Authors: Sokolov D. A , Lyuboshevskiy Pavel A. , Levshin N. Yu , Zhemchugov A. V , Kuptsova L. V
Published: September 2020

The effectiveness of postoperative analgesia may be determined by genetic characteristics of patients that affect the pharmacodynamics and pharmacokinetics of drugs. In particular, as a result of the metabolism of tramadol by isoenzyme of cytochrome P-450 is formed O-desmethyltramadol having higher affinity to mu-opioid receptors. The paper explored the effectiveness of analgesia based on tramadol in 48 patients after endoscopic gynecological surgery depending on the presence/absence of polymorphisms of CYP2D6 gene.It was found that 15 patients with polymorphisms С100Т and G1846A had more intensive postoperative pain, which was accompanied by activation of the sympathetic nervous system. Determination of these polymorphisms may be useful to select the optimal postoperative analgesia.

Authors: Sokologorskiy S. V , Sheina M. A , Zvyagin A. A , Orudzheva S. A.
Published: September 2020

Background: As diabetes takes on pandemic proportions, more than 1000000 patients undergo some kind of low limb surgery yearly. While peripheral hemodynamic state during such kind of surgery in these patients has been studied quite well in various anesthesia technique, the central hemodynamic state and systemic oxygen delivery remain unclear. Objective: To evaluate a single-injection nerve block vs spinal anesthesia influence on central and peripheral hemodynamics and systemic oxygen delivery during low limb surgery in diabetes patients. Design: A prospective cohort study. Setting: Federal scientific centre. Patients: 31 diabetes patients during elective low limb surgery under single-injection nerve block and spinal anesthesia. Intervention: Patients were randomly allocated to one of the two groups according the anesthesia technique - either a single-injection nerve block or spinal anesthesia. Main outcome measures: Levels of cardiac index mean arterial pressure, oxygen delivery index, glycaemia and VAS scores were evaluated on five time points: 24 hours before surgery, during surgery, before discharging from operating room, 6 and 24 hours after surgery respectively. Results. Levels of cardiac, systemic vascular resistance and oxygen delivery indexes together with mean arterial pressure had no statistically significant differences in time points in group received single-injection nerve block technique. These patients had full pain relief even in 6 hours after surgery and 24 hours after surgery their VAS pain scores were not more than 3. A single-injection nerve block technique shown its prolonged pain-relief effect with minimal systemic side effect. In patients with spinal anesthesia technique statistically significant decreases of mean arterial pressure and systemic vascular resistance with parallel cardiac index increase in time points were observed. In 6 hours after surgery, their VAS pain scores were not more 2 and 24 hours after surgery not more than 4. Spinal anesthesia once more shown to be reliable and effective but not long-acting intraoperative anesthesia technique. Additional postoperative pain relief necessity is a specific spinal technique problem. Conclusion: The results of the study showed that a single-injection nerve block technique due to its low influence on systemic circulation is more preferable in patients with compromised circulation system, while spinal technique may be used in patients with no heart and vascular disturbances. More clinical investigations must be done to evaluate central hemodynamic changes during these types of anesthesia in diabetes patients more precisely.

Published: September 2020

Introduction: It is assumed that one of the factors of high incidence of postoperative complications in postpartum women with obesity is intra-abdominal hypertension (IAH). The aim of the work was to evaluate the dynamics of intra-abdominal pressure (IAP) in postpartum women with obesity, depending on the method of postoperative analgesia. The study involved 136 patients divided into 4 groups: control group - initial BMI of 18.5 to 24.9 kg / m2, II of group - patients with obesity I degree (n = 40); Group III - obesity II degree (n = 35); Group IV - III degree obesity (n = 21). All patients were divided into two subgroups - postoperative analgesia with opioids and epidural analgesia (EA). We investigated the timing of reversal of intestinal motility, passage of gas, nausea severity, dynamics IAP and compliance of the anterior abdominal wall. Postoperative dynamics IAP is associated with motor function of the intestine, which is dependent on the initial level of IAP. Paresis intestine often diagnosed at a rate of more than 95% of IAP percentile - for the control group of patients more than 20 mm Hg for patients with obesity more than 23 mm Hg., recorded before the operation. With the development of paresis bowel IAP dynamics within three postoperative days it was practically absent (Δ IAP = 2,55 ± 1,28 mm Hg). Postoperative EA, compared with the use of narcotic analgesics, significantly reduces IAP during the first postoperative day, which prevented the development of their intestinal paresis (RR 0.47; 95% CI: 0,24-0,83), reduced incidence of postoperative nausea (RR 0.47; 95% CI: 0,18-1,21), allows you to quickly reduce the level of IAP in the subsequent days of the postoperative period (59.7%, compared with the effect of opioids). The method of postoperative analgesia affects the dynamics of IAP. EA is the method of choice for postoperative analgesia in postpartum women with obesity and the initially high level of IAP.

