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...
this paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. when a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near o...
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: the aim of the present study is to investigate the effect of interaperitoneal injection of baclofen (gaba-b agonist) and cgp35348 (gaba-b antagonist) on serum testosterone concentration in aggressive rats exposed to electromagnetic field. methods: fifty five mature male rats weighing 200±20 grams were studied. animals were divided into 2 main groups and four subgroups. main groups...
in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...
In this research, the effects of electromagnetic fields of various strengths (0, 1 and 2mT) have been investigated on antioxidant enzymes activity in Valerian (Valeriana officinalis L.). The dry and wet (soaked for 30 min) Valerian seeds were exposed to electromagnetic fields 30 min per day for 3 days. Each treatment and control groups had 3 replicates and 10 seeds were employed for each replic...
Introduction: The highest electromagnetic radiation pollution is related to the radiofrequency waves of mobile phones (1). Up to 70% of these waves can be absorbed by various tissues (2). Absorption of these waves can damage the body tissues by causing oxidative stress (3). Given that melatonin plays an antioxidant role, it seems that this hormone can have a protective effect on the hepato- tox...
background: exposure to extremely low frequency electromagnetic fields is increasingly common, but the potential influence on pregnant women has not been thoroughly investigated. methods: in this case-control study, 58 women who had an unexplained spontaneous abortion at < 14 weeks gestation and 58 matched pregnant women >14 weeks gestation were enrolled in 2012. the women completed the questio...
Background and purpose: Ëffect of electromagnetic filed on the living beings is one of the current issues. With development of technology and increasing application of electromagnetic waves in industry and health affairs, men is exposed to various electromagnetic fields, such as high pressure power cable, radio, ultra magnetic matters, television, mobile and computer. The purpose of this s...
mobile phones are two-way radios that emit electromagnetic radiation in microwave range. as the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. as self-monitoring of blood glucose can be a beneficial part of diabetes control, ho...
