Differentiating follicular thyroid carcinoma from the follicular variant of papillary thyroid carcinoma
… follicular adenoma (FA), follicular thyroid carcinoma (FTC) and follicular variant of papillary thyroid carcinoma (FVPTC) remain a diagnostic challenge in some cases. This is as a result of the assessment of nuclear features being highly subjective, and the threshold for confirming …

Clinical problems in thyroid surgery
Background: Thyroid surgery is the most common endocrine surgical operation and is considered by many to be at the zenith of endocrine surgery. A good hemostasis is mandatory during a thyroid operation and many new devices have been available during the last two decades. Total thyroidectomy, (TT) …

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 …

Synthesis of novel thyroid hormone analogues
… on the ring may lead to even more potent anti-thyroid drugs.

The role of thyroid hormones in placental development and the importance of the thyroid hormone transporter MCT8
Thyroid hormones (THs) are important for fetoplacental development. Human intrauterine growth restriction (IUGR) is associated with malplacentation and reduced fetal circulating concentration of THs. The expression of the plasma membrane TH transporters MCT8, MCT10, LAT1, LAT2, OATP1A2 and OATP4A1 …

The laboratory assessment of thyroid function with special reference to the importance of thyroid abnormality in psychiatric disease
… the incidence and clinical importance of thyroid abnormalities in an acute psychiatric population and to use such information in the development of a laboratory diagnostic policy for the investigation of such groups. This involved the use of established in vitro assays for serum thyroxine …

Extrathyroidal thyroid hormone activation in ring doves
… observed period of greatest increase in plasma thyroid hormone concentrations during the first 6-8 days posthatch in ring doves. These results are the first demonstration of initial velocity 5’D activity during development in an altricial bird species and demonstrate a correlation between …

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 …

Stimulation of adenylosuccinate synthetase by thyroid hormones
The effect of thyroid hormones on purine biosynthesis was studied in vitro. With 100,000 x g supernatant fraction of rat liver homogenate, the results suggested that thyroid hormones stimulated total purine synthesis from labeled glycine-1-¹⁴C. Further studies indicated that these hormones …

Identifying Metabolic Liabilities in Hürthle Cell Thyroid Carcinoma
… for tumor growth. Hürthle cell carcinoma of the thyroid (HTC) represents an outlier wherein HTC tumors enrich for mitochondrial DNA mutations that are predicted to impair complex I of the electron transport chain (ETC). Consistent with these mutations, our work shows that HTC models harboring …

Regulation of Secretory Phospholipase A2 by Thyroid Hormone
… atherosclerosis. The potential linkage of hypothyroidism with inflammation led us to examine the modulation of sPLA2 expression by thyroid hormone (T3) in liver.</p> <p>Objective: Most of the studies of phospholipase A2 group IIA (PLA2g2a) have been conducted with macrophages and vascular …

The impact of thyroid dysfunction on cardiovascular risk
Thyroid dysfunction syndromes (hypo and hyperthyroidism) have major impacts on the cardiovascular system. Whilst the short term effects of thyroid dysfunction on the cardiovascular system are clinically obvious and well studied, the long term effects and particularly the size of its effects on the …

Thyroid in intestinal development during atlantic salmon smoltification
… to be equipped to accommodate these changes. Thyroid hormones (THs) play an essential role in developing and differentiating the intestine in tadpoles and mammals. They are important in the preparation for new environments, such as the passage from the aquatic to the terrestrial environment in …

Thyroid Status in Exercising Horses and Laminitic Ponies
… to the understanding and assessment of thyroid function in horses. The first study evaluated methods of assessing thyroid function in horses, including validation of an enzyme immunoassay (EIA) for measuring equine thyroid hormones and development and assessment of a thyrotropin …

The response of rat thymus nuclei to thyroid hormones
… affected by L-T₃. These results demonstrate that thyroid hormones modify the chromatin in such a way that the template efficiency is increased. An hypothesis for the mechanism of thyroid hormone action was presented.

Association of autoimmune thyroid disease and type 1 diabetes
Overt autoimmune hyperthyroidism and hypothyroidism were found three times more commonly in insulin-dependent than in non-insulindependent diabetics. Similarly, clinically unrecognised primary autoim¬ mune thyroid failure, as evidenced by elevation of the serum thyrotro¬ phs concentration, was …
