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.

Aggressive periodontitis is characterized by rapid destruction of periodontal tissue caused by Aggregatibacter actinomycetemcomitans. Interleukin (IL)-1 is a proinflammatory cytokine, and its production is tightly regulated by inflammasome activation. Xylitol, an anticaries agent, is anti-inflammatory, but its effect on inflammasome activation has not been researched. This study investigates the effect of xylitol on inflammasome activation induced by A. actinomycetemcomitans.', 'The differentiated THP-1 macrophages were stimulated by A. actinomycetemcomitans with or without xylitol and the expressions of IL-1 and inflammasome components were detected by real time PCR, ELISA, confocal microscopy and Immunoblot analysis. The effects of xylitol on the adhesion and invasion of A. actinomycetemcomitans to cells were measured by viable cell count.', 'A. actinomycetemcomitans increased pro IL-1 synthesis and IL-1 secretion in a multiplicity of infection- and time-dependent manner. A. actinomycetemcomitans also stimulated caspase-1 activation. Among inflammasome components, apoptosis-associated speck-like protein containing a CARD (ASC) and absent in melanoma 2 (AIM2) proteins were upregulated by A. actinomycetemcomitans infection. When cells were pretreated with xylitol, proIL-1 and IL-1 production by A. actinomycetemcomitans infection was significantly decreased. Xylitol also inhibited ASC and AIM2 proteins and formation of ASC puncta. Furthermore, xylitol suppressed internalization of A. actinomycetemcomitans into differentiated THP-1 macrophages without affecting viability of A. actinomycetemcomitans within cells.

Expression of CINCs was regulated differentially in lipopolysaccharide-stimulated rat macrophages. We examined whether the expression of CINCs in lipopolysaccharide-stimulated rat macrophages is similarly inhibited by anti-inflammatory drugs.', 'Rat peritoneal macrophages were stimulated by lipopolysaccharide in the presence of anti-inflammatory steroids (dexamethasone, prednisolone and hydrocortisone) or non-steroidal anti-inflammatory drugs (indomethacin and piroxicam). The production and mRNA expression of three types of CINCs were measured using enzyme-linked immunosorbent assay and northern hybridization.', 'Anti-inflammatory steroids; dexamethasone, prednisolone and hydrocortisone, dose-dependently inhibited the production of CINC-1, -2 and -3, whose inhibitory patterns were similar to each other. Furthermore mRNA expression of each CINC was inhibited by dexamethasone in a dose-dependent manner. In contrast, non-steroidal anti-inflammatory drugs, indomethacin and piroxicam were without effect. Expression of each CINC was regulated differently; the production of CINC-1 reached a maximum at 12 h and then slightly decreased after lipopolysaccharide stimulation, whereas that of CINC-2 and CINC-3 increased up to 24 h. Dexamethasone inhibited the CINCs production and mRNA expression at 9 h after lipopolysaccharide stimulation.

Ex Output:
Is the expression of three types of CINCs by lipopolysaccharide-stimulated rat macrophages inhibited similarly by anti-inflammatory steroids?

To assess the rapid improvement of insulin sensitivity and -cell function following biliopancreatic diversion with duodenal switch (BPD-DS) and determine the role played by caloric restriction in these changes.', 'Standard meals were administrated before and on day 3, 4, and 5 after BPD-DS to measure total caloric intake, glucose excursion, insulin sensitivity, and secretion in matched type 2 diabetes and normoglycemic (NG) subjects. In a second set of study, other subjects with type 2 diabetes had the same meal tests prior to and after a 3-day caloric restriction identical to that observed after BPD-DS and then 3 days after actually undergoing BPD-DS.', 'Improvement of HOMA-IR occurred at day 3 after BPD-DS in diabetes and after 3 days of caloric restriction. The disposition index (DI) improved rapidly in diabetes after BPD-DS and to a similar extent after caloric restriction. DI was higher and did not change after BPD-DS in NG. Changes in glucagon-like peptide-1, gastric inhibitory peptide, peptide tyrosine tyrosine, ghrelin, and pancreatic polypeptide levels were not associated with modulation of DI in the participants.
