Introduction: Extraosseous accumulation of 99mTc – methylene diphosphonate (MDP) may be due to neoplastic, dystrophic, hormonal, inflammatory, ischemic, traumatic or excretory disorders. 99mTc-MDP incidental thyroid uptake is not frequent and is possibly caused by the presence of dystrophic or metastatic calcification, biopsy procedure and presence of beni...

The interaction of immunological system, thyroid and pineal gland was studied in 5-week old males of Gallus domesticus. Several morphometrical parameters in pineal and thyroid glands were measured after bird immunization with human red blood cells and/or treatment with melatonin or seduxen, melatonin receptor blocker. The peak of the thyroid activity was found on Day 7 after immunization. The i...

Ectopic thyroid is a congenital defect in which the thyroid gland is located away from the usual pretracheal location. Dual ectopic thyroid, which consists of two foci of thyroid tissue, is very rare. In this case dual ectopic thyroid with subclinical hypothyroidism in a 10-year-old-girl was reported. The absence of the thyroid gland in the pretracheal location was revealed by ultrasonography (...

The name thyroid gland, in English, is derived from the Latin glandula thyreoidea, meaning shield-shaped gland, named by Thomas Warton in 1656 [1]. As the first endocrine gland to develop embryologically [2], it possesses important functions from fetal development until death. Embryologically, the development of the thyroid gland begins in the fourth week of development as a depression and epit...

to produce the thyroid hormones T3 and T4, which regulate gene transcription throughout the body (1). In medical practice, the thyroid becomes an issue when its size or shape becomes abnormal or when it produces too much or too little hormone. Thus, we typically think of the thyroid with reference to the clinical states of goiter, or hyper-or hypothy-roidism. But what is the physiology of the t...

BACKGROUND፡ The thyroid, along with the breast, lung, and bone marrow, is among most radiosensitive organs. This study aims to assess rate of unnecessary radiation exposure thyroid gland in patients who had chest Computed Tomography (CT) at a large teaching hospital. 
 METHOD: Hospital-based retrospective cross-sectional on 1,306 underwent CT from July 2018 January 2019. Thyroid inclusion ...

MATHEMATICAL MODELING AND DYNAMICAL ANALYSIS OF THE OPERATION OF THE HYPOTHALAMUS – PITUITARY – THYROID (HPT) AXIS IN AUTOIMMUNE (HASHIMOTO’S) THYROIDITIS Balamurugan Pandiyan, B.S., M.S. Marquette University, 2011 This thesis is a mathematical modeling study of the operation of the negative feedback control through the hypothalamus-pituitarythyroid (HPT) axis in autoimmune (Hashimoto’s) thyroi...

The following conclusions may be drawn from the experiments presented in this article. 1. Excessive meat diet develops hypertrophy of the thyroid gland. A definite hypertrophy of the parathyroid gland under the same conditions has not been established. A meat diet does not develop hypertrophy of the thyroid gland when insufficiency of the parathyroid gland exists at the same time, even if no cl...

colorectal cancer (crc) metastasis to the thyroid gland is rare. here wereport a 45 yr-old man in western iran referred to hematology clinic, kermanshah city, iran in march 2014 with complaint of exertional dyspnea, multi-nodular goiter as well as complaint of exertional dyspnea, and multi-nodular goiter. his history included a low anterior resection of rectum in 9 months ago for a high-risk st...
