SARM1 plays a pivotal role in triggering the neurodegenerative processes that underlie peripheral neuropathies, traumatic brain injury, and neurodegenerative diseases. Importantly, SARM1 knockdown or knockout prevents the degeneration; as a result, SARM1 has been attracting attention as a potent therapeutic target. In recent years, the development of several SARM1 inhibitors derived from synthetic chemical compounds has been reported; however, no dietary ingredients with SARM1 inhibitory activity have been identified. Therefore, we here focused on dietary ingredients and found that carnosol, an antioxidant contained in rosemary, inhibits the NAD+-cleavage activity of SARM1. Purified carnosol inhibited the enzymatic activity of SARM1 and suppressed neurite degeneration and cell death induced by the anti-cancer medicine vincristine (VCR). Carnosol also inhibited VCR-induced hyperalgesia symptoms, suppressed the loss of intra-epidermal nerve fibers in vivo, and reduced the blood fluid level of phosphorylated neurofilament-H caused by an axonal degeneration event. These results indicate that carnosol has a neuroprotective effect via SARM1 inhibition in addition to its previously known antioxidant effect via NF-E2-related factor 2 and thus suppresses neurotoxin-induced peripheral neuropathy. en-copyright= kn-copyright= en-aut-name=MurataHitoshi en-aut-sei=Murata en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaKazuki en-aut-sei=Ogawa en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiYu en-aut-sei=Yasui en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OchiToshiki en-aut-sei=Ochi en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomonobuNahoko en-aut-sei=Tomonobu en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoKen-Ichi en-aut-sei=Yamamoto en-aut-mei=Ken-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinoshitaRie en-aut-sei=Kinoshita en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WadaYoji en-aut-sei=Wada en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakamuraHiromichi en-aut-sei=Nakamura en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Tama Biochemical Co., Ltd. kn-affil= affil-num=3 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Tama Biochemical Co., Ltd. kn-affil= affil-num=9 en-affil=Tama Biochemical Co., Ltd. kn-affil= affil-num=10 en-affil=Department of Translational Research and Drug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=SARM1 kn-keyword=SARM1 en-keyword=carnosol kn-keyword=carnosol en-keyword=NAD+ kn-keyword=NAD+ en-keyword=axon degeneration kn-keyword=axon degeneration en-keyword=peripheral neuropathy kn-keyword=peripheral neuropathy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202510319 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250626 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a Vinylated Cyclic Allene: A Fleeting Strained Diene for the Diels–Alder Reaction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fleeting molecules possessing strained multiple bonds are important components in organic synthesis due to their ability to undergo various chemical reactions driven by the release of strain energy. Although the use of strained π-bonds as 2π components, represented by dienophiles in Diels–Alder reactions, has been well studied, “the strained diene (4π component) approach” for molecular construction remains underexplored. Herein, we report the design of a vinyl cyclic allene (1-vinyl-1,2-cyclohexadiene) as a highly reactive strained diene and the development of its Diels–Alder reactions. Experimental and computational studies of vinyl cyclic allenes revealed that this diene system undergoes cycloaddition with dienophiles regio- and stereoselectively under mild reaction conditions. These studies also provide insight into the reactivity and selectivity of the system. The strained diene approach enables the convergent construction of polycyclic molecules through bond disconnections distinct from conventional retrosynthetic analysis, thus offering an efficient strategy for the assembly of functional molecules. en-copyright= kn-copyright= en-aut-name=MizoguchiHaruki en-aut-sei=Mizoguchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataTakumi en-aut-sei=Obata en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraiTaiki en-aut-sei=Hirai en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KomatsuManaka en-aut-sei=Komatsu en-aut-mei=Manaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakakuraAkira en-aut-sei=Sakakura en-aut-mei=Akira 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=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Activation strain model kn-keyword=Activation strain model en-keyword=Carbocycles kn-keyword=Carbocycles en-keyword=Diels–Alder reaction kn-keyword=Diels–Alder reaction en-keyword=Strained diene kn-keyword=Strained diene en-keyword=Vinylated cyclic allene kn-keyword=Vinylated cyclic allene END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=3 article-no= start-page=152 end-page=161 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Osteogenesis imperfecta: pathogenesis, classification, and treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osteogenesis imperfecta (OI) is a congenital skeletal disorder characterized by varying degrees of bone fragility and deformities. Extraskeletal manifestations, such as blue sclera, dentinogenesis imperfecta, growth disturbance, hearing impairment, and muscle weakness, occasionally accompany OI. Many genes have been identified as causative of OI, such as the type I collagen gene and genes involved in the folding, processing, and crosslinking of type I collagen molecules, osteoblast differentiation, and bone mineralization. According to the discovery of the causative gene of OI, nosology and classifications have also been revised and the “dyadic approach” based nomenclature according to the severity and each causative gene of OI was recently adopted. Intravenous or oral bisphosphonates have been administered to treat bone fragility in children with OI and a reduction in the frequency of bone fractures has been reported. However, despite the increase of bone mineral density, evidence of bone fracture prevention is limited. Recently, excessive transforming growth factor β signaling pathway and excessive endoplasmic reticulum stress have been reported as the pathogenesis of OI, and treatment strategies based on these pathogeneses have been developed. This review summarizes the molecular basis, transition of nosology and classification, status of bisphosphonate therapy, and development of treatment strategies. en-copyright= kn-copyright= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= en-keyword=fracture kn-keyword=fracture en-keyword=child kn-keyword=child en-keyword=bisphosphonate kn-keyword=bisphosphonate en-keyword=classification kn-keyword=classification en-keyword=treatment kn-keyword=treatment END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7 article-no= start-page=930 end-page=938 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hemodynamic Changes After Wire Frame Occluders vs. Metal Mesh Devices for Atrial Septal Defect en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Transcatheter atrial septal defect (ASD) closure is the first treatment option for secundum ASD, but parameters for optimal device selection have not been established. We compared outcomes between occluders with a wire frame and metal mesh devices.
Methods and Results: This study included secundum ASD patients implanted with a wire frame occluder (GORE®CARDIOFORM ASD occluder [GCA]; W.L. Gore & Associates) or metal mesh devices (Amplatzer septal occluder device [Abbott] and Occlutech Figulla Flex II device [Occlutech]). The presence of residual shunt and B-type natriuretic peptide (BNP) levels after implantation were compared. Of the 970 patients with either GCA (n=48) or a metal mesh device (n=922; control), 42 patients from each group were analyzed after propensity score matching. The prevalence of residual shunt was significantly lower in the GCA group 1 day and 1 month after implantation (P<0.001 and P=0.017, respectively), whereas there was no significant difference between the 2 groups 6 months later (P=0.088). BNP levels at 1 month were significantly higher in the GCA group (ratio of change 1.36; 95% confidence interval [CI] 1.01–1.83), but did not differ significantly between the 2 groups at 6 months (ratio of change 1.04; 95% CI 0.65–1.65).
Conclusions: Patients implanted with a wire frame occluder had a lower prevalence of residual shunt and a greater increase in BNP levels in the early period after implantation. en-copyright= kn-copyright= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EjiriKentaro en-aut-sei=Ejiri en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiTakashi en-aut-sei=Miki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkagiTeiji en-aut-sei=Akagi en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, 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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Amplatzer septal occluder kn-keyword=Amplatzer septal occluder en-keyword=GORE® CARDIOFORM ASD occluder kn-keyword=GORE® CARDIOFORM ASD occluder en-keyword=Occlutech Figulla Flex II kn-keyword=Occlutech Figulla Flex II en-keyword=Transcatheter atrial septal defect closure kn-keyword=Transcatheter atrial septal defect closure END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of transcatheter patent foramen ovale closure for drug-resistant migraine: initial experience in Japan and long-term outcome en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study evaluates the efficacy and safety of transcatheter patent foramen ovale (PFO) closure for the treatment of drug-resistant migraine in Japan. Previous studies have suggested a potential benefit for migraine with aura, although large-scale trials in the United States and Europe have failed to confirm efficacy as a primary endpoint. The study included 27 patients (mean age 36.4 years, 15 female, 21 with aura) who had more than two migraine attacks per month despite medication. All had PFO confirmed by transesophageal echocardiography and underwent transcatheter closure with the Amplatzer PFO Occluder. Patients were followed up to 12 months with migraine severity monitored by headache specialist. The procedure was successful and without complications in all cases. One patient required a larger occluder (35 mm) due to the size of PFO. At 12 months, 22 of 27 (81%) patients reported either complete resolution or improvement of migraine. Specifically, 10 of 21 (48%) patients with aura experienced complete resolution of migraine at one year. Patients without aura had a lower response rate, with only one case of complete resolution. Despite limitations such as the lack of a control group and potential patient selection bias, the study demonstrated that PFO closure may provide significant relief for patients with drug-resistant migraine, particularly those with aura. These findings support further investigation to better define its clinical indications and potential benefits. en-copyright= kn-copyright= en-aut-name=AkagiTeiji en-aut-sei=Akagi en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MikiTakashi en-aut-sei=Miki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakashimaMitsuki en-aut-sei=Nakashima en-aut-mei=Mitsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiYoshiaki en-aut-sei=Takahashi en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HishikawaNozomi en-aut-sei=Hishikawa en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Patent foramen ovale kn-keyword=Patent foramen ovale en-keyword=Migraine kn-keyword=Migraine en-keyword=Headache kn-keyword=Headache en-keyword=Stroke kn-keyword=Stroke en-keyword=Catheter kn-keyword=Catheter END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=e70055 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Short‐process incudo‐stapedioplasty in congenital ear malformation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Although various stapedotomy and stapedectomy techniques exist, anchoring the piston can be challenging. We present a novel surgical approach for treating congenital stapes malformations with an atypical facial nerve trajectory.
Methods: This is a case of a 7-year-old boy presenting with bilateral conductive hearing loss. Prior attempts at tympanoplasty had proven unsuccessful in improving his hearing. Presurgical imaging studies revealed an unusual anatomical configuration, with the facial nerve positioned inferior to the oval window. This anatomical variation precluded the use of conventional prosthesis-anchoring techniques typically employed in stapedotomies. Thus, we devised an innovative approach, opting to anchor the prosthesis to the short process of the incus.
Results: This novel technique circumvented the atypical course of the facial nerve, allowing for successful reconstruction of the ossicular chain. The patient demonstrated an acceptable improvement (30 dB gain) in hearing 1-year post-surgery, with no reported complications.
Conclusion: This case underscores the critical importance of adapting surgical techniques to address the unique anatomical challenges that may arise in the context of congenital ear malformations. It also highlights the potential of the short process of the incus as a viable alternative anchoring site for stapes prostheses, thereby improving the outcomes of such complex cases. This technique not only restored the patient's hearing but also contributed valuable insights into the management of similar cases, potentially improving the quality of life for individuals with rare and challenging anatomical variations.

