dentin bonding agents (dba) have been used as root-end filling materials. present study evaluated the effects of polymerized dba on secretion of pro-inflammatory cytokines by normal human monocytes. in this study, monocytes were directly isolated from human peripheral blood, and exposed to cured scotch bond 1 (single bond) and prime and bond for 36 and 72 hours. secretion of il-1β and tnf-α in ...

Automating physical database design has remained a long-term interest in research due to substantial performance gains afforded by optimised structures. Despite significant progress, majority of today's commercial solutions are highly manual, requiring offline invocation administrators (DBAs). This status quo is untenable: identifying representative static workloads no longer realistic; and too...

The choice of database layout, i.e., how database objects such as tables and indexes are assigned to disk drives can significantly impact the I/O performance of the system. Today, DBAs typically rely on fully striping objects across all available disk drives as the basic mechanism for optimizing I/O performance. While full striping maximizes I/O parallelism, when query execution involves co-acc...

These data Indicate Lhat in this instance 1-NP and the DNPs did not contribute significantly to the induction of skin tumors in mice. Of the compounds detected. BoP was the major contributor to the tumorigenic potency in the Nissan extract (Table C.3). Benzo[b]fluoranthene (BbF) and benzo[;lfluoranthene (BjF) were also significant contributors. ln the case of the Volk!Magen extract. the relativ...

PURPOSE Insomnia is a substantive primary care issue that leads to adverse outcomes. These can be improved by addressing factors that accentuate insomnia severity. Accordingly, this study identifies correlates of insomnia severity and determines whether these relationships vary with sociodemographic attributes. METHODS This correlational cross-sectional study was conducted in a hospital-spons...

The growth in variety and volume of OLTP (Online Transaction Processing) applications poses a challenge to OLTP systems to meet performance and cost demands in the existing hardware landscape. These applications are highly interactive (latency sensitive) and require update consistency. They target commodity hardware for deployment and demand scalability in throughput with increasing clients and...

Long running decision support queries can be resource intensive and often lead to resource contention in data warehousing systems. Today, the only real option available to the DBAs is to carefully select one or more queries and terminate them. However, the work done by such terminated queries is entirely lost even if they were very close to completion and these queries will need to be run in th...

Depressive-like forms of waking inactivity have been recently observed in laboratory primates and horses. We tested the hypotheses that being awake but motionless within the home-cage is a depression-like symptom in mice, and that in impoverished housing, it represents an alternative response to stereotypic behaviour. We raised C57BL/6 ('C57') and DBA/2 ('DBA') females to adulthood in non-enric...

Modern DBMSes are designed to support many transactions running simultaneously. DBMS thrashing is indicated by the existence of a sharp drop in transaction throughput. The thrashing behavior in DBMSes is a serious concern to DBAs engaged in on-line transaction processing (OLTP) and on-line analytical processing (OLAP) systems, as well as to DBMS implementors developing technologies related to c...
