When teachers write and heal together
Authors: Vega Vanessa E. , Perry Tonya B. , Pryor Naomi , Henderson-Green Sonjanika
Published: July 2023

The spring and summer of 2020 were rife with tension emanating from hate speech, racial violence, and a global health pandemic. Educators deliberated over the uncertainties of equitable access to learning, healthcare, and wellbeing. This article will describe how the Red Mountain Writing Project created a third space (Gutierrez, 2008) grounded by Critical Race Theory (CRT) in education (Solorzano & Delgado Bernal, 2001; Solorzano & Yosso, 2001) and Historically Responsive Literacy (Muhammad, 2020) to center the lives of teachers, their experiences, and their stories during a tumultuous time. The authors will share how they built and maintained a supportive virtual space for teachers to critically examine and reflect on their lived experiences, social awareness, sense of agency, and anti-racist teaching and writing practices. Now, after more than two years, teacher-writer communities are especially needed – third spaces where teachers from diverse backgrounds can hold space together and engage in writing to heal, find joy, empathize, and amplify their experiential knowledges.
Dług publiczny krajów Unii Europejskiej w okresie pandemii COVID-19
Authors: Górniewicz Grzegorz
Published: July 2023

W wyniku kryzysu wywołanego przez pandemię COVID-19 nastąpił dynamiczny wzrost długu publicznego krajów Unii Europejskiej. Bezpośrednią przyczyną okazały się ogromne deficyty budżetowe, mające swoje źródło we wprowadzanych w poszczególnych krajach ograniczeniach życia gospodarczego i pomocy finansowej państw dla najbardziej poszkodowanych branż. W najbliższym czasie prawdopodobnie należy oczekiwać dalszego wzrostu zadłużenia, który w istotnym stopniu będzie wynikał z zaciągania nowych zobowiązań finansowych na potrzeby odbudowy gospodarek krajów UE po kryzysie.Celem opracowania jest przedstawienie zmian w wielkości długu publicznego w warunkach pandemii COVID-19 i identyfikacja implikacji związanych z jego szybkim wzrostem. Oprócz analizy danych statystycznych uwagę skoncentrowano na przyczynach narastania zjawiska, programie odbudowy gospodarki Next Generation EU oraz wpływie zadłużenia na wzrost gospodarczy. Głównateza pracy głosi, że koronawirusowy kryzys spowodował istotny wzrost długu w krajach Unii Europejskiej. Dla zrealizowania przedstawionego wyżej celu pracy i uargumentowania postawionej tezy została wykorzystana metoda badawcza określona jako komparatywna analiza opisowa.
Nierówności na rynku pracy a zróżnicowanie regionalne w Polsce
Authors: Piekutowska Agnieszka
Published: July 2023

Celem artykułu jest wskazanie związku pomiędzy istniejącymi nierównościami na rynku pracy a zróżnicowaniem regionalnym polskiej gospodarki. W opracowaniu przybliżono zagadnienia dotyczące różnic w poziomie rozwoju gospodarczego. Wyodrębniono przy tym regiony najsłabiej rozwinięte. Podkreślono także trwały charakter istniejących dysproporcji, a co za tym idzie konieczność identyfikacji czynników odpowiedzialnych za powstałe różnice. Analiza literatury przedmiotu wskazała, że istotną rolę odgrywają nierówności na rynku pracy. Dlatego też, w kolejnej części opracowania zwrócono uwagę na rolę edukacji w rozwoju gospodarczym. Poziom wykształcenia ludności określa bowiem jakość kapitału ludzkiego i tym samym staje się istotnym czynnikiem rozwoju regionalnego. Przeprowadzona analiza statystyczna potwierdziła, że regiony najsłabiej rozwinięte dysponują niskiej jakości kapitałem ludzkim, co utrudnia zmniejszenie istniejących dysproporcji rozwojowych. Z punktu widzenia zróżnicowania regionalnego istotne okazały się również nierówności w dostępie do ofert pracy. Zapotrzebowanie na pracowników determinuje przy tym natężenie podmiotów gospodarki narodowej w rejestrze REGON. Pod tym względem również zaobserwowano istotne różnice w skali regionów. Wynika z nich, że regiony najsłabiej rozwinięte mają ograniczony dostęp do ofert rynku pracy, nie tylko ze względu na niską jakość kapitału ludzkiego, ale także niski poziom przedsiębiorczości. W ten sposób, analiza literatury i danych statystycznych pozwoliła stwierdzić, że zarówno nierówności edukacyjne, jak i nierówności w dostępie do ofert pracy pozostają istotnymi determinantami zróżnicowania regionalnego w polskiej gospodarce.
Relações públicas e jornalistas
Authors: Cavaco Suzana
Published: July 2023

