Protein degradation has been identified as a major mechanism for the regulation of cellular functions. Not surprisingly, its deregulation is implied in almost any pathological condition. This book describes how aged proteins are eliminated during cell metabolism, how cell proliferation is regulated by protein degradation and how its deregulation can contribute to the development of cancer, how protein degradation is modified during normal and abnormal aging, in particular with regard to Alzheimer's disease and other degenerative diseases of the brain and central nervous system. Attempts aiming at correcting these pathologies by interfering with deviations of the normal pathway of protein degradation are also treated.
There has been a tremendous amount of scientific progress in our understanding of the molecular mechanisms of transport processes in the liver within the last few years. Cloning of various members of organic anion and cation transporters has provided the necessary tools to study their regulation under physiological and pathophysiological conditions and has advanced our knowledge about bile formation. Mutations of various hepatic organic anion transporters have been identified in humans as hereditary defects leading to the heterogenous syndrome of progressive familial intrahepatic cholestasis (PFIC). Various mouse models including knockout animals have given us the opportunity to gain insight into lipid transport by the liver and the genetics of cholesterol gallstone formation. The physiology of bile duct cells and the molecular mechanisms leading to various cholangiopathies have been a main scientific focus in hepatology in recent years. Drug targeting to the liver by hepatic organic anion transporters represents an attractive way of selective delivery of pharmaceutical agents in humans. Ursodeoxycholic acid is successfully used in the treatment of patients with chronic cholestatic liver disease and major advances have been made in understanding its mode of action in liver and bile duct cells. This book, the proceedings of the Falk Workshop held in Aachen, Germany, on 25-26 January 2001, contains chapters on all important aspects of biliary transport by well-known experts in this field. It is an essential resource for new developments in the field of biliary transport, both in basic science and clinical medicine.
This book introduces the UTCI (Universal Thermal Climate Index) and summarizes progress in this area. The UTCI was developed as part of the European COST Action Program and first announced to the scientific community in 2009. Since then, a decade has followed of applicability tests and research results, as well as knowledge gained from applying the UTCI in human adaptation and thermal perception. These findings are of interest to researchers in the interdisciplinary areas of biometeorology, climatology and urban planning. The book summarizes this progress, discussing the limitations found and provides pointers to future developments. It also discusses UTCI applications in the areas of human biometeorology and urban planning including possibilities of using UTCI and similar indices in climate-responsive urban planning. The book's message is illustrated with many case studies from the real world. Chapter 10 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

In addition, problematic issues in pulmonary medicine are discussed at length. These issues, notably, concern human studies that have set the standards for allergy, sensory irritation, and sensitization research, as well as studies on the management and treatment of chronic obstructive pulmonary disease and obstructive sleep apnea. Lastly, the book addresses various aspects of commonplace viral respiratory infections, such as vulnerability and transmission in both pediatric and adult populations, flue vaccination coverage, and post-infectious respiratory complications. . The book's goal is to promote the restoration and maintenance of good health, disease prophylaxis, and improved patient management by integrating research into clinical work and findings on improving care. It offers a valuable asset for clinical specialists, researchers, and everyone engaged in healthcare.
Since 1959, the International Society of Arterial Chemoreception (ISAC) has organized in a variety of countries fifteen scientific meetings devoted to the mechanisms of peripheral arterial chemoreception and chemoreceptor reflexes. After the meeting held in Philadelphia with Sukhamay Lahiri as president, ISAC membership elected Lyon (CNRS, University Claude Bernard, France) as the site of the xv" ISAC Symposium. The Symposium was effectively held in Lyon from the 18th to the 22nd of November 2002 and Jean-Marc Pequignot was its president. The organizers were Jean-Marc Pequignot and Yvette Dalmaz Lyon (CNRS, University Claude Bernard, France) and the Scientific Committee was formed by John Carroll (University of Arkansas for Medical Sciences, USA), Constancio Gonzalez (University of Valladolid, Spain), Prem Kumar (University of Birmingham, U. K. ), Sukhamay Lahiri (University of Pennsylvania, Philadelphia, USA), Colin Nurse (McMaster University, Hamilton, Ontario, Canada), and Nanduri Prabhakar (Case Western University, Cleveland, Ohio, USA). The Symposium in Lyon intended to follow the path opened in Philadelphia gathering people working at the interface of cellular and molecular biology with researchers in the more classical topics of chemoreception pathways and reflexes. The aim was to join experts with different perspectives. Along these lines, some participants are engaged in the exploration of the intimate mechanisms of oxygen sensing and cellular responses, with their work centered in a great number of preparations covering a broad spectrum from bacteria, to chemoreceptor cells or to central nervous systems neurons.

