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
(MDPI, 2021)We used an integrated morpho-physiological, biochemical, and genetic approach to investigate the salt responses of four lines (TN1.11, TN6.18, JA17, and A10) of Medicago truncatula. Results showed that TN1.11 exhibited a ... -
Morphological and physiological responses of Calobota sericea plants subjected to water limitation and subsequent rewatering
(Taylor and Francis Group, 2021)Calobota sericea is a native legume of South Africa, confined to the water-limited rangelands, and it has recently been prioritised for additional characterisation regarding its pasture potential. In this study, we examined ... -
Morphometric and structural analysis of Florida manateespermatozoa
(Wiley, 2022)Sperm characteristics, such as sperm morphology and sperm morphometry areimportant in assessing sperm quality. This is especially important for the man-agement and conservation of endangered and exotic species, like the ... -
Moving ICTD research beyond bungee jumping: practical case studies and recommendations
(Institute of Electrical and Electronics Engineers, 2016)The global spread of Internet and mobile communications has been accompanied by a growing interest in how information and communication technologies (ICTs) can contribute to social and economic development. There are a ... -
Mufasa: The assembly of the red sequence
(Oxford University Press, 2017)We examine the growth and evolution of quenched galaxies in the Mufasa cosmo- logical hydrodynamic simulations that include an evolving halo mass-based quench- ing prescription, with galaxy colours computed accounting ... -
MUFASA: The strength and evolution of galaxy conformity in various tracers
(Oxford University Press, 2017)We investigate galaxy conformity using the Mufasa cosmological hydrodynamical simulation. We show a bimodal distribution in galaxy colour with radius, albeit with too many low-mass quenched satellite galaxies compared ... -
