Book Description
The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.

Book Description
Principles of Regeneration focuses on the principles, methodologies, and changes involved in the process of regeneration. The book first underscores the nature of the nucleus in Acetabularia, enzyme effects, role of ribonucleic acid in morphogenesis, and functions of the stentor. The text then takes a look at the turnover in hydroids and flatworms and regeneration blastema. Discussions focus on regeneration in hydra, interstitial cells, colonial hydroids, neoblasts, and morphogenetic fields. The publication surveys segmental addition in annelids and molting, metamorphosis, and regeneration in arthropods. The termination of regeneration, importance of nerves, morphogenesis, histogenesis of the regenerate, and role of the nerves are discussed. The manuscript also examines regeneration in fishes, amphibian limb, horns and antlers, and heads and tails. The manuscript is a dependable source of data for students of developmental biology, anatomy, and evolution, as well as teachers and researchers in biology and medicine.

Book Description
This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.

Book Description
“A beautifully written journey into the mechanics of the world of the cell, and even beyond, exploring the analogy with computers in a surprising way” (Denis Noble, author of Dance to the Tune of Life). How does a single-cell creature, such as an amoeba, lead such a sophisticated life? How does it hunt living prey, respond to lights, sounds, and smells, and display complex sequences of movements without the benefit of a nervous system? This book offers a startling and original answer. In clear, jargon-free language, Dennis Bray taps the findings from the discipline of systems biology to show that the internal chemistry of living cells is a form of computation. Cells are built out of molecular circuits that perform logical operations, as electronic devices do, but with unique properties. Bray argues that the computational juice of cells provides the basis for all distinctive properties of living systems: it allows organisms to embody in their internal structure an image of the world, and this accounts for their adaptability, responsiveness, and intelligence. In Wetware, Bray offers imaginative, wide-ranging, and perceptive critiques of robotics and complexity theory, as well as many entertaining and telling anecdotes. For the general reader, the practicing scientist, and all others with an interest in the nature of life, this book is an exciting portal to some of biology’s latest discoveries and ideas. “Drawing on the similarities between Pac-Man and an amoeba and efforts to model the human brain, this absorbing read shows that biologists and engineers have a lot to learn from working together.” —Discover magazine “Wetware will get the reader thinking.” —Science magazine

Book Description
The Biology of Cilia and Flagella reviews advances in the study of cilia and flagella since 1928. This book focuses on four main topics—structure of cilia, factors that affect ciliary activity, movement of cilia and flagella, and coordination of beat of cilia. In these topics, this compilation specifically discusses the intracellular structures associated with ciliary bases; viscosity of the medium and ciliary activity, and energy relationships of cilia and flagella. The compounding of synchronously beating cilia, variations in shaft structure, and control of ciliary activity by the organism are also elaborated. This text likewise covers the determination of the rate of beat of cilia and root-fiber systems and coordination of ciliary beat. This publication is suitable for biologists and clinicians of other disciplines researching on the structure and physiology of cilia and flagella.

Book Description
This book collects the publications of Shinya lnou(r), pioneering cell biophysicist and winner of the 2003 International Prize for Biology. The articles cover the discovery, and elucidate the behavior in living cells, of the dynamic molecular filaments which organize the cell and play a central role in cell division. Other articles report on the development of microscopes, especially those using polarized light and digital image enhancement, which make possible studies of the ever-changing molecular architecture directly in living cells. This book also contains many high quality photo-micrographs as well as an appended DVD with an extensive collection of video movies of active living cells. After training in Tokyo and at Princeton University, Dr Inou(r) has held teaching positions at the University of Washington, Tokyo Metropolitan University, University of Rochester, Dartmouth Medical School, and University of Pennsylvania. He is a member of the U.S. National Academy of Sciences and currently holds the title of Distinguished Scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts."

Book Description
The goals of the science of photobiology can be divided into four categories: to develop (I) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and physicists; because photobiology is a truly multidisciplinary science. While a multidis ciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for theoretical or practical use. Photochemical and Photobiological Reviews continues to provide in depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger scientists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate. Since it is important that this review series remain responsive to the needs of photochemists and photobiologists, the Editor would value com ments and suggestions from its readers.
