OBJECTIVES A widespread use of mobile phones evokes a growing concern for their possible adverse effects on the human central nervous system. This study was aimed at evaluating the effects of EMF generated by mobile phones, at all standard wavelengths: 450, 935 and 1800 MHz used in Poland, on the auditory brainstem-evoked responses (ABR) during and after the exposure. MATERIALS AND METHODS Th...

Objective Exposure to extremely low-frequency electromagnetic fields (ELF-EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO based on an increased risk for childhood leukemia. In case-control studies on brain tumors during 1997-2003 and 2007-2009 we assessed lifetime occupations in addition to exposure to different age...

Bio-effects mediated by non-ionizing electromagnetic fields (EMF) have become a hot topic of research in the last decades. This interest has been triggered by a growing public concern about the rapid expansion of telecommunication devices and possible consequences of their use on human health. Despite a feasibility study of potential negative impacts, the therapeutic advantages of EMF could be ...

What is Electrosensitivity? Electrosensitivity is a medically unexplained condition in which sufferers report experiencing adverse symptoms such as headaches, nausea or fatigue which are seemingly triggered by the presence of weak electromagnetic fields (EMF) such as those produced by mobile phones, computers or domestic appliances. The condition is controversial as there is no generally accept...

Introduction: Nitric Oxide is an important endogenous compound that acts as bronchodilator in trachea. Electromagnetic fields (EMF) affect nitric oxide level in different tissues. The interaction of nitrergic and cholinergic systems in airways has been reported. Therefore, the present study was performed to evaluate the interaction of cholinergic and nitrergic systems in the trachea of rats ...

This study overviews electromagnetic field (EMF) health impacts based on highly cited biomedical articles. It identifies health impacts resulting from exposure to EMF. A comprehensive query retrieved much of the relevant literature describing EMF health impacts, with strong emphasis on the mid and lower frequency nonionizing (radio/microwave and power frequencies) portion of the electromagnetic...

2 About the Scientific Committees Three independent non-food Scientific Committees provide the Commission with the scientific advice it needs when preparing policy and proposals relating to consumer safety, public health and the environment. The Committees also draw the Commission's attention to the new or emerging problems which may pose an actual or potential threat. SCENIHR Questions concern...

Plant sensitivity and its bio-effects on non-thermal weak radio-frequency electromagnetic fields (RF-EMF) identifying key parameters that affect plant sensitivity that can change/unchange by using big data analytics and machine learning concepts are quite significant. Despite its benefits, there is no single study that adequately covers machine learning concept in Bioelectromagnetics domain yet...
