This book deals with the mechanism of signal transduction in vertebrate and invertebrate photoreceptors. It contains contributions on the structure and function of rhodopsin or other G-coupled receptors, on the regulation of second messengers by enzyme cascade, the role of Ca2+ in light adaptation, control of ionic channels in photoreceptor cells.
Significant progress has been made in the research into the molecular basis of vision, especially retinal proteins, which are the components of visual reception. The results of these studies open wide prospects for their application in medicine and in the construction of unique light-sensitive materials for holography and microelectronics. Therefore, research into retinal proteins is not only important for understanding the mechanisms of the native light-transducing systems but also for the development of new technologies. An international group of scientists discussed the key aspects of the study of light-sensitive systems at the Conference on Retinal Proteins held in July 1986. This Proceedings volume contains 45 papers that were presented on this important topic in molecular biology.
John Lythgoe was one of the pioneers of the 'Ecology of Vision', a subject that he ably delineated in his classic and inspirational book published some 20 years ago [1]. At heart, the original book aimed generally to identify inter-relationships between vision, animal behaviour and the environment. John Lythgoe excelled at identifying the interesting 'questions' in the ecology of an animal that fitted the 'answers' presented by an analysis of the visual system. Over the last twenty years, however, since Lythgoe's landmark publication, much progress has been made and the field has broadened considerably. In particular, our understanding of the 'adaptive mechanisms' underlying the ecology of v...
The penultimate novel in the Strangers and Brothers series takes Goya’s theme of monsters that appear in our sleep. The sleep of reason here is embodied in the ghastly murders of children that involve torture and sadism.
Presents the current state of the art in lightning science, for advanced undergraduate and graduate students on a single-semester course.
Covering key terms and concepts in the emerging field of posthumanism and literacy education, this volume investigates posthumanism, not as a lofty theory, but as a materialized way of knowing/becoming/doing the world. The contributors explore the ways that posthumanism helps educators better understand how students, families, and communities come to know/become/do literacies with other humans and nonhumans. Illustrative examples show how posthumanist theories are put to work in and out of school spaces as pedagogies and methodologies in literacy education. With contributions from a range of scholars, from emerging to established, and from both U.S. and international settings, the volume cov...
The cloning, sequencing, and expression of a variety of membrane receptors and channels indicate the existence of at least four "superfamilies" of molecular structures that mediate signal transduction. Presently, more than 400 receptors have been cloned and sequenced. The Handbook of Receptors and Channels is the first handbook series to present the enormous amount of new molecular biological receptor data in a practical and useful format. Each volume in this remarkable series will focus on a specific molecular superfamily of receptors. Complete amino acid sequence information on all cloned receptors, as well as relevant pharmacological information, will be included. Furthermore, the format for each of the volumes will be consistent to allow for easy comparisons of different molecular subtypes for a given transmitter. G Protein-Coupled Receptors is the first volume in this new handbook series. Topics covered in future volumes include:
