Association of the polymorphis ms in STIM1 / ORAI1 / TRPC1 genes with the risk of calcium u rolithiasis [PDF]
, 2015 目的：寻找基质相互作用因子1（Stromalinteractionmolecule1，STIM1）、钙释放激活钙通道调节分子1（Calciumrelease-activatedcalciummodulator1，ORAI1）和瞬时受体电位阳离子通道1（Transientreceptorpotentialcationchannel1，TRPC1）基因中与泌尿系含钙结石发病有关的易感位点及可能存在的单体型，探讨这三者基因多态性与泌尿系含钙结石发病的关联性。 方法：1、采用病例-对照研究策略 ...

Robust metrics for quantifying and comparing resistance and recovery in experimental studies
Methods in Ecology and Evolution, EarlyView.Abstract Various indices have been developed to experimentally quantify resistance and recovery (two components of engineering resilience) in response to anthropogenic and natural disturbances. This diversity complicates the selection of appropriate metrics for comparing resilience across ecosystems and studies.

Gene structure analysis and differentially splicing between Plasmodium yoelii subspecies [PDF]
, 2016 啮齿类动物约氏疟原虫（Plasmodiumyoelii）是研究宿主-寄生虫相互关系和疟原虫病理分子基础的一种重要的动物模型。尽管约氏疟原虫YM虫株的基本基因组信息已被测定，在最近也有许多啮齿类动物疟原虫的RNA-seq序列信息已见报道，但不同疟原虫品系或者亚种之间可能存在基因编码区及mRNA转录结构上的差异。构建多种疟原虫品系和亚种的cDNA文库将有助于我们对疟原虫遗传模式和转录组结构的认识。 本研究，我们用约氏疟原虫NSM虫株有或无MQ药物压力的红内期原虫样本构建了两个cDNA文库并对其进行深度测序 ...

Conservation Biology, EarlyView.Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...

Studies on Heat Tolerance in Abalone Based on the Measurement of Heart Rate [PDF]
, 2016 鲍是海产八珍之首，2015年，我国的鲍产量已经超过13万吨，其中福建省的产量占全国的80%。皱纹盘鲍为温带种，原分布于我国黄、勃海海域，1990年代后期南移福建后，获得了极大发展，由此福建逐步成为我国鲍养殖的主产区。但福建海域的夏季高水温往往导致鲍的高死亡率，这一直困扰着鲍养殖产业的发展。因此，培育耐高温的养殖新品种显得格外重要，而其中建立鲍的耐高温性状的准确测评方法是品种培育的关键。本研究中，我们通过测定阿氏拐点温度（Arrheniusbreakpointtemperature，ABT ...

Underrepresentation of bats in Africa's protected areas
Conservation Biology, EarlyView.Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

Association of MTHFR C677T polymorphism with male infertile in Xiamen area [PDF]
, 2017 目的探讨亚甲基四氢叶酸还原酶（MTHFR）C677T基因多态性与男性不育的相关性。方法选取少、弱精症患者66例和无精症患者74例为实验组,精液正常且有正常孕育史的男性96例为对照组,分析MTHFR C677T基因多态性在三组中分布的差异。结果与对照组相比,少、弱精组中MTHFR C677T各基因型的频率差异没有显著性意义（P〉0.05）;与对照组相比,无精组中MTHFR C677T各基因型的频率差异没有显著性意义（P〉0.05）。结论在少、弱精症患者、无精症患者和健康人中,基因多态性分布无显著差异 ...
