Early psychiatric evaluation in the ED can help reduce repeated self-harm; however, the relationship between presentation timing and psychiatric consultations remains unclear. This study aimed to explore the association between ED visit timing and the likelihood of psychiatric referrals among patients presenting with self-harm or suicide attempts in Japan.
Methods This multicenter, registry-based cohort study analyzed data from the JAPAN Registry of Self-Harm and Suicide Attempt from December 1, 2022, to December 31, 2023. Patients presenting to EDs with intentional self-harm or suicide attempts were included. The primary outcome was psychiatric consultation within one day of presentation, analyzed by day and time of presentation using multiple logistic regression, adjusting for potential confounders.
Results Of the 1,721 patients analyzed, the median age was 33 years, and 1,127 (65.5%) were female. A total of 1,199 patients (69.7%) received psychiatric consultations, while 522 (30.3%) did not receive a consultation within the next day after presentation. Hospital presentations on Saturdays (adjusted OR, 0.39; 95% CI, 0.20?0.75) and during 4 p.m. to 8 p.m. (adjusted OR, 0.47; 95% CI, 0.24?0.91) were associated with lower likelihoods of psychiatric consultations, using Monday and the 8 a.m. to 12 p.m. period as the reference, respectively.
Conclusions Hospital presentations on Saturdays or evening hours were associated with reduced likelihoods of psychiatric consultations, highlighting disparities in access to care during off-hours. These findings may help inform efforts to improve resource allocation and flexible staffing to ensure timely and consistent psychiatric care in ED settings.

Perioperative immunotherapy has become the standard of care in patients with high-risk muscle-invasive urothelial carcinoma (MIUC). This study aimed to clarify oncological outcomes and safety profiles of adjuvant nivolumab therapy in MIUC, focusing on upper tract urothelial carcinoma (UTUC).
Methods
This multicenter study comprised 97 patients undergoing removal of primary tumors, followed by adjuvant nivolumab therapy with a potential follow-up period ??12?months. Patients were divided according to the primary tumor location: bladder cancer (BC), n?=?66 (68%); UTUC, n?=?31 (32%). Multivariable Cox regression analyses were applied to identify prognostic factors for disease-free survival (DFS).
Results
Before surgery, 38% of patients had an estimated glomerular filtration rate (eGFR)? Conclusions
Adjuvant nivolumab therapy may provide comparable oncological outcomes between BC and UTUC. Baseline eosinophil count was an independent prognosticator for DFS. The incidences of adrenal insufficiency and hypophysitis appeared higher in our real-world data. Clinicians should recognize these irAEs due to nonspecific symptoms and considerable variability in time of onset. en-copyright= kn-copyright= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama

Perfusion and CLAD]Free Survival After Single Lung Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The physiological relevance of postoperative perfusion distribution after single lung transplantation (SLT) remains poorly defined, as asymmetric blood flow toward the graft is often regarded as an inherent consequence of the remaining native lung. This study aimed to determine whether the graft-directed perfusion ratio assessed by quantitative lung perfusion scintigraphy (QLPS) in the early postoperative period serves as an early physiological marker after SLT.
Methods
We retrospectively analyzed SLT recipients who underwent surgery at Okayama University Hospital between 1998 and 2021 and completed QLPS approximately 3?months posttransplant. The graft perfusion ratio (graft flow/total pulmonary flow ~ 100%) was quantified, and recipients were classified into high (??80%) and low ( Results
Recipients with higher graft perfusion demonstrated significantly better CLAD-free survival (p = 0.027). Overall survival was higher in the high-perfusion group, although the difference did not reach statistical significance (p = 0.075). Repeated-measures ANOVA revealed a significant group-by-time interaction (p = 0.019): recipients who developed CLAD had lower graft perfusion as early as 3?months after transplantation, followed by a progressive decline, whereas those who did not develop CLAD maintained stable perfusion. In the multivariable Cox analysis, higher graft perfusion was associated with a lower hazard of reaching the composite CLAD-free survival endpoint.
Conclusions
Early postoperative graft perfusion assessed by QLPS may serve as a noninvasive physiological marker after SLT. Higher graft-directed perfusion was associated with a lower hazard of reaching the composite CLAD-free survival endpoint and may aid early risk stratification and posttransplant surveillance. en-copyright= kn-copyright= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiharaMegumi en-aut-sei=Ishihara en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuboYujiro en-aut-sei=Kubo en-aut-mei=Yujiro 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=NakajimaKumi en-aut-sei=Nakajima en-aut-mei=Kumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TorigoeHidejiro en-aut-sei=Torigoe en-aut-mei=Hidejiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 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=12 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=13 ORCID= affil-num=1 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery and Lung Transplantation, Hospital Universitario Puerta de Hierro-Majadahonda kn-affil= affil-num=4 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of General Thoracic, Breast, and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic lung allograft dysfunction kn-keyword=chronic lung allograft dysfunction en-keyword=perfusion scintigraphy kn-keyword=perfusion scintigraphy en-keyword=single lung transplantation kn-keyword=single lung transplantation 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=20261024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robots for CT-guided needle insertion: clinical implementation and future perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Robotic systems for computed tomography (CT)-guided needle insertion have been developed to address the limitations of conventional manual needle insertion. Thus far, various robotic systems have been clinically implemented, and accumulating evidence has suggested their clinical utility. The evidence has evolved beyond initial feasibility and early clinical experience to include larger observational and comparative studies. These studies have demonstrated high success rates of robot-assisted needle insertion in various CT-guided interventions, including thermal ablation, biopsy, and preoperative localization. Furthermore, an increasing number of comparative studies have demonstrated the advantages of robot-assisted procedures over conventional manual procedures. These advantages include improved needle insertion accuracy and reduced radiation doses to patients and/or physicians. Although most currently available robotic systems are needle-guiding robots designed to align a needle guide with a predetermined insertion trajectory, we have developed a CT-guided needle insertion robot capable of robotic needle advancement via remote control. Clinical studies have demonstrated the feasibility of robotic needle insertion using this system, as well as needle placement accuracy comparable to that of manual procedures, while eliminating radiation exposure to physicians. The integration of artificial intelligence and the implementation of telerobotic interventions are expected to contribute significantly to the further advancement of robotic systems for CT-guided needle insertion. This narrative review summarizes the current clinical implementations and available evidence for robotic systems for CT-guided needle insertion, including our system, and discusses future perspectives in this field. en-copyright= kn-copyright= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraYuta en-aut-sei=Kimura en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsunoTakayuki en-aut-sei=Matsuno en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Robot kn-keyword=Robot en-keyword=CT-guided kn-keyword=CT-guided en-keyword=Needle kn-keyword=Needle en-keyword= Intervention kn-keyword= Intervention en-keyword= Artificial intelligence kn-keyword= Artificial intelligence en-keyword=Telerobotics kn-keyword=Telerobotics 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=317 end-page=325 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=Radiogenomic Analysis of Contrast-Enhanced MRI for Predicting Pathogenic BRCA Variants in Ovarian Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study evaluated the feasibility of predicting pathogenic BRCA1/2 variants in ovarian cancer using radiogenomic analysis of contrast-enhanced MRI. Twenty six patients were analyzed, including 14 with pathogenic BRCA1/2 variants and 12 without. Contrast enhanced MRI was used to generate two dimensional (2D) and three dimensional (3D) tumor segmentations. Radiomic features extracted with PyRadiomics were reduced using least absolute shrinkage and selection operator (LASSO) regression, yielding two selected features. Linear discriminant analysis (LDA) models were trained on 18 patients and tested on 8, with performance assessed using sensitivity, specificity, accuracy, and the area under the receiver operating characteristic (ROC) curve. The DeLong test compared AUCs between segmentation methods. Automated machine learning (AutoML) was performed with a training set of 20 patients and a test set of 6, with multiple performance metrics calculated. LDA achieved approximately 60% accuracy in both 2D and 3D test datasets. AUCs were 0.80 (3D) and 0.77 (2D), with no significant difference (p=0.85). AutoML identified CatBoost_BAG_L2_FULL as the optimal model, achieving accuracy above 80%. MRI-based radiogenomic analysis demonstrated moderate classification performance for identifying pathogenic BRCA1/2 variants in ovarian cancer. These preliminary findings suggest a potential role for noninvasive prediction, warranting further validation in larger cohorts. en-copyright= kn-copyright= en-aut-name=SaitoHayato en-aut-sei=Saito en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuiRyohei en-aut-sei=Fukui en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TadaAkihiro en-aut-sei=Tada en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=4 en-affil=Okayama Diagnostic Imaging Center kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= en-keyword=ovarian cancer kn-keyword=ovarian cancer en-keyword=BRCA1/2 kn-keyword=BRCA1/2 en-keyword=radiogenomics kn-keyword=radiogenomics en-keyword=machine learning kn-keyword=machine learning en-keyword=MRI kn-keyword=MRI 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.

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=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. This review summarizes the current evidence on AI-assisted POCS, discusses practical considerations for clinical translation, and highlights future directions, including real-time integration and multimodal decision support. en-copyright= kn-copyright= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=peroral cholangioscopy kn-keyword=peroral cholangioscopy en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=biliary stricture kn-keyword=biliary stricture en-keyword=deep learning kn-keyword=deep learning en-keyword=virtual chromoendoscopy kn-keyword=virtual chromoendoscopy END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=10 article-no= start-page=533 end-page=547 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=Integration of QSAR modeling and in vitro validation for identification of food-derived Nrf2 activators against arsenic-induced toxicity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Arsenic exposure is a major public health concern due to its toxicity and carcinogenicity, largely mediated by oxidative stress, and activation of the Nrf2 signaling pathway is considered a promising strategy to mitigate such damage. In this study, a quantitative structure?activity relationship (QSAR) model was developed to identify potential Nrf2 activators from food-derived compounds. Machine learning algorithms, including Random Forest (RF), Support Vector Machine (SVM), Linear Discriminant Analysis (LDA), and a stacking model, were developed and optimized. The optimized RF, SVM, and LDA models were subsequently integrated into a stacking framework, which was selected as the final predictive model for virtual screening based on its robust and balanced predictive performance. The stacking model achieved the highest accuracy during five-fold cross-validation (0.77) and demonstrated competitive performance on the independent test set (0.742 } 0.040), with balanced precision, sensitivity, and F-measure. Consequently, the stacking model was selected as the final model for virtual screening. A total of 70,926 compounds retrieved from a food-derived database were filtered based on physicochemical criteria, and QSAR-based virtual screening predicted 920 compounds as potential activators of the Nrf2 signaling pathway, from which 5,7-Dimethylchrysin (FooDB ID: FDB015537) and Demethylvestitol (FooDB ID: FDB012218) were selected for experimental validation. In vitro assays using HepG2 cells demonstrated that 5,7-Dimethylchrysin significantly enhanced cell viability against sodium arsenite (150 ƒÊM)-induced cytotoxicity, with an effective concentration (EC50) of 0.54 ƒÊM, whereas Demethylvestitol exhibited only limited protective effects. Furthermore, luciferase reporter assays confirmed that 5,7-Dimethylchrysin activated antioxidant response element (ARE)-driven transcription in a concentration-dependent manner, producing a 1.5 to 2.4-fold increase at concentrations ranging from 0.78 to 6.25 ƒÊM. Overall, these findings highlight the effectiveness of integrating QSAR modeling with experimental validation to identify food-derived compounds with protective potential against arsenic-induced toxicity, with 5,7-Dimethylchrysin emerging as a promising candidate for further investigation. en-copyright= kn-copyright= en-aut-name=HuongNgo Thanh en-aut-sei=Huong en-aut-mei=Ngo Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KodamaSusumu en-aut-sei=Kodama en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoAtsushi en-aut-sei=Ono en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Laboratory of Toxicology, Division of Pharmaceutical Sciences, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Toxicology, Division of Pharmaceutical Sciences, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Toxicology, Division of Pharmaceutical Sciences, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Arsenic toxicity kn-keyword=Arsenic toxicity en-keyword=Nrf2 activator kn-keyword=Nrf2 activator en-keyword=QSAR modeling kn-keyword=QSAR modeling en-keyword=Food-derived compounds kn-keyword=Food-derived compounds en-keyword=In vitro kn-keyword=In vitro END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=10 article-no= start-page=1697 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20261010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Purification, Structural Characterization, and Genomic Insights of an Anti-MRSA Peptide from Mangrove-Derived Brevibacillus sp. A34 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The widespread prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in community and healthcare settings has driven the urgent search for novel antibacterial agents. Mangrove sediments are an underexplored source of antimicrobial-producing bacteria. This study characterized an antimicrobial fraction and the genome of the mangrove-derived isolate Brevibacillus sp. A34. The active fraction was purified via ammonium sulfate precipitation, cation-exchange chromatography, and reversed-phase chromatography. De novo MS/MS analysis assigned the octapeptide LLLLLLAH (905.19 Da), designated as A34 AMP, which was further confirmed by chemical synthesis. This active peptide inhibited all four tested S. aureus strains, including three MRSA strains, with a minimum inhibitory concentration (MIC) of 62 ?g/mL. At 2~ and 4~ MIC, A34 AMP exhibited a concentration-dependent bactericidal effect within 20 h. Increased SYTOX Green uptake and morphological alterations supported a membrane permeabilization mechanism, and antimicrobial activity was retained following thermal, pH, protease, and surfactant treatments. Genome mining identified 23 putative biosynthetic gene clusters, including an 11-module nonribosomal peptide synthetase (NRPS) cluster linked to A34 AMP through three-dimensional adenylation-domain modeling. Collectively, these findings highlight A34 AMP from Brevibacillus sp. A34 as a promising bioactive anti-staphylococcal peptide scaffold. en-copyright= kn-copyright= en-aut-name=ThonginThanyamai en-aut-sei=Thongin en-aut-mei=Thanyamai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SermkaewNamfa en-aut-sei=Sermkaew en-aut-mei=Namfa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AtipairinApichart en-aut-sei=Atipairin en-aut-mei=Apichart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KrobthongSucheewin en-aut-sei=Krobthong en-aut-mei=Sucheewin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AonbangkhenChanat en-aut-sei=Aonbangkhen en-aut-mei=Chanat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=SongnakaNuttapon en-aut-sei=Songnaka en-aut-mei=Nuttapon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=School of Pharmacy, Walailak University kn-affil= affil-num=2 en-affil=School of Pharmacy, Walailak University kn-affil= affil-num=3 en-affil=School of Pharmacy, Walailak University kn-affil= affil-num=4 en-affil=Center of Excellence in Natural Products Chemistry (CENP), Department of Chemistry, Faculty of Science, Chulalongkorn University kn-affil= affil-num=5 en-affil=Center of Excellence in Natural Products Chemistry (CENP), Department of Chemistry, Faculty of Science, Chulalongkorn University kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama 700-8558, Japan kn-affil= affil-num=7 en-affil=School of Pharmacy, Walailak University kn-affil= en-keyword=Brevibacillus sp. kn-keyword=Brevibacillus sp. en-keyword=antimicrobial peptide kn-keyword=antimicrobial peptide en-keyword=AMP kn-keyword=AMP en-keyword=mangrove kn-keyword=mangrove en-keyword=genome kn-keyword=genome en-keyword=anti-MRSA kn-keyword=anti-MRSA END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=20 article-no= start-page=3393 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20261012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cross-Cultural Adaptation and Initial Psychometric Evaluation of the Japanese Version of the Chronic Kidney Disease Self-Efficacy Scale (CKDSE-J) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Self-efficacy is an important determinant of self-care among adults with chronic kidney disease (CKD). The Chronic Kidney Disease Self-Efficacy Scale (CKD-SE) is a disease-specific measure, but its use has not been reported in Japan. This study translated and culturally adapted the CKD-SE into Japanese and conducted an initial psychometric evaluation. Methods: A cross-sectional survey was conducted among Japanese adults with CKD stages G3a?G5 not receiving dialysis. Structural validity and internal consistency were evaluated in 227 participants, and construct validity was evaluated in 222. Structural validity was examined using confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM). Results: The original 25-item four-factor CFA showed a poor fit, and ESEM yielded an improper solution involving Item 19. Sequential evaluation resulted in a 23-item structure. The 23-item CFA showed mixed fit, whereas Target ESEM showed improved overall fit (CFI = 0.935, TLI = 0.902, RMSEA = 0.060, SRMR = 0.033). However, several autonomy items showed weak target loadings and cross-loadings. Proposed subscale scores correlated positively with self-care behavior (r = 0.27?0.46), and McDonaldfs omega ranged from 0.84 to 0.90. Conclusions: The 23-item CKDSE-J showed improved overall model fit under Target ESEM, but the structural definition of autonomy remained uncertain. Because the structure was refined and evaluated in the same sample, independent replication and further psychometric evaluation are needed. en-copyright= kn-copyright= en-aut-name=GengTingting en-aut-sei=Geng en-aut-mei=Tingting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KajiwaraYuki en-aut-sei=Kajiwara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Doctorfs Program, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=self-efficacy kn-keyword=self-efficacy en-keyword=self-care kn-keyword=self-care en-keyword=cultural adaptation kn-keyword=cultural adaptation en-keyword=psychometric evaluation kn-keyword=psychometric evaluation en-keyword=exploratory structural equation modeling kn-keyword=exploratory structural equation modeling END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=7 article-no= start-page=07SP13 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Study of preload mechanism for small piezoelectric transducers with hollow structure for cryogenic environments en-subtitle= kn-subtitle= en-abstract= kn-abstract=In various industrial fields, cryogenic fluids such as liquid hydrogen and liquid nitrogen are increasingly used as fuels and refrigerants. To control the flow rate of those fluids, valves that can be operated in cryogenic environments are needed. In general, the miniaturization of the valve can be achieved by using a piezoelectric ceramic as an actuator to drive the mechanism. Additionally, the properties degradation can be suppressed by applying a preload to the piezoelectric ceramic. To miniaturize the piezoelectric actuator applying preload at low temperature conditions, we use differences in thermal expansion coefficients to apply preload to the piezoelectric ceramics. In this study, we have designed and fabricated a small piezoelectric transducer with a hollow structure for cryogenic environments by using this proposed structure. To evaluate the fabricated transducer, we have measured vibration velocity and estimated the acceleration in cryogenic environments. en-copyright= kn-copyright= en-aut-name=MimuraSouta en-aut-sei=Mimura en-aut-mei=Souta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaTakefumi en-aut-sei=Kanda en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaguchiDaisuke en-aut-sei=Yamaguchi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuboKazuki en-aut-sei=Kubo en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WakimotoShuichi en-aut-sei=Wakimoto en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20261007 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Temporally structured plasticity in death-feigning behavior in response to nutritional conditions in Tribolium castaneum en-subtitle= kn-subtitle= en-abstract= kn-abstract=Investment in antipredator behavior and foraging both directly influence fitness, yet these investments are often subject to trade-offs. In income-breeding species, individuals may initially prioritize foraging after adult emergence and subsequently increase investment in antipredator behavior as their nutritional condition improves. In this study, we investigated temporal changes in death-feigning behavior, an antipredator response, in the red flour beetle Tribolium castaneum from immediately after adult emergence. Both fed and starved individuals exhibited an increase in death-feigning duration with time after emergence. However, in starved individuals, this trend reversed after approximately 15 days, with a marked decline in duration. These results suggest that the increase in investment in death-feigning behavior early in adulthood is relatively inflexible, whereas behavioral responses become highly plastic in response to environmental conditions around day 15. Furthermore, individuals that were fed until day 18 before starvation showed a less pronounced behavioral change than those subjected to starvation from the beginning of the experimental period, suggesting that the timing of environmental exposure may influence subsequent behavioral responses. Together, these findings suggest that behavioral plasticity is not constant over time but is instead structured across developmental stages. We propose a novel conceptual framework, termed temporally structured plasticity (TSP), to describe this pattern. en-copyright= kn-copyright= en-aut-name=ShibuyaKohjiro en-aut-sei=Shibuya en-aut-mei=Kohjiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of General Systems Studies, Graduate School of Arts and Sciences, The University of Tokyo kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Avoiding attack kn-keyword=Avoiding attack en-keyword=Beetle kn-keyword=Beetle en-keyword=Playing dead kn-keyword=Playing dead en-keyword=Thanatosis kn-keyword=Thanatosis en-keyword=Post-contact immobility kn-keyword=Post-contact immobility en-keyword=Tonic immobility kn-keyword=Tonic immobility END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=2213 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20261002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Single-Cell Genomics Uncovers an Unexpectedly Abundant, Phylogenetically Hyperdiverse Patescibacteria (Candidate Phyla Radiation) Community in Agricultural Paddy Soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patescibacteria, also known as the Candidate Phyla Radiation (CPR), are among the most diverse yet functionally reduced bacterial lineages whose diversity in agricultural soils remains poorly characterized. We applied single-cell genomics to bulk soil from an unfertilized paddy field after rice harvest and drainage. From 384 randomly sorted single cells, 126 medium-to-high-quality SAGs (Single-Amplified Genomes) were recovered, spanning 24 bacterial and archaeal phyla. Unexpectedly, 108 of the 384 SAGs (28.1%) were assigned to Patescibacteria?the most frequently recovered phylum?including 42 of the 126 reliable SAGs. These genomes were notably small (mean 973 kb vs. 1.4?3.2 Mb for other phyla). Because CheckM underestimates completeness in reduced CPR genomes, CheckM2 was applied, raising mean completeness from 59.9% to 83.3% and reclassifying 15 genomes as near-complete (>90%). Phylogenomic analysis using 16 ribosomal protein markers revealed extensive diversity and low average amino acid identity to reference genomes (mean 44.6%), indicating substantial taxonomic novelty. Despite this diversity, functional annotation and OrthoFinder analysis showed a conserved, reduced gene repertoire dominated by translation and DNA repair genes and depleted in amino acid, cofactor, and nucleotide biosynthesis. These results show that modest soil sampling can recover outsized Patescibacteria diversity, underscoring the need for CPR-appropriate completeness assessment. en-copyright= kn-copyright= en-aut-name=AliArslan en-aut-sei=Ali en-aut-mei=Arslan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 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=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Patescibacteria kn-keyword=Patescibacteria en-keyword=Candidate Phyla Radiation (CPR) kn-keyword=Candidate Phyla Radiation (CPR) en-keyword=single-cell genomics kn-keyword=single-cell genomics en-keyword=paddy soil kn-keyword=paddy soil END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=11689307 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=Tourism Demand Forecasting Using Machine Learning with Cross-Model Feature Ranking en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study proposes a machine learning (ML) framework for forecasting tourist visits to a destination, leveraging feature ranking consistency across heterogeneous models. The proposed framework uses a unified stepwise feature selection pipeline to systematically determine a subset of given features that reduces prediction error of an ML model. The transferability of feature rankings is demonstrated through experiments using ML models including Random Forest, XGBoost, LightGBM, and Support Vector Regression (SVR), and a dataset related to tourist visits to West Sumatra, Indonesia. Experimental results show that i) SVR using top four features in the feature ranking based on SHAP achieves the highest accuracy and ii) application of the feature ranking based on XGBoost improves performance stability across other models, reducing error fluctuations. These findings reveal that an optimized feature subset combined with cross-model ranking transfer can outperform more complex ensembles, highlighting the importance of ranking robustness in tourism forecasting. The proposed framework provides a methodological foundation for building interpretable and dataefficient decision support systems for tourism management and policy planning. en-copyright= kn-copyright= en-aut-name=HendraYomei en-aut-sei=Hendra en-aut-mei=Yomei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MigitaTsuyoshi en-aut-sei=Migita en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiNorikazu en-aut-sei=Takahashi en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= en-keyword=tourism forecasting kn-keyword=tourism forecasting en-keyword=machine learning kn-keyword=machine learning en-keyword=support vector regression kn-keyword=support vector regression en-keyword=XGBoost kn-keyword=XGBoost en-keyword=feature ranking kn-keyword=feature ranking END start-ver=1.4 cd-journal=joma no-vol=526 cd-vols= no-issue= article-no= start-page=150819 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flavor encapsulation capacities of amphiphilic polyvinylpyrrolidone as a carrier for amorphous solid dispersions en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates the characteristics of amorphous solid dispersions (ASDs) formed using an amphiphilic carrier polymer, focusing on the effects of source solution conditions on flavor retention. Cinnamaldehyde and polyvinylpyrrolidone (PVP) were dissolved as flavor and carrier components in methanol or ethanol under different conditions and subsequently spray-dried into fine powders. The amount of cinnamaldehyde retained in the spray-dried ASDs was quantified to assess the impact of solution conditions. The results indicate that cinnamaldehyde molecules were physically entrapped within the entangled PVP chains during the spray-drying process. The flavor encapsulation capacity of PVP reached a maximum of approximately 4 mmol/g-PVP under specific conditions. This maximum capacity implies that each cinnamaldehyde molecule is associated with approximately two PVP monomer units, which is higher than those reported for selected cyclodextrin-based systems in comparable contexts of cinnamaldehyde encapsulation. Additionally, the dissipation of cinnamaldehyde from the ASD samples during storage under vacuum was examined. en-copyright= kn-copyright= en-aut-name=SatoHaruna en-aut-sei=Sato en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaNao en-aut-sei=Honda en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaTakato en-aut-sei=Hasegawa en-aut-mei=Takato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AragaChika en-aut-sei=Araga en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ImanakaHiroyuki en-aut-sei=Imanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshidaNaoyuki en-aut-sei=Ishida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ImamuraKoreyoshi en-aut-sei=Imamura en-aut-mei=Koreyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Chemical Engineering and Material Sciences, Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=7 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Flavor encapsulation kn-keyword=Flavor encapsulation en-keyword=Polyvinylpyrrolidone kn-keyword=Polyvinylpyrrolidone en-keyword=Spray-drying kn-keyword=Spray-drying en-keyword=Encapsulation capacity kn-keyword=Encapsulation capacity en-keyword=Overlap concentration kn-keyword=Overlap concentration en-keyword=Encapsulation pocket kn-keyword=Encapsulation pocket END start-ver=1.4 cd-journal=joma no-vol=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 ULK1Œs 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=

Study of Platinum Re-administration in Non-small Cell Lung Cancer Following Chemoimmunotherapy Resistance en-subtitle= kn-subtitle= en-abstract= kn-abstract=Platinum compounds represent standard treatments for various cancers. However, the efficacy of re-administrating platinum compounds has been demonstrated only in ovarian cancer and small cell lung cancer (SCLC), with its utility in non-small cell lung cancer (NSCLC) remaining unclear. Given that the prognosis of NSCLC has improved with effective treatments such as immune checkpoint inhibitors (ICIs), we propose a multicenter, single-arm, prospective phase II trial of re-administrating platinum-based combination therapy for NSCLC. Patients with NSCLC who have progressed after chemoimmunotherapy and exhibit a platinum-free interval of 85 days or more will receive carboplatin combination therapy. The drugs combined with carboplatin - pemetrexed, nab-paclitaxel, or gemcitabine - must not have been administered previously. The primary endpoint is progression-free survival (PFS), assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Assuming a threshold PFS of 4.2 months and an expected hazard ratio of 0.60, the required sample size is calculated as 40 patients to achieve 70% power with a 5% alpha error. Secondary endpoints included objective response rate, toxicity, and overall survival. This study will clarify the efficacy of re-administrating platinum compounds to patients with NSCLC who have developed resistance to chemoimmunotherapy. en-copyright= kn-copyright= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HosokawaShinobu en-aut-sei=Hosokawa en-aut-mei=Shinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokoyamaToshihide en-aut-sei=Yokoyama en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueMasaaki en-aut-sei=Inoue en-aut-mei=Masaaki 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= en-aut-name=KudoKenichiro en-aut-sei=Kudo en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaToshiaki en-aut-sei=Okada en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaedaTadashi en-aut-sei=Maeda en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawaiHaruyuki en-aut-sei=Kawai en-aut-mei=Haruyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YasugiMasayuki en-aut-sei=Yasugi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=InoueKoji en-aut-sei=Inoue en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KuyamaShoichi en-aut-sei=Kuyama en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NinomiyaTakashi en-aut-sei=Ninomiya en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OzeIsao en-aut-sei=Oze en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 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=16 ORCID= affil-num=1 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Respiratory Medicine, Kurashiki Central Hospital kn-affil= affil-num=4 en-affil=Chest Surgery, Shimonoseki City Hospital kn-affil= affil-num=5 en-affil=Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= affil-num=6 en-affil=Respiratory Medicine, National Hospital Organization Okayama Medical Center kn-affil= affil-num=7 en-affil=Respiratory Medicine, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Respiratory Medicine, National Hospital Organization Yamaguchi Ube Medical Center kn-affil= affil-num=9 en-affil=Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=10 en-affil=Respiratory Medicine, Chugoku Central Hospital kn-affil= affil-num=11 en-affil=Respiratory Medicine, Ehime Prefectural Central Hospital kn-affil= affil-num=12 en-affil=Respiratory Medicine, Iwakuni Medical Center kn-affil= affil-num=13 en-affil=Respiratory Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=14 en-affil=Division of Molecular Medicine, Aichi Cancer Center Research Institute kn-affil= affil-num=15 en-affil=Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=16 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=carboplatin kn-keyword=carboplatin en-keyword=clinical trial kn-keyword=clinical trial en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=platinum-free interval kn-keyword=platinum-free interval en-keyword=re-administration kn-keyword=re-administration 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 lysinefs 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 207 patients with R/M HNSCC treated with nivolumab or pembrolizumab at a single institution. Early progression was defined as disease progression within 90 days after ICI initiation. Associations between clinicopathological factors and early progression were evaluated using logistic regression analyses.
Results: Early progression was observed in 80 patients (38.6%). In an exploratory survival comparison, patients with early progression had significantly shorter overall survival than those without early progression. Early progression rates increased from distant-only disease to locoregional-only disease and combined locoregional and distant disease. In multivariable analysis, combined locoregional, and distant disease showed the strongest independent association with early progression. Elevated neutrophil-to-lymphocyte ratio and hypoalbuminemia were also independently associated with early progression. In contrast, treatment regimen, treatment line, number of lesions, and bulky disease were not significantly associated with early progression.
Conclusion: Disease distribution was associated with early progression after ICI initiation in patients with R/M HNSCC, with combined locoregional and distant disease showing the strongest independent association. These findings suggest that both disease status and host condition may influence failure to achieve adequate disease control shortly after ICI initiation. en-copyright= kn-copyright= en-aut-name=NodaHiroki en-aut-sei=Noda en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma 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=FujimotoShohei en-aut-sei=Fujimoto en-aut-mei=Shohei 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 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= en-keyword=head and neck squamous cell carcinoma kn-keyword=head and neck squamous cell carcinoma en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=early progression kn-keyword=early progression en-keyword=locoregional disease kn-keyword=locoregional disease en-keyword=recurrent/metastatic disease kn-keyword=recurrent/metastatic disease END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=2 article-no= start-page=143 end-page=151 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cranial and spinal computed tomography (CT) angiography with photon-counting detector CT: comparison with angiographic and operative findings en-subtitle= kn-subtitle= en-abstract= kn-abstract=The clinical imaging features of photon-counting detector (PCD) computed tomography (CT) are mainly known as dose reduction, improvement of spatial resolution, and reduction of artifacts compared to energy-integrating detector CT (EID-CT). The utility of cranial and spinal PCD-CT and PCD-CT angiography (CTA) has been previously reported. CTA is a widely used technique for noninvasive evaluation. Cranial CTA is important in brain tumors, especially glioblastoma; it evaluates whether the tumor is highly vascularized prior to an operation and helps in the diagnosis and assessment of bleeding risk. Spinal CTA has an important role in the estimation of feeders and drainers prior to selective angiography in the cases of spinal epidural arteriovenous fistulas and spinal tumors, especially in hemangioblastoma. So far, EID-CTA is commonly performed in an adjunctive role prior to selective angiography; PCD-CTA with high spatial resolution can be an alternative to selective angiography. In the cases of cerebral aneurysms, flow diverters are important tools for the treatment of intracranial aneurysms, and postoperative evaluation with cone beam CT with angiography using diluted contrast media is performed to evaluate stent adhesion and in-stent thrombosis. If CTA can replace selective angiography, it will be less invasive for the patient. In this review, we present representative cases with PCD-CT. We also show how well the cranial and spinal PCD-CTA approaches the accuracy of angiographic and intraoperative findings. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Radiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Photon-counting detector CT kn-keyword=Photon-counting detector CT en-keyword=Energy-integrating detector CT kn-keyword=Energy-integrating detector CT en-keyword=CT angiography kn-keyword=CT angiography en-keyword=Neuroimaging kn-keyword=Neuroimaging en-keyword=Spine kn-keyword=Spine 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 gthe Japan COVID-19 and Society Internet Survey,h 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=NakazatoKenfichiro en-aut-sei=Nakazato en-aut-mei=Kenfichiro 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=7 cd-vols= no-issue=1 article-no= start-page=5 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association Between Alcohol Use Patterns and Insomnia Symptoms or Poor Sleep Quality Among Adult Women: An 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 Womenfs 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 Womenfs 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=102 cd-vols= no-issue=3 article-no= start-page=438 end-page=450 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Curve Fitting Method for Analyzing Starch Granule Size Distributions in Cereals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objectives: The size distribution of starch granules is an important factor in determining the functional and nutritional properties of starch. However, a simple, standardized method for their analysis is lacking. Here, we developed an approach for estimating granule size parameters using a Python script that fits curves to volumetric granule size distributions generated using a Coulter counter.
Findings: The bimodal size distribution of starch from most wheat and barley cultivars could be best described with a mixed distribution curve. A log-normal distribution was fitted to the small B-type granules, and a normal distribution was fitted to the large A-type granules, allowing estimation of their relative abundance and size parameters despite their overlapping size distributions. However, the optimal fitting is altered in wheat mutants with large perturbations in B-type granule content. In maize and rice, which have unimodal granule size distributions, size parameters were calculated by fitting a single normal distribution.
Conclusions: Curve fitting is an effective approach for estimating starch granule size parameters in diverse cereals, particularly the Triticeae with A- and B-type granules.
Significance and Novelty: We provide new tools and guidelines for the quantitative analysis of granule size in cereals. en-copyright= kn-copyright= en-aut-name=McNellyRose en-aut-sei=McNelly en-aut-mei=Rose kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BriffaAmy en-aut-sei=Briffa en-aut-mei=Amy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YiasoumiGeorgia en-aut-sei=Yiasoumi en-aut-mei=Georgia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UauyCristobal en-aut-sei=Uauy en-aut-mei=Cristobal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= affil-num=1 en-affil=John Innes Centre kn-affil= affil-num=2 en-affil=John Innes Centre kn-affil= affil-num=3 en-affil=John Innes Centre kn-affil= affil-num=4 en-affil=John Innes Centre kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=John Innes Centre kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=3 article-no= start-page=276 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Influence of Educational Films on Antiviral Prescription for COVID-19: Insights from Web-Based Survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Prescribing antiviral agents for severe acute respiratory syndrome coronavirus 2 requires careful consideration based on the patientfs risk factors for severe disease progression and their vaccination status. However, effective interventions ensuring the appropriate use of antiviral agents by physicians have yet to be fully established. Thus, this study evaluated the impact of an educational film on antiviral prescription rates for coronavirus disease 2019 (COVID-19). Methods: This prospective, nationwide, web-based survey enrolled 1500 physicians. They were instructed to view a short educational film and assess the necessity of prescribing antiviral agents in 16 fictitious scenarios featuring adult patients with COVID-19 with varying risk factors for severe disease and vaccination statuses. We compared the antiviral prescription rates before and after viewing the educational film. Results: There was a significant increase in the antiviral prescription rates after viewing the educational film, particularly nirmatrelvir/ritonavir prescribed in cases involving immunocompromised patients (from 31.3% to 49.4%) and those with obesity (from 15.1% to 33.7%) who were unvaccinated and had no risk of drug interactions. However, viewing the educational film made little to no impact on the prescription rates for the patients with hypertension and hyperlipidemia or those with no underlying conditions. Conclusions: Short educational films may promote the appropriate use of antiviral agents for COVID-19. However, their impact on altering prescription behavior appears limited and varies according to the clinical context. en-copyright= kn-copyright= en-aut-name=KomiyaKosaku en-aut-sei=Komiya

