ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.

Abstract Background Microscopic colitis (MC) typically presents with chronic, non‐bloody watery diarrhea. Diagnosis requires endoscopy with colonic mucosal biopsies. The etiology is multifactorial, with several medications implicated, although only a few cases have been attributed to oral levodopa/dopa‐decarboxylase inhibitor (LDDCI) therapy.

Limited tryptic proteolysis of pig kidney 3,4-dihydroxyphenylalanine decarboxylase
Pig kidney 3,4-dihydroxyphenylalanine (Dopa) decarboxylase can be nicked by trypsin with complete loss of its catalytic activity. The original dimer of subunit molecular weight of about 52,000 yields fragments of Mr 38,000 and 14,000, as seen on sodium ...

Abstract Background Variants in AFG3‐Like Matrix AAA Peptidase, Subunit 2 (AFG3L2) gene are associated with diverse clinical phenotypes. Here, we describe phenotypic findings of two unrelated children with de novo heterozygous variant and one family with inherited heterozygous variant in AFG3L2 gene.
