Balance Sheet Rules and their Influence on Business Performance – An Empirical Study
Authors: Nosková Marta , Taušl Procházková Petra , Jelínková Eva
Published: October 2022

The study aims to examine in detail the impact of compliance with balance sheet rules on business performance. To examine this premise, data from small and micro businesses in the Czech Republic (total number 2,537) were statistically tested using t-test and Mann-Whitney U test. Particular attention was paid to the value of the return on equity indicator (as a business performance indicator), and the changes in this value between the business groups that comply and those that do not comply with these rules. The results suggest that the positive effect of balance sheet rule compliance on business performance cannot be confirmed, nor the predominant compliance among businesses was proven. Thus, the discussion of whether the balance sheet rules need regularly appear in the current business economics literature should be open. The results are presented and discussed in this paper, together with their limitations.

Published: October 2022

Primary hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome caused by impaired lymphocyte cytotoxicity. First‐line therapeutic regimens directed against activated immune cells or secreted cytokines show limited efficacy since they do not target the underlying immunological problem: defective lymphocyte cytotoxicity causing prolonged immune stimulation. A potential rescue strategy would be the adoptive transfer of ex vivo gene‐corrected autologous T cells. However, transfusion of cytotoxicity‐competent T cells under conditions of hyperinflammation may cause more harm than benefit. As a proof‐of‐concept for adoptive T cell therapy (ATCT) under hyperinflammatory conditions, we transferred syngeneic, cytotoxicity‐competent T cells into mice with virally triggered active primary HLH. ATCT with functional syngeneic trigger‐specific T cells cured Jinx mice from active HLH without life‐threatening side effects and protected Perforin‐deficient mice from lethal HLH progression by reconstituting cytotoxicity. Cured mice were protected long‐term from HLH relapses. A threshold frequency of transferred T cells with functional differentiation was identified as a predictive biomarker for long‐term survival. This study is the first proof‐of‐concept for ATCT in active HLH.

Las fajas de enriquecimiento (FE) y el tropical shelterwood modificado (TS) son sistemas silviculturales que buscan aumentar la productividad en un bosque natural. Este estudio evaluó la incidencia de ambos sistemas sobre el índice de área foliar (IAF) dentro del bosque natural. Las evaluaciones se realizaron en el 2018 en cuatro áreas: a) la primera, 4 ha (fajas de enriquecimiento); b) la segunda, 4 ha (tropical shelterwood modificado); c) la tercera, 3 ha (bosque no intervenido - primario – testigo – sector (A)); d) la cuarta, 3 ha (bosque intervenido – secundario – sector (BSI)). El índice de área foliar (IAF) fue estimado mediante fotografías hemisféricas (FH), en parcelas con tratamientos (sistemas silviculturales) y testigos. Por un lado, el tratamiento silvicultural con menor promedio de IAF fue el tropical shelterwood modificado (TSM, con un IAF = 1,27) siendo el caso contrario para el bosque primario no intervenido (BPNI, con un IAF = 2,75). Por otro lado, los valores para el sistema fajas de enriquecimiento (FE) y bosque secundario intervenido (BSI) fueron (IAF = 1,49 y IAF = 2,23) respectivamente.

OBJECTIVES

Acute gastroenteritis (AGE) outbreaks commonly occur in congregate settings, including schools and childcare facilities. These outbreaks disrupt institutions, causing absences and temporary facility closures. This study analyzed the epidemiology of school and childcare AGE outbreaks in the United States.

METHODS

We analyzed AGE outbreaks occurring in kindergarten to grade 12 schools and childcare facilities reported via the National Outbreak Reporting System in the United States from 2009 to 2019 and compared this information to 2020 data. Outbreak and case characteristics were compared using the Kruskal-Wallis rank sum test, χ2 goodness-of-fit test, and Fisher exact test.

RESULTS

From 2009 to 2019, there were 2623 school, 1972 childcare, and 38 school and childcare outbreaks. School outbreaks were larger (median, 29 cases) than childcare outbreaks (median, 10 cases). Childcare outbreaks were longer (median, 15 days) than school outbreaks (median, 9 days). Norovirus (2383 outbreaks; 110 190 illnesses) and Shigella spp. (756 outbreaks; 9123 illnesses) were the most reported etiologies. Norovirus was the leading etiology in schools; norovirus and Shigella spp. were dominant etiologies in childcare centers. Most (85.7%) outbreaks were spread via person-to-person contact. In 2020, 123 outbreaks were reported, 85% in the first quarter.

