ABSTRACT: Seafood is one of the most important sources of nutrients. However, they have a short shelf-life and the traditional preservation methods may generate losses in their natural flavour and nutrients. Thisstudy evaluated and optimize the High Pressure Processing (HPP) regarding pressure level (200-400 MPa) and holding time (0-5 min) applied to lion’s paw scallop (Nodipecten nodosus) to reduce microbial contamination while maintaining desirable characteristics. Response surface methodology with a Box-Behnken design and Desirability function were employed to simultaneously optimize these quality attributes. HPP enhanced microbial quality at 200 MPa/5 min, despite promoting inadequate physical-chemical modifications in the adductor muscle of the scallop. In such processing condition, in spite of a slight increase in muscle humidity which could be of benefit, pH increase was also verified, as well as a decrease in water holding capacity (WHC). At more severe level (400 MPa/5 min), a decrease in the shear force related to instrumental texture and in Whiteness (W) and Luminosity (L*) related to color was observed. Simultaneous optimization provided a value of 365MPa / 2min where physicochemical characteristics would be the more similar to the scallop without facing a preservation process.

RESUMO: Os frutos do mar são uma das fontes mais importantes de nutrientes. No entanto, possuem vida de prateleira curta e os métodos tradicionais de conservação podem gerar perdas em seu sabor natural e nutrientes. O objetivo deste estudo foi avaliar e otimizar o Processamento por Alta Pressão (APH) em relação ao nível de pressão (200-400 MPa) e tempo de espera (0-5 min) aplicado à vieira pata de leão (Nodipecten nodosus) para reduzir a contaminação microbiana, mantendo características desejáveis. Metodologia de superfície de resposta com design Box-Behnken e função de Desejabilidade foram empregadas para otimizar simultaneamente esses atributos de qualidade. A APH melhorou a qualidade microbiana a 200 MPa/5 min, apesar de promover modificações físico-químicas inadequadas no músculo adutor da vieira. Nessa condição de processamento, apesar de um leve aumento da umidade do músculo que poderia ser benéfico, também foi verificado aumento do pH, bem como diminuição da capacidade de retenção de água (CRA). No nível mais severo (400 MPa/5 min), observou-se uma diminuição na força de cisalhamento relacionada à textura instrumental e na Brancura (W) e Luminosidade (L*) relacionada à cor. A otimização simultânea proporcionou um valor de 365MPa/2min em que as características físico-químicas seriam as mais semelhantes às da vieira sem enfrentar um processo de preservação.

ABSTRACT Purpose: This study aimed to evaluate the therapeutic effect of an ethanol extract of Ocimum basilicum L. (EEOb) aerial parts against Ehrlich’s experimental tumor (EET) in mice. Methods: Swiss mice were divided into two groups (control and treated; n = 6). On day 21, all mice were inoculated subcutaneously with 2 × 106 (0.05 mL) EET cells in the left paw for solid tumor development. This study lasted 28 days. Treatment began 24 hours after inoculation with EET. Measurements of dorsoplantar thickness were used to assess tumor growth. The paw pad was collected for histopathological analysis and stained using the argyrophilic nucleolar organizing regions (AgNOR) technique and immunohistochemistry for proliferating cell nuclear antigen, Bcl-2 and Bax. Results: The treatment of animals with EEOb at 100 mg/kg intraperitoneally was able to reduce the growth (Control = 3.7 ± 0.1 mm vs. EEOb = 5.7 ± 0.2 mm) and the number of AgNORs of solid Ehrlich tumor. The antitumor effect of EEOb was associated with the induction of apoptosis of tumoral cell, as suggested by the reduction of the content of Bcl-2 induced by extract. Conclusions: The study demonstrated that daily administration of EEOb is able to reduce the growth of EET by induce apoptosis of tumoral cells.

