This book was released on 2019 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines the contribution of various psychological and social stressors to indicators of cardiovascular and metabolic function and disease. It also investigates the role of altered hypothalamic pituitary adrenal (HPA) axis activity as a mechanism by which psychosocial stress may influence cardiometabolic health. Grounded in the framework of the allostatic load model, studies 1-3 build on each other to assess the interplay between various types of stress, HPA axis indicators, and cardiometabolic health outcomes among diverse populations. Study 1 examines the association of perceived everyday discrimination and hair cortisol concentration, a stable indicator of retrospective cortisol output indexed over several months. The analyses focus on racial group differences, finding that perceived discrimination scores were associated with elevated hair cortisol concentration for African American adults but not White adults. Given that both groups reported similar discrimination frequency scores, this finding suggests that more qualitative characteristics of discrimination may be particularly salient to HPA axis output among African Americans. Study 2 moves one step past the stress-HPA axis association by examining the role that elevated HPA axis activity plays in the association between perceived stress and metabolic syndrome severity. This study found that psychological resilience protected against the association of elevated perceived stress with increased metabolic syndrome severity via elevated hair cortisol concentration. Study 3 uses the same resilience-based framework as study 2, but does so in a national longitudinal cohort of U.S. adults. Using daily diary entries and salivary cortisol analysis, this study examines unique effects of daily stressor frequency and severity on cardiovascular and metabolic disease prevalence 5-8 years later. Study 3 also tests whether flattened diurnal salivary cortisol slopes mediator effects of stressor frequency and severity on cardiometabolic conditions, and examines a latent resilience resources variable as a potential buffer of the daily stress-cardiometabolic disease relationship. Findings indicate that greater perceived stressor severity and flattened diurnal cortisol slopes predict greater cardiometabolic disease prevalence later in life. Taken together, this collection of studies provides evidence supporting the contribution of greater psychosocial stress to impaired cardiovascular and metabolic health, and suggests that the HPA axis plays a significant role

Download or read book The Hypothalamus Pituitary Adrenal Axis written by and published by Elsevier. This book was released on 2008-09-12 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hypothalamic-pituitary-adrenal axis controls reactions to stress and regulates various body processes such as digestion, the immune system, mood and sexuality, and energy usage. This volume focuses on the role it plays in the immune system and provides substantive experimental and clinical data to support current understanding in the field, and potential applications of this knowledge in the treatment of disease. Evidence presented in this book suggests that the nervous, endocrine, and immune systems form the Neuroendoimmune Supersystem, which integrates all the biological functions of higher organisms both in health and disease for their entire life cycle Contributors include both the scientists who initiated the work on the HPA axis and on the autonomic nervous system, and those who joined the field later

Download or read book Stress Challenges and Immunity in Space written by Alexander Choukèr and published by Springer Nature. This book was released on 2019-11-27 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains how stress – either psychological or physical – can activate and/or paralyse human innate or adaptive immunity. Adequate immunity is crucial for maintaining health, both on Earth and in space. During space flight, human physiology is specifically challenged by complex environmental stressors, which are most pronounced during lunar or interplanetary missions. Adopting an interdisciplinary approach, the book identifies the impact of these stressors – the space exposome – on immunity as a result of (dys-)functions of specific cells, organs and organ networks. These conditions (e.g. gravitation changes, radiation, isolation/confinement) affect immunity, but at the same time provide insights that may help to prevent, diagnose and address immune-related health alterations. Written by experts from academia, space agencies and industry, the book is a valuable resource for professionals, researchers and students in the field of medicine, biology and technology. The chapters “The Impact of Everyday Stressors on the Immune System and Health”, “Stress and Radiation Responsiveness” and “Assessment of Radiosensitivity and Biomonitoring of Exposure to Space adiation” are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Download or read book Stress and Cardiovascular Disease written by Paul Hjemdahl and published by Springer Science & Business Media. This book was released on 2011-10-01 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main aim of this book is to evaluate the concept of stress and provide tools for physicians to identify patients who might benefit from stress management. This will incorporate a detailed description of the physiological and pathophysiological consequences of acute and chronic stress that might lead to cardiovascular disease. The book will aim to critically evaluate interventional research (behavioural and other therapies) and provide evidence based recommendations on how to manage stress in the cardiovascular patient. Our intentions are to define and highlight stress as an etiological factor for cardiovascular disease, and to describe an evidence based "tool box" that physicians may use to identify and manage patients in whom stress may be an important contributing factor for their disease and their risk of suffering cardiovascular complications.

