Investigators: A. Cigáň, A. Dvurečenskij, M. Škrátek, M. Majerová, J. Maňka Ionic liquids – liquids composed only of ions, have unique physicochemical properties, such as high thermal and chemical stability, the ability to dissolve various substances and negligible vapor pressure. These properties presuppose their use for the development of new technologies for the production of…

Non-invasive preoperative localization of the site of premature ventricular activation can significantly shorten the time and increase the success of ablation therapy. A method was proposed to locate the lesion by solving the inverse problem of electrocardiography as finding the position of the dipole representing the onset of ectopic activation. The method requires surface ECG…

Optimized X-ray microtomographic methodologies of three-dimensional visualization of biological objects and their internal microstructures were developed. Optimization of microtomographic measurements for a specific object included the choice of target material, optimized acceleration voltage and X-ray tube current, signal accumulation time on the detector, number of repetitions, choice of relaxation time between two measurements and number…

Investigators: M. Teplan, I. Bajla, R. Rosipal) When monitoring patients with severe head injury, the so-called method is used in clinical practice. critical value of the intracranial pressure time course (VLT). Exceeding this threshold is evaluated as an alarm situation, on the basis of which the medical staff initiates an emergency procedure (protocol) to save…

(Investigators: J. Přibil, I. Frollo, D. Gogola, T. Dermek) During scanning in a magnetic resonance (NMR) tomograph, mechanical vibrations occur due to the function of the coils of the gradient system and acoustic noise is subsequently generated. This is a source of interference, especially in 3-D imaging – an increase in background noise and a…

(Investigators: A. Krakovská, F. Hanzely) The data that is the subject of causal analysis is often in the form of time series. In such cases, we usually reach for a standard Granger causality test. However, it is based on autoregressive models and can only be successfully used with stochastic, linearly interconnected systems. The method of…

(Investigators: J. Švehlíková, J. Zelinka, L. Bachárová, M. Tyšler) Using a computer model of the ventricles, we simulated and visualized the spread of the activation front in the heart chambers at normal rate, in cases of local slowing of the activation queue, thickening of the left ventricular wall and a combination of both factors present…

(Investigator: M. Škrátek) Biodegradable polymer nanocomposites represent a promising group of plastics usable for various bio- and enviro-friendly applications, such as drug carriers or biological plastics with shape memory. Polymers are generally electrically non-conductive and non-magnetic materials. Natural Halloyzite nanotubes (HNT) modified with iron oxide nanoparticles were used to improve the mechanical properties of the…

(Investigators: L. Valkovič, I. Frollo) Cardiovascular disease, obesity and diabetes are very often accompanied by changes in the energy metabolism of skeletal muscle. Therefore, modern medicine is placing increasing emphasis on research into new non-invasive methods for measuring energy metabolism. In line with this trend, new methodologies for determining oxidative metabolism using static and dynamic…
