The project “Novel Composites based on Cerium Oxide Nanoparticles and Carbon Enterosorbents for Acute Radiation Sickness Therapy” (project G5683) is coordinated by Prof. Svitlana Lyubchyk, leading researcher of the Associação para a Inovação e Desenvolvimento da FCT, Universidade Nova de Lisboa, Portugal. The consortium includes the researchers from the; the Vernadskii Institute of General & Inorganic Chemistry, NAS of Ukraine; the Kavetskii Institute of Experimental Pathology, Oncology & Radiology, NAS of Ukraine, Department of Biophysics and Department of Magnetism of Institute of Experimental Physics in Kosice and Departamento de Quimica Inorganica, Universidad de Alicante in Spain. In the next 3 years members of the research groups will design and test the novel nanocomposites for the treatment of acute radiation sickness based on the combined use of uncoated nanocrystalline cerium dioxide and the newest highly active oral dispersible carbon enterosorbents. The practical result of the study will be an experimental implementation of a completely new approach to mass therapy of acute radiation sickness, compatible with classical cytokine therapy. It is expected that the research will lead to a new medicinal product ready to be tested in a preclinical trial.
