High-voltage electricity lines are known to generate extremely low-frequency electromagnetic fields (ELF-EMFs). With the process of urbanization, increasing concerns has been focused on the potentially hazardous impacts of ELF-EMF on human health, and the conclusions are controversial. Little is known about the method of prevention against ELF-EMF induced healthy problems. A total of 186 male w...

The reports dealing with the effects of electromagnetic fields (EMFs) on brain electrical activity have been inconsistent. We suspected that the use of linear methods and models accounted for some of the variability, and we explored the issue by using a novel approach to study the effects of EMFs on the electroencephalogram (EEG) from rabbits. The EEG was embedded in phase space and local recur...

OBJECTIVES The aim of this study was to determine if grounding in the presence of electromagnetic fields (EMFs) encountered in a normal housing environment produces harmful currents in the human body. DESIGN This study had a test-retest design, with duration of 5-15 min per participant. PARTICIPANTS There were 50 participants, of whom 23 were males aged 12-77 years (Mage ± standard deviatio...

Electromagnetic fields (EMFs) are present throughout the modern world and are derived from many man-made sources including overhead transmission lines. The risks of extremely-low frequency (ELF) electromagnetic fields are particularly poorly understood especially at high field strengths as they are rarely encountered at ground level. Flying insects, however, can approach close to high field str...

The potential effect of electromagnetic fields (EMFs) emitted from video display terminals (VDTs) to elicit biological response is a major concern for the public. The software professionals are subjected to cumulative EMFs in their occupational environments. This study was undertaken to evaluate DNA damage and incidences of micronuclei in such professionals. To the best of our knowledge, the pr...

OBJECTIVE To comprehensively analyze the relationship between exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and the development of female breast cancer. METHODS Reports of case-control studies published from 1990 to 2010 were analyzed. The quality effect model was chosen to calculate total odds ratio (OR) depending on the data in studies and quality scores. Subgroup an...

For many years electromagnetic fields (EMFs) have been used clinically with various settings as an exogenous stimulation method to promote fracture healing. However, underlying mechanisms of action and EMF parameters responsible for certain effects remain unclear. Our aim was to investigate the influence of defined EMFs on human osteoblasts' and osteoclasts' viability and function. Primary huma...

The fact that electromagnetic fields (EMFs) have biological effects has been investigated not only for the health risks they invoke, but the potential for healing that has also been suggested. Much of the research originally was undertaken in those countries that had been unwilling or unable to afford the sort of expensive high-tech medical equipment used in many medical interventions in the We...

Abstract Background The general population is exposed to Radio-Frequency Electromagnetic Fields (RF-EMFs) used by telecommunication networks. Previous studies developed methods assess this exposure. These will be inadequate accurately exposure in 5G technologies or other wireless using adaptive antennas. This due the fact that NR (new radio) base stations focus actively on connected users, resu...
