SUMMARY Melatonin is known for its effects on both the sleep and reproductive system of mammals. The latter has melatonin receptors type 1 and 2, which act to regulate, among other things, cyclic AMP. Notwithstanding all the literature data, there is still no sound knowledge or a clear understanding of t...
A obtenção de oócitos de boa qualidade é essencial para o sucesso de diversas biotécnicas reprodutivas. Objetivou-se determinar o efeito de duas técnicas na recuperação de oócitos de boa qualidade em gatas e cadelas em diferentes estágios reprodutivos. Foram utilizados 43 pares de ovários de g...
Background: CPEB is considered as an RNA-binding protein first identified in Xenopus oocytes. Although CPEB1 was involved in the growth of oocyte, its role in goat follicular granulosa cell has not been fully elucidated. To clarify the functions of this gene in goat follicular granulosa cells, CPEB1-over...

Bovine herpesvirus 1 (BoHV-1) is an important bovine pathogen that is responsible for causing respiratory diseases and reproductive failures. The presence of BoHV-1 in an in vitro embryo production system affects fertilization, maturation, and embryonic development. The objective of this study was to eva...
ABSTRACT Objective. Evaluate mRNA expression of GDF9, BMP15, FGF2 and their main receptors, transforming growth factor beta receptor 1 (TGFβ-R1), bone morphogenetic protein receptor, type IB (BMPR-IB) and fibroblast growth factor receptor 2 (FGFR2) in bovine follicular cells. Materials and method...
SUMMARY: Vitrification is a physical process in which the concentrated cryoprotectant solution after exposure to extreme cold without ice crystal formation in living cells to be converted glassing state. In this study, maturation rate and ultrastructure of mouse oocytes followed by vitrification before o...
The aim of this study was to characterize the preantral ovarian follicular population in agoutis (D. leporina) by estimating the number of follicles at each developmental category, and also describe the morphometry and the specific features of the follicle and the oocyte by using light and transmission e...

Nos trópicos, o uso de raças adaptadas tem sido uma estratégia para minimizar o efeito do estresse térmico calórico (ETC). No entanto, faltam informações que quantifiquem o estresse e o seu efeito sobre a reprodução dessas raças. O objetivo deste estudo foi avaliar a qualidade do oócito recupe...
BACKGROUND: The domestic cat serves as an animal model for assisted reproductive studies of endangered felid species. To date, there are no data on the protein alterations following cryopreservation of oocytes in felid family. METHODS: Immature (germinal vesicle) domestic cat oocytes were vitrified in th...
BACKGROUND: Hydrogen sulfide has been shown to improve the quality of oocytes destined for in vitro fertilization. Although hydrogen sulfide is capable of modulating ion channel activity in somatic cells, the role of hydrogen sulfide in gametes and embryos remains unknown. Our observations confirmed the ...
