CelMytB showed optimal activity at 55 A degrees C and pH 6.5, which is similar to the optimal temperature and pH profile of cel5H, an endoglucanase from the closely related S. degradans 2-40. However, the cellulase (degradation of soluble cellulose) and avicelase

(degradation of crystalline cellulose) activities of CelMytB were about 3-fold and 100-fold higher, respectively, than the equivalent activities of cel5H. Moreover, CelMytB could degrade xylan. From the zymogram results, we speculated that the catalytic domain of CelMytB had high activity even without PLX4032 MAPK inhibitor the cellulose binding module. The presence of some detergents stimulated the cellulase activity of CelMytB.”
“Introduction: Given the number of changes that occur during late adolescence, it is possible

that the behavior of asthma may also be different. The aim of our paper is to determine the prevalence of asthma in a population of click here late adolescents and its possible association with obesity, tobacco smoke exposure and family history of allergic disease.\n\nMethods and subjects: In a cross-sectional, population-based analytical study design, we selected a stratified random sample of subjects aged 15 to 18. By modeling risk through logistic regression, we assessed the relationship between asthma and the following covariables: gender, obesity, excess weight, selleck chemicals llc family history of allergic disease and tobacco smoke exposure.\n\nResults: 1,600 subjects were included, and the following prevalences were

identified: asthma 7.8%, obesity 9.6%, active smoking in the father 2 9.8%, active smoking in the mother 18.6% and active smoking habit in the study subjects 15.1%. In the final model, a significant association was found between asthma and the following variables: 1) asthma in the mother (adjusted OR [aOR] 2.95, 95% CI, 1.55 to 5.6); 2) history of allergic rhinitis (aOR = 4.66, 95% CI, 2.63 to 8.25); and 3) male sex (aOR = 1.48, 95% CI, 1.02 to 2.15). No association was seen with obesity or tobacco smoking of the parents.\n\nConclusion: Our results suggest that maternal history of asthma, personal history of.allergic rhinitis and male sex are related with asthma late adolescence, while smoking and being overweight are not.

“The rapid solidification of a peritectic alloy is studied. Various 2D and 3D characterization techniques were effectively utilized to investigate the effect of cooling rate on both the phase fractions and the shrinkage porosity. Particles of Al-36 wt pct Ni were produced using a drop tube impulse system. Neutron diffraction and Rietveld analysis were used to quantify the phases formed during solidification. The microstructure of the produced particles was analyzed using SEM and X-ray microtomography.
