Abstract: Oral cavity wound healing occurs in an environment that sustains ongoing physical trauma and is rich in bacteria. Patients undergoing cleft palate repair have a high degree of wound healing complications, such as oronasal fistula (ONF) formation. Following hard palate injury, ONF was created that demonstrated little change in pro-regenerative monocytes LY6Clo monocytes; however, there were increased M2 macrophages observed. Delivery of FTY720 nanofiber scaffolds following hard palate injury prevented ONF formation, allowed complete wound healing and was associated with increased LY6Clo monocytes and pro-regenerative M2 macrophages. Evaluation of interleukin gene expression revealed reduction in pro-inflammatory IL1 and IL6 and increased expression of pro-regenerative IL10 with FTY720 nanofiber delivery.

Abstract: Amorphous SiOx (SiO2), SiONx, silicon nitride (Si3N4), surface treatments are provided, on both metal (titanium) and non-metal surfaces. Amorphous silicon-film surface treatments are shown to enhance osteoblast and osteoblast progenitor cell bioactivity, including biomineral formation and osteogenic gene panel expression, as well as enhanced surface hydroxyapatite (HA) formation. A mineralized tissue interface is provided using the amorphous silicon-based surface treatments in the presence of osteoblasts, and provides improved bone cell generation/repair and improved interface for secure attachment/bonding to bone. Methods for providing PEVCD-based silicon overlays onto surfaces are provided. Methods of increasing antioxidant enzyme (e.g., superoxide dismutase) expression at a treated surface for enhanced healing are also provided.

Abstract: Covalently cross-linked copolymers are described herein. More specifically, polysaccharide-polyamine copolymeric matrices or structures and cationic copolymeric matrices are described herein. The polysaccharide-polyamine copolymers, when protonated, can form cationic copolymeric matrices having exceptionally high densities of cationic sites. In one form, the covalently cross-linked copolymers provide a three-dimensional structure, especially when hydrated.

Abstract: A composition that can solvate biofilms and disrupt bacterial cell walls acts to both kill the bacteria by cell lysis and remove the biofilm. This solvent-containing composition is effective against a broad spectrum of microbes and can be used on a variety of surfaces, both living and inanimate. The polarity of the solvent component of the composition is lower than that of pure water so that the composition exhibits increased efficacy in solvating the macromolecular matrix of a biofilm and in penetrating bacterial cell walls.

Abstract: A pharmaceutical composition comprises a taxane (e.g., paclitaxel, docetaxel, cabazitaxel, larotaxel, ortataxel, and/or tesetaxel) in a mixture of first and second surfactants. The absorption of the taxane is increased from the pharmaceutical composition is greater than the sum of the absorption of docetaxel from either the first or the second surfactant. The increase in absorption is especially enhanced when the ratio of the first surfactant to the second surfactant in the pharmaceutical composition is between 60:40 and 85:15 by weight, and the total surfactant weight does not exceed 98% of the total weight. Polysorbate 80, polysorbate 20, and caprylocaproyl polyoxylglycerides serve as suitable first surfactants, and polysorbate 80 or polyethyoxylated castor oil serve as suitable second surfactants. The stability of the pharmaceutical composition may be enhanced by further including a stabilizer (e.g., citric acid and/or ascorbic acid).

The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the severed end. The media may be a hydrogel, and the transformation may produce a synthetic crosslinked hydrogel protective barrier.
