Geographical distribution, nesting biotopes, and abundance of the yellow wagtail Motacilla citreola Pallas, 1776 (Passeriformes, Motacillidae), in the Middle Volga regionMoscow University Biological Sciences Bulletin - Tập 69 - Trang 130-137 - 2014
I. V. Murav’ev, E. A. Artem’eva, I. R. Beme
Analysis of literature data on the distribution and ecology of the yellow wagtail Motacilla citreola Pallas, 1776 (Passeriformes, Motacillidae, Motacillinae), was performed at the turn of the 19th and 20th centuries. Its current abundance has been estimated. Distribution patterns of the species at the studied territory within the European part of Russia, including the Middle Volga region, have bee...... hiện toàn bộ
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
Neutrophils Are Atypical Antigen-Presenting CellsMoscow University Biological Sciences Bulletin - Tập 78 - Trang 45-52 - 2023
N.V. Vorobjeva
Neutrophils are the most numerous blood leukocytes and are the “first line” of defense against pathogens in the focus of inflammation, where they perform effector functions of phagocytosis, degranulation, generation of reactive oxygen species, and the formation of neutrophil extracellular traps. It was believed for a long time that neutrophils are short-lived terminally differentiated phagocytes. ...... 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
New insight into the phylogeny of Mesozoa: Evidence from the 18S and 28S rRNA genesMoscow University Biological Sciences Bulletin - Tập 65 - Trang 167-169 - 2010
N. B. Petrov, V. V. Aleshin, A. N. Pegova, M. V. Ofitserov, G. S. Slyusarev
The phylogenetic relationships of two Mesozoa groups were studied by the comparative analysis of complete sequences of 18S and 28S rRNA. Two groups of Mesozoa were found to form a statistically supported clade in phylogenetic trees. The results of the analysis placed Mesozoa in the Spiralia group of Lophotrochozoa and showed the tendency of Mesozoa to converge with one of the Annelida groups.
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
