Authors: Pal Pushkar , Yawongsa Adisorn , Bhatta Rajesh , Shimoda Hiroshi , Rukkwamsuk Theera
Published: October 2021

Background and Aim: Animal rabies is endemic in Nepal, and it occurs in two forms. Although governmental and non-governmental agencies are working toward the control of rabies by mass dog vaccination and stray dog population management, there is still massive number of rabies incidence reported to the reference veterinary laboratory, Nepal. Therefore, this study aimed to assess animal species, temporal, regional, and agro-ecological distribution patterns of animal rabies in Nepal from 2005 to 2017. Materials and Methods: The epidemiological data on animal rabies from the period of 2005 to 2017 were obtained from the Central Veterinary Laboratory, Tripureshwor, Kathmandu, Nepal. The laboratory-confirmed rabies cases were analyzed according to animal species, temporal, regional (developmental zones), and agro-ecological distributions. In addition, descriptive statistics were used to evaluate the distribution patterns of rabies. Results: From 2005 to 2017, a total of 2771 suspected rabies cases in animals were reported to The Central Veterinary Hospital, Kathmandu. Of which, 1302 were found laboratory-confirmed cases. The rabies cases were most commonly reported and confirmed in dogs followed by other domestic animals. The high occurrences were recorded between 2005 and 2007. However, the incidence was increased during 2016 and 2017. The highest number of rabies cases was recorded in the eastern development zone, and the least number in the central zone at regional level. Likewise, it was highest in the Terai (plain) region and lowest in mountainous areas at agro-ecological zones. The findings also revealed that the occurrences of rabies significantly differed among seasons. Conclusion: Rabies is present in Nepal throughout the year and all seasons with seasonal variation. Among the animal species, dogs are the primary animals affected with rabies followed by cattle and other domestic animals. At the regional level, eastern development zone had the highest incidence and Central development zone recorded the least. Similarly, the Terai region had the highest incidence rates, and the least overall prevalence rate was observed in mountainous regions among agro-ecological zones. Therefore, the government should implement the strict enforcement of mass dog vaccination and dog population management through one health approach to control rabies incidence in the country.
"The cultural capital of postmigrants is enormous"
Authors: Stewart Lizzie
Published: October 2021

Lizzie Stewart argues here for a step back from more celebratory discussions of the term 'postmigration' as lens and for critical attention to its role as label. She brings critical perspectives on the 'brand value' of postcolonialism, and on »the rationalizing/racializing logic of capital« (Saha 2018) in the cultural industries, into conversation with a detailed discussion of branding and formatting practices at three theatres in Germany: Ballhaus Naunynstraße; Gorki; Schauspiel Cologne. Entanglements of artist activism with production of culture in a capitalist context provide important lessons and models for the developing usage of the term postmigration in the academic sphere.

Herausforderungen digitaler Lehre
Authors: Gruisbourne Birte de , Matzner Tobias
Published: October 2021

Birte de Gruisbourne und Tobias Matzner untersuchen in diesem Beitrag die sozio-medialen Verschiebungen, die durch digitale Lehre, insbesondere Videokonferenzen als Unterrichtsform, entstehen. Dabei liegt der Fokus auf verschiedenen intersubjektiven Beziehungen im Kontext der Lehre. Um diese medienethisch zu bewerten, wird auf Konzepte aus der Care-Ethik zurückgegriffen. Auch jenseits starker Sorgebegriffe lassen sich damit die gegenseitige Abhängigkeit und Ausgesetztheit in universitären Kontexten fassen und die Neuerun-gen bewerten, die sich durch digitale Lehre unter den Bedingungen einer globalen Pandemie ergeben. Der Text geht auch kurz auf institutionelle und ökonomische Zusammenhänge ein, die aus der hier gewählten Perspektive weniger stark in den Vordergrund rücken.

Published: October 2021

Heyner, Kröpke und Trier widmen sich in diesem Beitrag der Ad-hoc-Umstellung der Tutorienarbeit von Präsenzformaten hin zu digitalen Angeboten. Tutorienarbeit meint im vorliegenden Beitrag sowohl die Planung und Durchführung von Tutorien als auch die Qualifizierungen von Tutorinnen und Tutoren. In den Qualifizierungs- und Zertifizierungsprogrammen an Hochschulen und Universitäten wurde gleichermaßen der Digitalisierungsschub aufgenommen und die Weiterbildung von Tutorinnen und Tutoren in neue digitale Settings überführt. Damit mussten die über die Jahre optimierten Schulungskonzepte, zugeschnitten auf aktivierende Präsenzformate, kurzfristig in die Virtualität verlagert werden. Zusätzlich mussten die Präsenzsettings, sofern sie überhaupt noch durchgeführt werden durften, an die aktuellen (Hygiene-)Vorgaben angepasst werden.

