Title: Inhibition of xenoreactive antibodies
Inventor: BYRNE GUERARD W
IPC: A61K47/48
Filed: 1999-04-15
Abstract: One aspect of the present invention relates to methods and compositions for attenuating xenograft rejection by administering, to an animal receiving the xenograft, an amount of a polymer-derivatized xenoantigen (hereinafter "xenopolymer") effective for inhibiting or lessening the severity of hyperacute rejection response (HAR), or other immunological response to the graft, that is dependent on the presence of the xenoantigen on the grafted tissues or cells. In certain enbodiments, the xenopolymer is administered in an amount sufficient to neutralize host antibodies ("xenoreactive antibodies" or "XNA") immunoreactive with the xenoantigen. The xenopolymer may additionally, or alternatively, be used as a tolerogen (or anergen) for the xenoantigen, e.g., able to suppress, to some degree, the production/secretion of XNAs by the immune system of the host.

Title: Monitoring apparatus
Inventor: HASTING ANTHONY PETER MILBURN
IPC: G01N17/00
Filed: 1999-07-07
Abstract: A monitoring apparatus (1) for monitoring soil build-up in a pipe (6) which may form part of a pipework system including a heat exchanger.  The pipework system is used in e.g. the heat treatment of milk and milk products. The monitoring apparatus (1) is in thermal connection with the pipe (6) and includes a body (2) capable of being heated by a heater. The power supplied to the heater is controlled and monitored such that a change in power input to the heater is indicative of a change in heat transfer to a fluid (8) flowing through the pipe (6). The heat from the apparatus (1) causes localised soil build-up in a portion of the pipe (6) near to the heated body (2). The soil build-up is representative of the soil build-up in the heat exchanger. The cleaning of the pipe (6) may be based on the soil build-up indicated by the monitoring apparatus (1).

Patent CA-2336746-A1 (CA)
Inventor: WATERS JAMES L
IPC: G01N27/447
Filed: 1999-07-09
Abstract: The invention combines a capillary electrophoresis (CE) technique for screening complex biological samples with mass spectrometry (MS), to provide a streamlined procedure for identifying and characterizing candidate ligands in a complex biological sample that bind at a selected binding strength to a selected target molecule. The method of the invention advantageously identifies and characterizes tight-binding ligands when high concentrations of weak ligands are present in the sample, which may mask lower concentrations of tight-binding ligands in the sample. The method involves interfacing a capillary from a CE instrument with a post-capillary mass spectrometer to provide direct mass analysis of target/ligand complexes that migrate stably through the CE instrument. All weaker-binding ligands will not be detected during the MS analysis because they dissociate from the target early during the CE run, before reaching and entering the mass spectrometer. Therefore, this method can identify and structurally characterize moderate-to-tight-binding ligands in complex biological samples, even in the presence of high concentrations of weak-binding ligands.

Abstract: A single bolt coupling for the attachment to the end portion of a pipe having a circumferential shoulder or groove in such end portion includes a coupling which receives the end portion of the pipe therein and a circumferential open ended resilient ring accommodated partially in the internal groove adjacent to the end portion of the coupling body which said ring, after the end portion of the pipe is received in the coupling body and advanced toward the center of the coupling body, the ring is expanded, by the larger outer diameter of the pipe, to a larger diameter inside said groove, but the ring by its memory swings back to its original diameter when the two grooves in the end portions of the coupling and the pipe oppositely coincide, and the ring engages opposite grooves in a locking position and the pipe cannot be pulled from the coupling. The coupling is provided with a screw vise mechanism to expand the ring so that, while the pipe is being received by the coupling, the pipe does not encounter the ring at all until the ring is mounted into the groove of the pipe or pipe encounters the ring to desirable minimum extent. The coupling with rings at each end also can couple two plain ended pipes; or the coupling may have a ring at one end and a different type of connector, like threads, a flange, or a set of partially rotatable cammed jaw members at the other end, or a plain opening to make a bell type joint. The coupling can also be used for pipe fittings, hoses, valves, pressure vessels, lids, dead end of pipe, structural pipe, and electrical conduits. The coupling also can be used to make expansion joints in the pipe line to accommodate thermal expansion. Valves may be incorporated into the coupling itself between the ends of the pipes being coupled, or coupling may be incorporated into the valve body as a connecting component in a valve. The coupling is provided with self energizing circumferential diaphragm gasket.
