Sentence examples for tsh secretion from inspiring English sources

TSH secretion is controlled by thyrotropin-releasing hormone (TRH) which is secreted from the hypothalamus.

Second, our finding of reciprocal changes in TSH and free T4 with common genetic variation in PDE8B provides further support for the suggestion, arising from the data of Arnoud-Lopez et al. (10) that PDE8B plays a role in TSH signaling in the thyroid gland rather than operating at the level of central control of TSH secretion.

In the ME, TRH is released into portal blood vessels and stimulates thyroid-stimulating hormone (TSH) secretion from the pituitary.

Until now it is unknown how exactly the pulsatile release of TSH is regulated, although there is evidence that the pulsatile TSH secretion pattern is mediated by TRH51.

Our results indicate that neurologically complete cervical spinal injury results in the complete loss of pineal melatonin production and that neither the loss of melatonin nor the loss of spinal afferent information disrupts the rhythmicity of cortisol or TSH secretion.

Other factors that should be taken into consideration include, physiological and biochemical differences between humans and other species, thyroid hormone-independent effects of anti-thyroid drugs, circadian rhythms in TSH secretion, sex differences, physical and psychological stress.

This escape phenomenon is associated with the down-regulation of the sodium iodide (NaI) symporter (NIS) thereby reducing the amount of inorganic iodine in the thyroid so that thyroxine (T4) and thyroid-stimulating hormone (TSH) secretions are returned to normal physiological levels (Eng et al. 1999).

The increased hypothalamus TRH secretion could not only lead to hyperplasia and hypertrophy of pituitary TSH-secreting cells and increased secretion of TSH but also stimulate PRL-secreting cells, promote PRL synthesis and secretion.

If the results show that TSH level declined partially, but the thyroid function made no significant improvement, long-term increased secretion of anterior pituitary TSH-secreting cells should be considered [ 2]; and this may lead to the formation of adenoma on the basis of TSH-secreting cell hyperplasia.

Based on these data, the decrease in total serum T3 and T4 levels in the trifluralin treated rats was due to enhanced peripheral metabolism and an increase in bile flow that results in a compensatory increase in TSH synthesis and secretion.

Data obtained in our study shows that in lung cancer patients cortisol, TRH, TSH and GH secretion is altered with loss of circadian rhythmicity.
