Videographic analysis of flight behaviours of host-seeking <em>Anopheles arabiensis</em> towards BG-Malaria trap (Publications)
attractants all influence mosquito activity in vicinity of the traps which can be readily visualized using infrared cameras to accelerate trap development and testing. The greater activity of host-seeking [...] an adaptation of the well-known BG-Sentinel trap (BGS) with greater trapping efficiencies for anopheline and culicine mosquitoes. Its continued optimization requires greater understanding of mosquito flight [...] ution infrared cameras (68 frames/second) to track flight behaviors of...

Air pollution and incidence of cancers of the stomach and the upper aerodigestive tract in the European Study of Cohorts for Air Pollution Effects... (Publications)
During average follow-up of 14.1 years of 305 551 individuals, 744 incident cases of gastric cancer and 933 of UADT cancer occurred. The hazard ratio for an increase of 5 microg/m(3) of PM2.5 was 1.38 (95%-CI [...] the relevance for cancers of the stomach and upper aerodigestive tract (UADT). We investigated the association of long-term exposure to ambient air pollution with incidence of gastric and UADT cancer in [...] associations were found for any of the other exposures considered....

analyses of one of the two samples using "bead-beating" for DNA extraction. At follow-up, 80 samples were negative according to both PCR and KK and 173 were positive with both methods for any of the STHs [...] BACKGROUND: Diagnosis of soil-transmitted helminths (STHs) in developing countries is commonly based on microscopic detection of eggs in stool samples, using the Kato-Katz (KK) method, which has a poor [...] sensitivity for detecting light intensity infections. We compared the performance ...

Reactivity to accelerometer measurement of children and adolescents (Publications)
PURPOSE: Awareness of being monitored can influence participants' habitual physical activity (PA) behavior. This reactivity effect may threaten the validity of PA assessment. Reports on reactivity when [...] measurement day, and whether the day of the week and the day on which measurement started influence these differences. METHODS: Accelerometer data (Counts per minute, cpm) of children and adolescents (n = 2081) [...] pooled from eight studies in Switzerland with at least 10 hours of daily...
