July 6-11, Poland hosted the 44th Congress of the Federation of European Biochemical Societies “From molecules to living systems” bringing together scientists from Austria, Brazil, Germany, Spain, Italy, the USA, France, Sweden and other countries. RUDN University was presented by researchers from the Institute of Biochemical Technology and Nanotechnology (IBCTN) – assistant lecturer Vera Zhilkina and graduate student Anastasia Stoynova.
Among the key topics of the congress are plant biotechnology, bionanotechnology, polymer synthesis for biomedicine, synthetic networks and systems, analysis and visualization of individual cells, women in science, education in the field of biochemistry and molecular biology. Vera Zhilkina made a presentation “Methods for the identification and quantitative analysis of biologically active substances from vitamin plants raw material” in the section “Plant biotechnology”. Abstracts were published in a special issue of FEBS Open Bio, indexed in WoS.
“In the production of medicines from plant materials, standardization is important - what parameters to use for standardization, whether it is possible to use the material, what is the chemical composition of the raw materials, how many biologically active substances - for example, flavonoids there are. Using the example of wild rose and vitamin brew No. 1, we have proved the effectiveness of the spectral identification technique for three absorption maxima. This technique allows for express analysis and selection of high-quality medicinal plant materials, which means improving the quality of drugs. We also established parameters that increase the selectivity of the method in the quantitative analysis of raw materials and preparations based on them. We patented this technique, so the result of the work of a full scientific cycle was presented at the Congress, ” said Vera Zhilkina, Assistant lecturer of the Institute of Biochemical and Nanotecnology.
Anastasia Stoynova made a report “Diagnosis of the thyroid gland diseases: nanotechnology in the development of diagnostic test systems” in the section “Bionanotechnology”.
“The goal of the FEBS community is to organize an international forum for the direct exchange of knowledge and ideas in the field of molecular life sciences. The event has become a successful platform for close international cooperation and scientific collaborations,” said Anastasia Stoynova, graduate student of IBCTN, RUDN University.
A RUDN chemist has obtained a new compound — a dumbbell-shaped phosphate-bridged molybdenum cluster. The cluster accelerates the reaction of the formation of sulfides from oxides and can be used in pharmaceutical and cosmetic manufacturing.
Mathematicians from RUDN University have studied the properties of compositional operators in spaces with mixed Lebesgue norms. It will help describe the diffusion of liquids in materials with cracks and in porous materials. Such spaces are also useful for obtaining estimates for solutions to the Navier-Stokes equation.
A biophysicist from RUDN University and his colleagues modelled the molecular dynamics of growth of microtubules, the most important elements of cell activity. The researchers have built a model for the interaction of microtubule subunits, which takes into account their internal and external connections. The results will help form a more complete model of the dynamic instability of microtubules. It will allow choosing chemical agents for the treatment of certain diseases, including neoplasms and neurodegenerative pathologies.
