This edited volume studies gut microbiota peculiarities in elderly, in senescence-related  and environmental-related alterations of gut microbiota in chronic diseases.Aging, as a physiological process mediated through several regulatory pathways and transcription factors, is generally speaking associated to a relentless functional decline and increasing risk of chronic diseases. Growing data on gut microbiota quali-quantitative changes in aging gut, and the opportunity to study by advanced NGS and metabolomic technologies, now offers novel horizons to link such changes to disease risks and...

This edited volume focuses on the interplay between sleep and circadian rhythms with health, aging and longevity. Sleep is absolutely important for human health and survival, as insufficient sleep is associated with a plethora of conditions, including the poor quality of life, onset of several diseases, and premature death. The sleep–wake cycle is an evolutionary conserved neurobiological phenomenon, and is a prominent manifestation of the biological clocks localised in the suprachiasmatic nucleus (SCN). Understanding bidirectional relationship between sleep and circadian rhythms is of...

This book aims to present the age-related alterations in redox signaling networks and their diagnostic biomarkers in aging cells using multidisciplinary approach. Establishing sensitive and specific biomarkers of dynamic redox homeostasis is crucially important in the development of effective antiaging and senolytic interventions. Recent years have seen tremendous advances in the understanding of redox signaling events which highlight the process of aging and age-related pathologies. A major challenge in biological aging research is developing reliable biomarkers to determine the consequences...

This book presents studies of the main conditions that affect health and well-being of old people. Considering the present scenario of COVID-19, the effects of this viral infection on individuals older than 65 years are also discussed. The content enables professionals of health and government for the present and future actions in this important area.Readers go through  the changes occurring in organs and tissues that can interfere with susceptibility to infections, low response to vaccines, cancer, and loss of cognition during the aging process.A discussion of the central role played by the...
