Abstract In the present study, a cost-effective and eco-friendly approach is being explored to remove the harmful dye Congo red from synthetic wastewater, using an equatorial strain of Rhodococcus biphenylivorans. The immobilized cells’ Congo red-decolorizing activity in calcium alginate showed an increase of 217% compared to the free cells. By improving the alginate concentration to 4% (w/v), the bead diameter to 3 mm and using 50 beads, a 67% decrease in the time required for complete decolorization was accomplished. Both free and immobilized cells followed first-order kinetics for the elimination of Congo red, with immobilized cells displaying a decolorization rate 3.2 times greater than that of free cells, resulting in an 84% reduction in half-life. The immobilized cells displayed the capability to remove 0.10 g/L Congo red without any significant decline in their efficiency for up to twelve cycles, offering an economic advantage due to their reusability. Examining the decolorized products of Congo red showed no hindrance in the germination of Triticum aestivum and Vigna radiata, indicating the effective removal of all toxic components from the original dye via the biological method. Therefore, this strain has significant potential as a biological agent to eliminate wastewater contaminated with Congo red efficiently.

This work evaluated the use of corncob as a support for the immobilization of an extracellular fructosyltransferase (E.C. 2.4.1.9) from Aspergillus oryzae IPT-301, aiming at the synthesis of a stable biocatalyst for the production of fructooligosaccharides. The transfructosylation activity of the immobilized enzyme was maximized via experimental design. Additionally, the biochemical properties and stability of the immobilized enzyme, as well as the reaction kinetics, were determined. The enzyme immobilized on alkali-treated corncob showed the highest transfructosylation activity at 50 °C and pH 5.5. It also presented a wide pH stability and a half-life around 1.4 times greater than the soluble enzyme. Furthermore, the immobilized enzyme showed 53% of retention of catalytic activity in a second consecutive reaction cycle, showing the potential for reuse. These results suggest that alkali-treated corncob is a promising support material for the synthesis of heterogeneous biocatalysts aiming at fructooligosaccharide production, which can contribute to the valorization of this abundant agro-waste.

Resumo Olodo têxtil é um resíduo do tratamento do efluente das lavanderias têxteis e sua incorporação em materiais alternativos tem sido proposta como possibilidade para sua destinação. Foi realizada uma busca sistemática na literatura nesta perspectiva, visando observar as concentrações de material residual e seu preparo, as matrizes utilizadas, o desempenho tecnológico e imobilização do resíduo têxtil. As matrizes empregadas foram argamassas, concretos e tijolos cerâmicos, sendo observados, de maneira geral, efeitos deletérios nas características mecânicas dos materiais produzidos. Em concretos e argamassas, a finura impactou no aumento da demanda de água, o que elevou a porosidade das misturas; e a matéria orgânica e metais pesados, na hidratação do cimento. Estudos recentes propuseram, então, o pré-tratamento do material residual como uma alternativa favorável. Incrementos na porosidade também ocorreram nos tijolos cerâmicos, porém, devido ao elevado teor de matéria orgânica. Quanto a imobilização do resíduo, os materiais cimentícios apresentaram desempenho satisfatório; já os tijolos cerâmicos, obtiveram alguns resultados fora dos limites normativos. Portanto, é necessário ampliar as discussões quanto ao pré-tratamento realizado no lodo têxtil, bem como seus impactos no desempenho mecânico e ambiental. destinação perspectiva preparo utilizadas argamassas cerâmicos observados geral produzidos água misturas pesados cimento propuseram então prétratamento pré favorável porém satisfatório normativos Portanto ambiental

Abstract Textile sludge is a waste from the effluent treatment of textile laundries and its incorporation into alternative materials has been proposed as a possibility for its disposal. A systematic search was carried out in literature from this perspective, aiming to observe concentrations of waste material and its preparation, matrices used, technological performance and immobilization of textile waste. The matrices used were mortars, concretes and ceramic bricks, in general, deleterious effects were observed on mechanical characteristics of the materials produced. In concrete and mortars, the fineness had an impact on increase in water demand, which increased mixtures porosity; and organic matter and heavy metals, in cement hydration. Recent studies therefore proposed waste material pre-treatment as a favorable alternative. Increases in porosity also occurred in ceramic bricks, however, due to high organic matter content. Regarding waste immobilization, cementitious materials showed satisfactory performance; ceramic bricks, on the other hand, obtained some results outside the normative limits. Therefore, it is necessary to expand discussions regarding the pre-treatment carried out on textile sludge, as well as its impacts on mechanical and environmental performance. disposal perspective preparation mortars bricks general produced demand metals hydration pretreatment pre however content hand limits Therefore

