Patent CA-2243204-A1 (CA)
Inventor: FELBY CLAUS
IPC: D21C5/00
Filed: 1997-02-07
Abstract: A process for production of a lignocellulosic material modified by conjugation thereto of a phenolic substance comprising a substituent which, in the conjugated form of the phenolic substance, is, or may become, negatively or positively charged, respectively, comprises: reacting a lignocellulosic fibre material and the phenolic substance with an oxidizing agent in the presence of an enzyme capable of catalyzing the oxidation of phenolic groups by the oxidizing agent; and reacting together the products of the reactions; with the proviso that the phenolic substance is not a phenolic polysaccharide. A strengthened lignocellulose-based product (e.g. a paper product) may be prepared by a procedure wherein a product produced in accordance with the latter process is treated with a strengthening agent having an ionic charge of sign opposite to that which is conferred on the modified lignocellulosic material by the charge-conferring substituent.

Title: Process of determining the efficacy of drug treatment in hiv infected subjects
Inventor: GOOLSBY CHARLES
IPC: C12Q1/68
Filed: 1997-08-22
Abstract: The present invention provides a process for determining the efficacy of antiviral therapy in an HIV-infected subject receiving such therapy. The process includes the steps of a) detecting the level of transcriptionally active HIV in monocytes of the subject at a plurality of different times, b) comparing the detected HIV levels, and c) correlating changes in the detected HIV levels over time with the therapy. The process can be used to monitor the efficacy of treatment with any anti-HIV agent such as AZT, 3TC, DDc, Indivar, or Saquinavir. Decreases in HIV levels over time indicate an efficacious treatment. Increases in detected HIV levels over time indicate resistance to treatment.

Patent CA-2255188-A1 (CA)
Title: Method and apparatus for multiple stages of mass spectrometry
Inventor: CAMPBELL JENNIFER
IPC: H01J49/42
Filed: 1998-12-02
Abstract: A method of and apparatus for analyzing a stream of ions first subjects a stream of ions to a first mass analysis step, to select ions having a mass-to-charge ratio in a first desired range; this enables a mass analyzer with high resolution to be used. The selected ions are then passed into a radio frequency linear ion trap containing a gas. The trapped ions are caused to collide with the gas, either by being injected with a high axial energy or by application of external excitation to cause fragmentation. Fragment ions of a given mass-to-charge ratio can then be isolated and excited to produce fragments of fragments. This process can be repeated to give multiple steps of mass spectrometry, MS n. The fragment ions, and undissociated precursor ions are then passed out of the linear ion trap and subjected to a further mass analysis step, for example in a time of flight device, to determine the mass spectrum of the ions.

Inventor: CLARKE-POUNDER IAN JAMES HENRY
IPC: D21C9/06
Filed: 1999-04-28
Abstract: A pulp mat is formed on a surface of a permeable rotating drum disposed in a pressurized liquid filled washing apparatus. Pressurized washing liquid is delivered under the force of gravity or a hydrostatic head from a wash liquid reservoir. The wash liquid reservoir includes both wash liquid and gas supplied from a filtrate reservoir. The gas/liquid interface in the wash liquid reservoir is hydraulically disposed above the top of the washer vat to thereby provide a hydrostatic head between the wash liquid reservoir and the washer vat. The interface is monitored and used to control the speed of the rotating drum. In the event the gas/liquid interface rises above a predetermined optimum value for the current operating speed of the drum, the speed of the drum is increased in order to avoid mat collapse and optimize washing efficiency. In the event the gas/liquid interface drops below a predetermined optimum level, the speed of the drum is reduced to increase washing efficiency.
