1. Cushing disease due to a somatic USP8 mutation in a patient with evolving pituitary hormone deficiencies due to a germline GH1 splicing variant
SUMMARY We present the unique case of an adult Brazilian woman with severe short stature due to growth hormone deficiency with a heterozygous G to T substitution in the donor splice site of intron 3 of the growth hormone 1 (GH1) gene (c.291+1G>T). In this autosomal dominant form of growth hormone deficiency (type II), exon 3 skipping results in expression of

2. Management of hypopituitarism: a perspective from the Brazilian Society of Endocrinology and Metabolism
ABSTRACT Hypopituitarism is a disorder characterized by insufficient secretion of one or more pituitary hormones. New etiologies of hypopituitarism have been recently described, including head trauma, cerebral hemorrhage, and drug-induced hypophysitis. The investigation of patients with these new disorders, in addition to advances in diagnosis and treatment

3. Primary hypothyroidism with exuberant dermatological manifestations,
Abstract Thyroid hormone has effects on the skin. Patients with hypothyroidism have changes such as dry, scaly and rough skin. Increase carotene in the dermis becomes a yellowish tone to the skin of the patient with hypothyroidism. There is an increase in capillary cycle (anagen phase) and nail growth and a reduction in eccrine gland secretion. It is a case

4. Effect of Photoperiod on the Egg Production, Plasma Luteinizing Hormone, Follicle-Stimulating Hormone, Gonadal Hormones, and Mrna Levels of Lh and Fsh in the Hypothalamic-Pituitary-Gonadal Axis of Pigeons
ABSTRACT We investigated the egg production, changes in luteinizing hormone (LH), follicle-stimulating hormone (FSH), gonadal hormones, and their mRNA levels in the hypothalamic-pituitary-gonadal axis of White King pigeons submitted to different photoperiods. The treatments consisted of three photoperiods (8 h light (L):16 h dark (D), 12L:12D, and 16L:8D), w

5. Stress, strain, and pregnancy outcome in postpartum cows
Abstract Stress affects the productivity and fertility of cattle. Stress causes strain and individual animals experience different amounts of strain in response to the same amount of stress. The amount of strain determines the impact of stress on fertility. Typical stresses experienced by cattle include environmental, disease, production, nutritional, and ps

6. Effect of metformin on semen quality
ABSTRACT Various studies have linked metformin, a universally antidiabetic drug, with semen quality; however, such a direct link has not been established. This review systematically addresses and summarizes the effect of metformin on semen quality, particularly sperm function. We searched the MEDLINE electronic database for English articles and abstracts con

7. Effects of the phytoestrogen genistein on the development of the reproductive system of Sprague Dawley rats
OBJECTIVES: Genistein is known to influence reproductive system development through its binding affinity for estrogen receptors. The present study aimed to further explore the effect of Genistein on the development of the reproductive system of experimental rats. METHODS: Eighteen post-weaning female Sprague Dawley rats were divided into the following groups

8. 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

9. Desenvolvimento estrutural da hipófise e ontogenia das células adeno-hipofisárias do dourado Salminus brasiliensis (Cuvier, 1816) Teleostei, Characiformes. / Structural development of the pituitary gland and ontogeny of adenohypophyseal cells from dourado Salminus brasiliensis (Cuvier, 1816) Teleostei, Characiformes.
Neste estudo foi verificado que a hipófise de S. brasiliensis era composta por dois tecidos, a neuro hipófise (NH) e a adeno-hipófise (AH). Nesta última, foram distinguidos sete tipos celulares. Na RPD foram detectadas as células adrenocorticotrópicas e prolactínicas, na PPD as células gonadotrópicas, somatotrópicas e tireotrópicas, e na PI, as c�

10. Paradoxical sleep deprivation is related to muscle atrophy and damages muscle recovery / A privação de sono paradoxal em ratos está associada a atrofia muscular e déficit na recuperação muscular
Introduction: Paradoxical sleep deprivation (PSD) in rats is able to induce reductions in body mass and body fat, due to increased secretion of pituitary-adrenal axis hormones. Considering that PSD is also associated with a decrease in anabolic hormones, skeletal muscle can also be strongly influenced, causing atrophy damaging its recovery after a lesion. Ob

11. Serum levels of hypothalamic-pituitary-testicular axis hormones in men with or without prostate cancer or atypical small acinar proliferation
INTRODUCTION: Substantial controversy exists regarding the association between testosterone serum levels and prostate cancer. OBJECTIVE: To evaluate the levels of hypothalamic-pituitary-testicular axis hormones in the sera of men with prostate cancer and atypical small acinar proliferation as well as those with normal biopsies. METHODS: A study cohort of 186

12. The hypothalamic-pituitary-adrenal axis in anxiety and panic
This review article focuses on the differential activation of the hypothalamic-pituitary-adrenal (HPA) axis in generalized anxiety and panic. The results of experimental studies that assayed adrenocorticotropic hormone, cortisol and prolactin show that real-life panic attacks as well as those induced by selective panicogenic agents, such as lactate and carbo
