Abstract: Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to assess the severity of a stenosis in the coronary arteries without the administration of a hyperemic agent.

Abstract: An apparatus and method of assessing a narrowing in a fluid filled tube having a fluid flow pressure wave having a backward-originating pressure component and a forward-originating pressure component without taking a flow velocity measurement, comprising: taking pressure measurements in the tube; separating the pressure components into the backward-originating pressure component and the forward-originating pressure component; identifying a time window when the differential of flow velocity (dU) is minimal or absent; and deriving the backward and forward pressure components for pressure measurements taken in at least the time window.

Abstract: The invention provides a method of characterising a DNA sample obtained from a tumour, the method including the steps of: determining the presence or absence of a plurality of base substitution signatures, rearrangement signatures and indel signatures in the sample and copy number profiles for the sample; generating, from the presence or absence of said plurality of base substitution signatures, rearrangement signatures and indel signatures and the copy number profile for the sample, a probabilistic score; and based on said probabilistic score, identifying whether said sample has a high or low likelihood of being homologous recombination (HR)-deficient. Identification of a tumour as HR-deficient may be used to inform treatment choices, for example treatment with a PARP inhibitor or platinum therapy or an anthracycline.

Abstract: The present invention provides methods of characterising a DNA sample obtained from a tumour to produce an interpreted profile of the tumour based on a combination of a range of tests on the tumour, the tests including a selection from: determining a catalogue of base substitution signatures which are present in the sample; determining a catalogue of rearrangement signatures which are present in the sample; determining a catalogue of insertion/deletion signatures which are present in the sample; determining the overall copy number profile in the sample and identifying putative driver mutations present in the sample.

Abstract: The present invention relates to the identification of a number of mutational signatures in patients with cancer. The mutational signatures include new base substitution signatures and rearrangement signatures. The signatures were identified by whole genome sequencing of 560 breast cancers and the application of new and existing mathematical methods to the base substitution and rearrangements found in those cancers.
