In this study, the RNAi efficiency of PA8 nanomicelle/siRNA complexes was enhanced by modifying the nanomicelles with the photosensitizer DY750 and the tumor-homing peptide iRGD. The conjugation of DY750 to the nanomicelles facilitated endosomal escape of the nanomicelle/siRNA complexes, enabling the cytosolic release of siRNA. Additionally, the incorporation of iRGD improved RNAi delivery efficiency in the AsPC-1 pancreatic ductal adenocarcinoma cell line. PA8-DY750-iRGD nanomicelle complexes loaded with siRNA against polo-like kinase 1 (PLK1) achieved an 80% reduction in PLK1 mRNA levels in AsPC-1 cells and a moderate 28% knockdown in NCI-N87 gastric cancer cells. Notably, no RNAi effect was observed in noncancerous 1C3D3 pancreatic cells or HEK293T kidney cells, underscoring the selectivity of this system for AsPC-1 cells. These findings highlight the potential of PA8-DY750-iRGD nanomicelle complexes as a targeted therapeutic platform for specific cancers, particularly pancreatic cancer. en-copyright= kn-copyright= en-aut-name=HakimTaufik Fatwa Nur en-aut-sei=Hakim en-aut-mei=Taufik Fatwa Nur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimotoShoumu en-aut-sei=Fujimoto en-aut-mei=Shoumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Peptide nanomicelles kn-keyword=Peptide nanomicelles en-keyword=siRNA kn-keyword=siRNA en-keyword=Near infrared light kn-keyword=Near infrared light en-keyword=Targeted delivery kn-keyword=Targeted delivery en-keyword=Photosensitizer kn-keyword=Photosensitizer END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=10464 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Liquid–liquid phase separation by caged coacervating peptides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liquid–liquid phase separation is an important biomolecular process in the formation of membraneless intracellular organelles that has inspired the development of artificial droplet systems. We developed caged coacervating peptides (CCPs) based on a histidine-rich squid beak protein sequence. The peptides were caged with a photodeprotectable (7-diethylaminocoumarin-4-yl)methoxycarbonyl group. The CCPs formed coacervates in the caged state and were partially dispersed upon blue-light irradiation. Photo-uncaging occurred rapidly, inducing coacervate dispersion. A mutant CCP with reduced π–π interactions exhibited efficient photo-dependent disassembly and enabled the encapsulation and release of a fluorescently labeled adenosine 5′-triphosphate (Bodipy-ATP) upon irradiation. These CCPs offer an efficient light-controlled approach for biomolecular encapsulation within coacervates and targeted drug delivery. en-copyright= kn-copyright= en-aut-name=BandoAkinari en-aut-sei=Bando en-aut-mei=Akinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanazakiYuuki en-aut-sei=Kanazaki en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TojoRika en-aut-sei=Tojo en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Caged coacervating peptide kn-keyword=Caged coacervating peptide en-keyword=Liquid–liquid phase separation kn-keyword=Liquid–liquid phase separation en-keyword=Light kn-keyword=Light END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue= article-no= start-page=50 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=「数学的活動」の最適化 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　算数・数学教育では「数学的な見方・考え方を働かせ、数学的活動を通して、『数学的に考える』」という資質・能力を育成する方向が示されている(2017)。考える力の育成を叫ぶけれども、「個別最適な学び」「協働的な学び」という指導方法・授業スタイルに眼を奪われている。数学的活動は、「数学的に考える力」を育成する中心的な学習活動であるが、数学的な活動の在り方を分析・検討することには熱心でなく、教科書どおりのきまり切った活動をさせている。数学的活動には、外的活動と内的活動があり、どんな数学的活動にすれば最適化できるのかは容易ではない。外的な操作的活動は数理的なイメージを生み出す思考を促す。内的な数学的活動は直観的な数理的イメージを内面化し言語や記号と結びつけて､算数の概念や原理を形成する思考を生成する。外的及び内的な数学的活動は､相互に関連しつつ､シンクロしながら数理的思考を促進していくので、固定的に捉えないで､弾力的・機能的に捉えることが大切である。どのような活動にすれば、数学的に考える力は創発し、生成することができるのか、数学的活動の最適化を探究することは喫緊の課題である。 en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=黒﨑東洋郎 kn-aut-sei=黒﨑 kn-aut-mei=東洋郎 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=森川唯 kn-aut-sei=森川 kn-aut-mei=唯 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学名誉教授 affil-num=2 en-affil= kn-affil=倉敷市立玉島南小学校教諭 en-keyword=活動主義の算数教育 kn-keyword=活動主義の算数教育 en-keyword=考える力 kn-keyword=考える力 en-keyword=数学的活動 kn-keyword=数学的活動 en-keyword=最適化 kn-keyword=最適化 END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue= article-no= start-page=42 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=「統合的・発展的に考える力」を育成する算数科の授業 ～６年「立体の体積」の学びを通して～ en-subtitle= kn-subtitle= en-abstract= kn-abstract=　VUCAの時代（※）を生き抜く子どもたちに必要な資質・能力の育成が喫緊の課題とされている。算数科では永年，「統合的・発展的に考える力」を育成すべき資質・能力の中核に置いてきた。この力はVUCAの時代にも通用する力であり，子どもが「自ら課題を見付け，自ら学び，自ら考える」（確かな学力、1996）原動力になる力であると考える。しかしながら，未だそれを十分達成することはできていない。それは，「統合的・発展的に考える力」を育成するシステムが示されておらず，プロセスが確立されていないからであると考える。

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 µM), 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

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=宮﨑善郎 kn-aut-sei=宮﨑 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=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.

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=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. Additionally, we compared differences in physical activity levels by position during soccer matches while wearing LC devices. The results showed no significant differences in physical or fitness characteristics between positions. 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. It also suggested the usefulness of evaluating physical activity levels during matches over time. kn-abstract=　中学生34人を対象とし，身体・体力特性とサッカー試合中の身体活動量について，ポジションに着目して比較・検討した．その結果，身体・体力特性についてはポジション間に有意な差は認められなかった．歩数ではポジション間で有意差が認められ，ライトサイドバックが少なく，センターミッドフィルダーが高かった．強度別身体活動量時間の割合ではポジション間で有意差が認められ，ライトサイドバックが低く，センターミッドフィルダーが高かった．以上のことから，本研究の対象中学生ではポジション間で身体・体力特性には有意差が認められないが，サッカー試合中の身体活動量ではポジション間で差が生じることが示唆された． en-copyright= kn-copyright= en-aut-name=NATSUMEDATakaaki en-aut-sei=NATSUMEDA en-aut-mei=Takaaki kn-aut-name=棗田尊貴 kn-aut-sei=棗田 kn-aut-mei=尊貴 aut-affil-num=1 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=2 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=Okayama University Graduate School of Education kn-affil=岡山大学学術研究院教育学域 en-keyword=サッカー (Soccer) kn-keyword=サッカー (Soccer) en-keyword=中学生 (Junior High School Students) kn-keyword=中学生 (Junior High School Students) en-keyword=加速度計 (Accelerometer) kn-keyword=加速度計 (Accelerometer) en-keyword=新体力テスト (New Physical Fitness Test) kn-keyword=新体力テスト (New Physical Fitness Test) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学教育推進機構 教師教育開発センター紀要 第16号 全文（一括ダウンロード用） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=55 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Low Temperature Formation of Dense Yttria-Stabilized Zirconia Layer Using Hot Isostatic Pressing kn-title=熱間静水圧加圧法を用いたイットリア安定化ジルコニア緻密層の低温形成 en-subtitle= 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.

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=

Making における患者参加の諸相と課題の考察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper traces the historical development of decision-making models in healthcare while exploring the meaning and practical significance of “patient participation” within the shared decision-making (SDM) framework. 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.

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=32 cd-vols= no-issue=1 article-no= start-page=33 end-page=44 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=Large-scale rainfall characteristics at the heavy rainfall event around the western Japan during 5–7 July 2018 kn-title=2018年7月5日〜7日の西日本豪雨における広域降水特性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Large-scale rainfall characteristics at the heavy rainfall event around the western Japan for 5–7 July 2018 were analyzed with use of the 10-mimute precipitation data at the surface meteorological observation stations of the Japan Meteorological Agency, and so on. 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=61 cd-vols= no-issue= article-no= start-page=101 end-page=120 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=Relationships between Gender Role, Ambivalent Sexism and Vocational Motivation kn-title=性役割と両面価値的性差別主義における就業動機との関連 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HAPPOSuzuha en-aut-sei=HAPPO en-aut-mei=Suzuha kn-aut-name=八方涼葉 kn-aut-sei=八方 kn-aut-mei=涼葉 aut-affil-num=1 ORCID= en-aut-name=SUMIOKAKyoko en-aut-sei=SUMIOKA en-aut-mei=Kyoko kn-aut-name=住岡恭子 kn-aut-sei=住岡 kn-aut-mei=恭子 aut-affil-num=2 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=85 end-page=99 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=Economic Value Generated by Innovations in Photographic Technology kn-title=写真技術のイノベーションが創出する経済価値 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MIYAZAKISatoru en-aut-sei=MIYAZAKI en-aut-mei=Satoru kn-aut-name=宮崎悟 kn-aut-sei=宮崎 kn-aut-mei=悟 aut-affil-num=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=31 end-page=46 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=Current Status and Challenges in Reproductive Health and Rights in South Australia:Insights from Adelaide kn-title=南オーストラリア州（アデレード）のリプロダクティブ・ヘルス＆ライツをめぐる現状と課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SAITOKeisuke en-aut-sei=SAITO en-aut-mei=Keisuke kn-aut-name=齋藤圭介 kn-aut-sei=齋藤 kn-aut-mei=圭介 aut-affil-num=1 ORCID= en-aut-name=SUGANOSetsuko en-aut-sei=SUGANO en-aut-mei=Setsuko kn-aut-name=菅野摂子 kn-aut-sei=菅野 kn-aut-mei=摂子 aut-affil-num=2 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=東京科学大学社会連携・DE&I本部 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=1 end-page=20 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=Student Perceptions of Group Work in Multicultural Collaborative Learning : A Case Study in an Area Studies Class Using GIS Software kn-title=多文化共修のためのグループワークから学生は何を感じたのか？ ― GIS ソフトを使用した地域研究授業からの一考察 ― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=INAMORITakao en-aut-sei=INAMORI en-aut-mei=Takao kn-aut-name=稲森岳央 kn-aut-sei=稲森 kn-aut-mei=岳央 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院共通教育・グローバル領域 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，①System １を行動生成メカニズムとして再定義した点，②意思決定主体と権力構造を再定義した点，③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，④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，⑤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=夏扎提古丽沙吾提 kn-aut-sei=夏扎提古丽 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=24 cd-vols= no-issue=1 article-no= start-page=146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=MMP-3 cleavage of Lamin A induces pro-migratory nuclear 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=16 cd-vols= no-issue=5 article-no= start-page=2339 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concentration-Dependent Synergistic Interfacial Interactions Between Multifunctional Acrylate and Silane Coupling Agents in an Organic–Inorganic Nanohybrid Material en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synergistic effects of a multifunctional acrylate and a long-chain silane coupling agent were investigated in an organic–inorganic nanohybrid material. We tested the bond strength of nanohybrid composites treated with experimental primers containing silane coupling agents—3-methacryloxypropyl trimethoxysilane (γ-MPTS) or 8-methacryloxyoctyl trimethoxysilane (8-MOTS)—with or without multifunctional acrylates—trimethylolpropane triacrylate (A-TMPT) or dipentaerythritol hexaacrylate (A-DPH). Shear bond strength was evaluated after 24 h of water storage at 37 °C. Untreated control and silane-only groups exhibited low shear bond strengths (e.g., control: 2.4 ± 2.0 MPa) and failed exclusively at the adhesive interface. While addition of A-TMPT did not significantly improve bond strength, addition of A-DPH produced significantly higher shear bond strengths. Highest strength was achieved with 30% 8-MOTS and A-DPH (22.4 ± 6.1 MPa), followed by 20% γ-MPTS and A-DPH (19.0 ± 7.0 MPa), and A-DPH groups produced cohesive failures. Regardless of the silane used (γ-MPTS or 8-MOTS), incorporating A-DPH in the primer consistently yielded superior bond strengths, indicating a promising strategy for improved adhesion for such nanohybrid systems. These findings provide new insights into optimizing resin–filler interfacial interactions and may contribute to the development of restorative materials with improved long-term clinical durability. en-copyright= kn-copyright= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KodamaNaoki en-aut-sei=Kodama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshizaneMai en-aut-sei=Yoshizane en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkiyamaKentaro en-aut-sei=Akiyama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=2 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=3 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Dental School, Okayama University kn-affil= affil-num=5 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=6 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=silane coupling kn-keyword=silane coupling en-keyword=multifunctional acrylate kn-keyword=multifunctional acrylate en-keyword=bond strength kn-keyword=bond strength en-keyword=resin kn-keyword=resin END start-ver=1.4 cd-journal=joma no-vol=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=21 cd-vols= no-issue=50 article-no= start-page=e06926 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=Collagen Signaling via DDR1 Exacerbates Barriers to Macromolecular Drug Delivery in a 3D Model of Pancreatic Cancer Fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fibrosis is a significant barrier to drug delivery in pancreatic ductal adenocarcinoma (PDAC) and contributes to its dismal prognosis. 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=

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 sheathを鎖骨下動脈に留置して椎骨動脈撮影（vertebral artery angiography: VAG）を行う方法の有用性を報告する．当院で本血管撮影を施行した症例の患者背景や合併症を評価した．企図した4例，5血管でVAGを施行でき，合併症も認めなかった．体位変換も腹臥位における穿刺部の観察も簡便であり，カテーテルの操作性にも優れ，VAGを容易に施行することができた．また，管球を頭側から移動する際の術野との干渉も最小限に抑えられた．本方法は利点が多く，有用な血管撮影方法であり，頭蓋頚椎移行部動静脈瘻の手術における一助となり得ると考える．

