Copper is a key element affecting blood vessel growth and muscle development. However, the ions released from Cu salts are toxic. Given their specific physicochemical properties, nanoparticles of Cu (NanoCu) may have different bioactivity and affect the development of blood vessel and muscles in a different manner than Cu salts. The objective of the study was to evaluate the influence of NanoCu...

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 ...
