3.The physiologically active form of thyroid hormone, T3 or triiodothyronine, has been shown to directly enter cardiomyocytes and alter activity at the level of the genome. 4.The ratio of thyroxine to triiodothyronine in humans is about 80:201. ...
The thyroid hormone (TH)-controlled recruitment process of brown adipose tissue (BAT) is not fully understood. Here, we show that long-term treatment of T3, the active form of TH, increases the recruitment of thermogenic capacity in interscapular BAT of
The principal tests used in the laboratory evaluation of thyroid function are Total Thyroxin (T4), Total Triiodothyronine (T3), T- Uptake (T-Up), a calculated Free Thyroxin Index (FTI) and Thyroid Stimulating Hormone (TSH). The results of these tests are interrelated and help the clinician ...
However, the normal thyroid gland produces a small proportion of triiodothyronine (T3) directly into the circulation. Aim We aimed to study the free T3 to free T4 ratio in treated central hypothyroidism compared with euthyroidism and treated primary hypothyroidism. Methods Eighty-three subjects were ...

We examined the relationship between free T3 (FT3) and free thyroxine (FT4) levels in the first 7 d and the primary outcome death or ventilator dependence at 1 wk in all 253 babies. We found significant positive correlations of p ϭ 0.05 for FT3 and p ϭ 0.002 for FT4. Thus the ...
of urea cycle enzyme activities, substrate levels or the levels of urea cycle intermediates on urea production was investigated in a set of four experiments in which rats were fed a diet supplemented with 6-propyl-2-thiouracil (PTU, a thyroid inhibitor) and treated with triiodothyronine (T3)....
Figure 4. De novo T3 formation in TG secreted from the PCCL3 rat thyrocyte cell line. A, TG secreted into serum-free media bathing control PCCL3 was iodinated in vitro, or non-iodinated as a negative control. The samples were analyzed by SDS-PAGE (2 μg of protein/lane), electrotra...
Serum levels of thyroid hormones (triiodothyronine [T3], reverse T3, free thyroxine [T4], and thyroid-stimulating hormone) were measured in 331 consecutive patients with acute myocardial infarction (mean age [± SD], 68 ± 12 years), from samples obtained at the time of admission. Results Fif...
