Abstract: The present invention is concerned with vaccines and their preparation. An effective long-term immune response, especially in mammals, can be produced using a vaccine comprising an antigen encapsulated in liposomes, a suitable adjuvant and a carrier comprising a continuous phase of a hydrophobic substance. The vaccine is particularly effective in eliciting the production of antibodies that recognize epitopes of native proteins.

Abstract: The present invention relates to medical devices such as endoscopes that may be used to visualize biological material during a medical procedure, such as surgery. In one embodiment, the present invention provides for an endoscope comprising one or more electronic-cameras arranged to create one or more stereo picture pairs to permit quantitative 3-dimensional (3D) imaging and analysis. In another embodiment, the present invention provides a method of imaging comprising using a 3D endoscope with one or more electronic cameras to create one or more stereo picture pairs.

Abstract: A broadband cholesteric optical device such as a polarizer or a spectral filter includes a broadband cholesteric layer, for instance, of a graded pitch type such that the cholesteric pitch increases monotonically from one surface of the film to the other surface. In order to improve the off-axis performance, a compensator is provided in the form of a positive birefringence film whose optic axis is substantially perpendicular to the film. Another negative birefringence film whose optic axis is also perpendicular to the film may also be provided.
