Title: Yolk sac stem cells and their uses
Inventor: WAGNER THOMAS E
IPC: A61K35/54
Filed: 1994-07-08
Abstract: The present invention is directed to mammalian yolk sac stem cells. In particular, it relates to the characterization, culturing, long-term expansion and uses of yolk sac stem cells for in vivo reconstitution and therapy. Yolk sac stem cells isolated from the early embryonic yolk sac prior to blood island formation exhibit a homogeneous morphology and a primitive cell surface phenotype without the expression of mature leukocyte markers and major histocompatibility complex-encoded antigens. The cells can be cultured and expanded long-term with minimal differentiation, and without alteration of their pluripotency. However, such cells can be induced to express various blood cell markers upon stimulation with specific cytolcines. Yolk sac stem cells may have a wide range of applications including but not limited to the reconstitution of a destroyed or deficient human hematopoietic system, and the construction of large and small animal models for the production of human blood cells, human antibodies, and testing of human diseases, immune function, vaccines, drugs and immunotherapy.

IPC: A23N4/14
Filed: 1994-03-22
Abstract: A pear processing method and apparatus is provided which includes several mechanisms for properly orienting the pear prior to coring, peeling and seed celling of the pear.  Each pear is  tumbled between a pair of orienting rolls to a position wherein the stem of the pear is oriented downwardly. Whiskers  on one of the rolls speed up this orienting of the pear.  A friction clutch on the other roll helps maintain the pear in its proper position, once the proper alignment  has been attained.  The pear is dropped downwardly into a transfer cup having four resilient fingers which tend to orient the pear.  The pear is then pushed out of the transfer  cup downwardly  into a feed cup having a concave receptacle  for centering the stem of the pear and three upwardly  extending arms which grasp and center the blossom end of the pear.  The pear is then transferred to a station wherein the  pear is cored and thereafter peeled and seed celled simultaneously. The stem and blossom are also trimmed.  The pear is  thereafter passed into a slice cup having a design which more effectively separates the waste from the processed pear.

Title: Hormonal agent for skin treatment
Inventor: GOLBS SIEGFRIED
IPC: A61K8/63
Filed: 1996-09-16
Abstract: The pharmaceutical composition, especially for treating skin with seborrhea, Acne vulgaris and androgonically conditioned alopecia, contains a hormonal agent including the gestogen, dienogest, or a combination of dienogest and an estrogen, as active ingredient. Methods for treatment of this type of skin condition include topical application of the composition including the dienogest which results in an outstanding sebosuppression, a drastic reduction of androstandiol glucuronide and a moderate competitive blockage of androgen receptor sites. Galenic formulations are described which limit and/or prevent the permeation of the active ingredient through the skin. The pharmaceutical preparation including the dienogest and conventional dermatologically acceptable carrier and auxiliary substances in the described galenic formulation advantageously provides a drastic reduction in androstandiol glucuronide and moderate androgen receptor blockage without passing through the skin barrier so that systemic effects including side reactions are substantially prevented.
Patent CA-2188774-A1 (CA)
Title: Fiber optic radiation transmission system, connector system for an optical fiber, and methods of using same
Inventor: EVANS WILLIAM JAMES
IPC: G02B6/42
Filed: 1996-10-28
Abstract: A fiber optic radiation transmission system is provided in which an optical fiber and a radiation source are connected to establish optical communication therebetween. Additionally, a connecting system is provided for connecting an optical fiber and a radiation source such that optical communication is established therebetween. The systems include a connector which carries the optical fiber therein. The connector is extendable within the system toward the radiation source to bring the optical fiber into optical communication with the radiation source. More particularly, the systems are configured in such a way that when the connector is extended sufficiently within the system, it seats the optical fiber relative to the radiation source under bias, thereby establishing a reliable optical connection. Once the optical connection is thus established, the connector engages a connection port associated with the radiation source to secure the system in a fully connected configuration appropriate for use. Thus, in a method of using such a system, the user simply extends the connector until the connector engages the connection port. The present invention thus provides efficient and reliable systems in which optical communication is established between an optical fiber and a radiation source.

A query is formatted at the remote unit, the query including the request, and is transmitted from the remote unit to the base unit. Requested route guidance information is calculated at the base unit in response to the query, using a large up-to-date database located at the base unit. A response to the query is formatted at the base unit, the response including route guidance information. The response is then transmitted from the base unit to the remote unit for display. The transmission is made in a compact form through the use of maneuver arms and combined maneuver arms and through the use of tokenized forms. A maneuver arm represents a road at an intersection, for depiction on a display, by one or two endpoint coordinates. The tokenized forms are expanded at the remote unit into textual driving instructions for each of one or more languages. In addition, the amount of information available at a remote unit can be increased by providing the remote unit with information from the base unit which is not adequately covered by any databases on-board the remote unit.

Title: Multi-stage collagen-based template or implant for use in the repair of cartilage lesions
Inventor: PACHENCE JAMES M
IPC: A61B17/06
Filed: 1996-02-08
Abstract: The invention is a template (12) to aid in the regeneration of articular cartilage. The template (12) is formed by combining a porous collagen sponge ("collagen matrix") (13) with a dense collagen membrane (14). The dense collagen membrane (14) is placed on the surface of the cartilage defect to prevent cell migration from the subchondral plate (9) and vasculature. The collagen membrane (14) will allow movement and exchange of fluids, nutrients, cytokines and other factors necessary for cartilage regeneration. The collagen matrix (13) has been developed to allow attachment and growth of cells, specifically chondrocytes (6) which are normally found in articular cartilage.  The collagen matrix (13) can be combined with chondrocytes in vitro, and therefore serve to transport cultured cells to the defect site and to retain the cells in position following implantation. Procedures are described to effectively use the two-stages template (12), and to fix the template to the repair site.
