Evaluation of efficiency of using the enzyme preparation «Celloviridin Dx20» in the content of pig feed
Authors: Dejnega A. O. , Lesova V. O. , Anatsky A. S. 
Published: May 2016

One of the main problems in the feeding of farm animals is the low degree of digestion and assimilation of nutrients in the feed used in animal production. In the bodies of animals such as pigs and poultry enzymes and microflora which are necessary for breaking down cellulose and other polysaccharides of vegetable raw materials are absent, therefore they not only fail to be digested in the gastrointestinal tract, but also obstruct access of other digestive enzymes to the other feed components, in particular intracellular proteins. The only way to solve this problem is deliberate introduction of enzymes into food. Depending on the type and composition of the feed, amylolytic, proteolytic, cellulolytic enzyme preparations are used. The purpose of this work is to assess the effect of the enzyme preparation "Celloviridin Dx20" as a fodder component on the growth and biochemical parameters of young pigs. For this purpose, a scientific and economic experiment on feeding young pigs was conducted at the agro-industrial farm«Niva» (Novonikolaevka village, Dnipropetrovsk region), in which the enzyme preparation «Celloviridin Dx20», which promotes the breakdown of plant cell polysaccharides (cellulose, xylans) was introduced to a standard feed mixture used in swine husbandry. The composition of the ration consisted of 60% barley, 20% wheat and 20% of the protein-vitamin-mineral complex «ShenPigStart». The results of the experiment showed that the introduction into the feed mixture of the enzyme preparation at 100 g per ton helps to increase the body weight of pigs by 11.6% compared to the control, can increase the digestion rate of fibre (13.8%), protein and fat. These results can be explained by the mechanism of action of the enzyme complex, which consists in the hydrolysis of polysaccharides of plant cell walls in the feed in the digestive tract of pigs, the formation of digestable polysaccharides and the release of additional quantities of intracellular proteins. The result of these phenomena is also a positive trend in feed nitrogen assimilation in animals of the experimental group: a 19% decrease in the amount of physiological secretions and a 12.5% increase in nitrogen use. At the same time hematology (hemoglobin, erythrocytes, leukocytes), calcium and phosphorus metabolism remained unchanged. This shows that the preparation used does not accumulate in the body and gradually loses enzymatic activity, and under the influence of the pigs’ stomach proteases it is broken down into separate amino acids which are absorbed by the animals. The resulting stimulatory effect of using "Celloviridin Dх20" has not only physiological but also economic importance, as it helps reduce the time for the pigs to reach slaughter weight (close to 100 kg) by 11 days, and consequently, reduces feed intake and its costs in rearing pigs on farms. Therefore, it is advisable to use "Celloviridin Dх20" in swine husbandry.
Molecular and cellular mechanisms of profile changes of charged blood plasma free oligosaccharides in myeloproliferative disorders
Authors: Pismenetskaya I. U. , Butters T. D. 
Published: May 2016