Download or read book ACTH Action in the Adrenal Cortex From Molecular Biology to Pathophysiology written by Nicole Gallo-Payet and published by Frontiers Media SA. This book was released on 2017-07-27 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: By stimulating adrenal gland and corticosteroid synthesis, the adrenocorticotropic hormone (ACTH) plays a central role in response to stress. In this Research Topic, a particular attention has been given to the recent developments on adrenocortical zonation; the growth-promoting activities of ACTH; the various steps involved in acute and chronic regulation of steroid secretion by ACTH, including the effect of ACTH on circadian rhythms of glucocorticoid secretion. The Research Topic also reviews progress and challenges surrounding the properties of ACTH binding to the MC2 receptor (MC2R), including the importance of melanocortin-2 receptor accessory protein (MRAP) in MC2R expression and function, the various intracellular signaling cascades, which involve not only protein kinase A, the key mediator of ACTH action, but also phosphatases, phosphodiesterases, ion channels and the cytoskeleton. The importance of the proteins involved in the cell detoxification is also considered, in particular the effect that ACTH has on protection against reactive oxygen species generated during steroidogenesis. The impact of the cellular microenvironment, including local production of ACTH is discussed, both as an important factor in the maintenance of homeostasis, but also in pathological situations, such as severe inflammation. Finally, the Research Topic reviews the role that the pituitary-adrenal axis may have in the development of metabolic disorders. In addition to mutations or alterations of expression of genes encoding components of the steroidogenesis and signaling pathways, chronic stress and sleep disturbance are both associated with hyperactivity of the adrenal gland. A resulting effect is increased glucocorticoid secretion inducing food intake and weight gain, which, in turn, leads to insulin and leptin resistance. These aspects are described in detail in this Research Topic by key investigators in the field. Many of the aspects addressed in this Research Topic still represent a stimulus for future studies, their outcome aimed at providing evidence of the central position occupied by the adrenal cortex in many metabolic functions when its homeostasis is disrupted. An in-depth investigation of the mechanisms underlying these pathways will be invaluable in developing new therapeutic tools and strategies.

Download or read book The Cambridge Handbook of Cognitive Aging written by Ayanna K. Thomas and published by Cambridge University Press. This book was released on 2020-05-28 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.

Download or read book Handbook of Nutrition Diet and Epigenetics written by Vinood B. Patel and published by Springer. This book was released on 2019-02-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume reference work addresses the fact that the well being of humankind is predicated not only on individuals receiving adequate nutrition but also on their genetic makeup. The work includes more than 100 chapters organized in the following major sections: Introduction and Overview; Epigenetics of Organs and Diseases in Relation to Diet and Nutrition; Detailed Processes in Epigenetics of Diet and Nutrition; Modulating Epigenetics with Diet and Nutrition; and Practical Techniques. While it is well known that genes may encode proteins responsible for structural and dynamic components, there is an increasing body of evidence to suggest that nutrition itself may alter the way in which genes are expressed via the process of epigenetics. This is where chemically imposed alteration in the DNA sequence occurs or where the functional expression of DNA is modulated. This may include changes in DNA methylation, non-coding RNA, chromatin, histone acetylation or methylation, and genomic imprinting. Knowledge regarding the number of dietary components that impact on epigenetic processes is increasing almost daily. Marshalling all the information on the complex relationships between diet, nutrition, and epigenetic processes is somewhat difficult due to the wide myriad of material. It is for this reason that the present work has been compiled.

Download or read book Psychobiology of Stress written by Stefano Puglisi-Allegra and published by Springer Science & Business Media. This book was released on 1990-10-31 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a historical point of view the first studies on the response of the organism to stressful situations in general, and on the psychobiology of stress in particular, are probably those of Cannon and de la Paz, the physiologists who showed in 1911 that the adrenal medulla and the sympathetic system are involved in emergency situations. Cannon noted that the venous blood of cats frightened by barking dogs contained adrenaline, a response of the organism which was prevented by adrenalectomy or by section of the splanchnic nerve innervating the adrenal medulla. Cannon suggested that the adrenal medulla was acting in concert with the sympathetic nervous system, so that both systems were activated during stress. The role of the sympathetic system in response to stressful events was later emphasized by the experiments carried out by Maickel et al. (1967) and by Mason (1968): these authors clearly showed that stressors activate the sympathetic system causing it to release adrenaline and noradrenaline. This line of research may be contrasted with that carried out by Hans Selye, centered on of the adrenal cortex in the stress response. Selye's findings and theories originated the role the so-called hypothalamic - pituitary - adrenal cortex (HPA) model of stress: in short, during stress adrenocorticotropic hormone is released from cells of the anterior pituitary and elicits secretion of glucocorticoids from the adrenal cortex.
