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

Although surgical resection remains the standard treatment, its invasiveness has prompted interest in less invasive alternatives, particularly for small non-functional pNETs (NF-pNETs) and insulinomas.
Objectives: To evaluate the clinical efficacy and safety of endoscopic ultrasound-guided ethanol injection (EUS-EI) and radiofrequency ablation (EUS-RFA) for pNETs.
Design: A systematic review and meta-analysis.
Data sources and methods: A literature search of PubMed, MEDLINE, and Google Scholar was conducted (April 2005–April 2025). Studies were eligible if they reported clinical outcomes of EUS-EI or EUS-RFA in adult patients with insulinomas or NF-pNETs. The primary endpoints were clinical success (short-term symptom resolution or radiological response) and adverse event (AE) rates. Data were pooled using a random-effects model.
Results: Twenty-six studies were included in the meta-analysis. For insulinomas, the pooled clinical success rate was 77% (95% confidence interval (CI), 59–88) for EUS-EI and 95% (95% CI, 89–97) for EUS-RFA. The pooled incidence of total AEs was 32% (95% CI, 17–51) for EUS-EI and 25% (95% CI, 15–39) for EUS-RFA. For NF-pNETs, the pooled clinical success rates were 76% (95% CI, 54–90) for EUS-EI and 85% (95% CI, 74–92) for EUS-RFA, and the pooled incidence of total AEs was 27% (95% CI, 20–35) and 26% (95% CI, 17–38), respectively. The most common moderate or severe AEs were pancreatitis in 12 patients (7.6%) after EUS-EI, and pancreatic fluid collection in 4 patients (1.9%) and pancreatic duct stricture in 3 patients (1.4%) after EUS-RFA. One fatal case occurred in a 97-year-old patient following EUS-RFA.
Conclusion: Both EUS-EI and EUS-RFA are effective, relatively safe, and minimally invasive treatment options for pNETs. However, severe AE can occur, and careful patient selection and treatment indication are essential.

Lengths of expanded repeats inversely correlated with age at onset of epilepsy. Gain-of-toxic function mechanisms are suggested by the presence of UUUCA-repeat-containing RNA foci. From families with BAFME who did not have repeat expansions in SAMD12, we identified expanded TTTCA and TTTTA repeats in TNRC6A and RAPGEF2. These findings indicated a strong correlation between the repeat motif and the phenotype, leading to the identification of other types of BAFME. We then conducted genetic analysis of neuronal intranuclear inclusion disease (NIID), oculopharyngeal myopathy with leukoencephalopathy (OPML), and oculopharyngodistal myopathy (OPDM). From the observation that NIID, OPML, and OPDM, in addition to fragile X-associated tremor/ataxia syndrome, have shared clinical features, a direct search for CGG repeat expansions successfully led to the identification of the causative genes. Here, I review recent studies on repeat expansions. 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, Okayama UniversityGraduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=413 end-page=419 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=COVID-19 and the Risks of Migraine and Headache: A Mendelian Randomization Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Several observational studies suggested that migraine headache attacks were associated with coronavirus disease 2019 (COVID-19). We investigated genetic causal links between COVID-19 phenotypes and the development of headache and migraine, including migraine with aura (MA) and migraine without aura (MO). We conducted a two-sample Mendelian randomization (MR) analysis to estimate the genetic association in European populations. The inverse-variance weighted (IVW) method was used as the main approach in the MR analyses, together with weighted median and MR-Egger methods. We also performed a series of sensitivity tests to assess the robustness of the MR results. The MR results demonstrated that COVID-19 severity, hospitalization, and susceptibility had no causal effect on the risks of headache, migraine, MA, or MO. No horizontal pleiotropy was detected, and the results were robust as supported by the sensitivity analysis findings. Our analyses identified no casual effect of COVID-19 severity, hospitalization, or susceptibility on the risks of headache or migraine in European populations. en-copyright= kn-copyright= en-aut-name=JiangZhiyun en-aut-sei=Jiang en-aut-mei=Zhiyun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=XiYing en-aut-sei=Xi en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Clinical Laboratory, The First Affiliated Hospital of Zhengzhou University kn-affil= affil-num=2 en-affil=Department of Clinical Laboratory, The First Affiliated Hospital of Zhengzhou University kn-affil= en-keyword=headache kn-keyword=headache en-keyword=migraine kn-keyword=migraine en-keyword=Mendelian randomization kn-keyword=Mendelian randomization en-keyword=COVID-19 kn-keyword=COVID-19 END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=6 article-no= start-page=dsaf030 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=MedakaBase as a unified genomic resource platform for medaka fish biology en-subtitle= kn-subtitle= en-abstract= kn-abstract=Medaka, a group of small, mostly freshwater fishes in the teleost order Beloniformes, includes the rice fish Oryzias latipes, a useful model organism studied in diverse biological fields. Chromosome-scale genome sequences of the Hd-rR strain of this species were obtained in 2007, and its improved version has facilitated various genome-wide studies. However, despite its widespread utility, omics data for O. latipes are dispersed across various public databases and lack a unified platform. To address this, the medaka section of the National Bioresource Project (NBRP) of Japan established a genome informatics team in 2022 tasked with providing various in silico solutions for bench biologists. This initiative led to the launch of MedakaBase (https://medakabase.nbrp.jp), a web server that enables gene-oriented analysis including exhaustive sequence similarity searches. MedakaBase also provides on-demand browsing of diverse genome-wide datasets, including tissue-specific transcriptomes and intraspecific genomic variations, integrated with gene models from different sources. Additionally, the platform offers gene models optimized for single-cell transcriptome analysis, which often requires coverage of the 3′ untranslated region (UTR) of transcripts. Currently, MedakaBase provides genome-wide data for seven Oryzias species, including original data for O. mekongensis and O. luzonensis produced by the NBRP team. This article outlines technical details behind the data provided by MedakaBase. en-copyright= kn-copyright= en-aut-name=MorikamiKenji en-aut-sei=Morikami en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanizawaYasuhiro en-aut-sei=Tanizawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaguraMasaru en-aut-sei=Yagura en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoMika en-aut-sei=Sakamoto en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawamotoShoko en-aut-sei=Kawamoto en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraYasukazu en-aut-sei=Nakamura en-aut-mei=Yasukazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamaguchiKatsushi en-aut-sei=Yamaguchi en-aut-mei=Katsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShigenobuShuji en-aut-sei=Shigenobu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NaruseKiyoshi en-aut-sei=Naruse en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KurakuShigehiro en-aut-sei=Kuraku en-aut-mei=Shigehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Molecular Life History Laboratory, Department of Genomics and Evolutionary Biology, National Institute of Genetics, Research Organization of Information and Systems kn-affil= affil-num=2 en-affil=Genome Informatics Laboratory, National Institute of Genetics, Research Organization of Information and Systems kn-affil= affil-num=3 en-affil=Molecular Life History Laboratory, Department of Genomics and Evolutionary Biology, National Institute of Genetics, Research Organization of Information and Systems kn-affil= affil-num=4 en-affil=Genome Informatics Laboratory, National Institute of Genetics, Research Organization of Information and Systems kn-affil= affil-num=5 en-affil=Department of Genetics, Sokendai (Graduate University for Advanced Studies) kn-affil= affil-num=6 en-affil=Genome Informatics Laboratory, National Institute of Genetics, Research Organization of Information and Systems kn-affil= affil-num=7 en-affil=Trans-Omics Facility, National Institute for Basic Biology kn-affil= affil-num=8 en-affil=Trans-Omics Facility, National Institute for Basic Biology kn-affil= affil-num=9 en-affil=Laboratory of Bioresources, National Institute for Basic Biology, National Institutes of Natural Sciences kn-affil= affil-num=10 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=11 en-affil=Molecular Life History Laboratory, Department of Genomics and Evolutionary Biology, National Institute of Genetics, Research Organization of Information and Systems kn-affil= en-keyword=medaka kn-keyword=medaka en-keyword=comparative genomics kn-keyword=comparative genomics en-keyword=genome browser kn-keyword=genome browser en-keyword=MedakaBase kn-keyword=MedakaBase en-keyword=Beloniformes kn-keyword=Beloniformes 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=20250111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Linear Search Algorithm for Resource Allocation in Frequency Domain Non-Orthogonal Multiple Access en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes a linear search algorithm for resource allocation in frequency domain non-orthogonal multiple access based on the low-density signature (LDS). Although the proposed linear search enables the non-orthogonal multiple access to achieve superior transmission performance, the proposed linear search makes the resource allocation implemented with lower and fixed computational complexity. The performance of the non-orthogonal access based on the proposed linear search is evaluated by computer simulation. The proposed linear search algorithm makes the non-orthogonal multiple access achieve a gain of about 6 dB at the BER of 10–5 when the overloading ratio is set to 2. The complexity of the non-orthogonal access based on the proposed linear search algorithm is approximately half as much as that of the conventional low complexity resource allocation when the overloading ratio is 2, if the complexity is evaluated in terms of the number of additions. en-copyright= kn-copyright= en-aut-name=DennoSatoshi en-aut-sei=Denno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhbaYuto en-aut-sei=Ohba en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HouYafei en-aut-sei=Hou en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=non-orthogonal multiple access kn-keyword=non-orthogonal multiple access en-keyword=frequency domain kn-keyword=frequency domain en-keyword=linear search kn-keyword=linear search en-keyword=low complexity kn-keyword=low complexity END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=11 article-no= start-page=e13960 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Missing the Target: A Scoping Review of the Use of Percent Weight Loss for Obesity Management en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: To co-create comprehensive targets for obesity management, we need to understand the genesis and current use of percent weight loss targets in research. The goals of our scoping review are to (1) synthesize the literature on percent weight loss targets for adults with obesity and (2) discuss the percent weight loss targets in context with their health benefits.
Methods: We searched Cochrane, MEDLINE, and EMBASE for English language, pharmaceutical, and/or behavioral intervention studies in adults with obesity where the explicit aim of the study was weight reduction defined as a percent of body weight. Reviewers screened citations and extracted data including study characteristics.
Results: From 16,164 abstracts, we included 30 citations which were mostly randomized controlled trials (RCTs) (n = 17) or quasi-experimental studies (n = 12) published between 1992 and 2024. Most of the studies had target weight loss goals between 3% and 10% of body weight (n = 28), while n = 2 had body weight loss goals of 15% or 30%. The proportion of participants who met the percent weight loss target ranged from 5.9% (nutrition only study) to 85% (pharmaceutical study). The studies reported different reasons for targeting a percentage of weight loss such as disease-specific outcomes, reduced risk of disease, or patient-reported outcomes.
Conclusion: Percent weight loss targets were based on similar research and were often not feasible nor sustainable for most participants.

It also characterizes the convergence speed of some dynamic processes over networks. In this paper, taking into account that homogeneous networks are modeled as regular graphs, we tackle the following problem: given a pair (𝑛, 𝑘) of positive integers such that 𝑘 is less than 𝑛 and kn is an even number, find a 𝑘-regular graph with 𝑛 vertices that have the maximum algebraic connectivity. We first consider some special cases and derive solutions through theoretical analysis. We next present depth-first search algorithms for solving the problem, which reduce the search space by making use of some known properties of the regular graph and the algebraic connectivity.We also show the results of execution of the proposed algorithms for the values of 𝑛 up to 12. en-copyright= kn-copyright= en-aut-name=KurahashiMasashi en-aut-sei=Kurahashi en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SalaaniNajd en-aut-sei=Salaani en-aut-mei=Najd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MigitaTsuyoshi en-aut-sei=Migita en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiNorikazu en-aut-sei=Takahashi en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Polytech Sorbonne, Sorbonne 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=algebraic connectivity kn-keyword=algebraic connectivity en-keyword=depth-first search kn-keyword=depth-first search en-keyword=optimization kn-keyword=optimization en-keyword=pruning kn-keyword=pruning en-keyword=regular graph kn-keyword=regular graph END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue=5 article-no= start-page=291 end-page=301 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Systematic Review and Meta-Analysis of Penis Length and Circumference According to WHO Regions: Who has the Biggest One? en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to perform a systematic review and meta-analysis of stretched, erect, and flaccid penis length as well as circumference according to geographic WHO regions. PubMed, Embase, Scopus, and Cochrane Library were searched for articles published until February 2024. Studies in which a healthcare professional evaluated the penis size were considered eligible. After assessing the risk of bias, a systematic review and meta-analyses were performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement, and the outcomes were grouped based on the WHO regions. A total of 33 studies comprising 36 883 patients were included. The risk of bias in the included studies was moderate/low. A comprehensive systematic review was done and meta-analyses performed for flaccid length [n = 28 201, mean (SE) 9.22 (0.24) cm], stretched length [n = 20 814, mean (SE) 12.84 (0.32) cm], erect length [n = 5669, mean (SE) 13.84 (0.94) cm], flaccid circumference [n = 30 117, mean (SE) 9.10 (0.12) cm], and erect circumference [n = 5168, mean (SE) 11.91 (0.18) cm]. The mean length of the stretched penis was largest in Americans [14.47 (0.90) cm]. The mean length of the flaccid penis was the largest in the Americas [10.98 (0.064) cm]. The mean flaccid penile circumference was largest in Americans [n = 29 714, mean (SE) 10.00 (0.04) cm]. Penis sizes vary across WHO regions, suggesting the need to adjust standards according to geography to better understand councilmen and their partners. These data provide a framework for discussing body image expectations and therapeutic strategies in this sensitive and emotional subject matter. en-copyright= kn-copyright= en-aut-name=MostafaeiHadi en-aut-sei=Mostafaei en-aut-mei=Hadi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriKeiichiro en-aut-sei=Mori en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=QuhalFahad en-aut-sei=Quhal en-aut-mei=Fahad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PradereBenjamin en-aut-sei=Pradere en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YanagisawaTakafumi en-aut-sei=Yanagisawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LaukhtinaEkaterina en-aut-sei=Laukhtina en-aut-mei=Ekaterina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KönigFrederik en-aut-sei=König en-aut-mei=Frederik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MotlaghReza Sari en-aut-sei=Motlagh en-aut-mei=Reza Sari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=RajwaPawel en-aut-sei=Rajwa en-aut-mei=Pawel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Salehi-PourmehrHanieh en-aut-sei=Salehi-Pourmehr en-aut-mei=Hanieh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HajebrahimiSakineh en-aut-sei=Hajebrahimi en-aut-mei=Sakineh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ShariatShahrokh F. en-aut-sei=Shariat en-aut-mei=Shahrokh F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=2 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=3 en-affil=Department of Urology Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=5 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=6 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=7 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=8 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=9 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=10 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=11 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=12 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=13 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= en-keyword=Penis kn-keyword=Penis en-keyword=length kn-keyword=length en-keyword=circumference kn-keyword=circumference en-keyword=world health organization kn-keyword=world health organization END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=2 article-no= start-page=1 end-page=13 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=Advancements in systemic therapy for muscle-invasive bladder cancer: A systematic review from the beginning to the latest updates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Context: Several phase III randomized controlled trials (RCTs) have shown the importance of perioperative systemic therapy, especially for the efficacy of immune checkpoint inhibitors (ICIs) in both neoadjuvant and adjuvant settings for muscle-invasive bladder cancer (MIBC).
Objective: To synthesize the growing evidence on the efficacy and safety of systemic therapies for MIBC utilizing the data from RCTs.
Evidence acquisition: Three databases and ClinicalTrials.gov were searched in October 2024 for eligible RCTs evaluating oncologic outcomes in MIBC patients treated with systemic therapy. We evaluated pathological complete response (pCR), disease-free survival (DFS), progression-free survival (PFS), event-free survival (EFS), overall survival (OS), and adverse events (AEs).
Evidence synthesis: Thirty-three RCTs (including 14 ongoing trials) were included in this systematic review. Neoadjuvant chemotherapy improved OS compared to radical cystectomy alone. Particularly, the VESPER trial demonstrated that dd-MVAC provided oncological benefits over GC alone in terms of pCR rates, OS (HR: 0.71), and PFS (HR: 0.70). Recently, the NIAGARA trial showed that perioperative durvalumab plus GC outperformed GC alone in terms of pCR rates, OS (HR: 0.75), and EFS (HR: 0.68). Despite the lack of data on overall AE rates in the VESPER trial, differential safety profiles in hematologic toxicity were reported between dd-MVAC and durvalumab plus GC regimens. In the adjuvant setting, no study provided the OS benefit from adjuvant chemotherapy. However, only adjuvant nivolumab had significant DFS and OS benefits compared to placebo.
Conclusions: Neoadjuvant chemotherapy remains the current standard of care for MIBC. Durvalumab shed light on the promising impact of ICIs added to neoadjuvant chemotherapy. Nivolumab is the only ICI recommended as adjuvant therapy in patients who harbored adverse pathologic outcomes. Ongoing trials will provide further information on the impact of combination therapy, including chemotherapy, ICIs, and enfortumab vedotin, in both neoadjuvant and adjuvant settings. en-copyright= kn-copyright= en-aut-name=YanagisawaTakafumi en-aut-sei=Yanagisawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TeohJeremy Yuen-Chun en-aut-sei=Teoh en-aut-mei=Jeremy Yuen-Chun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriKeiichiro en-aut-sei=Mori en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawadaTatsushi en-aut-sei=Kawada en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=RajwaPaweł en-aut-sei=Rajwa en-aut-mei=Paweł kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=QuhalFahad en-aut-sei=Quhal en-aut-mei=Fahad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=PradereBenjamin en-aut-sei=Pradere en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MoschiniMarco en-aut-sei=Moschini en-aut-mei=Marco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShariatShahrokh F. en-aut-sei=Shariat en-aut-mei=Shahrokh F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MikiJun en-aut-sei=Miki en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KimuraTakahiro en-aut-sei=Kimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=2 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=3 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=4 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=8 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=9 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=10 en-affil=Department of Urology, San Raffaele Hospital and Scientific Institute kn-affil= affil-num=11 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=12 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=13 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= en-keyword=immune checkpoint inhibitors kn-keyword=immune checkpoint inhibitors en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=urothelial carcinoma kn-keyword=urothelial carcinoma en-keyword=muscle-invasive kn-keyword=muscle-invasive en-keyword=neoadjuvant kn-keyword=neoadjuvant en-keyword=adjuvant kn-keyword=adjuvant END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=195 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Improved Reference Paper Collection System Using Web Scraping with Three Enhancements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, accessibility to academic papers has been significantly improved with electric publications on the internet, where open access has become common. At the same time, it has increased workloads in literature surveys for researchers who usually manually download PDF files and check their contents. To solve this drawback, we have proposed a reference paper collection system using a web scraping technology and natural language models. However, our previous system often finds a limited number of relevant reference papers after taking long time, since it relies on one paper search website and runs on a single thread at a multi-core CPU. In this paper, we present an improved reference paper collection system with three enhancements to solve them: (1) integrating the APIs from multiple paper search web sites, namely, the bulk search endpoint in the Semantic Scholar API, the article search endpoint in the DOAJ API, and the search and fetch endpoint in the PubMed API to retrieve article metadata, (2) running the program on multiple threads for multi-core CPU, and (3) implementing Dynamic URL Redirection, Regex-based URL Parsing, and HTML Scraping with URL Extraction for fast checking of PDF file accessibility, along with sentence embedding to assess relevance based on semantic similarity. For evaluations, we compare the number of obtained reference papers and the response time between the proposal, our previous work, and common literature search tools in five reference paper queries. The results show that the proposal increases the number of relevant reference papers by 64.38% and reduces the time by 59.78% on average compared to our previous work, while outperforming common literature search tools in reference papers. Thus, the effectiveness of the proposed system has been demonstrated in our experiments. en-copyright= kn-copyright= en-aut-name=FahrudinTresna Maulana en-aut-sei=Fahrudin en-aut-mei=Tresna Maulana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaingInzali en-aut-sei=Naing en-aut-mei=Inzali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuhaiminAmri en-aut-sei=Muhaimin en-aut-mei=Amri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PrasetyaDwi Arman en-aut-sei=Prasetya en-aut-mei=Dwi Arman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Data Science, Universitas Pembangunan Nasional Veteran Jawa Timur kn-affil= affil-num=7 en-affil=Department of Data Science, Universitas Pembangunan Nasional Veteran Jawa Timur kn-affil= en-keyword=reference paper collection kn-keyword=reference paper collection en-keyword=multiple API integration kn-keyword=multiple API integration en-keyword=PDF accessibility kn-keyword=PDF accessibility en-keyword=open access kn-keyword=open access en-keyword=multiple threads kn-keyword=multiple threads END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue= article-no= start-page=1646835 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Muscle morphological adaptations to resistance training and sports participation in children and adolescents: a scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: This scoping review aimed to systematically map the existing literature on the effects of resistance training (RT) and sports participation on muscle morphology in children and adolescents.
Methods: Herein, a literature search was conducted using three electronic databases: PubMed, Scopus, and Web of Science. The inclusion criteria were as follows: articles that were written in English, which used chronic RT or a combination of RT with other training methods, or investigated the effects of sports participation, and reported muscle morphology as an outcome.
Results: This scoping review included 29 studies: 17 cross-sectional studies, 3 prospective observational studies, and 9 interventional studies. The following distribution was obtained after categorizing the included studies according to participant age: aged 6–11 years, 12 articles; aged 12–14 years, 10 articles; and aged 15–17 years, 10 articles. The designs of interventional studies included eight quasi-experimental parallel-group trials and a quasi-experimental crossover trial. However, none of the included interventional studies followed the CONSORT guidelines for conducting randomized controlled trials. Across the included studies, 14 different sports were analyzed for their effects on muscle morphology. Four studies combined players from various sports. In the included studies, 47 different muscles or muscle groups were examined. Our results identified unexplored muscles because our included studies did not examine the volume of lower leg muscles.
Conclusion: Future research directions in this field, including experimental design and targeted muscles, are warranted. en-copyright= kn-copyright= en-aut-name=EnomotoShota en-aut-sei=Enomoto en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TottoriNobuaki en-aut-sei=Tottori en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Education, Hyogo University of Teacher Education kn-affil= en-keyword=athlete kn-keyword=athlete en-keyword=cross-sectional area kn-keyword=cross-sectional area en-keyword=muscle thickness kn-keyword=muscle thickness en-keyword=muscle volume kn-keyword=muscle volume en-keyword=muscle-strengthening activity kn-keyword=muscle-strengthening activity en-keyword=youth kn-keyword=youth END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=189 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240827 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Post-spinel-type AB2O4 high-pressure phases in geochemistry and materials science en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-spinel-type AB2O4 compounds are stable at higher pressures than spinel phases.

Prospects are discussed for future searches for post-spinel-type phases by applying advanced large-volume high-pressure technology. en-copyright= kn-copyright= en-aut-name=AkaogiMasaki en-aut-sei=Akaogi en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauraKazunari en-aut-sei=Yamaura en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Gakushuin University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Research Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol=472 cd-vols= no-issue= article-no= start-page=123486 end-page= 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=Clinical, neuroimaging and genetic findings in the Japanese case series of CLCN2-related leukoencephalopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biallelic loss-of-function variants in CLCN2 lead to CLCN2-related leukoencephalopathy (CC2L), also called leukoencephalopathy with ataxia (LKPAT). CC2L is characterized clinically by a spectrum of clinical presentations including childhood- to adult-onset mild ataxia, spasticity, cognitive decline, and vision loss as well as typical MRI findings of symmetrical high signal intensities on the DWIs/T2WIs of the middle cerebellar peduncles (MCPs). We searched for pathogenic variants of CLCN2 in a case series of undiagnosed leukoencephalopathy accompanied by MCP signs, which led to the identification of four Japanese patients with CC2L. All the patients carried at least one allele of c.61dupC (p.Leu21Profs*27) in CLCN2, including compound heterozygosity with either the novel pathogenic variant c.983 + 2 T > A or the previously reported pathogenic variant c.1828C > T (p.Arg610*). Of note, all the four previously reported cases from Japan also harbored c.61dupC, and no reports of this variant have been documented from outside Japan. The allele frequency of c.61dupC in the Japanese population is 0.002152, raising the possibility of a relatively high prevalence of CC2L in Japan. Patients in this study developed symptoms after the age of 30, and demonstrated neurological signs including cerebellar ataxia, pyramidal signs, and mild cognitive impairment, consistent with previous reports. One male patient had two children, supporting preserved fertility, and another patient had calcifications in the cerebral and cerebellar surfaces. These findings provide valuable insights into the broader clinical and genetic spectra of CC2L in the Japanese population, and emphasize the importance of considering this disease in the differential diagnoses of leukoencephalopathy with MCP signs. en-copyright= kn-copyright= en-aut-name=OrimoKenta en-aut-sei=Orimo en-aut-mei=Kenta 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=MitsutakeAkihiko en-aut-sei=Mitsutake en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChoTakusei en-aut-sei=Cho en-aut-mei=Takusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaruseHiroya en-aut-sei=Naruse en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakiyamaYoshio en-aut-sei=Sakiyama en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SumiKensho en-aut-sei=Sumi en-aut-mei=Kensho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchioNaohiro en-aut-sei=Uchio en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatakeAkane en-aut-sei=Satake en-aut-mei=Akane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakiyamaYoshihisa en-aut-sei=Takiyama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsushitaTakuya en-aut-sei=Matsushita en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OmaeYosuke en-aut-sei=Omae en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KawaiYosuke en-aut-sei=Kawai en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TokunagaKatsushi en-aut-sei=Tokunaga en-aut-mei=Katsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 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=16 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=17 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=18 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, The University of Tokyo 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=Division of Neurology, First Department of Integrated Medicine, Saitama Medical Center, Jichi Medical University kn-affil= affil-num=7 en-affil=Department of Neurology, Mitsui Memorial Hospital kn-affil= affil-num=8 en-affil=Department of Neurology, Mitsui Memorial Hospital kn-affil= affil-num=9 en-affil=Department of Neurology, Fuefuki Central Hospital kn-affil= affil-num=10 en-affil=Department of Neurology, Fuefuki Central Hospital kn-affil= affil-num=11 en-affil=Department of Neurology, Kochi Medical School, Kochi University kn-affil= affil-num=12 en-affil=Genome Medical Science Project, National Center for Global Health and Medicine kn-affil= affil-num=13 en-affil=Genome Medical Science Project, National Center for Global Health and Medicine kn-affil= affil-num=14 en-affil=Genome Medical Science Project, National Center for Global Health and Medicine kn-affil= affil-num=15 en-affil=Department of Precision Medicine Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=16 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=17 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=18 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= en-keyword=Leukodystrophy kn-keyword=Leukodystrophy en-keyword=CC2L kn-keyword=CC2L en-keyword=CLCN2 kn-keyword=CLCN2 en-keyword=MCP sign kn-keyword=MCP sign END start-ver=1.4 cd-journal=joma no-vol=192 cd-vols= no-issue= article-no= start-page=155 end-page=162 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of exercise therapy on chemotherapy-induced peripheral neuropathy in patients with ovarian cancer: A scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background & aims. Exercise therapy is a potentially beneficial treatment option for chemotherapy-induced peripheral neuropathy (CIPN). However, there is a lack of consensus on the management of CIPN in patients with ovarian cancer. The purpose of this scoping review was to evaluate the evidence on the effectiveness of exercise therapy in patients with ovarian cancer and explore key physical fitness parameters.
Methods. A systematic electronic search was conducted using the MEDLINE, CINAHL, Web of Science, PEDro, and ClinicalTrials.gov databases. Two independent reviewers summarized the features and data from the literature regarding the effectiveness of exercise therapy for CIPN and the association between CIPN and physical fitness parameters.
Results. Ten articles involving 3402 participants were reviewed. The study design included one randomized controlled trial, one single-arm trial, one prospective cohort study, five retrospective cohort studies, and two cross-sectional studies. The mean patient age was >60 years in three studies and 50–60 years in six studies. The mean body mass index was >25.0 kg/m2 in six studies and not stated in four studies. In six references, patients received platinum and taxane-based chemotherapy. The effectiveness of an exercise therapy program for CIPN was reported in a randomized controlled trial. Two cross-sectional studies highlighted the association between daily physical inactivity and CIPN; two retrospective cohort studies showed an association between low skeletal muscle density and CIPN; one article demonstrated an association between physical dysfunction and CIPN.
Conclusion. This scoping review indicates that although evidence is lacking, exercise intervention programs for CIPN in patients with ovarian cancer have potential benefits, especially when focused on daily physical activity, skeletal muscle density, and physical function. en-copyright= kn-copyright= en-aut-name=KonumaMasanori en-aut-sei=Konuma en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitomaTomohiro en-aut-sei=Mitoma en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShirakawaShinsuke en-aut-sei=Shirakawa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagaoShoji en-aut-sei=Nagao en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= en-keyword=Ovarian cancer kn-keyword=Ovarian cancer en-keyword=Peripheral neuropathy kn-keyword=Peripheral neuropathy en-keyword=Sarcopenia kn-keyword=Sarcopenia en-keyword=Physical activity kn-keyword=Physical activity en-keyword=Exercise therapy kn-keyword=Exercise therapy END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=57 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Implant-supported fixed prostheses with cantilever: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This systematic review (SR) aimed to investigate whether the presence of a cantilever affects the results of implant treatment for partial edentulism, including an analysis of the anterior and posterior regions of the dental arches.
Methods An electronic search was performed, and original articles published between 1995 and November 2023 were included. The outcomes were the implant survival rate, patient satisfaction, occurrence of mechanical complications, and marginal bone loss around the implants. Two SR members independently examined the validity of the studies, extracted evidence from the included studies, and performed risk of bias assessment, comprehensive evidence evaluation, and meta-analysis.
Results Nine studies met our inclusion criteria. Implant survival rate tended to be lower in the cantilever group, and marginal bone loss tended to be higher in the cantilever group; however, there was no significant difference. There was no significant difference in patient satisfaction based on the presence or absence of a cantilever. Moreover, the incidence of mechanical complications was significantly higher in the cantilever group. According to the analysis of anterior and posterior regions, implant survival rate tended to be lower in the cantilever group of the posterior region, and marginal bone loss around the implants tended to be higher in the cantilever group of the anterior region.
Conclusion Implant-supported fixed prostheses with cantilevers did not negatively affect implant survival rate, marginal bone loss, or patient satisfaction. However, the incidence of mechanical complications significantly increased in the cantilever group. en-copyright= kn-copyright= en-aut-name=KondoYusuke en-aut-sei=Kondo en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiKiyoshi en-aut-sei=Sakai en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MinakuchiHajime en-aut-sei=Minakuchi en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HorimaiTakuya en-aut-sei=Horimai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JSOI Clinical Guideline Working Group collaborators en-aut-sei=JSOI Clinical Guideline Working Group collaborators en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Clinical Guideline Task-Force Members (2018-), Japanese Society of Oral Implantology (JSOI) kn-affil= affil-num=2 en-affil=Clinical Guideline Task-Force Members (2018-), Japanese Society of Oral Implantology (JSOI) kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Implantology, Okayama University Hospital kn-affil= affil-num=4 en-affil=The Library, School of Dentistry, Nihon University kn-affil= affil-num=5 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Faculty of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=Cantilever kn-keyword=Cantilever en-keyword=Fixed prostheses kn-keyword=Fixed prostheses en-keyword=Implants kn-keyword=Implants en-keyword=Partial edentulism kn-keyword=Partial edentulism en-keyword=Systematic review kn-keyword=Systematic review END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=4 article-no= start-page=715 end-page=721 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Telemedicine as an alternative to in-person care in the field of rheumatic diseases: A systematic scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The COVID-19 pandemic prompted the widespread adoption of telemedicine as an alternative to in-person care. This systematic scoping review evaluated the effectiveness, cost-efficiency, and challenges of telemedicine for patients with rheumatic diseases.
Methods: A comprehensive search of the MEDLINE database was conducted using specific terms related to rheumatoid or juvenile arthritis, and telemedicine. The literature search included studies published up to March, 2024. In this review, we only considered studies assessing telemedicine as an alternative to in-person care.
Results: The search, conducted on 15 March 2024, generated 258 references. Eight reports from three randomized controlled trials and three observational studies were included. Randomized controlled trials have shown that the outcomes of telemedicine intervention are comparable to those of in-person care in terms of disease activity, functional status, and quality of life, while enabling fewer outpatient visits and cost-effectiveness. However, the high dropout rates highlight the importance of patient preferences and comprehensive education. Observational studies revealed similar findings but were limited by a high confounding bias.
Conclusion: Telemedicine offers economic advantages and maintains clinical outcomes comparable to those of in-person care. Its success depends on structured patient education and alignment with patient preferences. Further research is required, particularly in the context of healthcare in Japan. en-copyright= kn-copyright= en-aut-name=SadaKen-ei en-aut-sei=Sada en-aut-mei=Ken-ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwataShigeru en-aut-sei=Iwata en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueYuzaburo en-aut-sei=Inoue en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaEiichi en-aut-sei=Tanaka en-aut-mei=Eiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawahitoYutaka en-aut-sei=Kawahito en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeAsami en-aut-sei=Abe en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=MiyamaeTakako en-aut-sei=Miyamae en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Clinical Epidemiology, Kochi Medical School kn-affil= affil-num=2 en-affil=Department of Rheumatology and Clinical Immunology, Wakayama Medical University kn-affil= affil-num=3 en-affil=Department of General Medical Science, Graduate School of Medicine, Chiba University kn-affil= affil-num=4 en-affil=Department of Rheumatology, Tokyo Women’s Medical University School of Medicine kn-affil= affil-num=5 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Inflammation and Immunology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine kn-affil= affil-num=7 en-affil=Department of Rheumatology, Niigata Rheumatic Center kn-affil= affil-num=8 en-affil=Department of Immunology and Rheumatology, Division of Advanced Preventive Medical Sciences, Nagasaki University Graduate School of Biomedical Sciences kn-affil= affil-num=9 en-affil=Department of Pediatric Rheumatology, Institute of Rheumatology, Tokyo Women’s Medical University kn-affil= en-keyword=Digital health kn-keyword=Digital health en-keyword=telemedicine kn-keyword=telemedicine en-keyword=remote care kn-keyword=remote care en-keyword=rheumatic disease kn-keyword=rheumatic disease en-keyword=scoping review kn-keyword=scoping review END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=1444 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=A Canine c-kit Novel Mutation Isolated from a Gastrointestinal Stromal Tumor (GIST) Retains the Ability to Form Dimers but Lacks Autophosphorylation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that develop in the gastrointestinal tract; KIT mutations are present in both canine and human GISTs. In this study, genomic DNA was extracted from formalin-fixed paraffin-embedded (FFPE) sections of 55 canine GIST cases, and mutation searches were performed for exons 8, 9, and 11. The results revealed novel mutations, A434T and F436S, in exon 8. In contrast to the A434T mutation without functional changes, the F436S mutant retained its dimerization ability, but lost its phosphorylation function and attenuated downstream Akt signaling, which is reflected in wound healing and migration activities. A comparison of the subcellular localization of WT KIT and the F436S mutant revealed no differences. In silico simulations indicated that the F436S mutation alters the structure of the near-membrane region and that its effects may extend to the transmembrane and intracellular domains compared to the WT. F436S is a point mutation that affects the entire molecule because co-mutation with the F436S mutation and the known autophosphorylation mutation reduces the autophosphorylation abilities. en-copyright= kn-copyright= en-aut-name=ShimakawaKei en-aut-sei=Shimakawa en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DogeSo en-aut-sei=Doge en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MichishitaMasaki en-aut-sei=Michishita en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanabeEri en-aut-sei=Tanabe en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TajimaTsuyoshi en-aut-sei=Tajima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiMasato en-aut-sei=Kobayashi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BonkobaraMakoto en-aut-sei=Bonkobara en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OchiaiKazuhiko en-aut-sei=Ochiai en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaYoshikazu en-aut-sei=Tanaka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=2 en-affil=Laboratory of Veterinary Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=3 en-affil=Laboratory of Veterinary Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=4 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=5 en-affil=Laboratory of Veterinary Pharmacology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=6 en-affil=Laboratory of Veterinary Reproduction, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=7 en-affil=Laboratory of Veterinary Clinical Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=8 en-affil=Laboratory of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=10 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= en-keyword=autophosphorylation kn-keyword=autophosphorylation en-keyword=canine kn-keyword=canine en-keyword=c-kit kn-keyword=c-kit en-keyword=GIST kn-keyword=GIST en-keyword=KIT kn-keyword=KIT en-keyword=loss-of-function mutation kn-keyword=loss-of-function mutation END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=7 article-no= start-page=001430 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic features of three major diarrhoeagenic Escherichia coli pathotypes in India en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Diarrhoea remains a major threat to children in developing nations, with diarrhoeagenic Escherichia coli (DEC) being the primary causative agent. Characterizing prevalent DEC strains is crucial, yet comprehensive genomic analyses of major DEC strains, including enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC) and enterotoxigenic E. coli (ETEC), are lacking in India.
Methods. We sequenced 24 EAEC and 23 EPEC strains from Indian patients with diarrhoea and conducted an extensive database search for DEC human isolates from India. Detailed phylogenetic analyses, virulence gene subtyping and examinations of accessory virulence and antimicrobial resistance (AMR) genes were performed.
Results. The analysed DEC strains included 32 EAEC, 25 EPEC, 32 ETEC and 1 each of the EPEC/ETEC-hybrid and ETEC/EAEC-hybrid pathotypes. These strains were predominantly classified into phylogroups A (35.2%) and B1 (41.8%) and dispersed within these phylogroups without pathotype-specific clustering. One ETEC strain was classified into cryptic clade 1. Subtypes of hallmark virulence genes varied substantially amongst strains in each pathotype, and 31 accessory virulence genes were detected either specifically within certain pathotypes or across multiple pathotypes at varying frequencies, indicating diversification of the virulence gene repertoire within each pathotype. Acquired AMR genes were found in 73.6% of the strains, with frequent identification of AMR genes for aminoglycosides (40.0%), β-lactams (64.8%), sulphonamides (49.5%) and trimethoprim (42.9%). Known quinolone-resistant mutations were found in 74.7% of the strains, whereas AMR genes for macrolide (30.8%), phenicol (11.0%) and tetracycline (27.4%) were less frequent.
Conclusions. The diverse virulence potential and trends in AMR gene prevalence amongst major DEC strains in India are highlighted in this study. Continuous monitoring of DEC strain characteristics is essential for the effective control and treatment of DEC infections in India. en-copyright= kn-copyright= en-aut-name=HoshikoYuki en-aut-sei=Hoshiko en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GhoshDebjani en-aut-sei=Ghosh en-aut-mei=Debjani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaganoDebora Satie en-aut-sei=Nagano en-aut-mei=Debora Satie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkunoMiki en-aut-sei=Okuno en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamamotoTakeshi en-aut-sei=Yamamoto en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OguraYoshitoshi en-aut-sei=Ogura en-aut-mei=Yoshitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=​Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine kn-affil= affil-num=2 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=3 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=4 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=5 en-affil=​Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine kn-affil= affil-num=6 en-affil=Collaborative Research Centre of Okayama University for Infectious Diseases, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=​Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine kn-affil= affil-num=9 en-affil=​Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine kn-affil= affil-num=10 en-affil=​Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=11 en-affil=​Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=12 en-affil=​Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine kn-affil= en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=diarrhoeagenic Escherichia coli kn-keyword=diarrhoeagenic Escherichia coli en-keyword=genome kn-keyword=genome en-keyword=India kn-keyword=India en-keyword=virulence gene kn-keyword=virulence gene END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=11 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250627 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between media literacy and searching skills on report assignments in nursing students in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: This study evaluates the relationship between information access and media literacy attitudes. We also assessed the impact of “Medical Literature Reading” on media literacy among Japanese university students. Methods: A cross-sectional study was conducted from April 2–16 and from August 2–16, 2024. A self-reporting questionnaire, including the school year, was used to determine if participants had taken the “Medical Literature Reading” course and to identify the sources often used for reporting assignments and media literacy. Results: This study included 195 subjects. The differences in media literacy scores between school years were analyzed. The total scores of fourth-year students were significantly higher than those of first-year on the media literacy scale (p = 0.014). The differences in media literacy scores among students enrolled in “Medical Literature Reading” were analyzed. The scores on the media literacy scale (p = 0.006) were significantly higher in participants than in non-participants. The relationships among the three groups by sources used for report assignments, school years (χ2(6) = 42.101, p < 0.0001), and history of taking “Medical Literature Reading” (χ2(2) = 7.048, p = 0.030) were also analyzed. Conclusions: Media literacy improved with schooling. Certain report assignments and subjects related to information literacy were found to have affected media literacy. Combining continuing experience and knowledge can lead to improvements in media literacy. en-copyright= kn-copyright= en-aut-name=NagaoYurii en-aut-sei=Nagao en-aut-mei=Yurii kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoWakana en-aut-sei=Yano en-aut-mei=Wakana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= affil-num=2 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= affil-num=3 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= en-keyword=Media literacy kn-keyword=Media literacy en-keyword=Media literacy education kn-keyword=Media literacy education en-keyword=Nursing department kn-keyword=Nursing department en-keyword=University students kn-keyword=University students 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. It has been shown that fake shopping websites use legitimate defaced landing websites as their leading paths. Therefore, if the detection of landing websites for fake shopping websites can be achieved, it can assist in addressing these websites and reduce the opportunities for users to be redirected to fake shopping websites. 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=14 cd-vols= no-issue=4 article-no= start-page=1055 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Natural Course and Long-Term Outcomes of Gastric Subepithelial Lesions: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Gastric subepithelial lesions (SELs) are often incidentally detected during endoscopic examinations, with most patients being asymptomatic and lesions measuring <20 mm. Despite their generally indolent nature, certain SELs, such as gastrointestinal stromal tumors, require resection. Current guidelines recommend periodic surveillance; however, the natural course and long-term outcomes of gastric SELs have not been sufficiently investigated. This systematic review aimed to synthesize evidence on the progression, growth rate, and risk factors associated with gastric SELs to inform clinical management strategies. Methods: A comprehensive search of PubMed was conducted for peer-reviewed studies published between January 2000 and November 2024. Eligible studies included original studies on the follow-up and progression of gastric SELs. Non-English articles, reviews, case reports, and unrelated topics were excluded. In total, 277 articles were screened, with 15 additional articles identified through manual screening. Ultimately, 41 articles were included in the analysis. The study protocol is registered in PROSPERO (CRD42024614865). Results: Large-scale studies reported low growth rates of 2.0-8.5% over 2.0-5.0 years, while smaller studies reported a broader range of growth rates of 5.4-28.4%. The factors contributing to these discrepancies include patient selection, follow-up duration, and growth criteria. Risk factors for lesion size increase include larger initial lesion size, irregular margins, heterogeneous echo patterns, and certain tumor locations. Conclusions: These findings underscore the need for individualized management strategies based on lesion size, imaging characteristics, and risk factors. The close monitoring of high-risk lesions is crucial for timely intervention. Standardized growth criteria and optimized follow-up protocols are essential for improving clinical decision making and patient outcomes. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=gastric lesions kn-keyword=gastric lesions en-keyword=gastrointestinal stromal tumor kn-keyword=gastrointestinal stromal tumor en-keyword=subepithelial lesion kn-keyword=subepithelial lesion en-keyword=submucosal tumor kn-keyword=submucosal tumor END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=10 article-no= start-page=1241 end-page=1252 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Validated international definition of the thrombocytopenia, anasarca, fever, reticulin fibrosis, renal insufficiency, and organomegaly clinical subtype (TAFRO) of idiopathic multicentric Castleman disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thrombocytopenia, anasarca, fever, reticulin fibrosis, renal insufficiency, and organomegaly (TAFRO) syndrome is a heterogeneous entity manifesting with a constellation of symptoms described above that can occur in the context of idiopathic multicentric Castleman disease (iMCD) as well as infectious diseases, malignancies, and rheumatologic disorders. So, iMCD-TAFRO is an aggressive subtype of iMCD with TAFRO syndrome and often hyper-vascularized lymph nodes. Since we proposed diagnostic criteria of iMCD-TAFRO in 2016, we have accumulated new insights on the disorder and additional cases have been reported worldwide. In this systematic review and cohort analysis, we established and validated a definition for iMCD-TAFRO. First, we searched PubMed and Japan Medical Abstracts Society databases using the keyword “TAFRO” to extract cases. Patients with possible systemic autoimmune diseases and hematologic malignancies were excluded. Our search identified 54 cases from 50 articles. We classified cases into three categories: (1) iMCD-TAFRO (TAFRO syndrome with lymph node histopathology consistent with iMCD), (2) possible iMCD-TAFRO (TAFRO syndrome with no lymph node biopsy performed and no other co-morbidities), and (3) TAFRO without iMCD or other co-morbidities (TAFRO syndrome with lymph node histopathology not consistent with iMCD or other comorbidities). Based on the findings, we propose an international definition requiring four clinical criteria (thrombocytopenia, anasarca, fever/hyperinflammatory status, organomegaly), renal dysfunction or characteristic bone marrow findings, and lymph node features consistent with iMCD. The definition was validated with an external cohort (the ACCELERATE Natural History Registry). The present international definition will facilitate a more precise and comprehensive approach to the diagnosis of iMCD-TAFRO. en-copyright= kn-copyright= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=PiersonSheila K. en-aut-sei=Pierson en-aut-mei=Sheila K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwakiNoriko en-aut-sei=Iwaki en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KawanoMitsuhiro en-aut-sei=Kawano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraNaoya en-aut-sei=Nakamura en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IzutsuKoji en-aut-sei=Izutsu en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakeuchiKengo en-aut-sei=Takeuchi en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= 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=10 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YoshizakiKazuyuki en-aut-sei=Yoshizaki en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 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=15 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=16 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=Center for Cytokine Storm Treatment & Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=3 en-affil=Center for Cytokine Storm Treatment & Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=4 en-affil=Hematology/Respiratory Medicine, Kanazawa University Graduate School of Medical Science kn-affil= affil-num=5 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Rheumatology, Kanazawa University Graduate School of Medical Science kn-affil= affil-num=7 en-affil=Department of Pathology, Tokai University School of Medicine kn-affil= affil-num=8 en-affil=Department of Hematology, National Cancer Center Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, The Cancer Institute Hospital of Japanese Foundation for Cancer Research kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Organic Fine Chemicals, Institute of Scientific and Industrial Research, Osaka University kn-affil= affil-num=14 en-affil=Department of Clinical Immunology, Hôpital Saint-Louis kn-affil= affil-num=15 en-affil=Myeloma Center, University of Arkansas for Medical Sciences kn-affil= affil-num=16 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=2 article-no= start-page=97 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Atypical lymphoplasmacytic and immunoblastic proliferation: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Atypical lymphoplasmacytic and immunoblastic proliferation (ALPIBP) was first reported in 1984 as characteristic histological findings in lymph nodes associated with autoimmune diseases, but it has not been clearly defined to date. To summarize the histological characteristics and clinical diagnoses associated with ALPIBP, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including “atypical lymphoplasmacytic and immunoblastic lymphadenopathy” from their inception to December 27, 2023. We also summarized the courses of three cases with a pathological diagnosis of ALPIBP. Nine articles with 52 cases were included. Among the total of 55 cases, including the three from our institution, the median age of the cases was 63.5 years with a female predominance (69.5%). Lymphadenopathy was generalized in 65.6% and regional in 34.4% of cases. RA (24.4%), SLE (24.4%), and autoimmune hemolytic anemia (20.0%), were common clinical diagnoses. A combination of cytotoxic chemotherapy was used in 15.6% of cases due to the suspicion of malignancy. Nodal T-follicular helper cell lymphoma, angioimmunoblastic type, methotrexate-associated lymphoproliferative disorders, and IgG4-related diseases were listed as important diseases that need to be pathologically differentiated from ALPIBP. This review summarizes the current understanding of the characteristics of ALPIBP. Given that underrecognition of ALPIBP could lead to overdiagnosis of hematological malignancy and unnecessary treatment, increased awareness of the condition in pathologists and clinicians is crucial. 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=TakahashiToshiaki en-aut-sei=Takahashi en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaokaKensuke en-aut-sei=Takaoka en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MacapagalSharina en-aut-sei=Macapagal en-aut-mei=Sharina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WannaphutChalothorn en-aut-sei=Wannaphut en-aut-mei=Chalothorn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=TodaHiroko en-aut-sei=Toda en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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 Medicine, John A.

