In this context, studies into the effective operation of machine learning systems in real-world environments have become essential. In actual operational settings, the distribution of input data often changes over time, leading to a significant decline in the predictive performance of models. Additionally, the lack of ground-truth data for test data during operation can sometimes make adaptation through retraining difficult. This study proposes a framework that autonomously adapts to changes in input data distribution, even in environments where ground-truth data for test data is unavailable during operation. This framework analyzes the distribution of input data and selects the appropriate predictive model based on the state of the distribution. To ensure optimal model selection, the framework employs two complementary approaches: 1) dynamically switching between multiple pre-trained models with different feature sets according to environmental changes and 2) building ensemble models based on the distribution of the test data. These approaches enable the framework to autonomously adapt to shifts in data distribution, even in operational settings where ground-truth data is unavailable. Evaluation experiments using both simulated and real-world data assessed the predictive performance of the proposed method through metrics such as R2, RMSE, and MAE. Compared to conventional single model predictions, the proposed method consistently demonstrated higher accuracy. These results indicate that the proposed approach effectively adapts to data distribution shifts in operational environments where ground-truth data is unavailable. en-copyright= kn-copyright= en-aut-name=FurukawaKento en-aut-sei=Furukawa en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaHiroyuki en-aut-sei=Nakagawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaTatsuhiro en-aut-sei=Tsuchiya en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Information Science and Technology, Osaka 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 Information Science and Technology, Osaka University kn-affil= en-keyword=Self-adaptive systems kn-keyword=Self-adaptive systems en-keyword=frameworks kn-keyword=frameworks en-keyword=machine learning kn-keyword=machine learning END start-ver=1.4 cd-journal=joma no-vol=135 cd-vols= no-issue= article-no= start-page=103134 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regulation of brain-specific kinases 1 and 2 (BRSK1/2) by Ca2+/calmodulin en-subtitle= kn-subtitle= en-abstract= kn-abstract=We conducted a genome-wide calmodulin (CaM) interaction screening of 462 GST-fused human protein kinases to identify novel CaM-dependent protein kinases (CaMKs). In addition to known CaMKs, including myosin light chain kinases, CaMK2γ, and death-associated kinase 2, we identified the brain-specific protein kinase 2 (BRSK2, also known as SAD-A) as a novel CaM interactant. Proximity biotinylation and CaM?sepharose chromatography assays revealed that rat BRSK isoforms (BRSK1/2) interact with CaM in a Ca2+-dependent manner in vitro. We found that CaM suppresses the activation-loop phosphorylation of BRSK1 (at Thr189) and BRSK2 (at Thr175) by liver kinase B1 (LKB1), an activating kinase, in a Ca2+-dependent manner (IC50 of ?7 ?M), thereby inhibiting BRSK activation. LKB1-catalyzed phosphorylation of the catalytic domain mutant of BRSK1 (residues 1?294) at Thr189 was suppressed by the addition of Ca2+/CaM, consistent with direct CaM binding of the kinase domain, as well as wild-type BRSK1. We confirmed that the LKB1 activity was not directly suppressed by Ca2+/CaM, supporting the hypothesis that the direct interaction of Ca2+/CaM with the kinase domain blocks the phosphorylation/activation of BRSK1/2 by LKB1. The kinase activity and PP2Cα-catalyzed dephosphorylation of LKB1-phosphorylated BRSK1 were not altered by Ca2+/CaM, although it was demonstrated to bind to Ca2+/CaM like that of unphosphorylated BRSK1. This unrecognized mechanism of BRSK1/2 regulation, involving the direct role of Ca2+/CaM binding, which inhibits phosphorylation/activation by LKB1, may open a new Ca2+ signal transduction pathway in neurons. en-copyright= kn-copyright= en-aut-name=WashidaNaoyuki en-aut-sei=Washida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KataokaMoe en-aut-sei=Kataoka en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BrunAnna R. en-aut-sei=Brun en-aut-mei=Anna R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakezakiUryu en-aut-sei=Takezaki en-aut-mei=Uryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HijikawaKo en-aut-sei=Hijikawa en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamauchiHaruki en-aut-sei=Yamauchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhtsukaSatomi en-aut-sei=Ohtsuka en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MorishitaRyo en-aut-sei=Morishita en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TokumitsuHiroshi en-aut-sei=Tokumitsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=6 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=9 en-affil=CellFree Sciences Co., Ltd. kn-affil= affil-num=10 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=BRSK1 kn-keyword=BRSK1 en-keyword=BRSK2 kn-keyword=BRSK2 en-keyword=calmodulin kn-keyword=calmodulin en-keyword=LKB1 kn-keyword=LKB1 en-keyword=phosphorylation kn-keyword=phosphorylation en-keyword=Ca2+ kn-keyword=Ca2+ en-keyword=CaM-dependent protein kinase kn-keyword=CaM-dependent protein kinase END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue= article-no= start-page=1806 end-page=1810 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An electric field temporarily strengthens zirconia ceramics en-subtitle= kn-subtitle= en-abstract= kn-abstract=By applying an electric field to yttria-stabilized zirconia (8YSZ) equipped with an inert electrode, oxide ions are localized near the positive electrode, causing it to expand. When polarization was performed under different conditions, it was possible to strengthen the material to 1.5 times that of an untreated sample. The lattice constant of the positive electrode surface after polarization was larger than before polarization. When the Vickers hardness of the positive electrode surface was measured by changing the test load, the smaller the load, the higher the hardness value. Polarization caused oxide ions to move near the positive electrode, filling in the defects and generating an expanded layer with a large lattice constant. It is believed that this was subjected to compressive stress from the bulk layer, which had not changed in volume, resulting in an increase in strength. en-copyright= kn-copyright= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuTakahiro en-aut-sei=Shimizu en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyamaMitsuru en-aut-sei=Nishiyama en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Poling kn-keyword=Poling en-keyword=Zirconia ceramics kn-keyword=Zirconia ceramics en-keyword=Strengthening kn-keyword=Strengthening en-keyword=Internal stress kn-keyword=Internal stress END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=269 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From localized 4f electrons to anisotropic exchange interactions in ferromagnetic CeRh6Ge4 en-subtitle= kn-subtitle= en-abstract= kn-abstract=CeRh6Ge4 is a cerium-based ferromagnetic material exhibiting a quantum critical behavior under pressure. We derive effective exchange interactions, using the framework of density functional theory combined with dynamical mean-field theory. Our results reveal that the nearest-neighbor ferromagnetic interaction along the c axis is isotropic in spin space, leading to a formation of spin chains. On the other hand, the inter-chain coupling is highly anisotropic: The in-plane moment weakly interacts ferromagnetically in the a?b plane to stabilize the ferromagnetic state, whereas the z-component couples antiferromagnetically, contributing to its destabilization. The magnetic anisotropy of the interchain interactions as well as of the local 4f wavefunctions characterizes the magnetic properties underlying the ferromagnetic transition and the quantum critical behavior in CeRh6Ge4. en-copyright= kn-copyright= en-aut-name=ItokazuShoichiro en-aut-sei=Itokazu en-aut-mei=Shoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KirikoshiAkimitsu en-aut-sei=Kirikoshi en-aut-mei=Akimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JeschkeHarald O. en-aut-sei=Jeschke en-aut-mei=Harald O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukiJunya en-aut-sei=Otsuki en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3-4 article-no= start-page=438 end-page=410 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=A Study on Water Pollution by Persistent Organic Pollutants（PFOS・PFOA）: Focused on Duty of Care in Transactions. kn-title=PFOS・PFOA 等の残留性有機汚染物質による水質汚染に関する一考察 ― 取引上の義務の視点から― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TsujiH. en-aut-sei=Tsuji en-aut-mei=H. kn-aut-name=辻博明 kn-aut-sei=辻 kn-aut-mei=博明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学名誉教授 END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3-4 article-no= start-page=586 end-page=496 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=The Possibility of a Japanese Approach to Standards of Judicial Review kn-title=日本独自の違憲審査基準論の可能性 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=ItoT. en-aut-sei=Ito en-aut-mei=T. kn-aut-name=伊藤健 kn-aut-sei=伊藤 kn-aut-mei=健 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3-4 article-no= start-page=706 end-page=657 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=The Development and Present State of Judicial Doctrine on the Speedy Trial Clause kn-title=迅速裁判条項に関する判例法理の展開と現状 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HaradaK. en-aut-sei=Harada en-aut-mei=K. kn-aut-name=原田和往 kn-aut-sei=原田 kn-aut-mei=和往 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3-4 article-no= start-page=726 end-page=707 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=A Study on the Consequences of Invalid Election Results under Article 251 of the Public Offices Election Act kn-title=公職選挙法251条（当選人本人の選挙犯罪）による当選無効の結果に関する一考察 ― 最三小判令和５年12月12日民集77巻９号2229頁を契機として― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FukushigeS. en-aut-sei=Fukushige en-aut-mei=S. kn-aut-name=福重さと子 kn-aut-sei=福重 kn-aut-mei=さと子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3-4 article-no= start-page=371 end-page=407 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=On F.

However, many challenges to its implementation have been identified in school settings, including teachers’ excessive workload and insufficient organizational support systems. Moreover, the support provided by school counselors (SCs) has not yet been sufficiently developed. Therefore, this study examined the potential for expanding SCs’ support in developmentally supportive student guidance by reviewing its current status and challenges. Furthermore, through a reanalysis of a practical case using the Planning Sheet (Hara et al., 2024), the study explored the usefulness of this framework in enabling SCs and schools to share educational goals and collaboratively plan their support activities. kn-abstract=　2022年に改訂された「生徒指導提要」では，すべての児童生徒の成長を支援する発達支持的生徒指導の重要性が明確に示されている。しかし，その定着には，教員の多忙化や組織的支援体制の不十分さなど，学校現場における多くの課題が指摘されている。さらに，スクールカウンセラー（SC）による支援も十分に展開されているとは言い難い。そこで本稿では，発達支持的生徒指導におけるSCの支援の拡充可能性を検討するため，現状と課題を整理した。また，プランニングシートを活用した実践事例（原他, 2024）の再分析を通して，SCと学校が教育目標を共有しながら協働的に支援を計画する枠組みの有用性を吟味した。 en-copyright= kn-copyright= en-aut-name=HARANoriyuki en-aut-sei=HARA en-aut-mei=Noriyuki kn-aut-name=原範幸 kn-aut-sei=原 kn-aut-mei=範幸 aut-affil-num=1 ORCID= en-aut-name=MISAWARyo en-aut-sei=MISAWA en-aut-mei=Ryo kn-aut-name=三沢良 kn-aut-sei=三沢 kn-aut-mei=良 aut-affil-num=2 ORCID= en-aut-name=AOKITazuko en-aut-sei=AOKI en-aut-mei=Tazuko kn-aut-name=青木多寿子 kn-aut-sei=青木 kn-aut-mei=多寿子 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山県公立学校スクールカウンセラー affil-num=2 en-affil= kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil= kn-affil=岡山大学学術研究院教育学域 en-keyword=発達支持的生徒指導 (developmentally supportive student guidance) kn-keyword=発達支持的生徒指導 (developmentally supportive student guidance) en-keyword=プランニングシート (Planning Sheet) kn-keyword=プランニングシート (Planning Sheet) en-keyword=スクールカウンセラー (school counselor) kn-keyword=スクールカウンセラー (school counselor) en-keyword=チーム学校 (school as a team) kn-keyword=チーム学校 (school as a team) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=237 end-page=251 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preliminary Consideration on the Introduction of Philosophical Thinking into Special Needs Education: A Methodological Framework Based on the Concepts of Duration, Becoming, and Diffraction kn-title=特別支援教育への哲学的思考導入についての予備的考察 持続・生成変化・回折の考え方に基づく方法的枠組みの試案 en-subtitle= kn-subtitle= en-abstract=This paper presents a theoretical and methodological examination aimed at introducing philosophical thinking into the practice of special needs education in response to contemporary challenges in the field. As its theoretical foundation, the study outlines Bergson’ s theory of memory, Deleuze and Guattari’ s philosophy of becoming, Barad’ s diffractive methodology, and Blom’ s diffractive ethnography. Building upon these theories, it proposes a methodological framework that adopts three interrelated analytical perspectives?“material-discursive practices,” “duration,” and “becoming”?for reading and interpreting educational practices. These perspectives, situated within the paradigm of post-qualitative research, make it possible to understand educational events as relational and processual phenomena rather than fixed outcomes. Future issues include the theoretical integration of the three lenses, clarification of the distinctions between diffractive methodology and diffractive ethnography, and refinement of analytical methods for connecting multiple practice episodes. kn-abstract=　本稿は，現代の特別支援教育の課題から，特別支援教育実践に哲学的思考を導入するための理論的・方法的検討を行うものである。まず，理論基盤として，ベルクソンの「記憶理論」，ドゥルーズ＆ガタリの「生成変化の哲学」，Baradの「回折的方法論」，Blomの「回折的エスノグラフィー」について概説した。そして，理論基盤を基に方法的枠組みとして，「物質−言説的実践」，「持続」，「生成変化」の三つの視点を教育実践を読み解くための相互補完的な分析視点として採用することを提案した。これらの視点は，ポスト質的研究として，出来事を関係的・過程的に捉えることを可能にするものである。今後の課題として，三つのレンズ間の理論的整理，回折的方法論と回折的エスノグラフィーの差異化，および複数の実践エピソードを接続して描くための分析手法の精緻化が挙げられた。 en-copyright= kn-copyright= en-aut-name=HAMADAYo en-aut-sei=HAMADA en-aut-mei=Yo kn-aut-name=M田曜 kn-aut-sei=M田 kn-aut-mei=曜 aut-affil-num=1 ORCID= en-aut-name=TAKANOMiyuki en-aut-sei=TAKANO en-aut-mei=Miyuki kn-aut-name=野美由紀 kn-aut-sei=野 kn-aut-mei=美由紀 aut-affil-num=2 ORCID= en-aut-name=SATOSatoru en-aut-sei=SATO en-aut-mei=Satoru kn-aut-name=佐藤曉 kn-aut-sei=佐藤 kn-aut-mei=曉 aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama Prefectural Okayama Seto Special Needs School kn-affil=岡山県立岡山瀬戸高等支援学校 affil-num=2 en-affil=Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=特別支援教育 (special needs education) kn-keyword=特別支援教育 (special needs education) en-keyword=哲学 (philosophy) kn-keyword=哲学 (philosophy) en-keyword=分析視点 (analytical perspectives) kn-keyword=分析視点 (analytical perspectives) en-keyword=ポストヒューマニズム (posthumanism) kn-keyword=ポストヒューマニズム (posthumanism) en-keyword=質的研究 (qualitative research) kn-keyword=質的研究 (qualitative research) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=221 end-page=235 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Designing an Educational Model and Assessing Outcomes for the Graduate Course “Leadership and SDGs” New Directions in Leadership Education through Theory Learning, Peer Review, and Reflective Practice kn-title=大学院共通科目『リーダーシップとSDGs』の教育モデル構築と成果分析 理論学習・ピアレビュー・省察活動によるリーダーシップ教育の新展開 en-subtitle= kn-subtitle= en-abstract=Okayama University's graduate school has developed and implemented a core course, “Leadership and SDGs,” to foster leadership among graduate students.

It took place at a public upper secondary school for students with mild intellectual disabilities. A “Thank-You Campaign” was conducted with 24 students in one grade level. The frequency of predefined target behaviors was analyzed using AB design with follow-ups. A social validity questionnaire was also administered to six teachers of the same grade. Results showed that both the frequency of the target behaviors and the percentage of students engaging in those behaviors increased after the campaign. These increases remained above baseline levels for a certain period after the campaign ended. The intervention also demonstrated a moderate degree of social validity. These findings suggest that campaign-based approaches can be a useful form of Tier 1 support in SWPBS for students with mild intellectual disabilities at the upper secondary level. kn-abstract=　本研究は，軽度知的障害のある後期中等教育段階の公立知的障害高等特別支援学校において，SWPBS 第1層支援としてキャンペーン方式の支援を実施し，その効果検証を行った。方法としては，Ｘ学年生徒24名に対して挨拶行動の促進を狙ったキャンペーンを実施し，目標行動の生起数についてABフォローアップデザインを用いて検討した。また，Ｘ学年教員6名に対し，社会的妥当性を評価するアンケートを実施した。その結果，キャンペーンの介入直後に目標行動の生起数および目標行動に従事した生徒の割合の増加が見られ，キャンペーン終了後もベースラインと比較した増加が一定期間確認された。また，一定程度の社会的妥当性も確認できた。 en-copyright= kn-copyright= en-aut-name=TOKIMITSUHideaki en-aut-sei=TOKIMITSU en-aut-mei=Hideaki kn-aut-name=時光秀明 kn-aut-sei=時光 kn-aut-mei=秀明 aut-affil-num=1 ORCID= en-aut-name=MIYAZAKIYoshio en-aut-sei=MIYAZAKI en-aut-mei=Yoshio kn-aut-name=宮ｱ善郎 kn-aut-sei=宮ｱ kn-aut-mei=善郎 aut-affil-num=2 ORCID= en-aut-name=KOYAMAMadoka en-aut-sei=KOYAMA en-aut-mei=Madoka kn-aut-name=小山円 kn-aut-sei=小山 kn-aut-mei=円 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Course), Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Kurashiki Kotoura Special Needs Seni or High School, Okayama Prefecture kn-affil=岡山県立倉敷琴浦高等支援学校 en-keyword=高等部 (High school division) kn-keyword=高等部 (High school division) en-keyword=軽度知的障害 (Mild intellectual disabilities) kn-keyword=軽度知的障害 (Mild intellectual disabilities) en-keyword=SWPBS（学校規模ポジティブ行動支援）(School-Wide Positive Behavior Support (SWPBS)) kn-keyword=SWPBS（学校規模ポジティブ行動支援）(School-Wide Positive Behavior Support (SWPBS)) en-keyword=第1層支援 (Tier 1 support) kn-keyword=第1層支援 (Tier 1 support) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=191 end-page=203 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Examining a Practical Case of Learning for Community Development ?Focusing on the Changes in Awareness of Junior High School Students During Integrated Studies? kn-title=町づくりを考える実践事例の検討 ―総合的な学習の時間を通じた中学生の意識変化に着目して― en-subtitle= kn-subtitle= en-abstract= This study aims to clarify the effects of junior high school students planning community development through collaboration and interaction with others, and the changes in learners that arise from the results of such practice.

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

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

(2025). In the lesson practice, details of the climate and seasonal cycle around Germany were firstly explained and the German lied “Im Fr?hling” (In spring) composed by F. Schubert was appreciated, paying attention to how the scenes and emotions expressed by the lyrics “all summer long” in the 3rd verse of this song might differ whether we imagine the climate around Germany or that around Japan. It seems that the present activity provided an opportunity for the students to perceive the climate environments and seasonal feelings quite different from those familiar to them . However, how to explore the appreciation activities that focus also on the musical expression itself of that song is an interesting remaining problem, in order for the students to capture the summer scenery and emotions which Schubert himself imagined. kn-abstract=　「異質な他者」への出会いを促す授業例の更なる蓄積のため，ドイツ付近の「夏」の気候と季節感に注目した教科横断的な授業を大学で実践した。授業では，ドイツ付近の気候と季節サイクルの中での「夏」の特徴を把握すると共に，シューベルトの歌曲《春に》を鑑賞した。《春に》の3 番の「夏の間じゅう，ずっと」という歌詞で歌われている情景や情感が，ドイツ付近と日本付近を想定した場合にどう違い得るか，に関する受講生の記述を分析した。その結果，日本の夏の高温多湿な環境からは原詩の情感そのものが成立し難いと感じた学生もいるなど，本実践は，自分たちの「当たり前」とは異なる気候や季節感にも目を向ける機会になり得たといえる。一方，日本とはかなり違う気候背景の中でシューベルトが思い描いたであろう情景・心情に授業で深く迫るための，音楽表現自体への踏み込み方についても，今後検討する必要性が示唆された。 en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=NAGAOKAIsao en-aut-sei=NAGAOKA en-aut-mei=Isao kn-aut-name=長岡功 kn-aut-sei=長岡 kn-aut-mei=功 aut-affil-num=2 ORCID= en-aut-name=KATOHaruko en-aut-sei=KATO en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Faculty of Education, Gufu Shotoku Gakuen University (Former affiliation) kn-affil=元　岐阜聖徳学園大学教育学部 en-keyword=気候と音楽 kn-keyword=気候と音楽 en-keyword=ドイツ付近の夏の気候と季節感 kn-keyword=ドイツ付近の夏の気候と季節感 en-keyword=気候と文化理解の学際的ESD教師教育 kn-keyword=気候と文化理解の学際的ESD教師教育 en-keyword=異質な他者への理解 kn-keyword=異質な他者への理解 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=61 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on Physical Activity Levels During Soccer Matches Among Junior High School Students Focusing on Position and Physical/Fitness Characteristics kn-title=中学生を対象としたサッカー試合中の身体活動量に関する研究 〜ポジションと身体・体力特性に着目して〜 en-subtitle= kn-subtitle= en-abstract=We compared physical and fitness characteristics by soccer position using results from the New Physical Fitness Test administered to 30 junior high school students.

However, significant differences were observed between positions in step count and the proportion of time spent in physical activity by intensity level. This revealed that physical activity levels during soccer matches differ between positions even among junior high school students, clarifying position-specific characteristics in soccer.

Participants were 85 children (41 boys, 44 girls). Step counts and time spent in different activity intensities were evaluated during recess, physical education (PE) classes, and the whole school day. Results showed that children with higher fitness levels tended to have greater step counts and more moderate-to-vigorous physical activity (MVPA) during recess. Significant differences were found in morning recess for boys and in lunch recess and PE classes for girls. The proportion of MVPA was 11.3% during recess and 15.7% during PE classes, which was lower than that reported in other countries and did not meet international recommendations. This study provides fundamental data on physical activity in elementary school settings and suggests the importance of enhancing opportunities for physical activity, parti cularly during recess and PE classes. kn-abstract=　本研究の目的は，小学校6年生の学校生活における活動場面別の身体活動量を加速度計を用いて客観的に測定し，その体力との関係を検討することである．対象は小学校児童85名(男子41名，女子44名)とし，休み時間，体育授業，学校生活全体における歩数と強度別活動時間を評価した．その結果，男女ともに体力上位群は休み時間において歩数とMVPAが多い傾向が示され，特に男子は中休み，女子は昼休みおよび体育授業で有意差が認められた．各活動場面のMVPA が占める割合は休み時間11.3％，体育授業15.7％であり，諸外国と比較して少なく，国際的推奨値にも届かなかった．本研究は，小学校における身体活動量の基礎データを提示するとともに，学校生活，特に休み時間や体育授業における身体活動機会の充実が必要であることを示唆した． en-copyright= kn-copyright= en-aut-name=YASUNOBEJin en-aut-sei=YASUNOBE en-aut-mei=Jin kn-aut-name=安延仁 kn-aut-sei=安延 kn-aut-mei=仁 aut-affil-num=1 ORCID= en-aut-name=SASAYAMAKensaku en-aut-sei=SASAYAMA en-aut-mei=Kensaku kn-aut-name=笹山健作 kn-aut-sei=笹山 kn-aut-mei=健作 aut-affil-num=2 ORCID= en-aut-name=ADACHIMinoru en-aut-sei=ADACHI en-aut-mei=Minoru kn-aut-name=足立稔 kn-aut-sei=足立 kn-aut-mei=稔 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Mie University kn-affil=三重大学教育学部 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=加速度計 (accelerometer) kn-keyword=加速度計 (accelerometer) en-keyword=身体活動量 (physical activity) kn-keyword=身体活動量 (physical activity) en-keyword=体力 (physical fitness) kn-keyword=体力 (physical fitness) en-keyword=小学校児童 (elementary school children) kn-keyword=小学校児童 (elementary school children) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=31 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of Factors Contributing to Confusion Regarding Left-Right Understanding of Convex Lens Images ?Proposals for Inquiry-Based Learning Based on Textbook Analysis and Teacher Questionnaire? kn-title=凸レンズの像の左右理解に関する混乱の要因分析 教科書分析と教員アンケートによる探究的な学びへの提案 en-subtitle= kn-subtitle= en-abstract=This study focused on the confusion students experience regarding the orientation of images during the learning of convex lens in junior high school.

The results revealed that while textbook descriptions have shifted toward specifying the observation location, teaching methods among teachers vary, causing confusion of students. To address these issues, a 3D-printed teaching material was developed that naturally fixes the observation viewpoint. Its effectiveness was examined through teacher training. This material was found to be effective in promoting students' intuitive understanding and bringing inquiry-based learning. kn-abstract=　本研究は、中学校理科の凸レンズ学習で生徒が像の向きに抱く混乱に着目した。その要因を、光源・スクリーン・観察場所といった実験条件が十分に意識されてこなかった点にあると考察し、学習指導要領と教科書の変遷分析、および現職教員へのアンケート調査を実施した。その結果、教科書の記述は観察場所を指定する方向へ変化しているものの、現場教員の指導法にはばらつきがあり、生徒の混乱を招く一因となっていることを明らかにした。これらの課題解決のため、観察視点を自然に固定できる3D プリンタ製教材を開発し、教員研修でその有効性を検討した。本教材は生徒の直感的理解を促し、探究的な学びを引き出す上で有効であることが示唆された。 en-copyright= kn-copyright= en-aut-name=TANIMOTOKunihiko en-aut-sei=TANIMOTO en-aut-mei=Kunihiko kn-aut-name=谷本薫彦 kn-aut-sei=谷本 kn-aut-mei=薫彦 aut-affil-num=1 ORCID= en-aut-name=INADAYoshihiko en-aut-sei=INADA en-aut-mei=Yoshihiko kn-aut-name=稲田佳彦 kn-aut-sei=稲田 kn-aut-mei=佳彦 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=凸レンズ (Convex lens) kn-keyword=凸レンズ (Convex lens) en-keyword=上下左右逆 (the orientation of images) kn-keyword=上下左右逆 (the orientation of images) en-keyword=教科書 (Textbooks) kn-keyword=教科書 (Textbooks) en-keyword=学習指導要領 (Course of Study) kn-keyword=学習指導要領 (Course of Study) en-keyword=３D プリンタ (3D printer) kn-keyword=３D プリンタ (3D printer) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=15 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Critical Reading Instruction of Expository Text that Promotes Reflecting: Practice for First-year Student at High School kn-title=説明的文章の指導における「内省」を促す批判的読み ―高等学校１年生を対象として― en-subtitle= kn-subtitle= en-abstract=　Critical reading is an essential skill at present time and is included in government guidelines for teaching. Although recent research on teaching critical reading has been conducted, there have been criticisms that lack of consideration of content value and understanding context within society. There are also calls for critical reading that focuses on the perspective of “reflect” . Therefore, this paper developed a lesson that encourages students not only critically read the text, but also critically consider (reflect on) their own ideas. As a measure to achieve this, incorporated activities such as comparing two teaching materials that contained multiple social perceptions, exchanging opinions from opposing perspectives, writing an evaluation of the materials, and having the students themselves evaluate their own writing (their own reading). Analysis of the students’ writings shows that, while some students didn’ t reach conscious reflection, about 60% of students’ writings showed changes. And then it suggests that the methods used were effective. kn-abstract=　批判的読みは，現代では欠かせない能力であり，学習指導要領にも明記されている。近年，批判的読みの指導に関する研究がなされているものの，内容的な価値の検討や社会的な文脈のなかで捉えることが希薄だとする指摘や，「反省性」という観点に着目した批判的読みを求める声もある。そこで，本稿では，文章そのものを批判的に読むだけでなく，自身の持っている考えをも批判的に捉える（内省する）ことを促す授業を開発した。その手立てとして，複数の社会認識が存在する二つの教材の読み比べたうえで，対立する立場からの意見交換を行うことや，教材に対する評価の記述，その記述（自己の読み）を学習者自身が評価するといった活動を取り入れた。学習者の記述の分析からは，意識的な内省に至らなかった学習者も見受けられたものの，約６割の学習者の記述には変容が見られ，用いた手立ては効果があったと推測できることを指摘した。 en-copyright= kn-copyright= en-aut-name=SAISHOYumi en-aut-sei=SAISHO en-aut-mei=Yumi kn-aut-name=最相有未 kn-aut-sei=最相 kn-aut-mei=有未 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=反省性 (reflectiveness) kn-keyword=反省性 (reflectiveness) en-keyword=情意的性向 (affective disposition) kn-keyword=情意的性向 (affective disposition) en-keyword=複数テクスト (multiple texts) kn-keyword=複数テクスト (multiple texts) en-keyword=「現代の国語」 (“Contemporary Japanese Language”) kn-keyword=「現代の国語」 (“Contemporary Japanese Language”) en-keyword=生物多様性 (biodiversity) kn-keyword=生物多様性 (biodiversity) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preschool Teachers’ Strategies and Practical Challenges in Supporting the School Enrollment of Foreign Children kn-title=外国人幼児の就学支援における保育士の工夫と実践的課題 en-subtitle= kn-subtitle= en-abstract=This study aimed to clarify the specific practices and challenges faced by preschool teachers in supporting foreign children at the time of school enrollment. Semi-structured interviews were conducted with two preschool teachers who had experience in supporting foreign children, and qualitative analysis using SCAT was applied to organize the support provided to both children and their parents. The results revealed that, in terms of language support, teachers utilized visual aids and simplified Japanese, while in cultural support they sought to balance family culture with the culture of the preschool. Regarding developmental support, the importance of fostering non-cognitive skills and collaborating with medical institutions was highlighted. In parent support, participatory involvement and careful explanations were practiced; however, challenges remained in providing institutional information and establishing collaboration with local governments. Based on these findings, it is necessary to establish a regional collaborative system that can provide institutional support for families with multicultural backgrounds, standardize the provision of information, and build practical mechanisms to connect with Japanese language education resources, so that support does not rely solely on the individual efforts of preschool teachers. kn-abstract=　本研究は，外国人幼児が就学期に直面する困難に対応するため，保育士が行っている具体的な保育実践における支援の工夫と課題を明らかにすることを目的とした。外国人幼児の支援経験を有する保育士2 名に半構造化インタビューを行い，SCAT を用いた質的分析により，幼児および保護者への支援内容を整理した。その結果，言語面では視覚的支援ややさしい日本語を活用し，文化面では家庭文化と日本の園文化の調整が行われていた。発達支援においては，非認知的スキルの育成や医療機関との連携の必要性が指摘された。保護者支援では，参加型の関わりや丁寧な説明が実践されていたが，制度情報の提供や行政との連携には課題が残された。これらの結果を踏まえ，今後は保育士の個別的努力に依存しないためにも，多文化背景をもつ家庭への支援を制度的に支える地域連携体制の整備や，情報提供の標準化，日本語教育資源との接続を図る実践的仕組みの構築が求められる。 en-copyright= kn-copyright= en-aut-name=CHENYiwen en-aut-sei=CHEN en-aut-mei=Yiwen kn-aut-name=陳依文 kn-aut-sei=陳 kn-aut-mei=依文 aut-affil-num=1 ORCID= en-aut-name=YANAGISAWAKazuki en-aut-sei=YANAGISAWA en-aut-mei=Kazuki kn-aut-name=柳澤佳月 kn-aut-sei=柳澤 kn-aut-mei=佳月 aut-affil-num=2 ORCID= en-aut-name=REN Xinyu en-aut-sei=REN en-aut-mei= Xinyu kn-aut-name=任芯于 kn-aut-sei=任 kn-aut-mei=芯于 aut-affil-num=3 ORCID= en-aut-name=YOSHITOSHIMunehisa en-aut-sei=YOSHITOSHI en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=4 ORCID= affil-num=1 en-affil=The Joint Graduate School (Ph.D. Program) in Science of School Education, Hyogo University of Teacher, Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院連合学校教育学研究科博士課程 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=外国人幼児 (foreign preschool children) kn-keyword=外国人幼児 (foreign preschool children) en-keyword=就学 (school enrollment) kn-keyword=就学 (school enrollment) en-keyword=保育士 (preschool teachers) kn-keyword=保育士 (preschool teachers) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathological and transcriptomic profiles of 101 patients with diffuse large B-cell lymphoma/high-grade B-cell lymphoma with double-hit MYC and BCL2 or BCL6 and triple hit en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: Diffuse large B-cell lymphoma/high-grade B-cell lymphoma (DLBCL/HGBCL) with MYC and BCL2 rearrangements (double-hit lymphoma with BCL2, DHL-BCL2) is a mature aggressive B-cell lymphoma that also includes concurrent triple hit with BCL6 translocation (TH). DHL with MYC and BCL6 (DH-BCL6) can also occur. The differences among these three DLBCL/HGBCL subtypes have not yet been definitively determined.
Methods and Results: This study characterized the clinicopathological features and transcriptomic profiles of a series of 101 cases of DLBCL/HGBCL that were subclassified according to MYC, BCL2 and BCL6 FISH data, including cell-of-origin (COO)-like, molecular high-grade (MHG)-like and double-hit/dark-zone (DHIT/DZsig)-like signatures. DLBCL/HGBCL-DH-BCL2 was characterized by higher HGBCL morphology, CD10 positivity, GCB Hans's, GCB COO and MHG molecular subtype. DLBCL/HGBCL-TH had higher LDH levels and worse overall survival. DLBCL/HGBCL-DH-BCL6 had higher MUM1 expression, non-GCB Hans', ABC/Unclassified COO, non-MHG and low DHIT/DZ signatures. Transcriptomic analysis showed that DLBCL/HGBCL-DH-BCL2 and DLBCL/HGBCL-TH were close but separated from DLBCL/HGBCL-DH-BCL6. Gene set enrichment analysis (GSEA) revealed different levels of enrichment between the subtypes.
Conclusions: DLBCL/HGBCL-DH-BCL6 differs from the DLBCL/HGBCL-DH-BCL2, and the DLBCL/HGBCL-TH is associated with the worst survival. Analysis of all three genes of MYC, BCL2 and BCL6 is recommended in the context of DLBCL/HGBCL diagnosis. en-copyright= kn-copyright= en-aut-name=MiyaokaMasashi en-aut-sei=Miyaoka en-aut-mei=Masashi

