Preconditioning to lowered oxygen levels (hypoxia) may occur when an animal is subjected to non-lethal levels of hypoxia and then returned to normoxic conditions. During a subsequent exposure to hypoxia, the pre-exposed animals may exhibit increased tolerance compared to naive animals. I have demonstrated, by analysis of critical PO2's (Pcrit), that zebrafish embryos can be preconditioned to hypoxia. Preconditioned embryos display a lower Pcrit than controls, indicating a heightened ability to endure hypoxic conditions. The role of the hypoxia inducible factor-1 (HIF-1) in promoting hypoxic preconditioning was examined. To determine the role of HIF-1 in preconditioning, embryos deficient in HIF-1alpha (using antisense oligonucleotide morpholinos) were assessed under hypoxic conditions. No significant difference between preconditioning capacities of control- and HIF-1alpha deficient embryos was observed. In addition to assessing Pcrit, a suite of hypoxia responsive genes were analysed by real time PCR. IGFBP-2 showed a significant decrease in expression in the HIF-1alpha deficient embryos, and EPO showed a significant increase in HIF-1alpha deficient embryos. All other genes examined showed no significant change between treated and control embryos.

The thoroughly updated Eighth Edition of this classic three-volume work provides the most comprehensive, current, and authoritative information on diseases of the kidney and urinary tract. This clinically oriented reference focuses on diagnosis and treatment of specific diseases, disorders, and complications and incorporates the basic science practicing physicians need to evaluate and manage the disease process. Each of the fourteen sections is written by internationally renowned contributors and provides coverage comparable to a complete book. The first two sections review renal basic science and describe current diagnostic tools. The remaining twelve sections cover various types of diseases, including hypertension, urological problems, and urinary tract concerns. Each disease-oriented section begins with an up-to-date review of pathophysiology and then focuses on specific diseases. This edition has new lead authors for more than 25 chapters, and separate chapters on heart disease and the kidney, liver disease and the kidney, and the nephrotic syndrome.

This book will deal with heat shock proteins and more generally with stress-related inducible gene expression as a pleiotropic adaptive response to stress. It presents a textbook-like overview of the field not only to heat shock experts, but to physiologists, pharmacologists, physicians, neuropsychologists and others as well. It is intended to be a state-of-the-art and perspective book rather than an up-to-date presentation of recent data. It should provide a basis for new experimental approaches to fields at the edge of the classical heat shock field. Drugs, UV irradiation and environmental toxics will considered as important modulators of the stress response. Radical scavengers such as superoxide dismutases and inducible regulatory proteins of metallic ion status such as ferritin as well as immunophilins and protein disulfide isomerases will be considered within the frame of stress proteins. The potential practical applications of heat shock proteins in toxicology and medicine for the diagnosis, prognosis and eventually therapy of clinical conditions associated with an increased oxidative burden will be outlined. The role of heat shock proteins in the modulation of immune responses will also be included. The book considers heat shock from a broad perspective including fields for which heat-shock may become of importance in the very near future such as cellular responses to environmental stresses and complex stress responses under specific conditions. It was also felt timely to incorporate a whole section on medical and technological applications of stress proteins.

The ability of cells to sense and respond to changes in oxygenation underlies a multitude of developmental, physiological, and pathological processes. This volume provides a comprehensive compendium of experimental approaches to the study of oxygen sensing in 48 chapters that are written by leaders in their fields.

Hypoxia remains a constant threat throughout life. It is for this reason that the International Hypoxia Society strives to maintain a near quarter century tradition of presenting a stimulating blend of clinical and basic science discussions. International experts from many fields have focused on the state-of-the-art discoveries in normal and pathophysiological responses to hypoxia. Topics in this volume include gene-environment interactions, a theme developed in both a clinical context regarding exercise and hypoxia, as well as in native populations living in high altitudes. Furthermore, experts in the field have combined topics such as skeletal muscle angiogenesis and hypoxia, high altitude pulmonary edema, new insights into the biology of the erythropoietin receptor, and the latest advances in cardiorespiratory control in hypoxia. This volume explores the fields of anatomy, cardiology, biological transport, and biomedical engineering among many others.

A comprehensive and authoritative survey of recent findings, ideas, and hypotheses about the causes and treatment of diabetic nephropathy. The authors cover both the basic pathogenic mechanisms of the disease, as well as many of its clinical aspects of identification, management, and new therapeutic approaches. Highlights include an entire section devoted to novel approaches to studying diabetic nephropathy with the most advanced molecular techniques, and complete descriptions of the most up-to-date views on the diagnosis and treatment of the disease. The Diabetic Kidney offers both researchers and practicing clinicians a clear understanding of the of the progress that has been made regarding the pathogenesis of diabetic nephropathy and of the therapeutic interventions needed to prevent its development or treat it.

This book discusses the current research concepts and the emerging technologies in the field of stem cells and tissue engineering. It is the first authoritative reference documenting all the ways that plastic surgical practice and regenerative medicine science overlap or provide a road map for the future of both specialties. The Editors have provided a valuable service by gathering in one place the leading voices in these two fields in clear and concise manner. Divided into five parts, the book opens with a description of the elements of regenerative medicine including definitions, basic principles of soft and bone tissue regeneration, biomaterials and scaffolds. Current research concepts are explored in the second part of this book, for example mechanotransduction and the utility of extracellular vesicles. In the third part, the editors present the emerging technologies and highlight the novel perspectives on bionic reconstruction and biomimetics in surgery and regenerative medicine. Part four deals with translational aspects including practical information on moving scientific findings from bench to bedside. The final part then describes in detail applications in clinical plastic surgery. Written by leading experts this book is an invaluable resource for researchers, students, beginners and experienced clinicians in a range of specialties. "In your hands is a comprehensive encyclopedia of two rapidly converging fields. Drs Duscher and Shiffman have done an outstanding job of highlighting the interdependent relationship between plastic surgery and regenerative medicine. Ultimately, this is to the benefit of both fields." - Geoffrey C. Gurtner, MD, FACS Johnson and Johnson Distinguished Professor of Surgery Professor (by courtesy) of Bioengineering and Materials Science Inaugural Vice Chairman of Surgery for Innovation Stanford University School of Medicine
