Longevity Gene, Cell Phone Affects Hearing, Cardiac Rehab, Wine & Type 2 Diabetes

(September 21, 2007 - Insidermedicine) From Boston - While cutting calories by 30 to 40% has been shown to increase longevity, Harvard researchers may have now found the reason why. Studying the livers of mice who had fasted for a few days, the researchers noted the activation of 2 genes, SIRT3 and SIRT4. These genes influence the mitochondria to become more efficient. The research could lead to a pill that slows aging and prevents ailments such as cataracts, heart disease, and Alzheimer's.

From Washington - While cell phones don't raise the risk for brain cancer, they may affect hearing. In a study comparing 100 cell phone users to those who didn't use them, those who used their phones for more than 60 minutes per day for over 4 years had a noticeable loss of hearing at higher frequencies. Signs of damage include warming of the ear or a sense of fullness or ringing.

From Rochester - Unfortunately, many who have suffered from a heart attack are not being referred to cardiac rehabilitation, despite the fact that it can lower the chance of death from another heart attack by 25%. Cardiac rehab includes evaluation to identify and modify risk factors, the supervision of exercise, nutritional modification, and counseling.

And finally, from Israel - A glass of pinot noir may be just what the doctor ordered for those with type 2 diabetes. Researchers showed that diabetics randomized to drink a 5 oz glass of red wine per day had a 15% reduction in their sugar levels. No effect was noted in the control group.
