Medullary cast formation has been shown to predict adverse renal outcomes beyond cortical interstitial fibrosis and tubular atrophy (IFTA), although its clinical determinants are not fully understood. We examined the associations of urine pH with kidney outcomes and medullary cast formation in patients undergoing native kidney biopsy. Methods: Among 1167 adults who underwent native kidney biopsy between 2011 and 2024, 503 patients with evaluable medullary tissue were included. Urine pH was analyzed in relation to clinical and histological variables and kidney outcomes. The primary outcome was a ?40% decline in estimated glomerular filtration rate (eGFR) or initiation of renal replacement therapy. Results: Mean baseline eGFR was 60.7 ± 26.2 mL/min/1.73 m2 and urine pH was 6.15 ± 0.84. During a median follow-up of 2.11 years, 113 patients (22.5%) reached the outcome. Lower urine pH was associated with higher risk of kidney outcomes. In multivariable Cox models, urine pH remained independently associated with outcomes (hazard ratio per 1-unit increase, 0.69; 95% CI, 0.52?0.92). Addition of urine pH modestly improved discrimination (C-index 0.642 to 0.654; likelihood ratio test, p = 0.009). Lower urine pH was associated with greater medullary cast formation in unadjusted analysis. Conclusions: Lower urine pH was independently associated with adverse kidney outcomes and with greater medullary cast formation, suggesting that urine pH may reflect intratubular pathological changes associated with CKD progression. en-copyright= kn-copyright= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueYoshitaka en-aut-sei=Inoue en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, 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 Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=urine pH kn-keyword=urine pH en-keyword=kidney outcomes kn-keyword=kidney outcomes en-keyword=medullary casts kn-keyword=medullary casts en-keyword=global glomerulosclerosis kn-keyword=global glomerulosclerosis en-keyword=interstitial fibrosis and tubular atrophy kn-keyword=interstitial fibrosis and tubular atrophy END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=5 article-no= start-page=327 end-page=332 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=Ruptured Intrahepatic Arterial Aneurysm due to Segmental Arterial Mediolysis Treated with Coil Embolization en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 67-year-old man presented with sudden-onset abdominal pain and hemorrhagic shock. Contrast-enhanced CT revealed a large hematoma in hepatic segments VI-VII with capsular rupture and hemoperitoneum. CT angiography demonstrated a saccular pseudoaneurysm in a posterior segmental branch of the right hepatic artery and a beaded appearance with irregular dilatation and segmental narrowing of the right hepatic artery branches, without inflammatory or atherosclerotic findings, supporting a diagnosis of segmental arterial mediolysis (SAM). Emergency angiography followed by coil embolization achieved hemostasis. Follow-up CT at 5 months showed complete exclusion of the aneurysmal lesions, with no evidence of recurrence or new vascular lesions. Coil embolization may be an effective, minimally invasive option for ruptured intrahepatic SAM lesions. en-copyright= kn-copyright= en-aut-name=HataYurika en-aut-sei=Hata en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TabuchiMotoyasu en-aut-sei=Tabuchi en-aut-mei=Motoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoShinya en-aut-sei=Sakamoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraShuta en-aut-sei=Tamura en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UemuraSunao en-aut-sei=Uemura en-aut-mei=Sunao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TokumaruTeppei en-aut-sei=Tokumaru en-aut-mei=Teppei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimatuRika en-aut-sei=Yoshimatu en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Radiology, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=segmental arterial mediolysis kn-keyword=segmental arterial mediolysis en-keyword=hepatic artery kn-keyword=hepatic artery en-keyword=intra-abdominal hemorrhage kn-keyword=intra-abdominal hemorrhage END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=5 article-no= start-page=309 end-page=316 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=Dynamics of Serum Amyloid A Levels in the Blood, Brain and Liver in a Mouse Model of Focal Cerebral Ischemia en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the dynamics of serum amyloid A (SAA) levels in the blood, brain, and liver over time using a mouse model of focal cerebral ischemia induced by occlusion of the middle cerebral artery (MCA) for 4 h followed by reperfusion. Blood SAA concentrations increased transiently after cerebral infarction, coinciding with changes in brain and liver SAA gene expression and protein levels. SAA concentrations in the brain, liver, and blood increased at similar time points after cerebral infarction, suggesting that SAA may serve as an important indicator of the associated pathological condition. en-copyright= kn-copyright= en-aut-name=EgashiraSaki en-aut-sei=Egashira en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakanoTakafumi en-aut-sei=Nakano en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieKeiichi en-aut-sei=Irie en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ManabeAkiko en-aut-sei=Manabe en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasakiAyuko en-aut-sei=Masaki en-aut-mei=Ayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MukaiRie en-aut-sei=Mukai en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraYoshihiko en-aut-sei=Nakamura en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HosokawaMasato en-aut-sei=Hosokawa en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SathoTomomitsu en-aut-sei=Satho en-aut-mei=Tomomitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SanoKazunori en-aut-sei=Sano en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MishimaKenichi en-aut-sei=Mishima en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=2 en-affil=Department of Oncology and Infectious Disease Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=3 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=4 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=5 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=6 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Microbiology Laboratory, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=8 en-affil=Department of Emergency and Critical Care Medicine, Fukuoka University Hospital kn-affil= affil-num=9 en-affil=Department of Immunological and Molecular Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=10 en-affil=Department of Microbiology Laboratory, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=11 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=12 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= en-keyword=stroke kn-keyword=stroke en-keyword=cerebral ischemia kn-keyword=cerebral ischemia en-keyword=serum amyloid A kn-keyword=serum amyloid A en-keyword=temporal dynamics kn-keyword=temporal dynamics END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=5 article-no= start-page=299 end-page=308 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=Prognostic Value of Combined Preoperative CALLY and SII Assessment in Patients Undergoing Resection for Esophageal Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study evaluated the prognostic significance of the C-reactive protein?albumin?lymphocyte (CALLY) index and systemic immune-inflammation (SII) index in predicting postoperative outcomes in patients with esophageal squamous cell carcinoma (ESCC). A retrospective analysis was performed on clinical data from 102 patients with ESCC who underwent surgical resection at Western Theater General Hospital of China between January 2020 and July 2023. The associations between preoperative CALLY and SII indices and relapse-free survival (RFS) and overall survival (OS) were examined. Survival curves were generated using the Kaplan?Meier method, and prognostic factors were identified using Cox proportional hazards regression analysis. Patients with a high CALLY index had significantly longer RFS (HR=0.30, 95% CI: 0.13-0.71), and those with a low SII index also had significantly longer RFS (HR=2.23, 95% CI: 1.12-4.41). Similarly, patients with a high CALLY index had significantly longer OS (HR=0.27, 95% CI: 0.13-0.55), and those with a low SII index had significantly longer OS (HR=2.27, 95% CI: 1.09-4.71). When patients were stratified into four groups, the low-CALLY?high-SII group showed significantly shorter RFS than the high-CALLY?low-SII group (HR=0.26, 95% CI: 0.11-0.61; p=0.013), and OS was also significantly worse in the low-CALLY?high-SII group (HR=0.22, 95% CI: 0.09-0.54; p=0.016). Univariate Cox regression analysis identified both CALLY and SII as significant prognostic factors. In multivariate analysis, the CALLY index and N stage were independently associated with RFS, whereas only tumor size remained independently associated with OS. The combined assessment of preoperative CALLY and SII indices may be useful for prognostic stratification in patients with ESCC undergoing upfront surgical resection. It may help identify high-risk patient subgroups with distinct survival outcomes, thereby providing a potential rationale for stratifying postoperative surveillance and tailoring individualized adjuvant strategies, although validation in larger prospective cohorts is warranted. en-copyright= kn-copyright= en-aut-name=XuTao en-aut-sei=Xu en-aut-mei=Tao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhengYing en-aut-sei=Zheng en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HuangXuemei en-aut-sei=Huang en-aut-mei=Xuemei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LuoHong en-aut-sei=Luo en-aut-mei=Hong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Oncology, The General Hospital of Western Theater Command kn-affil= affil-num=2 en-affil=Department of Oncology, The General Hospital of Western Theater Command kn-affil= affil-num=3 en-affil=Department of Oncology, The General Hospital of Western Theater Command kn-affil= affil-num=4 en-affil=Department of Oncology, The General Hospital of Western Theater Command kn-affil= en-keyword=CALLY index kn-keyword=CALLY index en-keyword=SII index kn-keyword=SII index en-keyword=esophageal squamous cell carcinoma kn-keyword=esophageal squamous cell carcinoma en-keyword=prognosis kn-keyword=prognosis END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=5 article-no= start-page=289 end-page=298 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=High Accuracy of Pelvic Tilt Measurement Using Three-Dimensional Planning Software: A Validation Study Using Dry Bone Models en-subtitle= kn-subtitle= en-abstract= kn-abstract=The “CR Alignment” function was recently introduced in ZedHip?, the hip joint module of ZedView?, to evaluate pelvic tilt in non-supine positions via two-dimensional (2D)?3D matching using radiographs. However, its ccuracy has not been validated. This study therefore evaluated the accuracy of pelvic tilt measurements using the CR Alignment function in dry pelvic bone specimens. Two cadaveric pelvic bone models were placed in nine orientations (anterior/posterior tilt and left/right rotation). Both radiographic and CT images were acquired in each position. In Study 1, pelvic tilt measured directly from CT images was defined as the “true value.” Three observers used the CR Alignment function to calculate pelvic tilt on radiographs, and measurement errors were determined relative to the true values. In Study 2, measurement errors were compared between matched (same position) and mismatched (different position) imaging. In Study 1, the mean measurement error was 1.28±0.64°. Intra- and interobserver intraclass correlation coefficients were 0.996-0.998 and 0.997, respectively. In Study 2, the mean errors were 1.20±0.88° (matched) and 1.32±1.03° (mismatched). This software exhibited high accuracy and reproducibility in 2D?3D matching of pelvic tilt, with lower variability under matched acquisition, demonstrating its utility for pre- and postoperative assessment in joint arthroplasty. en-copyright= kn-copyright= en-aut-name=KomutaYuki en-aut-sei=Komuta en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HommaDaisuke en-aut-sei=Homma en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FunayamaKazuhisa en-aut-sei=Funayama en-aut-mei=Kazuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiranoYuki en-aut-sei=Hirano en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MinatoIzumi en-aut-sei=Minato en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawashimaHiroyuki en-aut-sei=Kawashima en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Orthopedic Surgery, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=2 en-affil=Division of Comprehensive Musculoskeletal Medicine, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=3 en-affil=Division of Orthopedic Surgery, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=4 en-affil=Division of Legal Medicine, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=5 en-affil=Division of Orthopedic Surgery, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=6 en-affil=Division of Comprehensive Musculoskeletal Medicine, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Niigata Rinko Hospital kn-affil= affil-num=8 en-affil=Division of Orthopedic Surgery, Graduate School of Medical and Dental Sciences, Niigata University kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=pelvic tilt kn-keyword=pelvic tilt en-keyword=three-dimensional planning software kn-keyword=three-dimensional planning software en-keyword=two-dimensional and threedimensional matching kn-keyword=two-dimensional and threedimensional matching en-keyword=radiographic analysis kn-keyword=radiographic analysis END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=5 article-no= start-page=279 end-page=288 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=Diabetes Mellitus as a Risk Factor for Severe COVID-19 and Pneumonia: A Comparison Between the Pre-Omicron and Omicron-Dominant Periods in Okayama City, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diabetes mellitus is a well-established risk factor for severe COVID-19; however, few studies have examined this association during the Omicron-dominant period. We conducted a population-based study using surveillance data from the Okayama City Public Health Center in Japan to compare the risk of severe COVID-19 and pneumonia among patients with diabetes mellitus between the pre-Omicron (March 2020?December 2021) and Omicron-dominant (January?September 2022) periods. Among 98,905 COVID-19 patients aged 10 years or older, we calculated adjusted odds ratios (aORs) controlling for age, sex, smoking status, comorbidities, obesity, and the number of COVID-19 vaccine doses received. In the pre-Omicron period, diabetes mellitus was significantly associated with severe COVID-19 (aOR: 1.36; 95% CI: 1.03-1.78), and this association persisted in the Omicron-dominant period (aOR: 1.54; 95% CI: 1.10-2.17). Similar findings were observed for pneumonia. The association was more pronounced among patients aged 40-69 years than among those aged 70 years or older. These findings suggest that diabetes mellitus remains an important risk factor for severe COVID-19 even during the Omicron-dominant period, highlighting the need for continued clinical vigilance and early intervention in patients with diabetes mellitus. en-copyright= kn-copyright= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi 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=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=Omicron variant kn-keyword=Omicron variant en-keyword=severity kn-keyword=severity en-keyword=population-based study kn-keyword=population-based study END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=5 article-no= start-page=271 end-page=277 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=Artificial Intelligence-Assisted Peroral Cholangioscopy for the Diagnosis and Management of Biliary Strictures: Current Evidence and Future Directions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peroral cholangioscopy (POCS) enables direct intraductal visualization and targeted biopsies for indeterminate biliary strictures. However, its diagnostic performance remains operator-dependent and is limited by sampling error. As artificial intelligence (AI) has rapidly advanced in gastrointestinal endoscopy, AI-assisted cholangioscopy has progressed from proof-of-concept image classification to multicenter validation, feature detection, and real-time application. Recent studies using digital single-operator cholangioscopy have reported diagnostic accuracy comparable to that of experts in differentiating malignant from benign strictures, and feature-based approaches can automatically detect tumor vessels and other key visual characteristics. Beyond classification, generative models may enhance mucosal and margin visualization through virtual chromoendoscopy, potentially improving lesion-margin assessment. Furthermore, new models compatible with multiple systems are emerging to address device heterogeneity, which is a key barrier to routine practice.

Modern crop production faces mounting challenges such as climate change, emerging diseases, and shifting quality demands, creating an urgent need for breeding approaches that enable more precise genetic improvement within shorter timeframes. Targeted mutagenesis capable of introducing mutations accurately and efficiently began with the development of meganucleases and subsequently evolved through ZFNs, TALENs, and CRISPR/Cas systems. Recent technological advances, including multiplex editing and DNA-free genome editing, have made direct modification of elite cultivars increasingly feasible, helping to overcome long-standing barriers associated with genotype dependency and the complexity of polyploid genomes. Targeted mutagenesis has now been applied to a wide range of breeding targets, including disease resistance, tolerance to abiotic stresses, yield-related traits, and quality traits. Moreover, machine learning and AI are beginning to support target selection and phenotype prediction, ushering in an era in which genome editing can be integrated into breeding programs more rationally and efficiently. These scientific developments coincide with regulatory shifts in many countries toward easing restrictions on new genomic techniques (NGTs), particularly by treating SDN-1 genome-edited crops equivalently to those produced through conventional breeding. Such changes are expected to accelerate field trials, commercialization, and international collaboration. Nevertheless, several challenges remain, including bottlenecks in transformation efficiency, off-target assessment, the control of complex traits, societal acceptance, and unresolved regulatory details. Even so, genome editing is poised to become a central technology in next-generation cereal breeding, enabling the development of cultivars with greater resilience, productivity, and adaptability to diverse industrial needs. en-copyright= kn-copyright= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=CRISPR/Cas9 kn-keyword=CRISPR/Cas9 en-keyword=genome editing kn-keyword=genome editing en-keyword=Hordeum vulgare kn-keyword=Hordeum vulgare en-keyword=plant breeding kn-keyword=plant breeding en-keyword=transformation amenability kn-keyword=transformation amenability END start-ver=1.4 cd-journal=joma no-vol=340 cd-vols= no-issue=1 article-no= start-page=31 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and structural analysis of 6-deoxy-6-hydroxyphosphinyl-d-fructopyranose derivatives en-subtitle= kn-subtitle= en-abstract= kn-abstract=3,4-Di-O-benzyl-6-deoxy-6-diethoxyphosphinyl-1,2-O-isopropylidene-β-d-fructofuranose (13) was prepared from the known 1,2-O-isopropylidene-6-O-tosyl-β-d-fructofuranose in five steps.

Reducing lignin content in barley grain and straw is beneficial for improving forage digestibility and enhancing the efficiency of bioethanol production. The orange lemma mutation?characterized by orange pigmentation of husks and nodes?has long been associated with altered lignin metabolism; however, its genetic basis has remained unclear. We show that Cinnamyl Alcohol Dehydrogenase (CAD) is the causal gene underlying the orange lemma phenotype in barley. Genetic mapping using a ‘Haruna Nijo’?×?‘L053’ F? population and the Barley 50 K SNP array defined a candidate region on chromosome 6H containing the CAD gene. Sequence analysis revealed that all orange lemma mutants, including both naturally occurring and EMS-induced lines, carried nucleotide changes in the CAD gene, resulting in amino acid substitutions or premature stop codons. Furthermore, CRISPR/Cas9-mediated knockout of CAD in the cultivar ‘Golden Promise’ reproduced the orange lemma phenotype, providing functional validation. The knockout plants also showed significantly lower lignin content than wild-type plants. These findings resolve a long-standing question regarding the genetic basis of the orange lemma trait and demonstrate that disruption of CAD alters lignin accumulation in barley. This work provides a valuable genetic resource for breeding barley cultivars with improved biomass utilization for feed and bioenergy applications. en-copyright= kn-copyright= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaMaho en-aut-sei=Morita en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamajiNami en-aut-sei=Yamaji en-aut-mei=Nami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakoRinka en-aut-sei=Kako en-aut-mei=Rinka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UshijimaTomokazu en-aut-sei=Ushijima en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Graduate School of Agricultural Science, Setsunan University kn-affil= affil-num=5 en-affil=Graduate School of Agricultural Science, Setsunan University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Cinnamyl Alcohol Dehydrogenase (CAD) kn-keyword=Cinnamyl Alcohol Dehydrogenase (CAD) en-keyword=Barley kn-keyword=Barley en-keyword=Orange lemma kn-keyword=Orange lemma en-keyword=Lignin kn-keyword=Lignin en-keyword=Genome editing kn-keyword=Genome editing END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=3 article-no= start-page=1525 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bioinformatic Prediction of Activation States in Molecular Network Pathways of Eukaryotic Initiation Factor 2 (EIF2) Signaling and Coronavirus Pathogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eukaryotic initiation factor 2 (EIF2) signaling plays a crucial role in regulating mRNA translation and initiating eukaryotic protein synthesis. Computational molecular network pathway analysis of the canonical pathways of the coronaviral infection revealed that EIF2 signaling is inactivated when the coronavirus pathogenesis pathway is activated and vice versa. Our computational analyses indicated that the coronavirus pathogenesis pathway and EIF2 signaling had inverse activation states. Computational investigation of upstream or downstream microRNA (miRNA) revealed that EIF2 signaling directly interacted with miRNAs, including let-7, miR-1292-3p (miRNAs with the seed CGCGCCC), miR-15, miR-34, miR-378, miR-493, miR-497, miR-7, miR-8, and MIRLET7. A total of 36 nodes, including 8 molecules (ATF4, BCL2, CCND1, DDIT3, EIF2A, EIF2AK3, EIF4E, and ERK1/2), 1 complex (the ribosomal 40s subunit), and 1 function (apoptosis) in the coronavirus pathogenesis pathway, overlapped with EIF2 signaling. Alterations in EIF2 signaling may play a role in the pathogenesis of coronavirus. en-copyright= kn-copyright= en-aut-name=TanabeShihori en-aut-sei=Tanabe en-aut-mei=Shihori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=QuaderSabina en-aut-sei=Quader en-aut-mei=Sabina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoRyuichi en-aut-sei=Ono en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaHiroyoshi Y. en-aut-sei=Tanaka en-aut-mei=Hiroyoshi Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CabralHoracio en-aut-sei=Cabral en-aut-mei=Horacio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Risk Assessment, Center for Biological Safety and Research, National Institute of Health Sciences kn-affil= affil-num=2 en-affil=Innovation Centre of NanoMedicine (iCONM), Kawasaki Institute of Industrial Promotion kn-affil= affil-num=3 en-affil=Division of Cellular and Molecular Toxicology, Center for Biological Safety and Research, National Institute of Health Sciences kn-affil= affil-num=4 en-affil=Department of Pharmaceutical Biomedicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Bioengineering, Graduate School of Engineering, The University of Tokyo kn-affil= en-keyword=coronavirus kn-keyword=coronavirus en-keyword=EIF2 signaling kn-keyword=EIF2 signaling en-keyword=microRNA kn-keyword=microRNA en-keyword=molecular pathway kn-keyword=molecular pathway en-keyword=network activation kn-keyword=network activation 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=20261005 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Experimental evolution of female mating responses to infertile males in Tribolium castaneum en-subtitle= kn-subtitle= en-abstract= kn-abstract=In many animal populations, infertile males?those unable to reproduce?are commonly present. If females mate exclusively with such males, they fail to produce offspring. How, then, do females deal with this situation? Distinguishing infertile from fertile males both before and after copulation is difficult for females. Here, we tested the hypothesis of bet-hedging polyandry, in which females mitigate the risk of reproductive failure by mating with multiple males, using experimental evolution in the red flour beetle (Tribolium castaneum). Females were cohabited with males artificially sterilized by sublethal radiation and with untreated males at a 1:1 ratio (sterile:untreated). After more than 15 generations, females from the treatment strains did not avoid mating with infertile males, leading to reduced reproductive success. However, compared with the control strains, females from the treated strains tended to mate with a greater number of males. The results raise the possibility that increased polyandry (mating with multiple males) may evolve rather than relying on pre- or post-copulatory discrimination to mitigate the risk posed by infertile males. Bet-hedging is a strategy that spreads or minimizes risk under uncertainty, and these results are consistent with the hypothesis that polyandry can function as a bet-hedging strategy against uncertain male fertility. en-copyright= kn-copyright= en-aut-name=FujiiYui en-aut-sei=Fujii en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsanoYui en-aut-sei=Asano en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoriKenta en-aut-sei=Kori en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiYukio en-aut-sei=Yasui en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HimuroChihiro en-aut-sei=Himuro en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamotoYutaka en-aut-sei=Nakamoto en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SokeiYoshitaka en-aut-sei=Sokei en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Faculty of Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Arts and Sciences, The University of Tokyo kn-affil= affil-num=5 en-affil=Faculty of Agriculture, Kagawa University kn-affil= affil-num=6 en-affil=Okinawa Prefectural Plant Protection Center kn-affil= affil-num=7 en-affil=Okinawa Prefectural Plant Protection Center kn-affil= affil-num=8 en-affil=Okinawa Prefectural Plant Protection Center kn-affil= affil-num=9 en-affil=Faculty of Environmental, Natural Science and Technology, Okayama University kn-affil= en-keyword=Beetle kn-keyword=Beetle en-keyword=Bet-hedging kn-keyword=Bet-hedging en-keyword=Copulation kn-keyword=Copulation en-keyword=Matingbehavior kn-keyword=Matingbehavior en-keyword=Reproductive failure kn-keyword=Reproductive failure END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=742 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260914 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= 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= cd-vols= no-issue= article-no= start-page=1 end-page=6 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=A Novel Iterative Method for Principal Component Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Principal Component Analysis (PCA) is a statistical method used for identifying key patterns from a given dataset and reducing its dimensions, while retaining most of the original information.

In this paper, we propose a novel iterative method for PCA, which is expressed as a system of nonlinear difference equations. Unlike the power method, the proposed method can obtain the specified number of principal components in parallel.

Here, we show that delta morphology on Mars records a shift between these hydrologic regimes. Through controlled tank experiments, we identify two distinct delta types: “lobe-extruding deltas” formed during water-level falls and “stepped fan-deltas” formed during rising water levels. The lobe-extruding deltas occur near proposed paleo-coastlines and are dated to ~3.8?3.2 Ga, consistent with the existence of a Late Noachian?Hesperian ocean and its subsequent regression in the Late Hesperian. In contrast, stepped fan-deltas are found at a wider range of elevations and exhibit significantly younger ages (~2.1?0.1 Ga), suggesting episodic, localized lake formation during the Amazonian. Our findings constrain the timing of the planetary-scale transition from a global hydrosphere to localized aqueous environments and refine the understanding of Mars’ paleoclimate evolution and potential habitability. en-copyright= kn-copyright= en-aut-name=KitoRen en-aut-sei=Kito en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaHitoshi en-aut-sei=Hasegawa en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RujTrishit en-aut-sei=Ruj en-aut-mei=Trishit kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MutoTetsuji en-aut-sei=Muto en-aut-mei=Tetsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OriGian Gabriele en-aut-sei=Ori en-aut-mei=Gian Gabriele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomatsuGoro en-aut-sei=Komatsu en-aut-mei=Goro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Science and Technology, Kochi University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Department of Environmental Science, Nagasaki University kn-affil= affil-num=5 en-affil=International Research School of Planetary Sciences, Universit? d’Annunzio kn-affil= affil-num=6 en-affil=International Research School of Planetary Sciences, Universit? d’Annunzio kn-affil= END start-ver=1.4 cd-journal=joma no-vol=248 cd-vols= no-issue= article-no= start-page=117443 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Molecular characteristics and clinical outcomes of ERBB2-activating mutation-positive non-small cell lung cancer: A Japanese nationwide real-world cohort en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Erb-b2 receptor tyrosine kinase 2 (ERBB2)-activating mutations are well-documented oncogenic drivers in non-small cell lung cancer (NSCLC), occurring in approximately 1?4% of cases. These alterations include a heterogeneous spectrum of variant subtypes; however, the clinicogenomic characteristics and clinical significance of the individual variants have yet to be elucidated.
Methods: We searched the nationwide Center for Cancer Genomics and Advanced Therapeutics database, which integrates comprehensive genome profiling data generated in routine clinical practice across Japan, to investigate the molecular landscape and clinical outcomes of patients with ERBB2-mutated NSCLC.
Results: A total of 319 patients with ERBB2-activating mutations were included in this retrospective analysis. Although 74% of the patients harbored canonical tyrosine kinase domain (TKD) in-frame insertions, 26% carried noncanonical variants, including TKD missense (8%), transmembrane/juxtamembrane domain (10%), and extracellular domain (ECD) mutations (8%). Co-occurring oncogenic driver alterations were identified in only 18 cases (5.6%) and were largely restricted to noncanonical variants, whereas no co-occurring driver alterations were detected among patients with TKD in-frame mutations. Noncanonical variants?TKD missense and ECD mutations in particular?were associated with an increased tumor mutational burden. Among 288 patients with available survival data, 78 (27%) received trastuzumab deruxtecan (T-DXd) during their clinical course. After excluding patients who had started treatment with T-DXd before undergoing comprehensive genome profiling testing, time-dependent T-DXd exposure was associated with a reduced risk of death (adjusted hazard ratio, 0.63; 95% confidence interval, 0.39?1.01; P?=?0.057).
Conclusions: ERBB2-mutated NSCLC exhibited substantial molecular heterogeneity, with canonical TKD in-frame insertions characterized by a low frequency of co-occurring oncogenic driver alterations. Among patients harboring ERBB2-activating mutations, exposure to T-DXd was associated with improved overall survival. en-copyright= kn-copyright= en-aut-name=YamashitaMasahiro en-aut-sei=Yamashita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritaAyako en-aut-sei=Morita en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaraNaofumi en-aut-sei=Hara en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakadaKenji en-aut-sei=Takada en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KuboToshio en-aut-sei=Kubo en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=14 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= en-keyword=ERBB2 mutation kn-keyword=ERBB2 mutation en-keyword=Variant subtype kn-keyword=Variant subtype en-keyword=Comprehensive genomic profiling kn-keyword=Comprehensive genomic profiling en-keyword=Trastuzumab-deruxtecan kn-keyword=Trastuzumab-deruxtecan en-keyword=Non-small cell lung cancer kn-keyword=Non-small cell lung cancer END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=17 article-no= start-page=3880 end-page=3890 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260526 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sequential Immune Activation of Effector T Cells as Biomarkers of Response to Durvalumab in Patients with Locally Advanced NSCLC en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Durvalumab therapy following concurrent chemoradiotherapy (cCRT) improves progression-free survival (PFS) in patients with unresectable locally advanced non?small cell lung cancer. In this prospective observational study, we evaluated the changes in peripheral blood immune cell counts to elucidate the immunologic mechanisms underlying cCRT and durvalumab therapy.
Experimental Design: Peripheral blood mononuclear cell (PBMC) samples were collected at four time points: before cCRT, after cCRT, at the start of durvalumab, and 8 weeks after the start of durvalumab, and analyzed by multicolor flow cytometry.
Results: Of the 149 enrolled patients, 115 received durvalumab consolidation therapy after cCRT. The median PFS in the overall population was 24.2 months, and the 3-year PFS rate was 38.9%. PBMC analysis showed an increased effector fraction of CD4+ T cells before and after cCRT but no change in CD8+ T cells. Following durvalumab therapy, the effector fraction ratio of CD8+ T cells (CD62Llow CD8+ T cells) increased and positively correlated with increased CD62Llow CD4+ T cells during cCRT. Patients whose proportion of CD62Llow CD4+ T cells exceeded the threshold for cCRT had better PFS than those below the threshold. Patients whose CD62Llow CD8+ T-cell proportion exceeded the threshold after durvalumab therapy showed prolonged PFS compared with those below the threshold.
Conclusions: cCRT promotes an increase in effector CD4+ T cells, and the subsequent increase in CD8+ T cells following durvalumab therapy prolongs PFS. Peripheral blood effector?type CD4+ and CD8+ T cells are potential biomarkers for evaluating the immune status of patients and predicting treatment efficacy. en-copyright= kn-copyright=

target to delay drug tolerance to EGFR?TKIs in an EGFR-mutant non-small cell lung cancer model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The presence of drug-tolerant persister (DTP) cells reduces the effectiveness of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) in EGFR-mutated non-small cell lung cancer (NSCLC). Although autophagy is a potential target for eliminating DTP cells, clinical trials targeting autophagy in EGFR-mutant NSCLC have been unsuccessful?likely because most trials have utilized chloroquine, non-specifically inhibiting autophagy targeting lysosomes with dose limitations. This study focused on unc-51-like autophagy activating kinase 1 (ULK1), a more specific target for autophagy inhibition, to assess whether ULK1 inhibition delays the emergence of tolerance to EGFR-tyrosine kinase inhibitors in EGFR-mutant NSCLC cells.
Methods: DTP cells were generated by treating EGFR-mutant NSCLC cell lines with osimertinib. Autophagy status and ULK1 expression were evaluated using immunofluorescence, western blotting, and quantitative real-time PCR. The effects of both pharmacological and genetic inhibition of ULK1 were examined in vitro and in vivo.
Results: ULK1 and LC3-II, markers of autophagy, were upregulated in DTP cells. Inhibition of ULK1, either pharmacologically or genetically, suppressed autophagy, prevented the formation of DTP cells, and enhanced the antitumor activity of osimertinib in both in vitro and in vivo models. Furthermore, upregulation of ULK1 expression through serum starvation conferred tolerance to osimertinib, reinforcing ULK1′s role in drug tolerance. Notably, ULK1 inhibition showed modest efficacy even after cells transitioned to the DTP or acquired resistance states.
Conclusion: ULK1 plays a critical role in mediating drug tolerance in EGFR-mutant NSCLC. Targeting ULK1 represents a promising therapeutic approach to enhance the efficacy of EGFR-TKIs and to delay the development of drug tolerance. en-copyright= kn-copyright= en-aut-name=MoritaAyako en-aut-sei=Morita en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RaiKammei en-aut-sei=Rai en-aut-mei=Kammei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuribayashiTadahiro en-aut-sei=Kuribayashi en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiTatsuya en-aut-sei=Nishi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaraNaofumi en-aut-sei=Hara en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KuboToshio en-aut-sei=Kubo en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OchiNobuaki en-aut-sei=Ochi en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences 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 Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Internal Medicine 4, Kawasaki Medical School kn-affil= affil-num=13 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= en-keyword=ULK1 kn-keyword=ULK1 en-keyword=Autophagy kn-keyword=Autophagy en-keyword=EGFR kn-keyword=EGFR en-keyword=TKI kn-keyword=TKI en-keyword=Osimertinib kn-keyword=Osimertinib en-keyword=Non-small cell lung cancer kn-keyword=Non-small cell lung cancer END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=6 article-no= start-page=315 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260527 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Limited Immune-Mediated Efficacy of Anti-PD-L1/VEGF in EGFR-TKI-Na?ve Egfr-Mutant Lung Cancer with Non-Inflamed Tumor Microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs) show limited efficacy in epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma due to its non-inflamed tumor microenvironment (TME). While quadruple therapy combining chemotherapy, anti-programmed death-ligand 1 (PD-L1), and anti-vascular endothelial growth factor (VEGF) antibodies has shown inconsistent results in EGFR-tyrosine kinase inhibitor (TKI)-pretreated patients, whether anti-VEGF therapy can modulate the intrinsic non-inflamed TME remains unknown. We employed an EGFR-TKI-na?ve syngeneic Egfr-mutant mouse model and evaluated effects of anti-VEGF, anti-PD-L1, carboplatin, and paclitaxel as monotherapies and combinations, with TME analysis via immunohistochemistry (IHC), flow cytometry, and RNA sequencing. Anti-PD-L1 showed no antitumor effect, and adding anti-VEGF failed to convert the TME to an inflamed status. Although paclitaxel?but not carboplatin?combined with low-dose anti-VEGF inhibited tumor growth, adding anti-PD-L1 provided no benefit, indicating the anti-VEGF-A antibody evaluated here has a limited role in sensitizing tumors to anti-PD-L1 regardless of chemotherapy. CD8+ T-cell depletion did not attenuate the effect of paclitaxel plus low-dose anti-VEGF, and IHC and RNA sequencing revealed increased natural killer cell infiltration, suggesting a CD8+ T-cell-independent, innate immune mechanism. These findings provide preclinical evidence that the evaluated anti-VEGF has limited immunomodulatory activity in EGFR-TKI-na?ve Egfr-mutant tumors with a non-inflamed TME, and suggest immunotherapeutic strategies beyond CD8+ T-cell-mediated immunity warrant investigation. en-copyright= kn-copyright= en-aut-name=HirabaeAtsuko en-aut-sei=Hirabae en-aut-mei=Atsuko kn-aut-name=

Lung Disease in Patients With Unresectable Stage III NSCLC Treated With Chemoradiotherapy Followed by Durvalumab in Japan: Analysis From the Multicenter Prospective AYAME Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Interstitial lung disease (ILD) is a concerning adverse event associated with immune checkpoint inhibitors, including durvalumab. This analysis of the multicenter AYAME study assessed the longterm safety of durvalumab, focusing on ILD.
Methods: AYAME enrolled patients prescribed durvalumab for unresectable stage III non-small cell lung cancer (NSCLC) after chemoradiotherapy (CRT) from July 2019 to December 2020 in Japan. Patients received durvalumab for ??12?months and were prospectively followed for 3?years. Incidence, severity, and management of ILD were examined. Multivariable logistic regression analysis was conducted to investigate the association of patient characteristics with grade ??2 ILD occurrence.
Results: Of 511 patients in the safety analysis population, ILD occurred in 383 patients (75.0%) from durvalumab initiation to subsequent treatment start; median time to occurrence was 44.0?days. ILD led to permanent durvalumab discontinuation in 121/383 patients (31.6%), dose interruption in 111/383 (29.0%), and corticosteroid intervention in 168/383 (43.9%). Grade ??2 ILD occurrence was higher in patients with volume of lung parenchyma that received 20?Gy (V20) ??25% versus Conclusions: This study of durvalumab for NSCLC after CRT in a real-world setting indicated factors associated with grade ??2 ILD and provided valuable insights into ILD management strategies. These findings may contribute to establishing effective approaches to minimize ILD risk in practice.

However, few large-scale studies have prospectively evaluated its long-term effectiveness and safety, including subsequent treatment.
Methods: This multicenter, noninterventional study (AYAME) enrolled patients who were prescribed durvalumab for unresectable stage III NSCLC after CRT (July 2019?December 2020; 52 sites; Japan). Patients received durvalumab for a maximum of 12 months and were prospectively followed up for 3 years, including the post-durvalumab treatment period. Primary end points were real-world progression-free survival (rwPFS), the incidence of interstitial lung disease (ILD), and adverse events of special interest (AESIs).
Results: Of the 529 enrolled patients, 512 received durvalumab and 511 comprised the safety analysis population. The median time to onset of the first presentation or occurrence of ILD was 45.0 days. ILD of any grade occurred in 387 patients (75.7%) over the 3-year study period: grade 3, 57 (11.2%); grade 4, none (0.0%); and grade 5, 9 (1.8%). The most common AESIs of any grade during durvalumab treatment were thyroid dysfunction (12.5%), hepatic dysfunction (7.2%), and colitis (2.0%). No durvalumab treatment-related ILD or AESIs occurred during the post-treatment period. The median [95% confidence interval] rwPFS was 23.2 [18.2, 27.2] months in the effectiveness analysis population (n = 495). rwPFS rates were 62.5%, 54.6%, 49.4%, and 40.4% at 12, 18, 24, and 36 months, respectively.
Conclusions: This first and largest prospective, observational study demonstrated the long-term safety and effectiveness of durvalumab for unresectable stage III NSCLC after CRT in a real-world clinical setting.

