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:
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.

question:
Obesity has shown a positive association with depression. We aimed to investigate the relationships among body weight, body mass index (BMI=kg/m(2)), change in a depression rating scale, and change in a functional scale with fluoxetine treatment for hospitalized patients with major depressive disorder (MDD).', 'A total of 131 acutely ill inpatients with MDD were enrolled to receive 20mg of fluoxetine daily for 6 weeks. The 17-item Hamilton Depression Rating Scale (HAMD-17) for symptom and the Work and Social Adjustment Scale (WSAS) for functioning were assessed at weeks 0, 1, 2, 3, 4, and 6. Remission was defined as a score of≤7 on the HAMD-17 at endpoint. Body weight, body length, and BMI were measured at baseline. Pearson correlation coefficients (r) were calculated among body weight, BMI, HAMD-17 score change, and WSAS score change.', 'Of the 131 participants, 126 (96.2%) had at least one post-baseline assessment and were included in the analysis. Significant differences in body weight and BMI existed between remitters and nonremitters. There were statistically significant relationships among baseline body weight, baseline BMI, HAMD-17 score change, and WSAS score change at end point.

question:
Raloxifene is a selective estrogen receptor (ER) modulator (SERM) used for the treatment of osteoporosis. However, its efficacy and also its safety vary greatly among treated patients, and it might be influenced by the individuals' genetic background. As the receptor activator of the nuclear factor κB (RANK) ligand (RANKL)/RANK/osteoprotegerin (OPG) system is essential for osteoclastogensis and Wnt signaling pathway for osteoblastogenesis, we decided to evaluate the raloxifene treatment in regard to selected polymorphisms in key genes of these two main bone regulatory pathways.", 'Fifty-six osteoporotic postmenopausal women treated with raloxifene were genotyped for 11 polymorphisms located in six genes: -290C>T, -643C>T, and -693G>C in tumor necrosis factor receptor superfamily member 11 (TNFSF11), +34694C>T, +34901G>A, and +35966insdelC in tumor necrosis factor receptor superfamily member 11A (TNFRSF11A), K3N and 245T>G in tumor necrosis factor receptor superfamily member 11B (TNFRSF11B), A1330V in LRP5, I1062V in LRP6, and -1397_-1396insGGA in SOST. For evaluation of treatment efficacy, bone mineral density (BMD) and biochemical markers of bone turnover were measured.', 'One-year change in total hip BMD was associated with +34901G>A in TNFRSF11A (p=0.040), whereas, for lumbar spine BMD, the association was shown for -1397_-1396insGGA in SOST (p=0.015). C-terminal crosslinking telopeptides of type I collagen (CTX) concentrations showed significant association with -643C>T single nucleotide polymorphism (SNP) in TNFSF11 (p=0.049) and +34694C>T in TNFRSF11A (p=0.022). No other association was found between 1-year change in BMDs or biochemical markers and the studied SNPs.
