Abstract We investigated the Biogran on bone repair and metabolism at several time-intervals upon grafting into rat tibia artificial defects. The biomaterial was thoroughly characterized in vitro, and its dissolution behavior upon immersion was assessed in simulated body fluid (SBF) solution for 1, 3, 7, 14, and 30 days. Biogran was also assessed by in vitro hydroxyapatite formation in SBF solution, which is a marker for bioactive behavior. In vivo, distal and proximal bone defects were performed in the Wistar rat's right tibia and filled according to the experimental groups: I) negative control, no filling; II) positive control, 10 mg of autogenous bone; and III) 10 mg of Biogran. Animals were euthanized at 1, 2, 3, 4, 7, and 10 weeks. Bone neoformation was analyzed using histomorphometry (proximal defect), and local levels of bone morphogenetic protein 2 (BMP-2) were measured using the ELISA assay (distal defect). In vitro, the Biogran sample showed a fast dissolution rate within the first 7 days, parallel to the formation of the hydroxyapatite layer. In vivo, the sample was progressively resorbed at a higher rate within the first month until it became almost absent at week 10th. The sample presented similar or higher bone neoformation concerning the autogenous bone. BMP-2 levels were sustained in the Biogran group (around 200 pg/mg) and detected until the last experimental time with a significant difference compared with the controls. Results suggest Biogran is a candidate for hard tissue engineering even in highly active bone remodeling sites.

ABSTRACT: Pythiosis is the disease caused by aquatic oomycetes of the genus Pythium. In dogs the typical course of the disease involves the gastrointestinal tract, characterized by transmural thickening of the stomach or intestines. However, infection by Pythium spp. has only rarely been recognized as a cause of esophagitis in dogs. Thus, the present reports a case of esophageal and gastric pythiosis in an eight-month-old female pit bull dog. The dog was attended at the hospital after two months presenting regurgitation and dyspnea. It was reported that the dog lived in an urban area and had no previous sanitary issues. At clinical examination it was noted that the dog presented crackling sounds at pulmonary auscultation. A support therapy accompanied by antibiotics has been employed; however, 22 days after hospitalization the clinical condition worsened, and the dog died. At necropsy, the wall of the distal segment of the esophagus and the cardia and part of the fundus of the stomach were expanded by a focal extensive irregular intramural annular mass. Additionally, there was a transmural esophageal fistula. At histology, the walls of the esophagus and stomach were extensively expanded by multifocal extensive areas of necrosis, associated with a pyogranulomatous infiltrate and abundant granulation tissue containing multiple negative images of hyphae that were highlighted by silver impregnation (Grocott). Furthermore, immunohistochemistry and PCR for P. insidiosum were both positive in samples of paraffin-embedded esophageal tissue.

RESUMO: A Pitiose é uma doença causada por oomicetos aquáticos do gênero Pythium. Em cães o curso típico da doença envolve o trato gastrointestinal, caracterizado por espessamento transmural do estômago ou intestinos. No entanto, a infecção por Pythium spp. raramente foi reconhecida como causa de esofagite em caninos. Assim, o presente trabalho tem como objetivo relatar um caso de pitiose esofágica e gástrica em um canino Pit Bull fêmea de oito meses de idade. O cão foi recebido no hospital com histórico de regurgitação e dispneia durante dois meses. Foi relatado que o animal era de um domicílio de área urbana e não possuía histórico pregresso de enfermidades. No exame clínico contatou-se ainda crepitações à ausculta pulmonar. Foi instituído tratamento de suporte e antibioticoterapia, porém após 22 dias de internação, o cão evoluiu para o óbito. Na necropsia, as paredes do segmento distal do esôfago e o cárdia e parte do fundo do estômago estavam expandidos por uma massa anular intramural focalmente extensiva e irregular. Além disso, havia uma fístula esofágica transmural. À histologia, as paredes do esôfago e do estômago apresentavam-se difusamente expandidas por áreas multifocais extensas de necrose, associadas a infiltrado piogranulomatoso, abundante proliferação de fibroblastos imaturos, neovascularização e contendo múltiplas imagens negativas de hifas realçadas pela impregnação por prata (Grocott). Além disso, tanto a imuno-histoquímica como PCR para P. insidiosum foram positivas em amostras de esôfago embebidas em parafina.