Case 1 involved a 59-year-old woman with a nodular shadow in the left upper pulmonary field observed on chest radiography. Chest computed tomography (CT) scan revealed a nodule in the left upper lobe and a soft tissue tumor near the left third rib. Given her elevated plasma progastrin-releasing peptide (ProGRP) level, a CT-guided biopsy was performed, confirming a diagnosis of pulmonary carcinoid with solitary bone metastasis. She subsequently underwent partial resection of the left upper lobe and the rib tumor. Case 2 involved a 67-year-old woman referred to our hospital after a chest CT scan revealed a nodule in the left lingular region. Her plasma ProGRP level was elevated, and a CT-guided biopsy confirmed a diagnosis of pulmonary carcinoid. As no lymph node metastases were detected, she underwent segmental resection of the left upper lobe. In both cases, plasma ProGRP levels decreased following surgical resection. These findings suggest that plasma ProGRP levels may serve as a useful diagnostic marker for pulmonary carcinoids. en-copyright= kn-copyright= en-aut-name=YamaokaTakashi en-aut-sei=Yamaoka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NoumiTaku en-aut-sei=Noumi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoChiaki en-aut-sei=Matsumoto en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugimotoKeisuke en-aut-sei=Sugimoto en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= affil-num=4 en-affil=Department of Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= affil-num=5 en-affil=Department of Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= en-keyword=biopsy kn-keyword=biopsy en-keyword=case report kn-keyword=case report en-keyword=progrp kn-keyword=progrp en-keyword=pulmonary carcinoid kn-keyword=pulmonary carcinoid en-keyword=tumor marker kn-keyword=tumor marker END start-ver=1.4 cd-journal=joma no-vol=234 cd-vols= no-issue= article-no= start-page=112260 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The eukaryotic host?microbe?phage?nutrition interplay determines the bacterial effectors of supplemental lysine’s health benefits: An experimental cellular senescence model of digestive conditions in older adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, the consumption of various forms of the nutritive amino acid lysine (e.g., nutraceuticals and dietary supplements) has increased, particularly among the elderly, as it cannot be synthesized by the human body and plays a crucial role in several cellular physiological processes, including intestinal calcium and iron absorption, proteinogenesis, and fatty acid metabolism. However, the biochemical and immunological events that occur within the eukaryotic host-microbe-phage-nutrition interaction, especially when high amounts of lysine are consumed in nutraceutical or dietary supplement form by the elderly due to age-related requirements, as well as the impact on gut bacteria-derived metabolites, have not yet been fully studied. We hypothesized that (1) within an infectious-inflamed digestive milieu, the metabolism of excess extracellular lysine differs between young and senescent digestive cells, and (2) phages within the milieu exhibit alterations in host-microbe cometabolite signal profiles. To address this, we examined how gut microbes and phages, key regulators of eukaryotic host physiology, influence the immunometabolism of excess lysine. By combining two models of young and senescent digestive cells, the pathogenic P. aeruginosa PAO1, the Pseudomonas phage KPP22, and the anti-inflammatory bacterium Intestinimonas butyriciproducens, and simulating the pathogenesis of the interactive process of excessive lysine ingestion, we developed a five-way screening approach to explore key cell readouts, including viability, integrity, and function of the epithelial barrier, as well as cellular immunometabolic responses to exogenous lysine supplementation in cultures under infectious inflammation. Our findings are consistent with the possibility that host?microbe?microbe interactions involving lysine utilization and cross-feeding may influence the effects of lysine supplementation. These effects, whether beneficial or detrimental, can depend on the bacterial community, including the presence of pathogenic or potentially beneficial bacteria, interactions with intestinal phages, and the physiological conditions and metabolic requirements of the host and individual microbial taxa. en-copyright= kn-copyright= en-aut-name=GhadimiDarab en-aut-sei=Ghadimi en-aut-mei=Darab kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Bl?merSophia en-aut-sei=Bl?mer en-aut-mei=Sophia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KAYAAysel ?AH?N en-aut-sei=KAYA en-aut-mei=Aysel ?AH?N kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Kr?gerSandra en-aut-sei=Kr?ger en-aut-mei=Sandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=R?ckenChristoph en-aut-sei=R?cken en-aut-mei=Christoph kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Sch?ferHeiner en-aut-sei=Sch?fer en-aut-mei=Heiner kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=de HeerGeraldine en-aut-sei=de Heer en-aut-mei=Geraldine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=JarczakDominik en-aut-sei=Jarczak en-aut-mei=Dominik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuzakiShigenobu en-aut-sei=Matsuzaki en-aut-mei=Shigenobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BockelmannWilhelm en-aut-sei=Bockelmann en-aut-mei=Wilhelm kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Microbiology and Biotechnology, Max Rubner-Institut kn-affil= affil-num=2 en-affil=Faculty of Medicine, Christian-Albrechts-University of Kiel kn-affil= affil-num=3 en-affil=Department of Nutrition and Dietetics, Faculty of Health Sciences, Antalya Bilim University kn-affil= affil-num=4 en-affil=Institute of Pathology, Kiel University, University Hospital, Schleswig-Holstein kn-affil= affil-num=5 en-affil=Institute of Pathology, Kiel University, University Hospital, Schleswig-Holstein kn-affil= affil-num=6 en-affil=Laboratory of Molecular Gastroenterology & Hepatology, Christian-Albrechts-University & UKSH Campus Kiel kn-affil= affil-num=7 en-affil=University Center for Nutritional Medicine, University Medical Centre Hamburg-Eppendorf kn-affil= affil-num=8 en-affil=University Center for Nutritional Medicine, University Medical Centre Hamburg-Eppendorf kn-affil= affil-num=9 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Medical Laboratory Science, Faculty of Health Sciences, Kochi Gakuen University kn-affil= affil-num=11 en-affil=Department of Microbiology and Biotechnology, Max Rubner-Institut kn-affil= en-keyword=Inflammaging kn-keyword=Inflammaging en-keyword=Lysine kn-keyword=Lysine en-keyword=Host cells kn-keyword=Host cells en-keyword=Phages kn-keyword=Phages en-keyword=Syntrophy kn-keyword=Syntrophy en-keyword=Cell senescence kn-keyword=Cell senescence 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=20260913 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Significance of a Cell-Of-Origin-Based Classification in Pancreatic Ductal Adenocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with limited therapeutic options and poor clinical outcomes. Although PDAC has traditionally been thought to arise from ductal epithelial cells, recent studies using genetically engineered mouse models have demonstrated that acinar cells can also serve as a cell of origin, giving rise to tumors with distinct biological properties. Here, we investigated whether such lineage-specific differences are preserved in human PDAC. RNA sequencing was performed on resected specimens from 40 treatment-na?ve patients with PDAC, and tumors were classified into Acinar- and Ductal-subtypes using lineage-specific gene expression signatures derived from mouse models. This classification strategy was further applied to human PDAC cell lines, followed by in vitro drug sensitivity assays. Patients with Acinar-subtype tumors had significantly longer overall survival than those with Ductal-subtype tumors (median, 54.0 vs. 26.5?months; p? Methods: We retrospectively analyzed 225 nonagenarians undergoing surgical resection of CRC at 15 institutions between 2011 and 2022. Patients were stratified by GNRI-high/low status using two cutoffs: 98 (Cohort 1) and 86 (Cohort 2). Outcomes included postoperative complications, length of hospital stay, and overall survival (OS). Stabilized inverse-probability-of-treatment weighting (IPTW) was used to adjust for measured confounding.
Results: The median age was 92?years (female, 64.9%; colon cancer, 79.6%). GNRI-high patients had higher body mass index and albumin levels. Complication rates did not differ between the groups. After adjustment, GNRI-high patients in Cohort 1 had a shorter expected hospital stay (ratio 0.70, 95% CI 0.51?0.96; p?=?0.025) but no significant OS difference. In Cohort 2, GNRI-high patients had better OS (p? Conclusions: Preoperative GNRI was associated with hospital stay and OS in nonagenarians undergoing CRC surgery, although the OS association was significant only with the cohort-derived cutoff of 86, which requires external validation, and not with the literature-based cutoff of 98.

adults with growth hormone deficiency receiving weekly somapacitan or daily growth hormone: results from phase 3 REAL 1 trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Somapacitan is a long-acting growth hormone (GH) derivative approved for once-weekly treatment of adult GH deficiency (AGHD). This study aimed to evaluate the efficacy and safety of somapacitan and daily GH in Japanese individuals with AGHD.
Methods: This subgroup study included the 34-week main period of the multinational, randomized, parallel-group, phase 3 trial, REAL 1 (NCT02229851). Participants received once-weekly somapacitan or daily GH (Norditropin?), both administered subcutaneously. Investigators and trial sites were blinded. A total of 36 Japanese GH-na?ve individuals with AGHD were allocated to somapacitan or daily GH (excluding the placebo group of the global trial). Endpoints included change in truncal fat percentage to week 34 measured using dual-energy x-ray absorptiometry, as well as other body composition measures. Insulin-like growth factor I standard deviation score values were used for dose titration.
Results: In total, 36 Japanese individuals were included (18 and 18 in the somapacitan and daily GH group, respectively). 35 completed the main period (34 weeks). Mean (SD) change from baseline to week 34 in truncal fat percentage was -2.23 (2.50) %-points in the somapacitan group and -2.12 (4.21) %-points in the daily GH group. Other body composition measures also improved in both groups, including reduced visceral fat and increased lean body mass. Somapacitan was well tolerated, with a safety profile similar to daily GH.
Conclusions: In Japanese treatment-na?ve individuals with AGHD, once-weekly somapacitan demonstrated similar efficacy and safety to daily GH after 34 weeks of treatment. Somapacitan provides an effective alternative to daily GH in AGHD. en-copyright= kn-copyright= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RasmussenMichael H?jby en-aut-sei=Rasmussen en-aut-mei=Michael H?jby kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EndoTakaaki en-aut-sei=Endo en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Sv?rkeClaus en-aut-sei=Sv?rke en-aut-mei=Claus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaharaShigeyuki en-aut-sei=Tahara en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JohannssonGudmundur en-aut-sei=Johannsson en-aut-mei=Gudmundur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=Clinical Drug Development, Novo Nordisk A/S kn-affil= affil-num=3 en-affil=Medical Affairs Department, Novo Nordisk Pharma Ltd. kn-affil= affil-num=4 en-affil=Clinical Drug Development, Novo Nordisk A/S kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Nippon Medical School, Musashikosugi Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine and Clinical Nutrition, Institute of Medicine at Sahlgrenska Academy, University of Gothenburg and Department of Endocrinology, Diabetology, and Metabolism, Sahlgrenska University Hospital kn-affil= en-keyword=growth hormone kn-keyword=growth hormone en-keyword=adult growth hormone deficiency kn-keyword=adult growth hormone deficiency en-keyword=long-acting growth hormone kn-keyword=long-acting growth hormone en-keyword=somapacitan kn-keyword=somapacitan en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=94 cd-vols= no-issue=1 article-no= start-page=1 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An XAI-based meta-parameter tuning for time-series forecasting en-subtitle= kn-subtitle= en-abstract= kn-abstract=How can we efficiently determine meta-parameter values for deep learning-based time-series forecasting given a time-series dataset? This paper introduces Xtune, an efficient and novel meta-parameter tuning method for deep learning-based time-series forecasting, leveraging explainable AI techniques. In particular, this study focuses on optimizing the window size for time-series forecasting. Xtune determines the optimal meta-parameter value for these methods and can also be applied to tune the window size for anomaly detection methods that utilize deep learning-based time-series forecasting. Extensive experiments on real-world datasets and forecasting methods demonstrate that Xtune efficiently identifies the optimal meta-parameter value and consistently outperforms the existing methods in terms of execution speed. en-copyright= kn-copyright= en-aut-name=NakagawaHiroyuki en-aut-sei=Nakagawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SumitaShimon en-aut-sei=Sumita en-aut-mei=Shimon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IidaRyuichi en-aut-sei=Iida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuchiyaTatsuhiro en-aut-sei=Tsuchiya en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Osaka University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Osaka University kn-affil= en-keyword=Parameter optimization kn-keyword=Parameter optimization en-keyword=XAI kn-keyword=XAI en-keyword=Deep learning kn-keyword=Deep learning en-keyword=Time-series forecasting kn-keyword=Time-series forecasting en-keyword=Anomaly detection kn-keyword=Anomaly detection END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=30 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship Between Heated Tobacco Products and Placental Abruption: A Prospective Cohort Study Using Online Questionnaire en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Placental abruption (PA) is a critical obstetric complication, with maternal smoking recognized as a key risk factor. Despite the increased use of heated tobacco products (HTPs), the impact of HTPs remains unclear. This study investigated whether pregnant women using HTPs are at a higher risk of PA than non-users.
Methods: We analyzed data from “the Japan COVID-19 and Society Internet Survey,” a prospective, self-reported online survey cohort. Questionnaires were randomly distributed between July 28, 2021, and August 30, 2021. Pregnant respondents in 2021 were invited to complete an additional survey from February 14, 2022, to February 28, 2022. We set the outcome as the absolute risk difference (aRD) and relative risk ratio (rRR) of PA incidence due to smoking HTPs in the first trimester of pregnancy. The sample size included 12 836 participants. We calculated outcomes using a generalized linear model (GLM) and inverse probability of treatment weighting (IPTW). We also performed a Bayesian approach and multiple-bias analysis for sensitivity analysis.
Results: We found the robust aRD of 0.07 (95% confidence interval (CI): 0.06, 0.09) and the rRR of 11.3 (95% CI: 7.5, 17.0). Multiple bias analyses showed that unmeasurable confounders would need to have at least an rRR?=?14 relationship with both exposure and outcome to disprove the observed association. There has not been post hoc analysis or secondary use of data.
Conclusion: Early pregnancy use of HTPs is associated with an increased risk of PA. en-copyright= kn-copyright= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TabuchiTakahiro en-aut-sei=Tabuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Epidemiology, School of Public Health, Tohoku University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Placental abruption kn-keyword=Placental abruption en-keyword=Heated tobacco products kn-keyword=Heated tobacco products en-keyword=Pregnancy kn-keyword=Pregnancy en-keyword=Tobacco use kn-keyword=Tobacco use END start-ver=1.4 cd-journal=joma no-vol=980 cd-vols= no-issue=1 article-no= start-page=117 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Observing Supernova Neutrino Light Curves with Super-Kamiokande. V. Distance Estimation with Neutrinos en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neutrinos are pivotal signals in multimessenger observations of supernovae (SNe). Recent advancements in the analysis method of supernova (SN) neutrinos, especially in quantitative analysis, have significantly broadened scientific possibilities. This study demonstrates the feasibility of estimating distances to SNe using neutrinos. This estimation utilizes the direct relationship between the radius of a neutron star (NS) and the distance to the supernova, which is analogous to main-sequence fitting. The radius of an NS is determined with an approximate uncertainty of 10% through observations such as X-rays and gravitational waves. By integrating this information, the distance to the supernova can be estimated with an uncertainty of within 15% at a 95% confidence level. It has been established that neutrinos can pinpoint the direction of supernovae, and when combined with distance estimates, three-dimensional localization becomes achievable. This capability is vital for follow-up observations using multimessenger approaches. Moreover, more precise distance determinations to SNe through follow-up observations, such as optical observations, allow for accurate measurements of neutron-star radii. This data, via the neutron-star mass?radius relationship, could provide various insights into nuclear physics. en-copyright= kn-copyright= en-aut-name=SuwaYudai en-aut-sei=Suwa en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaAkira en-aut-sei=Harada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriMasamitsu en-aut-sei=Mori en-aut-mei=Masamitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakazatoKen’ichiro en-aut-sei=Nakazato en-aut-mei=Ken’ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkahoRyuichiro en-aut-sei=Akaho en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaMasayuki en-aut-sei=Harada en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanishiFumi en-aut-sei=Nakanishi en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SumiyoshiKohsuke en-aut-sei=Sumiyoshi en-aut-mei=Kohsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WendellRoger A. en-aut-sei=Wendell en-aut-mei=Roger A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Earth Science and Astronomy, The University of Tokyo kn-affil= affil-num=2 en-affil=Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS), RIKEN kn-affil= affil-num=3 en-affil=Division of Science, National Astronomical Observatory of Japan kn-affil= affil-num=4 en-affil=Faculty of Arts and Science, Kyushu University kn-affil= affil-num=5 en-affil=Faculty of Science and Engineering, Waseda University kn-affil= affil-num=6 en-affil=Department of Physics, Okayama University kn-affil= affil-num=7 en-affil=Department of Physics, Okayama University kn-affil= affil-num=8 en-affil=Department of Physics, Okayama University kn-affil= affil-num=9 en-affil=National Institute of Technology, Numazu College kn-affil= affil-num=10 en-affil=Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI), Todai Institutes for Advanced Study, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=6 article-no= start-page=775 end-page=785 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Single-Arm Phase 2 Study of Sotorasib Plus Carboplatin and Pemetrexed in Patients With Advanced Nonsquamous NSCLC With KRAS G12C Mutation (WJOG14821L, SCARLET) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The efficacy and safety of sotorasib plus platinum doublet chemotherapy in KRAS G12C-mutated nonsquamous NSCLC (nonsq NSCLC) have been previously reported with a limited follow-up period.
Methods: SCARLET is a single-arm phase 2 study involving chemotherapy-naive patients with KRAS G12C?mutated nonsq NSCLC. The participants received 960 mg daily plus four cycles of carboplatin (area under the curve = 5)/pemetrexed 500 mg/m2, followed by sotorasib/pemetrexed until disease progression. The primary end point was the overall response rate (ORR) and the secondary end points were progression-free survival (PFS), overall survival, and safety. Using plasma samples, next-generation sequencing was performed at baseline, 3 weeks, and during disease progression (the Japan Registry of Clinical Trials number 2051210086).
Results: Thirty patients were enrolled between October 2021 and July 2022 with a median follow-up of 14.8 months. ORR was 88.9% (80% confidence interval [CI]: 78.5%?94.8%, 95% CI: 70.8%?97.6%), median PFS was 6.6 months (95% CI: 5.3?16.7 mo), and median overall survival was 20.6 months (95% CI: 8.1 mo?not estimated). Among patients with programmed death-ligand 1 expression levels of 1% or higher and less than 1%, the ORRs were 82.3 and 100%, respectively, and the median PFS was 7.6 and 9.7 months, respectively. Using plasma samples, patients without KRAS G12C at baseline, without KRAS-related pathway co-alterations, or who cleared KRAS G12C at 3 weeks had better median PFS (16.7, 13.9, 8.7 mo, respectively). Tumor protein 53 mutations and EGFR and MET amplification were detected as acquired resistance.
Conclusions: In patients with KRAS G12C-mutated nonsq NSCLC, sotorasib plus carboplatin/pemetrexed reported favorable efficacy, particularly for patients with less than 1% programmed death-ligand 1, with manageable toxicity. en-copyright= kn-copyright= en-aut-name=AkamatsuHiroaki en-aut-sei=Akamatsu en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

subanalysis of the NINJA study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The clinical impact of hypomagnesemia induced by necitumumab plus gemcitabine and cisplatin (GCN) as a second-line or later therapy is unclear.
Objective: We aimed to evaluate the clinical characteristics and survival impact of hypomagnesemia induced by this therapy.
Design: This was a sub-analysis of the retrospective multicenter NINJA study.
Methods: Among the 93 patients enrolled in the NINJA study, this subanalysis included 75 patients with baseline serum magnesium concentrations.
Results: The incidence of grade ?2 hypomagnesemia was 18.0% in the patients with normal baseline serum magnesium concentrations and 42.8% in those with low concentrations (p?=?0.073). The discontinuation rates of GCN treatment owing to hypomagnesemia in each group were 0% and 7.1%, respectively (p?=?0.187). The number of necitumumab doses and severity of hypomagnesemia were positively correlated (r?=?0.389, p? Conclusion: GCN as a second-line or later therapy may be tolerable regardless of the patient’s baseline serum magnesium concentration. On the other hand, early serum magnesium reduction with this therapy is associated with a poor prognosis. However, caution should be needed because our results lacked sufficient information for confounding variables other than those analyzed here that may influence the correlation between hypomagnesemia and survival. en-copyright= kn-copyright= en-aut-name=TanzawaShigeru en-aut-sei=Tanzawa en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaHiroshige

Internet Cross-Sectional Survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=It is unclear whether patterns of alcohol consumption are associated with sleep disturbance. We aimed to investigate the relationship between comprehensive alcohol-related factors and insomnia symptoms, as well as sleep quality, among adult women in Japan. Responses to an online cross-sectional survey were gathered from 12,000 women. The survey items included demographic characteristics, alcohol consumption (Alcohol Use Disorders Identification Test, nightcaps, years of drinking), sleep-related factors (sleep duration, insomnia symptoms, sleep quality), lifestyle-related factors, and mental health. Binary logistic regression was used to investigate the relationship between alcohol consumption and both insomnia symptoms and sleep quality. A total of 10,233 women were included in the final analysis. The results revealed that several alcohol-related behaviors, including the consumption of nightcaps and years of drinking, were significantly associated with insomnia symptoms and poor sleep quality. Specifically, nightcaps were significantly associated with all types of insomnia symptoms and poor sleep quality, with a higher odds ratio than other alcohol-related items. Our findings suggest that specific alcohol-related behaviors, particularly the consumption of nightcaps, are associated with insomnia symptoms and poor sleep quality among women. Intervention programs for alcohol consumption should be provided to prevent sleep problems among women. en-copyright= kn-copyright= en-aut-name=NakajimaSuguru en-aut-sei=Nakajima en-aut-mei=Suguru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuichiro en-aut-sei=Otsuka en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KaneitaYoshitaka en-aut-sei=Kaneita en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItaniOsamu en-aut-sei=Itani en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuwabaraYuki en-aut-sei=Kuwabara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinjoAya en-aut-sei=Kinjo en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MinobeRuriko en-aut-sei=Minobe en-aut-mei=Ruriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaesatoHitoshi en-aut-sei=Maesato en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiguchiSusumu en-aut-sei=Higuchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YoshimotoHisashi en-aut-sei=Yoshimoto en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=JikeMaki en-aut-sei=Jike en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KasugaHideaki en-aut-sei=Kasuga en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=ItoTeruna en-aut-sei=Ito en-aut-mei=Teruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=OsakiYoneatsu en-aut-sei=Osaki en-aut-mei=Yoneatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=2 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=3 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=4 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=5 en-affil=Division of Environmental and Preventive Medicine, Department of Social Medicine, Faculty of Medicine, Tottori University kn-affil= affil-num=6 en-affil=Division of Environmental and Preventive Medicine, Department of Social Medicine, Faculty of Medicine, Tottori University kn-affil= affil-num=7 en-affil=National Hospital Organization Kurihama Medical and Addiction Center kn-affil= affil-num=8 en-affil=National Hospital Organization, Ryukyu Hospital kn-affil= affil-num=9 en-affil=National Hospital Organization Kurihama Medical and Addiction Center kn-affil= affil-num=10 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Family Medicine, General Practice and Community Health, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=12 en-affil=Department of Food Science and Nutrition, Faculty of Life and Environmental Science, Showa Women’s University kn-affil= affil-num=13 en-affil=Department of Hygiene and Preventive Medicine, Fukushima Medical University kn-affil= affil-num=14 en-affil=Department of Food and Nutrition, Koriyama Women’s University kn-affil= affil-num=15 en-affil=Division of Environmental and Preventive Medicine, Department of Social Medicine, Faculty of Medicine, Tottori University kn-affil= en-keyword=alcohol drinking kn-keyword=alcohol drinking en-keyword=female kn-keyword=female en-keyword=sleep duration kn-keyword=sleep duration en-keyword=sleep quality kn-keyword=sleep quality 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=17 cd-vols= no-issue= article-no= start-page=1 end-page=13 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=Skin disorder within 30?days is a favorable prognostic factor in patients with lung squamous cell carcinoma treated with necitumumab plus gemcitabine and cisplatin: a sub-analysis of the NINJA study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Skin disorders are major adverse events associated with necitumumab plus gemcitabine and cisplatin (Neci?+?GC) administration. However, the prognostic effect of skin disorders in patients with lung squamous cell carcinoma (LSCC) administered Neci?+?GC is unclear.
Objectives: We examined this prognostic effect in patients with LSCC, and the usefulness of minocycline administration.
Design: This was a sub-analysis of the retrospective multicenter NINJA study.
Methods: We performed a landmark survival analysis according to the presence of skin disorders at Day 30 of treatment and examined the usefulness of minocycline for treating skin disorders.
Results: Among the 93 patients, 62 (66.7%) had a skin disorder at Day 30. Nineteen, 30, and 13 patients experienced Grade 1, 2, and 3 skin disorders, respectively. The overall survival (OS) and progression-free survival (PFS) of patients with skin disorders at Day 30 were longer than those of patients without skin disorders (median OS: 434 vs 278?days, p?=?0.0201; median PFS: 148 vs 82?days, p?=?0.0835). Multivariable analysis showed that a skin disorder at Day 30 was an independent prognostic factor for both OS (p?=?0.0044) and PFS (p?=?0.0514). Of the 62 patients with skin disorders at Day 30, 38 (61.3%) were taking minocycline, and their time to treatment failure (TTF) was better than that in patients not taking minocycline (median TTF: 148 vs 101?days, p?=?0.0495).
Conclusion: A skin disorder within 30?days was a favorable prognostic factor for patients with LSCC administered Neci?+?GC. Additionally, minocycline administration may be beneficial in patients who develop skin disorders within 30?days. en-copyright= kn-copyright= en-aut-name=KinoshitaFumihiko en-aut-sei=Kinoshita

stability and domain‐specific structural features of tumor autoantigens regulate autoantibody epitope propensity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Autoantibodies against tumor-associated autoantigens are clinically valuable biomarkers for cancer diagnosis; however, the structural determinants governing epitope selectivity remain unknown. Here, we investigated whether the intrinsic conformational stability of target autoantigens regulates the epitope propensity of tumor-associated autoantibodies in non-small cell lung cancer. Using a dual-antigen Luminex bead-based assay that presents each autoantigen in both native and S-cationized denatured forms, we directly compared IgG autoantibody reactivity toward conformational and linear epitopes across 11 autoantigens. Intrinsically disordered aggregation-prone autoantigens, including cancer/testis antigens, NY-ESO-1, and XAGE-1b, predominantly elicit linear epitope-directed responses, whereas thermodynamically stable soluble autoantigens generally drive conformational epitope recognition. Intriguingly, for autoantigens harboring both ordered and disordered segments, the immune response is strictly guided by domain-specific biophysics: while p53-specific antibodies preferentially target their flanking disordered regions, the Wilms' tumor protein 1 exceptionally drives conformational recognition directed toward its structured zinc-finger domains. Recombinant solubility in Escherichia coli broadly correlated with epitope class across all 11 autoantigens, confirming that prokaryotic folding efficiency generally reflects intrinsic conformational stability in vivo for autonomously folding monomeric cytosolic proteins. Independent computational validation was provided by the concordance between the experimental solubility ratios and AlphaFold3-derived Rosetta energy unit/solvent-accessible surface area values, demonstrating the convergence of thermodynamic estimates and patient-derived immune data within a unifying biophysical framework. These findings establish that the autoantibody epitope propensity is closely associated with the thermodynamic stability of the target autoantigen and provide a rational basis for tailoring antigen preparation strategies for autoantibody-based cancer diagnosis. en-copyright= kn-copyright= en-aut-name=MiyamotoAi en-aut-sei=Miyamoto en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoRika en-aut-sei=Yamamoto en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaguchiRyui en-aut-sei=Sakaguchi en-aut-mei=Ryui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KutsumaRikako en-aut-sei=Kutsuma en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriTakeru en-aut-sei=Mori en-aut-mei=Takeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasuiMirei en-aut-sei=Masui en-aut-mei=Mirei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HonjoTomoko en-aut-sei=Honjo en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FutamiMidori en-aut-sei=Futami en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriiMariko en-aut-sei=Morii en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeHiromi en-aut-sei=Watanabe en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KuribayashiTadahiro en-aut-sei=Kuribayashi en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FutamiJunichiro en-aut-sei=Futami en-aut-mei=Junichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University 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=Department of Bioscience, Faculty of Life Science, Okayama University of Science kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=14 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=autoantibody kn-keyword=autoantibody en-keyword=biomarker kn-keyword=biomarker en-keyword=cancer/testis antigen kn-keyword=cancer/testis antigen en-keyword=epitope propensity kn-keyword=epitope propensity en-keyword=intrinsically disordered regions kn-keyword=intrinsically disordered regions en-keyword=protein engineering kn-keyword=protein engineering en-keyword=tumor-associated antigens kn-keyword=tumor-associated antigens END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=9 article-no= start-page=e70208 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=Proton‐Radiation‐Tolerant Silicon Photonic Charge Sensor for Spacecraft Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Silicon waveguides are promising platforms for spacecraft potential sensing owing to their compactness and immunity to electromagnetic interference. However, proton-induced optical absorption in operating silicon waveguides has not been quantitatively clarified, despite their direct exposure to the space radiation environment during spacecraft operation. Here, we present a systematic elucidation of proton-radiation effects on a photonic charge sensor based on silicon photonic crystal waveguides. During proton irradiation at 20 keV, we quantitatively evaluate the increase in optical absorption under device operation and find that a fluence of 1.0 ×1014 cm? 2 induces an additional absorption coefficient of approximately 0.41 cm? 1 . We further demonstrate that the sensor retains its ability to measure spacecraft potential even after exposure to a high proton fluence of 1.0 ×1015 cm? 2 , confirming its intrinsic radiation tolerance. These results establish the radiation robustness of silicon-waveguide- based sensing mechanisms and provide the first quantitative basis for implementing photonic charge sensors in radiation-rich spacecraft environments. en-copyright= kn-copyright= en-aut-name=TakahamaWataru en-aut-sei=Takahama en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaKosei en-aut-sei=Otsuka en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiharaAyumi en-aut-sei=Ishihara en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HojoRikuto en-aut-sei=Hojo en-aut-mei=Rikuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MogamiTomofumi en-aut-sei=Mogami en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiKohtaku en-aut-sei=Suzuki en-aut-mei=Kohtaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakahashiYasushi en-aut-sei=Takahashi en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Physics and Electronics, Osaka Metropolitan University kn-affil= affil-num=2 en-affil=Department of Physics and Electronics, Osaka Metropolitan University kn-affil= affil-num=3 en-affil=Department of Physics and Electronics, Osaka Metropolitan University kn-affil= affil-num=4 en-affil=Department of Space Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=5 en-affil=ElectrostaticEngineering DEPT, Kasuga Denki INC kn-affil= affil-num=6 en-affil=Department of Space Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=7 en-affil=Research and Development, The Wakasa Wan Energy Research Center kn-affil= affil-num=8 en-affil=Faculty of Environmental, Life, Natural Science and Technology,Okayama University kn-affil= en-keyword=photonic crystal waveguides kn-keyword=photonic crystal waveguides en-keyword=potential sensors kn-keyword=potential sensors en-keyword=radiation-tolerant sensors kn-keyword=radiation-tolerant sensors en-keyword=space silicon photonics kn-keyword=space silicon photonics en-keyword=spacecrafts charging kn-keyword=spacecrafts charging END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=26 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Incidence and survival outcomes of myocarditis and pericardial diseases associated with immune checkpoint inhibitor therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Immune checkpoint inhibitor(ICI) induced cardiac immune related adverse events are challenging to study; Leveraging large data bases like TriNetX global health network may provide needed insights.
Methods We performed a retrospective cohort study including patients diagnosed neoplasm and 18 and older when receiving ICI therapy from 1/1/2011 to 12/31/2022. Queried ICD 9/10 codes identified patients experiencing myocarditis, pericarditis, pericardial effusion, and cardiac tamponade within 1 year of ICI initiation. Survival analyses compared one-year overall survival (OS) of patients experiencing cardiac irAEs against propensity score matched populations not experiencing them.
Results In 88,928 identified ICI patients, the incidence of myocarditis(0.48%), pericarditis(0.22%), and cardiac tamponade(0.47%) were less than 1% while pericardial effusion occurred in 4.71% of patients. Hazard ratios (HRs) were significantly higher in all cardiac irAE groups: myocarditis (HR:1.26, 95% CI:1.04?1.54, p?=?0.02), pericarditis (HR:1.36, 95% CI:1.02?1.82, p?=?0.04), pericardial effusion (HR:1.49, 95% CI:1.39?1.59, p? Discussion/conclusion Utilizing a uniquely large cohort of ICI patients, this study further shows the rarity of cardiac inflammatory irAEs and highlights their significant impact on patient survival. en-copyright= kn-copyright= en-aut-name=OzakiAya F. en-aut-sei=Ozaki en-aut-mei=Aya F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SayerMichael en-aut-sei=Sayer en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagasakaMisako en-aut-sei=Nagasaka en-aut-mei=Misako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LeeBenjamin J. en-aut-sei=Lee en-aut-mei=Benjamin J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DohJean en-aut-sei=Doh en-aut-mei=Jean kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaqviAli en-aut-sei=Naqvi en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NowrouziNareh en-aut-sei=Nowrouzi en-aut-mei=Nareh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=PatelPranav M. en-aut-sei=Patel en-aut-mei=Pranav M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=School of Pharmacy & Pharmaceutical Sciences, University of California kn-affil= affil-num=2 en-affil=School of Pharmacy & Pharmaceutical Sciences, University of California kn-affil= affil-num=3 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Hematology and Oncology, University of California kn-affil= affil-num=5 en-affil=Department of Pharmacy, University of California kn-affil= affil-num=6 en-affil=Department of Pharmacy, University of California kn-affil= affil-num=7 en-affil=Division of Cardiology, Department of Medicine, University of California kn-affil= affil-num=8 en-affil=School of Pharmacy & Pharmaceutical Sciences, University of California kn-affil= affil-num=9 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Division of Cardiology, Department of Medicine, University of California kn-affil= en-keyword=Immune checkpoint inhibitors kn-keyword=Immune checkpoint inhibitors en-keyword=Myocarditis kn-keyword=Myocarditis en-keyword=Cardiotoxicity kn-keyword=Cardiotoxicity en-keyword=Immune-related adverse events kn-keyword=Immune-related adverse events en-keyword=Overall survival kn-keyword=Overall survival END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=1 article-no= start-page=251 end-page=261 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=2005 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of Phospholane 1-Oxide Having Oxygen Functional Groups from a 4-Bromobutylphoshinate Derivative en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ethyl 4-bromo-2,3-dimethoxybutyl(phenyl)phosphinate (10a) was prepared from 2,3-di-O-methyl-L-threitol (12) in five steps.

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.

However, the relationship between lumen water content and hydraulic connectivity has rarely been examined directly at the cellular level. In this study, we combined cryo-scanning electron microscopy and fluorescence microscopy to compare lumen water status with hydraulic connectivity on the same xylem surface in current-year xylem of Carpinus tschonoskii and Aria alnifolia, using tension-driven dye uptake to identify conductive vessels. Most vessels were stained and water-filled, consistent with functional conduits, whereas unstained gas-filled vessels corresponded to embolized conduits. Notably, certain vessels retained water despite lacking dye signals, indicating hydraulic isolation from the conductive xylem network. Although these vessels represented a minor fraction of the conduit population, their occurrence suggests that the traditionally binary classification should be expanded to incorporate an additional conduit function. These vessels were observed in both species, suggesting that hydraulically disconnected vessels represent a common phenomenon across species. These findings reveal previously underrecognized heterogeneity in xylem hydraulic organisation and demonstrate that conduit status cannot always be inferred from the presence of water alone. Recognising this intermediate condition refines current interpretations of xylem function and highlights the value of integrating high-resolution imaging with hydraulic measurements. en-copyright= kn-copyright= en-aut-name=OgasaMayumi?Y. en-aut-sei=Ogasa en-aut-mei=Mayumi?Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UtsumiYasuhiro en-aut-sei=Utsumi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YazakiKenichi en-aut-sei=Yazaki en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiNaoko?H. en-aut-sei=Miki en-aut-mei=Naoko?H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukudaKenji en-aut-sei=Fukuda en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Kansai Research Center, Forestry and Forest Products Research Institute kn-affil= affil-num=2 en-affil=Ashoro Research Forest, Kyushu University kn-affil= affil-num=3 en-affil=Hokkaido Research Center, Forestry and Forest Products Research Institute kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology kn-affil= affil-num=5 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= en-keyword= cryo-scanning electron microscopy kn-keyword= cryo-scanning electron microscopy en-keyword=fluorescence microscopy kn-keyword=fluorescence microscopy en-keyword=hydraulic isolation kn-keyword=hydraulic isolation en-keyword=vessel function kn-keyword=vessel function en-keyword=water distribution kn-keyword=water distribution END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=3 article-no= start-page=1 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250903 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Presentation Quality Assessment through Audience 3D Facial and Head Direction Using Conventional Cameras en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper shows the method for evaluating the quality of presentations using information from the audience's facial and head behavior. Existing studies have focused on assessing presentation skills by analyzing presentation materials and the presenter's verbal and non-verbal cues, however, since a presentation is an interaction between the presenter and the audience, the presentation quality is not only influenced by presenter's information but also audience's information such as their background knowledge. This means that the presenter's output alone is not enough for a comprehensive evaluation of the presentation. To address this, we show a method that utilizes videos of the audience recorded during presentations using two cameras: one capturing from the presenter's point of view and the other from around the presentation screen. The 3D position and direction of the audience's face were detected using face detection techniques, which were then used to predict gaze targets, such as the presenter and the presentation screen. The number of times these targets were looked at during the presentation served as feature values for evaluating presentation quality. Using a dataset of 18 presenters and 32 audience members, this paper shows a significant correlation between subjective ratings and behavioral characteristics. It also demonstrates an algorithm that infers the quality of a presentation from these feature values. en-copyright= kn-copyright= en-aut-name=ImamuraGoshi en-aut-sei=Imamura en-aut-mei=Goshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakazawaAtsushi en-aut-sei=Nakazawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= en-keyword=presentation quality kn-keyword=presentation quality en-keyword=computer vision kn-keyword=computer vision en-keyword=gaze kn-keyword=gaze END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=15 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=MIT/TFE family transcription factors, Mitf and Tfec, redundantly promote pigment cell differentiation and retinal epithelium pigmentation in teleosts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Transcription factors of the MIT/TFE family?mitfa, mitfb, and tfec?play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages. We previously reported that the combined loss of mitfa and mitfb leads to a complete absence of melanophores, xanthophores, and leucophores in medaka.
Results: Here, we describe newly generated hypomorphic alleles of mitfa and mitfb, which result in delayed melanophore development. Using these hypomorphic mutants in combination with a newly generated null allele of tfec, we show that Tfec can partially compensate for the loss of Mitfa and Mitfb in melanophore, xanthophore, and leucophore differentiation. Consistent with previous findings in zebrafish, loss of tfec alone results in the complete absence of iridophores. Importantly, simultaneous null mutations in all three genes cause a complete loss of all four chromatophore types and lead to defective pigmentation of the retinal pigmented epithelium (RPE), which is not derived from the neural crest in both Oryzias species and in zebrafish. Using an RPE-specific marker, we further show that the RPE is specified and structurally intact but fails to melanize.
Conclusions: These findings indicate that the redundant functions of Mitfa, Mitfb, and Tfec are not only essential for the specification of diverse pigment cell types but also critical for RPE pigmentation. en-copyright= kn-copyright= en-aut-name=ListerJames en-aut-sei=Lister en-aut-mei=James kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiwakaKeisuke en-aut-sei=Sugiwaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraTetsuaki en-aut-sei=Kimura en-aut-mei=Tetsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaRieko en-aut-sei=Tanaka en-aut-mei=Rieko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GodaMakoto en-aut-sei=Goda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiHikaru en-aut-sei=Kobayashi en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoueChikako en-aut-sei=Inoue en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MasengiKawilarang W.

Severe influenza and excess mortality in this population remain major public health concerns, underscoring the need for novel treatment strategies.
Methods and analysis This multicentre, investigator-initiated, randomised, double-blind clinical trial evaluated the efficacy and safety of the investigational drug favipiravir injection (T-705IV) in combination with oseltamivir phosphate, compared with oseltamivir monotherapy in hospitalised patients with influenza aged ?65 years. Both T-705IV and oseltamivir phosphate will be administered for 5?days. The primary endpoint is time from randomisation to recovery within 15 days. Recovery is defined as either actual hospital discharge or sustained clinical status permitting discharge for 3 consecutive days. Clinical status will be assessed using a 7-point ordinal scale based on hospitalisation status and oxygen requirement. The primary analysis employs a Bayesian Cox proportional hazards model with a non-informative prior to estimate the posterior probability that the HR exceeds 1.0. The secondary endpoints include the distribution of 7-point scale scores over a 29-day period; rates of clinical worsening at days 15 and 29; duration of fever; all-cause mortality; intensive care unit admission within 29 days; pneumonia complication rate at 15 days; and changes in viral titre and viral RNA load on days 1, 2, 3 and 7. Safety will be assessed through the collection of adverse events (AEs) up to day 29. Pharmacokinetic evaluation will include measurement of plasma favipiravir concentrations on day 3. The planned sample size is 80 patients (40 per group).

kn-abstract=The rise of antibiotic resistance in Staphylococcus aureus is a major threat to global health. Resistance often emerges when bacteria acquire foreign DNA elements, such as the SCCmec cassette that makes strains resistant to nearly all β-lactam antibiotics. Yet, not all S. aureus lineages take up these elements equally, raising the question of what prevents some strains from becoming drug-resistant. Here we identify a previously unknown defence factor that explains this mystery in a common skin lineage (ST188), frequently isolated from patients with atopic dermatitis. Such defence factor is encoded by a gene, which we name sadR, that is present in methicillin-susceptible ST188 strains but absent from resistant counterparts. SadR exhibits RNase activity that provides anti-bacteriophage and anti-plasmid defence, thus acting as a barrier to the uptake of mobile genetic elements. Gene sadR is found in methicillin-susceptible strains in S. aureus lineages other than ST188, and is consistently located adjacent to rlmH, the canonical SCCmec integration site. Moreover, SadR homologues are widespread across staphylococci and other bacteria suggesting a previously unrecognised family of RNase-based defence systems. en-copyright= kn-copyright=

en-abstract= kn-abstract=The vibrations caused by external factors (such as fluids) or internal factors often pose strength-related problems in mechanical and structural components. Although several studies have investigated the material fatigue characteristics during vibration, reports on complex vibration modes such as torsion bending are limited. In this study, we addressed this gap by conducting experiments and finite element analyses on I- and L-shaped aluminum alloy specimens under bending and torsion bending vibrations, respectively. We established a reliable method to estimate the strain at the notch by utilizing the strain measured at a position outside the notch and a ratio derived from finite element analysis. This method allows for accurate assessment of the critical strain history without interfering with crack observation. Using the strain range at the crack initiation site effectively unified the fatigue life evaluation for both specimens. en-copyright= kn-copyright= en-aut-name=SakamotoJunji en-aut-sei=Sakamoto en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TadaNaoya en-aut-sei=Tada en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UemoriTakeshi en-aut-sei=Uemori en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=bending vibration kn-keyword=bending vibration en-keyword=crack propagation kn-keyword=crack propagation en-keyword=damage-equivalent strain kn-keyword=damage-equivalent strain en-keyword=resonance frequency reduction kn-keyword=resonance frequency reduction en-keyword=torsion bending vibration kn-keyword=torsion bending vibration en-keyword=vibration fatigue kn-keyword=vibration fatigue END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=2 article-no= start-page=143 end-page=150 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Variation in the Association between Frailty and Disability over 10 Years: A Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although frailty is associated with disability, its long-term persistence and changes over time remain unclear. This study aimed to investigate the long-term association between frailty and the incidence of disability over a 10-year follow-up period, evaluating how this association changed over time. Methods: This cohort study was conducted in Okayama City, Japan. Community-dwelling older adults aged ?65 years were included. Frailty was assessed using the Kihon Checklist, and disability was defined as a new certification for long-term care insurance. The association between frailty and disability was examined across five time periods (years 1?2, 3?4, 5?6, 7?8, and 9?10) using a marginal structural model with inverse probability of treatment weighting and inverse probability of censoring weighting. Results: The final analysis included 45,291 participants, with 17.3% classified as frail. The adjusted odds ratios (ORs) for the association between frailty and the incidence of disability gradually decreased over time but remained throughout the 10-year follow-up period. The adjusted ORs and 95% confidence intervals were 2.90 (2.55?3.29) for years 1?2, 2.40 (2.09?2.75) for years 3?4, 2.03 (1.76?2.34) for years 5?6, 1.75 (1.52?2.01) for years 7?8, and 1.58 (1.38?1.82) for years 9?10. Conclusion: Frailty was consistently associated with the incidence of disability over a 10-year follow-up period, with a stronger association in the earlier years and a gradual decline over time. en-copyright= kn-copyright= en-aut-name=HagiyamaAkikazu en-aut-sei=Hagiyama en-aut-mei=Akikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Frailty kn-keyword=Frailty en-keyword=Persons with disabilities kn-keyword=Persons with disabilities en-keyword=Aged kn-keyword=Aged en-keyword=Longitudinal studies kn-keyword=Longitudinal studies END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=3 article-no= start-page=ofaf118 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Amikacin Liposome Inhalation Suspension and Amikacin Resistance Development in Patients With Refractory Mycobacterium avium Complex Pulmonary Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Amikacin liposome inhalation suspension (ALIS) is key for treating refractory Mycobacterium avium complex pulmonary disease (MAC-PD). However, microbiological efficacy by subtype remains unknown. The frequency and mechanism of amikacin (AMK) resistance during ALIS administration are also unclear.
Methods. We retrospectively analyzed data from refractory MAC-PD patients who received ALIS for at least 6 months as an adjunct to guideline-based therapy at the NHO Kinki Chuo Chest Medical Center. We investigated the efficacy of ALIS and analyzed gene expression and the frequency of AMK resistance.
Results. We enrolled 44 patients (median age, 72.0 years): 19 (43.2%) with the noncavitary nodular bronchiectatic (NC-NB) subtype and 25 (56.8%) with the cavitary subtype. Overall, sputum culture conversion was 56.8% (25/44): 84.2% (16/19) in the NC-NB subtype and 36.0% (9/25) in the cavitary subtype (P = .001). During intermittent dosing, conversion occurred in 50.0% (9/18). In patients with C-reactive protein (CRP) ?1?mg/dL, cavitary subtype, and clarithromycin (CLM) resistance, the risk ratio for persistently positive cultures was 10.81 (95% CI, 1.66?70.40) compared with those with CRP <1?mg/dL, NC-NB subtype, and CLM susceptibility. Of all participants, 15.9% (7/44) had isolates with AMK resistance (minimum inhibitory concentration ?128??g/mL), and of these 71.4% (5/7) had rrs mutations.
Conclusions. Regimens that included ALIS achieved higher culture conversion in NC-NB than cavitary MAC-PD cases. High CRP levels, cavitary disease, and CLM resistance predicted persistent culture positivity. AMK resistance acquired during ALIS administration may limit treatment options for refractory MAC-PD. en-copyright= kn-copyright= en-aut-name=KuraharaYu en-aut-sei=Kurahara en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaShiomi en-aut-sei=Yoshida en-aut-mei=Shiomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsugiAsami en-aut-sei=Osugi en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaYuya en-aut-sei=Tanaka en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiTakehiko en-aut-sei=Kobayashi en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KawasakiYohei en-aut-sei=Kawasaki en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MitaraiSatoshi en-aut-sei=Mitarai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsuyuguchiKazunari en-aut-sei=Tsuyuguchi en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Internal Medicine, NHO Kinki Chuo Chest Medical Center kn-affil= affil-num=2 en-affil=Clinical Research Center, NHO Kinki Chuo Chest Medical Center , Osaka , kn-affil= affil-num=3 en-affil=Department of Mycobacterium Reference and Research, Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=4 en-affil=Department of Internal Medicine, NHO Kinki Chuo Chest Medical Center kn-affil= affil-num=5 en-affil=Clinical Research Center, NHO Kinki Chuo Chest Medical Center kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Biostatistics, Graduate School of Medicine, Saitama Medical University kn-affil= affil-num=8 en-affil=Department of Mycobacterium Reference and Research, Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=9 en-affil=Department of Internal Medicine, NHO Kinki Chuo Chest Medical Center kn-affil= en-keyword=amikacin liposome inhalation suspension kn-keyword=amikacin liposome inhalation suspension en-keyword=Mycobacterium avium complex kn-keyword=Mycobacterium avium complex en-keyword=noncavitary-nodular bronchiectatic kn-keyword=noncavitary-nodular bronchiectatic en-keyword=amikacin resistance kn-keyword=amikacin resistance en-keyword=rrs mutation kn-keyword=rrs mutation END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=60 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260920 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Carbon solubility and liquid?liquid immiscibility in Fe?C?S ternary system up to 6?GPa: implications for the core of small planetary bodies en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-pressure, high-temperature experiments were conducted in a multi-anvil press using seven different starting compositions to investigate the phase relations of Fe?C?S liquids at pressures up to 6 GPa and temperatures up to 2000 K. Quenched samples revealed immiscible C-rich and S-rich metallic liquids at 2 and 4 GPa, manifesting as either large immiscible zones or emulsified smaller droplets. On the contrary, no immiscibility was observed at 5 or 6 GPa. At these higher pressures, the carbon solubility limit, significantly reduced by increasing sulfur content in the ternary liquid, prevents the formation of a liquid phase rich in both C and S. Our findings thus indicate that super-liquidus immiscibility in Fe-rich compositions does not occur at pressures above 5 GPa, due to the differential pressure dependence of C solubility and miscibility. The limited C solubility in S-rich liquids at higher pressures effectively suppresses immiscibility. Based on these results, terrestrial planetary bodies with fluid cores at pressures exceeding 5 GPa are unlikely to experience liquid?liquid immiscibility, even when both carbon and sulfur are abundant, as sulfur limits carbon solubility and promotes its exsolution. For the Moon, immiscibility-induced core stratification is not expected, though local emulsification could occur near the core?mantle boundary (CMB). In smaller bodies, a two-liquid Fe?C?S core may form at high temperatures, but progressive cooling may lead to graphite crystallization and the potential development of a graphitic crust. en-copyright= kn-copyright= en-aut-name=ZhaoBin en-aut-sei=Zhao en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorardGuillaume en-aut-sei=Morard en-aut-mei=Guillaume kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ManthilakeGeeth en-aut-sei=Manthilake en-aut-mei=Geeth kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ParisiadesParaskevas en-aut-sei=Parisiades en-aut-mei=Paraskevas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangJing en-aut-sei=Yang en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FeiYingwei en-aut-sei=Fei en-aut-mei=Yingwei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Le GodecYann en-aut-sei=Le Godec en-aut-mei=Yann kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoNozomi en-aut-sei=Kondo en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=AntonangeliDaniele en-aut-sei=Antonangeli en-aut-mei=Daniele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=UMR CNRS 7590, Institut de Min?ralogie, de Physique des Mat?riaux et de Cosmochimie, IMPMC, Mus?um National d’Histoire Naturelle, Sorbonne Universit? kn-affil= affil-num=3 en-affil=Laboratoire Magmas et Volcans, Universit?

