Byproduct of cholesterol metabolism blocks heart health benefits of estrogen

New findings by UT Southwestern Medical Center researchers show that a byproduct of cholesterol metabolism interferes with the beneficial effects estrogen has on the cardiovascular system, providing a better understanding of the interplay between cholesterol and estrogen in heart disease.

Byproduct of cholesterol interferes with the beneficial effects of estrogen on the heart

A new study possibly offers a biological reason why hormone replacement therapy (HRT) fails to protect some postmenopausal women from heart disease.

Exercising in bad air could be a killer

A new study by British and Swedish researchers has found that air pollution could potentially harm the blood vessels and clotting abilities of people with heart disease.

Platelets help white blood cells fight inflammation

Scientists have shown for the first time that platelets, the cells needed for blood clotting, help white blood cells called neutrophils fight inflammation.

Scientists isolate stem cells in womb tissue

Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors.

New understanding of tropical disease schistosomiasis

Researchers have provided new details about the inner workings of a parasitic worm that causes a tropical disease called schistosomiasis, which leads to itchy skin, fever, chills, muscle aches, and liver disease that, in some cases, can be fatal.

Novel angiogenic drugs could revolutionize treatment of peripheral arterial disease

Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that the market entry of novel angiogenic agents, including a future blockbuster drug from Genzyme, could revolutionize symptomatic treatment of peripheral arterial disease (PAD).

Link between nicotine and atherosclerosis

It's well known that smoking cigarettes increases risk for a host of serious health problems from cancer to heart disease. Now a new study from Weill Cornell Medical College in New York City looks at how they do their dirty work by contributing to atherosclerosis, or hardening of the arteries. The evidence points to nicotine, the addictive chemical in cigarettes.

Micro-needles a safe alternative to hypodermic syringes

New research presented at the British Pharmaceutical Conference (BPC) in Manchester shows that micro-needles may be a safer and less painful method for delivering vaccines and other medicines traditionally administered using a hypodermic syringe.

Tendons found to contain a small subset of previously unknown adult stem cells

Tendon, the cord-like tissue that connects muscle to bone, contains a small subset of previously unknown adult stem cells, scientists at the National Institute of Dental and Craniofacial Research (NIDCR) part of the National Institutes of Health, and their colleagues have discovered.

Scientists identify process that causes blood vessels to constrict during and after a heart attack

They've also demonstrated that delivering a vital molecule that is depleted during this process directly to those blood vessels can reverse damage and help restore blood flow.

Vitamin C inhibits the growth of some tumors

Nearly 30 years after Nobel laureate Linus Pauling famously and controversially suggested that vitamin C supplements can prevent cancer, a team of Johns Hopkins scientists have shown that in mice at least, vitamin C - and potentially other antioxidants - can indeed inhibit the growth of some tumors ¯ just not in the manner suggested by years of investigation.

Brain does most of the work in seeing the difference between colours, rather than the eye

Colour contrast is detected much earlier in the brain than previously thought, a new study shows. Scientists at Durham University have confirmed that colour contrast is first detected by part of the brain called primary visual cortex, which is located at the very back of the head where visual information first enters the cortex of the brain.

Radiation and drug combo helps boost efficacy of lung-cancer treatment

Combining radiation therapy with a drug that helps destroy blood vessels nourishing malignant tumors has been shown in mice to be significantly more effective in treating lung cancer than either approach alone, researchers at UT Southwestern Medical Center have found.

Myoendothelial cells identified as new human source of stem cells with potential to repair muscle

For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy.

Smoking and Alzheimer's disease

People who smoke are more likely to develop Alzheimer's disease or dementia than nonsmokers or those who smoked in the past, according to a study published in the September 4, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.
