OBJECTIVE To identify a contrast material that could be used as a dummy marker for magnetic resonance imaging. MATERIALS AND METHODS Magnetic resonance images were acquired with six different catheter-filling materials-water, glucose 50%, saline, olive oil, glycerin, and copper sulfate (CuSO4) water solution (2.08 g/L)-inserted into compatible computed tomography/magnetic resonance imaging ri...

The aging process is characterized by progressive accumulation of damaged biomolecules in the endoplasmic reticulum, as result of increased oxidative stress accompanying cellular senescence. In agreement, we hypothesized that WI-38 human cellular models of replicative senescence and stress-induced premature senescence (SIPS) induced by hydrogen peroxide (H2O2-SIPS) or copper sulfate (CuSO4-SIPS...

Different concentrations of selected heavy metals in the form of cadmium chloride (CdCl2), copper sulphate (CuSO4), lead nitrate (Pb (NO3)2) and mercuric nitrate (Hg (NO3)2) were tested against immature and mature stage of C. pipiens to assess the toxicity, LC50, total carbohydrate and lipid content. The survival potential of 2 instar larvae was highly affected by the contamination with the tes...

Tests were conducted to determine the concentrations of copper sulfate needed to kill Flavobacterium psychrophilum, the cause of bacterial coldwater disease, either in vitro or on Rainbow Trout Oncorhynchus mykiss eggs. For the in vitro test, a plastic strip dipped in a solution of F. psychrophilum was exposed for 15 min to copper sulfate solutions of 0, 1, 5, 10, 20, 35, 50, 75, or 100 mg/L. B...

A few studies have investigated the interaction between copper toxicity and water pH in fishes, but little is known about the effects of acidic pH on the toxicity of copper nanoparticles (Cu-NPs). This study aimed to describe the sub-lethal toxic effects of Cu-NPs compared to CuSO4 at neutral and acidic water pH values in juvenile rainbow trout. Fish were exposed in triplicate (3 tanks/treatmen...

A method is described whereby dielectrophoresis of algal cells is used to perform rapid water quality analysis, specifically detecting the presence of CuSO4. The dielectric collection spectrum of the fresh water alga Selenastrum capricornutum was determined for a range of concentrations of CuSO4 from 25 mg L(-1) to 0.25 mg L(-1) for exposure times of 15 min and 18 h. In all cases increasing the...

present experiment was carried out to check the effect of different concentrations of sucrose (2, 4, 6%), ga 3 (25, 50, 75 ppm) and combination of sucrose and cuso4 (2% + 200, 4% + 300, 6% + 400 ppm), sucrose and ga 3 (2% + 25 ppm), (4%+50 ppm), (6%+75 ppm) on keeping quality and vase life of carnation cv. ‘eskimo’. some postharvest characteristics such as vase life, total soluble solids (tss),...

The prevention and control of root-knot nematode disease is a worldwide challenge there are not many varieties pesticides for control. To meet the huge market demand, development new nematicides urgently needed. lethal effects soil fumigant dimethyl disulfide (DMDS) mixed with chemical compounds copper sulfate (CuSO4) ammonium bicarbonate (NH4HCO3) on Meloidogyne incognita were tested using imm...

The aim of this study was to explore the heavy-metal resistance and hydrocarbonoclastic potential of microorganisms in a hypersaline soil. For this, hydrocarbonoclastic microorganisms were counted on a mineral medium with oil vapor as a sole carbon source in the presence of increasing concentrations of ZnSO4, HgCl2, CdSO4, PbNO3, CuSO4, and Na2HAsO4. The colony-forming units counted decreased i...

To date, studies of the toxicity of engineered nanoparticles (NPs) in fish have not fully considered effects on olfactory-mediated behaviours, despite their ecological importance. In this study the effects of copper NPs (Cu NPs) on the anti-predator behavioural responses of juvenile rainbow trout (Oncorhynchus mykiss) to trout alarm substance was investigated. Individual fish were exposed for 1...