plus lenvatinib focusing on safety outcomes in metastatic renal cell carcinoma: results from the JK-FOOT consortium en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Immune checkpoint inhibitor (ICI)-based combination therapy is a standard first-line treatment for metastatic renal cell carcinoma (mRCC), with combinations such as nivolumab plus cabozantinib (Nivo?+?Cabo) and pembrolizumab plus lenvatinib (Pem?+?Len) demonstrating favorable oncologic outcomes. However, no direct comparisons between these two regimens have been conducted. This study aimed to compare the safety and oncologic outcomes of Nivo?+?Cabo and Pem?+?Len in patients with mRCC.
Methods This retrospective study included 185 patients with mRCC treated with Nivo?+?Cabo (n?=?81) or Pem?+?Len (n?=?104) between January 2018 and June 2025 across multiple institutions. The primary outcome was a comparison of treatment-related adverse events (TrAEs). Oncologic outcomes, including objective response rate (ORR), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS), were compared using one-to-one propensity score matching.
Results Any-grade TrAEs occurred in 90% of patients in the Nivo?+?Cabo group and 92% in the Pem?+?Len group (p?=?0.6). Severe TrAEs (grade???3) were more frequent in the Pem?+?Len group (44%) than in the Nivo?+?Cabo group (30%, p?=?0.048). Tyrosine kinase inhibitor dose reduction and treatment discontinuation rates were similar between groups. In the matched cohort (Nivo?+?Cabo: n?=?74; Pem?+?Len: n?=?74), ORRs were comparable (66% vs. 71%, p?=?0.6). With a median follow-up of 17 months, no significant differences were observed in PFS (p?=?0.4), CSS (p?=?0.9), or OS (p?=?0.5).
Conclusions Nivo?+?Cabo and Pem?+?Len demonstrated similar oncologic efficacy as first-line treatments for mRCC. However, Pem?+?Len was associated with more severe TrAEs. Careful toxicity management and shared decision-making are essential when selecting ICI-based combinations. en-copyright= kn-copyright= en-aut-name=YanagisawaTakafumi en-aut-sei=Yanagisawa

kn-subtitle= en-abstract= kn-abstract=The sintering conditions using hot isostatic press (HIP) of yttria-stabilized zirconia (YSZ) were investigated to obtain a dense YSZ layer at low sintering temperature such as 1000°C for an electrolyte of metal-supported solid oxide fuel cell. It was found that a dense YSZ pellet with relative density of 93% could be obtained under a sintering condition of 1000°C-10 hours with HIP in 195 MPa. On the other hand, in X-ray diffraction analysis of the dense YSZ pellet, peaks of the monoclinic phase were slightly detected in addition to peaks of the cubic phase. From energy dispersive X-ray spectroscopy analysis, a small amount of boron was detected in the dense YSZ pellet. It is considered that the YSZ crystalline phase transformation of cubic to monoclinic phase was occurred by the boron diffusion from the diffusion barrier coating of metal foil capsule used for the HIP. en-copyright= kn-copyright= en-aut-name=MANABEKyohei en-aut-sei=MANABE en-aut-mei=Kyohei kn-aut-name=真鍋享平 kn-aut-sei=真鍋 kn-aut-mei=享平 aut-affil-num=1 ORCID= en-aut-name=ECHIGOMitsuaki en-aut-sei=ECHIGO en-aut-mei=Mitsuaki kn-aut-name=越後満秋 kn-aut-sei=越後 kn-aut-mei=満秋 aut-affil-num=2 ORCID= en-aut-name=KISHIMOTOAkira en-aut-sei=KISHIMOTO en-aut-mei=Akira kn-aut-name=岸本昭 kn-aut-sei=岸本 kn-aut-mei=昭 aut-affil-num=3 ORCID= affil-num=1 en-affil=Osaka Gas Co.

In addition to primary symptoms, including oral and genital ulcers, ocular involvement, and skin lesions, BD can also affect various organs. However, renal involvement, particularly in tubulointerstitial nephritis, has rarely been described. Herein, a rare case of acute tubulointerstitial nephritis in a patient clinically diagnosed with BD is reported. The renal lesion presented with other symptoms of BD and fever, and was considered to be BD-related due to the presence of neutrophilic infiltration and its responsiveness to BD-directed therapy. Alterations in T-helper (Th) 1, Th2, and Th17 cytokine profiles are associated with BD activity. Interleukin (IL)-17 plays a central role in neutrophil activation, and recent studies have demonstrated a strong correlation between IL-17A levels and BD activity. In the present case, elevated serum IL-17A levels and infiltration of IL-17A-positive cells into the renal tissue reflected an active phase of BD and a BD-associated renal lesion. en-copyright= kn-copyright= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KubotaNatsuki en-aut-sei=Kubota en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, 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= en-keyword=Tubulointerstitial nephritis kn-keyword=Tubulointerstitial nephritis en-keyword=Beh?et’s disease kn-keyword=Beh?et’s disease en-keyword=Neutrophils kn-keyword=Neutrophils en-keyword=Interleukin-17 kn-keyword=Interleukin-17 en-keyword=T-helper (Th) 1/Th2/Th17 cytokines kn-keyword=T-helper (Th) 1/Th2/Th17 cytokines END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=3 article-no= start-page=580 end-page=589 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Cysteine-Specific Cationization Strategy for Versatile Antibody Production against Intrinsically Disordered Proteins en-subtitle= kn-subtitle= en-abstract= kn-abstract=Several autoantigens relevant to the immune system, especially those targeted by autoantibodies induced by antitumor responses, tend to be rich in disordered regions and are prone to aggregation. This inherent instability presents significant challenges for the production, purification, and analysis of autoantigens in laboratory settings. Cysteine-specific cationization can effectively solubilize and purify these challenging proteins, allowing the isolation of full-length water-soluble antigens in their denatured state. The purified antigens enable accurate multiplex autoantibody assays using a suspension Luminex bead array platform. However, well-validated positive control antibodies are essential to ensuring precise clinical diagnosis. In this study, we prepared and characterized a panel of control antibodies by immunizing rabbits with cysteine-specific S-cationized antigens. The resulting antibodies predominantly recognized linear epitopes and were highly effective as quality control reagents in autoantibody array assays. Additionally, these antibodies maintained their ability to bind to their native, unmodified intracellular counterparts, highlighting the usefulness of this approach for producing antibodies against intrinsically disordered proteins. Although a modest immune response against the S-cationized modification site was observed, it remained minimal and did not affect the usefulness of the antibodies for assay validation. We propose this versatile cysteine-specific cationization platform for managing unstable proteins rich in disordered regions, supporting antigen production for diagnostics, and antibody development for research and validation purposes. en-copyright= kn-copyright= en-aut-name=SakaguchiRyui en-aut-sei=Sakaguchi en-aut-mei=Ryui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoAi en-aut-sei=Miyamoto en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KutsumaRikako en-aut-sei=Kutsuma en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriTakeru en-aut-sei=Mori en-aut-mei=Takeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakashimaDaichi en-aut-sei=Nakashima en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasuiMirei en-aut-sei=Masui en-aut-mei=Mirei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HonjoTomoko en-aut-sei=Honjo en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FutamiMidori en-aut-sei=Futami en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriiMariko en-aut-sei=Morii en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FutamiJunichiro en-aut-sei=Futami en-aut-mei=Junichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Bioscience, Faculty of Life Science, Okayama University of Science kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=10 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=3 article-no= start-page=e202500639 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PPy‐Coated Wire Actuators for the Micromechanostimulation of Cells: Fabrication and Characterization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular mechanotransduction signals play a crucial role in physiological and pathological conditions, including skeletal disorders. Although various systems exist to mechanically stimulate cultured cells, most are constrained by incubator incompatibility, limited physiological relevance, nonuniform stimulation, or complexity. The objective of this article is to develop and validate a compact, incubator-compatible tool capable of delivering localized and physiologically relevant mechanical stimulation to small cell populations. Here, we introduce a polypyrrole-based wire-shaped microactuator designed to induce localized mechanical stress to adjacent cells. These wire-shaped microactuators are biocompatible, easy-to-use, and compact for use within standard in vitro cell culture systems. Using a noncontact optical method, we characterize the actuation of polypyrrole-coated wires in an aqueous NaDBS electrolyte, showing radial expansion of 1.5?8??m depending on the deposited polypyrrole film thickness, comparable to cellular dimensions. Next, the actuation is confirmed to be robust and stable to use in cell culture media at physiological temperature. To evaluate biological relevance, osteoblastic KUSA-A1 cells are mechanically stimulated inside the incubator and transcriptomic changes are assessed. Mechanical stimulation resulted in upregulation of genes previously associated with mechanotransduction, including Fos and Fosb. Additionally, several uncharacterized long noncoding RNAs are differentially expressed, suggesting potential novel players in the mechanotransduction pathway. en-copyright= kn-copyright= en-aut-name=Ortega‐SantosAmaia B. en-aut-sei=Ortega‐Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Mart?nezJose G. en-aut-sei=Mart?nez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JagerEdwin W.

WGCNA enables the identification of gene clusters (modules) exhibiting correlated expression patterns, the association of these modules with traits, and the exploration of candidate biomarker genes by focusing on hub genes within the modules. WGCNA has been successfully applied in diverse biological contexts. However, conventional algorithms manifest three principal limitations: the assumption of scale-free topology, the requirement for parameter tuning, and the neglect of regression line slopes. These limitations are addressed by SGCRNA. SGCRNA provides Julia functions for the analysis of co-expression networks derived from various types of biological data, such as gene expression data.

In our previous work, we constructed a non-interactive proactive secret scheme by integrating threshold homomorphic encryption (ThHE) while reducing the communication complexity to ?(?). Not only is refreshing shares important but revoking the shares of users who have left the system is also essential in practical dynamic membership scenarios. However, the previous work was insufficient for supporting explicit user revocation. This study strengthens the description of roles for authorized users and proposes a scheme to achieve non-interactive share refresh and dynamic user management. In each epoch, authorized users are classified into three roles: retain, newly join, and rejoin, and they receive a broadcast of the compact ciphertext encoding both the refresh information and the revocation instructions from the trusted center (dealer). Authorized users independently derive new shares through homomorphic computations, whereas revoked users are unable to generate new shares. Hash functions are used to bind revocation parameters to the cryptographic hashes of valid users in order to guarantee integrity during revocation, allowing for effective verification without compromising non-interactivity. Our new scheme not only extends the revocation structure but also preserves the ?(?) communication complexity. en-copyright= kn-copyright= en-aut-name=HeYixuan en-aut-sei=He en-aut-mei=Yixuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Interdisciplinary Education and Research Field, Okayama University kn-affil= en-keyword=proactive secret sharing kn-keyword=proactive secret sharing en-keyword=user revocation kn-keyword=user revocation en-keyword=threshold homomorphic encryption kn-keyword=threshold homomorphic encryption en-keyword=non-interactive kn-keyword=non-interactive END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=21 article-no= start-page=6651 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Integrated Authentication Server Design for Efficient Kerberos?Blockchain VANET Authentication en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vehicular Ad Hoc Network (VANET) is a fundamental component of the intelligent transportation systems (ITS), providing critical road information to users. However, the volatility of VANETs creates significant vulnerabilities from malicious actors. Thus, verifying joining entities is crucial to maintaining the VANET’s communication security. Authentication delays must stay below 100 ms to meet VANET requirements, posing a major challenge for security. Our previous research introduced a Kerberos?Blockchain (KBC) authentication system that contains two main components separately: Authentication Server (AS) and Ticket Granting Server (TGS). However, this KBC architecture required an additional server to accommodate increasing vehicle volumes in urban environments, leading to higher infrastructure costs. This paper presents an integrated authentication server that merges AS and TGS into a Combined Server (CBS) while retaining blockchain security. We evaluate it using OMNeT++ with SUMO for traffic simulation and Ganache for blockchain implementation. Results show that CBS removes the need for an extra server while keeping authentication delays under 100 ms. It also improves throughput by 104% and reduces signaling overhead by 45% compared to KBC. By optimizing authentication without compromising security, the integrated server greatly enhances the cost-effectiveness and efficiency of VANET systems. en-copyright= kn-copyright= en-aut-name=RahayuMaya en-aut-sei=Rahayu en-aut-mei=Maya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HossainMd.

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

SDM is a recommended approach to clinical decision-making that emphasizes mutual information sharing and deliberation between physicians and patients. Traditional models often assume that patients can clearly articulate their values, preferences, and treatment goals. However, in actual clinical settings, particularly in cases of serious illness or life-threatening situations, patients frequently face emotional distress and psychological burdens, which can hinder their active participation in decision-making and the expression of their preferences. Based on SDM theory and practice reports, this study argues that SDM should not be viewed merely as a process that promotes patient choice. Even when patients choose not to actively participate and ultimately delegate decisions to healthcare providers or family members, such a choice can represent autonomous decision-making if it arises through meaningful communication and mutual understanding. This perspective calls for a more comprehensive and flexible interpretation of patient participation in SDM practice. en-copyright= kn-copyright= en-aut-name=YOSHIDAMiho en-aut-sei=YOSHIDA en-aut-mei=Miho kn-aut-name=吉田美穂 kn-aut-sei=吉田 kn-aut-mei=美穂 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems Okayama University kn-affil=国立大学法人岡山大学学術研究院ヘルスシステム統合科学研究学域 en-keyword=Shared Decision-Making kn-keyword=Shared Decision-Making en-keyword=Patient Participation kn-keyword=Patient Participation en-keyword=Physician?Patient Relationship kn-keyword=Physician?Patient Relationship END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=7 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Preliminary Study on Nursing Care Technology: A Case Study of Elderly Care kn-title=介護技術論試論―高齢者介護を事例として― en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the first part of this paper, it was confirmed that the term “kaigo” (nursing care) was coined and its meaning defined during discussions on enacting social welfare legislation accompanying societal aging, as the care aspect was being “differentiated” from the “family’s health and welfare functions.” The paper also examined how the term “kaigo gijutsu”(nursing care technique) has been defined and used. In the latter part, based on the author’s own definition of “kaigo gijutsu”(nursing care technology), an attempt was made to analyze examples of technology utilization in nursing care settings, focusing on papers published in specialized welfare and nursing care technology journals. Through this preliminary study, it was shown that the author’s definition of “nursing care technology” clearly distinguishes between the means for care activities?such as welfare equipment?and the care recipients and caregivers who make use of them, and that this definition is useful for grasping the essence of challenges in nursing care settings. en-copyright= kn-copyright= en-aut-name=YOSHIBAYasuyuki en-aut-sei=YOSHIBA en-aut-mei=Yasuyuki kn-aut-name=吉葉恭行 kn-aut-sei=吉葉 kn-aut-mei=恭行 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil=岡山大学学術研究院ヘルスシステム統合科学学域 en-keyword=Nursing Care Technology kn-keyword=Nursing Care Technology en-keyword=Elderly Care kn-keyword=Elderly Care en-keyword=welfare equipment kn-keyword=welfare equipment END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The effects of cold compresses on itching in patients with atopic dermatitis: A cross-over controlled pilot trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=This cross-over controlled trial aimed to evaluate the effectiveness and safety of two types of cold compresses (towels and ice packs) in alleviating itching among patients with atopic dermatitis. The study recruited 19 participants diagnosed with atopic dermatitis and suffering from chronic itching for over 6 months. Each participant received both types of cold compress interventions. Itching sensations were assessed repeatedly using a visual analogue scale before and after the application of the cold compress. The mean and standard deviation of itching scores for the towel intervention were 16.9 ± 19.1 (baseline) and 11.4 ± 16.1 (post-application). For the ice pack intervention, the scores were 13.6 ± 14.7 (baseline) and 6.2 ± 9.8 (post-application). Although there was a reduction in mean itching scores following the application of cold compresses, the differences were not statistically significant for either intervention. Despite the lack of statistical significance, this study suggests that cold compresses, which are user-friendly and inexpensive, may safely reduce subjective itching in patients with atopic dermatitis without causing pain or discomfort. However, further research with a larger sample size is needed to confirm these findings. en-copyright= kn-copyright= en-aut-name=HIRAMIYuki en-aut-sei=HIRAMI en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HARADANahoko en-aut-sei=HARADA en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ONOMiho en-aut-sei=ONO en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KODAMasahide en-aut-sei=KODA en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FUKAIKiyoko en-aut-sei=FUKAI en-aut-mei=Kiyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Former Department of Nursing, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nursing Science, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Nursing, Faculty of Health, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=4 en-affil=Co-learning Community Healthcare Re-innovation Office, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Professor Emeritus, Okayama University, Graduate School of Nursing, The Jikei University School of Medicine kn-affil= en-keyword=Atopic Dermatitis kn-keyword=Atopic Dermatitis en-keyword=Pruritus kn-keyword=Pruritus en-keyword=Cryotherapy kn-keyword=Cryotherapy en-keyword=Quality of Life kn-keyword=Quality of Life en-keyword=Skin Temperature kn-keyword=Skin Temperature END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=2025 cd-vols= no-issue= article-no= start-page=9884345 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparing the Activity of Peripheral Blood Mononuclear Cells Frozen Under Electromagnetic Field Freezing and Standard Slow-Freezing en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peripheral blood mononuclear cells (PBMCs) are cells obtained from the blood that are used not only in clinical tests but also in various research applications. The slow-freezing (SLF) method, currently the standard for PBMC cryopreservation, involves extended storage at ?80°C before transfer to liquid nitrogen. Delays in this transfer, such as overnight or weekend holds, risk a gradual decline in cell viability. Additionally, variability in freezing duration can lead to inconsistent cell quality, emphasizing the need for an alternative freezing method that allows for more timely transfer to liquid nitrogen. This study is aimed at clarifying whether the method of using a freezer with an applied electromagnetic field (EMF) is superior to the currently used standard SLF method for PBMC cryopreservation. A comparison of the number of viable cells, cell viability, and cell activity showed that the EMF method was equivalent to the SLF method. However, the shortest time required for freezing was significantly shorter with the EMF method than the SLF method (0.25 vs. 3?h), allowing for earlier transfer of PBMC to liquid nitrogen. This demonstrates that the EMF method offers an advantage in operational efficiency, particularly for facilities that routinely process and store PBMCs, such as biobanks and other storage-focused departments. en-copyright= kn-copyright= en-aut-name=MatsubaraTakehiro en-aut-sei=Matsubara en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiMina en-aut-sei=Takagi en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UwaboTakahiro en-aut-sei=Uwabo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SohJunichi en-aut-sei=Soh en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Okayama University Hospital Biobank kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Biorepository Research and Networking, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Osaka Metropolitan University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Okayama University Hospital Biobank kn-affil= affil-num=6 en-affil=Okayama University Hospital Biobank kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=8840 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tribolium castaneum with longer duration of tonic immobility have more variations corresponding to the human Parkinson’s disease genomic region en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson’s disease (PD) is a common neurodegenerative syndrome characterized by the loss of dopaminergic neurons and is also a progressive neurodegenerative disorder that is characterized by dopamine deficiency. We established strains artificially selected for longer and shorter durations of tonic immobility, an antipredator behavior that has received much attention recently, in the red flour beetle, Tribolium castaneum, a model insect species for molecular analyses different from Drosophila melanogaster. Previous studies have shown that the long strains (L-strain) have significantly lower levels of dopamine expression in the brain than the short strains (S-strain) and that they have an abnormal pattern of locomotor activity. Furthermore, previous studies have shown that administering dopamine to L-strain beetles reduces the duration of tonic immobility. Transcriptome analysis of brain and thorax of the L- and S-strains also showed differences in mRNA expression of genes involved in dopamine synthesis and tyrosine metabolism. These results indicate that the phenotype and molecular basis of the L-strain are similar to those of Parkinson’s syndrome symptoms. In order to establish a link between T. castaneum and PD, we compared the DNA sequences of the L- and S-strains to human genes affecting dopaminergic pathways. The DNA comparison revealed many mutated regions in these genes in the L-strain. We discuss the relationship between dopaminergic pathway genes and PD-like phenotypes across humans, Drosophila, and the red flour beetle. en-copyright= kn-copyright= en-aut-name=TanakaKeisuke en-aut-sei=Tanaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiKen en-aut-sei=Sasaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YajimaShunsuke en-aut-sei=Yajima en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Tamagawa University kn-affil= affil-num=3 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=42 end-page=50 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=Biosensing method of growth diagnosis in the forced culture of strawberries ―Development of crop-identification algorithms― en-subtitle= kn-subtitle= en-abstract= kn-abstract=An image-processing algorithm for identifying individual crops is developed for labor-savings and time-series biological information collection. Information including the leaf development frequency are diagnostic indicators of strawberry growth. The algorithm is designed for drones in greenhouses that cannot acquire location information using the global navigation satellite system (GNSS). Drones fly over crop rows and sequentially assign identification numbers (IDs) to crops. Object-detection artificial intelligence (AI) is used to estimate the crop zone, and the ID is based on the crops number difference between frames. The previous misdetection rate was 1.06 %, failing to identify crops, which decreases to 0.31 % using the proposed algorithm. Furthermore, because there are no failures in consecutive frames, IDs are assigned to all crops correctly. en-copyright= kn-copyright= en-aut-name=TSUBOTAShogo en-aut-sei=TSUBOTA en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NAMBAKazuhiko en-aut-sei=NAMBA en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KASEIShota en-aut-sei=KASEI en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FUKATSUTokihiro en-aut-sei=FUKATSU en-aut-mei=Tokihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= affil-num=4 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= en-keyword=strawberry kn-keyword=strawberry en-keyword=forcing culture kn-keyword=forcing culture en-keyword=image-processing kn-keyword=image-processing en-keyword=object-detection kn-keyword=object-detection en-keyword=identification of individual crops kn-keyword=identification of individual crops en-keyword=drones kn-keyword=drones END start-ver=1.4 cd-journal=joma no-vol=119 cd-vols= no-issue=1 article-no= start-page=9 end-page=17 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=Big data-driven target identification by machine learning: DRD2 as a therapeutic target for psoriasis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The development of medical treatments has traditionally relied on researchers leveraging scientific knowledge to hypothesize disease mechanisms and identify therapeutic agents. However, the depletion of novel therapeutic targets has become a significant challenge, resulting in stagnation within pharmaceutical research.
Objective: To address the scarcity of therapeutic targets, we developed a machine learning (ML)-based system capable of predicting therapeutic target molecules for diseases. To validate its utility, we applied this system to psoriasis, aiming to identify novel treatment strategies.
Methods: Our approach utilized a large clinical database to calculate reporting odds ratios for all drugs associated with the prevention of diseases of interest. We identified target proteins by analyzing large chemical structure databases to discover proteins commonly associated with preventive drug candidates. Experimental validation was conducted by administering a predicted therapeutic candidate in an imiquimod-induced psoriasis mouse model.
Results: The ML-based predictions identified drugs for Parkinson’s disease as potential preventive candidates for psoriasis. Further analysis highlighted dopamine receptor D2 (DRD2) as a therapeutic target. Administration of a DRD2 agonist alleviated psoriasis symptoms in mice, evidenced by the downregulation of mRNA expression in the IL-17 pathway and reduced serum tumor necrosis factor-α levels.
Conclusion: This study demonstrates the utility of a novel ML-based system for identifying therapeutic targets, as shown by its successful application in uncovering the role of DRD2 in psoriasis. Beyond psoriasis, this system offers significant potential for exploring pathological mechanisms and discovering therapeutic targets across various diseases. en-copyright= kn-copyright= en-aut-name=SakaiTakashi en-aut-sei=Sakai en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IchinoseOtoha en-aut-sei=Ichinose en-aut-mei=Otoha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TerabayashiTakeshi en-aut-sei=Terabayashi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HatanoYutaka en-aut-sei=Hatano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamanishiYoshihiro en-aut-sei=Yamanishi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshizakiToshimasa en-aut-sei=Ishizaki en-aut-mei=Toshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Dermatology, Faculty of Medicine, Oita University kn-affil= affil-num=2 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Bioscience and Bioinformatics, Faculty of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=4 en-affil=Department of Pharmacology, Faculty of Medicine, Oita University kn-affil= affil-num=5 en-affil=Department of Dermatology, Faculty of Medicine, Oita University kn-affil= affil-num=6 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=7 en-affil=Department of Pharmacology, Faculty of Medicine, Oita University kn-affil= en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=big data kn-keyword=big data en-keyword=machine learning kn-keyword=machine learning en-keyword=dopamine receptor D2 kn-keyword=dopamine receptor D2 en-keyword=psoriasis kn-keyword=psoriasis END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=JFST0004 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Numerical analysis validating the standard k-epsilon model for the kinetic energy of turbulence subjected to weak but long-lasting wind tunnel blockage acceleration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the effect of weak but prolonged mean flow accelerations, such as those observed in wind tunnel blockage acceleration, on free-stream turbulence. Specifically, this research aims to validate a model previously developed based on the k-epsilon model. To test this model, the study focuses on scenarios where the turbulence under acceleration is steady and isotropic, since the model suggests that this type of acceleration has no effect on the turbulent kinetic energy. To examine this suggestion, the turbulence within a periodic box was analyzed using large-eddy simulation (LES) based on the conventional Smagorinsky model framework. The numerical analysis is based on a method that conserves velocity fluctuation intensities. The results show that while high rate of acceleration deviates turbulent kinetic energy, low rate acceleration has hardly any effect on turbulent kinetic energy, enstrophy, pressure fluctuation, relative pressure fluctuation intensity, and higher-order statistics of a velocity fluctuation. These results validate the accuracy of the model proposed in the previous studies. These results were obtained by focusing on differences in Reynolds numbers and the spatial scale of the forcing. en-copyright= kn-copyright= en-aut-name=ONOAkira en-aut-sei=ONO en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Homogeneous turbulence kn-keyword=Homogeneous turbulence en-keyword=K-epsilon model kn-keyword=K-epsilon model en-keyword=Wind tunnel blockage kn-keyword=Wind tunnel blockage END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=110 end-page=118 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=Trend of adjusted antenatal care visits on pregnant women and neonatal during the COVID-19 pandemic: Findings from a three districts survey in 2021 en-subtitle= kn-subtitle= en-abstract=Upaya pengembangan kesehatan berkelanjutan di tengah wabah penyakit menular seperti COVID-19 memerlukan sistem kesehatan ibu yang tangguh.