CONCLUSIONS

Schools and childcare centers are common AGE outbreak settings in the United States. Most outbreaks were caused by norovirus and Shigella spp. and spread via person-to-person transmission. Fewer outbreaks were reported in 2020 from the COVID-19 pandemic. Prevention and control efforts should focus on interrupting transmission, including environmental disinfection, proper handwashing, safe diapering, and exclusion of ill persons.

A tudomány tömegesedésének hatásai a felsőoktatás működésére
Authors: Király Gábor , Kováts Gergely
Published: October 2022

Jelen tanulmányban arra a kérdésre keressük a választ, hogy a tudomány expanziója milyen következményekkel jár a felsőoktatás működésére. Ennek megfelelően a tanulmány első, bevezető szakasza bemutatja, hogy milyen mennyiségi és minőségi változásokon ment keresztül a tudomány, valamint, hogy ez mennyiben változtatta meg a tudományos szféra belső szerveződését. Ezt követően az expanzió két hatását tárgyaljuk bővebben. Egyfelől bemutatjuk a kutatás funkcióinak differenciálódását és feszültségeit. Ebben a fogalmi keretben a kutatás hat különböző társadalmi szerepét különböztethetjük meg. Az ezek között kialakuló potenciális feszültségek egyik legjobb példája, hogy hogyan kerül egymással szembe az a kutatásfelfogás, amely ezt a tevékenységet mint az egyetemi, akadémiai szakma közös jellemzőjét fogja fel, valamint az, amely a teljesítmény mérésére és a kutatók rangsorolására helyezi a hangsúlyt. Ehhez a feszültségforráshoz kapcsolódik az expanzió másik fontos hatása, a „publish or perish” kultúra elterjedése és intézményesülése. A tanulmány lezáró részében a kutatás jövőjével kapcsolatos trendeket mutatunk be.
A közfoglalkoztatottaknak szóló képzések vizsgálata hazánkban (2016–2020)
Authors: Hajdú Dávid
Published: October 2022

A tanulmány az elsődleges munkaerőpiacról kikerült közfoglalkoztatottaknak szóló képzések főbb jellemzőit vizsgálja a 2016–2020 közötti időszakban, kitérve a résztvevők számának nem, korcsoport, iskolai végzettség szerinti megoszlására, valamint a későbbi sikeres munkaerőpiaci elhelyezkedésre is. A közfoglalkoztatás egy átmeneti állapot, amely arra hivatott, hogy a munka világából kiszorulókat visszasegítse a munka világába. A közfoglalkoztatottaknak szóló képzések ugyanezen cél mentén jöttek létre, hogy egy új szakma elsajátításával minél hamarabb munkához jussanak a képzéseken részt vevők. Az eredmények nagy területi, térségi különbségeket mutatnak, és kijelenthető, hogy azokba a térségekbe (főként a keleti régiókba) csoportosultak a képzések, ahol a legnagyobb szükség van rá. Ugyanakkor összességében elmondható, hogy a képzések nem érték el a kívánt eredményt, hiszen a képzést sikeresen elvégző közfoglalkoztatottak a képzés elvégzése után 6 hónappal vagy munkanélkülivé váltak, vagy csak a másodlagos munkaerőpiacon, azaz közfoglalkoztatottként tudtak csak újra elhelyezkedni.

Improving Connectivity: Innovative Fiber-Reinforced Polymer Structures for Wildlife, Bicyclists, and/or Pedestrians
Authors: Bell Matthew , Ament Rob , Fick Damon , Huijser Marcel
Published: October 2022

