EFFECT OF PROPRANOLOL ON AEROBIC-HEMODYNAMIC SUPPORT OF PHYSICAL ACTIVITY IN PATIENTS WITH EFFORT ANGINA, POSITIVE ANTIANGINAL ACTION AND THE ABSENCE OF CLINICAL EFFECT AFTER PROPRANOLOL-BASED TREATMENT
Authors: Vasilyev A. P. , Streltsova N. N.
Published: April 2019

Aim. To analyze the changes in the aerobic-hemodynamic parameters during physical exercise in patients with effort angina administered with reference non-selective beta-blocker propranolol (Obsidan) with positive antianginal action and the absence of clinical effect after the drug intake.

Material and Methods. A total of 58 patients (mean age of 54.2 [48.5; 59.5] years) with effort angina of functional class II–IV were examined with spiro-veloergometry tests before and after administration of propranolol (Obsidan: manufactured by Isis Pharma GmbH, Germany) at a dose of 40 mg. At threshold physical activity the following parameters were assessed: oxygen consumption (VO2 ), specific oxygen consumption, cardiac index (CI), rate pressure product (RPP); total peripheral vascular resistance (TPVR), arteriovenous oxygen difference (a-vDО2 ) and mechanical work of the heart (HW).

Results. The efficacy of single-dose obsidian was observed in 58.6% of patients with angina (group 1); in this, tolerance to physical exercise increased from 50.0 [25.0; 75.0] W to 75.0 [50.0; 100.0] W. In the rest of patients (group 2), no antianginal effect was registered. At the first stage (at initial threshold physical activity level), administration of propranolol was characterized by saving pattern of heart function: statistically significant decrease in the heart rate, mean arterial pressure, CI and HW. This naturally resulted in reduction of myocardial oxygen demand (decrease in RPP from 163.0 [134.5; 218.5] U to 102.0 [90.0; 142.5] U; p<0.001) and predetermined the drug anti-ischemic action. At the second stage (maximum physical effort), an increase in the physical activity, caused by increase in VO2 from 738.0 [604.5; 1148.0] mL/min to 972.0 [774.5; 1458.0] mL/min, occurred due to higher oxygen extraction from peripheral blood (a-vDО2 increase; p<0.002). In group 2, despite the absence of an increase in tolerance to physical exercise, administration of propranolol was characterized by low RPP threshold i.e. the physical effort similar to the initial level was performed at a lower cardiac energy consumption.

Conclusion. Therefore, anti-ischemic effect of Obsidan was due to a decrease in theenergy expenditure of the cardiac function along with a limitation in the hemodynamic productivity efficiently compensated by an increase in the oxygen extraction from circulating blood during physical activity.

Authors: Shchekotova A. P. , Bulatova I. A. , Sosnin D. Yu. , Tretyakova Yu. I.
Published: April 2019

Aim. To study significance of platelet count and values of aspartate aminotransferase and tumor necrosis factor-α in the evaluation of the severity of liver fibrosis in chronic hepatitis C and for the development of fibrosis index calculation formula.

Material and Methods. The study included 70 patients with chronic hepatitis C end 30 healthy persons. Liver density was estimated by ultrasound elastography.

Results. The correlation analysis revealed strong relationships between the ultrasound elastography findings of fibrosis stage and the platelet count (r=0.83), aspartate aminotransferase (r=0.83), and tumor necrosis factor-α (r=0.81). The optimal separation points of laboratory tests for fibrosis exclusion were identified as follows: platelet count>270×109 /L (test sensitivity=96.2%), aspartate aminotransferase level<44 E/L (sensitivity=96.2%), and tumor necrosis factor-α concentration below 1.9 pg/mL (sensitivity=92.3%). The obtained values of laboratory parameters were used for calculation of the liver fibrosis index. The value of the fibrosis index ranging between 0 and 0.5 indicated the absence of fibrosis (stage F0), the value of the fibrosis index ranging between 0.6 and 2.5 corresponded to the moderate stage of fibrosis (F1-2), and the value of the fibrosis index>2.5 corresponded to the severe fibrosis/cirrhosis of the liver (F3-4) with diagnostic sensitivity of 83% and specificity of 78%.

