Authors: Rose P. Leema , Sarojini V. , Biji G. D 
Published: March 2024

The increasing incidence of cancer cases and multi-drug-resistant bacteria, which are major threats to humankind, forces the research world to innovate new molecules to deal with them. The main aim of the present work is to prepare silver nanoparticles using macroalgal polysaccharides and to study biological activities. The silver nanoparticles (NPs) were prepared using polysaccharides extracted from the marine macro alga Portieria hornemannii by stirring them with 1 mM silver nitrate after 24 h at 90 ºC. The formed silver nanoparticles were characterized using UV-visible spectrophotometry, Fourier transform infrared spectroscopy (FTIR) analysis, Transmission Electron Microscopy (TEM) analysis, selected-area electron diffraction (SAED), and Energy Dispersive X-ray (EDX) analysis. UV-visible spectrum analysis revealed a surface plasmon peak at 380 nm, showing the development of silver nanoparticles. The nanoparticle size varied between 40 and 50 nm and the functional group was analyzed using FT-IR spectrum. The broadband was observed at 3304 cm-1 (hydroxyl and amino group) and the narrow band was observed at 2907 cm-1 (C–H stretching vibration), 1657 cm-1 (stretching of carbonyl groups), and 1001 cm-1 (C–O stretching vibration). The crystalline nature of silver NPs was confirmed by SAED. EDX analysis reveals the purity and the chemical composition of silver NPs. Nanoparticles were highly effective against Proteus mirabilis (24 mm zone of inhibition) and Bacillus substilis (24 mm zone of inhibition). The anticancer activity of the silver nanoparticles tested against colorectal adenocarcinoma cell lines increased at increasing concentrations of nanoparticles.

Published: March 2024

Introducción. El infarto medular es una patología severa e infrecuente, que representa el 1% del total de ictus isquémicos, siendo además una complicación rara de distintos procedimientos quirúrgicos. Es causado por la interrupción aguda del flujo sanguíneo de la médula espinal, manifestándose con déficits neurológicos clínicos relacionados con el territorio vascular afectado.
Métodos. Presentamos el caso de un paciente de 80 años, con factores de riesgo cardiovascular, quien presenta en día postquirúrgico 13, tras colocación de endoprótesis vascular por aneurisma toraco-abdominal aparición brusca de paraparesia con progresión a paraplejía e hipoestesia en ambas extremidades inferiores. Angio-TC de aorta descarta complicación local en la endoprótesis. RM medular mostró imágenes compatibles con Infarto agudo de médula dorsal desde el nivel D9. El paciente no fue subsidiario de tratamiento revascularizador. El tratamiento consistió en medidas de soporte.
Resultados. Al alta el paciente presentaba paraplejia e hipoestesia de ambas extremidades inferiores con incontinencia fecal y urinaria.
Conclusión. El infarto de la médula espinal puede estar limitado a un territorio vascular o estar más extendido según su patogenia. La afectación de la arteria espinal anterior es la más común y se caracteriza por déficits motores bilaterales y pérdida de la sensibilidad termoalgésica, pudiendo llegar a producir un gran impacto en la calidad de vida de los pacientes. Su etiología es variada, incluyéndose la cirugía aórtica dentro de sus causas. La RM es muy útil para su diagnóstico y actualmente no existen guías clínicas para el tratamiento óptimo.

