instruction:
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.
question:
To evaluate whether genotypes of interleukin (IL)-6 gene promoter positions -174 and -572 are associated with histologic chorioamnionitis and neonatal inflammatory disease in preterm infants.', 'DNA from very low birth weight or very preterm infants (n = 107) was genotyped for IL-6-174 and -572 polymorphisms (GG/GC/CC). The placentas were analyzed for histological inflammatory findings. Data on neonatal inflammatory diseases, including chronic lung disease (CLD), necrotizing enterocolitis (NEC), and septicemia, were collected using the definitions of the Vermont Oxford Network database.', 'In univariate analyses, the IL-6-174 GG genotype was associated with a higher incidence of histologic chorioamnionitis. In multivariate analyses, the -174 GG and -572 GC genotypes were correlated with histologic chorioamnionitis (P = .039 and .009, respectively). Gestational age was not associated with genotype polymorphisms. IL-6-174 genotypes were not associated with CLD and/or NEC, but the CC genotype was correlated with septicemia in both univariate and multivariate analyses (P = .027). IL-6-572 genotypes were not associated with neonatal inflammatory disease.

question:
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.

question:
Gastric carcinoids are slow growing neuroendocrine tumours arising from enterochromaffin-like (ECL) cells in the corpus of stomach. Although most of these tumours arise in the setting of gastric atrophy and hypergastrinemia, it is not understood what genetic background predisposes development of these ECL derived tumours. Moreover, diffuse microcarcinoids in the mucosa can lead to a field effect and limit successful endoscopic removal.', 'To define the genetic background that creates a permissive environment for gastric carcinoids using transgenic mouse lines.', 'The multiple endocrine neoplasia 1 gene locus (Men1) was deleted using Cre recombinase expressed from the Villin promoter (Villin-Cre) and was placed on a somatostatin null genetic background. These transgenic mice received omeprazole-laced chow for 6\u2005months. The direct effect of gastrin and the gastrin receptor antagonist YM022 on expression and phosphorylation of the cyclin inhibitor p27', 'The combination of conditional Men1 deletion in the absence of somatostatin led to the development of gastric carcinoids within 2\u2005years. Suppression of acid secretion by omeprazole accelerated the timeline of carcinoid development to 6\u2005months in the absence of significant parietal cell atrophy. Carcinoids were associated with hypergastrinemia, and correlated with increased Cckbr expression and nuclear export of p27
