Since the beginning of the 21st Century there has been a rapid increase in our understanding of the cellular trafficking mechanisms of molecular chaperones in eukaryotes and in prokaryotes. In the former, molecular chaperone trafficking can occur between the various cellular compartments, with concomitant movement of other proteins. Such events can also result in the release of molecular chaperones from cells. In bacteria, molecular chaperones are involved in the trafficking of other proteins and are themselves released into the external milieu. The increasing appreciation of the role of molecular chaperones and Protein-Folding Catalysts in the interplay between bacteria and the cells of their hosts is now an important area of research for understanding the mechanisms of infectious diseases. This volume brings together experts in the biochemistry, cellular biology, immunology and molecular biology of molecular chaperones and Protein-Folding Catalysts with a focus on the mechanisms of cellular trafficking of these proteins and the role of these variegated trafficking mechanisms in both human and animal health and disease.

The nitrogen-containing ring structures are at the hub of metabolism and include ATP, nucleic acids, many coenzymes, metabolic regulators and integrators such as adenosine and GTP, signalling compounds such as cyclic nucleotides and plant cytokinins and biochemically functional pigmets of which haemoglobin, the cytochromes and chlorophyll are examples. This important book collates and integrates current knowledge of all the biologically important N-heterocyclic compounds, covering the relationship between their chemical structures and physiological functions within this key group of compounds. Few biochemical reaction sequences do not involve one of these compounds as a substrate, product or coenzyme and a full understanding of the interrelationship between their structure and function is vital for all those woorking in the field of biochemistry. Professor Eric Brown who has a huge wealth of experience in teaching and research on these compounds has written a very comprehensible and thorough book which will be of great value for advanced students and researchers in biochemistry and those at the interfacing subject areas of chemistry, biology and pharmacology including all those employed in researching biological function within pharmaceutical companies.
The aim of this book is to present current views about physical activity and the benefits of physical activity in preventing and ameliorating various health conditions that are of worldwide concern. This book was developed as a compilation of the accomplishments of the five-year Global COE (Center of Excellence) "Sport Sciences for the Promotion of Active Life" Program at the Faculty of Sport Sciences of Waseda University, Saitama, Japan. The first part establishes the research methodology and discusses the current status of physical activity. Topics covered include the prevalence of physical inactivity and highly sedentary behavior in different populations as well as strategies that can be adopted to promote physical activity. The second part focuses on the physiological effects of physical activity. Topics covered include physiological responses to exercise by the autonomic nervous system, the endocrine system, vascular functioning, postprandial blood glucose control, and inflammatory processes. The relationship between exercise and appetite is discussed, as is the influence of exercise on food intake and weight regulation. Additionally, the influence of exercise on protein regulation and posttranslational modifications is introduced. The final part discusses the role of physical activity in preventing lifestyle-related health issues and improving the quality of life, especially for the elderly. The contents should be of interest to anyone who is concerned with the human physiologic response to exercise and the promotion of healthy lifestyles, including sports and exercise science researchers as well as those involved with medicine, public health, physiology, nutrition, and elder care.
Since its ?rst description in 1942 in both serum and cerebrospinal ?uid, transthyretin (TTR) has had an eventful history, including changes in name from "prealbumin" to "thyroxine-binding prealbumin" to "transthyretin" as knowledge increased about its functions. TTR is synthesised in a wide range of tissues in humans and other eutherian mammals: the liver, choroid plexus (blood- cerebrospinal ?uid barrier), retinal pigment epithelium of the eye, pancreas, intestine and meninges. However, its sites of synthesis are more restricted in other vertebrates. This implies that the number of tissues synthesising TTR during vertebrate evolution has increased, and raises questions about the selection pressures governing TTR synthesis. TTR is most widely known as a distributor of thyroid hormones. In addition, TTR binds retinol-binding protein, which binds retinol. In this way, TTR is also involved with retinoid distribution. More recently, TTR has been demonstrated to bind a wide variety of endocrine disruptors including drugs, pollutants, industrial compounds, heavy metals, and some naturally occurring plant ?avonoids. These not only interfere with thyroid hormone delivery in the body, but also transport such endocrine disruptors into the brain, where they have the potential to accumulate.
Methods in Bone Biology is unique in being devoted to describing the methodology used by bone researchers.

