Evaluation of a sampling strategy for estimation of long-term PM2.5 exposure for epidemiological studies (Publications)
As part of the European Community Respiratory Health Survey (ECRHS) PM2.5 (particles collected with an upper 50% cut point of 2.5 microm aerodynamic diameter) was measured using an EPA-WINS (Environmental [...] the 'true' long-term averages, which were estimated using all available daily means. The daily PM2.5 means, obtained by both instruments operated in parallel, were only slightly different (the mean difference
Levels of physical activity and sedentary time among 10- to 12-year-old boys and girls across 5 European countries using accelerometers: an... (Publications)
ABSTRACT: BACKGROUND: The study aim was to objectively assess levels of sedentary time, light, moderate and vigorous physical activity (PA) among 10-12 year olds across five European countries and to
Source apportionment of ambient PM2.5 at five spanish centres of the european community respiratory health survey (ECRHS II) (Publications)
clearly observed in PM2.5. Multi-linear regression analysis (MLRA) was applied to the data, showing that traffic was the main source of PM2.5 at the five sites (39-53% of PM2.5, 5.1-12.0 mgm [...] particulate matter (PM2.5) was sampled at 5 Spanish locations during the European Community Respiratory Health Survey II (ECRHS II). In an attempt to identify and quantify PM2.5 sources, source contribution [...] analysis (PCA) was performed on five datasets containing elemental composition of PM2.5...
The activity of diguanidino and 'reversed' diamidino 2,5-diarylfurans versus <em>Trypanosoma cruzi</em> and <em>Leishmania donovani</em> (Publications)
The in vitro activity of 20 dicationic molecules containing either diguanidino or reversed amidine cationic groups were evaluated versus Trypanosoma cruzi and Leishmania donovani. The most active comp

We studied relationships between patients' clinical characteristics [...] CD27, the resolution of CD38 expression by antigen-specific T cells was observed readily following 5 months of antibiotic therapy. However, the intensity of CD38-TAM signals measured at diagnosis did not

between wildfire-related PM2.5 and mortality has not been well characterised. We aimed to comprehensively assess the association between short-term exposure to wildfire-related PM2.5 and mortality across various [...] wildfire-related PM2.5 were estimated using the three-dimensional chemical transport model GEOS-Chem at a 0.25 degrees x 0.25 degrees resolution. The association between wildfire-related PM2.5 exposure and mortality [...] attributable to the acute impacts of wildfire-related PM2.5...
Long-term exposures to PM2.5, black carbon and NO2 and prevalence of current rhinitis in French adults: the constances cohort (Publications)
BACKGROUND: Rhinitis is one of the most common disease worldwide with a high and increasing prevalence. There is limited knowledge on the link between long-term exposure to air pollution and rhinitis.
Differential mortality risks associated with PM2.5 components: a multi-country, multi-city study (Publications)
BACKGROUND: The association between fine particulate matter (PM2.5) and mortality widely differs between as well as within countries. Differences in PM2.5 composition can play a role in modifying the effect estimates [...] daily total PM2.5 through time series regression analysis. We then pooled these estimates in a meta-regression model that included city-specific logratio-transformed proportions of seven PM2.5 components as [...] heterogeneity in PM2.5 risk. CONCLUSIONS: These findings...
