Abstract The characterization of clones is a very important step in genetic certification programs, as it describes and recognizes the plant material at every stage of production, allowing the monitoring of genetic quality, improvement and conservation of the germplasm. The aim of this work was to morphologically characterize two elite banana clones. The experimental design applied was in randomized blocks, with four replications, with six plants per parcel. The treatments consisted of two elite banana clones, Prata Gorutuba R1 and Prata Gorutuba R2 and four commercial cultivars: Prata Gorutuba, Prata Ana, Grande Naine and BRS Princesa. The morphological characterization was carried out in the second production cycle (daughter plant), using 23 qualitative descriptors, visually evaluated, classified according to the instructions for carrying out the distinguishability, homogeneity and stability (DHS) tests of banana cultivars. The elite clones Prata Gorutuba R1 and R2 differed from the cultivars Grande Naine and BRS Princesa regarding the descriptors tapering of the pseudostem, predominant color of the pseudostem, intensity of anthocyanin coloration and color of the underside of the basal sheath. The descriptors made it possible to group elite clones into the Prata group, a group that predominates in crops in Brazil, with characteristics already widely accepted by the market.

Resumo A caracterização dos clones é uma etapa de suma importância em programas de certificação genética, pois descreve e reconhece o material vegetal em toda etapa de produção, permitindo o monitoramento da qualidade genética, o melhoramento e a conservação do germoplasma. Objetivou-se com este trabalho caracterizar, morfologicamente, dois clones-elites de bananeira. O delineamento utilizado foi em blocos ao acaso, com quatro repetições, sendo seis plantas úteis. Os tratamentos foram compostos por dois clones-elites de bananeira Prata Gorutuba R1 e Prata Gorutuba R2 e quatro cultivares comerciais: Prata Gorutuba, Prata-Anã,Grande Naine e BRS Princesa. A caracterização morfológica foi realizada no segundo ciclo de produção (planta-filha), utilizando 23 descritores qualitativos, avaliados visualmente, classificados de acordo com as instruções para execução dos ensaios de distinguibilidade,homogeneidade e estabilidade (DHE) de cultivares de bananeira. Os clones-elites Prata Gorutuba R1 e R2 diferiram das cultivares Grande Naine e BRS Princesa referente aos descritores afunilamento do pseudocaule, cor predominante do pseudocaule, intensidade da coloração antocianínica e cor da face inferior da bainha basal. Os descritorespossibilitaram agrupar os clones-elites no grupo Prata, grupo este predominante em cultivos no Brasil,com características já amplamente aceitas pelo mercado.

Abstract The evaluation of new banana genotypes with agronomic potential and tolerant to the main pests and diseases is essential for the market. The objective was to evaluate the vegetative and productive characteristics of new potential banana clones, such as ‘Prata Gorutuba R1’ and ‘Prata Gorutuba R2’ and commercial cultivars. The experiment was implemented in a rural property located in the municipality of Nova Porteirinha, MG. The treatments consisted of ‘Prata Gorutuba R1’ and ‘Prata Gorutuba R2’ banana clones (genotypes selected from the ‘Prata Anã’ clone ‘Gorutuba’ tolerant to Panama disease) and four cultivars: ‘Prata Gorutuba’, ‘Prata Anã’, ‘Grande Naine’ and ‘BRS Princesa’. The treatments were distributed in randomized blocks, with four replications and six useful plants per plot. The planting spacing used was 3.5 m x 1.7 m. The evaluations were carried out in the first and second production cycles. The ‘Prata Gorutuba R1’ and’ Prata Gorutuba R2’ clones in general showed excellent performance compared to the already consolidated cultivars. The clones presented median height and number of leaves in the ideal flowering for banana trees of the ‘Prata’ subgroup. Bunch and bunch weight, as well as production were similar to the ‘Prata Anã’, ‘Prata Gorutuba’ and ‘BRS Princesa’ cultivars. Considering that the clones evaluated present high tolerance to Fusarium wilt, the result indicates that the materials have great potential for the registration of new cultivars.

