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.

Q: Inadequate response of the innate immune system to bacterial antigens present in the intestinal flora may play a role in the development of necrotizing enterocolitis (NEC). Pattern recognition receptors such as CD14, toll-like receptor (TLR) 4, and caspase-recruitment domain (CARD) 15 bind bacterial lipopolysaccharide and peptidoglycan, and their activation leads to production of inflammatory cytokines. Our aim was to evaluate whether single nucleotide polymorphisms (SNPs) of CD14, TLR4, and CARD15 are associated with the risk of NEC in very low birth weight (VLBW) infants.', 'We determined the CD14 C-260T, TLR4 A +896G, C +1196T, and CARD15 G +2722C, C +2104T, 3020insC functional SNPs in dried blood samples from 118 VLBW infants (of those, 41 developed NEC) and from 146 healthy term newborns using polymerase chain reaction and restriction fragment length polymorphism methods. We tested the association between genotype and risk of NEC.', 'No significant differences were found in the prevalence of CD14 -260T, TLR4 +896G, +1196T, and CARD15 +2722C, +2104T, 3020insC alleles between VLBW infants and healthy term newborns (P = NS). The frequencies of investigated genotypes were similar in infants with and without NEC (P = NS). Furthermore, we did not find any association between genotype and prematurity or sepsis, which are important risk factors of NEC.

A: Are genetic polymorphisms of CD14 , toll-like receptor 4 , and caspase-recruitment domain 15 associated with necrotizing enterocolitis in very low birth weight infants?

Q: To ascertain whether inoculation of lipopolysaccharide (LPS) into the mouse cochlea might induce enhancement of DNA binding activity of NK-kappa B and to establish a positive model of NF-kappa B activation in the cochlea.', 'Two groups of CBA mice were transtympanically injected either with 10 micrograms of LPS or an equal volume of saline. The nuclear proteins of the cochlea were extracted, quantitated and bound with 32P-radiolabeled oligonucleotide probe for NF-kappa B. The bound and free probes were separated by electrophoresis on a 4.5% native polyacrylamide gel. Supershift assays were carried out using the antibodies against NF-kappa B subunit P65 and P50.', 'The radiolabeled probe bound differently to nuclear extracts from the LPS-treated and the saline-treated mouse cochleae, showing that LPS inoculation significantly increased NF-kappa B binding activity. Supershift analysis demonstrated that the enhancement of DNA binding activity was related to both P65 and P50 subunits.

A: Does [ Lipopolysaccharide enhance DNA binding activity of nuclear factor-kappa B in the mouse cochlea ]?

Q: Individuals diagnosed with blood-injury phobia respond to venipuncture with strong psychophysiological responses. We investigated whether disgust sensitivity contributes to the fainting response and is associated with parasympathetic activation, as suggested by previous research.', 'Twenty individuals diagnosed with blood-injury phobia (9 with a history of fainting to the sight of blood, 11 without such a fainting history) and 20 healthy controls were compared. Psychophysiological responses and self-report measures of anxiety, disgust, and embarrassment were monitored during rest, a paced breathing task, and venipuncture. In addition, trait disgust sensitivity and blood-injury fears were assessed.', 'Blood-injury phobics reported enhanced anxiety, disgust, and embarrassment during venipuncture. They also experienced heightened arousal, as indicated by heart rate, respiration rate, and minute ventilation. Blood-injury phobics without a fainting history tended toward higher anxiety and disgust scores. There was no evidence for increased parasympathetic activation in either blood-injury phobic subgroup or of an association of disgust and parasympathetic activation.

A:
Does blood-injury phobia with and without a history of fainting : disgust sensitivity explain the fainting response?
