Patent CA-2331787-A1 (CA)
Inventor: CLARK SCOTT
IPC: G01N21/21
Filed: 1999-05-13
Abstract: This invention is directed to an optically-based method and system for analyte detection using solid phase immobilization, specific analyte labels adapted for signal generation and corresponding processes for the utilization thereof. The enumeration detection method disclosed herein narrows the area for signal observation, thus, improving detectable signal to background ratio. The system is comprised of a platform/support for immobilizing a sample stage having a labeled sample (analyte complex) bound thereto, a radiation source, an optical apparatus for generating and directing radiation at said sample and a means for data collection and analysis. Upon engagement of the system, the sample generates a signal capable of differentiation from background signal, both of which are collected and imaged with a signal detector that generated a sample image to a data processing apparatus. Said apparatus receives signal measurements and, in turn, enumerates individual binding events. Generated signal may be increased via selected mass enhancement. The invention, enumeration assay methodology detecting individual binding events, may be used, for example, in analyses to detect analyte or confirm results in both research, commercial and point of care applications.
Patent CA-2333452-A1 (CA)
Inventor: ROTELIUK LUCHY D
IPC: A61B5/028
Filed: 1999-06-07
Abstract: The cardiac ejection fraction (EF) is estimated based on the parameters of a model of an indicator (such as thermal) dilution through the heart. A channel model is defined by an upstream indicator injector, such as a heater, positioned preferably in the right atrium/ventricle and a downstream indicator concentration sensor, such as a thermistor. The preferred model is a lagged normal transfer function, which has as one of its output parameters the indicator decay constant .tau. of the blood channel. The heart rate (HR) is also measured. The ejection fraction (EF) is then calculated continuously as EF = 1-exp(-60/(.tau.*HR)).  The cardiac output (CO) is also estimated in the model, preferably based on an estimate of the zero-frequency gain of the lagged normal transfer function. End diastolic volume (EDV) is then also calculated continuously as a function of CO, HR and EF. In applications where the step response of the indicator concentration sensor is slow relative to the indicator decay, the transfer function Hs of the sensor is determined ahead of time. Parameters characterizing Hs are then stored in a memory device and the measured transfer function data is scaled by Hs prior to modelling to provide the most accurate EF estimate.

Title: Compositions for rapid and non-irritating transdermal delivery of pharmaceutically active agents and methods for formulating such compositions and delivery thereof
Inventor: PETTERSSON BERNO
IPC: A61K36/00
Filed: 1999-07-07
Abstract: Pharmaceutical compositions for the transdermal administration of a medicament or other active agent by topical application or the composition to the skin of humans or other animals are described. Methodology for formulating such compositions which provide for very rapid uptake of the medicament and transmigration into and through the skin to either fatty tissues or the vascular system, while minimizing irritation to the skin and/or immunological response, is based on a transdermal delivery system (TDS) wherein the medicament is modified to form a true solution in a complex formed from particular solvents and solvent and solute modifiers in combination with skin stabilizers. Uptake of the medicament is further facilitated and made more rapid by including Forskolin or other source of cellular energy, namely induction of cAMP or cGMP. Selection of specific solvents and solvent and solute modifiers and other functional ingredients and the amounts thereof are chosen such that there is a balance between the sum of the mole-moments [(molar amount of each individual ingredient) X (dipole moment of that ingredient)] of the delivery system and the sum of the molar moments of the composition in which the medicament is dissolved. Preferably, the van der Waals forces of the delivery system is also similarly matched to the van der Waals forces of the total composition, namely, delivery system plus active agent.

Title: System and method for protection of digital works
Inventor: TA THANH T
IPC: G06F21/10
Filed: 2001-03-23
Abstract: A method of protecting a digital work uses a blind transformation function to transform an encrypted digital work into encrypted presentation data. The originator's digital content is protected in its original form by not being decrypted. This method enables the rendering or replay application to process the encrypted document into encrypted presentation data without decrypting it first. Encrypted presentation data is then decrypted just before it is displayed to the user. The blind transformation function is a function of the original transformation function. For example, the blind transformation function may be a polynomial of the original transformation function.  Alternatively, both the blind transformation function and the original transformation function may be any multivariate, integer coefficient affine function.

Title: Prevention and treatment of viral infections
Inventor: TODD WILLIAM J
IPC: C12N15/63
Filed: 2000-03-09
Abstract: Methods and compositions are disclosed for the prevention, treatment, and cure of viral infections. The invention comprises encrypting or regulating the genetic codes of toxins so that toxins are expressed only within virus-infected cells. Three embodiments of the invention include: I) placing a toxin gene under the control of a virus-specific regulatory sequence; II) using an antisense sequence that is copied into a positive messenger RNA for a toxin in the presence of RNA-dependent RNA polymerase; and III) negative DNA toxin codes that are copied to positive toxin codes in the presence of virus-specific complementary sequences that can act as primers for DNA polymerase.  In each case, toxin is expressed only within cells infected by a virus having a virus-specific factor (e.g., an inducer, an enzyme, or a nucleic acid sequence) necessary for the expression of the toxin, resulting in death of the infected cell prior to production of infectious viral progeny, thereby terminating the infectious cycle. These methods are also applicable to kill cancer cells associated with such viruses.
