Chemical fractionation and heavy metal accumulation in maize (Zea mays) grown on chromated copper arsenate (CCA) contaminated soil amended with cow dung manure

Cow dung used as soil amendments and a sequential chemical speciation (six steps) procedure were used to predict the uptake of Cr, Cu and As by maize (Zea mays) plant in chromated copper arsenate (CCA) contaminated soil. A pot experiment containing the contaminated soil samples with different percentage levels of amendments and control (no amendment) was set up. The relative concentrations of the metals in the CCA...

Ethnomedicinal plants and other natural products with anti-HIV active compounds and their putative modes of action

The use of ethnomedicines to manage HIV/AIDS has recently gained public interest, although harmonization with official HIV/AIDS policy remains a contentious issue in many countries. Plants and other natural products present a large repertoire from which to isolate novel anti-HIV active compounds. In this literature survey, 55 plant families containing 95 plant species, and other natural products, were found to contain...
