The lymphatic system develops and functions in parallel with the blood circulatory system (termed the "hemovasculature") and accomplishes transport of interstitial fluids, dietary lipids, and reverse transport of cholesterol, immune cells, and antigens-providing a critical homeostatic fluid balance and transmission of immune cells and mediators back to the cardiovascular system. Although the daily flow of lymph (normally 1-2 L/day under unstressed conditions) is far lower than that of daily blood flow (which is 7,500 L/day), without the adequate functioning of the lymphatics, virtually all organs and tissues would acutely suffer many different physical and inflammatory stresses ranging from edema to organ system failure. Although blood and lymphatic vessels often form in anatomic parallels to one another, our knowledge of the workings of the lymphatic system, the fine structure of lymphatic networks, how they function in different organs, and how they are regulated physiologically and immunologically are far from parallel; our knowledge of the lymphatic system still remains at only a tiny fraction of what is understood about the cardiovascular system. Although both the cardiovascular and lymphatic systems are important transport systems, what they transport and how they transport and propel these very different cargoes could not be more dissimilar. This book provides an overview of the history of the discovery (and re-discovery) of the components of the lymphatic system, lymphatic anatomy, physiological functions of lymphatics, molecular features of the lymphatic system, and clinical perspectives involving lymphatics which may be of interest to scientists, clinicians, patients, and the lay public. We provide a current understanding of some of the more important structural similarities and differences between lymphatics and the blood vascular system, their coordinated control by angiogenic and hemangiogenic growth factors and other modulators, the fate and lineage determinants which control lymphatic development, and the roles that lymphatics may play in several different diseases.

Hurricane Katrina forced the largest and most abrupt displacement in U.S. history. About 1.5 million people evacuated from the Gulf Coast preceding Katrina's landfall. New Orleans, a city of 500,000, was nearly emptied of life after the hurricane and flooding. Katrina survivors eventually scattered across all fifty states, and tens of thousands still remain displaced. Some are desperate to return to the Gulf Coast but cannot find the means. Others have chosen to make their homes elsewhere. Still others found a way to return home but were unable to stay due to the limited availability of social services, educational opportunities, health care options, and affordable housing. The contributors to Displaced have been following the lives of Katrina evacuees since 2005. In this illuminating book, they offer the first comprehensive analysis of the experiences of the displaced. Drawing on research in thirteen communities in seven states across the country, the contributors describe the struggles that evacuees have faced in securing life-sustaining resources and rebuilding their lives. They also recount the impact that the displaced have had on communities that initially welcomed them and then later experienced "Katrina fatigue" as the ongoing needs of evacuees strained local resources. Displaced reveals that Katrina took a particularly heavy toll on households headed by low-income African American women who lost the support provided by local networks of family and friends. It also shows the resilience and resourcefulness of Katrina evacuees who have built new networks and partnered with community organizations and religious institutions to create new lives in the diaspora.

A chronicle that has been judged the 'single most authentic document of its kind.' Based on testimonies from descendants of Inca kings, who in the 1540s-50s still remembered the oral history and traditions of their ancestors. Beginning in 1551, Betanzos transcribed their memories and translated them from Quechua by order of Viceroy Antonio de Mendoza. Pt. I covers Inca history prior to the Spanish arrival and Pt. II deals with the conquest to 1557, mainly from the Inca point of view"--Handbook of Latin American Studies, v. 58.

Environmental heat stress is associated with a marked decrease in orthostatic tolerance (OT), which is defined as the ability to stand or sit upright without symptoms of dizziness, lightheadedness, presyncope, or fainting. In most healthy humans, the autonomic nervous system makes rapid and balanced adjustments to heart rate and peripheral blood flow, such that most people are able to stand up "successfully" most of the time, in most environments. The goal of this book is to discuss various aspects of the sympathetic neural response to heat stress, how the sympathetic nervous system coordinates the successful integrative physiological response to orthostasis, and what happens when it encounters both challenges simultaneously. We include overviews of mechanisms of thermoregulation and blood pressure regulation in humans, with particular focus on control of cardiac output and neurovascular control mechanisms during heat stress. We discuss the implications that these changes have for distribution of peripheral blood flow and, in particular, for blood flow to the cerebral circulation. The added stressor of dehydration is also discussed, as it so often goes hand in hand with heat stress. We end with a brief presentation of countermeasures against the decreases in OT with heat stress.

The focus of Richard Zgusta's The Peoples of Northeast Asia through Time is the formation of indigenous and cultural groups of coastal northeast Asia, including the Ainu, the "Paleoasiatic" peoples, and the Asiatic Eskimo. Most chapters begin with a summary of each culture at the beginning of the colonial era, which is followed by an interdisciplinary reconstruction of prehistoric cultures that have direct ancestor-descendant relationships with the modern ones. An additional chapter presents a comparative discussion of the ethnographic data, including subsistence patterns, material culture, social organization, and religious beliefs, from a diachronic viewpoint. Each chapter includes maps and extensive references.

The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of 1-adrenoceptors and increase renin secretion rate by activation of 1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Under normal conditions, the renal mechanosensory nerves activated by stretch of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

What is multiculturalism? The word is used everywhere, often without being clearly defined. The first collection of this scope, Mapping Multiculturalism offers cogent critiques of the term and its uses by leading scholars in sociology, history, literary criticism, popular culture studies, ethnic studies, and critical legal studies. The contributors look at current uses of the rubric "multicultural" and offer groundbreaking analyses of complex relationships between popular culture, political events, and intellectual trends. Featuring essays by authors, activists, artists, and theoreticians, Mapping Multiculturalism represents the entire range of multicultural studies today through essays that demarcate the cutting edge of contemporary cultural politics.
