This book was released on 2013-03-09 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: I see a man's life is a tedious one. Cymbeline, Act III, Sc. 6. It is well known that the best way to learn a subject is to teach it! Along the same lines one might also say that a pleasant way of learning a subject and at the same time getting to know quite a few of the workers active in it, is to arrange and to attend an Advanced Study Institute (ASI) or a workshop lasting about two weeks. This was and is the wisdom behind the NA TO-ASI programme and much as people fear that a fortnight may be too long, before it is over everyone feels that it was too short, especially if the weather had cooperated. Organising this ASI which resulted in this volume has been a very good learning experience. I started my career in research with invertebrates and retained an interest in them over the years due to my teaching a course and working sporadically on various aspects of photoreception in Polychaetes, Crustaceans and Insects. Thus, the thought of organising an ASI on photoreception and vision in invertebrates had been brewing in my mind for the past half a dozen years or so. It was felt that it will be desirable to do a bit of stock taking and discuss possible new approaches to the study of this matter.
Book Synopsis Photoreceptors and Light Signalling by : Alfred Batschauer
Download or read book Photoreceptors and Light Signalling written by Alfred Batschauer and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive coverage of the most important areas in photoreceptors and light signalling. Photoreceptors enable most species to sense not only the presence of light but also the information, such as irradiance, colour or spectral distribution, direction and polarization of light. They are vital, therefore, in providing organisms with energy and information about their surroundings, such as day and night cycles. This book covers the range of photoreceptors that have been discovered to date and the broad range of methods used when researching how they operate, including: action spectroscopy; methods for protein purification; the whole range of molecular biological and genetic methods; and numerous spectroscopic methods, from absorption and fluorescence spectroscopy to X-ray diffraction, used for solving the structure of photoreceptors. Written by leading experts in the field, Photoreceptors and Light Signalling provides the reader with the most recent results and research. This book will be valued by a wide-range of readers, including students of photochemistry, photobiology, biology, chemistry and physics and other professionals in academia.
Book Synopsis Vertebrate Photoreceptors by : Takahisa Furukawa
Download or read book Vertebrate Photoreceptors written by Takahisa Furukawa and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a series of comprehensive views on various important aspects of vertebrate photoreceptors. The vertebrate retina is a tissue that provides unique experimental advantages to neuroscientists. Photoreceptor neurons are abundant in this tissue and they are readily identifiable and easily isolated. These features make them an outstanding model for studying neuronal mechanisms of signal transduction, adaptation, synaptic transmission, development, differentiation, diseases and regeneration. Thanks to recent advances in genetic analysis, it also is possible to link biochemical and physiological investigations to understand the molecular mechanisms of vertebrate photoreceptors within a functioning retina in a living animal. Photoreceptors are the most deeply studied sensory receptor cells, but readers will find that many important questions remain. We still do not know how photoreceptors, visual pigments and their signaling pathways evolved, how they were generated and how they are maintained. This book will make clear what is known and what is not known. The chapters are selected from fields of studies that have contributed to a broad understanding of the birth, development, structure, function and death of photoreceptor neurons. The underlying common word in all of the chapters that is used to describe these mechanisms is “molecule”. Only with this word can we understand how these highly specific neurons function and survive. It is challenging for even the foremost researchers to cover all aspects of the subject. Understanding photoreceptors from several different points of view that share a molecular perspective will provide readers with a useful interdisciplinary perspective.
Book Synopsis Photoreceptors by : Antonio Borsellino
Download or read book Photoreceptors written by Antonio Borsellino and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume or1g1nates from a NATO Advanced Study Institute on "Photoreceptors" dedicated to M.G.F. Fuortes, held in Erice 1-12 July 1981. The lectures given at the course provided a general review of the photoreceptors functions in both vertebrate and inver tebrate eyes. Elaborating on the most recent hypotheses the lec tures also added new and interesting details. In order to preserve the novelty and freshness of the subject matter and thus ensure the usefulness of the volume, the authors in their written contributions emphasize more specific findings of their current research rather than the tutorial nature of the lectures actually presented. The contributors of this volume wish to dedicate their papers to the memory of Mike Fuortes, who has been for many of them an inspiring collegue and friend. Five papers that do not strictly pertain to the topics of the course are also included in the volume, the authors could not attend the meeting, but wanted to contribute an article to this memorial volume.
