The interaction of electromagnetic fields (EMF) with living organisms presents an increasing source of interest nowadays. There are reports on the influence of EMFs on memory. In this study, the effect of a 50 Hz, 50G EMF was investigated on passive avoidance learning in male rats. For this purpose, male Wistar rats (n = 50, 6-8 weeks, 250-300 g) were randomly divided into five groups. Control ...
The effects of electromagnetic fields (EMFs) radiation at the frequency of 940 MHz on the structure and function of human adult and fetal hemoglobin (HbA and HbF) were studied. After extraction and purification of HbA and HbF, the oxygen absorption values for exposed and unexposed HbA and HbF to EMF were compared. The slope of oxygen absorption curve for exposed HbA was increased while that for...
With the widespread use of radio-frequency devices, it is increasingly important to understand the biological effects of the associated electromagnetic fields. Thus, we investigated the effects of radio-frequency electromagnetic fields (RF-EMF) on T cell responses during development due to the lack of science-based evidence for RF-EMF effects on developmental immune systems. Sprague Dawley (SD)...
Abstract A multiphase study was performed to find an effective method to evaluate electromagnetic field (EMF) sensitivity of patients. The first phase developed criteria for controlled testing using an environment low in chemical, particulate, and EMF pollution. Monitoring devices were used in an effort to ensure that extraneous EMF would not interfere with the tests. A second phase involved a ...
The term "electromagnetic fields" (EMF) is a combination of electric and magnetic fields as a diagnostic method as well as a therapeutic tool with many advantages such as ease of operation and painlessness, very controllable, which today has found wide application in regenerative medicine and also cancer treatment. In addition to organs such as nerves, hearts, and bones that have an electrica...
Background: Extremely low frequency (0-300 Hz) fields from power lines, electronic equipment and medical devices, have been reported to produce various biological effects. Global system for mobile (GSM) is most largely used in everybody's life. This system utilizes a low frequency band as well as a high frequency range of electromagnetic field. This study investigated the effects of 217 Hz elec...
This review paper, takes into account previously published papers based on human exposure to electromagnetic fields which is radiated from cellular base stations and its corresponding adverse effects on human beings. This paper reviews the estimation and evaluation of the human exposure to electromagnetic fields (EMF); these radiated fields from cellular base stations which aim to verify the ex...
Interest in electromagnetic field (EMF) treatments has increased rapidly in recent years due to its advantages over other treatments for tissue healing and infection. Benefits include low-cost, ready availability, ease of localized application, few if any sideeffects, and indefinite shelf life. Immunological studies show that low-intensity EMF can interact with cells and tissues, providing a la...
OBJECTIVES The objectives of this study were to assess whether people who report hypersensitivity to weak electromagnetic fields (EMFs) are better at detecting EMF under blind or double-blind conditions than nonhypersensitive individuals, and to test whether they respond to the presence of EMF with increased symptom reporting. METHODS An extensive systematic search was used to identify releva...
background: indisputable population exposure to widespread electromagnetic fields, has grown concerns over the probable health effects of these fields. objective: the present study was aimed to examine the possible effects of 50 hz extremely low frequency electromagnetic field (elf-emf) exposure on the number and quality of mice blastocysts. materials and methods: in present study, 66 nmri preg...
