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.

Why is it that some people lose weight and body fat when they exercise and eat less and others don't? German researchers say MRI and magnetic resonance (MR) spectroscopy can provide the answer -- and help predict who will benefit from lifestyle changes. Results of the study are published online and will appear in the November issue of the journal Radiology.

Stress has numerous detrimental effects on the human body. Many of these effects are acutely felt by the sufferer, but many more go 'unseen', one of which is shortening of telomere length. Telomeres are protective caps on the ends of chromosomes and are indicators of aging, as they naturally shorten over time. However, telomeres are also highly susceptible to stress and depression, both of which have repeatedly been linked with premature telomere shortening.

You might think that the DNA you inherited is one thing that you absolutely can't do anything about, but in one sense you'd be wrong. Researchers reporting in the March issue of Cell Metabolism, a Cell Press publication, have found that when healthy but inactive men and women exercise for a matter of minutes, it produces a rather immediate change to their DNA.

UC Davis scientists have uncovered a key suspect in the destructive inflammation that underlies heart disease and diabetes. The new research shows elevated levels of a receptor present on leucocytes of the innate immune response in people at risk for these chronic diseases. The receptors are the body's first line of defense against infectious invaders, and they trigger a rush of cytokines, the body's aggressive immune soldiers, into the bloodstream.

University of Minnesota Medical School researchers have collaborated with the School of Public Health and discovered an enzyme that, when found at high levels and alongside low levels of HDL (good cholesterol), can dramatically reduce the risk of cardiovascular disease.

Metabolic syndrome comprises a group of medical disorders that increase people's risk of diabetes, heart disease, stroke, and premature death when they occur together. A patient is diagnosed with the syndrome when he or she exhibits three or more of the following characteristics: high blood pressure, high blood sugar, excess body fat in the waist/abdomen, low good cholesterol, and higher levels of fatty acids (the building blocks of fat).

Older individuals' complaints about memory lapses such as having trouble remembering recent events may indicate that they are experiencing cognitive problems that are greater than typical age-related changes. These findings, which are published September 15 in the Journal of the American Geriatrics Society, indicate that...

People who wolf down their food are two and a half times more likely to suffer from type 2 diabetes than those who take their time according to new research presented at the joint International Congress of Endocrinology and European Congress of Endocrinology in Florence, Italy.

A large study found strong evidence that older people who have age-related macular degeneration (AMD) are at increased risk for coronary heart disease (CHD), although not for stroke. This result adds to mounting evidence that AMD and cardiovascular disease may share some risk factors–smoking, high blood pressure, inflammatory indicators such as...

Middle-age men and women who have cardiovascular issues, such as high cholesterol and high blood pressure, may not only be at risk for heart disease, but for an increased risk of developing early cognitive and memory problems as well. That's according to a study released Feb. 21 that will be presented at the American Academy of Neurology's 63rd Annual Meeting in Honolulu April 9 to April 16, 2011.

Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have published an article in Science revealing that the COX-2 inflammation enzyme stimulates the formation of new brown fat tissue in mice. Brown fat tissue transforms energy into heat. Therefore..
