1Influence of dissolved organic matter character on mercury incorporation by planktonic organisms: An experimental study using oligotrophic water from Patagonian lakes显示文摘Ligands present in dissolved organic matter(DOM) form complexes with inorganic divalent mercury(Hg2+) afecting its bioavailability in pelagic food webs. This investigation addresses the influence of a natural gradient of DOM present in Patagonian lakes on the bioaccumulation of Hg2+(the prevailing mercury species in the water column of these lakes) by the algae Cryptomonas erosa and the zooplankters Brachionus calyciflorus and Boeckella antiqua. Hg2+accumulation was studied through laboratory experiments using natural water of four oligotrophic Patagonian lakes amended with197Hg2+. The bioavailability of Hg2+was afected by the concentration and character of DOM. The entrance of Hg2+into pelagic food webs occurs mostly through passive and active accumulation. The incorporation of Hg2+by Cryptomonas, up to 27% of the Hg2+amended, was found to be rapid and dominated by passive adsorption,and was greatest when low molecular weight compounds with protein-like or small phenolic signatures prevailed in the DOM.Conversely, high molecular weight compounds with a humic or fulvic signature kept Hg2+in the dissolved phase, resulting in the lowest Hg2+accumulation in this algae. In Brachionus and Boeckella the direct incorporation of Hg from the aqueous phase was up to3% of the Hg2+amended. The dietary incorporation of Hg2+by Boeckella exceeded the direct absorption of this metal in natural water,and was remarkably similar to the Hg2+adsorbed in their prey. Overall, DOM concentration and character afected the adsorption of Hg2+by algae through competitive binding, while the incorporation of Hg2+into the zooplankton was dominated by trophic or dietary transfer.María C.Diéguez Claudia P.Queimalios Sergio Ribeiro Guevara Mark Marvin-DiPasquale Carolina Soto Crdenas María A.Arribre 2013Journal of Environmental Sciences2013,25,10:6

9早餐的省略和在墨西哥的胃的癌症的风险显示文摘 <Abstract>AIM: To investigate factors associated with gastric cancer (GC) in the Mexican population using a validated questionnaire. METHODS: We designed and validated in Spanish a Questionnaire to Find Factors Associated with Diseases of the Digestive Tract using GC as a model. A crosssectional study using 49 subjects, with confirmed histopathological GC diagnosis, and 162 individuals without GC participated. Odds ratio and 95% CIs were estimated in univariate and multivariate analysis adjusted for possible confounding factors. In order to match agegroups, a multivariate sub-analysis was performed in subjects ≥ 39 years of age and in females and males separately. RESULTS: In the univariate analysis, we found an association between GC and education to primary level or below, low socioeconomic status, the use of dental prostheses, omission of breakfast, consumption of very hot food and drink, addition of salt to prepared foods, consumption of salt-preserved foods and the pattern of alcohol consumption. We found protection against GC associated with the use of mouthwash, food refrigeration and regular consumption of fruit and vegetables. In the multivariate sub-analysis with subjects of ≥ 39 years, the omission of breakfast was identified as a risk factor for GC. CONCLUSION: Our study suggests an association between the omission of breakfast and the failure to refrigerate food with GC in the Mexican population.Monserrat Verdalet-Olmedo Clara Luz Sampieri Jaime Morales-Romero Hilda Montero-L de Guevara lvaro Manuel Machorro-Castao Kenneth León-Córdoba 2012World Journal of Gastrointestinal Oncology2012,4,11:2
