汉族人群Y染色体多拷贝基因座DYS464遗传多态性

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2006
【目的】 研究Y染色体多拷贝基因座DYS464遗传多态性在汉族群体中的分布规律。【方法】 选择106例汉族无亲缘关系男性个体作为研究对象,荧光标记引物PCR扩增DYS464基因座片段,ABl377自动测序仪上变性聚丙烯酰胺凝胶电泳分析PCR产物,并对不同重复序列分别测序。【结果】 DYS464基因座在106例汉族男性无关个体中发现有8种片段。变异11~18次。根据其中任意4种片段的组合,即片段大小和峰高的比率来命名等位基因,E-型命名方法,观察到61种等位基因,其中36种等位基因只出现1次 ...

ApoE基因多态性与动脉粥样硬化性脑梗死的相关性研究 [PDF]

open access: yes, 2018
目的分析ApoE基因与血脂和颈动脉粥样硬化程度的关系,进一步探讨ApoE基因与动脉粥样硬化性脑梗死的相关性。方法采用病例-对照研究的方法,收集厦门大学附属第一医院神经内科的95例缺血性脑卒中和65例非缺血性脑卒中住院患者。检测患者的ApoE基因型、血脂及颈动脉粥样硬化程度。结果与E2/E3比较,基因型E3/E3、E3/E4可能是缺血性脑卒中的保护因素;缺血性和非缺血性脑卒中患者在血浆TC、LDL-C、ApoB含量比较上均为E3/E4> E3/E3>E2/E3,且2组血浆LDL-C浓度在E3/E4与E2 ...

Coalition Opportunity Structures and Advocacy Coordination in Consensus and Majoritarian Democracies

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Research on advocacy coalitions suggests that belief homophily—the tendency of actors to coordinate based on shared policy beliefs—drives coalition formation. However, coalition opportunity structures, which are shaped by institutional contexts, may influence the extent to which belief homophily matters.

Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

基于多色探针熔解曲线分析技术的华法林个体化用药相关基因多态性快速检测方法 [PDF]

open access: yes, 2019
华法林是一种广泛使用的抗凝剂,其治疗窗口较窄,患者间达到抗凝所需剂量的变异性大。已有研究表明CYP2C9*3 (rs1057910)、CYP2C9 IVS3-65G>C (rs9332127)、VKORC1 c.-1639G>A (rs9923231)和CYP4F2*3 (rs2108622)的单核苷酸多态性(SNP)是影响中国人群华法林敏感性的主要遗传因素。该研究利用多色探针熔解曲线(MMCA)技术,建立可同时检测4个华法林敏感性基因多态性的单管PCR反应体系,可在2.5 h内完成检测,能检测低至50
