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 ...

Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Linchuang shenzangbing zazhi, 2018 膜性肾病(MN)是成人肾病综合征最常见的病理类型之一,以肾小球脏层上皮细胞下免疫复合物沉积、基底膜增厚及钉突形成为病理学特征。依据病因可分为特发性膜性肾病(IMN)和继发性膜性肾病(SMN)两类,其中IMN约占2/3,SMN约占1/3。研究表明,30%～40%的IMN患者可以自发缓解,1/3的患者将最终进展为终末期肾病 ...

Veterinary Dermatology, Volume 36, Issue 5, Page 621-629, October 2025.Background – Canine superficial bacterial folliculitis (SBF) is a common recurrent condition with a growing requirement for culture and susceptibility as a consequence of increased antimicrobial resistance and antimicrobial stewardship. Different opinions persist about the ideal technique for culture sample acquisition, which varies with lesion ...

Dermoscopic evaluation of normal canine skin with a handheld dermoscope
Veterinary Dermatology, Volume 36, Issue 5, Page 593-601, October 2025.Background – Dermoscopy is a noninvasive diagnostic tool that provides a magnified view of skin structures. While dermoscopy is described for certain canine dermatological diseases, large‐scale studies evaluating normal skin are lacking. Hypothesis/Objective – This study aimed to correlate dermoscopic findings with histopathological results in healthy ...

浙江大学学报. 医学版骨髓增生异常综合征是克隆性造血组织肿瘤，表现为慢性血细胞减少症伴细胞形态发育异常，易进展为骨髓衰竭或急性髓系白血病。贝赫切特综合征是一类特殊的系统性血管炎，主要表现为复发性口腔溃疡、皮肤损害、眼部炎症等。近年来，骨髓增生异常综合征合并贝赫切特综合征的病例报道增多，提示两者之间存在潜在的病理联系。免疫细胞的异常激活、细胞因子的异常分泌以及细胞遗传学改变等可能在骨髓增生异常综合征合并贝赫切特综合征的发病机制中起重要作用。目前，骨髓增生异常综合征合并贝赫切特综合征的治疗策略主要基于个体化原则，包括免疫抑制治疗、
