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.

The etiology and pathogenesis of inflammatory bowel disease remain unknown. However, neutrophil infiltration into the inflammatory lesion is an important process in inflammatory bowel disease. In this study, we used rat trinitrobenzene sulfonic acid (TNBS) ileitis as a Crohn's disease model, and investigated the effects of oral IS-741 (which inhibits the expression of Mac-1, a cell adhesion molecule) on leukocyte-endothelial interactions.", 'Rat ileitis was induced by the intraluminal injection of a TNBS solution (160 mg/kg in 50% ethanol) at a site 10 cm proximal to the ileocecal valve. The rats then received oral IS-741 (50 mg/kg) or saline for 7 days. On the day 8 after the initial administration of IS-741 or saline, we determined the visible damage score, and assessed myeloperoxidase (MPO) activity. Concentrations of cytokines in the ileum, such as interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha) were assayed by enzyme-linked immunosorbent assay (ELISA). We also investigated the infiltration of polymorphonuclear cells and Mac-1 positive cells by histological examinations.', 'The administration of IS-741 resulted in a significant reduction of the visible damage score, myeloperoxidase (MPO) activity, and mucosal IL-8 levels in the ileum as compared with the saline administration. IS-741 also dramatically reduced the infiltration of polymorphonuclear cells and Mac-1 positive cells into the inflamed lesions.

Transient tachypnea of the newborn (TTN) is a benign disorder with a variable clinical course that often leads to hospitalization. The aim of this study was to assess and validate the relationship between the serum cystatin C level and symptom duration in infants with TTN.', 'Forty newborns presenting with TTN and who had undergone serum cystatin C (Cys C) tests on the first day of admission to the Kyung Hee University Hospital (Seoul, Korea) from 2009 to 2013 were included. The serum Cys C level, creatinine (Cr) level, estimated glomerular filtration rate (eGFR), and tachypnea duration were correlated retrospectively.', 'The median gestation period was 37.83.8 weeks and the mean birth weight was 3.20.4kg. Tachypnea duration was 3.32.0 days. Serum Cys C and Cr levels were 1.70.2mg/L and 0.81.2mg/dL, respectively. Tachypnea duration was significantly positively correlated with the serum levels of Cys C and significantly negatively correlated with Cys C-based eGFR (p=0.016), but was not significantly correlated with the serum Cr level or Cr-based eGFR. When tachypnea duration was compared between infants with Cys C level <1.6mg/L (n=15; Group A) and infants with Cys C level1.6mg/L (n=25; Group B), the symptom duration was significantly shorter in Group A infants (p=0.011).

We investigated the miR-196a2T>C rs11614913 variant in the initiation and progression of hepatocellular carcinoma (HCC).', 'A case-control research model was conducted and the genotypes of 109 HCC patients and 105 healthy controls were identified by direct sequencing. The correlation between the rs11614913 genotypes and the susceptibility to HCC was evaluated using an unconditional logistic regression model.', 'We found that 20/109 (18.3%) patients were TT homozygote, whereas 64/109 (58.8%) patients had the CT genotype, and 25/109 (22.9%) patients had the CC genotype. In control samples, the frequency of the TT homozygote was 33.3%, that of CT was 49.5%, and that of CC was 17.1%. After adjusting for age and gender by logistic regression analysis, we found significant differences in susceptibility to HCC by genotype (TT vs. CT+CC: OR=2.52, 95%CI=1.18-4.19; p<0.05). The CT and CC genotypes were more common in HCC patients compared to controls. Moreover, the CT+CC genotypes were associated with a poor HCC prognosis.
