1. Evaluation of pathogen P21 protein as a potential modulator of the protective immunity induced by Trypanosoma cruzi attenuated parasites
BACKGROUND TcP21 is a ubiquitous secreted protein of Trypanosoma cruzi and its recombinant form (rP21) promotes parasite cell invasion and acts as a phagocytosis inducer by activating actin polymerisation in the host cell. OBJECTIVE Our goal was to evaluate if the additional supplementation of rP21 during a prime/boost/challenge scheme with T. cruzi TCC

2. Studying the electrical, thermal, and photocatalytic activity of nanocomposite of polypyrrole with the photoadduct of K3[Fe(CN)6] and diethylenetriamine
Abstract The present work reports the synthesis of nanocomposite of polypyrrole with [Fe(CN)3(dien)].H2O photoadduct via in-situ oxidative chemical polymerisation. Photoadduct was synthesised by irradiating an equimolar mixture of K3[Fe(CN)6] and diethylenetriamine (dien) using Osram photo lamp. The successful synthesis of photoadduct was proved by Elemental

3. Effect of the properties of natural resin binder in a high friction composite material
In this paper, a high-friction composite material based on the combination of binder, friction modifiers, fibers and fillers is investigated. In the binder, up to 20% of phenol are replaced by cardanol with various weight ratios of 100/0, 95/5, 90/10, 85/15, 80/20. Cardanol may react both through the phenolic group and the double bond of the side chain yield

4. Hidrogeles microestructurados de acrilamida y determinación de su capacidad de absorber agua y etanol
This paper reports the synthesis of nanostructured hydrogels of acrylamide by a two-step polymerisation process. The first step is performed by inverse microemulsion polymerization (water-in-oil) of N-isopropylacrylamide (NIPA), with these particles then added to aqueous solutions of acrylamide (AM), adding a crosslinking agent. The polymerization reaction i

5. Influência da simulação da temperatura dental no grau de conversão e cinética de polimerização de cimentos resinosos autodesisivos expostos a diferentes modos de ativação. / Simulating the influence of temperature on dental conversion degree and kinetics of polymerisation of resin cements autodesisivos exposed to different modes of activation.
Este estudo avaliou o grau de conversão (GC) de duas marcas comerciais de cimentos resinosos autoadesivos (CRA), polimerizados em diferentes valores de temperaturas dentais e sob diversas condições de ativação, utilizando Espectroscopia Infravermelha com Transformada de Fourier (FTIR). RelyX U100 (U100, 3M ESPE) e Maxcem Elite (MX, Kerr Corporation) for

6. Aggregative adherent strains of Corynebacterium pseudodiphtheriticum enter and survive within HEp-2 epithelial cells
Corynebacterium pseudodiphtheriticum is a well-known human pathogen that mainly causes respiratory disease and is associated with high mortality in compromised hosts. Little is known about the virulence factors and pathogenesis of C. pseudodiphtheriticum. In this study, cultured human epithelial (HEp-2) cells were used to analyse the adherence pattern, inter

10. Imobilização e detecção de biomoléculas em matrizes de poli (ácido 4-hidroxifenilacético) : aplicações no desenvolvimento de genossensores
Eletrodos modificados com filmes poliméricos são matrizes eficientes para a imobilização de biomoléculas. Devido à funcionalização aniônica ou catiônica da superfície, eles promovem a repulsão eletrostática de interferentes e interação eficiente com a biomolécula imobilizada. Desta forma, os EQM impulsionam grande avanço no desenvolvimento d

11. Infiltration condition and mouldability diagram in resin injection moulding
This paper deals with the modelling of injection moulding processes taking into account the deformability of the preform and the polymerisation of the resin. The coupled flow-deformation problem in the infiltrated and dry region is formulated with the corresponding boundary conditions and with the proper evolution equations determining the motion of the boun
