PURPOSE The aim of the study was to determine how free radicals generation in blood platelets exposed to electromagnetic field (EMF) occurring in cars affects the process of these morphotic elements cell membranes phospholipid peroxidation. MATERIAL AND METHODS The suspension of human blood platelets was exposed to EMF of proper characteristics in a specially arranged research stand. After 30...

Few studies have investigated physiologic and cognitive effects of "long-term" electromagnetic field (EMF) exposure in humans or animals. Our recent studies have provided initial insight into the long-term impact of adulthood EMF exposure (GSM, pulsed/modulated, 918 MHz, 0.25-1.05 W/kg) by showing 6+ months of daily EMF treatment protects against or reverses cognitive impairment in Alzheimer's ...

Epidemiological studies have implicated maternal protein-calorie deficiency as an important public health problem in developing countries. Over the last decades, a remarkable diffusion of electricity and an increased level of the electromagnetic field (EMF) in the environment have characterized modern societies. Therefore, researchers are concerned with the biological effects of 50-60 Hz, EMF. ...

BACKGROUND The extremely low-frequency electromagnetic field (ELF-EMF), mainly emitted by electric transmission lines and household electronic appliances, is becoming a worldwide health risk. It is imperative to investigate the biological impacts of ELF-EMF and to identify products that are resistant to the radiation from 50 Hz ELF-EMF. In this study, we investigated the biological impacts of a...

BACKGROUND Studies investigating the effect of power frequency (50-60 Hz) electromagnetic fields (EMF) on melatonin synthesis in rats have been inconsistent with several showing suppression of melatonin synthesis, others showing no effect and a few actually demonstrating small increases. Scant research has focused on the ensuing sleep patterns of EMF exposed rats. The present study was designed...

Several publications in the scientific literature have raised concern about the individual and public health impact of adverse non-ionizing radiation (a-NIR) from electromagnetic field (EMF) exposure emanating from certain power, electrical and wireless devices commonly found in the home, workplace, school and community. Despite the many challenges in establishing irrefutable scientific proof o...

Three years after the first interlaboratory comparison programme (ILC) for extremely low frequency electromagnetic fields (ELF EMF), twelve participating laboratories measured the values of electric and magnetic fields including frequency in three stages at specified positions and distances from the field sources. This paper presents the measurements procedure, the results and their evaluation ...

mobile phones are two-way radios that emit electromagnetic radiation in microwave range. as the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. as self-monitoring of blood glucose can be a beneficial part of diabetes control, ho...

According to Directive 2013/35/EU, any assessment of hazards associated with exposure to electromagnetic fields (EMF) in the workplace needs an evaluation of quantities characterizing biophysical effects caused inside human bodies by exposure. Such quantities (induced electric field or specific energy absorption rate) may be evaluated by computer simulations in virtual models (phantoms), repres...

The blue-light sensitive photoreceptor cryptochrome (CRY) may act as a magneto-receptor through formation of radical pairs involving a triad of tryptophans. Previous genetic analyses of behavioral responses of Drosophila to electromagnetic fields using conditioning, circadian and geotaxis assays have lent some support to the radical pair model (RPM). Here, we describe a new method that generate...
