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.

Book excerpt: National bestselling author Juliet Marillier revisits the classic fairy tale of Beauty and the Beast in this “engaging Gaelic fantasy romance staring two fascinating reluctant souls”(Genre Go Round Reviews). Whistling Tor is a place of secrets, a mysterious, wooded hill housing the crumbling fortress belonging to Anluan—a chieftain whose name is spoken throughout the region in tones of revulsion and bitterness. A curse lies over Anluan’s family and his people, and the woods themselves hold a perilous force whose every whisper threatens doom. Then the young scribe Caitrin appears in Anluan’s garden, admiring the rare plant known as heart’s blood. Retained to sort through entangled family documents, Caitrin brings about unexpected changes in the household, casting a hopeful light against the despairing shadows. But even as Caitrin brings solace to Anluan, and the promise of something more between them, he remains in thrall to the darkness surrounding Whistling Tor. To free Anluan’s burdened soul, Caitrin must unravel the web of sorcery woven by his ancestors before it claims his life—and their love...

Available in PDF, EPUB and Kindle. Book excerpt: Although cardiac output is measured as the flow of blood from the left ventricle into the aorta, the system that controls cardiac output includes many other components besides the heart itself. The heart’s rate of output cannot exceed the rate of venous return to it, and therefore, the factors governing venous return are primarily responsible for control of output from the heart. Venous return is affected by its pressure gradient and resistance to flow throughout the vascular system. The pressure gradient for venous return is a function of several factors including the blood volume flowing through the system, the unstressed vascular volume of the circulatory system, its capacitance, mean systemic pressure, and right atrial pressure. Resistance to venous return is the sum of total vascular resistance from the aortic valve to the right atrium. The sympathetic nervous system and vasoactive circulating hormones affect short-term resistance, whereas local tissue blood flow autoregulatory mechanisms are the dominant determinants of long-term resistance to venous return. The strength of contraction of the heart responds to changes in atrial pressure driven by changes in venous return, with small changes in atrial pressure eliciting large changes in strength of contraction, as described by the Frank–Starling mechanism. In addition, the autonomic nervous system input to the heart alters myocardial pumping ability in response to cardiovascular challenges. The function of the cardiovascular system is strongly affected by the operation of the renal sodium excretion–body fluid volume–arterial pressure negative feedback system that maintains arterial blood pressure at a controlled value over long periods. The intent of this volume is to integrate the basic knowledge of these cardiovascular system components into an understanding of cardiac output regulation.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Arterial hypertension, coronary heart disease and heart fail ure are the commonest cardiovascular conditions to present in clinical practice. Over the past few years it has become in creasingly clear that they are closely and causally interrelated and that their relationship can have a significant bearing on prognosis. Epidemiological studies have shown that arterial hypertension is one of the most important risk factors for de veloping heart failure. Only one in four patients with hyper tension is adequately managed, and in 50% of cases, the hypertension has not been recognised or treated. Patients with pre-existing hypertension who go on to suffer an acute myocardial infarction have usually not previously had typi cal angina symptoms, the infarct territory is larger, life threatening arrhythmias are commoner and hence in-hospi tal mortality and long-term prognosis are markedly worse. The presence of raised blood pressure in the post-infarct phase doubles the risk of manifest heart failure. The close relationship between hypertension, coronary heart disease and heart failure makes the choice of therapeu tic strategy particularly important. Agents and classes of agents that have prognostic value in all three conditions should be considered first, as synergy might result in addi tional benefits. In such patients, this sort of therapeutic deci sion-making might have further advantages. The use of these agents may prevent complications which are not yet clinically obvious (such as heart failure).

Available in PDF, EPUB and Kindle. Book excerpt: A generation past, the western realms were embroiled in endless war. Then the Destroyer came. From the blood and ashes he left behind, a tenuous alliance rose between the barbarian riders of Parsathe and the walled kingdoms of the south. That alliance is all that stands against the return of an ancient evil—until the barbarian king and queen are slain in an act of bloody betrayal. Though forbidden by the alliance council to kill the corrupt king responsible for his parents’ murders, Maddek vows to avenge them, even if it costs him the Parsathean crown. But when he learns it was the king’s daughter who lured his parents to their deaths, the barbarian warrior is determined to make her pay. Yet the woman Maddek captures is not what he expected. Though the last in a line of legendary warrior-queens, Yvenne is small and weak, and the sharpest weapons she wields are her mind and her tongue. Even more surprising is the marriage she proposes to unite them in their goals and to claim their thrones—because her desire for vengeance against her father burns even hotter than his own…

Available in PDF, EPUB and Kindle. Book excerpt: If the pulsations of the arteries fan and refrigerate the several parts of the body as the lungs do the heart, how comes it, as is commonly said, that the arteries carry the vital blood into the different parts, abundantly charged with vital spirits, which cherish the heat of these parts, sustain them when asleep, and recruit them when exhausted? and how should it happen that, if you tie the arteries, immediately the parts not only become torpid, and frigid, and look pale, but at length cease even to be nourished?-from the IntroductionThis seminal work of medical literature, first published in 1628, spells out in clear, lucid language how the human heart pumps blood around the body via its own exclusive circulatory route. What seems like an obvious concept to us today was in fact quite revolutionary at the time: Harvey's defiance of the medical "common knowledge" of his time laid the groundwork for all modern investigations of the circulatory system, and may be the most momentous discovery of 17th-century medicine.This important volume also includes a series of letters from Harvey to his medical colleagues in which he defends his then-astonishing theories, plus Harvey's "The Anatomy of Thomas Parr," a fascinating 1635 report on the dissection of the corpse of "a poor farmer of extremely advanced age."OF INTEREST TO: readers of scientific history, medical studentsBritish naturalist, anatomist, and doctor WILLIAM HARVEY (1578-1657) was educated at Cambridge, Canterbury, and Padua, and became a Fellow of the Royal College of Physicians in 1607. He served as court physician to both King James I and King Charles I.
