Ultrastructural changes in preimplantation rabbit embryos.
Follicular oocytes and penetrated eggs of several mammalian species have been the subject of numerous electron microscope studies (rat: Sotelo 1959, Sotelo and Porter 1959, Franchi 1960, Odor and Renninger 1960, Szollosi and Ris 1961, Guinea pig: Anderson and Beams 1960, Adams and Hertwig 1964, Austin 1965. Barron and Franklin 1968. cat: Liss 1964. man: Stegner and Waternberg 1961, Zamboni et a...
متن کاملGray level cooccurrence histograms via learning vector quantization
In this paper, we propose to use learning vector quantization for the efficient partitioning of a cooccurrence space. A simple codebook is trained to map the multidimensional cooccurrence space into a 1-dimensional cooccurrence histogram. In the classification phase a nonparametric log-likelihood statistic is employed for comparing sample and prototype histograms. The advantages of vector quant...
متن کاملChanges in responsiveness of preimplantation mouse embryos to serum.
Changes in uptake of radioactive uridine and its incorporation into RNA were determined in preimplantation mouse embryos, from the 2-cell to the blastocyst stage, as a measure of their responsiveness to extracellular conditions. Two media were tested, one contained serum and the other contained bovine serum albumen as a control. An increase in the acid-soluble pool occurred at the 8-cell stage ...
متن کاملNovel Approach of Differential Staining to Detect Necrotic Cells in Preimplantation Embryos
Background This novel approach describes a rapid and simple method for identification of necrotic vs. viable cells within a mammalian blastocyst. MaterialsAndMethods Hatched bovine blastocysts produced in vitro were first incubated for 30 min in pre-equilibrated culture medium containing propidium iodide (PI; 300μg/ml) and bisbenzimide (Hoechst: H33342; 5μg/ml) fluorescent dyes. Embryos were th...
متن کاملSteroidogenesis in rabbit preimplantation embryos.
Rabbit preimplantation embryos were flushed from the reproductive tract at 24 hr (1- to 2-cell stage), 48 hr (morula), 72 hr (morula), 96 hr (blastocyst), 120 hr (blastocyst), and 144 hr (blastocyst) post coitum. At 168 hr (early postimplantation period), gestation sacs were excised, frozen, and sectioned in a cryostat. Delta5-3beta-Hydroxysteroid dehydrogenase [3(or 17)beta-hydroxysteroid:NAD(...
