发帖数: 1211 | 3 Food intake is not the only source of cholesterol. Cholesterol is
synthesized in the liver from other metabolic products such as sugar (
glucose, starch) and protein. Statin is the most widely prescribed agent
that lowers cholesterol. It works by inhibiting the key enzyme that
synthesizes cholesterol in the liver.
So although healthy diet is critical, one sometimes need a little help. |

我是坚决反对warmer加热母乳的。
母乳最大的优点有2个。第一是抗体，第二才是好吸收。营养成分，配方奶不比母乳差-
人家配嘛。
但那个warmer很ws。在label上说对fomula和breast milk营养是安全的。没错。但更重
要的抗体呢？杀死好多了。warmer就回避了。

发帖数: 5444 | 12 前卫时尚的水瓶座
既是理想又保守的矛盾体，也是爽朗的现实主义者，前卫时尚的瓶子极赋创造力，
将前卫与流行真实的展现出来。透露着布鲁斯般忧伤的重金属是瓶子们最赋激情的演绎
方式。
代表音乐类型--Progressive Metal、Synth Pop
Progressive Metal即前卫金属，风格有别于传统重金属，在歌曲中采用大量复杂
华丽的编曲，或在歌词中传达出某些前进思想供听者一个想象思考的空间。
Synth Pop即合成流行，其中“Synth”，即Synthesizer，Synth Pop就是“由
Sythesizrs炮制出来的流行乐”，当然除Synthesizers外还会用上其他电子乐器如电脑
及鼓机等等。Synth Pop的特点是科技感强，有时会颇冰冷，歌曲多是“三分钟流行曲
”(3-minutes Pop)
代表人物--Guns N'Roses主唱W-Axl-Rose(罗斯)真名William-Bailey
枪炮与玫瑰乐队的主唱，音域宽广，尤其在高音部分挥洒自如。ROSE具有非凡的创
造才华他也是乐队的形象代表，特别受到女歌迷的狂热爱戴。

—为Tim Hunt学术报告的引言
当我的年龄接近于在座的多数时，我有个和你们一样的担心：最好的科学都已经做掉了
，我们没有赶上过去的好时代。
确实，很多进入科学不久的人，在经历最初的激动后，常常发现科学研究的日常有很多
重复工作：克隆基因、纯化蛋白
质、培养细胞、筛选突变…。一般来说，手头的工作好像远远不如听老师讲的科学发现
故事那么精彩、那么美妙。
不少学生会失望，可能还会转而埋怨：现代科学已经变质了，都是骗我们进来做苦力。
这不是新的现象，不仅你们现在，我们二三十年前，也有学生经常聚在一起说同样的话
。比如我在中国是1983年开始念
研究生，我的同学里就有很多这样的议论。
但是，事实上，我们今天的学术报告人，Tim Hunt博士，就是在1982年，做出他最重要
的工作（发现cyclin分子，
1983年发表）。也就是说，象我一样愚蠢和不敏感的人正在发表自以为是的高论的时候
，正是Tim这样的科学家，他们
有洞察力、有敏感性、或者有运气，正在做突破性的发现。
