Age-associated changes in circulatory fatty acids: new insights on adults and long-lived individuals
2022
Long-lived individuals (LLIs) are considered an ideal model to study healthy human aging. Blood fatty acid (FA) profile of a cohort of LLIs (90–111 years old, n = 49) from Sicily was compared to adults (18–64 years old, n = 69) and older adults (65–89 years old, n = 54) from the same area. Genetic variants in key enzymes related to FA biosynthesis and metabolism were also genotyped to investigate a potential genetic predisposition in determining the FA profile. Gas chromatography was employed to determine the FA profile, and genotyping was performed using high-resolution melt (HRM) analysis. Blood levels of total polyunsaturated FA (PUFA) and total trans-FA decreased with age, while the lev…
The signature of longevity in Sicily
2019
Ageing is a natural and physiological condition that is the result of compromised stress response, homeostatic imbalance and increased risk of developing diseases. However, if aging with good health and functions (successful ageing) and aging with disease and disability (unsuccessful ageing) depends on a combination of “positive features”, including genetic, epigenetic and phenotypic characteristics in combination with favourable environment, economic status and social involvement. In our study, we summarize some key points for the identification of a longevity signature, with a particular focus on long-living Sicilian individuals and centenarians. Analysing three different Sicilian cohorts…
Proceedings of the Symposium “Updates in Pathobiology: Causality and Chance in Ageing, Age-related diseases and Longevity”
2017
The Symposium "Updates in Pathobiology: Causality and Chance in Ageing, Age-related diseases and Longevity" was held on March 24 in Palermo, 2017 (Sala delle Capriate, Palazzo Chiaramonte Steri), the day after exams for obtaining the title of PhD in Molecular Medicine and Biotechnology XXIX, Cycle (Coordinator Prof. Calogero Caruso) by seven PhD candidates; four of them have been awarded the title of Doctor Europaeus.
Ways to become old: Role of lifestyle in modulation of the hallmarks of aging
2021
Abstract Lifestyle represents one of the most relevant aspects in aging research since it is an important modifiable factor that affects aging process. A healthy lifestyle can limit the damage caused by environmental influences that face us each day. As gerontology says, there are two ways to become old, without success (unsuccessful aging), manifested by people that develop one or more age-related diseases, and with success (successful aging), defined as the process of developing and maintaining the functional ability, which enables well-being in older age. Among the lifestyle factors that may influence successful aging and longevity, physical activity and healthy dietary habits have a gre…
Palermo-2010 conference on biogerontology
2011
We, as the guest editors, are pleased to introduce this special issue of Biogerontology, which is the outcome from the 7th European Congress of Biogerontology, held from 14th to 17th October, 2010 in Palermo, Italy. The thematic aim of the Palermo-conference was to get an overview of the present state of research in the development of effective therapies to postpone or treat human ageing, focusing on predictive medicine and prevention of age-related diseases, immunosenescence, longevity, model systems, ageing and wellness, and vaccination in the elderly. Understanding the determinants of ageing in humans in relation to the living environment and the individual life history was the additiona…
Smoking, health and ageing.
2008
Abstract On March 19, 2008 a Symposium on Pathophysiology of Ageing and Age-Related diseases was held in Palermo, Italy. Here, the lecture of V. Nicita-Mauro on Smoking, health and ageing is summarized. Smoking represents an important ageing accelerator, both directly by triggering ana inflammatory responses, and indirectly by favoring the occurrence of several diseases where smoking is a recognized risk factor. Hence, non-smokers can delay the appearance of diseases and of ageing process, so attaining longevity.
Insulin/IGF-1 Signaling: More than a Metabolic Pathway
2014
Background: Dietary intervention and genetic alterations in gene encoding proteins involved in nutrient-sensing pathways can modulate lifespan, influencing longevity. It depends on under/over-expression of regulatory molecules that lead to different expression of homeostatic genes. Insulin/IGF-1 pathway was associated with longevity and lifespan modulation in model organisms. In humans, a key molecule in this pathway is FOXO3A that acts as a TF on homeostatic genes in response to decreased signaling increasing life span. Interestingly, other genes that increase lifespan interact with FOXO3A such as SIRT1, which modulates the oxidative stress response. Methods: We used meta-analytical and ca…
Longevity hotspot in Sicily. The exploration of a new possible blu zone
We are conducting a survey in some mountainous Sicilian populations, particularly in villages sited in the Palermo province, part of the Madonie Park. To ascertain the true longevity rate, we checked the born and death registers, analyzing about 37,000 newborns between 1881 and 1917 in a sample of five small municipalities located in Madonie. About 1,700 individuals died at the age of 90 years and over, and about one hundred were centenarians. Therefore, the probability to reach 90 and 100 years old was of 4.6% and 0.22% respectively. Accordingly, we observed significant lower mortality rates for all causes of death when compared to those measured in Palermo town. Therefore, the population …
16th IHIW: Immunogenetics of Aging
2013
Ageing is a process characterised by progressive loss of function in multiple different organ systems, such as the nervous, endocrine and immune systems. Current data showing that ageing processes may be associated with alterations in the immune system suggest that some of the genetic determinants of senescence might be polymorphic genes that regulate immune responses. The ‘Immunogenetics of Aging’ programme was a component introduced in the 14th International HLA and Immunogenetics Workshop (IHIWS) and developed further within the 15th and 16th. The aim of this component was to determine the contribution of immune genes to successful ageing and an increased capacity to reach the extreme li…
Cancro e Invecchiamento
2023
Gli studi epidemiologici hanno dimostrato che la mortalità per cancro aumenta con l’età fino al novantesimo anno, in cui raggiunge il plateau e quindi declina (Fig. 61.1). La mortalità per cancro è di circa il 40% dai 50 ai 70 anni e inferiore al 4% nei centenari. Questo non è strano perché è noto che i longevi ritardano o evitano quasi tutte le malattie infiammatorie legate all’età e il can-cro è una malattia in cui la componente infiammatoria gioca un ruolo rilevante........................................
