The aim of this study was to test whether extremely low frequency electromagnetic fields (ELF EMFs) affect health or not. Here, we constructed a 100-μT/50 Hz electromagnetic field atmosphere. A total of 128 rats were randomly assigned into two groups: the ELF EMF group and the sham group. The ELF EMF group was exposed to 100-μT/50-Hz ELF EMF for 20 h per day for three months; at the same time t...

8 1.4.1 Introduction Spectroscopy, or the study of the interaction of light with matter. has become one of the major tools of the natural and physical ciences during this century. As the wavelength of the radiation is varied across the electromagnetic spectrum, characteristic properties of atoms, molecule , liquid and solids are probed. In the optical and ultraviolet regions (A. ""' I J-Lm up t...

Low-energy electromagnetic fields pulsed at frequencies of 10-90 Hz significantly increase healing of chronic fracture nonunions in man. These fields are effective at tissue current levels several orders of magnitude lower than those required for transmembrane depolarization of normal cells. We have examined the effects of two clinically used pulsed electromagnetic fields on cultures of the ost...

Studies have demonstrated that electromagnetic waves, as the one of the most important physical factors, may alter cognitive and non-cognitive behaviors, depending on the frequency and energy. Moreover, non-ionizing radiation of low energy waves e.g. very low frequency waves could alter this phenomenon via alterations in neurotransmitters and neurohormones. In this study, short, medium, and lon...

electromagnetic methods are widely used for the study of subsurface resistivity structures. these methods are based on the response of the subsurface structures to electromagnetic fields. the magnetotelluric (mt) method is an electromagnetic technique that uses the natural, time varying electric and magnetic field components measured at right angles to the surface of the earth, to make inferenc...

Carbachol, a muscarinic receptor agonist, produced three distinct spontaneous oscillations in the CA3 region of rat hippocampal slices. Carbachol concentrations in the 4-13 microM range produced regular synchronized CA3 discharges at 0.5-2 Hz (carbachol-delta). Higher concentrations (13-60 microM) produced short episodes of 5-10 Hz (carbachol-theta) oscillations separated by nonsynchronous acti...

background : electromagnetic fields are associated with production, transmission and use of electricity. in this  tudy we have investigated the effects of short and long time alternative magnetic fields' (amf, 50 hz) exposure on the secretion of hypothalamic-pituitary-gonadal axis in the male rats. methods : forty eight wistar male rats, same range of age and weight were divided into four group...

background: men are unavoidably exposed to ambient electromagnetic fields (emf) generated from various electrical gadgets and from power transmission lines. prostate gland plays an important role in secretion of semen as largest accessory gland of male reproductive system. it seems that protection of this gland against emf is important in spermatogenesis process. objective: the goal of this stu...
