Ethnic and gender differences regarding the insulin-blood pressure relationship
(Elsevier, 2009)Ageing is associated with increased insulin and C-peptide levels. Due to a lack of data, our first aim was to establish whether this also holds true for Africans from South Africa. Our second aim was to determine whether ... -
An ethnic comparison of arginine dimethylation and cardiometabolic factors in healthy black and white youth: the ASOS and African-PREDICT studies
(MDPI, 2020)Proteinic arginine dimethylation (PADiMe) is a major post-translational modification. Proteolysis of asymmetric and symmetric PADiMe products releases asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA), ... -
Ethnic differences regarding arterial stiffness of 6‐8‐year-old black and white boys
(Wolters Kluwer, 2017)Objectives: Vascular deterioration is suggested to occur earlier in black than white populations, thereby increasing their risk for developing hypertension. To establish whether this is the case, we compared different ... -
Ethnic disparity in defensive coping endothelial responses: the SABPA study
(Elsevier, 2015)Objectives: Defensive coping (DefS) in Blacks has been associated with greater cardiovascular risk than in their White counterparts. We examined associations between endothelial function mental stress responses and markers ... -
Ethnic identification as contributor to the development of moral identity in child-headed households
(Taylor & Francis, 2013)This study explored whether ethnic membership was a core construct in the moral identity development of adolescents in Zulu child-headed households. A convenience sample of 60 participants (31 male and 29 female) were ... -
Ethnic-specific correlations of Visfatin with circulating markers of endothelial inflammation and function
(Wiley, 2009)Sub-Saharan Africa is afflicted by high hypertension prevalence that is expected to rise even further along with increasing obesity rates. The present study aimed to investigate the role of visfatin in obesity and to explore ... -
Ethnic-specific relationships between haemostatic and oxidative stress markers in black and white South Africans: the SABPA study
(Taylor & Francis, 2015)Haemostatic– and oxidative stress markers are associated with increased cardiovascular risk. In the black population, evidence exists that both an imbalance in the haemostatic system and oxidative stress link with the ... -
Ethnicity and arterial stiffness
(AHA, 2020)Early vascular aging reflects increased arterial stiffness of central blood vessels at young chronological ages and powerfully predicts cardiovascular events and mortality, independent of routine brachial blood pressure ... -
Ethnicity-specific changes in cardiac troponin t in response to acute mental stress and ethnicity-specific cutpoints for the R wave of the aVL lead: the SABPA study
(Oxford Univ Press, 2019)Acute mental stressor–induced cardiac stress responses might contribute to excessive myocardial strain and resultant cardiovascular episode risk. We assessed ethnicity-specific acute cardiac stress (by measuring cardiac ... -
Ethnicity-specific differences in L-arginine status in South African men
(Nature Publishing Group, 2012)The aetiology for an increasing incidence of hypertensive cardiovascular disease amongst Africans in southern Africa is unclear. Hypertension may be induced by inadequate release of L-arginine-derived nitric oxide impairing ... -
The eudaimonic and hedonic components of happiness: qualitative and quantitative findings
(Springer, 2011)This paper illustrates a new project developed by a cross-country team of researchers, with the aim of studying the hedonic and eudaimonic components of happiness through a mixed method approach combining both qualitative ... -
Eudragit® L100/N-trimethylchitosan chloride microspheres for oral insulin delivery
(MDPI, 2013)Effective oral delivery of protein and peptide drugs remains an active topic in scientific research. In this study, matrix type microspheres were prepared with Eudragit® L100 containing N-trimethylchitosan chloride to ... -
Euphorbias of South Africa: two new phorbol esters from Euphorbia bothae
(South African Bureau for Scientific Publications, 2010)Two known phorbol esters, 12-deoxyphorbol-13-isobutyrate-20-acetate (1) and 12-deoxyphorbol-13-(2-methylbutyrate)-20-acetate (2), and two new phorbol esters, 12-deoxyphorbol-13-isobutyrate-16-angelate-20-acetate (3) and ... -
European cardiovascular mortality over the last three decades: evaluation of time trends, forecasts for 2016
(Società Editrice Universo, 2017)Background. The circulatory diseases, in particular ischemic heart diseases and stroke, represent the main causes of death worldwide both in high income and in middle and low income countries. Our aim is to provide a ... -
Evaluating several biomarkers as predictors of aortic stiffness in young and older Africans, not consuming alcohol based on self-report
(Elsevier, 2018)Aims Black populations from sub-Saharan Africa have a high prevalence of cardiovascular disease, which places significant strain on public health systems. Aortic stiffness is a prominent risk factor for cardiovascular ... -
Evaluating the integrated management of childhood illness counselling skills of professional nurses in the North West Province of South Africa
(AOSIS, 2018)Background: The Integrated Management of Childhood Illness (IMCI) strategy provides guidelines for supporting and improving the health system to reduce under-5 children’s mortality rates. This strategy specifically assists ... -
Evaluation and optimization of synthetic routes from dihydroartemisinin to the alkylamino-artemisinins artemiside and artemisone: a test of N-glycosylation methodologies on a lipophilic peroxide
(Elsevier, 2018)10-Alkylamino-artemisinins including artemiside and artemisone display enhanced activities against malaria. Earlier, dihydroartemisinin (DHA) TMS ether was converted by trimethylsilyl bromide into the 10-β-bromide that ... -
The evaluation and quantification of respirable coal and silica dust concentrations: a task-based approach
(Taylor & Francis, 2014)Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts containing crystalline silica. The purpose of this ... -
The evaluation of 1,4-benzoquinones as inhibitors of human monoamine oxidase
