In Xenopus embryos at stage 32/33 one eye anlage was removed and the other made into a compound double-nasal or double-temporal eye. At metamorphosis the optic nerve was cut and the compound eye was permitted to regenerate fibres both to its own contralateral tectum and to the ipsilateral 'virgin' tectum. One month later the projection from the compound eye to the virgin tectum was assessed aut...

This article contributes to such comprehension: principles turn in its analytical interpretation provided by Rorty applied an indicator revealing commonality difference Frege’s Husserl’s positions regarding key issues concepts.

background: the mitochondria are an important source of adenosine triphosphate (atp) production in pre-implantation embryo. therefore, the objective of this study was to investigate the effect of vitrification and in vitro culture of mouse embryos on their mitochondrial distribution and atp content. methods: the embryos at 2-pn, 4-cell and blastocyst stages were collected from the oviduct of st...
We employed embryos of the zebrafish, Danio rerio, for our studies on the in vivo bystander effect between embryos irradiated with high-dose X-rays and naive unirradiated embryos. The effects on the naive whole embryos were studied through quantification of apoptotic signals at 25 h post fertilization (hpf) through the terminal dUTP transferase-mediated nick end-labeling (TUNEL) assay followed ...
