Sikhululekile Luwaca named 100 Young Mandelas of the future
Sikhululekile Luwaca was recently named as one of 100 Young Mandelas of the future by News24 for his embodiment of Nelson Mandela’s characteristics.
On Tuesday 3 July 2018, News24.com announced the 100 Young Mandelas of the future. Among those nominated was Sikhululekile Luwaca, a former president of the Student Representative Council (SRC) at the University of the Free State (UFS).
 
“It is humbling. I embrace collective action and it would be unfair not to appreciate all the great minds I have encountered over the years and had the privilege to work with. Our individual progress can never be separated from that of the community. It is no longer I that lives, but us, we,” said Luwaca.

Six million readers nominated 1 000 South Africans from all walks of life who could be considered Mandelas of the future. Luwaca emerged in the Visionary category as one of the 100 who made the cut. The initiative was inspired by what would have been Nelson Mandela’s 100th birthday on 18 July 2018. “News24 set out to honour 100 young South Africans who embody the characteristics Mandela was best known for,” said a statement by News24.

While he was the SRC president, Luwaca’s office played a critical role in raising R1.2 million for underprivileged students. He continues to make major strides as the current chairperson of the UFS African National Congress Youth League (ANCYL). 

His social and political influence goes back to when a 13-year-old Luwaca founded an association that sought to address school dropouts in rural areas. In high school, the young philanthropist established an organisation that collected and distributed food for needy elders of Cathcart township in the Eastern Cape. For five years Luwaca served the Student Christian Organisation as chairperson. In 2013, he co-founded the Ubuntu School Project that donated 100 full school uniforms to Phomolong High School learners in Tembisa.

Later on as a UFS student, Luwaca helped found the Hand2Hand Student Association which drives fundraising initiatives, as well as the collection of non-perishable food items and second-hand textbooks for disadvantaged students. In 2015 he was elected a Residence Committee representative for House Outeniqua and SRC: Dialogue and Association. 

Luwaca was instrumental in facilitating a series of dialogues on transformation such as the Fees Must Fall movement and the Shimla Park incident.

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.
