The exposures to extremely low frequency magnetic field (ELF-MF) in our environment have dramatically increased. Epidemiological studies suggest that there is a possible association between ELF-MF exposure and increased risks of cardiovascular disease, cancers and neurodegenerative disorders. Animal studies show that ELF-MF exposure may interfere with the activity of brain cells, generate behav...
Previous studies have shown that the male reproductive system is one of the most sensitive organs to electromagnetic radiation. However, the biological effects and molecular mechanism are largely unclear. Our study was designed to elucidate the epigenetic effects of 50 Hz ELF-EMF in vitro. Mouse spermatocyte-derived GC-2 cell line was exposed to 50 Hz ELF-EMF (5 min on and 10 min off) at magnet...
In the relatively few years since empirical research into English as a Lingua Franca began being conducted more widely, the field has developed and expanded remarkably, and in myriad ways. In particular, researchers have explored ELF from the perspective of a range of linguistic levels and in an ever-increasing number of sociolinguistic contexts, as well as its synergies with the field of Inter...
Background/Aims Liver stiffness (LS) was assessed using transient elastography, and the enhanced liver fibrosis (ELF) test was performed to accurately assess fibrotic burden. We validated the LS-ELF algorithm and investigated whether the sequential LS-ELF algorithm performs better than concurrent combination of these analyses in chronic hepatitis B (CHB) patients. Methods Between 2009 and 201...
Lactoferrin (LF), a multifunctional glycoprotein in mammalian milk, is reported to exert a modulatory effect on lipid metabolism. The aim of the present study was to elucidate whether enteric-coated LF (eLF) might improve visceral fat-type obesity, an underlying cause of the metabolic syndrome. Using a double-blind, placebo-controlled design, Japanese men and women (n 26; aged 22-60 years) with...
Topographic maps, which maintain the spatial order of neurons in the order of their axonal connections, are found throughout the nervous system. In the visual retinotectal projection, ELF-1, a ligand in the tectum, and its receptors in the retina show complementary gradients in expression and binding, indicating they may be positional labels for map development. Here we show that ELF-1 acts as ...
ELF/VLF waves can be generated via amplitude modulated HF heating of the auroral electrojet, which turns a patch of ionospheric currents into a radiating antenna. A new, more powerful technique, termed `geometric modulation', involves scanning the HF beam in geometric patterns with no power modulation. Utilizing results obtained from the HAARP facility, we show that geometric modulation enhance...
Several members of the Ets (E26 transformation specific) transcription factor family are involved in tumor progression, e.g. by activating matrix metalloproteases. Ets proteins share a unique DNA-binding domain, the Ets domain, which specifically recognizes GGAA/T-containing sequences common in many promoters. While the roles of quite a number of Ets proteins in carcinogenesis have been well es...
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 ...
Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...
