ORIGIN OF MELTING ANOMALIES IN THE JAPAN-BAIKAL CORRIDOR OF ASIA AT THE LATEST GEODYNAMIC STAGE: EVOLUTION FROM THE MANTLE TRANSITION LAYER AND GENERATION BY LITHOSPHERIC TRANSTENSION

At the latest geodynamic stage that is characterized by forces and processes of the last 90 Ma the lithosphere of Asia has been reactivated due to four main force factors: 1) mantle melting anomalies, 2) subduction-related interaction between the Pacific plates and the continental eastern margin, 3) convergent interaction between India and the continental southern margin, and 4) quasiperiodic orbital variations of the Earth. The starting point of the latest geodynamic stage [Rasskazov, Chuvashova, 2013] is consistent with the change of the Earth’s rotation due to the resonant interaction of its orbit with the orbit of the Mars in the time interval of 87–85 Ma [Ma et al., 2017].At the latest geodynamic stage that is characterized by forces and processes of the last 90 Ma the lithosphere of Asia has been reactivated due to four main force factors: 1) mantle melting anomalies, 2) subduction-related interaction between the Pacific plates and the continental eastern margin, 3) convergent interaction between India and the continental southern margin, and 4) quasiperiodic orbital variations of the Earth.

Рифты, орогены, кратоны и глобальная тектоника: введение в проблему

A key role in developing the Earth theory is played by comparative studies of orogens, rifts, and platforms in the equatorial, middle and high latitudes of Asia and the adjacent Arctic regions. The modern shape of the planet’s triaxial asymmetrical cardioid ellipsoid results from its latest (Late Phanerozoic) geodynamic evolution that began in Arctic and then commenced in Asia. At this stage, mechanisms of the lithosphere extension and compression, combined with extension, were launched in Arctic and Asia, respectively. The special issue of Geodynamics & Tectonophysics presents papers on this topic.В развитии теории Земли ключевую роль играют сравнительные исследования орогенов, рифтов и платформ в экваториальных, умеренных и высоких широтах Азии и сопредельной Арктики. Современная форма трехосного асимметричного кардиоидального эллипсоида на планете обусловлена ее новейшей (позднефанерозойской) геодинамической эволюцией, начавшейся в Арктике, а затем – в Азии. На новейшем геодинамическом этапе в Арктике был запущен механизм растяжения литосферы, в Азии – механизм сжатия, сочетающегося с растяжением. Cтатьи по этой тематике представлены в специальном выпуске журнала «Геодинамика и тектонофизика»

Models of the organization of the judicial system: the experience of Russia and foreign countries

This article provides an overview of the organization of the judiciary in various countries. Firstly, attention is drawn to the legislative framework on the basis of which the system of courts in a particular state is built. Secondly, the conclusion is drawn that there are three models of the organization of the judiciary: decen-tralized; moderately centralized; strongly centralized bathroom. Examples of states in which distinguished models of the organization of the judiciary operate are given. Particular attention is paid to the place of the Russian model in the classification of judicial systems according to the degree of centralization of the judiciar

