来自主题: Fishing版 - 美国的淡水鱼怎么吃安全

谢谢你的信息。
看起来蛮吓人啊,又是二恶英,又是PCB。
我们常钓鱼的那些点,从上面上回我去的蚊子岛,到海狼公园,全在这个圈子里面啊。
建议的是成人一个月只能吃8盎司,怀孕妇女和12岁以下儿童不该吃。
正好想到那些一COOLER一COOLER往家里搬鱼的,那不是得吃出问题来??
看来海狼公园是不敢去了。东湾和西湾看起来好一点,只是建议猫鱼不能吃。
那以后不是得往西南边转移,去MATAGORDA湾那边?
可是那边又有一个核电站。

问题是这转基因咋看着就是一种基因污染。 种子撒在哪里就把土壤破坏到那里是一个
方面。 同时还有一个问题就是你转一个抗草基因,不一定抗虫。 可你转多个基因的话
就真不知道是粮食,毒草还是鸦片什么的了。
孟山都的招牌除草剂 roundup 当中据说有一种PCBs, Polychlorinated biphenyls,
那是一种严重危害生命的东西,鸭子扔到被PCBs污染的水中3.5秒就挂了。 假如这种生
物活体基因转入植物的话,就不明白会产生什么结果了。

Fact or Fiction: Can You Really Sweat Out Toxins?
There are plenty of good reasons to work up a sweat. Detoxifying your body
isn’t one of them.
Sweating is a bodily function that used to be taboo, with women in
particular being told they don’t sweat, they glow. But look at any fashion
magazine or beauty blog today, and you’ll find that sweat is in style. From
infrared saunas to hot yoga, towel-soaking activities are being touted not
only as relaxation tools, but also as ways t... 阅读全帖

Salmon and Beef: What's Safe to Eat?
Amid the flurry of headlines about the food industry, it's a challenge to
figure out what is safe to eat: Is mad cow disease a real threat? Does
farmed salmon cause cancer?
Many consumers are racing to buy organic foods to avoid potential toxins in
their grocery carts. But are we overreacting, or is there really cause to
shun our food supply?
When it comes to two of the most recent foods called into question -- beef
and salmon -- it boils down to a matter of ... 阅读全帖

i just saw this----Contaminants, like mercury and PCBs (
polychlorinated biphenyls), which can affect the brain and cause learning
and behavior problems, lurk in many fish and shellfish. Some species contain
very high levels; others have only trace amounts.
but it was generally speaking of all fishes, it didn't specify the

Deli Meat: Deli meats have been known to be contaminated with listeria,
which can cause miscarriage. Listeria has the ability to cross the placenta
and may infect the baby leading to infection or blood poisoning, which may
be life-threatening. If you are pregnant and you are considering eating deli
meats, make certain that you reheat the meat until it is steaming.
Fish with Mercury: Fish that contain high levels of mercury should be
avoided. Mercury consumed during pregnancy has been linked to d... 阅读全帖

来自主题: Chicago版 - 有对fish oil有研究的同学么?
What It Is:
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two principal
fatty acids found in fish and krill. They belong to a family of nutrients
known as omega-3 fatty acids. DHA can also be obtained from other marine
sources, such as algae (algal oil). EPA and DHA are polyunsaturated fats ("
good" fats, as opposed to saturated fats which are thought to increase the
risk of heart disease). The body can only manufacture limited amounts of EPA
and DHA from the essential fatty aci... 阅读全帖

Fish Consumption Advisory
Fish is high in protein, an excellent source of B-vitamins and trace minerals,
low in fat, and some fish are rich in omega-3 fatty acids. Omega-3's are "
good" fats that may help prevent heart disease.
However, fish can contain contaminants like mercury, PCB's (polychlorinated
biphenyls) or dioxins that may harm health. Mercury can damage the nervous
system and kidneys. Along with PCB's, it may cause developmental problems in
children. PCB's and dioxins may cause cancer

PCB levels lead to warning on bluefish, striped bass
From BDN Staff and Wire Reports
Maine and six other East Coast states are advising pregnant women and
young children to avoid eating striped bass and large bluefish caught
recreationally in state waters because of high PCB levels in the
migratory fish.
PCBs — polychlorinated biphenyls — are released into the environment
from certain coolants, fluorescent lights, hydraulic oils, electrical
equipment and other sources. They accumulate in cert

来自主题: Fishing版 - 吃鱼的选择
吃什么鱼,是大多数钓鱼人面对的一个问题。很多传说中的海鲜与高寿命,在现代医学
里往往是把鱼身体里的不饱和脂肪酸和心血管疾病联系在一起的,这就是很多科普文章
里提到的omega-3.其实,鱼肉的选择,除了omega-3,对钓鱼人来讲,还涉及现代生活带
来的污染问题。怎么选择这些不同的鱼种,不同的水体,其实也是我们钓鱼人值得考虑
的问题。我今天说说我的考虑。
我喜欢上网读资料。这个鱼类的污染,基本分两大类:1。mercury(水银或汞)--大多
数鱼身体里的mercury是水中天然来的,在鱼体内以二甲基汞的形式存在。以往观点认
为二甲基汞对人没有害,但现在更流行的观点是有害。我们就以有害来讨论吧。所有的
鱼都会从水中得到汞,并且是进入体内就不会排出来。但天然水中汞含量有限,所以,
很多素食的鱼体内不会太高。汞含量高的鱼往往是吃鱼的鱼,它们从其它鱼身体里得到
汞,并不断累积。2。人类活动带来的污染--工业生活农药化肥等等,Polychlorinated
biphenyls(PCB)可能是谈论最多的,主要是因为它(们)的应用太广泛,到了有人的
地方就有PCB的地步。
所有动物体内都有脂肪,它可... 阅读全帖

Crystal structures of Bcl-xL with 118 (PDB entry 2YXJ) and 4 were used to
model the binding poses of our designed compounds with Bcl-xL. In the
binding models, the structure of Bcl-xL in complex with 4 was superimposed
on that of Bcl-xL in complex with 1. The core scaffold of 4 then replaced

来自主题: Pharmaceutical版 - 将来哪类药最有前景?
An Abbott scientist made a seminar in our univ on the development of bcl-2
inhibitor. He ever mentioned that ABT-737 has already entered phase I
clinical trial.
If it is not ABT-737, then which one has already entered? Could you tell me?
Thanks!
I do not like the biphenyl, sulfonyl group and nitro-benzene substructure in
ABT-737. It might be such groups cause some side toxicities or bad
bioavailability profile and Abbott finally decided to advance another
compound into clinical trials.
