6-Methylbenz|a (anthracene (6-MBA) is metabolized by rat liver microsomes to form 3-hydroxy-6-MBA, 4-hydroxy-6-MBA, 5hydroxy-6-MBA, 6-MBA frans-3,4-, 5,6-, 8,9-, and 10,11-dihydrodiols, and 4-hydroxy-6-MBA frans-10,11-dihydrodiol as the identifiable metabolites. 6-Hydroxymethylbenz[a]anthracene and its phenolic and dihydrodiol metabolites are also formed. The unique metabolites identified in 6-...

A novel Schiff base derivative of 4-aminoantipyrine, that is, (E)-4-(2-methoxybenzylideneamino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one (MBA-dMPP), was synthesized and characterized by FT-IR, 1H-NMR, and EI-MS. Single-crystal X-ray diffraction data revealed MBA-dMPP adopts a trans configuration around its central C=N double bond, and forms orthorhombic crystals. XRD revealed that MBA-dMPP po...

Ureaplasma urealyticum has been divided into 14 serovars. Recently, subdivision of U. urealyticum into two species has been proposed: U. parvum (previously U. urealyticum parvo biovar), comprising four serovars (1, 3, 6, 14) and U. urealyticum (previously U. urealyticum T-960 biovar), 10 serovars (2, 4, 5, 7-13). The multiple-banded antigen (MBA) genes of these species contain both species and ...

This paper is unique in its comparison of full programs, rather than a comparison of courses, as previously documented in Web-based education literature. Two similar MBA programs utilizing two different delivery formats (i.e., online MBA and on-campus MBA) were studied. The Learning Skills Profile (LSP) was used to assess the managerial skills when entering and graduating the programs. A compar...

In this work, we investigate the mode of chiral interactions between the asymmetric Co(II) salen complex, (S,S)-N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexane-diamine-Co(II) ([Co(1)]), and single enantiomers of methylbenzylamine (MBA) using different continuous-wave and pulsed electron paramagnetic resonance techniques combined with density functional theory computations. While [Co(1)]...

Background: The multiple banded antigen (MBA), a surface-exposed lipoprotein, is a proposed virulence factor of Ureaplasma spp. We previously demonstrated that the number of Ureaplasma parvum MBA size variants in amniotic fluid was inversely proportional to the severity of chorioamnionitis in experimentally infected pregnant sheep. However, the effect of ureaplasma MBA size variation on inflamm...

Conventional fold recognition techniques rely mainly on the analysis of the entire sequence of a protein. We present an MBA method to improve performance of any conventional sequence-based fold assignment. The method uses sequence motifs, such as those defined in the Prosite database, and the SwissProt annotation of the fold library. When combined with a simple SDP method, the coverage of MBA i...

Abstract Some N-substituted allylarylamines, for example, N-(1-methyl-2-butenyl) aniline (N-MBA) form, upon isomerization, not only ortho- , but also para- and 2,6-disubstituted derivatives, which does fit into generally accepted theory. The amino-Claisen rearrangement (ACR) of N-MBA is catalyzed by Lewis acids, cationites, arylamine hydrochlorides. This work presents the results studies ACR in...
