Triangulation refers to the combined application of multiple methodologies to investigate the same phenomenon, particularly in the social sciences. Theoretical inversion refers to a shift in focus from surprising outcomes to the theoretical foundations of probability. The paper introduces three types of problem-solving tasks designed to enhance one of four types of triangulations: theory triangulation. Theoretical inversion is expected to emerge through engaging in these tasks. The characteristics of the problems are as follows. Problem 1 promotes students to compare different probabilistic models of events under similar procedures. Problem 2 provides students with an opportunity to simplify an experiment by omitting steps that add no new information. Problem 3 enhances students’ ability to recognise how subtle differences in the experimental setup can affect the resulting probability. These tasks are designed to encourage students to view probabilistic reasoning as a form of modelling and to appreciate the importance of assumptions, definitions of elementary events, and clarity in procedural descriptions. en-copyright= kn-copyright= en-aut-name=UegataniYusuke en-aut-sei=Uegatani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshibashiIppo en-aut-sei=Ishibashi en-aut-mei=Ippo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakotaAya en-aut-sei=Sakota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Hiroshima University High School kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=3 en-affil=Hiroshima University High School kn-affil= en-keyword=Probability kn-keyword=Probability en-keyword=triangulation kn-keyword=triangulation en-keyword=mathematical modelling kn-keyword=mathematical modelling en-keyword=theoretical inversion kn-keyword=theoretical inversion END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=7 article-no= start-page=3143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CXCR2-Dependent Infiltration of Tumor-Associated Neutrophils Is Linked to Enhanced CD8+ T Cell Effector Function and Reduced Lung Metastasis in 4T1 Breast Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Triple-negative breast cancer (TNBC) is characterized by prominent neutrophil infiltration; however, its significance remains controversial. Here, we investigated the role of neutrophil chemoattractant receptors in TNBC progression and metastasis. In contrast to wild-type (WT), Fpr1?/?, and Fpr2?/? mice, neutrophils were almost completely absent in 4T1 tumors from Cxcr2?/? mice, indicating a dominant role for CXCR2 in the recruitment of tumor-associated neutrophils, leading us to use Cxcr2?/? mice for further studies. Primary tumor growth was comparable between WT and Cxcr2?/? mice, whereas lung metastasis was significantly increased in Cxcr2?/? mice, with reduced expression of inflammatory cytokines, chemokines and cytotoxic molecules, including granzyme B and perforin, in primary tumors and metastatic lungs of Cxcr2?/? mice. In vitro, WT, but not Cxcr2?/?, neutrophils enhanced CD8+ T cell activation, partly via ICAM-1, and directly induced tumor cell death, supporting their anti-tumor function. To assess clinical relevance, transcriptomic data were analyzed. High neutrophil infiltration combined with elevated CXCR2 expression, and to a lesser extent CXCR1 expression, was associated with improved prognosis in patients with basal-like BC that largely overlaps with TNBC. Collectively, these findings suggest that CXCR2-mediated neutrophil recruitment exerts protective, anti-tumor effects and may represent a new prognostic marker for TNBC patients. en-copyright= kn-copyright= en-aut-name=LiTiantian en-aut-sei=Li en-aut-mei=Tiantian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TianMiao en-aut-sei=Tian en-aut-mei=Miao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishidaGakushi en-aut-sei=Nishida en-aut-mei=Gakushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=neutrophils kn-keyword=neutrophils en-keyword=CD8+ T cells kn-keyword=CD8+ T cells en-keyword=chemokines kn-keyword=chemokines en-keyword=chemokine receptors kn-keyword=chemokine receptors en-keyword=tumor microenvironment kn-keyword=tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=265 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stability and distribution of dense hydrous magnesium silicates in the mantle transition zone under low water activity conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Water plays a central role in controlling the physical and chemical properties of Earth’s deep interior. It remains uncertain how water is stored in subducting slabs within the mantle transition zone, between depths of about 410 and 660 kilometers, and whether dense hydrous magnesium silicates act as major water carriers to greater depths. Here we report high-pressure and high-temperature laboratory experiments on the Mg-Si-H system at pressures of 16 and 21.5?GPa and a temperature of 1400?K to evaluate hydrous phase stability under transition zone conditions. We find that when bulk water content is below 1.22?wt%, H2O is predominantly incorporated into wadsleyite and ringwoodite rather than forming dense hydrous magnesium silicates. Because estimated water contents in subducted oceanic slabs are typically lower than one weight percent, formation of these silicates is unlikely, suggesting that the mantle transition zone may restrict large scale water transport into the lower mantle. en-copyright= kn-copyright= en-aut-name=SongYunke en-aut-sei=Song en-aut-mei=Yunke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GuoXinzhuan en-aut-sei=Guo en-aut-mei=Xinzhuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhaiKuan en-aut-sei=Zhai en-aut-mei=Kuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GuoWei en-aut-sei=Guo en-aut-mei=Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Key Laboratory of High-temperature and High-pressure Study of the Earth’s Interior, Institute of Geochemistry, Chinese Academy of Sciences kn-affil= affil-num=2 en-affil=State Key Laboratory of Critical Mineral Research and Exploration, Institute of Geochemistry, Chinese Academy of Sciences kn-affil= affil-num=3 en-affil=Key Laboratory of High-temperature and High-pressure Study of the Earth’s Interior, Institute of Geochemistry, Chinese Academy of Sciences kn-affil= affil-num=4 en-affil=State Key Laboratory of Geomicrobiology and Environmental Changes, School of Earth Sciences, China University of Geosciences (Wuhan) kn-affil= affil-num=5 en-affil=Institute for Planetary Materials, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=269 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From localized 4f electrons to anisotropic exchange interactions in ferromagnetic CeRh6Ge4 en-subtitle= kn-subtitle= en-abstract= kn-abstract=CeRh6Ge4 is a cerium-based ferromagnetic material exhibiting a quantum critical behavior under pressure. We derive effective exchange interactions, using the framework of density functional theory combined with dynamical mean-field theory. Our results reveal that the nearest-neighbor ferromagnetic interaction along the c axis is isotropic in spin space, leading to a formation of spin chains. On the other hand, the inter-chain coupling is highly anisotropic: The in-plane moment weakly interacts ferromagnetically in the a?b plane to stabilize the ferromagnetic state, whereas the z-component couples antiferromagnetically, contributing to its destabilization. The magnetic anisotropy of the interchain interactions as well as of the local 4f wavefunctions characterizes the magnetic properties underlying the ferromagnetic transition and the quantum critical behavior in CeRh6Ge4. en-copyright= kn-copyright= en-aut-name=ItokazuShoichiro en-aut-sei=Itokazu en-aut-mei=Shoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KirikoshiAkimitsu en-aut-sei=Kirikoshi en-aut-mei=Akimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JeschkeHarald O. en-aut-sei=Jeschke en-aut-mei=Harald O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukiJunya en-aut-sei=Otsuki en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3-4 article-no= start-page=706 end-page=657 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Development and Present State of Judicial Doctrine on the Speedy Trial Clause kn-title=迅速裁判条項に関する判例法理の展開と現状 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HaradaK. en-aut-sei=Harada en-aut-mei=K. kn-aut-name=原田和往 kn-aut-sei=原田 kn-aut-mei=和往 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=35 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of tubulointerstitial nephritis with infiltration of neutrophils and interleukin-17-positive cells associated with Beh?et’s disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Beh?et’s disease (BD) is a non-infectious inflammatory condition characterized by neutrophilic infiltration. In addition to primary symptoms, including oral and genital ulcers, ocular involvement, and skin lesions, BD can also affect various organs. However, renal involvement, particularly in tubulointerstitial nephritis, has rarely been described. Herein, a rare case of acute tubulointerstitial nephritis in a patient clinically diagnosed with BD is reported. The renal lesion presented with other symptoms of BD and fever, and was considered to be BD-related due to the presence of neutrophilic infiltration and its responsiveness to BD-directed therapy. Alterations in T-helper (Th) 1, Th2, and Th17 cytokine profiles are associated with BD activity. Interleukin (IL)-17 plays a central role in neutrophil activation, and recent studies have demonstrated a strong correlation between IL-17A levels and BD activity. In the present case, elevated serum IL-17A levels and infiltration of IL-17A-positive cells into the renal tissue reflected an active phase of BD and a BD-associated renal lesion. en-copyright= kn-copyright= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaKeiko en-aut-sei=Tanaka en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KubotaNatsuki en-aut-sei=Kubota en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Tubulointerstitial nephritis kn-keyword=Tubulointerstitial nephritis en-keyword=Beh?et’s disease kn-keyword=Beh?et’s disease en-keyword=Neutrophils kn-keyword=Neutrophils en-keyword=Interleukin-17 kn-keyword=Interleukin-17 en-keyword=T-helper (Th) 1/Th2/Th17 cytokines kn-keyword=T-helper (Th) 1/Th2/Th17 cytokines END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=3 article-no= start-page=e202500639 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PPy‐Coated Wire Actuators for the Micromechanostimulation of Cells: Fabrication and Characterization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular mechanotransduction signals play a crucial role in physiological and pathological conditions, including skeletal disorders. Although various systems exist to mechanically stimulate cultured cells, most are constrained by incubator incompatibility, limited physiological relevance, nonuniform stimulation, or complexity. The objective of this article is to develop and validate a compact, incubator-compatible tool capable of delivering localized and physiologically relevant mechanical stimulation to small cell populations. Here, we introduce a polypyrrole-based wire-shaped microactuator designed to induce localized mechanical stress to adjacent cells. These wire-shaped microactuators are biocompatible, easy-to-use, and compact for use within standard in vitro cell culture systems. Using a noncontact optical method, we characterize the actuation of polypyrrole-coated wires in an aqueous NaDBS electrolyte, showing radial expansion of 1.5?8??m depending on the deposited polypyrrole film thickness, comparable to cellular dimensions. Next, the actuation is confirmed to be robust and stable to use in cell culture media at physiological temperature. To evaluate biological relevance, osteoblastic KUSA-A1 cells are mechanically stimulated inside the incubator and transcriptomic changes are assessed. Mechanical stimulation resulted in upregulation of genes previously associated with mechanotransduction, including Fos and Fosb. Additionally, several uncharacterized long noncoding RNAs are differentially expressed, suggesting potential novel players in the mechanotransduction pathway. en-copyright= kn-copyright= en-aut-name=Ortega‐SantosAmaia B. en-aut-sei=Ortega‐Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Mart?nezJose G. en-aut-sei=Mart?nez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JagerEdwin W.

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

In our previous work, we constructed a non-interactive proactive secret scheme by integrating threshold homomorphic encryption (ThHE) while reducing the communication complexity to ?(?). Not only is refreshing shares important but revoking the shares of users who have left the system is also essential in practical dynamic membership scenarios. However, the previous work was insufficient for supporting explicit user revocation. This study strengthens the description of roles for authorized users and proposes a scheme to achieve non-interactive share refresh and dynamic user management. In each epoch, authorized users are classified into three roles: retain, newly join, and rejoin, and they receive a broadcast of the compact ciphertext encoding both the refresh information and the revocation instructions from the trusted center (dealer). Authorized users independently derive new shares through homomorphic computations, whereas revoked users are unable to generate new shares. Hash functions are used to bind revocation parameters to the cryptographic hashes of valid users in order to guarantee integrity during revocation, allowing for effective verification without compromising non-interactivity. Our new scheme not only extends the revocation structure but also preserves the ?(?) communication complexity. en-copyright= kn-copyright= en-aut-name=HeYixuan en-aut-sei=He en-aut-mei=Yixuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Interdisciplinary Education and Research Field, Okayama University kn-affil= en-keyword=proactive secret sharing kn-keyword=proactive secret sharing en-keyword=user revocation kn-keyword=user revocation en-keyword=threshold homomorphic encryption kn-keyword=threshold homomorphic encryption en-keyword=non-interactive kn-keyword=non-interactive END start-ver=1.4 cd-journal=joma no-vol=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=19 cd-vols= no-issue=1 article-no= start-page=42 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Biosensing method of growth diagnosis in the forced culture of strawberries ―Development of crop-identification algorithms― en-subtitle= kn-subtitle= en-abstract= kn-abstract=An image-processing algorithm for identifying individual crops is developed for labor-savings and time-series biological information collection. Information including the leaf development frequency are diagnostic indicators of strawberry growth. The algorithm is designed for drones in greenhouses that cannot acquire location information using the global navigation satellite system (GNSS). Drones fly over crop rows and sequentially assign identification numbers (IDs) to crops. Object-detection artificial intelligence (AI) is used to estimate the crop zone, and the ID is based on the crops number difference between frames. The previous misdetection rate was 1.06 %, failing to identify crops, which decreases to 0.31 % using the proposed algorithm. Furthermore, because there are no failures in consecutive frames, IDs are assigned to all crops correctly. en-copyright= kn-copyright= en-aut-name=TSUBOTAShogo en-aut-sei=TSUBOTA en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NAMBAKazuhiko en-aut-sei=NAMBA en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KASEIShota en-aut-sei=KASEI en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FUKATSUTokihiro en-aut-sei=FUKATSU en-aut-mei=Tokihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= affil-num=4 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= en-keyword=strawberry kn-keyword=strawberry en-keyword=forcing culture kn-keyword=forcing culture en-keyword=image-processing kn-keyword=image-processing en-keyword=object-detection kn-keyword=object-detection en-keyword=identification of individual crops kn-keyword=identification of individual crops en-keyword=drones kn-keyword=drones END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=JFST0004 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Numerical analysis validating the standard k-epsilon model for the kinetic energy of turbulence subjected to weak but long-lasting wind tunnel blockage acceleration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the effect of weak but prolonged mean flow accelerations, such as those observed in wind tunnel blockage acceleration, on free-stream turbulence. Specifically, this research aims to validate a model previously developed based on the k-epsilon model. To test this model, the study focuses on scenarios where the turbulence under acceleration is steady and isotropic, since the model suggests that this type of acceleration has no effect on the turbulent kinetic energy. To examine this suggestion, the turbulence within a periodic box was analyzed using large-eddy simulation (LES) based on the conventional Smagorinsky model framework. The numerical analysis is based on a method that conserves velocity fluctuation intensities. The results show that while high rate of acceleration deviates turbulent kinetic energy, low rate acceleration has hardly any effect on turbulent kinetic energy, enstrophy, pressure fluctuation, relative pressure fluctuation intensity, and higher-order statistics of a velocity fluctuation. These results validate the accuracy of the model proposed in the previous studies. These results were obtained by focusing on differences in Reynolds numbers and the spatial scale of the forcing. en-copyright= kn-copyright= en-aut-name=ONOAkira en-aut-sei=ONO en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Homogeneous turbulence kn-keyword=Homogeneous turbulence en-keyword=K-epsilon model kn-keyword=K-epsilon model en-keyword=Wind tunnel blockage kn-keyword=Wind tunnel blockage END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=110 end-page=118 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trend of adjusted antenatal care visits on pregnant women and neonatal during the COVID-19 pandemic: Findings from a three districts survey in 2021 en-subtitle= kn-subtitle= en-abstract=Upaya pengembangan kesehatan berkelanjutan di tengah wabah penyakit menular seperti COVID-19 memerlukan sistem kesehatan ibu yang tangguh.

With cases rising globally and across Asia, Indonesia faces significant disruptions in essential services. A critical research gap exist in utilizing adjusted time-series analysis to isolated pandemic impact from seasonal variation in urban Indonesia. This study evaluates trends in antenatal care (ANC) visits (January 2019?December 2020) at three Community Health Centres in Makassar: Bara-Baraya, Jongaya and Batua using Interrupted Time Series (ITS) analysis. Findings reveal a significant decline in visits during the second and third quarters of 2020, primarily due to transmission fears. We suggest integration of telemedicine and home visits to maintain continuity of care. Although focused on urban Makassar, these results are an important reference for health and offer applicable solutions for other developing countries facing resource constraints. This study emphasizes the need for inclusive prevention strategies to protect maternal health in urban and rural areas in low- to middle-income countries during systemic health crises. en-copyright= kn-copyright= en-aut-name=IbrahimJuliani en-aut-sei=Ibrahim en-aut-mei=Juliani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IbrahimSukaeni en-aut-sei=Ibrahim en-aut-mei=Sukaeni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Departement of Public Health, Faculty of Medicine and Health Science, Universitas Muhammadiyah Makassar kn-affil= affil-num=2 en-affil=Nursing of Department, Graduate School of Health Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Bosowa University kn-affil= en-keyword=antenatal care kn-keyword=antenatal care en-keyword=covid-19 kn-keyword=covid-19 en-keyword=interrupted time series kn-keyword=interrupted time series en-keyword=maternal health kn-keyword=maternal health en-keyword=neonatal birth kn-keyword=neonatal birth END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=6 article-no= start-page=657 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adolescent screen use in the pre-internet era and subsequent health and well-being: an outcome-wide longitudinal study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study used data from the National Longitudinal Study of Adolescent to Adult Health (Add Health, N?=?11,054) to assess whether increases in screen-based leisure during adolescence (Wave II, from 1996) predicted adult well-being (Wave IV, from 2008-09), adjusting for a wide range of covariates (Wave I, from 1995). Using an outcome-wide analytic approach, we examined associations between screen time and 38 adult outcomes, adjusting for prior screen time, values of most outcomes, and confounders. Most associations were null. Modest evidence was found for links between screen time (continuous) and reduced sense of control, illicit drug use, and allostatic load. High screen time (14 h/week) or more also showed weak associations with lower depression and preventive care use. Because the data predate widespread internet use, the findings help establish a baseline for the long-term effects of non-internet screen activities, which appeared to behave had limited impact on adult health and well-being. en-copyright= kn-copyright= en-aut-name=de la Rosa Fern?ndez-PachecoPedro Antonio en-aut-sei=de la Rosa Fern?ndez-Pacheco en-aut-mei=Pedro Antonio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WilkinsonRenae en-aut-sei=Wilkinson en-aut-mei=Renae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CowdenRichard G. en-aut-sei=Cowden en-aut-mei=Richard G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChenYing en-aut-sei=Chen en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CaseBrendan en-aut-sei=Case en-aut-mei=Brendan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=VanderWeeleTyler J. en-aut-sei=VanderWeele en-aut-mei=Tyler J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Youth in Transition, Institute for Culture and Society, Universidad de Navarra kn-affil= affil-num=2 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=3 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=4 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=5 en-affil=Human Flourishing Program, Institute for Quantitative Social Science, Harvard University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Leisure kn-keyword=Leisure en-keyword=Television kn-keyword=Television en-keyword=Outcome-wide epidemiology kn-keyword=Outcome-wide epidemiology en-keyword=Video games kn-keyword=Video games en-keyword=Adolescence kn-keyword=Adolescence en-keyword=Well-being kn-keyword=Well-being END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue= article-no= start-page=102828 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of FTase inhibitors inspired by the structures of andrastins en-subtitle= kn-subtitle= en-abstract= kn-abstract=We designed and synthesized structurally simple farnesyl transferase (FTase) inhibitors (1a?1d) by leveraging andrastin, a natural product with FTase inhibitory activity. 1a?1d possess a cyclopentane-1,3-dione core, which is critical for FTase recognition; a farnesyl moiety, which is a simplified motif of A to C rings of andrastin; and a carboxylic acid or methoxycarbonyl group, which enables multipoint hydrogen bonding interactions with FTase. Competitive inhibition experiments revealed that 1d has the most potent FTase inhibitory activity.

This study evaluates the direct impact of ECC and its relationship to profitability (ROA) using panel data of Japanese companies from 2010 to 2022 and Pooled OLS regression models. The results demonstrate the risk-mitigating function of sustainability investments by showing that, although independent ECC have little direct significance, their interaction with firm profitability dramatically lowers earnings volatility and leverage instability. These findings underscore the economic value of environmental strategies, suggesting that incorporating profitability considerations into sustainability practices enhances operational stability and reduces risk exposure. To help policymakers, investors, and corporate managers strike a balance between sustainability and financial performance, this study contributes to the growing body of research on the relationship between the environment and finance. en-copyright= kn-copyright= en-aut-name=NAZIRYUSRA en-aut-sei=NAZIR en-aut-mei=YUSRA kn-aut-name=ナジールユスラ kn-aut-sei=ナジール kn-aut-mei=ユスラ aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 en-keyword=Environmental Accounting kn-keyword=Environmental Accounting en-keyword=Environmental Conservation Costs kn-keyword=Environmental Conservation Costs en-keyword=Firm Risk kn-keyword=Firm Risk en-keyword=Earnings Volatility kn-keyword=Earnings Volatility en-keyword=ESG kn-keyword=ESG en-keyword=and Risk Management Leverage Ratio kn-keyword=and Risk Management Leverage Ratio en-keyword=Sustainability kn-keyword=Sustainability en-keyword=Panel Data kn-keyword=Panel Data en-keyword=Japanese Companies kn-keyword=Japanese Companies END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=93 end-page=109 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental Conservation Costs and Operational Efficiency: Evidence from Japanese Manufacturing Firms en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study investigates whether environmental conservation costs (ECC) support the operational effectiveness and financial stability of Japanese manufacturing firms. Using a balanced panel of 128 non-financial companies listed on the Tokyo Stock Exchange from 2010 to 2022, we manually collected firm-level ECC data based on the Ministry of the Environment, Japan's guidelines from sustainability reports and matched them with financial data from Compustat Global/S&P Capital IQ. Applying pooled ordinary least squares regression with firm-level clustered standard errors and winsorized variables, we examine two aspects of performance as measures of operating efficiency and profitability: asset turnover and profit margin. The results show that ECC is positively associated with asset turnover and profit margin, and that the effect is stronger in more profitable companies, substantiating the Resource-Based View that green practices generate competitiveness. These findings contribute to sustainability finance research by going beyond perceptual measures of environmental, social, and governance ratings, and measuring actual firm-level spending on environmental activities, thereby providing more nuanced insights into how environmental practices translate into actual financial performance. This study offers clear managerial and policy implications by showing that transparent environmental conservation costs improve disclosure quality and serve as a measure of improved efficiency and profitability. en-copyright= kn-copyright= en-aut-name=NazirYusra en-aut-sei=Nazir en-aut-mei=Yusra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TennojiyaTatsumasa en-aut-sei=Tennojiya en-aut-mei=Tatsumasa kn-aut-name=天王寺谷達将 kn-aut-sei=天王寺谷 kn-aut-mei=達将 aut-affil-num=2 ORCID= affil-num=1 en-affil=Doctoral student at Graduate school of humanities and social sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of humanities and social sciences, Okayama University kn-affil= en-keyword=Environmental Accounting kn-keyword=Environmental Accounting en-keyword=Environmental Conservation Cost, Operating Efficiency kn-keyword=Environmental Conservation Cost, Operating Efficiency en-keyword=Profitability kn-keyword=Profitability en-keyword=Asset Turnover kn-keyword=Asset Turnover en-keyword=Sustainability kn-keyword=Sustainability en-keyword=Japanese Manufacturing Companies kn-keyword=Japanese Manufacturing Companies en-keyword=Resource-Based View kn-keyword=Resource-Based View END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue= article-no= start-page=101798 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alcohol consumption, smoking, and the implications of their cessations for field carcinogenesis in the esophagus: a 10-year prospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Alcohol and tobacco are established carcinogens, which promote field carcinogenesis for esophageal squamous cell carcinoma (ESCC). This study aimed to evaluate the long-term effects of alcohol and tobacco cessations, and background mucosal status, on risk for metachronous ESCC (mESCC) after endoscopic resection (ER).
Methods This was a multicentre prospective cohort study of patients with intramucosal ESCC treated by ER. All participants received structured education on cessation, and underwent regular endoscopic surveillance. Patients were stratified by Lugol-voiding lesion (LVL) grade (A: none, B: 1?9, C: ?10). The impacts of alcohol and smoking cessation on field carcinogenesis were assessed.
Findings Among 331 enrolled patients, the median follow-up was 120 months (range: 1.3?176.9). The cumulative incidences of mESCC were 10.4%, 27.2%, and 61.8% in grades A, B, and C, respectively. An increment of 1 unit (22 g ethanol) of alcohol consumption and higher LVL grade independently increased the risk for mESCC. Alcohol or smoking cessation reduced this risk (hazard ratio [HR] 0.52, 95% confidence interval [CI]: 0.31?0.88; HR 0.44, 95% CI: 0.25?0.78, respectively), and combined cessation had the greatest impact (HR 0.21, 95% CI: 0.07?0.65). Complete cessation, rather than partial reduction, was necessary to achieve meaningful risk reduction.
Interpretation Alcohol and tobacco exposure, and a large number of LVL, are major determinants of mESCC. Complete cessation markedly reduces risk, underscoring the importance of behavioural interventions for secondary prevention of field carcinogenesis after ER. en-copyright= kn-copyright=

kinase inhibitors as monotherapy in rheumatoid arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Sarilumab (SAR), an interleukin-6 receptor inhibitor (IL-6Ri), and Janus kinase inhibitors (JAKi) are approved options for rheumatoid arthritis (RA) when methotrexate (MTX) cannot be used. Real-world evidence for MTX-free monotherapy remains limited.
Methods: We conducted a multicenter retrospective cohort study of RA patients receiving SAR or JAKi as MTX-free monotherapy. To reduce confounding, 1:1 propensity score matching was performed in the overall cohort (n?=?252, 126 per group) and separately within treatment-line strata: Phase 2 first-line biologic/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs: 45 per group), Phase 3 second-line b/tsDMARDs (53 per group), and Phase 3???third-line b/tsDMARDs (47 per group). Outcomes over 12 months included drug retention, change in Clinical Disease Activity Index (CDAI), glucocorticoid (GC) tapering and discontinuation, low disease activity (LDA, CDAI???10), and safety profiles. Predictors of LDA were evaluated with logistic regression. This multicenter real-world.
Results: Across matched strata by prior b/tsDMARDs, retention and CDAI change did not differ significantly between SAR and JAKi through 12 months. When classified by cause, adverse events (AEs)-related discontinuation was higher with JAKi, yielding lower AE-specific retention. Both groups demonstrated GC sparing overtime, with a greater increase in GC discontinuation for SAR than for JAKi in Phase 2. Baseline predictors of achieving LDA at 12 months included higher C-reactive protein (CRP) and platelet count (Plt) in both groups, with additional associations of younger age and lower hemoglobin (Hb) in the SAR. In safety analyses, overall AEs were less frequent with SAR than with JAKi, driven by lower risks of infection including herpes zoster, while other categories were similarly infrequent.
Conclusion: SAR and JAKi showed no statistically significant differences in 12-month retention or disease control in MTX-free monotherapy settings. Higher CRP and Plt with lower Hb, particularly in younger patients, identified better response to SAR and support biomarker guided selection between IL-6Ri and JAKi. In Phase 2, GC discontinuation with SAR suggests a practical strategy to reduce AEs while maintaining efficacy. Prospective studies should validate these findings and define actionable thresholds. en-copyright= kn-copyright= en-aut-name=NozakiYuji en-aut-sei=Nozaki en-aut-mei=Yuji kn-aut-name= kn-aut-sei=

kn-article= en-subject= kn-subject= en-title= kn-title=Prescription Support Practice for Pharmacy Students: Pre-Post Educational Intervention Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In the field of team-based care, pharmacists are vital for optimizing medication therapy. However, many medical professionals lack the opportunity to learn how to propose prescription changes with precision.
Objective: This study aimed to address this knowledge gap by developing and assessing a new educational program for pharmacy students focused on prescription support and interprofessional collaboration.
Methods: We recruited 191 fifth-year pharmaceutical students during the 2022‐2024 academic years. The program featured a 7-day intensive curriculum that included learning how to assist with prescriptions, analyzing clinical data, and engaging in role-playing exercises. A web-based questionnaire and a paper test were used to evaluate students’ awareness and knowledge both before and after the program. Statistical analyses were performed to verify the significance of changes; we utilized the Wilcoxon signed-rank test for the ordinal data derived from the specific behavioral objectives and 2-tailed paired t tests for the interval data from the knowledge tests. The magnitude of change was quantified using r for Wilcoxon tests and Cohen dz for 2-tailed t tests, with 95% CI calculated to ensure the stability and reliability of the observed results.
Results: Analysis of the primary outcome specific behavioral objectives revealed statistically significant effects across all items (Wilcoxon signed-rank test; P<.001). Effect sizes (r=0.505‐0.835) ranged from moderate to large, with particularly large effects observed in identifying contents issue (r=0.835, 95% CI 0.126-0.330; P<.001). Knowledge test scores showed significant improvement in the following 3 subjects: pharmacology (r=?0.504, 95% CI ?0.215 to 0.127; P<.001), organic chemistry (r=0.254, 95% CI ?0.148 to ?0.193; P=.004), and communication (r=0.221, 95% CI ?0.151 to ?0.190; P=.01). No significant changes were observed in pathology or pharmacokinetics.
Conclusions: This program provides strong evidence that practical, hands-on learning with hospital pharmacists helps improve pharmacy students’ professional skills and optimize pharmaceutical therapies in interprofessional care. By teaching pharmacists to effectively propose prescription changes, the program equips them to become integral members of interprofessional care, ultimately leading to optimized pharmaceutical care for patients. en-copyright= kn-copyright= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagiKenta en-aut-sei=Yagi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HigashionnaTsukasa en-aut-sei=Higashionna en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiShimon en-aut-sei=Takahashi en-aut-mei=Shimon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShinomiyaKazuaki en-aut-sei=Shinomiya en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NiimuraTakahiro en-aut-sei=Niimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GodaMitsuhiro en-aut-sei=Goda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawadaKei en-aut-sei=Kawada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshizawaKeisuke en-aut-sei=Ishizawa en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=2 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=6 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmaceutical Care and Clinical Pharmacy, Tokushima Bunri University kn-affil= affil-num=8 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=10 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=11 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= en-keyword=academic detailing kn-keyword=academic detailing en-keyword=pharmaceutical clinical practice kn-keyword=pharmaceutical clinical practice en-keyword=prescription support kn-keyword=prescription support en-keyword=professional education kn-keyword=professional education en-keyword=Interprofessional care kn-keyword=Interprofessional care END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=3 article-no= start-page=e198959 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagen-binding C-type natriuretic peptide enhances chondrogenesis and osteogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=C-type natriuretic peptide (CNP) is known to promote chondrocyte proliferation and bone formation; however, CNP’s extremely short half-life necessitates continuous intravascular administration to achieve bone-lengthening effects. Vosoritide, a CNP analog designed for resistance to neutral endopeptidase, allows for once-daily administration. Nonetheless, it distributes systemically rather than localizing to target tissues, which may result in adverse effects such as hypotension. To enhance local drug delivery and therapeutic efficacy, we developed a potentially novel synthetic protein by fusing a collagen-binding domain (CBD) to CNP, termed CBD-CNP. This fusion protein exhibited stability under heat conditions and retained the collagen-binding ability and bioactivity as CNP. CBD-CNP localized to articular cartilage in fetal murine tibiae and promoted bone elongation. Spatial transcriptomic analysis revealed that the upregulation of chondromodulin expression may contribute to its therapeutic effects. Treatment of CBD-CNP mixed with collagen powder to a fracture site of a mouse model increased bone mineral content and bone volume compared with CNP-22. Intraarticular injection of CBD-CNP to a mouse model of knee osteoarthritis suppressed subchondral bone thickening. By addressing the limitations of CNP’s rapid degeneration, CBD-CNP leverages its collagen-binding capacity to achieve targeted, sustained delivery in collagen-rich tissues, offering a promising strategy for enhancing chondrogenesis and osteogenesis. en-copyright= kn-copyright= en-aut-name=HiraiKenta en-aut-sei=Hirai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawamuraKenta en-aut-sei=Sawamura en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EsakiRyusaku en-aut-sei=Esaki en-aut-mei=Ryusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkushaYuka en-aut-sei=Okusha en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaEriko en-aut-sei=Aoyama en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoHiroki en-aut-sei=Saito en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaKentaro en-aut-sei=Uchida en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MimaTakehiko en-aut-sei=Mima en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ImagamaShiro en-aut-sei=Imagama en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsushitaMasaki en-aut-sei=Matsushita en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HosonoYasuyuki en-aut-sei=Hosono en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=9 en-affil=Department of Medical Technology, Faculty of Health Sciences, Ehime Prefectural University of Health Sciences kn-affil= affil-num=10 en-affil=Department of Biochemistry and Molecular DentistryBacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-world six-month outcomes after switching from aflibercept 2 mg to aflibercept 8 mg for neovascular age-related macular degeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To investigate 6-month outcomes in eyes with neovascular age-related macular degeneration (nAMD) switched from intravitreal aflibercept 2 mg to intravitreal aflibercept 8 mg.
Study design Retrospective observational study.
Methods We reviewed records of consecutive nAMD eyes switched from aflibercept 2 mg to 8 mg. In eyes continuing aflibercept 8 mg, best-corrected visual acuity (BCVA), treatment intervals, and anatomical/exudative parameters were evaluated at 6 months. In eyes that could not continue, reasons for discontinuation were examined.
Results Forty-four eyes from 44 patients were included. At 6 months, 35 eyes (79.5%) continued and 9 (20.5%) discontinued aflibercept 8 mg. Discontinuing eyes had significantly shorter pre-switch treatment intervals and more frequent prior therapies than continuing eyes. In the continuation group, BCVA remained stable (median 0.05 to 0.00 logMAR, P = 0.351), while the treatment interval was significantly extended (median 7.0 to 9.0 weeks, P < 0.001). Central retinal thickness and pigment epithelial detachment height decreased significantly (P = 0.035 and P = 0.021, respectively). The proportion of eyes with subretinal fluid significantly decreased from 74.3 to 37.1% (P = 0.003). Of the discontinuations, 4 were due to worsening exudation and 5 to inability to extend to ?8 weeks as required by labeling. No intraocular inflammation or serious adverse events occurred.
Conclusions Switching to aflibercept 8?mg achieved anatomical improvements and longer treatment intervals in ~80% of nAMD cases, suggesting it may be a useful alternative to aflibercept 2 mg. However, continuation may be difficult in refractory cases requiring frequent injections before switching. en-copyright= kn-copyright= en-aut-name=KindoHiroya en-aut-sei=Kindo en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HosokawaMio Morizane en-aut-sei=Hosokawa en-aut-mei=Mio Morizane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HayashiJunko en-aut-sei=Hayashi en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Aflibercept 8 mg kn-keyword=Aflibercept 8 mg en-keyword=Neovascular age-related macular degeneration kn-keyword=Neovascular age-related macular degeneration en-keyword=Treat-and-extend kn-keyword=Treat-and-extend en-keyword=Switching kn-keyword=Switching en-keyword=Treatment interval kn-keyword=Treatment interval END start-ver=1.4 cd-journal=joma no-vol=411 cd-vols= no-issue=1 article-no= start-page=21 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical outcomes and patient selection in nonagenarians with colon cancer: a comparative multi-institutional study of laparoscopic and open approaches en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The appropriate surgical approach for colon cancer (CC) in nonagenarian patients remains a subject of clinical debate. This study aimed to compare the short-term outcomes of laparoscopic (Lap) versus open (Open) surgery in patients aged???90 years with resectable colon cancer.
Methods This multi-institutional retrospective cohort study included oldest-old patientswith pathological Stage II/III CC who underwent elective surgery at 15 hospitals between 2011 and 2022. Patients with rectal cancer, Stage 0/I/IV disease, or emergency surgery were excluded. To address selection bias, inverse-probability-weighted regression adjustment and stabilized inverse probability of treatment weighting (sIPTW) were applied. The primary outcome was postoperative complications; secondary outcomes included overall survival (OS).
Results Median age was 92 years in both groups. Before adjustment, the Lap group had a higher proportion of female patients (p?=?0.038) and lower ASA scores (p?=?0.01). Laparoscopic surgery was associated with a significantly longer operative time (220 vs. 171 min, p?=?0.046) but less intraoperative blood loss (10 vs. 78 mL, p? Conclusion Both laparoscopic and open surgery are feasible options for selected nonagenarians with colon cancer. Laparoscopic surgery may offer benefits in terms of reduced blood loss and shorter hospitalization, despite longer operative times. Careful patient selection considering frailty and comorbidities is essential in determining the most appropriate surgical approach. en-copyright= kn-copyright= en-aut-name=ShojiRyohei en-aut-sei=Shoji

C-reactive protein as a predictive biomarker for postoperative complications following robot-assisted surgery for rectal cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=This retrospective cohort study aimed to assess the predictive value of early postoperative C-reactive protein (CRP) levels for complications following robot-assisted rectal surgery (RARS) for rectal cancer. We analyzed data from 117 consecutive patients who underwent elective RARS at Okayama University Hospital between September 2020 and January 2025. Serum CRP levels were routinely measured preoperatively and on postoperative days (POD) 1 and 4. The primary outcome was the occurrence of any postoperative complication within 30 days, classified according to the Clavien?Dindo grading system. Postoperative complications were observed in 26 patients, representing 22.2% of the cohort. Univariate analysis revealed that several factors were significantly associated with complications, including older age, higher ASA score, neoadjuvant therapy, stoma creation, prolonged operative time, and elevated CRP levels on POD1 and POD4. Notably, multivariate logistic regression analysis identified POD1 CRP as a robust independent predictor of overall postoperative complications (adjusted odds ratio 0.77, 95% confidence interval (CI) [0.63?0.93], p? Methods: This cross-sectional multicentre study surveyed 133 adults with DS (mean age 50.1?years) residing in 45 welfare facilities across Japan in 2019. Dementia was diagnosed by a consensus panel of physicians using established criteria (DSM-5, ICD-10, DC-LD) after comprehensive assessments, including the Japanese version of the Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID-J). Logistic regression analysis was performed to identify factors independently associated with dementia.
Results: Forty-six participants (34.6%) were diagnosed with dementia. The prevalence rose sharply with age: 0% in their 30s, 30.8% in their 40s, 31.6% in their 50s and 65.5% in their 60s. After adjusting for covariates, older age, female sex, dyslipidaemia and visual impairment were independently associated with dementia.
Conclusions: This study, the largest of its kind in Asia, confirms a high prevalence of dementia in institutionalized Japanese adults with DS. Crucially, this study is the first to identify dyslipidaemia and visual impairment as independent and potentially modifiable risk factors in this population. These findings highlight tangible targets for clinical interventions aimed at mitigating dementia risk in people with DS. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueTomokazu en-aut-sei=Inoue en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KurozumiTaku en-aut-sei=Kurozumi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwanoRyozo en-aut-sei=Kuwano en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuemitsuShigeru en-aut-sei=Suemitsu en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=4 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=7 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99825 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250618 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stimulatory and inhibitory G-protein signaling relays drive cAMP accumulation for timely metamorphosis in the chordate Ciona en-subtitle= kn-subtitle= en-abstract= kn-abstract=Larvae of the ascidian Ciona initiate metamorphosis tens of minutes after adhesion to a substratum via their adhesive organ. The gap between adhesion and metamorphosis initiation is suggested to ensure the rigidity of adhesion, allowing Ciona to maintain settlement after losing locomotive activity through metamorphosis. The mechanism producing the gap is unknown. Here, by combining gene functional analyses, pharmacological analyses, and live imaging, we propose that the gap represents the time required for sufficient cyclic adenosine monophosphate (cAMP) accumulation to trigger metamorphosis. Not only the Gs pathway but also the Gi and Gq pathways are involved in the initiation of metamorphosis in the downstream signaling cascade of the neurotransmitter GABA, the known initiator of Ciona metamorphosis. The mutual crosstalk of stimulatory and inhibitory G-proteins functions as the accelerator and brake for cAMP production, ensuring the faithful initiation of metamorphosis at an appropriate time and in the right situation. en-copyright= kn-copyright= en-aut-name=HozumiAkiko en-aut-sei=Hozumi en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TotsukaNozomu M en-aut-sei=Totsuka en-aut-mei=Nozomu M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoderaArata en-aut-sei=Onodera en-aut-mei=Arata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYanbin en-aut-sei=Wang en-aut-mei=Yanbin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiraishiAkira en-aut-sei=Shiraishi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatakeHonoo en-aut-sei=Satake en-aut-mei=Honoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HorieTakeo en-aut-sei=Horie en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HottaKohji en-aut-sei=Hotta en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SasakuraYasunori en-aut-sei=Sasakura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=2 en-affil=Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University kn-affil= affil-num=3 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=4 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=5 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=6 en-affil=Bioorganic Research Institute, Suntory Foundation for Life Sciences kn-affil= affil-num=7 en-affil=Bioorganic Research Institute, Suntory Foundation for Life Sciences kn-affil= affil-num=8 en-affil=Laboratory for Single-cell Neurobiology, Graduate School of Frontier Biosciences, Osaka University kn-affil= affil-num=9 en-affil=Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University kn-affil= affil-num=10 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=1 article-no= start-page=e70089 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lifestyle Factors and Current Alcohol Consumption Among Japanese Adolescents During the COVID-19 Pandemic: A Nationwide Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The COVID-19 pandemic may have influenced drinking behaviors in minors by disrupting daily routines and increasing psychosocial stress, although alcohol use among Japanese adolescents has declined in recent years. We aimed to clarify the relationships between current alcohol consumption and lifestyle factors during the COVID-19 pandemic based on a nationwide cross-sectional survey.
Methods: This cross-sectional study analyzed data from the 2021 Lifestyle Survey of Adolescents, a nationwide survey conducted in Japan during the COVID-19 pandemic. A total of 15?549 junior and senior high school students (7645 boys and 7904 girls) were included. Current alcohol consumption was defined as drinking on at least 1?day in the past 30?days. Multivariable logistic regression analyses were used to examine associations between current alcohol consumption and lifestyle factors, including irregular sleep patterns, irregular dietary habits, and increased screen time. Sex-stratified analyses and interaction tests were also performed.
Results: The overall prevalence of current alcohol consumption was 2.1%, with slightly higher rates among boys (2.2%) than girls (2.0%). Current alcohol consumption was significantly associated with irregular sleep patterns (odds ratio [OR]?=?1.51; 95% confidence interval [CI], 1.17?1.95) and irregular dietary habits (OR?=?1.68; 95% CI, 1.18?2.40). An association with increased screen time was also observed (OR?=?1.29; 95% CI, 1.00?1.69), particularly among boys. A significant interaction by sex was detected for irregular sleep patterns (p for interaction?=?0.013).
Conclusions: Alcohol consumption among Japanese adolescents was associated with irregular sleep and dietary habits and, among boys, with increased screen time. These findings highlight the importance of promoting regular routines and addressing lifestyle-related risks to prevent current alcohol consumption among adolescents during public health crises.

condition comparable to Good's syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Good's syndrome (GS) is a rare immunodeficiency disorder associated with thymoma, characterized by hypogammaglobulinemia and recurrent infections; however, its clinical significance in thymoma-associated myasthenia gravis (TAMG) remains unclear. We retrospectively reviewed 30 patients with TAMG admitted to our center between January 2010 and March 2022. We defined GS-like immunodeficiency as serum IgG below the institutional cutoff of 861 mg/dL and a history of two or more infections requiring antimicrobial treatment; 11 patients (36.7%) met this definition. Compared with the remaining patients, the GS-like group had higher incidences of malignancy (45.5% vs. 5.3%, p = 0.016) and autoimmune diseases other than MG (36.4% vs. 5.3%, p = 0.047), lower peripheral lymphocyte counts (median 1100/μL vs. 2200/μL, p = 0.0051), and more frequent airflow obstruction defined by one second to forced vital capacity ratio of less than 70% (60.0% vs. 5.3%, p = 0.0026). Five deaths occurred in the GS-like group, and none in the other; median survival from the first antimicrobial-treated infection was 5.0 years. These findings imply that TAMG patients with GS-like immunodeficiency have a worse prognosis, underscoring the need for close monitoring and timely adjustments of MG management.

