The effects of the duration of the light phase photoperiod (8 h light or 16 h light) on the growth and hepatic insulin-like growth factor-I (IGF-I) gene expression in Nile tilapia Oreochromis niloticus were evaluated. There was a slight but not significant tendency for fish in the long light phase group (L(P)) to display elevated specific growth rate (G)(More)
The extraction of proteins from PLGA/PLA microspheres by a two-immiscible liquid phases system with the addition of surfactants was investigated. First, the extraction without surfactants and the interaction between proteins (IFN-α2b and EGF) and empty microspheres (PLGA or PLA) was studied. Next, proteins stability in presence of different surfactants was(More)
