Published: June 2021

The objective of this study is to evaluate the plasma treatment effects on oral fungal biofilms. Candida albicans biofilms were developed on the 48-well plate to serve as a model of oral fungal biofilm. The treatment of 0.2% chlorhexidine digluconate (CHX) was used as a positive control compared with plasma treatments. The efficacy of treatments was determined by 3-(4,5-dimethylazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and confocal laser scanning microscope (CLSM). The survival percentage of Candida albicans decreased from 52% to 27% as the plasma power increased from 6mA to 8mA and plasma exposure time extended from 2 min to 10 min. Moreover, it was found that there is a synergistic effect of the combination of plasma and CHX treatments. Scanning electron microscopy (SEM) examination indicated severe cell damages resulting from plasma treatment. In conclusion, the low-temperature plasma treatment is effective in deactivating Candida albicans biofilms and thus provides a promising alternative to disinfect oral fungal biofilms.

UMA ANÁLISE SOBRE A PRODUÇÃO ACADÊMICA DA PRIMEIRA TURMA DO MESTRADO NACIONAL PROFISSIONAL EM ENSINO DE FÍSICA
Authors: Rebeque Paulo Vinícius , Ostermann Fernanda , Viseu Sofia
Published: June 2021

O programa de Mestrado Nacional Profissional em Ensino de Física (MNPEF) teve início no ano de 2013 com 21 polos regionais. Seguindo as características de um curso de Mestrado Profissional em Ensino (MPE), o modelo de trabalho de conclusão de curso para o MNPEF consiste no desenvolvimento de um produto educacional e uma dissertação. Nessa perspectiva, com base nos contributos teóricos da Sociologia da Ação Pública e da Filosofia da Linguagem de Bakhtin, tivemos como objeto de investigação os 230 trabalhos de conclusão oriundos da primeira turma do MNPEF. Encontramos em nossa análise elementos intrínsecos relativos ao conteúdo temático destes enunciados: cerne da proposta didática, referencial (is) teórico (s) adotado (s), conteúdos de Física e público de aplicação do produto educacional. Com isso, foi possível identificarmos um formato característico para os enunciados analisados, o que nos indica a influência do meio acadêmico em geral (estrutura composicional e estilo de linguagem) e do contexto normativo do MNPEF em específico (conteúdo temático) no processo de elaboração para os trabalhos de conclusão. Entretanto, convém destacarmos que há trabalhos que não necessariamente seguem as tendências acadêmicas, sobretudo por dialogarem com a realidade escolar externa ao MNPEF.
A MOBILIZAÇÃO DO CONHECIMENTO PEDAGÓGICO DO CONTEÚDO SOBRE AS LEIS DE NEWTON: ANÁLISE DE UMA SEQUÊNCIA DIDÁTICA PRODUZIDA POR UM RESIDENTE DE CIÊNCIAS DA NATUREZA
Authors: Venceslau da Cruz Silva Boniek
Published: June 2021

Neste trabalho, compreendemos que a noção de conhecimento pedagógico do conteúdo (Pedagogical Content Knowledge - PCK, em inglês) de Shulman (1986; 1987) pode servir como ferramenta de interpretação do processo de transformação de conteúdos físicos em conhecimentos ensináveis no ensino fundamental. Em especial, usamos o modelo de PCK de Ciências, proposto por Magnusson, Borko e Krajcik (1999), para compreender como um residente de Ciências da Natureza mobiliza o seu PCK na construção de uma sequência didática sobre as leis de Newton. Como primeiros resultados, encontramos que um forte conhecimento de conhecimentos de currículo e estratégias didáticas do residente foram fatores primordiais desta empreitada. Destacamos, também, que o processo de construção de sequências didáticas afloram algumas deficiências formativas do residente, como, por exemplo, atreladas aos conhecimento de avaliação de seus estudantes. Por fim, sugerimos que, principalmente, os cursos de formação inicial oportunizem momentos para o desenvolvimento do PCK de futuros professores de Ciências e, em especial, que sejam oportunizados mais momentos de pontes entre a teoria e a prática, como o Pibid e a Residência Pedagógica, que são momentos nos quais seus PCK’s são mais fortemente desenvolvidos e mobilizados desde a construção de propostas de ensino até sua execução.