With cases rising globally and across Asia, Indonesia faces significant disruptions in essential services. A critical research gap exist in utilizing adjusted time-series analysis to isolated pandemic impact from seasonal variation in urban Indonesia. This study evaluates trends in antenatal care (ANC) visits (January 2019?December 2020) at three Community Health Centres in Makassar: Bara-Baraya, Jongaya and Batua using Interrupted Time Series (ITS) analysis. Findings reveal a significant decline in visits during the second and third quarters of 2020, primarily due to transmission fears. We suggest integration of telemedicine and home visits to maintain continuity of care. Although focused on urban Makassar, these results are an important reference for health and offer applicable solutions for other developing countries facing resource constraints. This study emphasizes the need for inclusive prevention strategies to protect maternal health in urban and rural areas in low- to middle-income countries during systemic health crises. en-copyright= kn-copyright= en-aut-name=IbrahimJuliani en-aut-sei=Ibrahim en-aut-mei=Juliani 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=IbrahimSukaeni en-aut-sei=Ibrahim en-aut-mei=Sukaeni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Departement of Public Health, Faculty of Medicine and Health Science, Universitas Muhammadiyah Makassar kn-affil= affil-num=2 en-affil=Nursing of Department, Graduate School of Health Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Bosowa University kn-affil= en-keyword=antenatal care kn-keyword=antenatal care en-keyword=covid-19 kn-keyword=covid-19 en-keyword=interrupted time series kn-keyword=interrupted time series en-keyword=maternal health kn-keyword=maternal health en-keyword=neonatal birth kn-keyword=neonatal birth END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=9 article-no= start-page=14570 end-page=14577 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Water-Resistant Antibacterial Coatings Using Cetylpyridinium Chloride - Graphene Oxide Composites en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hospital-acquired infections remain a persistent threat in healthcare settings, especially with the increasing number of elderly and immunocompromised patients. In situations where the use of disposable materials is difficult, durable antibacterial surface coatings are essential. In this study, we report the structural characterization of cetylpyridinium chloride-graphene oxide (CPC?GO) hybrid materials and the sustainability of their antibacterial effects, aiming at washable antibacterial coatings for medical applications. Graphene oxide (GO) has a large surface area and numerous functional groups, while cetylpyridinium chloride (CPC) is a quaternary ammonium compound with well-documented antibacterial activity. We hypothesized that the stable incorporation of CPC through the functional groups of GO could improve surface retention and provide long-term antibacterial performance. The structural properties of the CPC?GO composites were characterized by UV?vis spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and atomic force microscopy. These analyses confirmed the formation of a complex through ionic bonds and the maintenance of a planar composite structure. The antibacterial performance of the CPC?GO coatings was examined using representative bacteria. Notably, the CPC?GO coatings maintained their antibacterial activity significantly better than the negative controls even after multiple washings. The excellent surface retention of the CPC?GO composite suggests its potential as a next-generation antibacterial coating for areas where disinfection and sterilization are impossible, such as the interior of complex medical devices. This study suggests a strategy to extend the efficacy of existing antibacterial agents through the application of nanomaterials. Future studies will focus on the controlled release, long-term stability, and biocompatibility of CPC to realize clinical applications. 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=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, 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= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=6 article-no= start-page=845 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Seasonal Variations in the Risk of Outpatient Acute Kidney Injury in Patients with Chronic Kidney Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Acute kidney injury (AKI) frequently occurs in the outpatient setting and is associated with adverse renal and survival outcomes. However, there is no established definition of outpatient AKI, and the risk factors, especially seasonal variation, remain limited. This study aimed to investigate seasonal variation in the risk of outpatient AKI. Methods: This retrospective observational study used routinely collected clinical laboratory data from a single hospital in Japan between 2007 and 2022. Outpatient AKI was defined as ?35% relative decline in estimated glomerular filtration rate (eGFR) compared with a preceding outpatient measurement obtained within 14?90 days. Monthly and seasonal variations in outpatient AKI risk in patients with chronic kidney disease (CKD) were evaluated using logistic regression models. Subgroup analyses were performed according to AKI stage, age group, and CKD stage. Results: A total of 203,853 outpatient records were analyzed. The incidence of outpatient AKI was highest in August and lowest in November. Analyses demonstrated significantly increased odds ratios of outpatient AKI in January, February, July, and August. Seasonally, the risk was significantly higher during the summer. Stage-specific analyses showed that AKI stage 1 was more frequent in the summer, whereas AKI stage 2 tended to increase during the winter. Conclusions: Outpatient AKI exhibits distinct seasonal patterns, with increased risk during both summer and winter and differential associations according to AKI severity and baseline kidney function. Recognition of these patterns may help identify vulnerable populations and inform targeted preventive strategies for outpatient AKI. en-copyright= kn-copyright= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki 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=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HaraguchiSoichiro en-aut-sei=Haraguchi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=acute kidney injury kn-keyword=acute kidney injury en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=outpatients kn-keyword=outpatients en-keyword=seasons kn-keyword=seasons END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=6 article-no= start-page=657 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adolescent screen use in the pre-internet era and subsequent health and well-being: an outcome-wide longitudinal study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study used data from the National Longitudinal Study of Adolescent to Adult Health (Add Health, N?=?11,054) to assess whether increases in screen-based leisure during adolescence (Wave II, from 1996) predicted adult well-being (Wave IV, from 2008-09), adjusting for a wide range of covariates (Wave I, from 1995). Using an outcome-wide analytic approach, we examined associations between screen time and 38 adult outcomes, adjusting for prior screen time, values of most outcomes, and confounders. Most associations were null. Modest evidence was found for links between screen time (continuous) and reduced sense of control, illicit drug use, and allostatic load. High screen time (14 h/week) or more also showed weak associations with lower depression and preventive care use. Because the data predate widespread internet use, the findings help establish a baseline for the long-term effects of non-internet screen activities, which appeared to behave had limited impact on adult health and well-being. en-copyright= kn-copyright= en-aut-name=de la Rosa Fern?ndez-PachecoPedro Antonio en-aut-sei=de la Rosa Fern?ndez-Pacheco en-aut-mei=Pedro Antonio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WilkinsonRenae en-aut-sei=Wilkinson en-aut-mei=Renae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CowdenRichard G. en-aut-sei=Cowden en-aut-mei=Richard G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChenYing en-aut-sei=Chen en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CaseBrendan en-aut-sei=Case en-aut-mei=Brendan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=VanderWeeleTyler J. en-aut-sei=VanderWeele en-aut-mei=Tyler J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Youth in Transition, Institute for Culture and Society, Universidad de Navarra kn-affil= affil-num=2 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=3 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=4 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=5 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Leisure kn-keyword=Leisure en-keyword=Television kn-keyword=Television en-keyword=Outcome-wide epidemiology kn-keyword=Outcome-wide epidemiology en-keyword=Video games kn-keyword=Video games en-keyword=Adolescence kn-keyword=Adolescence en-keyword=Well-being kn-keyword=Well-being END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=2 article-no= start-page=dmm052605 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A genetic model of congenital intestinal atresia implicates Mypt1 in epithelial organisation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Congenital intestinal atresia (IA) is a birth defect characterised by the absence or closure of part of the intestine. Although genetic factors are implicated, mechanistic understanding has been hindered by the lack of suitable animal models. Here, we describe a medaka (Oryzias latipes) mutant, generated by N-ethyl-N-nitrosourea (ENU) mutagenesis, that develops IA during embryogenesis. Positional cloning identified a nonsense mutation in mypt1, encoding myosin phosphatase target subunit 1. Mutant embryos exhibited ectopic accumulation of F-actin and phosphorylated myosin regulatory light chain (Mrlc) in the intestinal epithelium, consistent with disrupted actomyosin regulation. These cytoskeletal abnormalities were accompanied by epithelial disorganisation, without notable alterations in cell proliferation, motility or apoptosis. Inhibition of myh11a, encoding smooth muscle (SM) myosin heavy chain, ameliorated the IA phenotype, whereas blebbistatin treatment completely rescued the defect, suggesting a non-contractile role prior to SM maturation. Together, these findings demonstrate that mypt1 loss disrupts intestinal morphogenesis through actomyosin dysregulation. Given the recent clinical identification of IA associated with MYPT1 variants, this medaka model offers a valuable platform to investigate the developmental and molecular basis of MYPT1-associated IA in humans. en-copyright= kn-copyright= en-aut-name=KobayashiDaisuke en-aut-sei=Kobayashi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UrasakiAkihiro

andrastins en-subtitle= kn-subtitle= en-abstract= kn-abstract=We designed and synthesized structurally simple farnesyl transferase (FTase) inhibitors (1a?1d) by leveraging andrastin, a natural product with FTase inhibitory activity. 1a?1d possess a cyclopentane-1,3-dione core, which is critical for FTase recognition; a farnesyl moiety, which is a simplified motif of A to C rings of andrastin; and a carboxylic acid or methoxycarbonyl group, which enables multipoint hydrogen bonding interactions with FTase. Competitive inhibition experiments revealed that 1d has the most potent FTase inhibitory activity. Docking simulation analysis of 1a?1d with FTase suggested that the multipoint hydrogen bonding interactions between the cyclopentane-1,3-dione moiety and the carboxyl group play an important role in FTase recognition. en-copyright= kn-copyright= en-aut-name=KitamuraFumino en-aut-sei=Kitamura en-aut-mei=Fumino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniokaMasaru en-aut-sei=Tanioka en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakaAyano en-aut-sei=Kosaka en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuzawaNao en-aut-sei=Matsuzawa en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObitaTakayuki en-aut-sei=Obita en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakajiriYuko en-aut-sei=Sakajiri en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShibataTomokazu en-aut-sei=Shibata en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YokoyamaTakeshi en-aut-sei=Yokoyama en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KohyamaAki en-aut-sei=Kohyama en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamadaTsuyoshi en-aut-sei=Yamada en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamanishiYoshihiro en-aut-sei=Yamanishi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MizuguchiMineyuki en-aut-sei=Mizuguchi en-aut-mei=Mineyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MatsuyaYuji en-aut-sei=Matsuya en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=2 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=3 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=4 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=5 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=6 en-affil= kn-affil= affil-num=7 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=8 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=10 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=11 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=12 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=13 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=14 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= en-keyword=Andrastin analogs kn-keyword=Andrastin analogs en-keyword=Farnesyl transferase (FTase) inhibitor kn-keyword=Farnesyl transferase (FTase) inhibitor en-keyword=Hydrogen bonding interactions kn-keyword=Hydrogen bonding interactions en-keyword=Cyclopentane-1,3-dione kn-keyword=Cyclopentane-1,3-dione en-keyword=Molecular docking kn-keyword=Molecular docking END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=5 article-no= start-page=1535 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=A Proposal of Secure and Automated Over-the-Air Firmware Update Mechanism for IoT Devices Using Continuous Integration and Continuous Delivery en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Internet of Things (IoT) technology has grown rapidly over the past decade, resulting in deployments of thousands of IoT devices around the world. Then, managing firmware updates for these numerous devices poses significant challenges. Firmware updates face issues such as version rollback, modified firmware files, and potential man-in-the-middle (MITM) attacks, highlighting the need for a secure over-the-air (OTA) firmware update mechanism. In this paper, we propose an automated OTA firmware update mechanism, integrated with continuous integration (CI) and continuous delivery (CD) to ensure trusted sources for firmware origins. It offers security, error handling during firmware updates, and monitoring of the update process. For evaluations, we implemented the proposal with the SEMAR IoT application server that has been implemented in our previous studies. Then, we verified the integrity and authentication, measured the performance and resource utilization, and performed benchmarking tests to assess the efficiency. The results demonstrate that the proposal is sufficiently reliable and efficient. en-copyright= kn-copyright= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= 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=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=3 ORCID= 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=4 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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= en-keyword=Internet of Things (IoT) kn-keyword=Internet of Things (IoT) en-keyword=over-the-air (OTA) firmware update kn-keyword=over-the-air (OTA) firmware update en-keyword=security kn-keyword=security en-keyword=continuous integration (CI) kn-keyword=continuous integration (CI) en-keyword=continuous delivery (CD) kn-keyword=continuous delivery (CD) END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=3 article-no= start-page=e70044 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Simple Method for RNA-Seq of Manually Isolated Chromatophores in Oryzias Fishes en-subtitle= kn-subtitle= en-abstract= kn-abstract=RNA sequencing (RNA-seq) has become an essential tool for analyzing gene expression and exploring cell type?specific transcriptomes. 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.

In this case, the area with 3 days total precipitation of near or more than 300 mm was distributed widely from northern Kyushu to Shiga and Fukui Prefectures. As in the many heavy rainfall events around Kyushu District in the mature stage of the Baiu season, contribution of the intense rainfall with more than 4 mm/10-minute (24 mm/h) attained about one third of the areal mean total precipitation. However, it is noted that the "not so intense rain" with less than 2 mm/10-minute (12 mm/h) also contributed to about one third of the huge total precipitation in the wide area. In short, this case could be characterized by the mixture of the western Japan type heavy rainfall event and the eastern Japan type one. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=MATSUMOTOKengo en-aut-sei=MATSUMOTO en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=2 ORCID= en-aut-name=OTANIKazuo en-aut-sei=OTANI en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域（理科） affil-num=2 en-affil=Okayama Gakugeikan High School kn-affil=岡山学芸館高等学校 affil-num=3 en-affil=TV Setouchi Broadcasting Co., LTD. kn-affil=テレビせとうち(株) en-keyword=western Japan heavy rainfall in July 2018 kn-keyword=western Japan heavy rainfall in July 2018 en-keyword=10-minute precipitation data kn-keyword=10-minute precipitation data en-keyword=east-west difference of the Baiu precipitation kn-keyword=east-west difference of the Baiu precipitation END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=21 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A trial of lesson practice at the university on the variety of heavy rainfall characteristics based on the 10-minute precipitation data toward promoting the meteorological disaster prevention literacy kn-title=10分間降水量から大雨の特徴の多様性を捉える大学での授業の試み（防災気象リテラシー育成へ向けて） en-subtitle= kn-subtitle= en-abstract= kn-abstract=　In the disaster prevention education on the heavy rainfall around Japan, it is also important to promote the meteorological literacy on the seasonal and regional differences of their rainfall characteristics such as the convective rain or stratiform rain, together with their total amount of precipitation and their occurrence frequency. As the first step toward the above purpose, the present study made a lesson practice for the university students by utilizing the 10-minute precipitation data for the four heavy rainfall events, in which the types of the heavy rainfall (although all the cases examined in the lesson are relating to the deep convective clouds) are rather different from each other, such as the differences of the rainfall intensity at the peak time, short-period variation of the rainfall intensity and the persistency of the rainfall including the "not so intense rainfall". The reports by the students seem to perceive the different features among these events briefly, but the students' attention to how long the intense rainfall with short-period variation or "not so intense rainfall" lasted was not so sufficient. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域（理科） en-keyword=disaster prevention education kn-keyword=disaster prevention education en-keyword=variety of the heavy rainfall characteristics kn-keyword=variety of the heavy rainfall characteristics en-keyword=meteorological disaster prevention literacy kn-keyword=meteorological disaster prevention literacy en-keyword=use of the 10-minute precipitation data kn-keyword=use of the 10-minute precipitation data END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=9 end-page=19 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Petrological study of Sue ware from the Sabukaze kiln site, Okayama Prefecture kn-title=寒風古窯跡群須恵器の岩石学的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　The Sabukaze kiln site, a representative ancient tunnel-kiln site in the Kibi region, worked during the Asuka period (from early 7th century to early 8th century) to produce Sue ware including jars, cups, coffins, and ornamental tiles. To determine the provenance of the materials used for the Sue ware, we carried out petrological analyses of 13 Sue sherds, including optical microscopy, X-ray diffractometry, X-ray fluorescence spectroscopy, Raman spectroscopy, and electron-probe analysis. In spite of the difference of production time, all the Sue sherds show close similarities in modal proportion of mineral inclusions with dominant quartz and feldspar, and minor volcanic glass, in chemical compositions of feldspar and interstitial matrix, and in whole-sherd chemical composition. These similarities suggest that the paste materials of the Sabukaze Sue ware were commonly derived from weathered rhyolitic rocks and obtained from the same or neighboring mining site(s) located near the kiln site. en-copyright= kn-copyright= en-aut-name=ANAMITaiji en-aut-sei=ANAMI en-aut-mei=Taiji kn-aut-name=阿南太士 kn-aut-sei=阿南 kn-aut-mei=太士 aut-affil-num=1 ORCID= en-aut-name=NOZAKAToshio en-aut-sei=NOZAKA en-aut-mei=Toshio kn-aut-name=野坂俊夫 kn-aut-sei=野坂 kn-aut-mei=俊夫 aut-affil-num=2 ORCID= en-aut-name=KIMURAOsamu en-aut-sei=KIMURA en-aut-mei=Osamu kn-aut-name=木村理 kn-aut-sei=木村 kn-aut-mei=理 aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 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 affil-num=3 en-affil=Department of Archaeology, Osaka University kn-affil=大阪大学考古学研究室 en-keyword=Sabukaze kiln site kn-keyword=Sabukaze kiln site en-keyword=Sue ware kn-keyword=Sue ware en-keyword=provenance kn-keyword=provenance en-keyword=petrology kn-keyword=petrology END start-ver=1.4 cd-journal=joma no-vol=32 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=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Microtremor exploration in Kojima Bay area, Okayama Plain kn-title=岡山平野児島湾岸部での微動アレイ探査 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This report describes microtremor array observations conducted at two sites for deep exploration and three sites for shallow exploration around Kojima Bay area in the southern Okayama Plain.

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=61 cd-vols= no-issue= article-no= start-page=(59) end-page=(74) dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On Cen Shen’s Guozhou Period: His Mental State and Poetic Expression kn-title=?州期の岑参について ―― 心境と詩的表現 ―― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KUROSEKanako en-aut-sei=KUROSE en-aut-mei=Kanako kn-aut-name=黒瀬加那子 kn-aut-sei=黒瀬 kn-aut-mei=加那子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=(39) end-page=(57) dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A List of and Introduction to Takato Family Documents from Kamogata Village, Asakuchi District, Bicchu Province kn-title=備中国浅口郡鴨方村高戸家文書目録・史料紹介 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MASATSUGUKanako en-aut-sei=MASATSUGU en-aut-mei=Kanako kn-aut-name=政次加奈子 kn-aut-sei=政次 kn-aut-mei=加奈子 aut-affil-num=1 ORCID= en-aut-name=HONDAYoshiho en-aut-sei=HONDA en-aut-mei=Yoshiho kn-aut-name=本多佳穂 kn-aut-sei=本多 kn-aut-mei=佳穂 aut-affil-num=2 ORCID= en-aut-name=HIGASHINOMasanobu en-aut-sei=HIGASHINO en-aut-mei=Masanobu kn-aut-name=東野将伸 kn-aut-sei=東野 kn-aut-mei=将伸 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 affil-num=3 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=(21) end-page=(38) dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On Ten-nyo（ Heavenly Maidens） with Wings, Part 14: Feathered Robes on Taisho and Early Showa Stages kn-title=「有翼の天女図」十四考 ― 大正・昭和初期の舞台の羽衣 ― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TATSUNOYuko en-aut-sei=TATSUNO en-aut-mei=Yuko kn-aut-name=龍野有子 kn-aut-sei=龍野 kn-aut-mei=有子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=175 end-page=193 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Career Transitions of Lower-Ranking Officials in the Northern Dynasties after the Late Taihe Period of the Northern Wei: An Analysis Based on Epitaphs kn-title=墓誌から見た北魏太和後令以後の北朝下位官の遷転 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SUNQIAN en-aut-sei=SUN en-aut-mei=QIAN kn-aut-name=孫倩 kn-aut-sei=孫 kn-aut-mei=倩 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=155 end-page=174 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Does Environmental Spending Reduce Firm Risk? Evidence from Japanese Companies kn-title=環境支出は企業リスクを軽減するのか？日本企業の実証分析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This study examines how environmental conservation costs (ECC) affects firm risk, using changes in leverage ratios and earnings volatility as stand-ins for risk. This study evaluates the direct impact of ECC and its relationship to profitability (ROA) using panel data of Japanese companies from 2010 to 2022 and Pooled OLS regression models. The results demonstrate the risk-mitigating function of sustainability investments by showing that, although independent ECC have little direct significance, their interaction with firm profitability dramatically lowers earnings volatility and leverage instability. These findings underscore the economic value of environmental strategies, suggesting that incorporating profitability considerations into sustainability practices enhances operational stability and reduces risk exposure. To help policymakers, investors, and corporate managers strike a balance between sustainability and financial performance, this study contributes to the growing body of research on the relationship between the environment and finance. en-copyright= kn-copyright= en-aut-name=NAZIRYUSRA en-aut-sei=NAZIR en-aut-mei=YUSRA kn-aut-name=ナジールユスラ kn-aut-sei=ナジール kn-aut-mei=ユスラ aut-affil-num=1 ORCID=

thermoelectric semimetal Ta2PdSe6 with a large thermoelectric power factor and giant Peltier conductivity by means of angle-resolved photoemission spectroscopy (ARPES). The ARPES spectra reveal the coexistence of a sharp hole band with a light electron mass and a broad electron band with a relatively heavy electron mass, which originate from different quasi-one-dimensional (Q1D) chains in Ta2PdSe6. Moreover, the electron band around the Brillouin-zone (BZ) boundary shows a replica structure with respect to the energy originating from plasmonic polarons due to electron-plasmon interactions. The different scattering effects and interactions in each atomic chain lead to asymmetric transport lifetimes of carriers: a large Seebeck coefficient can be realized even in a semimetal. Our findings pave the way for exploring the thermoelectric materials in previously overlooked semimetals and provide a new platform for low-temperature thermoelectric physics, which has been challenging with semiconductors. en-copyright= kn-copyright= en-aut-name=OotsukiDaiki en-aut-sei=Ootsuki en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakanoAkitoshi en-aut-sei=Nakano en-aut-mei=Akitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruokaUrara en-aut-sei=Maruoka en-aut-mei=Urara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HasegawaTakumi en-aut-sei=Hasegawa en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AritaMasashi en-aut-sei=Arita en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitamuraMiho en-aut-sei=Kitamura en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoribaKoji en-aut-sei=Horiba en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaTeppei en-aut-sei=Yoshida en-aut-mei=Teppei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TerasakiIchiro en-aut-sei=Terasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Present address: Department of Applied Physics, Nagoya University kn-affil= affil-num=3 en-affil=Present address: Department of Applied Physics, Nagoya University kn-affil= affil-num=4 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=5 en-affil=Research Institute for Synchrotron Radiation Science, Hiroshima University kn-affil= affil-num=6 en-affil=Present address: NanoTerasu Center, National Institutes for Quantum Science and Technology (QST) kn-affil= affil-num=7 en-affil=Present address: NanoTerasu Center, National Institutes for Quantum Science and Technology (QST) kn-affil= affil-num=8 en-affil=Graduate School of Human and Environmental Studies, Kyoto University kn-affil= affil-num=9 en-affil=Present address: Department of Applied Physics, Nagoya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=160 end-page=164 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=Verification of a Skin Electrical Impedance Model for Evaluating Indicators of Skin Barrier Function of Older Adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skin barrier function has been quantitatively evaluated through trans-epidermal water loss, which has been difficult to measure in clinical settings owing to environmental factors and the measurement time. The thickness and surface water content of the stratum corneum are important indicators of skin barrier function, and current methods for measuring these two indicators are also difficult to implement in clinical settings. Therefore, we developed a model based on skin electrical impedance to estimate the thickness and water content of the stratum corneum, enabling measurement and estimation of these two indicators in a short time. In this study, we verified this model implemented in a portable skin electrical impedance measurement device for estimating the thickness and surface water content of the stratum corneum of the skin in older adults. Thirty-four older individuals were studied. The measurement electrodes were placed in contact with the forearm skin, and an alternating signal of two frequencies was applied to measure the impedance, from which the thickness and surface water content of the stratum corneum were estimated in approximately 5 s. The correlation coefficients between the estimated and measured thickness and between the estimated and measured surface water content were 0.732 and 0.604, respectively. Furthermore, the root mean square errors of the residuals for the thickness and surface water content were 1.66 ?m and 3.50 points, respectively, indicating that the model accurately estimated the thickness and surface water content of the stratum corneum, even in the skin of older adults. en-copyright= kn-copyright= en-aut-name=UEHARAOsamu en-aut-sei=UEHARA en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FUNAKIYuya en-aut-sei=FUNAKI en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NAKAMURATakao en-aut-sei=NAKAMURA en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Medical Engineering Laboratory, ALCARE Co., Ltd. kn-affil= affil-num=2 en-affil=Medical Engineering Laboratory, ALCARE Co., Ltd. kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=older adults kn-keyword=older adults en-keyword=stratum corneum thickness kn-keyword=stratum corneum thickness en-keyword=stratum corneum surface water content kn-keyword=stratum corneum surface water content END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=3 article-no= start-page=e72040 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Overload on Imiquimod‐Induced Psoriasis Model Mice: A Basic Experimental Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: Psoriasis is a skin disorder complicated by arthritis and enthesitis.

However, details regarding the mechanisms linking pathogenesis and mechanical stress remain unclear. This study aimed to investigate the effect of strenuous exercise on the pathology of psoriasis using mouse models of imiquimod (IMQ)-induced psoriasis.
Methods: Twenty mice were randomly assigned to four groups: IMQ???TRED? (control), IMQ???TRED+ (treadmill running mice), IMQ?+?TRED? group (IMQ treated mice), and IMQ?+?TRED+ group (IMQ treated and treadmill running mice). The tissue sections from back skin and thymus were immunostained with antibodies against IL-17, IL-23, and γδ T cells. Shoulder sections were stained using hematoxylin and eosin, and Toluidine Blue and Picrosirius Red. Additionally, the shoulder tissue sections were immunostained with antibodies against TNF-α and matrix metalloproteinase (MMP)-13. Serum cytokine level was measured to evaluate systemic inflammation.
Results: Strenuous exercise exacerbated pathological changes associated with psoriasis, including increased γδ T cell infiltration and upregulated IL-17 and IL-23 expression in the skin, as well as enhanced γδ T cell development and IL-17 expression in the thymus. Although strenuous exercise did not further worsen the modified PASI scores, histological and immunological markers of inflammation were significantly enhanced. Serum levels of TNF-α and IL-17 were significantly elevated in IMQ-induced psoriasis model mice. Moreover, pathological changes induced by strenuous exercise were observed in the enthesis, including angiogenesis and upregulated expression of TNF-α and MMP-13.
Conclusion: This study revealed that strenuous exercise exacerbates pathological changes in IMQ-induced psoriasis model mice. en-copyright= kn-copyright= en-aut-name=FurutaniTomoki en-aut-sei=Furutani en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkedaAsahi en-aut-sei=Ikeda en-aut-mei=Asahi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MashimaKenta en-aut-sei=Mashima en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YukihiroNatsumi en-aut-sei=Yukihiro en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KusakabeSatoki en-aut-sei=Kusakabe en-aut-mei=Satoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry, and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Okayama University Medical School Faculty of Medicine kn-affil= affil-num=4 en-affil=Okayama University Medical School Faculty of Medicine kn-affil= affil-num=5 en-affil=Okayama University Medical School Faculty of Medicine kn-affil= affil-num=6 en-affil=Okayama University Medical School Faculty of Medicine Okayama Japan kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=enthesis kn-keyword=enthesis en-keyword=psoriasis kn-keyword=psoriasis en-keyword=strenuous exercise kn-keyword=strenuous exercise END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=e70168 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mechanosensitive Ion Channel PIEZO1 Suppresses BMP2-Induced Ossification of the Annulus Fibrosus Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Major cause of low-back pain is intervertebral disc degeneration (IVDD), with mechanical stress playing a crucial role in its progression. A mechanosensitive ion channel, PIEZO1, is involved in various musculoskeletal tissues, but its role in the annulus fibrosus (AF) remains unclear. This study aimed to elucidate the function of PIEZO1 in AF cells under mechanical stimulation.
Methods: Primary rat AF cells were subjected to cyclic tensile strain (CTS) at low (2%) and high (12%) strain levels to investigate strain-dependent effects on osteogenic gene expression. We evaluated the effects of Piezo1, Piezo2, and Trpv4 knockdown by RNA interference to identify the upstream mechanotransducer. Furthermore, PIEZO1 was activated using the agonist Yoda1, followed by RNA-sequencing analysis and evaluation of its effects on BMP2-induced osteogenesis in rat AF cells. We also examined the effects of Yoda1 in primary human AF cells.
Results: Low-strain CTS significantly suppressed osteogenic marker expression, which was not observed with high strain. Piezo1 knockdown reversed this suppression, whereas Piezo2 and Trpv4 had no effect. Piezo1 activation by Yoda1 produced similar anti-osteogenic effects in both rat and human AF cells. RNA sequencing revealed the enrichment of ossification and calcineurin signaling pathways in rat cells. Furthermore, Piezo1 activation inhibited BMP2-induced osteogenesis and nuclear translocation of p-Smad1/5/9.
Conclusions: Piezo1 maintains AF cell homeostasis under mechanical stress by suppressing osteogenic changes via calcineurin-mediated inhibition of BMP signaling, which may represent a novel therapeutic target for IVDD. en-copyright= kn-copyright= en-aut-name=ShitozawaHisakazu en-aut-sei=Shitozawa en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UedaMasataka en-aut-sei=Ueda en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakatoriRyo en-aut-sei=Takatori en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamashitaKazutaka en-aut-sei=Yamashita en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University 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, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=annulus fibrosus kn-keyword=annulus fibrosus en-keyword=calcification kn-keyword=calcification en-keyword=ossification kn-keyword=ossification en-keyword=PIEZO1 kn-keyword=PIEZO1 END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=111 end-page=126 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=Die Agrarstruktur in Sachsen im 19.