Conclusion. Platelet count, the values of aspartate aminotransferase and tumor necrosis factor-α levels, fibrosis index, and laboratory test data can be used for ruling out fibrosis in chronic hepatitis C patients as well as for stratification of liver fibrosis stages.
VENOUS CONDUITS IN CORONARY SURGERY: OLD PROBLEMS — NEW SOLUTIONS
Authors: Vecherskiy Y. Y. , Manvelyan D. V. , Zatolokin V. V. , Shipulin V. M.
Published: April 2019

The introduction of autovenous coronary artery bypass grafting (CABG) marked the era of surgical revascularization in patients with coronary artery disease. It provided effective treatment for angina and significantly improved the long-term prognosis. Venous transplants today remain the most popular conduits in coronary surgery due to their availability, ease of harvesting, and the absence of length restrictions. Despite the advantages of autovenous CABG, the main disadvantage is the high incidence of venous graft failure, which represents an important and unresolved problem in cardiac and cardiovascular surgery. On the other hand, the traditional allocation of a large saphenous vein implies the dissection of soft tissues throughout the length of the isolated conduit. Traumatic dissection causes a long-lasting persistent pain syndrome after surgery, frequent abnormalities in  skin sensitivity, and a high incidence of wound complications in the lower extremities. These complications lengthen the period of rehabilitation of patients and worsen the quality of life. There is an approach of isolating the vein in a block with surrounding tissues to optimize the long-term functioning of the venous shunt, however, this technique is even more traumatic than the traditional method, and therefore its use is limited in practice. On the other hand, the introduction of minimally invasive methods of isolation allowed to reduce the incidence of wound complications and to improve the cosmetic result, but there is no convincing data regarding the effect on the consistency of shunts in the long-term postoperative period. The problems associated with the use of venous conduits in CABG are multifaceted, and their solutions are necessary to improve the effectiveness of surgical revascularization.

Published: April 2019

Aim. In order to optimize the diagnosis of pneumonia by including lung ultrasonography in the diagnostic algorithm for pneumonia, the main ultrasound signs of inflammatory infiltration of the lungs were identified, depending on the form of morphological substrate, and the capabilities of ultrasound examination in monitoring pneumonia were evaluated.

Material and Methods. A total of 96 patients were admitted to hospital by emergency to rule out/to confirm pneumonia based on X-ray diagnosis of this pathology in 81 persons. Ultrasonic examination was performed in all patients at a day of admission to hospital. Dynamics in inflammatory infiltrate was evaluated in 55 patients at days 3–4, 7, and 10–14 of hospital stay.

Results. The ultrasonic signs of inflammatory infiltrate were found in 55 of 96 patients with prevalent ultrasound pattern of pleuropneumonia (n=48; 50%) and bronchopneumonia in a smaller number of patients (n=7; 8.6%). The results of ultrasonography showed the low sensitivity (69.7%) and significantly high specificity (100%) rates of the method in detecting pneumonia. Positive dynamics in ultrasonic monitoring of pneumonia was detected in the overwhelming number of patients (n=45; 81.8%) at day 3 of hospitalization. Negative dynamics (n=3; 5.5%) was observed at days 3 and 7 of the study.

Conclusion. Ultrasonic study may be considered a useful step in the diagnostic algorithm for patients with pneumonia as this method provides additional information for an attending physician and does not involve adverse effects of ionizing radiation on patient’s body. Since the ultrasonic data on positive and negative dynamics of pneumonia were received ahead of the results of standard control radiography and were verified by further clinical and radiological observations, the role of ultrasonic monitoring of the inflammatory infiltrate was essential for evaluation of the efficacy of antibiotic therapy at earlier time.
MORPHOLOGICAL AND PERFUSION PREDICTORS OF DISTANT CEREBRAL DISORDERS IN CARDIAC SURGERY PATIENTS
Authors: Portnov Yu. M. , Semenov S. E. , Syrova I. D. , Sigitov I. V.
Published: April 2019

Aim. To assess the preoperative morphological state of the brain and the state of cerebral circulation in patients referred for coronary bypass surgery to identify predictors of long-term cerebral disorders.

Material and Methods. The study included 33 male patients, divided into 2 groups according to the presence or the absence of distant neurological complications 5 years after surgery. All patients underwent non-contrast computed tomography of the brain and perfusion computed tomography. Computed tomography was repeated 5 years after surgery.

