مقدمه و هدف: استفاده از میدان های الکترومغناطیس در فرکانس های بسیار پایین در افزایش قند، تری گلیسیرید و اعتیاد به مورفین گزارش شده است. ازآنجایی که درد از مشکلات دائمی و داروهای مسکن موجود معمولاً مفید نیستند و مصرف آن ها عوارضی دارند، این پروژه با هدف ارزیابی (elf-mf) extremely low frequency magnetic field با استفاده از آزمون فرمالین انجام گردید. مواد و روش ها: مطالعۀ تجربی تصادفی در گروه های ...
With the effect of developing technology, humanity is constantly exposed to more electromagnetic fields. Regional studies are gaining importance for determining possible problems. In this study, extremely low-frequency field (ELF-EMF) measurements were carried out in Aydın Adnan Menderes University Central Campus areas where university students frequently found, at 25 randomly selected points, ...
Extremely low-frequency magnetic field (ELF-MF) has been suggested to influence the cognitive capability but this should be dynamically evaluated in a longitudinal study. Previous training can affect performance, but the influence under magnetic field is unclear. This study aims to evaluate the effects of previous training and ELF-MF exposure on learning and memory using the Morris water maze (...
The effect of extremely low frequency magnetic fields (50 Hz, 0.5 mT) - ELF-MF, on phosphate metabolism has been studied in the isolated ganglions of the garden snail Helix pomatia, after 7 and 16 days of snail exposure to ELF-MF. The influence of ELF-MF on the level of phosphate compounds and intracellular pH was monitored by ³¹P NMR spectroscopy. Furthermore, the activity of enzymes involved ...
We previously demonstrated that repeated exposure to extremely low frequency magnetic fields (ELF-MF) increases locomotor activity via stimulation of dopaminergic D1 receptor (J. Pharmacol. Sci., 2007;105:367-371). Since it has been demonstrated that activator protein-1 (AP-1) transcription factors, especially 35-kDa fos-related antigen (FRA), play a key role in the neuronal and behavioral adap...
We propose a mechanism to explain suggested links between seismic activity and ionospheric changes detected overhead. Specifically, we explain changes in the natural extremely low frequency (ELF) radio noise recently observed aboard the DEMETER satellite at night, before major earthquakes. Our mechanism utilises increased electrical conductivity of surface layer air before a major earthquake, w...
Introduction: Occupational exposure to Extremely Low Frequency Magnetic Fields (ELF-MFs) in train drivers is an integral part of the driving task and creates concern about driving jobs. The present study was designed to investigate the occupational exposure of Tehran train drivers to extremely low frequency magnetic fields. Methods: In order to measure the driver’s exposure, from each ...
Electrical devices currently used in clinical practice and common household equipments generate extremely low-frequency magnetic fields (ELF-MF) that were classified by the International Agency for Research on Cancer as "possible carcinogenic." Assuming that ELF-MF plays a role in the carcinogenic process without inducing direct genomic alterations, ELF-MF may be involved in the promotion or pr...
Extremely low-frequency electromagnetic fields (ELF-EMFs) can interact with biological systems. Although they are successfully used as therapeutic agents in physiatrics and rehabilitative practice, they might represent environmental pollutants and pose a risk to human health. Due to the lack of evidence of their mechanism of action, the effects of ELF-EMFs on differentiation processes in skelet...
The aims of this study were to evaluate the influence of an extremely low-frequency electromagnetic field (Elf-EMf) on [3H]glucose uptake in the peripheral tissues and organs of rats. rats were exposed to elF-emF (frequency-10 Hz, induction -1.8-3.8 mT) one hour daily for 14 consecutive days. control animals were sham exposed. on the 15th day (24 hours after last exposure) rats were injected wi...
