Patent CA-2350829-A1 (CA)
Inventor: MULLER CARSTEN
IPC: A61K35/12
Filed: 1999-04-15
Abstract: Disclosed is a method of obtaining selectable transgenic stem cells of a vertebrate by transfecting a male germ cell with a transfection mixture comprising a nucleic acid construct containing a transcriptional unit of a stem cell-specific promoter, for example, a cyclin A1 promotor, operatively linked to a gene encoding a fluorescent or light-emitting reporter protein.  The transfection mixture is a composition for transfection, in vivo or ex vivo, of a vertebrate's male germ cells, which comprises a nucleic acid or transgene, and a gene delivery system, and optionally a protective internalizing agent, such as an endosomal lytic agent, a virus or a viral component, which is internalized by cells along with the transgene and which enhances gene transfer through the cytoplasm to the nucleus of the male germ cell. In stem cells, other than germ cells, grown in vivo, expression of the reporter gene from a cyclin A1 promoter is facilitated by preventing methylation of promoter DNA by the use of flanking insulator elements in the nucleic acid construct. Alternatively, inhibitors of DNA methylation can be used in an in vitro growth medium. A kit contains components of the transfection mixture. Selectable transgenic stem cells have stably integrated the DNA, and non-human transgenic vertebrates comprise these selectable transgenic stem cells.

Abstract: In a three phase bus protection unit for monitoring fault conditions of an electrical power bus and actuating breakers to disconnect the associated power supply and feeder lines from the bus, there is provided for each line a current sensor responsive to the three phase currents passing through the respective breaker and the unit includes a plurality of current input terminals and a voltage input terminal for receiving the voltage output of a voltage sensor on the bus. A processor element in the unit generates digital data indicative of the instantaneous values of the voltage and of the currents and effects pre-determined algorithmic calculations on the digital values of the voltage and the currents to determine a presence of a fault condition in the current through any one of the breakers. In addition a processor element acts to sum the digital values of the currents to determine that sum of currents flowing into the bus and the sum of currents flowing. In the event that the sum differs from zero, a trip output generator trips all the circuit breakers associated with bus and records data relating to said current values. The unit is arranged such that it can be configured in a first configuration in which each of the three phases of each of up to six of the current sensors is connected to the respective current terminals and the three phases are summed independently and a second configuration in which only one of the phases from each up to eighteen of the current sensors is connected to the respective current terminals and said only one of the phases is summed.

Title: Therapy of respiratory influenza virus infection using free and liposome-encapsulated ribonucleotides
Inventor: WONG JONATHAN P
IPC: C12Q1/70
Filed: 2002-03-21
Abstract: The present invention relates to novel ribonucleotide oligonucleotides (RNOs) that are specifically designed to inhibit viral replication. The RNOs are capable of binding to both the negative and positive strands of influenza RNA segments, thereby inhibiting the virus' ability to produce various viral components, thus inhibiting viral propagation, and effectively killing the virus at the intracellular sites of infection in the respiratory tract. The RNOs provided may act independently, or in combination to optimize their antiviral activity. In addition, the RNOs provided may be formulated in liposomes, which facilitate their therapeutic delivery to intracellular sites of infection, and additionally increase antiviral efficacies.

Title: Ultraviolet area sterilizer and method of area sterilization using ultraviolet radiation
Inventor: DEAL JEFFERY L
IPC: A61L2/28
Filed: 2002-08-27
Abstract: An ultraviolet area sterilizer (UVAS) is mobile or stationary. The UVAS is positioned in a room, such an operating room or intensive care unit. Motion detectors sense movement, to assure that personnel have evacuated the space to be sterilized. Subsequently, UV-C generators, such mercury bulbs, generate UV-C from multiple locations within the room or other enclosed space. Multiple UV-C sensors scan the room, and determine the area reflecting the lowest level of UV-C back to the sensors. The device calculates the time required to obtain a bactericidal dose of UV-C reflected back to the sensors. Once an effective bactericidal dose has been reflected to all the sensors, the unit notifies the operator and shuts down.

IPC: H05B3/03
Filed: 2001-04-17
Abstract: An in situ thermal desorption (ISTD) soil remediation system (20) may be used to remove or reduce contamination within soil (24). Heat may be transferred to the soil (24) from resistively heated, bare metal heater elements (56). The heater elements (56) may be placed directly within the soil (24). Alternately, the heater elements (56) may be suspended within casings (60). The heater elements (56) may be conductive heaters, or the heater elements may be radiative heater elements.  The ISTD soil remediation system (20) may include temperature-resistant, chemical resistant, flexible conduits that transport off-gas removed from the ground to a treatment facility (34). A residence time of off-gas within the conduits may be sufficient to allow the off-gas to cool so that the off-gas may pass to a treatment facility (34) through a manifold and piping made of polymeric material.
