Male Wistar rats exposed for 35 days to low-intensity microwave radiation at 2.45 GHz (SAR 1.0 W/kg) or 16.5 GHz (SAR 2.01 W/kg) showed a statistically significant increase (p<0.001) in DNA single strand breaks in brain cells compared with controls, measured …
Rats exposed to 1800 MHz CW RF at 0.5 or 1.0 mW/cm^2 for 12 h/day for 21 days showed significantly lower NR2A and/or NR2B immunoreactivity in specific hippocampal regions versus sham controls. Decreases were reported for NR2A in CA3 at 0.5 mW/cm^2 and in CA1 …

Rats exposed to high power microwave radiation at 3–100 mW/cm2 for 5 minutes showed pathological injury to testicular spermatogenic cells, including degeneration, necrosis, shedding of spermatogenic cells, multinuclear giant cells, decreased/lost sperm, and i…

Compared with controls, EMF-exposed rats had higher TBARS in plasma and brain tissue and lower GSH in brain and erythrocytes. Zinc-supplemented EMF-exposed rats had lower TBARS and higher GSH than EMF-only rats, and higher plasma zinc levels.
Barley seedlings grown for 5–6 days under static magnetic and 50 Hz electromagnetic fields tuned to Ca2+ ion cyclotron resonance had 15–20% shorter shoots and 10–12% lower weight than controls grown under normal geomagnetic conditions. Exposed plants showed d…
In cultured rat cortex and hippocampus neurons exposed to 1.8 GHz RF EMF (217 Hz modulation) at SAR 2 W/kg for 24 hours, 34 of 1200 candidate genes were reported as up- or down-regulated. Map2 expression was statistically significantly up-regulated after RF E…

NK cell cytotoxic activity of splenocytes was decreased in guinea pigs exposed to a 50 Hz, 2 mT magnetic field compared with controls.
No differences were observed in transition percentages from larvae to pupae or pupae to adults (p>0.05). Mean pupation time was delayed linearly with increasing exposure duration (p<0.05). In the discontinuous 3 h + 3 h exposure group, mean offspring number w…
Compared with controls, the exposed group had a significantly higher relative risk of decreased HRV (STD R-R < 27 ms; OR = 2.8). VLF power spectrum was significantly higher in the exposed group and correlated with exposure level. The proportion with dominant …
Rats exposed to a 50 Hz EMF (100–300 microT, 54–160 V/m) showed predominance of microfollicles with less colloid and dilated blood capillaries versus controls. Stereological counting found significant increases in volume density of follicular epithelium, inte…
Thirty rat pups exposed to 50 Hz EMF during in utero development and postnatal life showed disruption of the boundary tissue of seminiferous tubules at various layers, including infoldings and thinning/stripping of the outer non-cellular layer with a "blister…
Pregnant rats were exposed to a 60 Hz, 3 microT magnetic field for 2 h/day during pregnancy and/or fed a regional basic diet. The association of EMF exposure with the deficient diet was reported to delay all assessed offspring reflexes compared with the casei…
Rats exposed to 900 MHz EMF (30 min/day for 30 days) showed increased malondialdehyde levels in endometrial tissue and evidence of apoptosis. In the vitamin E+C treated exposed group, oxidative tissue injury and apoptosis were reported as ameliorated compared…
After stereotactic pulsed RF application, electron microscopy showed intracytoplasmic edema, clearer mitochondrial cristae, and openings in cell membrane pores. These findings were more prominent in the conventional RF group; light microscopy reported 5.5% af…
Twelve women exposed at home to EMFs from radio-television broadcasting stations (balcony mean field 4.3±1.4 V/m in 2000; 3.7±1.3 V/m in 2005; nearby area <2.0 V/m) showed in 2000 reduced blood NK lymphocytes, reduced PHA-stimulated PBMC proliferation, and re…
The article argues that available evidence demonstrates an ongoing risk that electromagnetic interference from cell phones can affect medical devices, and discusses how newer communications technologies (cordless phones, microcell systems, VoIP phones) may im…
A liver rupture occurred after radiofrequency ablation of relapsing hepatocellular carcinoma, associated with major thermoablation in the hepatic venous region and contributing incomplete hepatic venous outflow thrombosis. Surgical revision with liver tampona…

After 5 minutes of electric field treatment (0.5 to 6.0 kV·cm(-1)), the relative contents of alpha-helix, beta-sheet, beta-turn, and random coil in lipase changed in a non-monotonous manner with increasing field strength. Overall, electric field treatment ten…

Experimental measurements indicated that temperature probe positioning affects measured lead-tip temperature and local SAR during MRI RF exposure. Transversal contact between the active portion of the fluoroptic probe and the lead tip produced the highest mea…
In vitro experiments on mouse ascitic tumor cells reported that synchronous application of microsecond-range electric fields (1–7 kV/cm) and shock waves (pressure up to 100 MPa) increased the efficiency of forming irreversible membrane pores compared with non…
