Neonatal hyperthyroidism alters submandibular gland epidermal growth factor response to thyroxine in the adult mouse.

abstract：:Although chronic cocaine use is cardiotoxic, its use remains problematic in athletics. Hence adaptive changes induced in the heart by superimposing chronic cocaine use on an exercise training are of interest but remain poorly understood. Therefore this study investigated the effects of cocaine treatment combined with ...
