Quantitative Pertechnetate Thyroid Scintigraphy and the Ultrasonographic Appearance of the Thyroid Gland in Clinically Normal Horses
… scintigraphic and sonographic appearance of the thyroid gland in clinically normal horses so these modalities could be used to assess the thyroid gland in this species. Horses were divided into two age groups. Group A consisted of 8 horses between 3 and 10 years of age and Group B of 7 horses …

The Role of The Thyroid Gland in Regulating Synthesis and Release of Luteinizing Hormone in The Rat
The effects of thyroidectomy and thyroxine (T(,4)) therapy on the synthesis and release of luteinizing hormone (LH) by the anterior pituitary gland (AP) of ovariectomized (Ovx) rats were investigated. Immediately after ovariectomy, rats were thyroidectomized (Tx) or sham-Tx. Starting thirty days …

In vivo and ex vivo techniques using elastic scattering spectroscopy for diagnosis of malignancy in the thyroid gland
OBJECTIVE: Thyroid cancer is the most common endocrine malignancy and patients presenting with thyroid nodules often undergo surgery solely for diagnostic purposes. The goal of our study was to examine the accuracy of Elastic Scattering Spectroscopy (ESS) in distinguishing between benign and …

Does thyroid sparing total laryngectomy decrease the risk of hypothyroidism?
Introduction Thyroid lobectomy is recommended with total laryngectomy for laryngeal cancer in the National Comprehensive Cancer Network (NCCN) guidelines. However, it is associated with a 32-89% risk of hypothyroidism, which represents a problem especially for patients without access to thyroid …

Effects of ammonium perchlorate exposure on the thyroid function and the expression of thyroid-responsive genes in Japanese quail embryos and post hatch chicks
Perchlorate ion interferes with thyroid function by competitively inhibiting the sodium-iodide symporter, thus blocking iodide uptake into the thyroid gland. In this study, the effect of perchlorate exposure on thyroid function and thyroid-responsive gene expression were examined in (1) embryos …

Maternal thyroid hormones in Japanese quail eggs
Thyroid hormone content in eggs varies with the thyroid status of the hen and may influence embryonic development prior to the release of appreciable amounts of thyroid hormones by the embryonic thyroid gland. Methods for the measurement of thyroid hormones in egg yolk were verified by …
