Chromosomal abnormalities in embryos

Molecular and Cellular Endocrinology, 2001
Chromosomal analysis was performed on 1620 embryos generated in vitro by patients with a poor prognosis of pregnancy. A diagnosis was yielded in 1596 embryos: 536 (34%) were euploid and 1060 (66%) carried chromosomal abnormalities. The results revealed a strong association between chromosomal abnormalities, cellular stage and percentage of ...

Chromosome abnormalities in meningiomas

Cancer Genetics and Cytogenetics, 1986
Cytogenetic analyses of eight meningiomas grown in culture for 1 week are reported. Normal karyotypes were found in three cases and hypodiploidy in the remaining five. In the five hypodiploid meningiomas, one chromosome #22 was missing in four cases, and one case exhibited a 22q- deletion.

Chromosome Abnormalities and Epilepsy

Epilepsia, 2001
Chromosome abnormalities are often associated with central nervous system (CNS) malformations and with other neurologic dysfunctions. In particular, patients with chromosomal abnormalities can have mental retardation (MR) and have a higher risk for seizures than that found in the general population (1).

Chromosome Abnormalities and Abortion

1974
Although spontaneous abortions represent one of the most frequent pathological entities, their causes have remained relatively obscure until the last decade. However, the work carried out at the Carnegie Institution at the beginning of the century and published in 1921 by Mall and Meyer had demonstrated the importance of abnormalities in the ...

Sex Chromosome Abnormalities

Nature, 1967
DURING the past decade several surveys have related the incidence of sex chromosome abnormalities among the general population with that among mentally deficient patients in hospital1–3. In 1963 Wegmann arid Smith4 carried out a buccal smear survey among a male population composed of juvenile delinquents and felons. They found the incidence of positive

Chromosome abnormalities in leiomyosarcomas

Cancer Genetics and Cytogenetics, 1988
Short-term cultures from seven soft tissue leiomyosarcomas were investigated cytogenetically. Sufficient mitoses for chromosome analysis were obtained in six cases, four of which had only normal karyotypes. In one tumor, an intramuscular leiomyosarcoma of the lower arm, a variety of nonclonal structural and numerical aberrations were found in two ...

Chromosomal abnormalities in sperm

Molecular and Cellular Endocrinology, 2001
The use of FISH (fluorescent in situ hybridization) in decondensed sperm nuclei has allowed, during the last decade, to indirectly study the chromosome constitution of human spermatozoa. Studies in control populations have been used to set up the basal level of aneuploidy for all human chromosomes and, based on conservative estimates, the percentage of

Chromosome Abnormalities in Myelofibrosis

Acta Haematologica, 2009
Cytogenetic analysis was performed on megakaryocyte-enriched cell fractions obtained by separation on discontinuous Percoll gradients from blood, bone marrow, and ascitic fluid of 12 patients with myelofibrosis with myeloid metaplasia (MMM). The most common abnormalities appeared to involve chromosomes 1, 3, 7, 8, 11, 13, 21 and 22.
