Pulsed radiofrequency (PRF) fields applied by an electrode to neural structures, such as the peripheral sensory nociceptor axons and dorsal root ganglion, are clinically effective in reducing pain and other neuropathic syndromes. However, a full understanding of the underlying mechanisms by which this occurs has not yet been clarified. In this study, PRF is applied to the afferent axons of the ...
background: over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. this study aimed to assess whether radiofrequency radiation can induce adaptive r...
The signs of radiofrequency phases and frequencies used in are also fraught with subtle sign problems, for example, NMR are examined carefully. Some fundamental problems with cross-correlated relaxation (4–9) , nuclear demagnetizing current usage are exposed by simple examples. The entire chain of field effects (10–13) , and phase or frequency shifts induced events leading to the NMR spectrum i...
Along with the explosive growth of products and services utilized in modern information technology applications, wireless communication systems have become essential part of working life. Though majority of workers are exposed to radiofrequency (RF) fields from wireless systems, most telecommunication devices produce field strengths that can be considered harmless. However, there are certain wo...
This paper reviews the literature data on the genetic toxicology of radiofrequency (RF) radiation. Whereas in the past most studies were devoted to microwave ovens and radar equipment, it is now mobile telecommunication that attracts most attention. Therefore we focus on mobile telephone frequencies where possible. According to a great majority of the papers, radiofrequency fields, and mobile t...
Introduction: Electrochemotherapy (ECT) is a cancer treatment modality to permeabilize cell membrane facilitating the non-permeant molecules to gain access to the cytosol of cells. Nevertheless, environmental electromagnetic fields (EMFs) may disturb the efficiency of ECT. The present study aimed to investigate the effect of EMFs 900 MHz pulse-modulated by 217 Hz extremely low-frequency fields ...
