Devina Harry Kader Asmal Fellowship
The UFS’ Devina Harry was accepted into the Kader Asmal Fellowship Programme.

The UFS’ own Devina Harry is set to travel to Ireland in September 2020 to begin a year-long Fellowship Programme for a Master of Business. As one of 20 students selected from the African continent, Devina was recently accepted into the Kader Asmal Fellowship Programme, which affords her the opportunity to study in Ireland during the 2020/21 academic year.

A research assistant in the Department of Business Management, Devina holds an Honours in Marketing. “I am very grateful to be awarded this scholarship and excited about this new journey,” says Devina, who is scheduled to begin the programme in October 2020. “I hope to come back to South Africa and contribute to my field of study,” she says.

Devina went through a rigorous application process and had to meet the criteria for selection, one of which is having a minimum average grade point of 75% for her honours.

Prof Brownhilder Nene, Head of Department: Business Management, gave Devina some words of encouragement: “You will never know how far you can go unless you try. Thank you, Devina, for stepping out of your comfort zone and getting this scholarship.” 

The Kader Asmal Fellowship Programme is a South African strand of a broader Ireland-Africa Fellows Programme managed by the Irish Department of Foreign Affairs and Trade. It was set up in 2012 in honour of the late Professor Kader Asmal, and is a fully-funded scholarship opportunity for those who want to develop skills and knowledge to contribute to the achievement of the Sustainable Development Goals in South Africa.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
