However, the mechanisms by which exercise influences psoriatic pathogenesis remain insufficiently understood. To investigate the effects of aerobic exercise on obesity-associated psoriasis, wild-type mice were fed a high-fat diet (HFD) for 7 weeks to induce obesity and subsequently underwent moderate-intensity treadmill running for 3 weeks. Psoriasiform dermatitis was induced by daily topical application of imiquimod (IMQ) to the skin for five consecutive days. HFD increased body weight, epididymal fat mass, and serum cholesterol. HFD-fed mice developed more severe IMQ-induced psoriatic skin changes compared with normal diet-fed mice. Treadmill exercise modestly reduced body weight gain and attenuated epidermal hyperplasia in HFD-fed mice. In contrast, inflammatory cytokine expression, including Tnfa, Il17a, and Il23a, showed modest increases in the skin of HFD-fed exercised mice, which did not parallel the improvement in epidermal hyperplasia. Overall, these findings indicate that while obesity exacerbates psoriasiform dermatitis, aerobic exercise ameliorates epidermal hyperplasia in obese mice without corresponding changes in inflammatory cytokine expression in the skin, suggesting that exercise may influence psoriatic skin changes through multiple metabolic and immunological pathways. en-copyright= kn-copyright= en-aut-name=MatsudaYoshihiro en-aut-sei=Matsuda en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakezakiDaiki en-aut-sei=Takezaki en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoYuma en-aut-sei=Sakamoto en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BabaNobuyasu en-aut-sei=Baba en-aut-mei=Nobuyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IsekiMasanori en-aut-sei=Iseki en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShiomiTatsushi en-aut-sei=Shiomi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MukaiTomoyuki en-aut-sei=Mukai en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= affil-num=9 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= en-keyword=psoriasis kn-keyword=psoriasis en-keyword=obesity kn-keyword=obesity en-keyword=aerobic exercise kn-keyword=aerobic exercise en-keyword=imiquimod kn-keyword=imiquimod en-keyword=high-fat diet kn-keyword=high-fat diet END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=7 article-no= start-page=810 end-page= 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=Effect of Universal Adhesives on Resin Cement?Fiber Post?Core Materials en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study evaluated eleven resin cements used as core build-up materials by examining the following properties: (a) push-out force between root dentin and the fiber post; (b) pull-out force between the fiber post and the core build-up material; (c) shear bond strength of the resin cement to root dentin; (d) flexural strength of the resin cement; and (e) flexural modulus of elasticity of the resin cement. The purpose of this investigation was to clarify the relationships between recently available universal adhesives, core build-up materials, resin cements, and fiber posts. All experiments were performed at two evaluation periods: after 1 day of water storage (Base) and after 20,000 thermocycles (TC 20k). For the push-out test, simulated post spaces were prepared in single-rooted human premolars. The specimens were sectioned perpendicular to the long axis into 2 mm-thick slices and then subjected to push-out testing to assess the bond strength of the dentin?resin cement?fiber post complex. No significant differences in bonding performance were found between Base and TC 20k. These findings suggest that universal adhesives used for pretreatment of multiple substrates in fiber post cementation can provide not only strong but also durable adhesion over time. en-copyright= kn-copyright= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiyamaKenraro en-aut-sei=Akiyama en-aut-mei=Kenraro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsujimotoAkimasa en-aut-sei=Tsujimoto en-aut-mei=Akimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Dental Biomaterials, Graduate School of Dentistry, Tohoku University kn-affil= affil-num=3 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=4 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=6 en-affil=Department of Operative Dentistry, School of Dentistry, Aichi Gakuin University kn-affil= affil-num=7 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=bonding performance kn-keyword=bonding performance en-keyword=universal adhesive kn-keyword=universal adhesive en-keyword=fiber post kn-keyword=fiber post en-keyword=luting materials kn-keyword=luting materials en-keyword=root dentin kn-keyword=root dentin END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=10464 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Liquid?liquid phase separation by caged coacervating peptides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liquid?liquid phase separation is an important biomolecular process in the formation of membraneless intracellular organelles that has inspired the development of artificial droplet systems. We developed caged coacervating peptides (CCPs) based on a histidine-rich squid beak protein sequence. The peptides were caged with a photodeprotectable (7-diethylaminocoumarin-4-yl)methoxycarbonyl group. The CCPs formed coacervates in the caged state and were partially dispersed upon blue-light irradiation. Photo-uncaging occurred rapidly, inducing coacervate dispersion. A mutant CCP with reduced π?π interactions exhibited efficient photo-dependent disassembly and enabled the encapsulation and release of a fluorescently labeled adenosine 5′-triphosphate (Bodipy-ATP) upon irradiation. These CCPs offer an efficient light-controlled approach for biomolecular encapsulation within coacervates and targeted drug delivery. en-copyright= kn-copyright= en-aut-name=BandoAkinari en-aut-sei=Bando en-aut-mei=Akinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanazakiYuuki en-aut-sei=Kanazaki en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TojoRika en-aut-sei=Tojo en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Caged coacervating peptide kn-keyword=Caged coacervating peptide en-keyword=Liquid?liquid phase separation kn-keyword=Liquid?liquid phase separation en-keyword=Light kn-keyword=Light END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=558 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of contact-active antibacterial properties of cetylpyridinium chloride?graphene oxide coatings on dental restorative and titanium surfaces: an in vitro study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Biofilm formation on dental restorative materials and implant surfaces plays a central role in the development of dental caries, periodontal disease, and peri-implantitis. Durable antimicrobial surface treatments that inhibit bacterial adhesion and biofilm formation remain a significant unmet need in restorative and implant dentistry. Therefore, this study aimed to develop a composite coating combining cetylpyridinium chloride and graphene oxide, and to evaluate its durable antibacterial surface modification under in vitro conditions.
Methods A composite coating consisting of cetylpyridinium chloride and graphene oxide was prepared and applied to composite resin and titanium surfaces. Antibacterial activity against Streptococcus mutans and Porphyromonas gingivalis was evaluated using adenosine triphosphate assays and fluorescence-based live/dead staining. Coating retention after washing and air-drying was assessed by optical microscopy and Raman spectroscopy.
Results Cetylpyridinium chloride-graphene oxide-coated surfaces showed a significant reduction in bacterial viability compared with phosphate-buffered saline, ethanol, and cetylpyridinium chloride-only controls. Antibacterial effects were maintained after rinsing and air-drying on both composite resin and titanium surfaces. Raman spectroscopy confirmed the persistence of characteristic graphene oxide bands after washing, indicating stable retention of the coating on the material surfaces.
Conclusions Cetylpyridinium chloride?graphene oxide coatings demonstrate sustained surface-associated antibacterial activity against key cariogenic and periodontal pathogens and remain stably adhered to common dental restorative and implant materials after washing. These findings suggest that cetylpyridinium chloride?graphene oxide coatings may serve as a durable contact-active surface modification strategy to reduce biofilm formation associated with dental caries and peri-implantitis. en-copyright= kn-copyright= en-aut-name=OkuboKeisuke en-aut-sei=Okubo en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanoGen en-aut-sei=Kano en-aut-mei=Gen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KomodaMasato en-aut-sei=Komoda en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamataHideyuki en-aut-sei=Kamata en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Field of Medical Development, 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Wash-resistant antibacterial coating kn-keyword=Wash-resistant antibacterial coating en-keyword=Graphene oxide kn-keyword=Graphene oxide en-keyword=Cetylpyridinium chloride kn-keyword=Cetylpyridinium chloride en-keyword=Oral pathogenic bacteria kn-keyword=Oral pathogenic bacteria END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=7 article-no= start-page=3143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CXCR2-Dependent Infiltration of Tumor-Associated Neutrophils Is Linked to Enhanced CD8+ T Cell Effector Function and Reduced Lung Metastasis in 4T1 Breast Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Triple-negative breast cancer (TNBC) is characterized by prominent neutrophil infiltration; however, its significance remains controversial. Here, we investigated the role of neutrophil chemoattractant receptors in TNBC progression and metastasis. In contrast to wild-type (WT), Fpr1?/?, and Fpr2?/? mice, neutrophils were almost completely absent in 4T1 tumors from Cxcr2?/? mice, indicating a dominant role for CXCR2 in the recruitment of tumor-associated neutrophils, leading us to use Cxcr2?/? mice for further studies. Primary tumor growth was comparable between WT and Cxcr2?/? mice, whereas lung metastasis was significantly increased in Cxcr2?/? mice, with reduced expression of inflammatory cytokines, chemokines and cytotoxic molecules, including granzyme B and perforin, in primary tumors and metastatic lungs of Cxcr2?/? mice. In vitro, WT, but not Cxcr2?/?, neutrophils enhanced CD8+ T cell activation, partly via ICAM-1, and directly induced tumor cell death, supporting their anti-tumor function. To assess clinical relevance, transcriptomic data were analyzed. High neutrophil infiltration combined with elevated CXCR2 expression, and to a lesser extent CXCR1 expression, was associated with improved prognosis in patients with basal-like BC that largely overlaps with TNBC. Collectively, these findings suggest that CXCR2-mediated neutrophil recruitment exerts protective, anti-tumor effects and may represent a new prognostic marker for TNBC patients. en-copyright= kn-copyright= en-aut-name=LiTiantian en-aut-sei=Li en-aut-mei=Tiantian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TianMiao en-aut-sei=Tian en-aut-mei=Miao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishidaGakushi en-aut-sei=Nishida en-aut-mei=Gakushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=neutrophils kn-keyword=neutrophils en-keyword=CD8+ T cells kn-keyword=CD8+ T cells en-keyword=chemokines kn-keyword=chemokines en-keyword=chemokine receptors kn-keyword=chemokine receptors en-keyword=tumor microenvironment kn-keyword=tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=4 article-no= start-page=760 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=The Role of Nitrate-Reducing Bacteria Isolated from Helicobacter pylori-Infected Individuals in Gastric Cancer Development en-subtitle= kn-subtitle= en-abstract= kn-abstract=Helicobacter pylori is a Gram-negative bacterium that inhabits the gastric mucosa, with a global prevalence in humans of approximately 40%. It is likely the cause of 90% of gastric cancer (GC) cases and thus considered the most prominent driver of GC development. However, during gastric mucosal atrophy, other bacteria such as nitrate-reducing bacteria (NRB) also proliferate. In this study, we isolated NRB from patients with gastritis and GC to examine their effects on the epithelial cell cycle and production of various cytokines in monocytic cell lines. Bacterial counts (excluding H. pylori and NRB) increased with the progression of gastric mucosal atrophy and were significantly higher in patients with GC. Gastric epithelial cell lines were stimulated with isolated NRB, and the proportion of cells in each cell cycle was measured. Strains from patients with open-type gastritis progressed more rapidly through cell cycles than those from patients with GC. NRB isolated from gastric cancer had high nitrate-reducing activity. Thus, NRB may contribute to GC progression during H. pylori-induced carcinogenesis. Therefore, evaluating gastric atrophy and microbiota may be important for managing the risk of GC. en-copyright= kn-copyright= en-aut-name=KuwagiSerika en-aut-sei=Kuwagi en-aut-mei=Serika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KomatsubaraMarina en-aut-sei=Komatsubara en-aut-mei=Marina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkanoueShyoutarou en-aut-sei=Okanoue en-aut-mei=Shyoutarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeAkari en-aut-sei=Watanabe en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YokotaKenji en-aut-sei=Yokota en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Himeji Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Bacteriology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Health Care and Rehabilitation, Institute of Biomedical Sciences, Graduate School, Tokushima University kn-affil= affil-num=9 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= en-keyword=Helicobacter pylori infection kn-keyword=Helicobacter pylori infection en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=nitrate-reducing bacteria kn-keyword=nitrate-reducing bacteria en-keyword=gastritis kn-keyword=gastritis 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=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suppression of salt-enhanced apoplastic flow by salicylic acid in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Salinity enhances apoplastic flow, resulting in an increment of Na+ uptake and a lower K+/Na+ ratio. Salicylic acid (SA) plays an important role in improving salinity tolerance in plants. The effect of exogenous SA on apoplastic flow in salt-treated rice seedlings was studied using an apoplastic tracer, 8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS) in light. Application of NaCl at 25 mM to the hydroponic solution significantly increased PTS uptake, while 25 mM NaCl did not affect seedling growth. Application of 25 mM NaNO3 increased PTS uptake to the same degree. Salinity significantly increased sodium (Na+) content but had no significant effect on potassium (K+) content, resulting in a lower K+/Na+ ratio. The application of SA at 0.05 mM and 0.1 mM to the hydroponic solution reduced Na-enhanced PTS uptake. Salicylic acid at 0.05 mM and 0.1 mM significantly reduced Na+ content and slightly increased K+ content in the shoots of rice seedlings, resulting in a higher K+/Na+ ratio. However, SA at up to 0.1 mM did not increase SA contents in shoots under salt stress. These results suggest that exogenous SA reduces Na+ uptake by suppressing Na+-enhanced apoplastic flow in rice seedlings. These findings provide insight into modulation of Na+ transport pathways from roots to shoots by SA and may allow us to utilize brackish water for rice cultivation and to improve salt-tolerant rice through suppression of salt-enhanced apoplastic flow by chemicals such as salicylic acid. en-copyright= kn-copyright= en-aut-name=GalibMd.

DHL with MYC and BCL6 (DH-BCL6) can also occur. The differences among these three DLBCL/HGBCL subtypes have not yet been definitively determined.
Methods and Results: This study characterized the clinicopathological features and transcriptomic profiles of a series of 101 cases of DLBCL/HGBCL that were subclassified according to MYC, BCL2 and BCL6 FISH data, including cell-of-origin (COO)-like, molecular high-grade (MHG)-like and double-hit/dark-zone (DHIT/DZsig)-like signatures. DLBCL/HGBCL-DH-BCL2 was characterized by higher HGBCL morphology, CD10 positivity, GCB Hans's, GCB COO and MHG molecular subtype. DLBCL/HGBCL-TH had higher LDH levels and worse overall survival. DLBCL/HGBCL-DH-BCL6 had higher MUM1 expression, non-GCB Hans', ABC/Unclassified COO, non-MHG and low DHIT/DZ signatures. Transcriptomic analysis showed that DLBCL/HGBCL-DH-BCL2 and DLBCL/HGBCL-TH were close but separated from DLBCL/HGBCL-DH-BCL6. Gene set enrichment analysis (GSEA) revealed different levels of enrichment between the subtypes.
Conclusions: DLBCL/HGBCL-DH-BCL6 differs from the DLBCL/HGBCL-DH-BCL2, and the DLBCL/HGBCL-TH is associated with the worst survival. Analysis of all three genes of MYC, BCL2 and BCL6 is recommended in the context of DLBCL/HGBCL diagnosis. en-copyright= kn-copyright= en-aut-name=MiyaokaMasashi en-aut-sei=Miyaoka en-aut-mei=Masashi

VANET Authentication en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vehicular Ad Hoc Network (VANET) is a fundamental component of the intelligent transportation systems (ITS), providing critical road information to users. However, the volatility of VANETs creates significant vulnerabilities from malicious actors. Thus, verifying joining entities is crucial to maintaining the VANET’s communication security. Authentication delays must stay below 100 ms to meet VANET requirements, posing a major challenge for security. Our previous research introduced a Kerberos?Blockchain (KBC) authentication system that contains two main components separately: Authentication Server (AS) and Ticket Granting Server (TGS). However, this KBC architecture required an additional server to accommodate increasing vehicle volumes in urban environments, leading to higher infrastructure costs. This paper presents an integrated authentication server that merges AS and TGS into a Combined Server (CBS) while retaining blockchain security. We evaluate it using OMNeT++ with SUMO for traffic simulation and Ganache for blockchain implementation. Results show that CBS removes the need for an extra server while keeping authentication delays under 100 ms. It also improves throughput by 104% and reduces signaling overhead by 45% compared to KBC. By optimizing authentication without compromising security, the integrated server greatly enhances the cost-effectiveness and efficiency of VANET systems. en-copyright= kn-copyright= en-aut-name=RahayuMaya en-aut-sei=Rahayu en-aut-mei=Maya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HossainMd.

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

However, sample preparation and quality control remain challenging, as current approaches typically rely on dissecting tissues containing mixed cell populations or using flow cytometry to isolate fluorescently labeled cells. Here we present a simple and reliable method for RNA-seq of chromatophores (pigment cells) by manually isolating cells based on their natural pigmentation. We analyzed four chromatophore types?melanophores, xanthophores, iridophores, and leucophores?in medaka (Oryzias latipes). Remarkably, as few as 100 cells per type yielded reasonably high-quality transcriptomes sufficient to identify differentially expressed genes (DEGs). Furthermore, this method was successfully applied to a non-model medaka species, O. woworae, which shares the same four chromatophore types. Our approach enables efficient, low-cost, and cross-species transcriptome analysis of chromatophores without requiring transgenic markers or flow cytometry. en-copyright= kn-copyright= en-aut-name=GodaMakoto en-aut-sei=Goda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyagiAsuka en-aut-sei=Miyagi en-aut-mei=Asuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiwakaKeisuke en-aut-sei=Sugiwaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeMasakatsu en-aut-sei=Watanabe en-aut-mei=Masakatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Bessho‐UeharaManabu en-aut-sei=Bessho‐Uehara en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HibiMasahiko en-aut-sei=Hibi en-aut-mei=Masahiko 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=TanakaRieko en-aut-sei=Tanaka en-aut-mei=Rieko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MasengiKawilarang W.

Based on these records, the ground velocity structures were estimated. The results yielded solutions indicating the depth of the top of the seismic base layer (equivalent to 3 km/s layer) ranges from 140 to 300 m, while the depth of the top of the engineering basement layer (equivalent to 0.6 km/s layer) is approximately about 13?14 m. The shallow exploration results also suggested the possible presence of an inversion layer. These estimated velocity structure models provided a reasonable explanation for the observed phase velocities. en-copyright= kn-copyright= en-aut-name=YAMADANobuyuki en-aut-sei=YAMADA en-aut-mei=Nobuyuki kn-aut-name=山田伸之 kn-aut-sei=山田 kn-aut-mei=伸之 aut-affil-num=1 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Science and Technology, Kochi University kn-affil=高知大学理工学部地球環境防災学科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院環境生命自然科学学域 en-keyword=Okayama Plain kn-keyword=Okayama Plain en-keyword=Kojima Bay kn-keyword=Kojima Bay en-keyword=Microtremor array exploration kn-keyword=Microtremor array exploration en-keyword=S-wave velocity structure model kn-keyword=S-wave velocity structure model END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=5 article-no= start-page=2339 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concentration-Dependent Synergistic Interfacial Interactions Between Multifunctional Acrylate and Silane Coupling Agents in an Organic?Inorganic Nanohybrid Material en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synergistic effects of a multifunctional acrylate and a long-chain silane coupling agent were investigated in an organic?inorganic nanohybrid material. We tested the bond strength of nanohybrid composites treated with experimental primers containing silane coupling agents?3-methacryloxypropyl trimethoxysilane (γ-MPTS) or 8-methacryloxyoctyl trimethoxysilane (8-MOTS)?with or without multifunctional acrylates?trimethylolpropane triacrylate (A-TMPT) or dipentaerythritol hexaacrylate (A-DPH). Shear bond strength was evaluated after 24 h of water storage at 37 °C. Untreated control and silane-only groups exhibited low shear bond strengths (e.g., control: 2.4 ± 2.0 MPa) and failed exclusively at the adhesive interface. While addition of A-TMPT did not significantly improve bond strength, addition of A-DPH produced significantly higher shear bond strengths. Highest strength was achieved with 30% 8-MOTS and A-DPH (22.4 ± 6.1 MPa), followed by 20% γ-MPTS and A-DPH (19.0 ± 7.0 MPa), and A-DPH groups produced cohesive failures. Regardless of the silane used (γ-MPTS or 8-MOTS), incorporating A-DPH in the primer consistently yielded superior bond strengths, indicating a promising strategy for improved adhesion for such nanohybrid systems. These findings provide new insights into optimizing resin?filler interfacial interactions and may contribute to the development of restorative materials with improved long-term clinical durability. en-copyright= kn-copyright= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KodamaNaoki en-aut-sei=Kodama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshizaneMai en-aut-sei=Yoshizane en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkiyamaKentaro en-aut-sei=Akiyama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=2 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=3 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Dental School, Okayama University kn-affil= affil-num=5 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=6 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=silane coupling kn-keyword=silane coupling en-keyword=multifunctional acrylate kn-keyword=multifunctional acrylate en-keyword=bond strength kn-keyword=bond strength en-keyword=resin kn-keyword=resin END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=e006392 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=Dental infection is associated with early relapse in patients with ANCA-associated vasculitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is a systemic autoimmune disease where infections can trigger relapses. Dental infections, being common and associated with systemic inflammation, may play a role in AAV relapse, though their impact remains unclear. We aimed to evaluate the association between severe dental infections and early relapse in patients with AAV.
Methods This retrospective cohort study included patients newly diagnosed with AAV between January 2011 and July 2022. Patients with severe dental infections requiring tooth extraction were placed in the dental infection group, while the remaining patients were assigned to the control group. The primary outcome was defined as either vasculitis relapse or all-cause mortality within 1 year of treatment initiation. Adjusted HRs (aHRs) and 95% CIs were estimated using Cox proportional hazards models.
Results A total of 93 patients were enrolled with a median age of 74 years. 41 patients (44.1%) had severe dental infections in this cohort. Over the 1-year follow-up period, 13 patients experienced a relapse and two died, resulting in a composite event rate of 20.9 per 100 person-years. Dental infection was independently associated with the composite outcome (aHR, 3.78 (95% CI 1.13 to 12.66); p=0.031). Exploratory analysis indicated that composite outcome rates were similar regardless of tooth extraction among patients with dental infections.
Conclusions Severe dental infections were associated with increased risk of early relapse or mortality in AAV. These findings highlight the importance of early dental evaluation in AAV management. en-copyright= kn-copyright= en-aut-name=NawachiShoichi en-aut-sei=Nawachi en-aut-mei=Shoichi kn-aut-name=

en-subject= kn-subject= en-title= kn-title=Prescription Support Practice for Pharmacy Students: Pre-Post Educational Intervention Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In the field of team-based care, pharmacists are vital for optimizing medication therapy. However, many medical professionals lack the opportunity to learn how to propose prescription changes with precision.
Objective: This study aimed to address this knowledge gap by developing and assessing a new educational program for pharmacy students focused on prescription support and interprofessional collaboration.
Methods: We recruited 191 fifth-year pharmaceutical students during the 2022‐2024 academic years. The program featured a 7-day intensive curriculum that included learning how to assist with prescriptions, analyzing clinical data, and engaging in role-playing exercises. A web-based questionnaire and a paper test were used to evaluate students’ awareness and knowledge both before and after the program. Statistical analyses were performed to verify the significance of changes; we utilized the Wilcoxon signed-rank test for the ordinal data derived from the specific behavioral objectives and 2-tailed paired t tests for the interval data from the knowledge tests. The magnitude of change was quantified using r for Wilcoxon tests and Cohen dz for 2-tailed t tests, with 95% CI calculated to ensure the stability and reliability of the observed results.
Results: Analysis of the primary outcome specific behavioral objectives revealed statistically significant effects across all items (Wilcoxon signed-rank test; P<.001). Effect sizes (r=0.505‐0.835) ranged from moderate to large, with particularly large effects observed in identifying contents issue (r=0.835, 95% CI 0.126-0.330; P<.001). Knowledge test scores showed significant improvement in the following 3 subjects: pharmacology (r=?0.504, 95% CI ?0.215 to 0.127; P<.001), organic chemistry (r=0.254, 95% CI ?0.148 to ?0.193; P=.004), and communication (r=0.221, 95% CI ?0.151 to ?0.190; P=.01). No significant changes were observed in pathology or pharmacokinetics.
Conclusions: This program provides strong evidence that practical, hands-on learning with hospital pharmacists helps improve pharmacy students’ professional skills and optimize pharmaceutical therapies in interprofessional care. By teaching pharmacists to effectively propose prescription changes, the program equips them to become integral members of interprofessional care, ultimately leading to optimized pharmaceutical care for patients. en-copyright= kn-copyright= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagiKenta en-aut-sei=Yagi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiShimon en-aut-sei=Takahashi en-aut-mei=Shimon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=ShinomiyaKazuaki en-aut-sei=Shinomiya en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= en-aut-name=KawadaKei en-aut-sei=Kawada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=2 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University 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 Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=6 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmaceutical Care and Clinical Pharmacy, Tokushima Bunri University kn-affil= affil-num=8 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=10 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=11 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= en-keyword=academic detailing kn-keyword=academic detailing en-keyword=pharmaceutical clinical practice kn-keyword=pharmaceutical clinical practice en-keyword=prescription support kn-keyword=prescription support en-keyword=professional education kn-keyword=professional education en-keyword=Interprofessional care kn-keyword=Interprofessional care END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=888 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TRPV2 in muscle satellite cells is crucial for skeletal muscle remodelling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal muscle remodelling relies on muscle stem cells (MuSCs) for regeneration after injury and hypertrophy in response to mechanical loading. However, the mechanisms that trigger MuSC activation and proliferation remain unclear. Transient receptor potential vanilloid 2 (TRPV2) ion channels respond to insulin-like growth factor-1 and mechanical stimuli to regulate the biological characteristics of various cells. Using a temporally inducible MuSC-specific conditional knockout (cKO) mouse, we show that TRPV2 regulates MuSC function and is essential for muscle remodelling. In cultured myofibre, MuSCs express TRPV2 and exhibit Ca2+ responses to the TRPV2 agonists 2-aminoethoxydiphenyl borate and probenecid, which are abolished upon TRPV2 deletion. TRPV2-deficient MuSCs exhibit reduced paired box 7 (Pax7) expression and impaired proliferation, suggesting TRPV2 is a factor that regulates the early stage of MuSC function. Myotube formation in MuSCs was enhanced by overexpression of TRPV2 and suppressed by TRPV2 deficiency, suggesting that TRPV2 is a factor that promotes myogenesis. Muscle-administered cardiotoxin promoted muscle regeneration and resulted in the appearance of numerous Pax7-positive MuSCs between myofibres. MuSC-specific TRPV2 cKO mice exhibit substantially impaired muscle regeneration after cardiotoxin-induced injury, drastically reducing Pax7-positive MuSCs between myofibres. In floxed mice, mechanical loading via synergist ablation induces hypertrophy and greatly increases the number of myonuclei per myofibre. In contrast, MuSC-specific TRPV2 cKO mice show no changes in myofibre thickness or nuclear number, either at baseline or after mechanical loading. Mechanical loading of floxed mice increased TRPV2+/Pax7+ double-positive MuSCs, but MuSC-specific TRPV2 cKO mice showed no change. Additionally, MuSCs exhibit Ca2+ responses to hypo-osmotic stimuli, which are suppressed by TRPV2 inhibitors and TRPV2 deletion, suggesting that MuSCs exhibit TRPV2-dependent mechanical responses. These results establish TRPV2 as a critical regulator of MuSC-mediated muscle remodelling, an important finding that may lead to therapeutic strategies for muscle repair and adaptation. en-copyright= kn-copyright= en-aut-name=ChenYanzhu en-aut-sei=Chen en-aut-mei=Yanzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatanosakaKimiaki en-aut-sei=Katanosaka en-aut-mei=Kimiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibuyaMakoto en-aut-sei=Shibuya en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DongYubing en-aut-sei=Dong en-aut-mei=Yubing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhangLidan en-aut-sei=Zhang en-aut-mei=Lidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanagawaMotoi en-aut-sei=Kanagawa en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukadaSo-ichiro en-aut-sei=Fukada en-aut-mei=So-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatanosakaYuki en-aut-sei=Katanosaka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biomedical Sciences, College of Life and Health Sciences, Chubu University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Stem Cell Regeneration and Adaptation, Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= affil-num=6 en-affil=Department of Cell Biology and Molecular Medicine, Ehime University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Laboratory of Stem Cell Regeneration and Adaptation, Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= affil-num=8 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=3303 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=Comparative efficacy of immune checkpoint inhibitor combination therapies by metastatic site in metastatic renal cell carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Few studies have investigated the efficacy of immuno-oncology (IO) combinations at different metastatic sites in renal cell carcinoma (RCC). We evaluated the differential efficacy of IO?IO and IO?tyrosine kinase inhibitor (TKI) combinations by metastatic site in metastatic RCC (mRCC). This retrospective multicenter study by the JK-FOOT Study Group included 579 patients with intermediate- or poor-risk mRCC (per International Metastatic RCC Database Consortium criteria) treated with first-line IO combinations between September 2018 and December 2024. Metastatic sites were lymph nodes, lungs, bones, liver, brain, and others. The primary endpoints were progression-free survival (PFS) and overall survival (OS); the secondary endpoint was objective response rate. Efficacy was compared between IO?IO and IO?TKI for each site. For lymph node (n = 36), lung (n = 132), or brain (n = 16) metastases, OS or PFS was not significantly different between IO?IO and IO?TKI. In bone metastases (n = 80), OS tended to favor IO?TKI (P = 0.053). In liver metastases (n = 22), OS was significantly longer with IO?TKI (P = 0.011). IO?TKI may be a more appropriate first-line option than IO?IO for mRCC with bone or liver metastases, while efficacy is similar for other sites. en-copyright= kn-copyright= en-aut-name=ToyodaShingo