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

A multiple-treatments design was utilized to determine if the projected character prompt strategy was the most effective, followed by the character puppet prompt and the marker prompt. Results indicated that the marker prompt strategy and the projected character strategy were equally effective in helping the student to acquire table-wiping skills and more effective than the character puppet prompt strategy. However, the projected character prompt strategy elicited the most positive expressions and the fewest refusal behaviors. In contrast, the marker prompt strategy induced the fewest positive express ions and the most refusa l behaviors. en-copyright= kn-copyright= en-aut-name=MatsushitaYoshimasa en-aut-sei=Matsushita en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhtakeYoshihisa en-aut-sei=Ohtake en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=The Joint Graduate School in Science of School Education (Doctor’s Course), Hyogo University of Teacher Education kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= en-keyword=stimulus prompt kn-keyword=stimulus prompt en-keyword=cleaning kn-keyword=cleaning en-keyword=autism spectrum disorder kn-keyword=autism spectrum disorder en-keyword=intellectual disability kn-keyword=intellectual disability en-keyword=projected character kn-keyword=projected character END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=25-00095 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Examining OpenFOAM-based LES analysis in terms of inviscid energy conservation and viscous turbulence decay en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study examines an OpenFOAM-based LES analysis from the viewpoints of inviscid energy conservation and viscous turbulence decay. The Smagorinsky model is employed as the sub-grid scale (SGS) model, and a two-dimensional periodic analytical solution and a three-dimensional periodic Taylor-Green vortex (TGV) are employed to represent inviscid flows. The analytical relationship for the kinetic energy K, dK/dt = 0, with t as the dimensionless time, is utilized to validate the OpenFOAM results. For the viscous flow case, the TGV flow in a three-dimensional periodic cubic domain is adopted, and its turbulence kinetic energy distribution is compared with that obtained by a spectral method to examine the analysis. The OpenFOAM-based analysis exhibits energy conservation error in flows that should ideally conserve energy. For the two-dimensional flow, this error decreases with increasing grid resolution N. However, in the three-dimensional flow, the error does not improve even with higher N. In the three-dimensional TGV flow, the turbulence kinetic energy predicted by OpenFOAM exhibits a strong agreement with that from the spectral method when a standard constant value of the Smagorinsky model is employed and the mesh is sufficiently refined. Conversely, for a condition of relatively coarse mesh, the decay characteristics of turbulent kinetic energy deviate from those of the spectral method, and a higher constant value of the Smagorinsky model than the default value becomes necessary to reproduce comparable results. These results suggests that even in LES simulations where highly accurate conservation laws are not satisfied, adjusting the model constants so that the predicted values match experimental or numerical reference data can improve the apparent reliability of the turbulent kinetic energy in the decaying turbulence. en-copyright= kn-copyright= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Numerical simulation kn-keyword=Numerical simulation en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Energy conservation kn-keyword=Energy conservation en-keyword=Decaying turbulence kn-keyword=Decaying turbulence END start-ver=1.4 cd-journal=joma no-vol=183 cd-vols= no-issue= article-no= start-page=111902 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Monitoring postharvest water loss in eggplants (Solanum melongena L.) using UV-induced fluorescence imaging and multivariate analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eggplant (Solanum melongena L.) is susceptible to significant postharvest losses primarily due to water loss during storage, which affects market quality by causing texture and glossiness degradation. We investigated whether UV-induced fluorescence imaging and EEM (Excitation-Emission Matrix) fluorescence spectroscopy can non-destructively monitor WL under four storage regimes (10 °C/95 % RH, 20 °C/95 % RH, 20 °C/75 % RH, 10 °C/75 % RH). EEMs exhibited three regions; a 365/420 nm blue emission increased most under warm, low-humidity storage and is consistent with phenolic/lignin-related fluorescence. Side-view fluorescence (FL) images showed progressive blue-white emission and surface textural changes that tracked gravimetric water loss (WL). A PLSR model using combined color and texture features from FL and reflectance (CL) images achieved R2CV = 0.88 (RMSECV = 3.47 %) with only six features. To test a minimal predictor, we fit an Analysis of Covariance (ANCOVA) using Day-1 FL MeanBlue as a covariate and storage category as a factor with Leave One Out Cross-validation (LOOCV); this forecasted cumulative WL with R2LOOCV = 0.92 and MAE = 1.88 %. Importantly, this ANCOVA model using Day-1 blue-band fluorescence as a covariate was predictive only under 20 °C/75 % RH; under the other conditions, its contribution was weak. Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) models achieved accuracies of 94.4 % and 85.2 %, respectively, in differentiating storage conditions. These results support low-cost FL imaging as a practical tool to monitor WL and storage stress. en-copyright= kn-copyright= en-aut-name=RotichVincent en-aut-sei=Rotich en-aut-mei=Vincent kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GaoTianqi en-aut-sei=Gao en-aut-mei=Tianqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PrempreePanintorn en-aut-sei=Prempree en-aut-mei=Panintorn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayashiTakahiro en-aut-sei=Hayashi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NambaKazuhiko en-aut-sei=Namba en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MontaMitsuji en-aut-sei=Monta en-aut-mei=Mitsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishimotoMotomi en-aut-sei=Nishimoto en-aut-mei=Motomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoNaoshi en-aut-sei=Kondo en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=3 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Technology and Innovation Center, Daikin Industries, Ltd. kn-affil= affil-num=8 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=Eggplant kn-keyword=Eggplant en-keyword=Fluorescence spectroscopy kn-keyword=Fluorescence spectroscopy en-keyword=UV-Induced imaging kn-keyword=UV-Induced imaging en-keyword=Water loss kn-keyword=Water loss en-keyword=Postharvest quality kn-keyword=Postharvest quality en-keyword=Non-destructive assessment kn-keyword=Non-destructive assessment END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safety and feasibility of D3 lymph node dissection in oldest-old patients undergoing colorectal cancer surgery: a multi-institutional, retrospective analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Colorectal cancer (CRC) is a significant health burden, with lymph node dissection (LND) playing a critical role in staging and guiding treatment. However, the optimal extent of LND for the oldest-old population (aged???90 years) remains undefined because of insufficient targeted clinical data. This study aimed to compare the short-term outcomes of D3 versus non-D3 LND in Stage II?III CRC in oldest-old patients.
Methods This retrospective cohort study utilized data from the Setouchi Colorectal Neoplasm Registration database, including 282 oldest-old patients with CRC treated between 2011 and 2022. Patients were stratified into D3 and non-D3 LND groups, with inverse-probability-weighted regression adjustment implemented to address potential confounding factors. Postoperative complications and hospital stays were analyzed using regression models and descriptive statistics.

kn-subtitle= en-abstract= kn-abstract=Primary congenital glaucoma is a rare congenital disease with a genetic background that shows high intraocular pressure due to ocular outflow anomalies. Retinitis pigmentosa is a predominant form of inherited retinal disorders. In this study, we present the case of a patient with primary congenital glaucoma in association with retinitis pigmentosa. A four-month-old female baby was brought to the emergency department due to corneal opacity in the left eye. The intraocular pressure measured by a hand-held applanation tonometer was 40 mmHg in the right eye and 36 mmHg in the left eye. She was otherwise healthy and diagnosed with primary congenital glaucoma. She immediately underwent trabeculotomy ab externo in both eyes under general anesthesia, and the intraocular pressure was lowered to 15 mmHg in the right eye and 12 mmHg in the left eye three weeks later. At the age of nine months, she was found to have retinal degeneration along the upper and lower vascular arcades of the fundus in both eyes and was diagnosed with retinitis pigmentosa. At the age of one year and 10 months, the visual acuity was measured at 0.2 in the right eye and 0.2 in the left eye for the first time by a preferential looking procedure. The intraocular pressure was 9 mmHg in both eyes under sedation, and she did not use any topical medication. At the age of three years and three months, the uncorrected visual acuity and best-corrected visual acuity with myopic astigmatism correction were 0.1 and 0.15, respectively, in the right eye and 0.6 and 0.7, respectively, in the left eye. Occlusion therapy with an eye patch over the left eye for one hour daily was started. At the age of four years and 10 months, the best-corrected visual acuity was 0.7 in both eyes. At the age of six years, occlusion therapy was discontinued, and full-correction glasses were prescribed, based on cycloplegic refraction. The visual acuity in the right eye decreased to 0.3 at the age of 11 years and further to 0.1 at the age of 12 years, while the visual acuity in the left eye remained 0.8. Afterwards, she maintained a visual acuity of 0.1 in the right eye and 0.8 in the left eye until the age of 22 years. An incidental presence of primary congenital glaucoma in this patient led to the detection of retinitis pigmentosa in earlier years and allowed long-term follow-up for 22 years. Even though genetic testing was not performed for this patient, the abnormal function of primary cilia, designated as ciliopathy, might explain the co-occurrence of primary congenital glaucoma and retinitis pigmentosa. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=ciliopathy kn-keyword=ciliopathy en-keyword=cycloplegic refraction kn-keyword=cycloplegic refraction en-keyword=full-correction glasses kn-keyword=full-correction glasses en-keyword=goldmann perimetry kn-keyword=goldmann perimetry en-keyword=occlusion therapy kn-keyword=occlusion therapy en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=photoreceptor ellipsoid zone kn-keyword=photoreceptor ellipsoid zone en-keyword=primary congenital glaucoma kn-keyword=primary congenital glaucoma en-keyword=retinitis pigmentosa kn-keyword=retinitis pigmentosa en-keyword=trabeculotomy kn-keyword=trabeculotomy END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=98 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic and phenotypic identities of Staphylococcus coagulans isolated from pustules of dogs with superficial bacterial folliculitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Staphylococcus coagulans, formerly called Staphylococcus schleiferi subsp. coagulans is the second most common isolate from skin lesions of dogs with superficial bacterial folliculitis (SBF). However, the clinical significance of S. coagulans in pustules of canine SBF remains uncertain. This study aimed to investigate the prevalence and genotypic and phenotypic diversity of S. coagulans isolated from pustules in two dogs with SBF.
Results Two dogs with SBF were included in this study. S. schleiferi/coagulans was isolated as the sole organism from three pustules in case #1, whereas it coexisted with S. pseudintermedius in two of seven pustules in case #2. S. pseudintermedius was the sole organism in the remaining five pustules in case #2. Whole genome sequences revealed that all isolates tested were annotated as S. coagulans. The isolates from the same pustules exhibited identical genotypic and phenotypic profiles, indicating clonal multiplication. S. coagulans isolated from different pustules exhibited similar yet distinct genotypic and phenotypic profiles.
Conclusions S. coagulans with identical genetic and phenotypic profiles can be identified as the sole pathogen or coexist with S. pseudintermedius in the pustules of the same dogs with SBF. en-copyright= kn-copyright= en-aut-name=OsumiTakafumi en-aut-sei=Osumi en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinomiyaYuuki en-aut-sei=Shinomiya en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WanganuttaraThamonwan en-aut-sei=Wanganuttara en-aut-mei=Thamonwan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImanishiIchiro en-aut-sei=Imanishi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimazakiYotaro en-aut-sei=Shimazaki en-aut-mei=Yotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IyoriKeita en-aut-sei=Iyori en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyodaYoichi en-aut-sei=Toyoda en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IdeKaori en-aut-sei=Ide en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishifujiKoji en-aut-sei=Nishifuji en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Animal Medical Center, Faculty of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=2 en-affil=Department of Veterinary Medicine, Faculty of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=3 en-affil=Department of Bacteriology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Kimberly and Eric J.

Its guanidine moiety, while essential for NET binding, presents major radiosynthetic challenges due to high basicity and the harsh deprotection conditions required for protected precursors. Previous methods relied on multistep procedures, strong acids, and complex purification, limiting clinical translation. This study aimed to develop a practical one-step radiosynthesis suitable for routine and automated production. Methods: A direct SN2-type nucleophilic [18F]fluorination was performed using an unprotected guanidine precursor to eliminate deprotection steps. Reaction parameters, including the base system, solvent composition, precursor concentration, and temperature, were optimized under conventional and microwave heating. Radiochemical conversion (RCC) and operational robustness were evaluated, and purification strategies were assessed for automation compatibility. Results: Direct [18F]fluorination using the unprotected precursor reduced the total synthesis time to 60?70 min. Optimal conditions employed a tert-butanol/acetonitrile (4:1) solvent system with K2CO3/Kryptofix222, affording RCC up to 33% under conventional heating. Microwave irradiation further improved efficiency, achieving RCC of up to 64% within 1.5 min at 140 °C. The method showed broad tolerance to variations in the base molar ratio and precursor concentration and enabled isocratic HPLC purification. Conclusions: This one-step radiosynthesis overcomes longstanding challenges in [18F]fluproxadine production by eliminating harsh deprotection and enabling high-yield, automation-ready synthesis, thereby improving clinical feasibility. en-copyright= kn-copyright= en-aut-name=ChenXinyu en-aut-sei=Chen en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhtaKaito en-aut-sei=Ohta en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraHiroyuki en-aut-sei=Kimura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YagiYusuke en-aut-sei=Yagi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiTakanori en-aut-sei=Sasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NoseNaoko en-aut-sei=Nose en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkehiMasaru en-aut-sei=Akehi en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaneTomohiko en-aut-sei=Yamane en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WernerRudolf A. en-aut-sei=Werner en-aut-mei=Rudolf A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Agency for Health, Safety and Environment, Kyoto University kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Molecular Imaging Research, Kobe City Medical Center General Hospital kn-affil= affil-num=9 en-affil=Department of Nuclear Medicine, LMU Hospital, and German Cancer Consortium (DKTK), Partner Site Munich, Ludwig-Maximilians-University of Munich kn-affil= affil-num=10 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=norepinephrine transporter kn-keyword=norepinephrine transporter en-keyword=positron emission tomography kn-keyword=positron emission tomography en-keyword=[18F]AF78 kn-keyword=[18F]AF78 en-keyword=[18F]fluproxadine kn-keyword=[18F]fluproxadine en-keyword=radiolabeling kn-keyword=radiolabeling END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=5 article-no= start-page=2113 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fgf10 Gene Dosage from a Single Allele Is Insufficient for Forming Multilayered Epithelial Cells in the Murine Lacrimal Gland en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mutations in the fibroblast growth factor 10 (FGF10) gene in humans cause aplasia of the lacrimal and salivary glands (ALSG). In patients with ALSG, heterozygous loss-of-function mutations are found, and FGF10 haploinsufficiency results in the absence of these secretory organs. Lacrimal glands (LGs) are formed through epithelial thickening, budding, and branching morphogenesis. To compare the variable phenotypes of the Fgf10+/? Harderian glands (HGs) previously reported, we examined the development of LGs in wild-type (WT), Fgf10+/?, and Fgf10-null mice. Pax6 immunostaining was performed to visualize the LG primordia from embryonic day 15.5 (E15.5) onwards. In situ hybridization of the genes encoding the epithelial receptor of FGF10, FGFR2b, and its other ligands was performed to determine their potential involvement in LG development. LG primordia were not observed in Fgf10+/? mice bilaterally at E16.5 or later stages. At E15.5, budding from the developing conjunctival epithelium (CE) was observed in a small fraction of the Fgf10+/? LG primordia. In contrast, the Fgf10-null CE failed to promote budding. Among Fgf1, Fgf3, Fgf7, Fgf10, and Fgf22, Fgf10 was expressed in the mesenchyme surrounding developing LG epithelial cells, whereas Fgf1 was expressed in the LG epithelium of WT mice. Fgf7 was initially expressed in the mesenchyme surrounding the nascent LG epithelium, but its expression subsequently became diffused. Thus, we conclude that among the FGFR2b ligands, initial LG formation is dependent on the mesenchymal factors FGF10 and FGF7, and FGF1 is likely to function as an epithelial factor in the LG primordia. A single allele of Fgf10 was found to be insufficient to support the budding process during LG morphogenesis. en-copyright= kn-copyright= en-aut-name=IkedaShiori en-aut-sei=Ikeda en-aut-mei=Shiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TajikaYuki en-aut-sei=Tajika en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaHirofumi en-aut-sei=Fujita en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyaishiSatoru en-aut-sei=Miyaishi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Gumma Prefectural College of Health Sciences kn-affil= affil-num=4 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Legal Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fibroblast growth factor kn-keyword=fibroblast growth factor en-keyword=Fgf10 kn-keyword=Fgf10 en-keyword=Fgf1 kn-keyword=Fgf1 en-keyword=Fgf3 kn-keyword=Fgf3 en-keyword=Fgf7 kn-keyword=Fgf7 en-keyword=Fgf22 kn-keyword=Fgf22 en-keyword=Fgfr2b kn-keyword=Fgfr2b en-keyword=mouse kn-keyword=mouse en-keyword=lacrimal gland kn-keyword=lacrimal gland en-keyword=development kn-keyword=development END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1716939 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural analysis of PSI-ACPI and PSII-ACPII supercomplexes from a cryptophyte alga Rhodomonas sp. NIES-2332 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Light energy is converted to chemical energy by two photosystems (PSI and PSII) in complex with their light-harvesting complex proteins (LHCI and LHCII) in photosynthesis. Rhodomonas is a member of cryptophyte alga whose LHCs contain unique chlorophyll a/c proteins (ACPs) and phycobiliproteins. We purified PSI-ACPI and PSII-ACPII supercomplexes from a cryptophyte Rhodomonas sp. NIES-2332 and analyzed their structures at high resolutions of 2.08 ? and 2.17 ?, respectively, using cryo-electron microscopy. These structures are largely similar to those reported previously from two other species of cryptophytes, but exhibited some differences in both the pigment locations and subunit structures. A part of the antenna subunits of both photosystems is shifted compared with the previously reported structures from other species of cryptophytes, suggesting some differences in the energy transfer rates from the antenna to the PSI and PSII cores. Newly identified lipids are found to occupy the interfaces between the antennae and cores, which may be important for assembly and stabilization of the supercomplexes. Water molecules surrounding three iron-sulfur clusters of the PSI core are found in our high-resolution structure, some of which are conserved from cyanobacteria to higher plants but some are different. In addition, our structure of PSII-ACPII lacks the subunits of oxygen-evolving complex as well as the Mn4CaO5 cluster, suggesting that the cells are in the S-growth phase, yet the PSI-ACPI structure showed the binding of PsaQ, suggesting that it is in an L-phase. These results suggest that the S-phase and L-phase can co-exist in the cryptophytic cells. The high-resolution structures of both PSI-ACPIs and PSII-ACPIIs solved in this study provide a more solid structural basis for elucidating the energy transfer and quenching mechanisms in this group of the organisms. en-copyright= kn-copyright= en-aut-name=ZhangWenyue en-aut-sei=Zhang en-aut-mei=Wenyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoneharaNozomi en-aut-sei=Yonehara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiiMizuki en-aut-sei=Ishii en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangHaowei en-aut-sei=Jiang en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=La RoccaRomain en-aut-sei=La Rocca en-aut-mei=Romain kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsaiPi-Cheng en-aut-sei=Tsai en-aut-mei=Pi-Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiHongjie en-aut-sei=Li en-aut-mei=Hongjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkitaFusamichi en-aut-sei=Akita en-aut-mei=Fusamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cryptophytes kn-keyword=cryptophytes en-keyword=Rhodomonas kn-keyword=Rhodomonas en-keyword=photosystem I kn-keyword=photosystem I en-keyword=photosystem II kn-keyword=photosystem II en-keyword=light-harvesting complex kn-keyword=light-harvesting complex en-keyword=photosynthesis kn-keyword=photosynthesis END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=13 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pan-cancer profiling links C1orf50 to DNA repair and immune modulation in ovarian cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background C1orf50 encodes a small, evolutionarily conserved protein, the function of which remains unclear. Its significance across various human cancers, particularly its specific role in ovarian cancer within an immunogenomic context, is not yet fully understood. Utilizing The Cancer Genome Atlas and single-cell RNA sequencing (scRNA-seq) public datasets, we conducted a comprehensive profiling of C1orf50 across multiple cancer types, with a particular focus on ovarian cancer, to investigate its associations with copy-number status, genomic instability, tumor programs, and the immune microenvironment.
Results Across cancer types, copy-number gain or amplification of C1orf50 was most frequent in ovarian cancer and closely tracked with higher messenger RNA levels. Higher C1orf50 expression was associated with a greater tumor mutational burden and homologous recombination deficiency, as indicated by gene-set patterns that suggested heightened cell-cycle and cellular stress responses accompanied by reduced oxidative phosphorylation, enrichment of regulatory T cells, and depletion of resting memory CD4 T cells. In ovarian cancer, focal events at chromosome 1p34.2 were accompanied by stepwise increases in C1orf50 expression by clinical stage and were linked to higher tumor mutational burden, homologous recombination deficiency, and greater loss of heterozygosity, together with more frequent gene alterations in BRCA1 or BRCA2. Immune composition clustered into profiles consistent with an immunosuppressive context in tumors with higher C1orf50 expression. The scRNA-seq data further revealed that cancer cells enhanced immune-suppressive interactions with various immune cell populations and diminished antigen-presentation signals. Analyses of genomic instability in ovarian cancer suggested mutational processes compatible with base-substitution patterns associated with cytidine deaminase activity and with insertion-deletion patterns characteristic of homologous recombination failure, while transcript-level patterns pointed to a broad downshift of canonical DNA repair activity with apparent compensatory adjustments in related pathways rather than a uniform change in any single pathway.
Conclusions The overexpression of C1orf50 characterizes an aggressive immunogenomic phenotype in ovarian cancer, distinguished by genomic instability, impaired DNA repair mechanisms, and extensive immunosuppression. These findings indicate that C1orf50 warrants consideration as a potential biomarker and a prospective target for therapeutic investigation. Furthermore, they advocate for the progression to prospective validation and functional studies to ascertain its clinical significance. en-copyright= kn-copyright= en-aut-name=RogachevskayaAnna en-aut-sei=Rogachevskaya en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtsuAkira en-aut-sei=Ohtsu en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChinVanessa D. en-aut-sei=Chin en-aut-mei=Vanessa D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Pe?aTirso en-aut-sei=Pe?a en-aut-mei=Tirso kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AraiSeiji en-aut-sei=Arai en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaAtsushi en-aut-sei=Tanaka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Harvard Medical School kn-affil= affil-num=4 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=5 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=6 en-affil=Department of Urology, Gunma University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Molecular Physiology, Faculty of Medicine, Graduate School of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=Pan-cancer analysis kn-keyword=Pan-cancer analysis en-keyword=DNA repair kn-keyword=DNA repair en-keyword=Gene expression kn-keyword=Gene expression en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment en-keyword=Immune evasion kn-keyword=Immune evasion en-keyword=Single-cell RNA-seq kn-keyword=Single-cell RNA-seq END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TeMPRA: advancing continuing professional development in pediatric rheumatology in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In the context of the global shortage of pediatric rheumatologists, mid-career specialists who can play key roles in regional education, research, and clinical practice have become increasingly important. In Japan, the Team of Mid-career Pediatric Rheumatologists Alliance (TeMPRA) was founded in 2014 to support continuing professional development (CPD) and foster collaboration among mid-career pediatric rheumatologists. The aim of this study was to characterize the current status and future perspectives of the TeMPRA members.
Methods In 2024, a cross-sectional, web-based survey was conducted among all 37 active members of the TeMPRA across Japan. Data were collected on career trajectories, educational roles, research activities, clinical practices, and international engagement. Categorical variables were compared using appropriate statistical tests, with a significance level of 0.05.
Results Responses were obtained from 35 members (response rate: 95%). Most respondents (71%) were affiliated with university hospitals, and 60% had?>?10 years of experience in pediatric rheumatology. Compared with those working in community hospitals, respondents affiliated with university hospitals were significantly more likely to be involved in research activities (50% vs. 0%, P?=?0.0261) and global professional contributions (88% vs. 0%, P? Conclusions This nationwide survey highlights the substantial educational roles, research activities, and clinical practices of mid-career pediatric rheumatologists in Japan and suggests that the TeMPRA framework can serve as a valuable model for supporting CPD and workforce sustainability. Similar alliance-based approaches may be applicable in other countries facing comparable challenges in pediatric rheumatology. en-copyright= kn-copyright= en-aut-name=WakiguchiHiroyuki

kn-title=Ultrafast Time-Compressive CMOS Image Sensors Based on Multitap Charge Modulators for Filming Light-In Flight en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ultrafast time-compressive CMOS image sensors based on multitap charge modulators can capture light-in flight using coded exposure masks on the focal plane. Transient images can then be reconstructed using iterative methods or deep learning models. Although the image sensor is based on indirect time-of-flight (ToF) image sensors, the reconstructed images are equivalent to those captured by direct ToF (D-ToF) image sensors. Important design parameters of the image sensor include the pixel block size and the number of taps of the charge modulator. Several constraints regarding the charge transfer of the multitap charge modulator, the hamming distance between exposure codes at adjacent timings, and the minimal time window duration must be considered when designing exposure codes. The influence of these factors on the fidelity of the reconstructed images is analyzed numerically. The results show that a pixel block size of 4×4 is optimal and that four or more taps are required for light detection and ranging (LiDAR) applications when 32 transient images of light-in flight are reconstructed. To demonstrate LiDAR in a scene with multipath interference, two objects were observed through a weakly diffusive sheet. The temporal resolution, as defined by the clock period of the exposure codes, was 1.65 ns. Multiple reflections were reconstructed using an iterative method (TVAL3) and a deep learning model (ADMM-Net). Although the waveforms of optical pulses reconstructed by TVAL3 are distorted, the amplitudes are more accurate. Conversely, although ADMM-Net reconstructs sharper optical pulses, the amplitudes are inaccurate. To achieve the shorter temporal resolution required for time-resolved diffuse optical tomography (DOT) and fluorescence lifetime imaging (FLIm), the feasibility of heterodyne compression was demonstrated through simulation. en-copyright= kn-copyright= en-aut-name=KagawaKeiichiro en-aut-sei=Kagawa en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiDaisuke en-aut-sei=Hayashi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakuraArashi en-aut-sei=Takakura en-aut-mei=Arashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmekiYuto en-aut-sei=Umeki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaMichitaka en-aut-sei=Yoshida en-aut-mei=Michitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YasutomiKeita en-aut-sei=Yasutomi en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawahitoShoji en-aut-sei=Kawahito en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChaeYoungcheol en-aut-sei=Chae en-aut-mei=Youngcheol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagaharaHajime en-aut-sei=Nagahara en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=2 en-affil=Graduate School of Integrated Science and Technology, Shizuoka University kn-affil= affil-num=3 en-affil=Faculty of Engineering, Shizuoka University kn-affil= affil-num=4 en-affil=Graduate School of Integrated Science and Technology, Shizuoka University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=7 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=8 en-affil=Department of Electrical and Electronic Engineering, Yonsei University kn-affil= affil-num=9 en-affil=D3 Center, The University of Osaka kn-affil= en-keyword=CMOS image sensor kn-keyword=CMOS image sensor en-keyword=compressive imaging kn-keyword=compressive imaging en-keyword=computational photography (CP) kn-keyword=computational photography (CP) en-keyword=multitap charge modulator kn-keyword=multitap charge modulator en-keyword=transient imaging kn-keyword=transient imaging END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue= article-no= start-page=107048 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=A cross-sectional study of the gut microbiota associated with urinary and serum equol production status in a general population of Japanese men en-subtitle= kn-subtitle= en-abstract= kn-abstract=Equol is a metabolite produced by the gut microbiota from the soy isoflavone daidzein. Previous studies identified bacteria capable of converting daidzein to equol. We investigated whether equol producers among Japanese with a high soy intake contained these bacteria. We also examined differences in equol production status between urine and serum and how the gut microbiota differs between these statuses. To minimize the potential confounding effects of hormonal variability in women, this cross-sectional study analyzed 853 Japanese men. Urinary and serum isoflavones were collected in the morning after fasting and were analyzed using LC-MS/MS. By applying a finite mixture model for each log10 equol/daidzein ratio, we defined equol producers and non-producers from urine and serum. Among 669 participants with fecal microbial measurements, the 16S rRNA gene was sequenced on a MiSeq System. The cut-off values for the log10 equol/daidzein ratio were ?0.94 for urine and ?0.95 for serum. Equol production status in urine and serum matched in 97 %, and equol producers from urine or serum were 42 %. The microbiota was more diverse in producers than in non-producers; the genus Senegalimassilia included strains with high sequence identity (>98 %) to daidzein reductase. The family Oscillospiraceae and class Clostridia also had approximately 46 %?48 % sequence identity. The equol production status of fasting urine and serum almost matched among a general population of Japanese men. Although we did not detect a microbiota with known daidzein reductase in equol producers, several shared similar sequences; these may include equol-producing bacteria that have not yet been identified. en-copyright= kn-copyright= en-aut-name=OkamiYukiko en-aut-sei=Okami en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ArimaHisatomi en-aut-sei=Arima en-aut-mei=Hisatomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BambaShigeki en-aut-sei=Bamba en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NamaiFu en-aut-sei=Namai en-aut-mei=Fu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoKeiko en-aut-sei=Kondo en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IdenoYuki en-aut-sei=Ideno en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SoejimaAyumi en-aut-sei=Soejima en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyakawaHaruna en-aut-sei=Miyakawa en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToriiSayuki en-aut-sei=Torii en-aut-mei=Sayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SegawaHiroyoshi en-aut-sei=Segawa en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OhashiMizuki en-aut-sei=Ohashi en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawashimaMegumi en-aut-sei=Kawashima en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KadotaAya en-aut-sei=Kadota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SekikawaAkira en-aut-sei=Sekikawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=FujiyoshiAkira en-aut-sei=Fujiyoshi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=SESSA Research Group en-aut-sei=SESSA Research Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=2 en-affil=Department of Preventive Medicine and Public Health, Faculty of Medicine, Fukuoka University kn-affil= affil-num=3 en-affil=Department of Fundamental Nursing, Shiga University of Medical Science kn-affil= affil-num=4 en-affil=Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=5 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=6 en-affil=Gunma University Center for Food Science and Wellness kn-affil= affil-num=7 en-affil=Nutraceuticals Research Institute, R&D Headquarters, Nutraceuticals Division, Otsuka Pharmaceutical Co., Ltd. kn-affil= affil-num=8 en-affil=Nutraceuticals Research Institute, R&D Headquarters, Nutraceuticals Division, Otsuka Pharmaceutical Co., Ltd. kn-affil= affil-num=9 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=10 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=11 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=12 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=13 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=15 en-affil=Department of Epidemiology, School of Public Health, University of Pittsburgh kn-affil= affil-num=16 en-affil=Department of Hygiene, Wakayama Medical University kn-affil= affil-num=17 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=18 en-affil= kn-affil= en-keyword=Equol kn-keyword=Equol en-keyword=Soy kn-keyword=Soy en-keyword=Isoflavone kn-keyword=Isoflavone en-keyword=Gut microbiota kn-keyword=Gut microbiota en-keyword=Men kn-keyword=Men en-keyword=Producers kn-keyword=Producers END start-ver=1.4 cd-journal=joma no-vol=779 cd-vols= no-issue= article-no= start-page=110775 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=Comparison of bioavailability of quercetin and its structural analogs in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Flavonoids are thought to provide beneficial effects on health. However, there are still uncertainties regarding their bioavailability. In this study, we investigated the bioavailability of 6 flavonoids, galangin, kaempferol, quercetin, myricetin, fisetin, and luteolin, by oral administration to mice. Analysis of plasma concentrations of free flavonoids after deconjugation by LC-MS/MS revealed that all flavonoids were rapidly absorbed after administration. Among 6 flavonoids, kaempferol and fisetin showed high absorbed amounts in blood plasma. With the LogP value of the two flavonoids as the maximum value, the amount absorbed decreased for both lower and higher LogP values. The results of the tissue distribution of galangin, kaempferol, and quercetin suggested that the order of fastest movement from the stomach to the small intestine was kaempferol?>?quercetin?>?galangin. In addition, the amount of kaempferol and quercetin distributed in the liver was greater than that of galangin. These results suggest that the bioavailability of flavonoids varies with the slight structural differences, possibly due to differences in their rapid accessibility to the small intestine that is the primary site of absorption and metabolism within the body. en-copyright= kn-copyright= en-aut-name=MaedaNozomi en-aut-sei=Maeda en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HashimotoAtsushi en-aut-sei=Hashimoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaRyosei en-aut-sei=Morita en-aut-mei=Ryosei 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=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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 Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=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=Flavonoid kn-keyword=Flavonoid en-keyword=Bioavailability kn-keyword=Bioavailability en-keyword=Distribution kn-keyword=Distribution END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=1877 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Surgical Procedures for Rheumatoid Forefoot Deformities on Radiographic Foot Length and Width Variations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The number of patients with rheumatoid arthritis (RA) undergoing forefoot arthroplasty has increased to better control the disease. Despite patients frequently expressing concerns regarding postoperative foot appearance and footwear-related expectations, no study has investigated postoperative changes in foot length and width in patients with RA. The aim of this study was to evaluate the effect of surgical procedures for rheumatoid forefoot deformities on variations in radiologically determined foot length and width. Methods: In total, 72 feet of 50 women and 3 men (average age: 66.7 years) underwent joint-preserving arthroplasty (n = 33) and arthrodesis of the first metatarsophalangeal joint with shortening osteotomy of the lesser metatarsals or resection arthroplasty of the lesser metatarsal heads (n = 39); procedures were carried out in our institute from August 2013 to February 2020. The mean disease duration was 23.5 years, and the average follow-up period was 17.5 months. Pre- and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA) of the first and second metatarsals (M1M2A), and IMA of the first and fifth metatarsals (M1M5A) were measured on weightbearing radiographs as well as foot length and width. We also evaluated the correlation between changes in radiographic parameters and variations in radiologically determined foot length and width. Results: Radiologically determined foot width changed significantly from 10.1 cm to 9.7 cm (p < 0.01), while no significant difference was found between pre- and postoperative radiologically determined foot length. HVA, M1M2A, and M1M5A were significantly improved after the surgery (p < 0.01, p < 0.01, and p < 0.01, respectively). A significant negative correlation was found between the variation in radiologically determined foot length and changes in HVA (r = ?0.29, p = 0.02) and M1M5A (r = ?0.23, p < 0.05), while a significant positive correlation was found between the variation in the foot width and changes in HVA (r = 0.34, p < 0.01), M1M2A (r = 0.55, p < 0.01), and M1M5A (r = 0.45, p < 0.01). There were no significant differences between operative procedures regarding variation in radiologically determined foot length and width. Conclusions: Surgical procedure for rheumatoid forefoot deformity improved radiographic parameters and reduced radiographic foot width while maintaining foot length. en-copyright= kn-copyright= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KisoYohei en-aut-sei=Kiso en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaigaKenta en-aut-sei=Saiga en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Kurashiki Sweet Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=4 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= en-keyword=forefoot surgery kn-keyword=forefoot surgery en-keyword=foot length kn-keyword=foot length en-keyword=foot width kn-keyword=foot width en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=2 article-no= start-page=023F01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feedback-Controlled Beam Pattern Measurement Method Using a Power-Variable Calibration Source for Cosmic Microwave Background Telescopes en-subtitle= kn-subtitle= en-abstract= kn-abstract=We demonstrate a novel beam pattern measurement method for the side lobe characterization of cosmic microwave background telescopes. The method employs a power-variable artificial microwave source under feedback control from the detector under test on the telescope. It enables us to extend the dynamic range of the beam pattern measurement without introducing nonlinearity effects from the detector. We conducted a laboratory-based proof-of-concept experiment, measuring the H-plane beam pattern of a horn antenna coupled to a diode detector at 81 GHz. We gained an additional dynamic range of 60.3 dB attributed to the feedback control. In addition, we verified the measurement by comparing it with other reference measurements obtained using conventional methods. The method is also applicable to general optical measurements requiring a high dynamic range to detect subtle nonidealities in the characteristics of optical devices. en-copyright= kn-copyright= en-aut-name=HiroseHaruaki en-aut-sei=Hirose en-aut-mei=Haruaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaMasaya en-aut-sei=Hasegawa en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanekoDaisuke en-aut-sei=Kaneko en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagasakiTaketo en-aut-sei=Nagasaki en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakuRyota en-aut-sei=Takaku en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=de?HaanTijmen en-aut-sei=de?Haan en-aut-mei=Tijmen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakakuraSatoru en-aut-sei=Takakura en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujinoTakuro en-aut-sei=Fujino en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Physics, Graduate School of Engineering Science, Yokohama National University kn-affil= affil-num=2 en-affil=Institute of Particle and Nuclear Studies (IPNS), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=3 en-affil=International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (WPI-QUP), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=4 en-affil=Accelerator Laboratory (ACCL), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Institute of Particle and Nuclear Studies (IPNS), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=7 en-affil=Department of Physics, Faculty of Science, The University of Tokyo kn-affil= affil-num=8 en-affil=International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (WPI-QUP), High Energy Accelerator Research Organization (KEK) kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=e7467 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Technique for Repositioning the Posteriorly Displaced Premaxilla Following Prior Repair of Complete Bilateral Cleft Lip en-subtitle= kn-subtitle= en-abstract= kn-abstract=It is well known that osteotomy of the premaxilla is an effective surgical procedure for the correction of a displaced premaxilla in patients with bilateral cleft lip and palate. In cases with a posteriorly displaced premaxilla, it is not easy to move the premaxilla forward because of scarring of the palatal mucosal attachment, narrowing of the adjacent maxillary segments, and the stable fixation of this bone segment after its movement. This fixation is also important in cases without secondary bone grafting. We propose a new method that combines osteotomy and a method such as bone distraction for cases with significant premaxilla displacement that are difficult to repair by osteotomy alone. A conventional orthodontic palatal expander was used as the distractor. The anterior arms were bent at the posterior part of the lingual side of the anterior teeth, and a resin base was attached to the arm parts. The posterior arms were bent and waxed onto the bands of both first molars. Supportive stainless steel wire arms, which are attached to the rest of the deciduous molars, stabilize the distractor. After the osteotomy of the premaxilla, distraction was performed at a rate of 1.0 mm per day, starting the day after surgery. Because the premaxilla of patients with bilateral cleft lip and palate has undergone multiple surgical interventions, the soft tissue is not mobile, making it impossible to guide the premaxilla to an ideal position in a single stage. However, this procedure, using this semirigid distractor, makes it possible to move the osteotomized premaxilla to the planned position with firm stability. en-copyright= kn-copyright= en-aut-name=ArimuraYuki en-aut-sei=Arimura en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaSeiji en-aut-sei=Iida en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HyodoAiko en-aut-sei=Hyodo en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikamiAyaka en-aut-sei=Mikami en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakemotoFumiko en-aut-sei=Takemoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=96 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of an oral exercise intervention on pre-frailty or frailty in older people: a randomized clinical trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Frailty is often experienced by older adults, which can lead to long-term health problems. We aimed to examine associations with improvements in nutritional status, sarcopenia (age-related loss of skeletal muscle mass and strength), and frailty in four groups with different oral exercise frequencies.
Methods: We conducted a prospective, parallel multi-arm randomized controlled trial (Japan Registry of Clinical Trials (jRCT) 1062210063) to test the effects of oral exercise on frailty in older adults. Each intervention consisted of a standardized oral exercise protocol including neck exercises, lip exercises, and tongue movements, designed to improve oral function and reduce frailty. The primary outcome was the change in the number of frailty criteria from baseline to follow-up. Individuals aged ?60 years were screened for frailty status using standardized criteria at the Department of Preventive Dentistry at Okayama University Hospital between October 2022 and December 2023. Those identified as pre-frailty or frailty were eligible and enrolled in the study. After screening 60 individuals, 58 eligible participants were randomly assigned using block randomization to one of four oral exercise frequency groups: 3 times/day & everyday, 3 times/day & 3 days/week, once/day & everyday, and once/day & 3 days/week. A two-way repeated measures analysis of variance was used to evaluate the impact of the four frequencies of oral exercise methods on frailty in older adults. Outcome assessors were blinded; participants were not.
Results: Here we show the results of the 58 participants. Group sizes are: 3 times/day & everyday (n?=?14), 3 times/day & 3 days/week (n?=?15), once/day & everyday (n?=?14), once/day & 3 days/week (n?=?15). The trial is completed as planned, and all randomized participants are analyzed. The main effect of time is significant for the number of frailty criteria (F?=?14.803, p? Conclusions: After conducting oral exercises for 3 months on older adults with pre-frailty or frailty, improvements in frailty are observed. Overall, these exercises could be a simple, low-cost way to support healthy aging in the community. en-copyright= kn-copyright= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InadaSakura en-aut-sei=Inada en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Section of Preventive and Public Health Dentistry, Division of Oral Health, Growth and Development, Faculty of Dental Science, Kyushu University kn-affil= affil-num=3 en-affil=Division of Health Promotion, Okayama-City Health Center kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, Faculty of Health Care Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=e5 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of sagging correction calibration error on radiation therapy equipment using image analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: This study investigates the effect of sagging correction errors on image quality and geometric coordinate accuracy.
Methods: This study utilised the Elekta radiotherapy system, ball bearing (BB), Catphan phantom and MultiMet-WL phantom. Ten distinct flex maps (FMs) were acquired by positioning the BB at the accuracy isocentre and introducing shifts of 0.2, 0.4 and 0.6 mm in the left, table and up directions, respectively. Cone-beam computed tomography images of the Catphan phantom were acquired using 10 FMs. The images were analysed for modulation transfer function (MTF) values and geometric coordinates. Additionally, the Winston?Lutz (W-L) test was conducted under reference couch positions and with a 0.3 mm couch shift.
Results: For the Catphan phantom analysis, the standard deviations of MTF10% across FMs were 0.19. The centre-of-gravity coordinates of the insert exhibited shifts of approximately 0.2, 0.4 and 0.6 mm when comparing reference images to those acquired with the shifted FMs. The results of the W-L test with a 0.3 mm couch shift showed radiation isocentre deviations exceeding 1 mm compared to the reference couch positions.
Conclusions: Minor sagging correction calibration errors did not remarkably impact image quality; however, they altered the geometric coordinates of the image isocentre. These calibration errors decreased the accuracy of off-isocentre positioning. en-copyright= kn-copyright= en-aut-name=FujiiYasushi en-aut-sei=Fujii en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakayamaTakahiro en-aut-sei=Nakayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshitaJunki en-aut-sei=Oshita en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsunodaAyaka en-aut-sei=Tsunoda en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaekiYusuke en-aut-sei=Saeki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Radiology, Chugoku Central Hospital of the Mutual Aid Association of Public School Teachers kn-affil= affil-num=2 en-affil=Department of Radiology, Chugoku Central Hospital of the Mutual Aid Association of Public School Teachers kn-affil= affil-num=3 en-affil=Department of Radiology, Chugoku Central Hospital of the Mutual Aid Association of Public School Teachers kn-affil= affil-num=4 en-affil=Department of Radiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=6 en-affil= Faculty of Medicine, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=flex map kn-keyword=flex map en-keyword=sagging kn-keyword=sagging en-keyword=Winston?Lutz test kn-keyword=Winston?Lutz test END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=2 article-no= start-page=2301 end-page=2310 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Total thymectomy is oncologically superior to partial thymectomy in patients with thymic carcinoma: insights from a multicenter real-world data analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although total thymectomy has been the standard surgical approach for thymic epithelial tumors, an increasing number of recent reports suggest that partial thymectomy for early-stage thymomas may yield outcomes comparable to those of total thymectomy. However, whether partial thymectomy is a viable alternative for thymic carcinoma remains unclear.
Materials and methods: A total of 106 patients with thymic carcinoma underwent curative intended resection at 19 institutions between January 2010 and December 2021. Excluding 14 patients with incomplete resection, 92 patients with thymic carcinoma who underwent total (n = 73) or partial thymectomy (n = 19) were compared. Overall survival (OS) and recurrence-free survival (RFS) were analyzed using Kaplan?Meier curves and Cox proportional hazard models. Overlap weighting was applied to adjust for potential confounding factors.
Results: Among patients with clinical stage I disease, 79.3% were upstaged to stage II or higher postoperatively. Unadjusted analyses revealed no statistically significant differences in OS and RFS between the total and partial thymectomy groups, although a trend toward poorer outcomes in the partial thymectomy group was observed. After overlap weighting, partial thymectomy was associated with significantly poorer OS (P = 0.0027) and higher recurrence risk (P < 0.0001). Early postoperative recurrence occurred more frequently in the partial thymectomy group.
Conclusion: Partial thymectomy was associated with significantly worse survival and recurrence outcomes in thymic carcinoma. Given the limitations of preoperative diagnosis, total thymectomy should remain the preferred surgical approach for undiagnosed thymic epithelial tumors to achieve optimal oncologic control and minimize the risk of recurrence. en-copyright= kn-copyright= en-aut-name=HayashiTatsuya en-aut-sei=Hayashi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

