Live Longer With Fewer Calories

By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process.

"We are able to show that caloric restriction slows down ageing by preventing an enzyme, peroxiredoxin, from being inactivated. This enzyme is also extremely important in counteracting damage to our genetic material," says Mikael Molin of the Department of Cell and Molecular Biology.

Higher Testosterone Levels Help To Protect Muscle Mass In Men As They Age

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.

Ophthalmologist Discovers Possible Side Effect In Macular Degeneration Drug

eye detailTwo major drug trials conclude there was little risk from a drug aimed at age-related macular degeneration. Yet a Mayo Clinic ophthalmologist began to note something concerning in some of her patients: an increase in pressure inside the eye. It led to a retrospective study and findings that will be presented at the American Academy of Ophthalmology in Orlando.

Sophie Bakri, M.D., had been treating patients in her clinic with Food and Drug Administration-approved ranibizumab (Lucentis), when she began noticing a change in some patients.
