INTRODUCTION The purpose of this study was to compare healing after root-end surgery by using grey mineral trioxide aggregate (MTA) and EndoSequence Root Repair Material (RRM) as root-end filling material in an animal model. METHODS Apical periodontitis was induced in 55 mandibular premolars of 4 healthy beagle dogs. After 6 weeks, root-end surgeries were(More)
INTRODUCTION The purpose of this study was to investigate odontogenic and osteogenic cell adhesion, proliferation, and survival on the surface of a newly developed bioceramic material (EndoSequence Root Repair Material [RRM]; Brasseler USA, Savannah, GA) and compare it with mineral trioxide aggregate (gray MTA) (ProRoot MTA; Dentsply Tulsa Dental, Tulsa,(More)
Bladder carcinoma is the fourth most common cancer in men, however cardiac metastases from the bladder are exceedingly rare. There have been 5 documented cases of transitional cell carcinoma causing cardiac tamponade. There have been 3 documented cases of urothelial carcinoma presenting as cardiac tamponade with positive cytology.1e3 We will discuss a case(More)
Reduction of the quinoline ring in an alpha(v)beta(3) antagonist yielded a 1,2,3,4-tetrahydro derivative as two diastereomers, the four isomers of which were separated by sequential chiral HPLC. Two isomers had significant alpha(V)beta(3) antagonist activity with improved oral bioavailability, relative to the corresponding quinoline derivative.