Engineers and ecologists continue to explore new methods and adapt existing techniques to improve highway mitigation measures that increase motorist safety and conserve wildlife species. Crossing structures, overpasses and underpasses, combined with fences, are some of the most highly effective mitigation measures employed around the world to reduce wildlife-vehicle collisions (WVCs) with large animals, increase motorist safety, and maintain habitat connectivity across transportation networks for many other types and sizes of wildlife. Published research on structural designs and materials for wildlife crossings is limited and suggests relatively little innovation has occurred. Wildlife crossing structures for large mammals are crucial for many highway mitigation strategies, so there is a need for new, resourceful, and innovative techniques to construct these structures. This report explored the promising application of fiber-reinforced polymers (FRPs) to a wildlife crossing using an overpass. The use of FRP composites has increased due to their high strength and light weight characteristics, long service life, and low maintenance costs. They are highly customizable in shape and geometry and the materials used (e.g., resins and fibers) in their manufacture. This project explored what is known about FRP bridge structures and what commercial materials are available in North America that can be adapted for use in a wildlife crossing using an overpass structure. A 12-mile section of US Highway 97 (US-97) in Siskiyou County, California was selected as the design location. Working with the California Department of Transportation (Caltrans) and California Department of Fish and Wildlife (CDFW), a site was selected for the FRP overpass design where it would help reduce WVCs and provide habitat connectivity. The benefits of a variety of FRP materials have been incorporated into the US-97 crossing design, including in the superstructure, concrete reinforcement, fencing, and light/sound barriers on the overpass. Working with Caltrans helped identify the challenges and limitations of using FRP materials for bridge construction in California. The design was used to evaluate the life cycle costs (LCCs) of using FRP materials for wildlife infrastructure compared to traditional materials (e.g., concrete, steel, and wood). The preliminary design of an FRP wildlife overpass at the US-97 site provides an example of a feasible, efficient, and constructible alternative to the use of conventional steel and concrete materials. The LCC analysis indicated the preliminary design using FRP materials could be more cost effective over a 100-year service life than ones using traditional materials.

ABSTRACT Objectives: to analyze the personal and work-related burden factors associated with physical and emotional symptoms of informal caregivers of the elderly. Methods: cross-sectional study conducted with 121 informal caregivers and 121 seniors who received care, assessed individually for the risk of: physical overload, musculoskeletal symptoms, Self-Reporting Questionnaire, effort perception, and Katz index. Results: a greater perception of effort raises up to 3.3 times the chances of presenting symptoms of pain in the spine region (p=0.01), and lower functional capacity of the elderly increases up to 1.3 times the chances of presenting pain symptoms in the spine region (p=0.02). The symptoms of emotional overload were associated with the caregiver’s low income (p=0.02). Conclusions: the perception of effort, dependence of the elderly, caregiver’s age, and symptoms of emotional overload are involved with caregivers’ symptoms of physical overload, and low income, with emotional overload.

RESUMO Objetivos: analisar o déficit do autocuidado entre homens idosos no curso da pandemia de COVID-19 no Brasil e discutir as implicações para a prática em enfermagem. Métodos: web survey, multicêntrica, qualitativa. Participaram 120 homens idosos, sob aplicação de formulário de abril a junho de 2020 e abril a agosto de 2021. Empregou-se a Análise Temática Reflexiva, interpretada pela Teoria do Déficit do Autocuidado de Orem. Resultados: temporalmente, o autocuidado de homens idosos se manifestou nos requisitos de autocuidado - vínculos afetivos, autocuidado para o desenvolvimento - meditação e autocuidado com desvios de saúde - consultas remotas. Déficits no autocuidado emergiram dos danos biopsicossociais. Os sistemas totalmente, parcialmente compensatórios, educativo/de apoio mobilizaram o autocuidado. Considerações Finais: como gestores do cuidado, enfermeiros podem fortalecer a rede de apoio aos homens idosos acionando profissionais da equipe multiprofissional, familiares, cuidadores e comunidade para promover autocuidado e corrigir desvios de saúde em momentos de crise.

ABSTRACT Objectives: to report the experience on the operationalization of a university extension project with and for training affirmative action students. Methods: an experience report with a descriptive approach on the operationalization of a university extension project for training affirmative action students, between 2020 and 2021, based on blended-learning and Activity Theory. Results: we carried out 103 activities, including actions for product development, media maintenance and targeted study of themes. They involved 13 students from two institutions, two leaders from ethnic groups and eight instructors. Final Considerations: collaborative relationships provided the exchange of knowledge about public health policies, educational technologies and social media, reducing deficits in the use of technological resources and application in health education. The activities promoted students’ leading role coming from affirmative action, in a representative way, from their experiences and needs, being potential for equitable training.

