New Motivation for Self-Improvement
January 28, 2007 -- A dilemma facing millions of americans is getting a local look...
Plus, staying on your weight loss track...
If you resolved to trim down this year, but your motivation is lagging, here's some new inspiration.
Scientists at Oregon Health and Science University says it could turn back the clock on your immune system.
Disease-fighting T-cells in the blood tend to drop off as we age, making us more susceptible to illnesses.
But the oregon researchers found that monkeys on reduced calorie diets had more T-cells than those on traditional diets.
============================================================= Magnetic Stents:
A Drexel College of Medicine team is testing the power of magnets to eliminate some of the worries surrounding stents.
These tiny wire mesh tubes are implanted in the heart arteries of millions of Americans.
While the drug-coated versions are better at keeping arteries open, studies show they may also encourage blood clots, and trigger heart attacks.
Zachary Forbes, Ph. D., says, "We can target drugs through nanoparticles, and for the life of the stent in the body, treating it as many times as necessary if any complications should arise."
The magnetic current would be strong only where medication is needed, but not elsewhere, to attract it to the right place.
Dr. Forbes: "The amount of drug the body sees as a whole is drastically reduced by our method."
Dr. Forbes is doing tests on a variety of stent materials, as well as a variety of drugs that could be delivered this way.
He's even thinking about using the magnetic technique beyond stents, to other implants, such as joint replacements.
He believes antibiotics could be easily delivered to the sites after surgery, to cut down on post-surgical infections.