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

Symmetrization in Hydrous Aluminous Silica Enhances Deep-Mantle Water Cycle en-subtitle= kn-subtitle= en-abstract= kn-abstract=(Al, H)-bearing CaCl2-type SiO2 serves as a key water carrier in Earth's deep-water cycle. Evolution of hydrogen-bond symmetrization in this phase was measured up to 62 GPa and 800 K by synchrotron infrared and Raman spectroscopy, and X-ray diffraction. It undergoes symmetrization at ?30 GPa and 300 K, while elevated temperature to 800 K lowers the onset pressure to ?12 GPa. This implies that the symmetrized phase will form directly near the base of the transition zone in (Al, H)-rich subducted slabs, and deeper in (Al, H)-poor slabs via transformation from stishovite. More importantly, this symmetrization state stiffens the crystal lattice and immobilizes hydrogen within the structure, enhancing water retention and preventing hydrogen loss during subduction to the lower mantle. Our findings suggest that this phase acts as an important deep-water reservoir capable of transporting water to the lower mantle, thereby linking the deep-water cycle from Earth's surface to core-mantle boundary. en-copyright= kn-copyright= en-aut-name=ZhaoChaoshuai en-aut-sei=Zhao en-aut-mei=Chaoshuai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaoZhu en-aut-sei=Mao en-aut-mei=Zhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuYingxin en-aut-sei=Yu en-aut-mei=Yingxin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SunNingyu en-aut-sei=Sun en-aut-mei=Ningyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FuYunhua en-aut-sei=Fu en-aut-mei=Yunhua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangJianbo en-aut-sei=Zhang en-aut-mei=Jianbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiermannHanns]Peter en-aut-sei=Liermann en-aut-mei=Hanns]Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=2 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=3 en-affil=Department of Earth Sciences, University of Oxford kn-affil= affil-num=4 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=5 en-affil=SKLab]DeepMinE, MOEKLab]OBCE, School of Earth and Space Sciences, Peking University kn-affil= affil-num=6 en-affil=Center for High]Pressure Science and Technology Advance Research kn-affil= affil-num=7 en-affil=Deutsches Elektronen]Synchrotron DESY kn-affil= affil-num=8 en-affil=Center for High]Pressure Science and Technology Advance Research kn-affil= affil-num=9 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=hydrogen-bond symmetrization kn-keyword=hydrogen-bond symmetrization en-keyword=(Al,H)-bearing CaCl2-type SiO2 kn-keyword=(Al,H)-bearing CaCl2-type SiO2 en-keyword=deep-water cycle kn-keyword=deep-water cycle en-keyword=high temperature and high pressure kn-keyword=high temperature and high pressure END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=002139 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260313 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of carbapenem-hydrolysing Klebsiella oxytoca strains lacking detectable carbapenemase genes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction. Carbapenemase-producing Enterobacterales (CPE) pose a clinical concern due to limited treatment options and plasmid-mediated spread of carbapenemase genes. The modified carbapenem inactivation method (mCIM) is increasingly used in clinical settings to detect CPE.
Gap Statement. Interpretation of mCIM results for isolates with reduced carbapenem susceptibility remains challenging.
Aim. To assess the interpretation of positive mCIM results in Klebsiella oxytoca isolates lacking detectable carbapenemase genes and exhibiting reduced carbapenem susceptibility and to propose a phenotypic testing strategy for accurate evaluation.
Methodology. Antimicrobial susceptibility testing with clavulanic or dipicolinic acid supplementation, phenotypic carbapenemase assays, carbapenem hydrolysis assays and whole-genome sequencing (WGS) were conducted on K. oxytoca strains.
Results. K. oxytoca strains were isolated from both blood and urine samples of a patient in a Japanese hospital. Although classified as susceptible by clinical breakpoints, these isolates exhibited reduced susceptibility to carbapenems. Although these strains were mCIM-positive, the zinc-supplemented carbapenem inactivation method did not support the presence of metallo-ƒÀ-lactamase (MBL) activity. MIC reductions in the presence of CVA were consistent with inhibition of a class A ƒÀ-lactamase. In contrast, dipicolinic acid supplementation did not reduce the meropenem MIC, ruling out MBL production. Furthermore, WGS revealed that both K. oxytoca strains lacked known carbapenemase genes, with blaOXY-2-4 being the only identifiable ƒÀ-lactamase gene encoding a class A enzyme. No novel ƒÀ-lactamase genes were identified; however, an enhanced blaOXY-2-4 expression-associated point mutation was found in the promoter region. Both K. oxytoca strains exhibited carbapenem-hydrolysing activity, although to a lesser extent than that of the MBL-producing strain.
Conclusion. We identified K. oxytoca strains that lacked known carbapenemase genes but that yielded positive mCIM results, possibly due to OXY-2 overproduction. Our study findings emphasize the need for cautious mCIM result interpretation for K. oxytoca and highlight the diagnostic value of combined susceptibility testing with clavulanic and dipicolinic acids to distinguish the underlying resistance mechanisms. Combining complementary clinical laboratory tests will enable clarification of the factors underlying mCIM positivity and guide clinical decision-making. en-copyright= kn-copyright= en-aut-name=TeraguchiHiroshi en-aut-sei=Teraguchi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OdaAyaka en-aut-sei=Oda en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakaiSatoyo en-aut-sei=Wakai en-aut-mei=Satoyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawakamiSayoko en-aut-sei=Kawakami en-aut-mei=Sayoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaKoki en-aut-sei=Yoshida en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HayashiWataru en-aut-sei=Hayashi en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitamuraNorikazu en-aut-sei=Kitamura en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugawaraYo en-aut-sei=Sugawara en-aut-mei=Yo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=SugaiMotoyuki en-aut-sei=Sugai en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YaharaKoji en-aut-sei=Yahara en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirabayashiAki en-aut-sei=Hirabayashi en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Clinical Laboratory, Kindai University Nara Hospital kn-affil= affil-num=2 en-affil=Dental School, Okayama University kn-affil= affil-num=3 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=4 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=5 en-affil=Department of Clinical Laboratory, Kindai University Nara Hospital kn-affil= affil-num=6 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=7 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=8 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=9 en-affil=Dental School, Okayama University kn-affil= affil-num=10 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=11 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= affil-num=12 en-affil=Antimicrobial Resistance Research Center, National Institute of Infectious Diseases, Japan Institute for Health Security kn-affil= en-keyword=blaOXY-2 kn-keyword=blaOXY-2 en-keyword=clavulanic acid kn-keyword=clavulanic acid en-keyword=Klebsiella oxytoca kn-keyword=Klebsiella oxytoca en-keyword=MIC kn-keyword=MIC en-keyword=modified carbapenem inactivation method kn-keyword=modified carbapenem inactivation method END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=pcag119 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260928 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Disrupted FLOWERING LOCUS C alleles from weedy radish enhance the florigenic potential of rootstocks for graft-mediated floral induction in Brassicaceae en-subtitle= kn-subtitle= en-abstract= kn-abstract=Graft-mediated floral induction is a classical yet promising breeding technique that accelerates seed production and shortens generation time in crops. However, its application remains limited to a few species because floral induction is often unstable. Even among florally induced rootstocks, grafted scions can differ in their flowering response depending on rootstock genotype, but the genetic basis of this variation remains unclear. Here, using a Brassicaceae grafting model, we investigated two early-bolting radish (Raphanus sativus) accessions differing in their ability to induce flowering. We focused on a significant difference in FLOWERING LOCUS T (FT) expression between these accessions and identified two quantitative trait loci (QTLs) associated with FT levels. Transcriptomic and genomic analyses revealed that both QTLs harbored previously unreported disrupted alleles of FLOWERING LOCUS C (FLC) homologs, key floral repressors involved in vernalization, which showed reduced expression and produced defective transcripts. Grafting experiments demonstrated that these disrupted FLC alleles enhanced floral induction, with RsFLC1 having a major effect. Our results indicate that the FT expression threshold required for graft-mediated floral induction is higher than that for rootstock flowering itself and that this threshold is reached when FLC-mediated repression is substantially reduced. These alleles were inferred to have originated from weedy radish (Raphanus raphanistrum), likely contributing to early flowering in disturbed environments. This study suggests that exploring genetic variations in FT expression is an effective strategy to develop highly florigenic rootstocks, thereby broadening the application of graft-mediated floral induction in crop breeding. en-copyright= kn-copyright= en-aut-name=MotokiKo en-aut-sei=Motoki en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSaki en-aut-sei=Kobayashi en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraKazusa en-aut-sei=Nishimura en-aut-mei=Kazusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinoshitaYu en-aut-sei=Kinoshita en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashimaMakoto en-aut-sei=Kashima en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HosokawaMunetaka en-aut-sei=Hosokawa en-aut-mei=Munetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Faculty of Science, Department of Biomolecular Science, Toho University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Faculty of Agriculture, Kindai University kn-affil= en-keyword=Brassica oleracea kn-keyword=Brassica oleracea en-keyword=FLOWERING LOCUS C kn-keyword=FLOWERING LOCUS C en-keyword=FLOWERING LOCUS T kn-keyword=FLOWERING LOCUS T en-keyword=graft-mediated floral induction kn-keyword=graft-mediated floral induction en-keyword=vernalization kn-keyword=vernalization en-keyword=weedy radish (Raphanus raphanistrum) kn-keyword=weedy radish (Raphanus raphanistrum) 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=137 cd-vols= no-issue=9 article-no= start-page=096003 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=Strain-Tuned Nodal Superconductivity in the Charge-Ordered Kagome Metal CsV3?Sb5 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The nature of the superconducting pairing symmetry in the kagome metal CsV3?Sb5 and its relationship with the charge density wave (CDW) order are central unresolved issues. Here, we investigate the evolution of superconductivity in CsV3?Sb5 under in situ uniaxial pressure using 121Sb nuclear quadrupole resonance (NQR). We find that tensile strain significantly enhances the superconducting transition temperature, ?c, while the CDW remains unchanged, demonstrating that superconductivity can be tuned independently of the bulk charge order. At a tensile strain of ? =+0.90%, the nuclear spin-lattice relaxation rate reveals a remarkable double transition: an upper transition at ?c?1=3.6??K to a nodal gap state, and a lower one at ?c?2=3.0??K characterized by a nodeless gap. These results evidence degenerate superconducting states with different gap symmetry in the kagome metal at ambient pressure which split under strain. Our Letter demonstrates a high tunability of superconductivity by uniaxial pressure. en-copyright= kn-copyright= en-aut-name=TakeuchiYusuke en-aut-sei=Takeuchi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiAkito en-aut-sei=Kobayashi en-aut-mei=Akito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UchidaSaki en-aut-sei=Uchida en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaoTakumi en-aut-sei=Nagao en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaSeigo en-aut-sei=Ogawa en-aut-mei=Seigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhouRui en-aut-sei=Zhou en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawasakiShinji en-aut-sei=Kawasaki en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SongFei en-aut-sei=Song en-aut-mei=Fei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NiHao en-aut-sei=Ni en-aut-mei=Hao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ZhaoYong en-aut-sei=Zhao en-aut-mei=Yong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZhengGuo-qing en-aut-sei=Zheng en-aut-mei=Guo-qing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= affil-num=5 en-affil=Department of Physics, Okayama University kn-affil= affil-num=6 en-affil=Institute of Physics, Chinese Academy of Sciences, and Beijing National Laboratory for Condensed Matter Physics kn-affil= affil-num=7 en-affil=Department of Physics, Okayama University kn-affil= affil-num=8 en-affil=Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering, College of Physics and Energy, Fujian Normal University kn-affil= affil-num=9 en-affil=Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering, College of Physics and Energy, Fujian Normal University kn-affil= affil-num=10 en-affil=Fujian Provincial Collaborative Innovation Center for Advanced High-Field Superconducting Materials and Engineering, College of Physics and Energy, Fujian Normal University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e77909 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SPRED2 Negatively Regulates CD8+ T Cell-Mediated Antitumor Immunity in Breast Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Activation of the RAS/RAF/ERK pathway is crucial for adaptive immunity. Here, we provide evidence that Sprouty-related EVH1 domain containing 2 (SPRED2), an endogenous inhibitor of this pathway, negatively regulates CD8+ T cell-mediated antitumor immunity in breast cancer. In EO771 and 4T1 mouse models, Spred2?/? mice exhibit reduced tumor growth, with lower endpoint lung metastatic burden in the 4T1 model, accompanied by increased T-cell infiltration and activation. Spred2?/? T cells show enhanced cytokine expression, proliferation,survival, in vitro cytotoxicity, and memory-like phenotypes, particularly among CD8+ T cells. Adoptive transfer of Spred2?/? CD8+ T cells into tumor-bearing wild-type hosts similarly reduces endpoint lung metastatic burden. MEK inhibition with U0126 attenuates increased interferon-gamma and granzyme B expression in Spred2?/? CD8+ T cells. Transcriptomic analyses reveal an inverse correlation between SPRED2 expression and antitumor CD8+ T cell states in both humans and mice. In tumor-infiltrating T cells from patients with breast cancer, SPRED2low T cells show enriched effector and cytotoxicity programs and are associated with gimmune-hoth tumors, whereas survival associations vary with CD8+ T cell context. Collectively, these findings suggest that SPRED2 functions as a cell-intrinsic negative regulator of CD8+ T-cell activation and highlight its potential as a therapeutic target to enhance T cell?based cancer immunotherapy. en-copyright= kn-copyright= en-aut-name=TianMiao en-aut-sei=Tian en-aut-mei=Miao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhaoKun en-aut-sei=Zhao en-aut-mei=Kun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Advanced International and Information Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=CD8+ T cells kn-keyword=CD8+ T cells en-keyword=immunotherapy kn-keyword=immunotherapy en-keyword=MAPK/ERK kn-keyword=MAPK/ERK en-keyword=tumor microenvironment kn-keyword=tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=4 article-no= start-page=592 end-page=605 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exploring the Clinical Diversity of Castleman Disease and TAFRO Syndrome: A Japanese Multicenter Study on Lymph Node Distribution Patterns en-subtitle= kn-subtitle= en-abstract= kn-abstract=Individuals diagnosed with Castleman disease (CD) and TAFRO syndrome (characterized by thrombocytopenia, anasarca, fever, bone marrow fibrosis, and organomegaly) displays a wide range of clinical symptoms, including varying patterns of lymph node enlargement, systemic inflammation, and impaired organ function. Some patients may present with both CD and TAFRO syndrome concurrently. A retrospective study conducted across multiple centers in Japan examined 321 cases to determine if the quantity and position of swollen lymph nodes could forecast the clinical progression and intensity of these conditions. Interestingly, the study revealed that patients with TAFRO syndrome exhibited lymphadenopathy across all ranges of lymph node region counts. Moreover, no specific clinical patterns were associated with the number of affected lymph node regions in CD patients, regardless of whether they also had TAFRO syndrome. These results enhance our understanding of the clinical variability in CD and TAFRO syndrome, suggesting that a comprehensive clinical evaluation, rather than relying solely on lymph node count, is crucial for effectively managing these conditions. Additional studies are required to establish reliable diagnostic markers and to predict disease severity at the time of diagnosis, ultimately improving patient outcomes. en-copyright= kn-copyright=

Asthma Management (PGAM): Digest edition en-subtitle= kn-subtitle= en-abstract= kn-abstract=The international and national guidelines for asthma management are typically comprehensive and designed for respiratory specialists, making them less practical for primary care physicians who handle most asthma cases. Recognizing the need for more accessible guidelines, the Japan Asthma Society developed the Practical Guidelines for Asthma Management (PGAM). PGAM aims to provide a concise summary of key asthma management principles, increasing awareness, education, and support among nonspecialists and patients alike. It includes user-friendly tables and lists outlining common symptoms, triggers, diagnostic criteria, and basic management strategies, along with frequently encountered treatable traits and comorbidities. These elements are presented through simple, clinically relevant algorithms. A notable feature of PGAM is the gBasic Roadmap for Asthma Management,h which outlines a clear sequence for patient assessment, diagnosis, and treatment from initial consultation onward, offering an easy-to-follow visual guide. Additionally, the guidelines include methods for assessing airway inflammation, enabling patient phenotyping and endotyping. This supports a personalized treatment approach, particularly with biologics, aimed at achieving clinical remission. en-copyright= kn-copyright= en-aut-name=TamaokiJun en-aut-sei=Tamaoki en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaseHiroyuki en-aut-sei=Nagase en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SanoHiroyuki en-aut-sei=Sano en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanekoTakeshi en-aut-sei=Kaneko en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GonYasuhiro en-aut-sei=Gon en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SagaraHironori en-aut-sei=Sagara en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaAkihiko en-aut-sei=Tanaka en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HoriguchiTakahiko en-aut-sei=Horiguchi en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TagayaEtsuko en-aut-sei=Tagaya en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkabaTomohiro en-aut-sei=Akaba en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TohdaYuji en-aut-sei=Tohda en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, Tokyo Women's Medical University kn-affil= affil-num=2 en-affil=Division of Respiratory Medicine and Allergology, Department of Medicine, Teikyo University School of Medicine kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine and Allergology, Kindai University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Pulmonology, Yokohama City University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Division of Respiratory Medicine, Department of Internal Medicine, Nihon University School of Medicine kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Medicine, Division of Allergology and Respiratory Medicine, School of Medicine, Showa University kn-affil= affil-num=8 en-affil=Department of Medicine, Division of Allergology and Respiratory Medicine, School of Medicine, Showa University kn-affil= affil-num=9 en-affil=Department of Respiratory Medicine, Toyota Regional Medical Center kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Tokyo Women's Medical University kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Tokyo Women's Medical University kn-affil= affil-num=12 en-affil=Kindai University Hospital kn-affil= en-keyword=Asthma kn-keyword=Asthma en-keyword=Clinical remission kn-keyword=Clinical remission en-keyword=Management guidelines kn-keyword=Management guidelines en-keyword=Treatment algorithm kn-keyword=Treatment algorithm en-keyword=Practical tool kn-keyword=Practical tool END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=2 article-no= start-page=323 end-page=337 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=Unraveling Causality: Innovations in Epidemiologic Methods en-subtitle= kn-subtitle= en-abstract= kn-abstract=For several decades, the counterfactual model and the sufficient cause model have shaped our understanding of causation in biomedical science and, more recently, the link between these two models has enabled us to obtain a deeper understanding of causality. In this article, I provide a brief overview of these fundamental causal models using a simple example. The counterfactual model focuses on one particular cause or intervention and gives an account of the various effects of that cause. By contrast, the sufficient cause model considers sets of actions, events, or states of nature which together inevitably bring about the outcome under consideration. In other words, the counterfactual framework addresses the question gwhat if?h while the sufficient cause framework addresses the question gwhy does it happen?h Although these two models are distinct and address different causal questions, they are closely related and used to elucidate the same cause-effect relationships. Importantly, the sufficient cause model makes clear that causation is a multifactorial phenomenon, and it is a gfinerh model than the counterfactual model; an individual is of one and only one response type in the counterfactual framework, whereas an individual may be at risk of none, one, or several sufficient causes. Understanding the link between the two causal models can provide greater insight into causality and can facilitate the use of each model in appropriate contexts, highlighting their respective strengths. I will briefly present three topics of interest from our research: the relationship between the concepts of confounding and of covariate balance; distinctions between attributable fractions and etiologic fractions; and the identification of operating mediation and mechanism. It is important to scrutinize observed associations in a complementary manner, using both the counterfactual model and the sufficient cause model, employing both inductive and deductive reasoning. This holistic approach will better help us to unravel causality. en-copyright= kn-copyright= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=attributable fraction kn-keyword=attributable fraction en-keyword=causal inference kn-keyword=causal inference en-keyword=confounding kn-keyword=confounding en-keyword=counterfactual model kn-keyword=counterfactual model en-keyword=covariate balance kn-keyword=covariate balance en-keyword=etiologic fraction kn-keyword=etiologic fraction en-keyword=mediation kn-keyword=mediation en-keyword=sufficient cause model kn-keyword=sufficient cause model END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=5 article-no= start-page=573 end-page=583 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tob negatively regulates NF-ƒÈB activation in breast cancer through its association with the TNF receptor complex en-subtitle= kn-subtitle= en-abstract= kn-abstract=NF-ƒÈB mediates transcriptional regulation crucial to many biological functions, and elevated NF-ƒÈB activity leads to autoimmune and inflammatory diseases, as well as cancer. Since highly aggressive breast cancers have few therapeutic molecular targets, clarification of key molecular mechanisms of NF-ƒÈB signaling would facilitate the development of more effective therapy. In this report, we show that Tob, a member of the Tob/BTG family of antiproliferative proteins, acts as a negative regulator of the NF-ƒÈB signal in breast cancer. Studies with 35 human breast cancer cell lines reveal that Tob expression is negatively correlated with NF-ƒÈB activity. Analysis of The Cancer Genome Atlas (TCGA) database of clinical samples reveals an inverse correlation between Tob expression and NF-ƒÈB activity. Tob knockdown in human breast cancer cells promoted overactivation of NF-ƒÈB upon TNF-ƒ¿ treatment, whereas overexpression of Tob inhibited TNF-ƒ¿ stimulation-dependent NF-ƒÈB activation. Mechanistically, Tob associates with the TNF receptor complex I and consequently inhibits RIPK1 polyubiquitylation, leading to possible prevention of overwhelming activation of NF-ƒÈB. en-copyright= kn-copyright= en-aut-name=TokumasuMiho en-aut-sei=Tokumasu en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoAtsuko en-aut-sei=Sato en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Ito-KurehaTaku en-aut-sei=Ito-Kureha en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoMizuki en-aut-sei=Yamamoto en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhmineNao en-aut-sei=Ohmine en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SembaKentaro en-aut-sei=Semba en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoueJun-ichiro en-aut-sei=Inoue en-aut-mei=Jun-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Immunology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Cell Signal Unit, Okinawa Institute of Science and Technology Graduate University kn-affil= affil-num=3 en-affil=Cell Signal Unit, Okinawa Institute of Science and Technology Graduate University kn-affil= affil-num=4 en-affil=Research Center for Asian Infectious Diseases, The Institute of Medical Science, The University of Tokyo kn-affil= affil-num=5 en-affil=Cell Signal Unit, Okinawa Institute of Science and Technology Graduate University kn-affil= affil-num=6 en-affil=Department of Life Science and Medical Bioscience, Waseda University kn-affil= affil-num=7 en-affil=The University of Tokyo Pandemic Preparedness, Infection and Advanced Research Center (UTOPIA) kn-affil= affil-num=8 en-affil=Cell Signal Unit, Okinawa Institute of Science and Technology Graduate University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=9 article-no= start-page=218 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First-Order Wall-Slip-Induced Departure from Inverse-Cubic Scaling of Levitation-Pressure RMS in a Push?Pull Levitation Stage en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study clarifies how rarefaction-induced wall slip in a thin gas film affects the established inverse-cubic scaling law for the spatial nonuniformity of levitation pressure in a push?pull levitation stage. The levitation force in this stage is generated by the combined action of blowing and suction. The continuum-based stress description is retained, and only the wall boundary condition is changed from the no-slip condition to a first-order slip condition. Three-dimensional incompressible unsteady Stokes simulations in a thin-gap unit-cell model are combined with a lubrication-theory scaling analysis. The effects of levitation height, blowing-velocity distribution, port-radius ratio, and computational-domain width are examined systematically. The results show that wall slip has only a minor influence at relatively large levitation heights. As the levitation height decreases, however, rarefaction-induced slip increases the flow-rate conductance. Consequently, the intensity of the spatial variation in levitation pressure is systematically reduced below that predicted by the no-slip inverse-cubic scaling law. This departure is well described by a correction relation derived from the lubrication approximation and remains robust against changes in the prescribed blowing-velocity distribution and geometric conditions. These findings provide an incompressible baseline for predicting levitation-pressure nonuniformity within the nominal gap-based Knudsen-number range examined here. en-copyright= kn-copyright= en-aut-name=UmesakiEisuke en-aut-sei=Umesaki en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroki en-aut-sei=Suzuki en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoJunji en-aut-sei=Sakamoto en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=push?pull levitation kn-keyword=push?pull levitation en-keyword=wall slip kn-keyword=wall slip en-keyword=rarefaction kn-keyword=rarefaction en-keyword=lubrication approximation kn-keyword=lubrication approximation en-keyword=pressure RMS kn-keyword=pressure RMS en-keyword=thin gas film kn-keyword=thin gas film en-keyword=Knudsen number kn-keyword=Knudsen number END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=14 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260923 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Direct evidence for water-filled yet hydraulically isolated xylem vessels in two temperate tree species en-subtitle= kn-subtitle= en-abstract= kn-abstract=Xylem vessels in sapwood are typically interpreted as either conductive or non-functional following embolism or occlusion, implicitly assuming that the presence of water within the lumen reflects participation in the transpiration stream. 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.

This study aimed to investigate the prevalence, characteristics, and outcomes of suicide-related OHCA.
Methods: This multicenter, retrospective cohort study is an analysis of data collected from the JAPAN Registry of Self-harm and Suicide Attempts. Patients were divided into two groups, the OHCA group and the non-OHCA group. The primary outcome was death at 30 days.
Results: Among 1,960 self-harm and suicide attempts patients, 213 patients (10.9 %) were assigned to the OHCA group and 1,747 (89.1%) were in the non-OHCA group. Patients in the OHCA group were older (44 vs. 33 years old, p < 0.001), and the OHCA group had a higher proportion of males compared to the non-OHCA group (122 [57.3%] vs. 604 [34.6%], p < 0.001). Despite missing and unknown data, lower proportions of psychiatric consultation history (54 [30.8%] vs. 1177 [70.5%], p < 0.001), psychiatric hospitalization history (9 [5.1%] vs. 386 [23.1%], p < 0.001), and previous suicide attempts (16 [9.2%] vs. 807 [48.4%], p < 0.001) were observed in the OHCA group. Risk of death at 30 days was significantly higher in the OHCA group (200 [93.9%] vs. 31 [1.8%], p < 0.001).
Conclusion: Suicide-related OHCA was rare and associated with poorer prognosis compared to patients without OHCA. It was more common in middle-aged men without a history of psychiatric care or prior suicide attempts, although the study was limited by missing data. en-copyright= kn-copyright= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JinnoShunta en-aut-sei=Jinno en-aut-mei=Shunta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamuraYuka en-aut-sei=Yamamura en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=2 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=3 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=4 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Epidemiology kn-affil= affil-num=5 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=6 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=7 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=8 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=9 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Epidemiology kn-affil= affil-num=10 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= en-keyword=Suicide kn-keyword=Suicide en-keyword=Cardiac arrest kn-keyword=Cardiac arrest en-keyword=Self-harm kn-keyword=Self-harm en-keyword=Out-of-hospital cardiac arrest kn-keyword=Out-of-hospital cardiac arrest END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=6 article-no= start-page=e117719 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=Association between venous access-site closure device use and postoperative nausea and vomiting after atrial fibrillation ablation under propofol sedation: a single-centre retrospective observational study in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives To examine whether the use of a venous access-site closure device is associated with the occurrence of postoperative nausea and vomiting (PONV) after atrial fibrillation (AF) ablation under propofol sedation.
Design Observational study.
Setting A single-centre retrospective observational study in Okayama, Japan.
Participants We retrospectively analysed consecutive patients who underwent AF ablation under deep propofol sedation with adaptive servo-ventilation. A total of 686 patients were included. Patients were managed using a standardised sedation protocol with or without low-dose pentazocine. Patients treated with conventional manual compression for haemostasis (n=383) were compared with those treated using a venous access-site closure device (n=303).
Interventions Postprocedural bed rest duration and the incidence and timing of PONV were compared between groups. Associations between closure device use and PONV were evaluated using logistic regression analysis.
Primary outcome measure The primary outcome was the occurrence of PONV following AF ablation.
Results All procedures were completed under propofol sedation without conversion to general anaesthesia. The duration of postprocedural bed rest was shorter in the device group than in the conventional-compression group (mean difference ?14.7 hours, 95% CI ?15.2 to ?14.0).
PONV occurred in 6/303 patients (2.0%) in the device group and 20/383 patients (5.2%) in the conventional-compression group, corresponding to a relative risk of 0.38 (95% CI 0.15 to 0.93), an OR 0.25 (95% CI 0.10 to 0.62) and a risk difference of ?3.2% (95% CI ?6.0% to ?0.5%).
In multivariable analysis, use of a venous closure device was associated with a lower likelihood of PONV.
Conclusions In this single-centre observational study, use of a venous access-site closure device was associated with a lower occurrence of PONV after AF ablation under propofol sedation. These findings suggest that postprocedural management strategies enabling earlier mobilisation may be associated with improved patient comfort; however, causal inference is limited by the observational design. en-copyright= kn-copyright= en-aut-name=SakanoueHaruna en-aut-sei=Sakanoue en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiHirosuke en-aut-sei=Yamaji en-aut-mei=Hirosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoSayaka en-aut-sei=Okamoto en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkanoKumi en-aut-sei=Okano en-aut-mei=Kumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujitaYuka en-aut-sei=Fujita en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigashiyaShunichi en-aut-sei=Higashiya en-aut-mei=Shunichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MurakamiTakashia en-aut-sei=Murakami en-aut-mei=Takashia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KusachiShozo en-aut-sei=Kusachi en-aut-mei=Shozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Nursing, Okayama Heart Clinic kn-affil= affil-num=2 en-affil=Heart Rhythm Centre, Okayama Heart Clinic kn-affil= affil-num=3 en-affil=Department of Nursing, Okayama Heart Clinic kn-affil= affil-num=4 en-affil=Department of Nursing, Okayama Heart Clinic kn-affil= affil-num=5 en-affil=Department of Nursing, Okayama Heart Clinic kn-affil= affil-num=6 en-affil=Heart Rhythm Centre, Okayama Heart Clinic kn-affil= affil-num=7 en-affil=Heart Rhythm Centre, Okayama Heart Clinic kn-affil= affil-num=8 en-affil=Graduate School of Health Sciences, Department of Medical Technology, Okayama University kn-affil= affil-num=9 en-affil=Heart Rhythm Centre, Okayama Heart Clinic kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=8 article-no= start-page=e106715 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=Study protocol for a phase II clinical trial evaluating the safety and efficacy of favipiravir injection combined with oseltamivir in influenza treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Older adults are at an increased risk of influenza-related hospitalisation and mortality due to a combination of risk factors. 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).
Ethics and dissemination Written informed consent will be obtained from all participants. This study was approved by the Center Hospital of the National Center for Global Health and Medicine Institutional Review Board (approval number: NCGM-I-022-24a) and registered in the Japan Registry of Clinical Trials.

