Hemophilic arthropathy is the most common chronic complication in patients with hemophilia. The pathogenesis of hemophilic arthropathy involves the inflammatory processes associated with rheumatoid arthritis (RA). Determining the severity and/or progression of joint damage is crucial when evaluating the effect of treatment modalities. Identifying reliable biomarkers in the peripheral blood of patients with hemophilic arthropathy may be beneficial in clinical practice. Circulating soluble vascular cell adhesion molecule-1 (sVCAM-1), E-selectin, and P-selectin levels are elevated in patients with RA...

Rosmarinic acid (RA) is an active component of a traditional Chinese herbal medicine. Previously, we reported that RA exerted a strong anti-inflammatory effect in a mouse acute lung injury model. Therefore, we hypothesized that RA might also have potential therapeutic effects in a murine model of asthma. In this study, we aimed to evaluate the anti-asthmatic activity of RA and explored its possible molecular mechanisms of action. Female BALB/c mice that had been sensitized to and challenged with ovalbumin (Ova) were treated with RA (20mg/kg) 1h after challenge...

Rosmarinic acid (RA) has numerous pharmacologic effects, including anti-oxidant, anti-inflammatory, and analgesic effects. This study aimed to evaluate the preventive activity of RA in a murine model of asthma and to investigate its possible molecular mechanisms. Female BALB/c mice sensitized and challenged with ovalbumin (Ova) were pretreated with RA (5, 10 or 20 mg/kg) at 1 h before Ova challenge. The results demonstrated that RA markedly inhibited increases in inflammatory cells and Th2 cytokines in the bronchoalveolar lavage fluid (BALF), significantly reduced the total IgE and Ova-specific IgE concentrations, and greatly ameliorated airway hyperresponsiveness (AHR) compared with the control Ova-induced mice...

INTRODUCTION: Although the role of platelets in rheumatoid arthritis (RA) is relatively unexplored, recent studies point towards a contribution of platelets in arthritis. We set out to determine platelet phenotype in RA and studied whether this could be influenced by the presence of anti-citrullinated protein antibodies (ACPA). METHODS: Platelets from healthy controls were incubated in the presence of plasma of patients with RA or age- and sex-matched healthy controls and plasma from ACPA(neg) or ACPA(pos) patients or in the presence of plate-bound ACPA...

Early diagnosis and effective monitoring of rheumatoid arthritis (RA) are important for a positive outcome. Instant treatment often results in faster reduction of inflammation and, as a consequence, less structural damage. Anatomical imaging techniques have been in use for a long time, facilitating diagnosis and monitoring of RA. However, mere imaging of anatomical structures provides little information on the processes preceding changes in synovial tissue, cartilage, and bone. Molecular imaging might facilitate more effective diagnosis and monitoring in addition to providing new information on the disease pathogenesis...

BACKGROUND AND OBJECTIVES: It has been known that the dominant driver of atrial fibrillation (AF) exists in the left atrium (LA) and the incidence of systemic thromboembolism is higher than that of pulmonary thromboembolism in patients with AF. Therefore, we hypothesized that histological and biochemical characteristics of the LA and the right atrium (RA) are different in patients with mitral valvular AF. SUBJECTS AND METHODS: We analyzed the histology and messenger ribonucleic acid (mRNA) or protein expression associated with endothelial function and thrombogenesis in 33 human atrial appendage tissues (20 LA tissues, 13 RA tissues) taken from 25 patients {57...

INTRODUCTION: Syndecans are heparan sulphate proteoglycans expressed by endothelial cells. Syndecan-3 is expressed by synovial endothelial cells of rheumatoid arthritis (RA) patients where it binds chemokines, suggesting a role in leukocyte trafficking. The objective of the current study was to examine the function of syndecan-3 in joint inflammation by genetic deletion in mice and compare with other tissues. METHODS: Chemokine C-X-C ligand 1 (CXCL1) was injected in the joints of syndecan-3-/-and wild-type mice and antigen-induced arthritis performed...