Employing the FLint system, the research analyzes the speech patterns and instructional behaviors of both supporters and learners in classroom settings characterized by community-oriented features. The analysis yielded the following findings: (1) the mean number of utterances produced by supporters was greater than that of learners; and (2) the average amount of indirect behavior in supporters’ utterances by slightly exceeded that of direct behavior. In the interactive style, supporters were observed to actively employ subcategories of indirect behaviors—such as questioning, using ideas of learners, and repeating learner responses—in order to scaffold the learners’ process of verbalizing their intended messages. kn-abstract= 本研究では，地域型日本語教育のモデル構築に向け，地域型の特徴を有する教室内での支援者および参加者の発話や教授行動の傾向を明らかにすべく，外国語相互作用分析システムを用い，オンラインによるボランティア教室におけるインターアクションの分析を行った。分析の結果，（1）支援者の平均発話数が学習者より多いこと，（2）支援者の発話における間接的行動の割合が直接的行動よりもやや高いことが示された。「おしゃべり型の教育」では，学習者が伝えたいことを言語化していくプロセスの中で，間接的行動の下位分類の「質問」「学習者の意図の利用」「学習者の回答の繰り返し」等を支援者が積極的に使用し支援していることが分かった。 en-copyright= kn-copyright= en-aut-name=SUESHIGEMiwa en-aut-sei=SUESHIGE en-aut-mei=Miwa kn-aut-name=末繁美和 kn-aut-sei=末繁 kn-aut-mei=美和 aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 en-keyword=地域型日本語教育 kn-keyword=地域型日本語教育 en-keyword=おしゃべり型 kn-keyword=おしゃべり型 en-keyword=オンラインボランティア教室 kn-keyword=オンラインボランティア教室 en-keyword=F-システム kn-keyword=F-システム en-keyword=インターアクション kn-keyword=インターアクション END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=106742 end-page= 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=Inscribed-type spherical speed reducer with uniform reduction ratio in all directions en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spherical motor is an actuator that can generate rotational motion about all three orthogonal axes. However, it is difficult to obtain high output torque from most electromagnetic spherical motors, primarily due to limitations inherent in electromagnetic actuators, such as restricted magnetic force and thermal constraints. Since its torque cannot be increased using planar gears, spherical speed reducers that transmit rotational torque along three orthogonal axes through sphere-to-sphere contact are required. One major limitation of conventional spherical speed reducers is that their size increases significantly as the reduction ratio becomes higher. To address this issue, we propose a novel inscribed-type spherical speed reducer, in which the deceleration mechanism is integrated within the output sphere. This configuration enables a more compact design, reducing the overall size to approximately half that of conventional designs. To predict the angular velocity and transmitted torque, theoretical models for the rotation and torque transmission of the speed reducer were developed. According to the proposed model, the reduction ratio of the spherical speed reducer is 1/3. To verify the validity of these models, experiments were conducted to measure angular velocity and torque. The theoretical results agreed well with the experimental results. In addition, the theoretical torque exhibited an average relative error of 1.63 % compared to the experimental result. Therefore, it was confirmed that the rotation and torque transmission models were valid. These results demonstrate that a reduction ratio can be obtained in all directions of the 3-DOF of the spherical speed reducer, unlike conventional 1-DOF reducers. en-copyright= kn-copyright= en-aut-name=NaramuraSeiya en-aut-sei=Naramura en-aut-mei=Seiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TonegawaKoichi en-aut-sei=Tonegawa en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanoTomoaki en-aut-sei=Yano en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GofukuAkio en-aut-sei=Gofuku en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KasashimaNagayoshi en-aut-sei=Kasashima en-aut-mei=Nagayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, 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=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=Okayama Prefectural University kn-affil= affil-num=6 en-affil=National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=7 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Inscribed-type spherical speed reducer kn-keyword=Inscribed-type spherical speed reducer en-keyword=Rotation and torque transmission kn-keyword=Rotation and torque transmission en-keyword=Friction kn-keyword=Friction en-keyword=Spherical motor kn-keyword=Spherical motor en-keyword=Three-axis rotation kn-keyword=Three-axis rotation END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=279 end-page=285 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=OCHI Seiko Quantitative analysis of Northern Wei history kn-title=大知聖子著『計量的分析を用いた北魏史研究』 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HASEGAWAHirokazu en-aut-sei=HASEGAWA en-aut-mei=Hirokazu kn-aut-name=長谷川大和 kn-aut-sei=長谷川 kn-aut-mei=大和 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=20 end-page=39 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=Radiocarbon dating, dietary habits, and genetic characteristics of ancient skeletal remains excavated from the Inome Cave Site in Shimane Prefecture kn-title=島根県猪目洞窟遺跡出土人骨の年代・食性・遺伝的特徴 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper reports on the integrative research findings of the human bones excavated from the Inome Cave Site in Shimane Prefecture, based on dietary estimation using carbon and nitrogen isotope analysis, radiocarbon dating, and whole genome analysis. The dates of the analyzed human bones span a wide range, from the Middle to Late Kofun period, the Nara period to the Early Heian period, and the Middle to Late Heian period, indicating that the Inome Cave Site was continuously used as a burial place. Dietary habits were a mixture of C3 resources (C3 plants and terrestrial animals that consumed C3 plants) and marine resources, with individual variations in the intake of marine and terrestrial resources. A correlation was observed between differences in dietary habits and individual variations in the Jomon ratio in the nuclear genome, with individuals who consumed higher amounts of marine resources tending to have a higher Jomon ratio. This suggests that individuals with different backgrounds were buried in the same site due to interactions with surrounding settlements. en-copyright= kn-copyright= en-aut-name=KANZAWA-KIRIYAMAHideaki en-aut-sei=KANZAWA-KIRIYAMA en-aut-mei=Hideaki kn-aut-name=神澤秀明 kn-aut-sei=神澤 kn-aut-mei=秀明 aut-affil-num=1 ORCID= en-aut-name=TAKIGAMIMai en-aut-sei=TAKIGAMI en-aut-mei=Mai kn-aut-name=瀧上舞 kn-aut-sei=瀧上 kn-aut-mei=舞 aut-affil-num=2 ORCID= en-aut-name=KAKUDATsuneo en-aut-sei=KAKUDA en-aut-mei=Tsuneo kn-aut-name=角田恒雄 kn-aut-sei=角田 kn-aut-mei=恒雄 aut-affil-num=3 ORCID= en-aut-name=SPEIDELLeo en-aut-sei=SPEIDEL en-aut-mei=Leo kn-aut-name=シュパイデルレオ kn-aut-sei=シュパイデル kn-aut-mei=レオ aut-affil-num=4 ORCID= en-aut-name=HELLENTHALGarrett en-aut-sei=HELLENTHAL en-aut-mei=Garrett kn-aut-name=ヘレンタールガレット kn-aut-sei=ヘレンタール kn-aut-mei=ガレット aut-affil-num=5 ORCID= en-aut-name=BIRDNancy en-aut-sei=BIRD en-aut-mei=Nancy kn-aut-name=バードナンシー kn-aut-sei=バード kn-aut-mei=ナンシー aut-affil-num=6 ORCID= en-aut-name=KAWAIYousuke en-aut-sei=KAWAI en-aut-mei=Yousuke kn-aut-name=河合洋介 kn-aut-sei=河合 kn-aut-mei=洋介 aut-affil-num=7 ORCID= en-aut-name=NCBN Controls WGS Consortium en-aut-sei=NCBN Controls WGS Consortium en-aut-mei= kn-aut-name=NCBN コントロール WGS コンソーシアム kn-aut-sei=NCBN コントロール WGS コンソーシアム kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SAKAMOTOMinoru en-aut-sei=SAKAMOTO en-aut-mei=Minoru kn-aut-name=坂本稔 kn-aut-sei=坂本 kn-aut-mei=稔 aut-affil-num=9 ORCID= en-aut-name=KAMEDAYuichi en-aut-sei=KAMEDA en-aut-mei=Yuichi kn-aut-name=亀田勇一 kn-aut-sei=亀田 kn-aut-mei=勇一 aut-affil-num=10 ORCID= en-aut-name=ADACHINoboru en-aut-sei=ADACHI en-aut-mei=Noboru kn-aut-name=安達登 kn-aut-sei=安達 kn-aut-mei=登 aut-affil-num=11 ORCID= en-aut-name=SHINODAKen-ichi en-aut-sei=SHINODA en-aut-mei=Ken-ichi kn-aut-name=篠田謙一 kn-aut-sei=篠田 kn-aut-mei=謙一 aut-affil-num=12 ORCID= en-aut-name=SAITOUNaruya en-aut-sei=SAITOU en-aut-mei=Naruya kn-aut-name=斎藤成也 kn-aut-sei=斎藤 kn-aut-mei=成也 aut-affil-num=13 ORCID= en-aut-name=HAMADATatsuhiko en-aut-sei=HAMADA en-aut-mei=Tatsuhiko kn-aut-name=濵田竜彦 kn-aut-sei=濵田 kn-aut-mei=竜彦 aut-affil-num=14 ORCID= affil-num=1 en-affil=Division of Human Evolution, Paleontology and Anthropology, National Museum of Nature and Science, Tsukuba City, Ibaraki Prefecture kn-affil= affil-num=2 en-affil=Division of Human Evolution, Paleontology and Anthropology, National Museum of Nature and Science, Tsukuba City, Ibaraki Prefecture kn-affil= affil-num=3 en-affil=Department of Legal Medicine, Interdisciplinary Graduate School of Medicine and Engineering, University of Yamanashi kn-affil= affil-num=4 en-affil=Center for Interdisciplinary Theoretical and Mathematical Sciences, RIKEN kn-affil= affil-num=5 en-affil=Department of Genetics, Evolution and Environment, University College London Genetics Institute (UGI), University College London kn-affil= affil-num=6 en-affil=Department of Genetics, Evolution and Environment, University College London Genetics Institute (UGI), University College London kn-affil= affil-num=7 en-affil=Genome Medical Science Project, National Institute of Global Health and Medicine, National Institute for Health Security kn-affil= affil-num=8 en-affil= kn-affil= affil-num=9 en-affil=National Museum of Japanese History kn-affil= affil-num=10 en-affil=Division of Human Evolution, Paleontology and Anthropology, National Museum of Nature and Science, Tsukuba City, Ibaraki Prefecture kn-affil= affil-num=11 en-affil=Department of Legal Medicine, Interdisciplinary Graduate School of Medicine and Engineering, University of Yamanashi kn-affil= affil-num=12 en-affil=National Museum of Nature and Science kn-affil= affil-num=13 en-affil=National Institute of Genetics kn-affil= affil-num=14 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= en-keyword=Inome Cave Site kn-keyword=Inome Cave Site en-keyword=human bone kn-keyword=human bone en-keyword=radiocarbon dating kn-keyword=radiocarbon dating en-keyword=dietary habits kn-keyword=dietary habits en-keyword=ancient genome kn-keyword=ancient genome END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=19 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=The “Russian Flu” pandemic in Japan, 1889-1891: A social-historical perspective kn-title=日本における「ロシアかぜ」流行の社会史的分析 ―1889 -1891 年パンデミックと日本社会― en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study offers a social-historical analysis of the “Russian flu” pandemic in Japan (1889–1891). Due to scarce statistical data, the study relies primarily on contemporary newspapers and magazines. It identifies two distinct epidemic waves: the first in spring-summer 1890, and the second from late 1890 to spring 1891. The first wave, though widespread, was overshadowed by a concurrent cholera epidemic and caused relatively few deaths, whereas the second wave was far more lethal and generated widespread fear. At the time, influenza remained an “unknown disease”, with unclear etiology and no established treatments. People responded with diverse measures, from purchasing patent medicines and using folk remedies to symbolic practices such as "disease naming" (osome-kaze). The crisis also renewed attention to historical records of earlier influenza-like epidemics in Japan. In contrast, by the time of the later “Spanish flu” pandemic, advances in bacteriology had already rendered influenza a medically defined disease. This comparison highlights how shifting medical knowledge shaped societal responses. The findings not only corroborate previous excess-mortality analyses but also provide new historical insights into how societies have historically confronted pandemics. en-copyright= kn-copyright=

