Throughout the course of life, there are age-related changes in sleep. Despite these normal changes, is a high percentage older adults that report sleep dissatisfaction with pervasiveness chronic insomnia, most common disorder worldwide, its prevalence being expected to continuously increase due growing rates aging and obesity. This can have different adverse health outcomes, especially by promoting both physical cognitive decline, which ultimately may aggravate frailty adults. Moreover, dysfunction mechanism related hallmarks cellular aging. Cellular was categorized into nine hallmarks, such as DNA damage, telomere attrition epigenetic changes. In context geriatric insomnia research, this review aims at discussing current evidence from animal models human cohorts addressing link between their impact on frailty. recent research about putative effect therapeutic approaches will be also highlighted.

Having made substantial progress understanding molecules, cells, genes and pathways, aging biology research is now moving toward integration of these parts, attempting to understand how their joint dynamics may contribute aging. Such a shift perspective requires the adoption formal complex systems framework, transition being facilitated by large-scale data collection new analytical tools. Here, we provide theoretical framework orient researchers around key concepts for this transition, notably emergence, interaction networks resilience. Drawing on evolutionary theory, network theory principles homeostasis, propose that organismal function accomplished regulatory mechanisms at multiple hierarchical scales, disruption ensemble causes phenotypic functional manifestations We present examples scales ranging from sub-organismal clinical geriatrics, outlining approach can potentially enrich our The authors discuss adopting crucial step in advancing process fundamental alteration questions asked methods used answer them.

Aging is a major risk factor for number of chronic diseases, including neurodegenerative and cerebrovascular disorders. processes have therefore been discussed as potential targets the development novel broadly effective preventatives or therapeutics age-related those affecting brain. Mechanisms thought to contribute aging summarized under term "hallmarks aging" include loss proteostasis, mitochondrial dysfunction, altered nutrient sensing, telomere attrition, genomic instability, cellular senescence, stem cell exhaustion, epigenetic alterations intercellular communication. We here examine key claims about aging". Our analysis reveals important weaknesses that preclude strong definitive conclusions concerning possible role these in shaping organismal rate. Significant ambiguity arises from overreliance on lifespan proxy marker aging, use models with unclear relevance study designs do not allow properly estimate intervention effects also discuss future research directions should be taken clarify if what extent putative regulators fact interact aging.

Cardiovascular disease is the most common cause of death worldwide, especially beyond age 65 years, with vast majority morbidity and mortality due to myocardial infarction stroke. Vascular pathology stems from a combination genetic risk, environmental factors, biologic changes associated aging. The pathogenesis underlying development vascular aging, calcification in particular, still not fully understood. Accumulating data suggests that likely compounded by epigenetic modifications, including diabetes chronic kidney disease, plasticity smooth muscle cells acquire an osteogenic phenotype are major determinants age-associated calcification.

Abstract Ageing is inherent to all human beings, yet why we age remains a hotly contested topic. Most mechanistic explanations of ageing posit that caused by the accumulation one or more forms molecular damage. Here, I propose not because inevitable damage hardware but rather intrinsic design flaws in software, defined as DNA code orchestrates how single cell develops into an adult organism. As developmental software runs, its sequence events reflected shifting cellular epigenetic states. Overall, suggest understand need decode our and flow information throughout life course.

The pursuit for the fountain of youth has long been a fascination amongst scientists and humanity. Ageing is broadly characterized by cellular decline with increased susceptibility to age-related diseases, being intimately associated epigenetic modifications. Recently, reprogramming-induced rejuvenation strategies have begun greatly alter longevity research not only tackle defects but also possibly reverse ageing process. Hence, in this review, we highlight major changes during state-of-art current emerging reprogramming leveraging on transcription factors. Notably, partial enables resetting clock without erasing identity. Promising chemical-based harnessing small molecules, including DNA methyltransferase histone deacetylase inhibitors are discussed. Moreover, parallel interventions, foundations clocks accurate assessment evaluation approaches briefly presented. Going further, such scientific breakthroughs, witnessing rise biotech industry aiming extend health span ideally achieve human one day. In context, overview main scenarios proposed future socio-economic ethical challenges an field. Ultimately, review aims inspire interventions that promote healthy all.

Why and how we age are 2 intertwined questions that have fascinated scientists for many decades. However, attempts to answer these remain compartmentalized, preventing a comprehensive understanding of the aging process. We argue current lack knowledge about evolution mechanisms is due clarity regarding evolutionary theories explicitly involve physiological processes: disposable soma theory (DST) developmental (DTA). In this Essay, propose new hierarchical model linking genes vital rates, enabling us critically reevaluate DST DTA in terms their relationship genetic (mutation accumulation (MA) antagonistic pleiotropy (AP)). also demonstrate can be incorporated unified framework. The framework will help generate testable hypotheses hallmarks shaped by natural selection.

Abstract Sex differences in aging occur many animal species, and they include sex lifespan, the onset progression of age‐associated decline, physiological molecular markers aging. vary greatly across kingdom. For example, there are species with longer‐lived females, where males live longer, lacking lifespan. The underlying causes remain mostly unknown. Currently, we do not understand drivers aging, or whether related to accepted hallmarks pillars linked other well‐characterized processes. In particular, understanding role sex‐determination mechanisms is relatively understudied. Here, take a comparative, interdisciplinary approach explore various hypotheses about how arise. We discuss genomic, morphological, environmental between sexes these relate Finally, present some suggestions for future research this area provide recommendations promising experimental designs.
