Preimplantation diagnosis / Ke-hui Cui
Summary: Aims to develop reliable procedures for determining the genetic status of embryos derived by IVF procedures prior to implantation. Prenatal diagnosis allows pregnancy to be established using only acceptable embryos

Telomerase Activity in Human Preimplantation Embryos
<p>Telomerase, a ribonucleoprotein, has been described as an essential component of highly proliferative cells, which stabilizes the telomeres and avoids cellular senescence. Telomerase has been identified in various embryonic cell stages, hematopoietic cells, and in >85% of tumor tissue biopsies …

The effects of propylparaben on preimplantation embryo development
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-11 without embargo terms

Micrurgy and in Vitro Preimplantation Development of Rabbit Embryos
Made available in DSpace on 2014-12-14T15:29:41Z (GMT). No. of bitstreams: 1 7820989.pdf: 3167012 bytes, checksum: cab7a5f928b1087fdaf1d78e04bf8b3d (MD5) Previous issue date: 1978

The Impact Of Mitochondria On Preimplantation Development In The Rhesus Macaque
… cellular and molecular properties of oocytes and preimplantation embryos. A key component of all cells, including oocytes and embryos, is the mitochondrion, which produces energy and maintains its own DNA for encoding proteins necessary for energy production. Defects in either the proteins …

Role Of Maternal Sin3a In Reprogramming Gene Expression During Mouse Preimplantation Development
… that maternal SIN3A is essential for preimplantation development and the reprogramming of genes expression, because inhibiting the maturation-associated increase in SIN3A leads to an arrest in mouse embryonic development and unfaithful reprogramming of gene expression in 2-cell mouse …

A Study of Guideline for Genetic Counselling in Preimplantation Genetic Diagnosis (PGD)
Preimplantation genetic diagnosis (PGD), also known as embryo screening, is a technique used to identify genetic defects in embryos created through in vitro fertilization before pregnancy. PGD is considered another way to prenatal diagnosis. PGD refers specifically to when one or both genetic …

Bioinformatics Investigation on the Role of Obox Gene Family in Preimplantation Embryo Development
<p>Preimplantation embryo development (PED) refers to the period from fertilization to implantation in mammals. This complex process is critical for successful implantation and pregnancy. Although studies on PED have been conducted, using mainly the mouse as a model organism, the gene regulatory …

Leukemia Inhibitory Factor (LIF): Murine Preimplantation Embryo Development, Implantation Rates, and Skeletal Development
<p>Leukemia inhibitory factor (LIF) is a pleiotropic cytokine which demonstrates perplexing physiological effects. It has been demonstrated that LIF is essential for implantation in mice. Little is known relating to the manner by which LIF effects pre-implantation and post-implantation development. …

Modulation of bovine preimplantation embryonic development and pregnancy by FGF2, LIF, and IGF1
… of this work was to understand FLI modulation of preimplantation embryo development and pregnancy outcomes in cattle. This work aimed to: 1) characterize an embryo phenotype following FLI supplementation to the bovine in vitro embryo production system; 2) investigate the effects of FLI on embryo …

Involvement of mitochondrial transcription factor A (TFAM) in porcine gametogenesis and preimplantation embryo development
… and distribution of TFAM in the gametes and preimplantation embryos of a domestic pig (Sus scrofa), a livestock species of major economic significance. We hypothesized that TFAM will be expressed at high levels in oocytes and embryos and that sperm mitochondria should be devoid of TFAM since …

Effect of a maternal inflammatory challenge during the preimplantation period on offspring development and phenotype
The preimplantation mammalian embryo is sensitive to its immediate surroundings: alterations to its in vitro or in vivo environment can affect not only the immediate events of blastocyst formation, but can also give rise to long-term phenotypic consequences during fetal and/or postnatal life. For …

Effects of prepartum plane of nutrition during mid- or late gestation on beef cow BW, BCS, blood hormone concentrations, and preimplantation embryo
… cow BW, BCS, blood hormone concentrations, and preimplantation embryos. In Exp. 1, multiparous Angus and Angus x Simmental cows (n = 33; BW = 664 ± 78 kg) were fed diets formulated to provide 3 planes of nutrition: 100% NRC energy and protein requirement (REQ), 70% NRC requirement (70%REQ) or …