Num tempo marcado pela conectividade, transparência e falta de confiança, enquanto o jornalismo está mergulhado numa crise sem precedentes, os Relações Públicas são chamados a gerir a reputação e a assegurar/restaurar a confiança nas marcas. Tendo em vista dar um contributo para a clarificação dos objetivos/motivações normativos destes dois campos socioprofissionais, o presente artigo, explora códigos deontológicos de âmbito supranacional, recorrendo à análise de discurso. Verificamos que, apesar da ausência de conflitos de valores/princípios, há diferenças nos propósitos/motivações normativos, sugerindo preocupações e compromissos sociais diferentes, que podem ajudar a delimitar/demarcar fronteiras entre estes dois “parentes próximos”. O estudo sugere, entre outros, que enquanto o jornalismo luta por ser respeitado; a preocupação central em Relações Públicas é ser respeitável.

Published: July 2023

Microalgae are gaining importance in the agriculture sector because of their biostimulant activities and thereby increasing crop and vegetable yields worldwide. In the current study, intact microalgal cells were used as bio-stimulants for Cucumis sativus root treatment in a soilless agricultural system inside a Dutch polyhouse along with routine nutrients. The control sets with routine nutrients and with only D/W were put to study the exact effect of microalga on the
growth of the cucumber plant. The average length of the biostimulant treated cucumber climber was 12.25% more than nutrient set, which itself showed 48.28% more growth than the control set. Similarly, biostimulant treated set showed an increase in the stem diameter (10%), the number of
leaves (37.66%), and the number of floral buds (39.47%) as compared to nutrient set, which themselves exhibited superior parameters than the control set. The numbers of flowers were 100% and fruits were 77.78% more in the biostimulant treated set than in the nutrient set. When the
pigment profile was studied, the biostimulant treated set showed increased chlorophyll a (23.77%), chlorophyll b (68.78%) and decreased carotenoids (65.75%) content as compared to the nutrient set. Microscopic observation of roots of microalga biostimulant treated set revealed microalga-root association. To the best of our knowledge, it is the first report of the microalga-root association in C. sativus along with a positive impact on the overall growth and yield of cucumber plants under
soilless conditions. The findings have the potential to lay the groundwork for a novel microbe-root interaction between microalgae and plant roots (Phyco-rrhiza).
"BARBED-WIRE BOUNDARIES": HIDDEN CURRICULUM, FIRST-GENERATION AND LOW-INCOME ENGINEERING STUDENTS, AND INTERNSHIP ACQUISITION
Authors: Yang Jerry A. , Towles Joseph D. , Sheppard Sheri D. , Atwood Sara A.
Published: July 2023

Engineering industry internships provide significant benefits for undergraduate engineering students'
careers. First-generation and low-income students (FGLI) are one group of marginalized students who access internships at lower rates compared to their non-FGLI peers; however, the reasons for this gap have not yet been explored in the literature. In this article, we investigate the internship acquisition experiences of FGLI engineering undergraduate students at a mid-sized private university in the western United States. We conducted ten semi-structured interviews to capture FGLI engineering students' experiences encountering and navigating the process of obtaining an internship. Our findings highlight the ways in which much of the knowledges surrounding the internship search and recruitment process are implicit and how this implicit hidden curriculum and technocratic culture create structural barriers to internship access for FGLI engineering students. We present a structural critique of internship recruitment through the framework of hidden curriculum and propose that companies and engineering education institutions work together toward transparent modes of evaluation for internship recruitment.
Toward a Broader View of Health in the Anthropocene: The COVID-19 Syndemic and the Clash of Cosmographies in Mato Grosso do Sul, Brazil
Authors: Dias-Scopel Raquel , Scopel Daniel , Langdon Esther Jean
Published: July 2023

The continual expansion of developmental frontiers has impacted dramatically upon Indigenous health in Brazil. When the COVID-19 pandemic struck in Mato Grosso do Sul, its Indigenous populations were already living in circumstances of environmental degradation, food insecurity, racism, and structural violence. The synergistic interaction between the SARS-CoV-2 virus, other pathogens, and biosocial factors resulted in what Singer (2010) terms as ‘syndemics’. In the case of Mato Grosso do Sul, it brought about a substantial increase in the disease burden of Indigenous Peoples, where child malnutrition, obesity, hypertension, respiratory and parasitic diseases, and maternal mortality appear at higher rates than in the non-Indigenous population. This Research Article discusses the coping and participatory strategies that were employed by Indigenous Peoples early in the pandemic. Efforts by Indigenous Peoples to address the pandemic reveal ‘a clash’ between Indigenous and Colonial cosmographies with regard to notions of the body and health. Considering the Indigenous perspective on the relation between territoriality and health, the analysis highlights asymmetries of power and embodied vulnerabilities and the limits of the Anthropocene as a global perspective.
Toxic Legacies and Health Inequalities of the Anthropocene: Perspectives from the Margins
Authors: Calestani Melania
Published: July 2023

