e NF-κB/p53/p21 pathway and attenuated the osteoblastic transition and calcification in VSMCs. CONCLUSIONS High levels of IL-1β in medial smooth muscles of arteries may play roles in inducing senescence-associated calcification. Choline IL-1β-induced senescence depending on the activation of the NF-κB/p53/p21 signaling pathway and contributing to osteoblastic transition of VSMCs. © 2020 The Author(s) Published by S.

However, there are numerous other non-anaphylactic conditions where clinicians may see elevated serum tryptase (hypertryptasemia) and the practicing clinician ought to be aware of these important differential diagnoses. Such conditions include systemic mastocytosis, hematological malignancies, and chronic kidney disease. This article provides a comprehensive, updated summary on the variety of non-anaphylactic conditions where hypertryptasemia may be seen. © 2020 S.

Achieving a diagnosis tool with high reliability and validity is essential. The Clinical Dementia Rating (CDR) is a global clinical scale with established diagnostic and severity-ranking utility that has been widely employed in epidemiological studies in an international context. OBJECTIVE The aims of this study were to establish the Vietnamese version of the CDR (V-CDR) and evaluate the feasibility, reliability, and validity of this version for diagnosing and classifying cognitive functions in the elderly. METHOD One hundred and fifty-three elderly outpatients at a clinic of Cho Ray Hospital, Vietnam, were screened with the Mini Mental State Examination (MMSE) for potential cognitive impairment. All those who scored ≤26 points were included in the study and were subsequently remitted to the V-CDR and clinical assessment for diagnosis. Reliability was assessed thmentia stages in the elderly. © 2020 S. Karger AG, Basel.OBJECTIVE Activin A is known to be highly expressed in rheumatoid synovium. In the present study, we investigated the effect of inflammatory cytokines on activin A production and its role in rheumatoid inflammation using freshly prepared rheumatoid synovial cells (fresh-RSC). METHODS Fresh-RSC from patients with rheumatoid arthritis were obtained and stimulated with multiple cytokines for activin A production. Gene expression levels of activin A and inflammatory cytokines were determined by quantitative PCR (qPCR) analysis. An enzyme-linked immunosorbent assay (ELISA) was used to measure activin A and CXCL10 in culture supernatants. The osteoclasts generated from human peripheral monocytes by RANKL stimulation were identified by tartrate-resistant acid phosphatase staining and bone resorption assay using Osteo plate. The expression levels of NFATc1 and cathepsin K, critical intracellular proteins for osteoclastogenesis, were determined by Western blotting. RESULTS Activin A production in fresh-RSC was markedly enhanced by the synergistic effect of TGF-β1 with inflammatory cytokines, including TNFα, IL-1β, and IL-6. Activin A inhibited TNFα-induced CXCL10, an important chemoattractant for pathogen-activated T cells and monocytes of osteoclast precursors, but it did not affect the expression of inflammatory cytokines and chemokines. In addition, activin A directly inhibited the expression of NFATc1 and cathepsin K, as well as osteoclast formation in human samples. CONCLUSION Our data indicated that TGF-β1 is involved in the expression of activin A at inflamed joints. Activin A mainly exerts an anti-inflammatory action, which prevents joint damage via the regulation of CXCL10 and osteoclastogenesis. © 2020 S.

However, an extensive analysis of safety data could demonstrate beneficial results in terms of effectiveness by reducing serious adverse events (SAEs), and their unfavourable clinical impact on the study population. We aimed to conduct an exploratory analysis of the CHInese Medicine Neuroaid Efficacy on Stroke recovery (CHIMES) study safety database comparing the frequency of SAEs and their clinical impacts among subjects having received MLC601 or placebo during the first 3 months post-stroke. METHODS Analyses were performed by using the safety database of the multicentre, randomised, double-blind, placebo-controlled CHIMES study of 3 months of NeuroAiD versus placebo in subjects with acute ischaemic stroke of intermediate severity in the preceding 72 h. SAEs as reported by investigators at any time-point during the 3-month study were analysed otalisation time, reduced in the MLC601 arm with the rate of subjects hospitalised for a prolonged period being significantly threefold lower in surviving subjects (1.1 vs. 3.7%; p less then 0.01). CONCLUSIONS This post hoc analysis of SAEs from the CHIMES study database shows that subjects receiving a 3-month course of MLC601 experienced fewer SAEs, with lower rates of harmful clinical impacts, especially in terms of hospitalisation duration. These findings could translate to a benefit in terms of reduction of both healthcare burden and additional medical costs. © 2020 The Author(s) Published by S.

But what type of action? Here we argue that restoration of primate habitat will be an essential component of strategies aimed at conserving primates and preventing the extinctions that may occur before the end of the century and propose that primates can act as flagship species for restoration efforts. To do this we gathered a team of academics from around the world with experience in restoration so that we could provide examples of why primate restoration ecology is needed, outline how primates can act as flagship species for restoration efforts of tropical forest, review what little is known about how primate populations respond to restoration efforts, and make specific recommendations of the next steps needed to make restoration of primate populations successful. We set four priorities (1) academics must effectively communicate both the value of primates and the need for restoration; (2) more research is needed on how primates contribute to forest restoration; (3) more effort must be put into Masters and PhD level training for tropical country nationals; and finally (4) more emphasis is needed to monitor the responses of regenerating forest and primate populations where restoration efforts are initiated.
