Introduction Over the last decades, considerable levels of electromagnetic fields (EMFs) have been characterized in the living environment. Recent epidemiological studies on occupational and residential exposure to EMF have shown that 50/60 Hz fields, known as extremely low frequencies (ELF), have various biological effects, such as angiogenesis. This study aimed to investigate the effect of en...

Extremely low-frequency electromagnetic fields (ELF-EMFs) can affect male reproductive function, but the underlying mechanism of this effect remains unknown. miRNA-mediated regulation has been implicated as an important epigenetic mechanism for regulatory pathways. Herein, we profiled miRNA expression in response to ELF-EMFs in vitro. Mouse spermatocyte-derived GC-2 cells were intermittently ex...

Unlike now widely used traditional methods of treatment of tumors by means of ionizing radiation and the chemotherapy, the method of the use of low intensity electromagnetic fields (EMF) is non-ionizing and noninvasive and hence is completely deprived of any harmful side effects. The present study was undertaken to investigate whether low-intensity EMFs can suppress tumoral cells growth in vivo...

Background: The rapidly increasing use of mobile phones has led to public concerns about possible health effects of these popular communication devices. This study is an attempt to investigate the effects of radiofrequency (RF) radiation produced by GSM mobile phones on the insulin release in rats.Methods: Forty two female adult Sprague Dawley rats were randomly divided into 4 groups. Group1 we...

The expanding marine renewable energy industry will increase the prevalence of electromagnetic fields (EMFs) from power cables in coastal waters. Assessments environmental impacts are required within licensing/permitting processes and increased questions concerning EMF emissions potential cumulative impacts. It is presumed that protecting a cable by burial, may also mitigate on species. Focussi...

Theoretically, the concepts of energy, entropy, exergy and embodied energy are founded in the fields of thermodynamics and physics. Yet, over decades these concepts have been applied in numerous fields of science and engineering, playing a key role in the analysis of processes, systems and devices in which energy transfers and energy transformations occur. The research reported here aims to dem...

Amniotic fluid (AF) is essential for fetal development and maturation during pregnancy. The levels of proteins in AF have been determined in many studies to screen for potential biomarkers of pregnancy-associated abnormalities. Alpha-fetoprotein (AFP) is a major AF and plasma protein produced by the yolk sac and the liver during the fetal period. APF serum concentrations are commonly used for s...

During recent years there has been increasing public concern on potential health risks from power-frequency fields (extremely low frequency electromagnetic fields; ELF) and from radiofrequency/microwave radiation emissions (RF) from wireless communications. Non-thermal (low-intensity) biological effects have not been considered for regulation of microwave exposure, although numerous scientific ...

Recent neurophysiological studies indicate that exposure to electromagnetic fields (EMFs) generated by mobile phone radiation can exert effects on brain activity. One technical solution to reduce effects of EMFs in mobile phone use is provided in mobile phone chips that are applied to mobile phones or attached to their surfaces. To date, there are no systematical studies on the effects of mobil...
