Direct and chemosignal-mediated effects of immune activation on behavior, glucocorticoid level, and body temperature in male mice during social conflict
Pleiades Publishing Ltd - Tập 37 - Trang 179-185 - 2010
I. E. Kolosova, D. V. Petrovski, M. P. Moshkin
Behavioral and physiological effects mediated by activation of immune system response to the injection with sheep red blood cells (SRBC) have been established to be mediated by chemosignal modification to a considerable extent while conducting experiments on BALB/cLac and C57Bl/6j male mice. Control mice of both strains have been characterized by the same increase of plasma coricosterone concentra...... hiện toàn bộ
Morphometric Variability of the Upper Molars and Mitochondrial Phylogeography of the Edible Dormouse Glis glis L. (Gliridae) in Eastern Europe and the Caucasus

Observations on a hybrid between the whooper swan (Cygnus cygnus) and the mute swan (Cygnus olor)
Pleiades Publishing Ltd - Tập 37 - Trang 759-767 - 2010
E. N. Panov, E. Yu. Pavlova
The swan obtained by hybridization between Cygnus cygnus and C.olor was delivered to the Moscow Zoo from the Leningrad Zoo in 1989. Between 2002 and 2004, it permanently remained with a female whooper swan in a large pond. The two swans behaved as a breeding pair, although the sex of the hybrid bird remained unknown. We observed no courtship displays addressed by the hybrid swan either to the fema...... hiện toàn bộ
Degradation of Phenols Formed during Lignin Pyrolysis by Microfungi of Genera Trichoderma and Penicillium
Pleiades Publishing Ltd - Tập 32 - Trang 445-449 - 2005
E. A. Karetnikova, A. D. Zhirkova
This work presents the data on the rate of utilization of phenols formed during lignin pyrolysis by micromycetes of the genera Trichoderma and Penicillium. Trichoderma strains utilized phenols at the concentration of liquid pyrolytic products of 0.5–1%, while Penicillium strains degraded over 50% phenols at the concentration of pyrolytic products of 2%. Micromycete cultures completely utilized phe...... hiện toàn bộ
Hierarchy of Factors that Determine the Timing of the Arrival of Passeriformes in the Ob Forested Tundra
Pleiades Publishing Ltd - Tập 47 - Trang 968-980 - 2021
V. N. Ryzhanovskiy, A. V. Gilev
This paper analyzes the factors that determine the timing of the spring arrival of passerine birds in the nesting area, i.e., the Lower Ob Region. For the period 1971–2015, a reliable negative trend to an arrival shift to earlier dates for seven out of 16 species, an unreliable shift for six species, and a positive trend for three species were found. Using cluster analysis, three groups of species...... hiện toàn bộ
Mechanism of enzymatic crosslinking of fibrinogen molecules
Pleiades Publishing Ltd - - 2008
M. A. Rozenfeld, V. V. Leonova, M. L. Konstantinova, S. D. Razumovskii
The mechanism of enzymatic covalent crosslinking of fibrinogen molecules under the effect of plasma transglutaminase (factor XIIIa) has been studied. Using the methods of elastic and dynamic light scattering combined with viscosimetry and electrophoresis of the reduced samples, it has been shown that fibrinogen oxidation strongly accelerates self-assembly of the covalently crosslinked fibrinogen p...... hiện toàn bộ
Analysis of Markers of Oxidative Damage of Neurons and Neuroinflammation in the Long-Term Period after Gamma Irradiation of a Mouse Head at Different Doses
Pleiades Publishing Ltd - Tập 49 - Trang 2467-2474 - 2023
E. Yu. Moskaleva, A. V. Rodina, Yu. P. Semochkina, O. V. Vysotskaya
Reactive oxygen species (ROS), which are formed under the action of ionizing radiation and inflammation factors, react with lipids and lead to the formation of toxic metabolites; one of the most active among them is 4-hydroxy-2-nonenal (4-HNE). It modifies cell proteins by lysine, histidine, and cysteine residues and disrupts their functions. The purpose of this research is to assess the number of...... hiện toàn bộ
Helminth Fauna of Black-Legged Kittiwakes (Rissa tridactyla, Laridae, Charadriiformes) in the Northern Part of the Kara Sea
Pleiades Publishing Ltd - Tập 50 - Trang 2147-2154 - 2024
V. V. Kuklin, M. M. Kuklina, A. V. Ezhov
The results of original studies on the helminth fauna of the black-legged kittiwake (Rissa tridactyla L.) (ten ad. and ten juv.) in the northern part of the Kara Sea (Severnaya Zemlya Archipelago and Wiese Island) carried out in the years 2019–2020 are presented. Eight species of helminths (one trematode, four cestodes, and three nematodes) have been registered. For the first time in seabirds in t...... hiện toàn bộ

The Co-Invasion of the Three Asteraceae Invasive Plants Can Synergistically Increase Soil Phenol Oxidase Activity
Pleiades Publishing Ltd - Tập 50 - Trang 467-473 - 2023
Youli Yu, Zhelun Xu, Shanshan Zhong, Huiyuan Cheng, Erhui Guo, Congyan Wang
The co-invasion of two or even more invasive plants in the same habitat can occur through invasion meltdown. Nevertheless, there is little progress in the ecological effects of the co-invasion of multiple invasive plants on soil enzyme activities. This study aimed to evaluate the effects of the co-invasion of three Asteraceae invasive plants (Conyza canadensis (L.) Cronq., C. sumatrensis (Retz.) W...... hiện toàn bộ