Unlike planar polycyclic aromatic hydrocarbons that suffer from aggregation-caused quenching (ACQ), the twisted molecular architecture of TNps effectively inhibits π-π stacking interactions. Consequently, several TNps exhibit crystallization-induced emission enhancement (CIEE) or retain high quantum yields (up to 0.94) in the solid state. Kinetic analysis revealed that this efficiency stems from the significant suppression of non-radiative rates (knr) due to the restricted intramolecular rotation in the rigid crystal lattice. Furthermore, a decisive topological effect on the radiative rate (kf) was demonstrated. The 1,4-, 1,5- and 2,6-linked isomers display allowed transitions with large oscillator strengths (f) and fast radiative rate (kf = ca. 5 × 108 s?1), whereas the 2,7-linked isomers exhibit forbidden-like character with prolonged lifetimes. A distinct linear correlation between the experimental and calculated values empirically supports the applicability of the Strickler-Berg relationship in both solution and solid states. These findings demonstrate that controlling the chromophore connectivity is a powerful strategy to tune excited-state dynamics for developing high-performance deep-blue organic emitters. en-copyright= kn-copyright= en-aut-name=YamajiMinoru en-aut-sei=Yamaji en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiKengo en-aut-sei=Suzuki en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoHideki en-aut-sei=Okamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Division of Molecular Science, Graduate School of Science and Engineering, Gunma University kn-affil= affil-num=2 en-affil=Hamamatsu Photonics K.K. kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Environment, Life, Natural Sciences and Technology, Okayama University kn-affil= en-keyword=Deep-blue fluorescence kn-keyword=Deep-blue fluorescence en-keyword=Solid-state emission kn-keyword=Solid-state emission en-keyword=Multi-chromophore system kn-keyword=Multi-chromophore system en-keyword=Radiative rate kn-keyword=Radiative rate en-keyword=Density functional theory (DFT) kn-keyword=Density functional theory (DFT) en-keyword=Structure-property relationship kn-keyword=Structure-property relationship END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue= article-no= start-page=485 end-page=494 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhancement of mechanical properties in a cast hypereutectic Al?Si alloy via rapid cooling in heated mold continuous casting en-subtitle= kn-subtitle= en-abstract= kn-abstract=To enhance mechanical properties in cast hypereutectic Al?Si alloys, Al?14.5Si samples were produced by the heated mold continuous casting (HMC). The HMC process was conducted under unidirectional solidification at cooling rates (CRs) ranging from 4.6 × 10?1 to 1.3 × 103 K/s, which were obtained by controlling the casting speed (CS). The microstructure basically consisted of α-Al dendrite, Al?Si eutectic and primary Si, while their area fractions (fα-Al, fe, and fp-Si) varied depending on the CR. At the low CR of 4.6 × 10?1 K/s, their area fractions were as follows: fα-Al = 0.2%, fe = 97.3%, and fp-Si = 2.5%, which is the typical microstructural morphology of a hypereutectic Al-Si alloy. In contrast, at the high CR of 1.3 × 103 K/s, those area fractions were altered to fα-Al = 32.3% and fe = 67.7%, while primary Si was strongly suppressed (fp-Si ? 0%) despite the hypereutectic Al?14.5Si alloy. Moreover, at the high CR, the aluminum matrix appears to exhibit a nearly uniform crystal orientation along <101>. These microstructural changes may be related not only to high CR but also the difference in growth kinetics between primary Si and α-Al dendrites. Accordingly, an apparent eutectic composition shifted from 12.6 to 19.7 wt% Si. The atypical microstructural formation led to a significant improvement in the tensile properties: the ultimate tensile strength of 400 MPa and fracture strain of 17%. These tensile properties are more than twice those of the conventional cast hypereutectic Al?14.5Si alloy. en-copyright= kn-copyright= en-aut-name=TakeuchiShuhei en-aut-sei=Takeuchi en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaShota en-aut-sei=Nakagawa en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShinzatoYoshifumi en-aut-sei=Shinzato en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MinodaTadashi en-aut-sei=Minoda en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhtsukaNaotaka en-aut-sei=Ohtsuka en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=UACJ Corporation kn-affil= affil-num=3 en-affil=UACJ Corporation kn-affil= affil-num=4 en-affil=UACJ Corporation kn-affil= affil-num=5 en-affil=UACJ Corporation kn-affil= affil-num=6 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= en-keyword=Hypereutectic Al?Si alloy kn-keyword=Hypereutectic Al?Si alloy en-keyword=Heated mold continuous casting kn-keyword=Heated mold continuous casting en-keyword=Mechanical property kn-keyword=Mechanical property en-keyword=Microstructural characteristics kn-keyword=Microstructural characteristics en-keyword=Supercooling kn-keyword=Supercooling END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=100037 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=Older patients with LBCL show comparable outcomes to younger patients and product-specific profiles in CAR-T therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anti-CD19 chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a key treatment option for patients with relapsed or refractory large B-cell lymphoma (LBCL). However, data on its effectiveness and safety in older populations remain limited, particularly in real-world clinical practice. Moreover, comparative outcomes among different CAR-T products across age groups have not yet been fully characterized. We conducted a nationwide retrospective cohort study using data from the Japanese Society for Transplantation and Cellular Therapy. A total of 908 patients who received CAR-T therapy between January 2019 and September 2024 were included. Patients were categorized as younger (aged <65 years) or older (aged ?65 years). Subgroup analyses were performed by CAR-T product (tisagenlecleucel [tisa-cel], lisocabtagene maraleucel [liso-cel], and axicabtagene ciloleucel [axi-cel]). In univariate analysis, 1-year overall survival (OS) and progression-free survival (PFS) were comparable between younger and older patients (OS, 69.4% vs 65.7% [P = .40]; PFS, 47.9% vs 54.1% [P = .17]). In multivariate analysis, age ?65 years showed no significant association with OS (hazard ratio, 0.88; 95% confidence interval, 0.65-1.21; P = .44). The incidence of immune effector cell?associated neurotoxicity syndrome was significantly higher in older patients (12.7% vs 7.0%; P = .005). Compared with tisa-cel, axi-cel and liso-cel were associated with superior PFS, predominantly in younger patients. Among older patients, axi-cel was associated with higher nonrelapse mortality rate than tisa-cel. CAR-T therapy is feasible and effective for older patients with LBCL. These findings support age-adapted treatment strategies that consider both the efficacy and toxicity of each product. en-copyright= kn-copyright= en-aut-name=ShibataSho en-aut-sei=Shibata

kn-title=Structural and functional analysis of a photosystem II mutant PsbA3-S264V en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) catalyzes water oxidation and oxygen evolution by a light-induced electron transfer chain, leading to the generation of electrons, protons and dioxygen. D1-S264 is a residue located close to the QB-binding site, and mutation of this residue has been shown to bring significant effects on the electron transfer and oxygen-evolving activities. Here we analyzed the structure of a Thermosynechococcus elongatus mutant PsbA3-S264V by cryo-electron microscopy at 1.96 ? resolution, which showed significant changes in the structure surrounding the bicarbonate and QB-binding region. Due to change of Ser to Val, the hydrogen-bond between the QB carbonyl oxygen and S264 is altered, which changed the protonation pathway of QB from the original route of D1-H252 through D1-S264 to QB, to a new, longer and less efficient route of D1-H252 through D1-F265 to QB. Two residues, D1-E244 and D2-E242, changed their side chain orientations significantly. Among them, D2-E242 adopted two conformations, and both are largely deviated from the original structure. All these changes led to alterations in hydrogen-bonding networks of two channels, channel A and channel B, that connect the stromal surface to QB and may function to transport protons to protonate QB. Furthermore, isothermal titration calorimetry experiments showed a diminished 3-(3,4-dichlorophenyl)-1, 1-dimethylurea (DCMU) binding affinity of the mutated PSII, which may be explained by a structural rotation of D1-F255 in the mutant based on structural analysis of DCMU-bound PSII. These findings offer valuable insights into the functions of D1-S264 in QB protonation and function, as well as in the DCMU-binding. en-copyright= kn-copyright= en-aut-name=FanSongbo en-aut-sei=Fan en-aut-mei=Songbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangHaowei en-aut-sei=Jiang en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsaiPi-Cheng en-aut-sei=Tsai en-aut-mei=Pi-Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JiaAnqi en-aut-sei=Jia en-aut-mei=Anqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugiuraMiwa en-aut-sei=Sugiura en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Proteo-Science Research Center, Ehime University kn-affil= affil-num=8 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=PsbA3-S264V kn-keyword=PsbA3-S264V en-keyword=QB protonation kn-keyword=QB protonation en-keyword=DCMU-binding kn-keyword=DCMU-binding en-keyword=Thermosynechococcus elongatus kn-keyword=Thermosynechococcus elongatus END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=e70330 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=Transcystostomal Bladder Tumor Resection in a Transgender Man After Phalloplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Phalloplasty in transgender men is frequently complicated by a neourethral stricture, precluding standard transurethral access for bladder tumor resection. We describe the first reported case of a transcystostomal bladder tumor resection in a transgender man after a radial forearm free flap (RFFF) phalloplasty.
Materials and Surgical Technique
A 65-year-old transgender man, 23?years after an RFFF phalloplasty, presented with gross hematuria and a 15-mm posterior bladder tumor. A 7.95?Fr flexible ureteroscope reached the bladder but with markedly limited maneuverability. A two-stage transcystostomal approach was used: a 14?Fr suprapubic cystostomy (SPC) was placed 1?month before resection for tract maturation, followed by balloon dilation and insertion of a 24?Fr resectoscope. The modified Valdivia position enabled simultaneous transcystostomal and transurethral access with gravity-assisted irrigation drainage. Complete tumor resection was achieved without complications, and pathology confirmed noninvasive papillary urothelial carcinoma (pTa, low-grade) with negative margins. A single immediate intravesical instillation of pirarubicin was administered. Surveillance cystoscopy via the cystostomy tract at 3 and 6?months revealed no recurrence; the patient continues to void while standing with the cystostomy catheter capped.
Discussion
The two-stage transcystostomal approach, combining prior SPC placement, balloon tract dilation, and the modified Valdivia position, enabled safe oncological control while preserving phallic anatomy and standing voiding function. This technique offers a reproducible option for bladder tumor resection in patients with functionally inadequate transurethral access after phalloplasty. en-copyright= kn-copyright= en-aut-name=MoriwakeTakatoshi en-aut-sei=Moriwake en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzakiNariaki en-aut-sei=Ozaki en-aut-mei=Nariaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoYuko en-aut-sei=Matsumoto en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiTomoko en-aut-sei=Kobayashi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsuboiIchiro en-aut-sei=Tsuboi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshinagaKasumi en-aut-sei=Yoshinaga en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamanoiTomoaki en-aut-sei=Yamanoi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawadaTatsushi en-aut-sei=Kawada en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NambaYuzaburo en-aut-sei=Namba en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Miyakekai Good Life Hospital kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Gender Center, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bladder neoplasms kn-keyword=bladder neoplasms en-keyword=gender-affirming surgery kn-keyword=gender-affirming surgery en-keyword=phalloplasty kn-keyword=phalloplasty en-keyword=suprapubic cystostomy kn-keyword=suprapubic cystostomy en-keyword=transgender persons kn-keyword=transgender persons 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．

Perioperative anaphylaxis caused by anesthetic agents or skin antiseptics poses a significant challenge to surgical management. We report a case of stoma-site single-incision laparoscopic Hartmann’s reversal (HR) performed in a patient with severe perioperative allergies.
CASE PRESENTATION: A 73-year-old woman underwent an emergency open Hartmann’s procedure with partial cystectomy for perforated sigmoid colon cancer with bladder invasion. After adjuvant chemotherapy, she developed a progressively enlarging giant parastomal hernia that significantly impaired daily activities. Two attempts at HR were aborted because of perioperative anaphylactic shock. Subsequent allergy evaluations suggested rocuronium and chlorhexidine as causative agents, and povidone-iodine was also avoided based on clinical history. Approximately 14 months after the initial surgery, single-incision laparoscopic HR using the stoma site was successfully performed under general anesthesia without neuromuscular blocking agents. Preoperative skin antisepsis was performed using benzalkonium chloride, avoiding both chlorhexidine and povidone-iodine. No additional abdominal incisions were required. The operative time was 2 h 56 min, with minimal blood loss. The postoperative course was uneventful and she was discharged on POD 9.
CONCLUSIONS: Stoma-site single-incision laparoscopic HR may represent a useful surgical option for selected patients with severe perioperative allergies to anesthetic agents and skin antiseptics, in whom minimizing abdominal approach and wound-related risks is particularly important. en-copyright= kn-copyright= en-aut-name=YanagiharaTsubasa en-aut-sei=Yanagihara en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaYusuke en-aut-sei=Yoshida en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShigeyasuKunitoshi en-aut-sei=Shigeyasu en-aut-mei=Kunitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoYoshitaka en-aut-sei=Kondo en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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, Okayama, Okayama, Japan kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Hartmann’s reversal kn-keyword=Hartmann’s reversal en-keyword=single-incision laparoscopic surgery kn-keyword=single-incision laparoscopic surgery en-keyword=parastomal hernia kn-keyword=parastomal hernia en-keyword=perioperative anaphylaxis kn-keyword=perioperative anaphylaxis en-keyword=chlorhexidine allergy kn-keyword=chlorhexidine allergy END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page=1926696 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=Phenotypic Characterization of Porphyromonas gulae Fimbria Mutants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Porphyromonas gulae has been established as a pathogen in animal periodontal disease and expresses several virulence factors, including fimbriae, lipopolysaccharide, and proteases. 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=12 cd-vols= no-issue=1 article-no= start-page=cr.26-0502 end-page= 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=Successful Lung Transplantation after Plasma Exchange in a Patient with High Thermal Amplitude Cold Agglutinins: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=INTRODUCTION: Cold agglutinins (CAs) are immunoglobulin M autoantibodies that induce red blood cell agglutination at low temperatures and may cause hemolytic or thrombotic complications during procedures associated with hypothermia. In lung transplantation (LT), blood may be exposed to low temperatures within the reperfused lung graft and the extracorporeal circulation circuit, potentially increasing the risk of CA-mediated complications. However, the perioperative significance of CAs in this setting remains unclear, and optimal management has not been established. We report a case of successful bilateral LT in a patient with high-thermal-amplitude CAs managed with preoperative plasma exchange (PLEX) and strict intraoperative temperature control.
CASE PRESENTATION: A 55-year-old man with diffuse panbronchiolitis and secondary pulmonary hypertension was listed for bilateral LT. Preoperative testing incidentally revealed clinically significant CAs, with a titer of 1:128 at 4°C and a thermal amplitude of 30°C. Because intraoperative blood temperature might approach this threshold despite active warming, a single preoperative session of PLEX using 36 units of fresh frozen plasma was performed to reduce the risk of a CA-mediated complication. Bilateral LT was subsequently completed under meticulous temperature management, including extracorporeal circulation maintained at 37.5°C, continuous systematic warming, avoidance of topical ice application, and rewarming of the donor lungs before reperfusion. After surgery, the CA titer decreased to 1:32. The postoperative course was uneventful, without thromboembolic events, primary graft dysfunction, or bronchial complications.
CONCLUSIONS: LT may be performed safely in selected patients with high-thermal-amplitude CAs when careful perioperative temperature control is combined with preoperative PLEX. PLEX should be considered when the anticipated intraoperative temperature is expected to approach the patient’s thermal amplitude threshold. en-copyright= kn-copyright= en-aut-name=MiyoshiYuya en-aut-sei=Miyoshi en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsanoNaomi en-aut-sei=Asano en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoHaruchika en-aut-sei=Yamamoto en-aut-mei=Haruchika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkaharaShuji en-aut-sei=Okahara en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery, Okayama University Hospital, Okayama, Okayama, Japan kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=cold agglutinins kn-keyword=cold agglutinins en-keyword=thermal amplitude kn-keyword=thermal amplitude en-keyword= lung transplantation kn-keyword= lung transplantation en-keyword=plasma exchange kn-keyword=plasma exchange en-keyword=extracorporeal circulation kn-keyword=extracorporeal circulation en-keyword=perioperative management kn-keyword=perioperative management END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue= article-no= start-page=112872 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prediction of tool-path and cycle time errors of CNC machining using a transformer-based deep learning model en-subtitle= kn-subtitle= en-abstract= kn-abstract=The prediction of tool-path and cycle time errors of computer numerical control (CNC) machining is important in manufacturing field. In this study, these errors are considered as sequential data corresponding to the lines of G-code, i.e., the error prediction is a sequence-to-sequence task, and a Transformer-based deep learning model was constructed to predict the tool-path and cycle time errors simultaneously, taking the positional increments and feed rate as the input. The training datasets were created by running a randomly generated G-code on a real CNC machine tool and subsequently tracking the actual errors, where the motion and feed rate are stochastically defined. The model is validated by conducting the error prediction on six sets of G-code. In addition, the comparison with a Bi-LSTM-based deep learning model is conducted. The results show that the prediction accuracy of the Transformer model can achieve the mean prediction accuracies of ±1 μm and ±1 ms in tool-path and cycle time error predictions, respectively. Furthermore, the Transformer model has a smaller prediction uncertainty than the Bi-LSTM model. Compared with conventional methods only analyzing tool-path errors or cycle-time errors, the utilized model has an advantage in its ability to simultaneously predict tool-path errors and cycle time errors. en-copyright= kn-copyright= en-aut-name=KanekoKazuki en-aut-sei=Kaneko en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiZongze en-aut-sei=Li en-aut-mei=Zongze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Tech, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= en-keyword=CNC machining kn-keyword=CNC machining en-keyword=Tool-path error kn-keyword=Tool-path error en-keyword=Cycle time error kn-keyword=Cycle time error en-keyword=Deep learning kn-keyword=Deep learning en-keyword=Transformer kn-keyword=Transformer END start-ver=1.4 cd-journal=joma no-vol=757 cd-vols= no-issue= article-no= start-page=125992 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=Multi-criteria evaluation of graphene oxide nanofiltration membranes for decaffeination en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nanofiltration (NF) offers a promising low-energy approach for producing decaffeinated instant coffee, while requires membranes that balance caffeine removal, water permeance, and retention of key coffee matrix compounds. Here, graphene oxide membranes (GOMs) were modified by sodium alginate (SA) intercalation, Ca2+ crosslinking, and their combined strategy to tune nanochannel structure and separation performance. The results show that membrane modification does not follow a simple monotonic trend; instead, small structural and chemical changes generate competing effects on permeance and selectivity through coupled transport, adsorption, and confinement mechanisms. To identify the most suitable membrane, a multi-criteria evaluation framework (MCEF) combining entropy weighting and TOPSIS was established using five key performance indicators: caffeine removal, flavour-related marker retention index, choline retention, water permeance, and concentration increase. This framework identified CGSM-1 as the best-performing flat membrane, which also showed promising performance in hollow-fibre form. In coffee filtration tests, CGSM-1 reduced caffeine concentration from 24.64 to 12.95?μg/mg, corresponding to a 47.4% reduction, while retaining measurable levels of HMF, trigonelline, NMP, and choline. These findings demonstrate the potential of engineered GOMs for selective caffeine reduction in coffee liquor and provide a practical evaluation strategy for membrane-based decaffeination. en-copyright= kn-copyright= en-aut-name=TianYihan en-aut-sei=Tian en-aut-mei=Yihan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LinTongxi en-aut-sei=Lin en-aut-mei=Tongxi 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=RenXiaojun en-aut-sei=Ren en-aut-mei=Xiaojun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JoshiRakesh en-aut-sei=Joshi en-aut-mei=Rakesh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=School of Materials Science and Engineering, University of New South Wales kn-affil= affil-num=2 en-affil=School of Materials Science and Engineering, University of New South Wales kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=School of Materials Science and Engineering, University of New South Wales kn-affil= affil-num=5 en-affil=School of Materials Science and Engineering, University of New South Wales kn-affil= en-keyword=Multi-criteria evaluation kn-keyword=Multi-criteria evaluation en-keyword=Decaffeination kn-keyword=Decaffeination en-keyword=Graphene oxide kn-keyword=Graphene oxide END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=3 article-no= start-page=e0910 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hepatocellular carcinoma in Fontan-associated liver disease: Incidence, risk stratification, and surveillance implications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Hepatocellular carcinoma (HCC) is a serious complication of Fontan-associated liver disease (FALD). However, data on its incidence, risk factors, and outcomes in this rare population are limited. We aimed to assess the incidence and predictors of HCC and evaluate the utility of surveillance in patients with FALD.
Methods: We conducted a retrospective cohort study on patients with FALD who were referred to our gastroenterology department. The cumulative incidence of HCC after FALD diagnosis was calculated, and multivariate analysis was used to identify independent risk factors. Overall survival after FALD diagnosis was compared between patients who developed HCC and those who did not.
Results: A total of 120 patients with FALD were followed up for a median period of 50.0 months. The cumulative incidence rates of HCC at 1, 2, and 3 years after FALD diagnosis were 0.9%, 2.7%, and 3.9%, respectively. Elevated alpha-fetoprotein (AFP) at FALD diagnosis was independently associated with HCC development (hazard ratio, 1.29; 95% confidence interval, 1.04?1.60; p=0.01). There was no significant difference in overall survival between patients with and without HCC in this cohort (log-rank test, p=0.50).
Conclusions: Patients with FALD face a non-negligible risk of developing HCC, thus supporting the need for surveillance. Elevated AFP levels at the time of FALD diagnosis may aid in risk stratification, which enables the targeted monitoring and early detection of HCC. Furthermore, routine surveillance contributes to the excellent prognosis of patients with FALD who develop HCC, thus making their prognosis comparable to that of patients without HCC. en-copyright= kn-copyright= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BabaKenji en-aut-sei=Baba en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Medical Development Field, Okayama University, Okayama, Japan kn-affil= affil-num=3 en-affil=Department of Pediatric Cardiology, Academic Fields of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Academic Fields of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Academic Fields of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Academic Fields of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=alpha-fetoprotein kn-keyword=alpha-fetoprotein en-keyword=FALD kn-keyword=FALD en-keyword=Fontan procedure kn-keyword=Fontan procedure en-keyword=retrospective cohort study kn-keyword=retrospective cohort study en-keyword=risk stratification kn-keyword=risk stratification END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=3 article-no= start-page=e044756 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long‐Term Outcomes and Risk Factors for Mortality After Single Ventricle Palliation for Asplenia Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: This study evaluated the long‐term outcomes of asplenia syndrome with single ventricle palliation, hypothesizing that total anomalous pulmonary vein connection (TAPVC), pulmonary atresia (PA), and greater than or equal to moderate atrioventricular valve regurgitation increase mortality risk.
Methods: This retrospective review analyzed 151 patients with asplenia syndrome who underwent single ventricle palliation between 1990 and 2024. The primary end point was mortality, with risk factors assessed by Cox regression analysis over a mean follow‐up of 9.3?years.
Results: The median age at initial operation was 35?days, including 70 neonates (46%). Overall, 62 (41%) patients died, whereas 66 (44%) patients are alive post‐Fontan completion. Survival probabilities at 1 and 20?years were 75.7% (95% CI, 67.9?81.8) and 53.7% (95% CI, 44.5?62.0), respectively. TAPVC (P=0.014), PA (P=0.007), and greater than or equal to moderate atrioventricular valve regurgitation (P=0.040) emerged as independent risk factors for mortality in the overall cohort. In the TAPVC cohort, independent risk factors for mortality included PA (P=0.019), infracardiac TAPVC (P=0.045), and neonatal TAPVC repair (P=0.018). When stratified by the risk factors of TAPVC, PA, or greater than or equal to moderate atrioventricular valve regurgitation, survival probabilities did not differ between patients with none or 1 of these conditions (P=0.181) but were significantly lower in those with ?2 risk factors (P<0.001, at 15?years: 0, 72.9%; 1, 59.1%; ?2, 32.8%).
Conclusions: Survival after single ventricle palliation for asplenia syndrome remains suboptimal, particularly when TAPVC, PA, and greater than or equal to moderate atrioventricular valve regurgitation are present in combination rather than in isolation. Improved strategies or surgical techniques are required for this complex asplenia syndrome cohort. en-copyright= kn-copyright= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SanoShunji en-aut-sei=Sano en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokudaYuhei en-aut-sei=Tokuda en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraAyari en-aut-sei=Kimura en-aut-mei=Ayari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=StaffaSteven J. en-aut-sei=Staffa en-aut-mei=Steven J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZurakowskiDavid en-aut-sei=Zurakowski en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatric Cardiac Surgery Showa Medical University Toyosu Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology, Critical Care and Pain Medicine, Boston Children’s Hospital, Boston Harvard Medical School kn-affil= affil-num=6 en-affil=Department of Anesthesiology, Critical Care and Pain Medicine, Boston Children’s Hospital, Boston Harvard Medical School kn-affil= affil-num=7 en-affil=Department of Cardiovascular Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=asplenia syndrome kn-keyword=asplenia syndrome en-keyword=atrioventricular valve regurgitation kn-keyword=atrioventricular valve regurgitation en-keyword=heterotaxy kn-keyword=heterotaxy en-keyword=pulmonary atresia kn-keyword=pulmonary atresia en-keyword=total anomalous pulmonary vein kn-keyword=total anomalous pulmonary vein END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=e70160 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=Clinical and Microbiological Characteristics of Invasive Group A Streptococcus Infection: Four Case Series of Re‐Emerging Pathogens en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Group A Streptococcus (GAS), particularly the M1UK lineage, has re-emerged as a major global public health concern following the COVID-19 pandemic, with a rise in invasive GAS (iGAS) and streptococcal toxic shock syndrome (STSS). Although STSS is under national surveillance in Japan, comprehensive molecular monitoring of iGAS infections remains limited, and the clinical characteristics of M1UK-associated iGAS have not been fully elucidated.
Methods: We retrospectively reviewed four consecutive iGAS cases requiring intensive care between March and May 2024. Detailed clinical, microbiological, and genomic investigations were performed to characterize the causative strains and their associated virulence profiles.
Results: All patients required respiratory and/or circulatory support with surgical debridement. Three cases involved necrotizing fasciitis, and one involved intra-abdominal infection secondary to ovarian tumor rupture. All four patients received penicillin G and clindamycin as definitive antimicrobial therapy, with two developing severe drug-related adverse events. Genotypic analysis identified three isolates as emm1 strains, including two M1UK lineage strains. The two M1UK isolates commonly harbored multiple superantigen genes. All isolates remained susceptible to β-lactam, clindamycin, and macrolide antibiotics.
Conclusion: This case series documents the identification of the M1UK lineage among critically ill patients with iGAS infections in Japan. Our findings support the need for continued molecular surveillance while reinforcing the importance of prompt surgical source control and appropriate antimicrobial therapy in the management of severe iGAS. en-copyright= kn-copyright= en-aut-name=OkaharaShuji en-aut-sei=Okahara en-aut-mei=Shuji 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=HamaguchiYuto en-aut-sei=Hamaguchi en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HishiikeMasanobu en-aut-sei=Hishiike en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MotoiYohei en-aut-sei=Motoi en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Department of Intensive Care, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=emm type kn-keyword=emm type en-keyword=Group A Streptococcus kn-keyword=Group A Streptococcus en-keyword=M1UK strain kn-keyword=M1UK strain en-keyword=necrotizing fasciitis kn-keyword=necrotizing fasciitis en-keyword=Streptococcus pyogenes kn-keyword=Streptococcus pyogenes END start-ver=1.4 cd-journal=joma no-vol=2006 cd-vols= no-issue=13 article-no= start-page=2075 end-page=2078 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=200608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Preparation of a 2′-O-Acetyl-1′-O-(4-methoxybenzyl)-l-biopterin Derivative, a Versatile Precursor for a Selective Synthesis of l-Biopterin Glycosides en-subtitle= kn-subtitle= en-abstract= kn-abstract=l-Rhamnose was converted, over a 13-step-sequence, into 2′-O-acetyl-N 2-(N,N-dimethylaminomethylene)-1′-O-(4-methoxybenzyl)-3-[2-(4-nitrophenyl)ethyl]-l-biopterin, an appropriately protected precursor of 1′-O- and 2′-O-monoglycosyl-l-biopterin.

Samples returned from the asteroid Ryugu are uncontaminated and contain organic matter. Such samples enable an investigation of the processes that formed and altered extraterrestrial organic matter. Here, the FTIR and Raman responses of insoluble organic matter (IOM) isolated from Ryugu particles and carbonaceous chondrites are reported. Several relationships were observed: (1) a strong positive correlation of CH2/CH3 plotted against aliphatics/C=C; (2) a strong negative correlation of CH2/CH3 plotted against δ15N and δ13C; and (3) strong negative correlations of FTIR band ratios plotted against Raman band parameters and D/G values. The data are not consistent with even moderate heating of the IOM, as indicated by CH2/CH3 ratios that are consistent with unheated carbonaceous chondrites. The C and N isotope data previously collected for each Ryugu particle preclude aqueous alteration based on our understanding of its effects on carbonaceous chondrite IOM. Mixing of several IOM endmembers was considered, but due to the similarities of the particle with the lowest CH2/CH3 ratio to the other particles in terms of its other spectroscopic parameters, this scenario was considered unlikely. Finally, the effects of irradiation were considered, and UV irradiation, in particular, was hypothesised to be the best explanation for the trends observed. Overall, the data highlight the importance of comprehensive data sets for revealing extraterrestrial processes, which could define the nature of organic matter reaching habitable environments, such as those of the Early Earth. en-copyright= kn-copyright= en-aut-name=PotiszilChristian en-aut-sei=Potiszil en-aut-mei=Christian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaMasahiro en-aut-sei=Yamanaka en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtaTsutomu en-aut-sei=Ota en-aut-mei=Tsutomu 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=TanakaRyoji en-aut-sei=Tanaka en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunihiroTak en-aut-sei=Kunihiro en-aut-mei=Tak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=5 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=6 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=7 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=8 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=9 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=26394 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cold SiO2-rich slabs reaching the CMB revealed by the seifertite phase boundary en-subtitle= kn-subtitle= en-abstract= kn-abstract=A cold silica (SiO2)-rich subducted slab creates notable heterogeneity above the core-mantle boundary (CMB), influencing the evolution of the Earth’s mantle. This slab may exhibit characteristic anomalies in the longitudinal and shear wave seismic velocity above the CMB, attributed to the SiO2 phase transition into its dense polymorph, seifertite. However, the transition depth remains unclear due to the often-observed metastable phases in experiments. To address this long-standing challenge, we conducted laser-heated diamond anvil cell experiments with synchronised rapid X-ray diffraction measurements alongside theoretical calculations. The slope of the seifertite phase boundary was less steep than previously estimated, and consequently, the temperature profile of the slab crosses the boundary twice, like the post-perovskite transition. We observed a decrease in shear wave velocity beneath Hawaii and Central America, and we found anti-correlation in seismic wave velocities matching the depth range of the seifertite transition in a cold slab beneath Central America. This may provide evidence that a cold SiO2-rich slab descends towards the CMB. en-copyright= kn-copyright= en-aut-name=SinmyoRyosuke en-aut-sei=Sinmyo en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Kawaguchi-ImadaSaori en-aut-sei=Kawaguchi-Imada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoRei en-aut-sei=Sato en-aut-mei=Rei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsuruKeisuke en-aut-sei=Otsuru en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaiKenji en-aut-sei=Kawai en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakumaHiroshi en-aut-sei=Sakuma en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SueharaShigeru en-aut-sei=Suehara en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaitaniShuhou en-aut-sei=Maitani en-aut-mei=Shuhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Physics, School of Science and Technology, Meiji University kn-affil= affil-num=2 en-affil=Japan Synchrotron Radiation Research Institute kn-affil= affil-num=3 en-affil=Department of Earth and Planetary Science, School of Science, The University of Tokyo kn-affil= affil-num=4 en-affil=Japan Synchrotron Radiation Research Institute kn-affil= affil-num=5 en-affil=Japan Synchrotron Radiation Research Institute kn-affil= affil-num=6 en-affil=Environmental Circulation Composite Materials Group, National Institute for Materials Science kn-affil= affil-num=7 en-affil=Environmental Circulation Composite Materials Group, National Institute for Materials Science kn-affil= affil-num=8 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=9 en-affil=Department of Physics, School of Science and Technology, Meiji University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=5 article-no= start-page=1093 end-page=1101 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Breast ultrasound screening in young adult women undergoing infertility treatment at an infertility clinic: a retrospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Young adult women are increasingly undergoing infertility treatment; however, evidence regarding breast cancer screening in this population remains limited. Given that most women in this age group have dense breast tissue, for which mammography has limited sensitivity, breast ultrasound (US) is often used as a screening modality. A diagnosis of breast cancer during infertility treatment may affect both oncologic management and reproductive planning. This study aimed to examine the clinical relevance of breast US in women in their 30s undergoing infertility treatment at an infertility clinic.
Methods We retrospectively analyzed 1,336 women aged 30?39 years who underwent screening breast US between November 1, 2018, and June 30, 2025. Analyses were performed on a per-woman basis, including only the first screening examination for each participant. Breast composition was categorized according to the BI-RADS 5th edition Atlas. Screening outcomes?including recall rate, positive predictive value (PPV), cancer detection rate, and US findings (mass and non-mass findings)?were assessed using medical records. The continuation of infertility treatment, defined as ongoing or resumed treatment during the diagnostic evaluation period, was descriptively evaluated as part of the clinical context.
Results Of the 1,336 women, 1,277 (95.6%) were classified as having dense breasts. A total of 140 (10.5%) women were recalled for further evaluation. In these recalled cases, 147 findings were identified, comprising 113 mass lesions (76.8%) and 34 non-mass findings (23.1%). Four breast cancers were identified, corresponding to a cancer detection rate of 0.30% and a PPV of 2.86%. Histological diagnoses included one mucinous carcinoma, two invasive carcinomas of no special type (NST), and one ductal carcinoma in situ (DCIS). Following diagnostic evaluation, 124 recalled women (88.6%) continued infertility treatment.
Conclusions Breast US screening in women in their 30s undergoing infertility treatment provides descriptive findings within a specific clinical setting. The observed cancer detection rate appears to be within the range reported in previous studies; however, direct comparisons are limited due to differences in study populations and clinical contexts. The clinical course following recall was described as part of the screening pathway. Further prospective and multicenter studies are required to clarify the clinical significance of breast US screening in this population. en-copyright= kn-copyright= en-aut-name=NakanoKanako

