1. ADAMTS proteoglycanases downregulation with impaired oocyte quality in PCOS
ABSTRACT Objective: A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4) and ADAMTS-5 normal expression levels are essential for ovulation and subsequent fertilization. The objective of the present study was to assess expression pattern of these genes in cumulus cells (CCs) taken from patients with polycystic ovary syndrome (PCOS) and

2. Intravascular histiocytosis: case report of a rare disease probably associated with silicone breast implant,
Abstract Intravascular histiocytosis is a rare condition characterized by the aggregate of histiocytes within dilated dermal vessels. The diagnosis is mainly histophatological and immunohistochemical. We describe a case of a 55 year-old female patient presenting erythematous/purple patches on the breasts, back and limbs. She previously presented ductal carci

3. Immunohistochemical assessment of symptomatic postmenopausal endometrial polyps in tamoxifen users and nonusers: a case control study
ABSTRACT BACKGROUND: Endometrial polyps are common in postmenopausal women, and the effect of tamoxifen use (a risk factor for endometrial polyps) on their pathogenesis is unclear. OBJECTIVES: To evaluate the expression of hormone receptors and markers for proliferation/apoptosis (Ki-67 and Bcl-2) in endometrial polyps in postmenopausal users and nonuser

4. Immunohistochemical localization of progesterone receptors alpha (PRA) in ovary of the pseudopregnant rabbit
Abstract Progesterone plays an important role in the reproductive function and follicular development in mammals. The aim of the present study was to examine the localization of progesterone receptor alpha (PRA) in ovary of pseudopregnant rabbit by immunohistochemical methods. Samples were collected from 14 h. to 18 days of pseudopregnancy. At the first stag

5. Melatonin effects on ovarian follicular cells: a systematic review
RESUMO A melatonina é conhecida por seus efeitos no sono e no sistema reprodutivo dos mamíferos. Este último tem receptores de melatonina tipos 1 e 2, que atuam para regular, entre outras coisas, o AMP cíclico. Apesar de todos os dados da literatura, ainda não há um conhecimento sólido ou uma compreensão clara da ação do hormônio na fisiologia das

6. Expression of estrogen and progesterone receptors in astrocytomas: a literature review
Gliomas are the most common type of primary central nervous system neoplasm. Astrocytomas are the most prevalent type of glioma and these tumors may be influenced by sex steroid hormones. A literature review for the presence of estrogen and progesterone receptors in astrocytomas was conducted in the PubMed database using the following MeSH terms: “estrogen

7. Angioma serpiginosum: report of an unusual acral case and review of the literature
AbstractWe report the case of a 35-year-old woman with deep-red asymptomatic macules on the plantar and dorsal skin of the right great toe. Histopathologic fi ndings were compatible with Angioma serpiginosum. Immunohistochemical stains for estrogens and progesterone receptors were negative. Dermoscopy showed an erythematous parallel ridge pattern with double

8. Receptores de estrógeno e progesterona, Ki67, Bcl-2 E Cox-2 em pólipos endometriais de mulheres na pré e pós-menopausa e associação com a obesidade, = : Estrogen and progesterone receptors, Ki67, Bcl-2 and Cox-2 markers in benign endometrial polyps in pre and postmenopausal women and their association with obesity / Estrogen and progesterone receptors, Ki67, Bcl-2 and Cox-2 markers in benign endometrial polyps in pre and postmenopausal women and their association with obesity
Introdução: A prevalência de obesidade tem aumentado em todo o mundo e hoje já representa um problema de saúde pública. Na população feminina, seu aumento ocorre principalmente nos anos próximos da transição para menopausa. O aumento de peso representa um risco para diversas comorbidades, dentre elas um importante fator de risco para patologia end

9. Estrogen and progesterone receptors in endometrial polyps of women exposed and not exposed to tamoxifen and in atrophic endometrium / Receptores de estrógeno e progesterona em pólipos endometriais de usuárias e não usuárias de tamoxifeno e no endométrio atrófico
Introduction: Tamoxifen has been used for the treatment of strogen receptor-positive breast cancer. The effect of tamoxifen in breast cancer is the it inhibition cancer cell growth by competitive antagonism with strogen for strogen receptor (ER). The mechanism of action of tamoxifen in this receptor varies among different tissues, with antagonist effect (e.g

10. Expressão de receptores de estrógeno e progesterona Ki-67, Bcl-2 e ciclo-oxigenase-2 em pólipos endometriais de mulheres na pós-menopausa / Expression of estrogen and progesterone receptors, Ki-67, Bcl-2 cyclooxigenase - 2 in endometrial polyps of postmenopausal women
Introdução: Os pólipos endometriais são achados frequentes em mulheres na pós-menopausa e têm sido raramente associados a lesões precursoras e neoplasia endometrial. O desconhecimento de sua patogênese e potencial de malignidade tem levado a polipectomia de rotina o que pode estar expondo muitas mulheres a um risco cirúrgico desnecessário. Objetivo

11. Estrous cycle and stress: influence of progesterone on the female brain
The female brain operates in a constantly changing chemical milieu caused by cyclical changes in gonadal hormones during the estrous cycle (menstrual cycle in women). Such hormones are highly lipophilic and pass readily from the plasma to the brain where they can influence neuronal function. It is becoming clear that the rapid reduction in peripheral circula
