Patent CA-2115651-A1 (CA)
Title: Medicament coated refractive anterior chamber ocular implant
Inventor: GALIN MILES A
IPC: A61F2/14
Filed: 1992-08-13
Abstract: A minus power anterior chamber ocular implant for placement in the anterior chamber of a phakic eye having an anatomic lens in situ comprises a negative artificial refracting lens having at least one concave surface, a surface coating which comprises a compatible sulfated polysaccharide medicament coating, such as heparin, and means for positioning the artificial lens in the an-terior chamber of the eye to prevent contact between the implant and the anatomic lens. The implant compensates for refractive errors or creates a specific refraction to assist in visual function and has increased biocompatibility in the anterior chamber of the eye, thereby preventing or mitigating detrimental effects typically associated with the implantation of an uncoated refractive ante-rior chamber implant in the eye. A method of preparing such a minus power anterior chamber ocular implant comprises first ex-posing an uncoated implant to a plasma to generate a plasma-treated implant having a surface containing amines, carboxylic ac-ids, active free radicals or passive free radicals; and thereafter bonding the medicament to the plasma-treated implant surface. A method of treating myopia comprises surgically implanting and anchoring the implant in the phakic eye to compensate for refrac-tive errors.

Filed: 1994-05-04
Abstract: An intake manifold for an internal combustion engine includes a rigid intake pipe having a flow-through passage, and an adjustment structure for adjusting the size of the flow-through passage. The adjustment structure is a check valve which opens only in direction of the internal combustion engine and includes a valve body and a valve seat which are movable relative to each other and are selectively interengageable for the closing of the flow-through passage. The check valve prevents a backflow of gases from the internal combustion engine into the intake manifold thereby increasing the engine's power output especially at low engine speeds.

Title: New cultures of keratinocytes, process for their preparation and their use as wound healing substances
Inventor: VAN BOSSUYT HANS
IPC: A61K35/36
Filed: 1992-11-19
Abstract: Cultures of keratinocyte cells are provided which are free from nonautologous fibroblasts and organ extracts, and which have a high speed of cell amplification for a minimum seeding density. Preferably, a culture contains no more than about 10% autologous non-keratinocyte cells such as star--shaped, non-keratinocyte cells and no more than about 1%  autologous fibroblasts. The cultures can be cryopreserved in a buffered isotonic medium containing serum and a cryoprotectant.  The cultures are produced by a process that does not involve the use of a feeder layer and organ extracts. A culture medium used contains Medium 199, serum, epidermal growth factor, cholera toxin and/or hydrocortisone, and optionally insulin. A  substance for wound healing and for cosmetic applications is derived from cultured human keratinocytes. Lyophilized keratinocyte cell cultures or an extract therefrom is used to provide a pharmaceutical composition. Confluent and cohesive keratinocyte sheets are prepared for use in wound healing. A  non-viable total keratinocyte lysate for use in promoting wound healing is produced by growing keratinocyte cells on a support, detaching the cells from the support, and lysing the detached cells to obtain the lysate. The lysate may be frozen and lyophilized. The detached cells may be frozen to produce the lysate without lysis before freezing.

Title: Selectable/Reporter Gene for Use During Genetic Engineering of Plants and Plant Cells
Inventor: PELCHER LAWRENCE E
IPC: C12N9/78
Filed: 1994-10-25
Abstract: Adenosine deaminase gene (ADA gene) is used as a selectable/reporter gene for plant cells and plants.  When introduced into plant cells, the ADA gene makes the cells resistant to inhibition by 2-deoxyadenosine or an analog, so transformed cells can be separated from non-transformed cells by culturing a cell mixture in a medium containing 2-deoxyadenosine or an analog in amounts that inhibit normal plant cells.  A single vector may be constructed containing an ADA gene from any source (e.g. a mouse ADA gene) and an additional gene-of-interest to be introduced into plant cells. The vector may then be introduced into the cells by such a route as Agrobacterium infection or micro projectile bombardment.  The presence of the ADA gene in successfully transformed plant cells may be confirmed by cultivating the cells in a medium containing 2-deoxyadenosine or an analog in the presence of a material that changes color in the presence of ammonia. Observation of a color change confirms the presence of the gene.  DNA constructs containing both ADA genes and foreign genes-of-interest may be constructed, e.g. plasmid pRD360-ADA (ATCC 69459).

The mouse having been administered a combination of the antibody of the present invention and an anti-SCF receptor antibody has concentrated hematopoietic stem cells.          Therefore, the use of the bone marrow cells or spleen cells of such a mouse makes it possible to evaluate a hematopoietic stem cell growth factor.  Therefore, the method of evaluation according to the present invention is useful for searching for a hematopoietic stem cell growth factor.

Abstract: A device interconnects within the phone line coming from a first phone and routes telephone calls along a least cost route originating from the first telephone to a second telephone via the network.  A housing forms an enclosure and has a first jack for interconnection to the phone side of the phone line and a second jack for interconnection to the network side of the phone line.  The housing forms an enclosure which includes therein a switch for disconnecting the first phone from the network.  The device generates a source of current through the switch to the first phone corresponding to the amount of current provided by the phone network.  A database stores billing rate parameters for determining various communication paths of different carriers based on parameters such as the time and date of the call.  Phone calls from the first phone are detected and stored.  The database is addressed and a plurality of communication switch paths are identified as well as the cost rate of each path.  The cost rates for each identified path are compared to determine a least cost route for the call.   The device generates a number sequence corresponding to a desired carrier so that the dialed call is routed through the second jack and phone line to the selected communication path and carrier so as to establish a switched connection between the first and second phones.

Title: A roll, having controlled bending, for a calender or similar device
Inventor: VAN HAAG ROLF
IPC: F16C13/00
Filed: 1995-07-21
Abstract: A roll whose bend can be controlled has support elements which are designed as ring elements with an annular pocket and an annular pressure surface. The interior space enclosed by the ring element is connected to an outlet line having an adjustable throttle element. By appropriately adjusting the throttle element, any arbitrary intermediate pressure can be maintained in the interior space.
