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: Recently we have shown that the imunoglobulins G from blood serum of some multiple sclerosis patients are capable of cleaving histone H1.', 'To check whether histone H1-hydrolyzing abzymes could be detected not only in blood plasma of autoimmune patients, but also during cancer development, particularly during the onset of multiple myeloma.', "Immunoglobulines were isolated from blood serum of multiple myeloma patients (n = 11) by precipitation with 50% ammonium sulfate and tested for proteolytic activity toward linker and core calf thymus histones. Antibody preparations able to cleaved histone H1 were subjected to affinity chromatography on histone H1-Sepharose with following analysis of chromatographic fractions' protease activity. To prove that antibody molecules are responsible for hydrolysis of histone H1, gel filtration at acidic pH with subsequent examination of protease activity of chromatographic fractions (pH-shock analysis) was used.", 'It was found that 3 of 11 antibody preparations are capable of hydrolyzing calf thymus histone H1 but not core histones. It was shown that histone H1-hydrolysing activity of 2 proteolytically active antibody preparations is associated with IgGs that possess affinity towards histone H1. pH-shock analysis proved that protease activity towards histone H1 is intrinsic property of IgG molecules.

A: Are blood serum immunoglobulins of patients with multiple myeloma capable of hydrolysing histone H1?

Q: Surgical site infections (SSIs) after colectomy for colon cancer (CC), Crohn's disease (CD), and diverticulitis (DD) significantly impact both the immediate postoperative course and long-term disease-specific outcomes. We aim to profile the effect of diagnosis on SSI after segmental colectomy using the National Surgical Quality Improvement Program (NSQIP) data set.", "NSQIP data from 2006 to 2011 were investigated, and segmental colectomy procedures performed for the diagnoses of Crohn's disease, DD, and colon malignancy were included. SSI complications were compared by diagnosis using univariate and multivariate analysis.", 'We included 35,557 colectomy cases in the analysis. CD had the highest rate of postoperative SSI (17 vs. 13% DD vs. 10% CC; p\u2009<\u20090.001). Using CC as the comparison group and controlling for multiple variables, the multivariate analysis showed that the CD group had an increased risk for acquiring at least one SSI (odds ratio (OR)\u2009=\u20091.38, p\u2009≤\u20090.001), deep incisional SSI (OR\u2009=\u20091.85, p\u2009=\u20090.03), and organ space SSI (OR\u2009=\u20091.51, p\u2009=\u20090.02).

A: Is crohn 's disease but not diverticulitis an independent risk factor for surgical site infections in colectomy?

Q: In recent years acute rejection has decreased to 10% to 20%. Therefore it is necessary to look for new endpoints in renal transplantation. Serum creatinine and changes in creatinine have been reported to be powerful predictors of long-term kidney transplant survival. Chronic renal allograft nephropathy is the primary cause of long-term graft failure but may appear at any stage in the evolution.', 'Data from 315 patients receiving cadaver donor renal transplants between February 1987 and March 2001 that functioned for 1 year were examined for the influence of demographic characteristics and transplant variables. Creatinine clearance was estimated using the Cockroft-Gault formula. Survival was assessed with the actuarial method. The multivariate analyses were performed using Cox proportional hazard models.', 'The 10-year graft survival showed a relative risk of 2.5 in the univariate analysis when there was more than 10% decrease in renal function at 3 months compared with nadir values. When the decrease was more than 25% of creatinine clearance at the third month, during the evolution and serum creatinine at 3 months introduced in the multivariate model, the latter was not significant, while the other variables had a RR of 4.4 and 10, respectively.

A:
Is evolution of the renal function a better predictor of long-term survival than serum creatinine?
