The aim of the present work was to investigate the effects of the radiofrequency (RF) electromagnetic fields (EMFs) on human resting EEG with a control of some parameters that are known to affect alpha band, such as electrode impedance, salivary cortisol, and caffeine. Eyes-open and eyes-closed resting EEG data were recorded in 26 healthy young subjects under two conditions: sham exposure and r...

The purpose of this article was to present a brief review pertinent information regarding the effects microwave radiation on biological systems. Researchers have been intrigued by interaction electromagnetic fields (EMFs) and various life processes since 18th century. Microwaves refer oscillation an EMF with wavelength 1 mm m, which penetrates matter varying degrees. With widespread ever-increa...

The extensive use of mobile phone communication has raised public concerns about adverse health effects of radiofrequency (RF) electromagnetic fields (EMFs) in recent years. A central issue in this discussion is the question whether EMFs enhance the permeability of the blood-brain barrier (BBB). Here we report an investigation on the influence of a generic UMTS (Universal Mobile Telecommunicati...

Reduced reproductive success of birds nesting near power lines has been documented but never directly attributed to electromagnetic fields (EMFs). Laboratory studies have identified EMF effects on embryonic development, but reproductive success of wild birds is dependent on additional factors, including fertility, egg size, hatching, and fledging success. We tested whether EMFs affect reproduct...

The present study describes an investigation by fluorescence quenching, circular dichroism and UV-visible spectroscopy of the interaction between norfloxacin (NRF) and human serum albumin (HSA) in the presence of electromagnetic fields (EMFs). The results obtained from this study indicated that NRF had a strong ability to quench HSA at λ(ex) = 280 nm. In addition, a slight blue shift occurred, ...

We examined whether exposures to mobile phone radiation in biological/clinical experiments should be performed with real-life Electromagnetic Fields (EMFs) emitted by commercially available mobile phone handsets, instead of simulated EMFs emitted by generators or test phones. Real mobile phone emissions are constantly and unpredictably varying and thus are very different from simulated emission...

Insects are exposed to environmental radio frequency electromagnetic fields (RF-EMFs), which partially absorbed by their body. This absorption is currently unknown for most insect types. Therefore, numerical simulations were performed study the far-field of RF-EMFs different types at frequencies between 2 and 120 GHz, (expected be) used in (future) wireless communication. The done using anatomi...

Proposed offshore windfarm sites could overlap with the brooding and spawning habitats of commercially important crustacea, including European lobster, Homarus gammarus Edible crab, Cancer pagurus. Concerns have been raised on biological effects Electromagnetic Fields (EMFs) emitted from subsea power cables early life history these species. In this study, ovigerous female H. C. pagurus were exp...

AIM The aim of this article was to explore the hypothesis that non-thermal, weak, radiofrequency electromagnetic fields (RF-EMF) have an effect on living plants. SUBJECT AND METHODS In this study, we performed an analysis of the data extracted from the 45 peer-reviewed scientific publications (1996-2016) describing 169 experimental observations to detect the physiological and morphological ch...

Prof. Pilla (2013) presents a well-documented and highly integrated model of non-thermal therapeutic effects of pulsed/ modulated electromagnetic fields (EMFs). The model involves increased intracellular Ca, stimulation of calmodulin-dependent signaling both via Ca elevation and via direct EMF effects on calmodulin, Ca/calmodulin stimulation of cNOS activity/nitric oxide (NO) elevation/stimulat...
