Abstract: Endoscopic surgery targeted at the sinuses and nasal turbinates assists in managing the symptoms of chronic rhinosinusitis and other conditions. With contemporary techniques, post-operative hemorrhage, synechiae formation and poor wound healing are amongst the most common complications. The present disclosure provides the use of self-assembling peptide matrix, PuraSinus, and significantly reduces the incidence of these post-operative complications, including prevention of synechiae formation and aiding hemostasis.

Abstract: Methods and materials for mitigating biological tissue adhesion are described herein. One method for mitigating adhesion to a biological tissue includes administering an effective amount of a self-assembling peptide solution to the biological tissue, wherein the self-assembling peptide is between about 7 amino acids and 32 amino acids in length and the self-assembling peptide solution forms a hydrogel under physiological conditions.

Abstract: A plurality of amphiphilic peptide chains having alternating hydrophilic and hydrophobic amino acids, wherein the peptide contains at least 8 amino acids, are complementary and structurally compatible, and self-assemble into a beta-sheet macroscopic scaffold wherein peptide at least about 75% of the chains have the same sequence.

Abstract: The present invention relates to a functional screen assay for nonsense or frameshift mutations that allows genes of interest to be scanned. This assay is based on the cloning of segments of the gene of interest in-frame with a sequence coding for a marker followed by screening for the level of expression of the marker. Individuals at risk for any one of a number of genetic diseases, which are associated with such nonsense or frameshift mutations, can be quickly screened for chain-terminating mutations introduced by these nonsense and frameshift mutations. At present, scanning of many genes for mutations requires significant effort because the genes are large and most mutations are unique. Therefore, this assay offers a powerful option for the diagnosis of many genetic diseases.