To evaluate this serious complication, we used “Quick Dash” or “FACT-B”, which can assess a patient's physical, social, emotional, and functional health status. To evaluate their breast cancer surgery-related dysfunction correctly, “FACT-B + 4” was created by adding four questions about “arm swelling'' and “tenderness”. We have translated it into Japanese according to international translation guidelines.
Methods At the beginning, we contacted FACT headquarters that we would like to create a Japanese version of FACT-B + 4. They formed the FACIT Trans Team (FACIT) following international translation procedures, and then, we began translating according to them. The steps are 1: perform “Forward and Reverse translations” to create a “Preliminary Japanese version”, 2: request the cooperation of 5 breast cancer patients and “conduct a pilot study” and “questionnaire survey”, and 3: amendments and final approval based on pilot study results and clinical perspectives.
Result In Step1, FACIT requested faithful translation of the words, verbs, and nouns from the original text. In Step2, patients reported that they felt uncomfortable with the Japanese version words such as “numb'' and “stiffness'' and felt that it might be difficult to describe their symptoms accurately. In Step3, we readjusted the translation to be more concise and closer to common Japanese language, and performed “Step1” again to ensure that the translation definitely retained the meaning of the original.
Conclusion A Japanese version of FACT has existed until now, but there was no Japanese version of FACT-B + 4, which adds four additional items to evaluate swelling and pain in the upper limbs. This time, we have created a Japanese version that has been approved by FACT. en-copyright= kn-copyright= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakataNozomu en-aut-sei=Takata en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DennisSaya R. en-aut-sei=Dennis en-aut-mei=Saya R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TerataKaori en-aut-sei=Terata en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SagaraYasuaki en-aut-sei=Sagara en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaiTakehiko en-aut-sei=Sakai en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakayamaShin en-aut-sei=Takayama en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KitagawaDai en-aut-sei=Kitagawa en-aut-mei=Dai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KikawaYuichiro en-aut-sei=Kikawa en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IwataniTsuguo en-aut-sei=Iwatani en-aut-mei=Tsuguo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaraFumikata en-aut-sei=Hara en-aut-mei=Fumikata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujisawaTomomi en-aut-sei=Fujisawa en-aut-mei=Tomomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Simpson Querrey Biomedical Research Center, Northwestern University kn-affil= affil-num=3 en-affil=Department of Preventive Medicine Feinberg School of Medicine, Northwestern University kn-affil= affil-num=4 en-affil=Department of Breast and Endocrine Surgery, Akita University Hospital kn-affil= affil-num=5 en-affil=Department of Breast Surgical Oncology, Social Medical Corporation Hakuaikai Sagara Hospital kn-affil= affil-num=6 en-affil=Department of Surgical Oncology, Breast Oncology Center, Cancer Institute Hospital of JFCR kn-affil= affil-num=7 en-affil=Department of Breast Surgery, National Cancer Center Hospital kn-affil= affil-num=8 en-affil=Department of Breast Surgical Oncology, National Center for Global Health and Medicine kn-affil= affil-num=9 en-affil=Department of Breast Surgery, Kansai Medical University Hospital kn-affil= affil-num=10 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Breast Oncology, Aichi Cancer Center Hospital kn-affil= affil-num=13 en-affil=Department of Breast Cancer, Gunma Prefectural Cancer Center kn-affil= affil-num=14 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=FACT-B kn-keyword=FACT-B en-keyword=FACT-B+4 kn-keyword=FACT-B+4 en-keyword=QOL kn-keyword=QOL END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=321 end-page=343 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Physiological and Biochemical Traits of Dormancy Release and Growth Resumption in Japanese Cedar in the Warm-Temperate Zone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Global warming will disturb dormancy release and growth resumption of trees. To better understand this process, it is important to investigate physiological and biochemical traits related to these stages. We examined dormancy release and growth resumption in Japanese cedar (Cryptomeria japonica [L.] D. Don), an evergreen needle-leaved tree, in the warm-temperate zone by evaluating budbreak under growth-promoting conditions, and simultaneously examining respiration rates and contents of carbohydrates and phytohormones in shoots from November 2022 to March 2023. A long time to budbreak and the lowest budbreak rates of 75% in November indicated shallow dormancy. Budbreak rates of 98%, short time to budbreak, and first appearance of budbreak in the field in March indicated growth resumption. Continuous changes in budbreak rates and time to budbreak between dormancy and growth resumption indicated dormancy was gradually released. Surges in budbreak rates in December indicated dormancy was almost completely released by early winter. Contents of abscisic acid (ABA) and salicylic acid (SA) decreased from November, remained low in March, and were strongly associated with budbreak rates according to principal component analysis. It was suggested that the depletion of SA led to the depletion of ABA, contributing to dormancy release and growth resumption. Fructose and trans-zeatin accumulated until February, and low levels of starch, indole-3-acetic acid, jasmonic acid, and jasmonic acid-isoleucine during winter was followed by accumulation in March. Although these biochemical traits were less related to budbreak rates compared to ABA and SA, they seemed to assist either dormancy release or growth resumption. en-copyright= kn-copyright= en-aut-name=HiejimaShoma en-aut-sei=Hiejima en-aut-mei=Shoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SeinoHiroto en-aut-sei=Seino en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HachisukaRico en-aut-sei=Hachisuka en-aut-mei=Rico kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeYuka en-aut-sei=Watanabe en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= 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=6 ORCID= en-aut-name=UgawaShin en-aut-sei=Ugawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Forestry and Fisheries, Kagoshima University kn-affil= affil-num=3 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Forestry and Fisheries, Kagoshima 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=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= en-keyword=Japanese cedar kn-keyword=Japanese cedar en-keyword=Warm-temperate zone kn-keyword=Warm-temperate zone en-keyword=Dormancy release kn-keyword=Dormancy release en-keyword=Growth resumption kn-keyword=Growth resumption en-keyword=Physio-biochemical traits kn-keyword=Physio-biochemical traits END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=5434-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Secondary aortoduodenal fistula in a patient with vascular Behçet's disease en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Aortoduodenal fistula kn-keyword=Aortoduodenal fistula en-keyword=repeated bacteremia kn-keyword=repeated bacteremia en-keyword=polymicrobial bacteremia kn-keyword=polymicrobial bacteremia en-keyword=graft infection kn-keyword=graft infection END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=1692 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Characteristics of Vitamin D Deficiency Detected in Long COVID Patients During the Omicron Phase en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: To characterize the clinical significance of vitamin D deficiency (VDD) detected in long COVID, a retrospective observational study was performed for outpatients who visited our clinic during the period from May 2024 to November 2024. Methods: Clinical trends in long COVID patients diagnosed with VDD who showed serum concentrations of 25-hydroxyvitamin D (25-OHD) lower than 20 ng/mL were compared with those in long COVID patients in a non-deficient vitamin D (NDD) group. Results: Of 126 patients with long COVID, 97 patients (female: 50) who had been infected during the Omicron phase were included. Sixty-six patients (68%) were classified in the VDD group. The median serum concentrations of 25-OHD were 14.8 ng/mL in the VDD group and 22.9 ng/mL in the NDD group. There were no significant differences between the two groups in terms of age, gender, BMI, severity of COVID-19, period after infection and vaccination history. Although the levels of serum calcium and phosphate were not significantly different between the two groups, the percentages of patients in the VDD group who complained of dizziness, memory impairment, palpitation and appetite loss were larger than those in the NDD group. Of note, the patients who complained of palpitation showed significantly lower concentrations of serum 25-OHD than those in the patients without palpitation (median: 11.9 vs. 17.3 ng/mL). Moreover, patients in the VDD group had significantly higher scores for physical and mental fatigue as well as higher scores for depressive symptoms. Conclusions: Collectively, VDD is involved in clinical manifestations of long COVID, particularly symptoms of palpitation, fatigue and depression. en-copyright= kn-copyright= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui 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=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro 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=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YokotaYuya en-aut-sei=Yokota en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 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 General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=25-hydroxyvitamin D kn-keyword=25-hydroxyvitamin D en-keyword=long COVID kn-keyword=long COVID en-keyword=palpitation kn-keyword=palpitation en-keyword=vitamin D deficiency kn-keyword=vitamin D deficiency END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=e000923 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reversible cerebral vasoconstriction syndrome in idiopathic multicentric Castleman disease under treatment with tocilizumab en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Idiopathic multicentric Castleman disease (iMCD) is a rare polyclonal lymphoproliferative disorder characterised by systemic inflammation resulting from overproduction of interleukin 6 (IL-6). While iMCD primarily affects the lymph nodes and related tissues, it can also rarely involve the central nervous system.
Case presentation We report the case of a 58-year-old female patient with at least a 3-year history of iMCD, who experienced acute thunderclap headaches due to reversible cerebral vasoconstriction syndrome (RCVS). RCVS occurred 3 months after initiating treatment with tocilizumab, a humanised anti-IL-6 receptor monoclonal antibody, and was accompanied by focal cortical subarachnoid haemorrhage (SAH). Elevated IL-6 levels were found in both serum and cerebrospinal fluid. MR angiography revealed multiple diffuse stenotic lesions in the bilateral middle and posterior cerebral arteries, which, along with bilateral cerebral oedema, resolved within 3 months. The diffuse nature of the cerebral vasospasm and the presence of bilateral brain oedema suggested that cerebral vasospasm was due to RCVS rather than SAH.
Conclusions In patients with Castleman disease, RCVS may occur due to IL-6-dependent chronic cerebral vascular inflammation, either as a primary condition or as a complication of tocilizumab treatment. en-copyright= kn-copyright= en-aut-name=KamimuraNaoya en-aut-sei=Kamimura en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UedaNaohisa en-aut-sei=Ueda en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraKatsuo en-aut-sei=Kimura en-aut-mei=Katsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishidaHitaru en-aut-sei=Kishida en-aut-mei=Hitaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaFumiaki en-aut-sei=Tanaka en-aut-mei=Fumiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=2 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=3 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=7 en-affil=Department of Neurology and Stroke Medicine, Yokohama City University Graduate School of Medicine kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=4 article-no= start-page=510 end-page=524 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250626 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C1orf50 Drives Malignant Melanoma Progression Through the Regulation of Stemness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Recent advancements in omics analysis have significantly enhanced our understanding of the molecular pathology of malignant melanoma, leading to the development of novel therapeutic strategies that target specific vulnerabilities within the disease. Despite these improvements, the factors contributing to the poor prognosis of patients with malignant melanoma remain incompletely understood. The aim of this study was to investigate the role of C1orf50 (Chromosome 1 open reading frame 50), a gene previously of unknown function, as a prognostic biomarker in melanoma.
Materials and Methods: We performed comprehensive transcriptome data analysis and subsequent functional validation of the human Skin Cutaneous Melanoma project from The Cancer Genome Atlas (TCGA).
Results: Elevated expression levels of C1orf50 correlated with worse survival outcomes. Mechanistically, we revealed that C1orf50 plays a significant role in the regulation of cell cycle processes and cancer cell stemness, providing a potential avenue for novel therapeutic interventions in melanoma.
Conclusion: This study is the first to identify C1orf50 as a prognostic biomarker in melanoma. The clinical relevance of our results sheds light on the importance of further investigation into the biological mechanisms underpinning C1orf50’s impact on melanoma progression and patient prognosis. en-copyright= kn-copyright= en-aut-name=OTANIYUSUKE en-aut-sei=OTANI en-aut-mei=YUSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MAEKAWAMASAKI en-aut-sei=MAEKAWA en-aut-mei=MASAKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TANAKAATSUSHI en-aut-sei=TANAKA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PEÑATIRSO en-aut-sei=PEÑA en-aut-mei=TIRSO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CHINVANESSA D. en-aut-sei=CHIN en-aut-mei=VANESSA D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ROGACHEVSKAYAANNA en-aut-sei=ROGACHEVSKAYA en-aut-mei=ANNA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TOYOOKASHINICHI en-aut-sei=TOYOOKA en-aut-mei=SHINICHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ROEHRLMICHAEL H. en-aut-sei=ROEHRL en-aut-mei=MICHAEL H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FUJIMURAATSUSHI en-aut-sei=FUJIMURA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=2 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=3 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=4 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=5 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=6 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=9 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=melanoma kn-keyword=melanoma en-keyword=cancer stem cells kn-keyword=cancer stem cells en-keyword=YAP/TAZ kn-keyword=YAP/TAZ END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Towards SBOM-based Access Control for Transparent and Explicit Program Execution en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although a Software Bill of Materials (SBOM) plays a key role in software transparency, inconsistencies in SBOM descriptions can undermine its value.

