TASK DEFINITION: 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.
PROBLEM: 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-B 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-B activation and downstream proinflammatory mediator production. Knocking down IRAK4 in microglia significantly decreased the IRAK4 expression and inhibited the NF-B 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.

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

PROBLEM: Prepubertal children and early adolescents with bipolar disorders (PEA-BP) who participate in the ongoing study "Phenomenology and Course of Pediatric Bipolar Disorders" have a high prevalence of ultradian (within 24-hour periods) rapid cycling. Based on a case-control finding reported in bipolar (BP) adults of an association between rapid and ultradian rapid cycling with the low-activity allele of catechol-O-methyltransferase (l-COMT), study of linkage and linkage disequilibrium of l-COMT in the PEA-BP population seemed warranted.', "Genotypes on a subset of the larger PEA-BP sample, for whom trio blood collection was complete (i. e., probands and both of their biological parents), were used to perform transmission disequilibrium tests (TDTs). Diagnoses were established from a comprehensive battery that included WASH-U-KSADS (Washington University Kiddie Schedule for Affective Disorders and Schizophrenia) given to both mothers and children and from consensus conferences. Probands with PEA-BP (N = 52) were 10.9 +/- 2.8 years old at index episode; had a mean age of BP onset at 8.0 +/- 3.8 years; were severely impaired, with a mean Children's Global Assessment Scale score of 44.5 +/- 8.9; and manifested the cardinal features of BP (84.6% had euphoric mood, 76.9% had grandiosity, and 57.7% had psychosis). Ultradian rapid cycling occurred in 75%. Genotyping of the single nucleotide polymorphism at COMT was performed using automated capillary electrophoresis single-strand conformational polymorphism with detection by laser-induced fluorescence.", 'Transmission disequilibrium tests were not significant for preferential transmission of l-COMT for the ultradian rapid-cycling subgroup or for the entire PEA-BP sample.

SOLUTION: Is ultradian rapid cycling in prepubertal and early adolescent bipolarity in transmission disequilibrium with val/met COMT alleles?

PROBLEM: Are the results of cemented titanium hip arthroplasty as bad as described in literature? We present the 10-year results of a cemented mild grid blasted Titanium-Aluminium-Vanadium Stem in Total-Hip-Arthroplasty.', 'The clinical and radiological reexamination was documented in standardized questionnaire in which several scores were integrated. All X-rays were stored and analysed by a special hardware and software computer system.', "35% of all patients could be reexamined both clinically and roentgenologically. 71 patients were male (mean age 56.1 years) and 130 female (mean age 59.3 years). The average follow-up period was 11 years and 4 months. The mean Merle d'Aubigne hip score increased from 10.5 to 16.0 points at the follow-up evaluation. Radiolucent lines were according to the zones of Gruen seen in 1% to 22% depending on the zone and the size of the femoral component. 18 reoperations of the femoral component (2.9%) had to be performed. The survivorship analysis (Kaplan-Meier) showed a 95.4% survival of the femoral component after 10 years.

SOLUTION:
Does [ 10 year result with a cemented fine-grit-blasted titanium-aluminum-vanadium hip endoprosthesis shaft ]?
