Leading researchers are specially invited to provide a complete understanding of a key topic within the multidisciplinary fields of physiology, biochemistry and pharmacology. In a form immediately useful to scientists, this periodical aims to filter, highlight and review the latest developments in these rapidly advancing fields.
The great variety in structure and function of arthropod sensory organs is due to the huge number of species living in spatially and temporally different environments and to great variation in behavioral patterns. This atlas compiles the electron microscopic anatomy of arthropod sensory organophotoreceptors, chemoreceptors, and others in relation to function, behavior, and environment. The authors show how each sensory receptor is finely tuned to detect the necessary information in the arthropods surroundings and how the sensory receptors dynamically change their fine structures according to their functional and adaptational states. In each two-page spread of the book, electron or light micrographs are shown on the right, with diagrammatic illustrations and accompanying text on the left, in a format that is attractive and easy to understand. The atlas thus provides an important bridge between the physiology and morphology of arthropod sensory receptors.
The most recent research findings on the important genes, key
molecules, and mechanisms in neural development and regeneration
are presented in this volume. The papers collected here were
delivered at the second of the Keio University International
Symposia for Life Sciences and Medicine, held in Mita (Tokyo),
Japan, and are in eight main sections: Early Neurogenesis and
Pattern Formation, Regional and Cellular Specification, Trophic
Factors, Adhesion Molecules, Glial Cell Lineage and Myelination,
Circuit Formation, Synaptic Refinement and Neurotransmitter
Release, and Neural Regeneration. Together, they present the
concept of neural development and regeneration and its vital
importance at the frontiers of medical science today.
New Frontiers in Angiogenesis starts with a comprehensive overview of the field and continues with topics that have been minimally explored. The topics deal with dynamics of vasculogenesis using imaging techniques, bone marrow-derived endothelial cell precursors as potential therapeutic tools, regulation of post-angiogenic vessel regression, vascular mimicry, design and construction of artificial vessels, bioengineering of angiogenesis, and lymphangiogenesis recapitulating angiogenesis in health and disease states. Each chapter is written by leading experts of the subjects. It is hoped that this volume will challenge all of us interested in the field of angiogenesis and cardiovascular biology, in particular those in academia and industries, to think "outside the box" and explore angiogenesis from a fresh angle. It is hoped that New Frontiers in Angiogenesis is thought provoking and serve as a road map for discovering new findings to help betterments of human health.
Protein transport events occurring at the endoplasmic reticulum (ER) of eukaryotic cells and the cytoplasmic membrane of prokaryotic organisms share many similarities. Resident proteins of both membranes span the lipid bilayer once or several times by a-helical stretches and their integration is usually mediated by uncleaved signal-anchor sequences. Proteins that are translocated across either membrane, collectively also termed secretory proteins, harbour cleavable N-terminal signal sequences. Prokaryotic and eukaryotic signal sequences have the same modular structure and are functionally exchangeable. Integration of membrane proteins and translocation of secretory proteins basically occur at the same sites (pores) within each membrane. In both types of membranes, these pores are c- posed of homologous components forming the Sec translocons. Parts of the Sec trans- cons are found populated by ribosomes, the membrane-bound ribosomes. Bacterial m- brane and eukaryotic secretory proteins are targeted to the Sec translocons by the same molecular mechanism involving signal recognition particle (SRP) and its receptor (SRP - ceptor, SR). Structure and assembly of the SRP The functional core of SRP The functional core of this ribonucleoprotein complex consists of the signal sequence binding subunit (SRP54 in eukaryotes and Ffh in prokaryotes) and the SRP RNA molecule (see Fig. 1). This core is conserved in all organisms, with the intriguing exception of chloroplasts, where the SRP lacks the RNA subunit.
Interest in angiogenesis research remains strong in recent years and exciting new discoveries, about modulators of angiogenesis, their receptors, the transduction mechanisms and the angiogenic genes involved, have contributed to our present day understanding of this complex process. This knowledge has provided the basis and broadened the scope of angiogenesis - based therapy in oncology and many other clinical conditions. This monograph contains the contributions to the NATO Advanced Study Institute on "Angiogenesis: Models, Modulators and Clinical Applications," which was held in Rhodes, Greece, from June 20-30, 1997. This was the fourth of a series of NATO supported international meetings on Angiogenesis aiming to bring together basic scientists with clinicians to exchange ideas, disseminate new knowledge and discuss the present status and potential new directions in this fast moving area of biomedical research. The International Organising Committee that included Drs. E. Dejana, C Haudenschild, M. Hackel, H. Kleinman, P. Lelkes, M. Presta, P. Polverini, D. Thompson, has provided invaluable help with their insightful suggestions in the formulation of the scientific program for which I am grateful. I wish to thank all the participants for their enthusiastic participation and their complimentary comments on the success of the conference.

