Twenty-one first-year students completed nine Write & Improve (W&I) tasks, progressing from descriptive to argumentative essays. Each task was revised following W&I feedback, and students were asked to write a short reflective log. An explanatory mixed-methods approach was adopted, combining quantitative analyses of writing performance and linguistic features with qualitative coding of students' reflections. Findings showed measurable gains in both higher- and lower-level groups, with particularly notable improvement among lower-level students in complexity, fluency, and sophistication. While the higher group consistently outperformed the lower group in Term 1, this gap narrowed in Term 2. Reflection logs provided important insights into feedback literacy: students initially valued W&I for surface-level corrections but later expressed frustration as tasks became more complex and scores plateaued. This tendency was especially evident among lower-level students, reflecting both the affordances and limitations of automated feedback. The study concludes that AI-assisted tools can foster writing development and emerging feedback literacy, but sustained progress requires teacher mediation. Integrating Automated Writing Evaluation (AWE) into ecological feedback environments - combining AI, teacher, and student reflection - offers a promising approach for sustainable L2 writing instruction. en-copyright= kn-copyright= en-aut-name=OtoshiJunko en-aut-sei=Otoshi en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujishimaNaomi en-aut-sei=Fujishima en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Kawasaki Medical School kn-affil= en-keyword=EFL writing kn-keyword=EFL writing en-keyword=AI-assisted tools kn-keyword=AI-assisted tools en-keyword=feedback literacy kn-keyword=feedback literacy en-keyword=ecological environments kn-keyword=ecological environments en-keyword=Write & Improve kn-keyword=Write & Improve END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=6 article-no= start-page=e110548 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathway Enrichment Analysis of Whole-Exome Sequencing Data from Formalin-Fixed, Paraffin-Embedded Enucleated Eyes with Retinoblastoma and Choroidal Malignant Melanoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Intraocular tumors are extremely rare, small in size, and difficult to approach by biopsy. In the era of cancer genome analysis, we designed a pilot study to perform whole-exome sequencing of formalin-fixed paraffin-embedded enucleated eyes of retinoblastoma and choroidal malignant melanoma as two major intraocular malignancies.
Methodology: Genomic DNA was isolated from intraocular tumor areas of 105 paraffin sections with a 5 μm thickness of seven enucleated eyes with retinoblastoma and seven eyes with choroidal malignant melanoma. One of 7 samples of retinoblastoma and another of seven samples of choroidal malignant melanoma were excluded from the study since the sequencing output and depth of reads were lower compared with the other samples. The sequencing data after quality control were aligned to the reference genome sequence (hg38, GRCh38 Assembly, Genome Reference Consortium Human Build 38), and the mapped reads were processed to improve data quality. Somatic mutations (single nucleotide variants, insertions and deletions, and multiple nucleotide variants) in each sample were extracted after excluding variants reported in a Panel of Normals (PON) from the 1000 Genomes Project. Additional selection criteria included a mutation depth of ?5 reads and either no registration in or an allele frequency of less than 5% in the Tohoku Medical Megabank of Japan (ToMMo 60KJPN-SNV/INDEL Allele Frequency Panel).
Results: Candidate genes with somatic mutations were selected by three criteria: genes with the same mutation shared by two samples or more, recurrently mutated genes three times or over, and genes of driver candidates identified in combining several different driver mutation-detecting programs by Integrative OncoGenomics (IntOGen). Using candidate genes detected by any of the three criteria as input, enrichment analyses identified 28 pathways in Gene Ontology (GO) and 2 pathways in the Kyoto Encyclopedia of Genes and Genomes (KEGG) for retinoblastoma, while 385 pathways in GO, 12 in KEGG, 2 in the Hallmark gene set of the Molecular Signatures Database (MSigDB), and 47 in Reactome were identified for choroidal malignant melanoma. The enrichment maps showed three major pathways differently in retinoblastoma and choroidal malignant melanoma: one with dynein in retinoblastoma and another with MET in choroidal malignant melanoma.
Conclusions: Although there were limitations related to the small amounts of DNA available from formalin-fixed, paraffin-embedded small-sized tissues and the absence of matched normal control tissue, whole-exome sequencing provided clues to somatic mutations that were enriched in specific pathways and differed between retinoblastoma and choroidal malignant melanoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoAkira en-aut-sei=Saito en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AmemiyaMitsuhiro en-aut-sei=Amemiya en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamitsujiShigeo en-aut-sei=Kamitsuji en-aut-mei=Shigeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Medical Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Genomic Statistics, Stagen Co.

Macroceras en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hybridization can hinder or promote diversification, and growing genomic evidence suggests that it can facilitate adaptation and speciation. Despite recent progress, however, the quantitative contribution and temporal scope of hybridization to diversification remain poorly understood. The genus Epimedium is a recently diverged lineage, and sect. Macroceras largely consists of endemic species in Japan that are distributed across diverse environments, including limestone, serpentine, coastal habitats, heavy-snow regions, and regions with mild winters. Although natural hybridization and hybrid species have been reported in this section, molecular evidence demonstrating the contribution of hybridization to lineage diversification is limited. We reconstructed phylogenetic relationships using genome-wide single-nucleotide polymorphism (SNP) data from Epimedium sect. Macroceras and tested for genomic signatures consistent with hybridization. Phylogenetic analyses suggest that E. koreanum from Korea is sister to Japanese Epimedium lineages, consistent with an initial colonization of Japan from the Korean Peninsula. The analyses also revealed complex relationships among Japanese species and frequent signals of historical interspecific introgression. Our results are consistent with a history of recent diversification in sect. Macroceras accompanied by introgressive hybridization, which may have contributed to diversification across heterogeneous environments in Japan. This study provides the first genome-wide insights into the evolutionary history of Epimedium sect. Macroceras and reveals complex reticulate relationships among the lineages. en-copyright= kn-copyright= en-aut-name=KusatakeEmi en-aut-sei=Kusatake en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonishiMomoka en-aut-sei=Konishi en-aut-mei=Momoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomokuniShuto en-aut-sei=Tomokuni en-aut-mei=Shuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanagiYosuke en-aut-sei=Yanagi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KariyamaShungo en-aut-sei=Kariyama en-aut-mei=Shungo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItohTakehito en-aut-sei=Itoh en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyodaAtsushi en-aut-sei=Toyoda en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KimSeung-Chul en-aut-sei=Kim en-aut-mei=Seung-Chul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MimuraMakiko en-aut-sei=Mimura en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Biology, Okayama University kn-affil= affil-num=2 en-affil=Department of Biology, Okayama University kn-affil= affil-num=3 en-affil=Department of Biology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biology, Okayama University kn-affil= affil-num=5 en-affil=Society of Kurashiki Museum of Natural History kn-affil= affil-num=6 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Department of Genomics and Evolutionary Biology, National Institute of Genetics kn-affil= affil-num=8 en-affil=Department of Biological Sciences, Sungkyunkwan University kn-affil= affil-num=9 en-affil=Department of Biology, Okayama University kn-affil= en-keyword=Phylogenomics kn-keyword=Phylogenomics en-keyword=Introgression kn-keyword=Introgression en-keyword=Evolutionary radiation kn-keyword=Evolutionary radiation en-keyword=Pleistocene kn-keyword=Pleistocene en-keyword=Ecological divergence kn-keyword=Ecological divergence en-keyword=Reticulate evolution kn-keyword=Reticulate evolution END start-ver=1.4 cd-journal=joma no-vol=408 cd-vols= no-issue= article-no= start-page=117978 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A flexible PVDF-based galloping flow sensor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective monitoring of low flow velocities in small rivers and irrigation channels is hindered by the power requirements and maintenance costs of existing technologies. This study proposes a novel flexible piezoelectric polymer flow sensor utilizing galloping vibration to detect flow velocity in the low range (? 0.1?m/s). The sensor features a flexible cantilever structure composed of a silicone rubber beam embedded with a polyvinylidene fluoride (PVDF) film and a tip pillar. Unlike conventional devices based on flow-induced vibration, the use of low-stiffness materials enables the induction of self-excited vibration even under weak fluid forces. Computational fluid dynamics (CFD) analysis has been conducted to optimize the tip shape; a D-shaped semicylinder is selected over a cylinder and a square prism because the geometry maximizes the lift force per unit mass, ensuring efficient energy conversion. To predict sensor behavior, a coupled mechanical-fluid-electrical model was developed. Specifically, the model accounts for the static deflection angle caused by fluid drag. Water channel experiments demonstrated that sensors with beam thicknesses under 4?mm successfully generated stable periodic outputs at 0.1?m/s, a regime previously difficult for galloping-based devices. Conversely, thicker beam which has a thickness of 8?mm achieved higher outputs at higher velocities but failed to actuate at low speeds. Furthermore, the study showed a vibration suppression phenomenon in flexible beams at high flow velocities due to excessive static deflection, which was accurately reproduced by the analytical model. These findings establish structural stiffness as the critical design parameter for optimizing the operable velocity range of flow sensors. en-copyright= kn-copyright= en-aut-name=KuroseMitsuki en-aut-sei=Kurose en-aut-mei=Mitsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaTakefumi en-aut-sei=Kanda en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoYuya en-aut-sei=Sato en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakimotoShuichi en-aut-sei=Wakimoto en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiDaisuke en-aut-sei=Yamaguchi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiejimaShinji en-aut-sei=Hiejima en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UedaTakeji en-aut-sei=Ueda en-aut-mei=Takeji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Hydro-VENUS Co., Ltd., Okayama University kn-affil= en-keyword=Flow velocity sensor kn-keyword=Flow velocity sensor en-keyword=Piezoelectric polymer kn-keyword=Piezoelectric polymer en-keyword=Flow induced vibration kn-keyword=Flow induced vibration en-keyword=Galloping vibration kn-keyword=Galloping vibration END start-ver=1.4 cd-journal=joma no-vol=408 cd-vols= no-issue= article-no= start-page=117938 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tip position estimation of a 3-DOF soft mechanism using artificial muscles with optical fibers en-subtitle= kn-subtitle= en-abstract= kn-abstract=McKibben-type pneumatic artificial muscles (PAMs) are lightweight and flexible soft actuators with a high power-to-weight ratio, and have been widely applied to rehabilitation devices, power-assist systems, and soft robotic mechanisms. By integrating sensing functions into PAMs, their usability and controllability can be enhanced, enabling the development of more practical and advanced soft mechanisms. We previously proposed a smart artificial muscle (SAM) by integrating an optical fiber into the braided sleeve of a McKibben-type PAM, which enables displacement estimation by measuring optical bending loss. The SAM is compatible with conventional PAM fabrication processes; however, the sensor output exhibits strong nonlinearity and time dependency. In this study, an LSTM-based state estimation framework is extended from a single SAM to a three-degree-of-freedom soft mechanism composed of multiple SAMs, where strong nonlinear coupling and mutual interference arise among actuators. In the proposed framework, the LSTM model jointly processes time-series data of multi-channel optical sensor outputs and applied pressures of the three SAMs, along with past estimated states as inputs. This structure enables the model to capture nonlinear coupling, hysteresis, and time-dependent behavior, allowing estimation of the tip position of the soft mechanism. Experimental results demonstrate that the proposed method accurately captures complex nonlinear dynamics and mutual mechanical interference among multiple SAMs, achieving accurate tip position estimation. These results indicate that SAMs with integrated sensing and actuation capabilities, combined with machine-learning-based estimation, provide an effective approach for state estimation of multi-DOF soft robotic mechanisms. en-copyright= kn-copyright= en-aut-name=OkadaRikimaru en-aut-sei=Okada en-aut-mei=Rikimaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakimotoShuichi en-aut-sei=Wakimoto en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaYuichiro en-aut-sei=Toda en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiuraShun en-aut-sei=Miura en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiDaisuke en-aut-sei=Yamaguchi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaTakefumi en-aut-sei=Kanda en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Pneumatic artificial muscle kn-keyword=Pneumatic artificial muscle en-keyword=Smart artificial muscle kn-keyword=Smart artificial muscle en-keyword=Soft mechanism kn-keyword=Soft mechanism en-keyword=State estimation kn-keyword=State estimation en-keyword=Long short-term memory kn-keyword=Long short-term memory END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=26007 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Understory Vegetation Structure in Remnant Natural Forests and Acacia Plantations on Coastal Sand Dunes in North Central Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the coastal sand dune forests of North Central Vietnam, vegetation has been seriously damaged by war and overexploitation. To recover ecosystem functions, including sand stabilisation under harsh environments, exotic species like Acacia spp. have been planted as a monoculture. However, the long-term sustainability of this practice remains unclear. To assess the long-term effectiveness of revegetation with Acacia spp., this study aims to understand the differences and similarities in ecological characteristics of remnant natural forests and Acacia plantations on the coastal sand dune of North Central Vietnam by comparing understory vegetation structure and environmental conditions. We investigated the understory vegetation (height < 130 cm) in a total of 54 quadrants (1 m × 1 m), including nine natural forests and nine Acacia plantations. We compared diversity indices by mixed ANOVA and examined the differences in the understory vegetation structure between the two forest types through PERMANOVA. We also determined some abiotic environmental factors (e.g. light and soil water availability, and soil pH). We identified 951 individuals, with 792 found in natural forests and 159 in plantations. The species found in natural forests were well-distributed among Liana phanerophytes (Lp), Microphanerophytes (Mi), Mega-Mesophanerophytes (MM), and Cryptophytes (Cr). In contrast, species found in plantations were predominantly Cr, Hemicryptophytes (Hm), and MM. All diversity indices were significantly higher in natural forests (P < 0.05), and the NMDS analysis confirmed significant differences in the understory vegetation structure between natural forests and plantations. Only soil pH was significantly lower in natural forests (P < 0.05), while none of the environmental factors had a statistically significant impact on the variations in understory vegetation structure. Our results indicate that succession by native tree species does not seem to occur naturally in Acacia plantations. Hence, to restore and sustainably develop coastal sand dune forests in North Central Vietnam, it is essential to establish a scientifically based strategy for managing and protecting the remaining natural remnant forest areas. en-copyright= kn-copyright= en-aut-name=DoanTuan Quoc en-aut-sei=Doan en-aut-mei=Tuan Quoc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoTetsuya K. en-aut-sei=Matsumoto en-aut-mei=Tetsuya K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DinhTai Tien en-aut-sei=Dinh en-aut-mei=Tai Tien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeHung Thai en-aut-sei=Le en-aut-mei=Hung Thai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoTuan Ngoc Anh en-aut-sei=Ho en-aut-mei=Tuan Ngoc Anh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MikiNaoko H. en-aut-sei=Miki en-aut-mei=Naoko H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoHoang Thai Dac en-aut-sei=Ho en-aut-mei=Hoang Thai Dac kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirobeMuneto en-aut-sei=Hirobe en-aut-mei=Muneto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Ibaraki University, Graduate School of Science and Engineering kn-affil= affil-num=3 en-affil=Hue Union of Science and Technology Associations (HUSTA) kn-affil= affil-num=4 en-affil=Hue University, University of Agriculture and Forestry kn-affil= affil-num=5 en-affil=Hue Union of Science and Technology Associations (HUSTA) kn-affil= affil-num=6 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=7 en-affil=Hue Union of Science and Technology Associations (HUSTA) kn-affil= affil-num=8 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= en-keyword=natural forest kn-keyword=natural forest en-keyword=Acacia plantation kn-keyword=Acacia plantation en-keyword=coastal sand dunes forest kn-keyword=coastal sand dunes forest en-keyword=diversity kn-keyword=diversity en-keyword=understory vegetation kn-keyword=understory vegetation en-keyword=life forms kn-keyword=life forms en-keyword=environmental factor kn-keyword=environmental factor END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Uniqueness of Dirichlet forms for random point fields in the absence of tail triviality en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider an infinite system of interacting Brownian motions that preserves a given random point field invariant. Such dynamics are constructed using Dirichlet form theory, which naturally leads to two Dirichlet forms for the random point field: the upper and the lower Dirichlet forms. A fundamental question is the uniqueness of the Dirichlet form: that is, whether these two forms coincide. This uniqueness has often been imposed as a key assumption in the Dirichlet form approach to the stochastic analysis for infinite particle systems. A sufficient condition for the uniqueness of the Dirichlet forms is known when the random point field is tail trivial. However, tail triviality has been established for only a limited class of random point fields. In this paper, we prove the uniqueness of the Dirichlet form without assuming tail triviality. The main contribution of this work is to establish the tail preserving property, which asserts that global properties of the system, such as particle density, are preserved under time evolution. As a consequence, our results also imply the strong uniqueness of solutions to the associated infinite-dimensional stochastic differential equations. en-copyright= kn-copyright= en-aut-name=KawamotoYosuke en-aut-sei=Kawamoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama university kn-affil= en-keyword=Infinite particle systems kn-keyword=Infinite particle systems en-keyword=Interacting Brownian motions kn-keyword=Interacting Brownian motions en-keyword=Uniqueness of Dirichlet forms kn-keyword=Uniqueness of Dirichlet forms en-keyword=Random matrices kn-keyword=Random matrices END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=94 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three-dimensional virtual planning reduces operative time in orthognathic surgery: a procedure-specific retrospective study incorporating additive manufacturing en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Three-dimensional virtual surgical planning (3D-VSP) is increasingly used in orthognathic surgery; however, procedure-specific evidence regarding its real-world impact on operative efficiency and intraoperative blood loss remains limited. This study evaluated the association between 3D-VSP implementation and operative time, and intraoperative blood loss across different orthognathic procedures.
Methods This retrospective cohort study included consecutive patients who underwent orthognathic surgery at a single academic institution before (2019?2020) and after (2023?2024) the full implementation of 3D-VSP integrated with in-house additive manufacturing (n?=?344). Procedure-specific multivariable linear regression analyses were performed, adjusting for age, sex, and surgeon experience.
Results After 3D-VSP implementation, operative time was reduced by approximately 36 min in sagittal split ramus osteotomy (SSRO), 50 min in Le Fort I (LF1) combined with SSRO, and 42 min in segmental LF1 combined with SSRO, representing a 15?20% reduction in total operative time. No meaningful reduction was observed in intraoral vertical ramus osteotomy (IVRO)-based procedures. A statistically significant, but modest, reduction in intraoperative blood loss was observed only in SSRO. The time-saving effect was independent of surgeon experience.
Conclusion The clinical benefit of 3D-VSP in orthognathic surgery is procedure-dependent and most evident in geometrically complex SSRO-based operations. These findings support the targeted implementation of digital planning and additive manufacturing workflows to improve operative efficiency in routine practice. en-copyright= kn-copyright= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaNorie en-aut-sei=Yoshioka en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyamaAkiyoshi en-aut-sei=Nishiyama en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasuiMasanori en-aut-sei=Masui en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KadoyaKoichi en-aut-sei=Kadoya en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakakuraHiroaki en-aut-sei=Takakura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ObataKyoichi en-aut-sei=Obata en-aut-mei=Kyoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OnoKisho en-aut-sei=Ono en-aut-mei=Kisho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UmemoriKoki en-aut-sei=Umemori en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Orthognathic surgery kn-keyword=Orthognathic surgery en-keyword=Surgical planning kn-keyword=Surgical planning en-keyword=Three-dimensional virtual surgical planning kn-keyword=Three-dimensional virtual surgical planning en-keyword=Operative time kn-keyword=Operative time en-keyword=Intraoperative blood loss kn-keyword=Intraoperative blood loss en-keyword=Additive manufacturing kn-keyword=Additive manufacturing en-keyword=Sagittal split ramus osteotomy kn-keyword=Sagittal split ramus osteotomy END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5 article-no= start-page=255 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260420 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=HLA-matched versus haploidentical donor transplantation with post-transplant cyclophosphamide: a study on behalf of the donor/source working group of the Japanese society for transplantation and cellular therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-transplant cyclophosphamide (PTCy) is now being increasingly applied to HLA-matched donor (MD) transplantation. Prior studies in Western countries have demonstrated that allogeneic hematopoietic cell transplantation (allo-HCT) employing PTCy yields better outcomes with HLA-matched donors (MDs) than with haploidentical donors (HIDs). However, the effect of HLA mismatch may differ among racial groups. We retrospectively analyzed adult patients with hematological malignancies who underwent their first allo-HCT with PTCy from MDs or HIDs registered to the Japanese registry database between 2013 and 2021. Among 63 (related, n?=?33; unrelated, n?=?30) and 1261 patients who received MD and HID allo-HCT with PTCy, 50 (related, n?=?30; unrelated, n?=?20) and 100 patients were assigned to MD and HID groups by 1:2 propensity score matching (PSM). The results showed that MD recipients had better neutrophil recovery (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.04?2.10; P?=?0.031) and lower risk of non-relapse mortality (NRM) (HR, 0.19; 95% CI, 0.05?0.81; P?=?0.024) than HID recipients. Multivariable analyses in the entire cohort before PSM confirmed these findings. Fatal infection was the primary cause of NRM in the HID group. This study is the first to demonstrate that, within a homogeneous Asian cohort, MD may have an advantage over HID in PTCy-based allo-HCT in facilitating neutrophil engraftment and reducing the risk of NRM. en-copyright= kn-copyright= en-aut-name=NakayaYosuke en-aut-sei=Nakaya en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamaeHirohisa en-aut-sei=Nakamae

