Enteritidis was significantly present in Hodgkin lymphoma and acute lymphoblastic leukemia/Chronic myelogenous leukemia cancer types (p = 0.004). Most of the S. enterica isolates displayed resistance to erythromycin (62.9%), nalidixic acid (62.9%) and tetracycline (33.9%). Salmonella pathogenicity island (SPI)-associated genes (orgA, ssaQ, misL, invE/A, spi4D, pipA and ttrc) were uniformly present in majority of the isolates. The hyper invasive locus (hilA), Salmonella enterotoxin (stn), Salmonella outer protein (sopB), virulence plasmid (spvC), and plasmid encoded fimbriae (pefA) genes were present in 76%, 69%, 51%, 32% and 17% of the isolates, respectively. Clonal analysis of the representative homologous serovars using pulsed-field gel electrophoresis revealed specific clusters with 40 to 90% similarity within each serotype.
Conclusions Cancer patients are at increased risk of morbidity due to secondary infections, like S. enterica. Continuous monitoring of antimicrobial resistance patterns and virulence gene profiles in S. enterica isolates from this vulnerable group is critical to guide clinical management and treatment strategies. en-copyright= kn-copyright= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BhattacharyaSanjay en-aut-sei=Bhattacharya en-aut-mei=Sanjay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GoelGaurav en-aut-sei=Goel en-aut-mei=Gaurav kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChatterjiSoumyadip en-aut-sei=Chatterji en-aut-mei=Soumyadip kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LewisMelissa Glenda en-aut-sei=Lewis en-aut-mei=Melissa Glenda kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR- NICED kn-affil= affil-num=2 en-affil=Tata Medical Center kn-affil= affil-num=3 en-affil=Tata Medical Center kn-affil= affil-num=4 en-affil=Tata Medical Center kn-affil= affil-num=5 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR- NICED kn-affil= affil-num=6 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR- NICED kn-affil= affil-num=7 en-affil=Division of Biostatistics, ICMR - National Institute for Research in Bacterial Infections kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Division of Bacteriology, ICMR - National Institute for Research in Bacterial Infections kn-affil= affil-num=10 en-affil=Division of Bacteriology, ICMR - National Institute for Research in Bacterial Infections kn-affil= en-keyword=Salmonella enterica kn-keyword=Salmonella enterica en-keyword=Cancer kn-keyword=Cancer en-keyword=Virulence kn-keyword=Virulence en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=PFGE kn-keyword=PFGE END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=153 end-page=157 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Revisiting Adrenal Crisis Triggered by Influenza Infection: Lessons from Two Fatal Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Adrenal crisis is a life-threatening endocrine emergency that can progress within hours despite a prior diagnosis and maintenance therapy.

These cases highlight the fulminant course of an adrenal crisis and underscore the importance of early recognition, clinician awareness, prompt parenteral hydrocortisone administration, and reinforcement of education for patients, caregivers, and healthcare providers to improve preparedness and prevent avoidable deaths. en-copyright= kn-copyright= en-aut-name=UedaYoshiyuki en-aut-sei=Ueda en-aut-mei=Yoshiyuki 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=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=adrenal insufficiency kn-keyword=adrenal insufficiency en-keyword=cardiac arrest kn-keyword=cardiac arrest en-keyword=hydrocortisone kn-keyword=hydrocortisone en-keyword=influenza kn-keyword=influenza en-keyword=shock kn-keyword=shock END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=109 end-page=117 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Mixed-Methods Study on Changes in Interprofessional Education Attitudes and Fundamental Competencies: A Pre–Post Analysis of Clinical Training in Dietetic Students en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the effects of interprofessional education (IPE) on dietetics students during clinical training, focusing on changes in their attitudes toward IPE and their fundamental competencies. Eighty third-year female students (mean age, 21.0 years) at a Japanese women’s university participated. Self-administered surveys were conducted before and after clinical training to assess attitudes toward IPE using the Readiness for Interprofessional Learning Scale (RIPLS) and the Shakaijin Kisoryoku (SKL; Fundamental Competencies for Working Persons) scale. Quantitative data were analyzed using paired t-tests, chi-squared tests, and cluster analyses. Qualitative data from open-ended responses were analyzed thematically. RIPLS and SKL scores increased significantly, from 65.3 to 68.9, and from 28. 4 to 33. 2, respectively (p<0.001). All 12 SKL items showed significant improvement. In free responses, “initiative” (66 mentions), “communication” (10), and “execution” (8) were the most frequently cited as improved competencies. Cluster analysis identified three groups: increasing scores (n=25), high baseline (n=30), and minimal change (n=25). No significant correlation was found between changes in RIPLS and SKL scores (r=−0.108, p=0.355). IPE integrated into clinical training may enhance dietetics students’ attitudes toward interprofessional collaboration and contribute to the development of professional identity. Individualized, phased IPE implementation is recommended to accommodate differences in learner readiness. en-copyright= kn-copyright= en-aut-name=SonoiMika en-aut-sei=Sonoi en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SonoiNorihiro en-aut-sei=Sonoi en-aut-mei=Norihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoyamaYoko en-aut-sei=Koyama en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Foods and Human Nutrition, Faculty of Human Life Sciences, Notre Dame Seishin University kn-affil= affil-num=2 en-affil=Center for Education in Medicine and Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Foods and Human Nutrition, Faculty of Human Life Sciences, Notre Dame Seishin University kn-affil= en-keyword=interprofessional education kn-keyword=interprofessional education en-keyword=dietetics students kn-keyword=dietetics students en-keyword=clinical training kn-keyword=clinical training en-keyword=professional competencies kn-keyword=professional competencies en-keyword=transformative learning kn-keyword=transformative learning END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=5 article-no= start-page=2741 end-page=2748 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global trends in systemic sclerosis-related mortality, 2001–2023: an epidemiological analysis using World Health Organization mortality data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives This study aimed to evaluate the global trends in systemic sclerosis (SSc)-related mortality by age, sex, and geographic region. SSc is a multisystem autoimmune disease characterized by tissue fibrosis, vascular dysfunction, and multi-organ involvement, which is associated with a high mortality risk.
Methods Using the World Health Organization Mortality Database, we examined trends in SSc-related crude mortality rates (SSc-CRs) and age-standardized mortality rates (SSc-ASMR) per 1,000,000 population from 2001 to 2023. Locally weighted regression was applied to visualize long-term patterns, and Joinpoint regression was used to assess the national trends from 2010 to 2023.
Results Across 74 countries, 85,291 SSc-related deaths were reported, with 79.41% occurring in females. The SSc-CR steadily increased from 1.97 (95% confidence interval [CI]: 1.71–2.23) in 2001 to 2.34 (95% CI: 2.01–2.68) in 2023, while the SSc-ASMR decreased from 1.58 (95% CI: 1.42–1.74) to 1.29 (95% CI: 1.08–1.50), respectively. Regionally, mortality was the highest in the Western Pacific region and declined in the Americas and Europe, with temporal fluctuations. The SSc-ASMR was highest in countries with a middle sociodemographic index (SDI).
Conclusions While overall age-standardized mortality from SSc has declined in many regions, disparities persist. These results underscore the importance of sustaining research and enhancing disease awareness, as well as developing strategies to reduce mortality in high-risk populations and regions. en-copyright= kn-copyright= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LescanoJudah Israel Ong en-aut-sei=Lescano en-aut-mei=Judah Israel Ong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMichio en-aut-sei=Yamamoto en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Haematology and Oncology, Mayo Clinic, Rochester kn-affil= affil-num=3 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Human Sciences, The University of Osaka kn-affil= affil-num=9 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= en-keyword=Age-standardized mortality rate kn-keyword=Age-standardized mortality rate en-keyword=Global health kn-keyword=Global health en-keyword=Mortality trends kn-keyword=Mortality trends en-keyword=Sociodemographic index kn-keyword=Sociodemographic index en-keyword=Systemic sclerosis kn-keyword=Systemic sclerosis 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=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Triangulation in teaching probability: teaching materials for the theoretical foundations of probability in real-world applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes using the concept of triangulation with probabilistic models as a means to enhance theoretical inversion for deepening students’ understanding of the nature of probability in real-world contexts. Triangulation refers to the combined application of multiple methodologies to investigate the same phenomenon, particularly in the social sciences. Theoretical inversion refers to a shift in focus from surprising outcomes to the theoretical foundations of probability. The paper introduces three types of problem-solving tasks designed to enhance one of four types of triangulations: theory triangulation. Theoretical inversion is expected to emerge through engaging in these tasks. The characteristics of the problems are as follows. Problem 1 promotes students to compare different probabilistic models of events under similar procedures. Problem 2 provides students with an opportunity to simplify an experiment by omitting steps that add no new information. Problem 3 enhances students’ ability to recognise how subtle differences in the experimental setup can affect the resulting probability. These tasks are designed to encourage students to view probabilistic reasoning as a form of modelling and to appreciate the importance of assumptions, definitions of elementary events, and clarity in procedural descriptions. en-copyright= kn-copyright= en-aut-name=UegataniYusuke en-aut-sei=Uegatani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshibashiIppo en-aut-sei=Ishibashi en-aut-mei=Ippo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakotaAya en-aut-sei=Sakota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Hiroshima University High School kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=3 en-affil=Hiroshima University High School kn-affil= en-keyword=Probability kn-keyword=Probability en-keyword=triangulation kn-keyword=triangulation en-keyword=mathematical modelling kn-keyword=mathematical modelling en-keyword=theoretical inversion kn-keyword=theoretical inversion END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue= article-no= start-page=24 end-page=33 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= kn-title=算数科「部分に対する部分の割合に当たる大きさ」の問題解決のための足場がけ en-subtitle= kn-subtitle= en-abstract= kn-abstract=　小学５年生向けの一部の算数科教科書では，部分に対する部分の割合に当たる大きさを求める問題が扱われている．しかし，その問題解決は小学５年生には容易ではないと考えられる．そこで本稿は，どのような支援が部分に対する部分の割合に当たる大きさを求める問題解決に有効であるかを明らかにすることを目的とした．足場がけ (Scaffolding) を理論的枠組みとして，具体的な足場がけを構想し，授業を実践した．その結果，「学習者の頭の中で体験的にリアルな問題となるよう問題を工夫すること」，「児童にアイデアの一部 (どのような図的表現を用いたか) を紹介させること」，「図的表現を用いるよう促すこと」，「児童の必要感に応じて，ペアや小グループで互いの問題解決を見せ合うこと」，「児童が教室全体で自身の問題解決を発表すること」，「教師が問題文のどの情報に注目すべきかを指示すること」，「児童が他の児童に問題解決の達成を目指した説明をすること」が，有効な足場がけであることが示唆された．そして，それらの足場がけは，関わり合い機能させることが有効な場合もあることが示唆された． en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=石橋一昴 kn-aut-sei=石橋 kn-aut-mei=一昴 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院教育学域 en-keyword=図式 kn-keyword=図式 en-keyword=現実的数学教育 kn-keyword=現実的数学教育 en-keyword=学習者主体 kn-keyword=学習者主体 en-keyword=小学校 kn-keyword=小学校 en-keyword=統計 kn-keyword=統計 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学教育推進機構 教師教育開発センター原稿執筆要領 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学教育推進機構 教師教育開発センターの活動状況の概要 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=253 end-page=266 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=How Can School Counselors Contribute to Developmentally Supportive Student Guidance: An Examination of Support Expansion Through the Use of Planning Sheets kn-title=スクールカウンセラーは発達支持的生徒指導へいかに貢献できるか ―プランニングシートの活用を通した支援の拡充に向けた検討― en-subtitle= kn-subtitle= en-abstract=　In the revised Guidelines for Student Guidance (2022), the importance of developmentally supportive student guidance, which aims to foster the growth of all students, is clearly emphasized. However, many challenges to its implementation have been identified in school settings, including teachers’ excessive workload and insufficient organizational support systems. Moreover, the support provided by school counselors (SCs) has not yet been sufficiently developed. Therefore, this study examined the potential for expanding SCs’ support in developmentally supportive student guidance by reviewing its current status and challenges. Furthermore, through a reanalysis of a practical case using the Planning Sheet (Hara et al., 2024), the study explored the usefulness of this framework in enabling SCs and schools to share educational goals and collaboratively plan their support activities. kn-abstract=　2022年に改訂された「生徒指導提要」では，すべての児童生徒の成長を支援する発達支持的生徒指導の重要性が明確に示されている。しかし，その定着には，教員の多忙化や組織的支援体制の不十分さなど，学校現場における多くの課題が指摘されている。さらに，スクールカウンセラー（SC）による支援も十分に展開されているとは言い難い。そこで本稿では，発達支持的生徒指導におけるSCの支援の拡充可能性を検討するため，現状と課題を整理した。また，プランニングシートを活用した実践事例（原他, 2024）の再分析を通して，SCと学校が教育目標を共有しながら協働的に支援を計画する枠組みの有用性を吟味した。 en-copyright= kn-copyright= en-aut-name=HARANoriyuki en-aut-sei=HARA en-aut-mei=Noriyuki kn-aut-name=原範幸 kn-aut-sei=原 kn-aut-mei=範幸 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= en-aut-name=AOKITazuko en-aut-sei=AOKI en-aut-mei=Tazuko kn-aut-name=青木多寿子 kn-aut-sei=青木 kn-aut-mei=多寿子 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山県公立学校スクールカウンセラー affil-num=2 en-affil= kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil= kn-affil=岡山大学学術研究院教育学域 en-keyword=発達支持的生徒指導 (developmentally supportive student guidance) kn-keyword=発達支持的生徒指導 (developmentally supportive student guidance) en-keyword=プランニングシート (Planning Sheet) kn-keyword=プランニングシート (Planning Sheet) en-keyword=スクールカウンセラー (school counselor) kn-keyword=スクールカウンセラー (school counselor) en-keyword=チーム学校 (school as a team) kn-keyword=チーム学校 (school as a team) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=237 end-page=251 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preliminary Consideration on the Introduction of Philosophical Thinking into Special Needs Education: A Methodological Framework Based on the Concepts of Duration, Becoming, and Diffraction kn-title=特別支援教育への哲学的思考導入についての予備的考察 持続・生成変化・回折の考え方に基づく方法的枠組みの試案 en-subtitle= kn-subtitle= en-abstract=This paper presents a theoretical and methodological examination aimed at introducing philosophical thinking into the practice of special needs education in response to contemporary challenges in the field. As its theoretical foundation, the study outlines Bergson’ s theory of memory, Deleuze and Guattari’ s philosophy of becoming, Barad’ s diffractive methodology, and Blom’ s diffractive ethnography. Building upon these theories, it proposes a methodological framework that adopts three interrelated analytical perspectives—“material-discursive practices,” “duration,” and “becoming”—for reading and interpreting educational practices. These perspectives, situated within the paradigm of post-qualitative research, make it possible to understand educational events as relational and processual phenomena rather than fixed outcomes. Future issues include the theoretical integration of the three lenses, clarification of the distinctions between diffractive methodology and diffractive ethnography, and refinement of analytical methods for connecting multiple practice episodes. kn-abstract=　本稿は，現代の特別支援教育の課題から，特別支援教育実践に哲学的思考を導入するための理論的・方法的検討を行うものである。まず，理論基盤として，ベルクソンの「記憶理論」，ドゥルーズ＆ガタリの「生成変化の哲学」，Baradの「回折的方法論」，Blomの「回折的エスノグラフィー」について概説した。そして，理論基盤を基に方法的枠組みとして，「物質－言説的実践」，「持続」，「生成変化」の三つの視点を教育実践を読み解くための相互補完的な分析視点として採用することを提案した。これらの視点は，ポスト質的研究として，出来事を関係的・過程的に捉えることを可能にするものである。今後の課題として，三つのレンズ間の理論的整理，回折的方法論と回折的エスノグラフィーの差異化，および複数の実践エピソードを接続して描くための分析手法の精緻化が挙げられた。 en-copyright= kn-copyright= en-aut-name=HAMADAYo en-aut-sei=HAMADA en-aut-mei=Yo kn-aut-name=濵田曜 kn-aut-sei=濵田 kn-aut-mei=曜 aut-affil-num=1 ORCID= en-aut-name=TAKANOMiyuki en-aut-sei=TAKANO en-aut-mei=Miyuki kn-aut-name=髙野美由紀 kn-aut-sei=髙野 kn-aut-mei=美由紀 aut-affil-num=2 ORCID= en-aut-name=SATOSatoru en-aut-sei=SATO en-aut-mei=Satoru kn-aut-name=佐藤曉 kn-aut-sei=佐藤 kn-aut-mei=曉 aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama Prefectural Okayama Seto Special Needs School kn-affil=岡山県立岡山瀬戸高等支援学校 affil-num=2 en-affil=Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=特別支援教育 (special needs education) kn-keyword=特別支援教育 (special needs education) en-keyword=哲学 (philosophy) kn-keyword=哲学 (philosophy) en-keyword=分析視点 (analytical perspectives) kn-keyword=分析視点 (analytical perspectives) en-keyword=ポストヒューマニズム (posthumanism) kn-keyword=ポストヒューマニズム (posthumanism) en-keyword=質的研究 (qualitative research) kn-keyword=質的研究 (qualitative research) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=221 end-page=235 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Designing an Educational Model and Assessing Outcomes for the Graduate Course “Leadership and SDGs” New Directions in Leadership Education through Theory Learning, Peer Review, and Reflective Practice kn-title=大学院共通科目『リーダーシップとSDGs』の教育モデル構築と成果分析 理論学習・ピアレビュー・省察活動によるリーダーシップ教育の新展開 en-subtitle= kn-subtitle= en-abstract=Okayama University's graduate school has developed and implemented a core course, “Leadership and SDGs,” to foster leadership among graduate students.

