Introduction: The present research aimed to examine Visual Working Memory (VWM) test scores, as well as hormonal, genomic, and brain anatomic changes in the male rhesus macaques exposed to Extremely Low Frequency Magnetic Field (ELF-MF). Methods: Four monkeys were exposed to two different ELF-MF frequencies: 1 Hz (control) and 12 Hz (experiment) with 0.7 µT (magnitude) 4 h/d for 30 conse...

Insomnia is one of the most common sleep disorders, characterized by difficulties in sleep initiation, sleep maintenance or early morning awakening. Sleepiness is also such issues that associated with driving accidents, work accidents, and reduces efficiency and numerous interpersonal difficulties. The aim of the present study is to evaluate the severity of insomnia and sleepiness workers who w...

The purpose of this study is to assess the impact low-frequency electromagnetic fields (LF-EMFs = 0.5 MHz) on phenotypic and genotypic levels concerning antibiotic resistance, antimicrobial-resistant (AMR) genes, resistance mechanisms Pseudomonas aeruginosa (P. aeruginosa). In study, bacterial isolates were exposed MHz then inoculated a new medium for assessment their sensitivity. results showe...

An extremely large earthquake (with magnitude of 8.2) happened on 8 August 1993 near the Guam island, and ultra-low-frequency (ULF) (frequency less than 1 Hz) electromagnetic fields were measured by 3-axis induction magnetometers at an observing station (with the epicentral distance of 65 km) with sampling frequency of 1 Hz. In order to study electromagnetic signature of prefracture criticality...

In the recent years, the task of estimating the currents induced within the human body by environmental electromagnetic fields has received increased attention from scientists around the world. While important progress was made in this direction, the unpredictable behaviour of living biological tissue made it difficult to quantify its reaction to electromagnetic fields and has kept the problem ...

Previous studies have shown that magnetic fields have subtle effects on pain perception in animals as well as humans. Experiments with sinusoidal extremely low frequency magnetic fields as well as pulsed electromagnetic fields (PEMF) have indicated that PEMF may have a larger analgesic effect, and so may be more clinically relevant. Indeed, these effects have been demonstrated to be specific to...

Background: Human beings are unavoidably exposed to ambient electromagnetic fields (EMF) generated from various electrical devices and from power transmission lines. The effects of extremely low-frequency electromagnetic fields (ELF-EMF) on the biological functions of living organisms represent an emerging area of interest for human health. One of the critical issues is that EMF may adversely a...

During the last decades studies addressing the effects of exposure to Extremely Low Frequency Electromagnetic Fields (ELF-EMF) have pointed out a possible link between those fields emitted by power lines and childhood leukaemia. They have also stressed the importance of also including in the assessment the contribution of frequency components, namely harmonics, other than the fundamental one. B...