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Hemodialysis-associated pruritus is common and can substantially impair quality of life. Given its heterogeneous pathophysiology and variable treatment response, individualized therapeutic strategies are needed. This study investigated the prevalence and severity of pruritus and clinical outcomes after switching from nalfurafine to difelikefalin. Methods: Clinical data from 108 maintenance hemodialysis patients whose pruritus severity was assessed using the Numerical Rating Scale (NRS) were retrospectively reviewed. Ten patients with persistent moderate-to-severe pruritus (NRS ? 3) despite treatment with nalfurafine were switched to difelikefalin in routine clinical practice, of whom eight completed the 16-week follow-up and were included in the switch group. Eight patients matched for age, sex, dialysis vintage, and baseline NRS served as controls. Changes in NRS scores at weeks 4 and 16, as well as adverse events, were evaluated. Results: Among 108 patients, 21 (20%) had no pruritus, while 20 (18.5%), 47 (43.5%), and 20 (18.5%) had mild, moderate, and severe pruritus, respectively. Of 14 patients receiving nalfurafine, 13 (92.9%) had persistent moderate-to-severe pruritus. In the switch group, mean NRS decreased from 5.9 } 1.7 at baseline to 2.3 } 2.3 at week 4 and 2.0 } 0.9 at week 16 (p = 0.0156 and p = 0.0078, respectively), with no meaningful change in controls. No serious adverse events strongly related to difelikefalin were identified. Conclusions: Pruritus was highly prevalent in this cohort. Switching to difelikefalin was associated with rapid and sustained improvement in patients inadequately responsive to nalfurafine, with favorable tolerability, supporting its potential role as an individualized treatment option. en-copyright= kn-copyright= en-aut-name=SakurabuYoshimasa en-aut-sei=Sakurabu en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TokunagaKumiko en-aut-sei=Tokunaga en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgisoYuko en-aut-sei=Ogiso en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MotoieMiwako en-aut-sei=Motoie en-aut-mei=Miwako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshitakeMegumi en-aut-sei=Yoshitake en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugimotoTaro en-aut-sei=Sugimoto en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Sugimoto Clinic kn-affil= affil-num=4 en-affil=Sugimoto Clinic kn-affil= affil-num=5 en-affil=Sugimoto Clinic kn-affil= affil-num=6 en-affil=Sugimoto Clinic kn-affil= affil-num=7 en-affil=Sugimoto Clinic kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=hemodialysis-associated pruritus kn-keyword=hemodialysis-associated pruritus en-keyword=difelikefalin kn-keyword=difelikefalin en-keyword=kappa-opioid receptor agonist kn-keyword=kappa-opioid receptor agonist en-keyword=refractory pruritus kn-keyword=refractory pruritus en-keyword=nalfurafine kn-keyword=nalfurafine 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=20260918 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Macroscopic and microscopic visualization of Pseudomonas syringae pv. tabaci infection using complementary bioluminescent and fluorescent reporter systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=The development of bioluminescent and fluorescent reporter systems has enabled visualization of plant-pathogenic bacterial infection dynamics, providing insights into detailed mechanisms of infection and potential applications for disease control. Pseudomonas syringae pv. tabaci 6605 (Pta) possesses quorum sensing systems and produces fluorescent pigments, which make it difficult to directly apply commonly used reporter systems. In this study, we first constructed a homologous recombination-based genomic insertion system for stable chromosomal integration of reporter genes in Pta. Using this system, we established a LuxCDABE bioluminescent system driven by the nptII promoter, which successfully enabled macroscale tracking of bacterial populations during infection. We then attempted to construct an sGFP fluorescent reporter using the same nptII promoter. However, the endogenous autofluorescence of Pta masked the sGFP signal, making quantitative detection difficult. To overcome this autofluorescence problem, we screened constitutively highly expression promoters based on transcriptome data and identified two effective promoters suitable for fluorescent monitoring of Pta infection. Together with the LuxCDABE system, this integrated platform provides comprehensive spatiotemporal analysis of virulence mechanisms and plant defense responses in the Pta pathosystem, with potential applicability to other plant-pathogenic bacteria. en-copyright= kn-copyright= en-aut-name=KuroeKana en-aut-sei=Kuroe en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=IshigaYasuhiro en-aut-sei=Ishiga en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori 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=Faculty of Life and Environmental Sciences, University of Tsukuba 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=Pseudomonas syringae pv. tabaci kn-keyword=Pseudomonas syringae pv. tabaci en-keyword=LuxCDABE kn-keyword=LuxCDABE en-keyword=sGFP-reporter kn-keyword=sGFP-reporter 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=18 cd-vols= no-issue=6 article-no= start-page=e110118 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Routine Generative AI Use and Acceptance of Medical AI: A Cross-Sectional Survey of Healthcare Workers and the Public in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Acceptance of medical artificial intelligence (AI) is critical for successful implementation, yet its acceptance may vary by clinical application and stakeholder group. Whether routine use of generative AI (GAI) is associated with acceptance of medical AI remains unclear.
Methods
A cross-sectional web survey was conducted in Japan in November 2025 using web-panel convenience sampling from an online research panel. The small analytic sample comprised 200 participants aged 20-69 years, including 100 healthcare workers and 100 non-healthcare workers. GAI use was assessed using two five-point items (GAI use at work and in daily life) and dichotomized as at least monthly use in either daily life or work versus less than monthly use in both settings, based on prespecified criteria. Acceptance of medical AI was measured for five scenario-based applications - AI-assisted imaging interpretation, AI-based health risk prediction, AI-based treatment recommendations, AI-enabled triage guidance, and AI-assisted robotic surgery - using a four-point acceptability scale; responses were dichotomized as acceptable versus not acceptable. Calibration weights were constructed to approximate Japanese internet users by raking on sex-by-age group and household income, normalized to the analytic sample size, and truncated at prespecified bounds. Adjusted prevalence ratios (aPRs) were estimated using modified Poisson regression with robust standard errors, stratified by occupation; covariates were selected a priori using a modified disjunctive cause criterion. This study was exploratory; therefore, adjustments for multiple comparisons were not performed.
Results
Among healthcare workers, the lower-use group had a higher prevalence of non-acceptance of AI-based health risk prediction (aPR 6.980, 95% CI 1.412-34.506) and AI-based treatment recommendations (aPR 4.364, 95% CI 1.331-14.305), whereas estimates for imaging interpretation, triage guidance, and robotic surgery remained statistically uncertain. Among non-healthcare workers, the lower-use group had a higher prevalence of non-acceptance of AI-assisted imaging interpretation (aPR 13.906, 95% CI 1.624-119.052), AI-based health risk prediction (aPR 4.861, 95% CI 1.133-20.862), AI-based treatment recommendations (aPR 6.288, 95% CI 1.386-28.530), and AI-assisted robotic surgery (aPR 6.173, 95% CI 1.435-26.561); the adjusted estimate for AI-enabled triage guidance was not statistically supported (aPR 1.840, 95% CI 0.521-6.505). Several estimates had wide confidence intervals, indicating substantial imprecision.
Conclusions
In this small exploratory web-panel convenience sample, lower-frequency GAI use was associated with higher non-acceptance of several medical AI applications. Associations were observed across more applications among non-healthcare workers than among healthcare workers. Because the study was cross-sectional, used convenience sampling, and included imprecise estimates with wide confidence intervals, the findings should not be interpreted causally. Larger studies using longitudinal or interventional designs are needed to clarify temporality and mechanisms. en-copyright= kn-copyright= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= en-keyword=generative ai kn-keyword=generative ai en-keyword=healthcare workers kn-keyword=healthcare workers en-keyword=medical ai kn-keyword=medical ai en-keyword=non-healthcare workers kn-keyword=non-healthcare workers en-keyword=technology acceptance kn-keyword=technology acceptance en-keyword=web-based survey kn-keyword=web-based survey END start-ver=1.4 cd-journal=joma no-vol=251 cd-vols= no-issue= article-no= start-page=114493 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2027 dt-pub=202702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A rule-based calculation approach to derive bone-suppressed chest X-ray images using photon-counting techniques en-subtitle= kn-subtitle= en-abstract= kn-abstract=Improving the visibility of lung nodules, which are often hidden by bone shadows and difficult to identify, remains a challenge in chest radiography. This study aims to develop an algorithm for generating novel bone-suppressed images using photon-counting techniques. The core idea of our algorithm is to fit photon interaction cross-sections to X-ray attenuation data measured with photon-counting detectors. Based on further calculations using the derived fitting coefficients, both density (ƒÏ) and amount-of-substance concentration (mol) were determined. The product of these values produced a ƒÏ~mol image exhibiting a clear bone-suppression effect. We conducted a virtual chest imaging simulation using 10 patient datasets acquired via clinical photon-counting computed tomography (PC-CT). The CT images were converted into ƒÏ~mol images following the proposed processing procedure, and two-dimensional chest images were generated through projection. Quantitative evaluations confirmed that the proposed images achieved sufficient bone suppression. Furthermore, commercial software provided by a vendor was used to generate bone-suppressed images from conventional images projected from CT data. A comparable bone-suppression effect on the ribs was observed between the vendor-generated images and our proposed images, while lesion visibility (e.g., lung nodules) was preserved. Additionally, bone-suppression effects in our images were observed in the vertebrae and clavicles located outside the lung fields. Our research demonstrates the value of constructing general X-ray imaging systems using photon-counting detectors. en-copyright= kn-copyright= en-aut-name=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi 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=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitaniMana en-aut-sei=Mitani en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=2 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Radiology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=5 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=6 en-affil=Division of Radiology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= en-keyword=Photon-counting detector kn-keyword=Photon-counting detector en-keyword=Bone suppression kn-keyword=Bone suppression en-keyword=Lung nodules kn-keyword=Lung nodules en-keyword=Chest radiography kn-keyword=Chest radiography en-keyword=X-ray diagnosis kn-keyword=X-ray diagnosis en-keyword=Quantitative image kn-keyword=Quantitative image END start-ver=1.4 cd-journal=joma no-vol=165 cd-vols= no-issue=10 article-no= start-page=104508 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Scaled-charge ion force field optimized for individual ion partial molar volumes in water en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present an ion partial molar volume force field for common monovalent and divalent ionic species, including Li+, Na+, K+, Cs+, Mg2+, Ca2+, F?, Cl?, Br?, I?, OH?, and H3O+. When combined with the TIP4P/2005 water model, the force field enables quantitative investigations of ion-specific effects in both bulk and interfacial properties. The iPMV force field is developed based on a single guiding principle: the ion?water interaction parameters are optimized such that the experimental partial molar volume of each individual ion at infinite dilution?determined via the ultrasonic vibrational potential method?is reproduced by construction. An exception is made for the hydronium ion, for which we also provide an alternative interface-optimized model. The force field employs a charge scaling factor of 0.75 and adopts the Lorentz?Berthelot combining rules for cross-Lennard-Jones interactions, with specific modifications for divalent cations. A distinctive feature of the iPMV force field is that, despite its straightforward design, a single set of ion parameters consistently reproduces a wide range of experimental properties?from volumetric and interfacial properties to salting-out/in effects and transport coefficients. This robust performance suggests a fundamental correlation between the partial molar volumes of individual ions and the broader physical properties of aqueous electrolyte solutions. en-copyright= kn-copyright= en-aut-name=TairaAoi en-aut-sei=Taira en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatsutoHiroyuki en-aut-sei=Katsuto en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaoKanon en-aut-sei=Nakao en-aut-mei=Kanon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Engineering, Muroran Institute of Technology kn-affil= affil-num=5 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=98 cd-vols= no-issue= article-no= start-page=107057 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=Transcriptional remodeling of local thyroid hormone metabolism is associated with feather growth termination in chicken wing feathers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Feather elongation is sustained by continuous cell proliferation within the feather follicle; however, the molecular mechanisms responsible for feather growth termination remain poorly understood. In this study, we investigated molecular changes associated with feather growth termination by comparing two chicken wing feather types with contrasting growth characteristics: primary wing feathers and primary coverts. Histological and bromodeoxyuridine incorporation analyses demonstrated that primary wing feathers remained in an active growth phase, whereas primary coverts exhibited pulp regression, reduced cell proliferation, and characteristics of growth termination. Gene expression analyses showed that primary coverts exhibited reduced expression of prolactin receptor (PRLR), type 2 iodothyronine deiodinase (DIO2), and insulin-like growth factor 2 (IGF2), together with marked induction of the thyroid hormone (TH)-inactivating enzyme type 3 iodothyronine deiodinase (DIO3). In contrast, primary wing feathers exhibited relatively higher expression of PRLR, DIO2, and IGF2 than primary coverts, while maintaining consistently low DIO3 expression. Reporter assays showed increased IGF2 promoter activity following triiodothyronine (T3) treatment in all three independent experiments, although the increase did not reach statistical significance. Thus, the reporter assay provides only tentative support for T3 responsiveness of the IGF2 promoter, consistent with our previous in vivo and primary-culture findings showing T3-dependent increases in IGF2 expression. These coordinated transcriptional changes are consistent with remodeling of local TH metabolism during the transition from active feather growth to growth termination. While local TH concentrations and direct deiodinase activities remain to be quantified, and the causal relationship between PRL/PRLR signaling and DIO3 induction remains unresolved, this study provides a molecular framework for understanding how local endocrine regulation translates systemic hormonal signals into feather type-specific growth responses during avian feather development.

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 ƒ¿-Al dendrite, Al?Si eutectic and primary Si, while their area fractions (fƒ¿-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: fƒ¿-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 fƒ¿-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 ƒ¿-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=430 cd-vols= no-issue= article-no= start-page=249 end-page=262 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=Pervasive and rapid enrichment of nitrogen in newly erupted oceanic basalt en-subtitle= kn-subtitle= en-abstract= kn-abstract=The alteration of oceanic crust by seawater is a critical sink in the global nitrogen (N) cycle, yet the mechanisms and timescales of N enrichment remain poorly constrained. We present N concentrations and isotope compositions from a 192-meter drill core (SE-02b) retrieved from the then 50-year-old Surtsey Island in Iceland, a pristine analog for rapid alteration of young oceanic basalt. The altered basaltic tuffs show significant N enrichment (average 11 } 8 ƒÊg/g), relative to unaltered Icelandic basalt glasses (0.028 } 0.026 ƒÊg/g) and MORB (?1.1 to 1.5 ƒÊg/g), matching the global average for altered oceanic crust (11 ƒÊg/g; ranging in ages from 5 to 170 Ma). Nitrogen isotope compositions (ƒÂ15Nair = ?1.7 } 4.6ñ) are primarily consistent with incorporation of seawater- and meteoric-derived ammonium (NH4+), more likely into secondary K-minerals, palagonitized glass and smectites throughout the core. To a lesser extent, N could be incorporated into Na/Ca-minerals such as analcime in the meteoric water altered zone and sulphates such as anhydrite and gypsum when present. Incorporation of NH4+ into secondary phases occurs with little isotope fractionation consistent with equilibrium fractionation between clay and aqueous NH4+. We demonstrate that seawater-rock interaction alone can produce the ubiquitous background N enrichment of the oceanic crust without the addition of remobilized N from sedimentary sources. Such magnitude of enrichment is also observed via meteoric water alteration. Localized high enrichments in N in areas of enhanced fluid flow at core SE-02b with exceptionally low ƒÂ15N values (as low as ?20.1ñ), are attributed to abiotic reduction of dissolved N2 under anoxic conditions and/or microbial activity. We propose that N incorporation into the oceanic crust can occur rapidly in days to decades rather than at a constant rate over geologic time. This has major implications for N transfer in subduction zones, N exchange between the oceanic crust, seawater and the atmosphere and for planetary habitability. en-copyright= kn-copyright= en-aut-name=Bustos-MorenoJuan Felipe en-aut-sei=Bustos-Moreno en-aut-mei=Juan Felipe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WeisenbergerTobias B. en-aut-sei=Weisenberger en-aut-mei=Tobias B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=BeboutGray E. en-aut-sei=Bebout en-aut-mei=Gray E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Earth and Environmental Sciences, Lehigh University kn-affil= affil-num=2 en-affil=Geology and Sustainable Mining Institute, University Mohammed VI Polytechnic kn-affil= affil-num=3 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=5 en-affil=Department of Earth and Environmental Sciences, Lehigh University kn-affil= en-keyword=Nitrogen isotopes kn-keyword=Nitrogen isotopes en-keyword=Nitrogen cycling kn-keyword=Nitrogen cycling en-keyword=Hydrogen isotopes, carbon isotopes, oxygen isotopes, altered oceanic crust kn-keyword=Hydrogen isotopes, carbon isotopes, oxygen isotopes, altered oceanic crust en-keyword=Hydrothermal alteration kn-keyword=Hydrothermal alteration en-keyword=Surtsey kn-keyword=Surtsey en-keyword=Iceland kn-keyword=Iceland END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=3 article-no= start-page=e70062 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=Sexual Dimorphism in Vertebral Number: Developmental Implications Inferred From Vertebral and Body Proportions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Segmentation is a fundamental feature of vertebrate body plans, and variation in vertebral number contributes substantially to morphological diversity. Although sexual dimorphism in vertebral number has been documented in several vertebrate lineages, its developmental basis remains poorly understood. Here, we report pronounced sexual dimorphism in vertebral number in the western Indian endemic ricefish Oryzias setnai, distributed across ~1800?km. Radiographic analyses of individuals collected throughout its range revealed that vertebral number increased with latitude in both sexes, while males consistently possessed more vertebrae than females irrespective of geographic origin. Size-adjusted analyses showed that this dimorphism is associated with sex differences in head size and position-dependent variation in vertebral length. However, positional allometric analyses demonstrated that both the magnitude and direction of these sex differences vary markedly during growth. In particular, among smaller individuals, posterior vertebrae were relatively shorter in males than in females, suggesting reduced somite length in the posterior body axis of male embryos and potentially reflecting sex-specific differences in the dynamics of somitogenesis. Given that this variation arises between males and females within a single species sharing an essentially identical genetic background, O. setnai provides a rare empirical system not only for linking early developmental processes to intraspecific sexual variation in vertebrate body plans but also as a powerful model to investigate the developmental basis of body plan variation across species. en-copyright= kn-copyright= en-aut-name=YamahiraKazunori en-aut-sei=Yamahira en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AnoopV.

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 studentsf application of health checkup reports: analysis using health literacy skills framework kn-title=’†E‚E‘åŠw¶‚ÌŒ’fŒ‹‰ÊŠˆ—p‚Ì‘£i—vˆö?ƒwƒ‹ƒXƒŠƒeƒ‰ƒV[ƒXƒLƒ‹ƒtƒŒ[ƒ€ƒ[ƒN‚ð—p‚¢‚½ŒŸ“¢? 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 gApplication of Health Checkup Reports,h gHealth Interest,h gHealth Literacy (HL),h gReadability of The Health Checkup Report,h gReading Comprehension of The Report,h and gDecision-making Balance.h 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 gReadabilityh to gReading comprehension,h gReading comprehensionh to gDecision-making,h gDecision-makingh to gApplication,h gHealth Interesth to gReading comprehension,h gDecision-making,h and gApplication,h gHLh to gApplicationh were significant across all school types. Conversely, the paths from gHealth Interesth and gReadabilityh to gHL,h and gHLh to gReading comprehensionh and gDecision-making,h 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=–Ú“IFŠwZŒ’Nf’fŒ‹‰ÊŠˆ—piˆÈ‰ºCŠˆ—pj‚ÆŠÖ˜A—vˆö‹y‚Ñ‘ŠŒÝ‚ÌŠÖ˜A«‚ðƒwƒ‹ƒXƒŠƒeƒ‰ƒV[ƒXƒLƒ‹ƒtƒŒ[ƒ€ƒ[ƒN‚ð—p‚¢‚Ä–¾‚ç‚©‚É‚·‚邱‚Æ‚ð–Ú“I‚Æ‚µ‚½D

However, the clinical significance of immune checkpoint inhibitor (ICI) timing and treatment sequencing remains unclear. This study investigated their association with clinical outcomes after NIR-PIT.
Methods This multicenter retrospective study included 44 patients with 48 lesions who underwent initial NIR-PIT between January 2021 and March 2026. The primary analysis compared outcomes according to prior ICI exposure. An exploratory analysis evaluated outcomes according to treatment sequence and timing of ICI administration. The primary endpoint was local control. Secondary endpoints were objective response rate and disease control rate, while overall survival was assessed exploratorily.
Results Median local control duration was 253 days, but was 174 days in the prior ICI exposure group and 342 days in the non-prior ICI exposure group (log-rank P = 0.031). Local progression occurred in 69.2?37.1% of lesions, respectively (P = 0.059). Among 45 evaluable lesions, the objective response rate and disease control rate were 60.0?93.3%, respectively. Median overall survival was 866 days. Exploratory analyses suggested potential differences in clinical outcomes according to treatment sequence and ICI timing.
Conclusions Prior ICI exposure was associated with poorer local control after NIR-PIT. Exploratory analyses suggested that ICI timing and treatment sequencing may influence clinical outcomes. Treatment sequencing may represent an important consideration when integrating NIR-PIT and ICIs for recurrent or metastatic head and neck cancer. 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=FujimotoShohei en-aut-sei=Fujimoto en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=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= affil-num=1 en-affil=Department of Otolaryngology - Head and Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Otolaryngology - Head and Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=4 en-affil=Department of Otolaryngology Head and Neck Surgery, Japanese Red Cross Society Himeji Hospital 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= en-keyword=Near-infrared photoimmunotherapy kn-keyword=Near-infrared photoimmunotherapy en-keyword=Immune checkpoint inhibitor kn-keyword=Immune checkpoint inhibitor en-keyword=Head and neck cancer kn-keyword=Head and neck cancer en-keyword=Treatment sequence kn-keyword=Treatment sequence en-keyword=Local control kn-keyword=Local control END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Seizures associated with clozapine augmentation by other antipsychotics: a pharmacovigilance?pharmacodynamic analysis using VigiBase en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Clozapine is associated with a high risk of central nervous system abnormalities. However, seizure risk related to interactions between clozapine and other antipsychotics remains poorly characterized, and the pharmacological mechanisms underlying these seizures are unclear. Objectives: We aimed to evaluate safety signals for seizures associated with clozapine augmentation by other antipsychotics and analyze the relationship between these signals and neurotransmitter receptor occupancy profiles.
Design: A pharmacovigilance?pharmacodynamic analysis using a spontaneous reporting system.
Methods: This pharmacovigilance study used VigiBase, an adverse drug reaction database maintained by the World Health Organization. Drug?drug interactions (DDIs) between clozapine and other antipsychotics were assessed using the ƒ¶ shrinkage measure model. The association between DDI signals and neurotransmitter receptor occupancy was evaluated using linear regression. Robustness was tested using four frequency statistical models: additive, multiplicative, combination risk ratio, and chi-square statistic models. Results: Of 38,758,077 reports in VigiBase between 1990 and 2024, 230,371 involved clozapine. Among antipsychotics classified under ATC code N05A, DDIs with clozapine were detected for amisulpride, chlorpromazine, haloperidol, lurasidone, olanzapine, penfluridol, risperidone, sulpiride, zotepine, and zuclopenthixol. A significant association between dopamine D4 receptor occupancy and the point estimates of signal values was observed in the ƒ¶ shrinkage measure model (ƒÀ?=?0.295, 95% confidence interval: 0.119?0.471, p?=?0.002) and replicated across all frequency statistical models.
Conclusions: These findings suggest a potential role of dopamine D4 receptor occupancy in seizures associated with clozapine augmentation by other antipsychotics. Further large-scale epidemiological studies are needed to validate these findings. en-copyright= kn-copyright= en-aut-name=HatanoMasakazu en-aut-sei=Hatano en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KandaMasaya en-aut-sei=Kanda en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KosekiTakenao en-aut-sei=Koseki en-aut-mei=Takenao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaiTsuyoshi en-aut-sei=Nakai en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriiRina en-aut-sei=Horii en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshiharaNozomi en-aut-sei=Yoshihara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitoTakeo en-aut-sei=Saito en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakechiKenshi en-aut-sei=Takechi en-aut-mei=Kenshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EsumiSatoru en-aut-sei=Esumi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamadaShigeki en-aut-sei=Yamada en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Pharmacotherapeutics and Informatics, Fujita Health University School of Medicine kn-affil= affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Asahikawa Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacotherapeutics and Informatics, Fujita Health University School of Medicine kn-affil= affil-num=5 en-affil=Department of Pharmacotherapeutics and Informatics, Fujita Health University School of Medicine kn-affil= affil-num=6 en-affil=Department of Pharmacotherapeutics and Informatics, Fujita Health University School of Medicine kn-affil= affil-num=7 en-affil=Department of Pharmacotherapeutics and Informatics, Fujita Health University School of Medicine kn-affil= affil-num=8 en-affil=Department of Psychiatry, Fujita Health University School of Medicine kn-affil= affil-num=9 en-affil=Department of Drug Information Analysis, College of Pharmaceutical Sciences, Matsuyama University kn-affil= affil-num=10 en-affil=The Faculty of Pharmaceutical Sciences, Kobe Gakuin University kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Pharmacotherapeutics and Informatics, Fujita Health University School of Medicine kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stereoselective synthesis of ƒÀ,ƒÀ-diborylalanine (AlaBB) and its incorporation into oligopeptides en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the stereoselective synthesis of ƒÀ,ƒÀ-diborylalanine (AlaBB), a compact amino acid scaffold designed to introduce a gem-diboronic acid motif as a branched connector in peptides.

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 Hartmannfs reversal (HR) performed in a patient with severe perioperative allergies.
CASE PRESENTATION: A 73-year-old woman underwent an emergency open Hartmannfs 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=Hartmannfs reversal kn-keyword=Hartmannfs 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=14 cd-vols= no-issue=8 article-no= start-page=e00484-26 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260804 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-throughput screening system for antimycobacterial compounds using in vitro infected cells: construction and application to compounds in the ?mura Natural Compound Library en-subtitle= kn-subtitle= en-abstract= kn-abstract=The global increase in multidrug-resistant tuberculosis strains poses a major threat; consequently, there is an urgent need to identify and develop novel drugs. We have previously presented a simple fibroblast assay (SFA) screening method that enables the simultaneous assessment of antibacterial activity and cytotoxicity toward host cells. This method was developed based on our finding that live (but not dead) Mycobacterium tuberculosis bacilli exhibit cytotoxic activity against human lung fibroblasts, and that this cytotoxicity, which is proportional to the number of viable bacterial cells, is inhibited by known antimycobacterial drugs. While conventional methods to measure M. tuberculosis growth require 2?4 weeks to detect antibacterial activity; the SFA method enables detection within 2?3 days and can detect compounds that are active within host cells. Here, we applied high-throughput screening, based on assessment of cytotoxicity, to identify candidate antimycobacterial agents. In parallel, by comparing the direct antibacterial activity of compounds in liquid medium (using the broth dilution test) with that observed via SFA, we developed a new SFA-based screening system to select compounds with low cytotoxicity that are active outside or inside the host cells. Using this dual system, we screened 742 compounds from the ?mura Natural Compound Library (Kitasato University, Japan), with 62 hits. Of these, 19 were excluded owing to their toxicity, and six exhibited antibacterial activity only via SFA screening. Four promising antimycobacterial candidates with no cytotoxicity at the 10 ƒÊg/mL threshold?aridicin A, lankamycin, streptovaricin, and lariatin A?were identified. identified.This novel system supports the rapid identification of low-cytotoxicity antimycobacterial compounds that are active inside or outside the host cells. en-copyright= kn-copyright= en-aut-name=TakiiTakemasa en-aut-sei=Takii en-aut-mei=Takemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimishimaAoi en-aut-sei=Kimishima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwatsukiMasato en-aut-sei=Iwatsuki en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeYoshihiro en-aut-sei=Watanabe en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=AsamiYukihiro en-aut-sei=Asami en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Mycobacterium Reference and Research, The Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=2 en-affil=?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=3 en-affil=?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=4 en-affil=?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=5 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Density and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=?mura Satoshi Memorial Institute, Kitasato University kn-affil= en-keyword=Mycobacterium tuberculosis kn-keyword=Mycobacterium tuberculosis en-keyword=Mycobacterium avium kn-keyword=Mycobacterium avium en-keyword=Mycobacterium abscessus kn-keyword=Mycobacterium abscessus en-keyword=fibroblasts kn-keyword=fibroblasts en-keyword=the ?mura Natural Compound Library kn-keyword=the ?mura Natural Compound Library en-keyword=antibacterial activity kn-keyword=antibacterial activity 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=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stereoselective synthesis of ƒÀ,ƒÀ-diborylalanine (AlaBB) and its incorporation into oligopeptides en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the stereoselective synthesis of ƒÀ,ƒÀ-diborylalanine (AlaBB), a compact amino acid scaffold designed to introduce a gem-diboronic acid motif as a branched connector in peptides.

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 ƒÊm 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=54 cd-vols= no-issue=6 article-no= start-page=upaf104 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vesicle-combined PtBi/C catalyst for base-free conversion of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid en-subtitle= kn-subtitle= en-abstract= kn-abstract=A conversion of 5-hydroxymethylfurfural to 2,5-frandicarboxylic acid (FDCA) was catalyzed by using a catalyst of PtBi-activated carbon (PtBi/C) combined with vesicles made of phospholipid. No alteration of the electron state of the PtBi/C by vesicles was observed. However, FDCA was obtained under mild-temperature and base-free conditions. The yield of FDCA depended on the hydration nature of vesicles. It was therefore suggested that vesicles gave bound water as a novel driving force for the reaction. The present finding would explore an application of vesicles to new catalytic reactions that are different from conventional biochemical reactions. en-copyright= kn-copyright= en-aut-name=ShimanouchiToshinori en-aut-sei=Shimanouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DeguchiKoji en-aut-sei=Deguchi en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuharaKazuma en-aut-sei=Yasuhara en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraYukitaka en-aut-sei=Kimura en-aut-mei=Yukitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Materials Science, Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=2,5-frandicarboxylic acid kn-keyword=2,5-frandicarboxylic acid en-keyword=metal-supported catalyst kn-keyword=metal-supported catalyst en-keyword=vesicles kn-keyword=vesicles 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 2Œ-O-Acetyl-1Œ-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 2Œ-O-acetyl-N 2-(N,N-dimethylaminomethylene)-1Œ-O-(4-methoxybenzyl)-3-[2-(4-nitrophenyl)ethyl]-l-biopterin, an appropriately protected precursor of 1Œ-O- and 2Œ-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 ƒÂ15N and ƒÂ13C; 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=53 cd-vols= no-issue=13 article-no= start-page=e2025GL120078 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Limits of Water Storage in Stishovite at Deep Mantle Conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=The deep Earth water cycle is a key process in Earth's evolution. Stishovite has been proposed as a major carrier of water from the surface into the lower mantle. However, its role remains unclear because its water solubility is controversial. We investigated the water solubility of Al-free stishovite at pressures of 33?38 GPa and temperatures of 700?1200 K using in situ X-ray diffraction in an advanced multianvil apparatus. Water solubility is high, around 3 wt%, at 700 K but decreases rapidly with increasing temperature and becomes negligible (<1,000 ppm), at temperatures above 1000 K. These results suggest that pure stishovite is unlikely to transport significant amounts of water into Earth's lower mantle under comparable pressure-temperature conditions. Previously reported high water contents in pure stishovite under deep Earth conditions likely reflect the solubility of post-stishovite or experimental artifacts. en-copyright= kn-copyright= en-aut-name=WangFei en-aut-sei=Wang en-aut-mei=Fei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChanyshevArtem en-aut-sei=Chanyshev en-aut-mei=Artem kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ManLianjie en-aut-sei=Man en-aut-mei=Lianjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SongYunke en-aut-sei=Song en-aut-mei=Yunke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangLin en-aut-sei=Wang en-aut-mei=Lin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=TsujinoNoriyoshi en-aut-sei=Tsujino en-aut-mei=Noriyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BhatShrikant en-aut-sei=Bhat en-aut-mei=Shrikant kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FarlaRobert en-aut-sei=Farla en-aut-mei=Robert kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatsuraTomoo en-aut-sei=Katsura en-aut-mei=Tomoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=Bayerisches Geoinstitut, University of Bayreuth kn-affil= affil-num=5 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= affil-num=6 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=7 en-affil=Japan Synchrotron Radiation Research Institute kn-affil= affil-num=8 en-affil=Deutsches Elektronen]Synchrotron DESY kn-affil= affil-num=9 en-affil=Deutsches Elektronen]Synchrotron DESY kn-affil= affil-num=10 en-affil=Bayerisches Geoinstitut, University of Bayreuth kn-affil= en-keyword=stishovite kn-keyword=stishovite en-keyword=high pressure kn-keyword=high pressure en-keyword=deep mantle kn-keyword=deep mantle en-keyword=multianvil press kn-keyword=multianvil press en-keyword=water cycle kn-keyword=water cycle 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 en-aut-sei=Nakano en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaReina en-aut-sei=Maeda en-aut-mei=Reina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SajiMarie en-aut-sei=Saji en-aut-mei=Marie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirataRei en-aut-sei=Hirata en-aut-mei=Rei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YukawaMotomi en-aut-sei=Yukawa en-aut-mei=Motomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkudaShizuka en-aut-sei=Okuda en-aut-mei=Shizuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiranoMiyu en-aut-sei=Hirano en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HabaraToshihiro en-aut-sei=Habara en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HayashiNobuyoshi en-aut-sei=Hayashi en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama Couplefs Clinic Womenfs Health Checkup Center kn-affil= affil-num=2 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Senior Embryologist, Okayama Couplefs Clinic kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama Couplefs Clinic Womenfs Health Checkup Center kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama Couplefs Clinic Womenfs Health Checkup Center kn-affil= affil-num=10 en-affil=Department of Medical Technology, Okayama Couplefs Clinic kn-affil= affil-num=11 en-affil=Department of Reproductive Medicine, Okayama Couplefs Clinic kn-affil= affil-num=12 en-affil=Department of Reproductive Medicine, Okayama Couplefs Clinic kn-affil= en-keyword=Breast ultrasonography kn-keyword=Breast ultrasonography en-keyword=Infertility treatment kn-keyword=Infertility treatment en-keyword=Women in their 30s kn-keyword=Women in their 30s en-keyword=Breast cancer screening kn-keyword=Breast cancer screening en-keyword=Multidisciplinary care kn-keyword=Multidisciplinary care END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=9 article-no= start-page=e70259 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Marine flatworms as windows into the evolution of bilaterian neuropeptide signalling en-subtitle= kn-subtitle= en-abstract= kn-abstract=The evolutionary origin(s) of neuropeptide signalling is still largely unknown. It has been hypothesised that signal transmission via neuropeptides played a crucial role in the regulation of nervous systems in the bilaterian ancestor. Identification, expression and functional analyses of neuropeptides and their receptors across different taxonomic groups are important for better understanding the origin(s) of bilaterian neuropeptide signalling. An example is flatworms belonging to the Platyhelminthes (spiralian protostomes) and Xenacoelomorpha (sister to all Bilateria or sister to Ambulacraria). Despite their simple morphology (i.e., a body plan lacking a coelom and circulatory system), they often possess brain-like central nervous systems and a number of bilaterian-conserved neuropeptides. This feature makes them useful models for analyses of neuropeptides and their links to nervous systems. Although previous studies have revealed orthologous relationships between vertebrate neuropeptides and those found in both marine Platyhelminthes and Xenacoelomorpha, our work suggests possible ancestral functions of vasopressin/oxytocin (VP/OT) peptides (platytocin) in these groups. en-copyright= kn-copyright= en-aut-name=NakamuraRyo en-aut-sei=Nakamura en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BaillyXavier en-aut-sei=Bailly en-aut-mei=Xavier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Multicellular Marine Models Team, CNRS ?

