1. Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)
Abstract Distress can be defined as a biological response of an individual to long-term threats to its homeostasis and it should be avoided from an animal welfare perspective. High levels of stress hormones and the expression of abnormal behaviours are responses normally observed in distressed animals. Captive environments can provoke distress, especially wh

2. TSH-receptor antibodies may prevent bone loss in pre- and postmenopausal women with Graves' disease and Graves' orbitopathy
ABSTRACT Objective Thyrotoxicosis is established risk factor for osteoporosis due to increased bone turnover. Glucocorticoids often administered for Graves' orbitopathy (GO) have additional negative effect on bone mineral density (BMD). Our aim was to examine the influence of thyroid hormones, TSH, TSH-receptor antibodies (TRAb) and glucocorticoid treatment

3. Estresse precoce e alterações do eixo hipotálamo-pituitária-adrenal (HPA) na depressão. / Early Life Stress and alterations of the Hypothalamic-Pituitary-Adrenal (HPA) axis in depression.
Introduction: Several studies suggest that stress in early stages of development can induce persistent changes in the ability of the Hypothalamic-Pituitary-Adrenal (HPA) axis to respond to stress in adulthood. The imbalance of cortisol has been identified as a biological correlate of depressive disorders. These abnormalities seem to be related to changes in

5. Influência da adrenalectomia bilateral nos eventos neurodegenerativos no modelo do parkinsonismo experimental pela 6-OHDA nigral. Enfoque aos mecanismos parácrinos gliais envolvidos na neuroproteção e cicatrização / Text not informed by the author
This study has the objective to evaluate the effect of the bilateral adrenalectomy in the neurodegenerative process and cicatrization on the nigroestriatal pathway injury through 6-hydroxydopamine (6-OHDA) in rat, and in this way contribute for the interpretation of the adreno esteroides hormones effects in the neurodegenerative and neurotrophics process in

6. Non-invasive endocrine monitoring using fecal steroid analysis: opportunities and challenges
During the past two decades, techniques for the non-invasive analysis of fecal steroid metabolites (estrogen, androgen, progestagen and glucocorticoid metabolites) have been developed. These techniques have been used for research with mammals, birds, reptiles, and to a lesser extent in fish; species studied included domestic and laboratory animals, as well a

7. Functional Link Between Glucocorticoid Hormones and the TP53 Tumor Suppressor Gene in a Rat Glioma Cell Model / Interação funcional entre hormônios glicocorticóides e o gene supressor de tumor TP53 em um modelo celular de glioma de rato
Tanto hormônios glicocorticóides (GCs) como o gene supressor de tumor TP53, medeiam a resposta celular a uma diversidade de condições fisiológicas de estresse, sendo reguladores fundamentais do processo de vida/morte de diversos tipos celulares. A interação funcional entre estes fatores vem sendo explorada, recentemente, revelando que GCs exercem um e

8. Caracterização funcional de genes diferencialmente regulados por glicocorticóides e análise do proteoma em linhagem de glioma sensível à hormônios anti-tumorais glicocorticóides / Functional characterization of glucocorticoid differentially regulated genes and proteomic analysis of the anti-tumoral effect of glucocorticoid in a glucocorticoid-sensitive rat glioma cell line
The glucocorticoid (GC) growth suppression response is controlled through cellular cascades in which the transcription of primary response genes regulates the expression and activity of a diverse set of genes including important factors for cell cycle progression. However, the functional connection between the GC-regulated transcriptional events and cell cyc

9. Prolactin induces adrenal hypertrophy
Although adrenocorticotropic hormone is generally considered to play a major role in the regulation of adrenal glucocorticoid secretion, several reports have suggested that other pituitary hormones (e.g., prolactin) also play a significant role in the regulation of adrenal function. The aim of the present study was to measure the adrenocortical cell area and

10. Effect of medroxyprogesterone acetate on thyrotropin secretion in adult and old female rats
Steroid hormones have been implicated in the modulation of TSH secretion; however, there are few and controversial data regarding the effect of progesterone (Pg) on TSH secretion. Medroxyprogesterone acetate (MPA) is a synthetic alpha-hydroxyprogesterone analog that has been extensively employed in therapeutics for its Pg-like actions, but that also has some

11. Regulação da expressão do promotor do gene do receptor de glicocorticoide em clones de celulas transfectadas com o photo-oncogene c-jun
Glucocorticoid receptors ( GR ) mediate the cellular response to glucocorticoid hormones which are known for their anti-inflammatory and anti-tumoral actions. The mechanisms involved on the regulation of GR gene expression are extremely important for the cellular response to the hormone and remain unknow. Using transient transfections, we have previously rep

12. Transcription initiation of transfected mouse mammary tumor virus LTR DNA is regulated by glucocorticoid hormones.
A chimeric gene, recombined in vitro, containing a long terminal repeat (LTR) sequence from the proviral DNA of mouse mammary tumor virus and the thymidine kinase (tk) gene of Herpes Simplex Virus was introduced into L tk- cells. No transcription of LTR RNA was observed in transfected cells when glucocorticoid hormones were absent from the growth medium. Acc