About the value of the national language of science (part no. 2)
Authors: Donskikh Oleg A.
Published: September 2020

The article examines the process of formation of national languages of science in the history of European culture, starting from the XIV century. The conditions that contributed to this process are considered. First, an absolute prerequisite for the emergence of the language of science is the flourishing of national literature, both in poetry and in prose. A significant role is played by the development of the university education, where teaching philosophy (including the philosophy of nature), i.e. the ability to freely work with abstract concepts, was a prerequisite for the transition to specialization in theology, law, and medicine. Printing, in turn, not only dramatically increased the number of readers belonging to the middle class,but also contributed to the development of national languages. Finally, since the fourteenth century in Europe, literary societies have sprung up in the courts of lords with the aim of improving the native language. These societies are gradually supplemented by associations and academies whose members are interested in science and are not limited by the statutes of universities. The article considers the formation of the scientific language in Russia in the XVIII-XIX centuries. This is a process that took almost two centuries, starting from the philological studies of V. E. Adodurov, V. K. Trediakovsky and M. V. Lomonosov. The role of Russian poets and writers, who greatly enriched the vocabulary of the Russian language, have provided it with freedom and flexibility, the importance of such organizations as the Assembly of translators, the Free Russian Assembly, the Russian Academy, etc. and, of course, the work of hundreds of scientists is of inestimable importance.

Published: September 2020

Scientific and technological renewal of agricultural production and the related improvementof management and organization of the economy are considered in the articleas the main means of strengthening its economy. At the same time, it contributes to solvingsocial problems common to the city and the village, such as increasing the availability offood, reducing retail food prices, balancing the use of labour resources in the city and rural areas, solving problems of greening production and improving the environment in the placesof residence. Ultimately, the goal is to improve the quality of life.The article argues the need to intensify the transition of the agricultural industry of Russiainto the direction of innovative development. The main possible directions of modernizationof its economy related to mastering of high-performance latest technologies of productionand management have been investigated.At the same time, consideration is given to the possibility of weakening the negative sides ofthe divergent objectives of the functioning of the two subsystems of social development –high-intensity production and preservation of natural resources, including those used in agricultureas the main means of production. This task will help to solve the mastery by agriculturalenterprises of the latest technologies of production and environmental conservationmethods of farming.State assistance to rural producers in the acquisition and development of high-tech meansof production, the development of the technology market are seen as improving the currentpractice of supporting agriculture (limited mainly to dating low-value production), and increasingits importance for the growth of production and social development of rural areas.Modernization of agricultural production is presented as part of the general innovative restructuringof the economy of the national economy.
The effects of instructional language on feedback requests and skill acquisition
Authors: Barros Joao , Mora Erika , Becker Andrea
Published: September 2020

BACKGROUND: Self-controlled feedback enhances skill acquisition. However, the pattern and frequency of feedback requested varies and impacts learning. Given that instructions that increase learner’s feelings of autonomy, an explanation for self-controlled feedback benefits, have also been shown to enhance learning, it is possible that instructional language modulates feedback requests and consequently skill acquisition. AIM: We investigated if autonomy-supportive language leads to different pattern and increases frequency of feedback requests and skill acquisition. METHOD: Forty-two participants (22 women and 20 men) were assigned to a controlling or autonomy supportive instructions group. After each trial, participants were asked “Do you NEED feedback?” or “Do you WANT feedback?”, respectively. The task consisted of pressing a specific sequence of 5 computer keys in 1200ms. Then, participants completed 24hrs retention/transfer tests without feedback. During transfer participants performed the same sequence in 1500ms. RESULTS: Repeated measure ANOVAs indicated participants in the WANT group requested more feedback than participants in the NEED group. Both groups distributed feedback evenly throughout acquisition. No differences in performance in acquisition or in retention/transfer tests were identified.INTERPRETATION: Autonomy supportive instructional language increased feedback requests but not learning. Including measures of feelings of autonomy is encouraged to clarify the mechanisms underlying these findings.

