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.

The major immuno-modulating effects of Ganoderma lucidum include mitogenicity and activation of immune effector cells such as T cells, macrophages and natural killer cells resulting in the production of cytokines.', 'The purpose of this study was to evaluate the expression of CD40 and CD80 by G. lucidum-treated human peripheral blood mononuclear cells.', 'Monocytes were isolated and incubated at 37 C and 5% CO2 for 24 h and 48 h in the presence or absence of different concentrations of G. lucidum. Cells were then incubated with labelled monoclonal antibodies against CD14, CD40 and B7-1(CD80) molecules utilizing standard protocols, and analyzed by flow cytometry.', 'The results showed that incubation of monocytes with G. lucidum led to marked enhancement of CD40 and B7-1 expression in a dose- and time- dependent manner (p<0.001). G. lucidum was more effective in enhancing the expression of CD80 and CD40 molecules of cells obtained from females than male donors (p<0.001).
Does ganoderma lucidum induce the expression of CD40/CD86 on peripheral blood monocytes?

Pathological evidence supports a potential role of the pro- and anti-inflammatory cytokine network in the pathogenesis of inflammatory bowel disease (IBD). Moreover, associated studies suggest a possible involvement of cytokine-related genes in IBD susceptibility. In this study, we evaluated the effect of the anti-inflammatory interleukin-10 (IL10) gene on ulcerative colitis (UC).', 'Two functional single nucleotide polymorphisms (-1082 G/A, -819 T/C) in the IL10 promoter in 203 Italian sporadic UC patients and 391 controls were determined using high-resolution melting analysis.', 'The frequency of the -1082A allele was significantly higher in the UC patients than in controls (p=0.00003); -1082 genotype frequencies were also significantly different between UC patients and controls (p=0.0001). Allele and genotype frequencies of -819 T/C were not significantly associated with UC. Furthermore, the frequencies of haplotypes -1082A/-819C and -1082A/-819T, which have been reported to have a lower promoter activity, were significantly higher in UC patients than in controls (p=0.0004). After gender stratification, we found a significant difference in the -1082A allele (p=0.00004) and genotype (p=0.0002) frequencies only between female UC patients and controls; the same result was obtained for the -1082A/-819C and -1082A/-819T haplotypes (p=0.0006).
Do interleukin-10 promoter polymorphisms influence susceptibility to ulcerative colitis in a gender-specific manner?

Little is known about the potentiating effect of propofol on neuromuscular blocking drugs. However, some animal studies indicate a dose-dependent increase of the potency of neuromuscular blocking drugs by propofol. This study compared mivacurium potency after five minutes and after 20 min of total intravenous anesthesia with propofol (TIVA propofol).', 'Twenty-eight patients were randomized into two groups, after approval of the Ethics Committee and written consent. Anesthesia was induced, in all patients, using remifentanil 0.5 microg.kg(-1).min(-1) for two minutes, after which: 3 mg.kg(-1) of propofol was injected; a laryngeal mask airway was inserted; and intermittent, positive pressure ventilation was initiated. Anesthesia was maintained using TIVA propofol (titrated using bispectral index monitoring to 40-45). Neuromuscular monitoring consisted of phonomyography at the adductor pollicis muscle. In Groups 5 min and 20 min, a tetanic stimulation of the ulnar nerve commenced after four minutes and after 19 min of TIVA, respectively, followed by controlled, single twitch stimulation at 1 Hz for one minute. Boli of 60, 30, 30, and 30 microg.kg(-1) mivacurium, respectively, were administered (each drug increment was administered after the effect of the previous dose had caused a stable response), and single twitch stimulation continued at 0.1 Hz. The dose-response curve was determined for both groups; potency was calculated using log-probit analysis. Data were presented as mean (SD) and were compared using two-sided analysis of variance, P < 0.05.', 'Patient characteristics were similar in the two groups. The corresponding ED(50) and ED(95) values were greater, at 76.7 +/- 12.4 microg.kg(-1) and 146.6 +/- 27.6 microg.kg(-1) for Group 5 min, vs 46.7 +/- 12.2 microg.kg(-1) and 101.1 +/- 20.2 microg.kg(-1) for Group 20 min, respectively.

Does total intravenous anesthesia with propofol augment the potency of mivacurium?
