The simultaneous determination of 6-methoxy-2-naphthylacetic acid (6MNA) and diflunisal in serum samples using the combination of matrix isopotential synchronous fluorescence (MISF) and first derivative technique is proposed. 6MNA and diflunisal exhibit overlapped spectra and serum produces background fluorescence that precludes

Amyloid : the international journal of experimental and clinical investigation : the official journal of the International Society of Amyloidosis, 19 Suppl 1, 37-38 (2012-05-04)
Familial amyloidotic polyneuropathy (FAP) is a protein folding disorder that induces neuropathy and cardiomyopathy, leading to death within 7-15 years after onset of clinical disease. In vitro, small ligands binding the thyroid hormone docking site stabilize tetrameric transthyretin, inhibiting amyloid
