MARADONA… E O MUNDO PENSOU O SUPER-HOMEM
Authors: Cunha António Camilo Teles Nascimento
Published: July 2021

O ensaio faz o elogio a Diego Armando Maradona. Um atleta (futebolista) que encimou o humano nas suas mais diversas dimensões. Por um lado, a imanência na sua complexidade individual, psicológica, social e axiológica (o bem, o bom, o belo e o seus contrários); por outro, a transcendência da (na) imanência na medida em que eleva facetas e virtudes que o homem comum não consegue mas gostaria de atingir. Maradona acabou por projetar toda a dimensão mítica e lendária dos arquétipos dos heróis Gregos e Romanos, onde excelência e fragilidade (sua superação) convivem, numa (re) interpretação incessante.

Published: July 2021

O objetivo do estudo foi avaliar a contribuição relativa de membros inferiores no nado crawl utilizando o método de perturbação da velocidade (VPM) em atletas de diferentes níveis de habilidade.  Participaram do estudo 106 nadadores, os quais foram divididos igualmente em dois grupos de acordo com o nível de habilidade (competitivo e recreativo). Os nadadores realizaram 8 tiros máximos de 15 metros nadando crawl em 4 diferentes condições com o mínimo de 2'30" de intervalo entre os tiros (nado completo; completo com paraquedas; apenas pernada e; pernada com paraquedas). Todos os tiros foram filmados com uma câmera subaquática (GoPro Hero4 Black), e os parâmetros de interesse registrados foram: velocidade média do nadador; o arrasto ativo e potência de nado em cada uma das condições. Para comparação estatística da contribuição relativa de membros inferiores entre os grupos foi realizado um teste T. O nível de significância adotado foi de p<0.05.  O resultado principal mostrou na comparação entre grupos que a contribuição relativa de membros inferiores, foram significativamente maiores para o grupo recreativo, 33,9 ± 23,1 % vs.  22,5 ± 10,3 % (p=0.02). Por fim, o VPM se mostrou uma técnica de fácil execução capaz de avaliar a contribuição relativa de membros inferiores no nado crawl, tornando esta informação acessível para treinadores.

Authors: Mezêncio Bruno , Ferreira Jacielle Carolina , Amadio Alberto Carlos
Published: July 2021

A Biomecânica é uma ciência do grupo das ciências biológicas que trata de análises físico-matemáticas de sistemas biológicos e, como consequência, de movimentos humanos. Estes movimentos são analisados através de leis e normas mecânicas com relação a parâmetros específicos do sistema biológico. Atualmente a Biomecânica constitui-se numa disciplina curricular presente na quase totalidade dos cursos universitários de formação de bacharéis e licenciados em Educação física e Esporte, Fisioterapia, entre outros cursos. Sua consolidação foi acompanhada por uma grande evolução nas técnicas e recursos metodológicos aplicados, e ainda permanece em amplo desenvolvimento. Pretende-se com este artigo, apresentar um breve histórico da biomecânica como área de investigação, descrever seus principais métodos de investigação, sumarizar as principais particularidades da biomecânica no meio liquido e apresentar as atuais tendências e perspectivas futuras para a investigação do movimento humano.

A corrida é uma prática largamente utilizada por aqueles que almejam manter ou aprimorar a aptidão física. O treinamento de força tem sido recomendado como forma de aumentar o desempenho e reduzir o risco de lesão em praticantes de corrida, no entanto, a relação entre força muscular e mecânica da corrida ainda necessita de melhor compreensão. O objetivo do presente estudo foi comparar a biomecânica da corrida entre indivíduos praticantes de musculação, com diferentes níveis de força absoluta no agachamento. Inicialmente participaram do estudo 24 voluntários. Baseado na força absoluta em 10RM no agachamento, os voluntários foram divididos em tercis: grupo de força superior (GFS), grupo de força inferior (GFI) e grupo de força mediana. Para comparação da mecânica da corrida foram analisados o GFS e GFI. Foram coletados parâmetros dinâmicos e cinemáticos durante corrida em esteira. Não se observou diferenças entre os grupos para nenhuma das variáveis investigadas.

