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: The aim of this study is to determine the consequences of delayed presentation of anorectal malformations and emphasize the causes of delayed diagnosis of these malformations.', 'We retrospectively reviewed 54 neonatal patients with a diagnosis of anorectal malformations. Group 1 consisted of 35 patients diagnosed within the first 48h of life and Group 2 included 19 patients diagnosed after 48h of life.', 'Obstructive symptoms at the time of diagnosis, overall complications and the mean postoperative hospitalization period in Group 2 were markedly higher than that of Group 1. A comprehensive neonatal examination within the first 48h of life was performed in 32 (91.4%) patients in Group 1 and 5 (26.3%) of the patients in Group 2 (p<0.001).

Example Input: Arteriogenesis represents the maturation of preformed vascular connections in response to flow changes and shear stress. These collateral vessels can restore up to 60% of the native blood flow. Shear stress and vascular injury can induce the release of nucleotides from vascular smooth muscle cells and platelets that can serve as signaling ligands, suggesting they may be involved in mediating arteriogenesis. The P2Y2 nucleotide receptor (P2Y2R) has also been shown to mediate smooth muscle migration and arterial remodeling. Thus, we hypothesize that P2Y2R mediates arteriogenesis in response to ischemia.', 'Hind limb ischemia was induced by femoral artery ligation (FAL) in C57Bl/6NJ or P2Y2R negative mice (P2Y2(-/-)). Hind limb perfusion was measured with laser Doppler perfusion imaging and compared with the sham-operated contralateral limb immediately and at 3, 7, 14, 21, and 28 days after ligation. Collateral vessel size was measured by Microfil casting. Muscle specimens were harvested and analyzed with immunohistochemistry for Ki67, vascular cell adhesion molecule, macrophages, and muscle viability by hematoxylin and essoin stain.', 'Hind limb ischemia induced by FAL in C57Bl/6NJ mice resulted in significant ischemia as measured by laser Doppler perfusion imaging. There was rapid recovery to nearly normal levels of perfusion by 2 weeks. FAL in P2Y2(-/-) mice resulted in severe ischemia with greater tissue loss. Recovery of perfusion was impaired, achieving only 40% compared with wild-type mice by 28 days. Collateral vessels in the P2Y2(-/-) mice were underdeveloped, with reduced vascular cell proliferation and smaller vessel size. The collaterals were 65% the size of wild-type collateral vessels (P = .011). Angiogenesis at 28 days in the ischemic muscle, however, was greater in the P2Y2(-/-) mice (P < .001), possibly related to persistent ischemia leading and angiogenic drive. Early macrophage recruitment was reduced by nearly 70% in P2Y2(-/-) despite significantly more myocyte necrosis. However, inflammation was greater at 28 days in the P2Y2(-/-) mice.

Example Input: During allergic lung inflammation dendritic cells (DCs) direct the generation and function of effector T-helper type 2 cells. T-helper type 2 cells not only orchestrate the inflammatory processes in the tissue by inducing the accumulation and activation of proinflammatory cells but also induce IgE production by B cells. Thus, inhibitors of DC function should have therapeutic benefits in patients with allergies.', 'VAF347, a novel low molecular weight immunomodulator, is described and acts as an antiinflammatory compound by a dual mode of action.', 'VAF347 inhibited the function of human monocyte-derived DCs to induce T-cell proliferation and cytokine production. Mechanistically, this effect may be due to reduced expression of CD86, HLA-DR, and interleukin 6 by DCs. In addition, the compound inhibited IgE synthesis in an isotype-specific fashion by human B lymphocytes. In a mouse model of antigen-induced eosinophilic inflammation, VAF347 blocked lung eosinophilia, mucus hyperplasia, and serum IgE levels, representing the hallmarks of allergic lung inflammation. The biological effects in vivo are most likely mediated by the immunoregulatory role of VAF347 on DCs because allergic lung inflammation was also inhibited in B-cell-deficient mice.
