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: 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.

Input: Consider Input: Enhanced processing of emotional stimuli after stress exposure is reported to be associated with stress-induced cortisol. Because enhanced emotional information processing could make cognitive emotion regulation more difficult, it was hypothesized that stress-induced cortisol would be associated with non-negative interpretation generation associated with the cognitive reappraisal processes.', 'A total of 36 participants (Mean age=21.3years, SD=1.8) watched video clips of depression-related stressful situations before and after the administration of a stress induction task. They were then asked to generate as many non-negative interpretations as possible to reduce the depressive mood. Saliva samples were obtained before and after the stress induction task to measure change in the cortisol level.', 'Participants were allocated post-hoc to either a responder (n=19) or non-responder group (n=17) based on the cortisol response to the stress induction task. The number of non-negative interpretations generated following the stress induction task was reduced only in the cortisol responders. The number of post-stress non-negative interpretations was fewer in the responder group when compared by sex, baseline cortisol level, and the number of pre-stress non-negative interpretations, statistically controlled.

Input: Consider Input: A somatoanal reflex had been demonstrated in our previous work. Because nitric oxide plays an important role in mediating relaxation of the internal anal sphincter, our purpose was to examine whether and how local somatothermal stimulation inhibits the function of the internal anal sphincter by stimulating nitric oxide release via nitrergic neurons and to elucidate the possible mechanism.', 'The activity of the internal anal sphincter in anesthetized rabbits was measured by use of continuously perfused, open-tip manometric methods. Local somatothermal stimulation was achieved by applying an electroheating rod 1 cm away from the skin area at the right popliteal region. The responses were further manipulated by pre-treating the rabbits with agonists or antagonists linked to nitric oxide synthesis.', 'The motility of the internal anal sphincter before and during local somatothermal stimulation was significantly different (tonic pressure (mean +/-standard error of the mean), 5.4 +/- 0.3 vs. 4.9 +/- 0.3 mmHg, P = 0.0195; phasic pressure, 3.9 +/- 0.6 vs. 2.9 +/- 0.4 mmHg, P = 0.0002; frequency distribution of the phasic contractions (peak-to-peak interval), 28.9 +/- 3.7 vs. 65.3 +/- 10.4 seconds, P = 0.0001). The response began at approximately one minute after local somatothermal stimulation when the skin temperature was 41 +/- 0.3 degrees C. No anal response was observed when local somatothermal stimulation was applied at the control area. The local somatothermal stimulation-induced internal anal sphincter relaxation was not inhibited by pretreatment with atropine, propranolol, or phentolamine (tonic pressure, 5.8 +/- 1 vs. 5.2 +/- 0.8 mmHg, P = 0.038; phasic pressure, 4.2 +/- 0.9 vs. 3.1 +/- 0.6 mmHg, P = 0.020; peak-to-peak interval, 27.2 +/- 4.3 vs. 52.9 +/- 14.5 seconds, P = 0.043) but was completely blocked by pretreatment with a nitric oxide synthesis inhibitor. The effect of the nitric oxide synthesis inhibitor could be reversed by pretreatment with L-arginine (tonic pressure, 6 +/- 0.7 vs. 5.6 +/- 0.7 mmHg, P = 0.047; phasic pressure, 4.7 +/- 0.7 vs. 3.9 +/- 0.5 mmHg, P = 0.048; peak-to-peak interval, 23.8 +/- 3 vs. 33 +/- 3.7 seconds, P = 0.048), but not by D-arginine.
