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: 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).

Input: Consider Input: Splenectomy is a clinical risk factor for complicated thrombosis. We hypothesized that the loss of the mechanical filtering function of the spleen may enrich for thrombogenic phospholipids in the circulation, thereby affecting the vascular remodeling of thrombosis.', 'We investigated the effects of splenectomy both in chronic thromboembolic pulmonary hypertension (CTEPH), a human model disease for thrombus nonresolution, and in a mouse model of stagnant flow venous thrombosis mimicking deep vein thrombosis. Surgically excised thrombi from rare cases of CTEPH patients who had undergone previous splenectomy were enriched for anionic phospholipids like phosphatidylserine. Similar to human thrombi, phosphatidylserine accumulated in thrombi after splenectomy in the mouse model. A postsplenectomy state was associated with larger and more persistent thrombi. Higher counts of procoagulant platelet microparticles and increased leukocyte-platelet aggregates were observed in mice after splenectomy. Histological inspection revealed a decreased number of thrombus vessels. Phosphatidylserine-enriched phospholipids specifically inhibited endothelial proliferation and sprouting.

Input: Consider Input: Locally advanced colorectal cancer often requires extended resection to radically remove all tumor. This is the only chance for cure in these patients, but a higher complication rate would be expected. To evaluate the overall benefit for the patient, this study assesses morbidity and mortality as well as long-term survival of patients who underwent extended resection for a T3-T4 carcinoma.', 'Two hundred twenty patients with locally advanced adenocarcinoma of the colorectum were included. One hundred fifty presented with a T3 and 70 with a T4 tumor. Eighty-three patients underwent extended resection. In 38 patients extended en bloc resection was performed because of inflammatory adherence mimicking infiltration. Thirty-three patients who underwent extended resections were over 70 years of age. There were no significant differences between the groups that underwent extended or nonextended resections in age, sex, stage, or grading.', 'pT4 lesions were significantly more frequent in the extended resection group than in the nonextended resection group. Mean survival was 44 months after extended resections and 45 months after nonextended resections. In the extended resection group there was no significant difference in mean survival between pT3 and pT4 stage patients within 46 and 38 months, respectively. In patients who underwent nonextended resections, however, there was a significant difference in mean survival within 48 months for pT3 and 28 for pT4 patients (P < 0.05). Postoperative morbidity and mortality were comparable between the extended resection group and the non-extended resection group. The presence of residual tumor influenced prognosis of patients significantly; R0 resections fared significantly better than patients who underwent R1 or R2 resections (55 and 51 to 14/12 and 23/8 months) (P < 0.01). Nodal stage and International Union Against Cancer stage were also significant determinants of prognosis. After extended resections mean survival morbidity and 30-day mortality in patients more than 70 years was similar to those less than 70 years.
