The objective of this study was to examine the effect of anabolic steroids (testosterone, T; dihydrotestosterone, D; trenbolone acetate, B; and zeranol, Z) on cortisol synthesis by cultured bovine adrenocortical cells. Adrenal glands were obtained from slaughter-aged steers (n = 4). Cortical cells were isolated and their steroidogenic capacity was examined. They were plated in multiwell culture...

Our objective was to evaluate the effects of substituting feather meal (FM) for soybean meal (SBM) on ruminal fiber fermentation, lamb gain, blood metabolite profiles, and wool growth. A SBM supplement was formulated, and FM replaced either 33% (33FM), 66% (66FM), or 100% (FMS) of the SBM protein. Four ruminally cannulated wethers were used in a 4 x 4 Latin square design to study in situ rumina...

OBJECTIVE We sought to evaluate the pharmacokinetics of subcutaneously administered enoxaparin sodium during and after pregnancy. STUDY DESIGN Daily subcutaneous injections of enoxaparin sodium (40 mg) were administered to 13 pregnant women. On 3 separate occasions, once early in pregnancy (12-15 weeks), once late in pregnancy (30-33 weeks), and once in the nonpregnant state (6-8 weeks post p...

Treatment of lambs (initial BW 28 kg) for 24 d with a combined implant containing 40 mg of trenbolone acetate (TBA) and 8 mg of estradiol (E2) increased ADG 25% ( P < .05, n = 8) and feed efficiency 23% ( P < .05, n = 2) compared with unimplanted lambs. By d 3 following implantation, sera from wethers implanted with TBA + E2 showed 32% (307 vs 233 ng/mL) increases ( P < .001, n = 8) in IGF-I co...

PURPOSE Available tumor markers have low sensitivity/specificity for the diagnosis of liver tumors. The present study was designed to evaluate the oxidoreductive status of the liver as surrogates of tumor subsistence and growth. METHODS Glutathione species (GSH:GSSG), ophthalmate (OA) concentrations, and their turnover were measured in plasma of rabbits (n = 6) in their healthy state and in t...

BACKGROUND AND PURPOSE Elevated levels of plasma fibrinogen are a risk factor for cerebral infarction. Because fibrinogen plays a central role in platelet aggregation and binding of fibrinogen to platelets is inhibited by ticlopidine, we studied the effect of the plasma fibrinogen concentration on the antiaggregatory action of ticlopidine compared with that of aspirin. METHODS We determined p...

The effect of soybean meal, feather meal and hair meal on dry matter (DM), energy and nitrogen (N) utilization by growing steers was evaluated in three metabolism studies. Feather meal (FM) and hair meal (HM) protein were substituted for 25, 50 and 75% (Exp. 1, 2 and 3, respectively) of the soybean meal (SBM) protein in pelleted protein supplements and fed in whole-shelled, corn-ground corncob ...

PURPOSE Peak power (PP) and mean power (MP) attained in upper body sprint performance test are considered important factors for competitive success in wrestling. This study aimed to determine whether acute caffeine ingestion would better maintain PP and MP across a simulated competition day in wrestling. METHODS In a double-blind, counterbalanced, crossover study, 14 trained wrestlers ingeste...

OBJECTIVES/HYPOTHESIS To perform a subset analysis of faith- and community-based screening events to further identify at-risk populations for head and neck cancer in hopes of further focusing screening efforts. STUDY DESIGN Prospective cohort study. METHODS Three hundred fifty-three individuals (n=353) presented to community events and self-selected for head and neck cancer screenings. A su...

Sixty steer calves of mixed British breeding averaging 268 kg were randomly assigned to four treatment groups of 15 calves each to determine the influence of pre-fast dietary roughage content on recovery from feed and water deprivation. Three groups were fed diets containing either 84 (HR), 60 (MR) or 35% (LR) roughage at 1.75% of body weight for 3 d. Calves in these three groups were deprived ...