It is an adaptor protein for the binding between Nedd4 of ubiquitin ligase (E3) and target substrate protein for ubiquitination. Northern blot analysis confirmed drastic increases in Ndfip1 mRNA in the striatum after METH injections, and in situ hybridization histochemistry showed that the mRNA expression was increased in the hippocampus and cerebellum at 2 h-2 days, in the cerebral cortex and striatum at 18 h-2 days after single METH administration. The knockdown of Ndfip1 expression with Ndfip1 siRNA significantly aggravated METH-induced neurotoxicity in the cultured monoaminergic neuronal cells. These results suggest that drastic increases in Ndfip1 mRNA is compensatory reaction to protect neurons against METH-induced neurotoxicity. en-copyright= kn-copyright= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CadetJean Lud en-aut-sei=Cadet en-aut-mei=Jean Lud kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Molecular Neuropsychiatry Section, Intramural Research Program, NIH/ NIDA kn-affil= en-keyword=Methamphetamine kn-keyword=Methamphetamine en-keyword=Neurotoxicity kn-keyword=Neurotoxicity en-keyword=Nedd4 kn-keyword=Nedd4 en-keyword=Ndfip1 kn-keyword=Ndfip1 en-keyword=Differential display kn-keyword=Differential display END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=2 article-no= start-page=102575 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical and microbiological characteristics of high-level daptomycin-resistant Corynebacterium species: A systematic scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Corynebacterium species potentially develop high-level daptomycin resistance (HLDR) shortly after daptomycin (DAP) administration. We aimed to investigate the clinical and microbiological characteristics of HLDR Corynebacterium infections.
Methods: We first presented a clinical case accompanied by the results of a comprehensive genetic analysis of the isolate, and then performed a systematic scoping review. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews, we searched for articles with related keywords, including “Corynebacterium”, “Daptomycin", and "Resistance”, in the MEDLINE and Web of Science databases from the database inception to October 25, 2024. Clinical case reports and research articles documenting the isolation of HLDR Corynebacterium species, defined by a minimum inhibitory concentration of DAP at ≥256 μg/mL, were deemed eligible for this review.
Results: Of 80 articles screened, seven case reports detailing eight cases of HLDR Corynebacterium infections, as well as five research articles, were included. C. striatum was the most common species (7/9 cases, 77.8 %), and prosthetic device-associated infections accounted for 66.7 % of the cases. Duration of DAP administration before the emergence of HLDR isolates ranged from 5 days to 3 months; three-quarters of the cases developed within 17 days. Three HLDR isolates were genetically confirmed to have an alteration in pgsA2. The majority of the patients were treated with either glycopeptides or linezolid, with favorable outcomes. In vitro experiments confirmed that C. striatum strains acquire the HLDR phenotype at higher rates (71 %–100 %) within 24 h of incubation, compared to other Corynebacterium strains.
Conclusion: DAP monotherapy, especially for prosthetic device-associated infections, can result in the development of HLDR Corynebacterium. Additional research is warranted to investigate the clinical implications of this potentially proliferating antimicrobial resistant pathogen. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=Corynebacterium kn-keyword=Corynebacterium en-keyword=Daptomycin kn-keyword=Daptomycin en-keyword=High-level daptomycin resistance kn-keyword=High-level daptomycin resistance en-keyword=pgsA2 kn-keyword=pgsA2 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=434 end-page=448 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230905 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Vibration Behavior in Low-Frequency Vibration Cutting on Surface Properties of Workpiece en-subtitle= kn-subtitle= en-abstract= kn-abstract=　The objective of this study was to determine the effect of vibration behavior on workpiece surface properties in low-frequency vibration cutting. The effects of the parameters that determine vibration behavior on surface roughness were quantitatively evaluated through a comparison with other cutting conditions. Furthermore, by clarifying how the surface properties of the workpiece, such as roughness, roundness, and cross-sectional curves, change depending on the vibration behavior, a search for optimal conditions for low-frequency vibration cutting was conducted. The best surface properties were obtained under the condition of spindle rotation per vibration E=4.5. By using a value close to the minimum possible spindle rotation R=0.5 when the workpiece is retracted, it is expected to be effective in suppressing the variation in surface roughness at each phase angle; this variation is characteristic of low-frequency vibration cutting. Workpieces machined under low-frequency vibration conditions such as (E=2.5, R=1.0) and (E=3.5, R=1.0) were found to form characteristic surface patterns on the workpiece surface owing to a phenomenon in which the depth of the cut to the workpiece changes. en-copyright= kn-copyright= en-aut-name=KodamaHiroyuki en-aut-sei=Kodama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsunoShota en-aut-sei=Matsuno en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibataNaoyuki en-aut-sei=Shibata en-aut-mei=Naoyuki 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=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= en-keyword=low-frequency vibration cutting kn-keyword=low-frequency vibration cutting en-keyword=vibration behavior kn-keyword=vibration behavior en-keyword=surface roughness kn-keyword=surface roughness en-keyword=cross-sectional curve kn-keyword=cross-sectional curve END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=10 article-no= start-page=251 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241014 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Searching Method for Three-Dimensional Puncture Route to Support Computed Tomography-Guided Percutaneous Puncture en-subtitle= kn-subtitle= en-abstract= kn-abstract=In CT-guided percutaneous punctures-an image-guided puncture method using CT images-physicians treat targets such as lung tumors, liver tumors, renal tumors, and intervertebral abscesses by inserting a puncture needle into the body from the exterior while viewing images. By recognizing two-dimensional CT images prior to a procedure, a physician determines the least invasive puncture route for the patient. Therefore, the candidate puncture route is limited to a two-dimensional region along the cross section of the human body. In this paper, we aim to construct a three-dimensional puncture space based on multiple two-dimensional CT images to search for a safer and shorter puncture route for a given patient. If all puncture routes starting from a target in the three-dimensional space were examined from all directions (the brute-force method), the processing time to derive the puncture route would be very long. We propose a more efficient method for three-dimensional puncture route selection in CT-guided percutaneous punctures. The proposed method extends the ray-tracing method, which quickly derives a line segment from a given start point to an end point on a two-dimensional plane, and applies it to three-dimensional space. During actual puncture route selection, a physician can use CT images to derive a three-dimensional puncture route that is safe for the patient and minimizes the puncture time. The main novelty is that we propose a method for deriving a three-dimensional puncture route within the allowed time in an actual puncture. The main goal is for physicians to select the puncture route they will use in the actual surgery from among the multiple three-dimensional puncture route candidates derived using the proposed method. The proposed method derives a three-dimensional puncture route within the allowed time in an actual puncture. Physicians can use the proposed method to derive a new puncture route, reducing the burden on patients and improving physician skills. In the evaluation results of a computer simulation, for a 3D CT image created by combining 170 two-dimensional CT images, the processing time for deriving the puncture route using the proposed method was approximately 59.4 s. The shortest length of the puncture route from the starting point to the target was between 20 mm and 22 mm. The search time for a three-dimensional human body consisting of 15 CT images was 4.77 s for the proposed method and 2599.0 s for a brute-force method. In a questionnaire, physicians who actually perform puncture treatments evaluated the candidate puncture routes derived by the proposed method. We confirmed that physicians could actually use these candidates as a puncture route. en-copyright= kn-copyright= en-aut-name=GotohYusuke en-aut-sei=Gotoh en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakedaAoi en-aut-sei=Takeda en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuiKoji en-aut-sei=Masui en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaiKoji en-aut-sei=Sakai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimotoManato en-aut-sei=Fujimoto en-aut-mei=Manato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=5 en-affil=Graduate School of Informatics, Osaka Metropolitan University kn-affil= en-keyword=CT-guided percutaneous puncture kn-keyword=CT-guided percutaneous puncture en-keyword=searching method kn-keyword=searching method en-keyword=three-dimensional puncture route kn-keyword=three-dimensional puncture route END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=387 end-page=399 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Radon Inhalation on Murine Brain Proteins: Investigation Using Proteomic and Multivariate Analyses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required. Although several studies have used proteomics to investigate the effects of radon inhalation on body proteins, none has focused on brain proteins. In this study, we evaluated the expression status of proteins in murine brains using proteomic and multivariate analyses to identify those whose expressions changed following two days of radon inhalation at a concentration of 1,500 Bq/m3. We found associations of radon inhalation with the expressions of seven proteins related to neurotransmission and heat shock. These proteins may be proposed as biomarkers indicative of radon inhalation. Although further studies are required to obtain the detailed biological significance of these protein alterations, this study contributes to the elucidation of the biological effects of radon inhalation as a low-dose radiation. en-copyright= kn-copyright= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=radon inhalation kn-keyword=radon inhalation en-keyword=proteomics kn-keyword=proteomics en-keyword=multivariate analysis kn-keyword=multivariate analysis en-keyword=brain kn-keyword=brain en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=e087657 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decline in and recovery of fertility rates after COVID-19-related state of emergency in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction The COVID-19 pandemic led to a decline in fertility rates worldwide. Although many regions have experienced a temporary drop in fertility rates with the spread of the infection, subsequent recovery has varied across countries. This study aimed to evaluate the impact of COVID-19 infection rates and regional sociodemographic factors on the recovery of fertility rates in Japan following the state of emergency.
Methods This study examined prefectural fertility data from before the COVID-19 pandemic to forecast fertility rates up to 2022 using a seasonal autoregressive integrated moving average model. A regression analysis was conducted on fertility rates during the first state of emergency and the subsequent recovery rate with respect to the number of new COVID-19 cases and sociodemographic factors specific to each prefecture.
Results During the first state of emergency, the monthly fertility rate decreased by an average of -13.8% (SD: 6.26, min: -28.78, max: 0.15) compared with the previous year. Over the following 22 months, the average fertility recovery rate was +2.31% (SD: 3.57; min: -8.55, max: 19.54). Multivariate analysis of the impact of the pandemic on fertility changes during the first emergency indicated a negative correlation between new COVID-19 cases per capita and the proportion of nuclear households. No significant correlation was found between fertility recovery rate and new COVID-19 cases or emergency duration. When classifying fertility rate fluctuation patterns before and after the emergency into four clusters, variations were noted in the proportion of the elderly population, marriage divorce rate and the number of internet searches related to pregnancy intentions across the clusters.
Conclusions No association was found between pregnancy intentions related to the spread of infection, such as the number of new cases and the fertility recovery rate following the first state of emergency. Differences in the patterns of decline and recovery during the pandemic were observed based on population composition and internet searches for infection and pregnancy across different prefectures. en-copyright= kn-copyright= en-aut-name=MitomaTomohiro en-aut-sei=Mitoma en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=e107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of psychological first aid in infectious disease pandemics: An overview of systematic reviews en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is insufficient research on the usefulness of psychological interventions, such as psychological first aid (PFA), during outbreaks. We searched for and critically appraised systematic reviews that examined the effectiveness of PFA during infectious disease outbreaks, such as the novel coronavirus disease (COVID-19). Systematic reviews that examined the efficacy of PFA in the severe acute respiratory syndrome, Middle East respiratory syndrome coronavirus, Ebola virus disease, and COVID-19 outbreaks were searched through PubMed on February 19, 2021. The three included systematic reviews were critically appraised and assessed using AMSTAR-2. One review's overall confidence in its findings was evaluated as “high,” which suggested that PFA training had a favorable effect on healthcare personnel. Furthermore, the review also demonstrated that PFA was commonly used during outbreaks and could be delivered through multiple methods, such as a phone or video call. Although it was anticipated that PFA would improve subjective well-being, reports showed no evidence of reduced depression or insomnia. Future studies should examine additional numbers of PFA recipients and conduct quasi-experimental studies to better understand the effectiveness of PFA. Evidence on its effectiveness in infectious disease outbreaks is still lacking, along with research and evaluation methods. Quasi-experimental studies, such as comparisons with other psychological interventions, are required to better understand the effectiveness of PFA. en-copyright= kn-copyright= en-aut-name=KodaMasahide en-aut-sei=Koda en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HorinouchiToru en-aut-sei=Horinouchi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OyaNozomu en-aut-sei=Oya en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiMorio en-aut-sei=Aki en-aut-mei=Morio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IrikiAkihisa en-aut-sei=Iriki en-aut-mei=Akihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaKazufumi en-aut-sei=Yoshida en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaYusuke en-aut-sei=Ogawa en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KugaHironori en-aut-sei=Kuga en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoTomohiro en-aut-sei=Nakao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Co‐Learning Community Healthcare Re‐Innovation Office, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Psychiatry, Hokkaido University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Psychiatry, Graduate School of Medical Science, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Psychiatry, Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Osaka Psychiatric Medical Center kn-affil= affil-num=6 en-affil=Department of Health Promotion and Human Behavior, Graduate School of Medicine/School of Public Health, Kyoto University kn-affil= affil-num=7 en-affil=Department of Healthcare Epidemiology, School of Public Health in the Graduate School of Medicine, Kyoto University kn-affil= affil-num=8 en-affil=National Center for Cognitive Behavior Therapy and Research, National Center of Neurology and Psychiatry kn-affil= affil-num=9 en-affil=Department of Neuropsychiatry, Graduate School of Medical Sciences, Kyushu University kn-affil= en-keyword=mental health kn-keyword=mental health en-keyword=pandemic kn-keyword=pandemic en-keyword=psychological first aid kn-keyword=psychological first aid en-keyword=psychosocial support kn-keyword=psychosocial support END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=11 article-no= start-page=971 end-page=979 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240905 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Job strain and adverse pregnancy outcomes: A scoping review and meta‐analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Previous studies have shown that job strain is associated with low birthweight (LBW), preterm birth (PTB), and small for gestational age (SGA). We conducted a scoping review and meta-analysis to assess the association between job strain and adverse pregnancy outcomes.
Methods: A literature search was performed on PubMed. We included English-language studies that examined the association between job strain (based on the Karasek demand-control model) and pregnancy outcomes. We excluded letters, posters, reviews, and qualitative studies. Random effects meta-analysis was performed. Heterogeneity was assessed using τ2 and I2 statistics. Potential bias was assessed using standard funnel plots. Asymmetry was evaluated by Egger's test. Leave-one-out analysis was performed for sensitivity analyses.
Results: Three eligible studies were found for LBW, seven for PTB, and four for SGA. The number of subjects ranged from 135 to 4889, and the prevalence of high job strain ranged from 6.64% to 33.9%. The pooled odds ratio and 95% confidence interval (CI) for LBW, PTB, and SGA were 1.23 (95% CI: 0.97, 1.56), 1.10 (95% CI: 1.00, 1.22), and 1.16 (95% CI: 0.97, 1.39) respectively, indicating modest associations. Heterogeneity for LBW and PTB may not be important but may be moderate for SGA. No publication bias was detected for LBW and PTB, but possible publication bias exists for SGA.
Conclusion: We found a modest association between job strain and PTB. Since job strain is only one of the many aspects of an unhealthy work environment, interventions that improve working conditions more broadly are needed. en-copyright= kn-copyright= en-aut-name=NakayamaKota en-aut-sei=Nakayama en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SlopenNatalie en-aut-sei=Slopen en-aut-mei=Natalie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawachiIchiro en-aut-sei=Kawachi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Social and Behavioral Sciences, Harvard T.H.

