  • Interaction of Extremely-Low-Frequency electromagnetic fields with living systems
    1991
    Co-Authors: T.s. Tenforde
    Abstract:

    The sources and physical properties of Extremely-Low-Frequency (ELF) electromagnetic fields are described in this paper. Biological effects and mechanisms through which ELF fields interact with humans and other organisms are discussed, including several aspects of this subject that are presently under active laboratory investigation. Studies on the potential health effects of ELF fields present in the home and workplace are also summarized, including a critical evaluation of evidence for a possible linkage between exposure to ELF fields and cancer risk. 53 refs.

  • Biological interactions of Extremely-Low-Frequency electric and magnetic fields
    Journal of Electroanalytical Chemistry, 1991
    Co-Authors: T.s. Tenforde
    Abstract:

    Abstract A description is given of the fundamental physical properties of Extremely-Low-Frequency (ELF) electromagnetic fields, and the mechanisms through which these fields interact with the human body at a macroscopic level. Evidence is presented that cell membranes play an important role in transducing ELF signals. Both experimental evidence and theoretical models are described that relate pericellular currents and electrochemical events at the outer membrane surface to transmembrane signaling pathways and cytoplasmic responses. Biological responses to ELF fields at the tissue, cellular and molecular levels are summarized, including new evidence that ELF field exposure produces alterations in messenger RNA synthesis, gene expression and the cytoplasmic concentrations of specific proteins.

  • oxidative dna damage in rats exposed to Extremely Low Frequency electro magnetic fields
    Free Radical Research, 2005
    Co-Authors: Beran Yokus, Dilek Ulker Cakir, Zulkuf M Akdag, Cemil Sert, Nuriye Mete
    Abstract:

    Extremely Low Frequency (ELF) electromagnetic field (EMF) is thought to prolong the life of free radicals and can act as a promoter or co-promoter of cancer. 8-hydroxy-2′-deoxyguanosine (8OHdG) is one of the predominant forms of radical-induced lesions to DNA and is a potential tool to asses the cancer risk. We examined the effects of Extremely Low Frequency electro magnetic field (ELF-EMF) (50 Hz, 0.97 mT) on 8OHdG levels in DNA and thiobarbituric acid reactive substances (TBARS) in plasma. To examine the possible time-dependent changes resulting from magnetic field, 8OHdG and TBARS were quantitated at 50 and 100 days. Our results showed that the exposure to ELF-EMF induced oxidative DNA damage and lipid peroxidation (LPO). The 8OHdG levels of exposed group (4.39±0.88 and 5.29±1.16 8OHdG/dG.105, respectively) were significantly higher than sham group at 50 and 100 days (3.02±0.63 and 3.46±0.38 8OHdG/dG.105) (p<0.001, p<0.001). The higher TBARS levels were also detected in the exposure group both on 50 an...
