Genome-Based Medical Choices Draw Nearer

It’s the kind of thing we can look forward to more in the coming years: personalized drug regimens based on our individual DNA.  An example of this new kind of personalized medicine is illustrated by a study in the January 23rd issue of the Journal of the American Medical Association.  Researchers found that hypertension patients had better results with different drugs depending on the patient’s genetic profiles.  Currently, for the most part, doctors will put people with high blood pressure on a standard bp medication and see if it works.  If it doesn’t, they’ll try another drug, until this trial and error system finds a good one.  But genetic profiling could let physicians know immediately which patient will respond to which drug.

This study of genetics and bp meds included over 38,000 subjects with high blood pressure in the US and Canada who are taking part in a large multicenter trial.  With personalized genomic sequencing becoming affordable in the next few years, many of us should finally know in advance, not just our risks for disease, but what medications will be most effective.

PATPAT,已经比本科版好多了,本科版最快最快的时候一天也不到两页帖子.通常一天就半页左右,甚至更少.
每次在页面最下面看到有很多不认识的ID看帖,但总就那么几个人说话.:(

Snake Hearing Is Connected To The Jawbone

Most schoolkids know that snakes can “see” with their noses. Vipers in particular have these organs on their noggins that allow them to see heat, which helps them find their warm-blooded prey. If that’s not wild enough for you, now physicists from Germany and Kansas say that snakes can hear with their jaws, an idea they present in an upcoming issue of Physical Review Letters.

See, snakes don’t have actual ears. At least not on the outside. But they do have fully formed inner ear systems, complete with a cochlea, the fluid-filled bone that harvests sound. But in snakes, the cochlea is connected to…the jawbone. So, if you walk past a snake that’s resting with its head on the ground, the vibrations from your footsteps jiggle the snake’s jaw, which shakes the snake’s cochlea, so the snake can hear you move. In fact, the physicists found that this whole listening-with-your-mouth setup can sense even the tiny vibrations made by scampering rodents or other small prey. And because snakes can unhinge their jaws one side at a time, they may be able to hear in stereo. Which means that tapping on the glass of the rattlesnake exhibit is actually twice as annoying as anyone ever realized.
