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]: Total bilirubin (TB) was recently recognized as an endogenous anti-inflammatory and anti-oxidant molecule. Uric acid (UA) takes part in cardiovascular diseases by inducing oxidative stress, inflammation, and endothelial dysfunction. We assessed the relationship between serum TB levels, serum UA levels, and inflammatory status assessed by neutrophil-to-lymphocyte ratio (N/L) and arterial stiffness and arterial wave reflection in patients with a clinical diagnosis of coronary artery disease (CAD).', 'We included 145 consecutive patients admitted with stable angina pectoris (SAP) or acute coronary syndrome (ACS). Blood samples were drawn at admission for complete blood count and biochemistry. Non-invasive pulse waveform analysis for the determination of augmentation index (AIx) and carotid-femoral pulse wave velocity (PWV) measurements were performed with the commercially available SphygmoCor system.', 'When patients were divided into tertiles of PWV and AIx, median N/L and median serum UA levels were the highest and mean TB levels were the lowest in the third tertile (p<0.001 for all). AIx and PWV were positively associated with serum UA and N/L and negatively associated with serum TB levels (p<0.001 for all). After adjustments for age, gender, heart rate, systolic blood pressure, and presence of diabetes, significant correlations persisted for N/L, UA, and TB in ACS patients (p<0.05). In the SAP group, TB was significantly negatively correlated with AIx and PWV, and UA was significantly positively correlated with PWV (p<0.05).

[Q]: Circular RNAs are a subclass of non-coding RNAs detected within mammalian cells. This study was designed to test the roles of a circular RNA circ-Foxo3 in senescence using in vitro and in vivo approaches.', 'Using the approaches of molecular and cellular biology, we show that a circular RNA generated from a member of the forkhead family of transcription factors, Foxo3, namely circ-Foxo3, was highly expressed in heart samples of aged patients and mice, which was correlated with markers of cellular senescence. Doxorubicin-induced cardiomyopathy was aggravated by ectopic expression of circ-Foxo3 but was relieved by silencing endogenous circ-Foxo3. We also found that silencing circ-Foxo3 inhibited senescence of mouse embryonic fibroblasts and that ectopic expression of circ-Foxo3 induced senescence. We found that circ-Foxo3 was mainly distributed in the cytoplasm, where it interacted with the anti-senescent protein ID-1 and the transcription factor E2F1, as well as the anti-stress proteins FAK and HIF1α.

[Q]: It has previously been shown that gefitinib-treated patients with epidermal growth factor receptor (EGFR) gene amplification or high polysomy had a statistically significant improvement in response, time to progression, and survival in non-small cell lung cancer (NSCLC). Only few studies utilizing anti-EGFR treatment in advanced esophageal adenocarcinomas have been performed and the results have been heterogeneous. The aim of this study was to evaluate EGFR-targeted therapy with gefitinib in esophageal adenocarcinoma with a high EGFR polysomy.', 'Novel esophageal cell lines PT6216 and LN6216c were established from primary tumor and lymph node metastasis of a patient with highly aggressive and metastatic adenocarcinoma. Pathological examination including tumor differentiation and prognostic marker analysis, immunohistochemical EGFR expression analysis, EGFR fluorescence in situ hybridization, and mutation analysis were performed. Response of novel cell lines to gefitinib treatment was evaluated by cell proliferation and vitality assays. Fifty-four esophageal adenocarcinoma specimens were evaluated for EGFR gene copy gain.', 'The primary tumor cell line PT6216 and the lymph node cell line LN6216c show a homogenously high polysomy for EGFR determined by FISH analysis. Cell proliferation and vitality are highly sensitive to the tyrosine kinase inhibitor gefitinib compared to esophageal control cells without a high polysomy for EGFR. High polysomy for EGFR was found in 35 % of patients.
