BACKGROUND Epitopes are the sites to which antibodies bind. Both alpha and beta peptide chains of the human leukocyte antigen-DQ heterodimers (DQA1 and DQB1, respectively) contain polymorphic regions. We can identify DQA1 and DQB1 epitopes by DQ single antigen beads assay of the antibodies, correlating the beads' reaction patterns with either DQA1 or DQB1 alleles. METHODS Sera from 74 transpl...

Data Stream Management Systems (DSMS) have been proposed to address the challenges of applications which produce continuous, rapid streams of data that have to be processed in real-time. Data quality (DQ) plays an important role in DSMS as there is usually a trade-off between accuracy and consistency on the one hand, and timeliness and completeness on the other hand. Previous work on data quali...

Research Article Rosanne Price Monash University [email protected] Graeme Shanks The University of Melbourne [email protected] It has been proposed that metadata describing data quality (DQ), termed DQ tags, be made available in situations where decision makers are unfamiliar with the data context, for example, in data warehouses. However, there have been conflicting reports as to t...

The objective of this study was to examine the impact of chronic hyperoxic exposure (95% O2 for 48 h) on intact bovine pulmonary arterial endothelial cell redox metabolism of 2,3,5,6-tetramethyl-1,4-benzoquinone (duroquinone, DQ). DQ or durohydroquinone (DQH2) was added to normoxic or hyperoxia-exposed cells in air-saturated medium, and the medium DQ concentrations were measured over 30 min. DQ...

DQ-DHT is a resource discovery algorithm that combines the Dynamic Querying (DQ) technique used in unstructured peer-to-peer networks with an algorithm for efficient broadcast over a Distributed Hash Table (DHT). Similarly to DQ, DQ-DHT dynamically controls the query propagation on the basis of the desired number of results and the popularity of the resource to be located. Differently from DQ, ...

Epstein-Barr virus (EBV) infects B cells and ~95% of adults are infected. EBV glycoprotein gp42 is essential for entry of virus into B cells. EBV gp42 binds to the β1 chain of HLA-DQ, -DR, and -DP on B cells, and uses these molecules for infection. To investigate if certain HLA-DQ alleles are associated with EBV seronegativity, we recruited ~3,300 healthy adult blood donors, identified 106 EBV-...

In this work, we have studied the pH-dependence of the formation of DQCB[8] complexes by surface-enhanced Raman scattering (SERS) spectroscopy. The SERS spectra suggest that at acidic pH CB[8] can form a binary complex with the dication DQ(+2) while at higher pH ternary complexes with the radical cation dimer (DQ(+)˙)(2) and the radical cation-dication dimer (DQ(+)˙DQ(+2)) are formed. The pH-en...

Distributed Hash Tables (DHTs) provide scalable mechanisms for implementing resource discovery services in structured Peer-to-Peer (P2P) networks. However, DHT-based lookups do not support some types of queries which are fundamental in several classes of applications. A way to support arbitrary queries in structured P2P networks is implementing unstructured search techniques on top of DHT-based...

SAITO, K. Effects of Diquat on Cell Growth; and Macromolecule Synthesis in Cultured Pneumocytes. Tohoku J. exp. Med., 1986, 148 (1), 35-39 The effects of diquat (DQ) on cell growth and macromolecule synthesis were investigated in cultured rat, feline and human. pneumocytes. DQ at 10-3 M and 10-5 M showed timeand dose-dependent inhibition of cell growth for 7 days. The incorporation of 3H-thymid...

A new HLA-DQ-related genetic system with two alleles, 2B3 and TA10, defined serologically by MAbs and alloantisera, showed an almost perfect correlation with charge differences on DQ beta molecules, as well as with two polymorphic DNA fragments hybridizing with a DQ beta probe and various restriction enzymes on a panel of 14 DR4+ homozygous typing cells. It was therefore concluded that the sero...