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

kn-abstract=Molecules featuring both sulfur and nitrogen atoms are privileged scaffolds in medicinal chemistry and biological systems. However, methods for the direct and regioselective installation of these heteroatoms onto alkenes remain limited. Herein, we report a visible-light-induced, three-component sulfanyloximation of styrenes utilizing thiols and N-nitrosamine as a bench-stable nitrogen oxide (NO) surrogate. This regioselective protocol operates under mild conditions with remarkable functional group tolerance. The synthetic utility of this methodology is further demonstrated by its extension to the synthesis of 2,3-disubstituted indoles and the divergent downstream derivatization of α-sulfanyl ketoxime products via imidoyl fluoride intermediates. An extensive mechanistic investigation supports a pathway initiated by thiyl radical addition to alkenes followed by radical coupling with in situ generated NO. en-copyright= kn-copyright= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TamuraToshiki en-aut-sei=Tamura en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkimotoShuta en-aut-sei=Akimoto en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiuraTomoya en-aut-sei=Miura en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Peripheral Odontogenic Myxofibroma Arising in the Palatal Gingiva of the Maxillary Second Premolar Region: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Odontogenic myxofibroma (OMF) is a rare benign mesenchymal odontogenic tumor characterized by myxoid stroma with a prominent fibrous component. Although it usually arises intraosseously within the jaws, the peripheral variant, peripheral odontogenic myxofibroma (POMF), which occurs in extraosseous soft tissues, is uncommon and may be clinically misdiagnosed as a reactive gingival lesion. We report a case of POMF in a 68-year-old man who was referred for evaluation of a painless, slowly enlarging swelling of the palatal gingiva in the left maxillary second premolar region, which had initially been diagnosed as chronic periodontitis at a local clinic. An intraoral examination revealed an elastic, firm mass with partial erythema on the palatal marginal gingiva. Panoramic radiography showed mild generalized horizontal bone loss without lesion-specific changes, and computed tomography revealed no bone resorption associated with the lesion. Exfoliative cytology was negative for intraepithelial lesions or malignancy. The lesion was excised with a 5-mm clinical margin, including periosteum, and superficial peripheral ostectomy of the adjacent cortical bone was performed. Histopathological examination revealed a myxoid stroma rich in mucinous matrix and collagen fibers, containing sparsely distributed spindle-shaped cells and scattered nests of odontogenic epithelium. Alcian blue staining revealed diffuse positivity, supporting the diagnosis of POMF. No recurrence was observed during a 2-year follow-up period. This case highlights a diagnostic pitfall in the tooth-bearing gingiva and underscores the importance of histopathological confirmation of persistent gingival masses. When imaging shows no apparent bone involvement, and clinical suspicion of malignancy is low, complete excision with an adequate soft-tissue margin and selective, limited bone removal may achieve local control while preserving the adjacent teeth; long-term follow-up remains advisable. en-copyright= kn-copyright= en-aut-name=MasuiMasanori en-aut-sei=Masui en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YutoriHirokazu en-aut-sei=Yutori en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimuraAi en-aut-sei=Fujimura en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery , Faculty of Medicine , Dentistry and Pharmaceutical Sciences Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery , Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery , Kagawa Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery , Faculty of Medicine , Dentistry and Pharmaceutical Sciences Okayama University kn-affil= en-keyword=case report kn-keyword=case report en-keyword=excisional biopsy kn-keyword=excisional biopsy en-keyword=palatal gingiva kn-keyword=palatal gingiva en-keyword=peripheral odontogenic myxofibroma kn-keyword=peripheral odontogenic myxofibroma en-keyword=peripheral odontogenic myxoma kn-keyword=peripheral odontogenic myxoma END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proposing an alternative direction for the development of research: a complementary perspective on Schoenfeld’s approach to generality en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to propose a theoretical framework that suggests directions for future research. While Schoenfeld’s three-axis heuristic framework is well known for this purpose, it primarily points toward increasing generality. Drawing on prior studies on the generalizability of empirical findings in educational research, this paper argues that an alternative research path is possible. Building on the distinction between prevalence and scope, it proposes two types of generality: the generality of a phenomenon within a specified scope and the generality of a theory. Correspondingly, it identifies two directions for research development: delimitation of the scope and generalization of a theory. Finally, the paper argues that research development based on this framework can be understood as progressive in the Lakatosian sense. While Schoenfeld’s framework suggests directions for individual studies, this framework guides competing research programmes by enabling both to progress through scope delimitation. en-copyright= kn-copyright= en-aut-name=UegataniYusuke en-aut-sei=Uegatani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshibashiIppo en-aut-sei=Ishibashi en-aut-mei=Ippo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Hiroshima University High School kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= en-keyword=Schoenfeld’s heuristic framework for situating research studies kn-keyword=Schoenfeld’s heuristic framework for situating research studies en-keyword=prevalence kn-keyword=prevalence en-keyword=generality kn-keyword=generality en-keyword=scope kn-keyword=scope en-keyword=delimitation of scope kn-keyword=delimitation of scope END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=3003 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photooxidative Copper(II) Catalysis for Promoting anti-Markovnikov Hydration of Alkenes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoredox catalysis enables the generation of radical intermediates under mild conditions, yet photoredox catalysts have heavily relied on precious transition metal complexes. Therefore, the development of photocatalysts based on earth-abundant metals is increasingly demanded. Here, we report a highly photooxidative capability of a heteroleptic copper(II) complex for promoting anti-Markovnikov hydration of alkenes. The copper(II) complex containing bathophenanthroline and 3,4-dimethoxybenzenethiolate ligands is generated in situ from copper(II) chloride dihydrate. Upon visible-light irradiation, the copper(II) complex is photoexcited and exhibits an excited-state lifetime sufficiently long to oxidize various alkenes, including aliphatic substrates. Consequently, anti-Markovnikov hydration can be achieved under mild conditions, and the late-stage functionalization of natural products and pharmaceutical derivatives is also feasible. The developed catalytic system can be extended for photooxidative reactions of alkenes, such as intramolecular cyclization reactions and anti-Markovnikov addition of nucleophiles other than water. en-copyright= kn-copyright= en-aut-name=OkuNaoki en-aut-sei=Oku en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukeKeito en-aut-sei=Fuke en-aut-mei=Keito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuiRikako en-aut-sei=Masui en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuiYasunori en-aut-sei=Matsui en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkedaHiroshi en-aut-sei=Ikeda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiuraTomoya en-aut-sei=Miura en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka Metropolitan University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka Metropolitan University kn-affil= affil-num=7 en-affil=Division of Applied Chemistry, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Juniperus sabina coverage on plant community structure in semiarid areas of China en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plant interactions are one of the fundamental processes shaping the structure and function of plant communities and help create species diversity. Species diversity affects the current functioning of ecosystems and their resistance and resilience to future climate change. In harsh environments such as drylands, positive plant?plant interactions are important in promoting species diversity. Juniperus sabina is an evergreen shrub that is native to the semiarid areas of northern China. Because J. sabina can modify some harsh environmental conditions in its role as a nurse plant, it is expected to facilitate species diversity, although it may exhibit allelopathic inhibition. Previous research has only examined effects of J. sabina coverage onα-diversity in a single-year, and its effects on the β-diversity of the plant community structure in the local ecosystem are still unclear. We compared environmental conditions and plant species composition inside and outside of 11 J. sabina patches to evaluate the effects of its coverage on the species diversity of the understory community structure through modifying microhabitat conditions. Water and nutrient conditions were higher inside the patches, whereas light conditions were higher outside. More perennial herbs and C3 plants were found inside and more annual herbs and C4 plants were found outside. There were different trends in α-diversity each year, while β-diversity was consistently greater inside the patches. This research suggests that the coverage of J. sabina can drive different community structures by providing heterogeneous environmental conditions, and would increase plant species diversity in the local ecosystem. en-copyright= kn-copyright= en-aut-name=QinLong en-aut-sei=Qin en-aut-mei=Long kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamabayashiAyaka en-aut-sei=Yamabayashi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoTetsuya K. en-aut-sei=Matsumoto en-aut-mei=Tetsuya K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangGuosheng en-aut-sei=Zhang en-aut-mei=Guosheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamanakaNorikazu en-aut-sei=Yamanaka en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirobeMuneto en-aut-sei=Hirobe en-aut-mei=Muneto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikiNaoko H. en-aut-sei=Miki en-aut-mei=Naoko H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=College of Ecology and Environment, Inner Mongolia Agricultural University kn-affil= affil-num=5 en-affil=Arid Land Research Center, Tottori University kn-affil= affil-num=6 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= en-keyword=Nurse plant kn-keyword=Nurse plant en-keyword=Plant species diversity kn-keyword=Plant species diversity en-keyword=Plant species coexistence kn-keyword=Plant species coexistence en-keyword=Plant?plant interactions kn-keyword=Plant?plant interactions en-keyword=Mu Us sandy land kn-keyword=Mu Us sandy land END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=530 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photosynthetic Response of Larix gmelinii var. japonica Saplings After Exogenous Glutathione Foliar Application en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sapling survival and growth depend on photosynthetic assimilates. Therefore, improving physiological performance during early stages may enhance subsequent performance and nursery production. This study evaluated whether exogenous oxidized glutathione (GSSG), reported to enhance photosynthesis, improves the photosynthetic, physiological, and growth-related traits of Larix gmelinii var. japonica saplings. Sixteen saplings were assigned to four treatments: GSSG, 5-aminolevulinic acid, Hyponex, and a water control. Photosynthetic, nitrogen-related, and growth traits were measured before treatment and at 3, 6, 13, and 31 days after treatment, and biomass was assessed after three months. The GSSG treatment showed no difference in the net CO2 assimilation rate (Amax) compared with the control, but exhibited a significantly earlier peak at 6 days than the other treatments. This response was supported by the stability of GSSG-treated saplings against photoinhibition (Fv/Fm) and a tendency toward greater resilience to midday light stress (ΦPSII). Enhanced photosynthetic performance was associated with reduced carbon and nitrogen fluctuations and was accompanied by numerically greater root and stem biomass in the 2024 terminal shoots. Although fertilization effects were generally weak and transient, GSSG elicited notable responses, suggesting that the immediate enhancement of photosynthesis underlies its impact. However, its antioxidant properties under stressful conditions warrant further investigation. en-copyright= kn-copyright= en-aut-name=RahayuResa Sri en-aut-sei=Rahayu en-aut-mei=Resa Sri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshizukaWataru en-aut-sei=Ishizuka en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaritaAyu en-aut-sei=Narita en-aut-mei=Ayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyataRie en-aut-sei=Miyata en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MikiNaoko H. en-aut-sei=Miki en-aut-mei=Naoko H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KonHirokazu en-aut-sei=Kon en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyazakiYuko en-aut-sei=Miyazaki en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=3 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=4 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=5 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil= Forestry Research Institute, Hokkaido Research Organization kn-affil= affil-num=7 en-affil= Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=exogenous glutathione kn-keyword=exogenous glutathione en-keyword=foliar fertilizer kn-keyword=foliar fertilizer en-keyword=Larix gmelinii var. japonica kn-keyword=Larix gmelinii var. japonica en-keyword=photosystem II quantum yield kn-keyword=photosystem II quantum yield en-keyword=photosynthetic rate kn-keyword=photosynthetic rate END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=181 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hypernatremia during the first week of life in very preterm infants and neurodevelopmental outcomes at 3 to 4 years of age: a cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Hypernatremia is a common electrolyte disorder in both term and preterm infants. Previous studies have suggested a correlation between hypernatremia and short-term complications in preterm infants, such as intraventricular hemorrhage and chronic lung disease. However, the relationship between hypernatremia and neurodevelopmental outcomes is less well understood. This study aimed to assess the association between hypernatremia during the first week of life and neurodevelopmental outcomes at 3?4 years of age in very preterm infants.
Methods This single-center, retrospective cohort study analyzed data from preterm infants born at less than 32 weeks of gestation between 2010 and 2020. Infants with peak whole blood sodium levels?>?145 mEq/L during the first week of life were included in the hypernatremia group and those with ??145 mEq/L in the non-hypernatremia group. The primary outcome was neurodevelopmental impairment (NDI) at 3?4 years of age, defined as developmental impairment (developmental quotient? Results Of 272 infants with neurodevelopmental data, 82 and 190 infants were in the hypernatremia and non-hypernatremia groups, respectively. The median (interquartile range) gestational age and birth weight were 26.4 (25.1?28.0) and 28.7 (26.6?30.3) weeks and 860 (670?1062) and 997 (778?1264) g for infants in the hypernatremia and non-hypernatremia groups, respectively. Infants in the hypernatremia group had a greater incidence of NDI (29.3% vs. 14.7%, adjusted risk ratio [RR] 1.75, 95% CI 1.08?2.84) and cerebral palsy (8.5% vs. 1.6%, adjusted RR 5.5, 95% CI 1.72?17.63) than those in the non-hypernatremia group.
Conclusions Hypernatremia during the first week of life was associated with an increased risk of NDI at 3?4 years of age in very preterm infants. en-copyright= kn-copyright= en-aut-name=MurakamiMichiko en-aut-sei=Murakami en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiAkihito en-aut-sei=Takeuchi en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraMakoto en-aut-sei=Nakamura en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KageyamaMisao en-aut-sei=Kageyama en-aut-mei=Misao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=5 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= en-keyword=Hypernatremia kn-keyword=Hypernatremia en-keyword=Development kn-keyword=Development en-keyword=Very preterm kn-keyword=Very preterm en-keyword=Cerebral palsy kn-keyword=Cerebral palsy END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=6 article-no= start-page=e70582 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors for Waiting List Mortality in Lung Transplant Candidates With Post‐Hematopoietic Stem Cell Transplantation Non‐Infectious Pulmonary Complications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Late-onset non-infectious pulmonary complications (LONIPCs) following hematopoietic stem cell transplantation (HSCT) are a known indication for need of lung transplantation. This study aimed to clarify the clinical characteristics of patients with LONIPCs after HSCT who were registered for lung transplantation and reveal the risk factors for waiting list mortality.
Methods: We retrospectively reviewed the clinical data of patients with LONIPCs after allogeneic HSCT who were referred to Okayama University Hospital and registered in the Japan Organ Transplant Network for deceased-donor lung transplantation between 2005 and 2023. Pediatric patients aged <18 years at the time of registration were excluded.
Results: Thirty-four patients were included in this study. Notably, two distinct phenotypic groups were identified: One with a bronchiolitis obliterans pattern on high-resolution computed tomography and a mixed ventilatory defect, and the other with a pleuroparenchymal fibroelastosis pattern and a restrictive ventilatory defect. The median waiting duration for a deceased-donor lung transplant was 662 days, and 16 patients died during the waiting period. The cumulative incidence of waiting list mortality was 20.6% (95% confidence interval [CI], 8.9%?35.6%) at 1 year and 46.1% (95% CI, 27.8%?62.7%) at 3 years. A history of pneumothorax, greater dyspnea on exertion, and higher serum Krebs von den Lungen-6 levels were associated with an increased risk of waiting list mortality.
Conclusion: In patients with LONIPCs after HSCT, a history of pneumothorax may be a marker of a poor prognosis and could serve as a criterion for referral of lung transplantation. en-copyright= kn-copyright= en-aut-name=HigoHisao en-aut-sei=Higo en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SenooSatoru en-aut-sei=Senoo en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakimotoSatoko en-aut-sei=Makimoto en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaganoTomohiro en-aut-sei=Nagano en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoHaruchika en-aut-sei=Yamamoto en-aut-mei=Haruchika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=hematopoietic stem cell transplantation kn-keyword=hematopoietic stem cell transplantation en-keyword=late-onset non-infectious pulmonary complications kn-keyword=late-onset non-infectious pulmonary complications en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=pneumothorax kn-keyword=pneumothorax END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=017803 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pressure calibrations of high-pressure large-volume presses at HPSTAR en-subtitle= kn-subtitle= en-abstract= kn-abstract=Large-volume presses (LVPs) are widely utilized in diverse research fields?including high-pressure physics, chemistry, materials science, and Earth and planetary sciences?to investigate the physical and chemical properties of materials under extreme high-pressure and high-temperature conditions. A prerequisite for achieving reproducible property measurements is the determination and control of pressure within experimental setups. However, the lack of precise pressure calibration in LVPs hinders the broader application of such devices in ultrahigh-pressure studies. This study employs a suite of standard phase transition-based pressure markers?comprising metallic conductors, semiconductors, and minerals?through both in situ and ex situ identification approaches, to establish pressure calibration curves ranging from 0.4 to >30 GPa for various types of LVP installed at the Center for High Pressure Science and Technology Advanced Research (HPSTAR), Beijing, including piston?cylinder, cubic, and multi-anvil presses. The results provide a unified and traceable pressure reference for high-pressure experiments conducted at HPSTAR, while also offering technical guidance and calibration standards for other researchers utilizing similar LVP systems, thereby enabling more consistent comparison between different laboratories. This work facilitates the advancement of LVP research toward broader applications in higher-pressure regimes. en-copyright= kn-copyright= en-aut-name=XuYongjiang en-aut-sei=Xu en-aut-mei=Yongjiang