Factors such as tool geometry, machining path, work material characteristics, machining efficiency, and finishing accuracy must be taken into consideration. However, the current method of determining cutting conditions relies heavily on the intuition and experience of skilled engineers, and there is a need for a system to replace such knowledge. One of the critical factors affecting machining accuracy and efficiency is the tool overhang length, which is directly related to tool geometry. Unfortunately, there is no clear guideline for its determination. In a previous study, researchers developed a system to quickly derive cutting conditions using a data mining method and Random Forest Regression (RFR) applied to a tool catalog database. In this study, we constructed a new cutting condition compensation system based on the existing model, which accounts for the tool overhang length. The results of cutting experiments under high aspect ratio overhang lengths confirm that the correction coefficients proposed by the system are significant. en-copyright= kn-copyright= en-aut-name=KODAMAHiroyuki en-aut-sei=KODAMA en-aut-mei=Hiroyuki kn-aut-name=児玉紘幸 kn-aut-sei=児玉 kn-aut-mei=紘幸 aut-affil-num=1 ORCID= en-aut-name=MORIYAYuki en-aut-sei=MORIYA en-aut-mei=Yuki kn-aut-name=守屋祐輝 kn-aut-sei=守屋 kn-aut-mei=祐輝 aut-affil-num=2 ORCID= en-aut-name=MORIMOTOTatsuo en-aut-sei=MORIMOTO en-aut-mei=Tatsuo kn-aut-name=盛元達雄 kn-aut-sei=盛元 kn-aut-mei=達雄 aut-affil-num=3 ORCID= en-aut-name=OHASHIKazuhito en-aut-sei=OHASHI en-aut-mei=Kazuhito kn-aut-name=大橋一仁 kn-aut-sei=大橋 kn-aut-mei=一仁 aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 学術研究院環境生命自然科学学域 affil-num=2 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 大学院環境生命自然科学研究科 affil-num=3 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 大学院環境生命自然科学研究科 affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 学術研究院環境生命自然科学学域 en-keyword=Data mining kn-keyword=Data mining en-keyword=Cutting conditions kn-keyword=Cutting conditions en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Random Forest Regression kn-keyword=Random Forest Regression en-keyword=Ball end-mill kn-keyword=Ball end-mill en-keyword=Tool overhang length kn-keyword=Tool overhang length END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dual functions of SNAP25 in mouse taste buds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Type III cells in mouse taste buds are considered to transmit aversive stimuli, such as sourness, to the gustatory nerve through vesicular synapses. Synaptosome-associated protein 25 (SNAP25) might contribute to synaptic vesicular release in sour sensation, although direct evidence has been lacking. Here, we demonstrated that epithelia-specific Snap25 conditional knockout (cKO) mice exhibited a significant reduction in the number of type III cells. Notably, the proportion of 5-ethynyl 2′-deoxyuridine-positive post-mitotic type III cells in Snap25 cKO mice was significantly lower on tracing day 14, but not at day 7, which suggests that SNAP25 contributes to the maintenance of type III cells. In a short-term lick test, Snap25 cKO (sour taste absent) and Snap25/ transient receptor potential vanilloid 1 double KO (sour taste and somatosensory absent) mice exhibit a significantly higher lick response to sour tastants, confirming the role of SNAP25 for sour sensation. Electrophysiological recordings of the chorda tympani nerve reveal nearly abolished ammonium and sour taste responses in Snap25 cKO mice, which concludes sour-dependent synapse transmission in type III cells. Overall, these data suggest that vesicular synapses in taste buds are indispensable for transmission of information from, and the replenishment of, sour-sensitive type III taste cells. en-copyright= kn-copyright= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangKuanyu en-aut-sei=Wang en-aut-mei=Kuanyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HuangHai en-aut-sei=Huang en-aut-mei=Hai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasumatsuKeiko en-aut-sei=Yasumatsu en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NinomiyaYuzo en-aut-sei=Ninomiya en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=Tokyo Dental Junior College kn-affil= affil-num=5 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=sour taste kn-keyword=sour taste en-keyword=synapse kn-keyword=synapse en-keyword=taste buds kn-keyword=taste buds en-keyword=taste nerve kn-keyword=taste nerve en-keyword=Type III cells kn-keyword=Type III cells END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=3 article-no= start-page=337 end-page=345 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Study on the Grinding Temperature of Workpiece in Side Plunge Grinding Process en-subtitle= kn-subtitle= en-abstract= kn-abstract=Grinding is used to finish thrust metal attachment parts, such as crankshafts, which have both journal and thrust surfaces. In side plunge grinding, a thrust surface and a cylindrical surface of a shaft workpiece with collars are finished in a single plunge grinding process. However, the surface quality near the ground internal corner, where grinding fluid may not penetrate, can deteriorate, causing high residual stress and cracks owing to grinding heat. While it has been reported that quality issues at the inner corners of the ground surface can be mitigated by reducing the grinding point temperature through efficient cooling fluid supply, the mechanisms of grinding phenomena and heat generation in side plunge grinding are not yet fully understood. In this study, the variations in the grinding temperature at the thrust surface of a workpiece with a collar were experimentally investigated using a wire/workpiece thermocouple to clarify these phenomena. The results revealed a significant increase in the grinding temperature at the corners of the grinding zone. However, it slightly decreases as the thermocouple output approaches the center of the workpiece, indicating a slight effect of the grinding speed. The surface temperature of the workpiece in side plunge grinding is primarily influenced by the wheel depth-of-cut in the thrust direction. Additionally, the effect of workpiece rotational speed and grinding infeed speed on temperature distribution has been demonstrated. en-copyright= kn-copyright= en-aut-name=GaoLingxiao en-aut-sei=Gao en-aut-mei=Lingxiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuidaMotoki en-aut-sei=Kuida en-aut-mei=Motoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KodamaHiroyuki en-aut-sei=Kodama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhashiKazuhito en-aut-sei=Ohashi en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=grinding kn-keyword=grinding en-keyword=thrust surface kn-keyword=thrust surface en-keyword=grinding temperature kn-keyword=grinding temperature en-keyword=thermocouple kn-keyword=thermocouple END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=85 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CyNER: Information Extraction from Unstructured Text of CTI Sources with Noncontextual IOCs en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cybersecurity threats have been increasing and growing more sophisticated year by year. In such circumstances, gathering Cyber Threat Intelligence (CTI) and following up with up-to-date threat information is crucial. Structured CTI such as Structured Threat Information eXpression (STIX) is particularly useful because it can automate security operations such as updating FW/IDS rules and analyzing attack trends. However, as most CTIs are written in natural language, manual analysis with domain knowledge is required, which becomes quite time-consuming.
In this work, we propose CyNER, a method for automatically structuring CTIs and converting them into STIX format. CyNER extracts named entities in the context of CTI and then extracts the relations between named entities and IOCs in order to convert them into STIX. In addition, by using key phrase extraction, CyNER can extract relations between IOCs that lack contextual information, such as those listed at the bottom of a CTI, and named entities. We describe our design and implementation of CyNER and demonstrate that it can extract named entities with the F-measure of 0.80 and extract relations between named entities and IOCs with the maximum accuracy of 81.6%. Our analysis of structured CTI showed that CyNER can extract IOCs that are not included in existing reputation sites, and that it can automatically extract IOCs that have been exploited for a long time and across multiple attack groups. CyNER is thus expected to contribute to the efficiency of CTI analysis. en-copyright= kn-copyright= en-aut-name=FujiiShota en-aut-sei=Fujii en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaguchiNobutaka en-aut-sei=Kawaguchi en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigemotoTomohiro en-aut-sei=Shigemoto en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research & Development Group, Hitachi, Ltd. kn-affil= affil-num=3 en-affil=Research & Development Group, Hitachi, Ltd. kn-affil= affil-num=4 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=292 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analyzing Post-injection Attacker Activities in IoT Devices: A Comprehensive Log Analysis Approach en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the continuous proliferation of Internet of Things (IoT) devices, malware threats that specifically target these devices continue to increase. The urgent need for robust security measures is predicated on a comprehensive understanding of the behavioral patterns of IoT malware. However, previous studies have often overlooked the analysis of command sequences in Telnet logs. This study bridges this research gap by examining the post-injection behaviors of attackers. By analyzing a vast dataset comprising more than ten million logs collected from an IoT honeypot, we reveal three distinct post-injection activity patterns, each with unique characteristics. These patterns provide pivotal insights that not only help distinguish between legitimate operations and attempted attacks, but also drive the development of robust cybersecurity measures that effectively deter such behaviors. The nuances discovered in this study contribute significantly to IoT security by enhancing our understanding of malware tactics and informing targeted defense strategies. en-copyright= kn-copyright= en-aut-name=VictorHervet en-aut-sei=Victor en-aut-mei=Hervet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Malware analysis kn-keyword=Malware analysis en-keyword=IoT kn-keyword=IoT en-keyword=Honeypot kn-keyword=Honeypot en-keyword=Log analysis kn-keyword=Log analysis en-keyword=Attack patterns kn-keyword=Attack patterns END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=274 end-page=278 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevention Method for Stack Buffer Overflow Attack in TA Command Calls in OP-TEE en-subtitle= kn-subtitle= en-abstract= kn-abstract=TEE systems provide normal world and secure world.

We also propose a method for preventing attacks that exploit stack buffer overflows in TA command calls. In addition, the experimental results show that attacks on the vulnerable TAs can be prevented with the proposed method and the overhead can be evaluated. en-copyright= kn-copyright= en-aut-name=ShibaKaito en-aut-sei=Shiba en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuzunoHiroki en-aut-sei=Kuzuno en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Engineering, Kobe University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Trusted execution environment kn-keyword=Trusted execution environment en-keyword=Stack overflow prevention method kn-keyword=Stack overflow prevention method en-keyword=System security kn-keyword=System security END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=161 end-page=167 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Effectiveness of MAC Systems Based on LSM for Protecting IoT Devices en-subtitle= kn-subtitle= en-abstract= kn-abstract=Numerous active attacks targeting Internet of Things (IoT) devices exist. They exploit the latest vulnerabilities discovered in IoT devices. Therefore, Mandatory Access Control (MAC) systems based on Linux Security Modules (LSM), such as SELinux and AppArmor, are effective security features for IoT devices because they can mitigate the impact of attacks even if software vulnerabilities are discovered. However, they are not adopted by most IoT devices. The existing approaches are insufficient for investigating the causes of this problem.In this study, we comprehensively investigated what factors can affect the applicability of MAC systems based on LSM in IoT devices. We focused on how frequently cases can occur where they cannot be adopted, owing to each factor. To increase the comprehensiveness of the factors affecting the adoption of MAC systems in IoT devices, we investigated the kernel version, CPU architecture, and support for BusyBox in addition to the investigation of resources, which conducted in previous studies. We also conducted simulated experiments based on the attack method of Mirai to investigate whether MAC systems can protect against IoT malware. Finally, we discuss the impact of a combination of these factors on MAC system adoption. en-copyright= kn-copyright= en-aut-name=MikiMasato en-aut-sei=Miki en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Mandatory Access Control System kn-keyword=Mandatory Access Control System en-keyword=IoT Security kn-keyword=IoT Security en-keyword=Linux Security Modules kn-keyword=Linux Security Modules END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=236 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Non Real-Time Data Transmission Performance Analysis of PROFINET for Assuring Data Transmission Quality en-subtitle= kn-subtitle= en-abstract= kn-abstract=The industrial Ethernet PROFINET supports three different data transmission modes: isochronous real-time (IRT), real-time (RT), and non real-time (NRT) transmitting data requiring hard, soft, and no real-time performances, respectively. The data transmission latency in the NRT increased with the amount of data transmission in the IRT, RT, and NRT. Therefore, the quality of data transmission in NRT may degrade as the amount of data transmission in IRT, RT, and NRT increases. In this study, we derived the average data transmission latency in an NRT with data transmission in IRT and RT by applying stochastic processes. This allowed us to maintain the quality of data transmission in the NRT by adjusting the number of devices connected to the network and the number of applications transmitting data in the NRT so that the average latency of data in the NRT does not exceed a certain value. en-copyright= kn-copyright= en-aut-name=NorimatsuTakashi en-aut-sei=Norimatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Industrial Ethernet kn-keyword=Industrial Ethernet en-keyword=PROFINET kn-keyword=PROFINET en-keyword=Non Real Time kn-keyword=Non Real Time en-keyword=Real-Time kn-keyword=Real-Time en-keyword=Isochronous Real Time kn-keyword=Isochronous Real Time END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=267 end-page=273 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supporting Multiple OS Types on Estimation of System Call Hook Point by Virtual Machine Monitor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methods to hook system calls issued by a guest operating system (OS) running on a virtual machine using a virtual machine monitor are proposed. The address of the hook point is derived from the guest OS’s source code and established prior to the kernel startup process. Due to changes in system call processing in OS updates and address space layout randomization, the addresses of these hook points cannot always be pre-determined before the kernel startup process. To address this challenge, a method for estimating the system call hook point is proposed in Linux by analyzing the guest OS memory on x86-64 CPUs rather than pre-calculation. Although the method supports Linux, the method can be extended to support other OS types. In this paper, we propose a method to extend the method to support additional OSes. Specifically, we present analysis results and a novel method for estimating hook points on FreeBSD, NetBSD, and OpenBSD. The effectiveness of our proposed method is also demonstrated through evaluation. en-copyright= kn-copyright= en-aut-name=SatoMasaya en-aut-sei=Sato en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmoriTaku en-aut-sei=Omori en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniguchiHideo en-aut-sei=Taniguchi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama Prefectural University kn-affil= affil-num=2 en-affil=Okayama Prefectural University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= en-keyword=system call kn-keyword=system call en-keyword=virtual machine monitor kn-keyword=virtual machine monitor en-keyword=operating system kn-keyword=operating system END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=107 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation Towards Detecting Landing Websites for Fake Japanese Shopping Websites en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, the number of victims of fake shopping websites that imitate legitimate ones to defraud people has been increasing.

