摘要:
The invention provides a combination of an antibacterial agent and a delivery agent, in which the delivery agent is bonded, or capable of binding, to the antibacterial agent, and in which the delivery agent is capable of binding to one or more structures on a bacterial cell membrane. The invention further provides the use of such combinations in treating or preventing bacterial infections.

A method of reconstructing a3-dimensionalimage in a proton transmission computerised tomography (CT) apparatus is disclosed. The method comprises the creation of a reconstruction matrix. The matrix is created by directing a plurality of particles to traverse the object; and for each particle, measuring the trajectory and energy of each particle before and after it has traversed the object; for each particle, calculating the water-equivalent path length within the object; and for each particle, calculating the positions at which it entered and exited the object; and adding the water-equivalent path length, entry and exit positions to the reconstruction matrix. This procedure is repeated from a plurality of angular positions surrounding an object to be imaged. Then, a spatially varying 2- dimensional filter function is applied to the reconstruction matrix. Subsequently, a correction factor is applied to the filtered reconstruction matrix to at least partially correct for the finite extent of the matrix.

A method is described for producing highly stable silver colloidal solu- tions by reducing silver nitrate with lithium citrate. In the method, the main steps consist of: (a) heating a first quantity of water to a first predetermined temperature; (b) adding a second quantity of silver nitrate to the water; (c) heat- ing the mixture to a second predetermined temperature; (d) adding a third quan- tity of an aqueous lithium citrate solution to the mixture; (e) maintaining the mix- ture at the second predetermined temperature for a predetermined time; and (f) cooling the mixture. The mixing process is accompanied by constant stirring. The colloid exhibits high light-scattering properties and intense SERS or SERRS spectra with low background fluorescence levels and a long shelf life, making it particularly suitable for Raman spectroscopy.

A method for the diagnosis of Type 1 diabetes, or a predisposition towards Type 1 diabetes, or to monitor the efficacy of a therapy to prevent or treat Type 1 diabetes, said method comprising contacting a sample from a subject with a reagent selected from Tetraspanin-7 or a fragment, or a modified form thereof, and detecting an interaction indicative of the presence of an autoimmune response to Tetraspanin-7. Tetraspanin-7 is now understood to be the protein recognised by Glima 38 specific antibodies. Reagents and kits for use in the method and therapies associated with these form further aspects of the invention.

A process of forming a porous polymer template material for use in selectively recovering a metal from a solution of the metal ions comprises polymerising a monomer admixed with a compound of the metal to be recovered, and then treating the polymer to remove the metal compound therefrom. A method of selectively recovering a metal from a solution containing the metal ions comprises contacting a polymer template material formed by a process according to any preceding claim with the solution containing the metal ions, and recovering the metal from the polymer. The invention also proves a polymeric material adapted to capture from a solution containing ions of plural metals a specific one of the metals.

Broadly speaking, embodiments of the present techniques provide a method for harvesting mushrooms which grow in clusters, by determining a picking schedule that maximises the yield while minimising damage to the mushroom or surrounding mushrooms to thereby increase shelf-life.
摘要:
An energy determining apparatus (100) for determining the individual energy of one or more particles of hadron radiation (40) has a main axis (101) for aligning with a general direction of incident particles (40). The apparatus comprises a two-dimensional array of scintillator elements (41) configured to emit a quantity of light in response to energy of one or more incident particles of hadron radiation (40) passing through, or along, that scintillator element (41). Each of the scintillator elements (41) is an elongate element with a longitudinal axis extending parallel to the main axis (101). An array of detectors (44) convert the light from the scintillator elements (41) into electrical signals. A processor (115) is configured to determine a total quantity of light corresponding to energy of a single particle (40) based on outputs of the array of detectors (44).
