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:
Transfusion of packed erythrocytes stored for a long duration is associated with increased pulmonary arterial pressure and vascular resistance. Prolonged storage decreases erythrocyte deformability, and older erythrocytes are rapidly removed from the circulation after transfusion. The authors studied whether treating stored packed ovine erythrocytes with NO before transfusion could prevent pulmonary vasoconstriction, enhance erythrocyte deformability, and prolong erythrocyte survival after transfusion.', 'Ovine leukoreduced packed erythrocytes were treated before transfusion with either NO gas or a short-lived NO donor. Sheep were transfused with autologous packed erythrocytes, which were stored at 4°C for either 2 ("fresh blood") or 40 days ("stored blood"). Pulmonary and systemic hemodynamic parameters were monitored before, during, and after transfusion. Transfused erythrocytes were labeled with biotin to measure their circulating lifespan. Erythrocyte deformability was assessed before and after NO treatment using a microfluidic device.', 'NO treatment improved the deformability of stored erythrocytes and increased the number of stored erythrocytes circulating at 1 and 24\u2009h after transfusion. NO treatment prevented transfusion-associated pulmonary hypertension (mean pulmonary arterial pressure at 30\u2009min of 21\u2009±\u20091 vs. 15\u2009±\u20091 mmHg in control and NO-treated packed erythrocytes, P < 0.0001). Washing stored packed erythrocytes before transfusion did not prevent pulmonary hypertension.

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:
The Notch signaling pathway has been shown to play a role in bone marrow-derived stromal cell differentiation, however, the precise outcome of Notch activation remains controversial. The aim of this study was to evaluate the effect of Notch signaling in primary human bone marrow-derived stromal cells (hBMSCs).', 'hBMSCs were transduced to >90% with lentiviral vectors containing either human notch1 intracellular domain (NICD), jagged1, or dominant negative mastermind1. Cells were exposed to adipogenic and osteogenic differentiation stimuli and differentiation was quantified by oil red or alizarin red staining, alkaline phosphatase liver/bone/kidney (ALPL) activity and expression of adipogenic or osteogenic marker genes.', 'NICD and jagged1 transgene-expressing hBMSCs demonstrated enhanced mineralization, nodule formation, and ALPL activity in osteogenic differentiation media. These findings correlated with increased gene expression of bone morphogenetic protein 2 and ALPL. In contrast, NICD or jagged1 transgene expression strongly inhibited adipocyte formation and reduced peroxisome proliferator-activated receptor-gamma, fatty acid binding protein 4, and adiponectin precursor gene expression. Co-overexpression of dominant negative mastermind1 and NICD or jagged1 led to a partial rescue of the differentiation phenotypes. In addition, high endogenous jagged1 expression levels were observed in hBMSCs samples with strong ALPL activity compared to a group of samples with low ALPL activity.