In this study, we collect and investigate existing landing websites that redirect users to fake Japanese shopping websites and identify effective features for detecting them. We identified effective search terms for collecting landing websites for fake Japanese shopping websites and found that using Google searches with queries of top-level domain and product names was effective. We also investigated the conditions for activating analytical evasion functions in the collected landing websites for fake Japanese shopping websites and clarified the differences in search results between crawlers and users. en-copyright= kn-copyright= en-aut-name=MichishitaDaigo en-aut-sei=Michishita en-aut-mei=Daigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e86695 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Managing Persistent Pupillary Membranes With Surgery or Medication: A Report of Three Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=The persistent pupillary membrane, as a congenital anomaly, is a remnant of a network of feeding blood vessels for the lens of the eye, called tunica vasculosa lentis. This study reports three patients with persistent pupillary membrane in both eyes who presented in different situations and were managed differently to achieve better vision. The first child (Case 1) who had been seen initially at the age of two years complained of severe photophobia even though he had good visual acuity, and hence, he and his family chose surgical resection of the pupillary membrane in both eyes at the age of six years just before the admission to an elementary school. He did not develop any surgical complications, such as cataract and glaucoma, and maintained the visual acuity in decimals of 1.2 in both eyes at the age of 17 years.
The second child (Case 2), who was seen first at the age of one month, had persistent pupillary membranes in both eyes, together with Peters' anomaly in the left eye. The iris process adhesion to the corneal inner surface was visualized later by optical coherence tomography. She wore full-correction glasses and obtained the visual acuity of 0.7 in the right eye, so she had no problem studying at an elementary school. She used topical 1% atropine once a week in both eyes to maintain pupillary dilation and also used 0.5% timolol and 1% brinzolamide as pressure-lowering eye drops in the left eye with Peters' anomaly.
The third patient (Case 3) with persistent pupillary membranes in both eyes complained of vision problems for the first time at the age of 49 years when she developed cataract. Surgical resection of the pupillary membrane was done in the initial phase of cataract surgery with intraocular lens implantation in both eyes. At surgical resection of the pupillary membrane, a safe and efficient way was to cut the root of the pupillary membrane on the iris surface with scissors, and then the isolated tissues of the pupillary membrane were pulled out with forceps from the side port at the corneal limbus. Pathological examinations of the excised tissues showed blood vessels with red blood cells in the lumen. In such a rare congenital disease as the persistent pupillary membrane, a case-based approach to choose a better option in different conditions from individual to individual is still required to have a better vision in learning at school and in daily working life. 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= affil-num=1 en-affil=Division of Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=anterior segment dysgenesis kn-keyword=anterior segment dysgenesis en-keyword=cataract kn-keyword=cataract en-keyword=forceps kn-keyword=forceps en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=persistent pupillary membrane kn-keyword=persistent pupillary membrane en-keyword=peters anomaly kn-keyword=peters anomaly en-keyword=resection kn-keyword=resection en-keyword=scissors kn-keyword=scissors en-keyword=vitrectomy cutter kn-keyword=vitrectomy cutter END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e85680 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Whole-Eye Radiation for the Local Control of Choroidal Lymphoma in Primary Central Nervous System Lymphoma: A 14-Year Case Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Involved-site radiation therapy is effective for curative and palliative treatments of cancers, including lymphoma. This case study describes the use of whole-eye radiation for primary intraocular lymphoma occurring during primary central nervous system lymphoma. The patient, a 68-year-old man, developed personality changes and apathy two weeks after cataract surgery combined with vitrectomy for vitreous opacity in the left eye. Magnetic resonance imaging revealed a mass lesion in the left frontal lobe, and biopsy by craniotomy confirmed diffuse large B-cell lymphoma. He underwent chemotherapy using rituximab combined with high-dose methotrexate and high-dose cytarabine in association with intrathecal methotrexate and cytarabine injections, leading to complete remission. At age 75, he noticed forgetfulness, and fluorodeoxyglucose positron emission tomography and magnetic resonance imaging revealed a relapse of lymphoma in the splenium of the corpus callosum. He underwent chemotherapy using rituximab combined with high-dose methotrexate, followed by monthly rituximab monotherapy for one year and then rituximab monotherapy every two months for one year. He maintained complete remission with no treatment until age 78, when he developed subretinal choroidal lesions in the left eye and underwent whole-eye radiation at 40 Gy. One year later, he developed subretinal choroidal lesions in the right eye and underwent whole-eye radiation at 40 Gy. At age 81, he had lower limb weakness with disorientation. Magnetic resonance imaging showed a relapse of lymphoma in the right frontal to temporal lobe. The brain lesions showed a marked response to four weeks of oral tirabrutinib as a salvage therapy, but the lesions regrew, and the patient died seven months later. Throughout the treatment, he maintained a visual acuity of 0.7 (decimal scale) in both eyes. In conclusion, whole-eye radiation should be considered as a treatment option for the local control of active intraocular lymphoma, especially choroidal lesions, for patients with primary central nervous system lymphoma with no active brain lesions and without systemic treatment. 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=YanoTomofumi en-aut-sei=Yano en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshioKotaro en-aut-sei=Yoshio en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraHirotake en-aut-sei=Nishimura en-aut-mei=Hirotake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=brain biopsy kn-keyword=brain biopsy en-keyword=bruton tyrosine kinase (btk) inhibitor kn-keyword=bruton tyrosine kinase (btk) inhibitor en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=diffuse large b-cell lymphoma kn-keyword=diffuse large b-cell lymphoma en-keyword=fluorodeoxyglucose positron emission tomography kn-keyword=fluorodeoxyglucose positron emission tomography en-keyword=primary central nervous system lymphoma kn-keyword=primary central nervous system lymphoma en-keyword=primary intraocular (vitreoretinal) lymphoma kn-keyword=primary intraocular (vitreoretinal) lymphoma en-keyword=radiation therapy (radiotherapy) kn-keyword=radiation therapy (radiotherapy) en-keyword=tirabrutinib kn-keyword=tirabrutinib en-keyword=whole-eye radiation kn-keyword=whole-eye radiation END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=5 article-no= start-page=164 end-page=173 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nephronophthisis and Retinitis Pigmentosa (Senior-Loken Syndrome) After Living-Donor Kidney Transplantation: Twelve-Year Follow-Up in a Young Woman en-subtitle= kn-subtitle= en-abstract= kn-abstract=Senior-Loken syndrome is a hereditary ciliopathy with recessive trait that manifests as nephronophthisis and retinitis pigmentosa. This report described an 18-year-old woman who was referred to a University Hospital to set up a treatment plan for chronic renal failure of an unknown cause. She had experienced nocturnal polyurea from the age of 12 years and was found to have an elevated level of serum creatinine at 3 mg/dL at the age of 15 years. She underwent renal biopsy at a hometown regional hospital which showed global glomerulosclerosis in six of the 13 glomeruli examined, renal tubular dilation in irregular shape, and marked interstitial fibrosis with lymphocytic infiltration. At the age of 19 years, she received a living-donor kidney transplant from her 46-year-old father as a preemptive therapy. At surgery, biopsy of the father’s donor kidney showed two glomeruli with global sclerosis out of 24 glomeruli examined, in association with minimal interstitial fibrosis and lymphocytic infiltration. She began to have extended-release tacrolimus 4 mg daily and mycophenolate mofetil 1,000 mg daily. According to the standard protocol, she underwent biopsy of the transplanted donor kidney to reveal interstitial fibrosis and lymphocytic infiltration, in addition to no sign of rejection and no glomerular deposition of immunoglobulins and complements, both 4 weeks and 14 months after the kidney transplantation. At the age of 23 years, 4 years after the kidney transplantation, she was, for the first time, diagnosed retinitis pigmentosa, and hence, Senior-Loken syndrome. She was followed up in the stable condition with basal doses of tacrolimus 5 mg daily, mycophenolate mofetil 1,000 mg daily, and prednisolone 5 mg daily up until now in 12 years after the kidney transplantation. The interstitial fibrosis with lymphocytic infiltration in the donor kidney might be a milder presentation of the disease with recessive inheritance. 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=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorinagaHiroshi en-aut-sei=Morinaga en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Urology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Retinitis pigmentosa kn-keyword=Retinitis pigmentosa en-keyword=Nephronophthisis kn-keyword=Nephronophthisis en-keyword=Senior-Loken syndrome kn-keyword=Senior-Loken syndrome en-keyword=Kidney transplantation kn-keyword=Kidney transplantation en-keyword=Living donor kn-keyword=Living donor en-keyword=Kidney biopsy kn-keyword=Kidney biopsy en-keyword=Pathology kn-keyword=Pathology en-keyword=Computed tomography scan kn-keyword=Computed tomography scan en-keyword=Ciliopathy kn-keyword=Ciliopathy en-keyword=Optical coherence tomography kn-keyword=Optical coherence tomography END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=e83484 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detailed Ophthalmic and Pathological Features of Choroidal Metastasis From Breast Cancer: A Case Series of Five Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast cancer causes choroidal metastases on rare occasions. This study presented the eye manifestations of choroidal metastases from breast cancer and their response to treatments in detail as well as their pathological correlation in five patients. The patients' age at the diagnosis of breast cancer ranged from 24 to 69 years (median: 37 years). The time from the diagnosis of breast cancer to the detection of metastases was concurrent in one patient, two years later in three patients, and six years later in the other patient. The time from the detection of systemic metastases to the detection of choroidal metastases was the same in one patient, while it ranged from one to seven years later in four patients. Choroidal metastases were in the unilateral eye of four patients, whereas they were in both eyes of one patient. Choroidal metastases manifested as one or a few nodular or flat choroidal lesions with serous retinal detachment. As for the treatment of choroidal metastases, enucleation of the right eye was chosen based on the patient's wish as well as the family's wish in the earliest patient when cancer notification was not the norm in Japan. In the other four patients, whole-eye radiation was performed to reduce the choroidal metastatic lesions. As regards the prognosis, which was available in four patients, three patients died within one year from the diagnosis of choroidal metastases, while one patient died one year and eight months later. Regarding the pathology of breast cancer, which was available in four patients, immunostaining of the preserved enucleated eye in the earliest patient revealed that breast cancer cells in the choroidal metastatic lesion were positive for estrogen receptor and negative for progesterone receptor and human epidermal growth factor receptor 2 (HER2). Invasive ductal carcinoma in two patients was positive for estrogen receptor and negative for HER2, while invasive ductal carcinoma in the other patient was triple-negative for estrogen receptor, progesterone receptor, and HER2 with a high Ki-67 index. In conclusion, the prognosis for life was poor in patients with breast cancer who developed choroidal metastases. Choroidal metastatic lesions showed a response to whole-eye radiation to improve the quality of vision at the end of life. Vision-related symptoms should be monitored in the course of chemotherapy for systemic metastases. 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=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraokaAtsushi en-aut-sei=Muraoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=choroidal metastasis kn-keyword=choroidal metastasis en-keyword=estrogen receptor kn-keyword=estrogen receptor en-keyword=her2 kn-keyword=her2 en-keyword=immunostaining kn-keyword=immunostaining en-keyword=invasive ductal carcinoma kn-keyword=invasive ductal carcinoma en-keyword=ki-67 kn-keyword=ki-67 en-keyword=progesterone receptor kn-keyword=progesterone receptor en-keyword=radiation kn-keyword=radiation END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue=21 article-no= start-page=13372 end-page=13380 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250520 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unraveling the Molecular Mechanism of Transient Multilamellar Formation in Ethanol-Modified Vesicle Solutions en-subtitle= kn-subtitle= en-abstract= kn-abstract=A recent microfluidic-based small-angle X-ray scattering (SAXS) measurement intriguingly suggested the transient formation of multilamellar structures during the mixing of unilamellar vesicles with ethanol in an aqueous solution. This study explores a possible molecular mechanism underlying this phenomenon, primarily through coarse-grained molecular dynamics (CG-MD) simulations. We first examined lipid aggregate morphology as a function of ethanol concentration in an aqueous solution. Even though vesicles were observed in pure aqueous solution, increasing ethanol concentrations led to more frequent pore formation in vesicular membranes. At ethanol concentrations above 52%, vesicles destabilized and transformed into worm-like micelles. We hypothesized that the transient multilamellar structures might arise from vesicle stacking due to variations in the effective interactions between vesicles. However, a series of potential of mean force (PMF) calculations consistently showed repulsive interactions between vesicles, regardless of ethanol concentration, ruling out this possibility. In contrast, once lipid aggregates transformed into worm-like micelles, the PMF barrier between them dropped (∼5kBT), promoting fusion. Our CG-MD simulations further demonstrated that lipid aggregates (micelles) readily fused and grew in high ethanol concentrations. Upon subsequent exposure to lower ethanol levels, these enlarged aggregates reorganized into vesicles with internal lamellar structure─multilamellar vesicles. These findings suggest that the heterogeneous mixing of unilamellar vesicular solutions with ethanol in a microfluidic device plays a key role in the emergence of transient multilamellar structures. en-copyright= kn-copyright= en-aut-name=ShibataKana en-aut-sei=Shibata en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaekiMasatoshi en-aut-sei=Maeki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokeshiManabu en-aut-sei=Tokeshi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShinodaWataru en-aut-sei=Shinoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Materials Chemistry, Nagoya University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Faculty of Engineering, Hokkaido University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Faculty of Engineering, Hokkaido University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=6 article-no= start-page=e70126 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sulphur‐Acquisition Pathways for Cysteine Synthesis Confer a Fitness Advantage to Bacteria in Plant Extracts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteria and plants are closely associated with human society, in fields such as agriculture, public health, the food industry, and waste disposal. Bacteria have evolved nutrient-utilisation systems adapted to achieve the most efficient growth in their major habitats. However, empirical evidence to support the significance of bacterial nutrient utilisation in adaptation to plants is limited. Therefore, we investigated the genetic and nutritional factors required for bacterial growth in plant extracts by screening an Escherichia coli gene-knockout library in vegetable-based medium. Mutants lacking genes involved in sulphur assimilation, whereby sulphur is transferred from sulphate to cysteine, exhibited negligible growth in vegetable-based medium or plant extracts, owing to the low cysteine levels. The reverse transsulphuration pathway from methionine, another pathway for donating sulphur to cysteine, occurring in bacteria such as Bacillus subtilis, also played an important role in growth in plant extracts. These two sulphur-assimilation pathways were more frequently observed in plant-associated than in animal-associated bacteria. Sulphur-acquisition pathways for cysteine synthesis thus play a key role in bacterial growth in plant-derived environments such as plant residues and plant exudates. en-copyright= kn-copyright= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamaguchiSaki en-aut-sei=Yamaguchi en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukaokaTaketo en-aut-sei=Tsukaoka en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsunodaMakoto en-aut-sei=Tsunoda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Pharmaceutical Sciences, The University of Tokyo kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Bacillus subtilis kn-keyword=Bacillus subtilis en-keyword=bacterial nutrient utilisation kn-keyword=bacterial nutrient utilisation en-keyword=cysteine synthesis kn-keyword=cysteine synthesis en-keyword=Escherichia coli kn-keyword=Escherichia coli en-keyword=plant-derived environments kn-keyword=plant-derived environments en-keyword=sulphur acquisition pathway kn-keyword=sulphur acquisition pathway END start-ver=1.4 cd-journal=joma no-vol=227 cd-vols= no-issue= article-no= start-page=110168 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The hidden cation-selective pore in ion-conducting aquaporin OsPIP2;4 from rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ion-conducting aquaporins (icAQPs) transport ions as well as water. Although the molecular mechanism of how AQPs establish selective permeability for water molecules is well understood, the ion-transporting mechanism in icAQPs has not yet been fully elucidated. In this study, we investigated the molecular mechanism of cation transport in OsPIP2;4, an icAQP in rice, by homology modeling and the electrophysiological analysis using Xenopus laevis oocytes. Water and ion transport assays using OsPIP2;4 T227M and G278K mutants strongly suggested that water- and cation-transporting pathways are independent of each other. Data from amino acid substitutions V54I and A143G in OsPIP2;4 led to the identification of a novel hidden pathway for cation transport located on the side surfaces of the tetramer channel, where two protomers are in contact, which is distinct from conventional monomeric pores and the tetrameric central pore in AQPs. Moreover, the present results provide the possibility that this hypothetical hidden pore also functions in the barley icAQP HvPIP2;8. The overall structure of this novel pathway appears to differ from the structure of general cation channels. However, the arrangement of hydrophilic amino acids at the entrance of the pathway of OsPIP2;4 was found to be comparable to that of some cation channels, which implies that the molecular mechanism of dehydration of hydrated ions might resemble that of the channels. Although direct structural evidence is needed to confirm the proposed pathway, the present study can be a stepping stone toward unraveling the mechanism of dual water and ion transport through icAQPs in plants. en-copyright= kn-copyright= en-aut-name=OnoShuntaro en-aut-sei=Ono en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TranSen Thi Huong

