1. Arranjos supramoleculares de oligodeoxinucleotídeos e fragmentos de bicamada catiônica: preparação, caracterização e atividade imunoadjuvante / Supramolecular assemblies of oligodeoxynucleotides and cationic bilayer fragments: preparation, characterization and immunoadjuvant activity
A interação entre fragmentos de bicamada (BF) de brometo de dioctadecildimetilamônio (DODAB) e um mononucleotídeo-modelo (deoxiadenosina monofosfato, dAMP) ou um oligodeoxinucleotídeo-modelo (5- AAAAAAAAAA-3, poli(dA)) ou um oligodeoxinucleotídeo terapêutico (5- TTGACGTTCG -3, CpG) foi investigada por turbidimetria, espalhamento de luz dinâmico, espe

2. Supramolecular assemblies of drugs in synthetic lipid and/ or polyelectrolytes: colloid stability and in vitro activity / Arranjos supramoleculares de drogas em lípides sintéticos e/ ou polieletrólitos: estabidade coloidal e atividade in vitro
Formação, estabilidade coloidal e atividade in vitro contra Candida albicans dos arranjos supramoleculares compostos por drogas, lípides catiônicos e/ ou polieletrólitos foram sistematicamente avaliados através de espalhamento de luz dinâmico para tamanho de partículas, análise de potencial-zeta, espectrofotometria UV-visível, efeitos de droga sobr

3. Optimum adsorption of phospholipid bilayer on silica and reconstitution of receptor function. / Adsorção ótima de bicamada fosfolipídica sobre sílica e reconstituição do reconhecimento receptor-ligante
The general objective of this project was to continue evaluating the suitability of amphiphiles that aggregate in aqueous solution forming bilayers, to cover surfaces of silica. A secondary objective pursued was to promote the reconstitution of the receptor-ligand function, having as a model the monosialoganglioside GM1 and the enterotoxin of the choleric vi

4. Cationic bilayers over silica: adsorption and colloidal stability at low ionic strength / Bicamadas catiônicas em sílica: adsorção e estabilidade coloidal a baixa força iônica
The study of adsorption of model-membranes on the surface of solid partic1es is an important line of research in rapidly developing research areas such as biosensors design, building up of immunological kits or design ofbiocompatible materiais. In this work, interactions between hidrophilic silica particles and cationic liposomes made up of dioctadecyldimeth

5. Interações entre bicamadas lipídicas e interfaces hidrofóbicas / Interactions between lipid bilayers and hydrophobic interfaces
Determinations of surface tension (γ) at the air--water interface, contact angles (Θ), and in and ex-situ ellipsometric mean thickness (d) were used to study the interaction between dioctadecyldimethylammonium bromide (DODAB) small vesicles and spin-coated polystyrene sulfate (PSS) films on silicon wafers. Upon the adition of NaCl (50 mM final conc

6. Interactions between cationic liposomes and drugs or biomolecules
Multiple uses for synthetic cationic liposomes composed of dioctadecyldimethylammonium bromide (DODAB) bilayer vesicles are presented. Drugs or biomolecules can be solubilized or incorporated in the cationic bilayers. The cationic liposomes themselves can act as antimicrobial agents causing death of bacteria and fungi at concentrations that barely affect mam

7. Preparação e caracterização de dispersões de anfifílicos sintéticos / Preparation and characterization of dispersions of synthetic amphiphiles
Dioctadecyldimethylammonium chloride (DODAC) liposomes with 0.51µ mean external diameter and sharp phase transitions were obtained by chloroform vaporization and compared with (small) sonicated DODAC vesicles. Sucrose was impermeant through large DODAC liposomes and sonicated vesicles and was used for internal volume determinations. The apparent interna

8. Incorporation of the major outer membrane protein of Neisseria gonorrhoeae in saponin-lipid complexes (iscoms): chemical analysis, some structural features, and comparison of their immunogenicity with three other antigen delivery systems.
We incorporated the major outer membrane protein (PI) of Neisseria gonorrhoeae into immunostimulating complexes (iscoms) and examined some analytical, physicochemical, and immunological properties of these structures. The immunogenicity was compared with that of three other PI-containing structures, i.e., liposomes, outer membrane complexes produced by the b

9. In Vitro Antifungal Activities of Inhibitors of Phospholipases from the Fungal Pathogen Cryptococcus neoformans
Secreted phospholipase B is a proven virulence factor for the pathogenic fungus Cryptococcus neoformans and exhibits three phospholipase activities in the one protein. These are phospholipase B (PLB), lysophospholipase (LPL), and lysophospholipase transacylase (LPTA). Our aim was to investigate the feasibility of using this enzyme as a target for antifungal
