Chromosomal Abnormalities in Reimplantation Development
Direct testing of the outcome of human female meiosis demonstrated that up over a half of oocytes from IVF patients of advanced reproductive age are aneuploid, originating comparably from meiosis I and meiosis II errors, with potential probability of aneuploidy rescue in an almost half of oocytes with sequential first and second meiotic errors. One fifth of abnormalities originating from meiosi...
متن کاملChromosomal abnormalities in bovine embryos and their influence on development.
A study was undertaken to determine the relationship between chromosome composition and embryo development. Bovine cumulus-oocyte complexes were matured in vitro and exposed to semen from one of three different bulls, one of which was a 1/29 Robertsonian translocation carrier. There were no significant differences among the three bulls in their sperm penetration or in the cleavage or developmen...
متن کاملChromosomal abnormalities and embryo development in recurrent miscarriage couples.
BACKGROUND Chromosomal abnormalities are an important cause of spontaneous abortion and recurrent miscarriage (RM). Therefore, we have analysed the incidence of chromosomal abnormalities and embryo development in patients with RM. METHODS Preimplantation genetic diagnosis (PGD) was performed on 71 couples with RM and 28 couples undergoing PGD for sex-linked diseases (control group). Chromosom...
متن کاملChromosomal abnormalities in a pineocytoma.
Tumors of the pineal region represent about 0.4-1% of intracranial neoplasms, including those tumors of germ cell origin (primarily germinomas and teratomas, which represent about 80% of pineal malignancies), and those tumors of the pineal parenchyma (pineocytoma and pineoblastoma). Pineocytoma is composed of relatively mature cells of the pineal parenchyma, whereas pineoblastoma represents a m...
متن کاملChromosomal abnormalities in Hodgkin's disease.
Numerous neoplastic states have associated or causal cytogenetic abnormalities. In some cancers, specific chromosomal abnormalities appear to correlate with the clinical characteristics and prognosis. Cytogenetic analysis of Hodgkin's disease is thought to be technically difficult and only a small number of cases with evaluable results have been reported. We have attempted cytogenetic studies o...
