The north-eastern region of India is reported to be the center of origin and rich in diversity of Citrus (L.) species, where some wild and endangered species namely Citrus indica, Citrus macroptera, Citrus latipes, Citrus ichagensis and Citrus assamensis exist in their natural and undisturbed habitat. In order to have comprehensive information about the extent of genetic variability and the occ...

Previous studies in humans and animal models provided evidence that the Fhit gene is an early target for cigarette smoke. We compared the induction of a variety of molecular and cytogenetical alterations in B6-129(F(1)) mice, either wild type or Fhit(+/-), after whole-body exposure to environmental cigarette smoke (ECS) for 15 consecutive days. Both mouse genotypes responded to ECS with a loss ...

BACKGROUND Recently, the importance of cytogenetics has grown in the diagnosis, prognosis and treatment of leukemias and myelodysplastic syndromes. 5-azacytidine is a drug that has well-known cytogenetical effects and is approved in the treatment of myelodysplastic syndromes. To date, no studies have been performed to evaluate the impact of 5-azacytidine on the chromosomes of patients with hema...

a cytogenetical study on 13 alfalfa (medicago sativa) cultivars available in iranian forest and rangelands genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. such cytogenetic information is useful for planning hybridization programs. cluster analysis of meiotic data and ordination of cultivars...

In the present study, we investigated the influence of cytological stains in analyzing DNA extracted from cytological slides by comparative genomic hybridization (CGH). Multiple imprint cytological slides were prepared for fresh-frozen breast cancer tissue samples and the slides were stained by three staining methods for each sample. Under microscopic observation, cancer cells were selectively ...