Using a balanced panel of 128 non-financial companies listed on the Tokyo Stock Exchange from 2010 to 2022, we manually collected firm-level ECC data based on the Ministry of the Environment, Japan's guidelines from sustainability reports and matched them with financial data from Compustat Global/S&P Capital IQ. Applying pooled ordinary least squares regression with firm-level clustered standard errors and winsorized variables, we examine two aspects of performance as measures of operating efficiency and profitability: asset turnover and profit margin. The results show that ECC is positively associated with asset turnover and profit margin, and that the effect is stronger in more profitable companies, substantiating the Resource-Based View that green practices generate competitiveness. These findings contribute to sustainability finance research by going beyond perceptual measures of environmental, social, and governance ratings, and measuring actual firm-level spending on environmental activities, thereby providing more nuanced insights into how environmental practices translate into actual financial performance. This study offers clear managerial and policy implications by showing that transparent environmental conservation costs improve disclosure quality and serve as a measure of improved efficiency and profitability. en-copyright= kn-copyright= en-aut-name=NazirYusra en-aut-sei=Nazir en-aut-mei=Yusra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TennojiyaTatsumasa en-aut-sei=Tennojiya en-aut-mei=Tatsumasa kn-aut-name=天王寺谷達将 kn-aut-sei=天王寺谷 kn-aut-mei=達将 aut-affil-num=2 ORCID= affil-num=1 en-affil=Doctoral student at Graduate school of humanities and social sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of humanities and social sciences, Okayama University kn-affil= en-keyword=Environmental Accounting kn-keyword=Environmental Accounting en-keyword=Environmental Conservation Cost, Operating Efficiency kn-keyword=Environmental Conservation Cost, Operating Efficiency en-keyword=Profitability kn-keyword=Profitability en-keyword=Asset Turnover kn-keyword=Asset Turnover en-keyword=Sustainability kn-keyword=Sustainability en-keyword=Japanese Manufacturing Companies kn-keyword=Japanese Manufacturing Companies en-keyword=Resource-Based View kn-keyword=Resource-Based View END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=41 end-page=91 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=Re-theorizing Consumer Behavior in the Age of Human?AI Coexistence: The AIBCBM Framework kn-title=AI 共生時代における消費者行動の再理論化―AIBCBM フレームワーク― en-subtitle= kn-subtitle= en-abstract=　This study aims to construct and present the AI-Based Consumer Behavior Model（AIBCBM） as a theoretical framework that systematically explains the tripartite interaction among companies, consumers, and AI in environments where AI intervenes from the pre-decision stage. First, it identifies the critical theoretical limitations of existing consumer behavior models, which fail to adequately address contemporary phenomena such as algorithmic exposure, recursive learning loops, and AI-mediated social influence. Building upon this, the study presents the AIBCBM （AI-Based Consumer Behavior Model）, which conceptualizes consumer behavior in the era of AI symbiosis as a tripartite cyclical structure involving“ business?AI?consumer.”
　In constructing the model, rather than oversimplifying complex reality, theoretical clarity and analytical tractability are ensured by separating it into a tripartite co-evolutionary structure model （Figure 2）, a behavioral process model illustrating the dynamics of behavior generation（Table 3）, a conceptual structure model（Figure 3）, and a behavioral typology model（Figure 4）. The theoretical contributions of this study are summarized in five points:
（1） redefining System 1 as a behavioral generation mechanism;
（2） redefining decision-making agents and power structures;
（3） theoretically modeling nonlinear, high-speed feedback loops in consumer behavior;
（4） Theoretical redefinition of non-consumption and JOMO as strategic behaviors grounded in well-being and human agency.
（5） reconceptualizing consumer behavior from a "decision-making model" to a "behavior generation model."
　Moreover, the duality highlighted in this study?where algorithm-driven utility enhancement and autonomy impairment can coexist?provides a new normative and theoretical evaluation framework for marketing strategies and policy design in the AI era. AIBCBM functions as a theoretical platform that integrates these perspectives, serving as a foundation for future theoretical development and empirical validation. In particular, AIBCBM is distinctive in positioning JOMO and non-consumption not as passive withdrawal from algorithmic environments, but as strategic behaviors through which consumers intentionally calibrate their distance from AI-constructed choice architectures to preserve human agency, well-being, and human-likeness.
　Finally, the proposed model serves as a theoretical coordinate framework that systematically connects firm-side AI design, algorithmic dynamics, and consumer agency and well-being, thereby bridging empirical inquiry and normative design in the age of AI co-existence. kn-abstract=　本研究は，AIが意思決定の前段階から介入する環境において，企業・消費者・AIの三者相互作用を体系的に説明する理論枠組みとして，Artificial Intelligence-Based Consumer Behavior Model（AIBCBM）を構築し，提示することを目的とする。まず，既存の消費者行動モデルが，アルゴリズム露出，再帰的学習ループ，AI媒介型社会的影響（Algorithmic Social Influence）といった現代的現象を十分に扱えないという決定的な理論的限界を明らかにする。そのうえで，AI共生時代における消費者行動を，「企業−AI−消費者」の三者循環構造として捉えるAIBCBMを提示する。
　モデル構築に際しては，複雑な現実を過度に単純化するのではなく，三者共進化構造モデル（図２），行動生成の動態を示す行動プロセスモデル（表３），概念構造モデル（図３），行動類型モデル（図４）に分離することで，理論的明瞭性と分析可能性を確保した。本研究の理論的貢献は，@System １を行動生成メカニズムとして再定義した点，A意思決定主体と権力構造を再定義した点，B消費者行動における非線形・高速フィードバックループを理論化した点，C非消費やJOMOを，幸福と主体性に根ざした戦略的行動として理論的に再定義した点，D消費者行動を「意思決定モデル」から「行動生成モデル」へ理論的に転換した点に集約される。さらに，本研究が提示する，アルゴリズムによる効用の向上と自律性の毀損が併存しうるという二面性は，AI時代におけるマーケティング戦略および政策設計に対して，規範的かつ理論的な新たな評価軸を提供する。AIBCBMは，これらの視座を統合する理論的プラットフォームとして，今後の実証研究に向けた基盤として機能する。とりわけ， AIBCBMは，JOMOや非消費行動を，アルゴリズム環境からの受動的撤退ではなく，AIによって構築された選択環境との距離を意図的に調整し，人間らしさ（人間としての主体性やウェルビーイング）を保持するための戦略的行動として位置づける点に独自性を有する。さらに本モデルは，AI設計（企業側）・アルゴリズム動態（AI側）・主体性とウェルビーイング（Well-being）（消費者側）を同一枠組みで接続することで，AI共生時代の実証研究と規範設計を架橋する理論的座標軸を確立する。 en-copyright= kn-copyright= en-aut-name=ShazadigulSawut en-aut-sei=Shazadigul en-aut-mei=Sawut kn-aut-name=夏扎提古?沙吾提 kn-aut-sei=夏扎提古? kn-aut-mei=沙吾提 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=行動生成モデル (Behavior Generation Model) kn-keyword=行動生成モデル (Behavior Generation Model) en-keyword=人間−AIの共同主体性 (Human-AI Co-agency/Shared Agency) kn-keyword=人間−AIの共同主体性 (Human-AI Co-agency/Shared Agency) en-keyword=アルゴリズム的選択環境 (Algorithmic Choice Architecture) kn-keyword=アルゴリズム的選択環境 (Algorithmic Choice Architecture) en-keyword=非消費／意図的な非使用 (Non-consumption/Intentional Non-use) kn-keyword=非消費／意図的な非使用 (Non-consumption/Intentional Non-use) en-keyword=再帰的学習ループ (Recursive Learning Loops) kn-keyword=再帰的学習ループ (Recursive Learning Loops) END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=11 end-page=40 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=Network Analysis of Interregional Information Exchange: A Study in the Takahashi River Basin Area kn-title=地域間での情報交流に関するネットワーク分析：高梁川流域圏での調査による en-subtitle= kn-subtitle= en-abstract=　This paper conducted network analysis focusing on information exchange among participating entities in the "Takahashi River Basin Economic Growth Strategy Council," operating within Okayama Prefecture's "Takahashi River Basin Core City Area." The Takahashi River Basin Collaborative Core City Area（ Takahashi River Basin Area）is a collaborative core city area encompassing ten municipalities located around the Takahashi River in Okayama Prefecture: Niimi City, Takahashi City, Soja City, Hayashima Town, Kurashiki City, Yakage Town, Ibara City, Asakuchi City, Satosho Town, and Kasaoka City. For the network analysis within the Takahashi River Basin Area, projects implemented within the area were classified into eight categories. A questionnaire survey was conducted regarding information exchange among participating entities for each project. Network metrics included calculating centrality indices（ degree centrality and betweenness centrality） for each project, along with density, transitivity, and reciprocity. By project type, tourism projects exhibited the densest network structure for information exchange. From a network perspective, tourism projects can be considered the most actively pursued initiative within the Takahashi River Basin area. Furthermore, across all projects, centrality indicators for specific administrative bodies and regional economic organizations, such as chambers of commerce and industry, generally showed high values. This clearly indicates their function as hubs for information exchange and as entities concentrating or dispersing information within the network. Based on the results of network analysis, two recommendations for future regional development in the Takahashi River Basin were proposed from a network perspective. The first is to aim for dense networks across all businesses by sharing the roles of information exchange hubs and information concentration/distribution entities among the entities involved, depending on the business. The second is to aim for a dense network overall by eliminating entities that are not participating at all in the Takahashi River Basin's information exchange network. kn-abstract=　本稿では，岡山県の「高梁川流域連携中枢都市圏」で2014年から開催されている「高梁川流域経済成長戦略会議」における参加主体間の情報交流についてのネットワーク分析を行った。高梁川流域連携中枢都市圏（高梁川流域圏）とは，岡山県高梁川周辺に位置する現在の新見市，高梁市，総社市，早島町，倉敷市，矢掛町，井原市，浅口市，里庄町，笠岡市の10自治体が参加している連携中枢都市圏である。高梁川流域圏におけるネットワーク分析に際しては，同圏域内で展開されている事業を８つに分類し，それぞれの事業に関する参加主体間の情報交流についてアンケート調査を行った。ネットワーク指標については事業ごとに次数中心性と媒介中心性の中心性指標を，また事業別に密度，推移性，相互性を算出した。事業別にみると，観光事業についての情報交流が最も密なネットワーク構造をしており，ネットワークの視点では観光事業が高梁川流域圏内で最も勢力的に行われている事業といえる。また全事業において特定の行政主体や商工会議所をはじめとする地域経済団体等の中心性指標が全体的に大きな値をとっており，ネットワークにおいて情報交流のハブや情報の集中・分散主体として機能していることが明らかになった。分析結果を踏まえ，ネットワークの視点から高梁川流域圏の今度の地域振興について２点提言した。１つは事業によって情報交流のハブや情報の集中・分散主体を主体間で分担することによって，すべての事業で密なネットワークを築くことを目指すことである。もう１つは高梁川流域圏の情報交流ネットワークに全く参加していない主体をなくすことで，全体的に密なネットワークを目指すことである。 en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= en-aut-name=YokotaNatsumi en-aut-sei=Yokota en-aut-mei=Natsumi kn-aut-name=横田夏実 kn-aut-sei=横田 kn-aut-mei=夏実 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=下関市役所 END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=1 end-page=10 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=The 1998 Amendment to the Foreign Exchange and Foreign Trade Control Act and the Classification of Income from Gains and Losses on Foreign Currency Transactions: How Did the Amendment of 1998 Affect Income Classification? kn-title=1998年の外国為替及び外国貿易管理法改正と 外国通貨の譲渡による損益の所得区分 ―1998年の法改正は所得区分にどのような影響を与えたのか― en-subtitle= kn-subtitle= en-abstract=　The 1998 amendment to the Foreign Exchange and Foreign Trade Control Act（ subsequently renamed the Foreign Exchange and Foreign Trade Act） liberalized foreign exchange transactions, which had previously been restricted in principle to authorized foreign exchange banks. This amendment allowed all companies and individuals to freely conduct such transactions.
　This paper first examines the basis for the tax authorities' view that "gains or losses from foreign currency transfers constitute miscellaneous income," drawing from government witness testimony in the Diet and the Tokyo District Court judgement of March 9, 2023. Then it concludes that the 1998 legal amendment, by enabling anyone to freely conduct foreign currency transactions both internationally and domestically, transformed foreign currency into a means of payment functioning as a measure of value. Consequently, it became impossible to conceptualize foreign currency as an asset subject to appreciation or depreciation, leading to the reclassification of income from its transfer from capital gains to miscellaneous income. kn-abstract=　1998年の外国為替及び外国貿易管理法の改正（以降，外国為替及び外国貿易法に改名）により，それまで外国為替公認銀行に原則として限られていた外国為替取引が，あらゆる企業及び個人に解放され，自由に行うことができるようになった。
　本稿は，まず課税当局の「外国通貨の譲渡による損益は雑所得に該当する」との見解の判断根拠を，国会における政府参考人答弁及び東京地裁令和５年３月９日判決から読み解き，そのうえで，1998年の法改正により外国通貨取引が対外及び国内において何人も自由に行うことができるようになったことから，外国通貨は支払手段として言わば価値の尺度として機能するようになり，資産の値上がり，値下がりを観念することができなくなった結果として，その譲渡による所得区分が譲渡所得から雑所得へと変化したとの結論を導くものである。 en-copyright= kn-copyright= en-aut-name=NakagawaYoshiyuki en-aut-sei=Nakagawa en-aut-mei=Yoshiyuki kn-aut-name=中川吉之 kn-aut-sei=中川 kn-aut-mei=吉之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=9 article-no= start-page=e772 end-page=e780 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=Aging of the tricuspid valve annulus detected by photon-counting detector computed tomography: Importance of aortic root compression on occurrence of arrhythmias en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The aortic root compresses the heart in elderly patients, potentially influencing the conduction system and causing atrial tachyarrhythmias. However, actual anatomic alterations in the right side of the heart because of aortic root compression have not yet been fully evaluated.
Objective This study aimed to elucidate the alterations in the tricuspid valve annulus (TVA) caused by aortic root compression using a 3-dimensional endoscopic view of the heart constructed by photon-counting detector computed tomography, an emerging medical technology.
Methods We analyzed 147 consecutive patients who underwent photon-counting detector computed tomography at our institute after excluding those with diseases that directly influenced the right side of the heart.
Results Aortic root compression caused significant TVA deformation. We defined severe TVA compression as the length of the TVA compressed by the aortic root ?80% of the major axis of the TVA. Severe compression was more prevalent in elderly patients (age ?75 years [44%]; P < .01). The distance between the membranous septum and ostium of the coronary sinus was shortened, whereas the cavotricuspid isthmus was elongated in older patients. The regression analysis identified aging as a significant contributor to TVA compression. The short minor and long major axes of the TVA, incidence of atrial tachyarrhythmias (74% vs 45%; P < .01), and atrioventricular conduction disturbances (35% vs 15%; P < .01) were more frequently observed in patients with severe compression.
Conclusion Aortic root compression deforms the TVA and alters the anatomic relationship between the atrioventricular conduction system and the cavotricuspid isthmus. Therefore, aortic root compression may contribute to the occurrence of atrial tachyarrhythmias and conduction disturbances in older patients. en-copyright= kn-copyright= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaseSatoshi en-aut-sei=Nagase en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoYoshihisa en-aut-sei=Morimoto en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaTakuro en-aut-sei=Masuda en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UeokaAkira en-aut-sei=Ueoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AsadaSaori en-aut-sei=Asada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Cardiovascular Therapeutics, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry 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 Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=11 en-affil=Department of Cardiovascular Therapeutics, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= en-keyword=Tricuspid valve annulus kn-keyword=Tricuspid valve annulus en-keyword=Aortic root kn-keyword=Aortic root en-keyword=Photon-counting detector computed tomography kn-keyword=Photon-counting detector computed tomography en-keyword=Atrial tachyarrhythmia kn-keyword=Atrial tachyarrhythmia en-keyword=Conduction abnormality kn-keyword=Conduction abnormality END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue= article-no= start-page=101798 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alcohol consumption, smoking, and the implications of their cessations for field carcinogenesis in the esophagus: a 10-year prospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Alcohol and tobacco are established carcinogens, which promote field carcinogenesis for esophageal squamous cell carcinoma (ESCC). This study aimed to evaluate the long-term effects of alcohol and tobacco cessations, and background mucosal status, on risk for metachronous ESCC (mESCC) after endoscopic resection (ER).
Methods This was a multicentre prospective cohort study of patients with intramucosal ESCC treated by ER. All participants received structured education on cessation, and underwent regular endoscopic surveillance. Patients were stratified by Lugol-voiding lesion (LVL) grade (A: none, B: 1?9, C: ?10). The impacts of alcohol and smoking cessation on field carcinogenesis were assessed.
Findings Among 331 enrolled patients, the median follow-up was 120 months (range: 1.3?176.9). The cumulative incidences of mESCC were 10.4%, 27.2%, and 61.8% in grades A, B, and C, respectively. An increment of 1 unit (22 g ethanol) of alcohol consumption and higher LVL grade independently increased the risk for mESCC. Alcohol or smoking cessation reduced this risk (hazard ratio [HR] 0.52, 95% confidence interval [CI]: 0.31?0.88; HR 0.44, 95% CI: 0.25?0.78, respectively), and combined cessation had the greatest impact (HR 0.21, 95% CI: 0.07?0.65). Complete cessation, rather than partial reduction, was necessary to achieve meaningful risk reduction.
Interpretation Alcohol and tobacco exposure, and a large number of LVL, are major determinants of mESCC. Complete cessation markedly reduces risk, underscoring the importance of behavioural interventions for secondary prevention of field carcinogenesis after ER. en-copyright= kn-copyright=

deformity, nucleophagy, and their autophagic secretion with extracellular vesicles in metastatic cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Matrix metalloproteinases (MMPs) are a family of zinc-dependent proteinases that cleave a plethora of substrates, including components of the extracellular matrix and cell-surface-associated proteins, as well as intracellular targets. MMPs have also been found in extracellular vesicles (EVs), such as exosomes. MMP-3 promotes tumor growth, epithelial-to-mesenchymal transition, genome instability, migration, invasion, and metastasis of cancer cells, and nuclear MMP-3 controls gene transcription. Intranuclear proteolysis by MMPs may significantly alter cancer progression. However, the nuclear substrates of MMP-3 have not been well investigated. In this study, we performed proteomic analyses to identify the nuclear substrates and EV proteins regulated by MMP-3. While rabidly metastatic colon cancer (LuM1) three-dimensionally cultured tumoroids secreted EVs containing 30 protein types, including Lamin A (LMNA), MMP-3, fibronectin (FN1), HSPA8 (Hsc70), β-actin (ACTB), and vimentin (VIM), CRISPR/Cas9-based knockout of MMP-3 reduced the secretion of these proteins in EVs. Notably, EV-bound cleaved Lamin secretion was confirmed by immunoelectron microscopy. Also, MMP-3 formed proteolytic dimers via its hemopexin-like repeat domains in nuclei. Many nuclear MMP-3-binding proteins, including Lamin A/C, histones, topoisomerases, and hnRNPs, were screened by co-immunoprecipitation followed by proteomics. Proteolytic MMP-3 overexpression generated a C-terminal 30-kDa fragment of Lamin A, whose cleavage site was defined via structural analysis. MMP-3 digestion of Lamin A induced nuclear deformity (atypia) required for cell migration in confined space. The cleaved Lamin A and MMP-3 were transported with autophagosomes (LC3B+), nucleophagosomes, and amphisomes (CD63?+?LC3B+) and co-secreted with EVs. Proteolytic MMP-3 also induced nuclear speckles of Lamin A, suggesting their roles in transcription and splicing. Clinical analysis revealed that high expressions of MMP3 and LMNA were significantly seen in head and neck squamous cell carcinoma (HNSC) than in the other 16 cancer types, and predicted poor prognosis of patients suffering from HNSC, pancreatic, rectum and lung adenocarcinomas at specific stages. Immunohistochemistry revealed that nuclear MMP-3 and cleaved Lamin were significantly higher expressed in stage IV metastatic HNSC cases than in stage I non-metastatic cases. Taken together, MMP3-cleavage of Lamin A induces nuclear deformity, nucleophagy, and their autophagic co-secretion with EVs in metastatic cancer. Also, high expression of MMP-3 and secretion of Lamin A can predict poor prognosis in multiple cancer types at specific stages. en-copyright= kn-copyright= en-aut-name=EguchiTakanori en-aut-sei=Eguchi en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TahaEman A. en-aut-sei=Taha en-aut-mei=Eman A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TiwariVikas en-aut-sei=Tiwari en-aut-mei=Vikas 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=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=XingLizi en-aut-sei=Xing en-aut-mei=Lizi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SogawaChiharu en-aut-sei=Sogawa en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkamotoKuniaki en-aut-sei=Okamoto en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=CalderwoodStuart K. en-aut-sei=Calderwood en-aut-mei=Stuart K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biochemistry, Faculty of Science, Ain Shams University kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Council of Scientific & Industrial Research-Indian Institute of Toxicological Research kn-affil= affil-num=5 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Food and Health Sciences, Faculty of Environmental Studies, Hiroshima Institute of Technology kn-affil= affil-num=9 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Division of Molecular and Cellular Biology, Department of Radiation Oncology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= en-keyword=Lamin A (LMNA) kn-keyword=Lamin A (LMNA) en-keyword=Matrix metalloprotease (MMP) kn-keyword=Matrix metalloprotease (MMP) en-keyword=Proteolysis kn-keyword=Proteolysis en-keyword=Extracellular vesicle (EV) kn-keyword=Extracellular vesicle (EV) en-keyword=Exosome kn-keyword=Exosome en-keyword=Autophagy kn-keyword=Autophagy en-keyword=Amphisome kn-keyword=Amphisome en-keyword=Proteome kn-keyword=Proteome en-keyword=Nuclear deformity kn-keyword=Nuclear deformity en-keyword=Migration kn-keyword=Migration en-keyword=Metastatic cancer kn-keyword=Metastatic cancer en-keyword=Head and neck squamous cell carcinoma kn-keyword=Head and neck squamous cell carcinoma en-keyword=Colorectal cancer kn-keyword=Colorectal cancer END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=27 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the incidence of infusion-related reactions by obinutuzumab and the dose of corticosteroid as premedication: a multicenter retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Premedication with corticosteroids is recommended for prophylaxis against infusion-related reactions (IRRs) caused by obinutuzumab despite a lack of solid evidence regarding the dose of corticosteroids.
Methods The incidence rates of IRR in the high-dose and low-dose corticosteroid groups were investigated and compared using Student’s t-test.Univariable and multivariable logistic regression analyses were performed on patients to explore the risk of developing IRRs with obinutuzumab.
Results The incidence of IRRs in the high-dose and low-dose corticosteroid groups at the initial administration of obinutuzumab was 27.0% (41/152) and 48.4% (31/64), respectively, indicating that the high-dose group had a lower incidence of IRRs (p?=?0.002). The incidence of IRRs at the initial administration of obinutuzumab was significantly associated with the administration of first-generation histamine 1 receptor antagonist (OR?=?3.31, 95% CI: 1.16?9.47; reference: second-generation histamine 1 receptor antagonist), hydrocortisone (OR?=?7.21, 95% CI: 1.57?33.15; reference: dexamethasone), and methylprednisolone (OR?=?3.99, 95% CI :1.13?14.10; reference: dexamethasone), although no association was found with the lower dose of corticosteroids.
Conclusions Although no association was found between corticosteroid dosage and IRR when considering multiple factors, dexamethasone may be a better option than hydrocortisone or methylprednisolone for preventing IRR. Additionally, second-generation H1-receptor antagonists may be a better option than first-generation drugs. Certain combinations of premedications may influence infusion reaction incidence. en-copyright= kn-copyright= en-aut-name=OhtsuboTatsuya en-aut-sei=Ohtsubo en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoKazuhiro en-aut-sei=Yamamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatumotoSaori en-aut-sei=Matumoto en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoKaori en-aut-sei=Ito en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasaYuzuka en-aut-sei=Sasa en-aut-mei=Yuzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomishimaKosuke en-aut-sei=Tomishima en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DoteSatoshi en-aut-sei=Dote en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakiharaKatuya en-aut-sei=Makihara en-aut-mei=Katuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WakasugiYoshinori en-aut-sei=Wakasugi en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuieTsutomu en-aut-sei=Mitsuie en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamagiwaKouhei en-aut-sei=Yamagiwa en-aut-mei=Kouhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SatoKazuo en-aut-sei=Sato en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HasegawaHiroki en-aut-sei=Hasegawa en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=UoshimaNobuhiko en-aut-sei=Uoshima en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KitahiroYumi en-aut-sei=Kitahiro en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TomoganeKanji en-aut-sei=Tomogane en-aut-mei=Kanji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Pharmacy, Japanese Red Cross Kyoto Daini Hospital kn-affil= affil-num=2 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pharmacy, Japanese Red Cross Osaka Hospital kn-affil= affil-num=4 en-affil=Faculty of Pharmacy, Meijo University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Kindai University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Japanese Red Cross Kyoto Daiichi Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Kyoto-Katsura Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Yodogawa Christian Hospital kn-affil= affil-num=9 en-affil=Department of Pharmacy, Shiga University of Medical Science Hospital kn-affil= affil-num=10 en-affil=Department of Pharmacy, Japanese Red Cross Otsu Hospital kn-affil= affil-num=11 en-affil=Department of Pharmacy, Saiseikai Shiga Hospital kn-affil= affil-num=12 en-affil=Department of Pharmacy, Japan Baptist Hospital kn-affil= affil-num=13 en-affil=Department of Pharmacy, Rakuwakai Otowa Hospital kn-affil= affil-num=14 en-affil=Department of Hematology, Japanese Red Cross Kyoto Daini Hospital kn-affil= affil-num=15 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=16 en-affil=Department of Pharmacy, Japanese Red Cross Kyoto Daini Hospital kn-affil= en-keyword=Obinutuzumab kn-keyword=Obinutuzumab en-keyword=Infusion-related reaction kn-keyword=Infusion-related reaction en-keyword=Premedication kn-keyword=Premedication en-keyword=Corticosteroids kn-keyword=Corticosteroids en-keyword=Histamine 1 receptor antagonists kn-keyword=Histamine 1 receptor antagonists END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=32 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-world comparative effectiveness of sarilumab versus Janus kinase inhibitors as monotherapy in rheumatoid arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Sarilumab (SAR), an interleukin-6 receptor inhibitor (IL-6Ri), and Janus kinase inhibitors (JAKi) are approved options for rheumatoid arthritis (RA) when methotrexate (MTX) cannot be used. Real-world evidence for MTX-free monotherapy remains limited.
Methods: We conducted a multicenter retrospective cohort study of RA patients receiving SAR or JAKi as MTX-free monotherapy. To reduce confounding, 1:1 propensity score matching was performed in the overall cohort (n?=?252, 126 per group) and separately within treatment-line strata: Phase 2 first-line biologic/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs: 45 per group), Phase 3 second-line b/tsDMARDs (53 per group), and Phase 3???third-line b/tsDMARDs (47 per group). Outcomes over 12 months included drug retention, change in Clinical Disease Activity Index (CDAI), glucocorticoid (GC) tapering and discontinuation, low disease activity (LDA, CDAI???10), and safety profiles. Predictors of LDA were evaluated with logistic regression. This multicenter real-world.
Results: Across matched strata by prior b/tsDMARDs, retention and CDAI change did not differ significantly between SAR and JAKi through 12 months. When classified by cause, adverse events (AEs)-related discontinuation was higher with JAKi, yielding lower AE-specific retention. Both groups demonstrated GC sparing overtime, with a greater increase in GC discontinuation for SAR than for JAKi in Phase 2. Baseline predictors of achieving LDA at 12 months included higher C-reactive protein (CRP) and platelet count (Plt) in both groups, with additional associations of younger age and lower hemoglobin (Hb) in the SAR. In safety analyses, overall AEs were less frequent with SAR than with JAKi, driven by lower risks of infection including herpes zoster, while other categories were similarly infrequent.
Conclusion: SAR and JAKi showed no statistically significant differences in 12-month retention or disease control in MTX-free monotherapy settings. Higher CRP and Plt with lower Hb, particularly in younger patients, identified better response to SAR and support biomarker guided selection between IL-6Ri and JAKi. In Phase 2, GC discontinuation with SAR suggests a practical strategy to reduce AEs while maintaining efficacy. Prospective studies should validate these findings and define actionable thresholds. en-copyright= kn-copyright= en-aut-name=NozakiYuji en-aut-sei=Nozaki en-aut-mei=Yuji kn-aut-name= kn-aut-sei=