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=46 cd-vols= no-issue=9 article-no= start-page=5141 end-page=5154 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=Antiproteinuric Effect of SGLT2 Inhibitors in Patients With Hepatocellular Carcinoma Receiving Atezolizumab Plus Bevacizumab en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduce proteinuria in patients with diabetes mellitus and chronic kidney disease. However, their effect on vascular endothelial growth factor inhibitor-induced proteinuria remains unclear. This study evaluated the prophylactic effect of SGLT2i on bevacizumab-induced proteinuria in patients with hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab.
Patients and Methods: This multicenter retrospective study included patients with HCC who started therapy with atezolizumab plus bevacizumab between September 2020 and December 2023. The primary outcome was the time to exacerbation of proteinuria from baseline within 6 months after treatment initiation according to SGLT2i use. Secondary outcomes included the development of grade ?2 proteinuria.
Results: A total of 188 patients were included, of whom 29 received SGLT2i. No significant difference in the time to exacerbation of proteinuria was observed between the SGLT2i and non-SGLT2i groups considering the overall population (median: 157 vs. 116 days, p=0.95). Multivariate analysis identified diabetes with systolic blood pressure ?130 mmHg as an independent risk factor for proteinuria exacerbation (hazard ratio=2.19, 95% confidence interval=1.18-4.06, p=0.013), whereas SGLT2i use was not significantly associated with proteinuria exacerbation. In patients with both diabetes and systolic blood pressure ?130 mmHg, SGLT2i significantly prolonged the time to proteinuria exacerbation.
Conclusion: SGLT2i may suppress proteinuria progression only in high-risk patients with HCC complicated by diabetes and hypertension. en-copyright= kn-copyright= en-aut-name=HORITOMOKI en-aut-sei=HORI en-aut-mei=TOMOKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=AOIHIROSHI en-aut-sei=AOI en-aut-mei=HIROSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KOIZUMIYUSUKE en-aut-sei=KOIZUMI en-aut-mei=YUSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KUROMATSUMAKOTO en-aut-sei=KUROMATSU en-aut-mei=MAKOTO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FUKUIAIKO en-aut-sei=FUKUI en-aut-mei=AIKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OKAMOTOHIROYO en-aut-sei=OKAMOTO en-aut-mei=HIROYO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HIRATAATSUSHI en-aut-sei=HIRATA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SHINMORIKENTARO en-aut-sei=SHINMORI en-aut-mei=KENTARO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IMANAKAYUKI en-aut-sei=IMANAKA en-aut-mei=YUKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NAMBAMIYU en-aut-sei=NAMBA en-aut-mei=MIYU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KITAMURASYUNSUKE en-aut-sei=KITAMURA en-aut-mei=SYUNSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NAKANISHIKEISUKE en-aut-sei=NAKANISHI en-aut-mei=KEISUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TSUSHIMAHIDEO en-aut-sei=TSUSHIMA en-aut-mei=HIDEO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= en-aut-name=MORIYAKEI en-aut-sei=MORIYA en-aut-mei=KEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=MATSUIMASARU en-aut-sei=MATSUI en-aut-mei=MASARU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=IKUSHIMASHIGEKI en-aut-sei=IKUSHIMA en-aut-mei=SHIGEKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Department of Pharmacy, Nara Prefecture General Medical Center kn-affil= affil-num=2 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Pharmacy, Nara Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Nara Medical University Hospital kn-affil= affil-num=5 en-affil=Department of Pharmacy, Tenri Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Kindai University Nara Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Kindai University Nara Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Kindai University Nara Hospital kn-affil= affil-num=9 en-affil=Department of Pharmacy, Yamatotakada Municipal Hospital kn-affil= affil-num=10 en-affil=Department of Pharmacy, Yamatotakada Municipal Hospital kn-affil= affil-num=11 en-affil=Department of Pharmacy, Nara Prefecture General Medical Center kn-affil= affil-num=12 en-affil=Department of Nephrology, Nara Medical University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology, Nara Prefecture General Medical Center kn-affil= affil-num=14 en-affil=Department of Nephrology, Nara Prefecture General Medical Center kn-affil= affil-num=15 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=16 en-affil=Department of Gastroenterology, Nara Prefecture General Medical Center kn-affil= affil-num=17 en-affil=Department of Nephrology, Nara Medical University Hospital kn-affil= affil-num=18 en-affil=Department of Pharmacy, Nara Prefecture General Medical Center kn-affil= en-keyword=Hepatocellular carcinoma kn-keyword=Hepatocellular carcinoma en-keyword=bevacizumab kn-keyword=bevacizumab en-keyword=proteinuria kn-keyword=proteinuria en-keyword=sodium glucose transporter 2 inhibitors kn-keyword=sodium glucose transporter 2 inhibitors END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=100628 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=Clinical phenotypes and the risk factors of mild pulmonary hypertension en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The definition of pulmonary hypertension (PH) was revised as mean pulmonary arterial pressure (mPAP) >20?mmHg from ?25?mmHg in the recent PH guidelines; however, the characteristics of PH patients with mPAP 21?24 mmHg have not been well described.
Methods: A total of 1080 individuals who underwent right heart catheterization (2018?2022) was categorized into 3 groups by mPAP: no PH with mPAP ?20?mmHg, mild PH with mPAP 21?24 mmHg, and conventional PH with mPAP ?25?mmHg. We assessed PH subtypes of hemodynamic and clinical classification and compared survival outcomes (all-cause mortality, heart failure hospitalization, lung transplant) using Cox models.
Results: Of them, 391 patients (36.2%) were diagnosed as PH including mild PH (n = 137) and conventional PH (n = 254). Phenotypically, mild PH was predominantly characterized by pre-capillary hemodynamics and Group 2 clinical classification. Mild PH is associated with an intermediate prognosis: outcomes are more favorable than in conventional PH but inferior to no PH (HR 1.74 [95% CI 1.15?2.61]). While the two PH phenotypes appear to share comorbidity-related factors, hemodynamic parameters were associated with survival outcomes not in mild PH but in conventional PH.
Conclusions: The observation that mild PH constitutes approximately one-third of overall PH cases carries substantial clinical weight. The newly identified mild PH cohort was characterized mainly by pre-capillary and Group 2 subtypes. While mild PH is associated with an intermediate prognosis, comorbidities appear to be the primary determinant of outcomes in this group, unlike in conventional PH where hemodynamics play a larger role. en-copyright= kn-copyright= en-aut-name=TayaSatoshi en-aut-sei=Taya en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EjiriKentaro en-aut-sei=Ejiri en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukudaYoshitake en-aut-sei=Fukuda en-aut-mei=Yoshitake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanezawaMisaki en-aut-sei=Kanezawa en-aut-mei=Misaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=mild pulmonary hypertension kn-keyword=mild pulmonary hypertension en-keyword=prognosis kn-keyword=prognosis en-keyword=risk factor kn-keyword=risk factor 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= cd-vols= no-issue= article-no= start-page= 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=Incidental detection of cancers during population-based endoscopic gastric cancer screening in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Upper gastrointestinal endoscopy traverses the full upper aerodigestive tract, unlike radiography, potentially enabling incidental detection of non-gastric malignancies. However, its population-level incidental detection rate for non-gastric upper aerodigestive tract cancers has not been systematically quantified. The aim of this study was to compare endoscopic screening with radiography and quantify detection of non-gastric upper aerodigestive tract cancers in a population-based setting.
Methods This population-based cohort study was conducted by linking the Okayama City municipal gastric cancer screening registry with the Kokuho Database (KDB) for fiscal years 2016?2021. Among 36,326 participants contributing 64,822 screening examinations (40,832 radiography; 23,990 endoscopy), diagnoses of oral cavity, pharyngeal, laryngeal, and esophageal cancer occurring within 2 months of screening were ascertained from the KDB. Generalized estimating equations with modified Poisson regression were used to estimate adjusted risk ratios (aRRs) comparing endoscopy with radiography.
Results Endoscopic screening was significantly associated with higher composite incidental detection rates for non-gastric upper aerodigestive tract cancers (95.9 vs. 34.3 per 100,000 examinations; aRR 2.94, 95% confidence interval [CI] 1.50?5.76; p?=?0.002). Specifically, esophageal cancer detection was markedly higher with endoscopy (83.4 vs. 17.1 per 100,000; aRR 5.16, 95% CI 2.16?12.32; p? Conclusions Endoscopic gastric cancer screening is associated with substantially higher incidental detection of non-gastric upper aerodigestive tract cancers, particularly esophageal cancer. These findings suggest an additional detection value for endoscopy that extends beyond its primary gastric cancer target in organized screening programs. 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=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoKenji en-aut-sei=Fujimoto en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayaseShunsaku en-aut-sei=Hayase en-aut-mei=Shunsaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology?Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Otolaryngology?Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Occupational Health Data Science Center, University of Occupational and Environmental Health kn-affil= affil-num=7 en-affil=Department of Epidemiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Epidemiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Gastric cancer screening kn-keyword=Gastric cancer screening en-keyword=Endoscopy kn-keyword=Endoscopy en-keyword=Radiography kn-keyword=Radiography en-keyword=Early detection of cancer kn-keyword=Early detection of cancer en-keyword=Esophageal neoplasms kn-keyword=Esophageal neoplasms 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=32 cd-vols= no-issue=7 article-no= start-page=103553 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Patient-centred communication in radiographer education: A five-country comparative document analysis of curriculum and competency standards en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Patient-centred communication is fundamental to radiographic practice, particularly when patients experience anxiety or uncertainty during imaging or treatment. However, it remains unclear whether broad communication expectations in radiography education and professional standards are translated into explicit, observable behaviours and integrated into education and assessment. This comparative document analysis examined the representation of patient-centred communication in selected national-level documents from five countries, using listening-related behaviours as an illustrative example.
Methods: Selected national-level curriculum, accreditation, registration, capability, and competency documents from the United States, the United Kingdom, Australia, Canada, and Japan were analysed deductively using a predefined extraction framework. The framework assessed communication competence, listening-related behaviours, patient-centred care, patient/family relationships, interprofessional collaboration, education, and assessment.
Results: Communication was addressed in all five selected national-level document sets, although institutional framing differed. It was framed as a professional competency or capability in the United Kingdom and Australia, a role-based competency framework in Canada, clinical competency and accreditation requirements in the United States, and primarily as curriculum content in Japan. Explicit observable behavioural expectations, such as listening-related behaviours, were uncommon. Listening was explicitly defined only in the Australian capability standards; elsewhere, it was represented indirectly through broader concepts, such as patient interaction, information gathering, and interpersonal communication.
Conclusion: The selected documents differed in the explicitness, structure, and educational integration of communication-related standards, without implying differences in education quality or clinical outcomes. Defining patient-centred communication through observable behaviours may strengthen alignment among professional expectations, learning outcomes, feedback, and assessment.
Implications for practice: Operationalising patient-centred communication as observable behaviours may enhance curriculum mapping, feedback, and assessment in radiographer education. en-copyright= kn-copyright= en-aut-name=KomatsuY. en-aut-sei=Komatsu en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChikamotoY. en-aut-sei=Chikamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukanoK. en-aut-sei=Tsukano en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeS. en-aut-sei=Abe en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsudouS. en-aut-sei=Tsudou en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoY. en-aut-sei=Yamamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanabeY. en-aut-sei=Tanabe en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Independent Researcher kn-affil= affil-num=3 en-affil=Department of Psychosomatic Medicine, Yokohama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=Radiographer education kn-keyword=Radiographer education en-keyword=Patient-centred communication kn-keyword=Patient-centred communication en-keyword=Listening kn-keyword=Listening en-keyword=Competency standards kn-keyword=Competency standards en-keyword=Curriculum standards kn-keyword=Curriculum standards en-keyword=Document analysis kn-keyword=Document analysis END start-ver=1.4 cd-journal=joma no-vol=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=137 cd-vols= no-issue= article-no= start-page=103183 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=Activation phosphorylation and dephosphorylation dynamics of Ca2+/Calmodulin-dependent protein kinase Iƒ¿ in HeLa cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ca??/calmodulin-dependent protein kinase I (CaMKI), a multifunctional CaM-activated protein kinase, is involved in various Ca?? signaling pathways including neuronal development. Here, we characterize the phosphorylation at Thr177 (an activation Thr residue) and subsequent dephosphorylation dynamics of CaMKIƒ¿ in HeLa cells upon physiological stimulation that elevates intracellular Ca??. ATP induced CaMKIƒ¿ phosphorylation within 5?10 min; phosphorylation was then blocked by CaMKK inhibitor TIM-063, or by the depletion of extracellular Ca??. This was followed by gradual dephosphorylation to basal levels within 30?60 min. Histamine induced CaMKIƒ¿ phosphorylation, peaking within 3?4 min; this process was abolished by treatment with either TIM-063 or intracellular Ca?? chelation using BAPTA-AM and thapsigargin; however, not by extracellular Ca?? depletion. CaMKIƒ¿ was then rapidly dephosphorylated to basal levels within 10 min. Consistently, histamine-induced (but not ATP-induced) CaMKIƒ¿ phosphorylation was absent in triple IP? receptor-knockout HeLa cells. Dephosphorylation of CaMKIƒ¿ after ATP-induced phosphorylation was unaffected by okadaic acid or CaMK phosphatase (CaMKP, known as PPM1F) inhibitors (ANS and ANDS). We found that HeLa cell extracts contained Mg2+/Mn2+-dependent CaMKIƒ¿ dephosphorylation activity that was insensitive to ANS and ANDS. Furthermore, co-expression of PP2Cƒ¿ fully abolished ATP-, histamine-, or ionomycin-stimulated CaMKIƒ¿ phosphorylation, which is consistent with in vitro dephosphorylation of CaMKIƒ¿ at Thr177 by recombinant PP2Cƒ¿. Taken together, these results reveal that agonist-induced Ca?? influx from the extracellular space or release from intracellular stores transiently activates CaMKK-CaMKIƒ¿ signaling in HeLa cells, which is shut off by dephosphorylation catalyzed by PP2Cƒ¿ as a promising candidate for CaMKIƒ¿ phosphatase. en-copyright= kn-copyright= en-aut-name=ChenYerun en-aut-sei=Chen en-aut-mei=Yerun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MikiMasao en-aut-sei=Miki en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhtsukaSatomi en-aut-sei=Ohtsuka en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EtoMasumi en-aut-sei=Eto en-aut-mei=Masumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshidaAtsuhiko en-aut-sei=Ishida en-aut-mei=Atsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuizuFutoshi en-aut-sei=Suizu en-aut-mei=Futoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MizutaniAkihiro en-aut-sei=Mizutani en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AndoHideaki en-aut-sei=Ando en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MikoshibaKatsuhiko en-aut-sei=Mikoshiba en-aut-mei=Katsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TokumitsuHiroshi en-aut-sei=Tokumitsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Veterinary Science, Okayama University of Science kn-affil= affil-num=6 en-affil=Laboratory of Molecular Brain Science, Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=7 en-affil=Clinical Examination Department, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=8 en-affil=Department of Pharmacotherapeutics, Showa Pharmaceutical University kn-affil= affil-num=9 en-affil=Laboratory for Developmental Neurobiology, RIKEN Center for Brain Science kn-affil= affil-num=10 en-affil=Shanghai Institute for Advanced Immunochemical Studies, ShanghaiTech University kn-affil= affil-num=11 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=CaMKIƒ¿ kn-keyword=CaMKIƒ¿ en-keyword=CaMKK kn-keyword=CaMKK en-keyword=PP2Cƒ¿ kn-keyword=PP2Cƒ¿ en-keyword=Phosphorylation kn-keyword=Phosphorylation en-keyword=Dephosphorylation kn-keyword=Dephosphorylation en-keyword=Ca2+-signaling kn-keyword=Ca2+-signaling END start-ver=1.4 cd-journal=joma no-vol=146 cd-vols= no-issue=9 article-no= start-page=864 end-page=876 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Optimization of Smart Grid Operation Considering Diverse Electricity Consumption Patterns kn-title=‘½—l‚È“d—ÍÁ”ïŒ`‘Ô‚ðl—¶‚µ‚½ƒXƒ}[ƒgƒOƒŠƒbƒh‰^—p‚ÌÅ“K‰» en-subtitle= kn-subtitle= en-abstract= kn-abstract=@This study examines an optimal operation model for a smart grid composed of multiple microgrids to promote renewable energy use in Japan. In Japan, about 70% of electricity is still supplied by fossil fuel power, while renewables account for only 18% despite a 36?38% target for 2030. Using demand and photovoltaic data from Setagaya Ward, we construct a system model with factory/office and residential microgrids and formulate a mathematical optimization model that considers power interchange, batteries and heat storage. Numerical experiments based on several case studies show the effectiveness of smart grid operation designed according to the proposed model in promoting renewable energy utilization and reducing total generation cost. In particular, the results show that increasing photovoltaic capacity, increasing the number of microgrids, and considering heat demand are all effective measures. However, these benefits depend on the season. Future work should extend the system model to account for seasonal variability and associated investment costs. en-copyright= kn-copyright= en-aut-name=KawamotoTakaki en-aut-sei=Kawamoto en-aut-mei=Takaki kn-aut-name=ì–{‘ìŽ÷ kn-aut-sei=ì–{ kn-aut-mei=‘ìŽ÷ aut-affil-num=1 ORCID= en-aut-name=TodaYuriko en-aut-sei=Toda en-aut-mei=Yuriko kn-aut-name=ŒË“c—I从q kn-aut-sei=ŒË“c kn-aut-mei=—I从q aut-affil-num=2 ORCID= en-aut-name=HasuikeTakashi en-aut-sei=Hasuike en-aut-mei=Takashi kn-aut-name=˜@’r—² kn-aut-sei=˜@’r kn-aut-mei=—² aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ affil-num=2 en-affil=School of Creative Science and Engineering, Waseda University kn-affil=‘ˆî“c‘åŠw‘åŠw‰@‘n‘¢—HŠwŒ¤‹†‰È affil-num=3 en-affil=School of Creative Science and Engineering, Waseda University kn-affil=‘ˆî“c‘åŠw‘åŠw‰@‘n‘¢—HŠwŒ¤‹†‰È en-keyword=ƒXƒ}[ƒgƒOƒŠƒbƒh (smart grid) kn-keyword=ƒXƒ}[ƒgƒOƒŠƒbƒh (smart grid) en-keyword=ƒ}ƒCƒNƒƒOƒŠƒbƒh (microgrid) kn-keyword=ƒ}ƒCƒNƒƒOƒŠƒbƒh (microgrid) en-keyword=Ķ‰Â”\ƒGƒlƒ‹ƒM[ (renewable energy) kn-keyword=Ķ‰Â”\ƒGƒlƒ‹ƒM[ (renewable energy) en-keyword=“d—Í—Z’Ê (power interchange) kn-keyword=“d—Í—Z’Ê (power interchange) END start-ver=1.4 cd-journal=joma no-vol=192 cd-vols= no-issue= article-no= start-page=147 end-page=159 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=A Community-Based Collaborative Project Toward an Inclusive Society Through Dance: A Case Study of Inclusive Dance Practice at the Okayama Uraja Festival kn-title=ƒ_ƒ“ƒX‚ð’Ê‚¶‚½‹¤¶ŽÐ‰ï‚ÌŽÀŒ»‚ÉŒü‚¯‚½’nˆæ‹¦“­ƒvƒƒWƒFƒNƒg \ ‰ªŽR‚¤‚炶‚áÕ‚è‚É‚¨‚¯‚éƒCƒ“ƒNƒ‹[ƒVƒuƒ_ƒ“ƒXŽÀ‘H \ en-subtitle= kn-subtitle= en-abstract= kn-abstract=@Ⴊ‚¢ŽÒ‚Ì•¶‰»Œ|pŠˆ“®‚Å‚ÍCႪ‚¢ŽÒ‚ª‘n‘¢‚â”­M‚ÉŽå‘Ì“I‚ÉŠÖ‚í‚邱‚Æ‚ªdŽ‹‚³‚ê‚Ä‚¢‚éB‚µ‚©‚µC‚»‚̈êŒ`‘Ô‚Å‚ ‚éƒCƒ“ƒNƒ‹[ƒVƒuƒ_ƒ“ƒX‚ð’nˆæŽÐ‰ï‚ÉŠJ‚©‚ꂽ•¶‰»Šˆ“®‚Ö‚Æ“WŠJ‚·‚鎖—á‚Ì•ªÍ‚Í\•ª‚Å‚Í‚È‚¢B‚»‚±‚Å–{e‚Å‚ÍC‰ªŽRŒ§‚Ìu‚¤‚炶‚ávÕ‚è‚É‚¨‚¢‚Ä”­‘«‚µ‚½ƒCƒ“ƒNƒ‹[ƒVƒu—x‚è˜AuˆêŠúˆê‰ï?—Ö•‘‰·—…v‚ð‘ÎÛ‚ÉCƒCƒ“ƒNƒ‹[ƒVƒu‚¤‚炶‚áƒ_ƒ“ƒX‚ÌŠJ”­‚¨‚æ‚ÑŽÀ‘H‰ß’ö‚ð®—‚µ‚½BŠˆ“®‹L˜^C‰f‘œ‹L˜^CŠˆ“®Ž‘—¿‚ð‚à‚Æ‚É•ªÍ‚µ‚½Œ‹‰ÊC•\Œ»“à—e‚âŽÀŽ{•û–@C‰‰•‘ŠÂ‹«‚ªCŽQ‰ÁŽÒ‚ÌSg‚Ì“Á«‚𓥂܂¦‚Ä’iŠK“I‚É’²®‚³‚ê‚Ä‚¢‚½‚±‚Æ‚ª–¾‚ç‚©‚Æ‚È‚Á‚½B‚Ü‚½CŽQ‰ÁŽÒ‚ÌŽåŠÏ“I‰^“®‹­“x‚ÍŽå‚ÉuŠyv‚©‚çu‚â‚â‚«‚‚¢v‚͈̔͂ɕª•z‚µCŠˆ“®–ž‘«“x‚à‚‚¢ŒXŒü‚ðŽ¦‚µ‚½BˆÈã‚æ‚èC–{ƒvƒƒWƒFƒNƒg‚ÍC’nˆæ•¶‰»‚ðŠî”Õ‚Æ‚µ‚½ƒCƒ“ƒNƒ‹[ƒVƒu‚Èg‘Ì•\Œ»Šˆ“®‚ÉŠÖ‚·‚éŠî‘b“I’mŒ©‚ð’ñ‹Ÿ‚·‚é‚à‚Ì‚Å‚ ‚é‚Æl‚¦‚ç‚ê‚éB en-copyright= kn-copyright= en-aut-name=YOSHIMURARisako en-aut-sei=YOSHIMURA en-aut-mei=Risako kn-aut-name=‹g‘º—˜²Žq kn-aut-sei=‹g‘º kn-aut-mei=—˜²Žq aut-affil-num=1 ORCID= en-aut-name=ODAAito en-aut-sei=ODA en-aut-mei=Aito kn-aut-name=¬“cˆ¤“l kn-aut-sei=¬“c kn-aut-mei=ˆ¤“l aut-affil-num=2 ORCID= en-aut-name=CHIUWing In en-aut-sei=CHIU en-aut-mei=Wing In kn-aut-name=æâ‰o›J kn-aut-sei=æâ kn-aut-mei=‰o›J aut-affil-num=3 ORCID= en-aut-name=TANIGAWASayaka en-aut-sei=TANIGAWA en-aut-mei=Sayaka kn-aut-name=’Jì¹–ç‰Ì kn-aut-sei=’Jì kn-aut-mei=¹–ç‰Ì aut-affil-num=4 ORCID= en-aut-name=SAKOHaruko en-aut-sei=SAKO en-aut-mei=Haruko kn-aut-name=ŽðŒüŽ¡Žq kn-aut-sei=ŽðŒü kn-aut-mei=Ž¡Žq aut-affil-num=5 ORCID= affil-num=1 en-affil=The Joint Graduate School in Science of School Education, Hyogo University of Teacher Education kn-affil=•ºŒÉ‹³ˆç‘åŠw‘åŠw‰@˜A‡ŠwZ‹³ˆçŠwŒ¤‹†‰È affil-num=2 en-affil=Resorttrust, Inc. kn-affil=ƒŠƒ][ƒgƒgƒ‰ƒXƒgŠ”Ž®‰ïŽÐ affil-num=3 en-affil=The Joint Graduate School in Science of School Education, Hyogo University of Teacher Education kn-affil=•ºŒÉ‹³ˆç‘åŠw‘åŠw‰@˜A‡ŠwZ‹³ˆçŠwŒ¤‹†‰È affil-num=4 en-affil=The Joint Graduate School in Science of School Education, Hyogo University of Teacher Education kn-affil=•ºŒÉ‹³ˆç‘åŠw‘åŠw‰@˜A‡ŠwZ‹³ˆçŠwŒ¤‹†‰È affil-num=5 en-affil=Faculty of Education, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@‹³ˆçŠwˆæ en-keyword=ƒCƒ“ƒNƒ‹[ƒVƒuƒ_ƒ“ƒX kn-keyword=ƒCƒ“ƒNƒ‹[ƒVƒuƒ_ƒ“ƒX en-keyword=‚¤‚炶‚á kn-keyword=‚¤‚炶‚á en-keyword=Ⴊ‚¢ŽÒ kn-keyword=Ⴊ‚¢ŽÒ en-keyword=ƒ_ƒ“ƒX kn-keyword=ƒ_ƒ“ƒX en-keyword=g‘Ì•\Œ» kn-keyword=g‘Ì•\Œ» 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=20260708 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Streptococcal toxic shock syndrome caused by ST525 Streptococcus dysgalactiae subsp. equisimilis with genomic characterization of virulence and antimicrobial resistance en-subtitle= kn-subtitle= en-abstract= kn-abstract=Streptococcus dysgalactiae subsp. equisimilis (SDSE) is an emerging cause of severe invasive infections. We describe the clinical course of an immunocompromised patient with advanced breast cancer who developed streptococcal toxic shock syndrome, necrotizing fasciitis, and disseminated intramuscular abscesses caused by a multidrug-resistant Lancefield group G SDSE isolate, alongside a comprehensive genomic characterization of its virulence and antimicrobial resistance profiles. Genomic analysis identified the isolate as emm subtype stG840.0 and sequence type 525 (ST525), harboring genes encoding several virulence-associated factors, including an emm-like gene encoding an M-like surface protein, streptokinase, streptolysin O, streptolysin S, and SpeG. Through comprehensive genomic analysis of the highly virulent SDSE isolate, we provided insights into its underlying genetic background. Further accumulation of genomic data is expected to fully elucidate the mechanisms of virulence and antimicrobial resistance in SDSE. en-copyright= kn-copyright= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma 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=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaniokaMaki en-aut-sei=Tanioka en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health 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 Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=5 en-affil=Clinical Oncology Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= en-keyword=Streptococcus dysgalactiae subsp. equisimilis kn-keyword=Streptococcus dysgalactiae subsp. equisimilis en-keyword=Streptococcal toxic shock syndrome kn-keyword=Streptococcal toxic shock syndrome en-keyword=Necrotizing fasciitis kn-keyword=Necrotizing fasciitis en-keyword=emm typing kn-keyword=emm typing en-keyword=Multilocus sequence typing kn-keyword=Multilocus sequence typing en-keyword=Whole-genome sequencing kn-keyword=Whole-genome sequencing END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=4 article-no= start-page=2155 end-page=2156 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=Rectal syphilis: a great imitator of rectal malignancy en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 48-year-old transgender woman presented with a sudden onset of bloody stool.

The patient lacked classic signs of syphilis, such as anal pain, primary genital chancres, or localized lymphadenopathy. However, serological assays were highly reactive, and immunohistochemical analysis of the biopsy specimen confirmed the presence of Treponema pallidum, establishing the diagnosis of syphilitic proctitis. A four-week oral amoxicillin regimen (1,500 mg/day) led to complete clinical and serological resolution. This elusive condition must be considered when evaluating anorectal mucosal abnormalities. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Syphilitic proctitis kn-keyword=Syphilitic proctitis en-keyword=Lower gastrointestinal syphilis kn-keyword=Lower gastrointestinal syphilis en-keyword=Sexually transmitted infection kn-keyword=Sexually transmitted infection 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.

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=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=Ž©‘R’E—Ž‚µ‚½Žq‹{Œ´”­ DLBCL ‚ɑ΂µ‚Ä Pola-R-CHP —Ö@‚Æ CNS Ä”­—\–h‚ðs‚Á‚½‚P—á 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=’·“cW kn-aut-sei=’·“c kn-aut-mei=W aut-affil-num=1 ORCID= en-aut-name=KimuraMaiko en-aut-sei=Kimura en-aut-mei=Maiko kn-aut-name=–Ø‘º^ˆßŽq kn-aut-sei=–Ø‘º kn-aut-mei=^ˆßŽq aut-affil-num=2 ORCID= en-aut-name=MuneishiManaka en-aut-sei=Muneishi en-aut-mei=Manaka kn-aut-name=@Έ¤‰Ô kn-aut-sei=@Î kn-aut-mei=ˆ¤‰Ô aut-affil-num=3 ORCID= en-aut-name=MurayamaKozo en-aut-sei=Murayama en-aut-mei=Kozo kn-aut-name=‘ºŽRWŽO kn-aut-sei=‘ºŽR kn-aut-mei=WŽO aut-affil-num=4 ORCID= en-aut-name=NiiyaDaigo en-aut-sei=Niiya en-aut-mei=Daigo kn-aut-name=V’J‘åŒå kn-aut-sei=V’J kn-aut-mei=‘åŒå aut-affil-num=5 ORCID= en-aut-name=TakeuchiMakoto en-aut-sei=Takeuchi en-aut-mei=Makoto kn-aut-name=’|“འkn-aut-sei=’|“à kn-aut-mei=½ aut-affil-num=6 ORCID= en-aut-name=FujiiSoichiro en-aut-sei=Fujii en-aut-mei=Soichiro kn-aut-name=“¡ˆä‘ˆê˜Y kn-aut-sei=“¡ˆä kn-aut-mei=‘ˆê˜Y aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È affil-num=2 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È affil-num=3 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È affil-num=4 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È affil-num=5 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È affil-num=6 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È affil-num=7 en-affil=Department of Hematology, Japanese Red Cross Okayama Hospital kn-affil=‰ªŽRÔ\Žš•a‰@@ŒŒ‰t“à‰È en-keyword=‚Ñ‚Ü‚ñ«‘å×–EŒ^‚a×–EƒŠƒ“ƒpŽî (diffuse large B-cell lymphoma) kn-keyword=‚Ñ‚Ü‚ñ«‘å×–EŒ^‚a×–EƒŠƒ“ƒpŽî (diffuse large B-cell lymphoma) en-keyword=Žq‹{Œ´”­ƒŠƒ“ƒpŽî (primary uterine lymphoma) kn-keyword=Žq‹{Œ´”­ƒŠƒ“ƒpŽî (primary uterine lymphoma) en-keyword=Pola-R-CHP—Ö@ (Pola-R-CHP regimen) kn-keyword=Pola-R-CHP—Ö@ (Pola-R-CHP regimen) en-keyword=HD-MTX—Ö@ (HD-MTX regimen) kn-keyword=HD-MTX—Ö@ (HD-MTX regimen) 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 SARM1fs 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 SARM1fs 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=270 cd-vols= no-issue= article-no= start-page=157103 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=The effect of end-gas auto-ignition flame properties on the knocking intensity of a dual-fuel hydrogen engine en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study sought to elucidate the mechanism governing PRE-mixed mixture ignition in end-gas region (PREMIER) combustion in a dual-fuel hydrogen engine. Both knocking and PREMIER combustion are induced by end-gas auto-ignition, but differ in terms of the subsequent development of pressure waves. Knocking is accompanied by strong waves, whereas PREMIER combustion is characterized by the absence of, or very few, such waves. End-gas auto-ignition of hydrogen?air mixtures was visualized while in-cylinder pressure was measured using an optical compression and expansion machine. The visualization data indicate that KI increased as the spread velocity of the end-gas auto-ignition front rose. That velocity remained below 100?m/s during PREMIER combustion, but attained approximately 400?m/s in severe knocking cycles. The theory proposed by Bradley was used to evaluate the experimental results, and two dimensionless parameters, ƒÌ and ƒÃ, were estimated. The ƒÌ-ƒÃ diagram showed a distinct transition from PREMIER combustion to knocking.

