Autoimmune encephalitis and epilepsy: evolving definition and clinical spectrum
Authors: Seo Joo Hee , Lee Yun-Jin , Lee Ki Hyeong , Gireesh Elakkat , Skinner Holly , Westerveld Michael
Published: August 2019

Advances in autoimmune encephalitis studies in the past 10 years have led to the identification of new syndromes and biomarkers that have transformed the diagnostic approach to the disorder. The disorder or syndrome has been linked to a wide variety of pathologic processes associated with the neuron-specific autoantibodies targeting intracellular and plasma membrane antigens. However, current criteria for autoimmune encephalitis are quite dependent on antibody testing and responses to immunotherapy, which might delay the diagnosis. This form of encephalitis can involve the multifaceted presentation of seizures and unexpected behavioral changes. The spectrum of neuropsychiatric symptoms in children is less definitive than that in adults, and the incorporation of clinical, immunological, electrophysiological, and neuroradiological results is critical to the diagnostic approach. In this review, we document the clinical and immunologic characteristics of autoimmune encephalitis known to date, with the goal of helping clinicians in differential diagnosis and to provide prompt and effective treatment.
Dea Segetia on Reverse of Coins of Empress Salonina
Authors: Kluczek Agata A.
Published: August 2019

The Ancient Romans knew a deity named Segesta and Segetia. In Gallia there was a cult of dea Segeta. A link between them in the contemporary interpretations became the antonimniani of DEAE SEGETIAE type issues under Valerian and Gallienus for empress Salonina (258–260 AD). According to some researchers, the figure on its reverses is Segesta/Segetia, a deity worshipped in Rome itself. Others suggest that dea Segeta, originates from Gallia. The advocates of both these views notice, however, that the only certain representation of this deity – known by name in the monetary legend – is her image in the coin iconography. Dea Segetia represented on the coins as a syncretic figure which possessed broad competences, all the more so that it received a very comprehensive iconographic form. The article is an overview of various interpretations put on the contents of aurei and antoniniani of DEAE SEGETIAE type, emitted for Salonina Augusta, the wife of the Roman Emperor Gallienus (253–268). Except for this case, the name of Segetia does not appear anywhere else in the imperial coinage while the image of the goddess on these coins combines several features more frequently found in the representations of other deities.

Authors: Grishchenko Liudmyla , Bezugla Tetiana , Zaderko Alexander , Vakaliuk Anna , Mischanchuk Oleksandr , Novychenko Natalia , Cheremenko Anastasiia , Diyuk Vitaliy
Published: August 2019

The functionalization of the carbon fiber based on polyacrylonitrile with sulfur-containing groups of high acidity was carried out in order to obtain the acid-base processes catalysts. Fibers were treated with sulfur vapors in the temperature range of 400-800°C, followed by surface oxidation with 30% hydrogen peroxide solution. Modified samples were investigated by chemical analysis, thermo-programmed desorption with mass spectrometric registration of products, IR spectroscopy and thermogravimetry. It is shown that the obtained materials contain SO3H-functional groups and oxygen-containing groups (carboxyl, lactone, phenolic, etc.) formed in the surface layer during the oxidation of the fiber surface. The chemical analysis showed that the concentration of sulfur in the samples of the modified fiber is 1.6-6.5 mmol/g. The synthesized samples have a satisfactory thermal stability.

The synthesized catalysts were investigated in the model reaction - gas phase dehydration of isopropyl alcohol. It was found that obtained SO3H-containing carbon fibers were catalytically active and had high propylene selectivity. For all the samples obtained there is a complete conversion of alcohol into propylene. The activity of modified carbon fiber samples in the reaction indicated is a fairly high, temperatures of the total conversion of alcohol into propylene are in the range of 160-190°C. During the study of synthesized catalysts in  several cycles of catalysis it have been shown that within repeated use (3 cycles) of all modified fiber samples, the yield of propylene does not decrease, the activity remains stable - the temperature of the dehydration reaction remains unchanged or increases  insignificantly (by 5-10ºС). The temperatures of complete conversion of isopropyl alcohol in propylene for synthesized catalysts are lower than the temperatures of destruction maxima of surface sulfogroups. Thus, modified carbon fibers can be used as low-temperature catalysts of acid-base processes, in particular dehydration of alcohols.
PLASMA-CHEMICAL TECHNOLOGY OF STABILIZATION OF COMPOSITION WATER-COAL FUEL ON THE BASIS OF ORGAN-CONTAINING WASTE WATER
Authors: Makarov А , Klishchenko R , Egurnov A , Kornienko I
Published: August 2019

Industrial and domestic waste water containing waste lubricants, cooling suspensions, waste from the food, alcohol and pulp and paper industries contain fuel residues, solvents, fats, dyes and other organic compounds. Large volumes and multi-component composition of such waste complicate and cost more water purification. Disinfection of such waters using adsorption, membrane or catalytic technologies requires the cost of scarce materials and expensive equipment, as well as leading to the formation of secondary man-made wastes in the form of waste adsorbents, catalysts, membranes, etc.

