M1 protein and Protein H are surface proteins simultaneously present at the surface of certain strains of Streptococcus pyogenes, important pathogenic bacteria in humans. The present study concerns the structure, protein-binding properties and relationship between these two molecules. The gene encoding M1 protein (emm1) was found immediately upstream of the(More)
BACKGROUND/AIMS Recent reports have suggested that Helicobacter pylori infection induces the mucosal antibiotic peptide human beta defensin 2 (HBD-2). Therefore, the present study investigated mRNA and peptide expression of four different defensins in the upper gastrointestinal tract in patients with H pylori positive and negative chronic gastritis.

The influence of high dose intake of ascorbic acid on the urinary excretion of oxalate was investigated in five healthy male volunteers. Oxalate was measured by a newly developed specific method using isotachophoresis. With intakes of 10 g ascorbic acid (5 X 2 g daily for 5 days; four subjects) mean urinary oxalate excretion was enhanced from about 50 mg to(More)
A total of 305 Ixodes ricinus ticks collected from three areas of Thuringia in central Germany were investigated for infection with Borrelia burgdorferi sensu lato species and Anaplasma phagocytophila. Overall, 11.1% were infected with Borrelia burgdorferi and 2.3% with Anaplasma phagocytophila. Adult ticks showed a significantly higher rate of infection(More)
Outwardly rectifying K(+) channels determine the membrane conductance and influence the proliferation rate of glial progenitor cells. To analyze the molecular identity and the functional role of K(+) channels in glial progenitors of mouse brain, expression of shaker-type Kv1 genes was studied at three levels: (1) presence of Kv1 mRNAs, (2) biosynthesis of(More)
BACKGROUND Conflicting data exist about proteinuria in inflammatory bowel diseases. It is still unclear whether the occurrence of proteinuria in inflammatory bowel disease patients is an extra-intestinal manifestation of disease or the result of adverse effects to medication, especially to aminosalicylates (ASA). METHODS A total of 95 patients (51 with(More)
We investigated the ability of liposomes to deliver the immunosuppressive agent cyclosporine A (CsA) to the cornea, anterior sclera, aqueous humor, and vitreous in rabbit eyes. One drop (10 microliters) of liposome-encapsulated CsA (CsA-LIP) or olive oil drops containing an equivalent concentration of CsA (CsA-DR) were administered at 15-minute intervals(More)
PURPOSE To study the effects of different formulations of topical cyclosporine (Cyclosporin A [CsA]) on corneal allograft rejection in a rat model. METHODS Female Lewis rats received penetrating keratoplasties from female Wistar-Furth donors. A total of 78 allogeneic grafts were performed. An additional 15 syngeneic grafts (Lewis) were used as technical(More)
The molecular basis of capacitative (or store-operated) Ca2+ entry is still subject to debate. The transient receptor potential proteins have been hypothesized to be structural components of store-operated Ca2+ channels and recent evidence suggests that Trp3 and its closely related homolog Trp6 are gated by the N-terminal region of the inositol(More)
