An assessment of potential interventions to reduce the totoaba illegal trade market
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract The illegal trade in totoaba (Totoaba macdonaldi) is causing adverse social, ecological, and economic impacts. This illegal activity is accelerating the overexploitation of totoaba and pushing the critically endangered vaquita (Phocoena sinus) closer to extinction.

Effect of Ba Zhu Decoction(BZD) on the related mechanisms of Aβ formation in 5xFAD transgenic mice [PDF]
, 2016 目的：巴茱合剂是本人硕士导师治疗阿尔兹海默病(AD)的经验方，前期临床研究证明，巴茱合剂能有效缓解AD患者认知功能障碍，但对巴茱合剂的作用机制尚未深入研究。本文旨在通过AD转基因动物再次验证巴茱合剂的治疗效果，并进一步探索巴茱合剂治疗AD的相关分子生物学机制。 方法：（1）选取新型APP/PS1转基因小鼠(5xFAD小鼠)作为实验对象。将3月龄5xFAD小鼠随机分为模型组(5xFAD-Control)、巴茱合剂低剂量组(5xFAD-BZD-L)、中剂量组(5xFAD-BZD-M)、高剂量组(5xFAD ...

Wildlife Letters, Volume 2, Issue 3, Page 131-139, September 2024.Southern flying squirrels (flying squirrel; Glaucomys volans) frequently displace endangered red‐cockaded woodpeckers (RCW; Dryobates borealis) within forest partitions managed specifically for RCW cavities (“cluster partitions”). We found little to no evidence of differences in home range size and composition between flying squirrels within or outside

Toxic Effects and Mechanisms of Polychlorinated Biphenyls(Aroclor 1254) on Glucose Homeostasis in Male Mice [PDF]
, 2015 多氯联苯(PolychlorinatedBiphenyls,PCBs)作为最难以降解的持久性有机污染物之一，其引起的环境问题已经受到了极大的关注。有关环境污染物导致糖尿病的机制已经开展了较多的研究，但是关于环境水平的PCBs长期暴露能否导致糖尿病的发生以及其毒性效应机制还不清楚。本研究以C57BL/6品系青春期雄性小鼠为研究对象，研究环境水平的PCBs长期暴露导致糖尿病发生发展的毒性效应机制。采用浓度分别为0.5、5、50和500μg/kg的Aroclor1254，通过灌胃法对小鼠进行染毒 ...

Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Eradicating invasive predators from islands can result in substantial recovery of seabirds, but the mechanisms that drive population changes remain poorly understood. Meta‐analyses have recently revealed that immigration is surprisingly important to the recovery of philopatric seabirds, but it is not known whether dispersal and philopatry ...