Herein, we report a new class of photoresponsive liquid-crystalline (LC) adhesives based on organic/inorganic nanostructured colloidal hybrids. These LC materials are composed of a biomineral-inspired hydroxyapatite (HAp) nanorod and azobenzene-based forklike molecules. The organic/inorganic LC hybrids exhibit unusual photo-enhanced adhesion upon photoinduced order?disorder phase transitions of these LC materials. The photoresponsive adhesion functions of the colloidal LC hybrids are tuned by spacer moieties of the forklike molecules as well as mixing of the hybrids with the forklike molecules. The reversible photo-enhanced adhesion of the LC hybrids is achieved when the forklike molecule having oligooxyethylene spacers is hybridized with the HAp nanorod. The flexible oligooxyethylene spacers of the forklike molecule are effective for the formation of less ordered packing of the azobenzene units in the LC hybrids, which enables the dynamic photoresponsive functions. We propose an approach to the development of bioinspired photoresponsive LC materials through self-assembly of functional organic molecules and biomineral-based colloidal hybrids. en-copyright= kn-copyright= en-aut-name=UchidaJunya en-aut-sei=Uchida en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KiguchiRyuta en-aut-sei=Kiguchi en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoRiki en-aut-sei=Kato en-aut-mei=Riki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoTakashi en-aut-sei=Kato en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry and Biotechnology School of Engineering, The University of Tokyo kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=adhesion kn-keyword=adhesion en-keyword=biominerals kn-keyword=biominerals en-keyword=colloids kn-keyword=colloids en-keyword=liquidcrystals kn-keyword=liquidcrystals en-keyword=organic/inorganichybrids kn-keyword=organic/inorganichybrids en-keyword=photoresponsivematerials kn-keyword=photoresponsivematerials en-keyword=self-assembly kn-keyword=self-assembly END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=FM4B.2 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=Demonstration of a Raman Silicon Nanocavity Laser Emitting in the L-Band with S-band excitation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We demonstrated a Raman silicon nanocavity laser that enables wavelength conversion from the S-band to the L-band.

Propidium monoazide (PMA) was also used to distinguish between viable and non-viable cells. Microbiota composition differed between the laboratory and the on-site workflow. After cool transport, the abundances of Lactobacillus and Turicibacter increased, while those of Streptococcus, Bradyrhizobium, and Acinetobacter decreased. Based on the ƒÀ-diversity assessment, the difference between viable and non-viable cells was marginal compared with the difference between on-site and laboratory workflows. In the subsequent on-site workflow experiment, seasonal variation was clearly demonstrated. The relative abundances of Lactobacillus, Turicibacter, and Bacillus were high in September; Staphylococcus, Phenylobacterium, and Bradyrhizobium in November; and Phyllobacterium in January. The seasonal effect was greater than the PMA treatment effect. Despite the studyfs limitations, such as a limited number of milk samples and data from only one farm with a single management system, our findings indicate that storage and transport at low temperatures could lead to inaccurate assessments, particularly of opportunistic environmental microbiota. Viability PCR could help improve our understanding of the factors involved but would not substantially alter the raw milk microbiota. en-copyright= kn-copyright= en-aut-name=TranPhong Dinh en-aut-sei=Tran en-aut-mei=Phong Dinh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsurutaTakeshi en-aut-sei=Tsuruta en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishinoNaoki en-aut-sei=Nishino en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cow milk kn-keyword=cow milk en-keyword=cold storage kn-keyword=cold storage en-keyword=microbiota kn-keyword=microbiota en-keyword=seasonal variation kn-keyword=seasonal variation en-keyword=viability kn-keyword=viability 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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Micro-segregation of Primary Si in ADC14 (Al?17Si?4Cu) Alloy Produced by Unidirectional Continuous Casting en-subtitle= kn-subtitle= en-abstract= kn-abstract=An upgrading approach for hypereutectic Al?Si alloys was investigated through controlled segregation of Si using a unidirectional casting process. The precipitation behavior and spatial distribution of primary Si in the hypereutectic ADC14 (Al?17Si?4Cu) alloy were systematically examined at different casting speeds (0.06, 1.9, and 10 mm/s). Microstructural observations revealed that high casting speed suppresses primary Si formation due to rapid solidification, whereas intermediate speed leads to a relatively uniform distribution of primary Si. In contrast, low casting speed combined with a holding period for 2 min promotes pronounced segregation and coarsening of primary Si in localized regions. Energy-dispersive X-ray spectroscopy analysis confirmed significant fluctuations in Si concentration along the casting direction, particularly after process interruption. Based on these results, a preliminary upgrading process was proposed, involving the selective removal of Si-enriched regions followed by remelting. This approach resulted in a reduction of Si content to approximately 13.9 wt.%, corresponding to a decrease of about 3%. The results demonstrate that controlling solidification behavior to induce phase separation provides a promising and energy-efficient strategy for upgrading recycled Al?Si alloys. 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=upgrading technique kn-keyword=upgrading technique en-keyword=Al?Si alloy kn-keyword=Al?Si alloy en-keyword=primary Si kn-keyword=primary Si en-keyword=segregation kn-keyword=segregation en-keyword=unidirectional solidification kn-keyword=unidirectional solidification 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, 5Œ- and 3Œ-rapid amplification of cDNA ends (RACE) analyses were performed. While 3Œ RACE showed a shared polyadenylation site, 5Œ 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=165 cd-vols= no-issue=7 article-no= start-page=074308 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260821 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-resolution analysis of the S1?S0 transition of magnesium phthalocyanine: Rotational structure and electronic angular momentum en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a high-resolution spectroscopic analysis of the S1?S0 transition of magnesium phthalocyanine (MgPc), obtained by probing buffer-gas-cooled molecules with a narrow-linewidth laser. The observed spectrum exhibits a characteristic three-peak pattern, which is well reproduced by modeling MgPc as an oblate symmetric top with D4h symmetry. A key result of this work is that the spectrum is strongly influenced by electronic Coriolis coupling, which is associated with electronic angular momentum. The electronic Coriolis constant is determined to be ?2, indicating an effective orbital angular momentum of about 2 in the excited S1 state, originating from the ƒÎ-conjugated ring excitation. This provides a direct spectroscopic signature of electronic angular momentum in a large polyatomic molecule. The presence of nonzero electronic orbital angular momentum is qualitatively consistent with the perimeter model of phthalocyanines. The value lies within the range inferred from previous magnetic circular dichroism (MCD) studies. Compared with the previous MCD estimate, the present analysis provides a more state-specific and narrower constraint, demonstrating that high-resolution spectroscopy enables direct access to electronic and magnetic properties beyond conventional structural characterization. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaKoichi M.

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

angiosarcoma of the breast: a literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objective: Primary angiosarcoma of the breast (PBA) is an extremely rare and heterogeneous disease. PBA is difficult to diagnose and has a poor prognosis. In order to better understand the disease and provide evidence-based treatment for PBA patients, a review of the published literature in the English language was conducted.
Methods: A literature review in agreement with the PRISMA protocol was conducted. Medline and Cochrane databases were searched for English articles on PBA patients in September 2023 with a predetermined strategy. The articles were categorized and assessed based on hierarchical levels of scientific evidence.
Key Content and Findings: A total of 255 articles were identified, among these 137 publications which included 1,888 patients met the criteria for inclusion in the final analysis. No prospective, randomized trials exclusive to PBA have been recognized. This article provides an overview of the most current and comprehensive evidence concerning the epidemiology, etiology, genomic features, clinical presentations, diagnosis, treatment, and prognosis of PBA.
Conclusions: Despite the fact that current evidence is largely derived from retrospective studies, database analyses, and case reports, we utilized this information to tackle important clinical questions concerning optimal patient management practices for PBA. Complete surgical excision continues to be the mainstay treatment for PBA. However, the effectiveness of adjuvant therapies is still unclear. This narrative review highlights the urgent need for more rigorously designed research to enhance the management and treatment strategies for PBA. en-copyright= kn-copyright= en-aut-name=ZhuYidan en-aut-sei=Zhu en-aut-mei=Yidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamotoShogo en-aut-sei=Nakamoto en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataniYoko en-aut-sei=Iwatani en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwataniTsuguo en-aut-sei=Iwatani en-aut-mei=Tsuguo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhangXinfeng en-aut-sei=Zhang en-aut-mei=Xinfeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaniokaMaki en-aut-sei=Tanioka en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Breast Surgery, Liaoning Cancer Hospital & Institute kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Breast Surgery, Liaoning Cancer Hospital & Institute kn-affil= affil-num=8 en-affil=Department of Clinical AI Human Resources Development Program, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=Primary angiosarcoma of the breast (PBA) kn-keyword=Primary angiosarcoma of the breast (PBA) en-keyword=complete surgical excision kn-keyword=complete surgical excision en-keyword=hierarchal levels of scientific evidence kn-keyword=hierarchal levels of scientific evidence en-keyword=literature review kn-keyword=literature review 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-ƒ¿ 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-ƒ¿ 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-ƒ¿. Short-term exposure led to upregulation of Tgf-ƒÀ, 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-ƒÈB 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-ƒ¿ (tumor necrosis factor-alpha) kn-keyword=TNF-ƒ¿ (tumor necrosis factor-alpha) END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=7 article-no= start-page=1352 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diabetes Burden in the Middle East and North Africa Region, 1990?2023: An Ecological Time-Trend Analysis of GBD Estimates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objectives: The Middle East and North Africa (MENA) region has one of the highest age-standardized diabetes prevalence rates globally, yet all-age, diabetes-specific evidence incorporating GBD 2023 estimates through 2023 remains limited. Materials and Methods: Using Global Burden of Disease (GBD) 2023 estimates for 21 MENA countries from 1990 to 2023, this ecological time-trend analysis quantified 33-year trends in incidence, prevalence, mortality, and disability-adjusted life-years (DALYs); compared pre-2019 and post-2019 trajectories using joinpoint regression; characterized age- and sex-specific burden patterns; and quantified contributions of modifiable risk factors. Results: Age-standardized incidence increased 92%, from 251.7 (95% uncertainty interval [UI]: 231.5 to 272.4) to 482.5 (95% UI: 451.5 to 516.4) per 100,000, and prevalence more than doubled, from 5564 (95% UI: 5088 to 6024) to 11,247 (95% UI: 10,382 to 12,132) per 100,000. In 2023, males exhibited higher DALY rates than females in most adult age groups from age 15 years onward, shifting away from the female-predominant pattern seen in 1990; female rates remained higher at several of the oldest age groups. Children aged 0 to 14 years were the only group with declining DALY rates (?52% to ?57%). Post-2019 incidence was higher in 15 of 21 countries, and six countries had higher DALY trends with non-overlapping confidence intervals. Because we only have four to five years of data, these short trends are preliminary and require care when evaluating. High body-mass index was the leading modifiable risk factor. Conclusions: These data support country-specific prevention and chronic-care strategies across the MENA region. en-copyright= kn-copyright= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LescanoJudah Israel Ong en-aut-sei=Lescano en-aut-mei=Judah Israel Ong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwataNaohiro en-aut-sei=Iwata en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HigashionnaTsukasa en-aut-sei=Higashionna en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Hematology and Oncology, Mayo Clinic kn-affil= affil-num=5 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Faculty of Pharmacy, Haiphong University of Medicine and Pharmacy kn-affil= affil-num=8 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=GBD 2023 kn-keyword=GBD 2023 en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=Middle East and North Africa kn-keyword=Middle East and North Africa en-keyword=joinpoint regression kn-keyword=joinpoint regression en-keyword=cardiovascular risk factors kn-keyword=cardiovascular risk factors en-keyword=epidemiology kn-keyword=epidemiology en-keyword=public health kn-keyword=public health END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=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 ƒÀ-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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260820 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Performance of generative artificial intelligence in oral and maxillofacial radiology based on the board-certification examination of Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective To evaluate the performance and potential utility of generative artificial intelligence (AI) in oral and maxillofacial radiology using the board-certification examination administered by the Japanese Society for Oral and Maxillofacial Radiology (JSOMR).
Methods The responses generated by ChatGPT for multiple-choice questions from the board-certification examination of the JSOMR over the three-year period from 2020 to 2022 were assessed. The questions were manually entered individually as prompts for GPT-3.5, GPT-4, and GPT-5, which are the models available from ChatGPT. The accuracy was calculated according to examination year, question format, and level of taxonomy.
Results GPT-3.5 achieved an accuracy of 40.3% for the three years (42.9%, 42.0%, and 36.0% for 2020, 2021, and 2022, respectively), that of GPT-4 was 67.8% (67.3%, 74.0%, and 62.0%, respectively), and that of GPT-5 was 76.5% (79.6%, 78.0%, and 72.0%, respectively). GPT-5fs results exceeded the passing score for each year with the accuracy significantly outperformed that of GPT-3.5 and GPT-4. Regarding performance according to the question format, GPT-5 performed significantly superior to the earlier models, especially on two-answer questions.
Conclusions On the board-certification examination of the JSOMR, the performance of GPT-5 was significantly superior to that of GPT-3.5 and GPT-4. This suggests that, given the rapid development of generative AI, GPT-5 has reached a level of text-based knowledge equivalent to that assessed in the board-certification examination of the JSOMR. en-copyright= kn-copyright= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawazuToshiyuki en-aut-sei=Kawazu en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HisatomiMiki en-aut-sei=Hisatomi en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujikuraMamiko en-aut-sei=Fujikura en-aut-mei=Mamiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibanumaAkira en-aut-sei=Shibanuma en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NambaYuri en-aut-sei=Namba en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaSuzuka en-aut-sei=Yoshida en-aut-mei=Suzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakamuraYoshihide en-aut-sei=Nakamura en-aut-mei=Yoshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YanagiYoshinobu en-aut-sei=Yanagi en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=6 en-affil=Department of Community and Global Health, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Radiology, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=9 en-affil=Preliminary Examination Room, Medical Development Field, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Artificial intelligence kn-keyword=Artificial intelligence en-keyword=Generative artificial intelligence kn-keyword=Generative artificial intelligence en-keyword=ChatGPT kn-keyword=ChatGPT en-keyword=Large language model kn-keyword=Large language model en-keyword=Radiology kn-keyword=Radiology en-keyword=Education kn-keyword=Education END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=122947 end-page=122962 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=A Novel Approximate Solution Method for Euclidean Steiner Tree Problem Based on Genetic Algorithm en-subtitle= kn-subtitle= en-abstract= kn-abstract=A novel approximate solution method for the Euclidean Steiner tree problem is proposed and its performance is demonstrated through experiments using 195 benchmark problem instances from the OR-Library. Given a finite number of terminal points, the proposed method first generates non-terminal points around each terminal point and at the same location as the Steiner point for each triangle obtained by the Delaunay triangulation for all terminal points. It next runs a genetic algorithm to select a subset of the generated non-terminal points, aiming to minimize the total edge length of a minimum spanning tree for all the terminal points and the selected non-terminal points. It then optimizes the locations of the non-terminal points in the tree using Weiszfeldfs method, while preserving the topology. It finally refines the tree by adding new non-terminal points, adding and removing edges, and optimizing the locations of all non-terminal points. The experimental results show that, among 150 benchmark problem instances with known optimal solutions, the proposed method successfully constructs a Euclidean Steiner tree for 61 instances. For the remaining 89 instances, it produces an approximate solution whose total edge lengths is less than 100.7% of the optimal. The experimental results also show that the proposed method obtains approximate solutions efficiently: within 1.5 seconds for instances with up to 100 terminal points and within 61 seconds for instances with up to 1,000 terminal points. en-copyright= kn-copyright= en-aut-name=ZhangLiping en-aut-sei=Zhang en-aut-mei=Liping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MigitaTsuyoshi en-aut-sei=Migita en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiNorikazu en-aut-sei=Takahashi en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=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=Combinatorial optimization kn-keyword=Combinatorial optimization en-keyword=genetic algorithm kn-keyword=genetic algorithm en-keyword=Fermat problem kn-keyword=Fermat problem en-keyword=Weiszfeldfs method kn-keyword=Weiszfeldfs method en-keyword=Delaunay triangulation kn-keyword=Delaunay triangulation END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=1 article-no= start-page=97 end-page=112 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vaccination in paediatric, adolescent, and transitional-age rheumatic diseases: a systematic review 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=35 cd-vols= no-issue=2 article-no= start-page=159 end-page=169 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260811 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An interdisciplinary approach to sampling hard rock cores of the oceanic crust for microbiological and biogeochemical research en-subtitle= kn-subtitle= en-abstract= kn-abstract=Studying life in the deep, rocky subseafloor involves many layers of technological and methodological challenges, and each drilling project or expedition must make a series of choices to address these challenges. We report on the workflow for sampling hard rock cores for microbiological and biogeochemical research that was developed and optimized during International Ocean Discovery Program (IODP) Expedition 399. All steps of the workflow, including selection of the sample and its shipboard homogenization and subsampling for specific analyses, were designed to maximize the potential for interdisciplinary collaborations and syntheses of results. Furthermore, multiple strategies to minimize and detect potential microbial and organic chemical contamination of the core samples were employed, including the shipboard detection of a fluorescent chemical tracer pumped into the drill fluid. Contamination tracer levels were detectable on the exterior surfaces of the core but absent in the homogenized interiors of most core samples. Based on the experiences and preliminary results of this expedition, recommendations for processing samples on future expeditions are presented. en-copyright= kn-copyright= en-aut-name=BrazeltonWilliam J. en-aut-sei=Brazelton en-aut-mei=William J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CavazosOscar en-aut-sei=Cavazos en-aut-mei=Oscar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RobareJordyn A. en-aut-sei=Robare en-aut-mei=Jordyn A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SouthamGordon en-aut-sei=Southam en-aut-mei=Gordon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuhonenJohanna en-aut-sei=Suhonen en-aut-mei=Johanna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WangFengping en-aut-sei=Wang en-aut-mei=Fengping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LangSusan Q. en-aut-sei=Lang en-aut-mei=Susan Q. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=McCaigAndrew en-aut-sei=McCaig en-aut-mei=Andrew kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BlumPeter en-aut-sei=Blum en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AbeNatsue en-aut-sei=Abe en-aut-mei=Natsue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ColtatR?mi en-aut-sei=Coltat en-aut-mei=R?mi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DeansJeremy R. en-aut-sei=Deans en-aut-mei=Jeremy R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DickersonKristin L. en-aut-sei=Dickerson en-aut-mei=Kristin L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=GodardMarguerite en-aut-sei=Godard en-aut-mei=Marguerite kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=JohnBarbara E. en-aut-sei=John en-aut-mei=Barbara E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=KleinFrieder en-aut-sei=Klein en-aut-mei=Frieder kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=KuehnRebecca en-aut-sei=Kuehn en-aut-mei=Rebecca kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=LinKuan-Yu en-aut-sei=Lin en-aut-mei=Kuan-Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=LissenbergC.

Involvement of the small intestine is rare and is often overlooked as a source of obscure gastrointestinal bleeding. Because jejunal lymphangiomas frequently present with nonspecific symptoms and may escape detection by conventional upper and lower gastrointestinal endoscopy or cross-sectional imaging, diagnosis is often delayed. Advances in balloon-assisted enteroscopy have enabled direct visualization of small intestinal lesions, facilitating accurate diagnosis and appropriate therapeutic decision-making. Here, we report a case of jejunal lymphangioma presenting with severe anemia due to active bleeding, which was detected by double-balloon endoscopy and successfully managed by laparoscopic-assisted resection. This case highlights the importance of considering small intestinal lymphangioma in the differential diagnosis of unexplained gastrointestinal bleeding and underscores the clinical utility of deep enteroscopy in identifying rare but clinically significant small bowel tumors. en-copyright= kn-copyright= en-aut-name=IshikamiSachiko en-aut-sei=Ishikami en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=YamamotoNao en-aut-sei=Yamamoto en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoYuki en-aut-sei=Okamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimatsuRika en-aut-sei=Yoshimatsu en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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 General Medicine, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Radiology, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=jejunal lymphangioma kn-keyword=jejunal lymphangioma en-keyword=double-balloon endoscopy kn-keyword=double-balloon endoscopy en-keyword=surgery kn-keyword=surgery 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 tumorfs 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=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 patientsf 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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260727 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Workforce and institutional factors associated with comprehensive genomic profiling utilization in gynecologic oncology: a nationwide questionnaire survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Comprehensive genomic profiling (CGP) has been widely introduced into precision oncology; however, its real-world implementation in gynecologic oncology remains unclear. This study evaluated nationwide CGP utilization, treatment translation, and management of secondary germline findings in Japanese gynecologic oncology.
Methods A nationwide survey was conducted across 98 institutions participating in gynecologic oncology training and/or Japanfs cancer genomic medicine network. Institutional characteristics, workforce composition, treatment translation, and management of germline findings were assessed. Associations between institutional factors and CGP utilization or trial-related treatment translation were analyzed using incidence rate ratios (IRRs) with 95% confidence intervals.
Results Among 68 institutions with complete CGP volume data, 6,964 CGP tests were performed, including 922 for gynecologic malignancies. The median number of gynecologic CGP tests per institution was 10. In multivariate analysis, the number of board-certified obstetrician?gynecologists was associated with CGP utilization (IRR, 1.05; 95% CI 1.01?1.08). CGP-guided therapy was delivered to 80 patients (8.7%). Trial-related treatment translation was associated with the number of board-certified obstetrician?gynecologists (IRR, 1.09; 95% CI 1.02?1.16) and the presence of a medical oncology department (IRR, 7.93; 95% CI 1.41?44.72). Presumed germline pathogenic variants were identified in 100 cases (10.8%); however, confirmatory germline testing was performed in only 38 cases.
Conclusion CGP utilization in Japanese gynecologic oncology was associated with gynecologic workforce capacity and multidisciplinary genomic infrastructure. Collaboration between gynecologic oncology and medical oncology may facilitate treatment translation. CGP may also serve as an entry point for hereditary cancer evaluation despite incomplete downstream germline evaluation. en-copyright= kn-copyright= en-aut-name=SudoTamotsu en-aut-sei=Sudo

genes and their translation into twenty languages en-subtitle= kn-subtitle= en-abstract= kn-abstract=Genetic testing for cancer susceptibility underpins precision cancer prevention and care. Gaps in the healthcare providersf genetic literacy and an ambiguous lexicon for variant description may hinder proper delivery and clinical application of consistently trustworthy test results. The Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA) international consortium supports controlled terminology and recommends a framework for reporting germline variants in cancer susceptibility genes, using breast cancer as an exemplar. Moving forward towards terminological coherence across disciplines and borders, the ENIGMA Clinical Working Group launched a multinational effort to release consortium-approved translations of the published recommendations. The herein reported Vocabulary Translation Project offered an opportunity to reappraise and align the reference text to the recent BRCA1 and BRCA2 specifications to the American College of Medical Genetics and Genomics/Association for Molecular Pathology rules by the ENIGMA Variant Curation Expert Panel and to highlight country-specific differences in breast cancer risk assessment and management. The updated recommendations and their 20 translations are now provided as easy to handle documents, covering 11 of the most widely spoken languages in the world. They will contribute to minimised erroneous inferences, more informed decision-making, improved health outcomes and equity in the use of genetic testing for cancer predisposition and in translational oncology. en-copyright= kn-copyright= en-aut-name=De NicoloArcangela en-aut-sei=De Nicolo en-aut-mei=Arcangela kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EcclesDiana M

Methods: A total of 24 male C57BL/6J mice (6 weeks old) were allocated to control, periodontitis (P), BS, and BS+P groups. Periodontitis was induced by bilateral ligation of maxillary second molars, and BS was orally administered for 18 consecutive days. Gut microbiota composition was analyzed by 16S rDNA sequencing, alveolar bone loss and gut morphology were evaluated using ImageJ version 1.54g, and ELISA-detectable serum vitamin D metabolite concentrations were measured using an enzyme-linked immunosorbent assay. Results: Compared with the P group, the BS+P group showed reduced bone loss. Serum vitamin D metabolite concentrations, small-intestine villus height, and villus height-to-crypt depth ratios were higher in the BS+P group. In gut microbiota, alpha diversity differed significantly among groups based on the Shannon index. Bray?Curtis-based beta diversity differed significantly among groups. Conclusions: Oral supplementation of BS attenuated the progression of ligature-induced periodontitis in a mouse model, and changes in gut microbiota may be associated with this effect. en-copyright= kn-copyright= en-aut-name=ZhangYixuan en-aut-sei=Zhang en-aut-mei=Yixuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NurhamimMohammad en-aut-sei=Nurhamim en-aut-mei=Mohammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaMomoko en-aut-sei=Nakahara en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukuharaDaiki en-aut-sei=Fukuhara en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Dental School, Okayama University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Dental School, Okayama University kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Academic Field of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Bacillus subtilis kn-keyword=Bacillus subtilis en-keyword=periodontitis kn-keyword=periodontitis en-keyword=alveolar bone loss kn-keyword=alveolar bone loss en-keyword=gut microbiota kn-keyword=gut microbiota en-keyword=intestinal morphology kn-keyword=intestinal morphology en-keyword=vitamin D kn-keyword=vitamin D en-keyword=mouse model kn-keyword=mouse model END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue=11 article-no= start-page=19516 end-page=19529 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=Structural Design of Litz Wires for Reducing AC Transport Current Loss Using an Equivalent Circuit Model Considering the Path of All Strands en-subtitle= kn-subtitle= en-abstract= kn-abstract=Litz wires are generally fabricated based on the proprietary know-how of wire manufacturers. Therefore, the design guidelines for the conductor structure of low-loss Litz wires have not been clearly established. In this study, we investigated the effect of differences in the conductor structure on the AC resistance using the equivalent circuit model considering the path of all strands. Moreover, we proposed design guidelines for the conductor structure of Litz wires to reduce AC resistance originating from strand paths. Furthermore, we prototyped Litz wires according to the proposed design guidelines and compared the AC resistance of the proposed Litz wires with that of commercial Litz wires. As a result, the AC resistance of the prototyped Litz wires according to the proposed design guidelines was reduced compared to that of the commercial Litz wires. Moreover, the quality factor of the spiral coil using the proposed Litz wire was higher than that using the commercial Litz wire. From the above results, we experimentally clarified that the proposed design guidelines for the conductor structure of Litz wires are effective in reducing the AC resistance originating from strand paths. en-copyright= kn-copyright= en-aut-name=InoueRyota en-aut-sei=Inoue en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UedaHiroshi en-aut-sei=Ueda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimSeokBeom en-aut-sei=Kim en-aut-mei=SeokBeom kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environment, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environment, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environment, Life, Natural Science, and Technology, Okayama University kn-affil= en-keyword=AC resistance kn-keyword=AC resistance en-keyword=copper loss kn-keyword=copper loss en-keyword=equivalent circuit kn-keyword=equivalent circuit en-keyword=Litz wire kn-keyword=Litz wire en-keyword=spiral coil kn-keyword=spiral coil END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue= article-no= start-page=102156 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=Pembrolizumab-based systemic therapy associated with opportunities for subsequent local treatment in advanced or recurrent neuroendocrine carcinoma of the cervix: a five-case series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Neuroendocrine carcinoma (NEC) of the cervix is a rare, highly aggressive malignancy with limited evidence supporting immune checkpoint blockade. We evaluated the clinical activity of pembrolizumab-based therapy in patients with advanced or recurrent cervical NEC.
Methods: We retrospectively reviewed five consecutive patients with advanced or recurrent cervical NEC treated with pembrolizumab-based therapy at Okayama University Hospital between November 2022 and April 2025. Clinical characteristics, radiologic responses, molecular profiles, adverse events, local treatments, and survival outcomes were analyzed.
Results: The median age was 52 years. Three patients had newly diagnosed stage IVB disease, and two had recurrent metastatic disease after radical surgery and postoperative irinotecan plus cisplatin chemotherapy. All patients received paclitaxel plus carboplatin with pembrolizumab. An objective response was observed in all patients, including one complete response and four partial responses according to RECIST version 1.1. The median maximum tumor shrinkage was 78.5%, and median progression-free survival was 10.0 months. Comprehensive genomic profiling in four patients showed microsatellite-stable tumors with low tumor mutational burden in all evaluated cases. HPV association was supported by HPV16/18 sequences in three patients and diffuse p16 expression in one additional patient. Immune-related adverse events were grade 2 or lower. In three patients, systemic disease control allowed subsequent local treatment, including radiotherapy, conversion surgery, and stereotactic radiotherapy.
Conclusion: Pembrolizumab-based therapy showed encouraging clinical activity despite microsatellite-stable status and low tumor mutational burden in evaluated cases. Sustained systemic disease control may provide an opportunity for multimodal treatment incorporating subsequent local treatment. en-copyright= kn-copyright= en-aut-name=IdaNaoyuki en-aut-sei=Ida en-aut-mei=Naoyuki 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=TanakaYui en-aut-sei=Tanaka en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=TaniokaMomoko en-aut-sei=Tanioka en-aut-mei=Momoko 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=MatsuokaHirofumi en-aut-sei=Matsuoka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=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=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Neuroendocrine carcinoma (NEC) kn-keyword=Neuroendocrine carcinoma (NEC) en-keyword=Cervical cancer kn-keyword=Cervical cancer en-keyword=Pembrolizumab kn-keyword=Pembrolizumab en-keyword=Immunotherapy kn-keyword=Immunotherapy en-keyword=Local intervention kn-keyword=Local intervention en-keyword=Case series kn-keyword=Case series END start-ver=1.4 cd-journal=joma no-vol=91 cd-vols= no-issue= article-no= start-page=103582 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=Does ESG performance enhance investment efficiency and firm performance? Evidence from Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examines the association between investment sensitivity to growth opportunities, firm performance, and environmental, social, and governance (ESG) performance in Japanese listed firms. To determine whether ESG performance is associated with a firmfs investment sensitivity to growth opportunities rather than directly increasing investment levels, panel data covering the period from 2002 to 2023 and an investment-Q sensitivity framework are employed. To evaluate robustness and reduce endogeneity issues, high-dimensional fixed effects (HDFE), the System Generalized Method of Moments (GMM), and a difference-in-differences (DID) design based on Japanfs post-2015 governance and disclosure environment are added to the baseline fixed-effects estimations. The findings show a positive association between investment-Q sensitivity and ESG performance, indicating a conditional association wherein firms with higher ESG performance are more receptive to expansion prospects. The findings, however, contradict the hypothesis that ESG performance and investment intensity are consistently associated. Stricter identification techniques diminish positive baseline associations, demonstrating sensitivity to model specification and cross-sectional firm variations. As a result, firm performance results are mixed. Governance-related factors are comparatively more consistently associated with investment outcomes across all ESG components. By focusing on ESG performance and capital allocation behavior under various economic scenarios rather than on whether ESG generally enhances firm outcomes, this study expands the ESG literature. The results imply that ESG serves more as a governance and information mechanism associated with investment sensitivity than as a reliable indicator of firm performance or investment efficiency. en-copyright= kn-copyright= en-aut-name=NazirYusra en-aut-sei=Nazir en-aut-mei=Yusra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CaiXiaojing en-aut-sei=Cai en-aut-mei=Xiaojing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TennojiyaTatsumasa en-aut-sei=Tennojiya en-aut-mei=Tatsumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=ESG performance kn-keyword=ESG performance en-keyword=Investment efficiency kn-keyword=Investment efficiency en-keyword=Firm performance kn-keyword=Firm performance en-keyword=Return on assets kn-keyword=Return on assets en-keyword=Asset turnover kn-keyword=Asset turnover en-keyword=Corporate sustainability kn-keyword=Corporate sustainability en-keyword=Japanese firms kn-keyword=Japanese firms 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=66 cd-vols= no-issue=2 article-no= start-page=122 end-page=129 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=RHOA G17V mutation analysis redirecting diagnosis: nodal T-follicular helper cell lymphoma with classic Hodgkin lymphoma feature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nodal T-follicular helper cell lymphoma (nTFHL) may present with Hodgkin/Reed?Sternberg (HRS)-like cells and can morphologically mimic classic Hodgkin lymphoma (CHL), although these entities are usually distinguishable. We report an unusual case showing marked morphologic and molecular overlap with CHL, creating a diagnostic challenge but ultimately considered biologically consistent with nTFHL.
An 81-year-old woman presented with stage IV disease involving the bone marrow and markedly elevated serum soluble interleukin-2 receptor levels. Excisional lymph node biopsy revealed scattered HRS cells in a T-cell?rich background, with strong CD30 and PD-L1 expression and weak PAX5 positivity, findings consistent with CHL. Fluorescence in situ hybridization demonstrated copy-number alterations at the 9p24.1 locus in HRS cells, further supporting molecular features characteristic of CHL.
However, the presence of two T-follicular helper markers, detection of the RHOA p.Gly17Val (G17V) mutation, and oligoclonal T-cell receptor rearrangements with shared peaks in lymph node and bone marrow indicated an underlying nTFHL. The differential therapeutic response also supported a diagnosis of nTFHL, which could not have been established on morphology alone.
In this case, although the HRS cells displayed morphological, immunophenotypic, and molecular features highly suggestive of CHL, the biological nature of the lesion was consistent with nTFHL. Compared with previously reported cases of nTFHL with HRS-like cells, this case more closely resembled CHL and may represent a distinct subset best described as gnTFHL with CHL features,h a concept warranting greater recognition among pathologists and clinicians. en-copyright= kn-copyright= en-aut-name=YamadaRio en-aut-sei=Yamada en-aut-mei=Rio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukumiTakuya en-aut-sei=Fukumi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhsawaKumiko en-aut-sei=Ohsawa en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MomoseShuji en-aut-sei=Momose en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Hematology, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Saitama Medical Center, Saitama Medical University kn-affil= affil-num=6 en-affil=Department of Pathology, Saitama Medical Center, Saitama Medical University kn-affil= affil-num=7 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=classic Hodgkin lymphoma kn-keyword=classic Hodgkin lymphoma en-keyword=nodal T-follicular helper cell lymphoma kn-keyword=nodal T-follicular helper cell lymphoma en-keyword=RHOA mutation kn-keyword=RHOA mutation END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=e79001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Durable Response to Nivolumab Combined With Metformin in Advanced Pancreatic Cancer: A Case Report With Seven Years of Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of poorly differentiated pancreatic cancer that showed an exceptional response to combination therapy with nivolumab and metformin. A 58-year-old man presented with epigastric pain and was diagnosed with locally advanced pancreatic cancer with para-aortic lymph node metastasis. After disease progression following modified FOLFIRINOX therapy (a combination of fluorouracil, leucovorin, irinotecan, and oxaliplatin), the patient was enrolled in a phase Ib clinical trial of nivolumab (3 mg/kg biweekly) combined with metformin (750 mg/day). Post-treatment imaging showed marked tumor shrinkage with normalization of the tumor markers. During treatment, the patient was diagnosed with early-stage lung cancer and underwent successful left S1+S2 segmentectomy with temporary suspension of immunotherapy. The therapeutic response of pancreatic cancer has been sustained for seven years, with minimal residual disease. This unprecedented response duration is particularly noteworthy considering his microsatellite stability, which typically predicts a limited response to immune checkpoint inhibition.
This case demonstrates an exceptional response to nivolumab and metformin combination therapy in poorly differentiated pancreatic cancer. The remarkable durability of the response suggests the need for further investigation to identify patients most likely to benefit from this therapeutic approach. en-copyright= kn-copyright= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KozukiToshiyuki en-aut-sei=Kozuki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UdonoHeiichiro en-aut-sei=Udono en-aut-mei=Heiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama City Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine and Allergology, Kochi Medical School, Kochi University kn-affil= affil-num=8 en-affil=Department of Immunology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=immune checkpoint inhibitors kn-keyword=immune checkpoint inhibitors en-keyword=immunotherapy kn-keyword=immunotherapy en-keyword=metformin kn-keyword=metformin en-keyword=nivolumab kn-keyword=nivolumab en-keyword=pancreatic cancer kn-keyword=pancreatic cancer END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=e80184 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cholecystectomy Is Linked to Worse Clinical Outcomes in Primary Sclerosing Cholangitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent findings have suggested that gallbladder-derived retinoic acid signaling plays a crucial role in the regeneration of damaged intrahepatic biliary ducts. This retrospective cohort study analyzed the clinical records of 20 patients with primary sclerosing cholangitis (PSC) treated at our hospital between 2013 and 2024. We investigated the clinical implications of gallbladder removal in patients with PSC, a progressive cholangiopathy with limited therapeutic options. We retrospectively analyzed the data of patients with PSC and compared patients with and without prior cholecystectomy to assess the impact on disease progression using the Mayo risk score, Fibrosis-4 (FIB4) index, and other clinical parameters. Our findings indicated that cholecystectomy was associated with worse Mayo risk scores (p = 0.0004) and an elevated FIB4 index (p = 0.021), suggesting a potential link between gallbladder removal and accelerated disease progression. Furthermore, mortality and transplant-free survival analysis revealed significantly worse outcomes in the cholecystectomy group (odds ratio = 21.0, p = 0.032). However, given the retrospective nature and small sample size of this study, selection bias cannot be excluded, and further research is needed to confirm these findings. These findings support the hypothesis that gallbladder-derived factors, such as retinoic acid, may influence PSC progression and highlight the need for further research into therapeutic interventions targeting this pathway. en-copyright= kn-copyright= en-aut-name=MiyakeNozomi en-aut-sei=Miyake en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasugiKengo en-aut-sei=Yasugi en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University kn-affil= en-keyword=biliary diseases kn-keyword=biliary diseases en-keyword=cholecystectomy kn-keyword=cholecystectomy en-keyword=gall bladder kn-keyword=gall bladder en-keyword=liver function kn-keyword=liver function en-keyword=post cholecystectomy kn-keyword=post cholecystectomy en-keyword=primary sclerosing cholangitis (psc) kn-keyword=primary sclerosing cholangitis (psc) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=8 article-no= start-page=e66069 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A New Minimally Invasive Technique for Thoracolumbar/Lumbar Focal Kyphosis Due to Osteoporotic Vertebral Fracture: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osteoporotic vertebral fractures are common fractures in the elderly population and are often associated with low back pain and disruption in daily living activities. Reconstruction surgeries, such as corpectomy, are among the treatment options for these conditions. However, a corpectomy requires a longer surgical procedure and involves a significant amount of blood loss. We present the case of an 80-year-old woman with severe low back pain due to an L2 fracture and focal kyphosis treated with a novel minimally invasive technique. The patient underwent anterior and posterior surgery in the right decubitus position using a C-arm-free technique. Hyperlordotic cages were inserted in the upper and lower disc space via a lateral approach, while percutaneous pedicle screws were inserted from a posterior approach. These procedures were performed simultaneously under navigation guidance only. 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=Al AskarAbd El Kader en-aut-sei=Al Askar en-aut-mei=Abd El Kader kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EkadeShashank J en-aut-sei=Ekade en-aut-mei=Shashank J 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=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=oblique lumbar interbody fusion kn-keyword=oblique lumbar interbody fusion en-keyword=novel technique kn-keyword=novel technique en-keyword=c-arm free kn-keyword=c-arm free en-keyword=thoracolumbar focal kyphosis kn-keyword=thoracolumbar focal kyphosis en-keyword=osteoporotic vertebral fractures kn-keyword=osteoporotic vertebral fractures END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=e81104 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Pemafibrate and Eicosapentaenoic Acid Ethyl Ester on Endothelial Function in Patients With Hypertriglyceridemia and Coronary Artery Disease: A Study Protocol for a Multicenter, Open-Label Randomised Controlled Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite intensive low-density lipoprotein cholesterol-lowering therapies effectively reducing cardiovascular events, residual cardiovascular risks remain significant, with hypertriglyceridemia being an important contributing factor.

