Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
Autoimmune polyendocrine syndrome type 2, a form of autoimmune polyendocrine syndrome also known as APS-II, or PAS II, is the most common form of the polyglandular failure syndromes. [2] PAS II is defined as the association between autoimmune Addison's disease and either autoimmune thyroid disease , type 1 diabetes , or both. [ 5 ]
10% (UK) [ 3] An autoimmune disease is a condition that results from an anomalous response of the adaptive immune system, wherein it mistakenly targets and attacks healthy, functioning parts of the body as if they were foreign organisms. [ 1] It is estimated that there are more than 80 recognized autoimmune diseases, with recent scientific ...
Iodothyronine deiodinase. Iodothyronine deiodinases ( EC 1.21.99.4 and EC 1.21.99.3) are a subfamily of deiodinase enzymes important in the activation and deactivation of thyroid hormones. Thyroxine (T 4 ), the precursor of 3,5,3'- triiodothyronine (T 3) is transformed into T 3 by deiodinase activity. T 3, through binding a nuclear thyroid ...
T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and will cause the disease known as simple goitre. [3] The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week [4] is longer than that ...
Heat intolerance is a symptom characterized by feeling overheated in warm environments or when the surrounding environment's temperature rises. [ 1] Typically, the person feels uncomfortably hot and sweats excessively. Compared to heat illnesses like heatstroke, heat intolerance is usually a symptom of endocrine disorders, drugs, or other ...
Extreme heat (and extreme cold) can significantly alter the effectiveness of prescription and over-the-counter drugs. Some medications can tolerate temperatures up to 86 degrees Fahrenheit (30 ...
Type IV hypersensitivity, in the Gell and Coombs classification of allergic reactions, often called delayed-type hypersensitivity, is a type of hypersensitivity reaction that can take a day or more to develop. [ 1] Unlike the other types, it is not humoral (not antibody -mediated) but rather is a type of cell-mediated response.