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=

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=115 cd-vols= no-issue=3 article-no= start-page=117345 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of the cefazolin inoculum effect in blood culture-isolated methicillin-susceptible Staphylococcus aureus strains: A Japanese multicenter study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Cefazolin inoculum effect (CInE) is a microbiological phenomenon where the MIC of cefazolin against methicillin-susceptible Staphylococcus aureus (MSSA) strains increases with higher bacterial volumes.
Method: We retrospectively investigated the prevalence and characteristics of the CInE among MSSA strains isolated from blood cultures at three Japanese hospitals. The collected isolates were screened for blaZ using PCR, and the cefazolin minimum inhibitory concentration (MIC) for the blaZ-positive MSSA isolates was measured at standard and high inoculum volumes. CInE-positive MSSA strains were defined as those with a cefazolin MIC ?16 μg/mL at 107 CFU/mL and ?8 μg/mL at 105 CFU/mL. In these blaZ-positive strains, we performed blaZ typing and tested a modified nitrocefin-based rapid examination to detect the CInE.
Results: We collected 329 MSSA strains isolated from blood cultures. Of these, 96 (29.2%) were positive for the blaZ gene, with the following genotypes: type A (15, 15.6%), type B (3, 3.1%), type C (77, 80.2%), type D (0, 0.0%), and non-type (1, 1.0%). Among 96 blaZ-positive MSSA isolates, 11 exhibited the CInE, all of which harbored blaZ type A. The rapid nitrocefin test detected CInE positivity with high sensitivity (100%), specificity (94.1%), and diagnostic accuracy (94.8%).
Conclusion: This study highlighted the low prevalence of CInE-presenting MSSA isolates in Japan. When the cefazolin MIC is ?1 μg/mL or the penicillin G MIC is ?0.25 μg/mL, the rapid nitrocefin test may be useful for considering the CInE in patients with high bacterial volume MSSA 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=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaSakura en-aut-sei=Ogawa en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoyanagiNorihito en-aut-sei=Koyanagi en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoYuji en-aut-sei=Ito en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoganemaruHiroshi en-aut-sei=Koganemaru en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaAtsushi en-aut-sei=Yoshida en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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 Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Clinical Laboratory, Chutoen General Medical Center kn-affil= affil-num=7 en-affil=Department of General Internal Medicine, Chutoen General Medical Center kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Tokyo Metropolitan Institute for Geriatrics and Gerontology kn-affil= affil-num=9 en-affil=Department of Infectious Diseases, Tokyo Metropolitan Institute for Geriatrics and Gerontology kn-affil= affil-num=10 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=blaZ kn-keyword=blaZ en-keyword=Cefazolin inoculum effect kn-keyword=Cefazolin inoculum effect en-keyword=Methicillin-susceptible Staphylococcus aureus kn-keyword=Methicillin-susceptible Staphylococcus aureus en-keyword=Nitrocefin rapid test kn-keyword=Nitrocefin rapid test en-keyword=β-lactamase kn-keyword=β-lactamase END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=5 article-no= start-page=5944 end-page=5955 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Discovery of Thermal Sensitizers That Inhibit Heat-Induced SAFB Granule Formation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hyperthermia is a minimally invasive cancer treatment based on heat stress-induced apoptosis. Its therapeutic efficacy, however, is often limited by tumor heterogeneity and acquired thermotolerance. Therefore, combination strategies involving hyperthermia and chemotherapy have been developed to enhance the therapeutic efficacy. Previously, we showed that SB366791 enhanced heat-induced apoptosis by inhibiting heat stress-induced scaffold attachment factor B (SAFB) granule formation, although its proapoptotic activity was insufficient. Therefore, we screened to identify novel compounds that enhance heat-induced apoptosis by suppressing SAFB granule formation. We identified four hit compounds that inhibited SAFB granule formation, all exhibiting thermal enhancement ratios > 1.0─that significantly enhanced heat-induced apoptosis efficiency. Additionally, the tumor volume in mice treated with a combination of Z19024498 and hyperthermia was significantly smaller than that in mice treated with hyperthermia or Z19024498. These results indicate that the identified compounds, specifically Z19024498, have potential as thermal sensitizers for hyperthermia therapy. en-copyright= kn-copyright= en-aut-name=FurutaniYuji en-aut-sei=Furutani en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimasakiNatsuki en-aut-sei=Shimasaki en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaRiko en-aut-sei=Yamada en-aut-mei=Riko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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= affil-num=1 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=165 cd-vols= no-issue= article-no= start-page=105344 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Local immune response induced by intra-fin antigen injection in Japanese medaka (Oryzias latipes) is a useful model for immunological studies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Teleost fishes play a pivotal role in advancing our understanding of immune system evolution because they retain the ancient characteristics of vertebrate immunity, encompassing both innate and adaptive immune systems. Among these, innate immunity plays a critical role in fish as the first line of defense, coordinating rapid responses to pathogen infections. However, the lack of fish-specific immunological methodologies has limited progress in elucidating fish immune mechanisms. To better understand how the innate immune response develops and resolves in fish, detailed observation and integrative analysis of leukocytes at multiple time points is necessary. In the present study, an intra-fin injection method for observing local immune responses in Japanese medaka (Oryzias latipes) was tested and optimized to analyze the progression of zymosan-induced innate immune responses. Zymosan-injected medaka showed a rapid immune response characterized by leukocyte recruitment and phagocytosis. Using TG(FmpxP:mCherry) transgenic medaka with mCherry fluorescence driven by myeloperoxidase (mpx) promoter, granulocyte chemotaxis towards the site of zymosan entry was successfully visualized. The rapid increase in tumor necrosis factor α (tnfa), interleukin-1β (il1b), interleukin-6 (il6), and CXC motif chemokine ligand 8 (cxcl8) expressions in zymosan-injected anal fins provided a molecular basis for the visualized tissue-specific cellular response. Our study underscores the dynamic orchestration of immune components during the innate immune response in Japanese medaka and highlights their potential as a promising model for immunological research. en-copyright= kn-copyright= en-aut-name=RyuTsukasa en-aut-sei=Ryu en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshinoMizuki en-aut-sei=Yoshino en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TseWilliam Ka Fai en-aut-sei=Tse en-aut-mei=William Ka Fai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IguchiTaisen en-aut-sei=Iguchi en-aut-mei=Taisen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumarAnu en-aut-sei=Kumar en-aut-mei=Anu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SomamotoTomonori en-aut-sei=Somamoto en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakaoMiki en-aut-sei=Nakao en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OginoYukiko en-aut-sei=Ogino en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=2 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biology, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Developmental Disorders and Toxicology, Kyushu University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Nanobioscience, Yokohama City University kn-affil= affil-num=6 en-affil=Commonwealth Scientific and Industrial Research Organisation, CSIRO Environment kn-affil= affil-num=7 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=8 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=9 en-affil=Center for Promotion of International Education and Research, Faculty of Agriculture, Kyushu University kn-affil= en-keyword=Chemotaxis kn-keyword=Chemotaxis en-keyword=Local immunity kn-keyword=Local immunity en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Innate immunity kn-keyword=Innate immunity en-keyword=Phagocytosis kn-keyword=Phagocytosis en-keyword=Zymosan kn-keyword=Zymosan END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=3 article-no= start-page=e198959 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagen-binding C-type natriuretic peptide enhances chondrogenesis and osteogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=C-type natriuretic peptide (CNP) is known to promote chondrocyte proliferation and bone formation; however, CNP’s extremely short half-life necessitates continuous intravascular administration to achieve bone-lengthening effects. Vosoritide, a CNP analog designed for resistance to neutral endopeptidase, allows for once-daily administration. Nonetheless, it distributes systemically rather than localizing to target tissues, which may result in adverse effects such as hypotension. To enhance local drug delivery and therapeutic efficacy, we developed a potentially novel synthetic protein by fusing a collagen-binding domain (CBD) to CNP, termed CBD-CNP. This fusion protein exhibited stability under heat conditions and retained the collagen-binding ability and bioactivity as CNP. CBD-CNP localized to articular cartilage in fetal murine tibiae and promoted bone elongation. Spatial transcriptomic analysis revealed that the upregulation of chondromodulin expression may contribute to its therapeutic effects. Treatment of CBD-CNP mixed with collagen powder to a fracture site of a mouse model increased bone mineral content and bone volume compared with CNP-22. Intraarticular injection of CBD-CNP to a mouse model of knee osteoarthritis suppressed subchondral bone thickening. By addressing the limitations of CNP’s rapid degeneration, CBD-CNP leverages its collagen-binding capacity to achieve targeted, sustained delivery in collagen-rich tissues, offering a promising strategy for enhancing chondrogenesis and osteogenesis. en-copyright= kn-copyright= en-aut-name=HiraiKenta en-aut-sei=Hirai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawamuraKenta en-aut-sei=Sawamura en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EsakiRyusaku en-aut-sei=Esaki en-aut-mei=Ryusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkushaYuka en-aut-sei=Okusha en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaEriko en-aut-sei=Aoyama en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoHiroki en-aut-sei=Saito en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaKentaro en-aut-sei=Uchida en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MimaTakehiko en-aut-sei=Mima en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ImagamaShiro en-aut-sei=Imagama en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsushitaMasaki en-aut-sei=Matsushita en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HosonoYasuyuki en-aut-sei=Hosono en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=9 en-affil=Department of Medical Technology, Faculty of Health Sciences, Ehime Prefectural University of Health Sciences kn-affil= affil-num=10 en-affil=Department of Biochemistry and Molecular DentistryBacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=2 article-no= start-page=199 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Targeting the Gut in Sepsis: Therapeutic Potential of Medical Gases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sepsis is a life-threatening condition characterized by a dysregulated host response to infection, often resulting in multiorgan dysfunction. Among affected systems, the gastrointestinal tract plays a central role in sepsis progression by promoting systemic inflammation through impaired barrier function, immune imbalance, and microbiome alterations. Recent research has identified selected medical gases and gasotransmitters as promising therapeutic candidates for preserving gut integrity in sepsis. In particular, hydrogen, carbon monoxide, and hydrogen sulfide exhibit antioxidative, anti-inflammatory, and cytoprotective properties. These gases act through defined molecular pathways, including activation of Nrf2, inhibition of NF-κB, and preservation of tight junction integrity, thereby supporting intestinal barrier function. In addition, they influence immune cell phenotypes and autophagy, with indirect effects on the gut microbiome. Although most supporting evidence derives from preclinical models, translational findings and emerging safety data highlight the potential of gut-targeted gas-based strategies. This review summarizes current mechanistic and translational evidence for gut-protective medical gases in sepsis and discusses their integration into future organ-specific and mechanism-based therapeutic approaches. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=carbon monoxide kn-keyword=carbon monoxide en-keyword=gastrointestinal tract kn-keyword=gastrointestinal tract en-keyword=gut kn-keyword=gut en-keyword=hydrogen kn-keyword=hydrogen en-keyword=hydrogen sulfide kn-keyword=hydrogen sulfide en-keyword=sepsis kn-keyword=sepsis en-keyword=septic shock kn-keyword=septic shock 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=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-world six-month outcomes after switching from aflibercept 2 mg to aflibercept 8 mg for neovascular age-related macular degeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To investigate 6-month outcomes in eyes with neovascular age-related macular degeneration (nAMD) switched from intravitreal aflibercept 2 mg to intravitreal aflibercept 8 mg.
Study design Retrospective observational study.
Methods We reviewed records of consecutive nAMD eyes switched from aflibercept 2 mg to 8 mg. In eyes continuing aflibercept 8 mg, best-corrected visual acuity (BCVA), treatment intervals, and anatomical/exudative parameters were evaluated at 6 months. In eyes that could not continue, reasons for discontinuation were examined.
Results Forty-four eyes from 44 patients were included. At 6 months, 35 eyes (79.5%) continued and 9 (20.5%) discontinued aflibercept 8 mg. Discontinuing eyes had significantly shorter pre-switch treatment intervals and more frequent prior therapies than continuing eyes. In the continuation group, BCVA remained stable (median 0.05 to 0.00 logMAR, P = 0.351), while the treatment interval was significantly extended (median 7.0 to 9.0 weeks, P < 0.001). Central retinal thickness and pigment epithelial detachment height decreased significantly (P = 0.035 and P = 0.021, respectively). The proportion of eyes with subretinal fluid significantly decreased from 74.3 to 37.1% (P = 0.003). Of the discontinuations, 4 were due to worsening exudation and 5 to inability to extend to ?8 weeks as required by labeling. No intraocular inflammation or serious adverse events occurred.
Conclusions Switching to aflibercept 8?mg achieved anatomical improvements and longer treatment intervals in ~80% of nAMD cases, suggesting it may be a useful alternative to aflibercept 2 mg. However, continuation may be difficult in refractory cases requiring frequent injections before switching. en-copyright= kn-copyright= en-aut-name=KindoHiroya en-aut-sei=Kindo en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HosokawaMio Morizane en-aut-sei=Hosokawa en-aut-mei=Mio Morizane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=HayashiJunko en-aut-sei=Hayashi en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Aflibercept 8 mg kn-keyword=Aflibercept 8 mg en-keyword=Neovascular age-related macular degeneration kn-keyword=Neovascular age-related macular degeneration en-keyword=Treat-and-extend kn-keyword=Treat-and-extend en-keyword=Switching kn-keyword=Switching en-keyword=Treatment interval kn-keyword=Treatment interval END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=6 article-no= start-page=oeaf162 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=Sex differences in the progression of cardiovascular?kidney?metabolic syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Cardiovascular?kidney?metabolic (CKM) syndrome is a novel disease concept; however, sex differences in its progression remain uncertain. This study aimed to quantify the risk of cardiovascular disease (CVD) events across CKM stages and to explore sex differences in this association.
Methods and results We included 1 332 436 individuals (581 423 males and 751 013 females) from the DeSC database between 2014 and 2023 who had no prior CVD (i.e. CKM Stage 4). CKM stages were categorized as follows: Stage 0 (no CKM risk factors); Stage 1 (excess or dysfunctional adiposity); Stage 2 [metabolic risk factors and chronic kidney diseases (CKD)], and Stage 3 (subclinical CVD). We used Cox models to examine the association of CKM stages with the risk of CVD events (newly developed CKM Stage 4), including myocardial infarction, stroke, heart failure, atrial fibrillation, and peripheral artery disease. The progression from CKM Stages 0 to 3 showed a dose-dependent increase in adjusted hazard ratios (HR) for developing CVD events, with the highest risk at Stage 3 [1.85 (95% CI: 1.80?1.90)]. A similar pattern was observed in both males and females. However, the magnitude of associations for CKM stages 1?3 differed between the sexes: HR by Stage 1, 1.12 (1.04?1.21) vs. 1.12 (1.07?1.16); by Stage 2, 1.78 (1.69?1.88) vs. 1.43 (1.39?1.48); by Stage 3, 1.99 (1.89?2.10) vs. 1.82 (1.76?1.88); and P-for-interaction values were 0.87, < 0.001, and 0.005, respectively.
Conclusion In this large nationwide cohort, CKM stage progression was associated with higher CVD risk in both sexes, with modest sex-specific differences. These findings highlight the value of CKM staging for early risk assessment, regardless of sex. en-copyright= kn-copyright= en-aut-name=TayaSatoshi en-aut-sei=Taya en-aut-mei=Satoshi kn-aut-name=

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=411 cd-vols= no-issue=1 article-no= start-page=22 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=The impact of liver transection depth on surgical difficulty in robotic versus laparoscopic limited liver resection (TAKUMI-5) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Although robotic liver resection (RLR) has gained popularity worldwide, limited liver resection remains the mainstay of RLR. This study aimed to investigate the effect of parameters, including liver transection depth (LTD), on surgical difficulty in limited RLR compared with limited laparoscopic liver resection (LLR).
Methods This retrospective study included 105 patients who underwent limited RLR (n?=?56) or LLR (n?=?49) at our institution between January 2018 and December 2024. After comparing outcomes of RLR and LLR, multivariate analyses were performed to examine effect of LTD on surgical difficulty (defined as prolonged operative time). Moreover, outcomes stratified by LTD cut-off values were compared between the groups.
Results Median LTD was similar between groups (RLR vs. LLR: 2.6 vs. 2.6 cm, P?=?0.77). LTD was significantly correlated with operative time for both procedures (RLR, R? = 0.07, P?=?0.042; LLR, R? = 0.08, P?=?0.046). Multivariate analyses demonstrated that LLR (odds ratio, 6.9; P??2.5 cm), the RLR group had significantly shorter operative time (145 vs. 231 min, P? Conclusion This study investigated impact of LTD on surgical outcomes in patients who underwent limited RLR compared to those who underwent limited LLR. LTD may be a useful parameter for estimating surgical difficulty in limited RLR. Moreover, robotic surgery may be favorable for deeper and limited liver resections. en-copyright= kn-copyright= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoAtene en-aut-sei=Ito en-aut-mei=Atene kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokoyamaShohei en-aut-sei=Yokoyama en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Laparoscopic surgery kn-keyword=Laparoscopic surgery en-keyword=Limited liver resection kn-keyword=Limited liver resection en-keyword=Textbook outcome kn-keyword=Textbook outcome END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=10 article-no= start-page=e70269 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=D3 lymph node dissection in colon cancer patients aged 90?years and over: Is it justified?

This study aimed to evaluate the impact of D3 LND on outcomes in this specific, vulnerable population.
Method: This retrospective cohort study evaluated 166 patients aged ?90?years with pathological Stages II?III colon cancer undergoing non-D3 or D3 LND from a multicentre database (2011?2022). Postoperative complications, overall survival and cancer-specific survival were compared between LND groups using propensity score-weighted analyses.
Results: D3 LND group had significantly more females and laparoscopic procedures. Operation time was longer, and blood loss was lower in the D3 LND group. Postoperative complications and severe complications were significantly fewer, and postoperative hospital stay was shorter in the D3 LND group. The number of harvested lymph nodes and distal margin was significantly higher in the D3 group. While unadjusted analysis showed better overall survival with D3 LND (p? Conclusion: In nonagenarian colon cancer patients, D3 LND is safe and feasible without increasing complications, but lacks survival benefit. Careful consideration is warranted, and high-quality D2 LND must be consistently ensured when limited surgery is chosen. en-copyright= kn-copyright= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakanagaSatoe en-aut-sei=Takanaga en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InadaRyo en-aut-sei=Inada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToshimaToshiaki en-aut-sei=Toshima en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtaniTsuyoshi en-aut-sei=Ohtani en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaRyosuke en-aut-sei=Yoshida en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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= en-aut-name=Setouchi Colorectal Neoplasm Registration study group collaborators en-aut-sei=Setouchi Colorectal Neoplasm Registration study group collaborators en-aut-mei= 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 Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Saiseikai Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil= kn-affil= en-keyword=colon cancer kn-keyword=colon cancer en-keyword=lymph node dissection kn-keyword=lymph node dissection en-keyword=nonagenarian kn-keyword=nonagenarian en-keyword=postoperative complication kn-keyword=postoperative complication en-keyword=survival benefit kn-keyword=survival benefit END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e85768 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Severe Anemia Caused by a Colorectal Lipoma With Central Erosions: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colorectal lipomas are benign tumors that are often asymptomatic and discovered incidentally. In most cases, they can be managed conservatively with observation. We report the case of a man in his 70s with a colorectal lipoma located in the cecum. An investigation into his severe anemia led to the suspicion that the cecal lipoma was the underlying cause. An ileocecal resection was performed. Erosions were observed at the center of the lipoma. Although small colorectal lipomas are generally asymptomatic and rarely cause anemia, periodic endoscopic examinations are recommended. These lesions should be considered in the differential diagnosis of lower gastrointestinal bleeding. en-copyright= kn-copyright= en-aut-name=YoshidaYusuke en-aut-sei=Yoshida en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeKo en-aut-sei=Watanabe en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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 Hospital kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=anemia kn-keyword=anemia en-keyword=bleeding lipoma kn-keyword=bleeding lipoma en-keyword=colorectal lipoma kn-keyword=colorectal lipoma en-keyword=laparoscopic surgery kn-keyword=laparoscopic surgery en-keyword=mucosal erosion kn-keyword=mucosal erosion END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high-throughput screening, together with an Escherichia coli library containing plasmid clones of all genes from strain W3110, to identify genes whose overexpression enhances virulence. We found that overexpression of the uncharacterized protein YaiX promoted bacterial proliferation in silkworms and increased host lethality. Compared with the empty-vector control, the YaiX-overexpressing strain exhibited resistance to multiple antimicrobial agents with diverse mechanisms of action, including β-lactams, tetracyclines, fluoroquinolones, aminoglycosides, cationic surfactants, and hydrogen peroxide. Sequence analysis revealed that amino acids 18?52 of YaiX contain a transferase hexapeptide domain predicted to form a left-handed parallel β-helix. Overexpression of YaiX mutants lacking regions outside this domain conferred ampicillin resistance, whereas deletion of the hexapeptide domain abolished this phenotype. RNA sequencing and GO enrichment analyses further indicated that YaiX overexpression altered the expression of genes encoding RNA-binding proteins and porins. These findings suggest that YaiX overexpression, through its hexapeptide domain, modulates gene expression and contributes to both multidrug resistance and enhanced virulence in E. coli. en-copyright= kn-copyright= en-aut-name=HonguKinuka en-aut-sei=Hongu en-aut-mei=Kinuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakiTomoki en-aut-sei=Kosaki en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiShin‐Ichi en-aut-sei=Miyoshi en-aut-mei=Shin‐Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Escherichia coli kn-keyword=Escherichia coli en-keyword=hexapeptide domain kn-keyword=hexapeptide domain en-keyword=multidrug resistance kn-keyword=multidrug resistance en-keyword=pseudogene function kn-keyword=pseudogene function en-keyword=RNA‐seq kn-keyword=RNA‐seq en-keyword=silkworm infection model kn-keyword=silkworm infection model en-keyword=virulence kn-keyword=virulence en-keyword=yaiX kn-keyword=yaiX END start-ver=1.4 cd-journal=joma no-vol=411 cd-vols= no-issue=1 article-no= start-page=21 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=Surgical outcomes and patient selection in nonagenarians with colon cancer: a comparative multi-institutional study of laparoscopic and open approaches en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The appropriate surgical approach for colon cancer (CC) in nonagenarian patients remains a subject of clinical debate. This study aimed to compare the short-term outcomes of laparoscopic (Lap) versus open (Open) surgery in patients aged???90 years with resectable colon cancer.
Methods This multi-institutional retrospective cohort study included oldest-old patientswith pathological Stage II/III CC who underwent elective surgery at 15 hospitals between 2011 and 2022. Patients with rectal cancer, Stage 0/I/IV disease, or emergency surgery were excluded. To address selection bias, inverse-probability-weighted regression adjustment and stabilized inverse probability of treatment weighting (sIPTW) were applied. The primary outcome was postoperative complications; secondary outcomes included overall survival (OS).
Results Median age was 92 years in both groups. Before adjustment, the Lap group had a higher proportion of female patients (p?=?0.038) and lower ASA scores (p?=?0.01). Laparoscopic surgery was associated with a significantly longer operative time (220 vs. 171 min, p?=?0.046) but less intraoperative blood loss (10 vs. 78 mL, p? Conclusion Both laparoscopic and open surgery are feasible options for selected nonagenarians with colon cancer. Laparoscopic surgery may offer benefits in terms of reduced blood loss and shorter hospitalization, despite longer operative times. Careful patient selection considering frailty and comorbidities is essential in determining the most appropriate surgical approach. en-copyright= kn-copyright= en-aut-name=ShojiRyohei en-aut-sei=Shoji

C-reactive protein as a predictive biomarker for postoperative complications following robot-assisted surgery for rectal cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=This retrospective cohort study aimed to assess the predictive value of early postoperative C-reactive protein (CRP) levels for complications following robot-assisted rectal surgery (RARS) for rectal cancer. We analyzed data from 117 consecutive patients who underwent elective RARS at Okayama University Hospital between September 2020 and January 2025. Serum CRP levels were routinely measured preoperatively and on postoperative days (POD) 1 and 4. The primary outcome was the occurrence of any postoperative complication within 30 days, classified according to the Clavien?Dindo grading system. Postoperative complications were observed in 26 patients, representing 22.2% of the cohort. Univariate analysis revealed that several factors were significantly associated with complications, including older age, higher ASA score, neoadjuvant therapy, stoma creation, prolonged operative time, and elevated CRP levels on POD1 and POD4. Notably, multivariate logistic regression analysis identified POD1 CRP as a robust independent predictor of overall postoperative complications (adjusted odds ratio 0.77, 95% confidence interval (CI) [0.63?0.93], p? 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=46 cd-vols= no-issue=1 article-no= start-page=e70089 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lifestyle Factors and Current Alcohol Consumption Among Japanese Adolescents During the COVID-19 Pandemic: A Nationwide Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The COVID-19 pandemic may have influenced drinking behaviors in minors by disrupting daily routines and increasing psychosocial stress, although alcohol use among Japanese adolescents has declined in recent years. We aimed to clarify the relationships between current alcohol consumption and lifestyle factors during the COVID-19 pandemic based on a nationwide cross-sectional survey.
Methods: This cross-sectional study analyzed data from the 2021 Lifestyle Survey of Adolescents, a nationwide survey conducted in Japan during the COVID-19 pandemic. A total of 15?549 junior and senior high school students (7645 boys and 7904 girls) were included. Current alcohol consumption was defined as drinking on at least 1?day in the past 30?days. Multivariable logistic regression analyses were used to examine associations between current alcohol consumption and lifestyle factors, including irregular sleep patterns, irregular dietary habits, and increased screen time. Sex-stratified analyses and interaction tests were also performed.
Results: The overall prevalence of current alcohol consumption was 2.1%, with slightly higher rates among boys (2.2%) than girls (2.0%). Current alcohol consumption was significantly associated with irregular sleep patterns (odds ratio [OR]?=?1.51; 95% confidence interval [CI], 1.17?1.95) and irregular dietary habits (OR?=?1.68; 95% CI, 1.18?2.40). An association with increased screen time was also observed (OR?=?1.29; 95% CI, 1.00?1.69), particularly among boys. A significant interaction by sex was detected for irregular sleep patterns (p for interaction?=?0.013).
Conclusions: Alcohol consumption among Japanese adolescents was associated with irregular sleep and dietary habits and, among boys, with increased screen time. These findings highlight the importance of promoting regular routines and addressing lifestyle-related risks to prevent current alcohol consumption among adolescents during public health crises.

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=27 cd-vols= no-issue=1 article-no= start-page=16 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=Compound heterozygosity of a novel missense variant and exonic deletion in hypomyelinating leukodystrophy 15 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypomyelinating leukodystrophy 15 (HLD15) results from biallelic pathogenic variants in EPRS1, but exonic deletions have not been reported. We describe a 40-year-old woman with mild intellectual disability, ataxia, dystonia, and MRI showing hypomyelination. Whole-exome sequencing identified a heterozygous missense variant in the prolyl-tRNA synthetase domain of EPRS1 (c.3430 C?>?G; p.Leu1144Val, NM_004446.3), without second variant. Whole-genome sequencing revealed a heterozygous 220-bp deletion spanning exon 15 (c.1743-30_1932del), and segregation analysis confirmed compound heterozygosity. RT-PCR from lymphoblastoid cells demonstrated exon-15 skipping leading to a frameshift (p.Asn582Serfs*10) and nonsense-mediated decay, leaving predominant expression of the paternally inherited missense allele. These findings support loss-of-function for the deletion and classify c.3430 C?>?G as likely pathogenic under ACMG/AMP criteria (PM1, PM2, PM3, PP3). This case represents the first exonic deletion reported in EPRS1. The relatively mild, adult-onset phenotype broadens both mutational and clinical spectra of HLD15 and highlights the importance of structural-variant anal 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=MatsukawaTakashi en-aut-sei=Matsukawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OrimoKenta en-aut-sei=Orimo en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UedaKunihiro en-aut-sei=Ueda en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SekiTomonari en-aut-sei=Seki en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiioYasushi en-aut-sei=Shiio en-aut-mei=Yasushi 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=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki 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=TsujiShoji en-aut-sei=Tsuji en-aut-mei=Shoji 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, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan Department of Neurology kn-affil= affil-num=2 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan Department of Neurology kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan Department of Neurology kn-affil= affil-num=4 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan Department of Neurology kn-affil= affil-num=5 en-affil=Department of Neurology, Tokyo Teishin Hospital kn-affil= affil-num=6 en-affil=Department of Neurology, Tokyo Teishin Hospital 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 Neurology, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Radiology, School of Medicine, Jichi Medical University, kn-affil= affil-num=10 en-affil=Institute of Medical Genomics, International University of Health and Welfare kn-affil= affil-num=11 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan Department of Neurology kn-affil= en-keyword=Hypomyelinating leukodystrophy kn-keyword=Hypomyelinating leukodystrophy en-keyword=EPRS1 kn-keyword=EPRS1 en-keyword=Structural variant kn-keyword=Structural variant en-keyword=Exon deletion kn-keyword=Exon deletion en-keyword=Nonsense?mediated decay kn-keyword=Nonsense?mediated decay en-keyword=Whole?genome sequencing kn-keyword=Whole?genome sequencing END start-ver=1.4 cd-journal=joma no-vol=414 cd-vols= no-issue= article-no= start-page=578885 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immuno-deficient features of thymoma-associated myasthenia gravis patients with hypogammaglobulinemia: A condition comparable to Good's syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Good's syndrome (GS) is a rare immunodeficiency disorder associated with thymoma, characterized by hypogammaglobulinemia and recurrent infections; however, its clinical significance in thymoma-associated myasthenia gravis (TAMG) remains unclear. We retrospectively reviewed 30 patients with TAMG admitted to our center between January 2010 and March 2022. We defined GS-like immunodeficiency as serum IgG below the institutional cutoff of 861 mg/dL and a history of two or more infections requiring antimicrobial treatment; 11 patients (36.7%) met this definition. Compared with the remaining patients, the GS-like group had higher incidences of malignancy (45.5% vs. 5.3%, p = 0.016) and autoimmune diseases other than MG (36.4% vs. 5.3%, p = 0.047), lower peripheral lymphocyte counts (median 1100/μL vs. 2200/μL, p = 0.0051), and more frequent airflow obstruction defined by one second to forced vital capacity ratio of less than 70% (60.0% vs. 5.3%, p = 0.0026). Five deaths occurred in the GS-like group, and none in the other; median survival from the first antimicrobial-treated infection was 5.0 years. These findings imply that TAMG patients with GS-like immunodeficiency have a worse prognosis, underscoring the need for close monitoring and timely adjustments of MG management.

