In vitro testing of several nosocomial strains (E. coli, Salmonella sofia, S. enteritidis, Proteus mirabilis, Pseudomonas aeruginosa) found that microwave exposure in a domestic microwave oven produced an efficient bactericidal effect in liquid cultures, comp…
In the presence of a 60 Hz, 0.1 mT magnetic field, PMA-stimulated rat peritoneal neutrophils showed a 12.4% increase in DCF fluorescence compared with paired measurements without the field (n=5; 18 pairs; P<0.02).
Pulse-modulated 915 MHz microwave exposure for up to 40 min had no effect on twitch rate or amplitude unless absorbed power was high enough to cause heating. Propranolol or atropine alone did not alter pacemaker or contractile function and showed no effect wh…
Whole-body EMFs with fundamental frequencies in the 0.25–2.0 kHz range were applied for 2 weeks in growing tail-suspended mice. Suspension altered structural, geometric, and material properties of long bones versus controls, and caloric restriction comparison…
In two baboons exposed to combined 60 Hz electric and magnetic fields with rapid onsets/offsets (with associated electric-field transients), profound reductions in nocturnal serum melatonin concentration were observed. The abstract contrasts this with prior p…
In erythropoietin-stimulated TF1 cells, PI3K activity increased (reported 34% within 2 min) and remained above basal for at least 20 min; pulsed EMF exposure decreased erythropoietin-stimulated PI3K activity to below basal levels and prevented membrane transl…
In analysis of a World War II-era worker study, statistically significant correlations were reported between increasing white blood cell count and average daily exposure, months of exposure, and total duration of EMF exposure from radars and high-frequency ra…
Exposure of human peripheral blood cultures to a 50 Hz, 5 mT electromagnetic field stimulated the cell cycle of dividing lymphocytes but did not change sister-chromatid exchange frequencies. Comparative tests with different exposure systems and culture temper…
Exposure to EMF at 24 or 14 MEGC with intensities of 400 or 200 V/m increased the number of rat hepatocytes with chromosomal aberrations by 1.4–1.5-fold. The response magnitude did not appear to change with increased field intensity at these frequencies; 100 …

Rats were exposed to low-level (1000 milli-Gauss) direct current EMF for 1 or 4 months. After 1 month, serotonin was elevated in the hypothalamus of male rats and the dopamine metabolite 3-methoxytyramine was increased in the corpus striatum of both sexes; af…
Exposure of B-lineage lymphoid cells to low energy electromagnetic fields stimulated Lyn and Syk protein tyrosine kinases, increased tyrosine phosphorylation of multiple substrates, and led to downstream activation of PKC. EMF-enhanced tyrosine phosphorylatio…
Exposure to 0.3 T (0.3 T/m gradient) and 0.7 T (0.7 T/m gradient) static magnetic fields had no effect on cell survival, while exposure to 6.34 T (no gradient) decreased cell survival. When combined with ionizing radiation, 0.3 T and 0.7 T exposures were asso…
After electric field pulsation, a small dye (propidium iodide) showed a long-lived permeabilized state. Uptake of 70 kDa FITC-dextran occurred only under drastic conditions and few cells that took up macromolecules remained viable; most dextran was trapped in…
Across two experiments, there was no evidence of work stoppage at 6 kV/m with 50 microT (0.5 G) or at 30 kV/m with 100 microT (1.0 G). No adverse effects of 60 Hz combined electric and magnetic field exposure were observed on MTS task performance.
In this prospective study of 2,967 pregnancies, EMF exposure during pregnancy (including electrically heated bed use) showed no important relation to low birth-weight or fetal growth retardation across multiple exposure windows. Results were consistent across…
Experimental data are reported on laboratory animals exposed to impulse-modulated microwave irradiation with discontinuous effects varying in intensity and exposure. Assessed outcomes included behavior, peripheral blood, biochemical, and morphologic parameter…

Microwave pulses in the 1–20 GHz range were generated by illuminating an Fe-compensated InP wafer with 50-ps optical pulses. Generation was monitored with a 40-GHz sampling oscilloscope, and saturation behavior, waveform evolution, and optical coupling effici…
An exposure facility was designed to generate 60 Hz vertical electric fields up to 65 kV/m and horizontal magnetic fields up to 100 microT. Mapping and operational data indicated the apparatus produced homogeneous, stable fields at desired intensities with ne…
High-intensity transcranial magnetic stimulation elicited bilateral forelimb extensor muscle responses in all animals with similar onset latencies on both sides. Lesioning/ablation of motor cortex and decerebration did not abolish responses, while a radiofreq…
In 4 male subjects, distinct middle-latency components of the auditory evoked magnetic field were observed at 11, 19, and 33 ms after a click stimulus. Equivalent current dipole sources for these components were localized to the supratemporal auditory cortex,…
