Publication number: 20110229559Abstract: Methods of producing a controlled release formulation for an active substance are disclosed, wherein the methods involve dispersing a discontinuous phase comprising an active substance into a continuous phase so as to form a two-phase liquid system comprising droplets of said discontinuous phase, and allowing nanoparticles provided to the two-phase liquid system to congregate at the phase interface to thereby coat the surface of the droplets in at least one layer of said nanoparticles. The methods utilise a concentration of a suitable electrolyte which enhances the nanoparticle congregation such that the coating of nanoparticles on the surface of the droplets presents a semi-permeable barrier to the active substance, or otherwise utilise a amount of the active substance that is greater than the solubility limit of that active substance in the discontinous phase.

Patent number: 7574304Abstract: A method of segmenting chromatin particles in a nucleus of a cell by locating regional minima in an image, computing a zone of influence (ZOI) around each regional minimum, and segmenting a single chromatin blob within each ZOI using a region growing procedure. The method can be used as the basis of a method of qualitatively characterizing the distribution of nuclear chromatin by computing features for individual chromatin particles. Chromatin features can be synthesized from the features of individual particles and particle features can be synthesized into nucleus features and slide features. The method is useful for detecting malignancy associated changes and changes during neoplasia. The method may also be used more generally to assess chromatin patterns in living cells during the cell life cycle. This makes it possible to measure alternations in the evolving patterns that result from pathological or environmental influences.Type: GrantFiled: July 19, 2002Date of Patent: August 11, 2009Assignees: University of Adelaide, University of South Australia, University of Melbourne, Flinders University School of Informatics and Engineering, The University of Queensland, The Commonwealth of Australia (Defense Science & Technology Organisation), Telstra Corporation Limited, Compaq Computer Australia Pty Ltd., RLM Systems Pty Ltd, CEA Technologies Inc.Inventors: Paul Jackway, Andrew Mehnert
