Book Description
This book provides a comprehensive and up-to-date account of the information available on the morphological, physiological and evolutionary aspects of specialized cells distributed within the epithelia of the airways in the vertebrates. A lot of work has been done on the cell and molecular biology of these cells which are regarded as as oxygen receptor neuroepithelial cells. These chemoreceptors which were conserved throughout evolution have neuroendocrine functions carrying their signals to the central nervous system. The chemoreceptor cells are sensors which detect the signal changes in the external and internal environments, and play a key role in the survival of various species. Studies addressed to the chemoreceptor cell systems in the airways are of great importance for investigating their response to changes in the oxygen and carbon dioxide concentrations in the environment since the future of the planet earth is being threatened by global warming and climate change. Praise for the book: ...This volume would be of special interest to researchers who are curious about the evolution of vertebrate respiratory control in general and the regulation of ventilation in nonmammalian vertebrates in particular. -Wayne L. Silver, Wake Forest University, in The Quarterly Review of Biology, Volume 85, Number 2

Book Description
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.

Book Description
Edited and authored by a wealth of international experts in neuroscience and related disciplines, this key new resource aims to offer medical students and graduate researchers around the world a comprehensive introduction and overview of modern neuroscience. Neuroscience research is certain to prove a vital element in combating mental illness in its various incarnations, a strategic battleground in the future of medicine, as the prevalence of mental disorders is becoming better understood each year. Hundreds of millions of people worldwide are affected by mental, behavioral, neurological and substance use disorders. The World Health Organization estimated in 2002 that 154 million people globally suffer from depression and 25 million people from schizophrenia; 91 million people are affected by alcohol use disorders and 15 million by drug use disorders. A more recent WHO report shows that 50 million people suffer from epilepsy and 24 million from Alzheimer’s and other dementias. Because neuroscience takes the etiology of disease—the complex interplay between biological, psychological, and sociocultural factors—as its object of inquiry, it is increasingly valuable in understanding an array of medical conditions. A recent report by the United States’ Surgeon General cites several such diseases: schizophrenia, bipolar disorder, early-onset depression, autism, attention deficit/ hyperactivity disorder, anorexia nervosa, and panic disorder, among many others. Not only is this volume a boon to those wishing to understand the future of neuroscience, it also aims to encourage the initiation of neuroscience programs in developing countries, featuring as it does an appendix full of advice on how to develop such programs. With broad coverage of both basic science and clinical issues, comprising around 150 chapters from a diversity of international authors and including complementary video components, Neuroscience in the 21st Century in its second edition serves as a comprehensive resource to students and researchers alike.

Book Description
Within the world of medicine, the work the pathologist does is integral to positive patient outcomes, but it is rare for the pathologist to actually have any interaction with their patients. Thus, their work can often go unrecognized and uncelebrated. The Unsung Heroes of Paediatric Medicine paints a broad portrait of the myriad facets that go into the making of a superb department of paediatric pathology. Not only is it the science, but it is also the people that helped to make a department such as this grow and flourish, becoming one of the best, if not the best, in North America. Within these pages, Dr. Cutz walks the reader through a century of pediatric pathology at Sick Kids Hospital in Toronto, Ontario. Building on both personal experience and archival material, Dr. Cutz’s memoir touches on the history of pathology and the evolution of pediatric pathology, then moves into a detailed overview of both the leadership and staff of the Department of Pathology at Sick Kids Hospital. In addition, readers can follow Dr. Cutz’s personal journey from his research fellowship to his beginnings as a staff pathologist, ending with his research advances and breakthroughs all made whilst a pathologist at Sick kids. Unsung Heroes also touches on controversies, tragedies, and challenging events from the hospital's history, including digoxin, the Olivieri affair, the rise and fall of Charles Smith, and the Mother Risk controversy, among others.

Book Description
This monograph sheds new light on pulmonary sensory receptors. Diving into the pulmonary microenvironment, the book focuses on the role of pulmonary neuroepithelial bodies (NEBs) as potential receptors and effectors, able to store and release neurotransmitters. It explores NEBs as potential stem cell niche and highlights the multidisciplinary approach taken to identify and study NEBs, including functional morphological investigation, live cell imaging, genetic models, and laser microdissection combined with gene expression analysis. Complexly organized NEBs are an integral part of the intrapulmonary airway epithelium of all air-breathing vertebrates. For decades a quest has been going on to unravel the functional significance of these intriguing structures that appear to be modified in the course of many pulmonary diseases. The NEB microenvironment (ME) is composed of organoid clusters of pulmonary neuroendocrine cells (PNECs) that are able to store and release neurotransmitters and are closely contacted by extensive nerve terminals, emphasizing a potential receptor/effector role and probable signalling to the central nervous system. PNECs are largely shielded from the airway lumen by a special type of Clara cells, the Clara-like cells, with potential stem cell characteristics. So far, functional studies of the pulmonary NEB ME revealed that PNECs can be activated by various mechanical and chemical stimuli, resulting in a calcium-mediated release of neurotransmitters. In the past decades, a number of publications have exposed NEBs as potential hypoxia sensors. Recent experimental evidence unveiled that the NEB ME is a quiescent stem cell niche in healthy postnatal lungs, and silencing may involve bone morphogenetic protein signalling mediated by vagal afferents. Only an integrated approach that takes all current information into account will be able to explain the full role of the pulmonary NEB ME in health and disease. This highly informative and carefully presented book, provides insights for researchers, PhD students with an interest in (bio)medical and veterinary science, especially in the field of the autonomic innervation of the lung, chemo-and mechanoreceptors