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

kn-title=Spin Transition of Fe3+ in δ-(Al,Fe)OOH and Implication for Mid-Lower Mantle Seismic Heterogeneities en-subtitle= kn-subtitle= en-abstract= kn-abstract=δ-(Al,Fe)OOH is an important water carrier and plays a critical role on Earth's deep water cycle. Lattice parameters of δ-(Al0.89Fe0.11)OOH were measured by synchrotron single-crystal X-ray diffraction at simultaneously high temperature and pressure up to 65 GPa and 800 K in diamond anvil cells. The results reveal that the spin crossover increases from 30 to 37 GPa at 300 K to 36?48 GPa at 700 K. Moreover, at the spin crossover, the KT and VΦ of δ-(Al0.89Fe0.11)OOH occur significant elastic softening, with maximum reductions of 50% on KT and 29% on VΦ at 33 GPa and 300 K to 37% on KT and 23% on VΦ at 41 GPa and 700 K. The anomalous elastic properties of δ-(Al,Fe)OOH at the spin crossover enhance our understanding of local seismic observations anomalies and help identify potential water-rich regions in the mid-lower mantle. en-copyright= kn-copyright= en-aut-name=ZhaoChaoshuai en-aut-sei=Zhao en-aut-mei=Chaoshuai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaoZhu en-aut-sei=Mao en-aut-mei=Zhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuYingxin en-aut-sei=Yu en-aut-mei=Yingxin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SunNingyu en-aut-sei=Sun en-aut-mei=Ningyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangJianbo en-aut-sei=Zhang en-aut-mei=Jianbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangYuzhu en-aut-sei=Wang en-aut-mei=Yuzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=2 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=3 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=4 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=5 en-affil=State Key Laboratory of Precision Geodesy, University of Science and Technology of China kn-affil= affil-num=6 en-affil=Center for High Pressure Science and Technology Advanced Research kn-affil= affil-num=7 en-affil=Shanghai Advanced Research Institute, Chinese Academy of Sciences kn-affil= affil-num=8 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=spin transition kn-keyword=spin transition en-keyword=δ-(Al,Fe)OOH kn-keyword=δ-(Al,Fe)OOH en-keyword=seismic heterogeneities kn-keyword=seismic heterogeneities en-keyword=deep water cycle kn-keyword=deep water cycle en-keyword=high temperature and high pressure kn-keyword=high temperature and high pressure END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=3 article-no= start-page=e2025GL118991 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep-mantle minerals, FeO-rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally-heated diamond anvil cells. Thermoelastic modeling of our results and literature data along a representative areotherm showed that Vp and Vs of FeO-bearing ringwoodite are approximately 7.5% and 11.0% higher than that of the majorite. Our results reveal that velocity profiles of these Martian deep-mantle minerals are more sensitive to variations in the ringwoodite/majorite (Mg/Si) ratio than to thermal and FeO chemical perturbations. Our best-fit velocity model to a recent seismic model by Samuel et al. (2023, https://doi.org/10.1038/s41586-023-06601-8) indicates the Martian mantle contains approximately 67 vol.% ringwoodite and 33 vol.% majorite, suggesting a ringwoodite-rich aggregate in the Martian lowermost solid mantle. The ringwoodite-majorite mantle likely co-evolved with the FeO and other incompatible elements in the molten silicate layer above the Martian core-mantle boundary. en-copyright= kn-copyright= en-aut-name=LiLuo en-aut-sei=Li en-aut-mei=Luo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RyuYoung Jay en-aut-sei=Ryu en-aut-mei=Young Jay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangDongzhou en-aut-sei=Zhang en-aut-mei=Dongzhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CharitonStella en-aut-sei=Chariton en-aut-mei=Stella kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PrakapenkaVitali B. en-aut-sei=Prakapenka en-aut-mei=Vitali B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LinJung‐Fu en-aut-sei=Lin en-aut-mei=Jung‐Fu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences, The University of Texas at Austin kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=4 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=5 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=6 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=7 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences, The University of Texas at Austin kn-affil= en-keyword=sound velocity kn-keyword=sound velocity en-keyword=ringwoodite kn-keyword=ringwoodite en-keyword=majorite kn-keyword=majorite en-keyword=Martian mantle kn-keyword=Martian mantle en-keyword=FeO-rich kn-keyword=FeO-rich END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=2 article-no= start-page=e2025GL118147 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Davemaoite Elasticity Reveals Slab‐Induced Heterogeneity in the Mantle Transition Zone en-subtitle= kn-subtitle= en-abstract= kn-abstract=The observed 2%?7% low-shear velocity (VS) anomalies near the subducted slab at the bottom mantle transition zone (MTZ) indicate strong lateral heterogeneity, which is commonly attributed to subducted oceanic crust. However, davemaoite, a major constituent of the subducted oceanic crust, has been poorly constrained in its elasticity, hindering accurate velocity modeling and obscuring the origin of these low-velocity features. Here we report single-crystal elasticity of Ti-bearing davemaoite with the composition of Ca(Si0.57Ti0.43)O3 under high pressure-temperature and found that Ti incorporation significantly reduces velocities and alters the pressure dependence of the shear modulus. Further velocity modeling demonstrated that subducted crusts with varying Ti content have seismic signatures of 1.7(2)?6.8(5)% low-VS at the bottom MTZ, consistent with the observed low-VS structure in the region. These findings highlight the role of slab-derived chemical heterogeneity in generating mantle seismic anomalies and provide new experimental constraints on the structure and dynamics of the deep Earth. en-copyright= kn-copyright= en-aut-name=YuYingxin en-aut-sei=Yu en-aut-mei=Yingxin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhangDongzhou en-aut-sei=Zhang en-aut-mei=Dongzhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiLuo en-aut-sei=Li en-aut-mei=Luo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaoZhu en-aut-sei=Mao en-aut-mei=Zhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SunNingyu en-aut-sei=Sun en-aut-mei=Ningyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangDenglei en-aut-sei=Wang en-aut-mei=Denglei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LiJing en-aut-sei=Li en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZhaoChaoshuai en-aut-sei=Zhao en-aut-mei=Chaoshuai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=QianCheng en-aut-sei=Qian en-aut-mei=Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WeiYingzhan en-aut-sei=Wei en-aut-mei=Yingzhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=LiXinyang en-aut-sei=Li en-aut-mei=Xinyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WangYuzhu en-aut-sei=Wang en-aut-mei=Yuzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=2 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=3 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=4 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=5 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=6 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=7 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=8 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=9 en-affil=State Key Laboratory of Precision Geodesy, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=10 en-affil=State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences kn-affil= affil-num=11 en-affil=State Key Laboratory of High Pressure and Superhard Materials, College of Physics, Jilin University kn-affil= affil-num=12 en-affil=State Key Laboratory of High Pressure and Superhard Materials, College of Physics, Jilin University kn-affil= affil-num=13 en-affil=Shanghai Advanced Research Institute, Chinese Academy of Sciences kn-affil= affil-num=14 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Ti-bearing davemaoite kn-keyword=Ti-bearing davemaoite en-keyword=single-crystal elasticity kn-keyword=single-crystal elasticity en-keyword=slab-induced heterogeneity kn-keyword=slab-induced heterogeneity en-keyword=mantle transition zone kn-keyword=mantle transition zone END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=1850114 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260529 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bee larvae ameliorate andropause-like symptoms via a hormone-independent, antioxidant mechanism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Late-onset hypogonadism (LOH), also known as the male menopause, is characterized by a decline in sexual function as well as various physical and psychological symptoms, including anxiety. Although bee larvae have historically been utilized as a traditional food and medicine, their efficacy and physiological mechanisms of action against male menopausal symptoms remain unclear. In this study, we investigated the effects of bee larvae (BL) on sexual and anxiety-like behaviors using two rodent models of the male menopause: aged rats and castrated mice. In the aged rat model (64 weeks old), dietary BL supplementation for 4 weeks significantly attenuated the age-associated decline in ejaculation frequency compared to controls, while no significant effects were observed on mount or intromission frequencies. Notably, plasma analysis revealed no significant differences in testosterone or dihydrotestosterone levels between the BL and control groups. To elucidate the underlying mechanism, we evaluated sexual function using a castrated mouse model. While BL supplementation did not affect sexual behavior in intact mice, post-castration BL treatment significantly shortened intromission latency without altering mount frequency. In the elevated plus maze test, BL significantly alleviated castration-induced anxiety-like behaviors and improved exploratory activity. Furthermore, in vitro assays demonstrated that the BL extract exerts potent protective effects against oxidative stress, a pathological factor contributing to both erectile dysfunction and anxiety. These results suggest that BL improves erectile function and anxiety via hormone-independent mechanisms, potentially by mitigating oxidative stress in vascular and neural tissues. Thus, bee larvae represent a promising functional food for ameliorating the multi-faceted physical and psychological symptoms associated with male menopause. en-copyright= kn-copyright= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkumuraNobuaki en-aut-sei=Okumura en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtiTakumi en-aut-sei=Oti en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute for Bee Products & Health Science, Yamada Bee Company, Inc. kn-affil= affil-num=3 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=bee larvae kn-keyword=bee larvae en-keyword=late-onset hypogonadism kn-keyword=late-onset hypogonadism en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=sexual behavior kn-keyword=sexual behavior END start-ver=1.4 cd-journal=joma no-vol=130 cd-vols= no-issue=8 article-no= start-page=e2025JB031715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Linking the Spin Transition of Ferric Iron in δ‐(Al,Fe)OOH to Water Storage in the Lower Mantle en-subtitle= kn-subtitle= en-abstract= kn-abstract=As the most massive geochemical reservoir, the lower mantle affects the Earth's budget of volatile elements, including hydrogen or H2O. The properties of minerals in the lower mantle are further affected by changes in the electronic configurations of iron cations, that is, by spin transitions. The feedback between spin transitions and potential storage of H2O in solid hydrous phases in the lower mantle, however, remains unexplored. By combining high-pressure nuclear resonant inelastic X-ray scattering and high-pressure high-temperature X-ray diffraction experiments, we constrained the thermal equation of state of δ-(Al,Fe)OOH, a member of the phase H solid solution. Based on the derived thermal equation of state of δ-(Al,Fe)OOH and the underlying thermodynamic model, we calculate the excess Gibbs free energy that arises from the spin transition of ferric iron in this compound and evaluate the effect on phase equilibria. The results of our analysis show that the spin transition of ferric iron in phase H may significantly reduce the thermodynamic activity and hence the concentration of H2O in a coexisting hydrous melt. As a consequence, nominally anhydrous minerals of the lower mantle may become dehydrated in the presence of phase H. Our analysis further suggests that, under certain conditions, the spin transition may expand the thermal stability of Fe3+-bearing phase H and create a geochemical link between the storage of H2O in phase H and ferric iron in the lower mantle. en-copyright= kn-copyright= en-aut-name=BuchenJohannes en-aut-sei=Buchen en-aut-mei=Johannes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PardoOlivia S. en-aut-sei=Pardo en-aut-mei=Olivia S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DobrosavljevicVasilije V. en-aut-sei=Dobrosavljevic en-aut-mei=Vasilije V. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SturhahnWolfgang en-aut-sei=Sturhahn en-aut-mei=Wolfgang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=CharitonStella en-aut-sei=Chariton en-aut-mei=Stella kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GreenbergEran en-aut-sei=Greenberg en-aut-mei=Eran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToellnerThomas S. en-aut-sei=Toellner en-aut-mei=Thomas S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=JacksonJennifer M. en-aut-sei=Jackson en-aut-mei=Jennifer M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Bayerisches Geoinstitut, Universit?t Bayreuth kn-affil= affil-num=2 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= affil-num=3 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= affil-num=4 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= affil-num=5 en-affil=Now at Institute for Planetary Materials, Okayama University kn-affil= affil-num=6 en-affil=GSECARS, The University of Chicago kn-affil= affil-num=7 en-affil=GSECARS, The University of Chicago kn-affil= affil-num=8 en-affil=Advanced Photon Source, Argonne National Laboratory kn-affil= affil-num=9 en-affil=Seismological Laboratory, California Institute of Technology kn-affil= en-keyword=spin transition kn-keyword=spin transition en-keyword=phase H kn-keyword=phase H en-keyword=lower mantle kn-keyword=lower mantle en-keyword=high pressure kn-keyword=high pressure en-keyword=equation of state kn-keyword=equation of state en-keyword=phonon density of states kn-keyword=phonon density of states END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=3 article-no= start-page=86 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immediate and delayed effects of thermal stress on fever-associated seizures in children: A time-stratified case-crossover study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to examine the non-linear and delayed effects of thermal stress, measured by the hourly Universal Thermal Climate Index (UTCI), on the risk of pediatric fever-associated seizures (FAS). We conducted a time-stratified case-crossover study in Okayama, Japan (May 2015?March 2023), analyzing 3,201 ambulance-attended FAS cases in children younger than 7 years. Using a distributed lag non-linear model (DLNM) with a 144-h lag, we estimated the association between UTCI and FAS. The analysis revealed a bimodal exposure?response relationship. Moderate Cold Stress (10th percentile, ?1.6 °C) was associated with a significant cumulative odds ratio (OR) of 2.22 (95% CI: 1.22?4.06). Risk also increased at the upper range of No Thermal Stress (24.2 °C; cumulative OR 2.74, 95% CI: 1.63?4.63), extending into Moderate Heat Stress (28.7 °C; cumulative OR 2.26, 95% CI: 1.33?3.84). These effects were primarily delayed to 72?96 h for Moderate Cold and reached a peak around 100 h for Moderate Heat. Strong Heat Stress showed immediate but non-significant risk patterns. These findings suggest that infection-mediated pathways likely drive the observed bimodal risk pattern, demonstrate the utility of high-resolution bioclimatic indices, and can inform the development of temperature-specific public health alerts. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

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

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

en-title= kn-title=Predictive value of simple echocardiographic parameters for screening pulmonary hypertension under the revised definition: a study for general hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The current guideline recommends a peak tricuspid regurgitation velocity (TRV) ?2.9 m/s on echocardiography for pulmonary hypertension (PH) screening; however, this threshold was based on the previous PH definition (mean pulmonary arterial pressure (mPAP) ?25?mm Hg) and derived largely from PH referral centres.
Methods We retrospectively analysed 755 patients who underwent both transthoracic echocardiography and right heart catheterisation at two general hospitals. The discrimination of peak TRV and estimated right atrial pressure (eRAP), derived from inferior vena cava diameter and respiratory variation, for screening for PH was assessed by receiver operating characteristic curve analysis. Optimal cut-off values were determined with the Youden Index.
Results The c-statistic for peak TRV in detecting PH was 0.82 (95% CI 0.79 to 0.85). An optimal cut-off of 2.7 m/s provided higher sensitivity (72%) than the conventional 2.9 m/s threshold (60%) while maintaining high specificity (82%). In 681 patients with available TRV and eRAP data, adding eRAP improved discrimination compared with TRV alone (c-statistic 0.83 vs 0.80; net reclassification improvement=0.14, p=0.002). eRAP ?5?mm Hg was associated with a higher risk of PH, and the combination of elevated TRV and eRAP yielded the strongest association.
Conclusion For screening under the revised PH definition, a peak TRV of 2.7 m/s is suggested as the optimal cut-off. Although TRV alone showed good discriminative performance, combining it with eRAP further improved diagnostic accuracy using simple echocardiographic measures. en-copyright= kn-copyright= en-aut-name=FukudaYoshitake en-aut-sei=Fukuda en-aut-mei=Yoshitake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TayaSatoshi en-aut-sei=Taya en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EjiriKentaro en-aut-sei=Ejiri en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DohiYoshihiro en-aut-sei=Dohi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Kure Kyosai Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=302 cd-vols= no-issue=6 article-no= start-page=113085 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A photoactivatable Cre-loxP system for spatiotemporal genetic manipulation in mouse taste buds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Conventional genetic approaches, including global gene KO and conditional KO strategies such as the Cre-loxP system, have some limitations arising from systemic effects or insufficient temporal resolution. The recently developed photoactivatable Cre (PA-Cre) system may have a potential to improve spatiotemporal control of gene manipulation. In this study, we established and validated the feasibility of the PA-Cre system using taste buds as a model. We generated TRE-PA-Cre:R26-rtTA/tdTomato mice to evaluate blue-light-induced Cre recombinase activity. Through systematic optimization of illumination parameters, we found that a single session of blue-light-illumination resulted in limited recombination efficiency, whereas a multisession illumination strategy markedly increased recombination efficiency. To further assess the utility of the PA-Cre system for gene KO, we generated TRE-PA-Cre:R26-rtTA:Tas1r3-flox mice and targeted a taste-related gene Tas1r3. Genomic DNA quantitative PCR and reverse transcription-quantitative PCR both showed partial reductions in Tas1r3 at the DNA and mRNA levels, respectively. Behavioral assays further revealed a selective decrease in sensitivity to sweet and umami stimuli. Together, these findings demonstrate PA-Cre-mediated gene manipulation in taste buds and establish a practical optical activation paradigm, providing a high-spatiotemporal-resolution tool for investigating gene function in optically targeted regions. en-copyright= kn-copyright= en-aut-name=ZuoYu en-aut-sei=Zuo en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaYasuhiro en-aut-sei=Yamada en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoTomoka en-aut-sei=Takao en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaradaTakeshi en-aut-sei=Takarada en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KokabuShoichiro en-aut-sei=Kokabu en-aut-mei=Shoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Molecular Pathology, Graduate School of Medicine and Faculty of Medicine, The University of Tokyo kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Biochemistry, Kyushu Dental University kn-affil= affil-num=8 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cre-loxP kn-keyword=Cre-loxP en-keyword=genetic manipulation kn-keyword=genetic manipulation en-keyword=mouse kn-keyword=mouse en-keyword=photoactivatable Cre kn-keyword=photoactivatable Cre en-keyword=spatiotemporal kn-keyword=spatiotemporal en-keyword=taste kn-keyword=taste END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=105 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Programmable synthesis of alkaloidal frameworks integrating Michael acceptor generates covalent probes for targeting POLE3 in HBV replication en-subtitle= kn-subtitle= en-abstract= kn-abstract=The growing need for effective HBV treatments and lead compounds with novel mechanisms prompted us to explore synthetic strategies for generating skeletally diverse alkaloidal Michael acceptors. Our approach uniquely embeds Michael acceptors directly within multicyclic alkaloid-inspired frameworks, exploiting the azepinoindole scaffold?a privileged structure in indole alkaloids. A single-step assembly between the versatile intermediate 13 with methyl propiolate 14 or its derivatives enabled the rapid and divergent synthesis of six alkaloidal Michael acceptors (15?20). This strategy facilitated systematic diversification of three-dimensional functional group arrangements and precise tuning of the electronic and steric properties of the embedded α,β-unsaturated carbonyl moieties. The optimal hit 15 inhibited hepatitis B surface antigen (HBsAg) production with an IC50 of 2.48 μM and significantly reduced levels of covalently closed circular DNA (cccDNA), the master template of HBV. Unlike existing nucleoside/nucleotide-based anti-HBV drugs that primarily inhibit reverse transcription, the alkaloidal Michael acceptor 15 suppressed both cccDNA and relaxed circular DNA (rcDNA) levels, suggesting a potential pathway toward a functional HBV cure. Our study also streamlined the target identification by leveraging the covalent binding properties of the Michael acceptors and the operational simplicity of biotin- or fluorescent-tag attachment via a pre-installed alkyne moiety. Competitive pull-down experiments identified several potential target proteins, involving DNA polymerase epsilon subunit 3 (POLE3). Notably, the alkaloidal Michael acceptor 15 was demonstrated to covalently modify Cys51 in POLE3, providing new insights into virus?host interactions and opening novel avenues for targeted anti-HBV therapies. This approach represents a significant advance beyond traditional screening methods and underscores the potential of skeletally diverse alkaloidal Michael acceptors in antiviral drug development.

endoscopic papillectomy: a multicenter propensity score-matched analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Delayed bleeding is a frequent and serious complication after endoscopic papillectomy (EP). Second-look endoscopy (SLE) is often scheduled on the following day for wound assessment and prophylactic hemostasis, but its clinical value remains unclear.
Objectives: This study evaluated the effectiveness of SLE in preventing delayed bleeding after EP.
Design: This study was a multicenter, retrospective cohort study.
Methods: We retrospectively reviewed 132 consecutive patients who underwent EP at nine high-volume centers between 2003 and 2024 (SLE group, n?=?73; non-SLE group, n?=?59). Propensity score matching was performed to balance baseline characteristics. The primary outcome was delayed bleeding, and secondary outcomes were risk factors, the impact of prophylactic hemostasis during SLE, and hospital stay.
Results: After matching, 43 patients were included in each group. The incidence of delayed bleeding did not differ between the SLE and non-SLE groups (14% vs 9%, p?=?0.50). Multivariate analysis identified a lack of preventive clipping closure as the only independent risk factor (odds ratio 15, 95% confidence interval 1.3?177, p?=?0.030). Prophylactic hemostasis during SLE did not reduce bleeding but was associated with prolonged hospitalization (13 vs 9?days, p?=?0.012).
Conclusion: Routine SLE after EP does not reduce delayed bleeding. Moreover, prophylactic hemostasis in asymptomatic patients may unnecessarily prolong hospitalization. Hemostasis should be reserved for patients who develop clinical signs of bleeding. en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei=

