Environmental Illness
A polysymptomatic condition believed by clinical ecologists to result from immune dysregulation induced by common foods, allergens, and chemicals, resulting in various physical and mental disorders. The medical community has remained largely skeptical of the existence of this "disease", given the plethora of symptoms attributed to environmental illness, the lack of reproducible laboratory abnormalities, and the use of unproven therapies to treat the condition. (From Segen, Dictionary of Modern Medicine, 1992)
Multiple Chemical Sensitivity

The application, via IMPLANTED ELECTRODES, of short bursts of electrical energy in the radiofrequency range, interspersed with pauses in delivery of the current long enough to dissipate the generated heat and avoid heat-induced tissue necrosis.
Fractures, Ununited
A fracture in which union fails to occur, the ends of the bone becoming rounded and eburnated, and a false joint occurs. (Stedman, 25th ed)
Pseudarthrosis
A pathologic entity characterized by deossification of a weight-bearing long bone, followed by bending and pathologic fracture, with inability to form normal BONY CALLUS leading to existence of the "false joint" that gives the condition its name. (Dorland, 27th ed)

Effect of magnetic field exposure on anchorage-independent growth of a promoter-sensitive mouse epidermal cell line (JB6). (1/1506)

The anchorage-independent growth of mouse epidermal cells (JB6) exposed to 60-Hz magnetic fields (MF) was investigated. Promotion-responsive JB6 cells were suspended in agar (10(4)cells/plate) and exposed continuously to 0.10 or 0.96 mT, 60-Hz magnetic fields for 10-14 days, with or without concurrent treatment with the tumor promoter tetradecanoylphorbol acetate (TPA). Exposures to MF were conducted in a manner such that the experimenter was blind to the treatment group of the cells. At the end of the exposure period, the anchorage-independent growth of JB6 cells on soft agar was examined by counting the number of colonies larger than 60 microm (minimum of 60 cells). The use of a combined treatment of the cells with both MF and TPA was to provide an internal positive control to estimate the success of the assay and to allow evaluation of co-promotion. Statistical analysis was performed by a randomized block design analysis of variance to examine both the effect of TPA treatment (alone and in combination with MF exposure) and the effect of intra-assay variability. Transformation frequency of JB6 cells displayed a dose-dependent response to increasing concentrations of TPA. Coexposure of cells to both TPA and 0.10 or 0.96 mT, 60-Hz MF did not result in any differences in transformation frequency for any TPA concentrations tested (0-1 ng/ml). These data indicate that exposure to a 0.10 or 0.96 mT, 60-Hz MF does not act as a promoter or co-promoter in promotion-sensitive JB6 cell anchorage-independent growth.  (+info)

Transmembrane calcium influx induced by ac electric fields. (2/1506)

Exogenous electric fields induce cellular responses including redistribution of integral membrane proteins, reorganization of microfilament structures, and changes in intracellular calcium ion concentration ([Ca2+]i). Although increases in [Ca2+]i caused by application of direct current electric fields have been documented, quantitative measurements of the effects of alternating current (ac) electric fields on [Ca2+]i are lacking and the Ca2+ pathways that mediate such effects remain to be identified. Using epifluorescence microscopy, we have examined in a model cell type the [Ca2+]i response to ac electric fields. Application of a 1 or 10 Hz electric field to human hepatoma (Hep3B) cells induces a fourfold increase in [Ca2+]i (from 50 nM to 200 nM) within 30 min of continuous field exposure. Depletion of Ca2+ in the extracellular medium prevents the electric field-induced increase in [Ca2+]i, suggesting that Ca2+ influx across the plasma membrane is responsible for the [Ca2+]i increase. Incubation of cells with the phospholipase C inhibitor U73122 does not inhibit ac electric field-induced increases in [Ca2+]i, suggesting that receptor-regulated release of intracellular Ca2+ is not important for this effect. Treatment of cells with either the stretch-activated cation channel inhibitor GdCl3 or the nonspecific calcium channel blocker CoCl2 partially inhibits the [Ca2+]i increase induced by ac electric fields, and concomitant treatment with both GdCl3 and CoCl2 completely inhibits the field-induced [Ca2+]i increase. Since neither Gd3+ nor Co2+ is efficiently transported across the plasma membrane, these data suggest that the increase in [Ca2+]i induced by ac electric fields depends entirely on Ca2+ influx from the extracellular medium.  (+info)

