Effects of low-frequency and pulsed electromagnetic fields at a cellular level
Účinky nízkofrekvenčných a pulzných elektromagnetických polí na bunkovej úrovni
Program: VEGA
Duration: 1.1.2025 – 31.12.2028
Project leader: Mgr. Teplan Michal, PhD.
Annotation: Although there is ongoing interest in the adverse and beneficial effects of electromagnetic fields (EMF), a clearexplanation of EMF\’s influence on living structures is lacking. To investigate low-frequency (LF) magnetic fields(MF), we will enhance our experimental platform to test their possible inhibitory or stimulatory effects based onfrequency and magnetic flux density parameters. As a model organism yeast strain Saccharomyces cerevisiaewill be used. Its response to time-harmonic and pulsed MF will be studied by measuring cell growth curve usingturbidimetry, impedance spectroscopy and microscopy. Moreover, the ion parametric resonance interactionmodel will be verified for biogenic ions and the magnitude of the ambient static geomagnetic field. The importanceof this area of research lies in exploring physical methods for manipulating biological structures, with potentialbenefits for biotechnology and medical treatment.
MRCartilage – Automatic data evaluation tool from the longitudinal quantitative MRI studies of articular cartilage
Automatický softvérový nástroj na výhodnocovanie kvantitatívnych MRI štúdií artikulárných chrupaviek v čase
Program: SRDA
Duration: 1.7.2022 – 30.6.2026
Project leader: Ing. Dr. Szomolányi Pavol, (PhD.)
Annotation: The aim of the project is to design a comprehensive tool for automatic evaluation of human articular cartilage data from quantitative MRI. Data obtained from the Osteoarthritis Initiative database, and measured at Institute of Measurement Science and Medical University of Vienna will be segmented using an automated segmentation tool based on convolutional neural networks. The annotated data will then be registered on quantitative MRI data that will be available from the database (T2 and T1rho mapping, gagCEST, sodium MR) using automated or semiautomated tools developed within this project. The data obtained will be evaluated at multiple time points according to MR measurements that will be available. In addition to quantitative MR data, this will include volumetric data, cartilage thickness, and texture analysis of quantitative maps. Patient evaluation will be based on risk factor groups (transverse ligament rupture, meniscus rupture and menisectomy). The expected number of patients is approximately 4000 divided into individual groups in the ratio 40/30/30. The output of the project will be a compiled version of an automatic cartilage evaluation tool that will be available in a public source (such as website of Institute of Measurement).
