Validation of the Portuguese Version of the Healthy Lifestyle Questionnaire

The main objective of this study was the validation of the Healthy Lifestyle Questionnaire (EVS II), using a confirmatory factorial analysis of the measurement model, with veteran athletes. A total of 348 veteran Portuguese athletes of both genders, aged between 30 and 60 years (M = 41.64, SD = 9.83), of whom 200 were males and 148 were females, from several sports. The results of the confirmatory factor analysis demonstrate the adequacy of the adapted version of the EVS II, as the factorial structure (6 factors/24 items) has acceptable validity indexes: χ2 = 305.925, p = 0.000, df = 120.017, χ2/df = 2.549, NFI (Normed Fit Index) = 0.909, TLI (Tucker Lewis Index) = 0.918, CFI (Comparative Fit Index) = 0.944, GFI (Goodness of Fit Index) = 0.944, AGFI (Adjusted Goodness of Fit Index) = 0.909, SRMR (Standardized Root Mean Square Residual) = 0.048, RMSEA (Root Mean Square of Approximation) = 0.060, allowing evaluation of the dimensions of balanced diet, respect for mealtime, tobacco and alcohol consumption, other drugs consumption and resting habits. The adaptation to sport of the Portuguese version of EVS II can be used with reasonable confidence in the evaluation of healthy lifestyles in the context of sportinfo:eu-repo/semantics/publishedVersio

Transcontextual model application in the prediction of veteran judo athletes’ life satisfaction

Background and Study Aim: Despite recognised benefits of regular physical activity for health, the percentage of individuals linking with a physical activity practice sufficient to confer health benefits is low. The aim of current work is knowledge about effects of an extension of the motivation trans-contextual model application, specifically in the prediction of life satisfaction by veteran judo athletes. Material and Methods: It was used a sample of 99 Portuguese veteran judo athletes of both genders, aged between 30 and 76 years (M = 42.61 ±9.75), where through questionnaires were measured: basic psychological needs satisfaction, motivation, planned behaviour variables and life satisfaction. Results: The structural equations model showed that autonomy perception positively and significantly predicts autonomous motivation. In its turn it positively and significantly predicts intentions. Conclusions: Life satisfaction is positively and significantly predicted by intentions. Results authorise to emphasise the importance of fostering autonomy, since this will favour autonomous motivation, promoting a higher behavioural control over the practitioners’ intentions, thus generating a higher life satisfaction.info:eu-repo/semantics/publishedVersio

Effect of hyperthyroidism on circulating prolactin and hypothalamic expression of tyrosine hydroxylase, prolactin signaling cascade members and estrogen and progesterone receptors during late pregnancy and lactation in the rat

Hyperthyroidism (HyperT) compromises pregnancy and lactation, hindering suckling-induced PRL release. We studied the effect of HyperT on hypothalamic mRNA (RT-qPCR) and protein (Western blot) expression of tyrosine hydroxylase (TH), PRL receptor (PRLR) and signaling pathway members, estrogen-α (ERα) and progesterone (PR) receptors on late pregnancy (days G19, 20 and 21) and early lactation (L2) in rats. HyperT advanced pre-partum PRL release, reduced circulating PRL on L2 and increased TH mRNA (G21 and L2), p-TH, PRLR mRNA, STAT5 protein (G19 and L2), PRLR protein (G21) and CIS protein (G19). PRs mRNAs and protein decreased on G19 but afterwards PRA mRNA (G20), PRB mRNA (G21) and PRA mRNA and protein (L2) increased. ERα protein increased on G19 and decreased on G20. Thus, the altered hypothalamic PRLR, STAT5, PR and ERα expression in hyperthyroid rats may induce elevated TH expression and activation, that consequently, elevate dopaminergic tone during lactation, blunting suckling-induced PRL release and litter growth.Fil: Pennacchio, Gisela Erika.

Splenogonadal fusion and sex reversal

Splenogonadal fusion is a rare congenital malformation where an abnormal union occurs between the spleen and gonad or mesonephric derivatives. Although it occurs in females it is much less prevalent than in males (male:female ratio, 16:1), but this may partly be because of the inaccessibility of the female gonads leading to under-diagnosis. To our knowledge this is the first case of splenogonadal fusion associated with sex reversal reported in the literature

Multiple sex chromosome systems in howler monkeys (Platyrrhini, Alouatta)

In light of the multiple sex chromosome systems observed in howler monkeys (Alouatta Lacépède, 1799) a combined cladistic analysis using chromosomal and molecular characters was applied to discuss the possible origin of these systems. Mesoamerican and South American howlers were karyologically compared. FISH analysis using the chromosome painting probes for the #3 and #15 human chromosomes was applied to corroborate the homeology of the sexual systems. We found that the HSA3/15 syntenic association, present in the sex chromosome systems of South American Howlers, is not present in those of Mesoamerican ones. The autosomes involved in the translocation that formed the sexual systems in the Mesoamerican and South American species are different, thus suggesting an independent origin. Parsimony analysis resolved the phylogenetic relationships among howler species, demonstrating utility of the combined approach. A hypothesis for the origin of the multiple sex chromosome systems for the genus is proposed.Fil: Steinberg, Eliana Ruth. Consejo Nacional de Investigaciones Científicas y Técnicas.

