This book explores how lighting systems based on LED sources have the ability to positively influence the human circadian system, with benefits for health and well-being. The opening chapters examine the functioning of the human circadian system, its response to artificial lighting, potential health impacts of different types of light exposure, and current researches in circadian photometry. A first case study analyzes the natural lighting available in an urban interior, concluding that it is unable to activate the human circadian system over the entire year. Important original research is then described in which systems suitable for artificial circadian lighting in residential interiors and offices were developed after testing of new design paradigms based on LED sources. Readers will also find a detailed analysis of the LED products available or under development globally that may contribute to optimal artificial circadian lighting, as well as the environmental sensors, control interfaces, and monitoring systems suitable for integration with new LED lighting systems. Finally, guidelines for circadian lighting design are proposed, with identification of key requirements.
A superb collection of time-tested, key techniques for investigating nervous system function, as well as the actions of drugs on the nervous system. The methods range from authoritative treatment of such well-established techniques as recording electrical activity in the brain, to practical coverage of state-of-the-art methods, including neural transplantation and antisense technology. The techniques described are particularly suitable for studying the mechanisms of action of psychotropic drugs and drugs of abuse, as well as the etiology and pharmacotherapy of neuropsychiatric diseases and neurodegenerative disorders. Several of the methods detailed are highly useful in screening potential drugs for the treatment of depression, anxiety disorders, schizophrenia, and Parkinson's and Alzheimer's disease.

The purpose of the present book is to amend and expand on James Houk's book (MIT press; ASIN: B010BF4U9K) by providing a comprehensive overview on computational models of the basal ganglia. This book caters to researchers and academics from the area of computational cognitive neuroscience.
Taurine, or 2-aminoethane sulfonic acid, has long been known to be the major organic product formed from the breakdown of the sulfur-containing amino acids, methionine and cysteine. It is excreted as such in the urine or as bile acid conjugates in the bile. Research over the last 25 years, however, has uncovered an amazing variety of phenomena involving taurine. Despite the fact that the mechanism of action of taurine in some of these phenomena remains to be elucidated, it is clear that taurine is of far more physiological relevance than being the mere metabolic debris of sulfur amino acid catabolism. It also has numerous pharmacological actions that are beginning to be developed, as exemplified by some of the studies reported in this volume. This volume reports the proceedings of the latest of a series of international symposia, continuing on from the initial meeting held in Tucson, Arizona, in 1975. The latest symposium was the first to be held in Germany, in Cologne from August 29 through September 1, 1993. It continued the multidisciplinary approach that has been the norm for taurine symposia. We hope the publication of the proceedings will stimulate further investigations on this simple but fascinating compound.
This book gives an up-to-date account of the current knowledge of cold adaptation in animals, including phenomena like hibernation, daily torpor, thermoregulation and thermogenesis, metabolic regulation, freeze tolerance, anaerobiosis, metabolic depression and related processes. For the next four years - until the 12th International Hibernation Symposium - it will serve as a state-of-the-art reference source for every scientist and graduate student working in these areas of physiology and zoology.
Drug addictions are often difficult to treat. The most successful treatments begin with studying why individuals become addicted to drugs and how to change their thinking and behaviour. Cognitive, Clinical, and Neural Aspects of Drug Addiction focuses on the theories that cause drug addiction, including avoidance behavior, self-medication, reward sensitization, behavioral inhibition and impulsivity. Dr. Moustafa takes this book one step further by reviewing the psychological and neural causes of relapse including the role of stress, anxiety and depression. By examining both the causes of drug addiction and relapse, this book will help clinicians create individualized treatment options for patients suffering from drug addiction.
Neurological Modulation of Sleep provides readers with updated scientific reviews regarding the interaction between sleep and contributing factors, with special attention paid to the potential for neurological modulation of sleep via diet. This book expands the notion of diet and adds an element of physical activity and exercise as well as a chapter on caffeine and its effects on sleep. With 30+ international contributors, this book aims to provide readers with a unique global perspective on the role these factors plays in sleep architecture and its regulation by circadian biology and neurology. Sleep disorders have become an increasing problem plaguing more than 70 million Americans according to the American Sleep Association. There is a clear association between sleep disorder and a wide range of other human disorders -performance deficiencies, psychiatric illnesses, heart disease, obesity and more - but in spite of this there is not yet a convenient overview on the market detailing the impact of obesity, age, diabetes and diet on sleep duration and attendant health outcomes.
This book highlights the impact of nutrients on early placentation processes and their relevance for fetal growth and pregnancy outcome. The role of maternal nutrition on fetal growth and development has been evidenced in many epidemiological studies that included infamous Dutch famine, Helsinki Birth cohort and others. Fetal programming hypothesis states that the nutritional and other environmental conditions under which an individual develops from pre-conception to birth has a major impact on the future health of the newborn child. The developmental environment of the fetus is primarily dependent on two major factors that are maternal nutritional state (excess/low/imbalance) and placental function. Placentation is characterized by the extensive remodeling of the maternal uterine vasculature producing low-resistance blood vessels that facilitate the exchange of nutrients and wastes between the mother and the fetus. Cellular and molecular mechanisms involved in human placental blood vessel formation, which are now well established, are discussed.
This book illustrates the importance and significance of oxidative stress in the pathophysiology of various human diseases.

