Abstract: The present invention relates to a new synthetic process in which an alkyne and an azide react to form a radioisotopic bioconjugate construct. The reaction is particularly useful for producing compounds for use in imaging and radiotherapy applications. The present invention also provides bioconjugate labels and further relates to the use of these compounds in diagnostic and therapeutic methods. In addition, the invention provides a related process for introducing a radioisotopic halogen atom into a terminal alkyne.
Abstract: One embodiment of the invention provides a method for performing a supra-threshold test of sensitivity across a visual field of a subject. The method includes presenting a stimulus at each location of a set of locations spread across the visual field and obtaining for each stimulus a result indicating whether or not the stimulus was seen by the subject. The method further includes determining for each location whether or not to re-present a stimulus at that location, wherein for a given location, the determining involves combining results obtained from multiple locations. These multiple locations are defined by a cluster associated with the given location, with the cluster being determined based on the paths of optic nerve fibre bundles across the visual field.

Abstract: Methods and apparatus for optimising, improving or maximising the efficiency of an acousto-optic lens (AOL) system are disclosed. Data relating to efficiency is used to select drive frequencies of the acousto-optic devices (AODs) forming the AOL, thereby both increasing the usable field of view and reducing a prior art patternation problem. Preferably according to the invention, drive frequencies are selected that maximise efficiency of transmission through the AOL. When scanning, the centre of each scan is optimised to be of maximum efficiency.

Abstract: This invention relates to the production of biomaterials with variable stiffness by subjecting a gel which varies in at least one dimension to plastic compaction. These biomaterials may be useful, for example, for the directional control or guidance of cells within tissue equivalent implants.
Abstract: A method for assessing prognosis in an individual suffering from liver failure, which method comprises detecting endotoxin in the individual, for example by determining the neutrophil function in the individual. The method can be used to determine whether there is an increased risk of infection in the individual, an increased risk of organ failure in the individual, an increased risk of mortality in the individual and/or an increased risk that the individual will not respond positively to treatment with an immunosuppressive agent, a steroid or an antibiotic.

Abstract: Methods, systems and apparatus for manipulating electromagnetic radiation such as laser beams. A method and apparatus for correcting magnification chromatic aberration utilises one or more dispersive lenses such that long wavelength components are magnified less than short wavelength components. A telecentric relay is preferred to achieve this aim. Further, the use of polarisers to block the undesired zeroth order components of diffraction emanating from acousto-optic deflectors (AODs) is disclosed. Furthermore, specific designs of AOD including narrow transducer AODs which produce a diverging acoustic wave and AODs having two transducers and a selection switch are disclosed.

Abstract: The present invention provides a method of registering image data for a series of images acquired over a period of time. The images may be acquired from a medical imaging device, such as an MRI scanner. The method allows image-by-image registration to a partially compressed dataset in which motion artifacts are suppressed in a series of target images generated to resemble the original dynamic data. The registration process is refined with each iteration of the process. The method uses Principal Component Analysis which allows accurate registration to be performed without the need to make any assumptions about pharmacokinetic model parameters, which not only avoids the problems of accurate model-fitting but permits the use of much larger target areas of the dataset.
Abstract: The present invention relates to use of ornithine in the manufacture of a medicament for use in combination with at least one of phenylacetate and phenylbutyrate for preventing or treating liver decompensation or hepatic encephalopathy. The invention also relates to use of at least one of phenylacetate and phenylbutyrate in the manufacture of a medicament for use in combination with ornithine for preventing or treating liver decompensation or hepatic encephalopathy.
Abstract: The present invention relates to a method for modifying binocular images, for example, to manipulate the attention of viewers. The binocular images may be for 2D or 3D scenes. The method modifies a left image destined for a left eye and a right image destined for a right eye, by modifying a portion of the left image by adjusting a visual characteristic of the portion in a first direction by a first defined value and modifying a corresponding portion of the right image by adjusting the visual characteristic of the corresponding portion in the opposite of the first direction by a second defined value. A system with an image modification means for modifying binocular images, an apparatus for displaying modified binocular images, a signal and medium for carrying/storing modified binocular images, and a computer program for modifying binocular images are also disclosed.
Abstract: The present invention provides a T-cell receptor (TCR) which binds to a peptide from the cytomegalovirus (CMV) phosphoprotein pp65 having the amino acid sequence NLVPMVATV (SEQ ID No. 1) when presented by a major histocompatability complex (MHC) molecule. The present invention also provides a nucleotide sequence encoding such a TCR, a vector comprising such a nucleotide sequence and its use to produce a CMV-specific T-cell. The present invention also provides the use of CMV-specific T-cell for cellular immunotherapy.
Abstract: An optimized coding sequence of human blood clotting factor eight (VIII) and a promoter may be used in vectors, such as rAAV, for introduction of factor VIII, and/or other blood clotting factors and transgenes. Exemplary of these factors and transgenes are alpha-1-antitrypsin, as well as those involved in the coagulation cascade, hepatocye biology, lysosomal storage, urea cycle disorders, and lipid storage diseases. Cells, vectors, proteins, and glycoproteins produced by cells transformed by the vectors and sequence, may be used in treatment.

Abstract: A surgical clip (5) is provided for clipping a tubular structure (9) in vivo to ligate the tubular structure. The clip comprises first and second clip portions (6, 7). A hinge portion (8) is provided connecting the clip portions together and to enable the clip portions to be hinged together from an open clip condition to a closed clip condition thereby to ligate a tubular structure placed between the clip portions. A lock is provided for locking the clip portions together in the closed clip condition. In the closed clip condition the clip has a substantially smooth external profile, for example including blunt ends (21), so as to reduce the possibility of the clip (in use) eroding surrounding tissue structures.
