Patent CA-2377400-A1 (CA)
Inventor: KNAPP FRANCESCO
IPC: G05D23/13
Filed: 2000-07-06
Abstract: A thermostatic mixing valve includes a body (1), inlets (2) and (3) for intake of hot water and cold water and a discharge outlet (4) for delivery of mixed water. A mixing chamber (7) is within the body (1) and is defined by a perimeter wall member (8) that houses a slide valve (9) which slidably moves in the mixing chamber so as to control the opening and closing of the inlets to the mixing chamber (7). A thermostatic element (18) is mounted to control motion of the slide valve (9). A partition (10) is mounted in the mixing chamber (7) between the inlets. A cross passage (11) allows water from one inlet to pass the partition toward the discharge outlet (4). The mixing chamber has an inclined surface (14) to direct water from the other inlet toward the cross passage to promote mixing of the hot and cold water.

Title: Thermo-optic switch having fast rise-time
Inventor: HUANG LEE L
IPC: G02F1/313
Filed: 2000-07-27
Abstract: A thermo-optic switch is operated in a novel near-impulse mode in which the drive pulse width is shorter than twice the diffusion time of the switch. Th e drive pulse width is less than the rise time of the steady-state optical response and also less than the rise time of the deflection efficiency response to the applied drive pulse. The drive pulse can further include a sustaining segment following the initial short pulse segment, if it is desir ed to maintain the switch in an ON state for a longer period of time. A number of additional techniques are described for further reducing the response time o f the switch. An array of thermo-optic switches operated in this manner can fo rm a display which, due to the fast individual switch rise times, can operate a t an overall fast refresh rate.

Abstract: Peptide ligands having affinity for IgG or for serum albumin are disclosed.  Also disclosed are hybrid molecules comprising a peptide ligand domain and an active domain. The active domain may comprise any molecule having utility as a therapeutic or diagnostic agent. The hybrid molecules of the invention may be prepared using any of a number techniques including production in and purification from recombinant organisms transformed or transfected with an isolated nucleic acid encoding the hybrid molecule, or by chemical synthesis of the hybrid. The hybrid molecules have utility as agents to alter the elimination half-times of active domain molecules. Elimination half-time is altered by generating a hybrid molecule of the present invention wherein the peptide ligand has binding affinity for a plasma protein. In a preferred embodiment, a bioactive molecule having a short elimination half-time is incorporated as or into an active domain of the hybrid molecules of the invention, and the binding affinity of the peptide ligand domain prolongs the elimination half-time of the hybrid as compared to that of the bioactive molecule.

Title: Improved inhibition of graft versus host disease
Inventor: SPANER DAVID
IPC: A61K35/12
Filed: 2001-01-26
Abstract: The development of graft versus host disease in a mammalian patient undergoi ng cell transplantation therapy for treatment of a bone marrow mediated disease , is prevented or alleviated by subjecting at lest the T-cells of the allogene ic cell transplantation composition, in admixture with red blood cells of the donor, extracorporeally, to oxidative stress, in appropriate dosage amounts,  such as bubbling a gaseous mixture of ozone and oxygen through a suspension of the T-cells. The process may also include irradiation of the cells with UV light, simultaneously with the application of the oxidative stress. The oxidative stress induces reduced inflammatory cytokine production and a reduced proliferative response in the T-cells.

Patent CA-2401913-A1 (CA)
Inventor: KUTZKO JOHN D
IPC: G16H70/20
Filed: 2002-09-06
Abstract: A method, apparatus and system for use in treating a patient receiving an antineoplastic drug to optimize therapy and prevent an adverse drug response.  This system employs surrogate markers or indicators including blood levels of the antineoplastic drug to determine the next required dose for a patient. Since the surrogate markers are employed as a percent change in status, virtually any indicator can be used. Surrogate markers could include any measure of the effectiveness of the antineoplastic drug's action. Given the effectiveness of the antineoplastic drug's action relative to the surrogate markers, a change in antineoplastic drug dose is calculated by the system. Conversely, by employing this system, one could determine the expected result of the antineoplastic drug dose change on the surrogate markers.