Development of ballroom choreographic culture in Ukraine in the 2010s–2020s
Authors: Malynovska N. , Semenova N. , Shkuryeyev K. 
Published: March 2024

The purpose of the study is to reveal the consequences of the challenges of the 2020s, namely the COVID-19 pandemic and full-scale invasion of the Russian Federation with partial occupation of territory, migration of population, expansion of zone of battle actions and the threat of aerial attacks for the entire country. All this had an impact on the ballroom choreographic culture in Ukraine.
The methodology is based on the principles of a system-synergistic approach. The main methods applied were participant observation, analysis, generalization and systematization of the authors’ many years of dance, organizational and pedagogical experience.
The results. The challenges of the 2020s, namely the COVID-19 pandemic and the full-scale aggression of the Russian Federation with partial occupation of the territory, population migration, expansion of the combat zone and regular missile terror throughout the country, have significantly affected the ballroom dance culture of Ukraine, in particular, changed the country’s dance map, limiting and partially making it impossible to hold competitions and training in the combat zone and eastern regions that are unprotected from sudden missile attacks. The socio-political upheaval has prompted the Ukrainian dance community to seek national self-identification, giving rise to the creation of imaginative and meaningful compositions through ballroom dance that would embody the pressing issues of our time, including the themes of war, occupation and the challenges they have caused. At the same time, the national organization system of the ballroom dance tournaments and training process has revealed significant shortcomings. In particular, the problem of upgrading to an international class of dancing in the context of the pandemic and then the war, which was felt in previous years, made it impossible for dancers in the eastern regions of Ukraine to develop, as they were deprived of the opportunity to regularly participate in competitions.
The scientific novelty of the study is to analyze the modern tournament and training system of sports ballroom choreography in Ukraine in the last decade and to identify the problems that hinder the development of this type of dance art and have become especially acute during the challenges of the 2020s.
The practical significance. Some provisions of the article can be used for updating Ukrainian ballroom dance competitions in accordance with current social and political conditions.
Prospects for further research. A number of problems require scientific and theoretical comprehension, in particular, the place of ballroom dance in Ukrainian culture, its philosophy, images, styles, principles and expressive means of dance composition. The methodology of dancer’s physical training, based on the peculiarities of sports ballroom dance, requires separate research.
Converting dramatic text to screen language
Authors: Miroshnychenko M. 
Published: March 2024

The purpose of the article. The study considers film adaptation as a way of interpreting a literary text written for stage production by means of cinematography. The article focuses on the role of the director, his own vision of events and characters in the process of transcoding a work of art into the language of cinema. The features of the dramatic text (monologues, dialogues, author’s remarks, description of characters, division of the work into scenes and acts), the means by which the dramatic work affects the viewer/recipient are highlighted. The article, based on the works of William Shakespeare “Macbeth” and Sophocles “Oedipus the King”, examines the originality of the transformation of a dramatic text into the language of cinema. The article outlines the theoretical basis of film poetry, which allowed directors and screenwriters to practically embody the film adaptation of stage drama. The results of the study showed that the dramatic text and its film interpretation indicate the author’s and director’s reception.
The methodology. The author uses analysis (theoretical works on screenwriting and directing, research in the field of art history), observation (the creative process in cinema), comparison (the literary source and the finished film), systematization (techniques for transforming the dramatic literary source into a screen work), modeling the principles of directing and script.
The results of the research can be used in educational programs of art universities and creative workshops, as well as in the practical work of directors, screenwriters, cultural scientists, and art historians. The paper provides examples that form the basis for practical principles that can help in creating film adaptations based on plays.
The scientific novelty lies in the fact that the study represents a unique scientific contribution, carrying out a thorough study of the process of transforming a dramatic work into a film script. It is important to note that this research goes beyond the script, delving into the essence of the director’s vision. It provides for a comprehensive understanding and systematization of various directing techniques used throughout the entire film adaptation process.
Cultural orientation of the “mimicry” society. The search for national self-identification in contemporary screen art
Authors: Ponomarenko O. 
Published: March 2024

