G protein-coupled receptors (GPCRs) catalyze nucleotide release in heterotrimeric G proteins, the slow step in G protein activation. G i/o family proteins are permanently, cotranslationally myristoylated at the extreme amino terminus. While myristoylation of the amino terminus has long been known to aid in anchoring G i proteins to the membrane, the role of(More)
Crystal structures of Galpha(i) (and closely related family member Galpha(t)) reveal much of what we currently know about G protein structure, including changes which occur in Switch regions. Galpha(t) exhibits a low rate of basal (uncatalyzed) nucleotide exchange and an ordered Switch II region in the GDP-bound state, unlike Galpha(i), which exhibits(More)
The topic of this review is a summary of the photonics research currently performed at the Material Science and Chemical Engineering Department at Politecnico di Torino, with an emphasis on novel tellurite glasses and nanocluster doped silica for photonics. The fabrication and characterization of novel tellurite glasses and their optical fibers, with the(More)
OBJECTIVE To analyze the long-term curative effect of endoscopic sinus surgery. METHOD One hundred and twenty-eight cases (180 sides) of chronic sinusitis and nasal polyps were treated with FESS, 80 side (64 cases) were elected randomly to deal with the anatomical variation of middle and inferior turbinate and nasal septum during the operation(More)
