Formulation and Evaluation of Topical Microsponge Based Gel of Clotrimazole
Authors: Shinde Jitendra , Patel Rakesh , Shriwas Shweta
Published: October 2023

The study's overarching goal is to develop a novel medication delivery method based on microsponge gel containing clotrimazole. Clotrimazole is poorly absorbed from the gastrointestinal tract (GIT), has a short half-life of only 2 h, & is metabolized into inert molecules by the liver. Therefore, clotrimazole's drug delivery method must be modified for topical application. Microsponge delivery is a novel approach to sustained drug release. Microsponges were made with a polymer solution of Eudragit RS 100 in dichloromethane (DCM) and ethanol (1:1) using a quasi-emulsion solvent diffusion technique. A number of metrics, including production yield, entrapment efficiency, particle size measurement, and in vitro drug release studies, were used to each microsponge formulation. For topical administration, the optimized microsponge formulation F6 was transformed into a gel formulation. Prepared gel was compared to a commercially available formulation based on physical factors such as pH, viscosity, spreadability, drug content, and an in vitro diffusion investigation. Most of the formulations were discrete and spherical in shape, indicating a satisfactory production yield, suggesting quasi-emulsion solvent diffusion method is a promising methodology for the fabrication of microsponge. Clotrimazole was released steadily over the course of 12 hours from the microsponge gel formulation MGI (F6). Therefore, the medicine in the form of a microsponge can reduce the risk of adverse effects and increase patient compliance by avoiding skin contact.

An important goal of early childhood education is teaching emotional self-regulation within the context of a safe, stable, nurturing environment. Expulsion of young children ignores underlying emotional and behavioral concerns, disproportionately affects children of color (Black or Hispanic), males, children with disabilities, and socioeconomically disadvantaged populations, and has long-term consequences on educational and life success. Addressing implicit bias and providing child mental health consultation (psychologists, social workers, developmental behavioral pediatricians, child psychiatrists, and child neurologists) to child care providers can prevent expulsion. Pediatricians and other providers within the medical home play an important part in preventing expulsion. However, pediatricians need more training in early childhood mental health and in understanding how systemic racism and implicit bias lead to preschool expulsion in children of color. By identifying children at risk for expulsion because of poverty, racial discrimination, toxic stress, insecure attachment, or history of trauma, the pediatrician can connect families with community resources that may ameliorate these effects. Pediatricians can provide information on social-emotional development in early childhood, promote positive parent-child relationships, and model and discuss age-appropriate and developmentally appropriate behavior management. Pediatricians can also guide parents toward high-quality child care programs that use mental health consultation and developmentally appropriate activities, both of which lessen the chance of child expulsion. Furthermore, behavioral health providers integrated into the medical home can provide consultation to child care providers on managing patients. These recommendations are consistent with our knowledge of early child brain development and support the current tenets of the American Academy of Pediatrics regarding the pediatrician’s role in building resilience and buffering toxic stress to promote optimal child development.
Optimizing culture conditions of human umbilical cord mesenchymal stem cells (hUC-MSCs) by adjusting the volume of xeno-free supplement serum

Published: October 2023

Mesenchymal stem cells (MSCs) have become an effective tool for treating immune-related diseases due to their multilineage potential and immunomodulatory capabilities. However, a high cell dose is frequently essential for stem cell infusion in clinical practice. Therefore, it is necessary to produce sufficient quantities of MSCs while ensuring cell quality for clinical application in humans. To be able to use stem cells in patients requires a more rigorous captive procedure than using a xeno-free medium that does not contain substances derived from the hypothetical allergenic regime. Therefore, current cell culture procedures substitute xeno-free culture media with added supplement serum for the traditional DMEM media with bovine fetal serum (FBS). This switch increased the production cost immensely and made it difficult to produce MSCs on an industrial scale. In this study, we optimized the condition of MSCs’ cultures by adjusting the amount of the supplement serum usage to reduce production costs for industrial manufacturing. This is the first study to claim that reducing the amount of xeno-free supplement serum had no effect on the quality of hUC-MSCs isolated from Vietnamese children’s umbilical cords.

