1. Cryopreservation as a strategy for prevention of ovarian hyperstimulation syndrome in a public assisted reproduction service in São Paulo – Brazil
SUMMARY OBJECTIVE: This study aimed to evaluate the prevalence of ovarian hyperstimulation syndrome (OHSS) and associated risk factors in patients undergoing fertilization cycles at risk of OHSS (≥15 antral follicles or ≥15 oocytes aspirated) and submitted to cryopreservation of all embryos in the Human Reproduction Service of the Pérola Byington Hospi

2. Oocytes, embryos and pluripotent stem cells from a biomedical perspective
Abstract The veterinary and animal science professions are rapidly developing and their inherent and historical connection to agriculture is challenged by more biomedical and medical directions of research. While some consider this development as a risk of losing identity, it may also be seen as an opportunity for developing further and more sophisticated co

3. Assessing the association between hypoxia during craniofacial development and oral clefts
Abstract Objectives To evaluate the association between hypoxia during embryo development and oral clefts in an animal model, and to evaluate the association between polymorphisms in the HIF-1A gene with oral clefts in human families. Material and Methods The study with the animal model used zebrafish embryos at 8 hours post-fertilization submitted to 30%

4. Childhood cancer and environmental integrity: a commentary and a proposal
ABSTRACT Improvements in the health standards of developed and developing societies depend primarily on the relationships between economy and environment. Recent long-term changes in the chemical composition of man-made environments may be linked to changes in the biology of human beings. Here we argue that children are at the greatest risk of being affected

5. Transmission of Campylobacter coli in chicken embryos
Campylobacter coli is an important species involved in human cases of enteritis, and chickens are carriers of the pathogen mainly in developing country. The current study aimed to evaluate the transmission of C. coli and its pathogenic effects in chicken embryos. Breeder hens were inoculated intra-esophageally with C. coli isolated from chickens, and their e

6. Da antropologia pragmática à antropologia bioética: o princípio da prudência-ponte dirimindo o reducionismo em bioética pertinente à vida humana no nível molecular
This thesis aims to demonstrate that there is a reductionism in bioethics and this comes out as one of three ways: a) topological; b) proximity; and c) life secularization. These three forms of reductionism hinder a definition of a moral status and also a prudential deal of the genetic materials and human embryos. Thus, there is a quickly advance of biotechn

7. Epidemiologia e caracterização molecular do vírus da Influenza em quatro espécies de pinguins na Região Antártica. / Epidemiology and molecular characterization of the influenza virus in four penguin species of the antartic region.
Epidemics and pandemics of influenza usually refer to infections in human beings. The influenza virus is not, however, restricted to humans and can cause infirmity and death in other species including horses, swine, marine mammals, birds, and others. Ecological studies of viral infections have led to the hypothesis that the influenza viruses that attack mamm

8. Investigação microbiológica e análise qualitativa de achados bacteriológicos e micológicos em placas de cultivo de embriões em laboratório de reprodução humana / Microbiological investigation and analysis of qualitative findings bacteriological and mycological culture plates from embryos in the laboratory of human reproduction
Introdução: Em laboratórios de Reprodução Humana, o controle de qualidade é de fundamental importância para o sucesso dos procedimentos. A realização correta dos procedimentos influem diretamente nos resultados, principalmente porque a vagina, o líquido folicular e o sêmen não podem ser esterilizados. Um alto grau de higiene, limpeza e o descarte

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

A review the decision of the Supreme Court ruled as a constitutional law 11.105/05 (Biosafety Law) concerning the possibility of using embryonic stem cells for scientific research derived from the manipulation of frozen embryos more than three years or impractical for human reproduction. The decision became historic because it can generate the 1st public hea

11. Living human oocytes with first polar body extrusion from patients with moderate and severe endometriosis contain a higher percentage of telophase I oocytes. / Análise não invasiva do fuso celular de oócitos e os resultados dos procedimentos de reprodução assistida em mulheres inférteis com endometriose
Introduction: Although it has been a controversial issue for decades, a deleterious role of endometriosis on assisted reproductive techniques (ART) outcomes is questioned, which may be related to oocyte quality. For a mature oocyte be prepared for fertilization is necessary that the meiotic spindle keeps its integrity and its function. Objectives: To compare

12. Molecular cloning and expression analysis of a zebrafish novel zinc finger protein gene rnf141
ZNF230 is a novel zinc finger gene cloned by our laboratory. In order to understand the potential functions of this gene in vertebrate development, we cloned the zebrafish orthologue of human ZNF230, named rnf141. The cDNA fragment of rnf141 was obtained by rapid amplification of cDNA ends (RACE). The open reading frame (ORF) encodes a polypeptide of 222 ami
