Small Protein, Big Impact: Microprotein Discovery Offers Hope for Obesity and Aging

Researchers have uncovered a tiny but powerful protein that helps keep our cells’ energy factories humming – a discovery that could spark new approaches to tackling obesity and age-related decline. Scientists at the Salk Institute in La Jolla found that a  “microprotein”  in mouse fat cells plays a critical role in maintaining healthy  mitochondria , the structures that generate energy in our cells. By preserving mitochondrial function, this diminutive protein helps cells burn fuel efficiently, which in turn could influence body weight and the aging process. The findings shine light on how molecular biology connects to everyday health, opening the door to  science-backed strategies for better metabolism and longevity.

Hormone Replacement Therapy, HRT: safe for healthy women entering menopause

Global menopause summit concludes HRT is safe for healthy women entering the menopause. HRT in the early postmenopausal period is safe, and healthy women going through the first few years of the menopause who need HRT to relieve symptoms should have no fears about its use. This is the conclusion and clinical advice of the First Global Summit on Menopause-Related Issues, which was held in Zürich on March 29th and 30th, 2008. The Zürich Summit was attended by global experts in menopause and related issues. It reviewed the evidence on the safety, risks and benefits of HRT in the first few years of the menopause, looking at 4 main areas of controversy: cardiovascular health, breast issues, cognition, and bone issues.

Summit members compared public perception with actual safety, and are now issuing a state-of-the science summary, to enable women and clinicians to make informed judgements about whether or not to use HRT in early menopause. Professor Amos Pines, President of the International Menopause Society, will present the Summit findings at the World Congress on the Menopause in Madrid on 20th May. via Eurekalert.