By analyzing learning outcomes across different departments, the study demonstrates that reflective, theory-based learning and collaborative critique activities effectively deepen leadership understanding and personal development. This research clarifies the significance of building and continuously improving an educational model that integrates academic theory and practical activities. kn-abstract=　岡山大学大学院では、博士課程人材のリーダーシップ育成に向け、共通科目『リーダーシップとSDGs』を設計・実践している。本科目はSDGsに貢献するリーダー育成に主眼を置き、理論学習・ピアレビュー・省察・グループディスカッション等の手法を組み合わせ、学生同士の学び合い・自己成長の促進を目的としている。本稿では、学部・研究科ごとに学習成果を分析し、理論に基づく省察的学びと協働的な批評活動がリーダーシップ理解や成長に有用であることを明らかにした。本研究は、学術的理論と実践的活動を織り交ぜたモデル構築と、その継続的改善の意義を示している。 en-copyright= kn-copyright= en-aut-name=ISHIDAMamoru en-aut-sei=ISHIDA en-aut-mei=Mamoru kn-aut-name=石田衛 kn-aut-sei=石田 kn-aut-mei=衛 aut-affil-num=1 ORCID= en-aut-name=OTSUNEShinichi en-aut-sei=OTSUNE en-aut-mei=Shinichi kn-aut-name=大常真一 kn-aut-sei=大常 kn-aut-mei=真一 aut-affil-num=2 ORCID= en-aut-name=NAKAZAWATakuya en-aut-sei=NAKAZAWA en-aut-mei=Takuya kn-aut-name=中澤拓也 kn-aut-sei=中澤 kn-aut-mei=拓也 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of General Education and Global Studies, Okayama University kn-affil=岡山大学学術研究院共通教育・グローバル領域 affil-num=2 en-affil=Graduate student, 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=3 en-affil=Graduate student, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil=岡山大学大学院ヘルスシステム統合科学研究科 en-keyword=リーダーシップ教育 (Leadership Education) kn-keyword=リーダーシップ教育 (Leadership Education) en-keyword=学習設計 (Learning Design) kn-keyword=学習設計 (Learning Design) en-keyword=高等教育 (Higher Education) kn-keyword=高等教育 (Higher Education) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=205 end-page=219 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Tier 1 Support of School-Wide Positive Behavior Support (SWPBS) in the High School Division of a Special Needs School for Students with Intellectual Disabilities: Implementation and Effects of a Campaign-Based Approach kn-title=知的障害高等特別支援学校における SWPBS 第１層支援 ―キャンペーン方式の導入とその効果― en-subtitle= kn-subtitle= en-abstract=This study examined the effects of a campaign-based intervention implemented as Tier 1 support within School-Wide Positive Behavior Support (SWPBS). It took place at a public upper secondary school for students with mild intellectual disabilities. A “Thank-You Campaign” was conducted with 24 students in one grade level. The frequency of predefined target behaviors was analyzed using AB design with follow-ups. A social validity questionnaire was also administered to six teachers of the same grade. Results showed that both the frequency of the target behaviors and the percentage of students engaging in those behaviors increased after the campaign. These increases remained above baseline levels for a certain period after the campaign ended. The intervention also demonstrated a moderate degree of social validity. These findings suggest that campaign-based approaches can be a useful form of Tier 1 support in SWPBS for students with mild intellectual disabilities at the upper secondary level. kn-abstract=　本研究は，軽度知的障害のある後期中等教育段階の公立知的障害高等特別支援学校において，SWPBS 第1層支援としてキャンペーン方式の支援を実施し，その効果検証を行った。方法としては，Ｘ学年生徒24名に対して挨拶行動の促進を狙ったキャンペーンを実施し，目標行動の生起数についてABフォローアップデザインを用いて検討した。また，Ｘ学年教員6名に対し，社会的妥当性を評価するアンケートを実施した。その結果，キャンペーンの介入直後に目標行動の生起数および目標行動に従事した生徒の割合の増加が見られ，キャンペーン終了後もベースラインと比較した増加が一定期間確認された。また，一定程度の社会的妥当性も確認できた。 en-copyright= kn-copyright= en-aut-name=TOKIMITSUHideaki en-aut-sei=TOKIMITSU en-aut-mei=Hideaki kn-aut-name=時光秀明 kn-aut-sei=時光 kn-aut-mei=秀明 aut-affil-num=1 ORCID= en-aut-name=MIYAZAKIYoshio en-aut-sei=MIYAZAKI en-aut-mei=Yoshio kn-aut-name=宮﨑善郎 kn-aut-sei=宮﨑 kn-aut-mei=善郎 aut-affil-num=2 ORCID= en-aut-name=KOYAMAMadoka en-aut-sei=KOYAMA en-aut-mei=Madoka kn-aut-name=小山円 kn-aut-sei=小山 kn-aut-mei=円 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Course), Okayama University kn-affil=岡山大学大学院教育学研究科 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 affil-num=3 en-affil=Kurashiki Kotoura Special Needs Seni or High School, Okayama Prefecture kn-affil=岡山県立倉敷琴浦高等支援学校 en-keyword=高等部 (High school division) kn-keyword=高等部 (High school division) en-keyword=軽度知的障害 (Mild intellectual disabilities) kn-keyword=軽度知的障害 (Mild intellectual disabilities) en-keyword=SWPBS（学校規模ポジティブ行動支援）(School-Wide Positive Behavior Support (SWPBS)) kn-keyword=SWPBS（学校規模ポジティブ行動支援）(School-Wide Positive Behavior Support (SWPBS)) en-keyword=第1層支援 (Tier 1 support) kn-keyword=第1層支援 (Tier 1 support) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=191 end-page=203 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Examining a Practical Case of Learning for Community Development –Focusing on the Changes in Awareness of Junior High School Students During Integrated Studies– kn-title=町づくりを考える実践事例の検討 ―総合的な学習の時間を通じた中学生の意識変化に着目して― en-subtitle= kn-subtitle= en-abstract= This study aims to clarify the effects of junior high school students planning community development through collaboration and interaction with others, and the changes in learners that arise from the results of such practice.

The goal of this practice is to foster a change in students' awareness of their town by having them interpret the future and nature of the town from various perspectives in relation to their interactions with others, and consider sustainable ways of living in the town and forming relationships as their own concern. As a result of the practice, students experienced changes in their perspectives and awareness regarding the town and were able to think about the regional issues involved in town development as their own concern. kn-abstract=　本研究は，中学校総合的な学習の時間における町づくりにおいて，他者との協働や相互作用を通じて町づくりを構想し，実践の結果生じた学習者の変化からその効果を明らかにすることを目的としている。また，対話的な学びで重視される他者との相互作用を，中学校の実践に落とし込み，そのあり方についても検討する。本実践のねらいは，多様な視点から町の将来の姿やあり方を人との関わりについて読み解き，持続可能な町のあり方について自分事に引き寄せて考えることで，町に対する意識の変化を促すことにある。実践の結果，学習者の町に対する見方や考え方の意識変化が引き起こされ，町づくりの持つ地域課題について自分事に引き寄せて思考することができた。 en-copyright= kn-copyright= en-aut-name=KAMADAAkemi en-aut-sei=KAMADA en-aut-mei=Akemi kn-aut-name=鎌田明美 kn-aut-sei=鎌田 kn-aut-mei=明美 aut-affil-num=1 ORCID= en-aut-name=KAJIIKazuaki en-aut-sei=KAJII en-aut-mei=Kazuaki kn-aut-name=梶井一暁 kn-aut-sei=梶井 kn-aut-mei=一暁 aut-affil-num=2 ORCID= affil-num=1 en-affil=Anan City Anan First Junior High School kn-affil=阿南市立阿南第一中学校 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=総合的な学習の時間 (the period for integrated studies) kn-keyword=総合的な学習の時間 (the period for integrated studies) en-keyword=中学生 (junior high school student) kn-keyword=中学生 (junior high school student) en-keyword=町づくり (community development) kn-keyword=町づくり (community development) en-keyword=対話的な学び (int eractive lea rning) kn-keyword=対話的な学び (int eractive lea rning) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=181 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Practice and Challenges of Elementary School Moral Education Lessons Utilizing Self-Developed Teaching Materials on the Theme of ‘The Dignity of Life’ kn-title=「生命の尊さ」の自作教材を活用した小学校道徳科授業の実践と課題 en-subtitle= kn-subtitle= en-abstract=This study investigated whether utilizing self-developed teaching materials for the moral content item "The Dignity of Life" could lead elementary school students to deeply reflect on the value of life in relation to their own experiences. The results confirmed that the use of these materials successfully enabled students to empathize with the characters and engage in deep reflection on the moral value of "The Dignity of Life" in a personal context. Conversely, a challenge emerged: due to the strength of the teacher's intent embedded in the original materials, students were occasionally observed tailoring their comments to align with the teacher's expectations. This suggests a potential, albeit unintentional, directionality imposed on student discourse by the instructor. Finally, this paper discusses the necessity of a continuous cycle of practice and reflection to realize truly student-centered moral education lessons. kn-abstract=　本研究では，内容項目「生命の尊さ」に関する自作教材を開発し，授業を実施することによって，子どもが「生命の尊さ」を自分との関わりで深く考えることができるかについて検証した。成果として，自作教材の活用によって子どもが教材の登場人物に共感し，「生命の尊さ」の道徳的価値を自分との関わりで深く考える様子が確認できた。一方，課題として，自作教材へ込めた思いの強さから，子どもが授業者の意図を組みながら発言する姿が見られ，意図せず子どもの発言を方向付けた可能性が示された。最後に，子ども中心の授業の実現に向けて，実践と省察の往還の必要性について議論した。 en-copyright= kn-copyright= en-aut-name=YOSHIKAWAShinji en-aut-sei=YOSHIKAWA en-aut-mei=Shinji kn-aut-name=吉川伸二 kn-aut-sei=吉川 kn-aut-mei=伸二 aut-affil-num=1 ORCID= en-aut-name=IZUMITsuguyuki en-aut-sei=IZUMI en-aut-mei=Tsuguyuki kn-aut-name=伊住継行 kn-aut-sei=伊住 kn-aut-mei=継行 aut-affil-num=2 ORCID= affil-num=1 en-affil=Tsurajimakita Elementary School kn-affil=倉敷市立連島北小学校 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=道徳科 (Moral Education) kn-keyword=道徳科 (Moral Education) en-keyword=自作教材 (Self-developed teaching materials) kn-keyword=自作教材 (Self-developed teaching materials) en-keyword=生命の尊さ (The Dignity of Life) kn-keyword=生命の尊さ (The Dignity of Life) en-keyword=児童 (Children) kn-keyword=児童 (Children) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=167 end-page=180 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on Developing High School Civics Lesson Plan Aimed at Improving Understanding of Constitutionalism: Depending on “We the People” of the Center for Civic Education kn-title=立憲主義に対する認識の改善を目指した高等学校公民科の授業開発研究 ―米国公民教育センター開発『我ら合衆国人民』を手がかりにして― en-subtitle= kn-subtitle= en-abstract=This study aims to develop practicable lessons for high school civics classes that foster an understanding of constitutionalism as the foundation for grasping the Constitution. Traditional Japanese social studies education focused on understanding the Constitution's fundamental principles—popular sovereignty, respect for basic human rights, and pacifism. But, recently, the concept of constitutionalism has gained attention as a means to help students understand what a constitution fundamentally is, and it is now described in textbooks. This study proposes a lesson plan designed to help students appropriately grasp the concept of constitutionalism. In making the lesson plan, we referenced the long-used “We the People” program developed by the Center for Civic Education in U.S. We adapted materials originally created based on the historical context of the United States to fit the Japanese context, utilizing parts of this program. kn-abstract=　本研究は、憲法理解の基本としての立憲主義に対する認識形成を目標とする、高等学校公民科で実践可能な授業の開発を目指したものである。従来の日本の社会科教育においては、憲法理解は日本国憲法の基本原則である国民主権、基本的人権の尊重、平和主義の理解を基本としていたが、近年、そもそも憲法とは何かを理解させるために、立憲主義の概念が注目されるようになり、教科書にも記述されている。本研究は、そのような立憲主義という概念について生徒に適切に理解させることを目指した授業の提案をしようとするものである。授業計画作成にあたっては、米国の公民教育センターが開発し、長年活用されている『我ら合衆国人民（原題 We the People）』を参照し、その一部を活用し、米国の歴史的背景に基づいて作られた教材を、日本の文脈にそって改変した。 en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=MIYAMOTOAyuha en-aut-sei=MIYAMOTO en-aut-mei=Ayuha kn-aut-name=宮本あゆは kn-aut-sei=宮本 kn-aut-mei=あゆは aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil=岡山大学大学院社会文化学研究科社会文化学専攻 en-keyword=授業開発研究 (Lesson Development Research) kn-keyword=授業開発研究 (Lesson Development Research) en-keyword=公民科 (Civic Education) kn-keyword=公民科 (Civic Education) en-keyword=憲法学習 (Constitutional Studies) kn-keyword=憲法学習 (Constitutional Studies) en-keyword=立憲主義 (Constitutionalism) kn-keyword=立憲主義 (Constitutionalism) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=153 end-page=165 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Methods for Implementing Legal Education in Social Studies to Foster Understanding of Criminal Law Through Developing Junior High School Social Studies Lessons Incorporating Mock Trials kn-title=刑法の意義を捉えさせる社会科における法教育実践の方法 ―模擬裁判を取り入れた中学校社会科の授業開発を通して― en-subtitle= kn-subtitle= en-abstract=This study focuses on developing junior high school social studies lessons incorporating mock trials to enhance understanding of criminal law. Legal education in Japanese social studies has traditionally centered on constitutional studies, with very few opportunities to learn about other laws. Given this situation, recent years have seen the development of legal education lessons covering civil law, criminal law, and other areas. Meanwhile, since the introduction of the lay judge system, the development and implementation of social studies lessons incorporating mock trials have become commonplace, and it is no longer unusual for criminal cases to be addressed in social studies classes. This study examines the characteristics and challenges of conventional mock trial-based lessons and aims to develop a junior high school social studies lesson that helps students grasp the significance of criminal law. kn-abstract=　本研究は、刑法の理解に焦点をあて、模擬裁判を取り入れた中学校社会科の授業開発を行なおうとするものである。日本の社会科における法教育は、従来から憲法学習が中心となっており、その他の法律について学ぶ機会は非常に少ない。そのような現状を踏まえて、近年、民法や刑法などを取り上げた法教育の授業開発が行われるようになった。その一方で、裁判員制度導入以降、模擬裁判を取り入れた社会科授業の開発・実践がよく見られるようになっており、刑事事件が社会科授業で取り上げられることも珍しくはなくなった。しかし、そのような授業を担当する教員に、刑法等に関する知識が十分ではなく、模擬裁判の内容と実際の裁判が乖離しているという課題もある。本研究では、従来の模擬裁判を取り入れた授業の特質と課題を検討したうえで、刑法の意義を捉えさせる中学校社会科の授業開発を目指す。 en-copyright= kn-copyright= en-aut-name=MIYAMOTOAyuha en-aut-sei=MIYAMOTO en-aut-mei=Ayuha kn-aut-name=宮本あゆは kn-aut-sei=宮本 kn-aut-mei=あゆは 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 Human ities and So cial Sciences, Okayama University kn-affil=岡山大学大学院社会文化学研究科社会文化学専攻 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=授業開発研究 (Lesson development research) kn-keyword=授業開発研究 (Lesson development research) en-keyword=中学校社会科 (Junior high school social studies) kn-keyword=中学校社会科 (Junior high school social studies) en-keyword=模擬裁判 (Mock trial) kn-keyword=模擬裁判 (Mock trial) en-keyword=刑法 (Criminal law) kn-keyword=刑法 (Criminal law) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=139 end-page=152 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Practical Issues on Differences in Hours of Attendance as Seen in an Interview of Initial Appointment Child Care Teachers kn-title=初任保育教諭の語りに見る園児の在園時間の違いによる実践上の課題 en-subtitle= kn-subtitle= en-abstract=In this paper, we examined practical issues and responses through interviews with novice childcare teachers with a focus on the differences in the length of kindergarteners' attendance time, which characterizes certified childcare centers. As a result, it became obvious that childcare teachers were aware of eight challenges. In addition to the challenge with respect to the “development of childcare ensuring the continuity of play” described in the “Guidelines for Education and Childcare for Certified Childcare Centers,” furthermore, a new challenge regarding “understanding of kindergarteners in consideration of their various attendance time and lifestyles” not described in it was identified. Differences in attendance time due to certification classification inevitably lead to differences in time schedules, locations, and groups during certified childcare centers life. Therefore, in order to clarify what common experiences should be established in certified childcare centers life, what differences in experience should be utilized, and what kind of childcare should be practiced based on the goals set by childcare teachers, a future challenge is to collect and organize good practice examples that have been accumulated so far in certified nurseries and to clarify indicators. kn-abstract=　本論では，幼保連携型認定こども園の特徴である園児の在園時間の違いに焦点を当て，初任保育教諭への面接調査により実践上の課題と対応について検討した。その結果，保育教諭が８つの課題を認識していることが明らかになった。また，『幼保連携型認定こども園教育・保育要領』に記述されている「遊びの連続性を保障する保育の展開」に関する課題に加えて，記述されていない「多様な在園時間や生活形態を考慮した園児理解」に関する新たな課題が見出された。認定区分による在園時間の違いは園生活における時間的スケジュールや場所，集団の違いを余儀なくされる。そのため，保育教諭が設定するねらいに基づいた園生活で何を共通経験とすべき内容として設定し，何を経験差として活かし，どのような保育を実践するか明確にすべく，これまで認定こども園で積み重ねられてきた好実践例を集積・整理し，指標を明示することが今後の課題である。 en-copyright= kn-copyright= en-aut-name=HASUIKazuya en-aut-sei=HASUI en-aut-mei=Kazuya kn-aut-name=蓮井和也 kn-aut-sei=蓮井 kn-aut-mei=和也 aut-affil-num=1 ORCID= en-aut-name=KATAYAMAMika en-aut-sei=KATAYAMA en-aut-mei=Mika kn-aut-name=片山美香 kn-aut-sei=片山 kn-aut-mei=美香 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Health and Welfare， Kawasaki University of Medical Welfare kn-affil=川崎医療福祉大学医療福祉学部 affil-num=2 en-affil=Faculty of Education, Graduate School of Science, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=認定こども園 (Certified Children Centers) kn-keyword=認定こども園 (Certified Children Centers) en-keyword=在園時間の違い (Differences in Hours of Attendance) kn-keyword=在園時間の違い (Differences in Hours of Attendance) en-keyword=実践上の課題 (Issues in Childcare) kn-keyword=実践上の課題 (Issues in Childcare) en-keyword=初任保育教諭 (Initial Appointment Child Care Teachers) kn-keyword=初任保育教諭 (Initial Appointment Child Care Teachers) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=123 end-page=137 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study on the Involvement of Community Wind Bands in the Community Development of Wind Band Activities; Can Community Wind Bands Serve as Key Supporters in Community Development of Club Activities? kn-title=吹奏楽活動の地域展開における市民吹奏楽団の関わりに関する研究 ―市民吹奏楽団は地域展開の担い手になり得るか― en-subtitle= kn-subtitle= en-abstract=In the community development of wind band activities, the shortage of instructors and rehearsal spaces has become an urgent issue.

