Learning outcomes of the course unit
The purpose of the course is to gain knowledge of the etio-pathogenetic mechanisms of diseases in order to identify new therapeutic targets. Notions of semeiotic and medical terminology are important for the future profession.
Getting through Fisiologia generale and Biochimica/Biochimica applicata.
