Download or read book Living in a Seasonal World written by Thomas Ruf and published by Springer Science & Business Media. This book was released on 2012-04-23 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarises the newest information on seasonal adaptation in animals. Topics include animal hibernation, daily torpor, thermoregulation, heat production, metabolic depression, biochemical adaptations, neurophysiology and energy balance. The contributors to this book present interdisciplinary research at multiple levels ranging from the molecular to the ecophysiological, as well as evolutionary approaches. The chapters of this book provide original data not published elsewhere, which makes it the most up-to-date, comprehensive source of information on these fields. The book’s subchapters correspond to presentations given at the 14th International Hibernation Symposium in August 2012 in Austria. This is a very successful series of symposia (held every four years since 1959) that attracts leading researchers in the field. Like the past symposia, this meeting – and consequently the book – is aimed not only at hibernation but at covering the full range of animal adaptations to seasonal environments. For the next four years, this book will serve as the cutting-edge reference work for graduate students and scientists active in this field of physiology and ecology. .

Download or read book The Diurnal Rhythm of Peripheral Heat Loss in the Rat written by Louise Oliver and published by . This book was released on 2011 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammals exhibit a robust circadian rhythm in core body temperature (Tc). The rhythm in Tc is a result of rhythms in heat production and heat loss. Heat loss is achieved mainly through the modulation of vasomotor tone, under the control of the sympathetic nervous system, and in the rat, the poorly insulated, well-vascularised tail is the principal organ of heat loss. Evidence suggests that 17[beta]-oestradiol (E2) and melatonin may modulate peripheral vasomotor tone, and thus potentially regulate diurnal rhythms in heat loss. However, there have been few previous experimental studies of the interactions between these hormones, peripheral heat loss and Tc rhythms. -- The studies described in this thesis examined the relationship between the rhythms in Tc and peripheral heat loss, measured as tail skin temperature (TST), using novel radiotelemetry devices. These devices allowed Tc and TST to be continuously and simultaneously monitored without any stressful handling. An interesting and novel finding was a clear gender difference in the diurnal rhythm of TST. This sexual dimorphism in TST was found to be E2-dependent: E2 enhanced nocturnal vasoconstriction in the tail vasculature. Investigations into the oestrogenic modulation of adrenoreceptors (ARs) in the tail artery revealed that expression of the a2c-AR was upregulated by E2 at the mRNA and protein level, indicating that the mechanisms by which E2 exerts its effects are likely to involve, at least in part, a peripheral action. Finally, the role of melatonin in regulating nocturnal peripheral heat loss was examined in vivo. Pinealectomy and melatonin replacement had no effect on nocturnal vasoactivity of the tail vasculature or diurnal rhythms in either TST or Tc, suggesting that, at least in the rat, melatonin does not regulate nocturnal peripheral heat loss or the circadian rhythm in Tc.

