[Radiation-induced changes in structural state of membranes of human blood cells].

To evaluate radiation-induced changes in the structural state of the membranes, blood samples of healthy donors were subjected to gamma radiation in the range of small (1-10 cGy) and medium doses (50 cGy-2 Gy). After irradiation, the microviscosity of lipid membranes of red and white blood cells was measured by ESR spin probe method. At doses exceeding 1 cGy, statistically significant changes of the degree of spontaneous erythrocyte hemolysis and of the lymphocyte plasma membrane microviscosity were observed.

[Association of polymorphic markers Arg72Pro of TP53 and T309g of MDM2 genes with non small cell lung cancer in Russians of Moscow region].

State Research Center "GosNIIgenetika", Moscow, 117545 Russia). Association of polymorphic markers Arg72Pro of TP53 gene and T309G of MDM2 gene with risk of non small cell lung cancer has been studied in Russians of Moscow region. We found an association of minor Pro/Pro genotype of polymorphic marker Arg72Pro (OR = 5.