ПЕРИОДИЗАЦИЯ СОВРЕМЕННЫХ И ПОЗДНЕПЛЕЙСТОЦЕН-ГОЛОЦЕНОВЫХ ГЕОДИНАМИЧЕСКИХ И ПАЛЕОКЛИМАТИЧЕСКИХ ПРОЦЕССОВ

Based on comparative analyses of spatial and temporal patterns of high- and medium-potassic basaltic eruptions in the Central Mongolia and marine survey records of Sr isotopes, it is revealed that the start of the recent geodynamic stage in the Central Mongolia correlates with the starting point of its global manifestation, which gives an evidence of a close relationship between magmatic occurrences in the region under study and processes of global convergence. The magmatic occurrences are considered as representing the recent geodynamic evolution of the past 90 Ma with milestones of ~66, 40–37, ~32 and 17–15 Ma ago. Global changes, except those ~32 Ma ago, are shown in marine records of Sr isotopes. The Late Plestocene – Holocene natural and climate setting is reconstructed from radiocarbon datings of various geological and paleobiological objects. Changes of the natural environment and climate of the Northern hemisphere are plotted with account of strong magma eruptions, attacks of asteroids and meteorites, changes of lithological compositions of sedimentary complexes and species compositions of fauna at the given time interval.  Приведены результаты исследований, выполненных в лаборатории изотопии и геохронологии и лаборатории кайнозоя ИЗК СО РАН в рамках проектов СО РАН: ИМП № 77 «Изучение закономерностей проявления опасных природных процессов в исторически обозримом прошлом для разработки основ прогноза их поведения на ближайшие десятилетия» (РК 01201282598) и Пр. VIII.69.1. «Факторы, определяющие изменение среды и климата Центральной Азии в кайнозое». На основе сравнительного анализа пространственно-временного распределения высоко- и умеренно калиевых базальтовых извержений в Центральной Монголии и морских записей изотопов Sr выявлено соответствие начала новейшего геодинамического этапа в Центральной Монголии точке отсчета его глобального выражения, свидетельствующее о тесной связи магматических событий региона с глобальными процессами конвергенции. Эти магматические события рассматриваются как представительные для новейшей геодинамической эволюции литосферы за последние 90 млн лет, в ходе которой определена важнейшая роль рубежей ~66, 40–37, ~32 и 17–15 млн лет назад. Происходившие глобальные изменения, за исключением рубежа ~32 млн лет назад, запечатлены в морских записях изотопов Sr. Из анализа радиоуглеродного датирования различных геологических и палеобиологических объектов восстановлена природно-климатическая обстановка позднего плейстоцена и голоцена. Построена кривая, отражающая изменения природной среды и климата Северного полушария с учетом проявления мощных вулканических извержений и астероидно-метеоритных атак, изменение литологического состава осадочных комплексов и видового состава фауны на заданном временном интервале.

GeneNet in 2005

The GeneNet system is designed for collection and analysis of the data on gene and metabolic networks, signal transduction pathways and kinetic characteristics of elementary processes. In the past 2 years, the GeneNet structure was considerably improved: (i) the current version of the database is now implemented using ORACLE9i; (ii) the capacities to describe the structure of the protein complexes and the interactions between the units are increased; (iii) two tables with kinetic constants and more detailed descriptions of certain reactions were added; and (iv) a module for kinetic modeling was supplemented. The current SRS release of the GeneNet database contains 37 graphical maps of gene networks, as well as descriptions of 1766 proteins, 1006 genes, 241 small molecules and 3254 relationships between gene network units, and 552 kinetic constants. Information distributed between 16 interlinked tables was obtained by annotating 1980 journal publications. SRS release of the GeneNet database, the graphical viewer and the modeling section are available at http://wwwmgs.bionet.nsc.ru/mgs/gnw/genenet/

Новейшая геодинамика Центральной Азии: первичные и вторичные мантийные расплавные аномалии в контексте орогенеза, рифтогенеза и движения-взаимодействия литосферных плит