Published: October 2023

OBJECTIVES The purpose of this study was to compare the effects of 12-week online-delivered isometric and dynamic core stability exercises on functional movements, dynamic postural control, and core endurance in healthy young adults.METHODS This is a single-blind randomized controlled trial. Sixty young adults (age range: 19-34 years; 12 males, 48 females) participated in this study. They were randomly assigned to the isometric core exercise [ICE], dynamic core exercise [DCE], or control group. Participants in the ICE and DCE groups performed 40-60 min real-time online-delivered core exercise session via Zoom video conferencing application, twice a week for 12 weeks. Participants in the control group did not participate in exercise intervention. All participants were asked not to participate in other exercises for 12 weeks. The outcome measurements include the functional movement screen, Y-balance test (upper & lower), and core endurance tests (flexor, extensor, and lateral flexor of the trunk).RESULTS The results of this study showed significant improvement in core endurance, functional movement, and dynamic postural control of the upper body in the ICT and DCE groups compared with the control group. However, significant differences were not found between the ICE and DCE groups in all variables.CONCLUSIONS Both types of online-delivered core exercise programs have been shown to be effective in improving functional movement, dynamic posture control, and core endurance in young adults. In addition, since both types of exercise have been shown to be effective on core stability related variables, both types of exercise can be recommended for young adults. However, further studies are warranted to investigate the gender differences on the effects of the core stability exercises.
MESAS-REDONDAS SOBRE FUTEBOL NA TELEVISÃO: UMA ANÁLISE DO ETHOS DISCURSIVO
Authors: Khalil Lucas Martins Gama
Published: October 2023

Resumo Este artigo estuda o funcionamento discursivo de mesas-redondas sobre futebol em programas esportivos televisivos. O estudo parte da hipótese de que a legitimidade dos argumentos nesses debates depende, em grande parte, da encenação da imagem dos enunciadores (mediador e comentaristas) por meio da maneira como estes enunciam. Há desde os programas nos quais os comentaristas negam o “clubismo” em nome da “neutralidade” jornalística até programas em que comentaristas se apresentam ao público como “representantes” dos times. Tratando-se de uma pesquisa fundamentada na Análise do Discurso, o trabalho não objetiva prescrever os rumos “adequados” do debate futebolístico, mas verifica como determinados sentidos são validados nesses discursos. Recorrendo-se à teorização de Charaudeau relacionada ao ato de linguagem como encenação e buscando apoio em estudos de Maingueneau e Amossy quanto à noção de ethos, analisam-se os programas Jogo Aberto (Rede Bandeirantes) e Linha de Passe (ESPN Brasil).
MATÉRIA ESCURA DA METÁFORA: O QUE A METAFORICIDADE DIZ A RESPEITO DA MENTE
Authors: Dienstbach Dalby
Published: October 2023

Resumo Em sentido lato, este trabalho explora a possibilidade do processamento consciente de metáforas. Especificamente, ele tem o objetivo de investigar em quais circunstâncias expressões metafóricas usadas no discurso podem ser desautomatizadas (Kyratzis, 2003) ‒ ou seja, podem ser reconhecidas como sendo metáforas ‒, bem como quais elementos (do discurso) seriam responsáveis por essa desautomatização. Lançando mão dos conceitos de metáfora conceptual (Lakoff; Johnson, 2002 [1980]) e de metaforicidade (Müller, 2008), este trabalho identifica e analisa a coocorrência e o funcionamento de recursos de metaforicidade (Müller, 2008) em exemplos concretos de uso de metáforas, no esforço de compreender e de explicar como esse uso poderia ser posto à luz da nossa consciência. Esta discussão mostra, em última análise, que diferentes elementos cotextuais ‒ tais como advérbios e conjunções particulares, além de imagens ‒ seriam capazes de viabilizar o reconhecimento de expressões metafóricas como sendo metáforas no discurso.

