Abstract: A method of inducing partial or complete immunity to an infectious disease in a mammal comprising providing to the mammal for oral consumption an effective amount of a protein complex comprising five monomeric fusion proteins.

Abstract: A DNA construct that encodes, when expressed in a plant cell, a protein complex comprising five monomeric fusion proteins; where each fusion protein comprises a cholera toxin B subunit linked at the 3? end of the cholera toxin B subunit to a first immunogenic antigen from a causal factor of a first infectious mammalian disease other than cholera; and where the antigen elicits a protective response to the disease.

Abstract: A plant-based edible vaccine against autoimmune disease prepared by expressing a CTB-autoantigen chimeric gene construct in plant cells and transgenic plants is disclosed. DNA constructs, expression vectors comprising a nucleotide sequence that encodes a CTB-autoantigen chimeric gene, which are optimized for expression in plants, are described.

Abstract: An interferometric geophone includes a freely-falling reference mass and an interferometric arrangement to measure motion of a surface to which the geophone is attached. The mass may fall through an evacuated chamber. A carriage arrangement may reposition the reference mass for another fall. The reference mass has top and bottom retro-reflectors. The interferometric arrangement includes a laser and a beam-splitter that divides the laser beam into two beams directed toward the top and bottom of the reference mass by partially reflecting surfaces on prisms or mirrors. When the beam encounters the first face of each prism or a first mirror it is split again. One of the split beams is directed toward the falling retro-reflector; the other beam passes through the prism or mirror and encounters the second face. The retro-reflector returns the first split-beam to the second face via a lens arrangement.