Pancreatic stellate cells (PSCs) drive fibrosis by excessively secreting extracellular matrix proteins such as collagen I. Collagen I is thought to physically obstruct the delivery of macromolecules, such as albumin, antibodies, and nanomedicines. Apart from its structural role, collagen signals through dedicated cell surface receptors, such as the discoidin domain receptors (DDR) 1/2. However, whether and how collagen signaling contributes to fibrotic barrier generation remains uncharacterized. Here, a 3D culture model of PDAC fibrosis constructed from patient PSCs is used to assess the contribution of DDR1/2-mediated collagen signaling. DDR1/2 inhibition diminishes collagen I expression in PSCs to enhance macromolecular delivery. Moreover, MEK inhibitors exacerbate the fibrotic barrier by up-regulating collagen I, an effect reversed by inhibiting DDR1/2. Through isoform-specific targeting, inhibiting DDR1, but not DDR2, is shown to be effective. Downstream of DDR, the involvement of the PI3K/AKT/mTOR pathway is demonstrated, particularly alternative mTOR complexes involving MEAK7 and GIT1. Altogether, the results show in vitro that DDR1-mediated collagen signaling exacerbates the fibrotic barrier and may be targeted to enhance macromolecular drug delivery in PDAC. en-copyright=

idiopathic arthritis and those with rheumatoid arthritis in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Juvenile idiopathic arthritis (JIA) is a chronic inflammatory condition that frequently persists into adulthood, posing long-term challenges in disease control and quality of life. However, clinical management during the transitional and young adult phases remains insufficiently characterized, especially in comparison with adult-onset rheumatoid arthritis (RA). This study aimed to compare disease activity, medication use, and treatment practices between patients with oligoarticular/polyarticular JIA and those with RA, focusing on individuals aged 16?30 years.
Methods Data were derived from two nationwide multicenter databases in Japan?NinJa (National Database of Rheumatic Diseases in Japan) for RA and CoNinJa (a pediatric counterpart of NinJa) for JIA. A total of 176 JIA and 152 RA patients, all aged 16?30 years, were analyzed. Clinical parameters, disease activity indices, and medication profiles were compared using the Mann?Whitney U test and Fisher’s exact test.
Results Compared to RA patients, JIA patients demonstrated significantly lower disease activity (median SDAI 0.6 vs. 2.4) and higher remission rates, particularly Boolean remission (70% vs. 44%) (p? Conclusions Despite an overlap in age, patients with JIA and RA exhibit distinct disease characteristics and therapeutic patterns. These differences underscore the need to expand approved treatment options for JIA, promote equitable access to biologics, and strengthen transitional care frameworks. Further research is warranted to explore long-term outcomes, reproductive health considerations, and socioeconomic barriers that influence treatment continuity in young adults with childhood-onset arthritis. en-copyright= kn-copyright= en-aut-name=MoriSho en-aut-sei=Mori en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShabanaKosuke en-aut-sei=Shabana

kn-title=Safety and efficacy of Rez?m water vapour energy therapy in BPH patients receiving antithrombotic therapy: A Japanese single‐centre experience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: The objective of this study is to evaluate the safety and efficacy of Rez?m water vapour energy therapy (WAVE) in Japanese patients with benign prostatic hyperplasia (BPH) continuing antithrombotic therapy and to validate the Okayama University Modified Clavien-Dindo classification (OU-mCD) for perioperative hematuria.
Patients and Methods: We retrospectively analysed 80 consecutive patients who underwent WAVE from August 2023 to July 2024, including 37 (46.2%) continuing antithrombotic therapy perioperatively. Hematuria within 30?days was graded using conventional Clavien-Dindo classification and the OU-mCD, a novel classification focusing on intervention necessity. We assessed clinically significant hematuria (Grade ? Ib), catheter-free rate, prostate volume reduction and haemoglobin change.
Results: Clinically significant hematuria occurred in 21.6% (8/37) of patients continuing antithrombotic therapy versus 4.7% (2/43) without (p?=?0.038). All 10 Grade ? Ib cases occurred during hospitalization with the catheter in place and were managed conservatively with continuous bladder irrigation (median 1 day); none required transfusion or surgical reintervention. Only one patient required temporary drug discontinuation. Treatment efficacy did not differ by antithrombotic status: 86.2% achieved PVR? Conclusion: WAVE can be safely performed with continued antithrombotic therapy. Whereas Grade ?Ib hematuria occurred in 25% of antiplatelet/anticoagulant users (vs. 5% without), 75% had no significant bleeding, and all complications were managed conservatively without transfusion. The OU-mCD provides precise complication stratification. These findings suggest outpatient procedures may be feasible with appropriate patient selection. en-copyright= kn-copyright= en-aut-name=MoriwakeTakatoshi en-aut-sei=Moriwake en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakuHaruki en-aut-sei=Kaku en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuboiIchiro en-aut-sei=Tsuboi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshinagaKasumi en-aut-sei=Yoshinaga en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamanoiTomoaki en-aut-sei=Yamanoi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=11 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=12 ORCID= en-aut-name=KatayamaYasuhiro en-aut-sei=Katayama en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Urology, Okamura Isshindo Hospital kn-affil= affil-num=14 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=benign prostatic hyperplasia kn-keyword=benign prostatic hyperplasia en-keyword=hematuriaantithrombotic therapy kn-keyword=hematuriaantithrombotic therapy en-keyword=Japanese kn-keyword=Japanese en-keyword=OU-mCD kn-keyword=OU-mCD en-keyword=water vapour energy therapy kn-keyword=water vapour energy therapy END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=11 article-no= start-page=e2543107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trastuzumab Deruxtecan for ERBB2-Mutant Metastatic Non?Small Cell Lung Cancer With or Without Brain Metastases: A Secondary Analysis of Randomized Clinical Trials en-subtitle= kn-subtitle= en-abstract= kn-abstract=Importance Brain metastases reduce overall survival rates of patients with non?small cell lung cancer (NSCLC); patients with epidermal growth factor receptor 2 (ERBB2 [formerly HER2])?mutant NSCLC are more likely to have baseline brain metastases. Trastuzumab deruxtecan (T-DXd) is an approved ERBB2-directed treatment for previously treated unresectable or metastatic ERBB2-mutant NSCLC.
Objective To assess the clinical effectiveness and safety of T-DXd 5.4 mg/kg and 6.4 mg/kg doses in patients with previously treated ERBB2-mutant metastatic NSCLC with or without untreated or previously treated stable brain metastases.
Design, Setting, and Participants This post hoc secondary analysis pooled patients from the DESTINY-Lung01 (data cutoff date: December 3, 2021) and DESTINY-Lung02 (data cutoff date: December 23, 2022) clinical trials by T-DXd dose (5.4 mg/kg and 6.4 mg/kg). DESTINY-Lung01 was a multicenter, open-label, 2-cohort, nonrandomized phase 2 study, while DESTINY-Lung02 was a dose-blinded, multicenter, 2-cohort, randomized phase 2 study. Participants had a previously treated ERBB2-mutant metastatic NSCLC with or without untreated or previously treated stable brain metastases at baseline. All statistical analyses were performed from April 2023 to October 2024.
Intervention Patients received a T-DXd dose of either 5.4 mg/kg or 6.4 mg/kg intravenously every 3 weeks.
Main Outcome and Measure Systemic and intracranial effectiveness by blinded independent central review using RECIST (Response Evaluation Criteria in Solid Tumors) version 1.1, sites of progression, and safety.
Results This analysis included 102 patients in the T-DXd 5.4-mg/kg dose group (65 females [64%]; median [range] age, 57.5 [37.0-83.0] years and 59.5 [30.0-79.0] years in patients with and without brain metastases, respectively) and 141 patients in the T-DXd 6.4-mg/kg dose group (94 females [67%]; median [range] age, 62.5 [29.0-88.0] years and 59.0 [27.0-83.0] years in patients with and without brain metastases, respectively). In each group, 31% (32 of 102) and 38% (54 of 141) of patients, respectively, had baseline brain metastases and 53% (17 of 32) and 44% (24 of 54), respectively, received prior brain metastasis treatment. In patients with and without brain metastases, systemic confirmed objective response rates (ORRs) were 47% (15 of 32; 95% CI, 29%-65%) and 50% (35 of 70; 95% CI, 38%-62%), respectively, with the T-DXd 5.4-mg/kg dose, and 50% (27 of 54; 95% CI, 36%-64%) and 59% (51 of 87; 95% CI, 48%-69%) with the T-DXd 6.4-mg/kg dose. Median progression-free survival was 7.1 (95% CI, 5.5-9.7) months in the T-DXd 5.4-mg/kg dose group and 7.1 (95% CI, 4.5-9.6) months in the T-DXd 6.4-mg/kg dose group of patients with baseline brain metastases. Among patients with measurable baseline brain metastases, intracranial confirmed ORRs were 50% (7 of 14; 95% CI, 23%-77%) with the T-DXd 5.4-mg/kg dose and 30% (9 of 30; 95% CI, 15%-49%) with the T-DXd 6.4-mg/kg dose. At both doses, the safety profile of T-DXd was generally manageable, regardless of baseline brain metastases, favoring the T-DXd 5.4 mg/kg dose.
Conclusions and Relevance In this secondary analysis, T-DXd at the approved dose of 5.4 mg/kg showed antitumor activity in patients with previously treated ERBB2-mutant metastatic NSCLC with or without brain metastases. This finding supports T-DXd 5.4 mg/kg use in this population. en-copyright= kn-copyright= 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=

HER2-Mutant Metastatic NSCLC en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Trastuzumab deruxtecan (T-DXd) demonstrated strong and durable responses in patients with previously treated HER2 (ERBB2) mutant (HER2m) metastatic NSCLC (mNSCLC) in the DESTINY-Lung02 primary analysis (December 23, 2022, data cutoff). This final analysis evaluated T-DXd efficacy and safety after 8 additional months of follow-up, including clinically relevant subgroups and patient-reported outcomes.
Methods: DESTINY-Lung02 was a randomized, dose-blinded, multicenter, phase 2 trial. Patients with previously treated HER2m mNSCLC were randomized 2:1 to receive T-DXd 5.4 or 6.4 mg/kg once every 3 weeks. Primary end point was confirmed objective response rate by blinded independent central review.
Results: As of August 25, 2023, 102 and 50 patients had received T-DXd 5.4 or 6.4 mg/kg, respectively. Median follow-up (Q1?Q3) was 15.8 (8.2?20.7) months and 16.5 (9.4?20.8) months, respectively. Confirmed objective response rate (95% confidence interval) was 50.0% (51/102; 39.9%?60.1%) and 56.0% (28/50; 41.3%?70.0%), respectively. Safety profile was acceptable and generally manageable. Accordingly, median treatment duration (Q1?Q3) was 7.7 (3.7?14.4) months and 8.3 (2.8?13.1) months; drug-related grade 3 or higher treatment-emergent adverse events occurred in 39.6% (40/101) and 60.0% (30/50), with nausea most common (67.3% [68/101], 82.0% [41/50]). Adjudicated drug-related interstitial lung disease occurred in 14.9% (15/101) and 32.0% (16/50), mostly grade 1 or 2 with one grade 5 in each arm. Health-related quality of life was preserved for the duration of T-DXd treatment while sample size was sufficient for analysis, with no adverse effects on health-related quality of life observed at either dose.
Conclusions: T-DXd demonstrated strong and durable responses at both doses, with no clinically significant changes in toxicity. The approved 5.4-mg/kg dose demonstrated a more favorable benefit-risk profile, including lower adjudicated drug-related interstitial lung disease incidence.

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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical and Genetic Landscape of Glioblastoma, IDH-Wildtype With FGFR Gene Family Alterations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioblastoma, isocitrate dehydrogenase wildtype (GBM, IDH-wt), is a highly aggressive brain tumor with a poor prognosis. Alterations in the fibroblast growth factor receptor (FGFR) gene family?such as FGFR::TACC fusions and FGFR1 mutations?have emerged as potential therapeutic targets; however, their clinical and genetic features in GBM, IDH-wt remain unclear. We analyzed 1076 GBM, IDH-wt cases using comprehensive genomic profiling data from the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database in Japan. FGFR alterations were detected in 8.0% of patients, including FGFR::TACC fusions (3.3%) and FGFR1 mutations (2.9%). The FGFR::TACC fusion-positive group was older at diagnosis and showed higher frequencies of TERT promoter mutation and MDM2 amplification, and lower frequencies of EGFR amplification and TP53 mutation, compared with the fusion-negative group. The FGFR1 mutation-positive group was enriched for ATRX, NF1, and PIK3CA mutations and had significantly fewer TERT promoter and PTEN mutations, compared with the mutation-negative group. No significant differences in overall survival were observed, although both groups tended to have longer median overall survival compared with their respective negative groups. This study represents the largest genomic cohort to date of FGFR alterations in GBM, IDH-wt. FGFR::TACC fusion-positive and FGFR1 mutation-positive GBMs exhibited distinct genetic profiles, highlighting the clinical relevance of molecular subclassification and providing insight for future therapeutic strategies. en-copyright= kn-copyright= en-aut-name=KegoyaYasuhito en-aut-sei=Kegoya en-aut-mei=Yasuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

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

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

kn-abstract=Some anaplastic lymphoma kinase (ALK) gene rearrangement?positive lung cancers show early resistance, within 3 months, to alectinib. This study investigated the clinical and molecular characteristics of these patients. We analyzed patients with unresectable stage III/IV disease without indications for radical radiotherapy and recurrent ALK-positive lung cancer who received alectinib as the primary ALK tyrosine kinase inhibitor between 2013 and 2021 at nine hospitals. In total, 103 patients were included. The median age was 65 years; 44 were male and 22 had brain metastases. The median progression-free survival and overall survival (OS) were 28.7 and 80.6 months. Nineteen patients treated for ?3 months and 84 treated for >3 months were categorized into the early resistance and responder groups, respectively. The early resistance group had significantly shorter OS (8.4 months vs. not estimable, P < 0.001) and was significantly more likely to have brain metastases (42% vs. 17%, P = 0.027). They also showed elevated inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR). Univariate analysis identified brain metastases and high NLR as significant predictors of early resistance. Spatial transcriptome analysis and immunohistochemical staining revealed upregulation of annexin A1 (ANXA1), a calcium-dependent phospholipid-binding protein involved in inflammation and cancer progression, in the early resistance group. Interleukin 6 stimulation, prompted by elevated inflammatory markers, increased ANXA1 expression and reduced alectinib sensitivity. Knockdown of ANXA1 improved alectinib sensitivity in alectinib-resistant cells. In conclusion, brain metastases and high NLR are associated with early resistance. ANXA1 may play an important role in mediating early resistance. New treatment options for the early resistance group are required. en-copyright= kn-copyright= en-aut-name=KuribayashiTadahiro en-aut-sei=Kuribayashi en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokoyamaToshihide en-aut-sei=Yokoyama en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuyamaShoichi en-aut-sei=Kuyama en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoYuka en-aut-sei=Kato en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KudoKenichiro en-aut-sei=Kudo en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HoritaNaokatsu en-aut-sei=Horita en-aut-mei=Naokatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KayataniHiroe en-aut-sei=Kayatani en-aut-mei=Hiroe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=InoueMasaaki en-aut-sei=Inoue en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SugimotoKeisuke en-aut-sei=Sugimoto en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Respiratory Medicine, Ohara Healthcare Foundation, Kurashiki Central Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, NHO Iwakuni Clinical Center kn-affil= affil-num=8 en-affil=Department of Thoracic Oncology and Medicine, National Hospital Organization, Shikoku Cancer Center kn-affil= affil-num=9 en-affil=Department of Respiratory Medicine, National Hospital Organization Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Kure Kyosai Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=12 en-affil=Department of Chest Surgery, Shimonoseki City Hospital kn-affil= affil-num=13 en-affil=Department of Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= affil-num=14 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=16 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=17 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=sr.2024-0099 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Qualification Examination for Specialists and Instructors in the Japanese Society of Neuroendovascular Therapy: History and Current Status en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neuroendovascular therapy is a key treatment for cerebrovascular disorders, driven by advancements in devices and techniques. The Japanese Society for Neuroendovascular Therapy (JSNET) established a certification system in 1997 to ensure operator competence and minimize complications, with the first examination in 2002. JSNET offers 2 main certifications: specialist and instructor. Specialists perform basic procedures, while instructors lead in practice, education, and research. In 2020, the mechanical thrombectomy practitioner qualification was added to promote mechanical thrombectomy. Applicants must have a JSNET membership, relevant certifications, training, and documented experience. The certification process includes rigorous written and practical examinations that now employ non-fluoroscopic models. Certification renewal every 5 years requires conference participation and a continuing education program. Public awareness and integration into stroke center designations have grown. Over 2200 specialists, including more than 500 instructors, have been certified, significantly advancing neuroendovascular therapy in Japan. JSNET aims to continue improving certification and education to maintain high standards. en-copyright= kn-copyright= en-aut-name=YoshimuraShinichi en-aut-sei=Yoshimura en-aut-mei=Shinichi kn-aut-name=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distinct associations of blood pressure phenotypes with subclinical cerebrovascular disease and coronary artery calcification in Japanese men en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypertension, encompassing white-coat hypertension (WCH), masked hypertension (MH), and sustained hypertension (SH), is an established risk factor for cardiovascular diseases (CVDs), including atherosclerosis. However, among the general population, findings on which target organ is affected by the different phenotypes of hypertension remain unclear. In this community-based observational study of Shiga Epidemiological Study of Subclinical Atherosclerosis, 740 Japanese men underwent brain magnetic resonance imaging to assess the presence of lacunar infarction, white-matter hyperintensities, microbleeds, and intracranial artery stenosis (ICAS) between 2012 and 2015. They also underwent office blood pressure (BP) measurements, home BP monitoring for at least five consecutive days, and coronary artery calcification (CAC) assessments between 2010 and 2014. The final analysis included 686 participants without a history of CVDs. Of the 686 participants, the mean age (?±?SD) was 68.0 (?±?8.3) years, and 39.3% were taking antihypertensive medication. In multivariable-adjusted models, each of WCH, MH, and SH was significantly associated with a higher risk of microbleeds compared to normotension. However, the association of WCH with microbleeds was evident only among those on antihypertensive medication (adjusted odds ratio [OR] 6.75 [95% CI 1.83?24.86]) and absent in those not on such medication (adjusted OR 1.20 [95% CI 0.31?4.73]). SH was associated with lacunar infarction, ICAS, and CAC. Among Japanese men, WCH, MH, SH were associated with subclinical cerebrovascular diseases, whereas only SH was associated with CAC. Moreover, any elevated BP phenotype increased the risk of microbleeds. Our findings suggest that different hypertension phenotypes distinctly affect target organs, particularly the brain and heart. en-copyright= kn-copyright= en-aut-name=BayaraaNomin en-aut-sei=Bayaraa en-aut-mei=Nomin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoYuichiro en-aut-sei=Yano en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadotaAya en-aut-sei=Kadota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AzaharNazar Mohd en-aut-sei=Azahar en-aut-mei=Nazar Mohd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PhapTran Ngoc Hoang en-aut-sei=Phap en-aut-mei=Tran Ngoc Hoang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoKeiko en-aut-sei=Kondo en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToriiSayuki en-aut-sei=Torii en-aut-mei=Sayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiyoshiAkira en-aut-sei=Fujiyoshi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhkuboTakayoshi en-aut-sei=Ohkubo en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShiinoAkihiko en-aut-sei=Shiino en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NozakiKazuhiko en-aut-sei=Nozaki en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=2 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=3 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil=National Institutes of Biomedical Innovation, Health and Nutrition kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=8 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=9 en-affil=Department of Hygiene, School of Medicine, Wakayama Medical University kn-affil= affil-num=10 en-affil=Department of Hygiene and Public Health, Teikyo University School of Medicine kn-affil= affil-num=11 en-affil=Molecular Neuroscience Research Center, Shiga University of Medical Science kn-affil= affil-num=12 en-affil=Department of Neurosurgery, Shiga University of Medical Science kn-affil= affil-num=13 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= en-keyword=Blood pressure phenotypes kn-keyword=Blood pressure phenotypes en-keyword=Morning hypertension kn-keyword=Morning hypertension en-keyword=Home blood pressure kn-keyword=Home blood pressure en-keyword=Subclinical cerebrovascular disease kn-keyword=Subclinical cerebrovascular disease en-keyword=Coronary artery calcification kn-keyword=Coronary artery calcification END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=25-00095 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Examining OpenFOAM-based LES analysis in terms of inviscid energy conservation and viscous turbulence decay en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study examines an OpenFOAM-based LES analysis from the viewpoints of inviscid energy conservation and viscous turbulence decay. The Smagorinsky model is employed as the sub-grid scale (SGS) model, and a two-dimensional periodic analytical solution and a three-dimensional periodic Taylor-Green vortex (TGV) are employed to represent inviscid flows. The analytical relationship for the kinetic energy K, dK/dt = 0, with t as the dimensionless time, is utilized to validate the OpenFOAM results. For the viscous flow case, the TGV flow in a three-dimensional periodic cubic domain is adopted, and its turbulence kinetic energy distribution is compared with that obtained by a spectral method to examine the analysis. The OpenFOAM-based analysis exhibits energy conservation error in flows that should ideally conserve energy. For the two-dimensional flow, this error decreases with increasing grid resolution N. However, in the three-dimensional flow, the error does not improve even with higher N. In the three-dimensional TGV flow, the turbulence kinetic energy predicted by OpenFOAM exhibits a strong agreement with that from the spectral method when a standard constant value of the Smagorinsky model is employed and the mesh is sufficiently refined. Conversely, for a condition of relatively coarse mesh, the decay characteristics of turbulent kinetic energy deviate from those of the spectral method, and a higher constant value of the Smagorinsky model than the default value becomes necessary to reproduce comparable results. These results suggests that even in LES simulations where highly accurate conservation laws are not satisfied, adjusting the model constants so that the predicted values match experimental or numerical reference data can improve the apparent reliability of the turbulent kinetic energy in the decaying turbulence. en-copyright= kn-copyright= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Numerical simulation kn-keyword=Numerical simulation en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Energy conservation kn-keyword=Energy conservation en-keyword=Decaying turbulence kn-keyword=Decaying turbulence END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=3 article-no= start-page=179 end-page=187 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and applications of porous carbonaceous materials with inherited molecular structural features from the precursor molecules en-subtitle= kn-subtitle= en-abstract= kn-abstract=The carbonization of organic crystalline materials, such as metal organic frameworks and covalent organic frameworks, has emerged as a promising approach for producing functional porous carbonaceous materials. However, both the chemically defined long-term ordered structures and the local chemical structures derived from these precursor materials are generally lost, resulting in amorphous carbons. As a result, controlling the molecular-level structure of nanoporous carbons remains a significant challenge. We report a new bottom-up synthesis approach for porous carbons with a molecular-level design, involving the carbonization of well-designed precursor molecules by thermal polymerization. Among the resulting carbons, ordered carbonaceous frameworks, which contain a high-density of regularly aligned single-atomic metal species, have been identified as promising platforms for single-atom catalysts. This approach also enables the synthesis of various three-dimensional porous carbons that reflect the structural features of their precursor molecules. Recent progress in the synthesis and applications of porous carbons derived from molecular precursors is summarized, highlighting their potential for the development of functional materials. en-copyright= kn-copyright= en-aut-name=ChidaKoki en-aut-sei=Chida en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiTakeharu en-aut-sei=Yoshi en-aut-mei=Takeharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamiyaKazuhide en-aut-sei=Kamiya en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoRyota en-aut-sei=Sakamoto en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgoshiTomoki en-aut-sei=Ogoshi en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishiharaHirotomo en-aut-sei=Nishihara en-aut-mei=Hirotomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= affil-num=2 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Center for Solar Energy Chemistry, Graduate School of Engineering Science, The University of Osaka kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Tohoku University kn-affil= affil-num=6 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=7 en-affil=Department of Synthetic Chemistry and Biological Chemistry, Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= en-keyword=Ordered carbonaceous frameworks (OCFs) kn-keyword=Ordered carbonaceous frameworks (OCFs) en-keyword=Porous carbon materials kn-keyword=Porous carbon materials en-keyword=Single-atom catalysts (SACs) kn-keyword=Single-atom catalysts (SACs) en-keyword=Catalyst supports kn-keyword=Catalyst supports END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue= article-no= start-page=100540 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=Flow diverter treatment for internal carotid artery aneurysm following management of distal cerebral aneurysms: Technical note en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In recent years, the effectiveness of flow diverters (FDs) for the treatment of intracranial aneurysms has been reported. While FDs are effective, their deployment involves advancing a delivery wire distally, which may pose a risk if a distal aneurysm exists within the same artery. In such cases, the delivery wire could potentially perforate the distal aneurysm. Here, we present two cases of tandem aneurysms in which an internal carotid artery (ICA) aneurysm was treated with an FD following the treatment of a distal cerebral aneurysm.
Case description: A 44-year-old woman and a 67-year-old woman underwent magnetic resonance imaging for headache or abducens nerve palsy. In both cases, two aneurysms were revealed: one at the ICA and the other either at the middle cerebral artery or the top of the ICA. Due to the risk of perforation by the delivery wire during FD deployment, the distal aneurysms were treated first?either with surgical neck clipping or stent-assisted coil embolization. One month after the initial treatment, FD placement for the ICA aneurysm was performed as planned without complications in either case.
Discussion: This is the first report where tandem aneurysms were successfully treated with treatment for distal cerebral aneurysms, followed by FDs for proximal ICA aneurysms. We emphasize the potential risk of perforation of the distal aneurysm by the delivery wire during FD placement.
Conclusion: Treatment of distal cerebral aneurysms beforehand can help ensure the safe and effective use of FDs in patients with tandem aneurysms. en-copyright= kn-copyright= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=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=SotomeYuta en-aut-sei=Sotome en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=EbisudaniYuki en-aut-sei=Ebisudani en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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 Neurosurgery, Kawasaki Medical School kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Flow diverter kn-keyword=Flow diverter en-keyword=Tandem aneurysms kn-keyword=Tandem aneurysms en-keyword=Complication kn-keyword=Complication en-keyword=Perforation kn-keyword=Perforation en-keyword=Delivery wire kn-keyword=Delivery wire END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=6 article-no= start-page=410 end-page=412 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Transbrachial artery approach with an ultra-long sheath in intraoperative angiography for craniocervical junction arteriovenous fistula kn-title=頭蓋頚椎移行部動静脈瘻の開頭手術時における上腕動脈穿刺による脳血管撮影の有用性 en-subtitle= kn-subtitle= en-abstract=In surgery for craniocervical junction-arteriovenous fistula (CCJ-AVF), intraoperative angiography is often required to identify the abnormal vessels. However, conventional intraoperative angiography poses challenges related to sheath fixation and catheter manipulation. In this study, we present a novel method for intraoperative angiography for CCJ-AVF using an ultra-long sheath inserted via the brachial artery and positioned at the subclavian artery to perform vertebral artery angiography (VAG). We evaluated patient demographics and complications in cases where this angiography method was employed. VAG was successfully performed in all four intended cases, and no complications were observed. This method enables us to change patient positions easily and provides a clear visualization of the puncture site. The catheter is also simply manipulated, allowing us to perform VAG with ease. Furthermore, there is no concern about the interference between the C-arm and the surgical field. This angiography method appears to be effective. kn-abstract=頭蓋頚椎移行部動静脈瘻の手術では，異常血管の確認のため術中血管撮影が重要であるが，体位変換時のsheathの固定や撮影血管へのカテーテルの誘導が困難である．今回，頭蓋頚椎移行部動静脈瘻の開頭手術において上腕動脈穿刺によりultra-long