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

candidate therapies for multiple sclerosis: inverse signal analysis using the FDA adverse event reporting system and preclinical validation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Alterations in bile acid metabolism have been observed in individuals with multiple sclerosis (MS), yet the therapeutic implications of bile acid supplementation remain uncertain.
Methods: We conducted a two-stage study integrating pharmacovigilance analysis with preclinical validation to evaluate bile acid derivatives as candidate therapies for MS. A disproportionality analysis of the FDA Adverse Event Reporting System (FAERS; Q4/2003?Q2/2025) was performed to identify inverse associations between MS and bile acid preparations. The effects of ursodeoxycholic acid (UDCA) and obeticholic acid (6-ECDCA) were evaluated in a therapeutic experimental autoimmune encephalomyelitis (EAE) model, with treatment initiated after disease onset.
Results: Among 13,734,539 FAERS reports, 75,659 involved MS. Inverse associations were identified for UDCA (odds ratio [OR]: 0.197, 95% confidence interval [CI]: 0.117?0.333) and 6-ECDCA (OR: 0.128, 95% CI: 0.041?0.396). In the EAE model, UDCA was associated with lower clinical scores at the peak (day 18) and late phases (days 26?28), whereas 6-ECDCA showed only a non-significant trend toward improvement at day 28.
Conclusion: This two-stage investigation highlights the potential utility of pharmacovigilance-guided approaches for identifying therapeutic candidates. Bile acid derivatives, particularly UDCA, are biologically plausible candidates meriting further investigation in the context of MS. en-copyright= kn-copyright= en-aut-name=AsadaMizuho en-aut-sei=Asada en-aut-mei=Mizuho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MikamiTakahisa en-aut-sei=Mikami en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GodaMitsuhiro en-aut-sei=Goda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SonodaYuhei en-aut-sei=Sonoda en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NiimuraTakahiro en-aut-sei=Niimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChumaMasayuki en-aut-sei=Chuma en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UesawaYoshihiro en-aut-sei=Uesawa en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshizawaKeisuke en-aut-sei=Ishizawa en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Medical Molecular Informatics, Meiji Pharmaceutical University kn-affil= affil-num=2 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=3 en-affil=Department of Neurology, Massachusetts General Hospital kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Pharmacology and Therapeutics, Tokushima University Graduate School of Biomedical Sciences kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy and Pharmacology, Asahikawa Medical University and University Hospital kn-affil= affil-num=9 en-affil=Department of Medical Molecular Informatics, Meiji Pharmaceutical University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= en-keyword=Bile acids kn-keyword=Bile acids en-keyword=Multiple sclerosis kn-keyword=Multiple sclerosis en-keyword=Database analysis kn-keyword=Database analysis en-keyword=Drug repositioning kn-keyword=Drug repositioning en-keyword=Experimental autoimmune encephalomyelitis kn-keyword=Experimental autoimmune encephalomyelitis END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=48 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adverse events of romidepsin versus tucidinostat for peripheral T-cell lymphoma: a pharmacovigilance study using the Japanese adverse drug event report database en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of lymphomas with poor prognosis, particularly in patients with relapsed or refractory (R/R) disease. Romidepsin and tucidinostat are histone deacetylase inhibitors used to treat R/R PTCL. No head-to-head post-marketing surveillance studies have compared adverse events (AEs) between the two agents. In this brief report, the AE profiles of romidepsin and tucidinostat were compared using the Japanese Adverse Drug Event Report (JADER) database to facilitate their differentiation and promote the management of AEs.
Methods We conducted a descriptive analysis using data from the JADER database from April 2018 to July 2025. The reported AEs for romidepsin and tucidinostat were extracted and classified according to preferred terms (PTs) and system organ classes (SOCs). Reporting odds ratios with 95% confidence intervals were calculated to compare the AE profiles between the groups.
Results In total, 998,397 reports were analysed for all drugs, including 323 for romidepsin and 753 for tucidinostat. Compared with all drugs, both agents showed significant disproportionality signals in four SOCs: Blood and lymphatic system disorders; General disorders and administration site conditions; Investigations; and Neoplasms benign, malignant and unspecified. Romidepsin exhibited additional significant signals in six SOCs: Cardiac disorders, Eye disorders, Gastrointestinal disorders, Immune system disorders, Infections and infestations, and Metabolism and nutrition disorders. Direct comparison between the two agents revealed broader AE profiles for romidepsin, with AEs more frequently reported in eight SOCs, whereas tucidinostat showed AEs in only two SOCs. Romidepsin was associated with AEs more frequently reported in several PTs, including atrial fibrillation and gastrointestinal toxicities, such as constipation, tumour lysis syndrome, hepatotoxicity, and peripheral neuropathy, which was consistent with the results at the SOC level. In contrast, several significant PTs for tucidinostat were observed in General disorders and administration site conditions and Investigations.
Conclusions The Japanese real-world pharmacovigilance analysis showed differences in the AE profiles between romidepsin and tucidinostat. These differences in safety profiles may be useful for treatment selection and AE management in routine clinical practice among patients with R/R PTCL. Further studies are warranted to confirm these findings and better characterise the safety profiles of these agents. en-copyright= kn-copyright= en-aut-name=TakatsuNao en-aut-sei=Takatsu en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoJun en-aut-sei=Matsumoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkaYurie en-aut-sei=Oka en-aut-mei=Yurie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaiTomonori en-aut-sei=Sakai en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataNaohiro en-aut-sei=Iwata en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigashionnaTsukasa en-aut-sei=Higashionna en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Clinical Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Romidepsin kn-keyword=Romidepsin en-keyword=Tucidinostat kn-keyword=Tucidinostat en-keyword=Adverse event kn-keyword=Adverse event en-keyword=JADER kn-keyword=JADER en-keyword=Pharmacovigilance kn-keyword=Pharmacovigilance END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=9 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship Between Numbers of Patients Registered and Procedures Performed at Lung Transplantation Centers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Recently, there has been a dramatic increase in deceased lung transplantation (DLT) procedures performed in Japan. However, there is concern that the number of transplantations may reach the limit of capacity in some centers. The present study was conducted to analyze the relationship between the numbers of individuals registered for DLT by the Japan Organ Transplantation Network (JOT) and procedures subsequently performed at lung transplantation centers. Methods: Using a database and registry reports provided by the Japanese Society of Lung and Heart-lung Transplantation, the numbers of individuals registered in the JOT and DLT procedures performed from January 2014 to December 2023 were analyzed. Results: The number of registrations was found to be correlated with the number of DLTs, with the coefficient of determination (R2) 0.962 and slope of the regression line (X coefficient) 0.407. The facility with the greatest number of registrations, with a registration-to-transplantation ratio of 0.353, was identified as an outlier (p < 0.05) and excluded from analysis. This exclusion increased both the correlation coefficient value to 0.986 and X coefficient value to 0.461. Conclusions: The present analysis showed that the number of DLTs was well correlated with number of registrations at each of the transplantation facilities. Both registration and transplantation numbers have increased in the recent decade. The facility with the highest number of registrations showed a lower registration-to-transplantation ratio, because the increase in registrations outpaced the number of transplantations. en-copyright=

photon-counting detector CT for temporal bone imaging: phantom and clinical studies with helical acquisition en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To determine the extent of possible dose reduction with photon-counting detector computed tomography (PCD-CT) while maintaining image quality equivalent to that of energy-integrating detector CT (EID-CT) images at standard dose in the temporal bone.
Materials and methods: PCD-CT and EID-CT imaging quality were compared by visual evaluation of clinical temporal bone images and visual scores with Welch’s t-test at standard dose. A head phantom was used to evaluate imaging quality under dose reduction. The detectability index (d’) of the PCD-CT images at various dose levels and the EID-CT images at standard dose was evaluated. Dose reduction limit with PCD-CT used in the subsequent clinical evaluation was determined as the lowest dose with image quality equal to or better than EID-CT. The clinical equivalence of PCD-CT image quality at the determined reduced dose to that with EID-CT at standard dose was evaluated using visual scores. Equivalence was determined if the 95% confidence intervals of differences did not exceed the equivalence margin of ±1.
Results: At standard doses, PCD-CT images demonstrated significantly higher visual scores than EID-CT images (3.73 vs. 2.56 for incudomalleolar joint, 3.75 vs. 2.63 for stapes, 3.54 vs. 2.52 for cochlea, and 3.58 vs. 2.46 for facial nerve canal; all P 0.001). In the phantom study, the d’ value was 0.15 with EID-CT at standard dose and was 0.12 and 0.17 with PCD-CT at 25% and 50% of the standard dose, respectively. Clinically, the mean visual scores of PCD-CT images at 50% of the standard dose were equivalent to EID-CT images at standard dose in all regions (3.58 vs. 3.12 for incudomalleolar joint, 3.46 vs. 3.19 for stapes, 3.50 vs. 3.08 for cochlea, 3.58 vs. 3.27 for facial nerve canal).
Conclusion: PCD-CT may preserve image quality even at 50% of the standard dose in the temporal bone. en-copyright= kn-copyright= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraYuko en-aut-sei=Nakamura en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HigakiToru en-aut-sei=Higaki en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AwaiKazuo en-aut-sei=Awai en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Diagnostic Radiology, Hiroshima University kn-affil= affil-num=4 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Diagnostic Radiology, Hiroshima University kn-affil= affil-num=14 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=PCD-CT kn-keyword=PCD-CT en-keyword=EID-CT kn-keyword=EID-CT en-keyword=Dose reduction kn-keyword=Dose reduction en-keyword=Temporal bone CT kn-keyword=Temporal bone CT en-keyword=Incudomalleolar joint kn-keyword=Incudomalleolar joint en-keyword=Stapes kn-keyword=Stapes END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=2247 end-page=2258 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=Surface Plasmon Resonances in Silver Nanodendrites : Trunk Length and Branch Connectivity Dependence en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study systematically investigates how trunk length and branch connectivity govern surface plasmon resonances in silver nanodendrites in the infrared (IR) region using a computational modeling strategy. We show that a continuous conductive trunk is essential for exciting long-wavelength collective plasmon modes. In a simulated bottom-up construction scheme, the trunk length is gradually increased to conductively connect additional branches to the backbone. Our results reveal that the fundamental δ mode resonance can be deterministically tuned across the mid-infrared spectrum (from 3840 nm to 4360 nm) primarily by controlling the trunk connectivity. As the number of connected branches grows, the lowest-order collective resonance peak exhibits a systematic redshift, and its resonance wavelength scales linearly with the effective dipole length Leff of the electron oscillation path. Concurrently, new higher-order modes emerge as local resonances of the connected substructures. These observations indicate that interrupting the conductive pathway causes a global collective mode to decompose into multiple resonances associated with more weakly coupled subsystems. The established linear scaling relationship provides a highly predictable design rule for this “programmable” connectivity, offering a robust platform for advanced applications such as multi-spectral infrared imaging, selective chemical sensing, and surface-enhanced infrared absorption (SEIRA) spectroscopy, where precise, a priori control over narrow-band infrared resonances is essential. en-copyright= kn-copyright= en-aut-name=MaQingyuan en-aut-sei=Ma en-aut-mei=Qingyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KishidaYuki en-aut-sei=Kishida en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeyasuNobuyuki en-aut-sei=Takeyasu en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShojiSatoru en-aut-sei=Shoji en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Informatics and Engineering, The University of Electro-communications kn-affil= affil-num=2 en-affil=Graduate School of Informatics and Engineering, The University of Electro-communications kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Informatics and Engineering, The University of Electro-communications kn-affil= en-keyword=Silver nanodendrites kn-keyword=Silver nanodendrites en-keyword=Surface plasmon resonances kn-keyword=Surface plasmon resonances en-keyword=Conductive coupling kn-keyword=Conductive coupling en-keyword=Topological connectivity kn-keyword=Topological connectivity en-keyword=Infrared nanoantennas kn-keyword=Infrared nanoantennas en-keyword=Plasmonic metamaterials kn-keyword=Plasmonic metamaterials END start-ver=1.4 cd-journal=joma no-vol=209 cd-vols= no-issue= article-no= start-page=117914 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PPy-coated wire actuators for micromechanostimulation of cells ? identification of immediate-early responsive mechanoregulatory genes in osteoblasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mechanotransduction, i.e., the conversion of mechanical cues into biochemical signals, is essential for bone development, remodeling, and adaptation. Although mechanical loading is known to regulate osteoblast function and bone homeostasis, dissecting the early and sustained mechanotransductive responses at the microscale remains challenging due to limitations of existing in vitro models. Here, we report the development and application of a mechanostimulation system comprising a polypyrrole (PPy)-based wire actuator that expands and contracts (4 μm in radius) upon electrical actuation and enables precise, localized micromechanical stimulation of a small number of cells within standard culture formats. Using this system, we applied short-term (30 min) cyclic (Cyc30) or static (Stat30), as well as prolonged (120 min) cyclic (Cyc120) stimulations to two osteoblast-like cells (MC3T3-E1 or KUSA-A1). Subsequent transcriptomic profiling and computational network analyses revealed that Cyc30 was not capable of inducing significant changes in mRNA expression, suggesting cellular adaptation to short-term cyclic loading. In contrast, Stat30 induced the upregulation of Fos, Btg2, Egr1, and Fosl1, all known genes associated with mechanotransduction, supporting the validity and reproducibility of our experimental mechanostimulation system. Notably, two long non-coding RNAs (B930036N10Rik and 5430431A17Rik) were identified for the first time as being upregulated in response to Stat30 stimuli. Among the differentially expressed genes (DEGs) upregulated by Cyc120 stimuli, Hmox1, a stress-inducible enzyme known for its roles in maintaining cellular homeostasis and promoting survival, was the only DEG repeatedly observed across the Cyc30/Cyc120 and Stat30/Cyc120 comparisons in both cell types, potentially emerging as a key stress-response gene under prolonged mechanical loading. Collectively, these results establish the PPy-based microactuator as a powerful tool for microscale mechanobiology, and provide molecular insight into immediate-early responsive transcriptional programs underlying osteoblastic mechanoadaptation conserved across different cell types. en-copyright= kn-copyright= en-aut-name=ChenJiamin en-aut-sei=Chen en-aut-mei=Jiamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Ortega-SantosAmaia B. en-aut-sei=Ortega-Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MartinezJose G. en-aut-sei=Martinez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=JagerEdwin W.H. en-aut-sei=Jager en-aut-mei=Edwin W.H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Physics, Chemistry and Biology (IFM), Link?ping University kn-affil= affil-num=3 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Physics, Chemistry and Biology (IFM), Link?ping University kn-affil= affil-num=6 en-affil=Department of Advanced International and Information Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Physics, Chemistry and Biology (IFM), Link?ping University kn-affil= affil-num=8 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Mechanotransduction kn-keyword=Mechanotransduction en-keyword=Mechanostimulation kn-keyword=Mechanostimulation en-keyword=Osteoblasts kn-keyword=Osteoblasts en-keyword=Polypyrrole kn-keyword=Polypyrrole END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=3621 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Outcomes of Endoscopic Ultrasound-Guided Gallbladder Drainage for Acute Cholecystitis in Non-Surgical Candidates: A Multicenter Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is a minimally invasive alternative for managing acute cholecystitis in patients who are unsuitable for surgery. Although its short-term efficacy is well-established, its long-term outcomes, especially in patients with malignancy-associated cholecystitis, remain unclear. Methods: This multicenter, retrospective study included 139 patients who underwent EUS-GBD with a plastic stent for inoperable acute cholecystitis between January 2010 and October 2023. Patients were divided into two groups: a malignant group (n = 60) with cystic duct obstruction caused by cancer invasion or self-expandable metal stents, and a benign group (n = 79) with calculous or acalculous cholecystitis. The outcomes assessed included cholecystitis recurrence, time to recurrence, adverse events, and risk factors for recurrence. Results: Technical success was achieved in all patients, with an overall clinical success rate of 94.6%. Cholecystitis recurred significantly more frequently in the malignant group than in the benign group (13.3% vs. 2.5%; p = 0.015). Univariate analysis identified malignancy as a significant risk factor of recurrence (odds ratio, 5.92; p = 0.028). Conclusions: EUS-GBD is a safe and effective long-term treatment for cholecystitis in non-surgical candidates. However, malignancy-associated cholecystitis carries a high risk of recurrence, warranting careful follow-up and individualized management. en-copyright= kn-copyright= en-aut-name=HaradaKei en-aut-sei=Harada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkimotoYutaka en-aut-sei=Akimoto en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HattoriNao en-aut-sei=Hattori en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Endoscopy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, National Organization Iwakuni Clinical Center kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Endoscopy, Okayama University Hospital, 2-5-1 Shikata-cho, Okayama 700-8558, Japan kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Endoscopy, Okayama University Hospital, 2-5-1 Shikata-cho, Okayama 700-8558, Japan kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=16 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=cholecystitis kn-keyword=cholecystitis en-keyword=drainage kn-keyword=drainage en-keyword=endosonography kn-keyword=endosonography en-keyword=gallbladder kn-keyword=gallbladder END start-ver=1.4 cd-journal=joma no-vol=367 cd-vols= no-issue= article-no= start-page=199724 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mycoviruses diversity in the black k?ji mold, Aspergillus luchuensis (section Nigri) isolated from liquor-production environments in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Some fungal species in the genus Aspergillus are economically important due to their role in the production of liquors and various foods; however, their viromes, which may affect their performance, remain unexplored. Therefore, this study examined the viromes of nine strains of Aspergillus luchuensis (section Nigri), the black k?ji mold used in the production of shochu (a traditional Japanese liquor) in Japan. It identified virus-like sequences related to alterna-, partiti-, curvula, botourmia-, narna-like, and umbra-like viruses. Some sequences appear to represent new variants (e.g., alterna- and gammapartitiviruses), while many others correspond to novel viral species within established or proposed mycoviral families. All A. luchuensis strains harbored multiple virus infections, with 2 to 7 viruses per strain. Three alternavirus strains with four-segmented double-stranded RNA (dsRNA) genomes were confirmed, along with minor variants co-present with the predominant strains. Notably, a gammapartitivirus appears to have two additional dsRNA genome segments, along with two satellite-like short dsRNA segments in some fungal isolates. Furthermore, at least five short RNAs (0.48?1.31 kb) were identified, three of which are possibly satellite-like RNAs associated with novel single-stranded RNA viruses (botourmia- and umbra-like viruses). These findings reveal the great diversity of mycoviruses in A. luchuensis populations and lay the foundation for further investigation into their impact on fungal phenotypes and liquor production. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NanajiMisaki en-aut-sei=Nanaji en-aut-mei=Misaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugaharaHitomi en-aut-sei=Sugahara en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FumihiroFujimori en-aut-sei=Fumihiro en-aut-mei=Fujimori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Tokyo Kasei University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Northwest A&F University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Tokyo Kasei University kn-affil= en-keyword=Aspergillus luchuensis kn-keyword=Aspergillus luchuensis en-keyword=Section Nigri kn-keyword=Section Nigri en-keyword=Mycovirus kn-keyword=Mycovirus en-keyword=RNA-seq kn-keyword=RNA-seq en-keyword=Virus population kn-keyword=Virus population en-keyword=Genome segment kn-keyword=Genome segment en-keyword=Fermentation kn-keyword=Fermentation en-keyword=Island kn-keyword=Island END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative study of Ni?CeO2 catalysts prepared by impregnation and coprecipitation for CO2 methanation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explores how synthesis methods affect the structure and CO2 methanation performance of Ni?CeO2 catalysts prepared by coprecipitation and impregnation under identical conditions. Coprecipitation generated particles below 100 nm with uniform elemental distribution, together with large bulk-like particles exhibiting locally concentrated Ni species, attributed to differences in hydroxide solubility. Impregnation, by contrast, produced very large particles (>?500 nm) with smaller particles attached, while maintaining relatively homogeneous elemental distribution. Coprecipitated catalysts showed slightly higher surface area and oxygen vacancy concentration, resulting in higher apparent turnover frequencies (TOFapp) below 300 °C due to enhanced CO2 adsorption and high Ni site density. However, at temperatures above 350 °C, impregnated catalysts displayed higher CH4 selectivity and TOFapp, indicating reduced kinetic limitations and more efficient active-site utilization. These results provide insights for rational design of efficient CO2 methanation catalysts. en-copyright= kn-copyright= en-aut-name=FukudaNobuko en-aut-sei=Fukuda en-aut-mei=Nobuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImanoShuichi en-aut-sei=Imano en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaharaNozomi en-aut-sei=Nakahara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=687 cd-vols= no-issue= article-no= start-page=120087 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phase diagram of Fe-C-S ternary system under planetary core conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-pressure, high-temperature experiments were conducted to investigate melting relations and phase assemblages in the Fe-C-S ternary system at 5 and 15 GPa, covering a temperature range of 1300?1900 K, conditions directly relevant to the Moon’s and Mercury’s cores. At 1300 K, the system is primarily governed by Fe-S eutectic melting, exhibiting notable complexity in the carbon-rich and sulfur-poor regions. With increasing temperature, the phase diagram simplifies: at 5 GPa and 1700 K, the Fe-Fe?C-FeS system features three regions (Fe+L, C + L, and L). Similar phase assemblages are observed at 15 GPa, with Fe7C3 and diamond replacing Fe3C and graphite, respectively. Extensive Fe+L, C + L, and L regions are observed at 1900 K.
For a Moon’s core composed of a Fe-C-S alloy, nearly pure Fe is the only viable inner core phase above 1700 K. Below this temperature, both Fe and Fe?C are potential solid inner core phases, depending on carbon content; a two-phase solid inner core is also theoretically possible. The inferred compositions of the outer core suggest densities of 6200?7300 kg/m?, with tighter constraints for models featuring an Fe?C core.
At Mercury-relevant pressures, either Fe or Fe?C? may form the solid inner core, again depending on carbon content. If the inner core is nearly pure Fe, the liquid outer core density ranges from 7300 to 7900 kg/m?. In both scenarios, a “snow” regime is plausible, though with distinct settling times. The ternary phase diagram indicates that Mercury is likely to develop a structurally layered inner core during secular cooling.

