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.

Input: Consider Input: The purpose was to investigate whether patient-specific factors (PSF) and surgically modifiable factors (SMF), measured by means of a computer-assisted navigation system, can predict the Knee Society Scores (KSS) after total knee arthroplasty (TKA).', 'Data from 99 patients collected during a randomized clinical trial were used for this secondary data analysis. The KSS scores of the patients were measured preoperatively and at 4-years follow-up. Multiple regression analyses were performed to investigate which combination of variables would be the best to predict the 4-years KSS scores.', 'When considering SMF alone the combination of four of them significantly predicted the 4-years KSS-F score (p\u2009=\u20090.009), explaining 18\xa0% of its variation. When considering only PSF the combination of age and body weight significantly predicted the 4-years KSS-F (p\u2009=\u20090.008), explaining 11\xa0% of its variation. When considering both groups of predictors simultaneously the combination of three PSF and two SMF significantly predicted the 4-years KSS-F (p\u2009=\u20090.007), explaining 20\xa0% of its variation.

Output: Do surgically modifiable factors measured by computer-navigation together with patient-specific factors predict knee society score after total knee arthroplasty?


Input: Consider Input: To explore the effect of arsenic trioxide (As2O3) on the growth inhibition of imatinib (IM)-resistant bcr-abl mutant cell lines in vitro.', 'Cell growth of one IM-sensitive cell line, 32Dp210 and 15 IM-resistant cell lines including T315I and other 14 bcr-abl mutants were detected by MTT assay after treatment with IM and As2O3. The cell lines with 5 frequently observed mutants in CML patients were analyzed for apoptosis by flow cytometry with Annexin V and PI staining as well as the expression of bcr-abl fusion protein, phosphorylated CRKL protein and apoptosis-related proteins by Western blot.', 'The fifty percent inhibition concentration (IC50) values of As2O3 for 15 IM-resistant cell lines were 2.6-5.3 fold lower than that for IM-sensitive cell line. For the 5 bcr-abl mutants frequently happened in CML patients, As2O3 significantly inhibited the expression of bcr-abl fusion protein and phosphorylated CRKL and induced apoptosis in a dose-dependent manner as compared with that for 32Dp210. Coincidently, the cell apoptosis was induced through caspase-3, 8 and 9 pathways.

Output: Does [ Arsenic trioxide inhibit cell growth in imatinib-resistant bcr-abl mutant cell lines in vitro ]?


Input: Consider Input: Lipodystrophies (LD) are genetic or acquired disorders sharing the symptom of partial or complete adipose tissue deficiency and a dysregulation of adipokines including leptin and adiponectin. Progranulin, an adipokine with proinflammatory and insulin resistance-inducing characteristics, has not been investigated in LD so far.', 'Circulating progranulin was determined in LD patients (N=37) and in age-, gender-, and body mass index-matched healthy control subjects (N=37). Additionally, we investigated progranulin expression in an LD mouse model as compared to wild-type mice. Moreover, we elucidated circulating progranulin before and during metreleptin supplementation in 10 patients with LD.', 'Median [interquartile range] circulating progranulin was increased in patients with LD (82.9 [25.9] μg/l) as compared to controls (73.6 [22.8] μg/l) (p=0.005). C-reactive protein (CRP) remained an independent and positive predictor of progranulin in multivariate analysis. Progranulin mRNA was significantly upregulated in all adipose tissue depots, i.e. visceral, subcutaneous, and brown adipose tissue, and in muscle of LD animals versus wild-type mice. Progranulin levels did not significantly change during metreleptin supplementation.


Output: Is progranulin increased in human and murine lipodystrophy?
