In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Ex Input:
Context: To study the pulmonary effects of aspirating a mixture of sucralfate in water and sucralfate in hydrochloric acid in an animal model of aspiration pneumonia.', 'Prospective, randomized, controlled study with repeated measures.', 'University research laboratory.', 'Thirty-two in situ, isolated, blood perfused porcine lung preparations.', 'Five control preparations received no aspiration. Twenty-seven preparations received a standard aspiration of 1.5 mL/kg body of a) distilled water (n = 5), b) sucralfate in distilled water (n = 8), c) 1/10 normal hydrochloric acid (n = 6), and d) mixture of sucralfate in distilled water and hydrochloric acid (n = 8).', 'The pH measurements were made of all aspirates. Lung weight, airway pressures, and pulmonary artery pressures were continuously monitored before and for 4 hrs after aspiration. Lung wet/dry weight ratio was measured at the completion of the study.', 'The pH of sucralfate mixed with distilled water was 4.9, pH of 1/10 normal hydrochloric acid was 1.0, and pH of equal volumes of a sucralfate-water suspension mixed with hydrochloric acid was 1.5. Airway pressures and pulmonary arterial pressures increased in all aspirate groups over time compared with those values of control lungs. Control lungs gained 18 +/- 3 (SEM) g over 4 hrs and the wet/dry ratio was 4.951 +/- 0.310. Lungs aspirating distilled water gained 147 +/- 49 g and the wet/dry ratio was 5.198 +/- 0.120. Lungs aspirating sucralfate and distilled water increased their weight by 109 +/- 30 g and the wet/dry ratio was 5.380 +/- 0.076. Lungs aspirating a suspension of sucralfate and water and hydrochloric acid were similar to lungs aspirating hydrochloric acid alone with weight increases of 265 +/- 30 g and 346 +/- 81 g, and the wet/dry ratio of 7.011 +/- 0.273 and 7.230 +/- 0.390, respectively.\Question: Does sucralfate reduce the risk of acid aspiration pneumonitis?

Ex Output:
Sucralfate has minimal acid buffering effect. Aspiration of sucralfate mixed with distilled water causes lung edema similar to aspiration of water alone. Aspiration of a sucralfate-water suspension mixed with hydrochloric acid causes severe lung edema. These results suggest that patients given sucralfate prophylaxis for stress ulceration are at risk for acid aspiration.

Context: Natural disasters expose entire communities to stress and trauma, leading to increased risk for psychiatric symptoms. Yet, the majority of exposed individuals are resilient, highlighting the importance of identifying underlying factors that contribute to outcomes.', "The current study was part of a larger prospective study of children in Long Island, New York (n = 260). At age 9, children viewed unpleasant and pleasant images while the late positive potential (LPP), an event-related potential component that reflects sustained attention toward salient information, was measured. Following the event-related potential assessment, Hurricane Sandy, the second costliest hurricane in United States history, hit the region. Eight weeks after the hurricane, mothers reported on exposure to hurricane-related stress and children's internalizing and externalizing symptoms. Symptoms were reassessed 8 months after the hurricane.", 'The LPP predicted both internalizing and externalizing symptoms after accounting for prehurricane symptomatology and interacted with stress to predict externalizing symptoms. Among children exposed to higher levels of hurricane-related stress, enhanced neural reactivity to unpleasant images predicted greater externalizing symptoms 8 weeks after the disaster, while greater neural reactivity to pleasant images predicted lower externalizing symptoms. Moreover, interactions between the LPP and stress continued to predict externalizing symptoms 8 months after the hurricane.\Question: Does neural Reactivity to Emotional Stimuli Prospectively predict the Impact of a Natural Disaster on Psychiatric Symptoms in Children?

Ex Output:
Results indicate that heightened neural reactivity and attention toward unpleasant information, as measured by the LPP, predispose children to psychiatric symptoms when exposed to higher levels of stress related to natural disasters, while greater reactivity to and processing of pleasant information may be a protective factor.


Ex Input:
Context: miR-155 is an oncogenic miRNA that is often overexpressed in cancer and is associated with poor prognosis. miR-155 can target several DNA repair factors, including RAD51, MLH1, and MSH6, and its overexpression results in an increased mutation frequency in vitro, although the mechanism has yet to be fully understood. Here, we demonstrate that overexpression of miR-155 drives an increased mutation frequency both in vitro and in vivo, promoting genomic instability by affecting multiple DNA repair pathways. miR-155 overexpression causes a decrease in homologous recombination, but yields a concurrent increase in the error-prone nonhomologous end-joining pathway. Despite repressing established targets MLH1 and MSH6, the identified mutation pattern upon miR-155 overexpression does not resemble that of a mismatch repair-deficient background. Further investigation revealed that all four subunits of polymerase delta, a high-fidelity DNA replication, and repair polymerase are downregulated at the mRNA level in the context of miR-155 overexpression. FOXO3a, a transcription factor and known target of miR-155, has one or more putative binding site(s) in the promoter of all four polymerase delta subunits. Finally, suppression of FOXO3a by miR-155 or by siRNA knockdown is sufficient to repress the expression of the catalytic subunit of polymerase delta, POLD1, at the protein level, indicating that FOXO3a contributes to the regulation of polymerase delta levels.\Question: Does miR-155 Overexpression promote Genomic Instability by Reducing High-fidelity Polymerase Delta Expression and Activating Error-Prone DSB Repair?

Ex Output:

Taken together, miR-155 overexpression drives an increase in mutation frequency via multifaceted impact on DNA damage response and DNA repair pathways.
