Résumé : National audience
Due to their extended indications, intravenous immunoglobulins (IVIg) are increasingly used in hospital setting. After injection, classical IVIg half-life reaches more than 3weeks. IVIg result from the pooling of many blood donations and contain all natural antibodies usually found in the general population. Administered antibodies are known to interfere with many diagnostic assays, particularly those used for infectious serology. It is not recommended to perform serological determination after IVIg infusion. It is recommended to keep a delay of at least 4months after IVIg infusion before doing any serological assay; failure to do so will result in misinterpretation of biological findings. Interpretation of any serological test after IVIg administration should be particularly cautious.

Résumé : International audience
Turbinaria turbinata brown seaweeds were tested as carbon electrode material in symmetric, electrochemical supercapacitors. The electrochemical properties of the carbon materials were characterised for their application as supercapacitors using cyclic voltammetry, galvanostatic charge/discharge method and electrochemical impedance spectroscopic analyses. Our initial results showed that the optimal behaviour was obtained for the sample prepared by pyrolysis at 800 degrees C. The average surface area of the carbon was 812 m(2)/g. Electrochemical tests with an organic electrolyte gave the following interesting results: a capacitance of 74.5 F/g, a specific series resistance of 0.5 Omega cm(2) and an ionic resistivity of 1.3 Omega cm(2). These results show the promising capacitive properties of carbon derived from seaweeds and their application in electrochemical supercapacitors. (C) 2013 Academie des sciences.