spectroscopy supported by DFT calculations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tungsten (W) is mobile in magmatic?hydrothermal and deep subduction zone fluids, and its stable isotopes offer potential as tracers of fluid-rock interactions. We investigated W behavior in aqueous fluids using in-situ Raman spectroscopy on slightly acidic to alkaline Na2WO4 solutions (10?3?10?1 M W) and WO3?H2O/D2O ± NaCl systems up to 1.4 GPa and ?800 °C, with the band assignments supported by density functional theory (DFT) calculations. Raman spectra showed that the ν1 mode of WO42? persisted to the highest P?T conditions in alkaline fluids, while additional high-frequency bands near 950 or 973 cm?1 appeared at elevated T in the studied fluids. Their relative intensities depended on T, pH, and NaCl content; the 973 cm?1 band was only observed above 650 °C in Na-free fluids. Substitution of H2O with D2O did not significantly affect the band frequencies. Based on analogous molybdenum experiments, previous in-situ studies, and thermodynamic models, these high-T bands are assigned to mononuclear species rather than polynuclear species, consistent with the stepwise formation of hydrogentungstate anion, HWO4?, and then neutral tungstic acid, H2WO4, as T increases. DFT vibrational frequency calculations for HWO4?, H2WO4, and their D-substituted species support this interpretation, suggesting tetrahedral HWO4? and higher-coordinated H2WO4 as plausible species. The present study clarifies Raman band assignments for HWO4? and paratungstate A (W7O246?) to address previous ambiguities in the literature, and confirms that polynuclear species play a negligible role in high-T ore-forming fluids. The tetrahedral HWO4? appears to be a predominant transport species in NaCl-bearing metamorphic fluids and may govern stable W isotope fractionation during deep fluid-rock interactions. en-copyright= kn-copyright= en-aut-name=TakahashiNaoko en-aut-sei=Takahashi en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraMichihiko en-aut-sei=Nakamura en-aut-mei=Michihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KagiHiroyuki en-aut-sei=Kagi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Earth Science, Graduate School of Science, Tohoku University kn-affil= affil-num=2 en-affil=Department of Earth Science, Graduate School of Science, Tohoku University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Geochemical Research Center, Graduate School of Science, The University of Tokyo kn-affil= en-keyword=Tungsten kn-keyword=Tungsten en-keyword=Aqueous speciation kn-keyword=Aqueous speciation en-keyword=Hydrothermal fluids kn-keyword=Hydrothermal fluids en-keyword=Subduction zone kn-keyword=Subduction zone en-keyword=Diamond anvil cell kn-keyword=Diamond anvil cell en-keyword=Raman spectroscopy kn-keyword=Raman spectroscopy en-keyword=DFT calculations kn-keyword=DFT calculations END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=1 article-no= start-page=104678 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2027 dt-pub=202701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of correcting beam hardening and detector response function in photon-counting X-ray imaging when using anti-coincidence mode en-subtitle= kn-subtitle= en-abstract= kn-abstract=X-ray imaging using photon-counting detectors (PCDs) allows for the calculation of quantitative images such as the effective atomic number (?eff). However, physical phenomena such as characteristic X-ray emission and charge sharing can cause incomplete total absorption events during signal generation, which reduces the accuracy of X-ray penetration analysis. To solve the problem, an anti-coincidence mode (ACM) has been developed, but complete correction has not been established. We aimed to investigate the accuracy of ?eff image when the proposed software-based corrections, namely beam hardening and response function corrections, are added to the hardware-based correction of the ACM. The response function was calculated using the Monte-Carlo simulation code. In a simulation study, we analyzed a phantom composed of virtual materials with ?eff values of 4?16. While sufficient accuracy cannot be achieved by applying only the ACM, it was demonstrated that low-noise ?eff images can be obtained by applying our correction. Furthermore, it was demonstrated that ?eff images of food samples can be generated by using actual non-destructive testing equipment with a 10?m/min transportation speed. In conclusion, our correction procedure can maximize the performance of PCDs, and our findings are essential for promoting imaging techniques concerning quantitative images. en-copyright= kn-copyright= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishigamiRina en-aut-sei=Nishigami en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiDaiki en-aut-sei=Kobayashi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KasueTakuya en-aut-sei=Kasue en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=2 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=3 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=4 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=5 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= en-keyword=X-ray non-destructive testing kn-keyword=X-ray non-destructive testing en-keyword=Photon-counting detector kn-keyword=Photon-counting detector en-keyword=Coincidence summing kn-keyword=Coincidence summing en-keyword=CdTe detector kn-keyword=CdTe detector en-keyword=X-ray imaging kn-keyword=X-ray imaging END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=8291 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Water exchange process and bulk composition regulate slab dynamics and deep earthquakes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Water strongly influences deep mantle processes, including geochemical cycles, slab dynamics, and deep-focus earthquakes. Yet the stability and interactions of hydrous minerals with nominally anhydrous minerals (NAMs) under the water-undersaturated conditions of subducting slabs remain unclear. Here we show, using high-pressure and high-temperature experiments on MgO?SiO2?H2O systems (~2?wt% H2O), that hydrous minerals progressively dehydrate in the mantle transition zone, transferring water to NAMs such as wadsleyite and ringwoodite, while the cold slab core stays nearly dry. Rapid dehydration near the top of the lower mantle may generate fluids linked to the deepest earthquakes. Our results indicate that dry olivine transformations, rather than dehydration embrittlement, likely trigger most deep-focus earthquakes, and that hydration variations in NAMs influence slab deformation and stagnation above 660?km. The bulk Mg/Si ratio controls hydrous mineral stability, suggesting harzburgite transports water more efficiently than peridotite. en-copyright= kn-copyright= en-aut-name=ZhuJintao en-aut-sei=Zhu en-aut-mei=Jintao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaoRenbiao en-aut-sei=Tao en-aut-mei=Renbiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhangLifei en-aut-sei=Zhang en-aut-mei=Lifei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Center for High Pressure Science and Technology Advanced Research (HPSTAR) kn-affil= affil-num=3 en-affil=SKLab-DeepMinE, MOEKLab-OBCE, School of Earth and Space Sciences, Peking University kn-affil= affil-num=4 en-affil=Institute for Planetary Materials, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=44 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260622 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a preoperative accuracy prediction model using machine learning for implant placement in static-guided surgery: retrospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This study aimed to develop a machine learning model capable of preoperatively predicting three-dimensional implant placement errors at the implant apex in static-guided surgery and to identify the clinical features associated with placement accuracy.
Methods Clinical data partially derived from a previous observational study were analyzed. In total, 181 patients and 480 implants placed using fully static-guided surgery were included in this study. The outcome variable was defined as three-dimensional implant placement error at the implant apex relative to the preoperative simulation, dichotomized as less than 0.5 mm or ??0.5 mm. Twenty-one clinical and radiographic factors previously suggested to influence the placement accuracy were used as explanatory variables. The feature importance was evaluated using three gradient boosting decision tree models. Furthermore, a stacking model combining multiple classifiers was constructed, and the classification performance was assessed using ten-fold cross-validation.
Results The feature importance analysis identified 12 features associated with implant placement errors. The stacking model demonstrated superior classification performance compared to individual classifiers. The true positive rate was 0.73, false negative rate was 0.27, false positive rate was 0.14, and true negative rate was 0.86.
Conclusions The proposed stacking model correctly classified 86% of cases with implant placement error less than 0.5 mm and 73% of cases with implant placement error of ??0.5 mm. These findings suggest that the proposed model may support the preoperative evaluation of implant placement accuracy in static-guided surgeries. en-copyright= kn-copyright= en-aut-name=MinoTakuya en-aut-sei=Mino en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuokaYurina en-aut-sei=Matsuoka en-aut-mei=Yurina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorookaKen’ichi en-aut-sei=Morooka en-aut-mei=Ken’ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokumotoKana en-aut-sei=Tokumoto en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimizuHiroaki en-aut-sei=Shimizu en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KurosakiYoko en-aut-sei=Kurosaki en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Kimura-OnoAya en-aut-sei=Kimura-Ono en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KishimotoHiromitsu en-aut-sei=Kishimoto en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=MaekawaKenji en-aut-sei=Maekawa en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Removable Prosthodontics and Occlusion, School of Dentistry, Osaka Dental University kn-affil= affil-num=2 en-affil=Department of Semiconductor, Computer Science and Applied Mathematics, Graduate School of Science and Technology, Kumamoto University kn-affil= affil-num=3 en-affil=Division of Biomedical Engineering, Faculty of Advanced Science and Technology, Kumamoto University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, School of Medicine, Hyogo Medical University kn-affil= affil-num=5 en-affil=Shimizu Dental Clinic kn-affil= affil-num=6 en-affil=Department of Removable Prosthodontics and Occlusion, School of Dentistry, Osaka Dental University kn-affil= affil-num=7 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, School of Medicine, Hyogo Medical University kn-affil= affil-num=9 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Removable Prosthodontics and Occlusion, School of Dentistry, Osaka Dental University kn-affil= en-keyword=Implant placement kn-keyword=Implant placement en-keyword=Accuracy kn-keyword=Accuracy en-keyword=Surgical guide kn-keyword=Surgical guide en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Prediction algorithms kn-keyword=Prediction algorithms en-keyword=Decision trees kn-keyword=Decision trees en-keyword=Support vector machine kn-keyword=Support vector machine en-keyword=Sensitivity and specificity kn-keyword=Sensitivity and specificity END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=9 article-no= start-page=1890 end-page=1900 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Event-free survival and recurrence patterns after curative resection for locally advanced head and neck squamous cell carcinoma: single-institution real-world outcomes prior to the introduction of perioperative immunotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Perioperative immune checkpoint inhibitors have improved outcomes for resectable locally advanced head and neck squamous cell carcinoma (HNSCC). However, real-world surgical outcome data based on contemporary endpoints remain limited.
Methods We retrospectively analyzed 233 patients who underwent curative-intent surgery for locally advanced HNSCC. Event-free survival (EFS) and overall survival (OS) were evaluated. Unresectable recurrence-free survival (URFS) was explored as an additional endpoint to capture post-recurrence treatment feasibility. Prognostic factors were assessed using Cox proportional hazards models.
Results The median follow-up duration was 18.2 months. The 1-year EFS and OS rates were 67.1% and 89.4%, respectively. pN2 or higher disease, venous invasion, and perineural invasion were identified as independent adverse prognostic factors. Recurrence occurred in 34.8% of patients; among these, disease control at the last follow-up was achieved in 61.7% following curative-intent salvage treatment. Salvage surgery was associated with significantly improved post-recurrence survival (p? Conclusions This study provides real-world surgical outcome data for resectable locally advanced HNSCC prior to the introduction of perioperative immunotherapy. Recurrence remains a major clinical challenge, with heterogeneous post-recurrence outcomes influenced by treatment feasibility. These findings may help inform interpretation of treatment outcomes and clinical decision-making in the evolving era of perioperative immunotherapy. en-copyright= kn-copyright= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaoiYuto en-aut-sei=Naoi en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaGo en-aut-sei=Hasegawa en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamasakiTakuto en-aut-sei=Yamasaki en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NodaHiroki en-aut-sei=Noda en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoShohei en-aut-sei=Fujimoto en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoJunya en-aut-sei=Matsumoto en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Head and neck squamous cell carcinoma kn-keyword=Head and neck squamous cell carcinoma en-keyword=Surgery kn-keyword=Surgery en-keyword=Event-free survival kn-keyword=Event-free survival en-keyword=Recurrence kn-keyword=Recurrence en-keyword=Salvage surgery kn-keyword=Salvage surgery 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=20 cd-vols= no-issue=3 article-no= start-page=e70101 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260826 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Critical role of cellular communication network factor 1 in early osteogenesis of mesenchymal stem cells primed by low‐intensity pulsed ultrasound and bone morphogenetic protein 2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is a known reciprocal inhibitory relationship between adipogenesis and osteogenesis in mesenchymal stem cells (MSCs). Our previous study showed that low-intensity pulsed ultrasound (LIPUS) did not promote osteogenesis of a murine MSC line C3H10T1/2, although LIPUS treatment suppressed adipogenesis. Therefore, we investigated the effect of a combination of an osteoinductive factor such as bone morphogenic protein-2 (BMP-2) and LIPUS treatment on osteogenesis. This combination significantly upregulated the gene expressions of BMP receptors and RUNX2, which is a key early osteogenic transcription factor. Interestingly, cellular communication network factor 1 (CCN1) was significantly increased at the mRNA and protein levels. Additionally, Runx2 expression was increased by a recombinant CCN1 protein and decreased in CRISPR-Cas9-generated Ccn1 knockout (KO) cells treated with the combination of LIPUS treatment and BMP-2. Moreover, Runx2 expression was recovered through the transfection of a Ccn1 expression plasmid into Ccn1 KO cells. These findings indicate that treatment with the combination of LIPUS treatment and BMP-2 promoted CCN1 production, and the CCN1 regulates the Runx2 expression in C3H10T1/2 cells, thus suggesting that CCN1 induced by mechanical stimulation and an osteoinductive factor plays a pivotal role in osteogenesis of MSCs. en-copyright= kn-copyright= en-aut-name=PaingHsu Myat en-aut-sei=Paing en-aut-mei=Hsu Myat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakigawaMasaharu en-aut-sei=Takigawa en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=NishidaTakashi en-aut-sei=Nishida 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 Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Faculty 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 Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=BMP‐2 kn-keyword=BMP‐2 en-keyword=CCN1 kn-keyword=CCN1 en-keyword=low‐intensity pulsed ultrasound (LIPUS) kn-keyword=low‐intensity pulsed ultrasound (LIPUS) en-keyword=mesenchymal stem cells kn-keyword=mesenchymal stem cells en-keyword=osteogenic differentiation kn-keyword=osteogenic differentiation END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=2 article-no= start-page=e70089 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=Species‐specific roles of cellular communication network proteins in cartilage development: A comparative study using in vitro chondrogenic models en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular communication network (CCN) proteins are key matricellular regulators of cartilage development, yet their species-specific roles and network-level context remain unclear. This study integrated bulk RNA sequencing from chicken and mouse embryonic limb bud micromass cultures and human mesenchymal stem cell chondrogenesis with co-expression, protein?protein interaction, and ortholog analyses to construct CCN-centered regulatory networks across models. CCN1 and CCN2 emerged as dominant, conserved hubs enriched in collagen-containing extracellular matrix, cartilage development, and growth factor signaling modules, whereas CCN3?CCN6 showed lower context-dependent expression and connectivity. Functional and ortholog analyses revealed moderate pathway conservation, with high conservation of IGF, EGFR, and HIF-1 signaling, but reduced overlap in hypoxia and mechanosensing/Hippo categories, indicating species-specific tuning of environmental sensing. A focused ortholog screen identified multifunctional conserved hubs, including COL2A1, TGFBR1, SMAD3, RUNX2, HIF1A, IGF1, SPP1, and CD44. Single-cell RNA-seq meta-analysis of human iPSC-derived chondrogenesis and embryonic limb datasets showed CCN1/2 expression and homologous network activity peaking in mesenchymal and early chondrocyte populations, consistent with model-dependent persistence into hypertrophic and ossification stages in vivo. Overall, this work defines a conserved CCN1/2-centered axis integrating extracellular matrix formation with growth factor and mechanical cues, providing a framework for model selection and CCN-targeted cartilage regeneration strategies. en-copyright= kn-copyright= en-aut-name=WangZhangzheng en-aut-sei=Wang en-aut-mei=Zhangzheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=V?g?Judit en-aut-sei=V?g? en-aut-mei=Judit kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Tak?csRoland en-aut-sei=Tak?cs en-aut-mei=Roland kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=P?liskaSzil?rd en-aut-sei=P?liska en-aut-mei=Szil?rd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimEe Hyun en-aut-sei=Kim en-aut-mei=Ee Hyun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JinEun‐Jung en-aut-sei=Jin en-aut-mei=Eun‐Jung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KleerCelina G en-aut-sei=Kleer en-aut-mei=Celina G kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=PerbalBernard en-aut-sei=Perbal en-aut-mei=Bernard kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MattaCsaba en-aut-sei=Matta en-aut-mei=Csaba kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Anatomy, Histology and Embryology Faculty of Medicine, University of Debrecen kn-affil= affil-num=2 en-affil=Department of Anatomy, Histology and Embryology Faculty of Medicine, University of Debrecen kn-affil= affil-num=3 en-affil=Department of Anatomy, Histology and Embryology Faculty of Medicine, University of Debrecen kn-affil= affil-num=4 en-affil=Genomic Medicine and Bioinformatics Core Facility Department of Biochemistry and Molecular Biology Faculty of Medicine, University of Debrecen kn-affil= affil-num=5 en-affil=Department of Biomedical Materials Science Graduate School of JABA, Wonkwang University kn-affil= affil-num=6 en-affil=Department of Biomedical Materials Science Graduate School of JABA, Wonkwang University kn-affil= affil-num=7 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University, Faculty of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Department of Pathology, University of Michigan Medical School kn-affil= affil-num=9 en-affil=International CCN Society kn-affil= affil-num=10 en-affil=Department of Anatomy, Histology and Embryology Faculty of Medicine, University of Debrecen kn-affil= en-keyword=cartilage regeneration kn-keyword=cartilage regeneration en-keyword=CCN kn-keyword=CCN en-keyword=chondrogenesis kn-keyword=chondrogenesis en-keyword=osteoarthritis kn-keyword=osteoarthritis en-keyword=regulatory network kn-keyword=regulatory network en-keyword=transcriptomics kn-keyword=transcriptomics END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=44 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=GWAS and Candidate Gene Prediction of Elemental Accumulation Traits in Rice Using a Multiparental Population en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice plants accumulate essential elements to sustain physiological processes during growth and development and to ensure the nutritional quality of the grain as a food source. However, the genetic basis of elemental accumulation and the interrelationships among elemental concentrations across different tissues remain poorly understood. To conduct breeding aimed at improving the absorption characteristics of multiple interrelated elements, genetic analysis using experimental populations that retain diversity while sharing the genetic background of cultivated varieties is effective. Here we show genetic variations in the concentrations of 13 elements (P, K, Ca, Mg, As, Cd, Cr, Cu, Fe, Mo, Mn, Ni, and Zn) in rice straw at the flowering stage and grain at the mature stage using a multi-parent advanced generation inter-cross (MAGIC) population that derived from eight cultivars including both Japonica and Indica. Comprehensive evaluation of the correlation coefficients revealed divergences in the association between grain and straw for several combinations of elements. Haplotype-based genome-wide association studies (GWAS) identified 51 and 53 quantitative trait loci (QTLs) in straw and grain, respectively. In total, the 104 QTLs were grouped into 19 clusters and 60 independent QTLs. By leveraging the haplotype information from the MAGIC population, 52 candidate genes associated with the accumulation of Ca, Mg, Cd, Cu, Fe, and Mo were efficiently predicted from these QTLs, including both previously reported and novel genes. Among them, OsMOT1;1 encoding a molybdenum transporter, was predicted to be within a QTL associated with Mo accumulation in grain on chromosome 8. OsACA9, a homolog of autoinhibited Ca??-ATPases, was predicted within a QTL related to Ca accumulation in straw on chromosome 2. In addition, an unidentified gene, OsCML6, which is presumed to be involved in calcium signaling, was predicted to be a candidate for a Ca-accumulation QTL on chromosome 11. These findings offer insights into haplotypes and putative genes associated with element accumulation and trait interrelationships, providing valuable information for optimizing plant growth and enhancing grain nutritional quality in rice breeding programs. en-copyright= kn-copyright= en-aut-name=ZhangQian en-aut-sei=Zhang en-aut-mei=Qian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurutaTomoyuki en-aut-sei=Furuta en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KashiharaKazunari en-aut-sei=Kashihara en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaDaisuke en-aut-sei=Ogawa en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YonemaruJunichi en-aut-sei=Yonemaru en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoToshio en-aut-sei=Yamamoto en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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 Crop Science, National Agriculture and Food Research Organization kn-affil= affil-num=5 en-affil=Research Center for Agricultural Information Technology, National Agriculture and Food Research Organization kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Rice kn-keyword=Rice en-keyword=Oryza sativa L. kn-keyword=Oryza sativa L. en-keyword=Multi-parent advanced generation inter-cross population kn-keyword=Multi-parent advanced generation inter-cross population en-keyword=Element accumulation kn-keyword=Element accumulation en-keyword=GWAS kn-keyword=GWAS en-keyword=QTL kn-keyword=QTL END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=6 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Report on the seventh Japanese meeting on biological function and evolution through interactions between hosts and transposable elements en-subtitle= kn-subtitle= en-abstract= kn-abstract=The seventh Japanese meeting on host?transposon interactions, titled “Biological Function and Evolution through Interactions between Hosts and Transposable Elements,” was held on September 1st and 2nd, 2025, at the National Institute of Genetics, as well as online.

In this study, 127 bacterial isolates were obtained from barley (Hordeum vulgare L.) roots of two cultivars grown in a non-fertilized field, representing 45 genera and 72 species. Screening identified isolates with growth-promoting, growth-reducing, and neutral phenotypes. Co-inoculation experiments using synthetic communities (SynComs) demonstrated that growth-promoting isolates effectively cancelled the inhibitory effects of growth-reducing isolates on barley seedling growth. Mechanistic investigation revealed that growth-promoting isolates Variovorax sp. 14F-2.1 and Pseudomonas sp. 37A kill growth-reducing isolates Flavobacterium sp. 2D-1 through direct cell-to-cell contact. Deletion of the Type VI secretion system (T6SS) gene tssA in Variovorax sp. 14F-2.1 substantially reduced this activity, implicating T6SS as a key antagonistic mechanism. Phytohormone profiling revealed that growth-promoting and neutral isolates, but not growth-reducing isolates, produce cytokinins, and only Variovorax sp. 14F-2.1 could degrade IAA, suggesting a potential hormonal basis for differential growth effects. A two-year field microbiome study showed that fertilization regimen and seasonal sampling times were dominant drivers of rhizosphere community composition, while bacterial inoculation had limited and inconsistent effects on microbial diversity and plant growth under field conditions. These results demonstrate that interbacterial antagonism is a key determinant of community-level plant growth outcomes and highlight the complexity of translating laboratory inoculant effects to field settings. en-copyright= kn-copyright= en-aut-name=MahamudMd Asif en-aut-sei=Mahamud en-aut-mei=Md Asif kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PichaikarnRungnapa en-aut-sei=Pichaikarn en-aut-mei=Rungnapa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LatifMuhammad Ammar en-aut-sei=Latif en-aut-mei=Muhammad Ammar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriIzumi C en-aut-sei=Mori en-aut-mei=Izumi C kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaishoDaisuke en-aut-sei=Saisho en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UngcharoenwiwatPakpimol en-aut-sei=Ungcharoenwiwat en-aut-mei=Pakpimol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=School of Science, Walailak 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 Science and Resources, Okayama University 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= affil-num=7 en-affil=School of Science, Walailak University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Barley kn-keyword=Barley en-keyword=Rhizosphere microbiome kn-keyword=Rhizosphere microbiome en-keyword=SynCom kn-keyword=SynCom en-keyword=Bacterial antagonism kn-keyword=Bacterial antagonism en-keyword=Type VI secretion system kn-keyword=Type VI secretion system en-keyword=Phytohormone kn-keyword=Phytohormone END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=94 end-page=99 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimization of the External Directing Group Depending on the Substrates for the Regioselective C?H Alkenylation of Phenyl Ethers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Using an external directing group (externalDG), we have succeeded in ortho-selective C?H alkenylation of various DG-free phenyl ethers, including bulky silyl ethers.

However, TMP?SMX?related adverse events frequently complicate long-term therapy, and real-world data regarding treatment continuity and outcomes remain limited. Methods: We conducted a retrospective observational study of patients with Nocardia species isolated from clinical specimens at a tertiary-care academic hospital in Japan between January 2015 and April 2025. Clinical characteristics, antimicrobial therapy, adverse events, and outcomes were reviewed.
Results: Eleven cases were enrolled, with a median age of 65 years. The cohort comprised seven patients with severe nocardiosis (disseminated disease, brain abscess, and pneumonia in transplant recipients) and four patients with mild nocardiosis (cutaneous infection and pneumonia). Nine patients received TMP?SMX as part of the initial regimen, of whom seven required modification of therapy within 1 day to 3 months because of adverse events. Following modification of TMP?SMX, patients were treated with alternative regimens, including fluoroquinolone?and minocycline-based therapies, as well as β-lactam?containing combinations. Importantly, no cases of treatment failure or death were observed, and no relapses were identified during the available follow-up period, even among patients with those clinically complex diseases.
Conclusions: Although TMP?SMX is the first-line therapy for nocardiosis, the majority of our patients did not tolerate the drug. Nevertheless, favorable outcomes were observed with alternative regimens, even in patients with clinically complex disease, suggesting that alternative regimens may be reasonable options when TMP?SMX is not tolerated. 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=MiyaharaTomoyuki en-aut-sei=Miyahara en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgawaSakura en-aut-sei=Ogawa en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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 Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Nocardiosis kn-keyword=Nocardiosis en-keyword=Treatment kn-keyword=Treatment en-keyword=Trimethoprim?sulfamethoxazole kn-keyword=Trimethoprim?sulfamethoxazole en-keyword=Alternative therapy kn-keyword=Alternative therapy en-keyword=Dose modification kn-keyword=Dose modification 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=20260509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fenestration Re-creation for Early Fontan Deterioration: Long-Term Hemodynamic and Clinical Outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spontaneous closure of a Fontan fenestration may precipitate early hemodynamic deterioration in vulnerable patients. In such situations, fenestration re-creation may be considered as a rescue strategy when medical therapy is insufficient. However, the long-term hemodynamic consequences of this intervention remain poorly defined. We retrospectively reviewed 62 patients who underwent the Fontan procedure between January 2011 and December 2020 and subsequently experienced spontaneous fenestration closure. Patients were divided into two groups according to management strategy: those who underwent fenestration re-creation (Group 1, n?=?19) and those managed without re-creation (Group 2, n?=?43). Longitudinal hemodynamic data were analyzed using linear mixed models over a median follow-up of 10.2 years. Fenestration closed spontaneously at a median of 12 days (IQR 2.5?26.5) and initial re-creation was performed at the median of 42 days (IQR 11?213) postoperatively. Early and mide-term hemodynamic trends were broadly similar between groups, however, clear divergence emerged in the late follow-up. fenestration re-created patients demonstrated persistently higher central venous pressure and pulmonary vascular resistance, lower systemic vascular resistance, progressive increases in cardiac index, and declining oxygen saturation. Survival in this group remained above 80% during the mid-term follow-up but declined substantially in the late phase compared with patients without re-creation (52% vs. 85%, p?=?0.043). This was accompanied by higher incidences of protein-losing enteropathy/plastic bronchitis, thromboembolism, and severe cyanosis. Fenestration re-creation may provide temporary hemodynamic stabilization in early Fontan deterioration; however, its benefits appear to diminish in the late phase. These findings highlight the need for hemodynamically tailored management strategies and alternative therapeutic options for patients with deteriorating Fontan circulation. en-copyright= kn-copyright= en-aut-name=TranThi Hai Yen en-aut-sei=Tran en-aut-mei=Thi Hai Yen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuritaYoshihiko en-aut-sei=Kurita en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoMaiko en-aut-sei=Kondo en-aut-mei=Maiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaYosuke en-aut-sei=Fukushima en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigemitsuYusuke en-aut-sei=Shigemitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawamotoYuya en-aut-sei=Kawamoto en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HaraMayuko en-aut-sei=Hara en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwasakiTatsuo en-aut-sei=Iwasaki en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BabaKenji en-aut-sei=Baba en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Pediatrics, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Pediatric anesthesiology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Cardiovascular Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Fontan operation kn-keyword=Fontan operation en-keyword=Spontaneous fenestration closure kn-keyword=Spontaneous fenestration closure en-keyword=Fenestration recreation kn-keyword=Fenestration recreation en-keyword=Longitudinal hemodynamic changes kn-keyword=Longitudinal hemodynamic changes END start-ver=1.4 cd-journal=joma no-vol=1867 cd-vols= no-issue=4 article-no= start-page=149598 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cryo-EM structure of photosystem II D1-V185T mutant from Thermosynechococcus vestitus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) catalyzes water oxidation into electrons, protons and dioxygen at its catalytic center, a Mn4CaO5 cluster, utilizing light energy. An amino acid residue D1-V185 in the D1 protein is located close to the Mn4CaO5 cluster, and plays a critical role in its catalytic function. In this research we purified PSII dimers from a D1-V185T mutant of Thermosynechococcus vestitus and analyzed its structure using low-damage cryo-electron microscopy (cryo-EM) at a resolution of 1.88 ?. The results revealed the presence of multi-conformations at the mutation site. Unlike the wild-type valine, which does not allow water molecules to be able to form hydrogen-bonds with it, both conformations of the mutant formed hydrogen bonds with nearby water molecules, which leads to rearrangement of the hydrogen bond networks in the O1 and Cl-1 channels. In conformation-A, the mutated Thr residue forms a hydrogen bond with a water molecule W6, which creates a new channel that bypasses the original O1 channel. Due to the hydrophilic OH group of Thr, the side-chain of D1-Glu189 was attracted and shifted toward the mutant Thr residue. In conformation-B, it forms a hydrogen bond with a water molecule W9 in the Cl-1 channel, bringing W9 closer and thereby disrupting the hydrogen bond network of the Cl-1 channel. In addition, multi-conformations of D2-K317, which is a ligand of Cl-1, were found in the mutant. These changes alter the environment surrounding the Cl-1 ion and Mn4CaO5, thereby affecting the PSII water-oxidation activity. en-copyright= kn-copyright= en-aut-name=JiangHaowei en-aut-sei=Jiang en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkitaFusamichi en-aut-sei=Akita en-aut-mei=Fusamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiHongjie en-aut-sei=Li en-aut-mei=Hongjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiuraMiwa en-aut-sei=Sugiura en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 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=2 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=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=Center for Transformative Science, School of Life Science and Technology and Shanghai Clinical Research and Trial Center, ShanghaiTech University kn-affil= affil-num=5 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=6 en-affil=Proteo-Science Research Center, Ehime University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=Oxygen-evolving complex kn-keyword=Oxygen-evolving complex en-keyword=Water-oxidation kn-keyword=Water-oxidation en-keyword=Structure kn-keyword=Structure en-keyword=Mutant kn-keyword=Mutant en-keyword=Cryo-EM kn-keyword=Cryo-EM en-keyword=Thermosynechococcus vestitus kn-keyword=Thermosynechococcus vestitus END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=22258 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260711 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microstructural changes in irradiated teeth revealed by swept-source optical coherence tomography en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radiation-induced caries is a late complication of radiotherapy for head and neck cancers. Although direct irradiation-induced changes in tooth structure may contribute to its development, these changes have not been fully characterized. This study evaluated irradiation-associated microstructural alterations and tissue density changes in human teeth using swept-source optical coherence tomography (SS-OCT). Eight extracted fully impacted human third molars were assigned to irradiated and non-irradiated groups (n?=?4 each). The irradiated group received X-rays at a total dose of 70 Gy, a clinically relevant dose in definitive radiotherapy for head and neck cancer. A total of 64 SS-OCT cross-sectional images were obtained and analyzed, with 32 images from each group, including 16 from the coronal area on the occlusal side and 16 from the cervical area. Microcrack-like features were observed in 100% (16/16) of irradiated and 31.3% (5/16) of non-irradiated images in the coronal area on the occlusal side, and in 43.8% (7/16) and 0% (0/16) of images in the cervical area, respectively. Attenuation coefficients were significantly higher in irradiated enamel and dentin. These findings suggest that irradiation-induced microstructural changes in extracted human teeth in vitro may contribute to increased susceptibility to radiation-induced caries. en-copyright= kn-copyright= en-aut-name=MatsuzakiKumiko en-aut-sei=Matsuzaki en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuzakiHidenobu en-aut-sei=Matsuzaki en-aut-mei=Hidenobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TabataTomoko en-aut-sei=Tabata en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AoyamaHideki en-aut-sei=Aoyama en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshioKotaro en-aut-sei=Yoshio en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KosakiHirotaka en-aut-sei=Kosaki en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OharaNaoko en-aut-sei=Ohara en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SadrAlireza en-aut-sei=Sadr en-aut-mei=Alireza kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShimadaYasushi en-aut-sei=Shimada en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cariology and Operative Dentistry, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=4 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Operative Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Biomimetics Biomaterials Biophotonics Biomechanics & Technology Laboratory, Department of Restorative Dentistry, Magnuson Health Sciences Center, University of Washington kn-affil= affil-num=9 en-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Cariology and Operative Dentistry, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= en-keyword=Radiation-induced caries kn-keyword=Radiation-induced caries en-keyword=Dental enamel kn-keyword=Dental enamel en-keyword=Dentin kn-keyword=Dentin en-keyword=Radiation effects kn-keyword=Radiation effects en-keyword=Swept-source optical coherence tomography kn-keyword=Swept-source optical coherence tomography END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue=2 article-no= start-page=58 end-page=61 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case of autoamputated primary uterine diffuse large B-cell lymphoma treated with Pola-R-CHP therapy and CNS recurrence prophylaxis kn-title=自然脱落した子宮原発 DLBCL に対して Pola-R-CHP 療法と CNS 再発予防を行った１例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　A 55-year-old woman presented to her local physician with the chief complaint of genital bleeding. A 22×19-mm mass was noted on the patient's cervix, and during the internal examination the mass auto-amputated. The pathological examination of the auto-amputated mass revealed diffuse large B-cell lymphoma (DLBCL). An examination by F-fluorodeoxyglucose-positron emission tomography-computed tomography (FDG-PET-CT) showed FDG uptake at physiological levels in the cervix, with no abnormal uptake in other organs. Cervical tissue was sampled after the spontaneous detachment of the cervical mass, and the biopsy of the cervical mass did not reveal findings suggestive of lymphoma. Six courses of chemotherapy with polatuzumab vedotin, rituximab, cyclophosphamide, doxorubicin, and prednisolone (Pola-R-CHP) plus an intramedually injection of methotrexate, cytarabine, and predonisolone (IT-triple), followed by two courses of high-dose intrathecal methotrexate (HD-MTX) were adiministered, and the patient has remained recurrence-free for the more than 8 months since the completion of this treatment. Primary uterine DLBCL is an extremely rare disease with a high rate of recurrence in the central nervous system and a poor prognosis. Our search of the relevant literature identified very few reports describing the prognoses of cases with spontaneous tumor detachment. en-copyright= kn-copyright= en-aut-name=OsadaHikaru en-aut-sei=Osada en-aut-mei=Hikaru kn-aut-name=長田晃 kn-aut-sei=長田 kn-aut-mei=晃 aut-affil-num=1 ORCID= en-aut-name=KimuraMaiko en-aut-sei=Kimura en-aut-mei=Maiko kn-aut-name=木村真衣子 kn-aut-sei=木村 kn-aut-mei=真衣子 aut-affil-num=2 ORCID= en-aut-name=MuneishiManaka en-aut-sei=Muneishi en-aut-mei=Manaka kn-aut-name=宗石愛花 kn-aut-sei=宗石 kn-aut-mei=愛花 aut-affil-num=3 ORCID= en-aut-name=MurayamaKozo en-aut-sei=Murayama en-aut-mei=Kozo kn-aut-name=村山晃三 kn-aut-sei=村山 kn-aut-mei=晃三 aut-affil-num=4 ORCID= en-aut-name=NiiyaDaigo en-aut-sei=Niiya en-aut-mei=Daigo kn-aut-name=新谷大悟 kn-aut-sei=新谷 kn-aut-mei=大悟 aut-affil-num=5 ORCID= en-aut-name=TakeuchiMakoto en-aut-sei=Takeuchi en-aut-mei=Makoto kn-aut-name=竹内誠 kn-aut-sei=竹内 kn-aut-mei=誠 aut-affil-num=6 ORCID= en-aut-name=FujiiSoichiro en-aut-sei=Fujii en-aut-mei=Soichiro kn-aut-name=藤井総一郎 kn-aut-sei=藤井 kn-aut-mei=総一郎 aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 affil-num=2 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 affil-num=3 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 affil-num=4 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 affil-num=5 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 affil-num=6 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 affil-num=7 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=岡山赤十字病院　血液内科 en-keyword=びまん性大細胞型Ｂ細胞リンパ腫 (diffuse large B-cell lymphoma) kn-keyword=びまん性大細胞型Ｂ細胞リンパ腫 (diffuse large B-cell lymphoma) en-keyword=子宮原発リンパ腫 (primary uterine lymphoma) kn-keyword=子宮原発リンパ腫 (primary uterine lymphoma) en-keyword=Pola-R-CHP療法 (Pola-R-CHP regimen) kn-keyword=Pola-R-CHP療法 (Pola-R-CHP regimen) en-keyword=HD-MTX療法 (HD-MTX regimen) kn-keyword=HD-MTX療法 (HD-MTX regimen) END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue=2 article-no= start-page=31 end-page=34 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2025 Incentive Award of the Okayama Medical Association in General Medical Science (2025 Yuuki Prize) kn-title=令和７年度岡山医学会賞　総合研究奨励賞（結城賞） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KambaraYui en-aut-sei=Kambara en-aut-mei=Yui kn-aut-name=神原由依 kn-aut-sei=神原 kn-aut-mei=由依 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科　血液・腫瘍・呼吸器内科学 END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue= article-no= start-page=1842408 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=New mechanistic insight into SARM1 activation: TRIM32-mediated ubiquitination is a key lever that actuates SARM1’s catalytic action, leading to axon degeneration and cell death en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sterile alpha and TIR motif-containing protein 1 (SARM1) is an enzyme that cleaves nicotinamide adenine dinucleotide (NAD+) and plays a role in disrupting neural circuits through axon degeneration and cell death. SARM1 is activated by changes in the nicotinamide mononucleotide (NMN)/NAD+ ratio and by various post-translational modifications, but its complete regulatory mechanism remains poorly understood. Here, we report that tripartite motif-containing protein 32 (TRIM32) activates SARM1 through specific ubiquitination triggered by anticancer drug treatment. TRIM32 promotes the attachment of Lys27-linked ubiquitin chains to Lys173 and Lys375 within the ARM domain, which is an autoinhibitory region of SARM1. This ubiquitination by TRIM32 increases SARM1’s NAD+-cleaving catalytic activity and enhances its ability to induce neurite degeneration and cell death. A mutant form of TRIM32 lacking the enzymatically active RING domain fails to promote SARM1 ubiquitination, and reducing TRIM32 levels decreases SARM1 ubiquitination. Additionally, ubiquitin-specific peptidase 13 (USP13), a known negative regulator of SARM1, can deubiquitinate SARM1. These findings suggest that TRIM32 is a key regulator of axon degeneration and cell death through its ubiquitination of SARM1. en-copyright= kn-copyright= en-aut-name=MurataHitoshi en-aut-sei=Murata en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomonobuNahoko en-aut-sei=Tomonobu en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoKen-ichi en-aut-sei=Yamamoto en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinoshitaRie en-aut-sei=Kinoshita en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=axon degeneration kn-keyword=axon degeneration en-keyword=NAD?+ kn-keyword=NAD?+ en-keyword=SARM1 kn-keyword=SARM1 en-keyword=TRIM32 kn-keyword=TRIM32 en-keyword=ubiquitination kn-keyword=ubiquitination END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Potential effects of intradialytic exercise therapy on physical performance in hemodialysis patients based on the intervention period: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Intradialytic exercise during hemodialysis (HD) improves physical function and shows high adherence. In Japan, the 2018 guideline by the Japanese Society of Renal Rehabilitation supports intradialytic exercise, but medical insurance only covers the first 90 days. As new studies have emerged since the guideline was published, we conducted a systematic review and meta-analysis to evaluate the impact and optimal duration of exercise interventions beyond 12 weeks.
Methods We followed a preregistered protocol (PROSPERO CRD42025642273) and PRISMA-P guidelines. Randomized controlled trials of adult patients undergoing HD performing structured exercise were identified via MEDLINE database (PubMed, March 2017?November 2024) and ICHUSHI-Web database. Two independent reviewers screened studies, extracted data, and assessed risk of bias using Cochrane RoB 2.0. Outcomes included peak oxygen uptake (VO2peak), maximal oxygen uptake (VO2max), 6 min walk distance, timed up and go (TUG) test, handgrip strength, sit-to-stand (STS) performance, and biochemical measures (hemoglobin, standard weekly urea Kt/V [std Kt/V]). Pooled mean differences (MD) with 95% confidence intervals (CI) were calculated using a mixed-effects model (Hartung?Knapp?Sidik?Jonkman method).
Results A total of 71 studies, including 43 newly identified studies, were included. Risk of bias was moderate-to-high. Interventions?>?12 weeks significantly improved 6 min walking distance (MD 52.4 m [95% CI 35.4?69.3], p??12 weeks of exercise.
Conclusions Our findings suggest that exercise interventions lasting more than 12 weeks can enhance physical performance. Nevertheless, the applicability of these results to older patients remains uncertain, as most evidence is derived from middle-aged cohorts.

