The mass spectral properties of four classes of derivatives of thyronine are discussed ( oxazolidinone , O-methyl oxazolidinone , O-acetyl oxazolidinone and N,O- diheptafluorobutyryl methyl ester). An assay for thyronine in human urine is described based on the N,O- diheptafluorobutyryl

A highly sensitive, specific, and reproducible RIA has been developed to measure T3 sulfate (T3S). Only T4 sulfate cross-reacted significantly (approximately 3%) in the RIA; rT3 sulfate, T4, T3, rT3, and diiodothyronine cross-reacted less than 0.01%. T3S was bound by

Thyroid hormones control growth, development, differentiation and metabolism in vertebrates. Most of the actions of the active thyroid hormone T3 (3,5,3'-triiodo-L-thyronine) are exerted via ligand-activated nuclear T3 receptors. Activation of the secretory product of the thyroid gland, L-thyroxine (3,3',5,5'-tetraiodo-L-thyronine), or

A hidden pool of rT3 production represents a source of rT3 that is minimally reflected in circulating rT3 levels. To test for the existence of such a source of rT3 production in man, varying doses of the generalized deiodinase inhibitor

Oligodendrocyte precursor cells (OPCs) are glial cells that differentiate into oligodendrocytes and myelinate axons. The number of OPCs is reportedly increased in brain lesions in some demyelinating diseases and during ischemia; however, these cells also secrete cytokines and elicit both
