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: To determine whether follicle curetting at the time of oocyte retrieval increases oocyte yield.', 'Retrospective review of all patients who underwent oocyte retrieval from July 1, 2003 to June 30, 2005.', 'Number of oocytes retrieved.', 'retrieval time, number of cryopreserved embryos, pregnancy rates, and incidence of ovarian hyperstimulation syndrome.', 'There were no differences in patient demographics, antral follicle count, cycle stimulation characteristics, fertilization rates, embryo quantity or quality, embryo cryopreservation rates, clinical pregnancy rates, live birth rates, or ovarian hyperstimulation syndrome between the groups. Retrievals that utilized curetting took three minutes longer. Follicle curetting significantly increased the number of oocytes retrieved, 13.9 +/- 0.6 compared to 11.4 +/- 0.6 oocytes without curetting (P = 0.003). The quantity of mature oocytes was also increased with curetting (10.3 +/- 0.5 versus 8.4 +/- 0.5, P = 0.006).\Question: Does follicle curetting at the time of oocyte retrieval increase the oocyte yield?

Ex Output:
This study demonstrated that follicle curetting significantly increased oocyte yield. While it did not increase live birth rates, this increase in oocyte yield should lead to increased numbers of embryos for selection at transfer and increased embryos for cryopreservation.


Ex Input:
Context: Interleukin-6 (IL-6) is a vital inflammatory factor in the peritoneal cavity of peritoneal dialysis (PD) patients. Because intraperitoneal inflammation is closely associated with angiogenesis, we sought to explore the effect of IL-6 on vascular endothelial growth factor (VEGF) synthesis and its transduction pathway in mesothelial cells.', 'Human mesothelial cells (Met-5A) were incubated with different concentrations of glucose and mannitol, and the effect of glucose and mannitol on the expression of IL-6 was determined. Then, the cells were stimulated by IL-6 with or without two soluble receptors of IL-6 (sIL-6R or sgp130), and VEGF synthesis was detected. Finally, the cells were incubated with IL-6/sIL-6R combined with or without the inhibitor of Janus kinases (JAK) AG490. The phosphorylation of the signal transducer and activator of transcription 3 (STAT3) and its intracellular translocation were examined.', '1. High glucose and mannitol could up-regulate IL-6 mRNA expression and IL-6 secretion in mesothelial cells significantly, and there was no difference of its effect between high glucose and mannitol. 2. Met-5A was a cell line with a single IL-6 receptor. The IL-6/sIL-6R complex induced VEGF synthesis of mesothelial cells, which was alleviated by sgp130 or AG490. IL-6 trans-signaling could induce the phosphorylation of STAT3, which is recruited to the cellular nucleus of Met-5A cells.\Question: Does interleukin-6 trans-signaling induce VEGF synthesis partly via Janus kinases-STAT3 pathway in human mesothelial cells?

Ex Output:
The present study might provide evidence that high glucose up-regulates IL-6 synthesis in Met-5A cells, to some extent, depending on its osmolality and that IL-6 trans-signaling could induce VEGF synthesis partly dependent on the JAK/STAT3 pathway.

Ex Input:
Context: To investigate the mutation status of growth differentiation factor 15 (GDF15) in patients with oral squamous cell carcinoma (OSCC), as well as the prognostic value of missense GDF15 mutations.', 'Formalin-fixed paraffin-embedded biopsy samples from 46 OSCC patients were involved in this study. GDF15 and TP53 mutations were sequenced using the Ion Torrent Personal Genome Machine, GDF15 protein expression was detected using immunohistochemistry. Torrent Suite Software v.3.6, Integrative Genomics Viewer; v.2.3, statistical software SPSS18.0 for Windows were used for analysis. All hypothesis-generating tests were two-sided at a significance level of 0.05.', 'Twenty-nine GDF15 mutations were identified in 19 out of 46 patients (41.3%), including eighteen missense mutations, two nonsense mutations and nine synonymous mutations. The patients with missense GDF15 mutations had poorer prognostic outcomes than those with wild-type GDF15, including overall survival (P = 0.035), disease-free survival (P = 0.032), locoregional recurrence-free survival (P = 0.015), and distant metastasis-free survival (P = 0.070). Missense GDF15mutations was an independent increased risk factor of overall survival (HR = 5.993, 95% CI:1.856-19.346, P = 0.003), disease-free survival (HR = 3.764, 95% CI:1.295-10.945, P = 0.015), locoregional recurrence-free survival (HR = 4.555, 95% CI:1.494-13.889, P = 0.008), and distant metastasis-free survival (HR = 4.420, 95% CI:1.145-13.433, P = 0.009).\Question: Does mutant GDF15 present a poor prognostic outcome for patients with oral squamous cell carcinoma?

Ex Output:

Patients with missense GDF15 mutations have significantly poorer outcomes than those with wild-type GDF15, missense GDF15 mutations could be used as an independent increased risk factor of poor prognosis in OSCC patients.
