Veterinary Dermatology, Volume 37, Issue 2, Page 236-246, April 2026.Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...

自发性高血压大鼠TGFβ1/ Smad7通路与心室纤维化的关系
Zhongshan Daxue xuebao. Yixue kexue ban, 2008 [目的]探讨自发性高血压大鼠心室纤维化过程中TGFβ1和其下游分子smad7蛋白的表达规律。[方法]雄性自发性高血压大鼠（SHR）14只随机分为2组，SHR 22周龄组和SHR 14周龄组，另14只WKY大鼠也分为WKY大鼠22周龄组和WKY大鼠14周龄组。在实验动物14周龄和22周龄时，分别测定血压、心室质量指数；以氯胺T法测定心肌羟脯氨酸的含量，免疫组化测定Ⅰ型和Ⅲ型胶原在心肌组织中的表达水平；RT-PCR和Western-blot测定心肌中TGFβ1和其下游分子smad7的表达。[结果 ...
