Effect of Neu5Ac supplementation on learning and memory in weanling rats and rat pups [PDF]
, 2016 研究背景：新生儿生长发育对营养物质有特殊的要求，任何营养素的匮乏对机体的正常生长和器官结构功能的发育都有深远影响，对脑发育的影响尤为重要。早期营养对大脑的结构和功能有着不可逆转的影响，一旦错过大脑发育的关键期，产生的缺陷后天将无法弥补。新生儿期营养素的缺乏会影响其认知功能。 N-乙酰神经氨酸（N-acetylneuraminicacids，Neu5Ac）是人体中最常见的唾液酸。Neu5Ac在人体中普遍存在，在脑组织及母乳中含量较高；唾液酸作用于神经元细胞膜及突触，在神经系统中产生重要作用 ...

Conservation Biology, EarlyView.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

The role of MiR-23b-3p in the epileptogenesis [PDF]
, 2016 癫痫是指脑部持续存在能导致癫痫反复发作，并出现相应的神经生物学、认知、心理学，以及社会学等方面的后果的脑部疾患。目前miRNA在癫痫发生发展中的作用引起越来越多的重视。miR-23b-3p是具有多种生物学作用的miRNA，如调节神经元增殖、分化和凋亡等,参与多种神经退行性疾病的病理机制。 本研究通过腹腔注射海人酸（Kainicacid,KA）构建小鼠癫痫模型，发作达到Racine标准的4-5级作为实验组纳入标准，对照组注射相同剂量的生理盐水，并应用荧光定量PCR法对皮层和海马组织中miR-23b-3p ...

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, EarlyView.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...
