Microwave exposure enhanced aggregation of bovine serum albumin in vitro in a time- and temperature-dependent manner and promoted amyloid fibril formation by bovine insulin at 60 C. The reported conformational alterations were not accompanied by measurable te…
Rabbit eyes exposed to microwave power densities of 5 mW/cm^2 and 10 mW/cm^2 for 3 hours showed significant changes versus self-controls: at 5 mW/cm^2 early apoptosis was significantly increased, while at 10 mW/cm^2 secondary necrotic cells were significantly…

Rats exposed to 50 Hz (50–500 microT) ELF-EMF for 3 months showed decreased volume density of follicular epithelium and thyroid activation index and increased volume density of colloid and capillary network in groups assessed immediately and at 1–2 weeks post…
Exposure to intermittent 50 Hz ELF-EMF (20–1,000 µT; 1–24 h; 5 min on/10 min off) induced dose-dependent and time-dependent DNA single-strand and double-strand breaks in cultured human diploid fibroblasts. Effects were reported at magnetic flux density as low…
Cultured fibroblasts exposed to intermittent 50 Hz (1 mT) ELF-EMF for 1–24 h showed basal DNA strand break levels that correlated with donor age. A maximum response occurred at 15–19 h and was more pronounced in cells from older donors.
Using a 16-channel telemetric EEG system during mobile phone EMF exposure, the spectrum median frequency increased in areas close to the antenna after ~10–15 s, and slow-wave activity appeared after ~20–40 s in contralateral frontal and temporal areas, repeat…
In a cohort follow-up (1961–2002) with 99 breast cancer cases, breast cancer incidence was elevated versus the total Norwegian female population (SIR 1.30, 95% CI 1.05–1.58). In a nested case-control analysis, the highest cumulative exposure group had ORs of …
This retrospective analysis summarizes USSR experimental research on radiofrequency EMF and considers chronic laboratory animal exposures. It reports that RF EMF in the 1750–2750 MHz range at power density up to 100–500 W/cm2 was associated with changes in im…

After 1-hour exposure to ultra-short impulse low-frequency (6 Hz) superbroad band electromagnetic radiation, cortical EEG in rats was altered immediately after exposure. Paradoxical sleep in rabbits increased within 16–22 hours following radiation.

A case is described in which, after lung radiofrequency ablation, retracting the electrode hooks into the shaft was difficult and resulted in a split needle. The authors suggest charring of ablated tissue may cause tissue to catch between the hooks and shaft …
Mice exposed to 50 Hz sinusoidal magnetic fields (0.2 mT or 6.0 mT) for 2 or 4 weeks had higher c-fos mRNA levels in brain and liver compared with controls (reported as statistically significant, P<0.05). After 4 weeks, liver tissue showed higher expression w…
