known as L-thyroxine, is a synthetic form of the thyroid hormone thyroxine (T4). It is used to treat thyroid hormone deficiency (hypothyroidism), including...

with blood tests measuring thyroid-stimulating hormone (TSH) and thyroxine (T4) levels. Salt iodization has prevented hypothyroidism in many populations...

TSH levels, many doctors test for T3, Free T3, T4, and/or Free T4 for more detailed results. Free T4 is unbound to any protein in the blood. Adult limits...

another autoimmune disease. Diagnosis is confirmed with blood tests for TSH, T4, and antithyroid autoantibodies. Other conditions that can produce similar...

Danske Statsbaner in 1953 SJ ordered five modified G12 locomotives in 1955 with delivery in 1956. They were originally designated T4, but this was later changed...

phage T4 morphogenesis. The DNA is packed efficiently within the heads. The whole process takes about 15 minutes. Early studies of bactioriophage T4 (1962-1964)...

It was discovered in the late 1970s and was originally known as leu-3 and T4 (after the OKT4 monoclonal antibody that reacted with it) before being named...

tests and radioiodine uptake. Typically, blood tests show a raised T3 and T4, low TSH, increased radioiodine uptake in all areas of the thyroid, and TSI...

certain prions. The genes of bacteriophage (phage) T4 that encode proteins with a role in determining phage T4 structure were identified using conditional lethal...
