We report the case of an 81-year-old man with severe emphysema and a history of esophagectomy who presented with sudden-onset dyspnea. Chest computed tomography revealed bilateral pneumothorax with pleuro-pleural communication. Although bilateral chest tube drainage was performed, the primary side of air leakage could not be identified preoperatively. After induction of general anesthesia, a double-lumen endotracheal tube clamping test identified the right pleural cavity as the source of air leakage, thereby enabling appropriate thoracoscopic surgery. en-copyright= kn-copyright= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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=8 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=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and 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 Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=simultaneous bilateral spontaneous pneumothorax kn-keyword=simultaneous bilateral spontaneous pneumothorax en-keyword=pleuro-pleural communication kn-keyword=pleuro-pleural communication END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=219 end-page=223 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=Common Bile Duct Stone Formed Around an Ingested Fish Bone en-subtitle= kn-subtitle= en-abstract= kn-abstract=An 86-year-old man presented with epigastric pain. He had previously undergone distal gastrectomy with Roux-en-Y reconstruction. Computed tomography (CT) revealed a 32×17 mm common bile duct (CBD) stone with an internal 20 mm linear hyperdense component. Endoscopic removal was unsuccessful due to the size and impaction of the stone. Open choledochotomy retrieved multiple stones and a calcified fish bone, which was confirmed by infrared spectroscopy using the potassium bromide (KBr) wafer method. Although fish bone ingestion is relatively common, this case highlights that such foreign bodies can occasionally serve as a nidus for CBD stone formation, leading to unexpected and clinically significant pathologies. When CT demonstrates a linear high-attenuation intraductal structure, clinicians should suspect a bone fragment and follow a stepwise approach, considering early surgical intervention when endoscopic extraction is unsuccessful or likely to be challenging. en-copyright= kn-copyright= en-aut-name=HigashiKaitaro en-aut-sei=Higashi en-aut-mei=Kaitaro 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=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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 Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=common bile duct stone kn-keyword=common bile duct stone en-keyword=fish bone kn-keyword=fish bone en-keyword=Roux-en-Y kn-keyword=Roux-en-Y en-keyword=choledochotomy kn-keyword=choledochotomy END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=213 end-page=217 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=A Novel Flap Design to Reduce Urethral Complications in Anterolateral Thigh Phalloplasty: The Pipe Flap Technique en-subtitle= kn-subtitle= en-abstract= kn-abstract=Phalloplasty is one of the most challenging procedures in gender-affirming surgery, and urethral complications remain common despite numerous preventive efforts. No definitive solution has been established, and many patients still require subsequent corrective procedures. We designed a novel anterolateral thigh flap that creates a planned external fistula at the penile base to mitigate urethral complications. The fistula was closed in a second-stage procedure one year later, and the postoperative course was uneventful. We report a case of a transgender man treated with this two-stage “pipe flap” technique, resulting in satisfactory urinary function. This approach may offer a safe and less invasive option for mitigating urethral complications in phalloplasty. en-copyright= kn-copyright= en-aut-name=ImaiToshiro en-aut-sei=Imai en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeToshiyuki en-aut-sei=Watanabe en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeShiho en-aut-sei=Watanabe en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayashiMasanobu en-aut-sei=Hayashi en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Tohoku University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic and Reconstructive Surgery, National Hospital Organization Tokyo Medical Center kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Tohoku University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gender Center, Okayama University Hospital kn-affil= en-keyword=phalloplasty kn-keyword=phalloplasty en-keyword=surgical flaps kn-keyword=surgical flaps en-keyword=transgender persons kn-keyword=transgender persons END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=203 end-page=212 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=Evaluation of Bone Mineral Density and Bone Structure in the Cervical and Thoracic Spine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dropped head syndrome, which has been increasingly reported in recent years, requires correction of cervical kyphosis and may require long-range fixation extending from the cervical to the thoracic spine. Assessing vertebral bone structure may be important for preventing instrumentation failure in the upper thoracic spine, which is a potential complication of surgery. In this study, we evaluated volumetric bone mineral density, trabecular bone porosity, and cortical calcification in the cervical and upper thoracic spine using three-dimensional (3D) trabecular structure measurement software. The study included 79 patients with cervical spine disorders who underwent various surgical procedures and preoperative imaging, including dual-energy X-ray absorptiometry and computed tomography (CT) scans from C3 to Th3. Quantitative analysis using specialized software assessed volumetric bone mineral density and trabecular and cortical bone parameters, and statistical analyses were performed to examine correlations between imaging metrics and indicators of bone fragility. Two-dimensional CT evaluation revealed different trends between cancellous and cortical bone in the cervical and thoracic spine, suggesting that detailed 3D evaluation may also be important. en-copyright= kn-copyright= en-aut-name=AoyamaShingo en-aut-sei=Aoyama en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaTerumasa en-aut-sei=Ikeda en-aut-mei=Terumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NangoNobuhito en-aut-sei=Nango en-aut-mei=Nobuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoKoji en-aut-sei=Goto en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Kindai University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Kindai University Hospital kn-affil= affil-num=3 en-affil=Ratoc System Engineering Co., Ltd. kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Kindai University Hospital kn-affil= en-keyword=cervical spine kn-keyword=cervical spine en-keyword=volumetric bone mineral density kn-keyword=volumetric bone mineral density en-keyword=three-dimensional trabecular structure measurement kn-keyword=three-dimensional trabecular structure measurement END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=195 end-page=202 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=HIP COMPASS®: A Mechanical Intraoperative Navigation Guide Associated with Improved Revision-Free Implant Survivorship after Ceramic-on-Ceramic Total Hip Arthroplasty at Minimum 10-Year Follow-up en-subtitle= kn-subtitle= en-abstract= kn-abstract=HIP COMPASS® has demonstrated improved accuracy in intraoperative support for the acetabular component insertion angle. We assessed long-term revision-free implant survivorship following total hip arthroplasty (THA) using HIP COMPASS, with ≥10 years of follow-up. We retrospectively analyzed 210 hips of 186 patients who underwent cementless THA with ceramic-on-ceramic bearing couples, with or without HIP COMPASS. The mean follow-up duration was 10.8 years in the HIp COMPASS group and 12.7 years in the control group. Overall, 86.0% and 78.2% of cups were placed within Lewinnek’s safe zone with and without HIP COMPASS, respectively. Variability in radiographic inclination and anteversion was greater in the control group than in the HIP COMPASS group. Dislocation rates were 3.2% in the control group and 1.2% in the HIP COMPASS group, with no significant difference between groups. The control group had a significantly higher revision rate than the HIP COMPASS group (7.3% vs. 1.2%). Use of HIP COMPASS was associated with improved long-term revision-free implant survivorship over ≥ 10 years and more consistent acetabular component positioning at an appropriate insertion angle, which may contribute to stable initial fixation. en-copyright= kn-copyright= en-aut-name=TeiYoshiaki en-aut-sei=Tei en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraKeishi en-aut-sei=Kimura en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoYuki en-aut-sei=Hirano en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SudaKen en-aut-sei=Suda en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawashimaHiroyuki en-aut-sei=Kawashima en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=3 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=5 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=6 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=7 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= en-keyword=HIP COMPASS® kn-keyword=HIP COMPASS® en-keyword=survivorship kn-keyword=survivorship en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=ceramic-on-ceramic kn-keyword=ceramic-on-ceramic END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=185 end-page=193 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reducing Hesitation in Resuscitation: Educational Effects of a Female-Appearing Simulator in Basic Life Support Training en-subtitle= kn-subtitle= en-abstract= kn-abstract=Women are less likely than men to receive timely defibrillation during out-of-hospital cardiac arrest. We investigated whether using a simulator that is visually modified to resemble a female affects learners’ attitudes, knowledge, and performance in basic life support (BLS) training. In a BLS simulation training, first-year medical students (n=220) used a standard gender-neutral simulator (control group) or a modified simulator with a female-like appearance (intervention group). Pre- and post-training questionnaires concerning attitudes and knowledge plus a post-training skills evaluation assessed the students’ training outcomes. The intervention group initiated chest compressions significantly faster than the control group (33.1 vs. 39.8 sec, p<0.01) and achieved a significantly higher rate of correct AED pad placement (64.2% vs. 38.5%, p<0.01). While performing the resuscitation on the female-appearing manikin, the intervention group showed significantly greater increases in self-efficacy (p<0.01) and larger decreases in discomfort about removing the patient’s clothes (p<0.01). They were also significantly more likely to recognize that chest compressions can be performed (p=0.016) and AED pads can be applied (p=0.015) without removing the patient’s underwear. Using a female-appearing simulator in BLS training was thus associated with faster chest compression initiation, more accurate AED pad placement, and improved gender-sensitive attitudes and knowledge. en-copyright= kn-copyright= en-aut-name=KuboTakuya en-aut-sei=Kubo en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=resuscitation kn-keyword=resuscitation en-keyword=basic life support kn-keyword=basic life support en-keyword=female simulator kn-keyword=female simulator en-keyword=medical education kn-keyword=medical education en-keyword=gender bias kn-keyword=gender bias END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=179 end-page=184 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=Oral Eicosapentaenoic Acid and Paclitaxel-Associated Peripheral Neuropathy: A Retrospective Study at Okayama University Hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=This retrospective study investigated whether eicosapentaenoic acid (EPA) reduces paclitaxel-associated chemotherapy-induced peripheral neuropathy (CIPN) and acute neuropathic pain in dyslipidemic cancer patients. The medical records of cancer patients treated with paclitaxel or nab-paclitaxel at Okayama University Hospital between January 2018 and December 2022 were reviewed. Patients receiving concomitant therapy for dyslipidemia were categorized as EPA users or non-EPA users. Numbness and pain severity were extracted from medical records. The primary endpoint was the change from baseline in Common Terminology Criteria for Adverse Events (CTCAE) grade for peripheral neuropathy and pain; groups were analyzed using the Mann–Whitney U test. Of 184 eligible patients, 18 received EPA. Bleeding events were more frequent in the EPA group; however, changes in numbness and pain did not differ significantly between groups at any time point. Overall, EPA did not show a preventive effect on paclitaxel-associated CIPN or acute neuropathic pain. Future studies should evaluate EPA in combination with other neuroprotective agents to better define its potential role in CIPN prevention. 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=KatayamaHideki en-aut-sei=Katayama en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= affil-num=1 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=eicosapentaenoic acid kn-keyword=eicosapentaenoic acid en-keyword=cancer patients kn-keyword=cancer patients en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=peripheral neuropathy kn-keyword=peripheral neuropathy en-keyword=cancer pain kn-keyword=cancer pain END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=169 end-page=178 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Peripheral Blood T-Cell Receptor Repertoire and Host Immune Background in Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=The association between peripheral blood T-cell receptor (TCR) repertoire and chemotherapy response remains unclear. We evaluated peripheral blood TCR repertoire and gut microbiota in 21 breast cancer patients receiving neoadjuvant chemotherapy (NAC) who were enrolled in the SBP-14 prospective cohort study between October 2019 and March 2022. We analyzed stool samples obtained pre-NAC and peripheral blood samples obtained pre- and post-NAC. The primary endpoint was the association between baseline peripheral blood TCR repertoire and treatment response. Eleven patients (52%) had hormone receptor-positive breast cancer. All patients received anthracyclines and taxanes, with anti-HER2 therapy for HER2-positive disease. TCR diversity (TCR alpha chain [TRA], p=0.095; TCR beta chain [TRB], p=0.051) and clonality (TRA, p=0.271; TRB, p=0.500) were not significantly associated with treatment response. Gut microbiota diversity was not correlated with TCR diversity (TRA: ρ=0.046, p=0.845; TRB: ρ=0.021, p=0.929); however, three bacterial orders (Erysipelotrichales, Bacillales, and Pasteurellales) were significantly associated with TCR repertoire. Baseline TCR repertoire was not associated with treatment response in this cohort of breast cancer patients. en-copyright= kn-copyright= en-aut-name=NakamuraYuki en-aut-sei=Nakamura en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamotoTakayuki en-aut-sei=Iwamoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KajiwaraYukiko en-aut-sei=Kajiwara en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidaAkira en-aut-sei=Hida en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamotoShogo en-aut-sei=Nakamoto en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiYuichiro en-aut-sei=Miyoshi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkedaMasahiko en-aut-sei=Ikeda en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OgataRyohei en-aut-sei=Ogata en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoikeYoshikazu en-aut-sei=Koike en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NomuraTsunehisa en-aut-sei=Nomura en-aut-mei=Tsunehisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TanakaKatsuhiro en-aut-sei=Tanaka en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NakashimaKazutaka en-aut-sei=Nakashima en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YamatsujiTomoki en-aut-sei=Yamatsuji en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=2 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=3 en-affil=Department of Breast Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Pathology, Matsuyama Shimin Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Breast Endocrine Surgery, Kagawa Prefectural Center Hospital kn-affil= affil-num=7 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Breast and Thyroid Surgery, Fukuyama City Hospital kn-affil= affil-num=9 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=10 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=11 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=12 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=13 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=14 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=15 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=16 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School Hospital kn-affil= en-keyword=TCR repertoire kn-keyword=TCR repertoire en-keyword=gut microbiota kn-keyword=gut microbiota en-keyword=neoadjuvant chemotherapy kn-keyword=neoadjuvant chemotherapy en-keyword=breast cancer kn-keyword=breast cancer END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=3 article-no= start-page=159 end-page=168 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Self-Reported Adolescent Menstrual Symptoms and Delayed Gynecologic Consultation among Japanese Women with Endometriosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endometriosis symptoms often first appear during adolescence, yet delays in seeking gynecologic consultation remain a persistent challenge worldwide. Despite growing international evidence, the specific patterns of symptom recognition and consultation delay among Japanese women — particularly in relation to self-monitoring behaviors and cultural barriers — remain poorly understood. This study aimed to provide foundational data to guide menstrual education and preconception care strategies by conducting a cross-sectional online survey with retrospective recall among women with endometriosis to assess menstrual characteristics and symptom patterns from adolescence to initial care seeking. The survey was conducted in Japan in January 2024 and enrolled 166 women with endometriosis and 200 controls. Participants reported current and adolescent menstrual characteristics, symptom recognition, analgesic and low-dose estrogen–progestin use, school/work impact, and age at first gynecologic consultation for menstrual problems. Women with endometriosis reported heavier bleeding, stronger pain, and greater school/work absence than controls, both currently and retrospectively. The median age at first recognition of heavy bleeding or school/work absence was 16 years, whereas consultation occurred at approximately 21-23 years, indicating a consultation delay of 5-6 years. Notably, while self-monitoring of symptoms was more frequent among women with endometriosis, it only modestly shortened consultation delays. This study provides evidence from Japan that consultation delay persists despite active self-monitoring of symptoms, highlighting the influence of educational and cultural barriers on health-seeking behavior. These findings underscore the importance of integrating menstrual education with clinical guidance to promote timely gynecologic consultation. en-copyright= kn-copyright= en-aut-name=IkedaTomoko en-aut-sei=Ikeda en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakatsukaMikiya en-aut-sei=Nakatsuka en-aut-mei=Mikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=endometriosis kn-keyword=endometriosis en-keyword=adolescence kn-keyword=adolescence en-keyword=menstrual disorders kn-keyword=menstrual disorders en-keyword=consultation delay kn-keyword=consultation delay en-keyword=health-seeking behavior kn-keyword=health-seeking behavior END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260617 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Age-related changes in the orbital pulley array of older Japanese adults with acquired exotropia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To evaluate age-related changes in the orbital pulley array using magnetic resonance imaging (MRI) in older Japanese adults with acquired exotropia (XT) compared with young healthy participants (YHP).
Methods: In this retrospective cross-sectional case series, MRI images of 30 eyes from fifteen patients (age ≥ 60 years) with distance XT and no high myopia were compared with those of 14 eyes from seven YHP. Rectus muscle (RM) pulley positions relative to the globe center were assessed. The lateral rectus muscle–superior rectus (LR–SR) band was evaluated for rupture.
Results: Mean age of patients with XT was 73.7 ± 5.5 years. Compared with YHP, patients with XT showed significant inferior displacement of the lateral rectus (LR) pulley (–3.6 ± 1.2 mm vs. − 2.0 ± 1.1 mm, p < 0.01) and temporal displacement of the superior rectus (SR) pulley (–0.4 ± 1.2 mm vs. − 1.6 ± 0.8 mm, p < 0.01). No significant differences were observed in medial rectus or inferior rectus pulley positions. Inferior LR pulley displacement correlated with inferior SR pulley displacement (r = 0.41, p = 0.03), whereas no significant relationship was observed between LR pulley position and MR or IR pulley position. Rupture of the LR–SR band was observed in 24 orbits (80.0%).
Conclusion: Older Japanese adults with XT exhibit localized pulley displacement and LR–SR band rupture. These structural changes differ from the global sagging observed in sagging eye syndrome and may contribute to the pathogenesis of acquired exotropia in older adults. 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= END start-ver=1.4 cd-journal=joma no-vol=135 cd-vols= no-issue=4 article-no= start-page=747 end-page=759 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of cross-modal negative BOLD responses in the human sensory subcortex and cortex en-subtitle= kn-subtitle= en-abstract= kn-abstract=Functional magnetic resonance imaging (fMRI) is a noninvasive method for measuring human brain activity based on blood oxygenation level-dependent (BOLD) responses. Although many studies have reported positive BOLD responses evoked by sensory stimuli, others have reported negative BOLD responses (NBRs) in the sensory cortex when stimuli from different sensory modalities are presented (i.e., cross-modal NBRs). We conducted an fMRI experiment to better understand the characteristics of cross-modal NBRs in subcortical and cortical regions. Auditory and visual stimuli were presented unilaterally to one ear and to either the left or right visual field, respectively. The lateral geniculate nucleus and medial geniculate nucleus did not show a significant cross-modal NBR. In contrast, the primary auditory cortex showed a significant cross-modal NBR when visual stimuli were presented in either the contralateral or ipsilateral visual fields. Finally, we found that the cross-modal NBR in the early visual cortex was highly variable across subjects and did not exhibit consistent trends. However, each subject’s data exhibited considerable split-half reliability. Our results suggest that cross-modal NBR in the auditory cortex likely reflects mechanisms such as interhemispheric suppression, rather than those coordinated within the same hemisphere.
NEW & NOTEWORTHY This study demonstrated that the human primary auditory cortex showed a significant cross-modal negative BOLD response bilaterally, regardless of the visual field in which the visual stimuli were presented. This result suggests that the cross-modal negative BOLD response is not an epiphenomenon of visual cortex activation predominantly observed in the contralateral hemisphere, but is more likely to reflect interhemispheric suppression mechanisms. en-copyright= kn-copyright= en-aut-name=MiyataToshikazu en-aut-sei=Miyata en-aut-mei=Toshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukunagaMasaki en-aut-sei=Fukunaga en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LuoJunxiang en-aut-sei=Luo en-aut-mei=Junxiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoiIsao en-aut-sei=Yokoi en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoTetsuya en-aut-sei=Yamamoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiokaAyumi en-aut-sei=Yoshioka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoritaTomoyo en-aut-sei=Morita en-aut-mei=Tomoyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakemuraHiromasa en-aut-sei=Takemura en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Sensory and Cognitive Brain Mapping, Department of System Neuroscience, National Institute for Physiological Sciences kn-affil= affil-num=2 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=3 en-affil=Division of Sensory and Cognitive Brain Mapping, Department of System Neuroscience, National Institute for Physiological Sciences kn-affil= affil-num=4 en-affil=National Institute for Physiological Sciences kn-affil= affil-num=5 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=6 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Center for Information and Neural Networks (CiNet), Advanced ICT Research Institute, National Institute of Information and Communications Technology (NICT) kn-affil= affil-num=9 en-affil=Division of Sensory and Cognitive Brain Mapping, Department of System Neuroscience, National Institute for Physiological Sciences kn-affil= en-keyword=auditory system kn-keyword=auditory system en-keyword=cross-modal kn-keyword=cross-modal en-keyword=functional MRI kn-keyword=functional MRI en-keyword=visual system kn-keyword=visual system END start-ver=1.4 cd-journal=joma no-vol=330 cd-vols= no-issue=5 article-no= start-page=L593 end-page=L609 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The role of S100A8/A9 in the pathogenesis of acute exacerbations of pulmonary fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acute exacerbation of idiopathic pulmonary fibrosis is a life-threatening condition characterized by neutrophilic inflammation. S100A8/A9, an alarmin released by activated neutrophils and monocytes/macrophages, plays a pivotal role in regulating inflammatory responses. However, its specific involvement in acute exacerbations of pulmonary fibrosis remains unclear. This study evaluated the role of S100A8/A9 in the pathogenesis of acute exacerbations of pulmonary fibrosis. S100A8/A9 levels were measured in bronchoalveolar lavage fluid and serum from patients with idiopathic interstitial pneumonia, with and without acute exacerbations. To model acute exacerbations of pulmonary fibrosis, mice were intratracheally administered bleomycin followed by lipopolysaccharide. Subsequently, inflammatory cell infiltration, cytokine levels, morphological changes, and fibrosis marker levels in lung tissue and airways were analyzed. S100A8/A9 levels were significantly higher in the bronchoalveolar lavage fluid and serum of patients with idiopathic interstitial pneumonia experiencing acute exacerbations relative to those without; these levels were correlated with patient prognosis. In an experimental mouse model, intratracheal administration of bleomycin followed by lipopolysaccharide resulted in a significant increase in airway S100A8/A9 levels compared with bleomycin alone and control mice. Anti-S100A8/A9 neutralizing antibody Ab45 mitigated airway inflammation and lung fibrosis in mice with acute exacerbations of pulmonary fibrosis, reducing S100A8/A9 levels and neutrophil extracellular traps. In vitro, recombinant S100A8/A9 or lipopolysaccharide and neutrophils activated and differentiated fibroblasts; these effects were inhibited by anti-S100A8/A9 neutralizing antibody Ab45 and the humanized form of Ab45 (HuAb45). These findings highlight S100A8/A9 as a potential prognostic biomarker and therapeutic target for acute exacerbations of pulmonary fibrosis. en-copyright= kn-copyright= en-aut-name=NakamuraNaoki

We previously reported that EGFR tyrosine-kinase-inhibitor (TKI) induced CD8+ T-cell immunity, which was insufficient for tumor eradication. We evaluated the potential of combining EGFR-TKI with stimulator of interferon genes (STING) agonists in activating a systemic antitumor response. Using a syngeneic mouse model of genetically engineered Egfr-mutant NSCLC, we evaluated the antitumor effects of STING agonist ADU-S100, alone and combined with osimertinib. Immunohistochemistry and flow cytometry were used to assess the TME. Osimertinib alone enhanced CD8+ T-cell infiltration but not Natural Killer (NK) cell infiltration. ADU-S100 injection alone modestly suppressed tumor growth with increasing CD8+/NK cell infiltration in the TME, but lacked an abscopal effect. Combining ADU-S100 with osimertinib significantly enhanced the antitumor effects and CD8+/NK cell infiltration. Depletion of either CD8+ or NK cells reduced the combination effect. Crucially, the combination induced an abscopal effect accompanied by PD-1+/CD8+ cell infiltration. Combining osimertinib with a STING agonist augmented innate and adaptive immunity, inducing systemic antitumor responses in EGFR-mutant NSCLC. en-copyright= kn-copyright= en-aut-name=NishimuraJun

syndrome (MDS) remains poorly defined. Here, we generated a trisomy 8 mouse model by transferring a human chromosome 8 into murine embryonic stem cells and prospectively examined the effects on hematopoietic stem cells (HSC) by trisomy 8. The expression of inflammatory genes was enhanced, and hematopoietic programs mediated by transcription factors and polycomb repressive complex 2 (PRC2) were dysregulated in trisomy 8 HSC, which impaired their self-renewal and balanced differentiation. Trisomy 8 HSC altered the chromatin accessibility and conformations and activated Y chromosome genes, such as Uty/Kdm6c epigenetic modifier, which is known to demethylate histone H3K27me3 modification. The Uty gene facilitated the activation of PRC2-target and Runx1-target genes in leukemogenesis and drove the proliferation of human trisomy 8 leukemic cells. Since the RUNX1 gene is frequently mutated in patients with trisomy 8 MDS, its deletion attenuated the enhanced expression of inflammatory genes and mitigated the impaired self-renewal of trisomy 8 HSC in mice. Our findings reveal that trisomy 8 altered the transcriptional programs and chromatin conformations in HSC and drove a pre-malignant state through activating the expression of Uty, suggesting a route for the development of trisomy 8 MDS. en-copyright= kn-copyright= en-aut-name=BaiJie en-aut-sei=Bai en-aut-mei=Jie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ArakiKimi

kn-title=VGLL3 Regulates DAPK2-Mediated Autophagy During Osteoblast Differentiation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vestigial-like family member 3 (VGLL3), a transcriptional cofactor of the TEA domain family, has been previously identified as a regulator of osteoblast differentiation. Building upon our previous findings, we investigated VGLL3 function in MC3T3-E1 osteoblasts using an integrated approach combining transcriptomic analysis and functional assays to identify its downstream effectors and explore associated autophagy mechanisms. RNA-seq analysis of Vgll3-knockdown (shVgll3) cells identified death-associated protein kinase 2 (DAPK2), a regulator of autophagy, as a downstream effector. Autophagic activity was examined using transmission electron microscopy and western blot analysis of LC3-II and p62 proteins. The effects of Dapk2 knockdown (shDapk2) on osteoblast differentiation were evaluated using qPCR, western blotting, alkaline phosphatase staining, and Alizarin Red staining. Rapamycin treatment was used to determine whether pharmacologic activation of autophagy could restore osteoblast function. Vgll3 knockdown significantly suppressed autophagic flux, as evidenced by fewer autophagic vacuoles, decreased LC3-II accumulation, and increased p62 expression. A comparable reduction in autophagic activity was observed in shDapk2 cells and was accompanied by impaired osteoblast differentiation. Rapamycin treatment partially restored autophagy and osteogenic differentiation in Vgll3-deficient cells. Finally, overexpression of DAPK2 partially rescued autophagic activity and osteogenic differentiation in shVgll3 cells, supporting its role as a key downstream functional effector. FOXM1 was further implicated as a potential transcriptional regulator contributing to DAPK2 expression. Collectively, our findings suggest that VGLL3 may influence osteogenic differentiation in osteoblasts, potentially involving DAPK2-associated autophagy. en-copyright= kn-copyright= en-aut-name=HeYuhan en-aut-sei=He en-aut-mei=Yuhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=WengYao en-aut-sei=Weng en-aut-mei=Yao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SitosariHeriati en-aut-sei=Sitosari en-aut-mei=Heriati kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhengYilin en-aut-sei=Zheng en-aut-mei=Yilin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=QuYaxin en-aut-sei=Qu en-aut-mei=Yaxin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IkegameMika en-aut-sei=Ikegame en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamuraHirohiko en-aut-sei=Okamura en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Molecular Biology and Biochemistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Biology, Faculty of Dentistry, Universitas Gadjah Mada kn-affil= affil-num=5 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dental Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=autophagy kn-keyword=autophagy en-keyword=bone metabolism kn-keyword=bone metabolism en-keyword=death-associated protein kinase 2 kn-keyword=death-associated protein kinase 2 en-keyword=osteoblast differentiation kn-keyword=osteoblast differentiation en-keyword=vestigial-like 3 kn-keyword=vestigial-like 3 END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=e70666 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=Association between discoid lateral meniscus and medial meniscus posterior root tear: A retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Medial meniscus (MM) posterior root tear (PRT) has gained increasing attention because of its biomechanical impact and rapid progression to osteoarthritis. Identifying the risk factors for MMPRT is essential for early diagnosis. Although the discoid lateral meniscus (DLM) is a common congenital variant, no studies have reported on the relationship between MMPRT and DLM. This study aimed to examine the relationship between MMPRT and DLM.
Methods: This retrospective cohort study included 94 matched knees that underwent arthroscopic surgery between 2015 and 2021 (58 with MMPRT and 36 with other MM injuries). The matching was performed according to age and sex. Morphological analysis of the lateral meniscus (LM) was performed using coronal magnetic resonance imaging (MRI). DLM was defined as an LM ratio (LM width/tibial width) > 0.20. LM width, LM ratio and DLM prevalence were compared between the two groups. In the MMPRT group, subgroup analysis compared the preoperative and 1-year postoperative clinical outcomes between patients with and without DLM.
Results: The PRT group showed significantly greater LM width (12.6 ± 3.1 mm vs. 11.1 ± 2.2 mm; p = 0.03) and LM ratio (0.18 ± 0.04 vs. 0.16 ± 0.03; p = 0.01) compared with the other group. The incidence of DLM was also significantly higher in the PRT group (29.3% vs. 8.3%; p = 0.02). No significant differences in clinical scores were observed between the two subgroups either preoperatively or 1 year postoperatively. However, both groups demonstrated significant improvement in all clinical outcomes 1 year postoperatively (p < 0.01).
Conclusions: DLM was significantly more prevalent in patients with MMPRT than in those with other MM injuries. Favourable clinical outcomes were achieved following pullout repair in MMPRT knees regardless of the presence of DLM.
Level of Evidence: Level III, retrospective cohort study. en-copyright= kn-copyright= en-aut-name=YamashitaRyosuke en-aut-sei=Yamashita en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KoharaToshiki en-aut-sei=Kohara en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kochi Health Sciences Center 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, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= en-keyword=clinical outcome kn-keyword=clinical outcome en-keyword=discoid lateral meniscus kn-keyword=discoid lateral meniscus en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=morphology kn-keyword=morphology en-keyword=posterior root tear kn-keyword=posterior root tear END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=4963 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural insights into YheS-mediated release of SecM-arrested ribosome en-subtitle= kn-subtitle= en-abstract= kn-abstract=ATP-binding cassette subfamily F (ABCF) proteins interact with the ribosome to resolve translation defects near the peptidyl transferase center (PTC). In Escherichia coli, four ABCF proteins (EttA, Uup, YbiT, and YheS) selectively promote translation of distinct problematic nascent peptide sequences, but their molecular mechanisms remain unclear. Here, we present a 2.8 Å cryo-EM structure of the ribosome in complex with an ATPase-deficient mutant of YheS and investigate how it releases ribosomes arrested by the SecM nascent chain. YheS binds to the ribosomal E-site via the L1 stalk, and its P-site tRNA-interaction motif (PtIM) extends toward the PTC, displacing the CCA end of the P-site tRNA. Notably, the cryo-EM density corresponding to the SecM nascent chain within the exit tunnel is largely lost upon YheS binding. These observations suggest that YheS relieves peptide sequence-dependent stalling by perturbing nascent chain-tunnel interactions through P-site tRNA relocation. Steered molecular dynamics simulations provide qualitative support for this model. Together, our findings provide mechanistic insight into a mode of arrest release distinct from the translocon-mediated release mechanism. en-copyright= kn-copyright= en-aut-name=IsoKaishi en-aut-sei=Iso en-aut-mei=Kaishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaToma en-aut-sei=Ikeda en-aut-mei=Toma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamasakiKohei en-aut-sei=Yamasaki en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndoYushin en-aut-sei=Ando en-aut-mei=Yushin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SanoFumiya K. en-aut-sei=Sano en-aut-mei=Fumiya K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FurutaTadaomi en-aut-sei=Furuta en-aut-mei=Tadaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaguchiHideki en-aut-sei=Taguchi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NurekiOsamu en-aut-sei=Nureki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ChadaniYuhei en-aut-sei=Chadani en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ItohYuzuru en-aut-sei=Itoh en-aut-mei=Yuzuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=2 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=6 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=6 article-no= start-page=1053 end-page=1061 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=Two-dimensional metal–organic frameworks offer all-in-one cocatalysts for photocatalytic overall water splitting en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photocatalytic overall water splitting holds great promise for sustainable hydrogen production. For overall water splitting performed by one-step excitation, both the hydrogen evolution and oxygen evolution reactions are hindered kinetically; hence, it is necessary to employ site-selective modification of photocatalysts with hydrogen-evolving and oxygen-evolving cocatalysts. However, critical challenges remain, including the need for cumbersome, multi-step photodeposition processes and durable blocking layers to inhibit the reverse reactions. Here we find a conductive, two-dimensional metal–organic framework to serve as a simple, multifunctional cocatalyst. We loaded this framework on SrTiO3:Al, an overall water-splitting photocatalyst, using a one-step self-assembly method. The framework cocatalyst promoted steady photocatalysis with an apparent quantum efficiency of 31.5% at 350 nm, free from the reverse reaction even without blocking layers. We proposed the operational principles for the cocatalyst activity using spectroscopic, electrochemical and theoretical analyses. This two-dimensional metal–organic framework offers an all-in-one approach for designing efficient and practical one-step excitation overall water-splitting systems. en-copyright= kn-copyright=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: This study aimed to identify predictors of rapid recurrence following radical nephrectomy for non-metastatic renal cell carcinomas.
Patients and Methods: Patients with non-metastatic renal cell carcinoma who underwent radical nephrectomy between 2014 and 2024 at Okayama University Hospital were included. Rapid recurrence was defined as local or distant metastasis occurring within one year after radical nephrectomy, whereas recurrences occurring beyond one year were classified as non-rapid.
Results: Among a total of 194 patients, 37 (19%) experienced recurrence during a median follow-up of 37 months, with 16 (43%) being classified as experiencing rapid recurrence. The multivariate Cox hazard model revealed that microscopic venous invasion and a size of 60 mm or larger were predictors of rapid recurrence (hazard ratio=4.1, 95% confidence interval=1.5-11.4, p=0.006, and hazard ratio=8.0, 95% confidence interval=2.6-25.0, p<0.001, respectively). Dividing the entire cohort into four groups based on the presence of the two risk factors (0, 1: venous invasion, 1: tumor size, and 2), the median PFS was not estimable, 87, 67, and 7 months, respectively (p<0.001).
Conclusion: Microscopic venous invasion and tumor size of 60 mm or larger were identified as independent predictors of rapid recurrence following radical nephrectomy for non-metastatic renal cell carcinoma. en-copyright= kn-copyright= en-aut-name=BEKKUKENSUKE en-aut-sei=BEKKU en-aut-mei=KENSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 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=5 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=6 ORCID= en-aut-name=IWATATAKEHIRO en-aut-sei=IWATA en-aut-mei=TAKEHIRO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NISHIMURASHINGO en-aut-sei=NISHIMURA en-aut-mei=SHINGO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ARAKIMOTOO en-aut-sei=ARAKI en-aut-mei=MOTOO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Renal cell carcinoma kn-keyword=Renal cell carcinoma en-keyword=adjuvant therapy kn-keyword=adjuvant therapy en-keyword=radical nephrectomy kn-keyword=radical nephrectomy en-keyword=early recurrence kn-keyword=early recurrence en-keyword=metastases kn-keyword=metastases END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=17 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=Afatinib Overcomes Osimertinib Resistance via Egfr V804F Mutation in a Syngeneic Egfr-Mutant Lung Cancer Mouse Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osimertinib is the standard first-line treatment for advanced EGFR-mutant non-small cell lung cancer. However, acquired resistance invariably develops, and identifying novel resistance pathways is clinically important as a substantial portion remains undefined. We used an immunocompetent syngeneic lung cancer mouse model harboring an Egfr exon 19 deletion (mDEL tumors) to establish acquired resistance. Osimertinib-resistant tumors were generated in vivo using a drug-holiday/re-challenge protocol. The resistance mechanism was identified using Sanger sequencing, receptor tyrosine kinase arrays, and western blotting. Egfr V804F knock-in cells were generated using CRISPR/Cas9, and their sensitivity to osimertinib and afatinib was assessed in vitro and in vivo. We established two distinct osimertinib-resistant tumor lines in a syngeneic lung cancer mouse model (mDEL OsiR #1/#3). The analysis revealed an on-target secondary Egfr V804F mutation (corresponding to human EGFR V802F) in both tumor lines. Importantly, Egfr V804F knock-in cells demonstrated significant osimertinib resistance, with a 5.7–10.5-fold increase in in vitro IC50 (mean, 8.2-fold), but remained highly sensitive to afatinib. Furthermore, afatinib effectively overcame osimertinib resistance in the V804F knock-in cell-derived mouse model. Consistently, afatinib treatment resulted in marked tumor shrinkage and suppression of EGFR signaling in the established mDEL OsiR #1/#3 in vivo. These findings establish secondary Egfr V804F/EGFR V802F as an on-target osimertinib resistance mechanism, providing a preclinical rationale for evaluating afatinib in biomarker-selected patients harboring this alteration. en-copyright= kn-copyright= en-aut-name=TanakaTakaaki en-aut-sei=Tanaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

en-subject= kn-subject= en-title= kn-title=Lung Segmental Perfusion Defect Is Associated With Airway Complications After Living-Donor Lobar Lung Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=PURPOSE: Airway complications (ACs) are potentially fatal after lung transplantation (LT). Although bronchial blood flow to the graft is supplied mainly from the pulmonary circulation after LT, lung segmental perfusion defects (LSPDs) are occasionally identified on lung perfusion scintigraphy (Q-scinti) after living-donor lobar LT (LDLLT). Lung segmental perfusion defects may impair bronchial healing and contribute to the development of ACs. This study aimed to evaluate the relationship between LSPD and AC after LDLLT.
METHODS: We retrospectively reviewed 86 recipients who underwent LDLLT and 163 living donors at our institution from October 1998 to December 2023. Transplanted lungs that developed AC were classified as the AC group, whereas those without AC were classified as the non-AC group. Blood flow in the transplanted lungs was evaluated using Q-scinti after LDLLT.
RESULTS: AC developed in 8 (4.9%) of 163 transplanted lungs after LDLLT. Although there were no significant differences in recipient-related variables between the 2 groups, LSPD was detected significantly more frequently in the AC group (n = 8) than in the non-AC group (n = 155) (50.0% vs 6.5%, P = .002). Furthermore, transplanted lungs showing LSPD were associated with significantly higher grades of the pulmonary interlobar fissures at the time of living-donor lobectomy (P = .025). Overall survival did not differ between patients with and without AC after LDLLT.
CONCLUSIONS: LSPD on Q-scinti, which may develop in grafts with incomplete interlobar fissures during living-donor lobectomy, is associated with the development of AC after LDLLT.