Japan in Collaboration With the Intellectual Diversity for Goodness Research Consortium (INDIGO‐2019) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: People with Down syndrome (DS) have a strong genetic predisposition to Alzheimer's disease (AD). However, the clinical burden and associated risk factors in diverse, non-Western populations remain less understood. This study aimed to investigate the prevalence of dementia in Japanese adults with DS and to identify modifiable clinical factors associated with dementia.
Methods: This cross-sectional multicentre study surveyed 133 adults with DS (mean age 50.1?years) residing in 45 welfare facilities across Japan in 2019. Dementia was diagnosed by a consensus panel of physicians using established criteria (DSM-5, ICD-10, DC-LD) after comprehensive assessments, including the Japanese version of the Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID-J). Logistic regression analysis was performed to identify factors independently associated with dementia.
Results: Forty-six participants (34.6%) were diagnosed with dementia. The prevalence rose sharply with age: 0% in their 30s, 30.8% in their 40s, 31.6% in their 50s and 65.5% in their 60s. After adjusting for covariates, older age, female sex, dyslipidaemia and visual impairment were independently associated with dementia.
Conclusions: This study, the largest of its kind in Asia, confirms a high prevalence of dementia in institutionalized Japanese adults with DS. Crucially, this study is the first to identify dyslipidaemia and visual impairment as independent and potentially modifiable risk factors in this population. These findings highlight tangible targets for clinical interventions aimed at mitigating dementia risk in people with DS. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueTomokazu en-aut-sei=Inoue en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KurozumiTaku en-aut-sei=Kurozumi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwanoRyozo en-aut-sei=Kuwano en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuemitsuShigeru en-aut-sei=Suemitsu en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=4 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=7 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99825 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250618 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stimulatory and inhibitory G-protein signaling relays drive cAMP accumulation for timely metamorphosis in the chordate Ciona en-subtitle= kn-subtitle= en-abstract= kn-abstract=Larvae of the ascidian Ciona initiate metamorphosis tens of minutes after adhesion to a substratum via their adhesive organ. The gap between adhesion and metamorphosis initiation is suggested to ensure the rigidity of adhesion, allowing Ciona to maintain settlement after losing locomotive activity through metamorphosis. The mechanism producing the gap is unknown. Here, by combining gene functional analyses, pharmacological analyses, and live imaging, we propose that the gap represents the time required for sufficient cyclic adenosine monophosphate (cAMP) accumulation to trigger metamorphosis. Not only the Gs pathway but also the Gi and Gq pathways are involved in the initiation of metamorphosis in the downstream signaling cascade of the neurotransmitter GABA, the known initiator of Ciona metamorphosis. The mutual crosstalk of stimulatory and inhibitory G-proteins functions as the accelerator and brake for cAMP production, ensuring the faithful initiation of metamorphosis at an appropriate time and in the right situation. en-copyright= kn-copyright= en-aut-name=HozumiAkiko en-aut-sei=Hozumi en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TotsukaNozomu M en-aut-sei=Totsuka en-aut-mei=Nozomu M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoderaArata en-aut-sei=Onodera en-aut-mei=Arata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYanbin en-aut-sei=Wang en-aut-mei=Yanbin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiraishiAkira en-aut-sei=Shiraishi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatakeHonoo en-aut-sei=Satake en-aut-mei=Honoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HorieTakeo en-aut-sei=Horie en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HottaKohji en-aut-sei=Hotta en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SasakuraYasunori en-aut-sei=Sasakura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=2 en-affil=Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University kn-affil= affil-num=3 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=4 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=5 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=6 en-affil=Bioorganic Research Institute, Suntory Foundation for Life Sciences kn-affil= affil-num=7 en-affil=Bioorganic Research Institute, Suntory Foundation for Life Sciences kn-affil= affil-num=8 en-affil=Laboratory for Single-cell Neurobiology, Graduate School of Frontier Biosciences, Osaka University kn-affil= affil-num=9 en-affil=Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University kn-affil= affil-num=10 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=1 article-no= start-page=72 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=Preferential sacral fracture sites in fragility fractures of the pelvis type IVb and comparison of internal fixation methods: CT-based morphological mapping and finite element analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Fragility fractures of the pelvis (FFP) classified as Rommens-Hoffman type IVb are associated with spinopelvic dissociation and are generally considered to require surgical intervention. This study aimed to clarify the localization patterns of FFP type IVb and compare the biomechanical stability of different internal fixation techniques.
Methods In this retrospective study, morphologic mapping of sacral fracture lines was performed in 36 patients with FFP type IVb. Based on the mapping results, a finite element (FE) model of FFP type IVb was developed to evaluate the biomechanical stability of ilio-sacral screw (ISS) fixation, trans-sacral screw (TSS) fixation, spinopelvic fixation (SPF; On each side, L5 pedicle screw was connected to two iliac screws with a rod, and the bilateral constructs were linked using a cross-connector.), and bilateral triangular fixation (one TSS at S1 combined with SPF mentioned above) using finite element analysis (FEA).
Results Morphologic mapping showed that the sacrum fracture transverse line tended to pass between the S1-2 transverse lines. Although bilateral triangular fixation and SPF provided the highest stability in both U-type and H-type fractures, a TSS for U-type and two TSSs for H-type also demonstrated comparable levels of stability. ISS-based methods showed greater displacements.
Conclusion TSS-based fixation may provide stability comparable to bilateral triangular fixation and SPF in FFP type IVb, with less invasiveness when anatomy permits. Further studies are needed to optimize treatment strategies for this complex injury. en-copyright= kn-copyright= en-aut-name=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YorimitsuMasanori en-aut-sei=Yorimitsu en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=AndoTeruhiko en-aut-sei=Ando en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukuokaShiro en-aut-sei=Fukuoka en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MochizukiYusuke en-aut-sei=Mochizuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamakawaYasuaki en-aut-sei=Yamakawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=HanakawaShiro en-aut-sei=Hanakawa en-aut-mei=Shiro 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 Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Traumatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=7 en-affil=Department of Emergency Health Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=9 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama Saidaiji Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Fragility fractures of the pelvis kn-keyword=Fragility fractures of the pelvis en-keyword=Spinopelvic dissociation kn-keyword=Spinopelvic dissociation en-keyword=Finite element analysis kn-keyword=Finite element analysis en-keyword=Internal fixation kn-keyword=Internal fixation END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=908 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic value of right atrial strain in patients with chronic heart failure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Right ventricular dysfunction is a well-established prognostic marker in patients with heart failure (HF). However, the prognostic significance of right atrial (RA) function remains unclear. Given its sensitivity to systemic congestion, RA function may provide additional insights into HF disease progression and management. This study aimed to investigate whether RA reservoir function serves as an independent prognostic indicator in patients with chronic HF.
Methods A total of 613 patients with chronic HF and a left ventricular (LV) ejection fraction of less than 50% who underwent echocardiographic assessment at Okayama University Hospital between January 2018 and March 2023 were included (median age: 68 (58?76) years; 69% male). RA reservoir function was quantified using two-dimensional speckle-tracking echocardiography. The primary endpoint was cardiovascular death or HF-related hospitalization. Kaplan?Meier survival analysis was performed to examine the association between RA reservoir function and clinical outcomes.
Results During a median follow-up period of 41 months (range: 12?91 months), 119 patients experienced cardiac events. Compared with event-free patients, those with cardiac events exhibited a significantly larger RA maximum volume index (38 mL/m2 vs. 31 mL/m2, P??20%, even without RA volume enlargement (log-rank test, P? Conclusions In patients who experienced adverse cardiac events, a reduced RASr and an increased RA maximum volume were observed. Furthermore, a reduced RASr was independently associated with an increased risk of cardiovascular death and HF-related hospitalization in patients with chronic HF and LV dysfunction. These findings indicate that RASr may serve as a valuable prognostic marker for the risk stratification and management of chronic HF. en-copyright= kn-copyright= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiharaTakahiro en-aut-sei=Nishihara en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToruMiyoshi en-aut-sei=Toru en-aut-mei=Miyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= en-keyword=Right atrial function kn-keyword=Right atrial function en-keyword=Right atrial strain kn-keyword=Right atrial strain en-keyword=Chronic heart failure kn-keyword=Chronic heart failure en-keyword=Echocardiography kn-keyword=Echocardiography END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=5 article-no= start-page=1003 end-page=1015 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Claudin-18 expression in gastric type adenocarcinoma and HPV-associated adenocarcinoma of the uterine cervix en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: Claudin-18 (CLDN18) is both a marker for the gastric phenotype and a therapeutic target. However, little is known about its immunoexpression in endocervical adenocarcinomas (ECAs), particularly as detected using the clone 43-14A antibody, or about the gene expression of its isoforms in ECAs.
Methods and results: We examined CLDN18, HIK1083, p16 and Rb expression by immunohistochemistry and high-risk human papillomavirus (HR-HPV) mRNA by in situ hybridization (ISH) in 121 ECAs, including 35 HPV-independent adenocarcinomas (gastric type [GAS], n?=?24; non-GAS, n?=?11) and 86 HPV-associated ECAs. We also analysed mRNA expression of the CLDN18.1 (lung type) and CLDN18.2 (gastric type) isoforms by quantitative polymerase chain reaction (qPCR) in selected cases. CLDN18 positivity was detected in 8/24 (33%) GASs, 0/11 (0%) non-GASs and 2/86 (2%) HPV-associated ECAs, with positivity defined as staining in ?75% of tumour cells, as in gastric cancer. When a 5% cut-off was used, CLDN18 positivity was detected in 22/24 (92%) GASs, 0/11 (0%) non-GASs and 6/86 (7%) HPV-associated ECAs; CLDN18 expression was thus significantly associated with GAS histology (P? Conclusions: CLDN18 (43-14A) emerged as a potential diagnostic and therapeutic marker for GAS. A minor subset of HPV-associated ECAs also can be immunoreactive for CLDN18 and express CLDN18.2 mRNA, suggesting divergent gastric phenotypic differentiation. The caution is that GAS and HPV-associated ECAs can share overlapping histological features and similar expression of CLDN18 and p16. en-copyright= kn-copyright= en-aut-name=YasutakeNobuko en-aut-sei=Yasutake en-aut-mei=Nobuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokawaYuki en-aut-sei=Yokawa en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MishimaRiri en-aut-sei=Mishima en-aut-mei=Riri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KomamizuMisato en-aut-sei=Komamizu en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KugaRyosuke en-aut-sei=Kuga en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=JiromaruRina en-aut-sei=Jiromaru en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawatokoShinichiro en-aut-sei=Kawatoko en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SonodaKenzo en-aut-sei=Sonoda en-aut-mei=Kenzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YahataHideaki en-aut-sei=Yahata en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatoKiyoko en-aut-sei=Kato en-aut-mei=Kiyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OdaYoshinao en-aut-sei=Oda en-aut-mei=Yoshinao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=2 en-affil=Department of Pathology and Oncology, Graduate School of Medicine, Dentistry & Pharmaceutical Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Oncology, Graduate School of Medicine, Dentistry & Pharmaceutical Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Oncology, Graduate School of Medicine, Dentistry & Pharmaceutical Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences Kyushu University Fukuoka Japan kn-affil= affil-num=6 en-affil=Department of Otorhinolaryngology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=8 en-affil=Department of Medicine and Clinical Science, Kyushu University Beppu Hospital kn-affil= affil-num=9 en-affil=Department of Gynecology, Kyushu University Beppu Hospital kn-affil= affil-num=10 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=11 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=12 en-affil=Department of Anatomic Pathology, Pathological Sciences, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=13 en-affil=Department of Pathology and Oncology, Graduate School of Medicine, Dentistry & Pharmaceutical Science, Okayama University kn-affil= en-keyword=claudin-18 kn-keyword=claudin-18 en-keyword=endocervical adenocarcinoma kn-keyword=endocervical adenocarcinoma en-keyword=gastric type kn-keyword=gastric type en-keyword=human papillomavirus kn-keyword=human papillomavirus en-keyword=p16 kn-keyword=p16 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=7 article-no= start-page=e87334 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Challenge of Diagnosing Scirrhous Gastric Cancer by Endoscopic Biopsy: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Scirrhous gastric cancer, also known as linitis plastica, is a rare and aggressive subtype of gastric carcinoma that poses significant diagnostic challenges due to its submucosal infiltration and often normal-appearing mucosa. We report a case involving a 30-year-old Japanese woman who presented with a six-month history of epigastric pain and postprandial vomiting. Initial endoscopic examination revealed erythema and mucosal swelling, with limited antral distensibility and resistance during duodenal intubation. Despite 12 mucosal biopsies, histopathological examination revealed no evidence of malignancy. Given the strong clinical and endoscopic suspicion of scirrhous gastric cancer, additional deep sections and immunohistochemical staining were performed. These revealed scattered signet-ring cell carcinoma and poorly differentiated adenocarcinoma, with positive immunostaining for p53 and Ki67. The patient underwent total gastrectomy, and the diagnosis of scirrhous gastric cancer was confirmed on the resected specimen. This case highlights the importance of a high index of clinical suspicion, close collaboration between endoscopists and pathologists, and the utility of ancillary diagnostic tools, such as immunohistochemistry, in identifying subepithelial gastric malignancies that may be missed on conventional biopsy. en-copyright= kn-copyright= en-aut-name=IkedaYuka en-aut-sei=Ikeda en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=IkedaNobumasa en-aut-sei=Ikeda en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Clinic IkedaDepartment of Internal Medicine, Clinic Ikeda kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Clinic Ikeda kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=endoscopic biopsy kn-keyword=endoscopic biopsy en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=linitis plastica kn-keyword=linitis plastica en-keyword=scirrhous gastric cancer kn-keyword=scirrhous gastric cancer END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=2 article-no= start-page=e70154 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260217 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mitrofanoff Appendicovesicostomy With Boari Flap for Complete Female Urethral Transection: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Female urethral complete transection caused by pelvic trauma is extremely rare, and no standard management has been established when urethral reconstruction is not feasible.
Case Presentation: A woman in her twenties sustained an open pelvic fracture with perineal injury due to a traffic accident. Complete urethral transection was identified, and a suprapubic cystostomy was placed. After staged vaginal reconstruction and bladder function evaluation, a Mitrofanoff appendicovesicostomy was performed. Because the appendix was not enough to reach the umbilicus, a Boari flap was created to compensate for the length. Urodynamic evaluation showed improvement from a preoperative high-pressure bladder to increased compliance postoperatively, though pharmacological management was still required. Postoperatively, the patient achieved stable clean intermittent catheterization without complications.
Conclusion: The Mitrofanoff procedure can be an effective option in female urethral injuries where reconstruction is impossible. The addition of a Boari flap may expand its applicability by overcoming conduit length limitations. en-copyright= kn-copyright= en-aut-name=MoriKohei en-aut-sei=Mori en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya 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=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=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=YamasakiYuichiro en-aut-sei=Yamasaki en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Kanagawa Children's Medical Center kn-affil= affil-num=10 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Boari flap kn-keyword=Boari flap en-keyword=female urethral transection kn-keyword=female urethral transection en-keyword=Mitrofanoff kn-keyword=Mitrofanoff END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=4591 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Calcium ions play a critical role in calcification of Corynebacterium matruchotii en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dental calculus is a hardened deposit composed of calcium phosphate precipitated within dental plaque. While the involvement of dental calculus in the progression of periodontal disease is well established, many aspects of its formation process remain poorly understood. In this study, we focused on Corynebacterium matruchotii, a key bacterium involved in dental calculus formation, and investigated the role of calcium ions in calcification, as well as the associated internal and external changes in the bacterium through long-term observation. In the absence of calcium ions, no intracellular calcification was observed, and the lipid bilayer with the formation of holes in bacterial body was evident. In contrast, in the presence of calcium ions, lipid bilayer remained intact, and intracellular needle- and plate- like crystals were formed. Furthermore, calcified C. matruchotii showed increased flocculation compared to non-calcified C. matruchotii. These results indicate that the influx of calcium ions is essential for intracellular calcification. Calcium ions entry appears to reinforce the integrity of the lipid bilayer, providing a stable intracellular environment conductive to calcification. Moreover, calcified C. matruchotii may contribute to the nucleation of dental calculus by forming aggregates composed of both bacterial components and calcified material. en-copyright= kn-copyright= en-aut-name=OharaNaoko en-aut-sei=Ohara en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaMidori en-aut-sei=Ogawa en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TosaIkue en-aut-sei=Tosa en-aut-mei=Ikue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoSerina en-aut-sei=Ono en-aut-mei=Serina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaitoMitsumasa en-aut-sei=Saito en-aut-mei=Mitsumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Operative Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Microbiology, School of Medicine, University of Occupational and Environmental Health kn-affil= affil-num=3 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Operative Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Microbiology, School of Medicine, University of Occupational and Environmental Health kn-affil= affil-num=7 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Calcification kn-keyword=Calcification en-keyword=Corynebacterium matruchotii kn-keyword=Corynebacterium matruchotii en-keyword=Dental calculus kn-keyword=Dental calculus en-keyword=Calcium ions kn-keyword=Calcium ions END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=2 article-no= start-page=444 end-page=451 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=Interactive Effects of Maximum Daytime and Minimum Nighttime Temperatures on Spinach Growth and Physiological Characteristics en-subtitle= kn-subtitle= en-abstract= kn-abstract=High temperatures restrict spinach growth, and the plant’s growth and physiological responses to heat remain poorly understood. It remains unclear whether high daytime or elevated nighttime temperatures have a more negative impact on spinach growth. In addition, the interaction effect of maximum daytime and minimum nighttime temperatures on spinach growth remains unknown. This study was conducted to address these issues. Spinach was grown in controlled environments under four temperature treatments: 30 and 20 °C (T30/20), 30 and 25 °C (T30/25), 35 and 20 °C (T35/20), and 35 and 25 °C (T35/25). These treatments represent the maximum daytime temperature and minimum nighttime temperature, respectively, and were maintained for 45 days. Plant growth characteristics were monitored, and the physiological responses to temperature regimes were assessed. The results show that compared with T30/20, dry matter production decreased by 15.4% with increased nighttime temperature (T30/25), decreased by 42.3% with increased daytime temperature (T35/20), and decreased by 57.7% when both daytime and nighttime temperatures were increased (T35/25). However, there was no statistically significant interaction effect (P > 0.05) between daytime maximum and nighttime minimum temperatures on plant biomass production variables. In comparison with T30/20, the T35/25 treatment increased significantly plant stomatal conductance, stomatal apertures, transpiration rate, and leaf temperature during heat waves. The T35/25 treatment also decreased the quantum efficiency in light compared with the other treatments. Plant biomass production did not improve with the T35/20 and T35/25 treatments, likely as a result of a decoupling of photosynthesis and stomatal conductance during heat waves. Overall, these results reveal that maximum daytime and minimum nighttime temperatures exert additive effects on spinach growth. en-copyright= kn-copyright= en-aut-name=SambaNethone en-aut-sei=Samba en-aut-mei=Nethone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkasakaHisao en-aut-sei=Akasaka en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Hikawa-EndoMinori en-aut-sei=Hikawa-Endo en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamaYoko en-aut-sei=Miyama en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Food and Agricultural Sciences, Fukushima University kn-affil= affil-num=2 en-affil=The United Graduate School of Agricultural Sciences, Iwate University, Iwate, 020-8550, Japan; and Iwate Agricultural Research Center, Kenpoku Agricultural Research Institute kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Food and Agricultural Sciences, Fukushima University, Fukushima, 960-1296, Japan; and The United Graduate School of Agricultural Sciences, Iwate University kn-affil= en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=quantum efficiency kn-keyword=quantum efficiency en-keyword=stomatal aperture kn-keyword=stomatal aperture en-keyword=stomatal conductance kn-keyword=stomatal conductance en-keyword=transpiration kn-keyword=transpiration END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=11 article-no= start-page=e97584 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Psoas Abscess Diagnosed With Oral Bacteria as the Causative Pathogen en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of a psoas abscess in an 87-year-old woman, in which oral commensal bacteria may have disseminated hematogenously from a chronic oral infection site and served as the causative pathogens. The patient presented with persistent left buttock pain, fever, and swelling, and imaging revealed a fracture of the left iliac bone with an associated psoas abscess. Bacterial cultures identified Streptococcus oralis and Pseudomonas aeruginosa. Her symptoms improved following antibiotic therapy and CT-guided drainage. Although the presence of P. aeruginosa in the oral cavity is generally considered transient, it has been isolated from the oral cavities of elderly and immunocompromised individuals. In the absence of lacerations or other direct portals of entry, and considering the identification of both pathogens, the oral cavity was regarded as the most likely source of infection. This case highlights the importance of correlating culture results with the most probable source of infection to improve the prognosis of systemic infections. en-copyright= kn-copyright= en-aut-name=UmemoriKoki en-aut-sei=Umemori en-aut-mei=Koki 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=YaoMayumi en-aut-sei=Yao en-aut-mei=Mayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaKoji en-aut-sei=Fujita en-aut-mei=Koji 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=Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Dentistry and Dental Surgery, Tsuyama Central Hospital kn-affil= affil-num=4 en-affil=General Internal Medicine and Infectious Diseases, Tsuyama Central Hospital kn-affil= affil-num=5 en-affil=Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine kn-affil= en-keyword=hematogenous spread kn-keyword=hematogenous spread en-keyword=oral diseases kn-keyword=oral diseases en-keyword=oral health care kn-keyword=oral health care en-keyword=pseudomonas aeruginosa kn-keyword=pseudomonas aeruginosa en-keyword=psoas muscle abscess kn-keyword=psoas muscle abscess en-keyword=streptococcus oralis kn-keyword=streptococcus oralis END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=123 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Streamlined Radiosynthesis of [18F]Fluproxadine (AF78): An Unprotected Guanidine Precursor Enables Efficient One-Step, Automation-Ready Labeling for Clinical Use en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: [18F]Fluproxadine (formerly [18F]AF78) is a PET radiotracer targeting the norepinephrine transporter (NET) with potential applications in cardiac, neurological, and oncological imaging. Its guanidine moiety, while essential for NET binding, presents major radiosynthetic challenges due to high basicity and the harsh deprotection conditions required for protected precursors. Previous methods relied on multistep procedures, strong acids, and complex purification, limiting clinical translation. This study aimed to develop a practical one-step radiosynthesis suitable for routine and automated production. Methods: A direct SN2-type nucleophilic [18F]fluorination was performed using an unprotected guanidine precursor to eliminate deprotection steps. Reaction parameters, including the base system, solvent composition, precursor concentration, and temperature, were optimized under conventional and microwave heating. Radiochemical conversion (RCC) and operational robustness were evaluated, and purification strategies were assessed for automation compatibility. Results: Direct [18F]fluorination using the unprotected precursor reduced the total synthesis time to 60?70 min. Optimal conditions employed a tert-butanol/acetonitrile (4:1) solvent system with K2CO3/Kryptofix222, affording RCC up to 33% under conventional heating. Microwave irradiation further improved efficiency, achieving RCC of up to 64% within 1.5 min at 140 °C. The method showed broad tolerance to variations in the base molar ratio and precursor concentration and enabled isocratic HPLC purification. Conclusions: This one-step radiosynthesis overcomes longstanding challenges in [18F]fluproxadine production by eliminating harsh deprotection and enabling high-yield, automation-ready synthesis, thereby improving clinical feasibility. en-copyright= kn-copyright= en-aut-name=ChenXinyu en-aut-sei=Chen en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhtaKaito en-aut-sei=Ohta en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraHiroyuki en-aut-sei=Kimura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YagiYusuke en-aut-sei=Yagi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=NoseNaoko en-aut-sei=Nose en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkehiMasaru en-aut-sei=Akehi en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaneTomohiko en-aut-sei=Yamane en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WernerRudolf A. en-aut-sei=Werner en-aut-mei=Rudolf A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Agency for Health, Safety and Environment, Kyoto University kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Molecular Imaging Research, Kobe City Medical Center General Hospital kn-affil= affil-num=9 en-affil=Department of Nuclear Medicine, LMU Hospital, and German Cancer Consortium (DKTK), Partner Site Munich, Ludwig-Maximilians-University of Munich kn-affil= affil-num=10 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=norepinephrine transporter kn-keyword=norepinephrine transporter en-keyword=positron emission tomography kn-keyword=positron emission tomography en-keyword=[18F]AF78 kn-keyword=[18F]AF78 en-keyword=[18F]fluproxadine kn-keyword=[18F]fluproxadine en-keyword=radiolabeling kn-keyword=radiolabeling END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=17960 end-page=17970 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=FEM-Based Design and Characterization of a Millimeter-Scale Piezoelectric Resonance Force Sensor en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents a millimeter-scale piezoelectric effect-based force sensor that uses the change in its resonant frequency as the detection principle for high sensitivity and a wide measurement range. Such characteristics are suited for robot hand applications that not only detect small forces but also handle large payloads. We develop a methodology to estimate the relationship between applied force and resonant frequency shift by combining classical contact theory and finite element method (FEM) analysis. Although this relationship is non-linear, the designability of sensitivity and measurement range is demonstrated by the simulation. The simulation results based on the method are verified, showing good agreement with the experimental results. The static characteristics, including sensitivity, standard deviation, and resolution, are evaluated using prototype sensors with characteristic lengths ranging from 1 mm to 4 mm. The 4-mm model has a measurement range of 77 mN to 300 N, and the smallest model, which is one of the smallest force sensors suitable for practical implementation, has a measurement range of 9 mN to 20 N. en-copyright= kn-copyright= en-aut-name=YamazakiAoto en-aut-sei=Yamazaki en-aut-mei=Aoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkidukiTakuma en-aut-sei=Akiduki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HonnaAtsuo en-aut-sei=Honna en-aut-mei=Atsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitazakiMichiteru en-aut-sei=Kitazaki en-aut-mei=Michiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MashimoTomoaki en-aut-sei=Mashimo en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Mechanical Engineering, Toyohashi University of Technology kn-affil= affil-num=2 en-affil=Department of Mechanical Engineering, Toyohashi University of Technology kn-affil= affil-num=3 en-affil=Riccoh Company Ltd. kn-affil= affil-num=4 en-affil=Department of Computer Science and Engineering, Toyohashi University of Technology kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Force sensors kn-keyword=Force sensors en-keyword=piezoelectric effect kn-keyword=piezoelectric effect en-keyword=resonators kn-keyword=resonators en-keyword=transducers kn-keyword=transducers en-keyword=ultrasonics kn-keyword=ultrasonics END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1716939 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural analysis of PSI-ACPI and PSII-ACPII supercomplexes from a cryptophyte alga Rhodomonas sp. NIES-2332 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Light energy is converted to chemical energy by two photosystems (PSI and PSII) in complex with their light-harvesting complex proteins (LHCI and LHCII) in photosynthesis. Rhodomonas is a member of cryptophyte alga whose LHCs contain unique chlorophyll a/c proteins (ACPs) and phycobiliproteins. We purified PSI-ACPI and PSII-ACPII supercomplexes from a cryptophyte Rhodomonas sp. NIES-2332 and analyzed their structures at high resolutions of 2.08 ? and 2.17 ?, respectively, using cryo-electron microscopy. These structures are largely similar to those reported previously from two other species of cryptophytes, but exhibited some differences in both the pigment locations and subunit structures. A part of the antenna subunits of both photosystems is shifted compared with the previously reported structures from other species of cryptophytes, suggesting some differences in the energy transfer rates from the antenna to the PSI and PSII cores. Newly identified lipids are found to occupy the interfaces between the antennae and cores, which may be important for assembly and stabilization of the supercomplexes. Water molecules surrounding three iron-sulfur clusters of the PSI core are found in our high-resolution structure, some of which are conserved from cyanobacteria to higher plants but some are different. In addition, our structure of PSII-ACPII lacks the subunits of oxygen-evolving complex as well as the Mn4CaO5 cluster, suggesting that the cells are in the S-growth phase, yet the PSI-ACPI structure showed the binding of PsaQ, suggesting that it is in an L-phase. These results suggest that the S-phase and L-phase can co-exist in the cryptophytic cells. The high-resolution structures of both PSI-ACPIs and PSII-ACPIIs solved in this study provide a more solid structural basis for elucidating the energy transfer and quenching mechanisms in this group of the organisms. en-copyright= kn-copyright= en-aut-name=ZhangWenyue en-aut-sei=Zhang en-aut-mei=Wenyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoneharaNozomi en-aut-sei=Yonehara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiiMizuki en-aut-sei=Ishii en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangHaowei en-aut-sei=Jiang en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=La RoccaRomain en-aut-sei=La Rocca en-aut-mei=Romain kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsaiPi-Cheng en-aut-sei=Tsai en-aut-mei=Pi-Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiHongjie en-aut-sei=Li en-aut-mei=Hongjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkitaFusamichi en-aut-sei=Akita en-aut-mei=Fusamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cryptophytes kn-keyword=cryptophytes en-keyword=Rhodomonas kn-keyword=Rhodomonas en-keyword=photosystem I kn-keyword=photosystem I en-keyword=photosystem II kn-keyword=photosystem II en-keyword=light-harvesting complex kn-keyword=light-harvesting complex en-keyword=photosynthesis kn-keyword=photosynthesis END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TeMPRA: advancing continuing professional development in pediatric rheumatology in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In the context of the global shortage of pediatric rheumatologists, mid-career specialists who can play key roles in regional education, research, and clinical practice have become increasingly important. In Japan, the Team of Mid-career Pediatric Rheumatologists Alliance (TeMPRA) was founded in 2014 to support continuing professional development (CPD) and foster collaboration among mid-career pediatric rheumatologists. The aim of this study was to characterize the current status and future perspectives of the TeMPRA members.
Methods In 2024, a cross-sectional, web-based survey was conducted among all 37 active members of the TeMPRA across Japan. Data were collected on career trajectories, educational roles, research activities, clinical practices, and international engagement. Categorical variables were compared using appropriate statistical tests, with a significance level of 0.05.
Results Responses were obtained from 35 members (response rate: 95%). Most respondents (71%) were affiliated with university hospitals, and 60% had?>?10 years of experience in pediatric rheumatology. Compared with those working in community hospitals, respondents affiliated with university hospitals were significantly more likely to be involved in research activities (50% vs. 0%, P?=?0.0261) and global professional contributions (88% vs. 0%, P? Conclusions This nationwide survey highlights the substantial educational roles, research activities, and clinical practices of mid-career pediatric rheumatologists in Japan and suggests that the TeMPRA framework can serve as a valuable model for supporting CPD and workforce sustainability. Similar alliance-based approaches may be applicable in other countries facing comparable challenges in pediatric rheumatology. en-copyright= kn-copyright= en-aut-name=WakiguchiHiroyuki

en-title= kn-title=Impact of visceral fat area on surgical difficulty during robotic distal pancreatectomy (TAKUMI-2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Difficulty scoring systems (DSS) have been developed to quantify the surgical complexity of laparoscopic distal pancreatectomy (LDP). However, few studies have validated these systems in the context of robotic distal pancreatectomy (RDP). Moreover, the impact of body composition on RDP outcomes remains unexplored. This study aimed to investigate the risk factors of surgical difficulty in RDP, including body composition.
Methods: This retrospective study included 72 consecutive patients who underwent RDP at our institution between April 2021 and October 2024. Using a modified DSS for LDP, patients were divided into three difficulty index groups. The association between the difficulty index and outcomes was investigated. Multivariate analyses were performed to identify risk factors associated with surgical difficulty (prolonged operative time) in RDP.
Results: Patients were classified into three difficulty index groups: low (n?=?28), intermediate (n?=?25), and high (n?=?19). Operative time was significantly associated with the surgical index (P?=?0.01). Moreover, visceral fat area (VFA) was significantly correlated with operative time (r2?=?0.10, P?=?0.008). The multivariate analyses found that VFA (??100 cm2) (odds ratio [OR] 5.03, 95% confidence interval [CI] 1.32?22.4, P?=?0.02), malignancy (OR 4.92, 95% CI 1.50?18.9, P?=?0.01), and pancreatic resection on the portal vein (OR 4.14, 95% CI 1.24?15.9, P?=?0.02) were significant risk factors associated with surgical difficulty.
Conclusion: VFA could be a novel and useful factor for assessing the surgical difficulty associated with RDP. 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=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko 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=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki 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=Robotic distal pancreatectomy kn-keyword=Robotic distal pancreatectomy en-keyword=Difficulty score kn-keyword=Difficulty score en-keyword=Visceral fat area kn-keyword=Visceral fat area END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=e84161 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250515 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pseudoachalasia Due to Malignant Pleural Mesothelioma Involving the Esophagus en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of pseudoachalasia secondary to malignant pleural mesothelioma involving the esophagus. A 66-year-old man presented with progressive dysphagia, weight loss, and postprandial hiccups. Endoscopic examination showed esophageal dilation with luminal narrowing at the esophagogastric junction, but no mucosal abnormalities. Computed tomography revealed an irregular-shaped mass extending from the peri-esophagogastric junction to the retroperitoneum, accompanied by pleural effusion, right-sided hydronephrosis, and multiple hepatic lesions. Endoscopic ultrasound-guided fine-needle aspiration from the mass lesion through the esophageal lumen revealed epithelioid malignant mesothelioma. This case highlights the importance of considering malignant mesothelioma in the differential diagnosis of pseudoachalasia, particularly when imaging reveals extrinsic esophageal compression without mucosal lesions. en-copyright= kn-copyright= en-aut-name=HondaManami en-aut-sei=Honda en-aut-mei=Manami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=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=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=endoscopic ultrasound-guided fine-needle aspiration kn-keyword=endoscopic ultrasound-guided fine-needle aspiration en-keyword=esophageal diseases kn-keyword=esophageal diseases en-keyword=esophagogastroduodenoscopy (egd) kn-keyword=esophagogastroduodenoscopy (egd) en-keyword=malignant mesothelioma kn-keyword=malignant mesothelioma en-keyword=pseudoachalasia kn-keyword=pseudoachalasia END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=4 article-no= start-page=e82046 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gastrointestinal Stromal Tumors in the Stomach With Tumor Growth and Hemorrhage During Conservative Management: A Report of Two Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastrointestinal stromal tumors (GISTs) are often detected incidentally during esophagogastroduodenoscopy.

A 58-year-old man with epigastric discomfort underwent esophagogastroduodenoscopy, which revealed a reddish semi-pedunculated lesion with a whitish coating. Biopsy and imaging confirmed clear cell RCC metastasis. Contrast-enhanced computed tomography (CT) revealed a primary renal tumor with pancreatic and lymph node metastases. Despite chemotherapy treatment, the patient died after 10 months. Gastric metastases from RCC, although rare, should be considered in highly vascular gastric lesions with white coatings. Clinicians must be vigilant for metastatic diseases with atypical gastric findings. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamioTomohiro en-aut-sei=Kamio en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirataShoichiro en-aut-sei=Hirata en-aut-mei=Shoichiro 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=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=clear renal cell carcinoma kn-keyword=clear renal cell carcinoma en-keyword=esophagogastroduodenoscopy (egd) kn-keyword=esophagogastroduodenoscopy (egd) en-keyword=gastric metastasis kn-keyword=gastric metastasis en-keyword=metastatic tumor, renal cell carcinoma (rcc) kn-keyword=metastatic tumor, renal cell carcinoma (rcc) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=1877 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Surgical Procedures for Rheumatoid Forefoot Deformities on Radiographic Foot Length and Width Variations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The number of patients with rheumatoid arthritis (RA) undergoing forefoot arthroplasty has increased to better control the disease. Despite patients frequently expressing concerns regarding postoperative foot appearance and footwear-related expectations, no study has investigated postoperative changes in foot length and width in patients with RA. The aim of this study was to evaluate the effect of surgical procedures for rheumatoid forefoot deformities on variations in radiologically determined foot length and width. Methods: In total, 72 feet of 50 women and 3 men (average age: 66.7 years) underwent joint-preserving arthroplasty (n = 33) and arthrodesis of the first metatarsophalangeal joint with shortening osteotomy of the lesser metatarsals or resection arthroplasty of the lesser metatarsal heads (n = 39); procedures were carried out in our institute from August 2013 to February 2020. The mean disease duration was 23.5 years, and the average follow-up period was 17.5 months. Pre- and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA) of the first and second metatarsals (M1M2A), and IMA of the first and fifth metatarsals (M1M5A) were measured on weightbearing radiographs as well as foot length and width. We also evaluated the correlation between changes in radiographic parameters and variations in radiologically determined foot length and width. Results: Radiologically determined foot width changed significantly from 10.1 cm to 9.7 cm (p < 0.01), while no significant difference was found between pre- and postoperative radiologically determined foot length. HVA, M1M2A, and M1M5A were significantly improved after the surgery (p < 0.01, p < 0.01, and p < 0.01, respectively). A significant negative correlation was found between the variation in radiologically determined foot length and changes in HVA (r = ?0.29, p = 0.02) and M1M5A (r = ?0.23, p < 0.05), while a significant positive correlation was found between the variation in the foot width and changes in HVA (r = 0.34, p < 0.01), M1M2A (r = 0.55, p < 0.01), and M1M5A (r = 0.45, p < 0.01). There were no significant differences between operative procedures regarding variation in radiologically determined foot length and width. Conclusions: Surgical procedure for rheumatoid forefoot deformity improved radiographic parameters and reduced radiographic foot width while maintaining foot length. en-copyright= kn-copyright= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KisoYohei en-aut-sei=Kiso en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SaigaKenta en-aut-sei=Saiga en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Kurashiki Sweet Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=4 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= en-keyword=forefoot surgery kn-keyword=forefoot surgery en-keyword=foot length kn-keyword=foot length en-keyword=foot width kn-keyword=foot width en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=372 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alpha-Ketoglutarate Drives an Osteogenic and Extracellular Matrix Gene Program in Periodontal Ligament Fibroblasts via Selective Reduction of H3K27me3 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Periodontal disease damages the tissues that support teeth and can ultimately lead to tooth loss, yet effective treatments to regenerate these tissues are still limited. Recent studies have shown that substances produced during normal cellular metabolism can influence how genes are regulated, but their role in periodontal regeneration has not been fully clarified. In this study, we investigated whether alpha-ketoglutarate, a naturally occurring metabolite involved in energy production, could promote periodontal tissue regeneration. We found that alpha-ketoglutarate enhanced bone-related and extracellular matrix-related gene expression in human periodontal ligament cells by reducing a repressive gene-regulatory signal that normally suppresses these genes. Importantly, alpha-ketoglutarate did not broadly alter chromatin accessibility, indicating that its effects were mediated through selective gene regulation. Furthermore, oral administration of alpha-ketoglutarate promoted alveolar bone regeneration and collagen-rich tissue formation in a mouse model of periodontal disease. Because alpha-ketoglutarate is a naturally occurring molecule in the body, these findings suggest that metabolite-based regulation of gene activity may represent a promising and safe approach for periodontal tissue regeneration. en-copyright= kn-copyright= en-aut-name=HasegawaRyu en-aut-sei=Hasegawa en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeki en-aut-sei=Suzuki en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FahrezaRahmad Rifqi en-aut-sei=Fahreza en-aut-mei=Rahmad Rifqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsaiShin-Ho en-aut-sei=Tsai en-aut-mei=Shin-Ho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DaidoujiYoshino en-aut-sei=Daidouji en-aut-mei=Yoshino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriMasato en-aut-sei=Omori en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KajikawaTetsuhiro en-aut-sei=Kajikawa en-aut-mei=Tetsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaSatoru en-aut-sei=Yamada en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=2 en-affil=Department of Operative Dentistry, Okayama University Graduate School, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=4 en-affil=Department of Operative Dentistry, Okayama University Graduate School, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=7 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=8 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= en-keyword=alpha-ketoglutarate kn-keyword=alpha-ketoglutarate en-keyword=periodontal ligament kn-keyword=periodontal ligament en-keyword=extracellular matrix kn-keyword=extracellular matrix en-keyword=epigenetic regulation kn-keyword=epigenetic regulation en-keyword=H3K27me3 kn-keyword=H3K27me3 END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=4 article-no= start-page=715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antigen Remodeling in Colorectal Cancer: How Radiotherapy and Chemotherapy Enhance Immunotherapy Responsiveness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colorectal cancer (CRC) is traditionally considered a “cold tumor” characterized by low immunogenicity and limited responsiveness to immune checkpoint inhibitors (ICIs). However, recent findings reveal that cytotoxic modalities can reprogram this immunologically inert landscape. This review integrates these evolving concepts to guide the optimization of future treatments. Radiotherapy induces extensive DNA double-strand breaks, which may generate de novo mutations through error-prone repair while simultaneously exposing cryptic antigens via increased transcriptional instability, alternative splicing, and enhanced proteasomal processing. Chemoradiation also amplifies epigenetic and epitranscriptomic sources of neoepitope diversity, including RNA editing and stress-induced splicing alterations, expanding the immunopeptidome beyond canonical mutation-driven neoantigens. These changes collectively enhance antigen presentation and facilitate T-cell priming. Chemotherapy further reduces immunosuppressive cell populations and promotes dendritic cell activation, creating a permissive milieu for subsequent immune engagement. Clinically, the VOLTAGE studies demonstrated that long-course chemoradiotherapy can sensitize even mismatch repair?proficient rectal cancers to PD-1 blockade, yielding clinically meaningful pathological responses. In contrast, mismatch repair?deficient rectal tumors may respond completely to ICIs alone. Short-course radiotherapy combined with chemotherapy and ICIs has also shown encouraging activity in the setting of total neoadjuvant therapy. Collectively, these findings support a paradigm in which radiotherapy, chemotherapy, and epigenetic/epitranscriptomic alterations?including RNA editing?act as potent modulators of tumor antigenicity. By expanding the neoantigen repertoire and reshaping the tumor microenvironment, these strategies can transform CRC from a cold tumor into one that is increasingly responsive to immunotherapy. en-copyright= kn-copyright= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TakahashiToshiaki en-aut-sei=Takahashi en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriwakeKazuya en-aut-sei=Moriwake en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KayanoMasashi en-aut-sei=Kayano en-aut-mei=Masashi 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=colorectal cancer kn-keyword=colorectal cancer en-keyword=immunotherapy kn-keyword=immunotherapy en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=neoantigens kn-keyword=neoantigens 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=20260221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Turning pancreatic cancer from cold to hot: the promise of a p53-expressing oncolytic adenovirus (OBP-702) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic cancer remains one of the most lethal malignancies, with limited therapeutic options and poor responsiveness to immune checkpoint inhibitors (ICIs). This resistance is largely attributed to its profoundly immunosuppressive and desmoplastic tumor microenvironment (TME), characterized by low tumor mutational burden, dense stroma, and abundant immunosuppressive cell populations. Therefore, strategies capable of enhancing tumor immunogenicity and overcoming immune evasion are urgently needed. Oncolytic virotherapy is a promising approach, offering not only tumor-selective cytotoxicity, but also potent immunomodulatory effects. Of these agents, Telomelysin (OBP-301, Suratadenoturev), a telomerase-specific oncolytic adenovirus, demonstrated clinical safety but limited efficacy in refractory tumors. To address this challenge, we developed OBP-702, a next-generation, p53-armed, oncolytic adenovirus designed to augment antitumor activity. Preclinical studies have shown that OBP-702 exerts robust cytotoxicity through multiple mechanisms, including p53-mediated apoptosis and autophagy, E1A?E2F1-mediated p21 suppression, and inhibition of oncogenic KRAS pathways. Importantly, OBP-702 induces strong immunogenic cell death, activates dendritic cells, and promotes tumor-specific T-cell responses, effectively converting immunologically “cold” pancreatic tumors into “hot” tumors. OBP-702 also remodels the immunosuppressive TME by reducing granulocyte?macrophage colony-stimulating factor (GM-CSF) secretion, suppressing myeloid-derived suppressor cells (MDSCs), and targeting stromal components, such as cancer-associated fibroblasts (CAFs). These effects contribute to enhanced responses to ICIs and standard chemotherapies. Given its multifaceted antitumor functions and ability to overcome key barriers in pancreatic cancer, OBP-702 represents a highly promising therapeutic candidate. A first-in-human clinical trial evaluating endoscopic ultrasonography-guided intratumoral injection of OBP-702 is currently in preparation, expected to advance clinical translation of this novel virotherapeutic strategy. en-copyright= kn-copyright= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=UrataYasuo en-aut-sei=Urata en-aut-mei=Yasuo 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=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of 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=Oncolys BioPharma Inc 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=Oncolytic adenovirus kn-keyword=Oncolytic adenovirus en-keyword=p53 kn-keyword=p53 en-keyword=OBP-702 kn-keyword=OBP-702 en-keyword=Immunogenic cell death kn-keyword=Immunogenic cell death en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment en-keyword=Pancreatic cancer kn-keyword=Pancreatic cancer END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=12 article-no= start-page=e100138 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Streptococcal Toxic Shock Syndrome Following Intestinal Obstruction in a Patient With Crohn’s Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Streptococcal toxic shock syndrome (STSS) is a rare, life-threatening complication of invasive group A streptococcal (iGAS) infections. We report the case of a 24-year-old woman with Crohn's disease receiving immunosuppressive therapy who developed STSS following intestinal obstruction. On day 2, she developed fever, altered mental status, hypoxemia, erythema, and hypotension. Chest CT revealed bilateral pulmonary infiltrates, and blood cultures grew emm1-positive M1UK Streptococcus pyogenes, confirming STSS. Early multidisciplinary intervention resulted in rapid recovery without sequelae. This case emphasizes the importance of considering iGAS-induced STSS in septic shock, especially in immunocompromised patients, and highlights the need for prompt recognition and treatment. en-copyright= kn-copyright= en-aut-name=NishioAyano en-aut-sei=Nishio en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiguroMikako en-aut-sei=Ishiguro en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuokaYuto en-aut-sei=Matsuoka en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KanazawaTomoyuki en-aut-sei=Kanazawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Okayama University Hospital 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 Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=crohn’s disease (cd) kn-keyword=crohn’s disease (cd) en-keyword=group a streptococcus kn-keyword=group a streptococcus en-keyword=immunosuppression kn-keyword=immunosuppression en-keyword=intestinal obstruction kn-keyword=intestinal obstruction en-keyword=streptococcal toxic shock syndrome (stss) kn-keyword=streptococcal toxic shock syndrome (stss) END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=2 article-no= start-page=2301 end-page=2310 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Total thymectomy is oncologically superior to partial thymectomy in patients with thymic carcinoma: insights from a multicenter real-world data analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although total thymectomy has been the standard surgical approach for thymic epithelial tumors, an increasing number of recent reports suggest that partial thymectomy for early-stage thymomas may yield outcomes comparable to those of total thymectomy. However, whether partial thymectomy is a viable alternative for thymic carcinoma remains unclear.
Materials and methods: A total of 106 patients with thymic carcinoma underwent curative intended resection at 19 institutions between January 2010 and December 2021. Excluding 14 patients with incomplete resection, 92 patients with thymic carcinoma who underwent total (n = 73) or partial thymectomy (n = 19) were compared. Overall survival (OS) and recurrence-free survival (RFS) were analyzed using Kaplan?Meier curves and Cox proportional hazard models. Overlap weighting was applied to adjust for potential confounding factors.
Results: Among patients with clinical stage I disease, 79.3% were upstaged to stage II or higher postoperatively. Unadjusted analyses revealed no statistically significant differences in OS and RFS between the total and partial thymectomy groups, although a trend toward poorer outcomes in the partial thymectomy group was observed. After overlap weighting, partial thymectomy was associated with significantly poorer OS (P = 0.0027) and higher recurrence risk (P < 0.0001). Early postoperative recurrence occurred more frequently in the partial thymectomy group.
Conclusion: Partial thymectomy was associated with significantly worse survival and recurrence outcomes in thymic carcinoma. Given the limitations of preoperative diagnosis, total thymectomy should remain the preferred surgical approach for undiagnosed thymic epithelial tumors to achieve optimal oncologic control and minimize the risk of recurrence. en-copyright= kn-copyright= en-aut-name=HayashiTatsuya en-aut-sei=Hayashi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

derivatives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Purpose: Ascochlorin (ASC) is an antiviral antibiotic from the fermented broth of Ascochyta viciae which exerts an inhibitory effect to cancers. Its impact on immune cells has not been examined. In this study, we obtained ASC derivatives with less cytotoxicity and determined whether they affected T cells, indicating possible immune-mediated antitumour effects.
Experimental Approach: Newly synthesised ASC derivatives were screened for inhibitory effects on T-cell antigen receptor (TCR)-stimulated proliferative responses using murine CD4+ and CD8+ T cells. Two compounds were identified that exhibited >10-fold less toxicity compared with ASC. N184, the less toxic of the two, was analysed for its in vivo antitumour effects, and in vitro effects on CD8+ T-cell proliferation, survival, cytokine production and exhaustion, using microscopy, qPCR and flow cytometry.
Key Results: N184 induced limited IL-9 production in CD8+ T cells following TCR stimulation, thereby improving cell survival. It also enhanced cytokine production in the late phase of proliferation and suppressed the induction of exhaustion. N184 suppressed tumour growth in mice in a CD8+ T cell-dependent manner. The effect was partially prevented by an IL-9-neutralising antibody.
Conclusion and Implications: N184 induces differentiation of IL-9-producing CD8+ T cells in vitro and elicits antitumour immunity in an IL-9-dependent manner. en-copyright= kn-copyright= en-aut-name=ImanoNatsumi en-aut-sei=Imano en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaMikako en-aut-sei=Nishida en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokumasuMiho en-aut-sei=Tokumasu en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhaoWeiyang en-aut-sei=Zhao en-aut-mei=Weiyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaNahoko en-aut-sei=Yamashita en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UdonoHeiichiro en-aut-sei=Udono en-aut-mei=Heiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Immunology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Metabolic Immune Regulation, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Immunology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Immunology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Metabolic Immune Regulation, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Metabolic Immune Regulation, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=ascochlorin derivative kn-keyword=ascochlorin derivative en-keyword=CD8 positive T lymphocytes kn-keyword=CD8 positive T lymphocytes en-keyword=cell survival kn-keyword=cell survival en-keyword=IFN-γ kn-keyword=IFN-γ en-keyword=interleukin-9 kn-keyword=interleukin-9 en-keyword=Tc9 kn-keyword=Tc9 en-keyword=tumour immunity kn-keyword=tumour immunity END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1673581 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Binding of IgA1 and surface-expressed collagen-binding protein of Streptococcus mutans contributes to IgA nephropathy pathogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The present study was conducted to examine the interaction between collagen-binding protein (Cnm) of Streptococcus mutans and immunoglobulin (IgA) to clarify the possible involvement in IgA nephropathy (IgAN) development.
Methods: The binding of Cnm to human immunoglobulins was examined using an enzyme-linked immunosorbent assay. A nephritis-induced rat model was employed to confirm the localization of Cnm.
Results: IgA1 showed significantly greater binding ability to Cnm than to other bacterial surface proteins, and Cnm showed significantly greater binding ability to IgA1 than to other immunoglobulins. In rats administered Cnm, IgA deposition was observed in the glomerular mesangial region. Furthermore, biotin-labeled Cnm was observed in the same region as IgA deposition in the Cnm group.
Conclusions: Taken together, it is considered that following invasion into the bloodstream, Cnm binds to and forms a complex with IgA1, leading to deposition of IgA1 in renal glomeruli. en-copyright= kn-copyright= en-aut-name=MatsuokaDaiki en-aut-sei=Matsuoka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SueharaKana en-aut-sei=Suehara en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaShuhei en-aut-sei=Naka en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MisakiTaro en-aut-sei=Misaki en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagasawaYasuyuki en-aut-sei=Nagasawa en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItoSeigo en-aut-sei=Ito en-aut-mei=Seigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuehiroYuto en-aut-sei=Suehiro en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NomuraRyota en-aut-sei=Nomura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoKazuhiko en-aut-sei=Nakano en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Matsumoto-NakanoMichiyo en-aut-sei=Matsumoto-Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Nephrology, Seirei Hamamatsu General Hospital kn-affil= affil-num=5 en-affil=Department of General Internal Medicine, Hyogo Medical University kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Japan Self-Defense Force Iruma Hospital kn-affil= affil-num=7 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=8 en-affil=Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=9 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=10 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bacterial surface proteins kn-keyword=bacterial surface proteins en-keyword=collagen-binding protein kn-keyword=collagen-binding protein en-keyword=human immunoglobulins kn-keyword=human immunoglobulins en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=Streptococcus mutans kn-keyword=Streptococcus mutans END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=2 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Threshold Selection Method in Code Plagiarism Checking Function for Code Writing Problem in Java Programming Learning Assistant System Considering AI-Generated Codes en-subtitle= kn-subtitle= en-abstract= kn-abstract=To support novice learners, the Java programming learning assistant system (JPLAS) has been developed with various features. Among them, code writing problem (CWP) assigns writing an answer code that passes a given test code. The correctness of an answer code is validated by running it on JUnit. In previous works, we implemented a code plagiarism checking function that calculates the similarity score for each pair of answer codes based on the Levenshtein distance. When the score is higher than a given threshold, this pair is regarded as plagiarism. However, a method for finding the proper threshold has not been studied. In addition, AI-generated codes have become threats in plagiarism, as AI has grown in popularity, which should be investigated. In this paper, we propose a threshold selection method based on Tukey’s IQR fences. It uses a custom upper threshold derived from the statistical distribution of similarity scores for each assignment. To better accommodate skewed similarity distributions, the method introduces a simple percentile-based adjustment for determining the upper threshold. We also design prompts to generate answer codes using generative AI and apply them to four AI models. For evaluation, we used a total of 745 source codes of two datasets. The first dataset consists of 420 answer codes across 12 CWP instances from 35 first-year undergraduate students in the State Polytechnic of Malang, Indonesia (POLINEMA). The second dataset includes 325 answer codes across five CWP assignments from 65 third-year undergraduate students at Okayama University, Japan. The applications of our proposals found the following: (1) any pair of student codes whose score is higher than the selected threshold has some evidence of plagiarism, (2) some student codes have a higher similarity than the threshold with AI-generated codes, indicating the use of generative AI, and (3) multiple AI models can generate code that resembles student-written code, despite adopting different implementations. The validity of our proposal is confirmed. en-copyright= kn-copyright= en-aut-name=PermatasariPerwira Annissa Dyah en-aut-sei=Permatasari en-aut-mei=Perwira Annissa Dyah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KinariSafira Adine en-aut-sei=Kinari en-aut-mei=Safira Adine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WaiKhaing Hsu en-aut-sei=Wai en-aut-mei=Khaing Hsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Engineering Science, Akita University kn-affil= en-keyword=Java programming learning kn-keyword=Java programming learning en-keyword=JPLAS kn-keyword=JPLAS en-keyword=JUnit kn-keyword=JUnit en-keyword=code writing problem kn-keyword=code writing problem en-keyword=plagiarism kn-keyword=plagiarism en-keyword=Levenshtein distance kn-keyword=Levenshtein distance en-keyword=threshold kn-keyword=threshold en-keyword=IQR kn-keyword=IQR en-keyword=AI-generated kn-keyword=AI-generated END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=69 end-page=74 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=Effective Treatment of Advanced Hepatocellular Carcinoma with Extensive Peritoneal Dissemination Using Lenvatinib en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with hepatocellular carcinoma (HCC) and extensive peritoneal dissemination generally have a poor prognosis and are often resistant to systemic therapy. We report the case of a 47-year-old woman with HCC and massive peritoneal dissemination who presented with malignant ascites requiring repeated cell-free and concentrated ascites reinfusion therapy and peritoneovenous shunt placement, as well as malignant pleural effusion requiring pleurodesis. Combined immunotherapy with durvalumab/tremelimumab was initiated;however, disease progression was observed after three treatment courses, prompting a switch to lenvatinib therapy. Two months after initiation of lenvatinib, CT imaging demonstrated complete disappearance of arterial enhancement in the primary hepatic lesion, along with reduction in the size of peritoneal dissemination nodules. Thirteen months after switching to lenvatinib (16 months after the initial diagnosis), the alpha-fetoprotein level continued to decrease, and the disease remained stable under treatment. Despite the extremely high tumor burden, lenvatinib achieved disease stabilization and symptomatic improvement. en-copyright= kn-copyright= en-aut-name=WakatsukiShinya en-aut-sei=Wakatsuki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=UenoAkiko en-aut-sei=Ueno en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NambaTakaomi en-aut-sei=Namba en-aut-mei=Takaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoYorito en-aut-sei=Yamamoto en-aut-mei=Yorito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, 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 Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=diagnostic laparoscopy kn-keyword=diagnostic laparoscopy en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=peritoneal dissemination kn-keyword=peritoneal dissemination en-keyword=lenvatinib kn-keyword=lenvatinib END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=63 end-page=67 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=Metastatic Intraocular Tumor Likely from Hepatocellular Carcinoma Mimicking Panuveitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 77-year-old man undergoing treatment for hepatocellular carcinoma (HCC) presented with blurred vision in his right eye, persisting for 2 months.

