氧化脂质在脑血管病中的研究进展 Advances of Oxylipins in Cerebrovascular Diseases
Zhongguo cuzhong zazhi氧化脂质是由多不饱和脂肪酸氧化产生的生物活性脂质。近年来，越来越多的研究证明氧化脂质可通过炎症反应、氧化应激、细胞凋亡、血管稳态等多种机制影响脑血管病的发生发展。另外，基于代谢组学的临床研究发现氧化脂质在脑血管病不同表型或预后患者中的水平存在差异。研究氧化脂质在脑血管病中的作用有助于为脑血管病的诊断、治疗及预防提供新思路、新方法。 Abstract: Oxylipins are bioactive lipids formed by the oxidation of polyunsaturated ...

Investigate the Effect of Resveratrol on Postovulatory Aging of Mouse Oocytes [PDF]
, 2016 大多数辅助生殖技术在体外操作，随着操作时间的延长，未受精的第二次减数分裂中期的卵母细胞会经历老化的过程，此过程限制了卵母细胞发展的潜力和受精的能力，因此如何延缓卵母细胞的老化为操作争取更多的时间是提高辅助生殖技术成功率的关键。然而，至今仍没有合适的方法能克服卵母细胞在体外发生的老化。本文的研究目的是探讨白藜芦醇是否可以改善排卵后老化的卵母细胞在体外发生的不良结局，之前有研究表明白藜芦醇可以提高不同物种在体外受精的概率。我们用小鼠第二次减数分裂中期的卵母细胞作为对照组 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 1988 硒(Se)是人体必需微量元素,在营养生理学允许量范围内,硒能阻止或延缓病毒、化学致癌物对肿瘤的诱发而产生的致癌作用。谷胱甘肽过氧化物酶(GSH—PX)是硒依赖性的,硒作为谷胱甘肽过氧化物酶的一种重要成分来还原脂质氢过氧化物,使还原型谷胱甘肽(GSH)转变成氧化型谷胱甘肽(GSSG),这样就可破坏脂质氢过氧化物对机体带来的损害,保护细胞膜和组织对抗脂质过氧化反应所引起的破坏作用,维持细胞正常的生物功能。
