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: Growth factor therapy provides a therapeutic alternative for "no option" patients with coronary disease. Fibroblast Growth Factor-2 (FGF-2) predominantly stimulates angiogenesis, the growth of new capillaries, whereas Monocyte Chemoattractant Protein-1 (MCP-1) is considered an arteriogenic agent. We hypothesised a synergetic effect of FGF-2 and MCP-1 in ischemic myocardium.', 'A severe coronary stenosis was created in pigs. After one week, chronic ischemia was confirmed by angiography, echocardiography, reduced ejection fraction, and increase of marker enzymes. FGF-2, MCP-1, both, or vector only were then injected intramyocardially as plasmid DNA in the impaired area. Regional contractility and number of capillaries and arterial vessels were evaluated after three months.', 'FGF-2, FGF-2+MCP-1, and vector, but not MCP-1 alone improved regional contractility at rest, whereas only FGF-2 alone ameliorated function under stress conditions. Angiogenesis in the ischemic area was stimulated by FGF-2 compared to MCP-1. In contrast, MCP-1 induced arteriogenesis relative to FGF-2.

Input: Consider Input: Depression is the most common psychiatric comorbidity in epilepsy patients. The lack of success with current pharmacological interventions for this patient population, highlights the importance of optimizing non-pharmacological neuromodulatory treatments such as vagus nerve stimulation (VNS). Studies on the antidepressant effect of VNS in epilepsy patients may be confounded by concurrent anti-epileptic drug therapy. To date, studies in epilepsy models overcoming this problem are lacking.', 'We investigated whether VNS affects anhedonia, a key symptom of major depression, in the kainic acid rat model for temporal lobe epilepsy.', 'Anhedonia was assessed in kainic acid (KA) and saline (SAL) injected rats using the saccharin preference test (SPT). To exclude differences in taste perception, the quinine aversion test (QAT) was performed. Both groups were randomly subdivided in a VNS and a SHAM group, yielding 4 experimental arms: KA-VNS, KA-SHAM, SAL-VNS and SAL-SHAM. Both VNS groups received 2 weeks of VNS, while the SHAM groups were not stimulated. Thereafter, the SPT and QAT were repeated.', 'Saccharin preference was significantly reduced in the KA compared to the SAL rats (P\xa0<\xa00.05), without differences in quinine aversion. Two weeks of VNS significantly increased the saccharin preference in the KA-VNS group (P\xa0<\xa00.05), while it had no effect on quinine aversion. No effects of VNS or SHAM were found in the other groups.

Input: Consider Input: To investigate the mutation status of growth differentiation factor 15 (GDF15) in patients with oral squamous cell carcinoma (OSCC), as well as the prognostic value of missense GDF15 mutations.', 'Formalin-fixed paraffin-embedded biopsy samples from 46 OSCC patients were involved in this study. GDF15 and TP53 mutations were sequenced using the Ion Torrent Personal Genome Machine, GDF15 protein expression was detected using immunohistochemistry. Torrent Suite Software v.3.6, Integrative Genomics Viewer; v.2.3, statistical software SPSS18.0 for Windows were used for analysis. All hypothesis-generating tests were two-sided at a significance level of 0.05.', 'Twenty-nine GDF15 mutations were identified in 19 out of 46 patients (41.3%), including eighteen missense mutations, two nonsense mutations and nine synonymous mutations. The patients with missense GDF15 mutations had poorer prognostic outcomes than those with wild-type GDF15, including overall survival (P = 0.035), disease-free survival (P = 0.032), locoregional recurrence-free survival (P = 0.015), and distant metastasis-free survival (P = 0.070). Missense GDF15mutations was an independent increased risk factor of overall survival (HR = 5.993, 95% CI:1.856-19.346, P = 0.003), disease-free survival (HR = 3.764, 95% CI:1.295-10.945, P = 0.015), locoregional recurrence-free survival (HR = 4.555, 95% CI:1.494-13.889, P = 0.008), and distant metastasis-free survival (HR = 4.420, 95% CI:1.145-13.433, P = 0.009).