Despite these interesting features, a small number of samples (<80 events) and sparse seismic network observations prevented us from gaining an in-depth understanding of shallow moonquakes. In this study, by using the Apollo 17 gravimeter as a pseudo-seismometer, we extend the Apollo lunar seismic network and located a few shallow moonquakes more accurately. In addition, comparing the located shallow-moonquake epicenters with surface/subsurface geological features indicates that at least one event may be better explained by deep-seated faults within the crust. Along with a previous demonstration of low-frequency moonquakes, our analysis of high-frequency events shows that the Apollo 17 gravimeter can serve as a seismometer over a broader frequency range than previously considered. en-copyright= kn-copyright= en-aut-name=OnoderaKeisuke en-aut-sei=Onodera en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraTaichi en-aut-sei=Kawamura en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institut de Physique du Globe de Paris, Universit?

Identification of reliable biomarkers to evaluate LC pathophysiology is needed.
Objectives: To investigate whether serum S- and N-antibody titers against SARS-CoV-2 spike and nucleocapsid proteins reflect the clinical features of LC.
Methods: This retrospective observational study included patients diagnosed with Omicron variant-related LC who attended a post-COVID-19 outpatient clinic between July 2023 and November 2024 and provided informed consent for antibody testing.
Results: Among 275 patients (129 men and 146 women), 57 (21%) were unvaccinated. Median S- and N-antibody titers in vaccinated versus unvaccinated patients were 20,963 U/mL and 24.8 cut-off index (COI) versus 24 U/mL and 44.5 COI, respectively. S-antibody titers were associated with the number of vaccine doses received, whereas N-antibody titers correlated with disease severity during the acute phase of COVID-19 infection, with females having higher titers by multivariable analysis. N-antibody titers in unvaccinated patients with LC were negatively correlated with time interval from infection to clinic visit, with an estimated daily decline of 0.34% in measured N-antibody levels. Patients with LC having memory impairment had low S-antibody titers by multivariable logistic regression analysis, and low S-antibody levels were associated with reduced quality of life (QOL). Additionally, N-antibody titers positively correlated with lymphocyte counts and immunoglobulin levels.
Conclusion: Serum N-antibody titers reflect immune responses to COVID-19, although they are affected by gender differences and interval between infection and evaluation. Lower S-antibody titers were associated with brain fog symptoms and reduced QOL in patients with LC. en-copyright= kn-copyright= en-aut-name=KawaguchiMarina en-aut-sei=Kawaguchi en-aut-mei=Marina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsukiNobuyoshi en-aut-sei=Matsuki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FurukawaMasanori en-aut-sei=Furukawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HigashikageAkihito en-aut-sei=Higashikage en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=brain fog kn-keyword=brain fog en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=long COVID kn-keyword=long COVID en-keyword=Omicron variants kn-keyword=Omicron variants en-keyword=SARS-CoV-2 antibodies kn-keyword=SARS-CoV-2 antibodies END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e23328 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260418 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials en-subtitle= kn-subtitle= en-abstract= kn-abstract=With unique optical and physicochemical properties, carbon nanomaterials (CNMs), including carbon nanotubes, graphene-related materials, nanodiamonds, and carbon dots, are extensively explored as platforms for cancer diagnosis and treatment. However, in biofluids, CNMs spontaneously adsorb biomolecules to form an unpredictable corona, obstructing the implementation of their designed functions. In this review, we summarize how the intrinsic and acquired properties of CNMs affect protein corona formation, and the consequent biological and toxicological outcomes, as well as strategies to reshape the composition and structural organization of adsorbed proteins. This comprehensive knowledge will provide insights into developing CNMs with tailored corona and requested functions in cancer nanomedicine, advancing their translations into clinics. en-copyright= kn-copyright= en-aut-name=ZouYajuan en-aut-sei=Zou en-aut-mei=Yajuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HuYalei en-aut-sei=Hu en-aut-mei=Yalei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuJie en-aut-sei=Yu en-aut-mei=Jie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KomatsuNaoki en-aut-sei=Komatsu en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=CNRS, Immunology Immunopathology and Therapeutic Chemistry University of Strasbourg ISIS kn-affil= affil-num=3 en-affil=Graduate School of Human and Environmental Studies, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Human and Environmental Studies, Kyoto University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=carbondots kn-keyword=carbondots en-keyword=carbonnanotubes kn-keyword=carbonnanotubes en-keyword=graphene kn-keyword=graphene en-keyword=nanodiamonds kn-keyword=nanodiamonds en-keyword=proteins kn-keyword=proteins END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feasibility of Comprehensive Genomic Profiling for Biliary Tract Cancer Using Transpapillary Biopsy Samples: A Prospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Patients with biliary tract cancer (BTC) often have actionable mutations, and comprehensive genomic profiling (CGP) plays an important role. However, the feasibility of CGP using transpapillary biopsy (TPB) samples remains unclear.
Methods: Thirty patients with suspected BTC based on radiographic imaging were enrolled. Pre-analytical criteria for CGP suitability were based on the OncoGuide NCC Oncopanel System (NCCOP) and FoundationOne CDx (F1CDx). Each patient underwent six biopsies using an endoscopic introducer: five biopsy samples were preserved as formalin-fixed paraffin-embedded (FFPE) samples and one as a fresh frozen (FF) sample. DNA quality indicators were compared between the two groups.
Results: Malignancy was confirmed in 29 patients, and one had a benign biliary stricture. Suitability rate was 31% (9/29) for NCCOP and 3.4% (1/29) for F1CDx. Compared to FFPE samples, FF samples demonstrated significantly higher DNA concentration [ng/μL, interquartile range (IQR)], [0.34 (0.16?0.95) vs. 37.8 (11.6?67.6), p? Conclusions: Introducer-assisted multipass TPB may increase the rate of obtaining adequate CGP specimens, but its suitability remains limited and strongly panel dependent. Since FF samples have better DNA quality, establishing a system detailing their use is desirable.

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

In particular, determining the structure of the crust?mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to fully constrain it. To address this, we used seismic wave arrivals from impact events, which yield constraints on the crust at both the impact sites and the Apollo stations, to invert for local crustal thickness. Based on a series of assumed crust and mantle density models, we compared Moho depths inferred from global gravity recovery and interior laboratory gravity data with those from seismic observations. Although the gravity‐derived results broadly capture the overall Moho relief, local discrepancies remain, with differences reaching up to 10 km in the vicinity of the Apollo 17 Saturn IVB impact site. These results may reflect regional geological anomalies and highlight the importance of incorporating multiple seismically constrained crustal thickness estimates as anchors in gravity inversions. Using seven seismic anchor points and assuming an upper mantle velocity of Vp = 7.68 km/ s, an upper mantle density of 3,280 kg/m3, and a crustal density of 2,693 kg/m3, we obtain an average lunar crustal thickness of 43.6 ± 1.9 km. The findings also provide valuable guidance for future global 3D modeling of the Moon. en-copyright= kn-copyright= en-aut-name=ZhangXiang en-aut-sei=Zhang en-aut-mei=Xiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraTaichi en-aut-sei=Kawamura en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DrilleauM?lanie en-aut-sei=Drilleau en-aut-mei=M?lanie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Lognonn?Philippe en-aut-sei=Lognonn? en-aut-mei=Philippe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HenriSamuel en-aut-sei=Henri en-aut-mei=Samuel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=XuZongbo en-aut-sei=Xu en-aut-mei=Zongbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OnoderaKeisuke en-aut-sei=Onodera en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BodinThomas en-aut-sei=Bodin en-aut-mei=Thomas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Universit?

These processes are controlled by complex signaling networks in guard cells, in which calcium ions (Ca2+) act as a ubiquitous second messenger. Although stimulus-specific Ca2+ signatures have been well documented, how these signals are decoded into distinct physiological responses remains a central question in plant biology. Increasing evidence highlights calcium-dependent protein kinases (CDPKs) as key signal decoders in guard cell signaling. This mini-review summarizes recent advances in our understanding of how CDPKs perceive and translate Ca2+ fluctuations into stomatal responses. We focus on the roles of CDPKs in signaling pathways triggered by diverse stimuli, including phytohormones such as abscisic acid ABA, jasmonates, and salicylic acid, as well as biotic cues such as microbe- or pathogen-associated molecular patterns (MAMPs/PAMPs) and pathogen infection. We also discuss how gaseous signals and metabolic cues are integrated into CDPK-mediated pathways. In addition to their established role as downstream decoders of Ca2+ signals, emerging studies suggest that CDPKs can act upstream of Ca2+ oscillations and may also function through Ca2+-independent mechanisms. Together, these findings highlight the context-dependent and integrative roles of CDPKs in regulating stomatal behavior, contributing to plant fitness under fluctuating environmental conditions. en-copyright= kn-copyright= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Ca2+ signaling kn-keyword=Ca2+ signaling en-keyword=CDPK kn-keyword=CDPK en-keyword=Signal decoding kn-keyword=Signal decoding en-keyword=Stomata kn-keyword=Stomata END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=3 article-no= start-page=e70500 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early sedation intensity and psychological outcomes in critically ill adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Long-term psychological impairment is a major concern for intensive care unit (ICU) survivors. Early deep sedation during mechanical ventilation has been associated with poor short-term outcomes and mortality after ICU discharge; however, its relationship with psychological outcomes remains unclear.
Aim: To investigate sedation intensity during the first 24?h of mechanical ventilation and its association with psychological impairment 3 months after ICU discharge.
Study Design: This retrospective ancillary analysis of a single-centre cohort study was conducted in two general ICUs at a university hospital in Japan. Eligible patients stayed in the ICU for more than 48?h and received mechanical ventilation for more than 8?h. Sedation intensity was quantified using the Sedation Index (SI) and Agitation Index (AI) derived from Richmond Agitation-Sedation Scale scores during the first 24?h. Psychological impairment 3 months post-ICU discharge was assessed based on symptoms of post-traumatic stress, anxiety and depression. Associations were examined using hierarchical logistic regression.
Results: Among 130 participants, the median age was 64?years, and the median ventilation duration was 14?h. The median SI was 3.0; 47% had SI >?3, and 8.5% had AI >?0. Sedation intensity showed no significant association with psychological impairment (SI: adjusted odds ratio [OR] 0.87, 90% confidence interval [CI] 0.57?1.33, p?=?0.59; AI: adjusted OR 0.21, 90% CI 0.01?3.08, p?=?0.34). However, any agitation during the ICU stay was associated with psychological outcomes (adjusted OR 2.61, 90% CI 1.16?5.88, p?=?0.05).
Conclusions: This study did not identify a statistically significant association between early sedation intensity and psychological impairment 3 months after ICU discharge.
Relevance to Clinical Practice: Critical care nurses should carefully titrate sedation from the initiation of mechanical ventilation to avoid unnecessary deep sedation, considering sedation intensity over time, while actively assessing agitation and its underlying causes. en-copyright= kn-copyright= en-aut-name=IwataniMikiko en-aut-sei=Iwatani en-aut-mei=Mikiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University Hospital; Graduate School of Health Sciences, Doctoral Program, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=anxiety kn-keyword=anxiety en-keyword=depression kn-keyword=depression en-keyword=post-intensive care syndrome kn-keyword=post-intensive care syndrome en-keyword=post-traumatic stress disorder kn-keyword=post-traumatic stress disorder en-keyword=sedation intensity kn-keyword=sedation intensity END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue= article-no= start-page=2026010 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supplementation of 5-Aminolevulinic Acid Suppressed Body Weight Loss and Reduced Disease Severity During Eimeria tenella Infection in Broiler Chickens en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the effects of 5-aminolevulinic acid (5-ALA) supplementation in broiler chickens infected with Eimeria tenella. To assess these effects, chickens supplemented with 20 ppm 5-ALA (5-ALA group) were compared with non-supplemented controls (control group). Sporulated E. tenella oocysts (2.0 × 103 oocysts per animal) were administered orally to 2-week-old broiler chickens. Body weight was measured weekly, and fecal samples were collected daily from 4 to 15 days post-infection (dpi). Fecal oocyst shedding was quantified using the sucrose flotation method. Cecal tissues were collected at 5 dpi for histopathological analysis and lesion scoring. The animals in the 5-ALA group exhibited significantly greater weight gain and milder clinical signs than those in the control group. Fecal oocyst shedding was highest at 7 dpi in both groups; however, the 5-ALA group exhibited significantly lower oocyst output than the control group. The total number of fecal oocysts shed during the acute infection period was significantly lower in the 5-ALA group than in the control group. Histopathological analysis revealed that although both groups exhibited epithelial hyperplasia and E. tenella schizonts in the cecal submucosa, inflammatory cell infiltration, cecal tissue damage, and histological lesion scores were significantly lower in the 5-ALA group than in the control group. These results suggest that 5-ALA supplementation may mitigate the clinical, parasitological, and histological effects of E. tenella infection in broiler chickens. en-copyright= kn-copyright= en-aut-name=HanifTaqi Ahmad en-aut-sei=Hanif en-aut-mei=Taqi Ahmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsubayashiMakoto en-aut-sei=Matsubayashi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Veterinary Science, Graduate School of Veterinary Sciences, Osaka Metropolitan University kn-affil= affil-num=3 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=5-aminolevulinic acid kn-keyword=5-aminolevulinic acid en-keyword=avian coccidiosis kn-keyword=avian coccidiosis en-keyword=broilers kn-keyword=broilers END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=265 end-page=271 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Automatic Detection of Turning Over in Bed with Protection of Privacy Using Four Low-resolution Thermal Sensors to Support Nursing Care en-subtitle= kn-subtitle= en-abstract= kn-abstract=Turning over in bed, especially turning over at night, is a vital human unconscious behavior. Clinically, this movement disperses pressure between the body and bed, thus preventing bedsores. Several devices, such as acceleration and pressure sensors, can count turning overs automatically; however, they often require installation on the patients or in the bed. The simplest and noninvasive method to count turning overs is to record and count on video images, but this method cannot protect privacy. Images obtained using thermal sensors have been used to protect privacy; however, there are no reports of counting turning overs automatically using low-resolution sensors. We developed a novel device equipped with four low-resolution thermal sensors, with each sensor recording only an 8×8-pixel thermal image. The original data can protect patient privacy because the resolution is only ~28.8×28.8 cm per body, which is the lowest resolution compared to previous reports using thermal images. Using four sensors simultaneously enables us to collect sufficient data for automatic identification. We first used the bilinear interpolation method employed in a previous report to count turning overs; however, the results were unsatisfactory because turning overs produced extremely subtle changes in the original data compared with postural changes such as falls. After several attempts, we finally developed a unique identification program that interleaved all data from four sensors and then identified turning overs using residual neural network-18. Using the new system, the accuracy, recall, and precision of counting turning overs in bed improved to approximately 90% with an acceptable computation load in an experiment conducted on volunteers. This study demonstrated the feasibility of our device to count turning overs in clinical settings by the new identification program using four 8×8-pixel thermal images per frame, which have sufficiently low resolution to protect patient privacy. en-copyright= kn-copyright= en-aut-name=ChouJyun-Jhe en-aut-sei=Chou en-aut-mei=Jyun-Jhe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RaiKammei en-aut-sei=Rai en-aut-mei=Kammei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShihChi-Sheng en-aut-sei=Shih en-aut-mei=Chi-Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Computer Science and Information Engineering, National Taiwan University kn-affil= affil-num=2 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Graduate Institute of Networking and Multimedia, National Taiwan University kn-affil= en-keyword=turning overs kn-keyword=turning overs en-keyword=privacy kn-keyword=privacy en-keyword=thermal sensors kn-keyword=thermal sensors en-keyword=low-resolution kn-keyword=low-resolution en-keyword=ResNet kn-keyword=ResNet END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=e71853 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multi-Transcriptomic Analysis Reveals That EREG-Driven TME Crosstalk Defines Anti-EGFR Response in Colorectal Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sidedness influences colorectal cancer (CRC) prognosis and treatment response, yet the mechanism dictating differential EGFR inhibitor (EGFRI) sensitivity is unclear. This study investigated the tumor microenvironment (TME) in relation to EGFRI eligibility―clinically defined by factors such as tumor sidedness (e.g., left-sided), RAS/BRAF wild-type status, and microsatellite stability (MSS)―using integrated single-cell RNA sequencing (scRNA-seq), with bulk RNA-seq and spatial transcriptomics validation. We found cancer cell features reflected EGFRI eligibility more strongly than sidedness. EGFRI eligible tumors exhibited high Epiregulin (EREG) expression by cancer cells. Cell interaction analysis revealed a specific “EREG/EGFR/CSF axis” in EGFRI eligible CRC: EREG derived from cancer cell stimulates EGFR-expressing non-myCAF subtypes of cancer-associated fibroblasts (CAFs), which signal via CSF to M1/M2-like Tumor-Associated Macrophages/Monocytes (TAM/TAMo), potentially promoting M2 polarization. Spatial analysis confirmed the proximity of these interacting cell populations and localized EGFR pathway activation near cancer cells specifically in eligible tumors. This study provides a TME-centric view of EGFRI eligibility, identifying a key intercellular communication network driving differential responses. These findings suggest TME features could offer more precise patient stratification than sidedness alone, potentially improving CRC therapeutic strategies. en-copyright= kn-copyright= en-aut-name=TaniguchiAtsuki en-aut-sei=Taniguchi en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogiShohei en-aut-sei=Nogi en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YagiTomohiko en-aut-sei=Yagi en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell?cell interaction kn-keyword=cell?cell interaction en-keyword=colorectal cancer kn-keyword=colorectal cancer en-keyword=EGFR inhibitor eligibility kn-keyword=EGFR inhibitor eligibility en-keyword=Epiregulin (EREG) kn-keyword=Epiregulin (EREG) en-keyword=tumor microenvironment kn-keyword=tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=13650 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sex-related differences in blood concentrations and emergence profiles following total intravenous anesthesia with remimazolam and remifentanil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Remimazolam is a novel, short-acting benzodiazepine, which is characterized by rapid onset and quick recovery. The clinical efficacy and metabolism of many intravenous anesthetics are known to be influenced by sex; however, the effects of sex on the anesthetic efficacy and metabolism of remimazolam remain unclear. This prospective observational study examined sex-related differences in pharmacokinetics and emergence profiles after total intravenous anesthesia was induced with remimazolam and remifentanil in patients undergoing oral and maxillofacial surgery. Thirty-five American Society of Anesthesiologists Physical Status 1 adults (19 females, 16 males), aged 18?49 years, received standardized dosing based on their actual body weights. Serum remimazolam concentrations were measured at the end of administration and immediately before extubation using high-performance liquid chromatography. Although the emergence time did not differ significantly between the sexes, the mean emergence time of the females was approximately 80 s shorter. Serum remimazolam concentrations were significantly lower in females at both measurement time points (p? Methods Salmonella enterica isolates were identified by standard biochemical and serotyping. Antimicrobial susceptibility was tested by disk diffusion method and virulence genes were identified by PCR. The genetic relatedness of strains was determined by pulsed-field gel electrophoresis (PFGE) methods.
Results A total of 122 S. enterica isolates were identified and classified into 18 different serovars. S. Typhimurium (28.7%), S. Kentucky (22.1%), S. Enteritidis (13.9%), S. Typhi (5.7%) and S. Agona (5.7%) were identified as the common serovars. S. enterica infection was more often detected in adults (77.9%) than in children of 6?18 years old (11.4%) and Conclusions Cancer patients are at increased risk of morbidity due to secondary infections, like S. enterica. Continuous monitoring of antimicrobial resistance patterns and virulence gene profiles in S. enterica isolates from this vulnerable group is critical to guide clinical management and treatment strategies. en-copyright= kn-copyright= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BhattacharyaSanjay en-aut-sei=Bhattacharya en-aut-mei=Sanjay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GoelGaurav en-aut-sei=Goel en-aut-mei=Gaurav kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChatterjiSoumyadip en-aut-sei=Chatterji en-aut-mei=Soumyadip kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LewisMelissa Glenda en-aut-sei=Lewis en-aut-mei=Melissa Glenda kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR- NICED kn-affil= affil-num=2 en-affil=Tata Medical Center kn-affil= affil-num=3 en-affil=Tata Medical Center kn-affil= affil-num=4 en-affil=Tata Medical Center kn-affil= affil-num=5 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR- NICED kn-affil= affil-num=6 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases at ICMR- NICED kn-affil= affil-num=7 en-affil=Division of Biostatistics, ICMR - National Institute for Research in Bacterial Infections kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Division of Bacteriology, ICMR - National Institute for Research in Bacterial Infections kn-affil= affil-num=10 en-affil=Division of Bacteriology, ICMR - National Institute for Research in Bacterial Infections kn-affil= en-keyword=Salmonella enterica kn-keyword=Salmonella enterica en-keyword=Cancer kn-keyword=Cancer en-keyword=Virulence kn-keyword=Virulence en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=PFGE kn-keyword=PFGE END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=5 article-no= start-page=e00824-24 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250527 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sodium butyrate inhibits the expression of virulence factors in Vibrio cholerae by targeting ToxT protein en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cholera, a diarrheal disease caused by the gram-negative bacterium Vibrio cholerae, remains a global health threat in developing countries due to its high transmissibility and increased antibiotic resistance. There is a pressing need for alternative strategies, with an emphasis on anti-virulent approaches to alter the outcome of bacterial infections, given the increase in antimicrobial-resistant strains. V. cholerae causes cholera by secreting virulence factors in the intestinal epithelial cells. These virulence factors facilitate bacterial colonization and cholera toxin production during infection. Here, we demonstrate that sodium butyrate (SB), a small molecule, had no effect on bacterial viability but was effective in suppressing the virulence attributes of V. cholerae. The production of cholera toxin (CT) was significantly reduced in a standard V. cholerae El Tor strain and two clinical isolates when grown in the presence of SB. Analysis of mRNA and protein levels further revealed that SB reduced the expression of the ToxT-dependent virulence genes like tcpA and ctxAB. DNA-protein interaction assays, conducted at cellular (ChIP) and in vitro conditions (EMSA), indicated that SB weakens the binding between ToxT and its downstream promoter DNA, likely by blocking DNA binding. Furthermore, the anti-virulence efficacy of SB was confirmed in animal models. These findings suggest that SB could be developed as an anti-virulence agent against V. cholerae, serving as a potential alternative to conventional antibiotics or as an adjunctive therapy to combat cholera. en-copyright= kn-copyright= en-aut-name=KunduSushmita en-aut-sei=Kundu en-aut-mei=Sushmita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DasSuman en-aut-sei=Das en-aut-mei=Suman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaitraPriyanka en-aut-sei=Maitra en-aut-mei=Priyanka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HalderProlay en-aut-sei=Halder en-aut-mei=Prolay kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KoleyHemanta en-aut-sei=Koley en-aut-mei=Hemanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ChatterjeeNabendu Sekhar en-aut-sei=Chatterjee en-aut-mei=Nabendu Sekhar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=BhattacharyaSushmita en-aut-sei=Bhattacharya en-aut-mei=Sushmita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Biochemistry, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=2 en-affil=Division of Biochemistry, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=3 en-affil=Division of Biochemistry, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=4 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=5 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=6 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=7 en-affil=Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Division of Bacteriology, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=9 en-affil=Division of Biochemistry, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= affil-num=10 en-affil=Division of Biochemistry, ICMR-National Institute for Research in Bacterial Infections (Formerly ICMR-National Institute of Cholera and Enteric Diseases) kn-affil= en-keyword=sodium butyrate (SB) kn-keyword=sodium butyrate (SB) en-keyword=inhibitor kn-keyword=inhibitor en-keyword=pathogenesis kn-keyword=pathogenesis en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae en-keyword=ctxAB kn-keyword=ctxAB en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=toxin-coregulated pilus (TcpA) kn-keyword=toxin-coregulated pilus (TcpA) END start-ver=1.4 cd-journal=joma no-vol=211 cd-vols= no-issue= article-no= start-page=104882 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lease or sale: When a durable goods monopolist can choose supply chain openness en-subtitle= kn-subtitle= en-abstract= kn-abstract=We construct a two-period model of supply chain openness in a durable goods market with two marketing modes: leasing and selling. For a given marketing mode, at the beginning of the first period, an incumbent supplier and the downstream monopolist choose one of two trading modes: (i) a two-period exclusive supply chain, or (ii) an open supply chain, allowing the downstream monopolist to trade with an efficient supplier in the second period. We show that in the selling mode, the exclusive supply chain can arise if the incumbent supplier is highly efficient. In contrast, under the leasing mode, the exclusive supply chain never arises; instead, the open supply chain is always selected. Furthermore, when the downstream monopolist is allowed to endogenously choose the marketing mode before the first period, it opts for the selling mode if the incumbent supplier is relatively inefficient; otherwise, it selects the leasing mode. Regardless of the chosen marketing mode, the open supply chain always arises on the equilibrium path, implying that the recent advancement of ICT to enhance leasing may discourage the adoption of exclusive supply chains. en-copyright= kn-copyright= en-aut-name=KitamuraHiroshi en-aut-sei=Kitamura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsushimaNoriaki en-aut-sei=Matsushima en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoMisato en-aut-sei=Sato en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Economics, Kyoto Sangyo University kn-affil= affil-num=2 en-affil=Osaka School of International Public Policy, University of Osaka kn-affil= affil-num=3 en-affil=Faculty of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=Durable goods kn-keyword=Durable goods en-keyword=Exclusive supply chain kn-keyword=Exclusive supply chain en-keyword=Vertical relation kn-keyword=Vertical relation en-keyword=Selling versus leasing kn-keyword=Selling versus leasing END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=153 end-page=157 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=Revisiting Adrenal Crisis Triggered by Influenza Infection: Lessons from Two Fatal Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Adrenal crisis is a life-threatening endocrine emergency that can progress within hours despite a prior diagnosis and maintenance therapy.