Uses of the smartphone in current journalism. towards a new media model? case study of the context of malaga

En los últimos años, el avance de la tecnología está introduciendo transformaciones significativas en el sistema mediático tradicional. La penetración de los smartphones y el uso masivo de los mismos para el consumo informativo obliga a los medios de comunicación a actualizarse y adaptarse a la nueva realidad social. Ubicuidad, inmediatez e interactividad son, hoy en día, las características predominantes de la producción, difusión y consumo de contenidos mediáticos. Las noticias móviles están ganando una importancia crucial para los medios tradicionales (Westlund, 2013) y los profesionales de la información deben afrontar el ajuste de sus rutinas productivas a este nuevo escenario. La presente investigación, tomando como estudio de caso el entorno mediático malagueño, se propone conocer la forma en la que los periodistas, así como las empresas de medios, se adaptan al uso de la denominada “cuarta pantalla” (Aguado y Martínez, 2008; Miller, 2014) de los Smartphone o teléfonos inteligentes, unos dispositivos considerados ya como el “metamedio del siglo XXI” (Márquez, 2017). Para ello se emplea la entrevista en profundidad como metodología cualitativa-descriptiva junto a la observación participante, dada la condición de redactora, en los servicios informativos de PTV Málaga, de una de las autoras del texto. Los resultados evidencian la polivalencia (González, 2013) como un factor prominente entre los periodistas locales que, a diario, emplean el Smartphone en sus rutinas productivas. La investigación concluye que, en el ámbito local, aunque con excepciones, las empresas mediáticas tienden a aprovechar las potencialidades que actualmente ofrecen los teléfonos inteligentes.In recent years, the advancement of technology is introducing significant transformations in the traditional media system. The penetration of Smartphones, and the massive use of them for informative consumption, forces the media to update and adapt to the new social reality. Ubiquity, immediacy and interactivity are, nowadays, the predominant characteristics of the production, diffusion and consumption of media content. Mobile news is gaining crucial importance for traditional media (Westlund, 2013) and information professionals must confront the adjustment of their productive routines to this new scenario. The present investigation, taking as a case study the media environment of Malaga, proposes to know the way in which journalists, as well as media companies, adapt to the use of the so-called “fourth screen” (Aguado and Martínez, 2008; Miller, 2014) of smartphones, some devices already considered the “metamedia of the 21st century” (Márquez, 2017). For this, the in-depth interview is used as a qualitative-descriptive methodology together with the participant observation, given the condition of editor, in the information services of PTV Málaga, by one of the authors of the text. The results show the versatility (González, 2013) as a prominent factor among local journalists, who daily use Smartphones in their productive routines. The research concludes that, at the local level, although with exceptions, media companies tend to take advantage of the potentials that smartphones currentlyoffer

The El Masnou Infralittoral sedimentary environment (Barcelona province, NW Mediterranean Sea): morphology and Holocene seismic stratigraphy

A detailed analysis of the morphology and the Holocene seismic and sequence stratigraphy and architecture of the infralittoral sedimentary environment of the El Masnou coast (Catalonia, NW Mediterranean Sea) was carried out using multibeam bathymetry and GeoPulse seismic data. This environment extends down to 26-30 m water depth, and is defined morphologically by two depositional wedges whose seafloor is affected by erosive furrows, slides, fields of large- and small-scale wavy bedforms, and dredging trenches and pits. Erosive terraces are also identified in the transition domain toward the inner continental shelf. The Holocene stratigraphy of the infralittoral environment is defined by two major seismic sequences (lower and upper), each one formed by internal seismic units. The sequences and units are characterised by downlapping surfaces made up of deposits formed by progradation of coastal lithosomes. The stratigraphy and stratal architecture, displaying a retrogradational arrangement with progradational patterns of minor order, were controlled by different sea-level positions. The stratigraphic division represents the coastal response to the last fourth-order transgressive and highstand conditions, modulated by small-scale sea-level oscillations (≈1-2 m) of fith to sixth order. This study also highlights the advantage of an integrated analysis using acoustic/seismic methods for practical assessment of the anthropogenic effects on infralittoral domains based on the association of marine geological observations
