The present invention relates to oral composition and the method of preparation and use of such composition for inhibiting, reducing, and/or disrupting oral biofilm. The composition comprises a stabilizing matrix, a cationic biocide, and a peroxide source.

The present invention relates to a formulation or composition for the treatment, repair, formation or regeneration of bone tissue in a subject, comprising Histatin-1 or its derivatives. The present invention also relates to a biomaterial comprising Histatin-1 or its derivatives in a biocompatible material, and a method for the treatment, repair, formation or regeneration of bone tissues in a subject comprising administering to the subject a therapeutically effective amount of Histatin-1 or its derivatives.

The present application provides that synthetic retinoid compounds are useful in methods of treating bacterial infections, such as a bacterial infection caused by S. aureus, methicillin-resistant S. aureus (MRSA), vancomycin-resistant S. aureus (VRSA), E. faecalis, E. faecium, B. subtilis, and B. anthracis. The present application also provides a tricyclic fluoroquinolone compound, Z3060, useful in methods of treating bacterial infections, such as a bacterial infection caused by S. aureus, methicillin-resistant S. aureus (MRSA), vancomycin-resistant S. aureus (VRSA), E. spp., K. pneumoniae, P. aeruginosa, A. baumannii, E. faecium, and E. faecalis. Also provided herein is a gold compound, auranofin, useful in treating bacterial and fungal infections, such as a fungal infection caused by C. albicans, C. parapsilosis, C. tropicalis, C. glabrata, and C. neoformans.

A synthetic peptide including the sequence SHXGY (SEQ ID NO:2) is described as are methods of using the same for promoting wound healing and epithelial cell migration.

Described herein are protein-payload conjugates and compositions thereof that are useful, for example, for target-specific delivery of therapeutic and/or imaging agent moieties. In certain embodiments, provided are specific and efficient methods for producing protein-payload constructs (e.g., antibody-drug conjugates) utilizing a combination of transglutaminase and Diels-Alder techniques. Antibody-drug conjugates and compositions which comprise glutaminyl-modified antibodies, Diels-Alder adducts, and reactive payloads and are provided.

Described herein are electrospun core-shell fibers that include (i) a central core that is electrically conductive having an exterior surface, wherein the core comprises a first polymer and an electroconductive material; (ii) a shell adjacent to the exterior surface of the core, the shell comprising a second polymer; and (iii) one or more bioactive agents in the shell. In one aspect, the fibers are electrospun fibers. Additionally, described herein are methods for making and using the core-shell fibers.

Synthetic antimicrobial peptides, compositions comprising thereof, and methods of use for modulating one or more symptoms of an infection in a subject are disclosed. In some aspects, the infection is caused by mycobacteria, for example, a nontuberculous mycobacterium such as Mycobacterium abscessus. In other aspects, the infection is caused by Escherichia coli, Pseudomonas aeruginosa, or methicillin-resistant Staphylococcus aureus (MRSA). Also disclosed are methods of identifying synthetic antimicrobial peptides against a pathogen with no known effective treatment using a library of synthetic peptides.

Embodiments of the disclosure concern methods and compositions of treating or preventing viral infection, including of SARS-CoV-2, for example. In specific embodiments, one or more adjuvants are delivered to an individual receiving and/or having received fibroblasts and/or fibroblast-derived exosomes. In specific cases, the adjuvants comprise particular peptides, chloroquine and/or hydroxychloroquine, and/or one or more activators of one or more toll like receptors.
