The in vitro scavenging effects of MPP and MPP-4b at a dosage of 10 g/L on hydroxyl radical were 94.15 +/- 8.27% and 96.61 +/- 8.06%, respectively. The 1,1-diphenyl-2-picrylhydrazyl inhibition percentages of two polysaccharides fractions were 93.37 +/- 7.66% and 70.79 +/- 6.15%, respectively. The reducing power (absorbance at 700 nm) of MPP and MPP-4b were 4.31 +/- 0.26 and 5.09 +/- 0.33, respectively. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“In the present
work, the click here effect of Dy3+ substitution on the structural and magnetic properties of CoFe(2-x)DyxO(4) (x = 0.00 to 0.1 in step of 0.025) system synthesized by solution combustion method were investigated. The thermal decomposition process was investigated by means of differential and thermal gravimetric analysis that showed that the precursor could yield the final product after calcination above 600 degrees C. The phase purity and crystal lattice symmetry were estimated from X-ray diffraction studies. The microstructural features were observed by scanning electron microscopy selleck chemicals that demonstrates the fine clustered particles with an increase of average grain size with Dy3+ content. The existence of constituent’s, i.e., Co,
Fe, and Dy were authenticated by energy dispersive X-ray analysis. An infrared spectroscopy study shows the presence of two absorption bands in the frequency range around 590 cm(-1) (nu(1)) and around 480 cm(-1) (nu(2)); which indicate the presence of tetrahedral and octahedral group complexes, respectively, within the spinel lattice. Room temperature magnetization measurements showed that the saturation magnetization and hysteresis losses (coercivity) decreases with Dy3+ addition, which implies
that these materials may be applicable selleck products for magnetic data storage and recording media. (C) 2011 American Institute of Physics. [doi:10.1063/1.3632987]“
“In this study, the influence of the probiotics, Pediococcus acidilactici (PA) and Saccharomyces cerevisiae boulardii (SCB), on intestinal immune traits and resistance to enterotoxigenic Escherichia coli (ETEC) infection was evaluated in pigs. Two weeks before farrowing, 30 sows and their future litters were allocated to the following treatments: 1) control group without antibiotic or probiotic treatment (CTRL), 2) control with antibiotic (tiamulin) added to weanling feed (ABT), or litters treated with 3) PA, 4) SCB, or 5) PA+SCB from 24 h after birth. During lactation, PA, SCB, or PA+SCB were given to piglets 3 times a week by gavage. After weaning at 21 d of age, probiotics or ABT were added to the diet. Four pigs per litter were chosen to evaluate performance and blood concentrations of folic acid and vitamin B(12). Three of these were orally challenged with an ETEC strain on d 49 to 51 and killed on d 52. Three piglets from the rest of the litter were slaughtered on d 18 and 3 others on d 24.
