Cyclomaltodextrinase (CDase, EC, maltogenic amylase (EC 3. 2.1.133), and neopullulanase (EC are reported to be capable of hydrolyzing all or two of the following three types of substrates: cyclomaltodextrins (CDs); pullulan; and starch. These enzymes hydrolyze CDs and starch to maltose and pullulan to panose by cleavage of alpha-1,4(More)
We measure the mass of the top quark using top-quark pair candidate events in the lepton+jets channel from data corresponding to 1 fb;{-1} of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron collider. We use a likelihood technique that reduces the jet energy scale uncertainty by combining an in situ jet energy calibration with(More)
The D0 Collaboration presents first evidence for the production of single top quarks at the Fermilab Tevatron pp[over ] collider. Using a 0.9 fb(-1) dataset, we apply a multivariate analysis to separate signal from background and measure sigma(pp[over ]-->tb+X,tqb+X)=4.9+/-1.4 pb. The probability to measure a cross section at this value or higher in the(More)
Porcine proliferative enteropathy(PPE) is an enteric disease been caused by Lawsonia intracellularis. It has become one of the critical problems in the pig industry. To investigate the prevalence of PPE in Korea, serum samples of 828 pigs from 65 herds were tested using indirect immunofluorescence antibody technique(IFA). The infection rate in individual(More)
This study was designed to determine whether the relaxant effect of apigenin was endothelium dependent and to examine the possible antiproliferative effect of apigenin. Apigenin relaxed the phenylephrine-precontracted endothelium-intact aortic rings with IC(50) value of 3.7+/-0.5 microM and removal of a functional endothelium significantly attenuated this(More)
PURPOSE The purpose of this work was to define the imaging spectrum of Castleman disease of the abdomen and to correlate the results with clinicopathologic findings. METHOD Seventeen patients (male/female 7:10; mean age 35.6 years) with pathologically proved Castleman disease in the abdomen were included in this study. Radiologic findings (CT, n =17; US,(More)
We report observation of the electroweak production of single top quarks in pp[over ] collisions at sqrt[s]=1.96 TeV based on 2.3 fb(-1) of data collected by the D0 detector at the Fermilab Tevatron Collider. Using events containing an isolated electron or muon and missing transverse energy, together with jets originating from the fragmentation of b quarks,(More)
OBJECTIVES We investigated whether systemic lupus erythematosus (SLE) patients could be distinguished based on the time of disease onset and, if so, whether the groups differed in their clinical and laboratory features in ethnically homogeneous Korean patients. METHODS We enrolled 201 SLE patients with available clinical data at the time of onset of SLE(More)
Iridoviruses infect a wide variety of wild and cultured fish. Those iridoviruses belonging to the genus Ranavirus, in the Iridoviridae family, cause systemic disease in infected animals with a high morbidity and mortality. This paper reports the cloning, sequencing, and expression of the rock bream iridovirus (RBIV) major capsid protein (MCP) in an(More)
Cyclodextrin glycosyltransferase (CGTase; EC catalyzes the degradation of starch into cyclodextrins through an intramolecular transglycosylation reaction. Tyr-89, Asn-94, and Tyr-100 are located near the putative active center. To analyze their roles in product specificity, Tyr-89, Asn-94, and Tyr-100 of CGTase from alkalophilic Bacillus sp. I-5(More)
