Abstract: A lateral flow test strip for the analysis of a sample featuring numerous capture zones arranged in an array such that each capture zone is substantially equidistant from the sample containing area. The sample does not pass through another capture zone to reach any one of the other capture zones. The capture zones are preferably arranged in a linear array perpendicular to the flow of the sample through the lateral flow test strip. The lateral flow test strip allows for an increased number of simultaneous analyses of numerous analytes from one sample to occur on one lateral flow test strip.

Abstract: The invention relates to a method, a cryosurgical probe, and a cryosurgical instrument for freezing a lesion on biological tissue. The method involves repeated cycles of freezing and thawing of the tissue to ensure maximum treatment effectiveness. The cryosurgical probe may be positioned on an end of a cryosurgical instrument, and facilitates the freezing of a lesion on biological tissue via the evaporation of a refrigerant. The cryosurgical probe includes a receiving end, a hollow portion, and a tissue contact end. The receiving end is adapted to receive the refrigerant. The tissue contact end includes an orifice adapted to expose the lesion to the refrigerant, and preferably includes a guard portion adapted to prevent excessive exposure of the biological tissue surrounding the lesion to the refrigerant. The hollow portion allows the flow of refrigerant from the receiving end to the tissue contact end, and includes at least one exhaust port.

Abstract: A composition and method is provided capable of removing contaminants from the surface of a gelatin capsule, such as a paint ball, to allow the gelatin capsules to be used for their intended use. The composition comprising, by weight, about 70 to 99.9 percent of a water-soluble alcohol, about 0.1 to 30 percent water, about 0.1 to 10 percent of a volatile silicone, and about 0.1 to 1 percent of a non-volatile silicone. Furthermore, the composition prevents excessive swelling of the gelatin outer shell of the gelatin encapsulated product. A method is also provided for cleaning a gelatin encapsulated product comprising the steps of contacting the gelatin encapsulated product with a cleaning composition, separating the gelatin encapsulated product from the cleaner, and drying the gelatin encapsulated product. The gelatin capsule may be a paintball. The composition may include additives to improve the performance of the gelatin capsules.
