Background Despite the success of HMG-CoA reductase inhibitor (statin) therapy in reducing atherosclerotic cardiovascular events, a residual risk for cardiovascular events in patients with coronary artery disease (CAD) remains. Long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are promising anti-atherosclerosis agents...
This study aimed to elucidate the predictors of improvements in exercise capacity during cardiac rehabilitation (CR) in the recovery phase after coronary artery bypass graft surgery (CABG) versus acute myocardial infarction (AMI). We studied 152 patients (91 after AMI and 61 after CABG) who participated in a 3-month CR program. All patients underwent a cardiopulmonary exercise test, blood tests, maximal...
The difference between two strings is the minimum number of editing steps (insertions, deletions, changes) that convert one string into the other. Let S be a finite set of strings, let T be a subset of S, and let δ be a positive integer. A δ-characteristic string of T under S is a string that is a common substring of T and that has at least δ-differences from any substring of any string in S − T....
An object-oriented database system is being developed, which is used to store protein three-dimensional structure data. Proteins from Brookhaven's Protein Data Bank (PDB) axe classified by their enzyme code numbers and each protein is represented as a composite object. The system provides a number of methods to avoid writing lengthy Object-SQL (OSQL) statements for complex queries. Furthermore, fixed...
Let S be a finite set of strings and let T be a subset of S. A characteristic string of T under S is a string that is a common substring of T and that is not a substring of any string in S-T. We present a lineartime algorithm for deciding whether or not there exists a characteristic string of T under S. If such a string exists, then the algorithm returns all the shortest characteristic strings of...
In relational databases, operations including joins sometimes become a cause of performance problems. We study scheme transformations to reduce the number of joins used by a class of routine database activities whose access patterns are fixed. Two scheme operations, merge and copy, are defined to transform relation schemes. The former merges two relation schemes into one, and the latter copies a functional...
