Effect of background color on the pigmentation of Xenopus laevis larvae
12-06-2012 | V. V. Dzhapova, S. M. Starodubov, V. A. Golichenkov, Moscow University Biological Sciences Bulletin, 2012
Larvae of Xenopus laevis (stage 39, after hatching) were reared in the 0.95-L (10-cm height; 9.5-cm diameter) containers with all combinations of white, grey, and black color of bottom and walls (side background). The containers were kept in a closed box at 12-hours illumination per day. ...
Morphology and ultrastructure of the chemosensory sensilla of larval antennae in the Colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)
12-06-2012 | H. Farazmand, S. Yu. Chaika, Moscow University Biological Sciences Bulletin, 2012
The allocation, external morphology, and ultrastructure of various types of sensilla on the antennae have been studied in the larvae of the Colorado potato beetle (Leptinotarsa decemlineata Say) using scanning and transmission electron microscopy. It has been found that the larval antenna ...
Analysis of PDR1 retrotransposon insertions in the pea (Pisum Sativum L.)
12-06-2012 | Z. G. Kokaeva, A. V. Aleshin, Y. I. Berezov, Moscow University Biological Sciences Bulletin, 2012
We research polymorphism of PDR1 insertion grades, lines, and mutants of peas by means of seven pairs of specific RBIP-primers. Seven PDR1 insertions loci are identified in the studied forms of peas. We establish the high level of polymorphism of PDR1 retrotransposon inserts with primers ...
Effects of irradiation by the low-intensity electromagnetic field of the millimetric range on the Daphnia magna culture at various developmental stages
12-06-2012 | L. D. Gapochka, M. G. Gapochka, T. S. Drozhzhina, E. F. Isakova, A. S. Pavlova, O. B. Shavyrina, Moscow University Biological Sciences Bulletin, 2012
The influence of low-intensity electromagnetic irradiation and exposure to cadmium on survival and reproduction rates of daphnia in the process of their ontogenesis is investigated. The effects of the irradiation are clearly manifested in the toxicological experiments at coactions of the ...
Phenomenon of visiting in the pied flycatcher (Ficedula Hypoleuca Pall., Passeriformes, Aves) in the breeding period
12-06-2012 | T. A. Ilyina, Moscow University Biological Sciences Bulletin, 2012
Strange visitors to the pied flycatcher nest-boxes during the brood-rearing period were investigated in the Moscow oblast during 15 seasons. The total amount of visits was 760. Most of the visits (94%) were made by males and 5% and 1% were made by females and young birds with juvenile ...
Cytogerontological studies of biological activity of oregano essential oil
12-06-2012 | E. S. Alinkina, A. K. Vorobyova, T. A. Misharina, L. D. Fatkullina, E. B. Burlakova, A. N. Khokhlov, Moscow University Biological Sciences Bulletin, 2012
In order to clarify possible cytological mechanisms that underlie the beneficial effects of carvacrol-bearing essential oils on health and mental abilities, we studied one of them (oregano essential oil) in experiments on transformed cultured Chinese hamster cells. Possible cytotoxic or ...
Thermophilic anaerobic microbial communities that transform cellulose into methane (biogas)
12-06-2012 | E. A. Tsavkelova, M. A. Egorova, E. V. Petrova, A. I. Netrusov, Moscow University Biological Sciences Bulletin, 2012
The project is devoted to the screening of active anaerobic microbial communities which produce biogas via the decomposition of cellulose in thermophilic conditions (+55°C). Twenty-four samples were isolated from different natural and anthropogenic sources that contain desired microbial ...
Effects of intranasal administration of 5-hydroxytryptamine-modulin endogenous serotonergic modulator on rat behavior
12-06-2012 | O. I. Rudko, N. I. Sergeeva, L. A. Andreeva, R. A. Danilova, Moscow University Biological Sciences Bulletin, 2012
This article presents the study of the effects of 5-hydroxytryptamine-modulin—a poorly studied endogenous peptide (Leu-Ser-Ala-Leu)—which specifically interacts with 5-HT1B-auto- and heteroreceptors. Data obtained in the experiments on rats suggest prolonged anxiolytic and antidepressive ...
Monitoring the seasonal dynamics of ecologically tolerable levels for water regime, temperature, and pH in water objects of the Lower Don River
12-06-2012 | V. N. Maksimov, A. P. Levich, N. G. Bulgakov, A. V. Solov’ev, V. A. Abakumov, A. T. Terekhin, Moscow University Biological Sciences Bulletin, 2012
The feasibility of ecological standardization of physicochemical factors that do not refer to concentrations of polluting substances (water regime, water temperature, and pH) is confirmed. The opportunity of standardization is provided with the approach developed by the authors, which is ...
Microstructural characteristics of hair of pleistocene mummy of “Bilibino horse” Equus sp.
28-03-2012 | N. N. Spasskaya, O. F. Chernova, M. V. Ibraev, Moscow University Biological Sciences Bulletin, 2012
The microstructure of hair of all mummified horses found in Northeastern Siberia has been studied for the first time in a comparative aspect by means of light optical and electron microscopy techniques. The possibility of using hair of horse mummies of different geological ages for a ...
