Glucocorticoid-induced leucine zipper protein (GILZ) peptide compositions and their methods of use in wound healing are disclosed herein. An exemplary GILZ peptide composition includes a GILZ fusion protein. The GILZ peptide compositions can be administered topically to wounds, for example in the form of a cream, ointment, or lotion. The GILZ peptide compositions can be used to treat acute wounds, induce wound healing in chronic wounds, and reduce scar formation.

The present invention relates to peptides capable of forming a gel and to their use in tissue engineering and bioprinting. The present invention furthermore relates to a gel comprising a peptide in accordance with the present invention, to a method of preparing such gel and to the use of such gel. In one embodiment, such gel is a hydrogel. The present invention furthermore relates to a wound dressing or wound healing agent comprising a gel according to the present invention and to a surgical implant or stent comprising a peptide scaffold formed by a gel according to the present invention. Moreover, the present invention also relates to a pharmaceutical and/or cosmetic composition, to a biomedical device or an electronic device comprising the peptide according to the present invention.

The present disclosure provides biocompatible and bioresorbable devices for tissue repair and regeneration and delivery of an active agent across a biological barrier comprising silk fibroin and hyaluronic acid.

Meshes for use to control the movement of bodily fluids, such as blood, are described herein. The mesh can be partially or completely biodegradable or non-biodegradable. In one embodiment, the mesh is formed from one or more self-assembling peptides. The peptides can be in the form of fibers, such as nanofibers. The peptides can be assembled prior to formation of the mesh or after the mesh has been formed but before it is applied. Alternatively, the mesh can be prepared from unassembled peptides, which assemble at the time of application. The peptides can assemble upon contact with bodily fluids (e.g., blood) or can be contacted with an ionic solution to initiate assembly.

The present disclosure relates to ultrashort peptides capable of forming a gel, to a gel comprising a peptide in accordance with the present disclosure, and to a method of preparing such gel. Such gel is a hydrogel or an organogel. The peptides are suitable bioinks for a bioprinter to build 3D structures through 3D printing as well as other applications.

[Problem to be Solved] It is intended to provide a composition for hemostasis which can be uniformly applied to a bleeding site and exerts a high hemostatic effect.

[Solution] The present invention provides a composition to be applied as a spray to a subject, the spray being used for hemostasis, and the composition comprising a self-assembling peptide, wherein the self-assembling peptide self-assembles and thereby gels when the composition is applied to a bleeding site of the subject, and the self-assembling peptide is contained in the composition at a concentration at which the composition has an improved hemostatic ability as compared with that when directly applied.

A method of crosslinking a protein or peptide for use as a biomaterial, the method comprising the step of irradiating a photoactivatable metal-ligand complex and an electron acceptor in the presence of the protein or peptide, thereby initiating a cross-linking reaction to form a 3-dimensional matrix of the biomaterial.

Provided are pharmaceutical foam compositions comprising a peptone, a peptide hydrolysate or an enzymatically-hydrolyzed protein prepared by enzymatic hydrolysis of a full-length protein; methods of preparation and uses thereof.

An improved surgical device is disclosed herein. The improved surgical device includes a delivery device and a sealed container. The sealed contained is prepositioned internal to the delivery device and includes an antimicrobial solution. The improved surgical device is configured for inserting an implant into a surgical site. In some embodiments, the sealed container is configured to be manually broken to release the antimicrobial solution prior to inserting the implant into the delivery device. In other embodiments, the sealed container is configured to be automatically broken to release the antimicrobial solution prior to inserting the implant into the delivery device.

The present invention relates to a functional 3D neuronal model based on ultrashort self-assembling peptide scaffolds in accordance with the present invention, and to a method of preparing such a model. The models are suitable for in vitro drug testing, cellular replacement therapies as well as other applications.
