1Overview of Citrin Deficiency:SLC25A13 Mutations and the Frequency显示文摘Citrin deficiency,autosomal recessive disorder,caused by mutation of SLC25A13 gene on chromosome 7q21.3 has two major phenotypes:neonatal intrahepatic cholestatic hepatitis(NICCD)and adult-onset type Ⅱ citrullinemia(CTLN2).So far,we have identified 52 SLC25A13 mutations and diagnosed the patients not only in Japan(166 CTLN2 and 238 NICCD) but also in other countries.We have detected 76 Chinese,13 Korean and 15 Vietnamese patients with the same mutations as Japanese,and 13 patients(from Israel,UK,USA or Czech)with mutations different from those found in Japanese,indicating a wide distribution of citrin deficiency.DNA diagnoses of 13 known SLC25A13 mutations revealed that the carrier frequency was high in East Asian populations:Chinese(73/4 600=1/63),Japanese(21/1 372=1/65) and Korean(25/2 690=1/108),suggesting that near by 100 000 East Asians are homozygotes.It is important to find out patients with citrin deficiency,to treat them,and to prevent onset of severe CTLN2.Keiko Kobayashi Miharu Ushtkai Yuan - Zong Song Hong - Zhi Gao Jian - Sheng Sheng Ayako Tabata Furnihiko Okumura Sayaka lkeda Takeyori Saheki 2008实用儿科临床杂志2008,23,20:26
2Decreased levels of plasma adiponectin associated with increased risk of colorectal cancer显示文摘AIM:To investigate the association between adiponectin levels and risk of colorectal adenoma and cancer (early and advanced).METHODS: A cross-sectional study in a cohort of hospital-based patients was conducted between January 2004 and March 2006 at Yamagata University Hospital. Male subjects, who had colorectal tumors detected by endoscopic examination, were enrolled according to inclusion and exclusion criteria. Based on the T factor of the TNM system, intraepithelial carcinoma and submucosally invasive carcinoma were def ined as early cancer, and invasion into the muscularis propria or deeper was defined as advanced cancer. The plasma levels of glucose, insulin, total cholesterol, triglyceride, high sensitivity C-reactive protein, insulin like growth factor (IGF)-1, IGF binding protein-3, adiponectin, leptin, and resistin were measured. Each factor level was designated low or high, and the risk of adenoma or cancer was estimated by univariate and multivariate logistic regression analysis.RESULTS: We enrolled 124 male subjects (47 with adenoma, 34 with early cancer, 17 with advanced cancer, and 26 without tumors as controls). In patients with adenoma, high triglyceride and low adiponectin were associated with a significant increase in the odds ratio (OR) by univariate analysis. Only a low adiponectin level was related to increased adenoma risk, with an adjusted OR for low level (<11 μg/mL) to high (≥11 μg/mL) of 5.762 (95% confidence interval (CI):1.683-19.739, P=0.005). In the patients with early cancer, high body mass index, high triglyceride, and low adiponectin were associated with a significant increase in OR in univariate analysis. Imultivariate analysis, only low adiponectin was significantly associated with early cancer, with an adjusted OR of 4.495 (95% CI:1.090-18.528, P=0.038). However, in patients with advanced cancer, low adiponectin was not recognized as a significant risk factor for advanced cancer.CONCLUSION: A decreased level of adiponectin is strongly associated with an increased risk of colorectal adenoma and early cancer. These data call for further investigation, including a controlled prospective study.Sayaka Otake Hiroaki Takeda Shoichiro Fujishima Tadahisa Fukui Tomohiko Orii Takeshi Sato Yu Sasaki Shoichi Nishise Sumio Kawata 2010World Journal of Gastroenterology2010,16,10:14
3DNA methylation in gastric cancer, related to Helicobacter pylori and Epstein-Barr virus显示文摘Gastric cancer is a leading cause of cancer death worldwide,and significant effort has been focused on clarifying the pathology of gastric cancer.In particular,the development of genome-wide analysis tools has enabled the detection of genetic and epigenetic alterations in gastric cancer;for example,aberrant DNA methylation in gene promoter regions is thought to play a crucial role in gastric carcinogenesis.The etiological viewpoint is also essential for the study of gastric cancers,and two distinct pathogens,Helicobacter pylori(H.pylori)and Epstein-Barr virus(EBV),are known to participate in gastric carcinogenesis.Chronic inflammation of the gastric epithelium due to H.pylori infection induces aberrant polyclonal methylation that may lead to an increased risk of gastric cancer.In addition,EBV infection is known to cause extensive methylation,and EBV-positive gastric cancers display a high methylation epigenotype,in which aberrant methylation extends to not only Polycomb repressive complex(PRC)-target genes in embryonic stem cells but also non-PRC-target genes.Here,we review aberrant DNA methylation in gastric cancer and the association between methylation and infection with H.pylori and EBV.Keisuke Matsusaka Sayaka Funata Masashi Fukayama Atsushi Kaneda 2014World Journal of Gastroenterology2014,20,14:12