Results. The perfusion indices in all measurement zones in patients of the two groups did not significantly differ. Significant differences in width of the third ventricle and ventricular-cranial index between patients of groups 1 and 2 were not identified. The incidence rates of leukoaraiosis significantly differed: leukoaraiosis was detected significantly more frequently in group 2 (78% of cases) than in patients of group 1 (31%), p=0.0455.

Discussion. The dimensions of the brain cavity system and the preoperative state of the microcirculatory blood flow were not predictors of long-term postoperative neurological disorders. Five years after surgery, patients of group 2 showed clinical and morphological signs of past ischemic changes, which were not detected in patients of group 1 suggesting that leukoaraiosis was an unfavorable prognostic indicator of postoperative cerebrovascular disorders in the long-term period.

Conclusion. When referring a patient with the presence of morphological manifestations of cerebral microangiopathy in the form of the leukoaraiosis phenomenon for cardiac surgery, these patients should be considered at risk requiring administration of the necessary set of measures for the prevention of long-term cerebral disorders.

Religious moderation discourse in plurality of social harmony in Indonesia
Authors: Kawangung Yudhi
Published: April 2019

The study of religious tolerance this century has been entering the culmination point of saturation, in which it is no longer viewed relevantly with technology 4.0 or it is generally called millennium generation. Technology development is directly proportional to social life because humans enter the digital era in which the actualization and self-existence are prioritized. Therefore, in social interaction, it often makes friction and horizontal conflict and even social media felt more concerned about. Tolerance is gradually degraded in its implementation because it is assumed that tolerance givers have a higher level (majority) than the recipient of tolerance (minority). In this case, the tolerance model needs contextual modification, namely religious moderation as a fundamental of more acceptable social interaction among citizens and netizens.

Надежное обеспечение потребителей нефтепродуктами по приемлемым ценам традиционно является одной из наиболее обсуждаемых проблем российской экономики, в том числе потому, что напрямую затрагивает интересы большого количества автолюбителей, а косвенно (через систему межотраслевых связей) – практически всего населения страны. Интерес к этой теме особенно возрастает в периоды дефицита нефтепродуктов и/или резкого роста цен на них. Но «топливный» вопрос – это лишь наиболее отчетливо видимая часть тех проблем, которые накопились в российском нефтегазовом секторе и в целом в отечественной экономике. В статье обозначен спектр отраслевых проблем, без решения которых кризисы в сфере топливообеспечения будут продолжаться с незавидной периодичностью и впредь, их решение будет усугубляться необходимостью все больших усилий и затрат.
Концессии в теплоснабжении: инвестиции вместо субсидий
Authors: Нефёдкин В. И. , Фадеева О. П. , Гинзбург Д. Р.
Published: April 2019

В статье рассматривается широкий круг проблем теплоснабжения в РФ и в Новосибирской области. Исследуются возможности и ограничения, связанные с применением концессий в качестве инструмента повышения эффективности и надежности теплоснабжения прежде всего в тех населенных пунктах, которые не привлекательны для крупных энергетических компаний. На основе изучения опыта концессий в теплоснабжении в Новосибирской области и интервью, проведенных с инициаторами и участниками проектов, авторы делают выводы как о первых практических результатах, так и о сопутствующих проблемах. В качестве примера рассматриваются проекты модернизации систем централизованного теплоснабжения в р.п. Маслянино и г. Обь. Первые результаты реализации данных проектов показали, что инвестиции со стороны федерального и регионального бюджетов позволили практически полностью отказаться от субсидирования теплоснабжающих организаций. Вместе с тем возможности тиражирования этого опыта из-за ряда институциональных и экономических причин ограничены. Наибольшие риски для потенциальных концессионеров связаны с практикой регулирования тарифов, базирующейся на «экономически обоснованных затратах», и высокими транзакционными издержками передачи в эксплуатацию частной стороне систем централизованного теплоснабжения, ранее обслуживаемых муниципальными унитарными предприятиями. Авторы предлагают использовать новые механизмы финансирования концессий в сфере теплоснабжения, которые могут существенно повысить привлекательность подобных проектов для частных инвесторов и заметно уменьшить потребность в текущих субсидиях из регионального и местных бюджетов на поддержку убыточных теплоснабжающих организаций.

