Efecto de la salazón en seco sobre el perfil de flavonoides y la capacidad antioxidante de cultivares Argelinos. En este estudio se investigó los cambios en el perfil de flavonoides y la capacidad antioxidante de cinco cultivares de olivo después de una salazón en seco. La actividad antioxidante se determinó mediante los métodos FRAP (Ferric ion Reducing Antioxidant Power), ORAC (capacidad de absorción de radicales de oxígeno) y ensayos de blanqueo de β-caroteno. Los resultados mostraron que los efectos de la salazón en seco en los parámetros analizados fueron significativos (P<0,05). Esto causó una disminución en los flavonoides totales con una tasa de pérdida del 55%. El análisis por HPLC de los extractos reveló la presencia de cuatro flavonoides: rutina, luteolina-7-glucósido, cianidina-3-glucósido y cianidina-3-rutinósido. Entre los cultivares estudiados, Azeradj se caracteriza por altos niveles de flavonoides. En cuanto a la actividad antioxidante, se obtuvieron resultados divergentes utilizando diferentes ensayos antioxidantes. En general, la salazón en seco indujo una reducción en la actividad.

This study aimed to evaluate differences between low active overweight and obese children in terms of energy expenditure (EE), ventilation (VE), and cardiac response during graded submaximal treadmill testing at constant speed. Methods: We categorized 20 children into two weight groups according to the International Obesity Task Force criteria: overweight (n=10; age=9.7 ±1.34 years) and obese (n=10; age=10.4±1.4 years). Children performed treadmill testing at a constant speed (1.53 m·s-1 ) and increasing grade (0%, 4%, and 8%). every 3 min. Results: The EE across all grades was significantly higher (p<0.001) in obese than in overweight children. Differences at each grade disappeared when EE was adjusted by body mass; however, several differences remained when the EE was adjusted by fat-free mass or body surface area. The increase in EE with increasing grade was greater in obese children (effect size between 0% and 8% for EE was 1.17). BMI z-score and fat mass (kg) were the main predictors of EE (Kcal·min-1 ) and contributed to explaining 66%, 70% and 83.4% of the variance in EE at 0%, 4% and 8% gradients respectively. Conclusion: We suggest that when assessing EE response to exercise, the degree of obesity should be taken into consideration.

Emphatic reciprocal expressions and symmetric verbs in spanish: an empirical analysis

  • Vázquez García, Glòria
  • Fernández Montraveta, Ana María
In this paper we present a descriptive study on the compatibility of emphatic reciprocal expressions with Spanish lexical reciprocal (or symmetric) verbs. Since lexical reciprocal verbs express reciprocity intrinsically, they should not require the use of an emphatic reciprocal expression to denote reciprocal meaning. Some scholars even claim that some emphatic reciprocal expressions, such as mutuamente, are incompatible. The aim of this paper is to describe to what extent symmetric verbs can be used with four of these expressions using an empirical approach. The results obtained shed light to the questions raised: we have been able to verify that these expressions are more frequent with non-reciprocal verbs and we have proved that the combination of symmetric verbs with all these expressions is possible, even in the case of mutuamente.
