Xyloglucans are the principal glycans that interlace cellulose microfibrils in most flowering plants. The mur3 mutant of Arabidopsis contains a severely altered structure of this polysaccharide because of the absence of a conserved alpha-L-fucosyl-(1-->2)-beta-D-galactosyl side chain and excessive galactosylation at an alternative xylose residue. Despite(More)
This paper investigates whether CiteULike and Mendeley are useful for measuring scholarly influence, using a sample of 1,613 papers published in Nature and Science in 2007. Traditional citation counts from the Web of Science (WoS) were used as benchmarks to compare with the number of users who bookmarked the articles in one of the two free online reference(More)
This article compares the Faculty of 1000 (F1000) quality filtering results and Mendeley usage data with traditional bibliometric indicators, using a sample of 1397 Genomics and Genetics articles published in 2008 selected by F1000 Faculty Members (FMs). Both Mendeley user counts and F1000 article factors (FFas) correlate significantly with citation counts(More)
Porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV), a positive-strand RNA virus that belongs to the Arteriviridae family of Nidovirales, has been identified as the causative agent of PRRS. Nsp1alpha is the amino (N)-terminal protein in a polyprotein encoded by the PRRSV genome and is reported to be crucial for subgenomic mRNA synthesis,(More)
Plant cell walls are composed of a large number of complex polysaccharides, which contain at least 13 different monosaccharides in a multitude of linkages. This structural complexity of cell wall components is paralleled by a large number of predicted glycosyltransferases in plant genomes, which can be grouped into several distinct families based on(More)
The heterotrimeric influenza virus polymerase, containing the PA, PB1 and PB2 proteins, catalyses viral RNA replication and transcription in the nucleus of infected cells. PB1 holds the polymerase active site and reportedly harbours endonuclease activity, whereas PB2 is responsible for cap binding. The PA amino terminus is understood to be the major(More)
Porcine reproductive and respiratory syndrome virus (PRRSV), a member of the Arteriviridae family of Nidovirales, is the causative agent of porcine reproductive and respiratory syndrome, which results in enormous economic losses in the swine industry. As the second protein encoded by the PRRSV genome, nsp1beta cleaves itself from the downstream nsp2 protein(More)
APPL1 is an effector of the small GTPase Rab5. Together, they mediate a signal transduction pathway initiated by ligand binding to cell surface receptors. Interaction with Rab5 is confined to the amino (N)-terminal region of APPL1. We report the crystal structures of human APPL1 N-terminal BAR-PH domain motif. The BAR and PH domains, together with a novel(More)
OBJECTIVES To investigate, in a randomized controlled study, the degree of continence after the creation of orthotopic ileocolonic and ileal neobladders after cystectomy and to explore a possible mechanism for the difference in continence between these 2 types of orthotopic neobladder. METHODS From 2003 to 2007, 71 male patients underwent orthotopic lower(More)
Several bacterial species are capable of using nicotine, the main alkaloid in tobacco plants, as a substrate for growth. The dominant species include members of two genera, Pseudomonas and Arthrobacter. The degradation pathway and genetic structure of nicotine catabolism in Arthrobacter nicotinovorans were recently reviewed (Brandsch Appl Microbiol(More)
