Pathways and gateways of freshwater invasions in Europe
(Regional Euro-Asian Biological Invasions Centre, 2015)Taking into account the continuous increase in freshwater introductions, and to support the recent European legislation on invasive alien species, the identification of priority pathways and gateways of introductions is ... -
GR dimerization and the impact of GR dimerization on GR protein stability and half-life
(Frontiers Media, 2019-07-17)Pharmacologically, glucocorticoids, which mediate their effects via the glucocorticoid receptor (GR), are a most effective therapy for inflammatory diseases despite the fact that chronic use causes side-effects and ... -
Rooibos (Aspalathus linearis) and honeybush (Cyclopia spp.) : from bush teas to potential therapy for cardiovascular disease
(IntechOpen, 2019)Cardiovascular disease (CVD) is a leading cause of worldwide deaths. A number of risk factors for cardiovascular disease as well as type 2 diabetes and stroke present as the metabolic syndrome. Metabolic risk factors include ... -
Estimation of groundwater recharge via percolation outputs from a rainfall / runoff model for the Verlorenvlei estuarine system, West coast, South Africa
(Elsevier, 2018)Wetlands are conservation priorities worldwide, due to their high biodiversity and productivity, but are under threat from agricultural and climate change stresses. To improve the water management practices and resource ... -
Distributive rainfall–runoff modelling to understand runoff-to-baseflow proportioning and its impact on the determination of reserve requirements of the Verlorenvlei Estuarine lake, West coast, South Africa
(European Geosciences Union, 2019-06-24)River systems that support high biodiversity profiles are conservation priorities worldwide. Understanding river ecosystem thresholds to low-flow conditions is important for the conservation of these systems. While climatic ... -
Knoxdaviesia proteae is not the only Knoxdaviesia-symbiont of Protea repens
(International Mycological Association, 2015-11-10)Two polyphyletic genera of ophiostomatoid fungi are symbionts of Proteaceae in southern Africa. One of these, Knoxdaviesia, includes two closely related species, K. proteae and K. capensis, that have overlapping geographical ... -
A phylogenetic revision of Penicillium sect. Exilicaulis, including nine new species from fynbos in South Africa
(International Mycological Association, 2016-06-01)A survey of the fynbos biome in South Africa resulted in the isolation of 61 Penicillium species from Protea repens infructescences, air, and soil samples. Fourteen of these belong to Penicillium sect. Exilicaulis and ... -
Inflammatory cytokines in type 2 diabetes mellitus as facilitators of hypercoagulation and abnormal clot formation
(BMC (part of Springer Nature), 2019-06-04)Background: The global burden of type 2 diabetes mellitus (T2DM), together with the presence of cardiovascular risk in this population, is reaching pandemic levels. A prominent feature of T2DM is chronic and systemic ... -
Dietary impact on neuronal autophagy control and brain health
(IntechOpen, 2019)Autophagy is the major intracellular system which is critical for the removal of harmful protein aggregates and malfunctioning organelles. Dysfunctional autophagy is associated with a multitude of human diseases, such ... -
Links between the phytoplankton community composition and trace metal distribution in summer surface waters of the Atlantic Southern Ocean
(Frontiers Media, 2019-06-06)This study assessed changes in the phytoplankton community related to macronutrient and bioactive trace metal distribution in surface waters of the Atlantic sector of the Southern Ocean, between Cape Town and Antarctica ... -
Iron-rich nanoparticles in natural aquatic environments
(MDPI, 2019-05-11)Naturally-occurring iron nanoparticles constitute a quantitatively-important and biogeochemically-active component of the broader Earth ecosystem. Yet detailed insights into their chemical speciation is sparse compared ... -
DNA vaccines against mycoplasma elicit humoral immune responses in ostriches
(Frontiers Media, 2019-05-14)In ostriches, the population densities resulting from intensive rearing increases susceptibility to pathogens such as mycoplasmas. In addition to good management practices, vaccination offers an attractive alternative ... -
Molecular evidence for cryptic species in the common slug eating snake Duberria lutrix lutrix (Squamata, Lamprophiidae) from South Africa
(Pensoft, 2019-04-15)We examined the impact of climatic fluctuations on the phylogeographic structure of the common slug eating snake (Duberria lutrix lutrix) throughout its distribution in South Africa. The evolutionary history within the ... -
Environmental temperature alters the overall digestive energetics and differentially affects dietary protein and lipid use in a lizard
(The Company of Biologists, 2019)Processing food (e.g. ingestion, digestion, assimilation) requires energy referred to as specific dynamic action (SDA) and is at least partially fuelled by oxidation of the nutrients (e.g. proteins and lipids) within ... -

Chemoresistance : intricate interplay between breast tumor cells and adipocytes in the tumor microenvironment
(Frontiers Media, 2018-12-11)Excess adipose tissue is a hallmark of an overweight and/or obese state as well as a primary risk factor for breast cancer development and progression. In an overweight/obese state adipose tissue becomes dysfunctional due ... -
Learning dynamics of linear denoising autoencoders
(PMLR, 2018)Denoising autoencoders (DAEs) have proven useful for unsupervised representation learning, but a thorough theoretical understanding is still lacking of how the input noise influences learning. Here we develop theory ... -
C-reactive protein is elevated only in high creatine kinase responders to muscle damaging exercise
(Frontiers Media, 2017-02-11)The purpose of this study was to investigate if exertional rhabdomyolysis induced by an acute bout of plyometric exercise in untrained individuals was associated with histological characteristics of skeletal muscle, creatine ... -
Role of myrmekites and associated deformation fabrics in controlling development of granitic mylonites in the Pofadder Shear Zone, Southern Namibia
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The predominantly granitic Pofadder Shear Zone (PSZ) of southern Namibia is a crustal-scale dextral shear zone exhumed from the brittle-ductile transition. A variably deformed megacrystic granite with ... -
Euler Classes and Frobenius Algebras
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT : This thesis investigates the relationship between the handle element of the De Rham cohomology algebra of a compact oriented smooth manifold, thought of as a Frobenius algebra, and the Euler class of ...