Published: October 2023

RESUMO O manuscrito se propõe a uma análise crítica da possibilidade do psicanalista na instituição escolar. Valendo-se da Psicanálise aplicada associada à pesquisa bibliográfica e a fragmentos de lembranças provenientes da prática no cotidiano escolar como eixo condutor, compreende-se a posição do psicanalista na instituição como aquela que visa à promoção do sujeito. Investigam-se sites de três sistemas de ensino em destaque no Brasil hoje. Localiza-se o significante desempenho vinculado à promessa de ingresso na universidade proveniente do uso do material didático de cada um deles. Percorre-se a teoria dos discursos de Lacan demonstrando os discursos capitalista, mestre contemporâneo e universitário como predominantes na escola atual. O psicanalista, ao operar com o discurso do analista em sua escuta, permite o bem dizer do sujeito, exercendo, assim, a função de desalienistas. Essa função se alicerça num distanciamento das identificações imaginárias e totalizantes, que expressam o sistema de ensino em nosso País.
EDUCATIONAL TEACHING SYSTEMS: DISCIPLINE REQUIREMENTS AND STUDENT’S PERFORMANCE FROM A PSYCHOANALYTICAL PERSPECTIVE
Authors: Simões Marina Silva , Kyrillos Neto Fuad , Calzavara Maria Gláucia Pires
Published: October 2023

ABSTRACT The manuscript proposes a critical analysis of the possibility of the psychoanalyst in the school institution. Taking advantage of Applied Psychoanalysis associated with bibliographical research and memories fragments from daily practice at school as a guiding axis, the psychoanalyst’s position in the institution is understood as that which aims at the promotion of the subject. Sites of three education systems highlighted in Brazil today are investigated. The significant performance linked to the promise of enrolling the university resulting from the use of the didactic material of each one of them is located. Lacan’s discourses theory is covered, demonstrating the capitalist, contemporary teacher and university discourses as predominant in current school. The psychoanalyst, when operating with the analyst’s discourse in his listening, allows the subject to say well, thus exercising the function of disalienists. This function is based on a distancing from the imaginary and totalizing identifications that express the education system in our country.
A spurious elevation of serum creatinine level in a patient with Crohn’s disease without histologic kidney damage: a case report and review of the literature
Authors: Lee Sul A , McMahon Gearoid Michael
Published: October 2023

ABSTRACT Patients with inflammatory bowel disease (IBD) are prone to develop kidney injury. Renal involvement in IBD patients is usually diagnosed by the measurement of serum creatinine and the estimation of the glomerular filtration rate. We describe a patient with IBD who presented with large fluctuations in his serum creatinine level (~3.0-fold) without significant histologic abnormalities and with a normal cystatin C level. This appears to be related to a high-protein diet and intermittent fasting. Even though the impact of a high-protein diet on mild elevations of the serum creatinine level has been described, large fluctuations in serum creatinine from diet alone, as seen in this case, have never been reported, raising the question about the potential contribution of inflamed bowel on gut absorption or metabolism of creatinine. This case highlights the importance of a detailed history, including the dietary habits, when encountering a patient with increased serum creatinine level, and careful interpretation of serum creatinine in a patient with a creatinine high-protein diet or underlying IBD.

Abstract Introduction Patient and public involvement has numerous benefits for research; however, there are challenges to its implementation, such as the lack of tools to guide participant engagement in research. The Involvement Matrix (IM) is a tool that facilitates discussion about the role that participants play in research projects, promoting more active public involvement. Objective To translate IM materials into Brazilian Portuguese in order to facilitate their use and guide researchers. Methods Authorization to translate the original material into Brazilian Portuguese was obtained from the authors. Next, the translated material underwent backtranslation. The resulting version was verified by the original IM authors, ensuring semantic and content accuracy. Results The Involvement Matrix (IM) was translated into Portuguese and then backtranslated into English. The researchers discussed the translated version with the IM authors, with minimal adjustments needed in the backtranslation, and no changes made to the Portuguese version. After the approval of the final Brazilian Portuguese version, the translated tools were made available, including a Practical Guide, a Word Version, a Checklist, a Fact Sheet, an Overview with Examples, and an Animated Video with Brazilian Portuguese subtitles. Conclusion The various IM materials are adequately translated and freely available for use in Brazil. It is a valuable tool to guide public and patient involvement in research.

