Sci Transl Med:野外便携式ELISA系统

2018-05-02 药明康德 学术经纬

血清学调查(serosurveys)能够帮助确定广大人口中出现传染病爆发的风险,从而帮助制定疫苗接种策略。但是在偏远地区,由于无法及时将样本有效地保存并且运送到实验室进行检测,血清学调查很难进行。

血清学调查(serosurveys)能够帮助确定广大人口中出现传染病爆发的风险,从而帮助制定疫苗接种策略。但是在偏远地区,由于无法及时将样本有效地保存并且运送到实验室进行检测,血清学调查很难进行。使用测流检测(lateral flow)或微流控(microfluidics)系统可以让研究人员进行实地检测,但是通常这些方法无法同时检测多个样本。加拿大多伦多大学(University of Toronto)的研究人员开发出一种便携式微流控免疫检测系统。它利用喷墨打印的数字微流控装置(inkjet-printed digital microfluidic cartridges)能够在野外进行血清免疫检测。在肯尼亚(Kenya)西北部的Kakuma难民营的实地检验表明这一系统能够检测出年龄为9-59月的儿童体内麻疹(measles)和风疹(rubella)免疫球蛋白的存在。虽然它的灵敏度和特异性比不上在中心实验室(centralized laboratory)进行的ELISA检测,但是这一系统在偏远地区可以帮助进行全球性的血清学监测,为改善全球健康提供一个新工具。

Aust Dent J.:慢性和侵袭性牙周炎患者龈沟液中MDA、SOD以及褪黑素的水平

背景:本研究的目的是为了探讨慢性牙周炎(CP)和广泛性侵袭性牙周炎(GAgP)患者龈沟液(GCF)中作为氧化应激生物学标志物的氧化物歧化酶(MDA)、丙二醛(SOD)以及褪黑素的水平。方法:研究纳入了65名患者,15名健康对照者,25名CP患者,25名GAgP患者。测量所有研究对象的菌斑指数(PLI)、牙龈指数(GI)、牙周袋深度(PD)以及临床附着水平(CAL),并收集所有研究对象的GCF。采用