This study evaluated changes in these agents’ prescribing patterns and the patient outcomes following the policy shift. We conducted a multicenter retrospective study at four hospitals in Japan’s Okayama and Kagawa prefectures from January 2022 to March 2024. The study period was divided into the public-expenditure phase (January 2022 to September 2023) and the post-expenditure phase (October 2023 to March 2024). We extracted the hospitalized patients’ clinical data from the electronic database. The study’s primary outcome was the antiviral prescription rate; the secondary outcome was in-hospital mortality. Among the 302 hospitalized patients (median age 85 years), 52.0% were classified as having a mild condition. Of the patients with mild conditions, 37.7% were diagnosed in outpatient settings prior to hospitalization. During the public-expenditure phase, 47.4% of the patients received antivirals as outpatients, mainly molnupiravir (80.9%). In the post-expenditure period, 80.0% of the patients were prescribed antivirals, mostly molnupiravir (91.7%). The antiviral prescription rate was significantly higher after the policy change. The overall in-hospital mortality was 15.8%, with no significant difference between the two periods (17.0% vs. 10.5%). Despite the termination of government funding, antiviral prescriptions remained frequent at community hospitals located in highly aging regions of western Japan such as Okayama and Kagawa prefectures. Mortality remains high among the elderly, highlighting the need for continued antiviral therapy and booster vaccinations. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoShohei en-aut-sei=Yamamoto en-aut-mei=Shohei 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=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital 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= en-keyword=coronavirus disease 2019 kn-keyword=coronavirus disease 2019 en-keyword=public expenditure kn-keyword=public expenditure en-keyword=prescribing pattern kn-keyword=prescribing pattern en-keyword=prognosis kn-keyword=prognosis en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=47 end-page=54 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=Time Course of the Development and Loss of Delta-9-tetrahydrocannabinol Tolerance: Effects on Hypothermia and Spontaneous Locomotor Activity in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Deregulation of cannabis use is gradually expanding in Europe and the United States. However, the biological processes driving tolerance to delta-9-tetrahydrocannabinol (Δ9-THC), the main psychoactive component of cannabis, remain unclear. Thus, this study aimed to investigate the mechanisms and time course of tolerance development and loss to Δ9-THC in mice. Male ICR mice (7 weeks old) were administered Δ9-THC once daily for 3 days and then divided into three groups according to the washout period (3-, 10-, and 17-day washout groups). After each washout, changes in body temperature and locomotor activity were measured following re-exposure to Δ9-THC. Furthermore, the mRNA expression levels of CB1 and CB2 receptors in the brain were evaluated using real-time PCR. On day 1, significant hypothermia and reduced spontaneous locomotor activity were observed in the Δ9-THC-treated mice compared with the vehicle-treated mice. Tolerance to the hypothermic and locomotor-suppressing effects of Δ9-THC developed on days 2 and 3, respectively, and dissipated after 3 and 11 days of washout, respectively. These differences in the rates of tolerance development and recovery may reflect distinct underlying mechanisms. No significant changes in receptor mRNA expression were observed. These findings highlight the complexity of Δ9-THC tolerance and its potential implications for long-term cannabis use. en-copyright= kn-copyright= en-aut-name=EguchiYukiomi en-aut-sei=Eguchi en-aut-mei=Yukiomi 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=IrieKeiichi en-aut-sei=Irie en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaYuta en-aut-sei=Yamashita en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EguchiMiyu en-aut-sei=Eguchi en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoTakafumi en-aut-sei=Nakano en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MishimaKenichi en-aut-sei=Mishima en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=2 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=3 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=4 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=5 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=6 en-affil=Department of Oncology and Infectious Disease Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= en-keyword=delta-9-tetrahydrocannabinol kn-keyword=delta-9-tetrahydrocannabinol en-keyword=cannabis kn-keyword=cannabis en-keyword=tolerance kn-keyword=tolerance en-keyword=locomotor kn-keyword=locomotor en-keyword=hypothermic kn-keyword=hypothermic END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=39 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Kinesiophobia Is Associated with Disability, Poor Quality of Life, Psychological Morbidity, and Surgery Dissatisfaction in Patients with Lumbar Microdiscetomy: A Cross-Sectional Controlled Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study aimed to determine the prevalence of kinesiophobia in patients who had undergone lumbar microdiscectomy and to examine its associations with pain intensity, disability, quality of life, depression, anxiety, and satisfaction with surgery. Forty-eight patients with microdiscectomy and 48 healthy controls were enrolled. The Tampa Scale for Kinesiophobia (TSK), Roland-Morris Disability Index (RMDI), Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and Short Form-36 Health Survey (SF-36) were administered to both groups. The scores of TSK, RMDI, HADS-A, and HADS-D were significantly higher and SF-36 scores were significantly lower in the microdiscectomy than the control group (p<0.001 for all). In the microdiscectomy group, median (min-max) RMDI, HADS-A, and HADS-D scores were 19 (4-34), 10 (0-18), and 9 (0-18), respectively, in kinesiophobic patients, and were significantly higher than 6 (2-20), 3 (0-11), 2.5 (0-11) in non-kinesiophobic patients (all p<0.001). The median (min-max) SF-36 PCS, SF-36 MCS, and VAS scores for surgery satisfaction were 36.5 (8.7-75), 52.1 (11-95), 5, 5 (0-10), respectively, in kinesiophobic patients and were significantly lower than 71 (28-95), 85.5 (9-93), 8.5 (3-10) in non-kinesiophobic patients (all p<0.05). TSK scores were significantly correlated with RMDI, HADS-A, HADS-D, SF-36, and surgery satisfaction scores (all p<0.05). Kinesiophobic patients with lumbar microdiscectomy therefore showed greater disability and psychological morbidity, poorer quality of life, and lower satisfaction with surgery. en-copyright= kn-copyright= en-aut-name=TezelNihal en-aut-sei=Tezel en-aut-mei=Nihal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CanAsl?

Global alignment parameters, i.e., the anterior pelvic plane angle (APPa) and proximal femoral shaft angle (PFSa) and other alignment parameters were measured. CA was evaluated based on the patients’ standing coronal radiographs. ΔCA was defined as the difference in CA from 2 weeks before to 1 year after each THA. We classified the cases as stable (S) (CA < 10°; n=63) and pelvic retroversion (R) (CA ? 10°; n=12) groups. Associations between ΔCA and alignment parameters were evaluated by linear regression and a receiver operating characteristic (ROC) analysis. A significant decrease in the PFSa occurred between the 2-week and 1-year post-THA timepoints (7.8±4.3° vs. 4.2±3.6°, p<0.001), with no notable change in other alignment parameters. At 1-year post-THA, the CA of 12 (16%) patients had increased to 4.5±4.4°. Only the preoperative APPa was positively associated with ΔCA (β=0.165, p=0.020). The ROC analysis revealed that the optimal cut-off value for increased CA in the APPa is 2.1° (area under the curve, 0.700; p=0.020; odds ratio, 4.80). The APPa change predicted increased CA, which emphasizes the importance of the use of preoperative standing radiography for identifying the optimal cup positioning for post-THA changes in CA. en-copyright= kn-copyright= en-aut-name=IshibashiKyota en-aut-sei=Ishibashi en-aut-mei=Kyota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OishiHirotaka en-aut-sei=Oishi en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakiRyo en-aut-sei=Araki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawamuraKosuke en-aut-sei=Kawamura en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiIsamu en-aut-sei=Sasaki en-aut-mei=Isamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiEiji en-aut-sei=Sasaki en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamadaHikaru en-aut-sei=Kamada en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KogawaMasakazu en-aut-sei=Kogawa en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaSunao en-aut-sei=Tanaka en-aut-mei=Sunao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NumasawaTakuya en-aut-sei=Numasawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshibashiYasuyuki en-aut-sei=Ishibashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Hirosaki University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Hirosaki University Graduate School of Medicine kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=global alignment kn-keyword=global alignment en-keyword=anterior pelvic plane kn-keyword=anterior pelvic plane en-keyword=cup anteversion kn-keyword=cup anteversion en-keyword=pelvic tilt kn-keyword=pelvic tilt END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=17 end-page=30 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=Development of a Stroke Discharge Support Evaluation Scale for Ward Nurses in Acute Care Hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to develop a scale enabling nurses to objectively evaluate their own stroke discharge support, as a basis for enhancing its overall effectiveness. A draft scale was created based on a literature review, and consisted of a 51-item, 5-point Likert-type questionnaire administered to ward nurses engaged in stroke discharge support at acute care hospitals. Factor analysis was performed to refine the scale. Construct validity was assessed using the known-groups method, and reliability was evaluated through internal consistency analysis. The resulting Stroke Discharge Support Evaluation Scale comprises 29 items across 5 factors, each rated on a 5-point Likert scale. Analysis of the data collected from 237 valid responses demonstrated good internal consistency and supported the scale’s construct validity. The Stroke Discharge Support Evaluation Scale is a reliable and valid tool enabling ward nurses in acute care hospitals to evaluate their own stroke discharge support. en-copyright= kn-copyright= en-aut-name=YanoHideki en-aut-sei=Yano en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaguchiTakeshi en-aut-sei=Yamaguchi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Nursing, Faculty of Human Health Sciences, Niimi University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Nursing, Shikoku University kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=stroke kn-keyword=stroke en-keyword=discharge support kn-keyword=discharge support en-keyword=scale development kn-keyword=scale development END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=9 end-page=16 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=A Novel Nomogram that Predicts Chronic Hemodialysis Patients’ Survival Based on Their Sedentary Behavior en-subtitle= kn-subtitle= en-abstract= kn-abstract=Appropriate treatments for chronic hemodialysis patients are a public health challenge in Japan. Sedentary behavior appears to be closely associated with these patients’ survival. We thus sought to develop a nomogram that predicts survival based on the duration of chronic hemodialysis patients’ sedentary behavior. One hundred twenty-four patients under chronic hemodialysis (73 men, 51 women, age 71.7±11.1 years) were enrolled in this cohort study. The patients wore a triaxial accelerometer that measured both their sedentary behavior, i.e., total sedentary behavior (minutes) and their maximum sedentary bouts (min) on non-hemodialysis days. We obtained the Kaplan-Meier curve and used the log-rank test and a Cox proportional hazards model to evaluate the relationship between the patients’ sedentary behavior and their survival. We also used a Cox proportional hazards model to develop a nomogram for the patients’ 5-year survival rate. Forty-six patients died during the follow-up period. When we stratified the patients by the medians of total sedentary behavior and maximum sedentary bouts, we observed significant between-group differences. After adjustment for confounding factors in a Cox proportional hazards model, total sedentary behavior and maximum sedentary bouts were identified as critical survival factors, and we generated a nomogram using an index of sedentary behavior. Our analysis results demonstrated that sedentary behavior on non-dialysis days was closely associated with the survival of the chronic hemodialysis patients, suggesting that a decrease in sedentary behavior would prolong their survival. The nomogram developed herein based on sedentary behavior may be useful for predicting the outcomes of chronic hemodialysis patients. en-copyright= kn-copyright= en-aut-name=SugaharaKentaro en-aut-sei=Sugahara en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoTakashi en-aut-sei=Kondo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyatakeNobuyuki en-aut-sei=Miyatake en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiHiroyuki en-aut-sei=Nishi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UjikeKazuhiro en-aut-sei=Ujike en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoumotoKiichi en-aut-sei=Koumoto en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NamioKeiichi en-aut-sei=Namio en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HishiiShuhei en-aut-sei=Hishii en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatayamaAkihiko en-aut-sei=Katayama en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuzukiHiromi en-aut-sei=Suzuki en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoYorimasa en-aut-sei=Yamamoto en-aut-mei=Yorimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Innoshima General Hospital kn-affil= affil-num=3 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Innoshima General Hospital kn-affil= affil-num=5 en-affil=Innoshima General Hospital kn-affil= affil-num=6 en-affil=Innoshima General Hospital kn-affil= affil-num=7 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=8 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Faculty of Social Studies, Shikokugakuin University kn-affil= affil-num=10 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=11 en-affil=Innoshima General Hospital kn-affil= en-keyword=nomogram kn-keyword=nomogram en-keyword=chronic hemodialysis kn-keyword=chronic hemodialysis en-keyword=sedentary behavior kn-keyword=sedentary behavior en-keyword=Cox proportional hazards model kn-keyword=Cox proportional hazards model en-keyword=Kaplan- Meier curve kn-keyword=Kaplan- Meier curve END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 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=Usefulness of D-dimer Assay to Confirm the Course of Overt Venous Thromboembolism (VTE) in Cancer Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Venous thromboembolism (VTE) is a serious complication in patients with cancer. In this population, the presence of thrombi is often assessed at cancer diagnosis by measuring D-dimer levels, which have high sensitivity but low specificity for identifying VTE at this clinical time point. However, the usefulness of D-dimer measurement during anticoagulation therapy has not been fully established, despite its widespread use. In this retrospective observational study, we investigated whether D-dimer measurement during anticoagulation therapy in cancer patients could predict overt VTE at follow-up. The study included patients who underwent D-dimer testing and contrast-enhanced computed tomography between 30 and 100 days after initiation of anticoagulation therapy. Eighty-two patients were included: 60 with cancer and 22 without. The diagnostic performance of D-dimer for overt VTE was as follows: sensitivity, 85.7%; specificity, 87.2%; positive predictive value, 78.3%; and negative predictive value, 89.2%. These findings suggest that D-dimer measurement at follow-up has high sensitivity and specificity for overt VTE in cancer patients and may aid in assessing thrombotic status. Clinically, if anticoagulation therapy is continued until D-dimer levels become negative, the absence of overt VTE could be inferred without additional invasive testing. en-copyright= kn-copyright= en-aut-name=YamaokaHidenaru en-aut-sei=Yamaoka en-aut-mei=Hidenaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SarashinaToshihiro en-aut-sei=Sarashina en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MunemasaMitsuru en-aut-sei=Munemasa en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, IMS Tokyo Katsushika General Hospital 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=Seisukai Kuroda Clinic kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=D-dimer kn-keyword=D-dimer en-keyword=venous kn-keyword=venous en-keyword=thromboembolism kn-keyword=thromboembolism en-keyword=cancer kn-keyword=cancer END start-ver=1.4 cd-journal=joma no-vol=153 cd-vols= no-issue=3 article-no= start-page=191 end-page=199 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=Impact of Schizophrenia Spectrum Disorders on the Receipt of Invasive and Systemic Therapy for Colorectal Cancer: A Nationwide Multicenter Retrospective Cohort Study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: This study examined treatment disparities for colorectal cancer among patients diagnosed with schizophrenia spectrum disorders (SSD), focusing on invasive treatments and stage-appropriate systemic therapy within a universal healthcare system.
Method: In this nationwide retrospective cohort study (2018?2021), we identified 248,966 colorectal cancer patients, including 2337 diagnosed with SSD, using linked cancer registry and insurance claims data in Japan. The presence of SSD was classified according to ICD-10 codes F20?29. We used multivariable logistic regression to compare the odds of receiving stage-appropriate adjuvant chemotherapy and systemic therapy, as well as the odds of receiving surgical or endoscopic treatments, between the two groups. The analysis adjusted for age, sex, clinical stage, and scores on the Charlson Comorbidity Index and Barthel Index.
Results: The clinical stage distribution at diagnosis for colorectal cancer differed significantly between patients with SSD and those without psychiatric disorders (p? Conclusion: Patients with SSD encounter substantial disparities in accessing standard colorectal cancer care, particularly systemic therapies. These findings highlight the urgent need for interventions to ensure equitable cancer treatment for this vulnerable population. en-copyright= kn-copyright= en-aut-name=FujiwaraMasaki en-aut-sei=Fujiwara en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaYuto en-aut-sei=Yamada en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiiTaisuke en-aut-sei=Ishii en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeTomone en-aut-sei=Watanabe en-aut-mei=Tomone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimoriMaiko en-aut-sei=Fujimori en-aut-mei=Maiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayaNaoki en-aut-sei=Nakaya en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawamuraToshihiko en-aut-sei=Kawamura en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukiKoji en-aut-sei=Otsuki en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=ShimazuTaichi en-aut-sei=Shimazu en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HinotsuShiro en-aut-sei=Hinotsu en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=UchitomiYosuke en-aut-sei=Uchitomi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=InagakiMasatoshi en-aut-sei=Inagaki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Health Services Research, National Cancer Center Institute for Cancer Control, National Cancer Center kn-affil= affil-num=4 en-affil=Division of Health Services Research, National Cancer Center Institute for Cancer Control, National Cancer Center kn-affil= affil-num=5 en-affil=Division of Survivorship Research, National Cancer Center Institute for Cancer Control, National Cancer Center kn-affil= affil-num=6 en-affil=Tohoku Medical Megabank Organization, Tohoku University kn-affil= affil-num=7 en-affil=Department of Medical Informatics, Shimane University Hospital kn-affil= affil-num=8 en-affil=Department of Psychiatry, Faculty of Medicine, Shimane University kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Medical Development Field, Okayama University kn-affil= affil-num=10 en-affil=Division of Behavioral Sciences, National Cancer Center Institute for Cancer Control, National Cancer Center kn-affil= affil-num=11 en-affil=Department of Biostatistics and Data Management, Sapporo Medical University kn-affil= affil-num=12 en-affil=Department of Cancer Survivorship and Digital Medicine, The Jikei University School of Medicine kn-affil= affil-num=13 en-affil=Department of Psychiatry, Faculty of Medicine, Shimane University kn-affil= en-keyword=colorectal cancer kn-keyword=colorectal cancer en-keyword=healthcare disparities kn-keyword=healthcare disparities en-keyword=psycho-oncology kn-keyword=psycho-oncology en-keyword=schizophrenia spectrum disorders kn-keyword=schizophrenia spectrum disorders END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=e70285 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cardiogenic cerebral infarction after Takotsubo cardiomyopathy in a patient with catatonia: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Takotsubo cardiomyopathy (TTC) is a transient cardiac condition often triggered by an emotional or physical stress. TTC usually has a benign clinical course with full recovery. However, in rare cases, TTC is complicated by cardiogenic shock, left ventricular rupture, or ventricular thrombus. We report a case of a patient with catatonia who developed TTC and subsequently experienced extensive cerebral infarction.
Case Presentation: A 71-year-old woman with no prior psychiatric history was admitted for catatonia following a suicide attempt. During hospitalization, she exhibited electrocardiography (ECG) abnormalities and elevated D-dimer levels. Transthoracic echocardiography revealed apical hypokinesis and basal hyperkinesis, consistent with TTC, along with an intraventricular thrombus. Cardiovascular CT angiography confirmed normal coronary arteries. She was diagnosed with TTC complicated by left ventricular thrombus and deep vein thrombosis. Anticoagulant therapy was initiated. Despite improvement in catatonia with lorazepam, she developed right hemiplegia and aphasia on Day 5 due to cardiogenic cerebral infarction from thromboembolism. Thrombolytic therapy was not indicated, and conservative treatment was provided. Although cardiac function normalized by Day 16, she was left with severe neurological deficits.
Conclusion: The case highlights the diagnostic challenges of TTC in non-communicative psychiatric patients and the potential for severe complications. Psychiatrists need to be aware of the development of TTC as a serious physical complication in patients with catatonia. en-copyright= kn-copyright= en-aut-name=FujiwaraMasaki en-aut-sei=Fujiwara en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaYuto en-aut-sei=Yamada en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoShinji en-aut-sei=Sakamoto en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KodamaMasafumi en-aut-sei=Kodama en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Okayama Psychiatric Medical Center kn-affil= en-keyword=catatonia kn-keyword=catatonia en-keyword=cerebral infarction kn-keyword=cerebral infarction en-keyword=depression kn-keyword=depression en-keyword=Takotsubo cardiomyopathy kn-keyword=Takotsubo cardiomyopathy en-keyword=ventricular thrombus kn-keyword=ventricular thrombus END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=4 article-no= start-page=1422 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative Ozoralizumab Management for Patients with Rheumatoid Arthritis Who Underwent Orthopaedic Surgery: A Retrospective Case Series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Launched in Japan in 2022, ozoralizumab (OZR) is a novel, anti-tumour necrosis factor (TNF)-α inhibitor for treating rheumatoid arthritis (RA) that is refractory to conventional therapies. However, there is a lack of evidence regarding its perioperative management. Methods: This retrospective case series included nine patients with RA who underwent a total of 12 either RA-related (n = 9) or unrelated (n = 3) orthopaedic procedures. We reviewed patient demographics, surgical procedures, perioperative OZR discontinuation periods, and postoperative complications. Results: The mean preoperative OZR discontinuation period was 15.8 days (range, 2?25 days). Sutures were removed at a mean of 12.8 days postoperatively (range, 11?14 days) after adequate wound healing had been confirmed. The mean total discontinuation period was 34.9 days (range, 27?43 days). No cases of surgical site infection (SSI) or delayed wound healing (DWH) were observed during a minimum follow-up period of three months. One patient experienced a disease flare before OZR was restarted. Conclusions: Preoperative OZR discontinuation for up to four weeks appeared to be safe in this cohort. These findings may assist orthopaedic surgeons in determining an appropriate perioperative discontinuation strategy for OZR that minimises SSI and DWH risk while reducing the likelihood of RA flare. en-copyright= kn-copyright= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaRyozo en-aut-sei=Harada en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NatsumedaMasamitsu en-aut-sei=Natsumeda en-aut-mei=Masamitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kurashiki Sweet Hospital kn-affil= affil-num=4 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=6 en-affil=Rheumatic Disease Center, Mabi Memorial Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=delayed wound healing kn-keyword=delayed wound healing en-keyword=discontinuation kn-keyword=discontinuation en-keyword=ozoralizumab kn-keyword=ozoralizumab en-keyword=orthopaedic surgery kn-keyword=orthopaedic surgery en-keyword=perioperative management kn-keyword=perioperative management en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=surgical site infection kn-keyword=surgical site infection END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=9 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=The Influence of Fluidic Flow Stress on the Development of the Secondary Palate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Craniofacial development is orchestrated by a finely regulated interplay of numerous genes and signaling pathways. Palatogenesis proceeds through a complex, stepwise process, in which endogenous mechanical stresses within tissues have been implicated. However, the impact of exogenous fluidic flow mechanical stress derived from maternal movement on palatal development remains unclear. In this study, we investigated the effect of exogenous fluidic flow mechanical stress on palatal morphogenesis, focusing on the horizontal outgrowth of palatal shelves after elevation. Palatal tissues dissected from mouse embryos were subjected to organ culture with or without mechanical loading (loaded and unloaded groups, respectively). Stress magnitude was quantified by calculating wave energy, and morphometric and molecular analyses were performed. Compared with the unloaded group, palatal shelves in the loaded group showed significant increases in thickness and volume, accompanied by enhanced cell proliferation, nuclear translocation of YAP and β-catenin, and upregulation of the osteogenic markers Osterix and Osteocalcin. No significant difference in apoptosis was observed. These findings indicate that exogenous mechanical stress promotes cell proliferation and osteogenic differentiation through the Hippo and WNT/β-catenin pathways in palate explants. Our results suggest that moderate maternal movement-induced mechanical stress contributes to normal palatogenesis, providing new insights into the mechanisms underlying cleft palate. en-copyright= kn-copyright= en-aut-name=NagataMasayo en-aut-sei=Nagata en-aut-mei=Masayo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KosamiTakahiro en-aut-sei=Kosami en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, 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= en-keyword=mechanical stress kn-keyword=mechanical stress en-keyword=palatal development kn-keyword=palatal development en-keyword=β-catenin kn-keyword=β-catenin en-keyword=YAP kn-keyword=YAP END start-ver=1.4 cd-journal=joma no-vol=178 cd-vols= no-issue=1 article-no= start-page=e70775 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=Reactive Carbonyl Species Mediate Isothiocyanate Signaling Pathway in Arabidopsis thaliana Guard Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our previous results demonstrated that depletion of glutathione (GSH) rather than elevation of levels of reactive oxygen species (ROS) is highly correlated with the decrease in stomatal aperture induced by isothiocyanates (ITCs), although ROS is considered a key second messenger in stomatal closure, suggesting that another signal component regulates stomatal apertures along with GSH depletion. This study, using Arabidopsis, clarified that reactive carbonyl species (RCS), especially acrolein and 4-hydroxy-(E)-2-nonenal, are determinants of stomatal aperture responses to ITCs. All tested ITCs, allyl isothiocyanate (AITC), sulforaphane (SFN), benzyl isothiocyanate (BITC), and phenethyl isothiocyanate (PEITC), significantly induced stomatal closure, which was inhibited by the RCS scavengers, carnosine and pyridoxamine. The RCS scavengers suppressed ITC-induced depletion of GSH but not elevation of ROS levels. All tested ITCs (AITC, SFN, BITC, and PEITC) increased levels of RCS and non-RCS aldehydes in the epidermal tissues. However, acrolein, 4-hydroxy-(E)-2-nonenal, crotonaldehyde, and (E)-2-pentenal induced stomatal closure at 10 and 100?μM, whereas propionaldehyde, butyraldehyde, and n-pentanal did not at concentrations up to 100?μM. Acrolein and 4-hydroxy-(E)-2-nonenal more effectively induced stomatal closure and GSH depletion than crotonaldehyde and (E)-2-pentenal did. The contents of RCS were more strongly correlated with GSH levels and stomatal closure than with ROS levels. These results suggest that RCS, especially acrolein and 4-hydroxy-(E)-2-nonenal, acts as key regulators of stomatal closure in guard cells in response to ITCs. en-copyright= kn-copyright= en-aut-name=FarzanaSumaiya en-aut-sei=Farzana en-aut-mei=Sumaiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IslamMd.

Previous studies have shown that oral administration of fermented milk containing lactic acid bacteria (LAB) enhances mucosal APN activity in young mice. This study aimed to investigate whether LAB strains stimulate mucosal APN activity in aged mice and to evaluate its relevance to age-related changes in body composition. The underlying molecular mechanisms were also explored in vitro. Experiment 1: Aged C57BL/6J mice were fed diets supplemented with heat-killed LAB strains?Enterococcus faecalis OU-23 (EF), Leuconostoc mesenteroides OU-03 (LM), or Lactiplantibacillus plantarum SNK12 (LP). Compared to the aged Control group, the ileal APN activity was significantly higher in the LP group. LP administration also elevated serum Gla-osteocalcin levels and decreased serum CTX-1 levels. Experiment 2: IEC-6 cells were co-cultured with LP that had been treated with RNase, DNase, or lysozyme. APN activity was significantly lower in cells co-cultured with DNase- or lysozyme-treated LP compared to those co-cultured with untreated LP. A specific LAB strain may enhance mucosal APN activity in the aged intestine, potentially contributing to improved bone metabolism. This effect may be mediated by bacterial DNA and peptidoglycan. en-copyright= kn-copyright= en-aut-name=TsurutaTakeshi en-aut-sei=Tsuruta en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaMami en-aut-sei=Wakisaka en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeTakumi en-aut-sei=Watanabe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishijimaAoi en-aut-sei=Nishijima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaAkihito en-aut-sei=Ikeda en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeraokaMao en-aut-sei=Teraoka en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=Bio-Lab Co., Ltd. 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= affil-num=6 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=aging kn-keyword=aging en-keyword=aminopeptidase N kn-keyword=aminopeptidase N en-keyword=bone metabolism kn-keyword=bone metabolism en-keyword=lactic acid bacteria kn-keyword=lactic acid bacteria en-keyword=small intestine kn-keyword=small intestine 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=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical efficacy and safety of endoscopic ultrasound-guided ablation therapies for pancreatic neuroendocrine tumors: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pancreatic neuroendocrine tumors (pNETs) are rare; however, they are increasingly being detected. Although surgical resection remains the standard treatment, its invasiveness has prompted interest in less invasive alternatives, particularly for small non-functional pNETs (NF-pNETs) and insulinomas.
Objectives: To evaluate the clinical efficacy and safety of endoscopic ultrasound-guided ethanol injection (EUS-EI) and radiofrequency ablation (EUS-RFA) for pNETs.
Design: A systematic review and meta-analysis.
Data sources and methods: A literature search of PubMed, MEDLINE, and Google Scholar was conducted (April 2005?April 2025). Studies were eligible if they reported clinical outcomes of EUS-EI or EUS-RFA in adult patients with insulinomas or NF-pNETs. The primary endpoints were clinical success (short-term symptom resolution or radiological response) and adverse event (AE) rates. Data were pooled using a random-effects model.
Results: Twenty-six studies were included in the meta-analysis. For insulinomas, the pooled clinical success rate was 77% (95% confidence interval (CI), 59?88) for EUS-EI and 95% (95% CI, 89?97) for EUS-RFA. The pooled incidence of total AEs was 32% (95% CI, 17?51) for EUS-EI and 25% (95% CI, 15?39) for EUS-RFA. For NF-pNETs, the pooled clinical success rates were 76% (95% CI, 54?90) for EUS-EI and 85% (95% CI, 74?92) for EUS-RFA, and the pooled incidence of total AEs was 27% (95% CI, 20?35) and 26% (95% CI, 17?38), respectively. The most common moderate or severe AEs were pancreatitis in 12 patients (7.6%) after EUS-EI, and pancreatic fluid collection in 4 patients (1.9%) and pancreatic duct stricture in 3 patients (1.4%) after EUS-RFA. One fatal case occurred in a 97-year-old patient following EUS-RFA.
Conclusion: Both EUS-EI and EUS-RFA are effective, relatively safe, and minimally invasive treatment options for pNETs. However, severe AE can occur, and careful patient selection and treatment indication are essential.

Among them, Mycobacterium mageritense is a rare, rapidly growing species that can lead to persistent lesions requiring prolonged antimicrobial therapy. Reports of M. mageritense infections involving both the skin and regional lymph nodes are limited, and this case adds new clinical and genomic insights.
Case presentation A 48-year-old previously healthy man presented with a slowly enlarging cutaneous lesion on his lower leg and ipsilateral inguinal lymphadenitis. Empirical antibacterial therapy with β-lactams and macrolides was ineffective. Wound cultures subsequently grew M. mageritense, confirmed by whole-genome sequencing. Several antimicrobial regimens were attempted, and the final successful therapy consisted of oral levofloxacin and minocycline for 4 months, leading to complete clinical resolution. Genomic analysis identified resistance-related genes, including erm(40), aac(2′)-Ib, tet(V), and RbpA, although in vitro minimum inhibitory concentrations showed variable susceptibility. Phylogenetic comparison revealed that the isolate was closely related to previously reported M. mageritense strains from Japan.
Conclusions This case demonstrates that M. mageritense can cause cutaneous infection with secondary lymphadenitis in an immunocompetent host. Accurate species identification using molecular or genomic methods and selection of appropriate combination antibiotic therapy based on susceptibility testing are crucial for successful management of such infections. 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=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuuraYoshiko en-aut-sei=Matsuura en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiharaSatoru en-aut-sei=Sugihara en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MuenrayaPoowadon en-aut-sei=Muenraya en-aut-mei=Poowadon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Bacteriology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Bacteriology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Dermatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Konohana Dermatology Clinic kn-affil= affil-num=5 en-affil=Department of Dermatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Dermatology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Bacteriology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Genome sequence kn-keyword=Genome sequence en-keyword=Lymphadenitis kn-keyword=Lymphadenitis en-keyword=Mycobacterium mageritense kn-keyword=Mycobacterium mageritense en-keyword=Skin and soft tissue infections kn-keyword=Skin and soft tissue infections en-keyword=Rapidly growing mycobacteria kn-keyword=Rapidly growing mycobacteria END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=3 article-no= start-page=369 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of the July 2018 Heavy Rain Disaster on the Endangered Nagoya Daruma Pond Frog (Pelophylax porosus brevipodus) in Rice Fields of Mabi Town, Kurashiki City, Western Japan: Changes in Population Structure over Five Years en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice paddy fields (referred to below as rice fields) are important not only for food production, but also as habitats for various species. The Nagoya Daruma Pond Frog (Pelophylax porosus brevipodus) is an endangered frog species endemic to Japan, mainly living in and around rice field areas. In July 2018, heavy rainfall caused severe flooding in Mabi Town of Okayama Prefecture, western Japan, submerging numerous rice fields and affecting local frog populations, including P. porosus brevipodus. To clarify whether the population structure of P. porosus brevipodus changed following the flood disaster in the rice fields of Mabi Town, we conducted quantitative field surveys in a rice fallow field in mid-October before (2017) and after (2018, 2020?2022, excluding 2019) the flood. The number of frogs declined sharply after the 2018 flood, reaching only a few individuals by 2020, but showed a substantial recovery in 2021 following the resumption of rice cultivation, although numbers decreased again in 2022. This recovery, despite fluctuations, indicates that habitat restoration through rice farming played a key role in enabling the population to rebound. Our findings underscore the importance of maintaining and restoring rice field environments after natural disasters for the survival and long-term recovery of P. porosus brevipodus. en-copyright= kn-copyright= en-aut-name=NakajimaRyo en-aut-sei=Nakajima en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AzumiDaisuke en-aut-sei=Azumi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TadaMasakazu en-aut-sei=Tada en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaichiJunya en-aut-sei=Nakaichi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuharaKoki R. en-aut-sei=Katsuhara en-aut-mei=Koki R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakataKazuyoshi en-aut-sei=Nakata en-aut-mei=Kazuyoshi 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=Okayama Prefectural Public Interest Incorporated Foundation for Environmental Conservation 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=agroecosystem kn-keyword=agroecosystem en-keyword=conservation ecology kn-keyword=conservation ecology en-keyword=endangered amphibian kn-keyword=endangered amphibian en-keyword=paddy field kn-keyword=paddy field en-keyword=post-disaster habitat recovery kn-keyword=post-disaster habitat recovery 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=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SPRED2 suppresses the stemness of hepatocellular carcinoma through the p53/miR-506-3p/KLF4 pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: We previously reported that endogenous Sprouty-related, EVH1 domain-containing protein 2 (SPRED2), an inhibitor of the Ras/Raf/ERK-MAPK pathway, controls hepatocellular carcinoma (HCC) cell stemness by downregulating the expression of pluripotency factors, such as Nanog, c-Myc, and KLF4, in an ERK-dependent fashion. However, the exact mechanisms by which SPRED2 regulates HCC cell stemness have not been established.
Methods: Three human HCC cell lines [HepG2 (parental and SPRED2-deficient), HLE, and Hep3B] were used. Cells were transfected to downregulate or overexpress proteins. Western blot and RT-qPCR were used to evaluate the level of protein and mRNA expression. Co-immunoprecipitation and ChIP-qPCR were used to examine protein-protein interactions and the activation of gene transcription. Clinical HCC tissues were also used to validate in vitro data.
Results: KLF4 was identified as the major pluripotency factor responsible for SPRED2-mediated downregulation of HCC cell stemness and KLF4 expression was regulated by miR-506-3p. SPRED2 formed a protein complex with the tumor suppressor (p53) and upregulated miR-506 gene transcription by binding to the promoter region, resulting in subsequent downregulation of KLF4 mRNA expression. There was a negative correlation between KLF4 expression and miR-506-3p and a positive correlation between miR-506-3p expression and SPRED2 in human HCC samples, highlighting the relevance of the study findings.
Conclusions: The current study revealed a novel SPRED2/p53/miR-506-3p/KLF4 axis through which SPRED2 contributes to the suppression of HCC cell stemness and provides a potential new target to prevent HCC progression. en-copyright= kn-copyright= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoSachio en-aut-sei=Ito en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Moh-Moh-AungAye en-aut-sei=Moh-Moh-Aung en-aut-mei=Aye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangTianyi en-aut-sei=Wang en-aut-mei=Tianyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology and Drug Discovery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=p53 kn-keyword=p53 en-keyword=KLF4 kn-keyword=KLF4 en-keyword=miR-506-3p kn-keyword=miR-506-3p en-keyword=stemness kn-keyword=stemness END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=12 article-no= start-page=e095428 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of education programme to increase competency of health cadres in Indonesia: a cluster non-randomised controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives Health cadres, who assist midwives in supporting pregnant women in community settings, need to enhance their competencies in identifying risk factors and referring high-risk pregnant women to midwives for further care. Since the capabilities of these health cadres are influenced by maternal complications, an educational programme was implemented to strengthen their skills. Therefore, this study aimed to evaluate the competency of health cadres by providing a researcher-developed educational programme.
Design An open-label, cluster non-randomised controlled trial.
Setting and participants Health cadres with at least 1 year of work experience were recruited at six public health centres (PHCs) in Banjarnegara Regency, Indonesia.
Interventions Six PHCs were selected and allocated into intervention group (IG=3 PHCs) and control group (CG=3 PHCs) groups. A total of 133 female health cadres were enrolled across the selected PHCs. At each PHC, a systematic random sampling method was used to select the participants. The researchers and health professionals provided a 3-week period of theoretical and scenario-based simulations to the IG, while the CG received no education.
Outcome measures Researcher-developed questionnaires and checklists were used to assess the knowledge, skills (health assessment, communication, attitude) and confidence. The primary endpoint was competency, a total score of knowledge and skills. The outcome domains were compared between the two groups, and a linear mixed-effect model was used to account for cluster-level variation.
Results A total of 130 (97.7%) completed the study (IG:64, CG:66). The competency score showed significant improvement at endline (CG=49.5?and IG=52.5; p=0.002). The median scores for health assessment skills (CG=12?vs IG=14; p<0.001) and communication skills (CG=7?vs IG=8; p<0.001) were increased in the IG compared with the CG. Mixed-effect model indicated that groups (β (95%?CI) 2.49 (0.57 to 4.41), p=0.012), baseline knowledge (β(95%?CI) 0.73 (0.54 to 0.92), p<0.001) and midline health assessment skills (β (95%?CI) 0.54 (0.25 to 0.82), p<0.001) were significant positive predictors, while age was negatively associated with competency (β (95%?CI) ?0.20 (?0.30 to ?0.10), p<0.001)).
Conclusion Education effectively increased the competency of health cadres. A well-structured education programme is necessary for health cadres to improve and maintain their competencies in monitoring high-risk pregnant women.