into the divergent evolution of a photosystem I supercomplex in Euglena gracilis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem I (PSI) forms supercomplexes with light-harvesting complexes (LHCs) to perform oxygenic photosynthesis. Here, we report a 2.82-angstrom cryo–electron microscopy structure of the PSI-LHCI supercomplex from Euglena gracilis, a eukaryotic alga with secondary green alga-derived plastids. The structure reveals a PSI monomer core with eight subunits and 13 asymmetrically arranged LHCI proteins. Euglena LHCIs bind diadinoxanthin, which is one of the carotenoids typically associated with red-lineage LHCs and is not present in the canonical LHCI belt found in green-lineage PSI-LHCI structures. Phylogenetic analysis shows that the Euglena LHCIs originated from LHCII-related clades rather than from the green-lineage LHCI group and that the nuclear-encoded PSI subunit PsaD likely originated from cyanobacteria via horizontal gene transfer. These observations indicate a mosaic origin of the Euglena PSI-LHCI. Our findings uncover a noncanonical light-harvesting architecture and highlight the structural and evolutionary plasticity of photosynthetic systems, illustrating how endosymbiotic acquisition and lineage-specific adaptation shape divergent light-harvesting strategies. en-copyright= kn-copyright= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoRuna en-aut-sei=Sakamoto en-aut-mei=Runa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumazawaMinoru en-aut-sei=Kumazawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshikawaTakahiro en-aut-sei=Ishikawa en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakabayashiAtsushi en-aut-sei=Takabayashi en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagaoRyo en-aut-sei=Nagao en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Institute of Low Temperature Science, Hokkaido University kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Institute of Agricultural and Life Sciences, Academic Assembly, Shimane University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Institute of Low Temperature Science, Hokkaido University kn-affil= affil-num=9 en-affil=Faculty of Agriculture, Shizuoka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=45 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Magnetic Detection of Cancer Cells Using Tumor-Homing Peptide-Modified Magnetic Nanoparticles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Magnetic nanoparticles (MNPs) provide a platform for target detection because of their magnetic responsiveness to alternating magnetic fields (AMFs). We developed a detection method using MNPs modified with tumor-homing peptides (THPs), PL1 and PL3, which selectively bind to protein components enriched in malignant tissues. THP-MNPs were synthesized using maleimide-PEG-NHS linkers and characterized using transmission electron microscopy. Human glioblastoma cancer U87MG and normal tissue-derived HEK293 cells were incubated with THP-MNPs, and the magnetic signals were measured using a high-temperature superconducting quantum interference device (SQUID) magnetometer under an AMF (1.06 kHz). Dark-field microscopy confirmed the preferential binding of THP-MNPs to U87MG cells. In the absence of cells, THP-MNPs exhibited AMF-dependent signal enhancement, which correlated with particle size reduction due to THP release. This increase was completely suppressed in the presence of U87MG cells, indicating a strong THP-mediated interaction. PL3-MNPs exhibited superior discrimination between malignant and non-malignant cells. These results demonstrate that SQUID-based magnetic measurements using THP-MNPs enable rapid and label-free cancer cell detection. en-copyright= kn-copyright= en-aut-name=ZhouShengli en-aut-sei=Zhou en-aut-mei=Shengli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurutaniYuji en-aut-sei=Furutani en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamashitaKei en-aut-sei=Yamashita en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakoSakuya en-aut-sei=Kako en-aut-mei=Sakuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=magnetic nanoparticle kn-keyword=magnetic nanoparticle en-keyword=tumor-homing peptide kn-keyword=tumor-homing peptide en-keyword=superconducting quantum interference devices kn-keyword=superconducting quantum interference devices END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=20 article-no= start-page=4309 end-page=4317 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251009 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of Autonomous and Ca2+/Calmodulin-Dependent Activities of CaMKK Isoforms In Vitro and in Mouse Tissues en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ca2+/CaM-dependent protein kinase kinase (CaMKK) phosphorylates and activates downstream kinases, including CaMKI, CaMKIV, PKB, and AMPK, regulating various cellular functions such as neuronal morphogenesis, metabolic control, and pathophysiological pathways, such as cancer progression. CaMKKα/1 is tightly regulated by an autoinhibitory mechanism. CaMKKβ/2 activity is highly Ca2+/CaM-independent (autonomous activity) in vitro and Ca2+/CaM-dependent in cultured cells. Whether these two activity states of CaMKKβ/2 exist in vivo and the detailed regulatory mechanisms for the transition of both activity states remain unclear due to the difficulty in distinguishing the two activity states. In this study, we detected Ca2+-dependent and autonomous CaMKK activity in HeLa cells and successfully separated both activity states of CaMKKβ/2 in mouse brain and testis extracts using a recently developed CaMKK inhibitor (TIM-063)-coupled sepharose, which binds to the catalytic domain in the active state but not in the autoinhibited state. Furthermore, lambda protein phosphatase treatment converted the Ca2+/CaM-dependent form to the autonomous form of CaMKKβ/2, which was not affected by Ala mutation of Ser128, Ser132, and Ser136. The two activity forms of CaMKKβ/2 had equivalent Ca2+/CaM-binding ability. The findings demonstrate the presence of autonomous and Ca2+/CaM-dependent forms of CaMKKβ/2 independently in mouse tissues and cultured cells. The transition of these states of CaMKKβ/2 may be dynamically regulated by the phosphorylation/dephosphorylation of serine residues in the N-terminal regulatory domain. en-copyright= kn-copyright= en-aut-name=OhtsukaSatomi en-aut-sei=Ohtsuka en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChenYerun en-aut-sei=Chen en-aut-mei=Yerun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikawaTeruhiko en-aut-sei=Ishikawa en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakagamiHiroyuki en-aut-sei=Sakagami en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuizuFutoshi en-aut-sei=Suizu en-aut-mei=Futoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=5 en-affil=Department of Anatomy, Kitasato University School of Medicine kn-affil= affil-num=6 en-affil=Clinical Examination Department, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=7 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=13 article-no= start-page=2097 end-page=2104 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Heat Transfer Enhancement by Forming Bridges among Reactive Particles in a Packed Bed Reactor of a Solid-gas Chemical Heat Storage System en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, the enhancement of the thermal output of solid-gas chemical heat storage systems was investigated. Bridges made of high-thermal conductivity materials were formed among reactive particles by drying a slurry which contained graphite powder as a thermal additive and dispersant in a packed-bed reactor. First, the effect of the volume ratio of the dispersant on effective thermal conductivity was investigated. The optimum volume ratio of dispersant to graphite powder was determined. Furthermore, repetitive bridge formation increased the effective thermal conductivity. Based on these results, we investigated the thermal response of the energy-discharge process. Consequently, the temperature distribution in the radial direction of the reactor decreased owing to the formation of bridges. In addition, the thermal energy generated by the adsorption of water vapor onto the adsorbent was effectively transferred to the reactor wall. The thermal output was estimated based on the experimental results. The thermal output was increased by the formation of bridges. en-copyright= kn-copyright= en-aut-name=NakasoKoichi en-aut-sei=Nakaso en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimadaKenji en-aut-sei=Shimada en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MinoYasushi en-aut-sei=Mino en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotohKuniaki en-aut-sei=Gotoh en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life Natural Science and Technology, Okayama University kn-affil= en-keyword=chemical heat storage kn-keyword=chemical heat storage en-keyword=packed bed kn-keyword=packed bed en-keyword=bridge among particles kn-keyword=bridge among particles en-keyword=heat transfer enhancement kn-keyword=heat transfer enhancement en-keyword=effective energy utilization kn-keyword=effective energy utilization END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=1 article-no= start-page=31 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structure and acid resistance of fluoride-treated hydroxyapatite particles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Topical fluoride is used in clinical dentistry to prevent dental caries. The primary reaction product formed on the tooth surface after topical fluoride application is calcium fluoride (CaF2). In this study, we investigated the effect of deposited CaF2 on the acid resistance of fluoride-treated hydroxyapatite (HAp). Commercial HAp particles were treated with two types of fluoride-containing acetic acid-sodium acetate (Ac-AcNa) buffer solutions, with and without the addition of phosphate ions. X-ray diffraction (XRD) and nuclear magnetic resonance (NMR) analyses confirmed the formation of fluorine-substituted hydroxyapatite (F-HAp), along with a hydration layer containing calcium phosphate and CaF2. Phase composition analysis revealed that the presence of phosphate ions in the fluoride treatment solution reduced the amount of CaF2 deposited. Acid resistance evaluation and phase composition analysis indicated that the initial dissolution rate of the fluoride-treated HAp in Ac-AcNa buffer solutions decreased on surfaces densely covered with CaF2 particles. en-copyright= kn-copyright= en-aut-name=HayakawaSatoshi en-aut-sei=Hayakawa en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AndoKazuki en-aut-sei=Ando en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshiokaTomohiko en-aut-sei=Yoshioka en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty 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=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Hydroxyapatite kn-keyword=Hydroxyapatite en-keyword=Fluoride treatment kn-keyword=Fluoride treatment en-keyword=Calcium fluoride kn-keyword=Calcium fluoride en-keyword=Acid resistance kn-keyword=Acid resistance END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=1 article-no= start-page=24 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preparation of brookite-type titanium dioxide particle layer on titanium surfaces via hydrothermal treatment and evaluation of in vitro apatite-forming ability en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we prepared a brookite-type titanium dioxide particle layer on the surface of titanium substrates via hydrothermal treatment in aqueous urea solutions containing sodium chloride (NaCl) and examined its in vitro apatite-forming ability. Increasing the urea concentration suppressed the formation of anatase-type titanium dioxide on the titanium substrate, forming a particle layer composed of pure brookite-type titanium dioxide. The size and packing density of brookite-type titanium dioxide particles formed on the titanium substrate increased with the NaCl concentration in a 7.0 mol·dm−3 urea solution. When titanium substrates hydrothermally treated in aqueous solutions of 7.0 mol·dm−3 urea and 2.0 mol·dm−3 NaCl were soaked in a simulated body fluid for various periods up to 7 d, the substrate surface was densely covered with hemispherical apatite particles (5.3 µm in diameter) within 3 d, indicating that the brookite-type titanium dioxide particle layer had an excellent apatite-forming ability comparable to that of the anatase-type titanium dioxide particle layer. en-copyright= kn-copyright= en-aut-name=HayakawaSatoshi en-aut-sei=Hayakawa en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamotoYushi en-aut-sei=Nakamoto en-aut-mei=Yushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KojimaSeiya en-aut-sei=Kojima en-aut-mei=Seiya 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=KataokaTakuya en-aut-sei=Kataoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiokaTomohiko en-aut-sei=Yoshioka en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty 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=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=5 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Brookite-type titanium dioxide kn-keyword=Brookite-type titanium dioxide en-keyword=Hydrothermal treatment kn-keyword=Hydrothermal treatment en-keyword=Urea kn-keyword=Urea en-keyword=Sodium chloride kn-keyword=Sodium chloride en-keyword=Apatite-forming ability kn-keyword=Apatite-forming ability END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page= 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=Adaptive Topological Mapping With Free Area-Based Node Deletion for Autonomous Mobile Robots en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes an adaptive topological map building method, called Adaptive Resonance Theory-based Topological Clustering with Different Topologies (ATC-DT), for autonomous mobile robots using 3D point cloud data. ATC-DT framework integrates a novel node deletion mechanism that detects layout changes through free area detection. This allows the robot to update topological maps dynamically, removing outdated nodes caused by environmental changes. Experiments in real environments validate the ability of the method to perform global path planning, free area estimation, and adaptive navigation. The approach significantly improves navigation performance by improving map relevance and reducing redundancy of paths. en-copyright= kn-copyright= en-aut-name=OzakiHaruka en-aut-sei=Ozaki en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TodaYuichiro en-aut-sei=Toda en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuyamaNaoki en-aut-sei=Masuyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiKai en-aut-sei=Fuji en-aut-mei=Kai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsunoTakayuki en-aut-sei=Matsuno en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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 Informatics, Osaka Metropolitan 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= en-keyword=Topological map building kn-keyword=Topological map building en-keyword=navigation system kn-keyword=navigation system en-keyword=autonomous mobile robot kn-keyword=autonomous mobile robot END start-ver=1.4 cd-journal=joma no-vol=194 cd-vols= no-issue= article-no= start-page=50 end-page=62 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=Increasing visual uncertainty modulates multisensory decision-making en-subtitle= kn-subtitle= en-abstract= kn-abstract=The brain integrates and transforms information from multiple senses to make optimal decisions, a process that is critical for navigating complex environments with perceptual uncertainty. Despite a growing consensus that individuals adapt flexibly to uncertain sensory input, whether increasing visual uncertainty influences the decision process itself or other, non-decision sensory processes during multisensory decision-making are unclear. Here, an audiovisual categorization task was used to examine the responses of human participants (N = 30) to visual and audiovisual stimuli under low-, medium-, and high-uncertainty conditions. Modeling the behavioral data using a drift‒diffusion model indicated that increased visual uncertainty in the audiovisual context decreased the evidence accumulation rate but had no effect on non-decision processes. Electrophysiological recordings confirmed and expanded upon these results: increased visual uncertainty in the audiovisual context reduced the amplitude during the late decision-making stage (300–380 msec) but had no effect on the amplitude during the early sensory encoding stage (140–220 msec). More importantly, electroencephalography analyses revealed that audiovisual integration in the early sensory encoding stage occurred robustly across all visual uncertainty conditions, whereas audiovisual integration in the late stage occurred only under medium and high visual uncertainty conditions. This study demonstrated that increased visual uncertainty modulates the decision process itself rather than early sensory encoding during multisensory decision-making. Moreover, multisensory integration strategies dynamically adapt to increasing visual uncertainty by engaging different mechanisms to maintain effective decision-making. en-copyright= kn-copyright= en-aut-name=YangXiangfu en-aut-sei=Yang en-aut-mei=Xiangfu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YangWeiping en-aut-sei=Yang en-aut-mei=Weiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EjimaYoshimichi en-aut-sei=Ejima en-aut-mei=Yoshimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Psychology, Faculty of Education, Hubei 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= en-keyword=Multisensory decision-making kn-keyword=Multisensory decision-making en-keyword=Visual uncertainty kn-keyword=Visual uncertainty en-keyword=Audiovisual integration kn-keyword=Audiovisual integration en-keyword=Event-related potential kn-keyword=Event-related potential en-keyword=Drift‒diffusion model kn-keyword=Drift‒diffusion model END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=6 article-no= start-page=1392 end-page=1399 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Directed Poisoning Attacks on FRIT in Adaptive Cruise Control en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent advances in connected-vehicle technologies have enabled the large-scale collection of driving data, facilitating the deployment of data-driven control schemes. Although these methods offer advantages by eliminating the need for explicit modeling, they also introduce vulnerabilities due to their reliance on stored data. This study investigates a class of targeted data poisoning attacks on fictitious reference iterative tuning, a widely used data-driven controller tuning approach. We present a method that allows an adversary to influence closed-loop dynamics by manipulating the training data so that the resulting controller behavior matches a maliciously defined reference response. This strategy differs from conventional poisoning attacks, which aim only to the degrade control performance. Instead, it enables deliberate alteration of control characteristics such as overshoot and convergence time. The proposed attack is formulated as a constrained optimization problem under bounded tampering signals. Through a numerical study involving adaptive cruise control with stop functionality, we show that minor data modifications, indistinguishable from sensor noise, can cause significant degradation in control behavior. These findings highlight the need for robust security mechanisms in data-driven control implementation. en-copyright= kn-copyright= en-aut-name=IkezakiTaichi en-aut-sei=Ikezaki en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaKenji en-aut-sei=Sawada en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanekoOsamu en-aut-sei=Kaneko en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate school of Mechanical Engineering, The University of Osaka kn-affil= affil-num=3 en-affil=Graduate School of Informatics and Engineering, The University of Electro-Communications kn-affil= en-keyword=cyberattack kn-keyword=cyberattack en-keyword=data-driven control kn-keyword=data-driven control en-keyword=cruise control kn-keyword=cruise control en-keyword=FRIT kn-keyword=FRIT en-keyword=poisoning attack kn-keyword=poisoning attack END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=11 article-no= start-page=1178 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=Sensory Modality-Dependent Interplay Between Updating and Inhibition Under Increased Working Memory Load: An ERP Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Working memory (WM) performance relies on the coordination of updating and inhibition functions within the central executive system. However, their interaction under varying cognitive loads, particularly across sensory modalities, remains unclear. Methods: This study examined how sensory modality modulates flanker interference under increasing WM loads. Twenty-two participants performed a visual n-back task at three load levels (1-, 2-, and 3-back) while ignoring visual (within-modality) or auditory (cross-modality) flankers. Results: Behaviorally, increased WM load (2- and 3-back) led to reduced accuracy (AC) and prolonged reaction times (RTs) in both conditions. In addition, flanker interference was observed under the 2-back condition in both the visual within-modality (VM) and audiovisual cross-modality (AVM) tasks. However, performance impairment emerged at a lower load (2-back) in the VM condition, whereas in the AVM condition, it only emerged at the highest load (3-back). Significant performance impairment in the AVM condition occurred at higher WM loads, suggesting that greater WM load is required to trigger interference. Event-related potential (ERP) results showed that N200 amplitudes increased significantly for incongruent flankers under the highest WM load (3-back) in the visual within-modality condition, reflecting greater inhibitory demands. In the cross-modality condition, enhanced N200 was not observed across all loads and even reversed at low load (1-back). Moreover, the results also showed that P300 amplitude increased with load in the within-modality condition but decreased in the cross-modality condition. Conclusions: These results demonstrated that the interaction between updating and inhibition is shaped by both WM load and sensory modality, further supporting a sensory modality-specific resource allocation mechanism. The cross-modality configurations may enable more efficient distribution of cognitive resources under high load, reducing interference between concurrent executive demands. en-copyright= kn-copyright= en-aut-name=LuoYuxi en-aut-sei=Luo en-aut-mei=Yuxi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GuoAo en-aut-sei=Guo en-aut-mei=Ao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Psychology, Institute of Education, China West Normal University kn-affil= affil-num=3 en-affil=Faculty of Biomedical Engineering, Shenzhen University of Advanced Technology kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=workingmemory load kn-keyword=workingmemory load en-keyword=attentional resource allocation kn-keyword=attentional resource allocation en-keyword=modality-specific interference kn-keyword=modality-specific interference en-keyword=inhibitory control kn-keyword=inhibitory control en-keyword=executive function kn-keyword=executive function en-keyword=sensory modality kn-keyword=sensory modality END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=1599114 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of visual spatial frequency on audiovisual interaction: an event-related potential study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spatial frequency is a fundamental characteristic of visual signals that modulates the audiovisual integration behavior, but the neural mechanisms underlying spatial frequency are not well established. In the present study, the high temporal resolution of event-related potentials was used to investigate how visual spatial frequency modulates audiovisual integration. A visual orientation discrimination task was used, and the spatial frequency of visual stimuli was manipulated under three conditions. Results showed that the influence of visual spatial frequency on audiovisual integration is a dynamic process. The earliest audiovisual integration occurred over the left temporal-occipital regions in the early sensory stage (60–90 ms) for high spatial frequency conditions but was absent for low and middle spatial frequency conditions. In addition, audiovisual integration over fronto-central regions was delayed as spatial frequency increased (from 230–260 ms to 260–320 ms). The integration effect was also observed over parietal and occipital regions at 350–380 ms, and its strength gradually decreased at higher spatial frequencies. These discrepancies in the temporal and spatial distributions of audiovisual integration imply that the role of spatial frequency varies between early sensory and late cognitive stages. The findings of this study offer the first neural demonstration that spatial frequency modulates audiovisual integration, thus providing a basis for studying complex multisensory integration, especially in semantic and emotional domains. en-copyright= kn-copyright= en-aut-name=WuFengxia en-aut-sei=Wu en-aut-mei=Fengxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RenYanna en-aut-sei=Ren en-aut-mei=Yanna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaoTengfei en-aut-sei=Hao en-aut-mei=Tengfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangJingjing en-aut-sei=Yang en-aut-mei=Jingjing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuQiong en-aut-sei=Wu en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangMeng en-aut-sei=Wang en-aut-mei=Meng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=2 en-affil=Department of Psychology, College of Humanities and Management, Guizhou University of Traditional Chinese Medicine kn-affil= affil-num=3 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=4 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=5 en-affil=Department of Psychology, Suzhou University of Science and Technology kn-affil= affil-num=6 en-affil=Cognitive Neuroscience Laboratory, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= en-keyword=spatial frequency kn-keyword=spatial frequency en-keyword=visual orientation discrimination kn-keyword=visual orientation discrimination en-keyword=audiovisual integration kn-keyword=audiovisual integration en-keyword=early sensory stage kn-keyword=early sensory stage en-keyword=late cognitive stage kn-keyword=late cognitive stage en-keyword=event-related potentials kn-keyword=event-related potentials END start-ver=1.4 cd-journal=joma no-vol=163 cd-vols= no-issue=22 article-no= start-page=224312 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fourier-transform infrared spectroscopy of hydrogen fluoride dimers in solid parahydrogen en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigate the Fourier-transform infrared spectra of hydrogen fluoride dimers in solid parahydrogen, the detailed analysis of which has remained unexplored. We propose a plausible analysis based on concentration dependence, light polarization, annealing, and time evolution. The absorption lines exhibited multiple peaks, with intensity ratios significantly altered by annealing and by time evolution at a constant temperature. The spectral patterns and isotopic effects suggest that the dimers do not rotate freely in solid parahydrogen, while multiple peaks arise from different stable structures, including single and double substitution sites. Unlike in the gas phase and helium droplets, no tunneling splitting was observed. The broad ν1 band suggests that some dimer structures may exhibit axial rotation. Spectral changes due to annealing likely result from site conversion, while observed IR-induced changes indicate preferential dissociation of dimers in double substitution sites. These findings still remain tentative, necessitating further experimental and theoretical studies. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OoeHiroki en-aut-sei=Ooe en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Rikkyo University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=140 cd-vols= no-issue= article-no= start-page=105684 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improvements of lateral penumbra at various depth regions in proton pencil beam scanning with a multileaf collimator: Dose verifications and plan comparisons en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: In scanned proton therapy, the current consensus is that the effective range of the collimator’s contribution to lateral penumbra improvement is up to approximately 150 mm depth. We characterized the penumbra variations for scanned proton beams with or without a new type of multileaf collimator (MLC) under various air gaps, depth, and with or without range shifter (RS).
Methods: Eighty-six uniform dose plans were created (38 RS-negative and 48 RS-positive plans) for nine box targets of 60 × 60 × 54 mm3 at 0–280 mm depths in water. They were created with or without MLC, with 50–300 mm air gaps. The penumbra and average doses of MLC-positive and MLC-negative plans at the organs at risk (OAR) region of each box plan were compared. Besides, several plan doses were validated by measurements with penumbra (with an average of 80–20 % dose point widths for both side profiles) differences and 2D gamma analysis.
Results: The MLC-positive plans reduced the penumbra and mean OAR doses by 1.0–5.1 mm and 3.3–13.5 %, respectively, compared to MLC-negative plans even at >150 mm depths. The penumbra differences in measurements were <±1.5 mm for all plans. The mean gamma scores at 2 %/2 mm were 97.9 ± 2.3 % and 97.4 ± 3.1 % for the MLC-negative and MLC-positive plans, respectively.
Conclusions: The MLC-positive beams improved the penumbra and reduced the OAR dose in every depth region and air gap. We have shown that PBS with MLCs can be useful at more than 150 mm regions, depending on the machine. en-copyright= kn-copyright= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaYushi en-aut-sei=Wakisaka en-aut-mei=Yushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoTakahiro en-aut-sei=Kato en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKeisuke en-aut-sei=Yasui en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoRyohei en-aut-sei=Kato en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IchiharaMasaya en-aut-sei=Ichihara en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomidaMasashi en-aut-sei=Tomida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasakiMotoharu en-aut-sei=Sasaki en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishioTeiji en-aut-sei=Nishio en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiotherapy, Medical Co.