deep-sea hydrothermal vent shrimp Rimicaris hybisae en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unlike terrestrial environments, where humans reside, there is no sunlight in the deep sea. Instead, dim visible light from black-body radiation and bioluminescence illuminates hydrothermal vent areas in the deep sea. A deep-sea hydrothermal vent shrimp, Rimicaris hybisae, is thought to detect this dim light using its enlarged dorsal eye; however, the molecular basis of its photoreception remains unexplored. Here, we characterized the molecular properties of opsins, universal photoreceptive proteins in animals, found in R. hybisae. Transcriptomic analysis identified six opsins: three Gq-coupled opsins, one Opn3, one Opn5, and one peropsin. Functional analysis revealed that five of these opsins exhibited light-dependent G protein activity, whereas peropsin exhibited the ability to convert all-trans-retinal to 11-cis-retinal like photoisomerases. Notably, all the R. hybisae opsins, including Opn5, convergently show visible light sensitivity (around 457–517 nm), whereas most opsins categorized as Opn5 have been demonstrated to be UV sensitive. Mutational analysis revealed that the unique visible light sensitivity of R. hybisae Opn5 is achieved through the stabilization of a protonated Schiff base by a counterion residue at position 83 (Asp83), which differs from the position identified in other opsins. These findings suggest that the vent shrimp R. hybisae has adapted its photoreceptive devices to dim deep-sea hydrothermal light by selectively maintaining a repertoire of visible light–sensitive opsins, including the uniquely tuned Opn5. en-copyright= kn-copyright= en-aut-name=NagataYuya en-aut-sei=Nagata en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

for Subtyping Idiopathic Multicentric Castleman Disease Based on Machine Learning Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Idiopathic multicentric Castleman disease (iMCD) is a rare lymphoproliferative disorder classified into three recognized clinical subtypes—idiopathic plasmacytic lymphadenopathy (IPL), TAFRO, and NOS. Although clinical criteria are available for subtyping, diagnostically challenging cases with overlapping histopathological features highlight the need for an improved classification system integrating clinical and histopathological findings. We aimed to develop an objective histopathological subtyping system for iMCD that closely correlates with the clinical subtypes. Excisional lymph node specimens from 94 Japanese iMCD patients (54 IPL, 28 TAFRO, 12 NOS) were analyzed for five key histopathological parameters: germinal center (GC) status, plasmacytosis, vascularity, hemosiderin deposition, and “whirlpool” vessel formation in GC. Using hierarchical clustering, we visualized subgroups and developed a machine learning-based decision tree to differentiate the clinical subtypes and validated it in an external cohort of 12 patients with iMCD. Hierarchical cluster analysis separated the IPL and TAFRO cases into mutually exclusive clusters, whereas the NOS cases were interspersed between them. Decision tree modeling identified plasmacytosis, vascularity, and whirlpool vessel formation as key features distinguishing IPL from TAFRO, achieving 91% and 92% accuracy in the training and test sets, respectively. External validation correctly classified all IPL and TAFRO cases, confirming the reproducibility of the system. Our histopathological classification system closely aligns with the clinical subtypes, offering a more precise approach to iMCD subtyping. It may enhance diagnostic accuracy, guide clinical decision-making for predicting treatment response in challenging cases, and improve patient selection for future research. Further validation of its versatility and clinical utility is required. en-copyright= kn-copyright= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaratakeTomoka en-aut-sei=Haratake en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SumiyoshiRemi en-aut-sei=Sumiyoshi en-aut-mei=Remi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UjiieHideki en-aut-sei=Ujiie en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawaharaYuri en-aut-sei=Kawahara en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KogaTomohiro en-aut-sei=Koga en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UekiMasao en-aut-sei=Ueki en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LaczkoDorottya en-aut-sei=Laczko en-aut-mei=Dorottya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OksenhendlerEric en-aut-sei=Oksenhendler en-aut-mei=Eric kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FajgenbaumDavid C. en-aut-sei=Fajgenbaum en-aut-mei=David C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=van RheeFrits en-aut-sei=van Rhee en-aut-mei=Frits kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KawakamiAtsushi en-aut-sei=Kawakami en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health 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 Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=The Research Program for Intractable Disease by Ministry of Health, Labor and Welfare, Castleman Disease, TAFRO and Related Ddisease Research Group kn-affil= affil-num=6 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=The Research Program for Intractable Disease by Ministry of Health, Labor and Welfare, Castleman Disease, TAFRO and Related Ddisease Research Group kn-affil= affil-num=9 en-affil=School of Information and Data Sciences, Nagasaki University kn-affil= affil-num=10 en-affil=Department of Pathology and Laboratory Medicine, Hospital of the University of Pennsylvania kn-affil= affil-num=11 en-affil=Department of Clinical Immunology, Hôpital Saint-Louis kn-affil= affil-num=12 en-affil=Center for Cytokine Storm Treatment and Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=13 en-affil=Myeloma Center, University of Arkansas for Medical Sciences kn-affil= affil-num=14 en-affil=The Research Program for Intractable Disease by Ministry of Health, Labor and Welfare, Castleman Disease, TAFRO and Related Ddisease Research Group kn-affil= affil-num=15 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=clinical subtype kn-keyword=clinical subtype en-keyword=histopathological criteria kn-keyword=histopathological criteria en-keyword=idiopathic multicentric castleman disease kn-keyword=idiopathic multicentric castleman disease en-keyword=lymphoproliferative disease kn-keyword=lymphoproliferative disease en-keyword=machine-learning kn-keyword=machine-learning END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transformation of α,β-Unsaturated Aldehydes with a Small Amount of Electricity: Cyanosilylation, Isomerization, and Nucleophilic Addition en-subtitle= kn-subtitle= en-abstract= kn-abstract=An electrochemical method was developed to convert α,β-unsaturated aldehydes into carboxylic acid derivatives via cyanosilylation, isomerization, and nucleophilic addition.

