The article examines the cause of low thyroid-stimulating hormone (TSH) level with a normal free T4 level. The decrease TSH level seen in subclinical hyperthyroidism is caused by the pituitary's response to minor elevations in serum or tissue T4 and T3 levels. In the evaluation and treatment ...
TSI (thyroid-stimulating immunoglobulin or TRAb (thyrotropin receptor antibodies): antibodies often found in the blood when Graves’ disease is the cause of hyperthyroidism.Radioactive iodine uptake (RAIU): a measurement of how much iodine the thyroid gland can collect, and thyroid scan, which ...
T4 by RIA (radioimmunoassay) is the most used thyroid test of all. It is frequently referred to as a T7, which means that a resin T3 uptake (RT3u) has been done to correct for certain medications such as birth control pills, other hormones, seizure medication, cardiac drugs, or even ...

Reduces liveruptake of glucose Promotes gluconeogenesisin the liver Contributes to the maintenance and function of pancreatic islets Stimulates the immune system Increases deiodination of T4 to T3 Clinical significance The most common disease of growth hormone (GH) excess is a pituitary tumor composed of...
Positron emission tomography (PET) imaging is the clinical nuclear imaging technique with higher sensitivity and resolution. Although, single photon emission computed tomography (SPECT) is still the predominant technology worldwide, due to the easy availability ofγ-emitter radionuclides and the low cost...
There is no obvious relationship between the cellular permeability of various drugs (assessed via the percentage unchanged in the urine, given that the metabolism of drugs requires their cellular uptake, and a low value therefore reflects a high permeability) and the measured distribution coefficient ...
- The first RCTs of T3 as an augmenter of SSRIs are presented. Two large studies show different results and raise intriguing questions regarding the reasons for this discrep- ancy. - A PET imaging study suggests brain mechanisms for the an- tidepressant effect of L-T4 in bipolar ...
There is a need for valid and reliable measures of implementation-related constructs; however, practitioners are unlikely to use these measures if they are not pragmatic. Glasgow and Riley suggest that pragmatic measures are important to stakeholders, of low burden for respondents and staff, ‘action...
Molecular and cell biology assays showed CBFA2T3 to have characteristics consistent with a tumor suppressor [67] that lead to decreased glycolysis and stimulated mitochondrial respiration, and therefore may induce a Warburg–like effect [68] which is consistent with ketosis. This finding further releva...