Oral and pharyngolaryngeal papillomas are occasionally detected during esophagogastroduodenoscopy. However, their endoscopic features have not been sufficiently investigated.
AIM
To distinguish oral and pharyngolaryngeal papillomas from elevated squamous carcinomas, this study examined their endoscopic features.
METHODS
Forty-seven patients with oral or pharyngeal papilloma participated in this study. The endoscopic characteristics of papillomas were identified by focusing on narrowband and blue laser imaging representations.
RESULTS
Papillomas were classified into three patterns based on their endoscopic features: Salmon roe-like polyps, polyps without capillary transparency, and pinecone-like polyps, with salmon roe-like polyps most prevalent (48.9%). We subsequently analyzed features differentiating papillomas and squamous cell carcinomas in the same region and found that squamous cell carcinomas exhibited at least one of the following three features: Uneven or absent lobulated structure, irregular morphology of capillaries, and coexistence of flat lesions. In contrast, papillomas displayed a uniform lobulated structure, homogeneous or non-visible capillaries, and an absence of flat components. When any of these characteristics were present, two endoscopic specialists evaluated the lesions for the diagnosis of squamous cell carcinoma, with sensitivities of 100% and 97.6% and specificities of 68.9% and 93.3%.
CONCLUSION
Understanding distinct endoscopic patterns of oropharyngeal papillomas and squamous cell carcinomas provides valuable guidance to endoscopists performing esophagogastroduodenoscopy. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=Human papillomavirus kn-keyword=Human papillomavirus en-keyword=Laryngeal polyp kn-keyword=Laryngeal polyp en-keyword=Papilloma kn-keyword=Papilloma en-keyword=Pharyngeal polyp kn-keyword=Pharyngeal polyp END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=1 article-no= start-page=66 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exploratory Analysis for Development Predictive Models of Immune Checkpoint Inhibitor-Induced Myocarditis Using a Nationwide Claims Database en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs), essential in cancer therapy, can cause severe immune-related adverse events (irAEs), including myocarditis with a high fatality rate. Currently, the pathogenesis, biomarkers, and risk factors of ICI-induced myocarditis (ICIM) are not fully understood. This exploratory study aimed to develop machine learning-based models to predict the onset of ICIM within 3 months of starting ICI therapy, using a large health insurance database. The models were constructed using the Light Gradient Boosting Machine (LightGBM) and Random Forest algorithms, incorporating clinical variables such as comorbidities and prior medication classifications. In this study, a strategy combining undersampling and bagging was used to minimize the impact of highly imbalanced datasets. The Random Forest model demonstrated superior performance compared with the LightGBM model, and the SHapley Additive exPlanations (SHAP) analysis for the Random Forest model revealed that the concurrent use of ICIs was the most important variable for predictions. Although predictive performance remains limited (AUROC ? 0.63), this exploratory framework demonstrates the feasibility of developing data-driven risk prediction models for ICIM. Future studies with expanded datasets and integration of laboratory parameters are warranted to improve predictive accuracy and potential clinical applicability. en-copyright= kn-copyright= en-aut-name=YamamotoReina en-aut-sei=Yamamoto en-aut-mei=Reina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagomiKoki en-aut-sei=Nakagomi en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UchiyamaMiyu en-aut-sei=Uchiyama en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MichiharaAyana en-aut-sei=Michihara en-aut-mei=Ayana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiAya F. en-aut-sei=Ozaki en-aut-mei=Aya F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PatelPranav M. en-aut-sei=Patel en-aut-mei=Pranav M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaniokaMaki en-aut-sei=Tanioka en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Pharmacy Practice, School of Pharmacy & Pharmaceutical Sciences, University of California kn-affil= affil-num=7 en-affil=Division of Cardiology, School of Medicine, University of California kn-affil= affil-num=8 en-affil=Medical AI Project, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=machine learning kn-keyword=machine learning en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=myocarditis kn-keyword=myocarditis en-keyword=adverse event kn-keyword=adverse event END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=e101143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic Topical Application (ETA) Therapy for Refractory Overactive Bladder: A First-in-Human Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Refractory overactive bladder (OAB) remains a clinical challenge despite established therapies, such as anticholinergics, β3-agonists, and intradetrusor botulinum toxin (BTX). Emerging evidence suggests that sensory mechanisms within the bladder, including those involving the trigone where superficial afferent networks are present, may contribute to persistent urinary urgency and frequency in some patients. Although intradetrusor BTX injection is effective in selected patients, its impact on these superficial pathways may be limited because the injected drug predominantly distributes within the detrusor. Endoscopic topical application (ETA) therapy delivers BTX directly to the trigone under air cystoscopy, potentially providing targeted modulation of sensory hyperexcitability. We report a 72-year-old woman with long-standing refractory OAB who experienced only partial improvement with repeated intradetrusor BTX injections but achieved clinically meaningful symptom relief after ETA therapy. Nocturia, urgency, urgency urinary incontinence, and voided volume were improved, with no complications other than transient postoperative urethral pain. This case suggests that ETA therapy may represent a promising sensory-focused option for refractory OAB. en-copyright= kn-copyright= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiharaMasahiro en-aut-sei=Sugihara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuiYosuke en-aut-sei=Mitsui en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeToyohiko en-aut-sei=Watanabe en-aut-mei=Toyohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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 Surgery, Nishi Fukuyama Hospital 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= en-keyword=bladder trigone kn-keyword=bladder trigone en-keyword=botulinum toxin kn-keyword=botulinum toxin en-keyword=endoscopic topical application kn-keyword=endoscopic topical application en-keyword=new drug delivery systems kn-keyword=new drug delivery systems en-keyword=refractory overactive bladder kn-keyword=refractory overactive bladder END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue= 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=Addition of human platelet lysate to islet culture medium suppresses islet loss and improves transplantation outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NoguchiHirofumi en-aut-sei=Noguchi en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Miyagi-ShiohiraChika en-aut-sei=Miyagi-Shiohira en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitohIssei en-aut-sei=Saitoh en-aut-mei=Issei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Regenerative Medicine, Graduate School of Medicine, University of the Ryukyus kn-affil= affil-num=2 en-affil=Department of Regenerative Medicine, Graduate School of Medicine, University of the Ryukyus kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatric Dentistry, Asahi University School of Dentistry kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficient resuscitation of early-stage viable but non-culturable cells of Vibrio cholerae using treatment with proteolytic enzymes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio cholerae, the etiological agent of cholera, is ubiquitous in environmental brackish waters. Exposure to low water temperatures induces the bacterium to enter a viable but non-culturable (VBNC) state. In this study, a stepwise decrease in water temperature to 4°C was found to delay the transition to the non-culturable state compared to an abrupt temperature drop, suggesting that V. cholerae cells partially adapt to low temperatures. V. cholerae VBNC cells maintained at 4°C gradually lost their ability to revert to a culturable state. However, VBNC cells in the early stage of dormancy were efficiently resuscitated following treatment with proteolytic enzymes, including proteinase K. The abundance of culturable V. cholerae cells in brackish estuarine waters was quantified using the most probable number (MPN)?quantitative polymerase chain reaction (qPCR) method. Although culturable cells were undetectable in samples treated with bovine serum albumin, they were estimated at 93 and 1,500 MPN/mL in two water samples collected on different days and pre-incubated with proteinase K. Similarly, the abundance of Vibrio species increased markedly following treatment with this enzyme. Additionally, cells of Vibrio species were enumerated by the plating method using CHROMagar Vibrio plates. Consistent with the results of the MPN?qPCR method, treatment with proteinase K resulted in over a 100-fold increase in colony formation. Collectively, these findings suggest that treatment with proteinase K is effective for resuscitating and quantifying V. cholerae VBNC cells in environmental water samples. en-copyright= kn-copyright= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgasawaraMona en-aut-sei=Ogasawara en-aut-mei=Mona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NiwakiShiho en-aut-sei=Niwaki en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiharaRena en-aut-sei=Sugihara en-aut-mei=Rena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=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=Research Institute of Nursing Care for People and Community, University of Hyogo kn-affil= affil-num=6 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae en-keyword=viable but non-culturable kn-keyword=viable but non-culturable en-keyword=VBNC kn-keyword=VBNC en-keyword=protease kn-keyword=protease en-keyword=proteolytic enzyme kn-keyword=proteolytic enzyme END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=FluoNeRF: Fluorescent Novel-View Synthesis Under Novel Light Source Colors and Spectra en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synthesizing photo-realistic images of a scene from arbitrary viewpoints and under arbitrary lighting environments is one of the important research topics in computer vision and graphics. In this paper, we propose a method for synthesizing photo-realistic images of a scene with fluorescent objects from novel viewpoints and under novel lighting colors and spectra. In general, fluorescent materials absorb light with certain wavelengths and then emit light with longer wavelengths than the absorbed ones, in contrast to reflective materials, which preserve wavelengths of light. Therefore, we cannot reproduce the colors of fluorescent objects under arbitrary lighting colors by combining conventional view synthesis techniques with the white balance adjustment of the RGB channels. Accordingly, we extend the novel-view synthesis based on the neural radiance fields by incorporating the superposition principle of light; our proposed method captures a sparse set of images of a scene from varying viewpoints and under varying lighting colors or spectra with active lighting systems such as a color display or a multi-spectral light stage and then synthesizes photo-realistic images of the scene without explicitly modeling its geometric and photometric models. We conducted a number of experiments using real images captured with an LCD and confirmed that our method works better than the existing methods. Moreover, we showed that the extension of our method using more than three primary colors with a light stage enables us to reproduce the colors of fluorescent objects under common light sources. en-copyright= kn-copyright= en-aut-name=ShiLin en-aut-sei=Shi en-aut-mei=Lin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsufujiKengo en-aut-sei=Matsufuji en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaMichitaka en-aut-sei=Yoshida en-aut-mei=Michitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawaharaRyo en-aut-sei=Kawahara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkabeTakahiro en-aut-sei=Okabe en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Artificial Intelligence, Kyushu Institute of Technology kn-affil= affil-num=2 en-affil=Department of Artificial Intelligence, Kyushu Institute of Technology kn-affil= affil-num=3 en-affil=Department of Computer Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Informatics, Kyoto University kn-affil= affil-num=5 en-affil=Department of Computer Science, Okayama University kn-affil= en-keyword=novel-view synthesis kn-keyword=novel-view synthesis en-keyword=neural radiance fields kn-keyword=neural radiance fields en-keyword=relighting kn-keyword=relighting en-keyword=superposition principle kn-keyword=superposition principle en-keyword=fluorescence kn-keyword=fluorescence en-keyword=Stokes shift kn-keyword=Stokes shift END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=11 article-no= start-page=e97931 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative Multidisciplinary Intervention Led to Complete Minimally Invasive Transthoracic Esophagectomy for a Patient With Severe Lung Dysfunction: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Risk factors for postoperative pneumonia after esophagectomy include smoking, severe lung dysfunction, and sarcopenia. Heavy smokers often have chronic obstructive pulmonary disease (COPD), which is associated with poor physical activity and low muscle strength. Sarcopenia is also associated with decreased physical function and malnutrition. These factors lead to a close relationship between COPD and sarcopenia. This report describes the case of a 74-year-old man who presented with dysphagia and was diagnosed with advanced esophageal cancer with lymph node metastasis. Preoperative respiratory function testing showed a forced expiratory volume in one second (FEV1) of 0.76 L because of his past smoking and COPD. Multidisciplinary intervention was started, along with neoadjuvant chemotherapy. Preoperative management improved his physical function. Robot-assisted thoracoscopic subtotal esophagectomy with the patient in the prone position was performed with curative resection and no severe postoperative complications. The perioperative multidisciplinary intervention improved physical functions and enabled safe robot-assisted thoracoscopic esophagectomy for the patient with severe lung dysfunction in the prone position. This case highlights that not only respiratory status but also physical parameters should be taken into account when considering whether a patient can tolerate surgery safely. en-copyright= kn-copyright= en-aut-name=MatsumotoMakoto en-aut-sei=Matsumoto en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KawasakiKento en-aut-sei=Kawasaki en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KunitomoTomoyoshi en-aut-sei=Kunitomo en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=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=copd kn-keyword=copd en-keyword=esophagectomy kn-keyword=esophagectomy en-keyword=perioperative multidisciplinary intervention kn-keyword=perioperative multidisciplinary intervention en-keyword=perioperative rehabilitation kn-keyword=perioperative rehabilitation en-keyword=respiratory function training and rehabilitation kn-keyword=respiratory function training and rehabilitation en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=severe pulmonary dysfunction kn-keyword=severe pulmonary dysfunction END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=e70066 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Procedural Transhiatal Approach for the Thoracic Para‐Aortic Lymph Node: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=The thoracic posterior para-aortic lymph node (TPAN) is classified as an extra-regional lymph node in esophageal cancer, with metastasis indicating poor prognosis. However, some cases with suspected TPAN metastasis may benefit from esophagectomy with lymph node dissection, including TPAN. This report presents the case of a 58-year-old man with upper thoracic esophageal squamous cell carcinoma and suspected simultaneous TPAN metastasis who underwent neoadjuvant chemotherapy followed by thoracoscopic subtotal esophagectomy and procedural transhiatal TPAN dissection. This transhiatal approach provided direct access to the lymph node without additional thoracic incisions, ensuring safe resection in coordination with the assistant and following anatomical landmarks systematically. Pathological examination showed a false-positive TPAN finding, though the patient later developed distant recurrence. Compared with conventional approaches, this transhiatal technique allows for procedural and reproducible lymphadenectomy while minimizing respiratory burden. This case highlights the feasibility of a transhiatal approach for TPAN dissection. en-copyright= kn-copyright= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakedaYasushige en-aut-sei=Takeda en-aut-mei=Yasushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoHijiri en-aut-sei=Matsumoto en-aut-mei=Hijiri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawasakiKento en-aut-sei=Kawasaki en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KunitomoTomoyoshi en-aut-sei=Kunitomo en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=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=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= en-keyword=112aoP kn-keyword=112aoP en-keyword=esophageal cancer kn-keyword=esophageal cancer en-keyword=thoracic posterior para-aortic lymph node kn-keyword=thoracic posterior para-aortic lymph node END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=4 article-no= start-page=74 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Integrated QGIS-Based Evacuation Route Optimization Approach for Disaster Preparedness Against Urban Flood in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Urban inland flooding has become a serious problem in many cities because heavy rain often exceeds the capacity of drainage systems. In Japan, GIS-based evacuation maps are commonly used to support disaster preparedness, but they still have several limitations. In particular, they do not avoid flooded road segments and cannot generate multiple evacuation options at the same time. This study proposes an improved evacuation route method using the free and open-source software QGIS. The method combines flood-depth data with road network processing to remove roads where the predicted water depth is higher than 0.5 m. It also provides several evacuation paths to different shelters at the same time. A case study in Kurashiki City, Okayama Prefecture, demonstrates that about 1.37% of the road network becomes unusable during an inland-flood scenario. Several existing evacuation routes also pass through hazardous areas, but the QGIS-based method avoids these areas in most cases. Since the workflow uses only built-in QGIS functions and does not require programming or plug-ins, it is easy to reproduce and apply in other regions. This study offers a practical and low-cost method to support inland-flood evacuation planning for local governments. en-copyright= kn-copyright= en-aut-name=PanWenliang en-aut-sei=Pan en-aut-mei=Wenliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PanShijun en-aut-sei=Pan en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetoJunko en-aut-sei=Kaneto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaKeisuke en-aut-sei=Yoshida en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaSatoshi en-aut-sei=Nishiyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=evacuation route kn-keyword=evacuation route en-keyword=hazard mapping kn-keyword=hazard mapping en-keyword=inland flood kn-keyword=inland flood en-keyword=land use analysis kn-keyword=land use analysis en-keyword=QGIS kn-keyword=QGIS END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genotype?Phenotype Correlations of Li?Fraumeni Syndrome in Japan Children's Cancer Group LFS20 Study Cohort en-subtitle= kn-subtitle= en-abstract= kn-abstract=Li?Fraumeni syndrome (LFS) is a cancer predisposition syndrome caused by germline pathogenic variants in the TP53 gene. With the increasing use of multi-gene panel testing, TP53 variants have been identified in individuals who do not meet established TP53 testing criteria, such as the Chompret criteria. The term “attenuated LFS” has been proposed for some of these cases, particularly those with adult-onset cancer. We analyzed participants of the Japanese nationwide prospective clinical trial of the cancer surveillance program (Japan Children's Cancer Group LFS-20), along with clinical information including their family histories, to better understand their genotypic and phenotypic characteristics. We identified 32 distinct TP53 variants from 41 families (45 participants), including four missense variants with conflicting classifications of pathogenicity in ClinVar. Among these families, 36 (88%) met the LFS criteria (hereafter referred to as “LFS” in contrast to attenuated LFS), while 5 (12%) were classified as attenuated LFS. Including 30 additional family members carrying the same variant, we analyzed 75 individuals with TP53 variants. Of these, 40 with LFS and 6 with attenuated LFS had cancer. Multiple primary cancers occurred in 22 individuals (21 LFS, 1 attenuated LFS). LFS-core tumors accounted for 66% (58/88) of cancers in the LFS group and 63% (5/8) in the attenuated LFS group; of note, all core tumors in the attenuated group were limited to breast cancer. Hotspot missense variants were detected in 11 of 36 LFS families and in none of 5 attenuated LFS families, and non-hotspot null variants were found in 14 and 1, respectively. Our study revealed genotype?phenotype correlations in several respects.

These trials reported 12-month overall survival (OS) rates of 60%?67% with atezolizumab combination therapy. J-TAIL-2 (NCT04501497), a prospective, multicenter, observational study, evaluated atezolizumab combination therapy in routine clinical practice in Japan. Patients ??20?years old with NSCLC received atezolizumab plus carboplatin and nab-paclitaxel (atezo + CnP), atezolizumab plus carboplatin or cisplatin plus pemetrexed (atezo + PP), or atezolizumab plus bevacizumab plus carboplatin and paclitaxel (atezo + bev?+?CP) in clinical practice. The primary endpoint was the 12-month OS rate. Secondary endpoints included OS, progression-free survival, and subgroup analyses, including IMpower-unlike (did not meet the main eligibility criteria of each IMpower trial) and IMpower-like patients. In total, 814 patients were enrolled (atezo + CnP, n?=?217; atezo + PP, n?=?211; atezo + bev?+?CP, n?=?386). The IMpower-unlike group included patients with Eastern Cooperative Oncology Group performance status ??2, autoimmune disease, or interstitial lung disease. Twelve-month OS rates (95% confidence interval [CI]) were 62.9% (55.8?69.2), 72.1% (65.2?77.9), and 68.3% (63.2?72.9) with atezo + CnP, atezo + PP, and atezo + bev?+?CP, respectively. OS hazard ratios (95% CI) in the IMpower-unlike vs. -like subgroups were 1.36 (0.91?2.05), 1.08 (0.70?1.68), and 1.49 (1.09?2.06), respectively. No new safety signals were observed. Real-world efficacy and safety for each atezolizumab combination were comparable to those in the relevant IMpower trials. en-copyright= kn-copyright= en-aut-name=YoshiokaHiroshige en-aut-sei=Yoshioka

considered an essential component of the blue economy. Because seaweed extracts are rich in bioactive compounds that enhance plant stress resilience, exploiting this resource could offer a sustainable solution for crop production. Salinity is a major abiotic challenge that significantly impacts crop yield and food security. Through meta-analysis, we explored whether the exogenous application of seaweed extracts improves the salt tolerance of cereal crops. All the studies chosen for this study utilized aqueous seaweed extracts as foliar sprays. A multi-level meta-analysis with a mixed effects model was performed to determine the effect size. This meta-analysis demonstrated that applying aqueous seaweed extracts enhanced the shoot and root biomass under normal and salinity stress conditions, suggesting that seaweed extract can help improve crop stress tolerance. The seaweeds studied belonged to three classes: Phaeophyceae, Rhodophyta, and Chlorophyta, with extracts from Chlorophyta and Phaeophyceae significantly enhancing biomass production under salinity conditions. Applying aqueous seaweed extracts effectively improved salinity tolerance at both 34.2?100?mM and 101?400?mM NaCl equivalent salinity stress. Moreover, exogenous foliar application of ??25% aqueous seaweed extracts was most effective for improving salinity tolerance in cereals. The impact of seaweed extracts on cereal crop yields has not been extensively reported; therefore, further studies should focus on this aspect. en-copyright= kn-copyright= en-aut-name=NuruzzamanMd. en-aut-sei=Nuruzzaman en-aut-mei=Md. 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=HannanMd.

Reports indicate that abemaciclib provides benefits regardless of the PIK3CA mutation status; however, its clinical benefits remain insufficient. This study aimed to evaluate the clinical significance of switching CDK4/6i?+?ET in a large real-world cohort. Using a medical database, we identified 13,284 patients with hormone receptor?positive/human epidermal growth factor receptor 2?negative advanced breast cancer who received CDK4/6i?+?ET between 2008 and 2022. Patients were categorized into five groups based on their first- and second-line therapy patterns. We compared the median time to discontinuation (TTD) among the groups. In patients who switched from one CDK4/6i?+?ET to another CDK4/6i?+?ET, the second-line TTD and total TTD of first- and second-line therapies (n?=?542) were significantly longer than those in patients who switched from CDK4/6i?+?ET to ET monotherapy (n?=?490) (the second-line TTD: 11.2 vs. 4.9 months, p? Patients and methods: We carried out a multi-institutional retrospective cohort study in patients with breast cancer who developed HR-positive HER2-negative LRR. Patients who underwent curative surgery for LRR between 2014 and 2018 were categorized based on whether they received adjuvant chemotherapy for LRR (CTx versus no-CTx). Invasive disease-free survival (iDFS) was evaluated between the groups by Cox proportional hazards analysis. The primary analysis used a double-robust Cox model incorporating inverse probability of treatment weighting, and a sensitivity analysis using propensity score matching was also carried out.
Results: A total of 958 patients were included. The median time from the primary surgery to LRR diagnosis was 9.5 years (interquartile range 3.1-10.1 years). There were 235 patients (25%) in the CTx group and 722 (75%) in the no-CTx group. Among all patients, the 5-year iDFS rate was 75.4% [95% confidence interval (CI) 72.4% to 78.2%]. Multivariate analysis showed better iDFS in the CTx group (hazard ratio 0.70, 95% CI 0.49-0.99, P = 0.045). Sensitivity analysis supported these findings. Subgroup analyses showed that the CTx group had better iDFS in cases with non-ipsilateral breast tumor recurrence (IBTR), recurrences during adjuvant endocrine therapy for primary breast cancer, and without perioperative chemotherapy for primary breast cancer. Secondary analysis showed no significant difference with a worse trend toward overall survival in the CTx group with multivariate Cox proportional hazards analysis.
Conclusion: Adjuvant chemotherapy for HR-positive HER2-negative LRR was associated with better iDFS, particularly in cases of non-IBTR, recurrences during adjuvant endocrine therapy, and no prior perioperative chemotherapy for their primary tumor. However, the retrospective design and inability to distinguish true recurrences from new primary tumors in IBTR warrant cautious interpretation. en-copyright= kn-copyright= en-aut-name=OzakiY.

kn-title=Suppression of Na+ Uptake Via Apoplastic Flow by Chitosan in Rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Chitosan enhances tolerance to salinity in rice. Apoplastic flow plays a crucial role in the accumulation of sodium (Na+) in rice under salinity. This study investigated the effects of exogenous chitosan on apoplastic flow and Na+ uptake in NaCl-treated rice seedlings. Methods: We employed an apoplastic tracer, trisodium salt of 8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS), in order to evaluate apoplastic flow in rice (Oryza sativa L., cv. Nipponbare) seedlings that were hydroponically grown in the solution containing NaCl (0 and 25 mM), and chitosan (0 mg L??1, 10 mg L??1, and 50 mg L??1). Results: Application of 25 mM NaCl significantly increased PTS uptake and Na+ content in shoots but did not affect K+ content, resulting in a lower K+/Na+ ratio although 25 mM NaCl did not affect the seedling growth. The application of chitosan suppressed Na+-enhanced PTS uptake and Na+ accumulation in shoots without affecting the K+ content, which led to a higher K+/Na+ ratio. Moreover, chitosan did not affect the reducing sugar content or electrical conductivity in the solution containing NaCl. Conclusions: These results suggest that application of chitosan suppressed Na+-enhanced apoplastic flow to reduce Na+ uptake in rice seedlings. en-copyright= kn-copyright= en-aut-name=ZhaoMaoxiang en-aut-sei=Zhao en-aut-mei=Maoxiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GalibMd.

Therefore, controlling the inflammatory response and ROS production is crucial for human health. Electrical stimulation (ES) has been shown to have antioxidant and anti-inflammatory effects on macrophages. However, the key pathway underlying these effects remains unclear.
Methods: In this study, ES was applied to Lipopolysaccharide (LPS)-stimulated macrophages, and the production of ROS and 8?hydroxy?2′?deoxyguanosine (8-OHdG), inflammatory cytokine expression, and intracellular metabolites were analyzed in a glucose-6-phosphate dehydrogenase (G6PD) knockdown experiment, the rate-limiting enzyme of the Pentose Phosphate Pathway(PPP).
Results: ES significantly increased sedoheptulose 7-phosphate (S7P), an intermediate metabolite in PPP, and reduced ROS and 8-OHdG production and the expression of inflammatory cytokines in LPS-stimulated macrophages. Meanwhile, ES did not exert antioxidant effects in G6PD-knockdown macrophages.
Discussion: These findings indicate that the antioxidant effects of ES are mediated by PPP in LPS-stimulated macrophages. en-copyright= kn-copyright= en-aut-name=UemuraMikiko en-aut-sei=Uemura en-aut-mei=Mikiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaeshigeNoriaki en-aut-sei=Maeshige en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaguchiAtomu en-aut-sei=Yamaguchi en-aut-mei=Atomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaXiaoqi en-aut-sei=Ma en-aut-mei=Xiaoqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FuYunfei en-aut-sei=Fu en-aut-mei=Yunfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InoueTaketo en-aut-sei=Inoue en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsudaMami en-aut-sei=Matsuda en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishimuraYuya en-aut-sei=Nishimura en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HasunumaTomohisa en-aut-sei=Hasunuma en-aut-mei=Tomohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WangJi en-aut-sei=Wang en-aut-mei=Ji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KondoHiroyo en-aut-sei=Kondo en-aut-mei=Hiroyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujinoHidemi en-aut-sei=Fujino en-aut-mei=Hidemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Rehabilitation Science, Kobe University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Rehabilitation Science, Kobe University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Rehabilitation Science, Kobe University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Rehabilitation Science, Kobe University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Rehabilitation Science, Kobe University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Assisted Reproductive Technology Center, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Science, Technology and Innovation, Kobe University kn-affil= affil-num=8 en-affil=Graduate School of Science, Technology and Innovation, Kobe University kn-affil= affil-num=9 en-affil=Graduate School of Science, Technology and Innovation, Kobe University kn-affil= affil-num=10 en-affil=Department of Toxicology and Sanitary Chemistry, School of Public Health, Capital Medical University kn-affil= affil-num=11 en-affil=Department of Nutrition, Faculty of Health and Nutrition, Shubun University kn-affil= affil-num=12 en-affil=Department of Rehabilitation Science, Kobe University Graduate School of Health Sciences kn-affil= en-keyword=microcurrent stimulation kn-keyword=microcurrent stimulation en-keyword=pentose phosphate pathway (PPP) kn-keyword=pentose phosphate pathway (PPP) en-keyword=NADPH kn-keyword=NADPH en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=macrophage kn-keyword=macrophage en-keyword=glucose metabolism kn-keyword=glucose metabolism END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Profiling of Pediatric Solid Tumors With a Dual DNA/RNA Panel: JCCG-TOP2 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=To develop an optimized genomic medicine platform for pediatric cancers, a nationwide cancer genome profiling project was conducted from January 2022 to February 2023 in collaboration with the Japan Children's Cancer Group. This prospective observational study analyzed matched blood and FFPE tumor samples from patients aged 0?29?years with solid tumors. Genomic analysis used the TOP2 hybrid capture?enrichment system, targeting 737 and 455 genes in the DNA and RNA panels, along with allele-specific genome copy number alterations. A total of 210 patients from 50 institutions were enrolled across Japan (median age, 8?years; range, 0?25). Of these, 154 (77%) were enrolled at diagnosis or during/after initial treatment and 56 (27%) at disease progression or relapse. The TOP2 findings had great benefits in clarifying the diagnosis of pediatric solid tumors. Among the 204 patients with genomic results, 147 (72%) had potentially actionable findings, including diagnostic, prognostic, and therapeutic findings in 111 (54%), 61 (30%), and 64 (31%), respectively. Oncogenic fusions were noted in 45 (23%) patients. A copy number alteration was identified in at least one genomic region in 170 (83%) patients. Two patients exhibited a high tumor mutation burden. Seventeen (8%) patients harbored a germline pathogenic/likely pathogenic variant in cancer-predisposing genes. This study highlighted the feasibility of implementing a nationwide precision medicine platform and the clinical utility of the TOP2 system for pediatric cancers. The results support the integration of genomic data into the standard clinical care of pediatric patients with cancer, both at diagnosis and at relapse. en-copyright= kn-copyright=

Streptococcus mutans strains possessing genes encoding collagen-binding proteins in the Japanese population en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Streptococcus mutans harbors collagen-binding protein genes, namely cnm and cbm, which are implicated in its virulence and pathogenicity in both oral and extraoral infections. Although both genes were initially identified in S. mutans isolated from Japanese populations, their geographical prevalence, distribution, and genetic relatedness within Japan remain largely unexplored. This study investigates the prevalence of S. mutans strains carrying cnm and cbm genes across Japan, correlates these findings with clinical data, and analyzes the genetic relatedness of cnm-positive and cnm-negative strains using multilocus sequence typing (MLST).
Methods Dental plaque specimens were collected from 1248 individuals from eight Japanese cities (Hiroshima, Fukuoka, Nagasaki, Niigata, Okayama, Osaka, Tokushima, and Tokyo) and plated on selective medium for S. mutans isolation. S. mutans was confirmed in 523 subjects by colony morphology and PCR using species-specific primers, and the presence of the cnm and cbm genes was determined by PCR with gene-specific primers. Demographic (age, sex) and oral examination (caries prevalence, caries experience, number of teeth) data were recorded. MLST was employed to genotype selected cnm-positive and cnm-negative S. mutans strains to assess their clonal relationships.
Results Among 523 subjects possessing S. mutans (aged 3?90 years), we detected cnm-positive strains in all cities; specifically, the prevalence ranged from 5.5% in Okayama to 25.0% in Tokushima. In contrast, cbm-positive strains were less common and undetectable in some regions. Furthermore, subjects harboring cnm-positive S. mutans were significantly older (p?=?0.002) and had higher caries prevalence and experience (p? Conclusions The cnm-positive S. mutans strains are widely distributed throughout Japan and are associated with increased age and caries burden. Although core genome analysis revealed some clonal patterns, the non-uniform distribution of the non-core cnm gene is likely influenced by horizontal gene transfer, providing S. mutans with adaptive advantages irrespective of its core genetic background or serotype. en-copyright= kn-copyright= en-aut-name=OkudaMakoto en-aut-sei=Okuda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuehiroYuto en-aut-sei=Suehiro en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LapirattanakulJinthana en-aut-sei=Lapirattanakul en-aut-mei=Jinthana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaShuhei en-aut-sei=Naka en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Matsumoto-NakanoMichiyo en-aut-sei=Matsumoto-Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomuraRyota en-aut-sei=Nomura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkawaRena en-aut-sei=Okawa en-aut-mei=Rena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanoKazuhiko en-aut-sei=Nakano en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=3 en-affil=Department of Oral Microbiology, Faculty of Dentistry, Mahidol University kn-affil= affil-num=4 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=7 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=8 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= en-keyword=Collagen-binding protein gene kn-keyword=Collagen-binding protein gene en-keyword=cnm gene kn-keyword=cnm gene en-keyword=cbm gene kn-keyword=cbm gene en-keyword=Japan kn-keyword=Japan en-keyword=Multilocus sequence typing kn-keyword=Multilocus sequence typing en-keyword=Serotype kn-keyword=Serotype en-keyword=Streptococcus mutans kn-keyword=Streptococcus mutans END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=German Chamomile (Matricaria chamomilla) Induces Cytochrome P450 Expression Through Increased BMAL1 Protein Expression in Liver Nuclei en-subtitle= kn-subtitle= en-abstract= kn-abstract=German chamomile (Matricaria chamomilla) is a medicinal herb that promotes improved digestion and reduces insomnia. Although it is widely used worldwide, the mechanism of induction of drug-metabolizing enzymes is unknown. We found that German chamomile extracts induced cytochrome P450 expression at the transcriptional stage. Cyp3a11 expression is decreased at night in wild-type mice, but German chamomile extract induced nocturnal Cyp3a11 and Cyp1a2 expression. German chamomile extract increased the nuclear protein expression of the clock gene BMAL1, which drives and abolishes the rhythm of Cyp3a11 expression. By contrast, German chamomile extract did not significantly alter clock gene expression in the suprachiasmatic nucleus (SCN). Similarly, it did not affect the mRNA expression of the clock genes in the kidneys. Because it did not induce the mRNA expression of ATP-binding cassette (ABC) transporters (Abcb1a, Abcc2, Abcc4, and Abcg2) in the kidney, German chamomile extract had no effect on the transcription of pharmacokinetics-related molecules other than CYPs. German chamomile extract promoted liver-selective nuclear transfer rhythm changes in clock genes and induced the expression of CYPs. This study may help to explain the mechanism of drug interactions associated with chronic German chamomile extract consumption. en-copyright= kn-copyright= en-aut-name=IkedaMoka en-aut-sei=Ikeda en-aut-mei=Moka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsurudomeYuya en-aut-sei=Tsurudome en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnrinMai en-aut-sei=Enrin en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaYukiyo en-aut-sei=Wada en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoriguchiMichiko en-aut-sei=Horiguchi en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UshijimaKentaro en-aut-sei=Ushijima en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=2 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=3 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=4 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=5 en-affil=Department of Regenerative and Therapeutic Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= en-keyword=Circadian clock kn-keyword=Circadian clock en-keyword=German chamomile kn-keyword=German chamomile en-keyword=Xenobiotic transporter kn-keyword=Xenobiotic transporter en-keyword=Metabolic enzyme kn-keyword=Metabolic enzyme en-keyword=Clock gene kn-keyword=Clock gene END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=2 article-no= start-page=e70173 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Maturity-Onset Diabetes of the Young (MODY) With HNF1B p.Glu105Lys Mutation Achieving Significant Insulin Reduction on Tirzepatide: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=This report describes the first case of maturity-onset diabetes in young (MODY) with HNF1B mutation started administration of the dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, tirzepatide. A 26-year-old female with a 15-year history of diabetes mellitus was diagnosed with MODY, which is characterized by decreased insulin secretion. She was treated with tirzepatide, which significantly improved her glycemic management; insulin secretion increased the fasting serum C-peptide immunoreactivity from 0.36 to 1.09?ng/mL. The patient discontinued glimepiride, and her total daily insulin dose was reduced from 88 to 4?units. This report highlights the glucose-lowering effects of tirzepatide in a patient with MODY who has the HNF1B p.Glu105Lys mutation. en-copyright= kn-copyright= en-aut-name=SueMihiro en-aut-sei=Sue en-aut-mei=Mihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueAyumi en-aut-sei=Inoue en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatayamaAkihiro en-aut-sei=Katayama en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeshigawaraSanae en-aut-sei=Teshigawara en-aut-mei=Sanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsushitaYuichi en-aut-sei=Matsushita en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakedaMasaya en-aut-sei=Takeda en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IsedaIzumi en-aut-sei=Iseda en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HidaKazuyuki en-aut-sei=Hida en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=2 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=3 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=7 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=8 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Diabetology and Metabolism, NHO Okayama Medical Center kn-affil= en-keyword=glucagon-like peptide-1 (GLP-1) kn-keyword=glucagon-like peptide-1 (GLP-1) en-keyword=glucose-dependent insulinotropic polypeptide (GIP) kn-keyword=glucose-dependent insulinotropic polypeptide (GIP) en-keyword=maturity-onset diabetes in young (MODY) kn-keyword=maturity-onset diabetes in young (MODY) en-keyword=tirzepatide kn-keyword=tirzepatide END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=2 article-no= start-page=222 end-page=225 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ethical Use of Cadaveric Images in Anatomical Textbooks, Atlases, and Journals: A Consensus Response From Authors and Editors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose. Cadaveric photos and drawings made from dissections of cadavers have been used in anatomy textbooks and atlases for hundreds of years. They are invaluable for anatomy students and clinical/surgical practitioners. The IFAA guidelines should not restrict the use of those older books; to do so would infringe the rights of those seeking knowledge from these resources. As the images in such textbooks and atlases are anonymized and are used for teaching and research, and the donors and their families are informed about this before the donation, we believe no additional consent is needed. It is impossible to separate educational from “commercial” usage entirely in any situation, e.g., publications from publishers and the use of cadavers in medical schools. Therefore, our best efforts to avoid unethical use of cadaveric images by following traditional consent processes are still needed so that more people will reap the benefits from them. As senior textbook/atlas authors/editors from over 10 countries, we believe that using cadaveric images in anatomy textbooks is appropriate, and no additional consent should be necessary. Such usage falls within the good faith of professionals using these invaluable gifts. 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=KimHee‐Jin en-aut-sei=Kim en-aut-mei=Hee‐Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkitaKeiichi en-aut-sei=Akita en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LoganBari M. en-aut-sei=Logan en-aut-mei=Bari M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HutchingsRalph T. en-aut-sei=Hutchings en-aut-mei=Ralph T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OttoneNicol?s en-aut-sei=Ottone en-aut-mei=Nicol?s kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NonakaYoichi en-aut-sei=Nonaka en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AnandMahindra en-aut-sei=Anand en-aut-mei=Mahindra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BurnsDanny en-aut-sei=Burns en-aut-mei=Danny kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SinghVishram en-aut-sei=Singh en-aut-mei=Vishram kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Peris‐CeldaMaria en-aut-sei=Peris‐Celda en-aut-mei=Maria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Martinez‐SorianoFrancisco en-aut-sei=Martinez‐Soriano en-aut-mei=Francisco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ApaydinNihal en-aut-sei=Apaydin en-aut-mei=Nihal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HannaAmgad en-aut-sei=Hanna en-aut-mei=Amgad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshiokaNobutaka en-aut-sei=Yoshioka en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Fernandez‐MirandaJuan en-aut-sei=Fernandez‐Miranda en-aut-mei=Juan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 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=17 ORCID= en-aut-name=ShojaMohammadali M. en-aut-sei=Shoja en-aut-mei=Mohammadali M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=SaremiFarhood en-aut-sei=Saremi en-aut-mei=Farhood kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=ReinaFrancisco en-aut-sei=Reina en-aut-mei=Francisco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=TabiraYoko en-aut-sei=Tabira en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=CarreraAnna en-aut-sei=Carrera en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=SprattJonathan D. en-aut-sei=Spratt en-aut-mei=Jonathan D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=HoS.

In addition to the canonical brain MRI showing leukoencephalopathy with posterior dominance and hyperintensity along the corticospinal tracts, both patients showed symmetric T2 hyperintensity confined to the lateral and dorsal columns of the cervical cord. Given the long disease durations (22 and 51?years), these findings may represent late-emerging or previously overlooked spinal cord involvement and broaden the neuroradiological spectrum of SPG58. en-copyright= kn-copyright= en-aut-name=MitsutakeAkihiko en-aut-sei=Mitsutake en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsakiMasao en-aut-sei=Osaki en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsukawaTakashi en-aut-sei=Matsukawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OsakoMiho en-aut-sei=Osako en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeuchiChisen en-aut-sei=Takeuchi en-aut-mei=Chisen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MitsuiJun en-aut-sei=Mitsui en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KurokawaRyo en-aut-sei=Kurokawa en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriHarushi en-aut-sei=Mori en-aut-mei=Harushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiYuji en-aut-sei=Takahashi en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=GotoJun en-aut-sei=Goto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TsujiShoji en-aut-sei=Tsuji en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TodaTatsushi en-aut-sei=Toda en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=2 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=4 en-affil=Department of Neurology, Tokyo Metropolitan Kita Medical and Rehabilitation Center for the Disabled kn-affil= affil-num=5 en-affil=Department of Neurology, Tokyo Metropolitan Kita Medical and Rehabilitation Center for the Disabled kn-affil= affil-num=6 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Precision Medicine Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=8 en-affil=Department of Radiology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=9 en-affil=Department of Radiology, School of Medicine, Jichi Medical University kn-affil= affil-num=10 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=11 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=12 en-affil=Institute of Medical Genomics, International University of Health and Welfare kn-affil= affil-num=13 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= en-keyword=cerebellar ataxia kn-keyword=cerebellar ataxia en-keyword=hereditary spastic paraplegia kn-keyword=hereditary spastic paraplegia en-keyword=KIF1C kn-keyword=KIF1C en-keyword=leukoencephalopathy kn-keyword=leukoencephalopathy END start-ver=1.4 cd-journal=joma no-vol=493 cd-vols= no-issue= article-no= start-page=110069 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=Coast uplifted by nearby shore-parallel active submarine faults during the 2024 Mw 7.5 Noto Peninsula earthquake en-subtitle= kn-subtitle= en-abstract= kn-abstract=An Mw 7.5 earthquake occurred at 16:10 JST on January 1, 2024 at a depth of 16 km on the Noto Peninsula, central Japan. This earthquake was the second-largest intraplate earthquake recorded in Japan during 120 years of seismic observation, and it caused approximately 100 km of coastal seafloor emergence along the peninsula's northern coast. Herein, we mapped the emergence of this coastal seafloor and measured the uplift along the coast. The movement of the coastline led to the emergence of approximately 4.4 km2 of seafloor, which is continuous and probably the longest in the world. We determined the uplift distribution along the coast using the white remains of a reddish seaweed called Corallina pilulifera. Its upper limit exhibited a distinct horizontal line, effectively representing the uplift amount throughout the peninsula. Two large, uplifted regions were identified, around Cape Saruyama (5.21 m) in the west and Cape Kurasaki (2.70 m) in the north. Although active offshore submarine faults have been extensively researched, the fault traces remain poorly defined because they are primarily interpreted from seismic reflection profiles. We identified the distribution of active submarine faults using anaglyph-type stereoscopic images, confirming the subsurface deformation structure seen through the seismic reflection profiles. The main fault trace is primarily straight and contiguous with the nearby north coast. The uplift amount is greater near the active fault traces on the north side and diminishes sharply with increasing distance from these faults, indicating a southward tilt of surface uplift related to the active submarine faults. en-copyright= kn-copyright= en-aut-name=GotoHideaki en-aut-sei=Goto en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaTomoru en-aut-sei=Yamanaka en-aut-mei=Tomoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakitaTomohiro en-aut-sei=Makita en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwasaYoshiya en-aut-sei=Iwasa en-aut-mei=Yoshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OguraTakuro en-aut-sei=Ogura en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KagoharaKyoko en-aut-sei=Kagohara en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KumaharaYasuhiro en-aut-sei=Kumahara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiYasuhiro en-aut-sei=Suzuki en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AokiTatsuto en-aut-sei=Aoki en-aut-mei=Tatsuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MoriWataru en-aut-sei=Mori en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaranishiKenta en-aut-sei=Haranishi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakataTakashi en-aut-sei=Nakata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Hiroshima University kn-affil= affil-num=2 en-affil=Natural History Museum and Institute Chiba kn-affil= affil-num=3 en-affil=Hiroshima University kn-affil= affil-num=4 en-affil=University of Teacher Education Fukuoka kn-affil= affil-num=5 en-affil=Hyogo University of Teacher Education kn-affil= affil-num=6 en-affil=Yamaguchi University kn-affil= affil-num=7 en-affil=Hiroshima University kn-affil= affil-num=8 en-affil=Nagoya University kn-affil= affil-num=9 en-affil=Okayama University kn-affil= affil-num=10 en-affil=Kanazawa University kn-affil= affil-num=11 en-affil=Hiroshima University kn-affil= affil-num=12 en-affil=Hiroshima University kn-affil= affil-num=13 en-affil=Hiroshima University kn-affil= en-keyword=Active submarine fault kn-keyword=Active submarine fault en-keyword=Tectonic landform kn-keyword=Tectonic landform en-keyword=Coseismic coastal uplift kn-keyword=Coseismic coastal uplift en-keyword=Noto Peninsula kn-keyword=Noto Peninsula en-keyword=Sea of Japan kn-keyword=Sea of Japan END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=469 end-page=474 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ileus Tube-Related Intussusception: A Case Report and Review of 80 Previously Reported Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of ileus tube-related intussusception in an adult. A 56-year-old man with adhesive bowel obstruction was treated with a nasointestinal ileus tube. Although his condition initially improved, persistent abdominal pain led to the diagnosis of intussusception via CT imaging. Manual repositioning of the tube resolved the intussusception without the need for bowel resection. A review of 80 previously reported cases of ileus tube-associated intussusception (total 81 cases, 95 lesions) highlighted the timing of onset, treatment strategies, and precautions. Early detection and diagnosis are crucial to prevent severe complications and preserve bowel function. en-copyright= kn-copyright= en-aut-name=TsujiiTeruyuki en-aut-sei=Tsujii en-aut-mei=Teruyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KimuraYuji en-aut-sei=Kimura en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsubeRyoichi en-aut-sei=Katsube en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwadouHironori en-aut-sei=Iwadou en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FunabikiSadami en-aut-sei=Funabiki en-aut-mei=Sadami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamikawaYasuaki en-aut-sei=Kamikawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsudaTadakazu en-aut-sei=Matsuda en-aut-mei=Tadakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Matsuda Hospital kn-affil= en-keyword=nasointestinal ileus tube kn-keyword=nasointestinal ileus tube en-keyword=intussusception kn-keyword=intussusception en-keyword=small bowel obstruction kn-keyword=small bowel obstruction en-keyword=enterectomy kn-keyword=enterectomy en-keyword=conservative treatment kn-keyword=conservative treatment END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=463 end-page=468 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=MRI Images of a Case of Adenocarcinoma, Human Papillomavirus-Independent, Mesonephric Type, of the Uterine Cervix en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a case of a woman in her 70s who was diagnosed with mesonephric adenocarcinoma of the uterine cervix, following biopsy and surgery. Preoperative MRI revealed a 7-cm, well-defined circumferential cervical mass with left lateral wall predominance, bulging into the uterine cavity and vagina. The lesion showed intermediate signal intensity on T2-weighted images, diffusion restriction, and early contrast enhancement weaker than that of the myometrium, followed by washout on contrast-enhanced imaging. The circumferential growth pattern with the lateral wall predominance and its imaging characteristics may suggest this rare entity be routinely included in the differential diagnosis of cervical cancers. en-copyright= kn-copyright= en-aut-name=AsanoYudai en-aut-sei=Asano en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiharaChika en-aut-sei=Nishihara en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=OkawaNanako en-aut-sei=Okawa en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiharaHanako en-aut-sei=Sugihara en-aut-mei=Hanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IdaNaoyuki en-aut-sei=Ida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, 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 Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=mesonephric adenocarcinoma kn-keyword=mesonephric adenocarcinoma en-keyword=cervical cancer kn-keyword=cervical cancer en-keyword=MRI imaging characteristics kn-keyword=MRI imaging characteristics en-keyword=HPV-independent adenocarcinoma kn-keyword=HPV-independent adenocarcinoma END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=457 end-page=461 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exacerbation of Proteinuria in a Patient with Beh?et’s Disease and IgA Nephropathy Following Colchicine Discontinuation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This case involves a 23-year-old male who was diagnosed with Beh?et’s disease 5 years ago and managed with colchicine. Two months ago, he underwent renal biopsy due to abnormal urinalysis and kidney dysfunction, leading to a diagnosis of IgA nephropathy. He subsequently underwent tonsillectomy followed by glucocorticoid pulse therapy. However, after the tonsillectomy, discontinuing colchicine led to increased proteinuria, despite the glucocorticoid pulse therapy. Upon reintroducing colchicine, urinary protein excretion decreased, achieving incomplete remission. These findings suggest that colchicine may be effective in decreasing proteinuria in patients with Beh?et’s disease complicated by IgA nephropathy. en-copyright= kn-copyright= en-aut-name=AsakawaTomohiko en-aut-sei=Asakawa en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatayamaYu en-aut-sei=Katayama en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakurabuYoshimasa en-aut-sei=Sakurabu en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaKatsuyoshi en-aut-sei=Katayama en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Matsuoka-UchiyamaNatsumi en-aut-sei=Matsuoka-Uchiyama en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiHidemi en-aut-sei=Takeuchi en-aut-mei=Hidemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaKeiko en-aut-sei=Tanaka en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UmebayashiRyoko en-aut-sei=Umebayashi en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakemotoRika en-aut-sei=Takemoto en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Beh?et’s disease kn-keyword=Beh?et’s disease en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=colchicine kn-keyword=colchicine END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=451 end-page=455 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recurrence of FVIII Inhibitor during Surgery in a Patient with Severe Hemophilia A Receiving Emicizumab Prophylaxis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Emicizumab, a bispecific monoclonal antibody, benefits patients with severe hemophilia A.