Based on research in Matamoros (Mexico) and Naples (Italy), this article critically deconstructs embodiments and social histories of toxicity, addressing uneven power relations and health inequalities generated through late capitalism of the Anthropocene. By focusing on food and water consumption in regions at the margins of borders and defined as toxic wastelands, it sheds light on the multidimensional power structures of the global economy. Whether through reference to the illegal dumping of toxic waste by mafia-structured organised crime groups, or the contamination caused by foreign-owned assembly plants, the article illustrates how mechanisms taking place in the individual realm are ‘subsumed’ (Breihl 2019, 33) within more complex historical, economic, and environmental processes. These two case studies are the point of departure to reflect upon the undisclosed but powerful impact that commercial determinants of health have on individuals’ wellbeing, feeding profound north–south inequalities.

Comparación de algoritmos de sustracción de fondo en soluciones para la gestión del tráfico urbano de vehículos y peatones basadas en visión computacional.
Authors: Barboza Rogério Santino , Paschoalin Filho João Alexandre
Published: July 2023

La creciente población y número de vehículos en las grandes ciudades han generado congestionamientos y complicaciones en el tráfico, cuyas soluciones son costosas e ineficaces a largo plazo. Para mejorar las condiciones del tráfico urbano, incluyendo la automatización del sistema de semáforos a través de la tecnología de visión computacional, se ha buscado la monitorización inteligente del tráfico. Este estudio tuvo como objetivo desarrollar un sistema automatizado y sincrónico de análisis de tráfico, comparando el rendimiento de diferentes algoritmos de sustracción de fondo (BGS). Se creó un software para analizar los algoritmos BGS en términos de conteo de vehículos, registro y sentido de dirección, mientras que otro se desarrolló para detectar peatones. La revisión sistemática de la literatura de artículos publicados entre el 01/01/1970 y el 31/01/2023 demostró que el uso exclusivo de BGS no es lo suficientemente preciso para su aplicación en sistemas de semáforos o monitorización autónoma. Sin embargo, la combinación de BGS con aprendizaje automático y profundo es prometedora. Para mejorar la precisión y otras métricas, como falsos y verdaderos positivos, es necesario mejorar los filtros individuales y combinarlos con otras tecnologías.

Authors: Manzoli Anderson , Queiroz Altamira de Souza , Castro Carolina Maria Pozzi de , Stanganini Fabio Noel
Published: July 2023

El desarrollo de aglomeraciones humanas a lo largo de los años ha requerido la creación de nuevas leyes que buscan mejorar la gobernanza de los espacios públicos, fortaleciendo los mecanismos de articulación y coordinación entre los municipios que componen la región. Estas leyes incluyen la creación de consejos metropolitanos, planes de desarrollo integrado e instrumentos de gestión territorial, como zonificación, movilidad, salud, educación y uso del suelo. La implementación de estas leyes trae impactos y desafíos para la gestión pública y privada de las regiones metropolitanas, requiriendo soluciones integradas y sostenibles. El objetivo de este trabajo es analizar los impactos que las tecnologías emergentes pueden aportar al estudio de la gestión pública y el desarrollo de las regiones metropolitanas. Se utilizaron métodos de investigación cualitativa y revisión de literatura para desarrollar el artículo. Los resultados confirman la posibilidad de utilizar tecnologías modernas para mejoras en la gestión pública de las regiones metropolitanas, ya que las transformaciones sociales, culturales y tecnológicas han impactado directamente en la forma en que se gestionan las ciudades. Se concluye, por lo tanto, que la adopción de estas tecnologías de apoyo a la gestión puede y ha sido una solución para superar desafíos, buscando beneficios para la población, desarrollo estratégico y sostenible para el desarrollo de regiones metropolitanas.
Expansión Urbana En Ciudades Pequeñas: El Caso De Crissiumal/RS
Authors: Bertaluci Gabriela Luiza Leismann , Neckel Alcindo , Silva Thaísa Leal da
Published: July 2023

