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.

Example Input: Compared with standard donors, kidneys recovered from donors after cardiac death (DCD) exhibit higher rates of delayed graft function (DGF), and DCD livers demonstrate higher rates of biliary ischemia, graft loss, and worse patient survival. Current practice limits the use of these organs based on time from donor extubation to asystole, but data to support this is incomplete. We hypothesized that donor postextubation parameters, including duration and severity of hemodynamic instability or hypoxia might be a better predictor of subsequent graft function.', 'We performed a retrospective examination of the New England Organ Bank DCD database, concentrating on donor factors including vital signs after withdrawal of support.', 'Prolonged, severe hypotension in the postextubation period was a better predictor of subsequent organ function that time from extubation to asystole. For DCD kidneys, this manifested as a trend toward increased DGF. For DCD livers, this manifested as increased rates of poor outcomes. Maximizing the predictive value of this test in the liver cohort suggested that greater than 15 min between the time when the donor systolic blood pressure drops below 50 mm Hg and flush correlates with increased rates of diffuse biliary ischemia, graft loss, or death. Donor age also correlated with worse outcome.

Example Input: 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.

Example Input: Glucose-transporter-1 (Glut-1) may be a useful marker for differentiating B3 thymomas and thymic carcinomas. Since the literature is limited, we undertook a study to evaluate its diagnostic value in a series of thymic epithelial tumors.', 'Glut-1 expression was studied by the group of pathologists linked to the French national oncological network RYTHMIC. Immunostaining was performed on a whole section of one paraffin block in a series of 92 successive surgical specimens. Patterns (focal, zonal, diffuse) and intensity of Glut-1 expression were assessed and compared with WHO histological subtypes.', 'Expression was mainly restricted to epithelial cells. Immature T-lymphocytes were negative. A diffuse, moderate or strong staining was observed in most thymic carcinomas (15/16). In B3 thymomas (10/11) and in B3 thymomas borderline to thymic carcinomas (5/6), a moderate to strong zonal staining was observed at distance from vessels and fibrous septa. This pattern sometimes created the aspect of an anastomosing network in large cellular lobules. In B1 thymomas, immunostaining highlighted foci of medullary differentiation (7/8). B2 thymomas (n=25) were heterogeneous, with a spectrum of patterns ranging between those of B1 and B3 thymomas. Type A thymomas (n=5) mostly presented a weak positivity but one aggressive case showed zonal moderate/strong positivity. Most AB thymomas (15/17) showed weak to moderate immunostaining in spindle cell areas. In micronodular thymomas (n=3), epithelial cells and B-lymphocytes were weakly positive while follicular dendritic cells were strongly highlighted. One metaplastic thymoma displayed diffuse and moderate positivity.
