During the last few years, our research group has been investigating the phenomenon of adaptive response in animals exposed to non-ionizing radiofrequency fields. The results from several separate studies indicated a significant increase in survival, decreases in genetic damage as well as oxidative damage and, alterations in several cellular processes in mice pre-exposed to radiofrequency field...

BACKGROUND Metastatic cancer is the most common malignant disease of the skeletal system. Traditionally, conventional fractionated external beam radiotherapy has been the treatment of choice. Recently, minimally invasive surgical techniques (MISS) have been added to the therapeutic armamentarium. The purpose of our study was to assess the effectiveness and safety of Radiofrequency Heat Ablation...

With an ever increasing number of cell phone users since late twentieth [corrected] century, magnitude of the problem of exposure to radiation emitted by cell phone is self evident. Extensive research had been devoted to incriminate or absolve it as a health hazard. Radiofrequency radiation emitted by cell phone had been stated to be a potent carcinogen, cytotoxic, genotoxic, mutagenic and neur...

BACKGROUND Catheter ablation with the use of radiofrequency current has been introduced as a therapeutic option for patients with tachyarrhythmias mediated by an accessory atrioventricular pathway. The technique conventionally implies the introduction of several catheters into the heart for assessment of electrophysiological parameters as well as for localization of the accessory pathway and ma...

Pain associated with cancer is often difficult to treat, even more so when tumors involve peripheral nerves. Therapy is complex and often requires a multimodal approach that can include medications, radiation, and interventional techniques. These components are utilized with variable success, but are also limited by known complications or adverse effects. We present the case of a 53-year-old wo...

The aim of this study was to determine whether the teratogenic effects of radiofrequency (RF) radiation are due to induced hyperthermia at 27.12 MHz. This was achieved by controlling the degree of temperature change and the duration of the elevation at this RF frequency. Pregnant Sprague-Dawley rats, at 9 days gestation were either sham-irradiated or irradiated with continuous shortwave radiati...

In the present study, the alteration in the sleep EEG in rats due to chronic exposure to low-level non-thermal electromagnetic radiation was investigated. Two types of radiation fields were used; 900 MHz unmodulated wave and 900 MHz modulated at 8 and 16 Hz waves. Animals has exposed to radiation fields for 1 month (1 h/day). EEG power spectral analyses of exposed and control animals during slo...
