Preventing hearts from aging

Scientists prevented age-related changes in the hearts of mice and preserved heart function by suppressing a form of the PI3K gene, in a study reported in Circulation: Journal of the American Heart Association.


Quote
The Japanese researchers compared aged mice with a functional p110α to aged mice with suppressed p110α and found that mice with the suppressed gene had:

    * improved cardiac function;
    * less fibrosis (fibrosis causes the heart to lose flexibility);
    * fewer biological markers of aging; and
    * a pattern of cardiac gene expression like that of younger mice.

“This study showed that aging of the heart can be prevented by modifying the function of insulin and paves the way to preventing age-associated susceptibility to heart failure,” Shioi said.

I believe truth and principle do matter. If you have to sacrifice them to get the results you want, then the results aren't worth it.

Fortunately, I was a SNCO in the Air Force, and had my heart removed at the NCO Academy..just ask any of my former airmen   ;D

Now now, fightin's out of style here...

One must remember, I volunteered in 1973 to avoid the draft..and found I liked the lifestyle..

And I've never been afraid to make a decision, right or wrong..I preferred to lead, not rule..

Can't say how it is in the USAF these days, even though I work at Offutt..most of the base has gone civil service (we're contractors at the PMEL), and the few military I do interface with are usually the test equipment monitors

Take care..and I do appreciate you serving
