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.

Example Input: To compare the efficacy of intensity-modulated radiotherapy, three-dimensional conformal radiotherapy, and conventional radiotherapy for cervical cancer treatment.', 'Whole pelvis intensity-modulated radiotherapy, three-dimensional conformal radiotherapy, and conventional radiotherapy plans were designed for 16 patients with stage IIB cervical cancer, each using the prescribed dose of 50.4 Gy/28 fractions. Dose-volume histograms of the target volume and organs at risk were evaluated.', 'Compared to the 3D conformal and conventional radiotherapy plans, the intensity-modulated radiotherapy plan demonstrated superior conformal treatment. The mean planning target volume dose of all three plans reached the target effective therapeutic dose. The planning target volume dose of the intensity-modulated radiotherapy plan was significantly higher than that of either the three-dimensional conformal radiotherapy or conventional radiotherapy plan (P<0.05). When more than 30 Gy was administered in intensity-modulated radiotherapy, organs at risk including the small intestine, rectum, bladder, and bone marrow received a significantly reduced volume of radiation. In comparison of the average planning target volume doses, significant volume reductions in irradiation of organs at risk were obtained with full bladders.

Example Input: The regulatory mechanisms of IL-5 gene transcription in human peripheral T cells are unclear because the transfection efficiency of plasmid constructs into nontransformed T cells is very low.', 'Concanavalin A (ConA)-stimulated blastocytes derived from peripheral blood lymphocytes of asthmatic subjects were transiently transfected with the human IL-5 gene promoter/enhancer-luciferase gene construct, pIL-5 (-511)Luc, and cultured with THP-1 cells (human monocytoid cells) and anti-CD3 monoclonal antibody (mAb). IL-5 level in the culture medium was determined by an enzyme-linked immunosorbent assay. Transcriptional activity of the IL-5 gene was measured by luciferase reporter analysis.', "ConA-blast lymphocytes of asthmatic patients produced a significant amount of IL-5 upon combined stimulation with anti-CD3 mAb and THP-1 cells, but not with anti-CD3 mAb alone. Costimulation with anti-CD28 mAb also enhanced the anti-CD3 mAb- induced IL-5 production. Accordingly, luciferase activity induced by anti-CD3 mAb stimulation in pIL-5(-511)Luc-transfected ConA-blast lymphocytes was increased 1.9- and 3.4-fold by the addition of anti-CD28 mAb and THP-1 cells, respectively. Serial 5' deletion analysis of the reporter gene demonstrated that the cis-regulatory element located at -119 to -80 is critical for anti-CD3 mAb-induced IL-5 gene transcription.

Example Input: Adipose tissue derived-mesenchymal stem cells (AMSCs) are one of the most widely used MSCs in the cell therapy for regenerative medicine. In the current study, the role of CXCL13 in AMSCs and its potential signaling pathway were investigated.', 'AMSCs were isolated from adipose tissue of healthy subjects. After administrating the cells with CXCL13, the expression levels of miR-23a and runt-related transcription factor 2 (Runx2) were assessed by real-time PCR and western blot. The alterations of phosphoinositide-3 kinase (PI3K)/Akt, stress-activated protein kinase (SAPK)/c-jun kinase (JNK), and extracellular-signal-regulated kinase (ERK1/2) pathways were also evaluated.', 'CXCL13 down-regulated miR-23a and up-regulated Runx2 expression in AMSCs. The inhibitor specific for PI3K/AKT, but not SAPK/JNK and ERK ERK1/2, reversed the effects of CXCL13 on miR-23a and Runx2 expression.