More proactive bands tended to view providing musical instruction to children and engaging in joint activities positively. On the other hand, concerns about instructional skills, time constraints, and the burden of responsibility were identified as potential obstacles. Furthermore, the findings suggest that utilizing public school facilities could help address the issues of rehearsal space and financial constraints faced by community wind bands. However, disparities among municipalities were also found in the actual implementation of public school facility use systems. kn-abstract=　吹奏楽活動の地域展開（以下、地域展開）において、指導者や活動場所の不足は喫緊の課題である。本研究は、地域展開が進む中で、市民吹奏楽団が地域の子ども達の吹奏楽活動を支える担い手となり得るかを調査・検討した。岡山県内の市民吹奏楽団20 団体への聞き取り調査とテキストマイニング分析の結果、地域展開への意識には差がみられ、積極的な団体では子ども達の演奏指導や合同での活動を肯定的に捉える傾向が確認された。一方で、指導技術や時間的制約、責任負担への不安が障壁となっている可能性が示唆された。また、市民吹奏楽団が抱える活動場所や財政的な課題に対して公立学校施設の活用がその解決に寄与し得る可能性が示唆された。一方で、公立学校の施設開放については、実際の制度運用において自治体間の格差が存在することが明らかとなった。 en-copyright= kn-copyright= en-aut-name=MAKINOKunihiko en-aut-sei=MAKINO en-aut-mei=Kunihiko kn-aut-name=槇野邦彦 kn-aut-sei=槇野 kn-aut-mei=邦彦 aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Teacher Education and Development、Okayama University kn-affil=岡山大学学術研究院教育学域 教育推進機構教師教育開発センター en-keyword=地域展開 (community development of club activities) kn-keyword=地域展開 (community development of club activities) en-keyword=市民吹奏楽団 (community wind band) kn-keyword=市民吹奏楽団 (community wind band) en-keyword=地域クラブ活動 (regional club activities) kn-keyword=地域クラブ活動 (regional club activities) en-keyword=学校施設開放 (community use of school facilities) kn-keyword=学校施設開放 (community use of school facilities) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=107 end-page=121 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Developing Lesson Plan for Global Citizenship Education in Junior High School Music Education through Japan-Korea Music Cultural Exchange: Based on Research Findings from an Internship at APCEIU kn-title=日韓の音楽文化交流を通した中学校音楽科におけるグローバル・シティズンシップ教育の構想 ―APCEIUでのインターンシップにおける調査の成果に基づいて― en-subtitle= kn-subtitle= en-abstract=This paper proposes a Global Citizenship Education program for junior high school music classes.

(2025). In the lesson practice, details of the climate and seasonal cycle around Germany were firstly explained and the German lied “Im Frühling” (In spring) composed by F. Schubert was appreciated, paying attention to how the scenes and emotions expressed by the lyrics “all summer long” in the 3rd verse of this song might differ whether we imagine the climate around Germany or that around Japan. It seems that the present activity provided an opportunity for the students to perceive the climate environments and seasonal feelings quite different from those familiar to them . However, how to explore the appreciation activities that focus also on the musical expression itself of that song is an interesting remaining problem, in order for the students to capture the summer scenery and emotions which Schubert himself imagined. kn-abstract=　「異質な他者」への出会いを促す授業例の更なる蓄積のため，ドイツ付近の「夏」の気候と季節感に注目した教科横断的な授業を大学で実践した。授業では，ドイツ付近の気候と季節サイクルの中での「夏」の特徴を把握すると共に，シューベルトの歌曲《春に》を鑑賞した。《春に》の3 番の「夏の間じゅう，ずっと」という歌詞で歌われている情景や情感が，ドイツ付近と日本付近を想定した場合にどう違い得るか，に関する受講生の記述を分析した。その結果，日本の夏の高温多湿な環境からは原詩の情感そのものが成立し難いと感じた学生もいるなど，本実践は，自分たちの「当たり前」とは異なる気候や季節感にも目を向ける機会になり得たといえる。一方，日本とはかなり違う気候背景の中でシューベルトが思い描いたであろう情景・心情に授業で深く迫るための，音楽表現自体への踏み込み方についても，今後検討する必要性が示唆された。 en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=NAGAOKAIsao en-aut-sei=NAGAOKA en-aut-mei=Isao kn-aut-name=長岡功 kn-aut-sei=長岡 kn-aut-mei=功 aut-affil-num=2 ORCID= en-aut-name=KATOHaruko en-aut-sei=KATO en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 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 affil-num=3 en-affil=Faculty of Education, Gufu Shotoku Gakuen University (Former affiliation) kn-affil=元　岐阜聖徳学園大学教育学部 en-keyword=気候と音楽 kn-keyword=気候と音楽 en-keyword=ドイツ付近の夏の気候と季節感 kn-keyword=ドイツ付近の夏の気候と季節感 en-keyword=気候と文化理解の学際的ESD教師教育 kn-keyword=気候と文化理解の学際的ESD教師教育 en-keyword=異質な他者への理解 kn-keyword=異質な他者への理解 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=61 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on Physical Activity Levels During Soccer Matches Among Junior High School Students Focusing on Position and Physical/Fitness Characteristics kn-title=中学生を対象としたサッカー試合中の身体活動量に関する研究 ～ポジションと身体・体力特性に着目して～ en-subtitle= kn-subtitle= en-abstract=We compared physical and fitness characteristics by soccer position using results from the New Physical Fitness Test administered to 30 junior high school students. Additionally, we compared differences in physical activity levels by position during soccer matches while wearing LC devices. The results showed no significant differences in physical or fitness characteristics between positions. However, significant differences were observed between positions in step count and the proportion of time spent in physical activity by intensity level. This revealed that physical activity levels during soccer matches differ between positions even among junior high school students, clarifying position-specific characteristics in soccer. It also suggested the usefulness of evaluating physical activity levels during matches over time. kn-abstract=　中学生34人を対象とし，身体・体力特性とサッカー試合中の身体活動量について，ポジションに着目して比較・検討した．その結果，身体・体力特性についてはポジション間に有意な差は認められなかった．歩数ではポジション間で有意差が認められ，ライトサイドバックが少なく，センターミッドフィルダーが高かった．強度別身体活動量時間の割合ではポジション間で有意差が認められ，ライトサイドバックが低く，センターミッドフィルダーが高かった．以上のことから，本研究の対象中学生ではポジション間で身体・体力特性には有意差が認められないが，サッカー試合中の身体活動量ではポジション間で差が生じることが示唆された． en-copyright= kn-copyright= en-aut-name=NATSUMEDATakaaki en-aut-sei=NATSUMEDA en-aut-mei=Takaaki kn-aut-name=棗田尊貴 kn-aut-sei=棗田 kn-aut-mei=尊貴 aut-affil-num=1 ORCID= en-aut-name=ADACHIMinoru en-aut-sei=ADACHI en-aut-mei=Minoru kn-aut-name=足立稔 kn-aut-sei=足立 kn-aut-mei=稔 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 affil-num=2 en-affil=Okayama University Graduate School of Education kn-affil=岡山大学学術研究院教育学域 en-keyword=サッカー (Soccer) kn-keyword=サッカー (Soccer) en-keyword=中学生 (Junior High School Students) kn-keyword=中学生 (Junior High School Students) en-keyword=加速度計 (Accelerometer) kn-keyword=加速度計 (Accelerometer) en-keyword=新体力テスト (New Physical Fitness Test) kn-keyword=新体力テスト (New Physical Fitness Test) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=45 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Physical Activity and Physical Fitness in the School Life of Elementary School Children kn-title=小学生の学校生活における身体活動量と体力に関する研究 en-subtitle= kn-subtitle= en-abstract=　The purpose of this study was to objectively measure physical activity levels during different school settings among sixth-grade elementary school children using an accelerometer, and to examine their relationship with physical fitness. Participants were 85 children (41 boys, 44 girls). Step counts and time spent in different activity intensities were evaluated during recess, physical education (PE) classes, and the whole school day. Results showed that children with higher fitness levels tended to have greater step counts and more moderate-to-vigorous physical activity (MVPA) during recess. Significant differences were found in morning recess for boys and in lunch recess and PE classes for girls. The proportion of MVPA was 11.3% during recess and 15.7% during PE classes, which was lower than that reported in other countries and did not meet international recommendations. This study provides fundamental data on physical activity in elementary school settings and suggests the importance of enhancing opportunities for physical activity, parti cularly during recess and PE classes. kn-abstract=　本研究の目的は，小学校6年生の学校生活における活動場面別の身体活動量を加速度計を用いて客観的に測定し，その体力との関係を検討することである．対象は小学校児童85名(男子41名，女子44名)とし，休み時間，体育授業，学校生活全体における歩数と強度別活動時間を評価した．その結果，男女ともに体力上位群は休み時間において歩数とMVPAが多い傾向が示され，特に男子は中休み，女子は昼休みおよび体育授業で有意差が認められた．各活動場面のMVPA が占める割合は休み時間11.3％，体育授業15.7％であり，諸外国と比較して少なく，国際的推奨値にも届かなかった．本研究は，小学校における身体活動量の基礎データを提示するとともに，学校生活，特に休み時間や体育授業における身体活動機会の充実が必要であることを示唆した． en-copyright= kn-copyright= en-aut-name=YASUNOBEJin en-aut-sei=YASUNOBE en-aut-mei=Jin kn-aut-name=安延仁 kn-aut-sei=安延 kn-aut-mei=仁 aut-affil-num=1 ORCID= en-aut-name=SASAYAMAKensaku en-aut-sei=SASAYAMA en-aut-mei=Kensaku kn-aut-name=笹山健作 kn-aut-sei=笹山 kn-aut-mei=健作 aut-affil-num=2 ORCID= en-aut-name=ADACHIMinoru en-aut-sei=ADACHI en-aut-mei=Minoru kn-aut-name=足立稔 kn-aut-sei=足立 kn-aut-mei=稔 aut-affil-num=3 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 affil-num=2 en-affil=Faculty of Education, Mie University kn-affil=三重大学教育学部 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=加速度計 (accelerometer) kn-keyword=加速度計 (accelerometer) en-keyword=身体活動量 (physical activity) kn-keyword=身体活動量 (physical activity) en-keyword=体力 (physical fitness) kn-keyword=体力 (physical fitness) en-keyword=小学校児童 (elementary school children) kn-keyword=小学校児童 (elementary school children) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=31 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of Factors Contributing to Confusion Regarding Left-Right Understanding of Convex Lens Images —Proposals for Inquiry-Based Learning Based on Textbook Analysis and Teacher Questionnaire— kn-title=凸レンズの像の左右理解に関する混乱の要因分析 教科書分析と教員アンケートによる探究的な学びへの提案 en-subtitle= kn-subtitle= en-abstract=This study focused on the confusion students experience regarding the orientation of images during the learning of convex lens in junior high school. It examined the causes of this confusion, identifying insufficient awareness of experimental conditions such as the light source, screen, and observation location. To investigate, the study analyzed changes in the Course of Study for Lower Secondary Schools and textbooks and conducted a questionnaire survey of science teachers. The results revealed that while textbook descriptions have shifted toward specifying the observation location, teaching methods among teachers vary, causing confusion of students. To address these issues, a 3D-printed teaching material was developed that naturally fixes the observation viewpoint. Its effectiveness was examined through teacher training. This material was found to be effective in promoting students' intuitive understanding and bringing inquiry-based learning. kn-abstract=　本研究は、中学校理科の凸レンズ学習で生徒が像の向きに抱く混乱に着目した。その要因を、光源・スクリーン・観察場所といった実験条件が十分に意識されてこなかった点にあると考察し、学習指導要領と教科書の変遷分析、および現職教員へのアンケート調査を実施した。その結果、教科書の記述は観察場所を指定する方向へ変化しているものの、現場教員の指導法にはばらつきがあり、生徒の混乱を招く一因となっていることを明らかにした。これらの課題解決のため、観察視点を自然に固定できる3D プリンタ製教材を開発し、教員研修でその有効性を検討した。本教材は生徒の直感的理解を促し、探究的な学びを引き出す上で有効であることが示唆された。 en-copyright= kn-copyright= en-aut-name=TANIMOTOKunihiko en-aut-sei=TANIMOTO en-aut-mei=Kunihiko kn-aut-name=谷本薫彦 kn-aut-sei=谷本 kn-aut-mei=薫彦 aut-affil-num=1 ORCID= en-aut-name=INADAYoshihiko en-aut-sei=INADA en-aut-mei=Yoshihiko kn-aut-name=稲田佳彦 kn-aut-sei=稲田 kn-aut-mei=佳彦 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 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=凸レンズ (Convex lens) kn-keyword=凸レンズ (Convex lens) en-keyword=上下左右逆 (the orientation of images) kn-keyword=上下左右逆 (the orientation of images) en-keyword=教科書 (Textbooks) kn-keyword=教科書 (Textbooks) en-keyword=学習指導要領 (Course of Study) kn-keyword=学習指導要領 (Course of Study) en-keyword=３D プリンタ (3D printer) kn-keyword=３D プリンタ (3D printer) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=15 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Critical Reading Instruction of Expository Text that Promotes Reflecting: Practice for First-year Student at High School kn-title=説明的文章の指導における「内省」を促す批判的読み ―高等学校１年生を対象として― en-subtitle= kn-subtitle= en-abstract=　Critical reading is an essential skill at present time and is included in government guidelines for teaching. Although recent research on teaching critical reading has been conducted, there have been criticisms that lack of consideration of content value and understanding context within society. There are also calls for critical reading that focuses on the perspective of “reflect” . Therefore, this paper developed a lesson that encourages students not only critically read the text, but also critically consider (reflect on) their own ideas. As a measure to achieve this, incorporated activities such as comparing two teaching materials that contained multiple social perceptions, exchanging opinions from opposing perspectives, writing an evaluation of the materials, and having the students themselves evaluate their own writing (their own reading). Analysis of the students’ writings shows that, while some students didn’ t reach conscious reflection, about 60% of students’ writings showed changes. And then it suggests that the methods used were effective. kn-abstract=　批判的読みは，現代では欠かせない能力であり，学習指導要領にも明記されている。近年，批判的読みの指導に関する研究がなされているものの，内容的な価値の検討や社会的な文脈のなかで捉えることが希薄だとする指摘や，「反省性」という観点に着目した批判的読みを求める声もある。そこで，本稿では，文章そのものを批判的に読むだけでなく，自身の持っている考えをも批判的に捉える（内省する）ことを促す授業を開発した。その手立てとして，複数の社会認識が存在する二つの教材の読み比べたうえで，対立する立場からの意見交換を行うことや，教材に対する評価の記述，その記述（自己の読み）を学習者自身が評価するといった活動を取り入れた。学習者の記述の分析からは，意識的な内省に至らなかった学習者も見受けられたものの，約６割の学習者の記述には変容が見られ，用いた手立ては効果があったと推測できることを指摘した。 en-copyright= kn-copyright= en-aut-name=SAISHOYumi en-aut-sei=SAISHO en-aut-mei=Yumi kn-aut-name=最相有未 kn-aut-sei=最相 kn-aut-mei=有未 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科 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=反省性 (reflectiveness) kn-keyword=反省性 (reflectiveness) en-keyword=情意的性向 (affective disposition) kn-keyword=情意的性向 (affective disposition) en-keyword=複数テクスト (multiple texts) kn-keyword=複数テクスト (multiple texts) en-keyword=「現代の国語」 (“Contemporary Japanese Language”) kn-keyword=「現代の国語」 (“Contemporary Japanese Language”) en-keyword=生物多様性 (biodiversity) kn-keyword=生物多様性 (biodiversity) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preschool Teachers’ Strategies and Practical Challenges in Supporting the School Enrollment of Foreign Children kn-title=外国人幼児の就学支援における保育士の工夫と実践的課題 en-subtitle= kn-subtitle= en-abstract=This study aimed to clarify the specific practices and challenges faced by preschool teachers in supporting foreign children at the time of school enrollment. Semi-structured interviews were conducted with two preschool teachers who had experience in supporting foreign children, and qualitative analysis using SCAT was applied to organize the support provided to both children and their parents. The results revealed that, in terms of language support, teachers utilized visual aids and simplified Japanese, while in cultural support they sought to balance family culture with the culture of the preschool. Regarding developmental support, the importance of fostering non-cognitive skills and collaborating with medical institutions was highlighted. In parent support, participatory involvement and careful explanations were practiced; however, challenges remained in providing institutional information and establishing collaboration with local governments. Based on these findings, it is necessary to establish a regional collaborative system that can provide institutional support for families with multicultural backgrounds, standardize the provision of information, and build practical mechanisms to connect with Japanese language education resources, so that support does not rely solely on the individual efforts of preschool teachers. kn-abstract=　本研究は，外国人幼児が就学期に直面する困難に対応するため，保育士が行っている具体的な保育実践における支援の工夫と課題を明らかにすることを目的とした。外国人幼児の支援経験を有する保育士2 名に半構造化インタビューを行い，SCAT を用いた質的分析により，幼児および保護者への支援内容を整理した。その結果，言語面では視覚的支援ややさしい日本語を活用し，文化面では家庭文化と日本の園文化の調整が行われていた。発達支援においては，非認知的スキルの育成や医療機関との連携の必要性が指摘された。保護者支援では，参加型の関わりや丁寧な説明が実践されていたが，制度情報の提供や行政との連携には課題が残された。これらの結果を踏まえ，今後は保育士の個別的努力に依存しないためにも，多文化背景をもつ家庭への支援を制度的に支える地域連携体制の整備や，情報提供の標準化，日本語教育資源との接続を図る実践的仕組みの構築が求められる。 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=YANAGISAWAKazuki en-aut-sei=YANAGISAWA en-aut-mei=Kazuki kn-aut-name=柳澤佳月 kn-aut-sei=柳澤 kn-aut-mei=佳月 aut-affil-num=2 ORCID= en-aut-name=REN Xinyu en-aut-sei=REN en-aut-mei= Xinyu kn-aut-name=任芯于 kn-aut-sei=任 kn-aut-mei=芯于 aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=The Joint Graduate School (Ph.D. Program) in Science of School Education, Hyogo University of Teacher, 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=岡山大学大学院教育学研究科 affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=外国人幼児 (foreign preschool children) kn-keyword=外国人幼児 (foreign preschool children) en-keyword=就学 (school enrollment) kn-keyword=就学 (school enrollment) en-keyword=保育士 (preschool teachers) kn-keyword=保育士 (preschool teachers) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学教育推進機構 教師教育開発センター紀要 第16号 全文（一括ダウンロード用） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= 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=2026 dt-pub=20260325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathological and transcriptomic profiles of 101 patients with diffuse large B-cell lymphoma/high-grade B-cell lymphoma with double-hit MYC and BCL2 or BCL6 and triple hit en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: Diffuse large B-cell lymphoma/high-grade B-cell lymphoma (DLBCL/HGBCL) with MYC and BCL2 rearrangements (double-hit lymphoma with BCL2, DHL-BCL2) is a mature aggressive B-cell lymphoma that also includes concurrent triple hit with BCL6 translocation (TH). DHL with MYC and BCL6 (DH-BCL6) can also occur. The differences among these three DLBCL/HGBCL subtypes have not yet been definitively determined.
Methods and Results: This study characterized the clinicopathological features and transcriptomic profiles of a series of 101 cases of DLBCL/HGBCL that were subclassified according to MYC, BCL2 and BCL6 FISH data, including cell-of-origin (COO)-like, molecular high-grade (MHG)-like and double-hit/dark-zone (DHIT/DZsig)-like signatures. DLBCL/HGBCL-DH-BCL2 was characterized by higher HGBCL morphology, CD10 positivity, GCB Hans's, GCB COO and MHG molecular subtype. DLBCL/HGBCL-TH had higher LDH levels and worse overall survival. DLBCL/HGBCL-DH-BCL6 had higher MUM1 expression, non-GCB Hans', ABC/Unclassified COO, non-MHG and low DHIT/DZ signatures. Transcriptomic analysis showed that DLBCL/HGBCL-DH-BCL2 and DLBCL/HGBCL-TH were close but separated from DLBCL/HGBCL-DH-BCL6. Gene set enrichment analysis (GSEA) revealed different levels of enrichment between the subtypes.
Conclusions: DLBCL/HGBCL-DH-BCL6 differs from the DLBCL/HGBCL-DH-BCL2, and the DLBCL/HGBCL-TH is associated with the worst survival. Analysis of all three genes of MYC, BCL2 and BCL6 is recommended in the context of DLBCL/HGBCL diagnosis. en-copyright= kn-copyright= en-aut-name=MiyaokaMasashi en-aut-sei=Miyaoka en-aut-mei=Masashi

