Proteomic identification and meta-analysis in salvia hispanica RNA-seq de novo assemblies
(2021)While proteomics has demonstrated its value for model organisms and for organisms with mature genome sequence annotations, proteomics has been of less value in nonmodel organisms that are unaccompanied by genome sequence ... -
Proteomic mechanisms of drug resistance in Candida cell membrane fractions
(International Association for Dental Research, 2014)INTRODUCTION: The African continent has the highest burden of HIV infection, accounting for approximately 65% of new infections globally. Oral candidiasis is a major cause of increased morbidity in HIV-infected individuals ... -
Proteomics analysis of the p.G849D variant in neurexin 2 alpha may reveal insight into Parkinson’s disease pathobiology
(Frontiers, 2022)Parkinson’s disease (PD), the fastest-growing neurological disorder globally, has a complex etiology. A previous study by our group identified the p.G849D variant in neurexin 2 (NRXN2), encoding the synaptic protein, ... -
Proteomics and metabolomics — Current and future perspectives in clinical andrology
(Blackwell Publishing Ltd, 2021)Proteomics and metabolomics are emerging as promising tools to investigate the molecular mechanisms associated with male infertility. Proteins and metabolites play a pivotal role in regulating the molecular pathways ... -
Proteomics of drug-resistant HIV-associated candidiasis
(University of the Western Cape, 2015)Candidiasis and HIV co-infection may cause increased patient morbidity and mortality due to oropharyngeal or systemic dissemination. Limited information exists on the prevalence, antifungal susceptibility profiles and drug ... -
Provenance and tectonic setting of the Paleozoic Tamatán Group, NE Mexico: Implications for the closure of the Rheic Ocean
(Elsevier, 2021)The Huizachal–Peregrina Anticlinorium in northeastern Mexico comprises a wide variety of Precambrian and Paleozoic basement units. In this work, Silurian-to-Permian unmetamorphosed siliciclastic successions (i.e., Cañón ... -
Provenance of metasedimentary rocks of the western Dom Feliciano Belt in Uruguay: Insights from U–Pb detrital zircon geochronology, Hf and Nd model ages, and geochemical data
(Elsevier, 2021)New isotopic and geochemical data for the Paleo- Meso- and Neoproterozoic metasedimentary cover of the southern Dom Feliciano Belt (Brasiliano/Pan-African) are presented and evaluated combined with published information. ... -
Provision of syndromic treatment of sexually transmitted infections by community pharmacists: a potentially underutilized HIV prevention strategy
(Lippincott, Williams & Wilkins, 2003)Background: Sexually transmitted infections (STIs) are known risk factors for HIV infection. Goal: The goal of this study was to assess the current and potential future role that community pharmacists in Western Cape, South ... -
Proximate determinants of fertility in Ethiopia: comparative analysis of the 2005 and 2011 DHS
(SAGE Publications, 2017)Fertility is one of the elements in population dynamics that makes a significant contribution towards changing population size and structure over time. In Ethiopia, for the last 10 years the total fertility rate (TFR) has ... -
Pseudocapacitive effects of multi-walled carbon nanotubes-functionalised spinel copper manganese oxide
(MDPI, 2022)Spinel copper manganese oxide nanoparticles combined with acid-treated multi-walled carbon nanotubes (CuMn2O4/MWCNTs) were used in the development of electrodes for pseudocapacitor applications. The CuMn2O4/MWCNTs ... -
PSRJ1910–5959A: A rare gravitational laboratory for testing white dwarf models
(EDP Sciences, 2023)Context. PSR J1910-5959A is a binary millisecond pulsar in a 0.837 day circular orbit around a helium white dwarf (HeWD) companion. The position of this pulsar is 6.3 arcmin (∼74 core radii) away from the optical centre ... -
