1. Propriedades de vesículas unilamelares gigantes / Properties of Giant Unillamelar Vesicles
The stability of giant unilamellar vesicles (GUVs) has been monitored by phase contrast and fluorescence microscopy, using sugar gradients, sodium 1,3,6,8 pirene tetrasulfonate (PTS) as fluorescent probe, 1,1-dimethyl-4,4-bipiridinium chloride (MV) as fluorescence quencher and 2-(12-(7-nitrobenz-2-oxa-1,3-diazol-4-il) amino) dodecanoyl-1-hexadecanoyl-sn-glic

2. Determinação do espectro UV-B utilizando o radiômetro GUV: aplicação a medidas realizadas em Punta Arenas / Determination of UV-B spectra using the GUV multichannel radiometer: aplication to the measurements made at Punta Arenas
Este trabalho apresenta um modelo semi-empírico para reconstituir o espectro de irradiância global na faixa de radiação solar correspondente ao UV-B, a partir de dados de irradiância global obtidos com o radiômetro GUV (Ground-based Ultraviolet Radiometer). O modelo emprega simulações computacionais usando o modelo de transferência radiativa STARSCI

3. Transporte de ácidos graxos e prótons através de bicamadas lipídicas planas. / Fatty acid and proton transport across lipid bilayer planar membranes.
O presente estudo tentou elucidar diversos aspectos da transferência de ácidos graxos (AG) através da matriz lipídica utilizando, como modelo experimental, a bicamada lipídica plana (BLP). Bicamadas lipídicas planas (BLPs) foram formadas pelo método de MUELLER et alii (1963) em um orifício circular (0.4 a 2.4 mm de diâmetro) de um frasco de polietil

4. Profilin Interaction with Phosphatidylinositol (4,5)-Bisphosphate Destabilizes the Membrane of Giant Unilamellar Vesicles
Profilin, a small cytoskeletal protein, and phosphatidylinositol (4,5)-bisphosphate [PI(4,5)P2] have been implicated in cellular events that alter the cell morphology, such as endocytosis, cell motility, and formation of the cleavage furrow during cytokinesis. Profilin has been shown to interact with PI(4,5)P2, but the role of this interaction is still poorl

5. A minimal system allowing tubulation with molecular motors pulling on giant liposomes
The elucidation of physical and molecular mechanisms by which a membrane tube is generated from a membrane reservoir is central to the understanding of the structure and dynamics of intracellular organelles and of transport intermediates in eukaryotic cells. Compelling evidence exists that molecular motors of the dynein and kinesin families are involved in t