SUMMARY: This study aimed to evaluate the effects of six weeks of HIIT on tissue and oxidative damage markers in rats supplemented with Coutoubea spicata fraction. Thirty-two male Wistar rats were divided into 4 groups: Baseline (GB); supplemented with 100 mg/kg of Coutoubea spicata fraction (GSCS); exercised for 6 weeks with the HIIT protocol (GH); supplemented with 100 mg/kg of Coutoubea spicata fraction + HIIT for 6 weeks (GHCS). Exercised animals performed the HIIT protocol (2 x 2). Tissue damage CK, LDH, ALT and AST markers in plasma were analyzed, as well as oxidative stress MDA and SH biomarkers in plasma and in cardiac, hepatic and muscle tissues. The results showed that CK, LDH, AST and ALT enzymes showed increase in GH when compared to GB (p<0.0001). However, CK, AST and ALT markers reduced their concentrations in GHCS when compared to GH (p<0.0001), indicating that Coutoubea spicata supplementation attenuated the damage in muscle and liver tissues induced by HIIT. Plasma, liver and muscle MDA showed increase in GH after HIIT sessions; however, when compared to GHCS, it showed reduced levels (p<0.0001). SH was elevated in the GH group when compared to GB in plasma and liver tissues (p<0.0001); in contrast, reduction in GHCS when compared to GH was observed in plasma, liver and cardiac tissues, demonstrating the redox effect of HIIT on some tissues. Thus, our findings showed that Coutoubea spicata has antioxidant activity, reducing oxidative damage markers and consequently tissue damage in healthy Wistar rats after HIIT protocol, but it also demonstrated redox balance after analyzing oxidative stress markers.

RESUMEN: Este estudio tuvo como objetivo evaluar los efectos de HIIT en los marcadores de daño tisular y oxidativo en ratas suplementadas con Coutoubea spicata durante seis semanas. Treinta y dos ratas Wistar macho se dividieron en 4 grupos: línea de base (GB); suplementados con 100 mg/kg de fracción de Coutoubea spicata (GSCS); ejercitados durante 6 semanas con el protocolo HIIT (GH); suplementado con 100 mg/kg de fracción de Coutoubea spicata + HIIT durante 6 semanas (GHCS). Los animales ejercitados realizaron el protocolo HIIT (2x2). Se analizaron los marcadores de daño tisular CK, LDH, ALT y AST en plasma, así como los biomarcadores de estrés oxidativo MDA y SH en plasma y en tejidos cardiaco, hepático y muscular. Los resultados indicaron que las enzimas CK, LDH, AST y ALT mostraron aumento en GH en comparación con GB (p<0,0001). Sin embargo, los marcadores CK, AST y ALT redujeron sus concentraciones en GHCS en comparación con GH (p<0,0001), lo que indica que la suplementación con Coutoubea spicata atenuó el daño en los tejidos musculares y hepáticos inducido por HIIT. La MDA de plasma, hígado y músculo mostró un aumento en la GH después de las sesiones de HIIT; sin embargo, en comparación con GHCS, mostró niveles reducidos (p<0,0001). Se observó SH elevado en el grupo de GH en comparación con GB en plasma y tejidos hepáticos (p<0,0001); en contraste, se observó una reducción en GHCS en comparación con GH en plasma, hígado y tejidos cardíacos, lo que demuestra el efecto redox de HIIT en algunos tejidos. Por lo tanto, nuestros hallazgos mostraron que Coutoubea spicata tiene actividad antioxidante, con reducción de los marcadores de daño oxidativo y, en consecuencia, el daño tisular en ratas Wistar sanas después del protocolo HIIT, pero además demostró el equilibrio redox después de analizar los marcadores de estrés oxidativo.

Resumo O objetivo deste estudo foi descrever a correlação entre dados de composição corporal obtidos através de DEXA, e pela estratégia de dobras cutâneas, com algumas de suas respectivas fórmulas, em velocistas. A amostra foi composta por 15 velocistas do sexo masculino (23,81 anos ± 3,11; 70,06 Kg ± 4,38; e 179,13 cm ± 5,16) todos corredores de alto desempenho das provas de velocidade e barreiras (100m, 200m, 400m, 110m com barreiras e 400m com barreiras). Os atletas foram submetidos ao procedimento de avaliação do DEXA e a coleta de dobras cutâneas (tricipital, bicipital, subescapular, supra ilíaca, abdominal, coxa medial e panturrilha) e os resultados calculados através de quatros distintas equações Slaughter, Faulkner, Lázari e Boileau. As respectivas correlações (0,60; 0,81; 0,23 e 0,48) de DEXA e as equações previstas pela estratégia de dobras cutâneas foram calculadas através da correlação de Pearson. Dentre as equações utilizadas, a de Faulkner foi a que apresentou maior valor de correlação quando comparada ao protocolo do DEXA, apesar de todas terem por objetivo estimar valores para o %G.