Cell Communications among Microorganisms, Plants, and Animals: Origin, Evolution and Interplays
Authors: COMBARNOUS Yves , NGUYEN Thi Mong Diep
Published: September 2020

Cellular communications play pivotal roles in multi-cellular species, but they do so also in uni-cellular species. Moreover, cells communicate with each other not only within the same individual but also with cells in other individuals belonging to the same or other species. These communications occur between two unicellular species, two multicellular species, or between unicellular and multicellular species. The molecular mechanisms involved exhibit diversity and specificity, but they share common basic features which allow common pathways of communication between different, and sometimes very different species. These interactions have been made possible by the high degree of conservation of the basic molecular mechanisms of interaction of many ligand-receptor pairs in evolutionary remote species. These inter-species cellular communications played crucial roles during Evolution and must have been positively selected, particularly when collectively beneficial in hostile environments. We think that communications between cells did not arise after their emergence but was part of the very nature of first cells. Synchronization of populations of non-living protocells through chemical communications may have been a mandatory step towards their emergence as populations of living cells and explain the large commonality of cell communication mechanisms among microorganisms, plants, and animals.
Do Peer Influence Corporate Firms? Evidence from Working Capital Management Practices
Authors: Farooq Umar , Ahmed Jaleel
Published: September 2020

Working capital management requires a careful attention by the corporate managers because it plays an important role in corporate stability. Social belongingness of managers induced them to learn from their society, colleagues and from overall industrial movement. They also learn from their peers which have more strategical efficiency. In line with these arguments, the objective of current study is to explores the peer influence on corporate working capital management practices. To making analysis, ten-years data (2009-2018) of non-financial publicly listed firms at PSX were collected and the cash conversion cycle (CCC) uses as a proxy variable of working capital management (WCM). To estimate the regression, an econometric technique named the Generalized Method of Moments (GMM) was used. The empirical findings suggest the significant impact of peer WCM on corporate WCM. It also suggests the significant impact of other variables that determine the WCM. This study recommends social learning policy to corporate managers. They can learn from their peers to manage the working capital. Most previous studies discuss the peer influence on investment decisions, corporate cash holding and financing policy, etc., but no study explores such a relationship specifically in the Pakistani non-financial sector data set.

Geology, Geochemistry and Geochronology of the Gold Mineralization Hosting Syenite, Tulu Kapi, Western Ethiopia: A Review
Authors: Oljira Temesgen , Warkisa Geleta
Published: September 2020

The Neoproterozoic (900-600 Ma) Arabian Nubian Shield is an example of Precambrian plate tectonics and arc accretion. The Western Ethiopian Shield (the southern extension of ANS) is geo-tectonically a characteristic of lower grades of Metavolcano-sedimentary sequences of ANS intruded by associated felsic granitoid and mafic bodies and at the same time it is contained of gneisses rocks of the MB. The Gold mineralization and alterations initiating throughout the Tulu Kapi syenite are in the form of in enechelon vein arrays and related structures, which are controlled by conjugate shear zones in the syenite and steep N-S striking structures. The earliest recorded deformation and alterations revealed the syenite albitization which is the one hosting for gold mineralization and it has been widely overprinted by multistage hydrothermal system that appears to have been controlled mainly by veins, crackle zones, fractures and minor breccia zones. Primary gold mineralization displays spatial and temporal relationship with Tulu Kapi syenite and the Kapi gabbro, both of which host gold mineralization, are 738.3±2.6 Ma and 699.5±2.7 Ma period, respectively, in a volcanic arc subduction syn-collisional tectonic setting by the fractionation of underplated, LREE-enriched basaltic magma with substantial crustal input to possible crustal melting. The underplated basaltic magma had been sourced from LREE-enriched mantle by subduction of sediment laden crustal slabs at a subduction zone. Fractional crystallization involved formation of Ca-rich plagioclase, which continually reacted with hydrothermal fluids to more fractionated Na-rich plagioclase, forming the gold mineralization hosting altered (albitized) syenites. The Pan-African orogeny, and associated regional metamorphism and magmatism, generated large-scale movements of gold and base metal-bearing fluids in the crust, channelized along complex fractures into regional NE-SW foliation in Ethiopia (e.g., western Ethiopia). However, these gold-rich alkalic magmas are so modified by crustal processes that evidence of their genetic relationship with gold become obscured. The primary ore mineral assemblage of quartz veins and veinlets, and associated mineralised syenite within Tulu Kapi area consists of pyrite, galena, chalcopyrite, hematite, and gold. The major and trace element composition of ore- forming fluids from the mineralised vein, barren and granitic intrusion is still largely unknown, yet could provide important and more direct evidence for the fluid source(s). This is vital in establishing a direct genetic link between syenite and other granitoid intrusion, and gold mineralization.
Computational Micro-Macro Analysis of Impact on Strain-Hardening Cementitious Composites (SHCC) Including Microscopic Inertia
Authors: Tamsen Erik , Curosu Iurie , Mechtcherine Viktor , Balzani Daniel
Published: September 2020

