Thyroid disease often causes menstrual disturbances and infertility problems. Thyroid hormone (TH) acts through its receptors, transcription factors present in most cell types in the body. Thyroid stimulating hormone (TSH) stimulates TH synthesis in the thyroid gland, but seems to have other functions as well in the female reproductive tract. The receptors of both TH and TSH increase in the rec...
The activity of the thyroid gland is predominantly regulated by the concentration of the pituitary glycoprotein hormone, thyroid stimulating hormone (TSH). In the absence of pituitary or of thyrotroph function hypothyroidism ensues. Thus, regulation of thyroid function in normal individuals is to a large extent determined by the factors which regulate the synthesis and secretion of TSH. Those f...
Thyroid-stimulating hormone (TSH) increased within 1 mm the adenyl cyclase activity of bovine and canine thyroid homogenate. A similar effect was also found when adenyl cyclase activity was measured in thyroid slices. In experiments in vivo, adenyl cyclase activity was augmented within 3 min after TSH injection, but this effect did not persist for 60 min after the injection. Despite the transie...
Transient hypothyroxinemia in infants born to mothers with poorly controlled Graves' disease was first reported in 1988. We report that short-term hyperthyroidism followed by hypothyroidism with low basal thyroid-stimulating hormone (TSH) levels developed in a very low birth weight infant born at 27 weeks of gestation to a noncompliant mother with thyrotoxicosis attributable to Graves' disease....
Few studies have included subjects with the propensity to reach old age in good health, with the aim to disentangle mechanisms contributing to staying healthier for longer. The hypothalamic-pituitary-thyroid (HPT) axis maintains circulating levels of thyroid stimulating hormone (TSH) and thyroid hormone (TH) in an inverse relationship. Greater longevity has been associated with higher TSH and l...
the ideal approach for adequate management of subclinical hyperthyroidism (low levels of thyroid-stimulating hormone [tsh] and normal thyroid hormone level) is a matter of intense debate among endocrinologists. the prevalence of low serum tsh levels ranges between 0.5% in children and 15% in the elderly population. mild subclinical hyperthyroidism is more common than severe subclinical hyperthy...
Abstract Background and Objectives: The hyperthyroidism, caused in Pregnancy, may Leads to nausea and vomiting. The aim of this study was to establish the relationship between the serum thyroid stimulating hormone (TSH) and thyroxin. (T4), which reflect thyroid function assessment, with nausea and vomiting, among pregnant women in early pregnancy. Material and Methods: the Subjects of this Case...
Background: Depression is one of the most common psychiatric disorders with substantial morbidity and mortality. It known to be associated changes in hypothalamic-pituitary-thyroid axis, thus may accompanied by subtle thyroid dysfunction. Thus, our study aims determine prevalence characteristics dysfunction newly diagnosed depressive patients. Materials Methods: A prospective descriptive cross ...
Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...
