Rapid regeneration of city areas has placed the quality of urban design high on public and policy agendas worldwide. This work examines the achievement of quality in the urban environment, in a planning context. Tracing urban design from its roots, the authors draw on both historical and current practices to examine the key physical, political and economic forces at play and the social pressures and impacts brought about by both failures and achievements in urban design. This illustrated critique of towns and cities draws on examples from across Western Europe, South Africa and USA to examine both public and private sector development practices, controls and fiscal policies within a diverse range of localities. The authors indicate the need for a reinstitution of region-provincial approaches, for closer co-ordination bewteen sectors, and revised fiscal policies in planning and development in order to enhance the quality of urban social experience and environments.
The collection of chapters in this proceeding volume reflects the latest research presented at the Aegean meeting on Tumor Microenvironment and Cellular Stress held in Crete in Fall of 2012. The book provides critical insight to how the tumor microenvironment affects tumor metabolism, cell stemness, cell viability, genomic instability and more. Additional topics include identifying common pathways that are potential candidates for therapeutic intervention, which will stimulate collaboration between groups that are more focused on elucidation of biochemical aspects of stress biology and groups that study the pathophysiological aspects of stress pathways or engaged in drug discovery.

This monograph is dedicated to the lives and scientific achievements of the physiology pioneers Warren and Margaret Lewis. Their story spans the first half of the 20th century, from their respective educations through early, independent research to joint research from 1910 to 1955. Among the numerous developments they initiated, were the discovery of pinocytosis, the beginnings of video microscopy and the development of the first mammalian tissue cultures. Their research expanded the theoretical knowledge of cell structure and function. On a more practical level, they advanced many laboratory methods, like the first recipes for culture media. The text is beautifully enriched with personal anecdotes about their lives. This is the story of two scientific pioneers in the context of early 20th century biology and physiology. It is an inspiration for senior and aspiring researchers.
The maintenance of arterial blood pressure and the distribution of blood flow to the various organs of the body depends on the control of the pumping action of the heart and of the resistance of the vascular beds in the individual organs in accordance with their metabolic needs. These controls are achieved through the integrated actions of circulat ing hormones, humoral factors that are synthesized and released in the heart and blood vessels, and the autonomic nervous system. The heart, however, is not only the target for the direct and indirect actions of a number of hormones and humoral factors, it is also an endocrine organ in the traditional sense, synthesizing and secreting into the circulation chemical factors that act at distant sites. In this treatise, Hormones and the Heart in Health and Disease, we interpret "endocrinology" broadly and consider traditional hormones as well as autocoids that are secreted by the heart or that act on it. In this overview, the relevant chapters are indicated in parentheses. The discovery of atrial natriuretic peptide (ANP; atrial natriuretic factor, ANF) in the 1980s indicated that the heart does indeed function as an endocrine organ in the classic sense. ANP (Chapter I) is synthesized in the heart and secreted into the circulation for actions on the kidney, where it is a potent natriuretic agent, and on the vasculature, where it causes vasodilation. ANP can also affect myocardial contractility."
Quantitative ultrasound (QUS) of bone is a relatively recent research field. The research community is steadily growing, with interdisciplinary branches in acoustics, medical imaging, biomechanics, biomedical engineering, applied mathematics, bone biology and clinical sciences, resulting in significant achievements in new ultrasound technologies to measure bone, as well as models to elucidate the interaction and the propagation of ultrasonic wave in complex bone structures. Hundreds of articles published in specialists journals are accessible from the Web and from electronic libraries. However, no compilation and synthesis of the most recent and significant research exist. The only book on QUS of bone has been published in 1999 at a time when the propagation mechanisms of ultrasound in bone were still largely unknown and the technology was immature. The research community has now reached a critical size, special sessions are organized in major international meetings (e.g., at the World Congress of Biomechanics, the annual meetings of the Acoustical Society of America, International Bone Densitometry Workshop, etc...). Consequently, the time has come for a completely up to date, comprehensive review of the topic. The book will offer the most recent experimental results and theoretical concepts developed so far and is intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The central part of the book covers the physics of ultrasound propagation in bone. Our goal is to give the reader an extensive view of the mathematical and numerical models as an aid to understand the QUS potential and the types of variables that can be determined by QUS in order to characterize bone strength. The propagation of sound in bone is still subject of intensive research. Different models have been proposed (for example, the Biot theory of poroealasticity and the theory of scattering have been used to describe wave propagation in cancellous bone, whereas propagation in cortical bone falls in the scope of guided waves theories). An extensive review of the models has not been published so far. We intend in this book to present in details the models that are used to solve the direct problem and strategies that are currently developed to address the inverse problem. This will include analytical theories and numerical approaches that have grown exponentially in recent years. Most recent experimental findings and technological developments will also be comprehensively reviewed.
The volume Appetite Control provides a comprehensive description of the mechanisms controlling food intake, and thereby energy balance, in the mammalian organism. During the last decade, research in this area has produced a remarkable wealth of information and has characterized the function of numerous peptides, transmitters, and receptors in appetite control. Dysfunction of these circuits leads to obesity, a growing health concern. However, the plethora of mechanistic information is in marked contrasts to an almost complete lack of anti-obesity drugs that meet the safety standards required for the chronic therapy of morbid obesity. Consequently, ongoing research aims to identify additional targets and agents for a pharmacological intervention. Thus, the mechanisms of appetite control as well as all agents interfering with its control are of considerable practical interest. The authors of the volume are distinguished scientists who are leading experts in the field, and who have contributed important, original data to our understanding of the mechanisms of appetite control. They have quite different scientific backgrounds and, together, they represent all relevant disciplines. Thereby, the topics are presented from different points of view, not exclusively from that of pharmacology and neuroendocrinology. Thus, the volume addresses all scientists who are interested in the field of obesity research and the pathophysiology of appetite control."

Focusing mainly on in vitro methods, this volume gives techniques for isolation, culture and functional analysis of all bone cell types and details a range of imaging methods, including light and ultrastructural microscopy and live cell imaging. Some important in vivo techniques are included, such as analysis of bone resorption and imaging using X rays, fluorescent or luminescent techniques. Methods for study of proteins and nucleic acid are included and methods for analysis of bone composition, measurement of bone strength, and response to mechanical stimulation are described. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Bone Research Protocols, Second Edition seeks to aid scientists in the bone field to establish new techniques in their laboratories.
This accessible work is the first in more than seventy-five years to discuss the many roles of adrenaline in regulating the "inner world" of the body. David S. Goldstein, an international authority and award-winning teacher, introduces new concepts concerning the nature of stress and distress across the body's regulatory systems. Discussing how the body's stress systems are coordinated, and how stress, by means of adrenaline, may affect the development, manifestations, and outcomes of chronic diseases, Goldstein challenges researchers and clinicians to use scientific integrative medicine to develop new ways to treat, prevent, and palliate disease. Goldstein explains why a former attorney general with Parkinson disease has a tendency to faint, why young astronauts in excellent physical shape cannot stand up when reexposed to Earth's gravity, why professional football players can collapse and die of heat shock during summer training camp, and why baseball players spit so much. Adrenaline and the Inner World is designed to supplement academic coursework in psychology, psychiatry, endocrinology, cardiology, complementary and alternative medicine, physiology, and biochemistry. It includes an extensive glossary.
This second book of the three-volume collection "Ion Transport in Tumor Biology" helps readers gain comprehensive knowledge of the pathophysiology of cancer. The authors highlight that ion transport proteins, channels and transporters - collectively referred to as the transportome - are significantly involved in the development and progression of cancer. Nearly 90% of malignant tumor diseases originate from epithelial cells, the function of which, for the most part, is based on the transportome. This volume focuses on molecular principles by showing that dysregulated expression and/or function of ion transporters have been correlated with malignancy in the vast majority of tumor diseases. Within the story of the various chapters, the authors line out various malfunctions of the transportome and where they can be found at different stages of the metastatic cascade. The authors describe how the interactions between the tumor cells' transportome and the environment reinforce mesenchymal behaviour of cancer cells and contribute to their uncontrolled proliferation, migration, invasion, intra- and extravasation up to the formation of metastases. As part of a three-volume collection, this book will fascinate members of the active research community, as well as clinicians from the cancer field.
This volume is a record of the proceedings of a festspiel held to
honor Jozef F. Zwislocki for his outstanding contributions to
science and to Syracuse University. His contributions to the
knowledge of the hydromechanical, neurophysiological, and
perceptual mechanisms of the auditory system are truly monumental.
In addition, his contributions to the comprehension of the
mammalian auditory system include not only landmark ideas, but also
many of the experimental findings in psychoacoustics and peripheral
auditory physiology that constitute the database which has provided
a springboard for research in laboratories throughout the world.
His efforts to link physics, biology, and psychophysics to create a
basis for our understanding of the nervous system have had an
influence that extends far beyond the science of acoustics.
The result of the first Appalachian Conference on neurodynamics,
this volume focuses on processing in biological neural networks.
How do brain processes become organized during decision making?
That is, what are the neural antecedents that determine which
course of action is to be pursued? Half of the contributions deal
with modelling synapto-dendritic and neural ultrastructural
processes; the remainder, with laboratory research findings, often
cast in terms of the models. The interchanges at the conference and
the ensuing publication also provide a foundation for further
meetings. These will address how processes in different brain
systems, coactive with the neural residues of experience and with
sensory input, determine decisions.
There are many separate groups working in gut biology, and they feel that the gut is an excellent model for investigating general problems in differentiation, growth control, stem cell biology, and regeneration and adaptive responses. There is a pressing need to define the objectives of the next 5 to 10 years, and the meeting, Part III of the Gastroenterology Symposia Freiburg 1996 (Falk Symposium No. 94), held in Freiburg, Germany, October 25-26, brought together some of these groups with a view to identifying areas which are not being utilized and need to be exploited, such as transgenic and knockout approaches, retrovirus delivery systems, and model cell/tissue systems. The main themes of the book are gastrointestinal development and differentiation, gut stem cell biology, and the control of gut growth in normal and abnormal situations. Basic research findings are related to clinical situations, and the book will appeal not only to gut cell and molecular biologists, but also to gastroenterologists interested in the potential applications of these subject areas.

