A barrier layer and corresponding method of making provide anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a medical device implantable in a patient. The barrier layer can be combined with a medical device structure to provide anti-adhesion characteristics, in addition to improved healing, non-inflammatory, and anti-inflammatory response. The barrier layer is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent.

Compositions for coating microneedles with aluminum-adjuvanted vaccines are provided comprising an aluminum-containing wet gel suspension selected from aluminum hydroxide wet gel suspension and aluminum phosphate wet gel suspension; a vaccine in an amount effective to stimulate an immune response in a mammal; a sugar, sugar alcohol, or combinations thereof; and a thickener. Some embodiments of the compositions have a viscosity of 500 to 30,000 cps when measured at 100 s.sup.−1 and temperature of 25 C. Microneedle devices coated with the compositions, as well as methods of forming the compositions and coating the microneedles, and methods of maximizing the aluminum content of vaccine-coated microneedle arrays are also provided.

Methods of forming, dissolving, and functionalizing an extracellular matrix gel on demand based on cross-linking, modification, and dissolution of hydrogels using transpeptidase (e.g. sortase) are disclosed. Also provided are hydrogels comprising one or more macromers crosslinked to a mixture of peptides, wherein all or a portion of the peptides in the mixture comprise a recognition motif cleavable by a transpeptidase (e.g., sortase).

A formulation of a pathogen inhibitor or probiotic as a slurry concentrate of a hydrated metal oxide for applications in agriculture, aquaculture, and as an anti antibiotic in which the bioactivity, when applied by dilution, is controlled by a precursor of Reactive Oxygen Species, and the release rate is controlled by the particle size. The invention may include a means whereby the precursor concentration may be controlled to meet the requirements of the ecosystem, from the maintenance of an aerobic system, to killing pathogenic, anaerobic microbes, or producing sterile ecosystems. In addition, the metal oxide may be selected to provide essential nutrients for growth of the agricultural or aquacultural products.

The invention relates to medicine, namely, to the solutions used for hemostasis. The hemostatic agent, which represents a polyammonia methanediamine chloride of the general formula

##STR00001##

where: n=1-20, m=1-10, at that n×m≧8.

The hemostatic agent may be applied in the form of a 0.01-10% aqueous solution. An aqueous solution of the preparation can be used for impregnation of materials used for bleeding arrest, suture material, bandaging material. The hemostatic agent may be used in the composition of a retraction cord, adhesive pastes, vaginal and rectal suppositories, creams, gels, as well as used with microchips that provide slow release of the preparation. The preparation can also be used in eye drops, eye ointments, and lubricants applied to the surface of the catheter. The drug can be used in endodontic treatment, may be injected into a polymer sealer for root canal obturation, as well as locally—by means of electrophoresis. The hemostatic agent may be used in conjunction with a gel based on aluminum sulphate or silver solution, and also with a polysaccharide haemostatic system. An efficient haemostatic preparation ensuring a significant analgetic effect is developed.
