    Abstract: Vaccines are provided for treatment of individuals for infections by gram negative bacteria. The vaccines are comprised of live avirulent Salmonella which are able to induce immunity to homologous and to heterologous Salmonella serotypes, and to other gram-negative enteric bacteria. The Salmonella of which the vaccine is comprised possess at least one mutation in a gene which globally regulates other genes, and which also possess a mutation in at least one other of the following type: a mutation either in a gene encoding an enzyme in a lipopolysaccharide synthesis, which results in a reversibly rough phenotype; or in a gene which regulates the synthesis of iron-regulated OMPs, such that the mutation leads to constitutive expression of these proteins. Strains useful for the production of these vaccines are also provided.

    Abstract: An RF probe (20) for use in magnetic resonance applications includes a transmitter coil (24) for transmitting RF energy to excite a specimen (34) and a receiver coil (28) for sensing the RF energy absorbed or emitted by the specimen (34) wherein the receiver coil (28) is electrically decoupled from the transmitter coil (24) through the geometrical shape and positioning of the receiver coil (28) with respect to the transmitter coil (24). The technique includes the concept of physically locating multiple elements of either a transmitter or receiver coil in a non-orthogonal manner such that the net current induced in the receiver coil (28) is equal to zero. In another embodiment, the receiver coil (28) has a primary coil loop (32) for placement immediately adjacent a specimen (34) and a secondary coil loop (30), said receiver coil loops (30, 32) being anti-phase and connected in series and wherein the secondary receiver coil loop (30) may be angularly rotated with respect to the transmit coil (24) in order to achieve a zero net induced current. In still another embodiment, the receiver coil (28) element has a pair of parallel connected anti-phase coil elements (30, 32) and the primary coil element (32) for placement immediately adjacent the specimen (34) has a reduced inductance.

    Abstract: The invention encompasses methods of maintaining desired recombinant genes in a genetic population of cells expressing the recombinant gene. The methods utilize mutant cells which are characterized by a lack of a functioning native gene encoding an enzyme which is essential for cell survival, wherein this enzyme catalyses a step in the biosynthesis of an essential cell wall structural component and the presence of a first recombinant gene encoding an enzyme which is a functional replacement for the native enzyme, wherein the first recombinant gene cannot replace the defective chromosomal gene. The first recombinant gene is structurally linked to a second recombinant gene encoding a desired product. Loss of the first recombinant gene causes the cells to lyse when the cells are in an environment where a product due to the expression of the first recombinant gene is absent. The invention also encompasses methods of creating and isolating mutant cells with the above characteristics. The cells of the invention are useful for commercial production of desired products, for components of vaccines for immunizing individuals, and for release into the environment.

    Abstract: A method to obtain purified, well defined cell populations from intact organs by digestion of the distended organ with suitable proteolytic enzymes in the main lower chamber (101) of the isolator and harvest of cell subpopulation by screening the effluent from treatment of the organ with physiologically compatible medium by a filtration screen (104) permitting the passage of desired cells into the conical upper chamber (105) converging to an outlet port (106), but preventing the passage of larger particles. In this manner, the physical/mechanical disruption of the cell population is unnecessary because of recircularization of the media by input ports (103) which is aided by agitation enhancers (102). The cells are eased out of their structural matrix and harvested directly. Application of this method to the preparation of purified islets of Langerhans from intact pancreas is described.

    Abstract: Disclosed are methods of cell surface activation and inhibition that involve the interaction of an inhibitor of matrix metalloprotease known as TIMP-2, with the enzyme, gelatinase-A (GelA). Critical to the methods of the invention is the discovery of a unique TIMP-2 binding site on the surface of the C-terminal domain (GelA-CTD) of the enzyme, which has been determined to be Asp , but which can also include other residues in the Ge1A-CTD domain with which Asp forms a contiguous surface, namely Gly , Phe , and Tyr . Identification of this binding site provides a useful target for the screening of MMP inhibitors and for prognosis and treatment of diseases in which MMPs are implicated. Compounds which are candidate MMP inhibitors can be structured to competitively inhibit cell surface activation.

    Abstract: There is disclosed an assay method of screening and identification of anti-amebic drugs which utilizes the ability to inhibit anaerobic growth of a novel bacterial mutant that expresses the EhADH2 gene and which bypasses the conventional need for a parasitic culture. The novel mutant, designated E. coli/EhADH2, is cultured under anaerobic conditions, a predetermined or known quantity of the agent to be tested or target compound is combined with the cell culture, and the combination is then monitored to determine the inhibitory effect upon the anaerobic growth of the E. coli/EhADH2 cell mutant.
