Three experiments were conducted to determine the effects of n-methyl-D,L-aspartate (NMA), an agonist of the excitatory amino acid glutamate, on secretion of hormones in boars. In Exp. 1, boars (185.0+/-.3 d of age; mean +/- SE) received i.v. injections of either 0, 1.25, 2.5, 5, or 10 mg of NMA/kg BW. There were no effects of NMA (P>.1) on secretion of LH and testosterone. Treatment with NMA, ...

This study was performed to evaluate the efficiency of four different lineages (95/01, L1, 96/22 and JABK) of Lentinula edodes (BERK.) Pegler mushroom (shiitake) for inhibiting the N-ethyl-N-nitrosourea (ENU) clastogenicity in vivo. Male Swiss mice (10 animals/group) were treated during 15 consecutive days with dried mushroom added to basal diet under three different concentrations (1, 5 and 10...

the effect of nanoparticle diamond incorporated in an experimental dental adhesive formulation is valuated by examining the mechanical properties and shear bond strength of the system. diamond nanoparticles were incorporated into the dentin adhesive system in different concentrations of 0, 0.05, 0.1, 0.2, 0.5, and 1.0 weight percentages. the suspensions were ultrasonicated to facilitate the nan...

Serum and pituitary growth hormone (GH) concentrations were measured by radioimmunoassay in 69 Duroc and 70 Yorkshire swine genetically selected for at least 14 generations for either high backfat (high line) or low backfat (low line). For both breeds, the high line pigs had lower serum GH at weaning (P<.05) and lower serum and pitui tary GH at slaughter (P<.01) than the unselected control line...

s / Journal of Equine Veterinary Science 34 (2014) 76 76 x106sperm/mL. Sperm recovery rate after centrifugation was lower in low concentration samples (p<0.001). Mean lactate concentration at T0 was the same in all three groups and directly correlated with raw semen volume (r1⁄40.5032; p1⁄40.0103). Lactate concentrations at T0 and T24 were not correlated. Compared to T0, lactate concentration w...

A 2 x 3 factorial experiment conducted in three replicates of a randomized complete block design compared the effects of calcium selenite and sodium selenite at three different levels of Se (.3, 5, or 15 ppm) in the diets of growing swine on performance and tissue Se concentrations. Ninety pigs averaging 12.5 kg of BW were given ad libitum access to corn-soybean meal diets fortified with one of...

7-hydroxystaurosporine (UCN-01) infused for 72 hours by continuous i.v. infusion induced insulin resistance during phase I clinical trials. To understand the mechanism for this observation, we examined the effect of UCN-01 on insulin-stimulated glucose transport activity with 3-O-methylglucose in isolated rat adipose cells. UCN-01 inhibits glucose transport activity in a dose-dependent manner a...

The objective of the present study was to compare whole pea flour (WPF) to fractionated pea flour (FPF; hulls only) for their ability to reduce risk factors associated with CVD and diabetes in overweight hypercholesterolaemic individuals. Using a cross-over design, twenty-three hypercholesterolaemic overweight men and women received two-treatment muffins/d containing WPF, FPF or white wheat flo...