Download or read book Photoreceptors written by Alan Fein and published by CUP Archive. This book was released on 1982-08-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanism by which photoreceptor cells in the eyes of higher animals absorb light, giving rise to receptor potentials that initiate the visual process, is a subject of active research in biophysics today. The pace of this research and its multidisciplinary nature have made it difficult for the nonexpert to keep abreast of new discoveries. This book aims to provide a more coherent, compact summary of our knowledge about the field that has been available, serving as an up-to-date introduction to the role of photoreceptors in vision. The book is a self-contained, concise handbook for the reader who has at least a college level knowledge if cell biology, biochemistry, physical chemistry, neurobiology and physics. The authors describe the physical parameters of light and proceed to describe the mechanisms by which photoreceptors extract information about each parameter. The discussion of mechanisms is organized by discipline, following the general sequence of cellular morphology, visual pigment chemistery, and receptor physiology. Photoreceptors: their role in vision is an integrated sourcebook which will serve the novice as a 'stepping stone' to the vast and exciting scientific literature of the field.
Book Synopsis Neurobiology of Invertebrates by : J. Salanki
Download or read book Neurobiology of Invertebrates written by J. Salanki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 1967 a Symposium on Neurobiology of Invertebrates was held at Tihany, in the Biological Research Institute of the Hungarian Academy of Sci ences, coinciding with the 40 years anniversary of this Institute. Its Department of Experimental Zoology, representing the most important basis for researches in Hungary on the nervous system of invertebrates, organized the meeting. The Symposium covered both morphological and functional aspects of inver tebrate neurobiology from the viewpoints of elementary processes as well of regu latory mechanisms. The complex approach of identic or similar problems is a generally accepted trend in biological research - this tendency is well reflected in the 34 papers presented by participants of the Symposium coming from different countries of Europe and the United States. The volume contains all but one of the lectures held at the meeting; the paper of A. K. Voskresenskaya included in the Proceedings could not be read because of the tragic death of the author, some weeks before the Symposium. The volume is separated into 4 parts according to the 4 days program, however this division is rather tentative because of over lappings in the different fields. Discussion following the lectures are also pub lished in short, however it was impossible to give a full picture in this respect. The Biological Department of the Hungarian Academy of Sciences deserves special gratitude for the financial support of the Symposium.
Book Synopsis Bioelectrochemistry of Cells and Tissues by : Dieter Walz
Download or read book Bioelectrochemistry of Cells and Tissues written by Dieter Walz and published by Birkhäuser. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. The role of electric and magnetic fields in biological systems forms the focus of this second volume in the Bioelectrochemistry series. The most prominent use of electric fields is found in some fish. These species generate fields of different strengths and patterns serving either as weapons, or for the purpose of location and communication. Electrical phenomena involved in signal transduction are discussed by means of two examples, namely excitation-contraction coupling in muscles and light transduction in photoreceptors. Also examined is the role of electrical potential differences in energy metabolism and its control. Temporal and spatial changes of the potential difference across the membranes of nerve cells are carefully evaluated, since they are the basis of the spreading and processing of information in the nervous system. The dielectric properties of cells and their responses to electric fields, such as electrophoresis and electrorotation, are dealt with in detail. Finally, the effects of magnetic fields on living systems and of low-frequency electromagnetic fields on cell metabolism are also considered. Further volumes will be added to the series, which is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.