Resumen La luxación de rodilla es la pérdida de la relación articular femorotibial, asociada a lesiones de mínimo dos ligamentos mayores; ocurre en el 0,02 % de lesiones en ortopedia. El objetivo de este artículo es presentar el caso de una paciente adulta intermedia con obesidad grado I, quien presentó caída desde su altura, con trauma en rodilla derecha. La radiografía de ingreso evidenció luxación anteromedial en esta articulación, por lo cual es llevada a reducción cerrada e inmovilización y, posteriormente, se realiza radiografía posreducción, Doppler arteriovenoso y resonancia magnética encontrando desgarro del menisco lateral, ruptura de los ligamentos cruzado posterior, cruzado anterior, retináculo lateral y fractura de la cabeza del peroné. Este caso es significativo al tratarse de una luxación en trauma de ultra baja energía en un paciente con obesidad, que no es la presentación típica y resalta la importancia de la búsqueda activa de lesiones asociadas.

Abstract Knee dislocation is the loss of the femorotibial joint relationship associated with injuries to at least two major ligaments and occurs in 0,02 % of injuries in orthopedics. The objective of this article is to present the case of an intermediate adult patient with grade I obesity, who fell from her height with trauma to the right knee. The admission x-ray showed ante-romedial dislocation in this joint, which is why she underwent reduction. closed and immobilization and subsequently a post-reduction radiography, arteriovenous Doppler and magnetic resonance imaging were performed, finding a tear of the lateral meniscus, rupture of the posterior cruciate ligaments, anterior cruciate ligament, lateral retinaculum and fracture of the head of the fibula. This case is significant as it is a dislocation in ultra-low energy trauma, in a patient with obesity, which is not the typical presentation and highlights the importance of actively searching for associated injuries.

Abstract This study performed LSV simulation of two-step irreversible electron oxidation with the intermediate (E↓E), which was immobilized on the electrode surface. The response exhibited either one or two peaks, depending on the intermediate stability. The first electron transfer depended on the reactant diffusion, while the second one was a function of the accumulated intermediate. For this reason, the second Ip was higher than the first one, and the single peak split into two peaks, under the influence of an increased SR. Thermodynamic and kinetic parameters influence on the two components of the response were analyzed.

Resumen Los pesticidas sintéticos utilizados para combatir las garrapatas pierden su eficacia contra determinadas especies y pueden afectar la salud humana. En el presente estudio se evaluó in vitro e in vivo el efecto del extracto acuoso de semillas de Pimpinella anisum (P. anisum) contra Rhipicephalus sanguineus e Ixodes affinis, garrapatas del perro doméstico. En las evaluaciones in vitro se aplicaron directamente a las garrapatas concentraciones de 1.25, 2.5, 5, 10, 25, 50, 75 y 100 % del extracto acuoso de P. anisum. Las concentraciones que provocaron mayor efectividad en la inmovilización fueron 50%, 75% y 100%, pero esta última provocó una inmovilización por mayor tiempo (55.89 ± 0.16 min). En la evaluación in vivo, el extracto acuoso concentrado se aplicó sobre garrapatas adheridas a la piel de perros domésticos. Se utilizó Amitraz, un garrapaticida comercial, como testigo positivo. Tanto el extracto acuoso concentrado como el Amitraz provocaron el 100 % del desprendimiento de garrapatas. Sin embargo, el extracto acuoso concentrado de semillas de P. anisum fue más efectivo para reducir el tiempo promedio de desprendimiento de las garrapatas (60.81 ± 3.17 min) en comparación con el garrapaticida comercial Amitraz (145.12 ± 15.97 min). Esta investigación sugiere que el p-anisaldehído identificado en el extracto acuoso podría estar relacionado con la inmovilización y desprendimiento de R. sanguineus e I. affinis de los perros domésticos, lo que sugiere que este extracto podría usarse como biopesticida para controlar las garrapatas en perros domésticos.

