A 32-nucleotide deletion (delta 32) within the beta-chemokine receptor 5 (CCR5) gene has been described in subjects who remain uninfected despite extensive exposure to HIV-1. This allele was found to be common in the Caucasian population with a frequency of 0.0808, but was not found in people of African or Asian ancestry. To determine its role in HIV-1(More)
Dried distillers grains produced from a mix of 65% barley and 35% corn were evaluated in digestion and lactation experiments. Dried barley distillers grains had 56% NDF, 29% CP, 3% amino acid N, 2.5% NDIN (55% of total N), and 1.8% ADIN (39% of total N). Wet barley distillers grains had 38% NDF, 27% CP, 2.7% amino acid N, .5% NDIN (12% of total N), and .8%(More)
The role of protein kinase C in ornithine decarboxylase (ODC; EC 4.1.1.17) gene expression in primary culture of newborn mouse epidermal cells (MEC) from BALB/c mice and in skin tumor promotion by 12-O-tetradecanoylphorbol-13-acetate (TPA) in female CD-1 mice was determined. A time course and the dose-response curves of ODC induction paralleled that of ODC(More)
Evidence was sought that the tumour promoter 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced mouse epidermal ornithine decarboxylase (ODC, EC 4.1.1.17) activity involves both increased ODC mRNA and ODC protein. Application of 10 nmol of TPA to mouse skin led to a dramatic increase in soluble epidermal ODC activity which paralleled an increase in amount(More)
Ten ruminally and duodenally cannulated (326 +/- 28 kg) and four esophageally fistulated (394 +/- 23 kg) steers grazing cool-season pasture throughout the growing season were used to evaluate the influence of Aspergillus oryzae fermentation extract (AO) supplementation on intake, forage nutrient utilization, and duodenal amino acid flow. Steers grazed a(More)
Four nonlactating Holstein cows (593 kg) with ruminal cannulas were fed bromegrass hay that was fertilized with 0 or 89 kg of N/ha and harvested in the late-boot or full-head stage of maturity. Total tract apparent digestibility of N was less for full-head than for late-boot bromegrass (48 vs 64%; P less than .01) and was greater for N-fertilized than for(More)
Four rumen-cannulated, mature crossbred wethers were used in a 4 x 4 latin square experiment designed to examine the effects on protein metabolism of protein sources with various solubilities fed with low quality roughages. Four diets were used: (1) grass hay plus oat straw (control), (2) control plus urea, (3) control plus soybean oil meal (SBOM) and (4)(More)
