Abstract: The invention relates to the use of gene therapy in the treatment of aseptic loosening of orthopaedic prostheses and discloses methods of refixing such prostheses without open revision surgery. In particular, it provides adenoviral vectors and prodrugs for simultaneous, separate or sequential use in the destruction of interface tissue allowing subsequent recementing of loose prostheses in a minimally invasive manner.

Abstract: The invention relates to a bag used for the placement of concrete or grout, either hand placed or pump filled, in and around watercourses. The bags are impermeable and contained in nature, made of biodegradable, degradable or water soluble polymer film, typically made from renewable starch based polymers or water soluble polymers. The bags offer a means of easily and simply placing concrete or grout, safely, cleanly and without risk of contamination to the watercourse or environment from cement leakage, being impermeable in nature, whilst allowing the polymer film to safely degrade, dissolve or disintegrate, in the environment, without the risk of unsightly or environmentally detrimental polythene waste being placed in the watercourse.

Abstract: A ceiling-mounted bicycle storage hoist including a first elongated structural member (36) and a second elongated structural member (38). The first elongated structural member is connected to the second elongated structural member, forming a V-shaped structural assembly spanning at least 1220 mm in one direction, to enable attachment to ceilings comprising wooden joists spaced at 305 mm, 406 mm, 488 mm, or 610 mm intervals. A first, second, and third rope and pulley system are attached to the first and second elongated structural members. The first, second, and third rope and pulley systems converge at a location near the connection between the first and second elongated structural members, enabling a user to control the first, second, and third rope and pulley systems simultaneously. A bicycle may be attached to the first, second, and third rope and pulley systems and hoisted in a horizontal orientation.

Abstract: A scour protection system comprising one or more bags placed in an underwater location to prevent scour caused by the flow of water, wherein the bags can be filled with matter in situ to form interconnecting blocks, and the visible upper surfaces of the bags resemble rocks or other features.

Abstract: A multivalent antigen-binding protein comprises a first Fv fragment bound to at least one further Fv fragment by a connecting structure which links the Fv fragments to each other but which maintains them spaced apart such that the proteins are capable of binding to adjacent antigenic determinants. Typically the connecting structure comprises a spacing polypeptide sequence, which may be about 3 to 16 amino acids in length, connected to a linkage unit which may be a synthetic chemical linker, e.g., a maleimide linker, or is a polypeptide sequence leading from the spacing sequence. In a particularly preferred embodiment, the multivalent antigen binding protein comprises a VH domain having attached to its C-terminal end a V-C joining sequence and an antibody hinge sequence. Preferably one or more of the Fv fragments is a single chain Fv (scFv). The proteins are preferably prepared by recombinant DNA techniques and are useful for in vivo therapeutic and especially diagnostic applications.

Abstract: A method for expressing recombinant molecules in bacterial hosts in a defined medium in the absence of antibiotic selection is disclosed. The method uses an expression vector comprising a regulatable promoter by which the production of foreign proteins may be controlled during the growth phase of the culture, and origin of replication maintaining medium vector copy number and a transcriptional promoter.

Abstract: The invention provides a method for the expression of recombinant molecules in bacterial hosts in a defined medium in the absence of antibiotic selection. The method uses an expression vector comprising a regulatable promoter by which the production of foreign proteins may be controlled during the growth phase of the culture, an origin of replication maintaining medium vector copy number and a transcriptional terminator.

Abstract: The present invention provides humanized antibody molecules (HAMs) having specificity for carcinoembryonic antigen (CEA) and having an antigen binding site wherein at least one of the complementarity determining regions (CDRs) of the variable domains is derived from the mouse monoclonal antibody A5B7 (A5B7 MAB) and the remaining immunoglobulin-derived parts of the HAM are derived from a human immunoglobulin. The HAMs may be chimeric humanized antibodies or CDR-grafted humanized antibodies and are preferably produced by recombinant DNA techniques. The HAMs are useful for in vivo diagnosis and therapy.
