俄罗斯科学家 控制皮肤癌 纳米凝胶粒子
2017/2/21
俄罗斯科学院生物化学物理研究所最近研制出纳米凝胶粒子，可以用来封裹各种对人体有益的物质，比如：对心脏、大脑和血管有益的不饱和脂肪酸，以及各种草本抗氧化剂。该项成果是研究人员在研究水果和某些植物的叶子里含有多种草本抗氧剂的有用属性时额外发现的，并成功试制出了这种粒子。
For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, puttin...

一种蛋白事关新生儿呼吸调控
蛋白 新生儿 呼吸
2016/12/23
英国《自然》杂志2016年12月21日在线发表的一篇论文报告称，科学家发现Piezo2蛋白在小鼠中阻止了肺部过度扩张的发生。这一发现将为一些呼吸道障碍，比如睡眠呼吸暂停和慢性阻塞性肺病提供全新见解。大多数哺乳动物通过一种被称为“赫—鲍二氏反射”的反应来防止肺部过度扩张，这种反射会使吸气立刻停止。然而，人们并不清楚它的具体工作机制。此前，并没有Piezo2蛋白与呼吸系统相关的发现。
