微孔杂交检测登革病毒及其分型方法的建立
2007/7/25
聚合酶联反应(PCR)技术自20世纪80年代出现以来，已被广泛应用于疾病的核酸诊断，其扩增产物的检测主要依赖于琼脂糖或聚丙烯酰氨凝胶电泳，由于临床标本复杂，常出现非特异性扩增条带或电泳拖尾现象[1][2]，给结果的判定带来困难，采用PCR方法往往难以作出确诊。为了探讨更加敏感、特异的登革病毒快速检测及分型方法，我们在分析登革病毒1～4型病毒基因组序列的基础上，分别设计针对登革病毒病毒1～4型的特异...
登革2型病毒NGC株基因组亚克隆的构建及其鉴定

登革病毒(DV)属黄病毒科黄病毒属，基因组为单股正链RNA，全长约11 kb，编码3种结构蛋白(C, PrM和E)和7种非结构蛋白(NS1,NS2a, NS2b, NS3, NS4a, NS4b和NS5)。共有4种血清型，均可引起登革热(DF)、登革出血热(dengue hemorrhagic fever, DHF)和登革休克综合征(dengue shock syndrome, DSS)[1][2...
广东流行的三株登革1型病毒包膜蛋白基因的序列测定与分析
2007/7/25
登革热(dengue fever，DF)是一种由蚊媒传播，登革病毒感染引起的急性传染病，广泛流行于全球热带及亚热带地区的60多个国家和地区，其中与我国接壤的东南亚国家最为严重，每年全球发病人数高达数千万，已构成世界性公共卫生问题[1]。国内自1978年登革热在佛山首次爆发以来，先后在海南、广西、福建等地发生过十多次大的流行，给疫区居民及驻训部队带来严重威胁。登革病毒(DV)属黄病毒科成员，有4个血...
空心莲子草抗登革病毒作用的实验研究
2007/7/25
空心莲子草(Alternanthera Philoxeroides Griseb)又名水花生、螃蜞菊、系苋科莲子草属植物，具清热、凉血、利尿、解毒的作用。临床上用于感染性疾病的治疗[1]。本研究利用体外细胞培养对空心莲子草抗登革病毒(Dengue virus, DV)的效果进行观察研究，以确证空心莲草抗DV的作用，为该药用于DV的防治提供实验依据。
登革病毒cDNA的生物信息学分析及其Oligo探针设计
2007/7/25
生物芯片是近年来在生命科学领域中崭露头角的一项新技术，凭其快速、高效、敏感、经济、平行化、自动化等特点，在序列分析、基因表达、基因组研究及基因诊断等领域已显示出很好的应用前景[1][2][3][4]。生物芯片的特点决定它必须依赖于生物信息学的手段和方法来进行芯片设计中探针的筛选、芯片分析结果的研究等[5][6]。本研究根据GenBank数据库中的生物信息，利用美国国家生物技术信息中心(NCBI)中...
