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: Circulation on blood extracorporeally through plastic tubing activates several pathways including systemic inflammation and oxidative stress. These phenomena are suspected to participate to neurological and cardiovascular side effects observed in the patients under cardiopulmonary bypass (CPB). A direct relationship, in diabetic patients, between hyperglycemia and morbidity and mortality has been established. However, it is still unclear whether perioperative hyperglycemia has a direct effect on adverse events in cardiac surgery. The purpose of this study was to determine the influence of hyperglycemia on inflammation and oxidative stress in patients under CPB during cardiac surgery.', 'Control patients (n=17) and diabetic (type 2) patients (n=13) were included in this study. Blood samples were drawn before, during and after the CPB. Oxidative stress was evaluated in the plasma by direct and indirect approaches. Direct detection of ascorbyl radicals was assessed by electron spin resonance spectroscopy. An index: ascorbyl radical/vitamin C ratio is an indicator of the degree of oxidative stress taking place in the plasma. Oxygen radical absorbing capacity (ORAC) values were used as measurement of antioxidant capacity of the plasma. To determine inflammation profile of patients, we measure the evolution of plasma concentration of interleukin 8 (IL-8).', 'During cross clamping and post-CPB, the index ascorbyl radical/vitamin C is increased; the value of the index is more significant in diabetic patients. Concomitantly, ORAC values decreased in all the patients during cross clamping (p<0.05). Results concerning inflammatory index showed that IL-8 levels increased during the CPB.\Question: Is [ Oxidative stress exacerbated in diabetic patients during cardiopulmonary bypass ]?

Ex Output:
In conclusion, the current study indicates that a systemic oxidative stress occurs during CPB and post-CPB periods and that in patients with type 2 diabetes mellitus, the systemic oxidative stress was increased.

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: Impaired resolution of acute inflammation results in development of chronic inflammatory disorders such as atherosclerosis, asthma and arthritis. Clearance of apoptotic neutrophils by M2 macrophages, the process termed efferocytosis, is critical for complete resolution of inflammation as it prevents secondary necrosis caused by disgorgement of toxic contents from apoptotic cells in the inflamed site. In the present study, we investigated the effect of docosahexaenoic acid (DHA) on efferocytosis.', 'To determine the effect of DHA on efferocytosis, murine macrophage-like RAW264.7 cells were co-incubated with apoptotic Jurkat T cells, and efferocytosis was assessed by flow cytometry. The expression and production of M1 and M2 markers were determined by RT-PCR, ELISA and flow cytometry. To demonstrate the involvement of peroxisome proliferator-activated receptor (PPAR) in DHA-mediated effects, siRNA against PPAR was utilized. The expression of PPAR was examined by semiquantitative reverse-transcription polymerase chain reaction (RT-PCR), Western blot analysis and immunocytochemistry. The PPAR activation was measured by the electrophilic gel shift assay.', 'DHA enhanced the efferocytic ability of RAW264.7 cells, and induced their M2 polarization. Notably, knockdown of PPAR abolished the stimulatory effect of DHA on M2 polarization as well as efferocytosis. Furthermore, lipopolysaccharide-induced production of pro-inflammatory cytokines was significantly inhibited by DHA, suggesting that DHA alters the macrophage phenotype in favor of M2 while it suppresses M1 polarization.\Question: Does docosahexaenoic acid induce M2 macrophage polarization through peroxisome proliferator-activated receptor activation?

Ex Output:
These findings indicate that DHA can promote resolution of inflammation by facilitating efferocytosis through M2 macrophage polarization. Therefore, DHA may have a therapeutic potential in the management of inflammatory diseases which are related to impaired resolution of inflammation.
