Dr. Susan Sharma: This is insidermedicine in 60. 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 pills that slow aging and prevent 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 don'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 chances 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 ounce glass of red wine per day had a 15% reduction in their sugar levels. No effect was noted in the control group. For insidermedicine in 60, I'm Dr. Susan Sharma.