This case underscores the necessity of anti-idiotype monoclonal antibodies for accurate monitoring. en-copyright= kn-copyright= en-aut-name=HagiharaMoe en-aut-sei=Hagihara en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayashinoKenta en-aut-sei=Hayashino en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KobayashiHiroki en-aut-sei=Kobayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=emicizumab kn-keyword=emicizumab en-keyword=eptacog alfa kn-keyword=eptacog alfa en-keyword=hemophilia A kn-keyword=hemophilia A en-keyword=inhibitor kn-keyword=inhibitor en-keyword=anti-idiotype monoclonal antibodies to emicizumab kn-keyword=anti-idiotype monoclonal antibodies to emicizumab END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=445 end-page=449 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative Team Management Was Beneficially Associated with Prolonged Postoperative Hospital Stays after Long Lower-Abdominal Surgeries en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our hospital began a PERIO program (perioperative patient management by a multi-disciplinary team from multiple departments) in 2016 to improve patient outcomes. We retrospectively analyzed the clinical effects of the PERIO program regarding the postoperative hospital stay (PHS) in the patients aged ? 18 years who underwent long lower-abdominal surgery at our hospital during the period April 2019 to March 2023. We excluded the cases of patients whose general anesthesia use was < 8 h, those for whom another surgery was performed simultaneously at another site, and emergency surgeries. The outcome was prolonged PHS, defined as exceeding the scheduled number of days specified in the patient’s clinical pathway. Among the 480 patients, prolonged PHS was observed for 270 patients (56.3%). In a multivariate logistic regression using advanced age, sex, high-risk general state, surgery requiring colon resection, serious adverse events (SAEs), and PERIO use, the following were associated with prolonged PHS: advance age (odds ratio [OR] 4.91, 95% confidence interval [CI]: 2.68-8.99, p=0.01), surgery requiring colon resection (OR 4.91, 95%CI: 2.68-8.99, p<0.001), SAE (OR 18.7, 95%CI: 7.22-48.2, p<0.001), and PERIO (OR 0.25, 95%CI: 0.13-0.47, p<0.001). The use of the PERIO program was thus beneficially associated with PHS after long lower-abdominal surgery. en-copyright= kn-copyright= en-aut-name=MatsumiJunya en-aut-sei=Matsumi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= en-keyword=hospital stay kn-keyword=hospital stay en-keyword=ERAS kn-keyword=ERAS en-keyword=surgery kn-keyword=surgery en-keyword=cancer kn-keyword=cancer en-keyword=perioperative management kn-keyword=perioperative management END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=437 end-page=444 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Frailty at 1 Month before ICU Admission Poses a Hospital Mortality Risk in Cancer Survivors whose Condition Has Deteriorated due to Medical Factors en-subtitle= kn-subtitle= en-abstract= kn-abstract=The optimal indications for intensive care unit (ICU) treatment for critically ill cancer survivors whose condition has deteriorated due to medical factors are unclear. To test our hypothesis that frailty before deterioration was associated with hospital mortality in this patient population, we retrospective analyzed the cases of the patients admitted to the ICU at the National Cancer Center Hospital, Japan (April 2014-March 2022). We excluded patients who underwent surgery within 28 days or were denied critical care within 24 h or admitted after cardiopulmonary arrest. Their Clinical Frailty Scale (CFS) scores at 1 month before ICU admission (Pre-ICU) were obtained. Frailty was defined as CFS scores ?4 points. We analyzed 298 admissions and observed that the mortality rate at hospital discharge was significantly higher in the frailty group (n=119). A multivariate analysis demonstrated that the following factors were significantly associated with hospital mortality: Pre-ICU frailty (OR 2.00, 95%CI: 1.19-3.36, p=0.009), cancer type (hematological: OR 2.93, 95%CI: 1.42-6.05, p=0.004), and Sequential Organ Failure Assessment score at ICU admission (OR 0.88, 95%CI: 0.82-0.95, p=0.0008). Frailty retrospectively assessed using the CFS at 1 month pre-ICU admission is a risk factor for hospital mortality in these cancer survivors. en-copyright= kn-copyright= en-aut-name=MatsumiJunya en-aut-sei=Matsumi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoTetsufumi en-aut-sei=Sato en-aut-mei=Tetsufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= en-keyword=frailty kn-keyword=frailty en-keyword=cancer survivor kn-keyword=cancer survivor en-keyword=clinical frailty scale kn-keyword=clinical frailty scale en-keyword=cancer kn-keyword=cancer en-keyword=critically ill kn-keyword=critically ill END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=431 end-page=436 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Weekend Admission and In-Hospital Mortality in Adult Patients with Acute Myeloid Leukemia in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of weekend admission on patient mortality has been investigated in several therapeutic areas, including acute myeloid leukemia (AML), but the investigations’ results are controversial. We evaluated the relationship between in-hospital mortality and weekend admission in adult patients with AML in Japan by conducting a retrospective observational study using administrative data from 144 acute care hospitals from which patients were discharged between April 2014 and March 2019. The primary endpoint was in-hospital mortality, compared between weekend and weekday admissions. Among the 1,340 eligible patients, 11% (150) were admitted during a weekend. The in-hospital mortality rates of the patients admitted during weekends and those admitted on a weekday were 28% (42/150) and 17% (204/1190), respectively. After an adjustment for covariates, weekend admission was associated with a significantly higher risk of in-hospital mortality than weekday admission (HR 1.70, 95%CI: 1.20-2.40; p=0.003). However, such an association was not observed in patients treated in a bio-clean room (HR 1.26, 95%CI: 0.65-2.42). Our results demonstrate that for patients with AML, weekend admission was independently associated with a higher risk of death during hospitalization. An appropriate system is necessary for these patients. en-copyright= kn-copyright= en-aut-name=InoueTakahiro en-aut-sei=Inoue en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuwabaraHiroyo en-aut-sei=Kuwabara en-aut-mei=Hiroyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoKoh en-aut-sei=Yamamoto en-aut-mei=Koh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Healthcare Management Research Center, Chiba University Hospital kn-affil= affil-num=2 en-affil=Healthcare Management Research Center, Chiba University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Yokohama City Minato Red Cross Hospital kn-affil= en-keyword=acute leukemia kn-keyword=acute leukemia en-keyword=weekend admission kn-keyword=weekend admission en-keyword=in-hospital mortality kn-keyword=in-hospital mortality en-keyword=bio-clean room kn-keyword=bio-clean room END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=421 end-page=429 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Thoron Inhalation and Cyclosporin A Treatment on Dextran Sulfate Sodium-Induced Oxidative Damage in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon (222Rn; Rn) and thoron (220Rn; Tn) inhalation have been reported to enhance antioxidant activity in various organs. However, the effects of Tn on the colon have not been investigated. This study aimed to clarify the effects of Tn inhalation, alone and in combination with cyclosporin A (CsA), on dextran sulfate sodium (DSS)-induced colitis, and the accompanying oxidative stress, in mice. Male BALB/c mice were subjected to continuous 8-day Tn inhalation (c-Tn, 533±128 Bq/m3) or alternate-day Tn inhalation over the same period (f-Tn, 577±63Bq/m3), followed by treatment with 3% DSS and either CsA or vehicle for 7 days. Although the disease activity index (DAI) decreased significantly by day 2 in the c-Tn group, scores remained significantly higher than those in the f-Tn group. In the c-Tn group, superoxide dismutase and catalase activity in the colon were significantly elevated compared with those in sham controls. Thus, DSS-induced damage was effectively inhibited in the earlier stages by the c-Tn mode of inhalation than by the f-Tn mode. These findings suggest that continuous Tn inhalation more effectively attenuated early colitis symptoms than alternate-day inhalation, potentially through upregulation of antioxidant defenses. Tn and CsA showed no combined effects. en-copyright= kn-copyright= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=thoron kn-keyword=thoron en-keyword=DSS kn-keyword=DSS en-keyword=antioxidant activity kn-keyword=antioxidant activity en-keyword=CsA kn-keyword=CsA en-keyword=colon kn-keyword=colon END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=413 end-page=419 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=COVID-19 and the Risks of Migraine and Headache: A Mendelian Randomization Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Several observational studies suggested that migraine headache attacks were associated with coronavirus disease 2019 (COVID-19). We investigated genetic causal links between COVID-19 phenotypes and the development of headache and migraine, including migraine with aura (MA) and migraine without aura (MO). We conducted a two-sample Mendelian randomization (MR) analysis to estimate the genetic association in European populations. The inverse-variance weighted (IVW) method was used as the main approach in the MR analyses, together with weighted median and MR-Egger methods. We also performed a series of sensitivity tests to assess the robustness of the MR results. The MR results demonstrated that COVID-19 severity, hospitalization, and susceptibility had no causal effect on the risks of headache, migraine, MA, or MO. No horizontal pleiotropy was detected, and the results were robust as supported by the sensitivity analysis findings. Our analyses identified no casual effect of COVID-19 severity, hospitalization, or susceptibility on the risks of headache or migraine in European populations. en-copyright= kn-copyright= en-aut-name=JiangZhiyun en-aut-sei=Jiang en-aut-mei=Zhiyun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=XiYing en-aut-sei=Xi en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Clinical Laboratory, The First Affiliated Hospital of Zhengzhou University kn-affil= affil-num=2 en-affil=Department of Clinical Laboratory, The First Affiliated Hospital of Zhengzhou University kn-affil= en-keyword=headache kn-keyword=headache en-keyword=migraine kn-keyword=migraine en-keyword=Mendelian randomization kn-keyword=Mendelian randomization en-keyword=COVID-19 kn-keyword=COVID-19 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=405 end-page=412 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-World Outcomes of Anti-Vascular Endothelial Growth Factor Therapy for Neovascular Age-Related Macular Degeneration in Patients Aged 85 or Older en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the treatment outcomes of patients aged ?85 years with neovascular age-related macular degeneration (nAMD) who received anti-vascular endothelial growth factor (anti-VEGF) therapy using either treat-and-extend (TAE) or pro re nata (PRN) regimens for 1 year in real-world clinical practice. Eighty-five eyes from 85 patients were included. Among them, types 1, 2, and 3 macular neovascularization and polypoidal choroidal vasculopathy were present in 27.1%, 17.6%, 18.8%, and 36.5%, respectively. TAE and PRN regimens were used in 43.5% and 56.5% of patients, respectively. At baseline, the PRN group was older and had worse best-corrected visual acuity (BCVA), greater central retinal thickness, and more intraretinal fluid than the TAE group. In the TAE group, the mean number of injections was 7.6, BCVA improved significantly, and all retinal fluid rates decreased. In the PRN group, the mean number of injections was 3.9, BCVA remained unchanged, and the rates of macular fibrosis and atrophy increased. No serious adverse events were observed in either group. Anti-VEGF therapy was safe for patients aged ? 85 years with nAMD, and the TAE regimen effectively improved BCVA in this population. BCVA remained unchanged in the PRN-treated patients, with baseline disease severity and/or undertreatment potentially influencing the outcomes. en-copyright= kn-copyright= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Morizane HosokawaMio en-aut-sei=Morizane Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 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=7 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=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anti-vascular endothelial growth factor therapy kn-keyword=anti-vascular endothelial growth factor therapy en-keyword=neovascular age-related macular degeneration kn-keyword=neovascular age-related macular degeneration en-keyword=age kn-keyword=age en-keyword=treat-and-extend kn-keyword=treat-and-extend en-keyword=pro re nata kn-keyword=pro re nata END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=1599114 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of visual spatial frequency on audiovisual interaction: an event-related potential study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spatial frequency is a fundamental characteristic of visual signals that modulates the audiovisual integration behavior, but the neural mechanisms underlying spatial frequency are not well established. In the present study, the high temporal resolution of event-related potentials was used to investigate how visual spatial frequency modulates audiovisual integration. A visual orientation discrimination task was used, and the spatial frequency of visual stimuli was manipulated under three conditions. Results showed that the influence of visual spatial frequency on audiovisual integration is a dynamic process. The earliest audiovisual integration occurred over the left temporal-occipital regions in the early sensory stage (60?90?ms) for high spatial frequency conditions but was absent for low and middle spatial frequency conditions. In addition, audiovisual integration over fronto-central regions was delayed as spatial frequency increased (from 230?260?ms to 260?320?ms). The integration effect was also observed over parietal and occipital regions at 350?380?ms, and its strength gradually decreased at higher spatial frequencies. These discrepancies in the temporal and spatial distributions of audiovisual integration imply that the role of spatial frequency varies between early sensory and late cognitive stages. The findings of this study offer the first neural demonstration that spatial frequency modulates audiovisual integration, thus providing a basis for studying complex multisensory integration, especially in semantic and emotional domains. en-copyright= kn-copyright= en-aut-name=WuFengxia en-aut-sei=Wu en-aut-mei=Fengxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RenYanna en-aut-sei=Ren en-aut-mei=Yanna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaoTengfei en-aut-sei=Hao en-aut-mei=Tengfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangJingjing en-aut-sei=Yang en-aut-mei=Jingjing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuQiong en-aut-sei=Wu en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=WangMeng en-aut-sei=Wang en-aut-mei=Meng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=2 en-affil=Department of Psychology, College of Humanities and Management, Guizhou University of Traditional Chinese Medicine kn-affil= affil-num=3 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=4 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=5 en-affil=Department of Psychology, Suzhou University of Science and Technology kn-affil= affil-num=6 en-affil=Cognitive Neuroscience Laboratory, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= en-keyword=spatial frequency kn-keyword=spatial frequency en-keyword=visual orientation discrimination kn-keyword=visual orientation discrimination en-keyword=audiovisual integration kn-keyword=audiovisual integration en-keyword=early sensory stage kn-keyword=early sensory stage en-keyword=late cognitive stage kn-keyword=late cognitive stage en-keyword=event-related potentials kn-keyword=event-related potentials END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=4 article-no= start-page=375 end-page=378 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Video review by utilizing asynchronous video communication platform en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Video review is widely recognized as an effective method for teaching communication; however, it can increase educators' workload and learners' stress.

Conclusions: While asynchronous online video reviews provided flexibility and greater participation, challenges remain, and further trials and evaluations were deemed necessary. en-copyright= kn-copyright= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsudaEiko en-aut-sei=Mitsuda en-aut-mei=Eiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoYukichika en-aut-sei=Yamamoto en-aut-mei=Yukichika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatoAtsushi en-aut-sei=Kato en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SoshiMano en-aut-sei=Soshi en-aut-mei=Mano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiguchiMasaya en-aut-sei=Higuchi en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HashimotoTadayuki en-aut-sei=Hashimoto en-aut-mei=Tadayuki 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=Kato & Namiki-dori 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=BonBon, Inc kn-affil= affil-num=6 en-affil=Harvard Medical School 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 Emergency Medicine, Brigham and Women's Hospital kn-affil= en-keyword=feedback kn-keyword=feedback en-keyword=general medicine kn-keyword=general medicine en-keyword=video review kn-keyword=video review END start-ver=1.4 cd-journal=joma no-vol=177 cd-vols= no-issue=4 article-no= start-page=e70398 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative Transcriptome Reveals ART1-Dependent Regulatory Pathways for Fe Toxicity Response in Rice Roots en-subtitle= kn-subtitle= en-abstract= kn-abstract=Iron (Fe) is an essential element for plants, but an excess supply can have detrimental effects. Fe toxicity induces complex physiological and genetic responses, and due to this complexity, the knowledge of transcriptional regulatory mechanisms under Fe toxicity is very limited. Previous studies suggested that plant responses to excess Fe involve oxidative stress caused by reactive oxygen species (ROS), which itself causes transcriptional changes. We hypothesized that dissecting these complex responses could lead to the identification of a novel factor and conducted a comparative transcriptome analysis using roots of rice plants exposed to nutrient solutions containing 1 or 5?mM of hydrogen peroxide (a major form of ROS) or 300?mg?L?1 of Fe (as FeSO4). Genes induced by hydrogen peroxide overlapped with 62%, 49%, and 30% of Fe toxicity-upregulated genes at 3?h, 1?day, and 3?days following treatment initiation. Subsequent gene co-expression analyses classified genes into 21 groups with varying responsiveness to ROS and Fe toxicity. Genes in group 15 were specifically upregulated by Fe toxicity and overlapped significantly with aluminum (Al)-inducible genes and target genes of the Zn-finger transcription factor, ART1, which regulates Al response in rice roots. Additional experiments using the art1 knock-out mutant demonstrated that ART1 is crucial for upregulating genes such as STAR2 and FRDL4 in response to Fe toxicity. This study reveals the contribution of ART1-dependent regulatory pathways in rice roots under Fe toxicity. en-copyright= kn-copyright= en-aut-name=UedaYoshiaki en-aut-sei=Ueda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WissuwaMatthias en-aut-sei=Wissuwa en-aut-mei=Matthias kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Crop, Livestock and Environment Division, Japan International Research Center for Agricultural Sciences kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Crop, Livestock and Environment Division, Japan International Research Center for Agricultural Sciences kn-affil= en-keyword=ART1 kn-keyword=ART1 en-keyword=gene co-expression analysis kn-keyword=gene co-expression analysis en-keyword=iron toxicity kn-keyword=iron toxicity en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=rice kn-keyword=rice END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=3 article-no= start-page=e70091 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Autoclaved lightweight aerated concrete suppressed N2O and CO2 emissions from paddy soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Autoclaved lightweight aerated concrete (AAC), a construction waste that is utilized as a soil amendment, can influence terrestrial carbon dioxide (CO2) emissions. Still, no evidence exists regarding its impact on the emission of nitrous oxide (N2O), which has a higher global warming potential. This study examined effects of AAC on CO2 and N2O emissions from paddy soil under compacted and non-compacted conditions, under 60% and 100% water-holding capacity (WHC). Samples were incubated in glass vials (25°C) for 21 days. Emissions of CO2 and N2O were measured on days 0, 1, 3, 7, 14, and 21 using gas chromatography. The results revealed that AAC significantly (p < 0.05) lowered N2O emission rate during the whole period of incubation, while it suppressed CO2 emission rate only at the early stages (?7 days) of incubation. In compacted soil, the emissions of CO2 were significantly lower, while N2O was significantly higher than that in non-compacted soil, showing the influence of soil physical conditions. The emissions of CO2 and N2O were significantly lower at 100% WHC than those at 60% WHC. AAC suppressed both CO2 and N2O emissions under both compaction and WHC levels. The results confirm that AAC supports suppressing terrestrial emission of both CO2 and N2O, indicating that AAC has a potential as a sustainable soil amendment that enhances the climate change resilience. en-copyright= kn-copyright= en-aut-name=RathnayakeNagoda R.

In this study, we discovered that in 2D materials like BiOCl and Bi4NbO8Cl, composed of interleaved [Bi2O2]2+ and Cl- slabs, the trap depth can be controlled by manipulating the slab stacking structure. In BiOCl, oxygen vacancies (VO) create deep electron traps, while chlorine vacancies (VCl) produce shallow traps. The depth is determined by the coordination around anion vacancies: VO forms strong σ bonds with Bi-6p dangling bonds below the conduction band minimum (CBM), while those around Cl are parallel, forming weak π-bonding. The strong re-hybridization makes the trap depth deeper. In Bi4NbO8Cl, VCl also creates shallow traps, but VO does not produce deep traps although Bi-6p orbitals are also forming strong σ bonding. This difference is attributed to the difference of the energy level of CBM. In both cases, the CBM consists of Bi-6p orbitals extending into the Cl layers. However, these orbitals are isolated in BiOCl, but those in Bi4NbO8Cl are bonded with each other between neighboring [Bi2O2]2+ layers. This unique bonding-based CBM prevents the formation of deep electron traps, and significantly enhances H2 evolution activity by prolonging the lifetime of highly reactive free electrons. en-copyright= kn-copyright= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaTakafumi en-aut-sei=Ogawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaKanta en-aut-sei=Ogawa en-aut-mei=Kanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaMakoto en-aut-sei=Ogawa en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoDaichi en-aut-sei=Kato en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhongChengchao en-aut-sei=Zhong en-aut-mei=Chengchao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KuwabaraAkihide en-aut-sei=Kuwabara en-aut-mei=Akihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeRyu en-aut-sei=Abe en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KageyamaHiroshi en-aut-sei=Kageyama en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Nanostructures Research Laboratory, Japan Fine Ceramics Center kn-affil= affil-num=4 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=5 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=6 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=7 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Nanostructures Research Laboratory, Japan Fine Ceramics Center kn-affil= affil-num=9 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=10 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= en-keyword=photocatalysis kn-keyword=photocatalysis en-keyword=defects kn-keyword=defects en-keyword=charge trapping kn-keyword=charge trapping en-keyword=recombination kn-keyword=recombination en-keyword=time-resolved spectroscopy kn-keyword=time-resolved spectroscopy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced Charge-Transfer Kinetics Enabled by ZrO2?Based Dielectric Layers in Lithium-Ion Batteries en-subtitle= kn-subtitle= en-abstract= kn-abstract=The development of high-rate capability lithium-ion batteries (LIBs) requires suppression of charge-transfer resistance (RCT) at electrode?electrolyte interfaces. Here, zirconia-based dielectric oxides (MZ; M = Y, Gd, Sm, Er, etc.) were introduced onto LiCoO2 (LCO) surfaces as electronically and ionically insulating modifiers to accelerate interfacial ion transport. Electrochemical impedance spectroscopy showed that Y2O3 modified ZrO2 (YZ) decoration reduced RCT from 75.8 Ω in reference LCO to 38.3 Ω, accompanied by a 2.3-fold improvement in capacity retention at 20C. Density functional theory molecular dynamics (DFT?MD) simulations showed that solvated Li ions coordinate with surface oxygen atoms in discharging, and that adsorption energies are governed by local charge distributions determined by stabilizing cations. Optimal adsorption activity, and thus the lowest RCT, occurred when the surface charge corrugation was balanced. These findings provide design principles for dielectric interface engineering to enhance rate capability of LIBs. en-copyright= kn-copyright= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HigakiYusuke en-aut-sei=Higaki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImamuraTomonori en-aut-sei=Imamura en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoribeMotoki en-aut-sei=Horibe en-aut-mei=Motoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoShinya en-aut-sei=Kondo en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasaokaChinatsu en-aut-sei=Sasaoka en-aut-mei=Chinatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirabaruHikaru en-aut-sei=Hirabaru en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaShingo en-aut-sei=Katayama en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakayamaMasanobu en-aut-sei=Nakayama en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Advanced Ceramics, Nagoya Institute of Technology kn-affil= affil-num=5 en-affil=Department of Energy Engineering, Nagoya University kn-affil= affil-num=6 en-affil=R&D Laboratory, Nippon Denko Co., Ltd. kn-affil= affil-num=7 en-affil=R&D Laboratory, Nippon Denko Co., Ltd. kn-affil= affil-num=8 en-affil=R&D Laboratory, Nippon Denko Co., Ltd. kn-affil= affil-num=9 en-affil=Department of Advanced Ceramics, Nagoya Institute of Technology kn-affil= affil-num=10 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=lithium ion battery kn-keyword=lithium ion battery en-keyword=high rate capability kn-keyword=high rate capability en-keyword=charge transfer kn-keyword=charge transfer en-keyword=Li adsorption kn-keyword=Li adsorption en-keyword=dielectric interface kn-keyword=dielectric interface en-keyword=stabilized ZrO2 kn-keyword=stabilized ZrO2 END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=4 article-no= start-page=116 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Drip Fertigation in Greenhouse Eggplant Cultivation: Reducing N2O Emissions and Nitrate Leaching en-subtitle= kn-subtitle= en-abstract= kn-abstract=Drip fertigation (DF) is a sustainable agricultural management technique that optimizes water and nutrient usage, enhances crop productivity, and reduces environmental impact. Herein, we compared the effects of DF and conventional fertilization (CF) with a basal fertilizer on yield, soil inorganic nitrogen dynamics, N2O emissions, and nitrogen leaching during facility-grown eggplant cultivation. The experiment was conducted in a greenhouse from September 2023 to May 2024, with treatments arranged in three rows and three replicates. Soil, gas, and water samples were collected and analyzed throughout the growing season. The results revealed that the DF treatment produced yields comparable to those obtained with the CF treatment while significantly reducing nitrogen and phosphorus inputs. DF effectively prevented excessive nitrogen accumulation in the soil and reduced nitrogen loss through leaching and gas emissions. N2O emissions were significantly lower by more than 60% under DF than under CF. Precise nutrient management in DF suppressed nitrification and denitrification processes, mitigating N2O emissions. DF also significantly reduced nitrogen leaching by more than 70% compared with that in CF. These findings demonstrate that DF effectively enhances agricultural sustainability by improving nutrient use efficiency, reducing greenhouse gas emissions, and minimizing nitrogen leaching during the cultivation of facility-grown eggplant. en-copyright= kn-copyright= en-aut-name=ShiraishiWataru en-aut-sei=Shiraishi en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraShion en-aut-sei=Nishimura en-aut-mei=Shion kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UenoHideto en-aut-sei=Ueno en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Kochi Prefectural Agricultural Research Center kn-affil= affil-num=2 en-affil=Department of Bioresource Production Science, United Graduate School of Agriculture, Ehime University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Bioresource Production Science, United Graduate School of Agriculture, Ehime University kn-affil= en-keyword=drip fertigation kn-keyword=drip fertigation en-keyword=eggplant kn-keyword=eggplant en-keyword=greenhouse cultivation kn-keyword=greenhouse cultivation en-keyword=nitrogen leaching kn-keyword=nitrogen leaching en-keyword=nitrogen use efficiency kn-keyword=nitrogen use efficiency en-keyword=nitrous oxide emissions kn-keyword=nitrous oxide emissions END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=8786 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficient and stable n-type sulfide overall water splitting with separated hydrogen production en-subtitle= kn-subtitle= en-abstract= kn-abstract=N-type sulfide semiconductors are promising photocatalysts due to their broad visible-light absorption, facile synthesis and chemical diversity. However, photocorrosion and limited electron transport in one-step excitation and solid-state Z-scheme systems hinder efficient overall water splitting. Liquid-phase Z-schemes offer a viable alternative, but sluggish mediator kinetics and interfacial side reactions impede their construction. Here we report a stable Z-scheme system integrating n-type CdS and BiVO? with a [Fe(CN)?]??/[Fe(CN)?]?? mediator, achieving 10.2% apparent quantum yield at 450?nm with stoichiometric H?/O? evolution. High activity reflects synergies between Pt@CrOx and Co3O4 cocatalysts on CdS, and cobalt-directed facet asymmetry in BiVO?, resulting in matched kinetics for hydrogen and oxygen evolution in a reversible mediator solution. Stability is dramatically improved through coating CdS and BiVO4 with different oxides to inhibit Fe4[Fe(CN)6]3 precipitation and deactivation by a hitherto unrecognized mechanism. Separate hydrogen and oxygen production is also demonstrated in a two-compartment reactor under visible light and ambient conditions. This work unlocks the long-sought potential of n-type sulfides for efficient, durable and safe solar-driven hydrogen production. en-copyright= kn-copyright= en-aut-name=LuoHaolin en-aut-sei=Luo en-aut-mei=Haolin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuZhixi en-aut-sei=Liu en-aut-mei=Zhixi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LvHaifeng en-aut-sei=Lv en-aut-mei=Haifeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=VequizoJunie Jhon M. en-aut-sei=Vequizo en-aut-mei=Junie Jhon M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhengMengting en-aut-sei=Zheng en-aut-mei=Mengting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HanFeng en-aut-sei=Han en-aut-mei=Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YeZhen en-aut-sei=Ye en-aut-mei=Zhen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShangguanWenfeng en-aut-sei=Shangguan en-aut-mei=Wenfeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LeeAdam F. en-aut-sei=Lee en-aut-mei=Adam F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WuXiaojun en-aut-sei=Wu en-aut-mei=Xiaojun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KazunariDomen en-aut-sei=Kazunari en-aut-mei=Domen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=LuJun en-aut-sei=Lu en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=JiangZhi en-aut-sei=Jiang en-aut-mei=Zhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University kn-affil= affil-num=2 en-affil=Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University kn-affil= affil-num=3 en-affil=State Key Laboratory of Precision and Intelligent Chemistry, School of Chemistry and Material Sciences, and Collaborative Innovation Center of Chemistry for Energy Materials (iChEM), University of Science and Technology of China kn-affil= affil-num=4 en-affil=Institute of Aqua Regeneration, Shinshu University kn-affil= affil-num=5 en-affil=College of Chemical and Biological Engineering, Zhejiang University kn-affil= affil-num=6 en-affil=Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University kn-affil= affil-num=7 en-affil=Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University kn-affil= affil-num=8 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University kn-affil= affil-num=10 en-affil=Centre for Catalysis and Clean Energy, School of Environment and Science, Griffith University kn-affil= affil-num=11 en-affil=State Key Laboratory of Precision and Intelligent Chemistry, School of Chemistry and Material Sciences, and Collaborative Innovation Center of Chemistry for Energy Materials (iChEM), University of Science and Technology of China kn-affil= affil-num=12 en-affil=Institute of Aqua Regeneration, Shinshu University kn-affil= affil-num=13 en-affil=College of Chemical and Biological Engineering, Zhejiang University kn-affil= affil-num=14 en-affil=Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=1714 end-page=1722 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Osmotic pressure‐induced calcium response states en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osmotic pressure is essential for maintaining cellular homeostasis; however, the mechanisms by which cells sense and respond to acute osmotic stress remain incompletely understood. Here, we applied rapid osmotic pressure stimulation to cultured HEK293T cells and observed dynamic intracellular calcium responses. Acute hypotonic stimulation evoked calcium response patterns, whereas hypertonic and isotonic stress did not elicit similar effects. Mechanistically, these calcium signals originated from the endoplasmic reticulum via ryanodine receptor 2 and propagated to neighboring cells through Connexin 43-mediated gap junctions. These findings reveal a previously unrecognized role for calcium signaling in the acute cellular response to osmotic stress, providing new insights into the mechanisms of intercellular communication during osmotic adaptation. en-copyright= kn-copyright= en-aut-name=GaoZidan en-aut-sei=Gao en-aut-mei=Zidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuMasatoshi en-aut-sei=Morimatsu en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Okayama Japan kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Okayama Japan kn-affil= en-keyword=calcium wave kn-keyword=calcium wave en-keyword=Connexin 43 kn-keyword=Connexin 43 en-keyword=hypotonic pressure kn-keyword=hypotonic pressure en-keyword=osmotic pressure kn-keyword=osmotic pressure en-keyword=ryanodine receptor kn-keyword=ryanodine receptor END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=12 article-no= start-page=577 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of miR-128-3p on Renal Inflammation in a Rat Periodontitis Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: The study aim was to investigate the effects of extracellular vesicles (EVs) derived miR-128-3p on renal inflammation using a rat periodontitis model. Methods: Ten-week-old male Wistar rats were divided into two groups: a control (n = 8) and a lipopolysaccharides (LPS) group (n = 8). The LPS group received LPS (Porphyromonas gingivalis) injection in the gingiva for 7 days. At the end of the experiment, plasma, gingival tissue, and kidney samples were collected. Hematoxylin and eosin staining was performed to evaluate the glomerular tissue injury score. Bioinformatic analysis was conducted to identify potential target genes of miR-128-3p. The reverse transcription-quantitative polymerase chain reaction was performed to evaluate miR-128-3p, inflammatory, pro-inflammatory cytokine, chemokine and predicting gene’s expression. The control and LPS groups were compared using Welch’s t-test. p-values < 0.05 were considered to indicate statistical significance. Results: The kidney glomerular tissue injury score was significantly higher in the LPS than in the control group. miR-128-3p expression in the LPS group was significantly higher in the gingival tissue and plasma. mRNAs (interleukin [IL]-1β, tumor necrosis factor [TNF]-α, C-X3-C motif chemokine ligand 1 [CX3CL1], and C-X-C motif chemokine ligand 7 [CXCL7]) expression was higher in the kidney of the LPS group. The potential target genes of activin A receptor type I (Acvr1), ribosomal protein S6 kinase B1 (Rps6kb1), and transforming growth factor beta receptor type 1 (Tgfbr1) were significantly lower in the kidneys of the LPS group. Conclusions: EVs-derived miR-128-3p in LPS induced periodontitis may cause kidney inflammation which may be mediated by, Rps6kb1, Tgfbr1, and Acvr1. en-copyright= kn-copyright= en-aut-name=NurhamimMohammad en-aut-sei=Nurhamim en-aut-mei=Mohammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhangYixuan en-aut-sei=Zhang en-aut-mei=Yixuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaharaMomoko en-aut-sei=Nakahara en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukuharaDaiki en-aut-sei=Fukuhara en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagashimaYosei en-aut-sei=Nagashima en-aut-mei=Yosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Health, Takarazuka University of Medical and Health Care kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=extracellular vesicles kn-keyword=extracellular vesicles en-keyword=miR-128-3p kn-keyword=miR-128-3p en-keyword=mRNA kn-keyword=mRNA en-keyword=inflammation kn-keyword=inflammation en-keyword=periodontitis kn-keyword=periodontitis en-keyword=renal inflammation kn-keyword=renal inflammation en-keyword=lipopolysaccharide kn-keyword=lipopolysaccharide END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=e70144 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese Multi‐Institution Study of Success Rates of Wire‐Guided Biliary Cannulation During Endoscopic Retrograde Cholangiopancreatography in Relation to Guidewire tip Length (JMIT Study) (With Video) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Wire-guided cannulation (WGC) reportedly increases the successful biliary cannulation rate and reduces the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis. Currently, various types of guidewires are available. However, the effect of the length of flexible-tip guidewires on the success rate of biliary cannulation under WGC and the rate of adverse events, especially post-endoscopic retrograde cholangiopancreatography pancreatitis, is unclear. The aim of this study was to compare the influence of long-tapered and short-tapered tips of a 0.025-inch guidewire on outcomes in primary selective biliary cannulation.
Methods: Consecutive patients who underwent biliary access under endoscopic retrograde cholangiopancreatography guidance using WGC at 27 high-volume centers in Japan were enrolled in this prospective registration study. The primary outcome was the technical success rate of biliary cannulation. The secondary outcomes were the rates of adverse events, biliary cannulation time, and number of guidewire insertions into the pancreatic duct.
Results: A total of 530 patients underwent biliary cannulation for biliary disease with native papilla between April 2021 and December 2023. The technical success rate of biliary cannulation was 86.1% (161/187) in the long-tip group and 84.3% (289/343) in the short-tip group, indicating no significant differences between the two groups. Although the frequency of post-endoscopic retrograde cholangiopancreatography was not significantly different, the successful biliary cannulation rate without guidewire mis-insertion into the main pancreatic duct was significantly higher in the long tip group (64.7%, 121/187) compared with the short tip group (54.2%, 186/343p = 0.02).
Conclusions: In conclusion, WGC using long-tip guidewires might reduce the risk of guidewire insertion into the main pancreatic duct. en-copyright= kn-copyright= en-aut-name=OguraTakeshi

kn-title=Amivantamab Plus Lazertinib in Atypical EGFR-Mutated Advanced Non?Small Cell Lung Cancer: Results From CHRYSALIS-2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose For patients with advanced non?small cell lung cancer (NSCLC) harboring atypical epidermal growth factor receptor (EGFR) mutations (eg, S768I, L861Q, G719X), efficacy of current treatment options is limited.
Patients and Methods CHRYSALIS-2 Cohort C enrolled participants with NSCLC harboring atypical EGFR mutations (G719X, S768I, L861Q, etc) and ?2 previous lines of therapy. Participants were treatment-na?ve or previously received first- or second-generation EGFR tyrosine kinase inhibitors. Coexisting exon 20 insertions, exon 19 deletions, or exon 21 L858R mutations were exclusionary. Participants received 1,050 mg (1,400 mg if ?80 kg) intravenous amivantamab once weekly for the first 4 weeks and then once every 2 weeks plus 240 mg oral lazertinib once daily. The primary end point was investigator-assessed objective response rate (ORR).
Results As of January 12, 2024, 105 participants received amivantamab-lazertinib. Most common atypical mutations were G719X (56%), L861X (26%), and S768I (23%), including single and compound mutations. In the overall population (median follow-up: 16.1 months), the ORR was 52% (95% CI, 42 to 62). The median duration of response (mDoR) was 14.1 months (95% CI, 9.5 to 26.2). The median progression-free survival (mPFS) was 11.1 months (95% CI, 7.8 to 17.8); median overall survival (mOS) was not estimable (NE; 95% CI, 22.8 to NE). Adverse events were consistent with previous studies and primarily grade 1 and 2. Among treatment-na?ve participants, the ORR was 57% (95% CI, 42 to 71). The mPFS was 19.5 months (95% CI, 11.2 to NE), the mDoR was 20.7 months (95% CI, 9.9 to NE), and mOS was NE (95% CI, 26.3 to NE). Solitary or compound EGFR mutations had no major impact on ORR. The ORR in participants with P-loop and αC-helix compressing, classical-like, and T790M-like mutations was 45% (n = 38), 64% (n = 14), and 67% (n = 3), respectively.
Conclusion In participants with atypical EGFR-mutated advanced NSCLC, amivantamab-lazertinib demonstrated clinically meaningful antitumor activity with no new safety signals. en-copyright= kn-copyright= en-aut-name=TomasiniPascale en-aut-sei=Tomasini en-aut-mei=Pascale kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangYongsheng en-aut-sei=Wang en-aut-mei=Yongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiYongsheng en-aut-sei=Li en-aut-mei=Yongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FelipEnriqueta en-aut-sei=Felip en-aut-mei=Enriqueta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuLin en-aut-sei=Wu en-aut-mei=Lin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=CuiJiuwei en-aut-sei=Cui en-aut-mei=Jiuwei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BesseBenjamin en-aut-sei=Besse en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SpiraAlexander I. en-aut-sei=Spira en-aut-mei=Alexander I. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NealJoel W. en-aut-sei=Neal en-aut-mei=Joel W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=GotoKoichi en-aut-sei=Goto en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BaikChristina S. en-aut-sei=Baik en-aut-mei=Christina S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MarmarelisMelina E. en-aut-sei=Marmarelis en-aut-mei=Melina E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= en-aut-name=ZhangYiping en-aut-sei=Zhang en-aut-mei=Yiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=LeeJong-Seok en-aut-sei=Lee en-aut-mei=Jong-Seok kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=LeeSe-Hoon en-aut-sei=Lee en-aut-mei=Se-Hoon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=YangJames Chih-Hsin en-aut-sei=Yang en-aut-mei=James Chih-Hsin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=MichelsSebastian en-aut-sei=Michels en-aut-mei=Sebastian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=AnastasiouZacharias en-aut-sei=Anastasiou en-aut-mei=Zacharias kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=CurtinJoshua C. en-aut-sei=Curtin en-aut-mei=Joshua C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=LyuXuesong en-aut-sei=Lyu en-aut-mei=Xuesong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=MahoneyJanine en-aut-sei=Mahoney en-aut-mei=Janine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=DemirdjianLevon en-aut-sei=Demirdjian en-aut-mei=Levon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=MeyerCraig S. en-aut-sei=Meyer en-aut-mei=Craig S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=24 ORCID= en-aut-name=ZhangYouyi en-aut-sei=Zhang en-aut-mei=Youyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=25 ORCID= en-aut-name=LeconteIsabelle en-aut-sei=Leconte en-aut-mei=Isabelle kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=26 ORCID= en-aut-name=LorenziniPatricia en-aut-sei=Lorenzini en-aut-mei=Patricia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=27 ORCID= en-aut-name=KnoblauchRoland E. en-aut-sei=Knoblauch en-aut-mei=Roland E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=28 ORCID= en-aut-name=TraniLeonardo en-aut-sei=Trani en-aut-mei=Leonardo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=29 ORCID= en-aut-name=BaigMahadi en-aut-sei=Baig en-aut-mei=Mahadi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=30 ORCID= en-aut-name=BaumlJoshua M. en-aut-sei=Bauml en-aut-mei=Joshua M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=31 ORCID= en-aut-name=ChoByoung Chul en-aut-sei=Cho en-aut-mei=Byoung Chul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=32 ORCID= affil-num=1 en-affil=Aix Marseille University - CNRS, INSERM, CRCM;

