(Health and Medical Publishing Group, 2017)Background. Studies of electrophoresis testing (serum protein electrophoresis (SPE), urine protein electrophoresis (UPE), immunofixation electrophoresis (IFE)) in a South African (SA) pathology laboratory setting are ... -
The association between vitamin D, vitamin D Binding proteins and VDR polymorphisms in diabetic and non-diabetic patients
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: Introduction: Type 2 diabetes mellitus (T2DM) is by far the most prevalent form of diabetes manifesting with insulin resistance (IR), abnormal pancreatic β-cell function and hyperglycaemia. Evidence from ... -
Platelet, monocyte and neutrophil activation and glucose tolerance in South African Mixed Ancestry individuals
(Nature Research, 2017)Platelet activation has been described in patients with chronic inflammation, however in type 2 diabetes mellitus it remains controversial. We compared levels of platelet leucocyte aggregates, monocyte and granulocyte ... -