A qualitative leap in the understanding of cardiovascular and n- ral regulation by the renin-angiotensin system, and of the role of this s- tem in tissue damage, has occurred as a result of the many recent advances in molecular genetic techniques. The cloning of the genes for the components of the renin-angiotensin system, the design of specific angiotensin receptor ligands, and the use of embryonic gene targeting te- niques for the creation of mutant strains have established that the renin- angiotensin system is important in blood pressure regulation, ion and fluid homeostasis, and tissue growth and remodeling Further investigation of the mechanisms by which this system p- ticipates in cardiovascular regulation may shed some light on the pat- genesis of several cardiovascular diseases, e. g. , hypertension, congestive heart failure, and chronic renal failure. Despite the promise of this system as a target for therapeutic interventions for these diseases, there are great challenges in the integration of the attempts to close the gap between the traditional literature of medicine and the explosion of information from the new technologies. This book's title, Angiotensin Protocols, reflects the authors' strong efforts to translate expert knowledge into easy-to-follow practice. The book opens with introductory chapters, and each specialty section provides detailed methods covering a wide variety of techniques, ranging from genetic manipulation of targeted genes to functional studies of the renin- angiotensin system.
This award-winning thesis investigates the mechanisms underlying cardiac arrhythmia development and termination from an entirely new perspective. By viewing the heart as a complex system, the author uses theoretical tools from nonlinear dynamics combined with numerical simulations and experiments to achieve insights into the relationship between its structure and dynamics, thereby paving the way towards innovative low-energy defibrillation strategies. The work tackles, among other things: the effect of substrate heterogeneity on the spatial-temporal dynamics of cardiac arrhythmias and ways in which weak pulsed electric fields can be used to control these dynamics in heterogeneous cardiac tissue. The long-term vision of this research is to replace the current strategy of applying painful and sometimes tissue damaging electric shock - currently the only reliable way to terminate life-threatening fibrillation - by a more subtle but equally effective intervention. The book maps out a number of promising research directions for biophysicists and medical researchers working on the origins and treatment of cardiac arrhythmias.
Medical image technologies play a significant role in visualization and interpretation methods in medical diagnosis and practice using decision making, pattern classification, diagnosis, and learning. Progressions in the field of medical imaging lead to interdisciplinary discovery in microscopic image processing and computer-assisted diagnosis systems, and aids physicians in the diagnosis and early detection of diseases. Histopathological Image Analysis in Medical Decision Making provides emerging research exploring the theoretical and practical applications of image technologies and feature extraction procedures within the medical field. Featuring coverage on a broad range of topics such as image classification, digital image analysis, and prediction methods, this book is ideally designed for medical professionals, system engineers, medical students, researchers, and medical practitioners seeking current research on problem-oriented processing techniques in imaging technologies.
Death receptors play a central role in directing apoptosis in mammalian cells. This process of active cell death is important for a number of biological processes, e.g. for the regulation of the immune system. Death receptors are cell surface receptors that transmit apoptotic signals initiated by corresponding death ligands. Many complex signaling pathways are activated and apoptosis is the final result of a complex biochemical cascade of events. Besides their role in the induction of cell death, evidence now exists that death receptors are able to activate several non-apoptotic signaling pathways which, depending on cellular context, may lead to apoptosis resistance, secretion of pro-inflammatory proteins, proliferation and invasive growth of cancer cells. This book looks at the molecular basis of death receptor signaling and the role of death receptors in cancer development.
As the current millennium steams towards a close, one cannot help but look with amazement at the incredible amount of progress that has been achieved in medicine in just the last few decades. A key contributing factor to this success has been the importation and blending of ideas and techniques from disciplines outside the traditional borders of medical science. In recent years, the most well-known example is the cross-pollination between molecular biology and medicine. Advances driven by this potent combination have spawned the vision of a future where cures based on gene therapy become commonplace. Yet, as we continue our search for "magic bullets" in the quest to eradicate disease, it important to recognize the value of other less-heralded interdisciplinary efforts that have laid a large part of the foundation of present-day medicine. In pulmonary medicine, the contribution from the bioengineers (a diverse collection of individuals cross-bred to various degrees in mathematical modeling and experimental physiology) has been larger and more sustained than in many other medical specialties. It is easy to point to the vast array of ventilators, blood-gas analyzers, oximeters, pulmonary function devices, and respiration monitors that are present in any modern clinical setting as solid evidence of the successful synergy between engineering science and pulmonary medicine. However, one must not forget the less tangible, but perhaps more important, contributions that have been derived from mathematical modeling and computer simulation, without which many of these modern instruments would not have come into existence.

