Microwave effects on acetylcholine-induced channels in cultured chick myotubes

During exposure to low-power microwaves, the frequency of ACh-activated single-channel openings decreased and the ACh-induced total current showed a faster falling phase. Channel open time and conductance were reported as not affected; the authors conclude mi…

Reduced exposure to microwave radiation by rats: frequency specific effects.

Rats reduced occupancy of a preferred cage side when occupancy triggered microwave exposure, resulting in reduced exposure. Avoidance/reduced exposure differed by frequency: 360 MHz and 2450 MHz at 1, 2, 6, and 10 W/kg were significantly different from 700 MH…

[K+,H+ and Cl- fluxes across erythrocyte membrane irradiated with radio frequency electromagnetic fields].

Exposure to 460 MHz microwave radiation (SAR 280 W/kg) produced the most significant changes in the K+ transport system of isolated rat erythrocytes, including increased K+ loss during treatment and a 2-fold decrease in the rate of K+ efflux under specified i…

Microwave effect on camphor binding to rat olfactory epithelium.

Microwave radiation decreased specific camphor binding to a membrane fraction of rat olfactory epithelium, but not to a Triton X-100 extract of the fraction. The inhibition did not depend on modulation frequency (1–100 Hz) and was not a linear function of SAR…

Morphological changes in cerebellum of neonatal rats exposed to 2.45 GHz microwaves.

Neonatal rats exposed to 2.45 GHz continuous-wave microwaves (10 mW/cm2; SAR 2 W/kg) showed nearly twice the number of small deeply stained pyknotic cells in the external granular layer compared with sham controls, along with altered Purkinje cell features (f…

Prenatal microwave exposure and behavior.

The studies reported results consistent with prenatal microwave exposure producing postnatal behavioral changes, particularly affecting sensitivity to thermally related stimuli or conditions rather than thermally neutral stimuli.

Influence of electromagnetic fields on the efflux of calcium ions from brain tissue in vitro: a three-model analysis consistent with the frequency response up to 510 Hz

Calcium-ion efflux from chicken brain tissues was examined across 1–510 Hz (15-Hz intervals) with 15 Vrms/m electric field and 59–69 nTrms magnetic field. Differences in mean efflux between exposed and sham samples did not show readily discernible frequency-r…

Some behavioral effects of short-term exposure of rats to 2.45 GHz microwave radiation.

Rats exposed to 2.45 GHz continuous-wave microwave radiation (10 mW/cm2 for 7 h) showed reduced locomotor activity and reduced responsiveness to repeated acoustic startle stimuli compared with sham-exposed animals. Microwave exposure had no effect on retentio…

[Effect of electromagnetic radiation of radio frequency (340 and 800 MHz) on liposomes from dimyristoyl lecithin].

In dimyristoyl lecithin liposomes prepared below the phase-transition temperature, annealing induced by 340- and 800-MHz microwave radiation required less integral heating than expected based on thermostat heating experiments.

Plasma corticosterone in hemorrhaged Japanese quail after microwave irradiation in ovo.

Hemorrhage increased plasma corticosterone in both sexes; shams had higher corticosterone than controls. In a separate experiment, eggs irradiated during incubation with 2.45 GHz continuous-wave microwaves produced juvenile males that had higher plasma cortic…

Serum enzymes in hemorrhaged Japanese quail after microwave irradiation during embryogeny.

Japanese quail eggs exposed in ovo to 2.45 GHz continuous wave microwaves (5 mW/cm2; SAR 4.03 mW/g) during the first 12 days of embryogeny showed no effects on lactate dehydrogenase, beta-glucuronidase, acid phosphatase, glucose, or protein either before or a…

Effect of radiofrequency radiation on mRNA expression in cultured rodent cells.

Across four rodent cell lines and the DNA probes used (oncogenes, heat shock protein, long terminal repeat sequences), no significant differences in mRNA expression were observed between microwave-exposed and sham-exposed samples.

B16 melanoma development in black mice exposed to low-level microwave radiation.

In black C57/6J mice with B16 melanoma, low-level 2,450 MHz microwave exposure (1 mW/cm2; SAR 1.2 mW/g) for up to 690 hours showed no significant effects on tumor development or survival compared with controls. No significant differences were observed between…

Studies of the induction of dominant lethals and translocations in male mice after chronic exposure to microwave radiation.

Male mice chronically exposed to 2.45 GHz continuous-wave microwaves (100 W m-2; SAR ~4 W/kg) showed no significant differences versus sham controls in pregnancy rate, preimplantation survival, or postimplantation survival. Cytogenetic analysis found no diffe…

Kinetics of channelized membrane ions in magnetic fields

A cyclotron resonance model for channel ion transport in weak magnetic fields was extended to include damping losses and used to derive conductivity tensors for different electric-field configurations. Model behavior near the cyclotron resonance frequency was…

In situ fixation of the spinal cord using microwave radiation.

The report states that microwave irradiation of the spinal cord before removal from the spine provides a rapid and easy method of tissue fixation, with an absence of artifacts comparable to perfusion fixation.
