Re-engineering of South Africa’s primary health care system: where is the pharmacist?
(South African Academy of Family Physicians, 2016)South Africa’s transition towards a district-based health system (DHS) aims to offer health promotion and prevention services at community level, through re-engineered primary health care (PHC) services. Along with pharmacy ... -
Reactive oxygen species and male reproductive hormones
(BMC, 2018)Reports of the increasing incidence of male infertility paired with decreasing semen quality have triggered studies on the effects of lifestyle and environmental factors on the male reproductive potential. There are ... -

A real time processing system for big data in astronomy: Applications to Hera
(Elsevier, 2021)As current- and next-generation astronomical instruments come online, they will generate an unprecedented deluge of data. Analyzing these data in real time presents unique conceptual and computational challenges, and their ... -
Real-time assessment of Candida biofilm disruption by Galenia africana
(2022-05-25)Candida species often cause opportunistic infections in immunocompromised patients and are able to form highly structured biofilms that protect the yeast cells from the external environment and the action of antimicrobials. ... -
Real-time assessment of Candida biofilm formation
(Elsevier, 2021-09)Background: Candida infections are responsible for increased morbidity and mortality in immunocompromised patients, particularly when the Candida biofilm is composed of drug-resistant species. Although the biofilm formation ... -
Real-time assessment of interspecies candida biofilm formation
(Bentham Open, 2022-12-30)Background: Candida infections are responsible for increased morbidity and mortality in immunocompromised patients, with Candida having the ability to form highly structured biofilms that protect them from the external ... -
Real-time gesture recognition using eigenvectors
(2009)This paper discusses an implementation for gesture recognition using eigenvectors under controlled conditions. This application of eigenvector recognition is trained on a set of defined hand images. Training images are ... -
Reasons for missed appointments linked to a public-sector intervention targeting patients with stable chronic conditions in South Africa: results from in-depth interviews and a retrospective review of medical records
(BioMed Central, 2017)BACKGROUND Missed appointments serve as a key indicator for adherence to therapy and as such, identifying patient reasons for this inconsistency could assist in developing programmes to improve health outcomes. In this ... -
Recalibrating the Wide-field Infrared Survey Explorer (WISE) W4 Filter
(Cambridge University Press, 2014)We present a revised effective wavelength and photometric calibration for the Wide-field Infrared Survey Explorer W4 band, including tests of empirically motivated modifications to its pre-launch laboratory-measured ... -
Recent advancements in the breeding of sorghum crop: current status and future strategies for marker-assisted breeding
(Frontiers, 2023)Sorghum is emerging as a model crop for functional genetics and genomics of tropical grasses with abundant uses, including food, feed, and fuel, among others. It is currently the fifth most significant primary cereal crop. ... -
Recent advances in the detection of interferon‑gamma as a TB biomarker
(Springer, 2021)Tuberculosis (TB) is one of the main infectious diseases worldwide and accounts for many deaths. It is caused by Mycobacterium tuberculosis usually afecting the lungs of patients. Early diagnosis and treatment are essential ... -
Recent Advances in the Development of Antimicrobial and Antifouling Biocompatible Materials for Dental Applications
(MDPI, 2021)The risk of secondary bacterial infections resulting from dental procedures has driven the design of antimicrobial and antifouling dental materials to curb pathogenic microbial growth, biofilm formation and subsequent ... -
Reconstructing drainage pathways in the North Atlantic during the Triassic utilizing heavy minerals, mineral chemistry, and detrital zircon geochronology
(Geological Society of America, 2021)In this study, single-grain mineral geochemistry, detrital zircon geochronology, and conventional heavy-mineral analysis are used to elucidate sediment transport pathways that existed in the North Atlantic region during ... -
Reconstructing the deep-branching relationships of the papilionoid legumes
(Elsevier, 2013)Resolving the phylogenetic relationships of the deep nodes of papilionoid legumes (Papilionoideae) is essential to understanding the evolutionary history and diversification of this economically and ecologically important ... -
Reconstruction of dark energy and expansion dynamics using Gaussian processes
(IOP Publishing, 2012)An important issue in cosmology is reconstructing the effective dark energy equation of state directly from observations. With few physically motivated models, future dark energy studies cannot only be based on constraining ... -
