Abstract: The present invention relates to a blood cell proliferation assay employing Staphylococcus aureus antigen capable of inducing a proliferative response. The assay finds particular application in testing cattle, including cows and bulls for use in predicting resistance to subclinical or clinical mastitis.

Abstract: The active, galactose binding site of proteins associated with metastatic tumor cells has been identified and sequenced. The polypeptide comprising the active site may be used as an immunotherapeutic agent. Identification of the site makes possible an in vivo diagnostic assay for metastatic cell as well as therapeutic methodologies and materials.

Abstract: A self-test electronic assembly performs self-testing, such as diagnostic or run-in testing of components and circuits, based upon internally stored test procedures. The results of self-testing are stored internally to the device, providing valuable information regarding the self-test electronic assembly, both during the manufacturing process, and preferably for ongoing in-situ operation. A test system is preferably linked to one or more self-test electronic assemblies, and provides loopback circuitry for each installed self-test electronic assembly, whereby the self-test electronic assemblies can further test components, circuitry, and security encoding and decoding operation. The preferred test rack also provides efficient and consistent monitoring and quality control over the self-testing of self-test electronic assemblies.

Abstract: A pharmaceutical compound and a process for making the compound is provided where the compound includes a therapeutic agent, a spacer and a galactose, the spacer being covalently linked to the therapeutic agent at a first site on the spacer and covalently linked to the galactose by an ether bond at a second site on the spacer to form a conjugate. The conjugate may be used to treat a subject suffering from a medical condition, so as to reduce the side effects associated with the therapeutic agent by administering an effective dose of the conjugate to the subject so that the side effects in the subject are less then they would have been with the unconjugated therapeutic agent.

Abstract: A radioimaging material or a radioprotective material is attached to a carbohydrate which is capable of binding to or penetrating a cell. The carbohydrate material can be preferentially taken up by tumor cells and provides for imaging thereof.

Abstract: The present invention includes maintaining the region of the proximal lens of a laparoscope at greater than ambient temperature in order to prevent fogging during use. Heating is accomplished using commercially available chemical heat packs generally used for heating boots or gloves. The invention differs from other anti-fogging devices, which either immerse the distal lens region of the laparoscope in a warm fluid or treat this lens with anti-fogging solutions, in that above-ambient temperature is continuously maintained throughout the laparoscope, since it is known that a cool laparoscope fogs when placed in the vicinity of warm, wet tissue.

Abstract: Materials comprised of linked, repeat units of beta glucosamine, having a molecular weight in the range of 400 to 10,000 are highly effective in controlling fungus infestation in agricultural crops, both pre-harvest and post-harvest. The antifungal material is preferably combined with a mildly acidic solvent to produce a composition having a slightly acidic, or near neutral pH. When the antifungal material is combined with a chitosan matrix, a synergistic interaction occurs which greatly enhances the effect of the resultant composition. Also disclosed is a method for producing a chitin or chitosan based material which will dissolve in water having a neutral pH.

Abstract: An oligomer comprised of repeat units of beta glucosamine exhibits broad antifungal activity. The oligomer preferably has a molecular weight in the range of 4,000-18,000 dalton, and may be partially acetylated. These materials are highly effective against a variety of fungi including various species of Candida.

Abstract: An immunotherapeutic agent is prepared from cells of E. coli or members of the genus Mycobacterium. The material is effective as an anti-tumor agent, an immunostimulant, and an adjuvant. Also disclosed is a method of evoking an immunostimulatory response through the activation of the RAS gene.

Abstract: A lightweight, slender knife having a replaceable, retractable cutting blade, which may be locked either in the operating or deployed position, or in a retracted or safety position, by using a single digit on one hand, is described. Safety of hospital personnel and medical waste-disposal personnel is achieved in the surgical scalpel embodiment of the present knife without loss of function or convenience of the scalpel. An automatically retracting embodiment of the knife is also described.

Abstract: A three-piece knife having a replacable, retractable cutting blade, which may be locked either in the operating or deployed position, or in a retracted or safety position, by using a single digit on one hand, is described. Safety of hospital personnel and medical waste-disposal personnel is achieved in the surgical scalpel embodiment of the three-piece knife without loss of function or convenience of the scalpel.