A 50-Hz electromagnetic field impairs sleep. (3/1506)

In view of reports of health problems induced by low frequency (50-60 Hz) electromagnetic fields (EMF), we carried out a study in 18 healthy subjects, comparing sleep with and without exposure to a 50 Hz/1 mu Tesla electrical field. We found that the EMF condition was associated with reduced: total sleep time (TST), sleep efficiency, stages 3 + 4 slow wave sleep (SWS), and slow wave activity (SWA). Circulating melatonin, growth hormone, prolactin, testosterone or cortisol were not affected. The results suggest that commonly occurring low frequency electromagnetic fields may interfere with sleep.  (+info)

Metal detector and swallowed metal foreign bodies in children. (4/1506)

OBJECTIVE: To evaluate a metal detector to diagnose swallowed radio-opaque metal foreign bodies (MFBs) in children, and whether they can detect non-radio-opaque MFBs. METHODS: In a prospective study, 231 children, who presented to the accident and emergency department with a history of swallowing MFBs, were evaluated by the metal detector as well as radiography to confirm and locate the presence or absence of MFBs. RESULTS: A definite history of swallowing a MFB by the child was given by 186 (81%) parents. The metal detector located MFBs in 183 children and radiographs confirmed radio-opaque MFBs in 181. In the remaining 45 (19%), when swallowing was suspected and not definite, both metal detector and radiography confirmed the presence of a MFB in only four. CONCLUSION: A high detection rate of swallowed MFBs was observed in this study, using a metal detector. It is also of value to detect non-radio-opaque MFBs like aluminium. The detection of MFBs is high when the history of swallowing is definite.  (+info)

Demonstration of the parity-violating energy difference between enantiomers. (5/1506)

Racemic mixtures of (+) and (-) sodium potassium tartrate, tris(1, 2-ethanediamine)cobalt(III), and tris(1,2-ethanediamine)iridium(III) molecules were crystallized, and the optical activities of the resulting crystalline materials, dissolved in water, were carefully measured to study the influence of the parity-violating energy difference in the crystallization process. Although no effect was found in the case of tartrate, enantiomeric excess appeared in the crystallization of the cobalt and iridium complexes. These investigations, performed in our laboratory, demonstrated the contribution of the parity-violating neutral weak current to the forces acting in molecules.  (+info)

A small, physiological electric field orients cell division. (6/1506)

We report on an observation that the orientation of cell division is directed by small, applied electric fields (EFs). Cultured human corneal epithelial cells were exposed to a direct-current EF of physiological magnitude. Cells divided while attached to the culture dish, and most did so with a cleavage plane perpendicular to the EF vector. There are many instances in which cell divisions in vivo occur in the presence of direct-current physiological EF, for example, during embryonic morphogenesis, neuronal and epithelial differentiation, wound healing, or tumor formation. Endogenous physiological EFs may play important roles in some or all of these processes by regulating the axis of cell division and, hence, the positioning of daughter cells.  (+info)

Power-frequency electric and magnetic fields and risk of childhood leukemia in Canada. (7/1506)

In a case-control study of childhood leukemia in relation to exposure to power-frequency electric and magnetic fields (EMF), 399 children resident in five Canadian provinces who were diagnosed at ages 0-14 years between 1990 and 1994 (June 1995 in British Columbia and Quebec) were enrolled, along with 399 controls. Exposure assessment included 48-hour personal EMF measurement, wire coding and magnetic field measurements for subjects' residences from conception to diagnosis/reference date, and a 24-hour magnetic field bedroom measurement. Personal magnetic fields were not related to risk of leukemia (adjusted odds ratio (OR) = 0.95, p for trend = 0.73) or acute lymphatic leukemia (OR = 0.93, p for trend = 0.64). There were no clear associations with predicted magnetic field exposure 2 years before the diagnosis/reference date or over the subject's lifetime or with personal electric field exposure. A statistically nonsignificant elevated risk of acute lymphatic leukemia was observed with very high wiring configurations among residences of subjects 2 years before the diagnosis/reference date (OR = 1.72 compared with underground wiring, 95% confidence interval 0.54-5.45). These results provide little support for a relation between power-frequency EMF exposure and risk of childhood leukemia.  (+info)

