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…

Effect of Extremely Low Frequency Electromagnetic Field and GABAA Receptors on Serum Testosterone Level of Male Rats.

RF Safe Research Library Jan 1, 2013 REASSURANCE MEDIUM

This animal experiment tested whether extremely low frequency electromagnetic field (ELF-EMF) exposure interacts with GABAA receptor modulation to affect serum testosterone in male rats. Rats were exposed for 30 days (8 hours/day) or sham exposed, then given saline, a GABAA antagonist…

[Modulation of Ca(2+)-dependent proteinase activity in invertebrates and fish under the action of weak low-frequency magnetic fields].

RF Safe Research Library Jan 1, 2013 CONCERN MEDIUM

This study examined whether weak low-frequency magnetic fields affect Ca2+-dependent proteinases (calpains) in fish and invertebrates using in vivo and in vitro experiments. The authors report a significant decrease in calpain activity in animals exposed to a field tuned to Ca2+ parametric…

A preliminary examination of cell phone use and helping behavior.

RF Safe Research Library Jan 1, 2013 CONCERN MEDIUM

This preliminary study examined whether talking on a cell phone is associated with reduced helping behavior in a staged situation. Among 62 participants, those talking on a cell phone were less likely to offer help to a confederate who dropped magazines than those not talking on a phone. The…

Effect of puerarin on matrix metalloproteinase-2 in human fetal scleral fibroblasts treated with low frequency electromagnetic fields.

RF Safe Research Library Jan 1, 2013 CONCERN MEDIUM

This in vitro study examined whether extremely low frequency electromagnetic field (ELF-EMF) exposure alters MMP-2 expression in cultured human fetal scleral fibroblasts and whether puerarin modifies this response. The authors report increased MMP-2 mRNA and protein expression after 0.2 mT ELF-EMF…

Study on effective improvement of mobile phone sound quality in a noise environment for the hearing-impaired.

RF Safe Research Library Jan 1, 2013 NEUTRAL UNKNOWN

This study evaluated whether the NAL-NL1 hearing-aid fitting formula is appropriate for hearing-impaired mobile communication, comparing it with a modified fitting formula. Speech materials were low-pass filtered at 8 kHz and presented through a mobile phone for word-recognition testing in quiet…

P-selectin expression in a colon tumor model exposed by sinusoidal electromagnetic fields.

RF Safe Research Library Jan 1, 2013 REASSURANCE MEDIUM

This animal study evaluated whether sinusoidal magnetic field exposure alters P-selectin expression in a rat colon tumor model. Rats exposed to 50 Hz, 5 mT for 6 h/day for 8 months showed no statistically significant change in P-selectin expression by immunohistochemistry. The authors indicate…

[Magnetic field numerical calculation and analysis for magnetic coupling of centrifugal blood pump for extracorporeal circulation].

RF Safe Research Library Jan 1, 2013 NEUTRAL UNKNOWN

This engineering paper models the driving system of a centrifugal blood pump for extracorporeal circulation, focusing on disc magnetic coupling. It uses a three-dimensional static magnetic field edge element method in Ansys to numerically calculate magnetic fields and analyze how coupling…

Effectiveness of mobile phone messaging in prevention of type 2 diabetes by lifestyle modification in men in India: a prospective, parallel-group, randomised controlled trial.

RF Safe Research Library Jan 1, 2013 NEUTRAL MEDIUM

This prospective, parallel-group randomized controlled trial tested whether frequent mobile phone messaging could support lifestyle modification to prevent type 2 diabetes in high-risk Indian men. The intervention group had a lower incidence of type 2 diabetes than the control group receiving…

Specific absorption rate variation in a brain phantom due to exposure by a 3G mobile phone: problems in dosimetry.

RF Safe Research Library Jan 1, 2013 NEUTRAL MEDIUM

This paper describes a SAR measurement system for a 3G mobile phone (1718.5 MHz) using brain phantom material in a Perspex box sized to a small rat volume, with induced fields measured at multiple locations. SAR was computed from induced-field measurements and also estimated experimentally via…

Cell phone usage and erectile function.