This paper presents a numerical two-scale framework for the simulation of fiber reinforced concrete under impact loading. The numerical homogenization framework considers the full balance of linear momentum at the microscale. This allows for the study of microscopic inertia effects affecting the macroscale. After describing the ideas of the dynamic framework and the material models applied at the microscale, the experimental behavior of the fiber and the fiber-matrix bond under varying loading rates are discussed. To capture the most important features, a simplified matrix cracking and a strain rate sensitive fiber pullout model are utilized at the microscale. A split Hopkinson bar tension test is used as an example to present the capabilities of the framework to analyze different sources of dynamic behavior measured at the macroscale. The induced loading wave is studied and the influence of structural inertia on the measured signals within the simulation are verified. Further parameter studies allow the analysis of the macroscopic response resulting from the rate dependent fiber pullout as well as the direct study of the microscale inertia. Even though the material models and the microscale discretization used within this study are still simplified, the value of the numerical two-scale framework to study material behavior under impact loading is shown.
Export Product Diversification, Poverty and Tax Revenue in Developing Countries
Authors: Gnangnon Sena Kimm
Published: September 2020

The current paper has examined the effect of both export product diversification and poverty on non-resource tax revenue in developing countries. The analysis has used an unbalanced panel dataset of 111 countries over the period 1980-2014. Based on the Blundell and Bond two-step system Generalized Methods of Moments technique, the empirical analysis has shown interesting findings. Export product concentration and poverty influence negatively non-resource tax revenue over the full sample, but this effect varies across countries in the sample. Furthermore, the effect of export product diversification on non-resource tax revenue performance depends on the level of poverty. It appears that export product diversification influences positively non-resource tax revenue performance in countries that experience lower poverty rates. From a policy perspective, these findings show that policies in favour of diversifying export product baskets and reducing poverty would contribute to enhancing non-resource tax revenue performance in developing countries.
Structure-Function Relationships of Nuclear Lamins
Authors: Patil Shalaka , Sengupta Kundan
Published: September 2020

Nuclear lamins are type V intermediate filament proteins that form a filamentous meshwork beneath the inner nuclear membrane. Additionally, a sub-population of A-type and B-type lamins is localized in the nuclear interior. The nuclear lamina protects the nucleus from mechanical stress and mediates nucleo-cytoskeletal coupling. Lamins form a scaffold that partially tethers chromatin at the nuclear envelope. The nuclear lamina also stabilizes protein-protein interactions involved in gene regulation and DNA repair. The lamin-based protein sub-complexes are implicated in both nuclear and cytoskeletal organization, the mechanical stability of the nucleus, genome organization, transcriptional regulation, genome stability, and cellular differentiation. Here we review recent research in the field of nuclear lamins and their role in modulating various nuclear processes and their impact on cell function.

Se utilizaron un total de 288 pollitas marrones Isa de ocho semanas de edad dispuestas en un diseño experimental factorial 2 × 4 para evaluar la respuesta al crecimiento, el desarrollo de los órganos, la hematología y la bioquímica sérica de las pollitas en crecimiento administradas con extracto acuoso de Petiveria alliacea. Después de equilibrar el peso, las aves se asignaron a 8 tratamientos que comprendían aves administradas con extracto de raíz acuosa a 4 niveles de concentración (0, 15, 30 y 45 ɡ / litro) y extracto de hoja acuosa a 4 niveles de concentración (0, 15, 30 y 45 ɡ /litro). Cada tratamiento se repitió 3 veces con 12 aves por réplica. El examen fitoquímico mostró que las concentraciones de alcaloides, fenólicos, antioxidantes, taninos, fitatos, esteroides, antraquinonas y oxalatos fueron más altas (P

