Australian researchers find key 'go-betweeen' in heart disease

Medical researchers at the University of New South Wales (UNSW) - Australia, have shed light on a little-known mechanism involved in the thickening of arteries, a process associated with heart disease.

New method to increase the efficiency of contrast radiology

A new method to increase the efficiency of contrast radiology may open the way to earlier and more reliable diagnosis of, for example, breast cancer. With new integrated electronics and signal processing, the image quality can be improved sharply.

Mental stress induced ischemia more common than thought

Even when heart disease patients can pass stress tests done on a treadmill or with chemical stressors after treatment, their hearts may still suffer silent ischemia during mental stress, according to a new study in the Mar. 7, 2006, issue of the Journal of the American College of Cardiology.

Using a growth factor to stimulate production of circulating endothelial progenitor cells improves cell production and mobility in arterial disease

Using a growth factor to stimulate production of circulating endothelial progenitor cells increases the numbers of these vascular regenerative cells, improves mobility, and potentially could improve blood vessel function in patients with peripheral arterial disease (PAD).

Nebivolol may restore damaged cardiovascular functions in African Americans

Tadeusz Malinski, Marvin & Ann Dilley White Professor of Chemistry and Biochemistry, found that the drug, currently under review by the U.S. Food and Drug Administration, acts on the level of oxidants lining the cardiovascular system and can restore levels of nitric oxide and reduce oxidative stress.

How close Americans live to hospitals that can perform angioplasty

University of Michigan and Yale analysis shows that within 60 minutes, 80 percent of Americans could reach a hospital that can do emergency angioplasty.

Cornell develops technique for making living, functional cells glow

The development gives researchers insights into how hearts develop in living mouse embryos and could improve our understanding of irregular heartbeats, known as arrhythmias, as well as open doors to observing cellular processes to better understand basic physiology and disease.

Exposure to fine particle air pollution significantly increases the risk for cardiovascular and respiratory disease

New data from a four-year study of 11.5 million Medicare enrollees show that short-term exposure to fine particle air pollution from such sources as motor vehicle exhaust and power plant emissions significantly increases the risk for cardiovascular and respiratory disease among people over 65 years of age.

Coffee good or bad for you? It depends on your genes!

Scientists know that coffee, a major source of caffeine, is metabolized by the enzyme, cytochrome P450 1A2, and some individuals who have that particular gene are "rapid" caffeine metabolizers, whereas those with a different variation of the gene are "slow" caffeine metabolizers.

Study may lead to ways to reduce heart attacks in diabetes patients

For people with type 2 diabetes, the death rate from a first heart attack is two to three times the death rate of patients without the disease. Similarly, patients with diabetes and ischemic (reduced blood flow) heart disease have a much higher mortality rate than the general population.

Catheter ablation for chronic atrial fibrillation improves quality of life

People who have endured the effects and risks of an irregular heartbeat for years can get long-lasting relief from a procedure that takes less than two hours, a definitive new study shows.

Gene therapy approach used in creating new arteries for older patients does not appear to cause cancer

"This result is an encouraging step along the road to new tissues for patients to replace those that have failed or have been destroyed due to trauma or disease," she said.

Space suit technology can protect workers from heatstroke

The technology used in space suits to protect astronauts carrying out space walks in direct sunlight is now being used to develop protective clothing to safeguard firefighters and steel workers who often work in extremely hot and dangerous conditions.

Individualized treatment options for rosacea

Many individuals who are struggling with redness, pimples and visible blood vessels on their face may incorrectly diagnose their condition as acne, sunburn or sensitive skin.

Fibulins inhibit both tumor growth and blood-vessel formation

Researchers at National Jewish Medical and Research Center report in the March issue of Cancer Research that a pair of promising proteins, known as fibulins 3 and 5, slow the growth of cancer tumors in mice by preventing blood vessels from sprouting. The proteins are promising candidates for use in cancer therapy.

Bone marrow stem cells do not improve cardiac function in heart attack patients

There has been increasing evidence that stem cells contribute to regeneration of cardiac tissue and the development of new blood vessels following a heart attack, thus opening up new prospects for stem-cell based therapies.

New method for examining how radiation damages body tissue

The knowledge may make it possible to reduce side effects for cancer patients or to develop treatments for radiation exposure.

Hydrogel scaffold materials used to create stable networks of blood vessels

Yale biomedical engineers have created an implantable system that can form and stabilize a functional network of fine blood vessels critical for supporting tissues in the body, according to a report in the Proceedings of the National Academy of Sciences.
