Thyroid hormone acts on a wide range of tissues. In the cardiovascular system, thyroid hormone is an important regulator of cardiac function and cardiovascular hemodynamics. Although some early reports in the literature suggested an unknown extrathyroidal source of thyroid hormone, it is currently thought to be produced exclusively in the thyroid gland, a highly specialized organ with the sole ...
Many synthetic chemicals have been identified as environmental contaminants with activity to disrupt normal function of the thyroid hormone system. Thyroid hormones play important roles in growth, development, differentiation, and basal metabolic homeostasis, as well as in brain development in human fetus and children, and thyroid dysfunction can have very serious consequences, including mental...
OBJECTIVE: Diabetes mellitus and thyroid disease are the two common endocrinopathies seen in adult population. Studies to evaluate thyroid disorders in patients with type 2 diabetes are lacking. The aim of this study was to compare prevalence of thyroid dysfunction and autoim-munity in type 2 diabetic patients with age and sex matched non-diabetic control group. MATERIAL AND METHODS: Among pat...
Polychlorinated biphenyls (PCBs) are well known to reduce the concentrations of thyroid hormones in the circulation of experimental animals (Bastomsky et al., 1976; Brouwer et al., 1998). Moreover, circulating levels of PCBs have been reported to co-vary with various measures of thyroid status in humans (Koopman-Esseboom et al., 1997; Osius et al., 1999). These observations form the basis for t...
Purpose: The association of thyroid related diseases and sex hormones with breast cancer (BC) is reported inconclusive results. 
 Objectives: study was designed to analyze the thyroid/sex hormone ratios BC patients. Methodology: TSH, T3, T4, estrogen, progesterone testosterone concentrations newly diagnosed patients (n=155) aged 30 75 years age-matched normal controls (n=75) were analyzed....
case presentation a 28-year old chinese female was treated with carbimazole (cmz) for graves’ disease with hyperthyroidism. two weeks later, she developed myalgia and proximal muscle weakness. investigations showed evidence of myopathy. cmz was stopped and rapid improvement of clinical condition and biochemical parameters ensued. conclusions rapid decrement of thyroid hormone level is recognize...
Background and Aims: 25-hydroxy vitamin D3 is recognized to be an essential element for healthy body; however, its deficiency has been identified as a risk factor for thyroid disease, diabetes mellitus and other autoimmune diseases and infectious diseases. Thyroid disease is common in the general population that its prevalence increases proportional to age. Subjects with poorly controlled diabe...
Thyroid hormone, operating through its receptors, plays crucial roles in the control of normal human physiology and development; deviations from the norm can give rise to disease. Clinical endocrinologists often must confront and correct the consequences of inappropriately high or low thyroid hormone synthesis. Although more rare, disruptions in thyroid hormone endocrinology due to aberrations ...
The lipolytic activity of bovine thyroid-stimulating hormone and its subunits have been compared to the lipolytic activity of ovine-luteinizing hormone and its subunits. When tested on white adipocytes isolated from epididymal fat pads of BALB/c mice, thyroid-stimulating hormone was a potent lipolytic agent, active at a concentration of 7 X lo-lo M. In contrast, the isolated subunits of thyroid...
Thyroid hormone resistance (THR) is a dominantly inherited syndrome characterized by reduced sensitivity to thyroid hormones. It is usually caused by mutations in the thyroid hormone receptor beta (THRB) gene. In the present report, we describe the clinical and laboratory characteristics and genetic analysis of patients with a novel THRB gene mutation. The index patient had been misdiagnosed as...
