摘要:
A diagnostic test kit for detecting the presence or quantity of an enzyme or enzyme inhibitor is provided. The diagnostic kit utilizes reactive complexes to facilitate the detection of the enzyme or enzyme inhibitor. The reactive complexes include a substrate joined (e.g., covalently bonded, physically adsorbed, etc.) to a reporter and magnetic substance. In one embodiment, for example, a peptide, protein, or glycoprotein substrate is joined to a reporter (e.g., dyed latex particle) and magnetic particle. In this embodiment, the substrate provides a cleavage target for a proteolytic enzyme. Specifically, upon contacting the reactive complexes, the proteolytic enzyme cleaves the substrate and releases the reporter and/or magnetic particle. The signal exhibited by the released reporters may then be used to indicate the presence or quantity of an enzyme or enzyme inhibitor within the test sample.

There is provided a lateral flow assay device for detecting the presence or quantity of an analyte residing in a test sample where the lateral flow assay device has a porous membrane in liquid communication with a conjugate pad and a wicking pad. The conjugate pad has a gold colloid-containing detection probe. The porous membrane has a detection zone where an immobilized first capture reagent configured to bind to at least a portion of the analyte and analyte-conjugate complexes to generate a detection signal. The control zone is located downstream from the detection zone on the porous membrane and has a second capture reagent immobilized within the control zone. The conjugate pad is located upstream from the detection zone, and has detection probes with specific binding members for the analyte. A sample containing an analyte is deposited on the conjugate pad, interacts with the detection probes, and moves toward the control zone for detection.

The invention provides inhibitors of chondrosarcoma cell growth that are useful as anti-cancer and anti-tumor agents. The inhibitors are peptides having sequences related to cleavage regions of the proenzyme forms of matrix metalloproteinases and that can inhibit the activity of matrix metalloproteinases. The peptide inhibitors of the invention can be formulated into therapeutic compositions, lotions, creams and wound dressings.

A vaginal treatment composition that rapidly forms a gel when placed into contact with monovalent or polyvalent cations, such as sodium (Na+) and calcium (Ca2+) cations naturally found in vaginal mucosa, is provided. The gel may form in less than about 1 hour, in some embodiments less than about 1 minute, and in some embodiments, less than about 30 seconds. Among other things, such rapid gelation reduces the likelihood of leakage during use. In addition, because the gel may form intravaginally, it is more likely to retain its structure and shape over an extended period of time. In this manner, the gel may provide the prolonged release of a therapeutic agent that inhibits and/or treats vaginal infection. For instance, the gel may remain within the vagina for about 2 to about 48 hours to provide the desired effect.

There is provided a new thermo-gelling composition made with methylcellulose and citric acid. This composition may also have an effective amount of a treating agent, which may be a medicinal agent, cosmetic agent, moisturizer, adjuvant, nutritional agent, other ingredients and combinations thereof. The composition is useful in delivering moisturizers or pharmaceutically active agents to the user in a controlled release manner through the mucosal tissues in a body cavity, or on body surfaces, or as a subcutaneously injected medicament. The composition may also be used as a replacement for the soft tissues of the body as in, for example, the foot cushion and cartilage repair.

摘要:
A biodegradable biodelivery device is disclosed. The biodelivery device is formed from a polymer comprising the reaction product of a polyol and a polyacid. When exposed to water, the polymer degrades through hydrolysis. Of particular advantage, the polymer can be formed so as to be elastic and flexible. In one embodiment, the polymer is formed into a vaginal insert. As the polymer degrades, the polymer releases acid to a vaginal environment for decreasing the pH of the environment.