Here, we functionally characterized OsHAK4, a member of the clade IV HAK/KUP/KT transporter subfamily in rice. OsHAK4 was localized to the plasma membrane and exhibited influx transport activity for Na+, but not for K+. Analysis of organ- and growth stage-dependent expression patterns showed that very low expression levels of OsHAK4 were detected at the vegetative growth stage, but its high expression in uppermost node I, peduncle, and rachis was found at the reproductive stage. Immunostaining indicated OsHAK4 localization in the phloem region of node I, peduncle, and rachis. Knockout of OsHAK4 did not affect the growth and Na+ accumulation at the vegetative stage. However, at the reproductive stage, the hak4 mutants accumulated higher Na+ in the peduncle, rachis, husk, and brown rice compared to the wild-type rice. Element imaging revealed higher Na+ accumulation at the phloem region of the peduncle in the mutants. These results indicate that OsHAK4 plays a crucial role in retrieving Na+ from the phloem in the upper nodes, peduncle, and rachis, thereby preventing Na+ distribution to the grains at the reproductive stage of rice. en-copyright= kn-copyright= en-aut-name=CheJing en-aut-sei=Che en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangShao Fei en-aut-sei=Wang en-aut-mei=Shao Fei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=XiaYue en-aut-sei=Xia en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangShun Ying en-aut-sei=Yang en-aut-mei=Shun Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuYan Hua en-aut-sei=Su en-aut-mei=Yan Hua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShenRen Fang en-aut-sei=Shen en-aut-mei=Ren Fang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=4 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=5 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=6 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=7 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=rice kn-keyword=rice en-keyword=Oryza sativa kn-keyword=Oryza sativa en-keyword=salinity kn-keyword=salinity en-keyword=HAK transporter kn-keyword=HAK transporter en-keyword=phloem unloading kn-keyword=phloem unloading en-keyword=node kn-keyword=node END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=1714 end-page=1722 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Osmotic pressure‐induced calcium response states en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osmotic pressure is essential for maintaining cellular homeostasis; however, the mechanisms by which cells sense and respond to acute osmotic stress remain incompletely understood. Here, we applied rapid osmotic pressure stimulation to cultured HEK293T cells and observed dynamic intracellular calcium responses. Acute hypotonic stimulation evoked calcium response patterns, whereas hypertonic and isotonic stress did not elicit similar effects. Mechanistically, these calcium signals originated from the endoplasmic reticulum via ryanodine receptor 2 and propagated to neighboring cells through Connexin 43-mediated gap junctions. These findings reveal a previously unrecognized role for calcium signaling in the acute cellular response to osmotic stress, providing new insights into the mechanisms of intercellular communication during osmotic adaptation. en-copyright= kn-copyright= en-aut-name=GaoZidan en-aut-sei=Gao en-aut-mei=Zidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuMasatoshi en-aut-sei=Morimatsu en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Okayama Japan kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Okayama Japan kn-affil= en-keyword=calcium wave kn-keyword=calcium wave en-keyword=Connexin 43 kn-keyword=Connexin 43 en-keyword=hypotonic pressure kn-keyword=hypotonic pressure en-keyword=osmotic pressure kn-keyword=osmotic pressure en-keyword=ryanodine receptor kn-keyword=ryanodine receptor END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e13537 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Atomic-Level Insights into Thermal Carbonization of Ethynyl-Containing Boron Compounds en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study reports the design, synthesis, and characterization of boron-doped carbon (BDC) derived from a triethynylborane-pyridine complex. Triethynylborane is stabilized by coordination with pyridine, facilitating its synthesis and handling in ambient conditions. The complex is subjected to thermal treatment at various temperatures to form BDC. Powder XRD and single-crystal XRD analyses reveal that BDC prepared at 200 °C retains an ordered structure, while higher temperatures induce alkyne structural changes without significant weight or surface area alterations. Coin cells are assembled using BDC as the anode, demonstrating unique Li-ion and Na-ion storage properties distinct from graphite. These results suggest that the BDC reflects the precursor's crystal structure, enabling novel electrochemical behavior. These findings offer insight into the development of advanced BDC materials for energy storage applications. en-copyright= kn-copyright= en-aut-name=OhkuraKentaro en-aut-sei=Ohkura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayakawaSatoshi en-aut-sei=Hayakawa en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiNaoki en-aut-sei=Takahashi en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanoJun en-aut-sei=Kano en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, 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=Graduate School of Environment Life Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environment Life Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environment Life Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=boron-doped carbon kn-keyword=boron-doped carbon en-keyword=carbonization kn-keyword=carbonization en-keyword=ethynyl group kn-keyword=ethynyl group en-keyword=Li-ion kn-keyword=Li-ion en-keyword=Na-ion kn-keyword=Na-ion END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=ycaf192 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proliferation of a bloom-forming phytoplankton via uptake of polyphosphate-accumulating bacteria under phosphate-limiting conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Harmful algal blooms negatively impact the ecosystem and fisheries in affected areas. Eutrophication is a major factor contributing to bloom occurrence, and phosphorus is particularly important in limiting the growth of bloom-forming algae. Although algae efficiently utilize orthophosphate (Pi) as a phosphorous source over other molecular forms, Pi is often limited in the marine environment. While uptake and utilization of soluble inorganic and organic phosphorous by bloom-forming algae has been extensively studied, the details of geochemical and biological phosphorous cycling remain to be elucidated. Here, we report for the first time that the bloom-forming alga Heterosigma akashiwo can phagocytose bacteria and grow under phosphate-depleted conditions. The addition of Vibrio comitans to Pi-depleted H. akashiwo enabled the alga propagate to high cell densities, whereas other bacterial strains had only a minor effect. Importantly, V. comitans accumulates polyphosphate—a linear polymer of Pi—at high levels. The extent of algal proliferation induced by the addition of Vibrio species and polyphosphate-accumulating Escherichia coli correlated strongly with their polyphosphate content, indicating that bacterial polyphosphate served as an alternative PO43− source for H. akashiwo. The direct uptake of polyphosphate-accumulating bacteria through algal phagocytosis may represent a novel biological phosphorous-cycling pathway in marine ecosystems. The role of polyphosphate-accumulating marine bacteria as a hidden phosphorous source required for bloom formation warrants further investigation. en-copyright= kn-copyright= en-aut-name=FukuyamaSeiya en-aut-sei=Fukuyama en-aut-mei=Seiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UsamiFumiko en-aut-sei=Usami en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirotaRyuichi en-aut-sei=Hirota en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OharaShizuka en-aut-sei=Ohara en-aut-mei=Shizuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KondoKen en-aut-sei=Kondo en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GomibuchiYuki en-aut-sei=Gomibuchi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasunagaTakuo en-aut-sei=Yasunaga en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OndukaToshimitsu en-aut-sei=Onduka en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KurodaAkio en-aut-sei=Kuroda en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoikeKazuhiko en-aut-sei=Koike en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=UekiShoko en-aut-sei=Ueki en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=Graduate School of Integrated Sciences for Life, Hiroshima 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 Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=6 en-affil=Research Institute of Environment, Agriculture and Fisheries , Osaka Prefecture kn-affil= affil-num=7 en-affil=Department of Physics and Information Technology, Faculty of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=8 en-affil=Department of Physics and Information Technology, Faculty of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=9 en-affil=Hatsukaichi Branch, Fisheries Technology Institute , Fisheries Research and Education Agency kn-affil= affil-num=10 en-affil=Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=11 en-affil=Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=12 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A rare case of supratentorial ependymosarcoma harboring ZFTA::RELA fusion en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ependymosarcoma is an exceedingly rare variant of ependymoma characterized by a mixture of ependymomatous and sarcomatous components. We report a case of supratentorial ependymosarcoma harboring a ZFTA::RELA fusion in a 10-year-old girl. Histologically, the tumor comprised an ependymomatous component resembling clear cell ependymoma and a sarcomatous component. ZFTA::RELA fusion was confirmed in both components. Genome-wide methylation profiling classified both components as supratentorial ependymoma, ZFTA fusion–positive by the German Cancer Research Center (DKFZ) CNS tumor classifier v12b8. However, their copy number alteration profiles were distinct. The ependymomatous component exhibited a gain of chromosome 1q and a loss of chromosomes 1p, 9, and 19q, while the sarcomatous component showed a loss of chromosome 14. These findings suggest that both components may have differentiated from a common precursor despite their distinct morphologies. The patient underwent gross total resection followed by adjuvant chemoradiotherapy and remains recurrence-free eight years post-treatment. Further investigation of additional cases is warranted to better understand the pathogenesis of this rare tumor. en-copyright= kn-copyright= en-aut-name=MatsumotoYuji en-aut-sei=Matsumoto

kn-subject= en-title= kn-title=Clinical predictors of extubation failure in postoperative critically ill patients: a post-hoc analysis of a multicenter prospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Postoperative patients constitute majority of critically ill patients, although factors predicting extubation failure in this group of patients remain unidentified. Aiming to propose clinical predictors of reintubation in postoperative patients, we conducted a post-hoc analysis of a multicenter prospective observational study.
Methods This study included postoperative critically ill patients who underwent mechanical ventilation for > 24 h and were extubated after a successful 30-min spontaneous breathing trial. The primary outcome was reintubation within 48 h after extubation, and clinical predictors for reintubation were investigated using logistic regression analyses.
Results Among the 355 included patients, 10.7% required reintubation. Multivariable logistic regression identified that the number of endotracheal suctioning episodes during the 24 h before extubation and underlying respiratory disease or pneumonia occurrence were significantly associated with reintubation (adjusted odds ratio [OR] 1.11, 95% confidence interval [CI] 1.05–1.18, p < 0.001; adjusted OR 2.58, 95%CI 1.30–5.13, p = 0.007). The probability of reintubation was increased significantly with the higher frequency of endotracheal suctioning, as indicated by restricted cubic splines. Subgroup analysis showed that these predictors were consistently associated with reintubation regardless of the use of noninvasive respiratory support after extubation.
Conclusions Endotracheal suctioning frequency and respiratory complications were identified as independent predictors of reintubation. These readily obtainable predictors may aid in decision-making regarding the extubation of postoperative patients. en-copyright= kn-copyright= en-aut-name=HattoriJun en-aut-sei=Hattori en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAiko en-aut-sei=Tanaka en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakaJunko en-aut-sei=Kosaka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraoOsamu en-aut-sei=Hirao en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FurushimaNana en-aut-sei=Furushima en-aut-mei=Nana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MakiYuichi en-aut-sei=Maki en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KabataDaijiro en-aut-sei=Kabata en-aut-mei=Daijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchiyamaAkinori en-aut-sei=Uchiyama en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EgiMoritoki en-aut-sei=Egi en-aut-mei=Moritoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MizobuchiSatoshi en-aut-sei=Mizobuchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KotakeYoshifumi en-aut-sei=Kotake en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ShintaniAyumi en-aut-sei=Shintani en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KoyamaYukiko en-aut-sei=Koyama en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshidaTakeshi en-aut-sei=Yoshida en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=FujinoYuji en-aut-sei=Fujino en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Faculty of Medicine, Osaka University kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology, Osaka General Medical Center kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Intensive Care Medicine, Kobe University Hospital kn-affil= affil-num=6 en-affil=Department of Anesthesiology, Toho University Ohashi Medical Center kn-affil= affil-num=7 en-affil=Center for Mathematical and Data Science, Kobe University kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Anesthesia, Kyoto University Hospital kn-affil= affil-num=10 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Anesthesiology and Intensive Care Medicine, Kobe University Hospital kn-affil= affil-num=12 en-affil=Department of Anesthesiology, Toho University Ohashi Medical Center kn-affil= affil-num=13 en-affil=Department of Medical Statistics, Graduate School of Medicine, Osaka Metropolitan University kn-affil= affil-num=14 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=15 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=16 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= en-keyword=Reintubation kn-keyword=Reintubation en-keyword=Extubation failure kn-keyword=Extubation failure en-keyword=Endotracheal suctioning kn-keyword=Endotracheal suctioning en-keyword=Postoperative patient kn-keyword=Postoperative patient en-keyword=Clinical predictor kn-keyword=Clinical predictor en-keyword=Critical care kn-keyword=Critical care END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=9916 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A node-localized efflux transporter for loading iron to developing tissues in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Iron (Fe) is an essential micronutrient for plant growth and development. It plays crucial roles in various organs and tissues of plants, but the molecular mechanisms governing its distribution to the above-ground parts after root uptake remain unclear. In this study, we identify OsIET1 (Oryza sativa Iron Efflux Transporter 1), a rice gene highly expressed in the nodes. OsIET1 encodes a plasma membrane-localized protein, which shows efflux transport activity for ferrous iron. It is predominantly expressed in the xylem regions of diffuse vascular bundles, and its expression is upregulated under high Fe conditions. Disruption of OsIET1 impairs Fe allocation, reducing Fe transport to developing tissues (young leaves and grains), while increasing accumulation in nodes and older leaves. This misdistribution causes chlorosis in young leaves and decreases grain yield, especially under Fe-deficient conditions. Furthermore, we detect excessive Fe deposition around the xylem of diffuse vascular bundles in the nodes. Given the pivotal role of nodes in mineral distribution, our results indicate that OsIET1 mediates inter-vascular Fe transfer by facilitating Fe loading into the xylem of diffuse vascular bundles. This process ensures preferential Fe delivery to developing tissues, thereby promoting optimal plant growth and productivity. en-copyright= kn-copyright= en-aut-name=CheJing en-aut-sei=Che en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=QuYuting en-aut-sei=Qu en-aut-mei=Yuting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiokaYuma en-aut-sei=Yoshioka en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomitaChiyuri en-aut-sei=Tomita en-aut-mei=Chiyuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiuZhenyang en-aut-sei=Liu en-aut-mei=Zhenyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShenRenfang en-aut-sei=Shen en-aut-mei=Renfang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=State Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=State Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=8 en-affil=State Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=27 article-no= start-page=6557 end-page=6563 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=Fluorescence detection of DNA with a single-base mismatch by a Tm-independent peptide nucleic acid (PNA) twin probe en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is a need to develop efficient methods for detecting target nucleic acids to enable the rapid diagnosis and early treatment of diseases. We previously demonstrated that a peptide nucleic acid (PNA) twin probe, consisting of two PNAs each containing a fluorescent dye, with pyrene at one end, detects target DNA sequence-specifically through pyrene excimer emission. In this study, to advance the development of this probe system, we further investigated the fluorescence properties of the PNA twin probe P1 and P2, and found that the excimer fluorescence was significantly reduced when a mismatched base in the DNA sequence was present at the site of P1 closest to the pyrene. In other words, this probe was found to detect single-base mismatches without taking into account the thermal stability of the PNA/DNA hybrid. The detection limit of this PNA twin probe for the single-base-mismatched DNA was 2.7 nM. In the future, this probe should lead to a method to detect point mutations in endogenous nucleic acids within cells. en-copyright= kn-copyright= en-aut-name=IshiiKoki en-aut-sei=Ishii en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigetoHajime en-aut-sei=Shigeto en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamuraShohei en-aut-sei=Yamamura en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImaiYoshitane en-aut-sei=Imai en-aut-mei=Yoshitane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=2 en-affil=Health and Medical Research Institute, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=3 en-affil=Health and Medical Research Institute, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry, Kindai University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250923 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=INF2-Related Charcot–Marie–Tooth Disease in a Japanese Cohort: Genetic and Clinical Insights en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: INF2 mutations cause focal segmental glomerulosclerosis (FSGS) and Charcot–Marie–Tooth disease (CMT). Accurate genetic diagnosis is critical, as INF2-related FSGS is typically resistant to immunotherapy yet rarely recurs after transplantation, and its associated neuropathy can mimic treatable immune-mediated disorders such as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP).
Methods: We performed a multicenter study investigating 3329 Japanese patients with inherited peripheral neuropathies/CMT who underwent gene panel sequencing or whole-exome analysis between 2007 and 2024. Clinical data, including electrophysiological assessments, were obtained from the patients' medical records.
Results: We identified six pathogenic INF2 variants in eight patients, all of which were located within the diaphanous inhibitory domain. Structural modeling revealed clustering of variants near the diaphanous autoregulatory domain-binding pocket, which is critical for INF2 autoinhibition. Clinically, all cases were sporadic, with a median age at neurological onset of 9 years. All patients exhibited lower limb weakness, and 6/8 (75%) had sensory disturbances. All patients also developed kidney dysfunction, with 7/8 (88%) progressing to end-stage renal disease at a median age of 15 years. Furthermore, all patients showed demyelinating neuropathy, and 2/8 (25%) received immunotherapy due to suspected immune-mediated neuropathy.
Conclusion: Although INF2 variants are a rare cause of CMT in Japan, they should be considered in pediatric patients with demyelinating neuropathy and early-onset proteinuria, even in the absence of a family history. Blood and urine tests assessing renal dysfunction can provide guidance for appropriate genetic testing. en-copyright= kn-copyright= en-aut-name=YanoChikashi en-aut-sei=Yano en-aut-mei=Chikashi

However, there are issues such as lower strength than annealed α+β structure and decreasing damping capacity due to heating until 400 K. Therefore, in this study, to address these issues, we investigated the effect of Al addition on the constituent phases and material properties of Ti-18Nb-xAl alloys. The crystal structure was determined by examining the lattice constant and unit volume using X-ray diffraction, and optical microscopy was also performed. The material properties were investigated by Vickers hardness, Young’s modulus, internal friction, tensile tests, and DSC measurements. Vickers hardness and tensile strength increased with increasing Al content. This is thought to be due to the combined effects of the refinement of the microstructure and solid-solution strengthening due to Al addition. The Young’s modulus increased slightly from 0Al to 1Al, but increased significantly to 4Al. Internal friction was highest for 0Al and decreased for 4Al, whereas 7Al showed a higher value than 1Al. In the DSC heating curves, there was a decrease in the exothermic peak starting temperature and an increase in the phase-transformation heat with the addition of Al, except for 1Al. It was suggested that these changes in Ti-18Nb-xAl alloys were influenced by the structure of the quenched α” phase, texture, and pseudoelasticity or phase transformation by deformation. en-copyright= kn-copyright= en-aut-name=MantaniYoshikazu en-aut-sei=Mantani en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoYoshito en-aut-sei=Takemoto en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Materials Science and Engineering, National Institute of Technology (KOSEN), Suzuka College kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=ternary titanium alloy kn-keyword=ternary titanium alloy en-keyword=martensite kn-keyword=martensite en-keyword=lattice constant kn-keyword=lattice constant en-keyword=hardness kn-keyword=hardness en-keyword=Young’s modulus kn-keyword=Young’s modulus en-keyword=internal friction kn-keyword=internal friction en-keyword=cyclic tensile test kn-keyword=cyclic tensile test en-keyword=texture kn-keyword=texture END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue= article-no= start-page= 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=岡山大学環境管理センター報　第47号 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学安全衛生推進機構環境管理部門 kn-aut-sei=岡山大学安全衛生推進機構環境管理部門 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250811 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=RNA Delivery Using a Graphene Oxide-Polyethylenimine Hybrid Inhibiting Myotube Differentiation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Graphene oxide (GO) conjugated with short polyethylenimine (PEI) chains (GO-PEI) has been designed as a candidate nanocarrier for small interfering RNA (siRNA) delivery to mammalian cells based on the efficient interaction between the positively charged GO-based platform and the negatively charged siRNA. The function and efficiency of siRNA delivery using GO-PEI were compared to those using the positive control Lipofectamine RNAiMax by analyzing the differentiation to myotubes, and myogenin gene and protein expression in C2C12 cells. RNAiMax transfection induced cellularization and reduction of both myogenin gene and protein expression, suggesting that the differentiation of C2C12 cells was triggered by gene silencing. While GO-PEI also promoted cellularization, the myogenin gene expression remained comparable to scrambled controls, whereas the protein levels were higher than those observed with RNAiMax. Mechanistically, we attributed the reduced gene silencing efficiency of GO-PEI to a poor endosomal escape, despite strong siRNA complexation. This limitation was likely due to a low buffering capacity of GO-PEI, as a significant fraction of nitrogen atoms were already protonated, reducing the availability of free amines necessary for endosomal disruption. An appropriate chemical modification to enhance siRNA release from the endosomes is therefore essential for advancing the development of GO-based platforms as versatile and efficient nanocarriers in gene therapy applications. en-copyright= kn-copyright= en-aut-name=MatsuuraKoji en-aut-sei=Matsuura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ReinaGiacomo en-aut-sei=Reina en-aut-mei=Giacomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GaoZhengfeng en-aut-sei=Gao en-aut-mei=Zhengfeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=CNRS, Immunology, Immunopathology and Therapeutic Chemistry, UPR3572, University of Strasbourg, ISIS kn-affil= affil-num=2 en-affil=CNRS, Immunology, Immunopathology and Therapeutic Chemistry, UPR3572, University of Strasbourg, ISIS kn-affil= affil-num=3 en-affil=CNRS, Immunology, Immunopathology and Therapeutic Chemistry, UPR3572, University of Strasbourg, ISIS kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=CNRS, Immunology, Immunopathology and Therapeutic Chemistry, UPR3572, University of Strasbourg, ISIS kn-affil= en-keyword=graphene oxide kn-keyword=graphene oxide en-keyword=polyethylenimine kn-keyword=polyethylenimine en-keyword=myotubes kn-keyword=myotubes en-keyword=myogenin kn-keyword=myogenin en-keyword=small interfering RNA kn-keyword=small interfering RNA en-keyword=transfection kn-keyword=transfection END start-ver=1.4 cd-journal=joma no-vol=133 cd-vols= no-issue=9 article-no= start-page=555 end-page=561 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=Preparation and structural characterization of nanoporous silica/magnesium(II)-whitlockite composite particles en-subtitle= kn-subtitle= en-abstract= kn-abstract=The preparation of particles composed of nanoporous silica (NS) and Mg2+-whitlockite (Mg-WH) would provide valuable insights for designing particles for biomedical applications.

