background: the physiological changes in thyroid gland during pregnancy have been suggested as one of the pathophysiologic causes of preeclampsia. objective: the aim of this study was comparison of serum levels of tri?iodothyronine (t3), thyroxine (t4), and thyroid?stimulating hormone (tsh) in preeclampsia and normal pregnancy. materials and methods: in this case?control study, 40 normal pregna...

Stimulation of the thyroid with thyroid-stimulating hormone (TSH) is a potentially useful diagnostic dysfunction, but little known about response to TSH stimulation in bottlenose dolphins (Tursiops truncatus). To better characterize dolphin stimulation, five adult participated study. Dolphins voluntarily beached onto padded mat and were given 1.5 mg intramuscular injection human recombinant TSH...

background beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. the purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. materials and methods this descriptive-cross sectional study was performed on 90 children aged 6-16 yea...

Thyroid stimulating hormone (TSH) is one of the key indicators in diagnosis thyroid gland functional disorders. Minor changes TSH concentration make it possible to suspect dysfunction even before clinical manifestations, which increases value correct and timely measurement it. In practice, an endocrinologist often encounter well-known phenomenon macroprolactinemia; a much less common macrotyrot...

Aim: To find out association of Serum Thyroid Stimulating Hormone (TSH) and Anti-Thyroid Antibodies (ATA) i.e., anti Tg-Ab & TPO-Ab with thyroid carcinoma in nodule patients presented Mayo Hospital Lahore. Study design: It was a comparative cross-sectional study. Methods: wasconducted Biochemistry Department Biomedical Sciences KEMU, Lahore from February 2018 to May 2019. Seventy were inclu...

Thyroid hormone (T3 and T4) is secreted from the thyroid gland, and is known to reduce the level of serum thyrotropin (thyroid-stimulating hormone, TSH) in the pituitary gland (Sarapura et al., 2002; Shupnik et al., 1989) (Fig. 1A). This is a typical example of negative feedback between the pituitary and endocrine organs, and is a key component of thyroid hormone homeostasis. TSH is one of the ...

The effect of graded exercise on the secretion of cortisol, testosterone, prolactin, growth hormone, thyroid stimulating hormone (TSH), luteinizing hormone and follicle stimulating hormone (FSH) is reported. While cortisol, prolactin, growth hormone and testosterone rise during the period of exercise, a rise in luteinizing hormone becomes evident only after rest. Levels of FSH and TSH remained ...

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 determination of serum or plasma levels of thyroid stimulating hormone (TSH or thyrotropin) is recognized as a sensitive method in the diagnosis of primary and secondary hypothyroidism.1 TSH is secreted by the anterior lobe of the pituitary gland and induces the production and release of thyroxine and triiodothyronine from the thyroid gland.2 It is a glycoprotein with a molecular weight of ...
