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.

Q: To study the presence of citrullinated proteins in inflammatory conditions and in clinically non-affected tissues of controls.', 'Synovial biopsy specimens from 19 patients with rheumatoid arthritis and 10 healthy controls were investigated by immunohistochemistry. Additionally, muscle tissue from 5 patients with polymyositis and from 7 healthy controls, intestinal tissue from macroscopically affected and non-affected areas from 10 patients with inflammatory bowel disease (IBD) and tonsil tissues from 4 chronically inflamed tonsils were studied.', 'Citrullinated proteins were present in all synovial biopsy specimens from patients with rheumatoid arthritis, whereas only three of 10 healthy synovial biopsy specimens showed scarce amounts of citrullination. Citrullination was also present in all myositis-affected muscles, whereas it was absent in the muscle tissues of controls. All tonsil biopsy specimens studied were positive for citrulline. Even though more frequently detected in the macroscopically affected colonic areas, no marked difference was observed in the pattern or extent of citrullination between the macroscopically affected and non-affected intestinal IBD tissues.

Q: 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.

Q: Preexisting gastroesophageal reflux disease (GERD) and esophageal motility disorders may affect the outcome of laparoscopic adjustable gastric banding (AGB).', 'Prospective cohort study.', 'Tertiary referral center.', 'Between January 1, 1996, and December 31, 2002, AGB procedures were performed in 587 patients (mean body mass index, 46.7 [calculated as weight in kilograms divided by the square of height in meters]). The study population was composed of patients with preoperative GERD (assessed by a symptom-score questionnaire) and was divided into group 1 (those with preoperative GERD symptoms only) and group 2 (those with preoperative and postoperative GERD symptoms).', 'Laparoscopic AGB was performed according to the pars-flaccida technique.', 'All patients underwent preoperative and annual postoperative symptom scoring, endoscopy, esophageal barium swallow tests, esophageal manometry, and 24-hour pH monitoring.', 'Mean follow-up time was 33 months (range, 12-49 months). A total of 164 patients (27.9%) were diagnosed as having preoperative GERD symptoms. In 112 (68.3%) of these patients GERD symptoms vanished postoperatively (group 1), whereas 52 patients (31.7%) remained symptomatic after undergoing laparoscopic AGB implantation (group 2). Preoperatively, group 2 patients showed significantly poorer esophageal body motility compared with group 1 patients (20.8% vs 12.8% defective propagations; P = .007). In group 2 the mean symptom scores for dysphagia (0.4 vs 0.9) and regurgitation (0.6 vs 1.4) deteriorated significantly following laparoscopic AGB implantation, respectively. Eighteen patients (34.6%) in group 2 developed esophageal dilatation.
