Itumeleng Mabusa, analyst in the South African Doping Control Laboratory (SADoCoL) hosted by the University of the Free State (UFS), says women in South Africa and the world at large are still facing the most discrimination in the workplace.

It is time that women realise their brilliant leadership qualities. Women are more sensitive and intuitive and bring a different dimension of leadership to the workplace.

For Itumeleng Mabusa, analyst at the South African Doping Control Laboratory (SADoCoL) hosted by the University of the Free State (UFS), this is one of the ways to address the challenges that women still face. Mabusa believes the opportunities for women are not as prominent as it should be and believe that gender discrimination in the workplace still exists and should be addressed.

Mabusa, who has been a member of SADoCoL since April 2015, analyses urine samples from athletes to test for prohibited drugs in sports. Her day-to-day work involves sample extractions, running the extracts on analytical instruments such as the high-performance liquid chromatography (HPLC) or gas chromatography (GC) machines, and analysing the data to see if there are any performance-enhancing drugs that are prohibited by the World Anti-Doping Agency (WADA).

Women still face the most discrimination in the workplace

According to her, women in South Africa and the world at large are still facing the most discrimination in the workplace. Women still have to fight to get their views across, and they are still not taken seriously because of patriarchal stereotypes. 

“In some corporate settings, women are still remunerated as well as men, regardless of both being in the same position and equally talented. It is hard enough to be equally recognised as a professional in your own field of expertise as a woman, which is exacerbated if you are a woman of colour. The other most pressing issue is the high prevalence of gender-based violence, with women holding the record for high incidents of violence against them,” says Mabusa.

Addressing the challenges

These challenges, says Mabusa, can be addressed by allowing women to do any job that a man can do. Women in leadership are often disregarded and their judgments are always questioned, she says. 

“There has to be more outreach programmes to teach young girls at a very young age that they can be leaders in absolutely any career they desire, from science, engineering, and aviation – to name but a few. Most importantly, leaders should groom the women in their organisations to one day take over the higher positions, and not always leave them for men.” 

“My opinion regarding issues of gender-based violence is that it must be addressed from an early age, in addition to teaching and preparing the girl-child to fend off danger. I think the boy child should also be empowered and taught to be self-sufficient, and not be egotistical, but respectful towards women of any age. Boys and girls should be groomed to be able to co-exist cohesively in a society where they both have equal chances of achieving greatness.”  
What is the most interesting thing to you in the field of anti-doping science?

As a WADA-certified scientist, Mabusa says the best and the worst part of her field is when she has to take part in external quality assessment scheme (EQAS). All the WADA-accredited laboratories in the world must take part in the analyses of the same samples three times a year at the same time. 

“These are both nerve-wracking and exciting all at the same time; it always reminds me of the feeling I used to get when I had to write final exams. I like comparing my statistical results with the rest of the world, for example finding out what quantitative concentration values and Z-scores the rest of the world obtained for their analysis compared to mine.” 

“It is also very interesting to find the scientific evidence and analysis you completed, led to the prosecution of an athlete due to an anti-doping rule violation. I also love doing scientific research and being able to share it with the rest of the world. Working with different analytical equipment and different software – from GC-MS and LC-MS to LC-UV – is exciting,” says Mabusa.  

Community value impacts life as a scientist and woman

Mabusa says as a woman, especially a black woman being given the chance to use her scientific skills as a WADA-certified scientist, it is an honour, as it gives everyone competing in sports in Africa a fair chance to compete. By testing these athletes, she explains, she is making sure that everyone plays fairly without their performances being influenced by any prohibited drugs. 

“Among the prohibited drugs are also drugs of abuse, including for example, cocaine and MDMA (ecstasy). By testing athletes for these drugs, I am helping the athletic community to try to stay off illegal recreational drugs.” 

Playing her part in the Olympics and coping with challenges

With the Olympic Games taking place between July and August, Mabusa says it is a great feeling to know that she is part of a team of scientists who are producing test reports that will ultimately determine whether tested athletes will be eligible or banned from representing their African countries at the Games.

According to her, they have a high volume of samples to analyse on a daily basis, because of all the sports competitions in South Africa and the continent in preparation for the Tokyo Olympics. 

Mabusa says the challenges associated with this work include the extremely strict rules of analysis, called the International Standard of Laboratories (ISL), set for all accredited laboratories to follow. The strict timelines that they all have to stick to in order to report the results to clients on time – no matter how many samples there are – is also a challenge. 

“This means analysing a large amount of data as accurately as possible in the shortest time I can. A skill I had to harness and embrace and learned to perfect over time, is the ability to pay very close attention to detail; this comes in handy when dealing with analytical work.” 

“There is also countless paperwork to fill in in order to follow a chain of custody for a sample. Each and every step gets recorded, from sample reception all the way to reporting; paying attention to detail comes in quite handy through all this,” says Mabusa.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
