    "abstract": "In these lectures I make an introduction to chiral unitary theory applied to\nthe meson baryon interaction and show how several well known resonances are\ndynamically generated, and others are predicted. Two very recent experiments\nare analyzed, one of them showing the existence of two\n  $\\Lambda(1405)$ states and the other one providing support for the\n  $\\Lambda(1520)$ resonance as a quasibound state of $\\Sigma(1385) \\pi$. The\nuse of chiral Lagrangians to account for the hadronic interaction at the\nelementary level introduces a new approach to deal with the modification of\nmeson and baryon properties in a nuclear medium. Examples of it for $\\bar{K}$,\n$\\eta$ and $\\phi$ modification in the nuclear medium are presented.",
