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.

Input: Consider Input: Context: Many trauma patients have been consuming alcohol at the time of injury. Although high concentrations of alcohol are correlated with poor outcome, few studies have examined the effects of low levels of alcohol. We examined the effects of low alcohol exposure after burn injury using a murine model.', 'Three- and 18-month-old mice were given ethanol or saline 30 minutes before a 15% total body surface area burn injury. Twenty-four hours after injury, cellular immune responses, including delayed-type hypersensitivity response and splenocyte proliferation were examined, along with production of interferon-gamma, interleukin (IL)-2, and IL-4.', 'Alcohol administration resulted in a significant increase in interferon-gamma in the aged, but not young, burn-injured mice. Likewise, slight increases in IL-2, IL-4, and the delayed-type hypersensitivity response were observed.
Answer: Low levels of ethanol at the time of injury are associated with partial restoration of immune responses in aged mice.

Output: Is a low blood ethanol level associated with improved cytokine production in aged mice after traumatic injury?

Input: Consider Input: Context: We analyzed the involvement of thromboxane (TX) A2/prostaglandin (PG) H2 (TP) receptor in ischemia-induced neovascularization in mice.', 'Unilateral hindlimb ischemia was induced by right femoral artery ligature in male C57BL/6J mice (n=7 per group). Animals were then treated with or without TP receptor antagonist (S18886, 5 or 10 mg/kg per day; ramatroban, 10 mg/kg per day) or aspirin (30 mg/kg per day) in drinking water for 21 days. Hindlimb ischemia raised plasma level of TXB2, the stable metabolite of TXA2, by 4.7-fold. This increase was blocked by aspirin treatment whereas S18886 (5 or 10 mg/kg per day) had no effect. However, neither S 18886 nor aspirin affected postischemic neovascularization. We next assessed the putative involvement of TXA2 signaling in angiotensin II (Ang II) proangiogenic pathway. Ang II (0.3 mg/kg per day) enhanced TXB2 plasma levels by 2.6-fold over that of control (P<0.01). Ang II-induced TXB2 upregulation was reduced by cotreatment with Ang II type I receptor antagonist (candesartan, 20 mg/kg per day). Angiographic score, capillary number, and foot perfusion were improved by 1.7-, 1.7-, and 1.4-fold, respectively, in Ang II-treated mice compared with controls (P<0.05). Ang II proangiogenic effect was associated with a 1.6-fold increase in VEGF-A protein content (P<0.05) and a 1.4-fold increase in the number of Mac-3-positive cells (ie, macrophages) in ischemic areas (P<0.05). Interestingly, treatments with TP receptor antagonists or aspirin hampered the proangiogenic effects of Ang II.
Answer: Endogenous activation of TXA2 receptor by eicosanoids did not modulate spontaneous neovascularization in the setting of ischemia. Conversely, TXA2 signaling is involved in Ang II-induced AT1-dependent vessel growth.

Output: Does thromboxane A2/prostaglandin H2 receptor activation mediate angiotensin II-induced postischemic neovascularization?

Input: Consider Input: Context: Treatment of difficult asthma with oral corticosteroids (OCS) may suppress the hypothalamic-pituitary-adrenal axis.', 'In this study we have checked if the substitution of OCS with very high doses of ciclesonide may restore the adrenal function without losing the control of the disease.', 'In 5 patients with difficult, uncontrolled asthma despite treatment with OCS, inhaled and systemic glucocorticosteroids were replaced with very high doses of ciclesonide (1600-2400 g/day). The symptoms of asthma and the lung function were assessed at baseline and on the 28(th), 56(th) and 70(th) day of treatment, whereas the levels of cortisol and adrenocorticotropic hormone (ACTH) in the morning were measured at baseline and on the 28(th) and the 56(th) day of treatment.', 'In all patients, the control of asthma symptoms, measured with Asthma Control Test questionnaire, improved from the mean score of 9.4 to 19.8 in 70 days. In 4 subjects force expiratory volume in 1 s improved gradually through the entire study reaching a mean improvement of 585 ml in 70 days. The ACTH levels were normalized in 3 patients after 28 days of observation and in all patients after 56 days. The cortisol level was normalized in 4 patients after 28 days and in another subject after 56 days of treatment with ciclesonide.
Answer: Switching from prednisone to very high doses of ciclesonide normalized the hypothalamic-pituitary adrenal axis function and also improved the disease control and the lung function in these 5 patients with difficult asthma.
Output: Does switching from systemic steroids to ciclesonide restore the hypothalamic pituitary-adrenal axis?
