Book Description
Hypertension remains the leading cause of cardiovascular morbidity and mortality in spite of current medical therapies. It has been estimated that 50% of Western civilization has hypertension and approximately 20% of patients have resistant hypertension. Renal denervation (RDN) is a minimally invasive, endovascular catheter based procedure using radiofrequency ablation aimed at treating resistant hypertension. Early studies show a high degree of effectiveness in renal denervation to treat hypertension. This book examines renal pathophysiology and the rationale for renal denervation, as well as possible long term benefits and risks of this new therapy. The myriad of devices involved in the evolution of this therapy are discussed and the book concludes with analyses of the cost effectiveness and future applications.

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
Sympathetic overactivity is associated with the development of hypertension. Renal denervation (RDN) prevents or delays hypertension in a variety of animal models, which laid the groundwork for the introduction of RDN as a clinical therapy in humans. In 2007, a novel, minimally invasive RDN ablation catheter was first trialled in hypertensive patients, with a 93% success rate of lowering blood pressure for at least three years post-RDN. However, a large scale, sham-controlled clinical trial (Symplicity HTN -3) failed to show reductions in BP greater than sham. The aim of this research topic was to evaluate the efficacy and safety of RDN, to explore the contribution of both afferent and efferent renal nerve activity to hypertension and non-hypertension disorders, and to stimulate future research to better understand the function of the renal nerves and the effects of RDN by highlighting gaps in knowledge.

Book Description
There is an enormous sense of excitement in the communities of cancer research and cancer care as we move into the middle third of the ?rst decade of the 21st century. For the ?rst time,there is a true sense of c- ?dence that the tools provided by the human genome project will enable cancer researchers to crack the code of genomic abnormalities that allow tumor cells to live within the body and provide highly speci?c, virtually non-toxic therapies for the eradication,or at least ?rm control of human cancers. There is also good reason to hope that these same lines of inquiry will yield better tests for screening, early detection, and prev- tion of progression beyond curability. While these developments provide a legitimate basis for much op- mism, many patients will continue to develop cancers and suffer from their debilitating effects, even as research moves ahead. For these in- viduals, it is imperative that the cancer ?eld make the best possible use of the tools available to provide present day cancer patients with the best chances for cure, effective palliation, or, at the very least, relief from symptoms caused by acute intercurrent complications of cancer. A modality that has emerged as a very useful approach to at least some of these goals is tumor ablation by the use of physical or physiochemical approaches.

Book Description
​Vascular management and care has become a truly multidisciplinary enterprise as the number of specialists involved in the treatment of patients with vascular diseases has steadily increased. While in the past, treatments were delivered by individual specialists, in the twenty-first century a team approach is without doubt the most effective strategy. In order to promote professional excellence in this dynamic and rapidly evolving field, a shared knowledge base and interdisciplinary standards need to be established. Pan Vascular Medicine, 2nd edition has been designed to offer such an interdisciplinary platform, providing vascular specialists with state-of-the art descriptive and procedural knowledge. Basic science, diagnostics, and therapy are all comprehensively covered. In a series of succinct, clearly written chapters, renowned specialists introduce and comment on the current international guidelines and present up-to-date reviews of all aspects of vascular care.

Book Description
In anticipation of the opening of the H. Lee Moffitt Cancer Center and Research lnstitut~ on the campus of the University of South Florida, an international symposium, "The First Annual H. Lee Moffitt Symposium on Cancer Biology and Therapeutics" was held in Tampa, Florida on January 20-22, 1986. In this first symposium we decided to present a broad-based series of topics dealing with the major issues in the field of cancer. These topics ranged from the biochemistry of the cancer cell to the design of antineoplastic agents, through tumor cell heterogeneity, treatment of ltuman neoplasms to immunological aspects of cancer biology and tr~atment. The speakers chosen represented individuals of international acclaim who are very active in the area of cancer research and treatment. The symposium brought together scien tists/physicians from six nations including Austria, Canada, France, Hungary, West Germany, and of course, the United States. The congeniality of the participants promoted the friendly exchange of knowledge which, it is hoped, will greatly hasten the time when successful management of human cancer will become routine. Future symposia in this series will be highly focused and will deal with a single facet of this vast field of cancer research and treatment. Joseph G. Cory, Editor Andor Szentivanyi, Editor University of South Florida, 1986 V ACKNOWLEDGMENTS This volume presents the Proceedings of the H. Lee Moffitt International Syn~osium on Cancer Biology and Therapeutics which was held in Tampa, Florida on January 20, 21, and 22, 1986.

Book Description
A growing number of people suffer from so-called resistant hypertension, that is to say, high blood pressure that does not respond to treatment. This disorder is of great current interest and importance for public health, being a common clinical problem faced by both primary care clinicians and specialists. Furthermore, as older age and obesity are among the strongest risk factors for uncontrolled hypertension, the incidence of resistant hypertension will likely increase as the population becomes more elderly and heavier. While the prognosis of resistant hypertension is unknown, cardiovascular risk is undoubtedly increased since patients often have a history of long-standing, severe hypertension complicated by multiple other cardiovascular risk factors. This volume, compiled by a panel of world-renowned experts, offers a comprehensive exploration of resistant hypertension, covering epidemiology, complex diagnostic aspects, and the therapeutic options currently available, with due attention to overall treatment strategies. New therapeutic agents and procedures, such as renal denervation and baroreceptor stimulation, are also described. In addition, the book addresses the economic aspects of resistant hypertension and the role of the different professional figures, from GPs to hypertension specialists, in dealing with it.

Book Description
It is well known that cardiovascular events occur more frequently in the morning as blood pressure (BP) levels have been shown to increase during the period from night to early morning. In recent years, clinical research using ambulatory blood pressure monitoring (ABPM) or home BP monitoring has clarified that morning BP and BP surge are more closely related to the cardiovascular risk than clinical BP. This practical manual from field leading expert, Dr. Kazuomi Kario, reviews recent evidence on morning and nocturnal hypertension and the IT technologies physicians can use to support patients in home monitoring BP. Guidance on management via antihypertensive drugs is also discussed and with the aim of promoting perfect 24 hour BP control.

Book Description
Since the discovery of blood pressure by Stephen Hales in 1733, scientific interest in blood pressure regulation, particularly in hypertensive population, has not lost its popularity. The importance of the interactive effects of blood pressure shifts in different clinical conditions is well understood. We know many contributing factors regulate the pressure of the blood within the arteries. However, crucial blood pressure control and the exact mechanisms involved are still under debate. The present book aims to cover blood pressure from its measurement to various factors of its control with valuable contributions from different authors, in the light of contemporary data, from bench to bed.