(GI-1Pta6605) has been identified as a pathogenicity island required for virulence because the deletion almost completely eliminated disease symptoms in inoculation tests at 4?×?105 CFU/ml. GI-1Pta6605 contains four cargo regions (CRs) named CR-1 to CR-4. The ?CR-4 mutant did not produce tabtoxin like ?GI-1 and disease symptoms did not develop in tobacco. However, it grew, although to a lesser extent than the wild-type strain. These results indicate that the tabtoxin biosynthetic gene cluster in GI-1 is required for virulence but not for establishment of compatibility. en-copyright= kn-copyright= en-aut-name=KunishiKotomi en-aut-sei=Kunishi en-aut-mei=Kotomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujisawaNorika en-aut-sei=Fujisawa en-aut-mei=Norika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 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=5 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=GI-1Pta6605 kn-keyword=GI-1Pta6605 en-keyword=Pathogenicity island kn-keyword=Pathogenicity island en-keyword=Pseudomonas syringae kn-keyword=Pseudomonas syringae en-keyword=Tabtoxin kn-keyword=Tabtoxin END start-ver=1.4 cd-journal=joma no-vol=183 cd-vols= no-issue= article-no= start-page=111902 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Monitoring postharvest water loss in eggplants (Solanum melongena L.) using UV-induced fluorescence imaging and multivariate analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eggplant (Solanum melongena L.) is susceptible to significant postharvest losses primarily due to water loss during storage, which affects market quality by causing texture and glossiness degradation. We investigated whether UV-induced fluorescence imaging and EEM (Excitation-Emission Matrix) fluorescence spectroscopy can non-destructively monitor WL under four storage regimes (10 °C/95 % RH, 20 °C/95 % RH, 20 °C/75 % RH, 10 °C/75 % RH). EEMs exhibited three regions; a 365/420 nm blue emission increased most under warm, low-humidity storage and is consistent with phenolic/lignin-related fluorescence. Side-view fluorescence (FL) images showed progressive blue-white emission and surface textural changes that tracked gravimetric water loss (WL). A PLSR model using combined color and texture features from FL and reflectance (CL) images achieved R2CV = 0.88 (RMSECV = 3.47 %) with only six features. To test a minimal predictor, we fit an Analysis of Covariance (ANCOVA) using Day-1 FL MeanBlue as a covariate and storage category as a factor with Leave One Out Cross-validation (LOOCV); this forecasted cumulative WL with R2LOOCV = 0.92 and MAE = 1.88 %. Importantly, this ANCOVA model using Day-1 blue-band fluorescence as a covariate was predictive only under 20 °C/75 % RH; under the other conditions, its contribution was weak. Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) models achieved accuracies of 94.4 % and 85.2 %, respectively, in differentiating storage conditions. These results support low-cost FL imaging as a practical tool to monitor WL and storage stress. en-copyright= kn-copyright= en-aut-name=RotichVincent en-aut-sei=Rotich en-aut-mei=Vincent kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GaoTianqi en-aut-sei=Gao en-aut-mei=Tianqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PrempreePanintorn en-aut-sei=Prempree en-aut-mei=Panintorn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayashiTakahiro en-aut-sei=Hayashi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NambaKazuhiko en-aut-sei=Namba en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MontaMitsuji en-aut-sei=Monta en-aut-mei=Mitsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishimotoMotomi en-aut-sei=Nishimoto en-aut-mei=Motomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoNaoshi en-aut-sei=Kondo en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=3 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto 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=Technology and Innovation Center, Daikin Industries, Ltd. kn-affil= affil-num=8 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=Eggplant kn-keyword=Eggplant en-keyword=Fluorescence spectroscopy kn-keyword=Fluorescence spectroscopy en-keyword=UV-Induced imaging kn-keyword=UV-Induced imaging en-keyword=Water loss kn-keyword=Water loss en-keyword=Postharvest quality kn-keyword=Postharvest quality en-keyword=Non-destructive assessment kn-keyword=Non-destructive assessment END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=16 article-no= start-page=9663 end-page=9677 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251011 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of sulfation for cellulose pulp to change its fiber morphology and appearance to transparent in water en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellulose pulp (CP) is composed mainly of cellulose which is one of the most useful and sustainable natural polymers. Cellulose-based materials, such as completely dispersed nanofibers and water-soluble cellulose, are transparent in water. Additionally, chemical modification of CP has been employed as a pretreatment for the preparation of nanofibers and to impart absorption properties derived from anionic functional groups. However, little is known about chemically modified CPs comprising micron-scale fibers that are transparent in water.In this study, we synthesized transparent sulfated cellulose pulp (TSCP) that exhibits good dispersion stability, high transparency in water, and highly swollen fiber structures. The sulfation method involved heating sulfamic acid and urea supported on CP. TSCP synthesized using a sulfamic acid amount relative to CP (Q) of 18.5, a molar ratio of urea to sulfamic acid (R) of 0.80, and a reaction temperature of 140 °C exhibited the highest total light transmittance (94.7%) in water, a degree of polymerization (535), and amount of sulfate groups (1.73 mmol/g). Polarization microscopy confirmed that most TSCP fibers swelled in water along the fiber width direction. The structure of hydrous-state TSCP was further confirmed using low-vacuum scanning electron microscopy. The maximum fiber width of the swollen TSCP reached 122 μm, which was approximately six times than that of CP. The crystallinity was equivalent to that of the original CP with a Cellulose I-type crystalline structure. This transparent, hydrous-state TSCP, comprising predominantly swollen CP fibers, demonstrates potential for applications as a transparent material. en-copyright= kn-copyright= en-aut-name=NishimuraAyato en-aut-sei=Nishimura en-aut-mei=Ayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaTetsuya en-aut-sei=Uchida en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Cellulose pulp kn-keyword=Cellulose pulp en-keyword=Sulfation kn-keyword=Sulfation en-keyword=Transparent kn-keyword=Transparent en-keyword=Swollen fiber structure kn-keyword=Swollen fiber structure en-keyword=Microscopy kn-keyword=Microscopy en-keyword=Refractive index kn-keyword=Refractive index END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=pgaf393 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chloroplast heat shock protein cpHsc70-1 interacts with thylakoid membrane remodeling protein VIPP1 C-terminal tail and controls VIPP1 oligomer assembly en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oxygenic photosynthetic organisms depend on the thylakoid membranes (TMs) for light-driven energy conversion. Recent studies on TM homeostasis (thylakostasis) have highlighted the essential role of the TM remodeling protein vesicle-inducing protein in plastid 1 (VIPP1). As a member of the endosomal sorting complexes required for transport-III (ESCRT-III)/phage shock protein A (PspA)/VIPP1 superfamily, VIPP1 forms large ring- and filament-like homo-oligomeric structures that exhibit a membrane remodeling activity. The oligomerization status was proposed to be modulated by the intrinsically disordered C-terminal tail (Vc), whereas its functional role remained unclear. Notably, this Vc region is conserved not only in photosynthetic VIPP1 but also in the PspA proteins of extremophilic species, implicating its role in membrane stress responses. To investigate the role of the Vc region in VIPP1 assembly, we performed coimmunoprecipitation assays in Arabidopsis chloroplasts and identified chloroplast-localized HSP70 proteins (cpHsc70) as major interactors. Among the two isoforms, cpHsc70-1 was found to be specifically required for modulating VIPP1 oligomeric assembly and dynamics in response to heat stress. Genetic analyses revealed that cpHsc70-1 facilitates the disassembly of VIPP1 oligomers, similarly to Vps4 ATPase in ESCRT-III; loss of either the Vc region or cpHsc70-1-impaired VIPP1 disassembly, resulting in more static oligomeric structures. Furthermore, cpHsc70-1 exhibited a broader role in chloroplast proteostasis, as the cphsc70-1 mutant showed impaired accumulation of green fluorescent protein (GFP)-fusion proteins. Together, our findings uncover a crucial crosstalk between proteostasis and thylakostasis in chloroplasts, coordinated by cpHsc70-1 and VIPP1 in response to membrane stress. en-copyright= kn-copyright= en-aut-name=LiDi en-aut-sei=Li en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GachieSarah Wanjiru en-aut-sei=Gachie en-aut-mei=Sarah Wanjiru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzawaShin-ichiro en-aut-sei=Ozawa en-aut-mei=Shin-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ScholzMartin en-aut-sei=Scholz en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HipplerMichael en-aut-sei=Hippler en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=chloroplast kn-keyword=chloroplast en-keyword=heat shock protein kn-keyword=heat shock protein en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=thylakoid membrane remodeling kn-keyword=thylakoid membrane remodeling END start-ver=1.4 cd-journal=joma no-vol=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=29 cd-vols= no-issue=1 article-no= start-page=146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safety and feasibility of D3 lymph node dissection in oldest-old patients undergoing colorectal cancer surgery: a multi-institutional, retrospective analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Colorectal cancer (CRC) is a significant health burden, with lymph node dissection (LND) playing a critical role in staging and guiding treatment. However, the optimal extent of LND for the oldest-old population (aged???90 years) remains undefined because of insufficient targeted clinical data. This study aimed to compare the short-term outcomes of D3 versus non-D3 LND in Stage II?III CRC in oldest-old patients.
Methods This retrospective cohort study utilized data from the Setouchi Colorectal Neoplasm Registration database, including 282 oldest-old patients with CRC treated between 2011 and 2022. Patients were stratified into D3 and non-D3 LND groups, with inverse-probability-weighted regression adjustment implemented to address potential confounding factors. Postoperative complications and hospital stays were analyzed using regression models and descriptive statistics.
Results D3 LND resulted in significantly higher lymph node harvests in both Stage II and Stage III patients (p? Conclusions D3 LND can be safely performed in oldest-old patients with CRC without increasing postoperative complications or extending hospital stays. These findings support the feasibility of extensive LND in this age gr en-copyright= kn-copyright= en-aut-name=InadaR. en-aut-sei=Inada en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei=

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=3 article-no= start-page=e105012 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Rare Association of Congenital Glaucoma and Retinitis Pigmentosa: A 22-Year Follow-Up Case en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary congenital glaucoma is a rare congenital disease with a genetic background that shows high intraocular pressure due to ocular outflow anomalies. Retinitis pigmentosa is a predominant form of inherited retinal disorders. In this study, we present the case of a patient with primary congenital glaucoma in association with retinitis pigmentosa. A four-month-old female baby was brought to the emergency department due to corneal opacity in the left eye. The intraocular pressure measured by a hand-held applanation tonometer was 40 mmHg in the right eye and 36 mmHg in the left eye. She was otherwise healthy and diagnosed with primary congenital glaucoma. She immediately underwent trabeculotomy ab externo in both eyes under general anesthesia, and the intraocular pressure was lowered to 15 mmHg in the right eye and 12 mmHg in the left eye three weeks later. At the age of nine months, she was found to have retinal degeneration along the upper and lower vascular arcades of the fundus in both eyes and was diagnosed with retinitis pigmentosa. At the age of one year and 10 months, the visual acuity was measured at 0.2 in the right eye and 0.2 in the left eye for the first time by a preferential looking procedure. The intraocular pressure was 9 mmHg in both eyes under sedation, and she did not use any topical medication. At the age of three years and three months, the uncorrected visual acuity and best-corrected visual acuity with myopic astigmatism correction were 0.1 and 0.15, respectively, in the right eye and 0.6 and 0.7, respectively, in the left eye. Occlusion therapy with an eye patch over the left eye for one hour daily was started. At the age of four years and 10 months, the best-corrected visual acuity was 0.7 in both eyes. At the age of six years, occlusion therapy was discontinued, and full-correction glasses were prescribed, based on cycloplegic refraction. The visual acuity in the right eye decreased to 0.3 at the age of 11 years and further to 0.1 at the age of 12 years, while the visual acuity in the left eye remained 0.8. Afterwards, she maintained a visual acuity of 0.1 in the right eye and 0.8 in the left eye until the age of 22 years. An incidental presence of primary congenital glaucoma in this patient led to the detection of retinitis pigmentosa in earlier years and allowed long-term follow-up for 22 years. Even though genetic testing was not performed for this patient, the abnormal function of primary cilia, designated as ciliopathy, might explain the co-occurrence of primary congenital glaucoma and retinitis pigmentosa. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=ciliopathy kn-keyword=ciliopathy en-keyword=cycloplegic refraction kn-keyword=cycloplegic refraction en-keyword=full-correction glasses kn-keyword=full-correction glasses en-keyword=goldmann perimetry kn-keyword=goldmann perimetry en-keyword=occlusion therapy kn-keyword=occlusion therapy en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=photoreceptor ellipsoid zone kn-keyword=photoreceptor ellipsoid zone en-keyword=primary congenital glaucoma kn-keyword=primary congenital glaucoma en-keyword=retinitis pigmentosa kn-keyword=retinitis pigmentosa en-keyword=trabeculotomy kn-keyword=trabeculotomy END start-ver=1.4 cd-journal=joma no-vol=94 cd-vols= no-issue=4 article-no= start-page=522 end-page=529 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Intermittent Low-temperature Storage Duration and Cycle on the Bolting and Flowering of Delphinium elatum in Summer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Early-bolting in summer is a major problem when growing delphinium seedlings in summer to produce cut flowers that will be shipped in autumn and winter. In this study, an intermittent low-temperature storage (ILTS) treatment that induces flower bud differentiation in strawberry and prevents rosette formation in Eustoma significantly increased the Delphinium elatum cut flower length. Moreover, ILTS was as effective as growing seedlings under cool conditions at preventing early-bolting. We analyzed the effects of six ILTS treatments that differed regarding the treatment temperature (5 and 10°C) and treatment cycle (3 days/3 days, 6 days/6 days, and 12 days/12 days; ambient conditions/cool and dark). Cut flowers were significantly longer with the 6 days/6 days treatment at 10°C than for the control treatment. Furthermore, repeating the ILTS treatment cycle (6 days ambient conditions/6 days at 10°C) a total of four times produced high-quality cut flowers regardless of the cultivar. Therefore, this ILTS treatment may be ideal for preventing early-bolting in D. elatum. en-copyright= kn-copyright= en-aut-name=KawaiMika en-aut-sei=Kawai en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuyasuMiwa en-aut-sei=Fukuyasu en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraYoshikuni en-aut-sei=Kitamura en-aut-mei=Yoshikuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= 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 Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cool storage kn-keyword=cool storage en-keyword=cut flower quality kn-keyword=cut flower quality en-keyword=high ambient temperature kn-keyword=high ambient temperature en-keyword=long day kn-keyword=long day en-keyword=Ranunculaceae kn-keyword=Ranunculaceae END start-ver=1.4 cd-journal=joma no-vol=95 cd-vols= no-issue=1 article-no= start-page=10 end-page=20 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=Comparison of Fruit Development, Ripening, and Transcriptome Dynamics in Taiwanese and Japanese Cultivars of Japanese Apricot (Prunus mume Sieb. et Zucc.) en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we compared changes in traits associated with fruit development and ripening in Taiwanese and Japanese cultivars of Japanese apricot (Prunus mume Sieb. et Zucc.). We also analyzed transcriptome profiles to comprehensively examine different fruit development and ripening patterns between the two groups in terms of fruit characteristics and gene expression. Early fruit development in Taiwanese cultivars ‘ST’ and ‘Ellching’ and the Japanese cultivar ‘Hakuo’ was ahead of that in other three Japanese cultivars (P1). From late April to early May, around the stone-hardening stage, the developmental differences decreased to the same level. Thereafter, Japanese cultivars showed rapid growth, whereas Taiwanese cultivars showed slower growth, reversing the developmental differences between these lines (P2). Ethylene production was not detected until the full ripening stage and was detected for the first time at this stage in five cultivars, except for ‘Ellching’ (P3). In contrast, no ethylene production was observed during the entire duration of fruit development in ‘Ellching’. A multidimensional scaling plot showed that the overall transcriptome profile changed according to the three stages (P1?P3) of fruit development and ripening. At P1, gene ontologies (GOs) related to cell division, such as the cell cycle and regulation of cyclin-dependent protein serine/threonine kinase activity, were enriched for differentially expressed genes downregulated in Taiwanese cultivars as compared with their expression in Japanese cultivars. At P2, GOs related to fruit development were not enriched, but some genes related to phytohormones, such as auxin, abscisic acid, and cytokinin, which are associated with fruit development and ripening, were differentially expressed. At P3, the expression of genes such as ACS, ACO, and PG, which are involved in ethylene biosynthesis, increased in response to increased ethylene production, but not in ‘Ellching’, which showed no ethylene production. Expression analysis of 115 NAC (NAM-ATAF1/2-CUC2) family genes, which are related to fruit ripening and ripening date in other fruit species, in the ‘Ellching’ genome revealed changes in expression of NAC056 and NAC073 corresponding to fruit development and ripening in Taiwanese and Japanese cultivars. We discuss the differences in fruit development and ripening behaviors between Taiwanese and Japanese cultivars in terms of physiological and transcriptome changes. en-copyright= kn-copyright= en-aut-name=KashiwamotoTomoaki en-aut-sei=Kashiwamoto en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiTakashi en-aut-sei=Kawai en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OeTakaaki en-aut-sei=Oe en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NumaguchiKoji en-aut-sei=Numaguchi en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraYuto en-aut-sei=Kitamura en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuboYasutaka en-aut-sei=Kubo en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukudaFumio en-aut-sei=Fukuda en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=Japanese Apricot Laboratory, Wakayama Fruit Tree Experiment Station kn-affil= affil-num=4 en-affil=Japanese Apricot Laboratory, Wakayama Fruit Tree Experiment Station kn-affil= affil-num=5 en-affil=Faculty of Agriculture, Setsunan University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=cell division kn-keyword=cell division en-keyword=ethylene production kn-keyword=ethylene production en-keyword=NAC kn-keyword=NAC en-keyword=phytohormone kn-keyword=phytohormone en-keyword=stone hardening kn-keyword=stone hardening END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=98 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=Genetic and phenotypic identities of Staphylococcus coagulans isolated from pustules of dogs with superficial bacterial folliculitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Staphylococcus coagulans, formerly called Staphylococcus schleiferi subsp. coagulans is the second most common isolate from skin lesions of dogs with superficial bacterial folliculitis (SBF). However, the clinical significance of S. coagulans in pustules of canine SBF remains uncertain. This study aimed to investigate the prevalence and genotypic and phenotypic diversity of S. coagulans isolated from pustules in two dogs with SBF.
Results Two dogs with SBF were included in this study. S. schleiferi/coagulans was isolated as the sole organism from three pustules in case #1, whereas it coexisted with S. pseudintermedius in two of seven pustules in case #2. S. pseudintermedius was the sole organism in the remaining five pustules in case #2. Whole genome sequences revealed that all isolates tested were annotated as S. coagulans. The isolates from the same pustules exhibited identical genotypic and phenotypic profiles, indicating clonal multiplication. S. coagulans isolated from different pustules exhibited similar yet distinct genotypic and phenotypic profiles.
Conclusions S. coagulans with identical genetic and phenotypic profiles can be identified as the sole pathogen or coexist with S. pseudintermedius in the pustules of the same dogs with SBF. en-copyright= kn-copyright= en-aut-name=OsumiTakafumi en-aut-sei=Osumi en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinomiyaYuuki en-aut-sei=Shinomiya en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WanganuttaraThamonwan en-aut-sei=Wanganuttara en-aut-mei=Thamonwan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImanishiIchiro en-aut-sei=Imanishi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimazakiYotaro en-aut-sei=Shimazaki en-aut-mei=Yotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IyoriKeita en-aut-sei=Iyori en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyodaYoichi en-aut-sei=Toyoda en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IdeKaori en-aut-sei=Ide en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishifujiKoji en-aut-sei=Nishifuji en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Animal Medical Center, Faculty of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=2 en-affil=Department of Veterinary Medicine, Faculty of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=3 en-affil=Department of Bacteriology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Kimberly and Eric J.

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=27 cd-vols= no-issue=5 article-no= start-page=2113 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=Fgf10 Gene Dosage from a Single Allele Is Insufficient for Forming Multilayered Epithelial Cells in the Murine Lacrimal Gland en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mutations in the fibroblast growth factor 10 (FGF10) gene in humans cause aplasia of the lacrimal and salivary glands (ALSG). In patients with ALSG, heterozygous loss-of-function mutations are found, and FGF10 haploinsufficiency results in the absence of these secretory organs. Lacrimal glands (LGs) are formed through epithelial thickening, budding, and branching morphogenesis. To compare the variable phenotypes of the Fgf10+/? Harderian glands (HGs) previously reported, we examined the development of LGs in wild-type (WT), Fgf10+/?, and Fgf10-null mice. Pax6 immunostaining was performed to visualize the LG primordia from embryonic day 15.5 (E15.5) onwards. In situ hybridization of the genes encoding the epithelial receptor of FGF10, FGFR2b, and its other ligands was performed to determine their potential involvement in LG development. LG primordia were not observed in Fgf10+/? mice bilaterally at E16.5 or later stages. At E15.5, budding from the developing conjunctival epithelium (CE) was observed in a small fraction of the Fgf10+/? LG primordia. In contrast, the Fgf10-null CE failed to promote budding. Among Fgf1, Fgf3, Fgf7, Fgf10, and Fgf22, Fgf10 was expressed in the mesenchyme surrounding developing LG epithelial cells, whereas Fgf1 was expressed in the LG epithelium of WT mice. Fgf7 was initially expressed in the mesenchyme surrounding the nascent LG epithelium, but its expression subsequently became diffused. Thus, we conclude that among the FGFR2b ligands, initial LG formation is dependent on the mesenchymal factors FGF10 and FGF7, and FGF1 is likely to function as an epithelial factor in the LG primordia. A single allele of Fgf10 was found to be insufficient to support the budding process during LG morphogenesis. en-copyright= kn-copyright= en-aut-name=IkedaShiori en-aut-sei=Ikeda en-aut-mei=Shiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TajikaYuki en-aut-sei=Tajika en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaHirofumi en-aut-sei=Fujita en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyaishiSatoru en-aut-sei=Miyaishi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Gumma Prefectural College of Health Sciences kn-affil= affil-num=4 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Legal Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fibroblast growth factor kn-keyword=fibroblast growth factor en-keyword=Fgf10 kn-keyword=Fgf10 en-keyword=Fgf1 kn-keyword=Fgf1 en-keyword=Fgf3 kn-keyword=Fgf3 en-keyword=Fgf7 kn-keyword=Fgf7 en-keyword=Fgf22 kn-keyword=Fgf22 en-keyword=Fgfr2b kn-keyword=Fgfr2b en-keyword=mouse kn-keyword=mouse en-keyword=lacrimal gland kn-keyword=lacrimal gland en-keyword=development kn-keyword=development 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=19 cd-vols= no-issue=1 article-no= start-page=13 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pan-cancer profiling links C1orf50 to DNA repair and immune modulation in ovarian cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background C1orf50 encodes a small, evolutionarily conserved protein, the function of which remains unclear. Its significance across various human cancers, particularly its specific role in ovarian cancer within an immunogenomic context, is not yet fully understood. Utilizing The Cancer Genome Atlas and single-cell RNA sequencing (scRNA-seq) public datasets, we conducted a comprehensive profiling of C1orf50 across multiple cancer types, with a particular focus on ovarian cancer, to investigate its associations with copy-number status, genomic instability, tumor programs, and the immune microenvironment.
Results Across cancer types, copy-number gain or amplification of C1orf50 was most frequent in ovarian cancer and closely tracked with higher messenger RNA levels. Higher C1orf50 expression was associated with a greater tumor mutational burden and homologous recombination deficiency, as indicated by gene-set patterns that suggested heightened cell-cycle and cellular stress responses accompanied by reduced oxidative phosphorylation, enrichment of regulatory T cells, and depletion of resting memory CD4 T cells. In ovarian cancer, focal events at chromosome 1p34.2 were accompanied by stepwise increases in C1orf50 expression by clinical stage and were linked to higher tumor mutational burden, homologous recombination deficiency, and greater loss of heterozygosity, together with more frequent gene alterations in BRCA1 or BRCA2. Immune composition clustered into profiles consistent with an immunosuppressive context in tumors with higher C1orf50 expression. The scRNA-seq data further revealed that cancer cells enhanced immune-suppressive interactions with various immune cell populations and diminished antigen-presentation signals. Analyses of genomic instability in ovarian cancer suggested mutational processes compatible with base-substitution patterns associated with cytidine deaminase activity and with insertion-deletion patterns characteristic of homologous recombination failure, while transcript-level patterns pointed to a broad downshift of canonical DNA repair activity with apparent compensatory adjustments in related pathways rather than a uniform change in any single pathway.
Conclusions The overexpression of C1orf50 characterizes an aggressive immunogenomic phenotype in ovarian cancer, distinguished by genomic instability, impaired DNA repair mechanisms, and extensive immunosuppression. These findings indicate that C1orf50 warrants consideration as a potential biomarker and a prospective target for therapeutic investigation. Furthermore, they advocate for the progression to prospective validation and functional studies to ascertain its clinical significance. en-copyright= kn-copyright= en-aut-name=RogachevskayaAnna en-aut-sei=Rogachevskaya en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtsuAkira en-aut-sei=Ohtsu en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChinVanessa D. en-aut-sei=Chin en-aut-mei=Vanessa D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Pe?aTirso en-aut-sei=Pe?a en-aut-mei=Tirso kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AraiSeiji en-aut-sei=Arai en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaAtsushi en-aut-sei=Tanaka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Harvard Medical School kn-affil= affil-num=4 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=5 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=6 en-affil=Department of Urology, Gunma University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Molecular Physiology, Faculty of Medicine, Graduate School of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=Pan-cancer analysis kn-keyword=Pan-cancer analysis en-keyword=DNA repair kn-keyword=DNA repair en-keyword=Gene expression kn-keyword=Gene expression en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment en-keyword=Immune evasion kn-keyword=Immune evasion en-keyword=Single-cell RNA-seq kn-keyword=Single-cell RNA-seq 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

kn-title=Effects of systemic ventricular assist combined with fenestration in failing Fontan: A theoretical analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biventricular assist for failing Fontan circulation remains challenging. Because fenestration effectively reduces stressed blood volume and central venous pressure in Fontan patients with increased pulmonary vascular resistance (PVR), systemic ventricular assist device (VAD) combined with fenestration may improve hemodynamics in failing Fontan patients with increased PVR who would require biventricular assist. To validate this hypothesis, we performed a computational hemodynamic simulation of the failing Fontan circulation using a lumped parameter model. We compared hemodynamic variables between the models with and without fenestration while the PVR index was increased sequentially from 3.01 to 6.81 Wood Units m2. Following VAD initiation and stressed blood volume reduction, central venous pressure was maintained at a lower level in the fenestration models. This positive effect was greater in the model with larger fenestration diameter. However, excessive fenestration caused significant desaturation. In failing Fontan circulation with elevated PVR, systemic VAD combined with fenestration significantly improved hemodynamics. en-copyright= kn-copyright= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HorioNaohiro en-aut-sei=Horio en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KisamoriEiri en-aut-sei=Kisamori en-aut-mei=Eiri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyaharaYoshinori en-aut-sei=Miyahara en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UemuraKoji en-aut-sei=Uemura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShishidoToshiaki en-aut-sei=Shishido en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=5 en-affil=Pediatric Heart Disease and Adult Congenital Heart Disease Center, Showa Medical University Hospital kn-affil= affil-num=6 en-affil=Department of Research Promotion and Management, National Cerebral and Cardiovascular Center kn-affil= affil-num=7 en-affil=Department of Research Promotion and Management, National Cerebral and Cardiovascular Center kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=Fontan circulation kn-keyword=Fontan circulation en-keyword=Hemodynamic simulation kn-keyword=Hemodynamic simulation en-keyword=Ventricular assist device kn-keyword=Ventricular assist device en-keyword=Fenestration kn-keyword=Fenestration en-keyword=Pulmonary vascular resistance kn-keyword=Pulmonary vascular resistance END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=9 article-no= start-page=4363 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gaseous CO2 electrolysis: latest advances in electrode and electrolyzer technologies toward abating CO2 emissions en-subtitle= kn-subtitle= en-abstract= kn-abstract=The conversion of CO2 into multicarbon (C2+) products via electrochemical reduction is considered a key technology for the sustainable production of fuels and chemicals. The performance of high-rate gaseous CO2 electrolysis is governed by interrelated factors such as the electrocatalysts, electrodes, electrolytes, and cell architectures. Despite the intensive focus on catalyst research, systematic studies addressing the other components remain scarce, leaving critical gaps in our understanding toward achieving higher performance in CO2 electrolysis systems. The nanoscale design of catalyst surface electronic structures and the macroscale design of electrodes and electrolyzer architectures both influence the overall activity of the electrochemical system. In designing macroscale components, it is necessary to establish benchmarks based on a comprehensive evaluation of CO2 emissions for the entire electrolysis process, because these parameters are directly linked to output metrics such as current density and cell voltage under practical operating conditions. This review summarizes recent advances in electrodes and electrolyzers, and through life-cycle assessment (LCA), evaluates key performance indicators (KPIs) for achieving negative emissions and assesses the current technology readiness of CO2 electrolysis. en-copyright= kn-copyright= en-aut-name=KamiyaKazuhide en-aut-sei=Kamiya en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakasoneSora en-aut-sei=Nakasone en-aut-mei=Sora kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuriharaRyo en-aut-sei=Kurihara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueAsato en-aut-sei=Inoue en-aut-mei=Asato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IrieHazuki en-aut-sei=Irie en-aut-mei=Hazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakahataShoko en-aut-sei=Nakahata en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=TaniguchiSatoshi en-aut-sei=Taniguchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NguyenThuy T.

In this study, we conducted a literature search and systematic review focusing on the outcomes after surgery for older cancer patients.
Methods: Literature focusing on surgical treatment for older cancer patients was extracted from Japanese clinical practice guidelines for gastric cancer, lung cancer, colorectal cancer, liver cancer, and gynecological cancers (uterine body, uterine cervix, ovary, and external genitalia and vagina). Outcomes were reviewed, and committee members determined the strength of evidence on a four-point scale (A to D), with A being the highest and D being the lowest.
Results: Older cancer patients tend to have a higher incidence of postoperative complications and postoperative syndromes, and their expected survival is generally shorter compared to non-older patients. When extensive surgeries such as para-aortic lymph node dissection and/or resection with other organs are performed for older cancer patients, the postoperative mortality rates tend to increase compared to non-older patients.
Conclusion: Surgical treatments for older cancer patients tend to result in higher morbidity even when the patients are in good health status. Nevertheless, there is still a possibility that a certain fraction of the patients achieve treatment outcomes comparable to those of non-older patients. Therefore, surgical indication and procedure for older cancer patients should be carefully determined based on surgical invasiveness and patient tolerability. en-copyright= kn-copyright= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OfuchiTakashi en-aut-sei=Ofuchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueDaisuke en-aut-sei=Inoue en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugimotoKen en-aut-sei=Sugimoto en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurofushiKeiko en-aut-sei=Murofushi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkuyamaToru en-aut-sei=Okuyama en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanukiShigeaki en-aut-sei=Watanuki en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ImamuraChiyo en-aut-sei=Imamura en-aut-mei=Chiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaiDaisuke en-aut-sei=Sakai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakuraiNaomi en-aut-sei=Sakurai en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WatanabeKiyotaka en-aut-sei=Watanabe en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TamuraKazuo en-aut-sei=Tamura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SaekiToshiaki en-aut-sei=Saeki en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=IshiguroHiroshi en-aut-sei=Ishiguro en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Surgery, Kyushu University Beppu Hospital kn-affil= affil-num=3 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, University of Fukui kn-affil= affil-num=5 en-affil=Department of General Geriatric Medicine, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Division of Radiation Oncology, Department of Radiology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital kn-affil= affil-num=7 en-affil=Department of Psychiatry/Palliative Care Center, Nagoya City University West Medical Center kn-affil= affil-num=8 en-affil=National Center for Global Health and Medicine, National College of Nursing kn-affil= affil-num=9 en-affil=Advanced Cancer Translational Research Institute, Showa University kn-affil= affil-num=10 en-affil=Department of Frontier Science for Cancer and Chemotherapy, Osaka University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Cancer Solutions Co.

