Postmenopausal women may be at higher risk of having a stroke than they think. A new study by researchers at NYU Langone Medical Center and colleagues found that traditional risk factors for stroke -- such as high cholesterol -- are not as accurate at predicting risk in postmenopausal women as previously thought.

Adults who take one of the world's most commonly prescribed sleep medications are significantly more at risk for nighttime falls and potential injury, according to a new study by the University of Colorado at Boulder.

A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests that hyperglycemia (high blood sugar) injures the heart, even in patients without a history of heart disease or diabetes. Researchers found that elevated levels of glycated hemoglobin (HbA1c), a marker for chronic hyperglycemia and diabetes, were associated with minute levels of the protein troponin T (cTnT), a blood marker for heart damage.

For many patients, cholesterol-lowering statin drugs can reduce the risk of strokes as well as heart attacks. But in a review article, Loyola University Health System neurologists caution that statins may not be appropriate for cetain categories of patients who are at risk for stroke.

Taking arginine supplements can improve the cycling ability of over-50s. Researchers writing in BioMed Central's Journal of the International Society of Sports Nutrition tested a combination of the amino acid and an antioxidant in sixteen cyclists, finding that it enhanced their anaerobic threshold...

Researchers at Karolinska Institutet have shown in a new study on mice, that cell therapy can be used to reverse the effect of 'bad' LDL cholesterol and reduce the inflammation that leads to atherosclerosis. The new cell therapy, which is presented in the scientific journal Circulation, can open the way for new therapies for stroke and myocardial infarction if the results prove translatable to humans.

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.

Li et al. explain how prolonged stress sparks the endoplasmic reticulum (ER) to release its calcium stores, inducing cells to undergo apoptosis in several aging-related diseases. The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14). Stressful conditions cause misfolded proteins to accumulate in the ER. Cells try to recover by slowing down...

Women who take some types of bone-building drugs used to prevent and treat osteoporosis may be at lower risk of breast cancer, according to a study by U.S. researchers published in the British Journal of Cancer.

A daytime sleep could have cardiovascular benefits according to new research by Ryan Brindle and Sarah Conklin, PhD, from Allegheny College in Pennsylvania in the US. Their study, looking at the effect of a daytime nap on cardiovascular recovery following a stress test, found that those participants who slept for at least 45 minutes during the day had lower average blood pressure after psychological stress than those who did not sleep.

The discovery by UCLA biochemists of a new method for preventing oxidation in the essential fatty acids of cell membranes could lead to a new class of more effective nutritional supplements and potentially help combat neurodegenerative disorders such as Parkinson's disease and perhaps Alzheimer's.

Agricultural Research Service (ARS)-funded scientists have reported new reasons for choosing "heart-healthy" oats at the grocery store. Nutritionist Mohsen Meydani, director of the Vascular Biology Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at...
