This research was aimed to obtain biodegradable polymeric films with antifungal action against Aspergillus niger, through the addition of copper oxide nanoparticles (CuO-NPs) in the commercial polymer (Ecoflex®) and to evaluate its mechanical, morphological, biodegradation, and copper release properties. The microbiological results showed that the films with 4 wt% CuO-NPs inhibited 97.57% the growth of the fungus growth of 1×105 spores·mL-1 compared to the control. The morphological characterization revealed that the CuO-NPs presented irregular form with particles size of 50 to 400 nm and the XRD showed characteristic peaks of copper oxide. The addition of CuO-NPs to Ecoflex® provided increased maximum and rupture tension, strain, and elasticity modulus the obtained films with 1 wt% CuO-NPs and did not alter the biodegradability of the films. It can be said that, through the addition of CuO-NPs to Ecoflex®, it was possible to add antifungal activity for Aspergillus niger without compromising its biodegradability, meeting the safety standards established by legislation regarding the release of copper.

Abstract: En | Text: En | PDF: En

The Montmorillonite-Erucamide nanocomposite (MMT-EU) can be used to reduce and to control the values of coefficient of friction of low-density polyethylene films (LDPE), widely used by the food industry. In this work, the effect of the addition of 5 wt% and 10 wt% of MMT-EU on the mechanical properties of LLDPE films involving the weld region was investigated. The MMT-EU concentration range was defined considering its possible technological application as an additive to stabilize the friction coefficient of polymeric films. The result shows a significant improvement in the values of stiffness, strength and ductility of polymeric films. In addition, it did not change the coefficient of friction, but the brightness of the LLDPE films decreased and the opacity increased, due to the increase in the crystallinity degree of the LLDPE polymer promoted by MMT-EU, not being a problem for the application of these films.

Abstract: En | Text: En | PDF: En

Composites based on green high-density polyethylene (G-HDPE) and hydroxyapatite (HA) compatibilized with maleic anhydride grafted high-density polyethylene (HDPE-g-MAH) were developed in this work. The main objective was to evaluate the effects of HA and HDPE-g-MAH contents on the mechanical and thermal properties and hydrolytic degradation of composites through design of experiments and statistical analysis, as well as to evaluate the hemolytic stability. Hydroxyapatite acts as a reinforcing agent for the G-HDPE matrix while the HDPE-g-MAH acts as a compatibilizing agent, improving the dispersion of the HA particles in the polymer matrix and thus increasing the mechanical properties. The crystallization temperature and the degree of crystallinity of the polymer matrix were increased with the addition of HA, suggesting the filler acts as a heterogeneous nucleating agent. Hemolysis tests performed on a composite sample with best mechanical performance did not indicate significant hydrolytic degradation, which suggests this composite is a promising material to be used in bone tissue engineering, for application in implants and bone grafts. highdensity high density GHDPE G HDPE (G-HDPE (HA HDPEgMAH g MAH (HDPE-g-MAH work analysis stability engineering grafts

Resumo O artigo tem por objetivo analisar as histórias de vida de portadores de doença de Chagas (DC), para evidenciar em suas narrativas elementos e possibilidades de enfrentamento dessa problemática. Causada pelo protozoário Trypanosoma cruzi, a DC combina condições de infecção assintomática e/ou de progressão para doença de acordo com determinantes biológicos e sociais e afeta 6 a 7 milhões de pessoas infectadas. No mundo anualmente 6 mil pessoas em consequência das complicações na fase crônica da DC. Realizamos um estudo qualitativo com uso da técnica de história de vida coletadas em entrevistas abertas, coletando um material riquíssimo para trabalhar o contexto da doença em múltiplas dimensões. Associamos uma escuta sensível com a necessidade das pessoas vivendo com a DC darem força à sua voz, valorizando sua própria história de vida, transformando-as em detendoras de sua história e de seu conhecimento. A visibilidade emergiu e prevaleceu, expondo a própria doença como tema central e dois subtemas gerais: suas percepções sobre a doença e a sua própria vida, no contexto da doença. Identificamos a necessidade de (re)pensar a problemática da doença de Chagas como algo visível e presente.

Abstract The scope of this article is to analyze the life histories of Chagas disease (CD) patients, searching for elements in their narratives that might present possibilities for coping with this problem. Caused by the protozoan Trypanosoma cruzi, Chagas disease combines conditions of infection and/or progression to disease, in accordance with biological and social determinants and affects around 6 to 7 million people infected with T. cruzi. More than 6,000 people die each year due to complications in the chronic CD phase. This is a qualitative study using the life history technique that was used in open interviews. We collected a wealth of material with which we can work on the context of the disease in multiple dimensions. We associate sensitive listening with the needs of people living with the CD to give strength to their voice, valuing their own life story, transforming them into masters of their history and knowledge. Visibility emerged and prevailed, exposing the disease itself as a central theme and two general sub-themes: their perceptions about the disease and their own life, in the context of the disease. We identified the need to (re)think the problem of Chagas disease as something visible and present.

