Arthritis Care &Research, EarlyView.Objective We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analyzed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalized with AMI between 2005 and 2019 from the Myocardial Ischaemia ...

Partial Discharge Pulse Sequence Analyses-A New Representation of Partial Discharge Data
11th International Symposium on High-Voltage Engineering (ISH 99), 1999 Computer-based partial discharge (PD) data acquisition and analyses are common in use. Over the last two decades, there has been tremendous growth in PD data processing to extract information. There are efforts made to make data banks of different PD signature patterns based on $\phi-q-n$ measurements on insulation models.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution
Advanced Engineering Materials, EarlyView.Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability
