Available in PDF, EPUB and Kindle. Book excerpt: Action potentials were recorded at four positions from frog sciatic nerves exposed to a constant magnetic field of 11.6 kilo-oersted. External electrodes arranged in pairs on segments of nerve oriented both parallel and perpendicular to the field permitted conduction velocity measurements to be expressed as a function of field orientation. An increase in conduction velocity was observed to be orientation dependent as was a latent period in its appearance. An aftereffect was noted that persisted to the end of the experiments. Possible mechanisms of action of the field are discussed in terms of current theories of impulse propagation. (Author).

Download or read book Possible Health Effects of Exposure to Residential Electric and Magnetic Fields written by National Research Council and published by National Academies Press. This book was released on 1997-03-18 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can the electric and magnetic fields (EMF) to which people are routinely exposed cause health effects? This volume assesses the data and draws conclusions about the consequences of human exposure to EMF. The committee examines what is known about three kinds of health effects associated with EMF: cancer, primarily childhood leukemia; reproduction and development; and neurobiological effects. This book provides a detailed discussion of hazard identification, dose-response assessment, exposure assessment, and risk characterization for each. Possible Health Effects of Exposure to Residential Electric and Magnetic Fields also discusses the tools available to measure exposure, common types of exposures, and what is known about the effects of exposure. The committee looks at correlations between EMF exposure and carcinogenesis, mutagenesis, neurobehavioral effects, reproductive and developmental effects, effects on melatonin and other neurochemicals, and effects on bone healing and stimulated cell growth.

This book was released on 2013-03-09 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors are pleased to present these Proceedings of the V Course of the "International School of Radiation Damage and Pro tection" of the "E. Majorana Centre", held in Erice (Italy) in No vember 1983. The lectures and discussions among leading scientists in various disciplines of physics, engineering, biophysics, cellular biology, physiology and medicine from 11 countries are included in this compilation. In this volume we have attempted to explore all aspects of the interaction of static and Extremely Low Frequency (ELF: 0-300 Hz) electric and magnetic fields with biological tissue, systems and whole organisms; we considered dosimetry and what is known or pre sumed concerning basic interactions, responses from the cellular and molecular level to the whole organism. Discussions of medical appli cations as well as epidemiologic investigations related to high volt age transmission were held with critiques of methodologies used and recommendations for future approaches. Consideration was also given to the necessity and principles of setting protection standards for man and the environment. We believe this is the first attempt to put all this informa tion together into one volume to provide perspective for understand ing the influence of static and ELF electric and magnetic fields on biological systems. We hope our attempts were successful. Martino Grandolfo Sol M. Michaelson Alessandro Rindi v ACKNOWLEDGEMENTS This is the Fifth Course of the International School of Radia tion Damage and Protection of the "Ettore Majorana" Centre for Sci entific Culture directed by Professor A.

Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes the emerging topic about the effects of SMF on biological samples ranging from single molecules, subcellular compartments, and cells to whole organisms. It also discusses the potential application of SMF in clinical treatment of cancer, pain, diabetes and other diseases. With the development and growing popularity of modern appliances like MRI in hospitals, the potential impact of magnetic fields on human health is invoking increasing concerns. At the same time, SMF has been explored in the treatment of tumor and other diseases for decades. Nevertheless, there are still some reservations and uncertainties about these treatments, which are largely due to the differential biological effects reported in the literature. These experimental inconsistencies are mainly caused by variations such as different magnetic field types, intensities, treatment time, as well as biological samples examined. The second edition added eight new chapters about new progress in this field including impacts of SMFs, magnetism of biomolecules, and potential of SMFs in the management of bone, pain, diabetes, and immune systems. This volume will help clarify some dilemmas in this field and encourage further investigations in order to achieve a better understanding of the biological effects of SMF, aiming for a rational application of SMF in clinical therapy in the near future. The book is useful for scientists, doctors, and students who are interested in magnetic fields and life sciences

This book was released on 2007-07-23 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Symposium on Biological Effects of Magnetic and Electrom- netic Fields was held from September 3-4, 1993 at Kyushu University in Fukuoka . Japan . Originally, it was only intended to be an informal gathering of many scientists who had accepted my invitation to visit Kyushu University after the XXIVth General Assembly of the International Union of Radio Science (URSI), held in Kyoto prior to our symposium . However, since so many distinguished scientists were able to come, it was decided that a more formal symposium would be possible . It was a very productive symposium and, as a result, many of the guests consented that it would be a good idea to gather all the information put forth at the meeting and have it published. In addition, although they were unfortunately unable to attend the symposium . many other distinguished scientists had also expressed their wish to contribute to this effort and, in so doing. help to increase understanding in this, as yet, relatively immature field of science . The question of both positive and negative effects of magnetic and electromagnetic fields on biological systems has become more and more important in our world today as they .
Download or read book Electromagnetic Interaction with Biological Systems written by James Lin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the early 1940's, electromagnetic energy in the nonionizing spectrum has contributed to the enhanced quality of life in a variety of ways. Aside from their well-known roles in communication, entertainment, industry and science, electromagnetic energy has come into wide spread use in biology and medicine. In addition to the intended purposes, these energies produce other effects which have been shown to influence the life processes of living organisms. It is noteworthy that these energies are not only harmless in ordinary quantities but are actually necessary for modern life, indeed without which life as we know it would be impossible. The purpose of this book is to present a succinct summary of the interaction of electromagnetic fields and waves with biological systems as they are now known. The subject matter is interdisciplinary and is based primarily on presentations scheduled for a joint symposium at the XXII General Assembly of the International Union of Radio Science, held in Tel Aviv, Israel from Tuesday, August 25 to Wednesday, September 2, 1987. The symposium was jointly sponsored by the Bioelectromagnetics Society in cooperation with the International Radiation Protection Association. The choice of topics was made to facilitate the application and to stimulate the use of nonioni zing electromagnetic energy in biology and medicine, and to increase the awareness and to promote the consideration of radiation safety by electrical engineers and experimental physicists.
