In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: Mild hypothermia for 72 hours is neuroprotective in newborns with moderate or severe hypoxic-ischemic encephalopathy. A core temperature of 33.5 degrees C might reduce drug clearance leading to potential toxicity. Gentamicin is nephrotoxic and ototoxic at high serum concentrations. No study has investigated the influence of 72 hours of hypothermia on serum gentamicin concentrations (SGCs) in children of any age. We aimed to compare the SGCs in encephalopathic infants who underwent intensive care with therapeutic hypothermia or normothermia.', 'Data were collected retrospectively from 2 NICUs in Bristol, United Kingdom, that offered cooling therapy within clinical trials since 1998. Eligible infants (n = 55) developed grade 2/3 encephalopathy after birth and fulfilled the entry criteria defined in the CoolCap trial. Encephalopathic infants with similar demographic values were either nursed under normothermia or 72 h-hypothermia. Once-daily gentamicin dosage (4-5 mg/kg) was administered, and trough SGC was recorded with corresponding creatinine concentrations. The time and number of omitted drug doses were noted.', 'Mean trough SGC (pre-second dose) and mean plasma creatinine concentrations for both treatment groups were similar (gentamicin: 2.19 +/- 1.7 [hypothermia] and 2.30 +/- 2.0 [normothermia] mg/L; creatinine: 115.6 +/- 42.8 [hypothermia] and 121.0 +/- 45.1 [normothermia] mumol/L). Forty percent of the trough SGCs in both groups were above the recommended trough concentration of 2.0 mg/L. A significant correlation (r(2) = 0.36) was found between high SGCs and impaired renal function assessed by raised plasma creatinine levels regardless of treatment options.\Question: Are serum gentamicin concentrations in encephalopathic infants affected by therapeutic hypothermia?

Output: Our data confirm that impaired renal function is strongly associated with high SGCs. Reduced body temperatures do not affect the clearance of gentamicin.


Input: Consider Input: Context: Allergic asthma is characterized by inflammation and airway remodeling. Bronchial epithelium is considered a key player in coordinating airway wall remodeling. In mild asthma, the epithelium is damaged and fails to proliferate and to repair, whereas in severe asthma, the epithelium is highly proliferative and thicker. This may be due to different regulatory mechanisms. The purpose of our study was to determine the role of miRNAs in regulating proliferation of bronchial epithelial cells obtained from severe asthmatic subjects in comparison with cells obtained from mild asthmatics and healthy controls.', 'Human bronchial epithelial cells (BEC) were isolated by bronchoscopy from bronchial biopsies of healthy donors and patients with mild and severe asthma. MiRNA expression was evaluated using the TaqMan low-density arrays and qRT-PCR. Transfection studies of bronchial epithelial cells were performed to determine the target genes. Cell proliferation was evaluated by BrdU incorporation test.', 'MiR-19a was upregulated in epithelia of severe asthmatic subjects compared with cells from mild asthmatics and healthy controls. Functional studies based on luciferase reporter and Western blot assays suggest that miR-19a enhances cell proliferation of BEC in severe asthma through targeting TGF-β receptor 2 mRNA. Moreover, repressed expression of miR-19a increased SMAD3 phosphorylation through TGF-β receptor 2 signaling and abrogated BEC proliferation.\Question: Does microRNA-19a enhance proliferation of bronchial epithelial cells by targeting TGFβR2 gene in severe asthma?

Output: Our study uncovers a new regulatory pathway involving miR-19a that is critical to the severe phenotype of asthma and indicates that downregulating miR-19a expression could be explored as a potential new therapy to modulate epithelium repair in asthma.


Input: Consider Input: Context: Nitric oxide (NO), an important mediator of the inflammatory response, is involved in several reproductive processes including pregnancy and labor. Uterus, placenta and fetal membranes are significant sources of NO. Presently, there is no information on factors regulating NO production by fetal membranes.', 'Human fetal membranes at term gestation were cultured for 24 hr in the presence of oxytocin. The concentrations of NO metabolites nitrites in culture medium were determined by the Griess reaction. The presence of inducible nitric oxide synthase (iNOS) was determined by reverse transcriptase-polymerase chain reaction and Western blot.', 'Oxytocin increased nitrite release by fetal membranes. Messenger ribonucleic acid iNOS expression was also enhanced by oxytocin. These effects were more marked in tissues obtained after labor than before labor.\Question: Does oxytocin modulate nitric oxide generation by human fetal membranes at term pregnancy?


Output: Oxytocin exerts an overall stimulatory effect on NO release by fetal membranes. This action might be of relevance in the biomolecular processes leading to parturition.
