Using a cDNA microarray of 97 target genes, seven genes showed increased transcription (reported fold-changes 2.07 to 3.68) after 2450 MHz simulated microwave exposure. No notably down-regulated genes were detected; the study also compared microwave exposure …

Several long-term exposure protocols produced statistically significant decreases in protection against hypoxic stress (continuous ELF; 30 or 60 min ELF twice daily; 30 or 60 min RF once daily). After 4 days of ELF exposure, HSP70 levels declined by 27% compa…
In lymphocyte cultures from 12 radiological workers, exposure to a 50 Hz pulsed magnetic field (triangular waveform; rise time ~1.2 ms; peak intensity 2.5 mT) was associated with a slight but statistically significant increase (p<0.05) in micronucleus frequen…
Post-ablation LF and HF were significantly decreased compared with pre-ablation values in both septal and free wall groups. In the free wall group, cumulative ablation energy correlated with delta HF (r=0.688, P=0.01) and delta LF (r=0.462, P<0.05). No signif…

Rabbit eyes exposed to microwave radiation at 5 mW/cm^2 or 10 mW/cm^2 for 3 hours showed inhibited gap junctional intercellular communication in lens epithelial cells, with stronger inhibition at 10 mW/cm^2. Connexin 43-positive staining decreased at 5 mW/cm^…
Rats exposed to a 50 Hz, 5 mT sinusoidal magnetic field showed significant differences in the cytoplasmic E-cadherin expression pattern in colon tissues compared with other groups. The authors interpret this as electromagnetic-field–related alterations in cel…
MF-1 cDNA sequence showed 100% homology with cytochrome oxidase subunit 1 (CO1). In HL-60, L1210 and CHL cells, exposure to 0.1 mT or 0.8 mT magnetic fields reduced CO1 transcription compared with controls after 20 minutes and after 24 hours (P<0.05).

After exposure conditions described, Cx43 labeling was reduced at intercellular junction regions and appeared more in the cytoplasm with aggregation near nuclei. Cytoplasmic Cx43 protein amount was increased in the ELF group (2.03 ± 0.89) and TPA group (2.43 …

Mice exposed to 50 Hz EMF (0.2 mT or 6.0 mT) for 2 weeks showed increased MDA in brain and liver and decreased T-AOC in brain and liver versus controls; GSH decreased in liver, and cell membrane fluidity decreased in brain and liver. Compared with 6.0 mT EMF …

In Drosophila embryos, 5-min exposure to non-modulated 460 MHz microwaves at 6 W/kg SAR with heating had an effect only slightly stronger at increased temperature (up to 40°C) than at normal temperature (24.5°C). Pulse-modulated exposure (6, 10, 16, 22 p.p.s.…

A 1-hour non-thermal 900 MHz GSM exposure altered the phosphorylation pattern of multiple proteins in EA.hy926 cells, including a transient increase in hsp27 phosphorylation. The hsp27 phosphorylation increase was prevented by the p38MAPK inhibitor SB203580, …
Exposure to microwaves at 37.5 GHz (8 mm) or 18.75 GHz (16 mm) at 0.2 mW/cm^2 induced changes in ENN during 15–60 s irradiation; ENN decreased in donors with elevated baseline ENN and increased in donors with low baseline ENN. No significant difference was fo…
Microwave radiation from mobile phones enhanced allergen-induced skin wheal responses (house dust mite and Japanese cedar pollen) but had no effect on histamine-induced wheal responses in patients with AEDS. Microwave radiation also increased plasma levels of…
Microwave exposure alone (2450 MHz, 5.0 mW/cm2 for 2 h) did not significantly increase comet length or micronucleated cell rates versus controls. MMC increased DNA damage and (at higher doses) micronucleated cell rates. Microwave pre-exposure followed by MMC …
In a double-blind laboratory perception task (100 V/m electric field; 6 microT magnetic field), 7/63 subjects achieved statistically significant performance suggesting a small EMF-sensitive subgroup. There was no relevant difference between self-reported EHS …
Most measured hematologic and immunologic parameters were similar between welders and controls. CD4 and CD8 levels were lower in welders (p<0.001 and p<0.05), and hematocrit was higher in welders (p<0.05), but differences were reported as not clinically signi…
Exposure to a 0.15 mT, 60 Hz sinusoidal EMF significantly protected HL-60, HL-60R, and Raji cells from heat-induced apoptosis after 12 h of exposure, and this protection persisted up to 48 h after EMF removal. EMF exposure for 24 h significantly decreased DNA…
Review of 24 epidemiological studies of residential ELF electric and magnetic field exposure and childhood leukemia found about half reported positive associations and half null. The authors note that positive studies had potential biases that could not be co…
In human amniotic fluid cells, 50 Hz 1 mT EMF alone showed no effect on PKC translocation. With co-exposure to TPA (10–100 nM), EMF produced a significant additive increase in PKC translocation and a small increase in total PKC activity versus TPA alone, whil…
In this rat model, EMF stimulation after orchiopexy was concluded to result in Leydig cell proliferation and increases in testosterone level and testis weight, but a decrease in germ cell population.
