Publication number: 20220065865Abstract: The invention relates to a method of treating a cartilage matrix-forming bone tumour and/or a metastatic cancer originating from a cartilage matrix-forming bone tumour, for example chondrosarcoma, in which one or more of an inhibitor of RUNX2 activity, an inhibitor of RUNX2 expression, an inhibitor of YBX1 activity and an inhibitor of YBX1 expression, is administered to a subject in need thereof. The invention also relates to an in vitro method for detecting the presence of a cartilage matrix-forming bone tumour in a subject or the risk of a subject developing a cartilage matrix-forming bone tumour, for example chondrosarcoma, in which the following steps are performed: (i) measuring the expression level of at least one of RUNX2 and YBX1 in a biological sample obtained from a subject, and (ii) comparing the expression level of RUNX2 and/or YBX1 in the biological sample obtained from the subject with the respective expression level of RUNX2 and/or YBX1 in normal cartilage or other biological material.Type: ApplicationFiled: December 23, 2019Publication date: March 3, 2022Inventors: Darrell GREEN, William FRASER

Patent number: 9658202Abstract: A method of identifying a product comprises forming a tagged product by adding to said product a tracer material comprising at least one tracer compound which is acceptable for use as an additive in food and subsequently analyzing a sample of said product to determine the presence of said tracer compound thereby to determine whether said sample is a sample of the tagged product. The method is especially useful for the identification of vegetable oil products from sustainably managed sources. The use of permitted food additives as tracers enables the product to be identified in the supply chain while also allowing it to be used safely in foodstuffs if required.Type: GrantFiled: August 4, 2008Date of Patent: May 23, 2017Assignee: JOHNSON MATTHEY PLCInventors: Darrell Green, Duncan William John McCallien, Christopher Thomas Llewellyn

Patent number: 9156707Abstract: A method of tracing an aqueous liquid, particularly an aqueous urea used for addition to a selective catalytic reduction system to remove NOx from diesel exhaust includes adding a tracer comprising a pre-determined amount of a phenol to the liquid. The liquid can subsequently be identified by reacting a sample with a reagent containing a predetermined amount of 4-aminoantipyrine in the presence of an initiating compound such that the reaction between the reagent and a phenol in the liquid produces a chromophore and measuring the absorbance of the resulting solution of the chromophore.Type: GrantFiled: August 22, 2006Date of Patent: October 13, 2015Assignee: Johnson Matthey PLCInventors: Darrell Green, Andrew West

Patent number: 8330106Abstract: The invention comprises a radiation and contamination monitor for the monitoring of radiation and contamination. The instrument is intrinsically safe and comprises a radiation detector, a power source, a signal processor and a display, said power source, signal processor and display being housed within a sealed instrument housing formed from a non-metallic material which is resistant to static discharge. The detector may be housed in a detachable housing for contamination monitoring.Type: GrantFiled: September 8, 2006Date of Patent: December 11, 2012Assignee: Johnson Matthey PLCInventors: Darrell Green, Colin Cunningham

Publication number: 20090025470Abstract: A method of monitoring the flow of fluid within or from an oil or gas reservoir includes inserting a solid tracer into the reservoir. The tracer comprises at least one metal selected from caesium, niobium, tantalum, tellurium, terbium, lanthanum, gold, iridium, osmium, silver, platinum, palladium, rhenium, ruthenium, rhodium, hafnium, indium, a metal of the Lanthanide series of the periodic table, or a salt thereof. A sample of fluid within or flowing from the reservoir is collected and analysed to determine the amount of the tracer contained in the sample. A perforation tool allows for insertion of the tracer within the formation.Type: ApplicationFiled: March 5, 2007Publication date: January 29, 2009Inventors: Darrell Green, David Stubbs
