The underlying mechanisms behind aging has long been a great scientific mystery that the biomedical research community has long studied. In developed nations, as the population grows older, increases in life expectancy is increasingly limited by our relatively poor control of chronic aging-associated diseases such as arterial aging. Among age-related conditions that negatively influence longevity. Growing evidence demonstrates that arterial aging is fundamentally caused by a proinflammatory process that begins at birth and results in detrimental effects that affects every organ system. Vascular aging is the leading risk factor for quintessential cardiovascular diseases such as hypertension and atherosclerosis. With aging, vascular walls develop a pro-inflammatory and stressed microenvironment characterized by both an upregulation of pro-inflammatory chemokines and cytokines as well as a down-regulation anti-inflammatory counterparts. This chronic imbalance in inflammatory regulatory networks is the key driver of changes at the cellular and molecular level that result in hypertensive and atherosclerotic arterial. Thus, an intervention of proinflammation may be a viable therapeutic intervention to reduce morbidity and mortality from cardiovascular diseases. In this eBook, we aim to supply an updated overview of the physiological and biochemical mechanisms that affect inflammation and vascular aging. We believe that this eBook will contribute to the understanding of the pathogenesis of many chronic or age-related diseases, as well as to their treatment with both current and new therapeutic approaches.

The increasing mean age of the population in developed countries has turned out to be an economic and social problem. Cardiovascular disease has long been considered to be age related in terms of their onset and progression. As such, we can say that the increase in life expectancy goes in parallel with increased incidence of cardiovascular disease. With age, a number of changes occur in the vasculature altering the homeostasis of the irrigated organs promoting target organ damage. While different adaptive mechanisms to protect vessels against mild stress have been described, the aging process induces a progressive failure of protective mechanisms, leading to vascular changes and higher susceptibility to cardiovascular diseases. Indeed, vascular aging is exacerbated by coexisting cardiovascular risk factors, such as hypertension, metabolic syndrome and diabetes. Compelling evidence indicates that diminished endothelial relaxation and increase, decrease, or no change in contractile responses to several agonists is associated with aging. There is an increase of vasoconstrictor factors expression and a decrease of vasodilators. Morphologic changes include lumen diameter enlargement, wall thickening and alterations of matrix substances as increased collagen or decreased elastin deposition, ultimately leading to greater arterial stiffening (reduced compliance). Importantly, arterial stiffness is an independent predictor of cardiovascular morbidity and mortality. Cellular and molecular mechanisms have also been documented. Senescence at the cellular level involves alterations in Ca2+ signaling and down regulation of anti-aging proteins. Both endothelial and smooth muscle cells change their number, morphology, function and their regenerative ability. Aging is also associated with a gradual loss of antioxidant defense mechanisms, a proinflammatory shift in the cytokine expression profile and a production of reactive oxygen species such as superoxide (O2-) that promotes the breakdown of nitric oxide. Nitric oxide and O2- interact to form peroxynitrite known to nitrosylate proteins affecting their physiological function. However, vascular wall proteins may also suffer from other potentially deleterious modifications as glycation (Maillard reaction) and glyco-oxidative reactions with increasing age, which could be linked to the age-associated changes in vascular function. Various strategies have shown benefit in preventing, delaying or attenuating vascular aging. For instance, a healthy lifestyle including low fat diet and/or exercise have a favorable effect. Nevertheless, it yet remains to be fully demonstrated whether vascular aging can be pharmacologically prevented. This Research Topic is intended to bring together research efforts to understand the causes and consequences of vascular aging and propose new therapeutic strategies for the management of vascular senescence.

Download The Cambridge Handbook of Successful Aging Book in PDF, ePub and Kindle
Recent studies show that more people than ever before are reaching old age in better health and enjoying that health for a longer time. This Handbook outlines the latest discoveries in the study of aging from bio-medicine, psychology, and socio-demography. It treats the study of aging as a multidisciplinary scientific subject, since it requires the interplay of broad disciplines, while offering high motivation, positive attitudes, and behaviors for aging well, and lifestyle changes that will help people to stay healthier across life span and in old age. Written by leading scholars from various academic disciplines, the chapters delve into the most topical aspects of aging today - including biological mechanisms of aging, aging with health, active and productive aging, aging with satisfaction, aging with respect, and aging with dignity. Aimed at health professionals as well as general readers, this Cambridge Handbook offers a new, positive approach to later life.

In this book, the genetic and molecular basis of cardiovascular aging is examined in detail and a comprehensive assessment given of the bioenergetics changes occurring in human and animal models of cardiac aging. Both current diagnostic and future therapeutic modalities are presented, giving this book a dual-pronged approach. Cardiac aging, like aging in general, is a complex process involving numerous cellular and molecular changes. This book sheds new light on the phenomenon.

Download Endothelial Dysfunction Book in PDF, ePub and Kindle
The endothelium enables communication between blood and tissues and is actively involved in cardiovascular homeostasis. Endothelial dysfunction has been recognized as an early step in the development of cardiovascular diseases: respectively, endothelium represents a potential therapeutic niche with multiple targets. The purpose of the book is to point out some recent findings of endothelial physiology and pathophysiology emphasizing various aspects of endothelial dysfunction connected to the body's internal and external environment. While basic features of the endothelium are presented in an introductory chapter, the authors of the following 17 chapters have provided extensive insight into some selected topics of endothelial (dys)function. The book would hopefully be useful for anyone interested in recapitulating endothelial (patho)physiology and expanding knowledge of molecular mechanisms involved in endothelial dysfunction, relevant also for further clinical investigations.
