We have conducted comparative analysis of the structure of the dorsal lips of the polychaete Eudistylia polymorpha from the family Sabellidae and the obturacula of Oasisia alvinae (Vestimentifera). It has been concluded that the obturacula of Vestimentifera are homologs of the dorsal lips of Polychaete from the family Sabellidae. It has been suggested that the head lobe of siboglinids of the subfamily Frenulata is homologous to the fused obturacula of Vestimentifera.

The paper presents the results of experiments with spore-forming bacteria and microscopic fungi performed in the framework of the Russian Research Program outside the International Space Station. It has been found that microorganisms not only survive in this extreme environment, but also retain reproductive ability. Moreover, most microorganisms exhibit an increase in biochemical activity and resistance to antimicrobial agents, specifically antibiotics. These findings are of obvious interest to ...

Here we report the first finding of a frenulate pogonophoran (Annelida, Siboglinidae) in the southern part of the Kara Sea. This finding was made in the Yenisei Gulf in the region of the highest methane concentrations, resulting from the degradation of permafrost under the influence of river flow. It has been suggested that pogonophorans are indicators of hydrocarbon manifestations of various genesis.

The analysis of phenetic diversity in Potanin Altai osman Oreoleuciscuspotanini from the Taishir Reservoir built in 2007 on the Zavkhan River (Great Lakes Hollow, Mongolia), revealed four morphologically discernible forms. Earlier, there were described two forms of O. potanini from the riverine part of the Zavkhan River and three forms in the lakes of the Great Lakes Hollow. The data of the study demonstrate similarity with cyclic morphogenesis in the closely related species Oreoleuciscushumilis...

The paper presents experimental data on the influence of a 1000-fold weakening of the Earth's magnetic field on the embryonic and postembryonic development of the Japanese quail in three generations. It has been shown that the weakening of the earth's magnetic field by a factor of 1000 affects the formation of blood vessels in Japanese quail embryos, in particular, causing a decrease in angiogenesis in seven-day-old embryos of both the first generation (F1) and the next two ones (F2 and F3). Pat...

The topography of ganglion cells in the retina of three neonatal bottlenose dolphins Tursiops truncatus has been studied in retinal wholemounts. Two areas of high ganglion cell density have been identified in the form of local spots in the temporal and nasal quadrants of the retina, near a horizontal diameter at a distance of 10-15 mm from the optical disk. The maximum density of ganglion cells in these areas on average for five preparations is 657 and 636 cells/mm(2) in the temporal and nasal q...

The human and animal osmoregulation system is aimed at stabilizing serum osmolality in order to maintain cell volume. It has been shown that the introduction of 5 mL water per 100 g of body weight into the stomach of rats decreases serum osmolality and the concentration of Na and Ca, but not K and Mg. The cascade system of osmotic homeostasis increases secretion of glucagon-like peptide-1 (GLP-1) and oxytocin, and decreases secretion of vasopressin, which reduces the osmotic permeability of coll...

The present study was aimed at the assessment of effects of anxiolytic Selank and nootropic Semax on the whole-brain resting-state functional connectivity (FC) of each of the predefined regions of interest (ROIs) in 52 healthy participants. The ROIs included amygdala (one of the key regions for the regulation of anxiety) and dorsolateral prefrontal cortex (DLPFC; the key region for executive functions, including working memory) in the right and left hemisphere. Resting-state fMRI was carried out...

Stocks of organic carbon in the soils and its resistance to biodegradation depend on a combination of external and internal determinants which control not only the decomposition, but also the stabilization of organic matter (OM). Soil OM stability was evaluated: 1) by specific mineralization rate (SpMinR) for the forest ecosystems located in various climatic zones of Eurasia (temperate, Mediterranean, and tropical) and 2) by the biological stability index (IBS), determined for the main soil type...

New fossils of Leporidae from the Lower Pleistocene deposits of the Taurida Cave in the central Crimea (Belogorsk district, Zuya village) are referred to Hypolagus brachygnathus (Kormos, 1930) and Lepus sp. Cooccurrence of Hypolagus and Lepus in the Early Pleistocene of Crimea is significant in terms of the question of the first appearance of Lepus in Europe, as well as the hypothesis of the competition with hares as one of the possible causes of extinction of Hypolagus.
