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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: While it has long been understood that the circulation of discourse, bodies, artifacts, and ideas plays an important constitutive force in our cultures and communities, circulation, as a concept and a phenomenon, has been underexamined in studies of rhetoric and writing. In an effort to give circulation its rhetorical due, Circulation, Writing, and Rhetoric introduces a wide range of studies that foreground circulation in both theory and practice. Contributors to the volume specifically explore the connections between circulation and public rhetorics, urban studies, feminist rhetorics, digital communication, new materialism, and digital research. Circulation is a cultural-rhetorical process that impacts various ecologies, communities, and subjectivities in an ever-increasing globally networked environment. As made evident in this collection, circulation occurs in all forms of discursive production, from academic arguments to neoliberal policies to graffiti to tweets and bitcoins. Even in the case of tombstones, borrowed text achieves only partial stability before it is recirculated and transformed again. This communicative process is even more evident in the digital realm, the underlying infrastructures of which we have yet to fully understand. As public spaces become more and more saturated with circulating texts and images and as networked relations come to the center of rhetorical focus, Circulation, Writing, and Rhetoric will be a vital interdisciplinary resource for approaching the contemporary dynamics of rhetoric and writing.

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.

Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Available in PDF, EPUB and Kindle. Book excerpt: In this vivid ethnography, Jessaca B. Leinaweaver explores “child circulation,” informal arrangements in which indigenous Andean children are sent by their parents to live in other households. At first glance, child circulation appears tantamount to child abandonment. When seen in that light, the practice is a violation of international norms regarding children’s rights, guidelines that the Peruvian state relies on in regulating legal adoptions. Leinaweaver demonstrates that such an understanding of the practice is simplistic and misleading. Her in-depth ethnographic analysis reveals child circulation to be a meaningful, pragmatic social practice for poor and indigenous Peruvians, a flexible system of kinship that has likely been part of Andean lives for centuries. Child circulation may be initiated because parents cannot care for their children, because a childless elder wants company, or because it gives a young person the opportunity to gain needed skills. Leinaweaver provides insight into the emotional and material factors that bring together and separate indigenous Andean families in the highland city of Ayacucho. She describes how child circulation is intimately linked to survival in the city, which has had to withstand colonialism, economic isolation, and the devastating civil war unleashed by the Shining Path. Leinaweaver examines the practice from the perspective of parents who send their children to live in other households, the adults who receive them, and the children themselves. She relates child circulation to international laws and norms regarding children’s rights, adoptions, and orphans, and to Peru’s history of racial conflict and violence. Given that history, Leinaweaver maintains that it is not surprising that child circulation, a practice associated with Peru’s impoverished indigenous community, is alternately ignored, tolerated, or condemned by the state.

This book was released on 2012-04-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because nearly all aspects of culture depend on the movement of bodies, objects, and ideas, mobility has been a primary topic during the past forty years of archaeological research on small-scale societies. Most studies have concentrated either on local moves related to subsistence within geographically bounded communities or on migrations between regions resulting from pan-regional social and environmental changes. Gregson Schachner, however, contends that a critical aspect of mobility is the transfer of people, goods, and information within regions. This type of movement, which geographers term "population circulation," is vitally important in defining how both regional social systems and local communities are constituted, maintained, and--most important--changed. Schachner analyzes a population shift in the Zuni region of west-central New Mexico during the thirteenth century AD that led to the inception of major demographic changes, the founding of numerous settlements in frontier zones, and the initiation of radical transformations of community organization. Schachner argues that intraregional population circulation played a vital role in shaping social transformation in the region and that many notable changes during this period arose directly out of peoples' attempts to create new social mechanisms for coping with frequent and geographically extensive residential mobility. By examining multiple aspects of population circulation and comparing areas that were newly settled in the thirteenth century to some that had been continuously occupied for hundreds of years, Schachner illustrates the role of population circulation in the formation of social groups and the creation of contexts conducive to social change.

Available in PDF, EPUB and Kindle. Book excerpt: Here is the first single-volume work to analyze in a comprehensive manner the mechanisms by which the human cardiovascular system adjusts to physical stresses such as exercise, heat, upright posture, and hypoxia. Emphasizing the regulation of regional blood flow and blood volume, the work delineates the unique character of the human cardiovascular system and the regulatory problems it faces. It represents a timely response to the growing interest in cardiovascular health, exercise, and physical conditioning. In describing the basic mechanisms of vasomotor control, the author focuses on the interaction between the arterial and venous systems. He indicates how control of regional circulations interacts with control of venous volume and cardiac performance, showing how vasomotor and venomotor regulation serves the entire organism. This treatment redresses an imbalance in contemporary teaching of cardiovascular physiology which has focused more on the heart than on the vasculature. The book utilizes graphics imaginatively throughout to clarify concepts in a fresh and effective way. Features: * Analytical, quantitative, and problem oriented * Uniquely comprehensive; coverage extends from small blood vessel functioning to the entire system * Imaginatively illustrated, with exceptionally clear graphics that explain basic principles and controversial ideas * Original, new ideas on how peripheral circulation influences heart performance * Probes the upper limits of human cardiovascular function, their causes and how they change
