" Although observed results give satisfying answer to questions whether or not electromagnetic fields could affect cell cultures even at non-thermal levels, the research presented herein opens a multitude of questions about the exact physical mechanisms underlying the observed microorganism behavior." {Credits 1} " The Ion Parametric Resonance (IPR) theory, proposed by Lednev [25], [26] and [27], is one of the most discussed models of LF EMF interaction with biological objects. The assumptions of this theory published works regarding LF EMF effects on yeast are based on the Ion Cyclotron Resonance theory (ICR), first described by Liboff [24], speculating that the physiological activity of certain important ions can be altered when the frequency of applied time varying magnetic field is equal to the frequency of ion motion in a static magnetic field. Ions in IPR model are represented by a harmonic oscillator, bound to a specific location at the surface of the cell membrane, and application of combined magnetic field should alter its oscillations." {Credits 1} " From the experimental results it is clear that all sub- harmonic frequencies have shown inhibitory effects and statistically significant biological responses are present at frequencies 0.8 and 0.4 kHz, as well as the base frequency. These frequencies correspond to the ion parametric resonance frequency of Ca 2+ ions, and harmonic components." {Credits 1} {Credits 1} 🎪 Radil, R., Barabas, J., Janousek, L., & Bereta, M. (2020).
