Abstract:
Psidium guajava L. has extensive use in folk medicine. The aim of this study was to quantify the levels of phenolic, flavonoids, antioxidant activity, leathality assay and antibacterial and antitumoral activities of the extract of P. guajava. In the dry guava extract there were high levels of phenolics (766.08 ± 14.52 mg/g), flavonoids (118.90 ± 5.47 mg/g) and antioxidant activity (87.65%). The LD50 was 185.15 μg/ml. The MIC value was 250 μg/ml for Streptococcus mutans, Streptococcus mitis and Streptococcus oralis. IC50 of the extract tested in the HeLa, RKO and Wi cell lines was 15.6 ± 0.8 μg/ml, 21.2 ± 1.1 μg/ml and 68.9 ± 1.5 μg/ml, respectively. The results of all analyses allow us to conclude that the dry extract of guava leaves has promising activity to be applied topically in the oral cavity or in the development of antitumor formulation or even be used as a functional food.

Abstract: Experimentos foram realizados em uma fazenda comercial de cria o decamar es marinhos, objetivando avaliar a taxa de crescimento e sobrevivência das pós-larvas do Litopenaeus vannamei, quando cultivadas em tanques-ber ário e submetidas a diferentes dietas. As pós-larvas utilizadas encontravam-se com 19 dias (PL19) e foram estocadas a 16 PL/L, em tanques-ber ário de 60 m3. As pós-larvas foram submetidas ao Método de Alimenta o Convencional (MAC) e o Método de Alimenta o com Artêmia (MAA). Verificou-se que ao se correlacionar o peso em fun o do comprimento e do tempo de cultivo,o MAA apresentou uma rela o estatisticamente superior (p<0,05) ao MAC. A sobrevivência das pós-larvas alimentadas com MAA foi de 86,25%, enquanto que o MAC propiciou sobrevivência de 62,12%. A dieta com náuplios de artêmia é mais eficiente nas taxas de crescimento e sobrevivência das pós-larvas do Litopenaeus vannamei. Experiments were carried out in a commercial marine shrimp farm toevaluate growth and survival rate of the Litopenaeus vannamei post-larvae during nursery phase using different diets. The nursery tanks (60 m3) will be provided with post-larvae of 19 days (PL19) with a density of 16 PL/liter. The post-larvae were submitted to a Commercial Feeding Method (MAC) and an Artemia Feeding Method (MAA). Considering the correlations between weight and length, and between weight and culture duration, a better efficiency (p<0.05) of the MAA was verified. The survival rate of the post-larvae fed with MAA was 86.25%, while MAC yielded survivorship of 62.12%. Thus, artemia nauplii were proved to be more efficient, providing higher growth and survival rates of Litopenaeus vannamei post-larvae.
Influência de duas dietas na qualidade da água dos tanquesber ário, utilizados no cultivo do camar o marinho Litopenaeus vannamei (Boone, 1931)

Acta Scientiarum : Animal Sciences , 2006,
Abstract: Cultivos experimentais com pós-larvas do Litopenaeus vannamei, na fase de ber ário, foram realizados em uma fazenda de camar o, objetivando avaliar a influência da utiliza o de duas dietas na qualidade físico-química das águas residuais. As dietas foram formuladas à base de ra o comercial e náuplios de artêmia, denominadas MAC e MAA, respectivamente. Foram utilizadas pós-larvas no estágio (PL19), estocadas a 16PL/L em dois tanques-ber ário de 60 m3. Ao final de 10 dias de cultivo, as concentra es dos compostosnitrogenados (am nia, nitrito e nitrato) e fosfatados (fósforo total e ortofosfatos) dos tanquesber ário foram menores na dieta MAA do que na MAC (p<0,05). Conseqüentemente, a dieta MAA induziu menores taxas de incremento diário desses compostos, contribuindo com uma redu o significativa dos nutrientes responsáveis pela eutrofiza o da água. Experiments were carried out in a commercial marine shrimp farm in order to evaluate the use of two diets in Litopenaeus vannamei post-larvae, during nursery phase, on physiochemical wastewater quality. Two feeding methods were adopted: Commercial Feeding Method (MAC) and Artemia Feeding Method (MAA). The nursery tanks (60 m3) were provided with 19 days post-larvae (PL19) with a stocking density of 16PL/liter. After 10 days of culture, the concentrations of nitrogen (ammonia, nitrite and nitrate) and phosphorus compounds (total phosphorus and orthophosphate) in the nursery tank were smaller for MAC, rather than MAA treatment (p<0.05). Consequently, MAA treatment induced low levels of daily compounds increment,thus contributing to a significant reduction of the nutrients that caused water eutrophication.

Abstract: Recognizing the importance of an adequate characterization of radar absorbing materials, and consequently their development, the present study aims to contribute for the establishment and validation of experimental determination and numerical simulation of electromagnetic materials complex permittivity and permeability, using a Teflon sample. The present paper branches out into two related topics. The first one is concerned about the implementation of a computational modeling to predict the behavior of electromagnetic materials in confined environment by using electromagnetic three-dimensional simulation. The second topic re-examines the Nicolson-Ross-Weir mathematical model to retrieve the constitutive parameters (complex permittivity and permeability) of a homogeneous sample (Teflon ), from scattering coefficient measurements. The experimental and simulated results show a good convergence that guarantees the application of the used methodologies for the characterization of different radar absorbing materials samples.

Abstract: we have previously reported that prothrombin fragment 1+2 levels were not associated to the presence or severity of coronary artery disease (cad) and do not provide further information on subjects with cad diagnosed by angiography. thus, in the present study another marker of hypercoagulability was evaluated in the same subjects. this study aimed at determining d-dimer plasma levels in a group of subjects undergoing coronary angiography to establish a likely relation between this parameter and the severity of cad. d-dimer plasma levels were determined in 17 subjects with no coronary atheromatosis (controls), 12 subjects with mild/moderate atheromatosis and 28 subjects with severe atheromatosis. no significant differences were observed among the three groups. data analysis enables an inference on a tendency towards an increase in fibrinolytic activity in patients with atheromatosis, reflected by the increase in d-dimer concentrations in the severe atheromatosis group in subjects with cad diagnosed by coronary angiography.
