Discovery alters long standing concept of fixed protein structure

The thousands of proteins found in nature are simply strings of amino acids, assembled by genes, and scientists have long believed that they automatically fold themselves into uniquely fixed, 3-dimensional shapes to fire the engine of life.

Blood vessel protein reverses macular degeneration, diabetic retinopathy in mice

Two major eye diseases and leading causes of blindness—age-related macular degeneration and diabetic retinopathy can be reversed or even prevented by drugs that activate a protein found in blood vessel cells, researchers at the University of Utah School of Medicine and several other institutions have announced in a new study.

First clinical trial data of a fully bioabsorbable drug-eluting stent

Data published today in The Lancet from ABSORB, the world's first clinical trial of a fully bioabsorbable drug eluting stent for the treatment of coronary artery disease, demonstrated no stent thrombosis, no clinically driven target lesion revascularizations (re-treatment of a diseased lesion), and a low (3.3 percent) rate of major adverse cardiac events (MACE) in 30 patients out to one year.

How diabetes drives atherosclerosis

Researchers have discovered how diabetes, by driving inflammation and slowing blood flow, dramatically accelerates atherosclerosis, according to research to be published in the March 14 edition of the journal Circulation Research. Experts once believed that atherosclerosis, or hardening of the arteries, developed when too much cholesterol clogged arteries with fatty deposits called plaques.

Study shows Parkinson's disease drug dopamine might work in cancer patients

A study published in the March 13 online issue of The Journal of Clinical Investigation shows that dopamine, a drug currently used to treat Parkinson's disease and other illnesses, also might work in cancer patients.

Personal counseling and web-based strategies show modest success for sustaining weight loss

Adults who lost weight in a six-month program were able to keep at least some of the weight off for 2.5 years with the help of brief monthly personal counseling, according to a new study from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. A Web-based intervention also helped participants keep the weight off for two years, but the benefit waned during the last six months of the trial

Post-stroke clot-busting therapy beneficial for patients on aspirin

Patients given a clot-busting drug following stroke appear to have better outcomes if they were already taking anti-platelet medications, despite an apparent increased risk for bleeding in the brain, according to an article posted online that will appear in the May 2008 print issue of Archives of Neurology.
