1绕正方形排列的顺排的四个圆柱的流动研究显示文摘本文通过采用激光诱导荧关技术(LIF),对按正方形排列、边长间距比为4的顺排的四个圆柱的层流绕流进行了流动可视化研究;同时,在Re=200的情况下,对该流场进行了PIV流场测量,两种实验结果吻合良好,显示的都是只在下游圆柱的后面才有漩涡脱落。可是,采用两维有限体积法离散N-S方程计算该流场与实验结果完全不符合,原因尚不清楚。李景银 K Lam K T Chan R M C So 2004工程热物理学报2004,25,1:14
2Inhibition of pacemaker activity in interstitial cells of Cajal by LPS via NF-κB and MAP kinase显示文摘AIM:To investigate lipopolysaccharide(LPS) related signal transduction in interstitial cells of Cajal(ICCs) from mouse small intestine.METHODS:For this study,primary culture of ICCs was prepared from the small intestine of the mouse.LPS was treated to the cells prior to measurement of the membrane currents by using whole-cell patch clamp technique.Immunocytochemistry was used to examine the expression of the proteins in ICCs.RESULTS:LPS suppressed the pacemaker currents of ICCs and this could be blocked by AH6809,a prostaglandin E2-EP2 receptor antagonist or NG-Nitro-Larginine Methyl Ester,an inhibitor of nitric oxide(NO) synthase.Toll-like receptor 4,inducible NO synthase or cyclooxygenase-2 immunoreactivity by specific antibodies was detected on ICCs.Catalase(antioxidant agent) had no action on LPS-induced action in ICCs.LPS actions were blocked by nuclear factor kB(NF-kB) inhibitor,actinomycin D(a gene transcription inhibitor),PD 98059(a p42/44 mitogen-activated protein kinases inhibitor) or SB 203580 [a p38 mitogen-activated protein kinases(MAPK) inhibitor].SB 203580 also blocked the prostaglandin E2-induced action on pacemaker currents in ICCs but not NO.CONCLUSION:LPS inhibit the pacemaker currents in ICCs via prostaglandin E2-and NO-dependent mechanism through toll-like receptor 4 and suggest that MAPK and NF-kB are implicated in these actions.Dong Chuan Zuo Seok Choi Pawan Kumar Shahi Man Yoo Kim Chan Guk Park Young Dae Kim Jun Lee In Yeoup Chang Insuk So Jae Yeoul Jun 2013World Journal of Gastroenterology2013,19,8:9
3A six-year descriptive epidemiological study of human coronavirus infections in hospitalized patients in Hong Kong显示文摘We conducted a six-year epidemiological study on human coronaviruses(HCoVs) circulating in Hong Kong, using 8275 nasopharyngeal samples from patients with acute respiratory tract infections. HCoVs were detected in 77(0.93%) of the samples by a pan-HCoV RT-PCR assay. The most frequently detected HCoV species was HCoV-OC43(0.58%), followed by HCoV-229E(0.15%),HCoV-HKU1(0.13%) and HCoV-NL63(0.07%). HCoVs were detected throughout the study period(September 2008–August 2014), with the highest detection rate from September 2010 to August2011(22/1500, 1.47%). Different seasonal patterns of each HCoV species in Hong Kong were noted.HCoV-OC43 was predominant in the fall and winter, whereas HCoV-HKU1 showed peak activity in winter, with a few cases occurred in spring and summer. HCoV-229 E mainly occurred in winter and spring, while HCoV-NL63 was predominant in summer and autumn. HCoVs most commonly infect the elderly and young children, with median age of 79.5 years(range, 22 days to 95 years).Intriguingly, the detection rate of HCoV-OC43 in the age group of > 80 years(26/2380, 1.09%) was significantly higher than that in the age group of 0–10 years(12/2529, 0.47%)(P < 0.05). These data provides new insight into the epidemiology of coronaviruses.Cyril C.Y.Yip Carol S.F.Lam Hayes K.H.Luk Emily Y.M.Wong Rodney A.Lee Lok-Yee So Kwok-Hung Chan Vincent C.C.Cheng Kwok-Yung Yuen Patrick C.Y.Woo Susanna K.P.Lau 2016Virologica Sinica2016,31,1:9

