| the striking geographical pattern of gastric cancer mortality in spain: environmental hypotheses revisited. | gastric cancer is decreasing in most countries. while socioeconomic development is the main factor to which this decline has been attributed, enormous differences among countries and within regions are still observed, with the main contributing factors remaining elusive. this study describes the geographic distribution of gastric cancer mortality at a municipal level in spain, from 1994-2003. | 2009 | 19737377 |
| determinants of organochlorine levels detectable in the amniotic fluid of women from tenerife island (canary islands, spain). | organochlorines (ocs) tend to accumulate in human tissues and can be measured in amniotic fluid (af). the detection of ocs in af samples reflects intrauterine exposure of human beings to these persistent organic pollutants. the present study was performed to evaluate the level of contamination of af by ocs in 100 pregnant women from tenerife island (canary islands, spain). gas chromatography/mass spectrometry (gc/ms) was used to identify and quantify the analytes, including 7 polychlorobiphenyl ... | 2009 | 19403124 |
| consort hypersensitivity pneumonitis. | to date, there is little information in the literature that hypersensitivity pneumonitis due to birds may occur without direct contact to birds. a 62-yr-old pensioner developed mild flu-like symptoms, fatigue and polyuria several hours after each meeting with his new female partner, either in hotels or his apartment. after divorcing from her ex-husband, who was a canary fancier, the female had moved into a bungalow approximately 6 months earlier. when the couple met for the first time at the bun ... | 2009 | 19407057 |
| prenatal environmental effects match offspring begging to parental provisioning. | the solicitation behaviours performed by dependent young are under selection from the environment created by their parents, as well as wider ecological conditions. here we show how mechanisms acting before hatching enable canary offspring to adapt their begging behaviour to a variable post-hatching world. cross-fostering experiments revealed that canary nestling begging intensity is positively correlated with the provisioning level of their own parents (to foster chicks). when we experimentally ... | 2009 | 19419982 |
