Prompt cytomolecular identification of chromosome aberration in irradiated blood cells
Background: understanding the genomic alteration induced by ionizing radiation still remains to be a methodological challenge in genetic field. The energy released from this type of radiation can potentially causes structural and numerical alterations in lymphocytes, which in turn converts them into abnormal tumor cells. Chromosomal abnormalities associated with specific type of hematological m...
متن کاملGeneralized concept of the LET-RBE relationship of radiation-induced chromosome aberration and cell death.
The frequency of chromosome aberrations per traversal of a nucleus by a charged particle at the low dose limit increases proportionally to the square of the linear energy transfer (LET), peaks at about 100 keV/micron and then decreases with further increase of LET. This has long been interpreted as an excessive energy deposition over the necessary energy required to produce a biologically effec...
متن کاملModels of chromosome aberration induction: an example based on radiation track structure.
A few examples of models of chromosome aberration induction are summarised and discussed on the basis of the three main theories of aberration formation, that is "breakage-and-reunion", "exchange" and "one-hit". A model and code developed at the Universities of Milan and Pavia is then presented in detail. The model provides dose-response curves for different aberration types (dicentrics, transl...
متن کاملRare chromosome structural aberration characterizing oncology malignancy.
UNLABELLED Ring chromosome aberration are rare abnormality potentially involving any chromosome in patients diagnosing in Oncology. The present review and case study has focused on the ring chromosome associated with oncology malignancies. MATERIAL AND METHODS An electronic peer review article search was performed systematically to obtain relevant literature with the CINAHL, Google scholar, a...
متن کاملLymphocyte chromosomal aberration assay in radiation biodosimetry
Exposure to ionizing radiations, whether medical, occupational or accidental, leads to deleterious biological consequences like mortality or carcinogenesis. It is considered that no dose of ionizing radiation exposure is safe. However, once the accurate absorbed dose is estimated, one can be given appropriate medical care and the severe consequences can be minimized. Though several accurate phy...
