Effective Stroke Drug Underused
A clot-dissolving drug called tissue plasminogen activator (tPA) is as effective in real-life settings as it has been in clinical trials, Canadian researchers report.
Blood Test for Ovarian Cancer Shows Promise

Alzheimer's Vaccine Research Back On Track
The idea of a vaccine against Alzheimer's disease may yet have some life left to it.
Gay Men Respond Differently to Pheromones
Gay men's brains respond differently from those of heterosexual males when exposed to a sexual stimulus, researchers have found. The homosexual men's brains responded more like those of women when the men sniffed a chemical from the male hormone testosterone.
Hawaii Faces Doctor Shortages
Hawaii faces doctor shortages in at least two fields — obstetrics and orthopedics — because fears of lawsuits and the rising cost of medical malpractice insurance premiums are forcing some to quit.
Center to Test Radio Wave Cancer Treatment
The University of Pittsburgh Medical Center is about to begin tests to find out whether heat from radio waves can be used to kill cancer cells without harming other cells and without negative side effects.
Low-Fat Dairy May Lower Risk of Diabetes
Eating low-fat dairy products may help slightly lower the risk of developing diabetes, a new study of more than 40,000 middle-aged men suggests.
Food Fact:
Plum role?
America has a prune glut, so help yourself -- and help your heart. Prunes, aka dried plums, are loaded with pectin, the soluble fiber that lowers blood cholesterol. They're also rich in iron and cancer-fighting antioxidants. As a health-conscious American, do your part by having a few prunes every day -- California orchardists, as well as your family doctor, will be glad you did.
Fitness Tip of the day:
Get in-line.
Step into a pair of skates for a head-turning pair of legs and a killer derriere. In-line skating is a strength-training and cardio workout all in one. Studies find in-line skating to be more aerobic than cycling, easier on your joints than running, and a great way to shape and tone muscles. Get rolling and you can burn 570 - 900 calories an hour!
FAQ of the day:
Is grape juice good for me?
White grape juice is mostly sugar and water, but purple grape juice, which includes the grape skins, is rich in the same heart-healthy compounds found in red wine. In a study at the University of Wisconsin Medical School, drinking a 12-oz. glass of purple grape juice a day reduced the tendency of blood clots to form by 40%. That's about the same as when people take aspirin to prevent heart attacks.
