Obesity and male infertility: Mechanisms and management
(Blackwell Publishing Ltd, 2021)Obesity is considered a global health problem affecting more than a third of the population. Complications of obesity include cardiovascular diseases, type 2 diabetes mellitus, malignancy (including prostatic cancer), ... -
Obesity and metabolic syndrome associated with systemic inflammation and the impact on the male reproductive system
(John Wiley & Sons Ltd, 2019)Obesity and metabolic syndrome (MetS) are global epidemics, driven by an obe‐sogenic environment. This is mediated by complex underlying pathophysiology, in which chronic inflammation is an important aetiological and ... -
Obesity in South Africa: Challenges for government and health professionals
(Nutrition Society, 2005)OBJECTIVES: To review data on the prevalence, causes and health consequences of obesity in South Africa and propose interventions to prevent and treat obesity and related outcomes. METHODS: Data from existing literature ... -
Obesity in South Africa: The South African Demographic and Health Survey
(Nature Publishing Group, 2002)To ascertain the anthropometric profile and determinants of obesity in South Africans who participated in the Demographic and Health Survey in 1998. RESEARCH METHODS AND PROCEDURES: A sample of 13,089 men and women (age, ... -
Obesity is associated with increased seminal insulin and leptin alongside reduced fertility parameters in a controlled male cohort
(BioMed Central, 2014)Obesity appears to be associated with male reproductive dysfunction and infertility, although this has been inconsistent and inconclusive. Insulin and leptin are known mediators and modulators of the hypothalamus-pituitary-testes ... -
Objective structured clinical examination: Do first-year nursing students perceive it to be stressful?
(AOSIS, 2023)The Objective Structured Clinical Examination (OSCE) is widely accepted as an effective means of assessing clinical competence and nursing skills. There is, however, little existing knowledge on how first-year nursing ... -
Obligation to family during times of transition: care, support and the response to HIV and AIDS in rural South Africa
(Taylor & Francis, 2016)In rural South Africa, high HIV prevalence has the potential to affect the care and support that kin are able to provide to those living with HIV. Despite this, families seem to be largely resilient and a key source of ... -
Observation of the 0+ 2 and γ bands in 98Ru, and shape coexistence in the Ru isotopes
(Elsevier, 2020)Excited states in 98Ru were investigated using γ-ray spectroscopy following the β-decay of 98Rh, and via the 100Ru(p,t) reaction. Combining the results from the two experiments, two states were revised to have spin-parity ... -
The observation of vibrating pear-shapes in radon nuclei
(nature communications, 2019)There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipole moments of atoms, which would indicate ... -
Observations on euphausiid communities of the south coast of South Africa
(NISC (Pty) Ltd and Taylor& Francis, 1995)A total of 24 species of euphausiid was collected during a survey along the South African south coast during January 1992. Communities over the Agulhas Bank were of low diversity and abundance and were dominated by Nycliphanes ... -
Observations on the ecology of Pleurobrachia pileus (Ctenophora) in the southern Benguela ecosystem
(NISC (Pty) Ltd and Taylor & Francis, 2003)The vertical distribution, abundance and size composition of a population of Pleurobrachia pileus was studied during a six-day drogue study conducted off the west coast of South Africa in February 1995. The population was ... -
Observations on the pelagic decapod Pasiphaea semispinosa in the Benguela upwelling ecosystem
(NISC and Taylor & Francis, 1994)Information on vertical and horizontal distribution patterns, abundance and morphology of the decapod Pasiphaea semispinosa in the Benguela upwelling system is presented. P. semispinosa is the dominant pelagic decapod in ... -

(Taylor & Francis, 2014)Using a longitudinal ethnographic study of the linguistic landscape (LL) in Observatory's business corridor of Lower Main Road, the paper explores changes brought about by the influx of immigrant Africans, their artefacts ... -
The observed galaxy bispectrum from single-field inflation in the squeezed limit
(IOP Publishing, 2018)Using the consistency relation in Fourier space, we derive the observed galaxy bispectrum from single- eld in ation in the squeezed limit, in which one of the three modes has a wavelength much longer than the other two. ... -
Observing relativistic features in large-scale structure surveys - I. Multipoles of the power spectrum
(Oxford University Press, 2021)Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation and the possibility of constraining novel ... -

Obstetric violence within students’ rite of passage: The reproduction of the obstetric subject and its racialised (m)other
(UNISA Press, 2021)Building on the work of Mbembe (2019) and Silva (2007), we theorise how the obstetric institution can still be considered fundamentally modern, that is, entangled with colonialism, slavery, bio- and necropolitics ... -