Inquiry and Research: A Relational Approach in the Classroom
Authors: Smith Daniel
Published: April 2019

The spirit of inquiry within research, which encourages curiosity and wonder, is a promising approach to information literacy instruction. This sort of commitment to wonder and the spirit of inquiry also has a lot of theological promise and potential. As we participate in the formation of present and future faith leaders, promoting the value of wonder and the spirit of inquiry cannot be overstated as an invaluable skill. We also must remain reflective, humble, and imitative in our practice. The author presents this approach in a very compelling, approachable way, and this resource is a very succinct introduction or reminder. Librarians who are engaged in teaching research will likely find this approach promising and provocative.

Authors: Dorn-Medeiros Cort M. , Dykeman Cass , Bergquist Timothy
Published: April 2019

Evidence suggests that women who report same-sex partners may be at particular risk for experiencing negative health effects from alcohol and tobacco use. Using data pooled from the results of the 2008–2013 New York City Community Health Survey, this study used multiple regression analyses to examine the predictability of annual household income, age, race, and history of depression on frequency and quantity of alcohol and tobacco use within a total sample of women who have sex with women (WSW). Age and history of depression were statistically significant predictors of alcohol use in WSW, and race was a statistically significant predictor of tobacco use with non-Hispanic White respondents.Results of this study provide greatly needed insight into possible risk factors for alcohol and tobacco use among a significantly understudied population. Results also provide strong encouragement for counselors to inquire about sex and sexuality regardless of client self-identified sexual orientation.
Crowdsourcing punishment: Individuals reference group preferences to inform their own punitive decisions
Authors: Son Jae-Young , Bhandari Apoorva , FeldmanHall Oriel
Published: April 2019

Justice systems delegate punishment decisions to groups in the belief that the aggregation of individuals’ preferences facilitates judiciousness. However, group dynamics may also lead individuals to relinquish moral responsibility by conforming to the majority’s preference for punishment. Across five experiments (N=399), we find Victims and Jurors tasked with restoring justice become increasingly punitive (by as much as 40%) as groups express a desire to punish, with every additional punisher augmenting an individual’s punishment rates. This influence is so potent that knowing about a past group’s preference continues swaying decisions even when they cannot affect present outcomes. Using computational models of decision-making, we test long-standing theories of how groups influence choice. We find groups induce conformity by making individuals less cautious and more impulsive, and by amplifying the value of punishment. However, compared to Victims, Jurors are more sensitive to moral violation severity and less readily swayed by the group. Conformity to a group’s punitive preference also extends to weightier moral violations such as assault and theft. Our results demonstrate that groups can powerfully shift an individual’s punitive preference across a variety of contexts, while additionally revealing the cognitive mechanisms by which social influence alters moral values.
Fill Factor Effects in Highly-Viscous Non-Isothermal Rubber Mixing Simulations
Authors: Ahmed I. , Poudyal H. , Chandy A. J.
Published: April 2019

A finite volume technique in a commercial computational fluid dynamics (CFD) code is employed in this study to simulate transient, incompressible, non-Newtonian and non-isothermal rubber mixing. The simulation processes are conducted in a two-dimensional(2D) domain, where a mixing chamber partially-filled with rubber is equipped with a pair of two-wing non-intermeshing counter-rotating rotors. The main objective is to assess the effect of different fill factors of rubber on dispersive and distributive mixing characteristics by simulating 15 revolutions of the rotors rotating at 20 min−1. 50%, 60%, 70%, 75%, 80% and 90% are the six different fill factors chosen for the study. An Eulerian multiphase method has been applied to solve for the two different phases, rubber and air. The non-Newtonian property of rubber is handled using the shear rate dependent Carreau-Yasuda model, along with an Arrhenius function to include the temperature dependency. In addition to the governing equations related to the conservation of mass, momentum and energy, the volume of fluid (VOF) method is chosen to track the interface between air and rubber. With regard to the results, flow patterns, thermal distributions, viscosity behavior and volume fraction are analyzed for the different fill factors. In addition, dispersive and distributive mixing behavior is also assessed in detail using Lagrangian statistics, such as mixing index, cumulative distribution of maximum shear stress, cluster distribution index (CDI), scale of segregation (SOS) and length of stretch (LOS), calculated from massless particles. Both the Eulerian and Lagrangian results showed that fill factors between 70% and 80% presented the most reasonable and efficient mixing scenario, and also exhibited the best dispersive and distributive mixing characteristics combined.
Structural and Optical Characteristics of Laser Irradiated CdSe/PVA Nanocomposites
Authors: Nouh S. A. , Abou Elfadl A. , Benthami K. , Alhazime A. A.
Published: April 2019

