The present study examined site-specific hamstring muscles use with functional magnetic resonance imaging (MRI) in elite soccer players during strength training. Thirty-six players were randomized into four groups, each performing either Nordic hamstring, flywheel leg-curl, Russian belt or the hip-extension conic-pulley exercise. The transverse relaxation time (T2) shift from pre- to post-MRI were calculated for the biceps femoris long (BFl) and short (BFs) heads, semitendinosus (ST) and semimembranosus (SM) muscles at proximal, middle and distal areas of the muscle length...

The purpose of this study was to assess the effect of two eccentric hamstring training exercises, Nordic hamstring (NHE) and Russian belt (RB), on lower limb strength and bilateral asymmetry using the Single Leg Hamstring Bridge (SLHB) test. Forty-seven elite junior soccer players (age 17.7±0.5 years, height 175.3±3.6 cm, body mass 68.1±7.4 kg) were randomized into one of three groups, the NHE group (n= 16), RB group (n= 15), or the control group (CG) (n= 16). The eccentric training intervention consisted of 27 supervised training sessions over 10 weeks...

The R3DR2 instrument performed measurements in the European Space Agency (ESA) EXPOSE-R2 platform outside the Russian "Zvezda" module of the International Space Station (ISS) in the period 24 October 2014-11 January 2016. It is the Liulin-type deposited energy spectrometer (DES) (Dachev et al., 2015a). Took place in November 2014, this was the first attempt to monitor a small solar energetic particle (SEP) event outside ISS using the Liulin-type DES (Dachev et al., 2015d). In this study, we describe the dosimetric characteristics of the largest SEP event, observed on 22 June 2015 with the R3DR2 instrument outside ISS...

Forest stand age plays a major role in regulating carbon fluxes in boreal and temperate ecosystems. Young boreal forests represent a relatively small but persistent source of carbon to the atmosphere over 30 years after disturbance, while temperate forests switch from a substantial source over the first 10 years to a notable sink until they reach maturity. Russian forests are the largest contiguous forest belt in the world that accounts for 17% of the global forest cover; however, despite its critical role in controlling global carbon cycle, little is known about spatial patterns of young forest distribution across Russia as a whole, particularly before the year 2000...

This study used functional magnetic resonance imaging (fMRI) to compare individual muscle use in exercises aimed at preventing hamstring injuries. Thirty-six professional soccer players were randomized into 4 groups, each performing either Nordic hamstring, flywheel leg curl, Russian belt or conic-pulley exercise. MRIs were performed before and immediately after a bout of 4 sets of 8 repetitions. Pre-post exercise differences in contrast shift (T2) were analyzed for the long (BFLh) and short head (BFSh) of biceps femoris, semitendinosus (ST), semimembranosus (SM) and gracilis (GR) muscles...

The identity of Scytalopus speluncae (Ménétriés, 1835) (Aves: Passeriformes: Rhinocryptidae), a tapaculo from southeastern Brazil, has been the matter of debate during the last eight years. A group of ornithologists considers that the nomen Scytalopus speluncae should be attributed to a species endemic to coastal mountains of southeastern Brazil, whereas another group considers it a species from the drier environments of another mountain belt in Minas Gerais, southeastern Brazil. Both research groups disagree on the identity of the still extant but damaged alleged holotype, deposited at the Zoological Institute of the Russian Academy of Sciences, St...

OBJECTIVE: In Russia, the high Road Traffic Injuries (RTIs) rate has been attributed to two well-known risk factors - the low rates of seatbelt and child restraints use and speeding. Despite the importance of understanding both speeding and seatbelt use patterns for the purpose of direct interventions or monitoring road safety situation, no study has assessed the current status of speeding among all vehicles and seatbelt wearing rates among all vehicle occupants in Russia. We are aware that alcohol is a known risk factor for RTI in the country however the work focused on seat belts and speed...

River valleys represent biologically rich corridors characterized by natural disturbances that create moist and barren sites suitable for colonization by native riparian plants, and also by weeds. Dams and reservoirs interrupt the longitudinal corridors and we hypothesized that this could restrict downstream weed expansion. To consider this "reservoir impediment" hypothesis we assessed the occurrences and abundances of weeds along a 315-km river valley corridor that commenced with an unimpounded reach of the Snake River and extended through Brownlee, Oxbow, and Hells Canyon reservoirs and dams, and downstream along the Snake River...

