Effects of graphene oxide nanoparticles on the immune system biomarkers produced by RAW 264.7
(University of the Western Cape, 2019)Graphene oxide (GO) is a single carbon layer, oxygen bearing graphene derivative, containing hydroxyl and carboxyl groups. Graphene oxide nanoparticles (GONPs) are promising nanomaterials for a variety of applications such ... -
The effects of green tea, green rooibos and their major flavonoids (EGCG and aspalathin) on testicular cell health in vitro
(University of Western Cape, 2021)The testes play a central role in the male reproductive system, as they represent the sites of male sex steroidogenesis and of spermatogenesis. Leydig cells, located at the testicular interstitium, produce predominantly ... -
Effects of green, black and rooibos tea, coffee and buchu on testosterone production by mouse testicular cultures
(University of the Western Cape, 2013)Modulation of the male reproductive system occurs as a result of exposure to endocrine disrupting compounds (EDCs) in different life stages. The effects of EDCs on the male reproductive system include infertility, decreased ... -
The effects of hypoxis hemerocallidea on blood glucose levels in rats with Type 2 diabetes
(University of the Western Cape, 2015)About 180 million people have been estimated to suffer from type 2 diabetes (T2DM) in 2006 and the annual death rate due to this disease was 3 million by that time. More than 400 medicinal plants used for the treatment ... -
Effects of land-cover - land-use on water quality within the kuils - Eerste River Catchment
(University of Western Cape, 2012)The most significant human impacts on the hydrological system are due to land-use change. The conversion of land to agricultural, mining, industrial, or residential uses significantly alters the hydrological characteristics ... -
Effects of Leonotis leonorus aqueous extract on the isolated perfused rat heart
(University of the Western Cape, 2007)An aqueous extract prepared from the leaves and smaller stems of Leonotis leonorus was used to investigate the potential effects on certain cardiovascular parameters such as left ventricular systonic pressure, end-diastolic ... -
Effects of Leonotis leonurus aqueous extract on the isolated perfused rat heart
(University of the Western Cape, 2007)An aqueous extract prepared from the leaves and smaller stems of Leonotis leonurus was used to investigate the potential effects on certain cardiovascular parameters, such as left ventricular systolic pressure, end-diastolic ... -
Effects of Libyan traditional plants on the reproductive system of male and female rats
(University of the Western cape, 2015)In different parts of the world, medicinal plants have demonstrated a lot of health benefits to mankind and remains an important source for the discovery of new bio-active compounds. Libya is a typical example of a country ... -

The effects of maternal diets, varying in fat content, on proximal hepatic and skeletal muscle insulin signalling in neonatal wistar rat offspring
(University of the Western Cape, 2013)The incidence of type 2 diabetes (T2D) is persistently increasing globally. T2D is associated with pancreatic β cell dysfunction and insulin resistance in peripheral tissues such as the liver and skeletal muscle. Skeletal ... -
The effects of maternal nicotine exposure during pregnancy or lactation on hypertension of the offspring
(University of the Western Cape, 2016)Blood pressure and heart rate is known to increase during smoking. These effects are specifically associated with nicotine while the other components of tobacco smoke seem to be of minor importance. It is becoming increasingly ... -
The effects of minerals on reservoir properties in block 3A and 2C, within the orange basin, South Africa.
(University of the Western Cape, 2018)The reservoir quality of the Orange Basin, offshore South Africa is known to be immensely impaired by the presence of authigenic minerals. The collective effects of burial, bioturbation, compaction and chemical reactions ... -
The effects of nanomaterials, in the presence and absence of serum proteins, on testicular cell metabolic processes and steroidogenesis
(University of the Western Cape, 2014)The aim of this study is to be the first to ascertain the effects of silver nanoparticles on testosterone production. The Ag NPs used for this study have the following characteristics; purity ≥ 99.5%; 66.7 % of particles ... -
Effects of nitric oxide and hydrogen peroxide on antioxidant enzyme activity in zea mays subjected to drought
(University of Western Cape, 2021)Agricultural practices are significantly affected by drought. Drought is one of the most important plant stresses, causing several physiological, morphological, biochemical, and molecular changes in plants. Drought stress ... -
Effects of nitric oxide on novel soybean cystatin gene expression under salt stress in soybean
(University of the Western Cape, 2012)Nitric oxide (NO) has been shown to orchestrate multiple defense responses to both abiotic and biotic stress. Importantly, elevation of nitric oxide content in plants by using nitric oxide generating compounds has been ... -
The effects of nitric oxide on soybean superoxide dismutase activity during osmotic stress
(University of the Western Cape, 2012)Nitric oxide (NO) is a signaling molecule involved in mediating plant responses to various biotic and abiotic stresses. Major abiotic stresses (drought, salinity, cold) induce common cellular responses, causing osmotic ... -