The purpose of this article is to study the peculiarities of the behavioral manifestation of Ukrainian screen characters in order to identify qualitative features characteristic of the Ukrainian mentality. This will allow us to determine the themes of screen works that will be relevant for the contemporary Ukrainian viewer, which will improve the qualitative and quantitative characteristics of Ukrainian audiovisual art.
The methodology. Five scientific sources were studied (one dissertation, one collective scientific work, and three scientific articles), which allowed us to analyze the relationship between the behavioral reactions of the screen character and the nature of fear that was formed in the process of adaptive transformation of society. On the example of the films “The Guide” by Oles Sanin, “The Red” by Zaza Buadze, and “The Rising Hawk” by Leonid Osyka, the main themes and conflicts that characterize Ukrainian identity were identified and formulated.
The results of the study demonstrate certain stable psychophysical reactions displayed by the screen character in a situation of existential conflict caused by the historical development of Ukrainian society. The nature of fears, as the main instrument of the motivating impulse in the process of forming cognitive, emotional and behavioral reactions, is determined by the level of the scale of the hero’s own identity recognition.
The scientific novelty of the study lies in the author’s attempt to consider the conflict of the Ukrainian screen hero as a value clash between the goal-setting of a free individual and a society that has undergone adaptive transformations, which is realized through the manifestation of a certain behavioral nature of screen characters.
The practical significance of the research findings will help in the process of creating new screen works. This will increase the attention to Ukrainian cinema.

Authors: Belihu Gebremedhin Desta , Moges Wudneh Ketema , Yimer Asamin Kasiye 
Published: March 2024

Objective: To investigate the associated factors that affect time to relapse in patients with schizophrenia at St. Amanuel Mental Specialized Hospital, with recurrent events model.Material and Methods: A hospital-based retrospective review of the medical records of 332 patient with schizophrenia, covering a two-year period, were examined. Parametric frailty models were used to determine the correlation between discharge times and relapse, and to identify risk factors using R-software. Results: The distribution number of relapses was 162, and the median survival time of patients with schizophrenia was 665 days. The unobserved heterogeneity in patients and correlation between relapses, as estimated by the Weibull-gamma frailty model, was p-value≤0.001 and Kendall’s Tau (Γ)=0.498. This indicated that there was heterogeneity among participants and a correlation between relapses. The final model showed that the effect of psychiatric comorbidity (hazard ratio (HR)=6.522, p-value≤0.001), employment status (HR=5.334, p-value=0.001), history of suicide attempt (HR=2.167, p-value=0.003) and history of traditional treatment (HR=1.973262, p-value=0.021) had a significant effect on the hazard time to relapse. Onset Age of schizophrenia and drug adherence were not predictive. Subsequent relapses are likely dependent on both the first and previous relapses.Conclusion: Comorbidity, employment status, history of suicide attempt and history of traditional treatment are imperative risk factors influencing the hazard of time to relapse, which increases the risk of relapse.
Zespół apatii w chorobach neurologicznych – stan wiedzy i aktualne kierunki badań
Authors: Roessler-Górecka Magdalena 
Published: March 2024

Cel: Apatia bywa wskazywana jako symptom w różnych jednostkach chorobowych m.in. na gruncie psychiatrii, jednak od kilku dekad wyodrębnia się ją także jako niezależny syndrom towarzyszący wielu schorzeniom neurologicznym. Choć nadal pomijany w obowiązujących klasyfikacjach medycznych, zespół apatii stanowi przedmiot licznych analiz teoretycznych i klinicznych. Upowszechnienie wiedzy na jego temat wśród klinicystów – w tym możliwości jego rozpoznawania i różnicowania, zwłaszcza od depresji – ma podstawowe znaczenie dla efektywności oddziaływań terapeutycznych. Praca prezentuje proponowane w literaturze definicje oraz kryteria diagnostyczne zespołu apatii. Przedstawia dane dotyczące jego częstości w różnych schorzeniach, związków z patologią mózgu oraz szeregiem zmiennych klinicznych.
Tezy: Współczesne koncepcje podkreślają syndromiczny charakter, wielowymiarowość zespołu apatii oraz powiązania z szeroko rozumianymi funkcjami płatów czołowych. Domeny funkcjonowania, w których mogą być ujawniane objawy apatii, obejmują sferę poznawczą, emocjonalną, interakcje społeczne oraz zachowanie (inicjowanie i podtrzymywanie dowolnej celowej aktywności). Wskazuje się na relatywną niezależność zespołu od depresji, podkreśla znaczenie jako czynnika prognostycznego rozwoju otępień, związek z jakością życia, efektywnością rehabilitacji oraz psychologicznym obciążeniem opiekunów. Poszukując mózgowego podłoża apatii rozpatruje się szereg częściowo nakładających się procesów oraz znaczącą rolę jąder podstawy i wybranych obszarów kory przedczołowej.
Konkluzja: Dla wystąpienia symptomów apatii kluczowa może być dysfunkcja dowolnego ogniwa złożonych obwodów przedczołowo-podkorowych, czym tłumaczy się wysoką częstość omawianego zespołu w chorobach mózgu, zwłaszcza przebiegających z uszkodzeniami jąder podstawy i/lub kory przedczołowej. Zróżnicowanie nasilenia symptomów w poszczególnych domenach oraz powtarzalność profilów nieprawidłowości obserwowana zależnie od analizowanej jednostki chorobowej i/lub lokalizacji patologii mózgu skłaniają do poszukiwania podtypów zespołu apatii.

