Antinociceptive, anti-inflammatory and antipyretic activities of the leaf methanol extract of ruta graveolens l. (rutaceae) in mice and rats
(African Networks Ethnomedicines, 2014)Ruta graveolens has been used to treat toothache, earache, rheumatism and fever with little scientific evidence corroborating these uses. The leaf methanol extract of Ruta graveolens was evaluated for antinociceptive ... -
Investigation of distinct gene expression profile patterns that can improve the classification of intermediate-risk prognosis in AML patients
(Frontiers Media, 2023)Acute myeloid leukemia (AML) is a heterogeneous type of blood cancer that generally affects the elderly. AML patients are categorized with favorable-, intermediate-, and adverse-risks based on an individual’s genomic ... -
A NSFD method for the singularly perturbed Burgers-Huxley equation
(Frontiers Media, 2023)This article focuses on a numerical solution of the singularly perturbed Burgers-Huxley equation. The simultaneous presence of a singular perturbation parameter and the nonlinearity raise the challenge of finding a reliable ... -
Semi-analytic forecasts for Roman – the beginning of a new era of deep-wide galaxy surveys
(Oxford University Press, 2023)The Nancy Grace Roman Space Telescope, NASA’s next flagship observatory, will redefine deep-field galaxy survey with a field of view two orders of magnitude larger than Hubble and an angular resolution of matching quality. ... -
Scenarios analysis using water-sensitive urban design principles: A case study of the Cape Flats Aquifer in South Africa
(Springer, 2020)A feasibility assessment was undertaken on the application ofwater-sensitive urban design (WSUD) for the Cape Flats Aquifer in Cape Town, South Africa, at the local scale. The study contributes towards the planning of ... -
Sandstone reservoir zonation of the north-western Bredasdorp Basin South Africa using core data
(Elsevier, 2021)This study delineates sandstone reservoir flow zones in the north-western Bredasdorp Basin, offshore South Africa, using conventional core porosity and permeability data. The workflow begins by integrating sedimen- tology ... -
A fitted numerical method for parabolic turning point singularly perturbed problems with an interior layer
(Wiley, 2019)The objective of this paper is to construct and analyzea fitted operator finite difference method (FOFDM) forthe family of time-dependent singularly perturbed parabolicconvection–diffusion problems. The solution to the ... -
Some meta-cayley graphs on dihedral groups
(Springer, 2019)In this paper, we define meta-Cayley graphs on dihedral groups. We fully determine the automorphism groups of the constructed graphs in question. Further, we prove that some of the graphs that we have constructed do not ... -
The effect of anthropogenic noise and weather conditions on male calls in the bladder grasshopper Bullacris unicolor
(Taylor and Francis Group, 2021)Acoustic communication in animals relies upon specificcontextsandenvironments for effective signal transmission. Increasing anthropo-genic noise pollution and different weather conditions can disruptacoustic communication. ... -
Antibacterial activity of rationally designed antimicrobial peptides
(Hindawi, 2020)Many infectious diseases are still prevalent in the world’s populations since no effective treatments are available to eradicate them. e reasons may either be the antibiotic resistance towards the available therapeutic ... -
Examining inequality of opportunity in the use of maternal and reproductive health interventions in Sierra Leone
(Oxford University Press, 2020)Poor countries, such as Sierra Leone, often have poor health outcomes, whereby the majority of the population cannot access lifesaving health services. Access to, and use of, maternal and reproductive health services is ... -

A weighted bootstrap approach to logistic regression modelling in identifying risk behaviours associated with sexual activity
(Taylor and Francis Group, 2019)The latest population estimates released by Statistics South Africa indicate that 25.03% of alldeaths in 2017 in South Africa were AIDS-related. Along with these results, it is also reportedthat 7.06% of the population ... -
Modeling the dynamics of an epidemic under vaccination in two interacting populations
(Hindawi, 2012)Mathematical modeling of the numerical evolution of infectious diseases has become an important tool for disease control and eradication when possible. Much work has been done on the problem of how a given population is ... -
Dark energy homogeneity in general relativity: Are we applying it correctly?
(Springer, 2016)Thus far, there does not appear to be an agreed (or adequate) definition of homogeneous dark energy (DE). This paper seeks to define a valid, adequate homogeneity condition for DE. Firstly, it is shown that as long as ... -
Cytotoxic and cell cycle arrest properties of two steroidal alkaloids isolated from Holarrhena floribunda (G. Don) T. Durand & Schinz leaves
(BMC, 2019)The plant Holarrhena floribunda (H. floribunda; G. Don) is indigenous to sub-Saharan Africa and is traditionally used to treat several ailments. The present study was carried out to isolate and characterize bioactive ... -
Describing medicine therapy management of type 2 diabetes mellitus at primary health care facilities in Cape Town
(AOSIS, 2019)Rational medicine use aims to optimise chronic disease management and prevent episodes of hospitalisation that economically burden the health care system. Diabetes mellitus is one of the most prevalent chronic diseases ... -
A low-cost flow cytometric assay for the detection and quantification of apoptosis using an anionic halogenated fluorescein dye
(Future Science Group, 2008)We describe here a technical improvement of an established colorimetric method used to detect and measure the occurrence of apoptosis in mammalian cells during in vitro cell culture. This assay uses an anionic halogenated ... -
Infaunal benthic communities from the inner shelf off southwestern Africa are characterised by generalist species
(Public Library Science, 2015)Infaunal communities of benthic macro-organisms ( 1mm length) were studied from 81 samples collected across nine sites to the north and south of the Orange River in the Benguela upwelling ecosystem in 2003, with a view ... -
Exploring the implications of a needs-based pharmacy education framework modelled on population health: Perspective from a developing country
(MDPI, 2019)Globally, health education reform is directing efforts to strengthen the health system through collaboration between health education and health services. However, collaborative efforts vary between developed and developing ...
