Given a passage with a context and an answer, 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]: Context: Developmental dyslexia (DD) is a complex heritable condition associated with impairments in multiple neurocognitive domains. Substantial heritability has been reported for DD and related phenotypes, and candidate genes have been identified. Recently, a candidate gene for human cognitive processes, that is, GRIN2B, has been found to be associated significantly with working memory in a German DD sample. In this study, we explored the contribution of six GRIN2B markers to DD and key DD-related phenotypes by association analyses in a sample of Italian nuclear families. Moreover, we assessed potential gene-by-environment interactions on DD-related phenotypes.', 'We carried out a family-based association study to determine whether the GRIN2B gene influences both DD as a categorical trait and its related cognitive traits in a large cohort of 466 Italian nuclear families ascertained through a proband affected by DD. Moreover, we tested the role of the selected GRIN2B markers and a set of commonly described environmental moderators using a test for G×E interaction in sib pair-based association analysis of quantitative traits in 178 Italian nuclear families.', 'Evidence for a significant association was found with the categorical diagnosis of DD, performance intelligence quotient, phonemic elision, and auditory short-term memory. No significant gene-by-environment effects were found.
Answer: Our results add further evidence in support of GRIN2B contributing toward DD and deficits in DD. More specifically, our data support the view that GRIN2B influences DD as a categorical trait and its related quantitative phenotypes, thus shedding further light on the etiologic basis and the phenotypic complexity of this disorder.

[EX Q]: Context: The ADAMTS13-von Willebrand factor (vWF) axis has been suggested to play a critical role in the pathophysiology of ischemia-reperfusion injury (IRI) in the heart or brain. Therefore, we aimed to investigate whether this axis was involved in the pathophysiology of IRI-induced acute kidney injury.', 'We performed renal IRI in ADAMTS13 knockout (KO) or wild type (WT) mice. Functional and histological kidney damage, and inflammation were compared and the effect of anti-vWF antibodies in ADAMTS13 KO mice was assessed.', 'Following IRI, the blood and kidney ADAMTS13 levels were significantly decreased. vWF expression was significantly upregulated in both the medulla and cortex of injured kidneys as shown by immunohistochemistry and western blot analyses. There was also an increased level of vWF dimers after IRI. In ADAMTS13 KO mice, kidney vWF levels were further increased and this was associated with greater endothelial and epithelial injury compared to WT mice, suggesting an important role of vWF in renal IRI. In addition, the number of Gr-1
Answer: Our data show that the ADAMTS13-vWF axis is partially involved in the pathophysiology of kidney IR, suggesting that regulating ADAMTS13- and vWF-dependent mechanisms could have therapeutic potential to limit renal IRI. This article is protected by copyright. All rights reserved.

[EX Q]: Context: Fingertip injuries are common and bear significant costs associated with treatment, lost work, and functional impairment. This study compared these factors in occupationally related fingertip injuries treated with becaplermin, a recombinant human platelet-derived growth factor, and those treated with surgical reconstruction.', 'This was a prospective controlled trial involving occupationally related fingertip injuries. Fifty men (ages 23-51) with full thickness, single fingertip injuries > or =1.5 cm(2) with or without phalangeal exposure and distal to the distal interphalangeal (DIP) joint were evaluated. Group I (n = 25) underwent treatment with daily topical becaplermin. Group II (n = 25) underwent surgical reconstruction with a skin graft or local soft tissue flap. Time to wound healing, time to return to work, associated treatment costs, and calculated functional impairment were recorded.', 'Patients in Group I returned to work in significantly less time than those in Group II-10 days versus 38 days respectively). The average calculated functional impairment in Group I was 10% versus 22% in Group II. Associated treatment costs in group A were 1580 +/- 145 US Dollars compared with 6750 +/- 785 US Dollars in Group II. All differences were statistically significant at p < 0.05
Answer: In this study, the functional and economic costs were significantly less when fingertip injuries were treated with topical becaplermin than when they were treated with surgical reconstruction. This information should allow emergency and acute care physicians to treat these injuries more efficaciously and conveniently.
