You will be given a definition of a task first, then some input of the task.
Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Although serum amyloid A (SAA) is an established biomarker of coronary artery disease (CAD), its direct role in matrix degradation is obscure. This study investigated the effect of SAA on the expression of matrix metalloproteinase-10 (MMP-10) in endothelial cells. The effect of celecoxib on SAA-dependent MMP-10 expression and its possible mediator were also investigated.', 'From our time course microarray screening, SAA (20 microg/ml) was found to increase MMP-10 mRNA expression over time (4-48 h) in human endothelial cells. Quantitative real-time PCR confirmed this transcriptional induction. Correspondingly, secreted MMP-10 protein was also markedly induced by SAA treatment for 24 h in a dose-dependent manner. We further examined cyclooxygenase-2 (COX-2) and its major product, prostaglandin E(2) (PGE(2)), as possible mediators of MMP-10 induction. Direct PGE(2) treatment could result in MMP-10 induction. Celecoxib, a selective COX-2 inhibitor, suppressed MMP-10 secretion induced by SAA.
