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]: Migraine is associated with epilepsy, but the time order and nature of the relationship are unclear. We conducted a population based case control study to clarify the time order to determine whether migraine is a risk factor for epilepsy.', 'Migraine symptoms were evaluated in a population-based case-control study of all incident epilepsy in Icelandic children and in matched controls (next two same sex births in the country).', 'Migraine was associated with a fourfold increased risk for developing epilepsy, an association explained by migraine with aura (odds ratio, 8.1; 95% confidence interval, 2.7-24.3). Migraine without aura did not increase risk for epilepsy.

[Q]: We previously reported a negative association of circulating plasmalogens (phospholipids with proposed atheroprotective properties) with coronary artery disease. Plasmalogen modulation was previously demonstrated in animals but its effect on atherosclerosis was unknown. We assessed the effect of plasmalogen enrichment on atherosclerosis of murine models with differing levels of oxidative stress.', 'Six-week old ApoE- and ApoE/glutathione peroxidase-1 (GPx1)-deficient mice were fed a high-fat diet with/without 2% batyl alcohol (precursor to plasmalogen synthesis) for 12 weeks. Mass spectrometry analysis of lipids showed that batyl alcohol supplementation to ApoE- and ApoE/GPx1-deficient mice increased the total plasmalogen levels in both plasma and heart. Oxidation of plasmalogen in the treated mice was evident from increased level of plasmalogen oxidative by-product, sn-2 lysophospholipids. Atherosclerotic plaque in the aorta was reduced by 70% (P\xa0=\xa05.69E-07) and 69% (P\xa0=\xa02.00E-04) in treated ApoE- and ApoE/GPx1-deficient mice, respectively. A 40% reduction in plaque (P\xa0=\xa07.74E-03) was also seen in the aortic sinus of only the treated ApoE/GPx1-deficient mice. Only the treated ApoE/GPx1-deficient mice showed a decrease in VCAM-1 staining (-28%, P\xa0=\xa02.43E-02) in the aortic sinus and nitrotyrosine staining (-78%, P\xa0=\xa05.11E-06) in the aorta.

[Q]: Viral infections are associated with both mild and severe exacerbations of asthma and may therefore be associated with asthma death. As such we hypothesized that it might be possible to detect rhinovirus (RV), the virus most frequently implicated in acute asthma, in lung tissue from patients who died from asthma.', 'We studied archival, wax-embedded lung tissue obtained postmortem from: (i) patients who died from asthma (n = 12), (ii) asthma patients with non-asthma-related death (n = 3), and (iii) non-asthmatic individuals who died from unrelated causes (n = 3). A validated reverse transcription-polymerase chain reaction (RT-PCR) assay was used to detect RV. To confirm RNA preservation, RT-PCR was used to detect expression of the constitutive gene adenine-phosphoribosyl-transferase (APRT). Sensitivity of the assay was assessed using wax-embedded RV-infected cells.', 'Sensitivity of RT-PCR for RV in wax-embedded sections was similar to previous studies (approximately 100 viral copies). Specimens used for study were predominantly of alveolar and small airway origin (< 2 mm). All tissues examined were negative for the presence of RV mRNA and positive for APRT mRNA.
