This fifth edition of "Engineering Physiology" has the same purpose as the earlier prints: to provide physiological information which engineers, designers, supervisors, managers and other planners need to make work and equipment "fit the human." Chapters have been revised, figures and tables updated. New material discusses, among other topics, models of the human body that provide practical and design-oriented information, biomechanics describing the body's capabilities and limitations, effects of shift work / sleep loss on attitude and performance, and new techniques to measure body sizes and the resultant changes in applications of that information. The book does not replace standard (biological-medical-chemical) textbooks on human physiology; instead, it provides information on human features and functions which are basic to ergonomics or human (factors) engineering, terms often used interchangeably. It helps lay the foundations for teamwork among engineers and physiologists, biologists and physicians. Bioengineering topics concern bones and tissues, neural networks, biochemical processes, bio- and anthromechanics, biosensors, perception of information and related actions, to mention just a few areas of common interest. Such understanding provides the underpinnings for devising work tasks, tools, workplaces, vehicles, work-rest schedules, human-machine systems, homes and designed environments so that we humans can work and live safely, efficiently and comfortably.
Biased Signaling in Physiology, Pharmacology and Therapeutics is a unique and essential reference for the scientific community concerning how conformational-dependent activation is a common phenomenon across many classes of receptors or signaling molecules. It discusses the role of conformational dynamics in leading to signaling bias across different classes of receptors and signaling molecules. By providing a broader view of signaling bias, this resource helps to explain common mechanisms shared across receptor classes and how this can be utilized to elucidate their cellular activity and better understand their therapeutic potential. Written for both new and established scientists in pharmacology, cell biology, biochemistry, and signal transduction, as well as physicians, this book clearly illustrates how biased receptor signaling can be utilized to develop and understand complex pharmacology. Chapters are each focused on a specific class of receptor or other important topic and make use of real-world examples illustrating how the latest research in signal transduction has led to a better understanding of pharmacology and cell biology. This structure creates a basis for understanding that physiological signalling bias has been selected by nature in order to provide complex and tissue- specific biological responses in the face of limited receptors and signaling pathways. This book provides a framework to reveal that these physiological mechanisms are not restricted to one receptor type or family and thus presents receptor signaling from a newer, more global perspective.
This book focuses on a development for assessing mental changes using eye pupil reactions, namely extracting emotional change from the response to evaluate the viewer's interest in visual information. The pupil of the eye reacts to both brightness and emotional state, including interest, enjoyment, and mental workload. Because pupillary change is a biological signal, various artifacts influence measurements of eye images. Technical procedures are required to extract mental activities from pupillary changes, and they are summarized here step by step, although some procedures contain earlier techniques such as analog video processing. This study examines the possibility of estimating the viewer's interest and enjoyment of viewing movies by measuring the dynamic pupillary changes, blinking, and subjective interest responses. In evaluation of pupil size, there was a significant difference in pupil size between the higher and the lower shot for the degree of subject interest response in each kind of movies. The first part of the book shows a pupil reaction model for brightness changes to extract mental activities. Pupil reactions were observed for various visual stimuli in brightness changes. With regard to the characteristics of pupillary changes, a model with a three-layer neural network was developed and the performance was evaluated. Characteristics of pupil reactions during model development are summarized here. The second part examines the possibility of estimating the viewer's interest and enjoyment of television programs by measuring dynamic pupillary changes, blinking, and subjective interest responses. The final part describes a development of estimation model of pupil size for blink artifact. The model development was able to estimate pupillary changes and pupil size while the viewer was blinking and was applied to pupillary changes in viewing television programs.

Even before the time of organized scientific investigation, hu mans had begun pondering and attempting to explain the work ing of the brain and the mental and behavioral states it produces. In the last twenty years there has been an almost explosive in crease in brain research. Beginning perhaps with the pioneering efforts of Francis O. Schmitt to establish the Neuroscience Re search Program and the later development of the Society for Neuroscience, there has emerged a large and powerful multi disciplinary research force devoted to understanding even the ru dimentary aspects of brain functioning. Chemists, physicists, and engineers with their special expert ise in quantitative physical measurements have teamed up with the neurobiologists, who best know the texture and design of brains, to produce particularly effective new approaches. No where is this more evident than in the recently developed meth ods like positron emission tomography and magnetic resonance imaging-techniques that allow one to observe on-going brain ac tivity in humans. This volume concerns a considerably more modest approach: the use of microelectrodes to electrochemically monitor certain aspects of chemical dynamics in functioning ani mal brain systems. The method provides signals that can be di rectly related to chemical neurotransmission. It is a relatively new technique, the first practical measurements having been made in the 1970s, and it is continuously undergoing refinement. The organizer of this book, Jay Justice, is eminently qualified for the task."
