摘要:
Surgically implantable tissue engineered intervertebral disc tissues that effectively replicate the physicochemical properties of the corresponding in vivo tissues are provided. Methods for producing such tissues can involve culturing the intervertebral disc cells to produce cells surrounded by an extracellular matrix and culturing the cells and matrix on a semipermeable membrane to form a cohesive tissue.

A method for the reduction in the risk of transmitting a sexually transmitted disease--especially HIV and/or HSV--during sexual activity is provided. This method generally comprises the application of an effective amount of an inhibitory agent, preferably as a topical formulation, to the area or areas of sexual contact prior to engaging in sexual activity. Inhibitory agents which are useful in the present invention include, for example, phosphorylated hesperidins, sulfonated hesperidins, polystyrene sulfonates, substituted benzenesulfonic acid formaldehyde co-polymers, H.sub.2 SO.sub.4 -modified mandelic acids, and the like. This method can be used by heterosexuals, homosexuals, and/or bisexuals engaged in a wide variety of sexual activities. In addition to anti-STD activity, these agents may also act as vaginal contraceptives; moreover, they generally have fewer side effects than conventional vaginal contraceptives (e.g., nonoxynol-9). For example, the compounds useful in this invention are generally not toxic to natural and beneficial vaginal flora and, thus, do not upset the local microbiological balance. The anti-STD method of the present invention has the added advantage that it can be implemented and controlled by either sexual party. Methods are also provided for reducing the risk of transmission of STD-causing organisms to health care providers and laboratory personnel (or other persons) who may come into contact with biological samples and specimens.
摘要:
A femoral insert for a hip joint prosthesis wherein the proximal and distal portions are angularly joined to define a lateral apex, the apical height of which has a particular ratio to the medial length of the insert.
摘要:
A method for preparing blood samples containing red blood cells for automated analysis wherein the blood sample on a slide is spun to create a monolayer of randomly distributed red blood cells. To inhibit cell morphology distortions from occurring during drying, the morphologies of the cells contained in the monolayer are preserved by a fixing agent after monolayer preparation but prior to drying when such distortions would otherwise develop. The method and apparatus are particularly useful for fixing red blood cells to prevent loss of or deformation of a central pallor which would be detrimental to a subsequent automated analysis.
摘要:
A method for treating and preventing various infections, including papilloma virus and fungal and parasitic infections is provided. In particular, an effective amount of a sulfated polysaccharide, such as cellulose sulfate and dextran sulfate are administered to prevent and treat these infections. The invention also relates to use of these compounds for the prevention and inhibition of malignant epithelial lesions associated with papilloma virus, such as cervical cancer.
摘要:
A method for facilitating a performance review process. The method comprises receiving a list of reviewers and their relationship to a reviewee, generating an evaluation form for each reviewer based on the relationship between the reviewer and the reviewee, providing each reviewer with access to the evaluation form for completion, processing the completed evaluation form, and providing an evaluation results report.

摘要:
Method and apparatus for placing therapeutic devices such as embolic coils includes a probe assembly carried within a catheter. The probe assembly includes a fiber-optic cable with a connector retained thereon by crimping. The connector has a cable-receiving end resembling a ferrule, which is crimped about the cable. The other end of the connector provides mounting of a therapeutic device, such as an embolic coil. Heat releasable adhesive bonds the therapeutic device to the mounting portion of the connector. Laser energy transmitted through the fiber-optic cable is converted to heat by the connector, which thereupon becomes heated, releasing the adhesive bond between the connector and the therapeutic device. The probe assembly can then be withdrawn from the treatment site.
摘要:
A method for regulating bone resorption wherein the bone is exposed to an effective amount of a composition of matter obtained from avascular or poorly vascularized tissue by extracting the tissue with an aqueous extraction medium which includes a solute which does not irreversibly denature the proteinaceous matter to be extracted and recovering from the aqeuous extract substances having molecular weight below about 50,000.
摘要:
A method and apparatus is disclosed for use in performing automated classification of cells of a pap smear as well as other types of cells, such as red blood cells and blood cell neutrophiles. The apparatus generates an image that is split into two paths, (1) a high resolution image of primarily the nucleus of a cell, and (2) a low resolution image of the total cell, nucleus and cytoplasm. An image scanning device located in the first path provides output signals representing the image and circuitry performs measurement and analysis relating to texture of the nucleus. The image in the other path is demagnified which provides an enlarged, lower resolution image of the entire cell, including the nucleus and the cytoplasm and it is projected to a second image scanning device, which provides electrical signals that represent the image of the larger area and circuitry performs measurement and analysis relating to the size, density and color of the cytoplasm and the nucleus. The analysis obtained from each of the two circuits are applied to classification logic circuitry for the purpose of determining malignant cells.
