Zapped Arteries Remain Largely Clean And Clear Six Months Postangioplasty, Per BERT-1 Results
Coronary arteries remain open six months after mild irradiation in 90 percent of postangioplasty patients evaluated inthe Beta Radiation for Restenosis Trial (BERT-1), reports Emory University at the 70th American Heart Association 70th Scientific Sessions.

Anti-Clotting Drug Used During Angioplasty Reduces Need For Subsequent Bypass Surgery
An analysis of data from three multi-center trials has shown that 19 percent fewer angioplasty patients required coronary artery bypass graft surgery within six months if they received a monoclonal antibody drug just prior to the procedure, Duke University Medical Center researchers reported Monday.

New Yale Study Demystifies Cognitive Centers Of The Brain
Scientists at Yale University School of Medicine used physiological techniques to map the prefrontal cortex of primates as they were shown visual stimuli.

Scientists Close To Finding Gene That Controls Growth Of Lung Cancer
In what may move scientists a step closer to locating a gene that helps control the growth of lung cancer, researchers at Duke University Medical Center have found in a new study that fragments of a portion of a human chromosome slow tumor growth in mice and in cell cultures.

Carnegie Mellon, Pitt Brain Imaging Researchers Receive Grants To Study Reasoning And Decision-Making
Carnegie Mellon University and University of Pittsburgh researchers have received nearly $16 million to collaborate on a first-ever research effort that will use brain imaging to analyze complex human thought processes--how people make plans, make decisions under time pressure or solve problems.

Exercise Improves Heart Function In Elderly People With Heart Failure
Older people with chronic congestive heart failure can significantly improve their functional independence by exercising moderately three times a week, according to a study led by Johns Hopkins physicians.

Direct Evidence Of A Receptor For 'Good' Cholesterol To Be Reported By MIT Team
In work that could lead to new treatments for atherosclerosis, the leading cause of death in Western industrialized countries, MIT biologists have nailed down the function of a key protein involved in cells' uptake of the so-called

Chemists Create A Molecular Antenna That Harvests Light
Scientists at the University of Michigan and the University of Illinois at Urbana-Champaign have developed a new class of large, organic molecules which could one day be used for focusing and converting sunlight into electricity.

Researchers Say Good Cholesterol Can Turn Bad
Long considered the

Do Doctors Say No To High-Dollar Requests?
A woman with fatigue worries that she has multiple sclerosis, but her history and physical examination make MS very unlikely.

Observations Support New Model Of Sun's Magnetic Field
Evidence is mounting that the sun's magnetic field looks more like a wild cyclone than a tidy lawn sprinkler---the image scientists had accepted for almost 40 years.

VUMC Researchers Report BRCA1 Clinical Trial Results.
The first gene therapy clinical trial using the BRCA1

Strokes Associated With Heart Surgery Exact High Costs
One in five people who has a stroke associated with heart surgery dies before leaving the hospital and only one in four is able to return straight home after hospitalization for their surgery, according to a study by Johns Hopkins physicians.

Study Reversal: Direct Angioplasty Isn't Better Than Clot-Busting Drugs For Treating Heart Attacks
Contradicting earlier research, a Duke University Medical Center study of patients from 57 hospitals indicates that treating a heart attack by unclogging it with a balloon catheter fails in the long run to save substantially more people than therapy with clot-busting drugs.

7-Year-Olds' Neurological Development Shows Delays From Methylmercury In Mothers' Diets During Pregnancy
Extensive tests of 917 seven-year-old children in the Faroe Islands have shown statistical relationships between some of the results of a battery of neurological tests and the extent of maternal methylmercury exposure among mothers who frequently consumed whale meat, as well as other seafood, during pregnancy.

Test Identifies Children At Risk For Life-Threatening Rapid Heart Rhythm
A simple, widely available test may help identify young children at risk of developing life-threatening rapid heartbeats, report researchers today at the American Heart Association's 70th Scientific Sessions.

Protein Released By Dying Heart Muscle During Heart Attacks Identifies High-Risk Patients, Predicts Long-Term Risk
Two different multi-hospital studies have demonstrated that a blood test can indicate which heart attack patients may be in danger of dying from a heart attack, Duke University Medical Center researchers reported Monday.

Cholesterol Levels Remain High Despite Education, Medications
Cholesterol levels remain high above recommended levels despite widespread education efforts and wider availability of cholesterol-lowering drugs, a physician from the University of Rochester reported today at the annual meeting of the American Heart Association in Orlando.

Exercise May Fatally Rupture Artery Plaque Of Sedentary Men With Heart Disease And High Cholesterol
For people with heart disease and high blood levels of cholesterol, heavy exertion -- even mowing the lawn -- may trigger a sudden heart attack by rupturing the plaque obstructing the arteries of the heart, according to a study presented today at the American Heart Association's 70th Scientific Sessions.

Researchers Seek Replacement For Road Salt
Within the next 5 years, residents of the Great Lakes region may see their dedendence on road salt decrease, along with a decrease in landfill wastes.

UB Study Maps How Brain Monitors Multiple Conversations
Neuroscientists at the University at Buffalo have produced an image of how your brain musters its neuronal resources as you try to monitor two simultaneous conversations.

U-M Scientists Date Origin Of Moon In Earth's "Big Bang"
U-M geochemists have made the most accurate estimate yet of the age of our moon and discovered that it formed later in the development of the solar system than many scientists believed---almost certainly as the result of a collision between Earth and another planet at least as large as Mars.
