Does amantadine , a N-methyl-D-aspartate receptor antagonist , enhance postoperative analgesia in women undergoing abdominal hysterectomy?
Because of no differences in postoperative pain or opioid consumption, we conclude that a preoperative dose of 200 mg amantadine IV fails to enhance postoperative analgesia in patients undergoing elective abdominal hysterectomy.
Activation of KIT by a gain-of-function somatic mutation is a novel mechanism of resistance to crizotinib in ROS1-rearranged NSCLC. This bypass signaling pathway serves as a ROS1-independent mechanism of resistance, similarly to previously identified epidermal growth factor receptor or Kirsten rat sarcoma viral oncogene homolog/neuroblastoma RAS viral oncogene homolog signaling pathways, and can potentially be targeted by KIT inhibitors.
