美国暂停电话监控项目

思考 :

  1. FBI 是哪几个英文单词的缩写
  2. 奥巴马是鹰派还是自由派
  3. 爱国者法案和美国自由法之间是什么关系
  4. 文中标红斜体字的意思

眼看大限将至,美国国安局做好最坏打算,开始关闭用于监控的服务器,以便在失效期到来时停止相关活动。

Blood Pressure Vaccine Lengthens Rat Lives

Some 70 million American adults have high blood pressure. Three quarters of them rely on medication to keep the condition in check. But you've got to remember to actually take the daily dose. Now researchers have devised a longer-lasting alternative: a vaccine to lower blood pressure - for rats, at least.

Scientists jabbed hypertensive rats with three doses of the formulation. It's a DNA vaccine - containing DNA fragments from angiotensin II - a hormone that boosts blood pressure, as well as fragments from hepatitis B, to guarantee the immune system's attention. Cells suck up the vaccine's DNA, and start pumping out the proteins the DNA codes for. When the host's defenses gets a whiff of the proteins, it reacts. It really revs up against the hepatitis B fragments. And while it's at it, it starts taking out some angiotensin II as well.
