Infrared luminosity functions and dust mass functions in the EAGLE simulation
(Oxford University Press, 2020)We present infrared luminosity functions and dust mass functions for the EAGLE cosmological simulation, based on synthetic multiwavelength observations generated with the SKIRT radiative transfer code. In the local Universe, ... -
The infrared-radio correlation of star-forming galaxies is strongly M∗-dependent but nearly redshift-invariant since z ∼4
(EDP Sciences, 2021)Over the past decade, several works have used the ratio between total (rest 8-1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (qIR), often referred to as the infrared-radio correlation (IRRC), ... -

(Springer, 2023)This contribution reports on the development of two versatile and efcient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition potential ... -
Inhibiting CDK6 activity by quercetin is an attractive strategy for cancer therapy
(American Chemical Society, 2020)Cyclin-dependent kinase 6 (CDK6) is a potential drug target that plays an important role in the progression of different types of cancers. We performed in silico and in vitro screening of different natural compounds and ... -
Inhibition of bacteria associated with wound infection by biocompatible green synthesized gold nanoparticles from South African plant extracts
(MDPI, 2017)Unlike conventional physical and chemical methods, the biogenic synthesis of gold nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible GNPs that can be utilized in various biomedical ... -
Inhibition of HIV-1 enzymes, antioxidant and anti-inflammatory activities of Plectranthus barbatus
(Elsevier, 213)Ethnopharmacological relevance: Plectranthus barbatus is widely used in African countries as an herbal remedy to manage HIV/AIDS and related conditions. Aim of the study: To investigate the HIV-1 inhibitory, anti-inflammatory ... -
Inhibition of NOS- like activity in maize alters the expression of genes involved in H2O2 scavenging and glycine betaine biosynthesis
(Nature Publishing Group, 2018)Nitric oxide synthase-like activity contributes to the production of nitric oxide in plants, which controls plant responses to stress. This study investigates if changes in ascorbate peroxidase enzymatic activity and ... -
Inhibition of oxidative stress and skin aging-related enzymes by prenylated chalcones and other flavonoids from helichrysum teretifolium
(MDPI, 2015)Ten flavonoid-related structures viz. heliteretifolin (1), isoxanthohumol (2), 2',4',6'-trihydroxy-3'-prenylchalcone (3), isoglabranin (4), glabranin (5), 7-methoxyisoglabranin (6), quercetin (7), 4'-methoxyquercetin ... -
Inhibitory potential of repurposed drugs against the SARS-CoV-2 main protease: A computational-aided approach
(Taylor and Francis, 2020)The exponential increase in cases and mortality of coronavirus disease (COVID-19) has called for a need to develop drugs to treat this infection. Using in silico and molecular docking approaches, this study investigated ... -
Initial evaluation of the care and rehabilitation success of Cape Cormorants Phalacrocorax capensis rescued from Robben and Jutten islands, South Africa, in January 2021
(Taylor and Francis Group, 2023)The population of the endangered Cape Cormorant Phalacrocorax capensis more than halved over the last three decades (BirdLife International 2018a). In January 2021, nearly 2 000 Cape Cormorant chicks were ... -
Inorganic ions in leonotis leonurus extract do not explain changes in isolated Wistar rat heart function
(Open Access Science Research Publisher, 2011)Leonotis leonurus (L. leonurus) R. Br (Lamiaceae) is used by healers in South Africa. The present study was conducted to determine if the L. leonurus effect on isolated rat heart is due to ionic changes in the perfusion fluid. -
