As soon as there is a change in body mass change in percentage of fat lepton levels are very reactive to that.
因为只要身体质量发生变化体内的脂肪比例发生变化瘦素水平就会相应的调整
And it's difficult then to show an impact of sleep duration there have been epidemiology studies who have found reduced lepton levels in those with short sleep.
因此很难证明睡眠长短会造成什么影响有一些流行病学的研究发现对其他辅助因素进行了控制之后
After controlling for a number of cofactors Inaudible that's a very important and interesting question.
睡眠时间短的人 瘦素水平也低听不清这是一个重要而有趣的问题
And it has not been addressed I think I can share the one experience that there was a novel... Set a different knowledge and development.
我刚才没有讲我想我可以给大家分享一个经验这是另一套知识
That pharmaceutical company had noticed that there was a small decrease in BMI in those randomized to the active drug.
制药公司已经发现那些被随机分配到活性药物小组的人和分配到无效对照剂小组的人
As compared to the placebo and so they called me in to develop a protocol to examine that and then the upper management.
前者的身体质量指数更高所以他们叫我过去开发一个测试程序结果高级领导层
Decided not to continue the development and my project was in the trash can.
决定不将这项研究继续下去我的项目就被扔进了垃圾桶.
Thank you so much for that amazing talk your work is so important I was wondering if you could comment a little bit on any of these three periods of stress.
感谢你带给我们的这场令人惊叹的演讲 你的研究非常的重要我想请你评价一下三种持续时间不同的压力