Lack of effect of a 60 Hz magnetic field on biomarkers of tumor promotion in the skin of SENCAR mice. (8/1506)

It has been proposed that extremely low frequency magnetic fields may enhance tumorigenesis through a co-promotional mechanism. This hypothesis has been further tested using the two-stage model of mouse skin carcinogenesis, i.e. 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced promotion of skin carcinogenesis in mice initiated by a single subcarcinogenic dose of 7,12-dimethylbenz[a]anthracene. Experimentation utilized three different doses of TPA within its dose-response range (0.85, 1.70 or 3.40 nmol) and examined the following early biomarkers of tumor promotion after 1, 2 and 5 weeks of promotion: increases in epidermal thickness and the labeling index of epidermal cells, induction of epidermal ornithine decarboxylase activity and down-regulation of epidermal protein kinase C activity. Mice exposed to a 60 Hz magnetic field having a flux density of 2 mT for 6 h/day for 5 days/week were compared with mice exposed to an ambient magnetic field. Within the sensitivity limits of the biomarker methodology and the exposure parameters employed, no consistent, statistically significant effects indicative of promotion or co-promotion by the magnetic field were demonstrated.  (+info)

All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and then reared for 60 days. The obtained results revealed that all growth indices were significantly (p | 0.05) improved by increasing in the EMFs intensity. 2 mT treatment indicated the highest final weight (43.95 ± 0.27 g), weight gain (6.83 ± 0.10 g), weight gain rate (20.94 ± 0.13 %), daily growth rate (0.38 ± 0.00 g day-1), specific growth rate (1.26 ± 0.01 % day-1) and the lowest food conversion ratio (p | 0.05).

Occupational exposure assessment for power frequency electromagnetic fields - KFUPM ePrintsOccupational exposure assessment for power frequency electromagnetic fields - KFUPM ePrints
Exposure assessment is the determination or estimate of the magnitude, frequency of occurrence, and rate of exposure of an individual or a group to an environmental agent. The agents of interest in this case are the electric and magnetic fields (EMF) in the extreme low-frequency range that includes the power frequency of 50/60 Hz. There are an increasing concern that exposure to EMF may be associated with biological and health effects. This concern has prompted numerous measurement projects and the development of instrumentation, methodologies, and exposure models and simulations. This paper identifies the status of EMF exposure assessment research related to occupational exposures. It draws the recent results to emphasize the unique aspects of EMF exposures in the home and utilities environments, and highlights the research needs. The intensities of electromagnetic fields have been measured under power transmission and distribution lines, at substations and industrial plants and near various ...

The multipotent action of electromagnetic field : BiologiaThe multipotent action of electromagnetic field : Biologia
The use of electromagnetic field in the treatment of diseases has already been known for centuries. Low hazard, wide applicability, good clinical effect and the relatively low cost enable the electromagnetic field therapy to be widely used. The biological effect of the electromagnetic field is based on inter alia, analgesic, anti-inflammatory, osteogenetic and regenerative actions, which are associated with the changes in cellular signal transmission, action on biological membranes, ion transport processes, protein synthesis, cell proliferation and apoptosis. In addition, the electromagnetic field increases quantity of collagen content elevating its density and a more regular arrangement. Furthermore, it induces the activation of glutathione peroxidase and intensification of the process of erythropoiesis leading to better use of oxygen in the tissues around the wound.

