Jan 1, 2022
This in vitro study examined how low-frequency electromagnetic fields (LF-EMF) at different magnetic flux densities influence skeletal myogenesis in C2C12 cells. The authors report that 2.0 mT LF-EMF activated cells and increased PAX7, while 1.5 mT increased MyoD and myogenin expression. They conclude that different…

Jan 1, 2021
This in vitro study exposed mouse spermatogonial stem cells to 50 Hz EMF (2.5 mT; 1 h/day for 5 days) and assessed oxidative stress and cell health outcomes. The authors report increased ROS and apoptosis with reduced antioxidant (catalase) expression, viability, and colonization after EMF exposure. Sertoli…

This in vitro study exposed AGS human gastric cancer cells to 50 Hz ELF magnetic fields at 0.2 or 2 mT for 18 hours (continuous or intermittent). The authors report reduced cell viability versus control and up-regulation of miR-144 and miR-375 during exposure. They also report miR levels decreased 18 and 36 hours…

This study assessed pre-sowing sunflower seed treatments using vacuum, 5.28 MHz radio-frequency cold plasma, and an electromagnetic field for varying durations. The authors report faster germination with cold plasma (7 min) and EMF (15 min), while germination percentage was mostly unchanged except for a decrease…
Electromagnetic Field Could Protect SH-SY5Y Cells Against Cisplatin Cytotoxicity, But Not MCF-7 Cells.

Jan 1, 2018
This in vitro study exposed MCF-7 and SH-SY5Y cells to a 50 Hz, 0.50 mT electromagnetic field in combination with cisplatin and/or morphine. The combined "CDDP+Mor+EMF" condition showed higher cisplatin IC values than cisplatin alone and "CDDP+Mor" in both cell lines, consistent with reduced cisplatin cytotoxicity.…

Jan 1, 2017
This paper describes in situ EMF measurements around industrial high frequency (dielectric) welders, framed by Polish labor safety regulations aligned with EU Directive 2013/35/EU. It reports real-world scenarios where excessive EMF exposure can occur near welders, often linked to errors or omissions during…
