Authors: Rajasekaran Muthiah
Published: May 2019

The present study was conducted to evaluate the nephroprotective effect of a medicinal herb Costus pictus against doxorubicin-induced toxicity. Rats were divided into six groups and treated with doxorubicin and ethanol extract of the C. pictus. Doxorubicin was administered intraperitoneally with a single dose (4 mg/kg) per week for three weeks. The extract (200 or 400 mg/kg) was administered orally for 4 weeks to two doxorubicin groups. Significant changes of the serum kidney markers, albumin, urea, uric acid and creatinine, and glutathione peroxidase, glutathione–S-transferase, catalase, superoxide dismutase, reduced glutathione and lipid peroxides in the kidney of doxorubicin-treated rat were observed. Histological features were also severely affected. However, biochemical and histological changes in the extract-treated rat were non-significant, showing that the herb is nephroprotective. The effects were comparable to the anti-oxidant vitamin E.

Published: May 2019

A study was conducted on 300 farmers of five districts in north Bengal region, Bangladesh to know the socio economic status of farmers and their goat management system. We have found that 82% farmers are Muslim and 70% females are involved with goat farming. Survey showed that 47% goat farmer’s age range is (15-30 year) and 68% (46% female and 22% male) farmers are in primary standard level. Landless or small marginal farmers are involved with goat farming (37%). This study reflects that 54% farmer’s annual income is within 10,000 Tk whether 37% goat farmers earn between (10,000-20,000 Tk) per year. Only 9% farmers earn more than 20,000 Tk per year. 100% farmers in rural area rear their goat by semi intensive system; 82% and 18% farmers use kacha and paka floor respectively. 86% farmers supply concentrates feed with green grass whereas only 14% farmers do not supply any concentrate feed to their goat. Farmers supplied 2.63±0.05kg/day green grass, 60.00±5.86g/day concentrate and 0.62±0.03kg/day tree leaves per animal during lactation stage. Maximum (61%) farmers have more than 10 goat and 25% have 5-10 no. of goat. The body wt of buckling, doeling, buck and doe were 6.12± 0.04kg, 5.92± 0.06 kg, 8.45±0.10 kg and 7.44±0.04 kg respectively. Most of the farmers (84%) use natural and few farmers (16%) use artificial insemination to their doe. The incidence of pneumonia (61%), fever (43%), diarrhoea (42%) and anorexia (60%) are high in up to 1 month of age. Incidence of goat pox (58%) and alopecia (54%) are high in the age of above 9 months and ectoparasitic infestations (51%) are high in the age of (1-9) months. From above discussions we can concluded that Socio economic condition of farmers in rural area of North Bengal region is not so good. To enhance the production potential of the breed it is essential to introduce superior technologies and to create necessary facilities of improved practices in goat keeping.

Authors: Abramova S. , Zaidulina L. , Grachev D. , Iseev D. , Syatkina I.
Published: May 2019

Family health is an indicator reflecting the health status of the population. According to world statistics around the world about 15% of couples suffer from infertility. The proportion of infertile couples in the Russian Federation varies from 8 to 21%, while more than 55% of cases of infertility are due to impaired reproductive function. Inflammation of the fallopian tubes is one of the main causes of infertility. According to many authors in the Russian Federation, in groups of women up to 38 years old, inflammatory diseases of the pelvic organs occur from 20% to 50%. As a result of the development of damage to the fallopian tubes, the risk of developing tuboperitoneal infertility is high. According to statistics, every fifth woman has chronic inflammations, while 75% of them have adhesions in the small pelvis, in which the fallopian tubes are affected, not even having surgical treatment. All the above facts make the problems of tuboperitoneal infertility extremely low. This article presents the results of a clinical–factor analysis of tuboperitoneal infertility in women of reproductive age. Considered in detail the main factors that ensure the effectiveness and efficiency of the treatment in accordance with the algorithms of therapeutic and diagnostic tactics.