Resumo Avaliação de novos genótipos de bananeira com potencial agronômico e tolerantes às principais pragas e doenças é essencial para o mercado. Objetivou-se avaliar as características vegetativas e produtivas dos novos potenciais clones-elites de bananeira ‘Prata Gorutuba R1’ e ‘Prata Gorutuba R2’ e de cultivares comerciais. O experimento foi implantado em propriedade no município de Nova Porteirinha-MG. Os tratamentos consistiram nos clones-elites de bananeira ‘Prata Gorutuba R1’ e ‘Prata Gorutuba R2’ (tolerantes à murcha de Fusarium) e das cultivares: ‘PrataGorutuba’, ‘Prata-Anã’, ‘Grande Naine’ e ‘BRS Princesa’. Os tratamentos foram distribuídos emblocos ao acaso,com quatro repetições e seis plantas úteis por parcela. As avaliações foramrealizadas no primeiro e segundo ciclos de produção. Os clones-elites ‘Prata Gorutuba R1’e ‘Prata Gorutuba R2’ apresentaram excelente desempenho, comparados às cultivares jáconsolidadas no mercado. Os clones-elites apresentaram altura de planta considerada mediana e número de folhas no florescimento ideal para bananeiras do subgrupo ‘Prata’. Peso decacho e de pencas, e produção foram semelhantes às cultivares ‘Prata-Anã’, ‘Prata Gorutuba’ e ‘BRS Princesa’. Considerando que os clones avaliados apresentam elevada tolerânciaà murcha de Fusarium, o resultado sugere que os materiais apresentam grande potencialpara o registro de novas cultivares.

Resumo Por meio de uma análise panorâmica da presença da dança no cinema, desde os primórdios até a produção contemporânea, percebemos que ela pode emergir ora como parte integrante e estruturante do filme, no gênero musical, ora como um elemento contrastante e disruptivo, em filmes não musicais. Ao esboçarmos uma estética da movimentação dos corpos em obras audiovisuais, partimos do pressuposto de que o cinema sonoro de certo modo silencia a dinâmica corporal na tela ao concentrar seu foco na fala e no sentido das palavras, eliminando ou reduzindo consideravelmente toda a potência (plástica, mas também semântica) contida na incrível retórica expressiva dos corpos. Será que a dança, abrigo natural de certa pulsão gestual irracional, pode servir, como propunha Béla Balázs, para que sejamos atingidos por um filme de maneira direta e inequívoca, como se fosse uma música? contemporânea musical disruptivo musicais audiovisuais palavras plástica, plástica (plástica semântica irracional servir Balázs inequívoca música

Abstract Through a panoramic analysis of the presence of dance in cinema, from the beginning to the contemporary production, we realize that it can emerge sometimes as an integral and structuring part of the film, in the musical genre, and sometimes as a contrasting and disruptive element, in non-musical films. While sketching an aesthetic of corporeal movements in audiovisual works, we assume that sound cinema, in a way, silences the body dynamics on the screen, by focusing on speech and the meaning of words, eliminating or considerably reducing all the visual and semantic powers contained in the incredible expressive rhetoric of bodies. Can dance, the natural shelter of a certain irrational gestural impulse, serve, as Béla Balázs proposed, to make us be affected by a film in a direct and unequivocal way, as if it were music? cinema production genre element nonmusical non films works way screen words bodies impulse serve proposed music

Abstract Dynamic soil parameters such as the shear modulus suffer degradation while damping in soil increases under dynamic loading. These can be determined from various tests such as element tests, field tests and centrifuge experiments. Most of the studies about dynamic soil characterization have focused on evaluating these parameters assuming horizontal ground conditions without considering the effect of static shear stresses induced by ground inclination. This paper presents a dynamic centrifuge test conducted on a layered gentle slope comprising clay and sand, to obtain experimental data in terms of shear modulus and damping for various shear strains. Particle Image Velocimetry (PIV) was employed to measure the displacements and to calculate accelerations due to seismic loading at various depths throughout the slope model. The results suggest that the static shear stress caused by the profile inclination causes a more pronounced degradation of the shear modulus when compared to flat ground conditions. Moreover, the damping during the centrifuge test exhibited larger values than expected, following a similar behavior observed in other experimental programs. The strain rate analysis revealed the mobilization of shear stresses higher than the monotonic shear strength for the clay layers during the seismic shaking. experiments sand strains PIV (PIV model Moreover expected programs shaking

ABSTRACT During recent decades systematic archaeological studies have been carried out in the Salado creek basin (Lamadrid county, Interhills area, Buenos Aires province). However, potsherds are one of the material items that have not yet been studied in detail due to their scarcity and high fragmentation at the local level. This work presents the first results of the macroscopic and microscopic analysis of the ceramic assemblage from the Hangar site, dated to the final Late Holocene. By evaluating the technical choices, vessels with simple morphologies and smooth surfaces were identified. Compositionally, two types of pastes were distinguished that account for the preparation and use of different raw materials for the production of the vessels. Finally, it is discussed whether this technology was produced locally or was obtained through interactions with neighboring groups.