A comprehensive model for deep dynamics in Asia has been developed from the data on the evolution of melting anomalies in the context of lithospheric plate motions, interactions, orogeny, and rifting. The key components of our model are the primary (transition layer) and secondary (upper mantle) melting anomalies (Gobi, Baikal, and North Transbaikalia; and Hangay, Sayan, and Vitim, respectively). It is inferred that the primary melting anomalies originated at the beginning of the latest geodynamic stage (ca. 90 Ma) as a result of the transition layer distortion by lower mantle flows. Such primary anomalies were caused by avalanche collapses of the slab material that had been stagnated under the closed fragments of the Solonker, Ural-Mongolian paleooceans and the Mongol-Okhotsk Bay of Paleopacific. The secondary melting anomalies occurred due to the Early-Middle Miocene structural reorganization in the Pacific-Asian and Indo-Asian interaction zones. The primary melting anomalies governed the spatial distribution of forces and processes of the latest geodynamic stage. The secondary melting anomalies resulted from the lithospheric motions relative to the primary anomalies and provided for the development of orogeny and rifting. The Baikal-Mongolian corridor of asthenospheric flows was limited by the lateral zones of convergent interactions between India and Asia in the southwest, and North America and Asia in the northeast. In these lateral zones, Late Phanerozoic paleoslabs and ascending mantle fluxes were revealed in the transition layer, as well as in the upper mantle, without any destruction by the asthenospheric flows.По данным об эволюции расплавных аномалий в контексте орогенеза, рифтогенеза, движения и взаимодействия литосферных плит развита обобщающая модель глубинной динамики Азии, в которой важнейшую роль играли первичные Гобийская, Байкальская и Северо-Забайкальская расплавные аномалии переходного слоя и вторичные Хангайская, Саянская и Северо-Байкальская расплавные аномалии верхней мантии. Предполагается, что первичные расплавные аномалии формировались в начале новейшего геодинамического этапа (около 90 млн лет назад) в результате нарушения переходного слоя нижнемантийными потоками из-за лавинного обрушения слэбового материала, который стагнировал под закрывшимися фрагментами Солонкерского, Урало-Монгольского палеоокеанов и Монголо-Охотского залива Палеопацифика, а вторичные получили развитие в связи с процессами раннесреднемиоценовой структурной перестройки в зонах Тихоокеанско-Азиатского и Индо-Азиатского взаимодействия. Первичные расплавные аномалии служили в качестве главного фактора пространственного распределения усилий и процессов новейшего геодинамического этапа, а вторичные явились следствием движения литосферы относительно первичных аномалий и способствовали развитию орогенеза и рифтогенеза. Японско-Байкальский геодинамический коридор сдерживался латеральными зонами конвергентного взаимодействия Индостана и Азии на юго-западе и Северной Америки и Азии на северо-востоке. В латеральных зонах сдерживания позднефанерозойские палеослэбы и восходящие мантийные потоки были зафиксированы в переходном слое и верхней мантии без разрушения астеносферными потоками

Isolation, characterization and molecular cloning of Duplex-Specific Nuclease from the hepatopancreas of the Kamchatka crab

<p>Abstract</p> <p>Background</p> <p>Nucleases, which are key components of biologically diverse processes such as DNA replication, repair and recombination, antiviral defense, apoptosis and digestion, have revolutionized the field of molecular biology. Indeed many standard molecular strategies, including molecular cloning, studies of DNA-protein interactions, and analysis of nucleic acid structures, would be virtually impossible without these versatile enzymes. The discovery of nucleases with unique properties has often served as the basis for the development of modern molecular biology methods. Thus, the search for novel nucleases with potentially exploitable functions remains an important scientific undertaking.</p> <p>Results</p> <p>Using degenerative primers and the rapid amplification of cDNA ends (RACE) procedure, we cloned the Duplex-Specific Nuclease (DSN) gene from the hepatopancreas of the Kamchatka crab and determined its full primary structure. We also developed an effective method for purifying functional DSN from the crab hepatopancreas. The isolated enzyme was highly thermostable, exhibited a broad pH optimum (5.5 – 7.5) and required divalent cations for activity, with manganese and cobalt being especially effective. The enzyme was highly specific, cleaving double-stranded DNA or DNA in DNA-RNA hybrids, but not single-stranded DNA or single- or double-stranded RNA. Moreover, only DNA duplexes containing at least 9 base pairs were effectively cleaved by DSN; shorter DNA duplexes were left intact.</p> <p>Conclusion</p> <p>We describe a new DSN from Kamchatka crab hepatopancreas, determining its primary structure and developing a preparative method for its purification. We found that DSN had unique substrate specificity, cleaving only DNA duplexes longer than 8 base pairs, or DNA in DNA-RNA hybrids. Interestingly, the DSN primary structure is homologous to well-known Serratia-like non-specific nucleases structures, but the properties of DSN are distinct. The unique substrate specificity of DSN should prove valuable in certain molecular biology applications.</p