Structured exercise therapy is recommended, but domain-specific effects and the influence of intervention duration remain uncertain. This study evaluated the impact of structured exercise therapy on multiple HRQoL domains, including fatigue and depression, stratified by intervention duration.
Methods: We conducted a systematic review and meta-analysis, searching MEDLINE (PubMed) through November 2024. The protocol was registered in PROSPERO (CRD42025642273). We included trials comparing structured exercise with non-exercise controls in adult HD patients. Primary outcomes were Short Form (SF)-36 Physical and Mental Component Summaries (PCS, MCS), fatigue, pain, general health, and depression (Beck Depression Inventory). Data were synthesized using random-effects models, stratified by intervention duration (??3 versus?>?3 months). Risk of bias was assessed using the Cochrane RoB 2 tool.
Results: We identified 94 randomized controlled trials (5228 participants); 22 reported HRQoL outcomes and were meta-analyzed. Exercise significantly improved fatigue (mean difference [MD]?+?7.27, 95% confidence interval [CI] 4.75?9.80) and reduced depressive symptoms in?>?3-month trials (MD??7.62, 95% CI??8.34 to??6.90); no???3-month depression data were available. In overall analyses, general health (MD?+?11.59, 95% CI 6.98?16.21) and PCS (MD?+?5.83, 95% CI 0.71?10.94) improved, whereas MCS (MD?+?7.60, 95% CI??3.75 to 18.94) and pain (MD?+?2.19, 95% CI??4.41 to 8.79) showed no clear benefit. Short-term interventions (??3 months) yielded significant improvements in pain and general health. In longer-term interventions (>?3 months), general health estimates were similar in magnitude but statistically nonsignificant, and pain effects were also nonsignificant with substantial heterogeneity. Fatigue improved in both duration strata.
Conclusions: Structured exercise therapy appears to improve fatigue in patients on maintenance HD and may provide additional gains in PCS and general health with interventions longer than 3 months. Improvements in depressive symptoms were observed from limited evidence, and duration-specific effects remain uncertain because no trials assessed depression at???3 months. Effects on pain and MCS remain uncertain owing to substantial heterogeneity. Larger long-term trials are needed to clarify the sustainability of HRQoL benefits beyond 3 months. en-copyright= kn-copyright= en-aut-name=HondaYu en-aut-sei=Honda en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KojimaShigeki en-aut-sei=Kojima en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeHiromasa en-aut-sei=Miyake en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimotoMasatoshi en-aut-sei=Nishimoto en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HishikawaAkihito en-aut-sei=Hishikawa en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TonomuraShun en-aut-sei=Tonomura en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SofueTadashi en-aut-sei=Sofue en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiNaohiko en-aut-sei=Fujii en-aut-mei=Naohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SaitohMasakazu en-aut-sei=Saitoh en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NaritaIchiei en-aut-sei=Narita en-aut-mei=Ichiei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamagataKunihiro en-aut-sei=Yamagata en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HoshinoJunichi en-aut-sei=Hoshino en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KawarazakiHiroo en-aut-sei=Kawarazaki en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SakuradaTsutomu en-aut-sei=Sakurada en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Division of Nephrology and Hypertension, Department of Internal Medicine, The Jikei University School of Medicine kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Teikyo University Hospital Mizonokuchi kn-affil= affil-num=3 en-affil=Kojima Kidney and Dialysis Clinic kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Nara Medical University kn-affil= affil-num=6 en-affil=Department of Endocrinology, Metabolism and Nephrology, Keio University School of Medicine kn-affil= affil-num=7 en-affil=Department of Endocrinology, Metabolism and Nephrology, Keio University School of Medicine kn-affil= affil-num=8 en-affil=Department of Cardiorenal and Cerebrovascular Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Department of Nephrology, Hyogo Prefectural Nishinomiya Hospital kn-affil= affil-num=10 en-affil=Department of Physical Therapy, Faculty of Health Science, Juntendo University kn-affil= affil-num=11 en-affil=Niigata Institute for Health and Sports Medicine, Niigata Sports Association kn-affil= affil-num=12 en-affil=Department of Nephrology, Institute of Medicine, University of Tsukuba kn-affil= affil-num=13 en-affil=Department of Nephrology, Tokyo Women’s Medical University kn-affil= affil-num=14 en-affil=Department of Internal Medicine, Teikyo University Hospital Mizonokuchi kn-affil= affil-num=15 en-affil=Division of Nephrology and Hypertension, Department of Internal Medicine, St. Marianna University School of Medicine kn-affil= en-keyword=Hemodialysis kn-keyword=Hemodialysis en-keyword=Exercise therapy kn-keyword=Exercise therapy en-keyword=Intradialytic exercise kn-keyword=Intradialytic exercise en-keyword=Health-related quality of life kn-keyword=Health-related quality of life en-keyword=Fatigue kn-keyword=Fatigue en-keyword=Depression kn-keyword=Depression en-keyword=Randomized controlled trials kn-keyword=Randomized controlled trials en-keyword=Meta-analysis kn-keyword=Meta-analysis END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=2 article-no= start-page=527 end-page=535 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Microcontroller-Integrated Multichannel Time Detector for Paper-Based Analytical Devices ? Applications to Viscosity Measurements in Saliva Analysis and Protease-Activity Assays en-subtitle= kn-subtitle= en-abstract= kn-abstract=We designed and developed a microcontroller-integrated multichannel time detection system that uses a microfluidic paper-based analytical device (?PAD) to measure liquid viscosity. This detection system is equipped with ten detectors to enhance the throughput of the measurements. The ?PAD utilizes capillary action to determine viscosity based on the flow time of a liquid sample. A conductivity detection system begins counting the flow time when a sample is introduced and stops the count when the sample reaches the detection electrode. Sodium chloride (NaCl) was pre-deposited in the detection channel of the ?PAD to enhance the conductivity of non-conductive samples, and Grade 1 CHR chromatography paper was selected as the optimal vehicle for substrates after comparing various channel widths, paper types, and channel lengths. The device demonstrated a linear correlation between flow time and viscosity for bovine serum albumin (BSA) and glucose solutions, which validates the theoretical model. The time readout measured protease activity when gelatin was used as a substrate and revealed an activity order of bromelain?>?papain?>?trypsin. The practical applicability of this system was further confirmed by testing real saliva samples, which demonstrated that the viscosity of saliva decreases rapidly after collection. Moreover, the results indicate that saliva viscosity was increased during extended durations of exercise. Overall, this ?PAD system provides a simple, low-cost, and portable solution for viscosity measurement, with potential applications in clinical diagnostics and field measurements. en-copyright= kn-copyright= en-aut-name=RenJianchao en-aut-sei=Ren en-aut-mei=Jianchao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Paper-based analytical device kn-keyword=Paper-based analytical device en-keyword=Time detector kn-keyword=Time detector en-keyword=Multichannel kn-keyword=Multichannel en-keyword=Viscosity kn-keyword=Viscosity en-keyword=Enzyme assay kn-keyword=Enzyme assay en-keyword=Saliva kn-keyword=Saliva END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=12 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knockout analysis of period and timeless and EGFP-based visualization of per-expressing clock cells in the cricket circadian clock en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the present study, we generated crickets with knockout of either period (per) or timeless (tim) gene by CRISPR/Cas9-based genome editing. We also identified a naturally occurring per- mutant lacking a large coding region including PAS domains. To examine possible synergistic effects, a per- and timKO double mutant was generated by applying genome editing to the per- crickets. Under constant darkness (DD), timKO crickets exhibited a locomotor rhythm with a free-running period of 23.06?±?0.20?h (mean?±?SD), which was significantly shorter than that of the parental strain (23.78?±?0.12?h). By contrast, perKO and per- crickets showed basically similar phenotype of locomotor rhythm: they exhibited an arrhythmic pattern during the first two to three weeks after transfer to DD but subsequently showed a complex rhythmic pattern with one or multiple components with significantly longer free-running periods (33.35?±?10.72?h). In the per-;timKO double mutants, approximately 60% of individuals became arrhythmic, while the remaining 40% exhibited complex rhythms with extremely longer free-running periods (37.0?±?9.17?h) under DD. These results suggest the existence of an underlying oscillatory mechanism that is responsible for regulating locomotor rhythms independently of the canonical per/tim feedback loop. Furthermore, we generated a reporter line on a per? background by knocking egfp into exon 1 of the per gene, allowing egfp expression to report per transcription. EGFP expression was detected in three distinct clusters of cells within the optic lobe: two located along the dorsal and ventral boundaries between the lamina and medulla neuropils, and one situated near the accessory medulla. These findings raise the possibility that these form part of the circadian clock network that governs circadian locomotor rhythms. en-copyright= kn-copyright= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueShintaro en-aut-sei=Inoue en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitoTaro en-aut-sei=Mito en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriyamaYoshiyuki en-aut-sei=Moriyama en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Bio-Innovation Research Center, Tokushima University kn-affil= affil-num=3 en-affil=Bio-Innovation Research Center, Tokushima University kn-affil= affil-num=4 en-affil=Department of Natural Sciences, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Circadian clock kn-keyword=Circadian clock en-keyword=Cricket kn-keyword=Cricket en-keyword=Genome editing kn-keyword=Genome editing en-keyword=Locomotor rhythm kn-keyword=Locomotor rhythm en-keyword=period kn-keyword=period en-keyword=per-less oscillation kn-keyword=per-less oscillation en-keyword=timeless kn-keyword=timeless END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=3 article-no= start-page=e71081 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=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=384 cd-vols= no-issue= article-no= start-page=114996 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=Alternative transcription of the mouse Gh gene identifies an immune-associated transcript with species-specific structural divergence en-subtitle= kn-subtitle= en-abstract= kn-abstract=Growth hormone (GH) in mice is primarily expressed in the anterior pituitary, although Gh expression has been reported in extrapituitary tissues, including immune organs. However, the structure of immune-associated Gh transcripts remains poorly characterized. To determine whether splenic Gh transcripts differ from pituitary Gh mRNA, 5′- and 3′-rapid amplification of cDNA ends (RACE) analyses were performed. While 3′ RACE showed a shared polyadenylation site, 5′ RACE identified a novel exon located approximately 2 kb upstream of the conventional exon 1, generating a transcript (spl-Gh mRNA) with a distinct first exon but shared downstream exons with pituitary Gh mRNA (pit-Gh mRNA). RT-PCR analysis revealed that spl-Gh mRNA is predominantly expressed in immune tissues such as spleen and bone marrow, and its distribution did not correlate with Pit-1 mRNA expression. Quantitative RT-PCR further demonstrated that spl-Gh mRNA was expressed at levels comparable to those of pit-Gh mRNA in the mouse spleen, indicating that spl-Gh is one of the major Gh transcript forms in this tissue. Sequence analysis indicated that spl-Gh mRNA is predicted to retain coding potential for a GH protein. Comparative genomic analyses further demonstrated that genomic features associated with the spl-Gh transcriptional unit are conserved only in a subset of closely related Mus species. In contrast, although a spl-Gh?related transcript was detected in rat spleen, no properly spliced mouse-like transcript was identified under the present experimental conditions. The detected transcript exhibited intron retention and an in-frame stop codon, suggesting that it is unlikely to produce a functional GH protein. These findings identify a distinct immune-associated Gh transcript generated through alternative transcription of the mouse Gh gene and suggest that immune-associated Gh transcriptional mechanisms have undergone species-specific divergence among rodents. Together, these findings reveal previously unrecognized complexity in Gh gene regulation and highlight species-specific differences in immune-associated Gh transcripts. en-copyright= kn-copyright= en-aut-name=FukushimaAi en-aut-sei=Fukushima en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiYu en-aut-sei=Takeuchi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuchiHibiki en-aut-sei=Fukuchi en-aut-mei=Hibiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EgoshiSakura en-aut-sei=Egoshi en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=AizawaSayaka en-aut-sei=Aizawa en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeuchiSakae en-aut-sei=Takeuchi en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Growth hormone kn-keyword=Growth hormone en-keyword=Alternative transcription kn-keyword=Alternative transcription en-keyword=Immune-associated transcript kn-keyword=Immune-associated transcript en-keyword=Extrapituitary expression kn-keyword=Extrapituitary expression en-keyword=Species-specific divergence kn-keyword=Species-specific divergence en-keyword=Mouse kn-keyword=Mouse END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=893 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural insights into tRNA recognition of the human FTSJ1-THADA complex en-subtitle= kn-subtitle= en-abstract= kn-abstract=tRNA undergoes various post-transcriptional modifications in the anticodon loop. FTSJ1, a protein conserved among most eukaryotes, mediates 2’-O-methylations at position 32 (Nm32) or position 34 (Nm34), complexed with THADA or WDR6, respectively. These methylations are crucial for accurate translation and cellular growth. FTSJ1 mutations are associated with non-syndromic X-linked intellectual disability. Although the structure of the FTSJ1-WDR6 complex in yeast has been solved, the structural details of the FTSJ1-THADA complex formation and substrate recognition remain unclear. Herein, using cryo-electron microscopy, we solve the high-resolution structure of FTSJ1-THADA with or without a tRNA substrate. FTSJ1 binds to THADA via its C-terminal region, with a unique interaction mode distinct from the FTSJ1-WDR6 complex. The tRNA substrate is anchored inside THADA, and key THADA residues for THADA-tRNA interaction are identified via structural and biochemical analyses. These findings demonstrate how FTSJ1 and THADA form a complex to mediate Nm32 modification in various tRNAs. en-copyright= kn-copyright= en-aut-name=IshiguroKensuke en-aut-sei=Ishiguro en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirouzuMikako en-aut-sei=Shirouzu en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Laboratory for Protein Functional and Structural Biology, RIKEN Center for Biosystems Dynamics Research kn-affil= affil-num=2 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Laboratory for Protein Functional and Structural Biology, RIKEN Center for Biosystems Dynamics Research kn-affil= END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=11 article-no= start-page=1302 end-page=1313 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trastuzumab-Pertuzumab Plus Eribulin or Taxane as First-Line Chemotherapy for Human Epidermal Growth Factor 2?Positive Locally Advanced/Metastatic Breast Cancer: The Randomized Noninferiority Phase III EMERALD Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Trastuzumab-pertuzumab (HP) plus taxane is a current standard first-line therapy for recurrent or metastatic human epidermal growth factor 2 (HER2)+ breast cancer (BC). We investigated noninferiority of eribulin to a taxane when combined with dual HER2 blockade as first-line systemic treatment for locally advanced/metastatic HER2+ BC.
Methods In the phase III EMERALD trial (target sample size, 480; ClinicalTrials.gov identifier: NCT03264547/UMIN000027938), patients were randomly assigned (1:1) to receive eribulin 1.4 mg/m2 once daily on days 1 and 8 (eribulin group) or a taxane (docetaxel 75 mg/m2 once on day 1 or paclitaxel 80 mg/m2 once daily on days 1, 8, and 15; taxane group) intravenously in a 21-day cycle, each with HP on day 1. The primary end point was progression-free survival (PFS; intention-to-treat population). Secondary end points included objective response rate, overall survival (OS), patient-reported quality of life (QoL), and safety. Noninferiority was tested using the stratified Cox proportional hazards model to estimate hazard ratios (HRs) for PFS events, with a noninferiority HR margin of 1.33.
Results Between August 2017 and June 2021, 446 patients (median age, 56.0 years) were enrolled. The median PFS was 14.0 and 12.9 months in the eribulin group (n = 224) and taxane group (n = 222 [docetaxel/paclitaxel, n = 186/36]), respectively (HR, 0.95 [95% CI, 0.76 to 1.19]), which confirmed the noninferiority of the study regimen. The median OS was 65.3 months in the taxane group but has not been reached in the eribulin group. Median time to QoL deterioration was numerically longer with eribulin than with taxane. Adverse event (AE) rates were similar, despite the longer duration of eribulin use. Infusion reaction, skin-related AEs, diarrhea, and edema were more common with taxane, whereas neutropenia was more common with eribulin.
Conclusion The results suggested that eribulin + HP is an option for first-line treatment of locally advanced/metastatic HER2+ BC. en-copyright= kn-copyright= en-aut-name=YamashitaToshinari

Generates Nitric Oxide through Natural Radiation of Far Infrared Rays, Reducing Serum Glucose, Cholesterol, and Triglycerides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Toloese, a bed composition, is formulated with a combination of minerals of various wavelengths by utilizing a specific ratio and particle size. A maturation mixing technique is used without additional compression processes, resulting in the natural formation of numerous fine pores in the bed structure. At 40 °C, far infrared radiation in the range of 5?20 μm is emitted with a 0.916 radiant ratio, and the measured emitted radiant energy is 3.69 × 102 W/m2?μm. This study aimed to investigate the influence of far infrared radiation emitted from a Toloese bed on endogenous nitric oxide production. Clinical trials were conducted with 20 healthy adults aged 20 years. Blood samples were collected before and after Toloese bed usage for 1 h daily for 3 weeks. Nitric oxide levels in the saliva and blood of men and women significant increased after they used the Toloese bed for 1 h. Additionally, sweating sharply increased in the upper and lower body regions after Toloese bed usage. No hematological changes or adverse effects were observed, but blood glucose, cholesterol, and triglycerides decreased after Toloese bed usage compared with those before Toloese bed usage. These findings demonstrated that far infrared radiation emitted by the Toloese bed induced endogenous nitric oxide production and contributed to significant reductions in blood glucose, cholesterol, and triglyceride levels. en-copyright= kn-copyright= en-aut-name=YeoMin-Ho en-aut-sei=Yeo en-aut-mei=Min-Ho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LeeYoung-Hyeon en-aut-sei=Lee en-aut-mei=Young-Hyeon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RyuMi-Jin en-aut-sei=Ryu en-aut-mei=Mi-Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChoiYong-Hak en-aut-sei=Choi en-aut-mei=Yong-Hak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimHye-Sook en-aut-sei=Kim en-aut-mei=Hye-Sook kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChangKyung-Soo en-aut-sei=Chang en-aut-mei=Kyung-Soo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Clinical Laboratory Science, Catholic University of Pusan kn-affil= affil-num=2 en-affil=Department of Clinical Laboratory Science, Catholic University of Pusan kn-affil= affil-num=3 en-affil=Department of Clinical Laboratory Science, Catholic University of Pusan kn-affil= affil-num=4 en-affil=SayM Co., Ltd. kn-affil= affil-num=5 en-affil=Division of International Infectious Diseases Control, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Clinical Laboratory Science, Catholic University of Pusan kn-affil= en-keyword=Toloese kn-keyword=Toloese en-keyword=far infrared ray kn-keyword=far infrared ray en-keyword=nitric oxide kn-keyword=nitric oxide END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=13203 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Amyloid-forming property of the N-terminal 1?70 residues of human apolipoprotein A-IV en-subtitle= kn-subtitle= en-abstract= kn-abstract=Apolipoprotein A-IV (apoA-IV), the largest member of the exchangeable apolipoprotein family, is a common constituent of amyloid deposits in renal and cardiac amyloidosis. In this study, we characterized the aggregation propensity of the apoA-IV N-terminal fragment to form amyloid fibrils using a variety of biophysical techniques. Thioflavin T fluorescence assay, circular dichroism measurement, and microscopic observations revealed that the N-terminal 1?70 amino acid fragment of apoA-IV readily forms amyloid fibrils by a transition from a random coil to a β-sheet-rich structure. Sequence-based analysis indicated that residues 7?16 and 38?42 are the major aggregation-prone segments within the N-terminal 1?70 residues of apoA-IV. Consistent with this, deletion of these residues strongly inhibited the β-transition and fibril formation of apoA-IV 1?70. Kinetic and thermodynamic analyses of fibril formation by the apoA-IV 1?70 fragment demonstrated that primary nucleation is the dominant step in fibril formation, for which the activation energy barrier is entirely entropic. In addition, we found that the presence of heparin, a representative glycosaminoglycan, accelerated fibril formation kinetics and enhanced the yield of apoA-IV 1?70 fibrils, and the positively charged residues K58-K59 play a critical role in heparin interaction. Overall, our results suggest that the strong amyloid-forming propensity of the N-terminal fragment of apoA-IV may play a key role in amyloid deposition associated with apoA-IV amyloidosis. en-copyright= kn-copyright= en-aut-name=NambaNorihiro en-aut-sei=Namba en-aut-mei=Norihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DanjoTokiko en-aut-sei=Danjo en-aut-mei=Tokiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitagawaYuichiro en-aut-sei=Kitagawa en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaitoYoshito en-aut-sei=Naito en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhgitaTakashi en-aut-sei=Ohgita en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimanouchiToshinori en-aut-sei=Shimanouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoHiroyuki en-aut-sei=Saito en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Laboratory of Biophysical Chemistry, Kyoto Pharmaceutical University kn-affil= affil-num=2 en-affil=Laboratory of Biophysical Chemistry, Kyoto Pharmaceutical University kn-affil= affil-num=3 en-affil=Laboratory of Biophysical Chemistry, Kyoto Pharmaceutical University kn-affil= affil-num=4 en-affil=Laboratory of Biophysical Chemistry, Kyoto Pharmaceutical University kn-affil= affil-num=5 en-affil=Center for Instrumental Analysis, Kyoto Pharmaceutical University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Laboratory of Biophysical Chemistry, Kyoto Pharmaceutical University kn-affil= en-keyword=Apolipoprotein A-IV kn-keyword=Apolipoprotein A-IV en-keyword=Aggregation kn-keyword=Aggregation en-keyword=Amyloid fibril kn-keyword=Amyloid fibril en-keyword=Heparin kn-keyword=Heparin END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=1680076 end-page= 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=Prolonged TNF-α stimulation induces a PD-1?associated exhaustion-like phenotype in mesenchymal stromal cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mesenchymal stromal cells (MSCs) have emerged as promising therapeutic agents for inflammatory diseases because of their potent immunomodulatory properties. Although acute inflammation transiently enhances MSC functionality, the impact of chronic inflammatory exposure remains poorly defined. In this study, we investigated the effects of sustained TNF-α stimulation and indirect co-culture with M1 macrophages on MSC behavior. Comprehensive gene expression profiling was performed to assess the changes in immunoregulatory, apoptotic, and metabolic pathways. To determine functional reversibility, we also evaluated MSCs following the withdrawal of TNF-α. Short-term exposure led to upregulation of Tgf-β, Il-10, and Fasl, whereas prolonged stimulation suppressed these genes and significantly increased the expression of immune checkpoint genes Pd-1 and Ctla-4, indicative of an exhaustion-like phenotype. This phenotypic shift was associated with sustained NF-κB activation, upregulation of Stat3 and Ap-1, suppression of mTORC1/2 components, decreased Pd-l1 expression, and increased Pd-1 expression, raising the possibility that PD-1 upregulation is associated with MSC dysfunction under chronic inflammatory stress. These findings revealed that prolonged stimulation (48 h) induces an exhaustion-like dysfunction state in MSCs, characterized by checkpoint activation, transcriptional repression, and metabolic dysfunction. PD-1 may serve as a biomarker associated with inflammation-induced MSC impairment. en-copyright= kn-copyright= en-aut-name=MatsunagaNaoya en-aut-sei=Matsunaga en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkiyamaKentaro en-aut-sei=Akiyama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MunAung Ye en-aut-sei=Mun en-aut-mei=Aung Ye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZouTinling en-aut-sei=Zou en-aut-mei=Tinling kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItoKazuki en-aut-sei=Ito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TagashiraRuji en-aut-sei=Tagashira en-aut-mei=Ruji 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= 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 Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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= en-keyword=immune checkpoint kn-keyword=immune checkpoint en-keyword=immunoregulatory dysfunction kn-keyword=immunoregulatory dysfunction en-keyword=mesenchymal stromal cells (MSCs) kn-keyword=mesenchymal stromal cells (MSCs) en-keyword=prolonged inflammatory stimulation kn-keyword=prolonged inflammatory stimulation en-keyword=TNF-α (tumor necrosis factor-alpha) kn-keyword=TNF-α (tumor necrosis factor-alpha) 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=20260625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of Critical Amino Acid Residues Required for the Polar Localization of a Rice Manganese Transporter en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice has developed an efficient system for manganese (Mn) uptake, mediated by two distinct transporters, OsNramp5 and OsMTP9. These transporters exhibit polar localization at the root exodermis and endodermis; however, the mechanisms underlying their polar localization and their role in Mn uptake remain unclear. Here, we identified key amino acid residues critical for the polar localization of OsNramp5 at the distal side. Through analysis of chimeric proteins between OsNramp5 and its non-polar homologues, we found that the C-terminal cytosolic region of OsNramp5 is essential for its polar localization. Site-directed mutagenesis further revealed that aspartate 500 and four valine residues at positions 494, 495, 498 and 506 are crucial for polarity. Substitution of these valine residues with isoleucine, leucine, phenylalanine, or threonine partially or fully maintained polar localization, whereas substitution with alanine, serine, or asparagine resulted in loss of polarity. These findings suggest that β-branching and high hydrophobicity of amino acid side chains are likely required for OsNramp5 polarity. Furthermore, we found that adaptor protein 2-dependent clathrin-mediated endocytosis is not involved in the polar localization of OsNramp5. Finally, we provided experimental evidence showing the significant role of OsNramp5 polarity in efficient Mn uptake in rice; plants expressing non-polarly localized OsNramp5 exhibited reduced Mn uptake compared to those with polarly localized OsNramp5. In addition, we found that cadmium accumulation in shoots could be reduced by manipulating OsNramp5 polarity in combination with its overexpression, without a growth penalty. en-copyright= kn-copyright= en-aut-name=KonishiNoriyuki en-aut-sei=Konishi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= en-keyword=amino acid residue kn-keyword=amino acid residue en-keyword=clathrin-mediated endocytosis kn-keyword=clathrin-mediated endocytosis en-keyword=Mn kn-keyword=Mn en-keyword=OsNramp5 kn-keyword=OsNramp5 en-keyword=polar localization kn-keyword=polar localization en-keyword=rice kn-keyword=rice en-keyword=root kn-keyword=root en-keyword=transporter kn-keyword=transporter END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=180 end-page=186 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and Safety of Three Janus Kinase Inhibitors in Ulcerative Colitis Patients over and under 65 Years of Age: A Real-World Comparative Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: It remains unclear whether Janus kinase (JAK) inhibitors differ in efficacy and safety between elderly and non-elderly patients with ulcerative colitis. Methods: We retrospectively compared outcomes between patients who started a JAK inhibitor at ?65 years (elderly group) and those <65 years (non-elderly group). Results: Among 228, 215, and 159 patients treated with upadacitinib, filgotinib, and tofacitinib, we identified 14, 36, and 13 elderly patients, respectively. There were no significant differences in efficacy between elderly and non-elderly patients for any of the three JAK inhibitors. The elderly group had a 3-fold higher risk of herpes zoster infection with upadacitinib or tofacitinib compared to the non-elderly group, whereas the risk with filgotinib was less than 3% in both groups. The non-elderly group had a 3-fold higher risk of acne with upadacitinib. Conclusion: Adverse event risks with JAK inhibitors should be considered by age. Given the limitations of this study, including its retrospective design and small sample size, further studies with larger sample sizes are needed to validate our findings. en-copyright= kn-copyright=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: This systematic review evaluated the efficacy and safety of vaccination in patients with paediatric, adolescent, and transitional-age rheumatic diseases as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement.
Methods: An independent investigator systematically searched PubMed to identify relevant studies published by September 2022. The search results were divided into vaccines or toxoids for diphtheria, pertussis, tetanus, pneumococcus, influenza virus, hepatitis A virus, hepatitis B virus, human papillomavirus, poliovirus, measles virus, mumps virus, rubella virus, varicella zoster virus, and tuberculosis.
Results: A meta-analysis was not feasible due to the lack of randomized controlled trials with standardized patient backgrounds and conditions. Non-live vaccines are generally immunogenic and safe for patients with rheumatic diseases. In contrast, live attenuated vaccines should usually be withheld in patients on immunosuppressants, corticosteroids, biologics, or Janus kinase inhibitors. However, for necessary immunizations against measles, rubella, mumps, or varicella, live attenuated vaccines may be considered for patients receiving low-dose corticosteroids, methotrexate, or tumour necrosis factor inhibitors.
Conclusions This review highlights the significant gap in evidence for paediatric populations compared with adults, particularly concerning new biological therapies and Janus kinase inhibitors. Further evidence is needed regarding vaccination in paediatric patients with rheumatic diseases. en-copyright= kn-copyright= en-aut-name=OhnishiTakuma en-aut-sei=Ohnishi en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakiguchiHiroyuki en-aut-sei=Wakiguchi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshimoriShingo en-aut-sei=Ishimori en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItohNaohiro en-aut-sei=Itoh en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YashiroMasato en-aut-sei=Yashiro en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamazakiSusumu en-aut-sei=Yamazaki en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkafujiIkuo en-aut-sei=Okafuji en-aut-mei=Ikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhtomoYoshiyuki en-aut-sei=Ohtomo en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KobayashiIchiro en-aut-sei=Kobayashi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pediatrics, Keio University School of Medicine kn-affil= affil-num=2 en-affil=Division of General Pediatrics and Emergency Medicine, Department of Pediatrics, Oita University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Pediatrics, Kobe University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Faculty of Medical Sciences, Department of Pediatrics, University of Fukui kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics and Adolescent Medicine, Juntendo University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Pediatrics, Kobe City Medical Center General Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Juntendo University Nerima Hospital kn-affil= affil-num=9 en-affil=Center for Pediatric Allergy and Rheumatology, KKR Sapporo Medical Center kn-affil= en-keyword=Bacille Calmette?Gu?rin kn-keyword=Bacille Calmette?Gu?rin en-keyword=diphtheria, pertussis, and tetanus vaccine kn-keyword=diphtheria, pertussis, and tetanus vaccine en-keyword=hepatitis A virus vaccine kn-keyword=hepatitis A virus vaccine en-keyword=hepatitis B virus vaccine kn-keyword=hepatitis B virus vaccine en-keyword=human papillomavirus vaccine kn-keyword=human papillomavirus vaccine en-keyword=inactivated polio vaccine kn-keyword=inactivated polio vaccine en-keyword=influenza vaccine kn-keyword=influenza vaccine en-keyword=measles, mumps, and rubella vaccine kn-keyword=measles, mumps, and rubella vaccine en-keyword=pneumococcal vaccine kn-keyword=pneumococcal vaccine en-keyword=varicella zoster virus vaccine kn-keyword=varicella zoster virus vaccine END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=4 article-no= start-page=265 end-page=270 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=Transcanal Cochlear Implantation Under Endoscopic Guidance with Canal Closure in a Pediatric Patient with CHARGE Syndrome: A Case Report and Surgical Technique en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cochlear implantation (CI) in patients with CHARGE syndrome presents unique surgical challenges due to complex external, middle, and inner ear malformations.

There are few reports of this type of surgical intervention, and the present case highlights the feasibility and clinical benefits of individualized surgical planning for CI in anatomically complex patients. en-copyright= kn-copyright= en-aut-name=YamasakiTakuto en-aut-sei=Yamasaki en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaoiYuto en-aut-sei=Naoi en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=CHARGE syndrome kn-keyword=CHARGE syndrome en-keyword=cochlear implantation kn-keyword=cochlear implantation en-keyword=transcanal approach kn-keyword=transcanal approach en-keyword=temporal bone anomaly kn-keyword=temporal bone anomaly en-keyword=pediatric otologic surgery kn-keyword=pediatric otologic surgery END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=4 article-no= start-page=259 end-page=264 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=Spinous Process Plate Fixation Alone for an AO Spine Osteoporotic Fracture (OF) 5 Diffuse Idiopathic Skeletal Hyperostosis (DISH)-Associated Thoracolumbar Fracture in a Nonagenarian en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diffuse idiopathic skeletal hyperostosis (DISH) predisposes the spine to highly unstable fractures because of long lever-arm biomechanics. Unstable injuries, including AO Spine Osteoporotic Fracture (OF) type 5, are typically treated with long-segment posterior instrumentation; however, pedicle-screw fixation may be infeasible in very elderly patients with severe osteoporosis, critically narrow pedicles, and/or significant comorbidities. A 93-year-old Japanese woman presented with severe back pain without apparent trauma. Computed tomography (CT) revealed a T12 fracture with DISH, classified as OF5. The pedicles were critically narrow (3.7-4.1 mm), and dual-energy X-ray absorptiometry confirmed severe osteoporosis. Because conventional pedicle-screw fixation was considered technically unsafe and excessively invasive, limited posterior stabilization was performed using a single spinous process plate spanning T10-L1. The operative time was 48 min and the estimated blood loss was 10 ml. Immediate postoperative CT confirmed appropriate implant positioning and maintained alignment. At the 1-year follow-up, CT demonstrated solid bony union with preserved alignment and no implant failure; the patient had remained pain-free and ambulatory. This case demonstrates that spinous process-plate fixation can be a minimally invasive salvage option for carefully selected very-elderly patients with DISH when pedicle-screw instrumentation is not feasible. en-copyright= kn-copyright= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YunokiMasatoshi en-aut-sei=Yunoki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeuchiSaori en-aut-sei=Takeuchi en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirashitaKoji en-aut-sei=Hirashita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kagawa Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Kagawa Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Kagawa Rosai Hospital kn-affil= en-keyword=DISH kn-keyword=DISH en-keyword=vertebral fracture kn-keyword=vertebral fracture en-keyword=osteoporosis kn-keyword=osteoporosis en-keyword=spinous process plate kn-keyword=spinous process plate END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=4 article-no= start-page=241 end-page=246 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=Video-Assisted Thoracoscopic Resection of an Upper Mediastinal Ectopic Parathyroid Adenoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary hyperparathyroidism (pHPT) is typically caused by a parathyroid adenoma, although some cases arise from ectopic glands. Accurate preoperative localization is essential for guiding surgical strategy, particularly for mediastinal lesions. We report successful video-assisted thoracoscopic surgery (VATS) for an upper mediastinal parathyroid adenoma. A 68-year-old woman was referred for hypercalcemia during evaluation for recurrent ureteral stones. Laboratory tests revealed elevated serum calcium (13.2 mg/dl) and intact parathyroid hormone (iPTH) levels (266 pg/ml). Contrast-enhanced computed tomography, magnetic resonance imaging, and 99mTc-methoxyisobutylisonitrile scintigraphy identified a 20-mm mass adjacent to the right esophageal wall. VATS was performed due to the tumor’s mediastinal location. The lesion was resected with intraoperative nerve monitoring (IONM) to avoid recurrent laryngeal nerve damage. Postoperatively, iPTH and calcium levels rapidly normalized. Transient hypocalcemia and mild hoarseness occurred but resolved with calcium supplementation and conservative management. Pathological examination confirmed a parathyroid adenoma without malignancy. VATS offers a safe and minimally invasive approach for upper mediastinal parathyroid adenomas. IONM and vigilant calcium management are crucial for minimizing these complications. This case highlights the importance of comprehensive imaging, surgical planning, and postoperative care in managing upper mediastinal pHPT. en-copyright= kn-copyright= en-aut-name=HasegawaYuta en-aut-sei=Hasegawa en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujimotoHironori en-aut-sei=Tsujimoto en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UehataNaoyuki en-aut-sei=Uehata en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KariyaRisa en-aut-sei=Kariya en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IdeAsuma en-aut-sei=Ide en-aut-mei=Asuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiTakafumi en-aut-sei=Suzuki en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujishimaSeiichiro en-aut-sei=Fujishima en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KouzuKeita en-aut-sei=Kouzu en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YaguchiYoshihisa en-aut-sei=Yaguchi en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyaiKosuke en-aut-sei=Miyai en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KuriharaAyumu en-aut-sei=Kurihara en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OgataSho en-aut-sei=Ogata en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsukumaSusumu en-aut-sei=Matsukuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=UenoHideki en-aut-sei=Ueno en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= affil-num=10 en-affil=Department of Laboratory Medicine, National Defense Medical College Hospital kn-affil= affil-num=11 en-affil=Department of Laboratory Medicine, National Defense Medical College Hospital kn-affil= affil-num=12 en-affil=Department of Laboratory Medicine, National Defense Medical College Hospital kn-affil= affil-num=13 en-affil=Department of Laboratory Medicine, National Defense Medical College Hospital kn-affil= affil-num=14 en-affil=Department of Surgery, National Defense Medical College Hospital kn-affil= en-keyword=primary hyperparathyroidism kn-keyword=primary hyperparathyroidism en-keyword=parathyroid neoplasm kn-keyword=parathyroid neoplasm en-keyword=ectopic tissue kn-keyword=ectopic tissue en-keyword=video-assisted thoracoscopic surgery kn-keyword=video-assisted thoracoscopic surgery END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=4 article-no= start-page=233 end-page=240 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=Regional Prevalence of Carbapenemase-Producing Enterobacterales and Extended-Spectrum Beta-Lactamase-Producing Enterobacterales in Okayama and Neighboring Prefectures, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Carbapenemase-producing Enterobacterales (CPE) and extended-spectrum β-lactamase (ESBL)-producing Enterobacterales (ESBL-E) are representative antimicrobial-resistant pathogens. We investigated the prevalence of CPE and ESBL-E in Okayama, Japan to clarify their current epidemiology and potential clinical burden. Active surveillance for CPE and ESBL-E was performed first, using stool samples submitted to the Okayama Medical Laboratory (Japan) in the years 2024-2025. Screening was performed using a selective agar (CHROMagar mSuper CARBA/ESBL). Phenotypic identification was conducted with the use of a modified carbapenem inactivation method and double-disk phenotypic confirmatory tests. Clinical information including patient age, sex, sampling date, and hospital address were collected, and the data were analyzed according to specimen origin (hospitals, clinics, and health checkups). A total of 2,000 stool samples were screened, of which two CPE isolates (0.1%) and 285 ESBL-E isolates (14.3%) were identified. By specimen origin, the ESBL-E positivity rate was significantly higher in hospitals (17.4%) than in clinics (11.8%). By age category, the late elderly (> 75 years) exhibited the highest ESBL-E positivity rate (22.6%) compared to other age groups. In the clinics and health checkups, infants (0 years) demonstrated high ESBL-E positivity rates (18.2% and 14.3%, respectively). Escherichia coli was the most common ESBL-E organism in the hospitals (77.2%), clinics (88.8%), and health checkups (87.5%). Our active screening demonstrated that the prevalences of CPE and ESBL-E were within the reported ranges; however, in this era of increasing internationalization, continuous surveillance of these notifiable pathogens is warranted. en-copyright= kn-copyright= en-aut-name=OgawaSakura en-aut-sei=Ogawa en-aut-mei=Sakura 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=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NambaSachie en-aut-sei=Namba en-aut-mei=Sachie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirotaChiyoko en-aut-sei=Hirota en-aut-mei=Chiyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishiueTomoyoshi en-aut-sei=Kishiue en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbaraShohei en-aut-sei=Ibara en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoTakayuki en-aut-sei=Kondo en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FukudaGenshi en-aut-sei=Fukuda en-aut-mei=Genshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Laboratory Testing, Okayama Medical Laboratory Center kn-affil= affil-num=5 en-affil=Department of Laboratory Testing, Okayama Medical Laboratory Center kn-affil= affil-num=6 en-affil=Department of Laboratory Testing, Okayama Medical Laboratory Center kn-affil= affil-num=7 en-affil=Department of Laboratory Testing, Okayama Medical Laboratory Center kn-affil= affil-num=8 en-affil=Department of Laboratory Testing, Okayama Medical Laboratory Center kn-affil= affil-num=9 en-affil=Department of Sales Promotion, Okayama Medical Laboratory Center kn-affil= affil-num=10 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=12 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=13 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Infectious Diseases, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=carbapenem-resistant Enterobacteriaceae kn-keyword=carbapenem-resistant Enterobacteriaceae en-keyword=extended-spectrum β-lactamase kn-keyword=extended-spectrum β-lactamase en-keyword=infection prevention and control kn-keyword=infection prevention and control en-keyword=Okayama Medical Laboratory kn-keyword=Okayama Medical Laboratory END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=4 article-no= start-page=227 end-page=231 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=The Impact of Migraine on Cerebral Artery Dissection en-subtitle= kn-subtitle= en-abstract= kn-abstract=The impact of migraines as a risk factor for cervicocerebral artery dissection was retrospectively investigated in patients who had a cervicocerebral artery dissection. We first evaluated the patients’ medical records and history of migraine and then calculated the proportion of patients with migraine as well as the relevant vascular risk factors. The prevalence of migraine with respect to the location of the cervicocerebral artery dissection was also identified. Sixty-two patients (37 men, 25 women) had both a cerebral artery dissection and a record of migraine. Among them, 93.5% presented with an isolated headache, and 6.5% presented with a related stroke. Regarding the locations of the artery dissection, 56 (90.3%) were in the intracranial vertebral artery (VA), three (4.8%) were in the internal carotid artery, and one case each (1.6%) was in an anterior cerebral artery, basilar artery (BA), and both the VA and BA. Among the patients with VA dissection, 42 (73.7%) presented with migraines. Among the four patients with dissection of an artery of anterior circulation, only one (25%) had a migraine history. The frequency of migraines tended to be higher in the patients with VA dissection compared to those with a dissection of arteries of anterior circulation. These data suggest that (i) migraine is a potent risk factor for cerebral artery dissection, especially intracranial VA dissection, and (ii) the intracranial VA may be more susceptible to dissection compared to arteries of anterior circulation. en-copyright= kn-copyright= en-aut-name=KashiharaKenichi en-aut-sei=Kashihara en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamaguchiToshikazu en-aut-sei=Hamaguchi en-aut-mei=Toshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakedaYasuko en-aut-sei=Takeda en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama Neurology Clinic kn-affil= affil-num=2 en-affil=Department of Neurology, Okayama Kyokuto Hospital kn-affil= affil-num=3 en-affil=Okayama Neurology Clinic kn-affil= en-keyword=cervicocerebral artery dissection kn-keyword=cervicocerebral artery dissection en-keyword=isolated headache kn-keyword=isolated headache en-keyword=migraine kn-keyword=migraine en-keyword=risk factor kn-keyword=risk factor en-keyword=vertebral artery kn-keyword=vertebral artery END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=1 article-no= start-page=552 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260810 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preoperative membranous urethral length predicts quality-of-life recovery and urinary incontinence after holmium enucleation of the prostate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Holmium laser enucleation of the prostate (HoLEP) relieves bladder outlet obstruction, but postoperative quality-of-life (QOL) recovery and stress urinary incontinence (SUI) differ among patients. We evaluated whether preoperative membranous urethral length (MUL) on MRI predicts QOL recovery and SUI after HoLEP, independent of clinical and surgical factors.
Methods This single-center retrospective study included 135 patients with preoperative MRI. MUL was measured on sagittal T2-weighted images. The primary outcome was 6-month International Prostate Symptom Score (IPSS) -QOL ? 1. SUI was defined as the use of ?1 pad per day at 6 months. IPSS-QOL changes were analyzed with generalized estimating equations. For 6-month QOL recovery and SUI, logistic regression was adjusted for age, enucleated weight, prostate volume, baseline QOL, and surgeon. We evaluated thickness of posterior wall of membranous urethral sphincter (TPWMUS), membranous urethral volume (MUV), and a short-MUL/thin-TPWMUS phenotype.
Results The 6-month IPSS-QOL ? 1 rate was 40.0%; SUI occurred in 19/135 patients (14.1%). Longer MUL was linked to better QOL recovery at every time point (p ? 0.015) and independently predicted both 6-month QOL recovery (adjusted odds ratio [aOR] 1.35, 95% CI 1.14?1.61) and lower SUI risk (odds ratio [OR] 0.76, 0.61?0.93), remaining significant after adjustment. Adding MUL improved prediction (AUC for SUI 0.588→0.704; for QOL 0.716→0.760). Across MUL tertiles, QOL recovery rose from 13.9% to 56.1% ,and SUI fell from 20.0% to 2.2%. Short MUL/thin-TPWMUS showed higher SUI and poorer QOL recovery.
Conclusions Preoperative MUL on MRI independently predicted QOL recovery and continence after HoLEP. en-copyright= kn-copyright= en-aut-name=NagasakiNaoya en-aut-sei=Nagasaki en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuboiIchiro en-aut-sei=Tsuboi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeTomofumi en-aut-sei=Watanabe en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanemotoShin en-aut-sei=Kanemoto en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WatanabeToyohiko en-aut-sei=Watanabe en-aut-mei=Toyohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Urology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Urology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Holmium laser enucleation of the prostate kn-keyword=Holmium laser enucleation of the prostate en-keyword=Membranous urethral length kn-keyword=Membranous urethral length en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Stress urinary incontinence kn-keyword=Stress urinary incontinence en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Benign prostatic hyperplasia kn-keyword=Benign prostatic hyperplasia END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=7 article-no= start-page=e72982 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Biologically Dominant Trophoblastic Component Guiding Neoadjuvant EMA/CO in Endometrial Carcinoma: A Clinical Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endometrial carcinoma with choriocarcinomatous components (ECCC) is a rare and aggressive malignancy for which optimal management remains undefined. We report a case illustrating how preoperative identification of a biologically dominant trophoblastic component can guide treatment sequencing and achieve durable remission. A 61-year-old postmenopausal woman presented with abnormal uterine bleeding. Endometrial biopsy revealed a mixed tumor composed predominantly of choriocarcinomatous elements with a minor grade 1 endometrioid carcinoma component. Despite only superficial myometrial invasion, imaging demonstrated multiple pulmonary nodules, and serum human chorionic gonadotropin (hCG) was markedly elevated (46,538?mIU/mL). This clinicopathological incongruity suggested that the trophoblastic component, rather than the low-grade endometrioid carcinoma, was driving disease progression. Neoadjuvant EMA/CO chemotherapy was therefore prioritized to achieve rapid systemic control. After six cycles, serum hCG normalized and pulmonary lesions completely resolved. The patient subsequently underwent total hysterectomy and bilateral salpingo-oophorectomy, which revealed no residual choriocarcinoma. She remains disease-free more than two years after completion of treatment. This case highlights the importance of recognizing clinicopathological incongruity and identifying the biologically dominant tumor component when determining treatment sequencing in rare mixed

radical treatments compromise reproductive potential. This study aims to evaluate the feasibility, oncological safety, and reproductive outcomes of fertility-sparing treatment involving neoadjuvant chemotherapy followed by cervical conization and laparoscopic pelvic lymphadenectomy. This single-center, prospective, open-label, single-arm, Phase II interventional study will assess patients with FIGO stage IB2?IB3 cervical cancer (FIGO stage 2018) desiring fertility preservation. Eligible patients will receive three cycles of dose-dense paclitaxel and carboplatin (dd-TC), followed by conization and laparoscopic lymphadenectomy. The primary endpoint is successful uterine preservation. Patients requiring concurrent chemoradiotherapy due to inadequate treatment response will not be considered successful. Secondary endpoints include 2-year recurrence-free survival (RFS), overall survival (OS), quality of life assessments, menstrual and ovulatory resumption, pregnancy, live birth, miscarriage, and preterm birth. Adverse events will be graded according to CTCAE v5.0. en-copyright= kn-copyright= en-aut-name=TaniokaMomoko en-aut-sei=Tanioka en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaoShoji en-aut-sei=Nagao en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IdaNaoyuki en-aut-sei=Ida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaYui en-aut-sei=Tanaka en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujikawaAtsushi en-aut-sei=Fujikawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ImataniRyoko en-aut-sei=Imatani en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniYoshinori en-aut-sei=Tani en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiharaHanako en-aut-sei=Sugihara en-aut-mei=Hanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkamotoKazuhiro en-aut-sei=Okamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuokaHirofumi en-aut-sei=Matsuoka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HaragaJunko en-aut-sei=Haraga en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Obstetrics and Gynecology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=8 article-no= start-page=e0356180 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260813 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Study protocol: Effect of inulin supplementation on gut microbiota in patients with oral lichen planus ? A double-blind, randomised, placebo-controlled parallel-group trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral lichen planus is a chronic inflammatory disease of the oral mucosa characterised by immune dysregulation, but its pathogenesis remains incompletely understood and no curative treatment has been established. Our previous work showed that patients with oral lichen planus exhibit gut dysbiosis, including reduced microbial diversity and depletion of butyrate-producing bacteria. Because butyrate promotes regulatory T-cell differentiation and supports immune homeostasis, targeting this dysbiosis may represent a microbiota-directed approach for immune modulation in oral lichen planus. This study aims to investigate the effects of inulin supplementation on the gut microbiota and related immune markers in patients with oral lichen planus. This multicentre, double-blind, randomised, placebo-controlled parallel-group trial will enrol 80 patients with oral lichen planus. Participants will be randomly assigned in a 1:1 ratio to receive either inulin (8 g/day) or a maltose placebo for 4 weeks, in addition to standard care. The primary outcome is the change in the relative abundance of prespecified butyrate-producing gut bacteria from baseline to the end of intervention at Week 6. Secondary outcomes include changes in gut microbiota diversity, salivary microbiota composition, faecal short-chain fatty acid concentrations, peripheral blood regulatory T-cell counts, blood test parameters, and clinical symptoms of oral lichen planus. Analyses will follow the intention-to-treat principle, and between-group differences will be assessed using appropriate statistical methods. This trial is designed to evaluate, in a randomised placebo-controlled setting, whether a microbiota-directed intervention can modify gut microbial profiles and related immune markers in patients with oral lichen planus. The findings are expected to clarify whether inulin supplementation can modify gut microbial profiles and related immunological markers in patients with oral lichen planus.

