Bold and fearless - Prof Aliza le Roux.

Prof Aliza le Roux is Associate Professor in Zoology and Entomology, and Assistant Dean in the Faculty of Natural and Agricultural Sciences on the UFS Qwaqwa Campus. 

A researcher at heart, and with a passion for researching wild mammals, small carnivores, and primates, Prof Le Roux says she is extremely curious and loves to know about a lot of different things.

I decided that I wanted to do something with wildlife, so I completed a BSc degree at Stellenbosch University. One day a professor said: “I just got back from doing research – we were catching lizards along the Orange River” – and I remember thinking, ‘yes, I can see that as my life’. Research is a fantastic career for anyone with curiosity and perseverance. You must have a good dose of bull-headed persistence. We all have the baseline intelligence, but anyone who has studied up to PhD will tell you that it is the persistence that carries you through.

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

What drew me into a career in research was Dian Fossey, an American researcher who was known for undertaking an extensive study of mountain gorilla groups. She had the guts to go out there and be there in the wilderness as the only woman there, doing stuff under extremely difficult conditions. 

Recently, it will be Simone Biles – she does the most mind-blowing stuff with gymnastics – who said she could not go forward with competing in the Olympics because of health reasons. I cannot imagine what guts it takes to say no at such a high-profile sporting event. The ability to say no is something that few of us possess, so right now she is a person I would love to celebrate. I am inspired by women who have the guts and the fact that you believe enough in yourself to do something, despite what others might have to say about it. 

What is your response to current challenges faced by women and available platforms for women development?
There is never enough support or platforms available for the development of women while you have domestic violence and GBV at such insane rates in this country. It’s still a women’s problem, whereas its men perpetrating this and women implicitly supporting it in the way we raise young men and respond to things such as rape accusations. 

It’s a societal problem, and I personally will not be happy until I see this changing in the country. You can look at the massive inequalities and gender biases and the things that are stacked against women, and then feel overwhelmed and step back and say this is too big a problem, I can’t do anything about it. You might not be able to tackle the big problem, but you can chip away at it. Everybody must contribute in a small way. 

What advice would you give to the 15-year-old you?

Be bold. Be fearless. I slowly started becoming like that at that age, but I could have started earlier. I should have told her I was gay; that would have helped. 

What would you say makes you a woman of quality, impact, and care?

There’s a healthy dose of guts and believing in yourself – that is the only way to make an impact. You cannot make an impact if you are doubting your own value, and this is difficult, because we are raised in many instances to be meek, raised to not be leaders but followers, and it’s difficult to overcome that and realise that you are bringing something unique to this world. 

The university is taking some very good steps with the mentorship programmes that it supports. But I would love to see more mentorship for students. Young men and young women in our care being inspired to talk and rethink how they treat women and what equality really means. We need to create more reflective people.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
