Dr Lazlo Passemiers
Dr Lazlo Passemiers spent six years conducting research across three continents.

A keen interest in unravelling transnational histories of 20th-century Southern Africa led Postdoctoral Research Fellow Dr Lazlo Passemiers to spend six years conducting extensive research across three continents. Dr Passemiers sifted through archives in Africa, Europe, and the US in order to convert his PhD thesis into a monograph.

It was on 17 July 2019 that the fruits of Passemiers’ labour were officially launched by the International Studies Group at the University of the Free State’s Bloemfontein Campus. His book, Decolonisation and Regional Geopolitics: South Africa and the ‘Congo Crisis’, 1960-1965, offers an important shift in the historiography of the Congo Crisis. It creatively centres African involvement in the debate by examining this event from a regional geopolitical angle. 

Going back in time 

By providing a three-fold perspective that examines decolonisation, apartheid diplomacy, and Southern African nationalist movements, the book offers a rounded picture of South African involvement in the Congo Crisis.

Dr Passemiers’ fascination with the transnational dynamics of Southern Africa’s history has rippled into two new research projects that respectively explore “the connection between decolonisation and white flight in the region as well as the transnational support networks of liberation movements”.

Finding the missing pieces of the puzzle

Prof Christopher Saunders, Emeritus Professor at the University of Cape Town, commended Dr Passemiers’ historiographical contribution: “He has identified a major gap in the literature and he has filled it admirably by looking across the spectrum.” As Prof Saunders noted, “what has been missing in the literature is the African angle.” 

Literature’s role in transformation

The process of undoing the profound impact of colonialism on society is long and difficult and important in this process is a clear understanding of history, which Dr Passemiers’ book enhances.

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.
