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.

Input: Consider Input: Ametop gel (4% amethocaine) is a relatively new topical anesthetic that produces anesthesia within 30 to 45 minutes and therefore may be appropriate for use in busy outpatient settings. The objective of this study was to assess the efficacy and safety of 4% amethocaine in reducing the pain of subcutaneous measles-mumps-rubella vaccination in 1-year-old infants.', 'A double-blind, randomized, placebo-controlled trial was conducted in pediatric outpatient clinics.', 'A total of 120 infants participated in the study; 60 were followed up for assessment of antibody titers after 1 month. Either 1 g of amethocaine or placebo was applied for 30 minutes before vaccination. The Modified Behavioral Pain Scale was used to assess pain; the mean (standard deviation) pain scores for the amethocaine group (n = 61) was 1.5 (1.6) versus 2.3 (2.2) for the placebo group (n = 59). The rate of vaccination success (88% and 87%) was not different between treatment groups.

Output: Does topical 4 % amethocaine gel reduce the pain of subcutaneous measles-mumps-rubella vaccination?


Input: Consider Input: A defect in retinal pigment epithelial (RPE) cells may cause dysfunction of the neural retina, so rapid recovery of differentiated RPE cells is required after RPE injury. We investigated the effect of hepatocyte growth factor (HGF) on wound healing in RPE cells.', 'Confluent monolayers of bovine RPE cells were denuded, and the cells were allowed to recover in the presence or absence of HGF. The effect of HGF on RPE cell proliferation was evaluated by a 3-(4;5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulphophenyl)-2H-tetraz olium assay. In a migration assay, mitomycin C was used to inhibit proliferation, and the number of migrated cells was counted. The signaling pathways involved were examined using inhibitors of mitogen-activated protein kinase (MAPK), phosphatidylinositol-3 (PI3) kinase and protein kinase C pathways.', 'At 80 ng/mL, HGF stimulated the wound closure of RPE monolayers and rendered the restituted cells more epithelioid in shape. HGF at 10 ng/mL stimulated RPE cell migration the most, whereas 80 ng/mL of HGF inhibited migration, but stimulated proliferation the most. In particular, PI3 kinase and MAPK inhibitor inhibited PRE cell migration and proliferation, respectively.

Output: Does hepatocyte growth factor stimulate proliferation and migration during wound healing of retinal pigment epithelial cells in vitro?


Input: Consider Input: The goal was to link hypertension and the metabolic syndrome in adulthood directly to blood pressures measured decades earlier for the same individuals as children and to establish criterion values for blood pressure that predict hypertension and the metabolic syndrome later in life.', 'We analyzed serial data for 240 men and 253 women in the Fels Longitudinal Study. We derived age- and gender-specific childhood blood pressures that predict hypertension and the metabolic syndrome in adulthood, and we validated these criterion values in a larger sample.', 'Blood pressure diverged between adults with and without the metabolic syndrome beginning at age 5 for boys and age 8 for girls. The odds ratios for developing hypertension at > or = 30 years of age ranged from 1.1 for 14- to 18-year-old boys to 3.8 for 5- to 7-year-old boys and from 2.7 for 8- to 13-year-old girls to 4.5 for 5- to 7-year-old girls, if their blood pressure exceeded criterion values at a single examination in childhood. The corresponding odds ratios for the metabolic syndrome, with or without hypertension, ranged from 1.2 for 14- to 18-year-old boys to 2.6 for 8- to 13-year-old boys and from 1.5 for 14- to 18-year-old girls to 3.1 for 5- to 7-year-old girls. The relative risk of adult hypertension ranged from 1.5 to 3.8 for boys and from 1.5 to 4.7 for girls, and that of the metabolic syndrome ranged from 1.1 to 1.8 for boys and from 1.2 to 5.6 for girls. These relative risks varied directly with the number of examinations at which systolic blood pressure exceeded criterion values.


Output: Does systolic blood pressure in childhood predict hypertension and metabolic syndrome later in life?