the interaction between collagen-binding protein (Cnm) of Streptococcus mutans and immunoglobulin (IgA) to clarify the possible involvement in IgA nephropathy (IgAN) development.
Methods: The binding of Cnm to human immunoglobulins was examined using an enzyme-linked immunosorbent assay. A nephritis-induced rat model was employed to confirm the localization of Cnm.
Results: IgA1 showed significantly greater binding ability to Cnm than to other bacterial surface proteins, and Cnm showed significantly greater binding ability to IgA1 than to other immunoglobulins. In rats administered Cnm, IgA deposition was observed in the glomerular mesangial region. Furthermore, biotin-labeled Cnm was observed in the same region as IgA deposition in the Cnm group.
Conclusions: Taken together, it is considered that following invasion into the bloodstream, Cnm binds to and forms a complex with IgA1, leading to deposition of IgA1 in renal glomeruli. en-copyright= kn-copyright= en-aut-name=MatsuokaDaiki en-aut-sei=Matsuoka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SueharaKana en-aut-sei=Suehara en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaShuhei en-aut-sei=Naka en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MisakiTaro en-aut-sei=Misaki en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagasawaYasuyuki en-aut-sei=Nagasawa en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItoSeigo en-aut-sei=Ito en-aut-mei=Seigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuehiroYuto en-aut-sei=Suehiro en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NomuraRyota en-aut-sei=Nomura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoKazuhiko en-aut-sei=Nakano en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Matsumoto-NakanoMichiyo en-aut-sei=Matsumoto-Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Nephrology, Seirei Hamamatsu General Hospital kn-affil= affil-num=5 en-affil=Department of General Internal Medicine, Hyogo Medical University kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Japan Self-Defense Force Iruma Hospital kn-affil= affil-num=7 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=8 en-affil=Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=9 en-affil=Department of Pediatric Dentistry, Graduate School of Dentistry, The University of Osaka kn-affil= affil-num=10 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bacterial surface proteins kn-keyword=bacterial surface proteins en-keyword=collagen-binding protein kn-keyword=collagen-binding protein en-keyword=human immunoglobulins kn-keyword=human immunoglobulins en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=Streptococcus mutans kn-keyword=Streptococcus mutans END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=4 article-no= start-page=1081 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Generative AI?Based Technical Data Extraction Tool for IoT Application Systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, Internet of Things (IoT) application systems play an essential role in smart cities, industry, healthcare, agriculture, and smart homes. For non-expert users, designing and implementing IoT application systems remains challenging, especially when configuring sensors, edge devices, and server platforms. To support configuration tasks of IoT application systems, we have developed an AI-based setup assistance tool. However, AI models still fail to reliably support newly released or previously unseen devices, sometimes producing incomplete or erroneous outputs that may lead to configuration failures. Incorporating their technical-document information into Retrieval-Augmented Generation (RAG) is an effective way to supplement AI knowledge and improve reliability. In this paper, we propose a generative AI-based technical data extraction tool to address the challenges. It extracts essential technical information using the schema-based extraction from given PDF or HTML datasheets and converts it into a structured format suitable for AI-supported configurations. A local vector database is used to enable semantic similarity retrieval and provide document-grounded evidence for RAG-based answering, ensuring consistent support for previously unseen IoT devices. For evaluations, we applied the proposal to several sensor and device datasheets and compared extracted specifications with ground-truth values to measure accuracy and completeness. Then, we compared end-to-end configuration QA reliability against a commercial baseline (ChatPDF) using the golden benchmark. The results show that the proposed tool reliably acquires key specifications and significantly improves end-to-end configuration QA reliability. Across 960 golden QA pairs, the proposed method improves Recall from 0.636 to 0.926 and Accuracy from 0.595 to 0.807 compared with ChatPDF. en-copyright= kn-copyright= en-aut-name=KongDezheng en-aut-sei=Kong en-aut-mei=Dezheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=internet of things kn-keyword=internet of things en-keyword=AI kn-keyword=AI en-keyword=retrieval-augmented generation kn-keyword=retrieval-augmented generation en-keyword=vector database kn-keyword=vector database en-keyword=schema-based extraction kn-keyword=schema-based extraction en-keyword=data sheet kn-keyword=data sheet en-keyword=technical information kn-keyword=technical information END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=2 article-no= start-page=110 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Slide Annotation System with Multimodal Analysis for Video Presentation Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the rapid growth of online presentations, there has been an increasing need for efficient review of recorded materials. In typical presentations, speakers verbally elaborate on each slide, providing details not captured in the slides themselves. Automatically extracting and embedding these verbal explanations at their corresponding slide locations can greatly enhance the review process for audiences. This paper presents a Slide Annotation System that employs a robust hybrid two-stage detector to identify slide boundaries, extracts slide text through Optical Character Recognition (OCR), transcribes narration, and employs a multimodal Large Language Model (LLM) to generate concise, context-aware annotations that are added to their corresponding slide locations. For evaluations, the technical performance was validated on five recorded presentations, while the user experience was assessed by 37 participants. The results showed that the system achieved a macro-average ?1 score of 0.879 (??=0.024, 95% ??[0.849,0.909]) for slide segmentation and 90.0% accuracy (95% ??[74.4%,96.5%]) for annotation alignment. Subjective evaluations revealed high annotation validity and usefulness as rated by presenters, and a high System Usability Scale (SUS) score of 80.5 (??=6.7, 95% ??[78.3,82.7]). Qualitative feedback further confirmed that the system effectively streamlined the review process, enabling users to locate key information more efficiently than standard video playback. These findings demonstrate the strong potential of the proposed system as an effective automated annotation system. en-copyright= kn-copyright= en-aut-name=HazAmma Liesvarastranta en-aut-sei=Haz en-aut-mei=Amma Liesvarastranta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FajriantiEvianita Dewi en-aut-sei=Fajrianti en-aut-mei=Evianita Dewi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SukaridhotoSritrusta en-aut-sei=Sukaridhoto en-aut-mei=Sritrusta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Human Centric Multimedia Research Laboratory, Department of Informatic and Computer Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=6 en-affil=Human Centric Multimedia Research Laboratory, Department of Informatic and Computer Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= en-keyword=slide annotation kn-keyword=slide annotation en-keyword=multimodal analysis kn-keyword=multimodal analysis en-keyword=speech-to-text kn-keyword=speech-to-text en-keyword=LLM kn-keyword=LLM en-keyword=SUS kn-keyword=SUS END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=65 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An SQL Query Description Problem with AI Assistance for an SQL Programming Learning Assistant System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Today, relational databases are widely used in information systems. SQL (structured query language) is taught extensively in universities and professional schools across the globe as a programming language for its data management and accesses. Previously, we have studied a web-based programming learning assistant system (PLAS) to help novice students learn popular programming languages by themselves through solving various types of exercises. For SQL programming, we have implemented the grammar-concept understanding problem (GUP) and the comment insertion problem (CIP) for its initial studies. In this paper, we propose an SQL Query Description Problem (SDP) as a new exercise type for describing the SQL query to a specified request in a MySQL database system. To reduce teachers’ preparation workloads, we integrate a generative AI-assisted SQL query generator to automatically generate a new SDP instance with a given dataset. An SDP instance consists of a table, a set of questions and corresponding queries. Answer correctness is determined by enhanced string matching against an answer module that includes multiple semantically equivalent canonical queries. For evaluation, we generated 11 SDP instances on basic topics using the generator, where we found that Gemini 3.0 Pro exhibited higher pedagogical consistency compared to ChatGPT-5.0, achieving perfect scores in Sensibleness, Topicality, and Readiness metrics. Then, we assigned the generated instances to 32 undergraduate students at the Indonesian Institute of Business and Technology (INSTIKI). The results showed an average correct answer rate of 95.2% and a mean SUS score of 78, which demonstrates strong initial student performance and system acceptance. en-copyright= kn-copyright= en-aut-name=WardaniNi Wayan en-aut-sei=Wardani en-aut-mei=Ni Wayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiartawanPutu en-aut-sei=Sugiartawan en-aut-mei=Putu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PutraI Nyoman Agus Suarya en-aut-sei=Putra en-aut-mei=I Nyoman Agus Suarya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Business and Creative Design, Indonesian Institute of Business and Technology kn-affil= en-keyword=database programming kn-keyword=database programming en-keyword=SQL query description problem (SDP) kn-keyword=SQL query description problem (SDP) en-keyword=self-study kn-keyword=self-study en-keyword=programming learning assistant system (PLAS) kn-keyword=programming learning assistant system (PLAS) en-keyword=generative AI kn-keyword=generative AI END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=2 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Threshold Selection Method in Code Plagiarism Checking Function for Code Writing Problem in Java Programming Learning Assistant System Considering AI-Generated Codes en-subtitle= kn-subtitle= en-abstract= kn-abstract=To support novice learners, the Java programming learning assistant system (JPLAS) has been developed with various features. Among them, code writing problem (CWP) assigns writing an answer code that passes a given test code. The correctness of an answer code is validated by running it on JUnit. In previous works, we implemented a code plagiarism checking function that calculates the similarity score for each pair of answer codes based on the Levenshtein distance. When the score is higher than a given threshold, this pair is regarded as plagiarism. However, a method for finding the proper threshold has not been studied. In addition, AI-generated codes have become threats in plagiarism, as AI has grown in popularity, which should be investigated. In this paper, we propose a threshold selection method based on Tukey’s IQR fences. It uses a custom upper threshold derived from the statistical distribution of similarity scores for each assignment. To better accommodate skewed similarity distributions, the method introduces a simple percentile-based adjustment for determining the upper threshold. We also design prompts to generate answer codes using generative AI and apply them to four AI models. For evaluation, we used a total of 745 source codes of two datasets. The first dataset consists of 420 answer codes across 12 CWP instances from 35 first-year undergraduate students in the State Polytechnic of Malang, Indonesia (POLINEMA). The second dataset includes 325 answer codes across five CWP assignments from 65 third-year undergraduate students at Okayama University, Japan. The applications of our proposals found the following: (1) any pair of student codes whose score is higher than the selected threshold has some evidence of plagiarism, (2) some student codes have a higher similarity than the threshold with AI-generated codes, indicating the use of generative AI, and (3) multiple AI models can generate code that resembles student-written code, despite adopting different implementations. The validity of our proposal is confirmed. en-copyright= kn-copyright= en-aut-name=PermatasariPerwira Annissa Dyah en-aut-sei=Permatasari en-aut-mei=Perwira Annissa Dyah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KinariSafira Adine en-aut-sei=Kinari en-aut-mei=Safira Adine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WaiKhaing Hsu en-aut-sei=Wai en-aut-mei=Khaing Hsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Engineering Science, Akita University kn-affil= en-keyword=Java programming learning kn-keyword=Java programming learning en-keyword=JPLAS kn-keyword=JPLAS en-keyword=JUnit kn-keyword=JUnit en-keyword=code writing problem kn-keyword=code writing problem en-keyword=plagiarism kn-keyword=plagiarism en-keyword=Levenshtein distance kn-keyword=Levenshtein distance en-keyword=threshold kn-keyword=threshold en-keyword=IQR kn-keyword=IQR en-keyword=AI-generated kn-keyword=AI-generated END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=24 article-no= start-page=4967 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An AI-Driven System for Learning MQTT Communication Protocols with Python Programming en-subtitle= kn-subtitle= en-abstract= kn-abstract=With rapid developments of wireless communication and Internet of Things (IoT) technologies, an increasing number of devices and sensors are interconnected, generating massive amounts of data in real time. Among the underlying protocols, Message Queuing Telemetry Transport (MQTT) has become a widely adopted lightweight publish?subscribe standard due to its simplicity, minimal overhead, and scalability. Then, understanding such protocols is essential for students and engineers engaging in IoT application system designs. However, teaching and learning MQTT remains challenging for them. Its asynchronous architecture, hierarchical topic structure, and constituting concepts such as retained messages, Quality of Service (QoS) levels, and wildcard subscriptions are often difficult for beginners. Moreover, traditional learning resources emphasize theory and provide limited hands-on guidance, leading to a steep learning curve. To address these challenges, we propose an AI-assisted, exercise-based learning platform for MQTT. This platform provides interactive exercises with intelligent feedback to bridge the gap between theory and practice. To lower the barrier for learners, all code examples for executing MQTT communication are implemented in Python for readability, and Docker is used to ensure portable deployments of the MQTT broker and AI assistant. For evaluations, we conducted a usability study using two groups. The first group, who has no prior experience, focused on fundamental concepts with AI-guided exercises. The second group, who has relevant background, engaged in advanced projects to apply and reinforce their knowledge. The results show that the proposed platform supports learners at different levels, reduces frustrations, and improves both engagement and efficiency. en-copyright= kn-copyright= en-aut-name=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Sandi KyawHtoo Htoo en-aut-sei=Sandi Kyaw en-aut-mei=Htoo Htoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PradhanaAnak Agung Surya en-aut-sei=Pradhana en-aut-mei=Anak Agung Surya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=7 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=IoT kn-keyword=IoT en-keyword=MQTT protocol kn-keyword=MQTT protocol en-keyword=AI-assisted learning kn-keyword=AI-assisted learning en-keyword=exercise-based education kn-keyword=exercise-based education en-keyword=Python programming kn-keyword=Python programming en-keyword=docker kn-keyword=docker en-keyword=learning platform kn-keyword=learning platform END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=63 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metastatic Intraocular Tumor Likely from Hepatocellular Carcinoma Mimicking Panuveitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 77-year-old man undergoing treatment for hepatocellular carcinoma (HCC) presented with blurred vision in his right eye, persisting for 2 months.

Although scroll painting is its most common form, thangkas are also created through embroidery, appliqu?, and brocade weaving. The subjects depicted encompass a wide range of themes within Tibetan Buddhism and the B?n religion, including various Buddhas, bodhisattvas, deities, monks, mandalas, as well as astronomical and medical knowledge. Within Tibetan religious beliefs, thangkas are not merely visual representations; they are venerated as supports of Buddha (Tib. sku rten), understood as physical embodiments of divine presence. At the same time, the creation and veneration of thangka constitute a rich aesthetic tradition in which artists repeatedly integrate realist elements into this sacred canvas.
This paper offers a micro anthropological examination (Tanaka 2005; 田中 2006) of the depiction of thangka as a practice oscillating between inscribing the canonical and drawing the real. Through critically engaging with the theory of agency of art (Gell 1998), and the analysis of writing and drawing (Ingold 2017), this study examines the dialectical relationship between rendering sacred images and depicting worldly reality, and how such practices unfold in the tension between prescriptive authority and embodied perception. en-copyright= kn-copyright= en-aut-name=ZHANGShijun en-aut-sei=ZHANG en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Sociology & Institute of Sociology and Anthropology, Peking University kn-affil= en-keyword=Tibetan thangka kn-keyword=Tibetan thangka en-keyword=art agent kn-keyword=art agent en-keyword=writing and drawing kn-keyword=writing and drawing END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=115 end-page=133 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=“God” is Coming to My Home : Catholic Images and the Sacred in the Case of a Rural Village in Western Mexico en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper aims to clarify the dynamic aspect of the sacred that the religious image is imbued with, focusing on a Catholic practice in a current rural village of western Mexico. In classical studies of the sacred, it has generally been considered disconnected from the profane and ambivalent. Other research has revealed the multi-layered nature of the sacred and its constructive aspect. In contrast, this paper will discuss a sacredness that arises from the interaction between human beings and objects, a sacredness that is both performative and intimate. Thus, this article will analyze practitioners’ everyday, contingent acts, free from formality. In conclusion, “the sacred” contains a part of the profane caused by the Catholic image going back and forth between the realms of “the sacred” and “the profane”. en-copyright= kn-copyright= en-aut-name=KAWAMOTONaomi en-aut-sei=KAWAMOTO en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Research Institute for the Dynamics of Civilizations, OKAYAMA UNIVERSITY kn-affil= en-keyword=the sacred kn-keyword=the sacred en-keyword=the catholic image kn-keyword=the catholic image en-keyword=intimacy kn-keyword=intimacy en-keyword=Child Jesus kn-keyword=Child Jesus en-keyword=Mexico kn-keyword=Mexico en-keyword=daily practice kn-keyword=daily practice END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=101 end-page=114 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From Festivals to the Everyday: The Circulation of Kumade at the Tori no Ichi at Hanazono Shrine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Every year in November, the Tori no Ichi festival draws huge crowds to the grounds of Hanazono Shrine in Shinjuku, Tokyo. The festival is centered around the buying and selling of kumade, or good luck rakes. These bold and colorful objects function as engimono, or good luck charms, purchased for business prosperity or home safety. This study explores the circulation and itinerary of kumade at the Tori no Ichi festival by analyzing the performances surrounding them. While previous scholarship on engimono has focused on their roles in domestic settings or disposal rituals, this research approaches them in situ at the festival. The study shows that these objects bridge the festival and the everyday, connecting people to the event and the sacred site through a dynamic network of social, spatial, and ritual practices. The research draws on fieldwork and in-depth interviews conducted at Hanazono Shrine between 2020 and 2024. en-copyright= kn-copyright= en-aut-name=TILLONENMia en-aut-sei=TILLONEN en-aut-mei=Mia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of English Language and Culture, FUJI WOMEN’S UNIVERSITY kn-affil= en-keyword=urban festival kn-keyword=urban festival en-keyword=material religion kn-keyword=material religion en-keyword=sacred object kn-keyword=sacred object en-keyword=performance kn-keyword=performance en-keyword=Tokyo kn-keyword=Tokyo END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Starch Synthase 3 isoforms are essential for normal starch granule initiation in wheat endosperm en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DingJinjin en-aut-sei=Ding en-aut-mei=Jinjin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FahyBrendan en-aut-sei=Fahy en-aut-mei=Brendan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsushimaRyo en-aut-sei=Matsushima en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangQiantao en-aut-sei=Jiang en-aut-mei=Qiantao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SeungDavid en-aut-sei=Seung en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=2 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Triticeae Research Institute, Sichuan Agricultural University kn-affil= affil-num=5 en-affil=John Innes Centre, Norwich Research Park kn-affil= en-keyword=resistant starch kn-keyword=resistant starch en-keyword=starch kn-keyword=starch en-keyword=starch granule kn-keyword=starch granule en-keyword=starch synthase kn-keyword=starch synthase en-keyword=wheat kn-keyword=wheat END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=100731 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Insights into the taste of organic acids via TAS1Rs en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Organic acids contribute significantly to the flavor of fermented foods by imparting sourness. Although mice generally avoid sour taste, previous studies have reported greater consumption of l-lactic acid than its d-enantiomer, suggesting enantiomer-specific recognition. This behavior is hypothesized to involve TAS1Rs, which consists of sweet/umami receptors. However, it remains unclear whether TAS1Rs additionally contribute to the recognition of other chiral organic acids. This study aimed to evaluate the role of TAS1Rs, particularly TAS1R3, in the modulation of enantiomer-dependent behavioral responses to organic acids in mice.
Methods: Behavioral responses were evaluated using 48-h and 1-h 2-bottle tests. Binding of organic acids to TAS1Rs was investigated by differential scanning fluorimetry (DSF) with the ligand-binding domain (LBD) of medaka Tas1r2a/Tas1r3.
Results: Wild-type mice consumed more d-malic acid than l-malic acid in the 48-h test, whereas Tas1r3-KO mice showed no such difference. This pattern was not observed in the short-term 1-h test, which minimized the contribution of post-ingestion and learned effects. DSF analysis revealed no binding of any of the tested organic acids to the LBD of medaka Tas1r2a/Tas1r3.
Conclusions: Organic acids may elicit TAS1R3-dependent post-ingestion signals that contribute to enantiomer-selective consumption in mice. Electrostatic interactions and hydrogen-bonding networks within the orthosteric pocket of TAS1Rs may account for the differences in binding affinity to the LBD of medaka Tas1r2a/Tas1r3 between organic acids and L-alanine, a known ligand. en-copyright= kn-copyright= en-aut-name=YamaseYuko en-aut-sei=Yamase en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Institute for Protein Research, The University of Osaka kn-affil= affil-num=6 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Taste detection kn-keyword=Taste detection en-keyword=Organic acid preference kn-keyword=Organic acid preference en-keyword=G-protein coupled receptor (GPCR) kn-keyword=G-protein coupled receptor (GPCR) en-keyword=Knockout mice kn-keyword=Knockout mice en-keyword=Surface electrostatic potential kn-keyword=Surface electrostatic potential END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=RP106917 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dorsoventral-mediated Shh induction is required for axolotl limb regeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Axolotls (Ambystoma mexicanum) exhibit a remarkable ability to regenerate limbs. Classical experiments have suggested that contact between cells derived from distinct orientations?dorsal, ventral, anterior, and posterior?within the regenerating blastema is necessary for accurate limb pattern formation. However, the molecular basis for this requirement has remained largely unknown. Here, we demonstrate that both dorsal and ventral tissues are required for limb formation via induction of Shh expression, which plays a crucial role in limb patterning. Using the accessory limb model, we induced position-specific blastemas lacking cells derived from a single orientation (anterior, posterior, dorsal, or ventral). Limb patterning occurred only in blastemas containing both dorsal- and ventral-derived cells. We further observed that Shh expression requires dorsoventral contact within a blastema, highlighting the necessity of dorsoventral contact for inducing Shh expression. Additionally, we identified WNT10B and FGF2 as dorsal- and ventral-mediated signals, respectively, that create the inductive environment for Shh expression. Our findings clarify the role of dorsal and ventral cells in inducing Shh, a mechanism that has rarely been studied in the context of limb regeneration and pattern formation. This model provides new insights into how cells with different positional identities drive the regeneration process. en-copyright= kn-copyright= en-aut-name=YamamotoSakiya en-aut-sei=Yamamoto en-aut-mei=Sakiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurukawaSaya en-aut-sei=Furukawa en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhashiAyaka en-aut-sei=Ohashi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SatohAkira en-aut-sei=Satoh en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=3 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=4 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=5 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=12 article-no= start-page=5742 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Specific Heat-Killed Lactic Acid Bacteria Enhance Mucosal Aminopeptidase N Activity in the Small Intestine of Aged Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aminopeptidase N (APN), an enzyme expressed in the small intestinal mucosa, is involved in dietary protein digestion. Previous studies have shown that oral administration of fermented milk containing lactic acid bacteria (LAB) enhances mucosal APN activity in young mice. This study aimed to investigate whether LAB strains stimulate mucosal APN activity in aged mice and to evaluate its relevance to age-related changes in body composition. The underlying molecular mechanisms were also explored in vitro. Experiment 1: Aged C57BL/6J mice were fed diets supplemented with heat-killed LAB strains?Enterococcus faecalis OU-23 (EF), Leuconostoc mesenteroides OU-03 (LM), or Lactiplantibacillus plantarum SNK12 (LP). Compared to the aged Control group, the ileal APN activity was significantly higher in the LP group. LP administration also elevated serum Gla-osteocalcin levels and decreased serum CTX-1 levels. Experiment 2: IEC-6 cells were co-cultured with LP that had been treated with RNase, DNase, or lysozyme. APN activity was significantly lower in cells co-cultured with DNase- or lysozyme-treated LP compared to those co-cultured with untreated LP. A specific LAB strain may enhance mucosal APN activity in the aged intestine, potentially contributing to improved bone metabolism. This effect may be mediated by bacterial DNA and peptidoglycan. en-copyright= kn-copyright= en-aut-name=TsurutaTakeshi en-aut-sei=Tsuruta en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaMami en-aut-sei=Wakisaka en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeTakumi en-aut-sei=Watanabe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishijimaAoi en-aut-sei=Nishijima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaAkihito en-aut-sei=Ikeda en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeraokaMao en-aut-sei=Teraoka en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangTianyang en-aut-sei=Wang en-aut-mei=Tianyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChenKuiyi en-aut-sei=Chen en-aut-mei=Kuiyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishinoNaoki en-aut-sei=Nishino en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Bio-Lab Co., Ltd. kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=aging kn-keyword=aging en-keyword=aminopeptidase N kn-keyword=aminopeptidase N en-keyword=bone metabolism kn-keyword=bone metabolism en-keyword=lactic acid bacteria kn-keyword=lactic acid bacteria en-keyword=small intestine kn-keyword=small intestine END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue= article-no= start-page=89 end-page=107 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=Filler Usage of 'De' in Modern Japanese Conversation kn-title=現代日本語の会話における「で」のフィラー的な使用について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=LIUYANG en-aut-sei=LIU en-aut-mei=YANG kn-aut-name=劉洋 kn-aut-sei=劉 kn-aut-mei=洋 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical efficacy and safety of endoscopic ultrasound-guided ablation therapies for pancreatic neuroendocrine tumors: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pancreatic neuroendocrine tumors (pNETs) are rare; however, they are increasingly being detected. Although surgical resection remains the standard treatment, its invasiveness has prompted interest in less invasive alternatives, particularly for small non-functional pNETs (NF-pNETs) and insulinomas.
Objectives: To evaluate the clinical efficacy and safety of endoscopic ultrasound-guided ethanol injection (EUS-EI) and radiofrequency ablation (EUS-RFA) for pNETs.
Design: A systematic review and meta-analysis.
Data sources and methods: A literature search of PubMed, MEDLINE, and Google Scholar was conducted (April 2005?April 2025). Studies were eligible if they reported clinical outcomes of EUS-EI or EUS-RFA in adult patients with insulinomas or NF-pNETs. The primary endpoints were clinical success (short-term symptom resolution or radiological response) and adverse event (AE) rates. Data were pooled using a random-effects model.
Results: Twenty-six studies were included in the meta-analysis. For insulinomas, the pooled clinical success rate was 77% (95% confidence interval (CI), 59?88) for EUS-EI and 95% (95% CI, 89?97) for EUS-RFA. The pooled incidence of total AEs was 32% (95% CI, 17?51) for EUS-EI and 25% (95% CI, 15?39) for EUS-RFA. For NF-pNETs, the pooled clinical success rates were 76% (95% CI, 54?90) for EUS-EI and 85% (95% CI, 74?92) for EUS-RFA, and the pooled incidence of total AEs was 27% (95% CI, 20?35) and 26% (95% CI, 17?38), respectively. The most common moderate or severe AEs were pancreatitis in 12 patients (7.6%) after EUS-EI, and pancreatic fluid collection in 4 patients (1.9%) and pancreatic duct stricture in 3 patients (1.4%) after EUS-RFA. One fatal case occurred in a 97-year-old patient following EUS-RFA.
Conclusion: Both EUS-EI and EUS-RFA are effective, relatively safe, and minimally invasive treatment options for pNETs. However, severe AE can occur, and careful patient selection and treatment indication are essential.

However, its clinical efficacy compared with autologous bone graft (ABG), a long-established treatment, remains unclear. This study aimed to compare the clinical outcomes of FGF-2 and ABG and to assess the impact of patient background factors on outcomes when using FGF-2.
Methods: We collected the subjects from January 2013 to September 2023. Clinical outcomes included the vertical bone defect improvement rate (VBDIR) and the probing pocket depth improvement (PPDI). Clinical outcomes between the two groups were compared using analysis of covariance (ANCOVA), adjusting for age, sex, smoking history, and hypertension. Additionally, a multilevel linear analysis was performed to assess factors influencing outcomes in FGF-2.
Results: A total of 180 sites from 141 patients (FGF-2: 150 sites; ABG: 30 sites) were evaluated. Both VBDIR and PPDI significantly improved postoperatively in both groups. There were no significant differences in clinical outcomes between FGF-2 and ABG. In FGF-2, smoking history was positively associated, while the preoperative bone defect angle (BDA) was negatively associated with clinical outcomes.
Conclusions: FGF-2 might exhibit clinical outcomes comparable to those of ABG, suggesting it is a clinically viable alternative for vertical bone defects. When using FGF-2, patient-specific factors such as smoking history and preoperative BDA should be considered carefully.

The pathophysiology involves fluid leakage from the choroidal capillaries, known as the choriocapillaris, into the subretinal space through sites of damage in the retinal pigment epithelium. This case report discusses the underlying causes of central serous chorioretinopathy-like findings in minimal change nephrotic syndrome.

The patient was a 33-year-old woman who developed nephrotic syndrome that was confirmed to be minimal change disease by renal biopsy. She experienced two major relapses of nephrotic syndrome at the ages of 36 and 41 years. She also had a minor relapse at the age of 37 years, five months after the first major relapse at the age of 36 years, as well as four additional minor relapses at the ages of 44, 46, 50, and 51 years. The onset of central serous chorioretinopathy-like manifestations, which were localized to the left eye, occurred three months after the initial onset of nephrotic syndrome at the age of 33 years. Two subsequent episodes of relapse of central serous chorioretinopathy-like manifestations were observed in both eyes at intervals of five months and one month, respectively, after major relapses of nephrotic syndrome at the ages of 36 and 41 years. Thereafter, she did not develop further central serous chorioretinopathy-like manifestations.

She discontinued oral prednisolone at the age of 54 years and experienced no further relapses of nephrotic syndrome through her latest visit at the age of 61 years. She maintained normal renal function and good visual acuity in both eyes. The long-term, consistent temporal association between episodes of central serous chorioretinopathy and the onset and relapses of minimal change nephrotic syndrome is strongly supported by longitudinal clinical observations spanning 28 years. This parallel course suggests a possible shared pathophysiological mechanism or common triggering factors underlying both diseases. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=central serous chorioretinopathy kn-keyword=central serous chorioretinopathy en-keyword=corticosteroid kn-keyword=corticosteroid en-keyword=cyclosporine kn-keyword=cyclosporine en-keyword=fluorescein angiography kn-keyword=fluorescein angiography en-keyword=minimal change disease kn-keyword=minimal change disease en-keyword=minimal change nephrotic syndrome kn-keyword=minimal change nephrotic syndrome en-keyword=photoreceptor ellipsoid zone kn-keyword=photoreceptor ellipsoid zone en-keyword=renal biopsy kn-keyword=renal biopsy en-keyword=steroid-induced retinal pigment epitheliopathy kn-keyword=steroid-induced retinal pigment epitheliopathy en-keyword=steroid pulse therapy kn-keyword=steroid pulse therapy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SPRED2 suppresses the stemness of hepatocellular carcinoma through the p53/miR-506-3p/KLF4 pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: We previously reported that endogenous Sprouty-related, EVH1 domain-containing protein 2 (SPRED2), an inhibitor of the Ras/Raf/ERK-MAPK pathway, controls hepatocellular carcinoma (HCC) cell stemness by downregulating the expression of pluripotency factors, such as Nanog, c-Myc, and KLF4, in an ERK-dependent fashion. However, the exact mechanisms by which SPRED2 regulates HCC cell stemness have not been established.
Methods: Three human HCC cell lines [HepG2 (parental and SPRED2-deficient), HLE, and Hep3B] were used. Cells were transfected to downregulate or overexpress proteins. Western blot and RT-qPCR were used to evaluate the level of protein and mRNA expression. Co-immunoprecipitation and ChIP-qPCR were used to examine protein-protein interactions and the activation of gene transcription. Clinical HCC tissues were also used to validate in vitro data.
Results: KLF4 was identified as the major pluripotency factor responsible for SPRED2-mediated downregulation of HCC cell stemness and KLF4 expression was regulated by miR-506-3p. SPRED2 formed a protein complex with the tumor suppressor (p53) and upregulated miR-506 gene transcription by binding to the promoter region, resulting in subsequent downregulation of KLF4 mRNA expression. There was a negative correlation between KLF4 expression and miR-506-3p and a positive correlation between miR-506-3p expression and SPRED2 in human HCC samples, highlighting the relevance of the study findings.
Conclusions: The current study revealed a novel SPRED2/p53/miR-506-3p/KLF4 axis through which SPRED2 contributes to the suppression of HCC cell stemness and provides a potential new target to prevent HCC progression. en-copyright= kn-copyright= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoSachio en-aut-sei=Ito en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Moh-Moh-AungAye en-aut-sei=Moh-Moh-Aung en-aut-mei=Aye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangTianyi en-aut-sei=Wang en-aut-mei=Tianyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology and Drug Discovery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=p53 kn-keyword=p53 en-keyword=KLF4 kn-keyword=KLF4 en-keyword=miR-506-3p kn-keyword=miR-506-3p en-keyword=stemness kn-keyword=stemness END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue= article-no= start-page=105566 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A semi-quantitative archaeothermometer based on feldspar and volcanic glass compositions in ancient ceramics from the Kibi region, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we analyzed the chemical compositions of feldspar and volcanic glass clasts in haniwa from kofuns and Sue ware from the Sabukaze kiln site, both in the Kibi region, southwestern Japan, to estimate the thermal conditions of ceramic firing in the 5th?8th centuries CE. Based on the coexistence of molten and unmolten feldspar rims, the solidus temperatures were estimated at ? 1050°C?1150°C for haniwa and ? 1150°C?1200°C for Sue ware. Volcanic glass compositions changed systematically during firing, showing increases in K2O and decreases in Na2O. From these observations, we propose a semi-quantitative archaeothermometer using variations in the K/Na molar ratio of volcanic glass within a ceramic matrix. This approach can be applied to investigate the development of kiln-firing in the Kibi region, the existence of haniwa potters employing different firing methods, variation in heat input for producing Sue vessels of differing sizes or functions, and temperature-controlled practices in Sue ware production. en-copyright= kn-copyright= en-aut-name=NozakaToshio en-aut-sei=Nozaka en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhbayashiNaoya en-aut-sei=Ohbayashi en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaYuki en-aut-sei=Toda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnamiTaiji en-aut-sei=Anami en-aut-mei=Taiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiuraKanako en-aut-sei=Sugiura en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NozakiTakahiro en-aut-sei=Nozaki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimuraOsamu en-aut-sei=Kimura en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoNaoko en-aut-sei=Matsumoto en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SeikeAkira en-aut-sei=Seike en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Archaeology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=9 en-affil=Department of Archaeology, Okayama University kn-affil= en-keyword=Haniwa kn-keyword=Haniwa en-keyword=Sue ware kn-keyword=Sue ware en-keyword=Firing temperature kn-keyword=Firing temperature en-keyword=Kibi kn-keyword=Kibi en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=12 article-no= start-page=e095428 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of education programme to increase competency of health cadres in Indonesia: a cluster non-randomised controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives Health cadres, who assist midwives in supporting pregnant women in community settings, need to enhance their competencies in identifying risk factors and referring high-risk pregnant women to midwives for further care. Since the capabilities of these health cadres are influenced by maternal complications, an educational programme was implemented to strengthen their skills. Therefore, this study aimed to evaluate the competency of health cadres by providing a researcher-developed educational programme.
Design An open-label, cluster non-randomised controlled trial.
Setting and participants Health cadres with at least 1 year of work experience were recruited at six public health centres (PHCs) in Banjarnegara Regency, Indonesia.
Interventions Six PHCs were selected and allocated into intervention group (IG=3 PHCs) and control group (CG=3 PHCs) groups. A total of 133 female health cadres were enrolled across the selected PHCs. At each PHC, a systematic random sampling method was used to select the participants. The researchers and health professionals provided a 3-week period of theoretical and scenario-based simulations to the IG, while the CG received no education.
Outcome measures Researcher-developed questionnaires and checklists were used to assess the knowledge, skills (health assessment, communication, attitude) and confidence. The primary endpoint was competency, a total score of knowledge and skills. The outcome domains were compared between the two groups, and a linear mixed-effect model was used to account for cluster-level variation.
Results A total of 130 (97.7%) completed the study (IG:64, CG:66). The competency score showed significant improvement at endline (CG=49.5?and IG=52.5; p=0.002). The median scores for health assessment skills (CG=12?vs IG=14; p<0.001) and communication skills (CG=7?vs IG=8; p<0.001) were increased in the IG compared with the CG. Mixed-effect model indicated that groups (β (95%?CI) 2.49 (0.57 to 4.41), p=0.012), baseline knowledge (β(95%?CI) 0.73 (0.54 to 0.92), p<0.001) and midline health assessment skills (β (95%?CI) 0.54 (0.25 to 0.82), p<0.001) were significant positive predictors, while age was negatively associated with competency (β (95%?CI) ?0.20 (?0.30 to ?0.10), p<0.001)).
Conclusion Education effectively increased the competency of health cadres. A well-structured education programme is necessary for health cadres to improve and maintain their competencies in monitoring high-risk pregnant women.

