1. A influência da piperina na biodisponibilidade de fármacos: uma abordagem molecular
Piperine is the major alkaloid of Piper nigrum Linn., used as a spice and in folk medicine. We present a molecular docking study supporting experimental data on the enhancement in bioavailability of propranolol, theophylline, phenytoin, nevirapine, nimesulide, pyrazinamide, carbamazepine, and spartein in the presence of piperine. The complex formed with pipe

2. Azopolymers and Applications of Orientational Effects in Liquid Crystal / Azopolímeros e aplicações em efeitos de competição de orientação de cristais líquidos
Neste trabalho foi feito o estudo do efeito de orientação de moléculas de cristal líquido (5CB) em superfícies recobertas com fotopolímeros. Estudamos o processo de alinhamento fotoinduzido às moléculas de cristal líquido, de forma a caracterizar a intensidade de energia de ancoramento em função da energia de luz incidente e da concentração de c

3. Project guidelines for urban settlements considering environmental assessment methods. / Diretrizes para projetos de loteamentos urbanos considerando os métodos de avaliação ambiental.
As many world-wide developed assessment methods for sustanability of isolated buildings and their constituting systems performance, new environmental assessment systems have recently been proposed, taking into account neighborhood, land sub-division and urbanistic issues. They integrate principles of smart growth, sustainable development and green building,

4. Efeitos de superfície nas propriedades térmicas e dinâmicas de filmes de cristais líquidos esméticos. / Surface effects on the thermal and dynamical proprieties of smectic liquid crystal filmes.
The thermal and dynamical properties of free-standing films are strongly dependent on the boundary conditions and the presence of an external field. Using distinct theoretical models and the dynamic light scattering experimental setup, we study the surface and external field effects on the relaxation dynamics, fluctuation-induced interaction energy, and phas

5. Sistemas químicos integrados via complexos de rênio(I) e rutênio(II) na conversão de energia / Chemical integrated systems via rhenium and ruthenium complexes on energy conversion
The focus of this work is on two chemical integrated systems: dye-sensitized solar cells, Dye-Cells®, and photosensors based on rhenium(I) compounds. Novel ruthenium(II) compounds were synthesized, characterized and investigated as dye-sensitizers. The results of solar cells sensitized by cis-[(H3BCN)2Ru(dcbH2)2], H3BCN- = cyanoborohydride, dcbH2 = acid-4,4

6. Influence of the adsorption energy on the dielectric contribution to the anchoring energy of nematic liquid crystals
The influence of the ionic adsorption on the anchoring energy of a nematic liquid crystal sample is investigated. We determine the behavior of the anchoring energy as a function of the thickness of the sample, and as a function of the adsorption energy of ions. We show that the contribution to the anchoring energy, due to ionic adsorption, can be of the same

7. A soluble domain of the membrane-anchoring chain of influenza virus hemagglutinin (HA2) folds in Escherichia coli into the low-pH-induced conformation.
The extensive refolding of the membrane-anchoring chain of hemagglutinin (HA) of influenza virus (termed HA2) in cellular endosomes, which initiates viral entry by membrane fusion, suggests that viral HA is meta-stable. HA2 polypeptide residues 38-175 expressed in Escherichia coli are reported here to fold in vivo into a soluble trimer. The structure appears

8. Metal-hydrogen bridge bonding of hydrocarbons on metal surfaces
Molecular orbital studies implicate multicenter metal-hydrogen-carbon interactions as contributors to the bonding of chemisorbed hydrocarbons on clean metal surfaces. The most stable geometries appear to be those that achieve the maximum multicenter bonding to the coordinately unsaturated metal atoms in the vicinity of the anchoring metal-carbon interaction.

9. Analysis of the C-Terminal Membrane Anchor Domains of Hepatitis C Virus Glycoproteins E1 and E2: toward a Topological Model
The hepatitis C virus (HCV) glycoproteins E1 and E2 should be anchored in the viral membrane by their C-terminal domains. During synthesis, they are translocated to the endoplasmic reticulum (ER) lumen where they remain. The 31 C-terminal residues of the E1 protein and the 29 C-terminal residues of the E2 protein are implicated in the ER retention. Moreover,

10. Lipoprotein lipase (LpL) on the surface of cardiomyocytes increases lipid uptake and produces a cardiomyopathy
Lipoprotein lipase is the principal enzyme that hydrolyzes circulating triglycerides and liberates free fatty acids that can be used as energy by cardiac muscle. Although lipoprotein lipase is expressed by and is found on the surface of cardiomyocytes, its transfer to the luminal surface of endothelial cells is thought to be required for lipoprotein lipase a

11. Structure of the Disordered C Terminus of Rab7 GTPase Induced by Binding to the Rab Geranylgeranyl Transferase Catalytic Complex Reveals the Mechanism of Rab Prenylation*
Protein prenylation is a widespread process that involves the transfer of either a farnesyl or a geranylgeranyl moiety to one or more C-terminal cysteines of the target protein. Rab geranylgeranyl transferase (RabGGTase) is responsible for the largest number of individual protein prenylation events in the cell. A decade-long effort to crystallize the cat

12. Dynamics and molecular interactions of linker of nucleoskeleton and cytoskeleton (LINC) complex proteins
The linker of nucleoskeleton and cytoskeleton (LINC) complex is situated in the nuclear envelope and forms a connection between the lamina and cytoskeletal elements. Sun1, Sun2 and nesprin-2 are important components of the LINC complex. We expressed these proteins fused to green fluorescent protein in embryonic fibroblasts and studied their diffusional m