Published: October 2022

ABSTRACT Objectives: to discuss the applicability of the conceptual map and its underlying theoretical anchors and analyze the challenges and potentialities of this method concerning the participation of Indigenous Peoples. Methods: experience report of the use of the conceptual map as a data collection instrument. Results: the study allowed us to discuss the epistemic approaches and distances, as well as to analyze to what extent the conceptual map favored the process of joint production of knowledge with Indigenous Peoples. The experience with this type of research design also revealed epistemological challenges that reflect the established historical relationships, whose overcoming implies the construction of new forms of egalitarian and intercultural scientific relations. Final Considerations: the conceptual map theoretically composes a structured participatory methodology, which enables data collection and the collective construction of knowledge, provided that the cultural, epistemic, social, and political diversities of all the social actors involved are considered.

ABSTRACT Objectives: to analyze factors associated, directly and indirectly, with lower social support of older adults, according to sex. Methods: a cross-sectional study, with 941 older adults from a health micro-region in Minas Gerais. Descriptive and trajectory analyzes were carried out (p<0.05). Results: in groups of women and men, direct and significant associations were observed between a smaller social network (p<0.001;p<0.001), single-person housing (p=0.046;p<0.001), greater number of depressive symptoms (p<0.001;p=0.010) and lower participation in advanced activities (p<0.001;p=0.005) with lower social support. In women, younger age was directly and significantly associated with outcome (p<0.001). In men, older age, mediated by lower participation in advanced activities, was indirectly associated with outcome. Conclusions: men and women showed less social support associated with social network, housing arrangement, depressive symptoms and participation in advanced activities. Understanding the context of social support among older adults makes it possible to establish more effective measures to improve care.

Published: October 2022

RESUMO Objetivo Medir a prevalência de sintomatologia ansiosa entre estudantes de graduação de uma universidade pública no Sul do Brasil, seus fatores associados e possíveis consequências. Métodos Trata-se de um estudo transversal com uma amostra aleatória de graduandos, realizado em 2019. Foi utilizado um questionário com questões sociodemográficas, acadêmicas e de saúde mental e física. Sintomas de ansiedade generalizada foram avaliados por meio do Generalized Anxiety Disorder – 7 (GAD-7). Fatores associados e possíveis consequências foram analisados por meio da regressão de Poisson com ajuste robusto da variância. Resultados Entre os 994 participantes, a prevalência de sintomas de ansiedade generalizada severa foi de 30,9% (IC 95%: 27,9%-33,9%). As variáveis independentemente associadas a sintomas de ansiedade generalizada foram: sexo feminino, orientação não heterossexual, sentir muito/muitíssimo medo de violência no bairro e perceber como difícil o acesso a serviço psicológico. Possuir alto nível de suporte social e apresentar algum nível de atividade física foi considerado fator de proteção para o desfecho. Possíveis consequências dos sintomas de ansiedade generalizada foram: pior qualidade de sono, utilizar algum medicamento sem prescrição nos últimos 30 dias e ser classificado como risco de suicídio moderado/severo. Conclusões Esses resultados demonstram a necessidade de um olhar mais atento para alguns subgrupos populacionais. Recomenda-se a implementação de intervenções psicológicas que incluam um número maior de indivíduos simultaneamente (como a criação de grupos terapêuticos), com o intuito de reduzir a carga de ansiedade no contexto universitário. O fortalecimento do setor de assistência estudantil da universidade também se torna uma importante possibilidade de melhora para esse cenário.
Dris Norms For ‘Keitt’ Mango in Brazilian Semiarid: Diagnosis and Validation
Authors: Tullio Leonardo , Rozane Danilo Eduardo
Published: October 2022

Abstract Nutritional standards based on long-term data improve the nutritional diagnosis of the crop, as they make norms more precise and establish more refined criteria. This study aimed to evaluate the nutritional status of the mango crop using the DRIS methodology to identify nutritional limitations and validate norms. A da-tabase of 202 commercial plots was used, whose leaves were collected in the floral induction period between 2011 and 2018 in the Brazilian semiarid region. The productivity of 'Keitt' mango under the Brazilian semiarid conditions was not related to NBI-DRIS. Nutrient concentration presents positive and significant relationship with the respective DRIS indices, enabling the determination of the balance point, establishing a nutritional standard and enabling the use of foliar diagnosis for the variety. The order of nutrients with the highest frequency of limitations due to lack, in decreasing order, was: Zn > Al > Na > Cu > S > B > Mn > P = K > Fe > Ca > N > Mg, and limitation due to excess, in decreasing order was: Fe > Na > Mg > Al > Cu > B = N > S > Ca > P = K > Zn > Mn.
Demanda e oferta nos planos econômicos
Authors: SATO CLAUDIO SEIJI
Published: October 2022

