Climate and environmental reconstructions of bolshezemelskaya tundra based on subfossil cladocera remains from kotovo lake (Kharbey system)
© SGEM2017. All Rights Reserved. The aim of the study was the analysis of subfossil Cladocera community of the Kotovo lake (Kharbey lakes' system, Bolshezemelskaya tundra) and the qualitative rating of the changes in it and in the region of study. The relevance of the work is associated with the increasing interest to the study of the climate change on the example of the North intact territories, along with the insufficient knowledge of the biota of the area being studied. The predominance of some species, zoogeography and biotopic attachments of identified taxa, shifts in qualitative consist of subfossil Cladocera taxocenoses, which took place during the lake evolution, were revealed in frames of the investigation. In the consist of Kotovo lake 17 taxa of subfossil Cladocera community were registered. The greatest number of the identified taxa refers to the Chydoridae family, while the representatives of the Daphniidae and Bosminidae families are found in smaller quantities. The lack of the obvious dominants in Cladocera community was established by using Lubarsky scale, subdominants are represented by Chydorus cf. sphaericus, Alona affinis and Bosmina (Eubosmina) sp. In the column of lake bottom sediments the change of the predominant species was registered: previously prevalent representatives of the genus Alona were replaced by Chydorus cf. sphaericus. The reconstruction of the climatic and environmental conditions of the geological past of the region being studied were produced according to the received results; and the changes in environmental conditions were matched with a particular period of geological time. Subfossil Cladocera taxonomic diversity of the lakes Kotovo and Bolshoy Kharbey (largest lake of Kharbey system) was compared. The comparative analysis of the modern structure of the Cladocera from the lakes of the Kharbey system with remains of Cladocera from bental sediments was carried out. The analysis of the received results indicates the eutrophication of the lake, the expansion of the littoral zone and reflects the climate warming
Subfossil cladocera from boreal lake gahkozero (The republic of Karelia, Russia) as paleoenvironmental proxies
© SGEM2017. All Rights Reserved. This investigation is aimed to determine general development patterns of the natural and climatic situations and lakes of the boreal zone in the later and postglacial time in the southeastern periphery of the Fennoscandian crystalline shield since the time of the last deglaciation. The analysis of the subfossil Cladoceran community was carried out on the basis of the 23 samples of Lake Gahkozero’ bottom sediments in the Republic of Karelia. In the subfossil Cladoceran community of the lake 42 taxa have been identified. The species inhabiting the zones of the Palaearctic and Holarctic are predominant in the lake; most of the identified subfossil remains relate to the pelagic species inhabiting the open part of the reservoir. The discovered subfossil remains of the phytophilous species (representatives of the genera Alona, Alonella, Pleuroxus) indicate the presence of the well-developed zone of macrophytes in the lake. The history of the development and the evolution of the lake is traced by the change of the taxonomic composition in the column of the bottom sediments. In the samples there is a dominance of two taxa - Bosmina (Eubosmina) cf. longispina и Chydorus cf. sphaericus, which replace each other during the evolution of the lake. The analysis of the variation in the diversity of the biotic groups is carried out using indices, determining the degree of species richness, diversity, and the dominance of Cladoceran communities. Results of statistical and stratigraphic analyses are presented
Results of subfossil Cladocera (Branchiopoda, Crustacea) analyses from bottom deposits of Lake Antyukh-Lambina (Kola Peninsula, Murmansk region).
