Of 53 isolates of Chaetomium globosum Kunze isolated from corn, manufactured feed, and fiberboard, grown on autoclaved corn, and fed to rats, 25 were lethal within 4 to 6 days. Thirty-six single ascospore cultures of one isolate were uniformly lethal when similarly grown and fed to rats. Incubation of the fungus on corn for 6 to 8 weeks resulted in greater toxicity than shorter incubation times...

Effects of lipid removal on the fine milling and air classification processing of oats were studied. Lipid removal by supercritical carbon dioxide (SC-CO2) extraction enabled concentration of the main components of oats e starch, protein, lipids and cell walls e into specific fractions. Using defatted oats as raw material, the highest b-glucan concentration of the cell wall-enriched fraction wa...

Cyromazine and dicyclanil are both used as insect growth regulators. This paper describes an easy and innovative simultaneous extraction method for residues of cyromazine and dicyclanil in food of animal origin, and a confirmation procedure using UHPLC-MS/MS. The sample was extracted, deproteinised by 1% trichloracetic acid in water-acetonitrile, followed by selective defatting using hexane bas...

BACKGROUND Conventional drugs used to treat diabetes are too expensive, toxic and rarely available to rural communities. This study was aimed at investigating the phytochemical differences and hypoglycaemic effects (α-amylase enzyme inhibition, glucose uptake, GLUT4 translocation and phosphorylation of MAPKs) of non-defatted and defatted acetone leaf extract of Acacia karroo. METHODS Qualitat...

C-reactive protein is a substance which appears in human blood during the acute phase of a variety of infectious diseases as well as during the course of certain non-infectious diseases. The presence of C-reactive protein in serum was first recognized as the result of its property of reacting to form a precipitate with the somatic C polysaccharide of pneumococeus (1). This reaction is responsib...

A confirmatory, highly selective multi-residue method based on liquid chromatography coupled to hybrid high resolution mass spectrometry (LC-Q-Orbitrap) was developed and validated for the determination of 12 regulated coccidiostats in eggs muscle. Particularly, ionophore antibiotics (lasalocid, maduramicin, monensin, narasin, salinomycin semduramicin) synthetic (diclazuril, halofuginone, nicar...
