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.

[EX 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.

[EX Q]: For patients receiving endoscopic submucosal dissection (ESD), there is urgent need pertaining to the prevention of postoperative bleeding. We conducted a retrospective propensity score-matched study that evaluated whether pre-ESD gastric lavage prevents postoperative bleeding after ESD for gastric neoplasms.', 'From September 2002 to October 2015, the 760 consecutive patients receiving ESD for gastric neoplasm were enrolled and data regarding them were retrospectively analyzed. All patients received conventional preventive treatment against delayed bleeding after ESD, including the administration of proton pump inhibitor and preventive coagulation of visible vessels, at the end of the ESD procedure.', 'Pre-ESD risk factors for postoperative bleeding included tumor size and no gastric lavage. Using multivariate analysis tumor size >2.0 cm (HR 2.90, 95% CI 1.65-5.10, p = 0.0002) and no gastric lavage (HR 3.20, 95% CI 1.13-9.11, p = 0.029) were found to be independent risk factors. Next, we evaluated the effect of gastric lavage on the prevention of post-ESD bleeding using a propensity score-matching method. A total of 284 subjects (142 per group) were selected. Adjusted odds ratio of gastric lavage for post-ESD bleeding was 0.25 (95% CI 0.071-0.886, p = 0.032).

[EX Q]: Expression of truncated G-CSFR forms in patients with SCN/AML induces hyperproliferation and prolonged cell survival. Previously, we showed that ligand internalization is delayed and degradation of truncated G-CSFR forms is defective in patients with SCN/AML.', 'In this study, we investigated the potential roles of dileucine and tyrosine-based motifs within the cytoplasmic domain of the G-CSFR in modulating ligand/receptor internalization. Using standard binding assays with radiolabeled ligand and COS-7 cells, substitutions in the dileucine motif or deletion of tyrosine residues in the G-CSFR did not alter internalization. Attachment of the transferrin receptor YTRF internalization motif to a truncated G-CSFR form from a patient with SCN/AML corrected defective internalization, but not receptor degradation suggesting that receptor internalization and degradation occur independently via distinct domains and/or processes.
