2利用抗高血压药相关的遗传变异发现其潜在的功效和副作用显示文摘通过研究药物靶蛋白基因的自然变异可以了解药物的功效。本研究旨在利用这种方法探索抗高血压药的潜在副作用和再利用潜力。研究者首先确定了血管紧张素转换酶抑制剂(angiotensin converting enzyme inhibitor,ACEI)、β受体阻滞剂和钙拮抗剂的合适代表基因。刘青(译) 叶鹏(校) Gill D Georgakis MK Koskeridis F Jiang L Feng Q Wei WQ Theodoratou E Elliott P Denny JC Malik R Evangelou E Dehghan A Dichgans M Tzoulaki I 2019中华高血压杂志2019,0,9:3
3CDX2 protein expression compared to alcian blue staining in the evaluation of esophageal intestinal metaplasia显示文摘AIM:To compare the sensitivity and specificity of CDX2 and alcian blue(AB) p H 2.5 staining in identifying esophageal intestinal metaplasia.METHODS:One hundred and ninty-nine biopsies from 186 patients were retrospectively reviewed and categorized as Barrett's esophagus(BE)(n =108); non-Barrett's esophagus(NBE)(n =48); columnar blue cells(CB) and esophageal glands(EG)(n =43).The biopsies were stained with AB and immunostained for CDX2 using a mouse monoclonal antibody from Biogenex(clone CDX2-88) and the Ventana Discovery X automated immunostainer.The positive and negative predictive value of each group was used to determine the predictive power of CDX2 and AB in diagnosing intestinal metaplasia.RESULTS:All of the 108 BE biopsies(100%) were positive for AB and 102 of them(94.4%) were positive for CDX2.The six BE patients(5.6%) who failed to stain with CDX2 were found to have lost the focus of intestinal metaplasia upon deeper sectioning for immunostaining.Both AB and CDX2 were negative in 43 out of 48(89.6%) NBE cases.Five NBE patients(10.4%) were falsely positive for AB due to the presence of EG and CB in these biopsies.These cases were all CDX2 negative.In addition,5 AB negative NBE were found to be CDX2 positive.Based on these results the CDX2 immunostain had similar sensitivity but higher specificity(100% vs about 91%) than AB in detecting intestinal type metaplasia in these samples.Our data shows that CDX2 has a better PPV in detecting intestinal metaplasia as compared to AB(95.6% vs 71.5%,respectively).CONCLUSION:CDX2 has a better positive predictive value than AB in detecting intestinal metaplasia.CDX2may be useful when challenged by gastro-esophageal biopsies containing mimikers of BE.Dennis R Johnson Maisoun Abdelbaqui Maryam Tahmasbi Zoltan Mayer Hung-Wei Lee Mokenge P Malafa Domenico Coppola 2015World Journal of Gastroenterology2015,21,9:2
4大豆油和棕榈油制备生物润滑油基础油三羟甲基丙烷脂肪酸酯的理化性质分析显示文摘按照美国材料与试验协会国际标准(ASTM)对大豆油和棕榈油制备的生物润滑油基础油三羟甲基丙烷脂肪酸酯(TMPFAE)的理化性质进行测定。大豆油脂肪酸甲酯(FAME)与三羟甲基丙烷(TMP)分别按照物质的量比为4∶1、3.1∶1,棕榈油FAME与TMP按照物质的量比3.1∶1进行反应,用K2CO3作为催化剂合成三羟甲基丙烷脂肪酸三酯(TFATE)。结果表明:棕榈油FAME转化率为76.95%,TMPFAE中TFATE含量为66.88%,大豆油FAME(nFAME∶nTMP=3.1∶1)转化率为74.83%,TMPFAE中TFATE含量为54.76%;大豆油TMPFAE低温性能较好,但是氧化稳定性较差,运动黏度和动力黏度较低;而棕榈油TMPFAE氧化稳定性好,但是低温性能差。孙果 MONONO Ewumbua WIESENBORN Dennis P 汪勇 2016中国油脂2016,41,6:2
