Title: Preparation of protein/polysaccharide conjugate vaccines using homobifunctional and heterobifunctional vinylsulfones
Inventor: LEES ANDREW
IPC: A61K47/48
Filed: 1997-05-09
Abstract: A method is disclosed for producing conjugates, and preferably protein/polysaccharide conjugates. In this process, the polysaccharide is reacted with a reagent so as to provide a functional group on the polysaccharide molecule. Once the functional group is in place, the polysaccharide is reacted with a homobifunctional or heterobifunctional vinylsulfone to produce a vinylsulfone derivatized polysaccharide. Thereafter, the vinylsulfone derivatized polysaccharide is reacted with a protein to produce the conjugate. If desired, the protein may be derivatized with a functional group prior to the conjugation reaction step. In an alternative embodiment, the protein may be functionalized with a reactive group and then derivatized with the vinylsulfone group to produce a vinylsulfone derivatized protein. This protein may then be reacted with a polysaccharide to produce the conjugate. Optionally, the polysaccharide may be functionalized with a reactive group prior to the conjugation reaction. As another alternative, the polysaccharide may be derivatized directly with a pendant vinylsulfone of the cross-linking agent. The vinlysulfone derivatized polysaccharide may then be coupled to the protein (which may or may not be functionalized). In a similar manner, the protein may be derivatized directly with a pendant vinylsulfone of the cross-linking agent and then coupled to a polysaccharide molecule (which may or may not be functionalized).

Title: Electrosurgical instrument and method of use
Inventor: BENDEREV THEODORE V
IPC: A61B18/14
Filed: 1997-05-15
Abstract: This invention is an electrosurgical instrument (10) for sequentially cutting and coagulating tissue, including methodology for electrosurgical procedures incorporating principles of the inventive instrument. The instrument comprises a cutting electrode (18) connectable to a first power source (22b) having a first power signal sufficient to cut tissue, and a coagulating electrode (20) connectable to a second power (22a) source having a second power signal sufficient to coagulate tissue. The electrodes may be separated by an electrical insulator (36) to maintain the electrodes in a spaced relationship such that the coagulating electrode can immediately follow the cutting electrode during movement of the instrument, thereby providing sequential cutting and coagulating of tissue. Methods for providing an electrosurgical procedure include providing the instrument with power delivery to the electrodes. The cutting electrode receives a power signal sufficient to cut tissue and the coagulating electrode receives a power signal sufficient to coagulate tissue. The distal ends of the electrodes are introduced to tissue and moved therethrough with a single stroke to thereby cut tissue followed by simultaneous coagulation. The electrodes may be formed of differing cross section configurations, and may be vertically offset to maximize cutting and coagulation of tissue. An in-dwelling dispersible electrode (100) may be utilized to concentrate electrosurgical energy at a desired tissue site.

Patent CA-2262033-A1 (CA)
Inventor: BABCHIN ALEXANDER JOSEPH
IPC: B01J19/08
Filed: 1999-02-16
Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of one kilohertz to 30 megahertz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to any chemical reaction process exhibits growth in the real part of conductivity relative to low frequency value is the subject of this patent.

Title: A method, apparatus & computer program product for selecting a predictor to minimize exception traps from a top-of-stack cache
Inventor: DAMRON PETER C
IPC: G06F9/38
Filed: 1999-07-19
Abstract: Apparatus, methods, and computer program products are disclosed that improve the operation of a computer that uses a top-of-stack cache by reducing the number of overflow and underflow traps generated during the execution of a program. An exception history is maintained that tracks recent occurrences of overflow and underflow exception traps.
