Repurposing based identification of novel inhibitors against mmps5-mmpl5 efflux pump of Mycobacterium smegmatis: A combined in silico and in vitro study
(MDPI, 2022)In the current era of a pandemic, infections of COVID-19 and Tuberculosis (TB) enhance the detrimental effects of both diseases in suffering individuals. The resistance mechanisms evolving in Mycobacterium tuberculosis ... -
Research and development of hydrogen carrier based solutions for hydrogen compression and storage
(IOP Publishing, 2022)Industrial and public interest in hydrogen technologies has risen strongly recently, as hydrogen is the ideal means for medium to long term energy storage, transport and usage in combination with renewable and green ... -
Resilience and sustainability of the water sector during the Covid-19 pandemic
(MDPI, 2022)The COVID-19 pandemic brought unprecedented socio-economic changes, ushering in a “new (ab)normal” way of living and human interaction. The water sector was not spared from the effects of the pandemic, a period in which ... -
Response of soybean nodules to exogenously applied caffeic acid during NaCl-induced salinity
(Elsevier, 2015)affeic acid acts as an antioxidant to scavenge reactive oxygen species, but its influence on plant responses to abi- otic stresses is only partially understood. Here, we investigated the influence of exogenously applied ... -
Response to letter to the Editor: The therapeutic strategy of drug re-positioning to induce autophagic cell death in brain malignancy
(Springer Nature, 2021)We thank Dr Yoshida for his valuable comments and interest in our study which describes the anti-cancer activity of DS00329, a novel derivative of the anti-psychotic drug phenothiazine, in glioblastoma multiforme (GBM) ... -
The rest-frame UV luminosity function at z 4: A significant contribution of AGNs to the bright end of the galaxy population
(Oxford University Press, 2020)We measure the rest-frame ultraviolet (UV) luminosity function (LF) at z ∼ 4 self-consistently over a wide range in absolute magnitude (−27 ≲ MUV ≲ −20). The LF is measured with 46 904 sources selected using a photometric ... -
A retrospective analysis of applications for registration of generic medicines processed by the medicines control authority of Zimbabwe
(Springer, 2023)Many applications for registration of medicines are rejected because applicants fail to submit or resolve critical deficiencies in the quality, efficacy, and safety of the medicines. The study aimed to establish approval ... -
A retrospective descriptive investigation of adult patients receiving third-line antiretroviral therapy in the North West province, South Africa
(Makerere University, 2020)Greater access and prolonged exposure to ART may inevitably lead to more treatment failure and increase the need for third-line ART (TLART) in a resource-limited setting. Objective: To describe characteristics and resistance ... -
Revealing the cold dust in low-metallicity environments: I. Photometry analysis of the Dwarf Galaxy Survey with Herschel
(EDP Sciences, 2013)Context. We present new photometric data from our Herschel Guaranteed Time Key Programme, the Dwarf Galaxy Survey (DGS), dedicated to the observation of the gas and dust in low-metallicity environments. A total of 48 ... -
Review and re-analysis of domain-specific 16S primers
(Elsevier, 2003)The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable microorganisms in virtually any environmental source and has thus been used extensively in the assessment of environmental microbial diversity. ... -
A review of combined advanced oxidation technologies for the removal of organic pollutants from water
(Springer Verlag, 2014)Water pollution through natural and anthropogenic activities has become a global problem causing short-and long-term impact on human and ecosystems. Substantial quantity of individual or mixtures of organic pollutants enter ... -
Review of in-situ and remote sensing-based indices and their applicability for integrated drought monitoring in South Africa
(MDPI, 2023)The devastating socioeconomic impacts of recent droughts have intensified the need for improved drought monitoring in South Africa (SA). This study has shown that not all indices can be universally applicable at all ... -
A review of pharmaceuticals and endocrine-disrupting compounds: sources, effects, removal, and detections
(Springer, 2013)There are growing concerns about the increasing trends of emerging micropollutants in the environment due to their potential negative impacts on natural ecosystems and humans. This has attracted attention from both ... -