The addition of chitosan during synthesis possibly promoted the crystallization of calcium phosphate phases in the composite particles. Pore size distribution analysis of the particles showed a maximum at 3.2 nm. Investigating the adsorption of methylene blue onto the particles in a phosphate buffer (pH 7.4) showed that the saturated adsorption amount of methylene blue on the particles was significantly higher than that on commercial hydroxyapatite. The composite particles provided important results for potential applications as drug carriers for bone regeneration and repair. en-copyright= kn-copyright= en-aut-name=KataokaTakuya en-aut-sei=Kataoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirotaDaiki en-aut-sei=Hirota en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiEiji en-aut-sei=Fujii en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiokaTomohiko en-aut-sei=Yoshioka en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayakawaSatoshi en-aut-sei=Hayakawa en-aut-mei=Satoshi 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=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Industrial Technology Center of Okayama Prefecture 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= en-keyword=Nanoporous silica kn-keyword=Nanoporous silica en-keyword=Magnesium(II)-whitlockite kn-keyword=Magnesium(II)-whitlockite en-keyword=Composite particle kn-keyword=Composite particle en-keyword=Drug carriers for bone regeneration and repair kn-keyword=Drug carriers for bone regeneration and repair END start-ver=1.4 cd-journal=joma no-vol=133 cd-vols= no-issue=1 article-no= start-page=15 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative study of the effects of fluoride treatment with cyclic variations in pH on the structures of stoichiometric, calcium-deficient, and carbonated hydroxyapatites en-subtitle= kn-subtitle= en-abstract= kn-abstract=The primary objective of this study was to analyze the effects of fluoride treatment with cyclic variations in pH on the structure of stoichiometric hydroxyapatite (HAp), calcium-deficient HAp (CDHAp), and carbonated HAp (CHAp) powders. The structures of HAp, CDHAp, and CHAp before and after fluoride treatment were investigated using X-ray diffraction, Fourier-transform infrared, Raman, and nuclear magnetic resonance spectroscopic analyses. The fluoride treatment with cyclic variations in pH increased the calcium deficiency in HAp and CHAp but decreased in CDHAp. During fluoride treatment, fluoridated CDHAp or fluoridated calcium-deficient CHAp was formed on the surface of the HAp samples via dissolution and crystal growth, accompanied by the selective elution of component ions and partial substitution of OH− groups in the HAp hexagonal lattice with F− ions. No evidence of the formation of Ca(OH)2 and OH− groups outside the HAp crystal lattice was obtained. A new perspective on the formation of structured water at the surface termination of the OH columns (disordered region), with possible interactions with adsorbed water molecules or nonspecifically adsorbed F− ions was provided. The top surface of the fluoridated CDHAp consisted of an amorphous fluoride-rich hydrated layer, which included calcium phosphate and CaF2. en-copyright= kn-copyright= en-aut-name=HayakawaSatoshi en-aut-sei=Hayakawa en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaYu en-aut-sei=Okada en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshiokaTomohiko en-aut-sei=Yoshioka en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Hydroxyapatite kn-keyword=Hydroxyapatite en-keyword=Fluoride treatment kn-keyword=Fluoride treatment en-keyword=Microstructure kn-keyword=Microstructure en-keyword=Calcium fluoride kn-keyword=Calcium fluoride en-keyword=Structured water kn-keyword=Structured water END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=9 article-no= start-page=1135 end-page=1151 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Heart failure-specific cardiac fibroblasts contribute to cardiac dysfunction via the MYC–CXCL1–CXCR2 axis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heart failure (HF) is a growing global health issue. While most studies focus on cardiomyocytes, here we highlight the role of cardiac fibroblasts (CFs) in HF. Single-cell RNA sequencing of mouse hearts under pressure overload identified six CF subclusters, with one specific to the HF stage. This HF-specific CF population highly expresses the transcription factor Myc. Deleting Myc in CFs improves cardiac function without reducing fibrosis. MYC directly regulates the expression of the chemokine CXCL1, which is elevated in HF-specific CFs and downregulated in Myc-deficient CFs. The CXCL1 receptor, CXCR2, is expressed in cardiomyocytes, and blocking the CXCL1–CXCR2 axis mitigates HF. CXCL1 impairs contractility in neonatal rat and human iPSC-derived cardiomyocytes. Human CFs from failing hearts also express MYC and CXCL1, unlike those from controls. These findings reveal that HF-specific CFs contribute to HF via the MYC–CXCL1–CXCR2 pathway, offering a promising therapeutic target beyond cardiomyocytes. en-copyright= kn-copyright=

kn-subtitle= en-abstract= kn-abstract=Increased drug metabolism and elimination are prominent mechanisms mediating multidrug resistance (MDR) to not only chemotherapy drugs but also anti-cancer natural products, such as benzyl isothiocyanate (BITC). To evaluate the possibility of combined utilization of a certain compound to overcome this resistance, we focused on glutathione S-transferase (GST)-dependent metabolism of BITC. The pharmacological treatment of a pi-class GST-selective inhibitor, 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol (NBDHEX), significantly increased BITC-induced toxicity in human colorectal cancer HCT-116 cells. However, NBDHEX unexpectedly increased the level of the BITC–glutathione (GSH) conjugate as well as BITC-modified proteins, suggesting that NBDHEX might increase BITC-modified protein accumulation by inhibiting BITC–GSH excretion instead of inhibiting GST. Furthermore, NBDHEX significantly potentiated BITC-induced apoptosis with the enhanced activation of apoptosis-related pathways, such as c-Jun N-terminal kinase and caspase-3 pathways. These results suggested that combination treatment with NBDHEX may be an effective way to overcome MDR with drug efflux and thus induce the biological activity of BITC at lower doses. en-copyright= kn-copyright= en-aut-name=SunRuitong en-aut-sei=Sun en-aut-mei=Ruitong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoAina en-aut-sei=Yano en-aut-mei=Aina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=benzyl isothiocyanate kn-keyword=benzyl isothiocyanate en-keyword=multidrug resistance kn-keyword=multidrug resistance en-keyword=glutathione S-transferase kn-keyword=glutathione S-transferase en-keyword=NBDHEX kn-keyword=NBDHEX en-keyword=apoptosis kn-keyword=apoptosis en-keyword=c-Jun N-terminal kinase kn-keyword=c-Jun N-terminal kinase END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=7 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Animal–chlorophyte photosymbioses: evolutionary origins and ecological diversity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic symbiosis occurs across diverse animal lineages, including Porifera, Cnidaria, Xenacoelomorpha and Mollusca. These associations between animal hosts and photosynthetic algae often involve the exchange of essential macronutrients, supporting adaptation to a wide range of aquatic environments. A small yet taxonomically widespread subset of animals host photosymbionts from the core chlorophytes, a phylogenetically expansive clade of green algae. These rare instances of ‘plant-like’ animals have arisen independently across distantly related lineages, resulting in striking ecological and physiological diversity. Although such associations provide valuable insights into the evolution of symbiosis and adaptation to novel ecological niches, animal–chlorophyte photosymbioses remain relatively understudied. Here, we present an overview of photosymbioses between animals and chlorophytes, highlighting their independent evolutionary origins, ecological diversity and emerging genomic resources. Focusing on Porifera, Cnidaria and Xenacoelomorpha, we review shared and lineage-specific adaptations underlying these associations. We also contrast them with dinoflagellate-based systems to demonstrate their distinct ecological and cellular features. Our work sets the stage for elucidating the molecular mechanisms underlying these associations, enhancing our understanding of how interspecies interactions drive adaptation to unique ecological niches through animal–chlorophyte symbiosis. en-copyright= kn-copyright= en-aut-name=LiaoIsabel Jiah-Yih en-aut-sei=Liao en-aut-mei=Isabel Jiah-Yih kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakagamiTosuke en-aut-sei=Sakagami en-aut-mei=Tosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LewinThomas D. en-aut-sei=Lewin en-aut-mei=Thomas D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BaillyXavier en-aut-sei=Bailly en-aut-mei=Xavier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=LuoYi-Jyun en-aut-sei=Luo en-aut-mei=Yi-Jyun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Biodiversity Research Center, Academia Sinica kn-affil= affil-num=2 en-affil=Biodiversity Research Center, Academia Sinica kn-affil= affil-num=3 en-affil=Biodiversity Research Center, Academia Sinica kn-affil= affil-num=4 en-affil=Laboratoire des Modèles Marins Multicellulaires, Station Biologique de Roscoff kn-affil= affil-num=5 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=6 en-affil=Biodiversity Research Center, Academia Sinica kn-affil= en-keyword=hydra kn-keyword=hydra en-keyword=photosymbiosis kn-keyword=photosymbiosis en-keyword=green algae kn-keyword=green algae en-keyword=acoels kn-keyword=acoels en-keyword=sponges kn-keyword=sponges END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=2 article-no= start-page=80 end-page=81 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Anatomy-Physiology-Pharmacology Week in 2025 kn-title=第130回日本解剖学会／第102回日本生理学会／第98回日本薬理学会合同大会 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name=成瀬恵治 kn-aut-sei=成瀬 kn-aut-mei=恵治 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域　システム生理学 END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=9 article-no= start-page=4310 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Possibility of Plasma Membrane Transporters as Drug Targets in Oral Cancers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plasma membrane transporters are increasingly recognized as potential drug targets for oral cancer, particularly oral squamous cell carcinoma (OSCC). These transporters play crucial roles in cancer cell metabolism, drug resistance, and the tumor microenvironment, making them attractive targets for therapeutic intervention. Among the two main families of plasma membrane transporters, ATP-binding cassette (ABC) transporters have long been known to be involved in drug efflux and contribute to chemoresistance in cancer cells. On the other hand, solute carriers (SLCs) are also a family of transporters that facilitate the transport of various substrates, including nutrients and drugs, and have recently been shown to contribute to cancer chemosensitivity, metabolism, and proliferation. SLC transporters have been identified as potential cancer biomarkers and therapeutic targets, and their expression profiles suggest that they could be utilized in precision oncology approaches. We summarize previous reports on the expression and role of ABC and SLC transporters in oral cancer and discuss their potential as therapeutic targets. en-copyright= kn-copyright= en-aut-name=SogawaChiharu en-aut-sei=Sogawa en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimadaKatsumitsu en-aut-sei=Shimada en-aut-mei=Katsumitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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= affil-num=1 en-affil=Department of Food and Health Sciences, Faculty of Environmental Studies, Hiroshima Institute of Technology kn-affil= affil-num=2 en-affil=Department of Clinical Phathophysiology, Matsumoto Dental 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= en-keyword=SLC transporter kn-keyword=SLC transporter en-keyword=ABC transporter kn-keyword=ABC transporter en-keyword=oral cancer kn-keyword=oral cancer en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma END start-ver=1.4 cd-journal=joma no-vol=189 cd-vols= no-issue= article-no= start-page=87 end-page=100 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Designing a Lesson Plan Ensuring “Sense of Involvement” in Controversial Issue Learning: Based on the Development of a Learning Unit “Thinking Our Society through Conflict Minerals” in the Subject “Modern and Contemporary History” in the Geography and History kn-title=論争問題学習における「当事者性」を保障する授業設計 ―地理歴史科「歴史総合」小単元「紛争鉱物から考える私たちの社会」の開発を事例として― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　社会問題についての熟議や意思決定，合意形成には当事者性が必要である。当事者性がなければ，皆が納得する答え，すなわち公共善を構築することはできない。しかし，当事者性を強調することがかえって生徒の「思考停止」を導くという批判もあり，当事者性を保障する以前に、当事者性そのものの概念を再考する必要がある。 　そこで，本研究では，「思考停止」に至らない当事者性とはどのようなものか，先行研究をもとに再定義を行う。その定義を踏まえて、学習者に「当事者性」を保障する授業構成のあり方を考察し，地理歴史科「歴史総合」の小単元「紛争鉱物から考えるグローバル社会」の開発を行う。 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=KAMITAMichiko en-aut-sei=KAMITA en-aut-mei=Michiko kn-aut-name=紙田路子 kn-aut-sei=紙田 kn-aut-mei=路子 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=Department of Primary Education, Faculty of Education, Okayama University of Science kn-affil=岡山大学理科大学教育学部 en-keyword=当事者性 kn-keyword=当事者性 en-keyword=論争問題学習 kn-keyword=論争問題学習 en-keyword=歴史総合 kn-keyword=歴史総合 en-keyword=地理歴史科 kn-keyword=地理歴史科 END start-ver=1.4 cd-journal=joma no-vol=189 cd-vols= no-issue= article-no= start-page=67 end-page=74 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Educational Support Based on an Understanding of the Pathology of Spina Bifida kn-title=二分脊椎症の病態理解に基づく教育現場での支援 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　二分脊椎症のある子どもは、症状の個人差が大きく、肢体不自由特別支援学校だけでなく普通学級にも多く在籍している。本研究の目的は，二分脊椎症の病態に基づき、教育現場での支援の在り方について、先行研究の知見をまとめ、教育上の課題をあきらかにすることである。

