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:
HAGE protein is a known immunogenic cancer-specific antigen.', 'The biological, prognostic and predictive values of HAGE expression was studied using immunohistochemistry in three cohorts of patients with BC (n=2147): early primary (EP-BC; n=1676); primary oestrogen receptor-negative (PER-BC; n=275) treated with adjuvant anthracycline-combination therapies (Adjuvant-ACT); and primary locally advanced disease (PLA-BC) who received neo-adjuvant anthracycline-combination therapies (Neo-adjuvant-ACT; n=196). The relationship between HAGE expression and the tumour-infiltrating lymphocytes (TILs) in matched prechemotherapy and postchemotherapy samples were investigated.', 'Eight percent of patients with EP-BC exhibited high HAGE expression (HAGE+) and was associated with aggressive clinico-pathological features (Ps<0.01). Furthermore, HAGE+expression was associated with poor prognosis in both univariate and multivariate analysis (Ps<0.001). Patients with HAGE+did not benefit from hormonal therapy in high-risk ER-positive disease. HAGE+and TILs were found to be independent predictors for pathological complete response to neoadjuvant-ACT; P<0.001. A statistically significant loss of HAGE expression following neoadjuvant-ACT was found (P=0.000001), and progression-free survival was worse in those patients who had HAGE+residual disease (P=0.0003).

question:
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.

question:
To investigate changes in autoreactive T-cell responses against PMP-22 and P2 antigen as well as a T-cell memory repertoire in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) induced by repeated intravenous immunoglobulin (IVIg) treatment.', 'In an observational trial, we prepared cryopreserved human peripheral blood monocytes from blood from 34 patients with CIDP (18 treatment naive and 16 maintenance IVIg treatment) and from 14 healthy controls (non-immune neuropathy and healthy control). Treatment response was defined by clinical evaluation. The autoantigen-specific T-cell response was analysed by enzyme linked immunosorbent spot (ELISPOT) assay before IVIg start (baseline) and at follow-up. The T-cell memory subsets were analysed by using flow cytometric analysis.', 'Myelin-derived P2-specific and PMP-22-specific IFN- producers were increased in IVIg responders compared with non-responders before treatment, which decreased by repeated IVIg infusion cycles. Treatment responders but not non-responders showed higher frequencies of CD4 T effector memory (TEM) and T central memory frequencies at baseline compared with maintenance IVIg treatment patients and controls. In addition, IVIg treatment was associated with a significant reduction in CD8 TEM at follow-up.
