Analysis of the early events in the interaction between Venturia inaequalis and the susceptible Golden Delicious apple (Malus x domestica Borkh.)
(University of the Western Cape, 2014)Apple (Malus x domestica) production in the Western Cape, South Africa, is one of the major contributors to the gross domestic product (GDP) of the region. The production of apples is affected by a number of diseases. One ... -
Analysis of the proteome of red and green leaf phenotypes of 'Bon Rouge' pear trees \trus communrls L. by 2-dimensional gel electrophoresis
(University of the Western Cape, 2007)The 'Bon Rouge' pear is a red pear cultivar derived from a rare, spontaneous bud mutation which occurred on the green pear 'William's Bon Chretien' (Bartlett). 'Bon Rouge' pear cultivar was observed to be reverting back ... -
Analysis, expression profiling and characterization of hsa-miR-5698 target genes as putative dynamic network biomarkers for prostate cancer: a combined in silico and molecular approach
(University of the Western Cape, 2019)2018, the International Agency for Research on Cancer (IARC) estimated that prostate cancer (PCa) was the second leading cause of death in males worldwide. The number of deaths are expected to raise by 50 % in the next ... -
Ancient Genes in Cancer Gene Expression?
(University of the Western Cape, 2004)Backsround: The Cancer/testis (CT) antigens are a division of germ cell specific genes not expressed in somatic cells, exceptions being placental cells and 20Vo - 4OVo of cancer types. The aptitude of CT antigens to elicit ... -
Antibacterial effects of biogenic silver nanoparticles synthesized using manihot esculenta (cassava) leaf aqueous extract
(University of the Western Cape, 2023)Antimicrobial resistance (AMR) is a growing global health concern that poses a serious threat to the health of humans, animals, and plants. The major public health problem of AMR is primarily caused by the incorrect use ... -
The antimicrobial activity of zinc oxide nanoparticles synthesized with plant extracts against Staphylococcus aureus
(University of the Western Cape, 2019)Nanoparticles using a green synthesis production method is of increasing interest for biomedical applications. Zinc oxide is currently used in medicinal and cosmetic formulations, and zinc oxide nanoparticles have potential ... -
Antimicrobial, anticancer and catalytic activities of green synthesized Avocado seed extract-gold nanoparticles
(University of the Western Cape, 2019)Nature through billions of years of trial and error has produced an immeasurable amount of natural systems like plants, birds and animals. The intelligence of nature is hidden in these natural systems and researchers are ... -
Aptamer selection against GFRa1 for its application in the prognosis of breast cancer
(University of the Western Cape, 2019)Breast cancer is the second most common cancer amongst South African women. Despite ongoing efforts to combat breast cancer, current prognostic and/or therapeutic monitoring methods are limited since very little improvement, ... -
The assessment of the bactericidal effect of green synthesized silver nanoparticles against a panel of infectious microorganisms
(University of the Western Cape, 2016)The emergence of multiple drug resistant microorganisms poses a major threat to human life. These microorganisms have made the currently used antibiotics ineffective and therefore continue to thrive. Therefore, there is a ... -
An assessment of the dietary intake of pregnant women in the West Coast / Winelands region, Western Cape Province: relation to low birth weight
(University of the Western Cape, 2008)This secondary analysis aimed to develop dietary scores to assess the dietary intake of pregnant women in the West Coast/ Winelands region and determine the association with LBW. Further to determine the association between ... -
Association between antioxidant activities and drought responses of two contrasting sugar beet genotypes
(University of the Western Cape, 2017)Sugar beet (Beta vulgaris L), which belongs to the Amaranthaceae family is a biennial crop widely used as a source of domestic sugar in the European countries, United States, China and Japan. However, in South Africa, sugar ... -
