Incubation of estrone (1a) with Streptomyces roseochromogenes ATCC 13400 yielded a mixture of 3,16 alpha-dihydroxyestra-1,3,5(10)-trien-17-one (3a) and 3,17 beta-dihydroxyestra-1,3,5(10)-trien-16-one (4a). Transformation of 3-methoxyestra-1,3,5(10)-trien-17-one (1b), 3-hydroxyestra-1,3,5(10),9(11)-tetraen-17-one (2a), and(More)
An improvement o f an existing Pitch Detection Algorithm is presented in this paper. The solution reduces the computational load of its precedent algorithm and introduces a voiced/unvoiced decision step to reduce the number of errors. The eciency of this improved system is tested with a semi-automatically segmented speech data base according to the(More)
The synthesis and preliminary assays as hypocholesterolemic agents of five N-diphenylmethylpiperazines are described. The evaluations were carried out in hypercholesterolemic mice and two of these compounds were more effective than bezafibrate in the test employed. The di-p-chlorosubstituted compounds showed higher activity than their corresponding(More)
