Irreversible tissue damage within the cystic fibrosis (CF) lung is mediated by proteolytic enzymes during an inflammatory response. Serine proteinases, in particular neutrophil elastase (NE), have been implicated however, members of the cysteine proteinase family may also be involved. The aim of this study was to determine cathepsin B and S levels in cystic fibrosis (CF) sputum and to assess any relationship to recognized markers of inflammation such as sputum NE, interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-a), urine TNF receptor 1 (TNFr1), plasma IL-6, and serum C-reactive protein (CRP). Proteinase activities were measured in the sputum of 36 clinically stable CF patients using spectrophotometric and fluorogenic assays. Immunoblots were also used to confirm enzyme activity data. All other parameters were measured by ELISA. Patients had a mean age of 27.2 (8.2) years, FEV. of 1.6 (0.79) L and BMI of 20.7 (2.8). Both cathepsin B and S activities were detected in all samples, with mean concentrations of 18.0 (13.5)?µg/ml and 1.6 (0.88)?µg/ml, respectively and were found to correlate not only with each other but with NE, TNF-a and IL-8 (in all cases .?<?0.05). Airway cathepsin B further correlated with circulatory IL-6 and CRP however, no relationship for either cathepsin was observed with urine TNFr1. This data indicates that cathepsin B and S may have important roles in the pathophysiology of CF lung disease and could have potential as markers of inflammation in future studies. Pediatr.

We study the residential demand for electricity and gas, working with nationwide household-level data that cover recent years, namely 1997-2007. Our dataset is a mixed panel/multi-year cross-sections of dwellings/households in the 50 largest metropolitan areas in the United States as of 2008. We estimate static and dynamic models of electricity and gas demand. We find strong household response to energy prices, both in the short and long term. From the static models, we get estimates of the own price elasticity of electricity demand in the -0.860 to -0.667 range, while the own price elasticity of gas demand is -0.693 to -0.566. These results are robust to a variety of checks. Contrary to earlier literature (Metcalf and Hassett, 1999; Reiss and White, 2005), we find no evidence of significantly different elasticities across households with electric and gas heat. The price elasticity of electricity demand declines with income, but the magnitude of this effect is small. These results are in sharp contrast to much of the literature on residential energy consumption in the United States, and with the figures used in current government agency practice. Our results suggest that there might be greater potential for policies which affect energy price than may have been previously appreciated. (C) 2011 Elsevier B.V. All rights reserved.

The large contemporary French migrant population – estimated by the French Consulate at around 300,000–400,000 in the UK, the majority living in London and the South-East – remains ‘absent’ from studies on migration, and, in a study of migrant food history in Britain, is considered not to have left traces as a migrant community. Over the centuries, the presence of various French communities in London has varied significantly as far as numbers are concerned, but what does not change is their simultaneous ‘visibility’ and ‘invisibility’ in accounts of the history of the capital: even when relatively ‘visible’ at certain historical moments, they still often remain hidden in its histories. At times the French in London are described as a ‘sober, well-behaved […] and law-abiding community’; at other times they ‘appeared as a foreign body in the city’. This article reflects on the dynamics at play between a migrant culture associated with high cultural capital (so much so that is often emulated by those who are not French) and the host culture perception of and relationship to it, in order to consider what this may ‘mean’ for the French (and Francophone) migrant experience. French gastronomy and culinary knowledge is taken as an example of material culture and of cultural capital ‘on display’ specifically in the activity of dining out, especially in French restaurants, or in those influenced by French gastronomy. The social activity of dining out is replete with displays of knowledge (linguistic, culinary), of cultural literacy, of modes of behaviour, of public identity, and of rituals strictly codified in both migrant and host cultures. Dining out is also an emotional and politically-charged activity, fraught with feelings of suspicion (what is in the food? what does the chef get up to in the kitchen?) and of anxieties and tensions concerning status, class and gender distinctions. This article considers the ways in which the migrant French citizen of London may be considered as occupying an ambiguous position at different times in history, simultaneously possessing cultural capital and needing to negotiate complex cultural encounters in the connections between identity and the symbolic status of food in food production, food purveying and food consumption.

Describe las acciones desplegadas por el crucero del B.A.P. Unanue, correspondiente al invierno de 1967, en el que se investigó el área entre el 04º00´s y 17º35´S ocupándose de 168 estaciones de rutina distribuidas en 20 perfiles. Durante todo el recorrido se investigó la presencia de cardúmenes de peces por medio de los equipos de ecosonda y radar y se realizaron observaciones sobre presencia de aves y mamíferos marinos.
