    Abstract: Extracellular DNA-containing substances can be used as a marker of the balance between two processes: elimination of cells with critical number of lesions and repair of genetic material due to the work of adaptive systems. The idea of using this criterion was inspired by the results of measuring exDNA in blood plasma of chronically irradiated indiv... Show More

    Abstract: Exposure to ionizing radiation leads to exhaustion of the pool of stem cells, increases differentiated cell stress, and activated reparation and apoptosis processes. Apart from well-documented acute effects, radiotherapy leads to delayed effects manifesting in few years after successful treatment. The aim of our study was the development of a test ... Show More

    Abstract: Reactions to gamma-irradiation in an acute dose of 750 R in C57BL/6, 101/Hf and С3H/Sn mice at different physiological levels were analyzed. In C3H/Sn and 101/Hf mice, light scattering spectrum was shifted towards small particles, while in C57BL/6 mice increased contribution of large particles was observed. In 3 weeks, a shift towards larger partic... Show More

    Abstract: Microgravity simulation in rats resulted to changes in eye lavage content. Molecular subfraction analysis with laser correlation spectroscopy revealed significant differences in the pattern of particle distribution in five intervals: 1.9 -2.56 nm, 4.64-6.25 nm, 91.3 nm, 165-300 nm, and 400-734 nm. Microgravity modeling induced a series of interrel... Show More

    Abstract: The effect of a 100-300-fold attenuated geomagnetic field on the embryonic development of great ramshorn Planorbarius corneus and oxidation-reduction properties in water environment were studied in a hypomagnetic chamber. Mainly the hypomagnetic field effected beneficial influence on the development of mollusks: teratogenic effects were less massiv... Show More

    Abstract: Interferon-γ (IFN-γ) is a pleiotropic cytokine with antiproliferative and immunomodulatory activities that are crucial for the regulation of immune responses. We examined a group of military pilots. The examinees were divided into 3 subgroups: ground personnel (9 persons, control group), 17 pilots with <1000 h flight time, and 12 pilots with >1000 h flight time. No differences in IFN-α se...

    Abstract: Changes in cardiovascular system (CVS) under conditions of hypogravity simulated using 7- and 21-day ortho- and antiorthostatic hypokinesia at different angles were studied. The aim of the experiment was selection of informative CVS parameters most sensitive to these conditions. Simultaneous recording of 26 CVS parameters on a spiroartheriocardiory... Show More
