Normal development of a zona-free oocyte to the blastocyst stage following ICSI

Normal development of a zona-free oocyte to the blastocyst stage following ICSI.

Monozygotic twins and transfer at the blastocyst stage after ICSI.

The incidence of monozygotic twinning (MZT) is higher in pregnancies conceived after assisted reproduction than after natural conception. Alterations, produced by ovarian stimulation, in-vitro culture conditions and specifically alterations of zona pellucida are mentioned as possible causes of this phenomenon. A retrospective review was performed of the incidence of MZT in pregnancies generated...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

Comparative stepwise pattern of reactive oxygen species production during in vitro development of fertilized and nuclear transferred goat embryos

Objective A unique feature of embryo metabolism is production of reactive oxygen species (ROS). It is well established that during in vitro culture, ROS levels increase over normal ranges observed for embryos developed in vivo. This study evaluates and compares the stepwise pattern of ROS production during in vitro development of reconstructed goat embryos produced by zona-free method of somati...

P-24: The Effect of Oocyte Activation with DTT on Development of Ovine Embryos in ICSI

Background: The objective of the current study was to determine the effect of activation of injected oocytes with dithiothreitol on development of ovine embryos derived from in vitro-matured oocytes and intracytoplasmic sperm.The injected oocytes with non-treated sperm were activated with 1) ionomycin (Io) + 6-dimethylaminopurine (6-DMAP) 2) DTT, 3) DTT+ ionomycin (I)+6-DMAP. Materials and Meth...
