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: Severity of pancreatitis seems to be aggravated by impairment of vascular perfusion of the gland. Early mortality occurs within the first few days from the acute consequences of pancreatic injury with subsequent inflammatory response. Because vasoactive substances, including endothelin, seem to contribute to early mortality in acute pancreatitis, we tested the hypothesis that the inhibition of endothelin action could alter the outcome after severe experimental pancreatitis.', 'In two groups of rats, pancreatitis was induced by intraductal infusion into the pancreatic duct of 1 microL/g body weight (b.w.) of either a 4% or a 5% sodium taurocholate solution. The mixed endothelin A and endothelin B receptor antagonist bosentan (20 mg/kg b.w.) or vehicle was injected intravenously in 12-h intervals for 3 d starting 1 h after induction of bile acid pancreatitis. This dose of bosentan is known to completely inhibit the effect of exogenous endothelin. The survival rate was monitored for 7 d. Thereafter, the surviving rats were sacrificed and the pancreas was prepared for histological and biochemical evaluation.', 'Irrespective of the treatment protocol (bosentan versus saline), survival was not different in animals challenged with either 4% or 5% sodium taurocholate. The corresponding survival rates were 62% with bosentan and 77% without bosentan in the 4% sodium taurocholate group. In the 5% sodium taurocholate group, the survival rates were 20% with and 27% without bosentan. Morphological and biochemical alterations were identical in control as well as in endothelin-antagonist-treated rats.

Input: Consider Input: It remains controversial whether the cure of H. pylori infection improves NUD symptoms.', 'To conduct a double-blind placebo-controlled single centre study with concealed allocation to investigate this question.', 'Ninety NUD patients with H. pylori infection were randomly assigned to either the treatment group (50 patients) or placebo group (40 patients). The treatment group received omeprazole, amoxycillin, clarithromycin and the placebo group received omeprazole and placebos for 7 days. Symptoms were assessed every week for up to 12 weeks after completion of medication by a symptom questionnaire. Alteration of histological parameters for gastritis was also evaluated.', 'The infection was cured in 41 out of 48 patients in the treatment group and none in the placebo group. There was no significant difference in the mean symptom scores at any assessment point up to 12 weeks between the treatment and placebo groups. Regarding histological parameters, activity and inflammation, not atrophy or intestinal metaplasia, were significantly improved in the treatment group.

Input: Consider Input: Chronic transfusion therapy causes a progressive iron overload that damages many organs including the heart. Recent evidence suggests that L-type calcium channels play an important role in iron uptake by cardiomyocytes under conditions of iron overload. Given that beta-adrenergic stimulation significantly enhances L-type calcium current, we hypothesised that beta-adrenergic blocking drugs could reduce the deleterious effects of iron overload on the heart.', 'Iron overload was generated by intraperitoneal injections of iron dextran (1g/kg) administered once a week for 8 weeks in male C57bl/6 mice, while propranolol was administered in drinking water at the dose of 40 mg/kg/day. Cardiac function and ventricular remodelling were evaluated by echocardiography and histological methods.', 'As compared to placebo, iron injection caused cardiac iron deposition. Surprisingly, despite iron overload, myocardial function and ventricular geometry in the iron-treated mice resulted unchanged as compared to those in the placebo-treated mice. Administration of propranolol increased cardiac performance in iron-overloaded mice. Specifically, as compared to the values in the iron-overloaded group, in iron-overloaded animals treated with propranolol left ventricular fractional shortening increased (from 31.6% to 44.2%, P =0.01) whereas left ventricular end-diastolic diameter decreased (from 4.1 ± 0.1 mm to 3.5 ± 0.1 mm, P =0.03). Propranolol did not alter cardiac systolic function or left ventricular sizes in the placebo group.