Published: October 2021

This paper explores the challenges and potential of the digitization processes of anthropological collections carried out in Argentina. Firstly, it briefly reviews the historical trajectory and implementation of these processes as an alternative to the access, visibility and use of anthropological collections. Subsequently, a historical overview of these processes in Argentina is presented. Taking as an example the initiatives of digitization of anthropological collections and archives carried out by the Laboratorio de Documentación e Investigaciónen Lingüística y Antropología, the Museo de Antropología and the Instituto de Antropología Córdoba, I examine the epistemological and ontological challenges of the digitization processes.
Resilience Stories
Authors: Mahdiani Hamideh
Published: October 2021

Be resilient! Today, we hear this line in almost any context. The term resilience is among the most repeated buzzwords. But why, simply, do we need to be resilient? Hamideh Mahdiani presents answers to this question by challenging a reductionistic understanding of resilience from single disciplinary perspectives; by questioning the dominance of life sciences in defining an age-old concept; and by problematizing the neglected role of life writing in fostering resilience. In so doing, through a multidisciplinary frame of reference, the book works with various examples from life writing and life sciences, and testifies to the focal role of narrative studies in resilience research.

Does Short-Term International Immersion have a Sustainable Impact on Teachers’ Cultural Competence? Follow-up Interviews Eight Years After a Teaching Experience in South Korea
Authors: Oh Kevin , Nussli Natalie
Published: October 2021

This qualitative study was conducted with teacher candidates studying in a Masters program at a university on the west coast in the United States. The main goal was to capture if immersion in a foreign culture and the short-term teaching of primary and secondary school students in South Korea had any sustainable impact on the participating teachers’ perception of their cultural knowledge, competence, and awareness almost a decade after their immersion experience. The researchers interviewed four teachers who had participated in one of two immersion projects conducted in 2010 and 2011. A questionnaire on teachers’ self-efficacy regarding culturally responsive teaching (modified from Chu & Garcia, 2014) was administered prior to the interview giving the participants a tool to reflect on what it means to be a culturally responsive teacher and to self-assess their own cultural competence and teaching practices. Four themes emerged from the interviews, namely, perspective-taking ability, relationships, teaching strategies, and cultural knowledge. The findings indicate that international immersion not only offers an effective way for pre-service teachers to receive intercultural training. It also has the potential to create transformative learning experiences by immersing students in cultural contexts unfamiliar to them. The findings from this study will be interesting to teacher educators who consider integrating international immersion projects into their teacher education programs.
Optimization design and operating parameters of induction heat-ing system for hardening
Authors: Pavlushin Aleksey V.
Published: October 2021

The paper deals with the problem of optimizing the design and operating parameters of an induction heating system for surface hardening of a steel stepped shaft. The problem of optimal design of an inductor is formulated based on a nonlinear two-dimensional numerical model of coupled electromagnetic and temperature fields, developed in the ANSYS Mechanical APDL software. Alternance method of parametric optimization of systems with distributed parameters is used to optimize induction hardening system. MATLAB software has been used for developing parametric optimization subroutine, which was incorporated into the numerical ANSYS model to simulate a process of induction heating. Commonly used a multi-turn solenoid-style coil fabricated from rectangular copper tubing has been used as a hardening inductor. Besides that, an application of profiled copper turns has been investigated. Optimization of induction hardening system described above allows one to substantially improve heating uniformity and enhance metallurgical characteristics of as-hardened stepped shaft. Localized temperature surplus at an upper diameter shoulder has been minimized. At the same time, sufficient austenitization in the fillet area near stepped region (diameter transition) has been obtained.
Prediction of Potential Fishing Zones for Skipjack Tuna During the Northwest Monsoon Using Remotely Sensed Satellite Data

