Blood Passage is the electrifying second book in the Dark Caravan Cycle—a modern jinni fantasy-adventure trilogy from author Heather Demetrios, perfect for fans of Laini Taylor's Daughter of Smoke and Bone series and Leigh Bardugo's Grisha Trilogy. When Nalia arrives in Morocco to fulfill Malek's third and final wish, she's not expecting it to be easy. Especially because Malek isn't the only one after Solomon's sigil, an ancient magical ring that gives its wearer the power to control the entire jinn race. Nalia has also promised to take Raif, leader of the jinn revolution, to its remote location. Though Nalia is free of the bottle and shackles that once bound her to Malek as his slave, she's in more danger than ever before and no closer to rescuing her imprisoned brother. Meanwhile, Malek's past returns with a vengeance, and his well-manicured facade crumbles as he confronts the darkness within himself; and Raif must decide what's more important: his love for Nalia or his devotion to the cause of Arjinnan freedom.

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.

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.

This book describes the way in which the human brain is supplied with blood and how the brain uses this to provide nutrients, primarily oxygen and glucose, to brain cells in order to maintain healthy brain function. In particular, it focuses on the quantitative nature of blood flow and metabolism. The book covers models of blood flow and metabolism and how these can be measured using a variety of imaging and non-imaging techniques. It also examines how cerebral blood flow is controlled in response to a wide variety of challenges and how it changes with normal physiological variation and in response to a large number of pathological conditions, including stroke and dementia.As the first substantial book for over ten years in a fast-changing field, it highlights how the subject has progressed in the last couple of decades. It tackles the subject in a quantitative way, underlining its importance in both technical and clinical fields. Audiences with a technical or clinical background, especially researchers and postgraduate students in biomedical engineering or medicine, will find this a valuable read.

At the present time several techniques are available for studying quantitatively global and regional blood flow and metabolism of the human brain. How ever, many scientists working in the clinical and research field who would like to use these tools for their investigations may be less familiar with the indi cations and limitations of the individual methods. The rapid development of both modern imaging techniques and new tracers may have led to some con fusion in answering the question as to which method is appropriate to solve the diagnostic problem of an individuum with brain disease. Scepticism and ignorance as to the methods to be used as tools in differential diagnosis of brain disorders may have prevented their widespread introduction into clinical practice. Thus, the significance of circulatory and metabolic parameters involved in the majority of diseases of the central nervous system may have been overlooked. The contributions compiled in this book describe in detail the individual techniques, outline their indications and limitations and deal in particular with newer methods such as the atraumatic 133Xe technique, stable xenon tomogra phy, three-dimensional techniques such as 133Xe single photon emission tomog raphy and N-isopropyl-P23-iodoamphetamine. Positron emission tomography studies provide information on function and metabolism, particularly that of oxygen and glucose, in regional brain areas of interest. Nuclear magnetic reso nance may be a promising method for studying metabolic parameters; however, accurate circulation measurements can not be performed at present.
