This study evaluated 12 mT electromagnetic fields (100–400 Hz) applied during 30 minutes of cold storage (4 °C) of grass carp. EMF exposure was associated with increased CaATPase activity and frequency-dependent changes in protein and lipid oxidation. NMR results suggested altered water–protein interactions, and the…

This preprint describes an in vitro bioreactor-based system to test whether electromagnetic/electrical stimulation affects extracellular vesicles (EVs). Using proteomics and single-vesicle flow cytometry, the authors report that stimulation at physiological current amplitudes can modulate EV content in a…

This in vivo animal study examined how low-frequency electromagnetic field exposure affects antioxidant status in Wistar rats. The authors report frequency-dependent changes in antioxidant enzyme activity and hydroperoxide content in blood plasma. They also propose that LF EMF may stimulate low levels of ROS that…

This in vitro study used voltage clamp recordings of single OmpF porin channels in an artificial bilayer to test effects of UHF EMF (910–990 MHz). The authors report frequency-dependent changes in channel gating, with increased gating frequency and voltage sensitivity and a maximum effect at 930 MHz. Conductance was…
The movement of actin-myosin biomolecular linear motor under AC electric fields: an experimental study.

Jan 1, 2013
This in vitro experimental study examined how an AC electric field influences actin filament (F-actin) movement on a myosin-coated substrate. The authors report that the field induces electro-orientation torque that aligns movement perpendicular toward electrode edges, with alignment increasing with field strength.…

This paper presents a theoretical model of giant phospholipid vesicle deformation in an alternating-current electric field, based on minimizing membrane bending energy and electric-field energy. The model treats the membrane and surrounding aqueous media as leaky dielectrics and reports good quantitative agreement…

This engineering/food science study examined ohmic heating of peaches at 60 V/cm using bipolar pulses across frequencies from 50 Hz to 1 MHz. Heating time to a target temperature and multiple electrical properties were frequency-dependent, particularly for intact tissue. The authors report faster electro-thermal…
