Factores de riesgo y protección del suicidio en personas mayores: una revisión sistemática
2021
La esperanza de vida se ha incrementado notablemente, no obstante, el suicidio es la principal causa de deceso no natural en la población mayor de 70 años. El objetivo de la presente investigación es revisar sistemáticamente los factores de riesgo y protección en la conducta suicida en personas mayores. Se llevó a cabo una revisión sistemática desde el enfoque PRISMA utilizando las bases de datos: PubMed, LILACS, SciELO, Google Académico y Dialnet. Se emplearon distintos descriptores en términos DeCS y MeSH con el operador booleano “AND” y, finalmente, teniendo en cuenta los criterios de inclusión y exclusión, obtuvimos 27 artículos. Los estudios revisados muestran que entre los factores de…
What Do We Know About the Second Moment of Financial Markets?
2021
Recent research shows that the vast majority of scientific studies published in leading finance journals fails scientific replication (Hou, Xue, and Zhang, 2020; Harvey, Liu, and Zhu; 2016). This study argues that p-hacking, publication pressure and the selection bias from leading finance journals are perhaps not the underlying root cause for this issue. We show that standard methodologies often used in finance research are inevitably sample-specific due to the very nature of financial markets. While the consensus of earlier research postulates a rejection of the time-honored Levy hypothesis, our results strongly indicate that the variance of variance does not exist in any of the financial …
Effects of Aging and Diet on Cardioprotection and Cardiometabolic Risk Markers.
2019
The prevalence of several diseases increases by age, including cardiovascular diseases, which are the leading cause of morbidity and mortality worldwide. Aging, as a complex process characterized by senescence, triggers various pathways, such as oxidative stress, systemic inflammation, metabolism dysfunction, telomere shortening, mitochondrial dysfunction and deregulated autophagy. A better understanding of the mechanisms underlying senescence may lead to the development of new therapeutic targets and strategies for age-related pathologies and extend the healthy lifespan. Modulating lifestyle risk factors and adopting healthy dietary patterns remain significant tools in delaying the aging …
Vascular aging in rodent models: contrasting mechanisms driving the female and male vascular senescence
2021
Increasing scientific interest has been directed to sex as a biological and decisive factor on several diseases. Several different mechanisms orchestrate vascular function, as well as vascular dysfunction in cardiovascular and metabolic diseases in males and females. Certain vascular sex differences are present throughout life, while others are more evident before the menopause, suggesting two important and correlated drivers: genetic and hormonal factors. With the increasing life expectancy and aging population, studies on aging-related diseases and aging-related physiological changes have steeply grown and, with them, the use of aging animal models. Mouse and rat models of aging, the most…

Morphological exponential entropy driven-HUM.
2006
This paper presents an improvement to the Ex- ponential Entropy Driven - Homomorphic Unsharp Masking (E 2 D − HUM ) algorithm devoted to illumination artifact sup- pression on Magnetic Resonance Images. E 2 D−HUM requires a segmentation step to remove dark regions in the foreground whose intensity is comparable with background, because strong edges produce streak artifacts on the tissues. This new version of the algorithm keeps the same good properties of E 2 D − HUM without a segmentation phase, whose parameters should be chosen in relation to the image. I. INTRODUCTION Most of the studies on illumination correction found in literature are oriented to brain (18) magnetic resonance images (…
The hidden side of the Ultimatum Game: The role of motivations and mind-reading in a two-level one-shot Ultimatum Game
2015
The main aim of our study is to investigate the role of motivations and mind-reading in a two-level one-shot Ultimatum Game with three players. Our intention is to analyse subjects’ behaviour in both the responder and proposer roles. In the responder role, we found that the difference between the subjects’ expectations and the actual offers was the major factor that influenced their decisions and motivations in receiving money. In the proposer role, our results showed a significant influence of mind-reading, with a positive association between the fairness of subjects’ offers and the subjects’ expectations about the recipients’ willingness to accept. Although a shared concept of fairness ex…
Equilibrium in a duopoly game with homogeneous adaptive expectations and isoelastic demand
2011
In this paper we consider a non linear discrete time Cournot duopoly game with isoelastic demand and where players have homogeneous adaptive expectations. The evolution of expected outputs over time is generated by the iteration of two-dimensional map and the long-run behavior is characterized by equilibrium points which are locally stable.
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…
Phenotypic Aspects of Longevity
2019
Centenarians are individuals who live over the average life span characteristic of their population. The growing number of old people worldwide makes it necessary to identify a good strategy to reach healthy ageing and avoid or delay age-related diseases. The longevity phenotype is the result of a positive combination between genetic, epigenetic, stochastic and lifestyle factors. So, the analysis of all the known parameters that can influence these single elements or their interaction can give new possible elements to delineate a sort of longevity signature. Starting from the easiest biomarkers as the haematochemical values and reaching the study of molecular and cellular components, as the…
