Digital fluorescence imaging techniques were employed to monitor changes in the cytoplasmic Ca2+ concentration and mitochondrial potential in fura-2 AM or rhodamine-123 loaded individual cerebellar granule cells during and following the Glu exposure. The data obtained suggests that the MD-induced blockade of the mitochondrial Ca2+ uptake and a reversal of(More)
Data obtained in studies of the nature of the correlation which we have previously observed [10,17] between mitochondrial depolarization and the level of disruption of Ca2+ homeostasis in cultivated brain neuronsare summarized. Experiments were performed on cultured cerebellar granule cells loaded with Fura-2-AM or rhodamine 123 to measure changes in(More)
Ontogenetic instability was studied in four rodent species (Ellobius talpinus, Microtus arvalis, M. rossiaemeridionalis, Mus musculus). It was measured by fluctuating asymmetry (FA) of 21 craniometric characters. Each species was represented by two populations differing in average level of chromosomic instability and in degree of anthropogenic influence.(More)
Taxonomic identification of arvicolines (Arvicolinae, Rodentia) based on dental characteristics without taking into account cranial, external, or other nondental features is an important task in neontology when studying the diets of carnivorous mammals and birds of prey and in Quaternary paleontology, biostratigraphy, and paleoecology. The morphological(More)
Fluctuating asymmetry (FA) of the mandible shape has been analyzed in bank voles from the zones affected by pollution from three copper smelters in the Urals. It has been shown that there is the necessity for a detailed analysis of the material, since the level of FA may depend on population parameters. Regardless of the pollution level, FA of the mandible(More)
In Craseomys rufocanus and Craseomys rex, the age-related and species differences in thickness and microstructure of the first lower molars (ml) have been identified and studied. The results suggest that the enamel dimensional and microstructural features may serve as additional indicators of the vole tooth evolutionary stage within a single phyletic(More)
Analysis of genetic diversity of burbot (Lota lota Linneus, 1758) mitochondrial control region (mtCR) haplotypes from geographically distant localities in the Ob-Irtysh River basin in comparison with distribution of known burbot haplotypes was conducted. mtCR fragments from burbot samples, obtained in two localities (longitudinal part of the Irtysh near(More)
The expediency of a modular approach to estimating fluctuating asymmetry (FA) of complex morphological structures was shown on the mandible of the bank vole (Clethrionomys glareolus Schreber, 1780) as an example. FA of the shape of two mandibular regions (modules) defined developmentally and functionally, was assessed by means of geometric morphometrics.(More)
181 Siberian flying squirrel (Pteromys volans L., 1758) is the only representative of the subfamily Pteromyii nae, occurring on the territory of Northern Eurasia. The habitats of this species are confined to the forest area (mainly conifers, partly the foresttsteppe and forr estttundra zones). The range of this species covers the territory of Eurasia from(More)
