Chronic stress, prompted by major life stressors and type A personality traits, is linked to a high risk of stroke, finds research published online in the Journal of Neurology Neurosurgery and Psychiatry. Chronic stress, manifested as physical and/or mental symptoms in response to stressors lasting longer than 6 months has been linked to a heightened risk of heart disease. But its impact on the risk of stroke has not been clear.

Existing evidence suggests that patients with Alzheimer's disease who have taken Huperzine A have improved general cognitive function, global clinical status, functional performance and...

Older Men With Higher Testosterone Levels Lose Less Muscle Mass As...

A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that higher levels of testosterone were associated with reduced loss of lean muscle mass in older men, especially in those who were losing weight. In these men, higher testosterone levels were also associated with less loss of lower body strength.

Hope For Muscle Wasting Disease

A health supplement used by bodybuilders could be the key to treating a life-threatening muscular dystrophy affecting hundreds of Australian children, new research shows. The amino acid L-tyrosine had a "rapid and dramatic impact" on Nemaline Myopathy (NM) in laboratory tests on mice, significantly improving symptoms of the muscle wasting disease, medical researchers from the University of New South Wales (UNSW) found.

Statins: Benefits Questionable In Low-Risk Patients, Review Finds

There is not enough evidence to recommend the widespread use of statins in people with no previous history of heart disease, according to a new Cochrane Systematic Review. Researchers say statins should be prescribed with caution in those at low risk of cardiovascular disease (CVD).

Happiness Is ‘Infectious’ In Network Of Friends: Collective — Not Just...

If you're happy and you know it, thank your friends—and their friends. And while you're at it, their friends' friends. But if you're sad, hold the blame. Researchers from Harvard Medical School and the University of California, San Diego have found that "happiness" is not the result solely of a cloistered journey filled with individually tailored self-help techniques.

Circadian Rhythms Have Profound Influence On Metabolic Output

By analyzing the hundreds of metabolic products present in the liver, researchers with the UC Irvine Center for Epigenetics & Metabolism have discovered that circadian rhythms -- our own body clock -- greatly control the production of such key building blocks as amino acids, carbohydrates and lipids.

Signaling Path In Brain May Prevent That ‘I’m Full’ Message

Researchers at UT Southwestern Medical Center have identified a signaling pathway in the brain that's sufficient to induce cellular leptin resistance, a problem that decreases the body's ability to "hear" that it is full and should stop eating.

New Blood Test Could Detect Heart Disease In People With No...

A more sensitive version of a blood test typically used to confirm that someone is having a heart attack could indicate whether a seemingly healthy, middle-aged person has unrecognized heart disease and an increased risk of dying, UT Southwestern Medical Center researchers have found.

Researchers at the Cedars-Sinai Heart Institute have found in animals that infusing cardiac-derived stem cells with micro-size particles of iron and then using a magnet to guide those stem cells to the area of the heart damaged in a heart attack boosts the heart's retention of...