This suggests that memory is modulated by neural networks containing clock neurons, although the underlying mechanisms remain unclear. In Drosophila melanogaster, approximately 240 clock neurons are grouped into at least eight distinct clusters. Among them, the dorsal–lateral neurons (LNds) are required for maintaining long-term memory (LTM). In contrast, the neuropeptide Pigment-dispersing factor (Pdf), expressed in both small and large ventral–lateral neurons (s-LNvs and l-LNvs, respectively), functions as a circadian output signal and is also essential for maintaining LTM. In addition, Pdf-expressing neurons (hereafter, Pdf neurons) release neurotransmitters other than Pdf, which are involved in LTM consolidation. However, the specific transmitters used by LNds and Pdf neurons in LTM processing have remained unknown. Here, we show that octopamine signaling from LNds is essential for LTM maintenance, whereas octopamine in Pdf neurons is essential for LTM consolidation. Temporally restricted knockdown of Tyramine β hydroxylase (Tbh), the gene encoding the enzyme required for octopamine synthesis, disrupted LTM maintenance when targeted in LNds, whereas it impaired LTM consolidation when targeted in Pdf neurons. Notably, Tbh knockdown in LNds or Pdf neurons had minimal effects on circadian behavioral rhythms or sleep. These findings reveal that octopamine released from specific subtypes of clock neurons independently regulates distinct phases of LTM in Drosophila. en-copyright= kn-copyright= en-aut-name=KurataYuto en-aut-sei=Kurata en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=SakaiTakaomi en-aut-sei=Sakai en-aut-mei=Takaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Biological Sciences, Tokyo Metropolitan 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=Department of Biological Sciences, Tokyo Metropolitan University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=11 article-no= start-page=4879 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rice Genotype-Dependent Phyllosphere Microbiome Assembly and Isolation of Antagonistic Burkholderia for Sheath Blight Biocontrol en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice sheath blight (RSB), caused by Rhizoctonia solani, causes 10–50% yield losses globally. Using 16S rRNA sequencing of 100 rice cultivars, we found that resistant varieties harbor significantly more diverse bacterial communities (3230 OTUs; 2064 unique) than susceptible cultivars (599 OTUs; 36 unique). Resistant varieties were enriched in beneficial Burkholderiaceae, Bacillaceae, and Pseudomonadaceae, while Sphingobacteriaceae and Enterobacteriaceae were predominant in the susceptible rice varieties. From the 260 bacterial isolates, Burkholderia vietnamiensis J14EPLEAF2 presented potent antifungal activity (77% inhibition), suppressed lesion development, and abolished sclerotia formation. This strain displayed multiple plant growth-promoting traits, enhanced seed germination, and primed defense responses by upregulating PR5 and PR10. Hypersensitive response assays confirmed B. vietnamiensis as non-pathogenic, unlike B. gladioli and B. cepacia. This study identifies B. vietnamiensis J14EPLEAF2 as a promising, safe biocontrol agent for sustainable rice disease management. en-copyright= kn-copyright= en-aut-name=Danso OforiAndrews en-aut-sei=Danso Ofori en-aut-mei=Andrews kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NasimiZohreh en-aut-sei=Nasimi en-aut-mei=Zohreh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AhmedMuhammad Irfan en-aut-sei=Ahmed en-aut-mei=Muhammad Irfan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanYaoting en-aut-sei=Yan en-aut-mei=Yaoting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiWang en-aut-sei=Li en-aut-mei=Wang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandroAbdul Ghani en-aut-sei=Kandro en-aut-mei=Abdul Ghani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaKazunori en-aut-sei=Okada en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= en-aut-name=ZhengAiping en-aut-sei=Zheng en-aut-mei=Aiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=2 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=3 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=4 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=5 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=6 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=7 en-affil=Agro-Biotechnology Research Center, The University of Tokyo kn-affil= affil-num=8 en-affil=Bioproductivity Informatics Research Team, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=9 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=10 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= en-keyword=rice phyllosphere kn-keyword=rice phyllosphere en-keyword=Rhizoctonia solani kn-keyword=Rhizoctonia solani en-keyword=sheath blight kn-keyword=sheath blight en-keyword=Burkholderia vietnamiensis kn-keyword=Burkholderia vietnamiensis en-keyword=biocontrol kn-keyword=biocontrol en-keyword=microbiome kn-keyword=microbiome en-keyword=16S rRNA sequencing kn-keyword=16S rRNA sequencing en-keyword=plant growth-promoting bacteria kn-keyword=plant growth-promoting bacteria en-keyword=disease resistance kn-keyword=disease resistance END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=11 article-no= start-page=4730 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Basis of Lifestyle Divergence in Rice-Associated Burkholderia: From Pathogenesis to Plant Growth Promotion en-subtitle= kn-subtitle= en-abstract= kn-abstract=The genus Burkholderia encompasses both plant pathogenic and beneficial species, yet the genomic determinants underlying this lifestyle divergence remain poorly understood. Using 16S rRNA sequencing of 100 rice cultivars, our companion study demonstrated that resistant varieties are enriched in beneficial Burkholderiaceae, leading to the isolation of three phenotypically contrasting strains. Here, we present comparative genomic analyses of non-pathogenic biocontrol strain Burkholderia vietnamiensis J14EpLeaf2 and pathogenic strains Burkholderia gladioli A1EpSeed5 and Burkholderia cepacia J14Eple. Pathogenic strains possess significantly larger genomes (8.36–8.46 Mb) enriched in mobile genetic elements compared to the streamlined 6.95 Mb genome of B. vietnamiensis. CAZyme analysis revealed broader repertoires of glycoside hydrolases and polysaccharide lyases in pathogens, consistent with enhanced plant cell wall degradation. B. gladioli possesses a complete T3SS and expanded T6SS with 301 predicted effectors, while B. cepacia lacks structural T3SS genes but harbors 271 candidate effectors predicted to be secreted via alternative secretion pathways, compared to 180 in B. vietnamiensis. Notably, B. cepacia harbors cystic fibrosis-associated markers (cable pili, ZmpA/ZmpB), raising significant biosafety concerns that preclude its agricultural application. LC-MS validated IAA, ornibactin, and AHL production in B. vietnamiensis, supporting its plant growth-promoting and biocontrol functions. Computational PPI networks predicted distinct interaction landscapes requiring experimental validation. This study provides a genomic framework for distinguishing pathogenic from beneficial Burkholderia and supports B. vietnamiensis as a safe biocontrol agent while cautioning against B. cepacia J14Eple. en-copyright= kn-copyright= en-aut-name=OforiAndrews Danso en-aut-sei=Ofori en-aut-mei=Andrews Danso kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NasimiZohreh en-aut-sei=Nasimi en-aut-mei=Zohreh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AckahFrank Kwekucher en-aut-sei=Ackah en-aut-mei=Frank Kwekucher kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AhmedMuhammad Irfan en-aut-sei=Ahmed en-aut-mei=Muhammad Irfan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanYaoting en-aut-sei=Yan en-aut-mei=Yaoting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LiWang en-aut-sei=Li en-aut-mei=Wang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KandroAbdul Ghani en-aut-sei=Kandro en-aut-mei=Abdul Ghani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkadaKazunori en-aut-sei=Okada en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= en-aut-name=ZhengAiping en-aut-sei=Zheng en-aut-mei=Aiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=2 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=3 en-affil=Department of Crop Science, School of Agriculture and Natural Sciences, University of Cape Coast kn-affil= affil-num=4 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=5 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=6 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=7 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= affil-num=8 en-affil=Agro-Biotechnology Research Center, The University of Tokyo kn-affil= affil-num=9 en-affil=Bioproductivity Informatics Research Team, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University kn-affil= en-keyword=Burkholderia kn-keyword=Burkholderia en-keyword=comparative genomics kn-keyword=comparative genomics en-keyword=virulence factors kn-keyword=virulence factors en-keyword=secretion systems kn-keyword=secretion systems en-keyword=CAZymes kn-keyword=CAZymes en-keyword=plant-microbe interactions kn-keyword=plant-microbe interactions en-keyword=biocontrol kn-keyword=biocontrol en-keyword=pathogenicity kn-keyword=pathogenicity en-keyword=protein–protein interaction networks kn-keyword=protein–protein interaction networks en-keyword=rice sheath blight kn-keyword=rice sheath blight END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=1756863 end-page=1756863 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260515 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Behavior of serum thyroglobulin in relation to thyroid function under low-thyrotropin conditions in general practice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Serum thyroglobulin (Tg) and thyroid hormones are essential biomarkers in the diagnosis and management of thyroid diseases. Although Tg is routinely measured as a marker for thyroid neoplasia and an adjunct in the diagnosis of thyrotoxicosis due to destructive thyroiditis, its clinical significance under conditions of abnormal thyroid function remains unclear.
Methods: We investigated the association between serum Tg levels and thyroid function in 292 patients who underwent simultaneous evaluation of serum Tg, free thyroxine (FT4), and free triiodothyronine (FT3) levels in routine clinical practice. Based on thyroid-stimulating hormone (TSH) levels, participants were classified into three groups: high-TSH (> 4.23 μIU/mL; n = 38), normal-TSH (0.61–4.23 μIU/mL; n = 191), and low-TSH (< 0.61 μIU/mL; n = 63).
Results: The low-TSH group exhibited significantly higher serum Tg levels (118.66 ± 32.13 ng/mL) than the normal-TSH (70.20 ± 23.48 ng/mL) and high-TSH (34.70 ± 13.62 ng/mL) groups. Among patients positive for TSH-receptor antibodies (TRAb) or thyroid-stimulating antibodies (TSAb), elevated Tg levels were observed exclusively in the low-TSH group. Correlation analyses revealed that Tg levels were positively correlated with the FT3/FT4 ratio in the low-TSH group (rho = 0.62, p < 0.01), and this association was more evident in patients positive for both TRAb and TSAb (rho = 0.71, p < 0.01). These associations remained significant after multivariable adjustment and were supported by correlations between Tg and SPINA-GD, a model-based index of thyroid function reflecting deiodinase activity, with similar findings observed in patients with autoimmune hyperthyroidism.
Conclusion: These findings suggest that serum Tg levels may reflect biochemical features consistent with T3 predominance in autoimmune hyperthyroidism and have potential clinical utility in characterizing disease pathophysiology. en-copyright= kn-copyright= en-aut-name=SazumiYosuke en-aut-sei=Sazumi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuyamaAtsuhito en-aut-sei=Suyama en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YasudaMiho en-aut-sei=Yasuda en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FurukawaMasanori en-aut-sei=Furukawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=FT3/FT4 ratio kn-keyword=FT3/FT4 ratio en-keyword=hyperthyroidism kn-keyword=hyperthyroidism en-keyword=iodothyronine deiodinase kn-keyword=iodothyronine deiodinase en-keyword=thyroglobulin kn-keyword=thyroglobulin en-keyword=TSH- receptor antibody kn-keyword=TSH- receptor antibody END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=102635 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=Epidemiological and molecular characteristics of human-biting ticks in areas endemic to Japanese spotted fever: a prospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tick-borne diseases (TBDs) have become a great health concern worldwide. This study aimed to clarify the pathogenic and potentially pathogenic microorganisms carried by ticks that bite humans and to assess the risk of acquiring tick-borne infections in regions endemic for Japanese spotted fever. Tick specimens were prospectively collected from patients who presented with tick bites at 10 medical institutions in the Hiroshima, Okayama, and Kagawa prefectures, Japan between May 2023 and December 2024. The evaluated parameters included the estimated bite location, date of bite, patient age, tick species identification, and presence of TBD-associated pathogens in the collected ticks. Overall, 191 ticks were collected from 181 patients. Among patients with known sex, females were slightly more prevalent than males, and 45.9% of the patients were aged ≥ 70 years. Seasonal distribution demonstrated a peak incidence from April to July, with the highest number of cases observed in June (29.3%). Amblyomma testudinarium was the predominant species, accounting for 152 (79.6%) ticks, followed by Haemaphysalis hystricis (7.3%) and Haemaphysalis longicornis (6.8%). Nymphs represented the majority (83.8%), whereas adults and larvae accounted for 14.6% and 1.0%, respectively. A total of 27 ticks (14.1%) carried Rickettsia species, including two identified species (Rickettsia tamurae and Rickettsia monacensis) and one unclassified Rickettsia species. However, molecular analysis did not detect any known human pathogenic organisms, including Ehrlichia and Anaplasma species, Francisella tularensis, or Rickettsia japonica. Further epidemiological data regarding the abundance of tick-borne pathogens will provide valuable surveillance information with significant clinical utility for disease diagnosis and management. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SunamiHiroshi en-aut-sei=Sunami en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamotoKenta en-aut-sei=Nakamoto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HidaniYoshimi en-aut-sei=Hidani en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KidaKouji en-aut-sei=Kida en-aut-mei=Kouji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsurumiGo en-aut-sei=Tsurumi en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Sumiyoshi Fujii 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 General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Numakuma Hospital kn-affil= affil-num=7 en-affil=Okayama Prefectural Institute for Environmental Science and Public Health kn-affil= affil-num=8 en-affil=Okayama Prefectural Institute for Environmental Science and Public Health kn-affil= affil-num=9 en-affil= kn-affil= en-keyword=Epidemiology kn-keyword=Epidemiology en-keyword=Japanese spotted fever kn-keyword=Japanese spotted fever en-keyword=Rickettsia species kn-keyword=Rickettsia species en-keyword=Tick bite kn-keyword=Tick bite en-keyword=Tick-borne disease kn-keyword=Tick-borne disease END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=5 article-no= start-page=4118 end-page=4121 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Arterial Reconstruction of the Left Gastric Artery Supplying the Replaced Left Hepatic Artery in Distal Pancreatectomy with Celiac Axis Resection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Distal pancreatectomy with celiac axis resection (DP-CAR) with reconstruction of the left gastric artery (LGA) is a technically challenging procedure. The middle colic artery is commonly used for LGA reconstruction. This study highlights our novel arterial reconstruction of the LGA using the common hepatic artery (CHA) supplying the replaced left hepatic artery (rLHA) during DP-CAR.
Patient and Methods. A 65-year-old man diagnosed with locally advanced unresectable pancreatic body cancer underwent DP-CAR following systemic chemotherapy. As a rLHA arising from the LGA was present, arterial reconstruction was necessary.
Results. After confirming resectability, the CHA and LGA were encircled. Following division of the pancreas and radical lymphadenectomy, the origin of the celiac axis (CA) was divided. Subsequently, the CHA and LGA were transected and anastomosed. An indocyanine green fluorescence system was used to confirm adequate arterial blood supply and satisfactory tissue perfusion. Operative time was 215 min, with an estimated blood loss of 35 mL.
Conclusions. This study demonstrated a novel arterial reconstruction of the LGA supplying the rLHA during DP-CAR. The CHA may be a candidate for the reconstruction of the LGA in DP-CAR. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoAtene en-aut-sei=Ito en-aut-mei=Atene kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokoyamaShohei en-aut-sei=Yokoyama en-aut-mei=Shohei 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, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Distal pancreatectomy with celiac axis resection kn-keyword=Distal pancreatectomy with celiac axis resection en-keyword=Arterial reconstruction kn-keyword=Arterial reconstruction en-keyword=Pancreatic cancer kn-keyword=Pancreatic cancer END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue=1 article-no= start-page=97 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260424 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Navigating long-term patient-reported outcomes after colorectal cancer surgery in older adults: ostomy, nutritional status, and living conditions as determinants in a prospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To elucidate determinants of long-term patient-reported outcomes (PROs) following colorectal cancer (CRC) surgery in older adults, focusing on the impact of ostomy creation, nutritional status, and living conditions on functional independence and quality of life (QoL).
Methods This single-center, prospective observational study included patients aged ≥ 75 years who underwent elective CRC resection between July 2020 and December 2023. Comprehensive geriatric assessments were performed preoperatively, and PROs—including Instrumental Activities of Daily Living (IADL), EQ-5D, and EQ-VAS—were reassessed more than one year postoperatively. The primary outcomes were postoperative changes in IADL and QoL. Modified Poisson regression identified independent determinants of long-term decline in each PRO domain.
Results Sixty patients (median age 79 years; 60% female) completed one-year follow-up. IADL declined in 35.6% of patients, EQ-5D in 26.6%, and EQ-VAS in 43.3%. Multivariate analysis revealed that stoma formation was independently associated with IADL decline (adjusted RR = 3.37, 95% CI 1.50–7.54, p = 0.003), whereas living alone postoperatively correlated with preserved IADL (adjusted RR = 0.14, 95% CI 0.02–0.87, p = 0.035). Low preoperative BMI (< 20 kg/m2) was significantly associated with EQ-5D deterioration (adjusted RR = 5.25, 95% CI 1.20–22.94, p = 0.027). No significant predictors were identified for EQ-VAS decline.
Conclusion Among older CRC patients, stoma creation predicts long-term functional decline, while low BMI predicts QoL deterioration. Conversely, independent living appears protective for functional maintenance. Integrating PROs into perioperative assessment and tailoring surgical, nutritional, and social interventions may enhance survivorship outcomes in this aging population. en-copyright= kn-copyright= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItagakiShiori en-aut-sei=Itagaki en-aut-mei=Shiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraRie en-aut-sei=Tamura en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaYoshikazu en-aut-sei=Matsuoka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Perioperative Management Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= affil-num=4 en-affil=Perioperative Management Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Perioperative Management Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= en-keyword=Colorectal cancer kn-keyword=Colorectal cancer en-keyword=Older patients kn-keyword=Older patients en-keyword=Patient-reported outcomes kn-keyword=Patient-reported outcomes en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Surgery kn-keyword=Surgery END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=7 article-no= start-page=1181 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Predictive Nomogram for Recurrence After Upfront Surgery for Resectable Pancreatic Ductal Adenocarcinoma: A Multicenter Study (OS-HBP-2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Postoperative recurrence is a critical issue in the treatment of resectable pancreatic ductal adenocarcinoma (rPDAC). Moreover, the prognosis after early recurrence is extremely poor. This study aimed to develop a recurrence prediction model and to define early recurrence after upfront surgery (UFS) for rPDAC. Methods: This multicenter retrospective study included patients who underwent UFS for anatomically rPDAC between January 2013 and December 2017. Multivariate analyses were conducted to identify the risk factors for recurrence-free survival and to construct a recurrence prediction model. Subsequently, a minimum p value approach was used to determine the optimal cutoff values for early and late recurrence. Results: The cohort included 603 patients (325 men and 278 women). During the median follow-up period of 25 months (interquartile range, 15–38 months), 381 patients (63.2%) experienced a recurrence. Multivariate analyses revealed carbohydrate antigen 19-9 ≥37 U/mL (hazard ratio [HR], 1.58; p < 0.001), tumor size ≥ 2.2 cm (HR, 1.59; p < 0.001), lymph node metastasis (HR, 1.86; p < 0.001), R1 resection (HR, 1.56; p = 0.002), and no adjuvant chemotherapy (HR, 1.54; p < 0.001) as independent predictors. The recurrence prediction model demonstrated an area under the curve of 0.72–0.75. The optimal threshold for early and late recurrences was a recurrence-free interval of five months. Carbohydrate antigen 19-9 ≥ 156 U/mL was a significant predictor of early recurrence (OR, 3.28; p < 0.001). Conclusions: This study identified the prognostic risk factors for recurrence and developed a recurrence prediction model for patients undergoing UFS for rPDAC. Moreover, a recurrence-free interval of five months was identified as the optimal threshold for distinguishing between early and late recurrences. en-copyright= kn-copyright= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiokiMasayoshi en-aut-sei=Hioki en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KojimaToru en-aut-sei=Kojima en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NobuokaDaisuke en-aut-sei=Nobuoka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuiKenta en-aut-sei=Sui en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=InagakiMasaru en-aut-sei=Inagaki en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShinouraSusumu en-aut-sei=Shinoura en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KimuraMasashi en-aut-sei=Kimura en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsudaTatsuo en-aut-sei=Matsuda en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AokiHideki en-aut-sei=Aoki en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Himeji Red Cross Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, Kagawa Prefectural Hospital kn-affil= affil-num=10 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=11 en-affil=Department of Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=12 en-affil=Department of Surgery, Matsuyama Shimin Hospital kn-affil= affil-num=13 en-affil=Department of Surgery, Tenwakai Matsuda Hospital kn-affil= affil-num=14 en-affil=Department of Surgery, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=15 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=pancreatic cancer kn-keyword=pancreatic cancer en-keyword=resectable kn-keyword=resectable en-keyword=upfront surgery kn-keyword=upfront surgery en-keyword=recurrence kn-keyword=recurrence en-keyword=nomogram kn-keyword=nomogram END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=4 article-no= start-page=602 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcomes After Robot-Assisted Versus Open Pancreatoduodenectomy: A Propensity Score-Matching Analysis in a High-Volume Center (TAKUMI-7) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Although the safety and feasibility of robot-assisted pancreatoduodenectomy (RPD) compared to open pancreatoduodenectomy (OPD) have been reported, studies investigating the advantages of RPD remain limited. Moreover, only a few studies have investigated the effects of robotic surgery on textbook outcomes (TO). Methods: This single-center retrospective study included 400 patients who underwent RPD and OPD at our institution between January 2017 and December 2025. Outcomes were compared between the RPD (n = 162) and OPD (n = 238) groups using propensity score-matching (PSM) analysis. The factors associated with TO were examined. Results: Before PSM, significant differences were observed between the groups. PSM yielded RPD (n = 117) and OPD (n = 117) with equal preoperative factors. The RPD group demonstrated a significantly shorter operative time (402 vs. 444 min, p < 0.001), lesser blood loss (75 vs. 270 mL, p < 0.001), shorter postoperative hospital stays (13 vs. 22 days, p < 0.001), and fewer major complications (17.1 vs. 44.4%, p < 0.001), resulting in a higher TO achievement rate (76.9 vs. 52.1%, p = 0.001). Adjusted multivariate analyses identified robotic surgery (odds ratio 3.04, p < 0.001) as an independent predictor of TO. Conclusions: This study demonstrated that RPD was potentially superior to OPD in terms of short-term outcomes. Robotic surgery was significantly associated with TO after pancreatoduodenectomy at the expert’s hand. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoAtene en-aut-sei=Ito en-aut-mei=Atene kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaNaohiro en-aut-sei=Okada en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YokoyamaShohei en-aut-sei=Yokoyama en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hepatobiliary Pancreatic Surgery, Ehime University Graduate School of Medicine 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= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=pancreatoduodenectomy kn-keyword=pancreatoduodenectomy en-keyword=robotic surgery kn-keyword=robotic surgery en-keyword=open surgery kn-keyword=open surgery en-keyword=textbook outcome kn-keyword=textbook outcome END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=1 article-no= start-page=349 end-page=354 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=Modified Subtraction Technique for the Middle Hepatic Vein Tributary and Glissonean Pedicle in Right Lobe Graft Procurement en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: The procurement of right lobe grafts while preserving the middle hepatic vein (MHV) tributaries (V5 and V8) just before graft retrieval is technically challenging. Moreover, the safe isolation of the hepatic duct from the Glissonean pedicle is essential in living donor hepatectomy. To date, few studies have reported surgical techniques for preserving the MHV tributaries during right lobe graft procurement.
Patients and Methods: This report presents our modified subtraction technique for managing the MHV tributaries and Glissonean pedicle during right lobe graft procurement. First, a subtraction technique for the MHV tributaries was initiated by isolating the right Glissonean pedicle. The lower tip of the tape was placed behind the caudate lobe and passed behind the right hepatic vein. Each end of the tape was then passed behind V5 and V8, followed by dissection of the remaining liver parenchyma between them. Subsequently, a subtraction technique for the Glissonean pedicle was applied to safely isolate the right hepatic duct and hilar plate.
Results: Between September 2011 and May 2025, seven donors underwent right lobe graft procurement using the subtraction technique for the middle hepatic vein tributaries. The mean operative time was 381 min with an estimated blood loss of 217 ml. Using the subtraction technique, all middle hepatic vein tributaries were preserved just before graft retrieval.
Conclusion: This study presents subtraction techniques used during living donor hepatectomy. The technique may facilitate liver parenchyma dissection while preserving MHV tributaries just before graft retrieval and isolating the Glissonean pedicle. en-copyright= kn-copyright= en-aut-name=TAKAGIKOSEI en-aut-sei=TAKAGI en-aut-mei=KOSEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FUJITOMOKAZU en-aut-sei=FUJI en-aut-mei=TOMOKAZU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YASUIKAZUYA en-aut-sei=YASUI en-aut-mei=KAZUYA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NISHIYAMATAKEYOSHI en-aut-sei=NISHIYAMA en-aut-mei=TAKEYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NAGAIYASUO en-aut-sei=NAGAI en-aut-mei=YASUO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YOKOYAMASHOHEI en-aut-sei=YOKOYAMA en-aut-mei=SHOHEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UMEDAYUZO en-aut-sei=UMEDA en-aut-mei=YUZO 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 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 Hepatobiliary Pancreatic Surgery, Ehime University Graduate School of Medicine 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=Subtraction kn-keyword=Subtraction en-keyword=tape repositioning kn-keyword=tape repositioning en-keyword=middle hepatic vein kn-keyword=middle hepatic vein en-keyword=donor procurement kn-keyword=donor procurement END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=3 article-no= start-page=1570 end-page=1576 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Donor Cirrhosis Outcome Risk Estimator (CORE) Score on Recipient Outcomes Following Living-donor Liver Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Several studies have investigated predictive factors for outcomes of living-donor liver transplantation (LDLT). However, few have examined the clinical significance of the Cirrhosis Outcome Risk Estimator (CORE) score on prognosis following LDLT. This study aimed to investigate the impact of donor CORE scores in predicting the outcomes of patients undergoing LDLT.
Patients and Methods: This single-center retrospective study included 362 adult LDLT recipients at our Institution between January 1998 and December 2024. Patient and graft survival rates were compared between the groups with low (≤0.05) and high (>0.05) CORE scores. Subsequently, multivariate analyses were performed to investigate prognostic factors for survival, including the CORE score.
Results: Patients in the group with a low CORE score had significantly better survival (p=0.001; 5-year, 85.3% vs. 76.2%) and graft survival (p=0.001; 5-year, 84.1% vs. 74.6%) than those with a high CORE score. Multivariate analyses identified the CORE score (>0.05) as an independent predictor of patient survival (hazard ratio=1.70, 95% confidence interval=1.01-2.62, p=0.018) and graft survival (hazard ratio=1.66, 95% confidence interval=1.07-2.57, p=0.024).
Conclusion: This study demonstrated the clinical significance of donor CORE scores in recipient outcomes after LDLT. Assessment of the donor CORE score may be useful for evaluating the quality of liver grafts and estimating recipient outcomes. en-copyright= kn-copyright= en-aut-name=TAKAGIKOSEI en-aut-sei=TAKAGI en-aut-mei=KOSEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FUJITOMOKAZU en-aut-sei=FUJI en-aut-mei=TOMOKAZU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YASUIKAZUYA en-aut-sei=YASUI en-aut-mei=KAZUYA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NISHIYAMATAKEYOSHI en-aut-sei=NISHIYAMA en-aut-mei=TAKEYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NAGAIYASUO en-aut-sei=NAGAI en-aut-mei=YASUO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OKADANAOHIRO en-aut-sei=OKADA en-aut-mei=NAOHIRO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YOKOYAMASHOHEI en-aut-sei=YOKOYAMA en-aut-mei=SHOHEI 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 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=Living-donor liver transplantation kn-keyword=Living-donor liver transplantation en-keyword=donor kn-keyword=donor en-keyword=recipient kn-keyword=recipient en-keyword=survival outcomes kn-keyword=survival outcomes en-keyword=Cirrhosis Outcome Risk Estimator score kn-keyword=Cirrhosis Outcome Risk Estimator score en-keyword=CORE kn-keyword=CORE END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=22 article-no= start-page=3694 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognosis Prediction Model After Upfront Surgery for Resectable Pancreatic Ductal Adenocarcinoma: A Multicenter Study (OS-HBP-2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Upfront surgery (UFS) remains the standard treatment for patients with resectable pancreatic ductal adenocarcinoma (PDAC). We aimed to investigate the prognostic factors for survival after UFS in patients with resectable PDAC and to develop a prognostic prediction model. Methods: This multicenter, retrospective study included 603 patients who underwent UFS for resectable PDAC between January 2013 and December 2017. Univariate and multivariate analyses were performed to identify prognostic factors for overall survival (OS). We constructed a prognostic prediction model for OS after UFS. An internal validation was performed to evaluate the discriminative performance of the model. Results: The 1-, 3-, and 5-year OS rates were 83.7%, 48.2%, and 37.5%, respectively. The Cox proportional hazards model showed that tumor size > 2 cm (hazard ratio [HR] 1.50, p = 0.001); tumor contact with the portal and superior mesenteric veins of ≤180° (HR 1.47, p = 0.003); carbohydrate antigen 19-9 levels of 40 to 500 U/mL (HR 1.59, p = 0.002) and ≥500 U/mL (HR 2.16, p < 0.001); and a modified Glasgow Prognostic Score of two (HR 1.56, p = 0.038) were predictors associated with OS. The prognostic prediction model for 5-year OS demonstrated an area under the curve of 0.68. The calibration plots indicate a concordance index of 0.63. Conclusions: We identified the preoperative prognostic factors for OS and developed a prognostic prediction model to estimate OS in patients undergoing UFS for resectable PDAC. Our model may be useful and internally validated for predicting OS. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiokiMasayoshi en-aut-sei=Hioki en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KojimaToru en-aut-sei=Kojima en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NobuokaDaisuke en-aut-sei=Nobuoka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuiKenta en-aut-sei=Sui en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=InagakiMasaru en-aut-sei=Inagaki en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShinouraSusumu en-aut-sei=Shinoura en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KimuraMasashi en-aut-sei=Kimura en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsudaTatsuo en-aut-sei=Matsuda en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AokiHideki en-aut-sei=Aoki en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Himeji Red Cross Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, Kagawa Prefectural Hospital kn-affil= affil-num=10 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=11 en-affil=Department of Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=12 en-affil=Department of Surgery, Matsuyama Shimin Hospital kn-affil= affil-num=13 en-affil=Department of Surgery, Tenwakai Matsuda Hospital kn-affil= affil-num=14 en-affil=Department of Surgery, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=15 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=pancreatic cancer kn-keyword=pancreatic cancer en-keyword=resectable kn-keyword=resectable en-keyword=upfront Surgery kn-keyword=upfront Surgery en-keyword=outcomes kn-keyword=outcomes END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=11 article-no= start-page=801 end-page=809 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors and Strategies for Failure to Rescue Following Hepatectomy: A Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Failure to rescue (FTR), defined as mortality after major postoperative complications, is a crucial indicator of surgical quality. Although mortality rates after hepatectomy have declined owing to improved surgical techniques and perioperative care, FTR remains a major concern. This review synthesizes the current evidence on the risk factors contributing to FTR after hepatectomy and explores multidisciplinary strategies to reduce its rate. Post-hepatectomy liver failure, hemorrhage, bile leakage, and sepsis commonly precede FTR. Risk factors for FTR are multifactorial and include patient-, procedure-, and system-related factors. Higher procedural volumes are associated with lower FTR rates, likely due to better infrastructure, experienced personnel, and access to rapid interventions. Strategies to reduce the FTR rate include preoperative optimization, intraoperative precision, and vigilant postoperative surveillance. System-level approaches, such as multidisciplinary rounds, standardized escalation protocols, and a robust institutional safety culture, are also pivotal. Future innovations, such as predictive analytics, artificial intelligence, and wearable monitoring devices, offer considerable potential for the early detection of complications. Centralization of complex liver surgeries to high-volume centers is recommended to enhance team preparedness. This review emphasizes the importance of adopting a comprehensive, proactive, and technologically integrated approach to reduce the FTR rate after hepatectomy and improve patient survival. en-copyright= kn-copyright= en-aut-name=KimuraJiro en-aut-sei=Kimura en-aut-mei=Jiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=failure to rescue kn-keyword=failure to rescue en-keyword=hepatectomy kn-keyword=hepatectomy en-keyword=mortality kn-keyword=mortality en-keyword=risk factor kn-keyword=risk factor END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=18 article-no= start-page=3038 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250917 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcomes of Robotic Pancreatectomy in the Octogenarian: A Multicenter Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Due to the increasing incidence of pancreatic and periampullary cancers with advancing age, coupled with the growing evidence supporting minimally invasive pancreatectomy, the demand for such procedures is rising. However, data on the feasibility of robotic pancreatectomy in octogenarian patients remain scant. This study aimed to investigate overall outcomes of robotic pancreatectomy and evaluate its safety and feasibility in octogenarian patients. Methods: A multicenter, retrospective study was conducted, including 380 patients who underwent robotic pancreatectomy at two high-volume centers in Japan from April 2020 to December 2024. Using prospectively collected data, we compared outcomes between younger patients (<80 years) and octogenarian patients (≥80 years). Multivariable logistic regression analyses were performed to assess the impact of age on postoperative outcomes. Results: Among the 380 patients, with a median age of 72 (interquartile range: 61–77) years, 213 underwent robotic pancreatoduodenectomy (RPD), and 167 underwent robotic distal pancreatectomy (RDP). Octogenarian patients were found to have more comorbidities and a higher incidence of malignant diseases. Octogenarians experienced significantly longer hospital stays post-RPD (22 [octogenarian; n = 36] vs. 14 [younger; n = 177] days, p < 0.001) and post-RDP (14 [n = 23] vs. 10.5 [n = 144] days, p = 0.02), yet their perioperative outcomes were comparable. Multivariable analyses indicated that age (≥80 years) was not a significant risk factor for major complications following robotic pancreatectomy (odds ratio, 1.33; 95% confidence interval, 0.59–2.84; p = 0.479). Conclusions: This multicenter study conducted at high-volume centers suggests that robotic pancreatectomy can be safely performed in carefully selected octogenarian patients. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaYuichiro en-aut-sei=Uchida en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaharaTakeshi en-aut-sei=Takahara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UyamaIchiro en-aut-sei=Uyama en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SudaKoichi en-aut-sei=Suda en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil= Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil= Department of Surgery, Fujita Health University kn-affil= affil-num=3 en-affil= Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil= Department of Surgery, Fujita Health University kn-affil= affil-num=5 en-affil= Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil= Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil= Department of Advanced Laparoscopic and Robotic Surgery, Fujita Health University kn-affil= affil-num=8 en-affil= Department of Surgery, Fujita Health University kn-affil= affil-num=9 en-affil= Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=robotic pancreatectomy kn-keyword=robotic pancreatectomy en-keyword=pancreatoduodenectomy kn-keyword=pancreatoduodenectomy en-keyword=distal pancreatectomy kn-keyword=distal pancreatectomy en-keyword=elderly patients kn-keyword=elderly patients END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=7 article-no= start-page=6296 end-page=6305 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=Association of Preoperative Inspiratory Muscle Weakness and Respiratory Sarcopenia with Postoperative Pneumonia Following Esophagectomy: A Multicenter Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Esophagectomy is associated with a high rate of postoperative pneumonia, which significantly impacts patient outcomes, including survival and quality of life. While some modifiable risk factors have been identified, the specific role of preoperative respiratory muscle function remains to be fully elucidated. Therefore, this study was designed to investigate the association of preoperative inspiratory muscle weakness (IMW) and respiratory sarcopenia (RS) with postoperative pneumonia in patients with esophageal cancer who underwent esophagectomy.
Methods Patients with esophageal cancer who underwent esophagectomy between July 2021 and June 2023 were enrolled in this multicenter, retrospective, cohort study. The primary outcome was postoperative pneumonia, while preoperative IMW and RS were the main exposures. Respiratory sarcopenia was defined as the presence of both IMW and low skeletal muscle mass, which is assessed by using bioelectrical impedance analysis. Associations were analyzed by using G-computation within a Bayesian framework.
Results A total of 213 patients were enrolled in this study. Postoperative pneumonia occurred in 42 patients (19.7%). Preoperative IMW was strongly associated with an increased risk of pneumonia, with a mean risk difference (RD) of 18.1% (95% credible interval [CrI] 5–33.6). The posterior probability that the RD exceeds 5% was > 98%. Respiratory sarcopenia also showed a potential association, although with greater uncertainty (mean RD, 11.2%; 95% CrI − 3.8 to 27.9). The posterior probability that the RD exceeds 5% was 76.7%.
Conclusions Preoperative IMW is a notable risk factor for postoperative pneumonia following esophagectomy. While a potential link with RS was found, its role remains uncertain and requires further investigation. en-copyright= kn-copyright= en-aut-name=OkuraKazuki en-aut-sei=Okura en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoHiroki en-aut-sei=Sato en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatayamaSho en-aut-sei=Katayama en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYusuke en-aut-sei=Takahashi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagakiYushi en-aut-sei=Nagaki en-aut-mei=Yushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WakitaAkiyuki en-aut-sei=Wakita en-aut-mei=Akiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraYoshinori en-aut-sei=Fujiwara en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SatoYusuke en-aut-sei=Sato en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KasukawaYuji en-aut-sei=Kasukawa en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Akita University Hospital kn-affil= affil-num=2 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Rehabilitation, Kawasaki University of Medical Welfare kn-affil= affil-num=4 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Rehabilitation Medicine, Akita University Hospital kn-affil= affil-num=6 en-affil=Department of Esophageal Surgery, Akita University Hospital kn-affil= affil-num=7 en-affil=Department of Esophageal Surgery, Akita University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Digestive Surgery, Kawasaki Medical School kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Esophageal Surgery, Akita University Hospital kn-affil= affil-num=13 en-affil=Department of Rehabilitation Medicine, Akita University Hospital kn-affil= affil-num=14 en-affil=Department of Rehabilitation Medicine, Akita University Hospital kn-affil= en-keyword=Inspiratory muscle kn-keyword=Inspiratory muscle en-keyword=Respiratory sarcopenia kn-keyword=Respiratory sarcopenia en-keyword=Postoperative pneumonia kn-keyword=Postoperative pneumonia en-keyword=Perioperative rehabilitation kn-keyword=Perioperative rehabilitation en-keyword=Esophagectomy kn-keyword=Esophagectomy en-keyword=Esophageal cancer kn-keyword=Esophageal cancer END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=13 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=Atezolizumab + Chemotherapy in Older Patients With Lung Cancer in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pivotal phase 3 trials leading to the approvals of atezolizumab─chemotherapy combinations for non-small cell and extensive-stage small cell lung cancer (NSCLC and ES-SCLC) had strict eligibility criteria. J-TAIL-2 was a prospective, observational study in Japan that evaluated atezolizumab regimens for advanced NSCLC/ES-SCLC, including patients ineligible for global trials. The primary endpoint was 12-month overall survival (OS); safety and efficacy in subgroups defined by age, ECOG PS and/or G8 score, and creatinine clearance were key secondary endpoints. As of February 3, 2023, 1217 patients were treated in clinical practice based on Japanese labeling/treatment guidelines. Patients received atezolizumab with either carboplatin and nab-paclitaxel (atezo + CnP), carboplatin/cisplatin and pemetrexed (atezo + PP), or bevacizumab and carboplatin and paclitaxel (atezo + bev + CP) in the NSCLC cohort (n = 814) or with carboplatin and etoposide (atezo + CE) in the ES-SCLC cohort (n = 403). Overall, 53.5% were ≥ 70 years old, and 11.8% had ECOG PS ≥ 2; median G8 scores were 13 (NSCLC cohort) and 12 (ES-SCLC). Patients < 70 and ≥ 70 years had similar median (m)OS and progression-free survival (mPFS) across treatment regimens. Patients with ECOG PS < 2 and G8 score ≥ median had the highest mOS/PFS vs. patients with ECOG PS ≥ 2 and G8 score 0.5 log2 fold change) and linked to clinical outcomes reported in J-TAIL-2. IL-6, MUC-16, and KRT-19 were associated with shorter progression-free survival across multiple regimens. Granzyme A and B, immune activation markers, were elevated in responders who received atezolizumab + CnP and atezolizumab + bev + CP. High levels of baseline immune stimulation proteins were associated with irAEs across regimens. Protein expression changes were varied and regimen-dependent in subgroup analyses including older patients and those with EGFR-mutant tumors. These data warrant further investigation across different cancer types and atezolizumab-containing regimens to determine their relevance to efficacy and irAE occurrence of atezolizumab combination therapy. en-copyright= kn-copyright= en-aut-name=GotoYasushi en-aut-sei=Goto en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishioMakoto en-aut-sei=Nishio

motility can serve as an early indicator of reproductive effects caused by environmental chemicals or genetic perturbations. However, sperm motility is highly sensitive to external factors such as osmolarity, ionic composition, and the timing of measurement after activation, making it challenging to obtain consistent and reproducible measurements. Here, we present a standardized protocol for assessing sperm motility in Japanese medaka (Oryzias latipes) using a sperm motility analysis system (SMAS), an application for computer-aided sperm motility analysis (CASA). This protocol details the procedures for sperm collection, activation, and quantitative motility assessment, with particular focus on changes in the percentage of motile sperm post activation and the effects of sperm cryopreservation. We demonstrate time-dependent declines in sperm motility and velocity, and highlight the importance of early post-activation measurements to accurately capture peak motility. Notably, cryopreservation significantly accelerated the decline in sperm motility rate without affecting the initial proportion of motile sperm. To enable reliable comparisons among experimental groups, we recommend standardizing the initiation time after sperm activation by using CASA, and show that measurements should be initiated within 1 min after activation to obtain consistent and reliable data. This standardized SMAS-based protocol provides a robust and reproducible framework for sperm motility analysis in medaka and will be valuable not only for studies in reproductive biology, toxicology, and environmental risk assessment but also for applied research, such as breeding of aquacultural fishes. en-copyright= kn-copyright= en-aut-name=KuroyanagiMiwa en-aut-sei=Kuroyanagi en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKeigo en-aut-sei=Okamoto en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatoAi en-aut-sei=Kato en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamazakiTouko en-aut-sei=Yamazaki en-aut-mei=Touko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KameiYasuhiro en-aut-sei=Kamei en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeEiji en-aut-sei=Watanabe en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaruseKiyoshi en-aut-sei=Naruse en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OginoYukiko en-aut-sei=Ogino en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Advanced Aquaculture Science, Faculty of Marine Bioscience and Technology, Fukui Prefectural University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Aquatic Molecular Developmental Biology, Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= affil-num=4 en-affil=Interuniversity Bio-Backup Project Center, National Institute for Basic Biology (NIBB) kn-affil= affil-num=5 en-affil=Laboratory of Bioresources, National Institutes of Natural Sciences kn-affil= affil-num=6 en-affil=Optics and Bioimaging Facility, NIBB kn-affil= affil-num=7 en-affil=Basic Biology Program, Graduate University for Advanced Studies (SOKENDAI) kn-affil= affil-num=8 en-affil=Laboratory of Bioresources, National Institutes of Natural Sciences kn-affil= affil-num=9 en-affil=Laboratory of Aquatic Molecular Developmental Biology, Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= en-keyword=computer-aided sperm motility analysis (CASA) kn-keyword=computer-aided sperm motility analysis (CASA) en-keyword=medaka kn-keyword=medaka en-keyword=sperm motility kn-keyword=sperm motility en-keyword=sperm motility analysis system (SMAS) kn-keyword=sperm motility analysis system (SMAS) END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=6 article-no= start-page=e72814 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CPPD-Induced Iliopsoas Bursitis Mimicking Pyomyositis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcium pyrophosphate deposition disease may mimic an iliopsoas abscess on imaging.

Insulin-like growth factor (IGF)-I, a major mediator of growth hormones, plays an important role in metabolism, neuroprotection, and systemic homeostasis, and therefore may be useful in predicting the severity and prognosis of LC. Methods: This study included patients who visited a specialized clinic for long COVID between 2022 and 2025 during the Omicron period and had serum IGF-I measurements taken. IGF-I levels were expressed as age- and sex-adjusted standard deviation scores (IGF-I SD), and patients were classified into low (SD < −1.0), normal (−1.0 ≤ SD < 1.0), and high (SD ≥ 1.0) groups. Clinical characteristics, patient-reported outcomes, laboratory data, and follow-up duration were analyzed. Results: A total of 811 patients were included (median 42 years; 52.5% female). Compared with the normal group, the low-IGF-I group exhibited higher fatigue (FAS: 37.0 vs. 34.0; p < 0.05) and depressive (SDS: 50.0 vs. 49.0; p < 0.05) status. Multivariable linear regression analyses identified lower IGF-I SD as independently associated with higher scores of both FAS and SDS. IGF-I SD values showed negative correlations with ferritin (ρ = −0.125, p < 0.05) and TSH (ρ = −0.202, p < 0.01) and positive correlations with albumin (ρ = 0.227, p < 0.01) and FT4 (ρ = 0.165, p < 0.01). Among the 237 patients who completed follow-up, the median duration from the initial visit to recovery tended to be longer in the low-IGF-I group (221 days) compared with the normal (191 days) and high (109 days) groups, although these differences were not statistically significant overall. In patients aged < 50 years, the low-IGF-I group showed a relatively longer follow-up duration (p < 0.05). Furthermore, the low-IGF-I group had a longer time to recovery compared to the high-IGF-I group (p < 0.05), and this difference was more pronounced in patients under 50 years of age, with significant differences observed among the three IGF-I groups. Conclusions: Lower IGF-I levels in LC may be associated with greater fatigue and depressive symptoms and longer recovery time, particularly in younger patients. Further studies are needed to clarify the clinical significance of these findings. en-copyright= kn-copyright= en-aut-name=SuyamaAtsuhito en-aut-sei=Suyama en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=fatigue kn-keyword=fatigue en-keyword=IGF-I kn-keyword=IGF-I en-keyword=long COVID kn-keyword=long COVID en-keyword=recovery kn-keyword=recovery END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=1774957 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hochuekkito attenuates anxiety-like behavior associated with pulmonary inflammation induced by intratracheal lipopolysaccharides in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: We have previously demonstrated that intratracheal lipopolysaccharide (LPS) injection induces significant pulmonary inflammation accompanied by hippocampal microglial activation, indicative of neuroinflammation. Hochuekkito (HET) is a traditional Japanese herbal medicine used to treat various conditions, including mental disorders and physical weakness. We have previously reported that HET ameliorates anxiety-like behaviors induced by intraperitoneal LPS injections in mice. However, its anxiolytic effects on anxiety-like behaviors due to pulmonary inflammation remain poorly understood. Therefore, in the present study, we aimed to investigate the effects of HET on anxiety-like behaviors induced by intratracheal LPS injection in mice.
Methods: Mice received HET (1.0 g/kg) once daily for 2 weeks through oral gavage prior to LPS treatment. The light-dark box test was conducted 24 h following LPS injection to assess anxiety-like behaviors. Diazepam, a clinically used anxiolytic, served as a positive control. The lung wet-to-dry weight ratio was determined, and the concentrations of interleukin-6 (IL-6) in the lungs and serum were assessed.
Results: Repeated administration of HET prevented the development of anxiety-like behaviors and reduced serum IL-6 concentrations and hippocampal Il6 mRNA expression levels in LPS-treated mice. Diazepam failed to exert significant effects in LPS-treated mice, whereas HET remained effective under inflammatory conditions. Moreover, LPS injections significantly increased the number of Iba-1-immunoreactive microglial cells in the CA1 region of the hippocampus, whereas this effect was suppressed by treatment with HET. In the bronchoalveolar lavage fluid (BALF), the LPS-induced increase in white blood cell count was significantly reduced by treatment with HET. Furthermore, HET alleviated LPS-induced pulmonary inflammation, as evidenced by decreased lung wet-to-dry weight ratios.
Conclusion: This study suggests that inflammation induced by intratracheal LPS injection contributes to anxiety-like behaviors in mice and that IL-6 may play a key role in linking peripheral inflammation to neuroinflammatory responses. The anxiolytic effects of HET appear to be associated, at least in part, with the suppression of IL-6 elevation in both the periphery and the hippocampus, along with attenuation of microglial activation. Our findings suggest that HET may serve as a potential therapeutic agent for anxiety-like behaviors associated with pulmonary inflammation. en-copyright= kn-copyright= en-aut-name=IzushiYasuhisa en-aut-sei=Izushi en-aut-mei=Yasuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaTeppei en-aut-sei=Ueda en-aut-mei=Teppei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TasakaYuichi en-aut-sei=Tasaka en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitamuraYoshihisa en-aut-sei=Kitamura en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pharmacotherapy, Graduate School of Pharmacy, Shujitsu University kn-affil= affil-num=2 en-affil=Department of Pharmaceutical Sciences for Health Crisis Management, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=3 en-affil=Department of Pharmacotherapy, Graduate School of Pharmacy, Shujitsu University kn-affil= affil-num=4 en-affil=Laboratory of Clinical Pharmacy, School of Pharmacy, Shujitsu University kn-affil= affil-num=5 en-affil=Department of Medical Neurobiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Medical Neurobiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pharmacotherapy, Graduate School of Pharmacy, Shujitsu University kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=hochuekkito kn-keyword=hochuekkito en-keyword=inflammation kn-keyword=inflammation en-keyword=interleukin-6 kn-keyword=interleukin-6 en-keyword=lipopolysaccharide kn-keyword=lipopolysaccharide en-keyword=lung kn-keyword=lung en-keyword=traditional Japanese herbal medicine kn-keyword=traditional Japanese herbal medicine END start-ver=1.4 cd-journal=joma no-vol=195 cd-vols= no-issue= article-no= start-page=110231 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=Biliverdin supplementation in perfusate and preservation solution attenuates ischemia-reperfusion injury in a rat donation-after-circulatory-death heart transplantation model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Heart transplantation faces a persistent donor shortage; therefore, hearts from donation after circulatory death have become a feasible option despite unavoidable warm ischemia and subsequent ischemia-reperfusion injury. Biliverdin, an endogenous bile pigment with strong antioxidant and anti-inflammatory properties, has shown protective effects against ischemia-reperfusion injury in several organ transplantation models. Whether biliverdin attenuates warm ischemic injury in donation after circulatory death heart transplantation remains unclear. This study evaluated biliverdin supplementation in the perfusate and preservation solution in a rat donation after circulatory death model.
Methods: Circulatory death was induced under deep anesthesia, and warm ischemia was maintained for 18 minutes, including the mandatory 5-minute stand-off period. Donor hearts were then flushed and subsequently cold-stored in the same biliverdin-supplemented extracellular-type trehalose–containing Kyoto solution, whereas control grafts received extracellular-type trehalose–containing Kyoto without biliverdin at both stages before heterotopic transplantation. Grafts were assessed at 3 and 24 hours after reperfusion (n = 6 per group). Evaluations included early graft recovery, myocardial injury markers, histological and ultrastructural changes, and inflammatory and stress-response gene expression.
Results: Biliverdin significantly improved early graft recovery, shortening reanimation time and increasing left ventricular fractional shortening at 24 hours. Serum troponin I levels were lower in biliverdin-treated grafts. Biliverdin also reduced histological injury and inflammatory cell infiltration. Ultrastructural analysis showed preserved mitochondrial architecture and ultrastructural integrity. Early proinflammatory gene expression was suppressed.
Conclusion: Biliverdin supplementation in the perfusate and preservation solution attenuates ischemia-reperfusion injury in the experimental rat donation after circulatory death heart transplantation model. These findings provide proof of concept for further mechanistic and translational evaluation of biliverdin for myocardial protection in donation after circulatory death. en-copyright= kn-copyright= en-aut-name=TokiokaKohei en-aut-sei=Tokioka en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HirayamaTakahiro en-aut-sei=Hirayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IgawaTakuro en-aut-sei=Igawa en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AokageToshiyuki en-aut-sei=Aokage en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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=11 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=12 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Biological Process of Aging, Tokyo Metropolitan Institute for Geriatrics and Gerontology kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=20260603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Classification of hypotony maculopathy based on optical coherence tomography findings and risk factors for visual outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To classify hypotony maculopathy (HM) using optical coherence tomography (OCT) findings and to investigate the associations among morphological types, clinical factors, and visual outcomes.
Methods We retrospectively reviewed 60 eyes that developed HM after trabeculectomy. HM was classified according to the distribution and configuration of chorioretinal undulations on OCT B-scans. Between-group comparisons were performed, and factors associated with the morphological classification and logMAR best-corrected visual acuity (BCVA) at 3 months after HM onset (3-month BCVA) were determined.
Results HM was classified into three OCT-based types by categorizing chorioretinal undulations as folds (U-shaped troughs) or spikes (V-shaped troughs): Type 1, folds only on vertical scans; Type 2, folds on both vertical and horizontal scans; Type 3, folds on both scans, with spikes. Axial length in Type 3 was significantly longer than that in Type 2 (P = 0.034). Subfoveal choroidal thickness was significantly thinner in Type 3 than in Types 1 and 2 (both P < 0.001). Minimum intraocular pressure (IOP) was significantly higher in Type 1 than in Types 2 and 3 (P < 0.001 and P = 0.003, respectively), with no difference between Types 2 and 3. In multivariable analysis using Type 1 as the reference group, minimum IOP was significantly associated with Type 2 (P = 0.001). For Type 3, both minimum IOP (P = 0.03) and subfoveal choroidal thickness (P = 0.02) showed significant associations. The 3-month BCVA was significantly worse in Type 3 than in Types 1 and 2 (P < 0.001 and P = 0.007, respectively). Chorioretinal spikes and preoperative BCVA were significantly associated with 3-month BCVA (both P < 0.001). Exploratory receiver operating characteristic analysis assessed the discriminative ability of subfoveal choroidal thickness for the presence of chorioretinal spikes (AUC = 0.876). A thickness of 195.0 μm was identified as a candidate cutoff value (sensitivity 92.3% and specificity 72.3%).
Conclusions In HM following TLE, chorioretinal spikes and preoperative BCVA are significantly associated with the 3-month BCVA. In HM, a thin subfoveal choroid (< 195.0 μm), may be associated with chorioretinal spikes, suggesting the need for careful postoperative IOP and OCT monitoring. en-copyright= kn-copyright= en-aut-name=KanzakiYuki en-aut-sei=Kanzaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraMiyuki en-aut-sei=Fujiwara en-aut-mei=Miyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiwaraRie en-aut-sei=Fujiwara en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkamotoSara en-aut-sei=Okamoto en-aut-mei=Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitsuiNaruka en-aut-sei=Mitsui en-aut-mei=Naruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HosokawaMio Morizane en-aut-sei=Hosokawa en-aut-mei=Mio Morizane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HayashiJunko en-aut-sei=Hayashi en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MasudaYuki en-aut-sei=Masuda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkatsukaRiku en-aut-sei=Akatsuka en-aut-mei=Riku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TsujiAkihiro en-aut-sei=Tsuji en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Hypotony maculopathy kn-keyword=Hypotony maculopathy en-keyword=Optical coherence tomography kn-keyword=Optical coherence tomography en-keyword=Trabeculectomy kn-keyword=Trabeculectomy en-keyword=Chorioretinal spike kn-keyword=Chorioretinal spike en-keyword=Choroidal thickness kn-keyword=Choroidal thickness en-keyword=Visual outcomes kn-keyword=Visual outcomes END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=3 article-no= start-page=104848 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=Predictors of therapeutic response and pain after near-infrared photoimmunotherapy in head and neck cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Near-infrared photoimmunotherapy (NIR-PIT) has been approved by the Japanese national health insurance for approximately five years, and clinical experience has steadily accumulated. However, reports analyzing treatment outcomes and pain-related factors remain limited. This study aimed to identify predictors of therapeutic response and pain following NIR-PIT.
Methods: This retrospective cohort study included 25 patients who underwent NIR-PIT for head and neck cancer between January 2021 and June 2025. Lesion diameter and thickness were evaluated in relation to complete response (CR), and the frequency and predictors of post-treatment pain were assessed.
Results: Among 22 evaluable patients, eight achieved CR. Lesions with a shorter longest diameter and thinner thickness were significantly associated with higher CR rates (p = 0.011 and p = 0.024). Moderate-to-severe pain (Numerical Rating Scale ≥4) occurred in 18 of 48 treatment cycles (37.5%) but was significantly less frequent in patients with a history of reconstructive surgery (p = 0.017).
Conclusions: NIR-PIT demonstrated particularly favorable efficacy for short, thin lesions, suggesting that early introduction of treatment may be associated with improved therapeutic outcomes. A history of reconstructive surgery was associated with reduced post-treatment pain, highlighting the importance of individualized treatment and pain management strategies in head and neck cancer patients undergoing NIR-PIT. en-copyright= kn-copyright= en-aut-name=MatsumotoJunya en-aut-sei=Matsumoto en-aut-mei=Junya 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=Near-infrared photoimmunotherapy kn-keyword=Near-infrared photoimmunotherapy en-keyword=Head and neck cancer kn-keyword=Head and neck cancer en-keyword=Treatment response kn-keyword=Treatment response en-keyword=Tumor size kn-keyword=Tumor size en-keyword=Tumor thickness kn-keyword=Tumor thickness en-keyword=Pain kn-keyword=Pain END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=5 article-no= start-page=e70494 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=Comparative Efficacy of First-Line Immune Checkpoint Inhibitor-Based Combination Therapies in Patients With Sarcomatoid Renal Cell Carcinoma: A Japanese Multicenter Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Sarcomatoid renal cell carcinoma (sRCC) is an aggressive histological variant associated with a poor prognosis. While immune checkpoint inhibitor (ICI)-based combinations have become the standard of care, the optimal first-line regimen, specifically dual immunotherapy (IO-IO) vs. IO plus tyrosine kinase inhibitor (IO-TKI), remains controversial. We herein examined the real-world clinical outcomes of Japanese patients with sRCC.
Methods: We conducted a retrospective multicenter study on 46 patients with advanced or metastatic sRCC receiving first-line ICI-based combination therapy between January 2018 and December 2024 (IO-IO: n = 18; IO-TKI: n = 28). In a comparative survival analysis, three favorable-risk patients in the IO-TKI group were excluded to align risk profiles, focusing on intermediate/poor-risk groups (n = 43). The primary endpoint was overall survival (OS).
Results: In the entire cohort (n = 46), the objective response rate was numerically higher in the IO-TKI group (64.3%) than in the IO-IO group (50.0%) (p = 0.37). In the comparative analysis of intermediate/poor-risk patients (n = 43), progression-free survival (PFS) was slightly longer (p = 0.071), and OS was significantly longer (p = 0.016) in the IO-TKI group than in the IO-IO group. A multivariable analysis adjusted for IMDC risk categories showed favorable survival with the IO-TKI regimen (HR 0.37, p = 0.061).
Conclusions: The present study indicates that first-line IO-TKI combination therapy represents a promising treatment option with a potential survival advantage over IO-IO therapy for Japanese patients with sRCC. However, due to the retrospective design and small sample size, reliably determining the comparative efficacy of these regimens remains challenging, and further validation is warranted. en-copyright= kn-copyright= en-aut-name=TamuraKeita en-aut-sei=Tamura en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsushitaYuto en-aut-sei=Matsushita en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeHiromitsu en-aut-sei=Watanabe en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanagisawaTakafumi en-aut-sei=Yanagisawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriKeiichiro en-aut-sei=Mori en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorinakaHirofumi en-aut-sei=Morinaka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=ToyodaShingo en-aut-sei=Toyoda en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NukayaTakuhisa en-aut-sei=Nukaya en-aut-mei=Takuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaenosonoRyoichi en-aut-sei=Maenosono en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KomuraKazumasa en-aut-sei=Komura en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujitaKazutoshi en-aut-sei=Fujita en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TakaharaKiyoshi en-aut-sei=Takahara en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=AzumaHaruhito en-aut-sei=Azuma en-aut-mei=Haruhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=InamotoTeruo en-aut-sei=Inamoto en-aut-mei=Teruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Urology, Hamamatsu University School of Medicine kn-affil= affil-num=2 en-affil=Department of Urology, Hamamatsu University School of Medicine kn-affil= affil-num=3 en-affil=Department of Urology, Hamamatsu University School of Medicine kn-affil= affil-num=4 en-affil=Department of Urology, Jikei University School of Medicine kn-affil= affil-num=5 en-affil=Department of Urology, Jikei University School of Medicine kn-affil= affil-num=6 en-affil=Department of Urology, Kawasaki Medical School 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, Kindai University Faculty of Medicine kn-affil= affil-num=9 en-affil=Department of Urology, Fujita-Health University School of Medicine kn-affil= affil-num=10 en-affil=Department of Urology, Osaka Medical and Pharmaceutical University kn-affil= affil-num=11 en-affil=Department of Urology, Kawasaki Medical School 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, Kindai University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Urology, Fujita-Health University School of Medicine kn-affil= affil-num=15 en-affil=Department of Urology, Osaka Medical and Pharmaceutical University kn-affil= affil-num=16 en-affil=Department of Urology, Hamamatsu University School of Medicine kn-affil= en-keyword=dual immunotherapy kn-keyword=dual immunotherapy en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=immunotherapy plus tyrosine kinase inhibitor kn-keyword=immunotherapy plus tyrosine kinase inhibitor en-keyword=sarcomatoid renal cell carcinoma kn-keyword=sarcomatoid renal cell carcinoma END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=6 article-no= start-page=BSR20260010 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=Tubulogenesis of bovine uterine glands by epidermal growth factor and collagen I in 3D culture systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Uterine glands are endometrial exocrine epithelia that support early embryo development. Their secretions are particularly essential for conceptus elongation in cattle. Uterine glands develop from the luminal epithelium and elongate into the stromal layer toward the myometrium. This process is regulated by growth factors, WNT proteins, and the surrounding extracellular matrix (ECM); however, the precise mechanisms that govern bovine uterine gland morphogenesis remain unclear. In this study, we determined how these signaling factors and ECM components affect the tubular formation of bovine uterine gland fragments in 3D culture systems. Uterine gland fragments were enzymatically isolated from bovine endometria and 3D-cultured in Matrigel with or without growth factors (EGF, FGF1, FGF2, FGF7, FGF10, and IGF-1) and WNT (WNT3A, WNT5A, and WNT7A) proteins. Of these, only EGF stimulated the elongation of uterine gland fragments and eventually induced the formation of uterine gland-like structures. EGF-induced tubulogenesis was accompanied by a rapid increase in cell proliferation and alterations in cell–ECM interactions. The supplementation of collagen I with Matrigel further promoted the elongation of the tubular structures. Although the addition of collagen I did not alter the gene expression profiles of the uterine gland-like structures, the integrin-ROCK pathway contributed to the collagen-induced enhancement of elongation. Our findings clarified that EGF and collagen I, but not FGFs, IGF-1, or WNTs, are key regulators for the tubular formation of 3D-cultured bovine uterine gland fragments. This 3D culture system provides a new platform to examine the cellular and molecular mechanisms underlying bovine uterine gland morphogenesis. en-copyright= kn-copyright= en-aut-name=SuginoYosuke en-aut-sei=Sugino en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaRei en-aut-sei=Ichikawa en-aut-mei=Rei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuyamaShuichi en-aut-sei=Matsuyama en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoKohei en-aut-sei=Kawano en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji 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 Bioagricultural Sciences, Nagoya University kn-affil= affil-num=3 en-affil=Graduate School of Bioagricultural Sciences, Nagoya University kn-affil= affil-num=4 en-affil=Department of Veterinary Medicine, Tokyo University of Agriculture and Technology 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=3D cell culture kn-keyword=3D cell culture en-keyword=bovine, collagen I kn-keyword=bovine, collagen I en-keyword=epidermal growth factor kn-keyword=epidermal growth factor en-keyword=tubular structure kn-keyword=tubular structure en-keyword=uterine gland kn-keyword=uterine gland END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260426 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=What Is the Pterygomandibular Raphe? A Confluence of Fasciae Rather Than a Discrete Structure en-subtitle= kn-subtitle= en-abstract= kn-abstract=The pterygomandibular raphe (PMR) has traditionally been described as a fibrous or tendinous band connecting the bucinator (BM) and superior pharyngeal constrictor (SPCM) muscles. However, recent evidence has questioned its existence. This study aimed to reevaluate the anatomy of the pterygomandibular region by preserving fascial continuity and examining the relationships among adjacent muscles and connective tissues. Twenty-five sides from formalin-fixed cadaveric heads were examined. Twenty sides underwent macroscopic dissection under a surgical microscope, and five sides were sectioned axially and analyzed histologically using Masson's trichrome staining to assess muscle–fascia continuity. The buccopharyngeal fascia (BpF) adhered tightly to the posterolateral surface of the BM. A ligament-like bundle observed between the BM and medial pterygoid muscle corresponded to an artificial continuation of the BpF created by dissection. Axial sections revealed that the BpF, masseteric, and temporalis fasciae converged anteriorly on the lateral surface of the BM, while posteriorly, the BpF and temporalis fascia also merged, forming a confluence of fasciae. No discrete tendinous or ligamentous PMR was identified. The so-called PMR represents a dissection artifact rather than a true anatomical structure. These findings emphasize the importance of preserving fascial relationships and using precise terminology in anatomical and clinical contexts. en-copyright= kn-copyright= en-aut-name=IwanagaJoe en-aut-sei=Iwanaga en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamaShion en-aut-sei=Hama en-aut-mei=Shion kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukinoKeiko en-aut-sei=Fukino en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KikutaShogo en-aut-sei=Kikuta en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HurMi‐Sun en-aut-sei=Hur en-aut-mei=Mi‐Sun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=CespedesMaria Cristina Manzanares en-aut-sei=Cespedes en-aut-mei=Maria Cristina Manzanares kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhyamaYoshio en-aut-sei=Ohyama en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkashiMasaya en-aut-sei=Akashi en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KomuneNoritaka en-aut-sei=Komune en-aut-mei=Noritaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KamochiHideaki en-aut-sei=Kamochi en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Tulane Center for Clinical Neurosciences, Tulane University School of Medicine kn-affil= affil-num=2 en-affil=Section of Oral and Maxillofacial Oncology, Division of Maxillofacial Diagnostic and Surgical Sciences, Faculty of Dental Science, Kyushu University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Anatomy, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University kn-affil= affil-num=4 en-affil=Dental and Oral Medical Center, Kurume University School of Medicine kn-affil= affil-num=5 en-affil=Department of Anatomy, Daegu Catholic University School of Medicine kn-affil= affil-num=6 en-affil=Human Anatomy and Embryology Unit.

