What next for preimplantation genetic screening (PGS)? Experience with blastocyst biopsy and testing for aneuploidy.
Blastocysts more commonly have a normal karyotype than cleavage-stage embryos do. Moreover, blastocysts have also made a metabolic transition from catabolism and recycling of the oocyte's reserves and resources, processes that fuel the first 3 days of cleavage. Although not all blastocysts are karyotypically equal, it is still to be determined to what extent a mosaic karyotype might be a normal...
متن کاملApplying lessons learned from TDDB testing
Since 1979 various papers and have been published on modeling the gate dielectric using Time Dependent Dielectric Breakdown (TDDB) testing. There are primarily 2 models used, the linear E field model and the 1/E field model. These are based on different failure kinetics and both predict vastly different lifetimes for the dielectric. As a result the majority of I.C. manufacturers used the 1/E mo...

متن کاملPreimplantation Genetic Testing
Preimplantation genetic testing (PGT) involves analysis of biopsied cells as part of an assisted reproductive procedure. It is generally considered to be divided into 2 categories. Preimplantation genetic diagnosis (PGD) is used to detect a specific inherited disorder and aims to prevent the birth of affected children in couples at high risk of transmitting a disorder. Preimplantation genetic s...
متن کاملWhat next for preimplantation genetic screening? Beyond aneuploidy.
Many published papers suggest a favourable impact of preimplantation genetic screening (PGS) on implantation and pregnancy rates, but more recent randomized studies have not confirmed, or could not conclude, that PGS actually improved implantation rates. Team inexperience in embryo screening has been mentioned as the origin of the discrepancies; thus some clinicians allege a need for more power...