CHARACTERIZATION OF TEXTILE ELECTRODES FOR EMG MEASUREMENTS
Authors: Fonseca Pedro Felipe Pereira da , Borgonovo-Santos Márcio , Catarino André , Correia Miguel Velhote , Vilas-Boas João Paulo
Published: July 2021

Textile electrodes are an alternative to conventional silver-chloride electrodes in wearable systems. Their easy integration in garments and comfort provided to the user make them an interesting development of textile engineering. The potential of such electrodes to allow more unobtrusive data collection in health and sports context may enable the development of biosensing garments to be used in biomechanics. However, proper validation of the recorded signals is paramount, and few studies have yet presented consistent methodologies for textile-based electromyographic recordings. This study presents the validation of the electrical and morphological properties of electromyographic signals recorded with textile electrode, in comparison to conventional silver-chloride electrodes. Results indicate that both sets of electrodes have identical signal-to-noise ratios, but with distinct impedance frequency responses. Electromyographic envelope morphologies are also identical, although textile electrodes usually have lower amplitudes.

Authors: Borges Eduardo , Gianolla Fábio , Serrão Júlio
Published: July 2021

No melhor de nosso conhecimento, nenhum estudo da literatura comparou a ativação eletromiográfica bilateral dos músculos multífidos e longuíssimo dorsal entre o agachamento e elevação pélvica. O objetivo do presente estudo foi comparar a ativação eletromiográfica por mensuração bilateral dos músculos multífidos e longuíssimo dorsal entre os exercícios de agachamento livre e elevação pélvica em 9 voluntários, competidores universitários de fisiculturismo que estavam utilizando ambos os exercícios na rotina de treinamento. Os resultados mostraram que ambos os músculos apresentaram maior atividade eletromiográfica na fase ascendente. Com relação ao efeito do exercício, os multífidos apresentaram maior ativação na elevação pélvica (80,9±21,4 x 58,5±17,7 para o pico, p<0,05 e 50,1±17,6 x 34,5±12,1 para a média, p<0,05). Não houve diferença entre os exercícios para o longuíssimo. Concluímos que os músculos multífidos são mais solicitados no exercício de elevação pélvica e ambos os exercícios apresentam maior ativação na fase ascendente.

Davos, Nueva York y Porto Alegre
Authors: Ibisate F. Javier
Published: July 2021

Si en las treinta y una reuniones de Davos se reunieron quienes tienen una visión económica y financiera y quienes, al mismo tiempo, manejan las riendas del orden mundial, el Foro Social de Porto Alegre busca dos objetivos: presentar la globalización desde los sectores más inmersos en la sociedad civil y su participación activa en la reformulación de un nuevo orden mundial. En respuesta a los problemas debatidos en cumbres mundiales anteriores y a la agenda de Davos 2001, los asistentes de Porto Alegre se centraron en algunos grandes temas: la distribución de la riqueza, el problema de la deuda externa, la especulación financiera, la revisión del FMI, del BM, de la Organización Mundial del Comercio, de la participación de la sociedad civil y la democracia, del deterioro del medio ambiente, etc. Y aunque lo expuesto en este artículo no agota todo el programa ni toca el mensaje principal de Porto Alegre, sí sintetiza tres de los grandes problemas que nos muestran las contradicciones de una globalización que, hoy por hoy, se halla en grave recesión y desconcierto. Por tanto, si en Davos -Nueva York los participantes salieron con más inquietudes que soluciones, el programa de Porto Alegre sí nos da más esperanza, porque el programa es mucho más amplio y presenta otra alternativa de solución.

