Book Description
Transmembrane signaling is one of the most significant cell biological events in the life and death of cells in general and lymphocytes in particular. Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world. This book handles both aspects of the signalling events, and in some cases tries to unify our concepts and help understand the signals that govern the life and death of our cells. Not only the understanding, but also the interference (e.g. medication) may depend on the full knowledge of both sides. These above statements are supported by the application of highly diverse physical and biochemical technologies demonstrated and explained by experts who are pioneers of their particular scientific field.

Book Description
Fluorescence spectroscopy has traditionally found wide application in bio chemistry and cell biology. Since there are relatively few naturally occurring fluorescent biomolecules, fluorescence spectroscopy offers a combination of great specificity and sensitivity. Historically, these features have been ex ploited with great success utilizing both intrinsic and extrinsic probes. Re cent applications have built upon these traditional strengths and have re sulted in the development of new instrumental techniques, novel and convenient fluorescent probes, and a deeper, theoretical understanding of fundamental processes. Frequently, fluorescence techniques are tailored to attack a specific biological problem. These new methods in turn produce new physical situations and phenomena which are often of interest to the physical chemist. Thus, progress in one area stimulates renewed interest in other areas. The goal of this book is to provide detailed monographs on the use of fluorescence to investigate problems at the forefront of biochemistry and cell biology. This book is not meant to be a comprehensive survey but rather to highlight areas of recent developments. It is designed to be readable to the novice and yet provide sufficient detail for the expert to keep abreast of recent developments. The book is organized so that it proceeds from simple biochemical sys tems to more complex cell biological ones. Chapter I on fluorescence quenching of biological structures is a good introductory chapter. It intro duces a number of elementary concepts and discusses applications to pro teins and biomembranes.

Book Description
Biophysical Aspects of Cerebral Circulation provides a comprehensive review of the cerebral circulatory system. This book consists of four chapters. Chapter 1 is devoted to methodology attempts to explain the special features of a biophysical approach. The biophysical principles of the most commonly used modem methods such as the clearance method and rheoencephalography are described in detail. The second and third chapters examine all the biophysical aspects of the cerebral circulatory system as a functional unit and deal with some principles of its regulation. The results of systems analysis using mathematical modeling are presented in broad outline. Chapter 4 deals with processes related to the regional cerebral circulation. Such investigations focus mainly on the relationship between periodically fluctuating factors affecting limited areas of brain tissue. This text is beneficial to medical students and individuals researching on cerebral circulation.

Book Description
The two volumes of this new edition of the Handbook cover the basic biological, medical, physical, and electrical engineering principles. They also include experimental results concerning how electric and magnetic fields affect biological systems—both as potential hazards to health and potential tools for medical treatment and scientific research. They also include material on the relationship between the science and the regulatory processes concerning human exposure to the fields. Like its predecessors, this edition is intended to be useful as a reference book but also for introducing the reader to bioelectromagnetics or some of its aspects. FEATURES • New topics include coverage of electromagnetic effects in the terahertz region, effects on plants, and explicitly applying feedback concepts to the analysis of biological electromagnetic effects • Expanded coverage of electromagnetic brain stimulation, characterization and modeling of epithelial wounds, and recent lab experiments on at all frequencies • Section on background for setting standards and precautionary principle • Discussion of recent epidemiological, laboratory, and theoretical results; including: WHO IARC syntheses of epidemiological results on both high and low frequency fields, IITRI lab study of cancer in mice exposed to cell phone-like radiation, and other RF studies • All chapters updated by internationally acknowledged experts in the field

Book Description
The book explains self-assembly and order on the basis of a biophysical mechanism using energy. Biological molecules and structures have extraordinary polar and polarization properties. Even the thermal vibrations are accompanied by polarization waves generating oscillating electric fields capable of mediation of long range interactions. In particular, the cytoskeleton is an important structure of cellular organization. On account of non-linear properties energy supplied from metabolic sources (e.g. from GTP to the microtubules and from ATP to the actin filaments) can shift the vibrations in biological systems far from thermodynamic equilibrium and excite coherent states. The generated coherent electric field can be essential for creation and maintenance of order. The book presents the hypothesis that protein phosphorylation can control the coherent vibrations whose disturbances may be connected with certain properties of malignant cells. The text of the book is accessible to biophysicists, biologists, biochemists, and to other scientists working in the interdisciplinary area between biology, chemistry, and physics.
