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.

Context: The goals of this study were to determine if β-acid from hops (Humulus lupulus L.) could be used to control fructan fermentation by equine hindgut micro-organisms, and to verify the antimicrobial mode of action on Streptococcus bovis, which has been implicated in fructan fermentation, hindgut acidosis and pasture-associated laminitis (PAL) in the horse.', 'Suspensions of uncultivated equine faecal micro-organisms produced fermentation acids when inulin (model fructan) was the substrate, but β-acid (i.e. lupulone) concentrations ≥9\xa0ppm inhibited lactate production and mitigated the decrease in pH. Inulin-fermenting Strep.\xa0bovis was isolated from the β-acid-free suspensions after enrichment with inulin. The isolates were sensitive to β-acid, which decreased the viable number of streptococci in faecal suspensions, as well as growth, lactate production and the intracellular potassium of Strep.\xa0bovis in pure culture.\Question: Does inhibition of fructan-fermenting equine faecal bacteria and Streptococcus bovis by hop ( Humulus lupulus L. ) β-acid?
These results are consistent with the hypothesis that hops β-acid prevented the growth of fructan-fermenting equine faecal bacteria, and that the mechanism of action was dissipation of the intracellular potassium of Strep. bovis.

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?
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.

Context: We examined the influence of head-tilting on stabilometry, which is similar to positional nystagmus in a sitting position.', "The subjects were 35 healthy individuals and 11 patients with unilateral vestibular disorder. We compared parameters measured in an upright position and those with left head-tilt or right head-tilt. We used Wilcoxon's signed ranks test for statistical analysis.", 'In the group of healthy adults, the Enveloped area with left head-tilt and right head-tilt increased significantly compared to that in the upright position (P=0.0111). The parameters that decreased significantly were Locus length per unit area (P=0.0007). The center of gravity on the Y-axis shifted backward significantly (P<0.0001). In the group of unilateral vestibular disorder, there were no parameters that showed significant difference\Question: Does comparison between stabilometry with and without head tilt in a roll plane?

One could argue that a combination of displacement of the body itself, influence of proprioceptive sensation, and influence of otolith affects the output of stabilometry. It would be possible to develop this test if the first and the second are excluded.
