A modern description of Crambionella stuhlmanni (Scyphozoa: Rhizostomeae) from St. Lucia Estuary, South Africa
(Cambridge University Press, 2011)A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species ... -
Modification of polyethylene terephthalate track etched membranes by planar magnetron sputtered Ti/TiO2 thin films
(Elsevier, 2021)This study investigates the surface modification of polyethylene terephthalate track-etched membranes by planar magnetron sputtering of titanium and titanium dioxide thin films to improve its hydrophilicity and photocatalytic ... -
Modulation of antioxidant enzyme activities and metabolites ratios by nitric oxide in short-term salt stressed soybean root nodules
(Elsevier, 2013)Several abiotic factors cause molecular damage to plants either directly or through the accumulation of reactive oxygen species such as hydrogen peroxide (H2O2). We investigated if application of nitric oxide (NO) donor ... -
Molecular adaptation mechanisms employed by ethanologenic bacteria in response to lignocellulose-derived inhibitory compounds
(Ivyspring, 2013)Current international interest in finding alternative sources of energy to the diminishing supplies of fossil fuels has encouraged research efforts in improving biofuel production technologies. In countries which lack ... -
Molecular and morphological analysis of subfamily Alooideae (Asphodelaceae) and the inclusion of Chortolirion in Aloe
(Botanischer Garten und Botanisches Museum, 2013)Asphodelaceae subfam. Alooideae (Asparagales) currently comprises five genera, four of which are endemic to southern Africa. Despite their importance in commercial horticulture the evolutionary relationships among the ... -
Molecular application of aptamers in the diagnosis and treatment of cancer and communicable diseases
(MDPI, 2018)Cancer and infectious diseases such as Ebola, HIV, tuberculosis, Zika, hepatitis, measles and human schistosomiasis are serious global health hazards. The increasing annual morbidities and mortalities of these diseases ... -
Molecular characterization of the 16S rRNA Gene of helicobacter fennelliae isolated from stools and blood cultures from paediatric patients in South Africa
(Hindawi, 2011)Forty strains of H. fennelliae collected from paediatric blood and stool samples over an 18 year period at a children's hospital in Cape Town, South Africa, were amplified by PCR of the 16S rRNA. Two distinct genotypes ... -
Molecular detection of tick-borne pathogen diversities in ticks from livestock and reptiles along the shores and adjacent islands of lake Victoria and lake Baringo, Kenya
(Frontiers Media, 2017)Tick-borne pathogens (TBPs) are responsible for some of the most serious emerging infectious diseases facing sub-Saharan Africa (SSA) and the rest of the world today (1, 2). In Kenya, TBPs (including viral diseases—arboviruses) ... -
Molecular dynamic simulations to investigate the structural impact of known drug resistance mutations on HIV-1C integrase-dolutegravir binding
(Public Library of Science, 2020)Resistance associated mutations (RAMs) threaten the long-term success of combination antiretroviral therapy (cART) outcomes for HIV-1 treatment. HIV-1 Integrase (IN) strand transfer inhibitors (INSTIs) have proven to be a ... -
Molecular evolution of key receptor genes in primates and non-human primates
(Science Publishing Group, 2014)African primates remain an unexplored source of information required to complete the origin and evolution of many human pathogens. Current studies have shown the importance of several receptor human genes implicated in ... -
Molecular genetic identification of skeletal remains of apartheid activists in South Africa
(Academic Journals, 2008)The Truth and Reconciliation Commission made significant progress in examining abuses committed during the apartheid era in South Africa. Despite information revealed by the commission, a large number of individuals ... -
Molecularly imprinted polypyrrole sensors for the detection of pyrene in aqueous solutions
(Springer Nature, 2021)Recently, electrochemical sensors have emerged as tools for polyaromatic hydrocarbons (PAH) detection that are cost-effective, easy to produce and use, highly selective and sensitive, and with good reproducibility. Polypyrrole ... -
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 ... -
Monoclonal Antibodies targeting the HR2 Domain and the region immediately upstream of the HR2 of the S Protein neutralize in Vitro Infection of Severe Acute Respiratory Syndrome Coronavirus
(American Society for Microbiology, 2006)We have previously shown that an Escherichia coli-expressed, denatured spike (S) protein fragment of the severe acute respiratory coronavirus, containing residues 1029 to 1192 which include the heptad repeat 2 (HR2) ... -
Montmorillonite modified by CNx supported Pt for methanol oxidation
(Elsevier, 2013)A composite support based on nature clay, i.e. montmorillonite (MMT), shows great promise as support materials for Pt electrocatalyst for the methanol oxidation reaction in fuel cell anodes. The reported composite support ... -
More on the nature of the variable star UNSW-V-760
(Oxford University Press, 2012)The results of two multicolour time-series photometric observing runs, separated by about two months, are presented. The same periodicities previously detected in photometry of UNSWV- 760 are still present, albeit at ... -
Morpho-physiological, biochemical, and genetic responses to salinity in medicago truncatula
