1. Ectopic Cushing syndrome in Colombia
ABSTRACT Objective The aim was to describe the clinical features of patients with ectopic Cushing syndrome (ECS) from Colombia and compare these findings with other series to provide the best management for these patients. Materials and methods Records of patients with ECS from 1986 to 2017 were retrospectively reviewed; patients with a diagnosis of adre

2. Clinical and subclinical maternal hypothyroidism and their effects on neurodevelopment, behavior and cognition
ABSTRACT Clinical and subclinical hypothyroidism are the most common hormonal dysfunctions during pregnancy. Insufficient maternal thyroid hormones (THs) in the early stages of pregnancy can lead to severe impairments in the development of the central nervous system because THs are critical to central nervous system development. In the fetus and after birth,

3. Alterações sistêmicas e comportamentais de interesse odontológico em pacientes com síndrome de Down / Dental implications of systemic and behavior alterations in Downs syndrome patients
Downs syndrome (DS) is the most common genetic disorder and it is caused by the trissomy of 21 chromosome. It is characterized by mental retardation, physical alterations and several systemic co morbidities. The aim of this study was to evaluate behavior and systemic alterations with dental implications in DS patients and discuss the dental management of the

4. Avaliação Comportamental e dos Níveis Séricos e Metabolismo Periférico dos Hormônios Tireoidianos em Ratos Submetidos ao Estresse Social Seriado. 2010. / Behavioral Evaluation, of Serum Levels and Peripheral Metabolism of Thyroid Hormones in Rats Subjected to Social Stress series. 2010
O estresse tem um impacto profundo sobre o desenvolvimento de diversas psicopatologias, afetando vários processos fisiológicos, como o sistema endócrino, imunitário e nervoso central. A exposição a eventos estressantes é capaz de perturbar a regulação normal dos eixos neuroendócrinos, e embora a maioria dos estudos neste campo apontem, principalmen

5. Avaliação da toxicidade da Ipomoea carnea em caprinos durante o período perinatal: estudos de neuroteratologia / Evaluation of the toxicity of Ipomoea carnea in goats during postnatal period
Ipomoea carnea, a shrub plant, is a toxic plant largely distributed throughout Brazil and others topical countries. This plant possess swainsonine, an indolizidinic alkaloid as the most important active toxic principle, which promotes cellular accumulation of not metabolized oligossacarides, due to inhibition of acid or lisossomal αmanosidasis enzyme,

6. Oligomerização, estruturas à baixa resolução, ligação ao DNA e ao ligante dos receptores de hormônios tireoidianos / Thyroid hormone receptor oligomerization, low resolution structures, DNA and ligand binding
The thyroid receptors (TRs) are proteins, which are involved in diverse and important physiological functions in the organisms, since they are regulators of development, cell divison and differentiation, metabolism and homeostasis. They are responsible by the regulation of specific gene transcription, through pleiotropic effects of lipophilic hormones in the

7. Estudo do desempenho sistolico e diastolico do miocardio ventricular esquerdo em adultos obesos, pelo Doppler pulsado tecidual / Study of the systolic and diastolic behavior of the left myocardial ventricle in obese individuals by means of pulse - wave tissue Doppler
The aim of this study is to analyze the left ventricular (LV) myocardial behavior in obese individuais, with or without hypertension, associating it (or not) with hypertrophy by means of pulse-wave tissue Doppler (pTD). The seven constitutive groups of this study were formed by 20 subjects each, including men and women whose age ranged between 30 and 50 year

8. Thyroid hormone and estrogen interact to regulate behavior.
Environmental perturbations that increase plasma thyroid hormone (T3) concentrations also profoundly affect female reproductive behavior and physiology. We explored whether these effects were mediated by interactions between T3 receptor (TR) and estrogen receptor (ER). This hypothesis was of interest because the half-site of a consensus T3 response element D

9. Induction of a proinflammatory program in normal human thyrocytes by the RET/PTC1 oncogene
Rearrangements of the RET receptor tyrosine kinase gene generating RET/PTC oncogenes are specific to papillary thyroid carcinoma (PTC), the most frequent thyroid tumor. Here, we show that the RET/PTC1 oncogene, when exogenously expressed in primary normal human thyrocytes, induces the expression of a large set of genes involved in inflammation and tumor inva

10. Thyroid abnormalities and hepatocellular carcinoma in mice transgenic for v-erbA.
The v-erbA oncogene consists of an avian retroviral gag gene fused to a mutated thyroid hormone receptor. To define better its role as an oncogene in mammals and its ability to function as a dominant negative transcription factor, transgenic mice expressing v-erbA ubiquitously were generated. The effects of v-erbA are pleiotropic, tissue-specific and dose de

11. Reproduction-related behaviors of Swiss–Webster female mice living in a cold environment
Based on a molecular neuroendocrine theory about cold environments, thyroid hormone levels, and liganded thyroid hormone receptor interference with estrogen receptor function, experiments were designed to test female mouse reproductive behaviors in the cold. Because natural seasonal temperature declines would usually be associated with decreased photope

12. Crystal Structure of Iodotyrosine Deiodinase, a Novel Flavoprotein Responsible for Iodide Salvage in Thyroid Glands*
The flavoprotein iodotyrosine deiodinase (IYD) salvages iodide from mono- and diiodotyrosine formed during the biosynthesis of the thyroid hormone thyroxine. Expression of a soluble domain of this membrane-bound enzyme provided sufficient material for crystallization and characterization by x-ray diffraction. The structures of IYD and two co-crystals contain