A 10-year-old boy who fell from a skateboard was diagnosed with a tibial insertion avulsion fracture of the ACL and was treated arthroscopically. The avulsed fragment was provisionally fixed with guide pins inserted into its four corners, and the lateral view was checked to avoid penetration of the growth plate. Two ultrahigh-molecular-weight polyethylene tapes were passed through the ACL just above its tibial insertion, pulled through the four-corner bone tunnels in an X-shaped configuration, and tightened. The patient was immobilized for 3 weeks, and partial weight bearing was initiated at 4 weeks. Bone union was confirmed at 6 months using plain radiographs, and second-look arthroscopy and implant removal were performed 8 months postoperatively. During arthroscopy, complete union with smooth continuity of the articular cartilage at the fracture site and a stable ACL were observed. The patient had a full knee range of motion and no pain at the final follow-up. en-copyright= kn-copyright= en-aut-name=KoharaToshiki en-aut-sei=Kohara en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=MiyazawaShinichi en-aut-sei=Miyazawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 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=7 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=8 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=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery , NHO Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery , Japanese Red Cross Okayama Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery , Okayama University Graduate School of Medicine , Dentistry , and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=73466 end-page=73478 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=Construction of a Lightweight Simulation Environment Based on Topological Mapping en-subtitle= kn-subtitle= en-abstract= kn-abstract=Autonomous mobile robots require safe and efficient environmental representations for traversability-aware navigation and learning. In particular, self-learning of traversability from real-world driving experience can require robots to operate near the limits of their mobility, which introduces physical risks such as falls, malfunctions, or hardware damage. To provide a safer complementary environment for such validation and future learning, this paper proposes ATC-Mesh. This framework constructs a lightweight, simulation-ready mesh environment from the topological map produced by Adaptive Resonance Theory-based Topological Clustering with Different Topologies (ATC-DT) using high-density LiDAR point clouds. Unlike standard mesh reconstruction methods that directly process dense point clouds, ATC-Mesh generates a compact mesh from the node–edge structure of the topological map while preserving traversability attributes associated with the topological map. Experiments using two real-world LiDAR datasets show that ATC-Mesh achieves competitive mesh-construction quality compared with standard baseline methods while reducing construction time and mesh size. Gazebo experiments further show that the generated meshes can support waypoint-based navigation with a low simulation load. en-copyright= kn-copyright= en-aut-name=KatoYukinaga en-aut-sei=Kato en-aut-mei=Yukinaga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TodaYuichiro en-aut-sei=Toda en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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=Autonomous mobile robot kn-keyword=Autonomous mobile robot en-keyword=topological map kn-keyword=topological map en-keyword=digital twin kn-keyword=digital twin END start-ver=1.4 cd-journal=joma no-vol=194 cd-vols= no-issue= article-no= start-page=118923 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elucidation of mechanisms underlying the therapeutic effects of cordycepin on pulmonary hypertension, with a focus on cell senescence and gut microbiota en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Pulmonary hypertension (PH) is a progressive cardiopulmonary disorder characterized by excessive pulmonary vascular remodeling and aberrant proliferation of pulmonary artery smooth muscle cells (PASMCs). Emerging evidence suggests that gut microbiota dysbiosis contributes to PH development. Cordycepin, a natural adenosine analogue derived from Cordyceps militaris, has demonstrated antiproliferative and microbiota-modulating properties; however, its mechanism of action in PH remains unclear.
Objective: Elucidate the mechanisms underlying the therapeutic effects of cordycepin on PH, focusing on cellular senescence and gut microbiota.
Methods: The effects of cordycepin on PH pathology were investigated by transcriptome analysis of PASMCs from patients, and metagenomic analysis of rodent PH models. Cellular senescence was analyzed in lung tissue from p16Ink4a-CreERT2 reporter mice and in rat bone marrow-derived macrophages (BMDMs).
Results: RNA sequencing analysis revealed activation of p53 signaling by cordycepin in PASMCs. Cordycepin suppressed CDK1 expression and TERT phosphorylation at threonine 249. It ameliorated vascular and cardiac remodeling in PH rat and mouse models. Cordycepin induced M1-like macrophage senescence in p16 Ink4a reporter mice lungs and rat BMDMs. Cordycepin significantly reshaped the gut microbiota, increasing beneficial genera (e.g. Alistipes and Acetatifactor) and reducing proinflammatory taxa (e.g., Ruminococcus), with modulating key metabolic pathways, including short-chain fatty acid, tryptophan, and vitamin K2 metabolism.
Conclusion: Cordycepin exerts multi-target therapeutic effects in PH by inhibiting PASMC proliferation via the p53–CDK1/pTERT axis, modulating gut microbiota-linked immunometabolism and induces proinflammatory macrophage senescence. These findings support cordycepin as a promising candidate for PH therapies targeting the vascular, immune, and gut–lung axes. en-copyright= kn-copyright= en-aut-name=LiGaopeng en-aut-sei=Li en-aut-mei=Gaopeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhaoZhixin en-aut-sei=Zhao en-aut-mei=Zhixin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MachitaniMitsuhiro en-aut-sei=Machitani en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikawaRyou en-aut-sei=Ishikawa en-aut-mei=Ryou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshikawaKaori en-aut-sei=Ishikawa en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokotaNaoya en-aut-sei=Yokota en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HabaReiji en-aut-sei=Haba en-aut-mei=Reiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SunZhihong en-aut-sei=Sun en-aut-mei=Zhihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KuraharaLin-Hai en-aut-sei=Kurahara en-aut-mei=Lin-Hai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HiranoKatsuya en-aut-sei=Hirano en-aut-mei=Katsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Inner Mongolia Key Laboratory of Dairy Biotechnology and Engineering, Key Laboratory of Dairy Products Processing, Ministry of Agriculture and Rural Affairs, Key Laboratory of Dairy Biotechnology and Engineering, Ministry of Education, Inner Mongolia Agricultural University kn-affil= affil-num=3 en-affil=Division of Cancer Stem Cell, National Cancer Center Research Institute kn-affil= affil-num=4 en-affil=Department of Diagnostic Pathology, Kagawa University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Kagawa University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery, Faculty of Medicine, Kagawa University kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kagawa University Hospital kn-affil= affil-num=8 en-affil=Center for Advanced Heart Failure, Okayama University Hospital kn-affil= affil-num=9 en-affil=Inner Mongolia Key Laboratory of Dairy Biotechnology and Engineering, Key Laboratory of Dairy Products Processing, Ministry of Agriculture and Rural Affairs, Key Laboratory of Dairy Biotechnology and Engineering, Ministry of Education, Inner Mongolia Agricultural University kn-affil= affil-num=10 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Kagawa University kn-affil= affil-num=11 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Kagawa University kn-affil= en-keyword=Pulmonary hypertension kn-keyword=Pulmonary hypertension en-keyword=p53 kn-keyword=p53 en-keyword=CDK1 kn-keyword=CDK1 en-keyword=TERT kn-keyword=TERT en-keyword=p16 kn-keyword=p16 en-keyword=Microbiota kn-keyword=Microbiota END start-ver=1.4 cd-journal=joma no-vol=183 cd-vols= no-issue= article-no= start-page=156163 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=Photochemical oxidative synthesis of carboxylic acids from aldehydes or alcohols with water via CH bromination en-subtitle= kn-subtitle= en-abstract= kn-abstract=The photoinduced oxidation of aldehydes or alcohols with water to give the corresponding carboxylic acids is described.

Increasing evidence indicates that AhR critically regulates osteoclast differentiation and activity, thereby influencing bone mass, bone resorption, and susceptibility to skeletal diseases. Although AhR has also been implicated in osteoblast-lineage cells, its regulatory roles in osteoclasts and immune cells are less well understood but are increasingly recognized as central to bone remodeling. In particular, AhR signaling modulates immune cell subsets relevant to bone metabolism and governs the differentiation of bone marrow-derived macrophages into osteoclasts.
Highlight: This review summarizes the recent findings regarding the regulation of osteoclast differentiation by AhR and its ligands under both physiological and pathological conditions. Special emphasis is placed on the interaction between AhR and the RANKL signaling axis in osteoclasts, as well as on how exogenous and endogenous ligands, including benzo[a]pyrene (B[a]P) and 6-formylindolo[3,2-b]carbazole (FICZ), modulate bone resorption and subchondral bone remodeling in temporomandibular joint osteoarthritis. Furthermore, the role of macrophages as osteoclast progenitors and immunomodulators has been highlighted, positioning AhR as a critical intermediary that links environmental exposure, inflammation, and skeletal metabolism.
Conclusion: In this review, we outlined the diverse functions of AhR signaling and its ligands in oral and temporomandibular joint osteoarthritis. AhR plays a central role in bone remodeling. The harmful exogenous ligand B[a]P generally promotes bone loss, whereas the endogenous ligand FICZ exerts protective actions. These insights highlight AhR as a key regulatory switch linking the skeletal and immune systems and as a promising therapeutic target for bone-destructive disorders. en-copyright= kn-copyright= en-aut-name=IzawaTakashi en-aut-sei=Izawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HutamiIslamy Rahma en-aut-sei=Hutami en-aut-mei=Islamy Rahma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshikawaYuri en-aut-sei=Yoshikawa en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KozakiGohji en-aut-sei=Kozaki en-aut-mei=Gohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaYusaku en-aut-sei=Hamada en-aut-mei=Yusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NambaYuki en-aut-sei=Namba en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaguchiMisa en-aut-sei=Taguchi en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChenJiamin en-aut-sei=Chen en-aut-mei=Jiamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HabumugishaJanvier en-aut-sei=Habumugisha en-aut-mei=Janvier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthodontics, Universitas Islam Sultan Agung kn-affil= affil-num=3 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Aryl hydrocarbon receptor (AhR) kn-keyword=Aryl hydrocarbon receptor (AhR) en-keyword=AhR ligands kn-keyword=AhR ligands en-keyword=Osteoclasts kn-keyword=Osteoclasts en-keyword=Arthritis kn-keyword=Arthritis en-keyword=Temporomandibular joint osteoarthritis kn-keyword=Temporomandibular joint osteoarthritis END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=3 article-no= start-page=491 end-page=498 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful management and 10-year survival of a rectal neuroendocrine tumor with rare systemic metastases via a non-portal venous pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metastatic neuroendocrine tumors (NETs) typically involve the liver and lymph nodes. Metastases in the orbit, heart, and ovary are rare and present unique clinical challenges. We report a woman who was 70 years old at the time of initial presentation with liver metastases from a rectal neuroendocrine tumor. Following a right hepatectomy for liver metastases, she remained free of hepatic recurrence for 10 years. Notably, four years after the right hepatectomy, she developed new metastases in the left orbit, right ventricle, and left ovary, with diplopia as the sole clinical symptom. This clinical course suggests a distinct metastatic pathway associated with the lower rectum that bypasses the portal circulation, consistent with the dual drainage system of the rectal region. Management involved a strategic multimodal approach that includes systemic therapy with everolimus and lanreotide as well as targeted surgical resectioning of the cardiac and ovarian lesions. The orbital lesion achieved a complete response through systemic therapy alone, preserving visual function. Currently, 10 years after the initial treatment, the patient maintains an excellent performance status (ECOG PS 0) while receiving peptide receptor radionuclide therapy (PRRT). This case demonstrates that recognizing atypical metastatic pathways and employing strategic multimodal therapies can achieve long-term survival and functional preservation in rectal NETs. en-copyright= kn-copyright= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru 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=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KuiseTakashi en-aut-sei=Kuise en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=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=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= 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 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 Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama Red Cross Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Rectal neuroendocrine tumor kn-keyword=Rectal neuroendocrine tumor en-keyword=Rare metastases kn-keyword=Rare metastases en-keyword=Multimodal treatment kn-keyword=Multimodal treatment END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page=8863202 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=Selective ARID1A Loss Restricted to the Undifferentiated Component of a Mismatch Repair‐Deficient Gastric Carcinoma: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mismatch repair-deficient (dMMR) gastric carcinomas often harbor ARID1A alteration, but a sharply demarcated undifferentiated/rhabdoid component with selective ARID1A loss is uncommon and may create a diagnostic dilemma. An 80-year-old man underwent esophagogastroduodenoscopy for anemia, which revealed a circumferential Borrmann Type 3 lesion in the gastric body, and distal gastrectomy was performed. Histologically, the tumor was composed predominantly of undifferentiated carcinoma with focal rhabdoid features and a minute well-differentiated adenocarcinoma component, with an abrupt transition between the two. Immunohistochemistry showed loss of nuclear MLH1 and PMS2 in both components, whereas loss of ARID1A expression was confined to the undifferentiated component; SMARCB1 (INI1), SMARCA2 (BRM), and SMARCA4 (BRG1) were retained. EBER in situ hybridization was negative. Because gene-level testing, MSI testing, and MLH1 promoter methylation analysis were not performed, the molecular basis of the dMMR phenotype and ARID1A loss could not be determined. The restricted scope of molecular testing limits the ability to draw broad or generalizable conclusions and to fully establish clinicopathological correlations. The value of this report is, therefore, not mechanistic proof but recognition of a practical morphologic-immunophenotypic observation: When a gastric carcinoma shows a sharply demarcated shift from differentiated to undifferentiated/rhabdoid morphology, dMMR should be considered, and selective ARID1A loss in the undifferentiated component may be associated with dedifferentiation. These findings should be interpreted with caution as preliminary, hypothesis-generating observations that require validation in larger studies with more extensive molecular profiling. en-copyright= kn-copyright= en-aut-name=OmoteRika en-aut-sei=Omote en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamanoRyosuke en-aut-sei=Hamano en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Diagnostic Pathology, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Hospital kn-affil= en-keyword=ARID1A kn-keyword=ARID1A en-keyword=carcinoma kn-keyword=carcinoma en-keyword=DNA mismatch repair deficiency kn-keyword=DNA mismatch repair deficiency en-keyword=rhabdoid features kn-keyword=rhabdoid features en-keyword=stomach neoplasms kn-keyword=stomach neoplasms en-keyword=SWI/SNF complex kn-keyword=SWI/SNF complex en-keyword=undifferentiated kn-keyword=undifferentiated END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=4 article-no= start-page=829 end-page=838 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Differences in drug efficacy and prognosis between primary and metastatic sites for de novo stage IV breast cancer: an exploratory analysis of a phase III trial, JCOG1017 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Breast cancer is a highly heterogeneous disease, with biological factors like estrogen receptor, progesterone receptor, and HER2 receptor differing between primary and metastatic sites, potentially affecting treatment response.
This exploratory analysis aims to differentiate drug efficacy and long-term prognosis between these sites in stage IV breast cancer.
Methods Patients from JCOG1017, a phase III trial evaluating the role of primary tumor resection, who received primary systemic therapy (PST) were evaluated at three months. In this analysis, treatment response was assessed separately in primary and metastatic sites. Patients were categorized into four groups: discordant I (primary non-PD, metastatic PD), concordant I (both PD), discordant II (primary PD, metastatic non-PD), and concordant II (both non-PD).
Results Among 271 patients, overall discordance proportion of treatment response between primary and metastatic sites was 25.1%. Group distribution was 24.7% (discordant I), 9.6% (concordant I), 0.4% (discordant II), and 65.3% (concordant II). Discordance was more frequent in luminal (28.9%), triple-negative (25.0%), and luminal-HER2 (22.0%) subtypes than in HER2-enriched (11.1%). Survival analysis showed prognostic differences: concordant II, with both sites non-PD, demonstrated the most favorable outcome compared with discordant I (HR 0.556; 95% confidence interval, 0.396–0.782).
Conclusions One-fourth of patients exhibited discordant responses between primary and metastatic sites in early treatment phases. These discrepancies were associated with survival differences, emphasizing the importance of evaluating both primary and metastatic lesions when assessing efficacy and determining treatment strategies in de novo stage IV breast cancer. en-copyright= kn-copyright= en-aut-name=TanakaKiyo en-aut-sei=Tanaka en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

complete response and predictive factors in HER2-positive early breast cancer treated with neoadjuvant chemotherapy aimed at omission of surgery: an exploratory analysis of the JCOG1806 trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The JCOG1806 trial (jRCTs031190129) is underway to evaluate the omission of surgery in patients with human epidermal growth factor receptor (HER2)-positive early breast cancer who have a clinical complete response (cCR) after primary systemic therapy (PST). We aimed to assess the cCR rate in this trial and identify predictive factors.
Methods HER2-positivity was defined as an immunohistochemistry (IHC) score of 3 + or in situ hybridization-positivity. A cCR was defined as the absence of detectable lesions upon palpation, contrast-enhanced magnetic resonance imaging, and ultrasonography; biopsy-based confirmation was optional in hormone receptor (HR)-negative cases and mandatory in HR-positive cases. Multivariate logistic regression analyses were used to identify predictors of a cCR.
Results The cCR rate was 57.6% (196/340 patients; 95% confidence interval [CI]: 52.2–63.0%). Strongly estrogen-receptor (ER)-positive tumors (≥ 10%) were significantly less likely to have a cCR than ER-negative tumors (odds ratio [OR], 0.41; 95% CI: 0.20–0.81). IHC 3 + tumors had higher cCR rates than IHC 1 + or 2 + tumors (OR, 2.19; 95% CI: 1.01–4.74). Compared with histological grade I tumors, cCR odds were higher in grade II (OR: 2.92; 95% CI: 1.07–7.93) and III (OR: 4.90; 95% CI: 1.76–13.7) tumors. Among patients without a cCR patients undergoing surgery, 22.2% were diagnosed with ypT0 tumors upon analysis of surgical specimens.
Conclusion ER-negativity, an IHC score of 3 + , and a higher histological grade were independent predictors of a cCR. Identifying these features may improve the feasibility and safety of surgery omission for patients with HER2-positive early breast cancer. en-copyright= kn-copyright= en-aut-name=ShigematsuHideo en-aut-sei=Shigematsu en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujisawaTomomi en-aut-sei=Fujisawa en-aut-mei=Tomomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraFumikata en-aut-sei=Hara en-aut-mei=Fumikata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwataHiroji en-aut-sei=Iwata en-aut-mei=Hiroji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshibaToshiyuki en-aut-sei=Ishiba en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiYukinori en-aut-sei=Ozaki en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaiTakehiko en-aut-sei=Sakai en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SagaraYasuaki en-aut-sei=Sagara en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShimomuraAkihiko en-aut-sei=Shimomura en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SudoKazuki en-aut-sei=Sudo en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TerataKaori en-aut-sei=Terata en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NaitoYoichi en-aut-sei=Naito en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NozawaKazuki en-aut-sei=Nozawa en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SasakiKeita en-aut-sei=Sasaki en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MitomeNoriko en-aut-sei=Mitome en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=SadachiRyo en-aut-sei=Sadachi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=ShibataTaro en-aut-sei=Shibata en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 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=18 ORCID= affil-num=1 en-affil=Department of Surgical Oncology, Research Institute for Radiation Biology and Medicine, Hiroshima University Hospital kn-affil= affil-num=2 en-affil=Gunma Prefectural Cancer Center kn-affil= affil-num=3 en-affil=Aichi Cancer Center kn-affil= affil-num=4 en-affil=Graduate School of Medical Sciences, Nagoya City University kn-affil= affil-num=5 en-affil=Institute of Science Tokyo Hospital kn-affil= affil-num=6 en-affil=Cancer Institute Hospital of the Japanese Foundation for Cancer Research kn-affil= affil-num=7 en-affil=Cancer Institute Hospital of the Japanese Foundation for Cancer Research kn-affil= affil-num=8 en-affil=Hakuaikai Sagara Hospital kn-affil= affil-num=9 en-affil=National Center for Global Health and Medicine kn-affil= affil-num=10 en-affil=National Cancer Center Hospital kn-affil= affil-num=11 en-affil=Akita University Hospital kn-affil= affil-num=12 en-affil=National Cancer Center Hospital East kn-affil= affil-num=13 en-affil=Graduate School of Medical Sciences, Nagoya City University kn-affil= affil-num=14 en-affil=Japan Clinical Oncology Group Data Center/Operations Office, National Cancer Center Hospital kn-affil= affil-num=15 en-affil=Japan Clinical Oncology Group Data Center/Operations Office, National Cancer Center Hospital kn-affil= affil-num=16 en-affil=Japan Clinical Oncology Group Data Center/Operations Office, National Cancer Center Hospital kn-affil= affil-num=17 en-affil=Japan Clinical Oncology Group Data Center/Operations Office, National Cancer Center Hospital kn-affil= affil-num=18 en-affil=Okayama University Hospital kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Primary systemic therapy kn-keyword=Primary systemic therapy en-keyword=HER2 kn-keyword=HER2 en-keyword=cCR kn-keyword=cCR en-keyword=Omission of surgery kn-keyword=Omission of surgery END start-ver=1.4 cd-journal=joma no-vol=208 cd-vols= no-issue=6 article-no= start-page=2124 end-page=2133 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decreased renal function predicts severe cytokine release syndrome after CAR-T-cell therapy for large B-cell lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cytokine release syndrome (CRS) remains a major toxicity of chimeric antigen receptor (CAR) T-cell therapy in large B-cell lymphoma (LBCL), and robust pre-infusion predictors are needed for risk-adapted management. We retrospectively analysed LBCL patients in the Japanese nationwide registry who underwent CD19 CAR-T-cell therapy between 2019 and 2024. Among 900 patients (median age 62 years), cumulative incidences of CRS within 30 days after infusion were 75.0% for any grade, 20.8% for grade ≥ 2 and 14.0% for grade ≥ 3. In multivariable analysis, lower estimated glomerular filtration rate (eGFR) (adjusted hazard ratio [aHR] 1.108 per 10 mL/min per 1.73 m2 decrease; 95% confidence interval [CI] 1.015–1.209; p = 0.022), higher ferritin (aHR 1.006 per 100 ng/mL; 95% CI 1.001–1.010; p = 0.016), C-reactive protein (CRP) (aHR 1.142 per mg/dL; 95% CI 1.091–1.195; p < 0.001) and lactate dehydrogenase (LDH) (aHR 1.073 per 100 U/L; 95% CI 1.008–1.142; p = 0.028) independently predicted grade ≥ 2 CRS. We then built a four-factor CRS pre-infusion risk evaluation model, cytokine release syndrome-pre-infusion risk evaluation (CRS-PRE), that stratified grade ≥ 2 CRS risk into low, intermediate and high groups with incidences of 2.8%, 26.0% and 50.0% respectively. Decreased eGFR, a surrogate of host renal reserve, with elevated ferritin, CRP and LDH emerged as predictors of high-grade CRS. The CRS-PRE may facilitate risk-adapted monitoring and intervention in clinical practice. en-copyright= kn-copyright= en-aut-name=AraiYasuyuki en-aut-sei=Arai en-aut-mei=Yasuyuki kn-aut-name=

kn-subtitle= en-abstract= kn-abstract=Background: Social comparison and envy are significant psychosocial stressors in humans and are known to be involved in the onset and persistence of psychiatric disorders. However, animal models capable of experimentally reproducing the effects of indirect social comparison without physical contact are limited. In this study, we used a newly developed "adjacent-cage paradigm" to investigate whether chronic vicarious exposure to conspecifics in different environments induces envy-like stress in mice.
Methods: Male C57BL/6 N mice served as observers, while demonstrator mice were assigned to one of four conditions: (1) an environment enriched with objects, (2) an igloo, (3) a tube, or (4) social isolation. Observers were continuously exposed to these adjacent cages for 21 days. Subsequently, a comprehensive battery of behavioral tests was conducted to assess general health, anxiety-like behavior, spatial memory, social behavior, and depression-like behavior.
Results: In the objects condition, a decrease in time spent in the light compartment of the light/dark box indicated an increase in anxiety-like behavior. In the isolation condition, the mean duration per social interaction was shortened, suggesting a qualitative change in social behavior. The igloo condition resulted in reduced immobility time in the forced swim test, suggesting a possible alteration in stress coping behavior. Furthermore, increased nociceptive sensitivity was observed in the hot plate test under both the objects and isolation conditions.
Conclusion: Although the envy-like stress paradigm did not affect many behavioral indices, it did cause condition-dependent and limited behavioral changes. This suggests that the paradigm may serve as a novel model for capturing psychological and context-dependent social stress, which differs from conventional physical stress models. Elucidating the neural basis of this paradigm is expected to contribute to the understanding of how social comparison affects mental health in modern society. en-copyright= kn-copyright= en-aut-name=UenoHiroshi en-aut-sei=Ueno en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaYoshihiro en-aut-sei=Tanaka en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitanoEriko en-aut-sei=Kitano en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriSachiko en-aut-sei=Mori en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurakamiShinji en-aut-sei=Murakami en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WaniKenta en-aut-sei=Wani en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkamotoMotoi en-aut-sei=Okamoto en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshiharaTakeshi en-aut-sei=Ishihara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Medical Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=2 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=8 en-affil=Department of Neuropsychiatry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= en-keyword=envy-like stress kn-keyword=envy-like stress en-keyword=social comparison kn-keyword=social comparison en-keyword=psychosocial stress kn-keyword=psychosocial stress en-keyword=mouse model kn-keyword=mouse model en-keyword=anxiety-like behavior kn-keyword=anxiety-like behavior END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=15771 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adolescent envy-like social comparison stress induces HPA axis hypoactivity and anxiety in female mice: implications for somatic symptom disorder en-subtitle= kn-subtitle= en-abstract= kn-abstract=Adolescence is a critical developmental window marked by heightened neuroplasticity and maturation of the stress response system, conferring vulnerability to psychosocial stress. Chronic stress during this period increases the risk of anxiety and depressive disorders and may contribute to somatic symptom disorder (SSD), which is characterized by medically unexplained physical complaints and shows a striking female predominance. The impact of envy-like stress arising from social comparison, a pervasive psychosocial factor in modern society, remains poorly understood. Male and female C57BL/6N mice were exposed to chronic envy-like stress from postnatal day (P)21 to P52 by housing them adjacent to enriched cages, while control mice were housed without such exposure. From P52 onward, mice underwent behavioral testing of anxiety-like behavior, exploratory activity, social interaction, spatial working memory, motor coordination, nociception, and depression-like behavior. Serum corticosterone and adrenocorticotropic hormone (ACTH) concentrations were measured to assess hypothalamic–pituitary–adrenal (HPA) axis function. Envy-like stress induced sex-specific phenotypes. Male mice exhibited hyperactivity, reduced social interaction, and impaired spatial working memory. In contrast, female mice displayed robust increases in anxiety-like behavior, impaired motor coordination, and significant reductions in basal corticosterone and ACTH levels. Chronic envy-like stress during adolescence elicits distinct, sex-dependent behavioral and endocrine alterations. The phenotype observed in female mice—characterized by heightened anxiety and lower basal HPA axis hormone levels—shares some biological features with clinical observations in SSD. This model may serve as a starting point for elucidating the mechanisms linking psychosocial stress and somatic symptoms in a sex-dependent manner. en-copyright= kn-copyright= en-aut-name=UenoHiroshi en-aut-sei=Ueno en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaYoshihiro en-aut-sei=Tanaka en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitanoEriko en-aut-sei=Kitano en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriSachiko en-aut-sei=Mori en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurakamiShinji en-aut-sei=Murakami en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WaniKenta en-aut-sei=Wani en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkamotoMotoi en-aut-sei=Okamoto en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshiharaTakeshi en-aut-sei=Ishihara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Medical Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=2 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=8 en-affil=Department of Neuropsychiatry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= en-keyword=Envy-like stress kn-keyword=Envy-like stress en-keyword=Social comparison kn-keyword=Social comparison en-keyword=Adolescence kn-keyword=Adolescence en-keyword=HPA axis kn-keyword=HPA axis en-keyword=Somatic symptom disorder (SSD) kn-keyword=Somatic symptom disorder (SSD) en-keyword=Sex differences kn-keyword=Sex differences en-keyword=Psychosocial stress kn-keyword=Psychosocial stress END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=44248 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Post-weaning maternal presence exerts a protective effect against social isolation-induced behavioural alterations in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parental “watchful presence” is considered an important factor influencing behavioural and emotional development in offspring across mammalian species, including humans. However, the effects of such parental presence remain insufficiently understood, even in human studies. In laboratory mice, offspring are typically weaned at approximately three weeks of age, leaving the impact of post-weaning maternal presence on behavioural development largely unexplored. This study aimed to investigate whether maternal presence in an adjacent cage after weaning can attenuate behavioural effects of social isolation stress in mice. Furthermore, we sought to assess whether this experimental paradigm could serve as a novel animal model for studying the effects of parental watchful presence, with potential relevance to human parent–child relationship research. Mouse pups were weaned at postnatal day 21 and housed either adjacent to their mother (maternal presence group) or without maternal presence (control group). The pups were subsequently housed either in groups with littermates or individually until eight weeks of age. After maturation, behavioural tests were conducted to assess locomotor activity, anxiety-like behaviour, social behaviour, and depression-like behaviour. In group-housed mice, maternal presence did not influence behavioural outcomes. However, in individually housed mice, maternal presence partially attenuated social isolation-induced behavioural alterations, suggesting a subtle protective effect, including hyperlocomotion, reduced anxiety-like behaviour, and abnormal social interactions. Our findings demonstrate that maternal presence during the post-weaning period can offer a protective effect against certain behavioural abnormalities induced by social isolation stress in mice. This simple adjacent-cage paradigm provides a novel and practical model for elucidating the impact of parental watchful presence on behavioural and emotional development, offering insights relevant to the understanding of parent–child relationships in humans. en-copyright= kn-copyright= en-aut-name=UenoHiroshi en-aut-sei=Ueno en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitanoEriko en-aut-sei=Kitano en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriSachiko en-aut-sei=Mori en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiShinji en-aut-sei=Murakami en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WaniKenta en-aut-sei=Wani en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoMotoi en-aut-sei=Okamoto en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshiharaTakeshi en-aut-sei=Ishihara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Medical Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=2 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Neuropsychiatry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= en-keyword=Maternal presence kn-keyword=Maternal presence en-keyword=Social isolation kn-keyword=Social isolation en-keyword=Post-weaning period kn-keyword=Post-weaning period en-keyword=Resilience kn-keyword=Resilience en-keyword=Mice kn-keyword=Mice END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=6 article-no= start-page=1063 end-page=1074 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Barriers and facilitators for online genetic care for hereditary cancer in Japan: findings from surveys of both clients and medical professionals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Online genetic care can offer a promising solution to the shortage of qualified medical professionals in genetic medicine, which leads to regional disparities in access. However, despite global adoption, its use in Japan remains limited.
Methods Two questionnaire surveys were conducted to investigate potential needs and barriers regarding online genetic care: one involving 858 medical professionals (738 physicians and 120 genetic counselors or nurses), and the other involving 443 clients who received in-person genetic counseling.
Results Only 14.0% of the medical professionals had experience with online genetic care, although 85.9% of the professionals engaged in cancer genetics were willing to consider providing it in the future. Notably, a discrepancy was found regarding hospital selection: clients prioritized access to specialized medical care, whereas professionals assumed clients valued accessibility for family members. Professionals expressed greater concerns about adequacy of online communication, client environments and internet security. Among clients, 89.1% estimated they would sufficiently understand and accept total content of counseling session if were conducted online. Older age and infrequent internet use were associated with lower acceptance and higher anxiety regarding online methods. Concerns about ability to use the necessary technology affected clients’ willingness to encourage online care for their relatives.
Conclusion Online genetic care shows high potential for client acceptance and can effectively address regional disparities in Japan. To bridge the gap between client needs and professional perceptions and to overcome the digital divide, it is necessary to develop secure, accessible systems and provide education for both patients and healthcare providers. en-copyright= kn-copyright= en-aut-name=UenoSayaka en-aut-sei=Ueno en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UrakawaYusaku en-aut-sei=Urakawa en-aut-mei=Yusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoFumino en-aut-sei=Kato en-aut-mei=Fumino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UekiArisa en-aut-sei=Ueki en-aut-mei=Arisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanekoKeika en-aut-sei=Kaneko en-aut-mei=Keika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoKoji en-aut-sei=Matsumoto en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugawaraHiromi en-aut-sei=Sugawara en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiSayoko en-aut-sei=Takeuchi en-aut-mei=Sayoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaReiko en-aut-sei=Yoshida en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KakutaMiho en-aut-sei=Kakuta en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkagiKiwamu en-aut-sei=Akagi en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TamuraKazuo en-aut-sei=Tamura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil=Division of Clinical Genetic Oncology, Cancer Institute Hospital, Japanese Foundation for Cancer Research kn-affil= affil-num=5 en-affil=Division of Clinical Genetic Oncology, Cancer Institute Hospital, Japanese Foundation for Cancer Research kn-affil= affil-num=6 en-affil=Division of Clinical Genetics, Hyogo Cancer Center kn-affil= affil-num=7 en-affil=Division of Clinical Genetics, Hyogo Cancer Center kn-affil= affil-num=8 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Medical Genetics and Genomics, Saitama Cancer Center kn-affil= affil-num=10 en-affil=Center for Genomic Diagnosis, International University of Health and Welfare (IUHW) Narita Hospital kn-affil= affil-num=11 en-affil=Center for Genomic Diagnosis, International University of Health and Welfare (IUHW) Narita Hospital kn-affil= affil-num=12 en-affil=Center for Genomic Diagnosis, International University of Health and Welfare (IUHW) Narita Hospital kn-affil= affil-num=13 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Hereditary cancer kn-keyword=Hereditary cancer en-keyword=Remote medical care kn-keyword=Remote medical care en-keyword=Barriers to online genetic care kn-keyword=Barriers to online genetic care en-keyword=Facilitators for online genetic care kn-keyword=Facilitators for online genetic care END start-ver=1.4 cd-journal=joma no-vol=827 cd-vols= no-issue= article-no= start-page=154001 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=Staphylococcus aureus activates dendrite elongation in dendritic cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dendritic cells (DCs) are thought to extend dendrites to enhance the efficiency of antigen uptake and presentation. We previously reported that short-chain fatty acids (SCFAs), such as butyrate and valerate, promote dendrite extension in DCs. In this study, we found that the human pathogen Staphylococcus aureus also induces dendrite extension in DCs and investigated the underlying mechanisms. Dendrite extension in DC2.4 cells was induced not only by live S. aureus but also by heat-killed bacteria and purified peptidoglycan (PGN). DC2.4 cells lacking TLR2 or its adaptor protein MyD88 extend dendrites in response to SCFAs, but failed to extend dendrites in response to S. aureus. Furthermore, inhibitors of ERK, PI3K, and Cdc42 suppressed dendrite extension triggered by S. aureus. Co-stimulation with S. aureus and butyrate enhanced dendrite extension beyond either stimulus alone. DC2.4 cells co-stimulated with S. aureus and butyrate also showed increased uptake of insoluble beads and, upon co-culture with T cells, induced elevated production of IL-17 and IL-10 by T cells. Collectively, these findings suggest that S. aureus activates ERK/PI3K/Cdc42 signaling through TLR2 recognition of PGN to drive dendrite extension in DCs. In addition, S. aureus promotes dendrite extension in DCs via a pathway distinct from that of SCFAs, thereby acting cooperatively with SCFAs to enhance immune responses. en-copyright= kn-copyright= en-aut-name=KobataKai en-aut-sei=Kobata en-aut-mei=Kai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=IkeyaYuki en-aut-sei=Ikeya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChishakiYohei en-aut-sei=Chishaki en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Staphylococcus aureus kn-keyword=Staphylococcus aureus en-keyword=Dendritic cells kn-keyword=Dendritic cells en-keyword=Dendrite elongation kn-keyword=Dendrite elongation en-keyword=Peptidoglycan: TLR2/MyD88 signaling kn-keyword=Peptidoglycan: TLR2/MyD88 signaling en-keyword=ERK/PI3K/Cdc42 pathway kn-keyword=ERK/PI3K/Cdc42 pathway en-keyword=Short-chain fatty acids (SCFAs) kn-keyword=Short-chain fatty acids (SCFAs) en-keyword=Butyrate kn-keyword=Butyrate en-keyword=Host–microbe interactions kn-keyword=Host–microbe interactions en-keyword=Antigen presentation kn-keyword=Antigen presentation en-keyword=T-cell activation kn-keyword=T-cell activation en-keyword=IL-17 kn-keyword=IL-17 en-keyword=IL-10 kn-keyword=IL-10 END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=2 article-no= start-page=25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Machine learning prediction of the Madden–Julian oscillation using reservoir computing en-subtitle= kn-subtitle= en-abstract= kn-abstract=The prediction of the Madden–Julian Oscillation (MJO), a massive tropical weather event with global socio-economic impacts, has been infamously difficult with physics-based weather prediction models. We employ the reservoir computing, a brain-inspired machine-learning technique, to construct a machine learning model that forecasts the real-time multivariate MJO index (RMM), a macroscopic variable that represents the state of the MJO. The training data was refined by development of a novel real-time band-pass filter that extracts the recurrency of MJO signals only from the past raw atmospheric data, and by selection of a suitable time-delay coordinate of the RMM that enhances the recurrency of the input data. The constructed model demonstrated the skill to forecast the time sequence of the RMM for a month from pre-developmental stages of the MJO. Examination of best-performing cases suggested that RMM sequences may be predicted for over two months in some cases. These results imply that inherent predictability limit of the MJO is longer than that has been estimated from physics-based weather prediction models. en-copyright= kn-copyright= en-aut-name=SuematsuTamaki en-aut-sei=Suematsu en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaiKengo en-aut-sei=Nakai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YonedaTsuyoshi en-aut-sei=Yoneda en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasukaDaisuke en-aut-sei=Takasuka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JinnoTakuya en-aut-sei=Jinno en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaikiYoshitaka en-aut-sei=Saiki en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiuraHiroaki en-aut-sei=Miura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=RIKEN Center for Computational Science kn-affil= affil-num=2 en-affil=Graduate School of Environmental Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Economics, Hitotsubashi University kn-affil= affil-num=4 en-affil=Department of Geophysics, Tohoku University kn-affil= affil-num=5 en-affil=Graduate School of Science, The University of Tokyo kn-affil= affil-num=6 en-affil=Graduate School of Business Administration, Hitotsubashi University kn-affil= affil-num=7 en-affil=Graduate School of Science, The University of Tokyo kn-affil= en-keyword=Reservoir computing kn-keyword=Reservoir computing en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Madden–Julian Oscillation kn-keyword=Madden–Julian Oscillation en-keyword=Sub-seasonal forecast kn-keyword=Sub-seasonal forecast END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=pcag052 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cytokinin receptor AHK3 influences leaf size by modulating trans-zeatin-type cytokinin levels in xylem en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trans-zeatin (tZ)-type cytokinins (CKs) are predominantly synthesized in roots, transported to the shoot via the xylem, and coordinate diverse physiological processes in aerial organs. Within this process, the regulation of CK biosynthesis by nitrate signaling via nodule inception-like protein 7, as well as the loading of tZ-type CKs into the xylem by ATP-binding cassette transporter G14, have been well studied. However, the roles of other components remain unclear. Here, we show that CK perception and degradation in roots, as mediated by Arabidopsis histidine kinase 3 (AHK3) and CK oxidase/dehydrogenase 4 (CKX4), modulate root-to-shoot tZ-type cytokinin transport in response to nitrate. Grafting experiments demonstrate that root-specific AHK3 deficiency systemically increases the leaf blade area through long-distance signals of root-derived tZ-type CKs, perceived by shoot-expressed AHK3. Transcriptome and hormonome analyses reveal that root-specific AHK3 deficiency reduces CKX4 expression in roots, elevating tZ-type CK levels in roots and xylem sap and thereby enhancing the leaf CK response. Transfer experiments manipulating root nitrate levels show that root-specific AHK3 deficiency promotes the leaf blade area in a manner dependent on both nitrate and root-derived tZ-type CK signaling. Moreover, both nitrate signals and root-expressed AHK3 are required for maximal CKX4 induction in roots, and root-specific CKX4 deficiency enhances the leaf blade area in a nitrate-dependent manner. These findings reveal a novel mechanism in which an AHK3–CKX4 module governs xylem transport of tZ-type CKs, fine-tuning leaf size according to root nitrate status. en-copyright= kn-copyright= en-aut-name=MondenKota en-aut-sei=Monden en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiTakamasa en-aut-sei=Suzuki en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KojimaMikiko en-aut-sei=Kojima en-aut-mei=Mikiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakebayashiYumiko en-aut-sei=Takebayashi en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiyaTakehiro en-aut-sei=Kamiya en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KibaTakatoshi en-aut-sei=Kiba en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakakibaraHitoshi en-aut-sei=Sakakibara en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakagawaTsuyoshi en-aut-sei=Nakagawa en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HachiyaTakushi en-aut-sei=Hachiya en-aut-mei=Takushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=3 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=4 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=5 en-affil=Graduate School of Agricultural and Life Sciences, Tokyo University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=8 en-affil=Department of Molecular and Functional Genomics, Interdisciplinary Centerfor Science Research, Shimane University kn-affil= affil-num=9 en-affil=Department of Molecular and Functional Genomics, Interdisciplinary Centerfor Science Research, Shimane University kn-affil= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=cytokinin kn-keyword=cytokinin en-keyword=micrografting kn-keyword=micrografting en-keyword=nitrate signal kn-keyword=nitrate signal en-keyword=trans-zeatin kn-keyword=trans-zeatin END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=23 article-no= start-page=2473 end-page=2478 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=Synthesis of a BC6 polymer via cyclotrimerization of alkynylborane and its application as a heterogeneous Lewis acid catalyst en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lewis acidic boron-containing π-conjugated polymer materials have been demonstrated to be promising for sensing and catalysis; however, the synthetic approaches and the number of installed boron atoms have been limited. Herein, we report the synthesis of a BC6 polymer structure via cyclotrimerization of alkynes. The resulting polymer exhibited superior catalytic activity to small-molecule analogues such as BPh3 and previously reported boron-containing polymers. This enhanced performance is attributed to the high boron content and increased Lewis acidity of BC6, as supported by theoretical and experimental analyses. Owing to its polymeric nature, the catalyst was readily recovered and reused in the catalytic system. These findings demonstrate that building rigid polymer frameworks with a high density of Lewis acidic boron sites is a promising approach to developing recyclable heterogeneous Lewis acid catalysts, and offers a broadly applicable design principle for functional boron-containing polymeric materials. en-copyright= kn-copyright= en-aut-name=TakahashiNaoki en-aut-sei=Takahashi en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhkuraKentaro en-aut-sei=Ohkura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, 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=20260613 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel robot for CT-guided bone needle insertion with a rotational drilling and force-feedback speed control mechanism: preliminary evaluation in swine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To evaluate the feasibility and accuracy of computed tomography (CT)-guided needle insertion into swine bones by using a novel robotic system capable of rotational drilling.
Materials and methods This was an animal experiment using three swine. A remote-controlled robot equipped with a rotational drilling and force-feedback insertion speed control mechanism was developed for bone needle insertion. Using the robot, CT-guided insertion of a 10-gauge bone access needle was attempted in the lumbar vertebrae, ilia, and femora six times each. Needle insertion accuracy was evaluated using the angle error, which is defined as the difference between the predetermined and post-insertion needle angles on axial and sagittal CT images. The time required for needle insertion was measured. The angle error and time required for needle insertion were compared among the bones using the Kruskal–Wallis test. Adverse events were also evaluated.
Results Robotic bone needle insertion was successful in all attempts. The median axial and sagittal angle errors were 0.21 and 0.21° for the lumbar vertebrae, 0.32 and 0.13° for the ilia, and 0.65 and 0.25° for the femora, respectively. Axial angle errors were significantly different among the bone types (p = 0.038). The time required for needle insertion was 23.6, 21.3, and 59.7 s for the lumbar vertebrae, ilia, and femora, respectively. Time was significantly different among bone types (p = 0.017). No adverse events were observed.
Conclusion CT-guided bone needle insertion using a robot equipped with a rotational drilling and force-feedback insertion speed control mechanism was feasible and accurate in swine. 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=KimuraYuta en-aut-sei=Kimura en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasakiTakanori en-aut-sei=Sasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuuraRyutaro en-aut-sei=Matsuura en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=OkamotoSoichiro en-aut-sei=Okamoto en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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=11 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=12 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=13 ORCID= en-aut-name=MatsumiyaKiyoshi en-aut-sei=Matsumiya en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 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=16 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, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Collaborative Research Center for OMIC, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=10 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=11 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=13 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=14 en-affil=Department of Medical Technology, Faculty of Life Science, Okayama University of Science kn-affil= affil-num=15 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=16 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Robot kn-keyword=Robot en-keyword=Needle kn-keyword=Needle en-keyword=Bone kn-keyword=Bone en-keyword=CT-guided kn-keyword=CT-guided en-keyword=Intervention kn-keyword=Intervention END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=6 article-no= start-page=2645 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=Minimal Association Between Immunoglobulin A Coating and Gut Microbiota Alterations Induced by High-Fat Diets with Distinct Fatty Acid Compositions en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-fat diets (HFDs) containing dietary fats with different fatty acid (FA) compositions alter gut microbiota composition in a fat-source-dependent manner. Immunoglobulin A (IgA) and unabsorbed lipids in the distal gut are potential regulators of the gut microbiota. However, their roles in mediating gut microbiota alterations induced by dietary fats with different FA compositions remain unclear. This study aims to examine the associations of these two factors with fat-source-dependent gut microbiota alterations. BALB/c mice were fed a normal diet, a high-lard diet, a high-olive oil diet, or a high-soybean oil diet for 27 weeks. Fecal samples were collected to assess microbiota composition, the IgA coating index (ICI)—which quantifies the extent of IgA coating on gut microbiota—and fecal fatty acid concentrations. At the phylum level, the concentration of fecal total long-chain fatty acids (LCFAs) was positively correlated with the relative abundance (RA) of Bacillota and negatively correlated with that of Bacteroidota. In addition, a trend toward a positive association between the RA and the ICI was observed for Bacillota but not for Bacteroidota. At the genus level, the RAs of 12 taxa were positively correlated with fecal LCFA concentrations, whereas those of 6 taxa were negatively correlated. Although the RAs of most taxa appeared to be influenced by unabsorbed lipids and additional factors, only four Bacillota genera exhibited a positive correlation between the RA and the ICI. Our observations suggest that IgA coating of the gut microbiota may have a minimal association with fat-source-specific alterations in gut microbiota composition during HFD intake. en-copyright= kn-copyright= en-aut-name=TeraokaMao en-aut-sei=Teraoka en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=WangTianyang en-aut-sei=Wang en-aut-mei=Tianyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChenKuiyi en-aut-sei=Chen en-aut-mei=Kuiyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=immunoglobulin A kn-keyword=immunoglobulin A en-keyword=high-fat diet kn-keyword=high-fat diet en-keyword=gut microbiota kn-keyword=gut microbiota en-keyword=fatty acid composition kn-keyword=fatty acid composition END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=10 article-no= start-page=1527 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Activation of TAS2R Signaling by Diphenidol Suppresses Tumor Growth and Remodels the Tumor Immune Microenvironment in Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Oral squamous cell carcinoma (OSCC) remains a clinically challenging malignancy characterized by aggressive behavior and limited therapeutic options. Bitter taste receptors (TAS2Rs), expressed across multiple tissues and cancer types, have recently emerged as regulators of tumor biology and immune responses; however, their functional significance in OSCC remains poorly understood. Methods: Immunohistochemical analysis was performed using surgically resected human tongue OSCC specimens and a tissue microarray (TMA) cohort. In parallel, four TAS2R agonists were evaluated in SCC7 cells to assess intracellular calcium responses. RNA sequencing was conducted to analyze transcriptional changes following diphenidol treatment, and functional assays, including proliferation, migration, and apoptosis analyses, were performed in vitro. Antitumor effects were further evaluated in a syngeneic SCC7 mouse model, followed by TUNEL staining and flow cytometry to assess apoptosis and immune cell infiltration. Results: TAS2R38 expression was markedly upregulated in dysplastic and invasive OSCC lesions with predominant nuclear localization and was associated with histological grade and clinical stage, indicating an early and sustained alteration during tumor progression. Among the agonists tested, diphenidol most strongly induced IP3-dependent intracellular Ca2+ elevation. RNA sequencing revealed upregulation of Il1rl1 and Lzts2. Functionally, diphenidol significantly suppressed SCC7 cell proliferation and migration and induced apoptosis in vitro. In vivo, diphenidol reduced tumor volume and weight and increased apoptotic activity. Flow cytometry demonstrated a marked reduction in tumor-infiltrating CD4+CD25+Foxp3+ regulatory T cells, indicating modulation of the tumor immune microenvironment. Conclusions: TAS2R activation by diphenidol suppresses tumor growth through both tumor-intrinsic mechanisms and modulation of the tumor immune microenvironment in OSCC. These findings define TAS2R-mediated calcium signaling as a novel axis linking tumor progression and immunoregulation. Given that diphenidol is a clinically approved drug with an established safety profile, our results provide a strong rationale for TAS2R-targeted drug repurposing strategies in cancer therapy. en-copyright= kn-copyright= en-aut-name=NasrunNisrina Ekayani en-aut-sei=Nasrun en-aut-mei=Nisrina Ekayani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanimuraAkihiko en-aut-sei=Tanimura en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=UeharaOsamu en-aut-sei=Uehara en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=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=HosoyaAkihiro en-aut-sei=Hosoya en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakebeHiroaki en-aut-sei=Takebe en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AbikoYoshihiro en-aut-sei=Abiko en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=RuslinMuhammad en-aut-sei=Ruslin en-aut-mei=Muhammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ShimoTsuyoshi en-aut-sei=Shimo en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Division of Reconstructive Surgery for Oral and Maxillofacial Region, Department of Human Biology and Pathophysiology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=2 en-affil=Division of Pharmacology, Department of Oral Biology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=3 en-affil=Division of Oral Medicine and Pathology, Department of Human Biology and Pathophysiology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=4 en-affil=Division of Disease Control and Molecular Epidemiology, Department of Oral Growth and Development, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Division of Craniofacial Development and Tissue Biology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=8 en-affil=Division of Histology, Department of Oral Biology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Division of Oral Medicine and Pathology, Department of Human Biology and Pathophysiology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Hasanuddin University kn-affil= affil-num=12 en-affil=Division of Reconstructive Surgery for Oral and Maxillofacial Region, Department of Human Biology and Pathophysiology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= en-keyword=bitter taste receptor kn-keyword=bitter taste receptor en-keyword=diphenidol kn-keyword=diphenidol en-keyword=immunometabolism kn-keyword=immunometabolism en-keyword=oral squamous cellcarcinoma kn-keyword=oral squamous cellcarcinoma en-keyword=TAS2R signaling kn-keyword=TAS2R signaling en-keyword=tumor immune microenvironment kn-keyword=tumor immune microenvironment END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=6 article-no= start-page=1319 end-page=1328 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260326 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Institutional Variability in Brain-Dead Organ Donation Processes and Practices: A Multicenter Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=OBJECTIVES: To determine whether key institutional and clinical differences exist between highly and moderately active hospitals in Japan with respect to brain-dead organ donation practices.
DESIGN: Retrospective multicenter cohort study.
SETTING: Sixteen tertiary emergency and critical care centers across Japan.
PATIENTS: All brain-dead organ donors from participating institutions who had at least one organ procured and transplanted between July 17, 2010, and December 31, 2023. Hospitals were categorized as highly active (≥ 14 donations) or moderately active (≤ 13 donations) during the study period.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Institutional donation practices were compared, including donor management strategies, use of vasopressors and corticosteroids, time intervals in the donation process, and frequency of multidisciplinary team meetings. A total of 204 donors were included; the median age was 47 years (interquartile range, 37–56), and 92 (45.1%) were female. Donor characteristics were similar between groups. Vasopressin was used in nearly all donors, though dosing protocols varied. Corticosteroid use was significantly higher in highly active hospitals compared with moderately active ones (58.3% vs. 38.0%; p = 0.004). Time from admission to coordinator notification was similar; however, time to family consent (median, 8 vs. 5 d; p < 0.001) and time to organ procurement (median, 12 vs. 9 d; p = 0.006) were longer in highly active hospitals. These hospitals also conducted more multidisciplinary meetings during donor management (median, 2 vs. 0; p < 0.001).
CONCLUSIONS: Highly active hospitals demonstrated more intensive donor management practices, longer timeframes for key donation steps, and greater multidisciplinary engagement. Standardization of donation practices may enhance efficiency and support broader dissemination of effective institutional strategies to improve brain-dead organ donation rates in Japan. en-copyright=

