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: The aim of this study was to evaluate and compare microwave disinfection with chemical disinfection of dental gypsum casts.', 'A total of 120 casts were prepared from a silicone mold using Type III dental stone. Of the 120 casts, 60 casts were contaminated with 1 ml suspension of Staphylococcus aureus and 60 casts were contaminated with 1 ml suspension of Pseudomonas aeruginosa. Then, the casts were disinfected with microwave irradiation and chemical disinfection using the microwave oven and 0.5% sodium hypochlorite. Bacteriologic procedures were performed; the cfu/ml for each cast was calculated as a weighted mean. The results were analyzed using Kruskal-Wallis test and Mann-Whitney test.', 'The untreated casts showed Brain heart infusion broth counts of 106 log cfu/ml compared to irradiated and chemically disinfected casts, in which 105 log reduction of cfu/ml was seen. These results satisfied the requirements of current infection control guidelines for the dental laboratory. The results obtained for chemical disinfection were in equivalence with microwave disinfection.

Input: Consider Input: Human inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis), is associated with leukocyte accumulation in the inflamed intestinal tissue. Recent studies strongly suggest a role of beta1 integrin receptors in regulating tissue damage and disease symptoms related to inflammatory bowel disease. The aim of this study was to investigate the role of the collagen-binding alpha2beta1 integrin (CD49b/CD29) in dextran sodium sulfate-induced colitis in mice.", 'Colitis was induced in mice through oral administration of 2% dextran sodium sulfate in drinking water. Rectal administration of anti-alpha2-monoclonal antibody (mAb) in 1 group was compared with oral treatment with betamethasone in another group and rectal administration of a control antibody in a third group. Clinical and histological signs of colitis, neutrophil infiltration into the colon mucosa, and gene expression of metalloproteinases were assessed.', 'Rectal administration of anti-alpha2-mAb was found to significantly reduce weight loss from 13.5% +/- 6.5% to 2.2% +/- 0.2% (P = 0.013 versus control mAb) and mucosal neutrophil infiltration from 47.2 +/- 10.0 to 6.6 +/- 8.0 neutrophils per counted area (P < 0.05 versus control mAb). Metalloproteinase gene expression was suppressed through anti-alpha2-mAb treatment. The protective effect against colitis seen after anti-alpha2beta1 integrin treatment was found to be favorable to the effect seen after high-dose oral betamethasone.

Input: Consider Input: Transcription factors are critical in regulating lens development. The AP-2 family of transcription factors functions in differentiation, cell growth and apoptosis, and in lens and eye development. AP-2, in particular, is important in early lens development, and when conditionally deleted at the placode stage defective separation of the lens vesicle from the surface ectoderm results. AP-2's role during later stages of lens development is unknown. To address this, the MLR10-Cre transgene was used to delete AP-2 from the lens epithelium beginning at embryonic day (E) 10.5.", 'The loss of AP-2 after lens vesicle separation resulted in morphological defects beginning at E18.5. By P4, a small highly vacuolated lens with a multilayered epithelium was evident in the MLR10-AP-2 mutants. Epithelial cells appeared elongated and expressed fiber cell specific B1 and -crystallins. Epithelial cell polarity and lens cell adhesion was disrupted and accompanied by the misexpression of ZO-1, N-Cadherin, and -catenin. Cell death was observed in the mutant lens epithelium between postnatal day (P) 14 and P30, and correlated with altered arrangements of cells within the epithelium.