Background: Comprehensive neuropsychological testing for adolescents living with HIV is rare and often impractical for overstretched healthcare systems in low-resourced settings. This study aimed to 1) test the potential of a simple algorithm to screen for cognitive and functional difficulties among at-risk adolescents, and 2) using this algorithm, investigate the correlates of cognitive and functional difficulties in a large community-traced sample of South African adolescents. Methods: The study interviewed 10-19-year-old adolescents living with HIV (n = 1059) and uninfected community controls (n = 467), attending 53 public health facilities in the Eastern Cape in 2014-15. Cognitive and functional difficulties were assessed using an algorithm (either adolescent reports of memory, attention or concentration problems, or < 60% total recall on a memory task, or caregiver reports of an adolescent being a ‘slow-learner’, or attending a special needs school) and adolescent reports of functional difficulties. Data on healthcare and psychosocial variables were also collected. Multivariable logistic regressions tested correlates of cognitive and functional difficulties, controlling for sociodemographic and household covariates. Results: Across the sample, the prevalence of cognitive and functional difficulties was 19.3% (95% CI: 17.4-21.4). Adolescents living with HIV had significantly higher rates of cognitive and functional difficulties than community controls (21.9% vs. 13.5%, p<.001). Validating the algorithm with self-reported school grade repetition (lifetime) and number of grades repeated, cognitive and functional difficulties were associated with higher odds of lifetime grade repetition (aOR1.62 95%CI 1.24-2.11) and a higher likelihood of repeating multiple grades (β=0.27, p<.001). Independent of covariates, potential correlates of cognitive and functional difficulties among adolescents were higher depressive symptoms (aOR1.18 95%CI1.11-1.26), concurrent infections (aOR1.92 95%CI1.44-2.58), and more often missing school for clinic appointments (aOR1.66 95%CI1.24-2.23). Conclusions: Cognitive and functional difficulties were more prevalent among adolescents living with HIV than community controls and were associated with psychosocial, physical health, and healthcare factors. Simple algorithms – like the one tested in this study – may be feasible for use in low-resourced settings, following validation against neuropsychological assessment batteries in specialised facilities. Routine screening for cognitive and functional difficulties may be integrated into HIV care to identify adolescents for additional support.

BackgroundEthiopian government implemented baby-friendly hospital initiative and community integrated management of childhood illnesses program. Despite early initiation of breastfeeding taken as a key tool for tackling neonatal mortality, EIBF is still low and most of the neonatal mortalities were existed due to delayed initiation of breastfeeding in Ethiopia in general and the practice is not well documented in South West Ethiopia in particular. Therefore, this study aimed to assess early initiation of breastfeeding practice and associated factors among mothers of children aged less than six months of old in Mizan-Aman town, southwest Ethiopia.MethodsA community-based cross-sectional study was employed from April 15 to May 15, 2018. A total of 487 recently delivered mothers were included. The data was collected through face to face interview by using a pre-tested and structured questionnaire. Binary and multivariable logistic regression analysis were employed and p-value < 0.05 was identified as statistically significant factors, and the quality of the data were assured, checked, coded, cleaned and entered in Epi-Info version 3.5.3 and exported to SPSS version 25 for the analysis. ResultThe prevalence of timely initiation of breast feeding was 296(64.50%) in Mizan- Aman Town. Mothers who had < 24 months birth spacing history 1.85(AOR: 95% CI: 1.22, 2.81), mothers’ income level between 1001-1500 Ethiopian Birr 2.21 (AOR: 95% CI: 1.12, 4.37), Primipara mothers 2.00 (AOR: 95% CI: 1.24, 3.23) and home delivery 2.76(AOR: 95% CI: 1.24, 6.14) were important positive predictors for timely initiation of breast feeding. Furthermore, Government employee and merchant mother by occupation was found to be protective factors.Conclusion and recommendationThe practice of early initiation of breast feeding was suboptimal and still below the national average. Intervention at the community and facility level should paid special attention.

Backgrounds: Vascular endothelial cell apoptosis is the first risk factor of atherosclerosis (AS), and it can be induced by high doses of glucose and palmitic acid (PA). The purpose of our study is to use a new generation of high-throughput transcription factors (TFs) detecting method to identify novel candidate key TFs involved in PA-induced vascular endothelial cell apoptosis.Methods: Human umbilical vein endothelial cells (HUVECs) were treated with 0µM PA (control group), 250µM PA (group 1), or 500µM PA (group 2). Candidate TFs among the three groups were determined by significant changes according to t-test, and pathway enrichment, western blot (WB) and RT-qPCR were then performed.Results: Fifty-one TFs showing with significant p value were identified, and 24 TFs with significant p value plus fold change > 2 and with dose-dependence were identified with 12 TFs biologically validated in former studies. Two of the remaining 12 novel TFs, v-maf musculoaponeurotic fibrosarcoma oncogene family protein G (MAFG) and v-maf musculoaponeurotic fibrosarcoma oncogene family protein F (MAFF), were matched to AS known signalling pathways and were validated by WB and RT-qPCR in our study.Conclusions: We identified MAFG and MAFF as novel candidate key TFs in vascular endothelial cell apoptosis, which is the key initial process of AS.