Localized enrichment of type III collagen and LTBP-4 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcific aortic valve disease (CAVD) is characterized by progressive extracellular matrix (ECM) remodeling that promotes valve fibrosis and calcification. However, its molecular and structural basis remains unclear. In this study, we comprehensively analyzed ECM remodeling in human CAVD valves, focusing on collagen dynamics and key ECM-associated regulatory components. Histopathological analysis revealed fibrous layer thickening, collagen disorganization, and focal loss of the spongiosa in the CAVD group. Polarized picrosirius red staining demonstrated increased yellow-orange birefringence in the fibrotic and calcified regions, indicating altered collagen organization. Quantitative liquid chromatography–mass spectrometry analysis showed region-specific shifts toward an increased type III collagen proportion in fibrotic and calcific regions despite the reduced total collagen content in calcified areas. Collagen with improper triple-helical structure primarily accumulated around the calcified nodules, suggesting abnormal collagen turnover. Transmission electron microscopy revealed thinner and more heterogeneous collagen fibrils in lesioned regions than that in pre-lesional region. In normal valves, immunohistochemistry suggested that the hyaluronan-versican-fibrillin complex contributes to local regulation of Transforming growth factor-beta 1 (TGF-β1) activity via latent TGF-β binding proteins (LTBP); however, this regulatory structure was disrupted in CAVD. Notably, LTBP-4 showed strong, regionally restricted localization in the fibrotic and calcific regions and was positively correlated with collagen yellow-orange birefringence. Collectively, these findings indicate that CAVD is associated with a localized shift toward a structurally heterogeneous, type III collagen-enriched matrix, accompanied by collagen denaturation and abnormal accumulation of LTBP-4, highlighting ECM dysregulation as a key feature of disease progression. en-copyright= kn-copyright= en-aut-name=KemmochiReiko en-aut-sei=Kemmochi en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazakiHaruko en-aut-sei=Miyazaki en-aut-mei=Haruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TagaYuki en-aut-sei=Taga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiNaoki en-aut-sei=Takahashi en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeTakafumi en-aut-sei=Watanabe en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkemuraKentaro en-aut-sei=Ikemura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SasakiTakako en-aut-sei=Sasaki en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MizunoKazunori en-aut-sei=Mizuno en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=MatsumotoMitsuaki en-aut-sei=Matsumoto en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Molecular Biology and Biochemistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Molecular Biology and Biochemistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Nippi Research Institute of Biomatrix kn-affil= affil-num=4 en-affil=Laboratory of Veterinary Anatomy, School of Veterinary Medicine, Rakuno Gakuen University kn-affil= affil-num=5 en-affil=Laboratory of Veterinary Anatomy, School of Veterinary Medicine, Rakuno Gakuen University kn-affil= affil-num=6 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pharmacology, Faculty of Medicine, Oita University kn-affil= affil-num=8 en-affil=Nippi Research Institute of Biomatrix kn-affil= affil-num=9 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Cardiovascular Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=11 en-affil=Department of Molecular Biology and Biochemistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Calcific aortic valve disease kn-keyword=Calcific aortic valve disease en-keyword=Extracellular matrix kn-keyword=Extracellular matrix en-keyword=Type III collagen kn-keyword=Type III collagen en-keyword=TGF-β1 kn-keyword=TGF-β1 en-keyword=Latent TGF-β binding protein-4 kn-keyword=Latent TGF-β binding protein-4 END start-ver=1.4 cd-journal=joma no-vol=288 cd-vols= no-issue= article-no= start-page=108478 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hydrogen-lean two-stage upgrading of highly acidic palm acid oil via decoupled acid reduction and deoxygenation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Upgrading highly acidic waste lipids into liquid hydrocarbons under limited hydrogen availability remains challenging due to catalyst deactivation, excessive cracking, and poor process stability. Palm acid oil (PAO), characterized by extremely high free fatty acid content, represents a particularly demanding feedstock. This study proposes a hydrogen-lean two-stage upgrading strategy that decouples acid value (AV) reduction from hydrocarbon formation through staged reactor operation. In the first stage, batch pretreatment under low hydrogen pressure (initial 0.1 MPa) enabled rapid apparent AV reduction. However, increasing temperature promoted thermally driven degradation, highlighting intrinsic limitations of single-stage severity intensification. Methanol-assisted pretreatment further decreased AV mainly through esterification and formation of oxygenated intermediates. In the second stage, hydrogen-free fixed-bed upgrading over oxide-based catalysts exhibited a distinct operating window near 365 °C, where stable condensed liquid recoveries of 50–60 wt% were obtained. Deoxygenation proceeded predominantly via decarbonylation/decarboxylation pathways. Among the catalysts investigated, ZrO₂–Co showed superior stability and lower residual AV. Overall, reactor staging enabled AV reductions exceeding 90% within 1.5–2 h while maintaining stable liquid recovery, demonstrating an effective upgrading strategy for highly acidic waste lipids under hydrogen-lean conditions. en-copyright= kn-copyright= en-aut-name=NogeHirofumi en-aut-sei=Noge en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UenoYoshie en-aut-sei=Ueno en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YahyaWira Jazair en-aut-sei=Yahya en-aut-mei=Wira Jazair kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Abd KadirHasannuddin en-aut-sei=Abd Kadir en-aut-mei=Hasannuddin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasunagaSachi en-aut-sei=Masunaga en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate school of education, Okayama university kn-affil= affil-num=2 en-affil=Department of comprehensive technical solutions, Okayama University kn-affil= affil-num=3 en-affil=Department of Food and Nutrition, Faculty of Home Economics, Kyoto Women's University kn-affil= affil-num=4 en-affil=Institute for Sustainable Transport HICoE, University Teknologi Malaysia kn-affil= affil-num=5 en-affil=Faculty of Mechanical Engineering, Universiti Teknologi MARA kn-affil= affil-num=6 en-affil=Department of comprehensive technical solutions, Okayama University kn-affil= en-keyword=Palm acid oil kn-keyword=Palm acid oil en-keyword=Two-stage upgrading kn-keyword=Two-stage upgrading en-keyword=Hydrogen-lean deoxygenation kn-keyword=Hydrogen-lean deoxygenation en-keyword=Fixed-bed reactor kn-keyword=Fixed-bed reactor en-keyword=Acid value reduction kn-keyword=Acid value reduction END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue= article-no= start-page=114910 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optical spectroscopic evaluation on the acquisition of optimal sonication temperature for efficient liquid phase exfoliation of molybdenum disulfide en-subtitle= kn-subtitle= en-abstract= kn-abstract=This work investigates how the sonication temperature affects the liquid phase exfoliation of MoS₂ using optical and morphological approach in attempt to acquire an optimal temperature for such process at ambient room conditions. In an ultrasonic bath, exfoliation was carried out at six different temperatures. UV-Vis, FTIR, Raman spectroscopy and SEM characterizations reveal that moderate room temperature range yield excellent results producing well-dispersed flakes with strong excitonic properties with mild oxidation. Higher temperatures cause substantial oxidation, deterioration and restacking while lower temperatures led to insufficient exfoliation and fragmented morphologies because of insufficient cavitation energy. The findings highlight the importance of temperature control in producing high quality nanosheets for scalable applications. en-copyright= kn-copyright= en-aut-name=AbdullahFatimah Az-Zahra Saravanan binti en-aut-sei=Abdullah en-aut-mei=Fatimah Az-Zahra Saravanan binti kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LeeWengnam en-aut-sei=Lee en-aut-mei=Wengnam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ÖhbergPatrik en-aut-sei=Öhberg en-aut-mei=Patrik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GohBoontong en-aut-sei=Goh en-aut-mei=Boontong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChongWuyi en-aut-sei=Chong en-aut-mei=Wuyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AhmadHarith en-aut-sei=Ahmad en-aut-mei=Harith kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayashiYasuhiko en-aut-sei=Hayashi en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishikawaTakeshi en-aut-sei=Nishikawa en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YapYuenkiat en-aut-sei=Yap en-aut-mei=Yuenkiat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=School of Engineering and Physical Sciences, Heriot-Watt University Malaysia kn-affil= affil-num=2 en-affil=Foundation Center, Heriot-Watt University Malaysia kn-affil= affil-num=3 en-affil=Institute of Photonics and Quantum Sciences, School of Engineering and Physical Sciences, Heriot-Watt University kn-affil= affil-num=4 en-affil=Low Dimensional Materials Research Center, Department of Physics, Faculty of Science, University of Malaya kn-affil= affil-num=5 en-affil=Photonics Research Center, University of Malaya kn-affil= affil-num=6 en-affil=Photonics Research Center, University of Malaya kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Foundation Center, Heriot-Watt University Malaysia kn-affil= en-keyword=MoS2 kn-keyword=MoS2 en-keyword=Liquid phase exfoliation kn-keyword=Liquid phase exfoliation en-keyword=Cavitation kn-keyword=Cavitation en-keyword=Oxidation kn-keyword=Oxidation END start-ver=1.4 cd-journal=joma no-vol=99 cd-vols= no-issue=6 article-no= start-page=uoag070 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260529 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of boranils by iodide-mediated demethylative borylation and their properties en-subtitle= kn-subtitle= en-abstract= kn-abstract=Boranils, difluoroboron complexes with imine and phenoxy moieties, were synthesized by iodide-promoted demethylative borylation.

The Malili Lake system on Sulawesi Island represents a classic natural laboratory for studying freshwater fish evolution and harbors multiple endemic Oryzias species that diversified under repeated hydrological reorganizations. Previous genomic analyses inferred that two sympatric species in Lake Towuti (O. profundicola and O. loxolepis) experienced a single ancient introgression event from a “ghost lineage” derived from O. marmoratus inhabiting another lake. However, recent taxonomic re-evaluation has revealed the presence of an extant O. marmoratus population within Lake Towuti itself. This finding suggests that the putative ghost lineage may in fact represent a living population co-occurring in the lake, calling for a re-examination of the introgression history and speciation mode in Lake Towuti.
Results By incorporating newly generated ddRAD-seq data from the true O. marmoratus in Lake Towuti, we reanalyzed phylogenetic relationships and population genetic structure among Malili Lake Oryzias. Previously reported major phylogenetic relationships and inter-lake introgression patterns were largely reproduced. In contrast, TreeMix and f4-statistic analyses revealed that introgression signals previously attributed to a “ghost lineage” into O. profundicola and O. loxolepis instead originated from the extant O. marmoratus population coexisting within Lake Towuti. Demographic model comparisons explicitly incorporating within-lake gene flow further supported a scenario in which O. profundicola and O. loxolepis diverged in allopatry, subsequently came into secondary contact within Lake Towuti, and later experienced additional gene flow following secondary contact with O. marmoratus that entered the lake.
Conclusion Our results demonstrate that introgression from the O. marmoratus lineage into O. profundicola and O. loxolepis was not a single ancient event, but rather a more sustained process. This finding highlights the critical importance of taxonomic resolution for accurately inferring introgression and divergence history. Comparative studies across other ancient lakes on Sulawesi will be valuable for understanding how the timing and nature of gene flow from third lineages influence patterns of population divergence and the strength of reproductive isolation. en-copyright= kn-copyright= en-aut-name=YashimaYuki en-aut-sei=Yashima en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NofriantoAndy B. en-aut-sei=Nofrianto en-aut-mei=Andy B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NuryadiHandung en-aut-sei=Nuryadi en-aut-mei=Handung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakiokaRyo en-aut-sei=Kakioka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHirozumi en-aut-sei=Kobayashi en-aut-mei=Hirozumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MandagiIxchel F. en-aut-sei=Mandagi en-aut-mei=Ixchel F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MasengiKawilarang W.

Field programmable gate arrays have numerous general-purpose programmable wires based on switching matrices to connect the outputs and inputs of look-up tables and input–output ports. However, field programmable gate arrays never use numerous general-purpose programmable wires for their clock distributions to satisfy the clock skew margin similarly to very large scale integrations. Field programmable gate arrays also use dedicated clock trees, although their programmability is not high. Currently, field programmable gate arrays can support multiple dedicated clock routing or multiple clock trees. Unfortunately, the number of clock trees is fixed. They remain limited to a small number. Even if an application requires many clock distributions, such a clock distribution cannot be supported in current field programmable gate arrays. This paper therefore presents a proposal of a more flexible clock distribution method based on wiring channels and switching matrices. The method uses general-purpose programmable wires. In addition, to resolve clock skew increase difficulties, we have introduced a new flip-flop with a two-phase clock signal. This paper presents simulation results obtained using the proposed clock distribution method on an originally designed field programmable gate array. In addition, experimentally obtained results indicate that the proposed clock distribution method can function correctly on a Cyclone V field programmable gate array. en-copyright= kn-copyright= en-aut-name=OguraAyumu en-aut-sei=Ogura en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeMinoru en-aut-sei=Watanabe en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeNobuya en-aut-sei=Watanabe en-aut-mei=Nobuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= en-keyword=Clock distribution kn-keyword=Clock distribution en-keyword=field programmable gate array (FPGA) kn-keyword=field programmable gate array (FPGA) en-keyword=programmable device kn-keyword=programmable device en-keyword=two-phase clock kn-keyword=two-phase clock END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=3 article-no= start-page=496 end-page=502 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bortezomib Induces Apoptosis via Upregulation of Abhd4 in Peripheral Nerve Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bortezomib, a first-in-class proteasome inhibitor, is widely used to treat multiple myeloma and other hematological malignancies. Despite its therapeutic efficacy, bortezomib causes peripheral neuropathy (PN) in approximately 20–30% of patients, often leading to dose reduction or discontinuation. Preventive or therapeutic approaches to bortezomib-induced PN are currently unavailable, as its precise mechanism remains unclear. In this study, we compared the effects of bortezomib and the second-generation proteasome inhibitor carfilzomib on peripheral nerve cells to identify candidate molecules involved in PN development. Transcriptome profiling of differentiated F11 cells, a hybridoma of a rat embryonic dorsal root ganglion and mouse neuroblastoma cell line N18TG2, revealed that bortezomib selectively upregulated α/β-hydrolase containing domain 4 (Abhd4), whereas carfilzomib did not. This finding was confirmed by quantitative RT-PCR and immunoblotting, which demonstrated consistent increases in Abhd4 mRNA and protein levels following bortezomib treatment. Functional analysis further revealed that Abhd4 overexpression promoted early apoptosis, suggesting a mechanistic link between bortezomib-induced Abhd4 elevation and neuronal vulnerability. Therefore, these results suggest that Abhd4 represents a candidate molecular signature associated with bortezomib-induced PN. Although further in vivo validation is needed, these findings warrant further investigation of Abhd4 as a potential contributor to bortezomib-induced PN. en-copyright= kn-copyright= en-aut-name=KonishiYusuke en-aut-sei=Konishi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmuraTomohiro en-aut-sei=Omura en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IjichiTakeshi en-aut-sei=Ijichi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiguchiHiroki en-aut-sei=Nishiguchi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayakawaRyunosuke en-aut-sei=Hayakawa en-aut-mei=Ryunosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitahiroYumi en-aut-sei=Kitahiro en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoharaKotaro en-aut-sei=Itohara en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoKazuhiro en-aut-sei=Yamamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanoIkuko en-aut-sei=Yano en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=2 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=5 en-affil=Education and Research Center for Clinical Pharmacy, Kobe Pharmaceutical University kn-affil= affil-num=6 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=8 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= en-keyword=bortezomib kn-keyword=bortezomib en-keyword=carfilzomib kn-keyword=carfilzomib en-keyword=peripheral neuropathy kn-keyword=peripheral neuropathy en-keyword=multiple myeloma kn-keyword=multiple myeloma en-keyword=proteasome inhibitor kn-keyword=proteasome inhibitor END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=4 article-no= start-page=896 end-page=903 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of TIF1β in Leukemic Stem Cell Through SETDB1-Dependent and Independent Mechanisms en-subtitle= kn-subtitle= en-abstract= kn-abstract=TIF1β/TRIM28/KAP1 has been recognized as a scaffold protein that partners with KRAB-ZFPs and heterochromatin complexes to enforce gene silencing. In embryonic and pluripotent stem cells, it maintains self-renewal by silencing endogenous retroelements through the establishment of heterochromatin. While these canonical functions have been extensively examined in embryonic stem (ES) cells, accumulating evidence also highlights its diverse contributions to cancer biology. We herein focused on the oncogenic role of TIF1β in leukemic progression, contrasting this with its physiological roles in hematopoietic stem cell maintenance, differentiation, and immune regulation, thereby providing a comparative perspective on H3K9 methyltransferase SETDB1-dependent and -independent mechanisms. TIF1β-mediated epigenetic plasticity was recently shown to establish a leukemic chromatin environment for promoting oncogenic transcriptional programs while repressing lineage-differentiation regulators, which drives leukemic progression in a context-dependent manner. This review summarizes the dual role of TIF1β as a chromatin modulator, functioning both as a canonical transcriptional co-repressor and as a context-dependent co-activator, and also discusses how these modalities cooperate to sustain leukemic stem cell programs. en-copyright= kn-copyright= en-aut-name=MoriiMariko en-aut-sei=Morii en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SashidaGoro en-aut-sei=Sashida en-aut-mei=Goro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Transcriptional Regulation in Leukemogenesis, International Research Center for Medical Sciences, Kumamoto University kn-affil= en-keyword=BCR::ABL1 kn-keyword=BCR::ABL1 en-keyword=hematopoiesis kn-keyword=hematopoiesis en-keyword=heterochromatin kn-keyword=heterochromatin en-keyword=leukemia kn-keyword=leukemia en-keyword=transcription kn-keyword=transcription END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=1 article-no= start-page=407 end-page=414 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Polymeric Formula on Outcomes in Robotic Pancreatectomy: A Randomized Controlled Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Evidence regarding the benefits of nutritional therapy after robotic pancreatectomy is limited. This randomized controlled trial aimed to investigate the effects of a polymeric formula (PF) on preventing body weight loss (BWL) following robotic pancreatectomy.
Patients and Methods: This single-center, open-label, randomized trial was conducted to assign 46 patients undergoing robotic pancreatectomy in a 1:1 ratio to either the PF (ISOCAL Clear) or control group. The primary endpoint was the percentage of BWL on postoperative days 14 and 28. The secondary endpoints were postoperative outcomes.
Results: Of the 52 eligible patients between December 2023 and November 2024, 46 were analyzed using intention-to-treat principles: 23 in the ISOCAL group and 23 in the control group. The %BWL was significantly lower in the ISOCAL group compared with that in the control group on postoperative days 14 (4.8±3.5% vs. 6.6±3.2%, p=0.02) and 28 (6.4±3.0% vs. 8.4±3.5%, p=0.047). Postoperative outcomes, including major complications (p=0.55) and hospital stay (p=0.83), did not differ significantly between the groups.
Conclusion: This study demonstrates the safety and feasibility of administering PF to patients undergoing robotic pancreatectomy. The results showed the beneficial effects of PF on mitigating BWL without compromising short-term outcomes. en-copyright= kn-copyright= en-aut-name=TAKAGIKOSEI en-aut-sei=TAKAGI en-aut-mei=KOSEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FUJITOMOKAZU en-aut-sei=FUJI en-aut-mei=TOMOKAZU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YASUIKAZUYA en-aut-sei=YASUI en-aut-mei=KAZUYA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YAMADAMOTOHIKO en-aut-sei=YAMADA en-aut-mei=MOTOHIKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NISHIYAMATAKEYOSHI en-aut-sei=NISHIYAMA en-aut-mei=TAKEYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NAGAIYASUO en-aut-sei=NAGAI en-aut-mei=YASUO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HASHIMOTOMASASHI en-aut-sei=HASHIMOTO en-aut-mei=MASASHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MITSUHASHITOSHIHARU en-aut-sei=MITSUHASHI en-aut-mei=TOSHIHARU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FUJIWARATOSHIYOSHI en-aut-sei=FUJIWARA en-aut-mei=TOSHIYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Robotic pancreatectomy kn-keyword=Robotic pancreatectomy en-keyword=nutrition kn-keyword=nutrition en-keyword=polymeric formula kn-keyword=polymeric formula en-keyword=outcomes kn-keyword=outcomes END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=3 article-no= start-page=643 end-page=650 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=Post Hoc Analysis of Frailty and Tracheostomy Risk in Older Patients Intubated and in an Intensive Care Unit in Japan: An Inverse Association in Older Patients with Advanced Age en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: This post hoc analysis of a prospectively collected intensive care unit (ICU) cohort examined the association between frailty and the likelihood of tracheostomy in older Japanese patients (aged ≥65 years). Frailty, a condition of increased vulnerability to stressors, is common among older patients in the ICU and may influence clinical decision-making and outcomes. We aimed to explore whether baseline frailty is associated with the likelihood of receiving tracheostomy in older patients in the ICUs.
Methods: We analyzed data from a multicenter prospective study conducted from November 2019 to April 2020 at 17 hospitals in Japan. Patients aged ≥65 years, admitted directly from the emergency department, and requiring mechanical ventilation, were included. After excluding early deaths (≤5 days) or treatment-limit cases, 363 patients with intubation remained. Frailty was assessed using the Clinical Frailty Scale (CFS), with primary cutoff CFS ≥4. The primary outcome was the occurrence of tracheostomy during ICU stay. Risk ratios (RRs) and 95% confidence intervals (CIs) were estimated using generalized linear models with a Poisson distribution, adjusted for age, sex, Charlson Comorbidity Index, and Acute Physiology and Chronic Health Evaluation II score.
Results: Among 363 patients, patients with frailty (CFS ≥4) had a significantly lower adjusted risk of having tracheostomy than did those with less frailty (CFS <4) (adjusted RR: 0.40; 95% CI: 0.27-0.61). In patients aged ≥75 years, the adjusted RR for CFS ≥4 was 0.32 (95% CI: 0.20-0.50), indicating a pronounced reduction in tracheostomy use among patients with frailty.
Conclusions: Frailty (CFS ≥4) was independently associated with a lower likelihood of tracheostomy, particularly in patients aged ≥75 years. en-copyright= kn-copyright= en-aut-name=UmedaTakehide en-aut-sei=Umeda en-aut-mei=Takehide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InabaMototaka en-aut-sei=Inaba en-aut-mei=Mototaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=AriyasuYoshinori en-aut-sei=Ariyasu en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=frailty kn-keyword=frailty en-keyword=respiration kn-keyword=respiration en-keyword=tracheostomy kn-keyword=tracheostomy en-keyword=critical care outcomes kn-keyword=critical care outcomes en-keyword=aged kn-keyword=aged END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=5 article-no= start-page=e70314 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Survey to Document the Adverse Reactions After Human Papillomavirus Vaccination Among Japanese Female Youth at a University en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Concerns about possible adverse events remain a critical barrier in implementing human papillomavirus (HPV) vaccination among Japanese youth. This study aimed to understand the time course of adverse events experienced by HPV vaccine recipients.
Methods: An online questionnaire survey was given to students, faculty, and staff aged 18–26 years, at Okayama University Hospital, who received the HPV vaccine. The survey gathered information on the number of HPV vaccine doses received, prevaccination health conditions, adverse reactions within 2 h and between 2 h and 7 days postvaccination, menstrual irregularities after vaccination, reasons for getting vaccinated, feelings before and after vaccination, and factors providing reassurance during vaccination. Prevalence of symptoms was expressed as numbers and percentages, and analyses were performed using Chi-squared or Fisher's exact tests.
Results: Responses were obtained from 299 participants, yielding a 75% response rate. Approximately 60% participants reported local pain, 30% swelling, and 4% fever. Most symptoms resolved on the vaccination day itself or the following day, although some persisted for 3–7 days. Over 80% participants rated their pain between 0 and 3 on numerical rating scale of 0–10. While 60% experienced anxiety before vaccination, 90% reported no anxiety afterward.
Conclusions: Our study presents one of the first comprehensive accounts of post-HPV vaccination adverse events and their time course, and underpins the importance of disseminating detailed information about vaccine-associated adverse reactions to encourage greater vaccine uptake. en-copyright= kn-copyright= en-aut-name=HiguchiChigusa en-aut-sei=Higuchi en-aut-mei=Chigusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaChikako en-aut-sei=Ogawa en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwasakiYoshiaki en-aut-sei=Iwasaki en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Educational and Research Management Field, Health Management Department, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=1Educational and Research Management Field, Health Management Department, Okayama University kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=human papillomavirus vaccine kn-keyword=human papillomavirus vaccine en-keyword=Japanese youth kn-keyword=Japanese youth en-keyword=questionnaire kn-keyword=questionnaire en-keyword=survey kn-keyword=survey END start-ver=1.4 cd-journal=joma no-vol=368 cd-vols= no-issue=12 article-no= start-page=e70571 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of Aromatic Aldehydes by C─H Formylation of Aromatics with Silyl Formates Prepared from CO2 and Hydrosilanes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite the recent remarkable progress in CO2 fixation reactions, the methods for the synthesis of aldehydes from CO2 are quite limited partly because of the lability of the resulting formyl group and difficulty in the controlled deoxygenative CO2 conversions leading to C─H and C─C bond formation. Here, we have developed the direct C─H formylation of electron-rich aromatics using silyl formates, prepared from CO2 and hydrosilanes, in the presence of BCl3 or BBr3. This is the first report on the direct C─H formylation of aromatics with silyl formates. Useful compounds including a biologically active compound and octaethylporphyrin were synthesized by fixing one to four CO2 molecules in a stepwise manner. DFT calculations have been done to elucidate the reaction mechanism including a dual role of BBr3 in the activation of silyl formate, HCO2SiMe2Ph, and electrophilic aromatic substitution. en-copyright= kn-copyright= en-aut-name=NittaNatsumi en-aut-sei=Nitta en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirokawaKei en-aut-sei=Hirokawa en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaibaraSo en-aut-sei=Saibara en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NathBikash Dev en-aut-sei=Nath en-aut-mei=Bikash Dev kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaishiKazuto en-aut-sei=Takaishi en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=aldehydes kn-keyword=aldehydes en-keyword=carbon dioxide fixation kn-keyword=carbon dioxide fixation en-keyword=CO2 reduction kn-keyword=CO2 reduction en-keyword=formylation kn-keyword=formylation en-keyword=hydrosilylation kn-keyword=hydrosilylation END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=3 article-no= start-page=e105091 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Septic Arthritis of the Temporomandibular Joint Complicated by Dislocation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Septic arthritis of the temporomandibular joint (SATMJ) is a rare but potentially serious condition, and standardized diagnostic and therapeutic strategies have not been established. We present the case of a 70-year-old man who developed acute right temporomandibular joint (TMJ) pain, swelling, mandibular deviation, and inability to achieve mouth closure. Computed tomography and magnetic resonance imaging revealed right TMJ dislocation, joint effusion, degenerative changes, and anterior disc displacement with effusion. Aspiration of the joint yielded neutrophil-predominant purulent fluid, although bacterial cultures were negative. The patient was treated empirically with intravenous ceftriaxone followed by oral clindamycin and amoxicillin, resulting in rapid symptom resolution, and the dislocation spontaneously reduced without surgical intervention. No recurrence was observed during three months of follow-up. This case highlights the diagnostic challenges associated with culture-negative SATMJ, supports the role of early empirical antibiotic therapy, and suggests that chronic joint instability due to habitual dislocation may predispose the TMJ to infection. en-copyright= kn-copyright= en-aut-name=KanemotoHideka en-aut-sei=Kanemoto en-aut-mei=Hideka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataKyoichi en-aut-sei=Obata en-aut-mei=Kyoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= affil-num=1 en-affil=Department of Oral Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine kn-affil= en-keyword=antibiotics kn-keyword=antibiotics en-keyword=culture-negative infection kn-keyword=culture-negative infection en-keyword=joint dislocation kn-keyword=joint dislocation en-keyword=septic arthritis kn-keyword=septic arthritis en-keyword=temporomandibular joint kn-keyword=temporomandibular joint END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=3 article-no= start-page=e70128 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness and Safety of Enteroscopy-Assisted ERP-Guided Versus EUS-Guided Pancreatic Duct Drainage for Pancreaticojejunostomy Strictures: A Multicenter Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Enteroscopy-assisted endoscopic retrograde pancreatography-guided pancreatic duct drainage (eERP-PDD) and endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD) are minimally invasive alternatives to surgery for pancreaticojejunostomy stricture (PJS); however, comparative data remain limited. We compared the effectiveness and safety of these approaches and identified factors associated with technical failure.
Methods: This multicenter retrospective study included 88 patients (111 procedures) who underwent endoscopic intervention for PJS at 13 Japanese tertiary centers. We compared clinical outcomes between eERP-PDD and EUS-PDD. The primary outcome was technical success; secondary outcomes included clinical success, procedure time, and adverse events (AEs). Propensity-score overlap weighting was used to adjust for baseline differences.
Results: As initial treatment, 77 patients underwent eERP-PDD and 11 underwent EUS-PDD. After adjustment, EUS-PDD achieved higher technical success (eERP-PDD, 28% vs. EUS-PDD, 71%; p = 0.012) and clinical success (22% vs. 71%; p = 0.003), with shorter procedure time (76 min vs. 41 min; p = 0.001). AE incidence was higher with EUS-PDD before adjustment (5% vs. 27%; p = 0.039) but comparable after adjustment (7% vs. 29%; p = 0.15); all AEs resolved with conservative management. Age < 75 years, male sex, and main pancreatic duct (MPD) diameter ≥ 5 mm were independently associated with eERP-PDD failure.
Conclusions: EUS-PDD demonstrated higher technical and clinical success than eERP-PDD for PJS, with comparable safety after adjustment. An MPD diameter ≥ 5 mm was associated with eERP-PDD failure. An MPD-based algorithm is proposed: eERP-PDD for MPD < 5 mm with EUS-PDD as salvage, and EUS-PDD for MPD ≥ 5 mm. This algorithm is hypothesis-generating and requires prospective validation. en-copyright= kn-copyright= en-aut-name=OtaShogo en-aut-sei=Ota en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei=

infectious diseases: A narrative review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Asynchronous electronic consultation, eConsult, is increasingly applied in infectious diseases (ID) management to improve access to specialty care and reduce unnecessary referrals. We aimed to integrate published studies to provide a comparative perspective and propose future directions for ID eConsult.
Methods: To synthesize relevant findings and present a comprehensive overview of ID eConsult, we searched in MEDLINE database and identified 11 studies between 2017 and 2025 on ID eConsult programs. Structured data were extracted on study characteristics, mode of consultation, and outcomes.
Results: Nine studies on outpatient ID eConsult demonstrated faster turnaround times, high rates of avoidance of in-person referrals (24-87%), improved antimicrobial optimization, and high provider satisfaction. Two studies on inpatient ID eConsult reported reductions in mortality, readmission rates, and broad-spectrum antibiotic use.
Conclusions: Given its affordability and scalability, the ID eConsult model is particularly advantageous in resource-limited environments. Collectively, ID eConsult may replace traditional telephone or face-to-face consultations, reducing the need for informal curbside discussions. 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=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamotoKenta en-aut-sei=Nakamoto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Electronic consultation (eConsult) kn-keyword=Electronic consultation (eConsult) en-keyword=Telehealth kn-keyword=Telehealth en-keyword=Infectious diseases kn-keyword=Infectious diseases en-keyword=Antimicrobial stewardship kn-keyword=Antimicrobial stewardship en-keyword=Primary care kn-keyword=Primary care en-keyword=Remote consultation kn-keyword=Remote consultation END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=121 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immunological effects of amivantamab in EGFR or MET-expressing non-small cell lung cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Epidermal growth factor receptor (EGFR) mutations represent one of the most frequent oncogenic driver in non-small cell lung cancer (NSCLC). Amivantamab, a bispecific antibody targeting EGFR and MET proto-oncogene, receptor tyrosine kinase (MET), has demonstrated clinical benefit in EGFR-mutant NSCLC through dual blockade, but its immunological role in human clinical specimens, especially tumor-infiltrating lymphocytes (TILs), has not been directly evaluated.
Methods We analyzed surgically resected tumor samples from 40 patients with NSCLC to investigate immune responses and their associations with EGFR and MET expression. TILs were characterized by flow cytometry (FCM) and immunohistochemistry (IHC). To assess the immunomodulatory potential of amivantamab, fresh tumor digests containing live tumor cells and TILs were cultured ex vivo with CD3 and CD28 stimulation in the absence or presence of amivantamab, followed by FCM. EGFR and MET expression were also evaluated by IHC.
Results EGFR mutations and high EGFR protein expression were associated with a trend toward reduced CD8⁺ T-cell and dendritic cell (DC) infiltration. In ex vivo TIL assays, exposure to amivantamab significantly activated CD8⁺ T cells, such as programmed cell death-1 expression and cytokine production, and promoted DC maturation. These effects were most pronounced in tumors with high EGFR or MET protein expression rather than EGFR mutations.
Conclusions This study provides the first direct evidence from ex vivo fresh TIL assays using human NSCLC clinical specimens that amivantamab can activate immune responses. EGFR and MET expression may serve as potential biomarkers for amivantamab-induced immune responses. en-copyright= kn-copyright= en-aut-name=YoshichikaRyo en-aut-sei=Yoshichika en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MukoharaFumiaki en-aut-sei=Mukohara en-aut-mei=Fumiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKotaro en-aut-sei=Yamada en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeHiroko en-aut-sei=Watanabe en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshinoTakamasa en-aut-sei=Ishino en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Okayama University kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Okayama University kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Okayama University kn-affil= affil-num=10 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Non-small cell lung cancer kn-keyword=Non-small cell lung cancer en-keyword=Amivantamab kn-keyword=Amivantamab en-keyword=Antitumor immunity kn-keyword=Antitumor immunity en-keyword=EGFR kn-keyword=EGFR en-keyword=MET kn-keyword=MET END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=3 article-no= start-page=100926 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Potential Immune Microenvironment Biomarkers in SCLC: J-TAIL-2 Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Effective predictors of response to atezolizumab plus carboplatin/etoposide (CE) therapy in extensive-stage SCLC (ES-SCLC) remain limited. This exploratory analysis from J-TAIL-2 aimed to identify markers of survival benefit with atezolizumab plus CE therapy in ES-SCLC.
Methods: J-TAIL-2 (ClinicalTrials.gov ID, NCT04501497) was a multicenter observational study that enrolled patients receiving atezolizumab plus CE (ES-SCLC cohort) in clinical practice in Japan per local label and treatment guidelines. In this exploratory analysis, the association of CD8+ tumor-infiltrating lymphocyte (TIL) density and SCLC subtypes (SCLC-A [ASCL1 dominant], SCLC-N [NEUROD1 dominant], SCLC-P [ASCL1/NEUROD1 double-negative with POU2F3 expression], and SCLC-O [ASCL1/NEUROD1 double-negative not otherwise specified]) with overall survival (OS) and progression-free survival (PFS) was evaluated. SCLC subtyping was performed by immunohistochemistry.
Results: SCLC samples (n = 100; data cutoff, February 3, 2023) were categorized as SCLC-A (73%), SCLC-N (16%), SCLC-P (8%), and SCLC-O (3%). Among 96 patients who received first-line atezolizumab plus CE, median age was 72 (range, 39–87) years and 81% were male. Furthermore, 56 patients were classified into the CD8+ TIL-high subgroup and 40 into the TIL-low subgroup. Median (m)PFS with atezolizumab plus CE was 6.1 months (95% confidence interval [CI]: 4.5–7.5) in the TIL-high versus 4.4 months (95% CI: 4.0–5.1) in the TIL-low subgroup (p = 0.01); mOS was 18.4 (95% CI: 11.8–not estimable) versus 10.8 months (95% CI: 7.7–16.2; p = 0.04). mOS and mPFS were not significantly different between SCLC subtypes but were numerically shorter in the SCLC-N group.
Conclusions: CD8+ TIL density is a potential biomarker of clinical benefit in ES-SCLC and may facilitate patient selection for atezolizumab combination therapy. en-copyright= kn-copyright=

