The genome of Streptococcus sanguinis is a circular DNA molecule consisting of 2,388,435 bp and is 177 to 590 kb larger than the other 21 streptococcal genomes that have been sequenced. The G+C content of the S. sanguinis genome is 43.4%, which is considerably higher than the G+C contents of other streptococci. The genome encodes 2,274 predicted proteins,(More)
Flunisolide (6 alpha-fluoro-11 beta,16 alpha,17 alpha,21-tetrahydroxypregna-1,4-diene-3,20-dione 16,17-acetonide) is a potent corticoid used clinically in topical formulations. Three men were given single 2-mg intravenous and oral doses of 14C-labeled flunisolide and plasma and urine concentrations of flunisolide and a major metabolite, 6 beta,11 beta,16(More)
In earlier safety studies, naproxen, 600 mg three times daily, was administered to healthy subject without significant adverse effects. Another study demonstrated that single doses of 500 to 900 mg resulted in accelerated renal clearance and a nonlinear naproxen plasma level response after the higher doses. Our report describes the pharmacokinetics of(More)
It has been shown that the analgesic and cyclooxygenase inhibitor activity of ketorolac tromethamine (KT), which is marketed as the racemic mixture of (-)S and (+)R enantiomers, resides primarily with (-)S ketorolac and that the ulcerogenic activity of this agent also resides in (-)S ketorolac. Resolution of individual enantiomers for analysis in plasma(More)
The pharmacokinetics of ganciclovir was evaluated in 21 patients with life- or sight-threatening cytomegalovirus infections. Thirteen patients had normal renal function and eight patients had various degrees of renal insufficiency. Most patients received 5 mg of ganciclovir/kg as a 1-hour intravenous infusion twice daily for periods of up to 2 weeks.(More)
