W J Koops
Diphasic functions were applied to growth curves for body weight and for tail length of mice that were progeny of a transgenic male mated to random-bred NMRI females. A group of 20 female and male mice with high (H) body weight at week 12, ...
Separation of two subpopulations of old human fibroblasts by mitochondria (rhodamine 123) fluorescence [0.03%]
线粒体荧光（若丹明123）分离老年人成纤维细胞的两个亚群
A O Martinez,D Over,L S Armstrong et al.
A O Martinez et al.
The mitochondria-binding fluorescent dye rhodamine 123 (R123) was used to sort two subpopulations of cells from mass cultures of old human fibroblasts (HF). Both subpopulations showed unusual dye retention kinetics when compared to young HF...
Reduction in rate of occurrence of age related lesions in dietary restricted laboratory mice [0.03%]

In young adults rats (5-month-old) d-amphetamine (2 mg/kg/d), administered on a long-term basis via drinking water, caused a moderate reduction in the intake of nutriments, which in part normalized within three weeks. Self-administration of...
Growth retardation during the suckling period in expanded litters of rats: observations of growth patterns and protein turnover [0.03%]
大鼠扩群哺乳期间的生长迟缓：生长模式和蛋白质周转观察
J D Johnson,W J Wogenrich,K C Hsi et al.
J D Johnson et al.
Postnatal patterns of growth and protein turnover were studied in suckling rats derived from expanded (EL) as compared to contracted (control) suckling rats (Widdowson and McCance, 1960). Maximum deviation of body weight growth velocity in ...

Melatonin increases serum growth hormone and insulin-like growth factor I (IGF-I) levels in male Syrian hamsters via hypothalamic neurotransmitters [0.03%]
褪黑素通过下丘脑神经递质增加雄性叙利亚仓鼠的血清生长激素和胰岛素样生长因子-I(Igf-i)水平
J Vriend,M S Sheppard,K T Borer

In male Syrian hamsters daily evening melatonin injections resulted in increased circulating levels of growth hormone (GH), as well as a modest increase in body weight. A substantial increase in serum levels of insulin-like growth factor I ...
The effect of clenbuterol administration in utero and throughout lactation on pre- and post-natal muscle development in the rat [0.03%]

The beta-adrenergic agonist, clenbuterol was fed to pregnant rats during gestation and throughout lactation. Changes in muscle morphology and composition were studied in foetal and weanling rats. Drug treatment did not affect mean foetal nu...
Reduced mature size in progeny of swine severely restricted in protein intake during pregnancy [0.03%]
妊娠期蛋白质摄取量受限的母猪所产生的后代成熟度下降
W G Pond,J T Yen,H J Mersmann et al.
W G Pond et al.
The objective was to determine the effects of maternal gestation diet on mature body and organ size and composition of progeny. Female progeny of swine fed daily 1.8 kg (6,000 kcal DE) of a semipurified diet containing less than 0.5% protei...
Emerging fractal properties in gorgonian growth forms (Cnidaria: Octocorallia) [0.03%]
石珊瑚科枝珊瑚属生物的分形性质及生长方式研究
B Burlando,R Cattaneo-Vietti,R Parodi et al.
B Burlando et al.
Gorgonian growth has been hitherto studied mostly by investigating the influence of different environmental conditions on shape and orientation. We have made an attempt at analyzing the intrinsic growth properties of these organisms, by usi...
Growth hormone secretion in the obese male rat: modulation by the gonadal and thyroid axes [0.03%]
肥胖大鼠生长激素的分泌：下丘脑垂体性腺轴和甲状腺轴的调节作用
W J Millard,T M Romano,M P Layden et al.
W J Millard et al.
The present study was designed to determine if either the testes or thyroid plays a role in the blunted GH secretion observed in the obese male rat. Analysis of individual GH secretory profiles in adult lean and obese Zucker rats revealed a...
