Molecular characterization of embryos with different buoyancy levels in the yellowtail kingfish (seriola lalandi)
(MDPI, 2022)
The buoyancy of eggs and embryos is associated with successful development in pelagic fish. Buoyancy is the result of oocyte hydration, which depends on the osmotic force exerted by free amino acids (FAA) generated by yolk ...
Perceptions and beliefs about embryo cryopreservation in women and men who carry out assisted reproduction technology in Santiago, Chile Percepciones y creencias sobre criopreservación embrionaria en mujeres y hombres que se realizan técnicas de reproducc
(Sociedad Chilena de Obstetricia y Ginecologia, 2018)

Transvaginal ultrasound-guided cumulus oocyte complexes aspiration and in vitro embryo production in suckled beef and lactating dairy cattle on pasture-based management conditions
(2011)
This study was conducted to determine the use of repeated transvaginal ultrasound-guided cumulus oocyte complex (COC) aspiration on COC recovery rate, in vitro embryo production (IVP) and subsequent pregnancy rates in ...
Preimplantation embryotoxicity after mouse embryo exposition to reactive oxygen species
(INST HISTOL EMBRIOL-CONICET, 2007-04)
Exposure of either gametes or embryos to conditions and/or factors that generate oxidative
stress has been associated with impaired early embryogenesis. The effects of reactive oxygen species (ROS)
on mouse preimplantation ...
Fixation/Permeabilization: New Alternative Procedure for Immunofluorescence and mRNA In Situ Hybridization of Vertebrate and Invertebrate Embryos
(Wiley Periodicals, Inc., 2013)
A new procedure is described to visualize the spatial pattern of expression of proteins and mRNAs in
cryosections or whole-mounted leech, Drosophila, zebrafish, and chick embryos. Our principal contribution
is in the use ...
Potential biomarkers of DNA quality in cryopreserved fish sperm: impact on gene expression and embryonic development
(Wiley, 2020)
Sperm DNA quality and gene expression are crucial for early embryo development. Abnormal genomic processes can cause irreversible damage to totipotent cells, thereby altering the capacity for cell differentiation. ...
Morphometric evaluation of the embryo-uterine relationship of the pre and post implantational stages in rabbit (Oryctolagus cuniculus) Evaluación morfométrica de la relación embrio-uterina de las etapas pre y post implantacional en conejo (Oryctolagus cun
(Universidad de la Frontera, 2008)
The rabbit has demonstrated to be an outstanding implanting model. As an obligated ovulating animal, its pregnancy time can be established exactly. The morphologic observation of uterus cuts of 7, 8, 9 and 10 days post ...
Extra-embryonic tissue spreading directs early embryo morphogenesis in killifish
(Nature Publishing Group, 2017-06-05)
The spreading of mesenchymal-like cell layers is critical for embryo morphogenesis and tissue repair, yet we know little of this process in vivo. Here we take advantage of unique developmental features of the non-conventional ...
Mercury levels in eggs, embryos, and neonates of trachemys callirostris (testudines, emydidae).
(Universidad Nacional de Colombia, Facultad de Ciencias, Departamento de Biología, 2014-07-14)
We quantified total mercury concentrations in eggshells, egg yolks, and embryos from 16 nests of the Colombian Slider (Trachemys callirostris). Nests were collected in different stages of development, but estimated time ...
Scientific ethics of human origin Etica científica del origen humano
(1997)
The analysis of the early human life from the view point of a scientific ethics is presented. Life is a historical materioenergetic process of specific organization. This phylo-ontogenetic process is a continuos process ...
