A cross-sectional analysis of the association between age and gender and prescribed minimum benefit chronic disease list conditions among South Africans with concomitant hypertension, diabetes and dyslipidaemia
(AJOL, 2017)Background: Prescribed Minimum Benefit Chronic Disease List (PMB CDL) conditions are a regulated list of conditions most common to South Africa. Objectives: To investigate the prevalence and association between PMB CDL ... -
A cross-sectional survival analysis regression model with applications to consumer credit risk
(SASA, 2017)When performing long-range survival estimations, longitudinal survival analysis methods such as Cox Proportional Hazards (PH) and accelerated lifetime models may produce estimates that are outdated. This paper introduces ... -
The cross-tissue metabolic response of abalone (Haliotis midae) to functional hypoxia
(The Company of Biologists, 2018)Functional hypoxia is a stress condition caused by the abalone itself as a result of increased muscle activity, which generally necessitates the employment of anaerobic metabolism if the activity is sustained for prolonged ... -
A crossed product approach to Orlicz spaces
(London Mathematical Society, 2013)We show how the known theory of non-commutative Orlicz spaces for semifinite von Neumann algebras equipped with an faithful normal semifinite trace may be recovered using crossed product techniques. Then using this as a ... -
Cry1Ab protein from Bacillus thuringiensis and MON810 cry1Ab–transgenic maize exerts no adjuvant effect after airway exposure
(Wiley, 2015)The genetically modified (GM) maize event MON810 has been inserted with a processed version of the transgene, cry1Ab, derived from the soil bacterium Bacillus thuringiensis (Bt) to express proteins with insecticidal ... -
Cryotherapy reinvented: application of phase change material for recovery in elite soccer
(Human kinetics, 2018)Purpose: To examine whether donning lower-body garments fitted with cooled phase change material (PCM) would enhance recovery after a soccer match. Methods: In a randomized, crossover design, 11 elite soccer players from ... -
CTA 102 - Year over year receiving you
(Sissa Medialab, 2019)The FSRQ CTA 102 (z=1.032) has been tremendously active over the last few years. During its peak activity lasting several months in late 2016 and early 2017, the gamma-ray and optical fluxes rose by up to a factor 100 ... -

The Cuito catchment of the Okavango system: a vascular plant checklist for the Angolan headwaters
(Pensoft, 2018)This paper aims to provide a baseline for conservation planning by documenting patterns of plant diversity and vegetation in the upper catchment of the Cuito River. 417 species are recorded from this region. Nine of these ... -
Culicoides species composition and environmental factors influencing African horse sickness distribution at three sites in Namibia
(Elsevier, 2016)African horse sickness (AHS) is one of the most lethal infectious, non-contagious, vector-borne disease of equids. The causative agent, African horse sickness virus (AHSV) is transmitted via Culicoides midges (Diptera: ... -
Cultural coping as a risk for depression and hypertension: the SABPA prospective study
(Clinics Cardive, 2018)Objectives: In past studies, a lack of social support has been associated with cardiovascular disease (CVD) risk, particularly in black Africans. However, whether or not coping strategies have beneficial effects on blood ... -
Curcumin rescues a PINK1 knock down SH-SY5Y cellular model of Parkinson’s disease from mitochondrial dysfunction and cell death
(Springer, 2017)Parkinson’s disease (PD) is a neurodegenerative disorder characterised by the loss of dopaminergic neurons in the substantia nigra. Mutations in the PINK1 gene result in an autosomal recessive form of early-onset PD. ... -
Current and next-generation bluetongue vaccines: requirements, strategies, and prospects for different field situations
(Taylor & Francis, 2017)Bluetongue virus (BTV) causes the hemorrhagic disease bluetongue (BT) in ruminants. The best way to control outbreaks is vaccination. Currently, conventionally modified-live and inactivated vaccines are commercially ... -
Current conservation status of the Blue Swallow Hirundo atrocaerulea Sundevall 1850 in Africa
(Taylor & Francis + NISC, 2015)The global Blue Swallow Hirundo atrocaerulea was classified as Vulnerable in 2010 on account of its small and rapidly declining population estimated at less than 1 500 pairs. We undertook this study to gain a better ... -
Current distribution and population size of the Blue Swallow Hirundo atrocaerulea in the southern Tanzanian highlands
(Taylor & Francis, 2016)Two surveys of Blue Swallows were conducted in the southern Tanzanian highland grasslands in order to determine the habitat preferences and estimate the size of this subpopulation. During the 2008/09 and 2012 surveys, a ... -
Current evidence concerning the psychological and employment contract of sport coaches in South Africa
(LAM Publications; AJOL; Sabinet, 2013)The entire contract spectrum that governs the employment relationship ranges from being strictly legal, as governed by the employment law and more specifically the employment contract, to purely psychological, where scholars ... -
Current sheets, magnetic islands, and associated particle acceleration in the solar wind as observed by Ulysses near the ecliptic plane
(IOP Publishing, 2019)Recent studies of particle acceleration in the heliosphere have revealed a new mechanism that can locally energize particles up to several MeV nucleon–1. Stream–stream interactions, as well as the heliospheric current sheet ... -
