background: the effects of extremely low frequency electromagnetic fields (elf-emf) on toxoplasma gondii have not been explained yet. the aim of this study was to assess the possible effects of elf-emf on growth, survival time and viability of toxoplasma gondii . in addition, the life span of toxoplasma infected animals was investigated. methods: sixty adult male balb/c mice were used for in vi...

Background: This study aims to evaluate the negative health impacts of exposure to electromagnetic field and to prepare a risk map of two selected call centers. Materials and Methods: Two call centers whose electromagnetic field values were measured by calibrated low high and point frequency measurement device. The measurements were performed by following the EN 50492 Standards. 178 employees ...

Theoretical and experimental evidences support the hypothesis that extremely low-frequency electromagnetic fields can affect voltage-gated channels. Little is known, however, about their effect on potassium channels. Kv1.3, a member of the voltage-gated potassium channels family originally discovered in the brain, is a key player in important biological processes including antigen-dependent act...