With the advancement of robotic manipulation, there are growing demands for the automation of packing tasks. However, the simultaneous optimization of packing and the robot's motion planning is challenging because these two decisions are interconnected, and no previous study has addressed this optimization problem. This paper presents a framework to simultaneously determine the robot's motion planning and packing decision to minimize the robot's processing time and the container's volume. This framework comprises three key components: solution encoding, surrogate modeling, and evolutionary computation. The sequence-triple representation encodes complex packing solutions by a sequence of integers. A surrogate model is trained to predict the processing time for a given packing solution to reduce the computational burden. Training data is generated by solving the motion planning problem for a set of packing solutions using the rapidly exploring random tree algorithm. The Non-Dominated Sorting Genetic Algorithm II searches for the Pareto solutions. Experimental evaluations are conducted using a 6-DOF robot manipulator. The experimental results suggest that implementing the surrogate model can reduce the computational time by 91.1%. The proposed surrogate-assisted optimization method can obtain significantly better solutions than the joint angular velocity-based estimation method. en-copyright= kn-copyright= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawabeTomoya en-aut-sei=Kawabe en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoShun en-aut-sei=Ito en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraTomofumi en-aut-sei=Fujiwara en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Packing problem kn-keyword=Packing problem en-keyword=sequence-triple kn-keyword=sequence-triple en-keyword=motion planning kn-keyword=motion planning en-keyword=surrogate model kn-keyword=surrogate model en-keyword=multi-objective optimization kn-keyword=multi-objective optimization END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=8 article-no= start-page=1005 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240807 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Enhanced Active Access-Point Configuration Algorithm Using the Throughput Request Satisfaction Method for an Energy-Efficient Wireless Local-Area Network en-subtitle= kn-subtitle= en-abstract= kn-abstract=Wireless Local-Area Networks (WLANs), as a popular internet access solution, are widely used in numerous places, including enterprises, campuses, and public venues. As the number of devices increases, large-scale deployments will cause the problem of dense wireless networks, including a lot of energy consumption. Thus, the optimization of energy-efficient wireless AP devices has become a focal point of attention. To reduce energy consumption, we have proposed the active access-point (AP) configuration algorithm for WLANs using APs with a dual interface. This uses the greedy algorithm combined with the local search optimization method to find the minimum number of activated APs while satisfying the minimum throughput constraint. However, the previous algorithm basically satisfies only the average throughput among the multiple hosts associated with one AP, wherein some hosts may not reach the required one. In this paper, to overcome this limitation, we propose an enhanced active AP configuration algorithm by incorporating the throughput request satisfaction method that controls the actual throughput at the target value (target throughput) for every host by applying traffic shaping. The target throughput is calculated from the single and concurrent communicating throughput of each host based on channel occupancy time. The minimum throughput constraint will be iteratively adjusted to obtain the required target throughput and achieve the fair throughput allocation. For evaluations, we conducted simulations using the WIMNET simulator and experiments using the testbed system with a Raspberry Pi 4B for APs in four topology cases with five APs and ten hosts. The results show that the proposed method always achieved the required minimum throughput in simulations as well as in experiments, while minimizing the number of active APs. Thus, the validity and effectiveness of our proposal were confirmed. en-copyright= kn-copyright= en-aut-name=WuBin en-aut-sei=Wu en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KongDezheng en-aut-sei=Kong en-aut-mei=Dezheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangXuan en-aut-sei=Wang en-aut-mei=Xuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SetoTaishiro en-aut-sei=Seto en-aut-mei=Taishiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FanYu-Cheng en-aut-sei=Fan en-aut-mei=Yu-Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Electronic Engineering, National Taipei University of Technology kn-affil= en-keyword=energy-efficient WLAN kn-keyword=energy-efficient WLAN en-keyword=IoT kn-keyword=IoT en-keyword=active AP configuration algorithm kn-keyword=active AP configuration algorithm en-keyword=throughput request satisfaction method kn-keyword=throughput request satisfaction method en-keyword=throughput control kn-keyword=throughput control en-keyword=traffic shaping kn-keyword=traffic shaping END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=14 article-no= start-page=4199 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New Delhi Metallo-Beta-Lactamase Inhibitors: A Systematic Scoping Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Among various carbapenemases, New Delhi metallo-beta-lactamases (NDMs) are recognized as the most powerful type capable of hydrolyzing all beta-lactam antibiotics, often conferring multi-drug resistance to the microorganism. The objective of this review is to synthesize current scientific data on NDM inhibitors to facilitate the development of future therapeutics for challenging-to-treat pathogens. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews, we conducted a MEDLINE search for articles with relevant keywords from the beginning of 2009 to December 2022. We employed various generic terms to encompass all the literature ever published on potential NDM inhibitors. Results: Out of the 1760 articles identified through the database search, 91 met the eligibility criteria and were included in our analysis. The fractional inhibitory concentration index was assessed using the checkerboard assay for 47 compounds in 37 articles, which included 8 compounds already approved by the Food and Drug Administration (FDA) of the United States. Time-killing curve assays (14 studies, 25%), kinetic assays (15 studies, 40.5%), molecular investigations (25 studies, 67.6%), in vivo studies (14 studies, 37.8%), and toxicity assays (13 studies, 35.1%) were also conducted to strengthen the laboratory-level evidence of the potential inhibitors. None of them appeared to have been applied to human infections. Conclusions: Ongoing research efforts have identified several potential NDM inhibitors; however, there are currently no clinically applicable drugs. To address this, we must foster interdisciplinary and multifaceted collaborations by broadening our own horizons. en-copyright= kn-copyright= en-aut-name=NaharLutfun en-aut-sei=Nahar en-aut-mei=Lutfun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsaduzzamanMd en-aut-sei=Asaduzzaman en-aut-mei=Md kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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 Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Bacteriology, 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= en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=carbapenemase-producing Enterobacterales kn-keyword=carbapenemase-producing Enterobacterales en-keyword=carbapenem-resistant Enterobacterales kn-keyword=carbapenem-resistant Enterobacterales en-keyword=metallo-beta-lactamase kn-keyword=metallo-beta-lactamase en-keyword=synergy kn-keyword=synergy en-keyword=combination kn-keyword=combination END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=14 article-no= start-page=2700 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Reference Paper Collection System Using Web Scraping en-subtitle= kn-subtitle= en-abstract= kn-abstract=Collecting reference papers from the Internet is one of the most important activities for progressing research and writing papers about their results. Unfortunately, the current process using Google Scholar may not be efficient, since a lot of paper files cannot be accessed directly by the user. Even if they are accessible, their effectiveness needs to be checked manually. In this paper, we propose a reference paper collection system using web scraping to automate paper collections from websites. This system can collect or monitor data from the Internet, which is considered as the environment, using Selenium, a popular web scraping software, as the sensor; this examines the similarity against the search target by comparing the keywords using the Bert model. The Bert model is a deep learning model for natural language processing (NLP) that can understand context by analyzing the relationships between words in a sentence bidirectionally. The Python Flask is adopted at the web application server, where Angular is used for data presentations. For the evaluation, we measured the performance, investigated the accuracy, and asked members of our laboratory to use the proposed method and provide their feedback. Their results confirm the method’s effectiveness. en-copyright= kn-copyright= en-aut-name=NaingInzali en-aut-sei=Naing en-aut-mei=Inzali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WaiKhaing Hsu en-aut-sei=Wai en-aut-mei=Khaing Hsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=web scraping kn-keyword=web scraping en-keyword=Google Scholar kn-keyword=Google Scholar en-keyword=data collection kn-keyword=data collection en-keyword=Bert kn-keyword=Bert en-keyword=Selenium kn-keyword=Selenium en-keyword=flask framework kn-keyword=flask framework en-keyword=Angular kn-keyword=Angular END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=13 article-no= start-page=6986 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240626 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genome-Wide Association Study with Three Control Cohorts of Japanese Patients with Esotropia and Exotropia of Comitant Strabismus and Idiopathic Superior Oblique Muscle Palsy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Esotropia and exotropia in the entity of comitant strabismus are multifactorial diseases with both genetic and environmental backgrounds. Idiopathic superior oblique muscle palsy, as the predominant entity of non-comitant (paralytic) strabismus, also has a genetic background, as evidenced by varying degrees of muscle hypoplasia. A genome-wide association study (GWAS) was conducted of 711 Japanese patients with esotropia (n= 253), exotropia (n = 356), and idiopathic superior oblique muscle palsy (n = 102). The genotypes of single nucleotide polymorphisms (SNPs) were determined by Infinium Asian Screening Array. Three control cohorts from the Japanese population were used: two cohorts from BioBank Japan (BBJ) and the Nagahama Cohort. BBJ (180K) was genotyped by a different array, Illumina Infinium OmniExpressExome or HumanOmniExpress, while BBJ (ASA) and the Nagahama Cohort were genotyped by the same Asian array. After quality control of SNPs and individuals, common SNPs between the case cohort and the control cohort were chosen in the condition of genotyping by different arrays, while all SNPs genotyped by the same array were used for SNP imputation. The SNPs imputed with R-square values ≥ 0.3 were used to compare the case cohort of each entity or the combined entity with the control cohort. In comparison with BBJ (180K), the esotropia group and the exotropia group showed CDCA7 and HLA-F, respectively, as candidate genes at a significant level of p < 5 × 10−8, while the idiopathic superior oblique muscle palsy group showed DAB1 as a candidate gene which is involved in neuronal migration. DAB1 was also detected as a candidate in comparison with BBJ (ASA) and the Nagahama Cohort at a weak level of significance of p < 1 × 10−6. In comparison with BBJ (180K), RARB (retinoic acid receptor-β) was detected as a candidate at a significant level of p < 5 × 10−8 in the combined group of esotropia, exotropia, and idiopathic superior oblique muscle palsy. In conclusion, a series of GWASs with three different control cohorts would be an effective method with which to search for candidate genes for multifactorial diseases such as strabismus. 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=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamataniYoichiro en-aut-sei=Kamatani en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawaguchiTakahisa en-aut-sei=Kawaguchi en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiIzumi en-aut-sei=Yamaguchi en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaFumihiko en-aut-sei=Matsuda en-aut-mei=Fumihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoAkira en-aut-sei=Saito en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakazonoKazuyuki en-aut-sei=Nakazono en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KamitsujiShigeo en-aut-sei=Kamitsuji en-aut-mei=Shigeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Computational Biology and Medical Sciences, Graduate School of Frontier Sciences, The University of Tokyo kn-affil= affil-num=4 en-affil=Center for Genomic Medicine, Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Center for Genomic Medicine, Graduate School of Medicine, Kyoto University kn-affil= affil-num=6 en-affil=Center for Genomic Medicine, Graduate School of Medicine, Kyoto University kn-affil= affil-num=7 en-affil=StaGen Co., Ltd. kn-affil= affil-num=8 en-affil=StaGen Co., Ltd. kn-affil= affil-num=9 en-affil=StaGen Co., Ltd. kn-affil= en-keyword=esotropia kn-keyword=esotropia en-keyword=exotropia kn-keyword=exotropia en-keyword=superior oblique muscle palsy kn-keyword=superior oblique muscle palsy en-keyword=genome-wide association study kn-keyword=genome-wide association study en-keyword=comitant strabismus kn-keyword=comitant strabismus en-keyword=non-comitant strabismus kn-keyword=non-comitant strabismus en-keyword=Japanese population kn-keyword=Japanese population en-keyword=BioBank Japan kn-keyword=BioBank Japan en-keyword=Nagahama Cohort kn-keyword=Nagahama Cohort en-keyword=Asian array kn-keyword=Asian array END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=7 article-no= start-page=847 end-page=859 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trends and issues in clinical research on satisfaction and quality of life after mastectomy and breast reconstruction: a 5-year scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast reconstruction (BR) aims to improve the satisfaction and quality of life (QOL) of breast cancer survivors. Clinical studies using patient-reported outcomes (PROs) can therefore provide relevant information to the patients and support decision-making. This scoping review was conducted to analyze recent trends in world regions, methods used, and factors investigated. The literature search was conducted in August 2022. Databases of PubMed, MEDLINE, and CINAHL were searched for relevant English-language studies published from 2017 to 2022. Studies involving women with breast cancer who underwent BR after mastectomy and investigated PROs after BR using BR-specific scales were included. Data on the country, publication year, study design, PRO measures (PROMs) used, time points of surveys, and research themes were collected. In total, 147 articles met the inclusion criteria. BREAST-Q was the most widely used, contributing to the increase in the number and diversification of studies in this area. Such research has been conducted mainly in North America and Europe and is still developing in Asia and other regions. The research themes involved a wide range of clinical and patient factors in addition to surgery, which could be influenced by research methods, time since surgery, and even cultural differences. Recent BR-specific PROMs have led to a worldwide development of research on factors that affect satisfaction and QOL after BR. PRO after BR may be influenced by local cultural and social features, and it would be necessary to accumulate data in each region to draw clinically useful conclusion. en-copyright= kn-copyright= en-aut-name=SaigaMiho en-aut-sei=Saiga en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagiriRyoko en-aut-sei=Nakagiri en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MukaiYuko en-aut-sei=Mukai en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Plastic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Plastic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Patient-reported outcomes kn-keyword=Patient-reported outcomes en-keyword=Breast reconstruction kn-keyword=Breast reconstruction en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Satisfaction kn-keyword=Satisfaction END start-ver=1.4 cd-journal=joma no-vol=141 cd-vols= no-issue= article-no= start-page=106955 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vibriosis in South Asia: A systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: South Asia remains home to foodborne diseases caused by the Vibrio species. We aimed to compile and update information on the epidemiology of vibriosis in South Asia.
Methods: For this systematic review and meta-analysis, we searched PubMed, Web of Science, EMBASE, and Google Scholar for studies related to vibriosis in South Asia published up to May 2023. A random-effects meta-analysis was used to estimate the pooled isolation rate of non-cholera-causing Vibrio species.
Results: In total, 38 studies were included. Seven of these were case reports and 22 were included in the meta-analysis. The reported vibriosis cases were caused by non-O1/non-O139 V. cholerae, V. parahaemolyticus, V. fluvialis, and V. vulnificus. The overall pooled isolation rate was 4.0% (95% confidence interval [CI] 3.0-5.0%) in patients with diarrhea. Heterogeneity was high (I-2 = 98.0%). The isolation rate of non-O1/non-O139 V. cholerae, V. parahaemolyticus, and V. fluvialis were 9.0 (95% CI 7.0-10.0%), 1.0 (95% CI 1.0-2.0%), and 2.0 (95% CI: 1.0-3.0%), respectively. Regarding V. parahaemolyticus, O3:K6 was the most frequently isolated serotype. Cases peaked during summer. Several studies reported antibiotic-resistant strains and those harboring extended-spectrum beta-lactamases genes.
Conclusions: This study demonstrates a high burden of infections caused by non-cholera-causing Vibrio species in South Asia. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhatiwadaJanuka en-aut-sei=Khatiwada en-aut-mei=Januka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Social Work Institute kn-affil= affil-num=5 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Vibrio parahaemolyticus kn-keyword=Vibrio parahaemolyticus en-keyword=Vibrio vulnificus kn-keyword=Vibrio vulnificus en-keyword=Vibrio mimicus kn-keyword=Vibrio mimicus en-keyword=Vibrio fluvialis kn-keyword=Vibrio fluvialis en-keyword=Seafood kn-keyword=Seafood en-keyword=Gastroenteritis kn-keyword=Gastroenteritis END start-ver=1.4 cd-journal=joma no-vol=154 cd-vols= no-issue=3 article-no= start-page=209 end-page=217 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Attenuation of protein arginine dimethylation via S-nitrosylation of protein arginine methyltransferase 1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Upregulation of nitric oxide (NO) production contributes to the pathogenesis of numerous diseases via S-nitro- sylation, a post-translational modification of proteins. This process occurs due to the oxidative reaction between NO and a cysteine thiol group; however, the extent of this reaction remains unknown. S-Nitrosylation of PRMT1, a major asymmetric arginine methyltransferase of histones and numerous RNA metabolic proteins, was induced by NO donor treatment. We found that nitrosative stress leads to S-nitrosylation of cysteine 119, located near the active site, and attenuates the enzymatic activity of PRMT1. Interestingly, RNA sequencing analysis revealed similarities in the changes in expression elicited by NO and PRMT1 inhibitors or knockdown. A comprehensive search for PRMT1 substrates using the proximity-dependent biotin identification method highlighted many known and new substrates, including RNA-metabolizing enzymes. To validate this result, we selected the RNA helicase DDX3 and demonstrated that arginine methylation of DDX3 is induced by PRMT1 and attenuated by NO treatment. Our results suggest the existence of a novel regulatory system associated with transcription and RNA metabolism via protein S-nitrosylation. en-copyright= kn-copyright= en-aut-name=TaniguchiRikako en-aut-sei=Taniguchi en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriyaYuto en-aut-sei=Moriya en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DohmaeNaoshi en-aut-sei=Dohmae en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiTakehiro en-aut-sei=Suzuki en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaKengo en-aut-sei=Nakahara en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=4 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=5 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Nitric oxide kn-keyword=Nitric oxide en-keyword=S-Nitrosylation kn-keyword=S-Nitrosylation en-keyword=Protein arginine methyltransferase 1 (PRMT1) kn-keyword=Protein arginine methyltransferase 1 (PRMT1) en-keyword=RNA metabolism kn-keyword=RNA metabolism en-keyword=Dead-box helicase 3X-linxed (DDX3) kn-keyword=Dead-box helicase 3X-linxed (DDX3) END start-ver=1.4 cd-journal=joma no-vol=167 cd-vols= no-issue=1 article-no= start-page=201 end-page=210 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Midline invasion predicts poor prognosis in diffuse hemispheric glioma, H3 G34-mutant: an individual participant data review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Diffuse hemispheric glioma, H3 G34-mutant (DHGs), is a newly categorized tumor in pediatric-type diffuse high-grade gliomas, World Health Organization grade 4, with a poor prognosis. Although prognostic factors associated with genetic abnormalities have been reported, few reports have examined the clinical presentation of DHGs, especially from the viewpoint of imaging findings. In this study, we investigated the relationship between clinical factors, including imaging findings, and prognosis in patients with DHGs.
Methods We searched Medline through the PubMed database using two search terms: “G34” and “glioma”, between 1 April 2012 and 1 July 2023. We retrieved articles that described imaging findings and overall survival (OS), and added one DHG case from our institution. We defined midline invasion (MI) as invasion to the contralateral cerebrum, brainstem, corpus callosum, thalamus, and basal ganglia on magnetic resonance imaging. The primary outcome was 12-month survival, estimated using Kaplan–Meier curves and logistic regression.
Results A total of 96 patients were included in this study. The median age was 22 years, and the proportion of male patients was 48.4%. Lesions were most frequently located in the frontal lobe (52.6%). MI was positive in 39.6% of all patients. The median OS was 14.4 months. Univariate logistic regression analysis revealed that OS was significantly worse in the MI-positive group compared with the MI-negative group. Multivariate logistic regression analysis revealed that MI was an independent prognostic factor in DHGs.
Conclusions In this study, MI-positive cases had a worse prognosis compared with MI-negative cases. en-copyright= kn-copyright= en-aut-name=KegoyaYasuhito en-aut-sei=Kegoya en-aut-mei=Yasuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueYohei en-aut-sei=Inoue en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizutaRyo en-aut-sei=Mizuta en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KoizumiShinichiro en-aut-sei=Koizumi en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanakaYoshihiro en-aut-sei=Tanaka en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Hamamatsu University School of Medicine kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Hamamatsu University School of Medicine kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Division of Epidemiology, Graduate School of Public Health, Shizuoka Graduate University of Public Health kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Diffuse hemispheric gliomas, H3 G34-mutation kn-keyword=Diffuse hemispheric gliomas, H3 G34-mutation en-keyword=Midline invasion kn-keyword=Midline invasion en-keyword=Frontal lobe kn-keyword=Frontal lobe en-keyword=Gross total resection kn-keyword=Gross total resection END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=373 end-page=387 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Male Child Caregivers, Past Trends and Future Perspectives - Literature Review kn-title=男性保育者に関する研究動向と今後の展望 en-subtitle= kn-subtitle= en-abstract=The purpose of this review was to identify research trends from previous studies on male child caregivers and to identify remaining issues for the future. Eighty-four reports were selected from the CiNii Research, which first searched the target literature using "male child caregiver" as a keyword. These articles have been grouped into eight categories based on their content. An examination of these categorized articles reveals that there is limited research from the perspective of the men who provide care, while the situation in childcare settings and the public's perceptions of male childcare providers are relatively clear. As future issues, it is necessary to re-examine the social perceptions surrounding male childcare workers, and to clarify the self-perceptions and challenges these workers face in finding fulfillment in the child care profession. kn-abstract=　本研究は、男性保育者を対象とした先行研究から、研究動向を明らかにし今後の課題を展望することを目的とした。対象文献は、CiNii Research を用いて、「男性保育者」をキーワードとして設定し検索したところ、84件が分析対象となった。対象文献を内容ごとに整理した結果、８つに分類することができた。各分類から、男性保育者に対する保育現場及び社会の認識は比較的明らかにされていたが、男性保育者自身の視点に焦点を当てた研究は十分でないことが明らかとなった。今後は、誕生して50年以上が経過した男性保育者を取り巻く周囲の認識の現状を改めて検討するとともに、男性保育者が保育職にやりがいを感じ、長期的なキャリアを築くにあたっての自己認識及び男性保育者が抱える課題の明確化が必要と考えられた。 en-copyright= kn-copyright= en-aut-name=KURIHARAKyogo en-aut-sei=KURIHARA en-aut-mei=Kyogo kn-aut-name=栗原匡虎 kn-aut-sei=栗原 kn-aut-mei=匡虎 aut-affil-num=1 ORCID= en-aut-name=HASUIKazuya en-aut-sei=HASUI en-aut-mei=Kazuya kn-aut-name=蓮井和也 kn-aut-sei=蓮井 kn-aut-mei=和也 aut-affil-num=2 ORCID= en-aut-name=KATAYAMAMika en-aut-sei=KATAYAMA en-aut-mei=Mika kn-aut-name=片山美香 kn-aut-sei=片山 kn-aut-mei=美香 aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University Graduate School of Education Graduate Student kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Kawasaki University of Medical Welfare kn-affil=川崎医療福祉大学 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=男性保育者 (male child caregiver) kn-keyword=男性保育者 (male child caregiver) en-keyword=研究動向 (research trends) kn-keyword=研究動向 (research trends) en-keyword=文献研究 (literature review) kn-keyword=文献研究 (literature review) en-keyword=展望 (future perspectives) kn-keyword=展望 (future perspectives) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=22 article-no= start-page=7031 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Epidemiology and Reporting Characteristics of Systematic Reviews in Orthopedic Journals: A Meta-Epidemiological Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Systematic reviews (SRs) with complete reporting or rigorous methods can lead to less biased recommendations and decisions. A comprehensive analysis of the epidemiological and reporting characteristics of SRs in orthopedics is lacking. We evaluated 360 SRs, including 165 and 195 published in orthopedic journals in 2012 and 2022. According to the established reporting guidelines, we examined these SRs for key epidemiological characteristics, including focus areas, type of meta-analysis (MA), and reporting characteristics. Most SRs (71%) were therapy-related, with a significant proportion originating from authors in the USA, UK, and China. Pairwise MA was performed on half of the SRs. The proportion of protocol registrations improved by 2022 but remained low (33%). Despite a formal declaration of adherence to the reporting guidelines (68%), they were often not used and reported enough. Only 10% of the studies used full search strategies, including trial registries. Publication bias assessments, subgroup analyses, and sensitivity analyses were not even planned. The risk of bias assessment improved in 2022; however, the certainty of the evidence remained largely unassessed (8%). The use and reporting of standard methods in orthopedic SRs have remained suboptimal. Thus, authors, peer reviewers, journal editors, and readers should criticize the results more. en-copyright= kn-copyright= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaitoShunsuke en-aut-sei=Taito en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiuraTakanori en-aut-sei=Miura en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AriieTakashi en-aut-sei=Ariie en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomitaYosuke en-aut-sei=Tomita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgiharaHirofumi en-aut-sei=Ogihara en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShiratsuchiDaijo en-aut-sei=Shiratsuchi en-aut-mei=Daijo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsujimotoYasushi en-aut-sei=Tsujimoto en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=3 en-affil=Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=4 en-affil=Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=5 en-affil=Department of Physical Therapy, Faculty of Health Care, Takasaki University of Health and Welfare kn-affil= affil-num=6 en-affil=Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=7 en-affil=Graduate School of Health Sciences, Kagoshima University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= en-keyword=meta-analysis kn-keyword=meta-analysis en-keyword=systemic reviews kn-keyword=systemic reviews en-keyword=reporting guidelines kn-keyword=reporting guidelines en-keyword=PRISMA kn-keyword=PRISMA en-keyword=full search strategy kn-keyword=full search strategy END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue= article-no= start-page=49 end-page=54 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Identification of novel early flowering genes in tetraploid wheat (Triticum turgidum L.) and development of efficient methods for their genetic analysis kn-title=四倍体コムギが保有する新規早生遺伝子の探索およびその効率的遺伝解析法の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Wheat (Triticum spp.) is one of the world's three major cereals and a staple food for more than 35% of the world's population, and while nearly doubling crop yields is essential to meet the caloric demands of a growing population by 2050, current rates of wheat yield growth are insufficient to meet this demand. Therefore, it is important to promote the improvement of wheat varieties and to increase yields in a stable manner by utilizing all available genetic resources. Here I would like to introduce some research that has been conducted in this regard, using tetraploid wheat (Triticum turgidum L.) as a genetic resource in the search for genes related to flowering time and the research related to the streamlined genetic analysis technique. en-copyright= kn-copyright= en-aut-name=NishimuraKazusa en-aut-sei=Nishimura en-aut-mei=Kazusa kn-aut-name=西村和紗 kn-aut-sei=西村 kn-aut-mei=和紗 aut-affil-num=1 ORCID= affil-num=1 en-affil=Course of Applied Plant Science kn-affil=応用植物科学コース en-keyword=Wheat kn-keyword=Wheat en-keyword=Tetraploid wheat kn-keyword=Tetraploid wheat en-keyword=Flowering time kn-keyword=Flowering time en-keyword=Allopolyploid kn-keyword=Allopolyploid en-keyword=MIG-seq kn-keyword=MIG-seq END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue= article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluator of adaptability of S. cerevisiae to grape juice using the oversxpression profiling ADOPT method kn-title=過剰発現プロファイリングADOPT法を用いたS.cerevisiaeのワイン醸造用ブドウ果汁への適応性評価 en-subtitle= kn-subtitle= en-abstract=筆者らは最近，過剰発現プロファイリングADOPT 法を開発した．ADOPT 法では，出芽酵母Saccharomyces cerevisiae ゲノムのほとんどの遺伝子をそれぞれ過剰発現する酵母株を混合・競合培養し，その過程で濃縮されてきた株が過剰発現している遺伝子を体系的に同定する．さらに同定された遺伝子をたよりに，S. cerevisiae の与えられた条件での増殖に必要だが欠落しているボトルネック因子を明らかにできる．これまでの研究では，実験室で人為的に構築したストレス環境でのボトルネックの同定を行ってきたが，本研究では産業上のボトルネックを明らかにできるかをワイン醸造用のブドウ果汁を例として検証した．通常のワイン醸造に用いられる亜硫酸添加ブドウ果汁でのADOPT 実験は，亜硫酸ポンプSSU1とその転写因子FZF1の過剰発現株が強く濃縮された．SSU1機能の強化はワイン用酵母の馴養でも起きることが知られていることから，産業上のボトルネックを探索する際にもADOPT が有効であることが示された．一方，亜硫酸添加のないブドウ果汁ではADOPT で強く濃縮された遺伝子は見られず，ブドウ果汁はS. cerevisiae の増殖にとってボトルネックの少ないバランスのとれた培地であることが示唆された． kn-abstract=The authors have recently developed the overexpression profiling ADOPT method. In the ADOPT method, yeast strains overexpressing most of the genes in the budding yeast Saccharomyces cerevisiae genome are mixed and competitively cultured, and the genes overexpressed in the enriched strains are systematically identified. Furthermore, the identified genes can be used to identify bottleneck factors that are necessary but lacking for growth of S. cerevisiae under given conditions. In our previous studies, we have identified bottlenecks in artificially created stress environments in the laboratory, but in this study, we used grape juice for winemaking as an example to see if industrial bottlenecks can be identified. ADOPT experiments with sulfite-added grape juice used in conventional winemaking resulted in a strong enrichment of strains overexpressing the sulfite pump SSU1 and its transcription factor FZF1. Since enhancement of SSU1 function is known to occur in wine yeast acclimation, ADOPT was also shown to be useful in the search for industrial bottlenecks. On the other hand, no genes were strongly enriched by ADOPT in grape juice without sulfite addition, suggesting that grape juice is a balanced medium with few bottlenecks for S. cerevisiae growth. en-copyright= kn-copyright= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name=守屋央朗 kn-aut-sei=守屋 kn-aut-mei=央朗 aut-affil-num=1 ORCID= en-aut-name=OnoChiyuki Kohata en-aut-sei=Ono en-aut-mei=Chiyuki Kohata kn-aut-name=小野千由貴 kn-aut-sei=小野 kn-aut-mei=千由貴 aut-affil-num=2 ORCID= affil-num=1 en-affil=Course of Agrochemical Bioscience kn-affil=農芸化学コース affil-num=2 en-affil=Course of Agrochemical Bioscience kn-affil=農芸化学コース en-keyword=yeast kn-keyword=yeast en-keyword=S. cerevisiae kn-keyword=S. cerevisiae en-keyword=overexpression kn-keyword=overexpression en-keyword=wine making kn-keyword=wine making END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=e914 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical parameter-guided initial resuscitation in adult patients with septic shock: A systematic review and network meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: To identify the most useful tissue perfusion parameter for initial resuscitation in sepsis/septic shock adults using a network meta-analysis.
Methods: We searched major databases until December 2022 for randomized trials comparing four tissue perfusion parameters or against usual care. The primary outcome was short-term mortality up to 90 days. The Confidence in Network Meta-Analysis web application was used to assess the quality of evidence.
Results: Seventeen trials were identified. Lactate-guided therapy (risk ratios, 0.59; 95% confidence intervals [0.45–0.76]; high certainty) and capillary refill time-guided therapy (risk ratios, 0.53; 95% confidence intervals [0.33–0.86]; high certainty) were significantly associated with lower short-term mortality compared with usual care, whereas central venous oxygen saturation-guided therapy (risk ratio, 1.50; 95% confidence intervals [1.16–1.94]; moderate certainty) increased the risk of short-term mortality compared with lactate-guided therapy.
Conclusions: Lactate or capillary refill time-guided initial resuscitation for sepsis/septic shock patients may decrease short-term mortality. More research is essential to personalize and optimize treatment strategies for septic shock resuscitation. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuribaraTomoki en-aut-sei=Kuribara en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKohei en-aut-sei=Yamada en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoTakehito en-aut-sei=Sato en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobaShigeru en-aut-sei=Koba en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TetsuharaKenichi en-aut-sei=Tetsuhara en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KashiuraMasahiro en-aut-sei=Kashiura en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakurayaMasaaki en-aut-sei=Sakuraya en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=School of Nursing, Sapporo City University kn-affil= affil-num=3 en-affil=Department of Traumatology and Critical Care Medicine, National Defense Medical College Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology, Nagoya University Hospital kn-affil= affil-num=5 en-affil=Department of Critical Care Medicine, Nerima Hikarigaoka Hospital kn-affil= affil-num=6 en-affil=Department of Critical Care Medicine, Fukuoka Children's Hospital kn-affil= affil-num=7 en-affil=Department of Emergency and Critical Care Medicine, Saitama Medical Center, Jichi Medical University kn-affil= affil-num=8 en-affil=Department of Emergency and Intensive Care Medicine, JA Hiroshima General Hospital kn-affil= en-keyword=capillary refill timecarbon dioxide gapcentral venous oxygen saturationlactatenetwork meta-analysissepsisseptic shock kn-keyword=capillary refill timecarbon dioxide gapcentral venous oxygen saturationlactatenetwork meta-analysissepsisseptic shock END start-ver=1.4 cd-journal=joma no-vol=142 cd-vols= no-issue= article-no= start-page=106433 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=EpEX, the soluble extracellular domain of EpCAM, resists cetuximab treatment of EGFR-high head and neck squamous cell carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Cetuximab (Cmab) is a molecularly targeted monoclonal antibody drug for head and neck squamous cell carcinoma (HNSC), although cetuximab resistance is a serious challenge. Epithelial cell adhesion molecule (EpCAM) is an established marker for many epithelial tumors, while the soluble EpCAM extracellular domain (EpEX) functions as a ligand for epidermal growth factor receptor (EGFR). We investigated the expression of EpCAM in HNSC, its involvement in Cmab action, and the mechanism by which soluble EpEX activated EGFR and played key roles in Cmab resistance.
Materials and methods: We first examined EPCAM expression in HNSCs and its clinical significance by searching gene expression array databases. We then examined the effects of soluble EpEX and Cmab on intracellular signaling and Cmab efficacy in HNSC cell lines (HSC-3 and SAS).
Results: EPCAM expression was found to be enhanced in HNSC tumor tissues compared to normal tissues, and the enhancement was correlated with stage progression and prognosis. Soluble EpEX activated the EGFR-ERK signaling pathway and nuclear translocation of EpCAM intracellular domains (EpICDs) in HNSC cells. EpEX resisted the antitumor effect of Cmab in an EGFR expression-dependent manner.
Conclusion: Soluble EpEX activates EGFR to increase Cmab resistance in HNSC cells. The EpEX-activated Cmab resistance in HNSC is potentially mediated by the EGFR-ERK signaling pathway and the EpCAM cleavage-induced nuclear translocation of EpICD. High expression and cleavage of EpCAM are potential biomarkers for predicting the clinical efficacy and resistance to Cmab. en-copyright= kn-copyright= en-aut-name=UmemoriKoki en-aut-sei=Umemori

Extended-spectrum β-lactamases-producing Enterobacteriaceae (ESBL-E) is a critical antimicrobial resistance pathogen, to which we need to pay the greatest attention. This study was aimed at uncovering the present evidence for the preventive effectiveness of contact precautions for patients colonized or infected with ESBL-E.
Methods: According to the Preferred Reporting Items for Systemic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews, we searched MEDLINE for articles with relevant keywords from the beginning of 2010 to October 18, 2022.
Results: Of the 355 articles found, 9, including 8 observational studies and 1 randomized controlled trial, were selected. Safety of discontinuing contact precautions was evaluated mainly in acute-care and long-term care hospitals. Consistently, all authors concluded that contact precautions can be safely discontinued in patients colonized or infected with ESBL-E.
Conclusion: The clinical impact of discontinuing contact precautions for patients with ESBL-E is minimal and can be safely withdrawn at acute, noncritical, adult care wards. Relevant data from pediatric and geriatric wards, as well as intensive care units, were insufficient and should be investigated in future research. 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=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=Contact isolation kn-keyword=Contact isolation en-keyword=Health care-associated infection kn-keyword=Health care-associated infection en-keyword=Standard precautions kn-keyword=Standard precautions END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=10 article-no= start-page=1024 end-page=1034 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Up-to-date evidence on image-guided thermal ablation for metastatic lung tumors: a review en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this review was to summarize the latest evidence on image-guided thermal ablation therapies for lung metastases. PubMed was used to search for relevant articles that reported the oncological outcomes of thermal ablation for metastatic lung tumors, and those published in 2010 or later were selected for review. Ablative therapies were applied for lung metastases from various types of primary tumors, but most commonly colorectal ones. Radiofrequency ablation (RFA) was the most evaluated technique, followed by microwave ablation (MWA). The local control rates of ablative therapies were generally favorable, approximately 80–90% in many studies. Representative studies demonstrated promising overall survival rates of approximately 50% or higher 5 years after ablation for lung metastases from colorectal cancer or mixed types of primary tumors. Nevertheless, the survival outcomes varied depending on the type of primary tumor and background factors of patients such as other metastases and comorbidities. Several studies had aimed to compare the outcomes of various ablative therapies such as RFA, MWA, and cryoablation; however, conclusive data are not yet available to determine the most appropriate ablation modality for lung metastases. Further data accumulation is needed, especially for long-term outcomes and comparisons with other therapies. en-copyright= kn-copyright= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawabataTakahiro en-aut-sei=Kawabata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagataShoma en-aut-sei=Nagata en-aut-mei=Shoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Ablation kn-keyword=Ablation en-keyword=Lung kn-keyword=Lung en-keyword=Pulmonary kn-keyword=Pulmonary en-keyword=Metastasis kn-keyword=Metastasis END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=4 article-no= start-page=JAMDSM0035 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adaptive heterogeneous particle swarm optimization with comprehensive learning strategy en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes an adaptive heterogeneous particle swarm optimization with a comprehensive learning strategy for solving single-objective constrained optimization problems. In this algorithm, particles can use an exploration strategy and an exploitation strategy to update their positions. The historical success rates of the two strategies are used to adaptively control the adoption rates of strategies in the next iteration. The search strategy in the canonical particle swarm optimization algorithm is based on elite solutions. As a result, when no particles can discover better solutions for several generations, this algorithm is likely to fall into stagnation. To respond to this challenge, a new strategy is proposed to explore the neighbors of the elite solutions in this study. Finally, a constraint handling method is equipped to the proposed algorithm to make it be able to solve constrained optimization problems. The proposed algorithm is compared with the canonical particle swarm optimization, differential evolution, and several recently proposed algorithms on the benchmark test suite. The Wilcoxon signed-rank test results show that the proposed algorithm is significantly better on most of the benchmark problems compared with the competitors. The proposed algorithm is also applied to solve two real-world mechanical engineering problems. The experimental results show that the proposed algorithm performs consistently well on these problems. en-copyright= kn-copyright= en-aut-name=LIUZiang en-aut-sei=LIU en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NISHITatsushi en-aut-sei=NISHI en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= en-keyword=Swarm intelligence kn-keyword=Swarm intelligence en-keyword=Particle swarm optimization kn-keyword=Particle swarm optimization en-keyword=Differential evolution kn-keyword=Differential evolution en-keyword=Comprehensive learning kn-keyword=Comprehensive 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=2005 dt-pub=20050930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=初心操作者指向の捜索レスキューロボットのインターフェース kn-title=Novice-oriented human interface for a search and rescue robot system en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YangZhixiao en-aut-sei=Yang en-aut-mei=Zhixiao kn-aut-name=楊志曉 kn-aut-sei=楊 kn-aut-mei=志曉 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=951 cd-vols= no-issue=2 article-no= start-page=L27 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Search for Astrophysical Electron Antineutrinos in Super-Kamiokande with 0.01% Gadolinium-loaded Water en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the first search result for the flux of astrophysical electron antineutrinos for energies O(10) MeV in the gadolinium-loaded Super-Kamiokande (SK) detector. In 2020 June, gadolinium was introduced to the ultrapure water of the SK detector in order to detect neutrons more efficiently. In this new experimental phase, SK-Gd, we can search for electron antineutrinos via inverse beta decay with efficient background rejection thanks to the high efficiency of the neutron tagging technique. In this paper, we report the result for the initial stage of SK-Gd, during 2020 August 26, and 2022 June 1 with a 22.5 x 552 kton center dot day exposure at 0.01% Gd mass concentration. No significant excess over the expected background in the observed events is found for the neutrino energies below 31.3 MeV. Thus, the flux upper limits are placed at the 90% confidence level. The limits and sensitivities are already comparable with the previous SK result with pure water (22.5 x 2970 kton center dot day) owing to the enhanced neutron tagging. Operation with Gd increased to 0.03% started in 2022 June. en-copyright= kn-copyright= en-aut-name=HaradaM. en-aut-sei=Harada en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=825 end-page=846 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Data-driven evolutionary computation for service constrained inventory optimization in multi-echelon supply chains en-subtitle= kn-subtitle= en-abstract= kn-abstract=Supply chain digital twin has emerged as a powerful tool in studying the behavior of an actual supply chain. However, most studies in the field of supply chain digital twin have only focused on what-if analysis that compares several different scenarios. This study proposes a data-driven evolutionary algorithm to efficiently solve the service constrained inventory optimization problem using historical data that generated by supply chain digital twins. The objective is to minimize the total costs while satisfying the required service level for a supply chain. The random forest algorithm is used to build surrogate models which can be used to estimate the total costs and service level in a supply chain. The surrogate models are optimized by an ensemble approach-based differential evolution algorithm which can adaptively use different search strategies to improve the performance during the computation process. A three-echelon supply chain digital twin on the geographic information system (GIS) map in real-time is used to examine the efficiency of the proposed method. The experimental results indicate that the data-driven evolutionary algorithm can reduce the total costs and maintain the required service level. The finding suggests that our proposed method can learn from the historical data and generate better inventory policies for a supply chain digital twin. en-copyright= kn-copyright= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi 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=Evolutionary algorithm kn-keyword=Evolutionary algorithm en-keyword=Inventory management kn-keyword=Inventory management en-keyword=Data-driven kn-keyword=Data-driven en-keyword=Supply chain kn-keyword=Supply chain en-keyword=Digital twin kn-keyword=Digital twin END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=395 end-page=405 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Tumor Necrosis Factor-Alpha with Psychopathology in Patients with Schizophrenia en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the relationship between serum tumor necrosis factor-alpha (TNF-α) levels and psychopathological symptoms, clinical and socio-demographic characteristics and antipsychotic therapy in individuals with schizophrenia.

No significant differences in TNF-α levels were detected between the patients and controls (p=0.736). TNF-α levels were not correlated with total, positive, negative, general, or composite PANSS scores (all p>0.05). A significant negative correlation was observed between TNF-α levels and the PANSS cognitive factor (ρ=−0.222, p=0.035). A hierarchical regression analysis identified the cognitive factor as a significant predictor of the TNF-α level (beta=−0.258, t=−2.257, p=0.027). There were no significant differences in TNF-α levels among patients treated with different types of antipsychotics (p=0.596). TNF-α levels correlated positively with the age of onset (ρ=0.233, p=0.027) and negatively with illness duration (ρ=−0.247, p=0.019) and antipsychotic treatment duration (ρ=−0.256, p=0.015). These results indicate that TNF-α may be involved in cognitive impairment in schizophrenia, and would be a potential clinical-state marker in schizophrenia. en-copyright= kn-copyright= en-aut-name=PavlovicMarko en-aut-sei=Pavlovic en-aut-mei=Marko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabicDragan en-aut-sei=Babic en-aut-mei=Dragan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RastovicPejana en-aut-sei=Rastovic en-aut-mei=Pejana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArapovicJurica en-aut-sei=Arapovic en-aut-mei=Jurica kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MartinacMarko en-aut-sei=Martinac en-aut-mei=Marko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JakovacSanja en-aut-sei=Jakovac en-aut-mei=Sanja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BarbaricRomana en-aut-sei=Barbaric en-aut-mei=Romana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=2 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=3 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=4 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=5 en-affil=Health Care Center Mostar, University of Mostar kn-affil= affil-num=6 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=7 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= en-keyword=tumor necrosis factor-alpha kn-keyword=tumor necrosis factor-alpha en-keyword=schizophrenia kn-keyword=schizophrenia en-keyword=psychopathology kn-keyword=psychopathology en-keyword=immune system kn-keyword=immune system END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=387 end-page=394 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Radon Hot Spring Bathing and Health Conditions: A Cross-Sectional Study in Misasa, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=No epidemiological studies have examined the health effects of daily bathing in radon hot springs. In this cross-sectional study, we investigated the associations between radon hot spring bathing and health conditions. The target population was 5,250 adults ≥ 20 years old in the town of Misasa, Japan. We collected information about the participants’ bathing habits and alleviation of a variety of disease symptoms, and their self-rated health (SRH). Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated. In both the adjusted and unadjusted models of hypertension, significant associations between the > 1×/week hot spring bathing and the alleviation of hypertension symptoms were observed compared to the group whose hot spring bathing was <1×/week: adjusted model, OR 5.40 (95%CI: 1.98-14.74); unadjusted model, 3.67 (1.50-8.99) and for gastroenteritis: adjusted model, 9.18 (1.15-72.96); unadjusted model, 7.62 (1.59-36.49). Compared to the no-bathing group, higher SRH was significantly associated with both bathing < 1×/week: unadjusted model, 2.27 (1.53-3.37) and > 1×/week: adjusted model, 1.91 (1.15-3.19). These findings suggest that bathing in radon hot springs is associated with higher SRH and the alleviation of hypertension and gastroenteritis. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiKaito en-aut-sei=Murakami en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoYuki en-aut-sei=Fujimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YukimineRyohei en-aut-sei=Yukimine en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Longevity and Social Medicine (Geriatrics), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=radon hot spring kn-keyword=radon hot spring en-keyword=bathing habit kn-keyword=bathing habit en-keyword=self-rated health kn-keyword=self-rated health en-keyword=cross-section study kn-keyword=cross-section study END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue= article-no= start-page=102233 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safety and usefulness of nebulized liposomal amphotericin B: Systematic scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
Invasive fungal infections potentially result in fatal outcomes in immunocompromised hosts. Compared to intravenous administration, a nebulization therapy can achieve a high concentration of drug delivered in the respiratory tract, without a systematic absorption. We herein summarized the study findings on the safety and clinical utility of nebulized liposomal amphotericin B therapy.
Methods
According to the PRISMA Extension for Scoping Reviews, we performed a search on MEDLINE and EMBASE for articles with relevant keywords, including “inhaled liposomal amphotericin B″, “nebulized liposomal amphotericin B″, or “aerosolized liposomal amphotericin B″, from the inception of these databases to August 31, 2022.
Results
Of the 172 articles found, 27 articles, including 13 case reports, 11 observational studies, and 3 clinical trials, were selected. Generally, findings showed that nebulized liposomal amphotericin B treatment appeared to be safe and without severe adverse effects. We found an accumulated evidence for the safety, tolerability, and effectiveness of nebulized liposomal amphotericin B prophylaxis among lung transplantation recipients; however, a randomized controlled study has yet to be reported. Data on hemato-oncological patients are relatively scarce; however, a randomized controlled study suggested the prophylactic effect of nebulized liposomal amphotericin B on invasive pulmonary aspergillosis. Observational and randomized controlled studies to evaluate therapeutic efficacy of the nebulized liposomal amphotericin B therapy have not been performed.
Conclusion
In conclusion, we found increasing evidence for the effectiveness of the inhalation therapy among patients after lung transplantation and with hemato-oncological diseases. 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=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= en-keyword=Amphotericin B kn-keyword=Amphotericin B en-keyword=Fungal infection kn-keyword=Fungal infection en-keyword=Inhalation kn-keyword=Inhalation en-keyword=Nebulization kn-keyword=Nebulization en-keyword=Aerosolization kn-keyword=Aerosolization END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=5 article-no= start-page=101485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of the comprehensive geriatric assessment in the administration of chemotherapy to older adults with cancer: Recommendations by the Japanese Geriatric Oncology Guideline Committee en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The number of older patients with cancer is expected to continue to increase owing to the aging population. Recently, the usefulness of geriatric assessment (GA) conducted by multiple staff members from different medical backgrounds has been reported; however, a consensus on the effectiveness of GA has not yet been achieved.
Materials and Methods: We, as the Japanese Geriatric Oncology Guideline Committee for elderly patients with cancer, conducted a literature search of randomized controlled trials published before August 2021 that used GA or comprehensive GA (CGA) as an intervention for patients with cancer undergoing chemotherapy. As the key outcomes for answering the clinical question, we focused on survival benefit, adverse events, and quality of life (QOL). After a systematic review of these studies, the expert panel member developed recommendations according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.
Results: For older patients with cancer, GA or CGA is suggested during or before chemotherapy (weakly recommended). Chemotherapy-induced adverse events were significantly reduced by GA/CGA interventions without any adverse effects on survival. Health-related QOL tended to improve with the GA/CGA interventions.
Discussion: Although, in our opinion, GA/CGA does require time and resources, it poses no harm patients. Therefore, we suggest expanding the human resources and educating skills of medical providers for clinical implementation of GA/CGA. en-copyright= kn-copyright= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueDaisuke en-aut-sei=Inoue en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugimotoKen en-aut-sei=Sugimoto en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurofushiKeiko en-aut-sei=Murofushi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkuyamaToru en-aut-sei=Okuyama en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanukiShigeaki en-aut-sei=Watanuki en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ImamuraChiyo K. en-aut-sei=Imamura en-aut-mei=Chiyo K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakaiDaisuke en-aut-sei=Sakai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakuraiNaomi en-aut-sei=Sakurai en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WatanabeKiyotaka en-aut-sei=Watanabe en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TamuraKazuo en-aut-sei=Tamura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SaekiToshiaki en-aut-sei=Saeki en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IshiguroHiroshi en-aut-sei=Ishiguro en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, University of Fukui kn-affil= affil-num=3 en-affil=Department of General Geriatric Medicine, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Division of Radiation Oncology, Department of Radiology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital kn-affil= affil-num=6 en-affil=Department of Psychiatry / Palliative Care Center, Nagoya City University West Medical Center kn-affil= affil-num=7 en-affil=National Center for Global Health and Medicine, National College of Nursing kn-affil= affil-num=8 en-affil=Advanced Cancer Translational Research Institute, Showa University kn-affil= affil-num=9 en-affil=Department of Frontier Science for Cancer and Chemotherapy, Osaka University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Cancer Solutions Co.,Ltd kn-affil= affil-num=11 en-affil=Division of Medical Oncology, Department of Medicine, School of Medicine, Teikyo University kn-affil= affil-num=12 en-affil=NPO Clinical Hematology/Oncology Treatment Study Group kn-affil= affil-num=13 en-affil=Breast Oncology Service, Saitama Medical University International Medical Center kn-affil= affil-num=14 en-affil=Breast Oncology Service, Saitama Medical University International Medical Center kn-affil= en-keyword=Comprehensive geriatric assessment kn-keyword=Comprehensive geriatric assessment en-keyword=Guideline kn-keyword=Guideline en-keyword=Systematic review kn-keyword=Systematic review END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue= article-no= start-page=102554 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Shigellosis in Southeast Asia: A systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Southeast Asia is attractive for tourism. Unfortunately, travelers to this region are at risk of becoming infected with Shigella. We conducted a meta-analysis to provide updates on Shigella prevalence in Southeast Asia, along with their serogroups and serotypes.
Methods: We conducted a systematic search using PubMed, EMBASE, and Web of Science for peer-reviewed studies from 2000 to November 2022. We selected studies that detected Shigella in stools by culture or polymerase chain reaction (PCR). Two reviewers extracted the data using a standardized form and performed quality assessments using the Joanna Briggs Institute checklist. The random effects model was used to estimate the pooled prevalence of Shigella.
Results: During our search, we identified 4376 studies. 29 studies (from six Southeast Asian countries) were included in the systematic review, 21 each in the meta-analysis of the prevalence of Shigella (Sample size: 109545) and the prevalence of Shigella serogroups.
The pooled prevalence of Shigella was 4% (95% CI: 4–5%) among diarrhea cases. Shigella sonnei was the most abundant serogroup in Thailand (74%) and Vietnam (57%), whereas Shigella flexneri was dominant in Indonesia (72%) and Cambodia (71%). Shigella dysenteriae and Shigella boydii were uncommon (pooled prevalence of 1% each). The pooled prevalence of Shigella was 5% (95% CI: 4–6%) in children aged <5 years. The pooled prevalence showed a decreasing trend comparing data collected between 2000–2013 (5%; 95% CI: 4–6%) and between 2014–2022 (3%; 95% CI: 2–4%). Shigella prevalence was 6% in studies that included participants with mixed pathogens versus 3% in those without. Shigella flexneri serotype 2a was the most frequently isolated (33%), followed by 3a (21%), 1b (10%), 2b (3%), and 6 (3%).
Conclusions: This study provides compelling evidence for the development of effective Shigella vaccines for residents of endemic regions and travellers to these areas. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitraDebmalya en-aut-sei=Mitra en-aut-mei=Debmalya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KhatiwadaJanuka en-aut-sei=Khatiwada en-aut-mei=Januka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= 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=Collaborative Research Centre of Okayama University for Infectious Diseases in India at ICMR-NICED kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Social Work Institute kn-affil= affil-num=6 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Shigella vaccine kn-keyword=Shigella vaccine en-keyword=Shigella sonnei kn-keyword=Shigella sonnei en-keyword=Shigella flexneri kn-keyword=Shigella flexneri en-keyword=Diarrhea kn-keyword=Diarrhea en-keyword=Dysentery kn-keyword=Dysentery en-keyword=Shiga toxin kn-keyword=Shiga toxin en-keyword=Travel kn-keyword=Travel END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=49 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Onset time and location of the main rupture of the 2018 Hokkaido Eastern Iburi, Japan, earthquake kn-title=2018 年北海道胆振東部地震の初期の破壊過程 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The rupture process at the beginning stage of the 2018 Hokkaido Eastern Iburi, Japan, earthquake (MJ 6.7) is investigated by analyzing P-wave records from local strong-motion stations. The records show about 3 s of small amplitude arrival (so-called "initial rupture phase") followed by the onset of the main energy release ("main rupture phase"). In this paper we address the issue: where the seismic energy release corresponding to the main rupture phase started at the primary stage of the main rupture, by locating the main rupture onset position. For this aim we applied the 2D and the 3D search methods to estimate the relative location of the onset of the main rupture with respect to the hypocenter, and the time difference between them. The 2D method assumes a plausible initial fault plane and locates the main rupture onset position on the initial fault plane, while the 3D method does not require such assumed fault planes. In the 2D method we employed each of the nodal planes of the first-motion focal mechanism as the initial rupture plane. The 3D method was able to give a better solution than the 2D one. It suggests that the main rupture initiation point might not be on the same fault plane as the hypocenter is. The solution shows that the main rupture onset point is 5.8 km southward and 2.5 km upward from the hypocenter, with the rupture time of 3.3 s from the origin time. It is consistent with the previous studies on the relationship between the magnitude and the initial rupture duration. en-copyright= kn-copyright= en-aut-name=KOWARIHirofumi en-aut-sei=KOWARI en-aut-mei=Hirofumi kn-aut-name=小割啓史 kn-aut-sei=小割 kn-aut-mei=啓史 aut-affil-num=1 ORCID= en-aut-name=KOMATSUMasanao en-aut-sei=KOMATSU en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=2 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院自然科学学域 en-keyword=2018 Hokkaido Eastern Iburi earthquake kn-keyword=2018 Hokkaido Eastern Iburi earthquake en-keyword=fault plane kn-keyword=fault plane en-keyword=initial rupture kn-keyword=initial rupture en-keyword=strong motion kn-keyword=strong motion END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=12 article-no= start-page=1852 end-page=1862 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Review of lymphoma in the duodenum: An update of diagnosis and management en-subtitle= kn-subtitle= en-abstract= kn-abstract=The presentation, subtype, and macroscopic images of lymphoma vary depending on the site of the tumor within the gastrointestinal tract.

