Colostrum feeding and its effects on serum cortisol, thyroxine, immunoglobulin G and cytosolic glucocorticoid receptors in skeletal muscle in the bovine neonate
… calves, respectively. Cortisol levels between treatments were different (P<.05) at 2, 3, 12, 14, 18, 24, 37 and 48 h postpartum. The sex of the calf did not affect the mean cortisol concentrations. No treatment difference was observed for serum thyroxine. A sex difference was observed with the …

Power and Sample Size for Three-Level Cluster Designs
… Second, the variance structure of the estimated treatment difference is more complicated. Third, sample size results required for several levels are needed. In this work, we developed sample size and power formulas for the three-level data structures based on the generalized linear mixed model …

The impact of simulated motion blur on breast cancer detection performance in full field digital mammography (FFDM)
… analysis found a statistically significant difference in lesion detection performance for both masses (F (2,22) = 6.01, P=0.0084) and microcalcifications (F(2,49) = 23.14, P<0.0001). For both lesion types, the figure of merit reduced as the magnitude of simulated motion blur increased. …

Economic influences on and impacts of the migration of health professionals
… under the Scottish NHS in terms of retention and treatment provision. A discrete-time survival analysis has been applied to characterize the time trend of the retention and identify factors associated with the likelihood of a dentist leaving the NHS.

BLINDED EVALUATIONS OF EFFECT SIZES IN CLINICAL TRIALS: COMPARISONS BETWEEN BAYESIAN AND EM ANALYSES
… of a double-blind clinical trial that individual treatment allocation of patients remains unknown. Methods have been proposed for re-estimating the sample size of clinical trials, without unblinding treatment arms, for both categorical and continuous outcomes. Procedures that allow a blinded …

Holstein heifer behaviors and lactating cow nutritional management for improved reproductive performance on dairy farms
… heifers were randomly assigned to one of three treatments: control (CON), tail chalk; treatment-A (TRTA), tail chalk with proprietary ingredient; and treatment-B (SPRAY), spray formulation. Experimental design was a replicated 3x3 Latin square with 6 total squares, 3 animals per square, and 3 …

The Effect of Growth Hormone on Pig Embryo Development in Vitro and an Evaluation of Sperm-Mediated Gene Transfer in the Pig
… development was assessed on d 6 of culture. The treatment groups were as follows: treatment 1 = control group cultured in IVM medium alone; treatment 2 = 100 ng/ml pGH present of the first 22 h of maturation culture and absent for the second 22 h of maturation culture; treatment 3 = 100 ng/ml pGH …
