Plasma redox response of Sicilian Opuntia Ficus Indica juice in young physically active women.
2017
It is known amateur female athletes show an altered redox status [1] and the consumption of Opuntia Ficus Indica (OFI) decreases oxidative stress (OS) in healthy humans [2]. Therefore, the aim of this study was to investigate whether the supplementation with Sicilian OFI juice affected plasma redox balance following a maximal effort test in young physically active women . This study was randomized, double blind, placebo controlled and crossover design. Eight women (23.25±2.95 years old, weight of 54.13±9.05 kg, height of 157.75±0.66 cm and BMI of 21.69±0.66 kg/m2) were randomly divided into 2 groups and each group was supplied with either 50 ml OFI, diluted to 170 ml with water, or 170 ml …
Moderate overexpression of glucose-6-phosphate dehydrogenase improves healthspan in mice. Implications in skeletal muscle regeneration
2019
An enormous increment in the average lifespan of diverse populations occurred worldwide in the 20th century. In the last 10–15 years, the importance has changed from extending average and even maximal longevity to favoring healthy aging, and many researchers have focused their studies on the aim at extending healthspan. Prolonging lifespan without taking care of improving healthspan can derive in a long time of living with disabilities and constitutes a risk factor for the old population to suffer a higher prevalence of aging-related diseases. Indeed, modern disease treatments frequently diminish mortality without any effect on the deterioration of overall health. Understanding the mechanis…
Affect self-regulation through music
2018
The present dissertation focused on musical affect regulation, i.e. on the use of music to self-regulate affective states such as emotions, moods, and energy levels. In publication I, relevant findings from previous research were extracted and the field’s conceptual clarity and precision was assessed. Besides identifying weaknesses in conceptualization and providing recommendations for future studies, publication I found that not all the elements of affect regulation through music have been equally explored by research. Given the gap observed on the study of musical mechanisms underlying affect regulation, publication II placed a special focus on this component and its association with regu…
Validation of a Shear Model for RC and Hybrid Beams with Two Different Inclinations of Transversal Reinforcement
2016
The validation of an analytical model recently proposed for evaluation of the shear capacity in Reinforced Concrete (RC) beams containing multiple inclination of transverse stirrups is presented. The model is a suitable extension of that currently proposed in Eurocode 2 for the evaluation of the shear resistance, and it is derived by means of the the variable-inclination stressfield theory based on Nielsen’s plastic approach. Experimental and numerical data available in the literature on Hybrid Steel-Trussed Concrete Beams (HSTCBs) are used for model validation and result discussion. Finally, also the comparison with a different analytical approach for the assessment of the shear resistance…
A Path Model for Subjective Well-Being during the Second Wave of the COVID-19 Pandemic: A Comparative Study among Polish and Ukrainian University Stu…
2022
Background: Previous studies showed several associations between physical and mental health dimensions and well-being. This study aims to examine a complex path model explaining the life satisfaction of university students from Poland and Ukraine during the second wave of the COVID-19 pandemic. Methods: The cross-sectional web-based study was performed in November 2020 using Google Forms. The conventional sample of 3230 university students from Poland (n = 1581) and Ukraine (n = 1649), aged 18–59 (M = 21.40, SD = 3.46), with 59% women, participated in the study. We used standardized questionnaires to measure life satisfaction (SWLS), self-reported physical health (GSRH), perceived stress (P…
Bifactor analysis and construct validity of the five facet mindfulness questionnaire (FFMQ) in non-clinical Spanish samples
2015
The objective of the present study was to examine the dimensionality, reliability, and construct validity of the Five Facet Mindfulness Questionnaire (FFMQ) in three Spanish samples using structural equation modeling (SEM). Pooling the FFMQ data from 3 Spanish samples (n = 1191), we estimated the fit of two competing models (correlated five-factor vs. bifactor) via confirmatory factor analysis. The factorial invariance of the best fitting model across meditative practice was also addressed. The pattern of relationships between the FFMQ latent dimensions and anxiety, depression, and distress was analyzed using SEM. FFMQ reliability was examined by computing the omega and omega hierarchical c…

Dynamics of hydrofracturing and permeability evolution in layered reservoirs
2015
International audience; A coupled hydro-mechanical model is presented to model fluid driven fracturing in layered porous rocks. In the model the solid elastic continuum is described by a discrete element approach coupled with a fluid continuum grid that is used to solve Darcy based pressure diffusion. The model assumes poro-elasto-plastic effects and yields real time dynamic aspects of the fracturing and effective stress evolution under the influence of excess fluid pressure gradients. We show that the formation and propagation of hydrofractures are sensitive to mechanical and tectonic conditions of the system. In cases where elevated fluid pressure is the sole driving agent in a stable tec…
Sotilaan fyysisen toimintakyvyn tutkimus vuosilta 2005–2020 yksissä kansissa
2022
Sotilaan fyysisen toimintakyvyn tutkimustoiminta aloitettiin Puolustusvoimissa laajamittaisesti vuoden 2005 alusta, jolloin tässä artikkelissa kuvatun teoksen edeltäjä, Taistelija 2005, julkaistiin. Sitä ennen tutkimus oli ollut sirpaleista ja vailla suunnitelmallisuutta. Tutkimusta on tehty yhteistyössä ulkopuolisten tutkimuslaitosten, kuten Jyväskylän yliopiston, Työterveyslaitoksen ja UKK-instituutin, kanssa. Puolustusvoimissa keskeisiä toimijoita ovat olleet Pääesikunnan koulutusosasto, Maanpuolustuskorkeakoulu, Sotilaslääketieteen keskus ja Puolustusvoimien tutkimuslaitos. Tässä artikkelissa kuvataan lyhyesti sotilaan fyysisen toimintakyvyn tutkimusta vuosilta 2005–2020. Aiheeseen liit…
Differential associations of leisure music engagement with resilience : A network analysis
2023
Background/Objective Several factors associated with resilience as the maintenance of mental health despite stress exposure can be strengthened through participation in leisure time activities. Since many people listen to or make music in their leisure time, the aim of the present study was to provide insights into the architecture of how resilience relates to passive and active music engagement. Method 511 participants regularly listening to and/or making music completed an online survey on resilient outcomes (i.e., mental health and stressor recovery ability), different resilience factors (e.g., optimism, social support), quantitative music engagement (i.e., time spent with music listenin…