Methods: CHRYSALIS-2 cohort A evaluated amivantamab plus lazertinib in patients with EGFR exon 19 deletion- or L858R-mutated NSCLC with disease progression on or after osimertinib and platinum-based chemotherapy. Primary end point was investigator-assessed objective response rate (ORR). The patients received 1050 mg of intravenous amivantamab (1400 mg if ? 80 kg) plus 240 mg of oral lazertinib.
Results: In cohort A (N = 162), the investigator-assessed ORR was 28% (95% confidence interval [CI]: 22?36). The blinded independent central review?assessed ORR was 35% (95% CI: 27?42), with a median duration of response of 8.3 months (95% CI: 6.7?10.9) and a clinical benefit rate of 58% (95% CI: 50?66). At a median follow-up of 12 months, 32 of 56 responders (57%) achieved a duration of response of more than or equal to 6 months. Median progression-free survival by blinded independent central review was 4.5 months (95% CI: 4.1?5.8); median overall survival was 14.8 months (95% CI: 12.2?18.0). Preliminary evidence of central nervous system antitumor activity was reported in seven patients with baseline brain lesions and no previous brain radiation or surgery. Exploratory biomarker analyses using next-generation sequencing of circulating tumor DNA revealed responses in patients with and without EGFR- or MET-dependent resistance. The most frequent adverse events were rash (grouped term; 81%), infusion-related reaction (68%), and paronychia (52%). The most common grade greater than or equal to 3 treatment-related adverse events were rash (grouped term; 10%), infusion-related reaction (9%), and hypoalbuminemia (6%).
Conclusions: For patients with limited treatment options, amivantamab plus lazertinib demonstrated an antitumor activity with a safety profile characterized by EGFR- or MET-related adverse events, which were generally manageable. en-copyright= kn-copyright= en-aut-name=BesseBenjamin en-aut-sei=Besse en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotoKoichi en-aut-sei=Goto en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangYongsheng en-aut-sei=Wang en-aut-mei=Yongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeeSe-Hoon en-aut-sei=Lee en-aut-mei=Se-Hoon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MarmarelisMelina E. en-aut-sei=Marmarelis en-aut-mei=Melina E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OheYuichiro en-aut-sei=Ohe en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Bernabe CaroReyes en-aut-sei=Bernabe Caro en-aut-mei=Reyes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KimDong-Wan en-aut-sei=Kim en-aut-mei=Dong-Wan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=LeeJong-Seok en-aut-sei=Lee en-aut-mei=Jong-Seok kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=CousinSophie en-aut-sei=Cousin en-aut-mei=Sophie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=LiYongsheng en-aut-sei=Li en-aut-mei=Yongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=Paz-AresLuis en-aut-sei=Paz-Ares en-aut-mei=Luis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OnoAkira en-aut-sei=Ono en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SanbornRachel E. en-aut-sei=Sanborn en-aut-mei=Rachel E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=WatanabeNaohiro en-aut-sei=Watanabe en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=de MiguelMaria Jose en-aut-sei=de Miguel en-aut-mei=Maria Jose kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=HelisseyCarole en-aut-sei=Helissey en-aut-mei=Carole kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=ShuCatherine A. en-aut-sei=Shu en-aut-mei=Catherine A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=SpiraAlexander I. en-aut-sei=Spira en-aut-mei=Alexander I. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=TomasiniPascale en-aut-sei=Tomasini en-aut-mei=Pascale kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=YangJames Chih-Hsin en-aut-sei=Yang en-aut-mei=James Chih-Hsin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=ZhangYiping en-aut-sei=Zhang en-aut-mei=Yiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=FelipEnriqueta en-aut-sei=Felip en-aut-mei=Enriqueta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=24 ORCID= en-aut-name=GriesingerFrank en-aut-sei=Griesinger en-aut-mei=Frank kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=25 ORCID= en-aut-name=WaqarSaiama N. en-aut-sei=Waqar en-aut-mei=Saiama N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=26 ORCID= en-aut-name=CallesAntonio en-aut-sei=Calles en-aut-mei=Antonio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=27 ORCID= en-aut-name=NealJoel W. en-aut-sei=Neal en-aut-mei=Joel W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=28 ORCID= en-aut-name=BaikChristina S. en-aut-sei=Baik en-aut-mei=Christina S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=29 ORCID= en-aut-name=J?nnePasi A. en-aut-sei=J?nne en-aut-mei=Pasi A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=30 ORCID= en-aut-name=ShreeveS.

However, optimal reconstruction parameters for temporal bone imaging, especially kernel selection, remain unclear. This study aimed to identify the optimal reconstruction kernel using both objective physical image quality metrics and subjective expert assessments.
Methods: In phantom experiments, the system performance function (SPF) based on the task-based transfer function (TTF) and noise power spectrum (NPS) was calculated across 11 reconstruction kernels (Hr60?Hr98). Based on the results of the physical evaluation and clinical considerations from clinical practice, a subset of kernels was selected for visual assessment. For clinical images, two diagnostic radiologists evaluated three fine anatomical structures (i.e., stapes footplate, incudomalleolar joint, and cochlea) and overall image quality using both a ranking method and a 5-point Likert scale.
Results: TTF analysis indicated that Hr96 had the highest spatial resolution, while Hr60 showed the lowest noise in the NPS. SPF analysis identified Hr72 as providing the optimal balance between resolution and noise. Visual assessment using four reconstruction kernels (Hr60, Hr72, Hr76, and Hr84) showed that Hr76 consistently received the highest preference for overall image quality and visualization of fine structures. Statistically significant differences were observed among the kernels, with Hr60 consistently rated the lowest (p < 0.05).
Conclusion: The kernel Hr76 was found suitable for middle and inner ear diagnoses using PCD-CT, providing a good balance between spatial resolution and image noise. This finding provides a foundation for standardized reconstruction protocols in high-resolution temporal bone imaging.
Implications for practice: These findings support the use of Hr76 as a standard kernel for high-resolution temporal bone imaging and may contribute to protocol optimization in clinical PCD-CT practice. en-copyright= kn-copyright= en-aut-name=NishiiS. en-aut-sei=Nishii en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsaharaT. en-aut-sei=Asahara en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimitsuY. en-aut-sei=Morimitsu en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KajisakiS. en-aut-sei=Kajisaki en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiN. en-aut-sei=Akagi en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HondaM. en-aut-sei=Honda en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayashiH. en-aut-sei=Hayashi en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugayaA. en-aut-sei=Sugaya en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MunetomoK. en-aut-sei=Munetomo en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HigakiF. en-aut-sei=Higaki en-aut-mei=F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HirakiT. en-aut-sei=Hiraki en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IguchiT. en-aut-sei=Iguchi en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=8 en-affil=Department of Otolaryngology, Head & Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, 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=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= en-keyword=Photon-counting CT kn-keyword=Photon-counting CT en-keyword=Temporal bone imaging kn-keyword=Temporal bone imaging en-keyword=Reconstruction kernel kn-keyword=Reconstruction kernel en-keyword=Image quality kn-keyword=Image quality END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=10 article-no= start-page=908 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Comparative Study of Authoring Performances Between In-Situ Mobile and Desktop Tools for Outdoor Location-Based Augmented Reality en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, Location-Based Augmented Reality (LAR) systems have been increasingly implemented in various applications for tourism, navigation, education, and entertainment. Unfortunately, the LAR content creation using conventional desktop-based authoring tools has become a bottleneck, as it requires time-consuming and skilled work. Previously, we proposed an in-situ mobile authoring tool as an efficient solution to this problem by offering direct authoring interactions in real-world environments using a smartphone. Currently, the evaluation through the comparison between the proposal and conventional ones is not sufficient to show superiority, particularly in terms of interaction, authoring performance, and cognitive workload, where our tool uses 6DoF device movement for spatial input, while desktop ones rely on mouse-pointing. In this paper, we present a comparative study of authoring performances between the tools across three authoring phases: (1) Point of Interest (POI) location acquisition, (2) AR object creation, and (3) AR object registration. For the conventional tool, we adopt Unity and ARCore SDK. As a real-world application, we target the LAR content creation for pedestrian landmark annotation across campus environments at Okayama University, Japan, and Brawijaya University, Indonesia, and identify task-level bottlenecks in both tools. In our experiments, we asked 20 participants aged 22 to 35 with different LAR development experiences to complete equivalent authoring tasks in an outdoor campus environment, creating various LAR contents. We measured task completion time, phase-wise contribution, and cognitive workload using NASA-TLX. The results show that our tool made faster creations with 60% lower cognitive loads, where the desktop tool required higher mental efforts with manual data input and object verifications. en-copyright= kn-copyright= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Sandi KyawHtoo Htoo en-aut-sei=Sandi Kyaw en-aut-mei=Htoo Htoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RiyantokoPrismahardi Aji en-aut-sei=Riyantoko en-aut-mei=Prismahardi Aji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=location-based augmented reality (LAR) kn-keyword=location-based augmented reality (LAR) en-keyword=in-situ authoring kn-keyword=in-situ authoring en-keyword=authoring workflow kn-keyword=authoring workflow en-keyword=cognitive workload kn-keyword=cognitive workload en-keyword=NASA-TLX kn-keyword=NASA-TLX END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=2475735 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Linking structure and process in dendritic growth using persistent homology with energy analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a material analysis method that links structure and process in dendritic growth using explainable machine learning approaches. We employed persistent homology (PH) to quantitatively characterize the morphology of dendritic microstructures. By using interpretable machine learning with energy analysis, we established a robust relationship between structural features and Gibbs free energy. Through a detailed analysis of how Gibbs free energy evolves with morphological changes in dendrites, we uncovered specific conditions that influence the branching of dendritic structures. Moreover, energy gradient analysis based on morphological feature provides a deeper understanding of the branching mechanisms and offers a pathway to optimize thin-film growth processes. Integrating topology and free energy enables the optimization of a range of materials from fundamental research to practical applications. en-copyright= kn-copyright= en-aut-name=ToneMisato en-aut-sei=Tone en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoShunsuke en-aut-sei=Sato en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuniiSotaro en-aut-sei=Kunii en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraokaYasuaki en-aut-sei=Hiraoka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgawaYui en-aut-sei=Ogawa en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukidomeHirokazu en-aut-sei=Fukidome en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FoggiattoAlexandre Lira en-aut-sei=Foggiatto en-aut-mei=Alexandre Lira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsumataChiharu en-aut-sei=Mitsumata en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NagaokaRyunosuke en-aut-sei=Nagaoka en-aut-mei=Ryunosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=VaradwajArpita en-aut-sei=Varadwaj en-aut-mei=Arpita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsudaIwao en-aut-sei=Matsuda en-aut-mei=Iwao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KotsugiMasato en-aut-sei=Kotsugi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=2 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=3 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=4 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=5 en-affil=Kyoto University Institute for Advanced Study, Kyoto University kn-affil= affil-num=6 en-affil=NTT Basic Research Laboratories, NTT Corporation kn-affil= affil-num=7 en-affil=Research Institute of Electrical Communication, Tohoku University kn-affil= affil-num=8 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=9 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=10 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=11 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=12 en-affil=Institute for Solid State Physics, The University of Tokyo kn-affil= affil-num=13 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= en-keyword=Persistent homology kn-keyword=Persistent homology en-keyword=free energy analysis kn-keyword=free energy analysis en-keyword=structure-toproperty linkage kn-keyword=structure-toproperty linkage en-keyword=dendrite growth kn-keyword=dendrite growth END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=8 article-no= start-page=e0328792 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250814 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk stratification for the prediction of skeletal-related events in patients with castration-resistant prostate cancer with bone metastases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal-related events (SREs) are common in patients with bone metastases from castration-resistant prostate cancer (CRPC). Despite advances in prostate cancer treatment, clinically validated predictive models for SREs in CRPC patients with bone metastases remain elusive. This gap in prognostic tools hinders optimal patient management and treatment planning for this high-risk population. This study aimed to develop a prediction model for SRE by investigating potential risk factors and classifying them into different groups. This model can be used to identify patients at high risk of SREs who need close follow-up. Between 2004 and 2013, 68 male patients with bone metastases from CRPC who were treated at our institute were evaluated for survival without SREs and survival without SREs of the spinal cord. The study analyzed clinical data at enrollment to identify risk factors for initial and spinal SREs. Multivariate analysis revealed that a high count of metastatic vertebrae, along with visceral or lymph node metastases, were significant risk factors. Patients were categorized into four subgroups based on the number of vertebral metastases and presence of visceral or lymph node metastases: 1) extensive vertebral and both types of metastases, 2) extensive vertebral without additional metastases, 3) some vertebral with other metastases, 4) some vertebral without additional metastases. The first SRE and spinal SRE occurred significantly sooner in the first subgroup compared to others. Incidence rates at 12 months for the first SRE were 56%, 40%, 27%, and 5%, and for the first spinal SRE were 47%, 40%, 27%, and 0% respectively. Patients with extensive vertebral and additional metastases require vigilant monitoring to mitigate SREs. en-copyright= kn-copyright= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=SugiharaShinsuke en-aut-sei=Sugihara en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakihiraShota en-aut-sei=Takihira en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkezakiYoshiteru en-aut-sei=Akezaki en-aut-mei=Yoshiteru 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= 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= affil-num=7 en-affil= kn-affil= affil-num=8 en-affil= kn-affil= affil-num=9 en-affil= kn-affil= affil-num=10 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=19 article-no= start-page=9630 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Critical Requirement of Senescence-Associated CCN3 Expression in CD44-Positive Stem Cells for Osteoarthritis Progression en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage breakdown, synovial inflammation, and subchondral bone remodeling. Previous studies have shown that cellular communication network factor 3 (CCN3) expression increases with age in cartilage, and its overexpression promotes OA-like changes by inducing senescence-associated secretory phenotypes. This study aimed to investigate the effect of Ccn3 knockout (KO) on OA development using a murine OA model. Destabilization of the medial meniscus (DMM) surgery was performed in wild-type (WT) and Ccn3-KO mice. Histological scoring and staining were used to assess cartilage degeneration and proteoglycan loss. Gene and protein expressions of catabolic enzyme (Mmp9), hypertrophic chondrocyte marker (Col10a1), senescence marker, and cyclin-dependent kinase inhibitor 1A (Cdkn1a) were evaluated. Single-cell RNA sequencing (scRNA-seq) data from WT and Sox9-deficient cartilage were reanalyzed to identify Ccn3+ progenitor populations. Immunofluorescence staining assessed CD44 and Ki67 expression in articular cartilage. The effects of Ccn3 knockdown on IL-1β-induced Mmp13 and Adamts5 expression in chondrocytes were examined in vitro. Ccn3 KO mice exhibited reduced cartilage degradation and catabolic gene expression compared with WT mice post-DMM. scRNA-seq revealed enriched Ccn3-Cd44 double-positive cells in osteoblast progenitor, synovial mesenchymal stem cell, and mesenchymal stem cell clusters. Immunofluorescence showed increased CCN3+/CD44+ cells in femoral and tibial cartilage and meniscus. Ki67+ cells were significantly increased in DMM-treated Ccn3 KO cartilage, mostly CD44+. In vitro Ccn3 knockdown attenuated IL-1β-induced Mmp13 and Adamts5 expressions in chondrocytes. Ccn3 contributes to OA pathogenesis by promoting matrix degradation, inducing hypertrophic changes, and restricting progenitor cell proliferation, highlighting Ccn3 as a potential therapeutic target for OA. en-copyright= kn-copyright= en-aut-name=HabumugishaJanvier en-aut-sei=Habumugisha en-aut-mei=Janvier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiroseKazuki en-aut-sei=Hirose en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuwaharaMiho en-aut-sei=Kuwahara en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HattoriTakako en-aut-sei=Hattori en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=articular kn-keyword=articular en-keyword=cartilage kn-keyword=cartilage en-keyword=mesenchymal stem cells kn-keyword=mesenchymal stem cells en-keyword=nephroblastoma overexpressed protein kn-keyword=nephroblastoma overexpressed protein en-keyword=osteoarthritis kn-keyword=osteoarthritis END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=100718 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=Evaluation of Mycobacterium-derived plasmids for application in oral Actinomyces species en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Genetic manipulation tools are essential for elucidating the pathogenic mechanisms of microorganisms. Several species of Actinomyces, including A. israelii, are present in the oral cavity and they are the causative agents of actinomycosis. However, efficient gene-editing tools for these species have not yet been developed. In this study, the aim was to evaluate the introduction of foreign genes into Actinomyces using plasmids derived from Mycobacterium, which belong to the same class as Actinomycetes.
Methods: A truncated derivative of pYT923, pYT923S, which contains the replication origin of the M. scrofulaceum plasmid pMSC262 was constructed and introduced into A. israelii by electrotransformation.
Results: pYT923S was successfully introduced into A. israelii. The transformation efficiency of A. israelii was approximately 7?66 CFU/μg of DNA, and all transformed colonies harbored pYT923S. The plasmid recovered from A. israelii replicated in Escherichia coli.
Conclusions: pYT923S was introduced into and maintained within A. israelii. Therefore, the pYT923S vector represents a useful genetic tool for Actinomyces and it is expected to facilitate future studies on the biology and pathogenicity of Actinomyces. en-copyright= kn-copyright= en-aut-name=OharaSakiko en-aut-sei=Ohara en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShengYijuan en-aut-sei=Sheng en-aut-mei=Yijuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyaYuki en-aut-sei=Nishiya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TosaIkue en-aut-sei=Tosa en-aut-mei=Ikue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ArimuraYuki en-aut-sei=Arimura en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MeseHiroshi en-aut-sei=Mese en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OharaNaoko en-aut-sei=Ohara en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Dentistry and Oral Surgery, Fukuyama City Hospital kn-affil= affil-num=8 en-affil=Department of Operative Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Actinomyces kn-keyword=Actinomyces en-keyword=Plasmid kn-keyword=Plasmid en-keyword=Shuttle vector kn-keyword=Shuttle vector en-keyword=Transformation kn-keyword=Transformation END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=5 article-no= start-page=573 end-page=582 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diagnostic accuracy and cut-off values of serum leucine-rich alpha-2 glycoprotein for Crohn’s disease activity in the small bowel en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Small bowel (SB) lesions in Crohn’s disease (CD) are often asymptomatic despite being highly active. Fecal calprotectin (FC) is the most widely used biomarker of CD activity, but its drawbacks include a large intra-individual sample variability and the burden of collecting stool samples. Meanwhile, serum leucine-rich alpha-2 glycoprotein (LRG) has recently attracted attention as a biomarker that can address the limitations of FC. This study determined the diagnostic accuracy of LRG and its cut-off values for diagnosing CD activity in SB.
Methods This was a retrospective, multi-center study of CD patients undergoing retrograde balloon-assisted endoscopy. For ileal- and ileocolonic-type patients with a colon SES-CD score of 0, we estimated the receiver operating characteristic curve of LRG and determined the cut-off value to achieve a target sensitivity level of 80%.
Results Among 285 patients with SB lesions, LRG had an area under the curve (AUC) of 0.72 (95% CI 0.67?0.78) with a sensitivity of 80.2% and specificity of 47.2% for a cut-off value of 10.5 when diagnosing endoscopic remission (modified SES-CD???3), while it had an AUC of 0.72 (95% CI 0.65?0.78) with a sensitivity of 81.2% and specificity of 46.2% for a cut-off value of 10.1 when diagnosing complete ulcer healing (modified SES-CD???1).
Conclusion LRG was effective for diagnosing CD activity in SB, specifically with cut-off values of 10.5 and 10.1 for endoscopic remission and complete ulcer healing, respectively. A future prospective validation study will assess its clinical utility. en-copyright= kn-copyright= en-aut-name=OkitaMuneyori en-aut-sei=Okita en-aut-mei=Muneyori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenakaKento en-aut-sei=Takenaka en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraiFumihito en-aut-sei=Hirai en-aut-mei=Fumihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AshizukaShinya en-aut-sei=Ashizuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IijimaHideki en-aut-sei=Iijima en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BambaShigeki en-aut-sei=Bamba en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiToshimitsu en-aut-sei=Fujii en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeKenji en-aut-sei=Watanabe en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShimodairaYosuke en-aut-sei=Shimodaira en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShigaHisashi en-aut-sei=Shiga en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YamamuraTakeshi en-aut-sei=Yamamura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=EmotoRyo en-aut-sei=Emoto en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MatsuiShigeyuki en-aut-sei=Matsui en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Biostatistics, Nagoya University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Medicine, Fukuoka University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Medicine, Fukuoka University Faculty of Medicine kn-affil= affil-num=5 en-affil=Osaka International Medical & Science Center, Osaka Keisatsu Hospital kn-affil= affil-num=6 en-affil=Department of Fundamental Nursing, Shiga University of Medical Science kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Internal Medicine for Inflammatory Bowel Disease, Toyama University kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Neurology, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Division of Gastroenterology, Tohoku University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Nagoya University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Biostatistics, Nagoya University Graduate School of Medicine kn-affil= affil-num=15 en-affil=Department of Biostatistics, Nagoya University Graduate School of Medicine kn-affil= en-keyword=LRG kn-keyword=LRG en-keyword=Biomarker kn-keyword=Biomarker en-keyword=Crohn’s disease kn-keyword=Crohn’s disease END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=9 article-no= start-page=1662 end-page=1672 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel method for autologous peripheral blood stem cell harvest using highly concentrated sodium citrate solution replacing acid citrate dextrose solution A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: As the processed blood volume increases, a larger amount of anticoagulant (AC) is required, which leads to a serious issue of fluid dilution in large-volume leukocytapheresis (defined as ?3-fold total blood volume). We previously reported a novel method for allogeneic peripheral blood stem cell harvest (PBSCH) using highly concentrated sodium citrate (HSC; 5.32%), which shortened the procedure time and reduced the need for an AC solution without heparin. In this study, we extended this novel method to autologous PBSCH (auto-PBSCH) and compared it with patients who received auto-PBSCH using normal concentrated sodium citrate (NSC; 2.2%).
Study Design and Methods: We retrospectively analyzed consecutive auto-PBSCH data obtained using the Spectra Optia continuous mononuclear cell collection mode between May 2017 and May 2025 at our institution.
Results: Leukocytapheresis was performed using NSC in 36 patients and HSC in 22. In the HSC group, patients tended to be younger, had significantly lower body weight, and had significantly fewer hematopoietic tumors as primary diseases compared to the NSC group. After propensity score-matched cohort adjusted for patient background, the total amount of AC solution was significantly lower (694 [range, 77?1648] vs. 298?mL [range, 64?797], p?=?.02), and procedure time was significantly shorter (224 [range, 117?395] vs. 181?min [range, 103?309], p?=?.048) in the HSC group. Furthermore, the loss rates of magnesium and potassium were lower in the HSC group.
Conclusion: This novel leukocytapheresis method demonstrated the efficacy and safety in auto-PBSCH, while minimizing the patient burden. en-copyright= kn-copyright= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeMasaya en-aut-sei=Abe en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkeuchiKazuhiro en-aut-sei=Ikeuchi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimonoJoji en-aut-sei=Shimono en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=acid citrate dextrose solution A kn-keyword=acid citrate dextrose solution A en-keyword=anticoagulant kn-keyword=anticoagulant en-keyword=autologous kn-keyword=autologous en-keyword=highly concentrated sodium citrate kn-keyword=highly concentrated sodium citrate en-keyword=peripheral blood stem cell kn-keyword=peripheral blood stem cell END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=e95808 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Stratification for the Prediction of Skeletal-Related Events in Patients With Bone Metastases From Non-small Cell Lung Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal-related events (SREs) frequently occur in patients with bone metastases from non-small cell lung cancer (NSCLC). This study aimed to identify risk factors for SREs in patients with NSCLC. Based on these factors, we also aimed to stratify patients into subgroups to facilitate the assessment of SRE risk. This retrospective analysis used medical records of 139 patients with NSCLC bone metastases who received treatment at our institution between 2011 and 2014. The incidence of SREs was assessed, and SRE-free survival was analyzed using the Kaplan-Meier method. Clinical information collected at registration was assessed to identify factors associated with the onset of SREs within six months. Univariate analysis was performed using Fisher’s exact test, and multivariate analysis was performed using Cox regression. Of the 139 patients, 36 (26%) developed SREs after registration. The SRE-free survival rates were 80% and 64% at 6 and 12 months, respectively. The univariate and multivariate analyses revealed that the absence of epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangement (hazard ratio (HR): 4.51, 95% confidence interval (CI): 1.32-15.7, p = 0.017) and a lactate dehydrogenase (LDH) level ?400 U/L (HR: 8.08, 95% CI: 1.78-36.6, p = 0.0067) were risk factors for SRE presentation within six months. Patients were classified into the following three subgroups: with EGFR mutation or ALK rearrangement and LDH level <400 U/L; without EGFR mutation or ALK rearrangement and LDH level <400 U/L; with/without EGFR mutation or ALK rearrangement and LDH level ?400 U/L. The corresponding six-month SRE-free survival rates were 92%, 69%, and 34%, respectively, showing significant differences (p < 0.001). Close monitoring is recommended for patients with LDH levels ?400 U/L in daily clinical practice, particularly with the help of the proficiency of orthopedic and radiological experts, to prevent complications such as pathological fractures and paraplegia. en-copyright= kn-copyright= en-aut-name=SakamotoYoshihiro en-aut-sei=Sakamoto en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiharaShinsuke en-aut-sei=Sugihara en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=bone metastases kn-keyword=bone metastases en-keyword=epidermal growth factor receptor-tyrosine kinase kn-keyword=epidermal growth factor receptor-tyrosine kinase en-keyword=lactate dehydrogenase kn-keyword=lactate dehydrogenase en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=skeletal related events kn-keyword=skeletal related events END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=8 article-no= start-page=e90112 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250814 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Conversion to Hip Arthroplasty After Internal Fixation Failure in an Intertrochanteric Femoral Fracture: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intertrochanteric femoral fractures are mainly managed by internal fixation. However, failures such as over-telescoping, cut-out, nonunion, or implant failure can occur, especially in osteoporotic elderly patients. We report the case of a patient in whom we performed artificial hip replacement surgery after fixation failure following internal fixation of an intertrochanteric femoral fracture. We report the case of an 85-year-old woman who sustained a left intertrochanteric femoral fracture treated with a dynamic hip screw (DHS). One week postoperatively, radiographs revealed over-telescoping of the lag screw. The patient did not complain of pain, but she underwent conversion to cemented bipolar hemiarthroplasty under general anesthesia. One possible cause of over-telescoping of the lag screw after surgery was that the longitudinal fracture line in the calcar of the proximal bone fragment, as seen in the initial CT image, may have extended horizontally at the neck level. During surgery, a fracture at the same site caused the anterior medial fragment to fail, resulting in a coronal shear fracture and fixation failure. When a longitudinal fracture line is observed in the calcar of the proximal fragment, it is necessary to keep in mind that it may extend horizontally at the neck level. en-copyright= kn-copyright=

Barley Sodium Transporter HvHKT1;1 Variants and Their Functional Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Barley (Hordeum vulgare L.) employs the Na+ transporter HvHKT1;1, which is an N+-selective transporter. This study characterized the full-length HvHKT1;1 (HvHKT1;1-FL) and three mRNA variants (HvHKT1;1-V1, -V2, and -V3), which encode polypeptides of 64.7, 54.0, 40.5, and 32.9 kDa, respectively. Tissue-specific expression profiling revealed that HvHKT1;1-FL is the most abundant transcript across leaf, sheath, and root tissues under normal conditions, with the highest expression in leaves. Under 150 mM NaCl stress, HvHKT1;1-FL and its variants showed a dynamic, time-dependent expression pattern, with peak leaf expression at 2 h, sheath expression at 12 h, and root expression at 2 h, suggesting their roles in early stress response. Functional analysis using two-electrode voltage-clamp measurements demonstrated that HvHKT1;1-FL is highly selective for Na+, with minimal conductance for K+, Li+, Rb+, or Cs+. It demonstrated high Na+ transport efficiency, characterized by higher Vmax and lower Km values, while the variants showed reduced Na+ currents, lower Vmax, and higher Km values, indicating decreased Na+ transport capacity. Reversal potential analyses further confirmed Na+ selectivity, with HvHKT1;1-FL displaying the strongest preference for Na+. Notably, while all variants retained Na+ selectivity, they showed reduced efficiency, as indicated by a more negative reversal potential in low Na+ conditions. These findings highlight the functional diversity among HvHKT1;1 variants, with HvHKT1;1-FL playing a dominant role in Na+ transport. The tissue-specific regulation of these variants under salinity stress underscores their importance in barley’s adaptive responses. en-copyright= kn-copyright= en-aut-name=ImranShahin en-aut-sei=Imran en-aut-mei=Shahin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Department of Agronomy, Khulna Agricultural University kn-affil= en-keyword=Barley kn-keyword=Barley en-keyword=HvHKT1;1 kn-keyword=HvHKT1;1 en-keyword=Na+ transport kn-keyword=Na+ transport en-keyword=mRNA variants kn-keyword=mRNA variants en-keyword=TEVC kn-keyword=TEVC END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=11 article-no= start-page=e13960 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Missing the Target: A Scoping Review of the Use of Percent Weight Loss for Obesity Management en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: To co-create comprehensive targets for obesity management, we need to understand the genesis and current use of percent weight loss targets in research. The goals of our scoping review are to (1) synthesize the literature on percent weight loss targets for adults with obesity and (2) discuss the percent weight loss targets in context with their health benefits.
Methods: We searched Cochrane, MEDLINE, and EMBASE for English language, pharmaceutical, and/or behavioral intervention studies in adults with obesity where the explicit aim of the study was weight reduction defined as a percent of body weight. Reviewers screened citations and extracted data including study characteristics.
Results: From 16,164 abstracts, we included 30 citations which were mostly randomized controlled trials (RCTs) (n?=?17) or quasi-experimental studies (n?=?12) published between 1992 and 2024. Most of the studies had target weight loss goals between 3% and 10% of body weight (n?=?28), while n?=?2 had body weight loss goals of 15% or 30%. The proportion of participants who met the percent weight loss target ranged from 5.9% (nutrition only study) to 85% (pharmaceutical study). The studies reported different reasons for targeting a percentage of weight loss such as disease-specific outcomes, reduced risk of disease, or patient-reported outcomes.
Conclusion: Percent weight loss targets were based on similar research and were often not feasible nor sustainable for most participants. The design of these interventions and evaluation of obesity management would benefit from more patient-focused parameters which could help to co-design comprehensive targets for research and practice. en-copyright= kn-copyright= en-aut-name=SherifaliDiana en-aut-sei=Sherifali en-aut-mei=Diana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RaceyMegan en-aut-sei=Racey en-aut-mei=Megan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Fitzpatrick‐LewisDonna en-aut-sei=Fitzpatrick‐Lewis en-aut-mei=Donna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GreenwayMichelle en-aut-sei=Greenway en-aut-mei=Michelle kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SockalingamSanjeev en-aut-sei=Sockalingam en-aut-mei=Sanjeev kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TeohSoo?Huat en-aut-sei=Teoh en-aut-mei=Soo?Huat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=PattonIan en-aut-sei=Patton en-aut-mei=Ian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MacklinDavid en-aut-sei=Macklin en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=van RossumElizabeth?F.?C. en-aut-sei=van Rossum en-aut-mei=Elizabeth?F.?C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BusettoLuca en-aut-sei=Busetto en-aut-mei=Luca kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HornDeborah?Bade en-aut-sei=Horn en-aut-mei=Deborah?Bade kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=Patricia?NeceJ.?D. en-aut-sei=Patricia?Nece en-aut-mei=J.?D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=LeguedeMorgan?Emile?Gabriel?Salmon en-aut-sei=Leguede en-aut-mei=Morgan?Emile?Gabriel?Salmon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=PearceNicole en-aut-sei=Pearce en-aut-mei=Nicole kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Le?RouxCarel en-aut-sei=Le?Roux en-aut-mei=Carel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=ArdJamy en-aut-sei=Ard en-aut-mei=Jamy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=AlbergaAngela?S. en-aut-sei=Alberga en-aut-mei=Angela?S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=KaplanLee en-aut-sei=Kaplan en-aut-mei=Lee kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=SharmaArya?M. en-aut-sei=Sharma en-aut-mei=Arya?M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=WhartonSean en-aut-sei=Wharton en-aut-mei=Sean kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= affil-num=1 en-affil=McMaster Evidence Review and Synthesis Team;

He had been diagnosed with rheumatoid arthritis 18?years prior and had achieved remission with treatment, including methotrexate and janus kinase (JAK) inhibitor. Although routine follow-ups had not revealed any urinary abnormalities, subsequent tests detected proteinuria and hematuria in the absence of infection or other symptoms. As the urinary abnormalities persisted, with a serum albumin decrease and proteinuria measuring 5.7?g/day, indicating nephrotic syndrome, the patient was referred to our hospital for further evaluation, and a renal biopsy was performed. Light microscopy revealed mesangial cell proliferation, endocapillary proliferation and double-contoured basement membranes. Immunofluorescence microscopy showed IgA-dominant deposits in both mesangial areas and glomerular capillary walls. Transmission electron microscopy demonstrated electron-dense deposits in the mesangium and subendothelial regions, leading to the diagnosis of membranoproliferative glomerulonephritis (MPGN)-type IgA nephropathy. Immunostaining with the Gd-IgA1 (galactose-deficient IgA1)-specific antibody (KM55) was positive, consistent with the diagnosis. Following the initiation of steroid therapy, proteinuria rapidly decreased, achieving complete remission within 5?months. IgA nephropathy with MPGN-like features often presents as nephrotic syndrome, differing from the typical pathological and clinical presentation of IgA nephropathy, making differentiation from secondary MPGN and other diseases sometimes challenging. This case suggests that KM55 staining may offer additional information in differentiating atypical IgA nephropathy with non-classical pathological features. en-copyright= kn-copyright= en-aut-name=KanazawaMiyu en-aut-sei=Kanazawa en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AokiRyoya en-aut-sei=Aoki en-aut-mei=Ryoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SueMihiro en-aut-sei=Sue en-aut-mei=Mihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeHiromasa en-aut-sei=Miyake en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Okayama University Medical School kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Gd-IgA1 kn-keyword=Gd-IgA1 en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=membranoproliferative glomerulonephritis kn-keyword=membranoproliferative glomerulonephritis en-keyword=nephrotic syndrome kn-keyword=nephrotic syndrome en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=6 article-no= start-page=1100 end-page=1111 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relation between obesity and health disorders as revealed by the J-ORBIT clinical information collection system directly linked to electronic medical records (J-ORBIT 1) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction: Obesity triggers various health disorders, but information on these disorders in real-world settings remains limited. To address this knowledge gap, we developed a database directly linked to electronic medical records (EMRs). We here present the baseline data for this database, designated Japan Obesity Research Based on electronIc healTh Records (J-ORBIT).
Materials and Methods: Individuals with obesity disease diagnosed according to the criteria of the Japan Society for the Study of Obesity were registered in J-ORBIT from seven medical centers in Japan. We analyzed the relationship between body mass index (BMI), clinical characteristics, and the prevalence of obesity-related health disorders in this cohort.
Results: Data were obtained from 1,169 individuals, with a mean (±SD) age of 56.9?±?15.3?years and a BMI of 31.4?±?6.1?kg/m2. The prevalence of health disorders varied substantially across BMI categories, with a higher BMI being associated with an increased prevalence of hyperuricemia or gout, obstructive sleep apnea syndrome or obesity hypoventilation syndrome, musculoskeletal disorders, and obesity-related kidney disease, as well as with a higher frequency of both a family history of obesity and of a history of childhood obesity. Among individuals with a BMI of ?25?kg/m2, the prevalence of hypertension and dyslipidemia did not increase with BMI, whereas that of glucose intolerance decreased with increasing BMI.
Conclusions: The J-ORBIT system, which collects clinical data in real time directly from EMRs, has the potential to provide insight into obesity and its associated health conditions, thereby contributing to improved care of affected individuals. en-copyright= kn-copyright= en-aut-name=NishikageSeiji en-aut-sei=Nishikage en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

