Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Protected areas (PAs) are pivotal to biodiversity conservation, yet their efficacy is compromised by insufficient funding and management. So‐called other effective area‐based conservation measures (OECMs) present a paradigm shift and address PA limitations.

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Multifunctional landscapes that support economic activities and conservation of biological diversity (e.g., cattle ranches with native forest) are becoming increasingly important because small remnants of native forest may comprise the only habitat left for some wildlife species. Understanding the co‐occurrence between wildlife and disturbance

Zhongguo shiyan zhenduanxue, 2008 目的探讨肝素抗凝剂对化学发光法测定HCG的影响,以验证是否可用肝素抗凝血进行检测来缩短检测时间。方法用肝素抗凝和普通真空采血管抽取20份患者标本进行对比测定,同时用高于抗凝管10倍浓度的肝素抗凝剂对20份样本中的高中低浓度的HCG样本进行干扰试验。结果肝素抗凝和普通真空采血管两组数据经配对资料t检验（P>0.05）,差异无显著性;高浓度肝素抗凝剂对高、中、低浓度的HCG干扰值均小于干扰试验对照组1.96s,最大干扰百分比不足0.9%。结论肝素抗凝剂对化学发光法测定HCG无影响,可用肝素抗凝血样进行检测。

The preliminary study on the dyslipidemia in rats with autoimmune myocarditis [PDF]
, 2016 目的：心肌炎是心肌间质中局限或弥漫性的急性或慢性炎症，目前关于心肌炎中血脂代谢的相关研究较少，本课题通过建立大鼠实验性自身免疫性心肌炎模型（EAM模型），初步探讨心肌炎中血脂代谢紊乱可能的分子调节机制。 方法：利用猪心肌肌球蛋白和完全弗氏佐剂充分混合后，于第0天皮下注射建立大鼠EAM模型，留取心脏标本行组织切片H&E染色、心脏体重比、RealtimePCR、Westernblot评估心肌组织炎症程度；GPO-PAP法血脂试剂盒检测血脂水平；Filipin染色检测心肌组织内胆固醇水平 ...

Experimentally testing animal responses to prescribed fire size and severity
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Infant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 3, Page 341-353, May 2024.Abstract Contradictory results in the extant literature suggests that additional risk factors should be considered when exploring the impacts of maternal smartphone use on mother‐infant relationships. This study used cluster analysis to explore whether certain risk factors were implicated in mother‐infant dyads with high smartphone use and low mother ...

Zhongguo shiyan zhenduanxue, 2006 目的研究己糖激酶法和葡萄糖氧化酶法测定血液血糖含量时的干扰因素及其影响程度。方法应用己糖激酶法和葡萄糖氧化酶法试剂盒对临床标本进行血糖的测定,观察其时间反应曲线,同时测定其它24项常用生化示,分析对血糖测定产生干扰的物质及其影响程度。结果通过对临床标本的测定,我们发现体内的代谢产物对己糖激酶法血糖测定产生两种干扰,一种是在胆红素增高时伴随的快速干扰,一种是在革些病理情况下产生的慢反应干扰。结论血糖测定是临床最常用的检测指标,准确测定血糖浓度对指导临床治疗非常重要,所以研究血糖测定的干扰因素是非常有意义的。
