Given a passage, 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.

Humans can easily restore a speech signal that is temporally masked by an interfering sound (e.g., a cough masking parts of a word in a conversation), and listeners have the illusion that the speech continues through the interfering sound. This perceptual restoration for human speech is affected by prior experience. Here we provide evidence for perceptual restoration in complex vocalizations of a songbird that are acquired by vocal learning in a similar way as humans learn their language.', "European starlings were trained in a same/different paradigm to report salient differences between successive sounds. The birds' response latency for discriminating between a stimulus pair is an indicator for the salience of the difference, and these latencies can be used to evaluate perceptual distances using multi-dimensional scaling. For familiar motifs the birds showed a large perceptual distance if discriminating between song motifs that were muted for brief time periods and complete motifs. If the muted periods were filled with noise, the perceptual distance was reduced. For unfamiliar motifs no such difference was observed.
Does stimulus familiarity affect perceptual restoration in the European starling ( Sturnus vulgaris )?

Various pathways involved in the pathogenesis of sJIA have been identified through gene expression profiling in peripheral blood mononuclear cells (PBMC), but not in neutrophils. Since neutrophils are important in tissue damage during inflammation, and are elevated as part of the acute phase response, we hypothesised that neutrophil pathways could also be important in the pathogenesis of sJIA. We therefore studied the gene profile in both PBMC and neutrophils of sJIA patients treated with tocilizumab.', 'We studied the transcriptomes of peripheral blood mononuclear cells (PBMC) and neutrophils from eight paired samples obtained from 4 sJIA patients taken before and after treatment, selected on the basis that they achieved ACR90 responses within 12 weeks of therapy initiation with tocilizumab. RNA was extracted and gene expression profiling was performed using Affymetrix GeneChip Human Genome U133 Plus 2.0 microarray platform. A longitudinal analysis using paired t-test (p<0.05 and FC1.5) was applied to identify differentially expressed genes (DEGs) between the two time points followed by ingenuity pathway analysis. Gene Set Enrichment Analysis (GSEA) and quantitative real-time PCR were then performed to verify the microarray results.', 'Gene ontology analysis in neutrophils revealed that response to tocilizumab significantly altered genes regulating mitochondrial dysfunction and oxidative stress (p=4.6E-05). This was independently verified with GSEA, by identifying a set of oxidative genes whose expression correlated with response to tocilizumab. In PBMC, treatment of sJIA with tocilizumab appeared to affect genes in Oncostatin M signalling and B cell pathways.
Are mitochondrial and oxidative stress genes differentially expressed in neutrophils of sJIA patients treated with tocilizumab : a pilot microarray study?

Haemophilus species are a common cause of community-acquired pneumonia; however, their significance in posttraumatic pneumonia is unclear.', 'Case series.', 'University hospital, level I trauma center.', 'Two hundred fifty-seven consecutive patients with blunt and penetrating trauma treated for pneumonia.', 'Length of stay in the intensive care unit, duration of ventilatory support, rate of recurrent or persistent pneumonia, and mortality.', 'Ninety-six (37%) of 257 patients treated for pneumonia had a Haemophilus species isolated on sputum culture. Of these 96 patients, 49 (51%) had only Haemophilus species, while 33 (34%) had associated gram-positive organisms and 14 (15%) had gram-negative organisms. Seventeen pure cultures (29%) and seven mixed cultures (15%) (P < .05) were beta-lactamase-positive trains. Compared with patients who had pneumonia caused by other bacteria, patients with Haemophilus species were younger (mean +/- SE, 35 +/- 1.7 vs 42 +/- 1.6 years; P < .05) and more severely injured (Injury Severity Score, 20.7 +/- 1.1 vs 17.5 +/- 0.9; P < .05). There were no differences in any outcome variables between the two groups. Only one (1%) of 96 patients had persistent Haemophilus species on sputum cultures after 7 days of treatment.
Is haemophilus pneumonia a common cause of early pulmonary dysfunction following trauma?
