Real-time measurements showed increased cytosolic Ca(2+) and increased Ca(2+) spiking in response to nonthermal RF exposure from 700–1100 MHz. Example given: 800 MHz at 0.5 W/kg increased spikes to 15.7±0.8 vs ~5 spikes/cell/60 min in controls (P<0.05). The increase depended on frequency but not on SAR between 0.5–5 W/kg; pharmacological agents implicated N-type Ca(2+) channels and phospholipase C, and microfilament disruption prevented Ca(2+) spikes.

Chromaffin cells exposed to nanosecond electric pulses (2–8 MV/m) showed a rapid, short-lived increase in intracellular calcium after a single 4 ns, 8 MV/m pulse, with response magnitude dependent on field intensity. The calcium rise was unaffected by depletion of intracellular stores (caffeine or thapsigargin) but was prevented by extracellular EGTA, Co2+, or the L-type calcium channel blocker nitrendipine, consistent with calcium entry via L-type channels.

Exposure to 450 MHz pulse-modulated microwaves increased average EEG alpha power (17%) and beta power (7%), while theta rhythm was unaffected. Statistically significant increases in alpha and beta power occurred during the first 30 s of exposure at modulation frequencies of 14 and 21 Hz; no enhancement was reported at 7 Hz modulation. Individual sensitivity varied, with statistically significant beta increases reported in four subjects.

Chronic non-thermal exposure to 1 kHz square wave-modulated 2450 MHz microwave radiation (2 h/day for 21 days) was associated with significant changes in several measured pathophysiological parameters (p<0.05 or better), except body temperature, grooming behavior, and TSH. An artificial neural network classified EEG power spectra with an average agreement of 71.93% for exposed rats versus 93.13% for controls; the lower agreement in exposed animals was interpreted as suggesting only mild effects under this setup.

Using 109 weekly exposimeter measurements, differences between a naïve substitution approach and robust regression on order statistics (ROS) were moderate for total RF-EMF exposure (90th percentile and arithmetic mean). For minor RF-EMF sources, the naïve approach considerably overestimated exposure contributions, leading to an underestimation of the exposure range and potential bias in exposure-response evaluations; robust ROS was concluded to be more reliable, though source-specific medians/lower percentiles depend on distributional assumptions.

Osteogenesis microarray analysis identified 19 differentially expressed genes between EMF-stimulated MSCs and controls (6 up-regulated, 13 down-regulated). Semi-quantitative RT-PCR confirmed increased Bmp1 and Bmp7 mRNA and decreased Egf and Egfr mRNA in the EMF-stimulated group (P<0.05).

Exposure to low level 900 MHz EMF was associated with a rapid drop in ATP concentration (27% after 30 min) and an 18% decrease in adenylate energy charge (AEC). The authors discuss a possible signalling role for extracellular ATP in plant stress physiology in the context of EMF exposure.

HUVEC cultures exposed to a sinusoidal 1 mT, 50 Hz EMF for up to 12 h showed increased endothelial cell proliferation and tubule formation and accelerated wound healing. EMF exposure was associated with major reorganization of cytoskeletal fibres and focal adhesion complexes, and increased phosphorylation and overall expression of VEGF receptor 2 (KDR/Flk-1).
