The Front Cover exhibits a photo of the famous Ponte Vecchio (Old Bridge) on Arno River, as tribute to city Florence and its University, where all research has been carried out. Allegorically, Old Bridge reflecting water surface represents two faces sugar derivative which rearrangement may take place: from top (the or bottom mirrored Bridge). picture created by skill Dr. Marco Bonanni.

At the time of Leonardo da Vinci, numerous landfalls and transversal passages along Arno made it easily crossable navigable in Tuscany, from Valdichiana to coast. In order develop a specific knowledge such elements, restore valuable analytical tile for recognition territorial heritage related Leonardo’s hydraulic design, this chapter presents work carried out by authors map ports, ships, passes...

B2-1 (cytohesin-1) is a member of a group of proteins (including ARNO and ARNO3) that are all of similar size and domain composition. The three proteins contain an N-terminal coiled-coil domain, followed by a Sec7 and a pleckstrin homology (PH) domain. While it is well established that the Sec7 domain functions as a guanine nucleotide exchange factor (GEF) for ADP-ribosylation factors (ARFs) an...

The vascular endothelium responds to infection by destabilizing endothelial cell-cell junctions to allow fluid and cells to pass into peripheral tissues, facilitating clearance of infection and tissue repair. During sepsis, endotoxin and other proinflammatory molecules induce excessive vascular leak, which can cause organ dysfunction, shock, and death. Current therapies for sepsis are limited t...

The ADP ribosylation factor (ARF) GTP binding proteins are believed to mediate cytoskeletal remodeling and vesicular trafficking along the secretory pathway. Here we show that ARF6 is specifically associated with dense-core secretory granules in neuroendocrine PC12 cells. Stimulation with a secretagogue triggers the recruitment of secretory granules to the cell periphery and the concomitant act...

The pleckstrin homology (PH) domains of the homologous proteins Grp1 (general receptor for phosphoinositides), ARNO (Arf nucleotide binding site opener), and Cytohesin-1 bind phosphatidylinositol (PtdIns) 3,4,5-trisphosphate with unusually high selectivity. Remarkably, splice variants that differ only by the insertion of a single glycine residue in the beta1/beta2 loop exhibit dual specificity ...