Abstract The aim of this study was to describe the correlation between body composition data obtained through DXA and through skinfolds strategy, with some of their respective formulas, in sprinters. The sample consisted of 15 male sprinters (23.81 years ± 3.11; 70.06 Kg ± 4.38; and 179.13 CM ± 5.16) all high performance runners of speed and barriers events (100m, 200m, 400m, 110m with barriers and 400m with barriers). The athletes were submitted to DXA evaluation procedure and to skinfolds collection (triceps, biceps, subscapular, supra iliac, abdominal, medial thigh and calf) and the results were calculated through four distinct equations: Slaughter, Faulkner, Lázari and Boileau. The respective DXA correlations (0.60; 0.81; 0.23 and 0.48) and the equations predicted by skinfold strategy were calculated using Pearson correlation. Among the equations used, Faulkner's was the one presenting highest correlation value when compared to DXA protocol, although all of them aimed to estimate values for BF%.

Abstract Background: the biological activity of vitamin D depends on the activity of its receptor or VDR. On the other hand, the activity of this receptor is influenced by its state of methylation. The objective of this study was to verify if the BsmI polymorphism of the VDR gene influences its methylation profile in adolescents. Secondly, it was to verify if the status of some metabolic factors (oxidative stress, inflammation, lipid profile, and glycemia) in the serum, and gender-adjusted vitamin D levels are independent factors with an influence on the VDR methylation profile. Methods and results: the study included 198 adolescents of both sexes, aged 15-19 years, who underwent testing for VDR gene methylation polymorphisms, serum vitamin D levels, and metabolic, oxidative stress, and systemic inflammation markers. It was observed that the BB genotype was less methylated than the other groups (26.1 % versus 30.3 %, and 29.3 % for Bb and bb, respectively), although without statistical differences between them. The odds ratio indicated a protection of 13 % (partially methylated) for vitamin D status, while alpha glycols increased the risk ratio (of being partially methylated) by 3 %. MDA was protective at a 28 % chance of risk that adolescents with higher levels of lipid peroxidation would be hypomethylated. Conclusion: we conclude that the methylation profile of the VDR gene is not influenced by the different BsmI polymorphism genotypes, and that serum vitamin D and serum markers of oxidative stress and inflammation can modulate this profile.

Resumen Antecedentes: la actividad biológica de la vitamina D depende de la actividad de su receptor, el VDR. Por otro lado, la actividad de este receptor está influenciada por su estado de metilación. El objetivo de este estudio es verificar si el polimorfismo BsmI del gen VDR influye en el perfil de metilación del mismo en los adolescentes. En segundo lugar, verificar si los factores metabólicos (estrés oxidativo, inflamación, perfil lipídico y glucemia) del suero y la vitamina D ajustada por sexo actúan independientemente de los polimorfismos sobre el perfil de metilación del VDR. Métodos y resultados: el estudio incluyó a 198 adolescentes de ambos sexos, de 15 a 19 años de edad, que se sometieron a análisis de polimorfismos de metilación del gen VDR, niveles de vitamina D, marcadores metabólicos, estrés oxidativo e inflamación sistémica. Se observó que el genotipo BB estaba menos metilado que los otros grupos (26,1 % contra 30,3 % y 29,3 % para Bb y bb respectivamente), aunque sin diferencias estadísticas entre ellos. El odds ratio indicó una protección del 13 % (parcialmente metilado) para el estado de la vitamina D, mientras que los alfa glicoles aumentaron el índice de riesgo (de estar parcialmente metilado) en un 3 %. La MDA fue protectora con un 28 % de probabilidad de riesgo de que los adolescentes con niveles más altos de peroxidación lipídica fueran hipometilados. Conclusión: concluimos que el perfil de metilación del gen VDR no está influenciado por los diferentes genotipos del polimorfismo BsmI y que la vitamina D y los marcadores de estrés oxidativo e inflamación en el suero pueden modular este perfil.

