Numerical and analytical inspection of magnetic field effects in the radical pair mechanism by a simplified rate equation model
Abstract The radical pair mechanism is by now the most prominent candidate for a biologically relevant quantum effect of magnetic fields. Recently, N. Ikeya and J. R. Woodward demonstrated a magnetic field effect for sub-extremely low frequency (ELF) fields in the mT range by investigating the autofluorescence spectrum of flavin adenine dinucleotide in living HeLa […]
Action potential threshold variability for different electrostimulation models and its potential impact on occupational exposure limit values
Abstract Occupational exposure limit values (ELVs) for body internal electric fields can be derived from thresholds for action potential generation. These thresholds can be calculated with electrostimulation models. The spatially extended nonlinear node model (SENN) is often used to determine such thresholds. Important parameters of these models are the membrane channel dynamics describing the ionic […]
The influence of eyelashes on electric field distribution and absorbed power density in the cornea under millimeter‐wave exposure
Abstract As millimeter wave (MMW) technology, particularly in fifth-generation (5G) devices, gains prominence, there is a crucial need for comprehensive electromagnetic (EM) models of ocular tissues to understand and characterize EM exposure conditions accurately. This study employs numerical modeling to investigate the interaction between MMW and the cornea, aiming to characterize EM field distributions and […]
Characterising core body temperature response of free‐moving C57BL/6 mice to 1.95 GHz whole‐body radiofrequency‐electromagnetic fields
Abstract The present study investigated the core body temperature (CBT) response of free-moving adult male and female C57BL/6 mice, during and following a 2-h exposure to 1.95 GHz RF-EMF within custom-built reverberation chambers, using temperature capsules implanted within the intraperitoneal cavity and data continuously logged and transmitted via radiotelemetry postexposure. Comparing RF-EMF exposures (WBA-SAR of 1.25, […]
Protective effect of radiofrequency exposure against menadione‐induced oxidative DNA damage in human neuroblastoma cells: The role of exposure duration and investigation on key molecular targets
Abstract In our previous studies, we demonstrated that 20 h pre-exposure of SH-SY5Y human neuroblastoma cells to 1950 MHz, UMTS signal, at specific absorption rate of 0.3 and 1.25 W/kg, was able to reduce the oxidative DNA damage induced by a subsequent treatment with menadione in the alkaline comet assay while not inducing genotoxicity per se. In this […]
Pulsed electromagnetic fields attenuate human musculocutaneous nerve damage induced by biceps eccentric contractions
Abstract Pulsed electromagnetic field (PEMF) therapy, a noninvasive treatment, has shown promise in mitigating nerve damage. However, unaccustomed exercises, such as eccentric contractions (ECCs), can damage both muscle and nerve tissue. This study investigated whether magnetic stimulation (MS) with PEMF could aid in nerve recovery after ECCs in the elbow flexors. Twenty participants were randomly […]

A comparative study of simulated electric fields of transcranial magnetic stimulation targeting different cortical motor regions
Abstract This computational simulation study investigates the strength of transcranial magnetic stimulation (TMS)-induced electric fields (EF) in primary motor cortex (M1) and secondary motor areas. Our results reveal high interindividual variability in the strength of TMS-induced EF responses in secondary motor areas, relative to the stimulation threshold in M1. Notably, the activation of the supplementary […]
Nonlinearities and timescales in neural models of temporal interference stimulation
Abstract In temporal interference (TI) stimulation, neuronal cells react to two interfering sinusoidal electric fields with a slightly different frequency ( f 1 ${f}_{1}$, f 2 ${f}_{2}$ in the range of about 1–4 kHz, ∣ f 1 − f 2 ∣ $| {f}_{1}-{f}_{2}| $ in the range of about 1–100 Hz). It has been previously observed that […]