Nanocomposites of polyvinyl alcohol (PVA) and Cadmium selenide (CdSe) were fabricated by ex-situ casting technique. CdSe nanoparticles were prepared by thermolysis under the flow of nitrogen. Rietveld refinement of x-ray data showed that the prepared CdSe adapts cubic zinc blend structure with a lattice parameter 6.057 Å and a mean grain size of 2 nm. Samples from CdSe/PVA nanocomposite have been exposed to infrared (IR) laser fluences in the range 0–19.6 J/cm2. The effect of IR laser radiation on the structural and optical properties of CdSe/PVA has been investigated using XRD and UV-vis spectroscopy. UV/VIS absorption spectra confirm the formation of hybridized film CdSe/PVA nanocomposite with refractive index in the range of 1.4119–1.8621 (at 700 nm). Also, the laser radiation reduces the optical energy gap from 4.1 to 3.43 eV which could be attributed to the increase in structural disorder of the irradiated CdSe/PVA nanocomposites due to the formation of coordination reaction between OH of PVA and CdSe nanoparticles. This means that the laser radiation led to a more compact structure of CdSe/PVA nanocomposite and causes proper dispersion of CdSe nanoparticles in the PVA matrix. Further, the Commission Internationale de E'Claire (CIE units x, y and z) methodology was applied in this work for the description of colored samples. The color intensity ΔE, which is the color difference between the non irradiated sample and the irradiated ones, was increased from 11.40 to 30.57 with increasing the laser fluence up to 19.6 J/cm2.

Published: April 2019

Housing and sanitation as one of the most essential human needs has always been at the top of human demands. Smart houses are among the latest achievements of the housing industry in the present era which have been taken into consideration in recent decades. The research method of this paper is descriptive-analytic. In the first part the paper deals with the definition of intelligent housing fields components functions. Also by objective observation and completion of the questionnaire information about the intelligent housing indices was collected. Using the AHP hierarchy technique the degree of physical vulnerability of residential units in the first district of Tehran has been determined; the results show that many residential areas are exposed to severe vulnerability. Also in order to answer the research hypothesis 30 professors and experts of the housing department were analyzed by the path analysis technique.

The results of path analysis show that all factors have a direct and significant effect on reducing the vulnerability of urban housing. Separating direct and indirect effects of variables on reducing the vulnerability of urban housing shows that the safety and security agent with the highest value of 0.892 has the most direct, a positive and significant effect on reducing the vulnerability of urban housing. The remarkable thing about this factor is that the indirect effect of this agent through the factor of well-being and comfort is 0.863 which is very significant; in other words the factor of safety and safety through the factor of welfare and comfort will significantly reduce the vulnerability of housing. Also the direct effect of the comfort and comfort factor of 0.422 and energy savings of 0.398 significantly contribute to reducing the vulnerability of urban housing.

Published: April 2019

El objetivo de este artículo es explicar de qué manera el juego se constituye en una estrategia que posibilita el desarrollo del lenguaje en su función comunicativa, mediatizadora y reguladora en un niño de cuatro años con trastorno del espectro autista (TEA), desde el ámbito de la educación inclusiva en la transición de la edad preescolar a la escolar. Esta investigación es de diseño pretest-postest. La intervención se fundamentó en la estrategia del juego y tuvo una duración de tres años. El proceso interventivo requirió de la realización de ajustes específicos en el aula a la que asistía el estudiante con TEA, considerando sus necesidades de desarrollo. Estos ajustes se dirigieron al uso de diversas herramientas culturales en el ámbito educativo (dibujos, llavero de imágenes, gestos) por parte de la docente para ayudar al niño a comprender la importancia de aprender a comunicarse con los otros estudiantes. Los resultados demostraron que, en el juego, la función comunicativa posibilita el desarrollo de las funciones mediatizadora y reguladora del lenguaje en el niño en el marco de una educación inclusiva. Además, el juego como estrategia ayuda en el desarrollo de conductas prosociales o altruistas.
Innovación educativa como elemento de la doble responsabilidad social de las universidades

