I am working within the newly established Catalyst Lab with Thomson Reuters Global Resources. The focus of this research group is threefold: to foster collaboration, innovation and resource leveraging across the spectrum of the company's Professional (Legal, Tax & Accounting, Scientific) and Markets (Financial, News) business units. We educate Thomson(More)
Helicobacter pylori adhere to Kato III and Hela S3 cells in monolayer cultures. To explore whether cell surface glycoconjugates on these two cell lines mediate binding of H. pylori, various carbohydrates, glycoproteins, and glycolipids were tested to inhibit H.pylori cell adhesion. The adhesion was measured (i) with a urease-based assay and (ii) by cells(More)
The Helicobacter pylori vacuolating cytotoxin or VacA toxin is a major virulence factor in H. pylori infection and type B gastritis. We predicted heparin/heparan sulfate (H/HS) binding properties of the 58-kDa subunit of VacA cytotoxin using bioinformatics tools and showed this by surface plasmon resonance (SPR)-based biosensor studies. Putative H/HS(More)
Cell surface proteins of the human gastric pathogen Helicobacter pylori, reference strain CCUG 17874, were extracted with acid glycine and fractionated by heparin affinity chromatography. The extracts were subsequently analysed using high-resolution two-dimensional gel electrophoresis (2-DE) and immunoblotting. Four proteins of low molecular masses (25-30(More)
Heparan sulphate binding to cells of the gastric pathogen Helicobacter pylori at pH 4-6 is common. Binding was inhibited by various unlabelled sulphated polysaccharides and at high ionic strength and pH, but not by carboxylated or non-sulphated compounds. The inhibition by various sulphated compounds such as dextran sulphate and carrageenans was related to(More)
Heparan sulphate binding to Helicobacter pylori at pH 4 to 5 was inhibited with various sulphated polysaccharides (heparin and chondroitin sulphates, fucoidan, carrageenans and some others), but not by carboxylated or nonsulphated compounds. Heparin binding proteins are exposed on the cell surface.
Information architecture, like information development and delivery, has much in common with its software counterpart. This paper describes how the Rational ClearCase® documentation group developed an information architecture to meet changing industry, corporate, and product requirements. During this work, it became clear that our architecture(More)
Helicobacter pylori is a cause of chronic gastritis and leads to development of atrophy in some cases. There is evidence that the heat shock protein 60 (HSP60) of H. pylori is involved in induction of chronic inflammation. Seroprevalence of IgG antibodies to H. pylori HSP60 in an adult cohort from Saaremaa, Estonia (68 persons, median age 57 years), with a(More)
Cell surface proteins of the human gastric pathogen Helicobacter pylori extracted during different in vitro growth phases were analyzed by one- and two-dimensional gelelectrophoresis (1-DE and 2-DE) and by 2-DE immunoblot. Broth-cultured H. pylori cells were stained with an acridine-orange dye to monitor the morphological status of the organism. In(More)
