From each calf, blood samples were collected before
and approximately 24 hours after treatment. Serum IgG and total protein (TP) concentrations were quantified with standard methods, and the apparent efficiency of IgG absorption was calculated.
Results-At 24 hours after treatment, mean serum TP and IgG concentrations were significantly lower for calves fed pooled MC (TP, 4.77 g/dL; IgG, 750 g/L), compared with those for calves fed the LDCR (TP, 5.50 g/dL; IgG, 15.15 g/L). Calves fed the LDCR were 95% less likely to develop FPT (OR, 0.05; 95% confidence interval, 0.03 to 0.08) than were calves fed pooled MC. However, buy LCL161 the mean IgG concentration in the pooled MC fed during the study (21.1 g/L) was substantially lower than that (64.3 g/L) determined for representative samples of pooled MC from other southwestern
US dairies during a national survey.
Conclusions and Clinical Relevance-Results indicated that, on this particular dairy, calves fed an LDCR were at less Y-27632 datasheet risk of developing FPT than were calves fed pooled MC. The LDCR evaluated was a viable alternative for the prevention of FPT in calves.”
“in this study, in order to isolate inulinase overproducers from the marine yeast Pichia guilliermondii, its cells were treated by using UV light and LiCl. The mutant M-30 with enhanced inulinase production was obtained and was found to be stable after cultivation for 20 generations. Response surface methodology (RSM) was used to optimize the medium compositions and cultivation conditions for inulinase production by the mutant M-30 in liquid fermentation. Inulin, yeast extract, NaCl, temperature, pH for maximum inulinase production by the mutant M-30
were found to be 20.0g/l. 5.0 g/l. 20.0 g/l. 28 degrees C P-gp inhibitor and 6.5, respectively. Under the optimized conditions, 127.7 U/ml of inulinase activity was reached in the liquid culture of the mutant M-30 whereas the predicted maximum inulinase activity of 129.8 U/ml was derived from RSM regression. Under the same conditions, its parent strain only produced 48.1 U/ml of inulinase activity. This is the highest inulinase activity produced by the yeast strains reported so far. We also found that inulin could be actively converted into monosaccharides by the crude inulinase. (C) 2008 Elsevier B.V. All rights reserved.”
“High-performance liquid chromatography coupled with an ultraviolet detector was used to quantitatively determine the amount of caffeoylquinic acid, arctium lappa glycoside, aurantiamarin and forsythin present in five solvent extracts (water, 30% ethanol, 50% ethanol, 70% ethanol and 95% ethanol) of Yinqiaosan (YQS). The calibration curves of the four components were linear (r(2)>0.998) over the concentration range of 0.9-151.5 mu g/mL. This method showed good repeatability with relative standard deviations of less than 2.9% and mean recoveries of 91.3-100.5%. We established the relative amounts of each of the four main ingredients in YQS for all five solvent extracts.