Un camino insurgente a la democracia. La movilización popular, los intereses económicos y las transiciones de los regímenes en El Salvador y Sudáfrica
Authors: Wood Elisabeth Jean
Published: July 2021

En El Salvador y Sudáfrica, la movilización de los marginados a nivel económico y social impulsó la transición hacia la democracia, lo cual produjo la liberalización inicial del régimen y sentó, finalmente, las bases políticas y económicas para un acuerdo de democratización. Estos casos nos brindan la oportunidad para analizar el mecanismo mediante el cual la movilización "desde abajo" impulsa algunas transiciones de régimen. En este camino insurgente a la democracia, una movilización sostenida de personas pobres y de clase obrera transformó intereses claves de las elites económicas, presionando de tal manera al Estado, que éste tuvo que establecer acuerdos con los insurgentes, fortaleciendo así a los moderados del régimen contra los de línea dura. De esta manera tuvieron lugar las transiciones negociadas hacia la democracia. Los personajes centrales de estas transiciones no eran los grupos de la elite en competición entre ellos mismos, tal como ha sido el caso de la mayoría de las transiciones en América Latina y el sur de Europa, sino representantes de distintas clases, cuyos conflictos de interés económico impulsaron el conflicto armado y cuya interdependencia económica contribuyó a su resolución, a favor de la democratización.

Los acuerdos de paz diez años después. Una mirada desde los ciudadanos
Authors: Cruz José Miguel
Published: July 2021

Los salvadoreños encuentran el décimo aniversario de la firma de los acuerdos de paz sumidos en un clima de desencanto político. El autor intenta un análisis desde la opinión pública para comprender ese desencanto desde las expectativas generadas por el tratado de paz. Se concluye que muchos salvadoreños no encontraron cambios sustanciales en la resolución de los problemas fundamentales del país, algunos de los cuales se agravaron, y ello ha llevado a que los ciudadanos se sientan ahora más decepcionados de la situación y del rumbo del país, creando las condiciones para una crisis del sistema político vigente.

Published: July 2021

En este artículo se analiza la situación actual de los derechos humanos, pero no comparándola con el estado de barbarie que se llegó a alcanzar entre 1972 y 1992, sino confrontándola con las aspiraciones de humanismo y humanidad que deben guiar la edificación de un El Salvador distinto. En este sentido, es preciso analizar los avances que se han tenido en el transcurso de estos diez años y plantear los desafíos del presente de cara al futuro. El objetivo es verificar su cumplimiento, en términos de justicia integral para todas las personas y no el funcionamiento de un sistema al servicio de determinados grupos de poder.

Development and assessment of a membrane bioreactor for wastewater treatment
Authors:   , Osifo Peter Ogbemudia
Published: July 2021

A woven fibre membrane unit was developed locally and used for this study. The membrane unit was submerged in the aerobic tank of an anoxic-aerobic biological treatment process to treat dairy effluent. Another unit similar to the process above was also set up but with a gravity settling tank replacing the membrane unit. Kinetic studies were done on both processes and their results compared. Effluent characteristics of both processes were also compared. For the membrane bioreactor, the effectiveness of two backflush methods ie air and water, were tested. In this study it was discovered that air backflush could remove the clogging formed at external and internal pores of the membrane better than water backflush measured in terms of rate of pressure recovery and energy consumption. The effluent quality of the membrane bioreactor (MBR) in terms of COD, nitrogen, suspended solids and turbidity was excellent under all conditions tested and was better than conventional activated sludge system. The COD removed based on the average value in MBR was 96.02 % compared to 94 % conventional system. A mass balance of the processes showed that 79 % in the form of nitrogen fed into both the MBR and conventional systems was denitrified. The effluent suspended solids from the MBR was not determinable while that of conventional system was 2.09 mglL. Maximum specific nitrification rate determined graphically was 3.0 d-I and 2.10 d-I in conventional and MBR respectively. The smaller value of nitrification rate in MBR could be attributed to large number of nitrifier volatile suspended solids in the system. The estimated true yield and decay rate coefficients of conventional system is 0.204 kgVSS/kgCOD and 0.013 d-I respectively. The flux obtained from this study is between 22 and 92 L/m2.h. However, the average flux value is 57 L/m2.h for the whole period of operation. Regular flux decline observed during operation was improved through regular backwash with air and chemical cleaning. The transmembrane pressure did not as whole increase more than 55 kPa due to frequent cleaning of the membrane surface.
Cloning and expression of xylanase variants in Pichia pastoris
Authors:   , Govindarajulu Natasha
Published: July 2021

