A single i.p. injection of vincristine (1000 microgram/kg) into rats increased the plasma concentration of corticosterone after a latent period of 4 hr; the effect lasted for 48 hr. The response was dose related with the threshold dose being 100 microgram/kg and the maximal effect occurring after 250 microgram/kg. Vincristine also increased plasma corticosterone levels in hypophysectomized rats...
Epigenetic modification is one of the effective factors in tumorigenesis. Epigenetic processes, especially aberrant DNA methylation, play important role in thyroid cancer, and many tumor suppressor genes including PTEN, RASSF1A and TIMP3 are aberrantly methylated and silenced in thyroid cancer. Because of the specified pattern of DNA methylation in various tumor cells, it is suggested that thes...
Background & Objective: Turner syndrome is a chromosomal abnormality which encompasses multiple disorders. High prevalence of thyroid diseases has been described in patients with TS but the extent of this association is controversial. The purpose of this study was to determine the prevalence of thyroid disorders in patients with TS in the endocrine center of Iran university of medical scien...
A thyroid disease is a medical condition impairing the function of the thyroid. The thyroid hormones act on nearly every cell in the body. Imbalance in production of thyroid hormones arises from dysfunction of the thyroid gland itself, the pituitary gland, which produces thyroid-stimulating hormone (TSH), or the hypothalamus, which regulates the pituitary gland via thyrotropin-releasing hormone...
INTRODUCTION Measuring thyroid stimulating hormone levels alone may be insufficient to appropriately evaluate thyroid function. Reduced thyroid stimulating hormone levels associated to normal/reduced FT4 levels should prompt investigation of pituitary function, on suspicion of hypopituitarism. Pituitary macroadenomas are the most common cause of hypopituitarism; among these, macroprolactinomas ...
