The aim of this study was to investigate the effect of continuous extremely low frequency magnetic fields (ELF-MFs) with a frequency of 10 Hz and an intensity of 690-720 μT on the level of 5-hydroxyindolacetic acid (5-HIAA) in adult male Wistar rats. A total of 24 adult Wistar male rats were used, and after exposure with an ELF-MF for 15 successive days, all rats in each test were anesthetized ...

Animal studies have shown that electromagnetic field exposure may interfere with the activity of brain cells, thereby generating behavioral and cognitive disturbances. However, the underlying mechanisms and possible preventions are still unknown. In this study, we used a mouse model to examine the effects of exposure to extremely low-frequency (50 Hz) electromagnetic fields (ELF MFs) on a recog...

This study was performed to investigate the effects of extremely low frequency pulsed electromagnetic fields (ELF-PEMFs) on the proliferation and differentiation of human alveolar bone-derived mesenchymal stem cells (hABMSCs). Osteogenesis is a complex series of events involving the differentiation of mesenchymal stem cells to generate new bone. In this study, we examined not merely the effect ...

The present study was designed to investigate the influence of Extremely low frequency magnetic field (ELF MF) on depression related behavior, and mechanism involved therein. Mice were exposed to ELF MF (50Hz, 10G) 8h/day for 7, 30, 60, 90 and 120 days. Depression was assessed using forced swim test (FST), in which no significant effect was observed on 7 t h, 30t h, 60 t h, 90t h exposure day. ...

This paper demonstrates a method of extracting programs from formal deductions represented in the Edinburgh Logical Framework, using the Elf programming language. Deductive systems are given for the extraction of simple types from formulas of rst-order arithmetic and of-calculus terms from natural deduction proofs. These systems are easily encoded in Elf, yielding an implementation of extractio...

Observations of extremely low frequency (ELF) radio atmospherics (sferics), the transient electromagnetic fields radiated by lightning discharges, are used to determine the current moment waveforms of vertical lightning discharges. In order to extract this information the propagation of radio atmospherics from source to receiver must be modeled accurately, especially in view of the important ro...

Epidemiologic studies have shown the relation between exposure to extremely low frequency magnetic fields (ELF-MFs) and childhood leukemia, so assessment of children exposure levels in different environments is considered as a serious precedence. Present study aimed at determining ELF-MFs flux densities near schools in Tehran. Measurements were performed near randomly selected schools in three ...

Total body weight of newborns, the volume of spleen, and the number of megakaryocytes decreased following the exposure to ELF-MF (6 x 10(-3) T and 50 Hz) at 1-5, 6-10, 11-15, and 16-20 days of pregnancy of mice. The complete period of gestation was sensitive to ELF-MF exposure; the initial days were more prone to exposure. The results suggest that the use of ELF-MF producing instruments should ...

The respiratory manifestations of cystic fibrosis (CF) are characterized by neutrophil-dominated airway inflammation. Since a variety of inflammatory stimuli are capable of inducing bronchial epithelial cells to express the gene for IL-8, a cytokine that attracts and activates neutrophils, mediators in respiratory epithelial lining fluid (ELF) of CF individuals might induce IL-8 production by e...

The prognosis in gastric cancer has been almost unchanged for the last 20 years. At the time of diagnosis the majority of patients have disseminated disease. The 5-year survival is only about 15%. Several efforts with numerous antineoplastic regimens have been studied. The most widely used regimen has been the FAM (5-fluorouracil, adriamycin, mitomycin C) regimen. Because of the cardiotoxicity ...