We found that knockout mutant of RpmJ (L36), a 50S ribosomal protein, exhibited zinc resistance. The rpmJ mutant was sensitive to protein synthesis inhibitors and had altered translation fidelity, indicating ribosomal dysfunction. In the rpmJ mutant, the intracellular zinc concentration was decreased under excess zinc conditions. Knockout of ZntA, a zinc efflux pump, abolished the zinc-resistant phenotype of the rpmJ mutant. RNA sequence analysis revealed that the rpmJ mutant exhibited altered gene expression of diverse functional categories, including translation, energy metabolism, and stress response. These findings suggest that knocking out RpmJ alters gene expression patterns and causes zinc resistance by lowering the intracellular zinc concentration. Knockouts of other ribosomal proteins, including RplA, RpmE, RpmI, and RpsT, also led to a zinc-resistant phenotype, suggesting that deletion of ribosomal proteins is closely related to zinc resistance. en-copyright= kn-copyright= en-aut-name=ShirakawaRiko en-aut-sei=Shirakawa en-aut-mei=Riko 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=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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 Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=1138019 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Parameter search of a CPG network using a genetic algorithm for a snake robot with tactile sensors moving on a soft floor en-subtitle= kn-subtitle= en-abstract= kn-abstract=When a snake robot explores a collapsed house as a rescue robot, it needs to move through various obstacles, some of which may be made of soft materials, such as mattresses. In this study, we call mattress-like environment as a soft floor, which deforms when some force is added to it. We focused on the central pattern generator (CPG) network as a control for the snake robot to propel itself on the soft floor and constructed a CPG network that feeds back contact information between the robot and the floor. A genetic algorithm was used to determine the parameters of the CPG network suitable for the soft floor. To verify the obtained parameters, comparative simulations were conducted using the parameters obtained for the soft and hard floor, and the parameters were confirmed to be appropriate for each environment. By observing the difference in snake robot's propulsion depending on the presence or absence of the tactile sensor feedback signal, we confirmed the effectiveness of the tactile sensor considered in the parameter search. en-copyright= kn-copyright= en-aut-name=TamuraHajime en-aut-sei=Tamura en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=snake robot kn-keyword=snake robot en-keyword=tactile sensor kn-keyword=tactile sensor en-keyword=CPG network kn-keyword=CPG network en-keyword=soft floor kn-keyword=soft floor en-keyword=genetic algorithm kn-keyword=genetic algorithm END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=6 article-no= start-page=5168 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stress-Inducible SCAND Factors Suppress the Stress Response and Are Biomarkers for Enhanced Prognosis in Cancers en-subtitle= kn-subtitle= en-abstract= kn-abstract=The cell stress response is an essential system present in every cell for responding and adapting to environmental stimulations. A major program for stress response is the heat shock factor (HSF)-heat shock protein (HSP) system that maintains proteostasis in cells and promotes cancer progression. However, less is known about how the cell stress response is regulated by alternative transcription factors. Here, we show that the SCAN domain (SCAND)-containing transcription factors (SCAN-TFs) are involved in repressing the stress response in cancer. SCAND1 and SCAND2 are SCAND-only proteins that can hetero-oligomerize with SCAN-zinc finger transcription factors, such as MZF1(ZSCAN6), for accessing DNA and transcriptionally co-repressing target genes. We found that heat stress induced the expression of SCAND1, SCAND2, and MZF1 bound to HSP90 gene promoter regions in prostate cancer cells. Moreover, heat stress switched the transcript variants' expression from long noncoding RNA (lncRNA-SCAND2P) to protein-coding mRNA of SCAND2, potentially by regulating alternative splicing. High expression of HSP90AA1 correlated with poorer prognoses in several cancer types, although SCAND1 and MZF1 blocked the heat shock responsiveness of HSP90AA1 in prostate cancer cells. Consistent with this, gene expression of SCAND2, SCAND1, and MZF1 was negatively correlated with HSP90 gene expression in prostate adenocarcinoma. By searching databases of patient-derived tumor samples, we found that MZF1 and SCAND2 RNA were more highly expressed in normal tissues than in tumor tissues in several cancer types. Of note, high RNA expression of SCAND2, SCAND1, and MZF1 correlated with enhanced prognoses of pancreatic cancer and head and neck cancers. Additionally, high expression of SCAND2 RNA was correlated with better prognoses of lung adenocarcinoma and sarcoma. These data suggest that the stress-inducible SCAN-TFs can function as a feedback system, suppressing excessive stress response and inhibiting cancers. en-copyright= kn-copyright= en-aut-name=ShetaMona en-aut-sei=Sheta en-aut-mei=Mona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaKunihiro en-aut-sei=Yoshida en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanemotoHideka en-aut-sei=Kanemoto en-aut-mei=Hideka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CalderwoodStuart K. en-aut-sei=Calderwood en-aut-mei=Stuart K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EguchiTakanori en-aut-sei=Eguchi en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiation Oncology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=5 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell stress response kn-keyword=cell stress response en-keyword=heat shock protein 90 (HSP90) kn-keyword=heat shock protein 90 (HSP90) en-keyword=SCAN domain (SCAND)-containing proteins kn-keyword=SCAN domain (SCAND)-containing proteins en-keyword=MZF1 kn-keyword=MZF1 en-keyword=ZSCAN6 kn-keyword=ZSCAN6 en-keyword=heat shock factor (HSF) kn-keyword=heat shock factor (HSF) en-keyword=long noncoding RNA (lncRNA) kn-keyword=long noncoding RNA (lncRNA) en-keyword=co-expression correlation kn-keyword=co-expression correlation en-keyword=Kaplan-Meier plot kn-keyword=Kaplan-Meier plot en-keyword=cancer patient prognosis kn-keyword=cancer patient prognosis END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=2023 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Serum sCD40L and IL-31 in Association with Early Phase of IgA Nephropathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: IgA nephropathy (IgAN) is a major cause of chronic glomerulonephritis worldwide. T cell dysregulation has been reported to contribute to the pathogenesis of IgAN. Methods We measured a broad range of Th1, Th2 and Th17 cytokines in the serum of IgAN patients. We searched for significant cytokines, which were associated with clinical parameters and histological scores in IgAN patients. Results: Among 15 cytokines, the levels of soluble CD40L (sCD40L) and IL-31 were higher in IgAN patients and were significantly associated with a higher estimated glomerular filtration rate (eGFR), a lower urinary protein to creatinine ratio (UPCR), and milder tubulointerstitial lesions (i.e., the early phase of IgAN). Multivariate analysis revealed that serum sCD40L was an independent determinant of a lower UPCR after adjustment for age, eGFR, and mean blood pressure (MBP). CD40, a receptor of sCD40L, has been reported to be upregulated on mesangial cells in IgAN. The sCD40L/CD40 interaction may directly induce inflammation in mesangial areas and may therefore be involved in the development of IgAN. Conclusions: The present study demonstrated the significance of serum sCD40L and IL-31 in the early phase of IgAN. Serum sCD40L may be a marker of the beginning of inflammation in IgAN. en-copyright= kn-copyright= en-aut-name=TanakaKeiko en-aut-sei=Tanaka en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiyamaHitoshi en-aut-sei=Sugiyama en-aut-mei=Hitoshi 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=KitagawaMasashi en-aut-sei=Kitagawa en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanoYuzuki en-aut-sei=Kano en-aut-mei=Yuzuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=MiseKoki en-aut-sei=Mise en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=cytokines kn-keyword=cytokines en-keyword=sCD40L kn-keyword=sCD40L en-keyword=IL-31 kn-keyword=IL-31 en-keyword=proteinuria kn-keyword=proteinuria en-keyword=inflammation kn-keyword=inflammation en-keyword=interstitial fibrosis kn-keyword=interstitial fibrosis END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=90 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Autophagy as a potential mechanism underlying the biological effect of 1,25-Dihydroxyvitamin D3 on periodontitis: a narrative review en-subtitle= kn-subtitle= en-abstract= kn-abstract=The major active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25D3), is known for its wide bioactivity in periodontal tissues. Although the exact mechanisms underlying its protective action against periodontitis remain unclear, recent studies have shown that 1,25D3 regulates autophagy. Autophagy is vital for intracellular pathogen invasion control, inflammation regulation, and bone metabolic balance in periodontal tissue homeostasis, and its regulation could be an interesting pathway for future periodontal studies. Since vitamin D deficiency is a worldwide health problem, its role as a potential regulator of autophagy provides new insights into periodontal diseases. Based on this premise, this narrative literature review aimed to investigate the possible connection between 1,25D3 and autophagy in periodontitis. A comprehensive literature search was conducted on PubMed using the following keywords (e.g., vitamin D, autophagy, periodontitis, pathogens, epithelial cells, immunity, inflammation, and bone loss). In this review, the latest studies on the protective action of 1,25D3 against periodontitis and the regulation of autophagy by 1,25D3 are summarized, and the potential role of 1,25D3-activated autophagy in the pathogenesis of periodontitis is analyzed. 1,25D3 can exert a protective effect against periodontitis through different signaling pathways in the pathogenesis of periodontitis, and at least part of this regulatory effect is achieved through the activation of the autophagic response. This review will help clarify the relationship between 1,25D3 and autophagy in the homeostasis of periodontal tissues and provide perspectives for researchers to optimize prevention and treatment strategies in the future. en-copyright= kn-copyright= en-aut-name=ChenXiaoting en-aut-sei=Chen en-aut-mei=Xiaoting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AriasZulema en-aut-sei=Arias en-aut-mei=Zulema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pathophysiology‑Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology‑Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pathophysiology‑Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathophysiology‑Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathophysiology‑Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Vitamin D kn-keyword=Vitamin D en-keyword=Autophagy kn-keyword=Autophagy en-keyword=Periodontitis kn-keyword=Periodontitis en-keyword=Epithelial barrier kn-keyword=Epithelial barrier en-keyword=Immunity kn-keyword=Immunity en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Alveolar bone loss kn-keyword=Alveolar bone loss END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=3 article-no= start-page=1879 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flexible Route Planning for Multiple Mobile Robots by Combining Q-Learning and Graph Search Algorithm en-subtitle= kn-subtitle= en-abstract= kn-abstract=The use of multiple mobile robots has grown significantly over the past few years in logistics, manufacturing and public services. Conflict-free route planning is one of the major research challenges for such mobile robots. Optimization methods such as graph search algorithms are used extensively to solve route planning problems. Those methods can assure the quality of solutions, however, they are not flexible to deal with unexpected situations. In this article, we propose a flexible route planning method that combines the reinforcement learning algorithm and a graph search algorithm for conflict-free route planning problems for multiple robots. In the proposed method, Q-learning, a reinforcement algorithm, is applied to avoid collisions using off-line learning with a limited state space to reduce the total learning time. Each vehicle independently finds the shortest route using the A* algorithm, and Q-learning is used to avoid collisions. The effectiveness of the proposed method is examined by comparing it with conventional methods in terms of computation time and the quality of solutions. Computational results show that for dynamic transportation problems, the proposed method can generate the solutions with approximately 10% of the computation time compared to the conventional Q-learning approach. We found that the required computation time is linearly increased with respect to the number of vehicles and nodes in the problems. en-copyright= kn-copyright= en-aut-name=KawabeTomoya en-aut-sei=Kawabe en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang 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 Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Automated Guided Vehicles kn-keyword=Automated Guided Vehicles en-keyword=route planning kn-keyword=route planning en-keyword=Q-learning kn-keyword=Q-learning en-keyword=reinforcement learning kn-keyword=reinforcement learning en-keyword=transportation kn-keyword=transportation END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=45 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three Diverse Applications of General-Purpose Parameter Optimization Algorithm en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parameters often take key roles in determining the accuracy of algorithms, logics, and models for practical applications. Previously, we have proposed a general-purpose parameter optimization algorithm, and studied its applications in various practical problems. This algorithm optimizes the parameter values by repeating small changes of them based on a local search method with hill-climbing capabilities. In this paper, we present three diverse applications of this algorithm to show the versatility and effectiveness. The first application is the fingerprint-based indoor localization system using IEEE802.15.4 devices called FILS15.4 that can detect the location of a user in an indoor environment. It is shown that the number of fingerprints for each detection point, the fingerprint values, and the detection interval are optimized together, and the average detection accuracy exceeds 99%. The second application is the human face contour approximation model that is described by a combination of half circles, line segments, and a quadratic curve. It is shown that the simple functions can well approximate the face contour of various persons by optimizing the center coordinates, radii, and coefficients. The third application is the computational fluid dynamic (CFD) simulation to estimate temperature changes in a room. It is shown that the thermal conductivity is optimized to make the average temperature difference between the estimated and measured 0.22 ℃. en-copyright= kn-copyright= en-aut-name=HuoYuanzhi en-aut-sei=Huo en-aut-mei=Yuanzhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PuspitaningayuPradini en-aut-sei=Puspitaningayu en-aut-mei=Pradini kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamazakiKazushi en-aut-sei=Hamazaki en-aut-mei=Kazushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuribayashiMinoru en-aut-sei=Kuribayashi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhaoYihan en-aut-sei=Zhao en-aut-mei=Yihan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KojimaKazuyuki en-aut-sei=Kojima en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Mechanical Engineering, Shonan Institute of Technology kn-affil= affil-num=7 en-affil=Department of Mechanical Engineering, Shonan Institute of Technology kn-affil= en-keyword=parameter optimization kn-keyword=parameter optimization en-keyword=application kn-keyword=application en-keyword=indoor localization kn-keyword=indoor localization en-keyword=face contour model kn-keyword=face contour model en-keyword=computational fluid dynamics kn-keyword=computational fluid dynamics END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=108524 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The dataset of Japanese patents and patents' holding firms in green vehicle powertrains field en-subtitle= kn-subtitle= en-abstract= kn-abstract=In 2020, the Government of Japan declared "2050 carbon neutral" and launched a long-term strategy to create a "virtuous cycle of economy and environment".(1) Japanese firms possess many technologies that contribute to decarbonization, which is important to expand investment for Green Technology (environmental technology) development. As automobiles are major contributors to greenhouse gas emissions [1], the technological shift towards vehicle powertrain systems is an attempt to lower problems like emissions of carbon dioxide, nitrogen oxides [2]. On the other hand, patent data are the most reliable business performance for applied research and development activities when investigating the knowledge domains or the technology evolution (Wand, 1997). Our paper describes a Japanese patents dataset of the vehicle powertrain systems for hybrid electric vehicle (HEV), battery electric vehicle (BEV) and fuel cell electric vehicles (FCEV). In this paper we create a method of bombinating international patent classification (IPC) and keywords to define "green" patents in vehicle powertrains field, using patent data which were applied to Japan Patent Office recorded on EPO's PATSTAT database during 2010 similar to 2019 year. When analyze patents, it is necessary to consider the social situation of each country including language background, we collect patents description documents (abstracts and titles) not only written in English but also in Japanese. Finally, we build a database includes 6025 green patents' description documents and 266 patents' holding firms. With which we then identify 3756 HEV patents, 1716 BEV patents, and 553 FCEV patents. Data about patent holding firms is also appended. The full dataset may be useful to researchers who would like to do further search like natural language processing and machine learning on patent description documents, statistical data analysis for empirical economics. en-copyright= kn-copyright= en-aut-name=JiangJiaming en-aut-sei=Jiang en-aut-mei=Jiaming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabaKensuke en-aut-sei=Baba en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhaoYu en-aut-sei=Zhao en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FengJunshi en-aut-sei=Feng en-aut-mei=Junshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumagaiSou en-aut-sei=Kumagai en-aut-mei=Sou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Science, Okayama University kn-affil= affil-num=2 en-affil=Cyber-Physical Engineering Informatics Research Core, Okayama University kn-affil= affil-num=3 en-affil=School of Management, Department of Management, Tokyo University of Science kn-affil= affil-num=4 en-affil=Graduate School of Humanities and Social Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Electrical and Communication Engineering, Faculty of Engineering, Okayama University kn-affil= en-keyword=Patents kn-keyword=Patents en-keyword=Green innovation kn-keyword=Green innovation en-keyword=Vehicle powertrain kn-keyword=Vehicle powertrain en-keyword=Hybrid electric vehicle kn-keyword=Hybrid electric vehicle en-keyword=Battery electric vehicle kn-keyword=Battery electric vehicle en-keyword=Fuel cell electric vehicles kn-keyword=Fuel cell electric vehicles END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=4 article-no= start-page=267 end-page=284 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221018 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Traditional Chinese Medicines and Prescriptions Brought from China to Japan by a Monk (Jianzhen, Japanese: Ganjin): A Historical Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=(1) Background: Japanese Kampo medicine has its origin in ancient Chinese medicine. In 742, a Tang Dynasty monk named Jianzhen (Ganjin) was invited by Japanese clerics to visit Japan and teach commandments in Buddhism. Because of the dangers of the voyage and also other obstacles, he took 11 years to reach Japan on the sixth voyage and he was blind when he arrived in Japan. He was the first person in China to go to Japan to establish the Buddhism commandments, and he was also the first person in Japan to directly teach traditional Chinese medicine. Until now, there have been few reports in English about the details of the Chinese herbal medicines he brought to Japan, including the types of herbal medicines, pharmacological activities, and formulations. In the review, we systematically and comprehensively summarized Jianzhen’s life from the standpoint of his medical and pharmaceutical knowledge and the types and pharmacological activities of Chinese herbal medicines and prescriptions that were brought to Japan by Jianzhen;
(2) Methods: A review was made on the relevant literature written by Chinese, Japanese, and English languages regarding the medical and pharmacological knowledge of Jianzhen, the 36 Chinese herbal medicines brought to Japan by Jianzhen, and the pharmacological and therapeutic effects of these 36 herbal medicines, as well as their formulations;
(3) Results: The review of the literature proved that Jianzhen’s prescriptions served as a basis for current herbal medicines (Kampo) in Japan. In the process of the literature search, we found a book entitled Jianshangren (Holy Priest Jianzhen)’s Secret Prescription, which recorded the complete prescription of the 36 traditional Chinese medicines Jianzhen brought to Japan;
(4) Conclusions: Jianzhen is one of the ancestors of traditional Chinese medicine/Kampo medicine, and he brought traditional Chinese medicine and medical books to Japan for patients. He made important contributions to the development of traditional Chinese medicine in Japan. en-copyright= kn-copyright= en-aut-name=LiuShihui en-aut-sei=Liu en-aut-mei=Shihui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuoChie en-aut-sei=Matsuo en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Jianzhen kn-keyword=Jianzhen en-keyword=Ganjin kn-keyword=Ganjin en-keyword=traditional Chinese medicine kn-keyword=traditional Chinese medicine en-keyword=Kampo medicine kn-keyword=Kampo medicine en-keyword=herbal medicine kn-keyword=herbal medicine en-keyword=medical history kn-keyword=medical history en-keyword=Toshodaiji Temple kn-keyword=Toshodaiji Temple en-keyword=traditional Japanese medicine kn-keyword=traditional Japanese medicine en-keyword=Nara kn-keyword=Nara en-keyword=Tang Dynasty kn-keyword=Tang Dynasty END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=22 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Colonization with extended-spectrum beta-lactamase-producing Escherichia coli and traveler's diarrhea attack rates among travelers to India: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background India is an attractive destination for travelers. Unfortunately, numerous reports exist on traveler's diarrhea (TD) and fecal colonization with extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-EC) among international travelers visiting India. Here, we systematically reviewed studies published on the acquisition of ESBL-EC and TD attack rates among international visitors to India. Methods Design: Systematic review and meta-analysis. A systematic search was performed using Google Scholar, PubMed, EMBASE, Web of Science, and gray literature from 2000 to December 2021, for studies containing data for ESBL-EC acquisition or TD experience related to a trip to India. Random effects models were used to compute the prevalence of ESBL-EC acquisition and TD attack. Results The literature search yielded a total of 5023 records. Of these, 31 met our inclusion criteria for systematic review and only 17 could be meta-analyzed (9 for TD, and 8 for ESBL-EC). The overall pooled attack rate of TD was 39% (95% confidence interval, CI: 25-53%). In studies where travelers' memory was used to diagnose TD, the pooled attack rate of TD was slightly higher (42%, 95% CI: 21-64%) compared to those where TD was objectively documented (33%, 95% CI: 17-49%). There were significant risks to be colonized with ESBL-EC among the travelers who experienced TD. The pooled rate of ESBL-EC colonization was 72% (CI: 67-78%). Most ESBL-EC produced CTX-M-15 enzyme. Furthermore, most of the travelers who acquired ESBL-EC were from highly industrialized countries recruited from travel clinics: Canada (n = 80), Germany (n = 69), Netherlands (n = 20), Sweden (n = 18), Japan (n = 10), Finland (n = 8), USA (n = 7), Spain (n = 5), and Denmark (n = 3). Conclusions TD pooled attack rate and ESBL-EC acquisition among international travelers visiting India were high in this study. However, we cannot make generalizations based upon this TD pooled attack rate for the current situation, due to a lack of current data. Our study highlights that travelers should be advised on TD to ensure that they do not disregard the risk of contracting TD and be better prepared as a result. It also illustrates the importance of international travel in acquiring antibiotic-resistant Escherichia coli. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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 Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ESBL-EC kn-keyword=ESBL-EC en-keyword=Traveler's diarrhea kn-keyword=Traveler's diarrhea en-keyword=International travelers kn-keyword=International travelers en-keyword=India kn-keyword=India en-keyword=Meta-analysis kn-keyword=Meta-analysis END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=18 article-no= start-page=10300 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220907 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histidine-Rich Glycoprotein Suppresses the S100A8/A9-Mediated Organotropic Metastasis of Melanoma Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=The dissection of the complex multistep process of metastasis exposes vulnerabilities that could be exploited to prevent metastasis. To search for possible factors that favor metastatic outgrowth, we have been focusing on secretory S100A8/A9. A heterodimer complex of the S100A8 and S100A9 proteins, S100A8/A9 functions as a strong chemoattractant, growth factor, and immune suppressor, both promoting the cancer milieu at the cancer-onset site and cultivating remote, premetastatic cancer sites. We previously reported that melanoma cells show lung-tropic metastasis owing to the abundant expression of S100A8/A9 in the lung. In the present study, we addressed the question of why melanoma cells are not metastasized into the brain at significant levels in mice despite the marked induction of S100A8/A9 in the brain. We discovered the presence of plasma histidine-rich glycoprotein (HRG), a brain-metastasis suppression factor against S100A8/A9. Using S100A8/A9 as an affinity ligand, we searched for and purified the binding plasma proteins of S100A8/A9 and identified HRG as the major protein on mass spectrometric analysis. HRG prevents the binding of S100A8/A9 to the B16-BL6 melanoma cell surface via the formation of the S100A8/A9 complex. HRG also inhibited the S100A8/A9-induced migration and invasion of A375 melanoma cells. When we knocked down HRG in mice bearing skin melanoma, metastasis to both the brain and lungs was significantly enhanced. The clinical examination of plasma S100A8/A9 and HRG levels showed that lung cancer patients with brain metastasis had higher S100A8/A9 and lower HRG levels than nonmetastatic patients. These results suggest that the plasma protein HRG strongly protects the brain and lungs from the threat of melanoma metastasis. en-copyright= kn-copyright= en-aut-name=TomonobuNahoko en-aut-sei=Tomonobu en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=WakeHidenori en-aut-sei=Wake en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueYusuke en-aut-sei=Inoue en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RumaI.

We aimed to evaluate the impact of cervical cancer awareness months on public attention using Google Trends analysis. Between 2012 and 2021, we analyzed the trends in relative search volumes (RSVs) for "Shikyuu-keigan" (cervical cancer in English) in Japan, during the cervical cancer awareness month (CCAM) in January and cervical cancer prevention awareness enhancement month (CCPAEM) in November. We performed a joinpoint regression analysis to identify a statistically significant trend change point. Additionally, we compared the mean RSVs of each awareness month with the rest of the year. Significant trend change points were observed, but none were found in CCAM and CCPAEM periods. Comparison of mean RSVs among CCAM, CCPAEM, and the rest of the months did not suggest any significant increases in RSVs during these awareness periods. In conclusion, CAM and CCPAEM did not raise public interest in cervical cancer in Japan. Although the results are based on internet users, the findings might suggest a need to develop a more effective and attractive approach to achieve the 90-70-90 targets of cervical cancer prevention by 2030. 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=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=457 end-page=463 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of 0.01% Atropine Eye Drops in Controlling Myopia Progression and Axial Elongation in Children: A Meta-analysis Based on Randomized Controlled Trials en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the preventive effects of 0.01% atropine eye drops against myopia progression and axial elongation in children, a meta-analysis was carried out based on data obtained from PubMed and Web of Science as of August 1, 2021. Randomized controlled trials (RCTs) that enrolled myopic children who had received atropine for at least one year were included in this study, Key search terms included myopia, children, and 0.01% or low-dose atropine. Heterogeneity was quantified by I2 statistics, and meta-analyses were performed using the fixed-effect model. Five RCTs involving 809 unique children were analyzed. One trial was excluded because of a poor Jadad score and markedly rapid myopia progression in controls. The mean effect sizes for 12 months in myopia progression and axial elongation synthesized from the remaining 4 RCTs were 0.20 (95% CI: 0.13 to 0.27) D and −0.08 (−0.11 to −0.04) mm, respectively (p<0.0001). The corresponding inhibition ratios were 28% and 19%. I2 statistics were 6% or less. Sensitivity analysis and funnel plots demonstrated the robustness of the estimation. The 0.01% atropine-induced inhibition ratio for myopia progression in Asian children was roughly half of that originally reported and did not reach the minimum requirement for clinical treatment. en-copyright= kn-copyright= en-aut-name=SunWeiying en-aut-sei=Sun en-aut-mei=Weiying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasebeSatoshi en-aut-sei=Hasebe en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Ophthalmology 2, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Ophthalmology 2, Kawasaki Medical School kn-affil= en-keyword=myopia kn-keyword=myopia en-keyword=0.01% atropine kn-keyword=0.01% atropine en-keyword=low-dose atropine kn-keyword=low-dose atropine en-keyword=axial length kn-keyword=axial length en-keyword=myopia progression kn-keyword=myopia progression END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=399 end-page=408 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gene Expression Profiling between Patient Groups with High and Low Ki67 Levels after Short-term Preoperative Aromatase Inhibitor Treatment for Breast Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=According to a recent report, a low Ki67 level after short-term preoperative hormone therapy (post-Ki67) might suggest a more favorable prognosis compared with a high post-Ki67 level in patients with hormone receptorpositive/human epidermal growth factor 2-negative (HR+/HER2−) breast cancer with high levels of Ki67. This study aimed to evaluate the pre-treatment genetic differences between these two patient groups. Forty-five luminal B-like patients were stratified into two groups, namely, a group with high (H→H) and one with low (H→L) Ki67 levels after short-term preoperative aromatase inhibitor (AI) treatment. We compared pre-treatmentgene expression profiles between the two groups. In gene level analysis, there was no significant difference between the two groups by the class comparison test. In pathway analysis, five metabolism-related gene sets were significantly upregulated in the H→L group (p≤0.05). In the search for novel targets, five genes (PARP, BRCA2, FLT4, CDK6, and PDCD1LG2) showed significantly higher expression in the H→H group (p≤0.05). Several metabolism-related pathways were associated with sensitivity to AI. In the future, it will be necessary to seek out new therapeutic strategies for the poor prognostic group with high post-Ki67. en-copyright= kn-copyright= en-aut-name=KajiwaraYukiko en-aut-sei=Kajiwara en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamotoTakayuki en-aut-sei=Iwamoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhuYidan en-aut-sei=Zhu en-aut-mei=Yidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KochiMariko en-aut-sei=Kochi en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= affil-num=1 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=2 en-affil=Departments of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Departments of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Departments of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Departments of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Departments of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=short-term hormone therapy kn-keyword=short-term hormone therapy en-keyword=gene expression profiling kn-keyword=gene expression profiling en-keyword=Ki-67 kn-keyword=Ki-67 en-keyword=targeted therapy kn-keyword=targeted therapy END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=359 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Therapeutic Approaches Targeting miRNA in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Systemic lupus erythematosus (SLE) is a potentially fatal systemic autoimmune disease, and its etiology involves both genetic and environmental factors such as sex hormone imbalance, genetic predisposition, epigenetic regulation, and immunological factors. Dysregulation of microRNA (miRNA) is suggested to be one of the epigenetic factors in SLE. miRNA is a 22-nucleotide single-stranded noncoding RNA that contributes to post-transcriptional modulation of gene expression. miRNA targeting therapy has been suggested to be useful for the treatment of cancers and other diseases. Gene knockout and miRNA targeting therapy have been demonstrated to improve SLE disease activity in mice. However, these approaches have not yet reached the level of clinical application. miRNA targeting therapy is limited by the fact that each miRNA has multiple targets. In addition, the expression of certain miRNAs may differ among cell tissues within a single SLE patient. This limitation can be overcome by targeted delivery and chemical modifications. In the future, further research into miRNA chemical modifications and delivery systems will help us develop novel therapeutic agents for SLE. en-copyright= kn-copyright= en-aut-name=Hiramatsu-AsanoSumie en-aut-sei=Hiramatsu-Asano en-aut-mei=Sumie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=miRNA kn-keyword=miRNA en-keyword=miRNA targeting therapy kn-keyword=miRNA targeting therapy END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=16 article-no= start-page=4879 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Immediate Postoperative Radiographic Findings and Failed Internal Fixation for Trochanteric Fractures: Systematic Review and Meta-Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Failed internal fixations for trochanteric fractures have a strong negative impact owing to increased postoperative mortality and high medical costs. However, evidence on the prognostic value of postoperative radiographic findings for failed internal fixations is limited. We aimed to clarify the association between comprehensive immediate postoperative radiographic findings and failed internal fixation using relative and absolute risk measures. We followed the meta-analysis of observational studies in epidemiology guidelines and the Cochrane handbook. We searched specific databases in November 2021. The outcomes of interest were failed internal fixation and cut-out. We pooled the odds ratios and 95% confidence intervals using a random-effects model and calculated the number needed to harm for each outcome. Thirty-six studies involving 8938 patients were included. The certainty of evidence in the association between postoperative radiographic findings and failed internal fixation or cut-out was mainly low or very low except for the association between intramedullary malreduction on the anteromedial cortex and failed internal fixation. Moderate certainty of evidence supported that intramedullary malreduction on the anteromedial cortex was associated with failed internal fixation. Most postoperative radiographic findings on immediate postoperative radiographs for trochanteric fractures were uncertain as prognostic factors for failed internal fixations. en-copyright= kn-copyright= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujimotoYasushi en-aut-sei=Tsujimoto en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokooSuguru en-aut-sei=Yokoo en-aut-mei=Suguru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DemiyaKoji en-aut-sei=Demiya en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueMadoka en-aut-sei=Inoue en-aut-mei=Madoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Scientific Research Works Peer Support Group (SRWS-PSG) kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, National Hospital Organization Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=5 en-affil=Scientific Research Works Peer Support Group (SRWS-PSG) kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery and Traumatology, Kawasaki Medical School General Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=trochanteric fracture kn-keyword=trochanteric fracture en-keyword=intertrochanteric fracture kn-keyword=intertrochanteric fracture en-keyword=pertrochanteric fracture kn-keyword=pertrochanteric fracture en-keyword=reduction kn-keyword=reduction en-keyword=tip-apex distance kn-keyword=tip-apex distance en-keyword=mechanical failure kn-keyword=mechanical failure en-keyword=fixation failure kn-keyword=fixation failure en-keyword=cut-out kn-keyword=cut-out en-keyword=systematic review kn-keyword=systematic review en-keyword=meta-analysis kn-keyword=meta-analysis END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=1517 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Correlation between national surveillance and search engine query data on respiratory syncytial virus infections in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The respiratory syncytial virus (RSV) disease burden is significant, especially in infants and children with an underlying disease. Prophylaxis with palivizumab is recommended for these high-risk groups. Early recognition of a RSV epidemic is important for timely administration of palivizumab. We herein aimed to assess the correlation between national surveillance and Google Trends data pertaining to RSV infections in Japan. Methods The present, retrospective survey was performed between January 1, 2018 and November 14, 2021 and evaluated the correlation between national surveillance data and Google Trends data. Joinpoint regression was used to identify the points at which changes in trends occurred. Results A strong correlation was observed every study year (2018 [r = 0.87, p < 0.01], 2019 [r = 0.83, p < 0.01], 2020 [r = 0.83, p < 0.01], and 2021 [r = 0.96, p < 0.01]). The change-points in the Google Trends data indicating the start of the RSV epidemic were observed earlier than by sentinel surveillance in 2018 and 2021 and simultaneously with sentinel surveillance in 2019. No epidemic surge was observed in either the Google Trends or the surveillance data from 2020. Conclusions Our data suggested that Google Trends has the potential to enable the early identification of RSV epidemics. In countries without a national surveillance system, Google Trends may serve as an alternative early warning system. en-copyright= kn-copyright= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YashiroMasato en-aut-sei=Yashiro en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pediatrics Acute Diseases, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=RSV kn-keyword=RSV en-keyword=Surveillance kn-keyword=Surveillance en-keyword=Google Trends kn-keyword=Google Trends en-keyword=Epidemiology kn-keyword=Epidemiology END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=11 article-no= start-page=2095 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cholera Rapid Diagnostic Tests for the Detection of Vibrio cholerae O1: An Updated Meta-Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The rapid diagnosis of cholera contributes to adequate outbreak management. This meta-analysis assesses the diagnostic accuracy of cholera rapid tests (RDTs) to detect Vibrio cholerae O1. Methods: Systematic review and meta-analysis. We searched four databases (Medline, EMBASE, Google Scholar, and Web of Science up to 8 September 2021) for studies that evaluated cholera RDTs for the detection of V. cholerae O1 compared with either stool culture or polymerase chain reaction (PCR). We assessed the studies' quality using the QUADAS-2 criteria. In addition, in this update, GRADE approach was used to rate the overall certainty of the evidence. We performed a bivariate random-effects meta-analysis to calculate the pooled sensitivity and specificity of cholera RDTs. Results: Overall, 20 studies were included in this meta-analysis. Studies were from Africa (n = 11), Asia (n = 7), and America (Haiti; n = 2). They evaluated eight RDTs (Crystal VC-O1, Crystal VC, Cholkit, Institut Pasteur cholera dipstick, SD Bioline, Artron, Cholera Smart O1, and Smart II Cholera O1). Using direct specimen testing, sensitivity and specificity of RDTs were 90% (95% CI, 86 to 93) and 86% (95% CI, 81 to 90), respectively. Cholera Sensitivity was higher in studies conducted in Africa [92% (95% CI, 89 to 94)] compared with Asia [82% (95% CI, 77 to 87)]. However, specificity [83% (95% CI, 71 to 91)] was lower in Africa compared with Asia [90% (95% CI, 84 to 94)]. GRADE quality of evidence was estimated as moderate. Conclusions: Against culture or PCR, current cholera RDTs have moderate sensitivity and specificity for detecting Vibrio cholerae O1. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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 Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=rapid test kn-keyword=rapid test en-keyword=cholera kn-keyword=cholera en-keyword=Vibrio cholera O1 kn-keyword=Vibrio cholera O1 en-keyword=sensitivity kn-keyword=sensitivity en-keyword=specificity kn-keyword=specificity en-keyword=accuracy kn-keyword=accuracy en-keyword=update kn-keyword=update END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=913619 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220629 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mycovirus Hunting Revealed the Presence of Diverse Viruses in a Single Isolate of the Phytopathogenic Fungus Diplodia seriata From Pakistan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diplodia seriata in the family Botryosphaeriaceae is a cosmopolitan phytopathogenic fungus and is responsible for causing cankers, fruit rot and leaf spots on economically important plants. In this study, we characterized the virome of a single Pakistani strain (L3) of D. seriata. Several viral-like contig sequences were obtained via a previously conducted next-generation sequencing analysis. Multiple infection of the L3 strain by eight RNA mycoviruses was confirmed through RT-PCR using total RNA samples extracted from this strain; the entire genomes were determined via Sanger sequencing of RT-PCR and RACE clones. A BLAST search and phylogenetic analyses indicated that these eight mycoviruses belong to seven different viral families. Four identified mycoviruses belong to double-stranded RNA viral families, including Polymycoviridae, Chrysoviridae, Totiviridae and Partitiviridae, and the remaining four identified mycoviruses belong to single-stranded RNA viral families, i.e., Botourmiaviridae, and two previously proposed families "Ambiguiviridae" and "Splipalmiviridae". Of the eight, five mycoviruses appear to represent new virus species. A morphological comparison of L3 and partially cured strain L3ht1 suggested that one or more of the three viruses belonging to Polymycoviridae, "Splipalmiviridae" and "Ambiguiviridae" are involved in the irregular colony phenotype of L3. To our knowledge, this is the first report of diverse virome characterization from D. seriata. en-copyright= kn-copyright= en-aut-name=KhanHaris Ahmed en-aut-sei=Khan en-aut-mei=Haris Ahmed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BhattiMuhammad Faraz en-aut-sei=Bhatti en-aut-mei=Muhammad Faraz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Atta-ur-Rahman School of Applied Biosciences (ASAB), National University of Sciences and Technology (NUST) kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Atta-ur-Rahman School of Applied Biosciences (ASAB), National University of Sciences and Technology (NUST) kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=phytopathogenic fungi kn-keyword=phytopathogenic fungi en-keyword=mycovirome kn-keyword=mycovirome en-keyword=next-generation sequencing kn-keyword=next-generation sequencing en-keyword=Diplodia seriata kn-keyword=Diplodia seriata en-keyword=Botryosphaeriaceae kn-keyword=Botryosphaeriaceae en-keyword=ssRNA virus kn-keyword=ssRNA virus en-keyword=dsRNA virus kn-keyword=dsRNA virus en-keyword=virus kn-keyword=virus en-keyword=virus interaction kn-keyword=virus interaction END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=12 article-no= start-page=7141 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Kinetics of Serological Antibodies against Vibrio cholerae Following a Clinical Cholera Case: A Systematic Review and Meta-Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Approximately 2.9 million people worldwide suffer from cholera each year, many of whom are destitute. However, understanding of immunity against cholera is still limited. Several studies have reported the duration of antibodies following cholera; however, systematic reviews including a quantitative synthesis are lacking. Objective: To meta-analyze cohort studies that have evaluated vibriocidal, cholera toxin B subunit (CTB), and lipopolysaccharide (LPS) antibody levels following a clinical cholera case. Methods: Design: Systematic review and meta-analysis. We searched PubMed and Web of science for studies assessing antibodies against Vibrio cholerae in cohorts of patients with clinical cholera. Two authors independently extracted data and assessed the quality of included studies. Random effects models were used to pool antibody titers in adults and older children (aged >= 6 years). In sensitivity analysis, studies reporting data on young children (2-5 years) were included. Results: Nine studies met our inclusion criteria for systematic review and seven for meta-analysis. The pooled mean of vibriocidal antibody titers in adults and older children (aged >= 6 years) was 123 on day 2 post-symptom onset, which sharply increased on day 7 (pooled mean = 6956) and gradually waned to 2247 on day 30, 578 on day 90, and 177 on day 360. Anti-CTB IgA antibodies also peaked on day 7 (pooled mean = 49), followed by a rapid decrease on day 30 (pooled mean = 21), and further declined on day 90 (pooled mean = 10), after which it plateaued from day 180 (pooled mean = 8) to 360 (pooled mean = 6). Similarly, anti-CTB IgG antibodies peaked in early convalescence between days 7 (pooled mean = 65) and 30 (pooled mean = 69), then gradually waned on days 90 (pooled mean = 42) and 180 (pooled mean = 30) and returned to baseline on day 360 (pooled mean = 24). Anti-LPS IgA antibodies peaked on day 7 (pooled mean = 124), gradually declined on day 30 (pooled mean = 44), which persisted until day 360 (pooled mean = 10). Anti LPS IgG antibodies peaked on day 7 (pooled mean = 94). Thereafter, they decreased on day 30 (pooled mean = 85), and dropped further on days 90 (pooled mean = 51) and 180 (pooled mean = 47), and returned to baseline on day 360 (pooled mean = 32). Sensitivity analysis including data from young children (aged 2-5 years) showed very similar findings as in the primary analysis. Conclusions: This study confirms that serological antibody (vibriocidal, CTB, and LPS) titers return to baseline levels within 1 year following clinical cholera, i.e., before the protective immunity against subsequent cholera wanes. However, this decay should not be interpreted as waning immunity because immunity conferred by cholera against subsequent disease lasts 3-10 years. Our study provides evidence for surveillance strategies and future research on vaccines and also demonstrates the need for further studies to improve our understanding of immunity against cholera. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitraDebmalya en-aut-sei=Mitra en-aut-mei=Debmalya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cholera kn-keyword=cholera en-keyword=antibodies kn-keyword=antibodies en-keyword=vibriocidal kn-keyword=vibriocidal en-keyword=cholera toxin B kn-keyword=cholera toxin B en-keyword=lipopolysaccharide kn-keyword=lipopolysaccharide en-keyword=immunoglobulin kn-keyword=immunoglobulin en-keyword=immunity kn-keyword=immunity en-keyword=waning kn-keyword=waning END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue= article-no= start-page=124 end-page=136 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Managements of sleep bruxism in adult: A systematic review en-subtitle= kn-subtitle= en-abstract= kn-abstract=This systematic review aimed to update the management of sleep bruxism (SB) in adults, as diagnosed using polysomnography (PSG) and/or electromyography (EMG). Management methods covered were oral appliance therapy (OAT) with stabilization splints, cognitive-behavioral therapy (CBT), biofeedback therapy (BFT), and pharmacological therapy. A comprehensive search was conducted on MEDLINE, Cochrane Library, and Web of Science up to October 1st, 2021. Reference list searches and hand searches were also performed by an external organization. Two reviewers for each therapy independently performed article selection, data extraction, and risk of bias assessment. The reviewers resolved any disagreements concerning the assortment of the articles by discussion. Finally, 11, 3, 14, and 22 articles were selected for each therapy. The results suggested that OAT tended to reduce the number of SB events, although there was no significant difference compared to other types of splints, that the potential benefits of CBT were not well supported, and that BFT, rabeprazole, clonazepam, clonidine, and botulinum toxin type A injection showed significant reductions in specific SB parameters, although several side effects were reported. It can be concluded that more methodologically rigorous randomized large-sample long-term follow-up clinical trials are needed to clarify the efficacy and safety of management for SB. en-copyright= kn-copyright= en-aut-name=MinakuchiHajime en-aut-sei=Minakuchi en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujisawaMasanori en-aut-sei=Fujisawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeYuka en-aut-sei=Abe en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IidaTakashi en-aut-sei=Iida en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkiKyosuke en-aut-sei=Oki en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkuraKazuo en-aut-sei=Okura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanabeNorimasa en-aut-sei=Tanabe en-aut-mei=Norimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishiyamaAkira en-aut-sei=Nishiyama en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Division of Fixed Prosthodontics, Department of Restorative & Biomaterials Sciences, Meikai University School of Dentistry kn-affil= affil-num=3 en-affil=Department of Prosthodontics, School of Dentistry, Showa University kn-affil= affil-num=4 en-affil=Department of Oral Function and Fixed Prosthodontics, Nihon University School of Dentistry at Matsudo kn-affil= affil-num=5 en-affil=Section of Fixed Prosthodontics, Division of Oral Rehabilitation, Faculty of Dental Science, Kyushu University kn-affil= affil-num=6 en-affil=Department of Stomatognathic Function and Occlusal Reconstruction, Institute of Biomedical Sciences, Tokushima University Graduate School kn-affil= affil-num=7 en-affil=Department of Prosthodontics and Oral Implantology, School of Dentistry, Iwate Medical University kn-affil= affil-num=8 en-affil=General Dentistry, Comprehensive Patient Care, Oral Health Sciences, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University kn-affil= en-keyword=Sleep bruxism kn-keyword=Sleep bruxism en-keyword=Management kn-keyword=Management en-keyword=Systematic review kn-keyword=Systematic review en-keyword=Oral appliances kn-keyword=Oral appliances en-keyword=Biofeedback therapy kn-keyword=Biofeedback therapy en-keyword=Cognitive-behavioral therapy kn-keyword=Cognitive-behavioral therapy en-keyword=Pharmacological therapy kn-keyword=Pharmacological therapy END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=2534 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Breast Cancer Awareness Month on Public Interest in the United States between 2012 and 2021: A Google Trends Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Simple Summary In this study, we quantified public awareness regarding breast cancer associated with Breast Cancer Awareness Month (BCAM) in October using Google Trends data and a joinpoint regression analysis. We analyzed the impact of BCAM, Lung Cancer Awareness Month (LCAM), and Prostate Cancer Awareness Month (PCAM) on public awareness of the top three most common cancers in the U.S. from 2012 to 2021 using the relative search volume of Google Trends. The results imply that BCAM has successfully improved the public awareness of breast cancer in the U.S., while LCAM and PCAM had no impact on the awareness of lung and prostate cancers. BCAM could serve as a good example for organizations working on health observances or awareness campaigns. Breast Cancer Awareness Month (BCAM) has a long history of over 30 years, established in 1985 to occur every October, and the National Breast Cancer Foundation now leads the operation. There have been no studies to evaluate the impact of the BCAM on public awareness of breast cancer. We analyzed the impact of BCAM on public awareness of breast cancer in the U.S. from 2012 to 2021 using the relative search volume (RSV) of Google Trends as a surrogate. We also analyzed the impact of Lung Cancer Awareness Month (LCAM) and Prostate Cancer Awareness Month (PCAM) on public awareness of lung and prostate cancer, respectively, to see differences in their effectiveness among the health observances for the top three most common cancers in the U.S. We performed a joinpoint regression analysis to identify statistically significant time points of a change in trend. There were joinpoints around BCAM for "Breast cancer" every year from 2012 to 2021, with a significant increase in the weekly RSVs from 21.9% to 46.7%. Except for 2013 and 2015 for "Lung cancer", when significant increases in the RSV at 1.8% and 1.2% per week were observed around LCAM, no joinpoints were noted around LCAM or PCAM. These results imply that BCAM has successfully improved the public awareness of breast cancer in the U.S. compared to other representative health observances, likely due to the effective involvement of non-medical industries, influencers affected by breast cancer, and an awareness symbol. en-copyright= kn-copyright= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AcobaJared D. en-aut-sei=Acoba en-aut-mei=Jared D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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 Medicine, John A.

