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…

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.

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…

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.…

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…

Jan 1, 2012
This in vitro study tested whether 900 MHz GSM mobile phone radiation affects ferritin measurements in human serum wells. Exposed wells (30 minutes, speech-mode phone) showed a statistically significant decrease in ferritin compared with unexposed controls. The authors propose RF exposure may influence…
Effects of extremely low frequency magnetic field on oxidative balance in brain of rats.

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…

Jan 1, 2009
This review discusses the comet assay and summarizes research on non-ionizing EMF exposure and DNA/chromosomal damage. It describes both positive and negative findings across studies, noting no consistent overall pattern for radiofrequency radiation (RFR). The authors nonetheless conclude that under certain exposure…
The influence of low-frequency magnetic field on plasma antioxidant capacity and heart rate.

Jan 1, 2009
This animal study exposed Sprague-Dawley rats to a 40 Hz, 7 mT time-variable magnetic field and measured ECG heart rate and plasma antioxidant capacity before and after exposure, including after 14 days. The authors report a significant decrease in heart rate after 14 days. Antioxidant defence findings were mixed,…
Effects of electromagnetic field produced by mobile phones on the oxidant and antioxidant status of rats.

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

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…

Jan 1, 2007
This paper reports observations in northern inhabitants relating geomagnetic conditions to circadian rhythm patterns in saliva total antioxidant capacity. It states that the amplitude of the circadian rhythm decreases during both increased geomagnetic activity and magnetic calm, with the most favorable rhythm display…
