...about 15 minutes, but experts say that's still plenty of time to spot a problem. Navigator's repeated readings let patients know when their glucose levels are trending dangerously high or low--or holding steady. And that's particularly liberating for Type 1 diabetics, who cannot make enough insulin to harness their sugar levels and therefore need to maintain strict control over their blood sugar. It's also helpful for Type 2 diabetics, whose bodies cannot process the insulin they have. By knowing their sugar levels, they can plan how much to eat or exercise (both of which change...
...University of California, San Francisco, meanwhile, molecular geneticist Cynthia Kenyon is taking a different approach to aging research, identifying a number of genes in roundworms that help stave off disease and extend life. One such gene directs the action of a receptor for insulin and an insulin-like hormone called IGF1, and by manipulating it along with other genes, she can increase the worms' life-span sixfold. "It's not so much that they're just living longer," she says. "What's remarkable about these worms is how healthy they...
...thighs or hips?increases the chances of developing heart disease, high blood pressure and diabetes. Apparently, abdominal fat doesn't just lie there and jiggle. It actively promotes ill health by, among other things, pumping out inflammatory proteins and interfering with the body's ability to use insulin...
...recently demonstrated in South Korea, he plans to create embryos by injecting a patient's DNA into an egg from which the genetic material has been removed. He then hopes to harvest the embryonic stem cells--which can develop into almost any organ--and coax them to produce insulin in diabetics. Stem cells may also hold promise for victims of Parkinson's and heart disease. Controversy has arisen from the fact that he is creating and discarding embryos. For many people, that is morally unacceptable. In the U.S., the Bush Administration has limited funding for stem-cell research for that...
...thighs or hips - increases the chances of developing heart disease, high blood pressure and diabetes. Apparently, abdominal fat doesn't just lie there and jiggle. It actively promotes ill health by, among other things, pumping out inflammatory proteins and interfering with the body's ability to use insulin. So it seemed plausible to many physicians that surgically removing belly fat by liposuction could give patients a double benefit: a slimmer physique and a better metabolic profile. That's why there was such disappointment with the news, reported recently in the New England Journal of Medicine, that unlike losing weight...
