Elevated Liver Enzymes Is Not an Impediment to Allopurinol Dose Escalation: An Observational Cohort Study

Arthritis Care &Research, EarlyView.
Objective Routine liver enzyme monitoring is advocated for while on allopurinol, but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzyme levels in patients with gout commenced on allopurinol. Methods One hundred and fifty patients with gout and normal baseline serum aminotransferases initiated on ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
