1. Applied methodology to obtain an information system from a hub port. / Metodologia aplicada para obter um sistema de indicadores de porto concentrador de carga.
A política é umbilicalmente ligada à atividade humana e está associada às questões de educação. As carências desse conjunto de diretrizes nas áreas de transportes somadas às lacunas da literatura e fragilidades desses sistemas prejudicam também os sistemas energéticos e ambientais. No Brasil as combinações desses problemas causam significativa

2. FEZ1 protein : little organizational structure, activities related to elements of the cytoskeleton and generation of the "flower like" phenotype / A proteina FEZ1 : pouca organização estrutural, atividades associadas a elementos do citoesqueleto e formação do fenotipo "flower like"
FEZ1 was identified first as a orthologue of C elegans UNC-76 protein, that plays functions related to neuronal development in this worm. Subsequent studies, shows FEZ1 functions in neuronal development process, cell polarization, transport mechanisms associated to kinesins and vesicular and mitochondrial transports. Other works showed that FEZ1 superexpress

3. Two size-selective mechanisms specifically trap bacteria-sized food particles in Caenorhabditis elegans
Caenorhabditis elegans is a filter feeder: it draws bacteria suspended in liquid into its pharynx, traps the bacteria, and ejects the liquid. How pharyngeal pumping simultaneously transports and filters food particles has been poorly understood. Here, we use high-speed video microscopy to define the detailed workings of pharyngeal mechanics. The buccal cavit

4. Neural regulation of sex pheromone biosynthesis in Heliothis moths
Pheromone biosynthesis in females of Heliothis zea is regulated endogenously by a neuropeptide produced in the subesophageal ganglion. We have found that the ventral nerve cord must be intact for normal induction of pheromone biosynthesis and that pheromonotropic activity is associated with extracts of the abdominal nerve cord, but only during the period whe

5. The Lipid Binding Pleckstrin Homology Domain in UNC-104 Kinesin is Necessary for Synaptic Vesicle Transport in Caenorhabditis elegansD⃞V⃞
UNC-104 (KIF1A) is a kinesin motor that transports synaptic vesicles from the neuronal cell body to the terminal. Previous in vitro studies have shown that a Dictyostelium relative of UNC-104 transports liposomes containing acidic phospholipids, but whether this interaction is needed for the recognition and transport of synaptic vesicles in metazoans remains

6. A Multifunctional ATP-Binding Cassette Transporter System from Vibrio cholerae Transports Vibriobactin and Enterobactin
Vibrio cholerae uses the catechol siderophore vibriobactin for iron transport under iron-limiting conditions. We have identified genes for vibriobactin transport and mapped them within the vibriobactin biosynthetic gene cluster. Within this genetic region we have identified four genes, viuP, viuD, viuG and viuC, whose protein products have homology to the pe

7. In Vivo Effects of Clostridium perfringens Enteropathogenic Factors on the Rat Ileum
An experimental model was established using the terminal ileum of the rat for characterizing and studying the effects of crude cell-free extract from Clostridium perfringens upon physiological and histological parameters involved in the transport process. Further work was done with the model system using purified enterotoxin (protein) from the cell extract.

8. Proteolytic processing of the 600 kd low density lipoprotein receptor-related protein (LRP) occurs in a trans-Golgi compartment.
The low density lipoprotein receptor-related protein (LRP) is a cell surface glycoprotein that binds and transports plasma lipoproteins enriched in apolipoprotein E. It is synthesized in the endoplasmic reticulum as a transmembrane glycosylated precursor that migrates with an apparent molecular mass of about 600 kd on SDS-polyacrylamide gels. After it reache

9. The Karyophilic Properties of Human Immunodeficiency Virus Type 1 Integrase Are Not Required for Nuclear Import of Proviral DNA
Integrase (IN) is a key component of the preintegration nucleoprotein complex (PIC), which transports the retroviral genome from the cytoplasm to the nucleus of newly infected cells. Retroviral IN proteins have intrinsic karyophilic properties, which for human immunodeficiency virus type 1 (HIV-1) are currently attributed to regions that display sequence hom

10. Cloning and functional characterization of a mammalian zinc transporter that confers resistance to zinc.
A cDNA encoding a zinc transporter (ZnT-1) was isolated from a rat kidney cDNA expression library by complementation of a mutated, zinc-sensitive BHK cell line. This cDNA was used to isolate the homologous mouse ZnT-1 gene. The proteins predicted for these transporters contain six membrane-spanning domains, a large intracellular loop and a C-terminal tail. Z

11. Crystal structure of human sex hormone-binding globulin: steroid transport by a laminin G-like domain
Human sex hormone-binding globulin (SHBG) transports sex steroids in blood and regulates their access to target tissues. In biological fluids, SHBG exists as a homodimer and each monomer comprises two laminin G-like domains (G domains). The crystal structure of the N–terminal G domain of SHBG in complex with 5α–dihydrotestosterone at 1.55 Å resolution

12. Importin α transports CaMKIV to the nucleus without utilizing importin β
Ca2+/calmodulin-dependent protein kinase type IV (CaMKIV) plays an essential role in the transcriptional activation of cAMP response element-binding protein-mediated signaling pathways. Although CaMKIV is localized predominantly in the nucleus, the molecular mechanism of the nuclear import of CaMKIV has not been elucidated. We report here that importin α is