Abstract: Aim Paracetamol (PCM), or acetaminophen, is one of the most used drugs for human treatment of pain and fever. Since it has often been found in the aquatic environment, the aim of this study was to investigate the effects of PCM on the reproductive axis of male Rhamdia quelen catfish. Methods Different biomarkers were evaluated in hypothalamus, liver and gonads, as well as the plasma sexual hormone quantification. The fish were exposed to three PCM concentrations: 0.25, 2.5 and 25 µg.L-1 and to a control group (solvent acetone 0.0003%). After 14 days of exposure, fish were anesthetized, for blood sampling and biometrics, and after euthanasia, the tissues were sampled. Plasma was used for 11- keto testosterone and 17β - estradiol quantification. The hypothalamus was collected for brain aromatase (cyp19a1b) gene expression; the liver for the vitellogenin (vtg) gene expression and biochemical biomarkers; and gonad for the biochemical and histological biomarkers analyses. Results No alterations were observed in the hormone’s levels, sexual maturation level or in cyp19a1b and vtg gene expression. In the liver the non-protein thiols concentration increased at 2.5 µg.L-1 of PCM, and the superoxide dismutase (SOD) activity was reduced at 0.25 µg.L-1 of PCM. In gonads, glutathione S-transferase (GST) activity decreased and SOD activity increased at 25 µg.L-1 of PCM, while the glutathione peroxidase (GPx) activity reduced after exposure to both PCM concentrations. Conclusion The results showed that environmental concentrations of PCM can cause alterations in the antioxidant system, mainly in the gonads of R. quelen males. However, without significant change in the hormones levels or in the expression of genes related to the reproduction axis. These alterations occurred at concentrations already found in aquatic environment, including in Brazil.

Shaking table test on seismic responses of asymmetrical underground subway stations
Authors: Wang Guobo , Wang Yao , Wang Jianning , Dong Zhengfang
Published: October 2023

Currently, many subway stations are designed symmetrically and less attention has been paid to asymmetrical stations. The middle column of the asymmetric underground structure is offset to one side, which is not conducive to load bearing during strong earthquakes and is prone to damage. In this study, shaking table tests of a soil-symmetrical station and a soil-asymmetrical station were designed and conducted. A numerical model of the soil–structure interaction system was established, and the feasibility of the simulation method was verified. Then, the seismic responses of two kinds of stations were discussed and analysed. The results show that the dynamic response of both symmetrical and asymmetrical stations increases with the increase of the loading seismic intensity. Influenced by the size effect of the model test, there is less difference between the two models in their dynamic response. From the perspective of internal force and relative deformation, the response of the asymmetrical station is greater than that of the symmetrical station, which adequately reflects the disadvantage of asymmetrical structures in seismic design.

O presente estudo analisa o projeto de Saneamento Urbano Integrado de Aceguá, na fronteira entre o Brasil e o Uruguai, financiado pelo Fundo de Convergência Estrutural do MERCOSUL, concebendo o próprio FOCEM como uma política pública regional em escala macro. Por meio da documentação indireta e utilizando fontes primárias, secundárias, bibliográficas e jornalísticas, os resultados encontrados permitiram concluir que houve entraves administrativos e ambientais na execução das obras do projeto no lado brasileiro, enquanto a porção uruguaia se desenrolou dentro do prazo previsto e foi inaugurada sem que se concluísse o projeto binacional como um todo. A partir de um exame dos motivos para o atraso das obras no Brasil, o estudo sugere algumas possibilidades para aprimorar os mecanismos institucionais do FOCEM como política pública em escala regional, aperfeiçoando a transparência e acelerando assim os resultados dos projetos fomentados.
Assessment of small business development level in resource regions of Russia
Authors:   Kemerovo State University, Korchagina Irina V.
Published: October 2023

Introduction: small business may be important for a more balanced development of Russian resource-type regions, but its current state has not been sufficiently studied. Aims: to determine of the state and features of the small business development in the regions of the resource type. Methods: descriptive statistics, Wilcoxon’s t-test, Student’s t-test, cluster analysis. Results: it is shown that the “resource curse” is generally not typical for the small business development in Russia, but the growth rate of small businesses turnover (adjusted for inflation) and their number in resource regions is below the national average. This is because in the resource regions, types of activities, where small businesses are dominant, are less represented. The specific indicators of small enterprises labor productivity and per capita turnover in resource-type regions are lower than the average for the country and the corresponding federal districts. At the same time, investments per small business enterprise are higher. Small business enterprises development indicators in the regions correlate to a small extent. There are different regional models for the development of small businesses, depending on their geographical location, climatic conditions, demographic trends, and economic situation. Conclusions: in the resource type regions, small business develops more slowly than in the country as a whole; it is less efficient in terms of labor productivity but receives more investment.