RESUMEN En las últimas décadas se desarrollaron estudios arqueológicos sistemáticos en la cuenca del arroyo Salado (partido de Lamadrid, área Interserrana, provincia de Buenos Aires). No obstante, los restos de alfarería son uno de los ítems materiales que aún no había sido estudiado en detalle debido a su escasez y alta fragmentación a nivel local. En este trabajo se presentan los primeros resultados del análisis macro y microscópico realizado al conjunto cerámico procedente del sitio Hangar, para el cual se cuenta con dos fechados que lo sitúan cronológicamente en el Holoceno tardío final. Mediante la evaluación de las elecciones técnicas se identificaron vasijas de morfologías simples y superficies alisadas. Composicionalmente se distinguen dos tipos de pastas que dan cuenta de la preparación y uso de diferentes materias primas para la producción de las piezas. Finalmente, se discute si esta tecnología fue manufacturada localmente o fue obtenida por interacciones con grupos vecinos.

Abstract Germination increases total phenolic compounds (TF) concentration and antioxidant activity (AOx). The characterization and quantification of TPC, total flavonoids content (TPC), and AOx of beans (Phaseolus vulgaris) and peas (Pisum sativum) sprouts, germinated for ten days was performed. Results showed that the highest concentration of TPC for both sprouts was in days 6 and 7 (685.21 and 910.69 mg GAE/100 g dry matter) and TF varied only for beans. AOx of the pea sprouts was 512.64 and 6083.55 mg ET/100 g dry matter to DPPH and ORAC method, respectively, is higher than for bean. Regarding FRAP, bean sprouts showed better values (421.07 mg ET/100 g dry matter) compared to pea; in the CUPRAC analysis, sprouted bean showed better activity than a pea (85.76 and 44.05% inhibition). Germination induced variations in gallic and syringic acids in pea sprouts and of catechin and quercetin in the bean. Germination time and legume type are important factors the biological activity of sprouts.

Resumen Brasil se encuentra en una región intra-placa de baja a moderada sismicidad, esto quiere decir que hay una limitada disponibilidad de registros de acelerogramas representativos de la región. Parte de un estudio de respuesta local o del diseño sísmico de estructuras requiere del uso de registros aceleración-tiempo que sean compatibles con un espectro de diseño. El presente trabajo tiene como objetivo la aplicación de metodologías para obtener acelerogramas representativos de la región sudeste brasilera, en particular en la región offshore de la cuenca de Campos. Se utilizó la información del análisis probabilístico del riesgo sísmico desarrollado para la región de interés en este estudio para obtener el espectro de respuesta de diseño y para definir los escenarios sísmicos que generan mayor influencia. Adicionalmente, se utilizó la información de acelerogramas registrados a partir de dos sismos relativamente recientes ocurridos en la región sudeste brasilera, para la aplicación de una de las metodologías de obtención de acelerogramas sintéticos.

Abstract Brazil is in an intraplate area of low to moderate seismicity, this means that few or no records of strong ground motions are available. Part of the site response analysis and seismic design of structures require the use of acceleration time-histories compatible with a specified target response spectrum. This study aims to utilize methodologies based on the use of existing earthquake records from a well-known database and synthetic accelerograms to obtain ground motions representative of the Brazilian Southeast Region, particularly in the offshore Campos Basin. Information from a probabilistic seismic hazard assessment performed in the interest area was employed as input to the methodologies applied in terms of target response spectrum and the dominant earthquake scenarios. Besides, the acceleration time-histories of two relatively recent earthquakes that occurred in the Brazilian Southeast were used to apply one of the approaches to obtain a synthetic spectrum compatible accelerogram.

