Spatial variation of PM elemental compositon between and within 20 European study areas - results of the ESCAPE project (Publications)
from 0.90 (V) to 1.60 (Cu) for PM2.5 and from 0.93 (V) to 2.28 (Cu) for PM10. Our selected PM elements were variably correlated with the main pollutants (PM2.5, PM10, PM2.5 absorbance, NO2 and NOx) across [...] coarse fractions were modestly correlated (between 0.5 and 0.75); and the remaining elements in the various size fractions had lower correlations (around 0.5 or below). This variability in correlation demonstrated [...] However, we lack comprehensive data on the spatial distribution of...

lactones (STL) of the xanthanolide series (4,5-seco-guaianolide-type). They were identified by spectroscopic means as 8-epixanthatin ( 1), 8-epixanthatin 1beta,5beta-epoxide ( 2), and as the dimers pungiolide [...] pungiolide A ( 4) as well as pungiolide B ( 5). Two further modified xanthanolide sesquiterpene lactones, xanthipungolide ( 3) and 4,15-dinor-1,11(13)-xanthadiene-3,5beta:12,8beta-diolide ( 6) were isolated [...] single compound from this extract, 8-epixanthatin 1beta,5beta-epoxide...
Tick species from cattle in the Adama Region of Ethiopia and pathogens detected (Publications)

Among all ticks, 32 (11%) were positive for Rickettsia spp. and 15 (5.2%) of these were identified [...] variegatum (n = 10) and A. cohaerens (n = 5). The remainder of Rickettsia-positive samples could not be amplified due to low DNA yield. Furthermore, another 15 (5.2%) samples carried other pathogenic bacteria: [...] PCR. Species identification was done by phylogenetic analysis...
Long-term exposure to ambient air pollution and risk of dementia: results of the prospective three-city study (Publications)
68) for VaD per 5 microg/m(3) PM2.5 increase. No association was detected between NO2 or BC exposure and dementia risk. CONCLUSION: In this large cohort of older adults, long-term PM2.5 exposure was associated [...] 155 vascular/mixed dementia (VaD)). The 10-year moving average of PM2.5 concentrations ranged from 14.6 to 31.3 microg/m(3). PM2.5 concentration was positively associated with dementia risk: HR = 1.20 [...] l examination and confirmed by an independent committee of clinicians....
Monthly average air pollution models using geographically weighted regression in Europe from 2000 to 2019 (Publications)

The 5-fold CV showed generally good performance of the monthly GWR models across months and years (5-fold CV R(2): 0.31-0.66 for NO(2), 0.4-0.79 for [...] models to estimate monthly concentrations of regulated air pollutants (NO(2), O(3), PM(10) and PM(2.5)) between 2000 and 2019. Monthly average concentrations were collected from routine monitoring stations [...] estimate spatially-varying regression coefficients for each month. Model...

Past 5 year migration was found to be associated [...] temporal patterns of migration among past 5-year migrants with leprosy and a control group, and (3) examine social determinants of health associated with leprosy among past 5-year migrants. The study implemented [...] contact in the family, household and other leprosy contact,...
