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.

Proinflammatory cytokines have the potential to activate the hypothalamo-pituitary-adrenocortical (HPA) axis, and HPA axis hyperactivity is also encountered in depression. Therefore, the induction of depressive symptoms by interferon-alpha (IFN-alpha) may be mediated by changes in the cytokine network and the HPA axis.', 'In 17 hepatitis C patients undergoing IFN-alpha treatment, depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS). In addition, serum cytokine concentrations were measured. Saliva was collected five times over the course of a day in order to assess daily average cortisol (DAC) and awakening response. Assessments were carried out at baseline and six later time points after starting treatment.', 'During treatment, the increases in the MADRS were significantly and positively correlated with soluble interleukin (IL)-2 receptor, tumor necrosis factor alpha (TNF-alpha), and IL-6. There were no significant associations between the DAC or cortisol awakening response with the MADRS score.
Are interferon-alpha-induced depressive symptoms related to changes in the cytokine network but not to cortisol?

Sprague and Tatum (1942) introduced the concepts of general combining ability (GCA) and specific combining ability (SCA) to evaluate the breeding parents and F1 hybrid performance, respectively. Since then, the GCA was widely used in cross breeding for elite parent selection. However, the molecular basis of GCA remains to unknown.', 'We studied the transcriptomes of three varieties and three\xa0F1 hybrids using RNA-Sequencing. Transcriptome sequence analysis revealed that the transcriptome profiles of the F1s were similar to the positive GCA-effect parent. Moreover, the expression levels of most differentially expressed genes (DEGs) were equal to the parent with a positive GCA effect. Analysis of the gene expression patterns of gibberellic acid (GA) and flowering time pathways that determine plant height and flowering time in rice validated the preferential transcriptome expression of the parents with positive GCA effect. Furthermore, H3K36me3 modification bias in the Pseudo-Response Regulators (PRR) gene family was observed in the positive GCA effect parents and demonstrated that the phenotype and transcriptome bias in the positive GCA effect parents have been epigenetically regulated by either global modification or specific signaling pathways in rice.
Is the phenotypic predisposition of the parent in F1 hybrid correlated with transcriptome preference of the positive general combining ability parent?

"Virtual fracture clinics" have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a "top-down" analysis of the cost effectiveness of this virtual fracture clinic pathway.', 'National Health Service financial returns relating to our institution were examined for the time period 2009 to 2014 which spanned the service redesign.', 'The total staffing costs rose by 4% over the time period (from £1 744 933 to £1 811 301) compared with a national increase of 16%. The total outpatient department rate of attendance fell by 15% compared with a national fall of 5%. Had our local costs increased in line with the national average, an excess expenditure of £212 705 would have been required for staffing costs.

Does fracture clinic redesign reduce the cost of outpatient orthopaedic trauma care?
