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: Sirtuin 3 (Sirt3), one of the seven Sirtuins family members, plays critical roles in the progression of multiple cancer types. However, its role in the prognosis of hepatocellular carcinoma (HCC) has not yet been investigated systematically.', 'The correlation of Sirtuins expression with prognosis of HCC was determined by immunohistochemistry (IHC) in a large HCC patient cohort (n = 342). Expression of Sirt3 in tumoral and peritumoral tissues of HCC patients were further determined by western blotting (WB).', 'IHC and WB studies both showed a decreased expression of Sirt3 in tumoral tissues compared with peritumoral tissues (P = 0.003 for IHC, P = 0.0042 for WB). Decreased expression of Sirt3 in both tumoral and peritumoral tissues was associated with increased recurrence probability and decreased overall survival rate by univariate analyses (intratumoral Sirt3: P = 0.011 for TTR, P = 0.001 for OS; peritumoral Sirt3: P = 0.017 for TTR, P = 0.023 for OS), the prognostic value was strengthened by multivariate analyses (intratumoral Sirt3: P = 0.031 for TTR, P = 0.001 for OS; peritumoral Sirt3: P = 0.047 for TTR, P = 0.031 for OS). Intratumoral Sirt3 also showed a favorable prognostic value in patients with BCLC stage A (TTR, P = 0.011; OS, P < 0.001). In addition, we found that IHC studies of other sirtuin members showed a decreased expression of Sirt2, Sirt4 and Sirt5 and an increased expression of Sirt1, Sirt6 and Sirt7 in intratumoral tissues compared with peritumoral tissues. In contrast to Sirt3, other members did not showed a remarkable correlation with HCC prognosis.

Example Input: The evidence on the prognostic value of transthoracic echocardiography (TTE) in elderly, hemodynamically stable patients with Pulmonary Embolism (PE) is limited.', 'To evaluate the prevalence of common echocardiographic signs of right ventricular (RV) dysfunction and their prognostic impact in hemodynamically stable patients aged 65years with acute PE in a prospective multicenter cohort.', 'TTE was performed by cardiologists. We defined RV dysfunction as a RV/left ventricular ratio >0.9 or RV hypokinesis (primary definition) or the presence of 1 or 2 of 6 predefined echocardiographic signs (secondary definitions). Outcomes were overall mortality and mortality/non-fatal recurrent venous thromboembolism (VTE) at 30days, adjusting for the Pulmonary Embolism Severity Index risk score and highly sensitive troponin T values.', 'Of 400 patients, 36% had RV dysfunction based on our primary definition, and 81% (1 sign) and 53% (2 signs) based on our secondary definitions, respectively. Using our primary definition, there was no association between RV dysfunction and mortality (adjusted HR 0.90, 95% CI 0.31-2.58) and mortality/non-fatal VTE (adjusted HR 1.09, 95% CI 0.40-2.98). Similarly, there was no statistically significant association between the presence of 1 or 2 echocardiographic signs (secondary definitions) and clinical outcomes.

Example Input: microRNAs (miRNAs) are short RNAs that regulate gene expression in various processes, including immune response. Altered immune response is a pivotal event in the pathogenesis of celiac disease (CD), and miRNAs could have a role in modulating both innate and adaptive response to gluten in celiac patients.', 'We compared miRNA profiles in duodenal biopsies of controls and CD patients by miRNA array. Differentially expressed miRNAs were validated in controls, Marsh 3A-B, and Marsh 3C patients by quantitative PCR (qPCR). Target gene expression was assessed by qPCR, western blotting, and immunohistochemistry, and the effect of gliadin was evaluated by in vitro stimulation experiments on duodenal biopsies.', 'Seven miRNAs were identified as significantly downregulated in the duodenum of adult CD patients as compared with controls. qPCR validated the decreased expression of miR-192-5p, miR-31-5p, miR-338-3p, and miR-197, in particular in patients with more severe histological lesions (Marsh 3C). In silico analysis of possible miRNA targets identified several genes involved in innate and adaptive immunity. Among these, chemokine C-X-C motif ligand 2 (CXCL2) and NOD2 showed significantly increased mRNA and protein level in Marsh 3C patients and a significant inverse correlation with the regulatory miR-192-5p. In addition, forkhead box P3 (FOXP3), Run-related transcription factor 1, and interleukin-18 (targets of miR-31-5p, miR-338-3p, and miR-197, respectively) showed upregulation in CD patients. Furthermore, alterations in CXCL2 and NOD2, FOXP3, miR-192-5p, and miR-31-5p expression were triggered by gliadin exposure in CD patients.
