Download or read book Regulation of Water and Electrolytes written by Peter K.T. Pang and published by Elsevier. This book was released on 2014-02-26 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertebrate Endocrinology: Fundamentals and Biomedical Implications, Volume 2: Regulation of Water and Electrolytes provides information pertinent to vertebrate endocrine systems, which has significant contributions to basic biological and biomedical research. This book discusses the practical implications of the endocrinological studies. Organized into 13 chapters, this volume starts with an overview of the comprehensive aspects of endocrinology in mammalian and nonmammalian vertebrates, with emphasis on those systems that affect salt and water balance. This book then discusses the control of secretion as well as the function and biomedical implications of knowledge of secretion and function. Other chapters discuss several topics, including neurohypophysis, adrenal hormones, and pancreatic hormones. This text discusses as well the renin–angiotensin system. The final chapter deals with the changes that occur during vertebrate evolution in smaller peptide hormones, such as the neurohypophysial peptides and the angiotensins. Endocrinologists, biologists, graduate students, and researchers will find this book extremely useful.

Download or read book Fish Osmoregulation written by Bernardo Baldisserotto and published by CRC Press. This book was released on 2019-05-20 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish lives in environments with a wide variety of chemical characteristics (fresh, brackish and seawater, acidic, alkaline, soft and hard waters). From an osmoregulatory point of view, fish have developed several mechanisms to live in these different environments. Fish osmoregulation has always attracted considerable attention and in the last years several studies have increased our knowledge of this physiological process. In this book several specialists have analyzed and reviewed the new data published regarding fish osmoregulation. The chapters present an integrative synthesis of the different aspects of this field focusing on osmoregulation in specific environments or situations, function of osmoregulatory organs, general mechanisms and endocrine control. In addition, interactions of osmoregulatory mechanisms with the immune system, diet and metabolism were also reviewed. New emerging techniques to study osmoregulation has also been analysed.

Download or read book Biology of the Arthropod Cuticle written by A.C. Neville and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mention the words 'arthropod cuticle' to most biologists and they usually provoke a glazed expression. This is because the cuticle is commonly regarded as an inert substance. It is hoped that this book will dispel this fallacy. The study of cuticle in its proper context now involves many of the wider aspects of biology which are currently in vogue (e. g. how a hormone like ecdyson induces a specific enzyme like dopa decarboxylase; the unsolved major problem of cell gradient and polarity; the involvement of cyclic AMP in hormonal mechanisms; the extra cellular control of cuticular enzymes, of the mechanical proper ties of cuticle structural proteins, and of the orientation of fibrous molecules; and the relation of chromosome puffing to the synthesis of specific proteins). Studies on cuticle demand a variety of techniques, and examples of the following are illustrated in this book (fluorescence, phase contrast, polariza tion and Nomarski interference microscopy; infrared absorp tion; transmission and scanning electron microscopy; autora diography analyzed by electron microscopy; negative staining in the electron microscope; optical diffraction, high angle X-ray diffraction, low angle X -ray diffraction and selected area electron diffraction). I am well aware that the biophysical parts of this book are less incomplete than other aspects. A developmental biologist or a biochemist would have further elaborated other parts ofthe subject matter. Only one previous author, RICHARDS (1951)hasdevoted a book to arthropod cuticle.

Download or read book The Significance of Zoochromes written by A.E. Needham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the title indicates, the theme of this book is the functions of biochromes in animals. Recent works on zoochromes, such as those of D. L. Fox (1953), H. M. Fox and VEVERS (1960) and VUILLAUME (1969), have been concerned primarily with the chemical nature and the taxonomic distribution of these materials, and although function has been considered where relevant this has not been the centre of interest and certainly not the basis for the arrangement of the subject matter. Functional significance is a profitable focus of interest, since it is the one theme which can make biochromatology a discrete and integral subject, and because it is the main interest in all biological fields. At present chromatology seems to be a particularly schizoid subject since it is clear that in metabolic functions biochromes are acting in a chemical capacity whereas integumental pigments function mainly biophysically, in neurological and behavioural contexts. It is profitable to attempt an integration by studying the functions of as many chromes as possible, from all aspects.

