Book Description
A comprehensive reference book on basic and clinical aspects Endothelin is a 21-amino acid peptide that exerts uniquely potent and long-lasting effects on the kidney, including regulation of water and electrolyte excretion, blood pressure, cell growth, inflammation and fibrosis. During the past 10 years, the field has evolved rapidly; we are now uncovering the potential importance of endothelin receptor antagonists (ERAs) in the treatment of kidney disease. This book reviews experimental concepts, preclinical studies and clinical data which form the basis of our current understanding of the association between endothelin and kidney disease. Acclaimed experts in pharmacology, molecular biology, physiology, cardiovascular medicine, and nephrology have contributed timely reviews dealing with renal pharmacology and physiology of endothelin, the role of endothelin in renal disease development and ERAs in preclinical studies, and the current state of clinical development of ERA therapy in renal medicine. The publication at hand will be a valuable reference source for nephrologists, internists and other healthcare professionals, renal physiologists and molecular biologists, post-doctoral researchers and students in the life sciences, as well as for scientists and decision makers in drug research and development.

Book Description
The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of α1-adrenoceptors and increase renin secretion rate by activation of β1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Activation of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

Book Description
Vitamin D deficiency, circulating levels lower than 15 ng/ml, is an epidemic disease worldwide with more than a billion people suffering of it in the beginning of the 21-century. Besides its impact on mineral and bone metabolism, these low vitamin D levels are also associated with a diversity of non-skeletal complications, among them cardiovascular disease, diabetes mellitus, multiple sclerosis, cancer, tuberculosis, and immune system dysfunction. Chronic Kidney Disease is also a very common disease, affecting more than 10% of the world population, ranging from stage 1 to stage 5 before dialysis. Approximately 1% of the population in industrialized countries is affected by end-stage renal disease (ESRD), needing a renal replacement therapy either hemodialysis or peritoneal dialysis, and ultimately by renal transplantation. Those CKD patients are more susceptible to exhibit reduced vitamin D stocks. Consequently, more than eighty percent of CKD patients have either insufficient or deficient vitamin D levels for multiple reasons.

Book Description
In the past decade there has been a major sea change in the way disease is diagnosed and investigated due to the advent of high throughput technologies, such as microarrays, lab on a chip, proteomics, genomics, lipomics, metabolomics etc. These advances have enabled the discovery of new and novel markers of disease relating to autoimmune disorders, cancers, endocrine diseases, genetic disorders, sensory damage, intestinal diseases etc. In many instances these developments have gone hand in hand with the discovery of biomarkers elucidated via traditional or conventional methods, such as histopathology or clinical biochemistry. Together with microprocessor-based data analysis, advanced statistics and bioinformatics these markers have been used to identify individuals with active disease or pathology as well as those who are refractory or have distinguishing pathologies. New analytical methods that have been used to identify markers of disease and is suggested that there may be as many as 40 different platforms. Unfortunately techniques and methods have not been readily transferable to other disease states and sometimes diagnosis still relies on single analytes rather than a cohort of markers. There is thus a demand for a comprehensive and focused evidenced-based text and scientific literature that addresses these issues. Hence the formulation of Biomarkers in Disease. The series covers a wide number of areas including for example, nutrition, cancer, endocrinology, cardiology, addictions, immunology, birth defects, genetics, and so on. The chapters are written by national or international experts and specialists.

Book Description
The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Book Description
Translational medicine underpins vascular medicine. It is fundamental to understanding how we treat patients with vascular disease and more importantly, how to prevent it. It is the rationale for drug design and production. Vascular medicine and translational medicine will take over and become the main reason for referring patients to hospital. Therefore, hospital-based clinicians working with basic scientists need to know about translational medicine, which educates and informs them about vascular medicine and how management should be based. This book is a primer for translational vascular medicine and discusses the evolving and exciting areas of basic science applied to vascular medicine. The book is based on the third vascular biology conference held at The Royal College of Physicians in 2008. It provides a large amount of new basic and clinical information and the contributors are world leaders.
