for many years it was believed that extremely lowfrequency electromagnetic field (elf-emf) do not have any significant biological effects. in this study, the influence of extremely low-frequency electromagnetic fields on the growth performance, serum antioxidant power and gastrointestinal structure of rainbow trout were evaluated. rainbow trout (17-18 g) were exposed to electromagnetic fields (...
introduction measuring magnetic induction phase shift (mips) changes as a function of cerebral hemorrhage volume has the potential for being a simple method for primary and non-contact detection of the occurrence and progress of cerebral hemorrhage. our previous mips study showed that the intracranial pressure (icp) was used as a contrast index and found the primary correlation between mips and...
The objective of this paper is to survey the results of studies on the biological effects of electromagnetic fields on fish. First, the basic concepts of electromagnetism and electromagnetic spectrum and the importance of studying it in the case of fish are discussed. Then a summary of the results obtained on the effects of extremely low frequency electromagnetic fields (ELF-EMFs) and radiofreq...
The term "electromagnetic fields" (EMF) is a combination of electric and magnetic fields as a diagnostic method as well as a therapeutic tool with many advantages such as ease of operation and painlessness, very controllable, which today has found wide application in regenerative medicine and also cancer treatment. In addition to organs such as nerves, hearts, and bones that have an electrica...
objective(s):electromagnetic radiations which have lethal effects on the living cells are currently also considered as a disinfective physical agent. materials and methods: in this investigation, silver nanoparticles were applied to enhance the lethal action of low powers (100 and 180 w) of 2450 mhz electromagnetic radiation especially against escherichia coli atcc 8739. silver nanoparticles ...
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...
BACKGROUND Electrical stimulation is used to treat nonunions and to augment spinal fusions. We studied the biochemical pathways that are activated in signal transduction when various types of electrical stimulation are applied to bone cells. METHODS Cultured MC3T3-E1 bone cells were exposed to capacitive coupling, inductive coupling, or combined electromagnetic fields at appropriate field str...
Introduction: In recent years, use of compact fluorescent lamps has increased in order to optimize energy consumption. The aim of this study was to evaluate the radiations of electromagnetic spectrum from usual compact fluorescent lamps. Methods: In this study, 48 compact fluorescent lamps from different brands and cover (warm – cool) were selected. For studied lamps, operational facto...
Introduction: Today the rate of human beings exposed to electromagnetic fields is increasing deliriously and human beings are being more drowned in the ocean of electromagnetic fields each day. It has been a long time that the effects of electromagnetic fields on organisms has been studied by researchers and due to the long-term researches and the slow impact of fields on life-cycle processes, ...
