Do european multi-centre study of the Nucleus Hybrid L24 cochlear implant?
Useful residual hearing was conserved in 88% of subjects. Speech perception was significantly improved over preoperative hearing aids, as was sound quality and quality of life.
Laccases have a great potential of application in bioremediation processes. White rot fungi produces several laccase isoenzymes and many of them have been purified and characterized. However, the additive or synergic action between laccase isoenzymes in dye decolourization has not yet been described. Such studies will help to better understand their action and to improve the process with isoenzymes mixtures. This study showed synergistic action between isoenzymes laccases produced by Trametes hirsuta Bm2 during decolourization of indigo carmine.