We, therefore, assess the diversity and relative abundance of hymenopteran insects in cotton fields from five locations of Bangladesh using five types of traps (Malaise, Yellow Pan, Fluorescent Yellow Pan, Pitfall, and Sweep Net). Analysis of samples revealed presence of diverse type of hymenopteran insects from the studied locations, with a total of 1642 insects collected, representing 28 morphospecies and 16 families of the Hymenoptera. Formicidae, Braconidae, Diapridae, Figitidae, Ichneumonidae, Scelionidae constitutes the major families comprises of 36.37, 25.09, 5.36, 5.24, 5.18 and 4.93% of the populations respectively. Among the locations, cotton fields of Rangpur showed the highest species richness, diversity indices (Simpson, and Shannon values), while cotton fields located at Jashore had the lowest. Yellow and fluorescent pan traps captured insects from nearly all families, indicating broad sampling effectiveness. Malaise traps also sampled a wide range of families except for low captures of Formicidae. Pitfall traps primarily targeted Formicidae, consistent with their ground-dwelling hymenopterans. Sweep nets captured fewer families, reflecting a more selective sampling role. Among functional guilds, parasitoids were the most abundant, followed by predators, pollinators, and herbivores of hymenopteran insects. Overall, the hymenopteran community in cotton agroecosystems from Bangladesh was dominated by parasitoid families, indicating strong potential for natural biological control. Leveraging this natural enemy dominance could significantly reduce dependence on chemical insecticides. These findings support the integration of parasitoid conservation strategies into national Integrated Pest Management (IPM) programs and landscape-level pest management policies. en-copyright= kn-copyright= en-aut-name=RahmanMd Mizanur en-aut-sei=Rahman en-aut-mei=Md Mizanur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayakawaTohru en-aut-sei=Hayakawa en-aut-mei=Tohru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HowladerMohammad Tofazzal Hossain en-aut-sei=Howlader en-aut-mei=Mohammad Tofazzal Hossain kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Insect Biotechnology and Biopesticide Laboratory, Department of Entomology, Bangladesh Agricultural University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Insect Biotechnology and Biopesticide Laboratory, Department of Entomology, Bangladesh Agricultural University kn-affil= en-keyword=Biodiversity kn-keyword=Biodiversity en-keyword=Hymenoptera kn-keyword=Hymenoptera en-keyword=Bangladesh kn-keyword=Bangladesh en-keyword=Baseline kn-keyword=Baseline en-keyword=Conservation kn-keyword=Conservation END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=4 article-no= start-page=538 end-page=549 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhancement of antioxidant function in various organs in mice using combined thermal and radon inhalation treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Enhancing antioxidant function is a key strategy for preventing and treating oxidative stress-related diseases. Radon inhalation and thermal treatment (TT) increase the levels of antioxidant enzymes, such as superoxide dismutase (SOD). The positive effects of this combination on pain-related diseases have been reported; however, few studies have elucidated the underlying mechanisms. In this study, we examined the enhancement of antioxidant function in various organs of mice subjected to combined TT and radon inhalation. The mice were placed in an incubator once daily for 40 min at 38.5 ± 0.5°C and treated for 1, 3 and 7 days. The mice then inhaled radon at a concentration of 2000 Bq/m3 for 24 h. The characteristic changes in antioxidant function following combined TT and radon inhalation could be categorized into four groups: (i) increased antioxidant function in the brain and colon; (ii) increased or decreased antioxidant function, as observed in the kidney; (iii) decreased antioxidant function, such as in the lungs and (iv) no changes, such as in the small intestine, spleen, pancreas, heart, liver and stomach. Additionally, SOD may be the antioxidant enzyme most sensitive to combined TT and radon treatment. Collectively, the combined treatment may be the most effective in activating antioxidative functions in the brain and colon. This study provides new insights into the effects of combined TT and radon inhalation. en-copyright= kn-copyright= en-aut-name=MiyanagaShogo en-aut-sei=Miyanaga en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotoShuna en-aut-sei=Goto en-aut-mei=Shuna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaganoMitsuki en-aut-sei=Nagano en-aut-mei=Mitsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanoKotaro en-aut-sei=Tano en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=5 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=9 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=10 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=radon kn-keyword=radon en-keyword=thermal treatment kn-keyword=thermal treatment en-keyword=antioxidant function kn-keyword=antioxidant function en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=e77709 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association Between Dinner-to-Bed Time and Gastroesophageal Reflux-Related Diseases in Children en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Gastroesophageal reflux disease (GERD) is characterized by esophageal mucosal injury due to the reflux of gastroduodenal contents. Typical symptoms include heartburn and acid regurgitation. In addition, gastroesophageal reflux (GER) can influence conditions such as otitis media, rhinitis, and asthma. This study aimed to examine the association between dinner-to-bed time and GER-related diseases, such as otitis media, allergic rhinitis, and asthma.
Methods: This was a longitudinal cohort study using secondary data. Data were collected from a large-scale birth cohort study conducted in Japan including babies born in 2001 and 2010. Dinner-to-bed time was categorized as “longer dinner-to-bed time" (>120 minutes), “shorter dinner-to-bed time" (?120 minutes or less), and “irregular dinner-to-bed time.” Modified Poisson regression with robust variance was used to estimate risk ratios (RRs).
Results: A total of 60,392 children were included in this study. Children with shorter dinner-to-bed time had a higher risk of asthma (adjusted RR (aRR)?=?1.10; 95% confidence interval (CI), 1.03-1.18) than those with longer dinner-to-bed time. However, no significant association was observed between shorter dinner-to-bed time and otitis media or allergic rhinitis. Furthermore, supplementary analyses revealed that the risk of asthma was significantly higher in children born in 2001 (aRR?=?1.13; 95% CI, 1.04-1.22).
Conclusion: This study showed that dinner-to-bed time within 120 minutes after dinner increases the risk of developing asthma. This underscores the importance of considering lifestyle modifications, as certain pediatric asthma cases may be influenced by behaviors that promote GER. en-copyright= kn-copyright= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke 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=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Otolaryngology - Head and Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Otolaryngology- Head and Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=acute otitis media kn-keyword=acute otitis media en-keyword=allergic rhinitis (ar) kn-keyword=allergic rhinitis (ar) en-keyword=gastroesophageal reflux symptoms kn-keyword=gastroesophageal reflux symptoms en-keyword=pediatric asthma kn-keyword=pediatric asthma en-keyword=public health kn-keyword=public health END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=e78399 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Rare Course of Chiari Malformation With Large Syringomyelia Presenting at 54 Years Old en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chiari malformation type 1 (CM1) is considered a congenital condition. The symptoms include severe headache, hypalgesia, and loss of temperature sensation. It constitutes a significant burden among children and young adults. The onset of symptoms of CM1 is more commonly observed in relatively young children and is very rare in those over 50 years old. This study aims to present a rare surgical case of CM1 associated with a large syringomyelia in a 54-year-old man.
A 54-year-old man with low back pain was introduced to our department. He had slight hyperreflexia of the extremities, slight muscle weakness in both legs, and numbness in the right leg (3/10). He also had urinary and bowel incontinence and spastic gait. Cervical magnetic resonance imaging (MRI) showed CM1 with large syringomyelia extending from C1 to T11. The cervical canal was widened because of a long history of spinal cord expansion.
The patient was successfully treated surgically by foramen magnum decompression and syringosubarachnoid shunting under the guidance of O-arm navigation. The muscle weakness and sensory function recovered almost entirely on the one-year follow-up. The patient's cervical Japanese Orthopedic Association (JOA) score had improved from 11/17 to 16/17.
Gradually enlarging syringomyelia with slight CM1 is rare, but surgeons should consider this condition's possibility. Foramen magnum decompression achieves good results even in cases with a long history of syringomyelia. This new navigation technique provides an excellent result for a large syringomyelia with CM1. en-copyright= kn-copyright= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SharmaSneha en-aut-sei=Sharma en-aut-mei=Sneha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GoriKushal H en-aut-sei=Gori en-aut-mei=Kushal H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShohidullahMd en-aut-sei=Shohidullah en-aut-mei=Md kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Orthopedics, North Delhi Municipal Corporation (DMC) Medical College kn-affil= affil-num=3 en-affil=Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=chiari malformation kn-keyword=chiari malformation en-keyword=foramen magnum decompression kn-keyword=foramen magnum decompression en-keyword=large syringomyelia kn-keyword=large syringomyelia en-keyword=navigation system kn-keyword=navigation system en-keyword=syringosubarachnoid shunting kn-keyword=syringosubarachnoid shunting END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=10 article-no= start-page=e71325 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vonoprazan-Associated Mucosal Redness: A Report of Two Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vonoprazan, a potassium-competitive acid blocker, is effective at treating acid-related gastrointestinal disorders but has been linked to gastric mucosal redness, a novel condition.

Case 2 involved a 70-year-old man who exhibited significant erythema and atrophic gastritis after seven months of treatment. In both cases, the pathological findings included hemorrhage in the superficial mucosa, highlighting that microhemorrhage may be the corresponding pathological finding for vonoprazan-associated mucosal redness. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaNobumasa en-aut-sei=Ikeda en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Pathology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Internal Medicine, Clinic Ikeda kn-affil= en-keyword=endoscopy kn-keyword=endoscopy en-keyword=gastric mucosal redness kn-keyword=gastric mucosal redness en-keyword=microhemorrhage kn-keyword=microhemorrhage en-keyword=potassium-competitive acid blocker kn-keyword=potassium-competitive acid blocker en-keyword=vonoprazan kn-keyword=vonoprazan END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=8 article-no= start-page=e73170 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=Black Hairy Tongue in a 54‐Day‐Old Infant: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Black hairy tongue is a benign condition caused by elongation and defective desquamation of the filiform papillae, and it is uncommon in neonates and infants. We report a case in a 54-day-old girl who presented with a black lesion on the tongue dorsum. The lesion had first been noted at the 1-month medical checkup and persisted despite observation. At presentation, a localized blackish-brown lesion with accentuated filiform papillae was observed on the tongue dorsum and could not be wiped off with gauze. Oral candidiasis was considered in the differential diagnosis, but microbiological examination detected no Candida species. A clinical diagnosis of black hairy tongue was made, and the parents were instructed to gently clean the tongue dorsum with gauze and a sponge brush. The lesion resolved within 2?weeks without recurrence. Recognition of this benign entity may help avoid unnecessary treatment in infants. en-copyright= kn-copyright= en-aut-name=MasuiMasanori en-aut-sei=Masui en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoYumi en-aut-sei=Sakamoto en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=black hairy tongue kn-keyword=black hairy tongue en-keyword=case report kn-keyword=case report en-keyword=infant kn-keyword=infant en-keyword=oral hygiene kn-keyword=oral hygiene END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=88 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early-Stage Oral Squamous Cell Carcinoma in Adolescents and Young Adults Compared with Older Patients Exhibits Distinct Clinicopathological Features en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This study aimed to compare the clinicopathological features of stage I?II oral squamous cell carcinoma (OSCC) between adolescents and young adults (AYAs) and older patients, and to identify prognostic factors in AYA OSCC.
Methods Forty-eight AYA patients aged 15?39 years and 69 older patients aged???65 years with surgically treated stage I?II OSCC were retrospectively analyzed. Histological evaluation, survival analysis, immunohistochemistry for p53, p16, and MTAP, high-risk HPV RNA in situ hybridization, and fluorescence in situ hybridization for CDKN2A and MTAP were performed.
Results Compared with older patients, OSCCs in AYAs were more frequently located on the tongue (93.7% vs. 47.8%) and more often exhibited a superficial spreading growth pattern (60.4% vs. 31.8%). AYA tumors more frequently showed modified WPOI-1, high tumor budding, and abnormal p53 immunophenotypes (85.4% vs. 68.1%). AYA patients showed significantly better overall and disease-free survival than older patients. Within the AYA group, depth of invasion (DOI)?>?5 mm was associated with distant metastasis and poorer overall and disease-free survival. Postoperative lymph node metastasis occurred in 31.2% of AYAs. Univariable analysis suggested that clinical stage II, tumor thickness?>?5 mm, DOI?>?5 mm, and tumor budding scores 1?2 were associated with postoperative lymph node metastasis. Molecular status, including p53, p16/CDKN2A, and MTAP, did not provide robust prognostic stratification.
Conclusion Early-stage AYA OSCC exhibits distinct clinicopathological features. DOI was the strongest prognostic indicator, whereas clinical stage, tumor thickness, and tumor budding may provide additional prognostic information regarding the risk of late nodal metastasis. en-copyright= kn-copyright= en-aut-name=OnoSawako en-aut-sei=Ono en-aut-mei=Sawako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiroseKatsutoshi en-aut-sei=Hirose en-aut-mei=Katsutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeTatsuya en-aut-sei=Abe en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasuiMasanori en-aut-sei=Masui en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IkedaChihoko en-aut-sei=Ikeda en-aut-mei=Chihoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IsomuraMadoka en-aut-sei=Isomura en-aut-mei=Madoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TachibanaYuri en-aut-sei=Tachibana en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OnoJunya en-aut-sei=Ono en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShimadaKatsumitsu en-aut-sei=Shimada en-aut-mei=Katsumitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Pathology, Osaka University Graduate School of Dentistry kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Oral Pathology, Faculty of Dentistry & Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology, Osaka Dental University kn-affil= affil-num=8 en-affil=Department of Diagnostic Pathology, School of Medicine, Fujita Health University kn-affil= affil-num=9 en-affil=Department of Pathology Informatics, Nagasaki University Graduate School of Biomedical Sciences, Nagasaki University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Pathology, The Nippon Dental University School of Life Dentistry at Niigata kn-affil= affil-num=11 en-affil=Department of Clinical Pathophysiology, School of Dentistry, Matsumoto Dental University kn-affil= affil-num=12 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Squamous cell carcinoma of head and neck kn-keyword=Squamous cell carcinoma of head and neck en-keyword=Mouth neoplasms kn-keyword=Mouth neoplasms en-keyword=Adolescent kn-keyword=Adolescent en-keyword=Young adult kn-keyword=Young adult en-keyword=Prognosis kn-keyword=Prognosis en-keyword=Immunohistochemistry kn-keyword=Immunohistochemistry en-keyword=Tumor suppressor protein p53 kn-keyword=Tumor suppressor protein p53 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e71464 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260729 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of Tris(indol-3-yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two-Step Construction of π-Conjugated Systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tris(indol-3-yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. This is the first CO2 fixation reaction forming the aliphatic methine (>CH─) group. The isotope-labeling experiments clearly demonstrated that the carbon and hydrogen atoms of the methine group originated from carbon dioxide and dimethylphenylsilane, respectively. The mechanism for the multicomponent cascade reaction was elucidated by DFT calculations. One of the CO2-derived products, tris(4-bromo-1-methylindol-3-yl)methane, underwent palladium-catalyzed intramolecular cascade reactions for the selective formation of two novel polycyclic heteroaromatic compounds, where the methine C(sp3) atom originating from CO2 was converted into aromatic C(sp2) atoms. One is formally produced via double direct C─H arylation, Wacker-type oxidation, dehydrogenation, and debromination, while the other seems to be produced via the intramolecular homocoupling of aryl bromide, direct C─H arylation, Wacker-type oxidation, and dehydrogenation. Both of them are new intramolecular cascade reactions that are useful for the short-step construction of nitrogen-doped nanographenes. On the other hand, one of the CO2-derived products, tris(1-pentylindol-3-yl)methane, was converted into tris(1-pentylindol-3-yl)methylium methanesulfonate, which is a potential antitumor drug. This is the first derivatization of CO2 to a cationic C(sp2) center. en-copyright= kn-copyright= en-aut-name=LiSha en-aut-sei=Li en-aut-mei=Sha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaibaraSo en-aut-sei=Saibara en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiReito en-aut-sei=Yasui en-aut-mei=Reito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaishiKazuto en-aut-sei=Takaishi en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NittaNatsumi en-aut-sei=Nitta en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=boranes kn-keyword=boranes en-keyword=carbondioxidefixation kn-keyword=carbondioxidefixation en-keyword=cascadereaction kn-keyword=cascadereaction en-keyword=heteroaromatics kn-keyword=heteroaromatics en-keyword=silanes kn-keyword=silanes END start-ver=1.4 cd-journal=joma no-vol=541 cd-vols= no-issue= article-no= start-page=113868 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a novel histidine-rich glycoprotein measurement system as a biomarker for sepsis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The plasma histidine-rich glycoprotein concentration is a marker of sepsis severity. In this study, we generated selective and specific monoclonal antibodies against histidine-rich glycoprotein for use in a prototype enzyme-linked immunosorbent assay-based in vitro diagnostic system. First, we investigated the properties of monoclonal antibodies produced by 21 hybridomas that we developed using immunized mice, and we identified monoclonal antibodies 69-1A and 75-2D to be the most suitable combination for use in the sandwich enzyme-linked immunosorbent assay. Wild-type histidine-rich glycoprotein (Form-1, 75 kDa) with a proline residue at amino acid position 204 is the most common isoform of the protein in humans, followed by its variant (Form-2, 77 kDa), which has a serine residue at position 204.
The epitope mapping was examined for the HRG amino acid sequence with 69-1A and 75-2D mAbs to achieve the identification of respective specific binding domains, though the other kinds of mAbs showed considerably complex domains. The identified epitopes recognized by 69-1A and 75-2D monoclonal antibodies did not span position 204. Furthermore, immunoprecipitation-immunoblotting analysis showed that the 69-1A and 75-2D monoclonal antibodies could bind to both Form-1 and Form-2 in human plasma samples. Thus, these two new antibodies can be used to clearly detect both forms of histidine-rich glycoproteins in human plasma samples. In our analysis of clinical samples by enzyme-linked immunosorbent assays using various combinations of our newly synthesized antibodies, we found that the histidine-rich glycoprotein concentration was significantly lower in plasma samples from septic patients than in those from healthy volunteers (p < 0.01). Thus, our novel analysis system using the new antibodies is expected to be a useful tool for sepsis research, and it may be adapted as an in vitro diagnostic tool for many other kinds of diseases in the future. en-copyright= kn-copyright= en-aut-name=UchiumiTakaoki en-aut-sei=Uchiumi en-aut-mei=Takaoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueYoko en-aut-sei=Inoue en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiHiroshi en-aut-sei=Nishi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtaNorio en-aut-sei=Ota en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Diagnostic Drug Office, Shionogi & Co., Ltd. kn-affil= affil-num=2 en-affil=Department of Translational Research and Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Diagnostic Drug Office, Shionogi & Co., Ltd. kn-affil= affil-num=5 en-affil=Diagnostic Drug Office, Shionogi & Co., Ltd. kn-affil= affil-num=6 en-affil=Diagnostic Drug Office, Shionogi & Co., Ltd. kn-affil= en-keyword=Histidine-rich glycoprotein kn-keyword=Histidine-rich glycoprotein en-keyword=Sandwich enzyme-linked immunosorbent assay kn-keyword=Sandwich enzyme-linked immunosorbent assay en-keyword=In vitro diagnostics kn-keyword=In vitro diagnostics en-keyword=Sepsis kn-keyword=Sepsis en-keyword=Anti-human histidine-rich glycoprotein mouse monoclonal antibody kn-keyword=Anti-human histidine-rich glycoprotein mouse monoclonal antibody END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=7 article-no= start-page=1992 end-page=2003 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260514 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of population-approach programs promoting salt reduction and potassium intake in Japan: the Population-based Sodium/Potassium Improvement Program (PoSPIP) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Reducing sodium intake in populations is essential, but insufficient for preventing and managing high blood pressure, while the importance of increasing potassium intake is overlooked. We investigated the effects of 1-year population-approach programs (2021?2022) promoting salt reduction and potassium intake using urinalysis feedback and food environment improvement. This retrospective observational study included 7649 participants (mean age, 54.0 years; 45.3% women) from 11 municipalities and 4 workplaces. Outcomes in intensive support programs?including urinary sodium, potassium, and sodium-to-potassium (Na/K) ratio measurements with feedback, dietary promotion, and food environment improvement?were compared with standard support programs providing usual health guidance. In linear regression adjusted for demographics, lifestyle factors, and medical history, the reduction in urinary Na/K ratio was greater in the intensive support group (n?=?4064) than in the standard support group (n?=?3585) (mean difference ?0.14 [95% confidence interval, ?0.27 to ?0.01]). Although estimated potassium intake decreased in both groups, the decline was smaller in the intensive support group (mean difference 31 [12 to 51] mg/day). Estimated salt intake did not differ between the groups. The intensive support group showed greater increases in diastolic blood pressure and high-density lipoprotein cholesterol and smaller increases in blood glucose, as well as greater reductions in hemoglobin A1c and Salt Check Sheet scores. Mean differences between the groups for endpoints were not heterogeneous across intensive support program types. Our findings support the development of hypertension prevention and management strategies that promote healthier dietary behaviors and can be implemented in community and workplace settings, with broad public health applicability. en-copyright= kn-copyright= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhkuboTakayoshi en-aut-sei=Ohkubo en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuchihashiTakuya en-aut-sei=Tsuchihashi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshitaKatsushi en-aut-sei=Yoshita en-aut-mei=Katsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakemiYukari en-aut-sei=Takemi en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayabuchiHitomi en-aut-sei=Hayabuchi en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamiYukiko en-aut-sei=Okami en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KitaokaKaori en-aut-sei=Kitaoka en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaguchiKeiko en-aut-sei=Sakaguchi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HozawaAtsushi en-aut-sei=Hozawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OkamuraTomonori en-aut-sei=Okamura en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ItohHiroshi en-aut-sei=Itoh en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=RakugiHiromi en-aut-sei=Rakugi en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NodeKoichi en-aut-sei=Node en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hygiene and Public Health, Teikyo University School of Medicine kn-affil= affil-num=4 en-affil=Cardiovascular Center, Steel Memorial Yawata Hospital kn-affil= affil-num=5 en-affil=Department of Public Health, Nutrition, School of Human Life and Ecology, Osaka Metropolitan University kn-affil= affil-num=6 en-affil=Faculty of Nutrition, Kagawa Nutrition University kn-affil= affil-num=7 en-affil=Graduate School of Health and Environmental Sciences, Fukuoka Women’s University kn-affil= affil-num=8 en-affil=Gunma University Center for Food Science and Wellness kn-affil= affil-num=9 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=10 en-affil=Faculty of Nursing and Nutrition, Shukutoku University kn-affil= affil-num=11 en-affil=Division of Epidemiology, School of Public Health, Tohoku University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Preventive Medicine and Public Health, Keio University School of Medicine kn-affil= affil-num=13 en-affil=Japanese Society of Hypertension kn-affil= affil-num=14 en-affil=Japanese Society of Hypertension kn-affil= affil-num=15 en-affil=Japanese Society of Hypertension kn-affil= affil-num=16 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= en-keyword=Implemental hypertension kn-keyword=Implemental hypertension en-keyword=Sodium kn-keyword=Sodium en-keyword=Potassium kn-keyword=Potassium en-keyword=Urinalysis kn-keyword=Urinalysis en-keyword=Food environment kn-keyword=Food environment END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=14 article-no= start-page=e2026GL122472 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical Conductivity of Hydrous Ultramafic Melts With Implications for Origin of Low Velocity Layer Atop of the 410?km Seismic Discontinuity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Low-velocity layers (LVLs) above the 410-km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition-zone material rises into the upper mantle, where water solubility in nominally anhydrous minerals decreases. Interpreting coexisting high-conductivity anomalies requires constraints on the intrinsic conductivity of the melt phase at pressures just above the transition zone. We measured electrical conductivity of hydrous ultramafic melts representative of incipient melts, ranging from 6.3 to 18.6 wt% H2O at 13 GPa using impedance spectroscopy in a Kawai-type multi-anvil apparatus. Hydrous ultramafic melts are extremely conductive, and conductivity increases systematically with H2O content to values comparable to alkali-carbonate melts. The high conductivity implies that even small fractions of interconnected hydrous melt can dominate bulk mantle conductivity. Combining our measurements with geophysical conductance estimates indicates that <1 vol% melt can produce conductive layers thicker than 10 km, consistent with seismological constraints on LVL structure. en-copyright= kn-copyright= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=XieLongjian en-aut-sei=Xie en-aut-mei=Longjian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Center for High Pressure Science & Technology Advanced Research kn-affil= en-keyword=electrical conductivity kn-keyword=electrical conductivity en-keyword=water kn-keyword=water en-keyword=low velocity zone kn-keyword=low velocity zone en-keyword=silicate melt kn-keyword=silicate melt en-keyword=mantle kn-keyword=mantle END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page= 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=Carcinoma ex Pleomorphic Adenoma With an Epithelial‐Myoepithelial Carcinoma Component in the Submandibular Gland: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Carcinoma ex pleomorphic adenoma (CXPA) is an uncommon malignant salivary gland tumor arising from pleomorphic adenoma, whereas epithelial-myoepithelial carcinoma (EMC) is a rare low-grade salivary gland malignancy. CXPA with an EMC component in the submandibular gland is uncommon.
Case Report: A 65-year-old man presented with a painless, firm mass in the left submandibular region and weakness of the left lower lip. Computed tomography and magnetic resonance imaging demonstrated an irregular submandibular mass, and FDG-PET/CT showed increased uptake (maximum standardized uptake value, 9.2). Core biopsy suggested pleomorphic adenoma; however, the clinical and radiological findings strongly indicated malignancy. Incisional biopsy was therefore performed under general anesthesia, with a plan to proceed to definitive treatment if malignancy was confirmed. Intraoperative histopathological examination revealed a malignant salivary gland tumor, and tumor resection with neck dissection was completed during the same procedure. Histopathological examination showed invasive CXPA with an EMC component, accompanied by extracapsular invasion exceeding 6?mm, perineural invasion, and extension into adjacent muscle (pT3N0). Although surgical margins were negative, pulmonary metastases developed 12 months after surgery, followed by suspected pleural dissemination and spinal canal extension. The patient declined further aggressive treatment and died of the disease 48 months after surgery.
Conclusion: This case highlights the importance of integrating clinical, radiological, and pathological findings for accurate diagnosis of salivary gland tumors, particularly when biopsy results are inconsistent with clinical suspicion. en-copyright= kn-copyright= en-aut-name=YasuharaTomohiro en-aut-sei=Yasuhara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MasuiMasanori en-aut-sei=Masui en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakakuraHiroaki en-aut-sei=Takakura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataEiji en-aut-sei=Iwata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadoyaKoichi en-aut-sei=Kadoya en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UmemoriKoki en-aut-sei=Umemori en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshiokaNorie en-aut-sei=Yoshioka en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=carcinoma ex pleomorphic adenoma kn-keyword=carcinoma ex pleomorphic adenoma en-keyword=case report kn-keyword=case report en-keyword=epithelial-myoepithelial carcinoma kn-keyword=epithelial-myoepithelial carcinoma en-keyword=salivary gland neoplasm kn-keyword=salivary gland neoplasm en-keyword=submandibular gland kn-keyword=submandibular gland 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=20260717 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tripartite Interaction Between Penicillium pinophilum-Host Plants and CMV-Y: A Model for Endophyte-Mediated Viral Biocontrol en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plant-fungus-virus tripartite interactions represent complex ecological systems in which mutualistic endophytes can influence host physiology, yet the molecular basis of endophyte-mediated defence remains poorly understood. Here, we demonstrate that the endophytic fungus Penicillium pinophilum EU0013 suppresses the yellow strain of cucumber mosaic virus (CMV-Y) in Solanum lycopersicum and Nicotiana benthamiana. CMV-Y infection induced pronounced oxidative and hormonal perturbations, which were mitigated by P. pinophilum colonisation. Endophyte-associated plants exhibited early accumulation of jasmonate intermediates, consistent with the activation of jasmonate signalling. This response promoted the degradation of jasmonate-ZIM-domain proteins and release of core JA-responsive transcription factors. Virus-induced gene silencing identified MYC2 as a key regulator required for endophyte-mediated antiviral protection, with WRKY17 contributing to defence modulation. In parallel, transcriptome analysis revealed the upregulation of a Dicer-like gene, indicating enhanced engagement of RNA silencing, a primary antiviral mechanism targeting viral RNA. This coordinated activation occurred alongside significant induction of pathogenesis-related proteins, particularly PR9, and improved control of reactive oxygen species. Salicylic acid-responsive defences showed a host-modulated pattern, with PR1 induced by CMV and PR2/PR5 preferentially enhanced in endophyte-associated plants. Collectively, these findings demonstrate that P. pinophilum enhances antiviral immunity through coordinated defence integration pathways, providing a framework for endophyte-based viral disease management. en-copyright= kn-copyright= en-aut-name=IbiangSarah R. en-aut-sei=Ibiang en-aut-mei=Sarah R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GalisIvan en-aut-sei=Galis en-aut-mei=Ivan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Group of Plant-Microbe Interactions, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Group of Plant-Insect Interactions, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Group of Plant-Microbe Interactions, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Group of Plant-Microbe Interactions, Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=cucumber mosaic virus kn-keyword=cucumber mosaic virus en-keyword=endophyte‐mediated resistance kn-keyword=endophyte‐mediated resistance en-keyword=jasmonate signalling kn-keyword=jasmonate signalling en-keyword=pathogenesis‐related proteins kn-keyword=pathogenesis‐related proteins en-keyword=solanaceae kn-keyword=solanaceae en-keyword=tripartite interaction kn-keyword=tripartite interaction 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=17 cd-vols= no-issue= article-no= start-page=1875734 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Quantitative resistance to Rhizoctonia solani AG-4 develops independently in leaves and roots of Brachypodium distachyon en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rhizoctonia solani is a soil-borne phytopathogen with a broad host range, classified into multiple anastomosis groups (AGs). While the rice sheath blight pathogen AG-1 IA is well-studied, defense mechanisms against AG-4, which infects diverse monocots and dicots, remain unclear. Here, we screened 153 Brachypodium distachyon accessions for resistance to AG-4 HG-I+II using both leaf and soil inoculation assays. The accessions exhibited a quantitative resistance spectrum in both assays. Some accessions were resistant to both methods, while others showed resistance in only one, indicating that leaf and root defenses operate independently. Unlike the salicylic acid (SA)-dependent resistance observed in several accessions against AG-1 IA, AG-4 leaf resistance appears to be largely SA-independent. Among 22 resistant accessions, only eight induced the SA marker BdWRKY38, whereas twelve induced the jasmonic acid (JA) marker BdAOS. Additionally, resistance in Bd3?1 was unaffected by expression of the SA hydroxylase NahG. These results are consistent with previous findings that exogenous application of SA, JA, or ethylene fails to confer AG-4 resistance. Instead, most AG-4-resistant accessions showed common upregulation of cell wall biosynthesis-related genes following leaf infection, suggesting that cell wall fortification may contribute to defense against AG-4. These findings establish B. distachyon as a valuable model for dissecting resistance mechanisms against R. solani AG-4. en-copyright= kn-copyright= en-aut-name=FernandaRozi en-aut-sei=Fernanda en-aut-mei=Rozi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MahadevanNiranjan en-aut-sei=Mahadevan en-aut-mei=Niranjan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KohnoNatsuka en-aut-sei=Kohno en-aut-mei=Natsuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaoReiko en-aut-sei=Nagao en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=School of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=School of Agriculture, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Crop Stress Management Group, Division of Plant Molecular Regulation Research, Institute of Agrobiological Sciences, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=11 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=12 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Brachypodium distachyon kn-keyword=Brachypodium distachyon en-keyword=cell wall fortification kn-keyword=cell wall fortification en-keyword=phytohormone kn-keyword=phytohormone en-keyword=quantitative resistance kn-keyword=quantitative resistance en-keyword=Rhizoctonia solani kn-keyword=Rhizoctonia solani en-keyword=root infection kn-keyword=root infection END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=1 article-no= start-page=109 end-page=115 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safe Continuation of Apheresis during Pregnancy using the Double-Filtration Plasmapheresis Thermo Mode in a Pregnant Female with Familial Hypercholesterolemia: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Familial hypercholesterolemia (FH) is an inherited disorder characterized by elevated LDL cholesterol levels and an increased risk of early-onset atherosclerotic cardiovascular disease. In pregnant female with FH, apheresis is the preferred treatment because standard therapeutic agents such as statins are contraindicated during pregnancy. LDL adsorption therapy is commonly used; however, after 27 weeks of gestation, it is often switched to dual filtration plasma exchange (DFPP) due to the significant drop in blood pressure caused by bradykinin production. However, DFPP has limited ability to adapt to the increase in circulating plasma volume associated with pregnancy. Here we discuss the case of a 32-year-old female with homozygous FH who underwent different apheresis strategies during her pregnancies. In her first pregnancy, she continued LDL adsorption therapy using DFPP but ultimately delivered a small-for-gestational-age infant via cesarean section. For her second pregnancy, double-filtration plasmapheresis thermo mode, DF-thermo, was introduced to mitigate the limitations of DFPP and LDL adsorption therapies, such as hypotension during apheresis and albumin loss. By minimizing these complications, DF-thermo allowed for a successful delivery without compromising fetal growth. en-copyright= kn-copyright= en-aut-name=SakurabuYoshimasa en-aut-sei=Sakurabu

randomized controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Periodontal disease during pregnancy has been associated with an increased risk of preterm birth (PTB) and low birth weight (LBW). However, most previous interventional studies have reported that scaling and root planing (SRP), a form of basic periodontal treatment, is insufficient to effectively prevent PTB and LBW. Recent systematic reviews and meta-analyses suggest that combining SRP with routine use of chlorhexidine gluconate (CHG) mouthwash may reduce the risk of these adverse birth outcomes by approximately half. This study will be among the first randomized controlled trials (RCTs) to evaluate the potential synergistic effects of this combined approach on improving birth outcomes.
Methods This multi-center, three-arm RCT will be conducted at two hospitals in Dhaka and Bogura, Bangladesh, between April 2025 and September 2026. A total of 480 pregnant women less than 20 weeks’ gestation attending antenatal checkups will be recruited. Participants diagnosed with periodontal disease will be randomly assigned to either an intervention group or a positive control group. Participants without periodontal disease will be assigned to a negative control group. The intervention consists of SRP combined with continued use of CHG mouthwash throughout pregnancy. The primary outcome will be the rate of PTB. Secondary outcomes include the birth weight of the newborn baby, maternal periodontal status, and oral health-related quality of life (OHRQoL). Effectiveness will be assessed by comparing outcomes across the study groups.
Discussion The oral health intervention is expected to improve both birth outcomes and maternal oral health. Demonstrating its effectiveness in a real-world setting may support the integration of oral health care into broader maternal, neonatal, and child health strategies, particularly in resource-limited settings.

Endoplasmic reticulum (ER) stress contributes to PD pathogenesis, with the ER-associated degradation (ERAD) system playing a protective role. HRD1, an ER-resident ubiquitin ligase, and its stabilizer SEL1L are involved in ERAD and neuronal survival. This study investigated alterations in the plasma levels of microRNA-101 (miR-101), which targets SEL1L, in patients with PD, and its potential role as a biomarker.
Results Plasma miR-101 levels in patients with PD significantly decreased compared with those in healthy controls. Receiver operating characteristic curve analysis demonstrated that miR-101 could moderately discriminate patients with PD from healthy individuals (area under the curve?=?0.781, 95% confidence interval?=?0.547?1.00). The optimal cutoff, as determined by the Youden index, was 0.737 (expression ratio relative to that in the healthy control group), yielding a sensitivity of 50% and specificity of 100%. These results suggested that reduced plasma miR-101 expression may reflect the pathophysiological state of PD, and miR-101 has potential as minimally invasive biomarker for PD. en-copyright= kn-copyright= en-aut-name=OmuraTomohiro en-aut-sei=Omura en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KanedaHaruka en-aut-sei=Kaneda en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 ORCID= en-aut-name=SakaneToshiyasu en-aut-sei=Sakane en-aut-mei=Toshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=6 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pharmaceutical Technology, Kobe Pharmaceutical University kn-affil= affil-num=8 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= en-keyword=Parkinson’s disease kn-keyword=Parkinson’s disease en-keyword=microRNA kn-keyword=microRNA en-keyword=Endoplasmic reticulum stress kn-keyword=Endoplasmic reticulum stress en-keyword=HRD1 kn-keyword=HRD1 en-keyword=SEL1L kn-keyword=SEL1L 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=20260707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sex differences and contest experience shape walking patterns in the broad-horned flour beetle en-subtitle= kn-subtitle= en-abstract= kn-abstract=Animal movement patterns vary widely across species, and sex differences are often expected because males typically need to encounter multiple females and acquire resources. In species where males engage in male?male combat using exaggerated weapons, variation in weapon size and contest outcomes is known to influence male reproductive strategies, and may therefore also affect movement behavior. However, sex-specific and male-specific differences in locomotor behavior, particularly in relation to weapon size and social interactions, remain poorly understood. Here, we investigated walking trajectories in the broad-horned flour beetle (Gnatocerus cornutus) to test for (1) sex differences, (2) associations between male weapon size and movement behavior, and (3) the effects of male?male combat. Males exhibited more tortuous and localized movement, whereas females showed straighter and more spatially extensive trajectories. Following contests, all males showed a reduction in activity regardless of contest outcome; however, winners and losers exhibited divergent changes in movement patterns, with winners showing straighter and more spatially extensive trajectories and losers showing more tortuous and localized trajectories. In contrast, body-size-corrected weapon size was not associated with any aspect of walking behavior. These results indicate that locomotor behavior in G. cornutus varies with sex and contest experience, and that variation in walking behavior is more closely associated with social experience than with weapon morphology. en-copyright= kn-copyright= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HashiokaSora en-aut-sei=Hashioka en-aut-mei=Sora kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagayaNaohisa en-aut-sei=Nagaya en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujisawaRyusuke en-aut-sei=Fujisawa en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Arts and Sciences, The University of Tokyo 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=Faculty of Information Science and Engineering, Kyoto Sangyo University kn-affil= affil-num=4 en-affil=Faculty of Environmental Engineering, University of Kitakyushu, kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Turning angle kn-keyword=Turning angle en-keyword= Acceleration kn-keyword= Acceleration en-keyword=Male-male combat kn-keyword=Male-male combat en-keyword=Weapon kn-keyword=Weapon en-keyword=ANTAM kn-keyword=ANTAM END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260722 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=58 cd-vols= no-issue=1 article-no= start-page=47 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260722 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Die Agrarstruktur in Sachsen im 19.

