This book was released on 2013-12-11 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavioral neuroscience of thirst and sodium appetite are research ventures that have expanded dramatically in recent years. Work done in the mid-1950s and early 1960s made it clear that drinking behavior could be affected by direct manipulations of the brain, especially by brain damage and by pharmacological treat ments. Since that. time experimental approaches have diversified and the research enterprise has attracted the interest of a broad international community of scientists. Many aspects of both thirst and sodium appetite are being studied. The most prominent of these are: 1) phylogenetic and ontogenetic aspects of the phenomena of drink ing behavior, 2) the mechanisms of a variety of dipsogenic and antidipsogenic treatments, both drugs and hormones, 3) the biological controls of drinking and their interaction with the regulation of blood volume and blood pressure, 4) the peripheral signals of drinking including the role of the baro- and volume-receptors, 5) the receptor systems within the brain and the neuroanatomical circuitry for thirst and sodium appetite, and 6) the possible roles of brain sodium and of the hormones of sodium conservation ln the arousal of sodium appetite. This acceleration of basic research activity has given in sights into the clinical disorders of thirst and salt appetite and has produced pharmacological agents of potential therapeutic use.
Download or read book Thirst and Sodium Appetite written by Sebastian Grossman and published by Elsevier. This book was released on 2012-12-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirst and Sodium Appetite: Physiological Basis describes the phenomenon of thirst and the mechanisms that define the need for water. Thirst and appetite has generated much study and research about the physiological, endocrinological, and pharmacological mechanisms that influence water intake. However, in this book, other concerns have been emphasized, such as the significance of brain mechanisms in the subject matter. This book, consisting of 11 chapters, starts with a basic description of thirst then to an analysis of basic physiological mechanisms that determine water intake. Another topic also discussed in this book is various experimental paradigms that resulted to the dual-depletion theory of thirst. The neuroanatomical, neuroendocrinological, and neuropharmacological brain mechanisms are covered in three chapters of this book. These brain mechanisms respond to different peripheral signals that stimulate the thirst. The final chapters are dedicated to sodium appetite. Although it has lesser literature than thirst has, there have been significant developments in the understanding of the role of sodium appetite in extracellular thirst. The last chapter reviews the questions that has kept investigators at bay and recommends direction of where future research may go.

Download or read book Sodium Hunger written by Jay Schulkin and published by Cambridge University Press. This book was released on 1991 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hunger for sodium has been used as a model system in which to study how the brain produces motivated behaviour. In this account of the field Jay Schulkin draws together information across a range of disciplines and topics, ranging from the ecology of salt ingestion to the sodium molecule and the action of various hormones. The phenomenon of sodium hunger was discovered by Curt Richter, the great American psychobiologist, over 50 years ago. Its study has been of interest for some time: to naturalists, psychologists, endocrinologists, physiologists and neuroscientists. This book offers a systematic account of the behaviour of the sodium hungry animal, the endocrine and physiological mechanisms that act to maintain sodium balance and then act on the brain to promote the search for and the ingestion of salt. Finally, the book provides a description of a neural network that orchestrates the behaviour of salt seeking and salt ingestion. Graduate students and research workers in psychology, physiology and neuroscience will find valuable information in this review.