Las ciudades se han convertido en espacios urbanos complejos y dinámicos. En este contexto, las políticas territoriales municipales juegan un papel importante en el proceso de urbanización de las zonas de transición entre lo rural y lo urbano. Frente a eso, este artículo propone un estudio referente a una pequeña ciudad, ubicada en el noroeste del estado de Rio Grande do Sul: Crissiumal, buscando comprender el proceso de expansión urbana que ha ocurrido desde 2005 hasta la actualidad. La metodología se basa en la interpretación e investigación, a través de un marco teórico, levantamiento documental y legislativo, elaboración de mapas y análisis de los datos recolectados. A través de este estudio, fue posible percibir que, aunque la ciudad cuenta con un Plan Director, el documento no menciona lineamientos sobre los usos destinados a los barrios. Además, fue posible ubicar y analizar los fraccionamientos urbanos creados en el marco temporal de 2005 a 2023, además de comprender sus usos. Así, se pudo concluir que es importante contar con una adecuada planificación urbana, aún tratándose de pequeñas ciudades del interior, teniendo en cuenta aspectos como la cultura, la economía y la geografía, además de definir la tipología edificatoria para cada barrio.
Implicaciones de la verticalización en el confort térmico urbano: análisis predictivo a partir de simulaciones computacionales
Authors: Leal Limber Patric Santos , Barbosa Ricardo Victor Rodrigues
Published: July 2023

El presente estudio tuvo como objetivo analizar la influencia de la verticalización en el confort térmico humano en ambientes externos, a partir de simulaciones informáticas de escenarios urbanos hipotéticos en la ciudad de Arapiraca, inserta en el contexto climático de la región semiárida de Alagoas. Los procedimientos metodológicos adoptados caracterizan la investigación como predictiva. Los escenarios hipotéticos se simularon en el software ENVI-met 4.0, del cual se extrajeron los datos microclimáticos necesarios para el cálculo del índice de confort térmico del PET mediante el software RayMan Pro. Los parámetros urbanos analizados fueron la variación de altura y los retranqueos de las edificaciones. Los resultados fueron observados gráficamente y sometidos a análisis estadístico de regresión y correlación entre los valores del factor de cielo visible (FCV) de los escenarios urbanos y los valores del PET generado, donde fue posible identificar que el confort térmico de los usuarios del entorno urbano se explica del 70 al 95% por FCV, influenciado por la morfología del entorno. Además, los resultados mostraron que a menor valor de FCV, menor valor del índice PET, por lo que el escenario horizontal provocó un aumento del malestar al permitir una mayor incidencia de la radiación solar directa en la trama urbana. Los resultados de esta investigación apuntan a la importancia del sombreado que brindan los escenarios verticalizados, combinado con el enfriamiento evaporativo a través de masas vegetadas y cuerpos de agua, como estrategias bioclimáticas que coadyuvan directamente en las condiciones de confort térmico en ambientes externos en el período cálido y seco de ciudad de Arapiraca-AL.
Ethmoidal sinus osteoma associated with Pneumocephalus
Authors: Ayda Aly Youssef , Ayman Nada , Hassan Ali Elkiki
Published: July 2023

The most common causes of intracranial air are head trauma and neurosurgical procedures. Less common etiologies include infection due to gas-forming organisms, mucoceles, tumors, congenital neuroenteric cysts, and dural defects. Here, we present a case of an ethmoidal sinus osteoma associated with pneumocephalus. Osteomas of the paranasal sinuses are benign, often asymptomatic, tumors that progress very slowly. Endocranial development of an osteoma can breach the dura mata, allowing air to enter the cranium producing pneumocephalia which leads to severe neurological deficiencies. Pneumocephalia is an exceptional complication of osteoma.
A novel modified Khatter’s approach for solving Neutrosophic Data Envelopment Analysis
Authors: Mohanta Kshitish Kumar , Sharanappa Deena Sunil , Aggarwal Abha
Published: July 2023

The evaluation of the performance of decision-making units (DMUs) that use comparable inputs to produce related outputs can be accomplished through a non-parametric linear programming (LP) technique called Data Envelopment Analysis (DEA). However, the observed data are occasionally imprecise, ambiguous, inadequate, and inconsistent which may result in incorrect decision-making when these criteria are ignored. Neutrosophic Set (NS) is an extension of fuzzy sets which is used to represent unclear, erroneous, missing, and wrong information. This paper proposes a neutrosophic version of the DEA model, and a novel solution technique for Neutrosophic DEA (Neu-DEA) model. The possibility mean for triangular neutrosophic number (TNN) is redefined and modified the Khatter’s approach to convert directly the Neu-DEA model into its crisp DEA model. As a result, the Neu-DEA model is simplified to a crisp LP problem with a risk parameter (δ ∈ [0, 1]) that represents the attitude of the decision-maker towards taking risk. The efficiency score of the DMUs is computed by using various risk factors and divided into efficient and inefficient groups. The ranking of DMUs is determined by calculating the mean efficiency score of DMUs, which is based on various risk parameters. A numerical example is illustrated here to describe the suggested approach’s flexibility and authenticity and compared with some of the existing approaches.
The Emergence of Levallois Blade Industry in the Western Foothills of Tien Shan: Kulbulak Layer 24
Authors: Pavlenok G. D. , Kogai S. A. , Kurbanov R. N. , Mukhtarov G. A. , Pavlenok K. K.
Published: July 2023