ABSTRACT. The layer poultry is an important activity for food production with high biological value. Measuring egg quality has great relevance to ensure safety and quality products for consumers. Thus, the objective was to evaluate the egg physical quality of four laying hen’s strains. Were used 864 eggs from four laying hens’ lines (Hisex Brown®, Hy-Line Brown®, Isa Label®, and Lohmann Brown®). The experimental design was completely randomized composed of four treatments (strains) with nine replications with four eggs each. Egg weight, egg diameter, egg length, specific gravity, yolk, albumen and shell weight and percentage, Haugh units, and shell thickness were evaluated. There was a significant difference for all parameters evaluated. The Hisex Brown® strain showed the best results for egg diameter, egg length, specific weight, albumen height, Haugh units, yolk weight, albumen%, shell weight, shell%, and shell thickness, while the Hy-Line Brown® produced bigger and heavier eggs, and Isa Label® presented the highest yolk%. The Hisex Brown® strain showed the better physical quality of eggs when compared to the other studied lines, the strain being indicated when the objective is to produce eggs with better internal and external quality.

ABSTRACT BACKGROUND: This study identified and summarized all Cochrane systematic reviews (SRs) on the effects of ten integrative practices that were recently added to the Brazilian public healthcare system (SUS). DESIGN AND SETTING: Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina (EPM), Universidade Federal de São Paulo (Unifesp). METHODS: Review of Cochrane SRs on the following interventions were identified, summarized and critically assessed: apitherapy, aromatherapy, bioenergetics, family constellation, flower therapy, chromotherapy, geotherapy, hypnotherapy, hand imposition or ozone therapy. RESULTS: We included a total of 16 SRs: 4 on apitherapy, 4 on aromatherapy, 6 on hypnotherapy and 2 on ozone therapy. No Cochrane SR was found regarding bioenergetics, family constellation, chromotherapy, clay therapy, flower therapy or hand imposition. The only high-quality evidence was in relation to the potential benefit of apitherapy, specifically regarding some benefits from honey dressings for partial healing of burn wounds, for reduction of coughing among children with acute coughs and for preventing allergic reactions to insect stings. CONCLUSION: Except for some specific uses of apitherapy (honey for burn wounds and for acute coughs and bee venom for allergic reactions to insect stings), the use of ten integrative practices that have recently been incorporated into SUS does not seem to be supported by evidence from Cochrane SRs.

Resumo Este trabalho visa compreender as motivações e os fatores que condicionam a participação ativa no controle social, contribuindo para a literatura de administração pública num campo que ainda há espaço para ser explorado. Além disso, fornece subsídios para que os atores públicos possam formular ações que visam fortalecer as iniciativas de envolvimento dos cidadãos com a gestão pública, em especial, por meio das organizações da sociedade civil. Para isso, tem como principais abordagens teóricas as racionalidades instrumental e substantiva nas organizações públicas e as motivações para a participação cidadã. A técnica empregada para o exame das informações foi a análise de conteúdo, com base no qual foi elaborado um roteiro para a realização de entrevistas em profundidade com membros de uma ONG que atua ativamente no combate à corrupção municipal. Os principais resultados apontam para a complementaridade das racionalidades no processo motivacional da participação cidadã no controle social. O estímulo à participação emerge do valor concedido ao exercício do controle social, advindo da racionalidade substantiva, ao passo que a racionalidade instrumental apresenta-se como um meio de garantir a eficiência e a eficácia da atuação comunitária dos cidadãos.

Abstract This work aims to understand the motivation and factors that influence active participation in social accountability, contributing to literature on public administration in a field which is not fully explored. This study provides elements to help public actors to strengthen initiatives of citizens’ engagement in public management, especially by working with civil society organizations. The main theoretical approaches are the instrumental and the substantive rationality in public organizations, as well as the motivation for citizen participation. Information was collected through in-depth interviews. Content analysis was used to examine the information, allowing to achieve the objectives of the study. The main results indicate the complementarity of both instrumental and substantive rationality in motivating citizen participation in initiatives of social accountability. The motivation to participate comes from the value given to social accountability, which is related to substantive rationality, while the instrumental rationality appears as a means of ensuring the efficiency and the effectiveness of citizens’ community actions.

