[EX Q]: Chronic systemic inflammation plays a pivotal role in the development of atherosclerosis in rheumatoid arthritis (RA). In the present study, we investigated whether anti-TNF-alpha antagonist-monoclonal antibody-infliximab administration alters circulating levels of resistin, a proinflammatory adipokine. We further assessed associations of circulating resistin concentrations with CRP and ESR levels, platelet counts and metabolic syndrome and demographic characteristics in RA patients on periodical treatment with infliximab.', 'We investigated 33 patients with RA on periodical treatment with infliximab. Serum resistin levels were determined immediately prior to and after infliximab infusion.', 'Upon infliximab administration, mean (SD) serum resistin concentrations (ng/ml) decreased from 21.9 (9.9) to 17.4 (8.9) (p=0.005). Also, a significant association between the mean ESR (r=0.405; p=0.03) and CRP (r=0.571; p=0.0005) from disease diagnosis and ESR (r=0.486; p=0.004), CRP (r=0.599; p=0.0005) and platelet count (r=0.559; p=0.0007) at the time of the study and baseline resistin levels was found.

[EX Q]: Proinflammatory cytokines have the potential to activate the hypothalamo-pituitary-adrenocortical (HPA) axis, and HPA axis hyperactivity is also encountered in depression. Therefore, the induction of depressive symptoms by interferon-alpha (IFN-alpha) may be mediated by changes in the cytokine network and the HPA axis.', 'In 17 hepatitis C patients undergoing IFN-alpha treatment, depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS). In addition, serum cytokine concentrations were measured. Saliva was collected five times over the course of a day in order to assess daily average cortisol (DAC) and awakening response. Assessments were carried out at baseline and six later time points after starting treatment.', 'During treatment, the increases in the MADRS were significantly and positively correlated with soluble interleukin (IL)-2 receptor, tumor necrosis factor alpha (TNF-alpha), and IL-6. There were no significant associations between the DAC or cortisol awakening response with the MADRS score.
[EX A]: Are interferon-alpha-induced depressive symptoms related to changes in the cytokine network but not to cortisol?

[EX Q]: The important functions of the meniscus are shock absorption, passive stabilization and load transmission of the knee. Because of the avascularity of two-thirds of the meniscal center region, the treatment of tears in this area is hard. Recently, microRNAs have been proven to play an important role in the pathogenesis of diseases. We focused on microRNA (miR)-210, which plays a wide spectrum of roles comprising mitochondrial metabolism, angiogenesis, DNA repair and cell survival. This study aimed to investigate the effect of intra-articular injection of synthetic miR-210 on the injured meniscus in the avascular zone.', 'The middle segments of the medial meniscus of Spraque Dawley rats were incised longitudinally with a scalpel. An intra-articular injection of double-stranded (ds) miR-210 (for control group using control dsRNA) with atelocollagen was administered immediately after injury. Four weeks and 12\xa0weeks after the injection, we conducted a histologic evaluation, immunohistochemical evaluation and Real-time PCR analysis. In vitro, the inner meniscus and synovial cells were isolated from rat knee joint, and were transfected with ds miR-210 or control dsRNA. Real-time PCR and immunohistochemical evaluations were performed.', 'Twenty-four hours after the injection, FAM (Fluorescein amidite) labeled miR-210 was observed in the cells around the injured site. Four weeks after the injection, the injured site of the miR-210 group was filled with repaired tissue while that of the control was not repaired. In gene expression analysis of the meniscus, the expression of miR-210, Collagen type 2 alpha 1 (Col2a1), Vascular endothelial growth factor (VEGF), and Fibroblast growth factor-2 (FGF2) in the miR-210 group was significantly higher than that in the control. At 12\xa0weeks, the intra-articular injection of miR-210 had healed the injured site of the meniscus and had prevented articular cartilage degeneration. In vitro, miR-210 upregulated Col2a1 expression in the meniscus cells and VEGF and FGF2 expression in the synovial cells.