We describe fi nds from layer 24 of Kulbulak, Western Tien Shan, excavated in 2018–2019. On the basis of the age of layer 16 (MIS 5e) and the geological context of the deposits, the profi le of the site was subdivided into paleogeographic stages. Layers 25–22 likely correlate with the warming period in the second half of MIS 7. Primary reduction in layer 24 industry was based on parallel uni- and bidirectional techniques, with wide and narrow-faced cores, and following the Levallois strategy. Tools include various side-scrapers, a point on a heavily retouched blade, a retouched blade, an atypical angular end-scraper, and blanks of bifaces. Parallels are found between those fi nds and contemporaneous industries of the Near East. Technologically and likely chronologically, layer 24 is intermediate between Late Amudian and Early Middle Paleolithic assemblages of the Tabun D stage. This is evidenced by a combination of non-Levallois and Levallois fl aking (the latter being predominant), by different types of blanks within the same reduction sequence, by a high share of blades among blanks, by bifacial pieces, by an elongated heavily retouched point, and by an atypical end-scraper.
Anti-Doping Rules as a Unique System of Legal Relations: Background and Regulatory Issues
Authors: Orlov A. A. , Gali A. A.
Published: July 2023

Coordinated efforts of the States and sports organizations to eliminate doping in sport all over the world have formed a unique legal model that stands out for high uniformity in its implementation and enforcement despite differences in national regulations, and this legal model continues to evolve. Erosion of the principles of amateurism, growing governmental interest in sport, concerns about the health of athletes have affected the shape of the modern anti-doping legal system. This study analyzes the key historical stages in the development of anti-doping rules and regulations, as well as the prerequisites for the formation of its modern legal principles and methods. The study details the first anti-doping rules adopted by the Jockey Club at the beginning of the 20th century and describes the legal activities of the International Olympic Committee, States and intergovernmental organizations on creating anti-doping rules and legislation before the adoption of the UNESCO Convention in 2005. Special emphasis is placed on the explanation of ideological and political influence on the development of anti-doping rules and assessing the roles of the main actors in the antidoping system.
Extraterritoriality of the Rodchenkov Anti-Doping Act and Its Impact on the Anti-Doping Regulatory System
Authors: Tikhonova V. V. , Mokhov A. A.
Published: July 2023

The paper examines the Rodchenkov Anti-Doping Act (Rodchenkov Act) and its impact on the World Anti-Doping Agency (WADA). WADA has a dominant status in the field of anti-doping regulation in sport and builds relationships with other actors in sport based on a hierarchy. Maintaining WADA’s status as the primary regulator and coordinator of anti-doping activities in sport appears necessary for the further effective development of anti-doping policy and maintaining parity between States in matters of anti-doping activities. However, extraterritorial application of the Rodchenkov Act challenges WADA’s position as the universal and exclusive entity responsible for coordinating the fight against doping in sport, and, therefore, this poses threats to the harmonized governance model of the anti-doping system by States. The paper examines the legal aspects of the Rodchenkov Act, its impact on the anti-doping regulatory system and the feasibility of introducing the extra-territorial principle of operation. The authors also analyze the first investigation under the Rodchenkov Act carried out in 2022 and the future prospects of its application. The authors focus on examination of permissibility of extraterritorial provisions of the Rodchenkov Act and the possible implications for the anti-doping system if the Rodchenkov Act is applied extraterritorially.
Legalization of Ethics in Sports and Disciplinary Liability for “Disrepute”
Authors: Vasilyev I. A.
Published: July 2023

The norms of ethics in sport have practically merged with the disciplinary norms of sports federations. However, the apparent identity of ethical duties and disciplinary duties has not resolved the existing problems of law enforcement. Ethical norms enshrined in the acts of sports federations must meet certain standards of law. In this case, we are referring to the general principles of legal certainty and proportionality, as well as some other related principles. These principles are the first and main guarantees for the subject of sport in case of a breach of an ethical obligation. They are used at different stages of disciplinary liability. Legal certainty protects against unclear ethical norms and unpredictable consequences of their use by sports federations. Proportionality obliges the measure of disciplinary responsibility not to exceed the necessary negative effect of coercion. The ethical obligation to abstain from disrepute is widespread in the acts of federations. The practice of non-disrepute has been intensified by geopolitical events of 2022. The examples of the practice on non-disrepute do not allow us to state that legal certainty and proportionality really protect in any situation from improper disciplinary liability. The tendency has appeared to understand the reputation of sports and sports federations through the prism of the public positions of a particular federation. Confrontation with such positions automatically creates the risk of disciplinary liability. Similarly, the test for real harm to reputation is ignored unlike potential harm or harm existing only in subjective judgements.

