髓系细胞触发受体２在认知功能障碍中相关机制的研究进展 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban神经免疫系统对中枢神经系统的发育、衰老和损伤至关重要，逐渐成为人们研究的热点。髓系细胞触发受体２（TREM2）是免疫球蛋白超家族的一种跨膜受体，在中枢神经系统中主要表达于小胶质细胞。越来越多的研究表明，靶向TREM2对改善阿尔兹海默症、血管性痴呆、帕金森病、术后认知功能障碍、肥胖等疾病相关的认知功能障碍有很大的潜力。然而，其在认知功能障碍中的具体作用尚缺乏系统性的总结。故本文综述了TREM2在认知功能障碍中相关机制的最新研究进展，以期为认知功能障碍的治疗提供新的靶点。

, 2005 目的:研究广西巴马地区长寿老人载脂蛋白E（ApoE）基因多态性的分布及其与认知功能改变的关系。方法:采用简易精神状态量表（MMSE）对112例90岁以上广西巴马地区长寿老人进行认知功能检查,并用限制性酶切片段长度多态性分析（PCR-RFLP）方法进行ApoE 基因分型。根据MMSE 得分将研究对象分为认知功能正常组和认知功能障碍组.比较两组人群的基因型、基因频率的分布特征。结果:巴马长寿老人中发生认知功能障碍者占14.29%。长寿老人中ApoEε3/3基因型分布的百分比最大,其次是ε2/3,而ε4 ...

Co‐Teaching in a Virtual Intensive Study Language Programme: Insights From Team Ethnography
International Journal of Applied Linguistics, EarlyView.ABSTRACT As virtual study abroad becomes an increasingly important form of international education, little is known about how transnational teaching is organised and sustained across institutions. Using activity theory as an analytical framework and team ethnography as methodology, this study examines a virtual intensive study (VIS) programme delivered

International Journal of Applied Linguistics, EarlyView.ABSTRACT Self‐directed Learning (SDL) is an important skill for learners of all ages and phases of life. Generative AI facilitates self‐directed second language (L2) learning by providing interactive, personalised access to online resources. However, existing research on AI‐assisted self‐directed L2 learning focuses on adult learners in higher ...

Canine Distemper Virus Research in China and Future Directions for Conservation 中国犬瘟热病毒研究现状与保护策略展望
Integrative Conservation, Volume 5, Issue 3, Page 268-280, September 2026.ABSTRACT Canine distemper is a highly contagious, severe disease caused by the canine distemper virus (CDV). With a worldwide distribution and ever‐expanding list of susceptible hosts, CDV poses a growing risk for many threatened wildlife species, both in captivity and their native habitats. As a megadiverse country, China is home to myriad endemic and

Exploring legal‐ and health‐risk messaging to reduce demand for elephant skin
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Asian elephants (Elephas maximus) are poached for an illegal trade in their skins, which are used in traditional medicine in Africa and Asia. We explored whether messages about the legal and health risks of using elephant skin for medicinal purposes (stomach illness) could reduce such consumption.

The Effects of Policy Success Versus Failure Narratives
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT While public policies usually have mixed effects, succeeding at some aspects and failing at others, this nuance is often lost in public discourse when political actors like advocacy groups and politicians strategically emphasize either the successes or failures of particular policies.
