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 Q]: Context: To identify molecular features associated with clinico-pathological parameters in renal cell cancer.', 'Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging was employed for a kidney cancer tissue microarray containing tissue samples from 789 patients for which clinical follow-up data were available.', 'A comparison of mass spectrometric signals with clinico-pathological features revealed significant differences between papillary and clear cell renal cell cancer. Within the subgroup of clear cell RCC, statistical associations with tumor stage (seven signals, p<0.01 each), Fuhrman grade (seven signals, p<0.0001 each), and presence of lymph node metastases (10 signals, p<0.01 each) were found. In addition, the presence of one signal was significantly linked to shortened patient survival (p=0.0198).\Question: Does mALDI imaging on tissue microarrays identify molecular features associated with renal cell cancer phenotype?
[EX A]: Our data pinpoint towards various molecules with potential relevance in renal cell cancer. They also demonstrate that the combination of the MALDI mass spectrometry imaging and large-scale tissue microarray platforms represents a powerful approach to identify clinically-relevant molecular cancer features.

[EX Q]: Context: The purpose of this study was to examine the effectiveness of ankle bracing and taping in preventing recurrencess of ankle sprains, specifically in female athletes.', "Varsity soccer players' medical records over a five-year period were retrospectively reviewed at a Division III women's college. Data were extracted regarding any history of ankle sprain(s), type of intervention used as prophylaxis after the ankle sprain, number of exposures, and any incidence of recurrence.", 'All collegiate varsity soccer players who had suffered a previous sprain to either one or both ankles (38 players) were identified as subjects.', 'Each previously injured ankle (n = 56) was considered as a case for the analysis. Ankles that had a previous sprain received one of four interventions: 1) a canvas, laced ankle brace (n = 19), 2) taping (n = 12), 3) a combination of taping and ankle bracing (n = 8), or 4) no treatment (n = 17).', 'The four intervention groups had a total of 1717 practice exposures and 650 competitive game exposures; exposures did not differ among the 4 groups. Ankle sprain recurrence frequency was 0%, 25%, 25%, and 35% for the braced, taped, combination, and untreated groups, respectively. The recurrence incidence for the braced group was significantly lower than that of the other three groups. The ankle sprain recurrence frequency did not differ among the taped, combination, and no treatment groups.\Question: Does ankle brace effectively reduce recurrence of ankle sprains in female soccer players?
[EX A]: We suggest that prophylactic ankle bracing is effective in reducing the incidence of ankle sprains in female soccer players with a previous history of ankle sprains.

[EX Q]: Context: Serum elevations of interleukin-6 (IL-6) correlate with multiple organ dysfunction syndrome and mortality in critically injured trauma patients. Data from rodent models of controlled hemorrhage suggest that recombinant IL-6 (rIL-6) infusion protects tissue at risk for ischemia-reperfusion injury. Exogenous rIL-6 administered during shock appears to abrogate inflammation, providing a protective rather than a deleterious influence. In an examination of this paradox, the current study aimed to determine whether rIL-6 decreases inflammation in a clinically relevant large animal model of uncontrolled hemorrhagic shock, (UHS), and to investigate the mechanism of protection.', 'Swine were randomized to four groups (8 animals in each): (1) sacrifice, (2) sham (splenectomy followed by hemodilution and cooling to 33 degrees C), (3) rIL-6 infusion (sham plus UHS using grade 5 liver injury with packing and resuscitation plus blinded infusion of rIL-6 [10 mcg/kg]), and (4) placebo (UHS plus blinded vehicle). After 4 hours, blood was sampled, estimated blood loss determined, animals sacrificed, and lung harvested for RNA isolation. Quantitative reverse transcriptase-polymerase chain reaction was used to assess granulocyte colony-stimulating factor (G-CSF), IL-6, and tumor necrosis factor-alpha (TNFalpha) messenger ribonucleic acid (mRNA) levels. Serum levels of IL-6 and TNFalpha were measured by enzyme-linked immunoassay (ELISA).', 'As compared with placebo, IL-6 infusion in UHS did not increase estimated blood loss or white blood cell counts, nor decrease hematocrit or platelet levels. As compared with the sham condition, lung G-CSF mRNA production in UHS plus placebo increased eightfold (*p < 0.05). In contrast, rIL-6 infusion plus UHS blunted G-CSF mRNA levels, which were not significantly higher than sham levels (p = 0.1). Infusion of rIL-6 did not significantly affect endogenous production of either lung IL-6 or mRNA. As determined by ELISA, rIL-6 infusion did not increase final serum levels of IL-6 or TNFalpha over those of sham and placebo conditions.\Question: Does interleukin-6 infusion blunt proinflammatory cytokine production without causing systematic toxicity in a swine model of uncontrolled hemorrhagic shock?
[EX A]:
Exogenous rIL-6 blunts lung mRNA levels of the proinflammatory cytokine G-CSF. The administration of rIL-6 does not increase the local expression of IL-6 nor TNFalpha mRNA in the lung. Additionally, rIL-6 infusion does not appear to cause systemic toxicity.