Abstract: En | Text: En | PDF: En

Hippeastrum puniceum is a species that belongs to the Amaryllidaceae family. A particular characteristic of this family is the consistent and very specific presence of isoquinoline alkaloids, which have demonstrated a wide range of biological activities such as antioxidant, antiviral, antifungal, antiparasitic, and acetylcholinesterase inhibitory activity, among others. In the present work, fifteen alkaloids were identified from the bulbs of Hippeastrum puniceum (Lam.) Kuntz using a GC-MS approach. The alkaloids 9-O-demethyllycoramine, 9-demethyl-2α-hydroxyhomolycorine, lycorine and tazettine were isolated through chromatographic techniques. The typical Amaryllidaceae alkaloids lycorine and tazettine, along with the crude and ethyl acetate extract from bulbs of the species were evaluated for their inhibitory potential on α-amylase, α-glucosidase, tyrosinase and acetylcholinesterase activity. Although no significant inhibition activity was observed against α-amylase, α-glucosidase and tyrosinase from the tested samples, the crude and ethyl acetate extracts showed remarkable acetylcholinesterase inhibitory activity. The biological activity results that correlated to the alkaloid chemical profile by GC-MS are discussed herein. Therefore, this study contributed to the knowledge of the chemical and biological properties of Hippeastrum puniceum (Lam.) and can subsidize future studies of this species.

Resumo Objetivo Apresentar o resultado das avaliações radiográficas dos pacientes com fraturas extra-articulares do rádio distal submetidos a fixação percutânea com parafuso maciço de 3.5mm. Métodos Série de casos, analítica, descritiva e retrospectiva de 16 pacientes com avaliação dos parâmetros radiográficos da técnica utilizada. Resultados A média de idade da população estudada foi de 46,5 anos (25–60 anos), sendo 81,25% do sexo feminino. O tempo de espera até a cirurgia foi de 8,8 dias (4–14 dias). O tilt volar médio pré-procedimento foi - 7,41° (−23,48°–5,29°, desvio padrão [DP] ± 6,59°). O tilt volar imediatamente após o procedimento cirúrgico foi de 5,93° (DP ± 6,23°, p< 0,001). Sem diferença estatística nos valores de tilt volar ao final de 6 meses de evolução. A altura radial pré-procedimento foi de 4,13 mm (−7,8°–9,5°, DP ± 5,06°). Aumento estatisticamente significativo no pós-operatório imediato para 10,04 mm (p= 0,002). Redução significativa ao final de 6 meses para 9,55 mm (p= 0,012). Atingimos 100% de consolidação com a técnica utilizada, com índice mínimo de complicações. Nenhum paciente apresentou infecção ou precisou ser reoperado. Conclusão A técnica mostrou-se eficaz para o tratamento de fraturas extra-articulares da extremidade distal do rádio ao final de 6 meses, com baixo índice de complicações e parâmetros radiográficos aceitáveis e próximos dos valores anatômicos.

Abstract Objective The present paper aims to present results from radiographic evaluations of patients with extra-articular distal radius fractures submitted to percutaneous fixation with a 3.5 mm solid screw. Methods Analytical, descriptive and retrospective case series of 16 patients with evaluation of the radiographic parameters. Results The average age of the study population was 46.5 years old (25–60 years old); 81.25% of the sample was female. The average time until surgery was 8.8 days (4–14 days). The mean preprocedural volar tilt was - 7.41° (−23.48°–5.29°, standard deviation [SD] ± 6.59°). The mean volar tilt immediately after surgery was 5.93° (SD ± 6.23°, p< 0.001). There was no statistical difference in volar tilt values after 6 months of follow-up. The mean preprocedural radial height was 4.13 mm (−7.8 mm–9.5 mm, SD ± 5.06 mm). There was a statistically significant increase at the immediate postoperative period to 10.04 mm (p= 0.002), and a significant reduction at 6 months to 9.55 mm (p= 0.012). The consolidation rate was 100% with the technique used, with a minimal complication rate. No patient had infection or required a reoperation. Conclusion The technique was effective for the treatment of distal radial extra-articular fractures at 6 months, with a low complication rate; radiographic parameters values were acceptable and close to the anatomical ones.