Microbial xylanases have attracted considerable research interest because of their various applications in biotechnology including the biobleaching of kraft pulp, to increase the nutritional value of foods and animal feed as well as for their potential use in the production of ethanol and methane. In the paper and pulp industry, the bleaching process involves the use of toxic chemicals and in the interim produces harmful gases that have a negative impact on the environment. The application of enzymes for this process will potentially reduce the environmental pollution by this industry. In addition, using an enzyme that is thermostable and alkali tolerant means that they will remain active under the required processing conditions. The xylanase gene, xynA derived from Thermomyces lanuginosus DSM 5826, was previously evolved to produce a number of xylanase variants, which were further enhanced for increased thermostability and alkalinity. In this study, these variants were cloned in Pichia pastoris using the pBGP1 vector to achieve extracellular production of the recombinant proteins. The xylanase genes were isolated using PCR. Both vector and DNA inserts were linearized with restriction enzymes EcoRI and XbaI and ligated. Electroporation was employed to transform the yeast with the recombinant plasmids. This was followed by the expression of the enzymes in P. pastoris grown in yeast peptone glucose (YPD) medium. Enzyme activity was thereafter assessed and the yeast was found to produce 164, 78, 96 and 142 IU/ml of S325, S340, G41 and G53 xylanase respectively, higher levels than bacterial hosts. The enzymes were then characterized and it was established that the optimum temperatures and pH for maximum xylanase activity were, 60°C, pH 6 for S325; 40°C, pH 5 for S340; 60°C, pH 6 for G41 and 60°C, pH 7 for G53. i The pH and temperature stabilities of the respective enzymes were investigated, the S325 variant was exceptionally stable at a pH between 5 and 7 and temperature range of 40-80°C and retained a minimum of 40% of activity at higher pH and temperature after an incubation period of 90 min. The S340 variant was the least thermostable and alkali stable from all four variants, it however retained 40% of activity when subjected to conditions of pH 9, 80°C after 90 min. The G41 and G53 were highly stable under the pH and temperature conditions that they were subjected to. Thus being suitable for potential application in the pulp and paper industry. The enzymes were able to retain 80% of activity at pH 9, 80°C after 120 min. P. pastoris has been proven to be a more suitable protein expression vector than E. coli for a number of reasons, including; the ability to perform complex post-translational modifications and grow to high densities in minimal media resulting in the production of a high yield of heterologous proteins.
Fabrication of graphene based aptasensors for early detection of prostate cancer by experimental and computational techniques
Authors:   , Putri Athika Darumas
Published: July 2021