However, conventional methods for identifying neoantigens, such as whole-exon sequencing and short-read RNA sequencing (RNA-seq), appear to be insufficient, and the tumor mutational burden cannot sufficiently predict ICI efficacy. In this study, we employed a proteogenomic approach using long-read RNA-seq with Pacific Biosciences Single-Molecule Real-Time Sequencing technology to analyze full-length transcripts in combination with the human leukocyte antigen ligandome. As a result, many neoantigen candidates were identified, which were unregistered in a comprehensive database, including those from non-coding regions. Additionally, we validated the responses of specific T cell receptors (TCRs) to these candidates and identified several pairs of TCRs and neoantigens. These findings highlight the presence of more diverse neoantigens than expected that cannot be identified by conventional methods. en-copyright= kn-copyright= en-aut-name=IshinoTakamasa

kn-subtitle= en-abstract= kn-abstract=Phospholipids play key roles in bone formation, with phosphatidylserine (PS) reportedly inducing more rapid mineralisation than phosphatidylcholine (PC); however, the underlying mechanisms remains unclear. This study investigated PS and PC mineralisation using experimental methods and computational chemistry. The stationary points in the potential energy surfaces of the reactions were preliminarily found using a neural network potential (PreFerred Potential in Matlantis) capable of predicting the interaction energies for arbitrary combinations of atoms, and then refined through density functional theory calculations (Gaussian16, at the B3LYP/6-31G(d,p) level of theory). When hydrolysis reactions were assumed to be the initial step in the mineralisation of phospholipids, the results were consistent with empirical analysis. PS was found to be more easily hydrolised than PC, primarily owing to the presence of a labile proton in the NH3+ group of serine that facilitates proton transfer, enhancing hydrolysis of PS at lower energy thresholds. Specifically, when a single phospholipid was considered, three distinct hydrolysis routes were identified: between serine (or choline) and phosphate, between glycerol and phosphate, and between an aliphatic carbon chain and the glycerol backbone. In particular, the initial steps of hydrolysis involved the formation of a pentavalent phosphate intermediate. When calculations were performed with two adjacent phospholipid molecules, the loosely bound proton (H+) in the NH3+ group could be readily transferred either to the P?O bond linking serine to the phosphate group; or to the P?O bond connecting the phosphate to glycerol in a neighboring PS6 molecule. These findings reveal the important roles of serine NH3+ in facilitating hydrolysis of PS, and provide insights for designing novel molecules to accelerate bone regeneration. en-copyright= kn-copyright= en-aut-name=ShibataKeisuke en-aut-sei=Shibata en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiotaniTakahumi en-aut-sei=Shiotani en-aut-mei=Takahumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChenYunhao en-aut-sei=Chen en-aut-mei=Yunhao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuriharaReina en-aut-sei=Kurihara en-aut-mei=Reina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiKatsunori en-aut-sei=Yamaguchi en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunioshiN?lson en-aut-sei=Kunioshi en-aut-mei=N?lson kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Materials Science, Waseda University kn-affil= affil-num=2 en-affil=Department of Resources and Environmental Engineering, Waseda University kn-affil= affil-num=3 en-affil=Department of Materials Science, Waseda University kn-affil= affil-num=4 en-affil=Department of Resources and Environmental Engineering, Waseda University kn-affil= affil-num=5 en-affil=Department of Resources and Environmental Engineering, Waseda University kn-affil= affil-num=6 en-affil=Department of Advanced International and Information Dentistry, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Materials Science, Waseda University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue= article-no= start-page=e2500182 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=Development and Validation of an Ipsilateral Breast Tumor Recurrence Risk Estimation Tool Incorporating Real-World Data and Evidence From Meta-Analyses: A Retrospective Multicenter Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Ipsilateral breast tumor recurrence (IBTR) remains a critical concern for patients undergoing breast-conserving surgery (BCS). Reliable risk estimation tools for IBTR risk can support personalized surgical and adjuvant treatment decisions, especially in the era of evolving systemic therapies. We aimed to develop and validate models to estimate IBTR risk.
Patients and Methods This multicenter retrospective cohort study included 8,938 women who underwent partial mastectomy for invasive breast cancer between 2008 and 2017. Prediction models were developed using Cox proportional hazards regression and validated via bootstrap resampling. Model performance was assessed using Harrell's C-index, Brier scores, calibration plots, and goodness-of-fit tests.
Results During a median follow-up of 9.0 years (IQR, 6.6-10.9), IBTR occurred in 320 patients (3.6%). The initial model, based on variables from Sanghani et al, achieved a Harrell's C-index of 0.74. Incorporating hormonal receptor status, human epidermal growth factor receptor 2 status, radiotherapy, and targeted therapy as predictors reduced the C-index to 0.65, despite their clinical relevance. Importantly, the inclusion of these factors improved calibration, demonstrating better alignment between predicted and observed IBTR probabilities. Although the hazard ratios (HRs) for radiotherapy aligned with the Early Breast Cancer Trialists’ Collaborative Group meta-analyses (MA), those for chemotherapy and endocrine therapy showed slight differences. Therefore, HRs from the MA were used to represent treatment effects in our model.
Conclusion We have developed and internally validated a new risk estimation model for IBTR using Cox regression and bootstrap methods. A Web-based risk estimation tool is now available to facilitate individualized risk assessment and treatment planning. en-copyright= kn-copyright= en-aut-name=SagaraYasuaki en-aut-sei=Sagara en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaAtsushi en-aut-sei=Yoshida en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraYuri en-aut-sei=Kimura en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshitobiMakoto en-aut-sei=Ishitobi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoYuka en-aut-sei=Ono en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakadaKoji en-aut-sei=Takada en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoYuri en-aut-sei=Ito en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OsakoTomo en-aut-sei=Osako en-aut-mei=Tomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakaiTakehiko en-aut-sei=Sakai en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Breast and Thyroid Surgical Oncology, Hakuaikai Sagara Hospital kn-affil= affil-num=2 en-affil=Department of Breast Surgical Oncology, St Luke's International Hospital kn-affil= affil-num=3 en-affil=Department of Breast Surgical Oncology, The Cancer Institute Hospital of JFCR kn-affil= affil-num=4 en-affil=Department of Breast Surgery, Osaka Habikino Medical Center kn-affil= affil-num=5 en-affil=Department of Radiation Oncology and Image-Applied Therapy, Kyoto University kn-affil= affil-num=6 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Breast Surgical Oncology, Osaka Metropolitan University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Medical Statistics, Osaka Medical and Pharmaceutical University kn-affil= affil-num=10 en-affil=Division of Pathology, The Cancer Institute of Japanese Foundation for Cancer Research kn-affil= affil-num=11 en-affil=Department of Breast Surgical Oncology, The Cancer Institute Hospital of JFCR kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=e101143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic Topical Application (ETA) Therapy for Refractory Overactive Bladder: A First-in-Human Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Refractory overactive bladder (OAB) remains a clinical challenge despite established therapies, such as anticholinergics, β3-agonists, and intradetrusor botulinum toxin (BTX). Emerging evidence suggests that sensory mechanisms within the bladder, including those involving the trigone where superficial afferent networks are present, may contribute to persistent urinary urgency and frequency in some patients. Although intradetrusor BTX injection is effective in selected patients, its impact on these superficial pathways may be limited because the injected drug predominantly distributes within the detrusor. Endoscopic topical application (ETA) therapy delivers BTX directly to the trigone under air cystoscopy, potentially providing targeted modulation of sensory hyperexcitability. We report a 72-year-old woman with long-standing refractory OAB who experienced only partial improvement with repeated intradetrusor BTX injections but achieved clinically meaningful symptom relief after ETA therapy. Nocturia, urgency, urgency urinary incontinence, and voided volume were improved, with no complications other than transient postoperative urethral pain. This case suggests that ETA therapy may represent a promising sensory-focused option for refractory OAB. en-copyright= kn-copyright= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiharaMasahiro en-aut-sei=Sugihara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuiYosuke en-aut-sei=Mitsui en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeToyohiko en-aut-sei=Watanabe en-aut-mei=Toyohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Nishi Fukuyama Hospital kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bladder trigone kn-keyword=bladder trigone en-keyword=botulinum toxin kn-keyword=botulinum toxin en-keyword=endoscopic topical application kn-keyword=endoscopic topical application en-keyword=new drug delivery systems kn-keyword=new drug delivery systems en-keyword=refractory overactive bladder kn-keyword=refractory overactive bladder END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page=9991157 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knowledge and Attitudes Toward Pain Management Among Nurses in University-Affiliated Hospitals in Western Japan: A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pain is a major global concern. Nurses’ knowledge and attitudes toward pain management are critical determinants of pain care quality and patient outcomes, making them essential for effective clinical practice.
Objective: This study aimed to assess nurses’ pain management knowledge and attitudes using the Japanese version of the Knowledge and Attitudes Survey Regarding Pain (J-KASRP), applied for the first time in Japan, and to examine how background factors affect these aspects.
Methods: A descriptive, cross-sectional survey was conducted with 1589 nurses in three university-affiliated hospitals in Western Japan. Data were collected using a questionnaire capturing sociodemographic information and the J-KASRP. Descriptive statistics, t-tests, one-way ANOVA, and effect size were used to analyze J-KASRP scores and subdomains. Tukey’s honestly significant difference test was applied for post hoc comparisons across clinical experience patterns.
Results: Of 1001 respondents, 856 valid responses (85.5%) were analyzed. The mean age was 30.1?years (SD?=?8.3), and the mean total correct response rate for the J-KASRP was 59.8%; only 1.3% scored ??80%. Cancer-related pain had the lowest J-KASRP subdomain score (42.5%, SD = 20.3%). Higher total J-KASRP scores were found for those with a higher level of education, prior clinical pain education, and recent opioid administration experience (all p < 0.001, effect size > 0.2). In an exploratory pattern analysis, regardless of education level, respondents with both education and opioid administering experience had the highest total and pharmacology subdomains’ scores. No significant differences in cancer-related pain subdomain were observed across patterns of clinical experiences.
Conclusions: This first application of the J-KASRP in Japan revealed that nurses’ pain management knowledge and attitudes need to be strengthened, especially for cancer-related pain and opioid pharmacology. The study findings highlight the importance of pain management strengthening education and training to enhance nurses’ evidence-based knowledge and clinical competence. en-copyright= kn-copyright= en-aut-name=XiMengyao en-aut-sei=Xi en-aut-mei=Mengyao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KajiwaraYuki en-aut-sei=Kajiwara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiramatsuTakako en-aut-sei=Hiramatsu en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University, kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nursing, Kawasaki Medical School Hospital kn-affil= affil-num=4 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=knowledge andattitudes kn-keyword=knowledge andattitudes en-keyword=nurses kn-keyword=nurses en-keyword=painmanagement kn-keyword=painmanagement END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=11 article-no= start-page=1023 end-page=1032 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=Bioconversion and Metabolic Fate of the n-1 Polyunsaturated Fatty Acids, 6,9,12,15- Hexadecatetraenoic (C16:4 n-1) and 8,11,14,17- Octadecatetraenoic (C18:4 n-1) Acids, in HepG2 Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fish oil contains not only major fatty acids with double bonds at the n-3, n-6, n-7, and n-9 positions but also those with a double bond at the n-1 position, such as 6,9,12,15-hexadecatetraenoic acid (C16:4 n-1; HDTA). However, intracellular bioconversion and metabolic fate of n-1 polyunsaturated fatty acids (PUFA) remain unclear. Therefore, in this study, we aimed to assess the intracellular bioconversion and metabolic fate of HDTA and its metabolite, 8,11,14,17- octadecatetraenoic acid (C18:4 n-1; ODTA), using HepG2 cells. Based on the results of cell viability and cytotoxicity assays for HDTA and ODTA, the concentration of each fatty acid supplemented in the experiments was set at 10 μM. HepG2 cell culture with HDTA revealed C20:4 n-1 as a new HDTA metabolite, along with previously reported ODTA. Our findings suggest that the HDTA taken up by HepG2 cells undergoes elongation to form ODTA and C20:4 n-1. Following supplementation with HDTA, ODTA, and 5,8,11,14,17-eicosapentaenoic acid (C20:5 n-3; EPA), fatty acids disappeared from the culture medium within 24 h. Notably, the total relative level of HDTA and its metabolites, including ODTA and C20:4 n-1 in HDTA- and ODTA-supplemented cells were significantly lower than the total relative level of EPA and its metabolites, including 7,10,13,16,19-docosapentaenoic acid (C22:5 n-3), C24:6 n-3, and 4,7,10,13,16,19-docosahexaenoic acid (C22:6 n-3) in the EPA-supplemented cells. Except for a portion that was intracellularly elongated, most HDTA was taken up by HepG2 cells and may undergo rapid fatty acid β-oxidation. However, RNA-sequencing and real-time polymerase chain reaction analysis revealed no significant changes in fatty acid β-oxidation?related gene expression levels in HDTA-supplemented cells. Collectively, these results provide novel insights into the intracellular bioconversion mechanisms and metabolic fate of HDTA and ODTA in HepG2 cells, suggesting that the metabolic fate of n-1 PUFA is distinct from that of common PUFA. en-copyright= kn-copyright= en-aut-name=SugimotoKoki en-aut-sei=Sugimoto en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiguchiHideto en-aut-sei=Nishiguchi en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HosomiRyota en-aut-sei=Hosomi en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanizakiToshifumi en-aut-sei=Tanizaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsushimaTadahiro en-aut-sei=Tsushima en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BabaNaomichi en-aut-sei=Baba en-aut-mei=Naomichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MisawaYoshihisa en-aut-sei=Misawa en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MurakamiYuki en-aut-sei=Murakami en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KandaSeiji en-aut-sei=Kanda en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FukunagaKenji en-aut-sei=Fukunaga en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Faculty of Food and Nutritional Sciences, Toyo University kn-affil= affil-num=2 en-affil=Faculty of Chemistry, Materials, and Bioengineering, Kansai University kn-affil= affil-num=3 en-affil=Faculty of Chemistry, Materials, and Bioengineering, Kansai University kn-affil= affil-num=4 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=5 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=6 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=7 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=8 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Hygiene and Public Health, Kansai Medical University kn-affil= affil-num=11 en-affil=Department of Hygiene and Public Health, Kansai Medical University kn-affil= affil-num=12 en-affil=Faculty of Chemistry, Materials, and Bioengineering, Kansai University kn-affil= en-keyword=n-1 polyunsaturated fatty acids kn-keyword=n-1 polyunsaturated fatty acids en-keyword=hexadecatetraenoic acid kn-keyword=hexadecatetraenoic acid en-keyword=octadecatetraenoic acid kn-keyword=octadecatetraenoic acid en-keyword=HepG2 kn-keyword=HepG2 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=29639 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250813 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Single cell spatial transcriptomics links Wnt signaling disruption to extracellular matrix development in a cleft palate model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite advances in understanding the morphological disruptions that lead to defects in palate formation, the precise perturbations within the signaling microenvironment of palatal clefts remain poorly understood. To explore in greater depth the genomic basis of palatal clefts, we designed and implemented the first single cell spatial RNA-sequencing study in a cleft palate model, utilizing the Pax9?/? murine model at multiple developmental timepoints, which exhibits a consistent cleft palate defect. Visium HD, an emerging platform for true single-cell resolution spatially resolved transcriptomics, was employed using custom bins of 2?×?2 μm spatial gene expression data. Validation of spatial gene expression was then validated using custom designed Xenium In Situ mRNA spatial profiling and RNAscope Multiplex assays. Functional enrichment analysis revealed a palate cell-specific perturbation in Wnt signaling effector function in tandem with disrupted expression of extracellular matrix genes in developing mesenchyme. As a key step toward laying the framework for identifying key molecular targets these data can be used for translational studies aimed at developing effective therapies for human palatal clefts. en-copyright= kn-copyright= en-aut-name=Pi?aJeremie Oliver en-aut-sei=Pi?a en-aut-mei=Jeremie Oliver kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RajuResmi en-aut-sei=Raju en-aut-mei=Resmi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=StipanoEvan en-aut-sei=Stipano en-aut-mei=Evan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MyoAye Chan en-aut-sei=Myo en-aut-mei=Aye Chan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChattarajParna en-aut-sei=Chattaraj en-aut-mei=Parna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FurukawaMasae en-aut-sei=Furukawa en-aut-mei=Masae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=D’SouzaRena N. en-aut-sei=D’Souza en-aut-mei=Rena N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=2 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=3 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=4 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=5 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Molecular Biology and Biochemistry, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Molecular Biology and Biochemistry, Okayama University kn-affil= affil-num=7 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=8 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=9 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= en-keyword=Spatial biology kn-keyword=Spatial biology en-keyword=Cleft palate kn-keyword=Cleft palate en-keyword=Genomics kn-keyword=Genomics en-keyword=Single cell kn-keyword=Single cell en-keyword=Gene expression kn-keyword=Gene expression en-keyword=Profiling kn-keyword=Profiling en-keyword=Extracellular matrix kn-keyword=Extracellular matrix en-keyword=Wnt kn-keyword=Wnt en-keyword=Transcriptome kn-keyword=Transcriptome END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=2 article-no= start-page=E82 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crystal structure of tris[4-(3,4-dimethoxythiophen-2-yl)phenyl]amine en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the title compound tris?[4-(3,4-di?meth?oxy?thio?phen-2-yl)phen?yl]amine (DMOT-TPA), C36H33NO6S3, the central nitro?gen atom shows no pyramidalization, with the three para-phenyl?ene rings arranged in a propeller-like geometry.

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=5 cd-vols= no-issue=4 article-no= start-page=74 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Integrated QGIS-Based Evacuation Route Optimization Approach for Disaster Preparedness Against Urban Flood in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Urban inland flooding has become a serious problem in many cities because heavy rain often exceeds the capacity of drainage systems. In Japan, GIS-based evacuation maps are commonly used to support disaster preparedness, but they still have several limitations. In particular, they do not avoid flooded road segments and cannot generate multiple evacuation options at the same time. This study proposes an improved evacuation route method using the free and open-source software QGIS. The method combines flood-depth data with road network processing to remove roads where the predicted water depth is higher than 0.5 m. It also provides several evacuation paths to different shelters at the same time. A case study in Kurashiki City, Okayama Prefecture, demonstrates that about 1.37% of the road network becomes unusable during an inland-flood scenario. Several existing evacuation routes also pass through hazardous areas, but the QGIS-based method avoids these areas in most cases. Since the workflow uses only built-in QGIS functions and does not require programming or plug-ins, it is easy to reproduce and apply in other regions. This study offers a practical and low-cost method to support inland-flood evacuation planning for local governments. en-copyright= kn-copyright= en-aut-name=PanWenliang en-aut-sei=Pan en-aut-mei=Wenliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PanShijun en-aut-sei=Pan en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetoJunko en-aut-sei=Kaneto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaKeisuke en-aut-sei=Yoshida en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaSatoshi en-aut-sei=Nishiyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=evacuation route kn-keyword=evacuation route en-keyword=hazard mapping kn-keyword=hazard mapping en-keyword=inland flood kn-keyword=inland flood en-keyword=land use analysis kn-keyword=land use analysis en-keyword=QGIS kn-keyword=QGIS END start-ver=1.4 cd-journal=joma no-vol=193 cd-vols= no-issue= article-no= start-page=118724 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=Deciphering the structural impact of norepinephrine analog radiopharmaceuticals on organic cation transporter affinity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Previous studies have investigated the kinetics and affinities of norepinephrine transporter (NET)-targeting radiotracers, including [123I]MIBG, but the role of organic cation transporters (OCTs) remains unclear. This study aimed to evaluate how the structural design of selective NET-targeting tracers affects OCT-mediated non-specific uptake, identifying factors influencing both NET and OCT affinity.
Methods: Cellular uptake assays were conducted using SK-N-SH cells expressing human NET, and human OCT1-, OCT2-, and OCT3-expressing cells with [3H]norepinephrine, [3H]MPP+, and [131I]MIBG. Competitive uptake assays used non-radioactive reference compounds for several NET-targeting radiopharmaceuticals (MIBG, HED, EPI, PHEN, LMI1195, and PHPG), along with a new PET radiotracer [18F]AF78, and its two analogs with meta-iodide [18F]AF78(I) or hydroxyl group [18F]AF78(OH). Dynamic PET imaging in non-human primates assessed the in vivo uptake of [18F]AF78 after NET inhibition with desipramine.
Results: Monoamine-based tracers (EPI, PHEN, HED) exhibited high NET selectivity with minimal OCTs interaction, while guanidine-containing tracers (e.g., MIBG, LMI1195) displayed substantial OCTs affinity. Lower lipophilicity in guanidine-containing compounds, influenced by substitutions on the benzene ring (e.g., PHPG, AF78), correlated with weaker OCT interactions. PET imaging confirmed that cardiac uptake of [18F]AF78 is sensitive to desipramine pretreatment (***P? Conclusion: This study highlights the critical influence of the compounds’ chemical structure on NET and OCT affinities. Structural modifications that reduce OCT-mediated uptake while maintaining high NET affinity could improve the specificity and theranostic potential of NET-targeting ligands. These findings provide insights for designing next-generation radiotracers with enhanced selectivity and clinical utility. en-copyright= kn-copyright= en-aut-name=M?hligSaskia en-aut-sei=M?hlig en-aut-mei=Saskia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChenXinyu en-aut-sei=Chen en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TutovAnna en-aut-sei=Tutov en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NoseNaoko en-aut-sei=Nose en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LapaConstantin en-aut-sei=Lapa en-aut-mei=Constantin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WernerRudolf A. en-aut-sei=Werner en-aut-mei=Rudolf A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DeckerMichael en-aut-sei=Decker en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Nuclear Medicine and Comprehensive Heart Failure Center, University Hospital W?rzburg kn-affil= affil-num=2 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=3 en-affil=Pharmaceutical and Medicinal Chemistry, Institute of Pharmacy and Food Chemistry, University of W?rzburg kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=6 en-affil=Department of Nuclear Medicine, LMU Hospital, Ludwig-Maximilians-University of Munich kn-affil= affil-num=7 en-affil=Pharmaceutical and Medicinal Chemistry, Institute of Pharmacy and Food Chemistry, University of W?rzburg kn-affil= affil-num=8 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Norepinephrine transporter kn-keyword=Norepinephrine transporter en-keyword=Organic cation transporter kn-keyword=Organic cation transporter en-keyword=Neuroendocrine tumor kn-keyword=Neuroendocrine tumor en-keyword=Competitive cell uptake kn-keyword=Competitive cell uptake en-keyword=PET radiotracer kn-keyword=PET radiotracer END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue= article-no= start-page=100857 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A multi-institutional dummy run on segmentation variability and plan quality of stereotactic body radiotherapy for oligometastatic disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and purpose: Oligometastatic disease represents limited metastatic burden, and local ablative therapies such as stereotactic body radiotherapy (SBRT) may improve survival. However, inter-institutional variability in target segmentation and treatment planning can compromise treatment quality. This study aimed to evaluate the segmentation variability and dose distribution quality of SBRT in oligometastatic settings using a multi-institutional dummy run approach.
Methods and materials: Sixty-nine institutions were provided with two anonymized cases of adrenal and spine metastases to delineate targets and organs at risk (OARs) and create intensity-modulated radiotherapy plans following a protocol. Variability was quantified using the Dice similarity coefficient (DSC), Hausdorff distance, and mean distance to agreement. Plan qualities were assessed using the Paddick conformity index, modified gradient index, and a new three-dimensional conformity?gradient index (3D-CGI). Knowledge-based planning (KBP) was applied to explore potential improvements in OAR sparing.
Results: All submitted plans met protocol dose constraints. However, substantial segmentation variability was observed, particularly for the spine case. Among 136 plans, 79% demonstrated acceptable conformity and dose gradients, with 3D-CGI < 6 correlating with favorable distributions. Mean DSC was 0.93 for the clinical target volume and 0.76 for the cauda equina, which showed the highest variability. KBP reduced OAR doses for the adrenal case but showed limited impact for the spine case.
Conclusions: Although dose constraints were achieved, segmentation variability remained substantial, particularly for the cauda equina in the spine case. These findings emphasize inter-institutional differences and the need for standardization and tools to improve SBRT consistency. en-copyright= kn-copyright= en-aut-name=HirashimaHideaki en-aut-sei=Hirashima en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoYukinori en-aut-sei=Matsuo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshikuraSatoshi en-aut-sei=Ishikura en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraMitsuhiro en-aut-sei=Nakamura en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishibuchiIkuno en-aut-sei=Nishibuchi en-aut-mei=Ikuno kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawaharaDaisuke en-aut-sei=Kawahara en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimadaYoshihisa en-aut-sei=Shimada en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakaharaYoshiro en-aut-sei=Nakahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=ShikamaNaoto en-aut-sei=Shikama en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WatanabeShun-ichi en-aut-sei=Watanabe en-aut-mei=Shun-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OkamotoIsamu en-aut-sei=Okamoto en-aut-mei=Isamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IshibaToshiyuki en-aut-sei=Ishiba en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HaraFumikata en-aut-sei=Hara en-aut-mei=Fumikata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MizowakiTakashi en-aut-sei=Mizowaki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Radiation Oncology and Image-Applied Therapy, Graduate School of Medicine, Kyoto University kn-affil= affil-num=2 en-affil=Department of Radiation Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Radiation Oncology, St. Luke’s International Hospital, St. Luke’s International University kn-affil= affil-num=4 en-affil=Department of Advanced Medical Physics, Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Department of Radiation Oncology, Graduate School of Biomedical Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Radiation Oncology, Graduate School of Biomedical Health Sciences, Hiroshima University kn-affil= affil-num=7 en-affil=Department of Surgery, Tokyo Medical University kn-affil= affil-num=8 en-affil=Department of Respiratory Medicine, Kitasato University Hospital kn-affil= affil-num=9 en-affil=Medical Physics Laboratory, Division of Health Science, Graduate School of Medicine, The University of Osaka kn-affil= affil-num=10 en-affil=Department of Radiation Oncology, Juntendo University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Thoracic Surgery, National Cancer Center Hospital kn-affil= affil-num=12 en-affil=Department of Respiratory Medicine, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=13 en-affil=Department of Breast Surgery, Institute of Science Tokyo kn-affil= affil-num=14 en-affil=Department of Breast Oncology, Aichi Cancer Center Hospital kn-affil= affil-num=15 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=16 en-affil=Department of Radiation Oncology and Image-Applied Therapy, Graduate School of Medicine, Kyoto University kn-affil= en-keyword=Oligometastatic disease kn-keyword=Oligometastatic disease en-keyword=Dummy run kn-keyword=Dummy run en-keyword=Segmentation variability kn-keyword=Segmentation variability en-keyword=Dose distribution accuracy kn-keyword=Dose distribution accuracy END start-ver=1.4 cd-journal=joma no-vol=684 cd-vols= no-issue= article-no= start-page=131245 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Longitudinal-field fidelity susceptibility analysis of the ?1-?2 transverse-field Ising model around ?2??1 ? 0.5 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The square-lattice ?1-?2 transverse-field (TF) Ising model was investigated with the exact diagonalization (ED) method. In order to analyze the TF-driven phase transition, we applied the longitudinal-field fidelity susceptibility ?(?)?, which is readily evaluated via the ED scheme. Here, the longitudinal field couples with the absolute value of the magnetic moment |?| rather than the raw ? so that the remedied fidelity susceptibility exhibits a peak around the critical point; note that the spontaneous magnetization does not appear for the finite-size systems. As a preliminary survey, the modified fidelity susceptibility ?(?)? is applied to the analysis of criticality for ?2 = 0, where a number of preceding results are available. Thereby, properly scaling the distance from the multi-criticality, ? = 0.5??2, the ?(?)? data were cast into the crossover-scaling formula, and the multi-critical exponent for ?(?)? is estimated. The result is cross-checked by the numerically evaluated ?-function behavior. en-copyright= kn-copyright= en-aut-name=NishiyamaYoshihiro en-aut-sei=Nishiyama en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Physics, Faculty of Science, Okayama University kn-affil= en-keyword=05.50.+q 05.10.-a 05.70.Jk 64.60.-i kn-keyword=05.50.+q 05.10.-a 05.70.Jk 64.60.-i 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=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.

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=135 cd-vols= no-issue= article-no= start-page=107077 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=Inhibitory effect of cyclodextran on the induction of dental caries by Streptococcus mutans en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cyclodextrans (CIs) are cycloisomaltooligosaccharides that are known to function as dextran analogues and are possible inhibitors of dental plaque formation. CIs have a structure in which 7 to 12 glucose molecules are cyclically linked by α-1,6 bonds. We examined the inhibitory effects of CIs on the induction of dental caries by Streptococcus mutans. The inhibitory effects for bacterial growth, anti-enzymatic activity, and biofilm formation were analyzed. Additionally, the inhibitory effect of CIs on the induction of dental caries was investigated using a rat caries model. The presence of CIs resulted in reduced bacterial growth and biofilm formation. Kinetic analysis of the results showed that the inhibitory effect of CIs on anti-enzymatic activity is competitive. Furthermore, the caries scores with CIs were lower than those without CIs in both diet and drinking experiments. These results suggest that CIs possess strong anticaries activity and may be useful as a dietary supplement. en-copyright= kn-copyright= en-aut-name=AsaumiHaruka en-aut-sei=Asaumi en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraSakuya en-aut-sei=Matsuura en-aut-mei=Sakuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoKana en-aut-sei=Goto en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuokaDaiki en-aut-sei=Matsuoka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TabataKeiko en-aut-sei=Tabata en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakaShuhei en-aut-sei=Naka en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Matsumoto-NakanoMichiyo en-aut-sei=Matsumoto-Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Streptococcus mutans kn-keyword=Streptococcus mutans en-keyword=glucosyltransferase kn-keyword=glucosyltransferase en-keyword=dental caries kn-keyword=dental caries en-keyword=cyclodextran kn-keyword=cyclodextran en-keyword=animal experiments kn-keyword=animal experiments END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99936 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=Redistribution of fragmented mitochondria ensures symmetric organelle partitioning and faithful chromosome segregation in mitotic mouse zygotes en-subtitle= kn-subtitle= en-abstract= kn-abstract=In cleavage-stage embryos, preexisting organelles partition evenly into daughter blastomeres without signi?cant cell growth after symmetric cell division. The presence of mitochondrial DNA within mitochondria and its restricted replication during preimplantation development makes their inheritance particularly important. While chromosomes are precisely segregated by the mitotic spindle, the mechanisms controlling mitochondrial partitioning remain poorly understood. In this study, we investigate the mechanism by which Dynamin-related protein 1 (Drp1) controls the mitochondrial redistribution and partitioning during embryonic cleavage. Depletion of Drp1 in mouse zygotes causes marked mitochondrial aggregation, and the majority of embryos arrest at the 2 cell stage. Clumped mitochondria are located in the center of mitotic Drp1-depleted zygotes with less uniform distribution, thereby preventing their symmetric partitioning. Asymmetric mitochondrial inheritance is accompanied by functionally inequivalent blastomeres with biased ATP and endoplasmic reticulum Ca2+ levels. We also find that marked mitochondrial centration in Drp1-depleted zygotes prevents the assembly of parental chromosomes, resulting in chromosome segregation defects and binucleation. Thus, mitochondrial fragmentation mediated by Drp1 ensures proper organelle positioning and partitioning into functional daughters during the first embryonic cleavage. en-copyright= kn-copyright= en-aut-name=GekkoHaruna en-aut-sei=Gekko en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomuraRuri en-aut-sei=Nomura en-aut-mei=Ruri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuzuharaDaiki en-aut-sei=Kuzuhara en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KaneyasuMasato en-aut-sei=Kaneyasu en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosekiGenpei en-aut-sei=Koseki en-aut-mei=Genpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AdhikariDeepak en-aut-sei=Adhikari en-aut-mei=Deepak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MioYasuyuki en-aut-sei=Mio en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=CarrollJohn en-aut-sei=Carroll en-aut-mei=John kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KonoTomohiro en-aut-sei=Kono en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Reproductive Centre, Mio Fertility Clinic kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Development and Stem Cell Program and Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University kn-affil= affil-num=7 en-affil=Reproductive Centre, Mio Fertility Clinic kn-affil= affil-num=8 en-affil=Development and Stem Cell Program and Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University kn-affil= affil-num=9 en-affil=Department of Bioscience, Tokyo University of Agriculture kn-affil= affil-num=10 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=2 article-no= start-page=222 end-page=225 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ethical Use of Cadaveric Images in Anatomical Textbooks, Atlases, and Journals: A Consensus Response From Authors and Editors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose. Cadaveric photos and drawings made from dissections of cadavers have been used in anatomy textbooks and atlases for hundreds of years. They are invaluable for anatomy students and clinical/surgical practitioners. The IFAA guidelines should not restrict the use of those older books; to do so would infringe the rights of those seeking knowledge from these resources. As the images in such textbooks and atlases are anonymized and are used for teaching and research, and the donors and their families are informed about this before the donation, we believe no additional consent is needed. It is impossible to separate educational from “commercial” usage entirely in any situation, e.g., publications from publishers and the use of cadavers in medical schools. Therefore, our best efforts to avoid unethical use of cadaveric images by following traditional consent processes are still needed so that more people will reap the benefits from them. As senior textbook/atlas authors/editors from over 10 countries, we believe that using cadaveric images in anatomy textbooks is appropriate, and no additional consent should be necessary. Such usage falls within the good faith of professionals using these invaluable gifts. en-copyright= kn-copyright= en-aut-name=IwanagaJoe en-aut-sei=Iwanaga en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimHee‐Jin en-aut-sei=Kim en-aut-mei=Hee‐Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkitaKeiichi en-aut-sei=Akita en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LoganBari M. en-aut-sei=Logan en-aut-mei=Bari M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HutchingsRalph T. en-aut-sei=Hutchings en-aut-mei=Ralph T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OttoneNicol?s en-aut-sei=Ottone en-aut-mei=Nicol?s kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NonakaYoichi en-aut-sei=Nonaka en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AnandMahindra en-aut-sei=Anand en-aut-mei=Mahindra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BurnsDanny en-aut-sei=Burns en-aut-mei=Danny kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SinghVishram en-aut-sei=Singh en-aut-mei=Vishram kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Peris‐CeldaMaria en-aut-sei=Peris‐Celda en-aut-mei=Maria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Martinez‐SorianoFrancisco en-aut-sei=Martinez‐Soriano en-aut-mei=Francisco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ApaydinNihal en-aut-sei=Apaydin en-aut-mei=Nihal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HannaAmgad en-aut-sei=Hanna en-aut-mei=Amgad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshiokaNobutaka en-aut-sei=Yoshioka en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Fernandez‐MirandaJuan en-aut-sei=Fernandez‐Miranda en-aut-mei=Juan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HurMi‐Sun en-aut-sei=Hur en-aut-mei=Mi‐Sun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=ShojaMohammadali M. en-aut-sei=Shoja en-aut-mei=Mohammadali M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=SaremiFarhood en-aut-sei=Saremi en-aut-mei=Farhood kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=ReinaFrancisco en-aut-sei=Reina en-aut-mei=Francisco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=TabiraYoko en-aut-sei=Tabira en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=CarreraAnna en-aut-sei=Carrera en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=SprattJonathan D. en-aut-sei=Spratt en-aut-mei=Jonathan D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=HoS.

