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.

[EX Q]: Granulocyte-colony stimulating factor (G-CSF) is used for the mobilization of bone marrow and endothelial progenitor cells, though G-CSF-induced inflammation may cause endothelial dysfunction. We examined the effects of G-CSF on endothelium, C-reactive protein (CRP), tumour necrosis factor-alpha (TNF-alpha) and anti-inflammatory cytokines namely interleukin 10 (IL-10).', 'We studied 60 women with breast cancer, who were randomized to either subcutaneous G-CSF (5 microg/kg), o.d. for 5 days after adjuvant chemotherapy (n = 40) or placebo (n = 20).', 'We measured flow-mediated dilatation (FMD%) of the brachial artery by ultrasonography, CRP, TNF-alpha, IL-10 and the ratio TNF-alpha/ IL-10 blood levels before, 2-h and 5-days after the G-CSF or placebo treatment.', 'There was a greater increase of FMD, IL-10 and reduction of TNF-alpha/ IL-10, 2 h and 5 days after the G-CSF treatment compared to placebo. Although, CRP and TNF-alpha were higher, TNF-alpha/IL-10 was lower at the end of G-CSF treatment compared to placebo. Improvement of FMD was related to changes of IL-10 and TNF-alpha/IL-10.
[EX A]: Is treatment with granulocyte colony stimulating factor associated with improvement in endothelial function?

[EX Q]: To evaluate whether the relationship between dietary composition and plasma lipid levels is genetically determined.', 'We have evaluated the influence of common apolipoprotein A5 (APOA5) variants (T-1131 > C, Ser19 > Trp and Val153 > Met) on plasma lipid concentrations in 117 males for whom dietary composition markedly changed and total cholesterol decreased (from 6.21 +/- 1.31 mmol/L in 1988 to 5.43 +/- 1.06 mmol/L in 1996) over an 8 year follow-up study.', 'APOA5 T-1131 > C and Val153 > Met variants did not influence the change in lipid measures over time. In Ser/Ser19 homozygotes, the plasma cholesterol was relatively stable over the years (6.1 +/- 1.2 mmol/L in 1988 and 5.6 +/- 1.0 mmol/L in 1996, -8%, P < 0.01). In contrast, in the Trp19 carriers, the decrease of the plasma cholesterol was more than 20% (6.5 +/- 1.6 mmol/L in 1988 and 5.1 +/- 1.0 mmol/L in 1996) (P < 0.001). The difference of the changes is significant (8% vs. 20%, P < 0.005). Changes in other analyzed lipid parameters have not been significantly associated with APOA5 variants.

[EX Q]: Cognitive decline is part of the long-term outcome for many individuals with bipolar disorder (BD). The ε4 allele (APOE*4) of apolipoprotein E (APOE) is a well-established risk factor for dementia in Alzheimer's disease (AD). However, its contribution to the risk of cognitive deterioration in BD has not yet been determined. Our aim was to analyze the APOE genotype association with cognitive status in a sample of older adults with BD and compare this to the association in individuals with AD, individuals with mild cognitive impairment (MCI), and healthy controls.", "Participants (n\xa0=\xa0475) were allocated to four groups: individuals with BD (n\xa0=\xa077), those with AD (n\xa0=\xa0211), those with MCI (n\xa0=\xa043), and healthy controls (n\xa0=\xa0144) according to clinical and neuropsychological assessment. APOE was genotyped by real-time polymerase chain reaction. Tukey's honest significant difference test and Pearson's chi-squared test were used to compare diagnostic groups.", 'Subjects with BD were similar to controls with respect to the distribution of the APOE genotype (p\xa0=\xa00.636) and allele frequencies (p\xa0=\xa00.481). Significant differences were found when comparing the AD group to the BD group or to controls (APOE genotype: p\xa0<\xa00.0002; allele frequencies: p\xa0<\xa00.001). APOE*4 was significantly increased in the AD group when compared to the BD group (p\xa0=\xa00.031) and controls (p\xa0<\xa00.0001). The cognitively impaired BD subgroup (Mini-Mental State Examination below the cutoff score and/or neuropsychological assessment compatible with MCI) had a statistically significant higher frequency of APOE*2 compared to the AD group (p\xa0=\xa00.003).
