[The activity of prooxidant-antioxidant system in loach embryos under the action of microwave radiation].

Research RF Safe Research Library Jan 1, 2014

This animal study examined oxidative stress and antioxidant defenses in loach embryos exposed to GSM 900 MHz microwave radiation (SAR 1.1 W/kg) for 1–20 minutes during early embryogenesis. The authors report significant changes in lipid peroxidation products and altered antioxidant enzyme activities. They conclude…

Modification of catalase and MAPK in Vicia faba cultivated in soil with high natural radioactivity and treated with a static magnetic field.

Research RF Safe Research Library Jan 1, 2014

This plant study examined effects of a 30 mT static magnetic field and cultivation in soil with high natural radioactivity on oxidative stress-related markers in Vicia faba. The abstract reports significant changes in catalase and MAPK gene expression in treated plants versus controls. Catalase activity and H2O2…

Reactive oxygen species elevation and recovery in Drosophila bodies and ovaries following short-term and long-term exposure to DECT base EMF.

Research RF Safe Research Library Jan 1, 2014

This animal study measured ROS in Drosophila bodies and ovaries after short- and long-term exposure to DECT base RF (1.88–1.90 GHz; SAR 0.009 W/kg). The abstract reports increased ROS in bodies after 6 h exposure and in ovaries after 0.5–1 h exposure, with apparent saturation under longer continuous exposure. It also…

Assessing of plasma protein denaturation induced by exposure to cadmium, electromagnetic fields and their combined actions on rat.

Research RF Safe Research Library Jan 1, 2014

This animal study examined whether cadmium, EMF exposure, or their combination affects oxidative damage and protein structure in rat plasma. The authors report increased oxidative protein damage markers and changes in protein-related measures after cadmium and/or EMF exposure. Effects were described as more…

Electromagnetic fields act via activation of voltage-gated calcium channels to produce beneficial or adverse effects

Research RF Safe Research Library Jan 1, 2013

This narrative review argues that non-thermal biological effects of extremely low and microwave frequency EMFs may be mediated by activation of voltage-gated calcium channels (VGCCs). It cites 23 studies in which VGCC blockers reportedly block or reduce diverse EMF effects and proposes downstream…

Critical time delay of the pineal melatonin rhythm in humans due to weak electromagnetic exposure.

Research RF Safe Research Library Jan 1, 2013

This paper discusses a mechanism by which weak electromagnetic exposure could perturb radical pair recombination rates, potentially increasing radical lifetimes. It reports significant melatonin interruption and circadian rhythm changes due to perturbation of chemical reaction rates, and notes that mRNA degradation…

The Effects of Cell Phone Waves (900 MHz-GSM Band) on Sperm Parameters and Total Antioxidant Capacity in Rats.

Research RF Safe Research Library Jan 1, 2013

This experimental study exposed adult male Wistar rats to 900 MHz GSM-band cell phone-related waves for 2 or 3 weeks and assessed sperm parameters and total antioxidant capacity. All exposure groups showed significantly reduced sperm viability, motility, and total antioxidant capacity compared with controls.…

Microwave radiation induced oxidative stress, cognitive impairment and inflammation in brain of Fischer rats.

Research RF Safe Research Library Jan 1, 2012

This animal study exposed male Fischer-344 rats to 900 MHz or 1800 MHz microwave radiation for 30 days (2 h/day) and compared outcomes to sham exposure. The authors report significant cognitive impairment along with increased oxidative stress in brain tissue in exposed rats. They also report increased inflammatory…

Effects of extremely low frequency magnetic field on oxidative balance in brain of rats.

Research RF Safe Research Library Jan 1, 2011

This animal study examined whether an extremely low frequency magnetic field (7 mT, 40 Hz) used in magnetotherapy alters oxidative balance in rat brain after 10 days of exposure. The 30 min/day exposure condition was associated with increased lipid peroxidation, while the 60 min/day condition was associated with…

[Effects of 50 Hz sinusoidal magnetic field on Ca2+ release channel ryanodine receptor of sarcoplasmic reticulum vesicles].

Research RF Safe Research Library Jan 1, 2009

This in vitro study examined whether a 50 Hz sinusoidal magnetic field affects the sarcoplasmic reticulum calcium release channel RyR1. A 0.4 mT exposure for 30 minutes increased SR Ca2+ release rate and [(3)H]-ryanodine binding under NADH/NAD+ conditions. The authors also report increased NADH oxidation and…

Effects of electromagnetic field produced by mobile phones on the oxidant and antioxidant status of rats.

Research RF Safe Research Library Jan 1, 2007

This rat study examined whether EMR from GSM mobile phones affects oxidant/antioxidant status. Compared with controls, exposed rats had lower plasma antioxidant vitamins (C, E, A), reduced glutathione, and lower CAT and SOD activities. The acute exposure condition was reported to produce larger decreases than the…

900 MHz radiofrequency-induced histopathologic changes and oxidative stress in rat endometrium: protection by vitamins E and C.

Research RF Safe Research Library Jan 1, 2007

This rat study examined 900 MHz radiofrequency exposure (30 min/day for 30 days) and reported biochemical and histopathologic changes in endometrial tissue consistent with oxidative stress and tissue injury. The abstract reports increased NO and MDA and decreased antioxidant enzyme activities (SOD, CAT, GSH-Px) in…
