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]: Splenectomy is a clinical risk factor for complicated thrombosis. We hypothesized that the loss of the mechanical filtering function of the spleen may enrich for thrombogenic phospholipids in the circulation, thereby affecting the vascular remodeling of thrombosis.', 'We investigated the effects of splenectomy both in chronic thromboembolic pulmonary hypertension (CTEPH), a human model disease for thrombus nonresolution, and in a mouse model of stagnant flow venous thrombosis mimicking deep vein thrombosis. Surgically excised thrombi from rare cases of CTEPH patients who had undergone previous splenectomy were enriched for anionic phospholipids like phosphatidylserine. Similar to human thrombi, phosphatidylserine accumulated in thrombi after splenectomy in the mouse model. A postsplenectomy state was associated with larger and more persistent thrombi. Higher counts of procoagulant platelet microparticles and increased leukocyte-platelet aggregates were observed in mice after splenectomy. Histological inspection revealed a decreased number of thrombus vessels. Phosphatidylserine-enriched phospholipids specifically inhibited endothelial proliferation and sprouting.

[Q]: This study used dopamine D2 receptor (D2R) knockout (KO) mice to investigate the role of D2R activity in the development of form-deprivation myopia (FDM). Sulpiride, a D2R antagonist, was administered systemically into wild-type (WT) mice to validate the involvement of D2R in FDM development.', 'The D2R KO and WT C57BL/6 mice were subjected to FDM. Wild-type mice received daily intraperitoneal injections of sulpiride, 8 μg/g body weight, for a period of 4 weeks. The body weight, refraction, corneal radius of curvature, and ocular axial components were measured at week 4 of the experiment. Differences in all ocular parameters between the experimental and control groups were compared statistically.', 'Form-deprivation myopia in D2R KO mice (FD-KO) was significantly reduced compared with their WT littermates (interocular difference, -2.12 ± 0.91 diopter [D] in FD-KO versus -5.35 ± 0.83 D in FD-WT, P = 0.014), with a smaller vitreous chamber depth (0.008 ± 0.006 vs. 0.026 ± 0.006 mm, P = 0.044) and axial length (-0.001 ± 0.007 vs. 0.027 ± 0.008 mm, P = 0.007). Furthermore, FDM was attenuated in animals treated with sulpiride (-2.01 ± 0.31 D in FD-sulpiride versus -4.06 ± 0.30 D in FD-DMSO, P < 0.001) compared with those treated with vehicle, with a retardation in growth of vitreous chamber depth (-0.001 ± 0.006 vs. 0.022 ± 0.004 mm, P = 0.003) and axial length (-0.004 ± 0.007 vs. 0.027 ± 0.005 mm, P = 0.001).

[Q]: Lamin A and C are nuclear filament proteins encoded by the LMNA gene. Mutations in the LMNA gene cause many congenital diseases known as laminopathies, including Emery-Dreifuss muscular dystrophy, Hutchinson-Gilford progeria syndrome, and familial dilated cardiomyopathy (DCM) with conduction disease. A missense mutation (N195K) in the A-type lamins results in familial DCM and sudden arrhythmic death.', 'The purpose of this study was to investigate the ion current mechanism of arrhythmia and DCM caused by the LaminA-N195K variant.', 'A homozygous mouse line expressing the Lmna-N195K mutation (Lmna', 'Both peak and late I