Published: October 2021

One of economically important fish in the Bay of Bone is Skipjack tuna which their distribution and migration are influenced by surrounding environment.  This study aims to investigate the relationship between skipjack tuna and their environments, and to predict potential fishing zones (PFZs) for the fish in the Bone Bay-Flores Sea using satellite-based oceanography and catch data. Generalized additive models (GAMs) were used to assess the relationship. A generalized linear model(GLM) constructed from GAMs was used for prediction. Monthly mean sea surface temperature (SST) and chlorophyll-a during the northwest monsoon (December-January) together with catch data were used for the year 2012-2013. We used the GAMs to assess the effect of the environment variables on skipjack tuna CPUE (catch per unit effort). The best GLM was selected to predict skipjack tuna abundance.  Results indicated that the highest CPUEs (fish/trip) occurred in areas where SST and chlorophyll-a ranged from 29.5°-31.5°C and 0.15 - 0.25 mg m-3, respectively. The PFZs for skipjack were closely related to the spatial distribution of the optimum oceanographic conditions and these mainly developed in three locations, northern area of Bone Bay in December, in the middle area of the bay (4°-5.5°S and 120.5°-121.5°E) during January and moved to the Flores Sea in February. The movement of skipjack concentration was consistent with the fishery data.  This suggests that the dynamics of the optimum oceanographic signatures provided a good indicator for predicting feeding grounds as hotspot areas for skipjack tuna in Bone Bay-Flores Sea during northwest monsoon. Keywords:  skipjack tuna, potential fishing zones, satellite based-oceanographic data, Northwest monsoon

Innovation Behavior of Salvadoran Food & Beverage Industry Firms
Authors: Peraza Castaneda Elías Humberto , Aleixandre Mendizábal Guillermo
Published: October 2021

This paper presents a quantitative analysis of the external and internal determinants that affect the innovation dynamics of a low-tech sector in a less developed economy; the food & beverage (F&B) industry in El Salvador. The empirical framework relies on a multivariate probit analysis applied to data from El Salvador’s First National Innovation Survey 2013. The results show that R&D activities, use of industrial protection by F&B industry firms as well as relationships between firms and knowledge agents are useful for technological innovations while the qualifications of firms’ workforce and the relationships between firms and value chain agents prove useful for non-technological innovations. In addition, firms can take advantage of their size and location in the department of San Salvador to promote product innovation, whereas firms’ maturity is seen to be a disadvantage. Based on the results to emerge, the role that public science, technology and innovation (STI) policies as well as STI business strategies can play in the Salvadoran agri-food industry innovation system is seen to be huge.

Epitaphios logos – hybrydyczny gatunek retoryki ateńskiej
Authors: Tuszyńska Krystyna
Published: October 2021

Athenian funeral oration (epitaphios logos) belongs to the epideictic rhetoric. But according to Aristotle the topics used in epideictic oratory could be applied in the deliberative kind, after some modification in the matters of language. In this article I consider the means proposed in the narrative part of the composition, which can be used instead of argumentation in epideictic oratory, i.e. amplification, metaphors and actualization (putting things before the eyes, gr. energeia, lat. evidentia). My purpose is to answer the question who was/is the recipient of Athenian funeral oration. In my opinion there are three kinds of primary recipients: the dead soldiers in the battle, the listeners present at the celebration (Athenians and foreigners) and the Idea of Democracy itself. I also try to find the so-called secondary recipient of Athenian funeral oration. I treat Athenian funeral oration as a hybrid genre of Greek rhetoric.
Plethon wobec tradycji teologicznej Greków
Authors: Kujawa Anna
Published: October 2021

Byzantine philosopher Georgios Gemistos Pletho (1355–1452) is regarded as the first Philhellene who rejected Christianity and attempted to restore the pogan religion of Hellenic gods. In his last work Books of Laws (Νόμων συγγραφή) he presents his own system of theology based on ancient philosophy and Greek mythology. The aim of the paper is to outline some main features of Plethon’s theology and to show the influence of Greek tradition on it.
Intramuscular hematoma of the vastus lateralis following percutaneous skeletal muscle microbiopsy: a case report
Authors: Drouin Patrick J. , Islam Hashim , Simpson Craig A. , Gurd Brendon J.
Published: October 2021

Recently, percutaneous microbiopsy needles have been used as a less invasive alternative to the Bergstrom needle for obtaining human skeletal muscle biopsy to assess changes in protein content, gene expression, and enzymatic activities. Unlike the Bergstrom muscle biopsy procedure, potential complications associated with microbiopsies of human skeletal muscle have not been documented. Therefore, the present case report follows a young male's recovery from a muscle biopsy‐induced hemorrhage/hematoma of the right vastus lateralis with the specific aims of (1) informing future participants, researchers, and clinicians on expected time course of recovery and (2) informing methods to minimize future participant adverse event risk during and after the percutaneous microbiopsy procedure. The present case report demonstrates that the inadvertent hemorrhaging of a neighboring vessel by percutaneous microbiopsy procedure can be debilitating. To minimize the risk of muscle biopsy‐induced hemorrhage/hematoma, we advise post‐biopsy compression for up to 15 min and post‐biopsy follow‐up should be completed for up to 72 h. When there is indication of hematoma development, compression should be applied, and the participant should avoid exercise and physical activity.

