Dr Satyajit Tripathy
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.”

UFS PhD student receives more than R5,8 million to take agricultural research to African farmers

Bright Peprah, a Plant Breeding PhD student from Ghana in the Department of Plant Sciences at the University of the Free State received an award from the competitive Program for Emerging Agricultural Research Leaders (PEARL) of the Bill and Melinda Gates Foundation (BMGF) for one of his projects.

From the more than 750 proposals for funding that were received from African researchers, only 19 received funding from PEARL. PEARL is an agricultural initiative by the BMGF to take agricultural research products to African farmers. It also aims at involving the youth and women in agriculture.

Peprah’s proposal to introgress beta carotene into farmer-preferred cassava landraces was part of the final 19 proposals funded. The project is being led by the Council for Scientific and Industrial Research (CSIR)Crops Research Institute (CRI), and has the International Institute of Tropical Agriculture (IITA) and the International Centre for Tropical Agriculture (CIAT) as international partners with Peprah as the principal investigator.

He received $473 000 (R5,8 million) for his project on the improvement of beta-carotene content in cassava.

Peprah decided on this project because the populations of underdeveloped and developing countries, such as Ghana, commonly suffer undernourishment and/or hidden hunger, predisposing them to diseases from micronutrients deficiencies. “Vitamin A deficiency constitutes an endemic public health problem which affects women and children largely,” he says.

“In Africa, cassava is widely consumed by the populace. Unfortunately, in these areas, malnutrition is endemic to a significant extent, partly due to the low micronutrients in this tuberous root crop, which is a major component of most household diets. It is for this reason that the development of nutrient- dense cassava cultivars needs much attention to eliminate the ramifications of malnutrition among the poor in an inexpensive and more sustainable way.

“To date we have selected top eight genotypes from germplasm collected from the International Institute of Tropical Agriculture (IITA) which are high in carotenoids and also poundable, a key trait to Ghanaian farmers. These eight genotypes have been planted at different locations in Ghana, and being evaluated by different stakeholders (consumers, researchers, producers, commercial farmers, processors, etc.). If found suitable, the genotypes will be released to farmers, which we hope will solve some of the micronutrient problems in Ghana.

“My projects seek to develop new cassava varieties that will have both high dry matter and beta carotene which has been reported to be negatively correlated (as one increase, the other decreases). The breeding method will be crossing varieties that are high in beta carotene with those with high dry matter, and checking the performance of the seedlings later. Developing such new varieties (yellow flesh cassava) will increase their adoption rate by Ghanaian farmers,” he said.

Prof Maryke Labuschagne, Professor in Plant Breeding in the Department Plant Sciences and Peprah’s study leader, said: “This project has the potential to alleviate vitamin A deficiency in the West African region, where this deficiency is rampant, causing blindness in many people, especially children."
