RESUMO Este artigo visa a demonstrar como a cultura indígena há muito tempo passa ao largo do pensamento visual brasileiro e avalia as possibilidades de se pensar sua história a partir de artistas indígenas. Apresenta revisão teórica e documental acerca das formas como a História da Arte e o pensamento visual desenvolvido no Brasil tratam a produção estético-artística dos povos originários. Propõe a possibilidade de se revisar a história da arte, incorporando o pensamento de artistas indígenas, haja vista a necessidade de uma virada epistemológica na História da Arte para dar conta das diferenças existentes no Brasil e na América Latina.

ABSTRACT This article demonstrate how indigenous culture has long been absent from Brazilian visual thinking and evaluates the possibilities of thinking about its history from indigenous artists point of view. It presents a theoretical and documentary review of the ways in which art history and visual thinking developed in Brazil deal with the artistic aesthetic production of the indigenous peoples. It proposes the possibility of revising the history of art, incorporating the thought of indigenous artists, given the need for an epistemological turn in the History of Art to account for the differences that exist in Brazil and Latin America.

RESUMEN Este artículo tiene como objetivo demostrar cómo la cultura indígena ha sido passada por alto durante mucho tiempo en el pensamiento visual brasileño y evalúa las possibilidades de pensar su historia a partir de artistas indígenas. Presenta una revisión teórica y documental sobre cómo la Historia del Arte y el pensamiento visual desarrollado en Brasil abordan la producción estético-artística de los pueblos originarios. Propone la posibilidad de revisar la historia del arte, incorporando el pensamiento de artistas indígenas, dada la necesidad de un cambio epistemológico em la Historia del Arte para dar cuenta de las diferencias existentes en Brasil y América Latina.

Abstract Silver nanoparticles (AgNPs) are among the most known nanomaterials being used for several purposes, including medical applications. In this study, Calendula officinalis L. flower extract and silver nitrate were used for green synthesis of silver nanoparticles under red, green and blue light-emitting diodes. AgNPs were characterized by Ultraviolet-Visible Spectrophotometry, Field Emission Scanning Electron Microscopy, Dynamic Light Scattering, Electrophoretic Mobility, Fourier Transform Infrared Spectroscopy and X-ray Diffraction. Isotropic and anisotropic silver nanoparticles were obtained, presenting hydrodinamic diameters ranging 90 - 180 nm, polydispersity (PdI > 0.2) and moderate stability (zeta potential values around - 20 mV).

Resumo: En | Texto: En | PDF: En

The aim of this paper was to determine the influence of machining parameters on the surface layer, and consequently on the electrochemical properties, of ASTM F138 austenitic stainless steels. Eight different surface conditions were generated in cylindrical samples by turning and polishing. The surface was characterized by surface roughness Ra and Rt, Vickers microhardness and microstructural characteristics. Cyclic voltammetric tests were performed to evaluate the potential of repassivation and pitting. The surfaces were analyzed by Scanning Electron Microscopy after the electrochemical tests were performed. The cutting parameters were identified to have a significant influence, and the feed rate was as influential as the depth of cut. The use of polishing alone is not sufficient to ensure that a surface has good surface integrity. Even with the polishing application, usually used to produce prostheses, a significant reduction in corrosion resistance occurs if care is not taken to minimize surface machining damage. Corrosion resistance is lower and pitting nucleation is higher in the samples with no polishing and with more severe machining parameters. The tests indicated that softer machining parameters can contribute to an increase in the life of implantable components, reducing the probability of localized corrosion, as well as improving the mechanical properties of prostheses.

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

Resumo Importante mediação de práticas culturais, a TV contribui na construção de representações sociais, incluindo a da ciência. Considerando que adolescentes são um dos seus principais públicos, visamos analisar de que forma os conteúdos televisivos podem contribuir para a construção de percepções sobre ciência nesses jovens. Realizamos 12 grupos focais com alunos de escolas públicas e privadas em três cidades brasileiras: Rio de Janeiro (RJ), Belo Horizonte (MG) e Belém (PA). Observamos que, embora estereótipos da ciência e dos cientistas tenham emergido nas discussões, os jovens demonstraram compreender a atividade científica de maneira mais aprofundada, assim como a própria programação televisiva.

Abstract Television is an important mediator of cultural practices and contributes to the construction of social representations, including representations of science. Considering that teenagers are a main target audience, here we analyze how TV content can help build perceptions of science among these young people. Twelve focus groups were held with students from public and private schools in three Brazilian cities: Rio de Janeiro, Belo Horizonte (Minas Gerais), and Belém (Pará). We observed that although stereotypes of science and scientists did emerge in the discussions, the students demonstrated a more detailed understanding of scientific activity, as well as the TV programming itself.