Effects of Low Frequency Magnetic Field on Exercise Induced Angina - Full Text View - ClinicalTrials.govEffects of Low Frequency Magnetic Field on Exercise Induced Angina - Full Text View - ClinicalTrials.gov
Several studies have shown that low frequency electromagnetic field has biological and therapeutic potential on the human body, however, to very limited extent on the heart. In the current study cardiac patients suffering from exercise-induced-angina will undergo two consecutive stress tests, one test after being exposed for 30 minutes to the magnetic field and the other test after being exposed to placebo (magnetic field not operated). The order of which the magnet will be operated will be randomly assigned for the patients so a group of patients will be exposed to the magnetic field at their first stress test and another groups of patients will be exposed to the magnetic field at their second stress test. During resting period, and while the patients are subjected to the magnetic field, a 12 lead electrocardiogram (ECG) will be monitored. Thereafter the magnetic field and frequency will be turned off and the patients will be subjected to graded exercise stress test during which they will be ...

Young adult long-term study: Beneficial cognitive effects of chronic EMF exposure were observed in both Tg and NT mice. EMF exposure had essentially no effect on oxidative markers in the hippocampus of Tg mice, and the changes in oxidative markers in NT mice can be interpreted as a decrease in oxidative stress. No effect of EMF exposure on any oxidative markers was observed in the cerebral cortex tissue of either NT or Tg mice. An increase in levels of soluble Aβ in both hippocampus and frontal cortex was detected in EMF-exposed Tg mice. Aged adult long-term study:No effect of EMF exposure on cognitive performance of cognitively impaired Tg mice was observed during the initial 5 months of EMF exposure, while NT mice showed improved performance on cognitive testing 5 months after exposure initiation. After 8 months of EMF exposure the cognitive performance of EMF-exposed Tg mice was considerably better. Exposed NT mice continued to show better cognitive performance compared to the control NT ...

A novel exposure system for double-blind human electromagnetic provocation studies has been developed that satisfies the precision, control of fields and potential artifacts, and provides the flexibility to investigate the response of hypotheses-driven electromagnetic field exposure schemes on brain function, ranging from extremely low frequency (ELF) to radio frequency (RF) fields. The system can provide the same exposure of the lateral cerebral cortex at two different RF frequencies (900 and 2140 MHz) but with different exposure levels at subcortical structures, and also allows uniform ELF magnetic field exposure of the brain. The RF modulation and ELF signal are obtained by a freely programmable arbitrary signal generator allowing a wide range of worst-case exposure scenarios to be simulated, including those caused by wireless devices. The maximum achievable RF exposure is larger than 60 W/kg peak spatial specific absorption rate averaged over 10 g of tissue. The maximum ELF magnetic field ...

Low frequency electromagnetic wave propagation in 3D plasma configurations - RERO DOCLow frequency electromagnetic wave propagation in 3D plasma configurations - RERO DOC
We investigate low-frequency electromagnetic wave propagation and absorption properties in 2D and 3D plasma configurations. For these purposes, we have developed a new full-wave 3D code LEMan that determines a global solution of the wave equation in bounded stellarator plasmas excited with an external antenna. No assumption on the wavelength compared to the plasma size is made, all the effects of the 3D geometry and finite plasma extent are included. The equation is formulated in terms of electromagnetic potentials in order to avoid numerical pollution effects. The code utilises linear and Hermite cubic finite element discretisation in the radial direction and Fourier series in the poloidal and toroidal variables. The full cold plasma model including finite electron inertia and, thus, mode conversion effects is implemented. The code uses Boozer magnetic coordinates and has an interface to the TERPSICHORE code. Special care is taken to treat the magnetic axis and to ensure the unicity of the numerical

A few studies concentrated on the effects of electrical (power frequency) electromagnetic fields (EMFs) on the human brain function and nervous system (Savitz et al., 1998; Hakansson et al., 2003, Feychting et al., 2003; Qiu et al., 2004). These studies clearly established that there is a strong and consistent relationship between exposure to electrical EMFs and various types of neurodegenerative diseases like Alzheimers disease, Parkinsons disease, motor neuron disease and amyotrophic lateral sclerosis (ALS) or Lou Gehrigs disease. ALS is also a type of motor neuron disease. The studies of Savitz, Hakansson and Feychting furnish ample evidence on the relationship between electrical EMF exposure and Alzheimers disease, while the study by Hakansson proves the relationship between exposure of electrical EMFs and ALS. Various other studies had also confirmed the link between electrical EMF exposure and ALS and Alzheimers disease (Johansen, 2000, 2001, 2004; Ahlbom, 2001; Park et al., ...

