Download or read book Amphibian Metamorphosis written by Yun-Bo Shi and published by Wiley-Liss. This book was released on 1999-10-18 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an age when advanced molecular and genetic tools allow studies in various systems, amphibian metamorphosis still offers perhaps the most accessible model for the study of postembryonic organogenesis and mechanisms of hormonal regulation during vertebrate development. Amphibian Metamorphosis: From Morphology to Molecular Biology integrates findings from the most recent research with earlier observations, providing molecular and mechanistic insights into the signal transduction pathways underlying tissue-specific transformations during metamorphosis. The author, renowned expert of anuran metamorphosis and Head of the Unit of Molecular Morphogenesis at NICHD/NIH, begins with an overview of metamorphosis in different classes of amphibians and various factors that influence this process. A review of earlier morphological, cellular, and biochemical changes focuses on organs and tissues that have been studied extensively at the molecular level, while discussion of the thyroid hormone signal transduction pathway emphasizes transcriptional regulation mechanisms by thyroid receptors. The book provides a summary and comparison of gene regulation programs induced by thyroid hormone in several organs that undergo distinct metamorphic transformations. Several chapters are devoted to functional and mechanistic implications of the molecular findings on the thyroid hormone response genes in tissue transformation. Special features of this book include: * An emphasis on integrating the morphological approach with molecularand cell biology * A historical perspective on the progression from discovery of the thyroid hormone to present-day research advances * Comparisons of amphibian and insect metamorphosis * Dozens of instructive photographs, several in full color Amphibian Metamorphosis: From Morphology to Molecular Biology is a unique and invaluable resource for professionals and aspiring professionals in develop-mental biology, molecular biology, cell biology, evolutionary biology, and endocrinology.
Download or read book Mechanisms of Life History Evolution written by Thomas Flatt and published by OUP Oxford. This book was released on 2011-05-12 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).

This book was released on 2009-07-24 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355–359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates.

Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.

This book was released on 2012-12-06 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.
Download or read book Thyroid Disease and Reproduction written by Jennifer L. Eaton and published by Springer. This book was released on 2018-10-31 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a practical, evidence-based resource covering thyroid disease and its effects on reproduction and fertility, discussing thyroid function and dysfunction - hypothyroidism and hyperthyroidism, thyroid nodules and cancer - during pregnancy as well as its effects on the fetus. It begins with a review of the anatomy and function of the thyroid and the biosynthesis and physiology of thyroid hormones, as well as the pathophysiology of thyroid dysfunction. The chapters that follow discuss thyroid function and dysfunction (e.g., hypothyroidism and hyperthyroidism) during pregnancy and its effects on fertility as well as the developing fetus. The management of thyroid nodules and cancer, the role of thyroid dysfunction in infertility, the role of thyroid autoimmunity and miscarriage, and postpartum thyroiditis are presented in detail in the concluding chapters. Clinical cases and outcomes bookend each chapter, demonstrating current management strategies for a well-rounded presentation. Filling a clear gap in the literature usually covered only briefly in larger texts on the thyroid, Thyroid Disease and Reproduction: A Clinical Guide to Diagnosis and Management is a unique resource for reproductive endocrinologists, obstetrician/gynecologists, and residents and students in these clinical areas.
Download or read book Development of Auditory and Vestibular Systems written by Raymond Romand and published by Academic Press. This book was released on 2014-05-23 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of Auditory and Vestibular Systems fourth edition presents a global and synthetic view of the main aspects of the development of the stato-acoustic system. Unique to this volume is the joint discussion of two sensory systems that, although close at the embryological stage, present divergences during development and later reveal conspicuous functional differences at the adult stage. This work covers the development of auditory receptors up to the central auditory system from several animal models, including humans. Coverage of the vestibular system, spanning amphibians to effects of altered gravity during development in different species, offers examples of the diversity and complexity of life at all levels, from genes through anatomical form and function to, ultimately, behavior. The new edition of Development of Auditory and Vestibular Systems will continue to be an indispensable resource for beginning scientists in this area and experienced researchers alike. Full-color figures illustrate the development of the stato-acoustic system pathway Covers a broad range of species, from drosophila to humans, demonstrating the diversity of morphological development despite similarities in molecular processes involved at the cellular level Discusses a variety of approaches, from genetic-molecular biology to psychophysics, enabling the investigation of ontogenesis and functional development

Download or read book Modulation of Synaptic Transmission and Plasticity in Nervous Systems written by Georg Hertting and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on a workshop "Modulation of Synaptic Transmission and Plasticity in Nervous Systems" held in n Ciocco, Castelvecchio, Pascoli, Italy, from September 8th to 13th, 1987. The purpose of the meeting was to bring together scientists working on plasticity in nervous systems on different levels. The contributions can be subgrouped into six fields of research: 1) Presynaptic Modulation of Chemical Neurotransmission 2) Postsynaptic Signal Transduction 3) Modulation of Synaptic Transmission and Plasticity in the Hippocampus 4) Modulation of Neuromuscular Transmission 5) Molecular and Cellular Analysis of Conditioning in Marine Snails 6) Analysis of Learning and Memory in Insects Understanding how nervous systems and in particular our brain processes and stores information has been a major challenge in science for centuries and will remain for some time to come. Not until recently neurobiologists agreed to seek plasticity of behavior primarily in the modulation of the properties of synapses between nerve cells. This is to be understood within the context provided by a neural circuitry. An important stimulus came from the work on the marine snail Aplysia, where learning processes can be described as a modulation of transmitter release, traced back to a complete chain of molecular events in an identified neuron. Learning became a topic of molecular biology. Three systems appear particularly promising for this approach: insects, in particular Drosophila, marine snails and the mammalian hippocampal tissue. Our views on neurotransmission have rapidly changed.
