  • It is one of the nutrients most often found to be deficient in the Western diet, and there is evidence that deficiency is a problem on a worldwide scale. (encyclopedia.com)
  • This heterogeneity appears to constitute the underlying cause for the focal cell hyperplasia and eventually the formation of thyroid and adrenal nodules, under the influence of growth stimulatory factors. (mdpi.com)
  • Among the main stimulatory factors are the pituitary tropic hormones, thyroid-stimulating hormone (TSH) or thyrotropin and adrenocorticotropic hormone (ACTH), which regulate the growth and function of their respective target cells, and the insulin/insulin-like growth factor system, that, through its mitogenic effects, can stimulate the proliferation of these cells. (mdpi.com)
  • The predominance of one or the other of these growth stimulatory factors appears to determine the natural history of thyroid and adrenal nodular disease. (mdpi.com)
  • The incidence of malignancy in MNG is 4-14%, and risk factors are family history of thyroid carcinoma, history of neck radiation, prior surgery, and presence of cervical lymphadenopathies. (intechopen.com)

  • Factor XI or plasma thromboplastin antecedent is the zymogen form of factor XIa, one of the enzymes of the coagulation cascade. (wikipedia.org)
  • Various products of these genes are enzymes involved in the activation or degradation of carcinogens/pro-carcinogens. (bvsalud.org)
  • Hyposomatotropism is a deficiency in the release of pituitary growth hormone (somatotropin), resulting in short stature. (medscape.com)
  • The bone minerals calcium, phosphate and magnesium are all maintained at higher concentrations in utero to achieve adequate bone accretion. (frontiersin.org)
  • Once the baby is born, loss of placental delivery of minerals causes a sudden drop in serum concentrations of these bone minerals which triggers a rise in regulating factors such as PTH, 1,25-dihydroxyvitamin D [1,25(OH) 2 D, calcitriol] and FGF23 to maintain postnatal homeostasis. (frontiersin.org)