Published: October 2021

The Romanelli Cave in south-east Italy is an important reference point for the so-called ‘Mediterranean province’ of European Upper Palaeolithic art. Yet, the site has only recently been subject to a systematic investigation of its parietal and portable art. Starting in 2016, a project has recorded the cave's interior, discovering new parietal art. Here, the authors report on a selection of panels, featuring animal figures, geometric motifs and other marks, identifying the use of different types of tools and techniques, along with several activity phases. These panels are discussed with reference to radiocarbon dating of nearby deposits, posing questions about chronology, technology and wider connections between Upper Palaeolithic cave sites across western Eurasia.
Beyond the National Art Schools
Authors: Al Asali M. Wesam , Couret Dania González , Ramage Michael H.
Published: October 2021

The story of the rise and fall of thin-tile vaulting in Cuba after the revolution has always focused on the National Art Schools in Havana, which are typically presented by the scholarly literature as an anomaly in the history of modern Cuban construction. But as M. Wesam Al Asali, Dania González Couret, and Michael H. Ramage show in Beyond the National Art Schools: Thin-Tile Vaulting in Cuba after the Revolution, from 1960 to 1965, the Ministry of Construction (MICONS), led by architect Juan Campos Almanza (1930–2007), built many experimental structures featuring thin-tile vaulting. These designs attest to an innovative architectural program that envisioned the systematic use of thin-tile vaulting at a national scale for houses, schools, recreational structures, and industrial buildings. Drawing on extensive research in the MICONS archives, as well as site visits, interviews, and digital modeling, this investigation provides a nuanced account of the history of architecture in postrevolutionary Cuba. As the authors argue, thin-tile vaulting offered an ingenious and effective solution for a complex range of projects, balancing traditional craft with new technology, allowing for a wide range of different scales, and depending on only local, everyday materials.

Objective

CAV1 encodes caveolin-1, a major protein of plasma membrane microdomains called caveolae, involved in several signaling pathways. Caveolin-1 is also located at the adipocyte lipid droplet. Heterozygous pathogenic variants of CAV1 induce rare heterogeneous disorders including pulmonary arterial hypertension and neonatal progeroid syndrome. Only one patient was previously reported with a CAV1 homozygous pathogenic variant, associated with congenital generalized lipodystrophy (CGL3). We aimed to further delineate genetic transmission, clinical, metabolic, and cellular characteristics of CGL3.

Design/Methods

In a large consanguineous kindred referred for CGL, we performed next-generation sequencing, as well as clinical, imagery, and metabolic investigations. We studied skin fibroblasts from the index case and the previously reported patient with CGL3.

Results

Four patients, aged 8 months to 18 years, carried a new homozygous p.(His79Glnfs*3) CAV1 variant. They all displayed generalized lipodystrophy since infancy, insulin resistance, low HDL-cholesterol, and/or high triglycerides, but no pulmonary hypertension. Two patients also presented at the age of 15 and 18 years with dysphagia due to achalasia, and one patient had retinitis pigmentosa. Heterozygous parents and relatives (n = 9) were asymptomatic, without any metabolic abnormality. Patients’ fibroblasts showed a complete loss of caveolae and no protein expression of caveolin-1 and its caveolin-2 and cavin-1 partners. Patients’ fibroblasts also displayed insulin resistance, increased oxidative stress, and premature senescence.

Conclusions

The CAV1 null variant investigated herein leads to an autosomal recessive congenital lipodystrophy syndrome. Loss of caveolin-1 and/or caveolae induces specific manifestations including achalasia which requires specific management. Overlapping phenotypic traits between the different CAV1-related diseases require further studies.
Análisis de márgenes de exportación
Authors: Matarrita  Lorente Sebastian , Díaz Porras Rafael , Miranda Montes Donald
Published: October 2021

