http://en.wikipedia.org/wiki/Ethidium_bromide#Health_risks
The National Toxicology Program states it is nonmutagenic in rats and mice.[
10] These results are supported by a subchronic carcinogenicity study in
mice conducted at the university of Düsseldorf where also no mutagenic
effects could be detected.[11] Ethidium bromide (Homidium brand) use in
animals to treat trypanosome infection suggests that toxicity and
mutagenicity are not high. Studies have been conducted in animals to

几个解决方案(第三个我试过不work):
1 花钱, app store 买id3mod2。不贵,有漂亮UI界面。
2 不花钱,
下载mutagen: http://code.google.com/p/mutagen/
安装mutagen (我用osx)
解压文件后到解压目录里面运行
./setup.py build
sudo ./setup.py install
到要转换的歌曲目录下
mid3iconv -e gbk *.mp3
搞定!(到itune里面重新倒入发现没有问题)

3 看到有人说在itune里面convert id3也可以,自己试验发现该完了没反应。
对于每天在命令行敲命令的人来说2是最好的选择。速度很快,而且不用花钱。
我花了半个小时搞定的,时间上面投资比买id3mod2贵多了。写下过程,希望帮助后人
节省时间。
按照我写的做,大概几分钟可以搞定。买id3mod2再安装,估计也要花那么多时间。

An extraordinarily large volume of animal data has been compiled to evaluate
the carcinogenic potential of glyphosate. The expected normal biological
variability for spontaneous tumor formation is reflected across this
extensive data set (Tables 20–23). However, no specific neoplasm stands out
as a consequence of glyphosate exposures. While some individual studies may
note an increase in a specific neoplasm at the high dose, the pooled data

来自主题: PennySaver版 - [科普] 瘦肉精各国用量限定
瘦肉精是一类动物用药,有数种药物被称为瘦肉精,例如莱克多巴胺(Ractopamine)及克伦特
罗(Clenbuterol)等。将瘦肉精添加于饲料中,可以增加动物的瘦肉量、减少饲料使用、使肉
品提早上市、降低成本。但因为考虑对人体会产生副作用,各国开放使用的标准不一。
瘦肉精是一类药物,而不是一种特定的物质,是指能够促进瘦肉生长的饲料添加剂。任何能够
促进瘦肉生长、抑制肥肉生长的物质都可以叫做“瘦肉精”。
目前,能够实现这种功能的物质是一类叫做β-促效剂(β-agonist)的药物,比如在中国造
成中毒的克伦特罗(clenbuterol)和美国允许使用的雷托巴胺(Ractopamine)。
瘦肉精在上海曾经引发了几百人的中毒事件。而在台湾,由于从美国进口的猪肉里含有瘦肉
精,几乎挑起一场政治争端。奇怪的是,在美国、加拿大、新西兰等国,瘦肉精这类物质的使用却
是合法的。在中国,通常所说的“瘦肉精”则是指克伦特罗。它曾经作为药物用于治疗支气管哮喘,
后由于其副作用太大而遭禁用。
其它这样类似药物还有沙丁胺醇(Salbutamol)和特布他林(Terbutaline)等,同样能起

because the mammary glands are developing in young women, which means active

higher estrogen is a risk factor, because it promotes cell division in those

你東施效顰得很差勁。
進化論的突變有很多種, spontaneous mutation 是其中一種。
Four classes of mutations are (1) spontaneous mutations (molecular decay), (
2) mutations due to error prone replication by-pass of naturally occurring
DNA damage (also called error prone translesion synthesis), (3) errors
introduced during DNA repair, and (4) induced mutations caused by mutagens.
你問題根本不是是非題, 你要是問『spontaneous mutation 會不會造成演化』,答案
是『會』
要是問『進化論的突變是不是只有 spontaneous mutation}』,答案是『不是』,因為

很简单,候选人的学术成就是否在其领域代表了最高水平。
至于学术成就如何评价,以前是在国内最高就行。现在与国际接轨,科学院应该更强调
原创性,工程院更强调。。。(我不是搞工科的,觉得应该更着重解决实际的问题,和

你提供的这片文章太烂了,居然用1-10000ppm的剂量。1ppm glyphosate大概是6uM,对
于生理浓度来说是非常非常高的了,10000ppm更是没有可能在正常生理情况下出现。可
以这么说就算是10000ppm的糖都可能对细胞产生很强的伤害。我看到文章里提到1ppm是
人尿液中的浓度,我仔细找了找,文中并没有提出reference,有一个地方模模糊糊的
有一个引用,查了一下引文,人家测的在施用农药的工人以及家人中 glyphosate在尿中的浓度是ppb级别的,最高也只有233ppb,平均是3ppb,比1ppm差的
