Abstract:
The invention provides chimeric proteins comprising a non-toxic Pseudomonas exotoxin A sequence and a Type IV pilin loop sequence, wherein the Type IV loop sequence is inserted within the non-toxic Pseudomonas exotoxin A. The invention also provides polynucleotides encoding the chimeric proteins, and compositions comprising the polynucleotides or the chimeric proteins. The invention also provides methods for using the chimeric proteins, polynucleotides and compositions of the invention.

Abstract:
The invention provides mutated Pseudomonas exotoxins (PE) that have reduced immunogenicity compared to PEs containing the native sequence. The PEs of the invention have one or more individual mutations of positions of the native sequence of PE that reduce antibody binding to one or more PE epitopes. Nucleic acids encoding the mutated PEs, chimeric molecules comprising them, compositions comprising the chimeric molecules and methods of using them, are also provided.
Abstract:
A collapsible stroller like device is described. The device includes a base portion to permit a child to be pushed or pulled across the snow or other surface.
Abstract:
A propulsion device which takes advantage of the fact that the mass of an object will decrease if the energy density of the object changes rapidly. The energy density is changed by causing rapid changes in stress on the bonds between the atoms of the object. By this means, the mass of a rotating (20) object is decreased to one side of its axis of rotation, creating an unbalanced centrifugal force that acts on the rotating object as a propulsive force in the direction from the lower mass half toward the higher mass half. The propulsive force is used to propel an object or hold an object in position in opposition to an outside force or provide mechanical energy for a purpose such as the generation of electricity.