High prevalence and mortality cases of prostate cancer (PCa) have increased around the world, particularly in developing countries. Several forthcoming factors have been revealed nowadays, one of them is due to the incapability of the diagnostic methods to produce reliable results, which impacts negatively on cancer-treatment. However, a sensitive diagnosis of PCa cells remains a challenge in the field of biosensors. Emerging whole-cell detection as biosensing targets has opened up avenues for successful cancer diagnostics, due to high selectivity among other cells. A switchable and flexible surface-based graphene material is one of the techniques that revolutionized smart biodevice platforms in biosensor technology. In this present study, a covalently linked poly-(N-isopropylacrylamide) (PNIPAM) to graphene oxide surface has been employed as “on/off”-switchable aptamer-based sensor for the detection of PC3 whole-cancer cell. The constructed surface has benefitted from PNIPAM, as the thermal-stimulus agent, which allows the coil-to-globule transitions by triggering temperature changes. When the system is above its lower critical solution temperature (LCST) of 32oC, PNIPAM will exist as hydrophobic -globular state providing an “on” binding region for the whole-cell, reaching the interactions on the biosurface. The “off” binding systems is only possibly when the PNIPAM turns into extended-state by lowering its temperature below LCST. The first principle studies have successfully characterized the electronic behavior with particular emphasis of PNIPAM monomer functions along with the description of the structural energetics of complex through density functional theory (DFT). Docking studies have further been performed to predict a plausible binding aptamer toward the protein-representative PCa cell. To better understand the prospect of an aptamer-based tunable biosensor, molecular dynamics (MD) highlighted the behavior of PNIPAM-grafted GO in exhibiting a globular and extended conformations at above and below LCST, permitting the biomolecules to interact with each other as well as to avoid interactions, respectively. Experimental studies have been included to validate the theoretical predictions by fabricating real-biosensor systems using electrochemical impedance technique, resulting a low-detection limit down to 14 cells/mL. Engagement between theoretical and experimental studies delivered an enhanced tunable-biosensor performance for the detection of whole cell prostate cancer.
An investigation of the voltammetric behaviour of antioxidants in flavonoids
Authors:   , Ramsarup Lee-Ann
Published: July 2021

The two case studies in this work involve the development and fabrication of an electrochemical biosensor using various enzymes for the evaluation of the electrochemical responses, relating to the total phenolic (TP) content and the antioxidant activities in wine and tea samples respectively. The modification of the glassy carbon electrode (GCE) was carried out using green apple as an enzymatic source of polyphenol oxidase and laccase enzyme. The experimental variables were optimized using the Box-Behnken experimental design as a predictive model, for a better understanding of the parameters and their interaction responses with each other during an electrochemical analysis. This multivariate optimization method is based on a factorial design, where the three most influential factors include the electrolyte pH, the deposition time (td) and the scan rate (sr). The design was run in a single block fashion while random order of experiment was selected to provide greater protection against the effects of outlying variables. The optimized results obtained yielded the most suitable conditions for the determination of the TP content in wine samples. They were selected as follows: phosphate buffer of pH 7.65 as supporting electrolyte, td 29.8 s and sr 25.0 mV/s respectively. The method was optimized for the current signal at a deposition potential of 0.2 V and within an oxidation potential of -0.2 V to 0.6 V. Good analytical responses were obtained with apple sensors for the detection of TP content in wine samples, with a higher concentration in red wines than in white wines. Differential pulse voltammetry (DPV) and cyclic voltammetry (CV) were used to establish and interpret the redox mechanisms of flavonoids present in alcoholic and non-alcoholic beverages. The sensor responses were evaluated by first, investigating the changes in the total phenolic (TP) content in wine samples using catechin as a standard. Thereafter, the electrochemical behaviour of rutin and ascorbic acid, antioxidant capacities (trolox reagents) were established in tea samples, yielding a positive linear correlation between the trolox equivalent antioxidant capacities (TEAC) and TP content (R2 = 0.9812 ± 0.012). DPV was applied to the laccase modified GCE, and the experimental results indicate that this sensor shows good reducing properties. The scavenging ability of 2,2’-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) a diammonium salt, was assessed in the sample extracts, which yielded half-maximal effective concentration (EC50) values of 10.80 μg/ml and 11.62 μg/ml for ascorbic acid and rutin respectively. These findings indicated that the experimental design was a convenient method to evaluate the statistical significance of the optimised parameters, and the positive linearity for the TEAC and the TP content confirms the robustness of this methodology.
EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON NUTRIENT USE EFFICIENCY OF MAJOR NUTRIENTS: A REVIEW
Authors: . Barkha , Chakraborty Ananya
Published: July 2021

