After 8 h exposure, 0.50, 1.00, and 2.00 mW/cm2 groups showed decreased cell viability, increased cell condensation, inhibition of DNA synthesis, and significant G0/G1 arrest; 0.10 and 0.25 mW/cm2 showed no obvious changes. P27Kip1 protein expression increase…
Compared with controls, mice exposed to 2,450 MHz microwaves showed lower body weight at 5 and 15 mW/cm^2, pathological changes in thymus, higher CD8 expression at 5 and 15 mW/cm^2, lower G2+M phase thymocytes at 5 and 15 mW/cm^2, and higher thymocyte apoptos…

After high power microwave radiation, rats showed significantly reduced learning and memory performance. Hippocampal injury findings included rarefaction, edema, hemangiectasia, neuronal degeneration/necrosis, and decreased/disappearing Nissl bodies; apoptosi…

After 30 min exposure, ELF-EMF induced heat shock gene expression in HL-60 cells, particularly HSP70A, HSP70B, and HSP70C; induction was enhanced when combined with simultaneous heat shock (43°C for 30 min). Across 10–140 µT, even 10 µT significantly induced …
After sham exposure, pain and tolerance thresholds were unchanged, but they significantly decreased after 37 Hz EMF exposure (80 microT peak). Systolic blood pressure was significantly higher during EMF exposure; heart rate significantly decreased during both…
Mice exposed continuously to 60 Hz EMF (0.1 or 0.5 mT) for 8 weeks had no significant changes in body or testis weights, but showed increased incidence of germ cell death and fewer well-organized seminiferous tubules. TUNEL analysis found a significantly high…
Myoglobin solutions (pH 3.0) exposed for 3 h to a microwave electromagnetic field (SAR 51 +/- 1 mW/g) showed slower refolding kinetics of the heme binding site compared with non-exposed samples. The tryptophanyl lifetime distribution of exposed protein appear…
Cytochemistry results indicated a significant decrease in cytochrome oxidase activity compared with sham-exposed neurons after exposure for 2 hours/day (4 or 5 consecutive days) and after 12 hours exposure when immediately tested (P < 0.001). The authors repo…

Compared with sham-exposed animals, EMF-exposed rats showed an almost threefold increase in micronuclei in polychromatic erythrocytes in bone marrow after 30 days of exposure. Micronuclei induction was also observed in polymorphonuclear cells, and the increas…
In conductometric measurements at 25±0.05 °C, the stability constants for 18-crown-6 complexes with potassium ion in water decreased in the presence of a magnetic field. The authors also report that the magnetic field influenced the ion, solvent, and ligand.
Raman spectra before vs after exposure to a 50 Hz pulsed electric field showed no effect on covalent bonds but changes in secondary bonds (hydrogen and salt bonds). The analysis indicates destruction/weakening of insulin alpha-helix (amide I peak shift to hig…

In 10 dogs receiving RF catheter ablation, GAP-43(+) nerve fiber density increased at right atrium ablation sites at 2 hours and 1 month compared with controls, and robust sprouting was also observed at remote right atrium sites (>2 cm) in both timepoints. In…
Compared with controls, rats exposed to 900 MHz radiation for 10 days showed multiple skin histopathologic changes (e.g., increased stratum corneum thickness, epidermal atrophy, papillamatosis, basal cell proliferation, hypergranulosis, capillary proliferatio…
Leptospira cells exposed to a constant magnetic field (140±5 mT) showed lower densities and lower agglutination immunoreactivity compared with unexposed controls. Some exposed cells showed abnormal morphology (e.g., increased length).
AC electric field pulses estimated to produce at least 1 V across the cell membrane appeared more effective at producing cell lysis than fields producing lower membrane voltages. At membrane voltages above 1 V, higher frequencies (in the 10 kHz range) appeare…
Exponentially decaying electric field pulses produced substantial cell lysis/mortality across three cultured cell types. At 0.3 kV, murine spleenocytes showed ~50% mortality at 24 hours and ~25% viable cells at 48 hours. Other cell types showed mortality cons…
A mechanism based on Larmor precession theory is proposed, with the interaction target located in charged lipid groups emerging from the membrane surface. The results indicate that specific exposure conditions may enhance membrane permeability.
Among radar workers, semen quality and semi-clinical sperm injury varied with radar electromagnetic wave frequency, distance, intensity, duration, and shielding; a dose-response relationship was reported, with increased sperm dysmorphia described as a princip…

Compared with controls, apoptotic germ cells were significantly increased at 6 h, 24 h, and 48 h after 5 min exposure at 10 or 20 mW/cm2 (P<0.01), with a reported peak at 6 h after 10 mW/cm2. Other exposure/timepoint groups did not differ significantly from c…