The PRIME (PRospective comparIson of peMafibrate and Eicosapentaenoic acid ethyl ester on vascular functions for hypertriglyceridemia) trial is a multi-center, open-label, randomised trial designed to compare the effects of pemafibrate and EPA on endothelial function in patients with CAD and hypertriglyceridemia. Patients receiving statin therapy with fasting triglyceride levels ?150 mg/dL will be randomised into two groups: pemafibrate (0.2 mg/day, with possible dose escalation to 0.4 mg/day) or EPA (1800 mg/day, with possible dose escalation to 2700 mg/day). Endothelial function will be assessed with reactive hyperemia index (RHI). The primary endpoint is the change in RHI at 12 weeks. The secondary endpoints include the changes in RHI at 24 weeks, correlations between changes in RHI and changes in lipid biomarkers, and changes in biochemical parameters at 12 and 24 weeks. This study investigates the comparative effects of pemafibrate and EPA on endothelial function, addressing an unmet need in managing residual cardiovascular risk in patients with CAD. The findings will contribute to the optimisation of treatment strategies in patients with CAD and hypertriglyceridemia. en-copyright= kn-copyright= en-aut-name=MiyoshiTrou en-aut-sei=Miyoshi en-aut-mei=Trou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuzawaYasushi en-aut-sei=Matsuzawa en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DoiMasayuki en-aut-sei=Doi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SugiyamaSeigo en-aut-sei=Sugiyama en-aut-mei=Seigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Cardiovascular Medicine, Okayama University kn-affil= affil-num=2 en-affil=Cardiovascular Medicine, Kumamoto University kn-affil= affil-num=3 en-affil=Cardiology, Kagawa Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Cardiovascular Medicine, Okayama University kn-affil= affil-num=5 en-affil=Cardiovascular Medicine, Jinnouchi Hospital kn-affil= en-keyword=cardiovascular risk kn-keyword=cardiovascular risk en-keyword=eicosapentaenoic acid kn-keyword=eicosapentaenoic acid en-keyword=endothelial function kn-keyword=endothelial function en-keyword=pemafibrate kn-keyword=pemafibrate en-keyword=triglyceride kn-keyword=triglyceride END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=9 article-no= start-page=e70066 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decreased CD3+CD56+ Natural Killer T Lymphocytes and Increased Human Leukocyte Antigen-DR+ Cells in the Inflamed Area of Pouchitis in Ulcerative Colitis Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pouchitis is an inflammatory condition that affects the ileal pouch during ileal pouch-anal anastomosis surgery. Despite its clinical significance, precise immunological mechanisms underlying pouchitis remain unclear. This study aimed to investigate the lymphocyte profile in the ileal pouch of patients with pouchitis compared to those with familial adenomatous polyposis (FAP) and ulcerative colitis without pouchitis using flow cytometry and immunohistochemical techniques.
Methods: We prospectively analyzed endoscopic biopsy specimens from the ileal pouches of 15 patients and categorized them into three groups: FAP, ulcerative colitis with an inflammation-free pouch (UC-I), and ulcerative colitis with ulcers and/or erosions in the pouch (UC-UE). Flow cytometry was used to assess various T-lymphocyte markers, including cluster of differentiation (CD) 4, CD8, CD56, and human leukocyte antigen (HLA)-DR. Immunohistochemistry was performed to visualize the spatial distribution of CD3+, CD56+, and HLA-DR+ cells in the pouch mucosa.
Results: We observed significantly reduced CD56+/CD3+ and CD8+/CD3+ ratios in the UC-UE group compared to those in the FAP group, indicating a disruption in natural killer T-cell populations. Immunohistochemical analysis revealed that the spatial distribution of lymphocytes differed among the non-inflamed mucosa, dense lymphocyte infiltration, and lymphoid follicles, with these components frequently intermingling. CD56 + cells were less abundant in areas with dense lymphocyte infiltration, whereas HLA-DR+ cells were more abundant.
Conclusion: Our study revealed a decrease in CD56+ natural killer T cells and an increase in HLA-DR+-activated T cells in areas with dense lymphocyte infiltration, suggesting an association between these cells and pouchitis in ulcerative colitis. The distinct patterns observed in non-inflamed mucosa, areas with dense lymphocyte infiltration, and lymphoid follicles underscore the need for further analyses of these three segments to elucidate the immunological mechanisms underlying pouchitis. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=flow cytometry kn-keyword=flow cytometry en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=lymphocytes, pouchitis kn-keyword=lymphocytes, pouchitis en-keyword=ulcerative colitis kn-keyword=ulcerative colitis END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=8 article-no= start-page=e91242 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of Ibuprofen Gargle for Oral Lichen Planus: A Single-Center, Placebo-Controlled, Double-Blind, Randomized Crossover Study Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Oral lichen planus (OLP) is a chronic, refractory type of stomatitis characterized by abnormal keratinization and often accompanied by pain. The best treatment for OLP, particularly for pain management, remains unclear. This study focuses on the short-term efficacy of ibuprofen gargle for pain relief in patients with OLP.
Methods: In this crossover study, 24 patients with painful OLP were enrolled. One group received an ibuprofen gargle (0.6%) on days one and three to five and a placebo on day two. The other group received a placebo on day one and ibuprofen on days two to five. The primary outcome was the change in pain level, measured by a Visual Analogue Scale (VAS) before and after gargling on days one and two. Additionally, changes in each domain of the Patient-Reported Oral Mucositis Symptom (PROMS) scale were evaluated from days one to five.
Results: There was no significant difference in the degree of reduction in pain VAS values between the ibuprofen and placebo groups before and five and 15 minutes after use of the gargle. However, the PROMS scale showed a significant reduction in dietary restrictions (p = 0.032) in favor of the ibuprofen gargle compared to baseline.
Conclusion: Ibuprofen gargle may help alleviate dietary restrictions associated with oral intake in patients with OLP who experience pain.

