Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

Frozen blastocysts: Assessing the importance of day 5/day 6 blastocysts or blastocyst quality

Experimental and Therapeutic Medicine, 2022
The aim of the present study was to analyze the high-quality blastocyst (HB) rate in all embryo frozen cycles and investigate the pregnancy outcomes for day 5/day 6 (D5/D6) blastocysts with respect to the blastocyst quality in programmed single vitrified-warmed blastocyst transfer (SVBT).

Estrogen-dependent uterine secretion of osteopontin activates blastocyst adhesion competence. [PDF]

PLoS ONE, 2012
Embryo implantation is a highly orchestrated process that involves blastocyst-uterine interactions. This process is confined to a defined interval during gestation referred to as the "window of embryo implantation receptivity".

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]

, 2014
Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

Correlation of the position and status of the polar body from the fertilized oocyte to the euploid status of blastocysts

Frontiers in Genetics, 2022
Polar bodies are tiny cells that are extruded during oocyte meiosis and are generally considered not essential for embryonic development. Therefore, polar bodies have been widely used as important materials for the preimplantation genetic diagnosis of ...

Viability of in vitro produced embryos of gyr cattle (bos indicus) after cryopreservation by vitrifica-tion under field conditions

Boletim de Indústria Animal, 2016
The aim of this study was to evaluate the pregnancy rate of in vitro produced embryos of Gyr cattle (Bos indicus) after cryopreservation by the vitrification method under field conditions. Blastocysts in different developmental stages were transferred to

The Open Cryotop System Is Effective for the Simultaneous Vitrification of a Large Number of Porcine Embryos at Different Developmental Stages

Frontiers in Veterinary Science, 2022
The Superfine Open Pulled Straw (SOPS) system is the most commonly used method for vitrification of pig embryos. However, this system only allows the vitrification of four to seven embryos per straw.

Myeloid p38 activation maintains macrophage–liver crosstalk and BAT thermogenesis through IL‐12–FGF21 axis

Hepatology, EarlyView., 2022
Physiological activation of myeloid p38 controls macrophage IL‐12 production and crosstalk to the liver by modulating hepatic FGF21, and subsequently, brown adipose tissue thermogenesis during obesity Abstract Obesity features excessive fat accumulation in several body tissues and induces a state of chronic low‐grade inflammation that contributes to ...

EFFECT OF MORPHOLOGY AND BLASTOCYST DEVELOPMENT ON THE OUTCOME OF SINGLE-BLASTOCYST TRANSFER IN THE IN VITRO FERTILIZATION PROGRAMME

Zdravniški Vestnik, 2018
Background. Multiple pregnancy can be prevented by an elective single blastocyst transfer. The aim of this prospective study was to evaluate the effect of blastocyst development and morphology on the outcome of single blastocyst transfer. Methods.