A promising option is the use of organ-containing sewage in formulations of composite water-coal fuel. At the same time, organic substances of sewage during the combustion of technological equipment allocate additional heat, which allows improving the energy characteristics of the fuel. The possibility of using plasmochemical technology for the stabilization of composite aqueous-coal fuel on the basis of organ-containing wastewater has been investigated. Organic dispersion media used waste after purification of fusel oil and wastewater after the washing of parts for technical purposes. Electrokinetic and rheological properties of composite aqueous-coal fuel have been studied. It has been established that the previous plasmochemical conversion of organo-containing wastewater, which is used as a dispersion medium for composite water-coal fuel, makes it possible to improve its operational properties. The growth of sedimentation stability and the optimization of effective viscosity are achieved both by increasing the electrostatic repulsion of the suspension particles with an increased ξ-potential and by achieving the bimodal composition of the disperse phase.

There is also a significant increase in the absolute values of ξ - the potential reached in the alkaline medium (pH = 10) 55-64 mV for anthracite coal. Accordingly, electrostatic repulsion of coal particles increases and improves in the viscosity in the modified samples is (1.1-1.25 Pa·s) and sedimentation stability (28-36 hours). The sedimentation stability of the fuel obtained is significantly improved in comparison with conventional suspensions of coal in organ-containing wastewater and reaches 28 to 36 hours without the addition of stabilizers. In addition, highly dispersed additives increase the reactivity of the composite aqueous-coal fuel contributes to increasing the caloricity and completeness of the burning of slurry fuel.

Furthermore, the strong connection between millennial and technology affects how they want to be taught in higher education. Various researchers also suggest that oral communication skills can be successfully done by mobile phone capabilities. The data of this study were collected through questionnaires to evaluate the psychological readiness of students. The findings showed that the students have positive attitude toward MALL. All the students have smartphone to support the educational purposes inside and outside classroom. Nevertheless, lecturers need to be aware of the background and technological skills of the learners before embedding MALL into speaking class. Keywords: mobile assisted language learning, readiness, speaking, higher education
Error Analysis on English Translation from Indonesian on Public Facilities in Semarang City
Authors: Savitri Ayu Ida
Published: August 2019

Delivering exactly and accurately the same message of a text under minor bias and without any form and meaning shifts in another language has always becoming the final-purpose of a translation process as the main objective of translation is transferring the message of a text in one language into another one by highly considering on how the readers of another language will understand and enjoy the translation while obtaining the needed information. Most of the time, the difficulties of expressing similar message in another language lays on the different interpretation due to the different culture. To deal with it, a translator must be a ‘balance-bilingualist’ as she/he must understand well the languages involved in the translation process. Sometimes, the error in translation occurs when the structure of the first language/the source language (SL) of the translator influence the translation in second language/ target language (TL). To analyse the error, Error Analysis Theory from Richard (1974) and Types of Error in producing English from Dulay (1982) is used as it is aimed at revealing the kinds or error along with the factors influencing the error. This research is done to describe the error in public translation such as billboard, banner and decoration containing wise words around Semarang City to show the kinds of error and the factors influencing those errors along with the way the translator translate the text under Translation Theory from Catford (1965) and Nida and Taber (1969) also Translation Model from Venuti (2000) and Translation Method and Technique/ Procedure from Vinay and Darbelnet (1958). The result shows that most of the errors are in generalization that happened as a result of the influence of the first language/SL structure and writing system that is different with that of the second language/TL.

Published: August 2019

Objective: Large number of comprehensive studies has been carried out on levosimendan. There are many studies on its use, especially in cardiac dysfunction, ischemic cardiac surgery, and heart transplantation surgery. But, there are limited number of studies regarding its use in mitral valve interventions and ischemic mitral dysfunction combined with coronary artery by-pass surgery (CABG). We aimed to investigate the efficacy of levosimendan usage on patients undergone combined coronary artery by-pass grafting and mitral valve surgery because of ischemic mitral dysfunction.Methods: Subsequent patients, who have undergone concurrent CABG and mitral valve repair surgery by a single surgery team, were retrospectively examined. 36 patients were divided into 2 groups; Group 1 (levosimendan therapy group, n=15) and Group 2 (n=21).Results: There was no statistically significant difference between the groups in terms of preoperative characteristics, echocardiographic data of the patients and preoperative medication. Inotrope therapy was required for 12 patients in Group 1, which was statistically higher than Group 2 (n=5, p=0.001). Moreover, IABP following LCOS utilized six and two patients in group 1 and 2 with a statistically significant difference (p=0.03), espectively.Conclusion: We recommend using levosimendan on selected patients for its several beneficial effects. However, we do not satisfied with the treatment because the pathology of all patients was not related to ischemia, more to the alteration of ventricle anatomy with deterioration of diameters.
Mechanical Response Changes in Porcine Tricuspid Valve Anterior Leaflet Under Osmotic-Induced Swelling
Authors: Salinas Samuel D. , Clark Margaret M. , Amini Rouzbeh
Published: August 2019