Abstract Synthetic pesticides used to combat ticks lose their effectiveness against certain species and can affect human health. The present study evaluated in vitro and in vivo the effect of the aqueous extract of Pimpinella anisum (P. anisum) seeds against Rhipicephalus sanguineus and Ixodes affinis, domestic dog ticks. In the in vitro evaluations, concentrations of 1.25, 2.5, 5, 10, 25, 50, 75 and 100 % of the aqueous extract of P. anisum were applied directly to ticks. The concentrations that had the highest effectiveness in immobilization were 50 %, 75 % and 100 %, but the latter caused immobilization for a longer time (55.89 ± 0.16 min). In the in vivo evaluation, the concentrated aqueous extract was applied to ticks attached to the skin of domestic dogs. Amitraz, a commercial tickicide, was used as a positive control. Both the concentrated aqueous extract and Amitraz caused 100 % of tick detaching. Nonetheless, concentrated aqueous extract of P. anisum seeds was more effective in reducing the average time of tick detaching (60.81 ± 3.17 min) compared to the commercial tickicide Amitraz (145.12 ± 15.97 min). This research suggests that the p-anisaldehyde identified in the aqueous extract could be linked to the immobilization and detaching of R. sanguineus and I. affinis from domestic dogs, suggesting that this extract could be used as a biopesticide to control ticks in domestic dogs.

In this work, some of the synthesis methods already reported for aluminum(III) hydroxide polymorphs with layered structure like gibbsite are revisited. Gibbsite was synthesized with high purity and yield by a simple route developed from modifications of a heating method proposed in the literature, making it possible to prepare gibbsite in regular glassware, avoiding the use of hydrothermal reactor and oven, as described in the literature. The proposed synthesis was conducted with a heating system under reflux conditions in a glass heating flask, using an oil bath, without the need for more sophisticated equipment. This is an accessible alternative method for crystalline gibbsite synthesis, with yield (76 wt.%). The obtained gibbsite was used as a precursor for the synthesis of a lithium/aluminum layered double hydroxide (LDH) from the intercalation method of Al(OH)3 in aqueous solution of lithium chloride. Gibbsite and the obtained LDH Li/Al were used for the immobilization of an anionic porphyrin with a loading on the order of 10-5 mol g-1 of solid, thus being alternative solid supports for catalytic species such as porphyrins.

Abstract This article results from a qualitative, cross-sectional, descriptive study based on a historical-dialectical approach. It aimed to understand aspects of the school trajectory and the perspectives of students and graduates regarding their expectations of high school technical training in health in the neoliberal scenario. Data was collected through four focus groups with students and graduates from four technical courses in the health area - clinical analysis, nursing, orthopedic immobilization, and radiology - from two public and two private technical schools in Mato Grosso do Sul, Brazil. Content analysis guided the data analysis. The school trajectory and expectations of students and graduates for technical training are in line with the problems faced by Brazilian youth and the ideals of neoliberal society, which prioritizes training for the working class in terms of employability, which rules out the possibility of dense training - which would allow for social insertion with criticality and better conditions for understanding the relationship between health and society. However, it is in the midst of the contradictions of this society that the school can contribute to overcoming class society in favor of the emancipation of the working class. qualitative crosssectional, crosssectional cross sectional, sectional cross-sectional historicaldialectical historical dialectical approach scenario nursing immobilization Sul Brazil employability However

Resumo A patela baixa é uma patologia do joelho pouco frequente, mas limitante devido à rigidez articular e dor localizada na região anterior do joelho. Pode decorrer após trauma, imobilização prolongada ou intervenção cirúrgica local. O achado patológico marcante é o encurtamento e o aumento na espessura do ligamento patelar. Foram descritas várias técnicas cirúrgicas para o seu tratamento, não existindo nenhum tratamento padronizado. Descrevemos o caso de uma doente de 73 anos de idade que apresentava rigidez do joelho, deficit funcional importante e patela baixa após artroplastia total do joelho. Foi submetida a um procedimento cirúrgico de partes moles recentemente descrito, com excelente evolução funcional, melhorando de um Lysholm Knee Score de 16 para 81 pontos, permitindo a mobilização e regresso às atividades de vida diárias precocemente. frequente trauma local patelar padronizado 7 descrito 1 8 pontos precocemente