Nutrient use efficiency (NUE) is an important concept in the evaluation of crop production systems. With emerging nutrient deficiencies under intensive agriculture, there is a need to improve NUE. One of the approaches to enhance it is by judicious use of fertilizers (adequate rate, effective source, methods and time of application) as well as inclusion of organic manures. Organic nutrient sources are very effective but as their availability is not sufficient to meet the nutrient demand, we have to integrate both organic and inorganic sources of nutrients together in order to achieve higher NUE. Common measures of NUE include Partial Factor Productivity (PFP), Agronomic Efficiency (AE), Apparent Recovery Efficiency (RE), Physiological Efficiency (PE) and Internal Utilization Efficiency (IE). Mineral Fertilizer Equivalent (MFE) is another parameter that can be used to assess short term release of nutrients (mainly nitrogen) from organic nutrient sources

Though organizational citizenship behavior (OCB) is not enforceable by any organization, it is a voluntary behavior of employees which promotes the effective functioning of any organization. Organizational citizenship behavior is a multi-dimensional concept. Due to individual behavior and prevailing circumstances, OCB may vary from one organization to another organization or from one section to another section. In line with that, the present study explores the instrument for assessing organizational citizenship behavior in primary and high school teachers in Amritsar. The study has used a descriptive research design and a quantitative approach. The analysis of the data was made with the help of the exploratory and confirmatory factor analysis. The analysis of the data clearly revealed the understanding of different dimensions of organizational citizenship behavior in the context of school education.

Authors: Dochev Docho , Metodiev Lubomir
Published: July 2021

New data on the ammonite genus Pseudokossmaticeras Spath, 1922 have been obtained from several uppermost Campanian–lower Maastrichtian strata of the Fore-Balkan Mountains (Bulgaria). A review of the earlier Bulgarian records of the genus is also presented. The following species are here described and illustrated: Pseudokossmaticeras brandti (Redtenbacher, 1873), P. galicianum (Favre, 1869), P. muratovi Michailov, 1951 and P. tercense (Seunes, 1892). Our newly obtained ammonite records were constrained by the inoceramid zonation that has recently been proposed for successions of the Fore-Balkan area. Hence, the Bulgarian data are of importance for correlation with other occurrences of Pseudokossmaticeras across Europe.

Authors: Samadashvili Malkhaz
Published: July 2021

We studied the fruitfulness of Georgian Oak in Kakheti Region: in the gorge of the river Batsara in Akhmeta municipality at an altitude of 650-700m above the sea level, with oak dominance in a grove represented by a slope of up to 150 slopes of south-western exposure. Akhmeta municipality of Kakheti region was selected for the study of the issue, where in two different ecotopes and forest-type groves, sample areas with a size of 50 X 50 m were taken..In addition, we have divided the model tree drills allocated to the sample areas into two parts, namely, the parts facing the north and south exposures, and several sections of the tree trunk - the lower, middle and upper sections. Separately, we studied the seed yield and the difference between these indicators in terms of both exposure and vertical parts of the exercise - both quantitatively and by weight. We also observed the shape, size and other characteristics of the oak fruits on the sample areas, according to which the shape of the oak is oval, slightly elongated, with an average size of 2.8 cm. Length and 1.1 cm. Width. On average, 655 pieces (65.5%) of the fruit were found to be fit - healthy, and the rest (34.5%) - underdeveloped, damaged and incapable of emergence. These indicators are of great importance in the production of forestry and cultural works. In all sample areas, due to the better quality of insolation, the oak productivity is better in the southern part than in the north. With proper protection and care in the Georgian oak groves of Kakheti, it is possible to get an average of 1 ton of fruit per 1 ha, which is quite enough to achieve the best indicators of its natural renewal and to prevent these difficult problems. As we can see from the Georgian oak cultivations we have studied, in the vicinity of Akhmeta municipality (Batsari River gorge) it is possible to get an average of 1 ton of seed material, which is quite enough to get a reliable adult in terms of protecting the farm and promoting natural renewal.
For the Linguistic Conceptualization of Social Humor
Authors: Garibashvili Manana
Published: July 2021