Este artículo evalúa el desempeño exportador de cinco agrocadenas de los países centroamericanos durante el periodo 2000-2016. La evaluación se realiza con la metodología de márgenes de exportación, adaptada al contexto de cadenas de valor en Centroamérica, la cual fija su atención en los vínculos comerciales, tanto en su ampliación como en su profundización. La metodología utilizada es una adaptación de Besedes y Prusa (2012). Los casos analizados son dos cadenas tradicionales de exportación (café y azúcar), dos de orientación tradicional al mercado interno (lácteos y ganadería de carne), así como una cadena con orientación hacia los mercados internacionales (piña). Adicionalmente, se diseñaron tres escenarios que procuran dar luces acerca de en cuáles agrocadenas destacan los países de la región, en qué posición de la cadena surgen las exportaciones con mejor desempeño y qué importancia tiene el comercio intrarregional respecto a las exportaciones con el resto del mundo. Los resultados muestran que en las agrocadenas analizadas, las exportaciones de sus productos primarios fueron las que mejor desempeño tuvieron a lo largo de la cadena. Productos como el azúcar crudo, el café verde y la piña fueron grandes fuentes en la creación de valor y su éxito en los mercados internacionales, lo cual se debió en gran medida a su capacidad para mantenerse en estos. Por otro lado, los productos procesados no se han expandido en tantos mercados como los productos primarios y, por tanto, año con año la entrada a nuevosdestinos pesó más en estos productos.

El objetivo de este artículo es analizar los distintos aspectos que son importantes de regular en las plataformas digitales de transporte remunerado de personas en Costa Rica, con el fin de garantizar un equilibrio entre taxis autorizados, consumidores, las plataformas tecnológicas y los trabajadores de estas plataformas. La investigación es descriptiva con enfoque cualitativo. El principal hallazgo de la investigación es que, a pesar de que desde hace más de un quinquenio se introdujeron las plataformas digitales en el país, los avances en temas de regulación de calidad, precios y condiciones laborales son nulos, y muchos los retos que resolver. Conciliación entre los grupos de presión, modernización de las tarifas actuales del sector de taxis autorizados, regular aspectos de calidad son algunas de las recomendaciones para subsanar la situación actual.
Habitus en torno a la evaluación. (Des)encuentro entre medición y comprensión
Authors: Sánchez-Sánchez Gerardo Ignacio , Jara-Amigo Ximena Elizabeth
Published: October 2021

Objetivo. El objetivo es comprender el habitus que las organizaciones escolares desarrollan en torno a la evaluación educativa. El trabajo se realizó con docentes de educación especial, preescolar, primaria y secundaria. Las propias percepciones y concepciones teóricas y prácticas del profesorado sobre los diversos ámbitos de su quehacer pedagógico están definidas por la institución donde trabaja y las influencias que esta genera. Metodología. La investigación se desarrolló con los parámetros de la metodología cualitativa, de tipo transeccional con un nivel de profundidad exploratoria-descriptiva. Mediante una aproximación de carácter intensivo, se utilizó la entrevista semiestructurada a 40 profesores en programas de postgrado, buscando el significado de las experiencias del personal docente. La información se procesó a través del análisis narrativo. Discusión. Los resultados muestran la presencia de un habitus paradojal en torno a la evaluación, que la configura como cultura de medición, cuantificación y control, lo cual resta oportunidades para transformarla en espacio de debate, reflexión y colaboración. Conclusiones. Se concluye que la evaluación desarrollada en los contextos organizacionales de la escuela se debate entre el (des)encuentro de sus funciones sociales y sus funciones pedagógicas. La proyección de resultados muestra que la evaluación constituye, en los procesos de formación inicial y continua del profesorado, uno de los talones de Aquiles de la práctica educativa. En el ámbito de las intenciones, se perfila la necesidad urgente de convertirla en un proceso que posibilite la función pedagógica, que integre las unidades de enseñanza, aprendizaje y evaluación.
Poverty Dynamics in Turkey: A Multinomial Logit Model
Authors: Çakmak Şahin Senem , Kılıç İbrahim Engin
Published: October 2021

The availability of longitudinal data allows researchers to analyse the dynamics of poverty. By using the Turkish Statistical Institute’s (TurkStat) Income and Living Conditions Survey micro dataset, we analyse the households’ long-term monetary poverty conditions. We categorise poverty as transitory and chronic and employ the multinomial logit method to analyse determinants of each types of poverty. Results indicate that education and household size are the most effective factors for reducing transitory poverty, and for chronic poverty, the most effective factors are having a regular job and having a skilled occupation; insurance, home ownership, and number of children are important determinants for both types of poverty.
Changing Pediatric Hospice and Palliative Care Through Medicaid Partnerships
Authors: Johnson Khaliah A. , Morvant Alexis , James Kristin , Lindley Lisa C.
Published: October 2021

