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.

Q: To determine if adolescents with unilateral hearing loss (UHL) demonstrate worse language skills than their siblings with normal hearing (NH).', 'Case-control study of 12-17-year-old adolescents with UHL (20 cases) compared with sibling controls with NH (13 controls).', "Scores on the oral portion of the Oral and Written Language Scales (OWLS) and the Clinical Evaluation of Language Fundamentals (CELF) were the primary outcome measure. Wechsler's Abbreviated Scales of Intelligence (WASI) scores were also used as an outcome measure.", 'Adolescents with UHL demonstrated worse overall and expressive language scores than controls, (98 vs. 114, P=0.001; 100 vs. 114, P=0.006) and had significantly lower full scale (98 vs. 112, P=0.017), verbal (101 vs. 113, P=0.032), and performance IQ (95 vs. 107, P=0.037).

Q: To describe the novel use of a chorioretinal biopsy technique to confirm the microbiological diagnosis of endogenous Escherichia coli (E. coli) endophthalmitis, when other investigations have been proven nondiagnostic.', 'Case report of an 82-year-old white man with endogenous endophthalmitis without a clearly identifiable source of infection.', 'After systemic cultures and multiple aqueous and vitreous samples were unable to identify a causative organism, chorioretinal biopsy of a subretinal abscess was used to confirm the microbiological diagnosis. This ensured appropriate ophthalmic and systemic treatment of infection.

Q: We have previously shown that the cardioprotective effect of ischemic preconditioning (IPC) is suppressed in hyperhomocysteinemic rat hearts. The present study investigated the effect of 2-chloro-N-cyclopentyladenosine (CCPA), a selective adenosine-A1 receptor agonist, in hyperhomocysteinemia-induced attenuation of the cardioprotective effect of IPC.', 'Rats were administered L-methionine (1.7 g/kg/day po) for 8 weeks to produce hyperhomocysteinemia. Isolated Langendorff perfused normal and hyperhomocysteinemic rat hearts were subjected to 30-minute global ischemia, followed by a 120-minute reperfusion. Myocardial infarct size was assessed macroscopically using triphenyltetrazolium chloride staining. Coronary effluent was analyzed for lactate dehydrogenase and CK-MB release to assess the extent of cardiac injury. The oxidative stress in the heart was assessed by measuring thiobarbituric acid reactive substance and reduced form of glutathione.', 'Ischemia and reperfusion (I/R) produced myocardial injury by increasing myocardial infarct size, elevating lactate dehydrogenase and CK-MB release in coronary effluent, decreasing coronary flow rate, and inducing oxidative stress in normal and hyperhomocysteinemic rat hearts. The hyperhomocysteinemic rat hearts showed enhanced I/R-induced myocardial injury with high oxidative stress. The IPC afforded cardioprotection against I/R-induced myocardial injury in normal rat hearts. However, IPC-mediated myocardial protection against I/R injury was abolished in hyperhomocysteinemic rat hearts. Administration of CCPA did not alter the cardioprotective effect of IPC in normal rat hearts, but its administration markedly restored the cardioprotective effect of IPC in hyperhomocysteinemic rat hearts.
