Although the modulation of Ca(2+) channel activity by extremely low-frequency electromagnetic fields (ELF-EMF) has been studied previously, few reports have addressed the effects of such fields on the activity of voltage-activated Na(+) channels (Na(v)). Here, we investigated the effects of ELF-EMF on Na(v) activity in rat cerebellar granule cells (GCs). Our results reveal that exposing cerebel...

background: rapidly increasing possibilities of exposure to environmental extremely low-frequency electromagnetic fields (elf-emf) have become a topic of worldwide investigation. epidemiological and laboratory studies suggest that exposure to elf-emf may increase cancer risk therefore assessment of chromosomal damage in various cell lines might be of predictive value for future risk estimation....

background: recently, there are increasing concerns and interests about the potential effects of electromagnetic field (emf) on both human and animal health. objective: the goal of this study was to evaluate the harmful effects of 50 hz non-ionizing emf on rat oocytes. materials and methods: in this experimental study 30 rats were randomly taken from laboratory animals and their ags and weights...

Background: It is proved that testis is sensitive to electromagnetic field (EMF) and its damage results in infertility. Exposure to EMF induces reactive oxygen species production and affects on anti-oxidants defense mechanisms. Metallothionein (MT) is a name for a group of low molecular weight (6-7 kDa), sulfhydryl rich proteins. Expression of MT1 and MT2 genes in testis tissue after EMF exposu...

Background: The aim of this study was to investigate the effect of the electromagnetic field (EMF) generated by 10 kV (50 Hz) high voltage line on the epididymal sperm characteristics and the protective effects of ganoderma lucidum (GL) and melatonin (M) in EMF exposed male rats. Materials and Methods: In this study, 64 Wistar rats were divided into 8 groups (n= 8). Rats in 26-day and 52-day ex...

This breakout group evaluated the data addressing EMF effects on cytosolic free calcium and other ions as well as the effect of EMF on calcium signaling pathways. A literature search of papers published from 1990 to 1996 showed approximately 25 manuscripts directly related to the topic (see Table 1 and References; note these searches are inevitably incomplete). The breakout group discussed seve...

The nonequilibrium properties of a driven quasi-one-dimensional superconducting ring subjected to a constant electromotive force (emf) is studied. The emf accelerates the superconducting electrons until the critical current is reached and a dissipative phase slip occurs that lowers the current. The phase-slip phenomena is examined as a function of the strength of the emf, thermal noise, and nor...

The potential health risks of exposure to high frequency electromagnetic fields (HF-EMF) associated with mobile telephony have become a great public concern. One area of particular interest relates to the ability of HF-EMF to induce a cellular stress response, which could conceivably cause alterations in cell physiology. Our research group evaluated different biological endpoints in cells expos...
