Eighteen wether lambs, surgically equipped with abomasal and ileal cannulae, were used in two metabolism trials. Two levels of dietary Mg (.1 and .2%) and three levels of K (.6, 2.4 and 4.8%, dry basis) were fed with a 2 x 3 factorial arrangement. Each trial consisted of a 10-d preliminary period, a 7-d collection of feed, feces and urine for determining mineral balance and a 6-d sampling of fe...

The vapor phase fluorescence spectra of p-benzoquinone-84 and & are reported and discussed in relation to the assignment of the low lying singlet states. The low temperature, polarized single crystal electronic absorption spectra of p-benzoquinone and several of its isotopic derivatives are reported. From the isotope shifts and band polarizations of the various vibronic origins, a detailed vibr...

It is normally expected that an excellent optical material should have p → s-like transitions at the absorption edge. This is because the strength of p → s-like transitions usually is much stronger than those of p → p transitions, especially in those ionic semiconductors where the electronic states are more localized and behave as atomic characters. Here, we demonstrate an exception that the lu...

In proton-nucleus and nucleus-nucleus collisions up to central S −U interactions, the P T-dependence of J/ψ production is determined by initial state parton scattering and pre-resonance nuclear absorption (" normal " J/ψ suppression). The " anomalous " J/ψ suppression in P b−P b collisions must reduce the normal P T broadening, since it occurs mainly in the central part of the interaction regio...

Two experiments were conducted to investigate the effect of Mn source on Mn absorption by the intestine of broilers. In Experiment 1, the effect of Mn source, including MnSO(4), 2 Mn-amino acid chelates (Mn-Gly and Mn-Met) synthesized in our laboratory, 3 Mn-amino acid complexes with different complex strengths (Mn-Met E, Mn-AA A, and Mn-AA B), and 2 mixtures of MnSO(4) with Gly or Met, on Mn a...

Iron deficiency is common, especially among young women. Adding probiotics to foods could be one way to increase iron absorption. The aim of this study was to test the hypothesis that non-haem iron absorption from a fruit drink is improved by adding Lactobacillus plantarum 299v (Lp299v). Iron absorption was studied in healthy women of reproductive age using a single-blind cross-over design in t...

background although the immunosuppressant cyclosporine (csa) is widely used after kidney transplantation over the long term, there is still no firm consensus on the best way to monitor of csa blood levels. objectives cyclosporine (csa) assay is critical for the management of renal transplant recipients due to inter– and intra–patient variation in csa absorption and metabolism. patients and meth...

Studies were conducted to determine the effects of lysocellin and monensin on mineral metabolism of steers fed forage-based diets. In each study treatments consisted of 1) control, 2) 100 mg lysocellin/d, 3) 200 mg lysocellin/d and 4) 200 mg monensin/d. Twenty-four growing Hereford steers were used in each of two experiments to evaluate the effects of ionophore feeding on plasma and ruminal sol...

Meat increases absorption of non-haem iron in single-meal studies. The aim of the present study was to investigate, over a 5 d period, the potential increasing effect of consumption of pork meat in a whole diet on the fractional absorption of non-haem iron and the total absorption of iron, when compared to a vegetarian diet. A randomised cross-over design with 3 x 5 d whole-diet periods with di...
