Diseases of Amphibians and Reptiles

by Gerald Hoff

While diseases of free-ranging and captive mammalian and avian wildlife species have received considerable interest in the past 25 years, those of amphibians and reptiles (collectively, the herptiles) generally have been assigned lesser importance. The literature concern­ ing disease in herptiles is widely scattered, consisting chiefly of case reports and prevalence surveys, and with heavy emphasis on captive reptiles. The dynamics of the host-agent-environment relationship have been studied for only a few diseases. This diverse data base is primarily a function of the paucity of investigators whose chief interest is in diseases of herptiles. This first edition represents an effort to bring together some of the diffuse knowledge on infectious and non-infectious diseases of free-ranging and captive herp­ tiles. Issue may be taken with the choice of topics; how­ ever, predominant diseases, as well as some diseases of lesser prominence, are presented. The editors were forced to accept certain omissions, particularly with amphibian diseases, simply for lack of contributors. The resulting text, however, we hope will be of value to veterinarians, herpetolo,gists, wildlife disease investigators, wildlife managers, zoo curators, and university students. G.L. Hoff F.L.

The American Family: Dying or Developing

by Howard Hoffman

Several years ago, an anonymous donor gave a generous gift to the Department of Psychiatry and Behavioral Sciences at George Washington University School of Medicine. The donor suggested that the gift be used to support a conference on the current dilem­ mas of the American family and to publish its proceedings. The current chairman of the department, Jerry Wiener, formulated the initial plans for the conference with Leon Yochelson, who had been chairman at the time the gift was made. Dr. Yochelson is now Chairman of the Board of the Psychiatric Institute of the District of Columbia. These initial discussions led to a significant and sus­ tained collaboration between the Department of Psychiatry and Behavioral Sciences at George Washington and the Psychiatric In­ stitute in planning the conference and the present volume. A committee was established to plan the conference. It con­ sisted of Peter Steinglass, Associate Professor of Psychiatry, and George Cohn, Professor of Child Health and Development, both of George Washington, and Margaret Garrett, a member of the psychiatric staff at the Psychiatric Institute. The committee was jointly chaired by the editors of this volume. The committee re­ ceived indispensable assistance from members of the administra­ tive staff of the Psychiatric Institute: Al Bruce, Carol Klein, and Miriam Mathura. Margaret Schnellinger of the Center for Family Research, George Washington University, was also very helpful in all phases of planning the conference.

Environmental Physiology and Biochemistry of Insects

by K. H Hoffmann

Of all the zoological classes the insects are the most numerous in species and the most varied in structure. Estimates of the number 18 of species vary from 1 to 10 million, and 10 individuals are es­ timated to be alive at any given moment. In their evolution, in­ sects are relatively ancient and, therefore, they have proved to be a phenomenally successful biological design which has survived unchanged in its basic winged form during the last 300 m. y. In­ sects were the first small animals to colonize the land with full suc­ cess. Their small size opened many more ecological niches to them and permitted a greater diversification than the vertebrates. What is it about this design that has made insects so successful in habitats stretching from arid deserts to the Arctic and Antarctic and from freshwater brooks to hot springs and salines? Is it due to the adapta­ bility of their behavior, physiology, and biochemistry to changing environmental conditions? Three features of insects are of particular importance in determin­ ing their physiological relationship with the environment: their small size, as mentioned above, the impermeability and rigidity of their exoskeleton, and their poikilothermy. Of course, as with any other animals, the insects' success in its environment depends on its ability to maintain its internal state within certain tolerable limits of temperature, osmotic pressure, pH or oxygen concentra­ tion (homoeostasis).

A Legacy for Living Systems: Gregory Bateson as Precursor to Biosemiotics (Biosemiotics #2)

by Jesper Hoffmeyer

Gregory Bateson’s contribution to 20th century thinking has appealed to scholars from a wide range of fields dealing in one way or another with aspects of communication and epistemology. A number of his insights were taken up and developed further in anthropology, psychology, evolutionary biology and communication theory. But the large, trans-disciplinary synthesis that, in his own mind, was his major contribution to science received little attention from the mainstream scientific communities. This book represents a major attempt to revise this deficiency. Scholars from ecology, biochemistry, evolutionary biology, cognitive science, anthropology and philosophy discuss how Bateson's thinking might lead to a fruitful reframing of central problems in modern science. Most important perhaps, Bateson's bioanthropology is shown to play a key role in developing the set of ideas explored in the new field of biosemiotics. The idea that organismic life is indeed basically semiotic or communicative lies at the heart of the biosemiotic approach to the study of life. The only book of its kind, this volume provides a key resource for the quickly-growing substratum of scholars in the biosciences, philosophy and medicine who are seeking an elegant new approach to exploring highly complex systems.