Potentiates Osimertinib-Induced Anti-Tumor Immunity in Egfr-Mutant Lung Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunotherapy for epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) remains challenging. We previously found that EGFR-tyrosine kinase inhibitors induced antitumor immunity but also triggered immunosuppressive cytokines, including transforming growth factor-β (TGF-β), in Egfr-mutant lung cancer. Here, we investigate whether TGF-β inhibition potentiates osimertinib-induced antitumor immunity using a syngeneic mouse model of Egfr-mutated lung cancer, with cancer cells subcutaneously transplanted into wild-type C57BL/6J mice. We evaluated the antitumor effect of the combination therapy with osimertinib and either nintedanib (an indirect TGF-β inhibitor) or vactosertib (a specific TGF-β type I receptor kinase inhibitor). Changes in the tumor microenvironment during treatment were assessed using immunohistochemical staining, western blot analysis, and flow cytometry. We found that TGF-β expression was upregulated in the tumor treated with osimertinib. Nintedanib monotherapy showed no significant antitumor effect, whereas osimertinib combined with nintedanib significantly potentiates the antitumor effect compared with osimertinib monotherapy in vivo. Crucially, no additive effect of nintedanib on osimertinib monotherapy was observed in vitro. Combination therapy with osimertinib and nintedanib significantly increased effector T cells (CD8+CD44+CD62L−) and Granzyme B+ areas and decreased CD206+ cells, while significantly decreasing TGF-β and SMAD2/3 expression. Similar effects were observed with vactosertib but not with a vascular endothelial growth factor receptor 2 inhibitor. In conclusion, combination therapy with osimertinib and TGF-β inhibitors potentiates osimertinib-induced antitumor immunity. These findings highlight a novel therapeutic strategy for EGFR-mutated NSCLC and warrant further clinical investigation. en-copyright= kn-copyright= en-aut-name=KuribayashiTadahiro

kn-article= en-subject= kn-subject= en-title= kn-title=Pseudoaneurysm of the thoracoacromial artery associated with habitual shoulder dislocation: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Shoulder dislocation is one of the most common joint dislocations encountered in emergency departments, but vascular complications are rare and often underrecognized. Pseudoaneurysms of the thoracoacromial artery, a branch of the axillary artery, are extremely uncommon and may present with subtle symptoms, delaying diagnosis.
Case presentation An 82-year-old woman with a history of habitual anterior shoulder dislocation presented with a 10-day history of progressive pain and swelling in the left shoulder. She was on edoxaban for atrial fibrillation. Examination revealed localized tenderness and swelling without neurological deficits. Computed tomography angiography showed a 30 × 35 × 35 mm pseudoaneurysm arising from the acromial branch of the thoracoacromial artery. Endovascular embolization was performed using a proximal oxidized regenerated cellulose sheet placement followed by injection of N-butyl cyanoacrylate and Lipiodol due to the risk of coil migration into the joint space. The procedure achieved complete exclusion of the lesion. At three-month follow-up, the patient remained asymptomatic with preserved left upper limb function. Computed tomography angiography demonstrated the pseudoaneurysm remains excluded.
Conclusion Although rare, pseudoaneurysms of the thoracoacromial artery can occur after repeated shoulder dislocation and reduction, especially in elderly patients on anticoagulation therapy. Early recognition through imaging and prompt endovascular intervention can prevent serious vascular and neurological complications. en-copyright= kn-copyright= en-aut-name=WadaHonoka en-aut-sei=Wada en-aut-mei=Honoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamasakiAya en-aut-sei=Hamasaki en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoSoichiro en-aut-sei=Okamoto en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoShunki en-aut-sei=Yamamoto en-aut-mei=Shunki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Pseudoaneurysm kn-keyword=Pseudoaneurysm en-keyword=Thoracoacromial artery kn-keyword=Thoracoacromial artery en-keyword=Shoulder dislocation kn-keyword=Shoulder dislocation en-keyword=Anticoagulation kn-keyword=Anticoagulation en-keyword=Endovascular embolization kn-keyword=Endovascular embolization END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=329 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-risk soft-tissue sarcomas in elderly patients: does perioperative radiotherapy improve local control and prognosis? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Accumulating evidence suggests that advanced age is associated with poor local control and prognosis in patients with soft-tissue sarcomas (STSs), highlighting the need to optimise treatment for this age group. However, real-world data on treatment details and outcomes in elderly patients are limited. This study aimed to clarify the role of perioperative radiotherapy (RT) for treating high-risk STSs in elderly patients.
Methods Patients aged ≥ 70 years who underwent surgery for localised, high-grade, deep-seated non-small round cell STSs measuring ≥ 5 cm were included in the Bone and Soft Tissue Tumour Registry in Japan. Patients with small-round cell STSs or myxoid liposarcomas, or those who received perioperative chemotherapy or intraoperative RT, were excluded.
Results Among the 1,214 patients who met the criteria, 47 (4%), 219 (18%), and 2 (0.2%) received neoadjuvant, adjuvant, and both neoadjuvant and adjuvant RT, respectively. The 5- and 10-year disease-specific survival (DSS) rates were 72.7% and 64.7%, respectively. Tumour size ≥ 10 cm, intralesional margin, and local recurrence were associated with poorer DSS; however, perioperative RT did not affect DSS. The 5- and 10-year cumulative probabilities of local recurrence (LR) were 14.6% and 19.5%, respectively. Trunk wall tumours, dedifferentiated liposarcomas, marginal margins, and intralesional margins were associated with a higher probability of LR. Adjuvant RT was associated with a reduced LR probability in patients with intralesional (p = 0.005) or marginal margins (p = 0.044); however, no such benefit was observed in patients with wide margins, who constituted the majority of the cohort, resulting in no significant association between perioperative RT and LR in overall analyses. In the propensity score-matched cohort, no significant differences in DSS or cumulative probability of LR were observed between patients with and without perioperative RT.
Conclusion Adjuvant RT was associated with reduced LR rates in elderly patients with high-risk STSs who had intralesional or marginal margins. However, because most patients achieved wide margins and no benefit of perioperative RT was observed in this group, RT was not associated with reduced LR or improved survival in the overall or propensity score–matched analyses. Prospective trials are warranted to define the role of perioperative RT in elderly patients with high-risk STSs. en-copyright= kn-copyright= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NezuYutaka en-aut-sei=Nezu en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TajimaTakashi en-aut-sei=Tajima en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiwaShinji en-aut-sei=Miwa en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KojimaToshio en-aut-sei=Kojima en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraShuichi en-aut-sei=Fujiwara en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiAkira en-aut-sei=Kawai en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaKazuhiro en-aut-sei=Tanaka en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Centre for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Yokohama City University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Kyorin University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Nihon University School of Medicine kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kobe University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Musculoskeletal Oncology, National Cancer Centre Hospital kn-affil= affil-num=9 en-affil=Department of Advanced Medical Sciences, Oita University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Soft-tissue sarcoma kn-keyword=Soft-tissue sarcoma en-keyword=High-risk kn-keyword=High-risk en-keyword=Surgery kn-keyword=Surgery en-keyword=Perioperative radiotherapy kn-keyword=Perioperative radiotherapy en-keyword=Elderly patients kn-keyword=Elderly patients END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=1612 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Community health worker-supported oral health promotion in low- and middle-income countries: a scoping review of roles, interventions, and outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Oral diseases are among the most prevalent conditions worldwide and disproportionately affect populations in low- and middle-income countries (LMICs). The shortage and maldistribution of the oral health workforce have widened inequalities in prevention and treatment. Task-sharing through community health workers (CHWs) has been promoted as a cost-effective and sustainable strategy for extending services to underserved populations; however, evidence on their roles in oral health promotion in LMICs remains fragmented. This scoping review mapped evidence on CHW-supported oral health promotion and identified common roles, interventions, and system-level challenges.
Methods A comprehensive search was conducted in PubMed, CINAHL, CENTRAL, and Google Scholar, using keywords and MeSH terms related to “community health workers,” “oral health,” and LMICs, based on the EPOC LMIC filter of the World Bank’s classifications. No publication date restrictions were applied, and gray literature was included. The review followed the Joanna Briggs Institute (JBI) methodology for scoping reviews and was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Data were charted on CHW characteristics, roles, target populations, oral conditions addressed, and implementation challenges, and synthesized narratively. This protocol was registered on Open Science Forum (https://doi.org/10.17605/OSF.IO/NZPHA).
Results Thirty-two studies from 11 LMICs were included, approximately half from India. The evidence mapped a wide range of CHW roles and interventions, most commonly focusing on oral cancer screening, followed by dental caries prevention and periodontal care. CHWs were involved in home visits, education, screening, basic treatment, and referrals. Some programs integrate mobile health (mHealth) tools for remote diagnosis. System-level challenges were variably reported across settings, including inadequate infrastructure, fragmented referral systems, limited supervision, and constrained career development opportunities for CHWs.
Conclusions This scoping review highlights the contributions of CHWs to oral health promotion in LMICs, while underscoring health system and workforce constraints. The available evidence is largely descriptive, suggesting the need for strengthened training, supervision, referral linkages, and career development to support CHWs’ integration into oral health services. Family-centered and Continuum of Care approaches warrant further exploration to inform equitable and sustainable oral health within primary health care systems. en-copyright= kn-copyright= en-aut-name=YasuokaJunko en-aut-sei=Yasuoka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Division of Global Health Sciences, Graduate School of Public Health, St. Luke’s International University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Medical Development Field, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Community health worker kn-keyword=Community health worker en-keyword=Oral health kn-keyword=Oral health en-keyword=Low- and middle-income countries kn-keyword=Low- and middle-income countries END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=12 article-no= start-page=2134 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Toward Convergence in Multi-Agent Reinforcement Learning: Best-Response Space Shrinking as a Sufficient Condition en-subtitle= kn-subtitle= en-abstract= kn-abstract=We study convergence in multi-agent reinforcement learning (MARL) through the lens of sufficient conditions, using a single-point-of-failure analysis applied to multi-agent policy iteration integrated with linear programming (MAPI-LP), where results are proven for pure coordination games, and extension to broader settings is conjectured. We identify two sufficient conditions for convergence to Markov Perfect Equilibrium (MPE). The first is stability in best-response space that emerges from value monotonicity. The second, monotonic best-response space shrinking (MBRSS), is a novel condition requiring that each agent’s best-response space contracts monotonically across iterations until it collapses to a stable space. Furthermore, we show that MBRSS does not necessarily imply monotonic improvement in this setting. However, value monotonicity and stability in best-response space imply each other when a complementary condition is applied. Building on this hierarchical relationship, we propose conjectures on sufficient condition relationships in both serial and parallel MARL. In addition, we propose conjectures on generalized MBRSS to arbitrary finite repeated games and validation of stability in best-response space. We further discuss connections between MBRSS and existing related frameworks, and outline directions toward a taxonomy of sufficient conditions for MARL convergence. en-copyright= kn-copyright= en-aut-name=ManatphaiboonNatchanon en-aut-sei=Manatphaiboon en-aut-mei=Natchanon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MondenAkito en-aut-sei=Monden en-aut-mei=Akito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YücelZeynep en-aut-sei=Yücel en-aut-mei=Zeynep 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=Department of Environmental Sciences, Informatics and Statistics, Ca’Foscari University of Venice kn-affil= en-keyword=sufficient condition kn-keyword=sufficient condition en-keyword=convergence analysis kn-keyword=convergence analysis en-keyword=Markov perfect equilibrium kn-keyword=Markov perfect equilibrium en-keyword=multi-agent reinforcement learning kn-keyword=multi-agent reinforcement learning en-keyword=best-response dynamics kn-keyword=best-response dynamics END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=2 article-no= start-page=832 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Possible Involvement of Hypothalamic Dysfunction in Long COVID Patients Characterized by Delayed Response to Gonadotropin-Releasing Hormone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Long COVID (LC) may involve endocrine dysfunction; however, the underlying mechanism remains unclear. To examine hypothalamic–pituitary responses in patients with LC, we conducted a single-center retrospective study of patients with refractory LC referred to our University Hospital who underwent anterior pituitary stimulation tests. Between February 2021 and November 2025, 1251 patients with long COVID were evaluated, of whom 207 (19%) had relatively low random ACTH or cortisol levels. Ultimately, 16 underwent anterior pituitary stimulation tests and were included. All tests were performed in an inpatient setting without exogenous steroids. Fifteen patients (six women, mean age 35.6 years) underwent corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH), and gonadotropin-releasing hormone (GnRH) tests. All patients had mild acute COVID-19, eight had ≥2 vaccinations, and the mean interval from infection was 343 days. Frequent symptoms included fatigue (100%), insomnia (66.7%), headache (60.0%), anorexia/nausea (40.0%), and brain fog (40.0%). Mean early-morning cortisol and 24 h urinary free cortisol were 7.5 μg/dL and 41.0 μg/day, respectively. MRI showed an empty sella in one case. Peak hormonal responses were preserved (ΔACTH 247%, ΔTSH 918%, ΔPRL 820%, ΔFSH 187%, ΔLH 1150%); however, peaks were delayed beyond 60 min in ACTH (13%), LH (33%), and FSH (87%). Notably, significantly delayed elevations remained at 120 min in the responses of TSH (4.1-fold), PRL (1.8-fold), LH (9.3-fold), and FSH (2.8-fold), suggesting possible hypothalamic involvement, particularly in the gonadotropin responses. Additionally, serum IGF-I was lowered (−0.70 SD), while GH response (mean peak 35.5 ng/mL) was preserved by growth hormone-releasing peptide (GHRP)-2 stimulation. Low-dose hydrocortisone and testosterone were initiated for three patients. Although direct viral effects and secondary suppression have been proposed, our findings may suggest that, at least in part, the observed response characteristics are consistent with functional secondary hypothalamic dysfunction rather than irreversible primary injury. These findings highlight the need for objective endocrine evaluation before initiating hormone replacements. en-copyright= kn-copyright= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki

kn-subtitle= en-abstract= kn-abstract=KRASG12C inhibitors, such as sotorasib, show clinical efficacy for non–small cell lung cancer (NSCLC) positive for the G12C mutations of KRAS, but primary and acquired resistance to these drugs remains a clinical problem. In this study, we show that the development of resistance to sotorasib in KRASG12C-positive NSCLC cells was mediated by constitutive activation of EGFR resulting from downregulation of the protein tyrosine phosphatase receptor type R (PTPRR). PTPRR has been identified as a physiologic regulator of ERK signaling in several cancer types. In our study, PTPRR was demonstrated to bind directly to EGFR, facilitating its dephosphorylation on tyrosine residues. Resumption of PTPRR expression in the resistant cells attenuated EGFR phosphorylation and restored sotorasib sensitivity. PTPRR downregulation was associated with gene promoter hypermethylation in the sotorasib-resistant cells and NSCLC tissue samples. Furthermore, low PTPRR expression in tumor specimens was associated with shorter progression-free and overall survival for patients with NSCLC treated with sotorasib. In contrast to sotorasib, high PTPRR expression was associated with a poor response to EGFR tyrosine kinase inhibitors in EGFR-mutated NSCLC, suggesting that PTPRR may broadly regulate EGFR dependence in NSCLC. Finally, dual blockade of KRASG12C and EGFR showed a substantial antitumor effect in a xenograft model of sotorasib-resistant NSCLC. This approach is therefore a rational therapeutic strategy for KRASG12C-positive NSCLC, especially for tumors showing PTPRR downregulation.
Significance: The current study shows that downregulation of PTPRR induces EGFR activation and resistance to KRASG12C inhibitors in NSCLC, suggesting dual KRAS-EGFR blockade as a rational therapy. PTPRR may help identify patient subgroups that would benefit from the addition of EGFR inhibitors to KRASG12C-targeted therapies. en-copyright= kn-copyright= en-aut-name=KanemuraHiroaki en-aut-sei=Kanemura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeharaToshiyuki en-aut-sei=Takehara en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaenishiOsamu en-aut-sei=Maenishi en-aut-mei=Osamu 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=IwawakiNatsumi en-aut-sei=Iwawaki en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KunimasaKei en-aut-sei=Kunimasa en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakayamaTomohiro en-aut-sei=Nakayama en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeSatomi en-aut-sei=Watanabe en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiShinichiro en-aut-sei=Suzuki en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaiKazuko en-aut-sei=Sakai en-aut-mei=Kazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AzumaKoichi en-aut-sei=Azuma en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KudoKeita en-aut-sei=Kudo en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NishioKazuto en-aut-sei=Nishio en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NakagawaKazuhiko en-aut-sei=Nakagawa en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HayashiHidetoshi en-aut-sei=Hayashi en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TeramuraTakeshi en-aut-sei=Teramura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=YonesakaKimio en-aut-sei=Yonesaka en-aut-mei=Kimio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= affil-num=1 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=2 en-affil=Division of Cell Biology for Regenerative Medicine, Institute of Advanced Clinical Medicine, Kindai University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Pathology, Kindai University Faculty of Medicine kn-affil= affil-num=4 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Cell Biology for Regenerative Medicine, Institute of Advanced Clinical Medicine, Kindai University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Thoracic Oncology, Osaka International Cancer Institute kn-affil= affil-num=7 en-affil=Department of Medical Oncology, Kishiwada City Hospital kn-affil= affil-num=8 en-affil=Department of Medical Oncology, Kishiwada City Hospital kn-affil= affil-num=9 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Genome Biology, Kindai University Faculty of Medicine kn-affil= affil-num=11 en-affil=Division of Respirology, Neurology, and Rheumatology, Department of Internal Medicine, Kurume University School of Medicine kn-affil= affil-num=12 en-affil=Department of Medical Oncology, National Hospital Organization Osaka Minami Medical Center kn-affil= affil-num=13 en-affil=Department of Genome Biology, Kindai University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=15 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=16 en-affil=Division of Cell Biology for Regenerative Medicine, Institute of Advanced Clinical Medicine, Kindai University Faculty of Medicine kn-affil= affil-num=17 en-affil=Department of Medical Oncology, Kindai University Faculty of Medicine kn-affil= END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue= article-no= start-page=100972 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Highly sensitive detection of cancer cells using a voltage-tuned terahertz chemical microscope en-subtitle= kn-subtitle= en-abstract= kn-abstract=Terahertz chemical microscopy (TCM) is a promising label-free technique for detecting biochemical interactions by monitoring changes in terahertz (THz) wave emission from semiconductor sensing plates. However, quantitative biological detection has been hindered by large plate-to-plate variations originating from uncontrolled depletion-layer electric fields formed during fabrication. These variations shift the response curve of THz amplitude and reduce reproducibility and sensitivity. Here, we introduce a voltage-tuned sensing plate that allows direct control of the depletion-layer electric field by applying a bias voltage to the Si layer of the sensing plate. This enables deliberate adjustment of surface potential and alignment of the THz response curve to the region of highest gain. Using lung adenocarcinoma cells (PC9) captured via AE1/AE3 antibodies targeting specific cell-surface antigens, we demonstrate that voltage tuning enhances detection sensitivity by up to 50-fold and restores linearity between THz amplitude and the logarithm of cell concentration, even in plates with negligible response at 0 V. These findings establish voltage control as a simple, universally applicable strategy to stabilize TCM performance, reduce fabrication-induced variability, and improve analytical sensitivity for biosensing and materials-analysis applications. en-copyright= kn-copyright= en-aut-name=DingXue en-aut-sei=Ding en-aut-mei=Xue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhmiYuto en-aut-sei=Ohmi en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Medical Support, Okayama University Hospital kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Terahertz chemical microscopy kn-keyword=Terahertz chemical microscopy en-keyword=Voltage tuning kn-keyword=Voltage tuning en-keyword=Cancer cells kn-keyword=Cancer cells en-keyword=Surface potential kn-keyword=Surface potential END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue= article-no= start-page=102295 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=Robot-assisted pulmonary lobectomy after subtotal esophagectomy in the prone position: A unified port strategy en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=BabaTomohiro en-aut-sei=Baba en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=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 General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=229 cd-vols= no-issue=2 article-no= start-page=jeb251318 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Insulin-like peptide has antagonistic pleiotropic effects on male combat traits and survival traits in an armed beetle en-subtitle= kn-subtitle= en-abstract= kn-abstract=The expression of sexually selected traits, such as exaggerated weapons and ornaments, often entails trade-offs against life-history traits. While phenotypic trade-offs are well documented, the underlying molecular physiological mechanisms remain largely unexplored. In this study, we investigated the potential role of an insulin-like peptide, ILP2, in mediating the trade-off between sexually selected combat traits and survival traits in the broad-horned flour beetle, Gnatocerus cornutus. RNA interference (RNAi)-mediated knockdown (KD) of ILP2 during larval stages resulted in a reduction in the development of mandibular horns and overall body size. Interestingly, ILP2 KD males had increased lipid storage and enhanced starvation tolerance, indicating a shift in resource allocation from sexually selected traits to survival traits. Behaviorally, ILP2 KD males showed decreased locomotor activity and reduced aggression, leading to lower combat success. These findings suggest that ILP2 functions as a key mediator in the allocation of resources between combat and survival traits, highlighting its pleiotropic effects on morphology, metabolism and behavior. Our study provides novel insights into the molecular physiological mechanisms underlying life-history trade-offs associated with sexually selected traits. en-copyright= kn-copyright= en-aut-name=KatoTakumi en-aut-sei=Kato en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimineChiho en-aut-sei=Yoshimine en-aut-mei=Chiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiokaHaruna en-aut-sei=Fujioka en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsukiMasako en-aut-sei=Katsuki en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkadaKensuke en-aut-sei=Okada en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkadaYasukazu en-aut-sei=Okada en-aut-mei=Yasukazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Science, Nagoya University kn-affil= affil-num=2 en-affil=Graduate School of Science, Tokyo Metropolitan University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Science, Nagoya University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Science, Nagoya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=3 article-no= start-page=e0339600 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early administration of renin–angiotensin system inhibitors improves survival and cardiac remodeling in heart failure with preserved ejection fraction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heart failure with preserved ejection fraction (HFpEF) is a major cardiovascular disease that accounts for 50% of all cases of heart failure. Patients with HFpEF have limited therapeutic options because of the complex pathogenesis of this disease. Decreased nitric oxide (NO) levels and increased renin–angiotensin system (RAS) activity may be associated with HFpEF pathogenesis. However, whether soluble guanylate cyclase (sGC) stimulators and RAS inhibitors protect against HFpEF remains unclear. This study aimed to evaluate the preventive effects of RAS inhibitors captopril (Cap) and/or sacubitril/valsartan (Sac/Val) and sGC stimulator vericiguat (Ver) on HFpEF progression. HFpEF was induced in 8-week-old male Wistar rats through intake of L-arginine methyl ester and a high-fat diet. Results showed that the survival rate after 8 weeks of treatment was 100% in the normal diet (Cont group), Cap, and Sac/Val groups, whereas it was approximately 20% in the HFpEF and Ver groups. No significant differences in the left ventricular systolic function were found. In addition, histochemistry revealed that myocardial hypertrophy and interstitial fibrosis obviously increased in the HFpEF group but not in the Cap and Sac/Val groups compared with the Cont group. Furthermore, RNA sequencing analysis showed that the expression of genes related to inflammatory response, hypertrophy, and extracellular matrix–receptor interaction increased in the HFpEF group and decreased in the Cap and Sac/Val groups. In conclusion, early administration of Cap or Sac/Val may reduce the risk of developing HFpEF by inhibiting the RAS pathway rather than the NO-sGC-cGMP pathway. en-copyright= kn-copyright= en-aut-name=KonoYuka en-aut-sei=Kono en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SonodaKunihiro en-aut-sei=Sonoda en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtakeKazuo en-aut-sei=Ohtake en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtaAkinobu en-aut-sei=Ota en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoShusei en-aut-sei=Yamamoto en-aut-mei=Shusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaHinako en-aut-sei=Nakayama en-aut-mei=Hinako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukuokaTaketo en-aut-sei=Fukuoka en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiYuki en-aut-sei=Kawai en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TagoHaruka en-aut-sei=Tago en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeNobuhisa en-aut-sei=Watanabe en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SatoIkumi en-aut-sei=Sato en-aut-mei=Ikumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=KitamoriKazuya en-aut-sei=Kitamori en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=WatanabeShogo en-aut-sei=Watanabe en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Collage of Human Life and Environment, Kinjo Gakuin University kn-affil= affil-num=3 en-affil=School of Pharmacy, Faculty of Pharmaceutical Science, Josai University kn-affil= affil-num=4 en-affil=Collage of Human Life and Environment, Kinjo Gakuin University kn-affil= affil-num=5 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=Academic Field of Health Science, Okayama University kn-affil= affil-num=12 en-affil=Academic Field of Health Science, Okayama University kn-affil= affil-num=13 en-affil=Collage of Human Life and Environment, Kinjo Gakuin University kn-affil= affil-num=14 en-affil=Academic Field of Health Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue= article-no= start-page=1759690 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a generative AI agent for family support in implementing family-based treatment for children and adolescents with anorexia nervosa en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Family-based treatment (FBT) is a first-line psychotherapy for children and adolescents with anorexia nervosa (AN). However, families must understand the principles of FBT, provide meal support, and manage their children's pathological behaviors. Difficulties occur outside clinic hours when it is impossible to consult professionals. This “support gap” increases caregivers’ psychological distress and threatens their treatment continuity. To the best of our knowledge, this is the first domain-specific generative artificial intelligence (AI) agent designed to provide situation-specific, FBT-concordant advice and psychological support.
Methods: The system integrates three components: (1) an FBT-specific knowledge base constructed from treatment manuals, family guides, guideline-compliant resources, and a clinical Q&A corpus; (2) a multistage natural language processing pipeline using Retrieval-Augmented Generation (RAG), with intent and sentiment analyses; and (3) safety guardrails that prohibit unsolicited numerical goals or direct hospitalization recommendations and standardized escalation to clinicians. When strong negative emotions are detected, empowerment messages are dynamically incorporated to maintain caregivers’ confidence. Six clinicians with expertise with pediatric mental health authored queries that simulated common FBT-related concerns and evaluated each response for clinical appropriateness and safety, and classified problems as information insufficiency, not FBT concordant, or escalation insufficiency.
Results: Of the 477 queries, 57.0% were FBT-related, 24.5% were general AN, 16.5% were parental psychological distress, and 1.8% were related to other topics. The clinically appropriate response rate was 91.6% (437/477), including 92.3% for FBT-related questions, 88.0% for general knowledge, 93.7% for psychological distress, and 100.0% for other questions. Clinically inappropriate responses (8.4%) were mainly attributable to information insufficiency; not FBT concordant (1.8% of FBT-related responses) and escalation insufficiency (0.6% of all dialogs) rarely occurred.
Discussion: In this expert review, the safety-gated RAG system predominantly generated FBT-concordant responses that provided meal-level guidance and empathic empowerment-oriented support to families. By proceduralizing complex FBT concepts and presenting multiple response options for pathological behaviors, the system translates FBT principles into practical guidance supporting refeeding adherence, preserving family self-efficacy, and suggesting that domain-specific AI may help bridge structural limitations in FBT. Usability studies and randomized controlled trials are warranted to determine their impact on caregiver burden, self-efficacy, treatment adherence, and clinical outcomes. en-copyright= kn-copyright= en-aut-name=HanzawaMana en-aut-sei=Hanzawa en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoriuchiMakiko en-aut-sei=Horiuchi en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatayamaHideki en-aut-sei=Katayama en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 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=14 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= affil-num=2 en-affil=Department of Medical Informatics and Clinical Support Technology Development, Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= affil-num=7 en-affil=Clinical Psychology Section, Department of Medical Support, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= affil-num=9 en-affil=Life Natural Science and Technology, Graduate School of Environmental, Okayama University kn-affil= affil-num=10 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Palliative and Supportive Care, Okayama University Hospital kn-affil= affil-num=12 en-affil=NEC Corporation kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Pediatrics, Okayama University Hospital Medical Center for Children kn-affil= en-keyword=anorexia nervosa kn-keyword=anorexia nervosa en-keyword=caregiver burden kn-keyword=caregiver burden en-keyword=family support kn-keyword=family support en-keyword=family-based treatment kn-keyword=family-based treatment en-keyword=generative AI agent kn-keyword=generative AI agent en-keyword=large language model kn-keyword=large language model en-keyword=retrieval-augmented generation kn-keyword=retrieval-augmented generation 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=Unraveling the structural features of Dion–Jacobson-type layered perovskite-related material HCa2Nb3O10·1.5H2O en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hydrated layered oxides are widely encountered, yet the presence of disordered interlayer water often complicates crystal structure determination from laboratory X-ray diffraction. Here, we report the crystal structure of the Dion–Jacobson-type layered perovskite-related material HCa2Nb3O10·1.5H2O, solved from synchrotron X-ray diffraction data by combining direct methods in reciprocal space, Le Bail whole-pattern fitting, and Rietveld refinement. The hydrate crystallizes in a tetragonal structure with space group P42212 (a = 7.7070(5) Å, c = 32.4870(3) Å). Incorporation of partially occupied interlayer water-oxygen sites on the (110) plane at z = 0 and 1/2 successfully reproduces the low-angle 00l reflections while preserving the Ca2Nb3O10 framework. The resulting crystallographic model explicitly resolves the arrangement of interlayer water molecules and provides a robust structural foundation for band-structure calculations as well as for the rational design of hydration-controlled intercalation, exfoliation, and composite materials based on layered perovskite-related materials. en-copyright= kn-copyright= en-aut-name=ZhangZihao en-aut-sei=Zhang en-aut-mei=Zihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanoJun en-aut-sei=Kano en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaShu en-aut-sei=Morita en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimokawaHiromu en-aut-sei=Shimokawa en-aut-mei=Hiromu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OsadaMinoru en-aut-sei=Osada en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Institute of Materials and Systems for Sustainability (IMaSS), Nagoya University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Materials Chemistry and Institute of Materials and Systems for Sustainability (IMaSS), Nagoya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=100082 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=Pharmaceutical agents targeting KATP channel modulate sweet taste sensitivity in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sweet detection involves at least two mechanisms: a G-protein coupled sweet taste receptor (Tas1r2/Tas1r3) and glucose transporters. As in pancreatic β-cells, glucose transport may lead to closure of ATP-sensitive potassium (KATP) channels. Since expression of KATP channels in sweet taste cells has been reported, modulation of KATP channel activity would affect sweet taste sensitivity. Here, we examined the effect of glibenclamide (a KATP channel closer) and diazoxide (an opener) on mouse taste behavior. Glibenclamide selectively reduced taste sensitivity to glucose without affecting responses to sucrose or sucralose compared to insulin, suggesting selective impairment of the transporter-dependent pathway. In contrast, diazoxide broadly suppressed responses to all tested sweeteners, indicating a generalized effect on sweet detection. Neither drug altered responses to non-sweet taste. These findings suggest that pharmacological modulation of KATP channel differently influences sweet taste; closers reduce glucose sensitivity whereas openers attenuate response to multiple sweeteners. en-copyright= kn-copyright= en-aut-name=SawaiChika en-aut-sei=Sawai en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangKuanyu en-aut-sei=Wang en-aut-mei=Kuanyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaHirotaka en-aut-sei=Ueda en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Sweet taste receptor kn-keyword=Sweet taste receptor en-keyword=Glucose transporter kn-keyword=Glucose transporter en-keyword=Diabetes kn-keyword=Diabetes en-keyword=Taste disorder kn-keyword=Taste disorder en-keyword=Cephalic phase insulin release kn-keyword=Cephalic phase insulin release END start-ver=1.4 cd-journal=joma no-vol=370 cd-vols= no-issue= article-no= start-page=199761 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=Toward in planta studies of persistent fungal viruses in a model plant en-subtitle= kn-subtitle= en-abstract= kn-abstract=A model plant, Nicotiana benthamiana, was examined as a host for persistent fungal viruses capable of crossing organismal kingdoms. Protoplasts of N. benthamiana were transfected with a mixture of virions of a betapartitivirus, Rosellinia necatrix partitivirus 18 (RnPV18), and an alphapartitivirus, RnPV19, and were then subjected to plantlet regeneration. Primary RT-PCR-based screening showed that nearly 100% of the resulting calli tested positive for RnPV18, whereas approximately 90% were positive for RnPV19. However, secondary screening performed at a later stage of tissue culture revealed that only 6% of the calli retained RnPV19, whereas approximately 33% retained RnPV18. These results suggest that the calli were chimeric, consisting of virus-infected and virus-free sectors, and that the partitiviruses were progressively lost during callus maintenance. It is also possible that these fungal partitiviruses were unable to fully adapt to, or counteract, host defense responses sufficiently to establish stable infection. We succeeded in obtaining RnPV18-positive calli and suspension cultures that maintained the virus at detectable levels, as shown by northern blotting, after prolonged subculture for at least 9 months. High-throughput small RNA analyses revealed both similarities and differences in virus-derived small RNA profiles among protoplasts, calli, and suspension cultures. Viral genome analyses further revealed developmental stage-specific and stage-independent substitutions compared with the RnPV18 genomic sequence maintained in the original fungal host. Interestingly, a C-to-U mutation in the RNA-dependent RNA polymerase-encoding region of RnPV18 was detected much more frequently in a particular line, designated B21, than in another stably RnPV18-infected line, P8, irrespective of whether the virus was maintained in suspension cultures or calli. This may explain why virus accumulation in B21 calli and suspension cultures was much lower than that in P8 cell cultures, as RNA-seq analyses showed 159 K counts per million for P8 versus 44 K counts per million for B21. Taken together, this study provides a platform for investigating partitiviruses and other ubiquitous persistent viruses, which are generally difficult to inoculate experimentally. en-copyright= kn-copyright= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FavarettoFrancesco en-aut-sei=Favaretto en-aut-mei=Francesco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IchikawaHiroaki en-aut-sei=Ichikawa en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaruyamaKazuyuki en-aut-sei=Maruyama en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Cross-kingdom infection kn-keyword=Cross-kingdom infection en-keyword=Tissue culture kn-keyword=Tissue culture en-keyword=Partitivirus kn-keyword=Partitivirus en-keyword=dsRNA virus kn-keyword=dsRNA virus en-keyword=Nicotiana, benthamiana kn-keyword=Nicotiana, benthamiana en-keyword=Callus kn-keyword=Callus en-keyword=Suspension culture kn-keyword=Suspension culture en-keyword=Model plant kn-keyword=Model plant END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=6 article-no= start-page=002255 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ICTV Virus Taxonomy Profile: Rhabdoviridae 2026 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The family Rhabdoviridae comprises viruses with unsegmented, bi-segmented or tri-segmented negative-sense (−) RNA genomes of 10–16 kb. Virions are typically enveloped, with bullet-shaped or bacilliform morphology, but can also be non-enveloped filaments. Rhabdoviruses infect plants or animals, including vertebrates or invertebrates such as arthropods, which can serve as single hosts or act as biological vectors for transmission to animals or plants. Rhabdoviruses include important pathogens of humans, livestock, fish or agricultural crops.

Electrical conductivity increases by more than seven orders of magnitude between 800 and 1700 K and exhibits two distinct conduction regimes separated by a transition at ~ 1500–1700 K. The high-temperature regime is characterized by large activation enthalpies (ΔH ≈ 1.8–2.3 eV), whereas the low-temperature regime shows much lower values (ΔH ≈ 0.19–0.31 eV). Stepwise annealing experiments reveal a pronounced thermal-history dependence: repeated heating to progressively higher maximum temperatures (Tmax) produces metastable conductivity states, enhancing low-temperature conductivity by up to six orders of magnitude and systematically reducing activation enthalpy. This behavior indicates activation and freezing-in of defect-related charge carriers. Negative activation volumes further support a hopping-type conduction mechanism. Although Ti³⁺ was not directly detected, the combination of reducing experimental conditions, Al³⁺ impurities (~ 0.35 wt% Al₂O₃), low activation energies, and strong thermal memory is most consistent with small-polaron hopping involving Ti³⁺–Ti⁴⁺ pairs. At lunar core–mantle boundary temperatures, geikielite reaches conductivities of 10¹–10² S/m, exceeding those of olivine and overlapping estimates for the lunar low-velocity zone. Our results demonstrate that solid-state Ti-rich oxides can produce high electrical conductivity without partial melting, providing new constraints on the thermochemical evolution and electromagnetic structure of the lunar interior. en-copyright= kn-copyright= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiDaisuke en-aut-sei=Yamazaki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Electrical conductivity kn-keyword=Electrical conductivity en-keyword=Geikielite kn-keyword=Geikielite en-keyword=High-pressure and high-temperature experiment kn-keyword=High-pressure and high-temperature experiment en-keyword=Ilmenite kn-keyword=Ilmenite en-keyword=Metastable defect states kn-keyword=Metastable defect states END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=100163 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=Heteroarylation of mono- and dichloroarenes via phenothiazine organophotoredox catalysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=2-Arylpyrroles are key structural motifs found in a wide range of pharmaceuticals and functional materials. Although the photocatalytic heteroarylation of pyrroles with aryl iodides and bromides has been extensively developed for the synthesis of 2-arylpyrroles, the corresponding reactions using aryl chlorides remain relatively unexplored owing to the high energy barrier associated with C(sp2)–Cl bond activation. Herein, we report a phenothiazine-based organophotoredox-catalyzed heteroarylation of aryl chlorides with pyrroles for the synthesis of diverse 2-arylpyrroles. Notably, dichloroarenes also efficiently undergo heteroarylation to afford the corresponding products. Therefore, the present reaction represents a versatile approach to heteroarylation and provides a valuable tool for the synthesis of pharmaceuticals and functional materials. en-copyright= kn-copyright= en-aut-name=OishiMasato en-aut-sei=Oishi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=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=Heteroarylation kn-keyword=Heteroarylation en-keyword=Photoredox catalysis kn-keyword=Photoredox catalysis en-keyword=Aryl chloride kn-keyword=Aryl chloride en-keyword=Phenothiazine kn-keyword=Phenothiazine en-keyword=Visible light kn-keyword=Visible light END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=pcag055 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Involvement of tRNA thiolation in uORF-mediated translational regulation during Xylogenesis in Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-transcriptional modification of tRNAs is an important mechanism for regulating translation efficiency and cellular homeostasis, yet its contribution to upstream open reading frame (uORF)-mediated translational control remains largely unexplored. In this study, we investigated the role of tRNA thiolation in thermospermine-dependent regulation of xylem development in Arabidopsis thaliana. Using a suppressor screen of the thermospermine-deficient mutant acaulis5 (acl5), which exhibits dwarfism and excessive xylem differentiation, we identified suppressor-of-acl502 (sac502) as a recessive loss-of-function allele of CTU2, a gene encoding a key enzyme in the biosynthesis of the wobble uridine modification 5-methoxycarbonylmethyl-2-thiouridine. Mutations in other components of the same modification pathway, including ROL5 and TRM9, similarly suppressed the acl5 phenotype. Translational analyses using 5′ leader-GUS reporter constructs revealed that the ctu2 mutation did not enhance translation of the mRNA containing a thermospermine-responsive uORF of SAC51, but instead significantly reduced translation of that of SACL3, a member of the SAC51 family, and that of LONESOME HIGHWAY (LHW), which contains another conserved uORF in the 5′ leader region. Polysome profiling further demonstrated decreased association of SACL3 and LHW mRNAs with actively translating ribosomes in ctu2. Genetic interaction analyses supported the conclusion that the suppression of excessive xylem formation in acl5 by ctu2 is attributable to reduced LHW activity. In addition, ctu2 mutants displayed increased sensitivity to exogenous thermospermine, resembling the response of lhw mutants. Together, our results reveal that tRNA thiolation contributes to uORF-mediated translational regulation of key developmental regulators and identify tRNA modification as an important regulatory layer controlling vascular development. en-copyright= kn-copyright= en-aut-name=NishiiYuichi en-aut-sei=Nishii en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ArakiDaichi en-aut-sei=Araki en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaraumiMitsuru en-aut-sei=Saraumi en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiTaku en-aut-sei=Takahashi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Arabidopsis kn-keyword=Arabidopsis en-keyword=mRNA translation kn-keyword=mRNA translation en-keyword=thermospermine kn-keyword=thermospermine en-keyword=tRNA thiolation kn-keyword=tRNA thiolation en-keyword=uOR kn-keyword=uOR END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=103382 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=AI-assisted writing feedback in EFL: Tracking student performance and reflections en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explores how AI-assisted writing feedback supports English as a Foreign Language (EFL) learners' writing development and feedback literacy in a Japanese university. Twenty-one first-year students completed nine Write & Improve (W&I) tasks, progressing from descriptive to argumentative essays. Each task was revised following W&I feedback, and students were asked to write a short reflective log. An explanatory mixed-methods approach was adopted, combining quantitative analyses of writing performance and linguistic features with qualitative coding of students' reflections. Findings showed measurable gains in both higher- and lower-level groups, with particularly notable improvement among lower-level students in complexity, fluency, and sophistication. While the higher group consistently outperformed the lower group in Term 1, this gap narrowed in Term 2. Reflection logs provided important insights into feedback literacy: students initially valued W&I for surface-level corrections but later expressed frustration as tasks became more complex and scores plateaued. This tendency was especially evident among lower-level students, reflecting both the affordances and limitations of automated feedback. The study concludes that AI-assisted tools can foster writing development and emerging feedback literacy, but sustained progress requires teacher mediation. Integrating Automated Writing Evaluation (AWE) into ecological feedback environments - combining AI, teacher, and student reflection - offers a promising approach for sustainable L2 writing instruction. en-copyright= kn-copyright= en-aut-name=OtoshiJunko en-aut-sei=Otoshi en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujishimaNaomi en-aut-sei=Fujishima en-aut-mei=Naomi 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=Kawasaki Medical School kn-affil= en-keyword=EFL writing kn-keyword=EFL writing en-keyword=AI-assisted tools kn-keyword=AI-assisted tools en-keyword=feedback literacy kn-keyword=feedback literacy en-keyword=ecological environments kn-keyword=ecological environments en-keyword=Write & Improve kn-keyword=Write & Improve 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=Phase behaviour of liquid CO2 with an impurity of water: influence of CO2 hydrate en-subtitle= kn-subtitle= en-abstract= kn-abstract=The solubility of water in liquid CO2 coexisting with CO2 hydrate or liquid water is evaluated in order to investigate the thermodynamic conditions to avoid the formation of CO2 hydrate in the transportation processes of liquid CO2. To this end, theoretical calculations have been carried out to obtain the chemical potentials of water and CO2 in all the phases involved in their coexistence. The solubility of water in liquid CO2 coexisting with liquid water decreases with decreasing temperature over a wide range of temperature and pressure, except for in the vicinity of the critical point of CO2. The decrease in the solubility is further enhanced by the formation of hydrate. We estimate the Gibbs energy of hydrate formation, which is an important property for sequestration of CO2, for cases where the temperature or pressure of water-saturated liquid CO2 decreases. We also estimate the amount of water precipitated as hydrate during these processes, which has a direct bearing on flow assurance in CO2 transportation. The present study will contribute to the development of a low-energy, safe CO2 transport network aiming at achieving large-scale carbon neutrality. en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiMunetaka en-aut-sei=Takeuchi en-aut-mei=Munetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriYoshihito en-aut-sei=Mori en-aut-mei=Yoshihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KonoTakumi en-aut-sei=Kono en-aut-mei=Takumi 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=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= affil-num=4 en-affil=Engineering Advancement Association of Japan kn-affil= affil-num=5 en-affil=Ochanomizu University kn-affil= affil-num=6 en-affil=Engineering Advancement Association of Japan kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=6 article-no= start-page=e110548 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathway Enrichment Analysis of Whole-Exome Sequencing Data from Formalin-Fixed, Paraffin-Embedded Enucleated Eyes with Retinoblastoma and Choroidal Malignant Melanoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Intraocular tumors are extremely rare, small in size, and difficult to approach by biopsy. In the era of cancer genome analysis, we designed a pilot study to perform whole-exome sequencing of formalin-fixed paraffin-embedded enucleated eyes of retinoblastoma and choroidal malignant melanoma as two major intraocular malignancies.
Methodology: Genomic DNA was isolated from intraocular tumor areas of 105 paraffin sections with a 5 μm thickness of seven enucleated eyes with retinoblastoma and seven eyes with choroidal malignant melanoma. One of 7 samples of retinoblastoma and another of seven samples of choroidal malignant melanoma were excluded from the study since the sequencing output and depth of reads were lower compared with the other samples. The sequencing data after quality control were aligned to the reference genome sequence (hg38, GRCh38 Assembly, Genome Reference Consortium Human Build 38), and the mapped reads were processed to improve data quality. Somatic mutations (single nucleotide variants, insertions and deletions, and multiple nucleotide variants) in each sample were extracted after excluding variants reported in a Panel of Normals (PON) from the 1000 Genomes Project. Additional selection criteria included a mutation depth of ≥5 reads and either no registration in or an allele frequency of less than 5% in the Tohoku Medical Megabank of Japan (ToMMo 60KJPN-SNV/INDEL Allele Frequency Panel).
Results: Candidate genes with somatic mutations were selected by three criteria: genes with the same mutation shared by two samples or more, recurrently mutated genes three times or over, and genes of driver candidates identified in combining several different driver mutation-detecting programs by Integrative OncoGenomics (IntOGen). Using candidate genes detected by any of the three criteria as input, enrichment analyses identified 28 pathways in Gene Ontology (GO) and 2 pathways in the Kyoto Encyclopedia of Genes and Genomes (KEGG) for retinoblastoma, while 385 pathways in GO, 12 in KEGG, 2 in the Hallmark gene set of the Molecular Signatures Database (MSigDB), and 47 in Reactome were identified for choroidal malignant melanoma. The enrichment maps showed three major pathways differently in retinoblastoma and choroidal malignant melanoma: one with dynein in retinoblastoma and another with MET in choroidal malignant melanoma.
Conclusions: Although there were limitations related to the small amounts of DNA available from formalin-fixed, paraffin-embedded small-sized tissues and the absence of matched normal control tissue, whole-exome sequencing provided clues to somatic mutations that were enriched in specific pathways and differed between retinoblastoma and choroidal malignant melanoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoAkira en-aut-sei=Saito en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AmemiyaMitsuhiro en-aut-sei=Amemiya en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamitsujiShigeo en-aut-sei=Kamitsuji en-aut-mei=Shigeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Medical Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Genomic Statistics, Stagen Co.

