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]: Context: MicroRNAs play important roles in regulation of the initiation and progression of AML. MiR-210 is closely related with cancer development; however, whether miR-210 expression level correlates with clinical correlation in AML is unknown. Thus, the aim of this study was to investigate the potential relationship between miR-210 expression and AML prognosis.', 'Real-time quantitative PCR was carried out to examine the expression level of miR-210 in bone marrow and serum obtained from AML patients and healthy controls. Then the correlation between miR-210 expression and a variety of important clinical parameters (such as overall survival, relapse-free survival, and prognostic value) were further studied.', 'The expression level of miR-210 was significantly higher in the bone marrow and serum of AML patients than that of healthy controls (p<0.001). Moreover, miR-210 expression was associated with various AML clinicopathological parameters, including FAB classification and cytogenetics. The serum miR-210 expression level was reduced significantly when the patients achieved complete remission (p=0.02). The high miR-210 expression group had both poorer relapse-free survival (p=0.015) and worse overall survival (p=0.008). In the multivariate analysis model, miR-210 was identified as an independent prognostic marker.
Answer: MiR-210 up-regulation was associated with poor prognosis in AML and it might be useful as a marker for predicting the clinical outcome of AML patients.

[EX Q]: Context: Immunologic abnormalities have been found in bipolar disorder but pentraxin 3, a marker of innate immunity, has not been studied in this population.', 'Levels of pentraxin 3 were measured in individuals with bipolar disorder, schizophrenia, and non-psychiatric controls. Linear regression models were used to compare the pentraxin 3 levels in each of the psychiatric groups to that in the control group, adjusting for demographic and clinical variables. Logistic regression models were used to calculate the odds ratios associated with levels of pentraxin 3 which differed from specified levels of the control group.', 'The sample consisted of 831 individuals: 256 with bipolar disorder, 309 with schizophrenia, and 266 without a psychiatric disorder. The levels of pentraxin 3 in the bipolar disorder, but not in the schizophrenia, group were significantly lower than those of controls, adjusting for age, gender, race, maternal education, smoking status, and body mass index (t = -3.78, p < 0.001). The individuals with bipolar disorder also had significantly increased odds of having low levels of pentraxin 3 relative to both the 10th and 25th percentile level of the controls and significantly decreased odds of having a level greater than the 75th and the 90th percentile level of the controls, adjusting for the same covariates.
Answer: Individuals with bipolar disorder have low levels of pentraxin 3 which may reflect impaired innate immunity. An increased understanding of the role of innate immunity in the etiopathogenesis of bipolar disorder might lead to new modalities for the diagnosis and treatment of this disorder.

[EX Q]: Context: To determine whether frontal white matter diffusion abnormalities can help predict acute executive function impairment after mild traumatic brain injury (mTBI).', 'This study had institutional review board approval, included written informed consent, and complied with HIPAA. Diffusion-tensor imaging and standardized neuropsychologic assessments were performed in 20 patients with mTBI within 2 weeks of injury and 20 matched control subjects. Fractional anisotropy (FA) and mean diffusivity (MD) images (imaging parameters: 3.0 T, 25 directions, b = 1000 sec/mm(2)) were compared by using whole-brain voxelwise analysis. Spearman correlation analyses were performed to evaluate associations between diffusion measures and executive function.', 'Multiple clusters of lower frontal white matter FA, including the dorsolateral prefrontal cortex (DLPFC), were present in patients (P < .005), with several clusters also demonstrating higher MD (P < .005). Patients performed worse on tests of executive function. Lower DLPFC FA was significantly correlated with worse executive function performance in patients (P < .05).
Answer: Impaired executive function following mTBI is associated with axonal injury involving the DLPFC.