Fabrication and Characterization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular mechanotransduction signals play a crucial role in physiological and pathological conditions, including skeletal disorders. Although various systems exist to mechanically stimulate cultured cells, most are constrained by incubator incompatibility, limited physiological relevance, nonuniform stimulation, or complexity. The objective of this article is to develop and validate a compact, incubator-compatible tool capable of delivering localized and physiologically relevant mechanical stimulation to small cell populations. Here, we introduce a polypyrrole-based wire-shaped microactuator designed to induce localized mechanical stress to adjacent cells. These wire-shaped microactuators are biocompatible, easy-to-use, and compact for use within standard in vitro cell culture systems. Using a noncontact optical method, we characterize the actuation of polypyrrole-coated wires in an aqueous NaDBS electrolyte, showing radial expansion of 1.5–8 µm depending on the deposited polypyrrole film thickness, comparable to cellular dimensions. Next, the actuation is confirmed to be robust and stable to use in cell culture media at physiological temperature. To evaluate biological relevance, osteoblastic KUSA-A1 cells are mechanically stimulated inside the incubator and transcriptomic changes are assessed. Mechanical stimulation resulted in upregulation of genes previously associated with mechanotransduction, including Fos and Fosb. Additionally, several uncharacterized long noncoding RNAs are differentially expressed, suggesting potential novel players in the mechanotransduction pathway. en-copyright= kn-copyright= en-aut-name=Ortega‐SantosAmaia B. en-aut-sei=Ortega‐Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MartínezJose G. en-aut-sei=Martínez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=JagerEdwin W.

In our previous work, we constructed a non-interactive proactive secret scheme by integrating threshold homomorphic encryption (ThHE) while reducing the communication complexity to 𝑂(𝑛). Not only is refreshing shares important but revoking the shares of users who have left the system is also essential in practical dynamic membership scenarios. However, the previous work was insufficient for supporting explicit user revocation. This study strengthens the description of roles for authorized users and proposes a scheme to achieve non-interactive share refresh and dynamic user management. In each epoch, authorized users are classified into three roles: retain, newly join, and rejoin, and they receive a broadcast of the compact ciphertext encoding both the refresh information and the revocation instructions from the trusted center (dealer). Authorized users independently derive new shares through homomorphic computations, whereas revoked users are unable to generate new shares. Hash functions are used to bind revocation parameters to the cryptographic hashes of valid users in order to guarantee integrity during revocation, allowing for effective verification without compromising non-interactivity. Our new scheme not only extends the revocation structure but also preserves the 𝑂(𝑛) communication complexity. en-copyright= kn-copyright= en-aut-name=HeYixuan en-aut-sei=He en-aut-mei=Yixuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul 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=Interdisciplinary Education and Research Field, Okayama University kn-affil= en-keyword=proactive secret sharing kn-keyword=proactive secret sharing en-keyword=user revocation kn-keyword=user revocation en-keyword=threshold homomorphic encryption kn-keyword=threshold homomorphic encryption en-keyword=non-interactive kn-keyword=non-interactive END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=21 article-no= start-page=6651 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Integrated Authentication Server Design for Efficient Kerberos–Blockchain VANET Authentication en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vehicular Ad Hoc Network (VANET) is a fundamental component of the intelligent transportation systems (ITS), providing critical road information to users. However, the volatility of VANETs creates significant vulnerabilities from malicious actors. Thus, verifying joining entities is crucial to maintaining the VANET’s communication security. Authentication delays must stay below 100 ms to meet VANET requirements, posing a major challenge for security. Our previous research introduced a Kerberos–Blockchain (KBC) authentication system that contains two main components separately: Authentication Server (AS) and Ticket Granting Server (TGS). However, this KBC architecture required an additional server to accommodate increasing vehicle volumes in urban environments, leading to higher infrastructure costs. This paper presents an integrated authentication server that merges AS and TGS into a Combined Server (CBS) while retaining blockchain security. We evaluate it using OMNeT++ with SUMO for traffic simulation and Ganache for blockchain implementation. Results show that CBS removes the need for an extra server while keeping authentication delays under 100 ms. It also improves throughput by 104% and reduces signaling overhead by 45% compared to KBC. By optimizing authentication without compromising security, the integrated server greatly enhances the cost-effectiveness and efficiency of VANET systems. en-copyright= kn-copyright= en-aut-name=RahayuMaya en-aut-sei=Rahayu en-aut-mei=Maya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HossainMd.

A common method used to protect against these kinds of threats is the use of intrusion detection systems (IDS). However, the agricultural environment is often changing and has limited resources, which makes cybersecurity challenging. Several available IDS tools are not designed to work properly in places with few resources, intermittent access, and unpredictable network conditions. This paper investigates the performance of Zeek, an open-source IDS, in identifying potential threats in agricultural IoT networks. We performed both offline and real-time experiments: offline analysis used pcap files from the Stratosphere Laboratory dataset, and real-time evaluation involved simulated live attack scenarios, focusing on unauthorized access attempts and distributed denial-of-service (DDoS) attacks. Zeek's performance was assessed based on CPU and memory utilization, as well as quality of service (QoS) metrics. From the experimental results, we found that Zeek was quite effective in protecting agricultural IoT networks against typical threats. Memory usage remained stable around 5% during offline analysis and under 20% during active attacks. However, CPU usage was more volatile, peaking at 120% during DDoS events. In terms of QoS, the system maintained a good throughput (1,375 kbits/s) with minimal packet loss (0.000186%). Among the attack types that we tested, brute force attacks, which represent attempts at unauthorized access, had the strongest effect on network performance, increasing delay to 2.159 ms and jitter to 0.793 ms. It seems clear that a heavier traffic load during such attacks can interfere with QoS. On the basis of our observation, we recommend practical deployment strategies for agricultural IoT systems that take these limitations into consideration, aiming to keep networks both secure and efficient under pressure. en-copyright= kn-copyright= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MusthafaMuhammad Bisri en-aut-sei=Musthafa en-aut-mei=Muhammad Bisri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShamimS.

To test this model, the study focuses on scenarios where the turbulence under acceleration is steady and isotropic, since the model suggests that this type of acceleration has no effect on the turbulent kinetic energy. To examine this suggestion, the turbulence within a periodic box was analyzed using large-eddy simulation (LES) based on the conventional Smagorinsky model framework. The numerical analysis is based on a method that conserves velocity fluctuation intensities. The results show that while high rate of acceleration deviates turbulent kinetic energy, low rate acceleration has hardly any effect on turbulent kinetic energy, enstrophy, pressure fluctuation, relative pressure fluctuation intensity, and higher-order statistics of a velocity fluctuation. These results validate the accuracy of the model proposed in the previous studies. These results were obtained by focusing on differences in Reynolds numbers and the spatial scale of the forcing. en-copyright= kn-copyright= en-aut-name=ONOAkira en-aut-sei=ONO en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento 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=Turbulent flows kn-keyword=Turbulent flows en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Homogeneous turbulence kn-keyword=Homogeneous turbulence en-keyword=K-epsilon model kn-keyword=K-epsilon model en-keyword=Wind tunnel blockage kn-keyword=Wind tunnel blockage END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=33 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Large-scale rainfall characteristics at the heavy rainfall event around the western Japan during 5–7 July 2018 kn-title=2018年7月5日〜7日の西日本豪雨における広域降水特性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Large-scale rainfall characteristics at the heavy rainfall event around the western Japan for 5–7 July 2018 were analyzed with use of the 10-mimute precipitation data at the surface meteorological observation stations of the Japan Meteorological Agency, and so on. In this case, the area with 3 days total precipitation of near or more than 300 mm was distributed widely from northern Kyushu to Shiga and Fukui Prefectures. As in the many heavy rainfall events around Kyushu District in the mature stage of the Baiu season, contribution of the intense rainfall with more than 4 mm/10-minute (24 mm/h) attained about one third of the areal mean total precipitation. However, it is noted that the "not so intense rain" with less than 2 mm/10-minute (12 mm/h) also contributed to about one third of the huge total precipitation in the wide area. In short, this case could be characterized by the mixture of the western Japan type heavy rainfall event and the eastern Japan type one. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=MATSUMOTOKengo en-aut-sei=MATSUMOTO en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=2 ORCID= en-aut-name=OTANIKazuo en-aut-sei=OTANI en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域（理科） affil-num=2 en-affil=Okayama Gakugeikan High School kn-affil=岡山学芸館高等学校 affil-num=3 en-affil=TV Setouchi Broadcasting Co., LTD. kn-affil=テレビせとうち(株) en-keyword=western Japan heavy rainfall in July 2018 kn-keyword=western Japan heavy rainfall in July 2018 en-keyword=10-minute precipitation data kn-keyword=10-minute precipitation data en-keyword=east-west difference of the Baiu precipitation kn-keyword=east-west difference of the Baiu precipitation END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=21 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A trial of lesson practice at the university on the variety of heavy rainfall characteristics based on the 10-minute precipitation data toward promoting the meteorological disaster prevention literacy kn-title=10分間降水量から大雨の特徴の多様性を捉える大学での授業の試み（防災気象リテラシー育成へ向けて） en-subtitle= kn-subtitle= en-abstract= kn-abstract=　In the disaster prevention education on the heavy rainfall around Japan, it is also important to promote the meteorological literacy on the seasonal and regional differences of their rainfall characteristics such as the convective rain or stratiform rain, together with their total amount of precipitation and their occurrence frequency. As the first step toward the above purpose, the present study made a lesson practice for the university students by utilizing the 10-minute precipitation data for the four heavy rainfall events, in which the types of the heavy rainfall (although all the cases examined in the lesson are relating to the deep convective clouds) are rather different from each other, such as the differences of the rainfall intensity at the peak time, short-period variation of the rainfall intensity and the persistency of the rainfall including the "not so intense rainfall". The reports by the students seem to perceive the different features among these events briefly, but the students' attention to how long the intense rainfall with short-period variation or "not so intense rainfall" lasted was not so sufficient. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域（理科） en-keyword=disaster prevention education kn-keyword=disaster prevention education en-keyword=variety of the heavy rainfall characteristics kn-keyword=variety of the heavy rainfall characteristics en-keyword=meteorological disaster prevention literacy kn-keyword=meteorological disaster prevention literacy en-keyword=use of the 10-minute precipitation data kn-keyword=use of the 10-minute precipitation data 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=2026 dt-pub=20260325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山市向場・黒住丘陵の遺跡測量調査概要報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=光本順 kn-aut-sei=光本 kn-aut-mei=順 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=川月青 kn-aut-sei=川月 kn-aut-mei=青 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=坂野碧斗 kn-aut-sei=坂野 kn-aut-mei=碧斗 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue= article-no= start-page=101798 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alcohol consumption, smoking, and the implications of their cessations for field carcinogenesis in the esophagus: a 10-year prospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Alcohol and tobacco are established carcinogens, which promote field carcinogenesis for esophageal squamous cell carcinoma (ESCC). This study aimed to evaluate the long-term effects of alcohol and tobacco cessations, and background mucosal status, on risk for metachronous ESCC (mESCC) after endoscopic resection (ER).
Methods This was a multicentre prospective cohort study of patients with intramucosal ESCC treated by ER. All participants received structured education on cessation, and underwent regular endoscopic surveillance. Patients were stratified by Lugol-voiding lesion (LVL) grade (A: none, B: 1–9, C: ≥10). The impacts of alcohol and smoking cessation on field carcinogenesis were assessed.
Findings Among 331 enrolled patients, the median follow-up was 120 months (range: 1.3–176.9). The cumulative incidences of mESCC were 10.4%, 27.2%, and 61.8% in grades A, B, and C, respectively. An increment of 1 unit (22 g ethanol) of alcohol consumption and higher LVL grade independently increased the risk for mESCC. Alcohol or smoking cessation reduced this risk (hazard ratio [HR] 0.52, 95% confidence interval [CI]: 0.31–0.88; HR 0.44, 95% CI: 0.25–0.78, respectively), and combined cessation had the greatest impact (HR 0.21, 95% CI: 0.07–0.65). Complete cessation, rather than partial reduction, was necessary to achieve meaningful risk reduction.
Interpretation Alcohol and tobacco exposure, and a large number of LVL, are major determinants of mESCC. Complete cessation markedly reduces risk, underscoring the importance of behavioural interventions for secondary prevention of field carcinogenesis after ER. en-copyright= kn-copyright=

Educational Intervention Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In the field of team-based care, pharmacists are vital for optimizing medication therapy. However, many medical professionals lack the opportunity to learn how to propose prescription changes with precision.
Objective: This study aimed to address this knowledge gap by developing and assessing a new educational program for pharmacy students focused on prescription support and interprofessional collaboration.
Methods: We recruited 191 fifth-year pharmaceutical students during the 2022‐2024 academic years. The program featured a 7-day intensive curriculum that included learning how to assist with prescriptions, analyzing clinical data, and engaging in role-playing exercises. A web-based questionnaire and a paper test were used to evaluate students’ awareness and knowledge both before and after the program. Statistical analyses were performed to verify the significance of changes; we utilized the Wilcoxon signed-rank test for the ordinal data derived from the specific behavioral objectives and 2-tailed paired t tests for the interval data from the knowledge tests. The magnitude of change was quantified using r for Wilcoxon tests and Cohen dz for 2-tailed t tests, with 95% CI calculated to ensure the stability and reliability of the observed results.
Results: Analysis of the primary outcome specific behavioral objectives revealed statistically significant effects across all items (Wilcoxon signed-rank test; P<.001). Effect sizes (r=0.505‐0.835) ranged from moderate to large, with particularly large effects observed in identifying contents issue (r=0.835, 95% CI 0.126-0.330; P<.001). Knowledge test scores showed significant improvement in the following 3 subjects: pharmacology (r=−0.504, 95% CI –0.215 to 0.127; P<.001), organic chemistry (r=0.254, 95% CI –0.148 to –0.193; P=.004), and communication (r=0.221, 95% CI –0.151 to –0.190; P=.01). No significant changes were observed in pathology or pharmacokinetics.
Conclusions: This program provides strong evidence that practical, hands-on learning with hospital pharmacists helps improve pharmacy students’ professional skills and optimize pharmaceutical therapies in interprofessional care.

