HealthWise at 5 From 3.3

  • New HIV Monitor Test

There's a new tool in the fight against AIDS. A newly approved FDA test monitors the viral load of patients with HIV. The Amplicor HIV-1 monitor test uses a special technology to measure how much of the virus is circulating in a patient's blood stream. Researchers say the device is 99.9% accurate and will help doctors know whether a patient's treatment is working.

  • Your Family Appetite

Having trouble saying no to that third piece of pizza? Blame genetics. A study published in the Journal of Clinical Nutrition says a certain chromosome could be the reason. Researchers say the chromosome acts as a growth hormone receptor and stimulates hunger. It apparently has different parts that might influence eating behaviors such as when to decline more food. More research on this chromosome could lead to better treatment of eating disorders and obesity.

  • Synthetic Blood Vessels

Heart surgery patients who need extra blood vessels might end up with a natural one right off the shelf thanks to biomedical researchers at Virginia Commonwealth University. The blood vessel-growing technique involves electro-spinning a form, or scaffold, with collagen. The collagen scaffold is then "seeded" with smooth muscle cells and in a few weeks, a natural blood vessel is ready for use. The VCU researchers say the technology could also be used to regenerate skin, bone, nerves and muscles.
