INTRODUCTION This in vitro study compared the cytotoxic effects of three commercially available MTA formulations naming ProRoot MTA (PMTA), Angelus MTA (AMTA), and Root MTA (RMTA), with calcium-enriched mixture (CEM) cement and a new nanohybrid MTA (NMTA) on human dental pulp stem cells (DPSC). METHODS AND MATERIALS Four disc-shaped specimens of each(More)
The hydrolysis of 108 esters of norethisterone (17 alpha-ethynyl-17 beta-hydroxyestr-4-en-3-one) was studied in vitro using a rabbit liver preparation. Introduction of a double or triple bond into a straight-chain ester did not inhibit hydrolysis but a marked reduction in hydrolysis was produced on replacement of a methylene group by an oxygen atom.(More)
Four 17 beta-esters of norethisterone (17 alpha-ethynyl-17 beta-hydroxyestr-4-en-3-one), formulated both as oily solutions and aqueous suspensions, were administered intramuscularly to rabbits and free plasma levels measured for periods up to 9 weeks. For all formulations of the compounds, the disappearance of norethisterone following peak plasma levels(More)
