Abstract: Biochemical devices comprising a sensing surface that is at least partially covered by a nanocrystalline metal oxide semiconductor film which provides a recipient surface for immobilizing biochemical species on. The film has a mesoporous surface that gives up to a 1000 increase in biochemical species adsorption when compared to a flat surface. The biochemical devices comprising these surfaces can be optical and electrochemical biosensors and reactors for synthetic or biodegradation reactions.

Abstract: A composition for in vitro and in vivo transfection of vertebrate male germ cells comprises a nucleic acid or transgene, and a gene delivery system, and optionally a protective internalizing agent, such as an endosomal lytic agent, a virus or a viral component, which is internalized by cells along with the transgene and which enhances gene transfer through the cytoplasm to the nucleus of the male germ cell. A method of genetically altering a vertebrate male germ cell in vivo employs a lentiviral-derived vector. A method of substantially depopulating a vertebrate testis employs a combination of a dose of an alkylating agent, such as busulfan, chlorambucil, cyclophosphamide, melphalan, or ethyl ethanesulfonic acid, and a dose of gamma radiation. A pharmaceutical preparation and a transfer kit utilize the composition. A method for introducing a polynucleotide into vertebrate male germ cells comprises the administration of the composition to a vertebrate.

Abstract: A chemoattractant protein called “eotaxin” is capable of attracting eosinophils and of inducing eosinophil accumulation and/or activation in vitro and in vivo. Various types of agents that inhibit or otherwise hinder the production, release or activity of eotaxin may be used therapeutically in the treatment of asthma and other inflammatory diseases.

Abstract: The invention relates to a delivery system for a recipient, the delivery system comprising a transgenic organism containing a vaccine for the recipient, wherein the vaccine is expressed by a gene contained within the transgenic organism, and the vaccine is capable of being transmitted by and from the organism to the recipient, and wherein the vaccine is prepared outside of the recipient, and wherein the recipient is an animal.

Abstract: The invention is related to antibodies, particularly monoclonal antibodies, which recognize particularly epitopes of the intimin protein of enteropathogenic E. coli and enterohemorrhagic E. coli, methods of detecting such E. coli by use of these antibodies, and kits containing these antibodies for diagnosis.

Abstract: A method of imaging molecules of interest within a biological sample includes shining a UV light onto the sample and detecting the molecular UV absorption. Where the molecules of interest are themselves UV absorbers, the intrinsic absorption of those molecules may be used. If the molecules of interest are not good UV absorbers, UV-aborbing tag molecules may be use. The method may be used in molecular imaging devices of all types, and in DNA sequences. A novel diamond-based detector is disclosed which is suitable for many applications.

Abstract: A stent for supporting part of a blood vessel which stent includes a supporting portion around which or within which part of a blood vessel intended for grafting can be placed so that the stent internally or externally supports that part and the supporting portion of the stent is of a shape and/or orientation whereby flow between graft and host vessel is caused to follow a non-planar curve. By maintaining non-planar curvature in the graft itself, favorable blood flow velocity patterns can be achieved through generation therein of ‘swirl’ flow. Failures in such grafts through blockage, kinking or collapse, can be significantly reduced.

Abstract: Method of identifying resistance to Hepatitis C infection wherein the presence of HLA-DRB1*1301-3, HLA-DRB1*1201, HLA-DRB1*1101 or HLA-DRB1*0701 are identified. Peptides capable of modifying immune response and methods of treating Hepatitis C are also disclosed.

Abstract: Concentrator for use with photovoltaic devices includes a waveguide (2) incorporating quantum dots. The quantum dots red-shift the incident radiation to produce red-shifted radiation which is internally reflected within the waveguide (2). A photovoltaic device (10) converts the red-shifted radiation to electrical energy.

Abstract: The invention relates to a delivery system for a recipient, the delivery system comprising a transgenic organism containing a vaccine for the recipient, wherein the vaccine is expressed by a gene contained within the transgenic organism, and the vaccine is capable of being transmitted by and from the organism to the recipient, and wherein the vaccine is prepared outside of the recipient, and wherein the recipient is an animal.

Abstract: Mesoscopic magnetic field sensors which can detect weak magnetic fields (typically 0.05 Tesla) over areas as small as tens of thousands of square nanometers (e.g. 40 nm×400 nm). The combination of enhanced magneto-resistance in an inhomogeneous high mobility semiconductor, having special electrode arrangements, with the use of island lithography, enables the production of special semiconductor/metal nano-composite structures, and has made possible the fabrication of an entirely new type of magnetic field sensor which exhibits very superior magneto-resistive behavior.
