A comparative study on the effect of excess copper (Cu) supplied through leaves and root treatments in soybean plants is presented. Although Cu was accumulated in leaves upon both treatments, important differences were observed between Cu treatment of leaves and Cu supplementation in hydroponic medium. The application of 50 μM CuSO4 on leaves increased chlorophyll content, oxygen evolution acti...

We isolated the highly potent attachment-inhibitors (three times more active than standard CuSO4 in the blue mussel assay), trans-6-, 8-, and 10-shogaols, from a hexane extract of the roots of ginger, Zingiber officinale Roscoe. Trans-8-shogaol showed the highest antifouling activity comparable with that of tributyltin fluoride (TBTF), which is recognized as one of the most effective antifoulin...

Natural fiber-made apparel dyed with natural dyes is drawing consumer attention because of the possible toxic and health hazards associated fabric synthetic dyes. However, many textile products available in market could pose a risk use heavy metals as dye-complexing agent. In this work, jute fabrics were multi-functionalized gallotannin (GT), using ferrous sulfate (FeSO4), calcium chloride (CaC...

Background: The National Blood Transfusion Service (NBTS) in Tanzania uses the Copper Sulphate (CuSO4) gravimetric method to estimate hemoglobin (Hb) blood donors. However, this and other point-of-care methods, including HemoCue, may provide false results. Therefore, study aimed evaluate performance of CuSO4 HemoCue methods for Hb estimation compared with automated haematology analyzer (AHA). M...

We investigated effects of fluvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, and its major metabolites, M2 and M4, on CuSO4-induced low-density lipoprotein (LDL) oxidation and cholesteryl ester accumulation in mouse peritoneal macrophages. All the test compounds inhibited LDL oxidation, and M2 had the most potent effect comparable to vitamin E. When LDL was pre...

BACKGROUND A method to evaluate the antioxidant capacity of high-density lipoprotein (HDL) was developed and standardized. METHODS This method measure conjugated diene (CD) formation and electrophoretic mobility of low-density lipoprotein (LDL) in agarose gels in the presence and absence of HDL. HDL was isolated from 1 mL of plasma within 24 hours and oxidation assays were performed within 6 ...

The present work demonstrates the heavy metal resistance and detoxification of Cr(VI) by the probiotic actinobacterial cultures isolated from chicken and goat feces. The actinobacterial isolates were screened for heavy metal resistance by qualitative, semiquantitative assays and Cr(VI) biosorption was determined by analytical techniques such as atomic absorption spectrophotometry and Fourier tr...

The heavy metal tolerance in corn (Zea mays L.) var. ‘Neelum’ was assessed at germination and seedling growth after having subjected it to different concentrations of CuSO4 and ZnSO4. Germination was not affected by any of the metal tested, whereas initial growth was strongly inhibited by increasing concentrations of ZnSO4. Seedlings developed toxicity symptoms in the presence of both metals bu...