The brace therapy for adolescent idiopathic scoliosis (AIS) typically ends upon the end of growth. However, determining the timing of growth cessation can be challenging. The purpose of this study was to evaluate the utility of the proximal femur maturity index (PFMI), which can be assessed simultaneously with Risser staging without requiring additional radiation exposure, in determining the appropriate timing to terminate bracing. To achieve this, we investigated the relationship between skeletal maturity at the end of bracing, post-bracing curve progression, and height growth in patients who had been successfully treated with a brace.
Methods
Between April 2010 and March 2021, a total of 84 female patients with AIS who started bracing at our hospital with an initial Cobb angle of 20-40 degrees were included. All patients were followed for at least one year after brace termination. Height and radiographic parameters (Risser staging, PFMI, Cobb angle) were retrospectively collected.
Results
At the end of the bracing period, patients were categorized into Risser stage 4 (85.7%) and 5 (14.3%). By the last follow-up, patients with Risser stage 4 experienced an average main curve progression of 1.8‹, whereas those with Risser stage 5 had an average progression of ?0.3‹ (P = 0.03). Patients with Risser stage 4 were further divided into PFMI grade 5 (59.7%) and 6 (40.3%). Significant curve progression was observed in patients with PFMI grade 5 (average: 3.0‹) compared to grade 6 (average: -0.6‹) (P < 0.0001). The mean height growth was 1.9 cm/year for PFMI grade 5, and 0.3 cm/year for grade 6, with significant differences between these groups (P < 0.001).
Conclusions
PFMI allowed further categorization within Risser stage 4: PFMI grade 5 indicated remaining growth potential and risk of postbracing curve progression, whereas grade 6 indicated growth cessation. The combined use of Risser staging and PFMI, both evaluable through the same whole-spine radiograph, may provide a more accurate prediction of growth cessation. en-copyright= kn-copyright= en-aut-name=ShitozawaHisakazu en-aut-sei=Shitozawa en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UedaMasataka en-aut-sei=Ueda en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakatoriRyo en-aut-sei=Takatori en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamashitaKazutaka en-aut-sei=Yamashita en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, 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 Orthopaedic Surgery, Ryusou Orthopaedic Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 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=8 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=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= affil-num=10 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=adolescent idiopathic scoliosis (ais) kn-keyword=adolescent idiopathic scoliosis (ais) en-keyword=height growth kn-keyword=height growth en-keyword=proximal femur maturity index kn-keyword=proximal femur maturity index en-keyword=risser staging kn-keyword=risser staging en-keyword=skeletal maturation kn-keyword=skeletal maturation END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=11 article-no= start-page=e73778 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessment of All-Inside Sutures to the Posteromedial Capsule in Medial Meniscus Posterior Root Repair: Findings From a Retrospective Three-Dimensional Magnetic Resonance Imaging Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Medial meniscus (MM) posterior root tears (PRT) cause pathological medial extrusion (MMME) and posterior extrusion (MMPE), particularly during knee flexion, leading to rapidly progressive knee osteoarthritis. We investigated pre- and postoperative MM extrusion using three-dimensional open magnetic resonance imaging (MRI) following two pullout repair techniques: two simple stitches (TSS) and TSS with an additional all-inside suture to the posteromedial capsule (TSS-PM). We hypothesized that TSS-PM would decrease MM extrusion more effectively than TSS.
Methods: Thirty patients who underwent MM posterior root repair were retrospectively evaluated. TSS and TSS-PM techniques were used for pullout repair. Open MRI was performed at 10/90‹ of knee flexion preoperatively and three months postoperatively. MMME, MMPE, and MM extrusion volume (MMEV) were measured and compared between groups.
Results: At 90‹ of knee flexion, postoperative MMPE and MMEV were significantly decreased compared to preoperative values in both the TSS and TSS-PM groups. Furthermore, a significantly decreased ƒ¢MMPE was observed in the TSS group compared to the TSS-PM group, whereas no significant difference was observed in ƒ¢MMEV.
Conclusion: TSS and TSS-PM repair techniques helped decrease MMEV at 90‹ of knee flexion, whereas a significantly decreased ƒ¢MMPE was observed in the TSS group at 90‹ of knee flexion. An additional all-inside suture at the posteromedial capsule may be insufficient to decrease MMEV and may negatively affect the decrease in ƒ¢MMPE at 90‹ of knee flexion. en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HasegawaTsubasa en-aut-sei=Hasegawa en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging en-keyword=medial meniscus extrusion kn-keyword=medial meniscus extrusion en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=pullout repair technique kn-keyword=pullout repair technique en-keyword=three-dimensional reconstruction kn-keyword=three-dimensional reconstruction END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=7 article-no= start-page=e70673 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=Potential of quantitative X]ray imaging from photon]counting CT: A novel analysis based on effective atomic number and physical density en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Conventional CT assessment of lung lesions is based mainly on morphological features. CT values represent relative X-ray attenuation that does not directly reflect tissue composition and/or physical density. Quantitative imaging using photon-counting CT (PC-CT) has the potential to provide quantitative parameters, such as effective atomic number (Zeff) and effective physical density (ƒÏeff).
Purpose: The purpose is to develop and demonstrate the potential of an algorithm that generates both the Zeff and ƒÏeff images, derived directly from virtual monoenergetic images (VMIs) acquired with a clinical PC-CT system.
Methods: The ƒÏeff image was generated by fitting a database of mass attenuation coefficients (ƒÊ/ƒÏ) to the measured linear attenuation coefficients (ƒÊ), which were obtained from two VMIs at 70 and 100 keV. As an effective material, Zeff information was also determined and fed back into the ƒÏeff calculation. An in-house low-density phantom was scanned for quantitative evaluation of ƒÏeff. In addition, to demonstrate the applicability of our procedure to actual clinical imaging, representative chest PC-CT images from patients were analyzed.
Results: In experiments using low-density phantoms, the CT values did not necessarily correlate with Zeff values, but they showed a very good correlation with the ƒÏeff values. The ƒÏeff values calculated using our procedure correlated well with the correct values of ƒÏ. A relative root mean square error of ƒÏeff calculation was 5.5%. Furthermore, we found that in pulmonary diagnosis, image contrast information from ƒÏeff makes it easier to identify and distinguish lesions compared to that from Zeff.
Conclusions: The proposed procedure directly generated Zeff and ƒÏeff images from PC-CT data and enabled quantitative interpretation of CT value in terms of elemental composition and physical density. In this study, the feasibility of generating Zeff and ƒÏeff images was demonstrated. en-copyright= kn-copyright= en-aut-name=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi 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=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitaniMana en-aut-sei=Mitani en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=3 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=College of Transdisciplinary Sciences for Innovation Kanazawa University Kanazawa Ishikawa Japan kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=density image kn-keyword=density image en-keyword=photon-counting kn-keyword=photon-counting en-keyword=virtual monoenergetic image kn-keyword=virtual monoenergetic image en-keyword=X-ray diagnosis kn-keyword=X-ray diagnosis END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=7 article-no= start-page=e70221 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=Photochemical Oxidative Esterification of Aldehydes with Radical-Sensitive Alcohols via C?H Bromination en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photochemical esterification is an attractive strategy for the synthesis of multifunctionalized esters, and the use of aldehydes as substrates offers an alternative to conventional carboxylic acid?based approaches. In particular, reactions via acyl halide intermediates are useful for accessing functionalized esters; however, examples of such transformations remain limited so far, and their compatibility with radical-sensitive alcohols remains relatively unexplored. Here, we report a photochemical oxidative esterification of aldehydes with radical-sensitive alcohols enabled by C?H bromination. This reaction proceeds without stoichiometric additives, such as bases, and enables the incorporation of a broad range of radical-sensitive functional groups into esters. Thus, it represents a promising platform for the synthesis of pharmaceuticals and functional materials. en-copyright= kn-copyright= en-aut-name=HariyantoNova Alfian en-aut-sei=Hariyanto en-aut-mei=Nova Alfian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AndoHaru en-aut-sei=Ando en-aut-mei=Haru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyamotoAtsuya en-aut-sei=Miyamoto en-aut-mei=Atsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta 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=C„ŸH bromination kn-keyword=C„ŸH bromination en-keyword=esterification kn-keyword=esterification en-keyword=photochemical synthesis kn-keyword=photochemical synthesis en-keyword=radical reaction kn-keyword=radical reaction END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=5 article-no= start-page=104504 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of initial interface formation time with CD34+ collection efficiency in continuous mononuclear cell collection: A retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Factors influencing CD34+ cell collection efficiency (CE) during peripheral blood stem cell harvesting have been investigated; however, the impact of procedural management remains unclear. In continuous mononuclear cell (CMNC) collection, a stable cell?plasma interface (IF) is formed through channel priming, initial IF establishment, and mononuclear cell (MNC) collection. Although IF instability is known to impair CE, the adequacy of initial IF formation has not been examined as an independent factor. Therefore, we focused on the time required for initial IF formation and its association with CE.
Methods: We retrospectively analyzed 291 Spectra Optia CMNC procedures (52 autologous and 239 allogeneic) performed between 2016 and 2025. Initial interface formation time (IFT) was defined as the interval from the start of the procedure to transition to MNC collection. CE2 was defined as the ratio of collected CD34+ cells to the product of pre-apheresis peripheral blood CD34+ cell concentration and processed blood volume. Results: CE2 was lower in autologous than in allogeneic collections (41.3% vs. 59.2%) and was associated with longer IFT (median, 18 vs. 15?min). CE2 correlated with white blood cell count (r?=??0.24), hematocrit (r?=?0.36), and IFT (r?=??0.23; all p? Conclusion: IFT is independently associated with CE2 and provides insight into the early dynamics of IF formation during leukapheresis, highlighting an underexplored procedural aspect of CE. en-copyright= kn-copyright= en-aut-name=MurakamiHiroyuki en-aut-sei=Murakami en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkeuchiKazuhiro en-aut-sei=Ikeuchi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimonoJoji en-aut-sei=Shimono en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology, Okayama University Hospital kn-affil= en-keyword=CD34+CE2 kn-keyword=CD34+CE2 en-keyword=Continuous mononuclear cell collection kn-keyword=Continuous mononuclear cell collection en-keyword=Spectra Optia kn-keyword=Spectra Optia en-keyword=Interface formation time kn-keyword=Interface formation time en-keyword=Leukapheresis kn-keyword=Leukapheresis END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=7 article-no= start-page=286 end-page=289 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=Ultra-Low Input Power Drivable IoT Wireless Sensor using Energy Harvesting from 2.45 GHz Wi-Fi en-subtitle= kn-subtitle= en-abstract= kn-abstract=This letter implements an ultra-low-power IoT wireless sensor driven by energy harvesting (EH) from 2.45 GHz Wi-Fi and verifies its performance. First, a planar Yagi-Uda antenna was used to extend transmission distance, and its maximum gain was 12.2 dBi. Next, a high-conversion-efficiency rectifier was implemented using surface-mount components to achieve ultra-low input power operation and achieved 15.7% conversion efficiency at ?20 dBm input power. Finally, connecting these components to the sensor module enabled sensor operation at a distance of 3.0 m from the Wi-Fi router. This shows that the proposed IoT wireless sensor offers high flexibility and enables semi-permanent operation. en-copyright= kn-copyright= en-aut-name=WadahamaMasato en-aut-sei=Wadahama en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimoriKazuhiro en-aut-sei=Fujimori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=RF energy harvesting kn-keyword=RF energy harvesting en-keyword=planar Yagi-Uda antenna kn-keyword=planar Yagi-Uda antenna en-keyword=rectifier kn-keyword=rectifier en-keyword=ultra-low power kn-keyword=ultra-low power en-keyword=IoT kn-keyword=IoT END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=7 article-no= start-page=1527 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Upregulation of the Outer Membrane Protein OmpV and Its Role in Polymyxin B Stress Adaptation in Vibrio mimicus en-subtitle= kn-subtitle= en-abstract= kn-abstract=OmpV is an outer membrane protein found in a variety of Gram-negative bacteria. In this study, we demonstrated that V. mimicus strain CS-66, isolated from a patient with diarrhea, was resistant to polymyxin B (PL-B) and colistin (CL) but susceptible to chloramphenicol and ciprofloxacin. When strain CS-66 was cultured in Luria?Bertani broth containing a sub-minimal inhibitory concentration of each antibiotic used for the susceptibility tests, ompV expression as assayed by reverse transcription-qPCR, significantly increased regardless of the antibiotic tested. In contrast, cell aggregation during the early log phase was observed only when the strain was grown in the broth supplemented with PL-B or CL. A space-filling model of V. mimicus OmpV was generated. The model showed that, although OmpV adopted a ƒÀ-barrel conformation, it had closed top and bottom ends and possessed a lateral cavity. Structural analysis further indicated that the interior of this lateral cavity was negatively charged and sufficiently large to accommodate PL-B. These results suggest that V. mimicus may adapt to PL-B stress through physical sequestration within the negatively charged cavity of OmpV. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=OnoderaYuta en-aut-sei=Onodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnnoiShunki en-aut-sei=Annoi en-aut-mei=Shunki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ImamuraDaisuke en-aut-sei=Imamura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=5 en-affil=Research Institute of Nursing Care for People and Community, University of Hyogo kn-affil= en-keyword=Vibrio mimicus kn-keyword=Vibrio mimicus en-keyword=polymyxin B kn-keyword=polymyxin B en-keyword=OmpV kn-keyword=OmpV en-keyword=ƒÀ-barrel protein kn-keyword=ƒÀ-barrel protein en-keyword=antibiotic sequestration kn-keyword=antibiotic sequestration 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=127 cd-vols= no-issue= article-no= start-page=111090 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=Outcome-aware and interpretable subtyping of chronic kidney disease: an analysis of the FROM-J study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic kidney disease (CKD) affects approximately 10% of the global population and exhibits substantial heterogeneity in disease progression and clinical outcomes. Despite ongoing efforts to develop new therapeutic strategies, the number of patients progressing to end-stage kidney disease (ESKD) and the incidence of cardiovascular disease (CVD) continue to rise. Although severity classification systems for CKD are well established and refined, they remain insufficient to capture prognostically relevant patient subtypes. In this study, we developed an outcome-aware and interpretable clustering framework for CKD subtyping using data from the FROM-J cohort with prognostic follow-up. A supervised XGBoost model was first trained to predict a ? 30% decline in estimated glomerular filtration rate (eGFR), a surrogate marker of CKD progression. SHAP (SHapley Additive exPlanations) values derived from this model were then used to quantify outcome-relevant feature contributions. Based on these feature attributions, a similarity graph was constructed, and spectral clustering was performed to identify patient subtypes driven by prognostic relevance. The proposed framework identified four CKD subtypes with distinct baseline clinical characteristics and significantly different risks of renal replacement therapy (RRT) and cardiovascular disease (CVD) events. Serum albumin, blood urea nitrogen (BUN), and smoking status consistently emerged as key features defining subtype structure and prognosis. Robust risk stratification was preserved even when clustering was restricted to these three routinely measured variables. Overall, our findings demonstrate that integrating outcome-driven feature attribution into clustering enables interpretable and clinically relevant CKD subtyping, providing a practical approach for characterizing disease heterogeneity and supporting risk stratification and personalized management. en-copyright= kn-copyright= en-aut-name=ShiTianyi en-aut-sei=Shi en-aut-mei=Tianyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YeXiucai en-aut-sei=Ye en-aut-mei=Xiucai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=XiWenyu en-aut-sei=Xi en-aut-mei=Wenyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImakuraAkira en-aut-sei=Imakura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaseKaori en-aut-sei=Mase en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsunodaRyoya en-aut-sei=Tsunoda en-aut-mei=Ryoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoChie en-aut-sei=Saito en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoAkihiko en-aut-sei=Kato en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=MaruyamaShoichi en-aut-sei=Maruyama en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WadaTakashi en-aut-sei=Wada en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 ORCID= en-aut-name=SakuraiTetsuya en-aut-sei=Sakurai en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Computer Science, University of Tsukuba kn-affil= affil-num=2 en-affil=Department of Computer Science, University of Tsukuba kn-affil= affil-num=3 en-affil=Department of Computer Science, University of Tsukuba kn-affil= affil-num=4 en-affil=Department of Computer Science, University of Tsukuba kn-affil= affil-num=5 en-affil=Department of Nephrology, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=6 en-affil=Department of Nephrology, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=7 en-affil=Department of Nephrology, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=8 en-affil=Blood Purification Unit, Hamamatsu University School of Medicine kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Nagoya University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Nephrology and Rheumatology, Kanazawa University kn-affil= affil-num=12 en-affil=Division of Clinical Nephrology and Rheumatology, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=13 en-affil=Department of Nephrology, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=14 en-affil=Department of Computer Science, University of Tsukuba kn-affil= en-keyword=Chronic kidney disease kn-keyword=Chronic kidney disease en-keyword=Outcome-aware clustering kn-keyword=Outcome-aware clustering en-keyword=Interpretable machine learning kn-keyword=Interpretable machine learning en-keyword=Risk stratification kn-keyword=Risk stratification en-keyword=Disease progression kn-keyword=Disease progression END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue= article-no= start-page=100152 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immersion is not enough: Design quality as the key determinant of perceived effectiveness and usage intention in educational virtual reality en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immersive technologies such as Virtual Reality (VR) are increasingly used to support conceptual understanding in science education, yet perceived learning benefits depend on the quality of system design rather than immersion alone. This study investigates how four design-quality dimensions?Visual and Technological Design (VT), Aesthetic Quality (AQ), Curriculum Alignment (CA), and Digital Feasibility (DF)?influence learners' Perceived Effectiveness (PE) and Intention to Use (IU) the VARIASI VR simulation, which visualizes particle behavior across phase states of matter. Using an explanatory sequential mixed-methods design, quantitative data from 60 participants were analyzed using PLS-SEM, followed by reflexive thematic analysis of open-ended responses. Results show that VT, AQ, CA, and DF each significantly predict PE, demonstrating that learners' perception of effectiveness depends on the coordinated alignment of conceptual clarity, emotional resonance, and system reliability. However, none of these dimensions directly predicted IU, and the PE ¨ IU relationship was positive but marginal, reflecting learnersf need for procedural guidance and comfort to sustain voluntary adoption. Qualitative findings reveal that while VR enhanced conceptual clarity and engagement, continued use depended on familiarity, scaffolding, and physical comfort. The study highlights that effective VR-based science learning experiences emerge when immersive environments are not only well-designed but pedagogically framed to support confidence and sustained use. en-copyright= kn-copyright= en-aut-name=SamsudinAchmad en-aut-sei=Samsudin en-aut-mei=Achmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZahranMuhammad en-aut-sei=Zahran en-aut-mei=Muhammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NugrahaEki en-aut-sei=Nugraha en-aut-mei=Eki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NasbeyHadi en-aut-sei=Nasbey en-aut-mei=Hadi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SozbilirMustafa en-aut-sei=Sozbilir en-aut-mei=Mustafa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RahmanNor Farahwahidah Abdul en-aut-sei=Rahman en-aut-mei=Nor Farahwahidah Abdul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IrieTakashi en-aut-sei=Irie en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Universitas Pendidikan Indonesia kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Universitas Pendidikan Indonesia kn-affil= affil-num=4 en-affil=Universitas Negeri Jakarta kn-affil= affil-num=5 en-affil=Atat?rk University kn-affil= affil-num=6 en-affil=Universiti Teknologi Malaysia kn-affil= affil-num=7 en-affil=Okayama University kn-affil= en-keyword=Virtual reality kn-keyword=Virtual reality en-keyword=Science education kn-keyword=Science education en-keyword=Immersive learning kn-keyword=Immersive learning en-keyword=Design quality kn-keyword=Design quality en-keyword=PLS-SEM kn-keyword=PLS-SEM en-keyword=Technology adoption kn-keyword=Technology adoption END start-ver=1.4 cd-journal=joma no-vol=542-543 cd-vols= no-issue= article-no= start-page=108716 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20261115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Serpentinization parageneses controlled by lithological variations among olivine gabbro and peridotite from the Atlantis Massif, Mid-Atlantic Ridge en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serpentinization of olivine impacts the geochemical and ecological environment via molecular hydrogen production, promoted by iron oxidation to form magnetite and ferric iron in serpentine. Previous studies suggested that serpentinization proceeds with various reactions and the extent of iron oxidation is variable depending on the reaction pathways. To examine the effect of lithological variation on reactions at an incipient stage of serpentinization, we carried out microscopic observations, electron-probe analyses, and Raman spectroscopy of serpentine veins cutting olivine in gabbroic rocks and peridotites from the Atlantis Massif, Mid-Atlantic Ridge. The results indicate that the serpentine veins in the proximity of olivine dominantly comprise lizardite mixed with variable minor phases or components depending on igneous lithology: brucite in peridotites, troctolites, and primitive olivine gabbros; cronstedtite-bearing serpentine, commonly without brucite, in some troctolites and slightly evolved olivine gabbros; and neither brucite nor cronstedtite component in evolved olivine gabbros. This suggests that incipient-stage serpentinization paragenesis is dominantly controlled by silica activity reflecting lithological variation. In addition to magnetite, the formation of cronstedtite in gabbroic rocks has the potential to produce hydrogen. The presence or absence of brucite and cronstedtite could affect the timing and magnitude of iron oxidation and hydrogen production during serpentinization. Considering the predominance of gabbroic rocks in the lower oceanic crust, the variation in incipient-stage serpentinization paragenesis in gabbroic rocks may have an impact on the redox state and ecological environment around the (sub)seafloor. en-copyright= kn-copyright= en-aut-name=NozakaToshio en-aut-sei=Nozaka en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KazumataShun en-aut-sei=Kazumata en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KleinFrieder en-aut-sei=Klein en-aut-mei=Frieder kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Marine Chemistry and Geochemistry, Woods Hole Oceanographic Institution kn-affil= en-keyword=Serpentinization kn-keyword=Serpentinization en-keyword=Brucite kn-keyword=Brucite en-keyword=Cronstedtite kn-keyword=Cronstedtite en-keyword=Olivine gabbro kn-keyword=Olivine gabbro en-keyword=Peridotite kn-keyword=Peridotite en-keyword=Atlantis Massif kn-keyword=Atlantis Massif END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=8 article-no= start-page=1884 end-page=1891 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Shoot-to-Root Ratio Serves as an Early Practical Indicator of Tipburn Risk in Lisianthus [Eustoma grandiflorum (Raf.) Shinn.] Seedlings en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tipburn is a calcium-related physiological disorder that reduces lisianthus seedling quality, yet the factors underlying cultivar differences remain unclear. This study evaluated 10 lisianthus cultivars to determine whether the shoot-to-root (S/R) ratio and key physiological traits influence tipburn susceptibility. Seedlings were grown in a closed production system with restricted root volume and once-daily irrigation to enhance symptom expression. The S/R ratio varied significantly among cultivars (2.82?4.02) and was strongly correlated with tipburn incidence (r = 0.744, P < 0.05) and severity (r = 0.706, P < 0.05). Cultivars with higher S/R ratios exhibited greater tipburn, whereas those with lower ratios showed little to no symptoms. Diurnal measurements of transpiration, stomatal conductance, leaf temperature, and electron transport rate revealed cultivar-specific physiological patterns; however, midday transpiration showed only a weak association with tipburn. These results indicate that biomass allocation, rather than physiological activity alone, is the primary factor governing tipburn susceptibility. The S/R ratio represents a simple and practical indicator for identifying high-risk cultivars in nursery production. Future studies should investigate the roles of calcium transport, developmental stage, and irrigation management in mitigating tipburn occurrence. en-copyright= kn-copyright= en-aut-name=SambaNethone en-aut-sei=Samba en-aut-mei=Nethone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkiKureha en-aut-sei=Iki en-aut-mei=Kureha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Hikawa-EndoMinori en-aut-sei=Hikawa-Endo en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamaYoko en-aut-sei=Miyama en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Food and Agricultural Sciences, Fukushima University kn-affil= affil-num=2 en-affil=Fukushima Prefectural Iwaki Agriculture and Forestry Office 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=Faculty of Food and Agricultural Sciences, Fukushima University, Fukushima, 960-1296, Japan; and The United Graduate School of Agricultural Sciences, Iwate University kn-affil= en-keyword=biomass allocation kn-keyword=biomass allocation en-keyword=calcium deficiency kn-keyword=calcium deficiency en-keyword=cultivar kn-keyword=cultivar en-keyword=physiology kn-keyword=physiology en-keyword=transpiration kn-keyword=transpiration END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=29 article-no= start-page=12214 end-page=12224 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Terpolymerization of epoxide, oxetane, and CO2 for the synthesis of polycarbonates with high CO2 contents, physical tunability, and enzymatic degradability en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although poly(cyclohexene carbonate) (PCHC) synthesized by the copolymerization of cyclohexene oxide (CHO) and CO2 is a promising material, the physical properties of this material need to be altered and tuned for its wider applications. To this end, we employed a terpolymerization strategy increasing the CO2 content in the resulting polymers. Terpolymerization of CHO, oxetane, and CO2 using AlIII porphyrin catalysts with quaternary ammonium halides afforded polycarbonates with high CO2 contents, physical tunability, and enzymatic degradability. The counter anions of the catalysts were crucial factors in the formation of the poly(trimethylene carbonate) (PTMC) unit. 1a with bromide ions preferentially produced trimethylene carbonate (TMC) over PTMC, while 1d with chloride ions suppressed the formation of TMC and produced PCHC?PTMC directly. PCHC?PTMC showed glass transition temperatures (Tg) between 69 ‹C and ?9 ‹C, depending on the PCHC/PTMC ratio. The tensile test revealed that the PTMC unit contributed to the softening of the film materials. For example, a film material with a CO2 content of 38 wt% showed 505% elongation at break with an elastic character, which contrasted starkly with the 1.3% elongation at break of PCHC with a CO2 content of 31 wt%. Moreover, the selective degradation of the PTMC unit in PCHC?PTMC was achieved with lipases, and a gradient character in the sequence structure was suggested. Overall, PCHC?PTMC is an environmentally benign and sustainable CO2-based polycarbonate. en-copyright= kn-copyright= en-aut-name=NikiKaito en-aut-sei=Niki en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=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=20260715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW-Scale and VSMOW?SLAP-Scale ƒ¢Œ17O Calibration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Triple oxygen isotope ratios of waters are commonly reported on the VSMOW?SLAP scale, whereas comparison with theoretical calculations and assessment of instrumental scale distortion require accurate constraints on the measured isotopic compositions of the primary isotopic reference materials (iRMs) themselves. In particular, the measured ƒÂ17OVSMOW and ƒ¢Œ17OVSMOW values for SLAP and its substitute, SLAP2, remain insufficiently constrained and reported values differ among laboratories. Here, we measured triple oxygen isotope ratios for two primary iRMs (VSMOW and SLAP) and twelve secondary iRMs (VSMOW2, SLAP2, GISP, GRESP, USGS45, USGS46, USGS46a, USGS47, USGS48, USGS49, USGS50 and USGS53) using BrF5 fluorination and dual-inlet isotope-ratio mass spectrometry. For SLAP, we obtained ƒÂ18OVSMOW = -55.50 }?0.15ñ and ƒÂ17OVSMOW = -29.66 }?0.08ñ, giving ƒ¢Œ17OVSMOW =?34 }?6 per meg (all expanded uncertainties, k =?2). The corresponding values for SLAP2 agree within uncertainty. When expressed on the conventional VSMOW?SLAP scale, our ƒ¢Œ17OVSMOW?SLAP values for all secondary iRMs with available literature values agree with previously published values within uncertainty, confirming interlaboratory comparability on that scale. In contrast, waters with low ƒÂ18O values, ƒ¢Œ17OVSMOW values are systematically higher than the corresponding ƒ¢Œ17OVSMOW?SLAP values. These results further suggest that accurate determination of the VSMOW-scale isotopic composition of SLAP and/or SLAP2 across laboratories is essential, particularly for low-ƒÂ18O samples, for which the difference between VSMOW-scale and VSMOW?SLAP-scale ƒ¢Œ17O values becomes large, and for meaningful comparison between measured data and theoretical calculations. en-copyright= kn-copyright= en-aut-name=TanakaRyoji en-aut-sei=Tanaka en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PackAndreas en-aut-sei=Pack en-aut-mei=Andreas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CoplenTyler B. en-aut-sei=Coplen en-aut-mei=Tyler B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Georg-August-Universit?t G?ttingen, Geowissenschaftliches Zentrum kn-affil= affil-num=3 en-affil=US Geological Survey kn-affil= en-keyword=primary isotopic reference material kn-keyword=primary isotopic reference material en-keyword=secondary isotopic reference material kn-keyword=secondary isotopic reference material en-keyword=triple oxygen isotopes kn-keyword=triple oxygen isotopes en-keyword=VSMOW-SLAP scale kn-keyword=VSMOW-SLAP scale 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=20260722 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dissociation between globe shape-induced rectus muscle pulley displacement and abduction limitation in patients aged 40?years and older with high myopic strabismus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose We hypothesized that high myopia (HM)-induced globe deformation displaces rectus muscle (RM) pulleys, contributing to mild ocular motility restriction. This study investigated the effects of globe shape on RM pulley positions in older Japanese patients with acquired strabismus (AS) and mild motility restriction?defined as the ability to abduct both eyes beyond the midline.
Methods In this retrospective case series, 28 patients (mean age?}?standard deviation: 61.2?}?9.0 years) with adult-onset AS were included: 6 patients with (LAB group) and 22 patients without abduction limitation (NLAB group). In each subject, the eye with the longer axial length (AL???26 mm), measured using an AL measurement apparatus, was analyzed using magnetic resonance imaging (MRI). RM pulley positions relative to the globe center and equatorial diameter (ED) were measured; the ED-to-AL ratio (EAR) was calculated. We compared these parameters between groups and analyzed correlations of globe-shape factors (EAR, AL, and ED) with pulley positions and age.
Results No significant differences in EAR, AL, ED, or pulley positions were detected between LAB and NLAB groups, possibly owing to the limited sample size and group imbalance, in the analyzed eyes. However, as EAR decreased (prolate deformation), the superior rectus (SR) pulley (r?=?0.68, P? Conclusions In older Japanese patients with HM and AS, prolate globe deformation was associated with age and significantly correlated with SR and IR pulley positions. While the direct relationship between these structural changes and the clinical degree of mild abduction limitation requires further investigation in larger cohorts, EAR sensitively reflected age-related morphological shifts; thus, when used in conjunction with AL, EAR may represent a readily measurable MRI-based parameter associated with restrictive motility tendencies in strabismus with high myopia. en-copyright= kn-copyright= en-aut-name=KonoReika en-aut-sei=Kono en-aut-mei=Reika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KishimotoFumiko en-aut-sei=Kishimoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShibataKiyo en-aut-sei=Shibata en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorisawaShin en-aut-sei=Morisawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Lino Eye Clinic kn-affil= affil-num=3 en-affil=Division of Ophthalmology, Ibara City Hospital kn-affil= affil-num=4 en-affil=Lino Eye Clinic kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Heavy eye syndrome kn-keyword=Heavy eye syndrome en-keyword=High myopia kn-keyword=High myopia en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Prolate deformation kn-keyword=Prolate deformation en-keyword=Rectus muscle pulley kn-keyword=Rectus muscle pulley en-keyword=Strabismus kn-keyword=Strabismus 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=Studentsf 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 studentsf 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, studentsf 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 studentsf questions and respond during class, providing a practical approach to in-class feedback. en-copyright= kn-copyright= en-aut-name=KomatsuY. en-aut-sei=Komatsu en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbeS. en-aut-sei=Abe en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsudouS. en-aut-sei=Tsudou en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoY. en-aut-sei=Yamamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeY. en-aut-sei=Tanabe en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Care Sciences, Jikei University of Health Care Sciences kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Health Sciences, Department of Radiological Technology, Okayama University Medical School, Okayama University kn-affil= en-keyword=Electronic 1-min paper kn-keyword=Electronic 1-min paper en-keyword=Formative assessment kn-keyword=Formative assessment en-keyword=Radiography education kn-keyword=Radiography education en-keyword=Immediate feedback kn-keyword=Immediate feedback en-keyword=Student engagement kn-keyword=Student engagement en-keyword=Health professions education kn-keyword=Health professions education END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=7 article-no= start-page=455 end-page=460 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dielectric response modulation in relaxor (Sr,Ba)Nb2O6 via engineered defect en-subtitle= kn-subtitle= en-abstract= kn-abstract=Defect engineering provides an effective pathway to tune the dielectric response of relaxor ferroelectrics, yet the roles of individual defect species in tungsten bronze (TTB) systems remain unclear. Here, we investigated how engineered Ti?VO?? defect dipoles and native oxygen vacancies introduced through reduction annealing modify the dielectric properties of relaxor (Sr0.5,Ba0.5)Nb2O6 (0.5-SBN). Ti loading forms stable defect dipoles that generate smaller polar nanoregions (PNRs), suppress their overgrowth, and increase the number of dynamically active PNRs at room temperature, leading to enhanced permittivity ƒÃŒ while preserving DC-bias stability and breakdown strength (EB). Reduction annealing generates Nb4+-related local polarizations aligned with the external electric field, which strengthen dipole fluctuations and slightly increase ƒÃŒ. Electron localization further relaxes the TTB-A2 site disorder?induced random fields, yielding a sharper dielectric peak and promoting more uniform PNR growth. Microwave dielectric spectroscopy combined with electromagnetic simulations revealed that the increases in ƒÃŒ for both Ti-loaded and reduced samples (0.5-SBNT and Reduced 0.5-SBN, respectively) originate predominantly from enhanced dipole polarization. Despite grain coarsening in 0.5-SBNT, the EB remained unchanged, indicating that defect dipoles act as pinning centers that inhibit field-induced PNR aggregation. In reduced 0.5-SBN, EB increased up to pO0 = 4.3 ~ 10?3 atm owing to relaxed random fields, whereas excessive reduction reduced EB through carrier-driven space-charge effects. These results demonstrate that precise control of defect species enables simultaneous optimization of ƒÃŒ, DC-bias stability, and EB in TTB-type relaxor ferroelectrics. en-copyright= kn-copyright= en-aut-name=ShiotaRyusei en-aut-sei=Shiota en-aut-mei=Ryusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoShinya en-aut-sei=Kondo en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Energy Engineering, Nagoya University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Relaxor ferroelectrics kn-keyword=Relaxor ferroelectrics en-keyword=(Sr,Ba)Nb2O6 kn-keyword=(Sr,Ba)Nb2O6 en-keyword=Polar nanoregions kn-keyword=Polar nanoregions en-keyword=Dipole polarization kn-keyword=Dipole polarization en-keyword=DC bias response kn-keyword=DC bias response END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=2 article-no= start-page=228 end-page=236 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=A Case of Acquired LCAT Deficiency with the Discrepancy between Spontaneous Resolution of Proteinuria and Continually Low HDL Cholesterol Levels en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 79-year-old Chinese man was referred for nephrotic syndrome (proteinuria 4.4 g/day). In blood tests, serum high-density lipoprotein (HDL) cholesterol was undetectable, and the esterified cholesterol to total cholesterol ratio was very low. Lecithin: cholesterol acyltransferase (LCAT) activity was also undetectable. Since he had neither corneal opacity nor pathological mutations in the LCAT gene and anti-LCAT antibodies were detected in serum, a diagnosis of acquired LCAT deficiency was made. Renal biopsy revealed glomerulopathy associated with LCAT deficiency and membranous nephropathy (MN). Since the patientfs proteinuria did not improve despite prescribing an angiotensin II receptor blocker (ARB), we suggested the prescription of prednisolone, but he returned to China due to the expiration of his residence visa for Japan. One year after the initial visit, his proteinuria had improved to 0.9 g/day without immunosuppressive therapy. However, his HDL cholesterol level was still low at around 3 mg/dL, indicating a discrepancy between remission of nephrotic syndrome and lack of improvement in lipid levels.
Of the 11 patients with acquired LCAT deficiency reported to date, 4 with undetectable LCAT activity and MN on renal biopsy required immunosuppressive therapy to alleviate proteinuria. The present patient was prescribed only an ARB according to his preference, which happened to be consistent with the MN treatment guideline that states, gWait 6 months for spontaneous remission while using maximal antiproteinuric therapy.h The clinical course of acquired LCAT deficiency varies, and further case reports are needed to determine the necessity of immunosuppressive therapy. en-copyright= kn-copyright= en-aut-name=MatsuoMiki en-aut-sei=Matsuo en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OguraMasatsune en-aut-sei=Ogura en-aut-mei=Masatsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaMasayuki en-aut-sei=Kuroda en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArisatoTetsuya en-aut-sei=Arisato en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KishidaMasatsugu en-aut-sei=Kishida en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Harada-ShibaMariko en-aut-sei=Harada-Shiba en-aut-mei=Mariko 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= en-aut-name=YokoteKoutaro en-aut-sei=Yokote en-aut-mei=Koutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshiharaFumiki en-aut-sei=Yoshihara en-aut-mei=Fumiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Nephrology and Hypertension, National Cerebral and Cardiovascular Center kn-affil= affil-num=2 en-affil=Department of Clinical Laboratory Technology, Faculty of Medical Science, Juntendo University kn-affil= affil-num=3 en-affil=Center for Advanced Medicine, Chiba University Hospital, Chiba University kn-affil= affil-num=4 en-affil=Department of Nephrology and Hypertension, National Cerebral and Cardiovascular Center kn-affil= affil-num=5 en-affil=Department of Nephrology and Hypertension, National Cerebral and Cardiovascular Center kn-affil= affil-num=6 en-affil=Cardiovascular Center, Osaka Medical and Pharmaceutical University kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Endocrinology, Hematology and Gerontology, Chiba University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Nephrology and Hypertension, National Cerebral and Cardiovascular Center kn-affil= en-keyword=Acquired LCAT deficiency kn-keyword=Acquired LCAT deficiency en-keyword=HDL deficiency kn-keyword=HDL deficiency en-keyword=Nephrotic syndrome kn-keyword=Nephrotic syndrome en-keyword=Membranous glomerulonephritis kn-keyword=Membranous glomerulonephritis 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 weeksf 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=Parkinsonfs disease kn-keyword=Parkinsonfs 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=53 cd-vols= no-issue=14 article-no= start-page=e2026GL121981 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Calcium Solubility of Bridgmanite in Subducted Basalt in Earth's Lower Mantle en-subtitle= kn-subtitle= en-abstract= kn-abstract=The calcium solubility in bridgmanite and the resulting abundance of davemaoite under lower-mantle pressure-temperature conditions have been under debate following a recent report of extensive calcium dissolution in bridgmanite. We experimentally investigated the calcium solubility in bridgmanite in a basaltic composition at pressures up to 125 GPa and temperatures up to 3,520 K. Our experimental data are modeled thermodynamically along the bridgmanite-davemaoite solvus to quantify the calcium solubility in bridgmanite and the davemaoite proportion in basaltic and pyrolitic assemblages along lower mantle geotherms. Our results indicate that bridgmanite hosts only 0.001?0.03 Ca cations per formula unit in the lower mantle, while davemaoite remains as an abundant mineral, accounting for 8 and 25 vol% of pyrolitic and basaltic mineralogical models, respectively, along representative lower-mantle geotherms. Our thermoelastic modeling further indicates that the effect of calcium dissolution on the density and bulk sound velocity of lower-mantle assemblages is negligible. en-copyright= kn-copyright= en-aut-name=ZhangChengwei en-aut-sei=Zhang en-aut-mei=Chengwei 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=El GhazaouiElias en-aut-sei=El Ghazaoui en-aut-mei=Elias kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CharitonStella en-aut-sei=Chariton en-aut-mei=Stella kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PrakapenkaVitali B. en-aut-sei=Prakapenka en-aut-mei=Vitali B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LiLuo en-aut-sei=Li en-aut-mei=Luo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhangYanyao en-aut-sei=Zhang en-aut-mei=Yanyao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LinJung]Fu en-aut-sei=Lin en-aut-mei=Jung]Fu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences The University of Texas at Austin kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=School of Earth and Environmental Sciences, Seoul National University kn-affil= affil-num=4 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=5 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=6 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences The University of Texas at Austin kn-affil= affil-num=7 en-affil=Earth and Planetary Sciences, Stanford University kn-affil= affil-num=8 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences The University of Texas at Austin kn-affil= END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=1 article-no= start-page=21 end-page=32 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=The Current State and Challenges of the Academic Economics Job Market in China: An Analysis of Incentive Structures Based on Crowdsourced Data kn-title=’†‘‚É‚¨‚¯‚éŒoÏŠwƒAƒJƒfƒ~ƒbƒNEƒWƒ‡ƒuƒ}[ƒPƒbƒg‚ÌŒ»ó‚Ɖۑè \ƒNƒ‰ƒEƒhƒ\[ƒVƒ“ƒOEƒf[ƒ^‚ÉŠî‚­ƒCƒ“ƒZƒ“ƒeƒBƒu\‘¢‚Ì•ªÍ\ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WangRuiting en-aut-sei=Wang en-aut-mei=Ruiting kn-aut-name=‰¤áÍè» kn-aut-sei=‰¤ kn-aut-mei=áÍè» aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=‰ªŽR‘åŠwŒoÏŠw•” END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=8 article-no= start-page=1172 end-page=1177 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Autopsy Case of a Disseminated Cytomegalovirus Infection with a Cutaneous Ulcer Mimicking Rheumatoid Vasculitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 60-year-old woman with rheumatoid arthritis and an impaired consciousness was referred to our hospital. Prior to transfer, the patient underwent intensified immunosuppressive therapy under a diagnosis of rheumatoid vasculitis that had developed in her buttocks. Upon hospitalization, she developed severe multiorgan failure and hemophagocytic syndrome. Four days after admission, both blood cytomegalovirus (CMV) antigenemia and the DNA load were markedly elevated. Despite intensive care, the patient died. Later, a histopathological examination revealed that the cutaneous manifestation represented CMV disease, not rheumatoid vasculitis, as was initially suspected. Failure to identify CMV as the underlying cause may result in the inappropriate administration of immunosuppressive therapy, potentially worsening the patient's condition. en-copyright= kn-copyright= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoYukichika en-aut-sei=Yamamoto en-aut-mei=Yukichika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaTomoharu en-aut-sei=Ishida en-aut-mei=Tomoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhkiTomoka en-aut-sei=Ohki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=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=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 General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=autopsy kn-keyword=autopsy en-keyword=cytomegalovirus kn-keyword=cytomegalovirus en-keyword=cutaneous cytomegalovirus kn-keyword=cutaneous cytomegalovirus en-keyword=virus-associated hemophagocytic syndrome kn-keyword=virus-associated hemophagocytic syndrome en-keyword=rheumatoid vasculitis kn-keyword=rheumatoid vasculitis END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=3 article-no= start-page=107 end-page=115 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Full-endoscopic Laminotomy Is Effective for Lumbar Spinal Stenosis with Low-grade Spondylolisthesis: A Comparative Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The optimal management of lumbar spinal canal stenosis with spondylolisthesremains controversial, particularly when choosing between decompression alone or decompression with fusion. Current evidence is based on conventional open or endoscopy-assisted surgeries, with limited data on full-endoscopic decompression. This study aimed to assess the impact of spondylolisthesis on outcomes after full-endoscopic laminotomy by evaluating back pain-related disability scores in patients with lumbar spinal canal stenosis, with and without spondylolisthesis. A retrospective analysis was conducted at Iwai Orthopaedic Hospital, Japan. Patients with lumbar spinal canal stenosis who underwent full-endoscopic laminotomy between January 2021 and December 2022 were included and categorized into those without spondylolisthesis and those with spondylolisthesis. Postoperative Oswestry Disability Index scores at 2 years were compared in the groups using multivariable linear regression, adjusting for confounding factors. Exploratory analyses were also conducted to identify factors affecting the Oswestry Disability Index in the patients with lumbar spinal canal stenosis with spondylolisthesis group. Statistical significance was set at p < 0.05. The study included 80 patients, with 40 in each group. Both groups showed improved postoperative Oswestry Disability Index. There was no significant association between spondylolisthesis and postoperative Oswestry Disability Index. However, cauda equina redundancy negatively affected postoperative Oswestry Disability Index improvement in the patients with lumbar spinal canal stenosis with spondylolisthesis group. Full-endoscopic laminotomy is an effective surgical option for lumbar spinal canal stenosis, leading to significant alleviation of disability and improvements in quality of life, regardless of spondylolisthesis. Full-endoscopic laminotomy may offer similar functional improvements regardless of the presence of low-grade spondylolisthesis, supporting its role as a less invasive alternative to fusion. en-copyright= kn-copyright= en-aut-name=KINKyohei en-aut-sei=KIN en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TOMINAGARyoji en-aut-sei=TOMINAGA en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TAKEBAYASHIKento en-aut-sei=TAKEBAYASHI en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IWAIHiroki en-aut-sei=IWAI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=INANAMIHirohiko en-aut-sei=INANAMI en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KOGAHisashi en-aut-sei=KOGA en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedics, Iwai Orthopaedic Medical Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedics, Iwai Orthopaedic Medical Hospital kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedics, Iwai Orthopaedic Medical Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedics, Iwai Orthopaedic Medical Hospital kn-affil= en-keyword=full-endoscopic spine surgery kn-keyword=full-endoscopic spine surgery en-keyword=spondylolisthesis kn-keyword=spondylolisthesis en-keyword=full-endoscopic laminotomy kn-keyword=full-endoscopic laminotomy en-keyword=minimally invasive kn-keyword=minimally invasive en-keyword=lumbar spinal canal stenosis kn-keyword=lumbar spinal canal stenosis END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=11 article-no= start-page=1520 end-page=1523 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endotracheal and Endobronchial Metastases in Epidermal Growth Factor Receptor Exon 19 Deletion Lung Adenocarcinoma: A Case Successfully Managed with Bronchoscopic Therapy and Sequential Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endotracheal and endobronchial metastases from peripheral lung adenocarcinoma are rare, and optimal clinical management remains unclear. We herein report a 60-year-old woman with epidermal growth factor receptor (EGFR) exon 19 deletion-positive early-stage lung adenocarcinoma who underwent surgical resection followed by osimertinib treatment for recurrence. She later developed oligoprogressive disease with airway metastases. Bronchoscopic tumor removal was performed, and next-generation sequencing of the resected specimen revealed an acquired EGFR C797S mutation, along with exon 19 deletion. Gefitinib treatment was initiated, which led to a partial response. This case underscores the utility of repeated molecular profiling and local intervention in managing acquired resistance in EGFR-mutant non-small-cell lung cancer. en-copyright= kn-copyright=

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.

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), patientsf self-assessed understanding exceeded the dental stafffs 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, patientsf 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=26 cd-vols= no-issue=1 article-no= start-page=628 end-page= 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=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=131 cd-vols= no-issue=7 article-no= start-page=e2025JE009578 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=Surface Geology and Evolution of Asteroid Ryugu: Insights From Hayabusa2 Global Mapping en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rubble-pile asteroids, characterized by loose aggregates of debris held together by gravity, represent both a significant planetary hazard and a key to understanding planetesimal formation. Geologic mapping of these bodies provides essential insights into their origins, evolution, and surface processes. This knowledge is crucial for advancing space mission capabilities, from precise navigation and safe sampling to assessing the feasibility of future asteroid mining. Here, we present the most comprehensive geologic map of Ryugu in comparison to previous early-stage and single-feature maps, integrating Optical Navigation Camera (ONC) mosaics, LIDAR-derived topography, Mobile Asteroid Surface Scout (MASCOT) descent images, and spectral slope data. The analysis includes reclassification of previously identified features and newly identified features from global to local scales. The geologic mapping technique followed United States Geological Survey (USGS) planetary cartography standards using the ArcGIS Pro platform. This global framework provides an essential geologic context for interpreting returned samples and constraining rubble-pile evolution. We identified geomorphological, structural, and surface texture units on Ryugu's unconsolidated rubble-pile surface using 0.2?0.7 m/pixel image mosaics. Elongated troughs at the poles and mirrored, oblique lineaments near the equatorial ridge are consistent with rotational strain. Compared with another rubble-pile asteroid Bennu, Ryugu shows a more uniform boulder distribution, and its immensely prominent equatorial ridge indicates a more intense period of rotational deformation. However, the western bulge deviates from this trend; its fewer boulders, underdeveloped ridges, and older degraded craters suggest selective resurfacing. These features show evidence of catastrophic disruption, rotational reshaping, and ongoing surface movement. en-copyright= kn-copyright= en-aut-name=VincentLisa M. en-aut-sei=Vincent en-aut-mei=Lisa M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=RayAditya en-aut-sei=Ray en-aut-mei=Aditya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikuchiHiroshi en-aut-sei=Kikuchi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HemmiRyodo en-aut-sei=Hemmi en-aut-mei=Ryodo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyamotoHideaki en-aut-sei=Miyamoto en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugitaSeiji en-aut-sei=Sugita en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=the Hayabusa2 ONC science team en-aut-sei=the Hayabusa2 ONC science team en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Utrecht University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=International Research School of Planetary Sciences, Universit?

These complexes are air-stable and extremely effective precatalysts in the Suzuki-Miyaura cross-coupling reaction. The reaction protocols described allow for the cross-coupling of aryl chlorides and arylboronic acids, employing low catalytic loading, to deliver a large variety of functionalized biaryl compounds. For the coupling of aryl chlorides with N-heterocyclic boronic acids, TBAF was used as an additive to afford nitrogen-containing biaryl products. Overall, these reaction protocols operate at room or mild temperatures and can be applied to a variety of electronically and sterically differentiated coupling partners. Fundamental insights into the mechanism of this reaction, including the proposed formation of the catalytically active Ni(NHC)[P(Oi-Pr)3] and resting state species, are also reported. en-copyright= kn-copyright= en-aut-name=JohnMorgan E. en-aut-sei=John en-aut-mei=Morgan E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NuttMichael J. en-aut-sei=Nutt en-aut-mei=Michael J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OfferJosephine E. en-aut-sei=Offer en-aut-mei=Josephine E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DuczynskiJeremy A. en-aut-sei=Duczynski en-aut-mei=Jeremy A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiuraTomoya en-aut-sei=Miura en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoggachStephen A. en-aut-sei=Moggach en-aut-mei=Stephen A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoutsantonisGeorge A. en-aut-sei=Koutsantonis en-aut-mei=George A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DortaReto en-aut-sei=Dorta en-aut-mei=Reto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=StewartScott G. en-aut-sei=Stewart en-aut-mei=Scott G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=2 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=3 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=4 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=6 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=7 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=8 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=9 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= affil-num=10 en-affil=School of Molecular Sciences, The University of Western Australia (M310) kn-affil= en-keyword=Air Stable kn-keyword=Air Stable en-keyword=Aryl Chlorides kn-keyword=Aryl Chlorides en-keyword=Boronic Acids kn-keyword=Boronic Acids en-keyword=Nickel Catalysis kn-keyword=Nickel Catalysis en-keyword=Room Temperature kn-keyword=Room Temperature en-keyword=Suzuki-Miyaura Cross-Coupling kn-keyword=Suzuki-Miyaura Cross-Coupling 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-ƒ¿?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=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=47 cd-vols= no-issue=12 article-no= start-page=2058 end-page=2064 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Staphylococcus aureus ƒÂ-Toxin Induces Ca2+ Influx-Independent Degranulation of Murine Cultured Mast Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cutaneous colonization with Staphylococcus aureus (SA) is frequently observed in patients with atopic dermatitis. SA produces a wide variety of bacterial toxins, among which ƒÂ-toxin was found to induce degranulation of mast cells. Degranulation of mast cells could enhance bacterial clearance and protection from future SA infection but lead to exacerbation of atopic dermatitis. Because it remains to be determined how ƒÂ-toxin triggers degranulation, we investigated ƒÂ-toxin-induced changes in murine bone marrow-derived cultured mast cells in this study. We found that ƒÂ-toxin-induced degranulation could be classified into two phases, an early Ca2+-independent and a late Ca2+-dependent phase. Recent studies suggest that NOD-like receptor family, pyrin domain containing 3 is involved in the degranulation of mast cells, raising a possibility that leakage of K+ induced by ƒÂ-toxin is involved in the Ca2+-independent phase. However, Ca2+-independent degranulation remains unchanged although Ca2+-influx and degranulation induced by ƒÂ-toxin were significantly suppressed in the presence of high concentrations of K+. Because actin depolymerization was reported to induce degranulation in the absence of Ca2+ in the permeabilized rat peritoneal mast cells, a slow but steady decrease in the amount of filamentous actin observed here may be involved in Ca2+-independent degranulation induced by ƒÂ-toxin. Although Mas-related G protein-coupled receptor (MRGPR) X2 in humans and Mrgprb2 in mice are regarded as the receptors responsible for immunoglobulin E-independent degranulation, ƒÂ-toxin-induced degranulation remained unchanged in Mrgprb2?/? mast cells. Our findings pave the way for identification of the target receptors of ƒÂ-toxin. en-copyright= kn-copyright= en-aut-name=LiuKang en-aut-sei=Liu en-aut-mei=Kang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatayamaTomoaki en-aut-sei=Katayama en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoHitomi en-aut-sei=Sato en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Hamaoka-TamuraYuho en-aut-sei=Hamaoka-Tamura en-aut-mei=Yuho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoMichiko en-aut-sei=Saito en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Laboratory of Pharmacology, Division of Pathological Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=2 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Laboratory of Pharmacology, Division of Pathological Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=5 en-affil=Bioscience Research Center, Kyoto Pharmaceutical University kn-affil= affil-num=6 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Laboratory of Pharmacology, Division of Pathological Sciences, Kyoto Pharmaceutical University kn-affil= en-keyword=mast cell kn-keyword=mast cell en-keyword=ƒÂ-toxin kn-keyword=ƒÂ-toxin en-keyword=degranulation kn-keyword=degranulation en-keyword=inflammation kn-keyword=inflammation en-keyword=Mas-related G protein-coupled receptor kn-keyword=Mas-related G protein-coupled receptor END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue=5 article-no= start-page=055009 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analytical study of birefringent cavities for axionlike dark matter search en-subtitle= kn-subtitle= en-abstract= kn-abstract=Light polarization plays a crucial role in optical-cavity experiments; however, mirror birefringence presents a significant challenge that must be addressed carefully. In this study, a rigorous, nonperturbative framework is developed to quantify birefringence effects by incorporating variations in reflectance and polarization misalignment. We analyze the impact of this framework on the sensitivity of axionlike particle (ALP) dark matter searches. The results show that both birefringence and misalignment contribute to sensitivity degradation in the low-mass regime; however, the adverse effects of misalignment can be mitigated by selecting a postselection angle greater than the misalignment angle. Furthermore, birefringence produces an additional resonance peak in the high-mass region, which remains largely unaffected by misalignment and postselection variations. This rigorous framework underscores the importance of considering birefringence in high-precision optical-cavity experiments for ALP detection. en-copyright= kn-copyright= en-aut-name=KuramotoTadashi en-aut-sei=Kuramoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImaiYasutaka en-aut-sei=Imai en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasudaTakahiko en-aut-sei=Masuda en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShikanoYutaka en-aut-sei=Shikano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakatoriSayuri en-aut-sei=Takatori en-aut-mei=Sayuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UetakeSatoshi en-aut-sei=Uetake en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=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=Institute of Systems and Information Engineering, University of Tsukuba kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= 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=40 cd-vols= no-issue=52 article-no= start-page=27314 end-page=27322 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formation of Nonspherical Cellulose Acetate Microparticles under Microflow en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nonspherical particles have gained significant interest owing to their unique shapes and large specific surface areas, making them suitable for a wide range of applications, such as drug delivery, catalysis, and adsorption. However, conventional methods for preparing nonspherical particles face certain limitations. In this study, we propose a simple method for fabricating nonspherical cellulose acetate (CA) microparticles using a microfluidic device in which droplets undergo rapid diffusion in a continuous aqueous phase. The influence of variations in the flow rate ratio and continuous phase composition on the dimensionless P?clet number (Pe) within the droplet and shape of the resultant particles is investigated. Pe is critical, because it indicates the balance between polymer diffusion and droplet shrinkage dynamics. Our findings reveal that increasing the flow rate ratio and reducing the methyl acetate concentration in the continuous phase lead to faster droplet shrinkage and an increased Pe. A high Pe (>100) suggests that the reduction of the droplet interface predominates over polymer diffusion, resulting in the formation of a viscous layer near the droplet surface, which subsequently leads to nonspherical particle shapes (such as bowl-like or biconcave structures). In situ time-lapse observations of droplets from the top and side of a microchannel reveal that the formation of a viscous layer near the droplet surface and the deformation of the droplet, influenced by the z-axis location of the droplets during particle formation, ultimately determine the final particle shape. Based on these observations, a linear correlation between the initial conditions, i.e., the Pe and z-axis location at which the viscous layer formed, is established, enabling the prediction of the particle structure. In summary, the present study enhances the understanding of shape control in microfluidic particle formation and offers a novel guideline for the fabrication of spherical and nonspherical particles. en-copyright= kn-copyright= en-aut-name=MoriKurumi en-aut-sei=Mori en-aut-mei=Kurumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=11 article-no= start-page=8052 end-page=8058 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=Enhanced capacity of aluminum-ion batteries by adjusting the average pore size of the porous carbon cathode en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lithium-ion batteries (LIBs) are widely used but with the increasing scarcity and uneven distribution of global lithium resources, there is a need to explore alternative battery technologies. Due to its abundance, low cost, and high theoretical capacity, aluminum is a strong candidate for metal anodes, making aluminum-ion batteries (AIBs) an area of considerable interest. Current mainstream research focuses on ionic liquid electrolytes, which offer a wide electrochemical window and high ionic conductivity. Carbon materials are ideal cathode candidates due to their low cost, abundance, and high voltage platform. AIBs using carbon materials typically exhibit low discharge capacity. This study addressed the challenge of improving the discharge capacity of carbon-based cathodes in AIBs. By using porous carbon (PC) materials with varying specific surface areas, average pore sizes, and total pore volumes as cathodes, average pore size was found to impact capacity. This contradicts the contention that larger specific surface areas result in higher capacities. There is a key difference in ion behavior: whereas aluminum chloride ions intercalate into layered graphite structures, they do not intercalate into PC materials but are adsorbed to the surface. By adjusting the average pore size, it is possible to increase the discharge capacity of AIBs, challenging the traditional emphasis on specific surface area. This research does not fully solve the problem of low discharge capacity in carbon-based cathodes, but provides a new perspective on the role of pore size in enhancing battery performance, offering valuable insights for future electrode design. en-copyright= kn-copyright= en-aut-name=ChenYifeng en-aut-sei=Chen en-aut-mei=Yifeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroo en-aut-sei=Suzuki en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukumotoShu en-aut-sei=Fukumoto en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishikawaTakeshi en-aut-sei=Nishikawa en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UmezawaShigeyuki en-aut-sei=Umezawa en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayashiYasuhiko en-aut-sei=Hayashi en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= 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=Department of Comprehensive Technical Solutions, 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=Seiwa Electric Mfg.

