The seasonal nutrient mass balance of the dominant seagrass of the Mediterranean, Posidonia oceanica (L.) Delde, was evaluated in NE Spain in order to test the hypothesis that the effect of seasonal nutrient imbalance can be reduced by the reutllization of internal nutrient pools. To this end we investigated the seasonal and age-dependent variability of nitrogen and phosphorus concentration of ...

The effects of the initial emulsion structure (droplet size and emulsifier) on the properties of β-carotene-loaded emulsions and the bioavailability of β-carotene after passing through simulated gastrointestinal tract (GIT) digestion were investigated. Exposure to GIT significantly changed the droplet size, surface charge and composition of all emulsions, and these changes were dependent on the...

The importance of the trace metals zinc, copper and iron with respect to fetal growth in human pregnancy, with particular emphasis on their transfer to and uptake by the fetus, was discussed at a meeting of the Nutrition Society by Widdowson et al. (1974). The present paper examines the new information which is available in respect to the trace elements Zn, Cu, manganese, selenium and chromium....
