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.

[Q]: To correlate cerebral cavernous malformations (CCMs) disease aggressiveness with peripheral blood biomarkers hypothesized mechanistically.', 'A prospective case-control study enrolled 43 CCM patients, where 25-(OH) vitamin D, HDL and non-HDL cholesterol, CRP plasma levels and leukocyte ROCK activity were correlated with parameters of disease aggressiveness reflecting chronic and acute domains.', 'Patients with one or more features of chronically aggressive disease (early age at symptom onset, two or more symptomatic bleeds, high lesion burden) had significantly lower 25-(OH) vitamin D and non-HDL cholesterol levels in comparison to patients without these features.
[A]: Do peripheral plasma vitamin D and non-HDL cholesterol reflect the severity of cerebral cavernous malformation disease?


[Q]: Renal ischemia-reperfusion (I/R) injury may occur after renal transplantation, thoracoabdominal aortic surgery, and renal artery interventions.', 'To investigate the therapeutic effects of aprotinin on tissue protection against I/R injury in a rat model. N-acetylcysteine (NAC), a potent antioxidant, was also tested to assess the experimental model.', 'Twenty-four rats were categorized into 3 groups of 8 rats each: those receiving isotonic sodium chloride solution (control group); NAC, 150 mg/kg; and aprotinin, 40,000 KIU/kg. The animals underwent unilateral nephrectomy after 60 minutes of warm ischemia and 60 minutes of reperfusion of the kidney. Malondialdehyde, a lipid peroxidation marker, and antioxidant glutathione levels were measured in the kidney parenchyma. Tissue samples were obtained for histologic analysis.', 'Compared with the control group, the NAC group demonstrated significantly low levels of malondialdehyde (P = .04) and high levels of glutathione (P = .01). At histopathologic analysis, less acute tubular necrosis (ATN) and cellular swelling was noted in the NAC group (P = .002 and P = .005, respectively). In the aprotinin group, histopathologic analysis revealed less tissue damage in terms of ATN (P < .001, cellular swelling (P < .001), and vacuolysis (P = .002). Compared with the NAC group, ATN (P = .01), vacuolysis (P = .04), and congestion (P = .05) were significantly less in the aprotinin group.

[Q]: To investigate whether serum anti-high mobility group box 1 (anti-HMGB1) antibodies are related to the development of skin lesions in systemic lupus erythematosus (SLE).', 'This study involved 21 SLE patients with skin lesions, 18 without skin lesions, and 22 healthy controls. The presence and serum levels of anti-HMGB1-IgG and -IgM were measured by western blot and enzyme-linked immunosorbent assay (ELISA), respectively. HMGB1 expression and serum antibodies deposited in the skin were visualized by immunofluorescence staining.', 'Using western blot analysis, we detected anti-HMGB1-IgG antibodies in 13 out of 21 SLE patients with skin lesions and 11 out of 18 SLE patients without skin lesions (p > 0.05). Serum levels of anti-HMGB1-IgG measured by ELISA were also comparable between the two groups of SLE patients (p > 0.05) but were higher in patients than in healthy controls (p < 0.05). Similar results were found with serum anti-HMGB1-IgM antibodies. HMGB1 accumulated under the stratum corneum in lupus cutaneous lesions without forming immune complexes with IgG or IgM, which were mainly observed along the epidermal-dermal junction. Furthermore, serum anti-HMGB1-IgM was higher in the group of patients with arthritis than in those without arthritis.