Multiple factors, including genetic factors, may underlie this variability; however, the specific determinants remain unclear. To identify genes affecting AAO, we have conducted a genome-wide association study in Japanese patients with ALS (discovery cohort: n?=?1808; replication cohort: n?=?207). Here, we show that the minor A allele of rs113161727 at the ADAM29-GPM6A locus is associated with a younger AAO in the discovery cohort (effect, -4.27 years; p?=?4.60 × 10-8); this finding has been confirmed in the replication cohort (p?=?0.0068) and meta-analysis (p?=?1.08 × 10?9). Among 65 ALS patients with a SOD1 mutation, the AAO has been found to be 10.2 years younger in those with the A allele than in those without it (p?=?0.002). This variant correlates with GPM6A upregulation in iPSC-derived motor neurons, suggesting GPM6A as a candidate AAO modifier. Overall, our study highlights the impact of genetic modifiers on ALS heterogeneity and provides a potential target for delaying disease onset. en-copyright= kn-copyright= en-aut-name=NakamuraRyoichi

Central Retinal Vein Occlusion With Differential Long-Term Outcomes Following Cardiac Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bilateral central retinal vein occlusion (CRVO) is rare and is associated with systemic diseases such as hypertension, diabetes, dyslipidemia, and coagulopathy. In this study, we showed that the sequential development of bilateral CRVO in an elderly patient was related to increased venous pressure in the right heart system. A 71-year-old man developed CRVO in the right eye, and one year later, he developed CRVO in the left eye. He had undergone pacemaker implantation for sick sinus syndrome 10 years earlier and had started hemodialysis three months prior for chronic renal failure, probably caused by hypertensive nephrosclerosis. The right CRVO resulted in neovascular glaucoma and loss of light perception despite intensive treatment with panretinal laser photocoagulation, intravitreal bevacizumab injection, and additional laser therapy. In contrast, the left CRVO remained at an impending stage, was treated only with panretinal laser photocoagulation, and had a favorable outcome for 11 years until his death. In retrospect, half a year after the onset of left CRVO, the patient underwent open-heart surgery to repair aortic, mitral, and tricuspid valve regurgitation through aortic valve replacement, mitral valve annuloplasty, and tricuspid valve annuloplasty, respectively. Based on the temporal sequence of events, elevated venous pressure due to right heart dysfunction may have contributed to the poor outcome of the right CRVO, whereas improvement of venous stasis after cardiac surgery may have led to the better long-term outcome of the left CRVO. Venous stasis in the right heart system should therefore be considered an underlying factor in the development of bilateral CRVO. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MasudaZenichi en-aut-sei=Masuda en-aut-mei=Zenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiyamaHiroki en-aut-sei=Sugiyama en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, Okayama University Hospital kn-affil= affil-num=2 en-affil=Cardiovascular Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Cardiovascular Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Cardiovascular Medicine and Center for Advanced Heart Failure, Okayama University Hospital kn-affil= en-keyword=aortic valve regurgitation kn-keyword=aortic valve regurgitation en-keyword=aortic valve replacement kn-keyword=aortic valve replacement en-keyword=bevacizumab kn-keyword=bevacizumab en-keyword=bilateral central retinal vein occlusion kn-keyword=bilateral central retinal vein occlusion en-keyword=intravitreal injection kn-keyword=intravitreal injection en-keyword=mitral valve annuloplasty kn-keyword=mitral valve annuloplasty en-keyword=mitral valve regurgitation kn-keyword=mitral valve regurgitation en-keyword=panretinal laser photocoagulation kn-keyword=panretinal laser photocoagulation en-keyword=tricuspid valve annuloplasty kn-keyword=tricuspid valve annuloplasty en-keyword=tricuspid valve regurgitation kn-keyword=tricuspid valve regurgitation END start-ver=1.4 cd-journal=joma no-vol=237 cd-vols= no-issue= article-no= start-page=113001 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=Impact of different X-ray tube positions on actual dose measurements during CT examinations -An effect of patient physique- en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dose management of patients is very important during X-ray Computed Tomography (CT) examinations, but because the patient's surface dose is inhomogeneous, it is difficult to measure the most probable value using a small passive-type dosimeter, lent to the patient. To solve this problem, our research group developed a precise dose analysis procedure in which a systematic uncertainty related to the X-ray incident direction (θin) is reduced. θin information was analyzed from CT images. However, the applicability of our procedure to actual patients with various physiques has not been examined. This study aims to propose a dose analysis procedure that can be applied to patients with various physiques, and to show its impact on dose measurement. Clinical data of 198 patients with Body Mass Index (BMI) values between 15 and 40 kg/m2 (mean value: 23.1 ± 3.8 kg/m2) who underwent chest CT scans were analyzed after dividing them into three groups based on BMI values. The absorbed dose was measured with a small-type Optically Stimulated Luminescence (OSL) dosimeter. To derive correction factors related to θin, the dependence of the actually-measured dose values of various patients on θin was analyzed. The correction coefficients were determined independently for the three groups classified by BMI values. By correcting the effect of θin, the systematic uncertainty element could be reduced, resulting in 30 % reduction of the uncertainty. Furthermore, it was found that our analysis procedure makes it possible to visualize outliers. In comparison with the expected dose values based on Computed Tomography Dose Index (CTDI) values, most of the data fell within the range of ±1.34 mGy (=1σ). However, 7 % of the data showed large deviations larger than 2σ. In conclusion, our research group has developed a procedure for measuring patient surface doses that can be applied to patients having various physiques, in which the effects of X-ray incident direction were accurately corrected. The procedure could be one solution to the problems with actual dose measurements during CT examinations, and will be useful for dose management based on the small-type dosimeter. en-copyright= kn-copyright= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaTatsuya en-aut-sei=Maeda en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakegamiKazuki en-aut-sei=Takegami en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoSota en-aut-sei=Goto en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishigamiRina en-aut-sei=Nishigami en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobayashiDaiki en-aut-sei=Kobayashi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KanazawaYuki en-aut-sei=Kanazawa en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamashitaKazuta en-aut-sei=Yamashita en-aut-mei=Kazuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KonishiTakeshi en-aut-sei=Konishi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MakiMotochika en-aut-sei=Maki en-aut-mei=Motochika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=2 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Yamaguchi University Hospital kn-affil= affil-num=4 en-affil=Faculty of Health Sciences, Kobe Tokiwa University kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=7 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=8 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=9 en-affil=Faculty of Life Science, Kumamoto University kn-affil= affil-num=10 en-affil=Department of Orthopedics, School of Medicine, Tokushima University kn-affil= affil-num=11 en-affil=MEDITEC JAPAN Co., Ltd. kn-affil= affil-num=12 en-affil=MEDITEC JAPAN Co., Ltd. kn-affil= en-keyword=Patient dosimetry kn-keyword=Patient dosimetry en-keyword=Medical diagnosis kn-keyword=Medical diagnosis en-keyword=OSL dosimeter kn-keyword=OSL dosimeter en-keyword=X-ray CT kn-keyword=X-ray CT en-keyword=Passive type radiation dosimeter kn-keyword=Passive type radiation dosimeter en-keyword=BMI kn-keyword=BMI END start-ver=1.4 cd-journal=joma no-vol=493 cd-vols= no-issue= article-no= start-page=110069 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Coast uplifted by nearby shore-parallel active submarine faults during the 2024 Mw 7.5 Noto Peninsula earthquake en-subtitle= kn-subtitle= en-abstract= kn-abstract=An Mw 7.5 earthquake occurred at 16:10 JST on January 1, 2024 at a depth of 16 km on the Noto Peninsula, central Japan. This earthquake was the second-largest intraplate earthquake recorded in Japan during 120 years of seismic observation, and it caused approximately 100 km of coastal seafloor emergence along the peninsula's northern coast. Herein, we mapped the emergence of this coastal seafloor and measured the uplift along the coast. The movement of the coastline led to the emergence of approximately 4.4 km2 of seafloor, which is continuous and probably the longest in the world. We determined the uplift distribution along the coast using the white remains of a reddish seaweed called Corallina pilulifera. Its upper limit exhibited a distinct horizontal line, effectively representing the uplift amount throughout the peninsula. Two large, uplifted regions were identified, around Cape Saruyama (5.21 m) in the west and Cape Kurasaki (2.70 m) in the north. Although active offshore submarine faults have been extensively researched, the fault traces remain poorly defined because they are primarily interpreted from seismic reflection profiles. We identified the distribution of active submarine faults using anaglyph-type stereoscopic images, confirming the subsurface deformation structure seen through the seismic reflection profiles. The main fault trace is primarily straight and contiguous with the nearby north coast. The uplift amount is greater near the active fault traces on the north side and diminishes sharply with increasing distance from these faults, indicating a southward tilt of surface uplift related to the active submarine faults. en-copyright= kn-copyright= en-aut-name=GotoHideaki en-aut-sei=Goto en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaTomoru en-aut-sei=Yamanaka en-aut-mei=Tomoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakitaTomohiro en-aut-sei=Makita en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwasaYoshiya en-aut-sei=Iwasa en-aut-mei=Yoshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OguraTakuro en-aut-sei=Ogura en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KagoharaKyoko en-aut-sei=Kagohara en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KumaharaYasuhiro en-aut-sei=Kumahara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiYasuhiro en-aut-sei=Suzuki en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AokiTatsuto en-aut-sei=Aoki en-aut-mei=Tatsuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MoriWataru en-aut-sei=Mori en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaranishiKenta en-aut-sei=Haranishi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakataTakashi en-aut-sei=Nakata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Hiroshima University kn-affil= affil-num=2 en-affil=Natural History Museum and Institute Chiba kn-affil= affil-num=3 en-affil=Hiroshima University kn-affil= affil-num=4 en-affil=University of Teacher Education Fukuoka kn-affil= affil-num=5 en-affil=Hyogo University of Teacher Education kn-affil= affil-num=6 en-affil=Yamaguchi University kn-affil= affil-num=7 en-affil=Hiroshima University kn-affil= affil-num=8 en-affil=Nagoya University kn-affil= affil-num=9 en-affil=Okayama University kn-affil= affil-num=10 en-affil=Kanazawa University kn-affil= affil-num=11 en-affil=Hiroshima University kn-affil= affil-num=12 en-affil=Hiroshima University kn-affil= affil-num=13 en-affil=Hiroshima University kn-affil= en-keyword=Active submarine fault kn-keyword=Active submarine fault en-keyword=Tectonic landform kn-keyword=Tectonic landform en-keyword=Coseismic coastal uplift kn-keyword=Coseismic coastal uplift en-keyword=Noto Peninsula kn-keyword=Noto Peninsula en-keyword=Sea of Japan kn-keyword=Sea of Japan END start-ver=1.4 cd-journal=joma no-vol=468 cd-vols= no-issue= article-no= start-page=109497 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=Surface exposure ages of middle?late Pleistocene marine and fluvial terraces along the northern and southern Sanriku coasts, Northeast Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=To estimate long-term rates of coastal uplift along the northern Pacific coast of Northeast Japan, we determined the surface exposure ages of marine and fluvial terraces based on terrestrial in situ cosmogenic radionuclide dating of exposed bedrock surfaces. Based on reinterpretation of marine and fluvial terraces, we collected samples from the northern and southern Sanriku coast. The surface exposure ages from 10Be concentrations in quartz calculated from the measured 10Be/9Be ratios commonly suggest MIS 5 and MIS 7 for the marine and fluvial terraces and averaged coastal uplift rates of ca. 0.25?±?0.15 and 0.4?mm/yr along the northern and southern Sanriku coast at intermediate timescales. The results may demonstrate different styles of crustal strain accommodation in the northern Northeast Japan arc above the subducting Pacific plate. en-copyright= kn-copyright= en-aut-name=WakasaSachi en-aut-sei=Wakasa en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiyamaTatsuya en-aut-sei=Ishiyama en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirouchiDaisuke en-aut-sei=Hirouchi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujitaNatsuko en-aut-sei=Fujita en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EchigoTomoo en-aut-sei=Echigo en-aut-mei=Tomoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Regional Innovation, Hirosaki University kn-affil= affil-num=2 en-affil=Earthquake Research Institute, University of Tokyo kn-affil= affil-num=3 en-affil=Faculty of Education, Shinshu University kn-affil= affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=5 en-affil=Tono Geoscience center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Kankyo Chisitsu, Co. kn-affil= en-keyword=Marine terrace kn-keyword=Marine terrace en-keyword=Exposure age kn-keyword=Exposure age en-keyword=10Be kn-keyword=10Be en-keyword=Coastal uplift kn-keyword=Coastal uplift 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=11 cd-vols= no-issue= article-no= start-page=100998 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=Robustness of the RGB image-based estimation for rice above-ground biomass by utilizing the dataset collected across multiple locations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Above-ground biomass (AGB) is a critical phenotype representing crop growth. Non-invasive evaluations of AGB, including deep-learning-based red-green-blue (RGB) image analyses, are often specific to the training data. The robustness of the estimation model across untrained conditions is essential to monitor crop productivity globally, but it has yet to be fully assessed. This study aims to assess the robustness of a convolutional neural network (CNN) model for rice AGB estimation across five locations in three countries, and to demonstrate the feasibility of robust model via a practical approach. From transplanting to heading, 1957 RGB images were captured vertically downward over the rice canopy, covering approximately 1 m2. First, a base model was established using data collected from a single location. Then, its robustness was assessed using test datasets taken from the other four locations. The CNN model showed a significant variation in estimation accuracy across the untrained four locations, indicating insufficient robustness of the base model. Subsequently, we quantitatively tested the impact of improving training data diversity on model robustness by adding data from each of the four locations to the base model's training data. Adding at most 48 data points from a location achieved practical accuracy for the added location, with R2Ad above 0.8. Interestingly, adding data from one location sometimes improved the accuracy for other untrained locations as well. These findings suggest that collecting diverse training data for RGB-based estimation, combined with evaluation of robustness paves the way for on-site and instant AGB monitoring of rice. en-copyright= kn-copyright= en-aut-name=NakajimaKota en-aut-sei=Nakajima en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoKazuki en-aut-sei=Saito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujimotoYasuhiro en-aut-sei=Tsujimoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaiToshiyuki en-aut-sei=Takai en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MochizukiAtsushi en-aut-sei=Mochizuki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaguchiTomoaki en-aut-sei=Yamaguchi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbrahimAli en-aut-sei=Ibrahim en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MairouaSalifou Goube en-aut-sei=Mairoua en-aut-mei=Salifou Goube kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AndrianaryBruce Haja en-aut-sei=Andrianary en-aut-mei=Bruce Haja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatsuraKeisuke en-aut-sei=Katsura en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TanakaYu en-aut-sei=Tanaka en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=International Rice Research Institute (IRRI) kn-affil= affil-num=3 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=4 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=5 en-affil=CHIBA Prefectural Agriculture and Forestry Research Center kn-affil= affil-num=6 en-affil=Faculty of Applied Biological Sciences, Gifu University kn-affil= affil-num=7 en-affil= Africa Rice Center (AfricaRice), Regional Station for the Sahel kn-affil= affil-num=8 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=9 en-affil=Laboratoire des Radioisotopes, Universit? d′Antananarivo kn-affil= affil-num=10 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=11 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Robustness kn-keyword=Robustness en-keyword=RGB image kn-keyword=RGB image en-keyword=Rice, Above-ground biomass kn-keyword=Rice, Above-ground biomass en-keyword=Convolutional neural network kn-keyword=Convolutional neural network END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=405 end-page=412 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-World Outcomes of Anti-Vascular Endothelial Growth Factor Therapy for Neovascular Age-Related Macular Degeneration in Patients Aged 85 or Older en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the treatment outcomes of patients aged ?85 years with neovascular age-related macular degeneration (nAMD) who received anti-vascular endothelial growth factor (anti-VEGF) therapy using either treat-and-extend (TAE) or pro re nata (PRN) regimens for 1 year in real-world clinical practice. Eighty-five eyes from 85 patients were included. Among them, types 1, 2, and 3 macular neovascularization and polypoidal choroidal vasculopathy were present in 27.1%, 17.6%, 18.8%, and 36.5%, respectively. TAE and PRN regimens were used in 43.5% and 56.5% of patients, respectively. At baseline, the PRN group was older and had worse best-corrected visual acuity (BCVA), greater central retinal thickness, and more intraretinal fluid than the TAE group. In the TAE group, the mean number of injections was 7.6, BCVA improved significantly, and all retinal fluid rates decreased. In the PRN group, the mean number of injections was 3.9, BCVA remained unchanged, and the rates of macular fibrosis and atrophy increased. No serious adverse events were observed in either group. Anti-VEGF therapy was safe for patients aged ? 85 years with nAMD, and the TAE regimen effectively improved BCVA in this population. BCVA remained unchanged in the PRN-treated patients, with baseline disease severity and/or undertreatment potentially influencing the outcomes. en-copyright= kn-copyright= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Morizane HosokawaMio en-aut-sei=Morizane Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anti-vascular endothelial growth factor therapy kn-keyword=anti-vascular endothelial growth factor therapy en-keyword=neovascular age-related macular degeneration kn-keyword=neovascular age-related macular degeneration en-keyword=age kn-keyword=age en-keyword=treat-and-extend kn-keyword=treat-and-extend en-keyword=pro re nata kn-keyword=pro re nata END start-ver=1.4 cd-journal=joma no-vol=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=5 cd-vols= no-issue=2 article-no= start-page=101482 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=Amelioration of Cd-induced bone deterioration by orally administered calcium phosphate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cadmium (Cd) is a heavy metal that accumulates in the body, primarily through daily grain intake, and has a high affinity for bone, leading to skeletal diseases such as osteomalacia and fractures. Hydroxyapatite (HAp), a major bone mineral component, is highly pH-sensitive and is known to incorporate Cd, as observed in studies of Itai-itai disease. Based on these findings, we hypothesized that HAp could serve as an effective oral detoxification material for heavy metals. This study investigated the efficacy of orally administered HAp in inhibiting Cd-induced changes in bone physical and chemical properties, comparing its effects to those of activated charcoal (AC), a common detoxifying agent. Six-week-old male ICR mice were exposed to cadmium via drinking water containing CdCl2 and subsequently given diets containing either HAp or AC for four weeks. Three-point bending tests, micro-CT analysis, and histological observations of the femurs demonstrated that mice receiving HAp exhibited improved mechanical strength and enhanced bone quality protection compared to the control and other Cd-treated groups. Activated charcoal also contributed to bone quality improvement at low concentrations, but its effect diminished at high concentrations. These results suggest that the oral administration of HAp may be a promising therapeutic strategy for suppressing cadmium-induced osteomalacia. en-copyright= kn-copyright= en-aut-name=SungPing-chin en-aut-sei=Sung en-aut-mei=Ping-chin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BikharudinAhmad en-aut-sei=Bikharudin en-aut-mei=Ahmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MusaRanda en-aut-sei=Musa en-aut-mei=Randa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UchidaKenta en-aut-sei=Uchida en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtakaAkihisa en-aut-sei=Otaka en-aut-mei=Akihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsusakaTadaaki en-aut-sei=Matsusaka en-aut-mei=Tadaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsugakiAira en-aut-sei=Matsugaki en-aut-mei=Aira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoTakayoshi en-aut-sei=Nakano en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=8 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=9 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=10 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cadmium kn-keyword=Cadmium en-keyword=Bone deterioration kn-keyword=Bone deterioration en-keyword=Calcium phosphate kn-keyword=Calcium phosphate en-keyword=Bone quality kn-keyword=Bone quality END start-ver=1.4 cd-journal=joma no-vol=2025 cd-vols= no-issue=12 article-no= start-page=rjaf972 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic surgery for distal femoral physeal bar resection with computed tomography-assisted navigation: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=The formation of physeal bars, or bony bridges, following growth plate injuries can cause complications such as angular deformities or discrepancies in leg length. The management strategies for these depend on factors such as the bar’s location, extent, and residual growth potential. Herein, we describe the case of a 14-year-old male with a valgus knee deformity caused by a distal femoral physeal bar. The patient underwent endoscopic resection of the bar, assisted by computed tomography-based navigation and intraoperative O-arm imaging. This minimally invasive technique facilitated safe and accurate removal of the lesion with less risk of complications such as cortical perforation or injury to adjacent neurovascular structures compared to traditional approaches. The patient experienced favorable postoperative outcomes, including restored knee range of motion and full symptom resolution. This approach demonstrates the clinical value of integrating endoscopy with advanced navigation systems during the surgical treatment of physeal bars. en-copyright= kn-copyright= en-aut-name=MasadaYasutaka en-aut-sei=Masada en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoTetsuya en-aut-sei=Yamamoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoShin en-aut-sei=Matsumoto en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medical Materials for Musculoskeletal Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Advanced Rehabilitation Medicine for the Musculoskeletal System, Okayama University kn-affil= affil-num=10 en-affil=Center for Education in Medicine and Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=physeal bar kn-keyword=physeal bar en-keyword=computed tomography kn-keyword=computed tomography en-keyword=navigation kn-keyword=navigation END start-ver=1.4 cd-journal=joma no-vol=177 cd-vols= no-issue=4 article-no= start-page=e70398 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative Transcriptome Reveals ART1-Dependent Regulatory Pathways for Fe Toxicity Response in Rice Roots en-subtitle= kn-subtitle= en-abstract= kn-abstract=Iron (Fe) is an essential element for plants, but an excess supply can have detrimental effects. Fe toxicity induces complex physiological and genetic responses, and due to this complexity, the knowledge of transcriptional regulatory mechanisms under Fe toxicity is very limited. Previous studies suggested that plant responses to excess Fe involve oxidative stress caused by reactive oxygen species (ROS), which itself causes transcriptional changes. We hypothesized that dissecting these complex responses could lead to the identification of a novel factor and conducted a comparative transcriptome analysis using roots of rice plants exposed to nutrient solutions containing 1 or 5?mM of hydrogen peroxide (a major form of ROS) or 300?mg?L?1 of Fe (as FeSO4). Genes induced by hydrogen peroxide overlapped with 62%, 49%, and 30% of Fe toxicity-upregulated genes at 3?h, 1?day, and 3?days following treatment initiation. Subsequent gene co-expression analyses classified genes into 21 groups with varying responsiveness to ROS and Fe toxicity. Genes in group 15 were specifically upregulated by Fe toxicity and overlapped significantly with aluminum (Al)-inducible genes and target genes of the Zn-finger transcription factor, ART1, which regulates Al response in rice roots. Additional experiments using the art1 knock-out mutant demonstrated that ART1 is crucial for upregulating genes such as STAR2 and FRDL4 in response to Fe toxicity. This study reveals the contribution of ART1-dependent regulatory pathways in rice roots under Fe toxicity. en-copyright= kn-copyright= en-aut-name=UedaYoshiaki en-aut-sei=Ueda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WissuwaMatthias en-aut-sei=Wissuwa en-aut-mei=Matthias kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Crop, Livestock and Environment Division, Japan International Research Center for Agricultural Sciences kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Crop, Livestock and Environment Division, Japan International Research Center for Agricultural Sciences kn-affil= en-keyword=ART1 kn-keyword=ART1 en-keyword=gene co-expression analysis kn-keyword=gene co-expression analysis en-keyword=iron toxicity kn-keyword=iron toxicity en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=rice kn-keyword=rice END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=14 article-no= start-page=12551 end-page=12562 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250709 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mesoporous Oxyhalide Aggregates Exhibiting Improved Photocatalytic Activity for Visible-Light H2 Evolution and CO2 Reduction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oxyhalides are promising visible-light photocatalysts for water splitting and CO2 conversion; however, those exhibiting high activity for these reactions have rarely been reported. Here, we show that using water-soluble Ti complexes as precursors in the microwave-assisted hydrothermal synthesis of the oxyhalide photocatalyst Pb2Ti2O5.4F1.2 (PTOF) resulted in the production of nanoparticulate PTOF. The primary particle size of the synthesized PTOF ranged from several tens of nanometers to several hundreds of nanometers. Using Ti-citric acid or Ti-tartaric acid complexes as precursors, the PTOF was formed as mesoporous aggregates, compared with a bulky analogue (0.5?1 μm) prepared using a TiCl4 precursor. The PTOF prepared from Ti-citric acid complex had a particle size of 50?100 nm and showed a one-order-of-magnitude greater activity for H2 evolution from an aqueous ethylenediaminetetraacetic acid solution with the aid of a Rh cocatalyst. An apparent quantum yield (AQY) of 15.4 ± 1.0% at 420 nm, which is the highest among the reported oxyhalide photocatalysts, was achieved under optimal conditions. Although excess particle size reduction of PTOF lowered the H2 evolution activity, the PTOF with the smallest possible primary particle size of 15?30 nm, prepared from Ti-tartaric acid complex, showed the highest activity toward the selective reduction of CO2 into formate in a nonaqueous environment when combined with a binuclear Ru(II) complex. The CO2 reduction AQY was 10.4 ± 1.8% at 420 nm, a record-high value among metal-complex/semiconductor binary hybrid photocatalysts. This study highlights the importance of morphological control of oxyhalides for realizing their full potential as photocatalysts for artificial photosynthesis. en-copyright= kn-copyright= en-aut-name=UekiHiroto en-aut-sei=Ueki en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaToshiya en-aut-sei=Tanaka en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnabukiShuji en-aut-sei=Anabuki en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakadaRyuichi en-aut-sei=Nakada en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiMegumi en-aut-sei=Okazaki en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AiharaKenta en-aut-sei=Aihara en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HattoriMasashi en-aut-sei=Hattori en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiwariFumitaka en-aut-sei=Ishiwari en-aut-mei=Fumitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HarukiRie en-aut-sei=Haruki en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NozawaShunsuke en-aut-sei=Nozawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YokoiToshiyuki en-aut-sei=Yokoi en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaraMichikazu en-aut-sei=Hara en-aut-mei=Michikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IshitaniOsamu en-aut-sei=Ishitani en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SaekiAkinori en-aut-sei=Saeki en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= en-aut-name=MaedaKazuhiko en-aut-sei=Maeda en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=2 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=5 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=6 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Materials and Structures Laboratory, Institute of Integrated Research, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka University kn-affil= affil-num=9 en-affil=Institute of Materials Structure Science, High Energy Accelerator Research Organization kn-affil= affil-num=10 en-affil=Institute of Materials Structure Science, High Energy Accelerator Research Organization kn-affil= affil-num=11 en-affil=Nanospace Catalysis Unit, Institute of Integrated Research, Institute of Science Tokyo kn-affil= affil-num=12 en-affil=Materials and Structures Laboratory, Institute of Integrated Research, Institute of Science Tokyo kn-affil= affil-num=13 en-affil=Department of Chemistry, Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=14 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka University kn-affil= affil-num=15 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=16 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= en-keyword=artificial photosynthesis kn-keyword=artificial photosynthesis en-keyword=solar fuels kn-keyword=solar fuels en-keyword=mixed-anion compounds kn-keyword=mixed-anion compounds en-keyword=oxyfluorides kn-keyword=oxyfluorides en-keyword=water splitting kn-keyword=water splitting END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=1773 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Single-cell and spatial transcriptomic characterization of pulmonary pleomorphic carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulmonary pleomorphic carcinoma (PPC) is a rare subtype of lung cancer that comprises both epithelial and sarcomatoid components. The molecular basis of PPC, including the cellular dynamics of its components, remains largely unknown. To elucidate potential therapeutic targets for PPC, we perform a multi-omics analysis incorporating digital spatial profiling and single-cell RNA sequencing (scRNA-seq). PPC exhibits diverse driver gene alterations, including MET exon 14 skipping mutation (METex14) and ALK fusion. In spatial transcriptomics, MET gene and protein are overexpressed exclusively within the epithelial component and not in the sarcomatoid component, even in patients harboring METex14. Epithelial-mesenchymal transition (EMT)-related transcriptional changes, along with extracellular matrix (ECM) remodeling between the epithelial and sarcomatoid components, are observed. scRNA-seq identifies cell populations within the epithelial component that contribute to the malignant transformation and differentiation of the sarcomatoid component. They are characterized by an intermediate EMT state with ECM remodeling signature, suggesting their potential as novel therapeutic targets for PPC. en-copyright= kn-copyright=

vapor pressure en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates nitrogen distribution and isotope fractionation within synthetic 2:1 phyllosilicates, simulating submarine hydrothermal environments at 200 °C and saturated vapor pressure. XRD and EDS results revealed the potential coexistence of multiple cations in the interlayer of synthetic 2:1 phyllosilicate, concurrently suggesting cation substitution in the tetrahedral and/or octahedral sheets. Meanwhile, the iron-enriched 25-5 sample exhibited restricted interlayer expansibility. NH4+ absorptions were identified in the NH4-stretching (3200?2800 cm?1) and NH4-bending (1450?1400 cm?1) regions, with wavenumber shifts indicating the influence of interlayer water removal. At pH 10.56, over 95% of nitrogen was released into the gas phase, while at pH 8.88, nitrogen proportions in the liquid and gas phases were comparable (average 48?49%). Experiments with iron at pH ?8.80 showed that the nitrogen proportion in the gas phase (average 28%) was more than twofold lower than that in the liquid phase (average 68%). Equilibrium isotope fractionation factors indicated discernible preference for heavier nitrogen isotopes in the solid phase (αsolid-liquid = 1.009?1.021 and αsolid-gas = 1.011?1.027). The αliquid-gas range for sample 25?2 was 1.001?1.008, while that for the iron-enriched composite 25?5 was 0.997?1.010. Our experimental studies have confirmed that, in the absence of exchange interactions with external substances possessing different nitrogen isotope ratios, nitrogen isotope fractionation between ammonium and ammonia, controlled by variations in temperature and pH during mineralization, plays a crucial role in the variation of nitrogen isotope ratios. Additionally, we confirmed that metal-amines influence nitrogen isotope fractionation by modulating ammonia gas emission. These findings enhance our understanding of nitrogen cycling across the gas, liquid, and solid phases in submarine hydrothermal systems. en-copyright= kn-copyright= en-aut-name=JoJaeguk en-aut-sei=Jo en-aut-mei=Jaeguk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaToshiro en-aut-sei=Yamanaka en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiYouko en-aut-sei=Miyoshi en-aut-mei=Youko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiMasaya en-aut-sei=Suzuki en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuwaharaYoshihiro en-aut-sei=Kuwahara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChibaHitoshi en-aut-sei=Chiba en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LeeBum Han en-aut-sei=Lee en-aut-mei=Bum Han kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=5 en-affil=Department of Environmental Changes, Faculty of Social and Cultural Studies, Kyushu University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Critical Minerals Research Center, Korea Institute of Geoscience & Mineral Resources (KIGAM) kn-affil= en-keyword=Synthetic 2:1 phyllosilicates kn-keyword=Synthetic 2:1 phyllosilicates en-keyword=Nitrogen distribution kn-keyword=Nitrogen distribution en-keyword=Nitrogen isotope fractionation kn-keyword=Nitrogen isotope fractionation en-keyword=Hydrothermal system kn-keyword=Hydrothermal system END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=13 article-no= start-page=e202419624 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Conduction Band and Defect Engineering for the Prominent Visible‐Light Responsive Photocatalysts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Controlling trap depth is crucial to improve photocatalytic activity, but designing such crystal structures has been challenging. In this study, we discovered that in 2D materials like BiOCl and Bi4NbO8Cl, composed of interleaved [Bi2O2]2+ and Cl- slabs, the trap depth can be controlled by manipulating the slab stacking structure. In BiOCl, oxygen vacancies (VO) create deep electron traps, while chlorine vacancies (VCl) produce shallow traps. The depth is determined by the coordination around anion vacancies: VO forms strong σ bonds with Bi-6p dangling bonds below the conduction band minimum (CBM), while those around Cl are parallel, forming weak π-bonding. The strong re-hybridization makes the trap depth deeper. In Bi4NbO8Cl, VCl also creates shallow traps, but VO does not produce deep traps although Bi-6p orbitals are also forming strong σ bonding. This difference is attributed to the difference of the energy level of CBM. In both cases, the CBM consists of Bi-6p orbitals extending into the Cl layers. However, these orbitals are isolated in BiOCl, but those in Bi4NbO8Cl are bonded with each other between neighboring [Bi2O2]2+ layers. This unique bonding-based CBM prevents the formation of deep electron traps, and significantly enhances H2 evolution activity by prolonging the lifetime of highly reactive free electrons. en-copyright= kn-copyright= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaTakafumi en-aut-sei=Ogawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaKanta en-aut-sei=Ogawa en-aut-mei=Kanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaMakoto en-aut-sei=Ogawa en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoDaichi en-aut-sei=Kato en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhongChengchao en-aut-sei=Zhong en-aut-mei=Chengchao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KuwabaraAkihide en-aut-sei=Kuwabara en-aut-mei=Akihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeRyu en-aut-sei=Abe en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KageyamaHiroshi en-aut-sei=Kageyama en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Nanostructures Research Laboratory, Japan Fine Ceramics Center kn-affil= affil-num=4 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=5 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=6 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=7 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Nanostructures Research Laboratory, Japan Fine Ceramics Center kn-affil= affil-num=9 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=10 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= en-keyword=photocatalysis kn-keyword=photocatalysis en-keyword=defects kn-keyword=defects en-keyword=charge trapping kn-keyword=charge trapping en-keyword=recombination kn-keyword=recombination en-keyword=time-resolved spectroscopy kn-keyword=time-resolved spectroscopy END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=8 article-no= start-page=954 end-page=963 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term functional and quality of life outcomes after cementless minimally invasive extendable endoprosthesis replacement in skeletally immature patients with bone sarcomas at the lower limb a Japanese Musculoskeletal Oncology Group (JMOG) study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims
Extendable endoprostheses are utilized to reconstruct segmental defects following resection of bone sarcomas in skeletally immature children. However, there remains a paucity of data regarding long-term functional and quality of life outcomes.
Methods
We conducted a retrospective, multicentre study and reviewed 45 children who underwent cementless minimally invasive extendable endoprosthetic replacement. Anatomical sites included the distal femur (n = 29), proximal femur (n = 4), proximal tibia (n = 11), and total femur (n = 1). The mean follow-up period was 12 years. The mean age at extendable endoprosthetic replacement was ten years (5 to 15). Most patients (96%, 43/45) had reached skeletal maturity at the final follow-up.
Results
The ten-year endoprosthetic failure-free survival rate was 60%. Of the 45 patients, 25 (56%) had 42 complications which were frequently related to structural failure (45%, 19/42), with extension mechanism jamming being the most common (n = 7, 17%). Excluding lengthening procedures, 20 patients (44%) underwent additional surgery with a mean of two surgeries per patient. The mean limb-length discrepancy at the final follow-up was 2.3 cm. Limb salvage was achieved in 44 (98%) patients. The mean Musculoskeletal Tumor Society (MSTS) scores, Toronto Extremity Salvage Score (TESS), and EuroQol five-dimension five-level questionnaire (EQ-5D-5L) were 78%, 92%, and 92% at the last follow-up, respectively. Multiple additional surgeries (? 2 times) for complications were associated with worse MSTS scores compared with those without multiple additional surgeries (p = 0.009). Moreover, limb-length discrepancy > 3 cm showed significantly worse MSTS scores compared with those ? 3 cm (p = 0.019).
Conclusion
Extendable endoprostheses were associated with a high complication rate and need for additional surgeries over time, especially for structural-related complications. Despite this, successful limb salvage with reasonable function/quality of life and small limb-length discrepancy were achievable in the long term. Patients’ function in the long term depended on the experience of postoperative complications and limb-length discrepancy. en-copyright= kn-copyright= en-aut-name=TsudaYusuke en-aut-sei=Tsuda en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaYoshihiro en-aut-sei=Nishida en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoAkio en-aut-sei=Sakamoto en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OguraKoichi en-aut-sei=Ogura en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SekitaTetsuya en-aut-sei=Sekita en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawanoHirotaka en-aut-sei=Kawano en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobayashiHiroshi en-aut-sei=Kobayashi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, The University of Tokyo Hospital kn-affil= affil-num=2 en-affil=Department of Rehabilitation, Nagoya University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Graduate School of Medicine, Kyoto University kn-affil= affil-num=4 en-affil=Department of Musculoskeletal Oncology and Rehabilitation, National Cancer Center Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Musculoskeletal Oncology and Rehabilitation, National Cancer Center Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Teikyo University School of Medicine kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, The University of Tokyo Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=1714 end-page=1722 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Osmotic pressure‐induced calcium response states en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osmotic pressure is essential for maintaining cellular homeostasis; however, the mechanisms by which cells sense and respond to acute osmotic stress remain incompletely understood. Here, we applied rapid osmotic pressure stimulation to cultured HEK293T cells and observed dynamic intracellular calcium responses. Acute hypotonic stimulation evoked calcium response patterns, whereas hypertonic and isotonic stress did not elicit similar effects. Mechanistically, these calcium signals originated from the endoplasmic reticulum via ryanodine receptor 2 and propagated to neighboring cells through Connexin 43-mediated gap junctions. These findings reveal a previously unrecognized role for calcium signaling in the acute cellular response to osmotic stress, providing new insights into the mechanisms of intercellular communication during osmotic adaptation. en-copyright= kn-copyright= en-aut-name=GaoZidan en-aut-sei=Gao en-aut-mei=Zidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuMasatoshi en-aut-sei=Morimatsu en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Okayama Japan kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Okayama Japan kn-affil= en-keyword=calcium wave kn-keyword=calcium wave en-keyword=Connexin 43 kn-keyword=Connexin 43 en-keyword=hypotonic pressure kn-keyword=hypotonic pressure en-keyword=osmotic pressure kn-keyword=osmotic pressure en-keyword=ryanodine receptor kn-keyword=ryanodine receptor END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=EUS-Guided Versus Percutaneous Transhepatic Drainage of Liver Abscesses: A Multicenter Endohepatology Study in Western Japan (EPIC-LA Study) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Percutaneous transhepatic liver abscess drainage (PTAD) and endoscopic ultrasound-guided liver abscess drainage (EUS-LAD) have several limitations. Recently, because of technical improvements in echoendoscope maneuvers, EUS-guided access for the right hepatic lobe has been reported. The aim of this multicenter, retrospective study was to compare clinical outcomes of PTAD and EUS-LAD including the right hepatic lobe in West Japan.
Method: This retrospective, multicenter study included consecutive patients with liver abscesses between January 2019 and November 2024. The primary outcome in this study was the clinical success rate compared between EUS-LAD and PTAD.
Results: During the study period, 1012 consecutive patients developed liver abscesses. Of them, 734 patients were excluded, 43 underwent EUS-LAD and 235 patients underwent PTAD. After propensity score-matched analysis, the clinical success rate was significantly higher in the EUS-LAD group (97.7%, 42/43) than in the PTAD group (79.1%, 34/43) (p?=?0.007). After a propensity score-matched analysis, 25 patients were included in each group. The clinical success rate was significantly higher in the EUS-LAD group (100%, 25/25) than in the PTAD group (84%, 21/25) (p?=?0.037). Adverse events were also significantly higher in the PTAD group (16%, 5/25) than in the EUS-LAD group (p?=?0.025). In addition, the median length of hospital stay was significantly shorter in the EUS-LAD group (15?days) than in the PTAD group (22?days) (p?=?0.005).
Conclusions: EUS-LAD using a metal stent might be one of the options, but further randomized, controlled trials are needed. en-copyright= kn-copyright= en-aut-name=OguraTakeshi en-aut-sei=Ogura

papillary mucinous neoplasm with mural nodules by contrast-enhanced endoscopic ultrasound using time?intensity curve analysis with a new support program: A multicenter retrospective study (with video) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/objectives: Preoperative diagnosis of the pathological grade of intraductal papillary mucinous neoplasms (IPMN) is challenging. This study aimed to evaluate the accuracy of contrast-enhanced endoscopic ultrasound (CE-EUS) using time?intensity curve (TIC) analysis with a newly developed support program to differentiate between low-grade dysplasia (LGD) and high-grade dysplasia (HGD)/invasive carcinoma (IC) in IPMN.
Methods: This study retrospectively analyzed 32 patients who underwent CE-EUS using the support program for TIC analysis and IPMN resection (LGD: 17, HGD/IC: 15) at two medical centers. The TIC parameters of mural nodules (MN) were compared between the LGD and HGD/IC groups, and the diagnostic accuracies of the TIC parameters were evaluated.
Results: The MN/pancreatic parenchyma contrast ratio was significantly higher in the HGD/IC group than in the LGD group (1.53 vs. 0.99; P < 0.0001), and the diagnostic abilities of the contrast ratio were as follows: sensitivity, 67 %; specificity, 100 %; and accuracy, 84 %. There were no differences in the echo intensity reduction rate of the MNs between the two groups (HGD/IC, 61.6 vs. 61.2, 0.99; P = 0.421), and the diagnostic abilities of the reduction rate were as follows: sensitivity, 93 %; specificity, 41 %; and accuracy, 66 %.
Conclusions: The contrast ratio calculated using TIC analysis with the support program is potentially useful for differentiating between IPMNs with LGD and those with HGD/IC. en-copyright=

