Study of Cellulose-Destroying Activity of Actinobacteria Associated with AntsMoscow University Biological Sciences Bulletin - Tập 76 - Trang 20-27 - 2021
Yu. V. Zakalyukina, A. R. Zaytsev, M. V. Biryukov
Among actinobacteria associated with ants Camponotus vagus, Formica cunicularia, and Lasius niger, their nests, and intact soils, cellulolytic activity was screened in medium with carboxymethyl cellulose (CMC) using Congo Red dye. Assessment of culture fluids of tested strains on the CMC-plates and comparing them with solutions of the commercial cellulase preparation allowed for quantifying their ...... hiện toàn bộ
Effect of the peptide Semaks on UV-induced damaging of the plasma membranes of peritoneal macrophages in miceMoscow University Biological Sciences Bulletin - Tập 62 - Trang 97-99 - 2007
S. K. Pirutin, V. B. Turovetsky, A. V. Odgaieva, A. A. Kamensky
We studied the effect of nootropic peptide Semaks and its inactive analog on the efficiency of UV-induced damaging of the peritoneal macrophage plasma membrane. The increase of the time after the UV-irradiation (with doses 5 and 6 J/cm2) from 15 to 60 min led to a substantial increase in the number of damaged cells. The UV-irradiation effect has been subjected to a substantial decrease with the ad...... hiện toàn bộ
Role of Secondary Oxidative Stress in the Bactericidal Action of AntibioticsMoscow University Biological Sciences Bulletin - Tập 75 - Trang 218-223 - 2021
A. V. Akhova, A. G. Tkachenko
Exposure to β-lactam, fluoroquinolone, and aminoglycoside antibiotics caused an increase in the production of hydrogen peroxide and the expression of OxyR-regulon of the oxidative stress response in Escherichia coli cells. Under the conditions of microaeration, the attenuation of secondary oxidative stress due to the addition of the antioxidant thiourea influenced the antibacterial effect of fluor...... hiện toàn bộ
Regulation of the Actin Cytoskeleton Transformation in the Cell by ARP2/3 Complex. ReviewMoscow University Biological Sciences Bulletin - - 2017
A. S. Chemeris, A. V. Vakhrusheva, N. I. Derkacheva, O. S. Sokolova
The cytoskeleton is formed by a network of protein filaments, including microtubules, actin filaments and intermediate filaments. Filaments permeate the entire cytoplasm; they are involved in maintaining the cell shape, they organize and anchor the organelles, they control the transport of various molecules, cell division and provide signal transduction. To implement these diverse and complex func...... hiện toàn bộ
Comparative analysis of space-time organization of biological systems in periodic and dialyzed cultures of Synechococcus sp. PCC 6301Moscow University Biological Sciences Bulletin - Tập 65 - Trang 107-111 - 2010
E. L. Barsky, A. F. Lebedeva, Ya. V. Savanina, S. Yu. Koroleva, Yu. N. Korolev, E. S. Lobakova
Data on biopolymers, their distribution, and spatial order in whole cells and in a certain cell layer of the cyanobacterium Synechococcus sp. PCC 6301 culture grown under periodic and dialysis conditions were obtained by the method of internal reflection spectroscopy. The fundamental distinction between the types of culture behavior under these cultivation conditions was shown. A similar approach ...... hiện toàn bộ