Whither the bees? - WeeksMDWhither the bees? - WeeksMD
Microwave and other low frequency electromagnetic fields (EMFs) have been shown to act by activating voltage-gated calcium channels (VGCCs) with most biological effects being due to elevated intracellular calcium, consequent nitric oxide (NO) elevation and either peroxynitrite or NO signaling. This, the role of excessive intracellular calcium in microwave effects, the greater biological effects of pulsed fields and some 20,000 papers on microwave biological effects show that the current international safety standards do not predict biological hazard. Such standards are based on the false assumption that the predominant effects of microwave and other low frequency EMF exposures are due to heating. A whole series of biological changes reportedly produced by microwave exposures can now be explained in terms of this new paradigm of EMF action via VGCC activation, including: oxidative stress; single and double stranded breaks in cellular DNA; therapeutic effects; blood-brain barrier breakdown; ...

Nervous system manipulation by electromagnetic fields from monitors - Federal Jack
Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near 1/2 Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby computer monitor or TV set. For the latter, the image pulsing may be embedded in the program material, or it may be overlaid by modulating a video stream, either as an RF signal or as a video signal. The image displayed on a computer monitor may be pulsed effectively by a simple computer program. For certain monitors, pulsed electromagnetic fields capable of exciting sensory resonances in nearby subjects may be generated even as the displayed images are pulsed with subliminal intensity.. ...

Children are exposed to various kind of non-ionizan radiation in their daily life involuntarily. The potential sensitivity of developing organism to the effects of radiofrequency (RF) signals, the higher estimated specific absorption rate (SAR) values of children and greater lifetime cumulative risk raised the scientific interest for childrens vulnerability to electromagnetic fields (EMFs). In modern societies, children are being exposed to EMFs in very early ages. There are many researches in scientific literature investigating the alterations of biological parameters in living organisms after EMFs. Although the international guidelines did not report definite, convincing data about the causality, there are unignorable amount of studies indicating the increased risk of cancer, hematologic effects and cognitive impairment. Although they are less in amount; growing number of studies reveal the impacts on metabolism and endocrine function. Reproductive system and growth look like the most ...

Occupational magnetic field exposure among women in Stockholm County, Sweden | Occupational & Environmental MedicineOccupational magnetic field exposure among women in Stockholm County, Sweden | Occupational & Environmental Medicine
In this study we created a job-exposure matrix based on systematically performed magnetic field measurements in the 49 most common occupations among women in Stockholm County. We identified a group of occupations in which workers are exposed to higher than average magnetic field levels and spend a larger than average proportion of their time in high fields. Individual occupations showed large variation and overlap in measured magnetic field values. When exposure during 24 hours was taken into consideration the contrast between high and low exposure occupations was diluted but still discernible. Among the highest exposed were women working in kitchens and in shops, which comprises occupations that have not previously been identified as highly exposed to magnetic fields.. The main limitation of the study is the limited number of measurements in each occupation and that the subjects were all volunteers and thus not a random sample. To ensure representation the measurements were distributed within ...

Controversy over cell phones in trains. A letter from T. Hondou in the Journal of the Physical Society of Japan has been widely reported in newspapers. Hondou claims that the simultaneous use of a number of mobile phones in an area with a reflective boundary, such as a commuter train, could create a level of exposure to electromagnetic fields that could exceed the guidelines of the International Commission on Non-Ionizing Radiation Protection. Other experts dispute his conclusions. Some have pointed out that the author used calculations suited to far-field exposure rather than Specific Absorption Rate - appropriate for near-field exposure. In addition, it has been claimed that he underestimated the dissipation of electromagnetic fields that would occur in a train with many people inside..

