Minuscule amounts of ethanol, the type of alcohol found in alcoholic beverages, can more than double the life span of a tiny worm known as Caenorhabditis elegans, which is used frequently as a model in aging studies, UCLA biochemists report. The scientists said they find their discovery difficult to explain.

“This finding floored us — it’s shocking,” said Steven Clarke, a UCLA professor of chemistry and biochemistry and the senior author of the study, published Jan. 18 in the online journal PLoS ONE, a publication of the Public Library of Science. (more…)

MU Researchers Find Unique Protein Organization in Arteries Associated with Cardiovascular Disease

*Knowledge could assist in tissue replacements, treatments for high blood pressure and diabetes*

COLUMBIA, Mo. – Human arteries – some smaller than a strand of hair – stiffen as a person ages. This stiffening is a factor in cardiovascular disease, the leading cause of death in the United States, because it contributes to the circulatory complications in disorders such as high blood pressure and diabetes. University of Missouri researchers have now used advanced 3-D microscopic imaging technology to identify and monitor the proteins involved in this stiffening process. These findings could eventually help researchers and physicians understand and treat complications associated with cardiovascular disease. (more…)

Tai Chi Helps Prevent Falls and Improves Mental Health in Elderly

Tai Chi helps reduce the risk of falls in the elderly, and improves mental health, is what a new study shows. However, practicing the ancient Chinese art does not help to ease the symptoms of cancer or rheumatoid arthritis.

The information is from the research of a team that analyzed 35 reviews of studies evaluating the effects of Tai Chi on health.

The databases reviewed were British, Chinese and Korean that assessed the impact of Tai Chi on various diseases, including diabetes, hypertension, cancer, osteoarthritis, Parkinson’s, musculoskeletal pain, rheumatoid arthritis, osteoporosis and cardiovascular disease. (more…)

Couples-oriented Programs Found to Boost Healthy Behaviors Among African Americans

Intervention programs that promote healthier eating, increased physical activity and cancer screenings may be beneficial for African American couples that are at high risk for chronic diseases and that include one partner who is HIV-positive, according to new research.

With such inverventions, each partner appears to draw encouragement from the other to monitor his or her own lifestyle and health, according to study co-author Gail Wyatt, a professor of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience and Human Behavior at UCLA and an associate director of the UCLA AIDS Institute.

A Dose of Safflower Oil Each Day Might Help Keep Heart Disease at Bay

COLUMBUS, Ohio – A daily dose of safflower oil, a common cooking oil, for 16 weeks can improve such health measures as good cholesterol, blood sugar, insulin sensitivity and inflammation in obese postmenopausal women who have Type 2 diabetes, according to new research.

This finding comes about 18 months after the same researchers discovered that safflower oil reduced abdominal fat and increased muscle tissue in this group of women after 16 weeks of daily supplementation.

This combination of health measures that are improved by the safflower oil is associated with metabolic syndrome, a cluster of symptoms that can increase risk for cardiovascular disease and diabetes. (more…)

Stroke Takes ‘Enormous Toll’ on Hollywood Stars

A study by researchers at the UCLA Stroke Center found that stroke and cardiovascular disease have exacted an enormous toll on Hollywood stars.

The findings were presented at the American Heart Association/American Stroke Association’s International Stroke Conference (ISC) in Los Angeles on Feb. 10.

“Since this is the first time the ISC is being held in Los Angeles, we thought it was an appropriate occasion to investigate the frequency and impact of stroke among leading Hollywood actors,” said Hannah Smith, a staff research associate at the UCLA Stroke Center. “By documenting the toll that stroke and myocardial infarction have exacted on stars like Kirk Douglas and Grace Kelly, we hope to illustrate the damage that cardiovascular disease can cause.” (more…)

Why Coffee Protects Against Diabetes

*Researchers discover molecular mechanism behind drink’s prophylactic effect*

Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.

Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body’s sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG. (more…)