To generate a pushing force, the circumferential stiffness of an extension-type flexible soft actuator must be reinforced. Therefore, a cross-linked EFPA (CL-EFPA) was developed, inspired by a pantograph that restrains the EFPA three-dimensionally using the proposed link mechanism. The proposed CL-EFPA consists of three EFPAs and a cross-linking mechanism for integrating each EFPA circumference. The pushing force of the CL-EFPA is approximately 3.0 times compared with that generated by the previous EFPA with plates to restrain its plane. To perform various bending motions, attitude control was performed using an analytical model and a system that included valves, sensors, and controllers. en-copyright= kn-copyright= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TadachiKazuma en-aut-sei=Tadachi en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Mechanical and Systems Engineering Program, School of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Soft robot kn-keyword=Soft robot en-keyword=Extension soft actuator kn-keyword=Extension soft actuator en-keyword=Link mechanism kn-keyword=Link mechanism en-keyword=Pantograph kn-keyword=Pantograph en-keyword=Attitude control kn-keyword=Attitude control END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=1 article-no= start-page=43 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fan-Shaped Pneumatic Soft Actuator that Can Operate Bending Motion for Ankle-Joint Rehabilitation Device en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, owing to declining birthrates and an aging population, patients and the elderly requiring rehabilitation are not getting enough physical activity. In addressing this issue, devices for rehabilitating them have been researched and developed. However, rehabilitation devices are almost exclusively used for patients who can get up, rather than those who are bedridden. In this study, we aim to develop a rehabilitation device that can provide passive exercise for bedridden patients. The ankle joint was selected as the target joint because the patients who have undergone surgery for cerebrovascular disease remain bedridden, and early recovery in the acute stage is highly desirable. We proposed and tested a fan-shaped pneumatic soft actuator (FPSA) that can expand and bend stably at angles when supply pressure is applied as an actuator for a rehabilitation device to encourage patient exercise. However, the previous FPSA’s movement deviates from the arch of the foot owing to increased supply pressure. In the ideal case, FPSA should push the arch of the foot in an arc motion. This study proposes and tests the FPSA that can operate a bending motion to provide passive exercise to the ankle joint using tensile springs and a winding mechanism powered by a servo motor. The proposed FPSA has a significant advantage of exhibiting no hysteresis in its pressure-displacement characteristics. The configuration and static analytical model of the improved FPSA are described. en-copyright= kn-copyright= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyaHirosato en-aut-sei=Yokoya en-aut-mei=Hirosato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShiomiShun en-aut-sei=Shiomi en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeharaTakenori en-aut-sei=Uehara en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirayamaTakahiro en-aut-sei=Hirayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, 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=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, NHO Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=fan-shaped pneumatic soft actuator kn-keyword=fan-shaped pneumatic soft actuator en-keyword=ankle-joint rehabilitation device kn-keyword=ankle-joint rehabilitation device en-keyword=hysteresis kn-keyword=hysteresis en-keyword=range of motion kn-keyword=range of motion END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=606 end-page=617 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mechanistic Insights Into Oxidative Response of Heat Shock Factor 1 Condensates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heat shock factor 1 (Hsf1), a hub protein in the stress response and cell fate decisions, senses the strength, type, and duration of stress to balance cell survival and death through an unknown mechanism. Recently, changes in the physical property of Hsf1 condensates due to persistent stress have been suggested to trigger apoptosis, highlighting the importance of biological phase separation and transition in cell fate decisions. In this study, the mechanism underlying Hsf1 droplet formation and oxidative response was investigated through 3D refractive index imaging of the internal architecture, corroborated by molecular dynamics simulations and biophysical/biochemical experiments. We found that, in response to oxidative conditions, Hsf1 formed liquid condensates that suppressed its internal mobility. Furthermore, these conditions triggered the hyper-oligomerization of Hsf1, mediated by disulfide bonds and secondary structure stabilization, leading to the formation of dense core particles in the Hsf1 droplet. Collectively, these data demonstrate how the physical property of Hsf1 condensates undergoes an oxidative transition by sensing redox conditions to potentially drive cell fate decisions. en-copyright= kn-copyright= en-aut-name=KawagoeSoichiro en-aut-sei=Kawagoe en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsusakiMotonori en-aut-sei=Matsusaki en-aut-mei=Motonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MabuchiTakuya en-aut-sei=Mabuchi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgasawaraYuto en-aut-sei=Ogasawara en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshimoriKoichiro en-aut-sei=Ishimori en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaioTomohide en-aut-sei=Saio en-aut-mei=Tomohide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=2 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Frontier Research Institute for Interdisciplinary Sciences, Tohoku University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Chemistry, Faculty of Science, Hokkaido University kn-affil= affil-num=7 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= en-keyword=heat shock factor 1 kn-keyword=heat shock factor 1 en-keyword=oxidative hyper-oligomerization kn-keyword=oxidative hyper-oligomerization en-keyword=biological phase transition kn-keyword=biological phase transition en-keyword=stress response kn-keyword=stress response en-keyword=biophysics kn-keyword=biophysics END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=8 article-no= start-page=e18026 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=Commissioning of respiratory‐gated 4D dynamic dose calculations for various gating widths without spot timestamp in proton pencil beam scanning en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Proton pencil beam scanning (PBS) is susceptible to dose degradation because of interplay effects on moving targets. For cases of unacceptable motion, respiratory-gated (RG) irradiation is an effective alternative to free breathing (FB) irradiation. However, the introduction of RG irradiation with larger gate widths (GW) is hindered by interplay effects, which are analogous to those observed with FB irradiation. Accurate estimation of interplay effects can be performed by recording spot timestamps. However, our machine lacks this feature, making it imperative to find an alternative approach. Thus, we developed an RG 4-dimensional dynamic dose (RG-4DDD) system without spot timestamps.
Purpose: This study aimed to investigate the accuracy of calculated doses from the RG-4DDD system for PBS plans with varying breathing curves, amplitudes, and periods for 10%–50% GW.
Methods: RG-4DDDs were reconstructed using in-house developed software that assigned timestamps to individual spots, integrated start times for spills with breathing curves, and utilized deformable registrations for dose accumulation. Three cubic verification plans were created using a heterogeneous phantom. Additionally, typical liver and lung cases were employed for patient plan validation. Single- and multi-field-optimized (SFO and IMPT) plans (ten beams in total) were created for the liver and lung cases in a homogeneous phantom. Lateral profile measurements were obtained under both motion and no-motion conditions using a 2D ionization chamber array (2D-array) and EBT3 Gafchromic films on the CIRS dynamic platform. Breathing curves from the cubic plans were used to assess nine patterns of sine curves, with amplitudes of 5.0–10.0 mm (10.0–20.0 mm target motions) and periods of 3–6 sec. Patient field verifications were conducted using a representative patient curve with an average amplitude of 6.4 mm and period of 3.2 sec. Additional simulations were performed assuming a ± 10% change in assigned timestamps for the dose rate (DR), spot spill (0.08-s), and gate time delay (0.1-s) to evaluate the effect of parameter selection on our 4DDD models. The 4DDDs were compared with measured values using the 2D gamma index and absolute doses over that required for dosing 95% of the target.
Results: The 2D-array measurements showed that average gamma scores for the reference (no motion) and 4DDD plans for all GWs were at least 99.9 ± 0.2% and 98.2 ± 2.4% at 3%/3 mm, respectively. The gamma scores of the 4DDDs in film measurements exceeded 95.4% and 92.9% at 2%/2 mm for the cubic and patient plans, respectively. The 4DDD calculations were acceptable under DR changes of ±10% and both spill and gate time delays of ±0.18 sec. For the 4DDD plan using all GWs for all measurement points, the absolute point differences for all validation plans were within ±5.0% for 99.1% of the points.
Conclusions: The RG-4DDD calculations (less than 50% GW) of the heterogeneous and actual patient plans showed good agreement with measurements for various breathing curves in the amplitudes and periods described above. The proposed system allows us to evaluate actual RG irradiation without requiring the ability to record spot timestamps. en-copyright= kn-copyright= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaYushi en-aut-sei=Wakisaka en-aut-mei=Yushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoTakahiro en-aut-sei=Kato en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IchiharaMasaya en-aut-sei=Ichihara en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKeisuke en-aut-sei=Yasui en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiMotoharu en-aut-sei=Sasaki en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishioTeiji en-aut-sei=Nishio en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiotherapy, Medical Co.

However, the vector’s shortcomings limit its utility to transient expression only, as it is not suitable for establishing stable transformants in mammalian cells. To overcome this weakness, we here introduce the improved plasmid vector pSAKA-4B, derived from pCMViR-TSC as a second-generation chromosome-insertable vector. This vector facilitates the linear entry of the expression unit into the TTAA site of DNA universally with transposase assistance. The vector is helpful for the indefinite expression of our target gene. The new vector system is proven here to be efficient in establishing stable transformants with a high likelihood of positive clones that exhibit significantly elevated expression levels of the delivered foreign gene. This system, alongside the first-generation vector, is therefore instrumental for diverse basic research endeavors concerning genes, proteins, cells, and animals, and potentially for clinical applications such as gene therapy. en-copyright= kn-copyright= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Although ICI is used to prevent recurrence by targeting residual microtumors, biomarkers capable of monitoring immune activity during this phase remain lacking. Here, we evaluated whether temporal changes in serum autoantibody levels can predict treatment efficacy. This retrospective study included 20 patients with unresectable stage II or III NSCLC who received the PACIFIC regimen. Serum autoantibodies against 130 antigens were quantified before CRT, after CRT, and two weeks after the first ICI dose. The primary outcome was progression-free survival (PFS), and its association with autoantibody dynamics was examined. We observed an immediate and strong autoantibody response (spark response [SR]) after ICI initiation in patients with favorable treatment outcomes. Patients with SR and programmed death ligand 1 (PD-L1) expression ≥ 50% showed better PFS (two-year PFS; 72.9% vs. 18.2%, p = 0.0021). These findings suggest that serial monitoring of serum autoantibodies can provide a noninvasive approach to assess immune activity and predict treatment outcomes in patients receiving CRT or ICI therapy. en-copyright= kn-copyright= en-aut-name=MoriTakeru en-aut-sei=Mori en-aut-mei=Takeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitagawaMio en-aut-sei=Kitagawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaTomokazu en-aut-sei=Hasegawa en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SomeyaMasanori en-aut-sei=Someya en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuchiyaTakaaki en-aut-sei=Tsuchiya en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GochoToshio en-aut-sei=Gocho en-aut-mei=Toshio 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=DateMirei en-aut-sei=Date en-aut-mei=Mirei 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=MiyamotoAi en-aut-sei=Miyamoto en-aut-mei=Ai 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=Department of Radiology, Sapporo Medical University School of Medicine kn-affil= affil-num=3 en-affil=Department of Radiology, Sapporo Medical University School of Medicine kn-affil= affil-num=4 en-affil=Department of Radiology, Sapporo Medical University School of Medicine kn-affil= affil-num=5 en-affil=Department of Radiology, Sapporo Medical University School of Medicine kn-affil= affil-num=6 en-affil=Department of Radiology, Sapporo Medical University School of Medicine 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=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University 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=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Autoantibodies kn-keyword=Autoantibodies en-keyword=PACIFIC regimen kn-keyword=PACIFIC regimen en-keyword=ICIs kn-keyword=ICIs en-keyword=Immune monitoring kn-keyword=Immune monitoring END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue=32 article-no= start-page=e2501933122 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250805 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural insights into a citrate transporter that mediates aluminum tolerance in barley en-subtitle= kn-subtitle= en-abstract= kn-abstract=HvAACT1 is a major aluminum (Al)-tolerance gene in barley, encoding a citrate transporter that belongs to the multidrug and toxic compound extrusion (MATE) family. This transporter facilitates citrate secretion from the roots, thereby detoxifying external Al ions—a major constraint of crop production on acidic soils. In this study, we present the outward-facing crystal structure of HvAACT1, providing insights into a citrate transport mechanism. The putative citrate binding site consists of three basic residues—K126 in transmembrane helix 2 (TM2), R358 in TM7, and R535 in TM12—creating substantial positive charges in the C-lobe cavity. Proton coupling for substrate transport may involve two pairs of aspartate residues in the N-lobe cavity, one of which corresponds to the essential Asp pair found in prokaryotic H+-coupled MATE transporters belonging to the DinF subfamily. Structural coupling between proton uptake in the N-lobe and citrate extrusion in the C-lobe can be enabled by an extensive, unique hydrogen-bonding network at the extracellular half of the N-lobe. Mutation-based functional analysis, structural comparisons, molecular dynamics simulation, and phylogenic analysis suggest an evolutionary link between citrate MATE transporters and the DinF MATE subfamily. Our findings provide a solid structural basis for citrate transport by HvAACT1 in barley and contribute to a broader understanding of citrate transporter structures in other plant species. en-copyright= kn-copyright= en-aut-name=Nguyen ThaoTran en-aut-sei=Nguyen Thao en-aut-mei=Tran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Mitani-UenoNamiki en-aut-sei=Mitani-Ueno en-aut-mei=Namiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UranoRyo en-aut-sei=Urano en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitohYasunori en-aut-sei=Saitoh en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangPeitong en-aut-sei=Wang en-aut-mei=Peitong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinodaWataru en-aut-sei=Shinoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SugaMichihiro en-aut-sei=Suga en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Degree Program in Interdisciplinary Sciences, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Core for Plant Stress Science, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Division of Superconducting and Functional Materials, Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Degree Program in Interdisciplinary Sciences, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Core for Plant Stress Science, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Research Core for Plant Stress Science, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Degree Program in Interdisciplinary Sciences, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=8 en-affil=Degree Program in Interdisciplinary Sciences, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= affil-num=9 en-affil=Research Core for Plant Stress Science, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=10 en-affil=Degree Program in Interdisciplinary Sciences, Graduate School of Environmental, Life, Natural Science, and Technology, Okayama University kn-affil= en-keyword=barley kn-keyword=barley en-keyword=aluminum resistance kn-keyword=aluminum resistance en-keyword=membrane protein structure kn-keyword=membrane protein structure en-keyword=citrate transporter kn-keyword=citrate transporter en-keyword=MATE transporter kn-keyword=MATE transporter END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dual roles of suberin deposition at the endodermal Casparian strip in manganese uptake of rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice roots are characterized by having two Casparian strips (CSs) at the exodermis and endodermis, where transporters for mineral nutrients are expressed. However, the exact role of the CS in expression of the transporters and subsequent nutrient uptake is poorly understood. Here, we first investigated the role of the CS in manganese (Mn) uptake by using a rice mutant (oscasp1) defective in formation of the endodermal CS. Knockout of OsCASP1 resulted in decreased Mn uptake under limited Mn conditions, but increased Mn uptake at high Mn concentration. Immunostaining revealed that knockout of OsCASP1 did not affect the cell specificity of localization of two transporters (OsNramp5 and OsMTP9) required for Mn uptake, but decreased the protein abundance of these transporters at the endodermis regardless of Mn concentrations tested. Furthermore, we found that overaccumulation of suberin at the endodermis of the mutants suppressed the expression of two transporters; the expression of the two transporters was only observed in the endodermal cells without suberin deposition, but not in the cells with suberin deposition. Taken together, our results indicate that there are two roles for the CS in Mn uptake; maintaining normal expression of the transporters at limited Mn concentration and preventing Mn diffusion to the stele at high Mn concentration. en-copyright= kn-copyright= en-aut-name=FujiiToshiki en-aut-sei=Fujii en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= en-keyword=Casparian strip kn-keyword=Casparian strip en-keyword=endodermis kn-keyword=endodermis en-keyword=manganese transporter kn-keyword=manganese transporter en-keyword=rice kn-keyword=rice en-keyword=root kn-keyword=root en-keyword=suberin deposition kn-keyword=suberin deposition END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=9 article-no= start-page=e70105 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ultrahigh‐Field MR‐Compatible Mechanical Tactile Stimulator for Investigating Somatosensory Processing in Small‐Bodied Animals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Common marmosets (Callithrix jacchus), small-bodied New World primates that share similar sensory processing pathways with human beings, have gained great interests. Their small body size allows imaging of brain activity with high spatial resolution and on a whole-brain scale using ultrahigh-field (UHF) magnetic resonance imaging (MRI) scanners. However, the strong magnetic field and the small size of the hand and forearm pose challenges in delivering tactile stimulation during fMRI experiments. In the present study, we developed an MR-compatible tactile dual-point stimulator to provide high-precision mechanical stimulation for exploring somatosensory processing in small-bodied animals. The study population consisted of a water phantom and three male common marmosets. Cerebral blood volume (CBV) weighted fMRI data were obtained with a gradient echo (GE), echo-planar imaging (EPI) sequence at 7T scanner. The output performance of the device was tested by a pressure sensor. The MR compatibility of the device was verified by measuring the temporal signal-to-noise ratio (tSNR) of a water phantom. To test the effectiveness of tactile stimulation, we conducted block designed tactile stimulation experiments on marmosets. A one-way repeated measures ANOVA was conducted for comparing the tSNR results. We performed one-sample t-tests to investigate the negative response of the forearm and hand stimulation with a threshold of t > 1.96 (p < 0.05). Performance tests revealed that mechanical stimulation (averaged force: 31.69 g) was applied with a delay of 12 ms. Phantom experiments confirmed that there was no significant difference in the tSNR among three (10 Hz, 1 Hz, and no-stimulus) conditions (F (2, 798) = 0.71, p = 0.49). The CBV activity results showed that the stimulator successfully elicited hand and forearm somatosensory activations in primary somatosensory areas. These results indicated that the device is well suited for small-bodied animal somatosensory studies. en-copyright= kn-copyright= en-aut-name=WangChenyu en-aut-sei=Wang en-aut-mei=Chenyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImaiHirohiko en-aut-sei=Imai en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukunagaMasaki en-aut-sei=Fukunaga en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoHiroki en-aut-sei=Yamamoto en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SekiKazuhiko en-aut-sei=Seki en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HanakawaTakashi en-aut-sei=Hanakawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmedaTatsuya en-aut-sei=Umeda en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=Innovation Research Center for Quantum Medicine, Gifu University School of Medicine kn-affil= affil-num=3 en-affil=Section of Brain Function Information, National Institute for Physiological Sciences kn-affil= affil-num=4 en-affil=Graduate School of Human and Environmental Studies, Kyoto 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=Department of Neurophysiology, National Center of Neurology and Psychiatry kn-affil= affil-num=7 en-affil=Department of Integrated Neuroanatomy and Neuroimaging, Kyoto University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Integrated Neuroanatomy and Neuroimaging, Kyoto University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=primary somatosensory cortex kn-keyword=primary somatosensory cortex en-keyword=small-bodied animals kn-keyword=small-bodied animals en-keyword=tactile stimulation device kn-keyword=tactile stimulation device en-keyword=ultrahigh-field magnetic resonance imaging kn-keyword=ultrahigh-field magnetic resonance imaging END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue= article-no= start-page=e60943 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250729 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of Interventions Using a Smartphone Cognitive Behavior Therapy Application for Children With Mental Health Disorders: Prospective, Single-Arm, Uncontrolled Clinical Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The prevalence of mental health disorders among children in Japan has increased rapidly, and these children often show depressive symptoms and reduced quality of life (QOL). We previously developed a smartphone-based self-monitoring app to deliver cognitive behavioral therapy (CBT), implemented it in healthy children, and reported its effectiveness for health promotion.
Objective: This study aims to examine the usefulness of the CBT app for improvement in depressive symptoms and QOL in children with mental health disorders.
Methods: The participants were 115 children with mental health disorders (eg, school refusal, orthostatic hypotension, eating disorders, developmental disorders, among others) and aged 12‐18 years. The CBT app–based program comprised 1 week of psychoeducation followed by 1 week of self-monitoring. After reading story-like scenarios, participants created a self-monitoring sheet with 5 panels: events, thoughts, feelings, body responses, and actions. All participants received regular mental health care from physicians in addition to the app-based program. To evaluate the participants’ depressive symptoms and QOL, Patient Health Questionnaire for Adolescents (PHQ-9A), Depression Self-Rating Scale for Children (DSRS-C), and Pediatric Quality of Life Inventory (PedsQL) were measured at the beginning of the intervention, and at 2 and 6 months thereafter. Questionnaire for Triage and Assessment with 30 items (QTA30), and Rosenberg Self-Esteem Scale (RSES) were also used to measure their health and self-esteem. Participants were divided into 4 groups on the basis of the PHQ-9A score (above or below the cutoff; PHQ-9A≥5 or PHQ-9A<5) and completion or noncompletion of the CBT app–based program (app [+] or app [-]). The primary outcome was improvement in the DSRS-C score, and secondary outcomes were improvement in other psychometric scales including PedsQL, QTA30, and RSE. A paired-samples t test was used for statistical analysis. The Medical Ethics Committee of Fukuoka University Faculty of Medicine (approval U22-05-002) approved the study design.
Results: There were 48, 18, 18, and 7 participants in the PHQ-9A≥5 app (+), PHQ-9A≥5 app (-), PHQ-9A<5 app (+), and PHQ-9A<5 app (-) groups, respectively. A total of 24 participants dropped out. No improvement in the DSRS-C score was observed in all groups. However, PedsQL scores improved significantly at 2 and 6 months in the PHQ-9A<5 app (+) group (t17=6.62; P<.001 and t17=6.11; P<.001, respectively). There was a significant positive correlation between the PHQ-9A scores and the number of self-monitoring sheets completed.
Conclusions: The CBT app was useful for improving PedsQL scores of children with mental health disorders. However, a higher-intensity CBT program is necessary for more severely depressed children.

