UNLABELLED Many cancers display both structural (s-CIN) and numerical (w-CIN) chromosomal instabilities. Defective chromosome segregation during mitosis has been shown to cause DNA damage that induces structural rearrangements of chromosomes (s-CIN). In contrast, whether DNA damage can disrupt mitotic processes to generate whole chromosomal instability (w-CIN) is unknown. Here, we show that act...

This study was conducted to evaluate the level of chromosomal damage in perinatal asphyxia and correlate it with severity of asphyxia. Fourty term neonates with asphyxia and twenty term babies without asphyxia were included in this case control study. Blood samples were collected within 24 hours of birth for karyotyping and oxidative stress by serum malondealdehyde (MDA) estimation. The degree ...

Chromosomal damage and apoptosis were analyzed in users of mouthwash and/or alcoholic beverages, using the micronucleus test on exfoliated oral mucosa cells. Samples from four groups of 20 individuals each were analyzed: three exposed groups (EG1, EG2 and EG3) and a control group (CG). EG1 comprised mouthwash users; EG2 comprised drinkers, and EG3 users of both mouthwashes and alcoholic beverag...
