In this quantum chemical investigation, NH(3) physisorption onto a model of copper sulfate impregnated silica is compared with pure silica and copper sulfate adsorbents. The physisorption process is modeled as direct binding of the NH(3) molecule to the adsorption site of the dry adsorbents and as displacement of a H(2)O molecule by NH(3) in the hydrated complexes. The surface of silica is repr...
In cells undergoing oxidative stress, DNA damage may result from attack by .OH radicals produced by the Fenton reaction, and/or by nucleases activated by nuclear calcium. In the present study, the participation of these two mechanisms was investigated in HeLa cells. Nuclear-targeted aequorin was used for selectively monitoring Ca2+ concentrations within the nuclei ([Ca2+]n), in conjunction with...
In this study, the interaction between iron and copper on growth parameters (plant height, fresh weight of roots, stem’s length, fresh weight of shoots, fresh and dry weight of seeds), total proteins and the antioxidant enzymes activity in Cuminum cyminum L. were investigated. This experiment was carried out in completely randomized blocks with 9 treatments in 3 repetitions. Plants were tre...
Background: Copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. Fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. Methods: In this study, juvenile species of silver carp with average weight of 200gr...
Fiber extracted from castor plant is a bast fiber like hemp, jute, flax and kenaf. Based on the chemical constitutes; physical properties of these eco-friendly fibers agro waste are used in making different materials union fabrics reinforcement materials. In present study, was dyed with Eclipta prostrata extract evaluated for colorfastness color strength properties. The pre, simultaneous post-m...
A brown-colored fraction containing heme was separated from the lipoprotein-free plasma of Japanese eel (Anguilla japonica). This fraction prevented the oxidation of very-low-density lipoprotein incubated with CuSO4 ranging in concentration from 0.5 to 3 μM. The antioxidant activity seemed to derive from the heme-binding proteins of the brown-colored fraction.
Twenty-four crossbred barrows (average BW, 70.8 kg) were used to compare the digestibility of dry matter and the mineral absorption and retention by pigs fed two Cu sources. Dietary treatments were 1) basal (B) (16% CP corn-soybean meal-based diet, 36 mg/kg of Cu), 2) B + 200 mg/kg of Cu from CuSO4.5 H2O (CuSO4), and 3) B + 200 mg/kg of Cu from a copper lysine complex (CuLys). All diets contain...
Pre-donation screening declarations and hemoglobin (Hb) testing are measures used to determine the quality of donated blood. The copper sulphate (CuSo4) method used to screen for blood abnormalities can give inaccurate results if strict quality control is not applied. Blood donors who are carriers of thalassemia and those with mild iron deficiency anemia (IDA) are usually asymptomatic and frequ...
