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...

introduction: the present study investigated the interactive effect of gabab receptors and extremely low frequency electromagnetic field (elf-emf) on foot shock-induced aggression in rats. methods: fifty adult male rats were randomly assigned into 10 groups. groups 2, 4, 6, 8 and 10 were exposed to 50 hz, 500 µt elf-emf for 30 days 8h per day while the remaining groups (1, 3, 5, 7 and 9) were s...

the efficacious effects of pulsed electromagnetic field (pemf) under the certain field parameters like frequency and the field intensity have been reported for various tissue and molecules. since collagen is found abundantly in most tissue structures, this research was designed to further investigate the effects of extremely low frequency (elf) pemf on the synthesis of the epidermal collagen. t...

extremely low frequency (elf) electromagnetic field (elf-emfs) are widely employed in electrical appliances and different equipment such as television sets, elf-emfs can  affect biological systems by increasing production  ros. the altered balance between ros generation and elimination plays a critical role in a variety of pathologic conditions. ros levels have been observed in several hematopo...

conclusions no interactivity is present in modulatory effects of gabaa receptors and elf-emfs on serum testosterone of male rats. patients and methods fifty adult male rats were randomly assigned into 10 groups. groups 2, 4, 6, 8, and 10 were exposed to elf-emf for 30 days 8hrs per day; while, the remaining groups (1, 3, 5, 7, and 9) were sham exposed animals. at the end of the experiment, anim...

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 (...

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...