OBJECTIVES: To estimate endothelial dysfunction in patients with rheumatoid arthritis (RA) of short duration in relation to disease activity based on the assessment of 28 joints (DAS28). METHODS: We studied 29 patients (22 women, mean age 41 (SD, 9) years) with RA of short duration and 29 healthy controls. The RA subjects were divided into those with low (DAS28: 2.6-5.1, n = 18) or high (DAS28 > 5.1, n = 11) disease activity. Exclusion criteria included clinically overt atherosclerosis and other coexistent diseases...

OBJECTIVE: Rheumatoid arthritis (RA) is one of the most frequent inflammatory diseases, causing pain and disability in the affected joints. Early diagnosis is essential for the efficiency of symptom-targeting treatments, but its diagnosis requires careful clinical, serologic, and imaging examinations, such as magnetic resonance imaging (MRI), which is both expensive and time consuming. In an effort to provide the biomedical community with a more accessible way to assess the advancement of arthritis, this study sought to investigate the use of multispectral optoacoustic tomography (MSOT) in a murine arthritis model, to visualize the extent of inflammation in vivo through an L-selectin/P-selectin-targeting contrast agent...

A relapse of lower-limb varicose disease (LLVD), despite the development of surgical achievements in surgical technologies is currently an important problem of present-day phlebology. A considerable factor of its pathogenesis is endothelial dysfunction (ED). The results of clinical studies of "false" relapses (n=32) and the control group were indicative of pronounced ED. Studying the level of leukocytes confirmed a hypothesis on a "leukocytic" trap at the level of the varicose veins of lower extremities. The authors analysed the dynamics of certain markers of ED (CECs, VCAM-1, P-selectin, E-selectin t-RA, endothelin-1), suggestive of the degree of ED severity, revealing a tendency towards normalization of the ED markers on the background of phlebotrophic therapy (Antistax)...

INTRODUCTION: Whether adiponectin levels associate with atherogenesis in RA is uncertain. We examined the independent relationships of total and high molecular weight (HMW) adiponectin concentrations with cardiometabolic risk and surrogate markers of enhanced early atherogenesis in black and white patients with RA. METHODS: We determined total and HMW adiponectin concentrations and those of endothelial activation molecules including soluble E-selectin, vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and monocyte chemoattractant protein-1 (MCP-1), in 210 (119 black and 91 white) RA patients...

Dendritic cells from mesenteric lymph nodes (MLN) can convert retinal to retinoic acid (RA), which promotes induction of the gut-specific homing receptor α4β7. In contrast, priming within peripheral lymph nodes leads to upregulation of E- and P-selectin ligands (E- and P-lig). Apart from its α4β7 promoting effect, RA was shown to suppress E- and P-lig induction in vitro. However, enhanced frequencies of P-lig(+) CD4(+) T cells were reported during intestinal inflammation. To understand this contradiction, we first determined whether location of intestinal inflammation, that is, ileitis or colitis, affects P-lig induction...

Chronic inflammation plays an important role in atherogenesis. Experimental studies have demonstrated the accumulation of monocytes/macrophages in atherosclerotic plaques caused by inflammation. Here, we report the inhibitory effects of lipoteichoic acid (LTA) from Lactobacillus plantarum (pLTA) on atherosclerotic inflammation. pLTA inhibited the production of proinflammatory cytokines and nitric oxide in lipopolysaccharide (LPS)-stimulated cells and alleviated THP-1 cell adhesion to HUVEC by down-regulation of adhesion molecules such as intracellular adhesion molecule-1 (ICAM-I), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin...

OBJECTIVES: Rheumatoid arthritis (RA) is associated with accelerated atherosclerosis and premature cardiovascular death. Anti-TNF therapy is thought to reduce clinical cardiovascular disease risk and improve vascular function in RA patients. However, the specific effects of TNF inhibitors on endothelial cell function are largely unknown. Our aim was to explore the effects of certolizumab pegol (CZP) on TNF-activated human aortic endothelial cells (HAoECs). METHODS: HAoECs were cultured in vitro and exposed to i) TNF alone, ii) TNF plus CZP, or iii) neither agent...