Humor plays an important role in people's lives, which helps them to communicate and share their feelings and thoughts among each other. Jokes and various humorous utterances are a form of communication that is constantly shared in the process of social interaction. That is why humor is, to some extent, recognized as a social phenomenon.Since humor covers all areas, social media is no exception, as the latter is the most powerful tool of communication in the modern global world. People joke almost on everything despite difficult socio-economic circumstances and pandemic is no exception.The main goal of our research was to observe and analyze the so-called pandemic-related posts on social networks, particularly Facebook and to make their thematic and linguistic analysis. COVID 19 posts turned out to be quite diverse and very interesting. The observation has revealed that most of the posts on the social network concern the family relationships that are full of humor or sarcasm. This is not so surprising as people were forced to be locked in a family environment, That’s why numerous examples of this type have been gathered around this very topic. Interesting materials on educational and travel topics were also found during the study.Linguistic analysis of texts from social media, more precisely identification and analysis of the linguistic and literary means of expression, appeared to be very interesting.The research has revealed that various stylistic means such as repetition (parallel constriction), metaphors, comparison/simile, metonymy etc. are frequently used for constructing COVID 19 texts in social media. Thus, the analyzed examples are very interesting material from a psycho-linguistic point of view.

Published: July 2021

The semantic and Lingo-cultural analysis of the synonymic et for cares is discussed in the article. Georgian and English synonymic dictionaries are used as an analytic source. Studying synonyms has quite a long history. Linguistic observation of such items in different systematic languages is very interesting. We consider the difference which exists in the Georgian and English languages as structural-semantic, as well as lingu-cultural point of views. Synonyms are the part of lexical-semantic system of a language and the main point is shown in their absolute or partial coincidence. Their study allows us to have the access to a huge reserve depictive means of a language and gives us the opportunity to show them in a methodological way, which is “very crucial for learning our mother tongue as well as a foreign language”(Jorjaneli. K. 2006:6).While making a linguo-cultural analysis, the focus is mainly point on the question of what this notion means in different languages, what does it imply to, how is it expressed by; how does one language differ from another based on their linguistic portraits.As the observation on synonyms has revealed, the usage of substantial adjectives and zoonyms in the caress-endearment speech is universal for these two languages. Of course, individual words aso participate, which is the result of the linguo-cultural characteristics of each language. For example, addressing words like the following ones are very specific in English : Sweetie-pie( a sweet patty), bantam( bantam is associated with the breed of a little domestic hen), minuscule ( this is one of script varieties. It is used while showing an affection as a sign of something very little, insignificant), and in Georgian we can find - შენი ჭკუისა! ( Sheni chkuisa) მიტირე (mitire) / მტლად დაგედე (mtlad gadagede) / ჭირი მოგჭამე(chiri mogchame) / ჭირი მოგპარე (chiri mogpare) and so on.

From the medieval past we can single out several kings-poets, kings-scientists and scholars, education reformers, of whom Vakhtang VI deserves great respect.Versatile and varied turned out to be his genius and spectacle as well. King Vakhtang's intellect was accessible to completely different fields of science, such as history, jurisprudence, philosophy, astronomy-astrology, chemistry, medicine, grammar, textology, pedagogy. Not to mention the writing, where he said a decent word. Despite the difficult political situation, King Vakhtang VI still managed to create a prosperous cultural and educational environment in the country. With his initiative and support, the first printing house was established in Georgia in 1709. With the revival of the printed word, writing opened up vital space, giving more thought to thinking.By printing "The Knight in the Panther's Skin" the foundation was laid for the scientific study of the text of the poem - the work of restoration, the foundation was given to the most important field - Rustvelology.The literature of the Renaissance period is characterized by a number of novelties associated to the name of the King Vakhtang VI. The King, endowed with creative talent, contributed in every way to the development of new fields of science, the introduction of new themes and genres in literature. Understanding the national problem, trying to establish it and turning it into a spiritual need is the niche of Vakhtang's creativity.The only spiritual refuge of the king tired of life was the Christian faith. "The elaboration of religious themes, the cry to God, in addition to bringing spiritual peace to the deeply believing poet, at the same time he promoted the ideas of Christianity among the people and strengthened the religious faith.King Vakhtang VI not only enriched the Georgian literature with his original works, but also greatly contributed to his translation activities. His role in the development of lexicography was also great.The genius of Vakhtang VI can be discussed endlessly. It means a lot even to the fact that the history has survived in the name of the "lawgiver" king.

