Effect of Neu5Ac supplementation on learning and memory in weanling rats and rat pups [PDF]

open access: yes, 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 ...

A tale of two disasters: Unpacking how social learning from the Ebola epidemic shaped COVID‐19 response in informal settlements in Freetown

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 16, Issue 2, June 2025.
Abstract Prior disaster experiences often provide lessons for communities to respond to new disasters. In informal communities prone to disasters but conditioned within reactive disaster management regimes, residents and Community‐Based Organizations (CBOs) play immense roles in disaster risk reduction and response.

Toxicity of BaP exposure during embryonic stage in zebrafish: the mechanisms involved [PDF]

open access: yes, 2016
多环芳烃(PolycyclicAromaticHydrocarbon,PAH)是环境中一类分布广泛的持久性有机污染物。苯并(a)芘(Benzo(a)pyrene,BaP)作为代表性的PAH具有包括神经毒性和生殖毒性在内的多种毒性。截至目前,关于BaP神经毒性的研究大多集中于高浓度或短期的暴露实验,而环境水平浓度下、长期的BaP暴露是否能引起同样的神经毒性则研究得较少;此外,胚胎时期低浓度BaP暴露对成年阶段的神经毒性、生殖毒性效应及其机制研究更为少见。因此本研究以斑马鱼为模式动物,分别进行环境水平浓度 ...

Effect of Ba Zhu Decoction(BZD) on the related mechanisms of Aβ formation in 5xFAD transgenic mice [PDF]

open access: yes, 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 ...
