1. Effect of hCG application at different moments of the estrous cycle on corpus luteum and uterine vascularization and serum progesterone concentration in mares
Abstract Establishment of pregnancy after embryo transfer is the ultimate goal of an embryo transfer program and increasing pregnancy rates and reducing pregnancy loss are mandatory. The utilization of treatments to improve conception rates in recipient mares has been the focus of several research groups over the last years and the results are controversial.

3. Pregnancy of Unknown Location: The Value of Frozen Section Analysis and Its Relation to Beta-hCG Levels and Endometrial Thickness
Abstract Objective Frozen section examination is a rapid method for identifying products of conception in endometrial curetting, yet its accuracy is inconclusive. The purposes of this study is to determine the accuracy of frozen section analysis of endometrial curetting in pregnancies of unknown location, and to verify the relation of β-human chorionic go

5. Induction of ovulation in quarter horse mares through the use of deslorelin acetate and human chorionic gonadotrophin (hCG)
The aim this study was to compare two protocols of induction for ovulation by desloreline acetate and hCG in Quarter Horse mares. The choice of the animals was based on the observations by the estrus, by rectal palpation of the ovaries and by ultrassonography of the follicular dynamics. After estrus detection and follicle control, the measurement of the foll

6. Purificação da gonadotrofina coriônica eqüina, do plasma sanguíneo de éguas prenhes, por cromatografia de afinidade / Equine chorionic gonadotrophin purification, from pregnant mare plasma, by affinity chromatography
A Gonadotrofina Coriônica Eqüina (eCG) é produzida pela égua prenhe e tem ação folículo estimulante e luteinizante em animais domésticos não eqüídeos. Um pool formado por plasma de 4 éguas prenhes, com média de 69 dias de gestação, foi purificado em coluna cromatográfica com resina de afinidade Blue Sepharose FF (BS). As frações que adsorve

7. Protocolos de sincronização da ovulação para inseminação artificial com tempo fixo em ovelhas / Protocol synchronization of estrus and ovulation in sheep
The aim of study was to test the hormonal protocol for FTAI (fixed timed artificial insemination) with progesterone for 6 days applying eCG (Equine Corionic Gonadotrophin) or BE (Estradiol Benzoate) and induction of estrus using: MAP (acetato de medroxiprogesterone) for 6, 9 and 14 days or a single dose of PGF2a or male effect. Experiment 1: In D0 each ewe (

8. Efeitos da bromocriptina na prevenção da síndrome do hiperestímulo ovariano precoce em mulheres de alto risco submetidas a fertilização in vitro / Effects of bromocriptine in the prevention of early ovarian hyperstimulation syndrome in high risk women submitted to in vitro fertilization
Objective: To evaluate the effect of bromocriptine for the prevention of either early moderate or severe ovarian hyperstimulation syndrome (OHSS) in high risk women submitted to in vitro fertilization. Patients and Methods: A double-blind, prospective, randomized study was carried out between February 2006 and November 2007 at the Human Reproduction Center,

9. Structural analysis of gubernaculum testis in cryptorchid patients submitted to treatment with human chorionic gonadotrophin
OBJECTIVES: To make a histological and stereological analysis of gubernaculum testis elastic system fibers, collagen and striated muscle cells in patients with cryptorchidism treated with human chorionic gonadotrophin (hCG). MATERIALS AND METHODS: Gubernacula tissue samples were obtained from 12 patients with cryptorchidism. Patients' ages ranged from 1 to 3

10. Expressão gênica diferencial de fibroblastos de linfonodos comprometidos ou não comprometidos de pacientes com câncer de mama após cultura isolada ou co-cultura com células epiteliais mamárias normais ou malignas / Differential gene expression of fibroblasts from involved or uninvolved lymph nodes from breast cancer patients cultured alone or cocultured with normal or malignant mammary epithelial cells
Tumor development may be influenced by epithelial-mesenchimal interactions in the primary site as well as in the involved lymph node from breast cancer patients. Our aim was to evaluate the proliferation rate and gene profile of fibroblasts obtained from involved and uninvolved lymph nodes from breast câncer patients and to determine the influence of normal

11. Adenomas hipofisarios : estudo clinico, morfologico e morfometrico; busca de fatores de prognostico utilizando o metodo imunoistoquimico / Pituitary adenomas : a clinical, morphological and morphometric study : searching for prognostic factors with the immunohistochemical method
Pituitary Adenomas (PA) are an easily identifiable and benign epithelial neoplasia. They are clinically detected through symptoms of an increased or decreased hormone rate and/or alterations of intra-cranial mass. They are classed in accordance with radiological / macroscopical aspects (macro versus microadenoma / invasive versus non-invasive), functional st
