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: SUMO-specific protease 1 (SENP1) removes SUMO from proteins and plays important roles in the regulation of multiple cellular signalling pathways. However, little is known about the role of SENP1 in coronary heart disease. In this study, we tested the hypothesis that SENP1 protects against myocardial ischaemia/reperfusion (I/R) injury and investigated the underlying molecular mechanisms involved.', 'First, we found that SENP1 levels increased after I/R in human and mouse myocardium in vivo and in rat cardiomyocytes in vitro. We then performed coronary artery ligation to induce I/R injury in wild-type (WT) and heterozygous SENP1-knockdown (SENP1(+/-)) mice. Compared with WT mice, SENP1(+/-) mice had normal cardiac function at baseline but lower systolic function after I/R. Post-I/R myocardial infarction sizes were larger in SENP1(+/-) mice. Furthermore, we demonstrated that SENP1 regulates the expression of hypoxia-inducible factor 1 α (HIF1α), a critical protective factor during I/R, in vivo and in vitro. Overexpression of HIF1α reversed the deteriorating effect of SENP1 knockdown on cellular death.

Example Input: To assess the effect of newborn circumcision on the incidence and medical costs of urinary tract infection (UTI) during the first year of life for patients in a large health maintenance organization.', 'Kaiser Permanente Medical Care Program of Northern California (KPNC).', 'The population consisted of members of KPNC. The study group consisted of a cohort of 28 812 infants delivered during 1996 at KPNC hospitals; of the 14 893 male infants in the group, 9668 (64.9%) were circumcised. A second cohort of 20 587 infants born in 1997 and monitored for 12 months was analyzed to determine incidence rates.', 'Retrospective study of all infants consecutively delivered at 12 facilities.', 'Diagnosis of UTI was determined from the KPNC computerized database using the International Classification of Diseases, Ninth Revision code for inpatients and KPNC Outpatient Summary Clinical Record codes for outpatients. A sample of 52 patient charts was reviewed to confirm the International Classification of Diseases, Ninth Revision and KPNC Outpatient Summary Clinical Record codes and provide additional data.', 'Infants <1 year old who were born in 1996 had 446 UTIs (292 in females; 154 in males); 132 (86%) of the UTIs in males occurred in uncircumcised boys. The mean total cost of managing UTI was 2 times as high in males ($1111) as in females ($542). This higher total cost reflected the higher rate of hospital admission in uncircumcised males with UTIs (27.3%) compared with females (7.5%); mean age at hospitalization for UTI was 2.5 months old for uncircumcised boys and 6.5 months old for girls. In 1996, total cost of managing UTI in uncircumcised males ($155 628) was 10 times higher than for circumcised males ($15 466) despite the fact that uncircumcised males made up only 35.1% of the male patient base in 1996, reflecting the more frequent occurrence of UTI in uncircumcised males (132 episodes) than in circumcised males (22 episodes), and the larger number of hospital admissions in uncircumcised males (38) than in circumcised males (4). The incidence of UTI in the first year of life was 1:47 (2.15%) in uncircumcised males, 1:455 (.22%) in circumcised males, and 1:49 (2. 05%) in females. The odds ratio of UTI in uncircumcised:circumcised males was 9.1:1.