Russian space experiment "Matryeshka-R" was conducted in 2004-2005 to study dose distribution in the body of anthropomorphous phantom inserted in a spacesuit imitating container mounted on outer surface of the ISS Service module (experiment "Matryeshka"). The objective was to compare doses inside the phantom in the container to human body donned in spacesuit "Orlan-M" during extravehicular activity (EVA). The shielding function was calculated using the geometric model, specification of the phantom shielded by the container, "Orlan-M" description, and results of ground-based estimation of shielding effectiveness by gamma-raying...

Bashkortostan is a republic in the Russian Federation with a population of 4.1 million. As with other health behaviors, the prevalence of seat belt use is low, which may account in part for the very high rate of motor-vehicle-related mortality in this republic. The authors discuss the need and potential for translating seat belt promotion programming from other Russian regions and other countries to Bashkortostan. The authors conclude that current policies developed in other countries could work well in the republic, if they are enforced...

Through extended survey of mitochondrial DNA (mtDNA) diversity in the Nganasan, Yukaghir, Chuvantsi, Chukchi, Siberian Eskimos, and Commander Aleuts, we filled important gaps in previously unidentified internal sequence variation within haplogroups A, C, and D, three of five (A-D and X) canonical mtDNA lineages that defined Pleistocenic extension from the Old to the New World. Overall, 515 mtDNA samples were analyzed via high-resolution SNP analysis and then complete sequencing of the 84 mtDNAs. A comparison of the data thus obtained with published complete sequences has resulted in the most parsimonious phylogenetic structure of mtDNA evolution in Siberia-Beringia...

The extent of Antarctic pack ice in the summer, as charted from satellite imagery, decreased by 2.5 million square kilometers between 1973 and 1980. The U.S. Navy and Russian atlases and whaling and research ship reports from the 1930's indicate that summer ice conditions earlier in this century were heavier than the current average. Surface air temperatures along the seasonally shifting belt of melting snow between 55 degrees and 80 degrees N during spring and summer were higher in 1974 to 1978 than in 1934 to 1938...

Human ectoparasites, such as itch mites and the follicular mites Demodex brevis and D. folliculorum are notified on the territory of Moscow. The bird and rodent mites Ornythonyssus bacoti and the larvae of harvest mites may attack human beings indoors. The ticks Ixodes ricinus and I. persulcatus begin to inhabit the tree belts and environs of Moscow and other cities and towns. In the cities and towns of more southern regions of the Russian Federation, the red hen-mites Dermanyssus gallinae are also encountered and the ticks Rhipicephalus sanguineus and Ornithodoros papillipes begin to inhabit urban structures...

The tundra-taiga zone is considered not only as a natural ecotone, but as a unique fringe zone with socioeconomic peculiarities. This holistic approach enables us to analyze several significant types of human impacts (industrial impacts and those associated with renewable resources development, including traditional reindeer herding and human settlements) and their role in the displacement of the lesotundra zone. In Russia, there is much evidence of deforestation and ecosystem degradation in different regions of the lesotundra zone and the northern taiga which borders the lesotundra zone...

"This article examines the growing concentration of the elderly Jewish population of the U.S. in one metropolitan region of the Sun Belt. The principal data sources used are U.S. Census counts of the population with a Yiddish mother tongue or speaking Yiddish at home, as well as 1980 data on the population of Russian ancestry. The limitations of these measures are discussed and data from local community surveys also are presented. The data show that relocation of the elderly from the North, especially to South Florida, has been occurring since the 1950s and accelerated during the 1970s...

Autogenic (self-recovering) plant communities that need no transitional stages of succession for their recovery after damage are widespread in different areas of the Globe. They are typical for tundras, but also common in boreal forests, alpine belts, deserts and Mediterranean biomes. Such communities usually dominate the landscape. The authors examine in details the communities of cottongrass (Eriophorum vaginatum) wet tussock tundras of North-Eastern Asia and Alaska, the dryad (Dryas punctata) lichen dry patchy tundras of the same region and Scots pine (Pinus sylvestris) lichen-feathermoss forests on fluvial-glacial deposits of Fennoscandia and Russian Plain...

Measurements on board the Mir space station have been used to study the dose rate and the particle flux distribution in the inner magnetosphere. The measurements have been performed with the Bulgarian-Russian dosimeter-radiometer Liulin. The paper concentrates on the dynamics of the observed "new" and "second" maxima which were created after Solar Proton Events (SPE) in the 1989-1994 time. The "second" belt was first observed after the SPE on October 20, 1989, and the last observation was after the SPE on February 20, 1994...
