Impact of Reconstructed Wetlands on the Tree Swallow (Tachycineta bicolor)
Tree swallow (Tachycineta bicolor) nestlings were used as a sentinel species to evaluate the bioavailability and effect of contaminants to terrestrial life at reconstructed wetlands, Kingman Lake and Kenilworth Marsh, on ...
Characterization of Glucocorticoid-Induced Changes in Gene Expression in the Embryonic Pituitary Gland
We have previously shown that corticosterone (CORT) can induce premature differentiation of somatotrophs in the chicken embryo. CORT induction of GH mRNA is indirect, in that protein synthesis inhibition blocks its inducing ...
Nutritional and Physiological Control of Metabolic Pathways That Alter Milk Protein and Lactose Synthesis by the Mammary Gland
The objectives of this research were to develop a [U-<sup>13</sup>C]glucose tracer approach establishing the pathways and substrates for milk lactose and casein synthesis, and determine the influence of protein ...
Regulation of macronutrient metabolism by the gastrointestinal tract of ruminants
We set out to test the hypothesis that the gastrointestinal tract (GIT) of ruminant animals catabolizes amino acids (AAs) preferentially. We sought to determine whether this catabolism represents an obligate requirement, ...
Effects of Moderate Calorie Restriction on Ovarian Function and Decline in Rhesus Monkeys
Calorie restriction (CR) has long been heralded as the only proven nutritional intervention for life extension. Recent data demonstrated that moderate CR also extended reproductive lifespan in female rats. The objectives ...
Estimation of Rumen Microbial Protein Production and Ruminal Protein Degradation
Animal agricultural production systems are a major source of nitrogen (N) which may contribute to potential environmental pollution and one way to reduce losses of N to the environment is through feeding protein closer to ...
