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
Hypertension is common in patients with kidney disease for a number of reasons, including retention, inappropriate action by the renin-angiotensin system, and overactivity of the sympathetic nervous system. Of all causes of hypertension, renal artery stenosis (narrowing) has attracted considerable attention, because it was once thought to be a rare cause of hypertension, but is now known to be the most common cause of secondary hypertension. In The Kidney and Hypertension, George Bakris and a host of international contributors examine all aspects of hypertension in the renal patient. A reference book covering specific and common topics in the area of kidney disease and hypertension, it is an essential guide to the effective management of the renovascular patient. It covers everything from how to properly measure blood pressure to the assessment and treatment of elevated blood pressure in high-risk groups such as dialysis patients and pregnant women. Kidney and Hypertension also thoroughly discusses reducing cardiovascular risk in people with kidney disease due to its role as a leading cause of death among kidney patients. Additionally, there is a chapter on diabetes and its role as a common cause of kidney failure. As an introduction to basic concepts in the treatment of hypertension, Dr. Bakris's book will serve as an excellent reference to nephrologists, cardiologists, and cardiovascular surgeons in their efforts to reduce the risks of advanced kidney disease and cardiovascular disease.

Book Description
Literally thousands of papers have been published on nitric oxide over the past ten years. But there is no single monograph available that has previously attempted to summarize the important features of the roles of nitric oxide in inflammation. The voluminous literature regarding the incredible range of chemical and biological effects of nitric oxide and reactive nitrogen oxide species, RNOS, may present a tangle of confusing information to the researcher. This volume brings together experts from nitric oxide and inflammation research and presents a concise up-to-date overview as well as future aspects of this rapidly growing field.

Book Description
Nitroglycerin and other organic nitrates have been used for over a century in the treatment of angina pectoris. Millions of patients, throughout the world, have placed nitroglycerin tablets under the tongue and have experienced rapid and dramatic relief from the chest pain that frequently occurs as a manifestation of disease of the coronary arteries. The empirical observation of the safe use of nitrates for tile alleviation of the symptoms of angina have led to their widespread medical acceptance. The use of organic nitrates preceded any knowledge of their mechanism of action or their ultimate metabolic fate. Thus, more simply stated, although sub lingual nitrates helped the patients, little was known concerning what these drugs do to the body or what the body does to the drugs. A substantial number of investigators have focused on these questions especially during the last two decades. We now have considerably more insight into the pathways of degradation of organic nitrates and the relationship of the metabolic processes to the biological action of these agents. Similarly, considerable effort has been expended in understanding the mechanism of action of these agents directly on vascular smooth muscle and on cardiac work and performance. Finally, there is a more substantive understanding of the physiology of the coronary circulation as well as the" pathophysiologic manifestations of myocardial disease.

Book Description
The present book contains the Proceedings of a two day Symposium on Uremic Toxins organized at the University of Ghent in Belgium. A series of guest lectures, free communications and posters have been presented. An international audience of 163 scientists from 16 nationalities listened to and discussed extensively a spectrum of topics brought forward by colleagues and researchers who worked for many years in the field of Uremic Toxins. There is a striking contrast between all the new dialysis strategies available in the work to "clean" the uremic patients and the almost non-progression of our knowledge on uremic toxins in the past decade. In this sense the symposium was felt by all participants as a new start for the research in the biochemical field of the definition of uremia. If the present volume would stimulate new work in this field in order to define uremia, or identify the uremic toxins, the purpose of the organizers would be maximally fulfilled.

Book Description
Extending from the outpatient management of cardiovascular and kidney disease, to hospital-based decision making in patients with cardio-renal disease and complex interfaces such as hemodialysis in patients with ventricular assist device support, this book serves as a single reference point for cardiology and nephrology clinicians and researchers dealing with the significant overlap areas between these two specialties. Chapters cover the physiology, biomarkers, therapeutic agents and full spectrum of these comorbidities and feature separate sections on cardiovascular and CKD evaluations, stratification of kidney transplant patients, lipid management in CKD, interventional strategies and hypertension. Leaders in cardiology, nephrology, hypertension and lipidology bring together the latest evidence with their collective clinical experience into this invaluable resource.This textbook is an essential resource for physicians and allied professionals practicing cardiology, nephrology, students and physician trainees, to deepen their understanding of this crucial field.
