Book Description
Harderian glands, first described by Jacob Harder in two species of deer in 1694, are large, intraorbital glands which, with but few exceptions, are found in all land vertebrates. Certainly, their relatively large size, their phylogenetic age, and persistent conservation in all groups as they emerged from an aqueous to an air/land environment lend strong support to the logical deduction that they probably play an important role in the physiological adaptation to terrestrial life. Yet, few biologists know even what or where these glands are. For a variety of reasons, the Harderian glands have not received the attention they deserve and, as a result, the published works available have been scarce and scattered throughout the world literature. The current situation is remarkably similar to that which existed in regard to the pineal gland prior to the mid-1960s, i. e. , scattered literature, unknown function, few investigators, and little interest. Yet, following a few key papers, interest in the pineal gland expanded and soon an explosive increase in the knowledge and understanding of the pineal gland took place and continues today. Will history repeat itself? Originally, a few of us discussed the desirability of an informal Symposium on the Harderian glands.

Book Description
The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. - With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far - Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors - Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research

Book Description
Atlas of Histology of the Juvenile Rat should be of interest to toxicologic pathologists, toxicologists, and other biological scientists who are interested in the histomorphology of juvenile rats. For several decades the laboratory rat has been used extensively in nonclinical toxicology studies designed to detect potential human toxicity of drugs, agrochemicals, industrial chemicals, and environmental hazards. These studies traditionally have involved young adult rats that are 8-10 weeks of age as studies are started. It is becoming increasingly apparent that children and young animals may have different responses to drug/chemical exposures, therefore, regulatory agencies are emphasizing toxicology studies in juvenile animals. While the histologic features of organs from young adult and aged laboratory rats are well known, less is known about the histologic features of organs from juvenile rats. Final histologic maturity of many organs is achieved postnatally, thus immature histologic features must be distinguished from chemical- or drug-related effects. While this postnatal organ development is known to exist as a general concept, detailed information regarding postnatal histologic development is not readily available. The Atlas includes organs that are typically sampled in nonclinical toxicology studies and presents the histologic features at weekly intervals, starting at birth and extending through postnatal day 42. - Written and edited by highly experienced, board-certified toxicologic pathologists - Includes more than 700 high-resolution microscopic images from organs that are typically examined in safety assessment toxicology studies - Detailed figure legends and chapter narratives present the salient features of each organ at each time interval - Figures are available for further study via Elsevier's Virtual Microscope, which allows viewing of microscopic images at higher magnification - Valuable resource for toxicologic pathologists who are confronted with interpretation of lesions in juvenile rats in situations where age-matched concurrent controls are not available for comparison, e.g., with unscheduled decedents - Figures are available for further study on ScienceDirect with Virtual Microscope, which allows viewing of microscopic images at higher magnification

Book Description
Melatonin: Biosynthesis, Physiological Effects, and Clinical Applications provides a thorough review of recent advances in major areas of melatonin research. The book is arranged in a logical sequence, beginning with the history of melatonin and then proceeding to cover its biochemistry and secretion, physiological effects, and clinical significance. New findings and current concepts are emphasized, and a significant amount of previously unpublished data are included. The book will be an important reference for neurobiologists, cell biologists, ophthalmologists, endocrinologists, neuroendocrinologists, reproductive biologists, psychiatrists, and other researchers and clinicians interested in melatonin.

Book Description
Histopathological assessment of tissue sections is an important componant of many preclinical studies which are conducted to support the safety and clinical development of novel therapeutic agents for use in the treatment of human diseases. The drug discovery process, aided by modern biotechnology, is now capable of generating highly potent, pharmacologically active agents which can give rise to quite unusual constellations of tissue pathology. The complexity and the number of histopathological findings in individual studies indicate the need for lucididy in descriptions and conclusions. In the light of these and other difficulties, this text is aimed towards bringing together into one volume a description of histopathological changes which relate to toxicity testing of therapeutic agents in the usual test species: rat, mouse, dog and non-human primate. This book is an excellent starting point for the analysis of drug-induced findings in toxicity studies.

Book Description
Research related to the pineal gland has advanced rapidly in the last three decades since the discovery of its most important hormone, melatonin. This indoleamine has been shown to have a large variety of effects in the organism; the bulk of these actions were initially thought to relate the pineal gland to the reproductive and endocrine systems. It is now apparent, however, that the physiologic interactions of the pineal and its hormones far transcend its control of endocrine function. One field of pineal research that has developed rapidly within the last 5 years has been the demonstration of its relationship to the immune system. Since the pineal gland is part of the central nervous system, these observations generally fall in the category of neuroimmunology, an area that, in its own right, has received a great deal of attention in the last decade. Thus, a NATO Advanced Study Course entitled "Role of Melatonin and Pineal Pep tides in Neuroimmunomodulation" was convened in Erice, Sicily, on June 3-9, 1990. This book is a result of the scientific presentations given at the workshop. The contributions to the book include mini-review articles which summarized the presentations of the invited speakers as well as a selected number of brief communications where the subject matter was in line with the theme of the Advanced Study Course.
