The altered fatty acylcarnitines, amino acids and organic acids detected in tuberculosis patient urine
(North-West University (South Africa), Potchefstroom Campus, 2018)Mycobacterium tuberculosis is estimated to infect approximately one-third of the world’s population, which can lead to an active, symptomatic disease called tuberculosis (TB), or to asymptomatic states, often referred ... -
Comparing predefined derivatisation parameters for GC-MS analysis of selected organic acids
(North-West University, 2019)Organic acids are intermediates of numerous biochemical pathways in living organisms. They can be detected in biological fluids which make it possible to obtain a representative profile of the functioning of biochemical ... -
Long-term assessment of aerosol chemical composition in the interior of South Africa
(North-West University (South Africa). Potchefstroom Campus, 2019)The impacts of atmospheric particulate matter (PM) are co-determined by chemical composition. PM with aerodynamic diameter ≤ 2.5 μm (PM2.5) typically contains a significant fraction of organic- (OC), elemental carbon (EC), ... -
A metabolomics study of selected perturbations of normal human metabolism
(North-West University, 2010)Metabolism is an integrated network of biochemical pathways involving a series of enzymecatalysed anabolic or catabolic reactions in cells. Metabolites are chemical compounds that are involved in or are products ... -
Re-assessment and optimisation of an organic acid extraction method for automation
(North-West University (South Africa), Potchefstroom Campus, 2017)Sample preparation is a necessary prerequisite for GC/MS analysis of urinary organic acids for clinical diagnosis of inborn errors of metabolism (IEM). The sample clean-up step in the analytical process poses a challenge. ...
