Studies in the biosynthesis of the hormones of the thyroid gland.
… in order to elucidate two important problems in Thyroid Biochemistry namely, the kinetics of labelling of tyrosine and monoiodotyrosine (MIT) and the pathways of synthesis of triiodothyronine (T3 ) and thyroxine (T4 ).

Morphological imaging of the canine thyroid gland with an application towards hypothyroid dogs
… echografisch waargenomen in een populatie hypothyroIde honden: hypoechogeen en heterogeen parenchym, onregelmatige aflijning van het kapsel, ronde vorm van de schildklierlob op dwarsdoorsnede en verkleind schildklier volume. De vijf parameters gecombineerd, resulteerde in een sensitiviteit van …

Morphometric changes in the prepubertal rat thyroid gland following acute exposure to PCBs
… further used to examine the effects of PCBs on thyroid glands through examination of serum thyroxine (T$\sb4$) and morphometry.

Radiobiological effects of the thyroid gland - transcriptomic and proteomic responses to 131l and 211At exposure
… targeting molecules or as halide to target the thyroid or thyroid cancer. 211At is proposed for radionuclide therapy and preclinical and clinical research on 211At-labeled tumor targeting molecules is on-going. The thyroid gland accumulates both 131I and 211At as halides and is an organ at risk. …

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 …

Morphologische Grundlagen der Schilddrüsensonographie bei der Katze
… for the sonographic examination of the feline thyroid gland The thyroid glands of 101 deceased cats were removed for morphological, sonographical, morphometrical, volumetrical and pathohistological assessment to investigate the morphological fundamentals for sonographic examination. The …

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 …

Microdosimetry of radiohalogens in thyroid models
… models both for tumours and normal tissues. The thyroid gland has shown a high uptake of radioiodide and free 211At and is, therefore, considered as an organ at risk. It is thus critical to be able to accurately calculate the absorbed dose in the thyroid. Accurate dosimetry is also important for …

Der diagnostische Stellenwert der MIB-1- und PCNA-Immunhistometrie in der Differentialdiagnostik follikulärer Schilddrüsentumoren
… diagnosis of follicular tumors of the thyroid gland The cellular prolifarative activity MIB-1 and PCNA immunopositivity of normal tissue (n = 30), follicular adenoma (n = 21) and follicular carcinoma (n = 28) of the thyroid gland was analysed by means of immunohistometry. …

Το υπερηχογράφημα στη μη τοξική βρογχοκήλη: Κλινικές και υπερηχογραφικές παρατηρήσεις προ και μετά θεραπευτικές παρεμβάσεις με θυρεοειδικές ορμόνες
The findings from the physical examination of the thyroid gland, of 237 patients with non toxic goiter, (weight, number and dimensions of nodes etc) were compared with the findings. From the ultra-sound examination before and after suppressive treatment. Our purpose was to consider the efficiency …

Der humane Natrium-Jodid-Symporter (hNIS) : Entwicklung einer Methode zur Quantifizierung der hNIS-mRNA-Expression und Analyse der Rolle als Antigen bei autoimmunen Schilddrüsenerkrankungen
… is the key molecule for iodide uptake into the thyroid gland. Iodide is essential for the biosynthesis of the thyroid hormones T3 and T4. The symporter is localized at the basolateral membrane of thyroid follicular cells and transports iodide against its electrochemical gradient into the …

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 …