Oxygen Transport to Tissue XVI (Advances in Experimental Medicine and Biology #361)

by Michael C. Hogan Odile Mathieu-Costello David C. Poole Peter D. Wagner

Since its inception in 1973, The International Society on Oxygen Transport to Tissue (ISOTT) has provided a unique forum to facilitate and encourage scientific interaction and debate. Welcoming scientists and clinicians from a broad spectrum of disciplines, each with their own particular skills and expertise, ISOTT unites them under the common theme of oxygen transport. The successful blend of scientific presentations and informal discussion which characterizes ISOTT is epitomized best by the many fundamental discoveries and technical advancements which it has spawned. The breadth and strengths of The Society's scientific base promotes the rapid progression of ideas from theoretical concepts to rigorous scientific testing and often, ultimately to the clinical arena. Each publication of the ISOTT proceedings has been recognized by Science Citation Index listing and the papers frequently establish scientific precedents and become considered as standard works in their respective fields. The 21st ISOTT Meeting was held in San Diego from August 14th through August 18th, 1993. The San Diego Meeting attracted about 150 registrants and 40 accompanying persons. Ten state-of-the-art lectures were presented by international experts in ~ transport and there were in addition two symposia -one dealing with assessment of tissue hypoxia and the other with functional heterogeneity in different organ systems. There were 100 free communications, consisting of posters accompanied by an abbreviated oral summary. All manuscripts were reviewed by the Editors for form and content, but as is customary for the ISOTT proceedings, rigorous scientific peer review was not undertaken.

Stable Lass: Riding Out and Mucking In - Tales from a Yorkshire Racing Yard

by Gemma Hogg

'Poignant and compelling, an equine Bridget Jones.' Racing PostBeing a stable lass is probably one of the hardest jobs in the country, and yet for Gemma Hogg it is the most rewarding. She works in the beautiful Yorkshire market town of Middleham and if her colleagues are occasionally challenging, then the horses are downright astonishing. Now, in Stable Lass, she takes us into the closed world of a top racing yard, from the elation of having several winners in one day to the almost indescribable grief of losing a horse. Like most stable lads and lasses, Gemma arrived in her yard as a teenager fresh out of racing college and had to cope with living away from home for the first time, as well as adapting to the brutal long hours, backbreaking work and often treacherous weather. She describes falling in love with Polo Venture, the first racehorse in her care, the pure exhilaration of riding him on Middleham Gallops for the first time and what happens when a horse takes against you, from the growling gelding Valiant Warrior to the potentially lethal Broadway Boy. She brings to life the characters around the yard, from straight-talking boss Micky Hammond to the jockeys starving themselves to make weight, the wealthy owners and the other stable lads and lasses who come from a range of different places and backgrounds. Stable Lass by Gemma Hogg is a unique look into the world of horse racing filled with heart-warming stories and amazing thoroughbreds – some loveable, some cantankerous, all impressive.

by Carolin Höhlein

Carolin Höhlein untersucht vor dem Hintergrund steigender Antibiotikaresistenzen und der damit verbundenen Notwendigkeit der Reduktion der Einsatzmengen nationale veterinärmedizinische Minimierungskonzepte und prüft deren potentielle Treffsicherheit sowie auftretende Nebenwirkungen. Schwerpunkt ihrer Analyse gilt dem in Deutschland verankerten Steuerungsansatz und der 16. Novellierung des Arzneimittelgesetzes (16. AMG Novelle) im Rahmen der Deutschen Antibiotika-Resistenzstrategie (DART). Untersucht werden gleichsam die in Dänemark und den Niederlanden erlassenen Steuerungsansätze. Dabei wird deutlich, dass tiergesundheitliche Aspekte stärker als bisher bei der Entwicklung weiterer Policies mit berücksichtigt werden müssen.

Yeast Stress Responses (Topics in Current Genetics #1)

by Stefan Hohmann Willem H. Mager

Every cell has developed mechanisms to respond to changes in its environment and to adapt its growth and metabolism to unfavorable conditions. The unicellular eukaryote yeast has long proven as a particularly useful model system for the analysis of cellular stress responses, and the completion of the yeast genome sequence has only added to its powerThis volume comprehensively reviews both the basic features of the yeast genral stress response and the specific adapations to different stress types (nutrient depletion, osmotic and heat shock as well as salt and oxidative stress). It includes the latest findings in the field and discusses the implications for the analysis of stress response mechanisms in higher eukaryotes as well.

