Given a passage with a context and an answer, 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: Context: We hypothesized that atherosclerosis inhibits NO-mediated endothelium-dependent dilation of coronary arterioles through interaction of ox-LDL with its receptor, LOX-1, through the production of O2y- in endothelial cells.', 'We assessed the role of ox-LDL in endothelial dysfunction in a murine model of atherosclerosis (ApoE KO mice). Coronary arterioles from WT control and ApoE KO mice were isolated and pressurized without flow. Although dilation of vessels to endothelium-independent vasodilator SNP was not altered between ApoE KO and WT mice, dilation to the endothelium-dependent agonist, ACh was reduced in ApoE KO versus WT mice. Impaired vasodilation to ACh in ApoE KO mice is partially restored by NAD(P)H oxidase inhibitor, apocynin or DPI. Messenger RNA expression for NAD(P)H oxidases was higher in ApoE KO mice than that in WT and anti-LOX-1 treated ApoE KO mice. Anti-LOX-1, given in vivo, restored NO-mediated coronary arteriolar dilation in ApoE KO mice, but did not affect the endothelium-dependent vasodilation in controls.
Answer: These results suggest that ox-LDL impairs endothelium-dependent NO-mediated dilation of coronary arterioles by activation of a signaling cascade involving LOX-1 and NAD(P)H oxidase expression.
Example Output: Does anti-LOX-1 rescue endothelial function in coronary arterioles in atherosclerotic ApoE knockout mice?

Example Input: Context: To explore the role of SCF/c-Kit signaling in the invasion of bladder cancer T24 cells.', 'Western blotting was used to detect the expression of c-Kit and PI3K pathway activation stimulated by stem cell factor (SCF) in T24 cells. The invasiveness of T24 cells before and after SCF stimulation and Wortmannin (aspecific PI3K inhibitor) treatment was evaluated using Transwell invasion assay (direct and indirect counting methods).', 'T24 cells expressed c-Kit protein and showed obvious Akt phosphorylation after stimulation with SCF (1 ng/ml) for 24 h. Compared to the control group, SCF stimulation (1 ng/ml) caused a greater number of T24 cells to migrate through the polycarbonate film (P<0.01), and this effect was blocked by the application of Wortmannin before the stimulation.
Answer: SCF/c-Kit signaling promotes the invasiveness of T24 cells, and this effect is mediated by the PI3K pathway.
Example Output: Does [ SCF/c-Kit signaling promote invasion of T24 cells via PI3K pathway ]?

Example Input: Context: Prospective cohort.', 'Elbow stiffness is the most common adverse event after isolated radial head fractures.', 'To assess the effect of coaching on elbow motion during the same office visit in patients with such fractures.', 'We enrolled 49 adult patients with minimally displaced radial head fractures, within 14 days of injury. After diagnosis, we measured demographics, catastrophic thinking, health anxiety, symptoms of depression, upper extremity-specific symptoms and disability, pain, and elbow and wrist motion. The patient was taught to apply an effective stretch in spite of the pain to limit stiffness, and elbow motion was measured again.', 'With the exception of radial deviation and pronation, motion measures improved slightly but significantly on average immediately after coaching. Elbow flexion improved from 79% (110 22) of the uninjured side to 88% (122 18) after coaching (P<.001); elbow extension improved from 71% (29 14) to 78% (22 15) (P=.0012).
Answer: Instruction that stretching exercises are healthy even when painful resulted in immediate improvements in motion. Prospective studies comparing different strategies for coaching patients regarding painful stretches might help clarify the optimal approach.
Example Output:
Does coaching of patients with an isolated minimally displaced fracture of the radial head immediately increase range of motion?
