INTRODUCTION To date, occupational exposure assessment of electromagnetic fields (EMF) has relied on occupation-based measurements and exposure estimates. However, misclassification due to between-worker variability remains an unsolved challenge. A source-based approach, supported by detailed subject data on determinants of exposure, may allow for a more individualized exposure assessment. Deta...

The expansion of mobile phone technology has raised concerns regarding the effect of 900-MHz electromagnetic field (EMF) exposure on the central nervous system. At present, the developing human brain is regularly exposed to mobile telephones, pre- and postnatally. Several studies have demonstrated the acute effects of EMF exposure during pre- or postnatal periods; however, the chronic effects o...

The direct targets of extremely low and microwave frequency range electromagnetic fields (EMFs) in producing non-thermal effects have not been clearly established. However, studies in the literature, reviewed here, provide substantial support for such direct targets. Twenty-three studies have shown that voltage-gated calcium channels (VGCCs) produce these and other EMF effects, such that the L-...

background: considerable attention is focused on effects of electromagnetic field (emf) and its increasing use in everyday life. appliances and various equipments are sources of electromagnetic fields with a wide-range of technical characteristics. objective: in this study we investigated the effect of emf (50 hz, 0.5 mt) on epididymis and deferens duct in mice. materials and methods: 30 balb/c...

BACKGROUND Sleep-dependent performance improvements seem to be closely related to sleep spindles (12-15 Hz) and sleep slow-wave activity (SWA, 0.75-4.5 Hz). Pulse-modulated radiofrequency electromagnetic fields (RF EMF, carrier frequency 900 MHz) are capable to modulate these electroencephalographic (EEG) characteristics of sleep. OBJECTIVE The aim of our study was to explore possible mechani...

BACKGROUND The effects of electromagnetic fields (EMFs) on cardiovascular calcification is unknown. We sought to evaluate the effects of EMF on vascular calcification in normal rats and in rats with chronic kidney disease (CKD) - a condition which promotes calcification. METHODS We used four groups of rats: group 1 - exposed to EMF, group 2 - not exposed to EMF, group 3 - rats with CKD expose...

The increased use of mobile phones has generated public concern about the impact of radiofrequency electromagnetic fields (RF-EMF) on health. In the present study, we investigated whether RF-EMFs induce molecular changes in amyloid precursor protein (APP) processing and amyloid beta (Aβ)-related memory impairment in the 5xFAD mouse, which is a widely used amyloid animal model. The 5xFAD mice at...

California coast live oak (Quercus agrifolia) forms tripartite symbiotic associations with arbuscular (AMF) and ectomycorrhizal (EMF) fungi. We selected oak individuals differing in topographic position and depth to groundwater (mesic valley vs. xeric hill sites) to investigate changes of tree mycorrhizal status in response to interannual rainfall variability. EMF root colonization, as well as ...

Endomyocardial fibrosis (EMF) is a neglected restrictive cardiomyopathy of unknown aetiology and unclear natural history, which causes premature deaths in endemic areas. We present the case of a 13-year-old boy from a highly endemic area, presenting with concurrent signs of chronic EMF and severe hypereosinophilia associated with active schistosomal cystitis. We discuss the possible role of thi...

background: it is proved that testis is sensitive to electromagnetic field (emf) and its damage results in infertility. exposure to emf induces reactive oxygen species production and affects on anti-oxidants defense mechanisms. metallothionein (mt) is a name for a group of low molecular weight (6-7 kda), sulfhydryl rich proteins. expression of mt1 and mt2 genes in testis tissue after emf exposu...
