Assessing the effects of biochar as an ameliorant for biopesticide polluted soils utilising earthworms
(North-West University (South Africa), 2023)Two plant biopesticides, Bidens pilosa L. and Tagetes minuta L., were investigated for possible effects on earthworms and soil enzymatic activity, compared to the conventional pesticide, Fenamiphos. The efficacy of biochar ... -
The effect of fumigants on earthworms (Eisenia andrei) and soil microbial communities
(North-West University, 2015)Biofumigation is an important crop protection practice that uses a plant’s natural defence mechanisms to control agricultural crop pathogens and diseases. Glucosinolates are volatile compounds found in most Brassica species ... -
Establishing the comet assay to determine the effects of different perturbations on DNA repair capacity
(North-West University, 2011)Single cell gel electrophoresis (SCGE), more commonly known as the Comet assay, is an uncomplicated, affordable and versatile method for investigating DNA damage and repair. Existing comet–assay based methods were modified ... -
A study of the early DNA methylation events in oxidative stressed cultured mammalian cells
(North-West University, 2012)Cells are continuously exposed to reactive oxygen species (ROS) causing oxidative stress. Cells can withstand and counteract ROS using defence mechanisms which range from free radical scavengers, antioxidant enzymes and ...
