New research gives the first solid evidence that a type of fat in the bloodstream can trigger the earliest steps that lead to clogged blood vessels, researchers said Wednesday. If further research bears this out, people might someday be tested for this fat, just as they are for cholesterol now, to see if they're in danger of having a heart attack. The study found that levels of the fat strongly correlated with the risk of heart disease, especially in people under 60.

Ever found a mysterious black-and-blue mark on your body and wondered how it gotthere? Whether the result of major trauma or an inadvertent bump, bruising is one way to assess damage to tissue. The factors involved in what makes a bruise and how it heals are fairly simple. In an effort to get to the bottom of bruising, we went to three specialists who deal in bruises: Dr. Philomena McAndrew, a Los Angeles hematologist; Dr. William Shankwiler, a Pasadena orthopedic surgeon, and Dr.

British actress Judi Dench is seeking to downplay fears over the revelation that she is suffering from a degenerative eye condition. The Oscar-winning Dench, perhaps best known as James Bond's mysterious boss M, has been dealing with two different forms of macular generation -- one in each eye. According to Reuters, she can no longer read scripts and has to have someone read them out loud to her, "like reading me a story. " According to the National Eye Institute, macular degeneration occurs in an area known as the macula, which sits at the center of the light-sensitive tissue known as the retina, located at the back of the eye socket.

Lucentis, known generically as ranibizumab, is the only drug approved by the Food and Drug Administration for treating the wet form of age-related macular degeneration, commonly known as AMD. But Lucentis costs as much as $2,000 per dose, so many physicians have begun substituting the similar anti-cancer drug Avastin (bevacizumab), which costs less than $150 per dose. Some studies have indicated that Avastin is just as effective as Lucentis, and many public agencies in the United States and Canada have begun authorizing its use in an effort to save money, although such use has not been approved by the FDA or its Canadian equivalent.

Step away from the beer pong table! College binge drinking may leave you with more than just embarrassing memories and excruciating hangovers. In a study published Tuesday in the Journal of the American College of Cardiology , researchers found that four years of heavy drinking between the ages of 18 and 25 may be enough to permanently increase a person's risk of heart attack, stroke and atherosclerosis. Researchers at the University of Illinois recruited 38 nonsmoking young adults and split them into two groups: alcohol abstainers and binge drinkers.

In her youth, my sister (who is not exactly a delicate flower) would sometimes faint. It was never quite clear why, and the episodes eventually passed. I was impressed. I couldn't even faint when I tried, and I did try once, in my teens. A pal devised a kind of "fainting recipe" that involved antics like rapid inhaling and exhaling. The antics didn't work.

The discovery that an enzyme called thrombin has two different ways to tell blood platelets to form a clot might help researchers develop new therapies for clotting disorders like heart attacks and strokes, researchers from UC San Francisco report in today's issue of the journal Nature. When blood vessels are injured or the flesh is cut, thrombin activates platelets--the little cells that clump together to plug blood vessels.

Scientists Thursday reported progress in cutting off blood supply to a wide variety of tumors in laboratory animals, a finding that could lead to new ways of making human cancers shrink and disappear. "We don't want to oversell this--we're not saying we have the magic bullet, there's a lot more research to be done. But so far, we have green lights," said Dr. David A. Cheresh, one of the lead scientists on the project at the Scripps Research Institute in La Jolla.