Here, we report on a very high prevalence (100%) of potential virus-associated double-stranded RNA (dsRNA) elements for a collection of 39 fungal strains of R. solani from the rice sheath blight samples from at least four major rice-growing areas in the Philippines and a reference isolate from the International Rice Research Institute, showing different colony phenotypes. Their dsRNA profiles suggested the presence of multiple viral infections among these Philippine R. solani populations. Using next-generation sequencing, the viral sequences of the three representative R. solani strains (Ilo-Rs-6, Tar-Rs-3, and Tar-Rs-5) from different rice-growing areas revealed the presence of at least 36 viruses or virus-like agents, with the Tar-Rs-3 strain harboring the largest number of viruses (at least 20 in total). These mycoviruses or their candidates are believed to have single-stranded RNA or dsRNA genomes and they belong to or are associated with the orders Martellivirales, Hepelivirales, Durnavirales, Cryppavirales, Ourlivirales, and Ghabrivirales based on their coding-complete RNA-dependent RNA polymerase sequences. The complete genome sequences of two novel RNA viruses belonging to the proposed family Phlegiviridae and family Mitoviridae were determined. en-copyright= kn-copyright= en-aut-name=UrzoMichael Louie R. en-aut-sei=Urzo en-aut-mei=Michael Louie R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GuintoTimothy D. en-aut-sei=Guinto en-aut-mei=Timothy D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Eusebio-CopeAna en-aut-sei=Eusebio-Cope en-aut-mei=Ana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BudotBernard O. en-aut-sei=Budot en-aut-mei=Bernard O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanoriaMary Jeanie T. en-aut-sei=Yanoria en-aut-mei=Mary Jeanie T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JonsonGilda B. en-aut-sei=Jonson en-aut-mei=Gilda B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ArakawaMasao en-aut-sei=Arakawa en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Microbiology Division, Institute of Biological Sciences, College of Arts and Sciences, University of the Philippines Los Baños kn-affil= affil-num=2 en-affil=Microbiology Division, Institute of Biological Sciences, College of Arts and Sciences, University of the Philippines Los Baños kn-affil= affil-num=3 en-affil=Fit-for-Future Genetic Resources Unit, Rice Breeding Innovations Department, International Rice Research Institute (IRRI), University of the Philippines Los Baños kn-affil= affil-num=4 en-affil=Institute of Weed Science, Entomology, and Plant Pathology, College of Agriculture and Food Science, University of the Philippines Los Baños kn-affil= affil-num=5 en-affil=Traits for Challenged Environments Unit, Rice Breeding Innovations Department, International Rice Research Institute (IRRI), University of the Philippines Los Baños kn-affil= affil-num=6 en-affil=Traits for Challenged Environments Unit, Rice Breeding Innovations Department, International Rice Research Institute (IRRI), University of the Philippines Los Baños kn-affil= affil-num=7 en-affil=Faculty of Agriculture, Meijo University kn-affil= affil-num=8 en-affil=Plant-Microbe Interactions Group, Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=9 en-affil=Plant-Microbe Interactions Group, Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Rhizoctonia solani kn-keyword=Rhizoctonia solani en-keyword=dsRNA kn-keyword=dsRNA en-keyword=mycovirus kn-keyword=mycovirus en-keyword=RNA virus kn-keyword=RNA virus en-keyword=metatranscriptome kn-keyword=metatranscriptome END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=12 article-no= start-page=3780 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250617 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Sampling Frequency on Human Activity Recognition with Machine Learning Aiming at Clinical Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Human activity recognition using wearable accelerometer data can be a useful digital biomarker for severity assessment and the diagnosis of diseases, where the relationship between onset and patient activity is crucial. For long-term monitoring in clinical settings, the volume of data collected over time should be minimized to reduce power consumption, computational load, and communication volume. This study aimed to determine the lowest sampling frequency that maintains recognition accuracy for each activity. Thirty healthy participants wore nine-axis accelerometer sensors at five body locations and performed nine activities. Machine-learning-based activity recognition was conducted using data sampled at 100, 50, 25, 20, 10, and 1 Hz. Data from the non-dominant wrist and chest, which have previously shown high recognition accuracy, were used. Reducing the sampling frequency to 10 Hz did not significantly affect the recognition accuracy for either location. However, lowering the frequency to 1 Hz decreases the accuracy of many activities, particularly brushing teeth. Using data with a 10 Hz sampling frequency can maintain recognition accuracy while decreasing data volume, enabling long-term patient monitoring and device miniaturization for clinical applications. en-copyright= kn-copyright= en-aut-name=YamaneTakahiro en-aut-sei=Yamane en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraMoeka en-aut-sei=Kimura en-aut-mei=Moeka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=wearable devices kn-keyword=wearable devices en-keyword=machine learning kn-keyword=machine learning en-keyword=human activity recognition kn-keyword=human activity recognition en-keyword=sampling frequency kn-keyword=sampling frequency en-keyword=digital health kn-keyword=digital health en-keyword=digital biomarkers kn-keyword=digital biomarkers END start-ver=1.4 cd-journal=joma no-vol=166 cd-vols= no-issue=8 article-no= start-page=bqaf102 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neuromedin U Deficiency Disrupts Daily Testosterone Fluctuation and Reduces Wheel-running Activity in Rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=The objective of this study was to elucidate the role of endogenous Neuromedin U (NMU) in rats by performing NMU knockout (KO). Male, but not female NMU KO rats exhibited decreased wheel-running activity vs wildtype (WT), although overall home cage activity was not affected. Plasma testosterone in WT rats varied significantly over the course of a day, with a peak at ZT1 and a nadir at ZT18, whereas in NMU KO rats testosterone remained stable throughout the day. Chronic administration of testosterone restored wheel-running activity in NMU KO rats to the same level as in WT rats, suggesting that the decrease in wheel-running activity in NMU KO rats is due to the disruption of the diurnal change of testosterone. Accordingly, expression of the luteinizing hormone beta subunit (Lhb) mRNA in the pars distalis of anterior pituitary was significantly lower in NMU KO rats; immunostaining revealed that the size of luteinizing hormone (LH)–expressing cells was also relatively small in those animals. In the brain of male WT rats, Nmu was highly expressed in the pars tuberalis, and the NMU receptor Nmur2 was highly expressed in the ependymal cell layer of the third ventricle. This study reveals a novel function of NMU and indicates that endogenous NMU in rats plays a role in the regulation of motivated activity via regulation of testosterone. en-copyright= kn-copyright= en-aut-name=OtsukaMai en-aut-sei=Otsuka en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiYu en-aut-sei=Takeuchi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyamaMaho en-aut-sei=Moriyama en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EgoshiSakura en-aut-sei=Egoshi en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotoYuki en-aut-sei=Goto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GuTingting en-aut-sei=Gu en-aut-mei=Tingting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimuraAtsushi P en-aut-sei=Kimura en-aut-mei=Atsushi P kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HaraguchiShogo en-aut-sei=Haraguchi en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakeuchiSakae en-aut-sei=Takeuchi en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuyamaMakoto en-aut-sei=Matsuyama en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=BentleyGeorge E en-aut-sei=Bentley en-aut-mei=George E kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AizawaSayaka en-aut-sei=Aizawa en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biology, Faculty of Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of 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=Department of Biological Sciences, Faculty of Science, Hokkaido University kn-affil= affil-num=8 en-affil=Department of Biochemistry, Showa University School of Medicine kn-affil= affil-num=9 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Division of Molecular Genetics, Shigei Medical Research Institute kn-affil= affil-num=12 en-affil=Department of Integrative Biology and Helen Wills Neuroscience Institute, University of California at Berkeley kn-affil= affil-num=13 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Neuromedin U kn-keyword=Neuromedin U en-keyword=rat kn-keyword=rat en-keyword=motivation kn-keyword=motivation en-keyword=activity kn-keyword=activity en-keyword=testosterone kn-keyword=testosterone en-keyword=wheel-running kn-keyword=wheel-running END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=2 article-no= start-page=232 end-page=243 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcomes of allogeneic SCT versus tisagenlecleucel in patients with R/R LBCL and poor prognostic factors en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the efficacy of tisagenlecleucel (tisa-cel) and allogeneic hematopoietic stem cell transplantation (allo-SCT) for patients with relapsed and/or refractory (r/r) large B-cell lymphoma (LBCL) with poor prognostic factors, defined as performance status (PS) ≥ 2, multiple extranodal lesions (EN), chemorefractory disease, or higher lactate dehydrogenase (LDH). Overall, the allo-SCT group demonstrated worse progression-free survival (PFS), higher non-relapse mortality, and a similar relapse/progression rate. Notably, the tisa-cel group showed better PFS than the allo-SCT group among patients with chemorefractory disease (3.2 vs. 2.0 months, p = 0.092) or higher LDH (4.0 vs. 2.0 months, p = 0.018), whereas PFS in the two cellular therapy groups was similar among those with PS ≥ 2 or multiple EN. Survival time after relapse post-cellular therapy in patients with poor prognostic factors was 1.6 with allo-SCT and 4.6 months with tisa-cel. These findings were confirmed in a propensity score matching cohort. In conclusion, tisa-cel resulted in better survival than allo-SCT in patients with poor prognostic factors. However, patients who relapsed post-cellular therapy had dismal outcomes regardless of therapy. Further strategies are warranted to improve outcomes in these patients. en-copyright= kn-copyright= en-aut-name=HayashinoKenta en-aut-sei=Hayashino en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeraoToshiki en-aut-sei=Terao en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHiroki en-aut-sei=Kobayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamoiChihiro en-aut-sei=Kamoi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=11 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=13 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=14 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= en-keyword=Large B-cell lymphoma kn-keyword=Large B-cell lymphoma en-keyword=Allogeneic hematopoietic stem cell transplantation kn-keyword=Allogeneic hematopoietic stem cell transplantation en-keyword=CAR-T cell therapy kn-keyword=CAR-T cell therapy en-keyword=Tisagenlecleucel kn-keyword=Tisagenlecleucel en-keyword=Poor prognostic factors kn-keyword=Poor prognostic factors END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=5 article-no= start-page=759 end-page=762 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Novel De Novo Variant in KCNH5 in a Patient with Refractory Epileptic Encephalopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=We herein report a novel de novo KCNH5 variant in a patient with refractory epileptic encephalopathy. The patient exhibited seizures at 1 year and 7 months old, which gradually worsened, leading to a bedridden status. Brain magnetic resonance imaging (MRI) showed cerebral atrophy and cerebellar hypoplasia. A trio whole-exome sequence analysis identified a de novo heterozygous c.640A>C, p.Lys214Gln variant in KCNH5 that was predicted to be deleterious. Recent studies have linked KCNH5 to various epileptic encephalopathies, with many patients showing normal MRI findings. The present case expands the clinical spectrum of the disease, as it is characterized by severe neurological prognosis, cerebral atrophy, and cerebellar hypoplasia. en-copyright= kn-copyright= en-aut-name=MitsutakeAkihiko en-aut-sei=Mitsutake en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukawaTakashi en-aut-sei=Matsukawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaitoTatsuhiko en-aut-sei=Naito en-aut-mei=Tatsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitsuiJun en-aut-sei=Mitsui en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaHiroaki en-aut-sei=Harada en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujioKeishi en-aut-sei=Fujio en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujishiroJun en-aut-sei=Fujishiro en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriHarushi en-aut-sei=Mori en-aut-mei=Harushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MorishitaShinichi en-aut-sei=Morishita en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsujiShoji en-aut-sei=Tsuji en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TodaTatsushi en-aut-sei=Toda en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=2 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=4 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=6 en-affil=Department of Rheumatology and Allergy, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Rheumatology and Allergy, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=8 en-affil=Department of Pediatric Surgery, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=9 en-affil=Department of Radiology, School of Medicine, Jichi Medical University kn-affil= affil-num=10 en-affil=Department of Computational Biology and Medical Sciences, Graduate School of Frontier Sciences, The University of Tokyo kn-affil= affil-num=11 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=12 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= en-keyword=epileptic encephalopathy kn-keyword=epileptic encephalopathy en-keyword=whole-exome sequencing kn-keyword=whole-exome sequencing en-keyword=KCNH5 kn-keyword=KCNH5 en-keyword=de novo variant kn-keyword=de novo variant END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recent progress in oculopharyngodistal myopathy research from clinical and genetic viewpoints en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oculopharyngodistal myopathy (OPDM) is a rare muscular disorder characterized by ocular symptoms, pharyngeal symptoms, facial weakness, and distal predominant limb muscle weakness. The cause of the disease was unknown for a long time. Recently, however, it has been reported that expansions of CGG or CCG repeats in LRP12, LOC642361/NUTM2B-AS1, GIPC1, NOTCH2NLC, RILPL1, and ABCD3 are the causes of the disease. Cases sometimes present with neurological symptoms, and the clinical spectrum of diseases caused by expansions of CGG or CCG repeats has been proposed to be called FNOP-spectrum disorder after the names of fragile X-associated tremor/ataxia syndrome, neuronal intranuclear inclusion disease, oculopharyngeal myopathy with leukoencephalopathy, and OPDM. In this article, the recent progress in the field of OPDM is reviewed, and remaining issues in OPDM are discussed. en-copyright= kn-copyright= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=oculopharyngodistal myopathy kn-keyword=oculopharyngodistal myopathy en-keyword=CGG repeat kn-keyword=CGG repeat en-keyword=CCG repeat kn-keyword=CCG repeat en-keyword=repeat motif–phenotype correlation kn-keyword=repeat motif–phenotype correlation en-keyword=FNOP-spectrum disorder kn-keyword=FNOP-spectrum disorder END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=5602-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Two Cases of Autosomal Recessive Spinocerebellar Ataxia-8 Showing Two Novel Variants of SYNE1 in Japanese Families en-subtitle= kn-subtitle= en-abstract= kn-abstract=Autosomal recessive spinocerebellar ataxia-8 (SCAR8) is a neurodegenerative disorder caused by the biallelic pathogenic variants of SYNE1.

