The impact of Covid-19 vaccines on male semen parameters: A retrospective cohort study
(University of the Western Cape, 2023)The emergence of SARS-CoV-2 and the subsequent COVID-19 pandemic necessitated the development of adequate vaccines. Despite vaccines being demonstrated to be safe and effective for preventing severe disease and death, ... -
Real-time assessment of interspecies candida biofilm formation
(Bentham Open, 2022-12-30)Background: Candida infections are responsible for increased morbidity and mortality in immunocompromised patients, with Candida having the ability to form highly structured biofilms that protect them from the external ... -
Quantum dot-sensitised estrogen receptor-α-based biosensor for 17β-estradiol
(MDPI, 2023): 17β-estradiol (E2) is an important natural female hormone that is also classified as an estrogenic endocrine-disrupting compound (e-EDC). It is, however, known to cause more damaging health effects compared to other ... -
Computational and preclinical prediction of the antimicrobial properties of an agent isolated from monodora myristica: A novel dna gyrase inhibitor
(MDPI, 2023)The African nutmeg (Monodora myristica) is a medically useful plant. We, herein, aimed to critically examine whether bioactive compounds identified in the extracted oil of Monodora myristica could act as antimicrobial ... -
SysBiolPGWAS: simplifying post-GWAS analysis through the use of computational technologies and integration of diverse omics datasets
(Bioinformatics, 2022)Motivation: Post-genome-wide association studies (pGWAS) analysis is designed to decipher the functional consequences of significant single-nucleotide polymorphisms (SNPs) in the era of GWAS. This can be translated into ... -
Incidence and burden of injury at the Tokyo 2020 Paralympic Games held during the Covid-19 pandemic: A prospective cohort study of 66 045 athlete days
(British Journal of Sports Medicine, 2022)Objective To describe the epidemiology of injuries at the Tokyo 2020 Paralympic Games, including injuries sustained in the new sports of badminton and taekwondo. Methods Injury data were obtained daily via the established ... -
What are psychiatric disorders of people who are incarcerated in France
(Elsevier, 2022)The presence of detainees suffering from psychiatric disorders has been observed since the birth of the modern prison system, and the numbers have fluctuated since then, depending on the evolution of psychiatric facilities ... -
Extending the Hoyle-State Paradigm to 12 C + 12 C Fusion
(American Physical Society, 2022)Carbon burning is a key step in the evolution of massive stars, Type 1a supernovae and superbursts in x-ray binary systems. Determining the 12C þ 12C fusion cross section at relevant energies by extrapolation of direct ... -
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 ... -
