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.

Example Input: Context: Genetic haploinsufficiency of SYNGAP1/Syngap1 commonly occurs in developmental brain disorders, such as intellectual disability, epilepsy, schizophrenia, and autism spectrum disorder. Thus, studying mouse models of Syngap1 haploinsufficiency may uncover pathologic developmental processes common among distinct brain disorders.', 'A Syngap1 haploinsufficiency model was used to explore the relationship between critical period dendritic spine abnormalities, cortical circuit assembly, and the window for genetic rescue to understand how damaging mutations disrupt key substrates of mouse brain development.', 'Syngap1 mutations broadly disrupted a developmentally sensitive period that corresponded to the period of heightened postnatal cortical synaptogenesis. Pathogenic Syngap1 mutations caused a coordinated acceleration of dendrite elongation and spine morphogenesis and pruning of these structures in neonatal cortical pyramidal neurons. These mutations also prevented a form of developmental structural plasticity associated with experience-dependent reorganization of brain circuits. Consistent with these findings, Syngap1 mutant mice displayed an altered pattern of long-distance synaptic inputs into a cortical area important for cognition. Interestingly, the ability to genetically improve the behavioral endophenotype of Syngap1 mice decreased slowly over postnatal development and mapped onto the developmental period of coordinated dendritic insults.
Answer: Pathogenic Syngap1 mutations have a profound impact on the dynamics and structural integrity of pyramidal cell postsynaptic structures known to guide the de novo wiring of nascent cortical circuits. These findings support the idea that disrupted critical periods of dendritic growth and spine plasticity may be a common pathologic process in developmental brain disorders.
Example Output: Does syngap1 haploinsufficiency damage a postnatal critical period of pyramidal cell structural maturation linked to cortical circuit assembly?

Example Input: Context: The present study was undertaken to determine whether exposure of the sclera to prostaglandin (PG)F(2alpha) or to the PGF(2alpha) analogue latanoprost acid alters mRNA for matrix metalloproteinases.', 'Fifteen human eye bank eyes were studied. Circular pieces of sclera were either immediately preserved in a stabilization reagent or cultured in low-serum DMEM/F-12 medium. The cultures were treated for 24 hours with medium supplemented with PGF(2a), latanoprost acid, or vehicle. Total RNA was then isolated, and the expression of mRNA for matrix metalloproteinase (MMP)-1, -2, -3, -8, -9, -10, and -12 were determined by real-time PCR. All results were normalized according to the GAPDH mRNA in each sample. Altered mRNA expression after PG treatments also was evaluated with microarrays containing 19 MMP genes and 4 tissue inhibitor of matrix metalloproteinase (TIMP) genes.', 'Real-time PCR results showed that 24 hours of exposure to 100 nM PGF(2alpha) significantly increased mRNA for MMP-1 and -9 (P < 0.06 Wilcoxon test) and that exposure to 100 nM latanoprost acid significantly increased mRNA for MMP-9 (P < 0.06 Wilcoxon test). Array analysis demonstrated increases of MMP-3 and -10 mRNA after exposure to 100 nM latanoprost and further increases after exposure to 200 nM latanoprost. The array results also showed that latanoprost induced dose-dependent increases in the expression of TIMP-1, -2, and -3 mRNA in the scleral cultures.
Answer: PGF(2alpha) and latanoprost acid induce coordinated alterations of MMP gene transcription in scleral organ cultures. These results indicate that PGs can directly trigger MMP gene transcription changes within the sclera. These changes support a role for increased MMPs in the enhancement of uveoscleral outflow that occurs after topical treatment with latanoprost.
Example Output: Do prostaglandin FP agonists alter metalloproteinase gene expression in sclera?

Example Input: Context: Due to recent war situation in neighboring country we have witnessed large number of victims with post-traumatic false (pseudo) aneurysms of head and neck in roadside bomb blast victims in Pakistan. Thus through this observational retrospective study we aim to share our experience of managing these patients.', "5 years patients' case records, from June 2008-June 2013, were reviewed from the hospital's records. 14 cases of roadside bomb blast victims, developing false aneurysms of major or minor vessels of head and neck, were studied. We excluded the post-traumatic pseudoaneurysms involving other sites and vessels of the body. We observed the mechanism, the duration of presentation, symptoms/signs, vessels involved, complications and the management done.", 'All 14 cases presented with a localized pulsatile swelling with tenderness in the course of a known artery and with an overlying entry site wound from bomb blast sharp nails. Men were affected more as compared to women. All (14) cases had 2-12 weeks of duration between the injury and presentation. Temporal artery (4) was involved in most cases followed by common carotid artery (3). Open surgery was treatment of choice in 12 (85.7%) of cases; however 2 (14.3%) patients had endovascular intervention to correct the pathology. Post-operatively all patients recovered completely, without any major or minor complications.
Answer: Surgical intervention remains the management of choice for post-traumatic false aneurysms of head and neck in Pakistan. Despite the benefits of endovascular procedures, improvements must be weighed against the added costs on the patients.
Example Output:
Does pseudoaneurysm of head and neck vessels have been frequently observed in road side bomb blast victims?