Since many soft tissues function in an isotonic in-vivo environment, it is expected that physiological osmolarity will be maintained when conducting experiments on these tissues ex-vivo. In this study, we aimed to examine how not adhering to such a practice may alter the mechanical response of the tricuspid valve (TV) anterior leaflet. Tissue specimens were immersed in deionized (DI) water prior to quantification of the stress–strain responses using an in-plane biaxial mechanical testing device. Following a two-hour immersion in DI water, the tissue thickness increased an average of 107.3% in the DI water group compared to only 6.8% in the control group, in which the tissue samples were submerged in an isotonic phosphate buffered saline solution for the same period of time. Tissue strains evaluated at 85 kPa revealed a significant reduction in the radial direction, from 34.8% to 20%, following immersion in DI water. However, no significant change was observed in the control group. Our study demonstrated the impact of a hypo-osmotic environment on the mechanical response of TV anterior leaflet. The imbalance in ions leads to water absorption in the valvular tissue that can alter its mechanical response. As such, in ex-vivo experiments for which the native mechanical response of the valves is important, using an isotonic buffer solution is essential.

Published: August 2019

Human β2-microglobulin (b2m) protein is classically associated with dialysis-related amyloidosis (DRA). Recently, the single point mutant D76N was identified as the causative agent of a hereditary systemic amyloidosis affecting visceral organs. To get insight into the early stage of the β2m aggregation mechanism, we used molecular simulations to perform an in depth comparative analysis of the dimerization phase of the D76N mutant and the ΔN6 variant, a cleaved form lacking the first six N-terminal residues, which is a major component of ex vivo amyloid plaques from DRA patients. We also provide first glimpses into the tetramerization phase of D76N at physiological pH. Results from extensive protein–protein docking simulations predict an essential role of the C- and N-terminal regions (both variants), as well as of the BC-loop (ΔN6 variant), DE-loop (both variants) and EF-loop (D76N mutant) in dimerization. The terminal regions are more relevant under acidic conditions while the BC-, DE- and EF-loops gain importance at physiological pH. Our results recapitulate experimental evidence according to which Tyr10 (A-strand), Phe30 and His31 (BC-loop), Trp60 and Phe62 (DE-loop) and Arg97 (C-terminus) act as dimerization hot-spots, and further predict the occurrence of novel residues with the ability to nucleate dimerization, namely Lys-75 (EF-loop) and Trp-95 (C-terminus). We propose that D76N tetramerization is mainly driven by the self-association of dimers via the N-terminus and DE-loop, and identify Arg3 (N-terminus), Tyr10, Phe56 (D-strand) and Trp60 as potential tetramerization hot-spots.

Published: August 2019

Food safety is one of the main concerns in the world and in wine it depends mostly on metabolites of microbial origin. The aim of this study was to investigate the occurrence of natural contaminants, ochratoxin A and biogenic amines (cadaverine, histamine, putrescine and tyramine), in Croatian commercial red wines originating from different Croatian wine-making regions. Ochratoxin A was detected in 92.8% of samples, however its concentrations in all samples were more than 10-fold lower than the limit set by the European Union (2 µg/kg), marking these wines as safe for consumption. The frequency of occurrence and measured concentrations of ochratoxin A were higher in wines produced in southern regions with highest values obtained in wines from southern Dalmatian islands. All samples were contaminated with cadaverine and putrescine, while 88.2% and 82.7% were contaminated with histamine and tyramine, respectively. Histamine concentrations ranged from below the limit of detection to 8.5 mg/L. Higher histamine concentrations were measured in wines with higher pH values which coincided with southern geographic origin. These results reinforce the need for routine detection and quantification of biogenic amines in Croatian wines to achieve better control of vinification and minimize their formation.
Multifaceted Geometric Assessment towards Simplified Urban Surfaces Built by 3D Reconstruction
Authors: Liu Sheng’en , Yi Hui , Chen Xiangning , Wang Decheng , Jin Wei
Published: August 2019

