In vitro acetylcholinesterase inhibitory activity and chemical composition of the dichloromethane extracts of the leaves and inflorescences of the tumbleweed, Trachyandra laxa (N.E.Br.) Oberm. var. rigida (Suesseng.) Roessl
(South African Journal of Botany, 2022)
Trachyandra laxa, which belongs to the family Asphodelaceae, is a poisonous geophyte, often consumed by
livestock, particularly when pastures are poor. Ingestion of T. laxa by livestock causes paresis and paralysis of
the ...
Superhorizon perturbations: A possible explanation of the hubble–lemaître tension and the large-scale anisotropy of the universe
(IOP Publishing, 2022)
Current cosmological observations point to a serious discrepancy between the observed Hubble parameter obtained
using direct versus cosmic microwave background radiation measurements. Besides this so-called Hubble–
Lemaî

Marburg virus disease outbreak amidst COVID-19 in the Republic of Guinea: A point of contention for the fragile health system?
(Elsevier, 2022)
In August 2021, the Marburg virus disease (MVD) outbreak was confirmed amid the coronavirus disease 2019
(COVID-19) pandemic in the Republic of Guinea. This is the first time it is detected in Guinea and West Africa.
Marburg ...
The Role of Cytoskeletal Proteins in the Formation of a Functional In Vitro Blood-Brain Barrier Model
(MDPI, 2022)
The brain capillary endothelium is highly regulatory, maintaining the chemical stability of the brain’s microenvironment. The role of cytoskeletal proteins in tethering nanotubules (TENTs) during barrier-genesis was ...
A stochastic population model of cholera disease
(American Institute of Mathematical Sciences, 2022-02)
A cholera population model with stochastic transmission and stochasticity on the environmental reservoir of the cholera bacteria is presented. It is shown that solutions are well-behaved. In comparison with the underlying ...
Leveraging Google Earth engine platform to characterize and map small seasonal wetlands in the semi-arid environments of South Africa
(Elsevier, 2022)
Although significant scientific research strides have been made in mapping the spatial extents and
ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is ...
Common defciencies found in generic Finished Pharmaceutical Product (FPP) applications submitted for registration to the South African Health Products Regulatory Authority (SAHPRA)
(Springer Nature, 2022)
The aim of the study was to investigate the common defciencies observed in the Finished Pharmaceutical Product (FPP) section of generic product applications submitted to SAHPRA. The study was conducted
retrospectively ...
The MeerKAT Galaxy Cluster Legacy Survey: Survey overview and highlights
(University of the Western Cape, 2022)
MeerKAT’s large number (64) of 13.5 m diameter antennas, spanning 8 km with a densely packed 1 km core, create a powerful instrument for wide-area surveys, with high sensitivity over a wide range of angular scales. The ...
The Copernican principle in light of the latest cosmological data
(University of the Western Cape, 2022)
We pursue a program to confront observations with inhomogeneous extensions of the FLRW metric. The main idea is to test the Copernican principle (CP) rather than assuming it a priori. We consider the CDM model endowed with ...
A deep radio view of the evolution of the cosmic star formation rate density from a stellar-mass-selected sample in VLA-COSMOS
(Royal Astronomical Society, 2022)
We present the 1.4 GHz radio luminosity functions (RLFs) of galaxies in the Cosmic Evolution Survey (COSMOS) field, measured above and below the 5σ detection threshold, using a Bayesian model-fitting technique. The radio ...