Japan's 2024 Physician Working‐Hour Limits on Labor Conditions, Self‐Directed Professional Development, and Happiness Among Obstetrician‐Gynecologists en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: To examine the short-term impacts of Japan's newly implemented physician working-hour limits (April 2024) on working conditions, self-directed professional development (SDPD), defined as activities undertaken outside working hours to enhance one's professional skills, and work-related happiness among obstetrician-gynecologists (OB-GYNs).
Methods: An online survey was conducted between July 8 and July 31, 2024, targeting 867 Japan Society of Obstetrics and Gynecology members. Five hundred and fourteen full-time practitioners who had not changed workplaces around April 2024 and had no missing data were analyzed. Participants were stratified by regulation levels (A, B, C, discretionary labor system, those who don't know their own level), and their working hours, anticipated income, SDPD satisfaction, and happiness (0?10 scale) were assessed. We used multivariate linear regression to evaluate the influence of labor condition changes on happiness and explored interactions involving unpaid overtime, income changes, and SDPD satisfaction.
Results: Compared with level A (up to 960?h of overtime per year), participants at levels B and C (up to 1860?h of overtime per year) reported significantly lower happiness (p? Conclusions: The new working-hour limits had minimal impact on labor conditions in the short run. However, satisfaction with SDPD was positively associated with happiness, whereas anticipated decreases in income were correlated with lower happiness. en-copyright= kn-copyright=

visualization during helical CT examinations: importance of X-ray incident direction analysis and central internal dose estimation en-subtitle= kn-subtitle= en-abstract= kn-abstract=During computed tomography (CT) examination, radiation exposures should be appropriately managed taking into considering the effects of bowtie filter, the heel effect and over-beaming effect. Furthermore, the analysis of an X-ray incident direction is important. The purpose of this study is to develop a procedure to obtain two-dimensional (2D) internal dose distributions based on actual measurements of surface dose distribution and central internal dose data. Experiments were conducted using a clinical CT scanner and four cylindrical polyacetal resin (POM) phantoms having diameters of 15?30 cm. The entrance surface doses and the central internal dose were measured by placing the optically stimulated luminescence (OSL) dosimeters on the surface and inner part of the phantom, respectively, during helical CT scans. The X-ray incident direction at the slice containing the dosimeter was estimated based on the noise distribution analysis of the CT image. Then, circumferential surface dose distributions were determined as a function of the X-ray incident direction. Based on these experimental data, we succeeded in visualizing the 2D dose distributions. The obtained dose distribution was inhomogeneous, clearly reflecting the influence of factors such as the heel effect. The uncertainty due to our methodology was estimated to be from 4.3 % to 7.4 %. Our methodology needs central internal dose data, and the absence of this data introduced additional systematic uncertainties of +6.9 % to ?11.4 %. In conclusion, correcting for the effect of the X-ray incident directions for entrance surface dose and adding the central inner dose data can improve the reliability of the internal dose distribution. en-copyright= kn-copyright= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakegamiKazuki en-aut-sei=Takegami en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishigamiRina en-aut-sei=Nishigami en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiDaiki en-aut-sei=Kobayashi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotoSota en-aut-sei=Goto en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakemitsuMasaki en-aut-sei=Takemitsu en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshiiRin en-aut-sei=Ishii en-aut-mei=Rin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MorimotoShinichi en-aut-sei=Morimoto en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MakiMotochika en-aut-sei=Maki en-aut-mei=Motochika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Yamaguchi University Hospital kn-affil= affil-num=3 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=4 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=5 en-affil=Faculty of Health Sciences, Kobe Tokiwa University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Yamaguchi University Hospital kn-affil= affil-num=9 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=10 en-affil=Meditec Japan Co., Ltd. kn-affil= affil-num=11 en-affil=Meditec Japan Co., Ltd. kn-affil= en-keyword=Computed tomography kn-keyword=Computed tomography en-keyword=Medical dosimetry kn-keyword=Medical dosimetry en-keyword=Internal dose distribution kn-keyword=Internal dose distribution en-keyword=X-ray incident direction kn-keyword=X-ray incident direction en-keyword=Optically stimulated luminescence dosimeter kn-keyword=Optically stimulated luminescence dosimeter END start-ver=1.4 cd-journal=joma no-vol=191 cd-vols= no-issue= article-no= start-page=107592 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel wearable dosimeter system that can analyze the incident direction of X-rays for medical dosimetry ? Improvements to the detector arrangements and analysis algorithm ? en-subtitle= kn-subtitle= en-abstract= kn-abstract=When performing real-time dosimetry using an active-type dosimeter during clinical fluoroscopic procedures, angular dependence of dosimeter response should be taken into account. Our research group addressed this issue and proposed a triple-type dosimeter that can determine the incident angle of scattered X-rays. The triple-type detector consists of three active dosimeters. The two side dosimeters have slope filters to enhance the angular dependence and are intentionally tilted. The central dosimeter faces forward. The incident angle of X-rays (θin) is estimated using the signal differences between the central dosimeter and the left and/or right dosimeters. Then, the absolute dose is determined by correcting the angular dependence of the central dosimeter based on the estimated θin. In order to verify the concept of the triple-type dosimeter, we conducted a proof-of-concept experiment using clinical X-ray fluoroscopic equipment. Scattered X-rays were generated by irradiating an elliptical cylindrical water phantom. The response of the triple-type dosimeter was evaluated by rotating it to vary the incident angle of scattered X-rays generated by the water phantom. The proposed dosimetry system could estimate the θin over an angular range of ±80° (with uncertainty of 1.35°), which is 30° wider than the previous version, and successfully determined the absolute doses after correction for the angular dependence of the dosimeter. Although the active-type dosimeter had a systematic uncertainty related to the angular dependence of ±15.2 %, our system succeeded in reducing the systematic uncertainty to ±3.2 %. en-copyright= kn-copyright= en-aut-name=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishigamiRina en-aut-sei=Nishigami en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiDaiki en-aut-sei=Kobayashi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotoSota en-aut-sei=Goto en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakegamiKazuki en-aut-sei=Takegami en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshiiRin en-aut-sei=Ishii en-aut-mei=Rin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MitaniMana en-aut-sei=Mitani en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HondaMitsugi en-aut-sei=Honda en-aut-mei=Mitsugi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=3 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=4 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=5 en-affil=Faculty of Health Science, Kobe Tokiwa University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Yamaguchi University Hospital kn-affil= affil-num=7 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=8 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=9 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= en-keyword=Wearable active-type dosimeter kn-keyword=Wearable active-type dosimeter en-keyword=X-ray incident direction kn-keyword=X-ray incident direction en-keyword=Occupational dose kn-keyword=Occupational dose en-keyword=Interventional radiology kn-keyword=Interventional radiology END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=2 article-no= start-page=103274 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimization of the reconstruction kernel for temporal bone imaging using photon-counting detector CT: A combined physical and visual evaluation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Photon-counting detector CT (PCD-CT) offers superior spatial resolution and noise characteristics compared to conventional CT. However, optimal reconstruction parameters for temporal bone imaging, especially kernel selection, remain unclear. This study aimed to identify the optimal reconstruction kernel using both objective physical image quality metrics and subjective expert assessments.
Methods: In phantom experiments, the system performance function (SPF) based on the task-based transfer function (TTF) and noise power spectrum (NPS) was calculated across 11 reconstruction kernels (Hr60?Hr98). Based on the results of the physical evaluation and clinical considerations from clinical practice, a subset of kernels was selected for visual assessment. For clinical images, two diagnostic radiologists evaluated three fine anatomical structures (i.e., stapes footplate, incudomalleolar joint, and cochlea) and overall image quality using both a ranking method and a 5-point Likert scale.
Results: TTF analysis indicated that Hr96 had the highest spatial resolution, while Hr60 showed the lowest noise in the NPS. SPF analysis identified Hr72 as providing the optimal balance between resolution and noise. Visual assessment using four reconstruction kernels (Hr60, Hr72, Hr76, and Hr84) showed that Hr76 consistently received the highest preference for overall image quality and visualization of fine structures. Statistically significant differences were observed among the kernels, with Hr60 consistently rated the lowest (p < 0.05).
Conclusion: The kernel Hr76 was found suitable for middle and inner ear diagnoses using PCD-CT, providing a good balance between spatial resolution and image noise. This finding provides a foundation for standardized reconstruction protocols in high-resolution temporal bone imaging.
Implications for practice: These findings support the use of Hr76 as a standard kernel for high-resolution temporal bone imaging and may contribute to protocol optimization in clinical PCD-CT practice. en-copyright= kn-copyright= en-aut-name=NishiiS. en-aut-sei=Nishii en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsaharaT. en-aut-sei=Asahara en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimitsuY. en-aut-sei=Morimitsu en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KajisakiS. en-aut-sei=Kajisaki en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiN. en-aut-sei=Akagi en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HondaM. en-aut-sei=Honda en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayashiH. en-aut-sei=Hayashi en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugayaA. en-aut-sei=Sugaya en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MunetomoK. en-aut-sei=Munetomo en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HigakiF. en-aut-sei=Higaki en-aut-mei=F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HirakiT. en-aut-sei=Hiraki en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IguchiT. en-aut-sei=Iguchi en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= affil-num=8 en-affil=Department of Otolaryngology, Head & Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=10 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=11 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= en-keyword=Photon-counting CT kn-keyword=Photon-counting CT en-keyword=Temporal bone imaging kn-keyword=Temporal bone imaging en-keyword=Reconstruction kernel kn-keyword=Reconstruction kernel en-keyword=Image quality kn-keyword=Image quality END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=10 article-no= start-page=908 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Comparative Study of Authoring Performances Between In-Situ Mobile and Desktop Tools for Outdoor Location-Based Augmented Reality en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, Location-Based Augmented Reality (LAR) systems have been increasingly implemented in various applications for tourism, navigation, education, and entertainment. Unfortunately, the LAR content creation using conventional desktop-based authoring tools has become a bottleneck, as it requires time-consuming and skilled work. Previously, we proposed an in-situ mobile authoring tool as an efficient solution to this problem by offering direct authoring interactions in real-world environments using a smartphone. Currently, the evaluation through the comparison between the proposal and conventional ones is not sufficient to show superiority, particularly in terms of interaction, authoring performance, and cognitive workload, where our tool uses 6DoF device movement for spatial input, while desktop ones rely on mouse-pointing. In this paper, we present a comparative study of authoring performances between the tools across three authoring phases: (1) Point of Interest (POI) location acquisition, (2) AR object creation, and (3) AR object registration. For the conventional tool, we adopt Unity and ARCore SDK. As a real-world application, we target the LAR content creation for pedestrian landmark annotation across campus environments at Okayama University, Japan, and Brawijaya University, Indonesia, and identify task-level bottlenecks in both tools. In our experiments, we asked 20 participants aged 22 to 35 with different LAR development experiences to complete equivalent authoring tasks in an outdoor campus environment, creating various LAR contents. We measured task completion time, phase-wise contribution, and cognitive workload using NASA-TLX. The results show that our tool made faster creations with 60% lower cognitive loads, where the desktop tool required higher mental efforts with manual data input and object verifications. en-copyright= kn-copyright= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Sandi KyawHtoo Htoo en-aut-sei=Sandi Kyaw en-aut-mei=Htoo Htoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RiyantokoPrismahardi Aji en-aut-sei=Riyantoko en-aut-mei=Prismahardi Aji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=location-based augmented reality (LAR) kn-keyword=location-based augmented reality (LAR) en-keyword=in-situ authoring kn-keyword=in-situ authoring en-keyword=authoring workflow kn-keyword=authoring workflow en-keyword=cognitive workload kn-keyword=cognitive workload en-keyword=NASA-TLX kn-keyword=NASA-TLX END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e00463-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of the drug target of the anti-tuberculosis compound OCT313: phosphotransacetylase is a potential drug target for anti-mycobacterial agents en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tuberculosis (TB) is one of the most common infectious diseases caused by bacteria worldwide. The increasing prevalence of multidrug-resistant TB (MDR-TB) and latent TB infection (LTBI) has intensified the global TB burden. Therefore, the development of new drugs for MDR-TB and LTBI is urgently required. We have reported that the derivative of dithiocarbamate sugar derivative, 2-acetamido-2-deoxy-β-D-glucopyranosyl N,N-dimethyldithiocarbamate (OCT313), exhibits anti-mycobacterial activity against MDR-MTB. Here, we identified the target of OCT313. In experimentally generated OCT313-resistant bacteria, adenine at position 1,092 in the metabolic enzyme phosphotransacetylase (PTA) gene was replaced with cytosine. This mutation is a nonsynonymous mutation that converts methionine to leucine at position 365 in the PTA protein. OCT313 inhibited the enzymatic activity of recombinant wild-type PTA, but not of the mutant PTA (M365L). PTA is an enzyme that produces acetyl-coenzyme A (acetyl-CoA) from acetyl phosphate and CoA and is involved in metabolic pathways; therefore, it was expected to also be active against dormant Mycobacterium tuberculosis bacilli. OCT313 exhibits antibacterial activity in the Wayne model of dormancy using Mycobacterium bovis BCG, and overexpression of PTA in OCT313-resistant bacilli restored sensitivity to OCT313. Collectively, the target of OCT313 is PTA, and OCT313 is a promising antimicrobial candidate for MDR-TB and LTBI. en-copyright= kn-copyright= en-aut-name=TakiiTakemasa en-aut-sei=Takii en-aut-mei=Takemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaTomohiro en-aut-sei=Hasegawa en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItohSaotomo en-aut-sei=Itoh en-aut-mei=Saotomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaShinji en-aut-sei=Maeda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaTakayuki en-aut-sei=Wada en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoritaYasuhiro en-aut-sei=Horita en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiyamaAkihito en-aut-sei=Nishiyama en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoSohkichi en-aut-sei=Matsumoto en-aut-mei=Sohkichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KimishimaAoi en-aut-sei=Kimishima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AsamiYukihiro en-aut-sei=Asami en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HidaShigeaki en-aut-sei=Hida en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OnozakiKikuo en-aut-sei=Onozaki en-aut-mei=Kikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Mycobacterium Reference and Research, the Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=2 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=3 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=4 en-affil=Graduate School of Pharmaceutical Sciences, Hokkaido University of Sciences kn-affil= affil-num=5 en-affil=Department of Microbiology, Graduate School of Human Life and Ecology, Osaka Metropolitan University kn-affil= affil-num=6 en-affil=Department of Clinical Pharmaceutics, Graduate School of Medical Sciences, Nagoya City University kn-affil= affil-num=7 en-affil=Department of Bacteriology, Niigata University School of Medicine kn-affil= affil-num=8 en-affil=Department of Bacteriology, Niigata University School of Medicine kn-affil= affil-num=9 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Laboratory of Applied Microbial Chemistry, ?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=11 en-affil=Laboratory of Applied Microbial Chemistry, ?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=12 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=13 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= en-keyword=phosphotransacetylase kn-keyword=phosphotransacetylase en-keyword=acetyl coenzyme A kn-keyword=acetyl coenzyme A en-keyword=dithiocarbamate kn-keyword=dithiocarbamate en-keyword=N-acetyl glucosamine kn-keyword=N-acetyl glucosamine en-keyword=anti-mycobacterial agents kn-keyword=anti-mycobacterial agents en-keyword=latent tuberculosis infection kn-keyword=latent tuberculosis infection END start-ver=1.4 cd-journal=joma no-vol=1873 cd-vols= no-issue=2 article-no= start-page=120091 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SPRED2 controls the severity of cisplatin-induced acute kidney injury by inhibiting ERK activation and TNFα production in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cisplatin is an effective chemotherapeutic agent used to treat solid tumors, but its clinical use is limited by acute kidney injury (AKI), in which ERK signaling plays a crucial role. Here, we investigated whether Sprouty-related EVH1 domain-containing protein 2 (SPRED2), an endogenous inhibitor of the Ras/Raf/ERK pathway, protects against cisplatin-induced AKI. Spred2?/? mice showed more severe renal injury and stronger ERK activation than wild-type (WT) mice, whereas pretreatment with the MEK inhibitor U0126 markedly attenuated the injury. In HK-2 cells (proximal tubular cells), SPRED2 knockdown enhanced cisplatin-induced apoptosis and caspase-3 activation, accompanied by decreased Bcl-2 expression. Spred2?/? kidneys displayed increased macrophage infiltration and elevated Tnfα, Il1b, and Ccl2 expression. Neutralization of TNFα with anti-TNFα antibody ameliorated renal injury and reduced the levels of Il1b and Ccl2 mRNA in Spred2?/? mice. In vitro, TNFα slightly decreased the viability of control and SPRED2 knockdown HK-2 cells without cisplatin treatment, but the decreased viability was augmented in SPRED2 knockdown cells by cisplatin. Immunohistochemistry revealed that macrophages were the predominant TNFα-positive cell population. Bone marrow?derived macrophages from Spred2?/? mice produced higher levels of TNFα in response to cisplatin compared with control cells, and this increase was markedly suppressed by U0126.
These findings indicate that endogenous SPRED2 protects kidneys from cisplatin-induced AKI by limiting ERK activation, tubular apoptosis, and TNFα-mediated inflammation. en-copyright= kn-copyright= en-aut-name=YangXu en-aut-sei=Yang en-aut-mei=Xu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HeJiali en-aut-sei=He en-aut-mei=Jiali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KunkelSteven L. en-aut-sei=Kunkel en-aut-mei=Steven L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology, University of Michigan Medical School kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cisplatin kn-keyword=Cisplatin en-keyword=ERK kn-keyword=ERK en-keyword=Macrophage kn-keyword=Macrophage en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=TNFα kn-keyword=TNFα END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=2 article-no= start-page=26-1566 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=放射線治療装置の回転座標系誤差が軸外targetの照射精度に及ぼす影響とTG142のトレランスの評価 en-subtitle= kn-subtitle= en-abstract=Purpose: The aim of this study was to quantitatively evaluate the impact of gantry, collimator, and couch rotational errors in a linear accelerator on the irradiation accuracy of off-isocenter targets, and to assess the validity of the rotational error tolerance (±1.0°) specified in American Association of Physicists in Medicine TG142. Methods: Using an Elekta linear accelerator (Elekta, Stockholm, Sweden) and the MultiMet-WL QA phantom (Sun Nuclear, Melbourne, FL, USA), an off-isocenter Winston?Lutz test was performed on six targets. In addition to baseline measurements, six conditions were evaluated by intentionally introducing rotational errors of +0.5° and +1.0° in the collimator, gantry, and couch. The vector distance (S value) between the field center and the target center, as well as positional deviations in each direction (gantry-target: GT, left-right: LR, anterior-posterior: AP), were analyzed. Results: Targets located farther from the isocenter exhibited more significant positional deviations. The collimator rotation had the greatest impact; at 7 cm from the isocenter, even a 0.5° error resulted in a maximum S value of 1.24 mm. Couch rotation had the next largest effect, while gantry rotation had relatively smaller effects, likely because most targets were located near the gantry’s rotational axis. The rotational errors mainly caused geometric deviations with direction-dependent positional shifts. Conclusion: The effects of the collimator and couch were substantial, with positional deviations exceeding 1 mm even for a 0.5° rotation error. The influence of the gantry was relatively small and dependent on the target configuration. For irradiation of off-axis targets, the TG142 tolerance of ±1.0° should be regarded as a minimum standard that must be strictly observed regardless of the type of linear accelerator. However, depending on the target arrangement, clinically adequate margins may not be ensured. These findings suggest the necessity of applying stricter criteria according to target configuration and emphasize the importance of regular quality assurance. kn-abstract=【目的】放射線治療装置の回転座標系の誤差が軸外targetの照射精度に及ぼす影響を定量的に評価し,TG142における回転座標系誤差(±1.0°)のトレランスの妥当性を検討する.【方法】Elekta社製放射線治療装置(Elekta, Stockholm, Sweden)とMultiMet-WL QAファントム(Sun Nuclear, Melbourne, FL, USA)を用いて,6個のtargetに対してoff isocenterのWinston?Lutz test(WL test)を実施した.Baselineの測定に加え,意図的にcollimator,gantry,couchに+0.5°, +1.0°回転誤差を加えた6条件で測定を行い,照射野中心とtarget中心のベクトル距離(S値)および各方向(gantry-target: GT, left-right: LR, anterior-posterior: AP)の位置ずれを解析した.【結果】Isocenterからの距離が大きいtargetほど位置ずれが顕著であった.特にcollimator回転誤差の影響が最も大きく,isocenterから7?cm離れたtargetでは0.5°の回転誤差でもS値が最大1.24?mmに達した.次に影響が大きかったのはcouch回転であり,gantry回転はtargetの配置が回転軸に近いものが多く相対的に影響が少なかった.回転座標系の誤差は幾何学的誤差の影響が強く,位置ずれに方向依存性があった.【結語】Collimatorやcouchの影響が大きく,0.5°の誤差でも1?mm以上の位置ずれが生じることがあった.Gantryの影響はtargetの配置依存があり,相対的に小さかった.軸外targetの照射において,TG142の±1.0°のトレランスは放射線治療装置の種類にかかわらず最低限遵守するべき基準であり,targetの配置次第では臨床的に十分なマージンを保証できない可能性が示された.Target配置に応じたより厳格な基準と定期的quality assurance(QA)の重要性が示唆された. en-copyright= kn-copyright= en-aut-name=NakayamaTakahiro en-aut-sei=Nakayama en-aut-mei=Takahiro kn-aut-name=中山貴裕 kn-aut-sei=中山 kn-aut-mei=貴裕 aut-affil-num=1 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name=田辺悦章 kn-aut-sei=田辺 kn-aut-mei=悦章 aut-affil-num=2 ORCID= en-aut-name=FujiiYasushi en-aut-sei=Fujii en-aut-mei=Yasushi kn-aut-name=藤井康志 kn-aut-sei=藤井 kn-aut-mei=康志 aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Radiology, Public Mutual Aid Association Chugoku Central Hospital kn-affil=公立学校共済組合中国中央病院放射線科 affil-num=2 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil=岡山大学学術研究院保健学域放射線技術科学専攻 affil-num=3 en-affil=Department of Radiology, Public Mutual Aid Association Chugoku Central Hospital kn-affil=公立学校共済組合中国中央病院放射線科 en-keyword=off-isocenter Winston?Lutz test kn-keyword=off-isocenter Winston?Lutz test en-keyword=rotation error kn-keyword=rotation error en-keyword=off-axis targets kn-keyword=off-axis targets en-keyword=Elekta kn-keyword=Elekta en-keyword=TG142 kn-keyword=TG142 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e85955 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250613 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Outcomes and Biomechanical Evaluation of the Cement-Catching Screw Technique for Osteoporotic Vertebral Fractures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: We developed a cement-catching screw (CCS) technique for pedicle screw insertion into hardened cement, connecting anterior and posterior vertebral elements during balloon kyphoplasty (BKP) for osteoporotic vertebral fractures (OVFs). This study reports the CCS technique, clinical outcomes, and biomechanical properties.
Methods: This retrospective study included 59 patients (20 men, 39 women; mean age, 77.4 ± 8.7 years) who underwent BKP with one-above-one-below posterior fixation for OVFs between 2020 and 2023. Patients were divided into CCS (?) (without intermediate screws, n = 28) and CCS (+) (with intermediate CCSs, n = 31) groups. Clinical and radiographic outcomes, including activities of daily living, vertebral wedge angle (VWA), surgical level Cobb angle (CA), anterior vertebral body height (AVBH), screw loosening, pullout, and adjacent vertebral fractures, were evaluated preoperatively, postoperatively, and at the final follow-up (?6 months). Biomechanical pullout strength was assessed at different insertion depths (5, 10, and 15 mm) using polymethylmethacrylate cement.
Results: No significant differences were observed between groups in age, sex, follow-up duration, or blood loss; however, the operation time was significantly longer in the CCS (+) group than in the CCS (?) group (P < 0.0001). Radiographic outcomes showed no significant differences in the VWA, CA, AVBH, adjacent vertebral fracture rates, and reoperation rates. However, the incidence of adjacent pedicle screws loosening and pullout was significantly higher in the CCS (?) group than in the CCS (+) group (P = 0.046 and 0.0084, respectively). The correction loss of the CA was significantly lower in the CCS (+) group (CCS (?), 5.6° ± 4.8°; CCS (+), 3.5° ± 4.8°, P = 0.023). The biomechanical test revealed pullout strengths of 683 ± 164, 2231 ± 208, and 3477 ± 393 N for insertion depths of 5, 10, and 15 mm, respectively, with significant increases by depth (P = 0.003 and 0.009).
Conclusions: The CCS technique improves anterior-posterior vertebral body stability, enhances fixation strength, and contributes to better surgical outcomes in OVFs treatment. en-copyright= kn-copyright= en-aut-name=ShitozawaHisakazu en-aut-sei=Shitozawa en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JokoRyoji en-aut-sei=Joko en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiMasaya en-aut-sei=Takahashi en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShiozakiYasuyuki en-aut-sei=Shiozaki en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UedaMasataka en-aut-sei=Ueda en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakatoriRyo en-aut-sei=Takatori en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YamashitaKazutaka en-aut-sei=Yamashita en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Ryusou Orthopaedic Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic surgery, Mitoyo General Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=balloon kyphoplasty kn-keyword=balloon kyphoplasty en-keyword=cement-catching screw kn-keyword=cement-catching screw en-keyword=intermediate screws kn-keyword=intermediate screws en-keyword=osteoporotic vertebral fractures kn-keyword=osteoporotic vertebral fractures en-keyword=pullout strength kn-keyword=pullout strength END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=e80656 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Charcot Spine Arthropathy at the Lumbosacral Level in a Patient With Ankylosis of the Spine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Charcot spinal arthropathy, a rare refractory progressive disease, is characterized by symptoms such as pain, deformity, and neurological impairment, which can significantly reduce functional ability, quality of life, and life expectancy. We report a case of Charcot spine at the L5/S1 level with long segment ankylosis to the L5 vertebra. We first performed thorough debridement via a posterior approach. We used antibiotic-containing cement as a spacer to fill the dead space, facilitating the second surgery approach. In the second surgery, transdiscal screws, which have a low profile and strong force, were used as anchors, and bulk bone harvested from both iliac bones was grafted to the intervertebral space. The lumbosacral alignment was kyphotic, and the patient could sit and move independently. Disimpaction was impossible, and a stoma had to be created. en-copyright= kn-copyright= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

Multi-Faceted Performance Comparison with a Scratch-Trained Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Developing high-performance artificial intelligence (AI) models for rare diseases like malignant bone tumors is limited by scarce annotated data. This study evaluates same-modality cross-domain transfer learning by comparing an AI model pretrained on chest radiographs with a model trained from scratch for detecting malignant bone tumors on knee radiographs. Methods: Two YOLOv5-based detectors differed only in initialization (transfer vs. scratch). Both were trained/validated on institutional data and tested on an independent external set of 743 radiographs (268 malignant, 475 normal). The primary outcome was AUC; prespecified operating points were high-sensitivity (?0.90), high-specificity (?0.90), and Youden-optimal. Secondary analyses included PR/F1, calibration (Brier, slope), and decision curve analysis (DCA). Results: AUC was similar (YOLO-TL 0.954 [95% CI 0.937?0.970] vs. YOLO-SC 0.961 [0.948?0.973]; DeLong p = 0.53). At the high-sensitivity point (both sensitivity = 0.903), YOLO-TL achieved higher specificity (0.903 vs. 0.867; McNemar p = 0.037) and PPV (0.840 vs. 0.793; bootstrap p = 0.030), reducing ~17 false positives among 475 negatives. At the high-specificity point (~0.902?0.903 for both), YOLO-TL showed higher sensitivity (0.798 vs. 0.764; p = 0.0077). At the Youden-optimal point, sensitivity favored YOLO-TL (0.914 vs. 0.892; p = 0.041) with a non-significant specificity difference. Conclusions: Transfer learning may not improve overall AUC but can enhance practical performance at clinically crucial thresholds. By maintaining high detection rates while reducing false positives, the transfer learning model offers superior clinical utility. Same-modality cross-domain transfer learning is an efficient strategy for developing robust AI systems for rare diseases, supporting tools more readily acceptable in real-world screening workflows.

Tomography-Based Navigation System for Total Hip Arthroplasty in Severe Hip Dysplasia: A Simulation Study Using 3D-Printed Bone Models of Crowe Types II, III, and IV en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objective: The use of computed tomography (CT)-based navigation systems has been shown to improve surgical accuracy in total hip arthroplasty. However, there is limited literature available about the application of CT-based navigation systems in severe hip dysplasia. This study aimed to evaluate the accuracy of a CT-based navigation system in patients with severe hip dysplasia using three-dimensional (3D)-printed bone models. Methods: 3D-printed bone models were generated from CT data of patients with severe hip dysplasia (Crowe type II, 10 hips; type III, 10 hips; and type IV, 10 hips). The accuracy of automatic segmentation, success rate, point-matching accuracy across different registration methods, and deviation values at reference points after registration were assessed. Results: For the combined cohort of Crowe II, III, and IV cases (n = 30), the Dice Similarity Coefficient and Jaccard Index were 0.99 ± 0.01 and 0.98 ± 0.02, respectively. These values indicate a high level of segmentation accuracy. The “Matching with true and false acetabulum + iliac crest” method achieved a 100% success rate across all groups, with mean deviations of 0.08 ± 0.28 mm in the Crowe II group, 0.12 ± 0.33 mm in the Crowe III group, and 0.14 ± 0.50 mm in the Crowe IV group (p = 0.572). In the Crowe IV group, the anterior superior iliac spine deviation was significantly lower using the “Matching with true and false acetabulum + iliac crest” method compared to the “Matching with true and false acetabulum” method (0.28 ± 0.49 mm vs. 3.29 ± 2.56 mm, p < 0.05). Conclusions: This study demonstrated the high accuracy of automatic AI-based segmentation, with a Dice Similarity Coefficient of 0.99 ± 0.01 and a Jaccard Index of 0.98 ± 0.02 in the combined cohort of Crowe type II, III, and IV cases (n = 30). The matching success rate was 100%, with additional points on the iliac crest, which improved matching accuracy and reduced deviations, depending on the case. en-copyright= kn-copyright= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KouraTakashi en-aut-sei=Koura en-aut-mei=Takashi 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=MasadaYasutaka en-aut-sei=Masada en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=CT-based navigation kn-keyword=CT-based navigation en-keyword=bone model kn-keyword=bone model en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=Ortoma Treatment Solution kn-keyword=Ortoma Treatment Solution END start-ver=1.4 cd-journal=joma no-vol=48 cd-vols= no-issue=9 article-no= start-page=2413 end-page=2426 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and safety of esaxerenone in hypertensive patients with chronic kidney disease, with or without type 2 diabetes mellitus: a pooled analysis of five clinical studies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective management of blood pressure (BP) and albuminuria are crucial for suppressing chronic kidney disease (CKD) progression and cardiovascular risks in hypertension. This pooled analysis evaluated the antihypertensive effects, organ-protective effects, and safety of esaxerenone in hypertensive patients with CKD by integrating five clinical studies of esaxerenone. Patients were divided based on type 2 diabetes mellitus (T2DM) status (with or without T2DM) and creatinine-based estimated glomerular filtration rate (eGFRcreat) (30 to <60 and ?60?mL/min/1.73 m2). Significant changes in morning home BP from baseline at Week 12 were observed in the overall population (mean change ?12.8/???5.4?mmHg), T2DM subgroups (???12.2/???4.5 and ?14.5/???7.8?mmHg), and eGFRcreat subgroups (???12.5/???4.7 and ?14.0/???6.9?mmHg) (all P? Materials and Methods: Individuals with obesity disease diagnosed according to the criteria of the Japan Society for the Study of Obesity were registered in J-ORBIT from seven medical centers in Japan. We analyzed the relationship between body mass index (BMI), clinical characteristics, and the prevalence of obesity-related health disorders in this cohort.
Results: Data were obtained from 1,169 individuals, with a mean (±SD) age of 56.9?±?15.3?years and a BMI of 31.4?±?6.1?kg/m2. The prevalence of health disorders varied substantially across BMI categories, with a higher BMI being associated with an increased prevalence of hyperuricemia or gout, obstructive sleep apnea syndrome or obesity hypoventilation syndrome, musculoskeletal disorders, and obesity-related kidney disease, as well as with a higher frequency of both a family history of obesity and of a history of childhood obesity. Among individuals with a BMI of ?25?kg/m2, the prevalence of hypertension and dyslipidemia did not increase with BMI, whereas that of glucose intolerance decreased with increasing BMI.
Conclusions: The J-ORBIT system, which collects clinical data in real time directly from EMRs, has the potential to provide insight into obesity and its associated health conditions, thereby contributing to improved care of affected individuals. en-copyright= kn-copyright= en-aut-name=NishikageSeiji en-aut-sei=Nishikage en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with end-stage renal disease have lower fasting plasma glucose and HbA1c levels, with significantly higher insulin levels. For a long time, it has been believed that this higher insulin level in renal failure is due to decreased insulin clearance caused by reduced renal function. However, here we reported that accumulation of the gut microbiota-derived uremic toxin, phenyl sulfate (PS) in the renal failure, increased insulin secretion from the pancreas by enhanced glucose-stimulated insulin secretion. Other endogenous sulfides compounds which accumulated as in the renal failure also increased glucose-stimulated insulin secretion from β?-cell. With RNA-seq analyses and gene knock down, we demonstrated that insulin secretion evoked by PS was mediated by Ddah2. In addition, we also found that PS increased insulin resistance through lncRNA expression and Erk phosphorylation in the adipocytes. To confirm the relationship between PS and glucose metabolism in human, we recruited 2 clinical cohort studies (DKD and CKD) including 462 patients, and found that there was a weak negative correlation between PS and HbA1c. Because these trials did not measure fasting insulin level, we alternatively used the urinary C-peptide/creatinine ratio (UCPCR) as an indicator of insulin resistance. We found that PS may induce insulin resistance in patients with eGFR? Methods: Fourteen MDA5-DM patients with multiple adverse prognostic factors were studied. Seven received the BRT-Tx regimen, and the remaining seven, previously treated with TC-Tx, served as historical controls. Twelve-month survival was assessed. Transcriptome analysis was performed for six patients (BRT=3, TC=3), beginning with cluster analysis to evaluate whether changes in peripheral blood gene expression varied according to treatment or prognosis. Gene ontology analysis characterized expression profiles in survivors and distinguished treatment effects. Alterations in the type I, II, and III interferon signatures were also assessed.
Results: In the TC-Tx group, four of seven patients succumbed to RP-ILD, whereas all seven BRT-Tx patients survived the 12-month observation period. Only one BRT-Tx patient required combined rescue therapies, including plasma exchange, and one case of unexplained limbic encephalitis (LE) occurred. Cytomegalovirus reactivation was observed in both groups (BRT: 5/7; TC: 6/7). Transcriptomic analysis revealed no treatment-specific clustering of differentially expressed genes (DEGs) before and after therapy. However, survivors and nonsurvivors formed distinct clusters, with survivors showing significant posttreatment suppression of B-cell-related gene expression. Moreover, interferon signature scores were significantly lower after treatment in survivors than in nonsurvivors. BRT-Tx effectively suppressed B-cell-mediated immune responses and maintained a low interferon signature, while TC-Tx resulted in nonspecific gene suppression, and in nonsurvivors, an elevated interferon signature was observed.
Conclusion: BRT-Tx has the potential to improve survival in MDA5-DM patients by effectively targeting hyperactive immune pathways. The combination of rituximab and tacrolimus is expected to disrupt B-cell?T-cell interactions and reduce autoantibody production, whereas baricitinib may suppress both IFN and GM-CSF signaling, regulating excessive autoimmunity mediated by cells such as macrophages. Unlike TC-Tx, BRT-Tx avoids cyclophosphamide-associated risks such as infertility and secondary malignancies. Future randomized controlled trials are warranted to validate its efficacy and safety. en-copyright= kn-copyright= en-aut-name=TokunagaMoe en-aut-sei=Tokunaga en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaiYu en-aut-sei=Nakai en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoYoshiharu en-aut-sei=Sato en-aut-mei=Yoshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiratsukaMitori en-aut-sei=Hiratsuka en-aut-mei=Mitori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoYoshinori en-aut-sei=Matsumoto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakatsueTakeshi en-aut-sei=Nakatsue en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaekiTakako en-aut-sei=Saeki en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmayaharaTakatsune en-aut-sei=Umayahara en-aut-mei=Takatsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KoyamaYoshinobu en-aut-sei=Koyama en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Division of Rheumatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=DNA Chip Research Inc., Medical Laboratory kn-affil= affil-num=4 en-affil=DNA Chip Research Inc., Medical Laboratory kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Division of Rheumatology and Nephrology, Department of Internal Medicine, Nagaoka Red Cross Hospital kn-affil= affil-num=7 en-affil=Division of Rheumatology and Nephrology, Department of Internal Medicine, Nagaoka Red Cross Hospital kn-affil= affil-num=8 en-affil=Division of Dermatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Division of Rheumatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= en-keyword=anti-MDA5 antibody-positive dermatomyositis (MDA5-DM) kn-keyword=anti-MDA5 antibody-positive dermatomyositis (MDA5-DM) en-keyword=JAK inhibitor kn-keyword=JAK inhibitor en-keyword=baricitinib kn-keyword=baricitinib en-keyword=rituximab kn-keyword=rituximab en-keyword=multitargeted treatment kn-keyword=multitargeted treatment en-keyword=IFN signature kn-keyword=IFN signature en-keyword=transcriptome analysis kn-keyword=transcriptome analysis END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=27481 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between proteinuria and mineral metabolism disorders in chronic kidney disease: the Japan chronic kidney disease database extension (J-CKD-DB-Ex) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic kidney disease-mineral and bone disorder (CKD-MBD) are recognized as a systemic disease affecting the prognosis of patients with CKD. Proper management of CKD-MBD is important to improve the prognosis of patients with CKD. Although proteinuria is recognized as a poor prognostic factor in these patients, few reports have examined its association with CKD-MBD. We examined the association between proteinuria and CKD-MBD using data from the Japan Chronic Kidney Disease Database Extension (J-CKD-DB-Ex). Among the patients registered in the J-CKD-DB-Ex, 30,977 with CKD stages G2?G5 who had serum creatinine, albumin, calcium, and phosphate concentrations measured at least once and urinalysis performed were included. The patients were divided into four groups (negative, 1+, 2+, and 3+) according to the degree of proteinuria. The association between proteinuria and CKD-MBD was examined by a logistic regression analysis. In a model adjusted for age, sex, diabetes, and the estimated glomerular filtration rate (eGFR), the odds ratio of the 3?+?group compared with the negative group significantly increased to 2.67 (95% confidence interval, 2.29?3.13) for hyperphosphatemia, 2.68 (1.94?3.71) for hypocalcemia, and 1.56 (1.24?1.98) for hypomagnesemia. Proteinuria is associated with hyperphosphatemia, hypocalcemia, and hypomagnesemia in patients with CKD independently of eGFR. en-copyright= kn-copyright= en-aut-name=ShimamotoSho en-aut-sei=Shimamoto

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although rare, neurotrauma has been documented as a potential risk of high-speed, high-acceleration amusement park rides such as roller coasters. These attractions generate rapid acceleration, deceleration, sharp turns, and significant gravitational forces, which may stress the central nervous system and cerebrovascular structures. This review analyzed pediatric stroke cases (children 15?years old or younger) linked to roller-coaster rides reported in PubMed and summarized the key mechanisms and clinical features associated with such neurotrauma. Documented complications include internal and vertebral carotid artery dissections, with or without stroke, subdural hemorrhage, intraparenchymal hemorrhage, and post-traumatic migraines. The aim of this review is to alert healthcare providers to the possibility of stroke induced by roller-coaster rides, emphasizing the importance of timely diagnosis and management to prevent adverse outcomes. Key considerations include the recognition of risk factors, public education on potential risks, and strategies for preventing complications in at-risk populations. Although intracranial hemorrhage from roller-coaster rides is rare, individuals with predisposing conditions, such as prior head trauma or vascular abnormalities, should be evaluated carefully when presenting with neurological symptoms after such activities. en-copyright= kn-copyright= en-aut-name=MorikawaTomoki en-aut-sei=Morikawa en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokiokaKohei en-aut-sei=Tokioka en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=amusement parks kn-keyword=amusement parks en-keyword=brain injuries kn-keyword=brain injuries en-keyword=carotid artery dissection kn-keyword=carotid artery dissection en-keyword=stroke kn-keyword=stroke en-keyword=vertebral artery dissection kn-keyword=vertebral artery dissection END start-ver=1.4 cd-journal=joma no-vol=2025 cd-vols= no-issue=1 article-no= start-page=e240121 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adult hypophosphatasia presenting with recurrent acute joint pain en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypophosphatasia (HPP) is a genetic disorder due to pathological variants in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (ALP). HPP is typically associated with bone-related symptoms, such as bone deformity, fractures and bone pain in children, but can appear in adults with symptoms resembling arthritis. A 22-year-old male experienced repeated and severe sudden attacks of joint pain in the elbows and knees. Magnetic resonance imaging and joint ultrasonography showed joint effusions indicating chronic inflammation. Blood biochemical tests revealed a remarkably low serum ALP level, and repeated examination confirmed a sustained low ALP level; urine phosphoethanolamine, plasma inorganic pyrophosphate and plasma pyridoxal-5′-phosphate levels were elevated, raising concern for HPP. While the patient had no history of premature loss of primary teeth, fragility fractures, muscle weakness or abnormalities in growth, genetic testing revealed a likely pathogenic and a pathogenic heterozygous variant in the ALPL gene, i.e., c.979T>C (p.Phe327Leu) and c.1559del (p.Leu520Argfs), confirming HPP. Additional genetic testing of his parents showed a heterozygous c.1559del variant in his father and a heterozygous c.979T>C variant in his mother. A diagnosis of adult HPP due to compound heterozygous mutations was therefore confirmed. Enzyme replacement therapy with asfotase alfa was then introduced; no attacks of arthralgia occurred in the 1-year period since then. This case highlights the possibility of HPP in adults who present clinically with repeated joint symptoms and low serum ALP levels but without bone-related symptoms. en-copyright= kn-copyright= en-aut-name=YoshidaHayao en-aut-sei=Yoshida en-aut-mei=Hayao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiTakaaki en-aut-sei=Murakami en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaAtsubumi en-aut-sei=Ogawa en-aut-mei=Atsubumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SunouchiTakashi en-aut-sei=Sunouchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HidakaNaoko en-aut-sei=Hidaka en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItoNobuaki en-aut-sei=Ito en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MurakamiHiromi en-aut-sei=Murakami en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawasakiHidenori en-aut-sei=Kawasaki en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakajimaKatsumi en-aut-sei=Nakajima en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YabeDaisuke en-aut-sei=Yabe en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamamotoTaizo en-aut-sei=Yamamoto en-aut-mei=Taizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= affil-num=2 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= affil-num=3 en-affil=Department of Rheumatology and Clinical Immunology, Kyoto University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Division of Nephrology and Endocrinology, The University of Tokyo Hospital kn-affil= affil-num=5 en-affil=Division of Nephrology and Endocrinology, The University of Tokyo Hospital kn-affil= affil-num=6 en-affil=Osteoporosis Center, The University of Tokyo Hospital kn-affil= affil-num=7 en-affil=Department of Genomic Medicine, Kyoto University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Genomic Medicine, Kyoto University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= affil-num=11 en-affil=Department of Diabetes, Endocrinology and Nutrition, Kyoto University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= en-keyword=hypophosphatasia kn-keyword=hypophosphatasia en-keyword=genetic disorders kn-keyword=genetic disorders en-keyword=bone kn-keyword=bone END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=6 article-no= start-page=e098532 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Protocol for a multicentre, open-label, dose-escalation phase I/II study evaluating the tolerability, safety, efficacy and pharmacokinetics of repeated continuous intravenous PPMX-T003 in patients with aggressive natural killer cell leukaemia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Aggressive natural killer cell leukaemia (ANKL) is a rare form of NK cell lymphoma with a very low incidence and poor prognosis. While multi-agent chemotherapy including L-asparaginase has been used to treat ANKL patients, they often cannot receive adequate chemotherapy at diagnosis due to liver dysfunction. PPMX-T003, a fully human monoclonal antibody targeting the transferrin receptor 1, shows promise in treating ANKL by helping patients recover from fulminant clinical conditions, potentially enabling a transition to chemotherapy. This study aimed to evaluate the tolerability, safety, efficacy, and pharmacokinetics of repeated continuous intravenous PPMX-T003 in patients with ANKL.
Methods and analysis This multicentre, open-label, dose-escalation phase I/II study will be conducted at nine hospitals in Japan. Patients diagnosed with ANKL (whether as a primary or recurrent disease) and exhibiting abnormal liver function or hepatomegaly due to the primary disease will be included. The primary endpoint is the tolerability and safety of repeated continuous intravenous administration of PPMX-T003 in the first course, based on adverse events and dose-limiting toxicities. PPMX-T003 will be administered as a continuous intravenous infusion every 24?hours for five consecutive days, followed by a 2-day break. Pretreatment will be provided to minimise the risk of infusion-related reactions. Initial doses of PPMX-T003 will be 0.5, 1.0 or 2.0 mg/kg, with subsequent dose increases determined by the Data and Safety Monitoring Committee. The sample size is set at seven participants, with enrolment increased to up to 12 participants if dose-limiting toxicities occur, based on feasibility due to the rarity of ANKL.