Download or read book Thirst written by David J. Ramsay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: At one time or another, everyone has said "I am thirsty". Yet what causes this sensation of thirst? It is obvious that a certain quantity of fluid must be present for the body to function normally. How does a water deficit in the body then influence drinking habits? But supposing the physiological need is met, what about the psychological need or social need? Water is certainly the most necessary fluid; then why do we humans often prefer other beverages, even at great cost of effort or money or health? The subject of thirst and drinking behavior are uniquely discussed in this book. For the first time both the physiological and the psychological aspects of water and beverage consumption are examined in one volume. The many recent developments concerning how a lack of water is signalled physiologically and processed neurally to affect drinking behavior are critically surveyed. Prospects for understanding the cultural and sensory influences on beverage consumption are mapped out. The thirty-one chapters by authorities in the field were all mutually reviewed and revised in the light of precirculated comments and round-table discussions. Together they provide a complete picture of the current state of knowledge on what determines fluid consumption in human beings and animals.
Download or read book Enteroceptors written by B. Andersson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series of concise essays on Enteroceptors is designed to interest the gradu ate student and to stimulate research. Even before the advent of electrophysiological studies, classical physiological techniques had shown the essence of the role of many of the enteroceptors. Thus the monitoring influence of the cardiovascular mechanoreceptors on the heart and on the systemic vascular resistance, the role of the arterial chemoreceptors in hypoxia and the influence of the so-called Hering Breuer stretch receptors on breathing had all been documented. The pioneering work of ADRIAN, BRONK, ZOTTERMAN and others using electroneurographic methods gave a remarkable impetus to the study of the enteroceptors themselves. Nowhere is this better exemplificd than in the case of the afferent end organs of the heart, the respiratory tract and the abdominal and pelvic viscera. The remarkable development of our knowledge of the multiplicity of types of nerve endings from the thoracic and abdominal viscera acquired from electrophysiological studies has refocussed our attention on the histological details of the sites of such receptors. Once more research on the structural side has been accelerated by the question raised by evidence obtained from functional studies. This is well illustrated in the case of the carotid body, where the long cherished belief that the innervated epithelioid cells constitute the chemoreceptor complex is now under attack. The detailed consideration of the functional characteristics of each entero ceptor considered has not occupied our whole attention.

This book was released on 2005-06-18 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. This new report, the sixth in a series of reports presenting dietary reference values for the intakes of nutrients by Americans and Canadians, establishes nutrient recommendations on water, potassium, and salt for health maintenance and the reduction of chronic disease risk. Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate discusses in detail the role of water, potassium, salt, chloride, and sulfate in human physiology and health. The major findings in this book include the establishment of Adequate Intakes for total water (drinking water, beverages, and food), potassium, sodium, and chloride and the establishment of Tolerable Upper Intake levels for sodium and chloride. The book makes research recommendations for information needed to advance the understanding of human requirements for water and electrolytes, as well as adverse effects associated with the intake of excessive amounts of water, sodium, chloride, potassium, and sulfate. This book will be an invaluable reference for nutritionists, nutrition researchers, and food manufacturers.

Download or read book Biological and Behavioral Aspects of Salt Intake written by Morley Kare and published by Elsevier. This book was released on 2012-12-02 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological and Behavioral Aspects of Salt Intake presents the developmental, social, and anthropological aspects of salt intake. This book explores the existing knowledge of those factors that influence man's appetite for salt. Organized into five parts encompassing 28 chapters, this book starts with an overview of the pathological and physiological importance attached to levels of salt intake in health and in disease. This text then examines the scientific information concerning the nature of man's appetite for salt and the variations of that appetite as an expression of biological needs, behavioral patterns, differing environmental conditions, and normal or disturbed physiology. Other chapters examine the plasma renin activity, urinary sodium excretion, and taste responses of hypertensive and normotensive individuals. The final chapter explores the relations between taste, intake, preference, and hypertension. This book is a valuable resource for nutritionists, food scientists, and researchers interested in the planning of nutritional programs in public health or therapeutic regimens.

Download or read book Handbook of Nutrition Diet and Epigenetics written by Vinood B. Patel and published by Springer. This book was released on 2019-02-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume reference work addresses the fact that the well being of humankind is predicated not only on individuals receiving adequate nutrition but also on their genetic makeup. The work includes more than 100 chapters organized in the following major sections: Introduction and Overview; Epigenetics of Organs and Diseases in Relation to Diet and Nutrition; Detailed Processes in Epigenetics of Diet and Nutrition; Modulating Epigenetics with Diet and Nutrition; and Practical Techniques. While it is well known that genes may encode proteins responsible for structural and dynamic components, there is an increasing body of evidence to suggest that nutrition itself may alter the way in which genes are expressed via the process of epigenetics. This is where chemically imposed alteration in the DNA sequence occurs or where the functional expression of DNA is modulated. This may include changes in DNA methylation, non-coding RNA, chromatin, histone acetylation or methylation, and genomic imprinting. Knowledge regarding the number of dietary components that impact on epigenetic processes is increasing almost daily. Marshalling all the information on the complex relationships between diet, nutrition, and epigenetic processes is somewhat difficult due to the wide myriad of material. It is for this reason that the present work has been compiled.
Download or read book Caffeine in Food and Dietary Supplements written by Leslie A. Pray and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.
