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.

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).

Ex Output:
Does ganoderma lucidum induce the expression of CD40/CD86 on peripheral blood monocytes?

While the anticholinergic activity of medications has been linked to cognitive decline, few studies have linked anticholinergic burden with falls in older people. We evaluated the relationship between anticholinergic burden and recurrent and injurious falls among community-dwelling older adults.', 'This case-control study was performed on 428 participants aged 65 years, 263 cases with two or more falls or one injurious fall in the preceding 12 months, and 165 controls with no falls in the preceding 12 months. Anticholinergic burden was determined using the anticholinergic cognitive burden (ACB) scale. Upper and lower limb functional abilities were assessed with timed up and go (TUG), functional reach (FR) and grip strength (GS). Logistic regression analysis was employed to calculate the mediation effect of TUG, FR and GS on ACB associated falls.', 'Univariate analysis revealed a significant association between an ACB score of 1 with falls (OR, 1.8; 95% CI; 1.1-3.0; p=0.01) and significantly poorer TUG and FR. The association between ACB1 and falls was no longer significant after adjustment for either TUG (OR for ACB associated falls, 1.4; 95% CI, 0.88-2.4; p=0.14) or FR (OR for ACB associated falls, 1.4; 95% CI, 0.89-2.4, p=0.12) but remained significant with GS.

Is anticholinergic burden associated with recurrent and injurious falls in older individuals?

Effective material exchange between blood and tissue depends on the heterogeneity of microvascular flow. The objective was to address inconsistencies between intravital studies regarding this dependency. We tested the hypothesis that heterogeneity of red blood cell velocity (VRBC) in capillary beds varies with the strength of metabolic stimulus and with capillary bed geometry.', 'We used videomicroscopy to measure VRBC in a bed of 10-24 capillaries at the surface of extensor digitorum longus (EDL) muscle in anesthetized rats. The coefficient of variation (CV = standard deviation/mean; an index of spatial heterogeneity) was computed in the same bed before and after (i) 1, 2, 4, or 8 Hz supramaximal muscle contraction or (ii) adenosine superfusion (10(-7)-10(-3) M). Beds with or without arteriolar-venular capillary shunts were used.', 'Although control VRBC differed between beds (shunt: 232 microns/s; no shunt: 130 microns/s), the percentage increases in postcontraction VRBC did not (range: 111-326%). In both beds, control CV varied greatly (overall range: 28-117%) and 2-8 Hz muscle contractions reduced CV significantly by 25%. Similar results were obtained for adenosine. In confirmatory experiments using the rat cremaster muscle, contractions (4 Hz) and adenosine (10(-4) M) also reduced CV. Based on all data, CV = 63-0.022 VRBC (r = 0.82, P < 0.001).
