Two thermophilic enzymes (S-adenosylhomocysteine hydrolase and 5'-methylthioadenosine phosphorylase) exposed to 10.4 GHz microwave radiation showed non-thermal, irreversible, time-dependent inactivation. The inactivation rate was related to absorbed energy an…
Effects of low-intensity AC and/or DC electromagnetic fields on cell attachment and induction of apoptosis.
Rat tendon fibroblast and rat bone marrow osteoprogenitor cells exposed in vitro to AC (60 or 1000 Hz, up to 0.25 mT peak-to-peak) and/or DC (up to 0.25 mT) magnetic fields showed extensive detachment of preattached cells and impaired attachment of previously…
Amyotrophic lateral sclerosis and occupational exposure to electromagnetic fields.
Occupational EMF exposure was classified (low to high) and summarized as total (E1) and average (E2) exposure indices. Among participants with ≥20 years of work experience, odds ratios comparing the 75th percentile of case exposure (vs minimum exposure) were …
Exposure to a 50 Hz electromagnetic field induces activation of the Epstein-Barr virus genome in latently infected human lymphoid cells.
Exposure of Akata cells latently infected with EBV to a 50 Hz electromagnetic field increased the number of cells expressing EBV early antigens.
Biological effects of continuous exposure of embryos and young chickens to electromagnetic fields emitted by video display units.
Across three independent experiments, constant exposure to EMFs emitted by video display units (TV or computer) was associated with significantly increased fetal loss (47–68%) compared with sham exposure (10–33%). Exposed young chickens also showed markedly d…
Reverse-micelle model: pH, electromagnetic field and inhibitor enzyme interaction.
In an AOT reverse-micelle model, low-intensity microwave-field perturbation produced a similar inhibitory effect on enzyme reactions as observed in dilute-solution reactions, though interactions between physical (microwave) and chemical perturbants were diffe…
Effect of extremely low frequency (ELF) magnetic field exposure on morphological and biophysical properties of human lymphoid cell line (Raji).
Raji cells exposed for 72 h to a 50 Hz, 2 mT (rms) sinusoidal magnetic field showed decreased membrane fluidity, reorganization of cytoskeletal components, and loss of microvilli on SEM with altered actin distribution. The authors also report evidence that ex…
Growth stage dependent effects of electromagnetic fields on DNA synthesis of Jurkat cells.
A 1.8 mT bone-healing electromagnetic field and 60 Hz power-frequency fields at 0.1 and 0.4 mT significantly inhibited DNA synthesis ([3H] thymidine uptake) in otherwise unstimulated Jurkat cells. Inhibition was most prominent in mid log phase cells, with ~50…
Delayed internal capsule infarctions following radiofrequency pallidotomy. Report of three cases.
Among 42 patients (50 pallidotomies), three patients experienced delayed postoperative strokes on Days 10, 51, and 117. The infarctions were ipsilateral to the pallidotomy site and appeared as high-intensity signals extending to the posterior limb of the inte…
Control of "choice" by application of the electromagnetic field equivalents of spoken words: mediation by emotional meaning rather than linguistic dimensions?
Electromagnetic equivalents (~1 microT) of spoken words applied across the temporoparietal lobes were associated with more frequent selection of the target word or words sharing its emotional dimensions in the exposed group (n=7) compared with a reference gro…
Influence of an alternating 3 Hz magnetic field with an induction of 0.1 millitesla on chosen parameters of the human occipital EEG.
In a randomized, blind, crossover, sham-controlled study of 62 volunteers, a vertically applied alternating 3 Hz magnetic field (0.1 mT) for 20 minutes produced statistically significant differences versus sham in occipital EEG relative spectral amplitudes in…
[The action of a modulated electromagnetic field on the emotional component of the systemic organization of behavioral acts in rats].
The paper reviews experimental findings on effects of a modulated electromagnetic field (MEMF) on rats' emotional responses during different phases of behavioral organization. It reports blocking effects of MEMF in simulated self-stimulation and in various co…

The effect of pulsed and sinusoidal magnetic fields on the morphology of developing chick embryos
Exposure to weak pulsed magnetic fields and 60 Hz sinusoidal magnetic fields approximately doubled to tripled the rate of morphological abnormalities in developing chick embryos. One campaign showed no significant effect, possibly due to genetic differences i…
Behavioral teratologic studies using microwave radiation: is there an increased risk from exposure to cellular phones and microwave ovens?
In rat prenatal exposure studies at nonhyperthermal power density levels, 915 MHz exposure showed no consistent significant alterations across assessed teratologic or behavioral parameters. 2450 MHz exposure was associated with significantly increased adult o…
[Evaluation of selected functional circulation parameters of workers from various occupational groups exposed to electromagnetic fields of high frequency. III. 24-h monitoring of arterial blood pressure (ABP)].
Mean arterial blood pressure and the day/night blood pressure variability indicator showed no significant differences between groups. Daily heart rate was significantly lower in middlewave broadcast station workers versus controls, and the day/night heart rat…

Childhood leukemia and electromagnetic fields: results of a population-based case-control study in Germany.
In this population-based case-control study, children exposed to >0.2 microT had an elevated but not statistically significant odds ratio for leukemia (OR 3.2, 95% CI 0.7–14.9), based on 4 cases and 3 controls in the high-exposure category. Exploratory analys…
Effect of 50-Hz electromagnetic field on the retention of toxic radionuclides in rat tissues.
In rats exposed to a 50 Hz, 10 mT EMF, pre-exposure or post-exposure produced small but significant changes in retention of ionic 210Po: pre-exposure decreased skin retention by 28% and total retention in investigated tissues by 10%, while post-exposure incre…
