The Expression of PolySia/TriSia Associated Proteins and Genes on Developing Brain and the Effect of Dietary Sialic Acid Intervention in Piglets [PDF]
, 2015 摘要 研究背景：唾液酸（Sialicacid,Sia）是一类九碳单糖神经氨酸的总称，在细胞表面发挥其多种生物学功能。在体内，Sia通常以游离唾液酸、聚唾液酸（多聚/寡聚）、唾液酸衍生物（糖蛋白，糖脂）这三种形式存在。多聚唾液酸（polySialicacid,ploySia），一种唾液酸残基通过α2-8键连接而成的线性聚合物，广泛分布于在哺乳动物神经系统中，它的主要蛋白载体是神经细胞粘附因子（Neuralcelladhesionmolecule,NCAM）。PolySia-NCAM在细胞迁移、神经突生长 ...

Vulnerability of tropical fish communities across depth in the central Indian Ocean
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

The neuronal cell cycle regulation mechanism and related animal model in Alzheimer’s disease [PDF]
, 2015 阿尔茨海默病（Alzheimer’sDisease，AD）是一种与年龄相关的神经退行性疾病，它的主要临床表现是记忆和认知功能的逐渐衰退。AD是一种严重影响人类健康的神经退行性疾病，至今仍未找到有效的治疗方法。因此从预防和早期治疗角度考虑，对于AD早期病理变化的研究就十分重要。成熟神经元处于细胞周期静止期，而在AD中，大量神经元的细胞周期被重新激活，但这些神经元不会再分裂而是最终走向了凋亡，这是目前在AD小鼠模型中已知最早的细胞功能紊乱。但对细胞周期重新激活导致神经元凋亡的机制目前还不清楚 ...

Using online reports of seahorse seizures to track their illegal trade
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

Improvements for better scaling of locally managed marine areas
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract To protect and restore ecosystems at the speed and scale required to meet current environmental challenges, a greater understanding of how conservation initiatives spread from existing to new adopters is required. According to the diffusion of innovation theory, positive adopter‐to‐peer communication is a powerful driver of innovation spread ...

Integrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.