Electromagnetic Radiation - Windows to the UniverseElectromagnetic Radiation - Windows to the Universe
Electromagnetic radiation is the result of oscillating electric and magnetic fields. The wave of energy generated by such vibrations moves through space at the speed of light. And well it should... for visible light is indeed one form of electromagnetic (EM) radiation.. X-rays, radio waves, gamma rays, and infrared and ultraviolet light are the other main types of electromagnetic radiation. They are all traveling vibrations of electromagnetic waves, each with its own characteristic wavelength. Organized in order of wavelength, they make up the electromagnetic spectrum.. Sometimes it is useful to think about electromagnetic radiation as though it came in packets. These packets of EM radiation are called photons.. There is a second main type of radiation, which is the result of subatomic particles moving at very high speeds. That type of radiation is called particle radiation.. ...

Pulsed ElectroMagnetic Field Therapy
Electromagnetic energy is the component that controls cell functions, therefore all bodily functions. When that energy is disrupted or taken away, your body is punished. The worry of harmful electromagnetic fields is widely known but PEMF therapy provides a safe, protective use of balancing frequencies to decrease the effects of negative electricity. Unlike magnetic frequencies, PEMF penetrates through the body at different strengths while not addicting the cells to require this energy. PEMF therapy is the best choice to help your body feel and work better so you can live your life to the fullest!. ...

Extensive Pulsed Electromagnetic Field research shows that PEMF therapy enables bone & connective tissue regeneration by enhancing growth & shortening rehabilitation.. Pulsed electromagnetic field therapy for bone stimulation & connective tissue regeneration is one of PEMFs first approved uses. PEMF therapy enhances regeneration of bone and connective tissue matrix. PERIOD. End of story. It ONLY fails where application parameters are faulty (or perhaps if someone has some sort of genetic anomaly).. Studies done that show no effect are red-herrings (poorly designed and meant to fail). PEMF have been repeatedly shown to reverse degenerative effects of osteoarthritis, rheumatoid arthritis and osteoporosis. The plethora of failures in the research can be largely-attributed to short duration PEMF application, or use of incorrect waveform, frequency, amplitude; or any combination of those..

Strange nature of electromagnetic force carriersStrange nature of electromagnetic force carriers
If carriers of electromagnetic force are photons, it also means that magnetic fields surrounding magnets are also composed of photons. I must confess that I am confused by this, especially as magnetic fields and its effects on matter do not show any similarity with light, which is a form of electromagnetic radiation, itself also made of photons. If both electromagnetic radiation and magnetic field are carried by photons, then why light doesn t cause a piece of iron to move around as magnetic field does. If it is made of photons, why photons of magnetic field don t excite electrons of atoms that they hit to higher energy level as photons of electromagnetic radiation do? Do photons comprising a magnetic field have a particular wavelength/frequency as photons of electromagnetic radiation do? Why are these same things, so strikingly different in their manifestations ...

3-D Displacement Measurement for Structural Health Monitoring Using Low-Frequency Magnetic Fields3-D Displacement Measurement for Structural Health Monitoring Using Low-Frequency Magnetic Fields
Smart structures of the future will require a cost-effective, easily deployable solution for structural health monitoring. High loads on structures cause stresses that may lead to expansion of gaps, which are of utmost importance when it comes to overall structural health, as they absorb excess stress. Existing methods for direct displacement measurement of expansion joints are not ideal, as they operate under line-of-sight assumptions, are sensitive to moisture, or employ moving parts. In addition, the majority of existing sensors for structural health monitoring are uniaxial, and hence are fundamentally unable to measure 3-D displacement. Importantly, none of the existing wireless sensors for structural health monitoring can be embedded in concrete. We propose a system that uses low-frequency magnetic fields to conduct 3-D displacement measurement directly from within concrete, with a median displacement error of 0.5 mm in all directions, with a maximum separation distance of 50 mm between the