Despite resuscitation and intravenous hydrocortisone, a fatal hypoxic-ischemic injury or multiorgan failure occurred. These cases highlight the fulminant course of an adrenal crisis and underscore the importance of early recognition, clinician awareness, prompt parenteral hydrocortisone administration, and reinforcement of education for patients, caregivers, and healthcare providers to improve preparedness and prevent avoidable deaths. en-copyright= kn-copyright= en-aut-name=UedaYoshiyuki en-aut-sei=Ueda en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=adrenal insufficiency kn-keyword=adrenal insufficiency en-keyword=cardiac arrest kn-keyword=cardiac arrest en-keyword=hydrocortisone kn-keyword=hydrocortisone en-keyword=influenza kn-keyword=influenza en-keyword=shock kn-keyword=shock END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=131 end-page=139 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=Impact of Proteinuria on Postoperative Complications Following Colorectal Cancer Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colorectal surgery is associated with a high incidence of postoperative complications regardless of the advances in surgical techniques and multidisciplinary treatment. Proteinuria is common in patients with malignancies, but few studies have investigated the association between preoperative proteinuria and patient prognoses, especially postoperative complications. We investigated the impact of proteinuria on patients undergoing colorectal surgery in a single-center, retrospective cohort study of 767 patients who underwent surgical resection for colorectal cancer between January 2016 and December 2022 at the National Hospital Organization Shikoku Cancer Center. Among them, 81 patients with preoperative proteinuria were compared with the control group of 686 patients without proteinuria. Our analyses revealed that the patients with proteinuria had malnutrition with a significantly lower prognostic nutritional index compared to the no-proteinuria control group (p<0.001). The proteinuria group had a significantly advanced tumor stage (p=0.005), experienced more bleeding during the surgery (p=0.002), and required more transfusions (p<0.001). Postoperative complications were significantly more frequent in the proteinuria group (p=0.03), thus demonstrating that proteinuria was independently associated with postoperative complications (p=0.045). Proteinuria in patients undergoing colorectal cancer surgery can therefore be considered a risk factor for postoperative complications. en-copyright= kn-copyright= en-aut-name=NakataShunsuke en-aut-sei=Nakata en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakatsuFumiaki en-aut-sei=Takatsu en-aut-mei=Fumiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MikuriyaYoshihiro en-aut-sei=Mikuriya en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakishitaTomokazu en-aut-sei=Kakishita en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HatoShinji en-aut-sei=Hato en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtaKoji en-aut-sei=Ohta en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobatakeTakaya en-aut-sei=Kobatake en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, National Hospital Organization Shikoku Cancer Center kn-affil= en-keyword=colorectal cancer kn-keyword=colorectal cancer en-keyword=surgery kn-keyword=surgery en-keyword=proteinuria kn-keyword=proteinuria en-keyword=complication kn-keyword=complication en-keyword=malnutrition kn-keyword=malnutrition END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=119 end-page=129 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=Mini-open Corpectomy and Posterior Spinal Fixation with Single-Position Surgery in Lateral Decubitus Position for Osteoporotic Thoracolumbar Vertebral Collapse in Elderly Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=We evaluated the clinical outcomes and limitations of anterior and posterior combined surgery with a mini-open corpectomy applying an expandable cage (Xcore?) and percutaneous pedicle screw (PPS) fixation using single-position surgery in the lateral decubitus position in patients aged > 75 years with thoracolumbar vertebral collapse. The cases of 30 consecutive patients who underwent this procedure and had ? 1-year follow-up were retrospectively analyzed. The mean operative time was 78.8 min and the estimated blood loss was 115.7 ml per level. The complications included adjacent junctional failure (n=9, 30%), deep venous thrombosis (n=3, 10%), delirium (n=3, 10%), pleural injury (n=2, 6%), screw backout (n=1, 3%) kidney injury (n=1, 3%), chylothorax (n=1, 3%), and wound dehiscence (n=1, 3%). Seven cases (23.3%) required reoperation. Local kyphosis showed significant improvement (p<0.05) that was maintained at the final follow-up. The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire and a visual analogue scale indicated significant improvement in all categories at the final follow-up (p<0.05). The use of mini-open corpectomy and posterior fixation with SPAPS can thus provide reliable radiological correction and good postoperative clinical outcomes even in patients aged > 75 years. However, a limitation of this procedure is the rate of reoperation (23.3%) for osteoporosis-related adjacent segment fracture and screw backout. en-copyright= kn-copyright= en-aut-name=IkumaHisanori en-aut-sei=Ikuma en-aut-mei=Hisanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiroseTomohiko en-aut-sei=Hirose en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Otsuka Orthopedic Clinic kn-affil= en-keyword=single postion surgery kn-keyword=single postion surgery en-keyword=osteoporotic vertebral collapse kn-keyword=osteoporotic vertebral collapse en-keyword=anterior and posterior combined surgery kn-keyword=anterior and posterior combined surgery en-keyword=minimum invasive surgery kn-keyword=minimum invasive surgery END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=109 end-page=117 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 Mixed-Methods Study on Changes in Interprofessional Education Attitudes and Fundamental Competencies: A Pre?Post Analysis of Clinical Training in Dietetic Students en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the effects of interprofessional education (IPE) on dietetics students during clinical training, focusing on changes in their attitudes toward IPE and their fundamental competencies. Eighty third-year female students (mean age, 21.0 years) at a Japanese women’s university participated. Self-administered surveys were conducted before and after clinical training to assess attitudes toward IPE using the Readiness for Interprofessional Learning Scale (RIPLS) and the Shakaijin Kisoryoku (SKL; Fundamental Competencies for Working Persons) scale. Quantitative data were analyzed using paired t-tests, chi-squared tests, and cluster analyses. Qualitative data from open-ended responses were analyzed thematically. RIPLS and SKL scores increased significantly, from 65.3 to 68.9, and from 28. 4 to 33. 2, respectively (p<0.001). All 12 SKL items showed significant improvement. In free responses, “initiative” (66 mentions), “communication” (10), and “execution” (8) were the most frequently cited as improved competencies. Cluster analysis identified three groups: increasing scores (n=25), high baseline (n=30), and minimal change (n=25). No significant correlation was found between changes in RIPLS and SKL scores (r=?0.108, p=0.355). IPE integrated into clinical training may enhance dietetics students’ attitudes toward interprofessional collaboration and contribute to the development of professional identity. Individualized, phased IPE implementation is recommended to accommodate differences in learner readiness. en-copyright= kn-copyright= en-aut-name=SonoiMika en-aut-sei=Sonoi en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SonoiNorihiro en-aut-sei=Sonoi en-aut-mei=Norihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoyamaYoko en-aut-sei=Koyama en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Foods and Human Nutrition, Faculty of Human Life Sciences, Notre Dame Seishin University kn-affil= affil-num=2 en-affil=Center for Education in Medicine and Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Foods and Human Nutrition, Faculty of Human Life Sciences, Notre Dame Seishin University kn-affil= en-keyword=interprofessional education kn-keyword=interprofessional education en-keyword=dietetics students kn-keyword=dietetics students en-keyword=clinical training kn-keyword=clinical training en-keyword=professional competencies kn-keyword=professional competencies en-keyword=transformative learning kn-keyword=transformative learning END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=99 end-page=107 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=Consistent Clinical Outcomes of Anteroinferior Minimally Invasive Plate Osteosynthesis for Midshaft Clavicle Fractures Across AO/OTA Fracture Types en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the performance of minimally invasive plate osteosynthesis (MIPO) via the anteroinferior approach is increasingly adopted for midshaft clavicle fractures, the influence of fracture morphology on clinical outcomes under a standardized protocol is unclear. We retrospectively analyzed the cases of 54 patients who underwent anteroinferior MIPO for an acute midshaft clavicle fracture (AO/OTA types B1, B2, B3) performed by a single surgeon across three affiliated institutions (2009-2022). We evaluated the clinical outcomes, i.e., the surgical time, incision length, radiographic union, reduction accuracy, range of motion, pain (visual analog scale [VAS]), and complications and compared them among the three AO/OTA subtypes. The mean incision length (3.4 cm) and surgical time (71-79 min) were similar among the groups (both p>0.2). All fractures achieved radiographic union at a mean of 3.5 months. Postoperative alignment and clavicular length were maintained (length reduction ?1.0±2.2 mm [B1], ?0.5±2.0 mm [B2], ?0.6±1.8 mm [B3]; p=0.825; angulation ?0.8±3.4°, ?1.1±3.1°, ?0.3±3.3°; p=0.888). At 3 months, shoulder elevation and abduction were 169°-175° (p=0.079) and 164°-175° (p=0.324). Pain was minimal (100-mm VAS: ?1 mm; p=0.782). One plate-fatigue failure occurred; no supraclavicular-nerve symptoms were recorded. Anteroinferior MIPO yielded consistent outcomes across AO/OTA types, with excellent union rates, functional recovery, and few complications, indicating that this technique is safe and reproducible for the surgical management of midshaft clavicle fractures. en-copyright= kn-copyright= en-aut-name=Nguyen Trung Thanh en-aut-sei=Nguyen Trung Thanh en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimamuraYasunori en-aut-sei=Shimamura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiharaTakeshi en-aut-sei=Ishihara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FurutaniTomoki en-aut-sei=Furutani en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShitozawaHisakazu en-aut-sei=Shitozawa en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki 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 Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kousei Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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, Kawasaki Medical School General Medical Center 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=clavicle fracture kn-keyword=clavicle fracture en-keyword=minimally invasive plate osteosynthesis kn-keyword=minimally invasive plate osteosynthesis en-keyword=anteroinferior plating kn-keyword=anteroinferior plating en-keyword=AO/OTA classification kn-keyword=AO/OTA classification END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=85 end-page=97 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=Effects of Nonsurgical Periodontal Treatment on Bacterial and Clinical Parameters in Down Syndrome Patients Based on 16S rRNA Gene Amplicon Sequencing en-subtitle= kn-subtitle= en-abstract= kn-abstract=Individuals with Down syndrome (DS) are more susceptible to periodontal disease; however, microbial changes following treatment remain insufficiently understood. This study evaluated the effects of nonsurgical periodontal therapy on clinical outcomes and oral microbiome dynamics in 6 patients with DS using 16S rRNA gene amplicon sequencing. Bacterial diversity, composition, network structure, and predicted functional pathways were analyzed using dental plaque samples. Bleeding on probing decreased significantly (p=0.047) after treatment, with a trend toward reduction in periodontal inflamed surface area (p=0.05). The abundance of Fusobacteria at the class level decreased significantly after treatment. The abundance of Mogibacterium timidum was higher in the pretreatment group than in the posttreatment group. M. timidum was positively correlated with Treponema denticola and associated with multiple bacterial taxa in the network during pretreatment. Predicted functional pathways related to aromatic compound degradation were more abundant in posttreatment samples than in pretreatment samples. An increase in the abundance of Fusobacterium and the positive correlation between T. denticola and M. timidum, together with their associations with other periodontal pathogens before treatment, may contribute to the development of periodontitis in individuals with DS. Nonsurgical periodontal therapy produces measurable clinical improvement and promotes microbial shifts in patients with DS. en-copyright= kn-copyright= en-aut-name=ShibaTakahiko en-aut-sei=Shiba en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakamoriMitsuhito en-aut-sei=Takamori en-aut-mei=Mitsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatagiriSayaka en-aut-sei=Katagiri en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiRyota en-aut-sei=Kobayashi en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawauchiAki en-aut-sei=Kawauchi en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhsugiYujin en-aut-sei=Ohsugi en-aut-mei=Yujin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LinPeiya en-aut-sei=Lin en-aut-mei=Peiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EgusaMasahiko en-aut-sei=Egusa en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IwataTakanori en-aut-sei=Iwata en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaShigeru en-aut-sei=Maeda en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Periodontology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Biology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=4 en-affil=Department of Periodontology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=6 en-affil=Department of Oral Biology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Department of Oral Biology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=The center for Special Needs Dentistry, Medical Development Field, Okayama University kn-affil= affil-num=10 en-affil=Department of Periodontology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=11 en-affil=Department of Dental Anesthesiology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= en-keyword=Down Syndrome kn-keyword=Down Syndrome en-keyword=16S rRNA Gene Amplicon Sequencing kn-keyword=16S rRNA Gene Amplicon Sequencing en-keyword=periodontitis kn-keyword=periodontitis en-keyword=nonsurgical periodontal treatment kn-keyword=nonsurgical periodontal treatment en-keyword=oral microbiome kn-keyword=oral microbiome END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=75 end-page=83 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=Involvement of ADAM12 in TGF-β1-Induced Proliferation of Rheumatoid Arthritis Synovial Fibroblasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=A disintegrin and metalloproteinase 12 (ADAM12) is known to be involved in chondrocyte proliferation and is upregulated in the synovial tissue of osteoarthritis (OA). However, the underlying mechanisms of ADAM12 on rheumatoid arthritis (RA) synovial cell proliferation remain unknown. Here, we investigated the role of ADAM12 in the proliferation of RA synovial fibroblasts (RASFs). The expression and localization of ADAM12 in RA synovial tissues were examined by immunohistochemistry and compared with OA and healthy control (HC) synovial tissues. The effect of inflammatory cytokines (TNF-α, TGF-β1, and PDGF-BB) on ADAM12 expression in RASFs from RA patients was examined by real-time RT-PCR. The effect of ADAM12 knock-down by ADAM12 siRNA and ADAM12 overexpression on cell proliferation of RASFs were examined by WST-1 assay. ADAM12 was identified predominantly in RA synovial tissue rather than OA and HC synovial tissues. Stimulation with TGF-β1 upregulated the expression of ADAM12 and cell proliferation of RASFs. ADAM12 siRNA suppressed TGF-β1-induced cell proliferation of RASFs, while ADAM12 overexpression promoted the cell proliferation of RASFs. These findings demonstrate that ADAM12 may have a key role in TGF-β1-induced cell proliferation of synovial fibroblasts in patients with RA. en-copyright= kn-copyright= en-aut-name=LinDeting en-aut-sei=Lin en-aut-mei=Deting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMasahito en-aut-sei=Watanabe en-aut-mei=Masahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaNoriaki en-aut-sei=Otsuka en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchikawaChinatsu en-aut-sei=Ichikawa en-aut-mei=Chinatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShimizuNoriyuki en-aut-sei=Shimizu en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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 Orthopaedic Surgery, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Muscat Orthopaedic Clinic kn-affil= affil-num=4 en-affil=Medical Information and Assistive Technology Development, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Medical Technology, Graduate School of Health Sciences, Okayama University 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= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Division of Chronic Pain Medicine and Division of Comprehensive Rheumatology, Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=synovial tissue kn-keyword=synovial tissue en-keyword=TGF-β1 kn-keyword=TGF-β1 en-keyword=ADAM12 kn-keyword=ADAM12 en-keyword=cell proliferation kn-keyword=cell proliferation END start-ver=1.4 cd-journal=joma no-vol=367 cd-vols= no-issue= article-no= start-page=199714 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=Virome of the fungi associated with mushroom dry bubble disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dry bubble disease, attributed to the filamentous fungus Lecanicillium fungicola (Cordycipitaceae) results in huge yield losses in mushroom (Agaricus bisporus) cultivation worldwide. The possibilities for controlling the disease using commercial fungicides are highly limited, and therefore, there is an increasing demand for novel, alternative means of pest management. Our research objective was the comprehensive examination of viruses in the causal agents of dry bubble disease, which may open up an avenue for its virocontrol in the future. Out of 57 fungal isolates obtained from dry bubble-affected A. bisporus crops in various countries, 47 (82%) were confirmed by ITS (Internal Transcribed Spacer) sequence analysis as L. fungicola. In addition, different members of the genera Akanthomyces and Simplicillium (7 and 3 isolates, respectively), yet unknown to cause dry bubble symptoms, have also been detected. Cellulose column chromatography revealed the presence of double-stranded (ds) RNA in seven L. fungicola and three Akanthomyces sp. isolates, suggesting viral infection. The ten dsRNA-positive and eight randomly selected dsRNA-negative fungal strains were subjected to rRNA-depletion high-throughput RNA-sequencing analysis. The presence of seven new viruses representing four new species in the established families, Partitiviridae, Polymycoviridae, Botourmiaviridae and the narna-like virus group, and three previously established/proposed species in the families Chrysoviridae and “Mycovirgaviridae” were confirmed. The impact of the detected and identified viruses on their host fungi, and their potential applicability for virocontrol purposes will be examined in the future. This study provides the first detailed report on viruses of mushroom pathogenic fungi. en-copyright= kn-copyright= en-aut-name=HatvaniL?r?nt en-aut-sei=Hatvani en-aut-mei=L?r?nt kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugaharaHitomi en-aut-sei=Sugahara en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShahiSabitree en-aut-sei=Shahi en-aut-mei=Sabitree kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbiangSarah Remi en-aut-sei=Ibiang en-aut-mei=Sarah Remi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Kocsub?S?ndor en-aut-sei=Kocsub? en-aut-mei=S?ndor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KartaliT?nde en-aut-sei=Kartali en-aut-mei=T?nde kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FitzpatrickDavid A. en-aut-sei=Fitzpatrick en-aut-mei=David A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=GroganHelen en-aut-sei=Grogan en-aut-mei=Helen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Department of Biotechnology and Microbiology, Faculty of Science and Informatics, University of Szeged kn-affil= affil-num=9 en-affil=Department of Biotechnology and Microbiology, Faculty of Science and Informatics, University of Szeged kn-affil= affil-num=10 en-affil=Genome Evolution Laboratory, Department of Biology, Maynooth University kn-affil= affil-num=11 en-affil=Teagasc Food Research Center, Horticulture Development Department kn-affil= affil-num=12 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Lecanicillium fungicola kn-keyword=Lecanicillium fungicola en-keyword=Agaricus bisporus kn-keyword=Agaricus bisporus en-keyword=Akanthomyces kn-keyword=Akanthomyces en-keyword=Simplicillium kn-keyword=Simplicillium en-keyword=dsRNA kn-keyword=dsRNA en-keyword=Myovirus kn-keyword=Myovirus en-keyword=Fungal virus kn-keyword=Fungal virus en-keyword=Mycovirgaviridae kn-keyword=Mycovirgaviridae en-keyword=Partitiviridae kn-keyword=Partitiviridae en-keyword=Polymycoviridae kn-keyword=Polymycoviridae en-keyword=Botourmiaviridae kn-keyword=Botourmiaviridae en-keyword=Splipalmiviridae kn-keyword=Splipalmiviridae en-keyword=Narna-like virus kn-keyword=Narna-like virus END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=3 article-no= start-page=101428 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=Short- and long-term outcomes of anti-thymocyte globulin-based regimen for acute antibody-mediated rejection after lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Antibody-mediated rejection (AMR) remains a major barrier to successful lung transplantation (LTx). Despite advances in donor-specific alloantibody (DSA) detection, effective treatments are limited, with current management largely empirical. Acute clinical AMR, marked by rapid graft dysfunction, demands urgent intervention. In Japan, where approved therapies for AMR were historically limited, rabbit anti-thymocyte globulin (rATG) has been adopted as a treatment option.
Methods: This retrospective study analyzed 11 patients who developed acute AMR within three months after LTx at Okayama University Hospital between 2013 and 2023. Diagnosis (ISHLT possible AMR) was based on acute graft dysfunction unresponsive to steroids, positive DSA, and exclusion of infection, without histological confirmation due to procedural risk. rATG (1.5 mg/kg/day for 7 days) was administered, along with intravenous immunoglobulin (IVIG), plasma exchange (PLEX), and rituximab when indicated. Outcomes included DSA clearance, clinical response, survival, and adverse events.
Results: Remission was achieved in 64% of patients, with 36% not requiring PLEX and 64% not receiving rituximab. Early rATG treatment correlated with favorable outcomes, whereas delayed therapy resulted in poorer responses. Six patients (55%) survived without chronic lung allograft dysfunction (CLAD) for over one year. Adverse events included cytomegalovirus infection (91%), bacterial pneumonia (36%), fungal infection (18%), and malignancy (18%).
Conclusions: rATG was effective for acute possible AMR management, particularly when initiated early. Some patients achieved remission without adjunct therapy, indicating rATG's potent immunosuppressive activity. However, frequent infectious complications emphasize the need for optimized dosing and further studies to validate its safety and long-term efficacy. en-copyright= kn-copyright= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniShinji en-aut-sei=Otani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=Anti-thymocyte globulin kn-keyword=Anti-thymocyte globulin en-keyword=Acute antibody-mediated rejection kn-keyword=Acute antibody-mediated rejection en-keyword=Treatment kn-keyword=Treatment en-keyword=Lung transplantation kn-keyword=Lung transplantation END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=14 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Solution-Processable Near-Infrared-Absorbing Dye: Thiophene-Substituted N-Phenylphenothiazine Radical Cations for Stable Thin Films en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a π-extended N-phenylphenothiazine dye bearing thiophene substituents, designed to address the practical compromise between long-wavelength near-infrared (NIR) absorption and the isolability of a stable radical cation state. The target compound was synthesized via Suzuki?Miyaura cross-coupling and exhibited good solubility in common organic solvents. Cyclic voltammetry in dichloromethane showed a reversible one-electron oxidation at E0 = 0.19 V vs. Fc/Fc+. Chemical oxidation afforded the corresponding radical cation, which showed an intense NIR absorption maximum at 910 nm. DFT calculations support thiophene-induced narrowing of the HOMO?SOMO gap and predict a pronounced bathochromic shift of the main absorption band. The radical cation was isolated as a stable PF6? salt and readily processed into spin-coated films, which retained strong NIR absorption and remained stable for months under ambient conditions. en-copyright= kn-copyright= en-aut-name=YanoMasafumi en-aut-sei=Yano en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiKengo en-aut-sei=Sakai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaMinami en-aut-sei=Ueda en-aut-mei=Minami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsudoKoichi en-aut-sei=Mitsudo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashiwagiYukiyasu en-aut-sei=Kashiwagi en-aut-mei=Yukiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Chemistry, Material and Bioengineering, Kansai University kn-affil= affil-num=2 en-affil=Faculty of Chemistry, Material and Bioengineering, Kansai University kn-affil= affil-num=3 en-affil=Faculty of Chemistry, Material and Bioengineering, Kansai University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Osaka Research Institute of Industrial Science and Technology kn-affil= en-keyword=N-phenylphenothiazine kn-keyword=N-phenylphenothiazine en-keyword=radical cation kn-keyword=radical cation en-keyword=thiophene substitution kn-keyword=thiophene substitution en-keyword=near-infrared absorption kn-keyword=near-infrared absorption en-keyword=stability in solid state kn-keyword=stability in solid state END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=5942 end-page=5953 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=Transverse- and Axial-Flux Permanent Magnet Machine With C-Type SMC Stator: A Solution for Ultra-Flat Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=This article proposes a novel transverse- and axial-flux permanent magnet machine (T-AFPM) using a C-type stator core for reducing system size via an ultra-flat shape. With an axial length of only 19.7 mm, this ultra-flat shape contributes markedly to reducing system size in industrial applications such as water pumps. In general, AFPMs are suitable for a flat shape because of their high torque density with a short axial length. However, it is difficult to use conventional AFPMs to achieve an ultra-flat shape because of structural problems and insufficient performance. By contrast, the proposed T-AFPM achieves a highly manufacturable structure, high efficiency, and the required output power despite its extremely short axial length. Herein, the T-AFPM is compared with conventional AFPMs with various configurations by means of three-dimensional finite-element analysis, and experiments on a T-AFPM prototype are reported. From the simulation and experimental results, the proposed T-AFPM shows high efficiency (IE5 class), the required output power, and suitable structural properties for an ultra-flat shape. en-copyright= kn-copyright= en-aut-name=TsunataRen en-aut-sei=Tsunata en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoMasatsugu en-aut-sei=Takemoto en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiJun en-aut-sei=Imai en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoTatsuya en-aut-sei=Saito en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UenoTomoyuki en-aut-sei=Ueno en-aut-mei=Tomoyuki 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 Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Sumitomo Electric Sintered Alloy Ltd. kn-affil= affil-num=5 en-affil=Sumitomo Electric Sintered Alloy Ltd. kn-affil= en-keyword=Axial-flux machine kn-keyword=Axial-flux machine en-keyword=coreless rotor structure kn-keyword=coreless rotor structure en-keyword=C-shaped core kn-keyword=C-shaped core en-keyword=efficiency (IE5 class) kn-keyword=efficiency (IE5 class) en-keyword=permanent magnet synchronous machine (PMSM) kn-keyword=permanent magnet synchronous machine (PMSM) en-keyword=short axial length kn-keyword=short axial length en-keyword=soft magnetic composite (SMC) kn-keyword=soft magnetic composite (SMC) en-keyword=transverse-flux machine kn-keyword=transverse-flux machine en-keyword=ultra-flat shape kn-keyword=ultra-flat shape END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=8 article-no= start-page=e70175 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemical Synthesis of Benzo[b]Phosphole Oxides via Dehydrogenative Annulation Using 1,4-Diazabicyclo [2.2.2]Octane as a Mediator en-subtitle= kn-subtitle= en-abstract= kn-abstract=The electrochemical intermolecular annulation of diarylphosphine oxides with alkynes for the synthesis of benzo[b]phosphole oxides has been reported. The reaction proceeded under transition-metal- and oxidant-free conditions via indirect electrolysis, using 1,4-diazabicyclo[2.2.2]octane as a mediator. High-surface-area carbon electrodes, such as carbon felt and reticulated vitreous carbon, are essential for this reaction. Several diarylphosphine oxides and alkynes were applied to electrochemical annulation, and the corresponding benzo[b]phosphole oxides were obtained. Mechanistic studies suggested that the reaction proceeds via radical intermediates generated through multiple pathways. en-copyright= kn-copyright= en-aut-name=MitsudoKoichi en-aut-sei=Mitsudo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KinjoSakura en-aut-sei=Kinjo en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkumuraYasuyuki en-aut-sei=Okumura en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoEisuke en-aut-sei=Sato en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoRiki en-aut-sei=Kato en-aut-mei=Riki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugaSeiji en-aut-sei=Suga en-aut-mei=Seiji 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=annulation kn-keyword=annulation en-keyword=benzophosphole oxide kn-keyword=benzophosphole oxide en-keyword=electrochemistry kn-keyword=electrochemistry en-keyword=hydrogen atom transfer kn-keyword=hydrogen atom transfer en-keyword=radical cyclization kn-keyword=radical cyclization END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=e70251 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=Muscle Atrophy-Related Adverse Events of Antidiabetic Drug Classes: A Pharmacovigilance Analysis Using VigiBase Data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Diabetes mellitus?a chronic metabolic disorder associated with an increased risk of muscle atrophy?can significantly impact patients' quality of life and overall health outcomes. While antidiabetic medications are crucial for managing blood glucose levels, some have been linked to muscle-related adverse events, potentially exacerbating the already elevated risk of muscle deterioration in diabetic patients. However, a comprehensive analysis of muscle atrophy-related adverse events across different classes of antidiabetic drugs has been lacking. Therefore, this study investigates the profile of muscle atrophy-related adverse events across major antidiabetic drug classes using the World Health Organization's (WHO's) Individual Case Safety Reports database.
Methods: A pharmacovigilance analysis was conducted using data from VigiBase, the WHO's global reporting database, from 1968 to September 2025. The study examined adverse event signals related to muscle atrophy, sarcopenia, muscular weakness and motor function decline for nine classes of antidiabetic medications. Reporting odds ratios (RORs) were calculated to assess signal detection, and co-occurrence patterns of adverse events were analysed.
Results: Among 41?551?306 adverse event reports, 2?095?847 were related to antidiabetic medications. Safety signals for muscle atrophy were detected with sulfonylureas (ROR: 1.2, 95% CI: 1.01?1.43, p?=?0.042), GLP-1 analogues (ROR: 1.2, 95% CI: 1.02?1.41, p?=?0.031) and SGLT2 inhibitors (ROR: 1.5, 95% CI: 1.19?1.78, p? Conclusions: These findings indicate notable differences in the profiles of muscle atrophy?related adverse events among major classes of antidiabetic drugs, suggesting that drug selection may influence the risk of muscle function decline in patients. Clinicians should consider these safety profiles when prescribing antidiabetic therapies; however, causal relationships cannot be inferred solely from pharmacovigilance data. Further studies are warranted to establish causality between antidiabetic drug use and muscle-related adverse events and to elucidate the underlying mechanisms. en-copyright= kn-copyright= en-aut-name=UetaShiho en-aut-sei=Ueta en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=IshidaTomoaki en-aut-sei=Ishida en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataNaohiro en-aut-sei=Iwata en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=MiyataKoji en-aut-sei=Miyata en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= en-aut-name=ChumaMasayuki en-aut-sei=Chuma en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=Izawa‐IshizawaYuki en-aut-sei=Izawa‐Ishizawa en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 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=15 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=2 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=8 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=10 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Hospital Pharmacy and Pharmacology, Asahikawa Medical University kn-affil= affil-num=13 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= affil-num=14 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Clinical Pharmacology and Therapeutics, University of Tokushima Graduate School of Biomedical Sciences kn-affil= en-keyword=antidiabetic drug kn-keyword=antidiabetic drug en-keyword=muscle atrophy kn-keyword=muscle atrophy en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=VigiBase kn-keyword=VigiBase 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=20260407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ROWVA: A Structure-Based Metric for Predicting the Pathogenicity of Protein Variants Using Alphafold2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=p53, an important tumor suppressor protein, functions as a tetramer. Therefore, malignant variants in the tetramer-forming domain increase the likelihood of p53 dysfunction. Recent developments in genome analysis technology have expanded our understanding of malignant variants. However, variants of uncertain significance are also being increasingly identified. Hence, methods to assess the pathogenicity of these variants are required. In this study, we aimed to examine whether AlphaFold2 can be used to evaluate the functional impacts of p53 variants based on predicted three-dimensional (3D) structural information. For each variant present in datasets of p53 functional score, we performed 3D structural prediction using AlphaFold2. We analyzed the correlations among multiple AlphaFold2-derived scores to predict functional scores, such as protein stability and pathogenicity labels, for each dataset. The root-mean-square deviation obtained by comparing the 3D structures predicted by AlphaFold2 for the wild-type and variant structures showed a high correlation with each functional score. Overall, these findings indicate that AlphaFold2 can be used to evaluate variants. en-copyright= kn-copyright= en-aut-name=FurutaniTaiki en-aut-sei=Furutani en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NagamiHiroki en-aut-sei=Nagami en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanafusaHiroko en-aut-sei=Hanafusa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=NakatochiMasahiro en-aut-sei=Nakatochi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Public Health Informatics Unit, Department of Integrated Health Sciences, Nagoya University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Pharmacology, Graduate School of Medicine, Dentistry & Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pharmacology, Graduate School of Medicine, Dentistry & Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pharmacology, Graduate School of Medicine, Dentistry & Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacology, Graduate School of Medicine, Dentistry & Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pharmacology, Graduate School of Medicine, Dentistry & Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Public Health Informatics Unit, Department of Integrated Health Sciences, Nagoya University Graduate School of Medicine kn-affil= en-keyword=3D protein structural prediction kn-keyword=3D protein structural prediction en-keyword=AlphaFold2 kn-keyword=AlphaFold2 en-keyword=p53 kn-keyword=p53 en-keyword=tumor suppressor kn-keyword=tumor suppressor en-keyword=variants of uncertain significance kn-keyword=variants of uncertain significance END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=5 article-no= start-page=2741 end-page=2748 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global trends in systemic sclerosis-related mortality, 2001?2023: an epidemiological analysis using World Health Organization mortality data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives This study aimed to evaluate the global trends in systemic sclerosis (SSc)-related mortality by age, sex, and geographic region. SSc is a multisystem autoimmune disease characterized by tissue fibrosis, vascular dysfunction, and multi-organ involvement, which is associated with a high mortality risk.
Methods Using the World Health Organization Mortality Database, we examined trends in SSc-related crude mortality rates (SSc-CRs) and age-standardized mortality rates (SSc-ASMR) per 1,000,000 population from 2001 to 2023. Locally weighted regression was applied to visualize long-term patterns, and Joinpoint regression was used to assess the national trends from 2010 to 2023.
Results Across 74 countries, 85,291 SSc-related deaths were reported, with 79.41% occurring in females. The SSc-CR steadily increased from 1.97 (95% confidence interval [CI]: 1.71?2.23) in 2001 to 2.34 (95% CI: 2.01?2.68) in 2023, while the SSc-ASMR decreased from 1.58 (95% CI: 1.42?1.74) to 1.29 (95% CI: 1.08?1.50), respectively. Regionally, mortality was the highest in the Western Pacific region and declined in the Americas and Europe, with temporal fluctuations. The SSc-ASMR was highest in countries with a middle sociodemographic index (SDI).
Conclusions While overall age-standardized mortality from SSc has declined in many regions, disparities persist. These results underscore the importance of sustaining research and enhancing disease awareness, as well as developing strategies to reduce mortality in high-risk populations and regions. en-copyright= kn-copyright= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LescanoJudah Israel Ong en-aut-sei=Lescano en-aut-mei=Judah Israel Ong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMichio en-aut-sei=Yamamoto en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Haematology and Oncology, Mayo Clinic, Rochester kn-affil= affil-num=3 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Human Sciences, The University of Osaka kn-affil= affil-num=9 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= en-keyword=Age-standardized mortality rate kn-keyword=Age-standardized mortality rate en-keyword=Global health kn-keyword=Global health en-keyword=Mortality trends kn-keyword=Mortality trends en-keyword=Sociodemographic index kn-keyword=Sociodemographic index en-keyword=Systemic sclerosis kn-keyword=Systemic sclerosis 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=20260409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rice EMF3 Alleles Adjust Flower Opening Time to Enhance the Seed Setting Rate Under High Temperature Stress en-subtitle= kn-subtitle= en-abstract= kn-abstract=To safeguard global food security against rapid population growth and a warming world, the effective genetic improvement of cereals is imperative. Flower opening time (FOT) critically affects the seed setting rate. In this study, we identified a gene, EARLY-MORNING FLOWERING 3 (EMF3), in which single-nucleotide substitutions strongly modulate FOT in rice in a semi-dominant manner, resulting in wide variation in FOT from earlier to later FOT than the wild-type. EMF3 knock-out mutants showed significantly reduced FOT synchrony and disrupted anther dehiscence, leading to fertilisation failure. EMF3 encodes a plasma membrane-localised polypeptide of 723 amino acids with an armadillo repeat fold and four transmembrane segments. Furthermore, EMF3 is specifically expressed in the anthers starting from nighttime on the day of flowering, with substantial impacts on the transcriptomes of both anther and lodicule, which suggested an exclusive role of EMF3 in flowering events. Modifying EMF3 alleles of O. sativa enabled the adjustment of FOT among Oryza species and subspecies, potentially facilitating cross-fertilisation by overcoming one of the major challenges of inter-specific hybridisation to exploit heterosis. Introducing the EMF3 alleles with the earlier FOT into popular rice cultivars resulted in flowering at an earlier time of day when the temperature was cooler, efficiently increasing seed setting rate under heat stress. This discovery unveils the novel mechanism of anther control of flower opening time through the EMF3 gene, while also enabling the use of EMF3 alleles in breeding strategies for efficient fertilisation for increasing hybrid rice seed production and mitigating future heat-stress damage at flowering. en-copyright= kn-copyright= en-aut-name=IshizakiTakuma en-aut-sei=Ishizaki

