Mechanisms Of Cardiovascular Aging by Tory Hagen


Original Title: Mechanisms Of Cardiovascular Aging

This volume of Advances in Cell Aging and Gerontology provides a timely review on the molecular and cellular basis of cardiovascular diseases (CVD). Age itself is the leading risk factor for cardiovascular diseases, which include loss of vasomotor function, athero- and arterio-sclerosis, hypertension, congestive heart failure and stroke. Together these pathologies comprise the leading causes of permanent disability, hospitalization and death for individuals over the age of 65. Thus, there is a critical need to assess both the age-associated causes leading to CVD as well as the current state of knowledge on preventive regimens designed to slow or modulate disease progression. This book concisely summarizes the current knowledge related to the major aspects contributing to cardiovascular disfunction in the elderly as well as potential ways of maintaining or improving human cardiovascular healthspan.

Signaling In The Heart by José Marín-García


Original Title: Signaling In The Heart

Signal transduction pathways are at the core of most biological processes and are critical regulators of heart physiology and pathophysiology. The heart is both a transmitter and dynamic receptor of a variety of intracellular and extracellular stimuli, playing a critical role of an integrator of diverse signaling mechanisms. Alterations in signaling pathways are contributing factors in the development and progression of a broad spectrum of diseases, ranging from dysrhythmias and atherosclerosis to hypertension and the metabolic syndrome. Targeting specific components of these signaling pathways has been shown to be effective in preclinical studies with significant therapeutic impact. This book brings together current knowledge in cardiovascular cell signal transduction mechanisms, advances in novel therapeutic approaches to improve cardiac function, and discussion of future directions. Presented from a post-genomic perspective, this exciting book introduces important new ideas in cardiovascular systems biology. It is an invaluable reference for cardiology researchers and practitioners.

Recent Advances In Psychology And Aging by P. Costa


Original Title: Recent Advances In Psychology And Aging

Recent Events in the Psychology of Aging documents the successful integration of aging into the mainstream of psychology. Leading psychologists present overviews of the key issues and research findings on mainstream topics. These include cognitive neuroscience, visual attention, learning, memory and cognition, as well as personality and happiness. The intersection of aging content with mainstream psychology is also prominent in the areas of emotions, personality, and social psychology as seen in the chapters on subjective well-being, emotional development, self-esteem and personality trajectories. The seven chapters of this book offer information on such topics as: the seven sins of memory, categorizing the common breakdowns of memory in everyday life and the special breakdown of sins that increase with aging; problems with attention and learning; and offers answers to questions such as do emotions get blunted with age; do older people focus more on positive feelings; and the age old question of whether older people are happier than younger people is given in the chapter on the evolving concept of subjective well-being and the multifaceted nature of happiness. Questions about what occurs to one's self-esteem and personality are also masterfully discussed and the answers may be surprising. The concluding seventh chapter provides a cultural lens on the biopsychosocial study of aging.

Vascular Aging Facts And Factors by Elisabet Vila


Original Title: Vascular Aging Facts And Factors

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.

Nutrition Exercise And Epigenetics Ageing Interventions by Byung Pal Yu


Original Title: Nutrition Exercise And Epigenetics Ageing Interventions

This book focuses on the three most important aspects of ageing research: nutrition, physical exercise and epigenetics. The contributors discuss ways that age-related epigenetic imprints such as DNA methylation and histone acetylation are modified by these two interventions. The emphasis on epigenetics helps to illuminate the underlying mechanisms of anti-ageing interventions, as ageing and disease are predominately epigenetic phenomena. Among the highlights are chapter-length discussion of such topics as: how anti-inflammatory action of calorie restriction underlies the retardation of ageing and age-related diseases (Chapter 3); epigenetic modification of gene expression by exercise (Chapter 5); the role of functional foods and their bioactive components in bone health (Chapter 8); and an account of the first decade of a study of calorie restriction in nonhuman primates, conducted by the National Institute on Ageing.
