In order to integrate proliferation and differentiation patterns during kidney development, precise ontogenic profiles of several morphometric and biochemical parameters were determined in the mouse. During early nephron formation (before t...
Growth allometry of organs, muscles and bones in mice from lines divergently selected on the basis of plasma insulin-like growth factor-I [0.03%]

R A Siddiqui et al.
Growth allometry was examined over the range 6 to 112 days of age in male and female mice from lines selected for low (L) or high (H) plasma concentrations of insulin-like growth factor-I (IGF-I). Plasma IGF-I concentrations were greater in...

A method is proposed for the comparison of morphological parameters that compensates for sex and age effects. An index is calculated for individual animals, from which percentage differences in size that are independent of age-sex classes c...
Morphometric studies in inbred and hybrid house mice. VIII. Effects of litter size on brain size and body size [0.03%]

Litter size, brain size, and body size were examined in inbred and hybrid house mice of three different ages in order to test whether litter size exhibits a positive genetic, but negative environmental association with both brain and body s...

Metamorphic vertebrate species are of particular interest in ecological and evolutionary studies because the decoupling of larval and adult growth patterns potentially allows adaptive diversifications of the separate stages. Larval and adul...

Simulations of nestling growth in Great Tits (Parus major) were used to show the consequences genetic variation in the parameters of growth curves could have on the amount of genetic variation in final body weight. This was done for the cas...
Survival and reproduction in Peromyscus leucopus in the laboratory: viable model for aging studies [0.03%]
J Burger,M Gochfeld
J Burger
White-footed mice Peromyscus leucopus reared in our laboratory from wild-caught parents lived at least to 5.5 years. Once past weaning, over 80% of the mice lived at least until two years. Females maintained a constant weight whereas the we...
Morphometrical analysis of the short-term effects of hypophysectomy and food restriction on skeletal muscle fibers in relation to growth and aging changes in the rat [0.03%]
垂体切除与食物限制对幼年及成年大鼠肌纤维短期影响的形态计量学分析及其生长与老化变化的关系研究

Muscle fiber growth is impaired by lack of hormonal influence. In the case of the gastrocnemius muscle of the male Wistar rat, ablation of the pituitary at age 60 days results in cessation of the growth of type 1 muscle fibers, and a reduct...
Growth and utilization of nutrients in newly-hatched chick with or without removal of residual yolk [0.03%]
是否去除蛋黄残渣对雏鸡生长及养分利用的影响

Two experiments were conducted to characterize the growth and utilization of nutrients in newly-hatched chicks, and to determine nutritional roles of residual yolk by comparing chicks with or without deutectomy (removal of residual yolk sac...