Published: July 2023

Most older patients use removable dentures, and the need for these dentures increases every year. Improving oral hygiene and denture hygiene is required in 42% to 76% of cases. Maintaining good oral hygiene is the prevention of various dental diseases and the long-term preservation of dental treatment results.
The review aimed to examine the status of the issue on methods of disinfection of removable dentures (partial and complete) at home.
A literature search was conducted on methods of disinfection of complete and partial removable dentures using Scopus, PubMed, Web of Science, eLibrary, and disserCat.
Search criteria: review articles, scientific articles and patents (in Russian or English), published no earlier than 2013, by keywords: removable dentures, oral microbiota of patients with removable dentures, hygiene of removable dentures, denture stomatitis and methods of hygienic treatment of dentures.
A total of 218 articles were studied. After a full-text analysis, 30 papers that met the search criteria were selected.
The use of toothpaste for cleaning dentures has been studied in 17% of scientific studies (n=5). The use of special disinfectant solutions was investigated in 53% (n=16). Approximately 20% (n=6) of the literature reviewed methods for disinfecting dentures using special devices. Methods of covering dentures with protective varnish were described in 10% (n=3) of the articles.
Existing methods for home denture care show a wide range of effectiveness, often with contradictory data. The selection of adequate methods of denture hygiene at home is an important issue that requires further study.

In our previous work, we suggested that analogs of mammalian kisspeptin Kiss1 reduce anxiety and phobic reactions novel in Danio rerio. The most effective dose for the action of the studied analogs of kisspeptin corresponded to 0.1 mg per 1000 mL of water. In this study, other analogs of mammalian Kiss1 at a dose of 0.1 mg per 1000 mL of water also reduced the anxious behavior of Danio fish. The effect of Kiss1 and Kiss2 kisspeptins on the behavior of Danio rerio was also evaluated. In the novel test, the number of freezing decreased by two times with the introduction of kisspeptin 10 and by three times after the introduction of the kisspeptin analog. An analog of mammalian kisspeptin reduced the freezing time by two times. The length of the trajectory decreased by two times under the influence of the mammalian Kiss1 kisspeptin analog. With the action of kisspeptin 10, the number of transitions to the upper part of the tank increased by two times. After the introduction of the kisspeptin analog, the number of transitions to the upper part of the aquarium increased by three times. In the predator test, the number and time of freezing decreased by 1.5 times with the action of mammalian kisspeptins. The length of the trajectory after the introduction of kisspeptin bony fish and kisspeptin 10 mammals increased. The length of the trajectory after the introduction of Kiss1 increased by 1.5 times. The length of the trajectory after the introduction of Kiss2 increased by three times. After the introduction of kisspeptin 10, the trajectory increased by two times, and the time spent in the lower part of the tank decreased by two times. Kisspeptins of bony fish also reduced the anxiety and phobic reactions in fish, but to a lesser extent. Thus, kisspeptin 10 and an analog of mammalian kisspeptin in response to the presentation of a predator had more significant effects on anxiety in Danio rerio compared with the action of kisspeptin bony fish Kiss1 and Kiss2. Thus, bony fish kisspeptins and mammalian kisspeptins can reduce anxiety and phobic reactions in Danio rerio; however, mammalian kisspeptins are the most effective. Bony fish kisspeptin Kiss1 has an anxiolytic effect in contrast to Kiss2, which suggests that it affects fear reduction, and Kiss2 appears to be responsible for social and sexual behavior. The results support the hypothesis that kisspeptins may be involved in the regulation of anxiety and phobic states, apparently to maintain the emotional aspects of reproductive behavior, such as sexual motivation and arousal.
Influence of oxytocin on the central nervous system by different routes of administration
Authors: Litvinova Maria V. , Tissen Llya Yu. , Lebedev Andrei A. , Bychkov Evgenii R. , Karpova Inessa V. , Shabanov Petr D.
Published: July 2023

