Última An Integrated Biomarker Approach Using Flounder to Improve Chemical Risk Assessments in the Heavily Polluted Seine Estuary ArchiMer Borcier, Elodie; Charrier, Gregory; Couteau, Jérôme; Maillet, Géraldine; Le Grand, Fabienne; Bideau, Antoine; Waeles, Mathieu; Le Floch, Stephane; Amara, Rachid; Pichereau, Vianney; Laroche, Jean. The objective of this study was to develop an integrative approach in ecotoxicology (from biomarkers to population genetics) to assess the ecological status of fish populations. Flounders (Platichthys flesus) collected after the spawning season in the heavily polluted Seine estuary were compared with the moderately polluted Bay of Douarnenez. The muscle energetic reserves were highly depleted in Seine vs. Douarnenez fish. The Seine fish displaying a reduced capacity to manage the oxidative stress and a higher energetic metabolism. An increase in the content of muscle membrane phospholipids (sphingomyelin, phosphatidylserine, free sterols) was detected in the Seine vs. Douarnenez fish. The data integration allowed to hypothesize relationships between... Tipo: Text Palavras-chave: Platichthys flesus; Estuaries; Biomarkers; Bioenergetics; Polar lipids; Population genetics.

Pérola BABT Martins Júnior,Raimundo Rômulo; Oliveira,Micheline Soares Costa; Baccache,Maria Ary; Paula,Fernando Monteiro de. Bean leaves (Phaseolus vulgaris L.) cv. Pérola were used to evaluate the water deficit effects in polar lipids composition and in the electric conductivity. The results showed that the water deficiency a effected in the electrolytes loss which increased gradually in response to water deficit. This suggested a compartimentalization loss, due to the structural cellular membranes elements degradation. Total lipids contents decreased by reason of the water stress action. The polyunsaturated fatty acid contents (linoleic and linolenic acids) suffered a decrease while saturated fatty acid (palmitic and stearic acids) increased. The imbalance in the fatty saturated/unsaturated acid relation led to a reduction in the unsaturation index. The electrolytes loss...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132008000200016 Réponses physiologiques et biochimiques à une limitation nutritive en phosphore ou en azote sur la réorientation métabolique des lipides polaires chez différentes espèces de microalgues marines ArchiMer Huang, Bing. Betaine lipids (BL) are P-free polar lipids, conversely to phospholipids (PL). The metabolic reorientation induced by phosphorus (P) limitation in microalgae producing BL (Tisochrysis lutea and Diacronema lutheri, Haptophyta) or producing low levels of BL (Phaeodactylum tricornutum, Bacillariophyta) was compared to that induced by nitrogen (N) limitation. The carbon destiny and flow in different biosynthetic pathways were studied with a multidisciplinary approach. P or N limitation differently affected carbon metabolism according to microalgal species. P limitation highly decreased photosynthetic activity and respiration of P. tricornutum and T. lutea. Consequently, carbon accumulation was higher than under N limitation in these two species. Both...
