Cellular differentiation induces various morphological changes, including elongation, in mitochondria. Preimplantation embryos have round-shaped mitochondria, characteristic of undifferentiated cells. However, there is controversy regarding the precise mitochondrial morphology blastocyst embryos, which are generated from two cell lineages : inner mass (ICM) and differentiated trophectoderm (TE)...

Several key developmental events are associated with early embryonic pregnancy losses in beef and dairy cows. These problems observed at a greater frequency pregnancies generated from in-vitro-produced bovine embryos. This review describes critical that arise during oocyte maturation, fertilization, development, compaction blastulation, cell lineage specification, elongation, gastrulation, plac...

A natural gas droplet is generated at certain thermodynamic conditions through three stages: supersaturation, where the has more molecules than it should have in equilibrium, forming “embryos” of liquid phase; nucleation, embryos form groups different shapes and sizes nanometer order; growth, number increases until equilibrium reached. In this paper, homogeneous nucleation growth applied to gra...

Dechorionaed embryos of the zebrafish, Danio rerio, at 1.5 h post-fertilization (hpf) were irradiated with alpha particles from an 241Am source. Thin polyallyldiglycol carbonate (PADC) films with a thickness of 16 mm were used as support substrates for holding the embryos and recorded alpha-particle hit positions, and thus enabled calculation of the dose absorbed by the embryos. The irradiated ...

in the present study, the toxic effects on the embryos and larvae of the turbot were used as a model to investigate the diazinon, which contaminates aquatic ecosystems. the number of dead embryos significantly increased in response to diazinon concentrations 0.2, 0.4, 0.8, 1.6, 3.2, and 7.4 mg/l. the 48h lc50 value of diazinon for turbot embryos was estimated at 1.85 mg/l. dose–response decrea...
