Background: Despite sensitivity of MRI to diagnose multiple sclerosis (MS), prognostic biomarkers are still needed for optimized treatment. Objective: The objective this paper is identify cerebrospinal fluid (CSF) diagnostic MS using quantitative proteomics and analyze their expression at different disease stages.

Objective To estimate sacroiliac joint radiographic (X-SIJ) progression in patients with axial spondyloarthritis (axSpA) and to evaluate the effects of inflammation on MRI (MRI-SIJ) X-SIJ progression. Methods MRI-SIJ at baseline after 2 5 years recent onset axSpA from DESIR cohort were scored by three central readers. Progression was defined as (1) shift non-radiographic (nr) (r) sacroiliitis (by modified New York (mNY) criteria) or alternative criteria, (2) a change least one grade (3) but...

Background: NETosis occurs in the context of infection or inflammation and results expulsion decondensed DNA filaments called NETs (Neutrophil Extracellular Traps) into extracellular environment. activates coagulation contributes to thrombotic risk inflammatory diseases. To date, two mechanisms have been identified: suicidal NETosis, which neutrophils die after expelling filaments; vital appears without altering membrane. Human pregnancy is associated with a mild pro-inflammatory state,...