Introduction: in the context of the emerging transition to the sixth technological wave and to implement the government’s goals for the country’s technological development, it is necessary to develop a holistic concept for the formation of an effective technologies’ portfolio at any level of decision-making – from national to corporate. An important role in this belongs to the process of assessment and selection of technologies, which, to be built on a scientific basis with the use of adequate tools, determines the relevance of the research. Aims: to develop a conceptual and systematizing model of instrumental support for the implementation of the technology assessment and selection process, that will make it possible, while considering the characteristic features of each stage of this process, to form a holistic vision of effective ways to improve its effectiveness based on a set of applied tools. Methods: system and logical analysis, structuring, grouping, graphical, algorithmic, matrix and criteria methods. Results: a conceptual and systematizing model of instrumental support for the implementation of the technology assessment and selection process is proposed. This model consists of the following four successive stages: technology maturity assessment, criteria system formation, technology assessment and technology selection. For each stage of the process, recommendations are formulated on the use of specific methods and tools. As the study showed, only methods and tools for technology maturity assessment have been deeply methodologically studied and in the current situation are widely used in practice, while the subsequent stages of decision-making are methodologically studied very superficially. Conclusions: the approach justified by the authors to the implementation of the end-to-end process of technology assessment and selection will provides a consistent solution to interrelated tasks of identifying opportunities and constraints of new technologies at different levels of decision-making. The use of the results of this study is seen in the further expansion of methodological research in the context of the emerging concept of technology assessment, moving from the outdated practice of applying a single universal approach using numerical indicators to cross-examination and communicative interaction of different points of view to determine the potential capabilities of technologies.

Objetivo: Evaluar la eficiencia de los métodos de fumigación contra la Sigatoka Negra en plantaciones de banano que aporte al desarrollo territorial sostenible en el departamento del Magdalena, Colombia. Metodología: Se utilizó la metodología del proceso analítico jerárquico (AHP) considerando cinco criterios: costo, cobertura, impacto ambiental, eficacia y precisión, seguridad y salud. Se consultó a cuatro expertos en las siguientes áreas: Fitopatólogo, agricultor, administrador de finca, especialista en salud pública y ambiental, para obtener su opinión sobre la importancia de cada uno de los criterios e identificar cada método de fumigación en relación con estos. Resultados: Se establece un listado jerárquico de los métodos de fumigación, basado en los criterios anteriormente descritos, identificando que el dron es el método de fumigación ideal para cumplir el objetivo con 62,41%, seguido de los equipos manuales con 21,45%, por último, la fumigación con avioneta con 16,14%. Asimismo, se identificó que el costo no es un criterio relevante en la fumigación, comparado con la salud de los campesinos, el impacto ambiental y la efectividad. Conclusiones: La metodología AHP es válida para identificar el listado jerárquico de los métodos de fumigación, permitiendo con este trabajo justificar la decisión para seleccionar el más adecuado y conocer la importancia de cada criterio en dicha selección. Además, se recomienda el uso del dron como método de fumigación para el control de la Sigatoka Negra en plantaciones de banano, ya que, es el método más efectivo y sostenible en términos de impacto ambiental, seguridad y salud de las personas.
El derecho humano a la paz: contenido, retos y formas de concreción
Authors: Arrieta López Milton
Published: October 2023

El presente trabajo tiene por objeto analizar la perspectiva de la materialización de la paz como un derecho humano de la solidaridad o de tercera generación. Se realizó una investigación cualitativa y de corte bibliográfico documental, la cual permitió la búsqueda, el estudio y la interpretación de la información con el propósito de construir conocimiento a través del análisis crítico. Entre los hallazgos conseguidos se encontró como principal obstáculo para la concreción del derecho humano a la paz la falta de apoyo de algunos Estados desarrollados liderados por Estados Unidos, Reino Unido y Francia, su naturaleza dual de titularidad y la necesidad de construir una educación para la paz. Se concluye principalmente que no existe la posibilidad de concretizar ningún derecho humano en estado de violencia, por ende, solo mediante la concreción del derecho humano a la paz se podrán tutelar y exigir todos los derechos humanos. También se concluye que se necesita un cambio estructural en el orden económico que impera en el mundo capaz de eliminar la pobreza, las desigualdades y la exclusión, por considerar a éstas como las causantes de la violencia estructural la cual imposibilita a la paz positiva en todas sus dimensiones.