RESUMO Esta nota estuda as condições de oferta e o comportamento da demanda nos primeiros meses dos planos Cruzado, Collor e Real. A principal conclusão é que, independentemente dos interesses reais, o consumo apresenta um padrão qualitativo semelhante. Portanto, como parece inevitável um aumento no consumo nos primeiros meses, os formuladores de políticas econômicas deveriam criar condições de suprimento antes da implementação dos planos. Sob esse ponto de vista, o Plano Real foi o que apresentou as melhores condições de suprimento em relação aos planos Cruzado e Collor.

Política monetária, depósitos compulsórios e inflação
Authors: GARCIA MÁRCIO G. P.
Published: October 2022

RESUMO Desde o início do Plano Real, o governo tem recorrido a depósitos compulsórios muito mais elevados sobre o passivo dos bancos, bem como à criação de depósitos compulsórios sobre crédito (ativo de um banco) na tentativa de restringir a expansão dos agregados monetários e do crédito. A intenção da política estava certa, embora o desenho do perfil dos requisitos de reservas, ou seja, a estrutura relativa dos requisitos de reservas sobre os passivos do banco diferente, fosse falho. Isso ocorre porque há uma exigência de reserva muito alta (inicialmente 100% marginal) sobre os depósitos à vista, que é o passivo que normalmente cresce mais quando as altas inflações diminuem. Desde o início de 1995, as mudanças tributárias tornaram lucrativa a transferência até mesmo de fundos de muito curto prazo de depósitos à vista para fundos mútuos de curto prazo. Além disso, quando essa transferência é realizada, o depósito compulsório geral cai substancialmente. A principal recomendação de política é usar tanto o perfil dos compulsórios quanto a estrutura tributária de modo que a riqueza financeira agregada seja distribuída entre seus diversos componentes de forma compatível com a baixa inflação. Isso evitará futuras realocações de carteira, aumentando a eficácia da política monetária.

RESUMO O autor resgata a teoria do desenvolvimento para ilustrar as diferenças notáveis entre os padrões e resultados da acumulação capitalista nas regiões centrais e periféricas. Enquanto nas primeiras o resultado foi o aumento dos salários e da qualidade de vida, conclui que nas regiões periféricas houve o recrudescimento das desigualdades sociais e dos padrões de dominação, para, a partir dessas reflexões, estabelecer o conceito de subdesenvolvimento e refletir meios de superá-lo.
VÍNCULO DE TRABALHO & ADOECIMENTO DOCENTE: ANÁLISE DAS LICENÇAS DOS PROFESSORES DA REDE ESTADUAL DE EDUCAÇÃO DE MINAS GERAIS

Published: October 2022

RESUMO: Este artigo aborda as licenças para tratamento de saúde dos professores da educação básica da Rede Estadual de Educação de Minas Gerais (REE/MG), por tipo de vínculo jurídico de trabalho (efetivo ou designado), no período compreendido entre 2016 e 2018. Trata-se de um estudo de caso, desenvolvido por meio de pesquisa documental, pesquisa quantitativa (análise descritiva de dados) e realização de entrevistas. Concluiu-se que, curiosamente, os professores designados apresentam um número de licenças menor do que os professores efetivos; entretanto, os seus afastamentos são significativamente mais duradouros. Uma análise apressada desse fato poderia deduzir que, contrariando a hipótese inicial do estudo, os professores efetivos adoecem mais do que os professores designados. Todavia, neste artigo, defende-se que esse é, na verdade, um forte indicativo de que os professores designados padecem de adoecimentos de maior gravidade do que os professores efetivos, o que corrobora a hipótese inicial deste estudo, em termos. Os resultados apontam para o adoecimento no exercício da função de magistério e apresentam um alerta importante a respeito da utilização do vínculo precário da designação, o qual teve recentemente sua inconstitucionalidade parcial declarada pelo Supremo Tribunal Federal.