Relevance. In recent years, this crop, which is cultivated in order to obtain oil and fiber, is gradually gaining its abundance, increasing the acreage. In many agro-industrial enterprises, hemp is being introduced into crop rotations, and plants for its processing are being built. This culture plays a huge national economic importance and finds its application in various industries. One of the main elements of cannabis cultivation technology is the use of highly productive varieties.Methodology. The laying of field experiments, related observations and records were carried out in accordance with existing methodological guidelines for conducting field and vegetation experiments with cannabis.Results. The most optimal variety for the conditions of the Southern forest-steppe zone of the Republic of Bashkortostan is the Nadezhda variety. This variety is superior to the others (Vera and Omegadar-1) in terms of quality and quantity. For example, from the 2021–2022 studies on biomorphometric indicators, it follows that Nadezhda achieved the best indicators for: plant height (194.50 cm and 194.33 cm), technical stem length (160.60 cm and 162.45 cm), inflorescence length (33.90 cm and 31.88 cm), stem diameter (0.8–0.9 cm), the number of internodes (8–9 pcs.), the average length of internodes (12.5 cm and 19.87 cm). The weight of 1000 seeds was 17.01 g and 18.10 g, oil content — 32.89% and 33.72%, yield — 0.88 t/ha and 1.71 t/ha. The greatest results in 2022 are associated with agrometeorological conditions.

Published: March 2024

Relevance. Sugar beet is one of the raw materials from which granulated sugar is produced, and it, in turn, is one of the indicators by which the food security of any country is assessed. In 2020, European countries produced 47.6% of the total global volume of sugar beet, Asian countries — 18.6%, America — 13.3%, the Russian Federation — 13.7%, African countries — 6.7%. At the same time, the share of sugar beet production in global production increased in Asian countries (from 15.9% in 2010 up to 18.6% in 2020), in the Russian Federation (from 10.1 to 13.7%), in African countries (from 4.6 to 6.7%). A decrease in sugar beet production was noted in European countries — from 55.4% in 2010 to 47.6% in 2020, in American countries — from 14 to 13.3%. In the Russian Federation, sugar production per capita generally meets not only rational consumption standards, but also all criteria for food self-sufficiency. The excess of actual consumption over rational consumption in Russia is 62.5%. The lowest sugar beet production volumes are observed in countries such as Greece, Portugal, North Macedonia, Pakistan, Azerbaijan, Turkmenistan, Kazakhstan, Moldova, Kyrgyzstan, and some others.Results. The results of the study showed that in order to increase the economic indicators of sugar beet production, Russian commodity producers need to implement a policy of intensification of agricultural production along with updating the material and technical base using modern agricultural technologies and the development of their own breeding and genetic centers.
