The disruption mechanisms of oxidative stress include oxidative damage to cellular components (protein oxidation, lipid peroxidation, and DNA damage), activation of matrix metalloproteinases, cytoskeleton reorganization, modulation of tight junction proteins, and upregulation of inflammatory mediators [81, 86, 87]
Endotoxin testing (USP , the Bacterial Endotoxins Test) is a separate assay from sterility testing and catches a class of contamination that sterility testing alone misses
The rat studies producing the cardiovascular effects described above used 2 to 10 mcg/kg/day, which in a 70 kg adult would correspond to roughly 140 to 700 mcg/day, providing some rough allometric alignment with compounded doses but not a validated human dose
