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…
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…
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 of Akata cells latently infected with EBV to a 50 Hz electromagnetic field increased the number of cells expressing EBV early antigens.
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…
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…
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…
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…
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…
Among 28 patients undergoing radiofrequency ablation of para-Hisian accessory pathways, 6 (21.4%) developed inappropriate sinus tachycardia 45–240 minutes after the procedure. IST resolved spontaneously within 72 hours in 5 patients; 1 required beta-blockers …
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…
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 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…

Necropsy 25 days after radiofrequency ablation of the AV junction showed subendocardial necrosis with signs of advanced organization and necrosis of adjacent fat tissue. A thrombotic occlusion of a small coronary artery branch in the right atrial posterior wa…

In 38 patients undergoing 44 radiofrequency catheter ablation procedures, heart rate increased transiently after ablation and all time- and frequency-domain heart rate variability parameters showed significant reversible decreases. These changes were reported…
After radiofrequency modification of the AV junction reduced mean ventricular rate from 120 bpm to 60 bpm, the patient developed nonsustained or sustained polymorphic ventricular tachycardias starting 5 hours post-procedure and during the following week, desp…
In 20/38 cases (53%), unusual pacemaker responses occurred during RF energy application, including inhibition, backup mode, noise mode, temporary RF-induced pacemaker tachycardia, oversensing, and transient loss of capture. Most devices returned to full funct…
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…
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…
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…
