Pycnogenol significantly reduces muscular pain

A study published in this month's issue of Angiology shows that supplementation with the pine bark extract Pycnogenol. (pic-noj-en-all) improves blood flow to the muscles which speeds recovery after physical exercise.

COX enzymes work together in ways that suggest new biological roles

COX enzymes - well-known for their contrasting role in cardiovascular biology - interact physically to form a previously unrecognized biochemical partnership and function in the development of blood vessels in a mouse model.

Urgent effort underway to learn how diabetes increases heart disease risk

A researcher at the University of Rochester Medical Center has won the 2006 Thomas R. Lee Career Development Award from the American Diabetes Association (ADA), which includes an $842,400 grant to study how diabetes dramatically increases risk for cardiovascular disease.

Sildenafil improves blood flow after heart attack in an animal model

Dogs treated with sildenafil, a drug most commonly used to treat erectile dysfunction, had better blood flow in coronary arteries than control animals, following an induced artery obstruction and treatment that modeled a heart attack and standard medical care given to people

Study provides important insights into how different modes of training reduce muscle injury

If you're a mouse, then stretching before you exercise is a good thing - even as long as two weeks before your next cheese hunt or cat run. But if you're reading this for yourself, it's a bit more complicated.

Proteomics yields new drug targets for treating cardiogenic shock

When it comes to cell signaling and bioregulation, it's tough to find a more important molecule than nitric oxide (NO). Dysfunction of NO-mediated signaling is thought to be a culprit in lethal cardiovascular conditions such as angina, and septic, cardiogenic and hemorrhagic shock; it may play a role in many other illnesses as well.

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.

Details of protein-cleaving complex key to microbe's survival may improve drug design

With the hope of designing more effective treatments for tuberculosis (TB), scientists from the U.S. Department of Energy's Brookhaven National Laboratory and collaborating institutions have published the first detailed reports on the biochemistry and structure of a protein-cleaving complex that is essential to the TB bacterium's survival.

Why people of African descent are more vulnerable to tuberculosis infection

A team of scientists has identified a cellular mechanism that may help explain the puzzle of why people of African descent are more susceptible to tuberculosis infection and why, once infected, they develop more severe states of the disease than whites.

University of Florida researchers restore vitality to cells in lab experiments

University of Florida researchers say primitive cells that act like molecular maintenance men - traveling throughout the body to repair damaged blood vessels - become too rigid to move in patients with diabetes, fueling the disease's vascular complications.
