PURPOSE The results of recent published studies focusing on IL-8 polymorphism in colorectal cancer susceptibility have often been inconsistent. We therefore carried out a meta-analysis based on independent studies to assess the association. METHODS Nine case-control studies with 7,003 individuals (3,019 cases and 3,984 controls) were included in this meta-analysis through searching the databa...

The definition of data transformations between heterogeneous schemas is a critical activity of any database application. Currently, automated tools provide high level interfaces for the discovery of correspondences between elements of schemas, but transformations (i.e., schema mappings) need to be manually specified every time from scratch, even if the problem at hand is similar to one that has...

OBJECTIVES The main objective was to assess the credibility of the evidence using Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) in oral health systematic reviews on the Cochrane Database of Systematic Reviews (CDSR) and elsewhere. STUDY DESIGN AND SETTING Systematic Reviews or meta-analyses (January 2008-December 2013) from 14 high impact general dental and special...

Seismic databases and processing tools currently available are mainly limited to classic three-component seismic recordings and cannot handle collocated multi-component, multidisciplinary datasets easily. Further, these seismological databases depend on event-related data and are not able to manage state of the art continuous waveform data input as well. None of them allows for automated reques...

In the last fteen years, lock managers for regular disk-based database systems have seen little change. This is not without reason, since traditional memory-resident lock managers have always been much faster than disk-based database storage managers and disk-based database systems had few alternative design options. However, the introduction of memory-resident database systems has created both...

BACKGROUND Previous studies reported that Atorvastatin (ATOR) can improve the efficacy of Mesenchymal stem cells (MSCs) transplantation after acute myocardial infarction (AMI). However, the results of those studies were inconsistent. To clarify the beneficial effects of atorvastatin added to the cell therapy with MSCs in animal model of acute myocardial infarction (AMI), we performed a systemat...

We propose a new method for generating consistency-preserving transaction programs for (view) updates in deductive databases. The method augments the deductive database schema with a set of transition and internal events rules, which explicitly define the database dynamic behaviour in front of a database update. At transaction-design-time, a formal procedure can use these rules to automatically...

Model Driven Software Development (MDSD) has matured over the last few years and is now becoming an established technology. As a consequence, dealing with evolving meta-models and the necessary migration activities of instances of this meta-model is becoming increasingly important. Approaches from database schema migration tackle a similar problem, but cannot be adapted easily to MDSD. This pap...
