Research ties between the University of the Free State, the University of Tokyo, and the International Christian University strengthened when the Japanese scholars visited the Afromontane Research Unit (ARU) on the Qwaqwa Campus. 

“The visiting delegation is part of the larger research group on sustainability studies that has been sharing research expertise with the Afromontane Research Unit’s researchers over the past three years,” said Dr Kudo Shogo, Assistant Professor from the University of Tokyo’s Graduate Programme in Sustainability Science – Global Leadership Initiative (GPSS-GLI).

Entrepreneurship in Qwaqwa
“Our focus this time is on entrepreneurs who have had exposure to megacities such as Johannesburg and Cape Town, and who are finding themselves back in places like Qwaqwa. We have discovered that they actually find Qwaqwa more resourceful than when they left. Two to three years of unstable living in the cities gave them a fresh view to see the many opportunities in Qwaqwa and they then start their businesses. Talking to the Qwaqwa entrepreneurs has been a great learning experience for all of us,” he added.

The visiting scholars conducted interviews with 10 local entrepreneurs to get a sense of how they use entrepreneurship for sustainability purposes.

“We are pleased by the local people’s understanding that local problems require local solutions. I would really like to contribute to these people’s understanding of how these solutions fit the problems better than solutions that come from outside. We have quite a number of voices talking about empowering Qwaqwa, with the emphasis on creating jobs for Qwaqwa, solving the problems that Qwaqwa is facing. I have found education to be a unifying factor through tutoring, after-school classes, mentorship, and the personal imperative of sharing,” said Emilie Jones, originally from the United States of America and now studying for a master’s degree in Sustainability Science focusing on water supply and resources.

Education and arts empower communities
“Most of the entrepreneurs we spoke to have experience of the big cities. For them, Qwaqwa is very close to the heart and is home. There are challenges, but they are doing their best to empower their community with ideas and skills from the big cities. They provide services such as education and arts to empower the community to come up with a local identity,” said a PhD candidate, Ven Paolo Valenzuela from the Philippines. 

“I was impressed with the people who realise the opportunities to identify problems and even come up with solutions themselves. A lot of communities can learn from this,” said Gema Carlota Cubelos Perez, a PhD candidate originally from Spain.

Their host, Dr Melissa Hansen, Lecturer from the Department of Geography, said the visit was part of the bigger study on migration and sustainable development. “This was a Global Field Exercise (GFE) for teaching research methods in the field. We found that Qwaqwa is overflowing with potential for entrepreneurship in a wide variety of fields and that there is a strong, vibrant network of young individuals brimming with talent. We are learning from each other, as Akita City in Japan and Qwaqwa are similar in more ways than one,” she said.

One of the entrepreneurs, Refiloe Seekane, is a self-taught fashion designer, choreographer, and event coordinator. “The interview has actually made me realise the gaps we have for business opportunities in Qwaqwa and the importance of implementing some of the projects I have been planning for years,” said Seekane, a second-year Education student and CEO of Evomind.

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.
