Protocol: Male Wistar rats: control-sedentary; rhEPO-50 IU/Kg/3xwk; swimming (EX)-1 hr, 3x/wk; EX+ EPO. Hematology, catecholamines and serotonin, redox status and inflammation, were assessed. One rat of EX+ EPO group suffered a sudden death episode. Results: rhEPO treatment in trained rats promoted several markers of increased CV risk. The sudden ...

Representative tissue samples of each species were analysed by using atomic absorption spectroscopy with flame. Validation of methodology was carried out using a certified reference material (TORT-1). The ranges of concentrations found for Cd, Cr and Pb in the 3 species were, respectively, 0.21-4.32, 0.38-12.62 and 0.43-31.10 mg kg À1 dry weight. In relation to the results obtained and the average of each individual metal in the different species of bivalves, Pb concentrations were found in higher levels rather than those of other metals reported by other authors in a similar work, this element constitutes a potential health hazard for the consumers of shellfish. The results were statistically evaluated for possible correlations in the content of metals in different species and in different sites of origin.

The program consists of two scripts, the first dedicated to the elaboration of the calibration curve. The emission of fluorescent light, detected by image analysis, is correlated with the concentration of CBD solutions. This calibration is then used (second script) to determine the concentration of CBDs adsorbed on cellulosic fibers. This method allows the direct estimation of the surface concentration of adsorbed CBDs, which usually is not accurately calculated from depletion studies, since the surface area is hardly known. By observing different spots in the surface of the fibers, site-specific information is obtained. It was verified that the physically heterogeneous fibers exhibit different amounts of adsorbed CBDs.