Study purpose. The assessment tools or skills tests, such as the AAHPERD basketball skill test and the Johnson basketball test, are all partial or separate. All these tests are old products, while the game of basketball is constantly evolving. The purpose of this study was to design and validate basketball skills and performance tests for players aged 14–16 years to shorten the test time, shorten the waiting time for results, and be comprehensive so that they can reflect real abilities and can be used as a reference when carrying out selection and evaluation.
Materials and methods. A total of 7 experts assessed the 11 elements (86 items) of the basketball skill and performance test (BSPT). Three academic experts and four basketball coach experts took part in the study. Data was collected using the Delphi technique and test-retest, and data was analyzed using Aiken’s formula, intraclass correlation coefficients (ICC), and Cronbach’s alpha.
Results. With a value of 0.91, the expert assessment tool shows that the content validity of the aspect is good. Cronbach’s alpha was used to measure the reliability of every aspect of the basketball skill and performance test instrument, and the results were 0.918. The result of the ICC score agreement between raters is 0.912, while for one rater, the consistency is 0.596.
Conclusions. The implications of this study could prove that the BSPT can be used to assess the skill level of adolescent basketball players, benefiting not only basketball coaches but also physical education teachers.

Okra is known for its neuroprotective and antioxidant properties. We aimed to investigate the potential effects of okra seed powder in alleviating high far diet (HFD) induced cognitive deficit and hypercholesterolemia. We randomly allocated thirty-six C57BL/6J male mice into: (i) control, mice fed with a normal fat level diet; (ii) HFD, mice fed with HFD; (iii) HFD-OS1; (iv) HFD-OS2; (v) HFD-OS3, mice fed with HFD and okra seed powder (200, 400, or 800 mg/kg/day, respectively); (vi) HFD-SIM, mice fed with HFD and simvastatin (20 mg/kg/day). After 10 weeks of treatment period, the mice were tested with an episodic-like memory test (EMT) and Morris water maze (MWM). We found significantly higher total and LDL cholesterol levels in mice fed with HFD. Compared to the HFD group, the control group performed better in the EMT test, and also learned and retrieved spatial reference memory better in the MWM test. The okra seed powder significantly improved spatial learning in four days of acquisition trials and the highest dose of okra profoundly improved spatial reference memory retention during the probe trial. Contrary to the MWM results, the okra-treated animals did not perform significantly better than the HFD-treated animals in EMT. At present, we recommend future studies testing the potential neuroprotective or cognitive enhancing effects of okra to assess different cognitive domains using various disease models to have a better understanding on the potential neuroprotective properties of okra.

Lassa fever (LF) is endemic in West Africa and Nigeria in particular. Since 1969 when the disease was discovered, a seasonal outbreak is often reported in Nigeria. Many researchers have reported inconsistent or varying numbers of suspected, confirmed and death cases since 2012 to date. To enhance this reportage, and due to the high mortality rate associated with LF, it is pertinent to design a suitable and robust model that could predict or estimate the number of LF cases based on the onset data. To achieve these, we proposed a recursive prediction (RP) model that could do predictions with the onset data. The Pearson correlation coefficient (R) and R2 are applied to determine the performance analysis of the model. The RP model predicted 96.7% confirmed cases and 89.6% death cases for the first three months of 2022 based on the onset data. The model was also applied to predict COVID-19 death cases during the six weeks of the outbreak in India. The result showed a comparable prediction with the regression output for the COVID-19 death cases. This study demonstrated that the proposed model could be applied to perform prediction for any disease of unknown etiology during the onset of the disease outbreak without any treatment similar to the COVID-19 outbreak. The performance analysis of the RP showed that the model is useful to predict the increasing trend of an outbreak of a disease with unknown etiology without prior treatment experience and vaccines.
