Tumores hipofisários secretores de TSH: relato de dois casos e revisão da literatura
(Sociedade Brasileira de Endocrinologia e Metabologia, 2009)
INTRODUÇÃO: Tumores hipofisários secretores de hormônio estimulante da tireoide (TSH), tireotropinomas, são raros e correspondem a menos de 2% de todos os adenomas da hipófise. Manifestam-se clinicamente com sintomas e ...
T3 rapidly modulates TSH beta mRNA stability and translational rate in the pituitary of hypothyroid rats
(ELSEVIER IRELAND LTD, 2011)
Whereas it is well known that T3 inhibits TSH beta gene transcription, its effects on TSH beta mRNA stability and translation have been poorly investigated. This study examined these possibilities, by evaluating the TSH ...
Desarrollo de sistemas de diagnóstico para la hormona estimulante de tiroides (TSH) en suero humano: ELISA e Inmuno-PCR cuantitativa (qIPCR)
(2018-03-09)
La función de la glándula tiroides está regulada por la hormona estimulante de la tiroides (TSH). Dado que el control por retroalimentación de la secreción de TSH es exquisitamente sensible a las hormonas tiroideas ...
Experimental evidence that endogenous TSH modulates microsomal antigen expression: clinical implications Evidencia experimental que el TSH endogeno modula la expresion del antigeno microsomal: implicancia clinica.
(1993)
The purpose of this work was to study if TSH has a role in TPO antigen expression in vivo. Using the cytotoxicity assay we measured TPO expression and correlated it with TSH serum levels in 3 groups of rats: control, ...
Estudio de la secreción de TSH en el hipertiroidismo subclínico.

Introducción: El hipertiroidismo subclínico se presenta con una concentración normal de
hormonas tiroideas periféricas, TSH (hormona estimulante del tiroides sérico) suprimido

Novel immunoassay for TSH measurement in rats
(Sbem-Soc Brasil Endocrinologia & Metabologia, 2017)
Measuring thyroid hormones is an important aspect for the study of metabolism and for monitoring diseases in both human and animal models. The traditional method for hormone measurement in rats is the radioimmunoassay ...
Abnormal circadian rhythm and increased non-pulsatile secretion of thyrotrophin in Sheehan's syndrome
(Blackwell Science Ltd, 1999-10-01)
OBJECTIVE It has previously been shown that patients with postpartum pituitary necrosis (Sheehan's syndrome, SS) have paradoxically increased TSH levels and loss of the nocturnal TSH surge. This study sought to determine ...
Determinación del límite superior de referencia de TSH, en una población de individuos en la ciudad de México
(2011-10-27)
Context: The establishment of the reference intervals of thyrotropin (TSH) has changed during the last decades. This point performs vital importance, due to the fact that the TSH has a great sensibility, reflecting accurately ...
TSH and TPOAB as predictors of thyroid disease in diabetic patients
(Lippincott Williams & Wilkins, 2008-03-01)
We tested the values of antithyroid peroxidase antibody and thyrotropin levels for the development of thyroid dysfunction in 109 diabetic patients. Baseline thyrotropin level was a predictor of thyroid dysfunction in ...
