How the treatment of common thyroid disease reduces tiredness and the risk factors for heart disease

Putting on weight and feeling lethargic?

Then new research from Newcastle University and funded by Gateshead NHS Foundation Trust shows it is worth having your thyroid levels checked – as these can be symptoms of thyroid disease which is easily identified and treated.

Obesity May Be Associated With A Relative Of Anti-aging Gene, Klotho

A relative of the anti-aging gene Klotho helps activate a hormone that can lower blood glucose levels in fat cells of mice, making it a novel target for developing drugs to treat human obesity and diabetes, UT Southwestern Medical Center researchers have found.

Dr. Makoto Kuro-o, associate professor of pathology, has reported that a relative of the anti-aging gene Klotho helps activate a hormone that can lower blood glucose levels in fat cells of mice. This discovery of a particular type of Klotho protein could eventually make it a novel target for developing drugs to treat human obesity and diabetes.

Discovery in plants suggests entirely new approach to treating human cancers

For the first time, scientists from the University of Washington School of Medicine, Indiana University Bloomington and the University of Cambridge have determined how a plant hormone — auxin — interacts with its hormone receptor, called TIR1. Their report, on the cover of this week’s issue of Nature, also may have important implications for the treatment of human disease, because TIR1 is similar to human enzymes that are known to be involved in cancer.

Afternoon naps may boost heart health

The next health trend might come out of nursery school instead of the gym: A study of nearly 24,000 people found that those who regularly took midday naps were nearly 40% less likely to die from heart disease than non-nappers.

Researchers suggest that siestas might protect the heart by lowering levels of stress hormones.

No Longevity Benefit with Growth Hormone

Surveyors of anti-aging elixirs tout human growth hormone as a remedy for all things sagging-from skin to libidos – and claim it can even prevent or reverse aging. But researchers at the Stanford University School of Medicine say there’s no evidence to suggest that this purported fountain of youth has any more effect than a trickle of tap water when it comes to fending off Father Time.

Popular anti-aging supplement has no beneficial effects, study finds

A widely used antiaging supplement has no effect on aging markers such as muscle strength, peak endurance, muscle mass, fat mass and glucose tolerance in elderly men and women, according to Mayo Clinic researchers. The findings from their two-year study appear in the Oct. 19 issue of the New England Journal of Medicine.

The findings serve to dispel the belief that dehydroepiandrosterone (DHEA), sold extensively as an antiaging supplement in health and grocery stores, can reverse age-related alterations in body composition and function, says the study’s lead author K. Sreekumaran Nair, M.D., Mayo Clinic endocrinologist.

Elevated testosterone kills nerve cells

-A Yale School of Medicine study shows for the first time that a high level of testosterone, such as that caused by the use of steroids to increase muscle mass or for replacement therapy, can lead to a catastrophic loss of brain cells.

Taking large doses of androgens, or steroids, is known to cause hyperexcitability, a highly aggressive nature, and suicidal tendencies. These behavioral changes could be evidence of alterations in neuronal function caused by the steroids, said the senior author, Barbara Ehrlich, professor of pharmacology and physiology.
