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: The aim of this study was to evaluate the frequency of sympathetic versus parasympathetic neuropathy among type 1 and type 2 diabetic patients.', 'There were 43 patients with type 1 and 17 with type 2 diabetes who were investigated. Sympathetic nerve function was assessed by measurement of the vasoconstriction (VAC) index by laser Doppler perfusion imaging of a locally heated finger followed by indirect cooling. Parasympathetic nerve function was assessed by R-R interval variation during deep breathing as measured by the expiration/inspiration (E/I) ratio. Results were expressed as age-corrected z scores in SD; VAC index >1.64 SD and E/I ratio <-1.64 SD were considered abnormal.', 'VAC index was abnormal in 40% with type 1 and 41% with type 2 diabetes, whereas the E/I ratio was abnormal in 42% with type 1 and 65% with type 2 diabetes. There was a clear association between VAC index and E/I ratio among type 1 (rs=0.525; P=0.0002) but not among type 2 (rs=0.10) diabetic patients. Among type 2 diabetic patients, the degree of dysfunction was most severe regarding parasympathetic function (P=0.0167).
Example Output: Are sympathetic and parasympathetic neuropathy frequent in both type 1 and type 2 diabetic patients?

Example Input: MicroRNA-222 (miR-222) has been shown to play a potential oncogenic role in bladder cancer. The aim of this study was to evaluate the expression of miR-222 in bladder cancer and its potential relevance to clinicopathological characteristics and patient survival.', 'Surgical specimens of cancer tissue and adjacent normal tissue were obtained from 97 patients with bladder cancer. The relative expression levels of miR-222 in the cancer and the normal adjacent tissue were measured by quantitative reverse-transcriptase PCR. We analyzed their correlation with clinicopathological parameters and prognostic value.', 'The expression level of miR-222 was significantly higher in tumor tissues than in corresponding non-cancerous tissues (5.461.45 versus 1.920.65, P< 0.0001), and a high expression of miR-222 was found to be significantly associated with tumor grade (P=0.003) and tumor stage (P=0.005). The miR-222 expression level was classified as high or low in relation to the median value (cutoff value=5.15). Kaplan-Meier analysis showed that patients with higher levels of miR-222 had significantly poorer survival than those with lower expression of this miRNA in patients, with a 5-year overall survival of 29.53% and 52.75%, respectively (P=0.0034). In the multivariate Cox proportional hazards analysis, which included miR-222 level, tumor grade, tumor stage, and tumor number, high miR-222 expression was independently associated with poor survival (P<0.001; hazard ratio 6.17; 95% CI 2.33 to 10.39).
Example Output: Is increased expression of miR-222 associated with poor prognosis in bladder cancer?

Example Input: The lung is exposed to airborne fungal spores, and fungi that colonize the oral cavity such as Candida albicans, but does not develop disease to opportunistic fungal pathogens unless the immune system is compromised. The Group IVA cytosolic phospholipase A2 (cPLA2) is activated in response to Candida albicans infection resulting in the release of arachidonic acid for eicosanoid production. Although eicosanoids such as prostaglandins and leukotrienes modulate inflammation and immune responses, the role of cPLA2 and eicosanoids in regulating C. albicans lung infection is not understood.', 'The responses of cPLA2(+/+) and cPLA2(-/-) Balb/c mice to intratracheal instillation of C. albicans were compared. After challenge, we evaluated weight loss, organ fungal burden, and the recruitment of cells and the levels of cytokines and eicosanoids in bronchoalveolar lavage fluid. The ability of macrophages and neutrophils from cPLA2(+/+) and cPLA2(-/-) mice to recognize and kill C. albicans was also compared.', 'After C. albicans instillation, cPLA2(+/+) mice recovered a modest weight loss by 48h and completely cleared fungi from the lung by 12h with no dissemination to the kidneys. In cPLA2(-/-) mice, weight loss continued for 72h, C. albicans was not completely cleared from the lung and disseminated to the kidneys. cPLA2(-/-) mice exhibited greater signs of inflammation including higher neutrophil influx, and elevated levels of albumin and pro-inflammatory cytokines/chemokines (IL1, IL1, TNF, IL6, CSF2, CXCL1, CCL20) in bronchoalveolar lavage fluid. The amounts of cysteinyl leukotrienes, thromboxane B2 and prostaglandin E2 were significantly lower in bronchoalveolar lavage fluid from C. albicans-infected cPLA2(-/-) mice compared to cPLA2(+/+) mice. Alveolar macrophages and neutrophils from uninfected cPLA2(-/-) mice exhibited less killing of C. albicans in vitro than cells from cPLA2(+/+) mice. In addition alveolar macrophages from cPLA2(-/-) mice isolated 6h after instillation of GFP-C. albicans contained fewer internalized fungi than cPLA2(+/+) macrophages.
Example Output:
Does cytosolic phospholipase A2 contribute to innate immune defense against Candida albicans lung infection?
