Ability to predict rheumatoid arthritis relapse after tumour necrosis factor inhibitor tapering by the Multi-Biomarker Disease Activity Score: a post-hoc analysis of the STRASS trial.

Objectives: The aim was to evaluate the ability of baseline multi-biomarker disease activity (MBDA) score to discriminate between patients with rheumatoid arthritis (RA) in remission who are at high risk versus low risk of relapse after TNF-inhibitor (TNFi) tapering.

Methods: The study is a post-hoc analysis of patients who completed the Spacing of TNFi injections in Rheumatoid ArthritiS Study (STRASS), a multicentre 18-month equivalence randomised controlled study, of TNFi tapering in RA patients in remission, and had baseline serum samples available for MBDA testing. The primary endpoint of this study was the ability of the baseline MBDA score to predict relapse at any time during the 18 months following initiation of TNFi tapering.

Aggressive PDACs Show Hypomethylation of Repetitive Elements and the Execution of an Intrinsic IFN Program Linked to a Ductal Cell of Origin.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by extensive desmoplasia, which challenges the molecular analyses of bulk tumor samples. Here we FACS-purified epithelial cells from human PDAC and normal pancreas and derived their genome-wide transcriptome and DNA methylome landscapes. Clustering based on DNA methylation revealed two distinct PDAC groups displaying different methylation patterns at regions encoding repeat elements.

Raman scattering and red emission of Mn in LaSrNaMnTiO manganite phosphor for LED applications.

The vibrational and optical properties of an LaSrNaMnTiO (LSNMT) polycrystalline sample produced a solid-state reaction were studied. The Raman spectrum at room temperature reveals the chemical disorder in our compound. The optical gap and Urbach energy were estimated on the basis of the absorption spectrum.

Study of diffuse phase transition and relaxor ferroelectric behavior of BaBiTiZrNbO ceramic.

In the present work, structural and dielectrics properties of polycrystalline sample BaBiTiZrNbO (BBTZN) prepared by a molten-salt method were investigated. X-ray diffraction analyses revealed the formation of a single-phase pseudocubic structure with a 3̄ space group. Unlike the trend observed in classic ferroelectrics, the temperature dependence of the dielectric constants showed the presence of three sequences of structural phase transitions.
