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]: Obesity has shown a positive association with depression. We aimed to investigate the relationships among body weight, body mass index (BMI=kg/m(2)), change in a depression rating scale, and change in a functional scale with fluoxetine treatment for hospitalized patients with major depressive disorder (MDD).', 'A total of 131 acutely ill inpatients with MDD were enrolled to receive 20mg of fluoxetine daily for 6 weeks. The 17-item Hamilton Depression Rating Scale (HAMD-17) for symptom and the Work and Social Adjustment Scale (WSAS) for functioning were assessed at weeks 0, 1, 2, 3, 4, and 6. Remission was defined as a score of≤7 on the HAMD-17 at endpoint. Body weight, body length, and BMI were measured at baseline. Pearson correlation coefficients (r) were calculated among body weight, BMI, HAMD-17 score change, and WSAS score change.', 'Of the 131 participants, 126 (96.2%) had at least one post-baseline assessment and were included in the analysis. Significant differences in body weight and BMI existed between remitters and nonremitters. There were statistically significant relationships among baseline body weight, baseline BMI, HAMD-17 score change, and WSAS score change at end point.

[EX Q]: Acute promyelocytic leukemia (APL) is a sub-type of acute myeloid leukemia (AML) characterized by a block of myeloid differentiation at the promyelocytic stage and the predominant t(15:17) chromosomal translocation. We have previously determined that cells from APL patients show increased expression of genes regulated by hypoxia-inducible transcription factors (HIFs) compared to normal promyelocytes. HIFs regulate crucial aspects of solid tumor progression and are currently being implicated in leukemogenesis.', "To investigate the contribution of hypoxia-related signaling in APL compared to other AML sub-types, we reverse engineered a transcriptional network from gene expression profiles of AML patients' samples, starting from a list of direct target genes of HIF-1. A HIF-1-dependent subnetwork of genes specifically dysregulated in APL was derived from the comparison between APL and other AMLs.", 'Interestingly, this subnetwork shows a unique involvement of genes related to extracellular matrix interaction and cell migration, with decreased expression of genes involved in cell adhesion and increased expression of genes implicated in motility and invasion, thus unveiling the presence of characteristics of epithelial-mesenchymal transition (EMT). We observed that the genes of this subnetwork, whose dysregulation shows a peculiar pattern across different AML sub-types, distinguish malignant from normal promyelocytes, thus ruling out dependence on a myeloid developmental stage. Also, expression of these genes is reversed upon treatment of APL-derived NB4 cells with all-trans retinoic acid and cell differentiation.

[EX Q]: Tumour cells alter the characteristics of the adjacent stroma to create a supportive microenvironment during cancer progression. In vitro and in vivo experiments were carried out to verify the role of stromal TGF-β1 in reinforcing of the invasive potential in low invasive cancer.', 'Isolated NF or CAF was co-cultured with low invasive HSC-2 cells to evaluate whether stromal TGF-β1 induced PDPN expression by Transwell invasion and influenced tumour growth in orthotopic xenografts.', 'Stimulation by TGF-β1 promoted PDPN expression and Transwell invasion through SMAD signalling as well as activation of Src, P38 mitogen activated protein kinase and extracellular regulated kinase 1/2. PDPN induction was TβRII-dependent. Tumour growth of HSC-2 OSCC in a mouse xenograft was intensified in the tumour CAF microenvironment.
