AFRICA MONTH 2023

Theme: Promoting and appreciating knowledge in and from Africa

On 25 May 2023, Africa will celebrate the 60th anniversary of the Organisation of African Unity (OAU), now the African Union (AU). In continuance of the University of the Free State's (UFS) long tradition of commemorating Africa Day and the ideas underpinning it, the UFS will once again celebrate Africa in 2023 by organising diverse commemorations. The commemorations will highlight African indigenous knowledge and its relevance for higher education in South Africa and beyond. The interpretation and transfer of African indigenous knowledge will be celebrated through music and dance.

Africa Day memorial lecture

The highlight of the celebrations will be the Africa Day memorial lecture, hosted by the university's Centre for Gender and Africa Studies on Wednesday 24 May 2023. The speaker is Prof Motlatsi Thabane, formerly of the National University of Lesotho. The title of his presentation is Friendship in the Search for Justice in Mohokare Valley in the Nineteenth Century. The departure point of Prof Thabane’s lecture is the early 19th century. 

He demonstrates that a community of white settlers fleeing British rule in the Cape Colony was added to African communities living in the Mohokare Valley at the beginning of the 1830s. As a result, complex relations developed between African and white settler communities in the Mohokare Valley. Central to those relations was occupation and ownership of land. Driven by different motives and influences, some African communities threw in their lot with incoming white settler communities, while others resisted the alienation of land they regarded as theirs. 

Moshoeshoe I and his followers were among the latter groups. Consequently, relations that developed between Basotho and white settlers were characterised by deep mutual mistrust, tension, and conflict. White settlers were not a monolithic group, however, and among them were individuals who regarded the alienation of Africans’ land as unjust. Josias Philip Hoffman was one such individual. Concerned about the welfare of the Basotho and opposed to the unjust manner in which fellow settlers seized their land, he formed a friendship with Moshoeshoe I, and lent a hand to Moshoeshoe I’s resistance against the alienation of the Basotho’s land. The purpose of the lecture is twofold; first, to celebrate the friendship between these two men, and second, to ask questions about whether we can learn something from this friendship today.

Africa Month book launch 

The memorial lecture will be preceded by a book launch on 22 May. The UFS Library and the Centre for Gender and Africa Studies will facilitate the launch of the book titled, Decolonizing The Mind: A guide to decolonial theory and practice by Sandew Hira, Secretary of the Decolonial International Network (DIN). The book attempts to offer a comprehensive, coherent, and integral theoretical framework that draws on different contributions in the resurgent and insurgent decolonial movement. Hira will use the book launch to make a clarion call for a new world civilisation anchored in the decolonisation of the mind. 

The Africa Month Dialogue, slotted for 26 May and facilitated by the Office for International Affairs, will carry the same theme as the memorial lecture, namely, ‘Promoting and appreciating knowledge in and from Africa’. Together with the Rector and Vice-Chancellor, Prof Francis Petersen, and international partners, we will discuss the meaning and value of African indigenous knowledge, the importance of being creators and co-creators of knowledge in and from Africa, and the importance of African knowledge on the international stage. Of importance is the idea of African ways of being, knowing, and relating. In the engagement, internationalisation of African knowledge will be considered without necessarily compromising Africa’s ability to integrate and engage on a global level. The UFS’ approach to promoting African-produced knowledge and epistemological diversity and disseminating knowledge in and from Africa will be deliberated. 

Hybrid format 

The 2023 UFS Africa Month commemorations will once again take a hybrid format. Besides the Africa Day memorial lecture, the book launch, the Africa Day Dialogue, and various face-to-face functions on all three campuses, there will also be online content on a dedicated website. We are looking for contributions that engage with knowledge. Among others, UFS community members and its international partners are invited to make contributions centred on promoting and appreciating knowledge in and from Africa by way of contributions centred on, but not limited to the themes below: 

Exploring how knowledge in and from Africa is promoted and appreciated

• The role of orality in creating new understanding and insight 
• The potential of oral traditions and oral history for knowledge creation, transfer, and dissemination 
• Women in African knowledge processes

• The national, regional, and global impact of African scholarship
• UFS knowledge collaborations/partnerships on the African continent
• Narratives of research and student excellence associated with African unity 
• Dissemination of knowledge in and from Africa
• Celebrating epistemological diversity in and from Africa.

Other forms of contributions/participation can include, but are not limited to
• recorded performing arts performances (e.g., solo music or poetry);
• virtual visual art presentations;
• written poetry;
• songs;
• short thought/opinion pieces, which can also be published in mainstream media; 
• topical academic writings;
• face-to-face events; and 
• live-streamed events (with links to the Africa Month webpage).

Please share a brief written proposal explaining your planned contribution by 12 May 2023. The proposal should not exceed 300 words and should be emailed to Bhekumusa Zikhali at zikhalibn@ufs.ac.za / Africadaycommemoration@ufsacza.onmicrosoft.com.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
