Measuring dopaminergic function in the 6-OHDA-lesioned rat: a comparison of PET and microdialysis.

abstract：PURPOSE:Pathological complete response to the neoadjuvant therapy (NAT) for triple negative breast cancer (TNBC) is predictive of prolonged patient survival. Methods for early evaluation of NAT efficiency are still needed, in order to rapidly adjust the therapeutic strategy in case of initial non-response. One option f...
