Determination of paracetamol on electrochemically reduced graphene oxide–antimony nanocomposite modified pencil graphite electrode using adsorptive stripping differential pulse voltammetry
(MDPI, 2022)A simple, highly sensitive, accurate, and low-cost electrochemical sensor was developed for the determination of over-the-counter painkiller, paracetamol (PC). The enhanced sensing capabilities of the developed sensor ... -
Single nucleotide polymorphisms in amlodipine-associated genes and their correlation with blood pressure control among South African adults with hypertension
(MDPI, 2022)This study describes the single nucleotide polymorphisms (SNPs) in amlodipineassociated genes and assesses their correlation with blood pressure control among South African adults with hypertension. Methods: In total, ... -
Water quality prediction based on multi-task learning
(MDPI, 2022)Water pollution seriously endangers people’s lives and restricts the sustainable development of the economy. Water quality prediction is essential for early warning and prevention of water pollution. However, the nonlinear ... -
Flavonoid and phenolic acid profiles of dehulled and whole vigna subterranea (l.) Verdc seeds commonly consumed in South Africa
(MDPI, 2022)Bambara groundnut (BGN) is an underexploited crop with a rich nutrient content and is used in traditional medicine, but limited information is available on the quantitative characterization of its flavonoids and phenolic ... -
Monkeypox during Covid-19 era in Africa: Current challenges and recommendations
(Elsevier, 2022)In May 2022, monkeypox virus (MPXV) outbreak was confirmed amid the coronavirus disease 2019 (COVID-19) pandemic in many parts of the world including Africa. This is the largest outbreak since monkeypox (MPX) was first ... -
The flexible, extended coil of the pdz-binding motif of the three deadly human coronavirus e proteins plays a role in pathogenicity
(MDPI, 2022)The less virulent human (h) coronaviruses (CoVs) 229E, NL63, OC43, and HKU1 cause mild, self-limiting respiratory tract infections, while the more virulent SARS-CoV-1, MERS-CoV, and SARS-CoV-2 have caused severe outbreaks. ... -
A comparison of multi-phase magnetic field tracers in a high-galactic latitude region of the filamentary interstellar medium
(IOP Publishing, 2022)Understanding how the Galactic magnetic field threads the multiphase interstellar medium (ISM) remains a considerable challenge, as different magnetic field tracers probe dissimilar phases and field components. We search for ... -
Prevalence, patterns and determinants of dyslipidaemia among South African adults with comorbidities
(Nature Research, 2022)The present study assessed the prevalence, patterns and determinants of dyslipidaemia among South African adults with multi-morbidities. In this study, 614 individuals with DM and hypertension were recruited. Dyslipidaemia ... -
Fabrication of AgCu/TiO2 nanoparticle-based sensors for selective detection of xylene vapor
(Royal Society of Chemistry, 2022)The design and fabrication of innovative nanostructured materials that could display improved sensitivity, selectivity, and rapid response/recovery characteristics still present significant scientific challenges. Herein ... -
A comparison of ensemble and deep learning algorithms to model groundwater levels in a data-scarce aquifer of Southern Africa
(MDPI, 2022)Machine learning and deep learning have demonstrated usefulness in modelling various groundwater phenomena. However, these techniques require large amounts of data to develop reliable models. In the Southern African ... -
Consequences of using a smooth cosmic distance in a lumpy Universe. I.
(American Physical Society, 2022)How do we appropriately fit a model based on an idealised Friedmann-Lemaˆıtre Robertson-Walker spacetime to observations made from a single location in a lumpy Universe? We address this question for surveys that measure ... -
Synthesis of stabilized iron nanoparticles from acid mine drainage and Rooibos tea for application as a Fenton-like catalyst
(American Chemical Society, 2022)Intensive mining activities generate toxic acid mine drainage (AMD) effluents containing a high concentration of metals, including iron. The chemical synthesis of iron nanoparticles from this waste could lead to further ... -
Inferring halo masses with graph neural networks
(Institute of Physics, 2022)Understanding the halo–galaxy connection is fundamental in order to improve our knowledge on the nature and properties of dark matter. In this work, we build a model that infers the mass of a halo given the positions, ... -
Fractions of Hoslundia opposita Vahl and hoslundin induced apoptosis in human cancer cells via mitochondrial-dependent reactive oxygen species (ROS) generation
(Elsevier, 2022)ancer remains one of the leading causalities of several morbidity and mortality with negative impact on global economy due to low workforce and management/treatment cost. A number of conventional therapies have been ... -
Zebrafish behavioral response to ivermectin: Insights into potential neurological risk
(Elsevier, 2022)Ivermectin is a well‐known and widely used anti‐parasitic drug. Recently, in vitro data suggest anti‐viral effi- cacy of the drug, albeit at much higher concentrations than currently approved. Despite warnings by ... -
Analysis of unmarried adolescents and modern contraceptives initiation in Nigeria: Evidence from 2018 NDHS
