[EX Q]: Context: To investigate the effects of quercetin, an herbal flavonoid, on LPS-induced delay in spontaneous apoptosis, adhesion molecules (CD62L, CD11b/CD18) expression of neutrophils, and superoxide (O(2)(-)) generation by LPS-primed fMLP-induced human neutrophils.', 'Neutrophils were incubated in the presence or absence of lipopolysaccharide (LPS) at a final concentration of 1 microg/ml for 24 hours. Some wells with neutrophils were pre-treated with quecetin at the final concentration ranging from 0-100 microM for 30 min and then 1 microg/ml LPS was added into the cultures for 24 hours. The apoptosis of neutrophils was evaluated by flowcytometry analysis of propidum iodide (PI)-staining of the nuclei and annexin V staining of phosphatidylserine (PS) in the cell membrane. Agarose gel electrophoresis of low molecular weight DNA was performed to analyze DNA fragmentation. The effects of quercetin on adhesion molecules were detected by using flowcytometry analysis. The generation of O(2) (-) by LPS-primed fMLP-induced neutrophils was determined by reduced cytochrome c assay.', 'LPS markedly inhibited the spontaneous apoptosis of neutrophils, but the inhibitory effect was abrogated after the pre-treatment of neutrophils with quercetin (approximately 40 microM) for 30 min. Quercetin (40 microM) also prevented LPS-induced down-regulation of CD62L expression, up-regulation of CD11b/CD18 expression, and O(2) (-) generation by fMLP-induced neutrophils.
Answer: As one of the pro-inflammatory factors, LPS aggravates inflammation through priming neutrophils to synthesize/release cytotoxic contents and prolonging functional lifespan of neutrophils by delaying the spontaneous apoptosis. Thus, our data suggest to us that quercetin might decrease the susceptibility of neutrophils to pro-inflammatory factors (e. g. LPS), which could partially explain the anti-inflammatory mechanisms of quercetin.
[EX A]: Does quercetin inhibit LPS-induced delay in spontaneous apoptosis and activation of neutrophils?

[EX Q]: Context: To test whether a brief mindfulness meditation training intervention buffers self-reported psychological and neuroendocrine responses to the Trier Social Stress Test (TSST) in young adult volunteers. A second objective evaluates whether pre-existing levels of dispositional mindfulness moderate the effects of brief mindfulness meditation training on stress reactivity.', 'Sixty-six (N=66) participants were randomly assigned to either a brief 3-day (25-min per day) mindfulness meditation training or an analytic cognitive training control program. All participants completed a standardized laboratory social-evaluative stress challenge task (the TSST) following the third mindfulness meditation or cognitive training session. Measures of psychological (stress perceptions) and biological (salivary cortisol, blood pressure) stress reactivity were collected during the social evaluative stress-challenge session.', 'Brief mindfulness meditation training reduced self-reported psychological stress reactivity but increased salivary cortisol reactivity to the TSST, relative to the cognitive training comparison program. Participants who were low in pre-existing levels of dispositional mindfulness and then received mindfulness meditation training had the greatest cortisol reactivity to the TSST. No significant main or interactive effects were observed for systolic or diastolic blood pressure reactivity to the TSST.
Answer: The present study provides an initial indication that brief mindfulness meditation training buffers self-reported psychological stress reactivity, but also increases cortisol reactivity to social evaluative stress. This pattern may indicate that initially brief mindfulness meditation training fosters greater active coping efforts, resulting in reduced psychological stress appraisals and greater cortisol reactivity during social evaluative stressors.
[EX A]: Does brief mindfulness meditation training alter psychological and neuroendocrine responses to social evaluative stress?

[EX Q]: Context: Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others.", 'To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns.', "Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others.", 'One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern.
Answer: Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

Does concern for Lost Income Following Donation deter Some Patients From Talking to Potential Living Donors?