In recent years, university libraries have experienced significant transformations due to the digitization of scholarly information, the expansion of research data management, and the increasing importance of learning support services. As their functions diversify, it has become increasingly difficult to comprehensively understand the structure and roles of university libraries.
　To address this issue, this study focuses on the concept of a library schema, which represents the structural relationships among the elements that constitute a library, including people, resources, services, and activities. While previous research has discussed methods for organizing library components, little attention has been paid to how structural understanding of libraries contributes to knowledge creation and service value.
　Drawing on schema theory, shared cognition in organizational studies, and the knowledge creation theory of Nonaka and Takeuchi, this study constructs a conceptual framework linking library schema visualization, shared cognition, interaction, knowledge creation processes, and library service value. The framework proposes that visualization of library structure through a library schema promotes shared cognition among librarians and users, which in turn facilitates interactions that activate knowledge creation processes. These processes ultimately contribute to the creation of library service value that supports learning and research activities.
　Furthermore, the framework introduces two moderating factors: schema representation methods and operational constraints of library management. Based on this framework, six research propositions are presented.
　By integrating concepts from library and information science with knowledge management theory, this study contributes to the theoretical understanding of university libraries as knowledge infrastructures and provides a foundation for future empirical research on knowledge creation in library environments. en-copyright= kn-copyright= en-aut-name=KobayashiKensuke en-aut-sei=Kobayashi en-aut-mei=Kensuke kn-aut-name=小林健輔 kn-aut-sei=小林 kn-aut-mei=健輔 aut-affil-num=1 ORCID= en-aut-name=MiyazakiSatoru en-aut-sei=Miyazaki en-aut-mei=Satoru kn-aut-name=宮崎悟 kn-aut-sei=宮崎 kn-aut-mei=悟 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学研究・イノベーション共創機構 affil-num=2 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260722 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=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= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaAiri en-aut-sei=Yamada en-aut-mei=Airi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MisawaRyo en-aut-sei=Misawa en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= en-keyword=disaster education kn-keyword=disaster education en-keyword=local disaster knowledge kn-keyword=local disaster knowledge en-keyword=disaster literacy kn-keyword=disaster literacy en-keyword=damage estimation abilities kn-keyword=damage estimation abilities en-keyword=community resilience kn-keyword=community resilience END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue= article-no= start-page=105422 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=Pathological features of residual head and neck cancer after near-infrared photoimmunotherapy: implications of an unfavorable tumor immune microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Near-infrared photoimmunotherapy has been approved in Japan for unresectable locally advanced or recurrent head and neck cancer. While this therapy theoretically induces selective necrosis of epidermal growth factor receptor-expressing tumor cells following administration of cetuximab sarotalocan sodium and irradiation with 690-nm light, residual disease is not uncommon in clinical practice. The mechanisms underlying such persistence remain poorly understood.
Methods: We examined two patients with head and neck squamous cell carcinoma who underwent salvage resection due to residual disease after four cycles of near-infrared photoimmunotherapy. Resected specimens were subjected to histopathological evaluation, including immunohistochemistry for epidermal growth factor receptor, cluster of differentiation 8, programmed cell death protein 1, and forkhead box P3 proteins.
Results: In both cases, residual tumor cells were predominantly localized in the superficial mucosal layers, while deeper layers were replaced by fibrosis. All residual tumors retained expression of epidermal growth factor receptor. Lymphocytic infiltration was sparse, with scattered cluster of differentiation 8-positive cells but few programmed cell death protein 1-positive or forkhead box P3-positive lymphocytes. These findings suggest that the tumor microenvironment surrounding residual tumors may have been unfavorable for the induction of robust antitumor immune responses.
Conclusion: Residual tumors after near-infrared photoimmunotherapy can occur despite adequate laser irradiation and epidermal growth factor receptor expression. Our observations imply that insufficient immune activation within the tumor microenvironment may contribute to treatment resistance. Further characterization of the post-photoimmunotherapy tumor microenvironment will be essential to better understand treatment mechanisms and to optimize therapeutic efficacy. en-copyright= kn-copyright= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=NaoiYuto en-aut-sei=Naoi en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology - Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=NIR-PIT kn-keyword=NIR-PIT en-keyword=EGFR kn-keyword=EGFR en-keyword=CD8 kn-keyword=CD8 en-keyword=PD-1 kn-keyword=PD-1 en-keyword=FOXP3 kn-keyword=FOXP3 en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment en-keyword=Photoimmunotherapy kn-keyword=Photoimmunotherapy en-keyword=Head and neck cancer kn-keyword=Head and neck cancer END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=3 article-no= start-page=104642 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=Relationship between the Hounsfield Unit value of the greater trochanter and the risk of greater trochanteric fractures in anterolateral muscle-sparing minimally invasive total hip arthroplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: No previous studies have investigated the association between the risk of greater trochanteric fractures and the Hounsfield Unit (HU) of the greater trochanter in muscle-sparing minimally invasive total hip arthroplasty (MIS-THA). This study aimed to investigate the risk factors for greater trochanteric fractures in anterolateral MIS-THA.
Hypothesis: Lower HU values of the greater trochanter are associated with a higher risk of intraoperative and early postoperative greater trochanteric fractures.
Patients and methods: This single-center retrospective observational study included 223 patients (257 hips) who underwent primary THA for osteoarthritis or osteonecrosis between January 2010 and August 2024 using a minimally invasive anterolateral approach in the lateral position. All surgeries were performed by four surgeons. Preoperative CT was used to reconstruct coronal sections including the femoral head center and proximal femoral axis, and cancellous HU values of the greater trochanter were measured. Postoperative CT (1 week) with metal artifact reduction was routinely performed; fractures were defined as cortical fracture lines on 3D-reconstructed CT and assessed by two independent orthopedic surgeons. Patients were divided into two groups according to the presence or absence of fractures.
Results: The incidence of greater trochanteric fractures was 6.6% (17/257 hips). Twelve of these fractures (70.6%) were recognized intraoperatively or immediately postoperatively. Full hydroxyapatite (HA)-coated stems were associated with an increased fracture risk compared with other designs (relative risk [RR], 2.68; 95% CI, 1.07?6.68). Age, sex, BMI, ASA physical status, and diagnosis were not significantly associated with fractures. Multivariate analysis identified lower HU values (odds ratio [OR], 0.973; p < 0.0001) and full HA-coated stems (OR, 13.3; p = 0.04) as independent predictors. Receiver operating characteristic (ROC) analysis determined an optimal cut-off of 72.0 HU (sensitivity, 0.941; specificity, 0.742), with a value ?72.0 HU demonstrating high predictive power (RR, 36.7; p < 0.0001).
Conclusion: Preoperative measurement of HU values in the greater trochanter is a useful screening tool for identifying patients at increased risk of fractures in anterolateral MIS-THA. While an HU value of ? 72.0 necessitates careful intraoperative management and increased vigilance, it should be interpreted as an indicator of risk rather than a definitive predictor of fracture due to its moderate specificity.

Isolated substitutional boron atoms introduce holes; however, the fraction of electrically inactive boron atoms increases at higher doping concentrations. This has been attributed to boron aggregation and hydrogen passivation, although their structural identification based on atomic arrangement has yet to be experimentally verified. Here we show the origin of multiple chemical states in homoepitaxially grown boron-doped diamond thin films by analyzing the atomic environment of boron using spectro-photoelectron holography. Our analysis identifies boron dimers and boron-hydrogen complexes, with hydrogen occupying different atomic sites that give rise to distinct chemical shifts. These results suggest that hydrogen incorporation during growth leads to passivation of boron acceptors. We demonstrate that photoelectron holography serves as a promising tool for imaging hydrogen as well as determining the atomic sites of dopants. en-copyright= kn-copyright= en-aut-name=TomitaHiroto en-aut-sei=Tomita en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HosodaWataru en-aut-sei=Hosoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniguchiTakumi en-aut-sei=Taniguchi en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraHirokazu en-aut-sei=Fujiwara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KataokaNoriyuki en-aut-sei=Kataoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KageuraTaisuke en-aut-sei=Kageura en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakanoYoshihiko en-aut-sei=Takano en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaradaHiroshi en-aut-sei=Kawarada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OguchiTamio en-aut-sei=Oguchi en-aut-mei=Tamio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsushitaTomohiro en-aut-sei=Matsushita en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Science and Technology, Nara Institute of Science and Technology kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Advanced Materials Science, Graduate School of Frontier Sciences, The University of Tokyo kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Sensing Technology Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=7 en-affil=Research Center for Materials Nanoarchitectonics, National Institute for Materials Science kn-affil= affil-num=8 en-affil=Faculty of Science and Engineering, Waseda University kn-affil= affil-num=9 en-affil=Center for Spintronics Research Network, The University of Osaka kn-affil= affil-num=10 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Science and Technology, Nara Institute of Science and Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=16760 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=Asthma-like bronchodilator responsiveness in patients with neuronal intranuclear inclusion disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative condition characterized by the presence of intranuclear inclusions in neuronal and visceral cells. Patients with NIID can present respiratory symptoms; however, data on pulmonary functions in NIID are lacking. This study investigated the respiratory conditions in NIID patients diagnosed with histopathological and genetic studies. We conducted two spirometries before and after administrating the bronchodilator in NIID patients with asthmatic histories or symptoms. We statistically compared pre- and post-measured values including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Before two spirometries, we also measured fractional concentration of exhaled nitric oxide (FeNO), if possible. Of the 51finally enrolled patients, 17 (33.3%, 95% CI 20.8% to 47.9%) patients had asthmatic histories or symptoms, and 14 patients received two spirometries. After administrating the bronchodilator, FEV1 and PEF significantly increased by 150 mL (6.01%, p?=?0.002) and 260 mL/s (6.72%, p?=?0.017), respectively. The median (interquartile range) of FeNO measured in nine patients was 15 (10?21) ppb. Patients with NIID have airflow reversibility like asthma. This condition appears to be less associated with airway inflammation and may be related to autonomic dysfunction. en-copyright= kn-copyright= en-aut-name=TaharaDaisuke en-aut-sei=Tahara

study, we evaluated the in vivo activity of the E1 element within the insulin promoter region. While we successfully obtained mice carrying a deletion exclusively in the E1 element of Ins2 (2E mice), we were unable to obtain mice with a deletion limited to the E1 element of Ins1. To assess the role of the E1 element in Ins1, we compared the mice carrying deletions in the GG2-GG1/A2-C1 elements with or without an additional E1 element deletion (1GC/1GCE mice). 1GCE2E mice developed diabetes. In contrast, 1GCE23 mice (without deletion in the E1 element of Ins2) did not develop diabetes, suggesting that the E1 element of Ins2 is critical for transcriptional regulation. Furthermore, 1GC2E mice (presence of the E1 element of Ins1) developed diabetes. However, the severity of the disease was milder in 1GC2E mice than in 1GCE2E mice, indicating that the E1 element of Ins1 also contributes to transcriptional regulation. These data suggest that the E1 elements in both Ins1/2 promoters are regulated for the in vivo transcription of insulin genes in mice. en-copyright= kn-copyright= en-aut-name=NoguchiHirofumi en-aut-sei=Noguchi en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Miyagi-ShiohiraChika en-aut-sei=Miyagi-Shiohira en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitohIssei en-aut-sei=Saitoh en-aut-mei=Issei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Regenerative Medicine, Graduate School of Medicine, University of the Ryukyus kn-affil= affil-num=2 en-affil=Department of Regenerative Medicine, Graduate School of Medicine, University of the Ryukyus kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatric Dentistry, Asahi University School of Dentistry kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=1050 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260423 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Differences in understanding of explanations and risk perception between dental staff and patients: a questionnaire study at a university hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and purpose: Proper self-care necessitates behavioral changes, underpinned by correct knowledge. Oral health literacy (OHL) research constitutes a fundamental foundation for fostering effective self-care practices. However, the extent of the awareness gap between patients and dental staff regarding explanations provided during treatment remains unknown. This descriptive study was conducted to serve as an initial step in bridging this gap.
Methods: Questionnaires were distributed to 92 dental staff members and 205 patients at university hospitals, with responses from 72 staff members and 157 patients.
Results: In the category assessing understanding of explanations (patient vs. dental staff), patients’ self-assessed understanding exceeded the dental staff’s estimates in three aspects: disease name (p?=?0.03, r?=?0.17), treatment period (p?=?0.01, r?=?0.21), and pain relief (p?=?0.01, r?=?0.19). Regarding health self-awareness, the high-scoring group significantly outperformed the low-scoring group in explaining treatment risks (p?=?0.03, r?=?0.21) and understanding (p?=?0.01, r?=?0.23). Nevertheless, patients’ risk recognition was higher than that of dental staff in three aspects: root canal treatment (p? Conclusion: Dental staff should not be satisfied merely with having "explained" something to the patient; they must engage in a confirmation process to verify the patient's correct understanding of the information or to identify excessive anxiety. en-copyright= kn-copyright= en-aut-name=OtomoShiho en-aut-sei=Otomo en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujisakiMaoko en-aut-sei=Fujisaki en-aut-mei=Maoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanagaseRisako en-aut-sei=Yanagase en-aut-mei=Risako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NoritakeKanako en-aut-sei=Noritake en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=SugiharaTaro en-aut-sei=Sugihara en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=School of Environment and Society, Institute of Science Tokyo kn-affil= affil-num=2 en-affil=School of Environment and Society, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=School of Environment and Society, Institute of Science Tokyo kn-affil= affil-num=4 en-affil=Institute of Science Tokyo Hospital, Institute of Science Tokyo kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=School of Environment and Society, Institute of Science Tokyo kn-affil= en-keyword=Dental care kn-keyword=Dental care en-keyword=Dentist-patient relations kn-keyword=Dentist-patient relations en-keyword=Recognition gaps kn-keyword=Recognition gaps en-keyword=Oral health literacy kn-keyword=Oral health literacy END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page=2879891 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=A Rare Case of Hyperplastic Dental Follicle Presenting With an Unusually Large Radiolucent Area en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hyperplastic dental follicle (HDF) is a rare odontogenic hamartomatous lesion typically associated with unerupted teeth in children and adolescents and is often found incidentally on radiographic imaging. HDF usually presents as a pericoronal radiolucency of 2?3?mm in diameter and is commonly difficult to distinguish from dentigerous cysts on radiographs. We report an unusual case of HDF in an 11-year-old male who was referred for evaluation of delayed eruption of the left maxillary canine. Panoramic radiography and cone-beam computed tomography (CBCT) revealed a remarkably large radiolucent area, with a maximum dimension of 25.3?mm. The initial clinical diagnosis was a dentigerous cyst; however, incisional biopsy revealed solid tissue characteristics, and histopathological examination confirmed HDF, with no evidence of cystic lining, neoplastic transformation, or inflammation. Following the patient′s and parents′ preference for complete removal, resection of the lesion together with extraction of the impacted canine was performed under general anesthesia. At the 6-month follow-up, no recurrence was observed and bone regeneration was confirmed on radiographic examination. This case underscores the diagnostic challenge posed by atypical radiographic findings and highlights the necessity of histopathological confirmation. Given the exceptional size and potential for recurrence, long-term follow-up is warranted. en-copyright= kn-copyright= en-aut-name=OtsukiSatoshi en-aut-sei=Otsuki en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadoyaKoichi en-aut-sei=Kadoya en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiChizuru en-aut-sei=Kobayashi en-aut-mei=Chizuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=case report kn-keyword=case report en-keyword=hyperplastic dental follicle kn-keyword=hyperplastic dental follicle en-keyword=large radiolucent lesion kn-keyword=large radiolucent lesion en-keyword=odontogenic hamartoma kn-keyword=odontogenic hamartoma en-keyword=unerupted tooth kn-keyword=unerupted tooth END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=11 article-no= start-page=1688 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=GLP-1 Receptor Agonists in the Rehabilitation of Patients with Heart Failure: Mechanisms, Clinical Evidence, and Future Perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heart failure (HF) remains associated with high morbidity and mortality, with heart failure with preserved ejection fraction (HFpEF) becoming increasingly prevalent and therapeutically challenging despite advances in pharmacological and rehabilitative care. Beyond their glucose-lowering effects, glucagon-like peptide-1 receptor agonists (GLP-1RAs) confer cardiometabolic benefits and may serve as effective adjuncts to cardiac rehabilitation (CR), particularly in obese patients with HFpEF. Obesity plays a central role in the pathophysiology of HFpEF, and GLP-1RAs promote weight loss, reduce insulin resistance and leptin signaling, and improve hemodynamic and metabolic abnormalities associated with HFpEF. Accumulating evidence suggests that the benefits of GLP-1RAs are phenotype-specific and more pronounced in patients with HFpEF than in patients with HF with reduced ejection fraction. Current clinical guidelines recommend GLP-1RAs for patients who have type 2 diabetes mellitus and established cardiovascular (CV) disease or are at high CV risk, with recent updates recognizing their potential benefits in patients with HFpEF and obesity. Cardiac rehabilitation, delivered through multidisciplinary programs, remains a cornerstone of HF management. Although caloric restriction and aerobic exercise can be beneficial in patients with HFpEF and obesity, these interventions alone are often insufficient. Sarcopenia is common in older patients with HFpEF and contributes to adverse outcomes, underscoring the importance of incorporating resistance training into CR programs. The most frequent adverse effects of GLP-1RAs are gastrointestinal events, which are generally mild to moderate but may lead to treatment discontinuation in some patients. Future studies should investigate the potential synergistic effects of GLP-1RAs and CR, clarify their long-term safety and efficacy in HF populations, and define their role beyond obese HFpEF phenotypes. en-copyright= kn-copyright= en-aut-name=SuastikaLuh Oliva Saraswati en-aut-sei=Suastika en-aut-mei=Luh Oliva Saraswati kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BandoYasuko K. en-aut-sei=Bando en-aut-mei=Yasuko K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoshinoKeiji en-aut-sei=Hoshino en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoitabashiNorimichi en-aut-sei=Koitabashi en-aut-mei=Norimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoYukihiro en-aut-sei=Saito en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Physiology and Cardiovascular Biology, Mie University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Division of Cardiology, Gunma Prefectural Cardiovascular Center kn-affil= affil-num=4 en-affil=Division of Cardiology, Gunma Prefectural Cardiovascular Center kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=GLP-1 receptor agonists kn-keyword=GLP-1 receptor agonists en-keyword=heart failure kn-keyword=heart failure en-keyword=cardiac rehabilitation kn-keyword=cardiac rehabilitation en-keyword=obesity kn-keyword=obesity en-keyword=sarcopenia kn-keyword=sarcopenia END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=7 article-no= start-page=105 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=WT1 mRNA in peripheral blood enables early prognostic stratification in AML patients receiving venetoclax and azacitidine therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Venetoclax and azacitidine (VEN/AZA), which target BCL-2 and DNA methylation, have demonstrated substantial efficacy, particularly in older or unfit patients with acute myeloid leukemia (AML). Wilms’ Tumor-1 (WT1) mRNA, measurable in peripheral blood (PB), is an established biomarker for monitoring treatment response and predicting AML prognosis. We conducted a retrospective analysis of patients with AML treated with VEN/AZA within the Okayama Hematology Study Group (OHSG). Patients who showed a marked reduction in PB WT1 mRNA levels from baseline after the first or second treatment cycle had significantly improved overall survival (OS) and progression-free survival (PFS). Moreover, achieving PB WT1 mRNA negativity-regardless of whether this occurred early or later in the therapy?was consistently associated with superior OS and PFS. These findings suggest that PB WT1 mRNA is a sensitive and reliable biomarker for predicting treatment response and long-term outcomes in patients with AML receiving VEN/AZA. en-copyright=

en-subject= kn-subject= en-title= kn-title=Insomnia and the Risk of Atrial Fibrillation: A Nationwide, Real‐World Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Insomnia is one of the most prevalent diseases observed in clinical practice, contributing to increased death and a range of chronic diseases. While numerous studies have explored the relationship between insomnia and cardiovascular disease, research on its association with atrial fibrillation (AF) remains limited. This study aimed to investigate the association between insomnia and incident AF in the general population by comprehensive, nationwide, real‐world data in Japan.
Methods: A total of 1?780?764 individuals without prior cardiovascular disease including AF from the DeSC database were included between April 2014 and August 2023. Insomnia was defined by International Classification of Diseases, Tenth Revision (ICD‐10) codes (F510, G470) before the baseline health checkup. The primary outcome was incident AF (I480?I482 and I489). Cox proportional hazards models were used to estimate hazard ratios of AF according to present insomnia (versus absent).
Results: Insomnia was observed in 216?919 individuals (12.2%), showing a significant association with incident AF after adjusting for potential confounding factors (adjusted hazard ratio, 1.14 [95% CI, 1.10?1.18]). Among subgroups, a similar pattern in the association between insomnia and incident AF was seen, while the association was stronger in younger individuals aged <65?years (versus ?65?years) and women (versus men) (P for interaction=0.01 and 0.03, respectively).
Conclusions: Insomnia was significantly associated with the risk of AF. It highlighted the importance of recognizing insomnia as a risk factor for AF, given its high prevalence in the general population and the substantial impact of AF on quality of life and prognosis.

en-title= kn-title=Sebastidae-specific food allergy causing anaphylaxis: a pediatric case report and fish allergen analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Fish allergy affects approximately 0?0.3% of the population. Parvalbumin is the major allergen in fish allergy, and patients with fish allergy sensitized to parvalbumin demonstrate allergic reactions to various fish species. However, a subset of patients exhibits allergic responses to only specific fish species. Fish of the Sebastidae family, widely consumed in Asian, North American, and European countries, has rarely been reported as an allergenic trigger.
Case presentation A 14-year-old Japanese boy visited our clinic for evaluation of fish allergy after experiencing allergic reactions to Sebastes alutus (Alaskan rockfish). He developed respiratory symptoms, eyelid edema, and skin erythema after consuming a meal containing Sebastes alutus, suggesting anaphylaxis; however, he was able to consume many other fish species without any issues. Skin prick tests and basophil activation tests using fish species from the Sebastidae family showed positive reactions, whereas other fish species that the patient could tolerate showed negative reactions. Immunoblot analysis performed to identify the causative allergen revealed two IgE-binding bands (17 and 110 kDa) in Sebastidae, distinct from parvalbumin. Mass spectrometry identified these proteins as alpha-actinin-3b, ATPase sarcoplasmic/endoplasmic reticulum Ca2?+?transporting 1, and several myosin-related proteins.
Conclusions This case highlights the need for clinicians to recognize fish allergy specific to the Sebastidae family. Identifying the causative non-parvalbumin allergens would improve understanding of fish allergy diversity and individualized dietary management for patients. Additional cases and detailed analyses are necessary to identify the specific allergens involved in Sebastidae allergy. en-copyright= kn-copyright= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pediatric Acute Diseases, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Food allergy kn-keyword=Food allergy en-keyword=Fish allergy kn-keyword=Fish allergy en-keyword=Sebastidae kn-keyword=Sebastidae en-keyword=Basophil activation test kn-keyword=Basophil activation test END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=1 article-no= start-page=1 end-page=10 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=Similar functional outcomes but different remodeling patterns: A minimum 5-years radiographic comparison of short fit-and-fill stem and quadrangular taper 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=17 cd-vols= no-issue=1 article-no= start-page=5862 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The role of Pth1r in posterior cranium cartilage regulation and craniosynostosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Craniosynostosis is a major craniofacial congenital disorder that causes developmental complications. During normal cranial development, intramembranous ossification forms the flat bones and sutures, while cartilage appears transiently in the posterior calvarial region. However, in craniosynostosis, premature suture fusion disturbs normal calvarial morphogenesis. To clarify the role of transient cartilage in this morphogenetic disruption, we investigated its molecular regulation and pathology in mice, focusing on parathyroid hormone 1 receptor (Pth1r) signaling. Conditional deletion of Pth1r in the cranial mesenchyme unexpectedly caused acrocephalic dysmorphology and craniosynostosis, with altered cartilage differentiation. Occipito?interparietal synostosis consistently occurred in Pth1r-ablated Gli1+ and Acan+ lineages, but not after adult Gli1-CreERT2 deletion, indicating a developmental role. Bulk and single-cell RNA-seq analysis revealed nine mesenchymal subsets, with mutant cells showing abnormal chondrocyte differentiation and upregulated Indian hedgehog (Ihh) signaling. These findings indicate that Pth1r maintains proper chondrogenic regulation during calvarial development, and its loss induces craniosynostosis through Ihh overactivation. en-copyright= kn-copyright= en-aut-name=AmanoKatsuhiko en-aut-sei=Amano en-aut-mei=Katsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkuzakiDaisuke en-aut-sei=Okuzaki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimotoYuji en-aut-sei=Fujimoto en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiuYu-Chen en-aut-sei=Liu en-aut-mei=Yu-Chen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KogoMikihiko en-aut-sei=Kogo en-aut-mei=Mikihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IidaSeiji en-aut-sei=Iida en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Laboratory of Human Immunology (Single Cell Genomics), WPI Immunology Frontier Research Center, University of Osaka kn-affil= affil-num=3 en-affil=Laboratory of Human Immunology (Single Cell Genomics), WPI Immunology Frontier Research Center, University of Osaka kn-affil= affil-num=4 en-affil=Laboratory of Human Immunology (Single Cell Genomics), WPI Immunology Frontier Research Center, University of Osaka kn-affil= affil-num=5 en-affil=The First Department of Oral and Maxillofacial Surgery, Osaka University Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=30 end-page=33 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=Study of Signal Separation and Demodulation Techniques Considering IQ Imbalance by Stored Data Batch Signal Processing en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the arrival of the IoT era, the problem of interference has become even more serious, and the challenge is to establish techniques for separating and demodulating collide signals. To achieve this, we are conducting research on stored data batch signal processing technology using short-time Fourier transform (STFT). In this paper, we used a feature quantity demodulation method proposed as a method for stored data batch signal processing to evaluate the effect of IQ imbalance, which is a factor in signal degradation in the transmitter, on signal separation and demodulation performance. Furthermore, we proposed a receiver configuration that estimates the amount of degradation due to IQ imbalance from the extracted feature quantities and compensates for the signal degradation. Computer simulation results confirmed that the proposed compensation method can improve signal separation and demodulation performance when degraded by IQ imbalance. en-copyright= kn-copyright= en-aut-name=MitaYudai en-aut-sei=Mita en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraokaYuta en-aut-sei=Hiraoka en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HikasaTomofumi en-aut-sei=Hikasa en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomisatoShigeru en-aut-sei=Tomisato en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DennoSatoshi en-aut-sei=Denno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UeharaKazuhiro en-aut-sei=Uehara en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=stored data batch signal processing kn-keyword=stored data batch signal processing en-keyword=short-time Fourier transform kn-keyword=short-time Fourier transform en-keyword=IQ imbalance kn-keyword=IQ imbalance en-keyword=IQ imbalance compensation kn-keyword=IQ imbalance compensation 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.