However, a systematic review on the drivers responsible for these outbreaks has yet to be published. Here, we systematically review the published literature on cholera outbreaks in India between 2011 and 2020. We searched studies in English in three databases (MEDLINE, EMBASE, and Web of Science) and the Integrated Disease Surveillance Program that tracks cholera outbreaks throughout India. Two authors independently extracted data and assessed the quality of the included studies. Quantitative data on the modes of transmission reviewed in this study were assessed for any change over time between 2011-2015 and 2016-2020. Our search retrieved 10823 records initially, out of which 81 full-text studies were assessed for eligibility. Among these 81 studies, 20 were eligible for inclusion in this review. There were 565 reported outbreaks between 2011 and 2020 that led to 45,759 cases and 263 deaths. Outbreaks occurred throughout the year; however, they exploded with monsoons (June through September). In Tamil Nadu, a typical peak of cholera outbreaks was observed from December to January. Seventy-two percent (33,089/45,759) of outbreak-related cases were reported in five states, namely Maharashtra, West Bengal, Punjab, Karnataka, and Madhya Pradesh. Analysis of these outbreaks highlighted the main drivers of cholera including contaminated drinking water and food, inadequate sanitation and hygiene (including open defecation), and direct contact between households. The comparison between 2011-2015 and 2016-2020 showed a decreasing trend in the outbreaks that arose due to damaged water pipelines. Many Indians still struggle with open defecation, sanitation, and clean water access. These issues should be addressed critically. In addition, it is essential to interrupt cholera short-cycle transmission (mediated by households, stored drinking water and foodstuffs) during an outbreak. As cholera is associated with deprivation, socio-economic development is the only long-term solution. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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 Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cholera kn-keyword=cholera en-keyword=outbreak kn-keyword=outbreak en-keyword=water supply kn-keyword=water supply en-keyword=open defecation kn-keyword=open defecation en-keyword=sewage kn-keyword=sewage en-keyword=household kn-keyword=household en-keyword=food kn-keyword=food en-keyword=close contact kn-keyword=close contact en-keyword=behavioral changes kn-keyword=behavioral changes en-keyword=India kn-keyword=India END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=3 article-no= start-page=21 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220520 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Political, Economic, and Social Changes since the System Transformation Period in Poland: Doctrinal Trends of the Catholic Church and the Rise of Populism kn-title=ポーランドにおける体制転換以降の政治・経済・社会的変動 －カトリック教会の動向とポピュリズム政治の台頭を中心に－ en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper describes the doctrinal trends of the Catholic Church and the rise of populist politics by analyzing the political, economic, and social changes that have occurred since the system transformation period.
In 1989, Poland became the first socialist country to establish a non-communist government and led the system transformations in Eastern European countries. Politically, Poland has broken the communist dictatorship and introduced political pluralism, economically she has promoted market liberalization, and socially she has achieved democratization and cultural pluralism. However, politicians, while superficially advocating political pluralism, often engaged in a battle of mutual accusations through “lustration,” which refers to policies that limit the participation of former communists, especially informants of the communist secret police, resulting in political chaos. In recent years, under the “Law and Justice” regime, Catholic traditions and conservative national and family values have been honored as values that must be upheld by Poles, while EU skepticism has been propagated, anti-immigrant sentiments have been fanned, and the clampdown on LGBT people has been tightened. Conflicts with the EU have also intensified, including political intervention in the judiciary and the supremacy of domestic law over EU law. Put simply, Law and Justice, while claiming to reintroduce pluralism into a Polish polity dominated by the monolithic technocratic liberalism that was dominant in the early years of the transition, has in fact empowered social groups that felt excluded from the post-1989 reforms to create a more exclusive monism.
Thus, while Poland received international attention as a country that led the way in democratization among the former Eastern European countries, even today pluralism has not taken stable root. In Chapter 1, the political and economic situation and changes of doctrine of the Church during the transition period will be analyzed. In Chapter 2, the political changes during the EU accession period and the church’s search for its position will mentioned. The chapter ３ will analyze the rise of populism after 2015 and its relationship to the Catholic Church. en-copyright= kn-copyright= en-aut-name=IemotoHiroichi en-aut-sei=Iemoto en-aut-mei=Hiroichi kn-aut-name=家本博一 kn-aut-sei=家本 kn-aut-mei=博一 aut-affil-num=1 ORCID= en-aut-name=TaguchiMasahiro en-aut-sei=Taguchi en-aut-mei=Masahiro kn-aut-name=田口雅弘 kn-aut-sei=田口 kn-aut-mei=雅弘 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=名古屋学院大学名誉教授 affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=6088 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of osteoporosis using ensemble deep learning model with panoramic radiographs and clinical covariates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osteoporosis is becoming a global health issue due to increased life expectancy. However, it is difficult to detect in its early stages owing to a lack of discernible symptoms. Hence, screening for osteoporosis with widely used dental panoramic radiographs would be very cost-effective and useful. In this study, we investigate the use of deep learning to classify osteoporosis from dental panoramic radiographs. In addition, the effect of adding clinical covariate data to the radiographic images on the identification performance was assessed. For objective labeling, a dataset containing 778 images was collected from patients who underwent both skeletal-bone-mineral density measurement and dental panoramic radiography at a single general hospital between 2014 and 2020. Osteoporosis was assessed from the dental panoramic radiographs using convolutional neural network (CNN) models, including EfficientNet-b0, -b3, and -b7 and ResNet-18, -50, and -152. An ensemble model was also constructed with clinical covariates added to each CNN. The ensemble model exhibited improved performance on all metrics for all CNNs, especially accuracy and AUC. The results show that deep learning using CNN can accurately classify osteoporosis from dental panoramic radiographs. Furthermore, it was shown that the accuracy can be improved using an ensemble model with patient covariates. en-copyright= kn-copyright= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimuraAi en-aut-sei=Fujimura en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaguchiAkira en-aut-sei=Taguchi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraAkira en-aut-sei=Kitamura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoRyosuke en-aut-sei=Goto en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FurukiYoshihiko en-aut-sei=Furuki en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, School of Dentistry, Matsumoto Dental University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Search Space Inc. kn-affil= affil-num=6 en-affil=Search Space Inc. kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=8 article-no= start-page=4714 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220413 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Misconceptions and Rumors about Ebola Virus Disease in Sub-Saharan Africa: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=We sought to summarize knowledge, misconceptions, beliefs, and practices about Ebola that might impede the control of Ebola outbreaks in Africa. We searched Medline, EMBASE, CINAHL, and Google Scholar (through May 2019) for publications reporting on knowledge, attitudes, and practices (KAP) related to Ebola in Africa. In total, 14 of 433 articles were included. Knowledge was evaluated in all 14 articles, and they all highlighted that there are misconceptions and risk behaviors during an Ebola outbreak. Some communities believed that Ebola spreads through the air, mosquito bites, malice from foreign doctors, witchcraft, and houseflies. Because patients believe that Ebola was caused by witchcraft, they sought help from traditional healers. Some people believed that Ebola could be prevented by bathing with salt or hot water. Burial practices where people touch Ebola-infected corpses were common, especially among Muslims. Discriminatory attitudes towards Ebola survivors or their families were also prevalent. Some Ebola survivors were not accepted back in their communities; the possibility of being ostracized from their neighborhoods was high and Ebola survivors had to lead a difficult social life. Most communities affected by Ebola need more comprehensive knowledge on Ebola. Efforts are needed to address misconceptions and risk behaviors surrounding Ebola for future outbreak preparedness in Africa. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NtontoloNgangu Patrick en-aut-sei=Ntontolo en-aut-mei=Ngangu Patrick kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NgatuNlandu Roger en-aut-sei=Ngatu en-aut-mei=Nlandu Roger kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhatiwadaJanuka en-aut-sei=Khatiwada en-aut-mei=Januka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiTomoko en-aut-sei=Suzuki en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaKoji en-aut-sei=Wada en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkedaShunya en-aut-sei=Ikeda en-aut-mei=Shunya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Family Medicine and Primary Health, Protestant University of Congo kn-affil= affil-num=3 en-affil=Department of Public Health, Kagawa University Faculty of Medicine kn-affil= affil-num=4 en-affil=Social Work Institute kn-affil= affil-num=5 en-affil=Department of Public Health, School of Medicine, International University of Health and Welfare kn-affil= affil-num=6 en-affil=Department of Public Health, School of Medicine, International University of Health and Welfare kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Public Health, School of Medicine, International University of Health and Welfare kn-affil= affil-num=9 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Ebola kn-keyword=Ebola en-keyword=knowledge kn-keyword=knowledge en-keyword=attitudes kn-keyword=attitudes en-keyword=practices kn-keyword=practices en-keyword=beliefs kn-keyword=beliefs en-keyword=misperceptions kn-keyword=misperceptions en-keyword=rumors kn-keyword=rumors en-keyword=sub-Saharan Africa kn-keyword=sub-Saharan Africa END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=7 article-no= start-page=e28872 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Silica-associated systemic lupus erythematosus with lupus nephritis and lupus pneumonitis A case report and a systematic review of the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Several epidemiological studies have shown that silica exposure triggers the onset of systemic lupus erythematosus (SLE); however, the clinical characteristics of silica-associated SLE have not been well studied. Patient concerns A 67-year-old man with silicosis visited a primary hospital because of a fever and cough. His respiratory condition worsened, regardless of antibiotic medication, and he was referred to our hospital. Diagnosis The patient showed leukopenia, lymphopenia, serum creatinine elevation with proteinuria and hematuria, decreased serum C3 level, and was positive for anti-double stranded DNA antibody, anti-nuclear antibody, and direct Coombs test. He was diagnosed with SLE. Renal biopsy was performed, and the patient was diagnosed with lupus nephritis (class IV-G(A/C) + V defined by the International Society of Nephrology/Renal Pathology Society classification). Computed tomography revealed acute interstitial pneumonitis, bronchoalveolar lavage fluid showed elevation of the lymphocyte fraction, and he was diagnosed with lupus pneumonitis. Interventions Prednisolone (50 mg/day) with intravenous cyclophosphamide (500 mg/body) were initiated. Outcomes The patient showed a favorable response to these therapies. He was discharged from our hospital and received outpatient care with prednisolone slowly tapered off. He had cytomegalovirus and herpes zoster virus infections during treatment, which healed with antiviral therapy. Review: We searched for the literature on sSLE, and selected 11 case reports and 2 population-based studies. The prevalence of SLE manifestations in sSLE patients were comparative to that of general SLE, particularly that of elderly-onset SLE. Our renal biopsy report and previous reports indicate that lupus nephritis of sSLE patients show as various histological patterns as those of general SLE patients. Among the twenty sSLE patients reported in the case articles, three patients developed lupus pneumonitis and two of them died of it. Moreover, two patients died of bacterial pneumonia, one developed aspergillus abscesses, one got pulmonary tuberculosis, and one developed lung cancer. Conclusion Close attention is needed, particularly for respiratory system events and infectious diseases, when treating patients with silica-associated SLE using immunosuppressive therapies.

kn-abstract=Small bowel metastasis from renal cell carcinoma (RCC) is rare, and its clinicopathological characteristics are unclear; thus, we revisited the concept of this tumor and reviewed its diagnostic and treatment modalities. We filtered MEDLINE searches of articles published in English between 1950 and 2019, and identified 100 patients who had undergone treatment, including 1 patient from our clinic. We extracted patient characteristics, treatment, and prognostic data, resulting in clinicopathological data on 100 patients (83 men, 17 women). Mean age was 63 years (range, 16-86 years). Tumor sites were duodenum, jejunum, ileum, and multiple sites in 30, 37, 25, and 7 patients, respectively. The 1-, 3-, and 5-year overall survival rates after diagnosis were 53.0%, 36.0%, and 36.0%. Curative resection patients showed 62.1% 5-year survival after surgery, vs. 27.5% in noncurative surgical management cases. Good prognoses can be expected if these tumors are identified early for complete removal. Surgery is the only curative option. To determine the best management strategy and improve prognostic accuracy, we continue to collect and analyze epidemiological and pathological data. Although this condition is rare, surgery should be considered if curative resection is expected. Prognosis after curative resection is not poor, but recurrence is not unlikely. en-copyright= kn-copyright= en-aut-name=KimuraJiro en-aut-sei=Kimura en-aut-mei=Jiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuiKenta en-aut-sei=Sui en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TabuchiMotoyasu en-aut-sei=Tabuchi en-aut-mei=Motoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HataYasuhiro en-aut-sei=Hata en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IiyamaTatsuo en-aut-sei=Iiyama en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OnoNoriaki en-aut-sei=Ono en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, National Center for Global Health and Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, National Center for Global Health and Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, National Center for Global Health and Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, National Center for Global Health and Medicine kn-affil= affil-num=5 en-affil=Department of Diagnostic Pathology, National Center for Global Health and Medicine kn-affil= affil-num=6 en-affil=Department of Radiology, National Center for Global Health and Medicine kn-affil= affil-num=7 en-affil=Department of Biostatistics, National Center for Global Health and Medicine kn-affil= affil-num=8 en-affil=Department of Urology, Kochi Health Sciences Center kn-affil= en-keyword=renal cell carcinoma kn-keyword=renal cell carcinoma en-keyword=small bowel metastasis kn-keyword=small bowel metastasis en-keyword=intestine kn-keyword=intestine en-keyword=tumor kn-keyword=tumor END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=2 article-no= start-page=87 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Confirmation of efficacy, elucidation of mechanism, and new search for indications of radon therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Indications of radon therapy include various diseases related to respiratory, painful, digestive, chronic degenerative, senile, etc. derived from reactive oxygen species, but most are based on empirical prescriptions. For this reason, we have evaluated the relation between the biological response caused by radon and the tissue/organ absorbed dose more quantitatively, and have promoted the elucidation of mechanisms related to the indication and searching newly. As a result, as a mechanism, a series of moderate physiological stimulative effects accompanying a small amount of oxidative stress by radon inhalation are being elucidated. That is, hyperfunction of anti-oxidation/immune regulation/damage repair, promotion of anti-inflammation/circulating metabolism/hormone secretion, induction of apoptosis/heat shock protein, etc. Also, new indications include inflammatory/neuropathic pain, hepatic/renal injury, colitis, type 1 diabetes, complication kidney injury, hyperuricemia, transient cerebral ischemia, and inflammatory edema. Furthermore, we examined the combined antioxidant effect of radon inhalation and antioxidants or therapeutic agents. As a result, it was clear that any combination treatment could enhance the suppression effect of disease. It can be expected that radon therapy can be used effectively by applying it in addition to usual treatment, since reduction in its dosage can also be expected by concomitant use for drugs with strong side effects. en-copyright= kn-copyright= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Health Sciences, Institute of Academic and Research, Okayama University kn-affil= affil-num=2 en-affil=Health Sciences, Institute of Academic and Research, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=307 cd-vols= no-issue=2 article-no= start-page=198606 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new tetra-segmented splipalmivirus with divided RdRP domains from Cryphonectria naterciae, a fungus found on chestnut and cork oak trees in Europe en-subtitle= kn-subtitle= en-abstract= kn-abstract=Positive-sense (+), single-stranded (ss) RNA viruses with divided RNA-dependent RNA polymerase (RdRP) domains have been reported from diverse filamentous ascomycetes since 2020. These viruses are termed splipalmiviruses or polynarnaviruses and have been characterized largely at the sequence level, but ill-defined biologically. Cryphonectria naterciae, from which only one virus has been reported, is an ascomycetous fungus potentially plant-pathogenic to chestnut and oak trees. We molecularly characterized multiple viruses in a single Portuguese isolate (C0614) of C. naterciae, taking a metatranscriptomic and conventional double-stranded RNA approach. Among them are a novel splipalmivirus (Cryphonectria naterciae splipalmivirus 1, CnSpV1) and a novel fusagravirus (Cryphonectria naterciae fusagravirus 1, CnFGV1). This study focused on the former virus. CnSpV1 has a tetra-segmented, (+)ssRNA genome (RNA1 to RNA4). As observed for other splipalmiviruses reported in 2020 and 2021, the RdRP domain is separately encoded by RNA1 (motifs F, A and B) and RNA2 (motifs C and D). A hypothetical protein encoded by the 5′-proximal open reading frame of RNA3 shows similarity to a counterpart conserved in some splipalmiviruses. The other RNA3-encoded protein and RNA4-encoded protein show no similarity with known proteins in a blastp search. The tetra-segment nature was confirmed by the conserved terminal sequences of the four CnSpV1 segments (RNA1 to RNA4) and their 100% coexistence in over 100 single conidial isolates tested. The experimental introduction of CnSpV1 along with CnFGV1 into a virus free strain C0754 of C. naterciae vegetatively incompatible with C0614 resulted in no phenotypic alteration, suggesting asymptomatic infection. The protoplast fusion assay indicates a considerably narrow host range of CnSpV1, restricted to the species C. naterciae and C. carpinicola. This study contributes to better understanding of the molecular and biological properties of this unique group of viruses. en-copyright= kn-copyright= en-aut-name=SatoYukiyo en-aut-sei=Sato en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShahiSabitree en-aut-sei=Shahi en-aut-mei=Sabitree kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CornejoCarolina en-aut-sei=Cornejo en-aut-mei=Carolina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RiglingDaniel en-aut-sei=Rigling en-aut-mei=Daniel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Swiss Federal Research Institute WSL, Forest Health & Biotic Interactions kn-affil= affil-num=6 en-affil=Swiss Federal Research Institute WSL, Forest Health & Biotic Interactions kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Splipalmivirus kn-keyword=Splipalmivirus en-keyword=Capsidless kn-keyword=Capsidless en-keyword=RNA virus kn-keyword=RNA virus en-keyword=Cryphonectria naterciae kn-keyword=Cryphonectria naterciae en-keyword=Narnavirus kn-keyword=Narnavirus en-keyword=Fungal virus kn-keyword=Fungal virus en-keyword=Mycovirus kn-keyword=Mycovirus END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=5 article-no= start-page=1155 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Procalcitonin to Predict Severity of Acute Cholangitis and Need for Urgent Biliary Decompression: Systematic Scoping Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum procalcitonin (PCT) has been reported as a potential biomarker to predict the severity of acute cholangitis (AC) or the need for urgent biliary decompression. This study aimed to identify and summarize the existing research about serum PCT and the severity of AC, and to find gaps towards which future studies can be targeted. Following the PRISMA extension for scoping reviews, MEDLINE, EMBASE, and Google Scholar were searched for all peer-reviewed articles with relevant keywords including "cholangitis" and "procalcitonin" from their inception to 13 July 2021. We identified six studies. All the studies employed a case-control design and aimed to evaluate the usefulness of serum PCT to predict the severity of AC with key identified outcomes. While the potential cut-off values of serum PCT for severe AC ranged from 1.8-3.1 ng/mL, studies used different severity criteria and the definition of urgent biliary decompression. No studies proposed cut-off PCT values for the need for urgent biliary decompression. This scoping review identified the current level of evidence regarding the usefulness of serum PCT in assessing the severity of AC. Further clinical research is warranted with a focus on standardized outcome measures employing prospective or experimental designs. en-copyright= kn-copyright= en-aut-name=SilangcruzKrixie en-aut-sei=Silangcruz en-aut-mei=Krixie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CzechTorrey en-aut-sei=Czech en-aut-mei=Torrey kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraNobuhiko en-aut-sei=Kimura en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YessJames en-aut-sei=Yess en-aut-mei=James kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Internal Medicine, University of Hawai’i 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 Internal Medicine, University of Hawai’i kn-affil= affil-num=4 en-affil=Department of Internal Medicine, University of Hawai’i kn-affil= affil-num=5 en-affil=Department of Internal Medicine, University of Hawai’i kn-affil= en-keyword=procalcitonin kn-keyword=procalcitonin en-keyword=acute cholangitis kn-keyword=acute cholangitis en-keyword=scoping review kn-keyword=scoping review en-keyword=systematic review kn-keyword=systematic review END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=136 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Support for Sexual Minority Students in Overseas Universities －Support Status Searched from American Universities Websites－ kn-title=海外の大学におけるセクシュアルマイノリティ学生支援 ーウェブサイトから分かるアメリカの大学の支援状況一 en-subtitle= kn-subtitle= en-abstract= kn-abstract=アメリカの大学におけるセクシュアルマイノリティ学生への支援状況について，State and territorial universities 623校を対象に、各大学のウェブサイトを参照して調査を行った。セクシュアルマイノリティ学生を専門にサポートするセンター・部署を持つ339校の「センター・部署の名称」「支援・活動内容」を調査したところ、名称で多く使用されている単語や、多くの大学で行われている支援・活動内容が明らかとなった。支援・活動内容は10のグループに分類され、「施設・設備」「カウンセリング・サポート」「LGBT関連」「相互支援」「啓発活動」「各種資料提供」「経済・服」「医療」「性関連」「その他」であった。これらの結果は今後の日本の大学における支援・活動の参考となるものであった。 en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=松井めぐみ kn-aut-sei=松井 kn-aut-mei=めぐみ aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= en-keyword=セクシュアルマイノリティ kn-keyword=セクシュアルマイノリティ en-keyword=大学 kn-keyword=大学 en-keyword=相談 kn-keyword=相談 en-keyword=支援 kn-keyword=支援 en-keyword=アメリカ kn-keyword=アメリカ END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue=2 article-no= start-page=141 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of the world hand hygiene and global handwashing days on public awareness between 2016 and 2020: Google trends analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Scientific evidence suggest that hand hygiene as one of the most effective measures to control infection. To promote good hand hygiene practices, the World Health Organization introduced May 5 as World Hand Hygiene Day (WHHD), and international stakeholders established Global Handwashing Day (GHD) on October 15. However, its contributions to raising public awareness of hand hygiene is unclear. Methods: This study evaluates the impact of the WHHD and GHD on the public awareness of hand hygiene in Japan, the United Kingdom, the United States, and worldwide from 2016 to 2020, using the relative search volume of "Hand hygiene" in Google Trends as a surrogate. To identify a statistically significant timepoint of a trend change, we performed Joinpoint regression analysis. Results: Upticks of the relative search volumes as well as joinpoints were noted worldwide around the WHHD and GHD from 2016 to 2019, but no joinpoints were identified around the WHHD and GHD in 2020. No such changes were observed in Japan, the United Kingdom, and the United States during these periods. Conclusions: While the WHHD was originally established to raise awareness of hand hygiene in healthcare facilities, our result suggests that the WHHD and GHD may not have effectively disseminated the importance of hand hygiene to the general public at a country level. Additional policy measures to advocate hand hygiene to the public are necessary to communicate its benefits. (c) 2021 Association for Professionals in Infection Control and Epidemiology, Inc.

A limited number of reports on mycoviruses from this fungus are available. Here, we report the characterization of a novel victorivirus, Neofusicoccum parvum victorivirus 3 (NpVV3). An agarose gel dsRNA profile of a Pakistani strain of N. parvum, NFN, showed a band of similar to 5 kbp that was not detectable in Japanese strains of N. parvum. Taking a high-throughput and Sanger sequencing approach, the complete genome sequence of NpVV3 was determined to be 5226 bp in length with two open reading frames (ORF1 and ORF2) that encode a capsid protein (CP) and an RNA-dependent RNA polymerase (RdRP). The RdRP appears to be translated by a stop/restart mechanism facilitated by the junction sequence AUGucUGA, as is found in some other victoriviruses. BLASTp searches showed that NpVV3 CP and RdRP share the highest amino acid sequence identity (80.5% and 72.4%, respectively) with the corresponding proteins of NpVV1 isolated from a French strain of N. parvum. However, NpVV3 was found to be different from NpVV1 in its terminal sequences and the stop/restart facilitator sequence. NpVV3 particles similar to 35 nm in diameter were partially purified and used to infect an antiviral-RNA-silencing-deficient strain (Delta cl2) of an experimental ascomycetous fungal host, Cryphonectria parasitica. NpVV3 showed symptomless infection in the new host strain. en-copyright= kn-copyright= en-aut-name=KhanHaris Ahmed en-aut-sei=Khan en-aut-mei=Haris Ahmed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoYukiyo en-aut-sei=Sato en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JamalAtif en-aut-sei=Jamal en-aut-mei=Atif kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BhattiMuhammad Faraz en-aut-sei=Bhatti en-aut-mei=Muhammad Faraz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Atta-ur-Rahman School of Applied Biosciences (ASAB), National University of Sciences and Technology (NUST) kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Crop Diseases Research Institute, National Agricultural Research Centre kn-affil= affil-num=5 en-affil=Atta-ur-Rahman School of Applied Biosciences (ASAB), National University of Sciences and Technology (NUST) kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue= article-no= start-page=106731 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acute acalculous cholecystitis caused by SARS-CoV-2 infection: A case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Emerging data indicate that gastrointestinal disorders, in addition to pulmonary dysfunction, are also hallmarks of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Case presentation: A 42-year-old man with maintenance hemodialysis developed high fever and dyspnea. He was positive for SARS-CoV-2 and was diagnosed with pneumonia. After treatment for SARS-CoV-2, his respiratory condition improved. However, he developed right upper quadrant pain with elevated inflammatory markers (white blood cells, 21,160/mu L; c-reactive protein, 163.9 mg/L) on the 13th day. Abdominal computed tomography revealed acute acalculous cholecystitis. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed together with antibiotic therapy, which resulted in improvement of symptoms. Laparoscopic cholecystectomy was performed 36 days after PTGBD.
Conclusion: We report a rare case of acute acalculous cholecystitis (AAC) following pneumonia caused by SARS-CoV-2 infection. We also conducted a literature search to characterize SARS-CoV-2-related cholecystitis. Infection with SARS-CoV-2 is an important trigger for AAC, and appropriate therapeutic alternatives should be cautiously selected according to individual cases. en-copyright= kn-copyright= en-aut-name=FutagamiHana en-aut-sei=Futagami en-aut-mei=Hana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoHiroki en-aut-sei=Sato en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Center for Graduate Medical Education, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= en-keyword=Acute acalculous cholecystitis kn-keyword=Acute acalculous cholecystitis en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 en-keyword=COVID-19 kn-keyword=COVID-19 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=2021 dt-pub=20211220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=日本の雑草 種子画像データベース kn-title=Naturalized plants in Japan : Seed-Image database en-subtitle= kn-subtitle= en-abstract=日本の雑草の種子画像を公開しています。帰化植物種子画像データベースと日本の雑草種子画像データベースを合併しました。 kn-abstract=Naturalized Plants in Japan Seed-Image database is an image database of naturalized alien plant seeds recorded in Japan.

At the five-year follow-up after treatment, the tooth was completely restored and fulfilling its function, with no signs or symptoms of any post-treatment flare-up. en-copyright= kn-copyright= en-aut-name=Zulema Rosalia Arias Martinez en-aut-sei=Zulema Rosalia Arias Martinez en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Jorge Luis Lopez Videla Montaño en-aut-sei=Jorge Luis Lopez Videla Montaño en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamashiroKeisuke en-aut-sei=Yamashiro en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pathophysiology - Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Sistema de Radiografías Odontologicas (SIRO) kn-affil= affil-num=3 en-affil=Department of Pathophysiology - Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathophysiology - Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathophysiology - Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathophysiology - Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=dental operating microscope kn-keyword=dental operating microscope en-keyword=lower first premolar kn-keyword=lower first premolar en-keyword=multiple canals kn-keyword=multiple canals en-keyword=ultrasonic endodontic tips kn-keyword=ultrasonic endodontic tips END start-ver=1.4 cd-journal=joma no-vol=177 cd-vols= no-issue= article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210826 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Visualization of “Language Sense” to be Fostered in Early Childhood and the Search for Learning Materials Nurturing Sharp Senses kn-title=幼児期に育てたい「言葉に対する感覚」の明確化と感覚の豊かさをもたらす教材の探求 en-subtitle= kn-subtitle= en-abstract= kn-abstract=本稿ではまず，2017 年に改訂（定）された幼稚園教育要領の領域「言葉」に焦点を当て，生涯発達の始点である幼児期に育む言葉の力の変更点とその重要性について整理した。続いて，新たに育成することが求められることとなった「言葉に対する感覚」及び言葉を豊かにすることについて，小学校以降の学習指導要領に用いられている「言語感覚」を検討の手立てとして詳解を試みた。その結果，幼児期に育てたい「言葉に対する感覚」としては，自分が表現する立場と受け取る（理解する）立場の双方で，「言葉の表現の適否」や「言葉のニュアンスを感じ取れる」感覚を育もうとしていることを見出した。最後に，「教職課程コアカリキュラム」に新設された「領域に関する専門的事項」の科目に関連して，「言葉に対する感覚を豊かにする実践」を歌の歌詞を教材とすることの意義と可能性について論述した。 en-copyright= kn-copyright= en-aut-name=KatayamaMika en-aut-sei=Katayama en-aut-mei=Mika kn-aut-name=片山美香 kn-aut-sei=片山 kn-aut-mei=美香 aut-affil-num=1 ORCID= en-aut-name=HayakawaRinko en-aut-sei=Hayakawa en-aut-mei=Rinko kn-aut-name=早川倫子 kn-aut-sei=早川 kn-aut-mei=倫子 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 en-keyword=幼児 kn-keyword=幼児 en-keyword=言葉に対する感覚 kn-keyword=言葉に対する感覚 en-keyword=言語感覚 kn-keyword=言語感覚 en-keyword=言語力の育成 kn-keyword=言語力の育成 en-keyword=歌詞 kn-keyword=歌詞 END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=715545 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of a Novel Quinvirus in the Family Betaflexiviridae That Infects Winter Wheat en-subtitle= kn-subtitle= en-abstract= kn-abstract=Yellow mosaic disease in winter wheat is usually attributed to the infection by bymoviruses or furoviruses; however, there is still limited information on whether other viral agents are also associated with this disease. To investigate the wheat viromes associated with yellow mosaic disease, we carried out de novo RNA sequencing (RNA-seq) analyses of symptomatic and asymptomatic wheat-leaf samples obtained from a field in Hokkaido, Japan, in 2018 and 2019. The analyses revealed the infection by a novel betaflexivirus, which tentatively named wheat virus Q (WVQ), together with wheat yellow mosaic virus (WYMV, a bymovirus) and northern cereal mosaic virus (a cytorhabdovirus). Basic local alignment search tool (BLAST) analyses showed that the WVQ strains (of which there are at least three) were related to the members of the genus Foveavirus in the subfamily Quinvirinae (family Betaflexiviridae). In the phylogenetic tree, they form a clade distant from that of the foveaviruses, suggesting that WVQ is a member of a novel genus in the Quinvirinae. Laboratory tests confirmed that WVQ, like WYMV, is potentially transmitted through the soil to wheat plants. WVQ was also found to infect rye plants grown in the same field. Moreover, WVQ-derived small interfering RNAs accumulated in the infected wheat plants, indicating that WVQ infection induces antiviral RNA silencing responses. Given its common coexistence with WYMV, the impact of WVQ infection on yellow mosaic disease in the field warrants detailed investigation. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaNaoto en-aut-sei=Yoshida en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamaKazuyuki en-aut-sei=Maruyama en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Agricultural Research Institute, HOKUREN Federation of Agricultural Cooperatives kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=8 en-affil=College of Plant Health and Medicine, Qingdao Agricultural University kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Betaflexiviridae kn-keyword=Betaflexiviridae en-keyword=quinvirus kn-keyword=quinvirus en-keyword=bymovirus kn-keyword=bymovirus en-keyword=yellow mosaic disease kn-keyword=yellow mosaic disease en-keyword=wheat kn-keyword=wheat en-keyword=virome kn-keyword=virome en-keyword=soil borne kn-keyword=soil borne en-keyword=variants kn-keyword=variants END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=20489448 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202011 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Method of Generating a Blacklist for Mobile Devices by Searching Malicious Websites en-subtitle= kn-subtitle= en-abstract= kn-abstract=As mobile devices have become more popular, malware and attacks directed at them have significantly increased. One of the methods to attack mobile devices is redirecting a user to unwanted websites by unwanted page transition. One of the countermeasures against such attacks is to generate a blacklist of URLs and hostnames, which can prevent access to malicious websites. To generate a blacklist, first, malicious websites are collected in the web space. Then, URLs and hostnames of the malicious websites are added to the blacklist. However, URLs of the malicious websites are typically changed frequently; thus, it is necessary to keep track of the malicious websites and update the blacklist in a timely manner. In this study, we proposed a method to generate blacklists for mobile devices by searching malicious websites. The method collects many HTML files from the web space using a crawler and searches for HTML files that are highly likely to be malicious using keywords extracted from the known malicious websites to discover the new ones. Thus, new malicious websites can be added to the blacklist in a timely manner. Using the proposed method, we discovered malicious websites that were not detected by Google Safe Browsing. Moreover, the blacklist generated using the method had a high detection rate for certain malicious websites. This paper reports the design process and the results of the evaluation of the new method. en-copyright= kn-copyright= en-aut-name=IshiharaTakashi en-aut-sei=Ishihara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoMasaya en-aut-sei=Sato en-aut-mei=Masaya 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 Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Malicious Websites kn-keyword=Malicious Websites en-keyword=Blacklist kn-keyword=Blacklist en-keyword=Web-based Attack kn-keyword=Web-based Attack en-keyword=Android kn-keyword=Android END start-ver=1.4 cd-journal=joma no-vol=2021 cd-vols= no-issue= article-no= start-page=8883946 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210806 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Accuracy of Deep Learning Algorithms for the Diagnosis of Retinopathy of Prematurity by Fundus Images: A Systematic Review and Meta-Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Retinopathy of prematurity (ROP) occurs in preterm infants and may contribute to blindness. Deep learning (DL) models have been used for ophthalmologic diagnoses. We performed a systematic review and meta-analysis of published evidence to summarize and evaluate the diagnostic accuracy of DL algorithms for ROP by fundus images.
Methods. We searched PubMed, EMBASE, Web of Science, and Institute of Electrical and Electronics Engineers Xplore Digital Library on June 13, 2021, for studies using a DL algorithm to distinguish individuals with ROP of different grades, which provided accuracy measurements. ,e pooled sensitivity and specificity values and the area under the curve (AUC) of summary receiver operating characteristics curves (SROC) summarized overall test performance. ,e performances in validation and test datasets were assessed together and separately. Subgroup analyses were conducted between the definition and grades of ROP. ,reshold and nonthreshold effects were tested to assess biases and evaluate accuracy factors associated with DL models.
Results. Nine studies with fifteen classifiers were included in our meta-analysis. A total of 521,586 objects were applied to DL models. For combined validation and test datasets in each study, the pooled sensitivity and specificity were 0.953 (95% confidence intervals (CI): 0.946–0.959) and 0.975 (0.973–0.977), respectively, and the AUC was 0.984 (0.978–0.989). For the validation dataset and test dataset, the AUC was 0.977 (0.968–0.986) and 0.987 (0.982–0.992), respectively. In the subgroup analysis of ROP vs. normal and differentiation of two ROP grades, the AUC was 0.990 (0.944–0.994) and 0.982 (0.964–0.999), respectively.
Conclusions. Our study shows that DL models can play an essential role in detecting and grading ROP with high sensitivity, specificity, and repeatability. ,e application of a DL-based automated system may improve ROP screening and diagnosis in the future. en-copyright= kn-copyright= en-aut-name=ZhangJingjing en-aut-sei=Zhang en-aut-mei=Jingjing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuYangyang en-aut-sei=Liu en-aut-mei=Yangyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Regenerative and Reconstructive Medicine (Ophthalmology), Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital, Okayama University kn-affil= affil-num=4 en-affil=Department of Regenerative and Reconstructive Medicine (Ophthalmology), Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=7 article-no= start-page=467 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Serodiagnosis and Bacterial Genome of Helicobacter pylori Infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=The infection caused by Helicobacter pylori is associated with several diseases, including gastric cancer. Several methods for the diagnosis of H. pylori infection exist, including endoscopy, the urea breath test, and the fecal antigen test, which is the serum antibody titer test that is often used since it is a simple and highly sensitive test. In this context, this study aims to find the association between different antibody reactivities and the organization of bacterial genomes. Next-generation sequences were performed to determine the genome sequences of four strains of antigens with different reactivity. The search was performed on the common genes, with the homology analysis conducted using a genome ring and dot plot analysis. The two antigens of the highly reactive strains showed a high gene homology, and Western blots for CagA and VacA also showed high expression levels of proteins. In the poorly responsive antigen strains, it was found that the inversion occurred around the vacA gene in the genome. The structure of bacterial genomes might contribute to the poor reactivity exhibited by the antibodies of patients. In the future, an accurate serodiagnosis could be performed by using a strain with few gene mutations of the antigen used for the antibody titer test of H. pylori. en-copyright= kn-copyright= en-aut-name=IchiharaAina en-aut-sei=Ichihara en-aut-mei=Aina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OjimaHinako en-aut-sei=Ojima en-aut-mei=Hinako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeSusumu en-aut-sei=Take en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeAkari en-aut-sei=Watanabe en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YokotaKenji en-aut-sei=Yokota en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Bacteriology, Academic Field of Health Science Okayama University kn-affil= affil-num=2 en-affil=Department of Bacteriology, Academic Field of Health Science Okayama University kn-affil= affil-num=3 en-affil=Department of Bacteriology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Bacteriology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Health Care and Rehabilitation, Institute of Biomedical Sciences, Tokushima University Graduate School kn-affil= affil-num=8 en-affil=Department of Bacteriology, Academic Field of Health Science Okayama University kn-affil= en-keyword=antibody kn-keyword=antibody en-keyword=VacA kn-keyword=VacA en-keyword=CagA kn-keyword=CagA en-keyword=genome kn-keyword=genome END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=111 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202178 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effective highlighting modes of graphical user interfaces in visual information search en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study discusses the preferred highlighting mode for graphical user interface (GUI) design.