Authors: D'Aquino Rosa Marcelo
Published: June 2021

O artigo aborda a temática da avaliação em uma formação continuada, sendo participantes do projeto alguns professores de Ciências do Ensino Fundamental da região do Alto Vale do Itajaí, Santa Catarina. Partindo-se do problema referente à questão da avaliação nos processos de ensino e aprendizagem em aulas de Ciências da Natureza, o presente relato teve como objetivo geral identificar quais as concepções sobre avaliação entre os docentes que participaram formação conduzida pelo autor. Ao longo do percurso formativo, os professores evidenciaram inicialmente concepções de avaliação voltadas para a noção de um instrumento avaliativo (prova, trabalho, relatório, seminário etc), enquanto noções mais amplas do processo foram manifestadas ao final do encontro. Tomando como base as perspectivas de avaliação de teóricos como Luckesi e Perrenoud, trabalhou-se também com o referencial metodológico da Análise de Conteúdo, analisando as respostas dos professores a uma tempestade de ideias referente à temática avaliação, onde os participantes deveriam expressar sua concepção sobre o termo em uma palavra. Por fim, acredita-se que algumas concepções iniciais foram quebradas ou modificadas, pois os professores manifestaram ideias diferentes após uma discussão conduzida pelo professor-formador, visando ampliar o conceito de avaliação.

The article describes the problems of production veterinary and sanitary control of raw materials and products at meat industry enterprises in the light of modern requirements of science and market economy. The authors discuss ways to increase the effectiveness of state veterinary and sanitary supervision in all areas of production of animal products. Particular attention is paid to the training and retraining of veterinary specialists in veterinary expertise. There is a need to increase the level of knowledge and professional experience in the inspection work and to realize responsibility for the results of activities in any area of production. Additional vocational training was recommended for private entrepreneurs and owners of enterprises engaged in the processing and sale of animal products on sanitation and hygiene in the production workshops of enterprises of the agro-industrial complex. Practice shows that veterinary doctors with only good training in all issues of input, operational and output control, who have undergone additional professional training 210 in special programs, can effectively carry out vetsanexpertiza at various facilities. To do this, it is necessary to develop and approve a unified program for certification of veterinary specialists for the whole country, taking into account the peculiarities of servicing various industry enterprises. The development of such a program should be entrusted to experienced workers of industry universities, research institutes and vetsanexpertiza laboratories. It should reflect the theoretical training and practical activities of veterinary specialists at meat producing plants, sausages and canneries, refrigerators and in state vetsanekpertiza laboratories at markets and fairs. If the problems of the State Veterinary Control at the agro-industrial complex enterprises are not solved today, then the situation of production hygiene and veterinary and sanitary control of raw materials and finished products will later require significant legislative and legal adjustment, high financial costs and improved standards of relations between food producers and their consumers. State veterinary control of raw materials and products is the basis for food security of the population.

The aim of this work was to study the relationship between the isolates of Bacillus subtilis EFS, Lactobacillus plantarum, Propionibacterium freudenreichii, Lactococcus lactis, and Strepto-coccus lactis, which have the potential for the development of a bacterial preparation that improves the safety of plant-based feed during harvesting and storage. The possibility of using the tested iso-lates as part of the association was identified by the drip method, which is high quality and most suitable for primary testing. The method involved direct joint cultivation of microorganisms on the surface of a dense nutrient medium and visual assessment of signs of suppression or enhancement of the growth of one culture by another. As a result of the study, the following types of interactions between microorganisms were identified: neutrality, contact progression, antagonism, and contact regression. For inclusion in the association, isolates that showed neutrality and contact progression to each other were selected. The corresponding types of relationships were characteristic of B. sub-tilis EFS, L. plantarum, P. freudenreichii, and L. lactis isolates. Based on this, six recipes were formed that are promising for further research in order to develop a biological preparation that helps to improve the safety of plant-based feed during harvesting and storage.

OBJECTIVE

The use of osteobiologics, engineered materials designed to promote bone healing by enhancing bone growth, is becoming increasingly common for spinal fusion procedures, but the efficacy of some of these products is unclear. The authors performed a retrospective, multi-institutional study to investigate the clinical and radiographic characteristics of patients undergoing single-level anterior cervical discectomy with fusion performed using the osteobiologic agent Osteocel, an allograft mesenchymal stem cell matrix.

METHODS

The medical records across 3 medical centers and 12 spine surgeons were retrospectively queried for patients undergoing single-level anterior cervical discectomy and fusion (ACDF) with the use of Osteocel. Pseudarthrosis was determined based on CT or radiographic imaging of the cervical spine. Patients were determined to have radiographic pseudarthrosis if they met any of the following criteria: 1) lack of bridging bone on CT obtained > 300 days postoperatively, 2) evidence of instrumentation failure, or 3) motion across the index level as seen on flexion-extension cervical spine radiographs. Univariate and multivariate analyses were then performed to identify independent preoperative or perioperative predictors of pseudarthrosis in this population.

