Association between blastocyst morphology and outcome of single-blastocyst transfer [PDF]

Reproductive BioMedicine Online, 2013
The aim of this study was to assess the ability of three individual blastocyst morphology parameters - expansion and hatching (EH) stage, inner cell mass (ICM) grade and trophectoderm grade - to predict outcome of a cycle with single-blastocyst transfer. The study was a secondary analysis of data prospectively collected in a large multicentre trial.

Adhesive and degradative properties of human placental cytotrophoblast cells in vitro. [PDF]

, 1989
Human fetal development depends on the embryo rapidly gaining access to the maternal circulation. The trophoblast cells that form the fetal portion of the human placenta have solved this problem by transiently exhibiting certain tumor-like properties ...

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery

IJU Case Reports, EarlyView.
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...

Partial Trajectory: The Story of the Altered Nuclear Transfer-Oocyte Assisted Reprogramming (ANT-OAR) Proposal [PDF]

, 2007
This essay aims to tell the story of the “altered nuclear transfer-oocyte assisted reprogramming,” or ANT-OAR, proposal—from its conception by Professor William Hurlbut of the President’s Council on Bioethics—to its adoption and promotion by a group of ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Antioxidative Potential of Red Deer Embryos Depends on Reproductive Stage of Hind as a Oocyte Donor

Animals, 2020
The aim was to compare the blastocyst stages of red deer embryos in respect of in vitro fertilization (IVF) efficiency, morphology, apoptotic and proliferative abilities, and antioxidative potential according to the reproductive status of hinds.

Bta-miR-10b secreted by bovine embryos negatively impacts preimplantation embryo quality [PDF]

, 2019
In a previous study, we found miR-10b to be more abundant in a conditioned culture medium of degenerate embryos compared to that of blastocysts. Here, we show that miR-10b mimics added to the culture medium can be taken up by embryos. This uptake results

GNPAT/USP30 Stabilizes DRP1 Protein to Promote Mitochondrial Fission and Functional Damage in COPD Progression

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Our previous study revealed the role of glycerol phosphate O‐acyltransferase (GNPAT) in regulating chronic obstructive pulmonary disease (COPD). However, its further mechanisms remained unclear. In this study, COPD models were established by exposing mice to cigarette smoke particulates.

POSSIBLILTIES FOR A SINGLE EMBRYO TRANSFER IN AN IN VITRO FERTILIZATION PROGRAMME

Zdravniški Vestnik, 2003
Background. Since in in vitro fertilization two embryos – blastocysts are routinely transferred, the twin pregnancy rates are higher than in the general population.

Histological cut of a paraffin-embedded blastocyst: Optimized protocol for murine blastocysts

MethodsX, 2020
Paraffin-embedded tissues have been used for research and therapeutic applications for decades, as they represent a valuable tool in histology and for molecular analysis, as well as being a way to preserve tissue samples for long periods at a low cost.
