Effects of nitric oxide on novel soybean cystatin gene expression under salt stress in soybean
(University of the Western Cape, 2012)Nitric oxide (NO) has been shown to orchestrate multiple defense responses to both abiotic and biotic stress. Importantly, elevation of nitric oxide content in plants by using nitric oxide generating compounds has been ... -
The effects of nitric oxide on soybean superoxide dismutase activity during osmotic stress
(University of the Western Cape, 2012)Nitric oxide (NO) is a signaling molecule involved in mediating plant responses to various biotic and abiotic stresses. Major abiotic stresses (drought, salinity, cold) induce common cellular responses, causing osmotic ... -
Effects of nucleotide variation on the structure and function of human arylamine n-acetyltransferase 1
(2012)The human arylamine N-acetyltransferase 1 (NAT1) is critical in determining the duration of action and pharmacokinetics of amine-containing drugs such as para-aminosalicylic acid and para-aminobenzoyl glutamate used in ... -
Effects of peer counselling on feeding practices of HIV positive and HIV negative women in South Africa: a randomised controlled trial
(University of the Western Cape, 2011)Promotion of exclusive breastfeeding (EBF), (giving breast milk only without any solids or liquids), has proved to be very challenging in the South African context, although this infant feeding practice has been found to ... -
