In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Ex Input:
Context: Burns cause thermal injury to local tissue and trigger systemic acute inflammatory processes, which may lead to multiple distant organ dysfunction. We investigated the protective effect of dietary whey supplementation on distant organs in a rat model.', 'Forty-eight rats were divided into six groups of eight: groups 1 and 2 were the controls, fed a standard diet and a whey-supplemented diet, respectively; groups 3 and 4 were fed a standard diet and subjected to burn injury; and groups 5 and 6 were fed a whey-supplemented diet and subjected to burn injury. We measured the oxidative stress variables, as well as glutathione in the liver and kidney, and histologically examined skin samples obtained 4 h (groups 3 and 5) and 72 h (groups 4 and 6) after burn injury.', 'Glutathione (GSH) levels remained the same in the liver but were slightly elevated in the kidneys after burn injury in the rats fed a standard diet. Whey supplementation caused a significant increase in hepatic GSH levels 4 h after burn injury. Moreover, there was a significant rebound effect in the liver and kidney GSH levels after 72 h and whey supplementation potentiated this effect. Hepatic and renal lipid peroxide levels were also increased 4 h after burn injury in the rats fed a standard diet. Whey supplementation significantly suppressed the burn-induced increase in hepatic and renal lipid peroxide levels. Histological examination revealed that although whey supplementation resulted in decreased subepidermal inflammation, the indicators of wound healing and collagen deposition were not improved.\Question: Does whey feeding suppress the measurement of oxidative stress in experimental burn injury?

Ex Output:
Whey pretreatment suppressed hepatic and renal oxidative stress measurements after experimental burn injury.


Ex Input:
Context: The expression of growth-associated protein 43 (GAP-43), a marker of axonal growth, in the dorsal root ganglion (DRG) neurons innervating the lumbar intervertebral disc was assessed using the retrograde tracing method and immunohistochemistry.', 'To study whether disc inflammation affects GAP-43 expression in DRG neurons innervating the disc in rats.', 'Persistent inflammation and nerve ingrowth into the inner layer of degenerated discs can be a cause of discogenic pain. Although the presence of GAP-43-expressing nerve fibers in painful discs has been reported, the expression of GAP-43 in DRG neurons innervating the disc has not been studied.', "Seven days after the application of Fluoro-Gold to the L5-L6 disc, 50 microL of saline (n = 10, control group) or complete Freund's adjuvant (n = 10, inflammatory group) was applied to the disc in rats. Ten days after the Fluoro-Gold application, T13-L5 DRGs were double-stained with GAP-43 and either calcitonin gene-related peptide or isolectin B4 (IB4).", 'The percentage of Fluoro-Gold-labeled neurons that were positive for GAP-43 was significantly higher in the inflammatory group (44%) than in the control group (24%, P < 0.001). In both groups, the majority of GAP-43-positive neurons were small and positive for calcitonin gene-related peptide but not IB4.\Question: Does disc inflammation potentially promote axonal regeneration of dorsal root ganglion neurons innervating lumbar intervertebral disc in rats?

Ex Output:
The present results suggest that disc inflammation potentially promotes axonal growth of DRG neurons innervating the disc. In light of the strong correlation between the expression of calcitonin gene-related peptide and nerve growth factor receptor, it is most likely that nerve growth factor-sensitive DRG neurons extend their axons following disc inflammation.


Ex Input:
Context: Apelin-13 (A13) regulates cardiac homeostasis. However, the effects and mechanism of A13 infusion after an acute myocardial injury (AMI) have not been elucidated. This study assesses the restorative effects and mechanism of A13 on the peri-infarct region in murine AMI model.', '51 FVB/N mice (12weeks, 30g) underwent AMI. A week following injury, continuous micro-pump infusion of A13 (0.5μg/g/day) and saline was initiated for 4-week duration. Dual contrast MRI was conducted on weeks 1, 2, 3, and 5, consisting of delayed-enhanced and manganese-enhanced MRI. Four mice in each group were followed for an extended period of 4weeks without further infusion and underwent MRI scans on weeks 7 and 9.', "A13 infusion demonstrated preserved LVEF compared to saline from weeks 1 to 4 (21.9±3.2% to 23.1±1.7%* vs. 23.5±1.7% to 16.9±2.8%, *p=0.02), which persisted up to 9weeks post-MI (+1.4%* vs. -9.4%, *p=0.03). Mechanistically, dual contrast MRI demonstrated significant decrease in the peri-infarct and scar % volume in A13 group from weeks 1 to 4 (15.1 to 7.4% and 34.3 to 25.1%, p=0.02, respectively). This was corroborated by significant increase in 5-ethynyl-2'-deoxyuridine (EdU(+)) cells by A13 vs. saline groups in the peri-infarct region (16.5±3.1% vs. 8.1±1.6%; p=0.04), suggesting active cell mitosis. Finally, significantly enhanced mobilization of CD34(+) cells in the peripheral blood and up-regulation of APJ, fibrotic, and apoptotic genes in the peri-infarct region were found.\Question: Does apelin-13 infusion salvage the peri-infarct region to preserve cardiac function after severe myocardial injury?

Ex Output:

A13 preserves cardiac performance by salvaging the peri-infarct region and may contribute to permanent restoration of the severely injured myocardium.