Macroceras en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hybridization can hinder or promote diversification, and growing genomic evidence suggests that it can facilitate adaptation and speciation. Despite recent progress, however, the quantitative contribution and temporal scope of hybridization to diversification remain poorly understood. The genus Epimedium is a recently diverged lineage, and sect. Macroceras largely consists of endemic species in Japan that are distributed across diverse environments, including limestone, serpentine, coastal habitats, heavy-snow regions, and regions with mild winters. Although natural hybridization and hybrid species have been reported in this section, molecular evidence demonstrating the contribution of hybridization to lineage diversification is limited. We reconstructed phylogenetic relationships using genome-wide single-nucleotide polymorphism (SNP) data from Epimedium sect. Macroceras and tested for genomic signatures consistent with hybridization. Phylogenetic analyses suggest that E. koreanum from Korea is sister to Japanese Epimedium lineages, consistent with an initial colonization of Japan from the Korean Peninsula. The analyses also revealed complex relationships among Japanese species and frequent signals of historical interspecific introgression. Our results are consistent with a history of recent diversification in sect. Macroceras accompanied by introgressive hybridization, which may have contributed to diversification across heterogeneous environments in Japan. This study provides the first genome-wide insights into the evolutionary history of Epimedium sect. Macroceras and reveals complex reticulate relationships among the lineages. en-copyright= kn-copyright= en-aut-name=KusatakeEmi en-aut-sei=Kusatake en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonishiMomoka en-aut-sei=Konishi en-aut-mei=Momoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomokuniShuto en-aut-sei=Tomokuni en-aut-mei=Shuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanagiYosuke en-aut-sei=Yanagi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KariyamaShungo en-aut-sei=Kariyama en-aut-mei=Shungo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItohTakehito en-aut-sei=Itoh en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyodaAtsushi en-aut-sei=Toyoda en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KimSeung-Chul en-aut-sei=Kim en-aut-mei=Seung-Chul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MimuraMakiko en-aut-sei=Mimura en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Biology, Okayama University kn-affil= affil-num=2 en-affil=Department of Biology, Okayama University kn-affil= affil-num=3 en-affil=Department of Biology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biology, Okayama University kn-affil= affil-num=5 en-affil=Society of Kurashiki Museum of Natural History kn-affil= affil-num=6 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Department of Genomics and Evolutionary Biology, National Institute of Genetics kn-affil= affil-num=8 en-affil=Department of Biological Sciences, Sungkyunkwan University kn-affil= affil-num=9 en-affil=Department of Biology, Okayama University kn-affil= en-keyword=Phylogenomics kn-keyword=Phylogenomics en-keyword=Introgression kn-keyword=Introgression en-keyword=Evolutionary radiation kn-keyword=Evolutionary radiation en-keyword=Pleistocene kn-keyword=Pleistocene en-keyword=Ecological divergence kn-keyword=Ecological divergence en-keyword=Reticulate evolution kn-keyword=Reticulate evolution END start-ver=1.4 cd-journal=joma no-vol=408 cd-vols= no-issue= article-no= start-page=117978 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=A flexible PVDF-based galloping flow sensor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective monitoring of low flow velocities in small rivers and irrigation channels is hindered by the power requirements and maintenance costs of existing technologies. This study proposes a novel flexible piezoelectric polymer flow sensor utilizing galloping vibration to detect flow velocity in the low range (≤ 0.1 m/s). The sensor features a flexible cantilever structure composed of a silicone rubber beam embedded with a polyvinylidene fluoride (PVDF) film and a tip pillar. Unlike conventional devices based on flow-induced vibration, the use of low-stiffness materials enables the induction of self-excited vibration even under weak fluid forces. Computational fluid dynamics (CFD) analysis has been conducted to optimize the tip shape; a D-shaped semicylinder is selected over a cylinder and a square prism because the geometry maximizes the lift force per unit mass, ensuring efficient energy conversion. To predict sensor behavior, a coupled mechanical-fluid-electrical model was developed. Specifically, the model accounts for the static deflection angle caused by fluid drag. Water channel experiments demonstrated that sensors with beam thicknesses under 4 mm successfully generated stable periodic outputs at 0.1 m/s, a regime previously difficult for galloping-based devices. Conversely, thicker beam which has a thickness of 8 mm achieved higher outputs at higher velocities but failed to actuate at low speeds. Furthermore, the study showed a vibration suppression phenomenon in flexible beams at high flow velocities due to excessive static deflection, which was accurately reproduced by the analytical model. These findings establish structural stiffness as the critical design parameter for optimizing the operable velocity range of flow sensors. en-copyright= kn-copyright= en-aut-name=KuroseMitsuki en-aut-sei=Kurose en-aut-mei=Mitsuki 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=SatoYuya en-aut-sei=Sato en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=HiejimaShinji en-aut-sei=Hiejima en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UedaTakeji en-aut-sei=Ueda en-aut-mei=Takeji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Hydro-VENUS Co., Ltd., Okayama University kn-affil= en-keyword=Flow velocity sensor kn-keyword=Flow velocity sensor en-keyword=Piezoelectric polymer kn-keyword=Piezoelectric polymer en-keyword=Flow induced vibration kn-keyword=Flow induced vibration en-keyword=Galloping vibration kn-keyword=Galloping vibration END start-ver=1.4 cd-journal=joma no-vol=408 cd-vols= no-issue= article-no= start-page=117938 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=Tip position estimation of a 3-DOF soft mechanism using artificial muscles with optical fibers en-subtitle= kn-subtitle= en-abstract= kn-abstract=McKibben-type pneumatic artificial muscles (PAMs) are lightweight and flexible soft actuators with a high power-to-weight ratio, and have been widely applied to rehabilitation devices, power-assist systems, and soft robotic mechanisms. By integrating sensing functions into PAMs, their usability and controllability can be enhanced, enabling the development of more practical and advanced soft mechanisms. We previously proposed a smart artificial muscle (SAM) by integrating an optical fiber into the braided sleeve of a McKibben-type PAM, which enables displacement estimation by measuring optical bending loss. The SAM is compatible with conventional PAM fabrication processes; however, the sensor output exhibits strong nonlinearity and time dependency. In this study, an LSTM-based state estimation framework is extended from a single SAM to a three-degree-of-freedom soft mechanism composed of multiple SAMs, where strong nonlinear coupling and mutual interference arise among actuators. In the proposed framework, the LSTM model jointly processes time-series data of multi-channel optical sensor outputs and applied pressures of the three SAMs, along with past estimated states as inputs. This structure enables the model to capture nonlinear coupling, hysteresis, and time-dependent behavior, allowing estimation of the tip position of the soft mechanism. Experimental results demonstrate that the proposed method accurately captures complex nonlinear dynamics and mutual mechanical interference among multiple SAMs, achieving accurate tip position estimation. These results indicate that SAMs with integrated sensing and actuation capabilities, combined with machine-learning-based estimation, provide an effective approach for state estimation of multi-DOF soft robotic mechanisms. en-copyright= kn-copyright= en-aut-name=OkadaRikimaru en-aut-sei=Okada en-aut-mei=Rikimaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TodaYuichiro en-aut-sei=Toda en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiuraShun en-aut-sei=Miura en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=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=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= affil-num=6 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Pneumatic artificial muscle kn-keyword=Pneumatic artificial muscle en-keyword=Smart artificial muscle kn-keyword=Smart artificial muscle en-keyword=Soft mechanism kn-keyword=Soft mechanism en-keyword=State estimation kn-keyword=State estimation en-keyword=Long short-term memory kn-keyword=Long short-term memory END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=26007 end-page= 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=Understory Vegetation Structure in Remnant Natural Forests and Acacia Plantations on Coastal Sand Dunes in North Central Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the coastal sand dune forests of North Central Vietnam, vegetation has been seriously damaged by war and overexploitation. To recover ecosystem functions, including sand stabilisation under harsh environments, exotic species like Acacia spp. have been planted as a monoculture. However, the long-term sustainability of this practice remains unclear. To assess the long-term effectiveness of revegetation with Acacia spp., this study aims to understand the differences and similarities in ecological characteristics of remnant natural forests and Acacia plantations on the coastal sand dune of North Central Vietnam by comparing understory vegetation structure and environmental conditions. We investigated the understory vegetation (height < 130 cm) in a total of 54 quadrants (1 m × 1 m), including nine natural forests and nine Acacia plantations. We compared diversity indices by mixed ANOVA and examined the differences in the understory vegetation structure between the two forest types through PERMANOVA. We also determined some abiotic environmental factors (e.g. light and soil water availability, and soil pH). We identified 951 individuals, with 792 found in natural forests and 159 in plantations. The species found in natural forests were well-distributed among Liana phanerophytes (Lp), Microphanerophytes (Mi), Mega-Mesophanerophytes (MM), and Cryptophytes (Cr). In contrast, species found in plantations were predominantly Cr, Hemicryptophytes (Hm), and MM. All diversity indices were significantly higher in natural forests (P < 0.05), and the NMDS analysis confirmed significant differences in the understory vegetation structure between natural forests and plantations. Only soil pH was significantly lower in natural forests (P < 0.05), while none of the environmental factors had a statistically significant impact on the variations in understory vegetation structure. Our results indicate that succession by native tree species does not seem to occur naturally in Acacia plantations. Hence, to restore and sustainably develop coastal sand dune forests in North Central Vietnam, it is essential to establish a scientifically based strategy for managing and protecting the remaining natural remnant forest areas. en-copyright= kn-copyright= en-aut-name=DoanTuan Quoc en-aut-sei=Doan en-aut-mei=Tuan Quoc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoTetsuya K. en-aut-sei=Matsumoto en-aut-mei=Tetsuya K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DinhTai Tien en-aut-sei=Dinh en-aut-mei=Tai Tien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeHung Thai en-aut-sei=Le en-aut-mei=Hung Thai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoTuan Ngoc Anh en-aut-sei=Ho en-aut-mei=Tuan Ngoc Anh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=HoHoang Thai Dac en-aut-sei=Ho en-aut-mei=Hoang Thai Dac kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirobeMuneto en-aut-sei=Hirobe en-aut-mei=Muneto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Ibaraki University, Graduate School of Science and Engineering kn-affil= affil-num=3 en-affil=Hue Union of Science and Technology Associations (HUSTA) kn-affil= affil-num=4 en-affil=Hue University, University of Agriculture and Forestry kn-affil= affil-num=5 en-affil=Hue Union of Science and Technology Associations (HUSTA) kn-affil= affil-num=6 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=7 en-affil=Hue Union of Science and Technology Associations (HUSTA) kn-affil= affil-num=8 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= en-keyword=natural forest kn-keyword=natural forest en-keyword=Acacia plantation kn-keyword=Acacia plantation en-keyword=coastal sand dunes forest kn-keyword=coastal sand dunes forest en-keyword=diversity kn-keyword=diversity en-keyword=understory vegetation kn-keyword=understory vegetation en-keyword=life forms kn-keyword=life forms en-keyword=environmental factor kn-keyword=environmental factor 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=20260606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Uniqueness of Dirichlet forms for random point fields in the absence of tail triviality en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider an infinite system of interacting Brownian motions that preserves a given random point field invariant. Such dynamics are constructed using Dirichlet form theory, which naturally leads to two Dirichlet forms for the random point field: the upper and the lower Dirichlet forms. A fundamental question is the uniqueness of the Dirichlet form: that is, whether these two forms coincide. This uniqueness has often been imposed as a key assumption in the Dirichlet form approach to the stochastic analysis for infinite particle systems. A sufficient condition for the uniqueness of the Dirichlet forms is known when the random point field is tail trivial. However, tail triviality has been established for only a limited class of random point fields. In this paper, we prove the uniqueness of the Dirichlet form without assuming tail triviality. The main contribution of this work is to establish the tail preserving property, which asserts that global properties of the system, such as particle density, are preserved under time evolution. As a consequence, our results also imply the strong uniqueness of solutions to the associated infinite-dimensional stochastic differential equations. en-copyright= kn-copyright= en-aut-name=KawamotoYosuke en-aut-sei=Kawamoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama university kn-affil= en-keyword=Infinite particle systems kn-keyword=Infinite particle systems en-keyword=Interacting Brownian motions kn-keyword=Interacting Brownian motions en-keyword=Uniqueness of Dirichlet forms kn-keyword=Uniqueness of Dirichlet forms en-keyword=Random matrices kn-keyword=Random matrices END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=94 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three-dimensional virtual planning reduces operative time in orthognathic surgery: a procedure-specific retrospective study incorporating additive manufacturing en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Three-dimensional virtual surgical planning (3D-VSP) is increasingly used in orthognathic surgery; however, procedure-specific evidence regarding its real-world impact on operative efficiency and intraoperative blood loss remains limited. This study evaluated the association between 3D-VSP implementation and operative time, and intraoperative blood loss across different orthognathic procedures.
Methods This retrospective cohort study included consecutive patients who underwent orthognathic surgery at a single academic institution before (2019–2020) and after (2023–2024) the full implementation of 3D-VSP integrated with in-house additive manufacturing (n = 344). Procedure-specific multivariable linear regression analyses were performed, adjusting for age, sex, and surgeon experience.
Results After 3D-VSP implementation, operative time was reduced by approximately 36 min in sagittal split ramus osteotomy (SSRO), 50 min in Le Fort I (LF1) combined with SSRO, and 42 min in segmental LF1 combined with SSRO, representing a 15–20% reduction in total operative time. No meaningful reduction was observed in intraoral vertical ramus osteotomy (IVRO)-based procedures. A statistically significant, but modest, reduction in intraoperative blood loss was observed only in SSRO. The time-saving effect was independent of surgeon experience.
Conclusion The clinical benefit of 3D-VSP in orthognathic surgery is procedure-dependent and most evident in geometrically complex SSRO-based operations. These findings support the targeted implementation of digital planning and additive manufacturing workflows to improve operative efficiency in routine practice. en-copyright= kn-copyright= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NishiyamaAkiyoshi en-aut-sei=Nishiyama en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 ORCID= en-aut-name=ObataKyoichi en-aut-sei=Obata en-aut-mei=Kyoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OnoKisho en-aut-sei=Ono en-aut-mei=Kisho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=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 and Maxillofacial Surgery, 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=Orthognathic surgery kn-keyword=Orthognathic surgery en-keyword=Surgical planning kn-keyword=Surgical planning en-keyword=Three-dimensional virtual surgical planning kn-keyword=Three-dimensional virtual surgical planning en-keyword=Operative time kn-keyword=Operative time en-keyword=Intraoperative blood loss kn-keyword=Intraoperative blood loss en-keyword=Additive manufacturing kn-keyword=Additive manufacturing en-keyword=Sagittal split ramus osteotomy kn-keyword=Sagittal split ramus osteotomy END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5 article-no= start-page=255 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260420 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=HLA-matched versus haploidentical donor transplantation with post-transplant cyclophosphamide: a study on behalf of the donor/source working group of the Japanese society for transplantation and cellular therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-transplant cyclophosphamide (PTCy) is now being increasingly applied to HLA-matched donor (MD) transplantation. Prior studies in Western countries have demonstrated that allogeneic hematopoietic cell transplantation (allo-HCT) employing PTCy yields better outcomes with HLA-matched donors (MDs) than with haploidentical donors (HIDs). However, the effect of HLA mismatch may differ among racial groups. We retrospectively analyzed adult patients with hematological malignancies who underwent their first allo-HCT with PTCy from MDs or HIDs registered to the Japanese registry database between 2013 and 2021. Among 63 (related, n = 33; unrelated, n = 30) and 1261 patients who received MD and HID allo-HCT with PTCy, 50 (related, n = 30; unrelated, n = 20) and 100 patients were assigned to MD and HID groups by 1:2 propensity score matching (PSM). The results showed that MD recipients had better neutrophil recovery (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.04–2.10; P = 0.031) and lower risk of non-relapse mortality (NRM) (HR, 0.19; 95% CI, 0.05–0.81; P = 0.024) than HID recipients. Multivariable analyses in the entire cohort before PSM confirmed these findings. Fatal infection was the primary cause of NRM in the HID group. This study is the first to demonstrate that, within a homogeneous Asian cohort, MD may have an advantage over HID in PTCy-based allo-HCT in facilitating neutrophil engraftment and reducing the risk of NRM. en-copyright= kn-copyright= en-aut-name=NakayaYosuke en-aut-sei=Nakaya en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamaeHirohisa en-aut-sei=Nakamae

We retrospectively analyzed the Japanese national transplantation registry to compare outcomes after first allogeneic hematopoietic stem cell transplantation in patients with HLA homozygous haplotypes. Donors were classified as homo-to-homo, defined as HLA-matched, or hetero-to-homo, defined as allele-level mismatches at HLA-A, -B, -C, and/or -DRB1 restricted to the host-versus-graft direction. The unrelated donor homo-to-homo group served as the reference. We included 691 patients: related donor homo-to-homo (n = 121), related donor hetero-to-homo (n = 76), unrelated donor homo-to-homo (n = 374), unrelated donor hetero-to-homo (n = 22), cord blood homo-to-homo (n = 40), and cord blood hetero-to-homo (n = 58). Compared with the unrelated donor homo-to-homo group, overall survival was inferior in the cord blood homo-to-homo group (adjusted hazard ratio [HR], 1.71; 95% confidence interval [CI], 1.11–2.64; P = 0.015), whereas the unrelated donor hetero-to-homo group showed a nonsignificant trend toward inferior overall survival (adjusted HR, 1.77; 95% CI, 0.97–3.22; P = 0.061). In this Japanese cohort, cord blood homo-to-homo transplantation was associated with inferior overall survival, whereas related donor hetero-to-homo and cord blood hetero-to-homo transplantation were not. These findings should be interpreted cautiously given the retrospective design and long study period, and require validation in contemporary, ethnically diverse cohorts. en-copyright= kn-copyright=

kn-abstract=Molecules featuring both sulfur and nitrogen atoms are privileged scaffolds in medicinal chemistry and biological systems. However, methods for the direct and regioselective installation of these heteroatoms onto alkenes remain limited. Herein, we report a visible-light-induced, three-component sulfanyloximation of styrenes utilizing thiols and N-nitrosamine as a bench-stable nitrogen oxide (NO) surrogate. This regioselective protocol operates under mild conditions with remarkable functional group tolerance. The synthetic utility of this methodology is further demonstrated by its extension to the synthesis of 2,3-disubstituted indoles and the divergent downstream derivatization of α-sulfanyl ketoxime products via imidoyl fluoride intermediates. An extensive mechanistic investigation supports a pathway initiated by thiyl radical addition to alkenes followed by radical coupling with in situ generated NO. en-copyright= kn-copyright= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TamuraToshiki en-aut-sei=Tamura en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkimotoShuta en-aut-sei=Akimoto en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Okayama 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= 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=A Case of Peripheral Odontogenic Myxofibroma Arising in the Palatal Gingiva of the Maxillary Second Premolar Region: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Odontogenic myxofibroma (OMF) is a rare benign mesenchymal odontogenic tumor characterized by myxoid stroma with a prominent fibrous component. Although it usually arises intraosseously within the jaws, the peripheral variant, peripheral odontogenic myxofibroma (POMF), which occurs in extraosseous soft tissues, is uncommon and may be clinically misdiagnosed as a reactive gingival lesion. We report a case of POMF in a 68-year-old man who was referred for evaluation of a painless, slowly enlarging swelling of the palatal gingiva in the left maxillary second premolar region, which had initially been diagnosed as chronic periodontitis at a local clinic. An intraoral examination revealed an elastic, firm mass with partial erythema on the palatal marginal gingiva. Panoramic radiography showed mild generalized horizontal bone loss without lesion-specific changes, and computed tomography revealed no bone resorption associated with the lesion. Exfoliative cytology was negative for intraepithelial lesions or malignancy. The lesion was excised with a 5-mm clinical margin, including periosteum, and superficial peripheral ostectomy of the adjacent cortical bone was performed. Histopathological examination revealed a myxoid stroma rich in mucinous matrix and collagen fibers, containing sparsely distributed spindle-shaped cells and scattered nests of odontogenic epithelium. Alcian blue staining revealed diffuse positivity, supporting the diagnosis of POMF. No recurrence was observed during a 2-year follow-up period. This case highlights a diagnostic pitfall in the tooth-bearing gingiva and underscores the importance of histopathological confirmation of persistent gingival masses. When imaging shows no apparent bone involvement, and clinical suspicion of malignancy is low, complete excision with an adequate soft-tissue margin and selective, limited bone removal may achieve local control while preserving the adjacent teeth; long-term follow-up remains advisable. en-copyright= kn-copyright= en-aut-name=MasuiMasanori en-aut-sei=Masui en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YutoriHirokazu en-aut-sei=Yutori en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimuraAi en-aut-sei=Fujimura en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery , Faculty of Medicine , Dentistry and Pharmaceutical Sciences Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery , Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery , Kagawa Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery , Faculty of Medicine , Dentistry and Pharmaceutical Sciences Okayama University kn-affil= en-keyword=case report kn-keyword=case report en-keyword=excisional biopsy kn-keyword=excisional biopsy en-keyword=palatal gingiva kn-keyword=palatal gingiva en-keyword=peripheral odontogenic myxofibroma kn-keyword=peripheral odontogenic myxofibroma en-keyword=peripheral odontogenic myxoma kn-keyword=peripheral odontogenic myxoma END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=6 article-no= start-page=e0350803 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A multicenter, randomized, parallel-group confirmatory study protocol to evaluate the efficacy of Soft Protector CPC, a novel oral mucosal protectant, in preventing oral mucositis and alleviating pain in patients with breast cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral mucositis is a frequent and debilitating adverse event observed in patients undergoing chemotherapy or radiotherapy. Current management strategies are limited in duration, require frequent application, and fail to address the mechanical irritation from teeth. A novel device, Soft Protector CPC, was developed to overcome these limitations. This multicenter, randomized, two-arm, open-label, confirmatory trial aims to evaluate the efficacy and safety of Soft Protector CPC in patients with breast cancer undergoing chemotherapy. A total of 154 participants will be randomly assigned in a 1:1 ratio to receive either oral care with Soft Protector CPC or oral care alone. The primary endpoint will be oral mucositis as assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) v3.0 during the comparative treatment period. The secondary endpoints will include CTCAE v3.0 during the continuous treatment period, oral mucositis, pain (CTCAE v5.0), quality of life (Patient Reported Outcomes-CTCAE version 1.0 [PRO-CTCAE v1.0], the 15-item oral health questionnaire of the European Organization For Research And Treatment Of Cancer [EORTC QLQ-OH15], and the pain Numeric Rating Scale), onset and site of mucositis, completion of chemotherapy, use of rescue medications, technical feasibility, and patient preference. The safety endpoints will include adverse events, device malfunction, and laboratory tests. This trial is expected to establish the clinical utility of the Soft Protector CPC for the prevention and management of oral mucositis, with the potential to improve the patients’ quality of life and adherence to cancer therapy.

While Schoenfeld’s three-axis heuristic framework is well known for this purpose, it primarily points toward increasing generality. Drawing on prior studies on the generalizability of empirical findings in educational research, this paper argues that an alternative research path is possible. Building on the distinction between prevalence and scope, it proposes two types of generality: the generality of a phenomenon within a specified scope and the generality of a theory. Correspondingly, it identifies two directions for research development: delimitation of the scope and generalization of a theory. Finally, the paper argues that research development based on this framework can be understood as progressive in the Lakatosian sense. While Schoenfeld’s framework suggests directions for individual studies, this framework guides competing research programmes by enabling both to progress through scope delimitation. en-copyright= kn-copyright= en-aut-name=UegataniYusuke en-aut-sei=Uegatani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshibashiIppo en-aut-sei=Ishibashi en-aut-mei=Ippo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Hiroshima University High School kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= en-keyword=Schoenfeld’s heuristic framework for situating research studies kn-keyword=Schoenfeld’s heuristic framework for situating research studies en-keyword=prevalence kn-keyword=prevalence en-keyword=generality kn-keyword=generality en-keyword=scope kn-keyword=scope en-keyword=delimitation of scope kn-keyword=delimitation of scope END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=3003 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photooxidative Copper(II) Catalysis for Promoting anti-Markovnikov Hydration of Alkenes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoredox catalysis enables the generation of radical intermediates under mild conditions, yet photoredox catalysts have heavily relied on precious transition metal complexes. Therefore, the development of photocatalysts based on earth-abundant metals is increasingly demanded. Here, we report a highly photooxidative capability of a heteroleptic copper(II) complex for promoting anti-Markovnikov hydration of alkenes. The copper(II) complex containing bathophenanthroline and 3,4-dimethoxybenzenethiolate ligands is generated in situ from copper(II) chloride dihydrate. Upon visible-light irradiation, the copper(II) complex is photoexcited and exhibits an excited-state lifetime sufficiently long to oxidize various alkenes, including aliphatic substrates. Consequently, anti-Markovnikov hydration can be achieved under mild conditions, and the late-stage functionalization of natural products and pharmaceutical derivatives is also feasible. The developed catalytic system can be extended for photooxidative reactions of alkenes, such as intramolecular cyclization reactions and anti-Markovnikov addition of nucleophiles other than water. en-copyright= kn-copyright= en-aut-name=OkuNaoki en-aut-sei=Oku en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukeKeito en-aut-sei=Fuke en-aut-mei=Keito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuiRikako en-aut-sei=Masui en-aut-mei=Rikako 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=MatsuiYasunori en-aut-sei=Matsui en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkedaHiroshi en-aut-sei=Ikeda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Okayama 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 Metropolitan University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka Metropolitan University kn-affil= affil-num=7 en-affil=Division of Applied Chemistry, 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=20260521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Juniperus sabina coverage on plant community structure in semiarid areas of China en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plant interactions are one of the fundamental processes shaping the structure and function of plant communities and help create species diversity. Species diversity affects the current functioning of ecosystems and their resistance and resilience to future climate change. In harsh environments such as drylands, positive plant–plant interactions are important in promoting species diversity. Juniperus sabina is an evergreen shrub that is native to the semiarid areas of northern China. Because J. sabina can modify some harsh environmental conditions in its role as a nurse plant, it is expected to facilitate species diversity, although it may exhibit allelopathic inhibition. Previous research has only examined effects of J. sabina coverage onα-diversity in a single-year, and its effects on the β-diversity of the plant community structure in the local ecosystem are still unclear. We compared environmental conditions and plant species composition inside and outside of 11 J. sabina patches to evaluate the effects of its coverage on the species diversity of the understory community structure through modifying microhabitat conditions. Water and nutrient conditions were higher inside the patches, whereas light conditions were higher outside. More perennial herbs and C3 plants were found inside and more annual herbs and C4 plants were found outside. There were different trends in α-diversity each year, while β-diversity was consistently greater inside the patches. This research suggests that the coverage of J. sabina can drive different community structures by providing heterogeneous environmental conditions, and would increase plant species diversity in the local ecosystem. en-copyright= kn-copyright= en-aut-name=QinLong en-aut-sei=Qin en-aut-mei=Long kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamabayashiAyaka en-aut-sei=Yamabayashi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoTetsuya K. en-aut-sei=Matsumoto en-aut-mei=Tetsuya K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangGuosheng en-aut-sei=Zhang en-aut-mei=Guosheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamanakaNorikazu en-aut-sei=Yamanaka en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirobeMuneto en-aut-sei=Hirobe en-aut-mei=Muneto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=College of Ecology and Environment, Inner Mongolia Agricultural University kn-affil= affil-num=5 en-affil=Arid Land Research Center, Tottori University kn-affil= affil-num=6 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= en-keyword=Nurse plant kn-keyword=Nurse plant en-keyword=Plant species diversity kn-keyword=Plant species diversity en-keyword=Plant species coexistence kn-keyword=Plant species coexistence en-keyword=Plant–plant interactions kn-keyword=Plant–plant interactions en-keyword=Mu Us sandy land kn-keyword=Mu Us sandy land END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=530 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photosynthetic Response of Larix gmelinii var. japonica Saplings After Exogenous Glutathione Foliar Application en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sapling survival and growth depend on photosynthetic assimilates. Therefore, improving physiological performance during early stages may enhance subsequent performance and nursery production. This study evaluated whether exogenous oxidized glutathione (GSSG), reported to enhance photosynthesis, improves the photosynthetic, physiological, and growth-related traits of Larix gmelinii var. japonica saplings. Sixteen saplings were assigned to four treatments: GSSG, 5-aminolevulinic acid, Hyponex, and a water control. Photosynthetic, nitrogen-related, and growth traits were measured before treatment and at 3, 6, 13, and 31 days after treatment, and biomass was assessed after three months. The GSSG treatment showed no difference in the net CO2 assimilation rate (Amax) compared with the control, but exhibited a significantly earlier peak at 6 days than the other treatments. This response was supported by the stability of GSSG-treated saplings against photoinhibition (Fv/Fm) and a tendency toward greater resilience to midday light stress (ΦPSII). Enhanced photosynthetic performance was associated with reduced carbon and nitrogen fluctuations and was accompanied by numerically greater root and stem biomass in the 2024 terminal shoots. Although fertilization effects were generally weak and transient, GSSG elicited notable responses, suggesting that the immediate enhancement of photosynthesis underlies its impact. However, its antioxidant properties under stressful conditions warrant further investigation. en-copyright= kn-copyright= en-aut-name=RahayuResa Sri en-aut-sei=Rahayu en-aut-mei=Resa Sri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshizukaWataru en-aut-sei=Ishizuka en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaritaAyu en-aut-sei=Narita en-aut-mei=Ayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyataRie en-aut-sei=Miyata en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KonHirokazu en-aut-sei=Kon en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyazakiYuko en-aut-sei=Miyazaki en-aut-mei=Yuko 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= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=3 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=4 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=5 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=7 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=exogenous glutathione kn-keyword=exogenous glutathione en-keyword=foliar fertilizer kn-keyword=foliar fertilizer en-keyword=Larix gmelinii var. japonica kn-keyword=Larix gmelinii var. japonica en-keyword=photosystem II quantum yield kn-keyword=photosystem II quantum yield en-keyword=photosynthetic rate kn-keyword=photosynthetic rate END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=181 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hypernatremia during the first week of life in very preterm infants and neurodevelopmental outcomes at 3 to 4 years of age: a cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Hypernatremia is a common electrolyte disorder in both term and preterm infants. Previous studies have suggested a correlation between hypernatremia and short-term complications in preterm infants, such as intraventricular hemorrhage and chronic lung disease. However, the relationship between hypernatremia and neurodevelopmental outcomes is less well understood. This study aimed to assess the association between hypernatremia during the first week of life and neurodevelopmental outcomes at 3–4 years of age in very preterm infants.
Methods This single-center, retrospective cohort study analyzed data from preterm infants born at less than 32 weeks of gestation between 2010 and 2020. Infants with peak whole blood sodium levels > 145 mEq/L during the first week of life were included in the hypernatremia group and those with ≤ 145 mEq/L in the non-hypernatremia group. The primary outcome was neurodevelopmental impairment (NDI) at 3–4 years of age, defined as developmental impairment (developmental quotient < 70), cerebral palsy, hearing impairment, or visual impairment. Secondary outcomes were the components of the primary outcome. We conducted Poisson regression analyses with robust variance, adjusting for perinatal confounders.
Results Of 272 infants with neurodevelopmental data, 82 and 190 infants were in the hypernatremia and non-hypernatremia groups, respectively. The median (interquartile range) gestational age and birth weight were 26.4 (25.1–28.0) and 28.7 (26.6–30.3) weeks and 860 (670–1062) and 997 (778–1264) g for infants in the hypernatremia and non-hypernatremia groups, respectively. Infants in the hypernatremia group had a greater incidence of NDI (29.3% vs. 14.7%, adjusted risk ratio [RR] 1.75, 95% CI 1.08–2.84) and cerebral palsy (8.5% vs. 1.6%, adjusted RR 5.5, 95% CI 1.72–17.63) than those in the non-hypernatremia group.
Conclusions Hypernatremia during the first week of life was associated with an increased risk of NDI at 3–4 years of age in very preterm infants. en-copyright= kn-copyright= en-aut-name=MurakamiMichiko en-aut-sei=Murakami en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei 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=TakeuchiAkihito en-aut-sei=Takeuchi en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraMakoto en-aut-sei=Nakamura en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KageyamaMisao en-aut-sei=Kageyama en-aut-mei=Misao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Neonatology, NHO Okayama Medical Center 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=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=5 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= en-keyword=Hypernatremia kn-keyword=Hypernatremia en-keyword=Development kn-keyword=Development en-keyword=Very preterm kn-keyword=Very preterm en-keyword=Cerebral palsy kn-keyword=Cerebral palsy END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=6 article-no= start-page=e70582 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors for Waiting List Mortality in Lung Transplant Candidates With Post‐Hematopoietic Stem Cell Transplantation Non‐Infectious Pulmonary Complications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Late-onset non-infectious pulmonary complications (LONIPCs) following hematopoietic stem cell transplantation (HSCT) are a known indication for need of lung transplantation. This study aimed to clarify the clinical characteristics of patients with LONIPCs after HSCT who were registered for lung transplantation and reveal the risk factors for waiting list mortality.
Methods: We retrospectively reviewed the clinical data of patients with LONIPCs after allogeneic HSCT who were referred to Okayama University Hospital and registered in the Japan Organ Transplant Network for deceased-donor lung transplantation between 2005 and 2023. Pediatric patients aged <18 years at the time of registration were excluded.
Results: Thirty-four patients were included in this study. Notably, two distinct phenotypic groups were identified: One with a bronchiolitis obliterans pattern on high-resolution computed tomography and a mixed ventilatory defect, and the other with a pleuroparenchymal fibroelastosis pattern and a restrictive ventilatory defect. The median waiting duration for a deceased-donor lung transplant was 662 days, and 16 patients died during the waiting period. The cumulative incidence of waiting list mortality was 20.6% (95% confidence interval [CI], 8.9%–35.6%) at 1 year and 46.1% (95% CI, 27.8%–62.7%) at 3 years. A history of pneumothorax, greater dyspnea on exertion, and higher serum Krebs von den Lungen-6 levels were associated with an increased risk of waiting list mortality.
Conclusion: In patients with LONIPCs after HSCT, a history of pneumothorax may be a marker of a poor prognosis and could serve as a criterion for referral of lung transplantation. en-copyright= kn-copyright= en-aut-name=HigoHisao en-aut-sei=Higo en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SenooSatoru en-aut-sei=Senoo en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakimotoSatoko en-aut-sei=Makimoto en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaganoTomohiro en-aut-sei=Nagano en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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=Department of Radiology, 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=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=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= en-keyword=hematopoietic stem cell transplantation kn-keyword=hematopoietic stem cell transplantation en-keyword=late-onset non-infectious pulmonary complications kn-keyword=late-onset non-infectious pulmonary complications en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=pneumothorax kn-keyword=pneumothorax END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=017803 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pressure calibrations of high-pressure large-volume presses at HPSTAR en-subtitle= kn-subtitle= en-abstract= kn-abstract=Large-volume presses (LVPs) are widely utilized in diverse research fields—including high-pressure physics, chemistry, materials science, and Earth and planetary sciences—to investigate the physical and chemical properties of materials under extreme high-pressure and high-temperature conditions. A prerequisite for achieving reproducible property measurements is the determination and control of pressure within experimental setups. However, the lack of precise pressure calibration in LVPs hinders the broader application of such devices in ultrahigh-pressure studies. This study employs a suite of standard phase transition-based pressure markers—comprising metallic conductors, semiconductors, and minerals—through both in situ and ex situ identification approaches, to establish pressure calibration curves ranging from 0.4 to >30 GPa for various types of LVP installed at the Center for High Pressure Science and Technology Advanced Research (HPSTAR), Beijing, including piston–cylinder, cubic, and multi-anvil presses. The results provide a unified and traceable pressure reference for high-pressure experiments conducted at HPSTAR, while also offering technical guidance and calibration standards for other researchers utilizing similar LVP systems, thereby enabling more consistent comparison between different laboratories. This work facilitates the advancement of LVP research toward broader applications in higher-pressure regimes. en-copyright= kn-copyright= en-aut-name=XuYongjiang en-aut-sei=Xu en-aut-mei=Yongjiang

for ABO-mismatched kidney transplantation: long-term outcomes in a single-center retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background ABO-mismatched kidney transplantation (KTx) expands donor availability but increases risks of antibody-mediated rejection and passenger lymphocyte syndrome (PLS). While rituximab (Rit) potentially mitigates these complications, conventional high-dose regimens (375 mg/m2) elevate infectious and hematologic toxicity. We implemented low-dose Rit induction (200 mg/body) for desensitization in minor/major ABO-mismatched and DSA-positive KTx, evaluating its efficacy and safety over 15-years.
Methods This single-center retrospective cohort (May 2009–April 2024) analyzed 161 adult KTx recipients: Rit (n = 107) and Non-Rit (n = 54) groups. All received tacrolimus, mycophenolate mofetil, prednisolone, and basiliximab; high-risk patients also underwent plasmapheresis. Outcomes included graft survival, biopsy-proven acute rejection, de novo donor-specific antibody (DSA) formation, infection, severe neutropenia, and PLS.
Results 1-year graft survival was 100% in both groups. 5-year death-censored graft survival was 95.8% (Rit) vs 95.9% (Non-Rit), respectively (log-rank P = 0.43). Biopsy-proven acute rejection (7.5% vs 3.7%, P = 0.50) and de novo DSA production were equivalent (Class I: 5.5% vs 2.2%; Class II: 6.6% vs 8.7%; both P = 1.00), with lower mean fluorescent intensity (MFI) in the Rit group. Cytomegalovirus disease, urinary tract infection and fungal infection rates were comparable between both groups. Grade 4 neutropenia was not associated with Rit (OR 2.65; 95% CI 0.63–11.0; P = 0.18). Blood transfusion for hemoglobin declines occurred in 5.6% vs 7.4%, with preserved haptoglobin in all cases, indicating no PLS.
Conclusions Low-dose Rit induction achieves excellent graft survival and effective PLS prevention, without increasing toxicity, supporting its adoption as an optimal desensitization strategy.

kn-title=Spin Transition of Fe3+ in δ-(Al,Fe)OOH and Implication for Mid-Lower Mantle Seismic Heterogeneities en-subtitle= kn-subtitle= en-abstract= kn-abstract=δ-(Al,Fe)OOH is an important water carrier and plays a critical role on Earth's deep water cycle. Lattice parameters of δ-(Al0.89Fe0.11)OOH were measured by synchrotron single-crystal X-ray diffraction at simultaneously high temperature and pressure up to 65 GPa and 800 K in diamond anvil cells. The results reveal that the spin crossover increases from 30 to 37 GPa at 300 K to 36–48 GPa at 700 K. Moreover, at the spin crossover, the KT and VΦ of δ-(Al0.89Fe0.11)OOH occur significant elastic softening, with maximum reductions of 50% on KT and 29% on VΦ at 33 GPa and 300 K to 37% on KT and 23% on VΦ at 41 GPa and 700 K. The anomalous elastic properties of δ-(Al,Fe)OOH at the spin crossover enhance our understanding of local seismic observations anomalies and help identify potential water-rich regions in the mid-lower mantle. 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=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=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=WangYuzhu en-aut-sei=Wang en-aut-mei=Yuzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= 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=State Key Laboratory of Precision Geodesy, University of Science and Technology of China 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=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=6 en-affil=Center for High Pressure Science and Technology Advanced Research kn-affil= affil-num=7 en-affil=Shanghai Advanced Research Institute, Chinese Academy of Sciences kn-affil= affil-num=8 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=spin transition kn-keyword=spin transition en-keyword=δ-(Al,Fe)OOH kn-keyword=δ-(Al,Fe)OOH en-keyword=seismic heterogeneities kn-keyword=seismic heterogeneities 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=53 cd-vols= no-issue=3 article-no= start-page=e2025GL118991 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep-mantle minerals, FeO-rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally-heated diamond anvil cells. Thermoelastic modeling of our results and literature data along a representative areotherm showed that Vp and Vs of FeO-bearing ringwoodite are approximately 7.5% and 11.0% higher than that of the majorite. Our results reveal that velocity profiles of these Martian deep-mantle minerals are more sensitive to variations in the ringwoodite/majorite (Mg/Si) ratio than to thermal and FeO chemical perturbations. Our best-fit velocity model to a recent seismic model by Samuel et al. (2023, https://doi.org/10.1038/s41586-023-06601-8) indicates the Martian mantle contains approximately 67 vol.% ringwoodite and 33 vol.% majorite, suggesting a ringwoodite-rich aggregate in the Martian lowermost solid mantle. The ringwoodite-majorite mantle likely co-evolved with the FeO and other incompatible elements in the molten silicate layer above the Martian core-mantle boundary. en-copyright= kn-copyright= en-aut-name=LiLuo en-aut-sei=Li en-aut-mei=Luo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=RyuYoung Jay en-aut-sei=Ryu en-aut-mei=Young Jay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangDongzhou en-aut-sei=Zhang en-aut-mei=Dongzhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=4 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=5 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=6 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=7 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences, The University of Texas at Austin kn-affil= en-keyword=sound velocity kn-keyword=sound velocity en-keyword=ringwoodite kn-keyword=ringwoodite en-keyword=majorite kn-keyword=majorite en-keyword=Martian mantle kn-keyword=Martian mantle en-keyword=FeO-rich kn-keyword=FeO-rich END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=2 article-no= start-page=e2025GL118147 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Davemaoite Elasticity Reveals Slab‐Induced Heterogeneity in the Mantle Transition Zone en-subtitle= kn-subtitle= en-abstract= kn-abstract=The observed 2%–7% low-shear velocity (VS) anomalies near the subducted slab at the bottom mantle transition zone (MTZ) indicate strong lateral heterogeneity, which is commonly attributed to subducted oceanic crust. However, davemaoite, a major constituent of the subducted oceanic crust, has been poorly constrained in its elasticity, hindering accurate velocity modeling and obscuring the origin of these low-velocity features. Here we report single-crystal elasticity of Ti-bearing davemaoite with the composition of Ca(Si0.57Ti0.43)O3 under high pressure-temperature and found that Ti incorporation significantly reduces velocities and alters the pressure dependence of the shear modulus. Further velocity modeling demonstrated that subducted crusts with varying Ti content have seismic signatures of 1.7(2)–6.8(5)% low-VS at the bottom MTZ, consistent with the observed low-VS structure in the region. These findings highlight the role of slab-derived chemical heterogeneity in generating mantle seismic anomalies and provide new experimental constraints on the structure and dynamics of the deep Earth. en-copyright= kn-copyright= en-aut-name=YuYingxin en-aut-sei=Yu en-aut-mei=Yingxin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhangDongzhou en-aut-sei=Zhang en-aut-mei=Dongzhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 ORCID= en-aut-name=WangDenglei en-aut-sei=Wang en-aut-mei=Denglei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LiJing en-aut-sei=Li en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZhaoChaoshuai en-aut-sei=Zhao en-aut-mei=Chaoshuai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=QianCheng en-aut-sei=Qian en-aut-mei=Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WeiYingzhan en-aut-sei=Wei en-aut-mei=Yingzhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=LiXinyang en-aut-sei=Li en-aut-mei=Xinyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WangYuzhu en-aut-sei=Wang en-aut-mei=Yuzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=2 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=3 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=4 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=5 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=6 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=7 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=8 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=9 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=10 en-affil=State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences kn-affil= affil-num=11 en-affil=State Key Laboratory of High Pressure and Superhard Materials, College of Physics, Jilin University kn-affil= affil-num=12 en-affil=State Key Laboratory of High Pressure and Superhard Materials, College of Physics, Jilin University kn-affil= affil-num=13 en-affil=Shanghai Advanced Research Institute, Chinese Academy of Sciences kn-affil= affil-num=14 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Ti-bearing davemaoite kn-keyword=Ti-bearing davemaoite en-keyword=single-crystal elasticity kn-keyword=single-crystal elasticity en-keyword=slab-induced heterogeneity kn-keyword=slab-induced heterogeneity en-keyword=mantle transition zone kn-keyword=mantle transition zone END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=1850114 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260529 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bee larvae ameliorate andropause-like symptoms via a hormone-independent, antioxidant mechanism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Late-onset hypogonadism (LOH), also known as the male menopause, is characterized by a decline in sexual function as well as various physical and psychological symptoms, including anxiety. Although bee larvae have historically been utilized as a traditional food and medicine, their efficacy and physiological mechanisms of action against male menopausal symptoms remain unclear. In this study, we investigated the effects of bee larvae (BL) on sexual and anxiety-like behaviors using two rodent models of the male menopause: aged rats and castrated mice. In the aged rat model (64 weeks old), dietary BL supplementation for 4 weeks significantly attenuated the age-associated decline in ejaculation frequency compared to controls, while no significant effects were observed on mount or intromission frequencies. Notably, plasma analysis revealed no significant differences in testosterone or dihydrotestosterone levels between the BL and control groups. To elucidate the underlying mechanism, we evaluated sexual function using a castrated mouse model. While BL supplementation did not affect sexual behavior in intact mice, post-castration BL treatment significantly shortened intromission latency without altering mount frequency. In the elevated plus maze test, BL significantly alleviated castration-induced anxiety-like behaviors and improved exploratory activity. Furthermore, in vitro assays demonstrated that the BL extract exerts potent protective effects against oxidative stress, a pathological factor contributing to both erectile dysfunction and anxiety. These results suggest that BL improves erectile function and anxiety via hormone-independent mechanisms, potentially by mitigating oxidative stress in vascular and neural tissues. Thus, bee larvae represent a promising functional food for ameliorating the multi-faceted physical and psychological symptoms associated with male menopause. en-copyright= kn-copyright= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkumuraNobuaki en-aut-sei=Okumura en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtiTakumi en-aut-sei=Oti en-aut-mei=Takumi 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= affil-num=1 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute for Bee Products & Health Science, Yamada Bee Company, Inc. kn-affil= affil-num=3 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=bee larvae kn-keyword=bee larvae en-keyword=late-onset hypogonadism kn-keyword=late-onset hypogonadism en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=sexual behavior kn-keyword=sexual behavior END start-ver=1.4 cd-journal=joma no-vol=130 cd-vols= no-issue=8 article-no= start-page=e2025JB031715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Linking the Spin Transition of Ferric Iron in δ‐(Al,Fe)OOH to Water Storage in the Lower Mantle en-subtitle= kn-subtitle= en-abstract= kn-abstract=As the most massive geochemical reservoir, the lower mantle affects the Earth's budget of volatile elements, including hydrogen or H2O. The properties of minerals in the lower mantle are further affected by changes in the electronic configurations of iron cations, that is, by spin transitions. The feedback between spin transitions and potential storage of H2O in solid hydrous phases in the lower mantle, however, remains unexplored. By combining high-pressure nuclear resonant inelastic X-ray scattering and high-pressure high-temperature X-ray diffraction experiments, we constrained the thermal equation of state of δ-(Al,Fe)OOH, a member of the phase H solid solution. Based on the derived thermal equation of state of δ-(Al,Fe)OOH and the underlying thermodynamic model, we calculate the excess Gibbs free energy that arises from the spin transition of ferric iron in this compound and evaluate the effect on phase equilibria. The results of our analysis show that the spin transition of ferric iron in phase H may significantly reduce the thermodynamic activity and hence the concentration of H2O in a coexisting hydrous melt. As a consequence, nominally anhydrous minerals of the lower mantle may become dehydrated in the presence of phase H. Our analysis further suggests that, under certain conditions, the spin transition may expand the thermal stability of Fe3+-bearing phase H and create a geochemical link between the storage of H2O in phase H and ferric iron in the lower mantle. en-copyright= kn-copyright= en-aut-name=BuchenJohannes en-aut-sei=Buchen en-aut-mei=Johannes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PardoOlivia S. en-aut-sei=Pardo en-aut-mei=Olivia S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DobrosavljevicVasilije V. en-aut-sei=Dobrosavljevic en-aut-mei=Vasilije V. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SturhahnWolfgang en-aut-sei=Sturhahn en-aut-mei=Wolfgang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=CharitonStella en-aut-sei=Chariton en-aut-mei=Stella kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GreenbergEran en-aut-sei=Greenberg en-aut-mei=Eran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToellnerThomas S. en-aut-sei=Toellner en-aut-mei=Thomas S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=JacksonJennifer M. en-aut-sei=Jackson en-aut-mei=Jennifer M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Bayerisches Geoinstitut, Universität Bayreuth kn-affil= affil-num=2 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= affil-num=3 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= affil-num=4 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= affil-num=5 en-affil=Now at Institute for Planetary Materials, Okayama University kn-affil= affil-num=6 en-affil=GSECARS, The University of Chicago kn-affil= affil-num=7 en-affil=GSECARS, The University of Chicago kn-affil= affil-num=8 en-affil=Advanced Photon Source, Argonne National Laboratory kn-affil= affil-num=9 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= en-keyword=spin transition kn-keyword=spin transition en-keyword=phase H kn-keyword=phase H en-keyword=lower mantle kn-keyword=lower mantle en-keyword=high pressure kn-keyword=high pressure en-keyword=equation of state kn-keyword=equation of state en-keyword=phonon density of states kn-keyword=phonon density of states END start-ver=1.4 cd-journal=joma no-vol=115 cd-vols= no-issue= article-no= start-page=107590 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=Long-term neurological and neurocognitive deficits in adults prenatally exposed to methylmercury: Minamata disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Minamata disease, officially recognized in 1956, is a well-known food poisoning event that was caused by the consumption of fish and seafood contaminated with methylmercury. Although patients with congenital Minamata disease (CMD) with severe neurological impairments after birth are widely recognized, few studies have examined the effects of prenatal methylmercury exposure among residents, which is likely at lower levels than in CMD patients. We aimed to investigate the relationship between prenatal methylmercury exposure and subsequent neurological and neurocognitive outcomes. We conducted a cross-sectional study during 2024–2025 among 51 individuals aged approximately 70 years, 27 residents from an existing cohort established in 1970 in Minamata and 24 age-matched individuals who had lived in less-exposed regions. We performed a battery of neurological and neurocognitive tests in both groups and compared the results using multiple linear regression analyses. We also examined the association between intelligence scores obtained in 1970, and intelligence scores obtained in the present investigation, only among exposed participants. We found that exposed individuals had unfavorable neurological and neurocognitive test scores, in comparison with less-exposed controls. Scores on the Montreal Cognitive Assessment, Japanese Edition were 5.91 points lower (95% confidence interval: 3.09 to 8.73) for exposed residents than for the less-exposed group. Moreover, intelligence scores evaluated during exposed participants' adolescence were correlated with their neurocognitive scores in adulthood. Our findings showed that prenatal methylmercury exposure affected subsequent neurological and neurocognitive functions, including among individuals with lower exposure than in CMD patients, and even approximately 70 years after the initial exposure. en-copyright= kn-copyright= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NaganoItsuka en-aut-sei=Nagano en-aut-mei=Itsuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasudaMariko en-aut-sei=Yasuda en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorookaTeruko en-aut-sei=Morooka en-aut-mei=Teruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadoYoko en-aut-sei=Kado en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Non-Profit Organization Hamachidori kn-affil= affil-num=4 en-affil=Clinical Psychology Center, Kawasaki Medical School Hospital kn-affil= affil-num=5 en-affil=Division of Medical Support, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Psychology, Faculty of Letters, Kansai University kn-affil= en-keyword=Environmental pollution kn-keyword=Environmental pollution en-keyword=Methylmercury compounds kn-keyword=Methylmercury compounds en-keyword=Minamata disease kn-keyword=Minamata disease en-keyword=Neurocognitive evaluation kn-keyword=Neurocognitive evaluation en-keyword=Neurological examination kn-keyword=Neurological examination END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=3 article-no= start-page=86 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immediate and delayed effects of thermal stress on fever-associated seizures in children: A time-stratified case-crossover study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to examine the non-linear and delayed effects of thermal stress, measured by the hourly Universal Thermal Climate Index (UTCI), on the risk of pediatric fever-associated seizures (FAS). We conducted a time-stratified case-crossover study in Okayama, Japan (May 2015–March 2023), analyzing 3,201 ambulance-attended FAS cases in children younger than 7 years. Using a distributed lag non-linear model (DLNM) with a 144-h lag, we estimated the association between UTCI and FAS. The analysis revealed a bimodal exposure–response relationship. Moderate Cold Stress (10th percentile, –1.6 °C) was associated with a significant cumulative odds ratio (OR) of 2.22 (95% CI: 1.22–4.06). Risk also increased at the upper range of No Thermal Stress (24.2 °C; cumulative OR 2.74, 95% CI: 1.63–4.63), extending into Moderate Heat Stress (28.7 °C; cumulative OR 2.26, 95% CI: 1.33–3.84). These effects were primarily delayed to 72–96 h for Moderate Cold and reached a peak around 100 h for Moderate Heat. Strong Heat Stress showed immediate but non-significant risk patterns. These findings suggest that infection-mediated pathways likely drive the observed bimodal risk pattern, demonstrate the utility of high-resolution bioclimatic indices, and can inform the development of temperature-specific public health alerts. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamuraYuka en-aut-sei=Yamamura en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Time-stratified Case-crossover study kn-keyword=Time-stratified Case-crossover study en-keyword=Thermal stress kn-keyword=Thermal stress en-keyword=Fever-associated seizures kn-keyword=Fever-associated seizures en-keyword=Universal Thermal Climate Index (UTCI) kn-keyword=Universal Thermal Climate Index (UTCI) en-keyword=Climate change kn-keyword=Climate change en-keyword=Pediatric emergency kn-keyword=Pediatric emergency END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=2 article-no= start-page=18 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-pressure spectroscopic investigation of ε-FeOOH: toward a better understanding of pressure-induced hydrogen-bond symmetrization en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-pressure spectroscopic measurements of ε-FeOOH were conducted up to ~ 65 GPa at room temperature in diamond anvil cells. The pressure evolution of the Raman vibrational modes confirms that a hydrogen-bond-symmetrization-induced phase transition from P21nm to Pnnm occurs at ~ 18 GPa. Infrared (IR) spectroscopic measurements suggest that the Pnnm phase has a disordered hydrogen state, and no spectroscopic evidence for fully centered hydrogen bonds is observed within the investigated pressure range. Above ~ 45 GPa, Fe3+ in ε-FeOOH undergoes a high-spin to low-spin transition as indicated by a reduction of the unit cell volume, together with reductions in IR transmitted and Raman signals. These results demonstrate that ε‑FeOOH preserves a disordered hydrogen‑bond configuration up to at least 45 GPa, whereas δ-AlOOH transforms to a centered hydrogen-bond configuration at ~ 18 GPa. This compositional contrast suggests that Fe‑bearing oxyhydroxides follow a distinct evolution of hydrogen bonding under compression, providing insight into hydrogen behavior in deep Earth materials.

