Book Description
As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.

Book Description
African Americans have the highest prevalence of hypertension in the world which may emanate from their predisposition to heightened endothelial inflammation. The purpose of this study was to evaluate the in vivo influence of aerobic exercise training (AEXT) on the anti-inflammatory biomarker interleukin-10 (IL-10), the inflammatory biomarkers interleukin-6 (IL-6) and C-reactive protein (CRP), the endothelial activation marker CD62E+ endothelial microparticle (EMP), and the vasodilatory biomarker nitric oxide (NO) in an African American cohort. A secondary purpose was to conduct a complementary in vitro study on the influence of IL-10 and laminar shear stress (LSS) on African American endothelial cells. In Vivo Methods: The subjects were sedentary, putatively healthy, 45-71 y/o African American men and women. A pre-post study design was employed with baseline and post-intervention evaluations of office blood pressure, fasting blood sampling, and graded exercise testing. Subjects engaged in AEXT three times per week for six months at an intensity equivalent to 65% of their VO2max. Plasma concentrations of IL-10 and IL-6 were determined using an enzyme-linked immunosorbent assay. Levels of nitric oxide metabolites (NOx) were determined using a modified Griess assay. Plasma samples for CRP were sent to Quest Diagnostics Inc. for analysis. Circulating CD62E+ EMPs were quantified using a flow cytometer. In Vitro Methods: Human umbilical vein endothelial cells (HUVEC) from an African American donor were cultured and exposed to four experimental conditions: Static, Static with IL-10 Incubation, LSS at 20 dynes/cm2, and LSS at 20 dynes/cm2 with IL-10 Incubation. Western blotting experiments were conducted to measure endothelial nitric oxide synthase (eNOS) protein expression and its phosphorylated form (p-eNOS) at Serine 1177 in the cells in all four conditions. A modified Griess assay was used to measure NOx in the cell culture supernatant. In Vivo Results: There was a significant increase in NO (n=24; p=0.002), a significant decrease in IL-6 (n=32; p=0.04), a significant decrease in CRP (n=37; p=0.01), and a significant decrease in CD62E+ EMPs (n=28; pIn Vitro Results: Protein expression levels of both eNOS and p-eNOS were significantly increased in the LSS at 20 dynes/cm2 and LSS at 20 dynes/cm2 with IL-10 Incubation experimental conditions when compared to the Static experimental condition. NO concentration levels were significantly increased in the LSS at 20 dynes/cm2 and LSS at 20 dynes/cm2 with IL-10 Incubation experimental conditions when compared to the Static experimental condition. Conclusion: Based on these results, AEXT may be a viable, non-pharmacologic method to improve vascular inflammation status and vasodilation, and thereby contribute to reduced hypertension and cardiovascular disease risk in African Americans.

Book Description
Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.

Book Description
The hormone cortisol, activated by the fight-or-flight (stress) response, is emerging as a major culprit in a variety of health problems. The Cortisol Connection explores the documented relationship between elevated levels of this hormone, chronic stress, and such health conditions as obesity, depression, suppressed immune system, osteoporosis, and hypertension. This new edition describes the results of the latest research about the connection between cortisol and HSD, and cortisol and testosterone.

Book Description
"[F]or those who are entering the field or who want to broaden their perspective, Ibelieve that this Handbook is indispensible. More than just a contribution to the field, theHandbook may well become a classic."--PsycCRITIQUES "The editors fully achieved their goal of producing a state-of-the-science stress reference for use by investigators, educators, and practitioners with clinical and health interests."--Psycho-Oncology "This is an important book about the scientific study of stress and human adaptation. It brings together both empirical data and theoretical developments that address the fundamental question of how psychosocial variables get inside the body to influence neurobiological processes that culminate in physical disease." From the Foreword by David C. Glass, PhD Emeritus Professor of Psychology Stony Brook University Edited by two leading health psychologists, The Handbook of Stress Science presents a detailed overview of key topics in stress and health psychology. With discussions on how stress influences physical health-including its effects on the nervous, endocrine, cardiovascular, and immune systems-the text is a valuable source for health psychologists, as well as researchers in behavioral medicine, neuroscience, genetics, clinical and social psychology, sociology, and public health. This state-of-the-art resource reviews conceptual developments, empirical findings, clinical applications, and investigative strategies and tools from the past few decades of stress research. It represents all major approaches to defining stress and describes the themes and developments that characterize the field of health-related stress research. The five sections of this handbook cover: Current knowledge regarding the major biological structures and systems that are involved in the stress response Social-contextual contributions to stress and to processes of adaptation to stress, including the workplace, socioeconomic status, and social support The concept of cognitive appraisal as it relates to stress and emotion psychological factors influencing stress such as, personality, gender, and adult development The evidence linking stress to health-related behaviors and mental and physical health outcomes Research methods, tools, and strategies, including the principles and techniques of both laboratory experimentation and naturalistic stress research

Book Description
Clinical practice related to sleep problems and sleep disorders has been expanding rapidly in the last few years, but scientific research is not keeping pace. Sleep apnea, insomnia, and restless legs syndrome are three examples of very common disorders for which we have little biological information. This new book cuts across a variety of medical disciplines such as neurology, pulmonology, pediatrics, internal medicine, psychiatry, psychology, otolaryngology, and nursing, as well as other medical practices with an interest in the management of sleep pathology. This area of research is not limited to very young and old patientsâ€"sleep disorders reach across all ages and ethnicities. Sleep Disorders and Sleep Deprivation presents a structured analysis that explores the following: Improving awareness among the general public and health care professionals. Increasing investment in interdisciplinary somnology and sleep medicine research training and mentoring activities. Validating and developing new and existing technologies for diagnosis and treatment. This book will be of interest to those looking to learn more about the enormous public health burden of sleep disorders and sleep deprivation and the strikingly limited capacity of the health care enterprise to identify and treat the majority of individuals suffering from sleep problems.