Among these, innate immunity plays a critical role in fish as the first line of defense, coordinating rapid responses to pathogen infections. However, the lack of fish-specific immunological methodologies has limited progress in elucidating fish immune mechanisms. To better understand how the innate immune response develops and resolves in fish, detailed observation and integrative analysis of leukocytes at multiple time points is necessary. In the present study, an intra-fin injection method for observing local immune responses in Japanese medaka (Oryzias latipes) was tested and optimized to analyze the progression of zymosan-induced innate immune responses. Zymosan-injected medaka showed a rapid immune response characterized by leukocyte recruitment and phagocytosis. Using TG(FmpxP:mCherry) transgenic medaka with mCherry fluorescence driven by myeloperoxidase (mpx) promoter, granulocyte chemotaxis towards the site of zymosan entry was successfully visualized. The rapid increase in tumor necrosis factor α (tnfa), interleukin-1β (il1b), interleukin-6 (il6), and CXC motif chemokine ligand 8 (cxcl8) expressions in zymosan-injected anal fins provided a molecular basis for the visualized tissue-specific cellular response. Our study underscores the dynamic orchestration of immune components during the innate immune response in Japanese medaka and highlights their potential as a promising model for immunological research. en-copyright= kn-copyright= en-aut-name=RyuTsukasa en-aut-sei=Ryu en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshinoMizuki en-aut-sei=Yoshino en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TseWilliam Ka Fai en-aut-sei=Tse en-aut-mei=William Ka Fai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IguchiTaisen en-aut-sei=Iguchi en-aut-mei=Taisen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumarAnu en-aut-sei=Kumar en-aut-mei=Anu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SomamotoTomonori en-aut-sei=Somamoto en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakaoMiki en-aut-sei=Nakao en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OginoYukiko en-aut-sei=Ogino en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=2 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biology, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Developmental Disorders and Toxicology, Kyushu University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Nanobioscience, Yokohama City University kn-affil= affil-num=6 en-affil=Commonwealth Scientific and Industrial Research Organisation, CSIRO Environment kn-affil= affil-num=7 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=8 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=9 en-affil=Center for Promotion of International Education and Research, Faculty of Agriculture, Kyushu University kn-affil= en-keyword=Chemotaxis kn-keyword=Chemotaxis en-keyword=Local immunity kn-keyword=Local immunity en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Innate immunity kn-keyword=Innate immunity en-keyword=Phagocytosis kn-keyword=Phagocytosis en-keyword=Zymosan kn-keyword=Zymosan END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=888 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TRPV2 in muscle satellite cells is crucial for skeletal muscle remodelling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal muscle remodelling relies on muscle stem cells (MuSCs) for regeneration after injury and hypertrophy in response to mechanical loading. However, the mechanisms that trigger MuSC activation and proliferation remain unclear. Transient receptor potential vanilloid 2 (TRPV2) ion channels respond to insulin-like growth factor-1 and mechanical stimuli to regulate the biological characteristics of various cells. Using a temporally inducible MuSC-specific conditional knockout (cKO) mouse, we show that TRPV2 regulates MuSC function and is essential for muscle remodelling. In cultured myofibre, MuSCs express TRPV2 and exhibit Ca2+ responses to the TRPV2 agonists 2-aminoethoxydiphenyl borate and probenecid, which are abolished upon TRPV2 deletion. TRPV2-deficient MuSCs exhibit reduced paired box 7 (Pax7) expression and impaired proliferation, suggesting TRPV2 is a factor that regulates the early stage of MuSC function. Myotube formation in MuSCs was enhanced by overexpression of TRPV2 and suppressed by TRPV2 deficiency, suggesting that TRPV2 is a factor that promotes myogenesis. Muscle-administered cardiotoxin promoted muscle regeneration and resulted in the appearance of numerous Pax7-positive MuSCs between myofibres. MuSC-specific TRPV2 cKO mice exhibit substantially impaired muscle regeneration after cardiotoxin-induced injury, drastically reducing Pax7-positive MuSCs between myofibres. In floxed mice, mechanical loading via synergist ablation induces hypertrophy and greatly increases the number of myonuclei per myofibre. In contrast, MuSC-specific TRPV2 cKO mice show no changes in myofibre thickness or nuclear number, either at baseline or after mechanical loading. Mechanical loading of floxed mice increased TRPV2+/Pax7+ double-positive MuSCs, but MuSC-specific TRPV2 cKO mice showed no change. Additionally, MuSCs exhibit Ca2+ responses to hypo-osmotic stimuli, which are suppressed by TRPV2 inhibitors and TRPV2 deletion, suggesting that MuSCs exhibit TRPV2-dependent mechanical responses. These results establish TRPV2 as a critical regulator of MuSC-mediated muscle remodelling, an important finding that may lead to therapeutic strategies for muscle repair and adaptation. en-copyright= kn-copyright= en-aut-name=ChenYanzhu en-aut-sei=Chen en-aut-mei=Yanzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatanosakaKimiaki en-aut-sei=Katanosaka en-aut-mei=Kimiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibuyaMakoto en-aut-sei=Shibuya en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DongYubing en-aut-sei=Dong en-aut-mei=Yubing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhangLidan en-aut-sei=Zhang en-aut-mei=Lidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanagawaMotoi en-aut-sei=Kanagawa en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukadaSo-ichiro en-aut-sei=Fukada en-aut-mei=So-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=KatanosakaYuki en-aut-sei=Katanosaka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biomedical Sciences, College of Life and Health Sciences, Chubu University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Stem Cell Regeneration and Adaptation, Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= affil-num=6 en-affil=Department of Cell Biology and Molecular Medicine, Ehime University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Laboratory of Stem Cell Regeneration and Adaptation, Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= affil-num=8 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= 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=2026 dt-pub=20260225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high-throughput screening, together with an Escherichia coli library containing plasmid clones of all genes from strain W3110, to identify genes whose overexpression enhances virulence. We found that overexpression of the uncharacterized protein YaiX promoted bacterial proliferation in silkworms and increased host lethality. Compared with the empty-vector control, the YaiX-overexpressing strain exhibited resistance to multiple antimicrobial agents with diverse mechanisms of action, including β-lactams, tetracyclines, fluoroquinolones, aminoglycosides, cationic surfactants, and hydrogen peroxide. Sequence analysis revealed that amino acids 18–52 of YaiX contain a transferase hexapeptide domain predicted to form a left-handed parallel β-helix. Overexpression of YaiX mutants lacking regions outside this domain conferred ampicillin resistance, whereas deletion of the hexapeptide domain abolished this phenotype. RNA sequencing and GO enrichment analyses further indicated that YaiX overexpression altered the expression of genes encoding RNA-binding proteins and porins. These findings suggest that YaiX overexpression, through its hexapeptide domain, modulates gene expression and contributes to both multidrug resistance and enhanced virulence in E. coli. en-copyright=

kn-abstract=　本研究は，清田哲男の理論枠組を基盤として，教員が日常生活で出会う市井の他者との対話を通じて創造性や授業観を変容させるプロセスを明確化したものである。市井プロジェクトの質的分析により，教員は他者の生き方や姿勢から新たな価値を受け取り（市井からの享受過程），その経験を契機に教育観を再編し（教育観変容過程），さらに授業構想に具体的変化を生じさせること（授業内容関与過程）が確認された。とりわけ，制度的研修では得にくい偶発的対話や生活知の受容が，教員の創造性を喚起し，日常に根ざした学びとして機能する点が成果である。本研究は，教員自身が学ぶ創造性という新たな研究領域の基盤を形成し，美術教育における創造性育成の新たな可能性を提示した。

A multiple-treatments design was utilized to determine if the projected character prompt strategy was the most effective, followed by the character puppet prompt and the marker prompt. Results indicated that the marker prompt strategy and the projected character strategy were equally effective in helping the student to acquire table-wiping skills and more effective than the character puppet prompt strategy. However, the projected character prompt strategy elicited the most positive expressions and the fewest refusal behaviors. In contrast, the marker prompt strategy induced the fewest positive express ions and the most refusa l behaviors. en-copyright= kn-copyright= en-aut-name=MatsushitaYoshimasa en-aut-sei=Matsushita

要素（困難度，具体性，関与度，フィードバック），目標の整合性，そして部活動適応感を測定した。重回帰分析の結果，目標の整合性は，「活動への傾倒」と「組織・成員への満足」に正の効果を示した。また，集団目標の関与度も適応感を高める要因であった。さらに，整合性は目標要素の効果を調整していた。整合性が高い場合には個人目標への関与度が「活動への傾倒」を促進し，低い場合には集団目標のフィードバックが補完的に機能していた。これらの知見から，目標の整合性が，個人目標と集団目標の葛藤を緩和し，部活動における心理的適応を支える重要な要因であることが示唆された。

Japanese Society of Neuroendovascular Therapy: History and Current Status en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neuroendovascular therapy is a key treatment for cerebrovascular disorders, driven by advancements in devices and techniques. The Japanese Society for Neuroendovascular Therapy (JSNET) established a certification system in 1997 to ensure operator competence and minimize complications, with the first examination in 2002. JSNET offers 2 main certifications: specialist and instructor. Specialists perform basic procedures, while instructors lead in practice, education, and research. In 2020, the mechanical thrombectomy practitioner qualification was added to promote mechanical thrombectomy. Applicants must have a JSNET membership, relevant certifications, training, and documented experience. The certification process includes rigorous written and practical examinations that now employ non-fluoroscopic models. Certification renewal every 5 years requires conference participation and a continuing education program. Public awareness and integration into stroke center designations have grown. Over 2200 specialists, including more than 500 instructors, have been certified, significantly advancing neuroendovascular therapy in Japan. JSNET aims to continue improving certification and education to maintain high standards. en-copyright= kn-copyright= en-aut-name=YoshimuraShinichi en-aut-sei=Yoshimura en-aut-mei=Shinichi kn-aut-name=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study examines an OpenFOAM-based LES analysis from the viewpoints of inviscid energy conservation and viscous turbulence decay. The Smagorinsky model is employed as the sub-grid scale (SGS) model, and a two-dimensional periodic analytical solution and a three-dimensional periodic Taylor-Green vortex (TGV) are employed to represent inviscid flows. The analytical relationship for the kinetic energy K, dK/dt = 0, with t as the dimensionless time, is utilized to validate the OpenFOAM results. For the viscous flow case, the TGV flow in a three-dimensional periodic cubic domain is adopted, and its turbulence kinetic energy distribution is compared with that obtained by a spectral method to examine the analysis. The OpenFOAM-based analysis exhibits energy conservation error in flows that should ideally conserve energy. For the two-dimensional flow, this error decreases with increasing grid resolution N. However, in the three-dimensional flow, the error does not improve even with higher N. In the three-dimensional TGV flow, the turbulence kinetic energy predicted by OpenFOAM exhibits a strong agreement with that from the spectral method when a standard constant value of the Smagorinsky model is employed and the mesh is sufficiently refined. Conversely, for a condition of relatively coarse mesh, the decay characteristics of turbulent kinetic energy deviate from those of the spectral method, and a higher constant value of the Smagorinsky model than the default value becomes necessary to reproduce comparable results. These results suggests that even in LES simulations where highly accurate conservation laws are not satisfied, adjusting the model constants so that the predicted values match experimental or numerical reference data can improve the apparent reliability of the turbulent kinetic energy in the decaying turbulence. en-copyright= kn-copyright= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori 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= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Numerical simulation kn-keyword=Numerical simulation en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Energy conservation kn-keyword=Energy conservation en-keyword=Decaying turbulence kn-keyword=Decaying turbulence END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=3 article-no= start-page=179 end-page=187 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and applications of porous carbonaceous materials with inherited molecular structural features from the precursor molecules en-subtitle= kn-subtitle= en-abstract= kn-abstract=The carbonization of organic crystalline materials, such as metal organic frameworks and covalent organic frameworks, has emerged as a promising approach for producing functional porous carbonaceous materials. However, both the chemically defined long-term ordered structures and the local chemical structures derived from these precursor materials are generally lost, resulting in amorphous carbons. As a result, controlling the molecular-level structure of nanoporous carbons remains a significant challenge. We report a new bottom-up synthesis approach for porous carbons with a molecular-level design, involving the carbonization of well-designed precursor molecules by thermal polymerization. Among the resulting carbons, ordered carbonaceous frameworks, which contain a high-density of regularly aligned single-atomic metal species, have been identified as promising platforms for single-atom catalysts. This approach also enables the synthesis of various three-dimensional porous carbons that reflect the structural features of their precursor molecules. Recent progress in the synthesis and applications of porous carbons derived from molecular precursors is summarized, highlighting their potential for the development of functional materials. en-copyright= kn-copyright= en-aut-name=ChidaKoki en-aut-sei=Chida en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiTakeharu en-aut-sei=Yoshi en-aut-mei=Takeharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KamiyaKazuhide en-aut-sei=Kamiya en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoRyota en-aut-sei=Sakamoto en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgoshiTomoki en-aut-sei=Ogoshi en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishiharaHirotomo en-aut-sei=Nishihara en-aut-mei=Hirotomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= affil-num=2 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Center for Solar Energy Chemistry, Graduate School of Engineering Science, The University of Osaka kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Tohoku University kn-affil= affil-num=6 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=7 en-affil=Department of Synthetic Chemistry and Biological Chemistry, Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= en-keyword=Ordered carbonaceous frameworks (OCFs) kn-keyword=Ordered carbonaceous frameworks (OCFs) en-keyword=Porous carbon materials kn-keyword=Porous carbon materials en-keyword=Single-atom catalysts (SACs) kn-keyword=Single-atom catalysts (SACs) en-keyword=Catalyst supports kn-keyword=Catalyst supports END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=pgaf393 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chloroplast heat shock protein cpHsc70-1 interacts with thylakoid membrane remodeling protein VIPP1 C-terminal tail and controls VIPP1 oligomer assembly en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oxygenic photosynthetic organisms depend on the thylakoid membranes (TMs) for light-driven energy conversion. Recent studies on TM homeostasis (thylakostasis) have highlighted the essential role of the TM remodeling protein vesicle-inducing protein in plastid 1 (VIPP1). As a member of the endosomal sorting complexes required for transport-III (ESCRT-III)/phage shock protein A (PspA)/VIPP1 superfamily, VIPP1 forms large ring- and filament-like homo-oligomeric structures that exhibit a membrane remodeling activity. The oligomerization status was proposed to be modulated by the intrinsically disordered C-terminal tail (Vc), whereas its functional role remained unclear. Notably, this Vc region is conserved not only in photosynthetic VIPP1 but also in the PspA proteins of extremophilic species, implicating its role in membrane stress responses. To investigate the role of the Vc region in VIPP1 assembly, we performed coimmunoprecipitation assays in Arabidopsis chloroplasts and identified chloroplast-localized HSP70 proteins (cpHsc70) as major interactors. Among the two isoforms, cpHsc70-1 was found to be specifically required for modulating VIPP1 oligomeric assembly and dynamics in response to heat stress. Genetic analyses revealed that cpHsc70-1 facilitates the disassembly of VIPP1 oligomers, similarly to Vps4 ATPase in ESCRT-III; loss of either the Vc region or cpHsc70-1-impaired VIPP1 disassembly, resulting in more static oligomeric structures. Furthermore, cpHsc70-1 exhibited a broader role in chloroplast proteostasis, as the cphsc70-1 mutant showed impaired accumulation of green fluorescent protein (GFP)-fusion proteins. Together, our findings uncover a crucial crosstalk between proteostasis and thylakostasis in chloroplasts, coordinated by cpHsc70-1 and VIPP1 in response to membrane stress. en-copyright= kn-copyright= en-aut-name=LiDi en-aut-sei=Li en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GachieSarah Wanjiru en-aut-sei=Gachie en-aut-mei=Sarah Wanjiru 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=ScholzMartin en-aut-sei=Scholz en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=Institute of Plant Biology and Biotechnology, University of Münster kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=chloroplast kn-keyword=chloroplast en-keyword=heat shock protein kn-keyword=heat shock protein en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=thylakoid membrane remodeling kn-keyword=thylakoid membrane remodeling END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TeMPRA: advancing continuing professional development in pediatric rheumatology in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In the context of the global shortage of pediatric rheumatologists, mid-career specialists who can play key roles in regional education, research, and clinical practice have become increasingly important. In Japan, the Team of Mid-career Pediatric Rheumatologists Alliance (TeMPRA) was founded in 2014 to support continuing professional development (CPD) and foster collaboration among mid-career pediatric rheumatologists. The aim of this study was to characterize the current status and future perspectives of the TeMPRA members.
Methods In 2024, a cross-sectional, web-based survey was conducted among all 37 active members of the TeMPRA across Japan. Data were collected on career trajectories, educational roles, research activities, clinical practices, and international engagement. Categorical variables were compared using appropriate statistical tests, with a significance level of 0.05.
Results Responses were obtained from 35 members (response rate: 95%). Most respondents (71%) were affiliated with university hospitals, and 60% had > 10 years of experience in pediatric rheumatology. Compared with those working in community hospitals, respondents affiliated with university hospitals were significantly more likely to be involved in research activities (50% vs. 0%, P = 0.0261) and global professional contributions (88% vs. 0%, P < 0.0001). Overall, 54% of respondents were engaged in teaching students or early-career pediatric rheumatologists, while 43% were involved in clinical or basic research, most commonly focusing on juvenile idiopathic arthritis and systemic lupus erythematosus. Collectively, respondents were responsible for the care of 1,677 children with pediatric rheumatic diseases. While all respondents reported willingness to contribute to pediatric rheumatology at the regional level, 94% and 71% reported willingness to contribute at the national and global levels, respectively.
Conclusions This nationwide survey highlights the substantial educational roles, research activities, and clinical practices of mid-career pediatric rheumatologists in Japan and suggests that the TeMPRA framework can serve as a valuable model for supporting CPD and workforce sustainability. Similar alliance-based approaches may be applicable in other countries facing comparable challenges in pediatric rheumatology. en-copyright= kn-copyright= en-aut-name=WakiguchiHiroyuki

