Book Description
Magnetic Resonance in Biological Systems, Volume 9 is a collection of manuscripts presented at the Second International Conference on Magnetic Resonance in Biological Systems, held in Wenner-Gren Center, Stockholm, Sweden on June 1966. The conference is sponsored by International Union of Biochemistry Swedish Medical Research Council Swedish Natural Science Research Council Wenner-Gren Center Foundation for Scientific Research. This book contains 51 chapters, and begins with reviews of NMR investigations of biological macromolecules, including proteins, amino acids, and glycylglycine copper (II). Considerable chapters are devoted to numerous biological studies using the electronic paramagnetic resonance (EPR), thus introducing the branch of science called submolecular biology. This book also explores other applications of NMR and EPR, with special emphasis on blood component analysis and protein-metal complexes. The final chapters survey the principles and applications of Mössbauer spectroscopy. This book will prove useful to analytical chemists and biologists.

Book Description
Tom S. Tenforde A programma tic effort to assess the effects of magneticfield exposure on living organisms and man is under way at the Lawrence Berkeley Laboratory. This program, which is supported by the Division of Biomedical and Environmental Research of the U. S. Department of Energy, has three principal aspects. First, in a project for which I serve as the coordinator, a series of biophysical experiments are being carried out to determine magnetic field effects on molecular, cellular and whole-animal test systems. A second effort, headed by Dr. Thomas Budinger, involves epidemiological studies designed to evaluate potential health effects in groups of scientists and industrial workers who have been occupationally exposed to high magnetic fields. The third project is the establishment of magnetic field exposure guidelines by a six-member committee composed of scientists from through out the U. S. and headed by Dr. Edward Alpen, Director of the Lawrence Berkeley Laboratory Biology and Medicine Division. During the initial phase of this program, it became increasingly clear to all of the scientists involved that it would be a worthwhile effort to hold a Biomagnetic Effects Workshop. There were, in fact, three reasons underlying our decision to sponsor such a conference: First of alL more than a decade has passed since there was a large conference in the United States devoted exclusively to biomagnetic research.

Book Description
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.

Book Description
The Committee to Assess the Current Status and Future Direction of High Magnetic Field Science in the United States was convened by the National Research Council in response to a request by the National Science Foundation. This report answers three questions: (1) What is the current state of high-field magnet science, engineering, and technology in the United States, and are there any conspicuous needs to be addressed? (2) What are the current science drivers and which scientific opportunities and challenges can be anticipated over the next ten years? (3) What are the principal existing and planned high magnetic field facilities outside of the United States, what roles have U.S. high field magnet development efforts played in developing those facilities, and what potentials exist for further international collaboration in this area? A magnetic field is produced by an electrical current in a metal coil. This current exerts an expansive force on the coil, and a magnetic field is "high" if it challenges the strength and current-carrying capacity of the materials that create the field. Although lower magnetic fields can be achieved using commercially available magnets, research in the highest achievable fields has been, and will continue to be, most often performed in large research centers that possess the materials and systems know-how for forefront research. Only a few high field centers exist around the world; in the United States, the principal center is the National High Magnetic Field Laboratory (NHMFL). High Magnetic Field Science and Its Application in the United States considers continued support for a centralized high-field facility such as NHFML to be the highest priority. This report contains a recommendation for the funding and siting of several new high field nuclear magnetic resonance magnets at user facilities in different regions of the United States. Continued advancement in high-magnetic field science requires substantial investments in magnets with enhanced capabilities. High Magnetic Field Science and Its Application in the United States contains recommendations for the further development of all-superconducting, hybrid, and higher field pulsed magnets that meet ambitious but achievable goals.

Book Description
Life is controlled by chemistry. Chemistry is not the whole life but the life is totally chemistry. Chemistry is a key to biology. Nothing in biology can be understood without chemistry and chemical reactions. There are many factors controlling biochemical reactions, however the most intriguing is the magnetic field. The ability to respond to magnetic fields is ubiquitous and universal among the five kingdoms of organisms. Magneto-biology is a field of knowledge which considers phenomena accompanying the influence of magnetic fields, permanent and alternating, on the biological systems at all levels: molecular, cellular, and whole organism. There is no doubt that magnetic fields do the human health and feeling of well-being; the latter is a key factor stimulating both social and scientific interest in magneto-biology. This book considers numerous biological and biomedical effects of the two magnetic fields: internal fields created by magnetic nuclei, and external magnetic fields, both permanent and oscillating. It critically summarizes magnetic effects on the biological clocks, biological compass for orientation and navigation of migrating animals, the influence of cells phones on the health. It demonstrates magnetic and isotope effects on the food chains and metabolism, ecology and epidemiology. It explains the origin of trans-cranial magnetic stimulation of cognitive processes to prevent neurodegenerative disorders; it enlightens magnetic stimulation of the ATP synthesis and protein phosphorylation, magnetic control of the DNA synthesis and gene expression. It shows how magnetic fields can be used to eliminate ATP deficiency at cardiac diseases and how to use magnetic stable isotope ions as the medical agents against hypoxia and cardiac insufficiency, as a means for controlling cell proliferation and stimulating destruction and apoptosis of the cancer cells. The uniqueness of this book is that it is focused on the chemical biology and medicine, on the discovery and analysis of chemical magneto-dependent mechanisms. This book gives a collection of scattered information, its critical analysis, generalization and explanation of physics and chemistry of magneto-biological effects as a basis for the deliberate usage in medicine (for the trans-cranial magnetic stimulation of cognitive processes and genetics, in particular).

Book Description
People are immersed in electromagnetic fields from such sources as power lines, domestic appliances, mobile phones, and even electrical storms. All living beings sense electric fields, but the physical origins of the phenomenon are still unclear. Magnetobiology considers the effects of electromagnetic fields on living organisms. It provides a comprehensive review of relevant experimental data and theoretical concepts, and discusses all major modern hypotheses on the physical nature of magnetobiological effects. It also highlights some problems that have yet to be solved and points out new avenues for research. Why do some people feel unwell during a lightning storm? Why is there a correlation between the level of electromagnetic background and the incidence of cancer? Why do so many medical centers use electromagnetic exposures to treat a wide variety of disorders in humans? The international scientific community is extremely interested in a theory of magnetobiology and the answers to these and other questions, as evidenced by the growing number of research associations in the United States, Europe, and other parts of the world. The World Health Organization (WHO) has named electromagnetic contamination in occupational and residential areas as a stress factor for human beings. This book stands out among recent texts on magnetobiology because it draws on a strong foundation of empirical and theoretical evidence to explain the various effects of magnetic fields on the human body. It contains the first comprehensive collection of experimental data bearing physical information, frequency and amplitude/power spectra, and original research data on how electromagnetic fields interfere with ions and molecules inside the proteins of living organisms. - Introduction is written so that it will be understandable to a wide scientific community regardless of their specialisation - First comprehensive collection of experimental data bearing physical information, frequency and amplitude/power spectra - Original theoretical research data on the interference of ions and molecules inside proteins - Appendix covers physical questions most relevant for magnetobiology. In particular there is an original exposition of the magnetic resonance basic principles