RESUMO: Este artigo procura pensar as bases de uma possível crítica empreendida por Michel Foucault em torno do neoliberalismo e da sua relação com a educação. Desenvolve-se uma leitura bibliográfica que percorre os trabalhos elaborados por Foucault a partir de uma história política da governamentalidade. Procurar-se-á demonstrar que o neoliberalismo, aos olhos de Foucault, deve ser compreendido tal qual um modo de vida e uma prática de governo responsável pela produção de modos de subjetivação identificados com o empresariamento de si mesmo como estética da existência neoliberal. Em um primeiro momento, serão percorridos os contornos do pensamento foucaultiano em torno de uma genealogia das artes de governo e dos processos de subjetivação. O segundo momento será dedicado a procurar compreender os efeitos pelos quais o neoliberalismo constitui-se enquanto um ethos responsável por produzir uma experiência de uma educação capitalizada e financeirizada. Finalmente, nossas considerações finais serão dedicadas à elaboração de uma crítica em torno do regime de governamentalidade neoliberal a partir das contribuições elaboradas por Michel Foucault.

ABSTRACT: This paper considers the foundations of a possible Michel Foucault critique of neoliberalism and its relationship to education.We will attempt to demonstrate how neoliberalism, in Foucault's thought, should be understood as a way of life and as a government practice responsible for the production of modes of subjectivation identified with self-entrepreneurship as the aesthetics of neoliberal existence based on a bibliographic survey that covers the works developed by Foucault from a political history of governmentality.At first, we go through the contours of Foucault's thinking around a genealogy of the arts of government and the processes of subjectification. The second moment is dedicated to trying to understand the effects by which neoliberalism is constituted as an ethos responsible for producing the experience of a capitalized and financialized education. Our final considerations are dedicated to the elaboration of a critique of the neoliberal governmentality regime based on the contributions made by Michel Foucault and your criticism.
Physico-chemical properties of calcium silicate-based sealers in powder/liquid and ready-to-use forms
Authors: Janini Ana C P , Pelepenko Lauter E , Gomes Brenda P F A , Marciano Marina A
Published: October 2022

Abstract Calcium silicate-based root canal sealers have been developed in powder/liquid or premixed ready-to-use forms. The evaluation of the physico-chemical properties of a prototype powder/liquid MTApex Sealer (Ultradent) in comparison to a ready-to-use material EndoSequence BC Sealer (Brasseler) was performed. The paste/paste epoxy resin-based AH Plus (Dentsply) served as control for comparisons. The sealers were evaluated (n = 6) regarding setting time (in dry and moist environments), flow and radiopacity, following the ISO-6876/2012 standard. Also, the pH was assessed. Material’s surface and chemical characterization was evaluated using scanning-electron-microscopy (SEM) and energy-dispersive-spectrometry (EDS). Mixed ANOVA, Shapiro-Wilk, Levene, and post-hoc analysis with Bonferroni correction were performed at a significance level of 5%. MTApex Sealer exhibited the highest flow and EndoSequence BC Sealer had a significantly longer setting time in dry compared to the moist environment; however, for MTApex Sealer and AH Plus no significant changes occurred when additional moisture was provided. All materials exceeded 7 mm Al of radiopacity and showed a decreasing alkalinity over the 21 day-analysis. SEM/EDS evaluation resulted in peaks of calcium, silicon, and the respective radiopacifier. The prototype powder/liquid MTApex Sealer had the highest flow and similar setting time in both dry and moist environments; opposingly, EndoSequence BC Sealer was crucially influenced by external moisture. This suggests that the powder/liquid materials’ setting seems to be more predictable.

Abstract The present study analyzed the expression of proteins involved in the sonic hedgehog signaling pathway (SHH, SMO, and GLI-1) in benign epithelial odontogenic lesions (odontogenic keratocyst - OKC, ameloblastoma - AB, and adenomatoid odontogenic tumor - AOT) in order to identify the role of these proteins in the pathogenesis of these lesions. The sample consisted of 20 OKCs, 20 ABs, and 10 AOTs. The Kruskal-Wallis, Mann-Whitney U, and Spearman’s (r) tests were used for statistical analysis, with the level of significance set at 5% (p < 0.05). The membrane/cytoplasmic expression of SHH was significantly higher in AB compared to AOT (p = 0.022) and OKC (p = 0.02). No differences were found in the membrane/cytoplasmic expression of SMO between the lesions studied. Regarding GLI-1, significant differences were observed at the nuclear level for AB and OKC compared to AOT (p < 0.0001). In addition, significant positive correlations were found between cytoplasmic and nuclear GLI-1 in AB (r = 0.482; p = 0.031) and OKC (r = 0.865; p < 0.0001), and between membrane/cytoplasmic SMO and cytoplasmic GLI-1 in AOT (r = 0.667; p = 0.035) and OKC (r = 0.535; p = 0.015). The results of this study confirm the participation of the sonic hedgehog signaling pathway in the pathogenesis of the lesions studied. Overexpression of SHH in ABs and nuclear expression of GLI-1 in ABs and OKCs indicate that these proteins contribute to the more aggressive behavior of these two lesions when compared to AOT.