The experimental factors were the type of highlighting (color, bold, or color and bold), the target highlighting (highlighted or not highlighted), and the number of elements on GUI (few or many). The participants had to search for a predetermined target on the screen. The evaluation measures were the reaction time and percentage correctly identified. The statistical analysis result shows that bold highlighting had the shortest search time, and color highlighting had the worst accuracy. Under the conditions of this experiment, bold highlighting should contribute to the design of the screen for an easier search of information in terms of both search speed and accuracy. en-copyright= kn-copyright= en-aut-name=DoiToshihisa en-aut-sei=Doi en-aut-mei=Toshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=4 article-no= start-page=1481 end-page=1509 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202169 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Foreign investment or divestment as a near-term solution to performance shortfalls? The moderating role of vicarious learning en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most studies on problemistic search do not pay sufficient attention to how below-aspiration organizations decide what types of strategic actions to use to cope with performance shortfalls. In this study, we examine the preferences of multinational corporations (MNCs) for selecting foreign investment or divestment as a near-term solution to performance shortfalls. We first argue that foreign divestment is generally a more preferred performance solution. Drawing on the literature on vicarious learning, we further argue that MNCs are more likely to engage in foreign investment or foreign divestment to combat large performance shortfalls if peers recently and actively undertook the same type of strategic action. Moreover, they are less likely to undertake the other type of strategic action simultaneously because they adopt the satisficing principle and time constraints deter them from implementing multiple types of strategic action substantially. The analysis of the data about Japanese manufacturing MNCs reveals that vicarious learning influences MNCs’ selection preferences in certain conditions, thereby extending the literature on problemistic search. en-copyright= kn-copyright= en-aut-name=HuiKent Ngan-Cheung en-aut-sei=Hui en-aut-mei=Kent Ngan-Cheung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Gong Yuanyuan en-aut-sei=Gong en-aut-mei=Yuanyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CuiQi en-aut-sei=Cui en-aut-mei=Qi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangNaipeng en-aut-sei=Jiang en-aut-mei=Naipeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=School of Management, Xiamen University kn-affil= affil-num=2 en-affil=Discovery Program for Global Learners, Okayama University kn-affil= affil-num=3 en-affil=Department of Organization and Human Resources, Renmin University kn-affil= affil-num=4 en-affil=Tourism Department, Fudan University kn-affil= en-keyword=Problemistic search kn-keyword=Problemistic search en-keyword=Vicarious learning kn-keyword=Vicarious learning en-keyword=Japan kn-keyword=Japan en-keyword=Turnaround kn-keyword=Turnaround en-keyword=Foreign investment and divestment kn-keyword=Foreign investment and divestment END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue= article-no= start-page=47 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Information and communication technology equipment and services for remote monitoring and health management: Survey of services and their classification for use in home care nursing kn-title=遠隔での見守りのための機器・サービスの調査と訪問看護での利用を想定した分類 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aims to improve the quality of home nursing care for the elderly. The report presents web-based information about devices and services for remote monitoring and health management using information and communication technology and about how they can improve home care nursing station efficiency in Japan. The search terms "elderly people," "watch over," and "service," plus "sensor" were used to narrow the search. After repeating the search using a chained search for materials and links extracted from those search results, services for home care stations particularly addressing the remote monitoring of elderly people were selected and extracted. Early detection of abnormalities for support by home health nurse responsibilities for observing the general condition of the patient was chosen as the main evaluation index of usefulness. The contractor and service cost were secondary evaluation axes. Results show 9 information communication devices and services for real-time monitoring of the elderly persons’ vital signs in real time for 24 hr, 2 of which are highly useful for early detection of abnormalities and subsequent response. Results suggest that other services might be more useful, depending on how they are used, and that general-purpose services with minimum functions and low cost of introduction and maintenance can provide more opportunities for utilization. Providing these services on a BtoBtoC model and responding to patients’ medical needs can supplement home care nursing station work, increase human resource and time efficiencies, and give patients "the feeling that a nurse is always at their bedside,” even when far away. en-copyright= kn-copyright= en-aut-name=SakamotoToshio en-aut-sei=Sakamoto en-aut-mei=Toshio kn-aut-name=坂本年生 kn-aut-sei=坂本 kn-aut-mei=年生 aut-affil-num=1 ORCID= en-aut-name=HirataAkina en-aut-sei=Hirata en-aut-mei=Akina kn-aut-name=平田晶奈 kn-aut-sei=平田 kn-aut-mei=晶奈 aut-affil-num=2 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name=森田瑞樹 kn-aut-sei=森田 kn-aut-mei=瑞樹 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil=岡山大学大学院ヘルスシステム統合科学研究科 affil-num=2 en-affil=Yell Co., Ltd. kn-affil=株式会社エール affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil=岡山大学大学院ヘルスシステム統合科学研究科 en-keyword=elderly people kn-keyword=elderly people en-keyword=watch over kn-keyword=watch over en-keyword=sensor kn-keyword=sensor en-keyword=in home care support kn-keyword=in home care support en-keyword=telenursing kn-keyword=telenursing END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=100107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese Lung Cancer Society Guidelines for Stage IV NSCLC With EGFR Mutations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with NSCLC in East Asia, including Japan, frequently contain EGFR mutations. In 2018, we published the latest full clinical practice guidelines on the basis of those provided by the Japanese Lung Cancer Society Guidelines Committee. The purpose of this study was to update those recommendations, especially for the treatment of metastatic or recurrent EGFR-mutated NSCLC. We conducted a literature search of systematic reviews of randomized controlled and nonrandomized trials published between 2018 and 2019 that multiple physicians had reviewed independently. On the basis of those studies and the advice from the Japanese Society of Lung Cancer Expert Panel, we developed updated guidelines according to the Grading of Recommendations, Assessment, Development, and Evaluation system. We also evaluated the benefits of overall and progression-free survival, end points, toxicities, and patients’ reported outcomes. For patients with NSCLC harboring EGFR-activating mutations, the use of EGFR tyrosine kinase inhibitors (EGFR TKIs), especially osimertinib, had the best recommendation as to first-line treatment. We also recommended the combination of EGFR TKI with other agents (platinum-based chemotherapy or antiangiogenic agents); however, it can lead to toxicity. In the presence of EGFR uncommon mutations, except for an exon 20 insertion, we also recommended the EGFR TKI treatment. However, we could not provide recommendations for the treatment of EGFR mutations with immune checkpoint inhibitors, including monotherapy, and its combination with cytotoxic chemotherapy, because of the limited evidence present in the literature.

Recurrence en-subtitle= kn-subtitle= en-abstract= kn-abstract=Context
Patients with intermediate-risk non–muscle-invasive bladder cancer (NMIBC) may pose a clinical dilemma without an agreed evidence-based decision tree for personalized treatment.
Objective
To perform a systematic review and network meta-analysis (NMA) to summarize available evidence on the oncologic outcomes of intravesical therapy in patients with intermediate-risk NMIBC.
Evidence acquisition
The MEDLINE, EMBASE, and ClinicalTrials.gov databases were searched in October 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Studies were deemed eligible if they reported on oncologic outcomes in patients with intermediate-risk NMIBC treated with transurethral resection of bladder tumor with and without intravesical chemotherapy or bacillus Calmette-Guérin (BCG) immunotherapy.
Evidence synthesis
Twelve studies were included in a qualitative synthesis (systematic review); three were deemed eligible for a quantitative synthesis (NMA). An NMA of five different regimens was conducted for the association of treatment with the 5-yr recurrence risk. Chemotherapy with maintenance was associated with a lower likelihood of 5-yr recurrence than chemotherapy without maintenance (odds ratio [OR] 0.51, 95% credible interval [CI] 0.26–1.03). Immunotherapy, regardless of whether a full- or reduced-dose regimen, was not associated with a significantly lower likelihood of 5-yr recurrence when compared with chemotherapy without maintenance (OR 0.90, 95% CI 0.39–2.11 vs OR 0.93, 95% CI 0.40–2.19). Analysis of the treatment ranking revealed that chemotherapy with maintenance had the lowest 5-yr recurrence risk (P score 0.9666).
Conclusions
Our analysis indicates that chemotherapy with a maintenance regimen confers a superior oncologic benefit in terms of 5-yr recurrence risk compared to chemotherapy without maintenance in patients with intermediate-risk NMIBC. Regardless of the dose regimen, immunotherapy with BCG does not appear to be superior to chemotherapy in patients with intermediate-risk NMIBC in term of disease recurrence. However, owing to the lack of comparative studies, there is an unmet need for well-designed, large-scale trials to validate our findings and generate robust evidence on disease recurrence and progression.
Patient summary
A maintenance schedule of chemotherapy reduces the rate of long-term recurrence of bladder cancer that has not invaded the bladder muscle. Chemotherapy inserted directly into the bladder and immunotherapy without maintenance schedules seem to have limited benefit in preventing cancer recurrence. en-copyright= kn-copyright=

biomarkers in patients treated with neoadjuvant systemic therapy for urothelial carcinoma of the bladder: a systematic review en-subtitle= kn-subtitle= en-abstract= kn-abstract=PURPOSE
The present systematic review aimed to identify prognostic values of tissue-based biomarkers in patients treated with neoadjuvant systemic therapy (NAST), including chemotherapy (NAC) and checkpoint inhibitors (NAI) for urothelial carcinoma of the bladder (UCB).
MATERIAL AND METHODS
The PubMed, Web of Science, and Scopus databases were searched in August 2020 according to the PRISMA statement. Studies were deemed eligible if they compared oncologic or pathologic outcomes in patients treated with NAST for UCB with and without detected pretreatment tissue-based biomarkers.
RESULTS
Overall, 44 studies met our eligibility criteria. Twenty-three studies used immunohistochemistry (IHC), 19 – gene expression analysis, three - quantitative polymerase chain reaction (QT PCR), and two – next-generation sequencing (NGS). According to the currently available literature, predictive IHC-assessed biomarkers, such as receptor tyrosine kinases and DNA repair pathway alterations, do not seem to convincingly improve our prediction of pathologic response and oncologic outcomes after NAC. Luminal and basal tumor subtypes based on gene expression analysis showed better NAC response, while claudin-low and luminal-infiltrated tumor subtypes did not. In terms of NAI, PD-L1 seems to maintain value as a predictive biomarker, while the utility of both tumor mutational burden and molecular subtypes remains controversial. Specific genomic alterations in DNA repair genes have been shown to provide significant predictive value in patient treated with NAC. QT PCR quantification of specific genes selected through microarray analysis seems to classify cases regarding their NAC response.
CONCLUSION
We believe that the present systematic review may offer a robust framework that will enable the testing and validation of predictive biomarkers in future prospective clinical trials. NGS has expanded the discovery of molecular markers that are reflective of the mechanisms of the NAST response. en-copyright= kn-copyright= en-aut-name=LaukhtinaEkaterina en-aut-sei=Laukhtina en-aut-mei=Ekaterina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PradereBenjamin en-aut-sei=Pradere en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriKeiichiro en-aut-sei=Mori en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SchuettfortVictor M. en-aut-sei=Schuettfort en-aut-mei=Victor M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=QuhalFahad en-aut-sei=Quhal en-aut-mei=Fahad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MostafaeiHadi en-aut-sei=Mostafaei en-aut-mei=Hadi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Sari MotlanghReza en-aut-sei=Sari Motlangh en-aut-mei=Reza kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GrossmannNico C. en-aut-sei=Grossmann en-aut-mei=Nico C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MoschiniMarco en-aut-sei=Moschini en-aut-mei=Marco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EnikeevDmitry en-aut-sei=Enikeev en-aut-mei=Dmitry kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ShariatShahrokh F. en-aut-sei=Shariat en-aut-mei=Shahrokh F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=2 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=3 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=4 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=5 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=6 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=7 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= affil-num=10 en-affil=Department of Urology, Luzerner Kantonsspital kn-affil= affil-num=11 en-affil=Institute for Urology and Reproductive Health, Sechenov University, kn-affil= affil-num=12 en-affil=Department of Urology, Comprehensive Cancer Center, Medical University of Vienna kn-affil= en-keyword=Biomarkers kn-keyword=Biomarkers en-keyword=UCB kn-keyword=UCB en-keyword=bladder cancer kn-keyword=bladder cancer en-keyword=Neoadjuvant systemic therapy kn-keyword=Neoadjuvant systemic therapy en-keyword=NAC kn-keyword=NAC en-keyword=systematic review kn-keyword=systematic review END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=11 article-no= start-page=1534 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Learning for Osteoporosis Classification Using Hip Radiographs and Patient Clinical Covariates en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study considers the use of deep learning to diagnose osteoporosis from hip radiographs, and whether adding clinical data improves diagnostic performance over the image mode alone. For objective labeling, we collected a dataset containing 1131 images from patients who underwent both skeletal bone mineral density measurement and hip radiography at a single general hospital between 2014 and 2019. Osteoporosis was assessed from the hip radiographs using five convolutional neural network (CNN) models. We also investigated ensemble models with clinical covariates added to each CNN. The accuracy, precision, recall, specificity, negative predictive value (npv), F1 score, and area under the curve (AUC) score were calculated for each network. In the evaluation of the five CNN models using only hip radiographs, GoogleNet and EfficientNet b3 exhibited the best accuracy, precision, and specificity. Among the five ensemble models, EfficientNet b3 exhibited the best accuracy, recall, npv, F1 score, and AUC score when patient variables were included. The CNN models diagnosed osteoporosis from hip radiographs with high accuracy, and their performance improved further with the addition of clinical covariates from patient records. en-copyright= kn-copyright= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamuraAkira en-aut-sei=Kitamura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoRyosuke en-aut-sei=Goto en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawasakiKeisuke en-aut-sei=Kawasaki en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FurukiYoshihiko en-aut-sei=Furuki en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Search Space Inc. kn-affil= affil-num=4 en-affil=Search Space Inc. kn-affil= affil-num=5 en-affil=Department of Musculoskeletal Traumatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=osteoporosis kn-keyword=osteoporosis en-keyword=deep learning kn-keyword=deep learning en-keyword=hip radiograph kn-keyword=hip radiograph en-keyword=ensemble model kn-keyword=ensemble model END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=1 article-no= start-page=53 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Remark on a Paper by Izadi and Baghalaghdam about Cubes and Fifth Powers Sums en-subtitle= kn-subtitle= en-abstract= kn-abstract= In this paper, we refine the method introduced by Izadi and Baghalaghdam to search integer solutions to the Diophantine equation.

The genomic RNAs of known polymycoviruses, which show a phylogenetic affinity for animal positive-sense single-stranded RNA [(+)RNA] viruses such as caliciviruses, are comprised of four conserved segments with an additional zero to four segments. The double-stranded form of polymycovirus genomic RNA is assumed to be associated with a virally encoded protein (proline-alanine-serine-rich protein [PASrp]) in either of two manners: a capsidless colloidal form or a filamentous encapsidated form. Detailed molecular characterizations of polymycoviruses, however, have been conducted for only a few strains. Here, a novel polymyco-related virus named Hadaka virus 1 (HadV1), from the phytopathogenic fungus Fusarium oxysporum, was characterized. The genomic RNA of HadV1 consisted of an 11-segmented positive-sense RNA with highly conserved terminal nucleotide sequences. HadV1 shared the three conserved segments with known polymycoviruses but lacked the PASrp-encoding segment. Unlike the known polymycoviruses and encapsidated viruses, HadV1 was not pelleted by conventional ultracentrifugation, possibly due to the lack of PASrp. This result implied that HadV1 exists only as a soluble form with naked RNA. Nevertheless, the 11 genomic segments of HadV1 have been stably maintained through host subculturing and conidiation. Taken together, the results of this study revealed a virus with a potential novel virus lifestyle, carrying many genomic segments without typical capsids or PASrp-associated forms. IMPORTANCE Fungi collectively host various RNA viruses. Examples include encapsidated double-stranded RNA (dsRNA) viruses with diverse numbers of genomic segments (from 1 to 12) and capsidless viruses with nonsegmented (+)RNA genomes. Recently, viruses with unusual intermediate features of an infectious entity between encapsidated dsRNA viruses and capsidless (+)RNA viruses were found. They are called polymycoviruses, which typically have four to eight dsRNA genomic segments associated with one of the virus-encoded proteins and are phylogenetically distantly related to animal (+)RNA caliciviruses. Here, we identified a novel virus phylogenetically related to polymycoviruses, from the phytopathogenic fungus Fusarium oxysporum. The virus, termed Hadaka virus 1 (HadV1), has 11 (+)RNA genomic segments, the largest number in known (+)RNA viruses. Nevertheless, HadV1 lacked a typical structural protein of polymycoviruses and was not pelleted by standard ultracentrifugation, implying an unusual capsidless nature of HadV1. This study reveals a potential novel lifestyle of multisegmented RNA viruses. en-copyright= kn-copyright= en-aut-name=SatoYukiyo en-aut-sei=Sato en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShamsiWajeeha en-aut-sei=Shamsi en-aut-mei=Wajeeha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JamalAtif en-aut-sei=Jamal en-aut-mei=Atif kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BhattiMuhammad Faraz en-aut-sei=Bhatti en-aut-mei=Muhammad Faraz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= 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=Crop Diseases Research Institute, National Agricultural Research Centre kn-affil= affil-num=4 en-affil=Atta-ur-Rahman School of Applied Biosciences (ASAB), National University of Sciences and Technology (NUST) kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=fungal virus kn-keyword=fungal virus en-keyword=polymycovirus kn-keyword=polymycovirus en-keyword=Fusarium oxysporum kn-keyword=Fusarium oxysporum en-keyword=multisegmented kn-keyword=multisegmented en-keyword=RNA virus kn-keyword=RNA virus en-keyword=capsidless kn-keyword=capsidless en-keyword=neo-virus lifestyle kn-keyword=neo-virus lifestyle END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=2 article-no= start-page=231 end-page=240 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=DNA markers based on retrotransposon insertion polymorphisms can detect short DNA fragments for strawberry cultivar identification en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, DNA markers were developed for discrimination of strawberry (Fragaria × ananassa L.) cultivars based on retrotransposon insertion polymorphisms. We performed a comprehensive genomic search to identify retrotransposon insertion sites and subsequently selected one retrotransposon family, designated CL3, which provided reliable discrimination among strawberry cultivars. Through analyses of 75 strawberry cultivars, we developed eight cultivar-specific markers based on CL3 retrotransposon insertion sites. Used in combination with 10 additional polymorphic markers, we differentiated 35 strawberry cultivars commonly cultivated in Japan. In addition, we demonstrated that the retrotransposon-based markers were effective for PCR detection of DNA extracted from processed food materials, whereas a SSR marker was ineffective. These results indicated that the retrotransposon-based markers are useful for cultivar discrimination for processed food products, such as jams, in which DNA may be fragmented or degraded. en-copyright= kn-copyright= en-aut-name=HirataChiharu en-aut-sei=Hirata en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakiTakamitsu en-aut-sei=Waki en-aut-mei=Takamitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimomuraKatsumi en-aut-sei=Shimomura en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaTakuya en-aut-sei=Wada en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaSeiya en-aut-sei=Tanaka en-aut-mei=Seiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkegamiHidetoshi en-aut-sei=Ikegami en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UchimuraYousuke en-aut-sei=Uchimura en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirashimaKeita en-aut-sei=Hirashima en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakazawaYoshiko en-aut-sei=Nakazawa en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaKaori en-aut-sei=Okada en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NamaiKiyoshi en-aut-sei=Namai en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TaharaMakoto en-aut-sei=Tahara en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=2 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=3 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=4 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=5 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= affil-num=6 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=7 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=8 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=9 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=10 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=11 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=13 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Fragaria × ananassa kn-keyword=Fragaria × ananassa en-keyword=high-throughput sequencing kn-keyword=high-throughput sequencing en-keyword=PCR product kn-keyword=PCR product en-keyword=processed foods kn-keyword=processed foods en-keyword=retrotransposon insertion polymorphisms kn-keyword=retrotransposon insertion polymorphisms END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=3 article-no= start-page=119 end-page=123 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cerebral circulation improves with indirect bypass surgery combined with gene therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Angiogenesis involves new blood vessels sprouting from preexisting blood vessels. This process may serve to improve brain circulation. Moyamoya disease (MMD) is a cerebrovascular disorder causing intracranial stenosis which significantly reduces the blood supply to the brain. Mainly stroke is the first symptom of the disorder, so treatments that reduce the risk of stroke are used for patients with MMD. To prevent stroke for those with chronic cerebral hypoperfusion, more blood needs to flow to the brain, which was thought to be achieved by enhancing angiogenesis. Indirect bypass surgery, such as encephalo-myo-synangiosis (EMS), is used for revascularization. However, EMS alone sometimes cannot provide enough circulation to avoid ischemic strokes. The current study examined if EMS combined with high-mobility group box-1 (HMGB1) and vascular endothelial growth factor (VEGF) enhanced angiogenesis and increased cerebral circulation. The results indicated that HMGB1 administered with EMS increased angiogenesis through a VEGF-dependent mechanism. In addition, exercising and stem cell transplantation possess possible means to increase angiogenesis. Overall, EMS with gene therapy, maintaining fitness, and stem cell utilization may prevent or help one recover from stroke by enhancing brain angiogenesis. Thus, these treatments may be applicable for patients with MMD. This paper is a review article. Referred literature in this paper has been listed in the references section.

Traditionally, locoregional surgery is performed only for local control, such as to prevent ulceration and bleeding. In recent years, however, both retrospective and prospective studies have demonstrated the prognostic efficacy of primary surgery for de novo stage IV patients. Therefore, we conducted a meta-analysis to evaluate whether surgical therapy contributes to overall survival (OS) extension. We searched for clinical trials published in electronic databases (PubMed, Embase, and the Cochrane databases) and performed a meta-analysis of the data collected. There were five prospective randomized controlled phase III trials (RCTs). The results of three have been reported. According to our meta-analysis of these RCTs, primary surgery for de novo stage IV breast cancer patients significantly improves OS. However, the Tata trial showed that systemic therapy does not achieve a sufficient effect. Another trial, conducted in Turkey, had statistical shortcomings and patient randomization was not adequately performed The ABCSG (Austrian Breast and Colorectal Cancer Study Group) trial had too few subjects. Meta-analysis of 12 retrospective studies showed that patients with stage IV breast cancer receiving surgery as the initial treatment experienced longer OS (HR: 0.65, P<0.00001). Based on our meta-analysis of three reported 'RCTs, surgery as the primary treatment does not significantly impact the outcomes of de novo stage IV breast cancer patients. However, these trials had limitations. We await the results of the remaining two ongoing RCTs (ECOG 2108 and JCOG 1017). These trials are anticipated to resolve current controversies and provide many eagerly awaited answers. 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=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=metastatic kn-keyword=metastatic en-keyword=stage IV kn-keyword=stage IV en-keyword=local therapy kn-keyword=local therapy en-keyword=locoregional therapy kn-keyword=locoregional therapy en-keyword=surgery kn-keyword=surgery en-keyword=survival kn-keyword=survival END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=1 article-no= start-page=175 end-page=178 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Peritonsillar abscess with otorrhea kn-title=耳漏を主訴に来院した扁桃周囲膿瘍の1例 en-subtitle= kn-subtitle= en-abstract= kn-abstract= The patient was a 79-year-old woman. Her left ear was being treated with otitis externa at her nearby clinic by eardrop. Her otorrhea did not improve after one week. The otorrhea still kept outflowing during food intake. That is the reason of her visiting our hospital. Her past medical histories were sigmoid colon perforation with stoma placement, rheumatoid arthritis, diabetes mellitus, hypertension, right hip prosthesis placement. At the first visit to our hospita!, She had a remarkable erosion of the left ear canal, fistula was found in front of the ear canal skin. She showed pus leakage due to her chewing. Strongly swelling surrounded the left tonsil and soft palate, and oropharynx had been narrowed. T he CT scan revealed the low density area with a contrast effect from the lower ear to the left tonsil, was diagnosed with left peritonsillar abscess. On admission to our hospital, drainage and the administration of antibiotics were performed. She was discharged in satisfactory progress on day 10. Peritonsillar abscess, but there is a frequently encountered disease, being the chief complaint otorrhea is rare. As reported case seems to be similar as far as we have searched is only reported as "one case of deep neck abscess in the throat and ear canal causing self-destruction" is Tomohiro Anno 1961.

This study searched the timing of diagnosis of anisometropia in children with congenital blepharoptosis.
Methods: Retrospective review was made on medical records of 20 consecutive patients with congenital blepharoptosis at Okayama University Hospital from 2004 to 2018.
Results: T he age at the initial visit ranged from 1 month to 5 years 1 month (median, 5.5 months), and the follow-up period from 1 year 8 months to 13 years 5 months (median, 5 years 5 months). Blepharoptosis was on the right side in 6 patients, on the left side in 10, and on both sides in 4. Four patients underwent levator muscle plication at the age ranging from 3 months to 6 years 2 months: One patient on the right side, 2 on the left side, and one on both sides. Nine patients were found to have anisometropia, defined as hyperopic difference of 2 or more diopters between both eyes, or astigmatic difference of 2 or more diopters between both eyes, and astigmatism of 3 or more diopters in both eyes (ametropia), at the age ranging from 1 year 3 months to 3 years 6 months (median, 3 years). Four of the 9 patients with anisometropia showed unilateral amblyopia as the best-corrected visual acuity in decimals ranging from 0.2 to 0.5. The remaining 11 patients without anisometropia had normal levels of visual acuity in both eyes. Anisometropia was found in 3 of 4 patients with surgery and 6 of 16 patients with no surgery (no significant difference at chi-square test).
Conclusion: About a half of children with congenital blepharoptosis was found to have anisometropia at the age of 1 to 3 years. Care must be taken on refraction and glasses prescription at these ages. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Okayama University Graduate School of Interdisciplinary Science and Engineering in Health Systems kn-affil= en-keyword=Congenital blepharoptosis kn-keyword=Congenital blepharoptosis en-keyword=Anisometropia kn-keyword=Anisometropia en-keyword=Levater muscle placation kn-keyword=Levater muscle placation END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=509 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Virome Analysis of Aphid Populations That Infest the Barley Field: The Discovery of Two Novel Groups of Nege/Kita-Like Viruses and Other Novel RNA Viruses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aphids (order Hemiptera) are important insect pests of crops and are also vectors of many plant viruses. However, little is known about aphid-infecting viruses, particularly their diversity and relationship to plant viruses. To investigate the aphid viromes, we performed deep sequencing analyses of the aphid transcriptomes from infested barley plants in a field in Japan. We discovered virus-like sequences related to nege/kita-, flavi-, tombus-, phenui-, mononega-, narna-, chryso-, partiti-, and luteoviruses. Using RT-PCR and sequence analyses, we determined almost complete sequences of seven nege/kitavirus-like virus genomes; one of which was a variant of the Wuhan house centipede virus (WHCV-1). The other six seem to belong to four novel viruses distantly related to Wuhan insect virus 9 (WhIV-9) or Hubei nege-like virus 4 (HVLV-4). We designated the four viruses as barley aphid RNA virus 1 to 4 (BARV-1 to -4). Moreover, some nege/kitavirus-like sequences were found by searches on the transcriptome shotgun assembly (TSA) libraries of arthropods and plants. Phylogenetic analyses showed that BARV-1 forms a clade with WHCV-1 and HVLV-4, whereas BARV-2 to -4 clustered with WhIV-9 and an aphid virus, Aphis glycines virus 3. Both virus groups (tentatively designated as Centivirus and Aphiglyvirus, respectively), together with arthropod virus-like TSAs, fill the phylogenetic gaps between the negeviruses and kitaviruses lineages. We also characterized the flavi/jingmen-like and tombus-like virus sequences as well as other RNA viruses, including six putative novel viruses, designated as barley aphid RNA viruses 5 to 10. Interestingly, we also discovered that some aphid-associated viruses, including nege/kita-like viruses, were present in different aphid species, raising a speculation that these viruses might be distributed across different aphid species with plants being the reservoirs. This study provides novel information on the diversity and spread of nege/kitavirus-related viruses and other RNA viruses that are associated with aphids. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=College of Plant Health and Medicine, Qingdao Agricultural University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=negevirus kn-keyword=negevirus en-keyword=kitavirus kn-keyword=kitavirus en-keyword=aphid kn-keyword=aphid en-keyword=virome kn-keyword=virome en-keyword=RNA seq kn-keyword=RNA seq en-keyword=barley kn-keyword=barley en-keyword=diversity kn-keyword=diversity en-keyword=horizontal transmission kn-keyword=horizontal transmission END start-ver=1.4 cd-journal=joma no-vol=959 cd-vols= no-issue= article-no= start-page=163549 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of gadolinium’s action on water Cherenkov detector systems with EGADS en-subtitle= kn-subtitle= en-abstract= kn-abstract= Used for both proton decay searches and neutrino physics, large water Cherenkov (WC) detectors have been very successful tools in particle physics. They are notable for their large masses and charged particle detection capabilities. While current WC detectors reconstruct charged particle tracks over a wide energy range, they cannot efficiently detect neutrons. Gadolinium (Gd) has the largest thermal neutron capture cross section of all stable nuclei and produces an 8 MeV gamma cascade that can be detected with high efficiency. Because of the many new physics opportunities that neutron tagging with a Gd salt dissolved in water would open up, a large-scale R&D program called EGADS was established to demonstrate this technique’s feasibility. EGADS features all the components of a WC detector, chiefly a 200-ton stainless steel water tank furnished with 240 photo-detectors, DAQ, and a water system that removes all impurities from water while keeping Gd in solution. In this paper we discuss the milestones towards demonstrating the feasibility of this novel technique, and the features of EGADS in detail. en-copyright= kn-copyright= en-aut-name=MartiLl.

No evidence for heavy neutrinos was observed. Upper limits were set on the neutrino mixing matrix vertical bar U-mu i vertical bar(2) in the neutrino mass region of 15.7-33.8 MeV/c(2), improving on previous results by an order of magnitude.

Forty 5-6 aged children participated in the study, and we assessed on three skills: orthographic knowledge of long-vowel words, reading fluency, word play. The results of correlation analysis showed that orthographic knowledge of long-vowel words was moderately related to reading fluency. In addition, the results of multiple regression analysis showed that age and scores of word play variables were predictors of reading fluency. The findings provide further evidence for the relationship between reading fluency and word play that were demanded th e skills of phonological manipulatio n and word search. kn-abstract= 本研究は，年長児のことば遊び，長音表記知識，およびひらがな単語読字の流暢性との関連を明らかにすることを目的とした。年長児40 名を対象に，文字を使ったことば遊びである“ことばのかくれんぼゲーム”，かな読み中後期の発達課題である，ひらがな長音単語の表記知識課題，ひらがな単語速読課題を実施した。各課題の相関から，ひらがな単語速読成績と長音表記選択課題の分節回答成績で有意な関連が認められた。また，ことばのかくれんぼゲーム成績，長音表記選択成績，月齢を独立変数，ひらがな単語速読成績を従属変数とした重回帰分析の結果，ことばのかくれんぼゲームの「部分文字列」成績と月齢が有意な予測変数として抽出された。本研究から，年長児におけるひらがな単語読字の流暢性には，ことばの音韻操作を駆使してことばを見つける力や，有意味な文字列をすばやく見つける力を必要とされるような，ことば遊びが関与することが示唆された。 en-copyright= kn-copyright= en-aut-name=YOKOYAMAMoe en-aut-sei=YOKOYAMA en-aut-mei=Moe kn-aut-name=横山萌 kn-aut-sei=横山 kn-aut-mei=萌 aut-affil-num=1 ORCID= en-aut-name=TANJITakayuki en-aut-sei=TANJI en-aut-mei=Takayuki kn-aut-name=丹治敬之 kn-aut-sei=丹治 kn-aut-mei=敬之 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=佐用町立上月小学校 affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科 en-keyword=年長児 (Preschool children) kn-keyword=年長児 (Preschool children) en-keyword=ひらがな単語の読字 (Hiragana Word Reading) kn-keyword=ひらがな単語の読字 (Hiragana Word Reading) en-keyword=ことば遊び (Word Play) kn-keyword=ことば遊び (Word Play) en-keyword=流暢性 (Fluency) kn-keyword=流暢性 (Fluency) END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=211 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic significance of the controlling nutritional status (CONUT) score in patients undergoing hepatectomy for hepatocellular carcinoma: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The clinical value of the controlling nutritional status (CONUT) score in hepatocellular carcinoma (HCC) has increased. The aim of this meta-analysis was to systematically review the association between the CONUT score and outcomes in patients undergoing hepatectomy for HCC.
Methods: Embase, Medline Ovid, Web of Science, Cochrane CENTRAL, and Google Scholar were systematically searched. Random effects meta-analyses were conducted to examine the prognostic value of the CONUT score in HCC patients.
Results: A total of five studies including 4679 patients were found to be eligible and analyzed in the meta-analysis. The CONUT score was significantly associated with overall survival (HR 1.78, 95%CI = 1.20-2.64, P = 0.004, I-2 = 79%), recurrence-free survival (HR 1.34, 95%CI = 1.17-1.53, P < 0.001, I-2 = 16%) and postoperative major complications (OR 1.85, 95%CI: 1.19-2.87, P = 0.006, I-2 = 72%) in HCC patients. Moreover, the CONUT score was associated with the Child-Pugh classification, liver cirrhosis, ICGR15, and tumor differentiation. However, it was not associated with tumor size, tumor number, and microvascular invasion.
Conclusions: The CONUT score is an independent prognostic indicator of the prognosis and is associated with postoperative major complications and hepatic functional reserve in HCC patients. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DomagalaPiotr en-aut-sei=Domagala en-aut-mei=Piotr kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PolakWojciech G. en-aut-sei=Polak en-aut-mei=Wojciech G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BuettnerStefan en-aut-sei=Buettner en-aut-mei=Stefan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IjzermansJan N.

