Effect of short-term extremely low-frequency electromagnetic field on respiratory functions

Research RF Safe Research Library Jan 1, 2025

This animal study tested whether short-term ELF-EMF exposure alters respiratory physiology in rats. Twenty Wistar albino rats were assigned to control or EMF exposure (50 Hz, 0.3 mT for 2 minutes) with respiratory parameters measured before, during, and after exposure. The study reports changes during exposure (lower…

The In Vitro Enhancement of Retinal Cell Viability via mA and mC RNA Methylation-Mediated Changes in the Levels of Heme Oxygenase (HO-1) and DNA Damage Repair Molecules Using a 50 Hz Sinusoidal Electromagnetic Field (EMF).

Research RF Safe Research Library Jan 1, 2024

This in vitro study tested a 50 Hz, 1.3 mT sinusoidal electromagnetic field applied for 15 or 30 minutes to ARPE-19 retinal pigment epithelial cells and RGC-5 retinal ganglion cells. The authors report improved proliferative and migratory capacity after EMF exposure, alongside increased HO-1 and altered RNA…

Effect of extremely low frequency electromagnetic field on the pathogenicity of Magnaporthe oryzae.

Research RF Safe Research Library Jan 1, 2023

This laboratory study examined Magnaporthe oryzae pathogenicity under extremely low frequency electromagnetic field exposure (50 Hz, 3 mT). The authors report increased infection ability, growth rate, and conidia generation with ELF-EMF exposure. They also report increased tolerance to a cell wall-perturbing agent…

Effects of prolonged exposure to ELF-EMF on HERVs expression in human melanoma cells.

Research RF Safe Research Library Jan 1, 2022

This in vitro study examined whether 96-hour exposure to 50 Hz ELF-EMF affects expression of human endogenous retroviruses (HERV-H, HERV-K, HERV-W) in SK-MEL-37 human melanoma cells. Cells were continuously exposed at 1.5 or 3 mT and HERV env mRNA levels were measured by qPCR. The authors report significant…

Evaluation of the neuroprotective effects of Vitamin E on the rat substantia nigra neural cells exposed to electromagnetic field: An ultrastructural study.

Research RF Safe Research Library Jan 1, 2021

This rat study exposed animals to a 50 Hz, 3 mT electromagnetic field and assessed oxidative stress markers and substantia nigra ultrastructure. EMF exposure was associated with higher lipid peroxidation (MDA), lower SOD activity, and TEM-detected changes in nucleus/nuclear membrane and myelin sheath. Vitamin E…

Enhancement in the ATP level and antioxidant capacity of under continuous exposure to extremely low-frequency electromagnetic field for multiple generations.

Research RF Safe Research Library Jan 1, 2020

This multi-generation animal study exposed worms continuously to 50 Hz, 3 mT extremely low-frequency electromagnetic fields and assessed outcomes in the 15th generation. The study reports increased body length, higher ATP content and ATP synthase activity, and upregulated ATP-related gene expression in exposed worms.…

Lipidomic alteration and stress-defense mechanism of soil nematode Caenorhabditis elegans in response to extremely low-frequency electromagnetic field exposure.

Research RF Safe Research Library Jan 1, 2019

This animal (nematode) study exposed Caenorhabditis elegans to 50 Hz, 3 mT extremely low-frequency EMF and assessed multi-omics responses. The authors report significant lipidomic, proteomic, and transcriptomic alterations, including increased triacylglycerols. Pathway analyses suggest disrupted lipid metabolism,…

Combined effects of electromagnetic field and low-level laser increase proliferation and alter the morphology of human adipose tissue-derived mesenchymal stem cells.

Research RF Safe Research Library Jan 1, 2017

This in vitro study tested 50 Hz, 3 mT electromagnetic field (EMF) exposure and 808 nm low-level laser (LLL), alone and combined, on human adipose tissue-derived mesenchymal stem cells from six donors. The authors report increased cell numbers after 7 days with EMF, greater increases with LLL, and the largest…

Effect of extremely low frequency electromagnetic field on brain histopathology of Caspian Sea Cyprinus carpio.

Research RF Safe Research Library Jan 1, 2017

This animal study evaluated 50 Hz extremely low frequency electromagnetic field exposure and brain histopathology in Cyprinus carpio. Fish were sham-exposed or exposed to magnetic field intensities from 0.1 to 7 mT for 0.5 or 1 hour. The authors report severe brain histopathological changes at intensities ≥3 mT,…

[Influence of magnetic field on the growth of pathogen microorganisms isolated from the indoor environment at the Archivo Nacional de la República de Cuba].

Research RF Safe Research Library Jan 1, 2015

This in vitro study exposed five microorganisms (including indoor isolates and reference strains) to an extremely low frequency magnetic field (60 Hz, 3 mT) for two hours. The authors report a statistically significant increase in colony counts in exposed samples versus controls, with stronger stimulation in nutrient…

The effect of extremely low frequency pulsed electromagnetic field on in vitro fertilization success rate in N MRI mice.

Research RF Safe Research Library Jan 1, 2014

This randomized comparative animal study tested whether extremely low frequency pulsed electromagnetic field exposure affects IVF success in NMRI mice. Mice in the experimental group were exposed to a 1.3 mT pulsed field at 4 kHz for 5 hours during the IVF process. Although the exposed group showed a higher IVF…

Down-regulation of metallothionein 1 and 2 after exposure to electromagnetic field in mouse testis.

Research RF Safe Research Library Jan 1, 2011

This animal study examined mouse testis after 8 weeks of exposure to a 3 MT electromagnetic field (4 hours/day). The authors report significant histological changes (increased primary spermatocytes, increased Leydig cells, and increased basement membrane thickness) in exposed mice versus controls. MT1 and MT2…

Ultrastructural alterations and occurrence of apoptosis in developing follicles exposed to low frequency electromagnetic field in rat ovary.

Research RF Safe Research Library Jan 1, 2007

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…
