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]: 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]: Systemic inflammatory response syndrome (SIRS) and sepsis are now frequently identified by observations of vital signs and detection of organ failure during triage in the emergency room. However, there is less focus on the effect on patient outcome with better observation and treatment at the ward level.', "This was a before-and-after intervention study in one emergency and community hospital within the Mid-Norway Sepsis Study catchment area. All patients with confirmed bloodstream infection have been prospectively registered continuously since 1994. Severity of sepsis, observation frequency of vital signs, treatment data, length of stay (LOS) in high dependency and intensive care units, and mortality were retrospectively registered from the patients' medical journals.", 'The post-intervention group (n=409) were observed better and had higher odds of surviving 30days (OR 2.7, 95% CI 1.6, 4.6), lower probability of developing severe organ failure (0.7, 95% CI 0.4, 0.9), and on average, 3.7days (95% CI 1.5, 5.9days) shorter LOS than the pre-intervention group (n=472).

[Q]: Provocative clinical tests are often performed in the diagnosis of ulnar neuropathy at the elbow (UNE) although the evidence for the usefulness of these tests is limited. The aim of this study was to determine the diagnostic value of provocative clinical tests in the diagnosis of UNE in a relevant spectrum of patients and controls.', "A prospective cohort study was performed in consecutive patients clinically suspected of having UNE. All patients underwent a neurological examination and four commonly used provocative clinical tests (Tinel's test, flexion compression test, palpating for local ulnar nerve tenderness and nerve thickening). Subsequently, in all patients a reference standard test comprising electrophysiological studies and neurosonography was independently assessed.", "192 eligible patients completed the study protocol. UNE was diagnosed in 137 and an alternative diagnosis was made in 55 patients. The sensitivity, specificity, and positive and negative predictive values were as follows: Tinel's test 62%, 53%, 77% and 30%; flexion compression test 61%, 40%, 72% and 29%; palpating for nerve thickening 28%, 87%, 84% and 33%; and palpating for nerve tenderness 32%, 80%, 80% and 32%. Logistic regression and receiver operating characteristic curves showed that the added value of one or more provocative tests over routine clinical examination is minimal.
