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.

[Q]: We aimed to better discriminate metastasized (lymphogen/occult/both combined) from non-metastasized seminoma based on post-transcriptional changes examined in the peripheral blood.', 'Total RNAs including small RNAs were isolated from the peripheral blood of patients suffering from metastasized testicular tumours (lymphogen, n = 5, clinical stage IIb/c; occult, n = 5, clinical stage I) and non-metastasized patients (n = 5, clinical stage I). Small RNA next generation sequencing (SOLID, Life Technologies) was employed to examine post-transcriptional changes. We searched for small RNAs showing at least 50 reads and a significant\u2009 ≥ 2-fold difference using peripheral blood small RNAs of non-metastasized tumours as the reference group. Candidate small RNAs were examined in univariate logistic regression analysis and combinations of two small RNAs were further examined using support vector machines.', 'On average 1.3 x 10(7), 1.2 x 10(7) and 1.2 x 10(7) small RNA reads were detectable in non-metastasized, lymphogen and occult metastasized seminoma, respectively of which 73-76% remained after trimming. From these between 80-82% represented annotated reads and 7.2-7.8% (1.6-1.7 x 10(4)) were annotated small RNA tags. Of them 137 small RNAs showed > 50 reads and a ≥ two-fold difference to the reference. In univariate analysis we detected 33-35 different small RNAs which significantly discriminated lymphogen/occult/combined metastasized from non-metastasized seminoma and among these different comparisons it were the same small RNAs in 44-79%. Many combinations of two of these small RNAs completely discriminated metastasized from non-metastasized seminoma irrespective of the metastasis subtype.

[Q]: The hepatitis B virus X protein (HBx) plays critical roles in cell survival via modulation of signaling pathways. In our previous studies, we reported that HBx inhibited the growth of CCL13-HBx-stable cells (Chang-HBx cells) in vitro and tumor formation in vivo in CCL13-HBx-cell-injected nude mice; however, this inhibition mechanism is unclear.', 'To investigate the role of HBx in Wnt-3/beta-catenin signaling pathways, we focused on the key molecules GSK-3beta and beta-catenin, and analyzed by Western blotting and immunofluorescence staining.', 'Results indicated that following HBx induction, GSK-3beta activity was up-regulated, the expression and accumulation of beta-catenin in the nucleus were decreased, and cell proliferation was suppressed. Inhibition of GSK-3beta activity by pharmacological inhibitors rescued the expression and accumulation of beta-catenin in the nucleus and facilitated cell proliferation and growth following HBx induction. The localization of beta-catenin, which is involved in cell proliferation, and mediated by GSK-3beta activation was also demonstrated.

[Q]: Limited data exist on the prognosis of preoperative Helicobacter pylori (H. pylori) infection in gastric adenocarcinoma (GAC).', 'Patients who underwent curative-intent resection for GAC from 2000 to 2012 at seven academic institutions comprising the United States Gastric Cancer Collaborative were included in the study. The primary end points of the study were overall survival (OS), recurrence-free survival (RFS), and disease-specific survival (DSS).', 'Of 559 patients, 104 (18.6\xa0%) who tested positive for H. pylori were younger (62.1 vs 65.1\xa0years; p\xa0=\xa00.041), had a higher frequency of distal tumors (82.7 vs 71.9\xa0%; p\xa0=\xa00.033), and had higher rates of adjuvant radiation therapy (47.0 vs 34.9\xa0%; p\xa0=\xa00.032). There were no differences in American Society of Anesthesiology (ASA) class, margin status, grade, perineural invasion, lymphovascular invasion, nodal metastases, or tumor-node-metastasis (TNM) stage. H. pylori positivity was associated with longer OS (84.3 vs 44.2\xa0months; p\xa0=\xa00.008) for all patients. This relationship with OS persisted in the multivariable analysis (HR 0.54; 95\xa0% CI 0.30-0.99; p\xa0=\xa00.046). H. pylori was not associated with RFS or DSS in all patients. In the stage 3 patients, H. pylori was associated with longer OS (44.5 vs 24.7\xa0months; p\xa0=\xa00.018), a trend of longer RFS (31.4 vs 21.6\xa0months; p\xa0=\xa00.232), and longer DSS (44.8 vs 27.2\xa0months; p\xa0=\xa00.034).