BACKGROUND: One of the unresolved problems in improving the pharmacotherapy of central nervous system diseases is the development and creation of technologies that allow drugs to cross the bloodbrain barrier. One way to bypass the bloodbrain barrier is the intranasal route of administration. Drug delivery is influenced by the peculiarities of the mechanism of transport of substances.
AIM: To examine the effect of intranasal administration of oxytocin on the behavior of mice and its content in various brain structures.
MATERIALS AND METHODS: The study used 60 outbred mice divided into six groups. Group 1 were healthy and did not receive oxytocin or physiological solution, groups 2 and 3 received single injection of 20 and 300 L of oxytocin 5 IU intraperitoneally, respectively, group 4 was injected intranasally with 20 L of oxytocin 5 IU, group 5 received 20 L of saline intranasally, and group 6 received 300 L of saline intraperitoneally. Behavioral effects were recorded in the elevated plus maze for 5 min, and the duration of stay in the open arm, number of transitions between the arms, and number of hangings from the arms were assessed. The concentration of oxytocin was measured in the following structures: olfactory bulb, striatum, hypothalamus, and hippocampus using an enzyme immunoassay.
RESULTS: Intranasal administration of oxytocin causes changes in behavior in mice, particularly a decrease in the degree of anxiety (anxiolytic effect). When timing the open arms in the plus maze test, mice administered intranasal oxytocin spent more time in the arms (32.44 4.28 versus the control group with 5.66 1.96 s), the number of transitions between the sleeves increased (1.90 0.10 s versus 1.10 0.10 s in the control group), and number of hangings from the sleeves increased (8.44 1.37 versus 3.77 0.98 in the control group). An increase was noted in one of the indicators number of hangings from the sleeve after intraperitoneal injection of 300 L of oxytocin, which may indicate the anxiolytic effect of oxytocin. The remaining groups receiving intranasal saline injection, intraperitoneal saline injection, and intraperitoneal injection of 20 L of oxytocin did not show significant changes in behavior compared with the control group. In addition, after intranasal administration of oxytocin, its content increased in certain brain structures, i.e., the hypothalamus and hippocampus.
CONCLUSION: The results of this study indicate the potential efficacy of intranasal administration of oxytocin in the treatment of diseases affecting the central nervous system.

BACKGROUND: Mining grate prickly (Orostachys spinosa (L.) Sweet) is a perennial herb of the Crassulaceae family that is widely used in folk medicine fresh as a decoction for epilepsy and sedative for nervous disorders.
AIM: To examine the effect of O. spinosa dry extract on the white rat behavior in tests with positive reinforcement.
MATERIALS AND METHODS: Experiments were conducted on 82 Wistar rats. The O. spinosa dry extract effects at doses of 50, 100, and 200 mg/kg on animal behavior were assessed in the hypophagy and T-maze tests.
RESULTS: Following the introduction of O. spinosa extract at doses of 100 and 200 mg/kg, the number of animals fed in the hypophagy test was 1.6 and 1.8 times greater than that in the control, and the feed volume exceeded by 94% and 78%, respectively, the indicator in the control group. On day 4 of training, a conditioned reflex was observed in 100% of the animals treated with 200 mg/kg O. spinosa extract. Following the administration of the O. spinosa extract at a dose of 100 mg/kg and the reference drug, a conditioned reflex was observed in 63% and 71% of the animals, respectively, which was 2.0 times higher than that in the control group.
CONCLUSION: The 100 and 200 mg/kg O. spinosa dry extracts positively affected the removal of the anxiety level, promoted an increase in orientingexploratory activity, and thereby accelerated the development of a conditioned reflex in white rats.

OBJECTIVE: The aim of this study was to investigate the changes of the functionality, mood and life quality of patients diagnosed with hemiplegia due to an ischemic or hemorrhagic stroke during the COVID-19 pandemic.
MATERIAL AND METHODS: A total of 83 patients (mean age, 62.0±6.43 years) diagnosed with hemiplegia due to stroke, who received 30 sessions of rehabilitation therapy, before the COVID-19 pandemic, were included in this study. Data regarding the participants’ age, gender, body mass index (BMI), duration of stroke, stroke type, affected side, and education level were recorded. All the assessments were undertaken before the COVID-19 pandemic and repeated at the first year after the beginning of the pandemic. The functional status of the patients was evaluated with the Functional Independence Measure (FIM). The depression levels of the participants were evaluated using the Beck Depression Inventory (BDI). The life quality of the participants was evaluated using the Stroke-Specific Quality of Life Scale (SS-QOL).
RESULTS: There were significant differences in the FIM total scores of the patients evaluated before and during COVID-19 (91.32±15.94 and 87.15±15.60, respectively, p<0.001).When the FIM domain scores were evaluated before COVID-19 and at the first-year control during COVID-19, the FIM self-care scores were 27.45±6.62 and 25.27±7.08, respectively, the FIM sphincter control scores were 10.10±2.56 and 9.39±2.87, respectively, the FIM transfers scores were 14.67±3.36 and 13.61±3.54, respectively, the FIM social cognition scores were 18.40±1.86 and 17.67±1.93 respectively (p<0.001). The BDI score was 10.06±3.18 before the pandemic and 13.66±3.04 at the first year of the pandemic, the SS-QOL scores was 136.48±29.63 before the pandemic and 133.63±29.63 at the first year evaluation (p<0.001).
CONCLUSIONS: The COVID-19 pandemic has caused delays in both follow-up and rehabilitation therapy in patients with chronic hemiplegia. The functionality, life quality and mood of the patients have been affected due to the lack of therapy and social isolation.