the periodic superradiance observed in an Er:YSO crystal. First, we construct a model based on the Maxwell-Bloch equations for a reduced level system, a pair of superradiance states, and a population reservoir state. Analysis of the eigenvalues of the linearized differential equations shows that periodic superradiance can be realized only for certain parameters. We also derive two-variable equations consisting of the coherence and population difference between the two superradiance states, which contain the essential feature of the periodic superradiance. The two-variable equations clarify the mathematical structure of this periodic phenomenon and give analytical forms of the period, pulse duration, and number of emitted photons. Our model successfully reproduces the periodic behavior, but the actual experimental parameters are found to be outside the parameter region for the periodic superradiance. This result implies that some other mechanism(s) is (are) required. As one example, assuming that the field decay rate varies with the electric field, the periodic superradiance can be reproduced even under the actual experimental conditions. en-copyright= kn-copyright= en-aut-name=HaraHideaki en-aut-sei=Hara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HanJunseok en-aut-sei=Han en-aut-mei=Junseok kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmotoRiku en-aut-sei=Omoto en-aut-mei=Riku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ImaiYasutaka en-aut-sei=Imai en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimiAkihiro en-aut-sei=Yoshimi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraKoji en-aut-sei=Yoshimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshimuraMotohiko en-aut-sei=Yoshimura en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasaoNoboru en-aut-sei=Sasao en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=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= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=11550 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pseudohypoxia induced by iron chelators preserves working memory performance in aged mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pseudohypoxia refers to a physiological condition wherein hypoxia-inducible factor (HIF) is pharmacologically upregulated under normoxia, thereby modulating immune responses. We hypothesized that pseudohypoxia, induced by iron chelators, may similarly potentiate systemic immune responses in aged mice, concurrently triggering neuro-regenerative signaling pathways and enhancing cognitive performance. In this study, aged mice (43?48 weeks old) were orally administered two iron chelators, Super Polyphenol 10 (SP10) or Roxadustat, to induce a pseudohypoxia. An 8-week oral regimen of SP10 and Roxadustat significantly preserved working memory, as assessed by the Y-maze test (YMT). White blood cell counts and hippocampal volume, as assessed by magnetic resonance imaging (MRI), were elevated in the treatment groups relative to controls. Pseudohypoxia induced by SP10 tended to enhance neuro-regenerative signaling, specifically involving the Tau and JNK pathways, and potentially modulated Doublecortin (DCX) expression, although statistical significance was limited by sample size. Importantly, inflammatory markers, such as ionized calcium-binding adapter molecule 1 (Iba1) and glial fibrillary acidic protein (GFAP), were not elevated by treatment. Collectively, these findings suggest that pseudohypoxia induced by iron chelators preserves working memory performance accompanied by leukocytosis, without concomitant neuroinflammation. en-copyright= kn-copyright= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwasakiYoshiaki en-aut-sei=Iwasaki en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KasaiTomonari en-aut-sei=Kasai en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KomakiShiho en-aut-sei=Komaki en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HamadaYusuke en-aut-sei=Hamada en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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=Health Service Section, Environment Health & Safety Intelligence Department, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Energy, Graduate School of Engineering, Nagoya University kn-affil= affil-num=4 en-affil=Department of Neurology, Graduate School of 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=Hypoxia-inducible factor kn-keyword=Hypoxia-inducible factor en-keyword=Working memory kn-keyword=Working memory en-keyword=Hippocampus kn-keyword=Hippocampus en-keyword=Iron kn-keyword=Iron END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=4 article-no= start-page=1769 end-page=1784 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=P53-armed Oncolytic Adenovirus Enhances the Efficacy of PD-1 Blockade in Neuroblastoma by Inducing Immunogenic Cell Death en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Neuroblastoma (NB) is a primary malignant tumor of the peripheral sympathetic nervous system. Although immunotherapy with immune checkpoint inhibitors (ICIs) targeting programmed cell death 1 (PD-1)/PD ligand 1 (PD-L1) has emerged as novel antitumor therapy, high-risk NB tumors are refractory to ICI therapy. Oncolytic virotherapy is expected to potentiate the antitumor immune response by inducing immunogenic cell death (ICD). In the present study, we assessed the therapeutic potential of OBP-301 and OBP-702, telomerase-specific oncolytic adenoviruses, for the induction of ICD and combined effect with PD-1 blockade against NB cells.
Materials and Methods: The cytopathic activity of OBP-301 and OBP-702 was assessed using three human MYCN-amplified NB cell lines (IMR-32, LA-N-5, and NB-1) and a murine non-MYCN-amplified NB cell line (Neuro-2a). Virus-mediated antitumor effect was assessed by analyzing cell viability, secretion of extracellular adenosine triphosphate (ATP) and high-mobility group box protein B1 (HMGB1), apoptosis, autophagy, and PD-L1 levels. A subcutaneous Neuro-2a tumor model was used to evaluate the in vivo antitumor effect of combination therapy with OBP-702 and anti-PD-1 antibody.
Results: OBP-702 exhibited stronger cytopathic activity, inducing ICD with secretion of ATP and HMGB1, compared to OBP-301 in human and murine NB cells. OBP-301 and OBP-702 increased apoptosis, autophagy, and PD-L1 expression in murine NB cells. Moreover, OBP-702 significantly prolonged the survival of tumor-bearing mice compared to monotherapy with PD-1 blockade.
Conclusion: OBP-702 is a promising antitumor strategy to promote the antitumor effect of ICIs by inducing ICD against NB tumors. en-copyright= kn-copyright= en-aut-name=TANIMORIMICHI en-aut-sei=TANI en-aut-mei=MORIMICHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TAZAWAHIROSHI en-aut-sei=TAZAWA en-aut-mei=HIROSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TANIMOTOTERUTAKA en-aut-sei=TANIMOTO en-aut-mei=TERUTAKA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NOUSOHIROSHI en-aut-sei=NOUSO en-aut-mei=HIROSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WATANABEHINAKO en-aut-sei=WATANABE en-aut-mei=HINAKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OYAMATAKANORI en-aut-sei=OYAMA en-aut-mei=TAKANORI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=URATAYASUO en-aut-sei=URATA en-aut-mei=YASUO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KAGAWASHUNSUKE en-aut-sei=KAGAWA en-aut-mei=SHUNSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NODATAKUO en-aut-sei=NODA en-aut-mei=TAKUO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KURODASHINJI en-aut-sei=KURODA en-aut-mei=SHINJI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FUJIWARATOSHIYOSHI en-aut-sei=FUJIWARA en-aut-mei=TOSHIYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatric Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatric Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatric Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatric Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Oncolys BioPharma, Inc. kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Pediatric Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Neuroblastoma kn-keyword=Neuroblastoma en-keyword=oncolytic adenovirus kn-keyword=oncolytic adenovirus en-keyword=p53 kn-keyword=p53 en-keyword=immunogenic cell death kn-keyword=immunogenic cell death en-keyword=PD-1 kn-keyword=PD-1 END start-ver=1.4 cd-journal=joma no-vol=264 cd-vols= no-issue= article-no= start-page=128798 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improving thermal stability of a microcavity emitter for utilization under atmospheric environment en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the development of micro-fabrication technology, various metamaterials with controlled emission spectra have been proposed as thermal emitters. However, general metamaterials have a risk of deformations and degradation at high temperatures in atmospheric conditions, which is inconvenient for use as a thermal emitter. In this study, we propose a concept to enhance the thermal durability of microcavity-type metamaterials. Although typical microcavities are entirely composed of metal to excite the resonance of electromagnetic waves, we assessed the feasibility of a microcavity consisting of silicon with minimal metal coatings. While usual metals are oxidized at high temperatures, gold is rarely oxidized due to its chemical stability. However, the gold layer deposited on the Si substrate has the potential to melt below 400 °C due to the formation of an Au-Si eutectic alloy, which has a much lower melting point than pure gold. Therefore, we focused on the gold-tungsten bilayer as a suitable metal coating for the silicon microcavity, thereby preventing oxidation and melting that would otherwise influence the emission spectra of the thermal emitter. The numerical analysis ensured that the proposed microcavity exhibited electromagnetic resonance, similar to that of a microcavity entirely composed of metal, unless the metal coating was too thin. The fabricated microcavity with the gold-tungsten coating also exhibited a thermal emission within a limited wavelength range, due to the microcavity resonance. Moreover, the heating experiment revealed that the microcavity with a gold-tungsten coating maintained its emissivity even when heated to 400 °C, which is higher than the oxidation point of tungsten and the melting point of the Au-Si eutectic alloy. Consequently, the gold-tungsten coating would be a reasonable approach to improve the stability of the microcavity-type metamaterial at high temperatures under oxidative conditions. en-copyright= kn-copyright= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorishigeShota en-aut-sei=Morishige en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoTaiyo en-aut-sei=Sato en-aut-mei=Taiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaYutaka en-aut-sei=Yamada en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoribeAkihiko en-aut-sei=Horibe en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Metamaterial kn-keyword=Metamaterial en-keyword=Microcavity emitter kn-keyword=Microcavity emitter en-keyword=Emissivity spectrum kn-keyword=Emissivity spectrum en-keyword=Thermal stability kn-keyword=Thermal stability en-keyword=Tungsten oxidation kn-keyword=Tungsten oxidation en-keyword=Eutectic melting kn-keyword=Eutectic melting END start-ver=1.4 cd-journal=joma no-vol=220 cd-vols= no-issue=3 article-no= start-page=29 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knot surgered elliptic surfaces without 1- and 3-handles for a (2, 2h + 1)-torus knot en-subtitle= kn-subtitle= en-abstract= kn-abstract=For any positive integers h and n, we show that a knot surgered elliptic surface E(n)T(2,2h+1) for a (2, 2h + 1)-torus knot T (2, 2h + 1) admits a handle decomposition without 1- and 3-handles using a Kirby diagram derived from a Lefschetz fibration on it.

