Caracterización biológica y de compuestos derivados del petróleo de la zona de Perdido para establecer las condiciones de los bioensayos y experimentos de mesocosmos.
No full textEl documento se divide en tres partes principales. La primera parte se avoca a la caracterización de la biota de la columna de agua y del sedimento, enfatizando la diversidad y distribución de especies. Esta primera sección permitió establecer los criterios de selección de los organismos y comunidades a ser sometidos a los experimentos de bioensayos y mesocosmos. La segunda parte se centró en la caracterización de los compuestos derivados del petróleo en la columna de agua y tejidos, así como la caracterización química del petróleo utilizado en los experimentos de bioensayos y mesocosmos. Con esta información se logró establecer las concentraciones de petróleo a ser utilizadas en los experimentos de exposición. La tercera parte describe los protocolos experimentales para evaluar el efecto directo del petróleo sobre la salud de los peces, sus parásitos y sobre la comunidad del fitoplancton.Citar como: Pech, D., Vidal-Martínez V.M., Herrera-Silveira, J.A., Aguirre-Macedo M.L.

Normocaloric diet improves asthma-related quality of life in obese pubertal adolescents
No full textBackground: Restrictive, very low-energy diets focused on rapid weight loss have proven to be effective in improving asthma outcome in obese patients, but their use in children and pubescents is controversial due its potential consequences in growth. More conservative, normocaloric schemes are suggested as a more suitable dietary approach for these patients. Methods: A randomized clinical trial was run of 51 pubertal adolescents with asthma and obesity, who were allocated to either an interventional 28-week program of normocaloric diet based on normal requirements for height and meal planning (n = 26) or a non-interventional (free diet) control group (n = 25). Asthma-related quality of life (AR-QOL, assessed by the Standardized Pediatric Asthma Quality of Life Questionnaire, PAQLQ[S]) and clinical indicators of asthma control were measured before and after the intervention period. Results: Diet intervention was associated with a significant improvement in AR-QOL in relation to baseline (? PAQLQ[S] scores) compared with controls, both in overall score (p < 0.001) and its subdomains (activity limitation, p < 0.001; symptoms, p < 0.002; emotional function, p < 0.001). The group with normocaloric diet observed a significant decrease in body mass index z-score, which correlated positively with the improvement in AR-QOL (Spearman's r = 0.51, p < 0.01), in addition to have significantly fewer events of acute attacks of asthma and nighttime awakenings, plus a non-significant reduction in the use of inhaled corticosteroids. No significant changes were observed in the pulmonary function tests. Conclusion: The normocaloric dietary intervention was associated with improvement of AR-QOL and some aspects of asthma control. Such structured dietary programs could probably have a role as a complementary non-pharmacological therapeutic strategy in obese pubertal adolescents with asthma. � 2014 S. Karger AG, Basel

A global scale mechanistic model of photosynthetic capacity (LUNA V1.0)
No full textAlthough plant photosynthetic capacity as determined by the maximum
carboxylation rate (i.e., Vc, max25) and the maximum electron transport
rate (i.e., Jmax25) at a reference temperature (generally 25 °C) is
known to vary considerably in space and time in response to environmental
conditions, it is typically parameterized in Earth system models (ESMs) with
tabulated values associated with plant functional types. In this study, we
have developed a mechanistic model of leaf utilization of nitrogen for
assimilation (LUNA) to predict photosynthetic capacity at the
global scale under different environmental conditions. We adopt an
optimality hypothesis to nitrogen allocation among light capture, electron
transport, carboxylation and respiration. The LUNA model is able to
reasonably capture the measured spatial and temporal patterns of
photosynthetic capacity as it explains ∼ 55 % of the global
variation in observed values of Vc, max25 and ∼ 65 % of the variation in the observed values of Jmax25. Model
simulations with LUNA under current and future climate conditions
demonstrate that modeled values of Vc, max25 are most affected in
high-latitude regions under future climates. ESMs that relate the values of
Vc, max25 or Jmax25 to plant functional types only are likely to
substantially overestimate future global photosynthesis
Climacteric fruit ripening: Ethylene-dependent and independent regulation of ripening pathways in melon fruit
No full textCantaloupe melons have a typical climacteric behaviour with ethylene playing a major role in the regulation of the ripening process and affecting the ripening rate. Crossing of Cantaloupe Charentais melon with a non-climacteric melon indicated that the climacteric character is genetically dominant and conferred by two duplicated loci only. However, other experiments made by crossing two non-climacteric melons have generated climacteric fruit, indicating that different and complex genetic regulation exists for the climacteric character. Suppression of ethylene production by antisense ACC oxidase RNA in Charentais melon has shown that, while many ripening pathways were regulated by ethylene (synthesis of aroma volatiles, respiratory climacteric and degreening of the rind), some were ethylene-independent (initiation of climacteric, sugar accumulation, loss of acidity and coloration of the pulp). Softening of the flesh comprised both ethylene-dependent and independent components that were correlated with differential regulation of cell wall degrading genes. These results indicate that climacteric (ethylene-dependent) and non-climacteric (ethylene-independent) regulation coexist during climacteric fruit ripening. In addition, ethylenesuppressed melons allowed demonstrating that the various ethylene-dependent events exhibited differential sensitivity to ethylene and that ethylene was promoting sensitivity to chilling injury. Throughout this review, the data generated with melon are compared with those obtained with tomato and other fruit
