Nutritional Biochemistry takes a scientific approach to nutrition.
It covers not just "whats"--nutritional requirements--but why they
are required for human health, by describing their function at the
cellular and molecular level. Each case study either leads to a
subsequent discovery or enables an understanding of the
physiological mechanisms of action of various nutrition-related
processes. The text is "picture-oriented" and the commentary is
directed towards explaining graphs, figures, and tables.
The role of vitamin A in living organisms has been known throughout human history. In the last 100 years, the biochemical nature of vitamin A and its active derivative, retinoic acid, its physiological impact on growth processes, and the essential details of its mechanism of action have been revealed by investigations carried out by researchers using vertebrate and more recently invertebrate models to study a multiplicity of processes and conditions, encompassing embryogenesis, postnatal development to old age. A wealth of intercellular interactions, intracellular signaling systems, and molecular mechanisms have been described and the overall conclusion is that retinoic acid is essential for life. This book series, with chapters authored by experts in every aspect of this complex field, unifies the knowledge base and mechanisms currently known in detailed, engaging, well-illustrated, focused chapters that synthesize information for each specific area. In view of the recent information explosion in this field, it is timely to publish a contemporary, comprehensive, book series recapitulating the most exciting developments in the field and covering fundamental research in molecular mechanisms of vitamin A action, its role in physiology, development, and continued well-being, and the potential of vitamin A derivatives and synthetic mimetics to serve as therapeutic treatments for cancers and other debilitating human diseases. Volume II is divided into nine chapters contributed by prominent experts in their respective fields. Each chapter starts with the history of the area of research. Then, the key findings that contributed to development of the field are described, followed by a detailed look at key findings and progress that are being made in current, ongoing research. Each chapter is concluded with a discussion of the relevance of the research and a perspective on missing pieces and lingering gaps that the author recommends will be important in defining future directions in vitamin A research.
This book focuses on established cardiovascular principles and highlights some of the progress achieved by recent research in the cardiovascular field. The authors report the basic concepts related to the functioning of the cardiovascular system necessary for medical students to understand. To foster learning, in each chapter the fundamental points are highlighted in italics and/or bold. In addition, we have added boxes that contain some more detailed information about physiological mechanisms or clinical aspects are analyzed and described in greater detail. The book describes the structure and function of the heart and vascular system for the reader to understand how the cardiovascular system responds in both health and disease. The book conveys a unified vision of the function of the heart and the vascular system, explaining the complexity of the system that goes far beyond the integrated connection between preload, afterload and cardiac contractility. The endothelium covers the internal part of the whole cardiovascular system; therefore, endothelial physiology is treated in several chapters. Given the importance of coronary circulation in cardiac pathophysiology, this special circulation is described in detail and enriched with the most up-to-date information. Several paragraphs and boxes on clinical implications are dedicated to the principles of electrophysiology and the electrocardiogram. A space is also dedicated to myocardial ischemia/reperfusion injury and cardioprotective procedures. The book is written in a linear and simple language without compromising the scientific rigor of the various topics covered.
Nikolai Aleksandrovich Bernstein was one of the great neuroscientists of the twentieth century and highly respected by Western scientists even though most have never read his most important book entitled On the Construction of Movements. Bernstein's Construction of Movements: The Original Text and Commentaries is the first English translation. It supplements the translated text with a series of commentaries by scientists who knew Bernstein personally, as well as leaders in related fields including physics, motor control, and biomechanics. While written in 1947, Bernstein's book is anything but obsolete, making this English translation and accompanying commentaries an invaluable text. The translated original text presents in detail Bernstein's views on the evolutionary history of biological movement and his multi-level hierarchical scheme of the construction of movements in higher animals, including humans. The following commentaries address Bernstein's personality, the history of the book, and current views on different aspects of neuroscience covered in Bernstein's text. Ultimately, they present "a book within the book" to showcase how Bernstein's heritage has developed over the past years. This classic, available for the first time to an English-speaking audience, will prove beneficial to students, instructors, and experts of neuroscience, physics, neurophysiology, motor control, motor rehabilitation, biomechanics, dynamical systems, and related fields.
