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.

Q: Context: The current study was conducted to examine the effect of red pepper supplementation on cholesteryl ester transfer protein (CETP) activity, along with its anti-atherosclerotic effect in cholesterol-fed rabbits.', 'Rabbits were fed a 1% cholesterol diet for 12 weeks, including a 1% red pepper powder supplement.', 'The red pepper supplemented group exhibited significantly lower CETP activity than the control group during the experimental period (P<0.05). The total cholesterol, triglyceride (TG), LDL-C, VLDL-C, and VLDL-TG levels and atherogenic index (AI) were all significantly lower in the red pepper group than in the control group (P<0.05), whereas the HDL-C level was significantly higher in the red pepper group than in the control group during the experimental period (P<0.05). Furthermore, the red pepper supplementation increased the fecal TG excretion (P<0.05). Based on a morphological examination, the red pepper supplemented group exhibited fewer fat droplet deposits than the control group.
Answer: The current results suggest that red pepper attenuates atherosclerosis, plus plasma CETP would appear to be a risk marker of atherosclerosis in cholesterol-fed rabbits.

A: Does red pepper attenuate cholesteryl ester transfer protein activity and atherosclerosis in cholesterol-fed rabbits?

Q: Context: Ischemic preconditioning (IPC) mitigates ischemia-reperfusion (I/R) injury in experimental models. However, the clinical significance of this protection has been unclear and a mortality reduction has not been previously reported in noncardiac models. This study examined the local and remote protection afforded by skeletal muscle IPC and sought to determine the significance of this protection on mortality.', "Mice subjected to 2 h hindlimb ischemia/24 h reperfusion (standard I/R injury) were compared with those undergoing a regimen of two 20-min cycles of IPC followed by standard I/R injury. Local injury was assessed via gastrocnemius histology, and remote injury was evaluated via intestinal histology and pulmonary neutrophil infiltration (n = 7). Mortality was compared in parallel groups for 1 week (n = 6). Groups were analyzed using an unpaired Student's t-test for gastrocnemius and pulmonary injury, and a Mann-Whitney rank sum test for intestinal injury. Mortality differences were interpreted through a hazard ratio.", 'Significant protection was observed in preconditioned animals. There was a 35% local injury reduction in skeletal muscle (71.2% versus 46.0%, P < 0.01), a 50% reduction in remote intestinal injury (2.3 versus 1.1, P < 0.01), and a 43% reduction in remote pulmonary injury (14.9 versus 8.5, P < 0.01) compared with standard injury controls. Preconditioned animals were also significantly protected from mortality, demonstrating a 66.7% survival at 1 wk compared with 0% survival after standard injury alone (hazard ratio 0.20, 95% CI: 0.02-0.59).
Answer: We have developed a murine model of IPC that demonstrates local and remote protection against I/R injury, and exhibits significant mortality reduction. This model demonstrates the powerful effect of IPC on local and remote tissues and will facilitate further study of potential mechanisms and therapies.

A: Does ischemic preconditioning of skeletal muscle mitigate remote injury and mortality?

Q: Context: Lung transplantation is severely limited by an inadequate supply of lungs from brain-dead donors. A potential solution is use of lungs from non-heart-beating donors (NHBDs) with retrieval at intervals after circulatory arrest and death. A warm ischemic period with concomitant reperfusion injury is a major limiting factor in the transplantation of lungs retrieved from NHBDs. We hypothesized that the administration of the nitric oxide-donor nitroglycerin to lungs from NHBDs would reduce ischemia-reperfusion injury by activation of guanylate cyclase to form guanosine 3',5'-cyclic monophosphate (cGMP).", "An in situ isolated perfused rat lung model was used. Lungs were retrieved from rats at varying intervals after circulatory arrest and death. Lungs were either ventilated with O(2) in situ or not ventilated. Lungs were reperfused at intervals after death with Earle's solution with or without nitroglycerin (0.1 mg/ml). Lung ischemia-reperfusion injury was assessed by capillary filtration coefficient, wet-to-dry lung weight ratio, and pulmonary hemodynamics. Tissue levels of adenine nucleotides and cGMP concentrations were measured by high-performance liquid chromatography and enzyme immunoassay, respectively.", 'Reperfusion with nitroglycerin decreased capillary filtration coefficient compared with reperfusion without nitroglycerin at all post-mortem ischemic times, irrespective of pre-harvest ventilation. cGMP levels increased significantly with nitroglycerin-reperfusion and attenuated decreases in high-energy adenine nucleotides.
Answer: Reperfusion of lungs with nitroglycerin may facilitate safe lung transplantation from NHBDs by reducing capillary leak after reperfusion.

A:
Does nitroglycerin reperfusion reduce ischemia-reperfusion injury in non-heart-beating donor lungs?