RESULTS

A total of 326 patients met the inclusion criteria; 43 (13.2%) patients met criteria for pseudarthrosis, of whom 15 (34.9%) underwent revision surgery. There were no significant differences between patients with and those without pseudarthrosis, respectively, for patient age (54.1 vs 53.8 years), sex (34.9% vs 47.4% male), race, prior cervical spine surgery (37.2% vs 33.6%), tobacco abuse (16.3% vs 14.5%), chronic kidney disease (2.3% vs 2.8%), and diabetes (18.6% vs 14.5%) (p > 0.05). Presence of osteopenia or osteoporosis (16.3% vs 3.5%) was associated with pseudarthrosis (p < 0.001). Implant type was also significantly associated with pseudarthrosis, with a 16.4% rate of pseudarthrosis for patients with polyetherethereketone (PEEK) implants versus 8.4% for patients with allograft implants (p = 0.04). Average lengths of follow-up were 27.6 and 23.8 months for patients with and those without pseudarthrosis, respectively. Multivariate analysis demonstrated osteopenia or osteoporosis (OR 4.97, 95% CI 1.51–16.4, p < 0.01) and usage of PEEK implant (OR 2.24, 95% CI 1.04–4.83, p = 0.04) as independent predictors of pseudarthrosis.

CONCLUSIONS

In patients who underwent single-level ACDF, rates of pseudarthrosis associated with the use of the osteobiologic agent Osteocel are higher than the literature-reported rates associated with the use of alternative osteobiologics. This is especially true when Osteocel is combined with a PEEK implant.
Prolegômenos da teologia natural em Tomás de Aquino: a possibilidade de um conhecimento racional de Deus
Authors: Frezzato Anderson
Published: June 2021

Este artigo visa resgatar os princípios da Teologia Natural no pensamento de Tomás de Aquino no que se refere à possibilidade de um conhecimento racional de Deus. Tomás, influenciado pela filosofia de Aristóteles, vai afirmar que pela razão pode-se chegar à certeza da existência de Deus. Certeza essa que é evidente, mas que precisa ser demonstrada. Para tanto, elabora cinco vias, chamadas de Provas, para comprovar a existência da divindade baseando-se sempre no pressuposto de que todo conhecimento racional tem sua origem na experiência. Todo o trabalho de Tomás de Aquino possui uma continuidade na Filosofia Contemporânea, sendo estudado e desenvolvido por diversos autores que dão forma ao movimento tomista, particularmente dialogando com outras ciências.
Medo: o novo mal-estar da humanidade

Published: June 2021

Incerteza, insegurança e vulnerabilidade tornaram-se lugares comuns nas sociedades contemporâneas. Este artigo pretende uma reflexão interdisciplinar sobre a construção social e política do medo na modernidade líquida. Zygmunt Bauman, Leonidas Donskis, Martha Nussbaum, Hannah Arendt, Ulrich Beck, Boaventura de Sousa Santos, Bernard Henry-Levy e Umberto Eco são alguns dos autores que iremos colocar em diálogo para melhor compreender as múltiplas narrativas do medo numa era profundamente marcada pela destruição das certezas sociais, pelo agravamento das desigualdades sociais, pelas lógicas de um capitalismo predador, pelo ressurgimento de nacionalismos de exclusão, bem como de particularismos étnico-culturais, que se movem a partir de discursos xenófobos e racistas e, por fim, pelos novos riscos, como a degradação ecológica e como a pandemia COVID19, que atualmente assola as sociedades contemporâneas e domestica os comportamentos sociais.
Machiavelli and republicanism in Elizabethan England
Authors: Cerqueira Marcone Costa
Published: June 2021

The purpose of this succinct work is to present N. Machiavelli's classic republican view from his proposition of an inevitable paradox, the founding of an expansionist republic, difficult to govern, or the founding of a stable, but small and weak republic. Such a paradox, according to Machiavelli, should direct and condition all the constitutive devices of the republic when choosing what will be its destiny as a political body. The model of republic preferred by the Florentine will be the expansionist model of Rome, leading him to assume all the devices that gave this republic its power. From this presentation of the Machiavellian proposition, we will analyse the assimilation of republican thought in England from the Elizabethan period, as well as the political-social scenario that exists there. This itinerary will allow us to understand, in general, why classical republicanism was received on English soil from the perspective of establishing a mixed, stable government, thus favouring the spread of the Venice myth as a serene republic and delaying the use, even that mitigated, of the republican presuppositions expressed in the Machiavellian work that directed towards a Roman model.
O mundo é o grande espelho da consciência: reflexões sobre as implicações quânticas do idealismo absoluto de Hegel
Authors: Ferraz Bueno Sinésio
Published: June 2021

