Eddies in the Western Arctic Ocean From Spaceborne SAR Observations Over Open Ocean and Marginal Ice Zones
The Western Arctic Ocean is a host to major ocean circulation systems, many of which generate eddies that can transport water masses and corresponding tracers over long distances from their formation sites. However, comprehensive observations of critical eddy characteristics are currently not available and are limited to spatially and temporally sparse in situ observations. Here we use high‐resolution spaceborne synthetic aperture radar measurements to detect eddies from their surface imprints in ice‐free sea surface roughness, and in sea ice patterns throughout marginal ice zones. We provide the first estimate of eddy characteristics extending over the seasonally ice‐free and marginal ice zone regions of the Western Arctic Ocean, including their locations, diameters, and monthly distribution. Using available synthetic aperture radar data, we identified over 4,000 open ocean eddies, as well as over 3,500 eddies in marginal ice zones from June to October in 2007, 2011, and 2016. Eddies range in size between 0.5 and 100 km and are frequently found over the shelf and near continental slopes but also present in the deep Canada Basin and over the Chukchi Plateau. We find that cyclonic eddies are twice more frequent compared to anticyclonic eddies at the surface, distinct from the dominating anticyclonic eddies observed at depth by in situ moorings and ice‐tethered profilers. Our study supports the notion that eddies are ubiquitous in the Western Arctic Ocean even in the presence of sea ice and emphasizes the need for improved ocean observations and modeling at eddy scales
SELECTED CELLULAR IMMUNITY INDICATORS IN DIAGNOSTICS OF ACUTE MESENTERIAL ISCHEMIA
Background. The problem of early diagnosis of acute mesenteric ischemia is still relevant today. In this connection, it is of interest to search for a diagnostic marker of this pathological condition. Up to 80 % of all immunocompetent cells are localized in the intestinal mucosa. So, we can assume that the mesenteric channel occlusion can result in changes in the subpopulation structure of lymphocytes. The aim of the study is to analyse some parameters of the subpopulation structure of lymphocytes at various stages of acute mesenteric ischemia in the experiment. Materials and methods. The experiment was performed on 32 adult male rats - with an average mass of 200 g. The animals were divided into 4 equal groups. The first group was a control group. All other animals underwent laparotomy, blood sampling from the posterior vena cava, ligation of the mesenteric artery at the base of the mesentery root, suturing the wound. After 3, 6 and 8 hours, blood sampling, small bowel biopsy were performed in the second, third and fourth groups. The subpopulation structure of lymphocytes was assessed by direct immunofluorescence staining. Morphological material was stained with hematoxylin-eosin. Results. The complete occlusion of the cranial mesenteric artery was revealed to be accompanied by a decrease in the lymphocytes level, an increase in CD4/CD8 ratio. Conclusion. The data obtained were to develop a diagnostic method for acute mesenteric ischemia (Patent N 2552338, Russian Federation)

Audiovisual content analysis in the translation process
The article presents a comprehensive approach to the process of audiovisual translation that includes
application of multimodal analysis of semiotic codes present in audiovisual productions. The article
dwells on how the proposed approach can be applied to analyzing audiovisual productions for
different types of audiovisual translation. Due to its multimodal nature, an audiovisual production is
understood by the authors as an audiovisual text that combines image, sound and verbal means, that
is, different modes conveying meaning. The means of conveying meaning in an audiovisual
production include the visual non-verbal elements, visual verbal elements as well as audio non-verbal
and verbal elements. The priority of these means of meaning transfer and their interaction in
meaning generation differ significantly depending on the genre of audiovisual productions and the
specifics of the process of its creation
DIAGNOSTIC SIGNIFICANCE OF CERTAIN PARAMETERS OF “LIPID PEROXIDATION - ANTIOXIDANTS” SYSTEM IN THE FORECAST OF PURULENT-INFLAMMATORY COMPLICATIONS OF FOOT IN PATIENTS WITH PANCREATIC DIABETES
The research of content of primary and secondary (lipohydroperoxides, malondialdehyde) products of free radical oxidation of lipids in blood serum, and. indices of activity of antioxidant enzymes (glutathione peroxidase and. glutathione reductase) in 62 patients with pancreatic diabetes of type II. In 28 patients of them, the disease was complicated by suppurative inflammation of the foot. On the basis of these data we proposed a method of forecasting of the development of infectious complications in these patients at the stage of pre-clinical manifestations. This allows to make necessary pharmacological correction in the treatment of patients with pancreatic diabetes promptly to prevent the development of diabetic foot syndrome
Structure of air chemical pollution and environmental zoning for health assessment in large industrial centre
The problem of contamination of the lower layer of the atmosphere in Western Siberia remains relevant more than half a century. The territory of the city of Kemerovo, a major industrial center with well-developed coal-chemical complex is an obvious example of antropotechnogenous burden on the environment and the health of the population with its climatic and geographical, weather and economic features. The aim of the study was to evaluate the structure of chemical contamination during 2005-2011 years, their interaction and the allocation of the factors that determine the ecological zoning on the example of the city of Kemerovo to identify the role of chemical pollution on the health of the population. Factor analysis revealed two latentfactors that determine the structuring of chemical pollution of the city of Kemerovo, in accordance with the wind rose and the chemical nature of the contaminants. The research shows the negative influence of chemical pollution on the health of the population of the city of Kemerovo
Self-diffusion in a hyaluronic acid-albumin-water system as studied by NMR
Hyaluronic acid (HA) is an anionic biopolymer that is present in many tissues and can be involved in cancerous neoformations. HA can form complexes with proteins (particularly, serum albumin) in the body. However, HA structures and processes involving HA have not been extensively studied by NMR because the molecule's rigid structure makes these studies problematic. In the current work, self-diffusion of HA and bovine serum albumin (BSA), and water in solutions was measured by 1H pulsed field gradient NMR (PFG NMR) with a focus on the HA-BSA-D 2O systems at various concentrations of BSA and HA. It was shown that in the presence of even a small amount of HA, the self-diffusion coefficient (SDC) of BSA decreases. To explain this fact, three hypotheses were proposed and analyzed. The first one was based on the effect of slowing down of water mobility in the presence of HA. The second hypothesis suggested an effect of mechanical collisions of BSA with HA molecules. The third hypothesized that BSA and HA molecules form a complex where BSA molecules reduced in mobility. It was shown that the third mechanism is the most likely. The state of the BSA molecules in the BSA-HA-D 2O system corresponds to a 'fast exchange' condition from the NMR point of view: BSA molecules reside in the 'free' and 'bound' (with HA) states for much shorter time than the diffusion time of the PFG NMR experiment, 7ams. The fractions of 'bound' BSA molecules in the BSA-HA complex were estimated. Copyright © 2012 John Wiley & Sons, Ltd
