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.”

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
