Renata van Reenen
Renata van Reenen has been a South African Sign Language (SASL) champion since primary school, and she is using her postgraduate degree to further SASL in higher education.

Renata van Reenen, a master’s student at the University of the Free State (UFS), recalls how a school talk in 1998 by Deaf activist Johan Gouws instilled in her a kind of ‘duty’ to become a champion for Deaf people. Van Reenen, who in 1987 became the first Deaf child in South Africa to receive a cochlear implant, says it was at this talk that she realised that, as a Deaf person, she has her own language, identity, and culture – and that she is not “a person with a disability”. 

Van Reenen is currently a language facilitator in the UFS Department of South African Sign Language (SASL) and Deaf Studies, and she believes that Deaf students should be empowered to embrace their attributes. Her interests include exploring different sign languages around the world, Deaf issues, and how Deaf children are supported in schools for the Deaf. “One of my hobbies is to put my creative ideas on paper, and I would like to develop and record these stories in SASL so they can be accessible to Deaf schools as resource materials,” she says. “These materials would then also be accessible when teaching the subject South African Sign Language as a Home Language.”

Van Reenen, who worked as an assistant teacher at a school for the Deaf for seven years, is passionate about SASL and the lived experiences of the Deaf. We asked her to share some views on empowering the Deaf and SASL: 

Why is it important to empower Deaf students?

When I was 17, I had no Deaf identity. I did not understand sign language and how it was used – when the Deaf person gave a speech at the school, it changed my life. I realised that I am a Deaf person with my own language, identity, and culture, and that I am not a person with a disability. I strongly believe that Deaf students need to be empowered to fully embrace their identity, language, and culture, and through this expectance show the world who we are. My favourite motto I always share with my Deaf learners is: “Believe in yourself, show them what you can do.” I also encourage them to continuously teach Hearing students the beautiful language, as the famous Deaf quote states: “Sign language is the noblest gift God has given to Deaf people.” George Veditz, the former president of the National Association of the Deaf of the United States, said, “As long as we have Deaf people on Earth, we will have signs.” He protected our language at a time (the early 20th century) when the world strongly believed that Deaf people had to learn through oralism and had to learn spoken language in order to function as a “normal person” alongside hearing people.

As a Deaf person, do you believe the UFS community is doing enough to accommodate you, and how do you feel about being part of the Department of SASL and Deaf Studies? 

When I received a link for a workshop I had to attend, I was so overwhelmed when I saw the interpreter on the video link, and knew that it would be extremely helpful for me during my research. The UFS Centre for Universal Access and Disability Support made sure I have full access to any workshops the university provides. It is amazing that my supervisor can also sign. That made me feel at home, being in a Deaf world without communication barriers. The department is an amazing team that supports and encourages me during my studies.

What will you be doing in honour of Deaf Awareness Month?

The SASL Department and I, along with Deaf Studies, have organised a “Signing Space” event in September to bring Deaf and Hearing students together to socialise with each other. This event will give Hearing students the opportunity to learn about the Deaf world. During this event I will give a small presentation such as “Poetry in SASL” that will show that Deaf people have their own literature, and that it forms part of their language, SASL. We will not only focus on presentations but also on fun activities, such as games that are prominent within the Deaf community. 

Why did you decide to pursue your MA at the UFS? 

During the coronavirus pandemic I applied to the University of Gallaudet in Washington, DC to study for a Master of Education in Sign Language degree. Gallaudet is the world's only university in which all programmes and services are specifically designed to accommodate deaf and hard of hearing students. I was accepted to study further and to ultimately become a teacher or lecturer. My aim was to train Deaf adults to qualify in different areas of SASL, ranging from SASL Linguistics, SASL Pedagogy, SASL Media Production, and so forth. In an ideal world these could be offered as short courses through some tertiary institutions which already offer SASL on undergraduate and postgraduate levels. Unfortunately, I did not have enough support, but I did not let it stop my dream. I decided to change my university of choice and applied at the University of the Free State. I am pursuing my MA degree and continuing my studies as a Deaf person. The University of the Free State is providing and recognising SASL. This is a positive step, as South African Sign Language will soon be the twelfth official language of South Africa.

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.
