mri workers are occupationally exposed to static and time-varying gradient magnetic fields.  while the 24-hour time-averaged exposure to static magnetic fields is about a few mt, the maximum static field strength can be as high as 500 mt during patient set up. over the past several years, our lab has performed extensive experiments on the health effects of exposure of animal models and humans t...

Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF) have beenwell demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. After an osteotomy of the midshaft radius...

Ammonium removal is a key step in biological wastewater treatment and novel approaches that improve this process are in great demand. The aim of this study is to test the hypothesis that ammonium removal from wastewater can be stimulated by static magnetic fields. This was achieved by analysis of the effects of static magnetic field (SMF) on the growth and activity of Nitrosomonas europaea, a k...

recently, the hypothesis in which memory and information would be stored as magnetic forms in astrocytes is expanding and neuromagnetic interactions between neurons and neighboring astrocytes in neocortex have potential to be the basis of memory formation. it has been proposed that all sorts of information may be maintained in form of neuronal activity-associated magnetic fields (naamfs) and th...

This study presents experimental data for the effects of weak radio frequency (RF) magnetic fields on hydrogen peroxide (H2O2) production and cellular growth rates of fibrosarcoma HT1080 cells in vitro. Cells were exposed either to 45 µT static magnetic fields (SMFs)-oriented vertical to the plane of growth or to SMFs combined with weak 5 and 10 MHz RF magnetic fields of 10 µTRMS intensity perp...

The available evidence from in vitro and in vivo studies is deemed not sufficient to draw conclusions about the potential health effects of static magnetic field (SMF) exposure. Therefore, the aim of the present study was to determine the influence of static magnetic fields and phloretin on the redox homeostasis of human dermal fibroblasts. Control fibroblasts and fibroblasts treated with phlor...

Cellular stress response proteins like Hsp70 may be affected by exposure to static magnetic fields (SMF). We examined whether exposure to a 100 mT SMF and GSH-depleting diethymaleate (DEM) would affect the levels of Hsp70 mRNA in HL-60 cells. Cells were exposed to SMF, DEM, a combination of DEM and SMF as well as 42oC. We found that only exposure to 42oC significantly affected the levels of Hsp...

The results of studies on the biological influence of magnetic fields are controversial and do not provide clear answers regarding their impact on cell functioning. Fluoride compounds are substances that influence free radical processes, which occur when the reactive forms of oxygen are present. It is not known whether static magnetic fields (SMF) cause any changes in fluoride assimilation or a...

Background: Expansion of the use of magnetic fields in metals, mining, transport, research, and medicine industries has led to a discussion about the effects of magnetic fields and whether their strength is negligible. The aim of this study was to investigate the effects of magnetic field on the viability and proliferation rate of HeLa cells. Materials and methods: We studied the effects of ma...
