蜗牛分泌的天然胰岛素药效好
蜗牛 分泌 天然胰岛素

美国犹他大学官网2016年9月12日发布公告称，该校研究人员与澳大利亚同行合作，在蜗牛捕食时产生的毒液中发现了胰岛素分子结构，这种天然胰岛素能在短短5分钟内调节血糖水平，而目前最快的人工胰岛素起效时间是15分钟。人体胰岛素是由胰腺分泌的与葡萄糖摄取相关的一种激素，它内含A区和B区。糖尿病一般因胰腺功能受损无法正常分泌胰岛素所致，目前最有效的疗法就是注射人工胰岛素。但胰岛素内的B区部分会造成胰岛素分...

一种食用蘑蛋白质或可抑制流感
食用蘑蛋白质 抑制流感

日本理化学研究所主任研究员小林俊秀领导的一个国际研究小组发现，食用蘑舞茸的一种蛋白质能够抑制流感病毒的增殖。这一发现对于开发设计抗流感药物有重要意义。细胞膜上的脂质筏是一些直径约20至200纳米的微小区域，富含鞘磷脂和胆固醇，起到信号转导和跨膜运输作用，且在病毒和细菌感染的过程中扮演非常重要的角色。但由于缺乏对脂质筏的标记手段，科研人员对其实际情况并不掌握。

你相信么，鱼也会患上关节炎！美国南加州大学研究人员领导的一项研究发现，地球上早期出现的硬骨鱼很容易患上关节炎。研究人员表示，对鱼类关节炎患病机制的研究，或许会加速人类关节炎预防和治疗手段的研究进程。长有四肢的骨脊椎动物，如人类，都是从肉鳍类鱼进化而来。在生物进化过程中，为更适应生存环境，陆上脊椎动物很早就进化出了滑膜关节，以便移动，如人类的膝盖和臀部都有滑膜关节，这些部位也很容易患上骨关节炎。而在...
