After 45 min exposure to pulsed 2450 MHz microwaves (1 mW/cm2; average whole-body SAR 0.6 W/kg), rats showed retarded learning in the radial-arm maze, interpreted as a deficit in spatial working memory. The behavioral deficit was reversed by pretreatment with…
Microwave exposure for 90 seconds was reported to provide rapid sterilization of scalpel blades contaminated with Candida albicans. SEM analysis indicated microwave irradiation induced time-dependent morphological modifications, with greater alterations at lo…
Rats exposed to 2.45 GHz microwave radiation at 80 mW/cm2 (CW) producing a 2.2°C rectal temperature increase showed a 48.5% decrease in canalicular membrane Mg(++)-ATPase activity (Vmax) and a 170% increase in Na+/K(+)-ATPase activity (Vmax) versus control; n…
Albumin leakage was observed in 5/62 controls and 56/184 rats exposed to 915 MHz microwaves. Continuous wave exposure produced 14/35 positive findings, reported as significantly different from controls (P = 0.002).
In an in situ Tradescantia-micronucleus bioassay, higher micronucleus (MCN) frequencies than laboratory controls were observed at exposure sites in the immediate vicinity of broadcasting antennae (10–21 MHz), where IRPA electric field strength standards were …
After 120 min of 2.45 GHz microwave exposure (6 mW/g), PNPA diffusion through the liposome lipid bilayer increased about twofold compared with temperature controls, with a time-dependent effect. Enzyme activity increased over 120 min (22.3% to 80%), and highe…
Mice exposed chronically to 2.45 GHz CW microwaves at 10 mW/cm2 (SAR 6.8 W/kg) had a significantly shorter average life span than sham-exposed controls (572 vs 706 days; P=.049; truncation >20%). Mice exposed at 3 mW/cm2 (SAR 2.0 W/kg) had a slightly but not …
Microwave exposure generally did not alter NSA or NR in mice pretreated with lower doses of chlordiazepoxide (8 or 16 mg/kg). In mice pretreated with 32 mg/kg chlordiazepoxide, exposure to 36 W/kg microwave radiation significantly reversed reductions in NSA a…
Sinusoidal EMF exposure at 50 Hz and 100–2000 microT (rms) showed no significant effects on tracer uptake, [Ca2+]i, pHi, or TMP in the tested cell types. EMF exposure at estimated cyclotron magnetic resonance frequencies (20–1200 microT rms) also showed no si…
Ten subjects exposed to a 10 Hz, 1 gauss electromagnetic field for 10 minutes showed significantly reduced 10 Hz brain electrical activity at occipital electrodes during the 1-minute interval after exposure compared with control values from the same subjects.
In 19 subjects exposed to 1.5- and 10-Hz EMFs (0.2–0.4 gauss) in 2-second epochs, spectral analysis of EEG indicated altered brain electrical activity at the frequency of the applied EMF during stimulation.
In a pretest-posttest evaluation of a brochure communicating EMF health risks, respondents’ naive beliefs about the potential for EMF exposure to cause harm were highly influenced by specific content elements of the brochure.
In DMH-initiated mice, tumor incidence did not significantly differ among DMH-only, DMH+microwave, and DMH+TPA groups (P > 0.25). No differences were found between DMH-only and DMH+microwave groups for tumor incidence and other reported tumor measures (P > 0.…
Using a kinetics vessel at steady-state temperatures of 90, 100, and 110°C, inactivation rates for microwave-heated and conventionally heated spores were similar at the 95% confidence level. In a cooled-loop setup absorbing ~400 W microwave power, inactivatio…
In unilamellar phosphatidylcholine liposomes exposed at 37.6 ± 0.5 °C, 2.45 GHz microwave exposure did not produce a non-thermal increase in permeability beyond that seen with thermal heating for the same 5–20 min intervals. The authors conclude that previous…
Murine peritoneal exudate cells exposed to 60 Hz electric field (300 V/in.), magnetic field (0.3 mT), or combined fields showed no statistically detectable changes in IL-1 alpha after 24 hours or IL-6 after 48 hours compared with controls (one-way ANOVA).
Using the single cell gel assay, the EMF exposure system used in this study appeared to have no direct effect on DNA single strand break/DNA damage induction across a series of experiments. EMF also did not significantly potentiate DNA damage in cells treated…
Repeated exposures to 50 Hz magnetic fields at 10 mT (professional/therapeutic device-related) or 6 µT (environmental level) showed no significant alterations in avian or mammalian embryogenesis. No significant differences were found with different field vect…
The abstract poses hypotheses/questions about whether short-term non-ionising electromagnetic radiation exposure could stimulate the anterior pituitary and gonads, and whether long-term microwave exposure could cause adenoma and carcinoma. It states that more…
The paper proposes a mechanism in which transit time effects of ionic transport carriers make a biological membrane behave like a dielectric diode, with conductivity and dielectric permittivity dependent on transit angles, leading to additional microwave abso…
