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.

Context: Magnetic Resonance Imaging (MRI) allows a detailed "in vivo" macroscopic study of the human brain; previously, it has been demonstrated that Fluid Attenuated Inversion Recovery (FLAIR) sequence shows higher signal intensity of cortices belonging to limbic structures.', 'To measure and compare signal intensities (SI) of cytoarchitectonically different cortical regions.', 'In 22 adult subjects, without psychiatric or neurological diseases, FLAIR sequence was performed in coronal slices, perpendicular to the main hippocampal axis. Signal intensity was measured, with a region-of-interest (ROI) function, in 12 different cortical regions. We compared these values and grouped the cortices into five groups: (1) limbic cortices, (2) paralimbic agranular cortices, (3) paralimbic granular cortices, (4) parietal-type neopallium, (5) frontal-type neopallium. A t-test for comparison of paired samples was performed, considering p</=0.05 as statistically significant.', 'We found statistically significant differences amongst the different groups, with the exception of groups 1 and 2, which did not show differences between them. No statistically significant differences were found among cortices belonging to the same group.\Question: Does magnetic resonance imaging identify cytoarchitectonic subtypes of the normal human cerebral cortex?
Structural characteristics of the cerebral cortex cause changes in its signal intensity. Magnetic resonance imaging (FLAIR sequence) allows discrimination of different cytoarchitectonic areas of the human cerebral cortex.

Context: Treatment of difficult asthma with oral corticosteroids (OCS) may suppress the hypothalamic-pituitary-adrenal axis.', 'In this study we have checked if the substitution of OCS with very high doses of ciclesonide may restore the adrenal function without losing the control of the disease.', 'In 5 patients with difficult, uncontrolled asthma despite treatment with OCS, inhaled and systemic glucocorticosteroids were replaced with very high doses of ciclesonide (1600-2400 g/day). The symptoms of asthma and the lung function were assessed at baseline and on the 28(th), 56(th) and 70(th) day of treatment, whereas the levels of cortisol and adrenocorticotropic hormone (ACTH) in the morning were measured at baseline and on the 28(th) and the 56(th) day of treatment.', 'In all patients, the control of asthma symptoms, measured with Asthma Control Test questionnaire, improved from the mean score of 9.4 to 19.8 in 70 days. In 4 subjects force expiratory volume in 1 s improved gradually through the entire study reaching a mean improvement of 585 ml in 70 days. The ACTH levels were normalized in 3 patients after 28 days of observation and in all patients after 56 days. The cortisol level was normalized in 4 patients after 28 days and in another subject after 56 days of treatment with ciclesonide.\Question: Does switching from systemic steroids to ciclesonide restore the hypothalamic pituitary-adrenal axis?
Switching from prednisone to very high doses of ciclesonide normalized the hypothalamic-pituitary adrenal axis function and also improved the disease control and the lung function in these 5 patients with difficult asthma.

Context: Polymorphisms in the LPA gene were associated with coronary artery disease (CAD). However, there are differences in the allelic frequencies, Lp(a) levels, and significant association with CAD according to ethnic groups. In this scenario, the main aim of this study was to assess the influence of the LPA polymorphisms on coronary lesions in Brazilian patients.', '1,394 consecutive patients submitted to coronary angiography to study suggestive CAD and twenty coronary segments were scored. Genotyping for the LPA rs10455872 and rs3798220 polymorphisms were performed by high resolution melting analysis.', 'The frequencies of the rs10455872 G and rs3798220 C variant alleles were 6.4% and 6.2%, respectively. LPA rs10455872 G variant allele was associated with higher odds ratio of having coronary lesions in an adjusted model (OR=2.02, 95% CI=1.10-3.72, p=0.02). Scores of coronary lesions (extension, severity, and Gensini scores) were significantly different among rs10455872 genotype groups. Coronary lesions was not associated with LPA rs3798220 (OR=1.09, 95% CI=0.67-1.76, p=0.73) and scores of coronary lesions were not different among rs3798220 genotypes.\Question: Is lPA rs10455872 polymorphism associated with coronary lesions in Brazilian patients submitted to coronary angiography?
We confirmed the association of the LPA rs10455872 with CAD in a large sample of Brazilian patients. For the LPA rs3798220, our finding is consistent with studies which showed the lack of this genetic association.