Novel Approaches into the Origins of Neurodevelopmental Disorders: The Fetal Physiology Foundation Over the past two decades, autism, a neurodevelopmental disorder that is defined by behavior and was once believed to be rare, became recognized in increasing numbers of children and recently received distinction as an "epidemic" [1]. While numbers of affected children have steadily increased, our knowledge is still ins- ficient to explain autism's diverse causes and broad range of presentations. Despite remarkable progress in research, available medical diagnostic testing applies only to a small minority of affected children. Thus, scientifically based explanations with which physicians can diagnose and treat the majority of children with autism and advise their parents are quite limited. Our society and scientific community were unprepared for the rise in autism, which explains our present inability to understand most of its causes. Researchers in neurodevelopmental disorders have long been aware of other disorders that, despite extensive efforts, have not yielded clear genetic or environmental origins, and autism has become symbolic of the need for new approaches to research into these complex conditions. Although autism has captured our attention in recent years, the prevalence of other neurodevelopmental disorders such as attention de- cit hyperactivity disorder (ADHD) and bipolar disorder, among others, also has been increasing [2-4].
This edition of the companion volumes Muscle Pain: Understanding the Mech- isms and Muscle Pain: Diagnosis and Treatment is essential reading for those interested in clinical approaches to acute and chronic pain conditions involving muscle tissues and in the mechanisms underlying these conditions. The volumes cover a very important topic in pain medicine, since muscle pain is very common and can often be dif?cult to diagnose and treat effectively. Furthermore, chronic pain involving muscle and other components of the musculoskeletal system increases with age, such that it is a common complaint of those of us who are middle-aged or older. Indeed, as changing population demographics in "west- nized" countries result in higher proportions of the population living longer and being middle-aged and elderly, chronic muscle pain will likely become even more of a health problem. In the case of acute muscle pain, this can often be very intense, and in the short term can limit or modify the use of components of the musculoskeletal system associated with the sensitive muscle. Chronic muscle pain can also be intense, as well as unpleasant and disabling, and it is in many cases the over-riding symptom of most musculoskeletal disorders that are associated with long-term deleterious changes in musculoskeletal function.
This book presents cutting edge methods that provide insights into the pathways by which salt and water traverse cell membranes and flow in an orchestrated fashion amongst the many compartments of the body. It focuses on a number of molecular, cellular and whole animal studies that involve multiple physiological systems and shows how the internal milieu is regulated by multifactorial gene regulation, molecular signaling, and cell and organ architecture. Topics covered include: water channels, the urinary concentrating mechanism, angiotensin, the endothelin system, miRNAs and MicroRNA in osmoregulation, desert-adapted mammals, the giraffe kidney, mosquito Malpighian tubules, and circadian rhythms. The book highlights how different approaches to explaining the same physiological processes greatly increase our understanding of these fundamental processes. Greater integration of comparative, evolutionary and genetic animal models in basic science and medical science will improve our overall grasp of the mechanisms of sodium and water balance.

Topics covered in this volume include the regulation of myocardial proteins in mechanical overload, the alteration of adrenoceptors in the stressed heart, metabolic adaptation in cardiac hypertrophy, intracellular calcium metabolism in the ischemia-reperfused myocardium, calcium overload as a cause of myocardial stunning, acquisition of ischemic tolerance by ischemic preconditioning, factors that accelerate myocardial injury, and ventricular remodeling in the ischemic heart. As an update of the latest findings in basic cardiology, this book will benefit both researchers and clinical practitioners.
The VIth World Symposium on Cardiac Pacing in Montreal 1979 opened with a course, meant to be an introduction for newcomers and an updating re fresher and link between the various fields of knowledge needed by experienced persons for cardiac pacing. Invited guest lecturers were selected for their world recognized expertise in the individual subjects. This book is a collection of the various presentations on historical, clinical, electrophysiological and technical aspects of cardiac pacing. Together they cover the fundamentals of cardiac stimulation. We hope that this book may become an introductory guide to the field of cardiac pacing and that it may contribute to a better understanding of the pacemaker system and a better treatment of the pacemaker patient.

