  1. Magnetic fields generated by an induction heating (IH) cook top do not cause genotoxicity in vitro.

    Bioelectromagnetics 28(7):529 (2007) PMID 17492656

    The use of induction heater (IH) cook tops in homes has become widespread, especially in Japan, but there are concerns about the safety of intermediate frequency (IF) electromagnetic fields associated with these cooking appliances. Since the cellular genotoxicity of IF magnetic fields has not be...

    Bioelectromagnetics 28(7):577 (2007) PMID 17657732

    A wide variety of behaviors in several species has been statistically associated with the natural variations in geomagnetism.

A novel system that integrates pulsed electromagnetic fields (PEMFs) and bioreactors was applied to bone tissue ...
  5. Expression of HSP72 after ELF-EMF exposure in three cell lines.

    Bioelectromagnetics 28(7):509 (2007) PMID 17508393

    It has been reported that magnetic fields with flux densities ranging from microT to mT are able to induce heat shock factor, HSP72 mRNA or heat shock proteins in various cells. In this study we investigated changes in the HSP72 mRNA transcription level in three cell lines (HL-60, H9c2, and Gira...
  6. Investigation of protein expression in magnetic field-treated human glioma cells.

    Bioelectromagnetics 28(7):546 (2007) PMID 17570505

    We previously reported phenotypic changes in human breast cancer cells following low-level magnetic field (MF) exposure. Here proteomic methods were used to investigate the biochemical effect of MF exposure in SF767 human glioma cells. Protein alterations were studied after exposure to 1.2 micro...
  7. Lack of promoting effects of chronic exposure to 1.95-GHz W-CDMA signals for IMT-2000 cellular system on development of N-ethylnitrosourea-induced central nervous system tumors in F344 rats.

    Bioelectromagnetics 28(7):562 (2007) PMID 17516507

    The present study was performed to evaluate effects of a 2-year exposure to an electromagnetic near-field (EMF) equivalent to that generated by cellular phones on tumor development in the central nervous system (CNS) of rats. For this purpose, pregnant F344 rats were given a single administratio...
  8. Ornithine decarboxylase activity of L929 cells after exposure to continuous wave or 50 Hz modulated radiofrequency radiation--a replication study.

    Bioelectromagnetics 28(7):501 (2007) PMID 17508405

    A replication study with some extensions was made to confirm enhancement of ornithine decarboxylase (ODC) activity in murine L929 fibroblasts after radiofrequency (RF) field exposure reported in earlier studies. L929 cells purchased from two cell banks were exposed for 2, 8, or 24 h to continuou...
  9. Effects of high frequency electromagnetic field (EMF) emitted by mobile phones on the human motor cortex.

    Bioelectromagnetics 28(7):553 (2007) PMID 17516508

    We investigated whether the pulsed high frequency electromagnetic field (EMF) emitted by a mobile phone has short term effects on the human motor cortex. We measured motor evoked potentials (MEPs) elicited by single pulse transcranial magnetic stimulation (TMS), before and after mobile phone exp...
  10. Potential exposure assessment errors associated with body-worn RF dosimeters.

    Bioelectromagnetics 28(7):573 (2007) PMID 17654534

    Personal exposure meters for assessing exposure to RF electric or magnetic fields are subject to errors associated with perturbations of the fields by the presence of the human body. Although these alterations are complex they are not completely unpredictable. This article concludes that this er...
  11. Development and evaluation of intermediate frequency magnetic field exposure system for studies of in vitro biological effects.

    Bioelectromagnetics 28(7):538 (2007) PMID 17570495

    We have developed an intermediate frequency (IF) magnetic field exposure system for in vitro studies. Since there are no previous studies on exposure to heating-frequency magnetic fields generated from an induction heating (IH) cook top, there is a strong need for such an exposure system and for...
  12. Measuring ELF fields produced by mobile phones and personal digital assistants (PDAs).

    Bioelectromagnetics 28(7):580 (2007) PMID 17620301

  13. The effect of GSM and TETRA mobile handset signals on blood pressure, catechol levels and heart rate variability.

    Bioelectromagnetics 28(6):433 (2007) PMID 17486598

    An acute rise in blood pressure has been reported in normal volunteers during exposure to signals from a mobile phone handset. To investigate this finding further we carried out a double blind study in 120 healthy volunteers (43 men, 77 women) in whom we measured mean arterial pressure (MAP) dur...
  14. Neurophysiological effects of mobile phone electromagnetic fields on humans: a comprehensive review.

    Bioelectromagnetics 28(6):415 (2007) PMID 17503518

    In recent years a growing number of people have begun to use mobile phone technology. This phenomenon has raised questions and doubts about possible effects on users' brains. This literature review focuses on the human electrophysiological and neuro-metabolic effects of mobile phone (MP)-related...
  15. Assessing the numerical accuracy of the impedance method.

    Bioelectromagnetics 28(6):454 (2007) PMID 17486604

    The impedance method has been used extensively to calculate induced electric fields and currents in tissue as a result of applied electromagnetic fields. However, there has previously been no known method for an a priori assessment of the numerical accuracy of the results found by this method. H...