Since its inception in 2010, the Concurrent Care for Children Provision of the Affordable Care Act has enabled seriously ill pediatric patients and their families to access comprehensive, supportive hospice services while simultaneously receiving ongoing treatment-directed therapies. Although this groundbreaking federal legislation has resulted in improvements in care for vulnerable pediatric patients, the implementation of the law has varied from state to state through Medicaid programming. The pediatric professional community is called to consider how Medicaid services can more effectively be delivered by leveraging legislative mandates and collaborative relationships between clinicians, Medicaid administrators, and policy makers. In this article, we examine ways concurrent care has been executed in 3 different states and how key stakeholders in care for children with serious illness advocated to ensure effective implementation of the legislation. The lessons learned in working with state Medicaid programs are applicable to any advocacy issue impacting children and families .

Self-assembly of biopolymer films for UV protection of wood
Authors: Fabijanic Kristina Ivana , Salinas López Aída Ninfa , Pan Long , Cheng Chi-Yuan , Wang Yu , Hao Zhigang , Potanin Andrei , Li Ningwei , Rangel Isaac
Published: October 2021

There is an increasing need for materials with tunable physical and chemical properties that are relatively non-toxic and efficacious for their intended application. Many wood stains and finishes emit toxic chemicals which may have serious implications to one’s health. A novel alternative material is realized between xanthan gum and Neodol, a non-ionic surfactant. The resulting three-dimensional film is evaluated as a free-radical scavenger for the protection of wood at different ratios. Atomic force microscopy visualizes the topography and quantifies the local nanomechanics, while rheological measurements showcase a shift from viscoelastic material to gel. Electron plasmon resonance confirms the free-radical reducing ability (3.5 times), while liquid chromatography mass spectroscopy quantifies the UV degradation of sinapyl alcohol. This material has potential, not only in coating industries as a safer option, but also in those industries requiring flexibility and tenability, namely for biosensors and anti-inflammatory therapeutics.

Investigation of transport behavior in borospherene-based molecular wire for rectification applications
Authors: Vohra Rajan , Kaur Harleen , Kaur Jupinder , Kumar Ravinder
Published: October 2021

The transport properties of molecular wire comprising of B40 fullerene are investigated by employing density functional theory (DFT) and non-equilibrium green’s function (NEGF) methodology. The quantum transport is evaluated by calculating the density of states, transmission spectra at various bias voltages, molecular energy spectra, HOMO-LUMO gap, current–voltage curve, and transmission pathways. In context to its properties, results show that by increasing the length of molecular wire, the device exhibits rectification ratio and prominent NDR behavior. I–V curve scrutinizes that as the length of wire is increased the curve becomes non-linear. This non-linear behavior is more prominent in the case when the length of wire is increased up to six fullerene cages significant rectification ratio (R.R) and negative differential resistance (NDR) comes into the picture. The excellent negative differential resistance ensures that a device with at least six molecular wires can be used as a tunnel diode.

Authors: Georgiyants Marine , Korsunov Volodymyr , Dubrov Sergii , Loskutov Oleg , Bohuslavska Nataliia , Nikonov Vadim , Cherkashyna Lidiya , Oparin Oleksiy , Nartov Pavel , Holianishchev Maksym
Published: October 2021

The aim of the research. The aim of this work was to summarize the scientific literature data on the pathogenesis and intensive care of the severe course of coronavirus infection.
Materials and methods. Databases such as PubMed, Google Scholar, Scopus and Web Of Science 2020-2021 were used for literary searches.
Results. An intense inflammatory response against the SARS-CoV-2 virus in COVID-19 patients causes a cytokine storm and hypercoagulability with the development of acute respiratory distress syndrome (ARDS) and multiple organ failure. Approximately 17 % to 35 % of hospitalized patients with COVID-19 are treated in the intensive care unit, most often due to hypoxemic respiratory failure and the development of ARDS, and between 29 % and 91 % of patients in intensive care units require invasive ventilation.
In addition to acute respiratory failure, hospitalized patients may have acute renal failure (9 %), liver dysfunction (19 %), coagulation disorders (10 %–25 %), and septic shock (6 %).
More than 75 % of hospitalized patients require additional oxygen therapy. Respiratory support could vary from the need for oxygen supplementation through a nasal catheter to invasive ventilation or extracorporeal membrane oxygenation in patients with the most severe ARDS.
The uncontrolled inflammation and coagulation seen in COVID-19 patients is similar to multifactorial ARDS, where a plethora of evidence has demonstrated the ability of long-term corticosteroid therapy (CST) to reduce inflammation-coagulation-fibroproliferation and accelerate recovery.
With regard to the assessment of the benefits of therapeutic anticoagulation in patients with elevated D-dimer, the question has not yet been finally resolved, and research devoted to this is still ongoing.
Conclusions. The approaches to respiratory, anticoagulant, anti-inflammatory therapy in critically ill patients with COVID-19 require further research to determine the optimal treatment tactics

Materials and methods. During the experimental study, the pharmacological methods have been used. The analgesic properties of DEAL were studied in mice on the "Hot plate" model using the Hot / Cold Plate (Bioseb, France) and in the test of the heat immersion in rats.