Circuit Mechanisms of Disease
Authors: Cheyne Juliette
Published: July 2021

My research focusses on how brain cell activity controls behaviour and what happens when this goes awry in disease. We utilise cellular recording in live mice (‘in vivo’) using a range of different imaging technologies. We have custom-built two specialised microscopes for this purpose – a two-photon microscope that allows high resolution deep imaging, and a ‘mesoscope’ with a wide field of view that is capable of imaging the entire mouse cortex. In addition, we use minaturised microscopes ('miniscopes') to record cellular activity in freely moving animals. These techniques allow us to track activity in the brain in real-time and relate the activity to behaviour or sensory input. Our current research is investigating on Autism Spectrum Disorder, Alzheimer’s disease, and Spinal Cord Injury.

Published: July 2021

Aim. Improve the results of diagnosis and surgical treatment of Hirschsprung’s disease in the neonatal period.

Materials and methods. The article presents an analysis of the diagnosis and results of surgical treatment of 15 children with Hirschsprung’s disease in the neonatal period, in the Department of Neonatology and Neonatal Surgery of the Scientiﬁc Center of Pediatrics and Pediatric Surgery from 2017 to 2020.

Results. All children were found to have a rectosigmoid form of the disease. 10 (66.6%) newborns underwent radical surgery-transanal endorectal proctoplasty according to Svenson-like. Immunohistochemical examination with the use of calretinin conﬁrmed Hirschsprung’s disease in all operated children.

Conclusions. Our results of surgical treatment in the neonatal period indicate that early diagnosis and early surgical correction contribute to the rapid restoration of gastrointestinal motility, and the method of choice is Svensonlike transanal endorectal proctoplasty, which has proven to be an effective and gentle method of surgical correction for this pathology. Also, the use of immunohistochemical studies with calretinin is a highly sensitive diagnostic method.

Published: July 2021

Aim. To assess the effect of iron deﬁciency anemia on the state of the oral mucosa in pregnant women.

Materials and methods. On the basis of the State Institution “NKI of Dentistry and Maxillofacial Surgery” of the Ministry of Health and the SZN of the RT, a clinical assessment of the effect of moderate iron deﬁciency anemia (IDA) on the state of the oral cavity was given in 48 pregnant women, where the hemoglobin level was below 100 g / l. The nature and severity of lesions of the oral mucosa were determined. Disturbances of taste sensations were assessed, a quantitative assessment of the varieties of taste disturbances was made, the nature and tonality of the color of the tongue were established.

Results and its discussion. In 48 examined women with IDA of moderate severity with hemoglobin below 100 g / l, local color changes were revealed on the anterior part of the tongue in the form of a bright red color. Paresthesia of the tongue was detected in 39.6% of women, for whom the most characteristic signs were burning sensations, tingling, tingling, and bursting. Sometimes these signs intensiﬁed with mechanical irritation - brushing teeth. The survey showed that 64.2% had a violation of taste sensations. The phenomenon of paresthesia of the tongue was in 39.6% of women; in 22.4% of women, a condition accompanied by a perversion of taste, dysgeusia, was recorded.

Conclusion. Iron deﬁciency anemia in pregnant women leads to signiﬁcant changes in the oral mucosa in the form of pallor of the oral mucosa, paresthesia, impaired taste sensations (hypogeusia, dysgeusia), thinning of the epithelial layer and papillae of the tongue, difﬁculty in swallowing due to dry mouth, as well as whitish color gums mainly in the projection of the roots of the teeth.
