Juvenile BALB/c mice were used as a model system to test the effects of various loading and exercise regimens on the growth and development of femora. Six treatments and three controls were used to document changes in geometric, mechanical,...
Effect of dietary fat and aging on adipose tissue cellularity in mice differing in genetic predisposition to obesity [0.03%]
膳食脂肪和衰老对具有不同肥胖遗传易感性的小鼠脂肪组织细胞的影响

M S Edwards et al.
A line of mice had been developed which became obese when fed a commercial mouse breeder chow. This obese line was compared to a non-obese line at various ages to determine whether the type or amount of dietary fat would affect adipocyte si...
Body and muscle growth of domestic turkeys (Meleagris gallopavo) and expression of myosin heavy chain isoforms in breast muscle [0.03%]
