Cell cultures exposed to a GSM-simulated 960 MHz field in a TEM cell showed a significant change in cell proliferation compared with non-exposed controls at both 39°C and 35±0.1°C. Sham-exposed cells under the same temperature conditions showed no significant…
Staphylococcus aureus on stainless steel discs exposed to 2450 MHz microwave radiation (up to 800 W) showed reduced viability with increasing exposure time, with complete inactivation at 110 s when temperature reached 61.4 b0C. The report concludes the killin…
Compared to controls, occupationally exposed subjects showed an increased frequency of micronuclei and disturbances in the distribution of cells across the first, second, and third mitotic divisions.
CBA mice exposed outdoors to 50 Hz EMF (~8 microT rms) from a 220 kV transmission line showed a highly significant change in comet assay tail/head ratio after 32 days (p<0.001), interpreted as DNA damage in brain cells. A decreased number of mononuclear leuko…
Cytologic investigations identified sensitive blood-system indices during EMF exposure, including disorders of megakaryocyte differentiation and nonspecific reactions. The abstract reports threshold-like intensity levels: effects at allowable levels were desc…

Roots grown in microgravity had higher growth rates than ground controls. Immediately upon application of an applied electric field, root elongation was inhibited in microgravity-grown roots.
Among workers at a retransmission TV center and a satellite communications center, increased IgG and IgA concentrations and decreased lymphocyte and T8 cell counts were reported. Among radar operators, IgM concentration was elevated and total T8 cell count de…

Two-step exposure effects depended on the time interval between exposures and pulse duration. The biologically active dose of microwave radiation was reported to be much lower than that of infrared laser radiation, while laser radiation induced a stronger cel…

In irradiated rats, peripheral blood results suggested a decreasing tendency in total leukocyte count and relative lymphocyte count. Slight increases were observed in granulocyte count and in absolute peripheral blood erythrocyte count compared with controls.
Whole-body microwave sinusoidal irradiation (8.15–18 GHz; power density 1 µW/cm²) significantly enhanced TNF production in peritoneal macrophages and splenic T lymphocytes and facilitated T-cell proliferation in response to mitogenic stimulation. Exposure for…
In 18 healthy subjects, sleep during exposure to a 50 Hz/1 µT electrical field was associated with reduced total sleep time, sleep efficiency, stages 3+4 slow wave sleep, and slow wave activity compared with no exposure. Circulating melatonin, growth hormone,…
Exposure to sinusoidal ELF-EMF (7–8 mT, 20 Hz) for 60 min increased PKA activity in human skin fibroblasts (~2-fold) and rat embryonic osteoblasts (~1.7-fold). With long-term exposure up to 7 days (1 h-on/1 h-off), PKA activity showed transient stimulation du…
Flow cytometry showed CD surface marker expression was weakly influenced overall, with no differences between exposed and non-exposed cells for several markers. Evidence of CD4 protein production was reported in lymphocytes exposed to ELF-EMF (immunofluoresce…
EMF exposure affected plasma melatonin in male kestrels, with suppression at 42 days and elevation at 70 days of exposure, suggesting a seasonal phase-shift in the melatonin profile. Melatonin was suppressed in long-term fledglings but not in short-term fledg…
CD4+ cell surface receptor expression measured by FACScan was not statistically significantly different between ELF-EMF exposed and unexposed PBMC at 24, 48, and 72 h, though a slight difference in bound antibody distribution was noted at 24 and 72 h. CD4+ DN…
The paper discusses uncertainty in hazard identification for 50 60 Hz electric and magnetic fields and cancer, emphasizing how to synthesize epidemiological, experimental, and background information. It notes that epidemiological studies show a somewhat consi…
Across both groups, the only cognitive test affected was choice reaction time, which decreased (faster responses) during exposure conditions; effects were stronger in the analogue simulation and less in the digital simulation. No changes were observed in word…
After 24 h of culture following exposure, the 0.5 T static magnetic field reduced CD69 expression in PBMC in vitro; this reduction was enhanced after PHA stimulation. IFN-gamma and IL-4 release increased, but these increases were reduced after PHA stimulation…
Compared with normal geomagnetic conditions, epicotyl elongation was promoted under low magnetic field (LMF), most prominently in the middle part of the epicotyl. Epidermal cells exposed to LMF showed cell elongation and increased osmotic pressure of cell sap…
A theoretical analysis suggests a magnetic field can affect single-bubble sonoluminescence in water by altering bubble dynamics via Lorentz-force torque on moving water molecules’ electrical dipole moments, transforming some kinetic energy into heat. The magn…
