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.

Example Input: Infarct heterogeneity has been shown to be independently associated with adverse outcomes in previous smaller studies. However, it is unknown whether infarct characterization is an independent predictor of all-cause mortality in patients with advanced ischemic cardiomyopathy, after adjusting for clinical risk factors, severity of ischemic mitral regurgitation, incomplete revascularization, and device therapy.', 'A total of 362 patients with ischemic cardiomyopathy (left ventricular dysfunction with >70% stenosis in ≥1 epicardial coronary artery) underwent delayed hyperenhancement-magnetic resonance imaging and coronary angiography between 2002 and 2006. Total myocardial scar and peri-infarct (PI) area were measured using various threshold techniques. Multivariate survival analysis (primary end point of all-cause mortality) was conducted. One hundred fifty-seven deaths occurred during a mean 5.4-year follow-up (mean left ventricular ejection fraction, 23±9%; mean end-systolic volume index, 113±48 mL; mean total myocardial scar %, 25.5±16.0%; mean PI%, 5.7±2.9%). PI% (β=2.07; P<0.001) was an independent predictor of survival, independent of age, end-systolic volume, sex, mitral regurgitation, diabetes mellitus, dyslipidemia, coronary artery disease severity, implantable cardioverter defibrillator, and incomplete revascularization. PI% using 2 to 3 SD technique yielded the highest incremental prognostic power (χ(2) score 149).

Example Input: Acute promyelocytic leukemia (APL) is a sub-type of acute myeloid leukemia (AML) characterized by a block of myeloid differentiation at the promyelocytic stage and the predominant t(15:17) chromosomal translocation. We have previously determined that cells from APL patients show increased expression of genes regulated by hypoxia-inducible transcription factors (HIFs) compared to normal promyelocytes. HIFs regulate crucial aspects of solid tumor progression and are currently being implicated in leukemogenesis.', "To investigate the contribution of hypoxia-related signaling in APL compared to other AML sub-types, we reverse engineered a transcriptional network from gene expression profiles of AML patients' samples, starting from a list of direct target genes of HIF-1. A HIF-1-dependent subnetwork of genes specifically dysregulated in APL was derived from the comparison between APL and other AMLs.", 'Interestingly, this subnetwork shows a unique involvement of genes related to extracellular matrix interaction and cell migration, with decreased expression of genes involved in cell adhesion and increased expression of genes implicated in motility and invasion, thus unveiling the presence of characteristics of epithelial-mesenchymal transition (EMT). We observed that the genes of this subnetwork, whose dysregulation shows a peculiar pattern across different AML sub-types, distinguish malignant from normal promyelocytes, thus ruling out dependence on a myeloid developmental stage. Also, expression of these genes is reversed upon treatment of APL-derived NB4 cells with all-trans retinoic acid and cell differentiation.

Example Input: Organic cation transporters 1-3 (OCT1-3; Slc22a1-3) mediate the membrane transport of organic cations in the kidney. We previously reported that rat (r)OCT2 expression in the kidney was regulated by testosterone. In this study, we examined the transcriptional mechanisms underlying the testosterone-dependent regulation of rOCT2 expression.', 'Approximately 3000-bp fragments of the rOCT1-3 promoter region were isolated, and promoter activities were measured in the renal epithelial cell line LLC-PK1 with the coexpression of rat androgen receptor.', 'Among reporter constructs tested, only rOCT2 promoter activity was stimulated by testosterone. This stimulation was suppressed by nilutamide, an antiandrogen drug. Reporter assays using deletion constructs and mutational constructs of putative androgen response elements (ARE) in the rOCT2 promoter region suggested that two AREs, located at approximately -3000 and -1300, respectively, play an important role in the induction by testosterone.