The results. On the models of pain in the "Hot plate" and tail heat immersion tests, the analgesic effect of the dealcoholized extract of Acorus calamus leaves (DEAL) is determined. On the "Hot plate" model, the use of DEAL probably increased the duration of the latency period. According to the analgesic effect of DEAL and metamizol sodium were comparable to each other continues to 1 and 1.5 hours of experiment, but starting with 2 hours of experiment the analgesic action of metamizol sodium statistically exceeded the analgesic effect of DEAL.

In the test of heat immersion tail in rats, DEAL increased the latency period of shocking of the rats’ tail compared to the starting background by 43.13 % as well as metamizol sodium by 66.6 %. The studies have shown the presence of moderate analgesic effects of DEAL in the investigated dose.

Conclusions. The analgesic effect of a dealcoholized extract of Acorus calamus leaves (DEAL) on a model of pain in the "Hot plate" and heat tail immersion tests has been carried out. Under the "Hot plate" test in mice, DEAL produces a distinct analgesic effect, however, slightly inferior to the severity of metamizol sodium. Presence of moderate analgesic properties of DEAL has been verified in comparison with the metamizel sodium in thetail heat immersion test in rats. The obtained results indicate the influence of DEAL on the central mechanisms of pain formation

Context. Providing the problem of fast calculation of the modular exponentiation requires the development of effective algorithmic methods using the latest information technologies. Fast computations of the modular exponentiation are extremely necessary for efficient computations in theoretical-numerical transforms, for provide high crypto capability of information data and in many other applications.

Objective – the runtime analysis of software functions for computation of modular exponentiation of the developed programs based on parallel organization of computation with using multithreading.

Method. Modular exponentiation is implemented using a 2k-ary sliding window algorithm, where k is chosen according to the size of the exponent. Parallelization of computation consists in using the calculation of the remainders of numbers raised to the power of 2i modulo, and their further parallel multiplications modulo.

Results. Comparison of the runtimes of three variants of functions for computing the modular exponentiation is performed. In the algorithm of parallel organization of computation with using multithreading provide faster computation of modular exponentiation for exponent values larger than 1K binary digits compared to the function of modular exponentiation of the MPIR library. The MPIR library with an integer data type with the number of binary digits from 256 to 2048 bits is used to develop an algorithm for computing the modular exponentiation with using multithreading.

Conclusions. In the work has been considered and analysed the developed software implementation of the computation of modular exponentiation on universal computer systems. One of the ways to implement the speedup of computing modular exponentiation is developing algorithms that can use multithreading technology on multi-cores microprocessors. The multithreading software implementation of modular exponentiation with increasing from 1024 the number of binary digit of exponent shows an improvement of computation time with comparison with the function of modular exponentiation of the MPIR library.
Ahr and CYP1B1 gene expression in type 2 diabetes patients in Vietnam
Authors: Duc Le Hoang , Trung Nam Nguyen
Published: October 2021

Type 2 diabetes is a chronic disease, which has risen dramatically in many countries in the world, including Vietnam. Recently, there is increasing evidence about the link between type 2 diabetes and the exposure to Ahr ligands such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the experimental animal model. In the cell, after activation by the ligands, Ahr moves from the cytoplasm into the nucleus and binds to the nuclear translocator, resulting in transcription of target genes such as Cyp1b1. The development of type 2 diabetes was shown in some people who exposed to TCDD. However, the role of Ahr/Cyp1b1 genes in type 2 diabetes patients has not been elucidated. In this study, the expression of the Ahr and Cyp1b1 genes in blood samples collected from patients with type 2 diabetes and controls was studied for the first time in Vietnam. Analysis of blood glucose showed that this index in the type 2 diabetes patients was higher than that in the control group. Using real-time PCR method, the results showed that the expression of Ahr and Cyp1b1 in type 2 diabetes patients was significantly higher than that in control group. In addition, the expression of Ahr and Cyp1b1 was positively correlated with the blood glucose levels of both groups. These results are initial evidence for the link between activation of Ahr/Cyp1b1 signaling pathway and level of blood glucose so that Ahr/Cyp1b1 genes can be potential targets to treat type 2 diabetes.