The objective of this work was to develop and characterize liposomes loaded with silver nanoparticles (LAgNPs) to show improvement in stability characteristics. AgNPs were prepared by the green synthesis method with Aloe vera gel extract and exposure to sunlight. Liposomes were prepared by the modified reverse phase method. Particle size, polydispersity index, zeta potential, as well as the scanning electron microscopy (SEM) morphological aspects of AgNPs and LAgNPs were evaluated. In addition, was used flame atomic absorption spectroscopy to determine the amount of AgNP that was encapsulated in liposomes. The AgNPs presented as amorphous and polydisperse structures, with a mean diameter of 278.46 nm and zeta potential of -18.3 mV. LAgNPs had a mean diameter between 321 and 373 nm, the polydispersity index close to 0.2 and a zeta potential around -40 mV, which indicates greater stability to the AgNPs. The images obtained by SEM show semicircular structures for AgNPs and well-defined spherical shape for LAgNPs. The percentage of encapsulation was between 51.81 to 58.83%. These results showed that LAgNPs were obtained with adequate physicochemical characteristics as a release system.

Antibacterial activity and good mechanical properties are some of the characteristics required for an appropriate film dressing. A novel polymer blend was developed for wound healing application. Twenty-four formulations using the polymers chitosan, poly(vinyl alcohol) and/or ɛ-Polylysine and the plasticizer glycerol were designed using factorial design and then the films were prepared by the casting/solvent evaporation method. Seventeen films were obtained among the twenty-four proposed formulations that were characterized by Field Emission Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infrared Spectroscopy (FTIR). Mechanical properties, such as tensile strength (σ), elongation at break (ɛ) and Young’s modulus (Y) as well as antibacterial properties were determined. The best candidate was then further analyzed with regard to porosity, Water Vapor Transmission Rate (WVTR), swelling and cytotoxicity experiments. The results showed a film with semi-occlusive characteristics, good mechanical properties and no toxic. Incorporation of ɛ-Polylysine increased antibacterial activity against gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus) bacteria.

Abstract This is a case report about the only confirmed death in the State of Espírito Santo due to acute Chagas-related myocarditis in a 2-year-old child living in the rural area of Guarapari. He presented with fever, abdominal pain, headache, and vomiting, resulting in death 21 days after the presentation of symptoms. Amastigote forms were observed in the myocardial fibers in histological examination. The boy’s mother had reported finding “kissing bugs” in the child’s hand. This case highlights the need to include Chagas disease in the differential diagnosis in health care to provide early treatment and avoid death in affected individuals.

RESUMO: Uma pesquisa de agentes enteropatogênicos em gatos domésticos de um abrigo foi realizado como etapa da investigação das causas de diarreias crônicas intermitentes. Amostras fecais individuais de 39 gatos, com livre acesso ao ambiente externo, foram obtidas para pesquisa de helmintos através do exame parasitológico, investigação de parvovírus e coronavírus e de Cryptosporidium spp., Giardia spp. e Tritrichomonas foetus através de PCR em tempo real. Dos gatos avaliados, 30 (76,9%) foram positivos para algum ou mais de um destes agentes entéricos. Desses, 11 (28,2%) apresentaram co-infecções parasitárias. Ovos de helmintos foram observados em 48,7% dos gatos (19/30), 16 felinos (41%) foram positivos para parvovírus ou coronavírus e 25,6% (10/30) estavam infectados por protozoários. Dos positivos para protozoários, cinco apresentaram Tritrichomonas foetus (12,82%), um organismo pouco relatado no Brasil, sendo este o primeiro relato de detecção deste protozoário através de PCR em fezes de gatos no Sul do Brasil e o segundo no país. A diarreia crônica em gatos pode ser multifatorial em animais de abrigo onde a densidade populacional é elevada e os meios de controle parasitário e viral são deficitários, além das condições de higiene precárias. Os fatores associados à proliferação de doenças infecciosas em abrigos promovem o surgimento de infecções por novos patógenos como o Tritrichomonas foetus, até então pouco relatado no Brasil.

ABSTRACT: This study carried out a survey about enteropathogenic agents in domestic cats’ shelter as a stage of investigation for the intermittent chronic diarrhea. Individual fecal samples from 39 cats with free access to the external environment were submitted to parasitological examination, parvovirus, and coronavirus by PCR, and Cryptosporidium spp., Giardia spp. and Tritrichomonas foetus by real-time PCR. From the cats evaluated, 30 (76.9%) were positive for one or more enteric agents, and coinfections were observed in 11 cats samples (28.2%). Helminth eggs were observed in 48.7% of cats (19/30), 16 (41%) were positive for parvovirus or coronavirus and 25.6% (10/30) were infected by protozoa. From the positives for protozoa, five cats were positive to T. foetus (12.82%). The first finding of this protozoan through PCR was in the southern Brazil, and the second was in the whole country. Chronic diarrhea in cats may be multifactorial in shelter animals where the population density is high and the control of parasitic, and viral infections are deficient. Moreover, it is due to poor hygiene conditions in these shelters. The factors associated with the proliferation of infectious diseases in shelters are correlated with new pathogens infections such as T. foetus.