Methods: We conducted a longitudinal cohort study of all children born in Japan during 2?weeks in January and July 2001. We defined outdoor play habits at age 2.5?years (third survey) as exposure, while parent-reported height and weight at age 7?years (seventh survey) were defined as overweight and obesity status using the WHO reference. Logistic regression models were used to estimate odds ratios (ORs) for associations between preschool outdoor play habits and school-age obesity, adjusting for parental and child factors.
Results: Of 53?575 children born, 42?812 had data on outdoor play habits at age 2.5?years, with 91% (38?970) having such habits. At age 7?years, 31?743/42?812 (74%) children had height and weight data, with 3249/31?743 (10%) classified as overweight or obesity (BMI SD score??1.0). Outdoor play habits were negatively associated with obesity (adjusted OR 0.85, 95% confidence interval (CI): 0.74?0.97).
Conclusion: Outdoor play habits in early preschool years are associated with a reduced risk of school-age obesity. Parents and caregivers may consider encouraging their children to outdoor play habits at an early age to help prevent obesity later in life. en-copyright= kn-copyright= en-aut-name=TsugeTakahiro en-aut-sei=Tsuge en-aut-mei=Takahiro 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=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=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=outdoor play habits kn-keyword=outdoor play habits en-keyword=physical activity kn-keyword=physical activity en-keyword=preschool kn-keyword=preschool en-keyword=school-aged obesity kn-keyword=school-aged obesity en-keyword=socioeconomic status kn-keyword=socioeconomic status END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=11 article-no= start-page=e202420949 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stereoselective Preparation and Palladium-Catalyzed Suzuki?Miyaura Cross-Coupling of Alkenyl Sulfoximines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although numerous transition-metal catalyzed cross-coupling reactions of alkenyl electrophiles with a sulfur(VI) leaving group, mainly alkenyl sulfones, have been developed, most rely heavily on highly nucleophilic Grignard reagents, and the use of organoboron reagents remains challenging. We report herein facile preparation and the following Pd-catalyzed Suzuki?Miyaura cross-coupling reaction of alkenyl sulfoximine, a monoaza analog of sulfone. The condensation of alkyl sulfoximine with aldehydes, developed in this study, makes alkenyl sulfoximines more readily available. The resulting alkenes undergo an unprecedented oxidative addition of the C?S bond to the Pd center. This cross-coupling proceeds with retention of its original stereochemistry and provided alkenes bearing three different functionalities in a stereoselective fashion. DFT calculations highlight the critical role of boronic acid and in situ-generated boroxines in facilitating this transformation. en-copyright= kn-copyright= en-aut-name=YasuiKosuke en-aut-sei=Yasui en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomishimaYuichiro en-aut-sei=Tomishima en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiuraTomoya en-aut-sei=Miura en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiranoKoji en-aut-sei=Hirano en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Applied Chemistry Graduate School of Engineering, Osaka University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry Graduate School of Engineering, Osaka University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry Graduate School of Engineering, Osaka University kn-affil= en-keyword=Sulfoximines kn-keyword=Sulfoximines en-keyword=Condensation kn-keyword=Condensation en-keyword=Cross-coupling kn-keyword=Cross-coupling en-keyword=Trisubstituted alkenes kn-keyword=Trisubstituted alkenes en-keyword=Stereoselectivity kn-keyword=Stereoselectivity 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=392 cd-vols= no-issue=1 article-no= start-page=1051 end-page=1097 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=Global well-posedness and scattering 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=40 cd-vols= no-issue=4 article-no= start-page=561 end-page=568 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Central dentinogenic ghost cell tumor of the maxilla: a case report with new imaging findings and review of the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=A dentinogenic ghost cell tumor (DGCT) is a rare benign odontogenic tumor that commonly shows characteristics of solid proliferation and has a relatively high risk of recurrence after surgical treatment. We herein report a case of a central DGCT that occurred in the maxilla and resulted in bone expansion. This study highlights new imaging findings (particularly magnetic resonance imaging) along with histopathological observations. In addition, we conducted a review of the existing literature on this rare tumor. A 37-year-old man developed swelling around the right cheek. A benign odontogenic tumor such as ameloblastoma was suspected based on the imaging examination findings (including bone expansion and the internal characteristics of the tumor) on panoramic imaging, computed tomography, and magnetic resonance imaging. The lesion was surgically excised from the right maxilla. Postoperative histopathological examination led to a definitive diagnosis of central DGCT. The tumor comprised epithelial neoplastic islands, resembling ameloblastoma, inside tight fibroconnective tissue; masses of ghost cells and formation of dentin were also observed. We had suspected that the minute high-density region around the molars on the imaging examinations represented alveolar bone change; however, it represented dentin formation. This led to difficulty diagnosing the lesion. Although DGCT may present characteristic findings on imaging examinations, its occurrence is infrequent, and in some cases, the findings may include the presence or absence of an impacted tooth without obvious calcification. The present case suggests that we should consider the possibility of an odontogenic tumor with calcification when high-density structures are observed inside the lesion. en-copyright= kn-copyright=

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=

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=134 cd-vols= no-issue=24 article-no= start-page=245001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acceleration of Positive Muons by a Radio-Frequency Cavity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acceleration of positive muons from thermal energy to 100 keV has been demonstrated. Thermal muons were generated by resonant multiphoton ionization of muonium atoms emitted from a sheet of laser-ablated aerogel. The thermal muons were first electrostatically accelerated to 5.7 keV, followed by further acceleration to 100 keV using a radio-frequency quadrupole with an intensity of 2~10?3???+/pulse. The transverse normalized rms emittance of the accelerated muons in the horizontal and vertical planes were 0.85}0.25?(s?t?a?t)+0.22?0.13?(syst)??????mm?mrad and 0.32}0.03?(stat)+0.05?0.02?(syst)?????mm?mrad, respectively. The measured emittance values demonstrated phase-space reduction by a factor of 2.0 ~102 (horizontal) and 4.1 ~102 (vertical) allowing good acceleration efficiency. These results pave the way to realize the first-ever muon accelerator for a variety of applications in particle physics, material science, and other fields. en-copyright= kn-copyright=

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=208 cd-vols= no-issue=5 article-no= start-page=e00103-26 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knockout of tusA confers cationic antimicrobial resistance via fur and omp genes in Escherichia coli en-subtitle= kn-subtitle= en-abstract= kn-abstract=tRNA 2-thiouridine synthesizing protein A (TusA), a sulfur-carrier protein, plays a crucial role in tRNA sulfur modification. Several studies have reported that tusA deficiency affects iron?sulfur (Fe?S) homeostasis in addition to tRNA sulfur modification, resulting in pleiotropic phenotypes. In this study, we analyzed the phenotype of tusA-deficient Escherichia coli and its underlying mechanisms. Although the Keio tusA knockout strain showed increased swimming motility and flagellar biosynthesis, these phenotypes were not restored by tusA complementation. Genome resequencing of the original Keio tusA knockout strain identified an unintended secondary mutation in lrhA, a transcriptional regulator of flagellar and chemotaxis genes. This secondary mutation impaired lrhA function, contributing to enhanced flagellar synthesis and swimming motility, as well as altered global gene expression. A tusA knockout strain in which the secondary mutation was corrected (ƒ¢tusA) exhibited reduced swimming motility compared with the wild-type strain, despite showing no abnormalities in flagellar formation. Furthermore, ƒ¢tusA displayed increased resistance to cationic antibacterial agents, including cetyltrimethylammonium bromide, cetylpyridinium chloride, and protamine sulfate. The reduced motility caused by tusA deletion was observed independently of Fur, a global regulator of iron homeostasis, whereas resistance to cationic antibacterial agents was abolished in the fur knockout background. In addition, altered expression of outer membrane protein (omp) genes was observed in ƒ¢tusA, and deletion of these omp genes abolished resistance to cationic antibacterial agents. Together, these results indicate that, by disentangling the phenotypic effects of tusA deletion from those of the unintended secondary mutation, loss of tusA confers resistance to cationic antibacterial agents through a Fur-dependent and Omp-dependent mechanism. en-copyright= kn-copyright= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataKiho en-aut-sei=Nakata en-aut-mei=Kiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKoichiro en-aut-sei=Yamada en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UnemeMio en-aut-sei=Uneme en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=tusA kn-keyword=tusA en-keyword=fur kn-keyword=fur en-keyword=Escherichia coli kn-keyword=Escherichia coli en-keyword=cationic antimicrobial agents kn-keyword=cationic antimicrobial agents END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=rbae144 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimizing ƒÀ-TCP with E-rhBMP-2-infused fibrin for vertical bone regeneration in a mouse calvarium model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective reconstruction of large bone defects, particularly in thickness, remains one of the major challenges in orthopedic and dental fields. We previously produced an Escherichia coli-based industrial-scale GMP-grade recombinant human bone morphogenetic protein-2 (E-rhBMP-2) and showed that the combination of E-rhBMP-2 with beta-tricalcium phosphate (ƒÀ-TCP/E-rhBMP-2) can effectively promote bone reconstruction. However, the limited mechanical strength and poor morphology retention of ƒÀ-TCP granules are key points that need optimization to obtain more effective grafts and further expand its clinical applications. Therefore, we combined ƒÀ-TCP/E-rhBMP-2 with fibrin gel to enhance its mechanical properties and usability for vertical bone regeneration. We investigated the mechanical properties and vertical bone regeneration effects of the materials applied, with or without fibrin containing E-rhBMP-2, in a calvarial defect model in mice. Compression tests were conducted to assess the initial stability of the materials. Scanning electron microscopy and Fourier transform infrared spectroscopy were conducted to characterize the presence of fibrin on the scaffold. After 4 and 12?weeks of implantation, micro-computed tomography and histological and immunofluorescent analyses were performed to assess the morphology and volume of the newly formed bone. The fibrin-containing groups had significantly higher initial mechanical strength and higher ability to maintain their morphology in vivo compared to the counterparts without fibrin. However, fibrin gel alone suppressed the bone formation ability of ƒÀ-TCP/E-rhBMP-2 whereas the presence of high doses of E-rhBMP-2 in fibrin gel resulted in material resorption and enhanced new bone formation. In conclusion, fibrin gel significantly improved the mechanical strength and surgical manageability of the ƒÀ-TCP/E-rhBMP-2 scaffold, and the addition of E-rhBMP-2 to the fibrin gel further enhanced the vertical bone regeneration and initial structural integrity of the scaffold. en-copyright= kn-copyright= en-aut-name=ZhaoKun en-aut-sei=Zhao en-aut-mei=Kun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuXindi en-aut-sei=Mu en-aut-mei=Xindi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=XieShichao en-aut-sei=Xie en-aut-mei=Shichao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YonezawaTomoko en-aut-sei=Yonezawa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=OohashiToshitaka en-aut-sei=Oohashi en-aut-mei=Toshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Division of Dental Biomaterials, Tohoku University Graduate School of Dentistry kn-affil= affil-num=8 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=BMP-2 kn-keyword=BMP-2 en-keyword=fibrin kn-keyword=fibrin en-keyword=vertical bone regeneration kn-keyword=vertical bone regeneration en-keyword=biocompatible materials kn-keyword=biocompatible materials END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=12 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Early Response After Radiation Therapy on Three-Dimensional Oral Cancer Model Using Patient-Derived Cancer-Associated Fibroblasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Cancer-associated fibroblasts (CAFs), which are an important component of the tumor microenvironment, have been reported to have an adverse effect on conventional radiotherapy. This study aims to elucidate the effects of CAFs in boron neutron capture therapy (BNCT) using a three-dimensional (3D) oral cancer model. Methods: Three-dimensional cancer models were fabricated using patient-derived CAFs or patient-derived normal oral fibroblasts (NOFs) and a human oral squamous cell carcinoma cell line. Each 3D cancer model was performed with either a conventional X-ray treatment or BNCT and additionally analyzed histomorphologically. Results: The 3D oral cancer-CAFs model demonstrated a greater depth of cancer cell invasion than the 3D oral cancer-NOFs model. Radiation therapy for the 3D oral cancer models indicated a trend for decreasing cancer cell invasion and cell number with dose dependence in both X-ray and BNCT. In comparison with X-rays, BNCT showed a consistent increase in the number of NOFs and a significant reduction in the number of CAFs. Conclusions: BNCT for the 3D oral cancer model was shown to be effective against cancer cells and CAFs but not against NOFs, indicating its usefulness as a minimally invasive treatment for advanced cancer. Furthermore, it is indicated that the 3D oral cancer-CAFs model is a valuable tool to evaluate cancer treatment and research, particularly in high-grade malignant tumors with invasion. en-copyright= kn-copyright= en-aut-name=YamamotoIzumi en-aut-sei=Yamamoto en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IgawaKazuyo en-aut-sei=Igawa en-aut-mei=Kazuyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoNatsuko en-aut-sei=Kondo en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakuraiYoshinori en-aut-sei=Sakurai en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=HuangPeng en-aut-sei=Huang en-aut-mei=Peng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MichiueHiroyuki en-aut-sei=Michiue en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=IzumiKenji en-aut-sei=Izumi en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=2 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=3 en-affil=Particle Radiation Oncology Center, Institute for Integrated Radiation and Nuclear Science, Kyoto University kn-affil= affil-num=4 en-affil=Particle Radiation Oncology Center, Institute for Integrated Radiation and Nuclear Science, Kyoto University kn-affil= affil-num=5 en-affil=Department of Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=8 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Division of Biomimetics, Faculty of Dentistry & Graduate School of Medical and Dental Sciences, Niigata University kn-affil= en-keyword=3D model kn-keyword=3D model en-keyword=oral cancer kn-keyword=oral cancer en-keyword=patient-derived cells kn-keyword=patient-derived cells en-keyword=cancer-associated fibroblasts kn-keyword=cancer-associated fibroblasts en-keyword=radiation treatment kn-keyword=radiation treatment en-keyword=boron neutron capture therapy kn-keyword=boron neutron capture therapy en-keyword=malignant tumors kn-keyword=malignant tumors END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=57 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical conductivity measurements of rhyolitic glass at high pressure and high temperature en-subtitle= kn-subtitle= en-abstract= kn-abstract=We performed electrical conductivity measurements of rhyolite glasses across the glass transition temperature at 1 GPa. Our experimental data show that, in the Arrhenius plot, the conductivity of rhyolite with 0.2 wt% H2O has an inflection point between around 760 K, while for rhyolite with 4.9 wt% H2O the gradient changes between 685 and 825 K. These inflection points correlate with the glass transition temperature, and are compared with results of previous experiments. The degree of welding of clastic and hydrous rock can be constrained by estimating glass transition temperatures of volcanic rocks combined with measurements of electrical conductivity structures obtained from electromagnetic soundings beneath volcanic bodies. This, in turn, can be used to aid predictions of volcanic eruption. en-copyright= kn-copyright= en-aut-name=HaraguchiYusuke en-aut-sei=Haraguchi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Fuji-TaKiyoshi en-aut-sei=Fuji-Ta en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamotoMasashi en-aut-sei=Nakamoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiMasanori en-aut-sei=Suzuki en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaToshihiro en-aut-sei=Tanaka en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=2 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=5 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= affil-num=6 en-affil=Graduate School of Engineering, The University of Osaka kn-affil= en-keyword=Electrical conductivity kn-keyword=Electrical conductivity en-keyword=Glass transition temperature kn-keyword=Glass transition temperature en-keyword=melt kn-keyword=melt en-keyword=clastics kn-keyword=clastics END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=5 article-no= start-page=1705 end-page=1715 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distinct interleukin-6 production in IPL and TAFRO subtypes of idiopathic multicentric Castleman disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Idiopathic multicentric Castleman disease (iMCD) is a rare lymphoproliferative disorder characterized by systemic inflammation and lymphadenopathy. Two major clinical subtypes, idiopathic plasmacytic lymphadenopathy (iMCD-IPL) and iMCD with thrombocytopenia, anasarca, fever, renal dysfunction/reticulin fibrosis, and organomegaly (iMCD-TAFRO), have distinct pathophysiological mechanisms. While interleukin-6 (IL-6) is known to be elevated in iMCD, differences in the sources of IL-6 production between subtypes remain unclear. We examined the source of IL-6 production and its transcriptional regulation across iMCD subtypes using immunohistochemistry, in situ hybridization, and gene expression profiling. Immunohistochemistry and in situ hybridization revealed that plasma cells were the predominant IL-6-expressing cells in iMCD-IPL, whereas vascular endothelial cells expressed IL-6 in iMCD-TAFRO. Plasma cells exhibited stronger IL-6 protein expression in iMCD-IPL than in iMCD-TAFRO. Gene expression analysis revealed upregulation of XBP1, MZB1, DERL3, SSR4, FKBP11, FKBP2, PIM2, RABAC1, and SDF2L1 in iMCD-IPL, implicating endoplasmic reticulum stress and plasma cell differentiation in IL-6 dysregulation. Our findings suggest that XBP1-mediated IL-6 production may contribute to the pathogenesis of iMCD-IPL, potentially explaining its favorable responses to IL-6 blockade therapy. In contrast, IL-6 production in iMCD-TAFRO may be predominantly from vascular endothelial cells, suggesting that elevated serum IL-6 is a secondary phenomenon of the cytokine storm in this subtype. Future studies should clarify how proteomics and gene expression profiling could inform subtype-specific therapeutic strategies in iMCD. en-copyright= kn-copyright= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaRio en-aut-sei=Yamada en-aut-mei=Rio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaratakeTomoka en-aut-sei=Haratake en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=ChijimatsuRyota en-aut-sei=Chijimatsu en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoToshihiro en-aut-sei=Ito en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KogaTomohiro en-aut-sei=Koga en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OchiSayaka en-aut-sei=Ochi en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaharaYuri en-aut-sei=Kawahara en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=UetaHimawari en-aut-sei=Ueta en-aut-mei=Himawari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TakedaYudai en-aut-sei=Takeda en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=GonzalezMichael V. en-aut-sei=Gonzalez en-aut-mei=Michael V. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=FajgenbaumDavid C. en-aut-sei=Fajgenbaum en-aut-mei=David C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Van RheeFrits en-aut-sei=Van Rhee en-aut-mei=Frits kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=MomoseShuji en-aut-sei=Momose en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 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=18 ORCID= affil-num=1 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Division of Hematology/Oncology, Mayo Clinic kn-affil= affil-num=4 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital, Okayama, Japan;

Using Hayabusa2 ONC-T mosaics for mapping, we present the most extensive global boulder dataset to date, representing an eleven-fold increase over the earliest survey and greater completeness than later AI-based estimates. Crucially, this work provides the first global boulder orientation dataset. The cumulative size-frequency distribution follows a power-law slope of ??2.665?}?0.066 (boulders???3 m), indicating its fragmented nature. Boulder density is lower along the equatorial ridge, consistent with regolith accumulation during earlier YORP-driven spin-up and poleward migration of blocks during the present spin-down phase. Orientation analyses reveal systematic hemispheric trends in what we define as slope-breaker zones (i.e., regions of high slope differentials), with NW?SE alignment in the northern hemisphere and NE?SW in the southern hemisphere, but absent at the equatorial ridge and poles. We interpret these as reorientations that developed during downslope boulder migration, as despite ongoing spin-down, the current spin rate remains high enough to drive such motion. In addition, fresh craters exhibit locally heightened boulder densities, recording ongoing resurfacing by impact events that exhume buried subsurface boulders and segregate them from finer regolith via seismic shaking induced granular convection. Together, these results yield new insights into rubble-pile surface evolution, rotational dynamics, and impact-driven resurfacing, with boulder orientations providing critical evidence of spin-related downslope transport and establish a framework for comparative asteroid studies. en-copyright= kn-copyright= en-aut-name=RayAditya en-aut-sei=Ray en-aut-mei=Aditya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=VincentLisa M. en-aut-sei=Vincent en-aut-mei=Lisa M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikuchiHiroshi en-aut-sei=Kikuchi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HemmiRyodo en-aut-sei=Hemmi en-aut-mei=Ryodo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Orm?Jens en-aut-sei=Orm? en-aut-mei=Jens kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=International Research School of Planetary Sciences, Universit?

Focusing on well characterized Holocene and Pleistocene New Zealand sinters, we utilize synchrotron-X-ray fluorescence (sXRF) and Ga K-edge X-ray absorption near edge structure (XANES) spectroscopy to examine the spatial distribution of Ga as well as its changing coordination number. Ga+3 is the only observed oxidation state in the analyzed sinters. Gallium is predominantly found in tetrahedral coordination in sinter deposited from alkali chloride fluids, with analyses best matching Ga-aluminosilicate standards. However, Ga coordination is octahedral in sinter samples that have undergone alteration by acidic fluids/gases, associated with a change in hydrology from alkali-chloride to acid-sulfate fluid conditions. High Ga concentrations are found associated with both these coordination environments, with a heterogeneous distribution. Octahedral Ga is observed both as particles and in larger regions affected by Fe-rich fluid overprinting. The combined use of sXRF and XANES demonstrates an ability to fingerprint diagenesis and alteration in these complex geothermal settings where tetrahedral and octahedral Ga co-exist. The transition from tetrahedral to octahedral Ga also appears to mimic the inferred natural process forming lateritic bauxite deposits, where remobilized tetrahedral Ga is reconcentrated and adsorbed to oxides. A similar process may occur for sinter Ga enrichment, whereby introduced Ga in acidic conditions is adsorbed to oxide phases as the Fe-rich secondary fluids infiltrate porous sinter material. en-copyright= kn-copyright= en-aut-name=RoweM.C. en-aut-sei=Rowe en-aut-mei=M.C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CampbellK.A. en-aut-sei=Campbell en-aut-mei=K.A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=StallardD.A. en-aut-sei=Stallard en-aut-mei=D.A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LyonB. en-aut-sei=Lyon en-aut-mei=B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LangendamA. en-aut-sei=Langendam en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KalininaE. en-aut-sei=Kalinina en-aut-mei=E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamanakaM. en-aut-sei=Yamanaka en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaR. en-aut-sei=Tanaka en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ChristopherT. en-aut-sei=Christopher en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=RuffS.W. en-aut-sei=Ruff en-aut-mei=S.W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NersezovaE. en-aut-sei=Nersezova en-aut-mei=E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtaT. en-aut-sei=Ota en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HamiltonA. en-aut-sei=Hamilton en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=School of Environment, University of Auckland kn-affil= affil-num=2 en-affil=School of Environment, University of Auckland kn-affil= affil-num=3 en-affil=School of Environment, University of Auckland kn-affil= affil-num=4 en-affil=School of Environment, University of Auckland kn-affil= affil-num=5 en-affil=Australian Synchrotron Facility (Ansto) kn-affil= affil-num=6 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=7 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=8 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=9 en-affil=School of Chemical Sciences, University of Auckland kn-affil= affil-num=10 en-affil=Arizona State University, School of Earth And Space Exploration kn-affil= affil-num=11 en-affil=School of Environment, University of Auckland kn-affil= affil-num=12 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=13 en-affil=School of Environment, University of Auckland kn-affil= en-keyword=Hot springs kn-keyword=Hot springs en-keyword=New Zealand kn-keyword=New Zealand en-keyword=Gallium kn-keyword=Gallium en-keyword=Sinter kn-keyword=Sinter en-keyword=Synchrotron radiation kn-keyword=Synchrotron radiation en-keyword=Coordination number kn-keyword=Coordination number END start-ver=1.4 cd-journal=joma no-vol=236 cd-vols= no-issue= article-no= start-page=112768 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An algorithm to calculate physical density of biomedical objects having 3 ? Zeff ? 20: an application study using clinical photon-counting computed tomography equipment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, photon-counting computed tomography (PC-CT) devices have become clinically available for X-ray diagnosis, and developments of analysis algorithms to generate various quantitative images have focused attention. This study proposes an algorithm to calculate the effective physical density (ƒÏeff) of biological objects having an effective atomic number (Zeff) of 3?20. In our procedure, ƒÏeff was determined when fitting the interaction cross sections (ƒÐs) to the measured linear attenuation coefficients (ƒÊs), which were determined from virtual monochromatic images (VMIs). In this process, the Zeff was analyzed in advance, and this information was fed back to the ƒÏeff analysis. A key feature of our procedure is that it does not require calibration processes based on specific substances, which allow us to analyze any substance without making assumptions.
To validate the availability of the proposed algorithm, we conducted an experiment using a clinical PC-CT scanner. A multi-energy CT phantom, a water phantom, an in-house low-density phantom, food samples, and a chest phantom were scanned. The results showed that our procedure can calculate ƒÏeff of water with an uncertainty of 4.5%. The academic significance of the present research results lies in demonstrating that the factors contributing to contrast, previously obtained from CT values, can be physically interpreted using information from Zeff and ƒÏeff. This analysis cannot be performed with conventional single-energy CT scanners and is possible with PC-CT and dual-energy CT scanners. Our novel procedure is expected to provide useful additional information in X-ray diagnosis. 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=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=MitaniMana en-aut-sei=Mitani en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=5 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= en-keyword=Computed tomography kn-keyword=Computed tomography en-keyword=Photon counting kn-keyword=Photon counting en-keyword=Physical density image kn-keyword=Physical density image en-keyword=Virtual monochromatic image kn-keyword=Virtual monochromatic image en-keyword=Diagnostic X-rays kn-keyword=Diagnostic X-rays END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=12 end-page= 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=Interfacial Bond Strength of Resin Cement to Polyetheretherketone (PEEK) Using Experimental Primers Doping Multifunctional Methacrylate and Acrylate Monomers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Polyetheretherketone (PEEK) is a high-performance thermoplastic polymer with low surface energy, chemical inertness, and a highly crystalline structure, which limit durable adhesion to resin-based materials and require improved bonding strategies. This in vitro study evaluated the effect of incorporating multifunctional methacrylate (TMPTMA) and acrylate monomers (A-TMPT and A-DPH) into an experimental primer on the 24 h shear bond strength (SBS) of resin cement to PEEK (n = 6 per group). Experimental primers were prepared by adding varying amounts (100?500 ?L) of each multifunctional monomer to a UDMA/MMA-based primer, and SBS was measured after cementation with a dual-cure resin cement. TMPTMA-containing primers produced median SBS values of approximately 10?12 MPa, while acrylate-based primers showed slightly higher values, particularly at higher concentrations, reaching up to ~15.8 MPa; however, no statistically significant improvement over the control group was observed (p > 0.05). Failure modes were predominantly mixed across all conditions. These findings indicate that multifunctional monomers, despite their potential to enhance cross-link density and wetting, do not substantially overcome the intrinsic adhesion-resistant nature of polished PEEK. The results underscore that monomer modification alone is insufficient and that effective adhesion to PEEK likely requires integrated strategies combining chemical activation with mechanical surface conditioning. en-copyright= kn-copyright= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KodamaNaoki en-aut-sei=Kodama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaYuki en-aut-sei=Tanaka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuwaharaMiho en-aut-sei=Kuwahara en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=2 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=3 en-affil=Okayama University Dental School kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=5 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=6 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=PEEK kn-keyword=PEEK en-keyword=functional monomer kn-keyword=functional monomer en-keyword=bond strength kn-keyword=bond strength en-keyword=methacrylate kn-keyword=methacrylate en-keyword=acrylate kn-keyword=acrylate END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=6 article-no= start-page=998 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260613 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Disease-Suppressive Activity of Lecithin Against Foliar Infection by Rhizoctonia solani Isolates in Cabbage, Rice, and Brachypodium distachyon en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rhizoctonia solani is a necrotrophic phytopathogenic fungus that causes disease in various crops. In agriculture, many crops suffer from root or seedling rot caused by this soil-borne pathogen, whereas cabbage and rice develop lesion-like symptoms on aboveground tissues. Diseases caused by R. solani are generally controlled using chemical fungicides; however, environmentally friendly alternatives are needed for sustainable agriculture. In this study, we evaluated the efficacy of lecithin, a mixture of phospholipids previously registered in Japan as an agrochemical for controlling cucumber powdery mildew, against Rhizoctonia diseases. In cabbage, foliar spraying of 0.2?1.0% soybean lecithin effectively suppressed leaf symptoms caused by R. solani isolate RhiCa-2, which was identified as AG-1 IB. In rice and Brachypodium distachyon, 0.2?1.0% lecithin significantly suppressed leaf symptoms induced by R. solani AG-1 IA. Hyphal staining of inoculated leaves revealed reduced hyphal density on lecithin-treated leaves. Consistently, hyphal growth of R. solani on cellophane placed on water agar was retarded by lecithin treatment. However, 5.0% lecithin induced phytotoxicity in B. distachyon. Egg yolk-derived lecithin also exhibited disease-suppressive activity in cabbage and B. distachyon, with efficacy comparable to that of soybean lecithin under the conditions tested. These results suggest that lecithin suppresses foliar infection by R. solani, at least in part, through direct inhibitory effects on fungal hyphae, and may serve as a potential alternative material for disease control in sustainable crop production. en-copyright= kn-copyright= en-aut-name=CuongTran Xuan en-aut-sei=Cuong en-aut-mei=Tran Xuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsanoMisaki en-aut-sei=Asano en-aut-mei=Misaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HonmaDaiki en-aut-sei=Honma en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoedaMoeko en-aut-sei=Soeda en-aut-mei=Moeko 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=IkedaKentaro en-aut-sei=Ikeda en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=School of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=School of Agriculture, 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= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University, Okayama 700-8530, Japan 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=Faculty of Bioscience and Applied Chemistry, Hosei University kn-affil= affil-num=11 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Rhizoctonia solani kn-keyword=Rhizoctonia solani en-keyword=foliar symptoms kn-keyword=foliar symptoms en-keyword=leaf infection kn-keyword=leaf infection en-keyword=cabbage kn-keyword=cabbage en-keyword=rice kn-keyword=rice en-keyword=Brachypodium distachyon kn-keyword=Brachypodium distachyon END
