Given a passage, 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.

Question: Expression of CINCs was regulated differentially in lipopolysaccharide-stimulated rat macrophages. We examined whether the expression of CINCs in lipopolysaccharide-stimulated rat macrophages is similarly inhibited by anti-inflammatory drugs.', 'Rat peritoneal macrophages were stimulated by lipopolysaccharide in the presence of anti-inflammatory steroids (dexamethasone, prednisolone and hydrocortisone) or non-steroidal anti-inflammatory drugs (indomethacin and piroxicam). The production and mRNA expression of three types of CINCs were measured using enzyme-linked immunosorbent assay and northern hybridization.', 'Anti-inflammatory steroids; dexamethasone, prednisolone and hydrocortisone, dose-dependently inhibited the production of CINC-1, -2 and -3, whose inhibitory patterns were similar to each other. Furthermore mRNA expression of each CINC was inhibited by dexamethasone in a dose-dependent manner. In contrast, non-steroidal anti-inflammatory drugs, indomethacin and piroxicam were without effect. Expression of each CINC was regulated differently; the production of CINC-1 reached a maximum at 12 h and then slightly decreased after lipopolysaccharide stimulation, whereas that of CINC-2 and CINC-3 increased up to 24 h. Dexamethasone inhibited the CINCs production and mRNA expression at 9 h after lipopolysaccharide stimulation.

Answer: Is the expression of three types of CINCs by lipopolysaccharide-stimulated rat macrophages inhibited similarly by anti-inflammatory steroids?

Question: Enhanced activation of the mineralocorticoid receptors (MRs) in cardiovascular tissues increases oxidative stress, maladaptive immune responses, and inflammation with associated functional vascular abnormalities. We previously demonstrated that consumption of a Western diet (WD) for 16 weeks results in aortic stiffening, and that these abnormalities were prevented by systemic MR blockade in female mice. However, the cell-specific role of endothelial cell MR (ECMR) in these maladaptive vascular effects has not been explored.', 'We hypothesized that specific deletion of the ECMR would prevent WD-induced increases in endothelial sodium channel activation, reductions in bioavailable nitric oxide, increased vascular remodeling, and associated increases in vascular stiffness in females.', 'Four-week-old female ECMR knockout and wild-type mice were fed either mouse chow or WD for 16 weeks. WD feeding resulted in aortic stiffness and endothelial dysfunction as determined in vivo by pulse wave velocity and ex vivo by atomic force microscopy, and wire and pressure myography. The WD-induced aortic stiffness was associated with enhanced endothelial sodium channel activation, attenuated endothelial nitric oxide synthase activation, increased oxidative stress, a proinflammatory immune response and fibrosis. Conversely, cell-specific ECMR deficiency prevented WD-induced aortic fibrosis and stiffness in conjunction with reductions in endothelial sodium channel activation, oxidative stress and macrophage proinflammatory polarization, restoration of endothelial nitric oxide synthase activation.

Answer: Does endothelial Mineralocorticoid Receptor mediate Diet-Induced Aortic Stiffness in Females?

Question: Chagas heart disease (CHD) patients may have a reduced functional capacity (FC). Field tests, as the Incremental Shuttle Walk Test (ISWT), can estimate peak oxygen uptake (VO2 peak). However, the relationship between the ISWT and the Cardiopulmonary Exercise Testing (CPET), the gold standard in the assessment of FC, is not well established in CHD patients.', 'This study aimed to evaluate the FC of CHD patients by ISWT with direct measurement of VO2 peak and to compare these findings with data obtained from CPET. A secondary goal was to derive a regression equation to calculate the VO2 peak by ISWT.', 'Cross-sectional and correlative study.', 'Research laboratory setting.', 'Thirty-two CHD patients (58.89.0 years, 81.3% women) participated in this study.', 'Eligible patients underwent clinical evaluation, echocardiography, CPET by ramp protocol and ISWT according to current guidelines.', 'The distance walked in ISWT showed a positive correlation with VO2 peak from CPET and ISWT (r=0.456, P=0.009 and r=0.869, P<0.001, respectively). In the agreement analysis, the values of the differences between VO2 peak from CPET and ISWT showed absence of bias (mean bias 95% CI and mean -1.295.09 mL.kg.min). Based in real values of VO2 obtained from ISWT, one equation including sex, functional class and distance walked was provided to predict the VO2 values in this test.

Answer:
