中国成都汉族群体三个Y-STR基因座复合扩增及其单倍型的研究

目的建立一种同步检测Y-STR基因座的方法。方法采用复合扩增的方法同时对三个基因座(DYS390、DYS391及DYS393)进行扩增。结果成功地对这三个Y-STR基因座进行了同步扩增,并用其对中国成都汉族群体进行群体遗传学研究。结论三个Y-STR基因座在中国成都汉族群体个人识别几率为0.8965±0.0081,证明这个体系可用于个人识别和群体遗传学研究。     

Argentine Nacionalismo before Perón: The Case of the Alianza de la Juventud Nacionalista, 1937–c. 1943

As the 1930s moved towards their close, a new generation of young men began to dominate the political wing of a generally more radical and assertive Argentine Nacionalismo, replacing the old guard that had found its inspiration in General José F. Uriburu and the regime he had led between September 1930 and February 1932. The Alianza de la Juventud Nacionalista, set up in September 1937, was the most important nacionalista faction of the period. It shared with other nacionalista factions the rejection of liberalism, parliamentary democracy and communism, but in contrast to the elitist and anti-popular orientation of earlier organisations, it aggressively tried to enlist popular support by portraying itself as a group genuinely concerned about the needs of the masses. The Alianza also distanced itself from the glorification of nineteenth-century Argentina, another hallmark of previous groups. Although it failed in its efforts to build up a significant following, the analysis nevertheless demonstrates that the organisation can be described as a genuinely fascist movement.

2个Y——STR基因座在成都汉族群体中的遗传学研究

目的为了寻求新的适合于法医学应用的Y染色体STR基因座,我们调查了基因座DYS442和DYS446在成都群体中的分布. 方法样本来自于成都地区汉族无血缘关系的个体,通过Chelex法提取样本DNA,利用PCR扩增硝酸银染色方法进行分型 . 结果 DYS442是一个四核苷酸简单重复基因座,而DYS446则为五核苷酸简单重复基因座.男性样本都出现了谱带,而女性样本则无PCR产物.DYS442基因座和DYS44 6基因座变异度分别为:0.6867、0.7552. 结论 DYS442和DYS446是非常适合于法医学应用的STR基因座.     

荧光复合扩增检测3个Y—STR基因座单倍型

目的建立检测3个Y-STR基因座Y-GATA-A7.1、DYS456和DYS443的荧光复合扩增体系,并获取中国汉族人群单倍型频率分布。方法用荧光标记引物对郑州地区203名汉族男性无关个体进行3个基因座复合扩增,ABI3100型遗传分析仪检测、分型。结果Y-GATA-A7.1、DYS456和DYS443基因座分别检出5、6和6个等位基因,其基因多样性(GD值)分别为0.6692、0.5839和0.7053。三个基因座构成的单倍型共有44种,单倍型多样性(HD值)为0.9523。结论建立的3个Y-STR基因座荧光标记复合扩增系统具有很高的识别能力,可应用于法医学实践。

Optimization of Human mtDNA Control Region Sequencing for Forensic Applications

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye^® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye^® XTerminator^? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.