Pathogenic variants of SYNE1 cause various symptoms, including cerebellar ataxia, pyramidal tract disorders, and joint disorders, and the pathogenic variants discovered in this study were located in a region prone to cerebellar ataxia. en-copyright= kn-copyright= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuokaChika en-aut-sei=Matsuoka en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsakadaYosuke en-aut-sei=Osakada en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukuiYusuke en-aut-sei=Fukui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakemotoMami en-aut-sei=Takemoto en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=SCAR8 kn-keyword=SCAR8 en-keyword=SCAR kn-keyword=SCAR en-keyword=cerebellar ataxia kn-keyword=cerebellar ataxia en-keyword=whole-exome sequencing analysis kn-keyword=whole-exome sequencing analysis END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=6 article-no= start-page=388.e1 end-page=388.e14 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical effects of granulocyte colony-stimulating factor administration and the timing of its initiation on allogeneic hematopoietic cell transplantation outcomes for myelodysplastic syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granulocyte colony-stimulating factor (G-CSF) accelerates neutrophil recovery after allogeneic hematopoietic cell transplantation (HCT). However, the optimal use of G-CSF and the timing of its initiation after allogeneic HCT for myelodysplastic syndrome (MDS) according to graft type have not been determined. This retrospective study aimed to investigate the effects of using G-CSF administration and the timing of its initiation on transplant outcomes in adult patients with MDS undergoing allogeneic HCT. Using Japanese registry data, we retrospectively investigated the effects of G-CSF administration and the timing of its initiation on transplant outcomes among 4140 adults with MDS after bone marrow transplantation (BMT), peripheral blood stem cell transplantation (PBSCT), or single-unit cord blood transplantation (CBT) between 2013 and 2022. Multivariate analysis showed that early (days 0 to 4) and late (days 5 to 10) G-CSF administration significantly accelerated neutrophil recovery compared with no G-CSF administration following BMT, PBSCT, and CBT, but there was no benefit of early G-CSF initiation for early neutrophilic recovery regardless of graft type. Late G-CSF initiation was significantly associated with a higher risk of overall chronic GVHD following PBSCT (hazard ratio [HR], 1.63; 95% confidence interval [CI], 1.18 to 2.24; P = .002) and CBT (HR, 2.09; 95% CI, 1.21 to 3.60; P = .007) compared with no G-CSF administration. Late G-CSF initiation significantly improved OS compared with no G-CSF administration only following PBSCT (HR, 0.74; 95% CI, 0.58 to 0.94; P = .015). However, G-CSF administration and the timing of its initiation did not affect acute GVHD, relapse, or non-relapse mortality, irrespective of graft type. These results suggest that G-CSF administration significantly accelerated neutrophil recovery after BMT, PBSCT, and CBT, but increased risk of overall chronic GVHD after PBSCT and CBT. However, the effect of early and late G-CSF initiation on transplant outcomes needs further study in adult patients with MDS. en-copyright= kn-copyright= en-aut-name=KonumaTakaaki en-aut-sei=Konuma

as an anatomical trochlear pulley system within the human body, challenging the traditional understanding of trochlear systems. While widely recognized trochlear units include structures like the medial part of the humerus and the superior oblique muscle of the orbit, the review focuses on the unique anatomical arrangement of the intermediate tendon of the digastric muscle in connection with the anterior and posterior bellies of the digastric muscles. Despite current debates within the anatomical community about labeling the digastric muscles as having a trochlea, this paper delves into the scientific definition of a trochlear pulley system, presenting the intermediate tendon of the digastric muscle as a potential trochlea. en-copyright= kn-copyright= en-aut-name=du PlooyXander en-aut-sei=du Plooy en-aut-mei=Xander kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CardonaJuan J. en-aut-sei=Cardona en-aut-mei=Juan J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TabiraYoko en-aut-sei=Tabira en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BubbKathleen Carol en-aut-sei=Bubb en-aut-mei=Kathleen Carol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RaeburnKazzara en-aut-sei=Raeburn en-aut-mei=Kazzara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=IwanagaJoe en-aut-sei=Iwanaga en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TubbsR.

We extract frequency- and time-resolved spatial mode patterns and k-space images, together with dispersion relations. We investigate the conditions required for robust propagation along interfaces and thereby observe very high efficiency waveguiding. en-copyright= kn-copyright= en-aut-name=OtsukaP.

Stomatal closure could be a plant response to mitigate SO2 damage, although the mechanism for SO2-induced closure remains controversial. Proposed mediators for SO2-induced stomatal closure include phytohormones, reactive oxygen species, gasotransmitters, and cytosolic acidification. In this study, we investigated the mechanism of stomatal closure in Arabidopsis in response to SO2. Despite an increment in auxin and jasmonates after SO2 exposure, the addition of auxin did not cause stomatal closure and jasmonate-insensitive mutants exhibited SO2-induced stomatal closure suggesting auxin and jasmonates are not mediators leading to the closure. In addition, supplementation of scavenging reagents for reactive oxygen species and gasotransmitters did not inhibit SO2-induced closure. Instead, we found that cytosolic acidification is a credible mechanism for SO2-induced stomatal closure in Arabidopsis. CLCa mutants coding H+/nitrate antiporter, involved in cytosolic pH homeostasis, showed less sensitive stomatal phenotype against SO2. These results suggest that cytosolic pH homeostasis plays a tenable role in SO2 response in guard cells. en-copyright= kn-copyright= en-aut-name=OoiLia en-aut-sei=Ooi en-aut-mei=Lia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= 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=3 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=airborne pollutants kn-keyword=airborne pollutants en-keyword=cytosolic acidification kn-keyword=cytosolic acidification en-keyword=stomatal closure kn-keyword=stomatal closure en-keyword=sulfur dioxide kn-keyword=sulfur dioxide END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=32 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stability and water solubility of calcium ferrite-type aluminum-rich phase: implications for deep water cycle caused by subducting basaltic crusts en-subtitle= kn-subtitle= en-abstract= kn-abstract=The subducting crustal materials serve as a crucial channel for transporting water to the lower mantle. Recent experimental studies suggest that crustal materials such as basaltic crust can be a main water carrier and reservoir playing an important role on water cycling in the lower mantle. Despite being a primary mineral in crustal materials, the water solubility of calcium ferrite-type (CF) phase and its stability are unclear yet. A recent phase relation study of hydrous basalts showed Na-depletion in lower-mantle minerals, suggesting the presence of fluid possibly with high Na concentration and the absence of CF phase along the low-temperature slab geotherms, where Al-rich hydrous phase H and ferropericlase appear instead. These phases could consequently produce Na-depleted CF phase when reaching the dehydration temperature of Al-rich hydrous phase H. In this study, we investigated the stability and water solubility of CF-type MgAl2O4, which is a main CF component in a hydrous basalt, in water-bearing systems at 26–32 GPa and 1200–1900 °C using a Kawai-type multi-anvil press. Our results indicate that the stability of the CF phase is strongly influenced by water content in the system. Water contents of recovered CF phases estimated by Fourier-transform infrared spectroscopy show a limited variation between 73 and 87 ppm wt at a pressure of 26 GPa and temperatures of 1500–1900 °C. We suggest that CF phase could not be a primary water carrier at lower mantle depths. This emphasizes contributions of hydrous aluminous silica minerals to Earth’s deep water cycling and heterogeneous structures in the lower mantle due to the strong water partitioning to this phase compared with other constituent minerals. en-copyright= kn-copyright= en-aut-name=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MashinoIzumi en-aut-sei=Mashino en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Deep Space Exploration Laboratory/School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Water solubility kn-keyword=Water solubility en-keyword=CF phase kn-keyword=CF phase en-keyword=Single crystal kn-keyword=Single crystal en-keyword=FTIR kn-keyword=FTIR en-keyword=MORB kn-keyword=MORB END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=5 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=In-frame deletion variant of ABCD1 in a sporadic case of adrenoleukodystrophy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Adrenoleukodystrophy (ALD), an X-linked leukodystrophy caused by pathogenic variants in ABCD1, exhibits a broad range of phenotypes from childhood-onset cerebral forms to adult-onset adrenomyeloneuropathy (AMN).

This study introduces a novel method for quantitative QC of the system, utilizing MV images and webcam videos. The stability of the motor drive speed and the positional accuracy of the fixture were evaluated under two measurement modes: “continuous mode” and “step-by-step mode.”
Methods: A TRUFIX mounting system (PTW Freiburg Inc., Germany) was used to attach the center of the steel ball to its top, ensuring alignment with the water surface of the tank. To assess deviations from the radiation isocenter, MV images were acquired and compared with digitally reconstructed radiographs (DRRs). These evaluations were performed at different speed settings (slow, medium, and fast) using ET CT Body Marker (BRAINLAB Inc., USA) mounted on the drive unit. A webcam was utilized to capture the images, and custom-developed tracking software was employed to analyze deviations in driving speed and positional errors.
Results: The mean error of the radiation isocenter was 0.37 ± 0.09 mm. As the motor drive speed increased, the discrepancy between the set speed and the actual speed observed in the analysis also became larger. In “continuous mode,” the deviation from the displayed value was greater than that observed in “step-by-step mode.”
Conclusion: It is demonstrated that the proposed analysis method can quantitatively evaluate radiation isocenter misalignment, tank setup position deviation, and both the indicated drive speed values and their stability. At higher drive speeds, the “step-by-step mode” showed smaller deviations from the indicated values. en-copyright= kn-copyright= en-aut-name=TanimotoYuki en-aut-sei=Tanimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoshiKazunobu en-aut-sei=Koshi en-aut-mei=Kazunobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiroshigeAkira en-aut-sei=Hiroshige en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaShohei en-aut-sei=Yoshida en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujitaYoshiki en-aut-sei=Fujita en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakahiraAtsuki en-aut-sei=Nakahira en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanishiDaiki en-aut-sei=Nakanishi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HondaHirofumi en-aut-sei=Honda en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, NHO Kure Medical Center and Chugoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=3 en-affil=Department of Radiology, NHO Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Division of Radiology, Department of Medical Technology, Kyushu University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Ehime University Hospital kn-affil= affil-num=10 en-affil=Department of Healthcare Science, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=3D water tank kn-keyword=3D water tank en-keyword=drive speed stability kn-keyword=drive speed stability en-keyword=quality control kn-keyword=quality control en-keyword=radiation isocenter kn-keyword=radiation isocenter en-keyword=x-ray image analysis kn-keyword=x-ray image analysis END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=78 end-page=85 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Standardization of radiation therapy quality control system through mutual quality control based on failure mode and effects analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The advancement of irradiation technology has increased the demand for quality control of radiation therapy equipment. Consequently, the number of quality control items and required personnel have also increased. However, differences in the proportion of qualified personnel to irradiation techniques have caused bias in quality control systems among institutions. To standardize the quality across institutions, researchers should conduct mutual quality control by analyzing the quality control data of one institution at another institution and comparing the results with those of their own institutions. This study uses failure mode and effects analysis (FMEA) to identify potential risks in 12 radiation therapy institutions, compares the results before and after implementation of mutual quality control, and examines the utility of mutual quality control in risk reduction. Furthermore, a cost-effectiveness factor is introduced into FMEA to evaluate the utility of mutual quality control. en-copyright= kn-copyright= en-aut-name=TanimotoYuki en-aut-sei=Tanimoto