dt-pub-year=2025 dt-pub=20250807 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A pilot transcriptomic study of a novel multitargeted BRT regimen for anti?MDA5 antibody-positive dermatomyositis: improving survival over conventional therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis (MDA5-DM) is associated with severe outcomes, primarily due to rapidly progressive interstitial lung disease (RP-ILD), which is often refractory to standard therapies such as calcineurin inhibitors (e.g., tacrolimus) combined with cyclophosphamide (TC-Tx). This study evaluated the efficacy of a novel multitargeted regimen combining baricitinib, rituximab, and tacrolimus (BRT-Tx) in improving survival outcomes for MDA5-DM patients with poor prognostic factors.
Methods: Fourteen MDA5-DM patients with multiple adverse prognostic factors were studied. Seven received the BRT-Tx regimen, and the remaining seven, previously treated with TC-Tx, served as historical controls. Twelve-month survival was assessed. Transcriptome analysis was performed for six patients (BRT=3, TC=3), beginning with cluster analysis to evaluate whether changes in peripheral blood gene expression varied according to treatment or prognosis. Gene ontology analysis characterized expression profiles in survivors and distinguished treatment effects. Alterations in the type I, II, and III interferon signatures were also assessed.
Results: In the TC-Tx group, four of seven patients succumbed to RP-ILD, whereas all seven BRT-Tx patients survived the 12-month observation period. Only one BRT-Tx patient required combined rescue therapies, including plasma exchange, and one case of unexplained limbic encephalitis (LE) occurred. Cytomegalovirus reactivation was observed in both groups (BRT: 5/7; TC: 6/7). Transcriptomic analysis revealed no treatment-specific clustering of differentially expressed genes (DEGs) before and after therapy. However, survivors and nonsurvivors formed distinct clusters, with survivors showing significant posttreatment suppression of B-cell-related gene expression. Moreover, interferon signature scores were significantly lower after treatment in survivors than in nonsurvivors. BRT-Tx effectively suppressed B-cell-mediated immune responses and maintained a low interferon signature, while TC-Tx resulted in nonspecific gene suppression, and in nonsurvivors, an elevated interferon signature was observed.
Conclusion: BRT-Tx has the potential to improve survival in MDA5-DM patients by effectively targeting hyperactive immune pathways. The combination of rituximab and tacrolimus is expected to disrupt B-cell?T-cell interactions and reduce autoantibody production, whereas baricitinib may suppress both IFN and GM-CSF signaling, regulating excessive autoimmunity mediated by cells such as macrophages. Unlike TC-Tx, BRT-Tx avoids cyclophosphamide-associated risks such as infertility and secondary malignancies. Future randomized controlled trials are warranted to validate its efficacy and safety. en-copyright= kn-copyright= en-aut-name=TokunagaMoe en-aut-sei=Tokunaga en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaiYu en-aut-sei=Nakai en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoYoshiharu en-aut-sei=Sato en-aut-mei=Yoshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiratsukaMitori en-aut-sei=Hiratsuka en-aut-mei=Mitori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoYoshinori en-aut-sei=Matsumoto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakatsueTakeshi en-aut-sei=Nakatsue en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaekiTakako en-aut-sei=Saeki en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmayaharaTakatsune en-aut-sei=Umayahara en-aut-mei=Takatsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KoyamaYoshinobu en-aut-sei=Koyama en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Division of Rheumatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=DNA Chip Research Inc., Medical Laboratory kn-affil= affil-num=4 en-affil=DNA Chip Research Inc., Medical Laboratory kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Division of Rheumatology and Nephrology, Department of Internal Medicine, Nagaoka Red Cross Hospital kn-affil= affil-num=7 en-affil=Division of Rheumatology and Nephrology, Department of Internal Medicine, Nagaoka Red Cross Hospital kn-affil= affil-num=8 en-affil=Division of Dermatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Division of Rheumatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= en-keyword=anti-MDA5 antibody-positive dermatomyositis (MDA5-DM) kn-keyword=anti-MDA5 antibody-positive dermatomyositis (MDA5-DM) en-keyword=JAK inhibitor kn-keyword=JAK inhibitor en-keyword=baricitinib kn-keyword=baricitinib en-keyword=rituximab kn-keyword=rituximab en-keyword=multitargeted treatment kn-keyword=multitargeted treatment en-keyword=IFN signature kn-keyword=IFN signature en-keyword=transcriptome analysis kn-keyword=transcriptome analysis END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=17 article-no= start-page=2770 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250825 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Refining the Role of Tumor-Associated Macrophages in Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the tumor microenvironment, various immune and stromal cells, such as fibroblasts and vascular endothelial cells, contribute to tumor growth and progression by interacting with cancer cells. Tumor-associated macrophages (TAMs) have attracted attention as major players in the tumor microenvironment. The origin of TAMs is believed to be the infiltration of monocytes derived from bone marrow progenitor cells into tumor tissues and their differentiation into macrophages, whereas tissue-resident macrophages derived from yolk sacs have recently been reported. TAMs infiltrating tumor tissues act in a tumor-promoting manner through immunosuppression, angiogenesis, and the promotion of cancer cell invasion. Reflecting the nature of TAMs, increased TAM invasion and TAM-specific gene expression in tumor tissues may be the new biomarkers for cancer. Moreover, new therapeutic strategies targeting TAMs, such as transformation into immunostimulatory macrophages, suppression of TAM infiltration, and promotion of phagocytosis, are being investigated, and many clinical trials are underway. As the origin and function of TAMs are further elucidated, TAM-targeted therapy is expected to become a new option for the immunotherapy of various cancers, including oral cancers. en-copyright= kn-copyright= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TianyanPiao en-aut-sei=Tianyan en-aut-mei=Piao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArashimaTakuma en-aut-sei=Arashima en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChangAnqi en-aut-sei=Chang en-aut-mei=Anqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EainHtoo Shwe en-aut-sei=Eain en-aut-mei=Htoo Shwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SoeYamin en-aut-sei=Soe en-aut-mei=Yamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinZin Zin en-aut-sei=Min en-aut-mei=Zin Zin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiMasae en-aut-sei=Fujii en-aut-mei=Masae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=tumor-associated macrophage (TAM) kn-keyword=tumor-associated macrophage (TAM) en-keyword=oral squamous cell carcinoma (OSCC) kn-keyword=oral squamous cell carcinoma (OSCC) en-keyword=macrophage polarity kn-keyword=macrophage polarity en-keyword=invasion kn-keyword=invasion en-keyword=carcinogenesis kn-keyword=carcinogenesis END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=18 article-no= start-page=4640 end-page=4653 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Refinement of day 28 treatment response criteria for acute GVHD: a collaboration study of the JSTCT and MAGIC en-subtitle= kn-subtitle= en-abstract= kn-abstract=Overall response (OR) that combines complete (CR) and partial responses (PR) is the conventional end point for acute graft-versus-host disease (GVHD) trials. Because PR includes heterogeneous clinical presentations, reclassifying PR could produce a better end point. Patients in the primary treatment cohort from the Japanese Society for Transplantation and Cellular Therapy (JSTCT) were randomly divided into training and validation sets. In the training set, a classification and regression tree algorithm generated day 28 refined response (RR) criteria based on symptoms at treatment and day 28. We then evaluated RR for primary and second-line treatments, using the area under the receiver operating characteristic curve (AUC) and negative predictive value (NPV) for 6-month nonrelapse mortality as performance measures. RR considered patients with grade 0/1 at day 28 without additional treatment as responders. RR for primary treatment produced higher AUCs than OR with small improvement of NPVs in both validation sets: JSTCT (AUC, 0.73 vs 0.69 [P < .001]; NPV, 92.0% vs 89.6% [P < .001]) and the Mount Sinai Acute GVHD International Consortium (MAGIC; AUC, 0.71 vs 0.68 [P = .032]; NPV, 90.9% vs 89.8% [P = .009]). RR for second-line treatment produced similar AUCs but much higher NPVs than OR in both validation sets of JSTCT (AUC, 0.64 vs 0.63 [P = .775]; NPV, 74.5% vs 66.0% [P < .001]) and MAGIC (AUC, 0.67 vs 0.64 [P = .105]; NPV, 86.8% vs 76.1% [P = .004]). Classifying persistent but mild skin symptoms as responses and residual lower gastrointestinal GVHD as nonresponses were major drivers in improving the prognostic performance of RR. Our externally validated day 28 RR would serve as a better end point than conventional criteria in future first- and second-line treatment trials. en-copyright= kn-copyright= en-aut-name=AkahoshiYu en-aut-sei=Akahoshi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InamotoYoshihiro en-aut-sei=Inamoto en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SpyrouNikolaos en-aut-sei=Spyrou en-aut-mei=Nikolaos kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakasoneHideki en-aut-sei=Nakasone en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DinizMarcio A. en-aut-sei=Diniz en-aut-mei=Marcio A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AyukFrancis en-aut-sei=Ayuk en-aut-mei=Francis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChoeHannah K. en-aut-sei=Choe en-aut-mei=Hannah K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DokiNoriko en-aut-sei=Doki en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EtoTetsuya en-aut-sei=Eto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EtraAaron M. en-aut-sei=Etra en-aut-mei=Aaron M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HexnerElizabeth O. en-aut-sei=Hexner en-aut-mei=Elizabeth O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HiramotoNobuhiro en-aut-sei=Hiramoto en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HoganWilliam J. en-aut-sei=Hogan en-aut-mei=William J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HollerErnst en-aut-sei=Holler en-aut-mei=Ernst kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=KataokaKeisuke en-aut-sei=Kataoka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=KawakitaToshiro en-aut-sei=Kawakita en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=TanakaMasatsugu en-aut-sei=Tanaka en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=TanakaTakashi en-aut-sei=Tanaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=UchidaNaoyuki en-aut-sei=Uchida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=VasovaIngrid en-aut-sei=Vasova en-aut-mei=Ingrid kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=YoshiharaSatoshi en-aut-sei=Yoshihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=IshimaruFumihiko en-aut-sei=Ishimaru en-aut-mei=Fumihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=FukudaTakahiro en-aut-sei=Fukuda en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=24 ORCID= en-aut-name=ChenYi-Bin en-aut-sei=Chen en-aut-mei=Yi-Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=25 ORCID= en-aut-name=KandaJunya en-aut-sei=Kanda en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=26 ORCID= en-aut-name=NakamuraRyotaro en-aut-sei=Nakamura en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=27 ORCID= en-aut-name=AtsutaYoshiko en-aut-sei=Atsuta en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=28 ORCID= en-aut-name=FerraraJames L.

We conducted a prospective trial in patients with TI-NSAA treated with CsA monotherapy. CsA (3.5?mg/kg/day) was administered to patients with TI-NSAA aged ?16. The CsA dose was adjusted to maintain a blood CsA level of ?600?ng/mL at 2?h post-administration. Blood cell counts were assessed after 8, 16 and 52?weeks of therapy. Thirty-two evaluable patients from 21 institutions were enrolled. The median age was 63.5 (range: 16?83) years. At 8?weeks, haematological improvement, with increases in haemoglobin (Hb) ?1.5?g/dL (haematological improvement in erythrocytes [HI-E]) and platelet count ?30?×?109/L (haematological improvement in platelets [HI-P]), was observed in 0/25 (0%) and 6/32 (19%) evaluable cases respectively. HI-E and HI-P occurred in 1/25 (4%) and 10/32 (31%) patients at 16?weeks, respectively, and at 52?weeks in 5/25 (20%) and 16/32 (50%) patients respectively. Nine grade 3 adverse events (AEs) occurred in six patients, but there were no grade ?4 AEs. Ten of the 32 patients experienced grade 2 renal toxicity. Low-dose CsA is effective in TI-NSAA patients and demonstrates minimal renal toxicity. However, at least 16?weeks are necessary to adequately evaluate its efficacy. en-copyright= kn-copyright= en-aut-name=IshiyamaKen en-aut-sei=Ishiyama en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiMasahide en-aut-sei=Yamazaki en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruyamaHiroyuki en-aut-sei=Maruyama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HosonoNaoko en-aut-sei=Hosono en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiHiroki en-aut-sei=Yamaguchi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanimotoKazuki en-aut-sei=Tanimoto en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiuraHiroyuki en-aut-sei=Sugiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UsukiKensuke en-aut-sei=Usuki en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshimuraKenichi en-aut-sei=Yoshimura en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OgawaSeishi en-aut-sei=Ogawa en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KanakuraYuzuru en-aut-sei=Kanakura en-aut-mei=Yuzuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsumuraItaru en-aut-sei=Matsumura en-aut-mei=Itaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AkashiKoichi en-aut-sei=Akashi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NakaoShinji en-aut-sei=Nakao en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Hematology, Kanazawa University Hospital kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Keiju Medical Center kn-affil= affil-num=3 en-affil=Department of Hematology, Kanazawa University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, University of Fukui Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Nippon Medical School kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Japanese Red Cross Fukuoka Hospital kn-affil= affil-num=8 en-affil=Department of Hematology, Chugoku Central Hospital of Japan Mutual Aid Association of Public School Teachers kn-affil= affil-num=9 en-affil=Department of Hematology, NTT Medical Center Tokyo kn-affil= affil-num=10 en-affil=Department of Biostatistics and Health Data Science, Graduate School of Medical Science, Nagoya City University kn-affil= affil-num=11 en-affil=Department of Pathology and Tumor Biology, Institute for the Advanced Study of Human Biology (WPI-ASHBi), Kyoto University kn-affil= affil-num=12 en-affil=Sumitomo Hospital kn-affil= affil-num=13 en-affil=Department of Hematology and Rheumatology, Kindai University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Medicine and Biosystemic Science, Kyushu University Graduate School of Medical Sciences kn-affil= affil-num=15 en-affil=Department of Hematology, Kanazawa University Hospital kn-affil= en-keyword=ciclosporin kn-keyword=ciclosporin en-keyword=prospective study kn-keyword=prospective study en-keyword=renal toxicity kn-keyword=renal toxicity en-keyword=transfusion-independent non-severe aplastic anaemia kn-keyword=transfusion-independent non-severe aplastic anaemia END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=6 article-no= start-page=e098532 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Protocol for a multicentre, open-label, dose-escalation phase I/II study evaluating the tolerability, safety, efficacy and pharmacokinetics of repeated continuous intravenous PPMX-T003 in patients with aggressive natural killer cell leukaemia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Aggressive natural killer cell leukaemia (ANKL) is a rare form of NK cell lymphoma with a very low incidence and poor prognosis. While multi-agent chemotherapy including L-asparaginase has been used to treat ANKL patients, they often cannot receive adequate chemotherapy at diagnosis due to liver dysfunction. PPMX-T003, a fully human monoclonal antibody targeting the transferrin receptor 1, shows promise in treating ANKL by helping patients recover from fulminant clinical conditions, potentially enabling a transition to chemotherapy. This study aimed to evaluate the tolerability, safety, efficacy, and pharmacokinetics of repeated continuous intravenous PPMX-T003 in patients with ANKL.
Methods and analysis This multicentre, open-label, dose-escalation phase I/II study will be conducted at nine hospitals in Japan. Patients diagnosed with ANKL (whether as a primary or recurrent disease) and exhibiting abnormal liver function or hepatomegaly due to the primary disease will be included. The primary endpoint is the tolerability and safety of repeated continuous intravenous administration of PPMX-T003 in the first course, based on adverse events and dose-limiting toxicities. PPMX-T003 will be administered as a continuous intravenous infusion every 24?hours for five consecutive days, followed by a 2-day break. Pretreatment will be provided to minimise the risk of infusion-related reactions. Initial doses of PPMX-T003 will be 0.5, 1.0 or 2.0 mg/kg, with subsequent dose increases determined by the Data and Safety Monitoring Committee. The sample size is set at seven participants, with enrolment increased to up to 12 participants if dose-limiting toxicities occur, based on feasibility due to the rarity of ANKL. Descriptive statistics will summarise data according to initial dose, and pharmacokinetic analysis will be conducted based on administered dose.
Ethics and dissemination This study was approved by the institutional review boards at participating hospitals. The results will be disseminated in peer-reviewed journals.

However, the genetic basis underlying strain-level differences in virulence remains largely unresolved. To address this, we performed a comparative genomic analysis between a highly virulent strain Pta6605 and a less virulent strain Pta7375. Despite high overall genome similarity, we identified key single-nucleotide polymorphisms, including premature stop-codon mutations in seven open reading frames in Pta7375. Notably, point mutations in two regulatory genes, such as fleQ, which encodes a transcription factor essential for flagellar biogenesis and biofilm formation, and gcbB, which encodes a GGDEF domain-containing diguanylate cyclase responsible for cyclic dimeric guanosine monophosphate (c-di-GMP) synthesis, were implicated in virulence disparity. Functional analyses using deletion and locus replacement mutants in the Pta6605 background revealed that the disruption of fleQ markedly reduced motility, flagellin production, c-di-GMP accumulation, biofilm formation and virulence level mirroring the Pta7375 phenotype. The gcbB replacement mutant showed reduced disease symptom development, although c-di-GMP levels remained comparable to the Pta6605 wild type. Locus replacement between strains confirmed that a point mutation in fleQ was the primary driver of reduced motility and flagellin expression in Pta7375. These findings indicate that the reduced virulence of Pta7375 is associated with impaired regulation of flagella-related genes and disruption of the FleQ-mediated c-di-GMP signalling, underscoring the value of comparative genomics in disentangling the complex regulatory networks that govern virulence in plant pathogens. en-copyright= kn-copyright= en-aut-name=HidayatMuhammad Taufiq en-aut-sei=Hidayat en-aut-mei=Muhammad Taufiq kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaKei en-aut-sei=Yoshioka en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraTakafumi en-aut-sei=Nishimura en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsaiShuta en-aut-sei=Asai en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaSachiko en-aut-sei=Masuda en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShirasuKen en-aut-sei=Shirasu en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMikihiro en-aut-sei=Yamamoto en-aut-mei=Mikihiro 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=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Agriculture, 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=Center for Sustainable Resource Science, RIKEN-TRIP kn-affil= affil-num=6 en-affil=Center for Sustainable Resource Science, RIKEN-TRIP kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=comparative genomics kn-keyword=comparative genomics en-keyword=cyclic-di- GMP kn-keyword=cyclic-di- GMP en-keyword=fleQ kn-keyword=fleQ en-keyword=gcbB kn-keyword=gcbB en-keyword=Pseudomonas syringae kn-keyword=Pseudomonas syringae END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250807 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Performance Assessment of ChatGPT for the Board Qualification Examination of the Japanese Society for Oral and Maxillofacial Radiology en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to assess the performance and utility of ChatGPT for the board qualification examination of the Japanese Society for Oral and Maxillofacial Radiology (JSOMR). We assessed ChatGPT responses to 149 multiple-choice questions written in Japanese for the board qualification examination of the JSOMR for the 3 years from 2020 to 2022. The questions were directly entered into ChatGPT-3.5 and ChatGPT-4 models manually one by one as a prompt. The accuracy rate was calculated and classified by year, type of multiple-choice question, and level of intellectual ability, and significant differences were noted. The accuracy rate of GPT-3.5 for the 3 years was 45.0% (51.0% for 2020, 34.0% for 2021, and 50.0% for 2022), while the accuracy rate of GPT-4 was 68.5% (73.5% for 2020, 62.0% for 2021, and 70.0% for 2022) for the board qualification examination of the JSOMR. GPT-4 had a significantly higher accuracy rate than GPT-3.5 in each year. On performance classified by the type of multiple-choice questions, GPT-4 performed significantly better than GPT-3.5. However, neither model performed well with questions that required interpretation or knowledge of Japanese law. The performance of GPT-4 was significantly superior to GPT-3.5 in the board qualification examination of the JSOMR, suggesting that the use of Chat GPT, especially ChatGPT-4, would be effective as a tool for learning and preparing for the examination. en-copyright= kn-copyright= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawazuToshiyuki en-aut-sei=Kawazu en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HisatomiMiki en-aut-sei=Hisatomi en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujikuraMamiko en-aut-sei=Fujikura en-aut-mei=Mamiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NambaYuri en-aut-sei=Namba en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaSuzuka en-aut-sei=Yoshida en-aut-mei=Suzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanagiYoshinobu en-aut-sei=Yanagi en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AsaumiJunichi en-aut-sei=Asaumi en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=9 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ChatGPT kn-keyword=ChatGPT en-keyword=GPT-3.5 kn-keyword=GPT-3.5 en-keyword=GPT-4 kn-keyword=GPT-4 en-keyword=Generative AI kn-keyword=Generative AI en-keyword=Large language model kn-keyword=Large language model en-keyword=Japanese Society for Oral and Maxillofacial Radiology kn-keyword=Japanese Society for Oral and Maxillofacial Radiology END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=59 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Venous air embolism induced by burr hole drilling before dural incision in craniotomy: two case reports en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Venous air embolism (VAE) is a rare but potentially fatal complication in neurosurgery typically caused by injury to dura mater, especially venous sinuses, during craniotomy. We report two cases of VAE that occurred before dural incision.
Case presentation: Both patients underwent craniotomy under general anesthesia in a head-up position. Hemodynamic and respiratory deterioration occurred during or immediately after burr hole drilling with abnormal vital signs and transesophageal echocardiography findings, raising suspicion for VAE. Immediate management, including surgical field protection and cardiopulmonary support, stabilized the patients’ conditions. The procedure was subsequently discontinued in case 1 and modified to limited resection in case 2. Postoperative computed tomography revealed intracranial venous air within the internal jugular vein, cavernous sinus, and diploic veins.
Conclusion: These cases highlight that VAE can occur even before dural incision. Vigilant intraoperative monitoring and prompt intervention are essential for preventing potentially fatal outcomes. en-copyright= kn-copyright= en-aut-name=MotoiYohei en-aut-sei=Motoi en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaharaShuji en-aut-sei=Okahara en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniMakiko en-aut-sei=Tani en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuboiNobushige en-aut-sei=Tsuboi en-aut-mei=Nobushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Okayama Red Cross Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= en-keyword=Venous air embolism kn-keyword=Venous air embolism en-keyword=Transesophageal echocardiography kn-keyword=Transesophageal echocardiography en-keyword=Computed tomography kn-keyword=Computed tomography en-keyword=Diploic veins kn-keyword=Diploic veins en-keyword=Emissary veins kn-keyword=Emissary veins en-keyword=Burr hole drilling kn-keyword=Burr hole drilling en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=2 article-no= start-page=273 end-page=281 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=T2 high-signal-intensity zone of the spinal cord dorsal horn in patients treated with spinal cord stimulation for herpes zoster-associated pain: a retrospective case?control study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose In patients with herpes zoster-associated pain (ZAP), magnetic resonance imaging (MRI) has revealed T2 high-signal intensity zones (MRI T2 HIZ) in the dorsal horn of the spinal cord, associated with postherpetic neuralgia (PHN). We retrospectively analyzed the relationship between PHN and MRI T2 HIZ in patients with refractory ZAP in the subacute phase who underwent temporary spinal cord stimulation therapy (tSCS).
Methods This single-center, case?control study included patients who underwent tSCS for refractory ZAP between 2010 and 2018. MRIs were re-assessed for the presence of T2 HIZ in the dorsal horn of the spinal cord. Patients were divided into T2 HIZ(?+) and T2 HIZ(?) groups. Patients with a numerical rating score (NRS)???3 at the last visit were defined as PHN. The NRS values and the incidence rate of PHN were compared between the two groups.
Results Of the 67 cases extracted, 38 were included in the analysis: 22 in T2 HIZ(?+) group and 16 in T2 HIZ(?) group. No significant differences were observed in background factors between the two groups. However, the T2 HIZ(?+) group had a significantly higher NRS at the final visit (T2 HIZ(?+):3.8?±?2.1, T2 HIZ(?):1.4?±?1.5; P? Conclusion T2HIZ is detected in more than half of refractory ZAP, and pain is more likely to remain after tSCS treatment in the T2HIZ(?+) group. en-copyright= kn-copyright= en-aut-name=ArakawaKyosuke en-aut-sei=Arakawa en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaMasayuki en-aut-sei=Nakagawa en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeYoichiro en-aut-sei=Abe en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pain Management Clinic, NTT Medical Center Tokyo kn-affil= affil-num=3 en-affil=Department of Pain Management Clinic, NTT Medical Center Tokyo kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Herpes zoster kn-keyword=Herpes zoster en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Postherpetic neuralgia kn-keyword=Postherpetic neuralgia en-keyword=Refractory zoster-associated pain kn-keyword=Refractory zoster-associated pain en-keyword=Temporary spinal cord stimulation kn-keyword=Temporary spinal cord stimulation END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7 article-no= start-page=002115 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Summary of taxonomy changes ratified by the International Committee on Taxonomy of Viruses (ICTV) from the Fungal and Protist Viruses Subcommittee, 2025 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Fungal and Protist Viruses Subcommittee (SC) of the International Committee on Taxonomy of Viruses (ICTV) has received a total of eight taxonomic proposals for the 2024 annual cycle. The extent of proposed changes varied, including nomenclatural updates, creation of new taxa and reorganization of established taxa. Following the ICTV procedures, all proposals were reviewed and voted upon by the members of the Executive Committee with ratification in March 2025. As a result, a total of 52 species in the families Botourmiaviridae and Marnaviridae were renamed to comply with the mandated binomial format. A new genus has been added to the dsRNA virus family Amalgaviridae, while two new families, Splipalmiviridae (Wolframvirales) and Mycoalphaviridae (Hepelivirales), were created to classify new groups of positive-sense (+) RNA mycoviruses. The class Arfiviricetes (Cressdnaviricota) was expanded by a new order Lineavirales and a new family Oomyviridae of ssDNA viruses. Additionally, a new class Orpoviricetes was created in the kingdom Orthornavirae to classify a group of bisegmented (+)RNA viruses reported from fungi and oomycetes. Finally, the order Pimascovirales was reorganized to better depict evolutionary relationships of pithoviruses and related viruses with large dsDNA genomes. The summary of updates in the taxonomy of fungal and protist viruses presented here is limited to taxa within the remit of this Subcommittee. For information on taxonomy changes on other fungal viruses closely related to animal and/or plant viruses, please see reports from sister ICTV Subcommittees (i.e. Plant Virus SC and Animal dsRNA and ssRNA(?) Viruses SC). en-copyright= kn-copyright= en-aut-name=SabanadzovicSead en-aut-sei=Sabanadzovic en-aut-mei=Sead kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbergelChantal

Virus taxonomy is developed through a different system of annual submission of formal taxonomy proposals (TPs) that can be submitted by anyone but are typically prepared by a study group appointed by the International Committee on Taxonomy of Viruses (ICTV) and consisting of experts on a particular group of viruses. These are initially evaluated by an expert subcommittee and by the executive committee (EC) of the ICTV. EC-approved TPs are then submitted for evaluation and a ratification vote by the wider ICTV membership. Following ratification, the new taxonomy is annually updated in the Master Species List, associated databases and bioinformatic resources. The process is consistent, creates traceability in assignments and supports a fully evaluated, hierarchical classification and nomenclature of all taxonomic ranks from species to realms. The structure also facilitates large-scale and coordinated changes to virus taxonomy, such as the recent introduction of a binomial species nomenclature.
TPs are available on the ICTV website after ratification, but they are not indexed in bibliographic databases and are not easily cited. Authors of TPs do not receive citation credit for adopted proposals, and their voluntary contributions are largely invisible in the published literature. For greater visibility of TPs and their authors, the ICTV will commence the annual publication of summaries of all TPs from each ICTV subcommittee. These summaries will provide a searchable compendium of all annual taxonomy changes and additions as well as direct links to the Master Species List and other ICTV bioinformatic resources.

However, evidence regarding the efficacy of hypothermia in post-cardiac arrest syndrome (PCAS) remains unclear. Retrospective studies suggest that the clinical effectiveness of hypothermia may depend on the severity of PCAS. The R-CAST OHCA trial aims to compare the efficacy of hypothermia versus normothermia in improving 30-day neurological outcomes in patients with moderately severe PCAS following out-of-hospital cardiac arrest.
Methods and analysis The multicentre, single-blind, parallel-group, superiority, randomised controlled trial (RCT) is conducted with the participation of 35 emergency and critical care centres and/or intensive care units at academic and non-academic hospitals. The study enrols moderately severe PCAS patients, defined as those with a revised post-Cardiac Arrest Syndrome for induced Therapeutic Hypothermia score of 5.5?15.5. A target number of 380 participants will be enrolled. Participants are randomised to undergo either hypothermia or normothermia within 3?hours after return of spontaneous circulation. Patients in the hypothermia group are cooled and maintained at 34°C until 28 hours post-randomisation, followed by rewarming to 37°C at a rate of 0.25°C/hour. Patients in the normothermia group are maintained at normothermia (36.5°C?37.7°C). Total periods of intervention, including the cooling, maintenance and rewarming phases, will occur 40 hours after randomisation. Other treatments for PCAS can be determined by the treating physicians. The primary outcome is a favourable neurological outcome, defined as Cerebral Performance Category 1 or 2 at 30 days after randomisation and compared using an intention-to-treat analysis.

However, their epidemiology and optimal management remain poorly understood. The authors report a rare case of a symptomatic POAA caused by arterial dissection that was successfully treated using endovascular therapy, leading to favorable visual recovery.
OBSERVATIONS: A 77-year-old woman presented with sudden-onset visual impairment in the right eye. Ophthalmological examination revealed a defect in the right visual field. CT angiography revealed a fusiform aneurysm in the right intraorbital OphA. Digital subtraction angiography revealed a pearl and string sign, consistent with a dissecting aneurysm. A balloon test occlusion (BTO) of the OphA origin confirmed collateral circulation from the external carotid artery. Internal trapping of the OphA was performed under general anesthesia. Postoperatively, the patient’s visual function gradually improved, and complete recovery was achieved within 3 months.
LESSONS: Although POAAs are exceptionally rare, they may lead to significant visual dysfunction owing to optic nerve compression. When visual symptoms are present, prompt intervention may reverse the symptoms. Preoperative assessment of collateral circulation using BTO is essential for treatment planning. Internal trapping may be an effective strategy when sufficient collateral flow is confirmed. en-copyright= kn-copyright= en-aut-name=IzumiharaKohei en-aut-sei=Izumihara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 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=5 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=6 ORCID= en-aut-name=SotomeYuta en-aut-sei=Sotome en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawakamiMasato en-aut-sei=Kawakami en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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=11 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= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=ophthalmic artery kn-keyword=ophthalmic artery en-keyword=dissecting aneurysm kn-keyword=dissecting aneurysm en-keyword=visual impairment kn-keyword=visual impairment en-keyword=endovascular treatment kn-keyword=endovascular treatment END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=17 article-no= start-page=6122 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Potential of Kidney Exchange Programs (KEPs) in Japan for Donor-Specific Antibody-Positive Kidney Transplants: A Questionnaire Survey on KEPs and a Multi-Institutional Study Conducting Virtual Cross-Matching Simulations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To clarify the need for a kidney exchange program (KEP) in Japan by conducting a questionnaire survey on KEPs and simulated KEPs by virtual cross-matching based on past cases of transplantation avoidance. Methods: In addition to the content regarding KEPs, an electronic survey was conducted to investigate the number of cases of kidney transplant abandonment due to “immunological” reasons over the past 10 years (2012?2021). Virtual cross-matching was conducted to simulate the feasibility of avoiding immunological risks and enabling kidney transplantation in patients who were previously unable to undergo the procedure. Results: The survey received responses from 107 facilities (response rate: 81.7%). In response to the question about the necessity of a KEP in Japan, 71 facilities (66.4%) indicated that KEPs are necessary. In addition, 251 living-donor kidney transplants were abandoned for “immunological” reasons over the past decade (2012?2021). Among the 80 pairs for which detailed information was available, virtual cross-matching simulations showed that 37/80 pairs (46.3%) were donor-specific antibody (DSA)-negative for blood type-matched combinations, and 41/80 pairs (51.3%) were DSA-negative for blood type-incompatible transplants. Conclusions: The need for a KEP in Japan and its potential usefulness were demonstrated. en-copyright= kn-copyright= en-aut-name=ItoTaihei en-aut-sei=Ito en-aut-mei=Taihei kn-aut-name= kn-aut-sei=

circulating GPIHBP1 levels and neonatal outcomes in patients with gestational diabetes mellitus: a pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The prevalence of gestational diabetes mellitus (GDM) is significantly increasing. Hyperglycaemia and dyslipidaemia have been demonstrated to contribute to endothelial dysfunction linked to foetal?placental circulation. Glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) is crucial for the lipolytic processing of TG-rich lipoproteins through the anchoring of lipoprotein lipase (LPL). In this study, circulating GPIHBP1 levels during pregnancy were evaluated, and their associations with hypertriglyceridaemia and the perinatal outcomes of GDM were evaluated.
Methods: This study included 12 pregnant women with GDM and 21 pregnant women with normal glucose tolerance (NGT).
Results: No significant differences in obstetrical outcomes were detected between the two groups. In participants with NGT, circulating GPIHBP1 levels were markedly lower in the 3rd trimester than in the 2nd trimester and at delivery. In women with GDM, circulating GPIHBP1 levels were unchanged during the 3rd trimester, and circulating GPIHBP1 levels throughout the 3rd trimester were negatively correlated with neonatal birth weight percentile and umbilical venous pO2 (ρ=-0.636, p=0.026; ρ=-0.657, p=0.020).
Discussion: Our findings suggest a possible association between circulating GPIHBP1 levels and perinatal outcomes in patients with GDM. en-copyright= kn-copyright= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurookaNaoko en-aut-sei=Kurooka en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko 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= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) kn-keyword=glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) en-keyword=gestational diabetes mellitus (GDM) kn-keyword=gestational diabetes mellitus (GDM) en-keyword=perinatal outcomes kn-keyword=perinatal outcomes en-keyword=placenta kn-keyword=placenta en-keyword=triglyceride (TG) kn-keyword=triglyceride (TG) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Repeated Gravity Casting on the Microstructure and Mechanical Properties of 6061 Aluminum Alloy en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study systematically investigates the effects of repeated gravity casting on the microstructure and mechanical properties of 6061 aluminum alloy. With an increasing number of casting cycles from one to ten, grain coarsening and a decrease in dislocation density were observed, mainly due to the significant depletion of magnesium from 1.03 to 0.01% and titanium from 0.009 to 0.005%. These microstructural changes led to a decrease in solid-solution strengthening and grain-boundary strengthening, resulting in a 30% reduction in tensile strength, while ductility increased by about three times. Moreover, work hardening decreased with increasing the casting cycle, which can be attributed not only to the microstructural changes but also to the increase in stacking fault energy (SFE) associated with compositional evolution. From the transmission electron microscopy (TEM) observations, in the 1-cycle sample, Mg2Si precipitates were finely dispersed and a high amount of Mg element in the matrix, resulting in significant dislocation accumulation, whereas the 10-cycle sample exhibited weaker dislocation tangling. These microstructural evolutions provide insight into the degradation of mechanical performance in aluminum alloys subjected to multiple casting processes. en-copyright= kn-copyright= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakinoShouei en-aut-sei=Makino en-aut-mei=Shouei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagawaShota en-aut-sei=Nakagawa en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiShuhei en-aut-sei=Takeuchi en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShinzatoYoshifumi en-aut-sei=Shinzato en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MinodaTadashi en-aut-sei=Minoda en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhtsukaNaotaka en-aut-sei=Ohtsuka en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=3 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= affil-num=4 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=5 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= affil-num=6 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= affil-num=7 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= en-keyword=aluminum alloy kn-keyword=aluminum alloy en-keyword=repeated casting kn-keyword=repeated casting en-keyword=6061 kn-keyword=6061 en-keyword=microstructure kn-keyword=microstructure en-keyword=mechanical property kn-keyword=mechanical property END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251028 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced electric power generation in PZT ceramics via stress control en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to enhance the electric power generation of lead zirconate titanate piezoelectric (PZT) ceramics by optimizing stress distribution. Specifically, it focused on applying high stress over a broad area of the PZT ceramic to induce shape deformation in the PZT plate. Pre-straining the PZT plate into an arch shape improved voltage generation, reaching its peak at a maximum deflection of 0.04?mm due to the expanded and intensified stress distribution. However, exceeding this deflection threshold led to a decline in voltage output due to material degradation, including crack formation and 90° domain switching. Finite element analysis confirmed that the increased stress distribution in the pre-strained PZT plate contributed to higher voltage output. Additionally, electron backscatter diffraction analysis revealed that at higher pre-strains (deflection of 0.08?mm), 90°domain switching occurred, resulting in increased internal strain and potential crack formation. Experimental investigations using bulk PZT rods further demonstrated that moderate pre-straining effectively enhanced voltage output. en-copyright= kn-copyright= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimazuItsuki en-aut-sei=Shimazu en-aut-mei=Itsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= en-keyword=PZT ceramic kn-keyword=PZT ceramic en-keyword=Electric voltage kn-keyword=Electric voltage en-keyword=Piezoelectric effect kn-keyword=Piezoelectric effect en-keyword=Stress distribution kn-keyword=Stress distribution END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Upgrading Recycle Technology for Iron Removal in ADC12 Alloy Using Gravity and Magnetic Force en-subtitle= kn-subtitle= en-abstract= kn-abstract=As there is a technical issue to remove iron elements during aluminum recycling process, an attempt was made to evaluate the effectiveness of magnetic and gravitational separation methods for removing iron from Al-Si-Cu alloy (ADC12). A rare-earth samarium?cobalt (SmCo) magnet was employed during the solidification process to attract Fe-rich eutectic structures. The microstructural analysis revealed that block-like Fe-Cr-Si-based phases formed preferentially near the magnet and at the bottom of the crucible, suggesting that magnetic and gravity attraction contributed to the localized segregation of these phases. However, other Fe-based phases, including Fe-Si-based ones, are not strongly affected by magnet. Additionally, prolonged heating in the solid?liquid coexistence (SLC) region at 577 °C for 10 h led to the settling of a largely grown Fe-Cr-Si-rich crystal at the bottom of the crucible due to gravity. Other structures, such as Si-rich eutectic phases, were not influenced by gravity, which may be caused by the low density of Si compared to Fe one. From this approach, combining magnetic attraction and gravitational settling is a promising method to promote the removal of iron impurities from aluminum alloys. en-copyright= kn-copyright= en-aut-name=OkayasuM. en-aut-sei=Okayasu en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiS. en-aut-sei=Takeuchi en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SyahidM. en-aut-sei=Syahid en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkedaT. en-aut-sei=Ikeda en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Mechanical Engineering, Hasanuddin University kn-affil= affil-num=4 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= en-keyword=aluminum alloy kn-keyword=aluminum alloy en-keyword=upgrade recycle kn-keyword=upgrade recycle en-keyword=iron kn-keyword=iron en-keyword=microstructure kn-keyword=microstructure en-keyword=mechanical property kn-keyword=mechanical property END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=7 article-no= start-page=5143 end-page=5150 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250429 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electric Power Generation of PZT Piezoelectric Ceramics Using Both Direct and Inverse Piezoelectric Effects en-subtitle= kn-subtitle= en-abstract= kn-abstract=The power generation characteristics of lead zirconate titanate (PZT) piezoelectric ceramics (E-PZT) were experimentally investigated using a specialized PZT system which utilizes both the direct and inverse piezoelectric effects inherent to PZT materials. Specifically, electric voltage was generated from the vibration of E-PZT through the inverse piezoelectric effect, induced by mechanical energy transferred from the vibration of a PZT piezoelectric ceramic plate, such as a buzzer (B-PZT). In this system, an insulating material was placed between the B-PZT and E-PZT plates to address the electrical conductivity of the PZT ceramic. Various insulating materials with different thicknesses and different hardness were prepared. Additionally, the PZT systems were mounted in several distinct configurations to evaluate their power generation performance: a fully fixed around the PZT plate and a free-hanging setup. The influence of insulation materials and mounting conditions on electrical output was analyzed at various loading conditions, e.g., loading value and frequency. The results demonstrated that the generated electric voltage decreased with increasing insulation thickness and hardness, suggesting that thinner and softer insulating materials enhance output voltage. Conversely, when the PZT system was securely fixed around the PZT plate with an appropriate fixture, a higher and more stable electric voltage was generated. The voltage generated also varied by the loading condition, which is related to the strain value of the E-PZT plate, demonstrating a linear relationship between the strain and the output voltage. Notably, the strain was significantly influenced by resonant frequencies, which played a crucial role in achieving higher voltage outputs. Based on these experimental results, two power generation systems have been proposed. en-copyright= kn-copyright= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimazuItsuki en-aut-sei=Shimazu en-aut-mei=Itsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= en-keyword=PZT ceramic kn-keyword=PZT ceramic en-keyword=electric voltage kn-keyword=electric voltage en-keyword=inverse piezoelectric effect kn-keyword=inverse piezoelectric effect en-keyword=resonant frequency kn-keyword=resonant frequency END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=27-28 article-no= start-page=e70357 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Algebraic Connectivity Maximizing Regular Graphs: Special Case Analysis and Depth‐First Search en-subtitle= kn-subtitle= en-abstract= kn-abstract=The algebraic connectivity is an indicator of how well connected a graph is.

