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.

[EX Q]: This study aimed to evaluate the long-term outcomes and the soft-tissue response to osseous genioplasty in patients with chin retrusion caused by early life facial burn injury.', 'Twenty-two consecutive patients with retrusive chin as a result of severe childhood facial burn were included in this study. Cephalometric analysis and photographs were used to assess the patients for eligibility of a surgical correction. Horizontal hard-tissue advancement and soft-tissue responses were measured as the primary outcomes at the early and late postoperative follow-up visits.', 'A total of 22 patients fulfilled the study requirements. Average preoperative distance between the pogonion, as the most anterior point of the anterior mandibular contour, and a perpendicular line connecting the nasion and the supramental point of the mandible was 0.82 1.1 mm, which increased significantly to 7.8 0.8 mm after genioplasty (p < 0.0001). Soft tissue was repositioned on average 6.1 0.4 mm anteriorly on average, which is in comparison with the amount of chin skeleton advancement, and a response ratio of 0.8:1 was calculated at late follow-up.

[EX 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=5.69E-07) and 69% (P=2.00E-04) in treated ApoE- and ApoE/GPx1-deficient mice, respectively. A 40% reduction in plaque (P=7.74E-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=2.43E-02) in the aortic sinus and nitrotyrosine staining (-78%, P=5.11E-06) in the aorta.

[EX Q]: Perchlorate is an environmental contaminant that blocks iodine uptake into the thyroid gland and reduces thyroid hormones. This action of perchlorate raises significant concern over its effects on brain development.', 'The purpose of this study was to evaluate neurologic function in rats after developmental exposure to perchlorate.', 'Pregnant rats were exposed to 0, 30, 300, or 1,000 ppm perchlorate in drinking water from gestational day 6 until weaning. Adult male offspring were evaluated on a series of behavioral tasks and neurophysiologic measures of synaptic function in the hippocampus.', 'At the highest perchlorate dose, triiodothyronine (T(3)) and thyroxine (T(4)) were reduced in pups on postnatal day 21. T(4) in dams was reduced relative to controls by 16%, 28%, and 60% in the 30-, 300-, and 1,000-ppm dose groups, respectively. Reductions in T(4) were associated with increases in thyroid-stimulating hormone in the high-dose group. No changes were seen in serum T(3). Perchlorate did not impair motor activity, spatial learning, or fear conditioning. However, significant reductions in baseline synaptic transmission were observed in hippocampal field potentials at all dose levels. Reductions in inhibitory function were evident at 300 and 1,000 ppm, and augmentations in long-term potentiation were observed in the population spike measure at the highest dose.