Abstract: Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

Abstract Metallic nanoparticles have great potential as a chemotherapeutic agent. The aim of this study was to develop and characterize silver and gold nanoparticles using a simple method, as well as evaluating the potential cytotoxic activity in relation to the K-562 cell line. For the synthesis, a solution containing the metallic ions was subjected to magnetic stirring with the aqueous extract of Lavandula dentata L. and a change of colour was observed. With the data obtained from the analyses we concluded that the nanoparticles were successfully obtained by a simple and green method using the aqueous extract of L. dentata. The obtained nanoparticles presented a reduced size, a low level of polydispersion, and a homogenous spherical shape. The nanoparticles presented intense and characteristic diffraction peaks, which could be correlated to the planes of the centred cubic structure of the silver and gold. The two formulations presented predominantly crystalline characteristics. The infrared analysis suggested that the amides and alcohols present in the samples may have been responsible for the reduction and limitation of the size and dispersion of the silver and gold nanoparticles. The cytotoxic assay showed that the nanoparticles demonstrated great potential to reduce the cell viability of the K-562 cell line, especially the gold nanoparticles.

Resumo A crise da água em São Paulo, entre os anos de 2013 e 2015, foi considerada uma das maiores de sua história, tendo recebido ampla cobertura das mídias. Problematiza-se como grupos sociais que tem o dever de informar por serem considerados órgãos de Estado, como é o caso dos Comitês de Bacias Hidrográficas, abordam a crise hídrica de São Paulo. Esta questão norteadora moveu a pesquisa quanti-qualitativa das notícias veiculadas nos sites dos Comitês de Bacias que gerenciam o Sistema Cantareira (Comitês Alto Tietê e Piracicaba, Capivari e Jundiaí -PCJ) e da Rede Brasil de Organismos de Bacias Hidrográficas (Rebob).

Abstract The water crisis in São Paulo between 2013 and 2015 was considered one of the greatest in the history of the state, and it was widely covered by the Media. The issue is how groups that are expected to provide information (as they are considered Government bodies, such as the case of the Watershed Committee) tackled the water crisis in São Paulo. This defining issue has driven this quanti-qualitative research on news published in the websites of Watershed Committees that manage the Cantareira System (Committees of Alto Tietê and Piracicaba, Capivari, and Jundiaí -PCJ) and the Brazilian Network of Watershed Organisms (Rebob - Rede Brasil de Organismos de Bacias Hidrográficas).

Resumen La crisis del agua en São Paulo, entre los años 2013 y 2015, fue considerada una de las mayores de su historia, habiendo recibido amplia cobertura de los medios. Se plantea ¿ cómo los Comités de Cuencas Hidrográficas, que son grupos sociales que tienen el deber de informar por ser considerados órganos de Estado, abordan la crisis hídrica de São Paulo? Esta cuestión orientadora movió la investigación cuantitativa de las noticias transmitidas en los sitios de los Comités de Cuencas que gestionan el Sistema Cantareira (Comités Alto Tietê y Piracicaba, Capivari y Jundiaí -PCJ) y de la Red Brasil de Organismos de Cuencas Hidrográficas (Rebob).

Abstract This study evaluated the chemical composition, fatty acid profile, technological quality, sensory profile and microbiological characteristics of rolls with inclusion of 0, 5, 10 and 15% meal prepared with tilapia carcasses. Moisture and carbohydrate content were linearly reduced (P < 0.05) with increasing inclusion of tilapia meal, but a linear increase (P < 0.0001) was observed in protein (9.91 to 14.30%) and ash (1.74 to 4.65%) content. Lipids and calorific value of the rolls were not affected (P > 0.05) by inclusion levels, but 15% tilapia meal resulted in greater amount of polyunsaturated fatty acids (4.63%) in relation to 0% inclusion (4.46%). There was a linear increase (P < 0.0001) in the firmness of the breads (3.65 to 13.17N) and a linear decrease (P < 0.001) in volume and specific volume. Sensory attributes showed a negative linear effect (P < 0.01), with acceptance rates ranging from 85.24% (0% inclusion) to 70.57% (15% inclusion). It can be concluded that the inclusion of 5 to 15% tilapia meal in roll is effective to increase the protein, mineral matter, polyunsaturated fatty acids and the firmness of the roll, in addition to reducing carbohydrates and volume. Considering the reduction in sensory acceptance, it is recommended to use up to 10% tilapia meal in rolls.