Mutat Res. 2012 Aug 30;747(1):138-41. Tempol suppresses micronuclei formation in astrocytes of newborn rats exposed to 50-Hz, 10-mT electromagnetic fields under bleomycin administration. Miyakoshi Y1, Kajihara C, Shimizu H, Yanagisawa H. 1Department of Public Health and Environmental Medicine, the Jikei University School of Medicine, Tokyo, Japan. Abstract A number of epidemiological studies have suggested that exposure to environmental and occupational electromagnetic fields (EMFs) contribute to the induction of brain tumors. The aim of this study was to investigate the mutagenetic effects of co-exposure to 50-Hz, 10-mT EMFs and bleomycin (BLM) using an ex vivo newborn rat astrocyte micronucleus assay. We also investigated whether the mutagenetic effects of EMFs were related to active oxygen species by using 4-hydroxy-2,2,6,6-tetramethyl piperidine-1-oxyl (tempol), a superoxide radical scavenger. Three-day-old male Sprague-Dawley rats were co-exposed to 50-Hz EMFs and BLM (5 or 10mg/kg body weight (BW)

Cell Phones and Cancer Risk: Update | Business Ethics
Cell phones have only been in widespread use for a couple of decades, which is far too short a time for us to know conclusively whether or not using them could cause cancer. Research thus far appears to indicate that most of us have little if anything to worry about.. According to the federally funded National Cancer Institute, the low-frequency electromagnetic radiation that cell phones give off when we hold them up to our heads is non-ionizing, meaning it cannot cause significant human tissue heating or body temperature increases that could lead to direct damage to cellular DNA. By contrast, X-rays consist of high-frequency ionizing electromagnetic radiation and can lead to the kind of cellular damage resulting in cancer. Nonetheless, some cell phone users and researchers still worry about our cell phone usage, given how much we now use them and how little we know about their potential long-term effects.. The reason the issue keeps coming up is that some initial studies in Europe, where cell ...

Side effects of using PEMF therapy - Oxford PEMF
PEMF therapy also affects the utilization of nutrients and other medications in the body. For example, PEMF therapy is contraindicated for patients who are under chemotherapy. This is because PEMF therapy promotes cell growth and repair, and so it may promote the proliferation of cancer cells. Therefore, PEMF therapy has effects that are antagonistic to chemotherapeutic drugs. These side effects can be avoided by starting PEMF therapy after chemotherapy has been completed. However, there is more research that is required in this area as some studies suggest that PEMF therapy actually helps chemotherapeutic drugs achieve their objective.. Although there is still much more research to be done, pregnant women are advised to avoid PEMF because it is considered to be a teratogen. A teratogen is an agent or factor that causes poor, abnormal or inhibited development of unborn babies or embryos. Therefore, pregnant women should not be exposed to PEMF since it increases the risk of miscarriage, birth ...

Electromagnetic radiation - WikipediaElectromagnetic radiation - Wikipedia
Maxwells equations established that some charges and currents (sources) produce a local type of electromagnetic field near them that does not have the behaviour of EMR. Currents directly produce a magnetic field, but it is of a magnetic dipole type that dies out with distance from the current. In a similar manner, moving charges pushed apart in a conductor by a changing electrical potential (such as in an antenna) produce an electric dipole type electrical field, but this also declines with distance. These fields make up the near-field near the EMR source. Neither of these behaviours are responsible for EM radiation. Instead, they cause electromagnetic field behaviour that only efficiently transfers power to a receiver very close to the source, such as the magnetic induction inside a transformer, or the feedback behaviour that happens close to the coil of a metal detector. Typically, near-fields have a powerful effect on their own sources, causing an increased load (decreased electrical ...

We report the effects of pulsed electromagnetic fields (PEMFs) on the responsiveness of osteoclasts to cellular, hormonal, and ionic signals. Osteoclasts isolated from neonatal rat long bones were dispersed onto either slices of devitalised cortical bone (for the measurement of resorptive activity) or glass coverslips (for the determination of the cytosolic free Ca2+ concentration, [Ca2+]). Osteoclasts were also cocultured on bone with osteoblastlike, UMR-106 cells. Bone resorption was quantitated by scanning electron microscopy and computer-assisted morphometry. PEMF application to osteoblast-osteoclast cocultures for 18 hr resulted in a twofold stimulation of bone resorption. In contrast, resorption by isolated osteoclasts remained unchanged in the presence of PEMFs, suggesting that osteoblasts were necessary for the PEMF-induced resorption simulation seen in osteoblast-osteoclast cocultures. Furthermore, the potent inhibitory action of the hormone calcitonin on bone resorption was unaffected by PEMF
