Abstract:
Implant-associated bacterial infections are one of the most serious complications in orthopedic surgery. Treatment of these infections often requires multiple operations, device removal, long-term systemic antibiotics, and extended rehabilitation, and is frequently ineffective, leading to worse clinical outcomes and increased financial costs. Silver nanoparticle/poly(DL-lactic-co-glycolic acid) (PLGA)-coated stainless steel alloy (SNPSA) was evaluated as a potential antimicrobial implant material. It was found that SNPSA exhibited strong antibacterial activity in vitro and ex vivo, and promoted MC3T3-E1 pre-osteoblasts proliferation and maturation in vitro. Furthermore, SNPSA implants induced osteogenesis while suppressing bacterial survival in contaminated rat femoral canals. The results indicate that SNPSA has simultaneous antimicrobial and osteoinductive properties that make it a promising therapeutic material in orthopedic surgery.

Abstract:
Provided herein is a method of promoting tissue repair, comprising delivering to a subject a therapeutically effective amount of fibromodulin (FMOD), FMOD polypeptide, FMOD peptide, or a variant or derivative or analog thereof according to a dosing regimen to cause an injured tissue to form a repaired tissue having an improved condition provided that the improved condition does not include improved condition of scar of skin.
Abstract:
The application discloses an implantable device, comprising a galvanic redox system formed on a body substrate of the implantable device. The implantable device has a non-zero surface potential when it is deployed. The galvanic redox system comprises a first metal site and a second metal site, the first metal site comprising a first metal having a first metal electrode potential (FMEP) and the second metal site comprising a second metal having a second metal electrode potential (SMEP), which FMEP being lower than SMEP and SMEP being substantially different such that the implantable device is galvanized when it is deployed. Methods of making and using the implantabe device are also disclosed.