The geological complexity of the moon's surface suggests significant cyclic tidal deformation, likely leading to the fracturing of the ice shell. Considering realistic source locations and fault geometries, we assess whether a vertical short-period seismometer can detect body waves from a Mw 4.0 icequake. Signal-to-noise ratios are evaluated by comparing the high-frequency content with the expected background noise and instrument capabilities for several ice attenuation scenarios and 1D interior models. Our results indicate that the high-frequency content (?1Hz) of Mw?4.0 tidal-induced icequakes is likely undetectable under the most unfavorable attenuation scenarios and atmospheric conditions. However, seismic signals in the 0.5?1 Hz band?where P wave reflections dominate?may still be observable for events occurring in potential seismically active regions at ?800?1,000 km from the Dragonfly's landing site. These signals could provide constraints on the thickness of Titan's outer ice shell, provided that intrinsic attenuation is low and environmental conditions are favorable. en-copyright= kn-copyright= en-aut-name=DelaroqueL. en-aut-sei=Delaroque en-aut-mei=L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraT. en-aut-sei=Kawamura en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LucasA. en-aut-sei=Lucas en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RodriguezS. en-aut-sei=Rodriguez en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoderaK. en-aut-sei=Onodera en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiraishiH. en-aut-sei=Shiraishi en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaR. en-aut-sei=Yamada en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaS. en-aut-sei=Tanaka en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=PanningM.

This study investigated OCT4-PG1 expression, translational control, and its role in endometrial cancer and stem cell regulation. Quantitative analyses revealed that elevated OCT4A, but not OCT4-PG1, expression correlated with clinical risk factors associated with poor prognosis in patients with endometrial cancer. OCT4-PG1 is under strong translational suppression mediated by its untranslated region and does not function as a protein under normal conditions. Instead, it acts as a non-coding RNA that suppresses OCT4A translation. Structural analyses showed that a single amino acid deletion (Gln259) destabilizes the OCT4-PG1 protein, thereby preventing its tumorigenic and transcriptional functions. Nevertheless, OCT4-PG1 forms heterodimers with OCT4A or SOX2, enhancing the regulatory activity of OCT4A. These findings highlight the regulatory role of pseudogenes in cancer and stem cell biology, with implications for therapies targeting OCT4A-related pathways. en-copyright= kn-copyright= en-aut-name=IrieKyohei en-aut-sei=Irie en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakaMitsuko en-aut-sei=Kosaka en-aut-mei=Mitsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizunoNobuhiko en-aut-sei=Mizuno en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakataniYoshimasa en-aut-sei=Nakatani en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OoSandi Myat Noe en-aut-sei=Oo en-aut-mei=Sandi Myat Noe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=KawaguchiAyano en-aut-sei=Kawaguchi en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=189 end-page=197 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=Relationship between Maternal Body Composition during Pregnancy and Newborn Birth Weight in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: This study aimed to investigate the changes in maternal body composition during pregnancy in Japanese women and the relationship between maternal body composition and newborn birth weight using pre-pregnancy body mass index (BMI) in all trimesters.
Methods: A total of 1,851 pregnant Japanese women were enrolled in this study. Body composition was measured using TANITA MC-190EM. The associations between newborn birth weight and maternal BMI, fat mass (FM), fat-free mass (FFM), total body water (TBW), muscle mass (MM), FM gain, FFM gain, and weight gain were evaluated.
Results: The participants’ age and pre-pregnancy BMI were 34.1 years and 21.4 kg/m2, respectively. Among the patients, 13.4%, 73.0%, 10.3%, and 3.3% were underweight, average weight, overweight, and obese, respectively. The FM showed no significant change from the second to third trimesters in the underweight, overweight, and obese groups. Moreover, the FM in the overweight and obese groups did not change during any period. The FFM, TBW, and MM significantly increased from the first to second and second to third trimesters. In BMI-stratified multivariate regression analyses, FFM in the normal and overweight groups was positively associated with birth weight, whereas FM gain was negatively associated in the underweight and normal groups. No significant associations were observed in the obese group.
Conclusions: Changes in maternal body composition during pregnancy in Japanese women varied by pre-pregnancy BMI. Associations with birth weight also differed by BMI group. Further prospective studies are needed to confirm these relationships and investigate the mechanisms. en-copyright= kn-copyright= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoMasakazu en-aut-sei=Kato en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KirinoSatoe en-aut-sei=Kirino en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuriyamaChiaki en-aut-sei=Kuriyama en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakataShujiro en-aut-sei=Sakata en-aut-mei=Shujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakatoHikari en-aut-sei=Nakato en-aut-mei=Hikari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MishimaSakurako en-aut-sei=Mishima en-aut-mei=Sakurako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhiraAkiko en-aut-sei=Ohira en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=maternal body composition kn-keyword=maternal body composition en-keyword=newborn birth weight kn-keyword=newborn birth weight en-keyword=pre-pregnancy body mass index kn-keyword=pre-pregnancy body mass index en-keyword=fat-free mass kn-keyword=fat-free mass en-keyword=fat mass gain kn-keyword=fat mass gain END