Resumo Objetivo: Este estudo com acompanhamento de longo prazo visou a avaliar o quadro clínico, os achados laboratoriais, o perfil histológico, os tratamentos e os resultados de crianças e adolescentes com hepatite autoimune. Métodos: Foram analisados os prontuários médicos de 828 crianças e adolescentes com HAI. Foi usado um questionário para coletar os dados anônimos sobre o quadro clínico, os achados bioquímicos e histológicos e os tratamentos. Resultados: De todos os pacientes, 89,6% tinham hepatite autoimune-1 e 10,4% hepatite autoimune-2. O sexo feminino foi predominante nos dois grupos. A idade média no início dos sintomas foi 111,5 (6; 210) e 53,5 (8; 165) meses nos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente. Foi observado início clínico agudo em 56,1% e 58,8% e sintomas insidiosos em 43,9% e 41,2% dos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente. A probabilidade de insuficiência hepática foi 1,6 vezes maior para hepatite autoimune-2; 3,6% e 10,6% dos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente, apresentaram insuficiência hepática fulminante; o risco foi 3,1 vezes maior para hepatite autoimune-2. Os níveis de gamaglobulina e imunoglobulina G foram significativamente maiores nos pacientes com hepatite autoimune-1, ao passo que os níveis de imunoglobulina A e C3 foram menores em pacientes com hepatite autoimune-2; 22,4% dos pacientes apresentaram cirrose e a remissão bioquímica foi atingida em 76,2%. A taxa de sobrevida atuarial foi de 93,0%. Um total de 4,6% pacientes foram submetidos a transplante de fígado e 6,9% morreram (hepatite autoimune-1: 7,5%; hepatite autoimune-2: 2,4%). Conclusões: Nesta grande série clínica de crianças e adolescentes brasileiros, a hepatite autoimune-1 foi mais frequente e os pacientes com hepatite autoimune-2 mostraram maiores taxas de remissão da doença com respostas mais rápidas aos tratamentos. Os pacientes com hepatite autoimune-1 apresentaram maior risco de óbito.

Abstract Objective: This large study with a long-term follow-up aimed to evaluate the clinical presentation, laboratory findings, histological profile, treatments, and outcomes of children and adolescents with autoimmune hepatitis. Methods: The medical records of 828 children and adolescents with autoimmune hepatitis were reviewed. A questionnaire was used to collect anonymous data on clinical presentation, biochemical and histological findings, and treatments. Results: Of all patients, 89.6% had autoimmune hepatitis-1 and 10.4% had autoimmune hepatitis-2. The female sex was predominant in both groups. The median age at symptom onset was 111.5 (6; 210) and 53.5 (8; 165) months in the patients with autoimmune hepatitis 1 and autoimmune hepatitis-2, respectively. Acute clinical onset was observed in 56.1% and 58.8% and insidious symptoms in 43.9% and 41.2% of the patients with autoimmune hepatitis-1 and autoimmune hepatitis-2, respectively. The risk of hepatic failure was 1.6-fold higher for autoimmune hepatitis-2. Fulminant hepatic failure occurred in 3.6% and 10.6% of the patients with autoimmune hepatitis-1 and autoimmune hepatitis-2, respectively; the risk was 3.1-fold higher for autoimmune hepatitis-2. The gamma globulin and immunoglobulin G levels were significantly higher in autoimmune hepatitis-1, while the immunoglobulin A and C3 levels were lower in autoimmune hepatitis-2. Cirrhosis was observed in 22.4% of the patients; biochemical remission was achieved in 76.2%. The actuarial survival rate was 93.0%. A total of 4.6% underwent liver transplantation, and 6.9% died (autoimmune hepatitis-1: 7.5%; autoimmune hepatitis-2: 2.4%). Conclusions: In this large clinical series of Brazilian children and adolescents, autoimmune hepatitis-1 was more frequent, and patients with autoimmune hepatitis-2 exhibited higher disease remission rates with earlier response to treatment. Patients with autoimmune hepatitis-1 had a higher risk of death.

RESUMO Em sua tese de doutorado sobre o filme Fausto (1926), do alemão F. W. Murnau, o cineasta francês Éric Rohmer identifica no cinema, ou pelo menos no tipo de cinema mais convencional e narrativo que lhe interessa, três aspectos do espaço que ele denomina: pictórico, arquitetônico e fílmico. Como veremos, se essa divisão pode, por um lado, servir a uma função didática ligada ao aprendizado sobre a composição visual das imagens fílmicas, ela se revela, por outro lado, reducionista e artificial ao ignorar, ou ao menos desprezar, a componente temporal do cinema em favor de sua faceta espacial.