4Usefulness of anti-ulcer drugs for the prevention and treatment of peptic ulcers induced by low doses of aspirin显示文摘AIM:To investigate the usefulness of anti-ulcer drugs for the prevention and treatment of low-dose aspirin- induced peptic ulcer. METHODS:Upper gastrointestinal endoscopy was performed in 68 patients receiving daily low-dose aspirin(81 or 100 mg/day).The endoscopic findings were classified according to the Lanza score,and the scores were compared between groups categorized according to the concomitant use of anti-ulcer drugs and the types of drugs used.In another study,31 hemorrhagic peptic ulcer patients who had been receiving low-dose aspirin were enrolled.The patients were randomly classified into the proton pump inhibitor (PPI)-treated group and the H2 receptor antagonist (H2RA)-treated group.The administration of low-dose aspirin was continued concomitantly,and endoscopic examinations were performed 8 wk later. RESULTS:The Lanza scores(mean±SD)of the gastro-mucosal lesions were 1.0±1.9 and 1.9±2.3 in 8 and 16 patients receiving prevention therapy with a PPI and an H2RA,respectively.Both scores were significantly smaller than the scores in 34 patients who were not receiving prevention therapy(4.7±1.0)and in 10 patients receiving cytoprotective anti-ulcer drugs (4.3±1.6).In the prospective study,18 and 13 patients received a PPI and an H2RA,respectively.Endoscopic examinations revealed that the tissue in the region of the gastro-mucosal lesions had reverted to normal in all patients in the PPI-treated group and in 12 patients (92%)in the H2RA-treated group;no significant differences were observed between the groups. CONCLUSION:H2RA therapy was effective for both the prevention and treatment of low-dose aspirin- induced peptic ulcer,similar to the effects of PPIs, while cytoprotective anti-ulcer drugs were ineffective in preventing ulceration.Sayaka Nakashima Shinichi Ota Shin Arai Kiyoko Yoshino Mie Inao Keiko Ishikawa Nobuaki Nakayama Yukinori Imai Sumiko Nagoshi Satoshi Mochida 2009World Journal of Gastroenterology2009,15,6:11
5Effect of periodontal treatment on adipokines in type 2 diabetes显示文摘The association between adipokines and inflammatory periodontal diseases has been studied over the last two decades. This review was intended to explore the observation that periodontal therapy may lead to an improvement of adipokines in diabetic patients. In summary, substantial evidence suggests that diabetes is associated with increased prevalence, extent and severity of periodontitis. Numerous mechanisms have been elucidated to explain the impact of diabetes on the periodontium. However, current knowledge concerning the role of major adipokines indicates only some of their associations with the pathogenesis of periodontitis in type 2 diabetes. Conversely, treatment of periodontal disease and reduction of oral inflammation may have positive effects on the diabetic condition, although evidence for this remains somewhat equivocal.Hiroshi Ogawa Teerasak Damrongrungruang Sayaka Hori Kaname Nouno Kumiko Minagawa Misuzu Sato Hideo Miyazaki 2014World Journal of Diabetes2014,5,6:8
6Wind Tunnel Study on Wind and Turbulence Intensity Profiles in Wind Turbine Wake显示文摘In recent years, there has been a rapid development of the wind farms in Japan. It becomes very important to investigate the wind turbine arrangement in wind farm, in order that the wake of one wind turbine does not to interfere with the flow in other wind turbines. In such a case, in order to achieve the highest possible efficiency from the wind, and to install as many as possible wind turbines within a limited area, it becomes a necessity to study the mutual interference of the wake developed by wind turbines. However, there is no report related to the effect of the turbulence intensity of the external flow on the wake behind a wind turbine generated in the wind tunnel. In this paper, the measurement results of the averaged wind profile and turbulence intensity profile in the wake in the wind tunnel are shown when the turbulence intensity of the external wind was changed. The wind tunnel experiment is performed with 500mm-diameter two-bladed horizontal axis wind turbine and the wind velocity in wake is measured by an I-type hot wire probe. As a result, it is clarified that high turbulence intensities enable to the entrainment of the main flow and the wake and to recover quickly the velocity in the wake.Takao MAEDA Yasunari KAMADA Junsuke MURATA Sayaka YONEKURA Takafumi ITO Atsushi OKAWA Tetsuya KOGAKI 2011Journal of Thermal Science2011,20,2:4

8OsIDD2, a zinc finger and INDETERMINATE DOMAIN protein, regulates secondary cell wall formation显示文摘Previously, we found 123 transcription factors(TFs) as candidate regulators of secondary cell wall(SCW)formation in rice by using phylogenetic and co-expression network analyses. Among them, we examined in this work the role of OsIDD_2, a zinc finger and indeterminate domain(IDD) family TF. Its overexpressors showed dwarfism, fragile leaves, and decreased lignin content, which are typical phenotypes of plants defective in SCW formation, whereas its knockout plants showed slightly increased lignin content.The RNA-seq and quantitative reverse transcription polymerase chain reaction analyses confirmed that some lignin biosynthetic genes were downregulated in the OsIDD_2-overexpressing plants, and revealed the same case for other genes involved in cellulose synthesis and sucrose metabolism. The transient expression assay using rice protoplasts revealed that OsIDD_2 negatively regulates the transcription of genes involved in lignin biosynthesis, cinnamyl alcohol dehydrogenase 2 and 3(CAD_2 and 3), and sucrose metabolism, sucrose synthase 5(SUS_5), whereas an Alpha Screen assay, which can detect the interaction between TFs and their target DNA sequences, directly confirmed the interaction between OsIDD_2 and the target sequences located in the promoter regions of CAD_2 and CAD_3. Based on these observations, we conclude that OsIDD_2 is negatively involved in SCW formation and other biological events by downregulating its target genes.Peng Huang Hideki Yoshida Kenji Yano Shunsuke Kinoshita Kyosuke Kawai Eriko Koketsu Masako Hattori Sayaka Takehara Ji Huang Ko Hirano Reynante Lacsamana Ordonio Makoto Matsuoka Miyako Ueguchi-Tanaka 2018Journal of Integrative Plant Biology2018,60,2:3
