Chromosome abnormalities in meningiomas
Cancer Genetics and Cytogenetics, 1986Cytogenetic 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.

The influence of parity and gravidity on first trimester markers of chromosomal abnormality
Prenatal Diagnosis, 2000 We have studied changes in first trimester fetal nuchal translucency (NT) and maternal serum free β-hCG and PAPP-A with gravidity and parity in 3252 singleton pregnancies unaffected by chromosomal abnormality or major pregnancy complications.

Chromosomal abnormalities in sperm
Molecular and Cellular Endocrinology, 2001The 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, 2009Cytogenetic 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.

Chromosome Abnormalities and Abortion
1974Although 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 ...

Chromosomal Abnormalities in Cancer
New England Journal of Medicine, 2008This review gives an account of chromosomal aberrations in cancer cells. Such abnormalities have typically been associated with hematologic cancers, but recent work has shown a variety of chromosomal changes in solid tumors, including prostate cancer and non–small-cell lung cancer.

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, 1988Short-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 ...

Screening for chromosomal abnormality
Seminars in Ultrasound, CT and MRI, 1998Screening for fetal abnormalities has become one of the most high profile health care issues of modern times. This issue is predicated on major advances in health care technology that permit wider detection of fetal anomalies, including the development of more advanced biochemical markers and improvements in ultrasound imaging.

Chromosome abnormalities in CML
Baillière's Clinical Haematology, 1987The Ph chromosome is the hallmark of CML, where it is found in more than 90% of the cases. Cytogenetically, it usually results from a t(9;22)(q34;q11). The Ph arises in a stem cell and in chronic phase is found in all haematopoietic cell lineages, although it causes only increased granulopoiesis, and sometimes increased thrombopoiesis; furthermore ...
