Egg lecithin multilamellar vesicles exposed to 900 MHz microwave radiation (SAR 12 ± 1 W/kg) for 5 h showed a dramatic decrease in optical anisotropy, interpreted as structural changes in acyl chain packing. IR and 1H NMR measurements indicated increased dama…
Whole blood samples exposed in vitro to continuous 1800 MHz microwave radiation (5, 10, 20 mW/cm^2 for 60–180 min) showed a statistically significant, though low, increase in micronucleus frequency dependent on exposure time and power density. Proliferation i…
In an experimental culture system, exposure of bovine eye lenses to a few mW at 1 GHz for over 36 h affected lens optical function, with macroscopic self-recovery when exposure was interrupted. Microscopic examination suggested effects persisted even after ma…
In rats exposed to S-band high power microwave radiation (mean power density ~2 to 90 mW/cm^2), exposures over 10 mW/cm^2 were associated with dose-dependent myocardial structural injury (r=0.968, P<0.05). beta1-AR expression increased on day 1 post-radiation…

In human epidermoid cancer KB cells, non-thermal MW-EMF exposure at 1.95 MHz induced time-dependent apoptosis (reported as 45% after 3 h). Exposure was associated with decreased ras and Raf-1 expression and reduced ras/Erk-1/2 activity, increased ubiquitinati…
Exposure to 0.5–1.0 mT, 50-Hz ELF-EMF for 24–72 h induced a dose-dependent increase in proliferation (~30% increase after 72 h at 1.0 mT) and increased S-phase percentage. DNA damage increased dose-dependently (strand breaks and 8-OHdG), with peaks at 24 and …
Rats exposed to ELF-EMF (50 Hz, 0.97 mT) had significantly higher 8OHdG levels in DNA than sham controls at both 50 and 100 days (p<0.001 for both). Plasma TBARS levels were also higher in the exposed group at both time points (p<0.001), and the extent of DNA…
Stereological analysis of thyroid sections showed increased volume density of degranulated mast cells in all groups after ELF-EMF exposure and during the off-field period. Numerical density was also increased in all groups except group III.
Among elderly women with mammary tumors, a higher proportion in the later period (1991–2003) were reported as regularly exposed to EMF for at least 3 hours/day compared with the earlier period (1978–1990) (51.1% vs 19.5%; chi2=57.2, p<0.001). The authors repo…
In rats exposed to 900 MHz EMF, serum TSH and T3/T4 levels were significantly lower than in sham-exposed rats (p<0.01). No statistically significant differences were observed between control and sham-exposed groups (p>0.05).
Compared with sham exposure, GluR2 protein in exposed neurons was significantly down-regulated (P<0.01) and intracellular calcium ions were significantly up-regulated (P<0.01). The authors report trends consistent with a dose-response relationship across SAR …

Intermittent 50 Hz ELF-EMF exposure at 1 mT produced a time-dependent increase in micronuclei, becoming significant after 10 h and reaching about three times basal levels after ~15 h. Chromosomal aberrations were reported to increase up to 10-fold above basal…
Rats exposed to ELF-EMF (50 Hz; 100–300 microT; 54–160 V/m) showed a significantly increased number of serotonin-positive mast cells in the skin and increased NPY-containing nerve fibers in the thyroid compared with controls.
Using an EPR spectroscopy setup comparing exposed vs control capillary samples, the authors report that application of static or pulsed magnetic fields decreased the reaction rate of the Fremy’s salt–ascorbic acid radical reaction.
A magneto-hydrodynamics model suggested that ultrahigh static magnetic fields could reduce blood volume flow rate in the human aorta by more than 10%, which the authors propose may lead to an anoxia condition of acute ischemia. Using an ionic-based ventricula…
Compared with controls, rats exposed to PEMF showed a dose-dependent decrease in the surface of c-Kit immunopositive cells in the duodenum and colon, alongside increased expression of pro-apoptotic Bax protein in c-Kit immunopositive myenteric cells. The auth…
Compared with control, all 50 Hz magnetic field exposure groups (0.097 T; 5–120 min) showed higher Bax and Caspase-3 expression and lower Bcl-2 expression by flow cytometry, immunocytochemical staining, and Western blot.
SNU cells and human peripheral blood lymphocytes showed increased intracellular calcium-ion concentration after exposure to a 50 Hz homogeneous ferromagnetic field (0.097 T) across different exposure time periods.
In experiments exposing human blood monocyte and thrombocyte cell populations to 1800 MHz continuous-wave microwave radiation at a power level described as low enough to be considered athermal, microwave irradiation was reported to favor a decrease in cell me…
Rats were exposed to fields from high-voltage transmission lines (4000 V/m and 0.09–0.1 G) for about 400 days. The authors report differences in phospho-STAT3 expression and that FT-IR spectra of G-proteins differed between exposed and control groups, interpr…
