The basis of differentiation of Pseudomonas aeruginosa into the 17 serotypes of the International Antigenic Typing Scheme is differences in an outer membrane glycolipid, lipopolysaccharide (LPS). This observation, together with the high toxicity and pyrogenicity of LPS, has led to the search for alternative "common" antigens for use as vaccines. The relation between the major outer membrane pro...

The translocase components of the mitochondrial outer membrane (Tom) are essential for the transfer of preproteins from the cytosol to the mitochondria. At least nine Tom components have now been identified and they fall into two categories; receptor components and components of the General Import Pore (GIP). The receptor components most likely diffuse laterally in the membrane and deposit prep...

Bid is a proapopotic activator protein of the Bcl-2 family that plays a pivotal role in controlling mitochondrial outer membrane permeabilization during apoptosis. Here, we characterized the interaction of fluorescently labeled truncated Bid (tBid) with a mitochondria-like supported lipid bilayer at the single-molecule level. The proteins observed at the membrane exhibited a very wide range of ...

1 Preface Outer billiards is a basic dynamical system defined relative to a convex shape in the plane. B.H. Neumann introduced outer billiards in the 1950s, and J. Moser popularized outer billiards in the 1970s as a toy model for celestial mechanics. Outer billiards is an appealing dynamical system because of its simplicity and also because of its connection to such topics as interval exchange ...

A numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. The slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges on the bottom of the outer cylinder which is designated as θ=0°. The outer cylinder is partially opened at the top with a width of W=30mm and is kept at constant t...

In river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. A helical motion results, causing erosion of the outer side of the bend. Installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. In th...

helicobacter pylori infections are accompanied with the release of some antigenic material into the stool. outer membranes proteins (omp) are among the major antigens of bacteria, which in comparison with other bacterial constituents have less cross-reactivity. in this study, omp of h. pylori were isolated from 11 clinical isolates and rabbit antiserum against them was used to detect possible a...
