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.

Example Input: Increased placental growth secondary to reduced apoptosis may contribute to the development of macrosomia in GDM pregnancies. We hypothesize that reduced apoptosis in GDM placentas is caused by dysregulation of apoptosis related genes from death receptors or mitochondrial pathway or both to enhance placental growth in GDM pregnancies.', 'Newborn and placental weights from women with no pregnancy complications (controls; N=5), or with GDM (N=5) were recorded. Placental villi from both groups were either fixed for TUNEL assay, or snap frozen for gene expression analysis by apoptosis PCR microarrays and qPCR.', 'Maternal, placental and newborn weights were significantly higher in the GDM group vs. Controls. Apoptotic index of placentas from the GDM group was markedly lower than the Controls. At a significant threshold of 1.5, seven genes (BCL10, BIRC6, BIRC7, CASP5, CASP8P2, CFLAR, and FAS) were down regulated, and 13 genes (BCL2, BCL2L1, BCL2L11, CASP4, DAPK1, IκBκE, MCL1, NFκBIZ, NOD1, PEA15, TNF, TNFRSF25, and XIAP) were unregulated in the GDM placentas. qPCR confirmed the consistency of the PCR microarray. Using Western blotting we found significantly decreased placental pro-apoptotic FAS receptor and FAS ligand (FASL), and increased mitochondrial anti-apoptotic BCL2 post GDM insult. Notably, caspase-3, which plays a central role in the execution-phase of apoptosis, and its substrate poly (ADP-ribose) polymerase (PARP) were significantly down regulated in GDM placentas, as compared to non-diabetic Control placentas.
Example Output: Does gestational diabetes mellitus alter apoptotic and inflammatory gene expression of trophobasts from human term placenta?

Example Input: Many patients with coronary heart disease (CHD) are not managed adequately, and we often fail to reach treatment targets.', 'To investigate if knowledge of risk factors for CHD, measured by a questionnaire, would show any relation to advice to compliance to lifestyle changes to attain treatment goals and adherence to drug therapy.', 'Men and women <71 years who had had a cardiac event were screened consecutively (509) from the medical records. Responders (392) were interviewed, examined and received a questionnaire. Three hundred and forty-seven patients answered the questionnaire regarding their general knowledge of risk factors for CHD, compliance to lifestyle changes to attain treatment goals and adherence to drug therapy.', 'There were statistically significant correlations between general knowledge about risk factors for CHD and compliance to certain lifestyle changes: weight, physical activity, stress management, diet, attainment of lipid level goals and the likelihood of taking prescribed blood pressure-lowering drugs. General knowledge of risk factors had no correlation to blood glucose or blood pressure levels nor on smoking habits or treatment patterns for prescribed lipid- and blood glucose-lowering drugs.
Example Output: Does better knowledge improve adherence to lifestyle changes and medication in patients with coronary heart disease?

Example Input: Plasma levels of adrenomedullin, a potent vasodilator peptide, are increased in cirrhotic patients, whereas its role in vascular hyporeactivity in cirrhosis has not been clarified.', 'Adrenomedullin expression was evaluated by radioimmunoassay and reverse-transcription polymerase chain reaction. Vascular reactivity to phenylephrine, alpha-adrenoceptor agonist, was investigated in the aortic rings from control rats and CCl-induced cirrhotic rats with ascites in the presence of the neutralizing antibody against adrenomedullin, human adrenomedullin and/or N-nitro-L-arginine methyl ester, a nitric oxide synthase inhibitor.', 'Plasma adrenomedullin levels were significantly higher in cirrhotic rats than in controls (16.3 +/- 2.9 versus 7.4 +/- 1.7 fmol/mL, P < 0.05) and correlated negatively with systemic arterial pressure (r = -0.62, P < 0.05). Gene expression of adrenomedullin in various organs (liver, kidney, lung) and vessels (portal vein, aorta) was enhanced in cirrhotic rats compared with controls. Neutralizing antibody against adrenomedullin ameliorated the blunted contractile response to phenylephrine in cirrhotic aorta (Rmax: 1.5 +/- 0.1 versus 1.0 +/- 0.1 g/mg tissue, P < 0.05), whereas contraction remained unchanged in control aorta (Rmax: 1.9 +/- 0.2 versus 1.9 +/- 0.2 g/mg tissue). Intravenous infusion of human adrenomedullin induced a reduction of mean arterial pressure together with an increase of serum nitrate levels, which was abolished by neutralizing antibody against adrenomedullin. Human adrenomedullin caused a blunted contractile response to phenylephrine in both control and cirrhotic aortas, which was not observed in the presence of N-nitro-L-arginine methyl ester.
Example Output:
Does adrenomedullin contribute to vascular hyporeactivity in cirrhotic rats with ascites via a release of nitric oxide?