Book Synopsis Photoprocesses, Photoreceptors, and Evolution by : Jerome J. Wolken
Download or read book Photoprocesses, Photoreceptors, and Evolution written by Jerome J. Wolken and published by Academic Press. This book was released on 2013-10-22 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoprocesses, Photoreceptors, and Evolution discusses the important role that visible radiation has played in the development of photoreceptor systems, hence, in the evolution of life on earth. The book examines the spectrum of energies that impinge on the Earth, what kinds of molecules absorb these energies, and how they are structured within the cell to function as a photoreceptor system. The text describes the molecular structure of the cell membrane; the various kinds of pigment molecules; and the structures associated with photobiological phenomena. The relationship between the photoreceptor system and behavior, i.e. phototropism and phototaxis, photosynthesis, and vision, is also considered. The book further tackles the photoprocesses which function in photoperiodic phenomena - the "biological clocks, aging, memory, and bioluminescence. The text then demonstrates the structure of the invertebrate and vertebrate photoreceptors; and the intervebrate and vertebrate visual pigments and their photochemistry. Photobiologists will find the book invaluable.

Book Synopsis Transduction in Biological Systems by : Cecilia Hidalgo
Download or read book Transduction in Biological Systems written by Cecilia Hidalgo and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume originated from the workshop "Transduction in Biological Sys tems," held at the Marine Biological Station of the Universidad de Valparaiso, Mon temar, Chile, May 23-30, 1988, and contains contributions from most of the partici pants in the workshop. The title of both the workshop and the book reflects accurately the central theme discussed during several days of intense debate and profound intellectual exchange in the peaceful environment offered by the central coast of Chile. It was apparent that the workshop was a great success-a sentiment expressed by many seasoned attendees, some of whom dared opinions as strong as "It was the best ever." There is no single reason to explain why this workshop was so successful. Certainly instrumental was the incredible effort displayed by the Chilean Organizing Committee in selecting adequate facilities and in organizing social events that supplemented the scien tific sessions and provided an authentic fraternal environment for the participants. Equally important were the foreign participants, who enthusiastically gave of their time to take part in the event, and the students, who came from Chile as well as from several other Latin American countries, and who applied the necessary pressure in their repeated demands for scientific clarity, accuracy, and sincerity.

Book Synopsis The Science of Photobiology by : Kendric C. Smith
Download or read book The Science of Photobiology written by Kendric C. Smith and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of The Science of Photobiology was published in 1977, and was the first textbook to cover all of the major areas of photobiology. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. In this edition, however, the topics of phototechnology and spectroscopy have been com bined in a new chapter entitled "Photophysics." The other subspecialty areas remain the same, i.e., Photochemistry, Photosensitization, UV Radiation Effects, Environmental Photobiology, Photomedicine, Circadian Rhythms, Extraretinal Photoreception, Vision, Photomorphogenesis, Photomovement, Photosynthesis, and Bioluminescence. This book has been written as a textbook to introduce the science of photobiology to advanced undergraduate and graduate students. The chapters are written to provide a broad overview of each topic. They are designed to contain the amount of information that might be presented in a one-to two-hour general lecture. The references are not meant to be exhaustive, but key references are included to give students an entry into the literature. Frequently a more recent reference that reviews the literature will be cited rather than the first paper by the author making the original discovery. The chapters are not meant to be a repository of facts for research workers in the field, but rather are concerned with demon strating the importance of each specialty area of photobiology, and documenting its relevance to current and/or future problems of man.
Book Synopsis Eckert Animal Physiology by : David J. Randall
Download or read book Eckert Animal Physiology written by David J. Randall and published by Macmillan. This book was released on 2002 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic animal physiology text focuses on comparative examples that illustrate the general principles of physiology at all levels of organisation—from molecular mechanisms to regulated physiological systems to whole organisms in their environment. This textbook is an authoritative and complete guide to the field of animal physiology which uses a threefold approach to teaching. The Comparative Approach emphasises basic mechanisms but allows patterns of physiological function in different species to demonstrate how evolution creates diversity. This approach encourages students to appreciate the underlying principles that govern physiological systems. The Experimental Emphasis helps students to understand the process of scientific discovery and shows how our knowledge of physiology continually increases and finally the Integrative Approach presents information about specific physiological systems at all levels of organisation, from molecular interactions to interactions between an organism and its environment.n included.
