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: Elevated levels of EMMPRIN/CD147 in cancer tissues have been correlated with tumor progression but the regulation of its expression is not yet understood. Here, the regulation of EMMPRIN expression was investigated in testicular germ cell tumor (TGCTs) cell lines.', 'EMMPRIN expression in seminoma JKT-1 and embryonal carcinoma NT2/D1 cell lines was determined by Western blot, immunofluorescence and qRT-PCR. Membrane vesicles (MVs) secreted from these cells, treated or not with EMMPRIN siRNA, were isolated by differential centrifugations of their conditioned medium. MMP-2 was analyzed by zymography and qRT-PCR.', 'The more aggressive embryonic carcinoma NT2/D1 cells expressed more EMMPRIN mRNA than the seminoma JKT-1 cells, but surprisingly contained less EMMPRIN protein, as determined by immunoblotting and immunostaining. The protein/mRNA discrepancy was not due to accelerated protein degradation in NT2/D1 cells, but by the secretion of EMMPRIN within MVs, as the vesicles released from NT2/D1 contained considerably more EMMPRIN than those released from JKT-1. EMMPRIN-containing MVs obtained from NT2/D1, but not from EMMPRIN-siRNA treated NT2/D1, increased MMP-2 production in fibroblasts to a greater extent than those from JKT-1 cells.

Example Input: Several studies have reported that ventriculoperitoneal shunt insertion for treatment of normal-pressure hydrocephalus results in improvement of gait and, less frequently, improvement of cognition. We sought to identify the demographic factors associated with cognitive improvement after shunt insertion to improve assessment of prognosis for cognitive gains with treatment.', 'We report cognitive testing before and after ventriculoperitoneal shunt insertion in 36 patients with normal pressure hydrocephalus, who previously had improvement of any clinical symptom--gait, urinary incontinence, cognition--after a diagnostic trial of continuous cerebrospinal fluid drainage.

Example Input: Although diabetic patients often have gastrointestinal complications, the gastric mucosal function in diabetes has not been well documented.', 'To investigate the effect of fasting on the gastric mucosa in C57BL/KsJ-db +/+ db (db/db) mice, genetically non-insulin-dependent diabetic animals.', 'Blood glucose levels, gastric mucosal morphology, and the amount of gastric mucin were examined before and after 18 h of fasting with free access to water in db/db mice and their non-diabetic littermates (db/m).', 'Although 18 h of fasting reduced the blood glucose levels of both db/db and db/m mice, fasting decreased the amount of gastric adherent mucin and caused haemorrhagic gastric lesions only in db/db mice. After fasting, oral administration of ethanol induced much more severe gastric damage in db/db than in db/m mice. The above fasting-induced gastric damage such as haemorrhagic lesions, loss of the mucin, and the increased sensitivity to ethanol worsened as the duration of diabetes became longer. Glucose ingestion in drinking water during the fasting counteracted the fall in blood glucose and prevented the decrease in the amount of gastric mucin and the formation of gastric mucosal lesions in db/db mice.
