AIDS
HIV :: Cornell researcher helping develop quick, cheap HIV AIDS test
A Cornell researcher is working to help develop a quick, simple and cheap immune-system test for people in the developing world. It could help HIV/AIDS sufferers in the poorest countries get appropriate treatment to extend their lives, possibly by as much as 10 to 15 years.

Osteoporosis :: Estrogen helps in protecting bone avoiding osteoporosis
Researchers at the University at Buffalo have described a novel pathway by which estradiol, the primary estrogen in humans, aids in maintaining bone density, a function critical to avoiding osteoporosis.
Stroke :: MIT brace aids stroke recovery
At age 32, Maggie Fermental suffered a stroke that left her right side paralyzed. After a year and a half of conventional therapy with minimal results, she tried a new kind of robotic therapy developed by MIT engineers. A study to appear in the April 2007 issue of the American Journal of Physical Medicine & Rehabilitation shows that the device, which helped Fermental, also had positive results for five other severe stroke patients in a pilot clinical trial.
HIV :: Anal cytology predicts anal precancer in HIV-positive gay men
HIV-positive men who have sex with men are up to 90 times more likely than the general population to develop anal cancer. Detection of precancerous changes (anal dysplasia) by anal cytology ? essentially an anal canal Pap smear ? is a relatively new procedure and one that has yet to enter standard practice.