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
Mitochondria are essential for oocyte maturation and early embryonic development, supplying ATP and maintaining mitochondrial DNA (mtDNA) integrity. During oogenesis, mtDNA undergoes dramatic amplification, but the mechanisms and functional significance of this process remain unclear. The purpose of this study was to elucidate the role of mitochondrial transcription factor A (TFAM) in mouse oocytes using an in vitro growth (IVG) system.
Methods
Oocytes at different growth stages were analyzed for mtDNA copy number and expression of mitochondrial biogenesis genes. To assess TFAM function, siRNA targeting Tfam was microinjected into secondary follicles, which were then cultured for 12 days under IVG conditions. Following culture, oocyte growth, mtDNA content, mitochondrial membrane potential, and developmental competence after in vitro fertilization (IVF) were evaluated.
Results
mtDNA copy number increased nonlinearly during oocyte growth, with a pronounced rise at the secondary follicle stage accompanied by TFAM upregulation. TFAM knockdown reduced mtDNA copy number and mitochondrial function without affecting oocyte size or meiotic maturation, but significantly decreased blastocyst formation and total cell numbers per blastocyst.
Conclusions
TFAM-mediated mtDNA replication is crucial for mitochondrial function and developmental competence of IVG-derived oocytes, underscoring its importance in early embryonic development. en-copyright=

kn-article= en-subject= kn-subject= en-title= kn-title=Tailored Management of Anomalous Systemic Arterial Supply to the Basal Segment of the Lung: A Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=INTRODUCTION: Parenchyma-preserving strategies for anomalous systemic arterial supply to the basal segment of the lung have gained increasing attention. However, pulmonary infarction of the preserved lung has been reported, and clear criteria for selecting the optimal treatment have yet to be established. We report 2 cases in which detailed preoperative imaging informed tailored management—right posterior basal segmentectomy in 1 patient and endovascular embolization of the aberrant artery in the other—both without postoperative complications. A review of the relevant literature is also provided, with an emphasis on potential selection criteria.
CASE PRESENTATION: Case 1: A 20-year-old asymptomatic woman was referred after an abnormal screening chest radiograph. CT demonstrated an aberrant artery arising from the abdominal aorta supplying the right posterior basal segment (S10) with a large intravascular thrombus. The pulmonary artery showed hypoplasia limited to A10, while the other branches were normal, and no parenchymal congestion was identified. Following resection of the aberrant artery, robot-assisted right S10 segmentectomy was performed. The postoperative course was uneventful, and the patient was discharged on POD 6. Case 2: A 27-year-old woman was incidentally diagnosed on CT for an unrelated indication. An aberrant artery arising from the descending thoracic aorta supplied the left basal segment. Pulmonary arterial branches were preserved, with only minimal congestion in S9-10. Angiography revealed no evidence of an arteriovenous fistula. As surgical lung resection was considered unnecessary, coil embolization of the aberrant artery was performed. No complications occurred, and the patient was discharged on day 3 after the procedure.
CONCLUSIONS: In patients with anomalous systemic arterial supply to the basal segment of the lung, when pulmonary arterial branches are preserved and background parenchymal congestion is minimal, parenchyma-sparing approaches should be considered. en-copyright= kn-copyright= en-aut-name=MoriShunsuke en-aut-sei=Mori en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

kn-title=Treatment strategies for pulmonary arterial hypertension associated with adult congenital heart diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
The number of patients with adult congenital heart disease (ACHD) is gradually increasing worldwide due to advances in surgical techniques and pharmacological therapies. ACHD can lead to pulmonary arterial hypertension (PAH), and treatment strategies for PAH associated with ACHD have also evolved.

Areas covered
Several PAH-targeted drugs including endothelin receptor antagonists, phosphodiesterase type 5 inhibitors, soluble guanylate cyclase stimulators, and prostacyclin analogs are available for treatment of PAH. In this review, we summarized the current evidence regarding the use of PAH-targeted drugs in patients with PAH associated with ACHD. We also propose a ‘treat and repair’ strategy, which involves initial medical treatment to improve PAH followed by surgical or interventional repair of the systemic-to-pulmonary shunt. A PubMed literature search was conducted from 2000 to 2025.

Expert opinion
In cases of PAH associated with a systemic-to-pulmonary cardiac shunt, advanced PAH-targeted drugs can improve hemodynamics, and reduce the risk of cardiac defect repair and further improvement in PAH. The treat and repair strategy represents a promising therapeutic approach for PAH patients associated with systemic-to-pulmonary shunts. en-copyright= kn-copyright= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 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=5 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Adult congenital heart diseases kn-keyword=Adult congenital heart diseases en-keyword=pulmonary arterial hypertension kn-keyword=pulmonary arterial hypertension en-keyword=PAH-targeted drugs kn-keyword=PAH-targeted drugs en-keyword=systemic-to-pulmonary shunt kn-keyword=systemic-to-pulmonary shunt en-keyword=treat and repair strategy kn-keyword=treat and repair strategy END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=e004185 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=Predictive value of simple echocardiographic parameters for screening pulmonary hypertension under the revised definition: a study for general hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The current guideline recommends a peak tricuspid regurgitation velocity (TRV) ≥2.9 m/s on echocardiography for pulmonary hypertension (PH) screening; however, this threshold was based on the previous PH definition (mean pulmonary arterial pressure (mPAP) ≥25 mm Hg) and derived largely from PH referral centres.
Methods We retrospectively analysed 755 patients who underwent both transthoracic echocardiography and right heart catheterisation at two general hospitals. The discrimination of peak TRV and estimated right atrial pressure (eRAP), derived from inferior vena cava diameter and respiratory variation, for screening for PH was assessed by receiver operating characteristic curve analysis. Optimal cut-off values were determined with the Youden Index.
Results The c-statistic for peak TRV in detecting PH was 0.82 (95% CI 0.79 to 0.85). An optimal cut-off of 2.7 m/s provided higher sensitivity (72%) than the conventional 2.9 m/s threshold (60%) while maintaining high specificity (82%). In 681 patients with available TRV and eRAP data, adding eRAP improved discrimination compared with TRV alone (c-statistic 0.83 vs 0.80; net reclassification improvement=0.14, p=0.002). eRAP ≥5 mm Hg was associated with a higher risk of PH, and the combination of elevated TRV and eRAP yielded the strongest association.
Conclusion For screening under the revised PH definition, a peak TRV of 2.7 m/s is suggested as the optimal cut-off. Although TRV alone showed good discriminative performance, combining it with eRAP further improved diagnostic accuracy using simple echocardiographic measures. en-copyright= kn-copyright= en-aut-name=FukudaYoshitake en-aut-sei=Fukuda en-aut-mei=Yoshitake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TayaSatoshi en-aut-sei=Taya en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=DohiYoshihiro en-aut-sei=Dohi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of 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, Kure Kyosai Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=302 cd-vols= no-issue=6 article-no= start-page=113085 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=A photoactivatable Cre-loxP system for spatiotemporal genetic manipulation in mouse taste buds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Conventional genetic approaches, including global gene KO and conditional KO strategies such as the Cre-loxP system, have some limitations arising from systemic effects or insufficient temporal resolution. The recently developed photoactivatable Cre (PA-Cre) system may have a potential to improve spatiotemporal control of gene manipulation. In this study, we established and validated the feasibility of the PA-Cre system using taste buds as a model. We generated TRE-PA-Cre:R26-rtTA/tdTomato mice to evaluate blue-light-induced Cre recombinase activity. Through systematic optimization of illumination parameters, we found that a single session of blue-light-illumination resulted in limited recombination efficiency, whereas a multisession illumination strategy markedly increased recombination efficiency. To further assess the utility of the PA-Cre system for gene KO, we generated TRE-PA-Cre:R26-rtTA:Tas1r3-flox mice and targeted a taste-related gene Tas1r3. Genomic DNA quantitative PCR and reverse transcription-quantitative PCR both showed partial reductions in Tas1r3 at the DNA and mRNA levels, respectively. Behavioral assays further revealed a selective decrease in sensitivity to sweet and umami stimuli. Together, these findings demonstrate PA-Cre-mediated gene manipulation in taste buds and establish a practical optical activation paradigm, providing a high-spatiotemporal-resolution tool for investigating gene function in optically targeted regions. en-copyright= kn-copyright= en-aut-name=ZuoYu en-aut-sei=Zuo en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaYasuhiro en-aut-sei=Yamada en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoTomoka en-aut-sei=Takao en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaradaTakeshi en-aut-sei=Takarada en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KokabuShoichiro en-aut-sei=Kokabu en-aut-mei=Shoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Molecular Pathology, Graduate School of Medicine and Faculty of Medicine, The University of Tokyo kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Biochemistry, Kyushu Dental University kn-affil= affil-num=8 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cre-loxP kn-keyword=Cre-loxP en-keyword=genetic manipulation kn-keyword=genetic manipulation en-keyword=mouse kn-keyword=mouse en-keyword=photoactivatable Cre kn-keyword=photoactivatable Cre en-keyword=spatiotemporal kn-keyword=spatiotemporal en-keyword=taste kn-keyword=taste END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=105 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Programmable synthesis of alkaloidal frameworks integrating Michael acceptor generates covalent probes for targeting POLE3 in HBV replication en-subtitle= kn-subtitle= en-abstract= kn-abstract=The growing need for effective HBV treatments and lead compounds with novel mechanisms prompted us to explore synthetic strategies for generating skeletally diverse alkaloidal Michael acceptors. Our approach uniquely embeds Michael acceptors directly within multicyclic alkaloid-inspired frameworks, exploiting the azepinoindole scaffold—a privileged structure in indole alkaloids. A single-step assembly between the versatile intermediate 13 with methyl propiolate 14 or its derivatives enabled the rapid and divergent synthesis of six alkaloidal Michael acceptors (15–20). This strategy facilitated systematic diversification of three-dimensional functional group arrangements and precise tuning of the electronic and steric properties of the embedded α,β-unsaturated carbonyl moieties. The optimal hit 15 inhibited hepatitis B surface antigen (HBsAg) production with an IC50 of 2.48 μM and significantly reduced levels of covalently closed circular DNA (cccDNA), the master template of HBV. Unlike existing nucleoside/nucleotide-based anti-HBV drugs that primarily inhibit reverse transcription, the alkaloidal Michael acceptor 15 suppressed both cccDNA and relaxed circular DNA (rcDNA) levels, suggesting a potential pathway toward a functional HBV cure. Our study also streamlined the target identification by leveraging the covalent binding properties of the Michael acceptors and the operational simplicity of biotin- or fluorescent-tag attachment via a pre-installed alkyne moiety. Competitive pull-down experiments identified several potential target proteins, involving DNA polymerase epsilon subunit 3 (POLE3). Notably, the alkaloidal Michael acceptor 15 was demonstrated to covalently modify Cys51 in POLE3, providing new insights into virus–host interactions and opening novel avenues for targeted anti-HBV therapies. This approach represents a significant advance beyond traditional screening methods and underscores the potential of skeletally diverse alkaloidal Michael acceptors in antiviral drug development. en-copyright= kn-copyright= en-aut-name=KanekoNobuto en-aut-sei=Kaneko en-aut-mei=Nobuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HimenoMisao en-aut-sei=Himeno en-aut-mei=Misao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiYuhi en-aut-sei=Kobayashi en-aut-mei=Yuhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanifujiRyo en-aut-sei=Tanifuji en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KubotaHiroki en-aut-sei=Kubota en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MizoguchiHaruki en-aut-sei=Mizoguchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MuroiMakoto en-aut-sei=Muroi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiTakehiro en-aut-sei=Suzuki en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugiyamaMasaya en-aut-sei=Sugiyama en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DohmaeNaoshi en-aut-sei=Dohmae en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OsadaHiroyuki en-aut-sei=Osada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KidoTaketomo en-aut-sei=Kido en-aut-mei=Taketomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiyajimaAtsushi en-aut-sei=Miyajima en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OguriHiroki en-aut-sei=Oguri en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Science, The University of Tokyo kn-affil= affil-num=2 en-affil=Department of Developmental Medical Sciences, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Science, The University of Tokyo kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Science, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Tokyo University of Agriculture and Technology kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Centre for Sustainable Resource Science, RIKEN kn-affil= affil-num=8 en-affil=Centre for Sustainable Resource Science, RIKEN kn-affil= affil-num=9 en-affil=Department of Viral Pathogenesis and Control, National Institute of Global Health and Medicine, Japan Institute for Health Security kn-affil= affil-num=10 en-affil=Centre for Sustainable Resource Science, RIKEN kn-affil= affil-num=11 en-affil=Centre for Sustainable Resource Science, RIKEN kn-affil= affil-num=12 en-affil=Laboratory of Cell Growth and Differentiation, Institute for Quantitative Biosciences, The University of Tokyo kn-affil= affil-num=13 en-affil=Laboratory of Cell Growth and Differentiation, Institute for Quantitative Biosciences, The University of Tokyo kn-affil= affil-num=14 en-affil=Department of Chemistry, Graduate School of Science, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue= article-no= start-page=e2026GL122541 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260520 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Discovery of Repeating Shallow Moonquakes in the Apollo Lunar Seismic Data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Shallow moonquakes have been considered unique due to their large magnitudes and affinities with intraplate earthquakes. However, the small number of detections (<80 events) has prevented detailed characterization. In this study, I identified a pair of repeating shallow moonquakes by analyzing a recently updated moonquake data set. Relative-phase assessment revealed that these events exhibit a consistent fault-slip direction despite their occurrence at opposite tidal phases. This differs from what was observed for repeating deep moonquakes, which are closely related to tides, implying that tidal stress does not dominantly control fault-slip initiation of the repeating shallow moonquakes. Also, the identified repeating shallow moonquakes exhibit a similar relationship between seismic moment and the spatial scale of the slip area to earthquakes. This may indicate that earthquake-like fault physics operates on the Moon, albeit with a different driving mechanism than on Earth. en-copyright= kn-copyright= en-aut-name=OnoderaKeisuke en-aut-sei=Onodera en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=lunar seismology kn-keyword=lunar seismology en-keyword=tectonism kn-keyword=tectonism en-keyword=Moon kn-keyword=Moon en-keyword=Apollo kn-keyword=Apollo en-keyword=planetary seismology kn-keyword=planetary seismology en-keyword=fault physics kn-keyword=fault physics END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page= 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=Second-look endoscopy does not reduce delayed bleeding after endoscopic papillectomy: a multicenter propensity score-matched analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Delayed bleeding is a frequent and serious complication after endoscopic papillectomy (EP). Second-look endoscopy (SLE) is often scheduled on the following day for wound assessment and prophylactic hemostasis, but its clinical value remains unclear.
Objectives: This study evaluated the effectiveness of SLE in preventing delayed bleeding after EP.
Design: This study was a multicenter, retrospective cohort study.
Methods: We retrospectively reviewed 132 consecutive patients who underwent EP at nine high-volume centers between 2003 and 2024 (SLE group, n = 73; non-SLE group, n = 59). Propensity score matching was performed to balance baseline characteristics. The primary outcome was delayed bleeding, and secondary outcomes were risk factors, the impact of prophylactic hemostasis during SLE, and hospital stay.
Results: After matching, 43 patients were included in each group. The incidence of delayed bleeding did not differ between the SLE and non-SLE groups (14% vs 9%, p = 0.50). Multivariate analysis identified a lack of preventive clipping closure as the only independent risk factor (odds ratio 15, 95% confidence interval 1.3–177, p = 0.030). Prophylactic hemostasis during SLE did not reduce bleeding but was associated with prolonged hospitalization (13 vs 9 days, p = 0.012).
Conclusion: Routine SLE after EP does not reduce delayed bleeding. Moreover, prophylactic hemostasis in asymptomatic patients may unnecessarily prolong hospitalization. Hemostasis should be reserved for patients who develop clinical signs of bleeding. en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei=

Study on Order Assignment in E-Commerce en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examines the relationship between a multiplicatively weighted (MW-) Voronoi diagram and the Huff model. A mathematical comparison demonstrates that the models are structurally equivalent when the Huff model is deterministic and the distance decay parameter λ takes a specific value. This theoretical finding was empirically validated using real-world e-commerce order assignment data. The experiments demonstrate the distinct strengths of each model. The Huff model enables the flexible balancing of competing objectives through parameter adjustment, whereas the MW-Voronoi diagram provides geometric clarity in the interpretation of territories. We conclude that the selection of the two models should be guided by the problem objectives, depending on whether probabilistic flexibility or deterministic spatial partitioning is required. en-copyright= kn-copyright= en-aut-name=KawamotoTakaki en-aut-sei=Kawamoto en-aut-mei=Takaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasuikeTakashi en-aut-sei=Hasuike en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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 Industrial and Management Systems Engineering, School of Creative Science and Engineering, Waseda University kn-affil= en-keyword=multiplicatively weighted Voronoi diagram kn-keyword=multiplicatively weighted Voronoi diagram en-keyword=Huff model kn-keyword=Huff model en-keyword=order assignment algorithm kn-keyword=order assignment algorithm END start-ver=1.4 cd-journal=joma no-vol=373 cd-vols= no-issue= article-no= start-page=fnag055 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=Intercellular signal transduction within the mother cell compartment during Bacillus subtilis sporulation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intercellular signaling contributes to the spatiotemporal regulation of gene expression during sporulation in Bacillus subtilis. The mother cell transcription factor σE is initially produced as an inactive precursor protein pro-σE and activated by the processing enzyme SpoIIGA in response to the forespore-produced putative signaling molecule SpoIIR. However, the mechanism underlying the SpoIIR-mediated signal transduction remains poorly understood. In this study, we showed that the spoIIR-positive, spoIIGA-deleted strain was able to induce SpoIIGA-dependent pro-σE processing in co-cultured spoIIR-deleted, spoIIGA-positive strains. This signaling was dependent on SpoIIR expression and did not involve DNA transfer. Extracellular materials including secreted proteins and membrane vesicles were unlikely to be involved in this signaling pathway. Interestingly, cessation of co-incubation shaking enhanced the signaling, while the addition of membrane-solubilizing detergent abolished it. In addition, SpoIIR signaling did not necessitate release from the forespore membrane or extracellular translocation. A SpoIIR variant lacking the putative signal peptide-like hydrophobic domain produced solely in the mother cell compartment was still able to activate pro-σE. Overall, the study findings suggested that the forespore-produced SpoIIR is neither secreted nor externally translocated. Instead, SpoIIR appeared to be transferred into the mother cell compartment and interacts with the SpoIIGA cytoplasmic domain to trigger pro-σE processing. en-copyright= kn-copyright= en-aut-name=KuwabaraNobuki en-aut-sei=Kuwabara en-aut-mei=Nobuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AnzueMasato en-aut-sei=Anzue en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoTsutomu en-aut-sei=Sato en-aut-mei=Tsutomu 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=Department of Frontier Bioscience, Hosei University kn-affil= affil-num=2 en-affil=Department of Frontier Bioscience, Hosei University kn-affil= affil-num=3 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Frontier Bioscience, Hosei University kn-affil= affil-num=5 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= en-keyword=Bacillus subtilis kn-keyword=Bacillus subtilis en-keyword=sporulation kn-keyword=sporulation en-keyword=sigma cascade kn-keyword=sigma cascade en-keyword=intercellular signal transduction kn-keyword=intercellular signal transduction END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=9 article-no= start-page=6225 end-page=6235 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ion-Conductive Vitrimers Based on Backbone-Type Triazolium Poly(Ionic Liquid)s: Counterion-Dependent Dynamics and Backbone Flexibility en-subtitle= kn-subtitle= en-abstract= kn-abstract=To simultaneously achieve high ionic conductivity and recyclability, vitrimers were prepared using backbone-type triazolium poly(ionic liquid)s (TPILs) that integrate ionic transport and dynamic network rearrangement via trans-N-alkylation. TPIL elastomers bearing I–, BF4–, PF6–, and TFSI– counteranions were synthesized from “clickable” ionic liquid monomers, and their glass transition temperature (Tg), ionic conductivity, and vitrimeric dynamics were compared. Only the I–-based network exhibited stress relaxation at 170 °C, indicating that nucleophilic anions are important for bond exchange. However, a trade-off was observed between ionic transport and dynamic network rearrangement. We overcome this trade-off by mixing anions. Mixed-anion TPIL elastomers using I– and TFSI– exhibited lower Tg and higher ionic conductivity than I–-based elastomer, while still maintaining vitrimer-like relaxation. Rheological analysis revealed a decoupling between segment relaxation and bond exchange dynamics in vitrimer-like elastomers. The design combining flexible polymer backbones and mixed-anion engineering can create recyclable, highly conductive polymer electrolyte networks. en-copyright= kn-copyright= en-aut-name=TsunekawaHikari en-aut-sei=Tsunekawa en-aut-mei=Hikari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoAtsushi en-aut-sei=Matsumoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IidaYuya en-aut-sei=Iida en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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 and Biotechnology, Graduate School of Engineering, University of Fukui kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= en-keyword=dynamic covalent bond kn-keyword=dynamic covalent bond en-keyword=poly(ionic liquid) kn-keyword=poly(ionic liquid) en-keyword=vitrimer kn-keyword=vitrimer en-keyword=trans-N-alkylation kn-keyword=trans-N-alkylation en-keyword=conductivity kn-keyword=conductivity en-keyword=anion kn-keyword=anion END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=ra.2025-0153 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=Current Status of Middle Meningeal Artery Embolization for Chronic Subdural Hematoma: An International Perspective Including Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Middle meningeal artery embolization (MMAE) for chronic subdural hematoma (CSDH) is gaining global prevalence as a minimally invasive treatment aimed at serving as an adjunct to or method of avoiding surgery; however, its optimal positioning remains unclear. This study outlines the current status of MMAE in Japan, Germany, and the United States based on nationwide survey reports, recently published consensus guidelines, and meta-analyses including randomized controlled trials (RCTs) reported in the New England Journal of Medicine (NEJM; EMBOLISE, STEM, and MAGIC-MT) and examines its efficacy and limitations. Real-world clinical data from Japan, Germany, and the United States indicate that MMAE is primarily used as an adjunctive therapy following surgery for older and high-risk or recurrent cases, or as a stand-alone therapy in selected cases to safely reduce the risk of recurrence and reoperation. While a multidisciplinary consensus statement takes a cautious stance that limits MMAE to recurrent or inoperable cases such as those at high risk associated with interrupting antithrombotic medication, the Society of Vascular and Interventional Neurology guidelines published after the RCTs strongly recommend the concurrent use of MMAE with standard therapy in de novo cases. Meta-analyses integrating the 3 NEJM trials and other RCTs showed that MMAE suppressed recurrence and reoperation versus standard treatment, with particularly pronounced effects in the nonsurgical (conservative treatment) group; however, the additive effect was limited in the surgical adjunct group. No improvement in functional outcomes (modified Rankin Scale score) was observed. Cost-effectiveness analyses suggest that, while MMAE reduces reoperations, routine implementation for all cases is difficult to justify economically because of high procedural costs, indicating the need to narrow the indication to populations at high risk of recurrence. In conclusion, although MMAE is an effective treatment option, the current evidence does not support its uniform introduction in all patients with CSDH. Thus, it is necessary to individualize and adapt the indications for specific patient subgroups, such as those at high risk of recurrence or those for whom surgery is difficult. Finally, we propose a pragmatic treatment strategy for MMAE stratified by disease stage (de novo vs. recurrent) and clinical severity to guide the individualized selection of adjunctive and stand-alone embolization. en-copyright= kn-copyright= en-aut-name=KawakamiMasato en-aut-sei=Kawakami en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=KimuraRyu en-aut-sei=Kimura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SoutomeYuta en-aut-sei=Soutome en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaJuntaro en-aut-sei=Fujita en-aut-mei=Juntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BabaFukiko en-aut-sei=Baba en-aut-mei=Fukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= 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 Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=middle meningeal artery embolization kn-keyword=middle meningeal artery embolization en-keyword=chronic subdural hematoma kn-keyword=chronic subdural hematoma en-keyword=current status kn-keyword=current status 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=20260519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Incidence of B-cell Malignancies in Patients with Lung Cancer Receiving PD-1 Blockade Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Many patients with various cancer types have received immune checkpoint inhibitors (ICI) worldwide since their approval, and novel unexpected complications from their long-term use are apparent. We identified some cases of B-cell lymphoma occurring during PD-1 blockade therapy as such unexpected complications. In this study, we aimed to evaluate the incidence of hematologic malignancies in patients with lung cancer receiving PD-1 blockade therapy and to elucidate the mechanisms underlying the progression of these malignancies.
Experimental Design: We performed IHC staining on the clinical samples from patients with B-cell lymphoma that developed during PD-1 blockade therapy and analyzed large-scale real-world datasets. We further investigated the underlying mechanisms through in vitro and in vivo experiments.
Results: A higher incidence of B-cell malignancies has been observed in patients with lung cancer treated with PD-1 blockade therapies based on large-scale real-world data analyses (n = 15,670). The identified lymphomas had a large amount of CD4+ T follicular helper (TFH) cell infiltration. In addition, PD-1 blockade activated PD-1+ TFH cells, which promoted lymphoma proliferation via the IL4/IL4R, IL21/IL21R, and CD40L/CD40 axes. Notably, the lymphomas exhibited high expression of IL4R, IL21R, and CD40.
Conclusions: Our findings highlight the need for careful monitoring and consideration of the potential B-cell malignancy complications in clinical settings in which ICIs are used. en-copyright=

candidate therapies for multiple sclerosis: inverse signal analysis using the FDA adverse event reporting system and preclinical validation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Alterations in bile acid metabolism have been observed in individuals with multiple sclerosis (MS), yet the therapeutic implications of bile acid supplementation remain uncertain.
Methods: We conducted a two-stage study integrating pharmacovigilance analysis with preclinical validation to evaluate bile acid derivatives as candidate therapies for MS. A disproportionality analysis of the FDA Adverse Event Reporting System (FAERS; Q4/2003–Q2/2025) was performed to identify inverse associations between MS and bile acid preparations. The effects of ursodeoxycholic acid (UDCA) and obeticholic acid (6-ECDCA) were evaluated in a therapeutic experimental autoimmune encephalomyelitis (EAE) model, with treatment initiated after disease onset.
Results: Among 13,734,539 FAERS reports, 75,659 involved MS. Inverse associations were identified for UDCA (odds ratio [OR]: 0.197, 95% confidence interval [CI]: 0.117–0.333) and 6-ECDCA (OR: 0.128, 95% CI: 0.041–0.396). In the EAE model, UDCA was associated with lower clinical scores at the peak (day 18) and late phases (days 26–28), whereas 6-ECDCA showed only a non-significant trend toward improvement at day 28.
Conclusion: This two-stage investigation highlights the potential utility of pharmacovigilance-guided approaches for identifying therapeutic candidates. Bile acid derivatives, particularly UDCA, are biologically plausible candidates meriting further investigation in the context of MS. en-copyright= kn-copyright= en-aut-name=AsadaMizuho en-aut-sei=Asada en-aut-mei=Mizuho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MikamiTakahisa en-aut-sei=Mikami en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GodaMitsuhiro en-aut-sei=Goda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SonodaYuhei en-aut-sei=Sonoda en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NiimuraTakahiro en-aut-sei=Niimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=ChumaMasayuki en-aut-sei=Chuma en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UesawaYoshihiro en-aut-sei=Uesawa en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshizawaKeisuke en-aut-sei=Ishizawa en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Medical Molecular Informatics, Meiji Pharmaceutical University kn-affil= affil-num=2 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=3 en-affil=Department of Neurology, Massachusetts General Hospital kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Pharmacology and Therapeutics, Tokushima University Graduate School of Biomedical Sciences kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy and Pharmacology, Asahikawa Medical University and University Hospital kn-affil= affil-num=9 en-affil=Department of Medical Molecular Informatics, Meiji Pharmaceutical University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= en-keyword=Bile acids kn-keyword=Bile acids en-keyword=Multiple sclerosis kn-keyword=Multiple sclerosis en-keyword=Database analysis kn-keyword=Database analysis en-keyword=Drug repositioning kn-keyword=Drug repositioning en-keyword=Experimental autoimmune encephalomyelitis kn-keyword=Experimental autoimmune encephalomyelitis END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=48 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adverse events of romidepsin versus tucidinostat for peripheral T-cell lymphoma: a pharmacovigilance study using the Japanese adverse drug event report database en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of lymphomas with poor prognosis, particularly in patients with relapsed or refractory (R/R) disease. Romidepsin and tucidinostat are histone deacetylase inhibitors used to treat R/R PTCL. No head-to-head post-marketing surveillance studies have compared adverse events (AEs) between the two agents. In this brief report, the AE profiles of romidepsin and tucidinostat were compared using the Japanese Adverse Drug Event Report (JADER) database to facilitate their differentiation and promote the management of AEs.
Methods We conducted a descriptive analysis using data from the JADER database from April 2018 to July 2025. The reported AEs for romidepsin and tucidinostat were extracted and classified according to preferred terms (PTs) and system organ classes (SOCs). Reporting odds ratios with 95% confidence intervals were calculated to compare the AE profiles between the groups.
Results In total, 998,397 reports were analysed for all drugs, including 323 for romidepsin and 753 for tucidinostat. Compared with all drugs, both agents showed significant disproportionality signals in four SOCs: Blood and lymphatic system disorders; General disorders and administration site conditions; Investigations; and Neoplasms benign, malignant and unspecified. Romidepsin exhibited additional significant signals in six SOCs: Cardiac disorders, Eye disorders, Gastrointestinal disorders, Immune system disorders, Infections and infestations, and Metabolism and nutrition disorders. Direct comparison between the two agents revealed broader AE profiles for romidepsin, with AEs more frequently reported in eight SOCs, whereas tucidinostat showed AEs in only two SOCs. Romidepsin was associated with AEs more frequently reported in several PTs, including atrial fibrillation and gastrointestinal toxicities, such as constipation, tumour lysis syndrome, hepatotoxicity, and peripheral neuropathy, which was consistent with the results at the SOC level. In contrast, several significant PTs for tucidinostat were observed in General disorders and administration site conditions and Investigations.
Conclusions The Japanese real-world pharmacovigilance analysis showed differences in the AE profiles between romidepsin and tucidinostat. These differences in safety profiles may be useful for treatment selection and AE management in routine clinical practice among patients with R/R PTCL. Further studies are warranted to confirm these findings and better characterise the safety profiles of these agents. en-copyright= kn-copyright= en-aut-name=TakatsuNao en-aut-sei=Takatsu en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoJun en-aut-sei=Matsumoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkaYurie en-aut-sei=Oka en-aut-mei=Yurie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaiTomonori en-aut-sei=Sakai en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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=8 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Clinical Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Romidepsin kn-keyword=Romidepsin en-keyword=Tucidinostat kn-keyword=Tucidinostat en-keyword=Adverse event kn-keyword=Adverse event en-keyword=JADER kn-keyword=JADER en-keyword=Pharmacovigilance kn-keyword=Pharmacovigilance END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=9 end-page= 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=Relationship Between Numbers of Patients Registered and Procedures Performed at Lung Transplantation Centers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Recently, there has been a dramatic increase in deceased lung transplantation (DLT) procedures performed in Japan. However, there is concern that the number of transplantations may reach the limit of capacity in some centers. The present study was conducted to analyze the relationship between the numbers of individuals registered for DLT by the Japan Organ Transplantation Network (JOT) and procedures subsequently performed at lung transplantation centers. Methods: Using a database and registry reports provided by the Japanese Society of Lung and Heart-lung Transplantation, the numbers of individuals registered in the JOT and DLT procedures performed from January 2014 to December 2023 were analyzed. Results: The number of registrations was found to be correlated with the number of DLTs, with the coefficient of determination (R2) 0.962 and slope of the regression line (X coefficient) 0.407. The facility with the greatest number of registrations, with a registration-to-transplantation ratio of 0.353, was identified as an outlier (p < 0.05) and excluded from analysis. This exclusion increased both the correlation coefficient value to 0.986 and X coefficient value to 0.461. Conclusions: The present analysis showed that the number of DLTs was well correlated with number of registrations at each of the transplantation facilities. Both registration and transplantation numbers have increased in the recent decade. The facility with the highest number of registrations showed a lower registration-to-transplantation ratio, because the increase in registrations outpaced the number of transplantations. en-copyright=

photon-counting detector CT for temporal bone imaging: phantom and clinical studies with helical acquisition en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To determine the extent of possible dose reduction with photon-counting detector computed tomography (PCD-CT) while maintaining image quality equivalent to that of energy-integrating detector CT (EID-CT) images at standard dose in the temporal bone.
Materials and methods: PCD-CT and EID-CT imaging quality were compared by visual evaluation of clinical temporal bone images and visual scores with Welch’s t-test at standard dose. A head phantom was used to evaluate imaging quality under dose reduction. The detectability index (d’) of the PCD-CT images at various dose levels and the EID-CT images at standard dose was evaluated. Dose reduction limit with PCD-CT used in the subsequent clinical evaluation was determined as the lowest dose with image quality equal to or better than EID-CT. The clinical equivalence of PCD-CT image quality at the determined reduced dose to that with EID-CT at standard dose was evaluated using visual scores. Equivalence was determined if the 95% confidence intervals of differences did not exceed the equivalence margin of ±1.
Results: At standard doses, PCD-CT images demonstrated significantly higher visual scores than EID-CT images (3.73 vs. 2.56 for incudomalleolar joint, 3.75 vs. 2.63 for stapes, 3.54 vs. 2.52 for cochlea, and 3.58 vs. 2.46 for facial nerve canal; all P 0.001). In the phantom study, the d’ value was 0.15 with EID-CT at standard dose and was 0.12 and 0.17 with PCD-CT at 25% and 50% of the standard dose, respectively. Clinically, the mean visual scores of PCD-CT images at 50% of the standard dose were equivalent to EID-CT images at standard dose in all regions (3.58 vs. 3.12 for incudomalleolar joint, 3.46 vs. 3.19 for stapes, 3.50 vs. 3.08 for cochlea, 3.58 vs. 3.27 for facial nerve canal).
Conclusion: PCD-CT may preserve image quality even at 50% of the standard dose in the temporal bone. en-copyright= kn-copyright= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NakamuraYuko en-aut-sei=Nakamura en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HigakiToru en-aut-sei=Higaki en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro 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=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AwaiKazuo en-aut-sei=Awai en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Diagnostic Radiology, Hiroshima University kn-affil= affil-num=4 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University 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, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Diagnostic Radiology, Hiroshima University kn-affil= affil-num=14 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=PCD-CT kn-keyword=PCD-CT en-keyword=EID-CT kn-keyword=EID-CT en-keyword=Dose reduction kn-keyword=Dose reduction en-keyword=Temporal bone CT kn-keyword=Temporal bone CT en-keyword=Incudomalleolar joint kn-keyword=Incudomalleolar joint en-keyword=Stapes kn-keyword=Stapes END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=e70136 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exogenous Glutathione and Nitric Oxide Improve Waterlogging Stress Tolerance in Maize en-subtitle= kn-subtitle= en-abstract= kn-abstract=Maize (Zea mays L.) is one of the major grain crops worldwide that is particularly vulnerable to waterlogging (WL) stress. Glutathione (GSH) and nitric oxide (NO) are known to protect plants from a variety of abiotic stresses; however, their potential for improving WL tolerance in maize remains unexplored. The present study examined the impact of exogenously applied GSH and NO on maize plants exposed to WL-stress. Our findings revealed that GSH + NO-treated waterlogged maize plants grew better and produced more biomass than only WL-stressed plants. The improved performance of GSH + NO-sprayed WL-stressed maize seedlings was supported by the increased root dry and fresh weight, shoot length, shoot dry and fresh weight, chlorophyll a, chlorophyll b, and carotenoid content. Exogenous GSH and NO treatments significantly enhanced the amounts of leaf proline, leaf soluble sugars, and total protein in maize seedlings, suggesting adaptive metabolic reprogramming under stress. The increased malondialdehyde (MDA) levels and accumulation of hydrogen peroxide (H2O2) in maize leaves and roots revealed that WL caused significant oxidative damage. Exogenous GSH, NO individually, and combinedly significantly decreased total H2O2 and MDA contents in both leaves and roots. Exogenous GSH and NO reduced oxidative stress by increasing peroxidase activity, ascorbic acid, and anthocyanin content in maize leaf and root tissues. Our findings emphasize the possible relevance of GSH and NO, simultaneously and individually, in enhancing adaptive mechanisms in maize seedlings for reducing WL-induced damage. Although the GSH + NO-mediated approach shows promise for mitigating WL-stress in maize under controlled conditions, further field-based investigations are required to validate its practical applicability. en-copyright= kn-copyright= en-aut-name=AngonProdipto Bishnu en-aut-sei=Angon en-aut-mei=Prodipto Bishnu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Tahjib‐Ul‐ArifMd. en-aut-sei=Tahjib‐Ul‐Arif en-aut-mei=Md. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JahanMd.

In this population, vasodilator-based therapies effective in other forms of PAH have shown limited benefit, and no disease-modifying treatment has been established. Sotatercept, an activin-signalling inhibitor, improved exercise capacity and haemodynamics in phase 2/3 PAH trials; however, patients with unrepaired CHD, including Eisenmenger syndrome, were excluded. The efficacy and safety of sotatercept in this population remain unknown.
Methods and analysis The SuMILE trial is a prospective, exploratory, multicentre, open-label, randomised, controlled trial conducted at 11 Japanese tertiary centres. 36 adults with vasodilator-resistant PAH due to unrepaired ASD, VSD or PDA, including Eisenmenger syndrome, will be randomised 2:1 to sotatercept add-on therapy plus vasodilator-based PAH therapy versus vasodilator-based PAH therapy alone. Sotatercept will be administered subcutaneously every 3 weeks in accordance with label-approved dose-modification rules for haemoglobin and platelet changes. The primary endpoint is the change in 6-min walk distance from baseline to week 24. Key clinical events will be independently adjudicated. Secondary endpoints include all-cause mortality or lung transplantation; pulmonary hypertension-related hospitalisation or initiation of parenteral prostacyclin and changes in WHO functional class, N-terminal pro-brain natriuretic peptide and emPHasis-10. Exploratory endpoints include genotype, right heart catheterisation and cardiac MRI parameters. The primary analysis will use ANCOVA, adjusting for baseline 6-min walk distance and randomisation stratum in the intention-to-treat population.
Ethics and dissemination The protocol has been reviewed and approved by the certified central review board (Kyushu University Hospital Clinical Ethics Review Board) and participating institutions. Written informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed journals, scientific conferences and trial registries.