No campo de estudos em física quântica, o pensamento de Heisenberg suscita reflexões muito relevantes para uma articulação entre ciência e metafísica, dada a importância atribuída ao sujeito no colapso da superposição entre onda e partícula. Sob uma perspectiva idealista, a importância dada ao sujeito na observação dos fenômenos quânticos pode ser considerada uma etapa do desenvolvimento da consciência no âmbito da fenomenologia do espírito de Hegel. A física quântica, sob uma perspectiva idealista, representa um momento fundamental no reconhecimento e superação dialética dos dualismos produzidos pelo próprio sujeito em sua relação com o mundo.
Diferença e oposição: uma controvérsia
Authors: Dias de Andrade André
Published: June 2021

Os trabalhos cumpre dois propósitos. Tem como objetivo amplo relativizar a divisão entre o estruturalismo e sua pretensa superação ou prosseguimento, com o pós-estruturalismo. O faz a partir de um procedimento específico: o modo como Saussure desenvolve e antecede teses caras a filosofia da diferença de Deleuze. Inicia pela crítica que Deleuze endereça ao estruturalismo do primeiro como incapaz de apreender tanto a diferenciação quanto a organização das diversas formas de experiência. O foco em Saussure se deve ao fato de que Deleuze considera este um descobridor da diferença no âmbito da linguagem, embora insista em lê-la em termos opositivos e, portanto, negativos. Um “descobridor encobridor”, pode-se dizer, que traz à luz a dinâmica diferencial do sentido e, ao mesmo tempo, encobre-a pela imagem tradicional do pensamento que é subordinada à identidade. Em seguida, ficará claro como esta leitura não considera as verdadeiras posições da filosofia da linguagem elaborada por Saussure e que esta deve em muito ser afastada de alguns dos seus considerados herdeiros e seguidores (consideramos o caso exemplar de Trubetskoy, tal como o fizera o próprio Deleuze noutro sentido). A conclusão é que a teoria do valor voltada ao sistema linguístico antecede a teoria diferencial das faculdades que Deleuze emprega a compreender cada das estruturas de nossa existência.

Bu araştırmanın amacı, ortaokul Türkçe ders kitaplarında yer alan yazma becerisini geliştirmeye yönelik etkinliklerin süreç temelli yazma yaklaşımının aşamaları açısından incelenmesidir. Bu amaç doğrultusunda beşinci, altıncı, yedinci ve sekizinci sınıf Türkçe ders kitaplarındaki yazma etkinliklerinde süreç temelli yazma yaklaşımının hangi aşamalarına yer verildiği araştırılmıştır. Doküman incelemesi yönteminin kullanıldığı araştırmada; ortaokul Türkçe ders kitaplarındaki yazma etkinlikleri incelenen dokümanları oluşturmuştur. Bu araştırmada 2019-2020 eğitim-öğretim yılında; ortaokul için hazırlanan, Millî Eğitim Bakanlığı, Talim ve Terbiye Kurulu’nun ders kitabı olarak kabul ettiği Türkçe ders kitapları doküman olarak kullanılmıştır. Araştırmada ölçüt örnekleme yöntemi yoluyla Türkçe ders kitaplarındaki yazma etkinliklerine odaklanılmıştır. Ortaokul Türkçe ders kitaplarındaki yazma etkinlikleri, etkinlik yönergesinden yola çıkılarak temalaştırılmış, süreç temelli yazma yaklaşımının aşamalarını içeren bir kontrol listesi oluşturulmuş ve yazma etkinlikleri bu kontrol listesi kullanılarak incelenmiştir. Elde edilen verilen içerik analizi yoluyla analiz edilmiştir. Araştırma sonucunda süreç temelli yazma yaklaşımının ilk aşaması olan hazırlık aşamasına ders kitaplarındaki etkinliklerin büyük çoğunluğunda yer verildiği saptanırken, ders kitaplarının tüm sınıf düzeylerinde öğrencilerin yazma öncesinde taslak oluşturmalarına yönelik az sayıda etkinliğe yer verildiği tespit edilmiştir. Ayrıca ders kitaplarındaki yazma etkinliklerinde öğrencilerin taslak metinleri gözden geçirip düzenlemelerine yönelik etkinliklere yer verilmemiş, bunun yerine öğrencilerden verilen konuda veya verilen yönerge doğrultusunda metin yazmaları istenmiştir. Redaksiyon/düzeltme aşamasına ve yayımlama/paylaşma aşamalarına yönelik bulgular incelendiğinde ise Türkçe ders kitaplarındaki yazma etkinliklerinde bu aşamalara yeterince yer verilmediği görülmüştür.

