Abstract
In this talk I present recent developments in chiral dynamics of hadrons and hadrons in a medium addressing the following points: interaction of the octet of pseudoscalar mesons with the octet of baryons of the nucleon, showing recent experimental evidence on the existence of two $Î(1405)$ states, the interaction of the octet of pseudoscalar mesons with the decuplet of baryons of the $Î$, with particular emphasis on the $Î(1520)$ resonance, dynamically generated by this interaction. Then I review the interaction of kaons in a nuclear medium and briefly discuss the situation around the claims of deeply bound states in nuclei. The large renormalization of the $Î(1520)$ in the nuclear medium is shown as another example of successful application of the chiral unitary techniques.
