levels of PNC measured and the good correlation with EC suggest that UFP exposures should receive more attention on occupational routine measurements and regulations. © The Author(s) 2020.

We describe correlations between laboratory parameters and treatment duration (r= -0.637; p=0.002) and time to virus recrudescence (r= 0.52; p=0.008) respectively, suggesting the need for additional measures to confirm illness resolution in COVID-19 patients. © The Author(s) 2020.

For permissions, e-mail [email protected] thrombocythemia (ET) is characterized by abnormal megakaryopoiesis and enhanced thrombotic risk. Once-daily (od), low-dose aspirin is the recommended antithrombotic regimen, but accelerated platelet generation may reduce the duration of platelet cyclooxygenase (COX)-1 inhibition. We performed a multicenter, double-blind trial to investigate the efficacy of three aspirin regimens in optimizing platelet COX-1 inhibition while preserving COX-2-dependent vascular thromboresistance. Two-hundred-forty-five patients on chronic od low-dose aspirin were randomized (111) to receive 100 mg aspirin od, twice-daily, bid), or three-times daily (tid) for 2 weeks. Serum thromboxane B2 (sTXB2), a validated biomarker of platelet COX-1 activity, and urinary prostacyclin metabolite (PGIM) excretion were measured at randomization and after 2 weeks, as primary surrogate endpoints of efficacy and safety, respectively. Urinary TX metabolite (TXM) excretion, gastrointestinal tolerance, and ET-related symptoms were also investigated. Evaluable patients assigned to the bid and tid regimens showed substantially reduced inter-individual variability and lower median values of sTXB2 19.3[9.7-40], 4 [2.1-6.7], and 2.5[1.4-5.65] ng/ml in the od (n=85), bid (n=79) and tid (n=79) arms, respectively. Urinary PGIM was comparable in the three arms. Urinary TXM was significantly reduced by 35% in both experimental arms. Patients in the tid arm reported a higher abdominal discomfort score. In conclusion, the currently recommended aspirin regimen of 75-100 od for cardiovascular prophylaxis appears largely inadequate in reducing platelet activation in the vast majority of ET patients. The antiplatelet response to low-dose aspirin can be markedly improved by shortening the dosing interval to 12 hours, with no improvement by further reducing it. (EudraCT 2016-002885-30).

This single-system case series aimed to explore the effects of eccentric training on spasticity-related resistance to passive motion in people with multiple sclerosis with elbow flexor spasticity. METHODS Six people with multiple sclerosis (median EDSS = 4.8, range = 2.0-5.5; Modified Ashworth Scale, MAS, score ≤ 3) underwent a 6-week eccentric strength training of the spastic muscles. Before and after the intervention, the following outcomes were assessed resistive peak torque (RPT), isometric strength, resting limb position, passive (PROM) and active (AROM) range of motion, severity of hypertonia by MAS, and numerical rating scale (NRS). At baseline, the primary outcome (RPT) was tested over 3 time points to ensure a stable measurement. The 2-standard deviations (SD) method was used to test Pre-Post training effects at individual level. Group-level analyses were also perfoiation.Polyclonal anti-D (RhIg) therapy has mitigated hemolytic disease of the newborn over the past half century, though breakthrough anti-D alloimmunization still occurs in some treated females. We hypothesized that antiviral responses may impact the efficacy of immunoprophylaxis therapy in a type 1 interferon (IFN)-dependent manner and tested this hypothesis in a murine model of KEL alloimmunization.Polyclonal anti-KEL immunoprophylaxis (KELIg) was administered to wild-type or knockout mice in the presence or absence of poly (IC), followed by the transfusion of murine RBCs expressing the human KEL glycoprotein. Anti-KEL alloimmunization, serum cytokines, and consumption of the transfused RBCs were evaluated longitudinally. In some experiments, recipients were treated with type 1 IFN (IFN-α/β). Recipient treatment with poly(IC) led to breakthrough anti-KEL alloimmunization despite KELIg administration. Recipient CD4+ T-cells were not required for immunoprophylaxis efficacy at baseline, and modulation of the KEL glycoprotein antigen occurred to the same extent in the presence or absence of recipient inflammation. Under conditions where breakthrough anti-KEL alloimmunization occurred, KEL RBC consumption by inflammatory monocytes and serum MCP-1 and IL-6 were significantly increased. Poly(IC) or type I IFN administration was sufficient to cause breakthrough alloimmunization, with poly(IC) inducing alloimmunization even in the absence of recipient Type I interferon receptors. A better understanding of how recipient antiviral responses lead to breakthrough alloimmunization despite immunoprophylaxis may have translational relevance to instances of RhIg failure that occur in humans.

In plants, RNA and genomic DNA can activate immunity, although the exact mechanism through which they are sensed is not clear. The aim of this work was to study the possible effect of ssODNs on plant immunity. KEY RESULTS ssODNs IMT504 and 2006 increased protection against the pathogens Pseudomonas syringae pv. tomato DC3000 and Botrytis cinerea but not against Tobacco Mosaic Virus - Cg when infiltrated in Arabidopsis thaliana. In addition, ssODNs inhibited root growth and promoted stomatal closure in a dose dependent manner, with half maximal effective concentrations between 0.79 and 2.06 µM. Promotion of stomatal closure by ssODNs was reduced by DNase I treatment. It was also diminished by the NADPH oxidase inhibitor diphenyleneiodonium and by coronatine, a bacterial toxin that inhibits NADPH oxidase-dependent reactive oxygen species (ROS) synthesis in guard cells. RIN1 cost In addition it was found that ssODN-mediated stomatal closure was impaired in bak1-5, bak1-5/bkk1, mpk3 and npr1-3 mutants.