The volumes in this authoritative series present a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to nano- and microscopic events in a corrector scheme of regulated mechanisms. Therefore, investigation of flows of blood and air in physiological conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning. The present volumeis devoted to cellular events that allow adaptation to environmental conditions, particularly mechanotransduction.It begins with cell organization and a survey of cell types in the vasculature and respiratory tract. It then addresses cell structure and functions, especially in interactions with adjoining cells and matrix."
This volume describes our current understanding of the biological role of the delta-opioid receptor (DOR) system, focusing on its unique mechanisms of receptor trafficking and signaling in disease states. Part 1 covers the endogenous ligands that regulate the DOR system as well as novel compounds and therapies used to modulate the DOR system. Part 2 describes new insights into the localization and trafficking of the DOR and how ligand-directed signaling alters the fate of the receptor. Part 3 concentrates on the potential role of the DOR system in disease states, such as pain, mood, addiction, and Parkinson's disease. Throughout the book, the DOR system as a target for drug development will be discussed.
Heart Cell Coupling and Impulse Propagation in Health and Disease
includes an up-to-date review on how heart cells communicate and
impulse propagation under normal as well as under pathological
conditions. The complexity of intercellular coupling and impulse
propagation is discussed, providing the reader with a broad view of
the importance of these processes and how they contribute to the
generation of cardiac arrhythmias and heart failure. The different
aspects and intricacies of heart cell communication is discussed by
different authors, each one an expert in their own field.
Gasps, sighs, and yawns are recognized by even a casual observer as involuntary expressions of emotion through the "medium" of respiration. In recent years, scientific observation has focused on sensation and behavior as researchers investigate the relation of emotion and stress in disorders such as asthma, hyperventilation, and panic disorder. Until now, however, the interplay of psychological factors and physiological responses has not been approached from the interdisciplinary perspective reported in this book. Brought together here is the work of physiologists, psychologists, and researchers in behavioral medicine, together with - for the first time - specialists and practitioners of traditional Japanese arts and culture. Knowledge of the art and control of breathing, which are essential features of such disciplines as Zen and Noh, opens a new and until now unexplored path for scientists seeking to understand the relation between respiration and emotion.
An enormous amount of research is currently devoted to evaluating the role of nutrition in the aetiology of major human diseases and to clarifying the underlying mechanisms. This resurgent interest reflects the realisation that carcinogens may be generated during the normal cooking of food and that they may play a role in human carcinogenesis. Moreover, during the last decade it has become apparent that naturally occurring chemicals in food, primarily of plant origin, can afford effective protection against human cancer and heart disease. As a result, the need for up-to-date information in this subject area has never been greater. Nutrition and Chemical Toxicity deals in depth with the various toxicants found in food including naturally occurring chemicals, fungal contaminants, products of the cooking process and allergens. Other chapters focus on nutritional modulation of cytochromes P450; interactions between drugs and diet; glutathione, sulphur aminoacids and chemical detoxication; modulation of the carcinogenic response by caloric restriction; and lipotropes and chemical carcinogenesis. Further contributions discuss the expression of chemical toxicity in vitamin deficiency and supplementation; safety evaluation of vitamins and minerals; naturally occurring organosulphur compounds as potential anticarcinogens; cancer chemoprevention by tea polyphenols; and animal diets in safety evaluation studies. This timely book is essential reading for professionals involved in cancer research and the safety evaluation of chemicals, food scientists and toxicologists, nutritionists and those involved with food regulation.
With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

Only recently have we begun to appreciate the role of microbiome in health and disease. Environmental factors and change of life style including diet significantly shape human microbiome that in turn appears to modify gut barrier function affecting nutrient & electrolyte absorption and inflammation. Approaches that can reverse the gut dysbiosis represent as reasonable and novel strategies for restoring the balance between host and microbes. In the book, we offer summary and discussion on the advances in understanding of pathophysiological mechanisms of microbial host interactions in human diseases. We will not only discuss intestinal bacterial community, but also viruses, fungi and oral microbiome. Microbiome studies will facilitate diagnosis, functional studies, drug development and personalized medicine. Thus, this book will further highlight the microbiome in the context of health and disease, focusing on mechanistic concepts that underlie the complex relationships between host and microbes.
