BACKGROUND The Thiol-specific antioxidant (TSA) is an antigen of Leishmania major which is believed to be the most promising molecule as a vaccine candidate against leishmaniasis. OBJECTIVES In this study, we investigated the protective efficacy of TSA-based DNA vaccine against L. major infection. MATERIALS AND METHODS Recombinant plasmid construction TSA (pcTSA) was prepared and transfecte...

For adsorbates confined within a single, sufficiently narrow cylindrical pore, no phase transitions occur because the system is too close to the one-dimensional limit. We study the influence of intermolecular correlations between adsorbed molecules in neighboring cylindrical pores, using molecular simulation. For a simple model of methane in the molecular sieve ALPO4-5, we find that a phase tra...

A solvent-free method was proposed to upgrade the biomass-derived compound 5-hydroxymethylfurfural (HMF). The oxidation of HMF produce 2,5-furandicarboxylic acid (FDCA) has been examined in presence O2 without addition solvent and base. Different from conversion aldehyde group on as initial step H2O solvent, hydroxyl first oxidized FDCA finally generated solvent. role is replenish consumption a...

Following the synthesis of aligned single-wall carbon nanotubes in the channels of AlPO4-5 zeolite single crystals, we present the first X-ray diffraction and diffuse scattering results. They can be analysed in terms of a partial filling of the zeolite channels by nanotubes with diameter around 4Å. The possible selection of only one type of nanotube during the synthesis, due to the constraints ...

The syntheses of thermally stable chromium-incorporating hexagonal mesoporous aluminophosphate and cubic Cr-MCM-48 have been reported. Characterization of the catalysts was made using low angle XRD, N2 adsorption, UV-VISDRS, thermal analysis, ICP-AES and ESR. Mesoporous Cr-AlPO4 and Cr-MCM-48 catalysts have been found to be active for the vapour phase oxidation of toluene with molecular oxygen....

Molecular sieves and zeolites are materials whose crystalline frameworks form nanometer or subnanometer pores. A variety of different crystal structures are known having a range of pore sizes. Because the pore sizes are usually smaller than 2 nm, they are classified as microporous materials. Synthesis of microporous materials is usually conducted by the high temperature treatment (80-200 °C) of...

To evaluate the sedimentation of aluminium phosphate [AlPO4] and ferrous [Fe3(PO4)2] precipitates in sodium carboxymethylcellulose (Na-CMC) biopolymer at different temperatures, batch-wise precipitation tests AlPO4 Fe3(PO4)2 solutions Na-CMC were carried out temperatures 30, 40 50oC. The objective was to determine On-set Sedimentation Rate (OSR) Volume Ratio (SVR) metal phosphates. Fixed volume...
