Investigators: Ladislav Valkovič, Ivan Frollo Alterations in cardiac metabolism are indicative of several diseases. Current data acquisition methods of phosphorus MR spectroscopy (31P-MRS) are even at 7T systems too slow to allow investigations of dynamicchanges or measurements under stress. Therefore, we have developed a new method of spectraspatial encoding, which substitutes typical Cartesian sampling with…
Investigators: Jiří PŘIBIL, Anna PŘIBILOVÁ, Ivan FROLLO, IMS SAS Our research is focused in analyze and monitoring of a mental and physiological state of an examined person during scanning in the magnetic resonance imaging (MRI) device working with weak magnetic field up to 0.2 T. Our final aim is to detect and suppress negative…
Investigators: Michal Teplan, Hoang Vu Viet In the area of the effect of pulsed electric fields (PEF) on sub-cellular structures, we investigated the manipulation of microtubules (MT) using PEF. In cooperation with ÚFE AVČR, we created new statistical measures for measuring MT movement for images from the “single molecule TIRF” microscope, which we called “microtubule…
Investigators: Viktor WITKOVSKÝ, Gejza WIMMER, Jr., Laura HAJZOKOVÁ Institute of SAS Measurement, v.v.i. + foreign partners In collaboration with our partners, we investigated the problem of understanding endogenous chronic pain with the aim of finding and elucidating mechanisms to alleviate suffering. Therefore, we focused on studying the course of brain activity in patients with migraine…
Investigators: Lehocki F., Tyšler M., Gogola D., Bagín R., Madevska Bogdanova A., Koteska B., Spasenović M., Vićentić, T. et al. As part of the NATO project, sensors were designed and methods were developed for monitoring the vital functions of mass casualty victims using a wearable system. The proposed resistive sensors based on laser-deposited graphene layers…
Investigators: Roman Rosipal, Zuzana Rošťáková The detection and changes of oscillatory rhythms in the EEG signal are important for understanding the processes taking place in the human brain during experiments aimed at modulating brain activity, as well as for the proper functioning of the brain-computer interface. In [1], we created a set of simulated EEG…
Investigators: Přibil Jiří, Přibilová Anna, Frollo Ivan In many people, exposure to acoustic noise and/or vibration causes negative psychological reaction that can be identified with negative emotional states of anger, fear, or panic. Recognition of these negative affective states in the speech signal of the noise-exposed speaker may be used as another stress indicator….
Institute of Measurement of the Slovak Academy of Sciences in 2021 actively participated in the solution of two European COST projects focused on multimodal and correlated imaging methods. The project COST CA16101 “Multi-modal imaging of forensic science records – tools for forensic science (MULTI-FORESEE)” was focused on multimodal imaging in the field of forensic science…
Investigators: Michal Teplan, Martin Bereta Oxidative metabolism is a process that occurs in organisms during their physiological and pathophysiological conditions. Monitoring biological oxidation processes caused by chemical or physical stimuli is currently extremely important due to the environmental burden of various physicochemical factors. Existing techniques usually require the addition of chemical markers or illumination, which,…
Investigators: M. Škrátek, J. Maňka Measurement of magnetic quantities with high sensitivity finds application in various areas of scientific research. In our research, in cooperation with other scientific institutions, we focused on the use of nanoparticles in biomedicine and on two issues in the field of materials research. Ultra-small superparamagnetic iron oxide nanoparticles in…