Download or read book Effects of Temperature on Ectothermic Organisms written by Wolfgang Wieser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of thermoregulation in endotherms has contributed much to the emergence of the concept of control theory in biology. By the same token, the study of tempera ture adjustment in ectotherms is likely to have a far-reaching influence on ideas on the regulation of metabolism in general. The reason for this is that ectotherms, in adapting to the vagaries of a thermally unstable environment, deploy a range of subtle molecular and organismic strategies. Thus the experimenter, using temperature changes as a tool, is well equipped to analyze some of these strategies. This approach has enabled some important mechanisms of temperature-induced adaptation to be elucidated; the most striking of these are the effects on metabolism of changes in the conformation of enzymes and the transfer properties of membranes. Furthermore, there is a vague but persistent feeling among those working in this field that changes in the nervous system will ultimately prove to be the agency by which many of the molecular mechanisms of temperature adaptation are controlled. Should this indeed be the case, a new phase would soon begin in our understanding of the interactions between the systemic and the cellular levels of organization. However, it is not only questions about the causes of temperature adaptation that can provide answers of potential importance to the general biologist; of equal significance are questions as to the meaning of temperature adaptation in a particular organism.

Download or read book Osmoregulation in Birds written by E. Skadhauge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The approach of this treatise is physiological throughout. In the eyes of the author it answers the rhetorical question raised by Maurice B. Visscher at the Physiology Congress in Washington D. C. in 1968: Does physiology exist? What he meant by this question was whether the fields of cellular physiology and physiology of the various organ systems had become so large that physiology as such had vanished. The firm answer is that physiology does indeed exist. Although it is important to study physiological problems at the subcellular level, it is importan- and equally difficult - to study organ regulation at the cellular level, organ interaction, and integration into the whole organism. An account of avian osmoregulation from an integrated point of view is attempted in this book. Since reading Homer W. Smith's From Fish to Philosopher and August Krogh's Osmoregulation in Aquatic Animals verte brate osmoregulation has been in the center of the author's interest. The focus was set on avian osmoregulation after personal contact with the School of Krogh when working in the laboratory of Bodil M. Schmidt-Nielsen. The fundamental concepts and isotope techniques introduced by Hans H. Ussing have been of constant inspiration. An excellent example for the study of osmoregulation at the cellular level was given by the late Jean Maetz. The writing of this book was suggested by Donald S. Farner who is thanked for thorough editorial assistance, and especially with help in the subtle semantic peculiarities of the English language.

Download or read book Water Balance in Land Arthropods written by E. B. Edney and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writers on arthropod water relationships range from bio physicists and biochemists to population ecologists-a fact that gives cause to wonder whether the field is already too heterogeneous to be written about in a single book by a single author. I have partly avoided the problem by concentrating largely on physiological mechanisms and by omitting most aspects of behavioural regulation and most aspects of heat balance and body temperature, except when these impinge directly on water balance. Even within this limited field there has been a lot of work during the past twenty years, as a result of which some problems have been solved (or at least more clearly defined), and many others have been opened up. On the whole there has been a welcome change to a more rigorous experimental approach and it is now possible for water balance people to state their problems in physiological terms. Good progress has been made towards understanding the mechanisms involved in nearly all avenues of water uptake and loss, although problems indeed remain. The cuticle has yielded part of its secrets to electron micrography, but ex ploration by means oflipid biochemistry among other techniques is necessary for a real understanding of cuticle permeability.