variation small-angle neutron scattering via Gaussian process regression with prior knowledge of smoothness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Contrast variation small-angle neutron scattering (CV-SANS) is a powerful tool for evaluating the structure of multi-component systems. In CV-SANS, the scattering intensities I(Q) measured with different scattering contrasts are de­com­posed into partial scattering functions S(Q) of the self- and cross-correlations between components. Since the measurement has a measurement error, S(Q) must be estimated statistically from I(Q). If no prior knowledge about S(Q) is available, the least-squares method is best, and this is the most popular estimation method. However, if prior knowledge is available, the estimation can be improved using Bayesian inference in a statistically authorized way. In this paper, we propose a novel method to improve the estimation of S(Q), based on Gaussian process regression using prior knowledge about the smoothness and flatness of S(Q). We demonstrate the method using synthetic core–shell and experimental polyrotaxane SANS data. en-copyright= kn-copyright= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyajimaShinya en-aut-sei=Miyajima en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKazuaki en-aut-sei=Tanaka en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MayumiKoichi en-aut-sei=Mayumi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Science and Engineering, Iwate University kn-affil= affil-num=3 en-affil=Global Center for Science and Engineering, Waseda University kn-affil= affil-num=4 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= en-keyword=contrast variation small-angle neutron scattering kn-keyword=contrast variation small-angle neutron scattering en-keyword=CV-SANS kn-keyword=CV-SANS en-keyword=partial scattering functions kn-keyword=partial scattering functions en-keyword=multi-component systems kn-keyword=multi-component systems en-keyword=statistical methods kn-keyword=statistical methods en-keyword=Bayesian inference kn-keyword=Bayesian inference en-keyword=contrast variation kn-keyword=contrast variation en-keyword=Gaussian process regression kn-keyword=Gaussian process regression END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Leg-biting fights reduce the number of sperm transferred by the loser and in draws in Zophobas atratus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intra-sexual selection has been observed across a wide range of species. Male-male combat can not only determine the winner and loser but also affect subsequent reproductive success. The effects of combat outcomes on reproduction are thought to depend on the reproductive ecology of the target species. However, to our knowledge, studies examining the impact of combat outcomes on sperm competition and fitness remain limited. In the giant mealworm (Zophobas atratus), male’s combat involves biting each other's hind legs. Females mated to the losers of leg-biting contests had significantly fewer eggs and fewer offspring than females mated to males that were not in a contest. Possible explanations for this fitness reduction include the inability of males to transfer sperm effectively due to the combat outcome or the inability of their sperm to fertilize eggs due to female cryptic sperm choice, and the mechanisms underlying this reduction remain unclear. Previous studies have observed distorted mating postures in losing males, leading us to hypothesize that leg-biting during combat might affect sperm transfer. To test this, we allowed uncontested males, winners, losers, and males with a draw outcome to mate with females and compared the number of sperm within the female’s spermatheca. Additionally, we examined the correlation between combat duration and sperm count. Results showed that losers and males with draw transferred fewer sperm than non-combat males. Moreover, the longer the combat duration, the fewer sperm males were able to transfer. These findings suggest that the reduction in sperm transferred was affected by both losing in combat and prolonged combat duration in leg-biting encounters. en-copyright= kn-copyright= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Male combat kn-keyword=Male combat en-keyword=Male-male competition kn-keyword=Male-male competition en-keyword=Sperm transfer kn-keyword=Sperm transfer en-keyword=Sperm biology kn-keyword=Sperm biology END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=5 article-no= start-page=733 end-page=747 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A PRA-Rab trafficking machinery modulates NLR immune receptor plasma membrane microdomain anchoring and blast resistance in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nucleotide-binding leucine-rich repeat (NLR) receptors mediate pathogen effector-triggered immunity (ETI) in plants, and a subclass of NLRs are hypothesized to function at the plasma membrane (PM). However, how NLR traffic and PM delivery are regulated during immune responses remains largely unknown. The rice NLR PigmR confers broad-spectrum resistance to the blast fungus Magnaporthe oryzae. Here, we report that a PRA (Prenylated Rab acceptor) protein, PIBP4 (PigmR-INTERACTING and BLAST RESISTANCE PROTEIN 4), interacts with both PigmR and the active form of the Rab GTPase, OsRab5a, thereby loads a portion of PigmR on trafficking vesicles that target to PM microdomains. Microdomain-localized PigmR interacts with and activates the small GTPase OsRac1, which triggers reactive oxygen species signaling and hypersensitive response, leading to immune responses against blast infection. Thus, our study discovers a previously unknown mechanism that deploys a PRA-Rab protein delivering hub to ensure ETI, linking the membrane trafficking machinery with NLR function and immune activation in plants. en-copyright= kn-copyright= en-aut-name=LiangDi en-aut-sei=Liang en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YangDongyong en-aut-sei=Yang

materials have unique structures that can be modified by adjusting the space between layers through pillaring or surface functionalization. Unlike typical crystalline layered materials, graphene oxide (GO) possesses reactive oxygenated functional groups, which lead to spontaneous reduction and stacking upon thermal treatment. Here, we investigated the functionalization of GO with different amounts of hexylamine to control the degree of surface coverage. Furthermore, octylamine and dodecylamine were employed to confirm the effect of the alkyl chain length on the interlayer distance of the resultant GO derivatives. Subsequent thermal treatment produced reduced GO (rGO) functionalized with alkylamines, demonstrating the retention of the interlayer distance. Additionally, amine-functionalized rGOs exhibited varying porous structures. en-copyright= kn-copyright= en-aut-name=Ortiz-AnayaIsrael en-aut-sei=Ortiz-Anaya en-aut-mei=Israel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataSeiji en-aut-sei=Obata en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Sciences and Technology, 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= en-keyword=Graphene oxide kn-keyword=Graphene oxide en-keyword=Layered material kn-keyword=Layered material en-keyword=Interlayer distance kn-keyword=Interlayer distance en-keyword=Functionalization kn-keyword=Functionalization en-keyword=Alkylamines kn-keyword=Alkylamines en-keyword=Nitrogen physisorption kn-keyword=Nitrogen physisorption END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The maxillary vein: an anatomical narrative review with clinical implications for oral and maxillofacial surgeons en-subtitle= kn-subtitle= en-abstract= kn-abstract=The maxillary vein, despite its clinical significance, remains underexplored in anatomical literature. It plays a crucial role in venous drainage of the maxillofacial region and is closely associated with surgical procedures such as sagittal split ramus osteotomy, mandibuloplasty, and condylar or parotid surgeries. Due to its variable anatomy and proximity to critical structures, the maxillary vein poses a risk of significant hemorrhage if injured. Its small size and deep location make preoperative identification challenging, especially without contrast-enhanced imaging. Embryologically, the maxillary vein originates from the primitive maxillary vein and develops through complex anastomoses with other craniofacial veins. Anatomical studies have revealed several variations, including the presence of accessory mandibular foramina and unusual venous connections, which may increase surgical risk. Understanding the detailed anatomy and potential variations of the maxillary vein is essential for minimizing complications and improving surgical outcomes. Despite its importance, more anatomical and clinical research is needed to better define its course, variations, and implications in oral and maxillofacial surgery. en-copyright= kn-copyright= en-aut-name=RaeburnKazzara en-aut-sei=Raeburn en-aut-mei=Kazzara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KikutaShogo en-aut-sei=Kikuta en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=SamridRarinthorn en-aut-sei=Samrid en-aut-mei=Rarinthorn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LoukasMarios en-aut-sei=Loukas en-aut-mei=Marios kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TubbsR.

Here, we analyzed the gene-knockout effects of eight lytic transglycosylases (slt, mltA, mltB, mltC, mltD, mltE, mltF, mltG) on antibiotic sensitivity in Escherichia coli. Knockout of both slt and mltG increased sensitivity to β-lactam antibiotics and reduced sensitivity to vancomycin. The β-lactam antibiotic sensitivity and vancomycin resistance of the slt-knockout mutant were abolished by the introduction of the wild-type slt gene but remained unchanged by the introduction of the mutant slt gene encoding an amino acid substitution variant of the transglycosylase catalytic centre. The double-knockout strain for slt and mltB was more sensitive to ampicillin and more resistant to vancomycin than each single-knockout strain. The double-knockout strain for slt and mltG was more sensitive to ampicillin and more resistant to vancomycin than each single-knockout strain. These results suggest that loss of lytic transglycosylase activity causes β-lactam antibiotic sensitivity and vancomycin resistance in E. coli. en-copyright= kn-copyright= en-aut-name=KimuraTakahiko en-aut-sei=Kimura en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagawaRyosuke en-aut-sei=Nakagawa en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Laboratory of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Escherichia coli kn-keyword=Escherichia coli en-keyword=lytic transglycosylase kn-keyword=lytic transglycosylase en-keyword=seesaw effect kn-keyword=seesaw effect en-keyword=vancomycin kn-keyword=vancomycin en-keyword=β‐lactam antibiotics kn-keyword=β‐lactam antibiotics END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99858 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural basis for molecular assembly of fucoxanthin chlorophyll a/c-binding proteins in a diatom photosystem I supercomplex en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic organisms exhibit remarkable diversity in their light-harvesting complexes (LHCs). LHCs are associated with photosystem I (PSI), forming a PSI-LHCI supercomplex. The number of LHCI subunits, along with their protein sequences and pigment compositions, has been found to differ greatly among the PSI-LHCI structures. However, the mechanisms by which LHCIs recognize their specific binding sites within the PSI core remain unclear. In this study, we determined the cryo-electron microscopy structure of a PSI supercomplex incorporating fucoxanthin chlorophyll a/c-binding proteins (FCPs), designated as PSI-FCPI, isolated from the diatom Thalassiosira pseudonana CCMP1335. Structural analysis of PSI-FCPI revealed five FCPI subunits associated with a PSI monomer; these subunits were identified as RedCAP, Lhcr3, Lhcq10, Lhcf10, and Lhcq8. Through structural and sequence analyses, we identified specific protein–protein interactions at the interfaces between FCPI and PSI subunits, as well as among FCPI subunits themselves. Comparative structural analyses of PSI-FCPI supercomplexes, combined with phylogenetic analysis of FCPs from T. pseudonana and the diatom Chaetoceros gracilis, underscore the evolutionary conservation of protein motifs crucial for the selective binding of individual FCPI subunits. These findings provide significant insights into the molecular mechanisms underlying the assembly and selective binding of FCPIs in diatoms. en-copyright= kn-copyright= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=XingJian en-aut-sei=Xing en-aut-mei=Jian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumazawaMinoru en-aut-sei=Kumazawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaHaruya en-aut-sei=Ogawa en-aut-mei=Haruya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagaoRyo en-aut-sei=Nagao en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Faculty of Agriculture, Shizuoka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=18981 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of galectin-9 in the development of gestational diabetes mellitus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Galectin-9 (Gal-9) is highly expressed in trophoblasts in placenta. Interaction between Gal-9 and T-cell immunoglobulin and mucin-domain containing-3 (Tim-3) is important for the differentiation of tissue resident natural killer (trNK) cells in placenta and maintenance of normal pregnancy. Furthermore, the enhanced maternal systemic inflammation associated with increased proinflammatory cytokines in preeclampsia is mediated by enhanced interaction between Gal-9 and Tim-3. However, the role of Gal-9 in gestational diabetes (GDM) remains unexplored. Plasma Gal-9 levels were elevated at 3rd trimester in pregnant women with GDM and positively correlated with placenta and newborn weight. Lgals9 knockout pregnant mice fed with high fat diet (HFD KO) demonstrated maternal glucose intolerance and fetus macrosomia compared with controls (HFD WT). In HFD KO, increased proliferating cells, reduced apoptosis, and autophagy impairment were observed in junctional zones. The number of trNK cells and percentage of Tim-3 + trNK increased, while early apoptosis percentage in Tim-3 + trNK was reduced in placenta of HFD KO. The elevation of plasma Gal-9 may be a biomarker for prediction of maternal glucose intolerance and fetal macrosomia in pregnant women with GDM and Gal-9 functions as a compensation factor for GDM by inducing apoptosis in Tim-3 + trNK cells. en-copyright= kn-copyright= en-aut-name=AlbuayjanHaya Hamed Hassan en-aut-sei=Albuayjan en-aut-mei=Haya Hamed Hassan kn-aut-name= kn-aut-sei= kn-aut-mei=
