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: Hepatocellular carcinoma (HCC) is one of the most common solid tumors and ranks the third leading cause of cancer mortality worldwide. The purpose of this study was to examine the expression dynamics of GOLPH3 in HCC tissue samples, and explore the correlation between GOLPH3 expression and prognosis in patients with HCC.', 'The levels of Golgi phosphoprotein 3 (GOLPH3) mRNA and protein in liver cancer cell lines and fresh tissues were determined by qRT-PCR and Western blotting. Additionally, the protein expression of GOLPH3 was detected by immunohistochemistry.', 'High GOLPH3 expression was positively correlated with serum AFP level (P=0.015) and tumor recurrence or metastasis (P=0.010). In addition, liver cancer patients with high GOLPH3 expression had significantly poorer overall survival (HR, 1.87; 95% CI, 1.19-2.94; P=0.006) and poorer disease-free survival (HR, 1.90; 95% CI, 1.21-2.98; P=0.005) than those with low GOLPH3 expression. The cumulative 5-year survival rate was only 35.19% (95% CI, 26.18%-44.20%) in the high GOLPH3 expression group, whereas it was 55.93% (95% CI, 43.26%-68.60%) in the low GOLPH3 expression group. Furthermore, multivariate Cox regression analysis demonstrated that the expression of GOLPH3, tumor size and tumor multiplicity were independent prognostic predictors for HCC patients.

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: The aim of this study was to investigate the antiproliferative and cytotoxic effects of a newly synthesized molecule named paracetamol acetohydroxamic acid (PaCaHa) on human neoplastic cell lines.', 'A549, CRL 2923, HeLa, and ARPE were treated with various concentrations of PaCaHa and DMSO (vehicle control). The cytotoxic/cytostatic effects of PaCaHa were determined after a 24-h incubation period and compared to the DMSO control. The cytotoxic and antiproliferative effects were determined by the trypan blue dye exclusion and MTT methods.', 'A higher susceptibility to PaCaHA was found in CRL 2923 and HeLa cells, while A549 and ARPE cells were less responsive to PaCaHa. The percent of cytotoxicity resulting from 400 µg/mL of PaCaHa were >90 for CRL-2923 and HeLa, 68 for A549, and 64 for ARPE cells. The cytotoxic difference between CRL-2923/HeLa and ARPE/A549 cells was significant (P < 0.05).
