Non-response bias as a likely cause of the association between young maternal age at the time of delivery and the risk of cancer in the offspring.

2003

Some epidemiological studies have shown an association between young maternal age at the time of delivery and risk of cancer in the offspring. In a recent German case-control study, there was a twofold increase in the leukaemia risk for children whose mothers were aged < 20 years at the time of delivery. As the prevalence of younger mothers among control families was particularly low, data on maternal age distributions for the general population of Germany were obtained in order to examine the representativeness of the control sample. Despite the excellent sampling frame based on data from complete and up-to-date population registries and a satisfactory response rate among controls ( approx…

Internal spring distribution for quasi brittle fracture via Symmetric Boundary Element Method

2009

Abstract In this paper the symmetric boundary element formulation is applied to the fracture mechanics problems for quasi brittle materials . The basic aim of the present work is the development and implementation of two discrete cohesive zone models using Symmetric Galerkin multi-zone Boundary Elements Method . The non-linearity at the process zone of the crack will be simulated through a discrete distribution of nodal springs whose generalized (or weighted) stiffnesses are obtainable by the cohesive forces and relative displacements modelling. This goal is reached coherently with the constitutive relation σ − Δ u that describes the interaction between mechanical and kinematical quantities…

Long-term effects of delayed parenthood.

1998

The present study aims to define, characterize and compare the long-term effects on offspring of delayed parenthood. Data published so far on this topic show that maternal and paternal ageing may affect offspring by different mechanisms. Delayed motherhood is characterized by increased probability of obstetric complications and/or fetal and perinatal problems which, in turn, may increase the risks of mortality and morbidity in newborns and later life. Furthermore, maternal ageing is distinguished by a decreased ratio of male to female infants and higher odds of conceiving a trisomic child and/or an individual suffering from mitochondrial DNA disorders. In contrast, delayed fatherhood is ass…

Drinking pattern matters: effects on maternal care and offspring vulnerability to alcohol in rats

2015

Alcohol drinking during pregnancy and post-partum period is a major concern because of the persistent neurobehavioral deficits in the offspring, which include increased vulnerability to substance abuse (1). The intermittent pattern of alcohol consumption induces higher drinking levels and deeper neurobiological changes in addiction-related brain regions, with respect to traditional free-access paradigms in male rats (2, 3). Nevertheless, no studies investigated on the effects of the drinking pattern on female subjects during pregnancy and perinatal time. To this aim, this study explored the consequences of continuous vs. intermittent drinking pattern on maternal behaviour and on offspring v…

Physical Metaphor for Streaming Media Retargeting

2014

We here introduce an image/video retargeting method that operates arbitrary aspect ratios resizing achieved in real-time performances. Most of the literature retargeting approaches sacrifice real-time performances in behalf of quality. On the other hand, existing fast methods provide arguable results. We can obtain a valuable trade-off between effectiveness and efficiency. The method named Spring Simulation Retargeting (SSR) is mainly based on a physical springs-based simulation. The media are assumed as flexible objects composed of particles and springs with different local stiffness properties, related to the visual importance of the content. The variation of the object size generates ela…

I thermà loutrà di Termini Imerese dalla presenza mitica di Eracle alle terme romane

2019

Le sorgenti calde di Termini Imerese sono legate nel mito raccontato da Diodoro alla presenza di Eracle fin dall'età arcaica. La popolarità dell'eroe nell'isola è confermata dall'evidenza archeologica non solo nella colonia greca di Himera, ma anche nel suo territorio. E' probabile che un edificio termale esistesse nell'area prima dell'età romana, ma è solo dopo la deduzione di una colonia romana a Thermae in età augustea che venne costruito un edificio monumentale riccamente decorato, messo parzialmente in luce da recenti scavi. The thermal springs of Termini Imerese are linked in myth to the presence of Herakles from the Archaic period. The relationship between the tale told by Diodoros o…

The role of immune response in ageing and longevity. A focus on B cell compartment

2017

The improvement of the quality of life of elderly people is going to become a priority because of the continuous increase in the number of centenarians. This render the studies of the processes involved in ageing of critical importance. Centenarians are a widely accepted model of successful ageing, a complex process which is influenced by several biological, environmental and lifestyle factors, because they have reached the extreme limits of life span overcoming the major age-related diseases. In centenarians model, several aspects have been studied, as inflammation, immune system, genetics and metabolism, to understand the secret of their long survival. It has been proposed that centenaria…

B CELL CHANGES IN AGING

2014

The aging of the immune system is a gradual and dynamic process that modifies some immunological functions. These changes are known as “immunosenescence” that have a great impact on immune performance in late life, contributing to the decreased ability of the elderly people to respond to emerging pathogens and to the decreased responsiveness to vaccinations. It is known that the adaptive immune functions are affected in the aged. In particular, with aging, the acquired compartment of the immune system shows significant modifications in both T and B cell branches. Thus, the adaptive immune response of elderly people is qualitatively and quantitatively reduced when compared to that observed i…
