Biochemical Oscillations And Cellular Rhythms

This book addresses the molecular bases of some of the most important biochemical rhythms known at the cellular level. Clarifying the mechanism of these oscillatory phenomena is of key importance for understanding the origin as well as the physiological function of these rhythms, and the conditions in which simple periodic behaviour transforms into complex oscillations, including bursting and chaos. The approach rests on the analysis of theoretical models closely related to experimental observations. Among the main rhythms considered are glycolytic oscillations observed in yeast and muscle, oscillations of cyclic AMP in Dictyostelium amoebae, intracellular calcium oscillations observed in a variety of cell types, the mitotic oscillator that drives the cell division cycle in eukaryotes, and circadian oscillations of the period protein (PER) in Drosophila. For each of these phenomena, experimental facts are reviewed and mathematical models presented.

Among the main rhythms considered are glycolytic oscillations observed in yeast and muscle, oscillations of cyclic AMP in Dictyostelium amoebae, intracellular calcium oscillation observed in a variety of cell types, the mitotic oscillator that drives the cell division cycle in eukaryotes, pulsatile hormone signaling, and circadian rhythms in Drosophila. This book will be of interest to life scientists such as biochemists, cell biologists, chronobiologists, medical scientists and pharmacologists. In addition, it will appeal to scientists studying nonlinear phenomena, including oscillations and chaos, in chemistry, physics, mathematics and theoretical biology.

Biological and Biochemical Oscillators compiles papers on biochemical and biological oscillators from a theoretical and experimental standpoint. This book discusses the oscillatory behavior, excitability, and propagation phenomena on membranes and membrane-like interfaces; two-dimensional analysis of chemical oscillators; and chemiluminescence in oscillatory oxidation reactions catalyzed. The problems associated with the computer simulation of oscillating systems; mechanism of single-frequency glycolytic oscillations; excitation wave propagation during heart fibrillation; and biochemical cycle of excitation are also elaborated. This compilation likewise covers the physiological rhythms in Saccharomyces cerevisiae populations; integral and indissociable property of eukaryotic gene-action systems; and role of actidione in the temperature jump response of the circadian rhythm in Euglena gracilis. This publication is valuable to biochemists interested in biochemical and biological oscillations.

The Biological Clock describes the rhythmic processes in a great variety of plants and animals. This book is an outgrowth of the 1969 James Arthur Lecture Series on "Time and its Mysteries" held at New York University. This three-chapter work begins with the basic principles of biological rhythms and clocks, along with various diagrams to illustrate some aspects of circadian rhythms in animals. The second chapter discusses the hypothesis of environmental timing of the clock. This chapter explores numerous research studies on phenomenon of biological rhythms, the nature of the rhythmic mechanism, and hormonal regulation. The third chapter examines the cellular-biochemical clock hypothesis and its contribution in the progress of understanding the complexity of biological rhythm. This book is intended primarily for biologists, behaviorists, and researchers.

An intriguing class of biological periodicity consists of rhythms with about 24-hour periods occurring at every level of eukaryotic organization. Progress is being made in understanding these rhythms. The six chapters of this work include a brief introduction to circadian (24-hour) rhythms, a survey of circadian organization at the cellular level, and a description of the important microorganisms that have served as experimental models for biochemical analysis. Also considered are relations between cell division cycles and circadian oscillators, as well as some general and theoretical aspects. Where appropriate, parallels are drawn to neuronal oscillators. This volume will introduce and critically appraise modern chronobiology; its extensive illustrations and comprehensive up-to-date bibliography will make it an authoritative reference.

During the past decade many review papers and books have been devoted to descriptions and analyses of biological rhythms (chronobiology) in plants and animals. These contributed greatly to demonstrating the impor tance of bioperiodicities in living beings in general. However, the practi cal aspects of chronobiology with regard to human health and improving the treatment of disease have not yet been a major focus of publication. One of our aims is to establish the relevance of biological rhythms to the practice of medicine. Another is to organize and convey in a simple fashion information pertinent to health- and life-science professionals so that students, researchers, and practitioners can achieve a clear and pre cise understanding of chronobiology. We have limited scientific jargon to unavoidable basic and well-defined terms and we have emphasized illus trative examples of facts and concepts rather than theories or hypotheti cal mechanisms. This volume is divided into seven chapters, each of which is compre hensive in its treatment and includes an extensive bibliography. The book is organized to serve as a textbook and/or reference handbook of modem applied chronobiology. Chapter 1 describes the historical development of chronobiology and reviews why, when, and how major concepts were introduced, accepted, and transformed.

Biological Oscillators: Their Mathematical Analysis introduces the main features of the dynamic properties of biological oscillators and the mathematical techniques necessary for their investigation. It is not a comprehensive description of all known biological oscillators, since this would require a much bigger volume as well as a different type of expertise. Instead certain classes of biological oscillators are described, and then only in as much detail as required for the study of their dynamics. The opening chapter reviews fundamental mathematical concepts and techniques which will be used in the remainder of the book. These include phase plane techniques; asymptotic techniques of Krylov, Bogoliubov, and Mitopolski; and the describing function. Subsequent chapters discuss examples of biological oscillators; phase shifts and phase response curves; the entrainment of oscillators by external inputs; the dynamics of circadian oscillators; effects of changing environment on the dynamics of biological oscillators; the features peculiar to populations of interacting oscillators; and biological phenomena attributable to populations of oscillators.

​This book provides an overview of circadian rhythms and cellular networks in their relation to biological systems and dynamical medicine. Six concise chapters explore circadian cell rhythms and biomarkers in inflammation, cardiovascular disease, cancer, depression, and more in causing and treating these ailments. The final chapter discusses optimization of drug delivery and individualized treatment systems using chronotherapy and chronobiology-based biomarkers as a general system of medicine. Succinct yet comprehensive, Cellular Rhythms and Networks, part of SpringerBriefs in Cell Biology presents a novel framework for clinical applications in personalized and systems medicine. It is invaluable reading for researchers and clinicians in cell biology, mood disorders, and systems medicine.
