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: Lung inflation causes cardiovascular suppression via an increase in intrathoracic pressure and neural mechanisms. To examine the mechanisms involved, we mea-sured the heart rate (HR) and arterial blood pressure (AP) responses to lung inflation before and after spraying the bronchi with lidocaine to suppress airway reflex. Thirty women participated in the study. One group (n = 20, Group BT) had their tracheas intubated by using double-lumen tubes. The other group (n = 10, Group TT) received an ordinary endotracheal tube. They were all studied under general anesthesia by using nitrous oxide, isoflurane, and muscle relaxation after a thiopental induction. In each patient, airway pressure was increased for 3 s, and changes in HR and AP were measured. Lung inflation was repeated after 5 mL of 4% lidocaine had been sprayed into the main bronchi unilaterally in Group BT or bilaterally in Group TT. There were no significant differences in cardiovascular responses between left and right lung inflation with the pressure at 20 and 30 cm H(2)O. Both lungs inflated at 20 cm H(2)O caused an increase in HR with a significantly greater decrease in AP than with unilateral inflation. Anesthesia of the bronchi abolished the HR increase, but not the AP decrease. Lung inflation at 30 cm H(2)O caused significant decreases in HR and AP which were not affected with topical anesthesia. These results indicate that the cardiovascular responses elicited by lung inflation in anesthetized humans are predominantly the direct effect of the increase in intrathoracic pressure, although sympathetic afferent activity induced via stimulation of mechanoreceptors in the airways contributes.

Example Input: The objective of this study is to characterize differential proteomic expression among well-differentiation and poor-differentiation colorectal carcinoma tissues and normal mucous epithelium.', 'The study is based on quantitative 2-dimensional gel electrophoresis and analyzed by PDquest.', 'Excluding redundancies due to proteolysis and posttranslational modified isoforms of over 600 protein spots, 11 proteins were revealed as regulated with statistical variance being within the 95th confidence level and were identified by peptide mass fingerprinting in matrix assisted laser desorption/ionization time-of-flight mass spectrometry. Progression-associated proteins belong to the functional complexes of tumorigenesis, proliferation, differentiation, metabolism, and the regulation of major histocompatibility complex processing and other functions. Partial but significant overlap was revealed with previous proteomics and transcriptomics studies in CRC. Among various differentiation stage of CRC tissues, we identified calreticulin precursor, MHC class I antigen (human leukocyte antigen A ), glutathione S-transferase pi1, keratin 8, heat shock protein 27, tubulin beta chain, triosephosphate, fatty acid-binding protein, hemoglobin (deoxy) mutant with val b 1 replaced by met (HBB), and zinc finger protein 312 (FEZF2).

Example Input: Previous studies have proved the feasibility of performing a pancreaticoduodenectomy (Whipple operation) in patients with portal vein-superior mesenteric vein and hepatic artery invasion. We report our institutional experience with the use of a variety of vascular reconstructive methods during pancreatic resections for adenocarcinoma.', 'A retrospective review was performed identifying all patients undergoing a Whipple operation or total pancreatectomy procedure from January 2003 to December 2013. All venous (portal vein-superior mesenteric vein) and arterial (superior mesenteric artery-hepatic artery) reconstructions were extracted and reviewed to determine survival and perioperative complications.', 'During the 10-year study period, 270 Whipple and total pancreatectomy procedures were performed, of which 183 were for adenocarcinoma of the pancreas. Of the 183 operations, a total of 60 (32.8%) vascular reconstructions were found, 49 venous and 11 arterial. Venous reconstruction included 37 (61.7%) primary repairs, four (6.7%) reconstructions with CryoVein (CryoLife, Inc, Kennesaw, Ga), three (5.0%) repairs with autologous vein patch, three (5.0%) autologous saphenous reconstructions, and two (3.33%) portacaval shunts. In addition, there were 11 (18.3%) arterial reconstructions (seven hepatic artery and four superior mesenteric artery). The 1-year survival for all reconstructions was 71.1%, which is equivalent to T3 lesions that did not receive vascular reconstruction (70.11%), with a median survival time of 575.28 days and 12 patients still alive. Survival time was comparable with each type of venous reconstruction, averaging 528 days (11 of 49 patients still alive). There was a total thrombosis rate of seven of 60 (11.6%), all of which were portal vein thrombosis: three in the primary repair group and four delayed thromboses seen in primary repair, CryoVein repair, and vein patch repair. There was no thrombosis in any patients after arterial reconstruction.