Download or read book Animal and Human Calorimetry written by J. A. McLean and published by Cambridge University Press. This book was released on 2007-12-03 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive survey of the theory, practice, and techniques of calorimetry as applied to the study of energy metabolism in humans and animals. Calorimetry is used to estimate nutritional requirements of man and farm livestock and to evaluate different foods. It is also a powerful tool used in research into fundamental nutritional and physiological life processes and in the evaluation of stresses imposed by abnormal or severe environments. It is currently being applied in various branches of medical research and can be used as a diagnostic tool in hospitals for investigation of metabolic disorders. The authors discuss both direct calorimetry, which measures heat loss directly, and indirect calorimetry, where heat loss is inferred by measurement of some of the chemical byproducts of metabolism. In addition, guidance is provided to the instrumentation, technical problems, and precautions necessary to obtain accurate calorimetric measurements.
Download or read book Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research written by National Research Council and published by National Academies Press. This book was released on 2003-08-22 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding on the National Research Council's Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of these animals, and guidance on adapting these guidelines to various situations without hindering the research process. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research offers a more in-depth treatment of concerns specific to these disciplines than any previous guide on animal care and use. It treats on such important subjects as: The important role that the researcher and veterinarian play in developing animal protocols. Methods for assessing and ensuring an animal's well-being. General animal-care elements as they apply to neuroscience and behavioral research, and common animal welfare challenges this research can pose. The use of professional judgment and careful interpretation of regulations and guidelines to develop performance standards ensuring animal well-being and high-quality research. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research treats the development and evaluation of animal-use protocols as a decision-making process, not just a decision. To this end, it presents the most current, in-depth information about the best practices for animal care and use, as they pertain to the intricacies of neuroscience and behavioral research.
Download or read book Rheostasis written by Nicholas Mrosovsky and published by New York : Oxford University Press. This book was released on 1990 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work offers a comprehensive re-examination and elaboration of homeostasis, a guiding principle in physiology that has received surprisingly little critical evaluation. Among the key topics addressed are questions concerning the competing demands of different regulatory systems within the body and the problem of maintaining equilibrium in such circumstances. The author makes the important point that the body does not always seek constancy of its internal environment, nor does it always react in ways that prevent change. On the contrary, sometimes physiological mechanisms actively promote change. These changes in regulated levels--termed "rheostasis"--are seen as having an adaptive value beyond a simple failure of homeostasis. This book compares and categorizes examples of rheostasis for a variety of physiological variables, and presents what is known about conflicts between different regulatory systems and their role in promoting the occurrence of rheostasis. Among other topics covered are weight loss during hibernation, calcium storage and reproduction, fever, and rates of fat deposition in adults. The work of an outstanding scholar, this integrative study represents a refreshing and essential new approach to one of the basic concepts in physiological science.
Download or read book Temperature Regulation written by A.S. Milton and published by Birkhäuser. This book was released on 2012-12-06 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many advances have been made in the field of thermoregulation in the past few years. These include our understanding of Fever, which is now considered not simply a rise in deep body temperature foHowing infection, but just one aspect, though perhaps the most easily measured, of the Acute Phase of the Immune Response. Classification and identification of the Cytokines and the availability of recombinant material has greatly aided this research. Similarly, our understanding of the Hypothalamo-Pituitary Adrenal Axis has altered our way of thinking about temperature regulation. Of importance are the problems associated with adverse climatic conditions and survival, and the problems encountered by the neonate and the hibernator. At the biochemical level, our knowledge of the control of heat production and the role of brown adipose tissue is rapidly advancing. All these issues and many others were discussed at a Symposium 'Thermal Physiology 1993' held in Aberdeen, Scotland in August 1993 under the auspices of the Thermal Physiology Commission of the International Union of Physiological Sciences. Six main aspects of the subject of temperature regulation are included in this book, namely, Fever (including the Acute Phase of the Immune Response and Thermoregulatory Peptides), Neurophysiology of Thermoregulation, Neonatal Thermoregulation, Mechanisms of Heat Production, Ecological and Behavioural Thermoregulation, and Emerging Themes in Thermoregulation.

Download or read book Recognition and Alleviation of Distress in Laboratory Animals written by National Research Council and published by National Academies Press. This book was released on 2008-04-10 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific advances in our understanding of animal physiology and behavior often require theories to be revised and standards of practice to be updated to improve laboratory animal welfare. This new book from the Institute for Laboratory Animal Research (ILAR) at the National Research Council, Recognition and Alleviation of Distress in Laboratory Animals, focuses on the stress and distress which is experienced by animals when used in laboratory research. This book aims to educate laboratory animal veterinarians; students, researchers, and investigators; animal care staff, as well as animal welfare officers on the current scientific and ethical issues associated with stress and distress in laboratory animals. It evaluates pertinent scientific literature to generate practical and pragmatic guidelines. Recognition and Alleviation of Distress in Laboratory Animals focuses specifically on the scientific understanding of the causes and the functions of stress and distress, the transformation of stress to distress, and the identification of principles for the recognition and alleviation of distress. This book discusses the role of humane endpoints in situations of distress and principles for the minimization of distress in laboratory animals. It also identifies areas in which further scientific investigation is needed to improve laboratory animal welfare in order to adhere to scientific and ethical principles that promote humane care and practice.