place-responsive climate change education: Mongolian primary teachers’ pedagogical judgement across urban and rural contexts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Climate change education (CCE) in primary schools is increasingly recognised as essential, yet how teachers interpret and enact CCE across diverse local contexts remains underexplored. This study examines how Mongolian primary school teachers working with students aged 6–11 in urban and rural contexts interpret and teach climate change, with particular attention to the role of place. Drawing on semi-structured interviews with 20 teachers across contrasting contexts, the study explores how environmental, cultural, and institutional conditions shape teachers’ pedagogical interpretations and classroom practices. Data were analysed using reflexive thematic analysis, informed by conceptual frameworks that position place as an active mediator of teaching and learning. Findings show that rural teachers frequently integrated traditional ecological knowledge and lived environmental experience to connect global climate processes with locally observable ecological change, emphasising livelihood impacts and intergenerational ecological memory. Urban teachers, by contrast, framed climate change through anthropogenic pressures such as air pollution, waste, and infrastructure constraints, foregrounding feasible individual actions within everyday school contexts. Across both settings, teachers exercised place-responsive pedagogical judgement by selectively adapting climate content to local realities while navigating curriculum constraints and workload pressures. The study contributes a place-responsive account of teachers’ pedagogical judgement in CCE, demonstrating how place functions not only as context but as a condition shaping pedagogical feasibility. en-copyright= kn-copyright= en-aut-name=GerelkhuuShinetsetseg en-aut-sei=Gerelkhuu en-aut-mei=Shinetsetseg kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Fiel’ardhKhalifatulloh en-aut-sei=Fiel’ardh en-aut-mei=Khalifatulloh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiHiroki en-aut-sei=Fujii en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YembuuBatchuluun en-aut-sei=Yembuu en-aut-mei=Batchuluun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DembereldorjUuriintuya en-aut-sei=Dembereldorj en-aut-mei=Uuriintuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=4 en-affil=Geography Department, Mongolian National University of Education kn-affil= affil-num=5 en-affil=Lifelong Learning and Distance Education Department, Mongolian National University of Education kn-affil= en-keyword=Climate change education kn-keyword=Climate change education en-keyword=place-responsive education kn-keyword=place-responsive education en-keyword=primary school teachers kn-keyword=primary school teachers en-keyword=pedagogical judgement kn-keyword=pedagogical judgement en-keyword=traditional ecological knowledge kn-keyword=traditional ecological knowledge en-keyword=urban–rural contexts kn-keyword=urban–rural contexts en-keyword=Mongolia kn-keyword=Mongolia END start-ver=1.4 cd-journal=joma no-vol=410 cd-vols= no-issue=1 article-no= start-page=171 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robotic distal pancreatectomy using two-surgeon technique (TAKUMI-4): a technical note and initial outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose With the increasing use of minimally invasive distal pancreatectomy, the use of robotic distal pancreatectomy (RDP) is also increasing worldwide. Standardized surgical protocols are essential for safe implementation of RDP. In this study, we present our surgical protocol and initial outcomes of RDP using “two-surgeon technique”.
Methods Our standard RDP protocol included a two-surgeon technique for cooperation, rationality, and education. Short-term outcomes of RDP were also investigated. This retrospective study included 77 consecutive patients who underwent RDP at our institution between April 2021 and January 2025.
Results The median operative time, estimated blood loss, and postoperative hospital stay were 214 min (interquartile range [IQR], 176–253), 10 mL (IQR, 0–50), and 9 days (IQR, 8–10), respectively. A textbook outcome was achieved in 84.4% of patients. Moreover, superior outcomes of RDP (n = 77) compared with those of laparoscopic distal pancreatectomy (n = 62) were confirmed in this study.
Conclusion Using the two-surgeon technique, we successfully standardized and introduced the RDP program. The two-surgeon technique can contribute to the safe introduction of RDP and expansion of the program. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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= en-keyword=Distal pancreatectomy kn-keyword=Distal pancreatectomy en-keyword=Robotic surgery: minimally invasive surgery kn-keyword=Robotic surgery: minimally invasive surgery en-keyword=Training kn-keyword=Training en-keyword=Outcomes kn-keyword=Outcomes END start-ver=1.4 cd-journal=joma no-vol=3027 cd-vols= no-issue=1 article-no= start-page=012009 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=LES analysis to investigate a random-phase forcing scheme for steadying anisotropic turbulence fields en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the effect of phase randomization on forcing mechanisms that stabilize localized turbulence. A trigonometric forcing based on vector potential is combined with uniform random numbers to create a spatially homogeneous forcing field. The analysis is performed using large-eddy simulation (LES) with the Smagorinsky model as the subgrid scale model. The results demonstrate that steady flows are generated regardless of the presence of phase randomization, successfully forming isotropic turbulence. In contrast, for anisotropic turbulent fields, the addition of phase randomization reduces the degree of anisotropy, indicating a smoothing effect on the anisotropy of the flow. en-copyright= kn-copyright= en-aut-name=MinamiKoki en-aut-sei=Minami en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroki en-aut-sei=Suzuki en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKento en-aut-sei=Tanaka en-aut-mei=Kento 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= END start-ver=1.4 cd-journal=joma no-vol=3027 cd-vols= no-issue=1 article-no= start-page=012008 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fundamental examination of coherent structure model prediction using vortex cores in a two-dimensional Taylor’s analytical solution en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study focuses on the possibility that flow around vortex tubes in turbulence may resemble laminar flow, and aims to describe the characteristics of turbulent fields using analytical solutions to the governing equations. In the two-dimensional analytical Taylor solution, the velocity and pressure fields are expressed by trigonometric functions, and a structure in which counter-rotating vortices are arranged in a grid pattern is demonstrated. This solution is used to verify the accuracy of numerical analyses and is expected to contribute to a simple yet unambiguous description of turbulent fields based on vortex structures. Predictions of sub-grid scale components and validation of a coherent structure model using invariants of the velocity gradient tensor are also performed. en-copyright= kn-copyright= en-aut-name=GongXuanyou en-aut-sei=Gong en-aut-mei=Xuanyou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroki en-aut-sei=Suzuki en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKento en-aut-sei=Tanaka en-aut-mei=Kento 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= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=209 end-page=226 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Teaching and Learning：Japanese and International Student Collaboration in the Classroom en-subtitle= kn-subtitle= en-abstract= kn-abstract=This practical report introduces three intercultural collaborative trial classes designed to integrate Japanese and international students in first-year EFL classes.

Post-course student surveys valued AI’s immediacy and capacity for elaboration, while also expressing concerns about dependence and limits to its effectiveness. Grade distributions showed a contraction of the lower-performing band after the introduction of the model, suggesting an overall uplift in learning outcomes. To counter misuse AI, explicit in-class instruction on constructive use, such as privileging diagnostic feedback over canned text and requiring metacognitive justification for accepting or rejecting AI suggestions, proved effective. We thus present the effectiveness and remaining challenges of a course design that leverages AI’s potential while keeping human judgment and ethics at its core. kn-abstract=本稿は、アカデミック・ライティング授業におけるピア・AI・教員のそれぞれの役割と利用順序（自分→ピア→AI→（省察）→教員）を組み込んだ三者協働モデルを設計し、2024～2025年度に実践した内容を報告する。授業後の学生アンケートでは、AIの即時性・精緻化が評価される一方、依存や有効性の限界に関する懸念も表明された。成績分布においては、AI導入後に下位層が縮小し、学習成果の底上げが示唆された。また、AI誤用や濫用を防ぐには、教室内で建設的な利用法の具体的な指導（例：例文より診断的フィードバックを重視、AI提案の採否理由のメタ記述）が効果的であった。これらの結果から、AIの利点を活かしつつ、学生の判断を中心に据えるライティング授業設計の有効性と課題を提示する。 en-copyright= kn-copyright= en-aut-name=UzukaMariko en-aut-sei=Uzuka en-aut-mei=Mariko kn-aut-name=宇塚万里子 kn-aut-sei=宇塚 kn-aut-mei=万里子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life kn-affil=教育推進機構 en-keyword=生成 AI kn-keyword=生成 AI en-keyword=アカデミック・ライティング kn-keyword=アカデミック・ライティング en-keyword=ピア評価 kn-keyword=ピア評価 en-keyword=メタ認知 kn-keyword=メタ認知 en-keyword=AI リテラシー kn-keyword=AI リテラシー END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=155 end-page=173 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An Attempt at Extensive Reading in Chinese at the Pre-Intermediate Level kn-title=大学における中国語多読の試み en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This study examines the implementation of the instruction for extensive reading in Chinese among 19 learners who completed one year of beginner-level Chinese studies comprising two 100-minute sessions per week.

Reconstructing the on-demand online course from a multicultural collaborative learning perspective required more than simply translating the materials into English. It also necessitated developing pedagogical strategies to foster collaborative learning in the online environment and to integrate linguistic and cultural considerations. kn-abstract=岡山大学では2025年4月入学生から新カリキュラムがスタートした。学士課程改革の一環として導入されたのが全学共通・課題探究科目「知の探研」である。本稿では，新入生対象科目である「知の探研」を，海外生を含むグローバル・ディスカバリー・プログラム生向けに英語で “Inquiries of Knowledge” として開講した初年度の取り組みを報告する。とりわけオンデマンド型オンライン授業を, 本学が推進する多文化共修の視点で再構築するにあたり，教材を単に英訳するのではなく, オンライン環境においても協働学習を実現する工夫や，言語的・文化的配慮の統合が不可欠であることを明らかにする。 en-copyright= kn-copyright= en-aut-name=YAMAMOTOYumiko en-aut-sei=YAMAMOTO en-aut-mei=Yumiko kn-aut-name=山本由美子 kn-aut-sei=山本 kn-aut-mei=由美子 aut-affil-num=1 ORCID= en-aut-name=NGUYENKha Manh en-aut-sei=NGUYEN en-aut-mei=Kha Manh kn-aut-name=グエン•カ•マン kn-aut-sei=グエン• kn-aut-mei=カ•マン aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of General and Global Studies (GDP), Okayama University kn-affil=岡山大学学術研究院 共通教育・グローバル領域（GDP） affil-num=2 en-affil=Discovery Program for Global Learners, Okayama University kn-affil=岡山大学グローバル・ディスカバリー・プログラム en-keyword=多文化共修 kn-keyword=多文化共修 en-keyword=協働学習 kn-keyword=協働学習 en-keyword=探究型学習 kn-keyword=探究型学習 en-keyword=オンデマンド型オンライン授業 kn-keyword=オンデマンド型オンライン授業 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=129 end-page=144 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Learner Narratives Based on Faculty-Specific Interviews and Orientation Practices：An Attempt to Enhance Foreign Language Learning Motivation at University Entrance kn-title=学部別インタビューによる学習者ナラティブとオリエンテーション実践 ―大学入学時における外国語学習動機づけ促進の試み― en-subtitle= kn-subtitle= en-abstract=Okayama University has implemented a comprehensive reform of its English curriculum as part of Target2025, a university-wide initiative launched in response to the new Course of Study issued by MEXT. The reform fosters close collaboration between the English section and other faculties to support undergraduate English learning across the university. We interviewed role models－successful English learners recommended by their faculties－about how they learned English. We also shared messages of encouragement for new students, which were recorded and shown during the orientation for English courses. This paper reviews the interview and orientation process, as well as first-year students’ responses to a subsequent survey. kn-abstract=岡山大学では新学習指導要領実施に合わせ、「学習者中心の学び」の実現を目指すTarget2025と呼ばれる方針のもと英語カリキュラムの改革を進めてきた。この改革では、英語系教員と各部局とが密に連携しながら、学士課程全体を通した英語学習を全学的に展開していくことに焦点を当てている。その取り組みの一環として、各部局から推薦を受けたロールモデルとの学部別インタビューを実施し、英語学習についての詳細を聴き取った。また、新入生への激励のメッセージ動画を作成し、英語授業オリエンテーションで上映した。本稿では、インタビューで得られたナラティブやオリエンテーション実施の経緯、また、オリエンテーション後に実施したアンケート結果について報告する。 en-copyright= kn-copyright= en-aut-name=YOSHIDAAzumi en-aut-sei=YOSHIDA en-aut-mei=Azumi kn-aut-name=吉田安曇 kn-aut-sei=吉田 kn-aut-mei=安曇 aut-affil-num=1 ORCID= en-aut-name=TERANISHIMasako en-aut-sei=TERANISHI en-aut-mei=Masako kn-aut-name=寺西雅子 kn-aut-sei=寺西 kn-aut-mei=雅子 aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 affil-num=2 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 en-keyword=学部別インタビュー kn-keyword=学部別インタビュー en-keyword=学習者ナラティブ kn-keyword=学習者ナラティブ en-keyword=ロールモデル kn-keyword=ロールモデル en-keyword=オリエンテーション kn-keyword=オリエンテーション en-keyword=動機づけ kn-keyword=動機づけ END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=120 end-page=128 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From The Odyssey to The Zahir：The Evolution of Penelopeia Across Time and Tradition en-subtitle= kn-subtitle= en-abstract= kn-abstract=The story of a man who leaves home and strives to return has become one of the most enduring narrative patterns in world literature and folklore. Across centuries and cultures, it has been retold in myths, epics, folktales, and modern fiction—the story of the homecoming hero who, after long absence and peril, finds his way back to the place and the person he once called his own. This study explores the persistence and transformation of this universal motif through a comparative reading of Homer’s The Odyssey and Paulo Coelho’s The Zahir. It examines the evolving image of the waiting wife—from Homer’s Penelopeia, emblem of chastity and endurance, to Coelho’s Esther, a modern woman of independence and choice. Despite differences in setting, voice, and moral vision, both works embody the same human longing: to return, to be recognized, and to rediscover love that endures time and change. Beneath their differences lies the same truth—the heart to which every journey, whether physical or spiritual, must ultimately return. en-copyright= kn-copyright= en-aut-name=KHALMIRZAEVASaida en-aut-sei=KHALMIRZAEVA en-aut-mei=Saida kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of General Education and Global Studies, Okayama University kn-affil= en-keyword=Homer kn-keyword=Homer en-keyword=The Odyssey kn-keyword=The Odyssey en-keyword=Paulo Coelho kn-keyword=Paulo Coelho en-keyword=The Zahir kn-keyword=The Zahir en-keyword=Penelopeia kn-keyword=Penelopeia END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=100 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Developing a Short-form Scale to Assess Learner Beliefs Regarding English Learning Strategies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Questionnaire surveys are a prevalent method in applied linguistics for investigating complex constructs, such as learner beliefs.

