1. New Diesters Derived from Piperine: in silico Study and Evaluation of Their Antimicrobial Potential
Piperine, previously extracted from black pepper (Piper nigrum L.), was used as a precursor for the synthesis of twelve new diester derivatives. The final products were obtained through the bimolecular nucleophilic substitution reaction (SN2) of the alkyl 2-chloroacetates and the salt of piperic acid, obtained from the basic hydrolysis of piperine. The compo

2. Metabolization of Insecticidal Amides from Leaves of Piper tuberculatum by Heraclydes hectorides and Naupactus bipes
Amides have been recognized as potent insecticidal natural products but, despite their variety of targets and mechanisms of action, their metabolic fate in insects is virtually unknown. The currently accepted hypothesis is that specialist herbivores are capable of biotransforming xenobiotics rendering them more polar and excretable while generalist insects d

3. Composição nutricional e valores energéticos determinados com frangos de corte de coprodutos do processamento do etanol de milho
ABSTRACT It was determined by the total collection of excreta method, with broilers from 22 to 32 days of age, the coefficients of apparent metabolism of dry matter, crude protein and crude energy and apparent metabolizable energy corrected for zero nitrogen balance (AMEn) of the ethanol co-products of corn: acid oil and dried distillery grains with soluble

5. Xylanase for meat-type quails from 15 to 35 days old
ABSTRACT The objective of this study was to evaluate the effect of the supplementation of two xylanases in the diet of meat-type quail on performance, morphology of the intestinal mucosa, metabolization of nutrients, and carcass yield. The experimental design was a completely randomized 2×3+1 factorial arrangement [two metabolisable energy reductions (70 an

6. Use of Soy Protein Concentrate in Pre-Starter and Starter Diets for Broilers
ABSTRACT Two experiments were carried out to evaluate the effect of using soy protein concentrate (SPC) in pre-starter and starter diets for broilers. In the first experiment, 600 male Cobb broilers, between one and 40 days of age, were distributed in a completely randomized design, with four treatments and six replications of 25 birds each. Treatments were

7. Enamel and dentine demineralization by a combination of starch and sucrose in a biofilm – caries model
Abstract Sucrose is the most cariogenic dietary carbohydrate and starch is considered non-cariogenic for enamel and moderately cariogenic for dentine. However, the cariogenicity of the combination of starch and sucrose remains unclear. The aim of this study was to evaluate the effect of this combination on Streptococcus mutans biofilm composition and enamel

8. Values of Metabolizable Energy and Metabolization of Nutrients for Slow- and Fast-growing Birds at Different Ages
ABSTRACT Two trials were performed to determine apparent metabolizable energy (AME) and AME corrected for zero nitrogen balance (AMEn) values and coefficients of apparent metabolizability of nitrogen (CAMN) and of ether extract (CAMEE) of slow- and fast-growing broilers (Isa label and Cobb, respectively) fed four different diets between 10 to 17 days or 28 t

9. Comparison of the in vivo and in vitro genotoxicity of glyphosate isopropylamine salt in three different organisms
There is considerable controversy with regard to the genotoxicity of glyphosate, with some reports stating that this compound is non-toxic for fish, birds and mammals. In this work, we used the comet assay to examine the genotoxicity of glyphosate isopropylamine (0.7, 7, 70 and 700 µM) in human lymphocytes, erythrocytes of Oreochromis niloticus and staminal

10. Screening and selection of wild strains for L-arabinose isomerase production
The majority of L-arabinose isomerases have been isolated by recombinant techniques, but this methodology implies a reduced technological application. For this reason, 29 bacterial strains, some of them previously characterized as L-arabinose isomerase producers, were assayed as L-arabinose fermenting strains by employing conveniently designed culture media

11. Exposure to particulate matter 2.5 mM collected at high traffic routes in Rio de Janeiro city: evaluation mutagenic, genotoxic and determination of health risks induced by polycyclic aromatic hydrocarbons / Exposição ao material particulado 2,5 m coletado em vias de alto tráfego da cidade do Rio de Janeiro: avaliação mutagênica, genotóxica e determinação de risco à saúde induzido por hidrocarbonetos policíclicos aromáticos
The mutagenicity of airborne particles from combustion is attributed primarily to polycyclic aromatic hydrocarbons (PAHs). We investigated the mutagenic activity of particulate matter (PM2.5) samples collected from three sites in Rio de Janeiro. Samples were collected using a high-volume sampler at Avenida Brasil, the campus of the Rio de Janeiro State Unive

12. Diauxic growth of Geotrichum candidum and Penicillium camembertii on amino acids and glucose
The purpose of this work was to examine physiological differences between the yeast Geotrichum candidum and the mould Penicillium camembertii, organisms involved in the industrial process of cheese ripening. Three groups of amino acids had previously been characterized, based on their carbon assimilation and dissimilation by the two fungal species. For both