This book systemically describes the mechanisms underlying the neural regulation of metabolism. Metabolic diseases, including obesity and its associated conditions, currently affect more than 500 million people worldwide. Recent research has shown that the neural regulation of metabolism is a central mechanism that controls metabolic status physiologically and pathophysiologically. The book first introduces the latest studies on the neural and cellular mechanisms of hypothalamic neurons, hypothalamic glial cells, neural circuitries, cellular signaling pathways, and synaptic plasticity in the control of appetite, body weight, feeding-related behaviors and metabolic disorders. It then summarizes the humoral mechanisms by which critical adipocyte-derived hormones and lipoprotein lipase regulate lipid and glucose metabolism, and examines the role of the hypothalamus-sympathetic nerve, a critical nerve pathway from CNS to peripheral nervous system (PNS), in the regulation of metabolism in multiple tissues/organs. Furthermore, the book discusses the functions of adipose tissue in energy metabolism. Lastly, it explores dietary interventions to treat neural diseases and some of the emerging technologies used to study the neural regulation of metabolism. Presenting cutting-edge developments in the neural regulation of metabolism, the book is a valuable reference resource for graduate students and researchers in the field of neuroscience and metabolism.

Blood Science is a relatively new discipline which merges biochemistry, haematology, immunology, transfusion science and genetics. This bringing together of traditional disciplines requires a corresponding change in education and training for healthcare scientists and Blood Science: Principles and Pathology is written in response to this emerging need. An introduction to the subject and an overview of the techniques used in blood science are followed by a series of chapters based on groups of analytes investigated in blood - red blood cells, white blood cells and platelets, followed by the constituents of plasma, including waste products, electrolytes, glucose, lipids, enzymes, hormones, nutrients, drugs, poisons and others. Each chapter is supported by learning objectives, summaries and further information, and a focus is given to chapter specific case studies with interpretation to demonstrate how laboratory data in conjunction with clinical details is utilised when investigating patients with actual or suspected disease. Finally, a separate chapter offers more detailed case reports that integrate the different aspects of blood science. Undergraduate students taking blood science modules as part of their BSc programmes in Biomedical and Healthcare Sciences will appreciate the level of integration between clinical biochemistry and haematology. In addition, this book will provide suitable initial reading for those students embarking on blood science modules on MSc programmes and will be of value to new graduates entering the profession and starting their career in blood science departments by supplementing practice-based training with the required theoretical underpinning. This book is approved by the Institute of Biomedical Science and written by its expert writers, many of whom work on the Institute s advisory panels.
Collateral blood vessels develop by growth of pre or newly formed structures in almost all vascular provinces as a consequence of progressing stenosis of the main artery. These alternative routes of blood supply are potentially able to alter the course of vascular disease. Collateral development is a time consuming process, and arterial stenosis and occlusion often progress faster than growth of the alternative routes. The authors' ultimate goal is to provide a better understanding of collateral growth in order to pave the way for improving the conditions for these potentially selfhealing processes. These were programmed by nature but have not been perfected, probably because defenses against arterial disease had not been put under the pressure of natural selection.

