TASK DEFINITION: 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.
PROBLEM: Menopausal reduction in estrogen causes increased adipose accumulation, leading many to turn to dietary supplements to prevent and treat such changes. Enhanced adipose mobilization stimulated by some supplements can increase the risk of non-alcoholic fatty liver disease (NAFLD). Cytoprotective and anti-obesity compounds may prevent the lipotoxicity associated with mobilization.', 'A phytochemical blend was tested in aged, ovariectomized rats. Rats were given the AIN-93M basal diet or a diet containing varying doses of phytochemicals with 2.4 IU/g vitamin D [diet 1: 1000 mg/kg genistein (G); diet 2: 500 mg/kg (G), 200 mg/kg resveratrol (R), and 1000 mg/kg quercetin (Q); diet 3: 1000 mg/kg (G), 400 mg/kg (R), and 2000 mg/kg (Q)].', 'Serum free fatty acids and hepatic triglycerides were elevated with diets 2 and 3. Despite this increase, the phytochemical blends did not increase apoptotic, cell repair, or remodeling gene expression. The highest phytochemical dose prevented increases in serum alanine aminotransferase.

SOLUTION: Does a dietary phytochemical blend prevent liver damage associated with adipose tissue mobilization in ovariectomized rats?

PROBLEM: Chronic lymphocytic leukemia (CLL) is an incurable disease with a highly variable clinical course. IgV(H) mutational status, chromosomal aberrations, CD38 expression and ZAP-70 expression are prognostic markers in CLL, however, they are not exclusively confined to this disease. We recently identified a novel CLL-specific gene (CLL upregulated gene1, CLLU1) that is exclusively upregulated in CLL cells. Here we describe our evaluation of the prognostic significance of CLLU1 in CLL.', 'A cohort of 59 previously untreated CLL patients was studied. We determined the expression levels of two CLLU1 transcripts, cDNA1 and CDS, by quantitative RT-PCR. The relation between CLLU1 expression and time to therapy, overall survival and presence or absence of ZAP-70, CD38, chromosomal aberrations or IgV(H) mutations in the 59 patients was analyzed.', 'Analyzed as a continuous, quantitative parameter CLLU1 levels significantly predicted time from diagnosis to initiation of therapy (P < or = 0.0003) Analyzed as a categorical parameter, by segregation of the patients into groups with cDNA1 or CDS expression above or below the median, the CLLU1 levels significantly predicted time from diagnosis to initiation of therapy (P = 0.001) and predicted overall survival with borderline significance (P < or = 0.05). Patient stratification according to clinical stage, cytogenetics, IgV(H) mutational status, ZAP-70 and CD38, demonstrated significantly increased CLLU1 expression in all investigated CLL poor risk groups. CLLU1 expression levels contributed additional prognostic information to ZAP-70-positive patients.

SOLUTION: Do cLLU1 expression levels predict time to initiation of therapy and overall survival in chronic lymphocytic leukemia?

PROBLEM: Although successful cochlear implantation of patients with deafness following meningitis is expected, long-term stability of electrical current requirements has not been systematically evaluated. This study evaluated changes in programming for patients deafened by bacterial meningitis and stability of auditory performance over time.', 'In this retrospective descriptive study, cochlear implant (CI) stimulation mode and performance of 14 patients deafened by meningitis were compared with those of an age-matched control group of patients deafened by other causes.', 'There were no significant differences in mean performance between the meningitis group and control group (P > 0.05). However, the postmeningitis group required progressively higher stimulation levels and higher programming modes over time as compared to the control group.

SOLUTION:
Do changes in programming over time in postmeningitis cochlear implant users?
