Another year, another round of national and international awards for the Department of Communication and Marketing’s (DCM) campaigns and projects. This year saw DCM pick up an International Association of Business Communicators (IABC) Africa Silver Quill Award of Excellence for Communication Research for Narrative Building Storytelling. This project and subsequent award were in partnership with Development Communication Solutions (DevCom), led by Lacea Loader, Director: Communication and Marketing. 

During the 2022 annual Marketing, Advancement and Communication in Education (MACE) Excellence Awards, DCM won four excellence awards. Dr Nitha Ramnath, Deputy Director: Corporate Relations, won a Silver Award of Excellence for the 2021 Rector’s Concert, and a Bronze Award of Excellence for the 2022 Rector’s Concert. 

Lacea Loader and Martie Nortjé, Manager: Reputation, Brand and Marketing Management, won a Bronze Award of Excellence for the project ‘UFS – Our Story: The building and implementation of a brand narrative.’ Rounding up the UFS’ winning tally was Website Editor, Rulanzen Martin, who won a MACE Bronze Award of Excellence for the 2021 UFS Deaf Awareness Month (DAM) Campaign. The DAM campaign also received recognition during the 2021 IABC Silver Quill awards, where it won a Silver Quill Award of Excellence. 

Awards a perfect opportunity to benchmark 

“The awards give recognition to the communication efforts and endeavours undertaken by DCM as the strategic communication partner at the UFS; it also serves as a perfect opportunity to benchmark against peers and the industry. I am extremely proud of what the team has achieved,” says Loader.  “It is an honour when our projects receive awards, given the calibre of entries submitted for both the IABC and MACE awards programmes. The IABC awards programme is for all industries, while the MACE awards only recognise higher education institutions,” she says. 

For the 2022 MACE Excellence Awards, a total of 95 awards were awarded to 12 institutions from a total of 171 entries.

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.