RESUMO Objetivos: O presente estudo teve por objetivo avaliar a segurança da injeção intravítrea de 0,1 ml de sunitinibe em duas concentrações (1 mg/ml e 10 mg/ml), 0,1 ml de dispersão contendo nanopartículas lipídicas sólidas sem droga e 0,1 ml de dispersão contendo nanocápsulas poliméricas livre de drogas analisando os possíveis efeitos tóxicos à retina de coelhos albinos detectados pela eletrofisiologia e histologia por microscopia óptica. Métodos: Um estudo controlado experimental foi realizado com 20 olhos de coelhos albinos. Foram realizadas injeções intravítrea de duas concentrações diferentes de sunitinibe, uma dispersão contendo nanopartículas lipídicas sólidas e uma dispersão contendo nanocápsulas. O olho contralateral não recebeu tratamento e foi utilizado como controle. Resultados: Não foram observadas alterações eletrorretinográficas nos grupos do sunitinibe (1 mg/ml e 10 mg/ml) e no grupo das nanopartículas lipídicas sólidas. No grupo das nanocápsulas, houve alterações significativas tanto na morfologia, quanto na amplitude e tempo das ondas do eletrorretinograma. Ao estudo histológico, somente o grupo das nanocápsulas apresentou alterações degenerativas (núcleos tumefeitos) com acentuado edema e formação de vacúolos citoplasmáticos, sugerindo toxidade retiniana. Conclusões: As injeções intravítreas de sunitinibe e nanopartículas lipídicas sólidas não foram tóxicas para a retina. No entanto, nanocápsulas mostraram ser tóxicas para a retina. Sendo assim, a possibilidade de poder combinar o potencial de uma droga que possui a capacidade de inibir duas importantes vias da angiogênese, às vantagens de liberação controlada das nanopartículas lipídicas sólidas, pode ser um importante recurso terapêutico para doenças vasoproliferativas oculares.

ABSTRACT Purpose: We aimed to evaluate the safety of single intravitreal injection of each of two concentrations of 0.1 ml of sunitinib (1 and 10 mg/ml), 0.1 ml of a drug-free dispersion containing solid lipid nanoparticles, and 0.1 ml of a drug-free dispersion containing polymeric nanocapsules for analyzing the possible toxic effects using electrophysiology and histology in albino rabbit retina. Methods: We conducted an experimental controlled study of 20 eyes of albino rabbits. Intravitreal injections of each specific agent were applied to one eye per rabbit in each 5-rabbit group, while the contralateral eyes received no treatment and were used as controls. Results: We noted no electroretinographic changes in the sunitinib (1 and 10 mg/ml) or in solid lipid nanoparticles groups. However, we observed significant abnormalities in ocular morphology and in the electroretinogram in the nanocapsules group. At the histological level, only the nanocapsules group demonstrated abnormal changes, including severe edema and cytoplasmic vacuole formation. Conclusions: While nanocapsules intravitreal injections indicated retinal toxic effects, sunitinib and solid lipid nanoparticles intravitreal injections were not toxic to the retina. Our results suggest that a sunitinib preparation with solid lipid nanoparticles for controlled release may offer a significant therapeutic approach for vasoproliferative ocular disease.

Abstract A sample of 39 rats were divided into the following groups: baseline (BL); aerobic training (ET4 and ET8); anaerobic training (ST4 and ST8); and concurrent training (CT4 and CT8). The aerobic training was performed by swimming with a load corresponding to 70% of the anaerobic threshold; the anaerobic training was performed by jumping in water with a load corresponding to 50% of body weight; and the concurrent training combined the two protocols. The analysis of BMDwas performed on the tibia of the animals and showed an increase in the density of the ST4, CT4, ET8, ST8, and CT8 groups when compared with both the BL and ET4. Thus, it is concluded that anaerobic exercise was shown to be effective in increasing the BMD of animals afterfour weeks of training; however, aerobic training was only able to raise BMD following eight weeks of training.