The research is executed for restoration of climatic and ecological conditions of the past in the territory of the Kola Peninsula. The lake Antyukh-Lambina was once a part of the large lake Kolvitskoye and consequently, its ground "archives" contain information on its development, change of natural situations on a reservoir, change of climatic conditions of the region in general. The analysis the subfossil cladoceria of communities of ground deposits of the Kola Peninsula was not carried out and is of special interest itself in connection with the accruing anthropogenous loading in the region. In work results of the paleobiologic analysis of communities Cladocera in ground deposits of the lake Antyukh-Lambina are presented. It is established that in a reservoir palaearctic and holarctic taxons prevail, cosmopolitan distribution is peculiar to only 15% of the revealed taxons. Comparison of results with data of the hironomidny analysis is carried out. Information on researches of planktonic communities of lakes of the Kola Peninsula and its comparison with the data received during the analysis of the remains of Cladocera in ground deposits of the lake Antyukh- Lambina is provided. In work the indexes defining degree of specific wealth, variety and domination of communities the Crustacea are used, statistical and stratigraphic analyses are made. Results of the lithostratigraphic analysis are presented
Reconstruction of the history of a thermokarst lake in the Mid-Holocene based on an analysis of subfossil Cladocera (Siberia, Central Yakutia)
© 2017, Pleiades Publishing, Ltd. This paper presents the results of a cladoceran analysis of a sediment core with a lenght of 382 cm collected from a pingo in alas Khara Bulgunnyakh located in Central Yakutia. Based on the Cladocera analysis results, the formation of the lake had started during the Holocene climatic optimum ~6600 cal. yrs. BP. The analysis of changes in the species composition of subfossil cladoceran communities made it possible to identify, on the basis of cluster analysis, four statistically significant ecological zones. The period of optimal conditions for the Cladocera community is defined by a complex evened community structure and numerous cladoceran remains in the sediments accumulated between 6500 and 6000 cal. yrs. BP. The history of the thermokarst water body development and existence reconstructed on the basis of the subfossil cladoceran analysis was rapid and short
Disease-free and overall survival of patients diagnosed with HPV-associated or HPV-negative cervical cancer
The real-time PCR method is used to study scrapings of cervical epithelium and outer portion of the cervix in 116 patients aged 24–79 years with stage I–IV primary cervical cancer. The comprehensive survey included colposcopy, cytological and histological analysis, detection and genotyping of high-risk human papillomavirus. In 84 patients (72.4%) the presence of human papillomavirus (HPV) of high carcinogenic risk (HCR) is found, in 32 patients (27.6%) the presence of the virus has not been inspected in the tumor. A significant decrease in the survival rate as well as the prevalence of the worst prognosis for patients with HPV-negative cervical cancer are shown

Synthetic receptors based on calix[4]arene functionalized at the lower rim in molecular recognition of dicarboxylic, α-hydroxycarboxylic, and α-amino acids
New calix[4]arenes, di- and tetrasubstituted at the lower rim, with different functional groups were synthesized. They were studied as carriers of a series of dicarboxylic and α-hydroxycarboxylic acids through a liquid impregnated membrane. The calix[4]arenes under study are capable of molecular recognition of oxalic acid in the series of structurally similar dicarboxylic and α-hydroxycarboxylic acids. The regularities found make it possible to change purposefully the receptor ability of 1,3-disubstituted calix[4]arenes by variation of the nature of substituents
THE CURRENT STRESS OF EARTH'S CRUST IN THE TERRITORY OF UZBEKISTAN ACCORDING TO FOCAL EARTHQUAKE MECHANISMS
The current stress of Earth's crust in the territory of Uzbekistan has been studied using a focal earthquake mechanisms catalogue that includes the data provided by many authors. Stress reconstructions are based on the cataclastic analysis of displacements along fractures. For reconstructing the stress state at different depths of the crust in several seismically active regions of the study area, we consider a minimum number of earthquakes in a homogeneous sample equal to 6 and an averaging radius of 10 to 30 km within a single domain. The azimuths and dip angles of the principal stress axes, Lode – Nadai coefficients, geodynamic types of stress modes, relative (normalized to rock strength) values of maximum shear stresses, and effective pressure values are determined. Maps showing the spatial distribution of the studied parameters are constructed for both the entire seismically active layer and the depth layers. Stress fields are reconstructed and compared at two hierarchical levels based on the parameters of focal mechanisms of weak and moderate earthquakes (М≤4.5) and those of strong (М≥5.0) earthquakes. "Tectonic Stresses of Eurasia", the Internet resource created by IPE RAS, is used to visualize the stress field reconstructed from the data on strong (М≥5.0) earthquakes
