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.

Input: Consider Input: To determine whether all-trans retinoic acid or a synthetic retinoic acid receptor-/-specific agonist, Am80, can reduce the degree of experimental autoimmune optic neuritis in mice with experimental autoimmune encephalomyelitis.', 'Optic neuritis was induced in C57BL/6 mice by immunizing them with myelin oligodendrocyte glycoprotein35-55 . All-trans retinoic acid (350g/mouse/time point) or Am80 (5mg/kg/time point) was administered every other day from day 0 to day 20. The degree of experimental autoimmune encephalomyelitis was scored and histopathological analysis of the optic neuritis was performed on day 22 after the immunization. In vivo-primed draining lymph node cells obtained from vehicle-treated or all-trans retinoic acid-treated mice were stimulated with myelin oligodendrocyte glycoprotein35-55 , and the culture supernatant was collected for assays of interferon- and interleukin-17.', 'All-trans retinoic acid treatment significantly reduced the clinical score of experimental autoimmune encephalomyelitis and the severity of the optic neuritis by histopathological analysis. The production of interferon- and interleukin-17 was significantly reduced in all-trans retinoic acid-treated mice compared with vehicle-treated mice. Am80 treatment also significantly decreased the severity of the optic neuritis in mice with experimental autoimmune encephalomyelitis.

Input: Consider Input: To evaluate whether genotypes of interleukin (IL)-6 gene promoter positions -174 and -572 are associated with histologic chorioamnionitis and neonatal inflammatory disease in preterm infants.', 'DNA from very low birth weight or very preterm infants (n = 107) was genotyped for IL-6-174 and -572 polymorphisms (GG/GC/CC). The placentas were analyzed for histological inflammatory findings. Data on neonatal inflammatory diseases, including chronic lung disease (CLD), necrotizing enterocolitis (NEC), and septicemia, were collected using the definitions of the Vermont Oxford Network database.', 'In univariate analyses, the IL-6-174 GG genotype was associated with a higher incidence of histologic chorioamnionitis. In multivariate analyses, the -174 GG and -572 GC genotypes were correlated with histologic chorioamnionitis (P = .039 and .009, respectively). Gestational age was not associated with genotype polymorphisms. IL-6-174 genotypes were not associated with CLD and/or NEC, but the CC genotype was correlated with septicemia in both univariate and multivariate analyses (P = .027). IL-6-572 genotypes were not associated with neonatal inflammatory disease.

Input: Consider Input: Chemoresistance hinders curative cancer chemotherapy in osteosarcoma (OS), resulting in only an approximately 20% survival rate in patients with metastatic disease at diagnosis. Identifying the mechanisms responsible for regulating chemotherapy resistance is crucial for improving OS treatment.', 'This study was performed in two human OS cell lines (the multi-chemosensitive OS cell line G-292 and the multi-chemoresistant OS cell line SJSA-1). The levels of miR-20a-5p and KIF26B mRNA expression were determined by quantitative real-time PCR. KIF26B protein levels were determined by western blot analysis. Cell viability was assessed by MTT assay. Apoptosis was evaluated by flow cytometry.', "We found that miR-20a-5p was more highly expressed in G-292 cells than in SJSA-1 cells. Forced expression of miR-20a-5p counteracted OS cell chemoresistance in both cell culture and tumor xenografts in nude mice. One of miR-20a-5p's targets, kinesin family member 26B (KIF26B), was found to mediate the miR-20a-5p-induced reduction in OS chemoresistance by modulating the activities of the MAPK/ERK and cAMP/PKA signaling pathways.
