Environmental contaminants and male infertility: Effects and mechanisms
(Blackwell Publishing Ltd, 2021)The escalating prevalence of male infertility and decreasing trend in sperm quality have been correlated with rapid industrialisation and the associated discharge of an excess of synthetic substances into the environment. ... -
Environmental flow assessments are not realizing their potential as an aid to basin planning
(Frontiers Media, 2018)Multiple planned dams in developing countries, mostly for hydropower, are threatening some of the world’s great river systems. Concern over their social and environmental impacts has led to hydropower being excluded from ... -
Environmental response and ph tolerance of induced co2 in ulva rigida c.agardh, 1823(Chlorophyta) under controlled conditions
(PAS FORUM, 2022)The increase in integrated multitrophic aquaculture (IMTA), where seaweed (particularly Ulva rigidaC.Agardh, 1823) is used as a feedstock and a wastewater scrubber in South African IMTA systems, has necessitated research ... -
Environmental responses of jellyfish polyps as drivers of medusa populations off the coast of Namibia
(National Inquiry Services Centre, 2018)Jellyfish populations in the southeastern Atlantic off the coast of Namibia have increased subsequent to the decline of small pelagic fisheries at the end of the 1960s, although the environment there has also become warmer ... -
Enzymatic and proteomic exploration into the inhibitory activities of lemongrass and lemon essential oils against Botrytis cinerea (causative pathogen of gray mold)
(Frontiers Media, 2023)Essential oils (EOs) have been demonstrated as efficacious against B. cinerea. However, the underpinning enzymatic and proteomic mechanism for these inhibitory effects is not entirely clear. Thus, this study examined the ... -
Enzymatic and proteomic exploration into the inhibitory activities of lemongrass and lemon essential oils against botrytis cinerea (causative pathogen of gray mold)
(Front. Microbiol, 2023)Introduction: Essential oils (EOs) have been demonstrated as efficacious against B. cinerea. However, the underpinning enzymatic and proteomic mechanism for these inhibitory effects is not entirely clear. Methods: Thus, ... -
Enzymatic detoxification of the fumonisin mycotoxins during dry milling of maize
(Elsevier, 2021)Fumonisin esterase FumD (EC 3.1.1.87), FUMzyme® (BIOMIN, Austria), effectively detoxifies fumonisin B mycotoxins (FB) by hydrolysis and removal of the tricarballylic acid groups. The current study evaluated FumD detoxification ... -
EPIC 216747137: a new HW Vir eclipsing binary with a massive sdOB primary and a low-mass M-dwarf companion
(Ithaca, 2020)EPIC 216747137 is a new HW Virginis system discovered by the Kepler spacecraft during its K2 ‘second life’. Like the other HW Vir systems, EPIC 216747137 is a post-common-envelope eclipsing binary consisting of a hot ... -
Epidemiological analysis of spatially misaligned data: a case of highly pathogenic avian influenza virus outbreak in Nigeria
(Cambridge University Press, 2013)This research is focused on the epidemiological analysis of the transmission of the highly pathogenic avian influenza (HPAI) H5N1 virus outbreak in Nigeria. The data included 145 outbreaks together with the locations of ... -
Epidemiology and outcomes of Clostridium difficile infection among hospitalised patients: results of a multicentre retrospective study in South Africa
(BMJ Publishing Group, 2018)INTRODUCTION Limited data exist on Clostridium difficile infection (CDI) in low-resource settings and settings with high prevalence of HIV. We aimed to determine baseline CDI patient characteristics and management and ... -
Epidemiology, clinical characteristics and severity of gradual onset injuries in recreational road cyclists: A cross-sectional study in 21,824 cyclists - SAFER XIII
(Elsevier, 2020)Objectives: Prevalence, clinical characteristics and severity of gradual onset injuries (GOIs) in cyclists are poorly documented. We determine the prevalence, anatomical regions/sites affected and severity of GOIs among ... -
Epididymal contribution to male infertility: An overlooked problem
(Blackwell Publishing Ltd, 2021)The diagnosis and treatment of male infertility, excluding assisted conception, are limited because of, but not limited to, poor understanding of sperm post-testicular development and storage. Many may think that sperm ... -
Epizootic ulcerative syndrome – first report of evidence from South Africa's largest and premier conservation area, the Kruger National Park
(ScienceDirect, 2019)This study reports on the first evidence of genomic material of the causative agent for epizootic ulcerative syndrome (EUS), Aphanomyces invadans, from fish in the Limpopo River system and the Kruger National Park, South ... -
Erratum to: Post-orogenic shoshonitic magmas of the Yzerfontein pluton, South Africa: the 'smoking gun' of mantle melting and crustal growth during Cape granite genesis?
(Springer Verlag, 2017)The published version of the original paper contained a Sr isotope analysis of Hornblende-pyroxene quartz monzodiorite sample H25, from the shoshonitic part of the Cambrian Yzerfontein pluton on the West Coast in South ... -
Erratum: The frequency of very young galaxies in the local Universe: II. The view from SDSS spectra
(Oxford University Press, 2020)Only a handful of galaxies in the local Universe appear to be very young. We estimate the fraction of very young galaxies (VYGs), defined as those with more than half their stellar masses formed within the last Gyr. We ... -
Essential metal and metalloid elements in the Philippi Horticultural area, and their uptake into selected vegetable crops
(Taylor & Francis, 2018)This study evaluated Co, Cr, Mn, Ni, Se, Sn and V status in the soils of the PHA, as well as the vegetables produced on these soils. We also determined the agronomic sources of these elements to the soils in the PHA. ... -