Abstract This study assessed the cell viability, cytokine production, and mineralization potential of human dental pulp cells (hDPCs) after exposure to lipopolysaccharide (LPS) and application of calcium silicate-based materials (CSBM). Characterization of the CSBM was performed by infrared spectroscopy (n = 3). Extracts of Bio-C Repair, Biodentine, Cimmo HD, and MTA Repair HP were prepared and diluted (1:1, 1:4, and 1:16). Culture of hDPCs was established and treated or not with 1 µg/mL of LPS from Escherichia coli for 7 days. MTT assay was used to assess cell viability at 24, 48, and 72 h (n = 6). Alkaline phosphatase (ALP) activity was assayed on day 7 (n = 4). Il-10 and TNF-α were quantified by ELISA at 24 h (n = 6). Data were analyzed by ANOVA and Tukey’s test (α = 0.05). Cell viability of LPS-activated hPDCs was higher than untreated control in 48 and 72 h (p < 0.05). Differences between non-treated and LPS-activated hPDCs were observed for Biodentine and Cimmo HP (p < 0.05). The CSBM influenced the cell viability (p < 0.05). ALP activity was higher in LPS-activated hDPCs (p < 0.05). No changes in the concentration of TNF-α were observed between groups (p > 0.05). The CSBM increased the Il-10 production (p < 0.05). LPS-activated hDPCs presented increased cell viability and ALP activity. The CSBM showed mild toxicity and was able to enhance the cell viability and mineralization potential of untreated and LPS-activated hDPCs. The CSBM also induced anti-inflammatory mechanisms without compromising pro-inflammatory ones.

ABSTRACT: Big chili has the largest fruit size compared to other types of chili. In addition to having a spicy taste, big chilies contain other beneficial biochemicals such as phenolics, flavonoids, antioxidants, and α-glucosidase inhibitors that have the potential to be developed for functional tropical plants. Information on the content is still not widely found. Therefore, this study identified biochemical compounds (TPC, TFC, DPPH, FRAP, AGI) in several genotypes of big chili peppers. From October to November 2021, we conducted a study using the microplate reader method. We repeated the experiment three times. The research design used was a completely randomized design with a single factor genotype. A total of 22 genotypes of big chili were used in this study. The big chili genotype F6074136-2-3-2-3 had the highest content of α-glucosidase inhibitor and antioxidant FRAP compared to other genotypes 67.62% and 71.20 mol TE/g extract. The genotypes CK 12 and F6074077-1-1-3-1 indicated the highest phenolic and flavonoid contents. The correlation between biochemical parameters showed that TPC-AGI and TPC-DPPH were significantly negatively correlated. The conclusion is that the information in this study can be the basis for the development of functional tropical plants in future research.

Authors: Cui Zhihao , Wang Zhiang
Published: October 2022

ABSTRACT Introduction: Synchronized swimming is a sport of artistic expression, skill, and physical fitness. Explosive, high-intensity movements rely mainly on the athlete’s good basal strength. Although China attaches great importance to the physical training of synchronized swimming athletes, there is no theoretical achievement in consolidating specific training. Objective: To analyze the impact of CORE strengthening on the physical training of synchronized swimming athletes. Methods: This article selects 30 synchronized swimmers as volunteers for the research. A basal metabolism test was used to verify the maximal oxygen consumption (VO2max), ventilatory anaerobic threshold (VT), and other indicators. The isokinetic force measurement system measured the athletes’ maximum lumbar-abdominal muscle flexion/extension torque, explosive strength, fast muscle strength capacity, total work, and anti-fatigue capacity. Results: The synchronized limb training results of the swimming team were positively correlated with the stability of the CORE muscles. There is a positive relationship between 30 years old and maximal strength training and performance in athletes. Abdominal muscular endurance showed the highest correlation coefficient with synchronized swimming performance. Conclusion: Coaches should organize adequate strength training according to the growth and development characteristics of athletes and the characteristics of synchronized swimming movements. In this way, an excellent physical training effect can be achieved by CORE training. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Shu Li
Published: October 2022

