Abstract: A biocompatible and biodegradable barrier material is applied to a tissue region, e.g., to seal a vascular puncture site. The barrier material comprises a compound, which is chemically cross-linked without use of an enzyme to form a non-liquid mechanical matrix. The compound preferably includes a protein comprising recombinant or natural serum albumin, which is mixed with a polymer that comprises poly(ethylene) glycol (PEG), and, most preferably, a multi-armed PEG polymer.

Abstract: A device for sample collection, sample separation and for aseptically, controllably and precisely transferring at least one of the separated portions is disclosed. The device utilizes a metering syringe to collect a sample, such as blood, the metering syringe with the sample therein is centrifuged, the metering syringe is connected to a sterile syringe contained within sterile packaging, the metering syringe is used to controllably, precisely and aseptically meter a separated portion into the sterile syringe, the sterile syringe with the separated portion therein is then given to appropriate personnel within a sterile field without performing any further transferring steps.

Abstract: Pavement markings of improved durability are obtained by first forming a bonding layer on the pavement surface with a liquid coating composition that comprises a polyamide condensation product of dimerized fatty acid and polyamine and then forming a top or marking layer over the bonding layer by applying through a flame solid particles of a marking material that comprises the same type of polyamide, preferably in a higher-molecular-weight version.