ABSTRACT: This paper addresses the subject of fiber optic chromatic dispersion effect on the performance of analog optical link with dual-drive electro-optic Mach-Zehnder modulator, aiming at aerospace applications. Thus, a direct detection link model that emphasizes both the modulator electronic drive and the dispersion characteristic of a linear optical fiber is discussed. Furthermore, a mathematical approach yielding a rather insightful analysis of the link performance for either optical double or single sideband modulation formats is fully discussed. It is worthwhile to point out that such modeling has the special feature of relying on a uniform nomenclature, which enables one to quickly retrieve a wide range of known results regarding optical fiber link performance that are already available on an ample literature. The model usefulness is illustrated by predicting the performance dependence of a direct detection fiber optic link with respect to the radiofrequency and link length. Results of numerical simulations for a link that comprises commercial optoelectronic components with potential for practical application on electronic warfare field were also provided.

O objetivo do presente trabalho foi verificar e comparar a transferência de imunidade passiva e o proteinograma em bezerros da raça Crioula Lageana (CL) e Holandesa Preta e Branca (HPB). Foram utilizados dois grupos sendo 13 bezerros da raça Crioula Lageana e 10 da raça HPB. Amostras de sangue foram colhidas para a mensuração da proteína sérica total, eletroforese das proteínas séricas, atividade da gama-glutamiltransferase e concentração de IgG pelo método de turvação pelo sulfato de zinco nos períodos entre 24 e 36 horas de vida, 15, 30, 60, 90, 120, 150 e 180 dias. A análise estatística foi realizada pelo teste de ANOVA e Tukey ao nível de 5% de significância, e correlações entre as variáveis. As variações das proteínas séricas obedeceram a um padrão de comportamento fisiológico ao longo dos seis primeiros meses de vida e a produção ativa de imunoglobulinas foi mais precoce nos bezerros da raça Holandesa e mais lenta nos da raça Crioula Lageana, sem provocar qualquer impacto sobre a saúde dos mesmos. A gamaglobulina no primeiro dia de vida (24-36h) correlacionou-se com a IgG (r=0,87 CL e r=0,89 HPB), PTS (r=0,91 CL e r=0,92 HPB), Glob (r=0,99 CL e r=0,98) e GGT (r=0,14 CL e r=0,83 HPB). Conclui-se que não houve falha na transferência de imunidade passiva nos bezerros da raça Crioula Lageana e falha na raça Holandesa Preta e Branca. Os valores de IgG estimados pelo método da turvação pelo sulfato de zinco e das proteínas séricas foram bons indicadores da transferência de imunidade passiva nos bezerros entre 24 e 36 horas de vida.

The objective of this study was to evaluate and compare the transfer of passive immunity and the proteinogram in Criollo Lageano (CL) and Black and White Holstein (BWH) calves. Two groups were utilized with 13 Criollo Lageano and 10 BWH calves. Blood samples were collected for the measurement of total serum protein, electrophoresis of serum proteins, activity of the gamma glutamyl transferase, and concentration of IgG by the method of the zinc sulfate turbidity in periods between 24 and 36 hours of life, 15, 30, 60, 90, 120, 150 and 180 days. Statistical analysis was performed by ANOVA and Tukey test at 5% significance level, and correlations between variables were calculated. Variations of serum proteins followed a pattern of physiological behavior over the first six months of life and production of immunoglobulins was active earlier in BWH calves and slower in the Criollo Lageano, without causing any impact on their health. Gamma globulin in the first days of life (24-36h) was correlated with IgG (r=0.87 for CL and r=0.89 for BWH), PTS (r=0.91 for CL and r=0.92 for BWH), Glob (r=0.99 for CL and r=0.98 for BWH) and GGT (r=0.14 for CL and r=0.83 for BWH). It was concluded that there was no failure in the transfer of passive immunity in Criollo Lageano calves but this failure occurred in the BWH calves. IgG values estimated by the zinc sulfate turbidity and serum proteins were considered good indicators of the transfer of passive immunity in calves between 24 and 36 hours of life.
