[Q]: Evodiamine is one of active alkaloids isolated from the traditional Chinese medicine Evodia rutaecarpa Bentham and has various pharmacological properties. In this study, we investigated its effects on the migration, invasion, and associated mechanism in human nasopharyngeal carcinoma (NPC) cells.', 'Cell viability was determined by MTT assay after evodiamine treatment. Wound-healing assay and Boyden transwell system were used to evaluate the inhibitory effects of evodiamine on cell migration and invasion. MMP-2/9 activity was determined using commercial detection kits. The levels of associated proteins involved in the regulation of cell migration and invasion were analyzed by Western blotting.', 'Evodiamine effectively inhibited the migration and invasion of HONE1 and CNE1 cells, and hardly affected cell proliferation, but significantly suppressed cell adhesion activity in vitro. Additionally, evodiamine treatment significantly decreased mRNA and protein levels of MMP-2 and its activity in the NPC cells, but had little effects on MMP-9 mRNA and protein levels and its activity. Further investigation revealed that evodiamine inhibited the translocation of NF-κB p65, which involves the regulation of MMP-2 expression in cancer invasion. Additionally, evodiamine treatment did not significantly affect the protein levels of JNK, p38, Akt, and their phosphorylated forms and ERK1/2, but strongly attenuated ERK1/2 phosphorylation level, which at least partly accounts for the signal pathway of evodiamine-inhibited migration and invasion of NPC cells.
[A]: Does evodiamine inhibit the migration and invasion of nasopharyngeal carcinoma cells in vitro via repressing MMP-2 expression?


[Q]: Complex regional pain syndrome (CRPS) is a painful condition with approximately 50,000 annual new cases in the United States. It is a major cause of work-related disability, chronic pain after limb fractures, and persistent pain after extremity surgery. Additionally, CRPS patients often experience cognitive changes, anxiety, and depression. The supraspinal mechanisms linked to these CRPS-related comorbidities remain poorly understood.', 'The authors used a previously characterized mouse model of tibia fracture/cast immobilization showing the principal stigmata of CRPS (n = 8 to 20 per group) observed in humans. The central hypothesis was that fracture/cast mice manifest changes in measures of thigmotaxis (indicative of anxiety) and working memory reflected in neuroplastic changes in amygdala, perirhinal cortex, and hippocampus.', 'The authors demonstrate that nociceptive sensitization in these mice is accompanied by altered thigmotactic behaviors in the zero maze but not open field assay, and working memory dysfunction in novel object recognition and social memory but not in novel location recognition. Furthermore, the authors found evidence of structural changes and synaptic plasticity including changes in dendritic architecture and decreased levels of synaptophysin and brain-derived neurotrophic factor in specific brain regions.

[Q]: In the Microbicide Trial Network MTN-003 (VOICE) study, a Phase IIB pre-exposure prophylaxis trial of daily oral or vaginal tenofovir (TFV), product adherence was poor based on pharmacokinetic (PK) drug detection in a random subsample. Here, we sought to compare behavioural and PK measures of adherence and examined correlates of adherence misreporting.', 'We included participants with PK and behavioural data from VOICE random subsample. Behavioural assessments included face-to-face interviews (FTFI), audio computer-assisted self-interviewing (ACASI) and pharmacy-returned product counts (PC). TFV concentrations < 0.31 ng/mL in plasma (oral group) and < 8.5 ng/swab in vaginal group were defined as "PK non-adherent." Logistic regression models were fit to calculate the combined predictive ability of the behavioural measures as summarized by area under the curve (AUC). Baseline characteristics associated with over-reporting daily product use relative to PK measures was assessed using a Generalized Linear Mixed Model.', 'In this random adherence cohort of VOICE participants assigned to active products, (N = 472), PK non-adherence was 69% in the oral group (N = 314) and 65% in the vaginal group (N = 158). Behaviourally, ≤ 10% of the cohort reported low/none use with any behavioural measure and accuracy was low (≤ 43%). None of the regression models had an AUC > 0.65 for any single or combined behavioural measures. Significant (p < 0.05) correlates of over-reporting included being very worried about getting HIV and being unmarried for the oral group; whereas for the vaginal group, being somewhat worried about HIV was associated with lower risk of over-reporting.
