The air quality perceptions of the residents of Bayview, Mossel Bay
(NACA, 2014)Background: In developing countries, it often occurs that little attention is given to air pollution emissions due to a lack of proper town planning, household combustion processes, energy production and the continuous ... -
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 ... -
Polymer-based protein delivery systems for loco-regional administration
(Taylor and Francis Group, 2021)With the advent of recombinant technology, a wide variety of biocompatible therapeutic proteins can be produced with relative ease. These proteins are formulated and subsequently administered in patients to treat various ... -
Synthesis of 4-oxatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione derivatives as lead scaffolds for neuroprotective agents
(ARKAT USA, 2020)Neurodegenerative disorders are characterised by progressive loss of neuronal functions. Of the proposed mechanisms, excitotoxicity, mediated by prolonged glutamate activation and calcium overload, is prominent. NGP1-01, ... -
Pharmaceutical co-crystal: An alternative strategy for enhanced physicochemical properties and drug synergy
(Wiley Open Access, 2020)A growing number of co-crystals in the literature are proof of how significant the co-crystallization concept has become. Co-crystallization enhances physicochemical properties through the formation of intermolecular ... -
Evaluation of Antibacterial Activity of Bryopsis pennata and Chaetomorpha antennina against Multidrug Resistant Morganella morganii and Salmonella species Isolated from Healthy Individuals
(International Journal for Pharmaceutical Research Scholars, 2017)The problem of antibiotic resistance is fast becoming a pandemic which has necessitated the need for new drugs discovery. This study was carried out to screen two green algal species- Bryopsis pennata and Chaetomorpha ... -
Implementing value chain analysis to investigate drivers and sustainability of Cape Town's informal economy of wild-harvested traditional medicine
(Routledge, 2015)Despite a highly visible presence, policy-maker knowledge of the drivers and participants in the informal economy of wild-harvested medicinal plants in Cape Town remains limited. To illuminate the workings of this local ... -
An invasive alien Proteaceae lures some, but not all nectar-feeding bird pollinators away from native Proteaceae in South African fynbos
(Plant Biology, 2021)Invasive alien plants often influence pollinator visitation to native plants when sharing pollinator guilds. It is of conservation concern when the invasive alien plant is characterized by floral resources that attract ... -
Large Scale Screening of Southern African Plant Extracts for the Green Synthesis of Gold Nanoparticles Using Microtitre-Plate Method
(Molecules, 2016-11)The preparation of gold nanoparticles (AuNPs) involves a variety of chemical and physical methods. These methods use toxic and environmentally harmful chemicals. Consequently, the synthesis of AuNPs using green chemistry ... -
The effectiveness of using text and pictograms on oral rehydration, dry-mixture sachet labels
(AOSIS, 2021)Medication labels are often the only information available to patients after obtaining medication from a healthcare practitioner. Pictograms are graphic symbols that have shown to increase understanding of medicine use ... -