Free oligosaccharides (FOS) are unbound to proteins or lipids structural analogs of their glycans. FOS appear as by-products of endoplasmic reticulum synthesis, cell control folding with endoplastic reticulum-associated degradation and lysosomal/endosomal breakdown of glycoconjugates. They may be either neutral or negatively charged depending on the way of their formation. Charged FOS appear during degradation of glycoconjugates in the lysosomal/endosomal system and are natural substrates for lysosomal sialidase-1. FOS are formed inside the cell but some of them can get into the extracellular space, and then into the blood and urine, where both neutral and charged structures were found. Secretion of charged FOS outside of the cell is most likely to be caused by the lysosomal exocytosis. The activity of neuraminidase-1 is known to be connected with the intensity of the lysosomal exocytosis. In our previous studies, it was found that HPLC-profiles of charged FOS were specifically changed in acute and chronic myeloproliferative blood disorders. The objective of this work was to analyze the molecular and cellular mechanisms of these changes and to test the hypothesis of their association with the activity change of lysosomal neuraminidase-1. Plasma samples of patients with acute and chronic leukaemia – polycytaemia vera, chronic idiopathic myelofibrosis, hypoplastic anaemia, myelodysplastic syndrome with transformation, acute lymphatic and acute myelomonocytic leukaemia – were collected for investigation. Plasma samples of practically healthy volunteers were obtained and used for comparison. After plasma deproteinization and FOS purification the oligosaccharides were labelled with anthranilic acid (2-AA), separated into the neutral and charged fractions with QAE Sephadex (Q25-120) chromatography and analysed using high-performance liquid chromatography (HPLC). Glucose unit values were determined following comparison with a 2-AA-labelled glucose oligomer ladder derived from a partial hydrolysate of dextran as an external standard. The data were collected and processed using Empower software. The charged FOS were digested with the sialidase from Arthrobacter ureafaciens. 2-AA – labelled free oligosaccharides from transferrin were used as an external standard for the structure decoding. In this paper, the changes in neraminidase-1 activity was first demonstrated on natural substrates, free oligosaccharides, in vivo. Chromatographic profiles of charged plasma FOS of patients with acute and chronic hematological malignancies revealed decreasing of neuraminidase-1 activity and increasing of the lysosomal exocytosis. Thus, chromatographic profiles of charged plasma FOS appeared to be a sensitive parameter of the lysosomal/endosomal status in normal or pathological states and to open up new prospects for their applications to the development of anti-cancer drugs designed to block the work of the lysosomal/endosomal system and monitoring of their action.

Estructuración y función del miocardio ventricular canino (Canis lupus familiaris): banda miocárdica ventricular
Authors: De Lavalle Rodrigo , Rendón Luis 
Published: May 2016

Introducción: actualmente se está presenciando la aparición de nuevas herramientas de diagnóstico y terapias para enfermedades del corazón, pero sin consenso científico serio sobre los interrogantes sobre la estructura normal del corazón y su función. La banda helicoidal miocárdica ventricular de Torrent-Guasp es el nuevo y revolucionario concepto en la comprensión global, en tres dimensiones de la arquitectura funcional del miocardio ventricular. Este concepto define la arquitectura de tejidos y fuerzas netas desarrollados en la masa ventricular.
Materiales y métodos: se utilizaron 36 corazones de caninos de diferentes pesos, razas y sexos, para demostrar la existencia de la banda miocárdica ventricular en el miocardio canino mediante una disección de tipo manual.
Resultados: la disección realizada mostró una gran tendencia hacia una estructura helicoidal continua, con una disposición longitudinal en las fibras miocárdicas ventriculares, formando una única banda muscular funcional, que empieza a la altura de la arteria pulmonar y termina a nivel de la aorta. Se identificaron los diferentes segmentos de la banda: el derecho (porcentaje de presentación 100%), el izquierdo (100%) respecto a las partes de la lazada basal, y en la disección de la lazada apexiana, el descendente (100%) y el ascendente (100%).
Conclusiones: se demostró la presentación de la banda miocárdica ventricular en el miocardio canino (Canis lupus familiaris) y se identificaron sus estructuras. Este es un nuevo concepto de la anatomía del miocardio ventricular canino, donde se evidencia macroscópicamente la entramada red de la doble helicoide. Según la teoría de Torrent Guast, el miocardio canino tendría la siguiente secuencia de contracción: contracción de la lazada basal, contracción del segmento descendente y ascendente de la lasada apexiana, y la expulsión y succión ventricular.

Educación retórica y filosófica: algunos vínculos entre Aristófanes y Eurípides
Authors: García Pérez David 
Published: May 2016

Considerando los juicios literarios y educativos de Aristófanes sobre el valor de la poesía, en general, y de la tragedia, en particular, se analizan algunos casos representativos en los que se evidencia la educación retórica plasmada en las tragedias de Eurípides. El contenido retórico puesto en acción a través de la dramaturgia griega era motivo de aprendizaje para los receptores. La retórica y su vínculo natural con la sofística, una forma de la filosofía, lleva al punto en el que los contenidos trágicos bajo la estructura retórica fueran también vehículo educativo en la gran escuela que significó el teatro ateniense.