ABSTRACT In this work, magnesium oxide nanoparticles were synthesized by the sol-gel route and their ecotoxicity was tested in worms of the Eisenia andrei species. Magnesium oxide nanoparticles were characterized by XRD, surface area via BET, TEM and SEM-FEG/EDS. The lethality test with Eisenia andrei earthworm species followed the recommendations of ISO 11268-1 (ISO, 2012) in a completely randomized design with six replicates for each concentration tested (1.06, 2.12, 4.24, 8.48 and 16.96 μg of NPs-MgO/kg of soil), plus the control. The concentrations were mixed to the tropical natural soils, Entisol Typic Quartzipsamments and Oxisol, with no agricultural use history. The morphological and structural analyses of the nanoparticles indicated the formation of magnesium oxide with cubic structure, constituting agglomerates of nanostructures of the order of 20 to 50 nm. The results of toxicity were submitted to analysis of variance (ANOVA One-way), followed by the Dunnett test (p <0.05). Based on standardized toxicological tests it was found that NPs-MgO, at the concentrations tested, did not affect the survival of Eisenia andrei species in the natural soils studied.

Resumo: A germinação da semente do café (Coffea arabica L.) é resultado de eventos que ocorrem simultaneamente no embrião e endosperma. Para entender os mecanismos moleculares responsáveis por estes eventos, nós realizamos uma análise transcricional do embrião e dos endospermas micropilar e lateral de sementes embebidas por 10 dias. O sequenciamento obteve contigs que codificam 16.813 proteínas. Destas, 14.005 (~ 83%) foram altamente similares a pelo menos uma sequência de proteína na base de dados nr. 162 genes foram significativamente expressos em embrião, 36 em endosperma micropilar e 72 em endosperma lateral. A análise de tecido-especificidade dos genes significativamente expressos mostrou que a maior proporção de genes específicos está no embrião (113/162, ~70%), enquanto 11 genes foram expressos nos endospermas lateral e micropilar. No embrião, os genes foram associados principalmente com estresse abiótico, crescimento celular e comunicação intercelular. Nos endospermas micropilar e lateral, eles foram associados com estresse abiótico e degradação da parede celular. A acurácia da análise de RNA-seq foi confirmada por RT-qPCR. Este trabalho acrescenta novas informações sobre os mecanismos moleculares envolvidos na germinação de sementes de café.

Abstract: Germination of the coffee (Coffea arabica L.) seed is the result of events that occur simultaneously in the embryo and endosperm. To understand the molecular mechanisms responsible for these events, we undertook a transcriptome analysis of embryo, micropylar and lateral endosperms from 10-day-imbibed seeds. The sequencing yielded contigs coding for 16,813 proteins. From those, 14,005 (~ 83%) were highly similar to at least one protein sequence in the nr database. 162 genes were significantly expressed in the embryo, 36 in the micropylar endosperm and 72 in the lateral endosperm. The tissue specificity analysis of the significantly expressed genes showed that the embryo had the highest proportion of specific genes (113/162, ~70%), while 11 were expressed in the micropylar and lateral endosperms. In the embryo, genes were mainly associated with abiotic stress, cell growth, and intercellular communication. In the micropylar and lateral endosperms, they were associated with abiotic stress and cell wall degradation. The accuracy of RNA-seq data was confirmed by RT-qPCR. This work adds new information about the molecular mechanism involved in coffee seed germination.

Abstract: En | Text: En | PDF: En

Tetracycline is used to treat various diseases in animals and humans, so its high use causes this substance to be frequently found in effluents and in potable water reservoirs, causing serious problems for human health and the environment. Many processes are applied and evaluated in an attempt to removal tetracycline found in environment, such as adsorption. The application of iron-carbon nanoparticles with core-shell structure (Fe3O4@C) as adsorbent, can be an alternative to removal of these contaminants. In the present study Fe3O4@C nanoparticles were synthesized and used to adsorb tetracycline in aqueous solutions. The core-shell characterization was performed using X-ray diffraction techniques, infrared spectroscopy, surface area, chemical analysis and morphology, and adsorption capacity through isotherms. The results indicated that Fe3O4@C nanoparticles presented good tetracycline removal capability, 73.3%, when applied an initial concentration of antibiotic of the 30 mg L-1 and 0.5 g of adsorbent.

Abstract: En | Text: En | PDF: En

Zinc is an important chemical element in many metabolic mechanisms at low concentrations, but can be toxic when administrated in doses higher than 500 µg·g-1 or 3 mg·L-1. This metal has been detected in many aquatic environments due to several industry activities and swine manure effluents. Thus, the contaminant removal of water and wastewater has been a major challenge. Many processes are applied and evaluated in an attempt to removal zinc found in environment, such as adsorption. In the present study Fe3O4@C core-shell nanoparticles were synthesized and used to adsorb ionic zinc species in aqueous solutions. The core-shell nanoparticles exhibited excellent zinc removal capacity, with a maximum efficiency equal 65% where applied in an aqueous solution containing 10 mg·l-1 of this ionic metal.

