The present disclosure provides viral microparticles comprising genetically-engineered baculoviruses (at least partially) embedded in a polymeric matrix for the local delivery of therapeutic nucleic acid molecules to the cells of a vertebrate individual (optionally in combination with a medical implant such as vascular stent platform). The viral microparticles are especially useful for promoting the healing of a wound as well as the repair of a blood vessel and prevent pathological scarring. Also provided herein are processes for making the viral microparticles, pharmaceutical compositions comprising viral microparticles as well as supports comprising the viral microparticles for the locating the viral microparticles in a wound or in the vicinity of a wound.

The present invention is directed to hemostatic compositions comprising at least partially integrated agglomerated ORC fibers, fibrinogen, and thrombin and methods of forming a powdered hemostatic composition, comprising the steps of: forming a suspension of a mixture comprising particles of fibrinogen, thrombin, ORC fibers in a non-aqueous low boiling solvent, agitating and shearing said suspension in a high shear mixing reactor, adding water to allow particles to agglomerate, allowing the non-aqueous solvent to evaporate, drying and sieving the composition; and thus forming the powdered hemostatic composition.

The two devices described allow for greater control over application of a fibrin biopolymer and yet remain simple enough to be used by both medical personnel and by non-medical workers. One of the devices includes chambers where components necessary for formation of a fibrin biopolymer are stored and are pushed by plungers connected to an actuator upon the actuator receiving pressure from the user, with the components mixing in a chamber within the device and flowing out of a tube connected to the mixing chamber before formation of the fibrin biopolymer is completed. The other device dispenses formulations that include components necessary for formations of a fibrin biopolymer onto a skin of a patient using one or more propellants, with the formation of the fibrin biopolymer being initiated after the formulations are dispensed on the patient's skin and are intentionally mixed together.

The present invention is directed to compounds, methods for stabilizing thrombin activity with a thrombin binding oligonucleotide and to stabilized thrombin. The thrombin binding oligonucleotide is capable of inhibiting thrombin activity whereby the inhibition can be reversed with an antisense oligonucleotide.

The present invention is directed to hemostatic compositions comprising at least partially integrated agglomerated ORC fibers, fibrinogen, and thrombin and methods of forming a powdered hemostatic composition, comprising the steps of: forming a suspension of a mixture comprising particles of fibrinogen, thrombin, ORC fibers in a non-aqueous low boiling solvent; spraying the suspension through a nozzle onto a substrate, allowing the non-aqueous solvent to evaporate; separating from the substrate and sieving the composition.

Methods of treating, reducing the risk of, preventing, or alleviating a symptom of inflammation or inflammatory disease, including wounds, diabetic ulcer, and inflammatory bowel disease, by administration of gel-based delivery particles, such as zwitterionic copolymer cryogels or chitosan microgels, containing cerium oxide nanoparticles.

Methods and compositions for treating retinoblastoma are disclosed. The methods comprise administering a composition comprising two or more chemotherapeutic agents and a fibrin sealant material to a patient in need thereof. The compositions comprise two or more chemotherapeutic agents and a fibrin sealant material. Also disclosed are dual-compartment syringes comprising two or more chemotherapeutic agents, fibrinogen, and thrombin.
