The role of altered glucose metabolism in the growth retardation associated with the Fetal Alcohol Syndrome has been difficult to assess because previously used experimental procedures have frequently substituted ethanol for dietary carbohy...
Glucocorticoid hormone adversely affects the growth and regeneration of cartilage in vitro [0.03%]

In most field studies on growth rates of birds, chicks are weighed in the "morning" or whenever it is convenient. I found that weight of laboratory-reared young herring gulls (Larus argentatus) varied significantly depending on the time of ...
The effect of low level prenatal X-irradiation on postnatal growth in the Wistar rat [0.03%]

Forty-five pregnant Wistar strain rats were exposed to 0.0, 0.4, 0.6, or 0.8 Gy X-radiation on the 9th or 17th day of gestation to determine if prenatal X-irradiation would result in alterations in postnatal growth or growth rate. The mothe...

Estimation of body composition by measurement of tetrapolar bioelectrical resistive impedance (R) is a technique only recently validated in adults. To evaluate this technique in children, 16 girls aged 11.6 +/- 0.9 yr (mean +/- SD) and 14 b...
Asymptotic growth and complex allometry of the brain and body in the white rat [0.03%]

A new four-parameter version of Pütter's growth curve (Pütter, 1920) is obtained by replacing time by a smooth non-negative function which incorporates an initial delay. Fitted through constrained iteratively-reweighted multiplicative lea...
Allomorphic relationships from hatching to 56 days in parental lines and F1 crosses of chickens selected 27 generations for high or low body weight [0.03%]