ABSTRACT Introduction: Physical conditioning is an essential component of sports skills. The main routine training methods for skill enhancement in martial arts players should be based on traditional movements. Core strength training has also been shown to be valid for the physical conditioning of martial arts players. Objective: This paper studies the qualitative changes in the balance of martial arts athletes caused by the insertion of core strength training. Methods: This paper selects 24 martial arts players by sampling and randomly divides them into control and experimental groups. The biomarkers of the volunteers were stored and processed under statistical methods to organize and display the data. Results: The experimental and control groups showed high statistical significance in each index after testing (P<0.05). The results show that the methods used in the experimental and control groups can effectively improve their performance in core and key explosive movements during exercise. There were very significant changes in the extensor muscle peak in both groups. The experimental group showed more significant improvement than the standard group (P<0.05). The experimental group’s flexor peaks showed a more significant difference than the control group. In contrast, the experimental group showed a more remarkable improvement than the standard group (P<0.05). Conclusion: Core resistance exercise can effectively promote a center of gravity balance in martial arts athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Ji Haiying , Yu Lirong
Published: October 2022

ABSTRACT Introduction: The modern pentathlon requires athletes to participate in 5 individual sports (fencing, swimming, equestrian, running, and shooting combined) in one day. All of these belong to different categories, resulting in high demand for physical and mental control by the athlete. The importance of psychological factors in everyday physical activity has increased attention. Objective: This paper explores the role of comprehensive psychological training in modern pentathlon. Methods: Forty-seven modern pentathletes were selected by random sampling method. A questionnaire survey method was used to analyze the volunteers. Interviews on the psychological status of the athletes before the competition were also conducted. Finally, a statistical method was used to determine the participants’ interview and questionnaire results. Results: The athletes in all five sports experienced high stress before the competitions. The second highest stress was during preparation, before the games. The incidence of anxiety, indifference, and disproportionate confidence before the competition was lower. Conclusion: The psychological state of modern pentathletes before competition is directly related to their competitive state and level. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Yao Wenchao
Published: October 2022

ABSTRACT Introduction: Long-distance runners cannot achieve training effects by relying only on speed endurance training. Core training exercises significantly improve stability, allowing learning of techniques with superior movement efficiency. Several factors that affect the development of athletes’ special skills are considered, highlighting their main strengths and working on intermediate characteristics. Objective: Verify the impacts of core training on athletes’ performance in long-distance running. Methods: This paper had 18 middle-distance runners as volunteers for the research. The athletes’ physical conditioning and athletic performance before and after training were examined. Statistical analyses on the indicators of the experimental and control groups were analyzed based on the T-test. Results: There were significant differences in endurance, core muscle elasticity, core strength, explosive power, and stability (P<0.05); the results showed that the differences in core stability between the left and right legs of the experimental group were significant (P<0.05). Conclusion: Core strength exercise is more conducive to exercising a myocardial group in medium and long-distance exercise than conventional strength exercise. Core strength exercises can compensate for a lack of regular strength. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Liu Yuanting
Published: October 2022

ABSTRACT Introduction: Volleyball is a technical and team game where individual physical conditioning of the athletes has a fundamental role in the competition. The maintenance of this physical conditioning includes the optimization of physical function and the gain of body resistance. The ability to respond in front of a defensive game in the game of volleyball is one of the main keys to determining their defensive skills and overall defensive level. Objective: Investigate the reflexes of volleyball players during an athletic competition match. Methods: This was done by analyzing the avoidance rate and reaction time of 14 volunteers, volleyball players. The experimental method quantitatively measured the individuals’ defense ability and reaction time. Finally, the statistical correlation test was used to obtain the correlation between the two results. Results: The practice time with games had a more significant impact on the performance of volleyball players. The players’ cut-off point is limited to the lowest level. Their peaks have little effect on the defense rate of volleyball. Ball height shows that the index has a very good relationship with defensive ability. Conclusion: Reaction time in volleyball can be used to judge the level of player defense and select the most appropriate players for each moment of competition. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