Abstract Patella baja is an infrequent knee pathology, but it is limiting due to joint stiffness and localized pain in the anterior region of the knee. It may occur after trauma, prolonged immobilization or local surgical intervention. The striking pathological finding is the shortening and increase in thickness of the patellar ligament. Several surgical techniques have been described for its treatment, and there is no standardized treatment. We describe the case of a 73-year-old female patient who presented with knee stiffness, significant functional deficit, and patella baja after total knee arthroplasty. She underwent a recently described soft tissue surgical procedure, with excellent functional evolution, improving from a Lysholm Knee Score of 16 to 81 points, allowing early mobilization and return to daily life activities. pathology trauma intervention ligament treatment 73yearold yearold 73 year old deficit arthroplasty procedure evolution 1 8 points activities 7

Resumo Objetivo A neuropatia compressiva mais comum dos membros superiores é a síndrome do túnel do carpo (STC). Historicamente, houve uma tendência à aplicação de imobilização no pós-operatório, prática que tem diminuído nos últimos anos. O objetivo desta revisão é avaliar se existem evidências científicas que justifiquem o uso da imobilização nos cuidados pós-operatórios de descompressão da STC. Métodos Foram utilizadas as seguintes bases de dados: Biblioteca Virtual em Saúde (BVS), PubMed National Library of Medicine (NLM), Cochrane Library, Scientific Electronic Library Online (SciELO), e EMBASE. Foram utilizados os seguintes critérios de inclusão: 1) discussão do pós-operatório de cirurgias de descompressão do nervo mediano na STC; 2) comparação dos resultados, após descompressão cirúrgica, na STC entre imobilização do punho ou apenas curativo local; 3) todos os idiomas, independentemente do ano de publicação; e 4) todos os tipos de publicações. Foram utilizados os seguintes critérios de exclusão: 1) estudos que não avaliaram o pós-operatório de descompressão da STC; 2) falta de avaliação do resultado relacionado à conduta de aplicação de curativo local e/ou alguma forma de imobilização do punho após o procedimento cirúrgico de descompressão; e 3) publicações repetidas Resultados A busca bibliográfica resultou em 336 publicações relevantes. Ao final, foram escolhidas 18 publicações. Foram encontradas revisões sistemáticas, ensaios clínicos randomizados e estudos transversais. Conclusões Devido à escassez de evidências que apoiem o uso da imobilização, associada aos custos mais elevados relacionados com a prática, nas últimas décadas, essa tem se tornado cada vez menos frequente. Relevância clínica Na literatura há descrições de duas abordagens nos cuidados pós-operatórios de descompressão da STC: imobilização ou apenas curativo local. Vale a pena avaliar qual é a melhor entre as duas de acordo com as evidências científicas disponíveis. .

Abstract Objective The most common compressive neuropathy of the upper limbs is carpal tunnel syndrome (CTS). Historically, there has been a tendency to apply immobilization in the postoperative period, a practice that has decreased in recent years. This review aims to assess whether there is scientific evidence to justify the use of immobilization in the postoperative care of CTS decompression. Methods The following databases were used: Biblioteca Virtual em Saúde (BVS), PubMed National Library of Medicine – (NLM), Cochrane Library, Scientific Electronic Library Online (SciELO), and EMBASE. The following inclusion criteria were used: 1) discussion of the postoperative period of median nerve decompression surgery in CTS; 2) comparison of results after surgical decompression in CTS between wrist immobilization or local dressing; 3) all languages, regardless of the year of publication; and 4) all types of publications. The following exclusion criteria were used: 1) studies that did not evaluate the postoperative period of CTS decompression; 2) lack of evaluation of the outcome related to the application of local dressing or some form of wrist immobilization after the surgical decompression procedure; and 3) repeated publications. Results The literature search resulted in 336 relevant publications. In the end, 18 publications were chosen. Systematic reviews, randomized clinical trials, and cross-sectional studies were found. Conclusions Due to the scarcity of evidence supporting the use of immobilization coupled with the higher costs associated with the practice, it has become less and less frequent in recent decades. Clinical relevance In the literature, two approaches to postoperative care for CTS decompression are described: immobilization or just local dressing. According to the available scientific evidence, it is worth evaluating which one is better. CTS. .

