Cytogenetic examination of cosmonauts for space radiation exposure estimation

Are biological effects of space radiation really altered under the microgravity environment?

“…In fact, Table 4 Chromosome aberrations induced in the peripheral blood of astronauts. Pooled data for the group of astronauts included that prior to and after space flight (Snigiryova et al, 2012 (Table 4). Interestingly, the group of pre-flight astronauts (51 persons) showed a frequency of approximately twice that of the control dataset (114 persons), which consisted of people living in Moscow.…”

“…The attached panels A and B show vascular endothelial cells cultured in normal and the clinostat CO 2 incubators, respectively. The arrow → represents the actin stress fibre reconstruction.higher induction of chromosome aberrations were observed in the blood of astronauts that returned from space flight Snigiryova et al (2012). reported a summary of space radiation exposure estimation from the analysis of chromosome aberrations induced in the peripheral blood lymphocytes (PBLs) of astronauts…”
