14. Bioactive fractions from cantabrian anchovy (Engraulis encrarischolus) viscera
Abstract The potential of cantabrian anchovy (Engraulis encrarischolus) viscera as a source of bioactive compounds is of interest for both, pharmaceutical and food industries. Cantabrian anchovy guts and heads were freeze-dried, extracted with methanol and subjected to fractionation by solvent partitioning using hexane, ethyl acetate, and butanol. Fractions

15. Biodistribution, pharmacokinetics and toxicity of a Vasconcellea cundinamarcensis proteinase fraction with pharmacological activity
Abstract Prior studies demonstrate that a proteinase fraction from Vasconcellea cundinamarcensis V.M. Badillo, Caricaceae, exhibits wound healing activity in gastric and cutaneous models and antitumoral/antimetastatic effects. Here, we present the toxicity, pharmacokinetics and biodistribution data for this proteinase fraction following a single dose into Sw

16. Mutational and acquired carbapenem resistance mechanisms in multidrug resistant Pseudomonas aeruginosa clinical isolates from Recife, Brazil
An investigation was carried out into the genetic mechanisms responsible for multidrug resistance in nine carbapenem-resistant Pseudomonas aeruginosaisolates from different hospitals in Recife, Brazil. Susceptibility to antimicrobial agents was determined by broth microdilution. Polymerase chain reaction (PCR) was employed to detect the presence of genes enc

17. Antibiofilm, Antioxidant, Antimutagenic Activities and Phenolic Compounds of Allium orientale BOISS.
ABSTRACT This is the first study to investigate the antibiofilm, antioxidant and antimutagenic activities and phenolic compounds of Allium orientale. Antimicrobial activity of ethanolic extracts of A. orientale was determined by a broth microdilution method. Antibiofilm activity was evaluated by microplate biofilm assay. The antioxidant activity was determin

18. Antimutagenic, antiproliferative, and antioxidant effect of extracts obtained from octopus (Paraoctopus limaculatus)
Abstract The search for chemopreventive/chemoprotective compounds in marine organism has been extensively reported; however, the presence of these compounds in octopus has been incipiently explored. In this research, the antimutagenic, antiproliferative, and antioxidant potential of three crude extracts (methanolic, acetonic, and hexanic) from Paroctopus lim

19. In vitro antioxidant, antimutagenic and antiproliferative activities of collagen hydrolysates of jumbo squid (Dosidicus gigas) byproducts
AbstractHydrolysates from two different jumbo squid byproducts (fins and arms), produced by trypsin and protease type XIV were compared on the basis of their antioxidant (DPPH and ABTS radical scavenging assays), antimutagenic (Ames test) and antiproliferative (Transformation cell proliferation in M12.C3F6 murine cells) activities. Jumbo squid arms had highe

20. CHEMICAL CONSTITUENTS, ANTI-INFLAMMATORY, AND FREE-RADICAL SCAVENGING ACTIVITIES OF Guettarda viburnoides CHAM. & SCHLTDL. (RUBIACEAE)
Chemical investigation of Guettarda viburnoides (leaves) led to the isolation of ursolic acid, uncaric acid, secoxyloganin, and grandifloroside, along with a mixture of quercetin-3-O-β-D-galactopyranoside and quercetin-3-O-β-D-glucopyranoside, and of β-sitosterol and stigmasterol. The structures of the isolated compounds were elucidated on the basis of th

21. Desenvolvimento de um quebra-cavacos para a operação de roscamento do aço ABNT 4133 modificado
O setor de óleo e gás vem ampliando seu mercado nos últimos anos devido a uma demanda cada vez maior por recursos de energia. Descobertas na região do pré-sal estão exigindo a prospecção de poços de maior profundidade usando tubos com maior resistência a pressões elevadas e para atuarem em ambientes corrosivos. Todo esse cenário faz com que novos

23. Evaluation of mutagenicity and metabolism-mediated cytotoxicity of the naphthoquinone 5-methoxy-3,4-dehydroxanthomegnin from Paepalanthus latipes
A large number of quinones have been associated with antitumor, antibacterial, antimalarial, and antifungal activities. Results of previous studies of 5-methoxy-3,4-dehydroxanthomegnin, a naphthoquinone isolated from Paepalanthus latipes Silveira, Eriocaulaceae, revealed antitumor, antibacterial, immunomodulatory, and antioxidant activities. In this study, w

24. Transformações do significado de conflito na "História de Florença" de Maquiavel
O estudo da questão do conflito a partir da "História de Florença" nos fornece elementos capazes de mostrar que a reflexão maquiaveliana não se desenvolve de modo tão simples e linear quanto parece nos "Discursos". Com efeito, revelará que a oposição entre dois tipos de conflito - positivo e negativo - descrita nos "Discursos" se define progressivam