This book provides readers with a timely update on this rapidly advancing area of investigation, presenting an invaluable resource for researchers in the field.
The discovery of adult neurogenesis and of stem cells in the adult brain has changed our view of the mature brain. With new neurons being produced lifelong, brain development does not seem to end and brain plasticity gains a whole different meaning, if the brain's malleability goes beyond synapses and neurites. But adult neurogenesis occurs in two privileged regions only, the hippocampus and the olfactory system. Since the mid-1990s, the field of adult neurogenesis research has literally exploded. The second edition became necessary, after hundreds of new reports had been published. Most progress has been made with respect to the question of the functional relevance of the new neurons and their contribution to learning and memory. The book has become a reference resource for everybody interested in adult neurogenesis and stem cell biology of the adult brain. It begins with the historical background and describes in detail adult neurogenesis in the hippocampus as well as the subventricular zone and olfactory bulb. Regulatory mechanisms are discussed in great detail. The subject of neurogenesis outside the "canonical" neurogenic regions of rodents and primates is discussed and an entire chapter is dedicated to adult neurogenesis in different species. The book concludes with a chapter on the provocative hypotheses that link failing adult neurogenesis with diseases such as temporal lobe epilepsy, major depression, schizophrenia, brain tumors, and dementias.
The scientific advances in the physiology and pathophysiology of adipose tissue over the last two decades have been considerable. Today, the cellular and molecular mechanisms of adipogenesis are well known. In addition, adipose tissue is now recognized as a real endocrine organ that produces hormones such as the leptin acting to regulate food intake and energy balance in the central nervous system, a finding that has completely revolutionized the paradigm of energy homeostasis. Other adipokines have now been described and these molecules are taking on increasing importance in physiology and pathophysiology. Moreover, numerous works have shown that in obesity, but also in cases of lipodystophy, adipose tissue was the site of a local low-grade inflammation that involves immune cells such as macrophages and certain populations of lymphocytes. This new information is an important step in the pathophysiology of both obesity and related metabolic and cardiovascular complications. Finally, it is a unique and original work focusing on adipose tissue, covering biology and pathology by investigating aspects of molecular and cellular biology, general, metabolic, genetic and genomic biochemistry.

Controversies in Exercise Science introduces a series of selected unresolved issues in the field of human exercise science. The common thread to all of these topics is that, in their ultimate resolution, they offer promise of insights into the essential principles of physiological systems and how these respond to the stresses of exercise. Each case study includes an examination of research surrounding each issue; the innovative aspect, however, will be that each of these controversies will be presented in the context of an historical and/or philosophical perspective. These chapter include topics related to basic exercise physiology, sports, physical activity, and exercise health. Underlying each of these debates lie clues which may offer insights into the basic nature of living beings. Aimed at both academics and practitioners in the fields of exercise science, biology, and related sports science disciplines, Controversies in Exercise Science provides arguments for both sides of several selected contemporary controversies in the field of exercise science and, while no ultimate resolution will be provided, the goal is, rather, to offer the reader sufficient "raw material" on which he or she might make their own judgement on the matters presented.

Nutrition and Skeletal Muscle provides coverage of the evidence of dietary components that have proven beneficial for bettering adverse changes in skeletal muscle from disuse and aging. Skeletal muscle is the largest tissue in the body, providing elements of contraction and locomotion and acting as an important contributor to whole body protein and amino metabolism, glucose disposal and lipid metabolism. However, muscle loss, atrophy or weakness can occur when there are metabolic imbalances, disuse or aging. This book addresses the topic by providing insight and research from international leaders, making it the go-to reference for those in skeletal muscle physiology.
This book contains an extensive collection of critical reviews, from leading researchers in the field of regulated protein degradation.

It offers researchers and clinicians expert analyses of nephro-endocrine research and translation into the treatment of diseases such as anemia, chronic kidney disease (CKD), rickets, osteoporosis, and hypoparathyroidism. Changes to this edition include new chapters focused on hypercalcemia/hypocalcemia and the interaction of dialysis, chronic renal disease, and endocrine diseases. All chapters have been updated to include more preclinical data and more tables and schema that help translate this data into clinical recommendations. The section on hormones and renal insufficiency discusses insulin/diabetes, growth hormone, sex steroids, thyroid hormone, acid-base disturbances, and pregnancy.
The Auditory System in Sleep, Second Edition presents a view of a sensory system working in a different state, that of the sleeping brain. This updated edition contains new chapters on topics such as implanted deaf patients and sleep and tinnitus treatments. It is written for basic auditory system and sleep researchers, as well as practitioners and clinicians in the Auditory/Sensory Neurosciences and Sleep Medicine. As the auditory system is always "open", thus receiving information from the environment and the body itself (conscious and unconscious data), the incoming sensory information may alter sleep and waking physiology, and conversely, the sleeping brain. This book draws information from evoked potentials, fMRI, PET, SPECT, lesions, and more.
This book discusses the maximal power and capacity of the three major biochemical pathways - aerobic (oxygen consumption), anaerobic lactic (muscle lactate accumulation in absence of oxygen consumption), and anaerobic alactic (phosphocreatine hydrolysis) metabolism - as well as the factors that limit them. It also discusses the metabolic and cardio-pulmonary mechanisms of the dynamic response to exercise. The way and extent to which the power and capacity of the three major energy metabolisms are affected under a number of different conditions, such as training, hypoxia and microgravity, are also described. |