Experimental Measurements and Correlation of K-value, Viscosity, and Density Data for Mixtures of Light to Heavy Solvents and Athabasca Bitumen with Applications of ES-SAGD Process
Authors: Zirrahi Mohsen , Hassanzadeh Hassan , Abedi Jalal 
Published: May 2016

Abstract
Alberta's oil sands reserve is one of the largest known hydrocarbon deposits. Current commercial recovery methods are steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS). These methods need a large amount of steam per unit volume of oil produced. This results in both high energy consumption and enormous impact on environment due to water treatment and greenhouse gas emissions. Expanding-Solvent SAGD (ES-SAGD) has been suggested to overcome the problems associated with these processes by associating solvent with steam injection. ES-SAGD not only reduces the environmental impacts but also increases the bitumen production efficiency. Therefore, ES-SAGD results in higher oil recovery with less production costs and reduced environmental impacts. The key pre-requisites for simulation and design of ES-SAGD process are the phase behaviour data consisting k-value, density, and viscosity of solvent-bitumen mixtures at high temperatures up to 250 °C and moderate pressures up to 6 MPa.
In this study, experimental k-value data of carbon dioxide and different hydrocarbon solvents in bitumen as well as experimental measurements of density and viscosity of solvent-bitumen mixtures are presented. Carbon dioxide and hydrocarbon solvents of methane to pentane are covered. The most of ES-SAGD projects are operated at temperatures close to 250 °C while the available experimental data in literature covers the temperature conditions up to 180 °C. Accurate correlations with solid thermodynamic background are presented to estimate the data at high temperature regions required for simulation of ES-SAGD process. These correlations are evaluated with the new measured experimental data.
The results showed significant difference between behaviour of light and heavy solvents in low and high temperature regions. At low temperature conditions, viscosity reduction of light solvents is more pronounced than heavy solvents while at high temperature regions heavy solvents are more effective. Comparison between the experimental data at high temperatures (240 °C) and the modelling results showed that the proposed correlations can be applied where the experimental data at high temperatures are not available. The experimental data and correlations in this study can be used for simulation and optimization of ES-SAGD processes in Alberta bitumen reservoirs.
Steam Circulation Strategies for SAGD Wells After Geomechanical Dilation Start-Up
Authors: Zhang Jing , Fan Yuxing , Xu Bin , Yang Baohong , Yuan Yanguang , Yu Yangfei 
Published: May 2016

Abstract
Dilation start-up has been widely used in Petro-China's Xinjiang oil field as a means of reducing start-up time and enhancing production from its "super" heavy oil reservoirs through the Steam-Assisted Gravity Drainage (SAGD) process. SAGD dilation start-up employs geomechanical dilation mechanisms to achieve these preferred results. Using a short-period of small-volume and high-pressure fluid injection, the dilation start-up facilitates the development of a dilated zone that vertically connects the SAGD well pair and is laterally uniform along the length of the well. This zone allows for more effective heat transfer to the inter-well area through convection than what is achieved through simple conduction during the conventional SAGD steam circulation start-up. In Petro-China's Xinjiang oil field, conventional SAGD start-up requires 10 to 12 months of non-productive steam circulation before oil production can begin. Wells treated with the SAGD dilation start-up can be converted to production after only 2 to 3 months of steam circulation.
This paper presents optimized steam circulation strategies which can be used with the dilation start-up treated SAGD well pairs. Numerical simulations are effectively integrated with field trials to derive best practices for steam circulation after the dilation start-up. The objectives are to get earlier and increased SAGD production as well as enhanced horizontal steam conformance. Operating parameters such as steam injection pressure, rate and pressure difference between the SAGD well pair were found to influence these objectives.