en-abstract=　This study aims to theoretically examine prior research on the locus of innovation, with a particular focus on clarifying "when," "where," and "by whom" innovation is generated. The analysis reveals that in the context of B to B (Industrial Goods) , the shift of innovation sources toward enterprise users has been explained from the perspective of economic rationality, incorporating multiple factors such as transaction cost, expected innovation rents, sticky information, internal capabilities (Absorptive Capacity) , and external industrial structures (Product Architecture, Ecosystem) . In contrast, in the B to C context (Consumer Goods) , end users pursue innovation for a wide variety of reasons, including manufacturers' lack of responsiveness to niche markets, the enjoyment of creative activity, connection with user communities, and personal growth. Among these, the enjoyment derived from creative activity has deemed to be identified as one of the most fundamental motivational factors. However, the methodological articulation of such psychological factors is not enough. Leaving the psychological drivers behind innovation as a black box is not merely a matter of academic curiosity but presents a significant challenge for management studies as a social science. This is because management is always purposive attempts for directing and controlling the process of value creation and sometimes psychological exaltation, which may be recently called 'flow' experience, may conflict such attempts. In future research on the locus of innovation, it is essential to focus on these psychological aspects of individual innovator and to develop new research approaches. First, it has a room for further elucidation of the mechanisms by which positive emotions contribute to innovation, but this challenge is hardly easy to overcome. Since creativity is essentially a construct of the individual level and innovation is not, the argument of balancing the entrepreneurial motivational drivers and the managerial direction and control of creative destruction needs to be mediated by meso-level constructs. In our prospect, such concepts as underdeveloped ecosystem on the supply side and immature connoisseur on the side of consumers may be promising. Another concern is the generally limited sample size of creative minds. The existent research tactics that have been found in our neighboring disciplines sharing the same problem as ours, either qualitative or quantitative, may provide us with methodical benchmarks. kn-abstract=　本論文は，イノベーションの発生源に関する先行研究を振り返り，「いつ」「どこで」「誰によって」イノベーションが生み出されるのかを理論的に考察することを目的とする。考察の結果，「B to B」の文脈においては，イノベーションの発生源が企業ユーザーへ移行するメカニズムとして，取引コスト理論，期待利益仮説，情報粘着性の仮説，企業内部の独自能力（吸収能力），および外部の産業構造（製品アーキテクチャ・エコシステム）といった複数の要素からなる経済的合理性の観点から分析されていることが明らかになった。一方，「B to C」の文脈では，エンドユーザーがイノベーションに向かう動機として，「ニッチ市場に対するメーカーの消極的な対応」「創造的活動の楽しさ」「ユーザーコミュニティとの繋がり」「知識・スキルの向上」など多種多様な要素が存在し，中でも創造的活動の楽しさが根源的な動機づけの1つであると確認された。一方で，イノベーターを突き動かす心理的要因をブラックボックス化したまま放置することは，単なる知的好奇心の問題に留まらず，社会科学としての経営学にとっても重要な問題であると考えられる。今後のイノベーションの発生源研究においては，起業家をはじめとするイノベーター個人の心理的側面にいかに目を向け，創造的活動におけるポジティブな感情が働くメカニズムをイノベーションの発生メカニズムにいかに位置づけるか，その研究アプローチの提示が求められる。 en-copyright= kn-copyright= en-aut-name=HuangQi en-aut-sei=Huang en-aut-mei=Qi kn-aut-name=黄琪 kn-aut-sei=黄 kn-aut-mei=琪 aut-affil-num=1 ORCID= en-aut-name=FujiiDaiji en-aut-sei=Fujii en-aut-mei=Daiji kn-aut-name=藤井大児 kn-aut-sei=藤井 kn-aut-mei=大児 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院ヘルスシステム統合科学研究科 affil-num=2 en-affil= 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=イノベーションの発生源 (Locus of Innovation) kn-keyword=イノベーションの発生源 (Locus of Innovation) en-keyword=ユーザーイノベーション (User Innovation) kn-keyword=ユーザーイノベーション (User Innovation) en-keyword=経済的合理性 (Economic Rationality) kn-keyword=経済的合理性 (Economic Rationality) en-keyword=内発的動機づけ (Intrinsic Motivation) kn-keyword=内発的動機づけ (Intrinsic Motivation) en-keyword=フロー体験 (Flow Experience) kn-keyword=フロー体験 (Flow Experience) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=10712 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Shoot-Silicon-Signal protein to regulate root silicon uptake in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plants accumulate silicon to protect them from biotic and abiotic stresses. Especially in rice (Oryza sativa), a typical Si-accumulator, tremendous Si accumulation is indispensable for healthy growth and productivity. Here, we report a shoot-expressed signaling protein, Shoot-Silicon-Signal (SSS), an exceptional homolog of the flowering hormone “florigen” differentiated in Poaceae. SSS transcript is only detected in the shoot, whereas the SSS protein is also detected in the root and phloem sap. When Si is supplied from the root, the SSS transcript rapidly decreases, and then the SSS protein disappears. In sss mutants, root Si uptake and expression of Si transporters are decreased to a basal level regardless of the Si supply. The grain yield of the mutants is decreased to 1/3 due to insufficient Si accumulation. Thus, SSS is a key phloem-mobile protein for integrating root Si uptake and shoot Si accumulation underlying the terrestrial adaptation strategy of grasses. en-copyright= kn-copyright= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Mitani-UenoNamiki en-aut-sei=Mitani-Ueno en-aut-mei=Namiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiToshiki en-aut-sei=Fujii en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShinyaTomonori en-aut-sei=Shinya en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShaoJi Feng en-aut-sei=Shao en-aut-mei=Ji Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WatanukiShota en-aut-sei=Watanuki en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitohYasunori en-aut-sei=Saitoh en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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 Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=State Key Laboratory of Subtropical Silviculture, Zhejiang Agriculture & Forestry University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=23 article-no= start-page=17720 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=A meta-linked isomer of ITIC: influence of aggregation patterns on open-circuit voltage in organic solar cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Improving the open-circuit voltage (VOC) of organic solar cells (OSCs) remains an important challenge. While it is known that the energy levels at the donor/acceptor (D/A) interface affect the VOC, the impact of aggregation patterns on the energy levels at the D/A interface has not been fully elucidated. Herein, we focus on ITIC, a widely used acceptor in OSCs, and designed a meta-linked isomer of ITIC (referred to as im-ITIC) to alter molecular symmetry and modify substitution arrangements. Concentration-dependent 1H NMR spectra revealed that im-ITIC shows stronger aggregation behavior in solution. Single-crystal X-ray analysis showed that im-ITIC forms both tail-to-tail (J-aggregation) and face-to-face (H-aggregation) stacking modes, whereas ITIC exclusively forms tail-to-tail stacking. OSCs based on PBDB-T:im-ITIC showed a high VOC value of 1.02 V, which is 0.12 V higher than that of those based on PBDB-T:ITIC. Time-resolved infrared measurements revealed the lifetime of free electrons for the pristine and blend films. The energy levels of the charge transfer state (ECT) for PBDB-T:im-ITIC- and PBDB-T:ITIC OSCs were determined to be 1.57 and 1.39 eV, respectively, correlating with the VOC values. Theoretical calculations indicated that pronounced H-aggregation in im-ITIC increases the ECT compared with J-aggregation, contributing to the improved VOC. This study underscores the critical impact of molecular aggregation patterns on energy alignment and VOC enhancement, offering insights into molecular design for achieving high VOC in OSCs. en-copyright= kn-copyright= en-aut-name=WangKai en-aut-sei=Wang en-aut-mei=Kai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=JinnaiSeihou en-aut-sei=Jinnai en-aut-mei=Seihou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UesakaKaito en-aut-sei=Uesaka en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IeYutaka en-aut-sei=Ie en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=The Institute of Scientific and Industrial Research (SANKEN), The University of Osaka kn-affil= affil-num=2 en-affil=The Institute of Scientific and Industrial Research (SANKEN), The University of Osaka kn-affil= affil-num=3 en-affil=Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=5 en-affil=The Institute of Scientific and Industrial Research (SANKEN), The University of Osaka kn-affil= END start-ver=1.4 cd-journal=joma no-vol=599 cd-vols= no-issue=13 article-no= start-page=1914 end-page=1924 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of molecular mechanisms of CaMKKα/1 oligomerization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcium/calmodulin-dependent protein kinase kinase (CaMKK) is an activating kinase for calcium/calmodulin-dependent protein kinase type 1 (CaMKI), calcium/calmodulin-dependent protein kinase type IV (CaMKIV), RAC-alpha serine/threonine-protein kinase (PKB), and AMP-activated protein kinase (AMPK) that has been reported to form an active oligomer in cells. Glutathione S-transferase (GST) pulldown assay from the extracts of COS-7 cells expressing GST- and His6-CaMKKα/1 mutants showed that the C-terminal region containing the autoinhibitory and calmodulin (CaM)-binding sequence (residues 438–463) is required for CaMKKα/1 homo-oligomerization. This was confirmed by the fact that the GST-CaMKKα/1 C-terminal domain (residues 435–505) directly interacted with EGFP-CaMKKα/1 residues 435–505 as well as with wild-type CaMKKα/1. Notably, once oligomerized in cells, CaMKKα/1 is neither exchangeable between the oligomeric complexes nor dissociated by Ca2+/CaM binding. These results support stable oligomerization of CaMKK in the cells by intermolecular self-association of its C-terminal region containing a regulatory domain. en-copyright= kn-copyright= en-aut-name=UenoyamaShun en-aut-sei=Uenoyama en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NittaHayato en-aut-sei=Nitta en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=SuizuFutoshi en-aut-sei=Suizu en-aut-mei=Futoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=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 Medical Technology, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=calmodulin kn-keyword=calmodulin en-keyword=calmodulin-kinase cascade kn-keyword=calmodulin-kinase cascade en-keyword=CaMKKa/ kn-keyword=CaMKKa/ en-keyword=oligomerization kn-keyword=oligomerization en-keyword=protein–protein interaction kn-keyword=protein–protein interaction en-keyword=regulatory domain kn-keyword=regulatory domain END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=10819 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A high-protein diet-responsive gut hormone regulates behavioral and metabolic optimization in Drosophila melanogaster en-subtitle= kn-subtitle= en-abstract= kn-abstract=Protein is essential for all living organisms; however, excessive protein intake can have adverse effects, such as hyperammonemia. Although mechanisms responding to protein deficiency are well-studied, there is a significant gap in our understanding of how organisms adaptively suppress excessive protein intake. In the present study, utilizing the fruit fly, Drosophila melanogaster, we discover that the peptide hormone CCHamide1 (CCHa1), secreted by enteroendocrine cells in response to a high-protein diet (HPD), is vital for suppressing overconsumption of protein. Gut-derived CCHa1 is received by a small subset of enteric neurons that produce short neuropeptide F, thereby modulating protein-specific satiety. Importantly, impairment of the CCHa1-mediated gut-enteric neuronal axis results in ammonia accumulation and a shortened lifespan under HPD conditions. Collectively, our findings unravel the crosstalk of gut hormone and neuronal pathways that orchestrate physiological responses to prevent and adapt to dietary protein overload. en-copyright= kn-copyright= en-aut-name=YoshinariYuto en-aut-sei=Yoshinari en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraTakashi en-aut-sei=Nishimura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoShu en-aut-sei=Kondo en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanimotoHiromu en-aut-sei=Tanimoto en-aut-mei=Hiromu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiTomoe en-aut-sei=Kobayashi en-aut-mei=Tomoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuyamaMakoto en-aut-sei=Matsuyama en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NiwaRyusuke en-aut-sei=Niwa en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Metabolic Regulation and Genetics, Institute for Molecular and Cellular Regulation, Gunma University kn-affil= affil-num=2 en-affil=Metabolic Regulation and Genetics, Institute for Molecular and Cellular Regulation, Gunma University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=5 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=6 en-affil=Division of Molecular Genetics, Shigei Medical Research Institute kn-affil= affil-num=7 en-affil=Division of Molecular Genetics, Shigei Medical Research Institute kn-affil= affil-num=8 en-affil=Life Science Center for Survival Dynamics, Tsukuba Advanced Research Alliance (TARA), University of Tsukuba kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=5 article-no= start-page=489 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mutagenesis Targeting the S153 Residue Within the Transmembrane β-Hairpin of Mosquito-Larvicidal Mpp46Ab Affects Its Toxicity and the Synergistic Toxicity with Cry4Aa en-subtitle= kn-subtitle= en-abstract= kn-abstract=We constructed a library of Mpp46Ab mutants, in which S153 within the transmembrane β-hairpin was randomly replaced by other amino acids. Mutagenesis and subsequent primary screening yielded 10 different Mpp46Ab mutants in addition to the wild type. Remarkably, S153 was replaced with a more hydrophobic amino acid in most of the mutants, and the S153I mutant in particular exhibited significantly increased toxicity. Electrophysiologic analysis using artificial lipid bilayers revealed that the single-channel conductance and PK/PCl permeability ratio were significantly increased for S153I pores. This suggests that the formation of highly ion-permeable and highly cation-selective toxin pores increases the influx of cations and water into cells, thereby facilitating osmotic shock. In addition, the S153F, S153L, and S153I mutants exhibited significantly reduced synergistic toxicity with Cry4Aa. Electrophysiologic analysis showed that the S153F, S153L, and S153I mutants form toxin pores with a significantly reduced PK/PNa permeability ratio and a significantly increased PK/PCa permeability ratio compared to wild-type pores. Thus, our results suggest that pore formation is central to the insecticidal activity of Mpp46Ab and that the ion permeability of toxin pores is a potential indicator correlated with both toxicity and synergistic toxicity with other toxins. en-copyright= kn-copyright= en-aut-name=HayakawaTohru en-aut-sei=Hayakawa en-aut-mei=Tohru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamaokaSyun en-aut-sei=Yamaoka en-aut-mei=Syun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsakuraMami en-aut-sei=Asakura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoMinako en-aut-sei=Hirano en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IdeToru en-aut-sei=Ide en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=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= en-keyword=Bacillus thuringiensis kn-keyword=Bacillus thuringiensis en-keyword=mosquito-larvicidal proteins kn-keyword=mosquito-larvicidal proteins en-keyword=synergistic toxicity kn-keyword=synergistic toxicity en-keyword=Culex pipiens mosquito larvae kn-keyword=Culex pipiens mosquito larvae en-keyword=side-directed mutagenesis kn-keyword=side-directed mutagenesis en-keyword=electrophysiologic analysis kn-keyword=electrophysiologic analysis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=100242 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photochemical internalization of mRNA using a photosensitizer and nucleic acid carriers en-subtitle= kn-subtitle= en-abstract= kn-abstract=mRNA has great potential for therapeutic applications because it can encode a variety of proteins and antigens, in addition to advantages over DNA in terms of gene expression without genomic integration, nuclear localization, or transcription. However, therapeutic applications of mRNA require safe and effective delivery into target cells. Therefore, we aimed to investigate photochemical internalization (PCI) as a promising strategy for delivering mRNA to target cells. In this strategy, mRNA is taken up into cells by endocytosis, accumulates in endosomes, and is released in a light-dependent manner from the endosomes using an endosome-accumulating photosensitizer, aluminum phthalocyanine disulfonate (AlPcS2a), in combination with nucleic acid carrier molecules. We compared the efficacy of various nucleic acid carriers, including branched polyethyleneimine (bPEI) and poly{N'-[N-(2-aminoethyl)-2-aminoethyl] aspartamide} (PAsp(DET)) under the same conditions for PCI-based mRNA delivery. Our results indicated that bPEI and PAsp(DET) at low N/P ratios exhibited efficient light-enhancement of mRNA expression by PCI with AlPcS2a. Notably, bPEI exhibited the highest light-dependent mRNA delivery among the carriers evaluated (including cationic polymers, cationic peptides, and lipids), whereas PAsp(DET) showed promise for clinical use because of its lower toxicity compared with bPEI. This PCI strategy allows effective cytosolic mRNA delivery at low N/P ratios, thereby reducing cationic carrier molecule-induced cytotoxicity. This method allows spatiotemporal control of protein expression and holds potential for novel light-dependent mRNA therapies. Overall, this study provided valuable insights into optimizing mRNA delivery systems for therapeutic applications. en-copyright= kn-copyright= en-aut-name=MaemotoHayaki en-aut-sei=Maemoto en-aut-mei=Hayaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzakiRyohei en-aut-sei=Suzaki en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=ItakaKeiji en-aut-sei=Itaka en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Biofunction Research, Institute of Biomaterials and Bioengineering, Tokyo Medical and Dental University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=mRNA kn-keyword=mRNA en-keyword=Photochemical internalization kn-keyword=Photochemical internalization en-keyword=Photosensitizer kn-keyword=Photosensitizer END start-ver=1.4 cd-journal=joma no-vol=91 cd-vols= no-issue=946 article-no= start-page=24-00128 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=Development of a guideline proposal system for correcting cutting conditions based on the overhang length of ball end-mills kn-title=ボールエンドミルの突き出し長さに応じた切削条件補正システムの開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the field of die and mold machining, determining appropriate cutting conditions is crucial. Factors such as tool geometry, machining path, work material characteristics, machining efficiency, and finishing accuracy must be taken into consideration. However, the current method of determining cutting conditions relies heavily on the intuition and experience of skilled engineers, and there is a need for a system to replace such knowledge. One of the critical factors affecting machining accuracy and efficiency is the tool overhang length, which is directly related to tool geometry. Unfortunately, there is no clear guideline for its determination. In a previous study, researchers developed a system to quickly derive cutting conditions using a data mining method and Random Forest Regression (RFR) applied to a tool catalog database. In this study, we constructed a new cutting condition compensation system based on the existing model, which accounts for the tool overhang length. The results of cutting experiments under high aspect ratio overhang lengths confirm that the correction coefficients proposed by the system are significant. en-copyright= kn-copyright= en-aut-name=KODAMAHiroyuki en-aut-sei=KODAMA en-aut-mei=Hiroyuki kn-aut-name=児玉紘幸 kn-aut-sei=児玉 kn-aut-mei=紘幸 aut-affil-num=1 ORCID= en-aut-name=MORIYAYuki en-aut-sei=MORIYA en-aut-mei=Yuki kn-aut-name=守屋祐輝 kn-aut-sei=守屋 kn-aut-mei=祐輝 aut-affil-num=2 ORCID= en-aut-name=MORIMOTOTatsuo en-aut-sei=MORIMOTO en-aut-mei=Tatsuo kn-aut-name=盛元達雄 kn-aut-sei=盛元 kn-aut-mei=達雄 aut-affil-num=3 ORCID= en-aut-name=OHASHIKazuhito en-aut-sei=OHASHI en-aut-mei=Kazuhito kn-aut-name=大橋一仁 kn-aut-sei=大橋 kn-aut-mei=一仁 aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, 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=2 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 大学院環境生命自然科学研究科 affil-num=3 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 大学院環境生命自然科学研究科 affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, 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=Data mining kn-keyword=Data mining en-keyword=Cutting conditions kn-keyword=Cutting conditions en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Random Forest Regression kn-keyword=Random Forest Regression en-keyword=Ball end-mill kn-keyword=Ball end-mill en-keyword=Tool overhang length kn-keyword=Tool overhang length END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=6 article-no= start-page=e70119 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Quantitative quality control of 3D water tank using image analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and objective: Accurate beam data acquisition using three-dimensional (3D) water tanks is essential for beam commissioning and quality control (QC) in clinical radiation therapy. This study introduces a novel method for quantitative QC of the system, utilizing MV images and webcam videos. The stability of the motor drive speed and the positional accuracy of the fixture were evaluated under two measurement modes: “continuous mode” and “step-by-step mode.”
Methods: A TRUFIX mounting system (PTW Freiburg Inc., Germany) was used to attach the center of the steel ball to its top, ensuring alignment with the water surface of the tank. To assess deviations from the radiation isocenter, MV images were acquired and compared with digitally reconstructed radiographs (DRRs). These evaluations were performed at different speed settings (slow, medium, and fast) using ET CT Body Marker (BRAINLAB Inc., USA) mounted on the drive unit. A webcam was utilized to capture the images, and custom-developed tracking software was employed to analyze deviations in driving speed and positional errors.
Results: The mean error of the radiation isocenter was 0.37 ± 0.09 mm. As the motor drive speed increased, the discrepancy between the set speed and the actual speed observed in the analysis also became larger. In “continuous mode,” the deviation from the displayed value was greater than that observed in “step-by-step mode.”
Conclusion: It is demonstrated that the proposed analysis method can quantitatively evaluate radiation isocenter misalignment, tank setup position deviation, and both the indicated drive speed values and their stability. At higher drive speeds, the “step-by-step mode” showed smaller deviations from the indicated values. en-copyright= kn-copyright= en-aut-name=TanimotoYuki en-aut-sei=Tanimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoshiKazunobu en-aut-sei=Koshi en-aut-mei=Kazunobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiroshigeAkira en-aut-sei=Hiroshige en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaShohei en-aut-sei=Yoshida en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujitaYoshiki en-aut-sei=Fujita en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakahiraAtsuki en-aut-sei=Nakahira en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanishiDaiki en-aut-sei=Nakanishi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HondaHirofumi en-aut-sei=Honda en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, NHO Kure Medical Center and Chugoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=3 en-affil=Department of Radiology, NHO Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Division of Radiology, Department of Medical Technology, Kyushu University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Ehime University Hospital kn-affil= affil-num=10 en-affil=Department of Healthcare Science, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=3D water tank kn-keyword=3D water tank en-keyword=drive speed stability kn-keyword=drive speed stability en-keyword=quality control kn-keyword=quality control en-keyword=radiation isocenter kn-keyword=radiation isocenter en-keyword=x-ray image analysis kn-keyword=x-ray image analysis END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=78 end-page=85 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Standardization of radiation therapy quality control system through mutual quality control based on failure mode and effects analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The advancement of irradiation technology has increased the demand for quality control of radiation therapy equipment. Consequently, the number of quality control items and required personnel have also increased. However, differences in the proportion of qualified personnel to irradiation techniques have caused bias in quality control systems among institutions. To standardize the quality across institutions, researchers should conduct mutual quality control by analyzing the quality control data of one institution at another institution and comparing the results with those of their own institutions. This study uses failure mode and effects analysis (FMEA) to identify potential risks in 12 radiation therapy institutions, compares the results before and after implementation of mutual quality control, and examines the utility of mutual quality control in risk reduction. Furthermore, a cost-effectiveness factor is introduced into FMEA to evaluate the utility of mutual quality control. en-copyright= kn-copyright= en-aut-name=TanimotoYuki en-aut-sei=Tanimoto