Large-scale three-dimensional (3D) reconstruction from multi-view images is used to generate 3D mesh surfaces, which are usually built for urban areas and are widely applied in many research hotspots, such as smart cities. Their simplification is a significant step for 3D roaming, pattern recognition, and other research fields. The simplification quality has been assessed in several studies. On the one hand, almost all studies on surface simplification have measured simplification errors using the surface comparison tool Metro, which does not preserve sufficient detail. On the other hand, the reconstruction precision of urban surfaces varies as a result of homogeneity or heterogeneity. Therefore, it is difficult to assess simplification quality without surface classification. These difficulties are addressed in this study by first classifying urban surfaces into planar surfaces, detailed surfaces, and urban frameworks according to the simplification errors of different types of surfaces and then measuring these errors after sampling. A series of assessment indexes are also provided to contribute to the advancement of simplification algorithms.
Targeting the nsp2 Cysteine Protease of Chikungunya Virus Using FDA Approved Library and Selected Cysteine Protease Inhibitors
Authors: Kumar Prateek , Kumar Deepak , Giri Rajanish
Published: August 2019

Chikungunya virus (CHIKV) infection is one of the major public health concerns, leading thousands of cases every year in rural as well as urban regions of several countries worldwide, few to mention are India, Philippines, Indonesia, and also in American countries. The structural and non-structural proteins of CHIKV are structurally and functionally similar to other alphaviruses such as Sindbis virus, Venezuelan Equine Encephalitis virus. The precursor protein of non-structural proteins is cleaved by proteolytic activity of non-structural protein (nsp2). This multifunctional nsp2 carry out nucleoside-triphosphatase (NTPase) and RNA helicase activity at its N-terminal and protease activity at C-terminal that makes it primarily a drug target to inhibit CHIKV replication. Until the current date, no suitable treatment for chikungunya infection is available. The introduction of a new drug into the market is a lengthy process, therefore, drug repurposing is now familiar approach that cut off the time and cost of drug discovery. In this study, we have implemented this approach with Food and Drug Administration (FDA) approved drugs and known cysteine protease inhibitors against CHIKV nsp2 protease using structure-based drug discovery. Our extensive docking and molecular dynamics simulations studies leads to two best interacting compounds, Ribostamycin sulfate and E-64, with utmost stable complexes at active site of nsp2 protease. Therefore, these compounds could be suitable for inhibiting CHIKV protease activity, and ultimately the viral replication.

Published: August 2019

El artículo tiene como propósito, construir los elementos teóricos necesarios, que sustente lo constitutivo de la Gerencia Social Universitaria en Venezuela, desde la configuración de la UNEFA, la UNESR y la UBV. Con respecto a la metodología está enmarcada en el paradigma cualitativo, su enfoque es el interaccionismo simbólico. Los actores sociales son los docentes, empleados y estudiantes de las tres universidades tomadas como unidades de estudios y los cuales fungieron como informantes claves. La técnica de recolección de información fue la observación participante y la entrevista a profundidad. Para el análisis e interpretación de la información se utilizó la matriz GLATER, la cual sus autoras González y Hernández (2000) lo definen “como una matriz y un instrumento para evaluar las categorías provenientes de su investigación o de otros autores” (p.20). Para establecer la confiabilidad y valides se aplicó la triangulación. En la investigación sobresale la siguiente reflexión; el individuo que se desempeñe como gerente universitario le corresponderá tomar como marco de referencia los postulados de la gerencia social, toda vez que la misma es una gerencia compartida, solidaria, transparente, ajena a intereses sectoriales o corporativos; es una gerencia  sensible e inteligente orientada al bien común, que desarrolla habilidades para la concertación, los consensos y los acuerdos.
Multi Objective Geometric Programming with Interval Coefficients: A Parametric Approach
Authors: Mousavi Zeinab , Saraj Mansour
Published: August 2019

When we talk of optimization in industry we need to pay attention in searching for very powerful and flexible optimization techniques. One of such techniques which has attracted the interest of many researchers in the last few decades is called geometric programming that provides a powerful tool for solving nonlinear problems. As we know in the real world, many applications of geometric programming are engineering design problems. Generally, engineering design problems deal with multi-objective functions, in which their objectives are often in conflicts with each other. This paper considers a solution method when the cost, the constraint coefficients, and the right-hand sides in the multi-objective geometric programming problems are imprecise and represented as interval values. This problem is reduced with the method of weighted sum to a single objective function and further by applying interval-valued function, we solve the problem by geometric programming technique. The ability of calculating the bounds of the objective value developed in this paper might help lead to more realistic modeling efforts in engineering optimization areas. Finally a numerical example is given to illustrate the methodology of solution and efficiency of the present approach.

The rT - X family of distributions induced by V which have been introduced in [1] is further explored in this paper. In particular, we have obtained some basic mathematical properties of this new family. The simulation study shows the method of maximum likelihood is adequate in estimating the unknown parameters in sub-models of this new class of statistical distributions. Further, the application shows that sub-models of this new family of distributions are useful in material science engineering and related disciplines that call for modeling and forecasting of related data sets. Finally, inspired by the Ampadu-G family of distributions [2], we propose a new class of distributions that have never appeared in the literature, and ask the reader to investigate some properties and applications of this new class of distributions.
