Abstract: [Problem] If lidocaine is composed of non-aqueous patch, the adhesive power of the preparation tends to get lower, as the composition amount of lidocaine is higher. It is popular to solve lidocaine in dissolving agent in order to compose lidocaine in patch and release effective amount into skin. However, if the amount of dissolving agent gets higher, the adhesive power gets extremely lower, so that an long-time attachment is difficult. [Solution] A non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent which are contained in a base of plaster, the plaster being hold by a support, of which strength of 50% stretched to longitudinal direction is less than 2,000 g/50 mm and of biaxially-oriented stretch cloth.

Abstract: A therapeutic composition comprising a purified fraction of adipose-derived mesenchymal stem cells encapsulated in a three-dimensional biocompatible gel matrix, and methods, and systems for preparing and using encapsulated adipose-derived mesenchymal stem cells. Hydrogel microbeads encapsulating stem cells maintain the viability and location of the stem cells for an extended period as compared to stem cells in suspension. The gel matrix allows the release of cellular factors from the encapsulated stem cells to surrounding tissues to achieve desired therapeutic results.
Abstract: A method of marking an inventory item includes providing an activatable smoke generator and a reservoir for holding a smoke fluid and adapted to provide a flow of smoke fluid to the generator. The reservoir contains a smoke fluid including a carrier nucleic acid having a uniquely identifiable sequence, and upon activation of the smoke generator, marker smoke is generated and targeted to flow over the inventory item. The method further includes activating the smoke generator to produce the marker smoke including the carrier nucleic acid so as to cause the marker smoke to flow over the inventory item and thereby to detectably mark the inventory item with carrier nucleic acid. The invention provides methods for stably binding and immobilizing deoxyribonucleic acid onto objects and substrates. The method includes exposing the deoxyribonucleic acid to alkaline conditions, and contacting the deoxyribonucleic acid to the object or substrate.

Abstract: A method for treating a defect site in a living bone of an animal by applying an exogenous compound having thrombopoietic activity to the defect site in an amount effective to induce thrombopoiesis. The exogenous compound activates a thrombopoietin receptor, leading to accelerated bone formation at the defect site. Also provided is a method for repairing a segmental bone defect in an animal bone by inserting into the segmental bone defect a biodegradable bone repair scaffold that contains a compound having thrombopoietic activity. The compound activates a thrombopoietin receptor and accelerates bone formation such that bridging occurs at the segmental bone defect.

Abstract: A method includes conveying a detection solution containing a target amplicon into a detection module of a molecular diagnostic test device. The detection module includes a detection surface including a series of capture probes to which a first portion of the target amplicon is bound when the detection solution is conveyed. A first reagent formulated to produce a visible signal indicating a presence of the target amplicon is then conveyed into the detection module. The first reagent is bound to a second portion of the target amplicon when the first reagent is conveyed. A second reagent is conveyed into the detection module. The second reagent includes a precipitating substrate formulated to catalyze the production of the visible signal by producing an insoluble colored product when the second reagent is in contact with the first reagent. The method includes viewing the visible signal via a transparent portion of the detection module.