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=136 cd-vols= no-issue=10 article-no= start-page=e195021 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spatial single-cell proteotyping reveals immunotherapy-resistant features within the complex tumor microenvironment of metastatic NSCLC en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND. Immune checkpoint inhibitors (ICIs) targeting the programmed cell death 1 axis have revolutionized metastatic non?small cell lung cancer (mNSCLC) treatment. However, disease progression remains a concern, and the role of the complex tumor microenvironment (TME) in treatment failure is not fully understood.
METHODS. In this biomarker study involving 103 patients with mNSCLC, including 81 patients who received ICI treatment, we evaluated the association between heterogeneous immune cell subsets and ICI efficacy through single-cell spatial profiling of pretreatment tumor tissue, using a 29-marker multiplex IHC platform built for in-depth dissection of the TME.
RESULTS. Among various types of intratumoral lymphocytes, including Th1, Treg, and NK cells, only CD8+ T cells (tumor-infiltrating lymphocytes [TILs]) were associated with ICI efficacy. Computational tissue segmentation underscored the importance of direct physical interactions between CD8+ TILs and cancer cells for ICI efficacy. TIL phenotyping identified CD39/CD103/Ki-67 positivity as a hallmark of exhausted yet functional tumor-reactive CD8+ TILs. Immunosuppressive tumor-associated macrophages (TAMs) and cancer-associated fibroblasts were independent unfavorable adversaries. High CD73 expression on cancer cells was suggested to confer tolerance to ICI in EGFR/ALK-oncogene+ NSCLC, potentially through M2-TAM accumulation and aberrant angiogenesis.
CONCLUSION. Our study delineates the clinical relevance of heterogeneous immune cell subsets in ICI-treated mNSCLC, aiding the development of targeted therapeutic strategies. en-copyright= kn-copyright= en-aut-name=IsomotoKohsuke en-aut-sei=Isomoto en-aut-mei=Kohsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HarataniKoji en-aut-sei=Haratani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujikawaTakahiro en-aut-sei=Tsujikawa en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakutaniYusuke en-aut-sei=Makutani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakedaMasayuki en-aut-sei=Takeda en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YonesakaKimio en-aut-sei=Yonesaka en-aut-mei=Kimio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaKaoru en-aut-sei=Tanaka en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwasaTsutomu en-aut-sei=Iwasa en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaiKazuko en-aut-sei=Sakai en-aut-mei=Kazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishioKazuto en-aut-sei=Nishio en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ItoAkihiko en-aut-sei=Ito en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakagawaKazuhiko en-aut-sei=Nakagawa en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HayashiHidetoshi en-aut-sei=Hayashi en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=2 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Otolaryngology?Head and Neck Surgery, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Kindai University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=7 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=8 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=9 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Genome Biology, Kindai University Faculty of Medicine kn-affil= affil-num=11 en-affil=Department of Genome Biology, Kindai University Faculty of Medicine kn-affil= affil-num=12 en-affil=Department of Pathology, Kindai University Faculty of Medicine kn-affil= affil-num=13 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=5485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bacterial collagenase harnesses collagen geometry for processive cleavage en-subtitle= kn-subtitle= en-abstract= kn-abstract=Collagen, the major structural protein in the animal extracellular matrix, forms a triple helix that resists proteolysis and requires specialised enzymes for degradation. Flesh-eating bacteria secrete collagenases that unwind the collagen triple helix and processively trim Gly?X?Y triplet repeats, yet the molecular basis of this process has remained obscure. Here, cryo-electron microscopy reveals how Hathewaya histolytica collagenase ColH engages its substrate and exploits the helix’s architecture for catalysis. ColH encircles a single collagen triple helix in a closed-ring conformation and, through dynamic domain motions, dehydrates and destabilises it. The enzyme undergoes substrate-assisted twisting to adopt a rigid ratcheted conformation, in which one chain is bent into a tripeptide-long ‘bight’ and threaded into the active site for cleavage, while two uncut strands are partitioned to non-catalytic sites. Release of the bight appears to reset the enzyme, with the uncut strands serving as guiding tracks. Repeated cycling between dynamic and rigid states likely enables triplet-by-triplet translocation, allowing ColH to harness collagen’s geometry for processive degradation. These findings reveal a bacterial strategy for collagen unwinding and cleavage distinct from that of mammalian collagenases, highlighting divergent evolutionary solutions for degrading one of nature’s most intractable substrates. en-copyright= kn-copyright= en-aut-name=OkiHiroya en-aut-sei=Oki en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BonsuAdjoa en-aut-sei=Bonsu en-aut-mei=Adjoa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiKazunori en-aut-sei=Fujii en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaRyo en-aut-sei=Masuda en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HendersonNicholas en-aut-sei=Henderson en-aut-mei=Nicholas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MimaTakehiko en-aut-sei=Mima en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoideTakaki en-aut-sei=Koide en-aut-mei=Takaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoradiMahmoud en-aut-sei=Moradi en-aut-mei=Mahmoud kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakonJoshua en-aut-sei=Sakon en-aut-mei=Joshua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawaharaKazuki en-aut-sei=Kawahara en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Infection Metagenomics, Genome Information Research Center, Research Institute for Microbial Diseases, The University of Osaka kn-affil= affil-num=2 en-affil=Department of Dental Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry and Biochemistry, University of Arkansas kn-affil= affil-num=4 en-affil=Department of Chemistry and Biochemistry, School of Advanced Science and Engineering, Waseda University kn-affil= affil-num=5 en-affil=Waseda Research Institute for Science and Engineering, Waseda University kn-affil= affil-num=6 en-affil=Department of Chemistry and Biochemistry, University of Arkansas kn-affil= affil-num=7 en-affil=Department of Medical Technology, Faculty of Health Sciences, Ehime Prefectural University of Health Sciences kn-affil= affil-num=8 en-affil=Department of Chemistry and Biochemistry, School of Advanced Science and Engineering, Waseda University kn-affil= affil-num=9 en-affil=Department of Chemistry and Biochemistry, University of Arkansas kn-affil= affil-num=10 en-affil=Department of Bacteriology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Chemistry and Biochemistry, University of Arkansas kn-affil= affil-num=12 en-affil=Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=19282 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dual-calibration RT-qPCR reveals distinct dnaK1/2/3 and groEL1/2 expression dynamics under heat and acid stress in the sinefungin producer Streptomyces incarnatus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Streptomyces incarnatus NRRL8089 produces sinefungin, a nucleoside antibiotic whose yield is enhanced under defined environmental stresses. Here, dual-calibration RT-qPCR was used to resolve paralogue-specific expression dynamics of the dnaK and groE chaperone systems under heat and acid stress conditions that increase sinefungin titres. The canonical dnaK1?dnaJ1 and groES?groEL1 operons exhibited moderate induction, whereas monocistronic paralogues (dnaK2, dnaK3 and groEL2) showed markedly higher inducibility, with up to ~?125-fold increases relative to baseline expression. Promoter analyses revealed conserved inverted repeats and differences in predicted secondary-structure stability, suggesting that promoter architecture contributes to paralogue-specific responsiveness. Structural modelling indicated divergence among DnaK paralogues in regions associated with substrate interaction, whereas GroEL paralogues retained a conserved overall scaffold, consistent with kinetic rather than structural differentiation. Together, these findings indicate that duplicated paralogues are not functionally redundant but are differentially regulated to partition proteostasis capacity under stress. This paralogue-specific regulation may provide a framework linking environmental perturbation to secondary-metabolite production in actinomycetes. en-copyright= kn-copyright= en-aut-name=Xiao-HuiZhao en-aut-sei=Xiao-Hui en-aut-mei=Zhao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuboMao en-aut-sei=Kubo en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamagataHaruka en-aut-sei=Yamagata en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakashimaYuriko en-aut-sei=Nakashima en-aut-mei=Yuriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasunumaTomohisa en-aut-sei=Hasunuma en-aut-mei=Tomohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanaoTadayoshi en-aut-sei=Kanao en-aut-mei=Tadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Heat shock kn-keyword=Heat shock en-keyword=Acid stress kn-keyword=Acid stress en-keyword=dnaK kn-keyword=dnaK en-keyword=hspR kn-keyword=hspR en-keyword=groES kn-keyword=groES en-keyword=groEL kn-keyword=groEL en-keyword=Sinefungin kn-keyword=Sinefungin en-keyword=Streptomyces incarnatus kn-keyword=Streptomyces incarnatus END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=20445 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metastatic promoting role of mesenchymal stem cells in oral squamous cell carcinoma revealed by an improved bone marrow chimeric model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mesenchymal stem cells (MSCs) are essential stromal regulators that coordinate tissue repair, angiogenesis, and immune balance. Within tumours, MSCs remodel the microenvironment and influence disease progression, yet their systemic contribution remains unclear due to the limited recovery of functional MSCs in conventional bone marrow transplantation models. Here, we developed an improved bone marrow collection (iBMC) method using enzymatic digestion, which markedly increases MSC yield while preserving their native phenotype. GFP bone marrow chimeric mice generated by iBMC and conventional transplantation displayed comparable hematopoietic reconstitution but differed in MSC abundance, enabling direct analysis of MSC-specific effects under physiological conditions. In mouse models of oral squamous cell carcinoma (OSCC), MSCs profoundly affected tumour development. MSC-deficient tumours exhibited necrosis and infiltration of immature myeloid-derived suppressor cells (MDSCs), whereas MSC-rich tumours showed enhanced vascularisation, adaptive immune infiltration, and stromal remodelling. Notably, lung metastasis occurred only in MSC-rich mice, accompanied by bone marrow?derived endothelial activation and TNF-α?driven inflammation. Pharmacological inhibition of LepR signalling using SHU9119 unexpectedly increased metastasis, underscoring the dual, context-dependent functions of MSCs. These findings establish iBMC as a reproducible and physiologically relevant model to study MSC-mediated regulation of tumour immunity, angiogenesis, and metastasis. en-copyright= kn-copyright= en-aut-name=EainHtoo Shwe en-aut-sei=Eain en-aut-mei=Htoo Shwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SanouSho en-aut-sei=Sanou en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoeYamin en-aut-sei=Soe en-aut-mei=Yamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OoMay Wathone en-aut-sei=Oo en-aut-mei=May Wathone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PiaoTianyan en-aut-sei=Piao en-aut-mei=Tianyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MinZin Zin en-aut-sei=Min en-aut-mei=Zin Zin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama University kn-affil= en-keyword=Mesenchymal stem cells (MSCs) kn-keyword=Mesenchymal stem cells (MSCs) en-keyword=Oral squamous cell carcinoma (OSCC) kn-keyword=Oral squamous cell carcinoma (OSCC) en-keyword=Bone marrow transplantation kn-keyword=Bone marrow transplantation en-keyword=Chimeric mouse models kn-keyword=Chimeric mouse models en-keyword=Tumour microenvironment (TME) kn-keyword=Tumour microenvironment (TME) END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=1 article-no= start-page=e01108-24 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=Genomic epidemiology and genetic characteristics of clinical Campylobacter species cocirculating in West Bengal, India, 2019, using whole genome analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Campylobacter species are the most common pathogens responsible for foodborne gastroenteritis worldwide. India is a region with frequent diarrheal infections and a high level of Campylobacter infection incidence, but the detailed genomic information is limited. This study aimed to characterize 112 isolates of Campylobacter from diarrhea patients at two hospitals in Kolkata, West Bengal, by whole genome analysis. The Campylobacter isolates consisted of 90 C. jejuni, 20 C. coli, and 2 C. lari isolates. Multilocus sequence typing analysis revealed that the largest sequence type (ST) populations were ST-2131 in C. jejuni and ST-830 in C. coli and seven novel STs were found in C. jejuni and one in C. coli. Notably, ST-2131, which is rarely seen elsewhere, was positive for a sialylated LOS-related gene (wlaN +neuA + cstIII) associated with Guillain-Barr? syndrome. Antibiotic resistance factors predicted from the genome sequence included blaOXA variants (58.9%), tet(O) (54.5%), tet(W) (0.9%), ant(6)-Ia (0.9%), mutation in GyrA (T86I, T86I+D90N, T86I+P104S, T86I+D90N+P104S) (79.5%), and mutation in 23S rRNA (A2075G) (12.5%). In addition to the high drug resistance of Campylobacter in Kolkata, Campylobacter pathogens were circulating that may be associated with Guillain-Barr? syndrome. This study indicates the importance of genomic analysis in the surveillance of pathogens, which provides genomic information on genetic diversity, virulence mechanisms, and determinants of antimicrobial resistance. en-copyright= kn-copyright= en-aut-name=MoritaDaichi en-aut-sei=Morita en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=MaruyamaFumito en-aut-sei=Maruyama en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KandaMiyuki en-aut-sei=Kanda en-aut-mei=Miyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaharaHidetoshi en-aut-sei=Tahara en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MukherjeePiyali en-aut-sei=Mukherjee en-aut-mei=Piyali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BardhanMainak en-aut-sei=Bardhan en-aut-mei=Mainak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KumagaiTakanori en-aut-sei=Kumagai en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=12 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=13 ORCID= en-aut-name=KurodaTeruo en-aut-sei=Kuroda en-aut-mei=Teruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Microbiology, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Division of Bacteriology, ICMR - National Institute of Cholera and Enteric Diseases kn-affil= affil-num=3 en-affil=Division of Bacteriology, ICMR - National Institute of Cholera and Enteric Diseases kn-affil= affil-num=4 en-affil=Section of Microbial Genomics and Ecology, The IDEC Institute, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Cellular and Molecular Biology, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Cellular and Molecular Biology, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=7 en-affil=Department of Cellular and Molecular Biology, Graduate School of Biomedical and Health Sciences, Hiroshima 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=Department of Microbiology, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=11 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR-NICED kn-affil= affil-num=12 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR-NICED kn-affil= affil-num=13 en-affil=Division of Bacteriology, ICMR - National Institute of Cholera and Enteric Diseases kn-affil= affil-num=14 en-affil=Department of Microbiology, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= en-keyword=Campylobacter jejuni/coli kn-keyword=Campylobacter jejuni/coli en-keyword=whole genome sequencing kn-keyword=whole genome sequencing en-keyword=phylogenetic analysis kn-keyword=phylogenetic analysis en-keyword=plasmid structure kn-keyword=plasmid structure END start-ver=1.4 cd-journal=joma no-vol=93 cd-vols= no-issue=1 article-no= start-page=e00346-2 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=A newly developed oral infection mouse model of shigellosis for immunogenicity and protective efficacy studies of a candidate vaccine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Shigella infection poses a significant public health challenge in the developing world. However, lack of a widely available mouse model that replicates human shigellosis creates a major bottleneck to better understanding of disease pathogenesis and development of newer drugs and vaccines. BALB/c mice pre-treated with streptomycin and iron (FeCl3) plus desferrioxamine intraperitoneally followed by oral infection with virulent Shigella flexneri 2a resulted in diarrhea, loss of body weight, bacterial colonization and progressive colitis characterized by disruption of epithelial lining, loss of crypt architecture with goblet cell depletion, increased polymorphonuclear infiltration into the mucosa, submucosal swelling (edema), and raised proinflammatory cytokines and chemokines in the large intestine. To evaluate the usefulness of the model for vaccine efficacy studies, mice were immunized intranasally with a recombinant protein vaccine containing Shigella invasion protein invasion plasmid antigen B (IpaB). Vaccinated mice conferred protection against Shigella, indicating that the model is suitable for testing of vaccine candidates. To protect both Shigella and Salmonella, a chimeric recombinant vaccine (rIpaB?T2544) was developed by fusing IpaB with Salmonella outer membrane protein T2544. Vaccinated mice developed antigen-specific serum IgG and IgA antibodies and a balanced Th1/Th2 response and were protected against oral challenge with Shigella (S. flexneri 2a, Shigella dysenteriae, and Shigella sonnei) using our present mouse model and Salmonella (Salmonella Typhi and Paratyphi) using an iron overload mouse model. We describe here the development of an oral Shigella infection model in wild-type mouse. This model was successfully used to demonstrate the immunogenicity and protective efficacy of a candidate protein subunit vaccine against Shigella. en-copyright= kn-copyright= en-aut-name=HaldarRisha en-aut-sei=Haldar en-aut-mei=Risha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HalderProlay en-aut-sei=Halder en-aut-mei=Prolay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 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=5 ORCID= affil-num=1 en-affil=Division of Clinical Medicine, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=2 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=3 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=4 en-affil=Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Division of Clinical Medicine, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= en-keyword=oral route kn-keyword=oral route en-keyword=S. flexneri kn-keyword=S. flexneri en-keyword=shigellosis kn-keyword=shigellosis en-keyword=bivalent subunit vaccine (IpaB?T2544) kn-keyword=bivalent subunit vaccine (IpaB?T2544) en-keyword=mouse model kn-keyword=mouse model 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=171 cd-vols= no-issue=1 article-no= start-page=18 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Escherichia coli phages representing a distinct genus within the subfamily Stephanstirmvirinae: genome and host range characteristics en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteriophages play crucial roles in microbial ecosystems and have potential for biotechnological applications. However, our understanding of culturable phages remains limited. In this study, we characterized six novel Escherichia coli phages isolated from pig farm wastewater and urban sewage, using comprehensive genomic, morphological, and host-range analysis. Using multiple comparative approaches, including gene-sharing network analysis, average nucleotide identity (ANI), and nucleotide intergenomic similarity (NIS), we demonstrated that five of these phages form a distinct group within the subfamily Stephanstirmvirinae, potentially representing a novel genus, for which we propose the name "Wecvirus”. We further propose that these phages, each of which exhibits a unique host range pattern, should be classified in two distinct species within the proposed genus. This host specificity is reflected in differences in the amino acid sequences of tail fibers, which are crucial for infection. The remaining phage, which was not classified as a wecvirus, exhibited characteristics that challenged the current classification criteria, highlighting the need for more-flexible taxonomic approaches. These findings expand our understanding of phage diversity within the subfamily Stephanstirmvirinae and contribute to the evolving phage taxonomy framework. en-copyright= kn-copyright= en-aut-name=KanekoTomoyoshi en-aut-sei=Kaneko en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsakaToshifumi en-aut-sei=Osaka en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsunedaSatoshi en-aut-sei=Tsuneda en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Life Science and Medical Bioscience, Waseda University kn-affil= affil-num=2 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Microbiology and Immunology, Tokyo Women’s Medical University kn-affil= affil-num=4 en-affil=Department of Life Science and Medical Bioscience, Waseda University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=520 cd-vols= no-issue= article-no= start-page=41 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tunicate-specific protein Epi-1 is essential for conferring hydrophilicity to the larval tunic in the ascidian Ciona en-subtitle= kn-subtitle= en-abstract= kn-abstract=Animals must avoid adhesion to objects in the environment to maintain their mobility and independence. The marine invertebrate chordate ascidians are characterized by an acellular matrix tunic enveloping their entire body for protection and swimming. The tunic of ascidian larvae consists of a surface cuticle layer and inner matrix layer. Hydrophilic substances coat the cuticle; this modification is thought to be for preventing adhesion. However, the molecule responsible for regulating this modification has not been clarified. We here found that the tunicate-specific protein Epi-1 is responsible for preventing adhesiveness of the tunic in the ascidian Ciona intestinalis Type A. Ciona mutants with homozygous knockouts of Epi-1 exhibited adhesion to plastic plates and to other individuals. The cuticle of the Epi-1 mutants was fragile, and it lost the glycosaminoglycans supplied by test cells, the accessory cells that normally attach to the tunic surface. Although it has an apparent signal peptide for membrane trafficking, we showed that the Epi-1 protein is localized to the cytosol of the epidermal cells. Our study suggests that the emergence of the tunicate-specific protein Epi-1 made the tunic less adhesive, providing a selective advantage for the last common tunicate ancestor. en-copyright= kn-copyright= en-aut-name=KuroiwaKazu en-aut-sei=Kuroiwa en-aut-mei=Kazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Mita-YoshidaKaoru en-aut-sei=Mita-Yoshida en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HozumiAkiko en-aut-sei=Hozumi en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinoAtsuo S. en-aut-sei=Nishino en-aut-mei=Atsuo S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakuraYasunori en-aut-sei=Sasakura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=2 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=3 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=4 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=5 en-affil=Department of Biology, Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=6 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= en-keyword=Ascidian kn-keyword=Ascidian en-keyword=Ciona kn-keyword=Ciona en-keyword=Tunic kn-keyword=Tunic en-keyword=Epidermis kn-keyword=Epidermis en-keyword=Cellulose kn-keyword=Cellulose en-keyword=Glycosaminoglycan kn-keyword=Glycosaminoglycan END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=8 article-no= start-page=918 end-page=922 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240522 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Negative regulation of chitosan-induced stomatal closure by glutathione in Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chitosan (CHT) is a deacylated derivative of chitin and improves growth and yield performance, activates defensive genes, and also induces stomatal closure in plants. Glutathione (GSH) has significant functions in the growth, development, defense systems, signaling, and gene expression. GSH negatively regulates abscisic acid-, methyl jasmonate-, and salicylic acid-induced stomatal closure. However, the negative regulation by GSH of CHT-induced stomatal closure is still unknown. Regulation of CHT-induced stomatal closure by GSH in guard cells was investigated using two GSH-deficient mutants, cad2-1 and chlorina 1-1 (ch1-1), and a GSH-decreasing chemical, 1-chloro-2,4-dinitrobenzene (CDNB). The cad2-1 and ch1-1 mutations and CDNB treatment enhanced CHT-induced stomatal closure. Treatment with glutathione monoethyl ester restored the GSH level in the guard cells of cad2-1 and ch1-1 and complemented the stomatal phenotype of the mutants. These results indicate that GSH negatively regulates CHT-induced stomatal closure in Arabidopsis thaliana. en-copyright= kn-copyright= en-aut-name=JahanIsrat en-aut-sei=Jahan en-aut-mei=Israt kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=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= 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= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=chitosan kn-keyword=chitosan en-keyword=glutathione kn-keyword=glutathione en-keyword=stomatal closure kn-keyword=stomatal closure END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=7 article-no= start-page=e112232 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reappraisal of the Entity of Pediatric Uveitis: Bilateral Iridocyclitis With Retinal Capillaritis (BIRC) in Juveniles in 18 Additional Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Bilateral iridocyclitis with retinal capillaritis (BIRC) in juveniles is a newly recognized ?????entity of juvenile chronic uveitis with no systemic involvement. In this study, 18 additional consecutive patients with BIRC were reported to show that the entity would be useful in the differential diagnosis.
Methods: Clinical features were retrospectively reviewed in 18 consecutive patients diagnosed with BIRC in juveniles at Okayama University Hospital, Okayama, Japan, between 1996 and 2025.
Results: The 18 patients comprised 6 males and 12 females, with an age at onset ranging from 9 to 16 years (median, 13 years). All patients presented with aqueous cells and mutton-fat keratic precipitates in both eyes, and fluorescein angiography revealed varying degrees of optic disc leakage and retinal capillary leakage in the midperipheral to peripheral fundus of both eyes. None had systemic symptoms, including skin rashes, joint pain, or fever, and no abnormalities were detected on blood examinations, urinalysis, or plain chest x-rays. Oral prednisolone, tapered from 30 mg daily, together with topical 0.1% betamethasone four times daily, was administered to five patients: two with optic disc edema and three with macular edema in both eyes or the unilateral eye. The remaining 13 patients were treated with topical 0.1% betamethasone eye drops alone. In patients who developed elevated intraocular pressure, often due to a steroid response, the instillation of topical 0.1% betamethasone was reduced to twice daily, or intraocular pressure-lowering eye drops were used in combination. In two patients who showed relapse of unilateral macular edema after oral prednisolone was tapered or discontinued, oral colchicine (1 mg daily) was introduced, resulting in the subsidence of macular edema. Bilateral uveitis in all 18 patients subsided within 6 months to a few years until 19 years of age, and all topical medications were discontinued, with relapse occurring in only one patient.
Conclusions: BIRC in juveniles should be included in the differential diagnosis for school-age children and young adolescents. BIRC follows a chronic course of a few years and subsides completely with a good prognosis. In cases of macular edema or optic disc edema that affects vision, oral corticosteroid treatment is recommended, whereas patients with no sight-threatening signs can be treated with topical corticosteroid eye drops alone. The entity of BIRC may be distinct from juvenile chronic iridocyclitis in young girls with onset at preschool age, which shares common features with juvenile idiopathic arthritis-associated uveitis. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=bilateral iridocyclitis with retinal capillaritis (birc) kn-keyword=bilateral iridocyclitis with retinal capillaritis (birc) en-keyword=colchicine kn-keyword=colchicine en-keyword=corticosteroid kn-keyword=corticosteroid en-keyword=fluorescein angiography kn-keyword=fluorescein angiography en-keyword=juvenile kn-keyword=juvenile en-keyword=juvenile chronic iridocyclitis (jci) kn-keyword=juvenile chronic iridocyclitis (jci) en-keyword=juvenile idiopathic arthritis (jia) kn-keyword=juvenile idiopathic arthritis (jia) en-keyword=macular edema kn-keyword=macular edema en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=optic disc edema kn-keyword=optic disc edema END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=04 article-no= start-page=321 end-page=329 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and safety of endoscopic ultrasonography-guided ethanol injections of small pancreatic neuroendocrine neoplasms: a prospective multicenter study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Endoscopic ultrasonography (EUS)-guided ethanol injection (EI) has recently been introduced as one of the management strategies for pancreatic neuroendocrine neoplasms (PNENs); however, its role as a surgical alternative is unclear. We evaluated the efficacy and safety of EUS-EI in treating small PNENs through a prospective multicenter study.
Methods Patients with grade 1 tumors of ?15 mm confirmed by pathology were included. The primary end point assessed efficacy and safety, measuring complete ablation using computed tomography at 1 and 6 months, prevention of adverse events (AEs) within 1 month, severe pancreatic fistula at 1 month, and incidence/worsening of diabetes mellitus (DM) at 6 months. The composite end point of EUS-EI was compared with that of historical results of a study based on surgical treatment.
Results 25 patients with PNENs, with a median tumor size of 10.1 mm, were treated using EUS-EI. The composite primary end point was achieved by 76.0% of patients (19/25; 95%CI 54.9%?90.6%), a proportion significantly higher than that of surgical treatment (P = 0.008). Regarding efficacy, 88.0% (22/25) of patients achieved complete ablation at 1 and 6 months (95%CI 68.8%?97.5%). Regarding safety, 96.0% (24/25) of patients had no severe AEs within 1 month (95%CI 79.7%?99.9%). No patients had severe pancreatic fistulas at 1 month, and 84.0% (21/25) had no incidence or exacerbation, or both, of DM at 6 months (95%CI 63.9%?95.5%).
Conclusion EUS-EI is safe and could be a potent treatment option for patients with small PNENs. en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItoiTakao en-aut-sei=Itoi en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitanoMasayuki en-aut-sei=Kitano en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaraKazuo en-aut-sei=Hara en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwataniMasaki en-aut-sei=Kuwatani en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakenakaMamoru en-aut-sei=Takenaka en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AshidaReiko en-aut-sei=Ashida en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MukaiShuntaro en-aut-sei=Mukai en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkunoNozomi en-aut-sei=Okuno en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawakuboKazumichi en-aut-sei=Kawakubo en-aut-mei=Kazumichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SakuraiJun en-aut-sei=Sakurai en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NakatsukaYuki en-aut-sei=Nakatsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshidaMichihiro en-aut-sei=Yoshida en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Gastroenterology and Hepatology, Tokyo Medical University kn-affil= affil-num=4 en-affil=Second Department of Internal Medicine, Wakayama Medical University kn-affil= affil-num=5 en-affil=Gastroenterology, Aichi Cancer Center Hospital kn-affil= affil-num=6 en-affil=Gastroenterology and Hepatology, Hokkaido University Hospital kn-affil= affil-num=7 en-affil=Gastroenterology and Hepatology, Kindai University Faculty of Medicine Graduate School of Medical Sciences kn-affil= affil-num=8 en-affil=Second Department of Internal Medicine, Wakayama Medical University kn-affil= affil-num=9 en-affil=Gastroenterology and Hepatology, Tokyo Medical University kn-affil= affil-num=10 en-affil=Gastroenterology, Aichi Cancer Center Hospital kn-affil= affil-num=11 en-affil=Gastroenterology and Hepatology, Hokkaido University Hospital kn-affil= affil-num=12 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=14 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=16 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=16 article-no= start-page=1886 end-page=1897 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Methotrexate, Doxorubicin, and Cisplatin Versus Methotrexate, Doxorubicin, and Cisplatin + Ifosfamide in Poor Responders to Preoperative Chemotherapy for Newly Diagnosed High-Grade Osteosarcoma (JCOG0905): A Multicenter, Open-Label, Randomized Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Our previous NECO phase II studies on high-grade osteosarcoma suggested that administering ifosfamide (IF; 16 g/m2 [4g/m2 once on day 1, then 2g/m2 once on days 2-7] × six) to patients showing a poor response (PrRsp) to preoperative chemotherapy with methotrexate, doxorubicin, and cisplatin (MAP) improves their prognoses. In this Japan Clinical Oncology Group (JCOG) study, JCOG0905, we aimed to investigate the efficacy and safety of IF in patients with PrRsp.
Methods JCOG0905 is a multicenter, open-label, multi-institutional, randomized trial. Eligible patients (50 years and younger) had resectable, high-grade osteosarcoma (stage II or III, Union for International Cancer Control TNM) of the extremities, limb girdles, and thoracic wall. After two MAP cycles and tumor resection, patients with PrRsp were randomly assigned to either the MAP or MAP plus 15 g/m2 (3g/m2 once daily on days 1-5) × six IF (MAP + IF [MAPIF]) group. The primary end point was disease-free survival (DFS); secondary end points were overall survival (OS) and safety. The planned sample size was 100 patients with a one-sided α of .1 and a power of 0.7, assuming a 3-year DFS of 50% and 65% for MAP and MAPIF, respectively. This trial is registered with the Japan Registry of Clinical Trials (jRCT; jRCTs031180126).
Results Of the 287 patients registered between February 2010 and August 2020, 51 and 52 patients with PrRsp were assigned to the MAP and MAPIF groups, respectively. As of March 2022, DFS did not differ between groups (hazard ratio [HR], 1.05 [95% CI, 0.55 to 1.98]) and OS was numerically inferior in the MAPIF group (HR, 1.48 [95% CI, 0.68 to 3.22]). Nine and zero patients in the MAPIF and MAP groups discontinued treatment because of adverse events, respectively.
Conclusion Evidence from JCOG0905 does not support the addition of IF for patients with PrRsp. en-copyright= kn-copyright= en-aut-name=HiragaHiroaki en-aut-sei=Hiraga en-aut-mei=Hiroaki kn-aut-name=

in weighted space for nonlinear Schr?dinger equations below the Strauss exponent without gauge-invariance en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we consider the nonlinear Schr?dinger equation (NLS) with a general homogeneous nonlinearity in dimensions up to three. 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=100 cd-vols= no-issue=1 article-no= start-page=66 end-page=77 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Different impacts of granulocyte colony‐stimulating factor administration on allogeneic hematopoietic cell transplant outcomes for adult acute myeloid leukemia according to graft type en-subtitle= kn-subtitle= en-abstract= kn-abstract=We retrospectively evaluated the impacts of using granulocyte colony-stimulating factor (G-CSF) and its timing on posttransplant outcomes for 9766 adults with acute myeloid leukemia (AML) between 2013 and 2022 using a Japanese database. We separately evaluated three distinct cohorts based on graft type: 3248 received bone marrow transplantation (BMT), 3066 received peripheral blood stem cell transplantation (PBSCT), and 3452 received single-unit cord blood transplantation (CBT). Multivariate analysis showed that G-CSF administration significantly accelerated neutrophil recovery after BMT, PBSCT, and CBT. However, it was associated with a higher risk of grades II?IV acute graft-versus-host disease (GVHD) across all graft types. Moreover, an increased incidence of overall chronic GVHD was observed with G-CSF administration in BMT and CBT patients, but not in PBSCT patients. G-CSF administration significantly improved overall survival (OS) and leukemia-free survival (LFS) only following CBT. Regarding the timing of G-CSF, in comparison with late initiation of G-CSF (Days 5?10), early initiation (Days 0?4) did not provide benefits for hematopoietic recovery regardless of graft type. In contrast, late initiation was significantly associated with a lower risk of grades II?IV acute GVHD and better OS and LFS in CBT patients. These data demonstrated that G-CSF administration accelerated neutrophil recovery and increased the risk of grades II?IV acute GVHD across all graft types, but significantly improved survival outcomes but only following CBT. Therefore, routine use of G-CSF should be considered for CBT in adult patients with AML. en-copyright= kn-copyright= en-aut-name=KonumaTakaaki en-aut-sei=Konuma en-aut-mei=Takaaki kn-aut-name=

single-crystal elasticity of δ-AlOOH en-subtitle= kn-subtitle= en-abstract= kn-abstract=The seismic mapping of hydrous materials in the Earth’s deep interior requires experimental constraints on the elastic anisotropy of hydrous minerals and phases. Oxyhydroxides like δ-(Al,Fe)OOH are arguably the main hosts of water in the lower mantle. Therefore, constraints on the single-crystal elastic tensor of δ-(Al,Fe)OOH solid solutions are crucial to quantify the elastic anisotropy of this material, and advance the current understanding of the recycling of water into the lower mantle. Yet, experimental data for intermediate compositions are scarce, limiting the understanding of how Fe incorporation affects the single-crystal elastic properties of δ-AlOOH. In this study, we provide experimental constraints on the single-crystal elasticity of two δ-(Al,Fe)OOH solid solutions, with Fe/(Al?+?Fe) of 0.06(1) and 0.133(3). Large single-crystal samples of δ-(Al,Fe)OOH were synthetized at high pressures and temperatures using a multi-anvil press, and the full elastic stiffness tensors were determined at ambient conditions by combining X-ray diffraction and Brillouin scattering measurements. We show that replacing Al3+ with Fe3+ in δ-(Al,Fe)OOH lowers the magnitude of most coefficients of the elastic stiffness tensor (cij), which translates into a substantial reduction of aggregate moduli and acoustic wave velocities. We further show that, at ambient conditions, the acoustic anisotropy of δ-(Al,Fe)OOH displays no sensitivity to Fe?Al substitution. en-copyright= kn-copyright= en-aut-name=SattaNiccol? en-aut-sei=Satta en-aut-mei=Niccol? kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CrinitiGiacomo en-aut-sei=Criniti en-aut-mei=Giacomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Boffa BallaranTiziana en-aut-sei=Boffa Ballaran en-aut-mei=Tiziana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KurnosovAlexander en-aut-sei=Kurnosov en-aut-mei=Alexander kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BuchenJohannes en-aut-sei=Buchen en-aut-mei=Johannes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MarquardtHauke en-aut-sei=Marquardt en-aut-mei=Hauke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institut f?r Mineralogie, Universit?t M?nster kn-affil= affil-num=2 en-affil=Bayerisches Geoinstitut, Universit?t Bayreuth kn-affil= affil-num=3 en-affil=Bayerisches Geoinstitut, Universit?t Bayreuth kn-affil= affil-num=4 en-affil=Bayerisches Geoinstitut, Universit?t Bayreuth kn-affil= affil-num=5 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=6 en-affil=Bayerisches Geoinstitut, Universit?t Bayreuth kn-affil= affil-num=7 en-affil=Department of Earth Sciences, University of Oxford kn-affil= en-keyword=Elasticity kn-keyword=Elasticity en-keyword=δ-AlOOH kn-keyword=δ-AlOOH en-keyword=Water kn-keyword=Water en-keyword=Anisotropy kn-keyword=Anisotropy en-keyword=Solid solutions kn-keyword=Solid solutions en-keyword=Brillouin scattering kn-keyword=Brillouin scattering END start-ver=1.4 cd-journal=joma no-vol=361 cd-vols= no-issue= article-no= start-page=107331 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of chemistry on the compressibility and high-pressure structural evolution of the CaFe2O4-type aluminous silicate phase en-subtitle= kn-subtitle= en-abstract= kn-abstract=Approximately 22?26 vol% of a basaltic phase assemblage at lower mantle conditions is comprised of a (Na,Mg,Fe2+)(Al,Si,Fe3+)2O4 phase with CaFe2O4-type (CF-type) structure. Previous experimental studies attempted to determine the equation of state of the CF-type phase but reported contrasting compressibility values, even for samples with the same composition. Therefore, the elastic properties of the CF-type phase remain, to date, largely unconstrained. Here, we conducted single-crystal X-ray diffraction (SCXRD) measurements in the diamond anvil cell (DAC) at high pressure and room temperature on three samples of CF-type phase with compositions Na0.90(1)Al1.03(2)Si1.00(2)O4 (NaCF), Na0.66(4)Mg0.28(4)Al1.22(3)Si0.78(3)O4 (MgCF) and Na0.62(2)Mg0.19(1)Fe2+0.17(1)Fe3+0.080(4)Al1.20(3)Si0.70(1)O4 (FeCF). A multi-sample loading approach was employed for most DAC runs, where two samples were loaded in the same sample chamber to reduce possible systematic deviations between datasets, thus enhancing internal consistency and corroborating data reproducibility. Experiments on the NaCF and MgCF samples were conducted up to ?50 GPa, while the FeCF sample was compressed to ?72 GPa to better characterize the effect of the spin crossover of octahedrally coordinated Fe3+. We found the isothermal bulk modulus (KT0) to increase with decreasing NaAlSiO4 content, accompanied by only a slight decrease in its pressure derivative (K'T0). Analysis of the crystal structures of the three samples at high pressure allowed compositional trends to be determined also for the interatomic bonds and polyhedral compressibility, as well as the distortion indices. These suggest an overall stiffening of the A site with increasing Mg2+ and Fe2+ content, as well of the two B sites with increasing Al3+ and Fe3+ content. Enhanced compressibility of the unit cell and octahedral B sites was observed between ?26?42 GPa in the FeCF sample, suggesting a pressure-induced spin crossover of Fe3+, in agreement with some previous observations. Finally, trends in the elastic properties from experimental studies conducted along the NaAlSiO4-MgAl2O4 join are discussed and used as a proxy to evaluate the reliability of end-member properties for the CF-type phase employed in most recent mineral physical and thermodynamic databases. Our analysis suggests current mineral physical models might underestimate densities and overestimate bulk sound velocities of NaAlSiO4-rich CF-type phases with basaltic composition. en-copyright= kn-copyright= en-aut-name=CrinitiGiacomo en-aut-sei=Criniti en-aut-mei=Giacomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Boffa BallaranTiziana en-aut-sei=Boffa Ballaran en-aut-mei=Tiziana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurnosovAlexander en-aut-sei=Kurnosov en-aut-mei=Alexander kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RogmannElena-Marie en-aut-sei=Rogmann en-aut-mei=Elena-Marie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GlazyrinKonstantin en-aut-sei=Glazyrin en-aut-mei=Konstantin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FedotenkoTimofey en-aut-sei=Fedotenko en-aut-mei=Timofey kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FrostDaniel J. en-aut-sei=Frost en-aut-mei=Daniel J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= affil-num=2 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= affil-num=3 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= affil-num=4 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=5 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= affil-num=6 en-affil=Deutsches Elektronen-Synchrotron DESY kn-affil= affil-num=7 en-affil=Deutsches Elektronen-Synchrotron DESY kn-affil= affil-num=8 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= en-keyword=CaFe2O4-type phase kn-keyword=CaFe2O4-type phase en-keyword=Lower mantle kn-keyword=Lower mantle en-keyword=Equations of state kn-keyword=Equations of state en-keyword=Structural refinements kn-keyword=Structural refinements en-keyword=Crystal chemistry kn-keyword=Crystal chemistry en-keyword=Fe3+ spin-crossover kn-keyword=Fe3+ spin-crossover END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=12 article-no= start-page=3282 end-page=3304 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241027 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Radial transport and nebular thermal processing of millimeter‐sized solids in the Solar protoplanetary disk inferred from Cr‐Ti‐O isotope systematics of chondrules en-subtitle= kn-subtitle= en-abstract= kn-abstract=Understanding the material transport and mixing processes in the Solar protoplanetary disk provides important constraints on the origin of chemical and isotopic diversities of our planets. The limited extent of radial transport and mixing between the inner and outer Solar System has been suggested based on a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC) meteorite groups. The limited transport and mixing could be further tested by tracing the formation regions of individual meteoritic components, such as Ca-Al-rich inclusions (CAIs) and chondrules. Here, we show further evidence for the outward transport of CAIs and chondrules from the inner and subsequent thermal processing in the outer region of the protoplanetary disk based on the petrography and combined Cr-Ti-O isotope systematics of chondrules from the Vigarano-like (CV) carbonaceous chondrite Allende. One chondrule studied consists of an olivine core that exhibits NC-like Ti and O, but CC-like Cr isotopic signatures, which is enclosed by a pyroxene igneous rim with CC-like O isotope ratios. These observations indicate that the olivine core formed in the inner Solar System. The olivine core then migrated into the outer Solar System and experienced nebular thermal processing that generated the pyroxene igneous rim. The nebular thermal processing would result in Cr isotope exchange between the olivine core and CC-like materials, but secondary alteration effects on the parent body are also responsible for the CC-like Cr isotope signature. By combining previously reported Cr-Ti-O isotope systematics of CV chondrules, we show that some CV chondrules larger than ~1?mm would have formed in the inner Solar System. The accretion of the millimeter-sized, inner Solar System solids onto the CV carbonaceous chondrite parent body would require their very early migration into the outer Solar System within the first 1 million years after the Solar System formation. en-copyright= kn-copyright= en-aut-name=FukudaKohei en-aut-sei=Fukuda en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HibiyaYuki en-aut-sei=Hibiya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KastelleCraig R. en-aut-sei=Kastelle en-aut-mei=Craig R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiKatsuhiko en-aut-sei=Suzuki en-aut-mei=Katsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IizukaTsuyoshi en-aut-sei=Iizuka en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamashitaKatsuyuki en-aut-sei=Yamashita en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HelserThomas E. en-aut-sei=Helser en-aut-mei=Thomas E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KitaNoriko T. en-aut-sei=Kita en-aut-mei=Noriko T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=WiscSIMS, Department of Geoscience, University of Wisconsin-Madison kn-affil= affil-num=2 en-affil=Research Center for Advanced Science and Technology, Graduate School of Science, The University of Tokyo kn-affil= affil-num=3 en-affil=National Oceanic and Atmospheric Administration kn-affil= affil-num=4 en-affil=Submarine Resources Research Center, Japan Agency for Marine-Earth Science Technology kn-affil= affil-num=5 en-affil=Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=National Oceanic and Atmospheric Administration kn-affil= affil-num=8 en-affil=WiscSIMS, Department of Geoscience, University of Wisconsin-Madison kn-affil= END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=3 article-no= start-page=497 end-page=503 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Five-year outcomes with gefitinib induction and chemoradiotherapy in EGFR-mutant stage III non-small-cell lung cancer: LOGIK0902/OLCSG0905 phase II study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background We previously showed the 2-year OS rate, the primary endpoint, of 90% in a phase II trial of gefitinib induction followed by chemoradiotherapy (CRT) in unresectable, stage III, EGFR-mutant, non-small-cell lung cancer (NSCLC). However, neither long-term survival data nor late-phase adverse event profiles have been presented.
Patients and methods Patients with unresectable, EGFR-mutant, stage III NSCLC were administered gefitinib monotherapy for 8 weeks. After confirming no disease progression during induction therapy, cisplatin and docetaxel on days 1, 8, 29, and 36 with concurrent radiotherapy at a total dose of 60 Gy were subsequently administered.
Results In the enrolled twenty patients, the 5-year OS rate and median survival time were 70.0% [95% confidence interval: 45.1?85.3] and 5.5 years [4.91-NE], respectively, whereas 5-year PFS rate and median PFS time were 15.0% (3.7?33.5) and 1.4 years [0.69?2.29], respectively. Efficacy did not seem influenced even if radiation field was re-planed in response to the effect of gefitinib induction. As for late adverse events, pulmonary fibrosis occurred in 7 patients (35%). The median time from completion of CRT to the occurrence of the event was 245 days. All were grade 1, and there was no evidence of cavitation of the lesions or chronic infections such as Aspergillus infection during the course of the disease. One case of small cell lung cancer occurred during the period.
Conclusions With longer follow-up time, we demonstrated favorable efficacy with tolerable toxicity profiles in the EGFR-TKI induction followed by standard CRT in EGFR-mutant, stage III, NSCLC.

It is first shown that identical vanishing of the Wronskian leads to two different representations of vector-valued functions that lie in the null space of the Wronski matrix. It is further shown that they are algebraically linearly dependent, by which we are immediately led to a key identity in the Wronskian theory, derived only through very simple linear algebraic arguments. Most fundamental results on the Wronskian theory available in the literature can thus be obtained in a quite straightforward fashion with a very clear perspective, and hence the relevant arguments are believed to be of pedagogical value, too. Some further issues relevant to the null space viewpoint are also discussed, where some other results available in the literature are derived through the null space viewpoint in a somewhat strengthened form. en-copyright= kn-copyright= en-aut-name=HagiwaraTomomichi en-aut-sei=Hagiwara en-aut-mei=Tomomichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Electrical Engineering Graduate School of Engineering Kyoto University kn-affil= en-keyword=linear independence of functions kn-keyword=linear independence of functions en-keyword=Wronski matrix kn-keyword=Wronski matrix en-keyword=eigenspace kn-keyword=eigenspace en-keyword=determinants kn-keyword=determinants en-keyword=minors kn-keyword=minors END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=139 end-page=146 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=Matijevic-Roberts type theorems, Rees rings and associated graded rings en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this article is to investigate interrelated structures lying among three notable problems in commutative algebra.

When the multipointed d-space realizes a precubical set, its reflection coincides with the standard realization of the precubical set as a directed space. The reflection enables us to extend the construction of the natural system of topological spaces in Baues-Wirsching’s sense from directed spaces to multipointed d-spaces. In the case of a cellular multipointed d-space, there is a discrete version of this natural system which is proved to be bisimilar up to homotopy. We also prove that these constructions are invariant up to homotopy under globular subdivision. These results are the globular analogue of Dubut’s results. Finally, we point the apparent incompatibility between the notion of bisimilar natural systems and the q-model structure of multipointed d-spaces and we give some suggestions for future works. en-copyright= kn-copyright= en-aut-name=GaucherPhilippe en-aut-sei=Gaucher en-aut-mei=Philippe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Universit?

Traditional methods, such as the 6-min walk test or patient-reported questionnaires can be burdensome, or may not accurately reflect recovery. Accelerometer-based measurement provides a low-burden, objective approach, but previous studies focused on the immediate postoperative period or long after discharge, leaving the recovery trajectory from surgery to discharge underexplored. en-copyright= kn-copyright= en-aut-name=YamaneTakahiro en-aut-sei=Yamane en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraYoshikazu en-aut-sei=Kimura en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TetsutaniManami en-aut-sei=Tetsutani en-aut-mei=Manami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamuraShota en-aut-sei=Yamamura en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItoAiru en-aut-sei=Ito en-aut-mei=Airu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanumaMoe en-aut-sei=Tanuma en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HonjohMina en-aut-sei=Honjoh en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriwakiYoshiko en-aut-sei=Moriwaki en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsuokaYoshikazu en-aut-sei=Matsuoka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Biomedical Informatics, Okayama University Graduate School of Interdisciplinary Science and Engineering in Health Systems kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=4 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=5 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=6 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Biomedical Informatics, Okayama University Graduate School of Interdisciplinary Science and Engineering in Health Systems kn-affil= affil-num=14 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=actigraphy kn-keyword=actigraphy en-keyword=esophageal cancer kn-keyword=esophageal cancer en-keyword=monitoring indicator kn-keyword=monitoring indicator en-keyword=physical activity kn-keyword=physical activity en-keyword=postoperative recovery kn-keyword=postoperative recovery en-keyword=surgery‐to‐discharge kn-keyword=surgery‐to‐discharge END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=5 article-no= start-page=1142 end-page=1155.e6 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=Compound starch granule formation in grass seeds is associated with distinct temporal patterns of gene expression en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is extensive interspecies variation in starch granule morphology in the endosperm of grass species, but the factors underpinning this variation are poorly understood. The two major granule morphology types among species are simple and compound granules, where simple granules arise from a single initiation per amyloplast, and compound granules form from multiple granule initiations. Here, we carried out an extensive survey of seed starch morphology, examining specimens from 105 species within the Pooideae using electron microscopy. This not only expanded our current knowledge of the diversity of starch granule types but also confirmed the homoplasy of simple and compound starch granules. We then selected species representing independent origins of simple (Brachyelytrum japonicum, Phaenosperma globosa, and Brachypodium distachyon) and compound granules (Nardus stricta, Melica altissima, and Calamagrostis brachytricha) for analysis of starch structure and gene expression. There were no clear patterns in starch content, amylopectin structure, or amylose content that could distinguish the two granule types. However, comparative transcriptomics over seed development revealed gene expression patterns associated with granule type, most notably increasing expression of STARCH SYNTHASE 3a (SS3a), STARCH BRANCHING ENZYME 1 (SBE1), and limit dextrinases (LDAs) between 3 and 9 days post anthesis in species with compound granules. Mutation of these genes in rice, which natively produces compound granules, resulted in altered granule shape and/or size. Our work highlights differences in gene expression that could contribute to natural variation in granule morphology within the Pooideae while providing important new starch phenotype and gene expression datasets that can be widely used to study endosperm development. en-copyright= kn-copyright= en-aut-name=Watson-LazowskiAlexander en-aut-sei=Watson-Lazowski en-aut-mei=Alexander kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FeikeDoreen en-aut-sei=Feike en-aut-mei=Doreen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NgaiQi Yang en-aut-sei=Ngai en-aut-mei=Qi Yang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EschLara en-aut-sei=Esch en-aut-mei=Lara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujitaNaoko en-aut-sei=Fujita en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsushimaRyo en-aut-sei=Matsushima en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SmithAlison M. en-aut-sei=Smith en-aut-mei=Alison M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SeungDavid en-aut-sei=Seung en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=2 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=3 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=4 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=5 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=8 en-affil=John Innes Centre, Norwich Research Park kn-affil= en-keyword=amylopectin kn-keyword=amylopectin en-keyword=amylose kn-keyword=amylose en-keyword=endosperm kn-keyword=endosperm en-keyword=grasses kn-keyword=grasses en-keyword=starch kn-keyword=starch en-keyword=starch granule kn-keyword=starch granule en-keyword=transcriptomics kn-keyword=transcriptomics END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=11 article-no= start-page=8183 end-page=8197 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Solution Structure and Counterion Condensation of Carboxymethyl Cellulose in Organic Solvents en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report scattering (SANS and SAXS) and electrical conductivity data for aqueous and organic solutions of carboxymethyl cellulose with tetrabutylammonium counterions. For SANS in deuterated solvents, the contrast is heavily dominated by the hydrogen-rich counterions, while for SAXS the polymer backbone has a more significant contribution to the scattering signal. The correlation length calculated from the SAXS measurements follows a scaling law of ξ ∝ c?1/2, while that measured by SANS displays a weaker exponent at higher concentrations for solvents of high dielectric constants. These results indicate a decoupling in the characteristic length scales of fluctuations of the polymer backbone and counterions at high polyelectrolyte concentrations. The stretching parameter calculated from the correlation length indicates a highly stretched local conformation for TBACMC in water and several high dielectric constant solvents, consistent with the semiflexible nature of the cellulose backbone. In solvents of lower dielectric permittivity, the chains display a higher degree of local coiling. Combining electrical conductivity and scattering data, we find that the fraction of monomers bearing a dissociated charge is nearly independent of concentration and approximately proportional to the reciprocal of the Bjerrum length of the solvent, as expected by the Oosawa-Manning model. en-copyright= kn-copyright= en-aut-name=GulatiAnish en-aut-sei=Gulati en-aut-mei=Anish kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MengLingzi en-aut-sei=Meng en-aut-mei=Lingzi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HouCan en-aut-sei=Hou en-aut-mei=Can kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LopezCarlos G. en-aut-sei=Lopez en-aut-mei=Carlos G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Physical Chemistry, RWTH Aachen University kn-affil= affil-num=2 en-affil=Materials Science and Engineering Department, The Pennsylvania State University kn-affil= affil-num=3 en-affil=Institute of Physical Chemistry, RWTH Aachen University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Materials Science and Engineering Department, The Pennsylvania State University kn-affil= en-keyword=polyelectrolyte kn-keyword=polyelectrolyte en-keyword=scattering kn-keyword=scattering en-keyword=conductivity kn-keyword=conductivity en-keyword=cellulose kn-keyword=cellulose en-keyword=condensation kn-keyword=condensation END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=69 end-page=77 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=加齢に係る変化意識，主観的幸福感，心理的ストレスの関連 kn-title=Relationships between awareness of age-related change, subjective well-being, and psychological stress en-subtitle= kn-subtitle= en-abstract= kn-abstract=本研究は、加齢に伴う変化の認識（Awareness of Age-Related Change: AARC）、主観的幸福感（Subjective Well-Being:SWB）、および心理的ストレスの縦断的関係の検討を行った。AARC は、ライフスパン発達理論に基づき、心理的適応に重要な役割を果たすとされる。先行研究ではAARC 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 en-aut-mei=Natsue kn-aut-name=白石 奈津栄 kn-aut-sei=白石 kn-aut-mei=奈津栄 aut-affil-num=1 ORCID= en-aut-name=BrothersAllyson en-aut-sei=Brothers en-aut-mei=Allyson kn-aut-name=ブラザーズ アリソン kn-aut-sei=ブラザーズ kn-aut-mei=アリソン aut-affil-num=2 ORCID= en-aut-name=YamamotoYasuhiro en-aut-sei=Yamamoto en-aut-mei=Yasuhiro kn-aut-name=山本 康裕 kn-aut-sei=山本 kn-aut-mei=康裕 aut-affil-num=3 ORCID= en-aut-name=NakagawaTakeshi en-aut-sei=Nakagawa en-aut-mei=Takeshi kn-aut-name=中川 威 kn-aut-sei=中川 kn-aut-mei=威 aut-affil-num=4 ORCID= en-aut-name=HoriuchiTakashi en-aut-sei=Horiuchi en-aut-mei=Takashi kn-aut-name=堀内 孝 kn-aut-sei=堀内 kn-aut-mei=孝 aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Social and Cultural Sciences, Okayama University kn-affil=岡山大学 大学院社会文化科学研究科 affil-num=2 en-affil=Human Development and Family Studies, Colorado State University kn-affil=コロラド州立大学 人間発達・家族学科 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 affil-num=4 en-affil=Graduate School of Human Sciences, University of Osaka kn-affil=大阪大学 大学院人間科学研究科 affil-num=5 en-affil=Faculty of Humanities and Social Sciences, Okayama University kn-affil=岡山大学 学術研究院社会文化科学学域 en-keyword=subjective well-being kn-keyword=subjective well-being en-keyword=psychological stress kn-keyword=psychological stress en-keyword=subjective agings kn-keyword=subjective agings en-keyword=awareness of age-related change kn-keyword=awareness of age-related change en-keyword=life satisfaction kn-keyword=life satisfaction END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=1866 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Grain boundary diffusion cannot explain the W isotope heterogeneities of the deep mantle en-subtitle= kn-subtitle= en-abstract= kn-abstract=The low 182W/184W and high 3He/4He in some ocean island basalts compared to the bulk mantle values may derive from the Earth’s core through long-term core-mantle interactions.

Here we show that the diffusion of W is sluggish under core-mantle boundary conditions, and thus is unlikely to have observable impacts on the W isotopic compositions of terrestrial igneous rocks. en-copyright= kn-copyright= en-aut-name=PengYihang en-aut-sei=Peng en-aut-mei=Yihang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=DengJie en-aut-sei=Deng en-aut-mei=Jie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Geosciences, Princeton University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Department of Geosciences, Princeton University kn-affil= END
