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.

In rats, oral oleoyl-estrone (OE) decreases food intake and body lipid content. The aim of this study was to determine whether OE treatment affects the energy metabolism of pregnant rats and eventually, of their pups; i.e. changes in normal growth patterns and the onset of obesity after weaning.', 'Pregnant Wistar rats were treated with daily intragastric gavages of OE in 0.2 ml sunflower oil from days 11 to 21 of pregnancy (i.e. 10 nmol oleoyl-estrone/g/day). Control animals received only the vehicle. Plasma and hormone metabolites were determined together with variations in cellularity of adipose tissue.', "Treatment decreased food intake and lowered weight gain during late pregnancy, mainly because of reduced adipose tissue accumulation in different sites. OE-treated pregnant rats' metabolic pattern after delivery was similar to that of controls. Neonates from OE-treated rats weighed the same as those from controls. They also maintained the same growth rate up to weaning, but pups from OE-treated rats slowed their growth rate afterwards, despite only limited differences in metabolite concentrations.
Does treatment of pregnant rats with oleoyl-estrone slow down pup fat deposition after weaning?

Since manganese (Mn) is capable of stimulating the hypothalamic-pituitary unit and advancing female puberty, we assessed the possibility that this element might overcome some of the detrimental effects of prepubertal alcohol (ALC) exposure on the hypothalamic control of pituitary function.', 'Rats received either saline or Mn (10mg/kg) daily by gastric gavage from day 12 to day 31. After weaning, all rats were provided Lab Chow diet ad libitum until day 27 when they began receiving either the Bio Serv control or ALC diet regime. On day 31, the medial basal hypothalamus (MBH) was collected to assess luteinizing hormone-releasing hormone (LHRH) and cyclooxygenase 2 (COX2) protein levels. Release of prostaglandin-E2 (PGE2), LHRH and serum luteinizing hormone (LH) were also assessed. Other animals were not terminated on day 31, but remained in study to assess timing of puberty.', 'Short-term ALC exposure caused elevated hypothalamic LHRH content, suggesting an inhibition in peptide release, resulting in a decrease in LH. Both actions of ALC were reversed by Mn supplementation. COX2 synthesis, as well as PGE2 and LHRH release were suppressed by ALC exposure, but Mn supplementation caused an increase in COX2 synthesis and subsequent PGE2 and LHRH release in the presence of ALC. Mn supplementation also ameliorated the action of ALC to delay puberty.
Does manganese protect against the effects of alcohol on hypothalamic puberty-related hormones?

To determine the rate of persistent tracheocutaneous fistula (TCF) in pediatric patients managed with stomal maturation at the time of the tracheostomy.', 'Retrospective chart analysis of all cases of tracheostomy performed at a tertiary pediatric care center between 2001 and 2011.', 'The use of stomal maturation, number of decannulations, number of persistent TCFs, timing of TCF repair, and the overall mortality were assessed.', 'A total of 264 patients received tracheostomy between 2001 and 2011. Of the total, 173 (66%) underwent stomal maturation. Of those 173 patients, 89 patients (51% of maturation group) underwent planned decannulation. Forty seven (53%) of the 89 decannulated were found to have a persistent TCF in the stomal maturation group. These were diagnosed an average of 1.3 years (range, 4-43 months) after decannulation. Of the 91 patients (34% of the total) who did not undergo stomal maturation, 44 (48% of nonmaturation group) underwent planned decannulation. Twenty of the 44 patients decannulated (45%) were diagnosed with a residual TCF 8 to 28 months later. Both groups achieved similar rates of decannulation (51% maturation vs. 48% non-maturation [P=.80]) and TCF (27% maturation vs. 22% non-maturation [P=.44]). Overall, mortality rates were (32/173) 18% (matured) versus (26/91) 29% (nonmatured). No mortalities were tracheostomy related. The mean (standard deviation) time from operation to TCF closure among those with TCF was 4.0 (1.9) years.
Does stomal maturation increase the rate of tracheocutaneous fistulas?
