    "abstract": "We study the modification of the nucleon nucleon interaction in a nuclear\nmedium in the scalar isoscalar channel, mediated by the exchange of two\ncorrelated ($\\sigma$ channel) or uncorrelated pions. For this purpose we use a\nstandard approach for the renormalization of pions in nuclei. The corrections\nobtained for the $NN$ interaction in the medium in this channel are of the\norder of 20% of the free one in average, and the consideration of short range\ncorrelations plays an important role in providing these moderate changes. Yet,\nthe corrections are sizable enough to suggest further studies of the stability\nand properties of nuclear matter.",
