Dietary Patterns and Healthy Ageing
2021
Ageing is a complex process in which multiple factors are involved that can contribute to determine whether a person will or not be affected by diseases that are more frequently observed in advanced age. The factors involved comprise genetic, environmental, behavioural, and dietary factors, which influence pathways that regulate the ageing process and the life expectancy, rendering longevity a multifaceted phenomenon. Even if a miraculous elixir or pill is not yet available, there is general agreement that nutrition has a major impact on the overall mortality and on the development of age-related chronic non-communicable diseases. Nutrition research has focused for decades on single nutrien…
Multifibrillar bundles of a self-assembling hyaluronic acid derivative obtained through a microfluidic technique for aortic smooth muscle cell orient…
2018
A hyaluronic acid derivative that is able to physically crosslink in a saline aqueous environment was employed for the production of fibers with a mean diameter of 50 μm using a microfluidic technique. The microfibers were collected in a tailored rotating collector and assembled to form multifibrillar bundles. The orientation of the microfibers on the collected bundles was evaluated by microCT analysis. The bundles were biofunctionalized by physical addition of fibronectin or chemical tethering of a cyRGDC peptide to achieve control of Aortic Smooth Muscle Cell (AoSMC) attachment, elongation and alignment. The mechanical performances of these bundles were evaluated by elongation tests, rela…
Sport and Quality of Life
2022
Negli ultimi trent’anni lo sport ha assunto un significato molto rilevante nella vita delle persone e, seppure con notevoli differenze, sia nei paesi a sviluppo economico avanzato, sia in quelli in via di sviluppo. A livello individuale, esso ha costituito un’area di investimento identitario quando ha assunto la forma di sport spettacolo del quale fruire, alimentando la pratica del tifo e il fandom o costituendo il modello di uno stile di vita vincente; ma anche quando ha assunto la forma di pratica del tempo libero attraverso la quale tenersi in forma, facendo crescere, in questo caso, la diffusione di una cultura della salute e del benessere. Si tratta di due modalità di approcciare al co…
Externalizing Behaviors and Cigarette Smoking as Predictors for Use of Illicit Drugs: A Longitudinal Study Among Finnish Adolescent Twins
2010
We examined whether externalizing problem behaviors (hyperactivity–impulsivity, aggressiveness, and inattention) predict illicit drug use independently, or whether their associations with drug use are mediated through cigarette smoking. We used a prospective longitudinal design within theFinnTwin12-17study among Finnish adolescents with baseline at age 12 and follow-up surveys at ages 14 and 17. Path models were conducted withMplusand included 1992 boys and 2123 girls. The outcome was self-reported ever use of cannabis or other illicit drugs at age 17. The predictors were: externalizing behaviors (hyperactivity–impulsivity, aggressiveness, and inattention) assessed by teachers and parents (…
Toma de decisiones gerenciales: una aproximación a través de simulación
2018
RESUMEN Las decisiones gerenciales relacionadas con las inversiones en el desarrollo de recursos estratégicos, constituyen un aspecto clave en la formulación de las estrategias organizativas, y dado el efecto que los recursos estratégicos tienen sobre el desempeño de la firma, se hace pertinente el estudio de este tipo de decisiones, que han sido definidas como una capacidad dinámica gerencial, concepto que se deriva de las capacidades dinámicas de tipo organizativo que permiten a una organización renovar sus competencias cuando son aplicadas, por analogía, a las capacidades de los directivos para gestionar los recursos y competencias organizativos. Al definir este tipo de decisiones como u…
Psychophysical burden and lack of support : Reasons for care workers’ intentions to leave their work in the Nordic countries
2021
Long-term care of older adults is currently suffering from a shortage of trained personnel and high turnover rates. Care work is poorly paid, demanding, increasingly time-bound and both mentally and physically burdensome. In this study, we examined the individual, organisational and economic factors that predict professional care workers’ intentions to leave their current employment, using the NORDCARE survey data (2015, N = 3801) collected in Denmark, Finland, Norway and Sweden. The respondents were mainly practical and assistant nurses. The analysis showed that the predictors of intentions to leave were similar in the four countries. The most consistent organisational predictors of leavin…
Ikä, identiteetti ja ohjaava koulutus. Ikääntyvät pitkäaikaistyöttömät oppimisyhteiskunnan haasteena
2007
Piia Silvennoinen tutki väitöskirjassaan, millainen merkitys työvoimapoliittisella koulutuksella on ikääntyvien pitkäaikaistyöttömien elämässä. Koulutusten oletetaan parantavan ikääntyvien pitkäaikaistyöttömien työmarkkinakelpoisuutta ja elämänhallintaa. Silvennoinen haki vastausta siihen, miten ikääntyvät pitkäaikaistyöttömät itse suhtautuvat työvoimapoliittisiin koulutuksiin; onko niistä heille haittaa vai hyötyä. Silvennoinen kertoo, että koulutuksen hyödyllisyyttä arvioidaan sen työllistävän vaikutuksen kautta. – Mitä vähemmän koulutus työllistää, sitä enemmän myös sen muut merkitykset menettävät arvoaan ikääntyvien pitkäaikaistyöttömien elämässä, Silvennoinen toteaa. Nykyinen itseohjau…
How Followers Differing in Career Motivation Gain Career Profits from Transformational Leaders: A Longitudinal Moderated Mediation Model
2017
Although, transformational leadership is among the most thoroughly examined leadership theories, knowledge regarding its association with followers' career outcomes is still limited. Furthermore, the underlying mechanisms explaining how transformational leaders affect their employees' career success are yet not well-understood. Based on theoretical assumptions about the processes involved in setting the goal of “making a career,” we propose an indirect effect of transformational leadership on subjective and objective career success via development opportunities that depends on the level of career motivation of employees. We conducted a longitudinal study with two measurement occasions separ…

Hsp60 Protects against Amyloid β Oligomer Synaptic Toxicity via Modification of Toxic Oligomer Conformation
2019
Alzheimer's disease (AD) is the leading cause of dementia worldwide. While the etiology of AD remains uncertain, neurotoxic effects of amyloid beta oligomers (Aβo) on synaptic function, a well-established early event in AD, is an attractive area for the development of novel strategies to modify or cease the disease's progression. In this work, we tested the protective action of the mitochondrial chaperone Hsp60 against Aβo neurotoxicity, by determining the direct effect of Hsp60 in changing Aβo toxic conformations and thus reducing their dysfunctional synaptic binding and consequent suppression of long-term potentiation. Our data suggest that Hsp60 has a direct impact on Aβo, resulting in a…
