Abstract: Oligonucléotides et analogues oligonucléotidiques pouvant avoir une action réciproque non codante avec l'ARN messager du virus du papillome. De tels oligonucléotides ou analogues oligonucléotidiques peuvent servir au diagnostic et à la thérapeutique ainsi qu'à des fins de recherche. Selon des modes de réalisation préférés, l'oligonucléotide ou l'analogue oligonucléotidique est hybridable avec un ARN messager provenant d'un virus du papillome, peut inhiber la fonction de l'ARN, et est donc utile à la thérapie des infections provoquées par un tel virus du papillome. Selon un mode de réalisation préféré, on cible des parties du virus du papillome pour une attaque non codante. On peut donc obtenir les oligonucléotides préférables, c'est-à-dire ceux qui s'hybrident avec les ARN messagers E2, E1, E7, ou E6-7.
Patent CA-2082070-C (CA)
Title: Branch resolution via backward symbolic execution
Inventor: SITES RICHARD L
IPC: G06F9/44
Filed: 1992-03-03
Granted: 1998-02-17
Abstract: Possible values for a computed destination address of an execution transfer instruction are found by a backward search through a flowgraph of a program. During the search, a symbolic expression for the destination address is successively modified to reflect the effect of each prior instruction until the symbolic expression represents an absolute or program-counter relative address, or until the search can no longer continue. The search can no longer continue, for example, when an instruction is reached that affects the value of the expression in an indefinite way. When backward symbolic execution reaches the entry point of a block in the flowgraph, backward symbolic execution proceeds backward to each predecessor block that has not already been examined for the execution transfer instruction. Therefore multiple definite values as well as a value of "unknown" may be found for a computed destination address. Preferably backward symbolic execution is performed while constructing the flowgraph, in order to find the locations of additional instructions. As additional instructions are found, new blocks and new paths between blocks are added to the flowgraph. Backward symbolic execution is repeated when the new paths may provide additional values for the computed destination addresses.

Title: Echogenic devices, material and method
Inventor: BOSLEY RODNEY W JR
IPC: G01N29/24
Filed: 1993-01-20
Granted: 2003-12-02
Abstract: Echogenic medical devices and methods of fabrication and of use are disclosed. The devices are adapted to be inserted into a patient. The device includes an elongated member including a material having an acoustic impedance different from that of the surrounding medium. The medium includes surrounding biological tissue or fluids surrounding the member when inserted into a passageway of the patient.      The acoustic impedance of the elongated member is sufficiently different from the surrounding medium for enhancing an image produced in response to a sonic beam produced from imaging equipment. The elongated member also includes an interface layer of a high density metal of which the deposition on the base material of the member is ion beam assisted. The interface layer includes an outside surface having a plurality of particulate-type, discontinuous curved surfaces of partially spherical indentations formed therein or spheres extending therefrom.      The difference between the acoustic impedances of the interface layer and the surrounding medium along with the discontinuous surfaces of the interface layer cooperate in response to a beam from sonic imaging equipment to significantly enhance the image of the medical device member.

Abstract: A wire tensioning device having a guide for taking up an advancing wire having slack and a brake for applying a braking force to the guides. In a wire insulating system, a wire from a supply reel or spool is passed to a take-up reel or spool, through intervening components, which accumulate, tension and apply insulation to the advancing wire. The wire is first passed from the supply reel to an accumulating device in the form of a vertical accumulator or a flipper payout.      From there it is passed through the device of the present invention having a plurality of rotatable sheaves or pulleys about which the advancing wire is trained. A braking force is applied to one of the sheaves by an air brake to apply a tensioning force.      From the tensioning device, the wire is fed through an insulation-applying crosshead device and then on to a take-up reel or spool.

Abstract: A method of reducing the damaging effect of an injury to mammalian cells by treatment of the cell or mammalian tissue in vivo with a cell membrane permeant calcium buffer. The method comprises treating mammalian tissue with a damage reducing effective amount of the calcium buffer, preferably, a BAPTA derivative. The method may be used to control the concentration of Ca2+ ions in the vicinity of ion channel pores of the cells to prevent diffusion of toxic amounts of Ca2+ ions to subcellular sites located near the source of Ca2+ influx. The buffer treatment may be applied as a prophylactic or after the mammalian tissue has sustained injury. Pharmaceutical compositions comprising the calcium buffer and method of manufacture therefor are described.

Abstract: An apparatus and method for aiming a vehicle headlight to a standard image pattern includes a frame movable relative to the vehicle.  A housing carried on a vertically adjustable housing includes a lens focusing a headlight beam onto a reflective screen which reflects the beam image to a camera.  A control compares the digitized image output from the camera with a standard image pattern and generates a correlation factor based on the difference between the reflected image and a standard image.  Based on the difference, the control generates output signals to an adjustment device engagable with the headlight mounting frame to adjust the position of the mounting frame to reduce the difference to zero.
