Future blood tests may use tiny bar-codes to speed disease diagnosis
Analyzing a blood sample for the presence of disease markers, either in a doctor's office or on the battlefield, could soon become as quick and easy as scanning the bar-code of a grocery item. Using nanotechnology, researchers at Northwestern University have developed a way to label tiny disease markers in blood with unique DNA tags, which they call bio-bar-codes. The tags can then be scanned by an instrument to identify diseases ranging from cancer to Alzheimer's, or identify exposure to bioterror agents such as anthrax and smallpox, they say.  more

Questions and answers on exocrine pancreatic insufficiency drug products
PEPs aid in the digestion of meals in patients who have diseases affecting their pancreatic function.

These enzymes break down fats (lipase), proteins (protease) and complex carbohydrates (amylase) to allow absorption of these nutrients into the body. more

HIV patients get long-term boost with short, intermittent drug regimen
National Institutes of Health (NIH) scientists report that brief, widely-spaced courses of the experimental immune-boosting drug interleukin-2 (IL-2) allow people with HIV to maintain near normal levels of a key immune system cell for long periods. The researchers, from NIH's National Institute of Allergy and Infectious Diseases (NIAID) and the Warren G.
