Outcome of preimplantation genetic diagnosis of translocations.
OBJECTIVE To review 35 cases of preimplantation genetic diagnosis (PGD) of translocations with several methods, including telomeric probes. DESIGN Retrospective study. SETTING Clinical IVF laboratory. PATIENT(S) Thirty-five couples with one partner carrying a chromosomal translocation. INTERVENTION(S) PGD of translocation after polar-body or embryo biopsy. MAIN OUTCOME MEASURE(S) Preg...
متن کاملPreimplantation Genetic Diagnosis for Aneuploidy and Translocations Using Array Comparative Genomic Hybridization
At least 50% of human embryos are abnormal, and that increases to 80% in women 40 years or older. These abnormalities result in low implantation rates in embryos transferred during in vitro fertilization procedures, from 30% in women <35 years to 6% in women 40 years or older. Thus selecting normal embryos for transfer should improve pregnancy results. The genetic analysis of embryos is called ...
متن کاملMeiotic segregation of Robertsonian translocations ascertained in cleavage-stage embryos--implications for preimplantation genetic diagnosis.
BACKGROUND The aim of this study was to ascertain the prevalence of meiotic segregation products in embryos from carriers of 13/14 and 14/21 Robertsonian translocations and to estimate the predictive value of testing single cells using the fluorescence in situ hybridization (FISH) technique, to provide more information for decision-making about PGD. METHODS In this prospective cohort study, t...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولChromosomal microarray versus karyotyping for prenatal diagnosis.
BACKGROUND Chromosomal microarray analysis has emerged as a primary diagnostic tool for the evaluation of developmental delay and structural malformations in children. We aimed to evaluate the accuracy, efficacy, and incremental yield of chromosomal microarray analysis as compared with karyotyping for routine prenatal diagnosis. METHODS Samples from women undergoing prenatal diagnosis at 29 c...