Actinomycetes has been extensively studied due to its ability to produce secondary compounds with high application value. Especially their antibiotic ability, more than 40% of antibiotics are derived from actinomycetes of which genus Streptomyces predominates. Moreover, marine actinomycetes have been being of great interest in recent years due to their ability to produce bioactive substances capable of providing diverse and novel chemical structures. In this study, from 8 samples of marine sediments collected in Vung Ang bay in Ha Tinh provinces, we have isolated 20 strains of actinomycetes. The strains were fermented in A1+ medium, the fermentation fluid was extracted 5 times with ethyl acetate, recovered sediment and determined antibacterial and cytotoxic activity. From the screening results, two strains with the highest antibacterial activity and highest cytotoxicity were selected ie., HT03 and HT06. Both strains had antagonistic activity of Enterococcus faecalis ATCC29212 with MICHT03= 32 μg/mL, MICHT06= 16μg/mL, with Stapphylococus aureus ATCC25923 with MICHT03= 64 μg/mL, MICHT06= 32 μg/mL and with Bacillus cereus ATCC 13245 has the same MIC = 16 μg / mL. In addition, the two strains HT03 and HT06 were able to strongly inhibit the yeast Candida albicans ATCC10231 with MICHT03= 16 μg/mL, MICHT06= 8 μg/mL. Especially, two strains, HT03 and HT06, exhibited very good toxicity on all 5 cancer cell lines (MCF-7 breast cancer cell; MDA-MB-231 breast cancer cell; lung cancer cell). NCI-H1975; HeLa cervical cancer cell; AGS gastric cancer cell) at both test concentrations of 30 µg/mL and 100µg/mL. By the analysis of 16S rRNA sequence, the results showed that the HT03 strain had the highest similarity (99.93%) to that of Streptomyces fradiaes and Streptomyces fradiae ATCC. The HT06 strain was defined to belong to Nocardiopsis synnemataformans with the 16S sequence identity of 99.89% to the Japanese standard Nocardiopsis synnemataformans DSM 44143 strain NBRC-102581.

A gene coding for GH5 endoglucanase exploited from metagnomic DNA data of bacteria in Vietnamese goats’ rumen was modularity structure including a catalytic module, a fibronectin-3 like module and an X module. The recombinant enzyme was sucessfully expressed in E. coli and purified.  To study the effect of some metal ions and chemicals on enzyme activity, in this study, we used some tools including Swiss-Prot, ProFunc, COFACTOR for prediction of enzyme structure and ligands interaction. The obtained results indicated that the most similar structure with enzyme had two conserved residues (Asp-190 và Asp-192) linked with Mn2+ within a radius of ~ 3.5 Å from the center of ion Mn2+ and enzyme molecule contained a disulphide bond. Experimental results for essessment of the effect of some metal ions (Ca2 +, Mn2 +, Mg2+, Ni2+, K+, Co2+, Cu2+, Zn2+, Fe3+) at the final concentration of 10 mM and of six common chemicals including SDS (1%), urea (1 µM), 2-mercaptoethanol (1 µM), EDTA (1 µM), tween 80 (1mM), triton X-100 (1 µM) showed that only Mn2+ increased enzyme activity slightly at concentration of 10 mM and two times at the concentration of 40 mM Mn2+. The Mn2+ has been identified as a specific binding agent may increase the stability and activity of endoglucanase GH5.

Wax tree has been cultivated to get lacquer, a valuable source of material that is necessary for many industries and handicrafts. Evaluating not only phenotype but also genotype is essential in order to increase the efficiency of new breeding program. In this study, the genetic relationship at the molecular level of 90 wax trees collected in three regions, i.e., Tam Nong, Thanh Son (Phu Tho) and Chiem Hoa (Tuyen Quang), was analyzed by SSR and ScoT markers. The results revealed a significant diversity among the individuals, with similarity coefficient from 0.41 to 0.98. The sample group collected in Chiem Hoa was significantly different from that in Tam Nong. Most of samples which had a high level of genetic similarity, from 0.95 to 0.98, were pairs of samples at the same geographical origin. The high similarity degree of these samples is likely due to the practice of selecting seeds from high-yield wax tree to be kept for seeds. These results provide the necessary information for new wax tree breeding program.