Molecular Biology and Physiology of Water and Solute Transport

by Stefan Hohmann Søren Nielsen

Biophysical studies in the 1950ies and 1960ies led to the realization that the water permeability of certain biological membranes must be due to the presence of water transporting proteins. This hypothesis was confirmed in 1991 and 1992 with the pioneering discovery of the first molecular membrane water channel, CHIP28, by Agre and coworkers. This integral membrane protein, which is abundant in the erythrocyte membrane and in many epithelial cells, is now called aquaporin-1 or AQP1. Thus the terms water channel or aquaporin are synonymous. In July 2000 more than 200 researchers came together in Gothenburg, Sweden, for the `3rd International Conference on the Molecular Biology and Physiology of Water and Solute Transport" to discuss progress in this emerging research field. 58 different presentations from this conference are the basis for this book. Cumulatively, these 58 short chapters provide a balanced overview complementing numerous recent reviews in this field.

But even when salvation finally seems within reach, they are forced to face down the ultimate question: do they want to eat a person, or become one?Feral and vulnerable, profound and playful, Henry Hoke's debut novel Open Throat is a marvel of storytelling that brings the mythic to life.

Galanin (Experientia Supplementum #102)

by Tomas Hökfelt

Galanin is a neuropeptide found both in the central and peripheral nervous system. The 29-amino acid peptide (named after its N-terminal glycine and C-terminal alanine) was identified in 1983 by its C-terminal amidation. This 'reverse' approach, that is to discover a substance through a distinct chemical feature, and only subsequently to characterize its biological activity, was novel and has been successful in the identification of several other peptides. After the structure of galanin was determined in 1983, functional studies were performed with material purified from natural sources until the synthetic form of the peptide became available. Galanin can act as transmitter, modulator and trophic factor, and is involved in a number of physiological processes such as hormone secretion, cardiovascular mechanisms, feeding and cognition. This peptide may also be of significance for a number of pathological processes/disorders including pain, depression, Alzheimer's disease, epilepsy, addiction and cancer. This wide diversity of actions is mediated by three galanin receptor subtypes. The studies reviewed in this volume give a fairly complete overview of the spectrum of the biological actions and functions of galanin and its receptors and on possible therapeutic applications in a number of pathological conditions.

Environmental Impacts of Microbial Insecticides: Need and Methods for Risk Assessment (Progress in Biological Control #1)

by Heikki M. T. Hokkanen Ann Hajek

Biological pesticides are increasingly finding therr place in IPM and increasing numbers of products are making therr way to the marketplace. Particularly in China, Latin America and Australia, implementation is proceeding on a large scale. However, in the USA and Europe, registration procedures for insect pathogens to be used for insect control have been established that requrre low levels of risk, resulting in costs of retarding the implementation of microbial agents. This book provides a review of the state of the art of studies on the envrronmental impact of microbial insecticides. It originates from a Society for Invertebrate Pathology Microbial Control Division Symposium .. Assessment of envrronmental safety of biological insecticides", organised in collaboration with the EU-ERBIC research project (FAIR5-CT97-3489). This symposium was initiated by Heikki Hokkanen and Chris Lomer, and was held at the SIP Annual Meeting in 2001 in The Netherlands. The emphasis in this book is on large scale use of microbial agents for insect control, demonstrating how this use has been proceeding with minimal envrron­ mental impact. This book is intended to be of use to regulatory authorities in determining whether further studies in eertain areas are necessary and how to conduct them if needed, or whether sufficient information has been collected already to permit fuH registration of many of these biological control agents.

In the final section the book guides you through the settling in period, discussing early training, socialisation and vet care, so your first month together can be as smooth as possible.

The Eurasian Huchen, Hucho hucho: Largest Salmon of the World (Perspectives in Vertebrate Science #5)

by J. Holcík K. Hensel J. Nieslanik L. Skácel

The need to gather available data on the Eurasien huchen - an important salmonid species - has been forced by a plain and, unfortunately, common fact of our times: the numbers and distribution of this biggest of salmonids have begun to decline and its range has begun to shrink. A seminar on the huchen - the European form of the species Hucha hucha - held in Zilina in February 1973 as a result of a suggestion of the Section for the Conservation of Fauna of the Slovak Zoological Society, indicated very clearly the sad situation. Data on the biology of the huchen are regrettably scarce despite several recent papers (Ivaska 1951, Svetina 1962, Prawochenski and Kolder 1968) with the aim of filling this gap. Supposing that without a thorough knowledge it is practically impossible to conserve any plant or animal species, the participants of the seminar concluded that the existing knowledge on the huchen should be compiled in an exhaustive monograph. The first such outline originated in 1977 under the authorship of J. Holcik, K. Hensel and L. Skacel, and was submitted as a research report to some of the central authorities. Even during the compilation of the report it became evident, however, that there is no difference between the huchen and its relative, the taimen. Consequently, we immediately began revising our first report, which took over three years.