Euryhaline elasmobranchs face the severest water-influx potential in fresh water (FW), as they retain high concentrations of urea even in hypotonic environments. To elucidate how they overcome this osmotic challenge, we assessed urine output in conscious euryhaline red stingrays (Hemitrygon akajei). Following acclimation to 5% diluted seawater, the stingrays increased urinary output by 87-fold?the greatest change observed in vertebrates?partly due to 6.8-fold increase in glomerular filtration rate (GFR). In the nephron, expressions of Aquaporin-1 (Aqp1), Aqp3, and Aqp15 were strongly downregulated in FW, indicating that tubular diuresis bridges the gap between GFR and final urine volume. Meanwhile, FW-acclimation upregulated Aqp1 and Aqp4 in the distinct bundle structure, which promotes urea reabsorption. Euryhaline elasmobranchs resolve the huge osmotic challenge of FW by excreting massive amounts of water and retaining osmolytes including urea through coordinated regulation of GFR and Aqp expressions. en-copyright= kn-copyright= en-aut-name=AburataniNaotaka en-aut-sei=Aburatani en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiWataru

kn-subtitle= en-abstract= kn-abstract=Climate change education (CCE) in primary schools is increasingly recognised as essential, yet how teachers interpret and enact CCE across diverse local contexts remains underexplored. This study examines how Mongolian primary school teachers working with students aged 6?11 in urban and rural contexts interpret and teach climate change, with particular attention to the role of place. Drawing on semi-structured interviews with 20 teachers across contrasting contexts, the study explores how environmental, cultural, and institutional conditions shape teachers’ pedagogical interpretations and classroom practices. Data were analysed using reflexive thematic analysis, informed by conceptual frameworks that position place as an active mediator of teaching and learning. Findings show that rural teachers frequently integrated traditional ecological knowledge and lived environmental experience to connect global climate processes with locally observable ecological change, emphasising livelihood impacts and intergenerational ecological memory. Urban teachers, by contrast, framed climate change through anthropogenic pressures such as air pollution, waste, and infrastructure constraints, foregrounding feasible individual actions within everyday school contexts. Across both settings, teachers exercised place-responsive pedagogical judgement by selectively adapting climate content to local realities while navigating curriculum constraints and workload pressures. The study contributes a place-responsive account of teachers’ pedagogical judgement in CCE, demonstrating how place functions not only as context but as a condition shaping pedagogical feasibility. en-copyright= kn-copyright= en-aut-name=GerelkhuuShinetsetseg en-aut-sei=Gerelkhuu en-aut-mei=Shinetsetseg kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Fiel’ardhKhalifatulloh en-aut-sei=Fiel’ardh en-aut-mei=Khalifatulloh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiHiroki en-aut-sei=Fujii en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YembuuBatchuluun en-aut-sei=Yembuu en-aut-mei=Batchuluun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DembereldorjUuriintuya en-aut-sei=Dembereldorj en-aut-mei=Uuriintuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=4 en-affil=Geography Department, Mongolian National University of Education kn-affil= affil-num=5 en-affil=Lifelong Learning and Distance Education Department, Mongolian National University of Education kn-affil= en-keyword=Climate change education kn-keyword=Climate change education en-keyword=place-responsive education kn-keyword=place-responsive education en-keyword=primary school teachers kn-keyword=primary school teachers en-keyword=pedagogical judgement kn-keyword=pedagogical judgement en-keyword=traditional ecological knowledge kn-keyword=traditional ecological knowledge en-keyword=urban?rural contexts kn-keyword=urban?rural contexts en-keyword=Mongolia kn-keyword=Mongolia END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=5 article-no= start-page=e2025GL119568 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical Conductivity of Amorphous and Molten CaCO3 at High Pressures and Its Implications for Mantle Conductivity Anomalies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Impedance spectrometry experiments have been conducted on CaCO3 up to 15 GPa and 2,100 K to identify its state under high pressure. The melting temperature of CaCO3 was also determined by the falling of a Re sphere observed via X-ray radiography. The phase transition from aragonite to the amorphous phase does not cause a leap in the Electrical conductivity (EC), while a drastic increase in the EC, by 1.5?2.0 log units, only occurs with the onset of melting. The EC of amorphous CaCO3 is comparable to other hydrous mantle minerals at similar pressure and temperature conditions. The required fraction of amorphous CaCO3 implies that it can be excluded from the potential origins responsible for the observed high EC anomalies in the upper mantle. If the conductivity anomalies are induced by the presence of carbonate, a low-degree melting of carbonate-bearing peridotite is anticipated. 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=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChenQi en-aut-sei=Chen en-aut-mei=Qi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuTony en-aut-sei=Yu en-aut-mei=Tony kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhangDongzhou en-aut-sei=Zhang en-aut-mei=Dongzhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChenBin en-aut-sei=Chen en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=4 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=5 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=6 en-affil=School of Ocean and Earth Science and Technology, University of Hawaii at Manoa kn-affil= affil-num=7 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=47 end-page=60 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=Ultrafast Time-Compressive CMOS Image Sensors Based on Multitap Charge Modulators for Filming Light-In Flight en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ultrafast time-compressive CMOS image sensors based on multitap charge modulators can capture light-in flight using coded exposure masks on the focal plane. Transient images can then be reconstructed using iterative methods or deep learning models. Although the image sensor is based on indirect time-of-flight (ToF) image sensors, the reconstructed images are equivalent to those captured by direct ToF (D-ToF) image sensors. Important design parameters of the image sensor include the pixel block size and the number of taps of the charge modulator. Several constraints regarding the charge transfer of the multitap charge modulator, the hamming distance between exposure codes at adjacent timings, and the minimal time window duration must be considered when designing exposure codes. The influence of these factors on the fidelity of the reconstructed images is analyzed numerically. The results show that a pixel block size of 4×4 is optimal and that four or more taps are required for light detection and ranging (LiDAR) applications when 32 transient images of light-in flight are reconstructed. To demonstrate LiDAR in a scene with multipath interference, two objects were observed through a weakly diffusive sheet. The temporal resolution, as defined by the clock period of the exposure codes, was 1.65 ns. Multiple reflections were reconstructed using an iterative method (TVAL3) and a deep learning model (ADMM-Net). Although the waveforms of optical pulses reconstructed by TVAL3 are distorted, the amplitudes are more accurate. Conversely, although ADMM-Net reconstructs sharper optical pulses, the amplitudes are inaccurate. To achieve the shorter temporal resolution required for time-resolved diffuse optical tomography (DOT) and fluorescence lifetime imaging (FLIm), the feasibility of heterodyne compression was demonstrated through simulation. en-copyright= kn-copyright= en-aut-name=KagawaKeiichiro en-aut-sei=Kagawa en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiDaisuke en-aut-sei=Hayashi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakuraArashi en-aut-sei=Takakura en-aut-mei=Arashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmekiYuto en-aut-sei=Umeki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=YasutomiKeita en-aut-sei=Yasutomi en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawahitoShoji en-aut-sei=Kawahito en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChaeYoungcheol en-aut-sei=Chae en-aut-mei=Youngcheol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagaharaHajime en-aut-sei=Nagahara en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=2 en-affil=Graduate School of Integrated Science and Technology, Shizuoka University kn-affil= affil-num=3 en-affil=Faculty of Engineering, Shizuoka University kn-affil= affil-num=4 en-affil=Graduate School of Integrated Science and Technology, Shizuoka 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=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=7 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=8 en-affil=Department of Electrical and Electronic Engineering, Yonsei University kn-affil= affil-num=9 en-affil=D3 Center, The University of Osaka kn-affil= en-keyword=CMOS image sensor kn-keyword=CMOS image sensor en-keyword=compressive imaging kn-keyword=compressive imaging en-keyword=computational photography (CP) kn-keyword=computational photography (CP) en-keyword=multitap charge modulator kn-keyword=multitap charge modulator en-keyword=transient imaging kn-keyword=transient imaging END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue= article-no= start-page=101740 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=Evaluation of platinum-free interval and chemotherapeutic effect of subsequent platinum-containing chemotherapy in patients with recurrent ovarian cancer initially treated with bevacizumab: SGSG018/Intergroup study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The effect of bevacizumab on platinum sensitivity in recurrent ovarian cancer remains poorly understood. This study examined the association between platinum-free interval (PFI) and sensitivity to subsequent platinum-containing chemotherapy in patients with first relapsed ovarian cancer after bevacizumab chemotherapy.
Methods: We retrospectively analyzed patients who received platinum-based chemotherapy for platinum-sensitive recurrence between November 2013, and December 2019, and who were initially treated by platinum-based chemotherapy with concurrent and maintenance bevacizumab. The primary endpoint was response rate to subsequent chemotherapy after various periods of PFI. The relevance between response rate and PFI was assessed for each PFI of 6?12, 12?24 and ≧24 months using Cochran-Armitage test. The secondary endpoint was progression-free survival (PFS) defined as time from chemotherapy for first recurrence to subsequent progression and response rate to subsequent chemotherapy for each treatment-free interval since last administration of bevacizumab (Bev-TFI).
Results: A total of 77 patients were eligible. The median PFI until first recurrence was 12 months (range: 6?43). The response rates of subsequent chemotherapy for patients with PFI of 6?12, ?12-24, and 24 months were 42 %, 65 %, and 80 %, showing a linear trend (p < 0.05). Median PFS among the three groups was 8 (95 %CI: 6.7?9.2), 11 (95 %CI: 8.4?13.5) and 13 months (95 % CI: 5.4?20.5) (p = 0.107, log-rank test), respectively. By contrast, no linear trend was observed between Bev-TFI and response rate (p = 0.225)
Conclusion: In patients with first relapse of primary ovarian cancer and bevacizumab beyond progression, the prolonged PFS effect of bevacizumab does not seem to affect sensitivity to subsequent platinum-based chemotherapy. en-copyright= kn-copyright= en-aut-name=TanakaTamaki en-aut-sei=Tanaka en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

kn-abstract=Background. The superior mesenteric artery (SMA) approach is crucial for the successful implementation of robot-assisted pancreatoduodenectomy (RPD). Herein, we present a novel technique, the mesenteric route SMA-first approach, for RPD.
Patients and Methods. A 20-year-old woman with a 50 mm intraductal papillary mucinous neoplasm underwent RPD. As the tumor was large and located close to the mesenteric vessels, we developed the mesenteric route SMA-first approach.
Results. Following the mesenteric Kocher maneuver, the mesenteric route SMA-first approach was applied. With appropriate retraction of the pancreatic head, dissection around the mesenteric vessels was performed and their branches were divided. The uncinate process dissection (PL, ph II) was performed via the mesenteric route. This approach facilitated dorsal dissection, particularly around the large tumor. After dissection of the hepatoduodenal ligament, the remaining pancreatic nerve plexus (PL ph I) was dissected. Finally, the pancreas was divided on the superior mesenteric vein, and the specimen was resected. Operative time was 390 min with minimal blood loss.
Conclusions. The mesenteric route SMA-first approach enables uncinate process dissection via the mesenteric route. This technique may be a safe and feasible option for selected patients, such as nonobese individuals with a large pancreatic head tumor near major vessels. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoAtene en-aut-sei=Ito en-aut-mei=Atene kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YanagiharaTsubasa en-aut-sei=Yanagihara en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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= en-keyword=Robotic pancreaticoduodenectomy kn-keyword=Robotic pancreaticoduodenectomy en-keyword=Superior mesenteric artery approach kn-keyword=Superior mesenteric artery approach en-keyword=Mesenteric route kn-keyword=Mesenteric route END start-ver=1.4 cd-journal=joma no-vol=133 cd-vols= no-issue= article-no= start-page=111546 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robotic pancreatoduodenectomy for a giant duodenal leiomyoma: A case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Duodenal leiomyomas are rare mesenchymal tumors. To date, several studies have reported on the safety and feasibility of surgical intervention for duodenal leiomyomas. However, minimally invasive surgery has rarely been performed in cases with duodenal leiomyomas. Herein, we present a case of a giant duodenal leiomyoma successfully treated with robotic pancreatoduodenectomy (RPD).
Presentation of case: A 74-year-old man was referred to our hospital with a 6.5 cm duodenal tumor accompanied by gastrointestinal bleeding. The tumor was located in the second portion of the duodenum. Considering the tumor size and location, RPD was performed. Using the mesenteric Kocker maneuver, the posterior side of the duodenum was safely dissected, and the tumor was resected. The operative time was 373 min, with an estimated blood loss of 10 mL. The patient was followed up for 7 months with no recurrence.
Discussion: To the best of our knowledge, this is the first to highlight the clinicopathological findings of a patient with duodenal leiomyoma undergoing RPD. To date, there have been 19 cases, including our case, reporting surgically treated duodenal leiomyoma. Treatment strategies should be decided depending on tumor characteristics, including the size, location, and histology of the tumor.
Conclusion: We present a rare case of a giant duodenal leiomyoma that was successfully treated with RPD. Minimally invasive surgery can be safe and an alternative for the treatment of large duodenal tumors. en-copyright= kn-copyright= en-aut-name=DoitaSusumu en-aut-sei=Doita en-aut-mei=Susumu 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=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko 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=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=Duodenal leiomyomas kn-keyword=Duodenal leiomyomas en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Pancreatoduodenectomy kn-keyword=Pancreatoduodenectomy END start-ver=1.4 cd-journal=joma no-vol=410 cd-vols= no-issue=1 article-no= start-page=171 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robotic distal pancreatectomy using two-surgeon technique (TAKUMI-4): a technical note and initial outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose With the increasing use of minimally invasive distal pancreatectomy, the use of robotic distal pancreatectomy (RDP) is also increasing worldwide. Standardized surgical protocols are essential for safe implementation of RDP. In this study, we present our surgical protocol and initial outcomes of RDP using “two-surgeon technique”.
Methods Our standard RDP protocol included a two-surgeon technique for cooperation, rationality, and education. Short-term outcomes of RDP were also investigated. This retrospective study included 77 consecutive patients who underwent RDP at our institution between April 2021 and January 2025.
Results The median operative time, estimated blood loss, and postoperative hospital stay were 214 min (interquartile range [IQR], 176?253), 10 mL (IQR, 0?50), and 9 days (IQR, 8?10), respectively. A textbook outcome was achieved in 84.4% of patients. Moreover, superior outcomes of RDP (n?=?77) compared with those of laparoscopic distal pancreatectomy (n?=?62) were confirmed in this study.
Conclusion Using the two-surgeon technique, we successfully standardized and introduced the RDP program. The two-surgeon technique can contribute to the safe introduction of RDP and expansion of the program. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Distal pancreatectomy kn-keyword=Distal pancreatectomy en-keyword=Robotic surgery: minimally invasive surgery kn-keyword=Robotic surgery: minimally invasive surgery en-keyword=Training kn-keyword=Training en-keyword=Outcomes kn-keyword=Outcomes END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=5 article-no= start-page=3137 end-page=3145 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250404 dt-online= en-article= kn-article= en-subject= kn-subject= 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

A 60-year-old woman underwent radical resection of a 25-cm MLS in the right thigh after receiving neoadjuvant radiotherapy. The patient developed a 6-cm solitary pancreatic metastasis of the MLS 2?years later. Because no other distant metastases were detected, robotic SPDP (Warshaw technique) was performed. The operative time was 140?min with minimal blood loss. Follow-up at 3?months showed no recurrence. To our knowledge, this is the first report of a case of metachronous pancreatic metastasis of MLS successfully treated with robotic SPDP.

To explore the safety and efficacy of standard chemotherapy combined with central nervous system (CNS)-directed therapy, we conducted a multicentre, single-arm, phase 2 trial in untreated IVLBCL patients without CNS involvement at diagnosis (PRIMEUR-IVL). In the primary analysis, the PRIMEUR-IVL study demonstrated 2-year progression-free survival (PFS) of 76% and 2-year overall survival (OS) of 92% with a low incidence (3%) of secondary CNS involvement (sCNSi).
Methods We present a prespecified final analysis of the PRIMEUR-IVL study including 5-year PFS, OS and cumulative incidence of sCNSi. Participants were enrolled between June 2011 and July 2016, and the data cutoff date for the final analysis was 16 November 2021. The trial was registered in the UMIN Clinical Trial Registry (UMIN000005707) and the Japan Registry of Clinical Trials (jRCTs041180165).
Findings With a median follow-up of 7.1 years (interquartile range 5.6?8.7), 5-year PFS in all 37 eligible patients was 68% (95% confidence interval [CI] 50%?80%) and OS was 78% (95% CI 61%?89%). No additional sCNSi was observed after the primary analysis. Severe adverse events after the primary analysis were grade 4 neutropenia (n = 1) and grade 4 myelodysplastic syndrome that did not require specific treatment (n = 1). Eight deaths occurred during the observation period after enrolment, due to primary disease (n = 6), sepsis (n = 1) and unknown sudden death (n = 1).
Interpretation Long-term follow-up data demonstrated durable response for PFS and OS, and low cumulative incidence of sCNSi, indicating the efficacy of standard chemotherapy combined with CNS-directed therapy for untreated IVLBCL patients.

discuss subgroup analyses in clinical practice guidelines? Evaluation procedure of the clinical and statistical relevancy en-subtitle= kn-subtitle= en-abstract= kn-abstract=The results of subgroup analyses of clinical trials are important reference information when considering the generalizability of a study treatment, i.e., providing the best treatment for each individual patient. The results of subgroup analyses are often presented in publications, etc. as forest plots focusing on patient backgrounds. However, it is important to fully understand and grasp some of the issues involved in subgroup analyses and to interpret the results carefully to apply them in clinical practice. Although the literature includes some reports on how subgroup analyses should be evaluated and handled for the purpose of establishing medical practice guidelines, most of the papers have mainly evaluated the reliability of subgroup analyses from a statistical perspective; few of them have incorporated clinical importance in their evaluations. Therefore, in December 2019, we established a Subgroup Analysis Review Committee consisting of oncologists specializing in lung cancer treatment and statistical experts among the members of the Guidelines Review Committee of the Japanese Lung Cancer Association, with the aim of appropriately reflecting subgroup analysis in Japanese lung cancer practice guidelines. We developed a new evaluation strategy to incorporate clinical aspects as well as reliability assessment. Specifically, on the basis of a clinical and statistical review of the problems with subgroup analyses presented as clinical trial results, we developed criteria and procedures to ensure consistency and fairness in the citation of clinical guidelines. en-copyright= kn-copyright= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiuraSatoru en-aut-sei=Miura en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OyaYuko en-aut-sei=Oya en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoTomohiro en-aut-sei=Sakamoto en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaKentaro en-aut-sei=Tanaka en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeraokaShunsuke en-aut-sei=Teraoka en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoriseMasahiro en-aut-sei=Morise en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoritaSatoshi en-aut-sei=Morita en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Niigata Cancer Center Hospital kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine and Allergy, Fujita Health University kn-affil= affil-num=4 en-affil=Division of Respiratory Medicine and Rheumatology, Department of Multidisciplinary Internal Medicine, Tottori University kn-affil= affil-num=5 en-affil=Graduate School of Medical Sciences, Research Institute for Diseases of the Chest, Kyushu University kn-affil= affil-num=6 en-affil=Internal Medicine III, Wakayama Medical University kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, Nagoya University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Biomedical Statistics and Bioinformatics, Graduate School of Medicine, Kyoto University kn-affil= en-keyword=Subgroup analysis kn-keyword=Subgroup analysis en-keyword=Guideline kn-keyword=Guideline en-keyword=Lung cancer kn-keyword=Lung cancer END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e86575 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Retreatment With EGFR-Tyrosine Kinase Inhibitor After Disease Progression Following Gefitinib Induction and Chemoradiotherapy in EGFR-Mutant Stage III Non-small Lung Cancer: An Efficacy and Safety Analysis of the LOGIK0902/OLCSG0905 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and objective: We had previously conducted a phase II study (LOGIK0902/OLCSG0905 study) involving the eight-week administration of gefitinib, followed by cisplatin-based chemoradiotherapy, to treat locally advanced, epidermal growth factor receptor (EGFR)-mutated, non-small cell lung cancer (NSCLC). Despite favorable overall survival outcomes, more than half of the patients relapsed after the protocol therapy, highlighting the need to clarify the clinical significance of retreatment with EGFR-tyrosine kinase inhibitors (TKIs). We investigated the efficacy and safety of EGFR-TKI retreatment after disease progression.
Materials and methods: We included 14 patients who relapsed after the protocol treatment and received any type of EGFR-TKI as post-progression treatment in this sub-analysis. We evaluated the efficacy and safety of retreatment with EGFR-TKI in these patients.
Results: Among the 14 patients, 11 (78.6%) responded to the induction of gefitinib in the treatment protocol. After relapse, 9/14 patients (64.3%) received gefitinib, 3/14 (21.4%) received afatinib, and 2/14 (14.3%) received erlotinib monotherapy, respectively. The median duration of post-progression EGFR-TKI treatment was 17.9 (0.7-45.5) months. The overall response rate (ORR) and disease control rate were 64.3% [9/14 patients; 95% confidence interval (CI): 35.1%-87.2%] and 85.7% (12/14 patients; 95% CI: 57.2%-98.2%), respectively. The median progression-free survival (PFS) and median survival durations after the initiation of EGFR-TKI retreatment were 11.8 months (95% CI: 5.7-20.7 months) and 47.4 months (95% CI: 31.8 months to not estimable), respectively. Adverse events were comparable to those previously reported.
Conclusions: Patients with disease progression after protocol therapy demonstrated sensitivity to retreatment with an EGFR-TKI, with acceptable safety. en-copyright= kn-copyright= en-aut-name=SaekiSho

the Small Intestine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Myeloid sarcoma is a rare extramedullary tumor of immature myeloid cells that is often associated with acute myeloid leukemia (AML). We herein report an 81-year-old man who presented with intestinal obstruction due to myeloid sarcoma of the small intestine. Diagnostic challenges were overcome using double-balloon enteroscopy and a biopsy, which confirmed the diagnosis of myeloid sarcoma. The patient subsequently developed AML but responded well to chemotherapy. This case underscores the importance of considering myeloid sarcoma in the differential diagnosis of small-bowel tumors. Highlighting the significance of a histological analysis, even in patients presenting with small bowel obstruction, the early diagnosis and treatment are crucial for improving outcomes, particularly in patients without a history of hematologic malignancies. 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=MatsuedaKatsunori en-aut-sei=Matsueda en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KametakaDaisuke en-aut-sei=Kametaka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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 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 Pathology, 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= en-keyword=acute myeloid leukemia kn-keyword=acute myeloid leukemia en-keyword=double-balloon enteroscopy kn-keyword=double-balloon enteroscopy en-keyword=myeloid sarcoma kn-keyword=myeloid sarcoma en-keyword=small intestine kn-keyword=small intestine 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.

In unresectable cases, the survival period is short despite combination therapy with cytotoxic anticancer agents and immune checkpoint inhibitors. The usefulness of immune checkpoint inhibitors against malignant tumors with microsatellite instability-high (MSI-H) mutations was shown in the KEYNOTE158 study; however, data for intrahepatic cholangiocarcinoma are insufficient. In the present case, a 65-year-old man with intrahepatic cholangiocarcinoma and lymph node metastasis could not be treated with a combination of gemcitabine, CDDP, and S-1. A comprehensive cancer genomic profiling (CGP) test showed MLH1 pathogenic mutation and MSI-H. When pembrolizumab was administered, the tumor shrinkage effect was rapidly observed, which was sustained even after 30 months. No pathogenic mutations were observed in the germline test, and MSI-high was considered to be due to the MLH1 pathogenic mutation occurring sporadically in somatic cells. MSI-H intrahepatic cholangiocarcinoma is extremely rare. However, because pembrolizumab is expected to be effective, CGP testing should be actively performed. en-copyright= kn-copyright= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=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=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Microsatellite instability (MSI)-high kn-keyword=Microsatellite instability (MSI)-high en-keyword=Tumor mutation burden (TMB)-high kn-keyword=Tumor mutation burden (TMB)-high en-keyword=Intrahepatic cholangiocarcinoma kn-keyword=Intrahepatic cholangiocarcinoma en-keyword=Comprehensive genome profiling kn-keyword=Comprehensive genome profiling END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=e79651 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gastric Metastasis of Renal Cell Carcinoma Initially Diagnosed by Esophagogastroduodenoscopy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Here, we report a rare case of renal cell carcinoma (RCC) initially detected as a gastric metastasis.

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.

A trigonometric forcing based on vector potential is combined with uniform random numbers to create a spatially homogeneous forcing field. The analysis is performed using large-eddy simulation (LES) with the Smagorinsky model as the subgrid scale model. The results demonstrate that steady flows are generated regardless of the presence of phase randomization, successfully forming isotropic turbulence. In contrast, for anisotropic turbulent fields, the addition of phase randomization reduces the degree of anisotropy, indicating a smoothing effect on the anisotropy of the flow. en-copyright= kn-copyright= en-aut-name=MinamiKoki en-aut-sei=Minami en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroki en-aut-sei=Suzuki en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKento en-aut-sei=Tanaka en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=3027 cd-vols= no-issue=1 article-no= start-page=012008 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fundamental examination of coherent structure model prediction using vortex cores in a two-dimensional Taylor’s analytical solution en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study focuses on the possibility that flow around vortex tubes in turbulence may resemble laminar flow, and aims to describe the characteristics of turbulent fields using analytical solutions to the governing equations.

We report a pediatric case of erythromelalgia in a patient who developed posterior reversible encephalopathy syndrome (PRES), without any cutaneous signs.
Case presentation: A previously healthy 12-year-old girl presented to our pediatric clinic with burning extremity pain that had persisted for 6 weeks. The patient was treated with analgesics; however, the pain was refractory to these agents. Seven days after the first visit, she developed afebrile seizures and was transferred to our hospital. Her initial blood pressure was 139/105 mmHg (+2.0 SD), and brain magnetic resonance imaging revealed high intensity areas in the bilateral parietal and occipital lobes, leading to a diagnosis of PRES. Her blood pressure was difficult to control with anti-hypertensive agents. Burning pain in her extremities was relieved by cooling and worsened by warming. Although erythema was not observed in her hands or legs, erythromelalgia was suspected based on the characteristic nature of her pain. Intravenous lidocaine was administered for diagnosis, which was dramatically effective. After initiating mexiletine, the burning pain in her extremities disappeared, and hypertension improved. A final diagnosis of erythromelalgia with PRES was made.
Conclusion: A history of temperature-dependent pain relief and deterioration are important indicators of disease diagnosis, even if patients indicate a lack of erythema or warmth. Physicians should be aware that persistent pain due to erythromelalgia can lead to refractory hypertension and development of PRES. en-copyright= kn-copyright= en-aut-name=SuzukiKengo en-aut-sei=Suzuki en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArakawaKyosuke en-aut-sei=Arakawa en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigeharaKenji en-aut-sei=Shigehara en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatric Acute Diseases, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Erythromelalgia kn-keyword=Erythromelalgia en-keyword=Posterior reversible encephalopathy syndrome kn-keyword=Posterior reversible encephalopathy syndrome en-keyword=Hypertension kn-keyword=Hypertension en-keyword=Child kn-keyword=Child END start-ver=1.4 cd-journal=joma no-vol=115 cd-vols= no-issue= article-no= start-page=9 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Soil nitrogen dynamics affected by the fine roots of canopy trees in Eastern Hokkaido, Japan kn-title=北海道東部の森林において林冠木の細根が土壌窒素動態に与える影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Plants release mixtures of labile organic matter from their fine roots (root exudates) into the surrounding soil (rhizosphere). Partly due to the release of root exudates, microbial community structures and their activities within the rhizosphere differ significantly from those in other soil areas (bulk soil). Consequently, nutrient cycling processes, including nitrogen mineralization, are accelerated in the rhizosphere, facilitating nutrient acquisition by plants. This phenomenon, known as the rhizosphere effect, has been repeatedly reported in studies of herbaceous plants; however, the impact of canopy tree fine roots on soil nitrogen dynamics through the effect in forest ecosystems remains largely unknown. Here, I introduce our research investigating the root exudates and rhizosphere effects of the fine roots of canopy trees, Quercus crispula, and how these fine roots affect soil nitrogen dynamics. The quantity of root exudates varied daily rather than seasonally, with solar radiation having a strong and positive effect on the amounts. However, even after leaf fall, root exudation was observed. In the rhizosphere, specific bacterial communities were present regardless of season, while ectomycorrhizal fungal populations were higher than in the bulk soil only in summer. Extracellular enzymatic activity relating to nitrogen cycling was higher in the rhizosphere than in the bulk soil across seasons. Nitrogen uptake by the tree was likely lower in winter and spring, leading to labile nitrogen accumulation in the rhizosphere during these periods. On an annual basis, however, the impact of fine roots on apparent inorganic nitrogen dynamics was minor. These results suggest that the canopy tree, Q. crispula, accelerates soil nitrogen cycling through root exudation and rhizosphere effects, regardless of season, while the acceleration of the cycle and the utilization of available nitrogen are well-balanced annually, thereby avoiding unnecessary carbon investment. en-copyright= kn-copyright= en-aut-name=NakayamaMasataka en-aut-sei=Nakayama en-aut-mei=Masataka kn-aut-name=中山理智 kn-aut-sei=中山 kn-aut-mei=理智 aut-affil-num=1 ORCID= affil-num=1 en-affil=Course of Environmental Ecology kn-affil=環境生態学コース en-keyword=Quercus crispula kn-keyword=Quercus crispula en-keyword=root exudates kn-keyword=root exudates en-keyword=rhizosphere effect kn-keyword=rhizosphere effect en-keyword=nitrogen dynamics kn-keyword=nitrogen dynamics en-keyword=nitrogen uptake kn-keyword=nitrogen uptake END start-ver=1.4 cd-journal=joma no-vol=115 cd-vols= no-issue= article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Branching Characteristics and Their Contribution to Yield in Everbearing Strawberry Cultivars under Forced Cultivation en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Enhancing continuous flowering in cultivated strawberries may result in insufficient photosynthetic products due to the lower limit of leaf number on each lateral shoot, leading to reduced yield and fruit quality. If strawberries could differentiate an appropriate number of tillers and allow each tiller to grow autonomously with sufficient leaf number on each lateral shoot, rather than flowering continuously on the main bud alone, plants could achieve high yields while preventing plant weakening and fruit quality deterioration. Therefore, this study evaluated branching characteristics of everbearing strawberry cultivars under forcing cultivation to identify cultivars with moderate tillering and moderately low continuous flowering. Pot experiments revealed that the number of tillers was high in ‘Summer Princess’ and ‘Miyazaki-natsuharuka’ but low in ‘Summer Berry’ and ‘Suzuakane’. This trend was independent of total number of lateral shoots, nodal position of first inflorescence, and the number of leaves on each lateral shoot, which serve as indicators of continuous flowering ability. Among seven tested cultivars, ‘DT17’ and ‘Miyazaki-natsuharuka’ showed intermediate values with 2.1 - 2.5 tillers per plant and 6.7 - 7.7 leaves on each lateral shoots. These cultivars showed yields of 747.0 - 1,028.5 g per plant under forcing cultivation, which were higher than other cultivars, along with consistent fruit quality. These results suggest that improving branching characteristics is a practical approach to enhancing fruit productivity in strawberries. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=SoneKazuyoshi en-aut-sei=Sone en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorishitaMasami en-aut-sei=Morishita en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Kyushu Okinawa Region Agricultural Research Center, NARO kn-affil= affil-num=2 en-affil=Kyushu Okinawa Region Agricultural Research Center, NARO kn-affil= affil-num=3 en-affil=Kyushu Okinawa Region Agricultural Research Center, NARO kn-affil= en-keyword=branching characteristics kn-keyword=branching characteristics en-keyword=continuous flowering ability kn-keyword=continuous flowering ability en-keyword=crown kn-keyword=crown en-keyword=strawberry kn-keyword=strawberry en-keyword=tiller kn-keyword=tiller END