In this paper, taking into account that homogeneous networks are modeled as regular graphs, we tackle the following problem: given a pair (?, ?) of positive integers such that ? is less than ? and kn is an even number, find a ?-regular graph with ? vertices that have the maximum algebraic connectivity. We first consider some special cases and derive solutions through theoretical analysis. We next present depth-first search algorithms for solving the problem, which reduce the search space by making use of some known properties of the regular graph and the algebraic connectivity.We also show the results of execution of the proposed algorithms for the values of ? up to 12. en-copyright= kn-copyright= en-aut-name=KurahashiMasashi en-aut-sei=Kurahashi en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SalaaniNajd en-aut-sei=Salaani en-aut-mei=Najd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MigitaTsuyoshi en-aut-sei=Migita en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiNorikazu en-aut-sei=Takahashi en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Polytech Sorbonne, Sorbonne 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= en-keyword=algebraic connectivity kn-keyword=algebraic connectivity en-keyword=depth-first search kn-keyword=depth-first search en-keyword=optimization kn-keyword=optimization en-keyword=pruning kn-keyword=pruning en-keyword=regular graph kn-keyword=regular graph END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=9 article-no= start-page=e92587 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=The Intranasal Administration of Semaphorin 3A Inhibitor in a Mouse Model of Olfactory Disorder en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the effects of intranasal administration of a semaphorin 3A inhibitor (Sema3A-I) in a mouse model of olfactory disorder, where olfactory sensory neuron (OSN) axons had been severely damaged. We performed axotomy (transection of OSN axons) of the OSNs in mice and administered Sema3A?I intranasally to seven mice and saline to another seven mice. Following treatment, we assessed the thickness of the olfactory epithelium and the regeneration ratio of OSN axons. Intranasal administration of Sema3A-I did not significantly promote OSN regeneration, axonal outgrowth, or improve axonal projection compared to saline administration. Although Sema3A-I administration showed some promotion of axonal outgrowth, the difference was not statistically significant. Continuous subcutaneous administration of Sema3A-I in rats after axotomy promotes OSN regeneration and axonal outgrowth. Given that intranasal administration is minimally invasive, we believe that it may still be a feasible route when combined with additional treatment strategies. Further investigation into administration methods and therapeutic combinations is warranted. en-copyright= kn-copyright= en-aut-name=MuraiAya en-aut-sei=Murai en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NodaMinori en-aut-sei=Noda en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuAiko en-aut-sei=Shimizu en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaharaJunko en-aut-sei=Takahara en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Technical Support for Medical Science, Department of Comprehensive Technical Solutions, Okayama University kn-affil= affil-num=5 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University kn-affil= en-keyword=axon growth kn-keyword=axon growth en-keyword=intranasal administration kn-keyword=intranasal administration en-keyword=olfactory disorder kn-keyword=olfactory disorder en-keyword=olfactory sensory neurons kn-keyword=olfactory sensory neurons en-keyword=semaphorin3a kn-keyword=semaphorin3a END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=10 article-no= start-page=1483 end-page=1493 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Biologics and Small‐Molecule Therapies in Netherton Syndrome: A Comprehensive Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Netherton syndrome (NS) is a rare congenital ichthyosis caused by loss-of-function mutations in the SPINK5 gene, leading to defective expression of the serine protease inhibitor LEKTI. Dysregulated epidermal protease activity results in impaired skin barrier function and chronic inflammation, accompanied by complex immune profiles. NS patients commonly show activation of the inflammatory axis, centered on IL-17 and IL-36, in the skin and blood, and show a psoriasis-like shift to Th17. Conversely, the immune profile differs depending on the clinical type, with ichthyosis linearis circumflexa type characterized by complement activation and Th2-type allergic responses, and scaly erythroderma type characterized by a type I IFN signature and Th9-type allergic responses. While symptomatic treatments such as emollients and topical corticosteroids have been the mainstay of care, recent advances have opened new therapeutic avenues involving biologic agents and oral small-molecule immunomodulators. This review provides a comprehensive overview of the current clinical landscape and future directions of biologics (e.g., dupilumab, secukinumab, ustekinumab) and small-molecule therapies (e.g., JAK inhibitors such as tofacitinib, baricitinib, and upadacitinib) in the treatment of NS. Though evidence remains limited to case reports and small series, preliminary data suggest that cytokine-targeted interventions?particularly those inhibiting IL-4, IL-13, IL-17, IL-36, and JAK pathways?may offer tangible clinical benefits. Well-designed clinical trials and mechanistic investigations are crucial to establishing their place in NS management. en-copyright= kn-copyright= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MukaiTomoyuki en-aut-sei=Mukai en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SunagawaKo en-aut-sei=Sunagawa en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HasuiKen‐ichi en-aut-sei=Hasui en-aut-mei=Ken‐ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritaAnri en-aut-sei=Morita en-aut-mei=Anri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomuraHayato en-aut-sei=Nomura en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OuchidaMamoru en-aut-sei=Ouchida en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Molecular Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=9 article-no= start-page=e91856 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Incidence and Factors Influencing Locomotive Syndrome in Cancer Patients Living in the Community en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Investigating locomotive syndrome (LS) of cancer survivors in the community will help clarify the importance of rehabilitation for cancer survivors in the community and provide a basis for exploring effective interventions. The primary purpose of this study was to conduct a comparison of LS, fatigue, psychological problems, and physical activity in cancer survivors and those without cancer in the community. The secondary purpose was to analyze factors influencing LS in cancer patients.
Methods The study involved 59 cancer patients undergoing chemotherapy at home and 59 people without cancer. The cancer patients were those undergoing chemotherapy as outpatients and constituted the cancer group. The non-cancer people were living in the community and constituted the non-cancer group.
Cancer and non-cancer groups were surveyed and measured for LS, fatigue, psychological problems, and physical activity. The cancer group was also surveyed for the duration of chemotherapy treatment and the presence or absence of bone metastases.
Results The cancer group was significantly more likely than the non-cancer group to have LS stage 2, to have fatigue, and to have psychological problems. Fatigue and psychological problems were significantly associated with LS stage 2.
Conclusions Cancer patients in the community need to be assessed regularly by healthcare providers and interventions should be made according to their condition. en-copyright= kn-copyright= en-aut-name=AkezakiYoshiteru en-aut-sei=Akezaki en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KikuuchiMasato en-aut-sei=Kikuuchi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiharaShinsuke en-aut-sei=Sugihara en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Physical Therapy, Kochi Professional University of Rehabilitation kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, National Hospital Organization Shikoku Cancer Center 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, National Hospital Organization Shikoku Cancer Center kn-affil= en-keyword=cancer kn-keyword=cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=factor kn-keyword=factor en-keyword=locomotive syndrome kn-keyword=locomotive syndrome en-keyword=rehabilitation kn-keyword=rehabilitation END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=20 article-no= start-page=3351 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251017 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tertiary Lymphoid Structures Are Associated with Favorable Clinical Outcomes and Negatively Correlated with Cancer-Associated Fibroblasts in Esophageal Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Esophageal cancer remains a highly aggressive malignant tumor with poor prognosis, despite advances in combination therapies and novel immunotherapies. Tertiary lymphoid structures (TLSs), characterized by densely packed CD20+ B cells in a germinal-center-like structure, have recently been recognized as immune-stimulating components within the tumor microenvironment. In contrast, cancer-associated fibroblasts (CAFs) are stromal cells expressing fibroblast-activating protein (FAP) involved in immunosuppression. Methods: In this retrospective study, 124 clinical samples from patients who underwent radical surgery for esophageal cancer at our institute were analyzed. We investigated whether TLSs could serve as a prognostic factor and examined their association with tumor microenvironment factors. Results: The presence of TLSs was an independent prognostic factor for overall and progression-free survival in multivariate analyses. A high level of TLS formation correlated with better nutritional status, fewer M2 macrophages, and greater plasma cell infiltration. Additionally, little TLS formation was observed in areas with abundant CAFs, and quantitative analyses revealed a significant negative correlation between TLSs and CAFs. Conclusions: TLSs enhance antitumor immunity via macrophages and plasma cells and can be a valuable prognostic indicator in patients undergoing surgery for esophageal cancer. Targeting CAFs may prove to be a promising therapeutic strategy to enhance tumor-immunity-related TLSs. en-copyright= kn-copyright= en-aut-name=KunitomoTomoyoshi en-aut-sei=Kunitomo

emissions from straw-amended paddy soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The independent incorporation of biochar and sediment microbial fuel cells (SMFCs) into paddy soil has been shown to reduce methane (CH4) emissions. However, the application of rice straw into paddy soil enhances the availability of labile carbon that stimulates methanogen growth, counteracting the mitigation effects of both methods. This study, therefore, aimed to investigate the effect of coupling biochar and SMFC on CH4 and CO2 emissions from straw-amended paddy soil.
Materials and methods Single chamber SMFC setups constructed using acrylic columns (height, 25 cm; inner diameter, 9 cm) with six treatments were established using soil amended with 0% (0BC), 1% (1BC), and 2% (2BC) biochar: with and without SMFC conditions. Stainless steel mesh (15?×?3 cm) and graphite felt (6?×?5 cm) were used as anode and cathode materials, respectively.
Results Cumulative emission of CH4 in the 0BC treatment with SMFC was 39% less than in that without SMFC. Biochar addition and SMFC operation together further reduced CH4 emission by 57% and 60% in 1BC and 2BC treatments, respectively, compared to that in the 0BC treatment without SMFC operation. The relative abundance of microbial communities indicated methane-oxidizing bacteria were enriched in the presence of biochar and hydrogenotrophic Methanoregula were suppressed by SMFC operation. This suggested that SMFC mainly inhibited CH4 production by outcompeting hydrogenotrophic archaea.
Conclusion The use of biochar made from leftover rice straw has an interactive effect on SMFC operation and both methods can be used to reduce CH4 emission from straw-amended paddy soil. en-copyright= kn-copyright= en-aut-name=BekeleAdhena Tesfau en-aut-sei=Bekele en-aut-mei=Adhena Tesfau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro 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= en-aut-name=HashiguchiAyumi en-aut-sei=Hashiguchi en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkaoSatoshi en-aut-sei=Akao en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=7 en-affil=Department of Comprehensive Technical Solutions, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Electrogenesis kn-keyword=Electrogenesis en-keyword=Methane oxidation kn-keyword=Methane oxidation en-keyword=Pyrolysis kn-keyword=Pyrolysis en-keyword=Paddy field kn-keyword=Paddy field en-keyword=Methanogens kn-keyword=Methanogens END start-ver=1.4 cd-journal=joma no-vol=130 cd-vols= no-issue=10 article-no= start-page=e2025JB032215 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical Conductivity of Carbonated Hydrous Basaltic Melt: Implications for the Conductivity Anomaly Beneath the Ocean Floors en-subtitle= kn-subtitle= en-abstract= kn-abstract=We measured the electrical conductivity of CO2 and H2O-bearing basaltic melts up to 1750 K at 2 GPa, corresponding to pressure around the lithosphere-asthenosphere boundary. The electrical conductivity of the dry and hydrous samples is comparable to those reported by previous studies on the Fe-free basaltic melt. The substantial CO2 can limit the water solubility in basaltic melt at 2 GPa. Both CO2 and H2O, which cannot completely dissolve in the melt, coexist as fluid phases, resulting in reduced electrical conductivity of the basaltic melt, which has a lower water content relative to the amount of volatile components in the bulk starting system. The activation enthalpy of basaltic melt is markedly higher than those of more evolved silicate melts, especially on the H2O-poor condition, due to the more enriched alkaline earth elements. The present results suggest that an overall melt fraction of 0.1?5.3 vol% is needed to account for the high electrical conductivity anomalies (10?1.3 to 10?0.3 S/m) beneath the oceanic plate near the East Pacific Rise and Cocos plate. However, for those regions where the electrical conductivity is extremely high (?10?0.3 S/m), more than 6 wt% H2O is expected to incorporate to maintain a melt fraction that will not trigger mechanical instability. In turn, it requires a low CO2 budget or degree of carbonation within these regions. en-copyright= kn-copyright= en-aut-name=ZhaoBin en-aut-sei=Zhao en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuJintao en-aut-sei=Zhu en-aut-mei=Jintao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HeJinze en-aut-sei=He en-aut-mei=Jinze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=electrical conductivity kn-keyword=electrical conductivity en-keyword=basaltic melts kn-keyword=basaltic melts en-keyword=oceanic floors kn-keyword=oceanic floors en-keyword=high pressure kn-keyword=high pressure END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250923 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=INF2-Related Charcot?Marie?Tooth Disease in a Japanese Cohort: Genetic and Clinical Insights en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: INF2 mutations cause focal segmental glomerulosclerosis (FSGS) and Charcot?Marie?Tooth disease (CMT). Accurate genetic diagnosis is critical, as INF2-related FSGS is typically resistant to immunotherapy yet rarely recurs after transplantation, and its associated neuropathy can mimic treatable immune-mediated disorders such as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP).
Methods: We performed a multicenter study investigating 3329 Japanese patients with inherited peripheral neuropathies/CMT who underwent gene panel sequencing or whole-exome analysis between 2007 and 2024. Clinical data, including electrophysiological assessments, were obtained from the patients' medical records.
Results: We identified six pathogenic INF2 variants in eight patients, all of which were located within the diaphanous inhibitory domain. Structural modeling revealed clustering of variants near the diaphanous autoregulatory domain-binding pocket, which is critical for INF2 autoinhibition. Clinically, all cases were sporadic, with a median age at neurological onset of 9?years. All patients exhibited lower limb weakness, and 6/8 (75%) had sensory disturbances. All patients also developed kidney dysfunction, with 7/8 (88%) progressing to end-stage renal disease at a median age of 15?years. Furthermore, all patients showed demyelinating neuropathy, and 2/8 (25%) received immunotherapy due to suspected immune-mediated neuropathy.
Conclusion: Although INF2 variants are a rare cause of CMT in Japan, they should be considered in pediatric patients with demyelinating neuropathy and early-onset proteinuria, even in the absence of a family history. Blood and urine tests assessing renal dysfunction can provide guidance for appropriate genetic testing. en-copyright= kn-copyright= en-aut-name=YanoChikashi en-aut-sei=Yano en-aut-mei=Chikashi

kn-abstract=Patients with vestibular schwannomas (VSs) present with vestibulocochlear nerve dysfunction such as vertigo and tinnitus. VSs occasionally develop communicating hydrocephalus as a complication, which is typically characterized by an insidious progression of symptoms. We report a case of an 84-year-old female patient with a VS who developed gait disturbance and consciousness impairment over a three-week period, ultimately resulting in an inability to walk and communicate. A thorough evaluation ruled out encephalitis and other differential diagnoses. Imaging studies demonstrated findings consistent with communicating hydrocephalus, and a tap test temporarily improved her consciousness disturbances. The patient underwent ventriculoperitoneal shunting and stereotactic radiosurgery (SRS), after which both consciousness and gait disturbances dramatically improved 10 days postoperatively. The subacute development of symptoms due to normal pressure hydrocephalus associated with VSs is rare. Furthermore, to the best of our knowledge, this is the first reported case of severe gait impairment and disturbance of consciousness progressing within a short period. This case highlights the importance of considering communicating hydrocephalus associated with VSs as a differential diagnosis, even in cases of subacute consciousness disturbance. We also discuss the pathophysiology of hydrocephalus in relation to cerebrospinal fluid (CSF) clearance into the extracranial space. en-copyright= kn-copyright= en-aut-name=YanoSatoka en-aut-sei=Yano en-aut-mei=Satoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaAkatsuki en-aut-sei=Kubota en-aut-mei=Akatsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaiMizuho en-aut-sei=Kawai en-aut-mei=Mizuho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YashitaDaiki en-aut-sei=Yashita en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SatakeWataru en-aut-sei=Satake en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaKaoru en-aut-sei=Yamada en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinyaYuki en-aut-sei=Shinya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyawakiSatoru en-aut-sei=Miyawaki en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IwatsuboTakeshi en-aut-sei=Iwatsubo en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TodaTatsushi en-aut-sei=Toda en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Neurology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=2 en-affil=Department of Neurology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Neurology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Neurology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=7 en-affil=Department of Neuropathology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=8 en-affil=Department of Neurosurgery, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=9 en-affil=Department of Neurosurgery, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Neuropathology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= affil-num=11 en-affil=Department of Neurology, The University of Tokyo Graduate School of Medicine and Faculty of Medicine kn-affil= en-keyword=communicating hydrocephalus kn-keyword=communicating hydrocephalus en-keyword=csf dynamics kn-keyword=csf dynamics en-keyword=disorder of consciousness kn-keyword=disorder of consciousness en-keyword=ventriculoperitoneal shunting kn-keyword=ventriculoperitoneal shunting en-keyword=vestibular schwannoma kn-keyword=vestibular schwannoma END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=417 end-page=431 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of?a?Startup Program Identification for?Efficient and?Accurate IoT Security Investigations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Not all file in firmware are executed while using Internet of Things (IoT) devices and hundreds to approximately a thousand executable and linkable format files exist in one firmware. Therefore, security investigations without prioritization may lead to investigate programs that are not executed while using IoT devices first. This has resulted in inefficient security investigations. To perform efficient security investigations, we proposed a method that can identify programs executed during the startup process. However, only two firmware were used for the evaluation which can only evaluate one of the two startup sequences in the OpenWrt-based firmware. In addition, security investigations to validate whether the proposed method addresses the problem of inefficient security investigations were limited to OpenWrt-based firmware. In this study, we use more firmware data for evaluation and validation. We use nine firmware not used in previous studies including startup methods that have not previously been used for evaluation. In addition, we increase the number of firmware used for validation to 225. The evaluation results demonstrate that the proposed method can identify with only few false positives. The validation demonstrates that efficiency can be improved and prioritizing investigations by considering the proposed method result is worthwhile. en-copyright= kn-copyright= en-aut-name=ShimamotoYuta en-aut-sei=Shimamoto en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PhinyodomJiratchaya en-aut-sei=Phinyodom en-aut-mei=Jiratchaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshimotoRyota en-aut-sei=Yoshimoto en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UekawaHiroyuki en-aut-sei=Uekawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkiyamaMitsuaki en-aut-sei=Akiyama en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=School of Engineering, 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=NTT Social Informatics Laboratories kn-affil= affil-num=5 en-affil=NTT Social Informatics Laboratories kn-affil= affil-num=6 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Internet of Things kn-keyword=Internet of Things en-keyword=Firmware kn-keyword=Firmware en-keyword=Startup script kn-keyword=Startup script en-keyword=SysVinit kn-keyword=SysVinit END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=e95411 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Primary Lacrimal Sac Diffuse Large B-cell Lymphoma Treated With Local Radiotherapy Alone: A Case With No Relapse After 21 Years of Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary lacrimal sac lymphoma is rare and diagnosed as diffuse large B-cell lymphoma in a predominant histopathological type. Systemic chemotherapy would be the standard of care, but local radiotherapy may be a treatment option toward a localized lesion. The present patient is a 54-year-old otherwise healthy woman with a right lacrimal sac mass, which was proven by excisional biopsy to be diffuse large B-cell lymphoma. Since she did not have any other systemic lesions on gallium scintigraphy and neck-to-abdominal computed tomography scans, which were the standard procedure at that time, she underwent local radiotherapy at 40 Gy. Two years later, at the age of 56 years, she developed radiation retinopathy with macular edema in the right eye and had spotty laser photocoagulation in the nasal half of the fundus. At the age of 57 years, she developed radiation cataract and underwent cataract surgery with intraocular lens implantation in the right eye. At the age of 58 years, the macular edema in the right eye became worse and remained active, resulting in poor visual acuity of 0.1. She thus underwent 25-gauge vitrectomy in the right eye to peel off the adhering posterior vitreous surface, together with the internal limiting membrane, as the standard procedure at that time. The visual acuity in the right eye was elevated to 0.6. She maintained the visual acuity afterward and had no relapse of lymphoma in 21 years from the diagnosis of primary right lacrimal sac diffuse large B-cell lymphoma. Local radiotherapy would still be a treatment option for localized lymphoma lesions such as primary lacrimal sac lymphoma. 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=TakemotoMitsuhiro en-aut-sei=Takemoto en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Healthcare Science, 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=Radiotherapy, Himeji Red Cross Hospital kn-affil= en-keyword=diffuse large b-cell lymphoma kn-keyword=diffuse large b-cell lymphoma en-keyword=excisional biopsy kn-keyword=excisional biopsy en-keyword=lacrimal sac kn-keyword=lacrimal sac en-keyword=laser photocoagulation kn-keyword=laser photocoagulation en-keyword=macular edema kn-keyword=macular edema en-keyword=pathology kn-keyword=pathology en-keyword=radiation cataract kn-keyword=radiation cataract en-keyword=radiation retinopathy kn-keyword=radiation retinopathy en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=vitrectomy kn-keyword=vitrectomy END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=20 article-no= start-page=10072 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurofibromin Encoded by the Neurofibromatosis Type 1 (NF1) Gene Promotes the Membrane Translocation of SPRED2, Thereby Inhibiting the ERK Pathway in Breast Cancer Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neurofibromin (NF) inhibits the RAS/RAF/ERK pathway through its interaction with SPRED1 (Sprouty-related EVH1 domain-containing protein 1). Here, we investigated the functional relationship between NF and SPRED2 in breast cancer (BC). Human BC cell lines were transfected to downregulate or overexpress NF and SPRED2 and subsequently subjected to functional assays. Protein and mRNA levels were analyzed by Western blotting and RT-qPCR, respectively. Protein?protein interactions were examined by immunoprecipitation. Database analyses and immunohistochemistry (IHC) of BC tissues were performed to validate the in vitro findings. Downregulating NF or SPRED2 expression in BC cells enhanced cell proliferation, migration and invasion accompanied by RAF/ERK activation, whereas overexpression produced opposite effects. NF formed a protein complex with SPRED2 and facilitated its translocation to the plasma membrane. By IHC, SPRED2 membrane localization was absent in NF-negative luminal A and triple-negative BC (TNBC) but present in a subset of luminal A BC. By database analyses, both NF1 and SPRED2 mRNA levels were reduced in BC tissues, and luminal A BC patients with high expression of both NF1 and SPRED2 mRNA exhibited improved relapse-free survival. These results suggest a critical role for the NF?SPRED2 axis in BC progression and highlight it as a potential therapeutic target. en-copyright= kn-copyright= en-aut-name=Su PwintNang Thee en-aut-sei=Su Pwint en-aut-mei=Nang Thee kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYuze en-aut-sei=Wang en-aut-mei=Yuze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cell Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=neurofibromatosis type 1 kn-keyword=neurofibromatosis type 1 en-keyword=neurofibromin kn-keyword=neurofibromin en-keyword=RAS/RAF/ERK kn-keyword=RAS/RAF/ERK END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=20 article-no= start-page=3287 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Neoadjuvant Chemotherapy with Gemcitabine Plus S-1 in Patients with Resectable Pancreatic Ductal Adenocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Although neoadjuvant chemotherapy (NAC) is not universally recommended for resectable pancreatic ductal adenocarcinoma (PDAC), NAC with gemcitabine plus S-1 (NAC-GS) has become a commonly used regimen for resectable PDAC in Japan. Furthermore, the impact of achieving textbook outcomes (TO) in patients receiving NAC-GS remains unclear. Methods: This retrospective study included 265 patients who were diagnosed with resectable PDAC at our institution between January 2009 and December 2023. Patients were categorized into two groups: the NAC-GS group (n = 81; 2019?2023) and the upfront surgery (UFS) group (n = 164; 2009?2018). After comparing the clinical outcomes between groups, multivariate analyses for survival were performed. Additionally, outcomes stratified by the achievement of the modified TO were analyzed in the NAC-GS group. Results: The completion rate of NAC-GS was 90.1%. Patients in the NAC-GS group exhibited significantly longer survival than those in the UFS group (2-year recurrence-free survival: 61.4% vs. 37.9%, p < 0.01; 2-year overall survival: 83.2% vs. 61.2%, p < 0.01). Multivariate analyses identified lymph node metastasis, NAC-GS induction, and completion of adjuvant chemotherapy as factors significantly associated with improved survival. Moreover, among patients who received NAC-GS, those who achieved modified TO demonstrated significantly longer survival than those who did not. Conclusions: This study demonstrated the clinical efficacy of NAC-GS in patients with resectable PDAC. Induction of NAC-GS was significantly associated with improved long-term outcomes. In multidisciplinary treatment strategies for PDAC, achieving a modified TO may lead to improved survival of patients undergoing NAC-GS. en-copyright= kn-copyright= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya 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=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=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, 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 Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=neoadjuvant chemotherapy kn-keyword=neoadjuvant chemotherapy en-keyword=pancreatic cancer kn-keyword=pancreatic cancer en-keyword=resectable kn-keyword=resectable en-keyword=textbook outcome kn-keyword=textbook outcome END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=10 article-no= start-page=105028 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluating the effects of electrolytes on the interaction forces between alumina surfaces in polyacrylic acid solutions using atomic force microscopy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Evaluation and control of ceramic slurry at the microscopic level are critical to ensure consistent quality in manufactured ceramics. Notably, metal ions such as Mg2+ and Al3+ are common in ceramic slurries and significantly influence the stability of particle. This study applied atomic force microscopy to investigate the interaction forces between alumina particle surfaces in the presence of different concentrations of three metal ions and polyacrylic acid (PAA), a widely used dispersant.
The attractive forces observed at low PAA concentrations were attributed to polymer bridging between alumina surfaces, whereas the repulsive forces observed at high PAA concentrations were attributed to the domination of steric repulsion between adsorbed PAA molecules. The presence of multivalent metal ions, such as Mg2+ and Al3+, modulated these interactions; an increasing ion valence induced a transition from repulsive to attractive force, primarily owing to electrostatic screening, which caused conformational collapse of the PAA chains and diminished the range of steric repulsion. Similarly, increasing the concentration of these metal ions decreased the range of repulsive forces, eventually resulting in a net attraction driven by the same electrostatic and polymer conformation mechanisms. Notably, the addition of 0.1 M AlCl3 produced an anomalous long-range attraction between surfaces that could not be explained by conventional mechanisms, such as polymer bridging or electrostatic interactions between charge domains. en-copyright= kn-copyright= en-aut-name=KishimotoNaoto en-aut-sei=Kishimoto en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KajiRyota en-aut-sei=Kaji en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaKatsumi en-aut-sei=Tsuchiya en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImamuraKoreyoshi en-aut-sei=Imamura en-aut-mei=Koreyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshidaNaoyuki en-aut-sei=Ishida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=3 en-affil=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Science and Engineering, Doshisha University kn-affil= en-keyword=Interaction force kn-keyword=Interaction force en-keyword=Alumina surface kn-keyword=Alumina surface en-keyword=Anionic polyelectrolyte kn-keyword=Anionic polyelectrolyte en-keyword=Coexisting electrolyte kn-keyword=Coexisting electrolyte en-keyword=Atomic force microscopy kn-keyword=Atomic force microscopy END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=9 article-no= start-page=251152 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On weapons allometry and the form of sexual selection en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study of trait scaling with body size (allometry) has a long history, and it has been argued that positive static allometry is an indicator of directional sexual selection. However, a range of allometries exists for sexually selected traits, and modelling shows this variation can be generated by altering the form of selection (fitness functions) on the trait and/or body size. Interestingly, in all models, positive allometry appears to emerge only when there is directional selection on trait size. Here, we report on a sexually selected trait that shows strong positive static allometry and yet appears to be under stabilizing selection. This surprising finding suggests the evolution of trait scaling is even more nuanced than currently appreciated. en-copyright= kn-copyright= en-aut-name=ShinoharaHironori en-aut-sei=Shinohara en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SharmaManmohan D. en-aut-sei=Sharma en-aut-mei=Manmohan D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PennellTanya M. en-aut-sei=Pennell en-aut-mei=Tanya M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HoskenDavid J. en-aut-sei=Hosken en-aut-mei=David J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= affil-num=2 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= affil-num=3 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= en-keyword=inbreeding kn-keyword=inbreeding en-keyword=selection kn-keyword=selection en-keyword=beetle kn-keyword=beetle en-keyword=Gnatocerus kn-keyword=Gnatocerus END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=399 end-page=404 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Epstein-Barr Virus-Associated Early Gastric Carcinoma with Lymphoid Stroma Mimicking a Submucosal Tumor: A Typical Case Diagnosed by Endoscopic Resection and Treated by Local Resection with Sentinel Node Navigation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastric cancer with lymphoid stroma (GCLS) accounts for 1%-7% of gastric cancers; ~80% are Epstein-Barr virus (EBV)-positive. The rate of lymph node metastasis is relatively low, even when an early GCLS has invaded the submucosa. We report an early GCLS with massive submucosal invasion mimicking a submucosal tumor (SMT), diagnosed by endoscopic submucosal resection (ESD) and treated with local resection and sentinel node navigation surgery (SNNS). The patient was a 40-year-old Japanese man. A protruding lesion on the greater curvature of the middle part of his stomach was detected by X-ray, and an endoscopic examination revealed a 2.5-cm protruding tumor covered with a normal mucosa and small ulcers at the apex. ESD was performed for a diagnosis. The pathological diagnosis was lymphoepithelioma-like gastric cancer (GCLS), pT1b(SM2), Ly0, V0, pHM1, pVM1. EBV infection in the cancer cells was confirmed pathologically by EBV-encoded RNA. The local resection was performed using SNNS. The patient has had no recurrence or post-gastrectomy syndrome 4 years postsurgery. EBV-associated early GCLS resembling an SMT is relatively rare, and clinicians need to be aware of this disease. Local resection using SNNS may be a surgical option for GCLS cases with a low rate of lymphatic metastasis. en-copyright= kn-copyright= en-aut-name=IsozakiHiroshi en-aut-sei=Isozaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoSasau en-aut-sei=Matsumoto en-aut-mei=Sasau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakamaTakehiro en-aut-sei=Takama en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IsozakiYuka en-aut-sei=Isozaki en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiShigeki en-aut-sei=Murakami en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Oomoto Hospital kn-affil= en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=gastric cancer with lymphoid stroma kn-keyword=gastric cancer with lymphoid stroma en-keyword=lymphoepithelioma-like carcinoma kn-keyword=lymphoepithelioma-like carcinoma en-keyword=Epstein Barr virus kn-keyword=Epstein Barr virus en-keyword=sentinel node navigation surgery kn-keyword=sentinel node navigation surgery END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=393 end-page=398 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gastroduodenal Artery-Preserving Pancreatoduodenectomy after Esophagectomy with Gastric Conduit Reconstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatoduodenectomy (PD) after esophagectomy with gastric conduit reconstruction is technically challenging. Preserving the blood supply of the gastric conduit is crucial in performing PD after esophagectomy. We report the case of a 66-year-old man who underwent gastroduodenal artery-preserving PD after esophagectomy with gastric conduit reconstruction for intraductal papillary mucinous neoplasm. The patient developed pseudoaneurysm rupture postoperatively, but was successfully treated with interventional radiology. Precise assessment is important in developing a surgical strategy depending on the patient’s specific anatomy and tumor characteristics. Moreover, special attention should be paid to avoid accidental injuries of the gastric conduit and gastric vessels during surgery. en-copyright= kn-copyright= en-aut-name=MasunagaAkari en-aut-sei=Masunaga en-aut-mei=Akari 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=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo 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=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu 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=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SotaYumi en-aut-sei=Sota en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, 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= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=pancreatoduodenectomy kn-keyword=pancreatoduodenectomy en-keyword=esophagectomy kn-keyword=esophagectomy en-keyword=gastric conduit kn-keyword=gastric conduit en-keyword=fluorescence imaging kn-keyword=fluorescence imaging END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=387 end-page=392 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Utility of a Preoperative 3D Imaging Analysis System for Trigonal Meningioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trigonal meningiomas are rare and pose surgical challenges due to their deep location and proximity to critical neuroanatomical structures.

Dimension reduction via uniform manifold approximation and projection, followed by K-means++ clustering, was used to categorize 362 community-dwelling participants (mean age, 56.2 years; 54.9% women) into three groups: Low BP and Low HR (Lo-BP/Lo-HR), High BP and High HR (Hi-BP/Hi-HR), and Low BP and High HR (Lo-BP/Hi-HR). Cerebral vessel lesions were defined as the presence of at least one of the following magnetic resonance imaging findings: lacunar infarcts, white matter hyperintensities, cerebral microbleeds, or intracranial artery stenosis. A high urinary albumin-to-creatinine ratio (UACR) was defined as the top 10% (? 12 mg/g) of the mean value from ?2 measurements. Poisson regression with robust error variance, adjusted for demographics, lifestyle, and medical history, showed that the Hi-BP/Hi-HR group had relative risks of 3.62 (95% confidence interval, 1.75-7.46) for cerebral vessel lesions and 3.58 (1.33-9.67) for high UACR, and the Lo-BP/Hi-HR group had a relative risk of 3.09 (1.12-8.57) for high UACR, compared with the Lo-BP/Lo-HR group. These findings demonstrate the utility of an unsupervised, data-driven approach for identifying physiological patterns associated with subclinical target organ damage. en-copyright= kn-copyright= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MunetomoSosuke en-aut-sei=Munetomo en-aut-mei=Sosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniguchiKaori en-aut-sei=Taniguchi en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakahataNoriko en-aut-sei=Nakahata en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Environmental Medicine and Public Health, Izumo, Shimane University Faculty of Medicine kn-affil= affil-num=7 en-affil=Department of Health and Nutrition, The University of Shimane Faculty of Nursing and Nutrition kn-affil= affil-num=8 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=blood pressure kn-keyword=blood pressure en-keyword=heart rate kn-keyword=heart rate en-keyword=subclinical disease kn-keyword=subclinical disease en-keyword=uniform manifold approximation and projection kn-keyword=uniform manifold approximation and projection en-keyword=unsupervised machine learning kn-keyword=unsupervised machine learning END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=359 end-page=368 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Advantages of Single-Position Surgery over Posterior Fusion for Single-Level Degenerative Lumbar Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Single-position surgery with lateral lumbar interbody fusion (LLIF) and percutaneous pedicle screws (PPSs) is gaining attention for its reduced invasiveness. We developed SPAPS, a technique allowing two surgeons to perform anterior LLIF and posterior PPS insertion simultaneously in a single lateral decubitus position. This retrospective study compared SPAPS (SPAPS-LLIF, Group SL) and minimally invasive posterior/transforaminal lumbar interbody fusion (MIS-PLIF/TLIF, Group PT) in patients treated between 2016 and 2019 with a two-year follow-up. Operative time, estimated blood loss (EBL), length of hospital stay (LOS), JOABPEQ and VAS scores, segmental lordotic angle, lumbar lordotic angle, segmental Cobb’s angle, PPS misplacement, PPS loosening, fusion status, and muscle cross-sectional areas were compared. Fifty-two patients were analyzed (Group SL: 25; Group PT: 27). SPAPS significantly reduced operative time (118.0 vs. 165.3 min, p <0.01) and estimated blood loss (8.6 vs. 164.1 mL, p<0.01). While clinical outcomes and hospital stay were comparable, Group SL had significantly lower PPS loosening (0% vs. 13%, p<0.01) and non-union rates (0% vs. 22.2%, p=0.02). Multifidus muscle atrophy was also less in Group SL (?14.3 vs. ?121.5 mm2, p<0.01). SPAPS demonstrated advantages in reducing surgical invasiveness without compromising clinical efficacy, offering a promising alternative to conventional posterior fusion surgery. en-copyright= kn-copyright= en-aut-name=HiroseTomohiko en-aut-sei=Hirose en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkumaHisanori en-aut-sei=Ikuma en-aut-mei=Hisanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaKazutoshi en-aut-sei=Otsuka en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawasakiKeisuke en-aut-sei=Kawasaki en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Otsuka Orthopedic Clinic kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= en-keyword=single-position surgery kn-keyword=single-position surgery en-keyword=simultaneous kn-keyword=simultaneous en-keyword=lateral decubitus positioning kn-keyword=lateral decubitus positioning en-keyword=lateral lumbar interbody fusion kn-keyword=lateral lumbar interbody fusion en-keyword=posterior lumbar interbody fusion kn-keyword=posterior lumbar interbody fusion END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=353 end-page=358 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Extraocular Muscles in Patients with Exotropia and Healthy Participants Using Anterior Segment Optical Coherence Tomography en-subtitle= kn-subtitle= en-abstract= kn-abstract=To analyze and characterize the medial and lateral rectus muscles in patients with exotropia using anterior segment optical coherence tomography (AS-OCT). This study included 24 patients with exotropia (48 eyes) and 25 healthy individuals (50 eyes). Anterior segment optical coherence tomography was used to construct the en face images. The anterior chamber angle to the extraocular muscle insertion distance, muscle width, and muscle fiber angle from the muscle insertion sites were compared between the exotropia and the control groups. The correlation between these parameters and age or angle of deviation was evaluated. The mean ages were 13.2±4.1 years for the exotropia group and 17.6±7.2 years for the control group. The lateral rectus angle was significantly more inwardly rotated in the exotropia group than in the control group (1.6±6.3°, ?1.4±4.0°, p=0.014). With increasing angle of deviation, the width of the lateral rectus increased (p=0.002). Our results indicate that the lateral rectus angle is significantly more inwardly rotated in patients with exotropia. These findings should contribute to a deeper understanding of the extraocular muscles in patients with this condition. en-copyright= kn-copyright= en-aut-name=ChiharaYuki en-aut-sei=Chihara en-aut-mei=Yuki 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=ShibataKiyo en-aut-sei=Shibata en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KonoReika en-aut-sei=Kono en-aut-mei=Reika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanenagaKeisuke en-aut-sei=Kanenaga en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=exotropia kn-keyword=exotropia en-keyword=AS-OCT kn-keyword=AS-OCT en-keyword=anterior chamber angle to extraocular muscle insertion distance kn-keyword=anterior chamber angle to extraocular muscle insertion distance en-keyword=muscle width kn-keyword=muscle width en-keyword=muscle fiber angle kn-keyword=muscle fiber angle END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=345 end-page=352 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Inhibition of Air-Exposure Stress?Induced Autolysis in Clostridium perfringens by Zn2+ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clostridium perfringens is a pathogenic anaerobe that causes gas gangrene and food poisoning. Although autolysin-mediated reorganization of the bacterial cell wall is crucial for cell division, excessive autolysin activity induced by stressors can lead to cell lysis. In C. perfringens, air exposure is a significant stressor that causes cell lysis, and Acp (N-acetylglucosaminidase) is known to be a major autolysin. To further facilitate C. perfringens research, a technology to prevent air-induced cell lysis must be developed. This study investigated the role of Acp in air-induced autolysis and explored potential inhibitors that would prevent cell lysis during experimental procedures. Morphological analyses confirmed that Acp functions as an autolysin in C. perfringens, as acpdeficient strains exhibited filamentous growth. The mutants exhibited negligible autolysis under air-exposure stress, confirming the involvement of Acp in the autolytic process. We also evaluated the effects of various divalent cations on Acp activity in vitro and identified Zn2+ as a potent inhibitor. Brief treatment with a Zn2+- containing buffer induced dose-dependent cell elongation and autolysis inhibition in C. perfringens. These findings demonstrate that simple Zn2+ treatment before experiments stabilizes C. perfringens cells, reducing autolysis under aerobic conditions and facilitating various biological studies, except morphological analyses. en-copyright= kn-copyright= en-aut-name=MatsunagaNozomu en-aut-sei=Matsunaga en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EgusaSeira en-aut-sei=Egusa en-aut-mei=Seira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AonoRiyo en-aut-sei=Aono en-aut-mei=Riyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamaiEiji en-aut-sei=Tamai en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HitusmotoYasuo en-aut-sei=Hitusmoto en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaSeiichi en-aut-sei=Katayama en-aut-mei=Seiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=2 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=3 en-affil=Department of Medical Technology, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=4 en-affil=Department of Infectious Disease, College of Pharmaceutical Science, Matsuyama University kn-affil= affil-num=5 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=6 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= en-keyword=Clostridium perfringens kn-keyword=Clostridium perfringens en-keyword=autolysin kn-keyword=autolysin en-keyword=zinc kn-keyword=zinc en-keyword=air-exposure autolysis kn-keyword=air-exposure autolysis END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=339 end-page=343 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Scleral Adjustment Method: A Novel Adjustable Suture Technique in Strabismus Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine whether passing a pole suture through the sclera at two points provides fixation comparable to that of a sliding noose, we measured the tensile strength of the suture?sclera interface during simulated traction. In this in vitro study, three suture patterns were evaluated in porcine eyeballs, using 6-0 polyglycolic acid sutures. Patterns A (control), B (second suture pass perpendicular), and C (second suture pass in the same direction) were compared. The tensile strength of each pattern was measured 20 times using a KANON TK300CN, and the results were analyzed using the Kruskal?Wallis test. Pattern A showed a tensile strength of 2±4 gram-force (gf) (range: 0-12). Pattern B showed 112±38 gf (range: 61-184). Pattern C showed 139±31 gf (range: 97-204). Patterns B and C had significantly higher tensile strengths than Pattern A (p<0.001). Although Pattern C was not significantly different from Pattern B (p=0.363), it exhibited the highest tensile strength. Lifting the suture between the first and second suture passes allows for an adjustable suture length, suggesting that adjustability can be achieved using only the sclera. This scleral adjustment method with a second suture pass offers a durable means of securing extraocular muscles and may represent a valuable addition to adjustable suturing techniques. en-copyright= kn-copyright= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=Lino Eye Clinic kn-affil= affil-num=2 en-affil=Lino Eye Clinic kn-affil= en-keyword=scleral adjustment method kn-keyword=scleral adjustment method en-keyword=adjustable suture technique kn-keyword=adjustable suture technique en-keyword=hang-loose method kn-keyword=hang-loose method en-keyword=tensile strength kn-keyword=tensile strength en-keyword=polyglycolic acid sutures kn-keyword=polyglycolic acid sutures END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=329 end-page=337 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current Status of Extracorporeal Membrane Oxygenation as a Treatment Strategy for Primary Graft Dysfunction after Lung Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary graft dysfunction (PGD) is one of the major risk factors affecting patients’ short- and long-term survival after lung transplantation. No particular management strategy has been established for PGD; supportive care is the mainstay of PGD treatment. When a supportive strategy fails, the patient may require the introduction of extracorporeal membrane oxygenation (ECMO) as the last-resort measure for severe PGD. A variety of study of ECMO as a PGD treatment was reported and the management of PGD patients developed so far. Early recognition of a patient’s need for ECMO and its prompt initiation are critical to improved outcomes. The use of venovenous-ECMO became the preferred procedure for PGD rather than venoarterial-ECMO. However, the current ECMO strategy has limitations, and using ECMO to manage patients with PGD is not sufficiently effective. Further studies are required to develop this promising technology. en-copyright= kn-copyright= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital 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= en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=primary graft dysfunction kn-keyword=primary graft dysfunction en-keyword=extracorporeal membrane oxygenation kn-keyword=extracorporeal membrane oxygenation en-keyword=ex vivo lung perfusion kn-keyword=ex vivo lung perfusion END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=321 end-page=328 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Review of the Endoscopic Treatment for Bile Leak Following Cholecystectomy and Hepatic Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bile leak occurs in 2-25% of liver transplant, 3-27% of hepatic resection, and 0.1-4% of cholecystectomy cases. The clinical course of bile leak varies depending on the type of surgery that caused the fistula, as well as the type, severity, and timing of bile duct injury. Although infections resulting from bile leak can be life-threatening, the introduction of endoscopic treatment has enabled some patients to avoid reoperation and has reduced the negative impact on quality of life associated with external fistulas for percutaneous drainage. Endoscopic interventions, such as sphincterotomy and stent placement, reduce the pressure gradient between the bile duct and duodenum, facilitating bile drainage through the papilla and promoting the closure of the leak. We reviewed the literature from 2004 to 2024 regarding bile leak following cholecystectomy and liver surgery, examining recommended techniques, timing, and treatment outcomes. In cases of bile leak following cholecystectomy, clinical success was achieved in 72-96% of cases, while success rates for bile leak following liver surgery ranged from 50% to 100%. Although endoscopic treatment is effective, it is not universally applicable, and its limitations must be carefully considered. en-copyright= kn-copyright= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=bile leak kn-keyword=bile leak en-keyword=cholecystectomy kn-keyword=cholecystectomy en-keyword=hepatic surgery kn-keyword=hepatic surgery en-keyword=endoscopic retrograde cholangiography kn-keyword=endoscopic retrograde cholangiography en-keyword=bridging stent placement kn-keyword=bridging stent placement END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=17 article-no= start-page=6102 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors for Perioperative Urinary Tract Infection After Living Donor Kidney Transplantation Characterized by High Prevalence of Desensitization Therapy: A Single-Center Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Limited research exists on risk factors for urinary tract infections (UTIs) in kidney transplant recipients, particularly in high-risk groups such as ABO-incompatible or donor-specific antibody (DSA)-positive cases. Early UTIs, especially within the first month post-transplant, impact on acute rejection and long-term graft outcomes, highlighting the need for risk factor identification and management. Methods: Among 157 living donor kidney transplant cases performed at our institution between 2009 and 2024, 128 patients were included after excluding cases with >72 h of perioperative prophylactic antibiotics or urological complications. UTI was defined as the presence of pyuria and a positive urine culture, accompanied by clinical symptoms requiring antibiotic treatment, occurring within one month post-transplantation. Results: The median onset of UTI was postoperative day 8 (interquartile range, IQR: 6.8?9.3). No subsequent acute rejection episodes were observed. The median serum creatinine at 1 month postoperatively was 1.3 mg/dL (IQR: 1.1?1.7), and this was not significantly different from those who did not develop UTI. In univariate analysis, low or high BMI (<20 or >25), longer dialysis duration (>2.5 years), desensitization therapy (plasmapheresis + rituximab), elevated preoperative neutrophil-to-lymphocyte ratio (NLR) (?3), and longer warm ischemic time (WIT) (?7.8 min) were significantly associated with an increased infection risk of UTI (p = 0.010, 0.036, 0.028, 0.015, and 0.038, respectively). Multivariate analyses revealed that abnormal BMI, longer dialysis duration, desensitization therapy, and longer WIT were independent risk factors for UTI (p = 0.012, 0.031, 0.008, and 0.033, respectively). The incidence of UTI increased with the number of risk factors: 0% (0/16) for zero, 10% (5/48) for one, 31% (16/51) for two, 45% (5/11) for three, and 100% (2/2) for four risk factors. Conclusions: Desensitization therapy, BMI, dialysis duration, and WIT were identified as independent risk factors for perioperative UTI. In patients with risk factors, additional preventive strategies should be considered, with extended antibiotic prophylaxis being one potential option. en-copyright= kn-copyright=
