Staying active may lower health risks for large, retired athletes

The larger body size of professional football players doesn't increase risk of cardiovascular disease or atherosclerosis after they retire, according to research presented at the American Heart Association's Scientific Sessions 2008.

Scientists map steps to block enzyme phosphodiesterase 5's action in heart failure

Taking a cue from the way drugs like Viagra put the biological brakes on a key enzyme involved in heart failure, scientists at Johns Hopkins have mapped out a key chemical step involved in blocking the enzyme.

Dental pulp stem cells show promise for use in cell therapy

Researchers at the Yerkes National Primate Research Center, Emory University, have discovered dental pulp stem cells can stimulate growth and generation of several types of neural cells.

Compound found that blocks SARS virus

A Purdue University researcher has created a compound that prevents replication of the virus that causes SARS and could lead to a treatment for the disease.

Newborn neurons in the adult brain can settle in the wrong neighborhood

A new study published in this week's PLoS Biology could have significant consequences for neural tissue transplantation to treat brain injuries or neural degeneration.

Neck arteries of obese children and teens look more like those of 45-year-olds

Researchers used ultrasound to measure the thickness of the inner walls of the neck (carotid) arteries that supply blood to the brain. Increasing carotid artery intima-media thickness (CIMT) indicates the fatty buildup of plaque within arteries feeding the heart muscle and the brain, which can lead to heart attack or stroke.

Nanomatrix stent coating designed to mimic natural endothelium

A nanomatrix for stent coating designed at the University of Alabama at Birmingham (UAB) mimics natural endothelium, the substance that lines blood vessels, and promises the potential to prevent post-operative tissue scaring along the blood vessel wall, greatly reducing the possibility of future thrombosis, or blockage at the stent site.

Do statins cause muscle problems?

A Michigan State University researcher is studying whether the most popular class of cholesterol-lowering drugs may cause muscle problems in users.

New development of optical probes in chemistry

A chance discovery by a team of scientists using optical probes means that changes in cells in the human body could now be seen in a completely different light.

Ultrasound used to improve prediction of heart attacks

By adding the results of an imaging technique to the traditional risk factors for coronary heart disease, doctors at Baylor College of Medicine in Houston found they were able to improve prediction of heart attacks in people previously considered low risk.

Joyful music has a healthy effect on blood vessel function

Listening to your favorite music may be good for your cardiovascular system.

Catheter ablation works better than drugs for heart rhythm disorder

Treating a common heart rhythm disorder by burning heart tissue with a catheter works dramatically better than drug treatments, a major international study has found.

Genetics for personalized coronary heart disease treatment

Identifying a single, common variation in a person's genetic information improves prediction of his or her risk of a heart attack or other heart disease events and thus, choice of the best treatment accordingly, said researchers at Baylor College of Medicine in Houston.

Sex hormones may affect atherosclerosis

Naturally produced sex hormones may influence the risk and progression of atherosclerosis, or hardening of the arteries, Johns Hopkins researchers report in a recent study.

Damage inflicted by cholesterol crystals during cardiac attacks more widespread

Cholesterol crystals released in the bloodstream during a cardiac attack or stroke can damage artery linings much further away from the site of the attack, leaving survivors at greater risk than previously thought.

Taking calcium and vitamin D supplements does not reduce breast cancer risk

Taking calcium and vitamin D supplements does not reduce breast cancer incidence in postmenopausal women, according to data from a randomized, doubled-blind, placebo-controlled trial published online November 11 in the Journal of the National Cancer Institute.

Neuroprosthetic brain implants may help stroke patients overcome partial paralysis

Scientists have shown for the first time that neuroprosthetic brain implants may be able to help stroke patients with partial paralysis.

New study highlights potential for cost effective NHS policy

A new University of Leicester study reveals that screening people who are at risk of developing diabetes could be a cost-effective health policy and improve the lives of patients.

Medicine, math and engineering combine to reveal how sepsis and less severe infections occur

It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.

Large trial on low-dose aspirin in diabetics

Type 2 diabetics treated with low-dose aspirin did not have a significantly lower incidence of atherosclerotic events than those who received placebo in this primary prevention trial of low-dose aspirin, according to research presented at the American Heart Association's Scientific Sessions 2008. However, sub-group analyses showed a significant reduction with aspirin in both atherosclerotic events in those over 65 years of age, and a reduction in cerebrocardiovascular deaths.
