Identification and local delivery of vasodilators for the reduction of ureteral contractions.

Kidney stones and ureteral stents can cause ureteral colic and pain. By decreasing contractions in the ureter, clinically prescribed oral vasodilators may improve spontaneous stone passage rates and reduce the pain caused by ureteral stenting. We hypothesized that ureteral relaxation can be improved via the local administration of vasodilators and other smooth muscle relaxants.

Ovarian cancer spheroid shrinkage following continuous exposure to cisplatin is a function of spheroid diameter.

Objective: Most ovarian cancer patients present with advanced-stage disease, disseminated in the peritoneal cavity. Standard treatment involves surgical resection of all visible tumor, followed by delivery of systemic therapy. Patients with advanced-stage disease may be candidates for intraperitoneal (IP) chemotherapy following surgical debulking.