In Brazil, despite the high share of renewable energy sources in the energy mix compared to the world average, the use of gas generated by landfills for power generation is still incipient. There are landfills recently implanted with the purpose to produce electricity from biogas, but the oldest installations do not have this structure. Since the oil industry is energy intensive, the article proposes the evaluation of waste gas use in the steam generation system of a typical refinery in Brazil to generate electricity and feed the refinery process units and considering the economic impact. In this sense, it presents an analysis based on real data to contextualize and quantify the waste biogas potential in a specific landfill in Brazil. The study considers a landfill at the end of life (17 years), and the reuse of the residual gas generated until the full depletion of gases considering a case study with real data obtained from an existing landfill

En Brasil, a pesar del alto porcentaje de las energías renovables en el mix energético en comparación con el promedio mundial, el uso de gas generado por los vertederos para la generación de energía es aún incipiente. Hay vertederos desplegadas recientemente con el objetivo de producir electricidad a partir de biogás, pero las plantas más viejas, no tienen esta estructura. Dado que la industria petrolera es de alto consumo energético, este artículo propone la evaluación de la utilización de los gases residuales en el sistema de generación de vapor de una refinería típica en Brasil para generar electricidad y alimentar las unidades de proceso de la refinería. En este sentido, se presenta un análisis basado en datos reales para contextualizar y cuantificar el potencial de biogás de residuos en Brasil. Este estudio considera un relleno al final de la vida (17 años), y la reutilización del gas residual generado hasta el agotamiento completo de gases, teniendo en cuenta un estudio de casos con datos reales de un vertedero existente

INTRODUCTION: In 2010, to reduce the occurrence of serious pneumococcal disease, the Ministry of Health in Brazil incorporated the 10-valent pneumococcal vaccine in the immunization schedule of children younger than two years of age. The objective of this study was to evaluate the impact of vaccination on the incidence of infectious respiratory diseases in infants before and after the introduction of the 10-valent pneumococcal vaccine. METHODS: This cross-sectional study involved primary care and hospital networks from a city in Minas Gerais State, Brazil, between 2009 and 2012. RESULTS: A 40% reduction in the prevalence of community-acquired pneumonia (CAP) was observed after introducing the pneumococcal conjugate vaccine. Male children were 28% more likely to develop the disease. The prevalence ratio ([PR] = 1.96, 95% CI: 1.52 to 2.53, p < 0.05) suggested that not being vaccinated was associated with the occurrence of pneumonia. The prevalence of CAP was 70% lower (PR 0.30, 95% CI: 0.24 to 0.37, p<0.05) in children vaccinated as recommended compared to children with delayed vaccination, suggesting that the updated vaccine schedule improves protection. CONCLUSIONS: Immunization with the 10-valent pneumococcal vaccine appeared to reduce the number of pneumonia cases in children during the study period. Prospective studies are needed to confirm the efficacy of the vaccine against the occurrence of pneumococcal pneumonia.

A prevalência de anticorpos para o vírus da Influenza Equina (VIE) no município de Poconé, MT. foi determinada em 529 equídeos pela técnica de Inibição da hemaglutinação utilizando como antígeno a variante H3N8 (SP/1/85). A distribuição da positividade e possíveis associações entre os animais e as propriedades foram avaliadas pelo teste do Qui-quadrado e pelos modelos espacial autoregressivo misto e de regressão linear múltipla. A prevalência de anticorpos para o VIE no município de Poconé foi estimada em 45,2% (IC 95% 30,2 - 61,1%) com títulos variando entre 20 e 1280UIH. Das fazendas analisadas 23 (92,0%) apresentaram animais soropositivos. Animais de fazendas não alagadas (66,5%) e negativos para Anemia Infecciosa Equina (AIE) (61,7%) foram associados a soropositividade. Não houve correlação espacial entre as fazendas estudadas, entretanto aquelas localizadas nas áreas não alagadas foram associadas à infecção. Observou-se correlação negativa entre a prevalência de anticorpos para o VIE e a presença de animais positivos para AIE nas propriedades. A elevada prevalência de anticorpos para o VIE detectada neste estudo sugere circulação viral ativa entre os animais, e as análises estatísticas indicam que o trânsito e aglomeração animal são fatores associados à transmissão do vírus na região.

The prevalence of antibodies against Equine Influenza Virus (EIV) was determined in 529 equines living on ranches in the municipality of Poconé, Pantanal area of Brazil, by means of the hemagglutination inhibition test, using subtype H3N8 as antigen. The distribution and possible association among positive animal and ranches were evaluated by the chi-square test, spatial autoregressive and multiple linear regression models. The prevalence of antibodies against EIV was estimated at 45.2% (95% CI 30.2 - 61.1%) with titers ranging from 20 to 1,280 HAU. Seropositive equines were found on 92.0% of the surveyed ranches. Equine from non-flooded ranches (66.5%) and negativity in equine infectious anemia virus (EIAV) (61.7%) were associated with antibodies against EIV. No spatial correlation was found among the ranches, but the ones located in non-flooded areas were associated with antibodies against EIV. A negative correlation was found between the prevalence of antibodies against EIV and the presence of EIAV positive animals on the ranches. The high prevalence of antibodies against EIV detected in this study suggests that the virus is circulating among the animals, and this statistical analysis indicates that the movement and aggregation of animals are factors associated to the transmission of the virus in the region.

