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.

Input: Consider Input: To determine the prognostic role of co-morbidity in medically inoperable early-stage non-small cell lung cancer (NSCLC) treated with stereotactic body radiotherapy (SBRT).', "Between 2000 and 2007, 88 consecutive early-stage medically inoperable NSCLC patients were treated by linac-based SBRT. The dose was either 45 Gy or 67.5 Gy in three fractions prescribed to the isocenter. Baseline co-morbidities were retrospectively retrieved by consultation of a formal electronic registry of diagnoses as well as patients' charts. The age-adjusted Charlson Co-morbidity Index (CCI) was scored for each patient and subjected to univariate and multivariate analysis.", 'With a median follow-up of 44 months, the actuarial local control rate at 4 years was 89% while the median overall survival was 22 months. The median age-adjusted CCI score was 5. The age-adjusted CCI was a significant predictor of overall survival on both univariate (p=0.002) and multivariate analysis (p=0.011). Patients with an age-adjusted CCI score of 3 or less had a median survival of 41 months versus only 11 months for those scoring 6 or more.

Input: Consider Input: FoxO transcription factors have been reported to play pivotal roles in tumorigenesis and drug resistance. The mechanisms underlying the tumor suppression function of FoxOs in human cancers remain largely unknown. Aberrant expression and activation of Nrf2 often correlate with chemoresistance and poor prognosis. Here, we report that FoxO3 directs the basal transcription of Kelch-like ECH-associated protein 1 (Keap1), an adaptor protein that bridges Nrf2 to Cul3 for degradation. FoxO3 depletion resulted in Keap1 down-regulation, thereby activating Nrf2 signaling. We further demonstrated that inhibition of the FoxO3-Keap1 axis accounts for Nrf2 induction and activation induced by constitutively active AKT signaling or tumor necrosis factor α treatment. Unlike previous findings, FoxO3 silencing led to decreased reactive oxygen species production, therefore protecting cells from oxidative stress-induced killing in an Nrf2-dependent manner. Importantly, FoxO3 deficiency strongly potentiated tumor formation in nude mice and rendered cholangiocarcinoma xenografts resistant to cisplatin-induced cell death by activating Nrf2. Additionally, we found that clinical cholangiocarcinoma samples displayed FoxO3-Keap1 down-regulation and Nrf2 hyperactivation, underscoring the essential roles of these proteins in cholangiocarcinoma development.

Input: Consider Input: Exogenous leptin markedly decreased plasma paraoxonase (PON1) activity in rats. Hyperleptinemia and decreased PON1 activity have previously been demonstrated in uremia. Therefore, we investigated the relationship between leptin level and PON1 activity in hemodialysis (HD) patients.', 'Leptin and PON1 were determined in 40 HD patients and 40 age-matched controls with similar body mass index (BMI).', 'Leptin was higher (p < 0.001) and PON1 activity was lower (p < 0.001) in HD patients than in controls. PON1 and PON1/HDL ratio was higher in HD patients with BMI >25 kg/m2 than in HD patients with BMI <25 kg/m2. It was not due to a difference in frequency of high activity phenotype of PON1 among subgroups of HD patients. There was no similar difference in controls. Spearman analysis showed a significant correlation between leptin and PON1 activity (p < 0.02), BMI (p < 0.001), triglyceride (TG) (p < 0.03), and Kt/V (-0.323, p < 0.03), but multiparametric regression analysis did not reveal it. PON1 activity depended on BMI in both models. In controls, leptin correlated with BMI (p < 0.001) and TG (p < 0.002) but not PON1 activity. A slight decrease in leptin concentration and PON1 activity during HD was observed.
