In the present study, thirty-five Nellore bulls were used to determine the effects of two levels and two sources (organic and inorganic) of Cu supplementation on the oxidative stability of lipids, measured by the thiobarbituric acid-reactive substance (TBARS) test, meat colour and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) enzyme activities. The following treatments were use...

Anchovy oil is a very suitable supplementary ingredient for fish feeds due to the essential fatty acid composition. The acute toxicity of zinc and copper ions for rainbow trout (Oncorhynchus mykiss Walbaum 1792) were evaluated by static bioassays. The average weight and lenght of fish used in the zinc experiments were 3,02 ±0.21 g and 6.52 ±0.12 cm, respectively, while the tests with copper ion...

The aim of this study was to characterise biomarker responses in three-spined sticklebacks exposed to copper. For this purpose, adult sticklebacks were exposed for 3 weeks to copper sulphate at 0, 25, 100 and 200μgL(-1) as Cu. At days 4, 8, 12 and 21, several parameters were measured including liver, gonad and spleen somatic indexes, hepatic biomarkers (catalase (CAT), superoxide dismutase (SOD...

Chemical cross-linking reagents are valuable tools for studying the structural relationships between proteins in complexes and organelles. Copper phenanthroline is an oxidizing agent that has been used to cross-link membrane proteins via adjacent free thiol groups. In the courseof such topographical studies of rabbit liver microsomal preparations, we noted that incubation of microsomal preparat...

Solid waste dump site-based pollution is one of the colossal health concerns globally due to presence cellulose, starch, protein, and lipids, which a perfect nutrient for development biodegrading potential microbes. The current study aimed determine productive microorganisms biodegradation. Ten samples were collected from different areas Karachi sites. identification characterization isolates d...

Forty-five SA Mutton Merino ewes, 2 to 5 years of age, were divided into three groups. Although all ewes received the same basic diet, the diet of one group (group M) was supplemented with molybdenum and that of another group (MS) with molybdenum and sulphate to induce a secondary copper deficiency. The third group (C) served as a control, and received the basic diet supplemented with copper. A...
