An Extracellular Pore‑Targeting Peptide Defines a Designable Allosteric Site in TRPV2
Advanced Science, EarlyView.Structure‐guided peptide engineering yields Depiv2, a highly potent and subtype‐selective TRPV2 inhibitor that binds to the extracellular pore and remodels it into a closed, non‐conductive state. Depiv2 suppresses pathological cardiac hypertrophy, establishing the TRPV2 outer pore as a designable interface for selective peptide modulation.

体外培育牛黄通过调控小胶质细胞极化及炎症小体活性干预脑缺血再灌注损伤
浙江大学学报. 医学版目的：探讨体外培育牛黄（ICCB）减轻脑缺血再灌注损伤（CIRI）的机制。方法：分别构建大脑中动脉阻塞（MCAO）大鼠模型和氧糖剥夺/再灌注（OGD/R）BV2细胞模型。其中，大鼠模型于脑缺血1.5 h再灌注72 h后进行改良的神经损伤严重程度评分（mNSS），并测定脑组织含水量和脑梗死体积；苏木精-伊红染色法检测大脑皮层及海马CA1区组织结构病理变化；免疫荧光法检测皮层小胶质细胞极化情况和NOD样受体热蛋白结构域相关蛋白（NLRP）3炎症小体的表达情况。BV2细胞于氧糖剥夺0.5 h再灌注24 h后 ...

, 2013 武俠小說的世界，有「江湖」、「綠林」、「武林」三種慣稱。「江湖」強調了它的變動性及危險性，「綠林」顯示了它的違法及不合理性，「武林」則限制了他屬於「武人」的屬性。三者各有側重，各有淵源，但唯有等量齊觀，才能真正掌握到武俠小說虛構的「江湖世界」特性。 虛構的「江湖世界」，基本上以真實存在的江湖為藍本，透過闌入、化入的手法，構築出一個自足而完滿的奇異世界，具有濃厚的理想寄託。 金庸小說的江湖世界，以教門、幫派、武學門派為三大支柱。明教、丐幫、少林三大派的凸顯，展示出金庸因襲與開創的「江湖」特色 ...
