Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: B-type natriuretic peptide (BNP) and N-terminal-pro-BNP (NT-pro-BNP) are important diagnostic tools for patients with suspected cardiac disorders. The aim of this study was to evaluate the predictive value of plasma NT-pro-BNP in identifying cardiac metastases in patients with non-small cell lung cancer (NSCLC) and dyspnoea.', 'A total of 120 patients, median age 62 years (range 46-83), with NSCLC and dyspnoea were studied. Patients with heart failure or documented coronary artery disease were excluded. Echocardiographic imaging was used to detect cardiac metastases and estimate global left ventricular function. Ejection fraction and E/A ratio from transmitral inflow pattern were calculated. Plasma NT-pro-BNP was also measured. 72 patients (72/120, 60%) with cardiac metastases were identified.', 'NT-pro-BNP was significantly higher in patients with metastases (1347.5 +/- 1004.30 pg/ml vs. 159.02 +/- 93.29 pg/ml; p = 0.001). No differences between groups, regarding s-creatinine (p = 0.45), haemoglobin (p = 0.71), left ventricular hypertrophy (p = 0.91), and diastolic dysfunction (p = 0.79), were observed.

Answer: Is pro-brain natriuretic peptide a sensitive marker for detecting cardiac metastases in patients with non-small cell lung cancer?

Question: The antidepressant drug fluoxetine (FLU) is considered in the group of selective serotonine re-uptake inhibitors. Its distribution in brain and binding to human brain glutathione S-transferase- (GST-) have been shown. FLU can cross blood brain barrier and placenta, accumulate in fetus and may cause congenital malformations.', 'To elucidate the interaction of placental GST- with FLU.', 'First, concentration-dependent inhibition of human placental GST- was evaluated by using different FLU concentrations and then 0.3125, 0.625, 1.25, 2.5 and 5mM FLU concentrations were chosen and tested while keeping GSH concentration constant and 1-chloro-2,4-dinitrobenzene (CDNB) concentration varied and vice versa. The data were evaluated with different kinetic models and Statistica 9.00 for Windows.', 'The Vm, at variable [CDNB] (14216U/mg protein) was 3 times higher than the Vm obtained at variable [GSH] (494U/mg protein). On the other hand, the Km for CDNB was 10 times higher than the Km for GSH (1.990.36mM versus 0.210.06mM). The IC50 value for FLU was 8.6mM. Both at constant [CDNB] and variable [GSH] and at constant [GSH] and variable [CDNB] the inhibition types were competitive with the Ki values of 5.624.37 and 8.091.27mM, respectively.

Answer: Does fluoxetine-induced toxicity result in human placental glutathione S-transferase- ( GST- ) dysfunction?

Question: In amyotrophic lateral sclerosis (ALS), symptoms apparently spread following regional rules, and depending on the site of onset. We examined if respiratory function deterioration appears earlier or is more severe in patients with upper-limb onset.', 'We compared the results of various pulmonary function tests (PFT) obtained at diagnosis depending on the site of onset in 49 ALS patients. In a longitudinal study, we compared the deterioration of forced vital capacity (FVC) in relation to the site of onset, and analyzed the time elapsed to reach values below 80% of predicted according to site of onset, and we compared the survival depending on the site of onset.', 'No significant differences in PFT were found in the upper-limb onset group in any of the analysis performed. No differences in survival were detected in any disease onset group.

Answer:
Is respiratory function deterioration time-linked with upper-limb onset in amyotrophic lateral sclerosis?