kn-title=Surface Plasmon Resonances in Silver Nanodendrites : Trunk Length and Branch Connectivity Dependence en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study systematically investigates how trunk length and branch connectivity govern surface plasmon resonances in silver nanodendrites in the infrared (IR) region using a computational modeling strategy. We show that a continuous conductive trunk is essential for exciting long-wavelength collective plasmon modes. In a simulated bottom-up construction scheme, the trunk length is gradually increased to conductively connect additional branches to the backbone. Our results reveal that the fundamental δ mode resonance can be deterministically tuned across the mid-infrared spectrum (from 3840 nm to 4360 nm) primarily by controlling the trunk connectivity. As the number of connected branches grows, the lowest-order collective resonance peak exhibits a systematic redshift, and its resonance wavelength scales linearly with the effective dipole length Leff of the electron oscillation path. Concurrently, new higher-order modes emerge as local resonances of the connected substructures. These observations indicate that interrupting the conductive pathway causes a global collective mode to decompose into multiple resonances associated with more weakly coupled subsystems. The established linear scaling relationship provides a highly predictable design rule for this “programmable” connectivity, offering a robust platform for advanced applications such as multi-spectral infrared imaging, selective chemical sensing, and surface-enhanced infrared absorption (SEIRA) spectroscopy, where precise, a priori control over narrow-band infrared resonances is essential. en-copyright= kn-copyright= en-aut-name=MaQingyuan en-aut-sei=Ma en-aut-mei=Qingyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KishidaYuki en-aut-sei=Kishida en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeyasuNobuyuki en-aut-sei=Takeyasu en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShojiSatoru en-aut-sei=Shoji en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Informatics and Engineering, The University of Electro-communications kn-affil= affil-num=2 en-affil=Graduate School of Informatics and Engineering, The University of Electro-communications kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Informatics and Engineering, The University of Electro-communications kn-affil= en-keyword=Silver nanodendrites kn-keyword=Silver nanodendrites en-keyword=Surface plasmon resonances kn-keyword=Surface plasmon resonances en-keyword=Conductive coupling kn-keyword=Conductive coupling en-keyword=Topological connectivity kn-keyword=Topological connectivity en-keyword=Infrared nanoantennas kn-keyword=Infrared nanoantennas en-keyword=Plasmonic metamaterials kn-keyword=Plasmonic metamaterials END start-ver=1.4 cd-journal=joma no-vol=209 cd-vols= no-issue= article-no= start-page=117914 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=PPy-coated wire actuators for micromechanostimulation of cells – identification of immediate-early responsive mechanoregulatory genes in osteoblasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mechanotransduction, i.e., the conversion of mechanical cues into biochemical signals, is essential for bone development, remodeling, and adaptation. Although mechanical loading is known to regulate osteoblast function and bone homeostasis, dissecting the early and sustained mechanotransductive responses at the microscale remains challenging due to limitations of existing in vitro models. Here, we report the development and application of a mechanostimulation system comprising a polypyrrole (PPy)-based wire actuator that expands and contracts (4 μm in radius) upon electrical actuation and enables precise, localized micromechanical stimulation of a small number of cells within standard culture formats. Using this system, we applied short-term (30 min) cyclic (Cyc30) or static (Stat30), as well as prolonged (120 min) cyclic (Cyc120) stimulations to two osteoblast-like cells (MC3T3-E1 or KUSA-A1). Subsequent transcriptomic profiling and computational network analyses revealed that Cyc30 was not capable of inducing significant changes in mRNA expression, suggesting cellular adaptation to short-term cyclic loading. In contrast, Stat30 induced the upregulation of Fos, Btg2, Egr1, and Fosl1, all known genes associated with mechanotransduction, supporting the validity and reproducibility of our experimental mechanostimulation system. Notably, two long non-coding RNAs (B930036N10Rik and 5430431A17Rik) were identified for the first time as being upregulated in response to Stat30 stimuli. Among the differentially expressed genes (DEGs) upregulated by Cyc120 stimuli, Hmox1, a stress-inducible enzyme known for its roles in maintaining cellular homeostasis and promoting survival, was the only DEG repeatedly observed across the Cyc30/Cyc120 and Stat30/Cyc120 comparisons in both cell types, potentially emerging as a key stress-response gene under prolonged mechanical loading. Collectively, these results establish the PPy-based microactuator as a powerful tool for microscale mechanobiology, and provide molecular insight into immediate-early responsive transcriptional programs underlying osteoblastic mechanoadaptation conserved across different cell types. en-copyright= kn-copyright= en-aut-name=ChenJiamin en-aut-sei=Chen en-aut-mei=Jiamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Ortega-SantosAmaia B. en-aut-sei=Ortega-Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MartinezJose G. en-aut-sei=Martinez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=JagerEdwin W.H. en-aut-sei=Jager en-aut-mei=Edwin W.H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Physics, Chemistry and Biology (IFM), Linköping University kn-affil= affil-num=3 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Physics, Chemistry and Biology (IFM), Linköping University kn-affil= affil-num=6 en-affil=Department of Advanced International and Information Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Physics, Chemistry and Biology (IFM), Linköping University kn-affil= affil-num=8 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Mechanotransduction kn-keyword=Mechanotransduction en-keyword=Mechanostimulation kn-keyword=Mechanostimulation en-keyword=Osteoblasts kn-keyword=Osteoblasts en-keyword=Polypyrrole kn-keyword=Polypyrrole END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of caffeine on life-history traits on the red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, addressing insect pest infestation effectively requires environmentally sound and sustainable pest control methods that minimize environmental pollution. Caffeine (1, 3, 7-trimethylxanthine), a plant-derived secondary metabolite, has insecticidal, hormonal and antifeedant properties, making it a promising and more sustainable alternative for pest management. In this study, the red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), a serious stored pest, was used to investigate the effects of different caffeine concentrations on life-history traits. We applied two delivery methods: 1) oral exposure through a caffeine–sucrose solution for adults, and 2) dietary incorporation of caffeine powder mixed with wheat flour and brewer’s yeast for adults and their larvae. To evaluate the effect of caffeine on life-history traits, adult longevity, pupation rate, larval period, pupal weight, adult body size and food consumption were examined. Results revealed higher caffeine concentrations (> 1%) significantly reduced longevity, delayed pupation, decreased pupal number, pupal weight and adult body size in both males and females. Lower caffeine concentration (0.01%) increased pupal number but resulted in lower offspring quality, such as smaller pupal weight and adult size. The results show that caffeine has negative effects on life-history traits of T. castaneum, suggesting its potential use as a natural pesticide in caffeine-based sustainable pest-management programs and integrated pest management (IPM). en-copyright= kn-copyright= en-aut-name=NaingShine Shane en-aut-sei=Naing en-aut-mei=Shine Shane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa 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=Okayama University (Graduate School of Environmental, Life, Natural Science and Technology) kn-affil= affil-num=2 en-affil=Okayama University (Graduate School of Environmental, Life, Natural Science and Technology) kn-affil= affil-num=3 en-affil=Okayama University (Graduate School of Environmental, Life, Natural Science and Technology) kn-affil= en-keyword=Insect growth kn-keyword=Insect growth en-keyword=Life-history trait kn-keyword=Life-history trait en-keyword=Longevity kn-keyword=Longevity en-keyword=Pupal weight kn-keyword=Pupal weight en-keyword=Body size kn-keyword=Body size END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=3621 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Outcomes of Endoscopic Ultrasound-Guided Gallbladder Drainage for Acute Cholecystitis in Non-Surgical Candidates: A Multicenter Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is a minimally invasive alternative for managing acute cholecystitis in patients who are unsuitable for surgery. Although its short-term efficacy is well-established, its long-term outcomes, especially in patients with malignancy-associated cholecystitis, remain unclear. Methods: This multicenter, retrospective study included 139 patients who underwent EUS-GBD with a plastic stent for inoperable acute cholecystitis between January 2010 and October 2023. Patients were divided into two groups: a malignant group (n = 60) with cystic duct obstruction caused by cancer invasion or self-expandable metal stents, and a benign group (n = 79) with calculous or acalculous cholecystitis. The outcomes assessed included cholecystitis recurrence, time to recurrence, adverse events, and risk factors for recurrence. Results: Technical success was achieved in all patients, with an overall clinical success rate of 94.6%. Cholecystitis recurred significantly more frequently in the malignant group than in the benign group (13.3% vs. 2.5%; p = 0.015). Univariate analysis identified malignancy as a significant risk factor of recurrence (odds ratio, 5.92; p = 0.028). Conclusions: EUS-GBD is a safe and effective long-term treatment for cholecystitis in non-surgical candidates. However, malignancy-associated cholecystitis carries a high risk of recurrence, warranting careful follow-up and individualized management. en-copyright= kn-copyright= en-aut-name=HaradaKei en-aut-sei=Harada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkimotoYutaka en-aut-sei=Akimoto en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HattoriNao en-aut-sei=Hattori en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=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 Endoscopy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, National Organization Iwakuni Clinical Center kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Endoscopy, Okayama University Hospital, 2-5-1 Shikata-cho, Okayama 700-8558, Japan kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Endoscopy, Okayama University Hospital, 2-5-1 Shikata-cho, Okayama 700-8558, Japan kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=16 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=cholecystitis kn-keyword=cholecystitis en-keyword=drainage kn-keyword=drainage en-keyword=endosonography kn-keyword=endosonography en-keyword=gallbladder kn-keyword=gallbladder END start-ver=1.4 cd-journal=joma no-vol=367 cd-vols= no-issue= article-no= start-page=199724 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=Mycoviruses diversity in the black kōji mold, Aspergillus luchuensis (section Nigri) isolated from liquor-production environments in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Some fungal species in the genus Aspergillus are economically important due to their role in the production of liquors and various foods; however, their viromes, which may affect their performance, remain unexplored. Therefore, this study examined the viromes of nine strains of Aspergillus luchuensis (section Nigri), the black kōji mold used in the production of shochu (a traditional Japanese liquor) in Japan. It identified virus-like sequences related to alterna-, partiti-, curvula, botourmia-, narna-like, and umbra-like viruses. Some sequences appear to represent new variants (e.g., alterna- and gammapartitiviruses), while many others correspond to novel viral species within established or proposed mycoviral families. All A. luchuensis strains harbored multiple virus infections, with 2 to 7 viruses per strain. Three alternavirus strains with four-segmented double-stranded RNA (dsRNA) genomes were confirmed, along with minor variants co-present with the predominant strains. Notably, a gammapartitivirus appears to have two additional dsRNA genome segments, along with two satellite-like short dsRNA segments in some fungal isolates. Furthermore, at least five short RNAs (0.48–1.31 kb) were identified, three of which are possibly satellite-like RNAs associated with novel single-stranded RNA viruses (botourmia- and umbra-like viruses). These findings reveal the great diversity of mycoviruses in A. luchuensis populations and lay the foundation for further investigation into their impact on fungal phenotypes and liquor production. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NanajiMisaki en-aut-sei=Nanaji en-aut-mei=Misaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugaharaHitomi en-aut-sei=Sugahara en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FumihiroFujimori en-aut-sei=Fumihiro en-aut-mei=Fujimori 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=Graduate School of Tokyo Kasei University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Northwest A&F University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Tokyo Kasei University kn-affil= en-keyword=Aspergillus luchuensis kn-keyword=Aspergillus luchuensis en-keyword=Section Nigri kn-keyword=Section Nigri en-keyword=Mycovirus kn-keyword=Mycovirus en-keyword=RNA-seq kn-keyword=RNA-seq en-keyword=Virus population kn-keyword=Virus population en-keyword=Genome segment kn-keyword=Genome segment en-keyword=Fermentation kn-keyword=Fermentation en-keyword=Island kn-keyword=Island END start-ver=1.4 cd-journal=joma no-vol=185 cd-vols= no-issue=6 article-no= start-page=391 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260513 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Drug-induced sarcoidosis-like reaction following IL-4/IL-13 receptor blockade by dupilumab en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of the study is to review reported cases of dupilumab-associated drug-induced sarcoidosis-like reaction (DISR) and consider possible immunologic mechanisms. This short review aims to raise awareness of dupilumab-associated DISR and discuss safety considerations in pediatric patients.
Conclusion: Dupilumab is a human monoclonal antibody that reduces inflammation driven by T helper 2 (Th2) cells and is used to treat type 2 inflammatory disorders, including atopic dermatitis. The most common adverse reactions during the first year of treatment are local reactions at the injection site, conjunctivitis, and headache. Although DISR is rare, it has been documented in dupilumab-treated patients. We hypothesized that dupilumab shifts the Th1/Th2 equilibrium toward Th1 and granulomatous inflammation, which may present as DISR. We identified and reviewed 10 recently reported DISR cases and observed that reported features of DISR—including uveitis, optic neuritis and meningoencephalitis, bilateral hilar lymphadenopathy, and histopathologically noncaseating granulomas—can mimic systemic sarcoidosis. Discontinuation of dupilumab resulted in favorable outcomes in most reported DISR cases; however, symptoms worsened in some cases and sequelae became a concern. Case reports of DISR have so far been limited to adults or adolescents, but awareness of potential adverse effects of dupilumab remains important in pediatric patients. en-copyright= kn-copyright= en-aut-name=YasuiKozo en-aut-sei=Yasui en-aut-mei=Kozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Okayama University Hospital Center for Innovative Clinical Medicine kn-affil= en-keyword=Dupilumab kn-keyword=Dupilumab en-keyword=Sarcoidosis kn-keyword=Sarcoidosis en-keyword=IL-4 kn-keyword=IL-4 en-keyword=IL-13 kn-keyword=IL-13 en-keyword=Th1-Th2 balance kn-keyword=Th1-Th2 balance END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative study of Ni–CeO2 catalysts prepared by impregnation and coprecipitation for CO2 methanation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explores how synthesis methods affect the structure and CO2 methanation performance of Ni–CeO2 catalysts prepared by coprecipitation and impregnation under identical conditions. Coprecipitation generated particles below 100 nm with uniform elemental distribution, together with large bulk-like particles exhibiting locally concentrated Ni species, attributed to differences in hydroxide solubility. Impregnation, by contrast, produced very large particles (> 500 nm) with smaller particles attached, while maintaining relatively homogeneous elemental distribution. Coprecipitated catalysts showed slightly higher surface area and oxygen vacancy concentration, resulting in higher apparent turnover frequencies (TOFapp) below 300 °C due to enhanced CO2 adsorption and high Ni site density. However, at temperatures above 350 °C, impregnated catalysts displayed higher CH4 selectivity and TOFapp, indicating reduced kinetic limitations and more efficient active-site utilization. These results provide insights for rational design of efficient CO2 methanation catalysts. en-copyright= kn-copyright= en-aut-name=FukudaNobuko en-aut-sei=Fukuda en-aut-mei=Nobuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImanoShuichi en-aut-sei=Imano en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaharaNozomi en-aut-sei=Nakahara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=687 cd-vols= no-issue= article-no= start-page=120087 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=Phase diagram of Fe-C-S ternary system under planetary core conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-pressure, high-temperature experiments were conducted to investigate melting relations and phase assemblages in the Fe-C-S ternary system at 5 and 15 GPa, covering a temperature range of 1300–1900 K, conditions directly relevant to the Moon’s and Mercury’s cores. At 1300 K, the system is primarily governed by Fe-S eutectic melting, exhibiting notable complexity in the carbon-rich and sulfur-poor regions. With increasing temperature, the phase diagram simplifies: at 5 GPa and 1700 K, the Fe-Fe₃C-FeS system features three regions (Fe+L, C + L, and L). Similar phase assemblages are observed at 15 GPa, with Fe7C3 and diamond replacing Fe3C and graphite, respectively. Extensive Fe+L, C + L, and L regions are observed at 1900 K.
For a Moon’s core composed of a Fe-C-S alloy, nearly pure Fe is the only viable inner core phase above 1700 K. Below this temperature, both Fe and Fe₃C are potential solid inner core phases, depending on carbon content; a two-phase solid inner core is also theoretically possible. The inferred compositions of the outer core suggest densities of 6200–7300 kg/m³, with tighter constraints for models featuring an Fe₃C core.
At Mercury-relevant pressures, either Fe or Fe₇C₃ may form the solid inner core, again depending on carbon content. If the inner core is nearly pure Fe, the liquid outer core density ranges from 7300 to 7900 kg/m³. In both scenarios, a “snow” regime is plausible, though with distinct settling times. The ternary phase diagram indicates that Mercury is likely to develop a structurally layered inner core during secular cooling.

Herein, we systematically investigate the biocompatible amphiphilic triblock copolymer poly(d,l-lactic acid)-block-poly(ethylene oxide)-block-poly(d,l-lactic acid)(PLA-b-PEO-b-PLA) as a rheology modifier in toluene-in-water model emulsions. Owing to the selective adsorption of PLA end blocks at the oil–water interface and the solvation of the PEO midblock in the aqueous phase, this polymer is expected to form reversible droplet-bridging networks. During the process, the polymer concentration, molecular weight of the mid and end blocks, and the dispersed phase volume fraction were adjusted, and the factors governing network formation were elucidated using oscillatory rheology and stress-relaxation measurements. The results show that anchoring of the PLA end blocks and PEO-mediated bridging predominantly control the strength and dynamic reversibility of the network. Step-strain experiments further reveal that the droplet-bridging interactions can be disrupted under large deformation and partially recover when small-strain conditions are restored, confirming the presence of reversible physical associations. These findings establish a molecular design strategy for biodegradable telechelic copolymers as effective and reprocessable structuring agents in emulsion gels. The shear-responsive, tunable, and reversible nature of the droplet-bridging network makes this material platform particularly suitable for injectable emulsion gels for advanced soft matter and biomedical engineering applications. en-copyright= kn-copyright= en-aut-name=NakayamaHinako en-aut-sei=Nakayama en-aut-mei=Hinako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoAtsushi en-aut-sei=Matsumoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IidaYuya en-aut-sei=Iida en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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 and Biotechnology, Graduate School of Engineering, University of Fukui kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= en-keyword=PLA-b-PEO-b-PLA kn-keyword=PLA-b-PEO-b-PLA en-keyword=telechelic polymer kn-keyword=telechelic polymer en-keyword=rheology kn-keyword=rheology en-keyword=emulsion gel kn-keyword=emulsion gel en-keyword=viscoelasticity kn-keyword=viscoelasticity END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=9 article-no= start-page=e2025GL121619 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Apollo 17 Lunar Surface Gravimeter as a Seismometer: Relocating Shallow‐Moonquake Sources and Implications for Source Mechanism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Among the reported seismic events on the Moon, shallow moonquakes are known for their unique features, such as high-frequency energy excitation, similarity to intraplate earthquakes, and the largest energy release of all reported moonquakes. Despite these interesting features, a small number of samples (<80 events) and sparse seismic network observations prevented us from gaining an in-depth understanding of shallow moonquakes. In this study, by using the Apollo 17 gravimeter as a pseudo-seismometer, we extend the Apollo lunar seismic network and located a few shallow moonquakes more accurately. In addition, comparing the located shallow-moonquake epicenters with surface/subsurface geological features indicates that at least one event may be better explained by deep-seated faults within the crust. Along with a previous demonstration of low-frequency moonquakes, our analysis of high-frequency events shows that the Apollo 17 gravimeter can serve as a seismometer over a broader frequency range than previously considered. en-copyright= kn-copyright= en-aut-name=OnoderaKeisuke en-aut-sei=Onodera en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraTaichi en-aut-sei=Kawamura en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institut de Physique du Globe de Paris, Université Paris Cité kn-affil= en-keyword=Moon kn-keyword=Moon en-keyword=lunar seismology kn-keyword=lunar seismology en-keyword=tectonism kn-keyword=tectonism en-keyword=moonquake kn-keyword=moonquake END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue= article-no= start-page=16255 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260422 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Utility of SARS-CoV-2 Antibody Titers in the Management of Patients With Long COVID Infected With the Omicron Variant en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Long COVID (LC) presents persistent symptoms that pose a major clinical challenge. Identification of reliable biomarkers to evaluate LC pathophysiology is needed.
Objectives: To investigate whether serum S- and N-antibody titers against SARS-CoV-2 spike and nucleocapsid proteins reflect the clinical features of LC.
Methods: This retrospective observational study included patients diagnosed with Omicron variant-related LC who attended a post-COVID-19 outpatient clinic between July 2023 and November 2024 and provided informed consent for antibody testing.
Results: Among 275 patients (129 men and 146 women), 57 (21%) were unvaccinated. Median S- and N-antibody titers in vaccinated versus unvaccinated patients were 20,963 U/mL and 24.8 cut-off index (COI) versus 24 U/mL and 44.5 COI, respectively. S-antibody titers were associated with the number of vaccine doses received, whereas N-antibody titers correlated with disease severity during the acute phase of COVID-19 infection, with females having higher titers by multivariable analysis. N-antibody titers in unvaccinated patients with LC were negatively correlated with time interval from infection to clinic visit, with an estimated daily decline of 0.34% in measured N-antibody levels. Patients with LC having memory impairment had low S-antibody titers by multivariable logistic regression analysis, and low S-antibody levels were associated with reduced quality of life (QOL). Additionally, N-antibody titers positively correlated with lymphocyte counts and immunoglobulin levels.
Conclusion: Serum N-antibody titers reflect immune responses to COVID-19, although they are affected by gender differences and interval between infection and evaluation. Lower S-antibody titers were associated with brain fog symptoms and reduced QOL in patients with LC. en-copyright= kn-copyright= en-aut-name=KawaguchiMarina en-aut-sei=Kawaguchi en-aut-mei=Marina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsukiNobuyoshi en-aut-sei=Matsuki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FurukawaMasanori en-aut-sei=Furukawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HigashikageAkihito en-aut-sei=Higashikage en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=brain fog kn-keyword=brain fog en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=long COVID kn-keyword=long COVID en-keyword=Omicron variants kn-keyword=Omicron variants en-keyword=SARS-CoV-2 antibodies kn-keyword=SARS-CoV-2 antibodies END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e23328 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260418 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials en-subtitle= kn-subtitle= en-abstract= kn-abstract=With unique optical and physicochemical properties, carbon nanomaterials (CNMs), including carbon nanotubes, graphene-related materials, nanodiamonds, and carbon dots, are extensively explored as platforms for cancer diagnosis and treatment. However, in biofluids, CNMs spontaneously adsorb biomolecules to form an unpredictable corona, obstructing the implementation of their designed functions. In this review, we summarize how the intrinsic and acquired properties of CNMs affect protein corona formation, and the consequent biological and toxicological outcomes, as well as strategies to reshape the composition and structural organization of adsorbed proteins. This comprehensive knowledge will provide insights into developing CNMs with tailored corona and requested functions in cancer nanomedicine, advancing their translations into clinics. en-copyright= kn-copyright= en-aut-name=ZouYajuan en-aut-sei=Zou en-aut-mei=Yajuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HuYalei en-aut-sei=Hu en-aut-mei=Yalei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuJie en-aut-sei=Yu en-aut-mei=Jie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KomatsuNaoki en-aut-sei=Komatsu en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=CNRS, Immunology Immunopathology and Therapeutic Chemistry University of Strasbourg ISIS kn-affil= affil-num=3 en-affil=Graduate School of Human and Environmental Studies, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Human and Environmental Studies, Kyoto University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=carbondots kn-keyword=carbondots en-keyword=carbonnanotubes kn-keyword=carbonnanotubes en-keyword=graphene kn-keyword=graphene en-keyword=nanodiamonds kn-keyword=nanodiamonds en-keyword=proteins kn-keyword=proteins 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=20260506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feasibility of Comprehensive Genomic Profiling for Biliary Tract Cancer Using Transpapillary Biopsy Samples: A Prospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Patients with biliary tract cancer (BTC) often have actionable mutations, and comprehensive genomic profiling (CGP) plays an important role. However, the feasibility of CGP using transpapillary biopsy (TPB) samples remains unclear.
Methods: Thirty patients with suspected BTC based on radiographic imaging were enrolled. Pre-analytical criteria for CGP suitability were based on the OncoGuide NCC Oncopanel System (NCCOP) and FoundationOne CDx (F1CDx). Each patient underwent six biopsies using an endoscopic introducer: five biopsy samples were preserved as formalin-fixed paraffin-embedded (FFPE) samples and one as a fresh frozen (FF) sample. DNA quality indicators were compared between the two groups.
Results: Malignancy was confirmed in 29 patients, and one had a benign biliary stricture. Suitability rate was 31% (9/29) for NCCOP and 3.4% (1/29) for F1CDx. Compared to FFPE samples, FF samples demonstrated significantly higher DNA concentration [ng/μL, interquartile range (IQR)], [0.34 (0.16–0.95) vs. 37.8 (11.6–67.6), p < 0.001] and DNA integrity number (IQR) [7.1 (6.8–7.3) vs. 8.9 (8.3–9), p = 0.021].
Conclusions: Introducer-assisted multipass TPB may increase the rate of obtaining adequate CGP specimens, but its suitability remains limited and strongly panel dependent. Since FF samples have better DNA quality, establishing a system detailing their use is desirable.

Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene granitoids in Southwest Japan. Zircon U–Pb ages define two discrete magmatic episodes at 110–60 Ma and 45–30 Ma, separated by a magmatic hiatus of ∼10–15 Myr. These granitoid groups exhibit distinct isotopic signatures, indicating derivation from isotopically distinct magma sources linked to the paleo-Pacific (Izanagi) plate and the Philippine Sea plate, respectively. Isotope-based mass-balance modeling indicates higher sediment contributions to the older granitoids, with decreasing sediment input both landward and through time. The magmatic lull at ca. 52–40 Ma coincides with an abrupt isotopic shift and is interpreted to reflect plate reorganization, during which subduction of the paleo-Pacific plate was replaced by a transform or highly oblique plate boundary associated with the northward migration of the proto–Philippine Sea plate. Independent constraints from convergence rates, sediment flux, and accretionary complex development support this interpretation. These results demonstrate that granitoid magmatism in Southwest Japan was fundamentally controlled by temporal changes in subducted lithosphere and sediment flux driven by plate reorganization, highlighting the sensitivity of arc magmatism to transient tectonic regimes. en-copyright= kn-copyright= en-aut-name=DaoNghiem V. en-aut-sei=Dao en-aut-mei=Nghiem V. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YemerTsegereda A. en-aut-sei=Yemer en-aut-mei=Tsegereda A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MwaisubaTulibako T. en-aut-sei=Mwaisuba en-aut-mei=Tulibako T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaguchiChie en-aut-sei=Sakaguchi en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitagawaHiroshi en-aut-sei=Kitagawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiKatsura en-aut-sei=Kobayashi en-aut-mei=Katsura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ImaokaTeruyoshi en-aut-sei=Imaoka en-aut-mei=Teruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraEizo en-aut-sei=Nakamura en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=3 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=4 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=5 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=6 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= affil-num=7 en-affil=Division of Earth Science, Graduate School of Sciences and Technology for Innovation, Yamaguchi University kn-affil= affil-num=8 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University at Misasa kn-affil= en-keyword=granitoids kn-keyword=granitoids en-keyword=Pb–Sr–Nd–Hf isotopes kn-keyword=Pb–Sr–Nd–Hf isotopes en-keyword=Pacific-Philippine Sea plates kn-keyword=Pacific-Philippine Sea plates en-keyword=sub-crustal origin kn-keyword=sub-crustal origin en-keyword=tectonic transition kn-keyword=tectonic transition END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=4 article-no= start-page=e70187 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Type III CD38 is present in the membrane of neurosecretory vesicles and has a cytosol-facing catalytic domain in primate oxytocin neurons en-subtitle= kn-subtitle= en-abstract= kn-abstract=CD38, an ADP-ribosyl cyclase that generates cyclic ADP-ribose (cADPR), is essential for Ca2+-dependent oxytocin release. However, its subcellular localisation and membrane topology within oxytocin neurones have remained unclear. We investigated the distribution and orientation of CD38 in oxytocin-producing neurones of Japanese macaques (Macaca fuscata) using immunoelectron microscopy combined with biochemical isolation of neurosecretory vesicles (NSVs). CD38 immunoreactivity was selectively detected on oxytocin-containing NSVs in axon terminals in the posterior pituitary and dendrites of the supraoptic nucleus, whereas vasopressin vesicles and the plasma membrane lacked detectable labelling. Cryo-electron microscopy confirmed the structural integrity of purified NSV fractions, and Western blotting verified the presence of CD38 protein within these fractions. Permeabilisation-dependent immunogold labelling further demonstrated that the NSV membrane localisation of CD38 and that the N-terminal region of CD38 is oriented toward the vesicle lumen, consistent with a type III membrane topology in which the catalytic domain faces the cytosol. This arrangement positions the active site near cytosolic NAD+, enabling localised cADPR production adjacent to Ca2+-mobilising channels that support regulated exocytosis. These findings identify, in primate oxytocin neurones, a previously unrecognised, vesicle-associated pool of CD38 with a cytosol-facing catalytic domain and provide a structural framework for understanding how intracellular type III CD38 contributes to neuropeptide release. en-copyright= kn-copyright= en-aut-name=MiyamotoTatsuki en-aut-sei=Miyamoto en-aut-mei=Tatsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsushimaAkari en-aut-sei=Matsushima en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtuboAkito en-aut-sei=Otubo en-aut-mei=Akito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SongChihong en-aut-sei=Song en-aut-mei=Chihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurataKazuyoshi en-aut-sei=Murata en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtiTakumi en-aut-sei=Oti en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Biology, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Exploratory Research Center on Life and Living Systems (ExCELLS), National Institutes of Natural Sciences kn-affil= affil-num=5 en-affil=Exploratory Research Center on Life and Living Systems (ExCELLS), National Institutes of Natural Sciences kn-affil= affil-num=6 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=CD38 kn-keyword=CD38 en-keyword=cyclic ADP-ribose kn-keyword=cyclic ADP-ribose en-keyword=membrane topology kn-keyword=membrane topology en-keyword=neurosecretory vesicles kn-keyword=neurosecretory vesicles en-keyword=oxytocin kn-keyword=oxytocin END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=3 article-no= start-page=e70554 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Atypical Surgical Case of Lung Cancer With Unilateral Absence of the Pulmonary Artery, With Only the Superior Branch Remaining en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 69-year-old woman was referred to our department for an abnormal shadow on chest radiography. Contrast-enhanced computed tomography (CT) revealed a solid nodule in the right lower lobe and defects in the branches of the middle and lower lobes of the pulmonary artery (PA). Furthermore, collateral circulation had developed via the right internal thoracic, bronchial, intercostal, inferior phrenic, and subdiaphragmatic arteries. The solid nodule was diagnosed as adenocarcinoma by CT-guided biopsy. The day before surgery, embolization was performed using interventional radiology (IVR) to mitigate the risk of bleeding during thoracotomy, resulting in minimal intraoperative bleeding during the subsequent right middle and lower lobectomies with lymph node dissection (ND2a-1). UAPA is a rare congenital abnormality characterized by unilateral pulmonary artery agenesis. The presence of recurrent infections, extensive intrathoracic adhesions, and developed collateral circulation may pose challenges during surgical procedures. en-copyright= kn-copyright= en-aut-name=OkadaKazuhiro en-aut-sei=Okada en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomiokaYasuaki en-aut-sei=Tomioka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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=8 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=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=interventional radiology kn-keyword=interventional radiology en-keyword=lung cancer kn-keyword=lung cancer en-keyword=unilateral absence of the pulmonary artery kn-keyword=unilateral absence of the pulmonary artery END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue= article-no= start-page=000016 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cryogenic buffer gas beam source with in situ ablation target replacement en-subtitle= kn-subtitle= en-abstract= kn-abstract=The design and performance of a cryogenic buffer gas beam source with a load-lock system is presented. The third generation of advanced cold molecule electric dipole moment search (ACME III) uses this source to produce a beam of cold, slow thorium monoxide (ThO) molecules. A feature of the apparatus is the capability of replacing the ablation targets without interrupting the vacuum or cryogenic conditions, thus increasing the average signal in the eEDM search. The beam source produces 1.3×1011 ground-state ThO molecules per pulse on average, with rotational temperature of 4.8K, molecular beam solid angle of 0.31sr, and forward velocity of 200ms−1, parameters that are consistent with the performance of a traditional source (without a load lock) requiring time-consuming thermal cycles for target replacement. Long-term yield improvement of ∼40% is achieved when the load-lock system is employed to replace targets every two weeks. en-copyright= kn-copyright= en-aut-name=HanZhen en-aut-sei=Han en-aut-mei=Zhen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LasnerZack en-aut-sei=Lasner en-aut-mei=Zack kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DiverCollin en-aut-sei=Diver en-aut-mei=Collin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HuPeiran en-aut-sei=Hu en-aut-mei=Peiran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=WuXing en-aut-sei=Wu en-aut-mei=Xing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WattsMaya en-aut-sei=Watts en-aut-mei=Maya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=YoshimuraKoji en-aut-sei=Yoshimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FanXing en-aut-sei=Fan en-aut-mei=Xing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=GabrielseGerald en-aut-sei=Gabrielse en-aut-mei=Gerald kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DoyleJohn M. en-aut-sei=Doyle en-aut-mei=John M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=DeMilleDavid en-aut-sei=DeMille en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Physics, University of Chicago kn-affil= affil-num=2 en-affil=Department of Physics, Harvard University kn-affil= affil-num=3 en-affil=Center for Fundamental Physics, Northwestern University kn-affil= affil-num=4 en-affil=Department of Physics, University of Chicago kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Facility for Rare Isotope Beams, Michigan State University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Center for Fundamental Physics, Northwestern University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=11 en-affil=Department of Physics, Harvard University kn-affil= affil-num=12 en-affil=Center for Fundamental Physics, Northwestern University kn-affil= affil-num=13 en-affil=Department of Physics, Harvard University kn-affil= affil-num=14 en-affil=Department of Physics, University of Chicago 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=20260426 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Counterion condensation, ion pairing and scattering properties of carboxymethyl cellulose with mono- and di-valent ions en-subtitle= kn-subtitle= en-abstract= kn-abstract=We study the scattering and conductometric properties of a semiflexible polyelectrolyte, carboxymethyl cellulose (CMC), with monovalent and divalent counterions in aqueous media without added salts. The scattering patterns for the magnesium salts of CMC display a broad shoulder instead of the scattering peak observed for the monovalent salts. This suggests weaker electrostatic repulsion between chains and a consequent loss of local order. The result is consistent with conductivity measurements, which reveal that the effective charge of the backbone for MgCMC is approximately half that of NaCMC. The decrease in charge density agrees with Oosawa–Manning condensation, which expects the charge density to be inversely proportional to the counterion valence. Alkali metal counterions show large differences in ion-pair formation but only a weak effect in counterion condensation. We suggest that paired ions are a subset of condensed ions. A review of different methods to evaluate counterion condensation, including potentiometry, osmometry and viscosity-based methods is presented. Qualitative agreement between these methods is found and possible reasons for the discrepancies are discussed. en-copyright= kn-copyright= en-aut-name=GharehTapehElmira Abbasi en-aut-sei=GharehTapeh en-aut-mei=Elmira Abbasi 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=HorkayFerenc en-aut-sei=Horkay en-aut-mei=Ferenc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HouCan en-aut-sei=Hou en-aut-mei=Can kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LopezCarlos G. en-aut-sei=Lopez en-aut-mei=Carlos G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HohenschutzMax en-aut-sei=Hohenschutz en-aut-mei=Max kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Materials Science and Engineering Department, The Pennsylvania State 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=Section on Quantitative Imaging and Tissue Sciences, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health kn-affil= affil-num=4 en-affil=Institute of Physical Chemistry, RWTH Aachen University kn-affil= affil-num=5 en-affil=Materials Science and Engineering Department, The Pennsylvania State University kn-affil= affil-num=6 en-affil=Institute of Physical Chemistry, RWTH Aachen University kn-affil= en-keyword=Polyelectrolyte kn-keyword=Polyelectrolyte en-keyword=Counterion condensation kn-keyword=Counterion condensation en-keyword=Carboxymethyl cellulose kn-keyword=Carboxymethyl cellulose en-keyword=SAXS kn-keyword=SAXS en-keyword=Conductivity kn-keyword=Conductivity en-keyword=Ion pairing kn-keyword=Ion pairing END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue=1 article-no= start-page=28 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 79th Annual Meeting of the Chugoku-Shikoku Branch of the Japanese Association of Anatomists kn-title=日本解剖学会第79回中国・四国支部学術集会 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name=大内淑代 kn-aut-sei=大内 kn-aut-mei=淑代 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 細胞組織学 END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue=1 article-no= start-page=26 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 46th Annual Meeting of the Japan Society for the Study of Obesity and The 43rd Annual Meeting of the Japanese Society for Treatment of Obesity kn-title=第46回日本肥満学会・第43回日本肥満症治療学会学術集会 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name=和田淳 kn-aut-sei=和田 kn-aut-mei=淳 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 腎・免疫・内分泌代謝内科学 END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue=1 article-no= start-page=23 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Future perspectives of genomic medicine in sick newborn infants kn-title=原因不明の重症新生児に対するゲノム解析の役割と展望 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TakenouchiToshiki en-aut-sei=Takenouchi en-aut-mei=Toshiki kn-aut-name=武内俊樹 kn-aut-sei=武内 kn-aut-mei=俊樹 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Pediatric Neurology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 小児発達病因病態学 END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue=1 article-no= start-page=19 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Drug interaction (65.

kn-subject= en-title= kn-title=Lateral Variations in Lunar Crustal Thickness Inferred From Apollo Seismic and GRAIL Gravity Data en-subtitle= kn-subtitle= en-abstract= kn-abstract=The internal structure of the Moon is key to understanding its formation, evolution, and bulk composition. In particular, determining the structure of the crust–mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to fully constrain it. To address this, we used seismic wave arrivals from impact events, which yield constraints on the crust at both the impact sites and the Apollo stations, to invert for local crustal thickness. Based on a series of assumed crust and mantle density models, we compared Moho depths inferred from global gravity recovery and interior laboratory gravity data with those from seismic observations. Although the gravity‐derived results broadly capture the overall Moho relief, local discrepancies remain, with differences reaching up to 10 km in the vicinity of the Apollo 17 Saturn IVB impact site. These results may reflect regional geological anomalies and highlight the importance of incorporating multiple seismically constrained crustal thickness estimates as anchors in gravity inversions. Using seven seismic anchor points and assuming an upper mantle velocity of Vp = 7.68 km/ s, an upper mantle density of 3,280 kg/m3, and a crustal density of 2,693 kg/m3, we obtain an average lunar crustal thickness of 43.6 ± 1.9 km. The findings also provide valuable guidance for future global 3D modeling of the Moon. en-copyright= kn-copyright= en-aut-name=ZhangXiang en-aut-sei=Zhang en-aut-mei=Xiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraTaichi en-aut-sei=Kawamura en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DrilleauMélanie en-aut-sei=Drilleau en-aut-mei=Mélanie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LognonnéPhilippe en-aut-sei=Lognonné en-aut-mei=Philippe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HenriSamuel en-aut-sei=Henri en-aut-mei=Samuel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=XuZongbo en-aut-sei=Xu en-aut-mei=Zongbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OnoderaKeisuke en-aut-sei=Onodera en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BodinThomas en-aut-sei=Bodin en-aut-mei=Thomas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Université Paris Cité, Institut de physique du globe de Paris, CNRS kn-affil= affil-num=2 en-affil=Université Paris Cité, Institut de physique du globe de Paris, CNRS kn-affil= affil-num=3 en-affil=Université Paris Cité, Institut de physique du globe de Paris, CNRS kn-affil= affil-num=4 en-affil=Université Paris Cité, Institut de physique du globe de Paris, CNRS kn-affil= affil-num=5 en-affil=Université Paris Cité, Institut de physique du globe de Paris, CNRS kn-affil= affil-num=6 en-affil=Université Paris Cité, Institut de physique du globe de Paris, CNRS kn-affil= affil-num=7 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=8 en-affil=Instituto de Ciencias del Mar (ICM)–CSIC 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=20260429 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CDPKs as Ca2+ signaling decoders in guard cell signaling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Stomatal movements are essential for balancing photosynthetic carbon dioxide uptake with water conservation and defense against pathogens. These processes are controlled by complex signaling networks in guard cells, in which calcium ions (Ca2+) act as a ubiquitous second messenger. Although stimulus-specific Ca2+ signatures have been well documented, how these signals are decoded into distinct physiological responses remains a central question in plant biology. Increasing evidence highlights calcium-dependent protein kinases (CDPKs) as key signal decoders in guard cell signaling. This mini-review summarizes recent advances in our understanding of how CDPKs perceive and translate Ca2+ fluctuations into stomatal responses. We focus on the roles of CDPKs in signaling pathways triggered by diverse stimuli, including phytohormones such as abscisic acid ABA, jasmonates, and salicylic acid, as well as biotic cues such as microbe- or pathogen-associated molecular patterns (MAMPs/PAMPs) and pathogen infection. We also discuss how gaseous signals and metabolic cues are integrated into CDPK-mediated pathways. In addition to their established role as downstream decoders of Ca2+ signals, emerging studies suggest that CDPKs can act upstream of Ca2+ oscillations and may also function through Ca2+-independent mechanisms. Together, these findings highlight the context-dependent and integrative roles of CDPKs in regulating stomatal behavior, contributing to plant fitness under fluctuating environmental conditions. en-copyright= kn-copyright= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Ca2+ signaling kn-keyword=Ca2+ signaling en-keyword=CDPK kn-keyword=CDPK en-keyword=Signal decoding kn-keyword=Signal decoding en-keyword=Stomata kn-keyword=Stomata END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=3 article-no= start-page=e70500 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early sedation intensity and psychological outcomes in critically ill adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Long-term psychological impairment is a major concern for intensive care unit (ICU) survivors. Early deep sedation during mechanical ventilation has been associated with poor short-term outcomes and mortality after ICU discharge; however, its relationship with psychological outcomes remains unclear.
Aim: To investigate sedation intensity during the first 24 h of mechanical ventilation and its association with psychological impairment 3 months after ICU discharge.
Study Design: This retrospective ancillary analysis of a single-centre cohort study was conducted in two general ICUs at a university hospital in Japan. Eligible patients stayed in the ICU for more than 48 h and received mechanical ventilation for more than 8 h. Sedation intensity was quantified using the Sedation Index (SI) and Agitation Index (AI) derived from Richmond Agitation-Sedation Scale scores during the first 24 h. Psychological impairment 3 months post-ICU discharge was assessed based on symptoms of post-traumatic stress, anxiety and depression. Associations were examined using hierarchical logistic regression.
Results: Among 130 participants, the median age was 64 years, and the median ventilation duration was 14 h. The median SI was 3.0; 47% had SI > 3, and 8.5% had AI > 0. Sedation intensity showed no significant association with psychological impairment (SI: adjusted odds ratio [OR] 0.87, 90% confidence interval [CI] 0.57–1.33, p = 0.59; AI: adjusted OR 0.21, 90% CI 0.01–3.08, p = 0.34). However, any agitation during the ICU stay was associated with psychological outcomes (adjusted OR 2.61, 90% CI 1.16–5.88, p = 0.05).
Conclusions: This study did not identify a statistically significant association between early sedation intensity and psychological impairment 3 months after ICU discharge.
Relevance to Clinical Practice: Critical care nurses should carefully titrate sedation from the initiation of mechanical ventilation to avoid unnecessary deep sedation, considering sedation intensity over time, while actively assessing agitation and its underlying causes. en-copyright= kn-copyright= en-aut-name=IwataniMikiko en-aut-sei=Iwatani en-aut-mei=Mikiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University Hospital; Graduate School of Health Sciences, Doctoral Program, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=depression kn-keyword=depression en-keyword=post-intensive care syndrome kn-keyword=post-intensive care syndrome en-keyword=post-traumatic stress disorder kn-keyword=post-traumatic stress disorder en-keyword=sedation intensity kn-keyword=sedation intensity END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue= article-no= start-page=2026010 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=Supplementation of 5-Aminolevulinic Acid Suppressed Body Weight Loss and Reduced Disease Severity During Eimeria tenella Infection in Broiler Chickens en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the effects of 5-aminolevulinic acid (5-ALA) supplementation in broiler chickens infected with Eimeria tenella. To assess these effects, chickens supplemented with 20 ppm 5-ALA (5-ALA group) were compared with non-supplemented controls (control group). Sporulated E. tenella oocysts (2.0 × 103 oocysts per animal) were administered orally to 2-week-old broiler chickens. Body weight was measured weekly, and fecal samples were collected daily from 4 to 15 days post-infection (dpi). Fecal oocyst shedding was quantified using the sucrose flotation method. Cecal tissues were collected at 5 dpi for histopathological analysis and lesion scoring. The animals in the 5-ALA group exhibited significantly greater weight gain and milder clinical signs than those in the control group. Fecal oocyst shedding was highest at 7 dpi in both groups; however, the 5-ALA group exhibited significantly lower oocyst output than the control group. The total number of fecal oocysts shed during the acute infection period was significantly lower in the 5-ALA group than in the control group. Histopathological analysis revealed that although both groups exhibited epithelial hyperplasia and E. tenella schizonts in the cecal submucosa, inflammatory cell infiltration, cecal tissue damage, and histological lesion scores were significantly lower in the 5-ALA group than in the control group. These results suggest that 5-ALA supplementation may mitigate the clinical, parasitological, and histological effects of E. tenella infection in broiler chickens. en-copyright= kn-copyright= en-aut-name=HanifTaqi Ahmad en-aut-sei=Hanif en-aut-mei=Taqi Ahmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsubayashiMakoto en-aut-sei=Matsubayashi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Veterinary Science, Graduate School of Veterinary Sciences, Osaka Metropolitan University kn-affil= affil-num=3 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=5-aminolevulinic acid kn-keyword=5-aminolevulinic acid en-keyword=avian coccidiosis kn-keyword=avian coccidiosis en-keyword=broilers kn-keyword=broilers END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=265 end-page=271 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=Automatic Detection of Turning Over in Bed with Protection of Privacy Using Four Low-resolution Thermal Sensors to Support Nursing Care en-subtitle= kn-subtitle= en-abstract= kn-abstract=Turning over in bed, especially turning over at night, is a vital human unconscious behavior. Clinically, this movement disperses pressure between the body and bed, thus preventing bedsores. Several devices, such as acceleration and pressure sensors, can count turning overs automatically; however, they often require installation on the patients or in the bed. The simplest and noninvasive method to count turning overs is to record and count on video images, but this method cannot protect privacy. Images obtained using thermal sensors have been used to protect privacy; however, there are no reports of counting turning overs automatically using low-resolution sensors. We developed a novel device equipped with four low-resolution thermal sensors, with each sensor recording only an 8×8-pixel thermal image. The original data can protect patient privacy because the resolution is only ~28.8×28.8 cm per body, which is the lowest resolution compared to previous reports using thermal images. Using four sensors simultaneously enables us to collect sufficient data for automatic identification. We first used the bilinear interpolation method employed in a previous report to count turning overs; however, the results were unsatisfactory because turning overs produced extremely subtle changes in the original data compared with postural changes such as falls. After several attempts, we finally developed a unique identification program that interleaved all data from four sensors and then identified turning overs using residual neural network-18. Using the new system, the accuracy, recall, and precision of counting turning overs in bed improved to approximately 90% with an acceptable computation load in an experiment conducted on volunteers. This study demonstrated the feasibility of our device to count turning overs in clinical settings by the new identification program using four 8×8-pixel thermal images per frame, which have sufficiently low resolution to protect patient privacy. en-copyright= kn-copyright= en-aut-name=ChouJyun-Jhe en-aut-sei=Chou en-aut-mei=Jyun-Jhe 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=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=ShihChi-Sheng en-aut-sei=Shih en-aut-mei=Chi-Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Computer Science and Information Engineering, National Taiwan University kn-affil= affil-num=2 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Graduate Institute of Networking and Multimedia, National Taiwan University kn-affil= en-keyword=turning overs kn-keyword=turning overs en-keyword=privacy kn-keyword=privacy en-keyword=thermal sensors kn-keyword=thermal sensors en-keyword=low-resolution kn-keyword=low-resolution en-keyword=ResNet kn-keyword=ResNet END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=e71853 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multi-Transcriptomic Analysis Reveals That EREG-Driven TME Crosstalk Defines Anti-EGFR Response in Colorectal Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sidedness influences colorectal cancer (CRC) prognosis and treatment response, yet the mechanism dictating differential EGFR inhibitor (EGFRI) sensitivity is unclear. This study investigated the tumor microenvironment (TME) in relation to EGFRI eligibility―clinically defined by factors such as tumor sidedness (e.g., left-sided), RAS/BRAF wild-type status, and microsatellite stability (MSS)―using integrated single-cell RNA sequencing (scRNA-seq), with bulk RNA-seq and spatial transcriptomics validation. We found cancer cell features reflected EGFRI eligibility more strongly than sidedness. EGFRI eligible tumors exhibited high Epiregulin (EREG) expression by cancer cells. Cell interaction analysis revealed a specific “EREG/EGFR/CSF axis” in EGFRI eligible CRC: EREG derived from cancer cell stimulates EGFR-expressing non-myCAF subtypes of cancer-associated fibroblasts (CAFs), which signal via CSF to M1/M2-like Tumor-Associated Macrophages/Monocytes (TAM/TAMo), potentially promoting M2 polarization. Spatial analysis confirmed the proximity of these interacting cell populations and localized EGFR pathway activation near cancer cells specifically in eligible tumors. This study provides a TME-centric view of EGFRI eligibility, identifying a key intercellular communication network driving differential responses. These findings suggest TME features could offer more precise patient stratification than sidedness alone, potentially improving CRC therapeutic strategies. en-copyright= kn-copyright= en-aut-name=TaniguchiAtsuki en-aut-sei=Taniguchi en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogiShohei en-aut-sei=Nogi en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YagiTomohiko en-aut-sei=Yagi en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell–cell interaction kn-keyword=cell–cell interaction en-keyword=colorectal cancer kn-keyword=colorectal cancer en-keyword=EGFR inhibitor eligibility kn-keyword=EGFR inhibitor eligibility en-keyword=Epiregulin (EREG) kn-keyword=Epiregulin (EREG) en-keyword=tumor microenvironment kn-keyword=tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=2 article-no= start-page=175 end-page=180 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=General anesthesia management for oral surgery in a patient with plastic bronchitis associated with Fontan circulation: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plastic bronchitis is a rare condition in which mucus plugs obstruct the bronchi, potentially leading to fatal respiratory failure. It has been reported in some patients with congenital heart disease following Fontan surgery. We report the general anesthesia management of a 22-year-old female patient with Fontan circulation and type II plastic bronchitis that was controlled using regular intravenous heparin injections. In this case, concerns existed regarding airway obstruction by bronchial plugs and hemodynamic instability specific to the Fontan circulation. During endotracheal intubation, the absence of mucus plugs was confirmed using a flexible bronchoscope. Intraoperatively, ventilation was managed at low pressure to avoid an increase in intrathoracic pressure caused by high positive-pressure ventilation. Additionally, fluid overload was avoided to prevent elevations in the central venous pressure. Consequently, perioperative management can be safely performed without any respiratory or circulatory complications. As treatment outcomes improve, the number of dental and oral surgical procedures in adult patients with congenital heart disease is expected to increase. Therefore, knowledge of congenital heart disease and its sequelae, such as plastic bronchitis, is essential to perform appropriate risk assessment and management. en-copyright= kn-copyright= en-aut-name=NodaKaho en-aut-sei=Noda en-aut-mei=Kaho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiokaYukiko en-aut-sei=Nishioka en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiHitoshi en-aut-sei=Higuchi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashimotoFumika en-aut-sei=Hashimoto en-aut-mei=Fumika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeSaki en-aut-sei=Miyake en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Anesthesia, General kn-keyword=Anesthesia, General en-keyword=Plastic Bronchitis kn-keyword=Plastic Bronchitis en-keyword=Fontan Procedure kn-keyword=Fontan Procedure en-keyword=Oral Surgical Procedures kn-keyword=Oral Surgical Procedures END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=13650 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sex-related differences in blood concentrations and emergence profiles following total intravenous anesthesia with remimazolam and remifentanil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Remimazolam is a novel, short-acting benzodiazepine, which is characterized by rapid onset and quick recovery. The clinical efficacy and metabolism of many intravenous anesthetics are known to be influenced by sex; however, the effects of sex on the anesthetic efficacy and metabolism of remimazolam remain unclear. This prospective observational study examined sex-related differences in pharmacokinetics and emergence profiles after total intravenous anesthesia was induced with remimazolam and remifentanil in patients undergoing oral and maxillofacial surgery. Thirty-five American Society of Anesthesiologists Physical Status 1 adults (19 females, 16 males), aged 18–49 years, received standardized dosing based on their actual body weights. Serum remimazolam concentrations were measured at the end of administration and immediately before extubation using high-performance liquid chromatography. Although the emergence time did not differ significantly between the sexes, the mean emergence time of the females was approximately 80 s shorter. Serum remimazolam concentrations were significantly lower in females at both measurement time points (p < 0.001). This may suggest that remimazolam is metabolized more rapidly in women. Although these sex-related pharmacokinetic differences did not affect the time to awakening under combined remimazolam and remifentanil anesthesia, clinicians should be aware of potential sex differences in the pharmacokinetics of remimazolam. en-copyright= kn-copyright= en-aut-name=SatoRiko en-aut-sei=Sato en-aut-mei=Riko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiguchiHitoshi en-aut-sei=Higuchi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiokaYukiko en-aut-sei=Nishioka en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeSaki en-aut-sei=Miyake en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=10 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Compact potential sensor for spacecraft based on a silicon photonic waveguide en-subtitle= kn-subtitle= en-abstract= kn-abstract=Satellites charge up due to incoming electrons and ions, resulting in an electrical potential difference (ΔV) between the satellite and outer space. This can cause electrostatic discharge (ESD) events, damaging electronic devices. To reduce failures due to ESD, sensors monitoring the ΔV can be helpful. Due to spacecraft’s restrictions, the sensors should be as small as possible. While small potential sensors in terrestrial applications are often based on electrical conduction in semiconductors, such sensors are not suitable for space application due to a weak resistance to cosmic radiation and ESD. Here, we report a compact sensor based on another sensing method: the utilization of light absorption in a silicon photonic waveguide. We performed experiments in a vacuum chamber simulating the space plasma environment to demonstrate that the light attenuation in the waveguide depends on the ΔV. Our results further indicate that our sensor exhibits a high resistance to ESD. en-copyright= kn-copyright= en-aut-name=OtsukaKosei en-aut-sei=Otsuka en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahamaWataru en-aut-sei=Takahama en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HigashiguchiTakeki en-aut-sei=Higashiguchi en-aut-mei=Takeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikunagaKazuya en-aut-sei=Kikunaga en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Space Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=4 en-affil=Department of Physics and Electronics, Osaka Metropolitan University kn-affil= affil-num=5 en-affil=Sensing Technology Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=6 en-affil=Electrostatic Engineering DEPT, Kasuga Denki INC kn-affil= affil-num=7 en-affil=Department of Space Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=8 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=5 article-no= start-page=115667 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=Wnt3-mediated fibrosis and carcinogenesis of lung squamous cell carcinoma in idiopathic pulmonary fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Idiopathic pulmonary fibrosis (IPF) increases the risk of lung squamous cell carcinoma (LUSC), yet its molecular pathogenesis remains unclear. We conducted multi-omics analysis, including single-cell RNA sequencing and digital spatial profiling, on LUSC specimens from seven patients with usual interstitial pneumonia (UIP). In UIP lung tissue, metaplastic basal cells arising from the transdifferentiation of alveolar type 2 (AT2) cells were increased. LUSC tumors arising within UIP exhibited molecular profiles and trajectory dynamics suggesting derivation from these metaplastic basal cells. Both UIP-affected tissue and associated tumors showed activation of Wnt signaling, particularly WNT3 expression. Additionally, enrichment of the nuclear factor erythroid 2-related factor 2 (NRF2)-linked antioxidant response was observed in LUSC within UIP. Targeting Wnt/β-catenin signaling restored the sensitivity of these stress-adapted cancer cell lines to oxidative damage. These findings suggest that LUSC within UIP originates from AT2-derived metaplastic basal cells and involves aberrant Wnt3 activation, linking fibrosis to carcinogenesis and highlighting a potential therapeutic strategy. en-copyright= kn-copyright= en-aut-name=MatsuokaAtsushi en-aut-sei=Matsuoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=
