Patent CA-2425202-A1 (CA)
Inventor: DIAMOND DON J
IPC: A61K39/25
Filed: 2001-10-22
Abstract: The invention provides peptides which are immunogenic epitopes recognized by CD8+ class I MHC restricted cytotoxic T-lymphocytes of patients harboring latent cytomegalovirus (HCMV) infection. The peptides are capable of activating CTL in the absence of active viral replication, and thus are useful for eliciting a cellular immune response against HCMV by normal and immunodeficient subjects. Vaccines against HCMV, with and without adjuvants, and immunological and diagnostic reagents are disclosed.

Abstract: A gas separation membrane is formed from a copolyimide produced by copolymerization of monomers which include o-tolidine sulfone, at least one other hydrophilic diamine and 2,2-bis(3,4-dicarboxyphenyl) hexafluoropropane dianhydride. One or more additional aromatic dianhydrides can optionally be included. The novel membrane exhibits an excellent combination of high selectivity of gases to be separated from a gas mixture, high permeability and strong solvent resistance to hydrocarbon chemicals. The membrane is therefore useful in separating gases from gas mixtures in which vapor or liquid hydrocarbon contaminants are present, for example in the separation of carbon dioxide from methane and/or nitrogen in the purification of natural gas.

Title: Method and system for determining the acceptability of signal data collected from a prothrombin time test strip
Inventor: KERMANI MAHYAR Z
IPC: G01N33/52
Filed: 2003-08-29
Abstract: A method for determining the acceptability of signal data collected from a prothrombin time (PT) test strip includes collecting PT signal data from an assay area and control areas of the PT test strip. Relationships between PT signal data collected from the assay area and PT signal data collected from each of the control areas (e.g., a ratio of post-peak pseudo-slopes) are then ascertained. A determination is subsequently made, based on the relationships, as to whether the PT signal data collected from the assay area is acceptable or not for use in calculating a PT and/or an International Normalization Ratio (INR). This determination can include, for example, comparing the relationships to at least one predetermined threshold limit. A prothrombin time (PT) monitoring system includes a PT test strip and a device. The PT test strip includes an assay area and a control area. The device (e.g., a portable hand-held meter) includes an optical measurement means (e.g., an LED/photo-detector pair) for measuring an optical property (e.g., absorption) of the assay area and control areas, an analog-to-digital converter module, a microprocessor module and a memory module. The optical measurement means, analog-to-digital converter module, microprocessor module and memory module are adapted to (i) collect PT signal data from the assay area and control areas; (ii) ascertain at least one relationship between PT signal data collected from the assay and control areas and (iii) determine, based on the at least one relationship, whether the PT signal data collected from the assay area is acceptable.

Abstract: A communication protocol based upon the Asymmetric Digital Subscriber Line (ADSL) protocol developed for telephone communications is used for two way transmission of data between a downhole logging device and a surface device.  The total available bandwidth for a pair of conductors is determined by the length of the conductors and the choice of conductors ( operational mode) of a conventional 7 conductor wireline. The available bandwidth is partitioned into channels with a bandwidth of 4.3125kHz, each of the channels carrying a portion of the data. A contiguous subset of the channels is used for downward communication (Down channel) and another subset is used for upward communication (Up channel). The bit loading is dynamically determined based upon monitoring of the noise level. Optionally, more than one mode of the 7 conductor wireline may be used.