Some of the unique features commonly seen in HCRC cases include early age of onset, synchronous/metachronous cancer occurrence, and multiple cancers in other organs. These characteristics require different management approaches, including diagnosis, treatment or surveillance, from those used in the management of sporadic colorectal cancer. Accurate diagnosis of HCRC is essential because it enables targeted surveillance and risk reduction strategies that improve patient outcomes. Recent genetic advances revealed several causative genes for polyposis and non-polyposis syndromes. The Japanese Society for Cancer of the Colon and Rectum (JSCCR) first published guidelines for the management of HCRC in 2012, with subsequent revisions every 4 years. The 2024 update to the JSCCR guidelines for HCRC was developed by meticulously reviewing evidence from systematic reviews and the consensus of the JSCCR HCRC Guidelines Committee, which includes representatives from patient advocacy groups for FAP and Lynch syndrome. These guidelines provide an up-to-date summary of HCRC, along with clinical recommendations for managing FAP and Lynch syndrome. en-copyright= kn-copyright= en-aut-name=TanakayaKohji

Eleven Patients With 32- to 49-Year Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Photocoagulation or cryocautery, or their combinations, are the standard of care for retinopathy of prematurity at the recommended timing, which is based on the International Classification of Retinopathy of Prematurity. In Japan, the effectiveness of xenon-arc photocoagulation and cryocautery in retinopathy of prematurity was reported on an empirical basis first in 1968, and became the standard of care in retinopathy of prematurity in the 1970s, 10 years earlier compared with the other countries. In this study, we reported the up to 49 years visual outcome of 11 patients with retinopathy of prematurity who underwent xenon-arc photocoagulation and cryocautery in the 1970s.
Methods: A retrospective review was made on the medical records of 11 consecutive patients who underwent xenon-arc photocoagulation for retinopathy of prematurity in the years 1974 to 1980, and were followed up until the period from 2009 to 2025. The birthweight ranged from 865 g to 2300 g at a median of 1350 g, and the gestational age at birth ranged from 27 weeks to 36 weeks at a median of 30 weeks. The corrected gestational age at the time of photocoagulation ranged from 32 weeks to 53 weeks, with a median of 37 weeks. Oxygen was given to all 11 patients, except for one who was born in the earliest year 1974. The retinopathy of prematurity was at stage 3 in both eyes of seven patients, with plus disease signs in four patients, at stage 2 with and without plus disease in two patients, at stage 2 and stage 3 in each eye of one patient, and at stage 1 with plus disease in both eyes of one patient. The entire 360-degree photocoagulation was given in seven patients, while partial photocoagulation was applied in four patients. Additional cryocautery was applied in six patients.
Results: The age at the last visit ranged from 32 to 49 years with a median of 46 years. At the last visit, seven patients showed the best-corrected visual acuity in decimals of 0.8 or better in both eyes. One dizygotic twin showed no light perception in the phthisic right eye and 0.1 in the left eye with macular degeneration and nystagmus after he underwent cataract surgery at the age of 34 years. The other twin had the best-corrected visual acuity of 0.5 in the right eye and 0.02 in the left eye due to macular degeneration after he underwent cataract surgeries in both eyes at the age of 36 years. Two patients developed rhegmatogenous retinal detachment in one eye at the age of 44 and 41 years, respectively, and underwent vitrectomy with silicone oil tamponade, resulting in visual acuity of 0.1 and 0.3, respectively. Two patients experienced vitreous hemorrhage in one eye, which was absorbed spontaneously at the ages of 37 years and 42 years, respectively. One patient underwent partial scleral buckling for localized rhegmatogenous retinal detachment. No patient used intraocular pressure-lowering eyedrops.
Conclusion: Most patients with xenon-arc photocoagulation for retinopathy of prematurity in the 1970s maintained standard levels of visual acuity up to 49 years in the follow-up. Cataract, retinal detachment, and vitreous hemorrhage were noted as late complications and were coped with on an individual basis. The conclusion would have a meaning, even though not novel, that the patients with retinopathy of prematurity would have benefited from the xenon-arc photocoagulation and cryocautery. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoNobuhiko en-aut-sei=Matsuo en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Ophthalmology, Okayama University Medical School kn-affil= en-keyword=1970s kn-keyword=1970s en-keyword=cataract kn-keyword=cataract en-keyword=cryocautery kn-keyword=cryocautery en-keyword=japan kn-keyword=japan en-keyword=late complications kn-keyword=late complications en-keyword=neonatology kn-keyword=neonatology en-keyword=retinal detachment kn-keyword=retinal detachment en-keyword=retinopathy of prematurity kn-keyword=retinopathy of prematurity en-keyword=vitreous hemorrhage kn-keyword=vitreous hemorrhage en-keyword=xenon-arc photocoagulation kn-keyword=xenon-arc photocoagulation END start-ver=1.4 cd-journal=joma no-vol=81 cd-vols= no-issue= article-no= start-page=152587 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The diagnostic utility and frequency of CD56 expression in plasma cell myeloma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plasma cell myeloma (PCM) is a hematological malignancy characterized by systemic proliferation of neoplastic plasma cells within the bone marrow. Diagnosis requires clinical findings and immunohistochemical staining, including CD138, CD79a, cyclin D1, immunoglobulin κ (Igκ), and λ (Igλ). However, CD79a and cyclin D1 have limited sensitivity and specificity, and Igκ/Igλ assessment is often difficult due to overstaining. Therefore, more reliable antibodies are needed to accurately diagnose PCM. In this study, we examined the diagnostic utility of CD56 expression in PCM. We retrospectively performed immunostaining for CD138, CD56, CD79a, cyclin D1, Igκ, and Igλ in bone marrow samples from 116 patients with PCM.
CD56 expression was observed in 85/116 cases (73.3 %), CD79a was downregulated in 46/116 cases (39.7 %), and cyclin D1 expression was observed in 42/116 cases (36.2 %). The expression of CD56 was significantly higher than that of CD79a and cyclin D1 (both p < 0.001). The combination of two antibodies resulted in the highest detection rate when combining CD56 and CD79a (105/116, 90.5 %), which was significantly higher than the detection rates of CD56 and cyclin D1 (93/116, 80.2 %) and CD79a and cyclin D1 (75/116, 64.7 %) (both p < 0.001). In contrast, lymphoplasmacytic lymphoma and marginal zone lymphoma lacked CD56 and cyclin D1 expression. Furthermore, in cases where light chain restriction was undetectable (11/116, 9.5 %), all could be diagnosed as PCM based on CD56, CD79a, and cyclin D1. Among these, CD56 showed the highest detection rate (8/11, 72.7 %).
These findings highlight CD56 as a helpful marker for PCM diagnosis and support further clinical research.

In the present study, we focused on the role of reactive oxygen species (ROS) produced by the NADPH oxidase Dual oxidase (Duox) during cricket leg regeneration. The results showed that ROS levels were upregulated during leg regeneration and decreased by DuoxRNAi. In DuoxRNAi nymphs, wound closure and scab formation were incomplete 2?days after amputation, and hypertrophy occurred in the distal region of the regenerating legs at 5?days after amputation. In addition, the hypertrophic phenotype was induced by DuoxARNAi and NADPH oxidase inhibitor treatment. During hypertrophy, haemocytes, including plasmatocytes, oenocytoids and granulocytes, accumulated. Proliferation of haemocytes in regenerating legs was not increased by DuoxRNAi; however, haemocyte accumulation was regulated by the Spatzle (Spz) family molecules, which are Toll receptor ligands. As the exoskeleton of DuoxRNAi nymphs was thinner than that of the control, excessive haemocyte accumulation can cause hypertrophy in DuoxRNAi nymphs. Thus, Duox-derived ROS are involved in wound healing and haemocyte accumulation through the Spz/Toll signalling pathway during leg regeneration in crickets. en-copyright= kn-copyright= en-aut-name=Okumura-HironoMisa en-aut-sei=Okumura-Hirono en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaYoshimasa en-aut-sei=Hamada en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Regeneration kn-keyword=Regeneration en-keyword=Reactive oxygen species (ROS) kn-keyword=Reactive oxygen species (ROS) en-keyword=NADPH oxidase (Nox) kn-keyword=NADPH oxidase (Nox) en-keyword=Dual oxidase (Duox) kn-keyword=Dual oxidase (Duox) en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Gryllus bimaculatus kn-keyword=Gryllus bimaculatus 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=20251124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the small-field output factor in eclipse modeling methods using representative beam and measured data with averaged ionization chamber and diode detector measurements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Beam modeling for radiotherapy treatment planning systems (RTPS) can be performed using representative beam data (RBD) or direct measurements. However, RBD typically excludes output factor (OPF) measurements for fields smaller than 3 × 3 cm2. The Eclipse treatment planning system addresses this limitation by incorporating measured OPF data for fields as small as 1 × 1 cm2. Although existing studies have primarily examined the accuracy of small-field OPFs for plastic scintillator detectors, studies directly comparing the OPF values obtained through RBD modeling with and without OPF measurements for small field sizes are limited. Therefore, this study proposes a novel measurement approach using data averaged from an ion chamber and diode detector for small-field dosimetry to provide critical insights into the integration of OPFs for these small field sizes in RBD-based beam modeling. We systematically evaluated the impact of small-field OPF measurements on beam modeling accuracy by comparing three distinct approaches: (1) RBD-based modeling without small-field OPF data, (2) RBD-based modeling incorporating measured small-field OPF data, and (3) modeling based solely on measured data, with and without the inclusion of 1 × 1 cm2 field sizes. In addition, we compared OPF values obtained from a W2 plastic scintillator detector with the averaged OPF values from a PinPoint 3D ion chamber and EDGE diode detector across multiple beam energies and flattening filter-free (FFF) configurations. Our analysis included field sizes ranging from 1 × 1 cm2 to 40 × 40 cm2. The results demonstrated that for square fields, OPF calculation differences between RBD modeling with and without measured data were < 1.5%, < 4.5%, and < 4.5% at 1 × 1 cm2, and < 0.5%, < 1.5%, and < 1.5% at 2? × ?2 cm2, respectively. The RBD group exhibited a trend in which the OPF difference increased with the expansion of the irradiation field size. Notably, the most significant variations between modeling approaches occurred along the upper jaw expansion direction in rectangular fields. This suggests that a thorough evaluation is necessary for modeling results with an OPF??? 1 × 1 cm2. This study highlights the advantages and disadvantages of beam modeling using measured OPF and RBD, providing valuable insights for future facilities that rely solely on RBD for beam modeling. en-copyright= kn-copyright= en-aut-name=NishiokaKunio en-aut-sei=Nishioka en-aut-mei=Kunio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuniiYuki en-aut-sei=Kunii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoYuichi en-aut-sei=Sakamoto en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamotoAkira en-aut-sei=Nakamoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiShotaro en-aut-sei=Takahashi en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= en-keyword=Beam modeling kn-keyword=Beam modeling en-keyword=Plastic scintillator detector kn-keyword=Plastic scintillator detector en-keyword=Small irradiation field kn-keyword=Small irradiation field en-keyword=Output factor kn-keyword=Output factor END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Role of the Mylohyoid Line in the Spread of Mandibular Odontogenic Deep Neck Infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Although mandibular odontogenic deep neck infections are occasionally fatal, the transmission pathway has not been elucidated.
Materials and Methods: This multicenter retrospective study was comprised of the patients of both sexes who were over 18?years of age and who had mandibular odontogenic deep neck abscesses. The patients' characteristics, laboratory tests, and radiographic findings were analyzed.
Results: One hundred eighteen patients with mandibular odontogenic deep neck abscesses were included. Bone resorption superior to the mylohyoid line and the related abscess formation in submandibular space or submental space were both significantly associated with the presence of sublingual space abscess. In addition, the type of causative tooth was not a risk factor for abscess formation in both the sublingual space and “submandibular or submental” space.
Conclusions: When an odontogenic lesion is located superior to the mylohyoid line, the abscess tends to initially form in the sublingual space and subsequently spread to the submandibular or submental space. Since any mandibular tooth can lead to abscess formation in these regions, oral and maxillofacial surgeons should carefully assess the anatomical position of the lesion and accurately identify the causative tooth. en-copyright= kn-copyright= en-aut-name=IwataEiji en-aut-sei=Iwata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataKyoichi

marrow-derived stromal cells (SB623) with voluntary and forced exercise in a rat model of ischemic stroke en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ischemic stroke results in significant long-term disability and mortality worldwide. Although existing therapies, such as recombinant tissue plasminogen activator and mechanical thrombectomy, have shown promise, their application is limited by stringent conditions. Mesenchymal stem cell (MSC) transplantation, especially using SB623 cells (modified human bone marrow-derived MSCs), has emerged as a promising alternative, promoting neurogenesis and recovery. This study evaluated the effects of voluntary and forced exercise, alone and in combination with SB623 cell transplantation, on neurological and psychological outcomes in a rat model of ischemic stroke. Male Wistar rats that had undergone middle cerebral artery occlusion (MCAO) were divided into six groups: control, voluntary exercise (V-Ex), forced exercise (F-Ex), SB623 transplantation, SB623 + V-Ex, and SB623 + F-Ex. Voluntary exercise was facilitated using running wheels, while forced exercise was conducted on treadmills. Neurological recovery was assessed using the modified neurological severity score (mNSS). Psychological symptoms were evaluated through the open field test (OFT) and forced swim test (FST), and neurogenesis was assessed via BrdU labeling. Both exercise groups exhibited significant changes in body weight post-MCAO. Both exercises enhanced the treatment effect of SB623 transplantation. The forced exercise showed a stronger treatment effect on ischemic stroke than voluntary exercise alone, and the sole voluntary exercise improved depression-like behavior. The SB623 + F-Ex group demonstrated the greatest improvements in motor function, infarct area reduction, and neurogenesis. The SB623 + V-Ex group was most effective in alleviating depression-like behavior. Future research should optimize these exercise protocols and elucidate the underlying mechanisms to develop tailored rehabilitation strategies for stroke patients. en-copyright= kn-copyright= en-aut-name=NagaseTakayuki en-aut-sei=Nagase en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawauchiSatoshi en-aut-sei=Kawauchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugaharaChiaki en-aut-sei=Sugahara en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyakeHayato en-aut-sei=Miyake en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaiKoji en-aut-sei=Kawai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanimotoShun en-aut-sei=Tanimoto en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SaijoTomoya en-aut-sei=Saijo en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Ischemic stroke kn-keyword=Ischemic stroke en-keyword=Post-stroke depression kn-keyword=Post-stroke depression en-keyword=Regenerative medicine kn-keyword=Regenerative medicine en-keyword=Rehabilitation kn-keyword=Rehabilitation en-keyword=SB623 kn-keyword=SB623 END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=1 article-no= start-page=95 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of a large venous ring around the mandibular condyle en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anatomical details regarding venous drainage of the head and neck are an important matter for surgeons to avoid unnecessary complications such as hemorrhage. This report describes a case of the large venous ring around the mandibular condyle found in the cadaver. The left maxillofacial region of a latex-injected embalmed male cadaver (82 years of age at death) was dissected. The large two maxillary veins ran lateral to the capsule and superior to the mandibular notch and coursed posteroinferiorly to merge, and one trunk was formed at the posterior border of the ramus. It then received the superficial temporal vein superiorly to form the retromandibular vein (RMV). In addition, three maxillary veins were drained from the pterygoid venous plexus (PVP), medial to the ramus, one maxillary vein drained from the PVP into the RMV trunk, while two maxillary veins drained from the PVP into the anterior division of the RMV. All five large veins lateral and medial to the condyle drained from the PVP into the RMV. The knowledge of such an anatomical variation might prevent intraoperative bleeding in the temporomandibular joint region. en-copyright= kn-copyright= en-aut-name=NishiKeitaro en-aut-sei=Nishi en-aut-mei=Keitaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkuiTatsuo en-aut-sei=Okui en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KusukawaJingo en-aut-sei=Kusukawa en-aut-mei=Jingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TubbsR.

We assessed ChatGPT responses to 149 multiple-choice questions written in Japanese for the board qualification examination of the JSOMR for the 3 years from 2020 to 2022. The questions were directly entered into ChatGPT-3.5 and ChatGPT-4 models manually one by one as a prompt. The accuracy rate was calculated and classified by year, type of multiple-choice question, and level of intellectual ability, and significant differences were noted. The accuracy rate of GPT-3.5 for the 3 years was 45.0% (51.0% for 2020, 34.0% for 2021, and 50.0% for 2022), while the accuracy rate of GPT-4 was 68.5% (73.5% for 2020, 62.0% for 2021, and 70.0% for 2022) for the board qualification examination of the JSOMR. GPT-4 had a significantly higher accuracy rate than GPT-3.5 in each year. On performance classified by the type of multiple-choice questions, GPT-4 performed significantly better than GPT-3.5. However, neither model performed well with questions that required interpretation or knowledge of Japanese law. The performance of GPT-4 was significantly superior to GPT-3.5 in the board qualification examination of the JSOMR, suggesting that the use of Chat GPT, especially ChatGPT-4, would be effective as a tool for learning and preparing for the examination. en-copyright= kn-copyright= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawazuToshiyuki en-aut-sei=Kawazu en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HisatomiMiki en-aut-sei=Hisatomi en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujikuraMamiko en-aut-sei=Fujikura en-aut-mei=Mamiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NambaYuri en-aut-sei=Namba en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaSuzuka en-aut-sei=Yoshida en-aut-mei=Suzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanagiYoshinobu en-aut-sei=Yanagi en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AsaumiJunichi en-aut-sei=Asaumi en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=9 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ChatGPT kn-keyword=ChatGPT en-keyword=GPT-3.5 kn-keyword=GPT-3.5 en-keyword=GPT-4 kn-keyword=GPT-4 en-keyword=Generative AI kn-keyword=Generative AI en-keyword=Large language model kn-keyword=Large language model en-keyword=Japanese Society for Oral and Maxillofacial Radiology kn-keyword=Japanese Society for Oral and Maxillofacial Radiology END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=127 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250315 dt-online= en-article= kn-article= en-subject= 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? 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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=DSOK-0011 Potentially Regulates Circadian Misalignment and Affects Gut Microbiota Composition in Activity-Based Anorexia Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Anorexia nervosa (AN) is a metabolic-psychiatric disorder characterized by severe weight loss, hypercortisolemia, and hypothalamic?pituitary?adrenal (HPA) axis activation. In this study, we investigated the effect of inhibiting cortisol regeneration via the enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) on the pathophysiology of AN.
Method: Female C57BL/6J mice underwent a 7-day activity-based anorexia (ABA) paradigm, involving 3?h daily feeding and free access to wheels, until 25% body weight loss or experiment completion. Mice were orally treated once daily with a potent 11β-HSD1 inhibitor, DSOK-0011, or vehicle. Body weight, food intake, and activity transitions were recorded; plasma corticosterone and cholesterol levels were measured using a fluorometric assay; gut microbiota were analyzed using 16S rRNA sequencing; and hippocampal glial cells were analyzed using immunohistochemistry.
Results: DSOK-0011-treated mice exhibited a modest but significant increase in postprandial wheel-running activity compared to baseline (4?5?p.m., p?=?0.018; 5?6?p.m., p?=?0.043), whereas vehicle-treated mice showed higher preprandial activity (9?10?a.m., p?=?0.0229). Gut microbiota analysis revealed increased alpha diversity in ABA mice, with a specific enrichment of the Lachnospiraceae family in the DSOK-0011 group. However, DSOK-0011 did not significantly affect body weight, food intake, corticosterone, and lipid levels, or hippocampal glial cell populations.
Conclusion: Inhibition of 11β-HSD1 by DSOK-0011 was associated with microbiota alterations and subtle shifts in activity timing under energy-deficient conditions. These findings suggest that peripheral glucocorticoid metabolism may influence microbial and behavioral responses in the ABA model, although its metabolic impact appears limited in the acute phase. en-copyright= kn-copyright= en-aut-name=KawaiHiroki en-aut-sei=Kawai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WadaNanami en-aut-sei=Wada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoShinji en-aut-sei=Sakamoto en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyazakiKenji en-aut-sei=Miyazaki en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoTaro en-aut-sei=Kato en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriuchiYoshihiro en-aut-sei=Horiuchi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KiriiHiroshi en-aut-sei=Kirii en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NguyenHoang Duy en-aut-sei=Nguyen en-aut-mei=Hoang Duy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HinotsuKenji en-aut-sei=Hinotsu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhyaYoshio en-aut-sei=Ohya en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AsadaTakahiro en-aut-sei=Asada en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YokodeAkiyoshi en-aut-sei=Yokode en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkahisaYuko en-aut-sei=Okahisa en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MiyazakiHaruko en-aut-sei=Miyazaki en-aut-mei=Haruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=OohashiToshitaka en-aut-sei=Oohashi en-aut-mei=Toshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Sumitomo Pharma Co.

Notably, blocking β1 receptors can lead to organ protection through anti?inflammatory and anti?apoptotic effects. Additionally, although the β1 receptor pathway is blocked by the β1 blocker, the β2 receptor pathway may be preserved and activate the 5' adenosine monophosphate?activated protein kinase (AMPK) pathway. The present study aimed to examine whether administration of the β1 blocker landiolol could achieve lung protection in a model of HSR?ALI, alongside improvements in inflammation and apoptosis. Male Sprague?Dawley rats underwent hemorrhage keeping their mean arterial pressure at 30 mmHg for 1 h. Resuscitation by reinfusion was initiated to restore blood pressure to pre?hemorrhage levels for >15 min, followed by a 45?min stabilization period to create the HSR?ALI model. Landiolol (100 mg/kg/min) or saline was continuously administered after resuscitation. The lung tissues, which were collected for assessing inflammation and apoptosis?related damage, underwent analyses, including histological examination, neutrophil count, assessment of lung wet/dry weight ratio, detection of the mRNA levels of tumor necrosis factor?α (TNF?α) and inducible nitric oxide synthase (iNOS), identification of terminal deoxynucleotidyl transferase dUTP nick?end labeling (TUNEL)?positive cells, and evaluation of caspase?3 expression. In addition, phosphorylated AMPKα (pAMPKα) expression was tested via western blotting. Compared with the HSR/saline group, the HSR/landiolol group demonstrated a reduction in lung tissue damage score, and significant reductions in neutrophil count, lung wet/dry weight ratio, lung TNF?α and iNOS mRNA levels, TUNEL?positive cells and cleaved caspase?3 expression. Furthermore, landiolol administration following HSR treatment increased pAMPKα expression. No significant hypotension occurred between the HSR/landiolol and HSR/saline groups; and blood loss did not differ significantly between the groups. In conclusion, landiolol administration after HSR reduced lung inflammation and apoptosis, suggesting a potential improvement in tissue damage. Furthermore, pAMPKα activation in the HSR/landiolol group may be the mechanism underlying the pulmonary protective effects of landiolol. en-copyright= kn-copyright= en-aut-name=SakamotoRisa en-aut-sei=Sakamoto en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuHiroko en-aut-sei=Shimizu en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraRyu en-aut-sei=Nakamura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LuYifu en-aut-sei=Lu en-aut-mei=Yifu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiYaqiang en-aut-sei=Li en-aut-mei=Yaqiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriEmiko en-aut-sei=Omori en-aut-mei=Emiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiToru en-aut-sei=Takahashi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Medical School kn-affil= affil-num=4 en-affil=Department of Human Anatomy, Shantou University Medical College kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Anesthesiology, Okayama Saidaiji Hospital kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=HSR kn-keyword=HSR en-keyword=lung injury kn-keyword=lung injury en-keyword=landiolol kn-keyword=landiolol en-keyword=β1 blocker kn-keyword=β1 blocker en-keyword=inflammation kn-keyword=inflammation en-keyword=apoptosis kn-keyword=apoptosis 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=20250909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current Status of Continuous Renal Replacement Therapy in Japanese Intensive Care Units: A Multicenter Retrospective Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Continuous renal replacement therapy (CRRT) is often performed for critically ill patients in intensive care units (ICUs), but its optimal indication and settings have yet to be determined. Thus, we aimed to describe the current status of CRRT in Japan through a multicenter retrospective observational study. Methods: Adult ICU patients receiving CRRT at 18 tertiary hospitals in Japan (up to 100 patients from each hospital over the past year) were retrospectively enrolled. Patients receiving CRRT for <24 h or intermittent renal replacement therapy together with CRRT were excluded. The primary outcomes were the temporal changes in the electrolyte levels, acid-base balance, and uremia-related small solute concentrations. The secondary outcomes included potassium (K) and phosphate (P) supplementations during CRRT. Results: Altogether, 1,045 patients were enrolled. The median CRRT duration and dose were 4.4 days and 17.3 mL/kg/h, respectively. The electrolyte levels, acid-base balance, and uremia-related small solute concentrations returned to normal by day 4 of treatment. A total of 732 (70.0%) patients received K supplementation, and only a few patients had hypokalemia until day 5. Moreover, 414 (39.6%) patients received P supplementation, and approximately 30%?50% of the patients had hypophosphatemia until day 5. Conclusion: The CRRT dose in Japan was lower than that was recommended by the Kidney Disease: Improving Global Outcomes guideline. The electrolyte level abnormalities and acid-base imbalances of the studied patients were improved within 72?96 h of CRRT. Contrarily, K and P supplementations were common, indicating that the current CRRT solutions need to be modified. en-copyright= kn-copyright= en-aut-name=NakanoHidehiko en-aut-sei=Nakano

resource to disseminate virus taxonomy advances en-subtitle= kn-subtitle= en-abstract= kn-abstract=Taxonomic classification of cellular organisms requires the publication of descriptions and proposed names of species and the deposition of specimens. Virus taxonomy is developed through a different system of annual submission of formal taxonomy proposals (TPs) that can be submitted by anyone but are typically prepared by a study group appointed by the International Committee on Taxonomy of Viruses (ICTV) and consisting of experts on a particular group of viruses. These are initially evaluated by an expert subcommittee and by the executive committee (EC) of the ICTV. EC-approved TPs are then submitted for evaluation and a ratification vote by the wider ICTV membership. Following ratification, the new taxonomy is annually updated in the Master Species List, associated databases and bioinformatic resources. The process is consistent, creates traceability in assignments and supports a fully evaluated, hierarchical classification and nomenclature of all taxonomic ranks from species to realms. The structure also facilitates large-scale and coordinated changes to virus taxonomy, such as the recent introduction of a binomial species nomenclature.
TPs are available on the ICTV website after ratification, but they are not indexed in bibliographic databases and are not easily cited. Authors of TPs do not receive citation credit for adopted proposals, and their voluntary contributions are largely invisible in the published literature. For greater visibility of TPs and their authors, the ICTV will commence the annual publication of summaries of all TPs from each ICTV subcommittee. These summaries will provide a searchable compendium of all annual taxonomy changes and additions as well as direct links to the Master Species List and other ICTV bioinformatic resources. Their publication will provide due credit and citations for their authors, form the basis for disseminating taxonomy decisions and promote greater visibility and accessibility to taxonomy changes for the virology community. en-copyright= kn-copyright= en-aut-name=MayneRichard en-aut-sei=Mayne en-aut-mei=Richard kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SimmondsPeter en-aut-sei=Simmonds en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SmithDonald B. en-aut-sei=Smith en-aut-mei=Donald B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AdriaenssensEvelien M. en-aut-sei=Adriaenssens en-aut-mei=Evelien M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LefkowitzElliot J. en-aut-sei=Lefkowitz en-aut-mei=Elliot J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OksanenHanna M. en-aut-sei=Oksanen en-aut-mei=Hanna M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZerbiniFrancisco Murilo en-aut-sei=Zerbini en-aut-mei=Francisco Murilo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Alfenas-ZerbiniPoliane en-aut-sei=Alfenas-Zerbini en-aut-mei=Poliane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AylwardFrank O en-aut-sei=Aylward en-aut-mei=Frank O kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Freitas-Ast?aJuliana en-aut-sei=Freitas-Ast?a en-aut-mei=Juliana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HendricksonR.

To prevent further coastal erosion and damage, control structures like seawalls and breakwaters have been installed along vulnerable coastlines. However, it is crucial that these structures are regularly and thoroughly inspected for any abnormalities or deformations. At present, inspections are done manually by visual surveys which are time-consuming and inefficient. There is great potential to optimize this process using drone technology equipped with 3D laser scanners. In this study, we utilized a drone with a green laser scanner to inspect and diagnose control structures along the coast. We conducted surveys to determine the basic performance of this approach and used ICP algorithms to extract any deformations in vanishing wave blocks over two time periods. Our results showed high variability in basic performance due to the influence of waves during the surveys. However, we were still able to detect strain of around 50 cm in a submerged breakwater located 3 meters below the water's surface. Furthermore, an overall settlement of approximately 34 cm was observed in the vanishing wave blocks along with some localized movements. This demonstrates that drones can be successfully implemented for efficient inspection, diagnosis and detection of abnormalities and deformations in coastal structures that are extremely difficult to identify through visual surveys alone. The use of this advanced technology will allow for quicker identification of at-risk structures, enabling timely maintenance and prevention of further coastal erosion. en-copyright= kn-copyright= en-aut-name=SakamotoN. en-aut-sei=Sakamoto en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiyamaS. en-aut-sei=Nishiyama en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= en-keyword=Laser surveying kn-keyword=Laser surveying en-keyword=Green laser drone kn-keyword=Green laser drone en-keyword=3D point cloud kn-keyword=3D point cloud en-keyword=Coastal erosion control kn-keyword=Coastal erosion control en-keyword=ICP kn-keyword=ICP END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=11 article-no= start-page=1677 end-page=1685 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Cytoreductive Nephrectomy in the Immune Checkpoint Inhibitor Era: A Multicenter Collaborative Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: We aimed to evaluate overall survival (OS) and determine the optimal timing of cytoreductive nephrectomy (CN) in patients with metastatic renal cell carcinoma (mRCC) receiving immune checkpoint inhibitor (ICI)-based therapy.
Methods: This retrospective study reviewed medical records of 447 patients with mRCC treated with ICI at multiple Japanese institutions between January 2018 and August 2023. From this cohort, 178 patients with lymph node or distant metastases received either cytoreductive nephrectomy (CN group; n?=?72) or ICI therapy without cytoreductive nephrectomy (non-CN group; n?=?106) as first-line treatment.
Results: Median progression-free survival was 15.7?months, and median overall survival was 58.1?months. CN significantly improved OS, with the CN group's median OS not reached, compared to 29.6?months in the non-CN group (p?=?0.01). Deferred CN also showed improved survival outcomes. Poor prognostic factors for immediate CN included International Metastatic Renal Cell Carcinoma Database Consortium poor risk, sarcomatoid differentiation, and a high neutrophil-to-lymphocyte ratio.
Conclusions: We developed a prognostic model to guide patient selection for CN, emphasizing the need for personalized treatment strategies. en-copyright= kn-copyright= en-aut-name=NukayaTakuhisa