While reviewing prior research, this paper newly identifies two previously unnoted source textbooks: one published by Kinkōdō in 1894 and another by Fukyūsya in 1893. The findings indicate that the Meiji-period reader most frequently referenced in Chodeung-sohak was Jinjō Kokugo Tokuhon published by Kinkōdō in 1900. Overall, it can be concluded that Chodeung-sohak relied primarily on the comparatively recent elementary-level readers issued by Kinkōdō and the Ministry of Education. kn-abstract=　本稿では、近代韓国の読本教科書『初等小学』（1906）の編纂において参照されたと思われる日本の明治期読本教科書について比較・考察を行った。まず、文部省編纂の検定『尋常小学読本』（1887）と第1期国定『尋常小学読本』（1903）、さらに金港堂出版の『尋常国語読本』（1900）及び『高等国語読本』（1900）との関連性について、先行研究の議論を再検討した。そのうえで、新たに金港堂の『新体読本 尋常小学用』（1894）と普及舎の『尋常小学新読本』（1893）の2種を底本として確認することができた。『初等小学』において最も多く参照された明治期読本教科書は金港堂の『尋常国語読本』（1900）であり、『初等小学』は、金港堂と文部省の比較的新しい尋常小学用読本教科書を優先的に参照したと思われる。 en-copyright= kn-copyright= en-aut-name=LEEAnkoo en-aut-sei=LEE en-aut-mei=Ankoo kn-aut-name=李安九 kn-aut-sei=李 kn-aut-mei=安九 aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 en-keyword=『初等小学』 kn-keyword=『初等小学』 en-keyword=近代韓国の読本教科書 kn-keyword=近代韓国の読本教科書 en-keyword=明治期読本教科書 kn-keyword=明治期読本教科書 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=57 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Criteria for Faculty Decision-Making Regarding the Acceptance of International Students：From the perspective of faculty who accept many international students kn-title=留学生受け入れにおける教員の判断基準 ―多くの留学生を受け入れている教員の視点から― en-subtitle= kn-subtitle= en-abstract=　The declining birth rate significantly impacts domestic universities' enrolment, creating high expectations for increased international student intake. Within postgraduate education, however, a divide exists between faculty members who are and aren't proactive in accepting them. This study used semi-structured interviews to clarify the criteria faculty members use when accepting international students. The findings showed that while terminology varied, faculty commonly considered both “character” and “ability”. Furthermore, faculty who viewed international admissions positively had either studied or conducted research abroad and/or gained positive experiences from supervising their first international students. These factors fostered positive impressions and led to more proactive acceptance. kn-abstract=　少子化は国内大学の定員充足率に深刻な影響を与えることから、留学生の受入増に期待が寄せられている。しかし、大学院教育において留学生受入に前向きな教員と、消極的な教員が見受けられる。本研究では、より多くの留学生を受け入れている教員が、どのような判断基準で受け入れを決定しているのかを、半構造化インタビューを通じて明らかにすることを試みた。その結果、判断基準に関しては、教員により表現は異なるが「人物」と「能力」を確認していることが分かった。また、受け入れを前向きに考える教員は、留学・在外研究員経験や、初めて受け入れた留学生指導を通じて良い経験をしたこと等が、留学生に対するプラスの印象をつくり、積極的な受け入れにつながっていることが明らかになった。 en-copyright= kn-copyright= en-aut-name=INAMORITakao en-aut-sei=INAMORI en-aut-mei=Takao kn-aut-name=稲森岳央 kn-aut-sei=稲森 kn-aut-mei=岳央 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of General and Global Studies, Okayama University kn-affil=学術研究院共通教育・グローバル領域 en-keyword=日本留学 kn-keyword=日本留学 en-keyword=大学院 kn-keyword=大学院 en-keyword=留学生 kn-keyword=留学生 en-keyword=受入教員 kn-keyword=受入教員 en-keyword=判断基準 kn-keyword=判断基準 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=41 end-page=56 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Mediating Role of Self-Understanding in the Association Between Autistic Traits and Mental Health kn-title=自閉スペクトラム症特性と精神的健康の関連：自己理解による媒介効果の検討 en-subtitle= kn-subtitle= en-abstract=　This study examined whether positive and negative dimensions of self-understanding mediate the association between autistic traits and mental health in the general population.

This association was partially mediated by the positive dimension of self-understanding, whereas the negative dimension did not mediate. Exploratory analyses suggested that this protective effect may be more pronounced in women than in men. These findings identify positive self-understanding as an actionable target for support and underscore the value of gender-informed approaches. kn-abstract= 本研究は、自閉スペクトラム症特性と精神的健康の関連において、自己理解がどのような役割を果たすかを明らかにすることを目的とした。日本の成人604名のデータを利用した二次分析の結果、自閉スペクトラム症特性の高さと精神的健康の悪化との間には関連が認められた。この関連は、自己理解の肯定的側面によって部分的に媒介されることが示された。特にこの自己理解の保護的な効果は、男性よりも女性においてより強い可能性が示唆された。一方で、自己理解の否定的側面は媒介効果を示さなかった。これらの結果から、自閉スペクトラム症特性を持つ人々への支援において、肯定的な自己理解を促進することが重要であり、性差を考慮したアプローチの必要性が示唆された。 en-copyright= kn-copyright= en-aut-name=NISHIMURAHiroki en-aut-sei=NISHIMURA en-aut-mei=Hiroki kn-aut-name=西村大樹 kn-aut-sei=西村 kn-aut-mei=大樹 aut-affil-num=1 ORCID= en-aut-name=UCHIDAAkihiro en-aut-sei=UCHIDA en-aut-mei=Akihiro kn-aut-name=内田晃裕 kn-aut-sei=内田 kn-aut-mei=晃裕 aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 affil-num=2 en-affil=Okayama Psychiatric Medical Center kn-affil=地方独立行政法人岡山県精神科医療センター en-keyword=自閉スペクトラム症 kn-keyword=自閉スペクトラム症 en-keyword=メンタルヘルス kn-keyword=メンタルヘルス en-keyword=精神的健康 kn-keyword=精神的健康 en-keyword=自己理解 kn-keyword=自己理解 en-keyword=性差 kn-keyword=性差 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=31 end-page=40 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study of Participant Interaction in Online Volunteer Japanese Language Classes：Toward the Advancement of Community-Based Japanese Language Education kn-title=オンラインによるボランティア日本語教室における参加者間のインターアクションの分析 ―地域型日本語教育の実現に向けて― en-subtitle= kn-subtitle= en-abstract=This study investigates interactional dynamics within an online volunteer-based Japanese language classroom, with the aim of contributing to the development of a community-based instructional model.

The analysis yielded the following findings: (1) the mean number of utterances produced by supporters was greater than that of learners; and (2) the average amount of indirect behavior in supporters’ utterances by slightly exceeded that of direct behavior. In the interactive style, supporters were observed to actively employ subcategories of indirect behaviors—such as questioning, using ideas of learners, and repeating learner responses—in order to scaffold the learners’ process of verbalizing their intended messages. kn-abstract= 本研究では，地域型日本語教育のモデル構築に向け，地域型の特徴を有する教室内での支援者および参加者の発話や教授行動の傾向を明らかにすべく，外国語相互作用分析システムを用い，オンラインによるボランティア教室におけるインターアクションの分析を行った。分析の結果，（1）支援者の平均発話数が学習者より多いこと，（2）支援者の発話における間接的行動の割合が直接的行動よりもやや高いことが示された。「おしゃべり型の教育」では，学習者が伝えたいことを言語化していくプロセスの中で，間接的行動の下位分類の「質問」「学習者の意図の利用」「学習者の回答の繰り返し」等を支援者が積極的に使用し支援していることが分かった。 en-copyright= kn-copyright= en-aut-name=SUESHIGEMiwa en-aut-sei=SUESHIGE en-aut-mei=Miwa kn-aut-name=末繁美和 kn-aut-sei=末繁 kn-aut-mei=美和 aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 en-keyword=地域型日本語教育 kn-keyword=地域型日本語教育 en-keyword=おしゃべり型 kn-keyword=おしゃべり型 en-keyword=オンラインボランティア教室 kn-keyword=オンラインボランティア教室 en-keyword=F-システム kn-keyword=F-システム en-keyword=インターアクション kn-keyword=インターアクション END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=12 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical Psychologists’ Reflective Practice in Group Experiences kn-title=心理臨床家同士のグループ体験における反省的実践 en-subtitle= kn-subtitle= en-abstract=　Reflective practice is crucial for psychological clinicians, who participate in it in diverse group formats.

However, there are still uncertainties regarding their bioavailability. In this study, we investigated the bioavailability of 6 flavonoids, galangin, kaempferol, quercetin, myricetin, fisetin, and luteolin, by oral administration to mice. Analysis of plasma concentrations of free flavonoids after deconjugation by LC-MS/MS revealed that all flavonoids were rapidly absorbed after administration. Among 6 flavonoids, kaempferol and fisetin showed high absorbed amounts in blood plasma. With the LogP value of the two flavonoids as the maximum value, the amount absorbed decreased for both lower and higher LogP values. The results of the tissue distribution of galangin, kaempferol, and quercetin suggested that the order of fastest movement from the stomach to the small intestine was kaempferol > quercetin > galangin. In addition, the amount of kaempferol and quercetin distributed in the liver was greater than that of galangin. These results suggest that the bioavailability of flavonoids varies with the slight structural differences, possibly due to differences in their rapid accessibility to the small intestine that is the primary site of absorption and metabolism within the body. en-copyright= kn-copyright= en-aut-name=MaedaNozomi en-aut-sei=Maeda en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HashimotoAtsushi en-aut-sei=Hashimoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaRyosei en-aut-sei=Morita en-aut-mei=Ryosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Flavonoid kn-keyword=Flavonoid en-keyword=Bioavailability kn-keyword=Bioavailability en-keyword=Distribution kn-keyword=Distribution END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=2 article-no= start-page=023F01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feedback-Controlled Beam Pattern Measurement Method Using a Power-Variable Calibration Source for Cosmic Microwave Background Telescopes en-subtitle= kn-subtitle= en-abstract= kn-abstract=We demonstrate a novel beam pattern measurement method for the side lobe characterization of cosmic microwave background telescopes. The method employs a power-variable artificial microwave source under feedback control from the detector under test on the telescope. It enables us to extend the dynamic range of the beam pattern measurement without introducing nonlinearity effects from the detector. We conducted a laboratory-based proof-of-concept experiment, measuring the H-plane beam pattern of a horn antenna coupled to a diode detector at 81 GHz. We gained an additional dynamic range of 60.3 dB attributed to the feedback control. In addition, we verified the measurement by comparing it with other reference measurements obtained using conventional methods. The method is also applicable to general optical measurements requiring a high dynamic range to detect subtle nonidealities in the characteristics of optical devices. en-copyright= kn-copyright= en-aut-name=HiroseHaruaki en-aut-sei=Hirose en-aut-mei=Haruaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaMasaya en-aut-sei=Hasegawa en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanekoDaisuke en-aut-sei=Kaneko en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagasakiTaketo en-aut-sei=Nagasaki en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakuRyota en-aut-sei=Takaku en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=de HaanTijmen en-aut-sei=de Haan en-aut-mei=Tijmen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakakuraSatoru en-aut-sei=Takakura en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujinoTakuro en-aut-sei=Fujino en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Physics, Graduate School of Engineering Science, Yokohama National University kn-affil= affil-num=2 en-affil=Institute of Particle and Nuclear Studies (IPNS), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=3 en-affil=International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (WPI-QUP), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=4 en-affil=Accelerator Laboratory (ACCL), High Energy Accelerator Research Organization (KEK) 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=Institute of Particle and Nuclear Studies (IPNS), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=7 en-affil=Department of Physics, Faculty of Science, The University of Tokyo kn-affil= affil-num=8 en-affil=International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (WPI-QUP), High Energy Accelerator Research Organization (KEK) kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=24 article-no= start-page=4967 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An AI-Driven System for Learning MQTT Communication Protocols with Python Programming en-subtitle= kn-subtitle= en-abstract= kn-abstract=With rapid developments of wireless communication and Internet of Things (IoT) technologies, an increasing number of devices and sensors are interconnected, generating massive amounts of data in real time. Among the underlying protocols, Message Queuing Telemetry Transport (MQTT) has become a widely adopted lightweight publish–subscribe standard due to its simplicity, minimal overhead, and scalability. Then, understanding such protocols is essential for students and engineers engaging in IoT application system designs. However, teaching and learning MQTT remains challenging for them. Its asynchronous architecture, hierarchical topic structure, and constituting concepts such as retained messages, Quality of Service (QoS) levels, and wildcard subscriptions are often difficult for beginners. Moreover, traditional learning resources emphasize theory and provide limited hands-on guidance, leading to a steep learning curve. To address these challenges, we propose an AI-assisted, exercise-based learning platform for MQTT. This platform provides interactive exercises with intelligent feedback to bridge the gap between theory and practice. To lower the barrier for learners, all code examples for executing MQTT communication are implemented in Python for readability, and Docker is used to ensure portable deployments of the MQTT broker and AI assistant. For evaluations, we conducted a usability study using two groups. The first group, who has no prior experience, focused on fundamental concepts with AI-guided exercises. The second group, who has relevant background, engaged in advanced projects to apply and reinforce their knowledge. The results show that the proposed platform supports learners at different levels, reduces frustrations, and improves both engagement and efficiency. en-copyright= kn-copyright= en-aut-name=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao 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=Sandi KyawHtoo Htoo en-aut-sei=Sandi Kyaw en-aut-mei=Htoo Htoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PradhanaAnak Agung Surya en-aut-sei=Pradhana en-aut-mei=Anak Agung Surya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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 Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=7 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=IoT kn-keyword=IoT en-keyword=MQTT protocol kn-keyword=MQTT protocol en-keyword=AI-assisted learning kn-keyword=AI-assisted learning en-keyword=exercise-based education kn-keyword=exercise-based education en-keyword=Python programming kn-keyword=Python programming en-keyword=docker kn-keyword=docker en-keyword=learning platform kn-keyword=learning platform END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=39 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Kinesiophobia Is Associated with Disability, Poor Quality of Life, Psychological Morbidity, and Surgery Dissatisfaction in Patients with Lumbar Microdiscetomy: A Cross-Sectional Controlled Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study aimed to determine the prevalence of kinesiophobia in patients who had undergone lumbar microdiscectomy and to examine its associations with pain intensity, disability, quality of life, depression, anxiety, and satisfaction with surgery. Forty-eight patients with microdiscectomy and 48 healthy controls were enrolled. The Tampa Scale for Kinesiophobia (TSK), Roland-Morris Disability Index (RMDI), Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and Short Form-36 Health Survey (SF-36) were administered to both groups. The scores of TSK, RMDI, HADS-A, and HADS-D were significantly higher and SF-36 scores were significantly lower in the microdiscectomy than the control group (p<0.001 for all). In the microdiscectomy group, median (min-max) RMDI, HADS-A, and HADS-D scores were 19 (4-34), 10 (0-18), and 9 (0-18), respectively, in kinesiophobic patients, and were significantly higher than 6 (2-20), 3 (0-11), 2.5 (0-11) in non-kinesiophobic patients (all p<0.001). The median (min-max) SF-36 PCS, SF-36 MCS, and VAS scores for surgery satisfaction were 36.5 (8.7-75), 52.1 (11-95), 5, 5 (0-10), respectively, in kinesiophobic patients and were significantly lower than 71 (28-95), 85.5 (9-93), 8.5 (3-10) in non-kinesiophobic patients (all p<0.05). TSK scores were significantly correlated with RMDI, HADS-A, HADS-D, SF-36, and surgery satisfaction scores (all p<0.05). Kinesiophobic patients with lumbar microdiscectomy therefore showed greater disability and psychological morbidity, poorer quality of life, and lower satisfaction with surgery. en-copyright= kn-copyright= en-aut-name=TezelNihal en-aut-sei=Tezel en-aut-mei=Nihal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CanAslı Gençay en-aut-sei=Can en-aut-mei=Aslı Gençay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Physical and Rehabilitation Medicine, Health Sciences University kn-affil= affil-num=2 en-affil=Department of Physical and Rehabilitation Medicine, Faculty of Medicine, Ankara Yıldırım Beyazıt University kn-affil= en-keyword=kinesiophobia kn-keyword=kinesiophobia en-keyword=microdiscectomy kn-keyword=microdiscectomy en-keyword=disability kn-keyword=disability en-keyword=quality of life kn-keyword=quality of life en-keyword=depression kn-keyword=depression 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=2026 dt-pub=20260119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A retrospective cohort study comparing periodontal regeneration using fibroblast growth factor‐2 versus autologous bone graft en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Fibroblast growth factor-2 (FGF-2) is a novel agent utilized in periodontal regeneration therapy. However, its clinical efficacy compared with autologous bone graft (ABG), a long-established treatment, remains unclear. This study aimed to compare the clinical outcomes of FGF-2 and ABG and to assess the impact of patient background factors on outcomes when using FGF-2.
Methods: We collected the subjects from January 2013 to September 2023. Clinical outcomes included the vertical bone defect improvement rate (VBDIR) and the probing pocket depth improvement (PPDI). Clinical outcomes between the two groups were compared using analysis of covariance (ANCOVA), adjusting for age, sex, smoking history, and hypertension. Additionally, a multilevel linear analysis was performed to assess factors influencing outcomes in FGF-2.
Results: A total of 180 sites from 141 patients (FGF-2: 150 sites; ABG: 30 sites) were evaluated. Both VBDIR and PPDI significantly improved postoperatively in both groups. There were no significant differences in clinical outcomes between FGF-2 and ABG. In FGF-2, smoking history was positively associated, while the preoperative bone defect angle (BDA) was negatively associated with clinical outcomes.
Conclusions: FGF-2 might exhibit clinical outcomes comparable to those of ABG, suggesting it is a clinically viable alternative for vertical bone defects. When using FGF-2, patient-specific factors such as smoking history and preoperative BDA should be considered carefully.