Large amounts of Gd are used in these experiments. To assess the impact of Gd on the environment it is becoming important to measure the baseline concentrations of Gd. Such measurement, however, is not easy due to interference by other elements. In this paper a method for measuring the concentrations of rare earth elements, including Gd, is proposed. In the method, inductively coupled plasma-mass spectrometry is utilized after collecting the dissolved elements in chelating resin. Results of the ability to detect anomalous concentrations of rare earth elements in river water samples in the Kamioka and Toyama areas are also reported. en-copyright= kn-copyright= en-aut-name=ItoS. en-aut-sei=Ito en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaT. en-aut-sei=Okada en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakuY. en-aut-sei=Takaku en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaradaM. en-aut-sei=Harada en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaM. en-aut-sei=Ikeda en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishimotoY. en-aut-sei=Kishimoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KoshioY. en-aut-sei=Koshio en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakahataM. en-aut-sei=Nakahata en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakajimaY. en-aut-sei=Nakajima en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SekiyaH. en-aut-sei=Sekiya en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Okayama University, Faculty of Science kn-affil= affil-num=2 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=3 en-affil=Institute for Environmental Sciences, Department of Radioecology kn-affil= affil-num=4 en-affil=Okayama University, Faculty of Science kn-affil= affil-num=5 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=6 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=7 en-affil=Okayama University, Faculty of Science kn-affil= affil-num=8 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=9 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=10 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a separable search-and-rescue robot composed of a mobile robot and a snake robot en-subtitle= kn-subtitle= en-abstract= kn-abstract= In this study, we propose a new robot system consisting of a mobile robot and a snake robot. The system works not only as a mobile manipulator but also as a multi-agent system by using the snake robot's ability to separate from the mobile robot. Initially, the snake robot is mounted on the mobile robot in the carrying mode. When an operator uses the snake robot as a manipulator, the robot changes to the manipulator mode. The operator can detach the snake robot from the mobile robot and command the snake robot to conduct lateral rolling motions. In this paper, we present the details of our robot and its performance in the World Robot Summit. en-copyright= kn-copyright= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkiyamaTaichi en-aut-sei=Akiyama en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaiSatoshi en-aut-sei=Sakai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiKento en-aut-sei=Fujii en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UneKazushi en-aut-sei=Une en-aut-mei=Kazushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OuEitou en-aut-sei=Ou en-aut-mei=Eitou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumuraYuto en-aut-sei=Matsumura en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KishutaniToru en-aut-sei=Kishutani en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NoseEiji en-aut-sei=Nose en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshizakiYusuke en-aut-sei=Yoshizaki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=GofukuAkio en-aut-sei=Gofuku en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=2 en-affil=Graduate School of 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=8 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=10 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= affil-num=11 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, kn-affil= en-keyword=Separable robot kn-keyword=Separable robot en-keyword=snake robot kn-keyword=snake robot en-keyword=mobile robot kn-keyword=mobile robot en-keyword=urban search-and-rescue kn-keyword=urban search-and-rescue en-keyword=multi-agent system kn-keyword=multi-agent system END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=73 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detection and analysis of non-retroviral RNA virus-like elements in plant, fungal, and insect genomes. en-subtitle= kn-subtitle= en-abstract= kn-abstract= Endogenous non-retroviral RNA like sequences (NRVSs) have been discovered in the genome of a wide range of eukaryotes. These are considered as fossil RNA viral elements integrated into host genomes by as-yet-known mechanisms, and in many cases, those fossils are estimated to be millions-of-years-old. It is likely that the number of NRVS records will increase rapidly due to the growing availability of whole-genome sequences for many kinds of eukaryotes. Discovery of the novel NRVSs and understanding of their phylogenetic relationship with modern viral relatives provide important information on deep evolutionary history of RNA virus-host interactions. In this chapter, therefore, the common strategies for the identification and characterization of endogenous NRVSs from plants, insects, and fungi are described. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChibaSotaro en-aut-sei=Chiba en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR)Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Pareovirology kn-keyword=Pareovirology en-keyword=Molecular fossil record kn-keyword=Molecular fossil record en-keyword=Non-retrovirus-like sequence kn-keyword=Non-retrovirus-like sequence en-keyword=Database search kn-keyword=Database search en-keyword=Whole-genome shotgun kn-keyword=Whole-genome shotgun en-keyword=Genomic PCR kn-keyword=Genomic PCR en-keyword=Southern blotting kn-keyword=Southern blotting en-keyword=Phylogenetic analysis kn-keyword=Phylogenetic analysis en-keyword=Maximum-likelihood kn-keyword=Maximum-likelihood END start-ver=1.4 cd-journal=joma no-vol=160 cd-vols= no-issue=8 article-no= start-page=2099 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20150531 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cymbidium chlorotic mosaic virus, a new sobemovirus isolated from a spring orchid (Cymbidium goeringii) in Japan. en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cymbidium chlorotic mosaic virus (CyCMV), isolated from a spring orchid (Cymbidium goeringii), was characterized molecularly. CyCMV isometric virions comprise a single, positive-strand RNA genome of 4,083 nucleotides and 30-kDa coat protein. The virus genome contains five overlapping open reading frames with a genomic organization similar to that of sobemoviruses. BLAST searches and phylogenetic analysis revealed that CyCMV is most closely related to papaya lethal yellowing virus, a proposed dicot-infecting sobemovirus (58.8 % nucleotide sequence identity), but has a relatively distant relationship to monocot-infecting sobemoviruses, with only modest sequence identities. This suggests that CyCMV is a new monocot-infecting member of the floating genus Sobemovirus. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoShogo en-aut-sei=Takemoto en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruyamaKazuyuki en-aut-sei=Maruyama en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChibaSotaro en-aut-sei=Chiba en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Ida Bagus Andika en-aut-sei=Ida Bagus Andika en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR)Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR)Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR)Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR)Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=177 cd-vols= no-issue=1 article-no= start-page=75 end-page=86 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of burdock mottle virus, a novel member of the genus Benyvirus, and the identification of benyvirus-related sequences in the plant and insect genomes. en-subtitle= kn-subtitle= en-abstract= kn-abstract= The complete nucleotide sequence of the burdock mottle virus (BdMoV) isolated from an edible burdock plant (Arctium lappa) in Japan has been determined. BdMoV has a bipartite genome, whose organization is similar to RNA1 and RNA2 of benyviruses, beet necrotic yellow vein virus (BNYVV), beet soil-borne mosaic virus (BSBMV), and rice stripe necrosis virus (RSNV). BdMoV RNA1 (7038 nt) contains a single open reading frame (ORF) encoding a 249-kDa polypeptide that consists of methyl-transferase, helicase, papain-like protease, AlkB-like, and RNA-dependent RNA polymerase domains. The AlkB-like domain sequence is not present in the proteins encoded by other known benyviruses, but is found in replication-associated proteins of viruses mainly belonging to the families Alfaflexiviridae and Betaflexiviridae. BdMoV RNA2 (4315 nt) contains six ORFs that are similar to those of benyviruses: these are coat protein (CP), CP readthrough, triple gene block movement and cysteine-rich proteins. Phylogenetic analyses showed that BdMoV is more closely related to BNYVV and BSBMV than to RSNV. Database searches showed that benyvirus replicase-related sequences are present in the chromosomes of a chickpea plant (Cicer arietinum) and a blood-sucking insect (Rhodnius prolixus). Some other benyvirus-related sequences are found in the transcriptome shotgun libraries of a few species of plants and a bark beetle. Our results show that BdMoV is a distinct species of the genus Benyvirus and that ancestral and extant benyviruses may have infected or currently infect a wide range of hosts, including plants and insects. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranoShuichi en-aut-sei=Hirano en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChibaSotaro en-aut-sei=Chiba en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraiMakoto en-aut-sei=Hirai en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Virology and Biotechnology, Zhejiang Academy of Agricultural Sciences kn-affil= affil-num=5 en-affil=Department of Parasitology, Graduate School of Medicine, Gunma University kn-affil= affil-num=6 en-affil=Formerly College of Bioresource Sciences, Nihon University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=AlkB kn-keyword=AlkB en-keyword=Benyvirus kn-keyword=Benyvirus en-keyword=Burdock mottle virus kn-keyword=Burdock mottle virus en-keyword=Endogenous viral element kn-keyword=Endogenous viral element en-keyword=Paleovirology kn-keyword=Paleovirology en-keyword=Transcriptome shotgun assembly kn-keyword=Transcriptome shotgun assembly END start-ver=1.4 cd-journal=joma no-vol=213 cd-vols= no-issue= article-no= start-page=353 end-page=364 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sequence and phylogenetic analyses of novel totivirus-like double-stranded RNAs from field-collected powdery mildew fungi en-subtitle= kn-subtitle= en-abstract= kn-abstract= The identification of mycoviruses contributes greatly to understanding of the diversity and evolutionary aspects of viruses. Powdery mildew fungi are important and widely studied obligate phytopathogenic agents, but there has been no report on mycoviruses infecting these fungi. In this study, we used a deep sequencing approach to analyze the double-stranded RNA (dsRNA) segments isolated from field-collected samples of powdery mildew fungus-infected red clover plants in Japan. Database searches identified the presence of at least ten totivirus (genus Totivirus)-like sequences, termed red clover powdery mildew-associated totiviruses (RPaTVs). The majority of these sequences shared moderate amino acid sequence identity with each other (<44%) and with other known totiviruses (<59%). Nine of these identified sequences (RPaTV1a, 1b and 2-8) resembled the genome of the prototype totivirus, Saccharomyces cerevisiae virus-L-A (ScV-L-A) in that they contained two overlapping open reading frames (ORFs) encoding a putative coat protein (CP) and an RNA dependent RNA polymerase (RdRp), while one sequence (RPaTV9) showed similarity to another totivirus, Ustilago maydis virus H1 (UmV-H1) that encodes a single polyprotein (CP-RdRp fusion). Similar to yeast totiviruses, each ScV-L-A-like RPaTV contains a -1 ribosomal frameshift site downstream of a predicted pseudoknot structure in the overlapping region of these ORFs, suggesting that the RdRp is translated as a CP-RdRp fusion. Moreover, several ScV-L-A-like sequences were also found by searches of the transcriptome shotgun assembly (TSA) libraries from rust fungi, plants and insects. Phylogenetic analyses show that nine ScV-L-A-like RPaTVs along with ScV-L-A-like sequences derived from TSA libraries are clustered with most established members of the genus Totivirus, while one RPaTV forms a new distinct clade with UmV-H1, possibly establishing an additional genus in the family. Taken together, our results indicate the presence of diverse, novel totiviruses in the powdery mildew fungus populations infecting red clover plants in the field. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChibaSotaro en-aut-sei=Chiba en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamaKazuyuki en-aut-sei=Maruyama en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujimoriFumihiro en-aut-sei=Fujimori en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Environmental Education, Tokyo Kasei University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Deep sequencing kn-keyword=Deep sequencing en-keyword=Double stranded RNA virus kn-keyword=Double stranded RNA virus en-keyword= Powdery mildew kn-keyword= Powdery mildew en-keyword=Saccharomyces cerevisiae virus L-A kn-keyword=Saccharomyces cerevisiae virus L-A en-keyword=Totivirus kn-keyword=Totivirus en-keyword=Ustilago maydis virus H1 kn-keyword=Ustilago maydis virus H1 END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=6 article-no= start-page=1522 end-page=1529 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Artificial selection on walking distance suggests a mobility-sperm competitiveness trade-off en-subtitle= kn-subtitle= en-abstract= kn-abstract= Securing matings is a key determinant of fitness, and in many species, males are the sex that engages in mate searching. Searching for mates is often associated with increased mobility. This elevated investment in movement is predicted to trade-off with sperm competitiveness, but few studies have directly tested whether this trade-off occurs. Here, we assessed whether artificial selection on mobility affected sperm competitiveness and mating behavior, and if increased mobility was due to increased leg length in red flour beetles (Tribolium castaneum). We found that, in general, males selected for decreased mobility copulated for longer, stimulated females more during mating, and tended to be better sperm competitors. Surprisingly, they also had longer legs. However, how well males performed in sperm competition depended on females. Males with reduced mobility always copulated for longer than males with high mobility, but this only translated into greater fertilization success in females from control populations and not the selection populations (i.e. treatment females). These results are consistent with a mate-searching/mating-duration trade-off and broadly support a trade-off between mobility and sperm competitiveness. en-copyright= kn-copyright= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ArcherC Ruth en-aut-sei=Archer en-aut-mei=C Ruth kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Hosken David J en-aut-sei=Hosken en-aut-mei= David J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Centre for Ecology & Conservation, University of Exeter kn-affil= affil-num=3 en-affil=Centre for Ecology & Conservation, University of Exeter kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=leg length kn-keyword=leg length en-keyword=mate searching kn-keyword=mate searching en-keyword=morphology kn-keyword=morphology en-keyword=sperm competition, kn-keyword=sperm competition, en-keyword=trade-off kn-keyword=trade-off en-keyword=Tribolium castaneum kn-keyword=Tribolium castaneum en-keyword=walking kn-keyword=walking END start-ver=1.4 cd-journal=joma no-vol=262 cd-vols= no-issue= article-no= start-page=37 end-page=47 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel insect-infecting virga/nege-like virus group and its pervasive endogenization into insect genomes en-subtitle= kn-subtitle= en-abstract= kn-abstract= Insects are the host and vector of diverse viruses including those that infect vertebrates, plants, and fungi. Recent wide-scale transcriptomic analyses have uncovered the existence of a number of novel insect viruses belonging to an alphavirus-like superfamily (virgavirus/negevirus-related lineage). In this study, through an in silico search using publicly available insect transcriptomic data, we found numerous virus-like sequences related to insect virga/nege-like viruses. Phylogenetic analysis showed that these novel viruses and related virus-like sequences fill the major phylogenetic gaps between insect and plant virga/negevirus lineages. Interestingly, one of the phylogenetic clades represents a unique insect-infecting virus group. Its members encode putative coat proteins which contained a conserved domain similar to that usually found in the coat protein of plant viruses in the family Virgaviridae. Furthermore, we discovered endogenous viral elements (EVEs) related to virga/nege-like viruses in the insect genomes, which enhances our understanding on their evolution. Database searches using the sequence of one member from this group revealed the presence of EVEs in a wide range of insect species, suggesting that there has been prevalent infection by this virus group since ancient times. Besides, we present detailed EVE integration profiles of this virus group in some species of the Bombus genus of bee families. A large variation in EVE patterns among Bombus species suggested that while some integration events occurred after the species divergence, others occurred before it. Our analyses support the view that insect and plant virga/nege-related viruses might share common virus origin(s). en-copyright= kn-copyright= en-aut-name=Kondo Hideki en-aut-sei=Kondo en-aut-mei= Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Chiba Sotaro en-aut-sei=Chiba en-aut-mei= Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Maruyama Kazuyuki en-aut-sei=Maruyama en-aut-mei= Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Andika Ida Bagus en-aut-sei=Andika en-aut-mei= Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Suzuki Nobuhiro en-aut-sei=Suzuki en-aut-mei= Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Asian Satellite Campuses Institute, Nagoya University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Bumblebee kn-keyword=Bumblebee en-keyword=Endogenous viral element kn-keyword=Endogenous viral element en-keyword= Evolution kn-keyword= Evolution en-keyword=Insect kn-keyword=Insect en-keyword= Plant alpha-like virus kn-keyword= Plant alpha-like virus en-keyword=Transcriptome shotgun assembly kn-keyword=Transcriptome shotgun assembly en-keyword=Whole genome shotgun assembly kn-keyword=Whole genome shotgun assembly END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=3 article-no= start-page=145 end-page=154 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A design-aware test code approach for code writing problem in Java programming learning assistant system en-subtitle= kn-subtitle= en-abstract= kn-abstract= To advance Java programming educations, we have developed the web-based Java programming learning assistant system (JPLAS) that provides the code writing problem. This problem asks a student to write a source code for a given assignment, where the correctness is verified by running the test code on JUnit. In this paper, we propose a design-aware test code approach for the code writing problem. The design-aware test code tests any important method in the model source code that has the advisable design for the assignment. Thus, by writing a code that can pass it, a student is expected to implement the code with the proper classes/methods in the model code. In evaluations of the proposal, all the students could complete highly qualitative codes for five graph algorithms using the design-aware test codes, where the code quality metrics were measured by metrics plugin for Eclipse. en-copyright= kn-copyright= en-aut-name=Khin Khin Zaw en-aut-sei=Khin Khin Zaw en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= 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= en-keyword=Java programming learning assistant system kn-keyword=Java programming learning assistant system en-keyword=JPLAS kn-keyword=JPLAS en-keyword=design-aware test code kn-keyword=design-aware test code en-keyword=JUnit kn-keyword=JUnit en-keyword=metric plugin kn-keyword=metric plugin en-keyword=breadth-first-search kn-keyword=breadth-first-search en-keyword=BFS kn-keyword=BFS END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=9 end-page=23 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Application of simulated annealing to focal mechanism determination kn-title=焼きなまし法による初動発震機構解の決定 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Simulated annealing (SA) is known as one of the efficient methods for global optimization.

A unique algorithm for tracking and searching ground images with natural texture is used to localize the robot without a feature-point extraction scheme commonly used in other visual odometry methods. In our tracking algorithm, groups of reference pixels are used to detect the relative translation and rotation between frames. Furthermore, a reference pixel group of another shape is registered both to record a path and to correct errors accumulated during localization. All image processing and robot control operations are carried out with low memory consumption for image registration and fast calculation times for completing the searches on a laptop PC. We also describe experimental results in which a vehicle developed by the proposed method repeatedly performed precise path tracking under indoor and outdoor environments. en-copyright= kn-copyright= en-aut-name=NagaiIsaku en-aut-sei=Nagai en-aut-mei=Isaku kn-aut-name=永井伊作 kn-aut-sei=永井 kn-aut-mei=伊作 aut-affil-num=1 ORCID= en-aut-name=WatanabeKeigo en-aut-sei=Watanabe en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue= article-no= start-page=40 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Practice of the 3Rs in Practical Training Using Animals -Preliminary training for the care, handling, injection and dissection of mice and rats- kn-title=実験動物を用いる実習における3Rs 実践の試み －マウス、ラットの飼育、保定、注射、解剖に向けての予備トレーニング－ en-subtitle= kn-subtitle= en-abstract=In order to improve animal welfare through practical training in laboratory animal techniques at Hiroshima Animal Care College, we have been searching for ways to reduce animal suffering caused by such practical training. Students in the Animal Management Department learn to use animals in the practicum of laboratory animal science in their third year. In order to practice the 3Rs (Reduction, Replacement, and Refinement), we have introduced preliminary training before the students work with live animals. Specifically, the following five practices are introduced: 1. Practice of handling cages 2. Practice of controlling fine manipulation by pinching elastic balls and their own skin 3. Practice of sewing a dust cloth by hand, to learn how to handle sharp instruments 4. Practice of injecting chicken wing tips to learn how to inject animals 5. Practice of dissection techniques using thin pastry, chicken skin, and chicken wing tips We have not objectively verified whether these efforts are effective to reduce animal suffering. However, subjectively, we have observed some positive effects on the students. The primary object of this training is to reduce animal suffering. Furthermore, it may promote the psychological preparation of students who will be using live laboratory animals. Currently, training courses for animal technicians and animal nurses are taught at colleges or universities. From the viewpoints of ethics and animal welfare, it is necessary to refine the practical training program to work with live animals. We report our preliminary training as part of the program. kn-abstract=広島アニマルケア専門学校では、動物看護コース3 年課程（動物看護師志望者と実験動物技術者志望者が混 在）の3 年次に実施する実験動物学実習に際して、動物福祉の観点から動物に与える苦痛を可能な限り少なく できる実施法を模索してきた。実際に生きた動物を用いる実習を行う前に、いくつかの予備トレーニングを取 り入れた3Rs 実践の試みである。具体的には、ケージ取り扱い練習、先鋭器具取り扱い練習のための雑巾縫 製、保定練習を目的とした軟質ボールによる手指トレーニング、自身の皮膚摘まみ練習、鉛筆や鶏手羽先を用 いた注射器具使用練習、そして餃子の皮、鶏皮、鶏手羽先を用いた解剖器具使用練習などである。これらの取 り組みそれぞれが、果たして効果的であるかどうか検証できているわけではないが、学生の取り組みを間近で 観察した立場から、感覚的には効果を実感している。また、予備トレーニングは、動物に与える苦痛を軽減す ることを最大の目標とするものであるが、一方で、動物を用いた実習に臨む学生の心理的準備を促す効果もあ るように感じている。実験動物技術者や動物看護師養成課程、コースが、大学や専門学校に設けられ、そこに 多くの学生が学んでいる現在、動物を用いた実習のプログラムを動物実験倫理・動物福祉の観点からさらに洗 練させることが望まれる。そのプログラムの一部として、われわれの予備トレーニングの取り組みを紹介した。 en-copyright= kn-copyright= en-aut-name=UsudaToshiki en-aut-sei=Usuda en-aut-mei=Toshiki kn-aut-name=臼田俊樹 kn-aut-sei=臼田 kn-aut-mei=俊樹 aut-affil-num=1 ORCID= en-aut-name=FurumotoKayo en-aut-sei=Furumoto en-aut-mei=Kayo kn-aut-name=古本佳代 kn-aut-sei=古本 kn-aut-mei=佳代 aut-affil-num=2 ORCID= en-aut-name=KitaMegumu en-aut-sei=Kita en-aut-mei=Megumu kn-aut-name=北德 kn-aut-sei=北 kn-aut-mei=德 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=広島アニマルケア専門学校動物看護コース affil-num=2 en-affil= kn-affil=広島アニマルケア専門学校動物看護コース affil-num=3 en-affil= kn-affil=倉敷芸術科学大学動物生命科学科 END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=1 article-no= start-page=25 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20150401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Laparoscopic total colectomy with lymph node dissection for familial adenomatous polyposis with multiple colorectal cancers kn-title=家族性大腸腺腫症（FAP）に合併した同時性５多発大腸癌に対してリンパ節郭清を伴う腹腔鏡下大腸全摘術を施行した１例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　A 49-year-old Japanese man visited our hospital with chief complaints of difficulty with and bleeding during defecation. After a detailed examination, he was diagnosed with familial adenomatous polyposis (FAP) with multiple (five) colorectal cancers. The tumors were located in the right-sided, left-sided, and sigmoid colon, and the lower rectum. Regional lymph node involvement was observed, but no metastasis to other organs was detected. We, therefore, performed a laparoscopic total colectomy with superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) lymph node dissection. We were able to perform minimally invasive and cosmetically acceptable surgery using laparoscopy instead of highly-invasive open abdominal surgery. Our search of the literature revealed no reported cases of laparoscopic total colectomy with lymph node dissection for FAP with multiple colorectal cancers, making the present case the first to be reported in the literature. en-copyright= kn-copyright= en-aut-name=KatoHiroshi en-aut-sei=Kato en-aut-mei=Hiroshi kn-aut-name=加藤大 kn-aut-sei=加藤 kn-aut-mei=大 aut-affil-num=1 ORCID= en-aut-name=OishiMasahiro en-aut-sei=Oishi en-aut-mei=Masahiro kn-aut-name=大石正博 kn-aut-sei=大石 kn-aut-mei=正博 aut-affil-num=2 ORCID= en-aut-name=KoderaMasahito en-aut-sei=Kodera en-aut-mei=Masahito kn-aut-name=小寺正人 kn-aut-sei=小寺 kn-aut-mei=正人 aut-affil-num=3 ORCID= en-aut-name=YamamuraMasao en-aut-sei=Yamamura en-aut-mei=Masao kn-aut-name=山村方夫 kn-aut-sei=山村 kn-aut-mei=方夫 aut-affil-num=4 ORCID= en-aut-name=IkedaHideaki en-aut-sei=Ikeda en-aut-mei=Hideaki kn-aut-name=池田秀明 kn-aut-sei=池田 kn-aut-mei=秀明 aut-affil-num=5 ORCID= en-aut-name=MizunoKenji en-aut-sei=Mizuno en-aut-mei=Kenji kn-aut-name=水野憲治 kn-aut-sei=水野 kn-aut-mei=憲治 aut-affil-num=6 ORCID= en-aut-name=YamashitaYutaka en-aut-sei=Yamashita en-aut-mei=Yutaka kn-aut-name=山下裕 kn-aut-sei=山下 kn-aut-mei=裕 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=鳥取市立病院　外科 affil-num=2 en-affil= kn-affil=鳥取市立病院　外科 affil-num=3 en-affil= kn-affil=鳥取市立病院　外科 affil-num=4 en-affil= kn-affil=鳥取市立病院　外科 affil-num=5 en-affil= kn-affil=鳥取市立病院　外科 affil-num=6 en-affil= kn-affil=鳥取市立病院　外科 affil-num=7 en-affil= kn-affil=鳥取市立病院　外科 en-keyword=家族性大腸腺腫症（FAP）（familial adenomatous polyposis） kn-keyword=家族性大腸腺腫症（FAP）（familial adenomatous polyposis） en-keyword=同時性多発大腸癌（synchronous colorectal cancer） kn-keyword=同時性多発大腸癌（synchronous colorectal cancer） en-keyword=大腸全摘術（colorectal surgery） kn-keyword=大腸全摘術（colorectal surgery） en-keyword=腹腔鏡下手術（laparoscopic surgery） kn-keyword=腹腔鏡下手術（laparoscopic surgery） END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=3 article-no= start-page=223 end-page=226 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case of microscopic low-grade appendiceal mucinous neoplasm complicated with appendicitis resected by reduced-port laparoscopic surgery kn-title=Reduced Port Surgeryで切除した高度炎症を伴う虫垂中に発見された潜在性虫垂粘液嚢胞腺腫の１例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Appendicitis is a benign disease for which surgical treatment is widely provided. The complication of neoplastic lesions may be discovered only after resection. However, in some cases, specimens are not submitted to histopathological examination in Japan because of an extreme deficiency of pathologists. We report our experience with one patient who experienced the complication of latent low-grade appendiceal mucinous neoplasm (LAMN) after surgery for appendicitis. Our patient was an 85-year-old woman. Conservative treatment failed to relieve fever and lower abdominal pain and it was decided to treat her surgically. Abdominal computed tomography (CT) showed appendicitis with severe inflammation and suspected adhesion. We decided to explore the abdominal cavity using a reduced-port laparoscopic approach. We found no mucous debouchment or clear tumors in the specimen. Histopathological findings indicated the coexistence of appendicitis and LAMN. At one year and a half after surgery, there was no evidence of the development of pseudomyxoma peritonei. In appendectomy, it is thought that careful perioperative treatment and a postoperative pathological search are important when there are no preoperative findings suggesting a neoplastic lesion. en-copyright= kn-copyright= en-aut-name=SuzukiHiromitsu en-aut-sei=Suzuki en-aut-mei=Hiromitsu kn-aut-name=鈴木宏光 kn-aut-sei=鈴木 kn-aut-mei=宏光 aut-affil-num=1 ORCID= en-aut-name=KimuraKouji en-aut-sei=Kimura en-aut-mei=Kouji kn-aut-name=木村紘爾 kn-aut-sei=木村 kn-aut-mei=紘爾 aut-affil-num=2 ORCID= en-aut-name=KinoshitaSigeki en-aut-sei=Kinoshita en-aut-mei=Sigeki kn-aut-name=木下茂喜 kn-aut-sei=木下 kn-aut-mei=茂喜 aut-affil-num=3 ORCID= en-aut-name=OkanoKazuo en-aut-sei=Okano en-aut-mei=Kazuo kn-aut-name=岡野和雄 kn-aut-sei=岡野 kn-aut-mei=和雄 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=倉敷市立児島市民病院　外科 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　呼吸器・乳腺内分泌外科学 affil-num=3 en-affil= kn-affil=倉敷市立児島市民病院　外科 affil-num=4 en-affil= kn-affil=倉敷市立児島市民病院　外科 en-keyword=虫垂炎（appendicitis） kn-keyword=虫垂炎（appendicitis） en-keyword=減孔式腹腔鏡手術（reduced-port laparoscopic surgery） kn-keyword=減孔式腹腔鏡手術（reduced-port laparoscopic surgery） en-keyword=虫垂粘液嚢胞腺腫（low-grade appendiceal mucinous neoplasm (LAMN)） kn-keyword=虫垂粘液嚢胞腺腫（low-grade appendiceal mucinous neoplasm (LAMN)） en-keyword=腹膜偽粘液腫（pseudomyxoma peritonei） kn-keyword=腹膜偽粘液腫（pseudomyxoma peritonei） en-keyword=腹腔鏡下虫垂切除術（laparoscopic appendectomy） kn-keyword=腹腔鏡下虫垂切除術（laparoscopic appendectomy） END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=9 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Seed Maturation Regulators Are Related to the Control of Seed Dormancy in Wheat (Triticum aestivum L.) en-subtitle= kn-subtitle= en-abstract= kn-abstract=In Arabidopsis, the regulation network of the seed maturation program controls the induction of seed dormancy. Wheat EST sequences showing homology with the master regulators of seed maturation, LEAFY COTYLEDON1 (LEC1), LEC2 and FUSCA3 (FUS3), were searched from databases and designated respectively as TaL1L (LEC1-LIKE), TaL2L (LEC2-LIKE), and TaFUS3. TaL1LA, TaL2LA and TaFUS3 mainly expressed in seeds or embryos, with the expression limited to the early stages of seed development. Results show that tissue-specific and developmental-stage-dependent expressions are similar to those of seed maturation regulators in Arabidopsis. In wheat cultivars, the expression level of TaL1LA is correlated significantly with the germination index (GI) of whole seeds at 40 days after pollination (DAP) (r = -0.83**). Expression levels of TaFUS3 and TaL2LA are significantly correlated respectively with GIs at 40 DAP and 50 DAP, except for dormant cultivars. No correlation was found between the expression level of TaVP1, orthologue of ABA INSENSITIVE3 (ABI3), and seed dormancy. DELAY OF GERMINATION1 (DOG1) was identified as a quantitative trait locus (QTL) for the regulation of seed dormancy in Arabidopsis. Its promoter has RY motif, which is a target sequence of LEC2. Significant correlation was found between the expression of TaDOG1 and seed dormancy except for dormant cultivars. These results indicate that TaL1LA, TaL2LA, and TaFUS3 are wheat orthologues of seed maturation regulators. The expressions of these genes affect the level of seed dormancy. Furthermore, the pathways, which involve seed maturation regulators and TaDOG1, are important for regulating seed dormancy in wheat. en-copyright= kn-copyright= en-aut-name=RikiishiKazuhide en-aut-sei=Rikiishi en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaekawaMasahiko en-aut-sei=Maekawa en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Inst Plant Sci & Resources affil-num=2 en-affil= kn-affil=Okayama Univ, Inst Plant Sci & Resources END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue= article-no= start-page=50 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Review of Studies on Japanese Quails with Grants-in-Aid for Scientific Research kn-title=科学研究費補助金によるウズラの研究課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Japanese quails are widely used for experiments are models of birds, such as chickens, and are becoming increasingly important in research fields today. Their experimental usefulness was initially reported in an international journal for academic research by Padgett et al. and Wilson et al. in 1959, and, since then, a large number of researchers in- and outside Japan have conducted surveys and studies to examine their characteristics. In Japan, the first study on Japanese quails with a Grant-in-Aid for Scientific Research was conducted in 1966, followed by a large number of studies examining them. This grant program aims to support original and pioneering research activities, and is also expected to promote studies on Japanese quails in a wide range of research fields, leading to the advancement of all areas. This paper reviews previous studies on Japanese quails, conducted within the 48-year period between 1966 and 2013. They were searched for using the Database of Grants-in-Aid for Scientific Research KAKEN, excluding some research subjects, and are listed chronologically by keyword. Those comparing Japanese quails with other animals or using them as part of the study are also included. en-copyright= kn-copyright= en-aut-name=SatoKatsunori en-aut-sei=Sato en-aut-mei=Katsunori kn-aut-name=佐藤勝紀 kn-aut-sei=佐藤 kn-aut-mei=勝紀 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学農学部 END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=454 sequencing of pooled BAC clones on chromosome 3H of barley en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Genome sequencing of barley has been delayed due to its large genome size (ca. 5,000Mbp). Among the fast sequencing systems, 454 liquid phase pyrosequencing provides the longest reads and is the most promising method for BAC clones. Here we report the results of pooled sequencing of BAC clones selected with ESTs genetically mapped to chromosome 3H. Results: We sequenced pooled barley BAC clones using a 454 parallel genome sequencer. A PCR screening system based on primer sets derived from genetically mapped ESTs on chromosome 3H was used for clone selection in a BAC library developed from cultivar "Haruna Nijo". The DNA samples of 10 or 20 BAC clones were pooled and used for shotgun library development. The homology between contig sequences generated in each pooled library and mapped EST sequences was studied. The number of contigs assigned on chromosome 3H was 372. Their lengths ranged from 1,230 bp to 58,322 bp with an average 14,891 bp. Of these contigs, 240 showed homology and colinearity with the genome sequence of rice chromosome 1. A contig annotation browser supplemented with query search by unique sequence or genetic map position was developed. The identified contigs can be annotated with barley cDNAs and reference sequences on the browser. Homology analysis of these contigs with rice genes indicated that 1,239 rice genes can be assigned to barley contigs by the simple comparison of sequence lengths in both species. Of these genes, 492 are assigned to rice chromosome 1. Conclusions: We demonstrate the efficiency of sequencing gene rich regions from barley chromosome 3H, with special reference to syntenic relationships with rice chromosome 1. en-copyright= kn-copyright= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MotoiYuka en-aut-sei=Motoi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamajiNami en-aut-sei=Yamaji en-aut-mei=Nami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaHideya en-aut-sei=Yoshida en-aut-mei=Hideya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Inst Plant Sci & Resources affil-num=2 en-affil= kn-affil=Okayama Univ, Inst Plant Sci & Resources affil-num=3 en-affil= kn-affil=Okayama Univ, Inst Plant Sci & Resources affil-num=4 en-affil= kn-affil=Okayama Univ, Inst Plant Sci & Resources END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue= article-no= start-page=D26 end-page=D32 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=NBRP databases: databases of biological resources in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The National BioResource Project (NBRP) is a Japanese project that aims to establish a system for collecting, preserving and providing bioresources for use as experimental materials for life science research. It is promoted by 27 core resource facilities, each concerned with a particular group of organisms, and by one information center. The NBRP database is a product of this project. Thirty databases and an integrated database-retrieval system (BioResource World: BRW) have been created and made available through the NBRP home page (http://www.nbrp.jp). The 30 independent databases have individual features which directly reflect the data maintained by each resource facility. The BRW is designed for users who need to search across several resources without moving from one database to another. BRW provides access to a collection of 4.5-million records on bioresources including wild species, inbred lines, mutants, genetically engineered lines, DNA clones and so on. BRW supports summary browsing, keyword searching, and searching by DNA sequences or gene ontology. The results of searches provide links to online requests for distribution of research materials. A circulation system allows users to submit details of papers published on research conducted using NBRP resources. en-copyright= kn-copyright= en-aut-name=YamazakiYukiko en-aut-sei=Yamazaki

Part of jhp0917-jhp0918 was sequenced to search for the C/T insertion that characterizes dupA and the levels of dupA transcripts were also assessed. The PCR and dot-blot results indicated the presence of jhp0917 and jhp0918 in 37.3% (31/83) and 12.2% (7/57) of H. pylori strains isolated from DU and NUD patients, respectively. Sequencing analysis showed insertion of a C at nt 1386 in the 3' region of jhp0917, forming the dupA gene in 35 strains. RT-PCR analysis detected the dupA transcript in 28 of these 35 strains. The expression level of the dupA transcript varied from strain to strain, as shown by real-time PCR. The results demonstrated that analysis based on PCR only for dupA may produce an erroneous interpretation. The prevalence of dupA was significantly greater among strains isolated from patients with DU than from patients with NUD in this population (P=0.001, odds ratio=4.26, confidence interval=1.60-11.74). Based on these findings, dupA can be considered a biomarker for DU patients in India. The reported discrepancies for this putative virulence marker in different populations may be due to the genome plasticity of H. pylori. en-copyright= kn-copyright= en-aut-name=AlamJawed en-aut-sei=Alam en-aut-mei=Jawed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaitiSankar en-aut-sei=Maiti en-aut-mei=Sankar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GhoshPrachetash en-aut-sei=Ghosh en-aut-mei=Prachetash kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DeRonita en-aut-sei=De en-aut-mei=Ronita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChowdhuryAbhijit en-aut-sei=Chowdhury en-aut-mei=Abhijit kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DasSuryasnata en-aut-sei=Das en-aut-mei=Suryasnata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MacadenRagini en-aut-sei=Macaden en-aut-mei=Ragini kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DevarbhaviHarshad en-aut-sei=Devarbhavi en-aut-mei=Harshad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=RamamurthyT. en-aut-sei=Ramamurthy en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=2 en-affil= kn-affil=IISER affil-num=3 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=4 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=5 en-affil= kn-affil=Inst Post Grad Med Educ & Res, Sch Digest & Liver Dis affil-num=6 en-affil= kn-affil=St Johns Med Coll Hosp affil-num=7 en-affil= kn-affil=St Johns Med Coll Hosp affil-num=8 en-affil= kn-affil=St Johns Med Coll Hosp affil-num=9 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=10 en-affil= kn-affil=Natl Inst Cholera & Enter Dis END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=390 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Construction of Argument Structure Analyzer Toward Searching Same Situations and Actions kn-title=類似した動作や状況を検索するための意味役割及び動詞語義付与システムの構築(第1回集合知シンポジウム〜言語処理が紡ぎ出す未来〜) en-subtitle= kn-subtitle= en-abstract=This manuscript proposes an argument structure analyzer that can identify verb meanings and semantic roles of their arguments from not only for sentences but compound nouns. The motivation of development of this analyzer is we need a tool to find the same or quasi-same situations, actions and changes in events. For this purpose various levels of paraphrases should be identified taking into account context, however, the proposed analyzer focus on providing lexicon-based paraphrasable relations i.e., matching "employ/use/utilize these tools" and "employment of these tools''. In this paper we clarify how we construct the modules of the analyzer, i.e., identification of idioms, deverbal-noun-argument identification in compound nouns, identification of content verbs, and identification of predicate verb semantics and their semantic roles on the basis of example based matching. The base data of verb meanings we use is a Japanese Verb Thesaurus build in our previous work and freely distributed. kn-abstract=本研究では類似した動作や状態を検索するための基礎技術として,動作表現の類似関係を付与する項構造付与システムを構築している.項構造とは動詞と名詞の係り関係まで含めて動作の共通部分を記述するもので,例えば「XがYを逮捕する」「Yを捕まえる」には概念を共通していることを示す.本研究ではすでに,4425語(7473語義)の動詞に対して動詞間の項構造関係をシソーラス形式で整理して公開している.そこでこのオントロジーを基に規則ベースの項構造付与システムの構築を行った.本報告では項構造付与に必要なサブタスクとして,慣用句同定,複合名詞内係関係同定,主動詞探索を取り上げ事例による語義決定法について述べる.また,現状での語義付与精度について簡単な評価実験を行う. en-copyright= kn-copyright= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name=竹内孔一 kn-aut-sei=竹内 kn-aut-mei=孔一 aut-affil-num=1 ORCID= en-aut-name=TsuchiyamaSuguru en-aut-sei=Tsuchiyama en-aut-mei=Suguru kn-aut-name=土山傑 kn-aut-sei=土山 kn-aut-mei=傑 aut-affil-num=2 ORCID= en-aut-name=MoriyaMasato en-aut-sei=Moriya en-aut-mei=Masato kn-aut-name=守屋将人 kn-aut-sei=守屋 kn-aut-mei=将人 aut-affil-num=3 ORCID= en-aut-name=MoriyasuYuuki en-aut-sei=Moriyasu en-aut-mei=Yuuki kn-aut-name=森安祐樹 kn-aut-sei=森安 kn-aut-mei=祐樹 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学工学部情報工学科 affil-num=3 en-affil= kn-affil=岡山大学工学部情報工学科 affil-num=4 en-affil= kn-affil=岡山大学工学部情報工学科 END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue=1 article-no= start-page=77 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Genetic polymorphisms as susceptibility factors for drug response kn-title=遺伝子多型と薬剤感受性 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KurodaSatoshi en-aut-sei=Kuroda en-aut-mei=Satoshi kn-aut-name=黒田智 kn-aut-sei=黒田 kn-aut-mei=智 aut-affil-num=1 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name=千堂年昭 kn-aut-sei=千堂 kn-aut-mei=年昭 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院　薬剤部 affil-num=2 en-affil= kn-affil=岡山大学病院　薬剤部 END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=4 article-no= start-page=448 end-page=457 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genome-wide deficiency mapping of the regions responsible for temporal canalization of the developmental processes of Drosophila melanogaster en-subtitle= kn-subtitle= en-abstract= kn-abstract=Developmental processes of organisms are programed to proceed in a finely regulated manner and finish within a certain period of time depending on the ambient environmental conditions. Therefore, variation in the developmental period under controlled genetic and environmental conditions indicates innate instability of the developmental process. In this study, we aimed to determine whether a molecular machinery exists that regulates the canalization of the developmental period and, if so, to test whether the same mechanism also stabilizes a morphological trait. To search for regions that influence the instability of the developmental period, we conducted genome-wide deficiency mapping with 441 isogenic deficiency strains covering 65.5% of the Drosophila melanogaster genome. We found that 11 independent deficiencies significantly increased the instability of the developmental period and 5 of these also significantly increased the fluctuating asymmetry of wing shape although there was no significant correlation between the instabilities of developmental period and wing shape in general. These results suggest that canalization processes of the developmental period and morphological traits are at least partially independent. Our findings emphasize the potential importance of temporal variation in development as an indicator of developmental stability and canalization and provide a novel perspective for understanding the regulation of phenotypic variability. en-copyright= kn-copyright= en-aut-name=TakahashiKazuo H. en-aut-sei=Takahashi en-aut-mei=Kazuo H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaYasukazu en-aut-sei=Okada en-aut-mei=Yasukazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TeramuraKouhei en-aut-sei=Teramura en-aut-mei=Kouhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Research Core for Interdisciplinary Sciences, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=developmental period kn-keyword=developmental period en-keyword=developmental stability kn-keyword=developmental stability en-keyword=Drosophila melanogaster kn-keyword=Drosophila melanogaster en-keyword=wing shape kn-keyword=wing shape END start-ver=1.4 cd-journal=joma no-vol=2006 cd-vols= no-issue=94 article-no= start-page=35 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Web Search Result Clustering Based on Structure of Compound Nouns kn-title=複合名詞に着目したWeb検索結果のクラスタリング en-subtitle= kn-subtitle= en-abstract=In this paper, we propose a aclustering method based on structure of compound nouns. Japanese compound nouns usually provide concrete concepts, thus we can assume that compound nouns must be a good clue to index documents for Web document clustering. The other benefit of using compound nouns is their compositional structure that can ve divided into sub concepts. This indicates that we can construct hierarchical Web document clustering based on their strcture. From the practical experiments of constructing hierarchical clusters on the results of a Web search engine, we succeeded in showing that the clearly lusterized web documents with understandable hierarchical indexes of compound nouns. kn-abstract=本稿では複合名詞に着目したWeb検索結果のクラスタリング手法を提案する．本手法では検索結果のタイトルと要約を利用し，階層的で一つの検索結果が複数のクラスタに含まれることを認めるクラスタリングを行う．本手法は次の２つの仮説に基づいている．1)複合名詞は固有の概念を表すため，文書を特徴付けやすい．2)複合名詞間の語構成関係を利用して，部分複合による類概念，および上位下位関係のクラスラベルを作成することで見通しの良いＷｅｂ文書の分類ができる．実験の結果，複合名詞の構造は分かりやすいクラスタ構造の形成に利用でき，また自然なラベル付けに有効であった．このことから，複合名詞は検索結果全体を見渡すためのよいインデックスであると言える． en-copyright= kn-copyright= en-aut-name=HiraoKazuki en-aut-sei=Hirao en-aut-mei=Kazuki kn-aut-name=平尾一樹 kn-aut-sei=平尾 kn-aut-mei=一樹 aut-affil-num=1 ORCID= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name=竹内孔一 kn-aut-sei=竹内 kn-aut-mei=孔一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=2 article-no= start-page=15 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=200203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Study on the Planning and Scheduling of Production System Considering Demand Changes en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we studied a planning and scheduling of production system considering demand changes. In the proposed system, planning part determines lot-size and amount of jobs in production. On the other hand, scheduling part determines the production sequence of jobs. In order to treat with the demand changes, both planning and scheduling should work well simultaneously. In the proposed system, preset and real time production control system is newly constructed from the view point of adaptive control. In the system, production planning is modified when the difference between production amount and demand becomes large. Moreover, production schedule is regenerated when the determined schedule is deviated from the prospected one. The scheduling system is characterized as the autonomous decentralized optimization system where each job works as agent and agent searches its appropriate starting time of processing. The effectiveness of the proposed system is confirmed by numerical examples. en-copyright= kn-copyright= en-aut-name=OhtaniRyuji en-aut-sei=Ohtani en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonishiMasami en-aut-sei=Konishi en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiJun en-aut-sei=Imai en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Electrical and Electronic Engineering, Okayama University affil-num=2 en-affil= kn-affil=Department of Electrical and Electronic Engineering, Okayama University affil-num=3 en-affil= kn-affil=Department of Electrical and Electronic Engineering, Okayama University affil-num=4 en-affil= kn-affil=Department of Electrical and Electronic Engineering, Okayama University END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=1 article-no= start-page=107 end-page=116 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=200112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Automatic Detection of Circular Objects by Ellipse Growing en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a new method for automatically detecting circular objects in images: we detect an osculating circle to an elliptic arc using a Hough transform, iteratively deforming it into an ellipse, removing outlier pixels, and searching for a separate edge.

