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 Input:
Intracerebral hemorrhage (ICH) induces microglial activation and the release of inflammatory cytokines, leading to inflammation in the brain. IRAK4, an essential component of the MyD88-dependent pathway, activates subsets of divergent signaling pathways in inflammation.', 'In the experiment, microglia were stimulated with erythrocyte lysates, and then miR-367, IRAK4, NF-ĸB activation and downstream proinflammatory mediator production were analyzed. In addition, inflammation, brain edema, and neurological functions in ICH mice were also assessed.', "Here, we report that ICH downregulated miR-367 expression but upregulated IRAK4 expression in primary microglia. We also demonstrate that miR-367 suppressed IRAK4 expression by directly binding its 3'-untranslated region. MiR-367 inhibited NF-ĸB activation and downstream proinflammatory mediator production. Knocking down IRAK4 in microglia significantly decreased the IRAK4 expression and inhibited the NF-ĸB activation and the downstream production of proinflammatory mediators. In addition, our results indicate that miR-367 could inhibit expression of proinflammatory cytokines, reduce brain edema, and improve neurological functions in ICH mice.

Ex Output:
Does microRNA367 negatively regulate the inflammatory response of microglia by targeting IRAK4 in intracerebral hemorrhage?


Ex Input:
The aim of this study was to review the impact of salvage external beam radiotherapy (EBRT) of postprostatectomy patients with long-term follow-up on biochemical-free recurrence (BFR) and metastatic-free survival, and to describe pathological and clinical predictors of outcome.', 'In the period 1987-2010, 76 postprostatectomy patients with biochemical and clinical recurrence received salvage EBRT. Patients were treated with conformal EBRT and 68 (90%) received a dose of 70 Gy; eight patients (10%) received a dose of 60-64 Gy. No patients received adjuvant or neoadjuvant androgen deprivation therapy in conjunction with salvage EBRT.', 'The median follow-up time after salvage EBRT was 82 months (range 5-192 months). Seventeen patients (22%) developed biochemical recurrence subsequent to postprostatectomy salvage EBRT during the observation time, and the overall 50 and 75 month actuarial BFR rates after salvage EBRT were 84% and 79%, respectively. Seven patients (9%) developed metastatic disease and two patients died of prostate cancer. Independent predictors of biochemical recurrence were seminal vesicle invasion (SVI) in the prostatectomy specimen (p < 0.05) and prostate-specific antigen doubling time (PSADT) of 6 months or less (p = 0.041) before salvage EBRT.

Ex Output:
Is prostate-specific antigen doubling time subsequent to radical prostatectomy a predictor of outcome following salvage external beam radiation therapy : a single-centre experience?


Ex Input:
Paraplegia can result from operations requiring transient occlusion of the thoracic aorta. A rat model of paraplegia with the characteristics of delayed paraplegia and transient ischemic dysfunction was developed to determine whether ischemic preconditioning (IPC) improved neurologic outcome.', 'Rats underwent balloon occlusion of the upper descending thoracic aorta. One group (2 minute IPC, n = 19) underwent 2 minutes of IPC and a second group (5 minute IPC, n = 19) had 5 minutes of IPC 48 hours before 10 minutes of occlusion. The control group (n = 31) had no IPC prior to 10 minutes of occlusion.', 'Paraplegia occurred in 68% of the control animals (21 of 31 paraplegic: 6 delayed and 15 immediate paraplegia). Both the 2-minute IPC and 5-minute IPC groups had a decreased incidence of paraplegia when compared to controls (32%, p = 0.011 and 26%, p = 0.009, respectively).

Ex Output:

Does ischemic preconditioning protect against paraplegia after transient aortic occlusion in the rat?