Recent Advances in Prolactin Research summarizes the current knowledge of prolactin (PRL), PRL receptor, PRL-dependent signaling pathways, the role of PRL in oncogenesis and PRL crosstalk with other oncogenic factors. The chapters are written by experts in these fields and focus on identifying and reviewing timely experimental findings that provide new insights into the expanding role of PRL in the pathophysiology associated with a variety of human conditions. Prolactin is a peptide hormone that is best known for its role in lactation. Prolactin also has an influence on hematopoiesis and angiogenesis, and is involved in the regulation of blood clotting through several pathways. Although PRL was discovered more than 80 years ago, the understanding of PRL signaling and its relationship to various pathologies is still very incomplete. PRL is not only a pituitary hormone with an important role in reproduction, but PRL also acts as a cytokine, modulating a wide variety of physiological processes. For example, data gathered during the last decade have demonstrated that locally produced PRL acts as the autocrine/paracrine factor and plays a contributory role during breast oncogenesis. In fact, the scientific and clinical communities have suggested that the manipulation of the PRL axis may lead to the successful treatment of breast cancer. However, recent work has demonstrated that the role of the PRL axis is much more complex than first envisaged.

The bright colour of haemoglobin has, from the very beginning,
played a significant role in both the investigation of this
compound as well as in the study of blood oxygen transport.
Numerous optical methods have been developed for measuring
haemoglobin concentration, oxygen saturation, and the principal
dyshaemoglobins in vitro as well as in vivo. Modern applications
include pulse oximeters, fibre optic oximeters, multiwavelength
haemoglobin photometers ('co-oximeters') and instruments for near
infrared spectroscopy in vivo. Knowledge of the light absorption
spectra of the common haemoglobin derivatives is a prerequisite for
the development and understanding of these techniques.
Gastric acid plays a primary role in digestion as well as in the sterilization of food and water. Gastric juice contains the most concentrated physiological acid solution (pH~1) as a result + - of H and Cl ion secretion [hydrochloric acid (HCl) production] by parietal cells in the oxyntic mucosa of the stomach. The combined output of the parietal cells leads to the sec- tion of 1-2 l of HCl at a concentration of 150-160 mmol/l into the interior of the stomach. In order to facilitate the production of acid, the parietal cell relies on the generation of a high + concentration of H ions that are transported into the lumen of the gland. This process is fa- + + cilitated by activation of the gastric H ,K -ATPase, which translocates to the apical pole of + - the parietal cell. K as well as ATP hydrolysis and Cl all play critical roles in the activation + + of gastric H ,K -ATPase and are essential for the functioning of the enzyme (Reenstra and Forte 1990). This review will examine the classical proteins that have been linked to acid secretion as well as some recently identi?ed proteins that may modulate gastric acid secretion, in - dition we discuss the known secretagogues, and their receptors including a new receptor, which upon stimulation can lead to acid secretion.
The Sapporo International Symposium on "Recent Advances in Nitric Oxide Research" was held in Sapporo, Japan, in 1997, following the Fifth International Meeting on the Biology of Nitric Oxide in Kyoto, Japan, organized by Dr. Salvador Moncada, Dr. Noboru Toda, and Dr. Hiroshi Maeda. The field of nitric oxide research continues to expand rapidly, and our understanding of the physiological and pathophysiological roles of NO has increased greatly. The Kyoto Meeting was stimulating and informative, providing impetus for the Sapporo Symposium, which I had the great honor to organize. To communicate the information from these events, Dr. Ichiro Sakuma and I decided to publish this book. The contents of its chapters were contributed by the participants who were active at the Sapporo symposium and cover the majority of the presentations made during that symposium. Dr. Csaba Szabo of Children's Hospital Medical Center in Cincinnati (U. S. A. ) reviews the roles of peroxynitrite and poly(ADP-ribose)synthetase in shock, inflammation, and reperfusion injury, and Dr. David A. Geller and his colleagues of the University of Pittsburgh (U. S. A. ) review the regulation and function of NO in the liver. As contributions from the Hokkaido University School of Medicine (Sapporo), Dr. Hiroko Togashi and colleagues present their data on transient cerebral ischemia and NO production, Dr.

This well-established and acclaimed textbook introducing the rapidly growing field of nerve and muscle function has been completely revised and updated. Written with undergraduate students in mind, it begins with the fundamental principles demonstrated by the pioneering electrophysiological experiments on cell excitability. This leads to more challenging material recounting recent discoveries from applying modern biochemical, genetic, physiological and biophysical, experimental and mathematical analysis. The resulting interdisciplinary approach conveys a unified contemporary understanding of nerve and skeletal, cardiac and smooth muscle function at the molecular, cellular and systems levels. Emphasis on important strategic experiments throughout clarifies the basis for our current scientific views, highlights the excitement and challenge of biomedical discovery, and suggests directions for future advances. These fundamental ideas are then translated into discussions of related disease conditions and their clinical management. Now including colour illustrations, it is an invaluable text for students of physiology, neuroscience, cell biology and biophysics.

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.
