We studied the effect of a low-frequency (LF) electromagnetic field (EMF) on the state of the antioxidant system of Wistar rats in vivo. It was found that changes in activity of antioxidant enzymes and HO content in the blood plasma of rats exposed to LF EMF depended on the frequency of EMF. We propose a mechanism of the protective effects of low doses of ROS the generation of which is stimulated by LF EMF.

Effects of 60 Hz non-uniform electromagnetic fields (EMFs) on the tomato (cv. L-05) seed germination, photosynthesis, and seedling growth under salt stress and laboratory conditions were investigated. A previous trial investigated the impact of salt stress levels (0, 40, 60, 80, and 100 mM NaCl) on tomato seeds, and the 100 mM NaCl level was selected to study the effects of EMFs in attenuating salinity stress on germination, physiology, and growth of tomato seedlings.

Cell lysis is the starting step of many biomedical assays. Electric field-based cell lysis is widely used in many applications, including point-of-care (POC) applications, because it provides an easy one-step solution. Many electric field-based lysis methods utilize micro-electrodes to apply short electric pulses across cells.

Two-dimensional van der Waals (2D vdW) materials have attracted widespread research interest due to their unique physical properties and potential application prospects. In this study, an atomistic-level dynamical simulation method is employed to investigate the chirality of antiferromagnetic resonance modes in CrI bilayer. Beyond the typical observations of a linear increase in high-frequency resonance mode and a linear decrease in low-frequency resonance mode, we have identified a distinct magnetization precession chirality in the CrI bilayer at low magnetic fields: Spins in different layers exhibit opposite precession chirality.

The electrical conductivity of human tissues is a major source of uncertainty when modelling the interactions between electromagnetic fields and the human body. The aim of this study is to estimate human tissue conductivities in vivo over the low-frequency range, from 30 Hz to 1 MHz. Noninvasive impedance measurements, medical imaging, and 3D surface scanning were performed on the forearms of ten volunteer test subjects.

Background/objectives: Autism Spectrum Disorder (ASD) are neurodevelopmental disorders marked by challenges in social interaction, communication, and repetitive behaviors. People with ASD may exhibit repetitive behaviors, unique ways of learning, and different ways of interacting with the world. The term "spectrum" reflects the wide variability in how ASD manifests in individuals, including differences in abilities, symptoms, and support needs, and conditions characterized by difficulties in social interactions, communication, restricted interests, and repetitive behaviors.
