1.Although osteoporosis is multifactorial, physical activity is important to the skeleton at any age because the associated weight-bearing and muscular activity stimulates bone formation and increases or at least stabilizes bone mass while immobilization leads to rapid bone loss.
2.STUDIES ON THE METABOLISM OF AMINO ACIDS IN THE SILK-WORMS:FORMATION OF THE CARBON SKELETON OF ALANINE FROM MALIC ACID IN BOMBYX MORI L.AND PHILOSAMIA CYNTHIA RICINI D.
3.The heat of formation (HOF) for a series of polynitroadamantanes was calculated systematically by using density functional theory (DFT) at B3LYP/6-31G * level by means of designed isodesmic reactions without breaking the adamantane skeleton ( i.e. choosing adamantane as a reference compound).