Authors: Sobolev I. D. , Shadrin A. N. , Rastorguev V. A. , Kozyreva D. A.
Published: May 2019

In the Schuchinskaya Zone of the Polar Urals granitoids of the Rechnoy and Yalya-Pe paleovolcanoes have been studied. They were mapped as Khoimpeysky Complex of Silurian age. In addition, granitoids of the Nganotsky-1 and Nganotsky-2 plutons mapped as Yunyaginsky Complex of Early Devonian age have been investigated. It was found that based on the mineral and chemical composition the rocks of all plutons studied correspond to island arc I-type granitoids. U-Pb (SIMS) concordant ages of zircons from granitoids of the Rechnoy and Yalya-Pe paleovolcanoes, and of the Nganotsky-1 pluton are 456±6, 454±4 and 463±3 Ma, respectively, which implies the existence of an island arc in the Schuchinskaya Zone as early as the Middle-Late Ordovician. Establishing the age of granitoids allows to refer volcanic rocks cut by plutons to Syadayskaya Formation, and to clarify the upper stratigraphic limit of its sedimentation as Middle-Upper Ordovician.

U-Pb dating (LA-ICP-MS) of detrital zircons from the upper Cambrian - lower Ordovician terrigenous deposits of Baidarata allochthone (northern part of the Polar Urals) is performed. Analysis of the youngest populations of detrital zircons suggests wide development of Uralides instead of Preuralides as it was believed before. The source of sediments for investigated Baidarata allochtone rocks was probably Bedamel’ island arc rather than Timan orogen. According to results of statistical analysis of detrital zircons data from coeval deposits of Arctic region, similarity of sedimentary provenances for Baidarata allochtone, Novaya Zemlya and Severnaya Zemlya archipelagos is observed.
Kinematics of the accommodation structures of the Baikal rift zone
Authors: Tevelev A. V. , Fedorovskiy V. S.
Published: May 2019

Rift systems are composed of a set of heterogeneous tectonic blocks, which deform under regional extension concertedly, but individually. Such coordination is achieved due to development along the borders of the blocks evolving ensembles of deformation structures, which, in one way or another accommodate discrepancies in the structural style between the separate domains of tension. Generally, quantity of structural ensembles segmenting the space of the rift zone is limited, and each of them has its own trend of tectonic development. This article analyzes the segmentation and evolutionary patterns of the Baikal rift zone in terms of transfer and accommodation zones accepted recently as standard descriptions for architecture of continental rift.

Patterns of spatial distribution of methane content across different landscapes were found. The highest concentrations of methane are found in alas deposits, the major role of methane in the conservation there goes to the moment of freezing the thermokarst lake draining. The difference in methane content in the sediments of the Late Pleistocene Ice Complex on the left and the right bank of the river Lena was identified. That is likely caused by the conditions of ice complex formation.
Forecast of the deposition of sulfate salts, taking into account the content of strontium, in the exploitation of oil deposits
Authors: Kireeva T. A. , Minikaeva R. I. , Anisimov L. A.
Published: May 2019

Based on the experience of developing an oil fieled on the Caspian Sea shelf, which was initially operated with injection of seawater into oil-bearing seams to maintain reservoir pressure, a forecast was made for the deposition of sulfate salts in reservoir conditions. The forecast of sulphate deposition is carried out in two ways: analytical calculations by the method of J.E. Oddo and M.B. Thomson and computer modeling. The prognosis took into account the strontium content in the reservoir waters of the deposit, which is usually ignored in oilfield practice. It has been established that computer modeling gives a more accurate prediction, in particular, considerably expands the temperature limits of anhydrite precipitation. The determination of the amount of potentially sulphate salts potentially found in computer simulations has shown that the mass of deposited calcium and strontium sulfates is large enough that it can significantly reduce the permeability of the reservoir.

Authors: Vishnevskaya V. S. , Kopaevich L. F. , Benyamovsky V. N. , Ovechkina M. N.
Published: May 2019

This article proposes a composite biostratigraphical scheme for the Upper Cretaceous of the East European Platform on the basis of the distribution in the sections of three groups of microfossils–foraminifers, both planktonic and benthic, radiolarians and nannoplankton. Most of the stages and subsustages boundaries are confirmed by macropalaeontological data. The most divided units are on benthic foraminifers and nannoplankton. The diversity of these microfossils and their constant presence in the sections made it possible to identify zones and subzones, while it is possible to subdivide only the beds by planktonic foraminifers and radiolarians. The most favorable stages in the development of plankton biota can be considered the Turonian-Coniacian interval, when the basins of the East European Platform felt the intensive influence of the warm waters of the Tethys ocean. The global Campanian coooling is clearly recorded, reflecting on the taxonomic diversity of all microfossil groups.

