Originally developed as research tools, different classification criteria sets for systemic lupus erythematosus (SLE) are also used to diagnose SLE in routine clinical care. The recently developed European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) 2019 criteria set is noted to perform better than previous SLE classification criteria. This study applied the new criteria schema to a tertiary center SLE cohort, ascertained its performance, and identified the clinical characteristics of patients who did not fulfill these criteria. From the 217 patients who were included, 11 (5%) did not meet the new criteria, mainly because of the antinuclear antibody entry criterion, resulting in a diagnostic sensitivity of 94%. Within this group, we found that constitutional and renal manifestations were unusual. Additionally, specific SLE antibodies as well as hypocomplementemia were less likely to be present. We did not observe a statistically significant difference in outcomes between the two groups of patients (fulfilling vs. unfulfilling the new criteria). We conclude that the EULAR/ACR criteria may misclassify a small subset of SLE patients with milder disease. It is important to be cognizant of key clinical and serologic features of these patients and treat them accordingly to prevent further irreversible damage.In addition to their role in hemostasis and coagulation platelets bear critical roles in modulation of the innate and adaptive immune system. Upon platelet activation in response to tissue injury, bacterial or viral infections, they secrete many soluble factors or directly interact with leukocytes. An increase of leukocyte-platelet aggregates (LPA) has been described for many pathological conditions. Nevertheless, a standardized method for the reliable measurement of PLAs is not securely established. This methodical study provides a comparison of four different protocols from the literature and summarizes major pitfalls of measuring and interpreting leukocyte-platelet aggregates. The different techniques vary in the workup of the blood samples, applying variable washing and centrifugation steps or the use of erythrocyte lysis. All samples were finally analyzed by flow cytometry. Leukocyte subsets were stained with specific antibodies and platelet aggregates were identified by additional expression of CD41. The different procedures generated very heterogeneous data from the same blood sample which highlight the abundance of error measuring LPA. The most reproducible technique turned out to be a two-color whole blood flow cytometry assay with erythrocyte lysis and without washing or centrifugation steps avoiding platelet activation and artificial aggregate formation to achieve data mirroring the true situation in peripheral blood.INTRODUCTION Veno-arterial extracorporeal membrane oxygenation is a valuable therapeutic approach in patients with severe heart failure due to different etiologies. Current prognosis with veno-arterial extracorporeal membrane oxygenation is unsatisfactory, and the risk stratification is still challenging. Therefore, we aimed to evaluate the predictive value of different baseline model for end-stage liver disease scores for survival in patients with veno-arterial extracorporeal membrane oxygenation. METHODS We conducted an observational, retrospective study of consecutive veno-arterial extracorporeal membrane oxygenation-treated patients between January 2012 and August 2018. The four types of model for end-stage liver disease scores-model for end-stage liver disease, international normalized ratio-excluded model for end-stage liver disease, modified model for end-stage liver disease, and model for end-stage liver disease with sodium-were calculated preoperatively. Veno-arterial extracorporeal membrane oxygenatdence interval = 1.01-1.06; p = 0.006), and model for end-stage liver disease with sodium (hazard ratio = 1.05; 95% confidence interval = 1.02-1.08; p = 0.001). learn more CONCLUSION Model for end-stage liver disease, modified model for end-stage liver disease, and model for end-stage liver disease with sodium scores could be useful in the risk stratification of veno-arterial extracorporeal membrane oxygenation treatment in varying clinical indications.An endless drug-resistant strains of Helicobacter pylori and multitudinous drug reactions are obstacles in the treatment of H. pylori infections, thereby ambitious novel proof-of-concept for inhibitor design was practiced in advancement of medication. Dihydropteroate synthase (DHPS) is an alluring target that plays a great role in folate synthesis pathway essential for amino acids biosynthesis was selected for designing novel drugs to prevent infections caused by pathogenic H. pylori. In the present study, a reliable tertiary structure of DHPS in complex with inhibitor 6MB was constructed by Modeler 9v19. DrugBank compounds of DHPS, published inhibitors, and co-crystal ligand (6MB) were docked against DHPS. The best docked compounds were screened against 28.5 million compounds resulted 1186 structural analogs. Virtual screening workflow and quantum polarized ligand dockings of these compounds against DHPS resulted three leads that showed better XP Gscores, ADME properties, and binding-free energies compared to 6MB, DrugBank compounds, and published inhibitors. The proposed leads were also validated by receiver operative characteristic (ROC) curve metrics in the presence of thousand decoys and the best docked existing compounds against DHPS. Long-range molecular dynamics (MD) simulations for 100 ns were executed after post-docking evaluations. Trajectory analysis showed the lead-DHPS docking complex's inter-molecular interactions were stable throughout the entire runtime of MD simulations than 6MB-DHPS complex and Eliglustat-DHPS complex. The study outcomes showed good competitive binding propensity and active-tunneling of leads over the existing inhibitors, thereby these leads could be ideal inhibitors against DHPS to target H. pylori.The aim of the present research was to investigate the feasibility of developing polylactide-polycaprolactone-polyethylene glycol-polycaprolactone-polylactide (PLA-PCL-PEG-PCL-PLA) based micelles to improve ocular permeability of dexamethasone (DEX). PLA-PCL-PEG-PCL-PLA copolymers were synthesized by a ring-opening polymerization method. DEX was loaded into the developed copolymers. The DEX-loaded micelles were characterized using transmission electron microscopy (TEM) and dynamic light scattering (DLS) methods. Cytotoxicity of the micelles obtained was investigated on L929 cell line. Cellular uptake was followed by fluorescence microscopy and flow cytometry analyses. The release behavior of DEX from the micelles as well as the drug release kinetics was studied. Corneal permeability was also evaluated using an ex vivo bovine model. The pentablock copolymers were successfully synthesized. The TEM results verified the formation of spherical micelles, the sizes of which was approximately 65 nm. The micelles exhibited suitable compatibility on L929 cells.