Cada vez es más usual que las universidades del mundo se sumen al esfuerzo internacional para mejorar la educación y brindar servicios de calidad para la mayor cantidad de jóvenes. Sin embargo, es lamentable cuando el aumento de la calidad pudiera verse mermado por una falta de interés en emprender y adoptar procesos de innovación en sus modelos educativos, quedando rezagados en lo que ofrecen. Hoy por hoy, no basta con repetir modelos que muchas veces resultan obsoletos para las nuevas necesidades de la industria 4.0; es necesario innovar. El presente artículo busca hacer una reflexión sobre la necesidad de la innovación educativa como parte de la responsabilidad social que tienen las universidades con la comunidad, al considerar que no basta con ser responsables desde un enfoque asistencialista si no se hace lo que intrínsecamente les corresponde al brindar educación de calidad a las futuras generaciones.

Laidunnusstrategiat ja niiden vaikutus emolehmätilan tuotantoon ja talouteen

Maailmalla emolehmätuotanto on jo pitkään perustunut laiduntamiseen. Suomessakin laiduntamista on pidetty ja osittain pidetään edelleen yhtenä kannattavan emolehmätuotannon kulmakivenä. Laiduntamisella luodaan myönteistä imagoa emolehmätuotannolle. Se luo kuluttajalle kuvan eettisestä tuotantotavasta. Laiduntaminen on lihantuotannossa yksi tärkeistä markkinointikeinoista myydessä lopputuotetta suoraan kuluttajalle. Luonnollinen tuotantotapa ja eettisyys ohjaavat kuluttajia yhä enemmän elintarvikeostoissaan. Viime vuosina keskustelua on kuitenkin herättänyt se, onko perinteiseen malliin järjestetty laiduntaminen tilalle kuitenkaan kannattavin vaihtoehto. Ajatusta perustellaan pääasiassa laitumen alhaisemmaksi jäävällä satotasolla ja sen myötä tilan karkearehuomavaraisuuden heikkenemisellä. Laiduntamisen imago- ja eläinten hyvinvointihyödyt ovat kiistattomat, mutta ne voidaan saada käyttöön myös perinteisestä poikkeavilla laidunnusmenetelmillä. Savonia-ammattikorkeakoulussa tehtiin yhdessä A-Tuottajien hallinnoiman ja Luonnonvarakeskuksen osatoteuttaman Tuottava itäsuomalainen naudanlihantuotanto-hankkeen kanssa selvitys, jossa kuvattiin neljä erilaista emolehmätilojen laidunnusmallia ja selvitettiin, kuinka laidunnusstrategia vaikuttaa tilojen tuotantoon ja talouteen, työssä tarkasteltujen tuotantotekijöiden ja kustannustenkautta. Työssä luotiin laidunnusmallit, joiden pohjalta emolehmätilalliset voisivat selvittää, millainen laidunnusstrategia toimisi heidän tilallaan. Case-tilat valittiin esihaastattelemalla noin kahtakymmentä emolehmätilallista, joiden joukosta valittiin neljä tutkimukseen parhaiten soveltuvaa tilaa. Näillä neljällä tilalla käytiin ja tehtiin laajempi haastattelu. Haastattelulla selvitettiin, kuinka laidunnus tilalla on käytännössä toteutettu ja millaisia vaikutuksia sillä on tarkastelussa oleviin kustannuksiin ja tuotantotekijöihin. Työssä esiteltävät laidunnusstrategiat ovat intensiivinen laiduntaja, tyypillinen laiduntaja, osittaislaiduntaja sekä ulkotarhassa jaloittelija, joka ei laidunna eläimiä ollenkaan. Kustannuksia ja eläinterveyden tuotantotekijöitä vertaillessa laiduntamaton tila ei suurimmassa osassa tarkastelukohteista päässyt yhtä hyviin tuloksiin laiduntavien tilojen kanssa. Kokonaistyöaikaa tarkastellessa tuloksiin vaikutti laidunkautta enemmän sisäruokintakauden työmenetelmät. Tiloilla, joilla sisäruokintakauden työmenetelmät ovat aikaa vieviä, tilat hyötyvät enemmän laidunkauden työmäärää vähentävästä vaikutuksesta.