in cutaneous specimens after kidney transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clinical improvement in pigmentation is frequently observed after kidney transplantation. However, the underlying molecular and histological mechanisms remain unclear. We conducted a study to quantify the skin color change using a handheld reflected light colorimeter and to investigate protein expression changes in the skin before and after kidney transplantation. Paired skin biopsies were obtained from three patients who underwent kidney transplantation before and one month after transplantation. Protein expression was analyzed using iTRAQ-based quantitative proteomics. Differentially expressed proteins were identified and visualized using hierarchical clustering and volcano plots. Histopathological evaluation included hematoxylin and eosin (H&E), Masson’s trichrome, and immunohistochemical (IHC) staining for keratin (KRT) 7, KRT19, and MelanA. Skin pigmentation of the arms, ankles, and abdomen had significant L-value improvement after kidney transplantation. Proteomic profiling identified 2148 proteins, with six proteins showing significant differential expression after transplantation. Among them, KRT7, KRT19, and prostaglandin D2 synthase (PTGDS) were significantly downregulated, potentially reflecting reduced epithelial stress and systemic inflammation. H&E and Masson’s trichrome staining revealed a post-transplantation reduction in dermal pigmentation and collagen content. IHC showed decreased KRT7, KRT19, and MelanA expression after transplantation. Our results suggest that targeting KRT or prostaglandin pathways may offer new treatments for ESRD-related skin symptoms. en-copyright= kn-copyright= en-aut-name=TsuboiIchiro en-aut-sei=Tsuboi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuiYosuke en-aut-sei=Mitsui en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshinagaKasumi en-aut-sei=Yoshinaga en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamanoiTomoaki en-aut-sei=Yamanoi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SekitoTakanori en-aut-sei=Sekito en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaruyamaYuki en-aut-sei=Maruyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Inflammation and Immunity, Lerner Research Institute Cleveland Clinic kn-affil= affil-num=6 en-affil=Department of Inflammation and Immunity, Lerner Research Institute Cleveland Clinic kn-affil= affil-num=7 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Urology Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Cutaneous manifestations kn-keyword=Cutaneous manifestations en-keyword=Keratin kn-keyword=Keratin en-keyword=Skin color kn-keyword=Skin color en-keyword=Pigmentation kn-keyword=Pigmentation en-keyword=Prostaglandin D2 synthase kn-keyword=Prostaglandin D2 synthase en-keyword=Renal transplantation kn-keyword=Renal transplantation en-keyword=Dialysis kn-keyword=Dialysis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=185111 end-page=185124 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=Enhancing Protection Against Code Reuse Attacks on IoT Devices by Randomizing Function Addresses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most Internet of Things (IoT) devices currently in use are vulnerable to code reuse attacks because manufacturers typically deploy the same firmware across all devices. This uniformity enables attackers to craft a single exploit that can compromise multiple devices. To mitigate this risk, we propose a firmware diversification approach that creates multiple executable files with varying software compositions. Our approach introduces two complementary techniques: Function Address Reordering (FAR), which randomizes the order of functions within object files during compilation, and Object Address Reordering (OAR), which permutes the linking order of object files in the final executable. These techniques collectively diversify firmware instances without altering runtime behavior, making executing code reuse attacks significantly more difficult. By deploying firmware with diverse executable files, it is possible to enhance security without altering device behavior. We evaluate the effectiveness and limitations of the proposed methods when integrated into actual IoT firmware, assessing their resilience to code reuse attacks, impact on runtime behavior, and compilation overhead. Experimental results demonstrate that FAR and OAR significantly reduce the success rate of return-oriented programming attacks while incurring minimal performance overhead. This study offers a scalable, hardware-independent defense against code reuse attacks that increases resilience without a significant performance overhead, rendering it practical for widespread adoption in various IoT applications. en-copyright= kn-copyright= en-aut-name=SajiKazuma en-aut-sei=Saji en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniguchiHideo en-aut-sei=Taniguchi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Code reuse attack kn-keyword=Code reuse attack en-keyword=IoT firmware kn-keyword=IoT firmware en-keyword=software diversity kn-keyword=software diversity en-keyword=function reordering kn-keyword=function reordering en-keyword=LLVM kn-keyword=LLVM END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=1682012 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Maternal circulating GPIHBP1 levels and neonatal outcomes in patients with gestational diabetes mellitus: a pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The prevalence of gestational diabetes mellitus (GDM) is significantly increasing. Hyperglycaemia and dyslipidaemia have been demonstrated to contribute to endothelial dysfunction linked to foetal?placental circulation. Glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) is crucial for the lipolytic processing of TG-rich lipoproteins through the anchoring of lipoprotein lipase (LPL). In this study, circulating GPIHBP1 levels during pregnancy were evaluated, and their associations with hypertriglyceridaemia and the perinatal outcomes of GDM were evaluated.
Methods: This study included 12 pregnant women with GDM and 21 pregnant women with normal glucose tolerance (NGT).
Results: No significant differences in obstetrical outcomes were detected between the two groups. In participants with NGT, circulating GPIHBP1 levels were markedly lower in the 3rd trimester than in the 2nd trimester and at delivery. In women with GDM, circulating GPIHBP1 levels were unchanged during the 3rd trimester, and circulating GPIHBP1 levels throughout the 3rd trimester were negatively correlated with neonatal birth weight percentile and umbilical venous pO2 (ρ=-0.636, p=0.026; ρ=-0.657, p=0.020).
Discussion: Our findings suggest a possible association between circulating GPIHBP1 levels and perinatal outcomes in patients with GDM. en-copyright= kn-copyright= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurookaNaoko en-aut-sei=Kurooka en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) kn-keyword=glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) en-keyword=gestational diabetes mellitus (GDM) kn-keyword=gestational diabetes mellitus (GDM) en-keyword=perinatal outcomes kn-keyword=perinatal outcomes en-keyword=placenta kn-keyword=placenta en-keyword=triglyceride (TG) kn-keyword=triglyceride (TG) END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=10 article-no= start-page=1626 end-page=1637 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Redefining AT1 Receptor PET Imaging: Introducing the Radiotracer [18F]DR29 en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND: AT1R (angiotensin II type 1 receptors) are central to the renin-angiotensin system and are involved in regulating blood pressure and renal physiology. This study introduces [18F]DR29, a fluorine-18-labeled radiotracer for positron emission tomography imaging, to enable noninvasive visualization of AT1R expression. Its potential applications in understanding AT1R-associated renal processes are explored in healthy and hypertensive rat models.
METHODS: Radiolabeling was established, and biodistribution studies were conducted on healthy Wistar rats with and without the AT1R antagonist candesartan and transporter inhibitors. Dynamic positron emission tomography imaging assessed tracer specificity, and feasibility for renal AT1R quantification was explored using a hypertensive rat model.
RESULTS: [18F]DR29 was radiolabeled with a yield of 36±6%. High kidney uptake was observed, significantly reduced by candesartan (kidney-to-blood ratio, 0.43±0.01 versus 4.54±1.59 in vehicle, where vehicle refers to saline without any treatment). Transporter inhibition protocols targeting organic anion transporting polypeptides (liver) and organic anion transporters (kidneys) successfully reduced radiotracer clearance, increasing the specific accumulation of [18F]DR29 in the kidneys and improving renal imaging contrast. Positron emission tomography imaging revealed rapid kidney uptake and stable retention over 2 hours. In hypertensive rats, kidney uptake was higher, aligning with AT1R expression levels.
CONCLUSIONS: These results support [18F]DR29 as a promising tool for the noninvasive evaluation of renal AT1R expression in healthy and diseased states. The findings lay the groundwork for clinical translation, offering potential applications in diagnosing and managing kidney-related diseases, including hypertension and other conditions involving AT1R dysregulation. en-copyright= kn-copyright= en-aut-name=ChenXinyu en-aut-sei=Chen en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraHiroyuki en-aut-sei=Kimura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasakiTakanori en-aut-sei=Sasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KlimekKonrad en-aut-sei=Klimek en-aut-mei=Konrad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=M?hligSaskia en-aut-sei=M?hlig en-aut-mei=Saskia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Arias-LozaAnahi Paula en-aut-sei=Arias-Loza en-aut-mei=Anahi Paula kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NoseNaoko en-aut-sei=Nose en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YagiYusuke en-aut-sei=Yagi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=RoweSteven P en-aut-sei=Rowe en-aut-mei=Steven P kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LapaConstantin en-aut-sei=Lapa en-aut-mei=Constantin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WernerRudolf A. en-aut-sei=Werner en-aut-mei=Rudolf A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=2 en-affil=Agency for Health, Safety and Environment, Kyoto University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Goethe University Frankfurt, University Hospital, Clinic for Radiology and Nuclear Medicine, Department of Nuclear Medicine kn-affil= affil-num=5 en-affil=Department of Nuclear Medicine and Comprehensive Heart Failure Center (DZHI), University Hospital W?rzburg kn-affil= affil-num=6 en-affil=Department of Nuclear Medicine and Comprehensive Heart Failure Center (DZHI), University Hospital W?rzburg kn-affil= affil-num=7 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Molecular Imaging and Therapeutics, Department of Radiology, School of Medicine, University of North Carolina, Chapel Hill kn-affil= affil-num=10 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=11 en-affil=Department of Nuclear Medicine, LMU Hospital, Ludwig-Maximilians-University of Munich kn-affil= affil-num=12 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=angiotensin II type 1 receptor kn-keyword=angiotensin II type 1 receptor en-keyword=organic anion transporters kn-keyword=organic anion transporters en-keyword=organic anion transporting polypeptides kn-keyword=organic anion transporting polypeptides en-keyword=renal imaging kn-keyword=renal imaging en-keyword=renin-angiotensin system kn-keyword=renin-angiotensin system END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue= article-no= start-page=114240 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of grain size and crystal orientation on tensile properties of pure titanium thin wires en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the effects of the grain size and crystal orientation on the tensile properties of pure titanium thin wires, tensile and stepwise tensile tests were conducted on pure titanium wires with diameters of approximately 180 μm and different average grain sizes (52, 37, 23, and 3.8 μm). When the grain size was large, the fracture strain was significantly smaller, the variation in tensile strength was larger, and the grain size threshold for such properties was a grain-size ratio to wire diameter of 0.13 or greater. For larger grain sizes, the slip system with the highest modified Schmid factor (MSF), which is the Schmid factor divided by the critical resolved shear stress of each slip system, was activated in all 15 grains whereas for smaller grain sizes, the percentage of slip systems activated with the highest MSF was slightly lower. In addition, the fracture location in a thin wire with larger grain sizes was highly correlated with the average MSF of the grains in the cross-section. en-copyright= kn-copyright= en-aut-name=SakamotoJunji en-aut-sei=Sakamoto en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TadaNaoya en-aut-sei=Tada en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UemoriTakeshi en-aut-sei=Uemori en-aut-mei=Takeshi 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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Tensile properties kn-keyword=Tensile properties en-keyword=Pure titanium kn-keyword=Pure titanium en-keyword=Thin wire kn-keyword=Thin wire en-keyword=Slip deformation kn-keyword=Slip deformation en-keyword=Grain size kn-keyword=Grain size en-keyword=Crystal orientation kn-keyword=Crystal orientation en-keyword=Cross-section kn-keyword=Cross-section END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Repeated Gravity Casting on the Microstructure and Mechanical Properties of 6061 Aluminum Alloy en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study systematically investigates the effects of repeated gravity casting on the microstructure and mechanical properties of 6061 aluminum alloy. With an increasing number of casting cycles from one to ten, grain coarsening and a decrease in dislocation density were observed, mainly due to the significant depletion of magnesium from 1.03 to 0.01% and titanium from 0.009 to 0.005%. These microstructural changes led to a decrease in solid-solution strengthening and grain-boundary strengthening, resulting in a 30% reduction in tensile strength, while ductility increased by about three times. Moreover, work hardening decreased with increasing the casting cycle, which can be attributed not only to the microstructural changes but also to the increase in stacking fault energy (SFE) associated with compositional evolution. From the transmission electron microscopy (TEM) observations, in the 1-cycle sample, Mg2Si precipitates were finely dispersed and a high amount of Mg element in the matrix, resulting in significant dislocation accumulation, whereas the 10-cycle sample exhibited weaker dislocation tangling. These microstructural evolutions provide insight into the degradation of mechanical performance in aluminum alloys subjected to multiple casting processes. en-copyright= kn-copyright= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakinoShouei en-aut-sei=Makino en-aut-mei=Shouei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagawaShota en-aut-sei=Nakagawa en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiShuhei en-aut-sei=Takeuchi en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShinzatoYoshifumi en-aut-sei=Shinzato en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MinodaTadashi en-aut-sei=Minoda en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhtsukaNaotaka en-aut-sei=Ohtsuka en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=3 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= affil-num=4 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=5 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= affil-num=6 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= affil-num=7 en-affil=Research & Development Center, Marketing & Technology Division, UACJ Corporation kn-affil= en-keyword=aluminum alloy kn-keyword=aluminum alloy en-keyword=repeated casting kn-keyword=repeated casting en-keyword=6061 kn-keyword=6061 en-keyword=microstructure kn-keyword=microstructure en-keyword=mechanical property kn-keyword=mechanical property END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251028 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced electric power generation in PZT ceramics via stress control en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to enhance the electric power generation of lead zirconate titanate piezoelectric (PZT) ceramics by optimizing stress distribution. Specifically, it focused on applying high stress over a broad area of the PZT ceramic to induce shape deformation in the PZT plate. Pre-straining the PZT plate into an arch shape improved voltage generation, reaching its peak at a maximum deflection of 0.04?mm due to the expanded and intensified stress distribution. However, exceeding this deflection threshold led to a decline in voltage output due to material degradation, including crack formation and 90° domain switching. Finite element analysis confirmed that the increased stress distribution in the pre-strained PZT plate contributed to higher voltage output. Additionally, electron backscatter diffraction analysis revealed that at higher pre-strains (deflection of 0.08?mm), 90°domain switching occurred, resulting in increased internal strain and potential crack formation. Experimental investigations using bulk PZT rods further demonstrated that moderate pre-straining effectively enhanced voltage output. en-copyright= kn-copyright= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimazuItsuki en-aut-sei=Shimazu en-aut-mei=Itsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= en-keyword=PZT ceramic kn-keyword=PZT ceramic en-keyword=Electric voltage kn-keyword=Electric voltage en-keyword=Piezoelectric effect kn-keyword=Piezoelectric effect en-keyword=Stress distribution kn-keyword=Stress distribution END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Upgrading Recycle Technology for Iron Removal in ADC12 Alloy Using Gravity and Magnetic Force en-subtitle= kn-subtitle= en-abstract= kn-abstract=As there is a technical issue to remove iron elements during aluminum recycling process, an attempt was made to evaluate the effectiveness of magnetic and gravitational separation methods for removing iron from Al-Si-Cu alloy (ADC12). A rare-earth samarium?cobalt (SmCo) magnet was employed during the solidification process to attract Fe-rich eutectic structures. The microstructural analysis revealed that block-like Fe-Cr-Si-based phases formed preferentially near the magnet and at the bottom of the crucible, suggesting that magnetic and gravity attraction contributed to the localized segregation of these phases. However, other Fe-based phases, including Fe-Si-based ones, are not strongly affected by magnet. Additionally, prolonged heating in the solid?liquid coexistence (SLC) region at 577 °C for 10 h led to the settling of a largely grown Fe-Cr-Si-rich crystal at the bottom of the crucible due to gravity. Other structures, such as Si-rich eutectic phases, were not influenced by gravity, which may be caused by the low density of Si compared to Fe one. From this approach, combining magnetic attraction and gravitational settling is a promising method to promote the removal of iron impurities from aluminum alloys. en-copyright= kn-copyright= en-aut-name=OkayasuM. en-aut-sei=Okayasu en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiS. en-aut-sei=Takeuchi en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SyahidM. en-aut-sei=Syahid en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkedaT. en-aut-sei=Ikeda en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Mechanical Engineering, Hasanuddin University kn-affil= affil-num=4 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= en-keyword=aluminum alloy kn-keyword=aluminum alloy en-keyword=upgrade recycle kn-keyword=upgrade recycle en-keyword=iron kn-keyword=iron en-keyword=microstructure kn-keyword=microstructure en-keyword=mechanical property kn-keyword=mechanical property END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=7 article-no= start-page=5143 end-page=5150 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250429 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electric Power Generation of PZT Piezoelectric Ceramics Using Both Direct and Inverse Piezoelectric Effects en-subtitle= kn-subtitle= en-abstract= kn-abstract=The power generation characteristics of lead zirconate titanate (PZT) piezoelectric ceramics (E-PZT) were experimentally investigated using a specialized PZT system which utilizes both the direct and inverse piezoelectric effects inherent to PZT materials. Specifically, electric voltage was generated from the vibration of E-PZT through the inverse piezoelectric effect, induced by mechanical energy transferred from the vibration of a PZT piezoelectric ceramic plate, such as a buzzer (B-PZT). In this system, an insulating material was placed between the B-PZT and E-PZT plates to address the electrical conductivity of the PZT ceramic. Various insulating materials with different thicknesses and different hardness were prepared. Additionally, the PZT systems were mounted in several distinct configurations to evaluate their power generation performance: a fully fixed around the PZT plate and a free-hanging setup. The influence of insulation materials and mounting conditions on electrical output was analyzed at various loading conditions, e.g., loading value and frequency. The results demonstrated that the generated electric voltage decreased with increasing insulation thickness and hardness, suggesting that thinner and softer insulating materials enhance output voltage. Conversely, when the PZT system was securely fixed around the PZT plate with an appropriate fixture, a higher and more stable electric voltage was generated. The voltage generated also varied by the loading condition, which is related to the strain value of the E-PZT plate, demonstrating a linear relationship between the strain and the output voltage. Notably, the strain was significantly influenced by resonant frequencies, which played a crucial role in achieving higher voltage outputs. Based on these experimental results, two power generation systems have been proposed. en-copyright= kn-copyright= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimazuItsuki en-aut-sei=Shimazu en-aut-mei=Itsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Mechanical Systems and Engineering, Okayama University kn-affil= en-keyword=PZT ceramic kn-keyword=PZT ceramic en-keyword=electric voltage kn-keyword=electric voltage en-keyword=inverse piezoelectric effect kn-keyword=inverse piezoelectric effect en-keyword=resonant frequency kn-keyword=resonant frequency END start-ver=1.4 cd-journal=joma no-vol=136 cd-vols= no-issue=10 article-no= start-page=lxaf217 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gut dysbiosis allows foodborne salmonella colonization in edible crickets: a probiotic strategy for enhanced food safety en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: Edible insects, including crickets, represent a promising protein source, yet concerns over foodborne pathogens limit consumer acceptance. This study investigated whether gut microbiota modulates colonization by Salmonella enterica subsp. enterica serovar Enteritidis (SE) in the two-spotted cricket (Gryllus bimaculatus).
Methods and Results: Under standard conditions, SE was undetectable in crickets despite prolonged exposure; however, antibiotic-induced dysbiosis enabled stable SE colonization. Long-read 16S rRNA sequencing revealed significant microbiota shifts, notably a reduction in Lactococcus garvieae. In vitro assays showed strong inhibitory effects of L. garvieae against SE, and supplementation of dysbiotic crickets with L. garvieae reduced SE colonization by ?1000-fold.
Conclusions: The native cricket gut microbiota, especially L. garvieae, plays a protective role against SE colonization. Enhancing beneficial gut bacteria could mitigate pathogen risks and promote edible insects as a sustainable protein. en-copyright= kn-copyright= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokotaKenji en-aut-sei=Yokota en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=food safety kn-keyword=food safety en-keyword=edible crickets kn-keyword=edible crickets en-keyword=Salmonella kn-keyword=Salmonella en-keyword=Lactococcus kn-keyword=Lactococcus en-keyword=probiotics kn-keyword=probiotics en-keyword=microbiome kn-keyword=microbiome END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=11 article-no= start-page=1680 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Kidney Organoids: Current Advances and Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kidney organoids, derived from stem cells, including pluripotent stem cells and adult progenitor cells, have been reported as three-dimensional in vitro models that reflect key aspects of kidney development, structure, and function. Advances in differentiation protocols and tissue engineering have enabled the generation of organoids that exhibit nephron-like structures, including glomerular and tubular structures. Kidney organoids have been widely applied in several directions, including disease modeling and therapeutic screening, drug nephrotoxicity evaluation, and regenerative medicine. In particular, kidney organoids offer a promising platform for studying genetic kidney diseases, such as polycystic kidney disease and congenital anomalies of the kidney and urinary tract (CAKUT), by allowing patient-specific modeling for the analysis of pathophysiology and therapeutic screening. Despite several current limitations, such as incomplete maturation, lack of full nephron segmentation, and variability between protocols and cell conditions, further technological innovations such as microfluidics and bioengineering may refine kidney organoid systems. This review highlights recent advances in kidney organoid research, outlines major applications, and discusses future directions to enhance their physiological relevance, functional maturity, and translational integration into preclinical and clinical nephrology. en-copyright= kn-copyright= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaraguchiSoichiro en-aut-sei=Haraguchi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=kidney organoid kn-keyword=kidney organoid en-keyword=stem cell kn-keyword=stem cell en-keyword=disease modeling kn-keyword=disease modeling en-keyword=drug toxicity kn-keyword=drug toxicity en-keyword=drug screening kn-keyword=drug screening en-keyword=regenerative medicine kn-keyword=regenerative medicine END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=9 article-no= start-page=e92587 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250917 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Intranasal Administration of Semaphorin 3A Inhibitor in a Mouse Model of Olfactory Disorder en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the effects of intranasal administration of a semaphorin 3A inhibitor (Sema3A-I) in a mouse model of olfactory disorder, where olfactory sensory neuron (OSN) axons had been severely damaged. We performed axotomy (transection of OSN axons) of the OSNs in mice and administered Sema3A?I intranasally to seven mice and saline to another seven mice. Following treatment, we assessed the thickness of the olfactory epithelium and the regeneration ratio of OSN axons. Intranasal administration of Sema3A-I did not significantly promote OSN regeneration, axonal outgrowth, or improve axonal projection compared to saline administration. Although Sema3A-I administration showed some promotion of axonal outgrowth, the difference was not statistically significant. Continuous subcutaneous administration of Sema3A-I in rats after axotomy promotes OSN regeneration and axonal outgrowth. Given that intranasal administration is minimally invasive, we believe that it may still be a feasible route when combined with additional treatment strategies. Further investigation into administration methods and therapeutic combinations is warranted. en-copyright= kn-copyright= en-aut-name=MuraiAya en-aut-sei=Murai en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NodaMinori en-aut-sei=Noda en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuAiko en-aut-sei=Shimizu en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaharaJunko en-aut-sei=Takahara en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Technical Support for Medical Science, Department of Comprehensive Technical Solutions, Okayama University kn-affil= affil-num=5 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Otolaryngology - Head and Neck Surgery, Okayama University kn-affil= en-keyword=axon growth kn-keyword=axon growth en-keyword=intranasal administration kn-keyword=intranasal administration en-keyword=olfactory disorder kn-keyword=olfactory disorder en-keyword=olfactory sensory neurons kn-keyword=olfactory sensory neurons en-keyword=semaphorin3a kn-keyword=semaphorin3a END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=6 article-no= start-page=836 end-page=849 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251028 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C1orf50 Accelerates Epithelial-Mesenchymal Transition and the Cell Cycle of Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Hepatocellular carcinoma (HCC) is a heterogeneous liver cancer with limited treatment options and a poor prognosis in advanced stages. To identify novel biomarkers and therapeutic targets, we investigated the role of chromosome 1 open reading frame 50 (C1orf50), a gene with a previously uncharacterized function in HCC.
Materials and Methods: We performed a comprehensive transcriptome data analysis of the human hepatocellular carcinoma project from The Cancer Genome Atlas (TCGA) and subsequently validated the oncogenic roles of C1orf50 using HCC cell lines.
Results: Using transcriptomic and clinical data from TCGA, we stratified 355 primary HCC samples based on C1orf50 expression levels. Patients with high C1orf50 expression exhibited significantly shorter overall survival, suggesting its association with aggressive tumor behavior. Differential expression and enrichment analyses revealed that C1orf50-high tumors were enriched in oncogenic pathways, including epithelial-mesenchymal transition (EMT), cell cycle activation, and stemness-related properties. Transcriptional regulatory network analysis detected 456 significantly dysregulated regulons, including ZEB1/2 and E2F2, key drivers of EMT and cell cycle, in the C1orf50-high group. In addition, we observed increased YAP1/TAZ signaling, further linking C1orf50 to stemness and therapeutic resistance. Functional data from CRISPR-based dependency screening suggested that several transcription factors up-regulated in the C1orf50-high state, such as ZBTB11 and CTCE, are essential for the survival of HCC cells. These findings indicate potential therapeutic vulnerabilities and support the rationale for targeting C1orf50-associated pathways.
Conclusion: C1orf50 is a novel biomarker of poor prognosis in HCC and a key regulator of oncogenic features such as EMT, cell cycle progression, and stemness. This study highlights the therapeutic potential of targeting C1orf50-related networks in aggressive subtypes of liver cancer. en-copyright= kn-copyright= en-aut-name=TANAKAATSUSHI en-aut-sei=TANAKA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OTANIYUSUKE en-aut-sei=OTANI en-aut-mei=YUSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MAEKAWAMASAKI en-aut-sei=MAEKAWA en-aut-mei=MASAKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ROGACHEVSKAYAANNA en-aut-sei=ROGACHEVSKAYA en-aut-mei=ANNA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PE?ATIRSO en-aut-sei=PE?A en-aut-mei=TIRSO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=CHINVANESSA D. en-aut-sei=CHIN en-aut-mei=VANESSA D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TOYOOKASHINICHI en-aut-sei=TOYOOKA en-aut-mei=SHINICHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ROEHRLMICHAEL H. en-aut-sei=ROEHRL en-aut-mei=MICHAEL H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FUJIMURAATSUSHI en-aut-sei=FUJIMURA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=2 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=3 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=4 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=5 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=6 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=9 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=stemness kn-keyword=stemness en-keyword=cell cycle kn-keyword=cell cycle en-keyword=epithelial?mesenchymal transition kn-keyword=epithelial?mesenchymal transition END start-ver=1.4 cd-journal=joma no-vol=130 cd-vols= no-issue=10 article-no= start-page=e2025JB032215 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical Conductivity of Carbonated Hydrous Basaltic Melt: Implications for the Conductivity Anomaly Beneath the Ocean Floors en-subtitle= kn-subtitle= en-abstract= kn-abstract=We measured the electrical conductivity of CO2 and H2O-bearing basaltic melts up to 1750 K at 2 GPa, corresponding to pressure around the lithosphere-asthenosphere boundary. The electrical conductivity of the dry and hydrous samples is comparable to those reported by previous studies on the Fe-free basaltic melt. The substantial CO2 can limit the water solubility in basaltic melt at 2 GPa. Both CO2 and H2O, which cannot completely dissolve in the melt, coexist as fluid phases, resulting in reduced electrical conductivity of the basaltic melt, which has a lower water content relative to the amount of volatile components in the bulk starting system. The activation enthalpy of basaltic melt is markedly higher than those of more evolved silicate melts, especially on the H2O-poor condition, due to the more enriched alkaline earth elements. The present results suggest that an overall melt fraction of 0.1?5.3 vol% is needed to account for the high electrical conductivity anomalies (10?1.3 to 10?0.3 S/m) beneath the oceanic plate near the East Pacific Rise and Cocos plate. However, for those regions where the electrical conductivity is extremely high (?10?0.3 S/m), more than 6 wt% H2O is expected to incorporate to maintain a melt fraction that will not trigger mechanical instability. In turn, it requires a low CO2 budget or degree of carbonation within these regions. en-copyright= kn-copyright= en-aut-name=ZhaoBin en-aut-sei=Zhao en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuJintao en-aut-sei=Zhu en-aut-mei=Jintao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HeJinze en-aut-sei=He en-aut-mei=Jinze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=electrical conductivity kn-keyword=electrical conductivity en-keyword=basaltic melts kn-keyword=basaltic melts en-keyword=oceanic floors kn-keyword=oceanic floors en-keyword=high pressure kn-keyword=high pressure END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=4 article-no= start-page=dsaf016 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250619 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reference-based chromosome-scale assembly of Japanese barley (Hordeum vulgare ssp. vulgare) cultivar Hayakiso 2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Current advances in next-generation sequencing (NGS) technology and assembling programs permit construct chromosome-level genome assemblies in various plants. In contrast to resequencing, the genome sequences provide comprehensive annotation data useful for plant genetics and breeding. Herein, we constructed a reference-based genome assembly of winter barley (H. vulgare ssp. vulgare) cv. ‘Hayakiso 2’ using long and short read NGS data and barley reference genome sequences from ‘Morex’. We constructed ‘Hayakiso 2’ genome sequences covering 4.3 Gbp with 55,477 genes. Comparative genomics revealed that 14,106 genes had orthologs to two barley data, wheat (A, B, and D homoeologs, respectively), and rice. From the gene ontology analysis, 2,494 orthologs against wheat and rice but not two barley contained agricultural important genes, such as ‘response to biotic and abiotic stress’ and ‘metabolic process’. Phylogenetic analysis using 76 pangenome data indicated that ‘Hayakiso 2’ was clustered into Japanese-type genomes with unique alleles. ‘Hayakiso 2’ genome sequences showed known genes related to flowering and facilitated barley breeding through the development of various markers related to agronomically important alleles such as tolerance to various types of biotic and abiotic stress. Therefore, ‘Hayakiso 2’ genome sequences will be used for the further barley breeding. en-copyright= kn-copyright= en-aut-name=TanakaTsuyoshi en-aut-sei=Tanaka en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaraguchiYuhi en-aut-sei=Haraguchi en-aut-mei=Yuhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodorokiTakatomo en-aut-sei=Todoroki en-aut-mei=Takatomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaishoDaisuke en-aut-sei=Saisho en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbikoTomomi en-aut-sei=Abiko en-aut-mei=Tomomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaiHiroomi en-aut-sei=Kai en-aut-mei=Hiroomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Bioinformatics Unit, Research Center for Advanced Analysis, National Agriculture and Food Research Organization kn-affil= affil-num=2 en-affil=Department of Crop Production and Breeding, Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=3 en-affil=Department of Crop Production and Breeding, Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=4 en-affil=Barley Germplasm Center, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Agroecology, Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= affil-num=6 en-affil=Department of Crop Production and Breeding, Fukuoka Agriculture and Forestry Research Center kn-affil= en-keyword=Hordeum vulgare kn-keyword=Hordeum vulgare en-keyword=genome sequencing kn-keyword=genome sequencing en-keyword=long-read sequencing kn-keyword=long-read sequencing END start-ver=1.4 cd-journal=joma no-vol=145 cd-vols= no-issue=1 article-no= start-page=457 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Component placement angles in total knee arthroplasty affect mid- to long-term clinical results: an average 8-year follow-up study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Few studies have examined how the component placement angles in total knee arthroplasty (TKA) affect mid- to long-term clinical outcomes. This study investigated the influence of coronal and sagittal plane component placement angles on mid- to long-term outcomes in mechanical alignment TKA.
Materials and Methods Forty-eight knees undergoing TKA using the FINE Total Knee System were evaluated for range of motion (ROM) preoperatively. Both ROM and clinical scores were evaluated at 3 and 5 years postoperatively and at the final follow-up (average 8-year). The valgus (alpha) and flexion (gamma) angles of the femoral component, and the varus (beta) and posterior tilt (sigma) angles of the tibial component were evaluated. Correlations between radiographic assessments, knee ROM, and clinical scores were assessed using Spearman's correlation coefficient.
Results The alpha angle was negatively correlated with the knee flexion angle (r?=?? 0.323, p?=?0.025) and ROM (r?=?? 0.352, p?=?0.014), and the sigma angle was negatively correlated with the Knee Injury and Osteoarthritis Outcome Score (KOOS)-Symptoms at 3 years postoperatively (r?=?? 0.304, p?=?0.036). The alpha angle was negatively correlated with the knee flexion angle (r?=?? 0.357, p?=?0.013), ROM (r?=?? 0.337, p?=?0.019), and KOOS-Sports and Recreation function (r?=?? 0.349, p?=?0.015), and positively correlated with the Visual Analog Scare pain score (r?=?0.307, p?=?0.034) at the final follow-up. The beta angle was positively correlated with KOOS-Pain (r?=?0.303, p?=?0.036) and KOOS-Symptoms (r?=?0.397, p?=?0.005) at the final follow-up.
Conclusions Valgus placement of the femoral component and varus placement of the tibial component in the FINE Total Knee System negatively impacted clinical scores at an average 8-year follow-up. en-copyright= kn-copyright= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoharaToshiki en-aut-sei=Kohara en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Total knee arthroplasty kn-keyword=Total knee arthroplasty en-keyword=Component placement kn-keyword=Component placement en-keyword=Varus kn-keyword=Varus en-keyword=Valgus kn-keyword=Valgus en-keyword=Clinical outcome kn-keyword=Clinical outcome 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=20251022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of flight behaviors among laboratory and field strains in Tribolium castaneum (Coleoptera: Tenebrionidae) using a simple method to measure flight ability en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most insects can fly. The acquisition of flight is a factor that allows insects to prosper on Earth. On the other hand, in the same species and population, individual differences in flight ability may occur. Flight ability can vary due to geographical conditions and cumulative rearing. Investigating these changes in flight performance is important for understanding dispersal polymorphism and the evolution of flight performance. Thus, in the present study, the flight behaviors between cumulative rearing and field strains and changes in flight behaviors between strains of the red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), which is distributed around the world were compared. Tribolium castaneum is a worldwide pest of stored grains. Its body length is about 3?4 mm. Previous studies have investigated the influence of environmental and physiological factors on the flight of this species, but no studies have examined individual differences or polymorphism in flight behaviors within this species. In this study, we developed a simple apparatus that can quantify the flight behavior of this species. The experimental apparatus was set up as a double structure with two different size containers. This apparatus was able to assess the flight activity of insects by counting individuals in a big container because insects transfer to the big container only by flight. Moreover, upward flight ability was possible to be assessed by the apparatus adding the barrier. Then, the flight behavior was compared between strains of this species that have been bred in the laboratory for more than 45 years and several strains of this species collected in the field. The results showed no variation in flight activity between strains, but flying ability was higher in strains originating from warmer regions. Here, we discussed the variations in flight behavior of T. castaneum. en-copyright= kn-copyright= en-aut-name=SoneSota en-aut-sei=Sone en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environment, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Dispersal kn-keyword=Dispersal en-keyword=Flight behavior kn-keyword=Flight behavior en-keyword=Red flour beetle kn-keyword=Red flour beetle en-keyword=Upward flight kn-keyword=Upward flight END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=e95411 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Primary Lacrimal Sac Diffuse Large B-cell Lymphoma Treated With Local Radiotherapy Alone: A Case With No Relapse After 21 Years of Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary lacrimal sac lymphoma is rare and diagnosed as diffuse large B-cell lymphoma in a predominant histopathological type. Systemic chemotherapy would be the standard of care, but local radiotherapy may be a treatment option toward a localized lesion. The present patient is a 54-year-old otherwise healthy woman with a right lacrimal sac mass, which was proven by excisional biopsy to be diffuse large B-cell lymphoma. Since she did not have any other systemic lesions on gallium scintigraphy and neck-to-abdominal computed tomography scans, which were the standard procedure at that time, she underwent local radiotherapy at 40 Gy. Two years later, at the age of 56 years, she developed radiation retinopathy with macular edema in the right eye and had spotty laser photocoagulation in the nasal half of the fundus. At the age of 57 years, she developed radiation cataract and underwent cataract surgery with intraocular lens implantation in the right eye. At the age of 58 years, the macular edema in the right eye became worse and remained active, resulting in poor visual acuity of 0.1. She thus underwent 25-gauge vitrectomy in the right eye to peel off the adhering posterior vitreous surface, together with the internal limiting membrane, as the standard procedure at that time. The visual acuity in the right eye was elevated to 0.6. She maintained the visual acuity afterward and had no relapse of lymphoma in 21 years from the diagnosis of primary right lacrimal sac diffuse large B-cell lymphoma. Local radiotherapy would still be a treatment option for localized lymphoma lesions such as primary lacrimal sac lymphoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakemotoMitsuhiro en-aut-sei=Takemoto en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Radiotherapy, Himeji Red Cross Hospital kn-affil= en-keyword=diffuse large b-cell lymphoma kn-keyword=diffuse large b-cell lymphoma en-keyword=excisional biopsy kn-keyword=excisional biopsy en-keyword=lacrimal sac kn-keyword=lacrimal sac en-keyword=laser photocoagulation kn-keyword=laser photocoagulation en-keyword=macular edema kn-keyword=macular edema en-keyword=pathology kn-keyword=pathology en-keyword=radiation cataract kn-keyword=radiation cataract en-keyword=radiation retinopathy kn-keyword=radiation retinopathy en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=vitrectomy kn-keyword=vitrectomy END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=20 article-no= start-page=10072 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurofibromin Encoded by the Neurofibromatosis Type 1 (NF1) Gene Promotes the Membrane Translocation of SPRED2, Thereby Inhibiting the ERK Pathway in Breast Cancer Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neurofibromin (NF) inhibits the RAS/RAF/ERK pathway through its interaction with SPRED1 (Sprouty-related EVH1 domain-containing protein 1). Here, we investigated the functional relationship between NF and SPRED2 in breast cancer (BC). Human BC cell lines were transfected to downregulate or overexpress NF and SPRED2 and subsequently subjected to functional assays. Protein and mRNA levels were analyzed by Western blotting and RT-qPCR, respectively. Protein?protein interactions were examined by immunoprecipitation. Database analyses and immunohistochemistry (IHC) of BC tissues were performed to validate the in vitro findings. Downregulating NF or SPRED2 expression in BC cells enhanced cell proliferation, migration and invasion accompanied by RAF/ERK activation, whereas overexpression produced opposite effects. NF formed a protein complex with SPRED2 and facilitated its translocation to the plasma membrane. By IHC, SPRED2 membrane localization was absent in NF-negative luminal A and triple-negative BC (TNBC) but present in a subset of luminal A BC. By database analyses, both NF1 and SPRED2 mRNA levels were reduced in BC tissues, and luminal A BC patients with high expression of both NF1 and SPRED2 mRNA exhibited improved relapse-free survival. These results suggest a critical role for the NF?SPRED2 axis in BC progression and highlight it as a potential therapeutic target. en-copyright= kn-copyright= en-aut-name=Su PwintNang Thee en-aut-sei=Su Pwint en-aut-mei=Nang Thee kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYuze en-aut-sei=Wang en-aut-mei=Yuze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cell Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=neurofibromatosis type 1 kn-keyword=neurofibromatosis type 1 en-keyword=neurofibromin kn-keyword=neurofibromin en-keyword=RAS/RAF/ERK kn-keyword=RAS/RAF/ERK END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=9 article-no= start-page=251152 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On weapons allometry and the form of sexual selection en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study of trait scaling with body size (allometry) has a long history, and it has been argued that positive static allometry is an indicator of directional sexual selection. However, a range of allometries exists for sexually selected traits, and modelling shows this variation can be generated by altering the form of selection (fitness functions) on the trait and/or body size. Interestingly, in all models, positive allometry appears to emerge only when there is directional selection on trait size. Here, we report on a sexually selected trait that shows strong positive static allometry and yet appears to be under stabilizing selection. This surprising finding suggests the evolution of trait scaling is even more nuanced than currently appreciated. en-copyright= kn-copyright= en-aut-name=ShinoharaHironori en-aut-sei=Shinohara en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SharmaManmohan D. en-aut-sei=Sharma en-aut-mei=Manmohan D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PennellTanya M. en-aut-sei=Pennell en-aut-mei=Tanya M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaKensuke en-aut-sei=Okada en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoskenDavid J. en-aut-sei=Hosken en-aut-mei=David J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= affil-num=2 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= affil-num=3 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Center for Ecology and Conservation, University of Exeter, Cornwall Campus kn-affil= en-keyword=inbreeding kn-keyword=inbreeding en-keyword=selection kn-keyword=selection en-keyword=beetle kn-keyword=beetle en-keyword=Gnatocerus kn-keyword=Gnatocerus END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=359 end-page=368 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Advantages of Single-Position Surgery over Posterior Fusion for Single-Level Degenerative Lumbar Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Single-position surgery with lateral lumbar interbody fusion (LLIF) and percutaneous pedicle screws (PPSs) is gaining attention for its reduced invasiveness. We developed SPAPS, a technique allowing two surgeons to perform anterior LLIF and posterior PPS insertion simultaneously in a single lateral decubitus position. This retrospective study compared SPAPS (SPAPS-LLIF, Group SL) and minimally invasive posterior/transforaminal lumbar interbody fusion (MIS-PLIF/TLIF, Group PT) in patients treated between 2016 and 2019 with a two-year follow-up. Operative time, estimated blood loss (EBL), length of hospital stay (LOS), JOABPEQ and VAS scores, segmental lordotic angle, lumbar lordotic angle, segmental Cobb’s angle, PPS misplacement, PPS loosening, fusion status, and muscle cross-sectional areas were compared. Fifty-two patients were analyzed (Group SL: 25; Group PT: 27). SPAPS significantly reduced operative time (118.0 vs. 165.3 min, p <0.01) and estimated blood loss (8.6 vs. 164.1 mL, p<0.01). While clinical outcomes and hospital stay were comparable, Group SL had significantly lower PPS loosening (0% vs. 13%, p<0.01) and non-union rates (0% vs. 22.2%, p=0.02). Multifidus muscle atrophy was also less in Group SL (?14.3 vs. ?121.5 mm2, p<0.01). SPAPS demonstrated advantages in reducing surgical invasiveness without compromising clinical efficacy, offering a promising alternative to conventional posterior fusion surgery. en-copyright= kn-copyright= en-aut-name=HiroseTomohiko en-aut-sei=Hirose en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkumaHisanori en-aut-sei=Ikuma en-aut-mei=Hisanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaKazutoshi en-aut-sei=Otsuka en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawasakiKeisuke en-aut-sei=Kawasaki en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Otsuka Orthopedic Clinic kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= en-keyword=single-position surgery kn-keyword=single-position surgery en-keyword=simultaneous kn-keyword=simultaneous en-keyword=lateral decubitus positioning kn-keyword=lateral decubitus positioning en-keyword=lateral lumbar interbody fusion kn-keyword=lateral lumbar interbody fusion en-keyword=posterior lumbar interbody fusion kn-keyword=posterior lumbar interbody fusion END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=329 end-page=337 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current Status of Extracorporeal Membrane Oxygenation as a Treatment Strategy for Primary Graft Dysfunction after Lung Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary graft dysfunction (PGD) is one of the major risk factors affecting patients’ short- and long-term survival after lung transplantation. No particular management strategy has been established for PGD; supportive care is the mainstay of PGD treatment. When a supportive strategy fails, the patient may require the introduction of extracorporeal membrane oxygenation (ECMO) as the last-resort measure for severe PGD. A variety of study of ECMO as a PGD treatment was reported and the management of PGD patients developed so far. Early recognition of a patient’s need for ECMO and its prompt initiation are critical to improved outcomes. The use of venovenous-ECMO became the preferred procedure for PGD rather than venoarterial-ECMO. However, the current ECMO strategy has limitations, and using ECMO to manage patients with PGD is not sufficiently effective. Further studies are required to develop this promising technology. en-copyright= kn-copyright= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=primary graft dysfunction kn-keyword=primary graft dysfunction en-keyword=extracorporeal membrane oxygenation kn-keyword=extracorporeal membrane oxygenation en-keyword=ex vivo lung perfusion kn-keyword=ex vivo lung perfusion END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=417 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Guided Self-Study Platform of Integrating Documentation, Code, Visual Output, and Exercise for Flutter Cross-Platform Mobile Programming en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, Flutter with the Dart programming language has become widely popular in mobile developments, allowing developers to build multi-platform applications using one codebase. An increasing number of companies are adopting these technologies to create scalable and maintainable mobile applications. Despite this increasing relevance, university curricula often lack structured resources for Flutter/Dart, limiting opportunities for students to learn it in academic environments. To address this gap, we previously developed the Flutter Programming Learning Assistance System (FPLAS), which supports self-learning through interactive problems focused on code comprehension through code-based exercises and visual interfaces. However, it was observed that many students completed the exercises without fully understanding even basic concepts, if they already had some knowledge of object-oriented programming (OOP). As a result, they may not be able to design and implement Flutter/Dart codes independently, highlighting a mismatch between the system’s outcomes and intended learning goals. In this paper, we propose a guided self-study approach of integrating documentation, code, visual output, and exercise in FPLAS. Two existing problem types, namely, Grammar Understanding Problems (GUP) and Element Fill-in-Blank Problems (EFP), are combined together with documentation, code, and output into a new format called Integrated Introductory Problems (INTs). For evaluations, we generated 16 INT instances and conducted two rounds of evaluations. The first round with 23 master students in Okayama University, Japan, showed high correct answer rates but low usability ratings. After revising the documentation and the system design, the second round with 25 fourth-year undergraduate students in the same university demonstrated high usability and consistent performances, which confirms the effectiveness of the proposal. en-copyright= kn-copyright= en-aut-name=KinariSafira Adine en-aut-sei=Kinari en-aut-mei=Safira Adine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=Flutter kn-keyword=Flutter en-keyword=Dart kn-keyword=Dart en-keyword=cross-platform kn-keyword=cross-platform en-keyword=self-learning kn-keyword=self-learning en-keyword=introductory kn-keyword=introductory END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=3 article-no= start-page=52 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Extension of Input Setup Assistance Service Using Generative AI to Unlearned Sensors for the SEMAR IoT Application Server Platform en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, Internet of Things (IoT) application systems are broadly applied to various sectors of society for efficient management by monitoring environments using sensors, analyzing sampled data, and giving proper feedback. For their fast deployment, we have developed Smart Environmental Monitoring and Analysis in Real Time (SEMAR) as an integrated IoT application server platform and implemented the input setup assistance service using prompt engineering and a generative AI model to assist connecting sensors to SEMAR with step-by-step guidance. However, the current service cannot assist in connections of the sensors not learned by the AI model, such as newly released ones. To address this issue, in this paper, we propose an extension to the service for handling unlearned sensors by utilizing datasheets with four steps: (1) users input a PDF datasheet containing information about the sensor, (2) key specifications are extracted from the datasheet and structured into markdown format using a generative AI, (3) this data is saved to a vector database using chunking and embedding methods, and (4) the data is used in Retrieval-Augmented Generation (RAG) to provide additional context when guiding users through sensor setup. Our evaluation with five generative AI models shows that OpenAI’s GPT-4o achieves the highest accuracy in extracting specifications from PDF datasheets and the best answer relevancy (0.987), while Gemini 2.0 Flash delivers the most balanced results, with the highest overall RAGAs score (0.76). Other models produced competitive but mixed outcomes, averaging 0.74 across metrics. The step-by-step guidance function achieved a task success rate above 80%.

To support novice students’ self-study, in this paper, we propose a novel exercise format called the phrase fill-in-blank problem (PFP) in the Web Programming Learning Assistant System (WPLAS). A PFP instance presents a source code with blanked phrases (a set of elements) and corresponding Web page screenshots. Then, it requests the user to fill in the blanks, and the answers are automatically evaluated through string matching with predefined correct answers. By increasing blanks, PFP can come close to writing a code from scratch. To facilitate scalable and context-aware question creation, we implemented the PFP instance generation algorithm in Python using regular expressions. This approach targets meaningful code segments in HTML, CSS, and JavaScript that reflect the interactive behavior of front-end development. For evaluations, we generated 10 PFP instances for basic Web programming topics and 5 instances for video games and assigned them to students at Okayama University, Japan, and the State Polytechnic of Malang, Indonesia. Their solution results show that most students could solve them correctly, indicating the effectiveness and accessibility of the generated instances. In addition, we investigated the ability of generative AI, specifically ChatGPT, to solve the PFP instances. The results show 86.7% accuracy for basic-topic PFP instances. Although it still cannot fully find answers, we must monitor progress carefully. In future work, we will enhance PFP in WPLAS to handle non-unique answers by improving answer validation for flexible recognition of equivalent responses. en-copyright= kn-copyright= en-aut-name=QiHuiyu en-aut-sei=Qi en-aut-mei=Huiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiZhikang en-aut-sei=Li en-aut-mei=Zhikang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Sandi KyawHtoo Htoo en-aut-sei=Sandi Kyaw en-aut-mei=Htoo Htoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KaoWen Chung en-aut-sei=Kao en-aut-mei=Wen Chung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=Web client programming kn-keyword=Web client programming en-keyword=Web game kn-keyword=Web game en-keyword=HTML kn-keyword=HTML en-keyword=CSS kn-keyword=CSS en-keyword=JavaScript kn-keyword=JavaScript en-keyword=phrase fill-in-blank problem kn-keyword=phrase fill-in-blank problem en-keyword=regular expression kn-keyword=regular expression en-keyword=generative AI kn-keyword=generative AI END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=7 article-no= start-page=607 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Fundamental Statistics Self-Learning Method with Python Programming for Data Science Implementations en-subtitle= kn-subtitle= en-abstract= kn-abstract=The increasing demand for data-driven decision making to maintain the innovations and competitiveness of organizations highlights the need for data science educations across academia and industry. At its core is a solid understanding of statistics, which is necessary for conducting a thorough analysis of data and deriving valuable insights. Unfortunately, conventional statistics learning often lacks practice in real-world applications using computer programs, causing a separation between conceptual knowledge of statistics equations and their hands-on skills. Integrating statistics learning into Python programming can convey an effective solution for this problem, where it has become essential in data science implementations, with extensive and versatile libraries. In this paper, we present a self-learning method for fundamental statistics through Python programming for data science studies. Unlike conventional approaches, our method integrates three types of interactive problems?element fill-in-blank problem (EFP), grammar-concept understanding problem (GUP), and value trace problem (VTP)?in the Programming Learning Assistant System (PLAS). This combination allows students to write code, understand concepts, and trace the output value while obtaining instant feedback so that they can improve retention, knowledge, and practical skills in learning statistics using Python programming. For evaluations, we generated 22 instances using source codes for fundamental statistics topics, and assigned them to 40 first-year undergraduate students at UPN Veteran Jawa Timur, Indonesia. Statistics analytical methods were utilized to analyze the student learning performances. The results show that a significant correlation (?<0.05) exists between the students who solved our proposal and those who did not. The results confirm that it can effectively assist students in learning fundamental statistics self-learning using Python programming for data science implementations. en-copyright= kn-copyright= en-aut-name=RiyantokoPrismahardi Aji en-aut-sei=Riyantoko en-aut-mei=Prismahardi Aji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DamalianaAviolla Terza en-aut-sei=Damaliana en-aut-mei=Aviolla Terza kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PrasetyaDwi Arman en-aut-sei=Prasetya en-aut-mei=Dwi Arman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Data Science, Universitas Pembangunan Nasional Veteran Jawa Timur kn-affil= affil-num=6 en-affil=Department of Data Science, Universitas Pembangunan Nasional Veteran Jawa Timur kn-affil= en-keyword=fundamental statistics kn-keyword=fundamental statistics en-keyword=self-learning method kn-keyword=self-learning method en-keyword=Python programming kn-keyword=Python programming en-keyword=data science kn-keyword=data science END
