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: Surgery has been the gold standard in the treatment of adult pyloric stenosis (APS). The introduction of proton pump inhibitors (PPIs) in 1989 revolutionised the treatment of peptic ulcer disease and its complications.', 'We carried out a prospective study to evaluate the effectiveness of PPIs as an alternative to surgery for treatment of APS. Six consecutive patients admitted with a diagnosis of adult peptic pyloric stenosis between November 1999 and August 2002 were studied. The diagnosis was confirmed with endoscopy. All patients were commenced on a twice-daily dose of intravenous PPI. This was changed to oral treatment after 2 days. Main outcome measures evaluated were resolution of symptoms on PPIs and failure of medical therapy.', 'There were five females and one male. Median age at diagnosis was 72 years (range, 30-90 years). Median duration of symptoms was 2 weeks (range, 1-5 weeks). Of the patients, five had a history of peptic ulcer disease. Complete resolution was achieved in 5 patients (83%). Median duration for resolution of symptoms was 9 days (range, 5-14 days). All patients were changed to oral PPIs after 2 days. One patient did not respond to oral therapy and required surgical intervention (pyloroplasty). Median follow-up was 26 months (range, 6-48 months). There was no recurrence of symptoms. All patients were discharged on low-dose PPI.

Input: Consider Input: Although the major limitation to exercise performance in patients with COPD is dynamic hyperinflation, little is known about its relation to daily physical activity.', 'To analyze the contribution of dynamic hyperinflation, exercise tolerance, and airway oxidative stress to physical activity in patients with COPD.', 'In a cross-sectional study, we included 110 patients with moderate to very severe COPD. Daily physical activity was measured using a triaxial accelerometer providing a mean of 1-minute movement epochs as vector magnitude units (VMU). Patients performed the 6-minute walk test, incremental exercise test with measurement of breathing pattern and operating lung volumes, and constant-work rate test at 75% of maximal work rate.', 'Using the GOLD stage and BODE index, we determined arterial blood gases, lung volumes, diffusing capacity, and biomarkers in exhaled breath condensate. Daily physical activity was lower in the 89 patients who developed dynamic hyperinflation than in the 21 who did not (n =161 [SD 70] vs. n = 288 [SD 85] VMU; P = 0.001). Physical activity was mainly related to distance walked in 6 minutes (r = 0.72; P = 0.001), Vo(2) (r = 0.63; P = 0.001), change in end-expiratory lung volume during exercise (r = -0.73; P = 0.001), endurance time (r = 0.61; P = 0.001), and 8-isoprostane in exhaled breath condensate (r = -0.67; P = 0.001). In a multivariate linear regression analysis using VMU as a dependent variable, dynamic hyperinflation, change in end-expiratory lung volume, and distance walked in 6 minutes were retained in the prediction model (r(2) = 0.84; P = 0.001).

Input: Consider Input: The heat shock protein (hsp27) correlates with thermotolerance and chemoresistance. Our main objective was to assess the response to radiotherapy both in vitro and in vivo in correlation with various concentrations of hsp27. The second objective was to evaluate the relation between hsp27 and glutathione-s-transferase pi (GST pi).', 'For the in vitro study, thermoresistant cell lines, expressing various amounts of hsp27, were used to assess the role of this protein in radioresistance. To verify the efficiency of hsp27 in these cells lines to confer resistance to cytotoxic agents, these cells were also treated with heat shock and cisplatin. Furthermore, the role of hsp27 expression was studied in vivo by immunochemistry in 98 patients with head and neck squamous cell carcinoma treated by radiotherapy. hsp27 was correlated with local control of the tumor and with clinical and biologic factors potentially able to affect the local control, including p53, ki-67, ploidy, and GST.', 'In vitro, high constitutive levels of expression of hsp27 did not significantly influence the survival curves of transfected cells exposed to radiation as compared to control cells although hsp27 overexpression was confirmed to increased the cellular resistance to heat and to cisplatinum. In vivo, we showed that overexpression of various amounts of hsp27 did not correlate with local control of the tumor. In vivo, hsp27 was only significantly associated with GST pi. Expression of GST pi was associated with poor local (p = 0.01) control and survival (p = 0.08) in a Cox model.
