Several previous studies have demonstrated the benefits of early macrophage 2 activation fat grafts supplemented with macrophage culture. However, this approach is considered impractical in clinical settings because of intraperitoneal induction use. The aim of this study was to investigate the effect of early stromal vascular fraction (SVF) macrophage-2 activation with IL-4 on fat graft survival compared to SVF alone using an animal model for better fat graft viability.

RNA interference (RNAi) and oxidative stress inhibition therapeutic strategies have been extensively utilized in the treatment of osteoarthritis (OA), the most prevalent degenerative joint disease. However, the synergistic effects of these approaches on attenuating OA progression remain largely unexplored. In this study, matrix metalloproteinase-13 siRNA (siMMP-13) was incorporated onto polyethylenimine (PEI)-polyethylene glycol (PEG) modified FeO nanoparticles, forming a nucleic acid nanocarrier termed si-Fe NPs.

Background: Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the use of hyaluronidase to dissolve the fillers. This study aimed to evaluate the efficacy of hyaluronidase in degrading different types of HA fillers and provide clinical guidelines for its use based on filler type, dosage, and application techniques.

BCG remains the only licensed vaccine for tuberculosis (TB), but its efficacy wanes over time. Subunit vaccines, aim to improve BCG immunity and protection, by inducing responses to a few mycobacterial antigens delivered with a specific platform. Since the platform shapes the immune response induced, selecting the right platform has been challenging due to the lack of immune correlates of protection.