Introdução: A rotura tendão distal do bicípite braquial é uma lesão rara, representando menos de 3% de todas as roturas bicípite braquial. Maioria das roturas ocorrem no braço dominante, em homens com idades compreendidas entre 30 a 49 anos, quando uma carga excentrica é exercida sobre o bicipite. Nos casos de rotura completa, o músculo retrai proximalmente dando origem ao chamado sinal de "Musculo de Popeye". Casos clínicos: Apresentamos dois doentes do sexo masculino com o diagnóstico de rotura do tendão distal do músculo bicípite braquial que foram submetidos a tratamento cirúrgico pela técnica de duas incisões, descrita por Boyd e Anderson. Discussão: Existem várias opções terapêuticas (conservadoras e cirúrgicas) para a rotura do tendão distal do bicípite. Doentes que foram tratados conservadoramente tendem a apresentar défi ces clínicos evidentes. Bons a excelentes resultados foram descritos para o tratamento cirúrgico precoce, com recuperação funcional completa e elevado grau de satisfação dos doentes. Conclusão: Nós concluimos que a técnica Boyd e Anderson é segura e eficaz na reparação da rotura do tendão distal do bicipete braquial. Os nossos resultados vão ao encontro de que uma reparação anatómica dá consistentemente bons resultados.

Introduction: Complete distal biceps tendon ruptures are uncommon injuries, representing approximately 3% of all biceps brachii injuries. Most ruptures occur in the dominant arm in men between the ages of 30 and 49 years, when an eccentric load is exerted on the biceps. If there is complete rupture, the muscle belly may retract proximally. This is known as the "Popeye muscle" sign. Case Report: We report the cases of two male patients with the diagnosis of distal biceps tendon rupture, who were submitted to surgical treatment by the Boyd and Anderson technique. Discussion: Many techniques , including non-operative and surgical option, have been described for the treatment of the ruptured distal bicep tendon. Patients who had conservative treatment showed a remaining deficit clinically evident in several activities. Good to excellent results have been reported for early surgical repair of the torn tendon with improved functional outcomes and improved patient satisfaction. Summary: We conclude that this minimally invasive technique is safe and effective. Our findings are in agreement with the view that anatomic repair of distal biceps tendon rupture provides consistently good results.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Devido a altas perdas de pedúnculos de caju, métodos de conservação são necessários para um maior aproveitamento dos mesmos. Com esse objetivo, pedúnculos de caju vermelho, maduros, obtidos de cajueiro anão precoce, foram irradiados com doses de 0, 0,5 e 1,0 kGy e armazenados por 9 dias, refrigerados 4 ºC para verificação da estabilidade da qualidade durante o período de armazenamento. Para isso foram realizadas análises químicas, verificando mudanças nos teores de açúcares redutores, Brix, vitamina C e pH. Alterações na firmeza e cor também foram observadas. Os teores de vitamina C diminuíram tanto em função do tempo de estocagem como em função das doses de radiação empregadas. A firmeza dos frutos foi influenciada tanto pelas diferentes doses de radiação quanto pelo armazenamento, aumentando durante o armazenamento e diminuindo quanto maiores as doses de irradiação. O método de conservação por irradiação mostrou-se eficiente para o prolongamento da vida de prateleira dos pedúnculos de caju e manutenção de sua qualidade pós-colheita.

The non-efficiency or absence of techniques for adequate handling, transport, and storage of cashew stalks associated with a high level of perishability, generates high economic loss in the commercialization of these fruits, hence the development of conservation methods becomes a necessity in order to enhance the profitability. Cashew apples from precocious dwarf cashew tree were irradiated with doses of 0, 0.5, and 1.0 kGy and stored during nine days under refrigeration at 4 ºC for evaluation of the quality stability during storage. Chemical analyses were performed to verify changes in reducing sugars, Brix, vitamin C, and pH. Alterations in the firmness and color were also observed. The levels of vitamin C decreased as a function of storage as well as a function of the radiation doses employed. The firmness of the fruits was influenced by both the radiation doses and storage time, increasing during storage and decreasing as the radiation doses increased. Irradiation was shown to be efficient in the prolongation of the shelf-life of cashew stalks.