Download or read book Fundamentals of Comparative Vertebrate Endocrinology written by I. Chester-Jones and published by Springer Science & Business Media. This book was released on 2013-12-14 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocrinology, as a discipline, was a late arrival in the corpus of established subjects. Its growth in recent years has been prodigious, extending from mor phology to molecular levels. Most of the major endocrine glands were noted by the early anatomists, although the adrenal glands were not described until 1563 by Bartholomaeus Eustachius (1520-1574). On the other hand, elucidation of the function of these glands was extremely slow. Key work by A. A. Berthold (1849), although overlooked at the time, showed that comb atrophy in castrated fowl was prevented by testis transplantation. The idea that glands produced substances reach ing the bloodstream directly and not via excretory ducts stemmed from Claude Bernard, who first used the term internal secretion in 1855. The clinical observa tions of Thomas Addison at Guy's Hospital-published as a monograph in 1855 entitled The Constitutional and Local Effects of Disease of the Suprarenal Capsules -were seminal. However, the stimulus of this early research did not bring imme diate widespread further investigations. Upon the discovery of secretin in 1902, Bayliss and Starling considered the term "internal secretion" to be clumsy, and the term "hormone" was coined (from OQ[!UW-1 excite or arouse) and it was first used by Starling in his Croonian of 1905.

Download or read book Autonomic Nerve Function in the Vertebrates written by S. Nilsson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intention of this book is to offer a comprehensive description and discussion of autonomic nerve function in the vertebrates from several points of view. Sections on anatomy, biochemistry of the transmitter substances and the structure, physiology and pharmacology of the different types of autonomic neurons have been included, together with chapters dealing with the autonomic nervous control of some organs and organ systems in the different vertebrate groups. Although knowledge in several of these areas is based primarily on studies of mammals, a certain emphasis has been placed on the autonomic nerve functions in the non-mammalian vertebrates to describe, from a comparative physiological point of view, the adaptations and possible "phylogenetic trends" in the development of the autonomic nerve functions in the vertebrates. It is very obvious that the literature created by the vigorous research activities within the fields of autonomic nervous anatomy, histochemistry, biochemistry, pharmacology and physiology is vast indeed, and not all aspects of the subject may have received fair treatment in the present volume. With an analogy from astronomy, it is hoped that the mass compressed into this book has reached the level of an energy-emitting neutron star, rather than the black hole which would be the result of compressing too large a mass.

Download or read book Ion Transport in Vertebrate Colon written by W. Clauss and published by Springer. This book was released on 2013-12-19 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on the colon not only serve medical interest or clinical purposes, but are also a highly interesting subject of comparative physiology, from which we can learn much about the basic principles in physiology. Presented here are examples of research on colonic ion transport of each vertebrate group, including the classical models of epithelia, rat and rabbit, and also on the special and unique features in fish, amphibians, reptiles, birds, and selected mammals such as the guinea pig. Physiology and pathophysiology of ion transport in the human large intestine are as well covered as the use of colonic cell cultures as model systems for crypt cell properties.

Download or read book The Control of Fish Migration written by R.J.F. Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish migration is important and spectacular. Migratory fish gather energy in one portion of the environment and transport it to other areas, where it often becomes available to humans or to other elements in the ecosystem. Migration brings fish into situations that allow easy harvest as they concentrate along migration routes. Their journeys also make them vulnerable to human intereference at critical points along their route. Salmon, for example, may harvest plankton in the open ocean and transport that food energy to coastal and inland regions, where it is captured by fisheries or deposited in inland streams and utilized by the flora and fauna of the region. These salmon are able to complete journeys of thousands of kilometers from their natal streams to oceanic feeding grounds and back to the same home streams, an accomplishment that strains our credi bili ty . We now understand some of the timing and guiding stimuli used in these migrations, and mechanisms can be logically proposed, on the basis of the established abilities of fishes, to account for the unexplained portions of the migrations. There is no single factor guiding these fish. Instead, they are dependent on the presence in their environment of a great variety of appropriate orienting and timing stimuli. These stimuli are vulnerable to human interference. The more widespread and easily available the information on these requirements, the more readily fish can be protected from such interference.
