    Abstract: A method of calibrating an instrument for surgical intervention is provided. The instrument to be calibrated has a tip at a distal end thereof and a navigation array that is spaced from the distal end and is detectable in space. The navigation array has a fixed spatial and angular relationship with the tip. The method comprises the steps of: placing a calibrator on the tip of the instrument such that the tip is positioned within the calibrator at a known displacement from the centre of the calibrator, the calibrator having a circular shape and being detectable as a single point in space; detecting the position of the navigation array and the centre of the calibrator; and determining the position of the centre of the calibrator relative to the navigation array, thereby calibrating the position of the tip of the instrument relative to the navigation array. There is also provided a calibrator for use in such a method.

    Inventor: Marit Otterlei

    Abstract: The present invention provides an agent, or composition containing an agent, for use in treating or preventing hypercytokinemia in a subject resulting from cytokine release from non-proliferating immune cells in blood, wherein the agent comprises: (i) an oligopeptidic compound comprising a PCNA interacting motif and a domain that facilitates the cellular uptake of said compound, wherein the PCNA interacting motif is X1X2X3X4X5 (SEQ ID NO: 1) and wherein: X1 is a basic amino acid; X2 is an aromatic amino acid; X3 is an uncharged amino acid other than an aromatic amino acid, Glycine (G) and Proline (P); X4 is any amino acid other than Proline (P), an acidic amino acid or an aromatic amino acid; and X5 is a basic amino acid or Proline (P); or (ii) a nucleic acid molecule comprising a sequence encoding the oligopeptidic compound of (i). In certain aspects the agent and compositions of the invention may be used as single agents. In other aspects of the invention agents and compositions of the invention may be used in conjunction with one or more additional active agents, such as kinase inhibitors.
