A novel method for transmission electron microscopy study of cytoplasmic fragments from preimplantation human embryos [PDF]

open access: yes, 2016
Transmission electron microscopy (TEM) is the main tool for exploring the intracellular damage and organelle distribution. The cause of producing embryo cytoplsamic fragmentation is not completely understood.

Maternal recognition of pregnancy in the horse : are MicroRNAs the secret messengers? [PDF]

open access: yes, 2020
The signal for maternal recognition of pregnancy (MRP) has still not been identified in the horse. High-throughput molecular biology at the embryo-maternal interface has substantially contributed to the knowledge on pathways affected during MRP, but an ...

Highly efficient RNA-guided base editing in rabbit

open access: yesNature Communications, 2018
Base editors can make targeted changes without inducing a double-stranded break. Here, the authors apply the BE3 and ABE7.10 systems to rabbit to create highly efficient targeted base substitutions and various mutation types, and show reduced frequency ...

Detrimental effects of lipopolysaccharides on maturation of bovine oocytes [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2019
Objective Gram-negative bacteria lipopolysaccharide (LPS) has been reported to be associated with uterine impairment, embryonic resorption, ovarian dysfunction, and follicle retardation.

Consent agreements for cryopreserved embryos : the case for choice [PDF]

open access: yes, 1998
Under current UK law, an embryo cannot be transferred to a woman’s uterus without the consent of both of its genetic parents, that is both of the people from whose gametes the embryo was created.

When it Pays to Rush: Interpreting Morphogen Gradients Prior to Steady-State

open access: yes, 2009
During development, morphogen gradients precisely determine the position of gene expression boundaries despite the inevitable presence of fluctuations. Recent experiments suggest that some morphogen gradients may be interpreted prior to reaching steady ...

THE IDENTIFICATION OF CHROMOSOMAL POLYMORPHISM IN ONE BREED OF IRAQI SHEEP

open access: yesThe Iraqi Journal of Veterinary Medicine, 1989
A chromosomal analysis of three breeds of Iraqi sheep (Karadi Arabi and Awassi) has been performed on peripheral lymphocytes. The modal chromosome number of all the three breeds was found to be (2n=54XX/54XY) for femal and male respectively.

YBX1 mediates alternative splicing and maternal mRNA decay during pre-implantation development

open access: yesCell & Bioscience, 2022
Background In mammals, maternal gene products decay and zygotic genome activation (ZGA) during maternal to zygotic transition (MZT) is critical for the early embryogenesis.

Terrestrial Planets Formation around Circumbinary Habitable Zone: Inward Migration in the Planetesimal Swarm [PDF]

open access: yes, 2012
According to the core accretion theory, circumbinary embryos can form only beyond a critical semimajor axis (CSMA). However, due to the relatively high density of solid materials in the inner disk, significant amount of small planetesimals must exist in the inner zone when embryos were forming outside this CSMA.