Electromyography and Machine Learning en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: This study aimed to evaluate the potential use of machine learning to automatically classify electromyography (EMG) data into bruxism simulated movement with tooth contact (BMwTC), bruxism simulated movement without tooth contact (BMwoTC), and non-bruxism movement (non-BM).
Methods: Twelve eligible healthy participants (female/male: 2/10, mean age: 35.3 ± 8.4 years) were asked to perform the simulated movements (all the tasks were performed five times for 5 s each with a 30-s rest interval). The electrodes were placed on the masseter, infrahyoid, inframandibular, and chin muscles. A sound sensor was placed adjacent to the masseter. The EMG and sound data were sampled at 1 and 44.1 kHz, respectively. Single- and multi-stream hidden Markov models (HMMs) were used to automatically discriminate the tested behavior from the others using a hamming window with 100 ms and shift length of 50 ms. The leave-one-out method was used for training and testing the model, with data from 11 participants used for training and one for testing. Each participant was evaluated, and the final performance was measured by averaging the results of 12 classification trials. The validity of the discrimination was assessed by calculating the harmony mean values using six EMG signals and the sound data.
Results: The masseter EMG demonstrated significantly higher discrimination accuracy in the single-stream model (p  < 0.05, One-way ANOVA, Tukey HDS). The multi-stream model also demonstrated higher accuracy; however, no significant difference was observed. Notably, the accuracy of BMwoTC was less than 0.5.
Conclusion: The machine-learning-based discriminative system accurately discriminates BMwTC from non-BM using masseter EMG. en-copyright= kn-copyright= en-aut-name=MinakuchiHajime en-aut-sei=Minakuchi en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagasakiMitsuhiro en-aut-sei=Nagasaki en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ĐìnhLộc Hoàng en-aut-sei=Đình en-aut-mei=Lộc Hoàng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiHaruna en-aut-sei=Miki en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OmoriKo en-aut-sei=Omori en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishimuraTazuko en-aut-sei=Nishimura en-aut-mei=Tazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinematsuNobuaki en-aut-sei=Minematsu en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo kn-affil= en-keyword=bruxism kn-keyword=bruxism en-keyword=dentistry kn-keyword=dentistry en-keyword=electromyography kn-keyword=electromyography en-keyword=EMG discrimination kn-keyword=EMG discrimination en-keyword=machine learning kn-keyword=machine learning END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=12 article-no= start-page=e095428 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of education programme to increase competency of health cadres in Indonesia: a cluster non-randomised controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives Health cadres, who assist midwives in supporting pregnant women in community settings, need to enhance their competencies in identifying risk factors and referring high-risk pregnant women to midwives for further care. Since the capabilities of these health cadres are influenced by maternal complications, an educational programme was implemented to strengthen their skills. Therefore, this study aimed to evaluate the competency of health cadres by providing a researcher-developed educational programme.
Design An open-label, cluster non-randomised controlled trial.
Setting and participants Health cadres with at least 1 year of work experience were recruited at six public health centres (PHCs) in Banjarnegara Regency, Indonesia.
Interventions Six PHCs were selected and allocated into intervention group (IG=3 PHCs) and control group (CG=3 PHCs) groups. A total of 133 female health cadres were enrolled across the selected PHCs. At each PHC, a systematic random sampling method was used to select the participants. The researchers and health professionals provided a 3-week period of theoretical and scenario-based simulations to the IG, while the CG received no education.
Outcome measures Researcher-developed questionnaires and checklists were used to assess the knowledge, skills (health assessment, communication, attitude) and confidence. The primary endpoint was competency, a total score of knowledge and skills. The outcome domains were compared between the two groups, and a linear mixed-effect model was used to account for cluster-level variation.
Results A total of 130 (97.7%) completed the study (IG:64, CG:66). The competency score showed significant improvement at endline (CG=49.5 and IG=52.5; p=0.002). The median scores for health assessment skills (CG=12 vs IG=14; p<0.001) and communication skills (CG=7 vs IG=8; p<0.001) were increased in the IG compared with the CG. Mixed-effect model indicated that groups (β (95% CI) 2.49 (0.57 to 4.41), p=0.012), baseline knowledge (β(95% CI) 0.73 (0.54 to 0.92), p<0.001) and midline health assessment skills (β (95% CI) 0.54 (0.25 to 0.82), p<0.001) were significant positive predictors, while age was negatively associated with competency (β (95% CI) −0.20 (−0.30 to −0.10), p<0.001)).
Conclusion Education effectively increased the competency of health cadres. A well-structured education programme is necessary for health cadres to improve and maintain their competencies in monitoring high-risk pregnant women.

However, conventional methods for identifying neoantigens, such as whole-exon sequencing and short-read RNA sequencing (RNA-seq), appear to be insufficient, and the tumor mutational burden cannot sufficiently predict ICI efficacy. In this study, we employed a proteogenomic approach using long-read RNA-seq with Pacific Biosciences Single-Molecule Real-Time Sequencing technology to analyze full-length transcripts in combination with the human leukocyte antigen ligandome. As a result, many neoantigen candidates were identified, which were unregistered in a comprehensive database, including those from non-coding regions. Additionally, we validated the responses of specific T cell receptors (TCRs) to these candidates and identified several pairs of TCRs and neoantigens. These findings highlight the presence of more diverse neoantigens than expected that cannot be identified by conventional methods. en-copyright= kn-copyright= en-aut-name=IshinoTakamasa

Matching Analysis (2016–2023) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Candidemia is a life-threatening infection with high mortality, and appropriate management is essential to improve patient outcomes. The Candida Care Bundle aims to standardize hospital management for patients with candidemia and reduce mortality.
Methods. This retrospective multicenter cohort study included candidemia cases from 9 hospitals in Japan between 2016 and 2023. Compliance to the Candida Care Bundle was evaluated based on 5 elements: central venous catheter removal within 24 hours, appropriate antifungal therapy, ophthalmologic examination, follow-up blood cultures, and antifungal treatment for ≥2 weeks after clearance. Patients were categorized into high (4–5 items) and low (0–3 items) compliance groups. The primary and secondary outcomes were defined as 30-day survival and the development of endophthalmitis, with propensity score matching used to adjust for potential confounders.
Results. Among 230 patients, 160 (69.5%) were classified into the high compliance group, which exhibited significantly lower 30-day mortality than the low compliance group (8.8% vs 57.1%, P < .01). Even after matching, the high compliance group remained independently associated with improved survival (hazard ratio [HR]: 0.15; 95% confidence interval [CI]: .08–.30). C. albicans (HR: 1.95; 95% CI: 1.01–3.52) and central line-associated bloodstream infection (HR: 2.63; 95% CI: 1.35–5.12) were associated with the fatal outcome. Endophthalmitis involved 23.6% of the patients, being associated with C. albicans (odds ratio [OR]: 8.18; 4.46–19.30) and central line-associated bloodstream infection (OR: 2.69; 1.08–6.70).
Conclusions. Strict compliance to the Candida Care Bundle significantly improves survival, underscoring its importance in candidemia management. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiToshie en-aut-sei=Higuchi en-aut-mei=Toshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko 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=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkamatsuYukinobu en-aut-sei=Akamatsu en-aut-mei=Yukinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarukiYuto en-aut-sei=Haruki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamotoYoshitaka en-aut-sei=Iwamoto en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShuichi en-aut-sei=Tanaka en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujisatoShun en-aut-sei=Fujisato en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkoSoichiro en-aut-sei=Ako en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Internal Medicine, Okayama Red Cross Hospital kn-affil= affil-num=4 en-affil=Center for Medical Education and Internationalization, Kyoto University Graduate School of Medicine 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=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Medicine, Tottori Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, NHO Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama Rousai Hospital 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 Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=candida bundle kn-keyword=candida bundle en-keyword=candidemia kn-keyword=candidemia en-keyword=endophthalmitis kn-keyword=endophthalmitis en-keyword=prognosis kn-keyword=prognosis en-keyword=propensity score matching kn-keyword=propensity score matching END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page=9991157 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knowledge and Attitudes Toward Pain Management Among Nurses in University-Affiliated Hospitals in Western Japan: A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pain is a major global concern. Nurses’ knowledge and attitudes toward pain management are critical determinants of pain care quality and patient outcomes, making them essential for effective clinical practice.
Objective: This study aimed to assess nurses’ pain management knowledge and attitudes using the Japanese version of the Knowledge and Attitudes Survey Regarding Pain (J-KASRP), applied for the first time in Japan, and to examine how background factors affect these aspects.
Methods: A descriptive, cross-sectional survey was conducted with 1589 nurses in three university-affiliated hospitals in Western Japan. Data were collected using a questionnaire capturing sociodemographic information and the J-KASRP. Descriptive statistics, t-tests, one-way ANOVA, and effect size were used to analyze J-KASRP scores and subdomains. Tukey’s honestly significant difference test was applied for post hoc comparisons across clinical experience patterns.
Results: Of 1001 respondents, 856 valid responses (85.5%) were analyzed. The mean age was 30.1 years (SD = 8.3), and the mean total correct response rate for the J-KASRP was 59.8%; only 1.3% scored ≥ 80%. Cancer-related pain had the lowest J-KASRP subdomain score (42.5%, SD = 20.3%). Higher total J-KASRP scores were found for those with a higher level of education, prior clinical pain education, and recent opioid administration experience (all p < 0.001, effect size > 0.2). In an exploratory pattern analysis, regardless of education level, respondents with both education and opioid administering experience had the highest total and pharmacology subdomains’ scores. No significant differences in cancer-related pain subdomain were observed across patterns of clinical experiences.
Conclusions: This first application of the J-KASRP in Japan revealed that nurses’ pain management knowledge and attitudes need to be strengthened, especially for cancer-related pain and opioid pharmacology. The study findings highlight the importance of pain management strengthening education and training to enhance nurses’ evidence-based knowledge and clinical competence. en-copyright= kn-copyright= en-aut-name=XiMengyao en-aut-sei=Xi en-aut-mei=Mengyao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KajiwaraYuki en-aut-sei=Kajiwara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiramatsuTakako en-aut-sei=Hiramatsu en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University, kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nursing, Kawasaki Medical School Hospital kn-affil= affil-num=4 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=knowledge andattitudes kn-keyword=knowledge andattitudes en-keyword=nurses kn-keyword=nurses en-keyword=painmanagement kn-keyword=painmanagement END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=6 article-no= start-page=660 end-page=671 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250914 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electronic Structure of the S1 State Manganese Cluster in Photosystem II Investigated Using Q-Band Selective Hole-Burning en-subtitle= kn-subtitle= en-abstract= kn-abstract=The electronic structure of the S1 state of photosystem II (PSII) was investigated using selective hole burning of Q-band pulsed electron paramagnetic resonance. The free induction decay and spin–echo signals of the tyrosine radical YD• in the plant PSII oscillated because of the magnetic dipole–dipole interaction with the S1 state Mn cluster. The initial period was 410 ns (2.44 MHz) and was assigned to the S = 1 spin state. Based on the oscillation analysis, both Mn1 and Mn4 and both Mn2 and Mn3 were assigned as Mn(III) and Mn(IV), respectively, which is consistent with the quantum chemical calculations. The 410 ns period was accounted for in the simplified model using the isotropic spin density distribution ratio [1.6:–1.1:–1.1:1.6] for Mn1–4 ions. This oscillation was identical with that observed in the presence of methanol. The oscillation decreased in PsbP/Q- and PsbO/P/Q-depleted PSII. In Thermosynechococcus vulcanus, two periods, 390 ns (2.56 MHz) and 630 ns (1.59 MHz), were detected, indicating that the cyanobacterial S1 state includes two isomers, S = 1 and S ≥ 2 spins. The S ≥ 2 spin was not detected in PsbO/U/V-depleted PSII without polyethylene glycol. The S ≥ 2 state was consistent with the reported quantum chemical calculation using S = 3. A simplified model accounted for the S = 1 state as the spin density distribution [1.8:–1.3:–1.3:1.8] and for the S ≥ 2 state as the isotropic spin density distribution [−0.5:0.5:0.5:0.5] for Mn1–4 ions. In combination with quantum chemical calculations, the most probable protonated structure is W1 = H2O, W2 = H2O, O4 = O2–, and O5 = O2– for the S1 state. These results demonstrate that the selective hole burning method is a powerful tool to complement X-ray studies to determine the valence and protonation structure of manganese clusters, not only in the S1 state but also in higher S-states and general metal clusters, which would provide important insights into the water oxidation mechanism. en-copyright= kn-copyright= en-aut-name=KosakiShinya en-aut-sei=Kosaki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraNaohiko en-aut-sei=Nakamura en-aut-mei=Naohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=MinoHiroyuki en-aut-sei=Mino en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Physics, Graduate School of Science, Nagoya University kn-affil= affil-num=2 en-affil=Department of Physics, Graduate School of Science, Nagoya University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Physics, Graduate School of Science, Nagoya University kn-affil= en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=Oxygen evolution kn-keyword=Oxygen evolution en-keyword=S1 state kn-keyword=S1 state en-keyword=Mn cluster kn-keyword=Mn cluster en-keyword=EPR kn-keyword=EPR en-keyword=Selective hole-burning kn-keyword=Selective hole-burning END start-ver=1.4 cd-journal=joma no-vol=190 cd-vols= no-issue=6 article-no= start-page=90 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic Value of Serum (1→3)-β-D-Glucan Levels in Patients with Candidemia Stratified by Compliance with Candida Bundle: A Multicenter Retrospective Cohort Study (2016–2023) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Candidemia is a severe systemic infection with a high mortality risk. While β-D-glucan (BDG) serves as a diagnostic biomarker, its prognostic value in candidemia, particularly in association with Candida bundle compliance, remains unclear.
Methods In this retrospective multicenter cohort study, we evaluated 96 patients with candidemia across nine Japanese hospitals between 2016 and 2023. Candida bundle compliance was assessed using five key components: central venous catheter removal within 24 h of diagnosis, appropriate initial antifungal therapy, ophthalmologic examination, follow-up blood cultures until clearance, and antifungal therapy for at least two weeks post-clearance. Analyses stratified patients by serum BDG status (positive/negative) and compliance with the Candida bundle (high: 4–5 points; low: 0–3 points). The primary outcome was 30-day mortality, and the secondary outcome was defined as endophthalmitis incidence.
Results Of 96 eligible patients with candidemia, 70 (72.9%) were BDG-positive and 26 (27.1%) were BDG-negative. The overall 30-day mortality was 17.7%. Among BDG-positive patients, 15 (21.4%) died, while 2 (7.7%) died in BDG-negative cohorts (p = 0.09). Serum BDG positivity demonstrated a statistically significant association with decreased survival rates in the low bundle adherence group (p = 0.02), whereas this correlation was not observed among patients in the high-compliance cohort (p = 0.66). Endophthalmitis occurred in 25.0% of patients, without significant correlation to serum BDG status. C. albicans was associated with a significantly higher incidence of endophthalmitis compared with non-albicans species (45.7% vs. 8.9%).
Conclusions Serum BDG positivity potentially correlates with worse survival in candidemia, particularly in patients with low bundle compliance. This emphasizes the importance of adherence to standardized Candida management protocols for optimizing patient outcomes. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiToshie en-aut-sei=Higuchi en-aut-mei=Toshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko 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=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkamatsuYukinobu en-aut-sei=Akamatsu en-aut-mei=Yukinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarukiYuto en-aut-sei=Haruki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamotoYoshitaka en-aut-sei=Iwamoto en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShuichi en-aut-sei=Tanaka en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujisatoShun en-aut-sei=Fujisato en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkoSoichiro en-aut-sei=Ako en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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 Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Internal Medicine, Okayama Red Cross Hospital kn-affil= affil-num=4 en-affil=Center for Medical Education and Internationalization, Kyoto University Graduate School of Medicine 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=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Medicine, Tottori Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, NHO Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama Rousai Hospital 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 Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Candidemia kn-keyword=Candidemia en-keyword=Prognosis kn-keyword=Prognosis en-keyword=β-D-glucan kn-keyword=β-D-glucan en-keyword=Candida bundle kn-keyword=Candida bundle en-keyword=Endophthalmitis kn-keyword=Endophthalmitis END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=9 article-no= start-page=e0329451 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of COVID-19 on the awareness and interest in infectious disease specialization among Japanese medical students en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The SARS-CoV-2 pandemic has highlighted the critical deficiency of infectious disease (ID) specialists, a subspecialty that remains underrepresented among Japanese medical students.
Methods
This nationwide cross-sectional survey was administered between April and August 2024 via an online questionnaire distributed to medical students throughout Japan. The survey assessed awareness of and interest in ID specialization, categorizing students by academic year: lower (first- and second-year students), middle (third- and fourth-year students), and upper grades (fifth- and sixth-year students).
Results
Of 502 respondents, data for 492 medical students were eligible, of whom 69.7% demonstrated awareness of ID specialists, with recognition rates increasing proportionally with academic progression. Regarding career aspirations, 9.8% of respondents expressed interest in pursuing ID specialization, with the highest proportion observed among upper-grade students (19.4%). Male students (14.8%) expressed greater interest in ID specialization than female students (5.2%). The pandemic positively influenced 5.5% of students to consider ID specialization as a future career, whereas only 0.6% reported a negative impact.
Conclusions
These findings underscore the necessity of enhanced educational initiatives to promote ID specialization among medical students, addressing current shortages and future infectious disease preparedness. en-copyright= kn-copyright= en-aut-name=KamadaNaruto en-aut-sei=Kamada en-aut-mei=Naruto 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=KutsunaSatoshi en-aut-sei=Kutsuna en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Medicine, Wakayama Medical University kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infection Control and Prevention, Graduate School of Medicine, Osaka University kn-affil= END
