Objective(s) The fractions of Candida albicans have been used as an immunomodulator. The present work assessed the effect of different fractions of C. albicans on nitric oxide (NO) production by mice peritoneal macrophages. Materials and Methods Cell wall and cytoplasmic fractions of C. albicans ATCC 10321 strain were extracted. Mice peritoneal macrophages were purified and cultured. Differen...

an experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (se) sources on broiler male birds (ross 308). uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental se, negative control), 0.25 ppm of inorganic se, 0.5 ppm of inorganic se, 0.25 ppm of inorganic se + 0.25 ppm of organic ...

The size distribution of aerosol particles (PM0.015-PM18) in relation to their soluble inorganic species and total water soluble organic compounds (WSOC) was investigated at an urban site of Thessaloniki, Northern Greece. The sampling period was from February to July 2007. The determined compounds were compared with mass concentrations of the PM fractions for nano (N: 0.015 < Dp < 0.06), ultraf...

This study was conducted to determine the effects of organic and inorganic chromium (Cr) supplementation on performance parameters, eggshell quality and some serum parameters of laying Pharaoh quails (Coturnix coturnix Pharaoh). Laying quails (n: 360; 59 days old) were randomly divided into three experimental groups each including 120 birds. Basal diet applied to control group was based on corn...

Inorganic pyrophosphate promoted the acidification of an intracellular compartment in permeabilized procyclic trypomastigotes of Trypanosoma brucei, as measured by acridine orange uptake. The proton gradient generated by pyrophosphate was collapsed by addition of nigericin or NH(4)Cl. Pyrophosphate-driven proton translocation was stimulated by potassium ions and inhibited by KF, by the pyrophos...

Inorganic arsenic is a strong carcinogen, possibly by interaction with the telomere length. The aim of the study was to evaluate how chronic arsenic exposure from drinking water as well as the arsenic metabolism efficiency affect the individual telomere length and the expression of telomere-related genes. Two hundred two women with a wide range in exposure to arsenic via drinking water (3.5-200...

Burge, W. D. (University of California, Berkeley), E. Malavolta, and C. C. Delwiche. Phosphorylation by extracts of Nitrosomonas europaea. J. Bacteriol. 85:106-110. 1963.-Cellfree preparations of Nitrosomonas europaea are capable of oxidizing hydroxylamine, but not ammonium ion, to nitrite. The quantity of nitrite formed by our preparations was, at most, equivalent to only 70% of the hydroxylam...

Water treatment residues (WTR), the by-products of the production of potable water, are chemically benign, inorganic materials which are suitable for disposal by land application, though they are frequently reported to have high phosphorus (P) sorption capacities. An understanding of the distribution of inherent P in WTR is, however, required, if sorption-desorption processes are to be correctl...

Trout testis cells were incubated with 13H]arginine and lysine and inorganic [32P]phosphate. Histones were extracted with acid and the major fractions (I, IIbl, IIb2, III monomer, and IV) were resolved by chromatography on BioGel P-10. The profile of 32P incorporation was time dependent. When the phosphorylated histones in each of the major fractions were resolved from unphosphorylated species ...