Authors: Ünsal Pelin , Özdemir Sonay , Eroğlu Bayrak Nazlı Hilal
Published: July 2023

OBJECTIVE: The key component of preventive health care is adult immunization. The aim of this study was to assess the patients’ knowledge about adult vaccination and the vaccination rates of patients admitted to the family medicine outpatient clinics.
MATERIAL AND METHODS: A total of 442 patients were included in the study. Patient demographic and clinic characteristics were evaluated. Patients' vaccination status with influenza, pneumococcal vaccine, herpes zoster, and tetanus and their knowledge levels about adult vaccines were questioned.
RESULTS: The median age of the patients was 42 (min-max: 18-97) and 227 (51.4%) of them were female. Vaccination rates were found 32.6% for tetanus, 21.7% for influenza, 3.6% for pneumococcal, and 2.5% for herpes zoster. Patients with co-morbidities vaccination rates were found to be very low. The pneumococcal vaccination rate was 2.8%, the tetanus vaccination rate was 19.7% , and the influenza vaccination rate was 33.8% in geriatric patients. No patient older than 65 has ever received the zona vaccination. The rate of patients who had herpes zoster, pneumococcal vaccine, and tetanus vaccine was higher among university graduates. Fear of side effects (20%), difficulty in accessing the vaccine (6%), high vaccination prices (1%) were among the reasons why patients did not have vaccinated, and 16% of the patients stated that they did not believe in the benefits of vaccine.
CONCLUSIONS: In conclusion, we are still far below the desired levels of adult vaccination in our study population, and it is important to increase patients awareness of adult immunizations.
Hijrah and changing religious preferences in contemporary Islamic legal practice
Authors: Mustofa Imam , Juliansyahzen Muhammad Iqbal , Hefni Wildani
Published: July 2023

This research examines how urban Muslim communities in Purwokerto understand and practice religion in the area of muamalah (social relationships between people). Religious practice in urban Muslim communities is different from other religious communities. The intersection between the reality of modernity, Islamicity, and identity provides a model for distinguishing contemporary Muslim religious practices. This study is based on field research employing a phenomenological approach. Participatory observation was used to collect data from two mosques in Purwokerto City: the General Soedirman Grand Mosque and the Gelora Indah Mosque. Both mosques serve as the hub of religious discourse for Purwokerto's urban Muslim community, and they host a variety of religious studies on a regular basis. In-depth interviews were performed with worshippers from the two mosques by the researchers. Secondary data is derived from studies, journals, books, and other sources. This article concludes that urban Muslim identity is manifested in the shift away from usury practices and the choice of halal products. Studies in urban mosques and social media cannot isolate the rhetoric from the social formation of urban Muslims. In this environment, hijrah (shifting paradigm) has emerged as one of the trends that give rise to new nuances and views of any Islamic legal concept that is an annotated version of older works. Because of these shifts in preferences, the discipline of Islamic law, particularly fiqh muamalah, has become one of the most important areas for the expression of religious experience in the lives of urban Muslims

The Impact of the Covid-19 Pandemic on Financial Markets: A Metaanalysis From a Global Perspective
Authors: Fisnik Morina , Qlirim Gajraku
Published: July 2023

This study aims to examine the impact of the COVID19 pandemic on international financial markets in developed and developing countries. We have applied the approach of metaanalysis, meta-regression, critical analysis and the case study analysis. The empirical results of the meta-analysis show that the COVID-19 pandemic has affected the financial markets of developed countries through reduced supply, reduced demand, and economic instability. On the other hand, in developing countries, three indicators impact the international financial markets during the COVID-19 pandemic, such as confidence, expectations and changes in the consumption model. According to the results of the meta-regression, it is concluded that new daily cases of COVID-19 and deaths have negatively affected the daily returns of financial markets globally. The case study answers the research question of whether gold is a good hedge for stock portfolios during the COVID-19 pandemic. The findings of this study present several policy implications for governments around the world to adopt early proactive strategies and measures to control and protect international financial markets from a negative downturn in future economic recessions that pandemics may cause and to increase investor confidence.
