Effects of DQ-2511, a new peripherally acting anti-ulcer agent, on vagally induced gastric acid output and mucosal blood flow (MBF) were investigated in urethane-anesthetized rats with gastric fistula. Intravenous infusion of DQ-2511 (2 or 20 mg/kg/hr, for 30 min) reduced the vagally induced gastric acid output and MBF, and these inhibitory effects were abolished by pretreatment with phentolami...

Let Uq(sl2) be the quantized enveloping algebra associated to the simple Lie algebra sl2. In this paper, we study the quantum double Dq of the Borel subalgebra Uq((sl2) ) of Uq(sl2). We construct an analogue of Kostant–Lusztig Z[v, v]-form for Dq and show that it is a Hopf subalgebra. We prove that, over an algebraically closed field, every simple Dq-module is the pullback of a simple Uq(sl2)-m...

Nowadays, organizations may have Web portals tailoring several websites where a wide variety of information is integrated. These portals are typically composed of a set of Web applications and services that interchange data among them. In this setting, there is no way to find out how the quality of the interchanged data is going to evolve successively. A framework is proposed for establishing t...

OBJECTIVES We examine the following: (1) the appropriateness of using a data quality (DQ) framework developed for relational databases as a data-cleaning tool for a data set extracted from two EPIC databases, and (2) the differences in statistical parameter estimates on a data set cleaned with the DQ framework and data set not cleaned with the DQ framework. BACKGROUND The use of data containe...

NAD(P)H:quinone oxidoreductase 1 (NQO1) plays a dominant role in the reduction of the quinone compound 2,3,5,6-tetramethyl-1,4-benzoquinone (duroquinone, DQ) to durohydroquinone (DQH2) on passage through the rat lung. Exposure of adult rats to 85% O2 for > or =7 days stimulates adaptation to the otherwise lethal effects of >95% O2. The objective of this study was to examine whether exposure of ...

A subunit vaccine for Plasmodium falciparum malaria will need to contain well-defined T helper cell epitopes that induce protective immune responses to the parasite. One major barrier to the use of subunit vaccines is the requirement for T helper cell epitopes to be presented by the HLA class II molecules that are present in the population being vaccinated. Since the majority of malaria studies...
