Appropriate thyroid gland function and thyroid hormone activity are considered crucial to sustain the productive performance in domestic animals (growth, milk or hair fibre production). Changes of blood thyroid hormone concentrations are an indirect measure of the changes in thyroid gland activity and circulating thyroid hormones can be considered as indicators of the metabolic and nutritional ...

Thyrotropin stimulates the incorporation of 32P into phospholipids of thyroid slices incubated with 32P04. To determine whether this effect could be secondary merely to an increase in the specific activity of the terminal (y) P of ATP, a precursor of phospholipid P, the effect of thyrotropin on calf thyroid slice ATP was measured with an assay which is selective for ATP-T-~~P specific activity....

Peroxidase activities of autonomously functioning thyroid tumors (T) and surrounding non-tumorous tissue (N) in 5 patients were determined by employing guaiacol or iodide as the second substrates. The mean values for specific activities of T were 30 times (in iodide oxidation assay) or 4 times (in guaiacol oxidation assay) as high as those in N, being significantly higher than those of non-func...

BACKGROUND Radioactive iodine is commonly administered following thyroidectomy for differentiated thyroid carcinoma to ablate the thyroid remnant. The optimal administered activity of radioiodine is unknown. METHODOLOGY/PRINCIPAL FINDINGS Adult subjects (n = 160) diagnosed with papillary or follicular thyroid carcinoma were randomly allocated to receive either 1100 MBq (30 mCi) or 3700 MBq (1...

The homeobox-containing gene Hex is expressed in several cell types, including thyroid follicular cells, in which it regulates the transcription of tissue- specific genes. In this study the regulation of Hex promoter activity was investigated. Using co- transfection experiments, we demonstrated that the transcriptional activity of the Hex gene promoter in rat thyroid FRTL-5 cells is approximate...

we determined the frequency of clinical thyroid ophthalmopathy in iranian patients. this cross-sectional study was performed at the endocrinology institute of tehran university of medical sciences. all patients with documented thyroid disorders from september 2003 to july 2005 were recruited. eye examinations included evaluation of soft tissue changes, measurement of proptosis, lid width, lagop...
