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]: Conflicting results have been reported regarding the predicative roles of alloreactive natural killer (NK) cells on the outcomes of transplantation in leukaemia patients.', 'We prospectively analysed the human leukocyte antigen (HLA) typing of donor-recipient pairs and the KIR typing of the donors in 97 CML patients to address the predictive roles of NK cells in relapse undergoing T-cell-replete haploidentical transplantation.', "Patients with class I ligands for the donor-inhibitory KIR gene exhibited decreased molecular and haematologic relapse rates (P=0.003 and P=0.015, respectively). There was a significantly reduced risk of molecular and haematologic relapse in patients with HLA-C1C2 or C2C2 who accepted donors with KIR2DS1 or in patients with HLA-Bw4 who accepted donors with KIR3DS1 ('recipient with relevant KIR ligand for donor-activating KIR', n=25), compared with the remaining transplants (n=72, P=0.009 and P=0.009, respectively). In addition, the presence of class I ligand in the recipients of donor-activating KIR contributed to a decreased relapse rate in patients lacking class I ligand in the recipient of donor-inhibitory KIR (P=0.04 and P=0.03, respectively).

[EX Q]: To analyze the expression of HMOX1 and miR-122 in liver biopsy samples obtained from HCV mono-and HIV/HCV co-infected patients in relation to selected clinical parameters, histological examination and IL-28B polymorphism as well as to determine whether HMOX1 expression is dependent on Bach-1.', 'The study group consisted of 90 patients with CHC: 69 with HCV mono and 21 with HIV/HCV co-infection. RT-PCR was used in the analysis of HMOX1, Bach-1 and miR-122 expression in liver biopsy samples and in the assessment of IL-28B single-nucleotide polymorphism C/T (rs12979860) in the blood. Moreover in liver biopsy samples an analysis of HO-1 and Bach-1 protein level by Western Blot was performed.', "HCV mono-infected patients, with lower grading score (G<2) and higher HCV viral load (>600000 IU/mL) demonstrated higher expression of HMOX1. In patients with HIV/HCV co-infection, the expression of HMOX1 was lower in patients with lower lymphocyte CD4 count and higher HIV viral load. IL28B polymorphism did not affect the expression of either HMOX1 or miR-122. Higher HMOX1 expression correlated with higher expression of Bach-1 (Spearman's ρ\u200a=\u200a0.586, p\u200a=\u200a0.000001) and miR-122 (Spearman's ρ\u200a=\u200a0.270, p\u200a=\u200a0.014059).

[EX Q]: We questioned whether infection with murine gammaherpesvirus 68 (HV-68) might exacerbate inflammatory bowel disease using mice deficient in IL-10 (IL-10-/-) as a model of developing colitis.', 'Groups of C57BL/6 mice and IL-10-/- mice were mock-treated or infected with HV-68. Two months following infection, mice were euthanized and a variety of parameters were measured to quantify the extent of inflammation and the presence of virus. Measurements included survival, body weight, splenomegaly, colonic disease scores, liver histopathology, viable bacteria in the liver, and splenic viral burden.', 'IL-10-/- mice infected with HV-68 displayed reduced survival, lower body weights, increased splenomegaly, exacerbated colonic disease scores, increased numbers of viable bacteria in the liver, and increased leukocyte liver infiltration when compared to mock-treated IL-10-/- mice or HV-68 infected C57BL/6 mice. Surprisingly, levels of infectious or latent virus were not significantly different between the groups of mice exposed to HV-68.
