background: &beta-glucans; are glucose polymers with a variety of stimulatory effects on the immune system. the objective of this study was to evaluate the immune-enhancing activities of low molecular weight gamma irradiated &beta-glucan; (i&beta-g;) extracted from pleurotus ostreatus in response to pseudomonas aeruginosa infection in rats. materials and methods: &beta-glucan; (&beta-g;) powder...

We hypothesize that investors partially think about stock price changes in dollar rather than percentage units, leading to more extreme return responses news for lower-priced stocks. Consistent with such non-proportional thinking, we find a doubling is associated 20% 30% decline volatility and beta (controlling size/liquidity). To identify causal effect, show jumps following splits drops revers...

A novel beta-glycosidase-producing microorganism was isolated from soil and identified as Aspergillus fumigatus AP-20 based on its taxonomical characteristics. The enzyme was found to be an extracellular protein in the culture of the isolated fungus and was purified 88-fold by fractionation with ammonium sulfate followed by successive column chromatographies on phenyl-Sepharose HP and Mono P HR...

An on-line coupled capillary isotachophoresis-capillary zone electrophoresis (cITP-CZE) method for the determination of the fumaric acid content in apple juice is presented. A clear separation of fumaric acid in real samples is achieved within 20 min. The leading, terminating and background electrolyte of the employed system consist of 10 mM HCl+beta-alanine+5 mM beta-cyclodextrin+0.05% hydroxy...

Serum samples from 72 patients with established carcinoma of the breast were investigated for ectopic presence of hPL. Further, the relationship of ectopically-secreted hPL and hCG-beta in breast cancer was investigated. Ten of 72 patients examined had detectable hPL and 12 had detectable hCG-beta, at 1-2 ng/ml serum sensitivity of the assay. The presence of hPL in serum of breast cancer patien...
