Blood Vessels

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.

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.

First-baseman Greg Walker of the Chicago White Sox, who suffered a seizure during batting practice July 30, was released from the hospital and is expected to return to action in 10 to 15 days. Doctors determined that Walker's problem was caused by an inflammation of blood vessels in the brain.

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.

Scientists said Thursday that they have isolated a gene that instructs the body to build tiny new blood vessels, a crucial step in cancer growth, and they say this could open new strategies to defeat malignancies. The researchers who purified and analyzed the protein, named angiogenin, which this gene controls, say it is the first time that an organ-forming protein has been understood in detail. The discovery is the culmination of 10 years of work by Dr. Bert L.
Scientists are harnessing light beams to fight one of the most insidious problems of aging, providing a ray of hope against a creeping blindness that steals vision from the center out. Age-related macular degeneration, or AMD, is the leading cause of blindness in people over 50. First, fine detail fades. Your crossword puzzle seems OK at a glance, until you try focusing on just one word. People's faces start to blur. You can't read or drive. Eventually, the worst form of AMD causes blindness.

Eating vegetables with your meat may take the edge off the damage the fat can do, at least in the short run. An Italian study of healthy young men and women found that adding tomatoes, carrots and peppers, which are good sources of antioxidants, to a high-fat meal lessened its negative effect on the cells lining the blood vessels.
