Dr Satyajit Tripathy, a postdoctoral fellow from the Department of Pharmacology and Physiology, won the medal for the best oral performance at a UNESCO/UNITWIN network web seminar attended by more than 300 people from various institutions around the world.

A postdoctoral fellow in Pharmacology at the University of the Free State (UFS) was awarded a medal for the best oral e-poster presentation (Postdoctoral Fellow category) at a UNESCO/UNITWIN Network web seminar.

The two-day webinar with the theme Current concepts of Environmental Pollution by Electromagnetic field and Coronavirus was held in early August and was attended by more than 300 delegates from approximately 30 institutions from different countries.

Dr Satyajit Tripathy from the Department of Pharmacology won the medal for his outstanding research presentation on Employment of old options to control novel Coronavirus: Pros and Cons (authors: Barsha Dassarma, Satyajit Tripathy, MG Matsabisa). His presentations looked at immunotherapeutic techniques, such as the convalescent plasma (CP) therapy and possible diverse modes of action of the antimalarial drug hydroxychloroquine (HCQ) against COVID-19 infection.

The award will serve as motivation

He was excited to hear that he had won the award, says Dr Tripathy.

“I never thought I would win, but I tried my best. On the topic of possible modes of action of HCQ against the viral infection, we have published in the ‘International Journal of Antimicrobial Agents’ (S Tripathy, B Dassarma, H Chabalala, S Roy, and MG Matsabisa / International Journal of Antimicrobial Agents 56 (2020) 106028). All the authors are grateful to Prof Glen Taylor, Research Director at the UFS, and the UFS Department of Pharmacology, for giving us the opportunity,” says Dr Tripathy. 
According to him, receiving this award is a validation and boost to his confidence. “I am thankful to Prof Motlalepula Matsabisa (supervisor) and Dr Barsha Dassarma (my wife), who are also contributing actively to this project. Moreover, the award is a symbol of respect for my work and the acceptance of a greater responsibility to keep the UFS flag flying high.”
Dr Tripathy goes further to say that it will motivate him to work on HCQ or nano-HCQ delivery research on Coronaviruses. In his doctoral study, it has been found that chitosan-based nanochloroquine delivery increases antimalarial efficacy against rodent parasites. Against the Coronavirus, this type of approach might work to reduce the dose and increase the efficacy of HCQ, explains Dr Tripathy. 

Immediate saviour from the pandemic

In his presentation, Dr Tripathy argues that while the world is finding expedited approvals for the development of vaccines that are time-dependent, preventative, and possibly not a cure, physicians are considering the convalescent plasma (CP) therapy as an immediate saviour, and the antimalarial drug hydroxychloroquine (HCQ) as therapeutic options against COVID-19 infection, after assessing results from larger prospective, randomised, dose-determining controlled clinical trials. 
He concludes that, “Overall, in this situation of unavailability of specific medication, the CP therapy and HCQ treatment might act as an immediate saviour for society from the pandemic.”

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
