IRF5 rs10954213基因多态性与系统性红斑狼疮的相关性研究
Zhongguo shiyan zhenduanxue, 2009 目的研究山东地区汉族人群干扰素调节因子5（IRF5）基因rs10954213单核苷酸多态性,探讨其与系统性红斑狼疮易感性之间的关系。方法采用聚合酶链反应和限制性片段长度多态性等方法对92例系统性红斑狼疮患者和88名健康对照IRF5基因rs10954213G/A多态性进行分析,计算基因型和等位基因频率。结果SLE患者IRF5rs10954213GG、GA、AA基因型频率分别是0.318、0.409和0.273,与对照组间有显著差异（χ2=6.36 ...

Effects of ApoE Isoforms Expression on Brain ApoE Lipidation and Amyloid-β Accumulation [PDF]
, 2015 在编码人三种不同apoE蛋白亚型（E2、E3和E4）的APOE等位基因（ε2、ε3和ε4）中，APOEε4等位基因是阿尔茨海默病（Alzheimer’sdisease，AD）最重要的遗传风险因子，APOEε2等位基因则具有保护作用。鉴于apoE蛋白亚型对基于调节apoE蛋白表达的AD治疗可能会有不同的影响，我们通过在人APOE基因定位替换（Targetedreplacement，TR）小鼠脑中过表达不同的人apoE亚型，研究脑中表达不同apoE亚型对apoE脂化和β-淀粉样蛋白（Amyloid-β，Aβ）

Informing spatial conservation prioritization with species’ traits
Conservation Biology, EarlyView.Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Study on the diagnostic value of macrophage migration inhibitory factor in neurosyphilis [PDF]
, 2016 目的： 神经梅毒诊断依赖于实验室检查结果，脑脊液（cerebrospinalfluidrapid，CSF）快速血浆反应素环状卡片试验（rapidplasmareagintest，RPR）常作为神经梅毒的确诊指标，但脑脊液RPR的灵敏度低，易造成漏诊；即使结合脑脊液的其他参数（蛋白和白细胞等），也可能造成神经梅毒的漏诊。巨噬细胞移动抑制因子（macrophagemigrationinhibitoryfactor，MIF）作为一种炎症因子已广泛应用于神经系统疾病的诊断 ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