kn-title=南西諸島の前弧域における付加体を含む堆積層のモデル化 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　We combine the recent seismic reflection profiles to construct a new seismic velocity model of the sedimentary layer incorporating the accretionary prism along the Ryukyu trench. In constructing the new model, we refer to the zoning (ZONE1 to ZONE4) identified by Okamura et al. (2017, Tectonophys.). The construction process consists of the following steps: First, we digitize either unconformities or VP=4 to 5 km/s lines as the seismic basement, whichever is more clearly identifiable. Second, the digitized thickness data of the sedimentary layer from the reflection profiles are geometrically modeled and interpolated to make the three-dimensional structure model. Finally, we supplement the external region of the constructed 3-D sedimentary model using the J-SHIS model provided by the NIED to complete the velocity structure model in the entire Ryukyu arc. The main features of our model are as follows: In ZONE1, off Ishigaki-jima island, the thick sedimentary layer extends about 50 km wide from the Ryukyu trench. In ZONE2, off Miyako-jima island, the thinner layer compared to the other zones is found near the trench, with a thin sedimentary terrace covering the area behind it. In ZONE3, off Okinawa-jima island, the sedimentary layer deepens as it approaches the trench. In ZONE4, off Tokara islands, the deepest layer among all zones is identified. We then conduct 3-D finite-difference simulations of seismic wave propagation using the new and the previous models to confirm the improvement of the new model. In the simulations, the effects of the accretionary prism along the Ryukyu trench on the seismic wave propagation are clearly identified. en-copyright= kn-copyright= en-aut-name=KOMATSUMasanao

of society, family, and other factors. In many cases, patients have the capacity to make the decisions; nevertheless, they have difficulty expressing their own will because of the influence of their relationships and environment. Patient concerns about the burden of care and also the social and economic impacts on family members often hinder their use of imagination and decision-making. Therefore, this study has examined how patients with decision-making capacities could achieve autonomy under the influence of their relationships with their surroundings. The method of decision-making support provided by nurses to patients was examined using relational autonomy theory. Relational autonomy theory attempts to reconceptualize autonomy through feminists who criticize individualist theories of autonomy. en-copyright= kn-copyright= en-aut-name=SONOYAMASumiyo en-aut-sei=SONOYAMA en-aut-mei=Sumiyo kn-aut-name=園山純代 kn-aut-sei=園山 kn-aut-mei=純代 aut-affil-num=1 ORCID= affil-num=1 en-affil=The University of Shimane kn-affil=島根県立大学 en-keyword=relational autonomy kn-keyword=relational autonomy en-keyword=decision-making kn-keyword=decision-making en-keyword=end of life care kn-keyword=end of life care END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Corporate decision-making process for exploration time kn-title=知の探索時間についての企業の意思決定プロセス en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order for companies to innovate through business co-creation, it is necessary to explore a wide range of external knowledge and technologies. However, there is no clear answer as to how much time should be spent for exploration. Under these circumstances, companies must take into account constraints such as the amount of management resources that can be invested, and make decisions about the time to spend for exploration. The purpose of this paper is to clarify the process of how companies that have introduced corporate accelerator program recognize the relationship between the program period and the results of business co-creation, and how they make decisions about the program period. We conducted a case study of several companies that have introduced corporate accelerator program in Japan. In addition, this paper established a hypothesis about decision-making about the time for exploration from case studies. en-copyright= kn-copyright= en-aut-name=SHIMIZUTakeshi en-aut-sei=SHIMIZU en-aut-mei=Takeshi kn-aut-name=志水武史 kn-aut-sei=志水 kn-aut-mei=武史 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=corporate accelerator program kn-keyword=corporate accelerator program en-keyword=co-creation kn-keyword=co-creation en-keyword=exploration kn-keyword=exploration en-keyword=Time Compression Diseconomies kn-keyword=Time Compression Diseconomies END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 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=15 cd-vols= no-issue=6 article-no= start-page=668 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robustness of Machine Learning Predictions for Determining Whether Deep Inspiration Breath-Hold Is Required in Breast Cancer Radiation Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Deep inspiration breath-hold (DIBH) is a commonly used technique to reduce the mean heart dose (MHD), which is critical for minimizing late cardiac side effects in breast cancer patients undergoing radiation therapy (RT). Although previous studies have explored the potential of machine learning (ML) to predict which patients might benefit from DIBH, none have rigorously assessed ML model performance across various MHD thresholds and parameter settings. This study aims to evaluate the robustness of ML models in predicting the need for DIBH across different clinical scenarios. Methods: Using data from 207 breast cancer patients treated with RT, we developed and tested ML models at three MHD cut-off values (240, 270, and 300 cGy), considering variations in the number of independent variables (three vs. six) and folds in the cross-validation (three, four, and five). Robustness was defined as achieving high F2 scores and low instability in predictive performance. Results: Our findings indicate that the decision tree (DT) model demonstrated consistently high robustness at 240 and 270 cGy, while the random forest model performed optimally at 300 cGy. At 240 cGy, a threshold critical to minimize late cardiac risks, the DT model exhibited stable predictive power, reducing the risk of overestimating DIBH necessity. Conclusions: These results suggest that the DT model, particularly at lower MHD thresholds, may be the most reliable for clinical applications. By providing a tool for targeted DIBH implementation, this model has the potential to enhance patient-specific treatment planning and improve clinical outcomes in RT. en-copyright= kn-copyright=

Performance for Head and Neck Tumors with Simple Diffusion Kurtosis Imaging and Machine Learning Bi-Parameter Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Mean kurtosis (MK) values in simple diffusion kurtosis imaging (SDI)-a type of diffusion kurtosis imaging (DKI)-have been reported to be useful in the diagnosis of head and neck malignancies, for which pre-processing with smoothing filters has been reported to improve the diagnostic accuracy. Multi-parameter analysis using DKI in combination with other image types has recently been reported to improve the diagnostic performance. The purpose of this study was to evaluate the usefulness of machine learning (ML)-based multi-parameter analysis using the MK and apparent diffusion coefficient (ADC) values-which can be acquired simultaneously through SDI-for the differential diagnosis of benign and malignant head and neck tumors, which is important for determining the treatment strategy, as well as examining the usefulness of filter pre-processing. Methods: A total of 32 pathologically diagnosed head and neck tumors were included in the study, and a Gaussian filter was used for image pre-processing. MK and ADC values were extracted from pixels within the tumor area and used as explanatory variables. Five ML algorithms were used to create models for the prediction of tumor status (benign or malignant), which were evaluated through ROC analysis. Results: Bi-parameter analysis with gradient boosting achieved the best diagnostic performance, with an AUC of 0.81. Conclusions: The usefulness of bi-parameter analysis with ML methods for the differential diagnosis of benign and malignant head and neck tumors using SDI data were demonstrated. en-copyright=

Activation of B Cells and CD4+ T Follicular Helper Cells to Sensitize Brain Metastases to Combination Immunotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brain metastasis is a poor prognostic factor in patients with cancer. Despite showing efficacy in many extracranial tumors, immunotherapy with anti–PD-1 mAb or anti–CTLA4 mAb seems to be less effective against intracranial tumors. Promisingly, recent clinical studies have reported that combination therapy with anti–PD-1 and anti–CTLA4 mAbs has a potent antitumor effect on brain metastasis, highlighting the need to elucidate the detailed mechanisms controlling the intracranial tumor microenvironment (TME) to develop effective immunotherapeutic strategies. In this study, we analyzed the tumor-infiltrating lymphocytes in murine models of brain metastasis that responded to anti–CTLA4 and anti–PD-1 mAbs. Activated CD4+ T follicular helper (TFH) cells with high CTLA4 expression characteristically infiltrated the intracranial TME, which were activated by combination anti–CTLA4 and anti–PD-1 treatment. The loss of TFH cells suppressed the additive effect of CTLA4 blockade on anti–PD-1 mAb. B-cell–activating factor belonging to the TNF family (BAFF) and a proliferation-inducing ligand (APRIL) produced by abundant myeloid cells, particularly CD80hiCD206lo proinflammatory M1-like macrophages, in the intracranial TME induced B-cell and TFH-cell infiltration and activation. Furthermore, the intracranial TME of patients with non–small cell lung cancer featured TFH- and B-cell infiltration as tertiary lymphoid structures. Together, these findings provide insights into the immune cell cross-talk in the intracranial TME that facilitates an additive antitumor effect of CTLA4 blockade with anti–PD-1 treatment, supporting the potential of a combination immunotherapeutic strategy for brain metastases.
Significance: B-cell and CD4+ T follicular helper cell activation via BAFF/APRIL from abundant myeloid cells in the intracranial tumor microenvironment enables a combinatorial effect of CTLA4 and PD-1 blockade in brain metastases. en-copyright= kn-copyright= en-aut-name=NinomiyaToshifumi en-aut-sei=Ninomiya en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Needs and Support of Children with Cancer kn-title=小児がん患児に対する教育的支援とその研究動向 en-subtitle= kn-subtitle= en-abstract=　In this study, we summarized research trends related to the educational needs and support of children with cancer from the perspectives of “learning,” “self-management,” “interpersonal,” “psychological,” and “collaboration,”. In terms of learning, the study showed that experiential learning and distance education are solutions to the problem of delayed learning due to prolonged absence from school and poor concentration during treatment. Next, in self-management, it is important to educate affected children so that they can fully understand the disease and treatment. In addition, in terms of interpersonal support, it is difficult for the affected patients to build relationships with friends, but providing opportunities for interaction is expected to contribute to the improvement of interpersonal relationships. In terms of psychological support, the anxiety associated with treatment is a major psychological burden for the affected children, and the understanding of their friends and the intervention of university student volunteers are effective in helping them achieve psychological stability. Finally, the lack of cooperation between medical institutions and schools was highlighted as a deficiency in the support system, which needs to be strengthened. In the future, these support measures should be empirically verified to establish a sustainable support system. kn-abstract=　本研究は、小児がん患児の教育的支援に関する研究の動向を明らかにし、今後の課題とその解決策を提起することを目的とした。「学習」、「自己管理」、「対人」、「心理」、「連携」の5つの視点から分析を行った。学習支援について、治療に伴う学習の遅れや集中力の低下に対し、個別の教育支援計画や体験的な学習、および遠隔教育の実施に期待されていた。自己管理支援では、患児が自身の病状や治療による副作用を理解し、自立的に管理できる能力を育成することが求められていた。対人支援について、患児の長期入院により、友人関係の構築が困難になり、入院中や復学後のコミュニケーションの支援が重要であることが確認された。心理支援においては、周囲への効果的ながん教育や大学生ボランティアによる支援が、患児の心理的安定を促すことが示された。最後に、学校と医療機関、保護者の連携不足が指摘されており、連携ツールの開発が求められている。 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=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=2 ORCID= affil-num=1 en-affil=Graduate School of Education Doctoral Programs, 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=岡山大学学術研究院教育学域 en-keyword=小児がん (child hood cancer) kn-keyword=小児がん (child hood cancer) en-keyword=慢性疾患 (chronic illness) kn-keyword=慢性疾患 (chronic illness) en-keyword=教育的ニーズ (educational needs) kn-keyword=教育的ニーズ (educational needs) en-keyword=研究動向 (research trends) kn-keyword=研究動向 (research trends) END