ABSTRACT In his doctoral thesis on F. W. Murnau’s film Faust (1926), French filmmaker Éric Rohmer identifies in cinema, or at least in the most conventional and narrative type of cinema that interests him, three aspects of cinematic space he calls: pictorial, architectural and filmic. As we shall see, if this division can, on the one hand, serve a didactic function linked to learning about the visual composition of filmic images, it is, on the other hand, a reductionist and artificial one by ignoring, or at least disregarding, the temporal component of the cinema in favor of its spatial facet.

RESUMO Terapias regenerativas vem sendo amplamente desenvolvidas na odontologia e o conhecimento destas novas terapias por parte dos dentistas é importante para que elas sejam incorporadas na rotina clínica odontológica. Assim, este estudo revisou a literatura acerca das terapias regenerativas e suas aplicações clínicas. A engenharia tecidual tem contribuído na mudança do paradigma restaurador das ciências da saúde. Seus pilares embasam as técnicas de regeneração de tecidos e órgãos. Apesar da grande maioria dos estudos neste campo ser in vitro, uma gama de metodologias pré-clínicas foi consolidada e estudos utilizando estes princípios já estão sendo empregados em humanos. A utilização de plasma rico em plaquetas e plasma rico em fibrina como scaffolds naturais em cirurgias para reestabelecimento de tecido ósseo e periodontal são frequentemente relatadas na literatura e ensaios clínicos utilizando esta abordagem demonstram resultados promissores. Células-tronco da polpa dental autólogas já foram aplicadas com sucesso na regeneração de tecido ósseo utilizando scaffold naturais de colágeno em humanos. Além disto, a revascularização do canal radicular já aparece na literatura como uma alternativa promissora frente a opção de apecificação do canal radicular. Esta terapia utiliza como princípio o coágulo sanguíneo como scaffold e a migração das células-tronco da papila apical para regenerar o órgão pulpar. Considerações finais: Apesar de incipientes, as terapias regenerativas já podem ser utilizadas na prática clínica odontológica. O conhecimento dos princípios que regem estas terapias deve ser compreendido pelo dentista para que sejam utilizadas na prática clínica.

ABSTRACT Regenerative therapies have been widely developed in dentistry and it is important to incorporate dentists’ knowledge of these new therapies into the dental clinic routine. This study reviewed the literature on regenerative therapies and clinical applications. Tissue engineering has contributed to changes in the paradigm of restorative health sciences. Its pillars underpin the techniques of tissue and organ regeneration. Despite the majority of studies in this field being in vitro, a range of preclinical studies and methodologies has been formed using these principles and they are already being used on humans. The use of platelet-rich plasma and platelet-rich fibrin in surgery as natural scaffolds for the reestablishment of bone and periodontal tissue are often reported in the literature and clinical trials using this approach have shown promising results. Stem cells from autologous dental pulp have been successfully applied in bone tissue regeneration using natural collagen scaffold in humans. In addition, revascularization of the root canal already appears in the literature as a promising alternative to apexification. The principle behind this therapy is the use of the blood clot as a scaffold and the migration of stem cells of the apical papilla to regenerate the dental pulp organ. Final considerations: Although still in the early stages, regenerative therapies can now be used in dental practice. Knowledge of the principles governing these therapies should be understood by the dentist for use in clinical practice.

