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 purpose of this study was to compare the arterial response following implantation of a stainless-steel, balloon-expandable, tubular slotted stent with that of a novel computer-designed, multi-cellular stent in normal porcine coronary arteries.', 'Intracoronary stent placement has evolved into the primary strategy for percutaneous revascularization of symptomatic coronary arterial lesions. Presently there is intense interest in developing new stent designs to improve stent delivery and biocompatability.', 'Computer-assisted design was utilized to develop a balloon-expandable stent with symmetric expansion properties, uniform arterial wall coverage, longitudinal flexibility and radial strength. Quantitative coronary angiography and histological assessment of the stented arteries was used to evaluate the acute and chronic vascular responses to a stainless-steel, balloon-expandable, tubular slotted stent as compared to the computer-designed BX stent in the normolipemic swine.', 'Forty stents (24 BX, 16 tubular slotted) were implanted in 19 miniature swine at a mean inflation pressure of 9 atm using identical delivery systems. Eight of the BX and none of the tubular slotted stents were post-dilated with a non-compliant balloon at 12-14 atm. The mean stent-to-artery ratio was similar for the BX (1.03 +/- 0.06) and tubular slotted (1.04 +/- 0.11; p = 0.59) designs. Protrusion or asymmetric radial flaring of a strut at the stent margin was present in 1 of 23 BX stents (4.3%) and 10 of 15 tubular slotted stents (66.7%; p < 0.0001). The mean arterial injury score was significantly less for the BX stent (0.2 +/- 0.2) as compared with the tubular slotted stents (0.4 +/- 0.4; p = 0.025). At 3 days, thrombus area was similar for the BX and tubular slotted designs (0.42 +/- 0.16 mm2 versus 0.44 +/- 0.18 mm2, respectively; p = 0.88). The mean neointimal area was significantly less for the BX at 2 months (1.09 +/- 0.25 mm2 versus 2.93 +/- 2.26 mm2 in the tubular slotted stent) and at 6 months (1.10 +/- 0.26 mm2 versus 2.07 +/- 0.65 mm2 in the tubular slotted stent; p = 0.01), resulting in approximately 50% less in-stent stenosis.

Input: Consider Input: To investigate the effects of quercetin, an herbal flavonoid, on LPS-induced delay in spontaneous apoptosis, adhesion molecules (CD62L, CD11b/CD18) expression of neutrophils, and superoxide (O(2)(-)) generation by LPS-primed fMLP-induced human neutrophils.', 'Neutrophils were incubated in the presence or absence of lipopolysaccharide (LPS) at a final concentration of 1 microg/ml for 24 hours. Some wells with neutrophils were pre-treated with quecetin at the final concentration ranging from 0-100 microM for 30 min and then 1 microg/ml LPS was added into the cultures for 24 hours. The apoptosis of neutrophils was evaluated by flowcytometry analysis of propidum iodide (PI)-staining of the nuclei and annexin V staining of phosphatidylserine (PS) in the cell membrane. Agarose gel electrophoresis of low molecular weight DNA was performed to analyze DNA fragmentation. The effects of quercetin on adhesion molecules were detected by using flowcytometry analysis. The generation of O(2) (-) by LPS-primed fMLP-induced neutrophils was determined by reduced cytochrome c assay.', 'LPS markedly inhibited the spontaneous apoptosis of neutrophils, but the inhibitory effect was abrogated after the pre-treatment of neutrophils with quercetin (approximately 40 microM) for 30 min. Quercetin (40 microM) also prevented LPS-induced down-regulation of CD62L expression, up-regulation of CD11b/CD18 expression, and O(2) (-) generation by fMLP-induced neutrophils.

Input: Consider Input: The COMFORT behaviour scale (COMFORT-B scale) is widely used in paediatric intensive care units to assess young children's pain and distress. It is also used to assess the impact of treatment interventions, but little is known on the scale's sensitivity to detect changes between before and after measurements following an intervention. This study explored the sensitivity to change of the COMFORT-B scale.", 'COMFORT-B scores, originally and prospectively collected as part of standard care, were retrieved from the digital patient data management system. We analysed scores obtained in 747 paired observations, i.e., before and after a pharmacological intervention in 180 paediatric intensive care patients between September 2009 and September 2010.', 'The mean scores before and after an intervention were 20.0 [standard deviation (SD) 3.7] and 14.1 (SD 4.7), respectively. Multilevel regression analysis showed a 6-point mean decline after an intervention (p<0.0001). The magnitude of this decline was not statistically significantly related to number and type of interventions or time between assessments. In almost three-quarters of cases (74%), the COMFORT-B score dropped to below 17 after a pharmacological intervention, indicating good responsiveness.
