Motivación al deporte en adultos y personas mayores que practican cachibol

Con el propósito de comprender la motivación en un grupo de adultos y personas mayores practican cachibol y los factores para continuar o desertar en la práctica de este deporte, se realizó un estudio con diseño descriptivo, transversal y exploratorio. Para tal n, se diseñó un instrumen- to denominado Escala de Motivación en el Deporte para Personas Mayores (EMDPM), fundamentado teóricamente para medir los motivos de inicio, continuidad y desmotivación, inicialmente en la práctica deportiva de per- sonas mayores. Se encontró que la motivación más importante se centra en la salud y entre los factores de desmotivación destacan los relacionados con la enfermedad y las lesiones.

Predicting non-invasive ventilation failure in children from the SpO₂/FiO₂ (SF) ratio

PURPOSE: Our objective was to assess whether SpO₂/FiO₂ (SF) ratio could be a useful NIV outcome predictor in children with acute respiratory failure (ARF) and tried to develop a predictive model of NIV failure. METHODS: Prospective, observational, multicenter study. Episodes of ARF-fulfilling inclusion criteria from 15 January 2010 to 14 January 2011 were treated with NIV according to a pre-established protocol. Clinical variables were collected at baseline and at 1, 2, 6, 12 and 24 h. Failure criterion was the need for endotracheal intubation. Failures were considered as "early" if occurring ≤6 h after NIV initiation, "intermediate" if occurring between 6 and 24 h, and "late" if occurring after 24 h. Variables with a p < 0.1 in univariate analysis corrected by age were included in multivariate analysis. Models were calculated based on multivariate analysis. RESULTS: During the study period, 390 episodes were included. NIV success rate was 81.3 %. Among ARF causes, failure occurred most frequently in ARDS episodes. The failure predictive model for the whole sample included SF ratio at 1 h, age and PRISM III-24 (area under the curve AUC of 0.755). For early NIV failures, SF ratio at 1 h was the only variable within model (AUC 0.748). The analysis of intermediate NIV failures identified 3 variables independently linked to NIV outcome: PRISM III-24, RR decrease at 6 h, and SF ratio at 6 h (AUC 0.895). No model was identified for late NIV failure. CONCLUSIONS: SF ratio is a reliable predictor of early NIV failure in children

Impact of Human Management on the Genetic Variation of Wild Pepper, Capsicum annuum var. glabriusculum

Management of wild peppers in Mexico has occurred for a long time without clear phenotypic signs of domestication. However, pre-domestication management could have implications for the population's genetic richness. To test this hypothesis we analysed 27 wild (W), let standing (LS) and cultivated (C) populations, plus 7 samples from local markets (LM), with nine polymorphic microsatellite markers. Two hundred and fifty two alleles were identified, averaging 28 per locus. Allele number was higher in W, and 15 and 40% less in LS and C populations, respectively. Genetic variation had a significant population structure. In W populations, structure was associated with ecological and geographic areas according to isolation by distance. When LM and C populations where included in the analysis, differentiation was no longer apparent. Most LM were related to distant populations from Sierra Madre Oriental, which represents their probable origin. Historical demography shows a recent decline in all W populations. Thus, pre-domestication human management is associated with a significant reduction of genetic diversity and with a loss of differentiation suggesting movement among regions by man. Measures to conserve wild and managed populations should be implemented to maintain the source and the architecture of genetic variation in this important crop relative

Motivação ao esporte em adultos e idosos que praticam cachibol

Test (EMDPM) which measures based theoretically practical reasons, factors of motivation and demotivation in practice Cachibol was built in older adults. Te reasons and factors are most important motivation aimed at health and demotivating the most important are those related to the loss of health.RESUMO: É um estudo exploratório com pesquisa e desenho descritivo transversal, cujos objetivos são: Conhecer os motivos pelos quais as pessoas escolhem praticar idosos Cachibol; Quais são os fatores que os motivam a continuar a prática; Quais os fatores que os desencorajam na prática. Teste (EMDPM) que mede razões teóricamente práticas, fatores de motivação e desmotivação na prática, Cachibol foi construído em adultos mais velhos. As razões e os fatores são motivações mais importantes para a saúde e a desmotivação dos mais importantes são as relacionadas à perda de saúde

Enzimas antioxidantes en la maduración de carne de vacuno procedente de dos cabañas autóctonas asturianas

Antioxidant enzymes throughout ageing from two local cattle breeds In this study, meat from double-muscled (“culones”, mh/mh) and normal (+/+) young bulls of the breed Asturiana de los Valles (AV) as well as normal (+/+) animals from Asturiana de la Montaña (AM) was analysed during ageing at 4°C with regard to its oxidative status. Activities of the following main antioxidant enzymes were determined: Superoxide dismutase (SOD), Catalase (CAT) and Glutathione reductase (GR). In both breeds (AV and AM), lipid peroxidation (LPO) was also measured throughout the ageing period, because meat shelf life is mainly limited by lipids and proteins. All enzymes were apparently stable during meat ageing. While GR exhibited the lowest activity among antioxidant enzymes, SOD and CAT showed activity along the ageing period studied, with similar activity pattern seen in both double-muscled and normal animals, although, being advanced in the formers. In normal animals of both the AV and AM breeds, lipid peroxidation did not vary during ageing. However, double- muscled meat showed a significant increase after 7 days of maturation.En este trabajo se determinó el estado oxidativo de la carne procedente de terneros añojos de genotipo culón (mh/mh) y normal (+/+) de la raza Asturiana de los Valles (AV) así como terneros normales (+/+) de la raza Asturiana de la Montaña (AM) durante su periodo de maduración a 4ºC, mediante el estudio de la actividad de los principales enzimas antioxidantes: Superóxido dismutasa (SOD), Catalasa (CAT) y Glutatión reductasa (GR). Se midió también el nivel de peroxidación lipídica (LPO) a lo largo de la maduración a 4ºC de carne procedente de ambas razas (AV y AM) por ser los lípidos y las proteínas las biomoléculas que más limitan la vida media de la carne durante este periodo. Los resultados reflejaron una clara estabilidad de los enzimas durante el periodo de maduración de la carne, siendo el enzima GR el que mostró menor actividad, mientras que SOD y CAT presentaron actividad a lo largo de todo el período de maduración estudiado con un patrón de actividad que se repitió en la carne de terneros (mh/mh) y (+/+) de raza AV, siendo más adelantado en los primeros que en los segundos. La peroxidación lipídica no mostró variación alguna a lo largo de la maduración tanto en animales (+/+) de la raza AV como en animales (+/+) de la raza AM. Sin embargo, los animales (mh/mh) de la raza AV mostraron un incremento significativo del daño lipídico en el músculo tras 7 días de maduración
