Opis

This book presents biochemical, nutritional, and metabolic implications related to sarcopenia. It provides information on mechanisms regulating age-related loss of muscle mass and function as well as nutritional anti-aging strategies to fight against atrophy and support healthy aging.

O autorze

Dominique Meynial-Denis studied Biochemistry and Molecular Biology at the University Paul Sabatier of Toulouse, France and obtained her Ph.D. degree on intermolecular interactions between drug and plasma proteins followed by magnetic resonance spectroscopy (MRS) at the same University in 1985. Since 1986, she has worked as a scientist at the National Institute of Agricultural Research (INRA) in Clermont-Ferrand in a Department focussing on Human Nutrition. Consequently, she became a Nutritionist and specialised her research on Sarcopenia and Aging in 1994. She applied MRS to metabolic pathways of amino acids in muscle during aging. Dominique Meynial-Denis received a second Ph.D. in 1998 on amino acid fluxes throughout skeletal muscle during aging. More recently, she has mainly been interested in the effect of glutamine supplementation in advanced age. She is a member of the French Society of Enteral and Parenteral Nutrition (SFNEP), of the European Society of Clinical Nutrition and Metabolism (ESPEN), of the Société Française de Nutrition (SFN), of the International Association of Gerontology and Geriatrics (IAGG) and of the Société Francophone de Gérontologie et Gériatrie (SFGG). She is a regular referee to different international journals on Nutrition as well as Aging.
