Abstract: The present invention provides an in vitro method for determining the resistance or sensitivity of a cell line or patient sample to a deoxyribonucleoside kinase-dependent drug, wherein the method comprises the steps of: (i) treating a patient sample or cell line, or a portion thereof, with a deoxyribonucleoside kinase-dependent drug; (ii) lysing the cells of the patient sample or cell line from step (i); (iii) optionally, mixing a portion of the cell lysate from step (ii) with a bioluminescent reporter bacteria incorporating a gene coding for deoxyribonucleoside kinase; (iv) mixing a portion of the cell lysate from (ii) with a bioluminescent reporter bacteria incorporating a gene coding for a deoxyribonucleoside kinase and a deoxyribonucleoside kinase transcription promoter; (v) mixing a portion of the cell lysate from step (ii) with a bioluminescent reporter bacteria incorporating a gene coding for a deoxyribonucleoside kinase, a deoxyribonucleoside kinase transcription promoter and a dephosphorylating agent

Abstract: Magnetic particles are distributed across a fluid flow by applied magnetic field to interact with a test substance in fluid. Alternatively or additionally, particles, which may be magnetic, are combined with cells and energy, e.g. ultrasonic energy, is applied to cause the particles to create a lysate. Alternatively or additionally, the size of a quantity of magnetic particles is assessed by its impact on the tuning mechanism of a controlled oscillator that is affected by the particles.

Abstract: A method of forming a workpiece (18) comprises: holding the workpiece adjacent a mould (20); using a laser (30) to heat at least a part of the workpiece to a temperature sufficient induce superplasticity; and applying a fluid pressure to the workpiece, so that it takes the shape of the mould. This has the advantage that the superplastic properties of the material can be used to form the workpiece precisely to the required shape, without needing to heat all of the processing chamber to the superplastic temperature. Before using the laser to heat the workpiece to its superplastic temperature, the laser can be used to heat the whole of the workpiece to a substantially uniform temperature to anneal it. Similarly, after using the laser to superplastically form the workpiece, the laser is used to heat the whole of the workpiece to a substantially uniform temperature to remove any residual stresses.

Abstract: A method for detecting Helicobacter pylori in a subject's gastroenteral tract involves measuring a change in resistance of an electronic or electrochemical sensor, notably a polypyrrole film, on exposure to gas from the subject's lungs and/or stomach. Depending on the magnitude of the change (if any) a positive or negative result is indicated visually by electronics means. Two sensors are used, one of which receives a sample of gas which has passed through an amonia-absorbing means to provide a corrected baseline value for the ammonia. The invention also provides apparatus suitable for carrying out the method.
