TL;DR: By inhibiting Dickkopf-1 (DKK-1), a regulatory molecule of the Wnt pathway, this work was able to reverse theBone-destructive pattern of a mouse model of rheumatoid arthritis to the bone-forming pattern of osteoarthritis, suggesting that the WNT pathway is a key regulator of joint remodeling.
Abstract: Degenerative and inflammatory joint diseases lead to a destruction of the joint architecture. Whereas degenerative osteoarthritis results in the formation of new bone, rheumatoid arthritis leads to bone resorption. The molecular basis of these different patterns of joint disease is unknown. By inhibiting Dickkopf-1 (DKK-1), a regulatory molecule of the Wnt pathway, we were able to reverse the bone-destructive pattern of a mouse model of rheumatoid arthritis to the bone-forming pattern of osteoarthritis. In this way, no overall bone erosion resulted, although bony nodules, so-called osteophytes, did form. We identified tumor necrosis factor-a (TNF) as a key inducer of DKK-1 in the mouse inflammatory arthritis model and in human rheumatoid arthritis. These results suggest that the Wnt pathway is a key regulator of joint remodeling. Affliction of joints is the hallmark of rheumatic disease. In addition to pain, both degenerative and inflammatory rheumatic diseases lead to a profound remodeling of the joint architecture, which causes functional disability and progressive crippling. This structural damage is largely responsible for the high socioeconomic burden of rheumatic disease, and definition of its molecular mechanism is therefore of key interest 1 .

TL;DR: The first report from the OMERACT ultrasound special interest group is presented, which has compared US against the criteria of the O MERACT filter, and for the first time are consensus US definitions for common pathological lesions seen in patients with inflammatory arthritis.
Abstract: Ultrasound (US) has great potential as an outcome in rheumatoid arthritis trials for detecting bone erosions, synovitis, tendon disease, and enthesopathy. It has a number of distinct advantages over magnetic resonance imaging, including good patient tolerability and ability to scan multiple joints in a short period of time. However, there are scarce data regarding its validity, reproducibility, and responsiveness to change, making interpretation and comparison of studies difficult. In particular, there are limited data describing standardized scanning methodology and standardized definitions of US pathologies. This article presents the first report from the OMERACT ultrasound special interest group, which has compared US against the criteria of the OMERACT filter. Also proposed for the first time are consensus US definitions for common pathological lesions seen in patients with inflammatory arthritis.

TL;DR: Hepatic platelet-endothelial interaction is an early event during endotoxemia, which underlines the probable involvement of platelets in leukocyte recruitment and makes the existence of autoregulatory liver mechanisms likely.
Abstract: Introduction
Liver microcirculation disturbances are a cause of hepatic failure in sepsis. Increased leukocyte-endothelial interaction, platelet adherence and impaired microperfusion cause hepatocellular damage. The time course and reciprocal influences of ongoing microcirculatory events during endotoxemia have not been clarified.

TL;DR: It is demonstrated that CD4+CD25+CD45RO+ T cells are present in the blood of adult healthy volunteers, and these cells do not constitute conventional memory cells but rather regulatory cells exhibiting properties identical to their rodent counterparts.
Abstract: It has been known for years that rodents harbor a unique population of CD4+CD25+ “professional” regulatory/suppressor T cells that is crucial for the prevention of spontaneous autoimmune diseases. Here we demonstrate that CD4+CD25+CD45RO+ T cells (mean 6% of CD4+ T cells) are present in the blood of adult healthy volunteers. In contrast to previous reports, these CD4+CD25+ T cells do not constitute conventional memory cells but rather regulatory cells exhibiting properties identical to their rodent counterparts. Cytotoxic T lymphocyte–associated antigen (CTLA)-4 (CD152), for example, which is essential for the in vivo suppressive activity of CD4+CD25+ T cells, was constitutively expressed, and remained strongly upregulated after stimulation. The cells were nonproliferative to stimulation via their T cell receptor for antigen, but the anergic state was partially reversed by interleukin (IL)-2 and IL-15. Upon stimulation with allogeneic (but not syngeneic) mature dendritic cells or platebound anti-CD3 plus anti-CD28 the CD4+CD25+ T cells released IL-10, and in coculture experiments suppressed the activation and proliferation of CD4+ and CD8+ T cells. Suppression proved IL-10 independent, yet contact dependent as in the mouse. The identification of regulatory CD4+CD25+ T cells has important implications for the study of tolerance in man, notably in the context of autoimmunity, transplantation, and cancer.

TL;DR: This paper presents an overview on current risk assessments done by expert panels as well as on exposure assessment data, based on ambient and on current human biomonitoring results, that prove that the tolerable intake of children is exceeded to a considerable degree.