BACKGROUND: The role of gluconeogenesis in cancer cells as the reverse pathway for glycolysis is not well known. Several studies of gluconeogenesis in cancer cells still show conflicting results. Expression of key enzymes such as FBP1 and LDHB in cancer tissues may explain the role of gluconeogenesis in tumor development. OBJECTIVE: This study aimed to analyze the expression of FBP1 and LDHB in fibroadenomas and invasive cancers of the breast. METHODS: The immunohistochemical staining technique was used to show the expression of FBP1 and LDHB in formalin-fixed, paraffin-embedded blocks of 32 fibroadenomas and 31 invasive breast cancer samples. RESULTS: FBP1 was expressed by the majority of fibroadenoma (68.7%) and invasive breast cancer (71%) samples. LDHB expression in fibroadenomas was significantly higher than in invasive breast cancers (P = 0.029). The expression of these two enzymes was found in invasive, lobular, and tubular breast carcinoma, and at well, moderately, and poorly differentiated breast malignancy. CONCLUSIONS: High expression of FBP1 and LDHB was found in fibroadenomas and invasive breast cancers. A higher level of LDHB expression was observed in fibroadenomas. These results may indicate the enzymes’ role in the pathogenesis of both breast diseases.

BACKGROUND: AGR2 expression is associated with luminal breast cancer. Overexpression of AGR2 is a predictor of poor prognosis. Several studies have found correlations between AGR2 in disseminated tumor cells (DTCs) in breast cancer patients. OBJECTIVE: This study aims to determine the correlation between anterior Gradient2 (AGR2) expression with the incidence of distant metastases in luminal breast cancer. METHODS: This study was an observational study using a cross-sectional method and was conducted at Wahidin Sudirohusodo Hospital and the network. ELISA methods examine AGR2 expression from blood serum of breast cancer patients. To compare the AGR2 expression in metastatic patients and the non-metastatic patient was tested with Mann Whitney test. The correlation of AGR2 expression and metastasis was tested with the Rank Spearman test. RESULTS: The mean value of AGR2 antibody expression on ELISA in this study was 2.90 ± 1.82 ng/dl, and its cut-off point was 2.1 ng/dl. Based on this cut-off point value, 14 subjects (66.7%) had overexpression of AGR2 serum ELISA, and 7 subjects (33.3%) had not. The mean value AGR2 was significantly higher in metastatic than not metastatic, 3.77 versus 1.76 (p < 0.01). The Spearman rank test obtained a p-value for the 2 tail test of 0.003 (p < 0.05), which showed a significant correlation of both, while the correlation coefficient of 0.612 showed a strong positive correlation of AGR2 overexpression and metastasis. CONCLUSIONS: AGR2 expression is correlated with metastasis in Luminal breast cancer.

OBJECTIVE: The purpose of this study is to determine the effect of Apis dorsata Honey as a complementary therapy on IL-37 levels and fatigue in breast cancer patients undergoing chemotherapy. METHOD: The study used a quasi-experimental pretest-posttest design with a control group. A total of 30 subjects were recruited using a concurrent sampling technique. The intervention group consisted of 15 subjects who received oral honey at a dose of 13 ml (1 tablespoon × 3) for 15 days, and the control group consisted of 15 subjects. The groups’ samples were chosen at random. The Fatigue Symptom Inventory (FSI) was used to assess the side effects of chemotherapy. RESULTS: Although the effect of Apis dorsata Honey on IL-37 levels was not statistically significant (p > 0.05), the group given honey experienced a clinically significant increase in IL-37 levels, with a mean before (632.37514.93) and post (632.37514.93). (1,003.021,248.88). Fatigue decreased statistically significantly in the group given mean honey values prior to 13.205.59 and after 11.805.07 (p = 0.004). CONCLUSION: Honey administration increases IL-37 levels clinically, though the increase is not statistically significant. Giving honey to patients with breast cancer can help alleviate fatigue caused by chemotherapy.
