阿尔茨海默氏症或将迎来新疗法
阿尔茨海默氏症 新疗法
2016/6/8
哈佛大学医学院和麻省综合医院的研究人员日前发现,β淀粉样蛋白在保护大脑免受细菌入侵过程中发挥重要作用:适量蛋白可消灭有害细菌,但免疫系统功能一旦下降,反而会产生大量β淀粉样蛋白导致阿尔茨海默氏症。发表在《科学转化医学》杂志上的研究结果,或将改变这一老年病的治疗方向。

新型动脉“速生”比现有技术快10倍 可用于测试药物效果
新型动脉速生 快10倍 测试药物
2016/2/25
据美国杜克大学最新消息,该校工程师开发出一种迅速制造人工动脉的新技术,比目前用组织工程技术制造血管要快10倍,该人工动脉还能自然产生维持动脉正常工作所需的生化信号。
动脉壁有多层细胞,内皮细胞在最里面,与血液循环相互作用,间层由平滑肌细胞构成,帮助控制血流和血压。这两层通过一套化学信号来沟通,控制着血管系统对药物、体育锻炼等外部刺激的反应。研究团队造出了包含两层细胞的人工动脉,并证明了这两层之间...
