TAMpering with Toll-like Receptor Signaling

Toll-like receptors (TLRs) provoke a profound inflammatory response during host defense and must be controlled in order to avoid autoimmune and inflammatory diseases. In this issue, Rothlin et al. (2007) uncover a complex negative feedback mechanism to limit TLR signaling involving the Tyro3/Axl/Mer (TAM) family of receptor tyrosine kinases, which induce expression of the inhibitory proteins SOCS1 and SOCS3

Toll-like receptors and NOD-like receptors in rheumatic diseases

The past 10 years have seen the description of families of receptors that drive proinflammatory cytokine production in infection and tissue injury. Two major classes have been examined in the context of inflammatory joint disease - the Toll-like receptors (TLRs) and NOD-like receptors (NLRs). TLRs such as TLR2 and TLR4 are being implicated in the pathology of rheumatoid arthritis, ankylosing spondylitis, lyme arthritis and osteoarthritis. Nalp3 has been identified as a key NLR for IL-1β production and has been shown to have a particular role in gout. These findings present new therapeutic opportunities, possibly allowing for the replacement of biologics with small molecule inhibitors

A prospective cohort study measuring cost-benefit analysis of the Otago Exercise Programme in Community Dwelling Adults with Rheumatoid Arthritis

Det er en sammenheng mellom bachelorstudentenes karakterpoeng fra videregående skole og resultater til eksamen i anatomi, fysiologi, biokjemi (AFB). Enkelte studenter med lavere opptakskarakterer enn landsgjennomsnittet oppnådde bedre eksamensresultat enn det nasjonale gjennomsnittsresultatet i AFB for 2016. Hensikten med studien var å undersøke hvordan bachelorstudenter i sykepleie med lave opptakspoeng og gode eksamensresultater i AFB lærte og tilegnet seg emnet. Studien har et kvalitativ forskningsdesign og det ble gjennomført semistrukturerte intervju av 12 bachelorstudenter i sykepleie, som ble analysert ved hjelp av innholdsanalyse. Funnene er beskrevet ut fra tre hovedkategorier: A) Relevansen til sykepleieryrket styrker læring, B) tilhørighet har betydning for læring, og C) læring skjer i samarbeid med andre. Vi fant at studentene lærte AFB mer inngående i samhandling med andre studenter. Samlinger på campus er viktig for studenters læring, til tross for at det er stort fokus på fleksible utdanninger og digitale pedagogiske metoder. Selvstendig arbeid kombinert med læring i et sosialt studentfellesskap, oppgis som motivasjonsfaktorer til målrettet arbeid med studiene. Studentene erfarer mestringsforventning, i et miljø som preges av anerkjennelse og samtidig gir opplevelse av tilhørighet. Studentene vektlegger studienes relevans sett i lys av det profesjonsyrket som de utdanner seg til, som en betydningsfull motivasjonsfaktor for læring.publishedVersio

The Cytokine Release Inhibitory Drug CRID3 Targets ASC Oligomerisation in the NLRP3 and AIM2 Inflammasomes

Background: The Inflammasomes are multi-protein complexes that regulate caspase-1 activation and the production of the pro-inflammatory cytokine IL-1 beta. Previous studies identified a class of diarylsulfonylurea containing compounds called Cytokine Release Inhibitory Drugs (CRIDs) that inhibited the post-translational processing of IL-1 beta. Further work identified Glutathione S-Transferase Omega 1 (GSTO1) as a possible target of these CRIDs. This study aimed to investigate the mechanism of the inhibitory activity of the CRID CP-456,773 (termed CRID3) in light of recent advances in the area of inflammasome activation, and to clarify the potential role of GSTO1 in the regulation of IL-1 beta production

Examining the transnational health preferences of a group of Eastern European migrants relative to a European host population using the EQ-5D-5L.

The concept of transnationalism may provide an alternative rationale to observed differences in patterns of migrant healthcare use and health-related behaviours. In this study, we examined the health preferences of Eastern European migrants residing in another European state relative to comparable natives through the prism of transnationalism. For the analysis, we focused on the health preferences of 87 Polish migrants living full-time in Ireland compared to 87 Irish natives. We used EQ-5D-5L composite Time Trade-Off (cTTO) utility data collected as part of the Irish value set during 2015/2016 to examine the health preferences of both groups. Propensity score matching was utilised to match comparable Irish respondents to Polish migrants with 1:1 matching. Since cTTO utility data is censored, a random effects Tobit model was used to explore differences in utility valuations, and in a secondary analysis, we examined the likelihood of applying a negative utility valuation using a random effects logit model. The results from this study demonstrate that on average Polish migrants apply a significantly greater disutility valuation to health states and are more likely to apply a negative utility valuation to a given health state when compared to comparable natives. Differences in utility valuations can be seen as indicative of time preference with a greater disutility valuation being associated with a higher rate of time preference. This finding may be suggestive of health-related behaviours, such as a greater likelihood of not engaging with preventive service use in as far as those with high rates of time preference have low uptake. Transnationalism can underpin the observed differences in health preferences between the Polish migrants and comparable Irish natives. Transnational ties shape health-related behaviours of migrants from the use of healthcare services to health preferences. The results of this study will be of interest to policymakers in Ireland and Europe

Surface, Thermal and Antimicrobial Release Properties of Plasma-Treated Zein Films

The effects of dielectric barrier discharge plasma treatment on zein film containing thymol as an active ingredient were evaluated. The plasma discharge was optically characterized to identify the reactive species. A significant increase in the film roughness (p 0.05) was observed for the thermal properties of the antimicrobial films after DBD plasma treatment

Characterization of polylactic acid films for food packaging as affected by dielectric barrier discharge atmospheric plasma

Dielectric barrier discharge (DBD) air plasma is a novel technique for in-package decontamination of food, but it has not been yet applied to the packaging material. Characterization of commercial polylactic acid (PLA) films was done after in-package DBD plasma treatment at different voltages and treatment times to evaluate its suitability as food packaging material. DBD plasma increased the roughness of PLA film mainly at the site in contact with high voltage electrode at both the voltage levels of 70 and 80 kV. DBD plasma treatments did not induce any change in the glass transition temperature, but significant increase in the initial degradation temperature and maximum degradation temperature was observed. DBD plasma treatment did not adversely affect the oxygen and water vapor permeability of PLA. A very limited overall migration was observed in different food simulants and was much below the regulatory limits. Industrial relevance: In-package DBD plasma is a novel and innovative approach for the decontamination of foods with potential industrial application. This paper assesses the suitability of PLA as food packaging material for cold plasma treatment. It characterizes the effect of DBD plasma on the packaging material when used for in-package decontamination of food. The work described in this research offers a promising alternative to classical methods used in fruit and vegetable industries where in-package DBD plasma can serve as an effective decontamination process and avoids any post-process recontamination or hazards from the package itself