Our strategy is to impose various local and non-local constraints as "soft" constraints by introducing their "confidence" measures via "mean-field approximations". The computation is a cascade of evaluating the confidence values and sorting according to them. In the end, we impose the "hard" epipolar constraint by RANSAC. We also introduce a model selection procedure to test if the image mapping can be regarded as a homography. We demonstrate the effectiveness of our method by real image examples. en-copyright= kn-copyright= en-aut-name=KanazawaYasushi en-aut-sei=Kanazawa en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanataniKenichi en-aut-sei=Kanatani en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Knowledge-based Information Engineering Toyohashi University of Technology affil-num=2 en-affil= kn-affil=Department of Information Technology Okayama University END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=7 article-no= start-page=1299 end-page=1319 dt-received= dt-revised= dt-accepted= dt-pub-year=1954 dt-pub=19540731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental Studies on Hypertrophy of Prostate as well as on Kidney Function II Chapter.

After having prepared some extracts, made respectively from a dog's normal prostate, moderately hypertrophied prostate in mixed form, as well as from highly glandular hypertrophied prostate, both of dog, injected them subcutaneously in a dog, in doses of 5-2cc per day, for about 14-16 weeks successively, and examined such as general view, changes occurred to Rest-N, Cl, Ur as well as Ur within blood; moreover, employing some fluid test, and in view to urinal symptoms, has endeavoured to find out those changes that have occurred in kidney functions. 2. Among the cases in which extracts out of dog's normal prostate gland were administered, no important perpetual changes could be recognized. 3. In the case where extracts from the moderate hypertrophied prostate in mixed form were administered, (2nd case), fluid test proved to be utter failure, submitted no results, but probably this may be due to some individual quality of test animals, in the urin of which one could always detect certain spermo. However, during ten-weeks course allotted to this case, loss of body weight, (about minus 7.8%), together with a regular gradual increase on the part of Rest-N, Cl, Ur and Ur in blood, could be detected, whose final values all have exceeded normal area. 4. Among cases in which highly glandular hypertrophied gland were administered, first such symptoms as thirst, then came loss of spirit, followed by anxiety as well as depression, which ended in the appearance of edems in the back limb at the middle of, 11th week; growing higher and higher. 5. The increase of Rest-N, Cl, Ur and Ur within blood has also been clearly seen; above all, the last-mentioned one showed a special increase. 6. Moreover, in fluid test, a clear obstruction of concentration ability could be seen. 7. As for urin, here also appeared changes that have accompanied to general view and fluid test. 8. The dog which supplied the moderately hypertrophied prostate in mixed form employed in 2nd case (7 years), has been verified diagnosed owing to histological search of its kidney, that has given rise to a distinct Nephrose. 9. From the above results obtained by experiments, it is thought most proper for us to consider that the kidney trouble discovered in hypertrophy of prostate is apt to be accompanied with certain poisonous changes of kidney parenchyma, which may be ascribed to the poisoned substance due to hypertrophy of prostate. en-copyright= kn-copyright= en-aut-name=OhtoShigemichi en-aut-sei=Ohto en-aut-mei=Shigemichi kn-aut-name=大藤重道 kn-aut-sei=大藤 kn-aut-mei=重道 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部皮膚科泌尿器科教室 END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=5 article-no= start-page=905 end-page=908 dt-received= dt-revised= dt-accepted= dt-pub-year=1955 dt-pub=19550531 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Acatalasemia Part III.

Nissan has been in restructuring under the French managers dispatched by Renault. Suzuki and Isuzu began to reinforce their cooperation with GM, whereas Fuji Heavy Industry (Subaru) and Mitsubishi are searching for their Western partners. It is only Toyota and Honda that seem to be able to compete by themselves on globalized automobile markets. Irony of the history, because until the end of the 1980s all Japanese carmakers were regarded as the most competitive companies of the world by incarnating the 'Lean Production' model whose basic model is the Toyota Production System. This stereotype has to be dismissed, because they have been having neither the same management nor the same strategy. This paper then tries to show the history of Japanese automobile industry from its very beginning to mid-1990 when the majority of carmakers are facing a crisis. In doing so, it presents the specifie characteristics of Toyota by placing it in the historical perspective. en-copyright= kn-copyright= en-aut-name=ShimizuKoichi en-aut-sei=Shimizu en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=4 article-no= start-page=65 end-page=100 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20010310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Evolution of Industries and the Public Policies for the Creation of New Business kn-title=産業進化と創業･成長支援策 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the latter half in 1990's, the extensive public policies for promoting newly establishment of the enterprise (for example, "Law for facilitating the creation of New Business" enforced in 1999) were introduced in Japan. In this paper, I would like to search the theoretical background of such policy as the policy for promoting evolution of industry that the innovative activities were accompanied by newly establishment and discontinuance ofbusiness of the enterprise. To begin with, I carried out the fact finding on the relation between newly establishment and discontinuance of business using the data of "The 1999 Establishment and Enterprise Census." And I verified some hypotheses on the evolution of industries which Acs and Audretsch (1991) and Audretsch (1995) presented and tried the reexamination of these hypotheses. I set the increasing rate of newly establishment (the number of employee base) and the increasing rate of discontinuance of business (the number of employee base) during 1996-1999 period as main variables. I carried out the regression analysis on manufacturing industries and service industries (industrial classification of 2 and 3 digits), and confirmed that there was the positive correlation between the increasing rate of newly establishment and the increasing rate of discontinuance of business. I examined the ratio of increasing rate of discontinuance of business and increasing rate of newly establishment (D / E ratio) on enterprise scale (by the number of employee base) and industrial sector (industrial classification of 2 digits). As the result, I confirmed that the D / E ratio described the V-shaped curve with the extension of enterprise scale in many industrial sectors. I consider that the base point of this V-shaped curve shows minimum efficient scale. I confirmed that there was the positive correlation between this minimum efficient scale (D / E ratio at V-shaped base point) and employment increasing rate of the industrial sector. Based on these results of analysis, I describe some policy implications on the public policies for the newly establishment of enterprises and the initial support and growth support for the newly-established and smallscale enterprises. en-copyright= kn-copyright= en-aut-name=NittaMitsllshige en-aut-sei=Nitta en-aut-mei=Mitsllshige kn-aut-name=新田光重 kn-aut-sei=新田 kn-aut-mei=光重 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=城西大学経済学部 END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=11-1 article-no= start-page=7291 end-page=7304 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=19591020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Electrolytes in Blood and Skin in Skin Diseases Part 1.

The myelogram showed a parallel change to the peripheral hemogram in severe cases with remarkable leukocytosis and neutrocytosis on the peripheral blood picture. 3. The monocytosis and the appearance of plasma cells and plasmoid cells in mild cases had no direct relation to the bone marrow and it was thought that the origin of this reaction should be searched on other system, except bone marrow. 4.

In mammals, toxic electrolytes of endogenous and exogenous origin are excreted through the urine and bile. Before excretion, these compounds cross numerous cellular membranes in a transporter-mediated manner. However, the protein transporters involved in the final excretion step are poorly understood. Here, we show that MATE1, a human and mouse orthologue of the multidrug and toxin extrusion (MATE) family conferring multidrug resistance on bacteria, is primarily expressed in the kidney and liver, where it is localized to the luminal membranes of the urinary tubules and bile canaliculi. When expressed in HEK293 cells, MATE1 mediates H+-coupled electroneutral exchange of tetraethylammonium (TEA) and 1-methyl-4-phenylpyridinium (MPP). Its substrate specificity is similar to those of renal and hepatic H+-coupled organic cations (OCs) export. Thus, MATE1 appears to be the long searched for polyspecific OC exporter that directly transports toxic OCs into urine and bile.

We present a quantitative study on sensitivities to the top-decay anomalous couplings, taking into account realistic experimental conditions expected at Tevatron and LHC. A double angular distribution of W and charged lepton in the top-decay is analyzed, using t<(t)<($)over bar> events in the leptons+jets channel. In order to improve sensitivities to the anomalous couplings, we apply two techniques: (i) We use a likelihood fitting method for full kinematical reconstruction of each top event. (ii) We develop a new effective spin reconstruction method for leptonically-decayed top quarks; this method does not require spin information of the antitop side. For simplicity, we neglect couplings of right-handed bottom quark as well as CP violating couplings. The 95% C.L. estimated bound on a ratio of anomalous couplings reads -0.81 < f(2)/f(1)<-0.70, -0.12 < f(2)/f(1)< 0.14 using 1000 reconstructed top events at Tevatron, while -0.74 < f(2)/f(1)<-0.72, -0.01 < f(2)/f(1)< 0.01 is expected with 100 k reconstructed top events at LHC, where only statistical errors are taken into account. A two-fold ambiguity in the allowed range remains when the number of events exceeds a few hundred.

In order to improve TCP performance, a method using a PEP (Perfonnance Enhancing Proxy) is proposed. The PEP operates on a router along a TCP connection. When a data packet arrives at the PEP, it forwards the packet to the destination host, transmits the corresponding ACK (premature ACK) to the source host in behalf of the destination host and stores the copy of the packet into its own buffer (PEP buffer) in case of the retransmission of the packet. In this paper, under the strategy which keeps the number of packets in the PEP buffer for which premature ACKs have been returned being less than or equal to a fixed threshold value (watermark value), we investigate the relation between the watermark value and the maximum throughput. Extensive simulation runs show that the simulation results are roughly classified into two cases. One case is that the maximum throughput becomes larger for larger watermark value and becomes a constant value when the watermark value is over a value. The other case is that though the maximum throughput becomes larger for lager watermark value in the same way, it reversely decreases when the watermark value is over a value. We also show that the latter (former) case is easier to occur as the propagation delay in the input side network ofthe PEP becomes smaller (larger) and the propagation delay in the output side network of the PEP becomes larger (smaller) and the PEP buffer capacity becomes smaller (larger).

The isochronous channel reuse problem (ICRP) has been studied for the efficient use of DQDB. Given a set of established connections and a set of connection requests, the goal of ICRP is to maximize the number of satisfied requests by finding a proper channel assignment, such that no established connection is not only reassigned a channel, but also any pair of active connections does not interfere each other. We propose a minimal-state processing search algorithm for ICRP (MIPS/sub -/ICRP). The simulation results show that MIPS/sub -/ICRP always provides near-optimum solutions. en-copyright= kn-copyright= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuganoAyako en-aut-sei=Sugano en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HigashinoTeruo en-aut-sei=Higashino en-aut-mei=Teruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Communication Network Engineering, Okayama University affil-num=2 en-affil= kn-affil=Department of Communication Network Engineering, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Information Science and Technology, Osaka University en-keyword=IEEE standards kn-keyword=IEEE standards en-keyword=access protocols kn-keyword=access protocols en-keyword=channel allocation kn-keyword=channel allocation en-keyword=metropolitan area networks kn-keyword=metropolitan area networks en-keyword=performance evaluation kn-keyword=performance evaluation en-keyword=telecommunication standards kn-keyword=telecommunication standards END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=304 end-page=307 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20063 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A LECCS model parameter optimization algorithm for EMC designs of IC/LSI systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=

<p>In this paper, we propose a parameter optimization algorithm for EMC macro-modeling of IC/LSI power currents called the LECCS (linear equivalent circuit and current source) model. The unnecessary electro-magnetic wave from a digital electronics device may cause the electromagnetic interference (EMI) to other apparatus. Thus, its reduction has been regarded as one of the highest priority issues in digital electronics device designs. In order to accurately simulate high-frequency currents from power-supply sources that are the primary sources of EMI, the LECCS model has been proposed as a linear macromodel of a power-supply circuit. A LECCS model consists of multiple RLC-series circuits in parallel to represent the equivalent circuit between the voltage source and the ground. Given a set of measured impedances at various frequencies, our proposed algorithm first finds the number of RLC-series circuits corresponding to the number of valleys. Then, it searches optimal values of RLC parameters by a local search method. The effectiveness of our algorithm is verified through applications to a real system, where the accuracy and the required processing time by our algorithm are compared with the conventional method.</p>

As one of mobile agent applications, many systems which provide continuous service for users moving on a network have been proposed. In these systems, because a movement of mobile agents is performed after a user movement, users must wait for arrival of mobile agents. To reduce users' waiting time, we propose a fundamental framework for mobile agent systems where an agent can move precedently before a user movement. In our frame-work, it is assumed that computers are connected on a network and users with rewritable devices move on the network. The framework supports precedent movement ofmobile agents based on prediction using movement history of users. Because the prediction may be wrong, the framework also provides the following movement of mobile agents. Moreover, the framework provides a recovery method of mobile agents in service in case that mobile agents disappear due to problems such as their bugs. Because we provide some APIs, via which various functions of our framework are accessed, developers of mobile agent systems can easily use our framework using the APIs. We implemented an experimental agent system using the APIs and confirmed that the framework perforned correctly using the experimental system.

In the proposed control method, the effect of a magnetic saturation and an armature reaction are taken into account by representing the coefficients of an electromotive force and a torque as a function of the field current, the armature current and the revolving speed. The current commands at which the loss of the motor drive system becomes a minimum are calculated as an optimal problem. The proposed control technique of a motor is implemented on the microprocessor-based control system. The effect of the consideration of the magnetic saturation and the armature reaction on the produced torque and the minimisation of the loss are discussed analytically and experimentally

Power bus resonance characteristics of a gapped power-plane with a slit and a split power-plane with a gap were studied, using a fast algorithm based on a full cavity-mode resonator model and the segmentation method. Inductance and capacitance models were used to account for a field coupling along the slit and across the gap, respectively. Good agreements between the calculated and measured results were found to demonstrate the effectiveness and accuracy of our fast algorithm and the segmentation method, as well as the inductance model for the slit and the capacitance model for the gap.

In this paper, we propose a parameter optimization algorithm for EMC macro-modeling of IC/LSI power currents called the LECCS (linear equivalent circuit and current source) model. The unnecessary electro-magnetic wave from a digital electronics device may cause the electromagnetic interference (EMI) to other apparatus. Thus, its reduction has been regarded as one of the highest priority issues in digital electronics device designs. In order to accurately simulate high-frequency currents from power-supply sources that are the primary sources of EMI, the LECCS model has been proposed as a linear macromodel of a power-supply circuit. A LECCS model consists of multiple RLC-series circuits in parallel to represent the equivalent circuit between the voltage source and the ground. Given a set of measured impedances at various frequencies, our proposed algorithm first finds the number of RLC-series circuits corresponding to the number of valleys. Then, it searches optimal values of RLC parameters by a local search method. The effectiveness of our algorithm is verified through applications to a real system, where the accuracy and the required processing time by our algorithm are compared with the conventional method.

In the present paper, we shall investigate the conditions under which a given Riemannian space Vn can be imbedded, as a hypersurface, into a Riemannian space Vn+1 which has the following properties I) and II). I) The group of holonomy of the space with a normal projective .connexion corresponding to Vn+1 fixes a hyperquadric and Vn is its image in Vn+1 , that is, the locus of points lying on the parallel displaced hyperquadrics, regarded as points in the tangent projective spaces. If Vn+1 has the property above, there exist a scalar y such that the hypersurface is given by the relation y -= 0. II) The orthogonal trajectories of the family of the hypersurfaces on which y is constant are geodesics in Vn+1. If the group of holonomy of the space with a normal projective eonnexion corresponding to a Vn+1 fixes a hyperquadric, it is projectively equivalent to an Einstein space2 ). In the previous paper, the author have studied the problem of the same kind as this under the conditions I) and II') Vn+1 is an Einstein space. The imbedding problem of Vn into Vn+1 under the only condition I) is very complicated in structure. The purpose of the present paper is also to search for the methods dealing with the problem, as the previous one.

To demonstrate the effectiveness of the proposed method, simulations of a puddle world and experiments of a maze world have been carried out. As a result effective behaviors have been obtained quickly.

We consider a flexible autonomous system. To realize the system, we employ a hyper-redundant system (a flexible hardware system) and reinforcement learning controller "QDSEGA" (Q-learning with structuring exploration space based on genetic algorithm) which is a flexible software system. In this paper we apply QDSEGA for controlling of the hyper-redundant robot. To demonstrate the effectiveness, a task of acquisition of locomotion patterns is applied to a multi-legged formation and a snake-like formation, from which an effective locomotion is obtained.

An odometry system that mobile robot uses for positioning has cumulative error because of wheels' slippage and uneven ground. It causes a risk of collision of obstacles. Therefore, we propose a path evaluation method for a mobile robot based on a risk of collision. To evaluate a robot's path, we define an evaluation value as an integral of a risk of collision along the path. To evaluate the risk of collision at each point, we use an estimated positioning error generated in the odometry system. Using the evaluation method, the robot can plan a path based on a risk of collision, not the shortest path. We also consider sensing points planning for position adjustment of the mobile robot, based on the same approach. Some examples of path evaluation results support a validity of the proposed method.

Reinforcement learning is one of effective controller for autonomous robots. Because it does not need priori knowledge and behaviors to complete given tasks are obtained automatically be repeating trial and error. However a large number of trials are required to realize complex tasks. So the task that can be obtained using the real robot is restricted to simple ones. Considering these points, various methods that prove the learning cost of reinforcement learning have been proposed. In the method that uses priori knowledge, the methods lose the autonomy that is most important feature of reinforcement learning in applying it to the robots. In the Dyna-Q, that is one of simple and effective reinforcement learning architecture integrating online planning, a model of environment is learned from real experience and by utilizing the model to learn, the learning time is decreased. In this architecture, the autonomy is held, however the model depends on the task, so acquired knowledge of environment cannot be reused to other tasks. In the real world, human beings can learn various behaviors to complete complex tasks without priori knowledge of the tasks. We can try to realize the task in our image without moving our body. After the training in the image, by trying to the real environment, we save time to learn. It means that we have model of environment and we utilize the model to learn. We consider that the key ability that makes the learning process faster is construction of environment model and utilization of it. In this paper, we have proposed a method to obtain an environment model that is independent of the task. And by utilizing the model we have decreased learning time. We consider distributed autonomous agents, and we show that the environment model is constructed quickly by sharing the experience of each agent, even when each agent has own independent task. To demonstrate the effectiveness of the proposed method, we have applied the method to the Q-learning and simulations of a puddle world are carried out. As a result effective behaviors have been obtained quickly.

This paper applies our developed novice users oriented force feedback steering wheel interface and mouse interface to navigating a tank type rescue robot. By analyzing merits and limitation of operating each interface, we propose a combined navigation strategy by the two interfaces. The steering wheel interface consists of a force feedback steering control and a six monitors’ wall. Through this interface, users can navigate the tank robot like driving cars, while watching incoming videos. It provides a daily life operation method for novice users to navigate the tank rescue robot. The steering wheel interface is efficient in exploring open areas. For complex disaster fields, this interface requires users have skillful operation experiences, which take them more attention. The mouse-screen interface consists of a mouse and a camera’s view displayed in a computer screen. Through this interface, users can navigate the tank robot just by mouse clicking. Path planning and low-level controlling are realized by system automatically. The mouse-screen interface can realize exact navigation, especially needed in complex structures, without taking much attention. It gives users more time to care incoming information. The two interfaces can shift into each other at any time. The combined navigation strategy adopts merits of the two interfaces and compensates limitation of each of them. It provides an efficient operation method for novice users to navigate rescue robots.

Impedance control system is introduced to realize several rehabilitation modes. The validity of the proposed system is confirmed through some experiments.

The purpose of this research is to realize a small robot which can negotiate pipes whose diameter varies widely during the robot's course. A new in-pipe locomotion mechanism named "snaking drive" is proposed in this paper and its potential and fundamental characteristics are shown with experimental data of the prototype model. First, in the sections 2 to 5, the basic traveling characteristics of the snaking drive mechanism are discussed: a theoretical formula of the fundamental characteristics and control algorithm are derived, the motions of the robot are simulated on a PC, and the prototype model was designed, developed, and tested. Next, in the sections 6 and 7, additional control algorithms for the front link are derived. They are necessary for steering at T-branches and L-bends of pipes, and also for camera view stabilization. Their performances are also shown by software simulation and experiments. The prototype robots moved in pipes whose diameter varies between 55 mm to 331 mm with the maximum speed of 22 mm/s. The paper also shows that the prototype negotiates T-branches and L-bends of pipes with inspection capability through a camera mounted on the robot.

This paper applies our developed novice users oriented force feedback steering wheel interface and mouse interface to navigating a tank type rescue robot. By analyzing merits and limitation of operating each interface, we propose a combined navigation strategy by the two interfaces. The steering wheel interface consists of a force feedback steering control and a six monitors’ wall. Through this interface, users can navigate the tank robot like driving cars, while watching incoming videos. It provides a daily life operation method for novice users to navigate the tank rescue robot. The steering wheel interface is efficient in exploring open areas. For complex disaster fields, this interface requires users have skillful operation experiences, which take them more attention. The mouse-screen interface consists of a mouse and a camera’s view displayed in a computer screen. Through this interface, users can navigate the tank robot just by mouse clicking. Path planning and low-level controlling are realized by system automatically. The mouse-screen interface can realize exact navigation, especially needed in complex structures, without taking much attention. It gives users more time to care incoming information. The two interfaces can shift into each other at any time. The combined navigation strategy adopts merits of the two interfaces and compensates limitation of each of them. It provides an efficient operation method for novice users to navigate rescue robots.

Reinforcement learning is very effective for robot learning. It is because it does not need prior knowledge and has higher capability of reactive and adaptive behaviors. In our previous works, we proposed new reinforce learning algorithm: "Q-learning with dynamic structuring of exploration space based on genetic algorithm (QDSEGA)". It is designed for complicated systems with large action-state space like a robot with many redundant degrees of freedom. However the application of QDSEGA is restricted to static systems. A snake-like robot has many redundant degrees of freedom and the dynamics of the system are very important to complete the locomotion task. So application of usual reinforcement learning is very difficult. In this paper, we extend layered structure of QDSEGA so that it becomes possible to apply it to real robots that have complexities and dynamics. We apply it to acquisition of locomotion pattern of the snake-like robot and demonstrate the effectiveness and the validity of QDSEGA with the extended layered structure by simulation and experiment.

The goal of this study is to develop a mechanical system that can display elastic characteristic of an object aiming at the application in the field of virtual reality. A pneumatic parallel manipulator is introduced as a driving mechanism, which consequently brings the capability of minute force displaying property owing to the air compressibility. A compliance control system without using force/moment sensor is constructed by introducing a disturbance observer, and a compliance display scheme is proposed. The validity of the proposed scheme is verified experimentally.

The three centrally located putative accessory neurons of the muscle receptor organ (MRO) of the isopod Ligia exotica were identified to the third segmental nerve (N3) of the thoracic ganglion by backfilling with Lucifer Yellow. These neurons were then studied intracellularly and extracellularly to determine whether they suppressed the stretch-activated responses of thoracic stretch receptors. Intracellular injection of depolarizing currents into these three putative accessory neurons revealed that only neuron #3 had an inhibitory effect, suggesting that it is an inhibitory accessory neuron related to thoracic stretch receptors. We searched for the peripheral targets of neurons #1 and #2 by intracellular filling with Lucifer Yellow or by recording of junctional potentials in extensor muscles, and show that they are motor neurons that innervate the deep extensor and superficial extensor muscles, respectively.

When shipwrecks occur, the searching activities for rescue is done using an airplane. The detection of the rescue target such as life rafts depends on a visual search by human eyes. To detect a small rescue target in a wide sea area, the searching man must monitor motion sights under nasty weather. The human eyes sometimes loses its sight and the ability of detection fails owing to the long flight and the nasty weather. To support the searching activities in the case of a marine casualty, we propose motion image processing techniques using the improved S/N ratio and dynamic range of the image data of the rescue target in the motion images under bad conditions

This paper describes a non-contact optical measuring approach by which to measure the three-dimensional (3D) shape of a transparent object such as a glass panel or an acrylic plate. In conventional approaches to obtain the 3D shape of a transparent object, contact-type sensors have been widely used. However, the measurement accuracy of contact-type sensors is susceptible to the influence of various factors. In this paper, we propose a novel triangulation-based rangefinding approach that can be applied to the 3D shape of a transparent object or to an opaque object. The rangefinder is based on the fact that the light projected onto the surface of a transparent object is in part reflected by the surface, though the majority of the projected light is transmitted through the surface. From the experimental results, the proposed rangefinding approach has the advantage that it can easily measure the 3D-shape of an object if the object reflects or transmits light, depending on its location. As a result, we conclude that the proposed approach has great potential for a wide range of industrial applications.

In a current study of environmental information, it is important to detect the particular object from environmental images under various conditions for security such as navigation system of ships, bird-watching for the prevention of various damage, invaders check and human rescue in the marine casualty. This paper deals with the image processing techniques for the detection of the rescue target as a particular object from environmental images. When a marine casualty occurs the detection of the rescue target such as life rafts depends on the visual search of human eyes. It is predicted, however, that human eyes sometimes lose their sight and the ability of the detection falls owing to the long flight and a bad weather. For a practical purpose of the prompt rescue of human life, the development of the searching support system in place of human eyes is required. To realize a new type searching system for the detection of the rescue target, the development of new type image processing techniques in real time manner is important. At the first step of our study, we attempt to develop image processing techniques, in order to accurately detect the rescue target under various

An object for computer graphics application requires the following two information: the three dimensional (3D) shape and surface reflectance property of the object. We proposed a 3D shape and surface reflectance measurement system using the new sensor, which can detect the incidence position and the angle of the light simultaneously. Experimental results successfully demonstrate the efficacy of the method.

To detect a small rescue target in the wide sea, the searcher man must monitor motion sights in nasty weather.

We make a simulation experiment for detection of the rescue target from images. To get basic design data for development of the searching system in the case of a marine casualty, we propose motion image processing techniques using improved S/N ratio and dynamic range of the image data of the rescue target in the motion images under bad conditions

In the surface mount technology, Ball Grid Array (BGA) has been used in a production of PC boards, because of their excellent characters such as high density of the lead pin pitch, better lead rigidity and self-alignment during re-flow processing. This paper deals with the development of image analysis for the detection of defects at BGA solder joints in PC boards by using X-ray images. In the conventional IC boards, it is possible to detect defects of solder joints by visual inspection, because the lead of IC package is set on its outside. However, we can't detect visually defects at BGA solder joints, because they are hidden under the IC package. In a production line, the inspection of BGA in PC boards depends on the function test of electric circuits in the final process. To improve a cost performance and the reliability of PC boards, an inspection of BGA is required in the surface mount process. Types of defects at BGA solder joints are solder bridge, missing connection, solder voids, open connection and miss-registration of parts. As we can find mostly solder bridge in these defects, we pick up this to detect solder bridge in a production line. The problems of image analysis for the detection of defects at BGA solder joints are the detection accuracy and image processing time according to a line speed of production. To get design data for the development of the inspection system, which can be used easily in the surface mount process, it is important to develop image analysis techniques based on X-ray image data. At the first step of our study, we attempt to detect the characteristic of the solder bridges based on an image analysis.

A 39-year-old homosexual Japanese man was admitted to our hospital with jaundice. Laboratory tests showed an elevation of transaminase and positivity for hepatitis B surface antigen and IgM-type antibody to hepatitis B core antigen. The hepatitis B virus genotype was determined to be Ae. Furthermore, a mud-like stool with blood and mucous had sometimes been noted during the past 3 years, and amebic colitis was shown by colonofi berscopy during hospitalization. The patient was diagnosed with acute hepatitis B, concurrent with amebic colitis, and was successfully treated with lamivudine and metronidazole. In Japanese patients with acute hepatitis B virus genotype A infection, homosexual activity tends to be high. Furthermore, in Japanese homosexual men, amebiasis has been increasing. Thus, in Japanese patients with acute hepatitis B, a determination of genotype should be performed in order to investigate the route of transmission of hepatitis B virus, and a search for amebiasis should be performed in patients with acute hepatitis due to hepatitis B virus genotype A. Furthermore, education of homosexual men regarding hepatitis B virus, hepatitis B virus vaccination, and amebiasis is urgently required. en-copyright= kn-copyright= en-aut-name=MiyakeYasuhiro en-aut-sei=Miyake en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwasakiYoshiaki en-aut-sei=Iwasaki en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshikawaShin en-aut-sei=Ishikawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TatsukawaMasashi en-aut-sei=Tatsukawa en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NawaToru en-aut-sei=Nawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoJun en-aut-sei=Kato en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobashiHaruhiko en-aut-sei=Kobashi en-aut-mei=Haruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakaguchiKohsaku en-aut-sei=Sakaguchi en-aut-mei=Kohsaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShiratoriYasushi en-aut-sei=Shiratori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University affil-num=4 en-affil= kn-affil=Okayama University affil-num=5 en-affil= kn-affil=Okayama University affil-num=6 en-affil= kn-affil=Okayama University affil-num=7 en-affil= kn-affil=Okayama University affil-num=8 en-affil= kn-affil=Okayama University affil-num=9 en-affil= kn-affil=Okayama University affil-num=10 en-affil= kn-affil=Okayama University en-keyword=hepatitis B virus kn-keyword=hepatitis B virus en-keyword=genotype kn-keyword=genotype en-keyword=homosexual kn-keyword=homosexual en-keyword=amebic colitis kn-keyword=amebic colitis en-keyword=lamivudine kn-keyword=lamivudine END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=109 end-page=116 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=200306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genome-wide search for strabismus susceptibility loci. en-subtitle= kn-subtitle= en-abstract= kn-abstract=

The purpose of this study was to search for chromosomal susceptibility loci for comitant strabismus. Genomic DNA was isolated from 10mL blood taken from each member of 30 nuclear families in which 2 or more siblings are affected by either esotropia or exotropia. A genome-wide search was performed with amplification by polymerase chain reaction of 400 markers in microsatellite regions with approximately 10 cM resolution. For each locus, non-parametric affected sib-pair analysis and non-parametric linkage analysis for multiple pedigrees (Genehunter software, http://linkage.rockefeller.edu/soft/) were used to calculate multipoint lod scores and non-parametric linkage (NPL) scores, respectively. In sib-pair analysis, lod scores showed basically flat lines with several peaks of 0.25 on all chromosomes. In non-parametric linkage analysis for multiple pedigrees, NPL scores showed one peak as high as 1.34 on chromosomes 1, 2, 4, 7, 10, 15, and 16, while 2 such peaks were found on chromosomes 3, 9, 11, 12, 18, and 20. Non-parametric linkage analysis for multiple pedigrees of 30 families with comitant strabismus suggested a number of chromosomal susceptibility loci. Our ongoing study involving a larger number of families will refine the accuracy of statistical analysis to pinpoint susceptibility loci for comitant strabismus.</P>

I. Replacement of inferior vena cava with crimped woven Tetoron (polyester) grafts and those reinforced with stainless steel coil en-subtitle= kn-subtitle= en-abstract= kn-abstract=

Experimental replacement of inferior vena cava with crimped woven Tetoron arterial graft was performed in dogs. Bypass-graft to thoracic inferior vena cava was not successful in two animals. Total repacement of thoracic inferior vena cava was attempted in four animals, and thoracoabdominal long implantation to inferior vena cava through diaphragm behind liver, followed by excision of thoracic inferior vena cava between the anastomoses, was done in 12 animals. Of these 16 animals, the graft was patent or not occluded in nine at autopsy between the 30th and the 451st day after implantation. Similar thoracoabdminal implantation of a graft reinforced with a steel coil was made in seven animals. Two grafts were patent at autopsy after 37 and 251 days, respectively. Abdominal vena cava replacement with a graft reinforced with a coil was undertaken in three animals. Two grafts were patent at autopsy after 117 and 142 days, respectively. On the whole, long term survival without occlusion over 30 days was obtained in fifteen/twenty-eight animals. Aside from the instances of simple bypassgraft and obvious technical errors in early experiments, it was in fifteen/ eighteen, and the graft was completely patent in ten/eighteen animals. The failures within 30 days resulted mostly from either lung complications or technical errors, and the latter were remarkable in the thoracoabdominal group where the graft reinforced with coil was used, but the application of the coil was very effective in protecting the graft against the compression by the adjacent organs. Tissue reaction to Tetoron was not noticeable and to the silk thread it was very slight and seemed not to affect long term success. By the present method even the total replacement of theracic inferior vena cava can be performed safely under normothermia and thoracoabdominallong implantation to inferior vena cava is also possible with considerable success. In order to prepare a more suitable synthetic graft for vein, it requires further search for harder, lighter, more elastic and physicochemically more stable material. The fabric of venous graft should be preferably more porous and thinner than that of the arterial graft available at the present in order to make the organization within the shortest time possible.

I. Immunochemical analysis of membrane fractions from cancer cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=

The present investigation was conducted with the purpose to search for the specific cancer antigenicity at subcellular level, as its first object. The aim is on the immunochemical consideration and comparison of fractions such as cell homogenate, nuclei, mitochondria, microsomes, and plasma membrane etc. obtained by ultracentrifugation from cancer cells (AH 130 rat ascites hepatoma), and to compare the antigenicity of individual fractions from normal rat liver cells. 1. The highest antigenicity is found in the mitochondria in membrane systems of cancer cells. 2. The high antigenicity of mitochondria is cancer specific, and is not common to that of normal cell mitochondria. 3. The plasma membrane prepared from cancer cell nuclear fraction was a highly pure cancer cell plasma membrane. 4. As far as tested by precipitin reaction the antigenicity of the cancer cell plasma membrane is almost the same as that of normal cell plasma membrane, and it is hard to say that the antigenicity of cancer cell plasma membrane is cancer specific. Antigenicity of plasma membrane hardly diminishes at the stage of carcinogenic transformation of cells.

Using a cell line (SBC-3/ADM) of human small cell lung cancer, which is 30-fold more resistant to adriamycin than the parent cell line (SBC-3), the activity of a variety of anticancer agents was analyzed by soft agar clonogenic assay to search for a means of circumventing drug resistance. The SBC-3/ADM cells were markedly resistant to some anthracycline antibiotics in comparison with the SBC-3 cells: 28-fold for daunomycin, 26-fold for 4'-epiadriamycin, 18-fold for THP-adriamycin, and 8.4-fold for aclarubicin. However, the cells were as sensitive to mitoxantrone, one of the anthraquinone derivatives, as the parent cells. The cells were resistant to structurally or pharmacodynamically unrelated compounds such as vincristine, mitomycin C, and an active form of ifosfamide, whereas they were susceptible to cisplatin to some extent. The in vitro radiosensitivity of both cell lines was also evaluated, and they were found to be equally sensitive to X-ray. These results suggest that mitoxantrone and cisplatin may exert sufficient activity for small cell lung cancer which has acquired resistance to adriamycin, and that consolidative chest irradiation may be clinically useful after combination chemotherapy including adriamycin.

1. The results of 245 pleural biopsies perfomed in 108 patients including 219 pleural needle biopsies and 26 pleural open biopsies were reported. The method of pleural biopsy seems to be superior to any other currently available diagnostic procedures for the etiological diagnosis of pleurisy. 2. When the pleural needle biopsy is compared with the pleural open biopsy, the former method has definite advantages over the open biopsy. The pleural needle biopsy is simple, repeatable and has almost no complication. The method of pleural needle biopsy is the initial method of choice as Donohoe correctly stated and should be employed in every cases of the pleurisy to confirm the etiological diagnosis. The open biopsy should be reserved only for those cases in whom the needle biopsy had not proved satisfactory. 3. Utilizing the method of needle biopsy, the pathological diagnosis was made in 86 per cent of our cases at the initial biopsy. By repeated needle biopsies, the results have improved to 91-92 per cent. 4. Most of the failures of the pleural needle biopsy were noted at the early stage of the study due to the unfamiliarity of the biopsy technique and later due to the incooperation of the patients. 5. The presence of the free pleural fluid serves as a convenient guide for the performance of the needle biopsy but successful needle biopsy was easily done without presence of pleural fluid when there is adequate pleural thickening. 6. 63-75 per cent of our diagnosed cases were proved to have granulomatous pleuritis, 13-31 per cent non-specific pleuritis and 5.4-5.8 per cent eosinophilic pleuritis due to paragonomiasis. The distribution of this pathological diagnosis seems to reflect quite well the actual picture of incidences of pleurisy of various different etiology in young adults in Korea. 7. The relationship of the success in obtaining adequate tissue by needle biopsy and interval between onset of symptom and biopsy was discussed. It was found that the interval has no significant effect on the production of adequate tissue by needle biopsy if the time elapsed is 4 weeks or more from the onset of symptom. 8. The significance of the pathological findings of ranulomatous pleuritis at one biopsy and non-specific pleuritis at another biopsy in the same patient was discussed. It is concluded that the single finding of nonspecific pleuritis at one needle biopsy cannot rule out the presence of granulomatous pleuritis and it is recommended that pleural biopsy be repeated whenever necessary. 9. The diagnostic significance of the chemical analysis of the pleural fluid was discussed in correlation with the results of the pleural needle biopsies. It is concluded that the number of examinations are not quite sufficient to draw any definite conclusion at the present stage of our study. 10. The finding of sanguinous pleural fluid in the patient of granulomatous pleuritis is quite high (72.7 %) and it was found that the sanguinous pleural fluid was most frequently found in the patients with granulomatous pleuritis in non-cancerous age. 11. Two groups of pleurisy patients with or without parenchymal lung lesion on chest X-ray were discussed in correlation with the results of the needle biopsy. It was found that the incidence of the pathological evidence of granulomatous inflammation on the biopsy specimens in these two groups is almost the same regardless of the presence of the demonstrable parenchymal lung lesion. 12. Histopathological finding of granulomatous pleuritis was discussed in conjunction with the significance of two types of tubercles, the soft tubercles and hard tubercles. In all specimens diagnosed as granulomatous pleuritis granulomas were demonstrated ranging from large, conglomerate tubercles with central caseation or giant cells to small granulomas without central caseation or Langhans' giant cells. 13. Histopathological significance of the finding of non-specific pleuritis on the biopsy specimens was discussed and the existence of a specific entity of "non-specific pleuritis" which is equivalent to the non-specific inflammation of the pericardium. 14. Cases of pleurisy due to paragonomiasis were discussed and the need of specific attention for search of new cases was emphasized.
