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.

[EX Q]: 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).

[EX Q]: Inhalation of nitric oxide (NO) and inhibition of phosphodiesterase type 5 (PDE5) selectively dilate the pulmonary circulation in patients with acute lung injury (ALI) associated with pulmonary hypertension. PDE5 inhibitors administered at doses that decrease pulmonary artery pressures have been shown to worsen arterial oxygenation. We investigated the efficacy of doses of PDE5 inhibitors that do not reduce pulmonary artery pressure alone (subthreshold doses) to improve the response to inhaled NO in an animal model of ALI.', 'Adult Sprague-Dawley rats were pre-treated with 0.5 mg/kg Escherichia coli 0111:B4 endotoxin and 16 to 18 h later, their lungs were isolated perfused and ventilated. The thromboxane mimetic U46619 was used to induce pulmonary hypertension. After the determination of subthreshold doses of two different PDE5 inhibitors, either 50 microg zaprinast or 10 ng sildenafil was added to the perfusate and the decrease of pulmonary artery pressure measured in the presence and absence of inhaled NO.', 'In the presence of 4 or 10 ppm NO, zaprinast (-1.6 +/- 0.4 and -2.9 +/- 0.6 mmHg, respectively) and sildenafil (-1.9 +/- 0.4 and -2.4 + 0.3 mmHg, respectively) improved responsiveness to inhaled NO compared to lungs from rats treated with LPS only (0.7 +/- 0.1 and -1.0 +/- 0.1 mmHg, respectively; P<0.05). Neither zaprinast nor sildenafil prolonged the pulmonary vasodilatory response to inhaled NO.

[EX Q]: This study investigated the association between serum gamma-glutamyltransferase (GGT) level and subclinical atherosclerosis in patients with type 2 diabetes.', 'This cross-sectional study involved 1024 patients with type 2 diabetes mellitus. Measurement of brachial-ankle pulse wave velocity (baPWV; as a marker of arterial stiffness) and an ultrasound assessment of carotid atherosclerosis were performed. Subclinical atherosclerosis was defined by the presence of a high baPWV (≥1720\xa0cm/s), carotid atherosclerosis (intima-media thickness\xa0>0.8\xa0mm or the presence of plaques), and carotid stenosis (≥50\xa0% of luminal narrowing). The subjects were stratified into quartiles according to GGT level, and the relationship between GGT level and subclinical atherosclerosis was analysed.', 'Serum GGT levels were closely associated with obesity, atherogenic dyslipidemia, and metabolic syndrome. However, serum GGT levels did not show a linear association with baPWV, carotid intima-media thickness, or plaque grade. The prevalence of high baPWV, carotid atherosclerosis, and carotid stenosis did not differ between the quartiles in men and women. Multivariate logistic regression analyses revealed no association between GGT level and high baPWV, carotid atherosclerosis, and carotid stenosis, either as continuous variables or quartiles.
