We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Background – Recurrent urticaria is common in horses. The pathophysiology is poorly understood and treatment options are limited. Often only glucocorticoids are effective for controlling clinical signs, albeit with potential adverse effects. Studies investigating new treatments need a validated objective scoring system for the grading of skin lesions ...

Generating amphioxus Hedgehog knockout mutants and phenotype analysis [PDF]
文昌鱼隶属脊索动物门头索动物亚门,是无脊椎动物到脊椎动物的过渡类群,其躯体结构简单,是研究胚胎发育的理想材料。本文以文昌鱼为实验对象,利用TAlEn敲除技术对HEdgEHOg(HH)基因在胚胎发育中的功能进行了研究。在文昌鱼HH基因翻译起始位点下游附近选取TAlEn目标位点,根据此序列组装相应TAlEn重组质粒,体外合成M rnA,向未受精卵注射M rnA后,经体外受精获得f0代胚胎。效率分析显示,靶向该基因的TAlEn M rnA可导致f0代代胚胎在相应基因组区域发生突变的比例为34 ...

Abstract Free‐ranging cats pose significant threats to biodiversity, yet the cat‐related media online has attracted millions of viewers. The reasons behind this surge in popularity, however, remain underexplored. To address this gap, we conducted a comparative culturomic analysis of over 6 million comments and 60,000 unique tags from over 3 million ...

野生动物饲养管理认证是中国森林认证的新领域,其发展尚处于初级阶段。虽现已有多家单位通过认证,但尚没有开展野生动物饲养管理认证绩效跟踪的相关研究,对于认证效果了解甚少。基于此,本文开展野生动物饲养管理认证跟踪调研及实践研究,以期为主管部门、科研单位及认证机构开展相关工作提供参考依据和重要借鉴。研究表明,野生动物饲养管理认证能够有效解决各单位在野生动物饲养管理过程中面临的问题,饲养管理体系得到有效提升和改善。因此建议主管部门加强对野生动物饲养管理认证的采信,加强宣传推广、技术支持及能力建设等。