The first invasive evaluation of cardiac arrhythmias in humans was performed in 1967 in Paris (Prof. P. Coumel) and Amsterdam (Prof. D. Durrer). This was the start of a rapid increase in our knowledge of the diagnosis, mechanism and treatment of cardiac arrhythmias. In that same year Prof. Hein J.J. Wellens became cardiologist in the Wilhelmina Gasthuis in Amsterdam. Initially in Amsterdam (1967-1977) and later on in Maastricht (from 1977), he was the driving force for many breakthroughs in clinical cardiac electrophysiology. With an active interplay between the knowledge derived from the 12-lead electrocardiogram and the recordings made with invasive electrophysiology, he composed new ideas leading to major contributions in clinical cardiac electrophysiology and, more generally, in arrhythmology. He published over 650 scientific papers and 14 books, and had numerous functions within scientific boards of prestigious journals. In addition he trained more than 120 cardiologists in clinical cardiac electrophysiology. On the occasion of the congress `2000, Future of Arrhythmology: Lessons From the Past, Promises For Tomorrow', we highlight the scientific work of Prof. Hein J.J. Wellens. A selection of more than 60 articles over the whole time span has been selected. These articles are accompanied by comments from an expert, co-worker and/or former fellow in order to place the paper in a scientific time frame, including the relationship of the author with Prof. Hein J.J. Wellens.
'Earthing' introduces readers to the landmark discovery that living in contact with the Earth's natural surface charge - being grounded - naturally discharges and prevents chronic inflammation in the body. This effect has massive health implications because of the well-established link between chronic inflammation and all chronic diseases, including the diseases of ageing and the ageing process itself.

This unique volume will take you through the fascinating chronicle of prions in mammals, yeast, and fungi.
Introduction to Modeling in Physiology and Medicine, Second Edition, develops a clear understanding of the fundamental principles of good modeling methodology. Sections show how to create valid mathematical models that are fit for a range of purposes. These models are supported by detailed explanation, extensive case studies, examples and applications. This updated edition includes clearer guidance on the mathematical prerequisites needed to achieve the maximum benefit from the material, a greater detail regarding basic approaches to modeling, and discussions on non-linear and stochastic modeling. The range of case study material has been substantially extended, with examples drawn from recent research experience. Key examples include a cellular model of insulin secretion and its extension to the whole-body level, a model of insulin action during a meal/oral glucose tolerance test, a large-scale simulation model of type 1 diabetes and its use in in silico clinical trials and drug trials.
Exposure to space flight has been shown to results in changes in
many physiological systems, including the musculoskeletal system,
the cardiovascular system, the immune system, and the
neurovestibular system. These changes could negatively impact the
ability of humans to undertake long-term habitation and exploration
of space. However, there are limits to the studies that can be done
with humans in space. Both ground-based and space flight animal
model systems are currently used for these studies as an
alternative. This volume covers the latest developments in the use
of animal models to study the effects of the space flight
environment on human physiological systems.
Glutamate is the major excitatory neurotransmitter in the mammalian central nervous system (CNS). It regulates normal CNS function, is a major participant in pathology, and serves learning, memory, and higher cognitive functions. The 12 chapters of this book provide the first comprehensive coverage of all the major features of glutamate as excitatory neurotransmitter. The book begins with a valuable historical backdrop. Building from a chapter on the common structure of glutamate receptors, several others cover the major ionotropic receptors, their structure, function, and pharmacology. A follow-up chapter discusses the metabotropic receptors that are directly coupled to second messenger metabolism. A central theme of the book is the capacity of the excitatory amino acid system to contribute to the diverse array of signaling systems in the CNS as a direct result of the large assortment of receptors (including, for the ionotropic receptors, various subunits) the combination of which determine distinct functional properties. A recent development in the field discussed in several chapters is the biochemical characterization of a supermolecular protein complex, the post-synaptic density, that makes the unique structure of excitatory synapses. This complex subserves the experience-dependent modulation of synaptic strength and synaptic plasticity, and gives the synapse the capacity to change dynamically in both structure and receptor composition. Drawing on the individual properties of the receptors, transporters, and functional architecture of the synapse, the concluding chapters describe the functional integration of these components in the more complex physiological processes of plasticity and pathology. Recognition that the regulation of excitatory amino acid receptor activity underlies the pathology of many neurological diseases, including stroke, Alzheimer's disease and schizophrenia, has opened up an exciting frontier that will allow the translation of our understanding of these basic mechanisms into new concepts of pathology and new therapeutic strategies. This book will be invaluable for neuroscientists, pharmacologists, neurologists, and psychiatrists, and for their students and trainees.
Alzheimer's Disease Theranostics discusses the latest information on recent theranostic avenues for both the diagnosis and treatment of Alzheimer's patients.
