    "abstract": "We study the propagation of non-strange and strange meson modes in hadronic\nmatter considering both isospin and strangeness mixings induced by quantum\nfluctuations in the medium. Baryons are described using the Quark Meson\nCoupling model extended to include interactions of strange quarks. In\nparticular we evaluate the dependence of the meson masses on the baryonic\ndensity, the strangeness fraction and the isospin asymmetry of the medium. We\nhave found a considerable admixture of strangeness and isospin in the\nsigma-mode in the high density regime.",
