1Diagnostic accuracy of endoscopic ultrasound in pancreatic neuroendocrine tumors: A systematic review and meta analysis显示文摘AIM: To detect pancreatic neuroendocrine tumors (PNETs) has been varied. This study is undertaken to evaluate the accuracy of endoscopic ultrasound (EUS) in detecting PNETs.METHODS: Only EUS studies confirmed by surgery or appropriate follow-up were selected. Articles were searched in Medline, Ovid journals, Medline nonindexed citations, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Pooling was conducted by both fixed and random effects model). RESULTS: Initial search identified 2610 reference articles, of these 140 relevant articles were selected and reviewed. Data was extracted from 13 studies (n = 456) which met the inclusion criteria. Pooled sensitivity of EUS in detecting a PNETs was 87.2% (95%CI: 82.2-91.2). EUS had a pooled specificity of 98.0% (95%CI: 94.3-99.6). The positive likelihood ratio of EUS was 11.1 (95%CI: 5.34-22.8) and negative likelihood ratio was 0.17 (95%CI: 0.13-0.24). The diagnostic odds ratio, the odds of having anatomic PNETs in positive as compared to negative EUS studies was 94.7 (95%CI: 37.9-236.1). Begg-Mazumdar bias indicator for publication bias gave a Kendall's tau value of 0.31 (P = 0.16), indication no publication bias. The P for χ2 heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity to detect PNETs. EUS should be strongly considered for evaluation of PNETs.Srinivas R Puli Nikhil Kalva Matthew L Bechtold Smitha R Pamulaparthy Micheal D Cashman Norman C Estes Richard H Pearl Fritz-Henry Volmar Sonu Dillon Michael F Shekleton David Forcione 2013World Journal of Gastroenterology2013,19,23:14
2Cyclooxygenase-2 plays a central role in the genesis of pancreatitis and associated lung injury显示文摘BACKGROUND: The exact mechanism by which cyclooxy- genase-2 (COX-2) promotes inflammation in pancreatitis in obscure. This study was undertaken to investigate the role of COX-2 inhibition in an animal model of pancreati- tis , a disease process characterized by a systemic inflamma- tory response and ensuing neutrophil-mediated lung injury. METHODS: Pancreatitis was induced in 24 Sprague-Daw- ley rats by intraperitoneal injection of 20% L-arginine (500 mg/100 g body weight). The animals were randomized into 3 groups (8 rats in each group); controls and rats with pancreatitis intravenously resuscitated with either normal saline (0.9% NaCl 3 ml/kg) at 24 and 48 hours or COX-2 inhibitor (parecoxib 1 mg/kg). Pancreatic and lung inju- ries were assessed histologically. Lung injury was assessed utilizing wet;dry ratio and myeloperoxidase activity to in- dicate pulmonary neutrophil infiltration. A Western blot was used to determine COX-2 protein expression in pancrea- tic tissue. RESULTS: The animals treated with COX-2 inhibitors dis- played significantly less pancreatic and lung injuries than their normal saline counterparts. Histological pancreatic and lung injury scores were significantly reduced (P <0.05) in the COX-2 treated group. Lung wet: dry ratios were sig- nificantly improved and pulmonary neutrophil infiltration was attenuated in the COX-2 group (P<0.05). Western blot analysis confirmed attenuated COX-2 protein expression. CONCLUSION: This study shows, for the first time in a rat model, that adjuvant COX-2 inhibition significandy attenu- ates the severity of both pancreatitis and its associated sys- temic inflammatory response and end-organ injury.Gavin O'Brien Conor J Shields Desmond C Winter John P Dillon 2005Hepatobiliary & Pancreatic Diseases International2005,4,1:12

6白蚁肠道二株链霉菌株所产纤维素酶的分离、纯化及其特性(英文)显示文摘通过硫酸铵沉析、依次过葡聚糖G100和阴离子交换树脂DEAE葡聚糖A50柱,从白蚁(Odontotermesformosanus)肠道2株放线菌株发酵液中获得了1种葡聚糖外切酶(C1)、2种葡聚糖内切酶(CX)和1种β-葡萄糖苷酶(β-glucosidase,βG)。该2株放线菌株在形态、生长、生理生化特性上显示属于链霉菌属种类。SDS-PAGA电泳分析表明上述4种酶的分子质量分别为76.9、22.3、66.2、31.9kD。外切酶在pH 5.6,内切酶和β-葡萄糖苷酶在pH 5.0;以及内切酶和外切酶在50℃,β-葡萄糖苷酶在40℃时,有最大酶活性,甚至温度高达70℃时,这些酶仍有50%以上的酶活性。二价阳离子如Fe2+、Ca2+在质量浓度100mg/L条件下对酶有激活作用,而Mn2+、Cu2+、Zn2+、Co2+对酶活起抑制作用。结果表明来自白蚁肠道2株链霉菌株所产的纤维素酶可能以Fe2+和Ca2+作为辅基,属于酸性、耐热性酶。这类酶具备用于工业上分解不溶性的纤维素的能力。霍光华 黄小晖 Shannon DILLON 何刚强 陈明辉 龙昊知 2012食品科学2012,33,17:4

9Proteomic and genomic studies of non-alcoholic fatty liver disease-clues in the pathogenesis显示文摘Non-alcoholic fatty liver disease(NAFLD)is a widely prevalent hepatic disorder that covers wide spectrum of liver pathology.NAFLD is strongly associated with liver inflammation,metabolic hyperlipidaemia and insulin resistance.Frequently,NAFLD has been considered as the hepatic manifestation of metabolic syndrome.The pathophysiology of NAFLD has not been fully elucidated.Some patients can remain in the stage of simple steatosis,which generally is a benign condition;whereas others can develop liver inflammation and progress into non-alcoholic steatohepatitis,fibrosis,cirrhosis and hepatocellular carcinoma.The mechanism behind the progression is still not fully understood.Much ongoing proteomic researches have focused on discovering the unbiased circulating biochemical markers to allow early detection and treatment of NAFLD.Comprehensive genomic studies have also begun to provide new insights into the gene polymorphism to understand patientdisease variations.Therefore,NAFLD is considered a complex and mutifactorial disease phenotype resulting from environmental exposures acting on a susceptible polygenic background.This paper reviewed the current status of proteomic and genomic studies that have contributed to the understanding of NAFLD pathogenesis.For proteomics section,this review highlighted functional proteins that involved in:(1)transportation;(2)metabolic pathway;(3)acute phase reaction;(4)antiinflammatory;(5)extracellular matrix;and(6)immune system.In the genomic studies,this review will discuss genes which involved in:(1)lipolysis;(2)adipokines;and(3)cytokines production.Jun Wei Lim John Dillon Michael Miller 2014World Journal of Gastroenterology2014,20,26:3

13温度测量系统对ADC的要求显示文摘引言 适用于温度测量的温度传感器有好几种。为具体应用选择适当的温度传感器取决于待测温度范围以及所需要的精度。系统精度取决于温度传感器的精度以及用于将传感器输出数字化的模数转换器(ADC)的性能。多数情况下,传感器的信号幅度相当小,需要一种高分辨率的ADC。∑-△ADC分辨率高,通常包含温度测量系统所需的内置电路,如激励电流源。本文讨论不同类型的温度传感器(热电偶、电阻式温度检测器(RTD)、热敏电阻以及热敏二极管)以及连接传感器和ADC所需要的电路,还介绍对ADC的性能要求。Mary Mc Carthy Eamonn Dillon 2006世界电子元器件2006,,8:2
