OP22.09: Does NIPS change the spectrum of detected major chromosomal aberrations (CHA)? Population-based data

The nature of chromosomal aberrations detected in humans exposed to benzene.

Benzene is an established cause of human leukemia that is thought to act by producing chromosomal aberrations and altered in cell differentiation. In several recent studies increased levels of chromosomal aberrations in peripheral blood lymphocytes were correlated with a heightened risk of cancer, especially hematological malignancies. Thus, chromosomal aberrations may be a predictor of future ...

Human Genetics – Chromosomal Aberrations

P-237: Elucidation The Role of Chromosomal Aberrations in Ovarian Reserve: A Retrospective Clinical Report

Background: Constitutional chromosome abnormalities are among the major contributors to the genetic causes of reproductive disorders. Despite all of worldwide efforts have been made so far, the prognosis for mosaic X chromosome aberration below 30% of unemployed has yet to be established. The purpose of this study was to assess the quantity and quiddity of chromosomal aberrations that may negat...

Relation of DNA ploidy to genetic aberrations detected by chromosomal CGH and FISH in gastric adenocarcinomas.

We analyzed DNA copy number aberrations (DCNAs) by chromosomal comparative genomic hybridization (CGH) in 93 consecutive sporadic gastric adenocarcinomas. In addition, numerical aberrations in chromosomes 7, 11, 17, and 18 were evaluated by fluorescence in situ hybridization (FISH). Gastric cancers were divided on the basis of nuclear DNA content measured by laser scanning cytometry (LSC) into ...

Propranolol induced chromosomal aberrations in Chinese hamster ovary cell line

Propranolol (PL), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. The present study was concerned with assessing the cytogenetic effects of this drug on Chinese hamster ovary (CHO) cell line. MTT assay was then carried out to determine the cytotoxicity index (IC50) of the drug. The IC50 value of PL was 0.43±0.02 mM. To investigate the clastogenic effect...
