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: Indoleamine 2,3 dioxygenase (IDO) degrades the essential amino acid tryptophan and has been shown to minimize rejection in animal models of renal transplantation. Ischemia-reperfusion injury (IRI) is unavoidable in renal transplantation and correlates with shorter graft survival times. Despite its favorable effects on rejection, there is evidence that IDO may facilitate renal IRI. Differentiating the negative impact of IDO on IRI from its pro-tolerant effects in allograft rejection is of clinical relevance. In these studies we hypothesized that constitutive IDO activity may influence renal genes associated with recovery from IRI, and that IDO inhibition may unmask these effects.', 'We examined the renal transcriptome in a rat model of IRI with and without IDO inhibition with 1-methyl-d-tryptophan (1-MT), and assessed for alterations in the gene expression signature.', 'These studies demonstrated that during recovery from renal IRI, pre-treatment with 1-MT alleviated alterations in 105 coding sequences associated with IRI, and in turn triggered new changes in 66 non-coding transcripts, the majority of which were represented by small nucleolar RNA.

Input: Consider Input: This study aimed to evaluate the long-term outcomes and the soft-tissue response to osseous genioplasty in patients with chin retrusion caused by early life facial burn injury.', 'Twenty-two consecutive patients with retrusive chin as a result of severe childhood facial burn were included in this study. Cephalometric analysis and photographs were used to assess the patients for eligibility of a surgical correction. Horizontal hard-tissue advancement and soft-tissue responses were measured as the primary outcomes at the early and late postoperative follow-up visits.', 'A total of 22 patients fulfilled the study requirements. Average preoperative distance between the pogonion, as the most anterior point of the anterior mandibular contour, and a perpendicular line connecting the nasion and the supramental point of the mandible was 0.82 1.1 mm, which increased significantly to 7.8 0.8 mm after genioplasty (p < 0.0001). Soft tissue was repositioned on average 6.1 0.4 mm anteriorly on average, which is in comparison with the amount of chin skeleton advancement, and a response ratio of 0.8:1 was calculated at late follow-up.

Input: Consider Input: Receptor down-regulation by the multivesicular body (MVB) pathway is critical for many cellular signaling events. MVB generation is mediated by the highly conserved ESCRT (0, I, II, and III) protein complexes. Chmp1 is an ESCRT-III component and a putative tumor suppressor in humans. However, published data on Chmp1 activity are conflicting and its role during tissue development is not well defined.', 'We investigated the function of Drosophila Chmp1 and found that it is an essential gene. In the wing, loss of Chmp1 activity causes a cell fate change from intervein to vein, and interactions between Chmp1 and Drosophila Epidermal Growth Factor Receptor (DER) regulators suggest that Chmp1 negatively regulates DER signaling. Chmp1 knockdown also decreases Blistered expression, which is repressed by DER signaling. We find that Chmp1 protein localizes to the late endosome in Drosophila embryos, which is consistent with its effects on DER signaling resulting from its function in the ESCRT-III complex.
