Modern civilization is an electromagnetic one. Low frequency electromagnetic fields (EMFs) showed to exert quite subtle biologic effects as a consequence of continuous exposure of living beings to their influence and the summing up of their otherwise limited impact. If high frequency and microwave EMFs are now considered potentially dangerous due to some controversial experimental results and c...

The objective of this paper is to survey the results of studies on the biological effects of electromagnetic fields on fish. First, the basic concepts of electromagnetism and electromagnetic spectrum and the importance of studying it in the case of fish are discussed. Then a summary of the results obtained on the effects of extremely low frequency electromagnetic fields (ELF-EMFs) and radiofreq...

mri workers are occupationally exposed to static and time-varying gradient magnetic fields.  while the 24-hour time-averaged exposure to static magnetic fields is about a few mt, the maximum static field strength can be as high as 500 mt during patient set up. over the past several years, our lab has performed extensive experiments on the health effects of exposure of animal models and humans t...

Life on Earth is constantly exposed to natural electromagnetic fields (EMFs), and it is generally accepted that EMFs may exert a variety of effects on biological systems. Particularly, extremely low-frequency electromagnetic fields (EL-EMFs) affect biological processes such as cell development and differentiation; however, the fundamental mechanisms by which EMFs influence these processes remai...

Following an increase in the use of electric appliances that can generate 50 or 60 Hz electromagnetic fields, concerns have intensified regarding the biological effects of extremely low-frequency electromagnetic fields (ELF-EMFs) on human health. Previous epidemiological studies have suggested the carcinogenic potential of environmental exposure to ELF-EMFs, specifically at 50 or 60 Hz. However...

Introduction: In recent years the relationship between electromagnetic fields and coronary artery disease is attracted a considerable attention. Low density lipoprotein (LDL) oxidation is the initial step in the development of atherosclerosis. Paraoxonase1 (PON1) protects LDL and High density lipoprotein (HDL) against oxidative processes, thus preventing the formation of atherogenic (oxidized-L...

a large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (rf-emfs) such as common mobile phones and magnetic resonance imaging (mri). studies performed on the increased microleakage of dental amalgam restorations after exposure to rf-emfs have further supported th...
