Background: Many studies have showed that electromagnetic field decrease anxiety. In this study the objectives: effect of Electromagnet Fields in Low Frequency in Induced Anxiety by formalin. Methods: 32 male mice with weight (30 grams) were classified in 4 groups (n=8), and received Histamine (5mg/kg IP injection) 3classes of every group exposed to electromagnetic field (emfs) with25, 50, 75 H...

Background: Our previous reports have used a novel method for imaging bioelectromagnetic energy as electromagnetic fields (EMFs) emanating from plant and animal tissue The purpose of this study is to demonstrate that living land snails exhibit EMFs that can be transmitted through their exoskeleton and can be detected utilizing a mixture of fine iron particles and Prussian Blue Stain (PBS Fe2). ...

A case-control study of radio frequency electromagnetic fields (RF-EMFs) and childhood leukemia was conducted in West Germany. The study region included municipalities near high-power radio and TV broadcast towers, including 16 amplitude-modulated and 8 frequency-modulated transmitters. Cases were aged 0-14 years, were diagnosed with leukemia between 1984 and 2003, and were registered at the Ge...

Electromagnetic fields (EMFs) are present throughout the modern world and are derived from many man-made sources including overhead transmission lines. The risks of extremely-low frequency (ELF) electromagnetic fields are particularly poorly understood especially at high field strengths as they are rarely encountered at ground level. Flying insects, however, can approach close to high field str...

Background: Recently, researchers have considered extremely low-frequency electromagnetic fields (ELF-EMFs), as one of the non-invasive therapies, in the treatment of many severe neurological disorders, including Alzheimer Disease (AD). AD is a progressive neurodegenerative disease characterized by the deposition of amyloid plaques in the brain. However, the increase in microglial cells increas...

For many years electromagnetic fields (EMFs) have been used clinically with various settings as an exogenous stimulation method to promote fracture healing. However, underlying mechanisms of action and EMF parameters responsible for certain effects remain unclear. Our aim was to investigate the influence of defined EMFs on human osteoblasts' and osteoclasts' viability and function. Primary huma...

introduction: the effects of electromagnetic fields on biological organisms have been a controversial and also interesting debate over the past few decades, despite the wide range of investigations, many aspects of extremely low frequency electromagnetic fields (elf/emfs) effects including mechanism of their interaction with live organisms and also their possible biological applications still r...

The aims of this study were to test the theory that transduction of low-level electromagnetic fields (EMFs) is mediated like other stimuli, and to determine the false-negative rate of the method used to assess the occurrence of transduction (intra-subject comparison of stimulus and non-stimulus states (ICOS)). A light stimulus was chosen as a basis of comparison because light could be applied a...

OBJECTIVE We sought direct evidence that acute exposure to environmental-strength electromagnetic fields (EMFs) could induce somatic reactions (EMF hypersensitivity). METHODS The subject, a female physician self-diagnosed with EMF hypersensitivity, was exposed to an average (over the head) 60-Hz electric field of 300 V/m (comparable with typical environmental-strength EMFs) during controlled ...

Although there is no certain known mechanism of how the electromagnetic fields (EMFs) at power frequency (50/60 Hz) can affect human health, it has been epidemiologically shown that they have many hazards on human health. Also the power frequency fields may interfere with the nearby electrical and electronic equipment. In response to the precautionary principle, it might be needed in some situa...