Abstract: En | Text: En | PDF: En

Civil construction is one segment responsible for major environmental and social impacts. Among its raw materials, Portland cement, which is produced by the burning and subsequent grinding of a composition of clays and limestones. This manufacturing process causes great environmental damage, both by the exploitation of deposits and by the process of clinkering (burning of raw materials), which emits a significant amount of CO2 in the atmosphere. Therefore, there is a need for research on materials that reduce these impacts on the environment and that can be used by civil construction to the partial replacement of cement. Thus, this research had as objective to produce settlement mortar through the partial replacement of the Portland cement by filler powder, in different proportions and to study its mechanical properties. The results show that the partial replacement of the cement by the residue has acceptable behavior in the mortar.

Objetivou-se avaliar características morfológicas de clones de Panicum maximum durante o período de rebrota após a interrupção da irrigação. Os clones de Panicum foram coletados em Sergipe e em três locais de Pernambuco ("São Bento do Una", "Itambé" e "São João da Coroa Grande"), além das cultivares 'Mombaça', 'Tanzânia' e 'Massai'. Os tratamentos consistiram de sete clones submetidos a 7, 14, 21 ou 28 dias de suspensão da irrigação. O delineamento utilizado foi o inteiramente casualizado em arranjo fatorial 7 × 4 com quatro repetições. Foram avaliados o número de perfilhos, altura da planta, comprimento da lâmina foliar, número de folhas verdes por perfilho e número de folhas mortas por perfilho. O fator clone afetou significativamente o número de perfilhos por vaso e o número de folhas mortas por perfilho (P≤0,05). O clone de Sergipe produziu mais perfilhos (8.39) que os demais após 28 dias de interrupção da irrigação, enquanto a cultivar 'Mombaça' apresentou mais folhas mortas (5.39) após 7 dias sem irrigação. Em geral, a interrupção da irrigação por 28 dias resultou em plantas mais altas com lâminas foliares maiores e com número superior de folhas verdes por perfilho.

This study aimed to evaluate the morphological characteristics of Panicum maximum clones during the regrowth period following cessation of irrigation. Panicum clones were collected in Sergipe and in three Pernambuco locations (‘São Bento do Una’, ‘Itambé’ and ‘São João da Coroa Grande’), in addition to ‘Mombaça’, ‘Tanzânia’ and ‘Massai’ cultivars. The treatments consisted of seven clones, which were subjected to either 7, 14, 21 or 28 days of water suspension. The experimental design was completely randomized in a factorial 7 × 4 design, with four replicates. The morphological characteristics evaluated included the number of tillers, plant height, leaf blade length, number of green leaves per tiller and number of dead leaves per tiller. The clone factor significantly affected the number of tillers per pot and the number of dead leaves per tiller (P ≤ 0.05). The clone from Sergipe produced a greater number of tillers (8.39) than the other clones following 28 days of water suspension, while the ‘Mombaça’ cultivar had a greater number of dead leaves (5.39) after 7 days of water suspension. In general, the 28-day cessation of irrigation period resulted in taller plants with larger leaf blades and a greater number of green leaves per tiller.

Como não foi achado artigo relevante para o texto sobre o assunto de interesse nos últimos 5 anos, a busca foi estendida por mais 5 anos, e assim por diante, de acordo com a necessidade dos autores. Resultados: Literatura relevante foi encontrada com relação ao uso dos anti-histamínicos, antileucotrienos e corticosteroides orais nessas afecções. A Academia Brasileira de Rinologia ressalta, após amplo debate do colegiado, pontos-chave no tratamento com esses medicamentos. Conclusão: Há respaldo na literatura para o uso desses medicamentos, entretanto considerações finais acerca do papel de cada deles foram feitas.

Abstract Introduction: Inflammatory conditions of the nose and paranasal sinuses are very prevalent in the general population, resulting in marked loss of quality of life in affected patients, as well as significant work, leisure, and social activity losses. These patients require specific and specialized treatment. A wide range of oral medications are available. Objective: The present document is aimed to clarify, for professionals treating patients with inflammatory sinonasal diseases, both specialists and general practitioners, specific oral therapies in noninfectious nasal inflammatory conditions. Methods: The methodology used to create this article included the search for the key words: oral corticosteroids, antihistamines, antileukotrienes, rhinitis, rhinosinusitis in the MEDLINE and EMBASE databases in the last 5 years. Since no relevant article was found for the text on the subject of interest in the last 5 years, the search was extended for another 5 years, and so on, according to the authors’ needs. Results: Relevant literature was found regarding the use of antihistamines, antileukotrienes and oral corticosteroids in these conditions. The Brazilian Academy of Rhinology emphasizes, after extensive discussion by the collegiate, key points in the treatment with these drugs. Conclusion: There is support in the literature for the use of these drugs; however, final considerations about the role of each of them have been made.
