Esteroide anabolizanteak. Goi mailako kirol alorretik gimnasioetara
2013
El presente estudio pretende caracterizar sociológicamente el consumidor recreativo de esteroides anabolizantes en tierras valencianas. La investigación se desarrolla así a partir de la aplicación de una metodología explícitamente cualitativa y la puesta en práctica de la técnica de la entrevista semiestructurada. El perfil sociológico del consumidor recreativo de esteroides anabolizantes se caracteriza por un bajo nivel de estudios, cierta inestabilidad laboral vinculada a menudo con el mundo del ocio nocturno y de la seguridad tanto privada como pública, problemas familiares, gusto por las discotecas y la playa, y frecuentes rupturas en sus relaciones de pareja, entre otros aspectos. Se c…
Modeling cost-effectiveness and health gains of a âuniversalâ versus âprioritizedâ hepatitis C virus treatment policy in a real-life cohort
2017
We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virusâinfected patients: policy 1, âuniversal,â treat all patients, regardless of fibrosis stage; policy 2, treat only âprioritizedâ patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virusâinfected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were us…
IMMAGINAZIONE FILMICA E FANTASCIENZA NELL' EDUCAZIONE DEI GIOVANI
2018
Questo articolo rivaluta l’esperienza filmica come un’occasione di apprendimento per i giovani, nei quali provoca un’immaginazione che permette loro di dotare di nuovi significati la realtà. In particolare, il cinema di fantascienza viene considerato un passaggio imprescindibile per la formazione dell’identità della persona, sia per l’aspetto avventuroso, che conduce gli spettatori ad una graduale metamorfosi da una fase ingenua ad una visione più realistica di se stessi, delle cose e degli altri, sia per la vocazione utopica, cioè per la capacità di immaginare il futuro che fornisce loro un modo per conoscere il presente, recuperare la memoria storica e progettare il futuro.

The brighter side of materialism : Managing impressions on social media for higher social capital
2022
Individuals adjust their behavior on social media to varying extent, and commonly in their idealized way. Most studies have focused on the problems associated with materialism and social media use, yet their potential positive contributions remain less clear. In fact, impression management holds potential for both negative and positive: it has been linked with materialistic attitudes, but also increased amounts of self-reported social capital. This study examines how young people's materialistic values connect with status-seeking impression management on social media, and subsequently to social capital, within the same model. Eight hundred Finnish participants aged 15–19 participated in our…
Effects of menu structure and touch screen scrolling style on the variability of glance durations during in-vehicle visual search tasks.
2011
The effects of alternative navigation device display features on drivers' visual sampling efficiency while searching forpoints of interest were studied in two driving simulation experiments with 40 participants. Given that the number of display items was sufficient, display features that facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations. As predicted, compared with a grid-style menu, searching information in a list-style menu while driving led to smaller variance in durations of in-vehicle glances, in particular with nine item displays. Kinetic touch screen scrolling induced a greater number of very short in-v…
The Adolescent Label Impact Index in a Multicentric Observational Study. Have the Tobacco Advertisements an Impact on the Adolescents?
2020
Background: Pictorial warnings may contribute to lower attractiveness of smoking, particularly among adolescents. The present study compared the impact of two different label styles of tobacco product warnings (textual and pictorial) among adolescents in a new standardized way, using the Adolescent Label Impact Index (ALII). Methods: A school-based cross-sectional study was conducted. Adolescent aged 10–20 years completed an online questionnaire. The ALII score was used to assess the impact of only-textual (ALII-T) and pictorial advertisements (ALII-P). Results: A total of 1,759 students (68.4% response-rate) declared that graphic warnings have a significant impact than textual ones (p <…
Plasma selenium levels and oxidative stress biomarkers: a gene-environment interaction population-based study.
2014
The role of selenium exposure in preventing chronic disease is controversial, especially in selenium-repleted populations. At high concentrations, selenium exposure may increase oxidative stress. Studies evaluating the interaction of genetic variation in genes involved in oxidative stress pathways and selenium are scarce. We evaluated the cross-sectional association of plasma selenium concentrations with oxidative stress levels, measured as oxidized to reduced glutathione ratio (GSSG/GSH), malondialdehyde (MDA), and 8-oxo-7,8-dihydroguanine (8-oxo-dG) in urine, and the interacting role of genetic variation in oxidative stress candidate genes, in a representative sample of 1445 men and women…
Comparative effectiveness of helicopter emergency medical services compared to ground emergency medical services
2013
Physician-staffed helicopter emergency medical services (HEMS) are a well-established component of prehospital trauma care in Germany. Reduced rescue times and increased catchment area represent presumable specific advantages of HEMS. In contrast, the availability of HEMS is connected to a high financial burden and depends on the weather, day time and controlled visual flight rules. To date, clear evidence regarding the beneficial effects of HEMS in terms of improved clinical outcome has remained elusive.Traumatized patients (Injury Severity Score; ISS≥9) primarily treated by HEMS or ground emergency medical services (GEMS) between 2007 and 2009 were analyzed using the TraumaRegister DGU® o…
Association of military training with oxidative stress and overreaching.
2011
ABSTRACT: We hypothesized that increased oxidative stress and disrupted redox balance may be predisposing factors and markers for overreaching (OR). Purpose: The study's purpose was to examine whether oxidative stress markers and antioxidant status and physical fitness are related to OR during an 8-wk military basic training (BT) period. Methods: Oxidative stress and antioxidant status were evaluated in the beginning and after 4 and 7 wk of training in 35 males (age = 19.7 ± 0.3 yr) at rest and immediately after a 45-min submaximal exercise. Physical activity (PA) was monitored by an accelerometer throughout BT. Indicators of OR were also examined. Results: From baseline to week 4, increase…
On the correlation between mechanical and TEM studies of the aging of palladium during tritium storage
2005
Abstract Tritium has considerable technological applications in nuclear industry. Since it is a radioactive element, its storage is often considered in the form of tritides which ensure the required safety. However, the decay of tritium into 3 He alters the tritide properties during aging. With the aim of understanding the aging mechanisms of palladium tritide, a macroscale approach coupled with a microscopic study was performed on palladium aged up to eight months after tritium loading. The macroscale investigation based on the vibration of microcantilevers allowed the mechanical response of the material to be followed during its aging. The microscopic study was performed by Transmission E…
