Sex-biased autophagy as a potential mechanism mediating sex differences in ischemic stroke outcome

Stroke is the second leading cause of death and a major cause of disability worldwide, and biological sex is an important determining factor in stroke incidence and pathology. From childhood through adulthood, men have a higher incidence of stroke compared with women. Abundant research has confirmed the beneficial effects of estrogen in experimental ischemic stroke but genetic factors such as the X-chromosome complement can also play an important role in determining sex differences in stroke.

Glial regenerative response in the imaginal discs of Drosophila melanogaster

<正>Glial cells play a key role during nervous system development and actively participate in all the cellular processes involved in maintaining its structural robustness and functional plasticity.In response to neuronal damage,glial cells proliferate,migrate to the injured region and change their morphology,function,and behavior     

Gangliosides in nervous system development,regeneration, and pathologies

Gangliosides, sialic acid-containing sphingolipids, are major constituents of neuronal membranes. According to the number of sialic acids and the structure of the oligosaccharide chain, gangliosides can be classified as simple or complex and grouped in different ganglio-series. Hundreds of gangliosides have been identified in vertebrate cells, with different expression patterns during development and related to several physiological processes, especially in the nervous system. While GD3 and its ...     

益肾通督电针疗法对女性创伤后应激障碍的临床观察

目的观察益肾通督电针疗法对于女性创伤后应激障碍(PTSD)的临床疗效。方法将65例女性PTSD患者随机分为电针治疗组和单纯西药对照组连续治疗2个月,在治疗前、后分别对患者的症状自评量表(SCL-90)、雌二醇、皮质醇等水平进行测定。结果治疗前、后评分总体上组间效应不显著(P <0. 05)、但电针组在SCL-90躯体化症状、焦虑评分较单纯西药对照组有明显改善(P <0. 05)。结论益肾通督电针疗法治疗女性PTSD患者的总体疗效与单纯西药对照组疗效大致相仿,电针疗法对于改善患者临床常见症状疗效确切且副作用小,价格相对低廉,患者依从性较好。