Studies of membrane transporters have had a great impact on our understanding of human diseases and the design of effective drugs. In Membrane Transporters in Drug Discovery and Development: Methods and Protocols, expert researchers provide practical methodologies of the ongoing research on membrane transporters, considering applications of transporter technologies in drug discovery and development. Chapters include new and useful fields and methodologies, including pharmacogenomics, nutrigenomics, systems biology, bioinformatics, nuclear magnetic resonance (NMR), imaging, and quantitative real-time-PCR. Transporter studies in drug discovery and development for various diseases are discussed, including neuropsychiatric disorders, cardiovascular diseases, ophthalmic diseases, cancer, and diabetes. Composed in the highly successful Methods in Molecular Biology (TM) series format, each chapter contains a brief introduction, step-by-step methods, a list of necessary materials, and a Notes section which shares tips on troubleshooting and avoiding known pitfalls. Wide-ranging and current, Membrane Transporters in Drug Discovery and Development: Methods and Protocols delivers a collection of practical protocols that can be used immediately in the lab, along with critical surveys of key topics by leading researchers in the field.
Cellular proteinases and their physiological role in normal and disease states have been the subject of great interest over recent decades. At present, specific protease inhibitors are exploited both as tools in unraveling the role of individual proteinases in particular cellular processes and for the development of chemotherapeutic agents for the treatment of various disorders. Proteinase and Peptidase Inhibition presents updated progress reports on the characterization of a wide range of cellular proteinases whose inhibitors may hold the key to the development of new drugs. Introductory chapters deal with the broad enzyme classes, inhibitor types and regulatory mechanisms governing proteinase activity. The target enzymes themselves, together with all aspects of their inhibition and inhibitor design, are comprehensively described. The classification of target enzymes by structural similarity, rather than by pharmacological effects, provides a new and coherent platform for understanding how inhibition of different targets can lead to the same therapeutic outcomes. This is a valuable reference book that will appeal to both academic and industrial researchers in the fields of medicinal chemistry, drug design and development, pharmacology, biochemistry, and molecular and cell biology.
Research has clearly established a link between omega fatty acids and general health, particularly cardiovascular health.

In addition to helping any nutrition investigator design and conduct appropriate research protocols in this area of nutrition, this book assists students who are planning to investigate amino acid and protein metabolism in humans or laboratory animals.
There has been a marked change in examination strategy over the last five years; EMQs (extended matching questions) are popular with tutors and students alike as they present a more realistic view of a student's ability to apply his or her knowledge in a clinical situation. The new edition of MCQs in Physiology has been subject to a complete overhaul to become MCQs and EMQs in Physiology. This reflects the current methods of examination techniques and will provide the student with a complete revision resource book. Packed with MCQs and EMQs along with clear and simple explanations of each answer, this book covers all the main physiological systems. The questions stretch from basic to applied and interpretative and are written with the modern integrated syllabus firmly in mind. Presented alongside other core revision books such as EMQs in Clinical Medicine this book will soon be seen as a must-have for any medie's shelf.

The ability to regulate and manipulate the generation or remodeling of blood vessels is key to the successful treatment of many chronic diseases, both oncological and non-oncological. Several bioactive compounds present in human diets are now known to exert an inhibitive effect on the either the signaling or construction of new blood vessels. The identification and characterization of these anti-angiogenic molecules opens a new avenue for the research and production of functional and medicinal foods with far reaching implications for the food-based treatment of chronic degenerative disease. Drawing from an extensive list of esteemed international contributors, Anti-Angiogenic Functional and Medicinal Foods explores the history and scope of the use of conventional foods, nutraceuticals, and health products in North America, Europe, the Middle East, Asia, India, Australia, and New Zealand. Recent advancements in proteomics, genomics, and toxicogenomics give us a far more detailed picture of the molecular basis of nutrition and systems toxicology. Explaining the role of angiogenesis in various chronic diseases, individual chapters consider endothelial cell responses, the mechanism of the angiogenic cascade, and the angiogenic function involved in tumors, cardiovascular disease, inflammatory arthritis, and obesity. A collection of chapters studies specific foods and their functional bioactive compounds such as the effects of edible berry anthocyanins, various Chinese medicinal foods, dietary flavonoids, probiotics, shark cartilage, EPA and DHA, and marine polysaccharides. The book concludes with a discussion of the challenges faced during the development and delivery of anti-angiogenic functional food products. Presenting the current research and state of the science, Anti-Angiogenic Functional and Medicinal Foods provides researchers, scientists, clinical nutritionists, and oncologists with a valuable reference to this important and growing mode of
Featuring practical strategies and exciting experiments, Teaching Innovations in Lipid Science addresses lipid education at a range of levels from the novice to the graduate student and teacher.