Published: May 2019

Composition and origin of Visean–Serpukhovian deposits of the Southern part of the Moscow syncline based upon generalizations of our own results and analysis of published and unpublished data were specified. The levels of karst-influenced rocks correspond to the shallowest biogenic carbonate organogeneous-clastic sediments of the initial and final phases of the eustatic cycle, i.e. the beginning of the transgression (the transgressive system of the tracts) and the end of the regression (the second half of the high-standing tract). In the karst cavities alluvial sands of the Oka river were found. A generalized model of the sequence was proposed and a sequential-stratigraphic interpretation of the studied section was carried out.

Authors: Davydova V. O. , Shcherbakov V. D. , Plechov P. Yu.
Published: May 2019

Zoned crystals record changes in magma evolution, such as injection of mafic magma into a shallow magma chamber, which often triggered to eruption of arc volcanoes. We applied diffusion chronometry for reverse zoned crystals of orthopyroxene from 6 eruptions of Bezymianny volcano during 2006–2012 years and showed correlation between time of injection of new magma and recorded seismicity. We descripted two type of Bezymianny volcano eruptions, which driven by different trigger mechanisms: 1) orthopyroxene rims formed during up to 3 years previous to eruption; 2) orthopyroxene rims formed during 0–2 months previous to eruption.

Published: May 2019

Data on the distribution of elements across the Pb-Zn section of the Gatsyrovskaya vein (Upper Zgid, North Ossetia, Russia) showed that during the formation of the vein significant changes in the spectra of rare-earth elements (REE) occur in ore samples. The sharp growth of ratios LaN/YbN, LaN/NdN, GdN/HoN, and GdN/YbN is confined to the vein intervals, where the maximum amount of ore components is deposited. A comparison of the REE spectra of ores with the characteristics of the spectra of the near-vein and host rocks suggests that the deposition of the vein material occurred from solutions whose compositions with respect to the REE varied with time. REE fractionation occurred due to the mobilization of components by hydrothermal solutions during their reaction with the host Paleozoic granites.

Paleomagnetic studies sariolyiski conglomerates of the Onega structure of the Karelian craton: Paleoproterozoic global remagnetization
Authors: Lubnina N. V. , Tarasov N. A.
Published: May 2019

As a result of paleomagnetic studies Sariolian 2,4–2,3 Ga conglomerates of the Onega basin of the Karelian protoctaton, two characteristic components of magnetization have been separated. Mean direction of the medium-temperature component has a heap distribution and coincides with mean direction of the Svecofennian remagnetization within the Karelian protocraton. The directions of high-temperature magnetization components isolated in conglomerates have a significant spread, which indicates the primary nature of this magnetization component. Two clusters of high-temperature components associated not only with the composition of protolites, but also with different conditions of rock transformations, including their fluid saturation, are distinguished.
The concept of cluster evolution minerageny in the Earth’s history
Authors: Krivitsky V. A. , Starostin V. I.
Published: May 2019

The new concept of cluster evolutionary mineralogy is based on the idea of the formation of the Earth from the primary stellar matter, which was preserved in the cores of the planets. The consequent destruction of it, as a result of the decay of heavy nuclear matter, leads to fragmentation of the substance until the appearance of superheavy elements with their further nuclear dissociation. As a result, a protomagma emerges, which enters the upper mantle in the form of plume flows. This process supports the reactions that result in the formation of chemical elements, minerals, ores and rocks, from which the upper mantle and the crust are formed. The processes of nuclear dissociation lead to the release of energy and the decomposition of matter, which initiates the growth of the earth's volume, its geotectonic activity, and the appearance of the hydrosphere and the atmosphere.
