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.

Example 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 ]?
Example 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.

Example Input: Context: Nestin is a type VI intermediate filament protein known as a marker for progenitor cells that can be mostly found in tissues during the embryonic and fetal periods. In our study, we aimed to determine the expression of nestin in meninges covering the brain tissue at different developmental stages and in the new born.', 'In this study 10 human fetuses in different development stages between developmental weeks 9-34 and a newborn brain tissue were used. Fetuses in paraffin section were stained with H+E and nestin immunohistochemical staining protocol was performed.', 'In this study, in the human meninges intense nestin expression was detected as early as in the 9th week of development. Intensity of this expression gradually decreased in later stages of development and nestin expression still persisted in a small population of newborn meningeal cells.\Question: Is intermediate filament protein nestin expressed in developing meninges?
Example Output: In the present study, nestin positive cells gradually diminished in the developing and maturing meninges during the fetal period. This probably depends on initiation of a decrease in nestin expression and replacement with other tissue-specific intermediate filaments while the differentiation process continues. These differences can make significant contributions to the investigation and diagnosis of various pathological disorders (Tab. 1, Fig. 3, Ref. 36).

Example Input: Context: Emerging evidence has indicated the bad effect of periodontal inflammation on diabetes control. However, the exact regulatory mechanisms within the association between periodontitis and diabetic development remain unclear. This study aims to investigate the function of microRNAs in regulating periodontitis-induced inflammation in an obese rat model.', 'Experimental periodontitis was introduced into OLETF and LETO rat. Intraperitoneal glucose tolerance test was performed to detect diabetic development. Serum cytokines levels and microRNAs expression were detected by ELISA and RT-PCR analysis respectively. And, macrophages were isolated for gain- and loss-of-function studies, to investigate the regulatory mechanism of miR-147 in periodontitis-induced inflammation.', 'Periodontitis induced proinflammatory response with classical activated macrophages in both rats, but distinctively aggravated the impaired glucose tolerance of OLETF rat with spontaneous type 2 diabetes. Analysis for serum microRNAs expression showed the distinctive and synergistic upregulation of miR-147 with periodontitis-induced effects in rats, while further experiments demonstrated the positive regulatory mechanism of miR-147 on classical activated macrophages with overexpressed proinflammatory markers, showing M1 phenotype.\Question: Does periodontitis promote the diabetic development of obese rat via miR-147 induced classical macrophage activation?
Example Output:
This study provided new evidence for the positive effect of periodontal inflammation on diabetic development, while the regulatory mechanism of miR-147 on classical macrophage activation, was verified, and presumed to contribute to the impaired glucose tolerance aggravated by periodontitis in obese rats. Besides, this study indicated the application of miR-147 for therapeutic approach in the treatment of diabetes with periodontitis.
