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 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 کاملChromosome aberration analysis in persons exposed to low-level radiation from the JCO criticality accident in Tokai-mura.
Chromosome aberrations were studied in peripheral blood lymphocytes of 43 persons who were exposed to low-level radiation of mixed neutrons and gamma-rays resulting from the JCO criticality accident. When the age-adjusted frequencies of dicentric and ring chromosomes were compared with the dose calibration curve established in vitro for 60Co gamma-rays as a reference radiation, a significant co...
متن کاملComparison of chromosome aberration frequencies in pre- and post-flight astronaut lymphocytes irradiated in vitro with gamma rays.
If radiosensitivity is altered in a microgravity environment, it will affect the accuracy of assessing astronauts' risk from exposure to space radiation. To investigate the effects of space flight on radiosensitivity, we exposed a crewmember's blood to gamma rays at doses ranging from 0 to 3 Gy and analyzed chromosome aberrations in mitotic lymphocytes. The blood samples were collected 10 days ...
متن کاملChromatic aberration at PHELIX
The influence of the dispersion of glass seams only relevant for femtosecond lasers with a pulse length below 100 fs. This commonly used approximation holds only for visible and IR light. For UV fs-laser Z. Bor stated out that due to the large dispersion in the UV regime fs-pulses with a duration of a few hundred femtoseconds are significantly affected in lenses by the group delay [1]. When a p...