RESUMO Zeólitas naturais são materiais adsorventes eficientes e com baixo custo para remoção de metais pesados em relação aos métodos convencionais. Este trabalho teve como objetivo avaliar o efeito do pH na capacidade máxima de remoção de cobre (Cu+2) por zeólita natural disponível na região do planalto catarinense (zeólita basalto - ZB) comparando sua eficiência com uma zeólita comercial importada de cuba (ZC). A capacidade de troca de cátions das zeólitas foi determinada pelo método de saturação por amônio. A densidade de partículas foi feita através do método do balão volumétrico. O efeito do pH na remoção foi avaliado a pH 3,0; 4,0 e 5,0 (±0,2) e concentrações iniciais de 10 mg L−1 e 180 mg L−1. A capacidade máxima de remoção de Cu+2 foi avaliada em pH 3,0; 4,0 e 5,0 e concentrações iniciais de 10, 30, 60, 90, 180 e 270 mg L−1. A quantificação do teor de Cu+2 foi realizada por espectrofotometria de absorção atômica com sistema de atomização por chama do tipo ar-acetileno. Para a construção das isotermas foi utilizado regressão polinomial e no teste de médias da porcentagem removida de Cu+2 em diferentes valores de pH foi utilizado Scott-Knott a 5% de significância. A ZC apresentou capacidade de troca de cátions 40% superior a ZB, porém isso não se refletiu na capacidade de remoção. Houve efeito do pH somente para ZC na menor concentração adicionada. A capacidade máxima de remoção foi de 2662 mg kg−1 para ZB e 2759 mg kg−1 para ZC em pH 5,0. A capacidade máxima de remoção de Cu+2 para ZB é semelhante ao da ZC. A ZB pode ser utilizada na remoção de metais em efluentes industriais e laboratoriais com baixo custo.

ABSTRACT Natural zeolites are effective adsorbent materials and low cost for removal of heavy metals compared to conventional methods. This study aimed to evaluate the effect of pH and the maximum capacity removal of copper (Cu+2) by natural zeolite available in the region of Southern Brazil (zeolite basalt - ZB) comparing its perfomance with a commercial zeolite imported from Cuba (ZC). The cation exchange capacity of the zeolites was determined by Ammonium saturation method. The particle density was taken by volumetric flask method. The effect of pH on removal was measured at pH 3.0, 4.0 and 5.0 (± 0.2) and initial concentrations of 10 and 180 mg L−1. The maximum capacity removal of Cu+2 was assessed at pH 3.0, 4,0 and 5.0 and the initial concentrations of 10, 30, 60, 90, 180 and 270 mg L−1. Quantification of Cu+2 was carried out by atomic absorption spectrometry with atomization system type air-acetylene. For the construction of the isotherms was used polynomial regression and the averaged test percentage of Cu+2 removed at different pH values was used the Scott-Knott 5% significance level. The ZC presented capacity cation exchange 40% higher than ZB, but this was not reflected in the removal capacity. There was effect of pH only for ZC in less concentration added. The maximum removal capacity was 2662 kg−1 mg for ZB and 2759 mg kg for ZC in the pH 5.0. The maximum capacity removal Cu+2 ZB is similar to ZC. The ZB can be used to remove metals in laboratory and industrial effluents with low cost.

Introdução: A melorreostose é uma doença rara, de etiologia ainda desconhecida e pouco descrita na literatura médica. A hiperostose linear ao longo do córtex ósseo causada pela doença é responsável pelo aspecto radiológico típico de cera derretida que deu nome à patologia. Objetivo e método: Relato de caso de uma paciente em acompanhamento ambulatorial por melorreostose, uma doença rara e de apresentação peculiar aos exames de imagem e revisão da literatura relacionada. Resultados: Paciente feminina, 42 anos, em acompanhamento ambulatorial por melorreostose umeral e de quirodáctilos à esquerda com diagnóstico há 7 anos e em tratamento clínico desde então. Possui apresentação típica da doença, com aumento de volume, associado à limitação de movimento e imagens radiológicas com hiperostose nos segmentos ósseos afetados. Conclusão: Apesar de benigna, a doença pode causar grande morbidade, principalmente pela dor crônica, limitação funcional e deformidades ósseas.

Introduction: Melorheostosis is a rare disease, whose etiology is still unknown and rarely reported on medical literature. The linear hyperostosis along the cortical bone caused by the disease is responsible for the typical radiologic appearance of melted wax that named the pathology. Objective and methods: a case report of a patient receiving outpatient treatment for melorheostosis, a rare disease with peculiar radiologic presentation, and review of the associated literature. Results: a female patient, 42 years old, recieving clinical outpatient treatment for melorheostosis in left upper arm and fingers, diagnosed 7 years ago. She shows a typical apresentation of the disease, with increased volume associated with limited movement and radiological images showing hyperostosis of the affected bone segments. Conclusion: although benign, the disease can cause large morbidity especially with chronic pain, functional limitations and bone deformities.