In recent years, various methods for surface functionalization of magnetite nanoparticles with emerging modifications have been explored and reported. Green nano-chemistry aims to synthesize nanomaterials using bio-based resources, providing new materials for biological and environmental applications. Surface modification of magnetite nanoparticles using phytochemicals extracted from plants is a fundamental principle of green synthesis routes. Agricultural waste from different crops, such as plantain pseudostem, is of particular interest as a renewable resource due to its abundant availability, low toxicity, and economic feasibility. In this study, the juice extracted from plantain pseudostem was utilized for the phytofunctionalization of magnetite nanoparticles. Characterization techniques including transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and fourier-transform infrared spectroscopy (FTIR) confirmed the nanometric dimensions of the composite (size range of 12.6 ± 3.17 nm) and established its organic-inorganic nature. The superparamagnetic properties of the composite were also demonstrated. Moreover, the potential application of this nanohybrid in bioremediation for the immobilization of cadmium(II) and lead(II) showed promising results, highlighting its efficacy in managing water pollutants. years reported nanochemistry nano chemistry biobased bio based resources applications routes crops availability toxicity feasibility study TEM, TEM , (TEM) SEM, SEM (SEM) TGA, TGA (TGA) fouriertransform fourier transform FTIR (FTIR size 126 12 6 12. 317 3 17 3.1 nm organicinorganic organic inorganic nature demonstrated Moreover cadmiumII cadmium II cadmium(II leadII lead lead(II results pollutants (TEM (SEM (TGA 1 31 3.

Photosynthetic microorganisms have been widely studied as an alternative technology for CO2 capture. Aiming to overcome some operational challenges in the application of these microorganisms for gas treatment on a large scale, the immobilization of microalgae in solid matrices emerges as an alternative to facilitate effective management of microalgae culture during harvesting process. In this work, different matrices for microalgae immobilization composed of silica/alginate were obtained varying silica precursors. The synthesized materials were characterized in terms of their specific surface area, cell viability, transparency and physical-chemical properties. Additionally, a new methodology was developed to evaluate the CO2 capture by microalgae using a pressurized system with natural gas mixture. Tests were carried out exploring the influence of some variables, such as headspace volume, cell concentration, stirring and pressure. Once the optimized parameters were established, the amount of CO2 captured by immobilized microalgae was investigated for 7 days by determining the CO2 relative concentrations using gas chromatography. The results of immobilized microalgae showed levels of CO2 removal of 41.4%. This work proved the potential application of the studied biomaterial for natural gas processing, making even more feasible the adoption of this technology for selective capture of CO2 on an industrial scale.

This work explores the possibility of using corn cob powder as a carrier for immobilization by physical adsorption of lipase from Rhizopus oryzae used in acidolysis reaction of grape seed oil with capric acid (C10) to synthesize dietary triglycerides (TAGs) formed from medium-long-medium chain (MLM) fatty acids in a fixed bed reactor. First, enzymatic loading was investigated to improve hydrolytic activity and the immobilized biocatalyst was characterized in terms of biochemical parameters and thermal stability. An enzyme load of 30 mg mL-1 was quite adequate, as about 90% of the immobilization yield was achieved. The central composite rotatable design (CCRD) experimental design revealed that, for the immobilized enzyme, the optimal hydrolytic activity was obtained at pH 7.75 and 41 °C. Stirred tank reactions were optimized in CCRD statistical analysis revealing the most desirable conditions for molar ratio of 1:9.36 (oil:acid), 45 °C and 15% biocatalyst, obtaining a maximum ID value of 86.93 ± 2.25%. In a fixed bed reactor, the synthesis showed an average ID of 51.13 ± 0.77, demonstrating the potential of this configuration. It is concluded that corn cob powder as an immobilization carrier is a promising alternative for the enzymatic synthesis of MLM triacylglycerols.