7Improvement of diabetes and hypertension after gastrectomy: A nationwide cohort study显示文摘AIM: To evaluate the effect of gastrectomy on diabetes mellitus(DM) and hypertension(HTN) in non-obese gastric cancer patients. METHODS: A total of 100000 patients, diagnosed with either type 2 DM or HTN, were randomly selected from the 2004 Korean National Health Insurance System claims. Among them, 360 diabetes and 351 hypertensive patients with gastric cancer who had been regularly treated without chemotherapy from January 2005 to December 2010 were selected. They were divided into three groups according to their treatment methods: total gastrectomy(TG), subtotal gastrectomy(STG) and endoscopic resection(ER). RESULTS: The drug discontinuation rate of antidiabetic and anti-hypertensive agents after gastric cancer treatment was 9.7% and 11.1% respectively. DM appeared to be improved more frequently(22.8%) and earlier(mean ± SE 28.6 ± 1.8 mo) in TG group than in the two other groups [improved in 9.5% of ER group(37.4 ± 1.1 mo) and 6.4% of STG group(47.0 ± 0.8 mo)]. The proportion of patients treated with multiple drugs decreased more notably in TG group compared to others(P = 0.001 in DM, and P = 0.035 in HTN). In TG group, adjusted hazard ratio for theimprovement of DM was 2.87(95%CI: 1.15-7.17) in a multi-variate analysis and better control of DM was observed with survival analysis(P < 0.001).CONCLUSION: TG was found to decrease the need for anti-diabetic medications which can be reflective of improved glycemic control, to a greater extent than either ER or STG in non-obese diabetic patients.Eun Kyung Lee So Young Kim You Jin Lee Mi Hyang Kwak Hak Jin Kim Il Ju Choi Soo-Jeong Cho Young Woo Kim Jong Yeul Lee Chan Gyoo Kim Hong Man Yoon Bang Wool Eom Sun-Young Kong Min Kyong Yoo Jong Hyock Park Keun Won Ryu 2015World Journal of Gastroenterology2015,21,4:3
8Mitochondrial neuronal uncoupling proteins:a target for potential disease-modification in Parkinson’s disease Philip显示文摘This review gives a brief insight into the role of mitochondrial dysfunction and oxidative stress in the converging pathogenic processes involved in Parkinson’s disease(PD).Mitochondria provide cellular energy in the form of ATP via oxidative phosphorylation,but as an integral part of this process,superoxides and other reactive oxygen species are also produced.Excessive free radical production contributes to oxidative stress.Cells have evolved to handle such stress via various endogenous anti-oxidant proteins.One such family of proteins is the mitochondrial uncoupling proteins(UCPs),which are anion carriers located in the mitochondrial inner membrane.There are five known homologues(UCP1 to 5),of which UCP4 and 5 are predominantly expressed in neural cells.In a series of previous publications,we have shown how these neuronal UCPs respond to 1-methyl-4-phenylpyridinium(MPP+;toxic metabolite of MPTP)and dopamine-induced toxicity to alleviate neuronal cell death by preserving ATP levels and mitochondrial membrane potential,and reducing oxidative stress.We also showed how their expression can be influenced by nuclear factor kappa-B(NF-B)signaling pathway specifically in UCP4.Furthermore,we previously reported an interesting link between PD and metabolic processes through the protective effects of leptin(hormone produced by adipocytes)acting via UCP2 against MPP+-induced toxicity.There is increasing evidence that these endogenous neuronal UCPs can play a vital role to protect neurons against various pathogenic stresses including those associated with PD.Their expression,which can be induced,may well be a potential therapeutic target for various drugs to alleviate the harmful effects of pathogenic processes in PD and hence modify the progression of this disease.WL Ho Jessica WM Ho Hui-Fang Liu Danny HF So Zero HM Tse Koon-Ho Chan David B Ramsden Shu-Leong Ho 2012Translational Neurodegeneration2012,1,1:3