9Perianal tuberculosis: A case report and review of the literature显示文摘Tuberculosis(TB) is still a major health problem worldwide. We present a rare case of an immunocompetent patient with perianal TB. A 38-year-old man visited a clinic with pain, swelling, and redness in the perineum. He had been persistently coughing for the past 6 mo. The abscess had formed a fistula to the perianal region, indicating perianal abscess. Mycobacterium tuberculosis was found in sputum and perianal abscess. Surgical drainage was performed, and oral anti-tuberculous drugs were administered for 6 mo. The patient's clinical course was favorable. On review of the literature on 58 cases of perianal TB, we found that the duration of persistent perianal lesion was much longer in patients without active pulmonary TB(APTB) than in those with APTB(66.4 mo vs 8.3 mo; confidence interval, 0.0760-0.9620, P = 0.0380). Thus, in cases of non-healing or recurrent perianal lesions, TB should be considered.Sayaka Tago Yuji Hirai Yusuke Ainoda Takahiro Fujita Mikio Takamori Ken Kikuchi 2015World Journal of Clinical Cases2015,3,9:3
10Binaural integration abilities in bilateral cochlear implant user显示文摘Bilateral Cochlear implants(CIs) improved speech intelligibility, speech perception in background noise, and sound localization in quiet and noisy situations. However, it is unclear whether these advantages essentially result in binaural integration of acoustic stimuli from each ear. In this study, we investigated the effectiveness of binaural integration by bilateral CIs placement using binaural hearing tests and subjective auditory perceptual assessment. A 61-year-old bilateral CIs subject underwent the following four tests: the Japanese Hearing in Noise Test(HINT-J), the dichotic listening test(DLT), the Rapidly Alternating Speech Perception(RASP) test, and subjective auditory perceptual assessment. The HINTJ score was significantly higher for bilateral CIs than for a unilateral CI. However, DLT and the RASP test revealed contradictory results.Subjective auditory perceptual assessment revealed active and bright impressions for bilateral hearing, which were also noisy and strong compared with those for unilateral hearing. The results of this study revealed that bilateral CIs improved speech perception in background noise and an improved auditory impression, although the bilateral integration abilities were not improved. This was probably because the patient was required to combine information from the two ears into a single perception in DLT and the RASP test. More longitudinal data should be collected and analyzed in future studies to evaluate the long-term effects of bilateral CIs.Chie Obuchi Masae Shiroma Sayaka Ogane Kimitaka Kaga 2015Journal of Otology2015,10,4:2

14Pleurocordyceps gen.nov.for a clade of fungi previously included in Polycephalomyces based on molecular phylogeny and morphology显示文摘Since the discovery of the Pleurocordyceps/“Polycephalomyces”clade unaffiliated with the clades of Clavicipitaceae s.str.,Ophiocordycipitaceae,and Cordycipitaceae of clavicipitaceous fungi,some taxa have been published and more fungal material relevant to the group have become available for further study.Here,a multigene phylogeny using nrSSU,nrLSU,tef1,rpb1,and rpb2 was constructed with some of the recently discovered additional taxa using maximum likelihood and Bayesian analyses(BI)to test and refine the current phylogenetic framework for Cordyceps s.lat.and other clavicipitaceous fungi.In addition to the well supported major Pleurocordyceps/“Polycephalomyces”clade revealed previously,another clade with newly added taxa referred to as“Polycephalomyces formosus-like”from Japan was found to be sister to the Pleurocordyceps/“Polycephalomyces”clade.Extensive investigation revealed that strains named“P.formosus-like”grouped in this new clade and do indeed represent the true P.formosus and that species previously included in the genus Polycephalomyces required a new generic name.Based on the phylogenetic analyses and morphological characteristics,including both sexual and asexual morphs when available,the new generic name Pleurocordyceps is introduced and relevant new combinations are made.A newly designated lectotype and a supporting epitype for P.formosus is selected and the circumscription of Polycephalomyces is discussed.Yong-Hui Wang Sayaka Ban Wen-Jing Wang Yi Li Ke Wang Paul M.Kirk Kathryn E.Bushley Cai-Hong Dong David L.Hawksworth Yi-Jian Yao 2021Journal of Systematics and Evolution2021,59,5:2
