Does ketamine elicit sustained antidepressant-like activity via a serotonin-dependent mechanism?
These observations are consistent with a role for 5-HT in mediating sustained antidepressant activity of ketamine in the FST. Molecular and cellular changes induced by ketamine may produce a rapid adaptation of 5-HT transmission which underlies the antidepressant response.
Considerable discrepancies exist between preoperative neck diameter and infrarenal aortic length measurements obtained from CT scans and angiograms used to evaluate candidates for endovascular aortic aneurysm repair. CT alone may not be adequate for predicting the feasibility of endovascular AAA repair.