The number of mouse models that are available for the study of human genetic neurological disorders is large and growing rapidly. Therefore, it was difficult to select the models that were reviewed in this volume. Clearly, there are important models that are not discussed, and perhaps a volume twice this size would have been more appropriate. Moreover, the pace at which new models are being developed and analyzed is rapid. As this volume goes to press, I am sure that additional mouse genes responsible for naturally occurring neurological disorders are being discovered and that many new transgenic and mutant mouse strains are being developed. Therefore, this volume should not be viewed as a comprehensive compendium, but rather as an update of work in progress. It is exhilarating to witness the fast pace at which these models are being established as important tools in the study of basic neuroscience and neurological disorders. It will be even more exciting to see their utilization in the development and testing of therapeutic interventions for these diseases. I would like to thank each of the authors who have contributed to this volume for their time and their expertise. I would also like to thank Drs. Timothy Coetzee and Joshua Corbin for their advice in the selection of the topics covered. I am deeply indebted to Dr. Kunihiko Suzuki, who first approached me with the idea for this volume, for his guidance throughout its preparation.

The multiple actions of estrogens on different cell types have not only intrigued endocrinology researchers but also inspired the development of selective estrogen receptor modulators, or SERMs, that modulate estrogen signaling in a cell type-specific manner. Current molecular understanding of estrogen action has greatly profited from advances in molecular cell biology to dissect the mechanisms of estrogen-regulated gene expression in target cells, from in vivo analyses using genetic models deficient in estrogen signaling and from synthetic estrogen receptor ligands with isoform- or pathway-selective activity. These advances, and their implications for clinical use, were discussed by leading researchers from industry and academia during an international symposium held in Berlin, 1-3 March 2006.

Atherosclerosis leading to coronary heart disease and to cerebrovascular disorders is the number one cause of death in industrialized societies. For the last two decades, great ad vances have been made in understanding the pathogenesis of those disorders. Recent studies have revealed that the earliest event in atherogenesis is the adhesion of circulating leukocytes to the vascular endothelial cells and their migration into the subendothelial space. These cells are known to playa central role in the formation of a fatty streak consist ing of lipid-laden foam cells. As pathological events continue, the lesion is converted to a more fibrous lesion associated with vascular smooth muscle cells. To solve the enigma of this complicated process, intensive studies in molecular biology have disclosed the genes involved in those events. Some of the genes have been verified by creation of novel animal models, which have led to novel therapeutic strategies for subjects with atherosclerosis. This volume contains papers presented at the International Symposium on Lipoprotein Metabolism and Atherogenesis held in Kyoto December 5-8, 1998, supported in part by the Japan Intractable Diseases Research Foundation. The following three topics were the focus of the three-day program: I) The molecular approach to studying risk factors and prevention 2) The creation of novel animal models 3) Lipoprotein disorder as a cause of activation of vascular endothelial cells Thirty distinguished researchers from the United States, the United Kingdom, Austria, Finland, Australia, and Japan were invited.
Research over the years has demonstrated that free radicals mediated oxidative stress lies at the helm of almost all patho-physiological phenomena. These findings emphasize on the need to understand the underlying molecular mechanism(s) and their critical role in the pathogenesis. This book aims to focus on these areas to provide readers a comprehensive outlook about the major redox sensitive pathways and networks involved in various disease conditions. In the first chapter of the book, basic information about the oxidative stress, its generation, its biomarkers and its role in body are discussed. In the next three chapters, the role of oxidative stress in various pathologies ranging from neurological disorders, to cardiovascular diseases, cancers, metabolic diseases and ageing have been described. Chapter 5 cumulatively describes the most important molecular signaling pathways that are affected by reactive oxygen species (ROS). These are the mechanisms which are common denominators in various pathological states. In the next part of the book, various antioxidant strategies to target and mitigate ROS have been discussed with details on the mechanisms. Selenium, being the research focus and interest of the authors for years, the role of selenium as an antioxidant as part of selenoproteins has been included in the book. Finally, the book culminates with authors' perspective on the future of the redox biology field. Throughout the book, efforts have been made to use simplified language and suitable figures for ease to understand the contents. Although the authors have tried to touch on all the different aspects of oxidative stress in detail, the fact that it is a continuously growing field with updates coming every day, there might be some areas which might not be described in depth. This book is designed for students, young scientists to get acquainted with the redox biology. Overall, this book is a reference to understand the redox regulation of cellular signaling pathways involved in pathogenesis. |
