RECENT experimental observations in animals have indicated that certain modifications of the chemical structure of the natural thyroid hormones, L-thyroxine and L-tri-iodothyronine, result in ...

Hypothyroidism during pregnancy has been associated with impaired cognitive development and increased fetal mortality. During pregnancy, maternal thyroid hormone requirements increase. Although it is ...

New research shows that it may be safe for patients taking thyroxine replacement to have low but not suppressed thyroid stimulating hormone (TSH) levels. The research shows for the first time that it ...

ALTHOUGH much of the progress in thyroid hormone biochemistry is due to the use of thyroxine and 3 : 5 : 3′-triiodothyronine labelled with iodine-131, the high metabolic lability of the iodine atoms ...
