1. CCR3 antagonist impairs estradiol-induced eosinophil migration to the uterus in ovariectomized mice
Eosinophils are abundant in the reproductive tract, contributing to the remodeling and successful implantation of the embryo. However, the mechanisms by which eosinophils migrate into the uterus and their relationship to edema are still not entirely clear, since there are a variety of chemotactic factors that can cause migration of these cells. Therefore, to

2. DNA methylation, environmental exposures and early embryo development
Abstract The first crucial step in the developmental program occurs during pre-implantation, the time after the oocyte has been fertilized and before the embryo implants in the uterus. This period represents a vulnerable window as the epigenome undergoes dynamic changes in DNA methylation profiles. Alterations in the early embryonic reprogramming wave can im

3. Genes Regulating Maternal Recognition of Pregnancy in Domestic Animals: an Update
ABSTRACT Early embryonic mortality is one of the main sources of reproductive wastages and major constraints for full exploitation of the production potential of livestock. The survivality of embryo during early embryonic life is mostly dependent on the efficiency with which the maternal recognition of pregnancy (MRP) is established. Maternal recognition of

4. Effect of exercise on the maternal outcome in pregnancy of spontaneously hypertensive rats
PURPOSE:To evaluate the effect of exercise (swimming) on pregnancy in spontaneously hypertensive rats (SHR).METHODS: Thirty three pregnant female SHR were distributed into three groups (n=11 animals/group): SHR Control=non-exercised (sedentary); SHR Ex0 = exercised from day zero to day 20 of pregnancy; and SHR Ex7 = exercised from day 7 to 20 of pregnancy.

5. Compounds used to produce cloned animals are genotoxic and mutagenic in mammalian assays in vitro and in vivo
The compounds 6-dimethylaminopurine and cycloheximide promote the successful production of cloned mammals and have been used in the development of embryos produced by somatic cell nuclear transfer. This study investigated the effects of 6-dimethylaminopurine and cycloheximide in vitro, using the thiazolyl blue tetrazolium bromide colorimetric assay to assess

6. Reprogenetics: preimplantational genetics diagnosis
Preimplantational Genetics Diagnosis (PGD) is requested by geneticists and reproductive specialists. Usually geneticists ask for PGD because one or both members of the couple have an increased genetic risk for having an affected offspring. On the other hand, reproductive specialists ask for embryo aneuploidy screening (PGS) to assures an euploid embryo trans

7. Avaliação histomorfométrica do endométrio na fase lútea de mulheres férteis e inférteis / Evaluation the endometrial histomorphometry of fertile and infertile women during their luteal period
OBJETIVO: avaliar a histomorfometria do endométrio na fase lútea de mulheres férteis e inférteis. MÉTODOS: foram triadas 40 pacientes, 30 inférteis e 10 férteis, em seguimento na Clínica Ginecológica do HC-FMUSP, que concordaram em participar deste estudo. Foi realizada avaliação ultrassonográfica seriada a partir da menstruação, para determina

8. Avaliação da expressão gênica relacionada à receptividade endometrial em pacientes submetidos à embolização do mioma uterino / Evaluation of gene expression related to endometrial receptivity in patients undergoing uterine leiomyoma embolization
OBJETIVO: Avaliar a receptividade endometrial de pacientes submetidas à embolização do mioma uterino, analisando a expressão gênica de LIF, IL-11, IL-6, claudina-4, HoxA-10, HoxA-11, receptor de estrogênio e receptor de progesterona antes e após este procedimento. CASUÍSTICA E MÉTODOS: Foram colhidas biópsias aspirativas de endométrio de 30 pacien

9. Efetividade da UtilizaÃÃo de Incubadoras de CO2 Equipadas com filtro Hepa e Filtro Hepa-Voc para Cultivo de EmbriÃes em Ciclos de FertilizaÃÃo in Vitro / Effectiveness of Using CO2 Incubators equipped with HEPA filters and HEPA-You for Cultivation of Embryos in IVF Cycles
Introduction and objectives. The air quality in sterile environment is an important aspect to cell culture. It is known the culture conditions are essential for in vitro human embryo development; however there is no standardization for incubator filters in in vitro fertilization (IVF) laboratories. Recently, the incubator air quality has been receiving atten

10. Efeito do tratamento anti-inflamatÃrio na histologia endometrial, produÃÃo de prostaglandina e taxa de gestaÃÃo apÃs transferÃncia de embriÃes e/ou manipulaÃÃo cervical em Ãguas / Efeito do tratamento anti-inflamatÃrio na histologia endometrial, produÃÃo de prostaglandina e taxa de gestaÃÃo apÃs transferÃncia de embriÃes e/ou manipulaÃÃo cervical em Ãguas / Effect of anti inflammatory treatment in endometrial histology, prostaglandin production and pregnancy rates after embryo transfer and/or cervical manipulation in mares / Effect of anti inflammatory treatment in endometrial histology, prostaglandin production and pregnancy rates after embryo transfer and/or cervical manipulation in mares
Embryo transfer is currently the main breeding tool in equine reproduction. However it is still necessary to improve pregnancy to lower its costs.Among many factors that influence ET results, recipient mare management should be underlined. Currently the method utilized is non surgical transcervical transfer. Equine ET professionals observed that the less cer

11. Histological and BMP and Wnt gene expression evaluation in the bovine endometrium during embryo implantation / Avaliação histologica e da expressão genica de BMP e Wnt no endometrio durante a implantação embrionaria em bovinos
A implantação embrionária implica em alterações profundas do ambiente uterino, cujos eventos devem obedecer uma sincronia temporal e espacial com o estágio do desenvolvimento embrionário. Qualquer desequilíbrio nesta sincronia resulta em interrupção da gestação e o desconhecimento dos mecanismos que atuam nas interações materno-fetais inviabili

12. No evidence of association of MUC-1 genetic polymorphism with embryo implantation failure
Pregnancy loss can be caused by several factors involved in human reproduction. Although up to 50% of cases remain unexplained, it has been postulated that the major cause of failed pregnancy is an error of embryo implantation. Transmembrane mucin-1 (MUC-1) is a glycoprotein expressed on the endometrial cell surface which acts as a barrier to implantation. T
