California researchers have developed a technique to grow artificial blood vessels from a patient's own skin cells -- a technique that could quickly find application in kidney-failure victims undergoing dialysis. The technique has been tested in 10 patients, and preliminary results published Thursday in the journal Lancet suggest that the blood vessels can remain viable for long periods. "This technology is very, very promising," Dr.

Dr. Judah Folkman, the Harvard surgeon who parlayed a chance observation into a bold and controversial new way to fight cancer and a host of other diseases, has died. He was 74. Folkman was changing planes at the Denver airport on his way to a conference in Vancouver, Canada, when he died Monday of a heart attack, his family said.

washington -- Edward M. Kennedy, the senior Democratic senator from Massachusetts, underwent surgery Friday to clear a partially blocked artery in his neck. Kennedy, 75, had the hourlong procedure at Boston's Massachusetts General Hospital, where surgeons removed a blockage from his left carotid artery, which supplies blood to the head and neck. Kennedy's doctors called the operation "routine" and "uneventful."

"House," Feb. 6, 9 p.m., "Needle in a Haystack." The premise: A 16-year-old is brought to the hospital after experiencing breathing difficulties while making out with his girlfriend. When a chest X-ray reveals fluid in the pleural space (lining of the lung), Dr. Gregory House and his team conclude that the fluid must be blood, so they shoot dye into the teen's veins (venogram) and then his arteries (arteriogram) searching for the source.

An arteriovenous malformation, or AVM, like that suffered by Sen. Tim Johnson (D-S.D.), is like the four-level interchange writ large -- a complicated, tangled mass of blood vessels that connect arteries to veins. Present at birth, the tangles lie hidden and symptom-less in the brain for decades. But eventually, the constant pressure produced when the muscular arteries pump blood directly into the weaker, more fragile veins, causes the veins to spring small leaks.

The increasingly common practice of preventing strokes by using wire mesh stents to prop open neck arteries is much riskier than the traditional method of surgically removing plaque and should be curtailed, according to two large European studies. Patients receiving the stents were nearly 2 1/2 times as likely to have a stroke or die, French researchers reported today in the New England Journal of Medicine.

Answering the "decaf or regular" question has become more problematic. Caffeine can give some people the jitters, keeping them awake or speeding up their heart rate, but decaffeinated coffee, researchers have found, may be bad for your heart. Java without the jolt increases the levels of so-called bad cholesterol in the bloodstream and reduces levels of good cholesterol, researchers reported last week at a meeting of the American Heart Assn. in Dallas.

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.

According to the Bible, "A merry heart doeth good like a medicine." Now, modern science may be validating that Old Testament proverb -- a good laugh may actually help fend off heart attacks and strokes. "We believe laughing is good for your health," said Michael Miller, of the University of Maryland School of Medicine in Baltimore, who led the research. "And we think we have evidence to show why that's the case."

Once considered a disease of middle age and later years, high blood pressure actually has its roots in early childhood. Those roots are now present in an increasing number of children and teens. "What we're finding is that with the current epidemic of overweight and couch-potato children, a higher percentage than ever before are in the hypertensive range," said Dr. Julie R. Ingelfinger, a pediatrics professor at Harvard Medical School.
