Investigators: M. Škrátek, J. Maňka Chronic stress is a risk factor for several chronic non-communicable diseases. The chronic release of glucocorticoids and catecholamines during stress is thought to activate mechanisms that induce oxidative stress and inflammation. The transcription factor NRF2 regulates the expression of genes encoding proteins involved in iron metabolism, as well as antioxidant…

Authors of the result: Miroslav Hain, Jozef Klembara Modern digital imaging methods – X-ray microtomography and photogrammetric scanning with subsequent data processing and virtual 3D imaging were developed and subsequently used in the study of palaeontological finds: the holotype of the amniote Brouffia orientalis from the Upper Carboniferous of the Czech Republic and the discovery…

Investigators: Beáta Ondrušová, Jana Švehlíková) VEGA 2/0109/22 As part of her dissertation, B. Ondrušová dealt with the significance of the positions of individual electrodes in the body surface mapping of the electric field of the heart regarding the use of surface ECG maps for the inversion task for the localization of premature ventricular activity (extrasystoles)….

Investigators: Jiří PŘIBIL, Anna PŘIBILOVÁ, Ivan Frollo Our research is focused on the analysis of the effects of scanning in NMR tomograph on the cardiovascular system of the examined person in order to find appropriate methods of their detection and quantification, designing measures for their minimization. The impact of stress effects on the human body…

Investigators: M. Majerová, D. Galusek, M. Michálková, A. Talimian, A. Prnová The research was focused on the development of a new type of aluminosilicate glasses and glass-ceramics with luminescent properties. The effect of Bi on the crystallization kinetics of the gelenite (2CaO-Al2O3-SiO2) glass was investigated. The obtained knowledge can be used in the preparation of…

Investigators: M. Škrátek, P. Billik Ag2O nanoparticles are an exceptional material that has great potential for biomedical applications due to its high cytotoxicity. Although the wet chemical synthesis of Ag2O nanoparticles is a particularly simple preparative technique, it is very difficult to obtain Ag2O in a concentrated state because the precipitation rate is difficult to…

Investigators: Jozef Klembara, Miroslav Hain Using modern digital imaging methods – photogrammetric scanning and virtual 3D imaging, the only known specimen of the early eureptile Coelostegus prothales from the Upper Carboniferous of the Czech Republic was described. Using these modern digital 3D imaging methods, new, highly detailed information on the structure of the individual bones…

Investigators: Beáta Ondrušová, Peter Tiňo, Jana Švehlíková This study addresses the non-invasive localization of cardiac abnormalities, specifically premature ventricular contractions (PVCs), through a newly proposed two-stage inversion solution for a dipole cardiac source. One of the inputs for solving the inversion problem is the surface potentials measured using a large number (128) of electrodes placed…

Investigators: Anna Krakovská, Martina Chvosteková, Jozef Jakubík Identifying causal relationships in measured time series is a research topic that we have been working on intensively for several years. This year we have focused on discovering causality in cases where traditional tools such as the Granger test, successful for example in autoregressive processes, are not applicable…

A. Dvurečenskij, A. Cigáň, , M. Škrátek, M. Majerová, J. Maňka In colloids of metal nanoparticles based on high-entropy alloys (HEA-High Entropy Alloys) in imidazolium-based ionic liquids, the properties of three objects meet: ionic liquids, HEA alloys and nanoparticles. Each of them separately exhibits unique properties that have attracted considerable attention in recent decades due…