Blood coagulation and fibrinolysis has been traditionally classed as a part of hematology and the complement system as a part of immunology. An analysis of these two systems at a molecular level, however, has revealed some intriguing evolutionary relationships among some of the macromolecules involved. Evidently, there are similarities in the cascade of reactions that characterize the processes. It is therefore highly suitable that these topics are presented together in one volume. This book presents a thorough explanation and analysis of our current understanding of the proteins and enzymes involved in each of the three processes, and includes a section devoted to special topics of relevance, such as the kinin system, glycosylation, signal peptides, and the serpin family.
The Resistance Arteries is focused on the general issue of the regulatory pathways in resistance arteries and comprises a selection of timely overviews and up-to-date research studies presented at the 4th International Symposium on Resistance Arteries. These small vessels act as major controllers of blood pressure, blood flow, and its distribution, and are involved in a variety of pathological conditions. Vascular diameter is influenced by a host of factors, some extrinsic to the smooth musc1e cells and some intrinsic. One will find contributions in nearly all of the five themes by which the book is organized; these address intra-and extracellular interactions, and membrane receptor pathways using vascular beds as diverse as the brain, he art, lung, kidney, and skin. Basic physiological studies are inc1uded; these examine: growth fac tors, vasoactive endothelium-derived nitric oxide, the impacts of flow and stretch, myogenic mechanisms, calcium regulation by protein kinase C, and signal transduction pathways of the vascular smooth musc1e cell membrane receptors. Not only are tissues from appropriate animal models exploited in most of these reports, but many reflect the current increase in the use of human tissue to elucidate vascular alterations of function and morphology in hypertension, atherosclerosis, and ischemia. Noteworthy among the many techniques used are: membrane permeabilization with toxins, fura-2 for calcium determination, single cell electrophysiology, and the application of confocal microscopy to isolated, living vessels."
In most industries, musculoskeletal injuries are the most common work-related reason for employee absences. These injuries are often caused by static postures or repetitive movements that have to be maintained for many hours a day, such as intensive use of data entry devices, assembly work, parts inspection, equipment maintenance, manual materials handling, machinery operations, and vehicle operation, among others. The book addresses seating concepts, hand tool and pedal designs, foot-floor interfaces, digital human models for computer-aided design and engineering, and work organization (task duration, breaks, handling frequency) as they affect human performance and musculoskeletal injury reduction. Professionals responsible for identifying and improving conditions in the industries where such workplace injuries occur will find this volume to be a handy sourcebook, while teachers and students will find it to be a valuable reference.

The data and R computer programs are publicly available, allowing readers to replicate the model development and data analysis presented in each chapter, so that these new methods can be readily applied in their own research. The book also discusses recent developments in statistical modelling and data analysis in microbiome research, as well as the latest advances in next-generation sequencing and big data in methodological development and applications. This timely book will greatly benefit all readers involved in microbiome, ecology and microarray data analyses, as well as other fields of research.
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."

Vascular diseases, particularly atherosclerosis, are the most frequent and critical underlying fatal disorders in the industrialized world. Cardiovascular deaths are the leading cause of death in the Western world. Although cancer or malignant neoplasms recently have topped the list of causes of deaths in Japan, cardiovascular and cerebrovascular diseases bring about more deaths than cancer if they are reclassified into a unified category of diseases of the vascular system. The National Cardiovascular Center was established by the Ministry of Health and Welfare of Japan to combat cardiovascular and cerebrovascular diseases. Since the Center was opened, we have continued to support basic and clinical sturlies of cardiovascular and cerebrovascular diseases within as weil as outside the Center. Clinical studies that we have supported in modern diagnostic and therapeutic measures against cardio- and cerebrovascular diseases have made remarkable advances in recent years, especially in medical imaging technology including CT and MRI, and in interventional measures including balloon angioplasty and other catheter-based treatments. We are proud of the significant improvement in the overall survival rate and the quality of life of patients suffering from vascular disorders. However, there are still many essential difficulties remaining in the diagnosis and treatment of vascular disorders. Such difficulties necessitate further fundamental studies not only from the practical aspect but also from the integrated perspectives of medicine, biology, and engineering.
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.
The mechanical features of human movement are of great interest in a range of endeavors, from engineers designing car seats or keyboards to physicians treating sports injuries. Human movement obeys basic laws that govern static and dynamic bodies, and this textbook takes a quantitative approach to studying human biomechanics. The book features numerous homework problems and worked examples, both of which are vital for classroom use. The book will be welcomed by teachers of engineering mechanics, statics and dynamics, and biomechanics courses that assume familiarity with calculus and vectors. |
