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]: To explore the antitumor effect of prescription consisting of Vitamin C (Vc) and Baicalin (PVB).', 'To explore the antitumor effect of PVB, using U14 cervical tumor-bearing mice model was used and the drugs were administrated through the gavages. Spectrophotometry was used to determine the content of superoxide dismutase (SOD), malondialdehyde (MDA) and cytokines IL-2, Il-4 and IFN-γ.', 'PVB had a better antitumor effect than baicalin and Vc used alone with an inhibition rate of 58.18% (p<0.05); PVB significantly improved the spleen index (p<0.01), and significantly reduced MDA content (p<0.01) but increased SOD activity in liver tissue and serum (p<0.01).

[EX Q]: Little is known about endothelial function in adolescents with type 1 diabetes, and we evaluated endothelial dysfunction, using reactive hyperaemia peripheral arterial tonometry (RH-PAT).', 'This prospective, observational, 1-year study focused on 73 adolescents with type 1 diabetes, using multiple daily injections or continuous subcutaneous insulin infusion. The subjects were assessed using RH-PAT, body mass index, blood pressure, fasting lipid profile, glycated haemoglobin, insulin requirements and hours of physical exercise per week.', 'Endothelial dysfunction was observed in 56 patients (76.7%), with lower mean RH-PAT scores (1.26\xa0±\xa00.22 versus 2.24\xa0±\xa00.48, p\xa0<\xa00.0001) and higher glycated haemoglobin values at baseline (8.27\xa0±\xa01.24% versus 7.37\xa0±\xa00.54%, p\xa0=\xa00.006) and as a mean of the whole period since diagnosis (8.25\xa0±\xa01.22% versus 7.72\xa0±\xa00.82%, p\xa0=\xa00.034). A higher percentage of patients with endothelial dysfunction showed abnormal cardiac autonomic tests (p\xa0=\xa00.02) and were more sedentary, exercising <4 hours a week, than patients with normal endothelial function. After follow-up in 64/73 patients, we observed endothelial dysfunction in 81.8% of patients, despite a modest improvement in glycated haemoglobin.

[EX Q]: Large mega base-pair genomic regions show robust alterations in DNA methylation levels in multiple cancers. A vast majority of these regions are hypomethylated in cancers. These regions are generally enriched for CpG islands, Lamin Associated Domains and Large organized chromatin lysine modification domains, and are associated with stochastic variability in gene expression. Given the size and consistency of hypomethylated blocks (HMB) across cancer types, we hypothesized that the immediate causes of methylation instability are likely to be encoded in the genomic region near HMB boundaries, in terms of specific genomic or epigenomic signatures. However, a detailed characterization of the HMB boundaries has not been reported.', 'Here, we focused on ~13 k HMBs, encompassing approximately half of the genome, identified in colon cancer. We modeled the genomic features of HMB boundaries by Random Forest to identify their salient features, in terms of transcription factor (TF) binding motifs. Additionally we analyzed various epigenomic marks, and chromatin structural features of HMB boundaries relative to the non-HMB genomic regions.', 'We found that the classical promoter epigenomic mark--H3K4me3, is highly enriched at HMB boundaries, as are CTCF bound sites. HMB boundaries harbor distinct combinations of TF motifs. Our Random Forest model based on TF motifs can accurately distinguish boundaries not only from regions inside and outside HMBs, but surprisingly, from active promoters as well. Interestingly, the distinguishing TFs and their interacting proteins are involved in chromatin modification. Finally, HMB boundaries significantly coincide with the boundaries of Topologically Associating Domains of the chromatin.
