Download or read book Chronomics and Continuous Ambulatory Blood Pressure Monitoring written by Kuniaki Otsuka and published by Springer. This book was released on 2016-03-05 with total page 934 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating volume applies the concept of chronomics to the medical treatment of hypertension. It starts with the recent updates on chronomics, the analytic techniques, and their application to community-based assessments. The authors advocate the use of 7-day/24-h records of blood pressure, which is effective for finding masked hypertension, masked morning surge, and other rhythm abnormalities. Most organisms, from cyanobacteria to mammals, are known to use the circadian mechanism. However, our body systems also demonstrate circaseptan (roughly weekly), circannual (roughly yearly), and even longer rhythms. Chronomics monitors the physiological data and then analyzes the superimposed rhythms, isolating the cycles mathematically to determine how organisms and their environment interact. It is the study of interactions among time structures (chronomes) in and around us.

Download or read book From Molecule to Men written by M. Zehender and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: From molecule to man: Medical research has indeed taken this direction, and major improvements of our understanding of the pathophysiology and epidemiology of disease have been achieved. The molecular basis of the congenital cardiovascular disorders has been extended from relatively few congenital malformations into everyday illnesses such as diabetes mellitus, hyperlipoproteinaemea, and arterial hypertension. The monogenic and, more difficult, polygenic basis for a vast majority of cardiovascular disorders are being defined more precisely from year to year. This book gives an overview of what has been achieved so far and defines the current position.

Download or read book Blood Pressure Monitoring in Cardiovascular Medicine and Therapeutics written by William B. White and published by Springer Science & Business Media. This book was released on 2000-11-01 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood Pressure Monitoring in Cardiovascular Medicine and Therapeutics provides information that will be especially useful to all who care for hyperten sive patients. The various chapters provide a full account of the mounting sci entific evidence that blood pressure recordings need to be obtained for proper diagnosis, prognosis, and therapy for these patients. The contributors are each directly involved in clinical studies ofhome and ambulatory blood pressure moni toring, as well as of the relationship of circadian variations in heart rate and blood pressure to cardiovascular events. As a longtime observer of the multiple facets of clinical hypertension, I have been greatly impressed with the rapid advances in this area over the last two decades. Out-of-office blood pressure monitoring has grown from a curi osity to a necessity. In order to improve the currently inadequate control of hypertension throughout the world, such monitoring should become routine in the diagnosis and treatment of every patient. The evidence for the role of out-of-office monitoring that is so well described in Blood Pressure Monitoring in Cardiovascular Medicine and Therapeutics should serve as a stimulus for the more widespread adoption of the procedure. Once this is understood, the constraints on the broader clinical use of ambulatory monitoring that now exist in the United States will be lifted as the value of such information becomes more generally recognized. In the meantime, self-recorded home measurements should be more widely utilized.

Download or read book Pediatric Hypertension written by Ronald J. Portman and published by Springer Science & Business Media. This book was released on 2004-06-12 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of hypertension in children and adolescents is becoming incre- ingly recognized by physicians and scientists in the 21st century. However, in contrast to the attention that hypertension has received in the adult population for the past three decades since the first Joint National Committee (JNC) report, research and clinical knowledge that involves hypertension in children is still very much in its own childhood. Pediatric Hypertension, edited by Drs. Portman, Sorof, and Ingelfinger, is undoubtedly the most up-to-date and clinically relevant contribution to the field of hypertension in children available because it brings together the numerous pathophysiologic, diagnostic, and therapeutic advances in the evaluation of high blood pressure in infants, children, and adolescents. The editors have carefully organized their volume into sections that cover blood pressure regulation in infants and children, blood pressure measurement issues, pat- physiology and clinical assessment for essential and secondary forms of hypertension during childhood, and nonpharmacologic and pharmacologic approaches to the tre- ment of hypertension in children.

Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.
Download or read book Regulation of Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
Download or read book Somatic and Autonomic Regulation in Sleep written by Elio Lugaresi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the contributions to a course entitled "Sleep and its Pathology", which was organized by the Advanced School of the Italian Neuro science Society at the "Alessandro Volta" Center of Scientific Culture (Villa Olmo, Como, Italy, May 9-10,1996). The course was aimed at informing the medical audience about recent deve lopments in the field with particular regard to the work of the sleep laboratories of the University of Bologna. The first part of this book presents experimental results dealing with the bio chemical specificity of hypothalamic sleep mechanisms, cerebral metabolism during sleep and the sleep-dependent systemic cardiovascular adjustments in relation to blood perfusion and thermal homeostasis of the brain. The second part covers pathophysiological aspects of human sleep, namely the circadian rhythm of body core temperature in neurodegenerative diseases, the descriptive epidemiology of excessive daytime sleepiness, the disorders of breathing and motor control in sleep and the syndrome of nocturnal frontal lobe epilepsy. The Editors hope that the book may be useful not only to specifically interested rea ders, but also to general practitioners. The Editors wish to express special thanks to Professor Eugenio E. Muller for his suggestion to collect the lectures in book-form. The Editors thank the authors for their contributions to the course and to this publication and express their appreciation to Springer-Verlag for helping make this monography possible.

Download or read book The Pineal Gland and Cancer written by C. Bartsch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 979 pages. Available in PDF, EPUB and Kindle. Book excerpt: The link between the pineal gland and cancer is a rapidly emerging research field due to promising experimental and clinical trials with melatonin. The pineal gland acts as a transducer of environmental light to regulate rhythmic processes, including reproductive function in seasonally breeding animals and the entrainment of circadian rhythms, such as the sleep-wake cycle, in man. This book elucidates the physiological significance of the pineal gland and surveys phenomena and mechanisms of pineal - tumor interaction at the neuroendocrine, neuroimmune, neural, and molecular levels. Yet unidentified low-molecular-weight pineal substances with tumor-inhibiting capacity, a possible involvement of melatonin in electromagnetic field effects on cancer, and the oncotherapeutic potential of melatonin are also addressed. The encouraging results should incite further research to elucidate the exact nature of the link between the pineal gland and cancer for the benefit of patients.