This book covers the tremendous progress in the current understanding of the molecular physiology of voltage-gated calcium channels. This book includes unparalleled insights into structural features of calcium channels due to X-ray crystallography and cryo-EM, which in turn yielded critical information into how these channels function under normal and pathophysiological conditions, and how they interact with calcium channel therapeutics. The chapters investigate how, with the advent of high throughput genome sequencing, numerous mutations in various calcium channel genes have been identified in patients with neurological, cardiovascular, neuropsychiatric and other disorders. This is further complemented through a much larger in vivo toolkit such as knock-out and knock-in mice. The chapters further discuss the increased complexity of calcium channel physiology that arises from mRNA editing and splicing. Finally, the book also provides an overview of the updated research on calcium channel inhibitors that can be used both in vivo and in vitro, and which may serve as a spring board for new calcium channel therapeutics for human disease. Voltage-Gated Calcium Channels is useful for academic researchers at all levels in neuroscience, biophysics, cell biology and drug discovery.
Measurement of Cardiac Deformations from MRI: Physical and Mathematical Models describes the latest imaging and imag analysis techniques that have been developed at leading centers for the visualization, analysis, and understanding of normal and abnormal cardiac motion with magnetic resonance imaging (MRI). The use of MRI in measuring cardiac motion is particularly important because MRI is non-invasive, and it is the only modality capable of imaging detailed intramural motion within the myocardium. Biomedical engineers, medical physicists, computer scientists, and physicians interested in learning about the latest advances in cardiovascular MRI should find this book to be a valuable educational resource. In particular, it is more tutorial in nature than most of the technical papers where the research was originally published. Practitioners and researchers working in the field of cardiovascular MRI will find the book to be filled with practical technical details and references to other work, enabling the implementation of existing methods and serving as a basis for further research in the area.
This volume introduces the concepts of income and optimal choice to
the realms of brain activity and behavior regulation. It begins by
developing the concept of the Income-Choice approach in the field
of biological control systems, then deals with the problems of
control of brain activity, and finally presents a model of behavior
disturbance based on the idea that its cause is a definite and
simple change in the income system of the organism. Other areas to
which the proposed Income-Choice approach could be applied are also
addressed including the origin of the epileptic aura and why it is
a predictor of the imminent attack, the mechanism of the phenomena
of "personality switching" in schizophrenics, and the possible
connection between schizophrenic- like symptoms and epileptic
status. Written nearly 20 years ago in Russia and now published in
the West, this book will be of value to many professionals in
related fields. This volume introduces the concepts of income and

This third and final volume in the "Ion Transport in Tumor Biology" collection presents novel diagnostic and therapeutic approaches in cancer based on the exploitation of ion transport proteins. The authors critically examine several transportome members, particularly Na+, K+, Ca2+, and Cl- channels, as well as organic solute carriers regarding their suitability as therapeutic targets. Synergistic effects resulting from the combined use of classical cytostatics with ion transport-inhibiting drugs are pointed out, and the capability of bispecific antibodies to function as anticancer drugs is discussed. As readers will also learn, the use of ion channel inhibitors could improve the outcome of radiotherapy because the development of radio-resistance during radiotherapeutic treatment often correlates with increases in the expression levels and conductance of ion channels. The translational topics of this volume form a bridge between biochemical research and therapeutic application. As part of a three-volume collection, this book will fascinate members of the active research community, as well as clinicians in the cancer field.
From Natural Character to Moral Virtue in Aristotle discusses Aristotle's biological views about character and the importance of what he calls 'natural character traits' for the development of moral virtue as presented in his ethical treatises. The aim is to provide a new, comprehensive account of the physiological underpinnings of moral development and thereby to show, first, that Aristotle's ethical theories do not exhaust his views about character as has traditionally been assumed, and, second, that his treatment of natural character in the biological treatises provides the conceptual and ideological foundation for his views about habituation as developed in his ethics. Author Mariska Leunissen takes seriously Aristotle's-often ignored-claim that nature is one of the factors through which men become 'good and capable of fine deeds'. Part I ('The Physiology of Natural Character') analyzes, in three chapters, Aristotle's notion of natural character as it is developed in the biological treatises and its role in moral development, especially as it affects women and certain 'barbarians'-groups who are typically left out of accounts of Aristotle's ethics. Leunissen also discuss its relevance for our understanding of physiognomical ideas in Aristotle. Part II ('The Physiology of Moral Development) explores the psychophysical changes in body and soul one is required to undergo in the process of acquiring moral virtues. It includes a discussion of Aristotle's eugenic views, of his identification of habituation as a form of human perfection, and of his claims about the moral deficiencies of women that link them to his beliefs about their biological imperfections. |
