Objective: To investigate the effects of rhVEGF on autologous free granular fat grafts in rats.
Methods: Forty-eight Sprague-Dawley rats were randomly divided into three groups, sixteen of each. After the autologous free granular fat transplantation, all groups were treated with the plasmid DNA containing cDNA encoding rhVEGF, the blank plasmid DNA and normal saline respectively as the experimental group, the negative group and the saline group. After 3, 7, 15, 30 days, the rats were sacrificed and the grafts were weighted accurately. Histological pathology was evaluated. Micro-vessel count and the expression of vascular endothelial growth factor (VEGF) were examined by immunohistochemical staining.
Results: The weights of the two latter groups were significantly reduced on the 7, 15, 30 day compared with the experimental group. The expression of VEGF and the micro-vessel count in the experimental group were significantly higher than the other two groups during the latter periods.
Conclusion: The cDNA encoding VEGF can induce the expression of VEGF in fat graft, angiogenesis and reduce the free fat graft absorption.

Selective neurectomy (SN) typically leaves cut nerve endings to be either free-floating or buried in facial muscles. Regenerative peripheral nerve interfaces (RPNIs) use autologous skeletal muscle grafts to provide a nonfacial muscle target for reinnervation. To evaluate the effectiveness of RPNI surgery with SN for improving postoperative facial function through botulinum toxin use and facial movement metrics.

CAR-T cell therapy has revolutionized immunotherapy but its allogeneic application, using various strategies, faces significant challenges including graft-versus-host disease and graft rejection. Recent advances using Virus Specific T cells to generate CAR-VST have demonstrated potential for enhanced persistence and antitumor efficacy, positioning CAR-VSTs as a promising alternative to conventional CAR-T cells in an allogeneic setting. This review provides a comprehensive overview of CAR-VST development, emphasizing strategies to mitigate immunogenicity, such as using a specialized TCR, and approaches to improve therapeutic persistence against host immune responses.

Objectives: Studies comparing alternative autologous vein grafts (AAVG) to single-segment great saphenous vein (ssGSV) grafts report mixed results. The status of AAVG as first choice when ssGSV is unavailable is not unequivocal, based on current evidence. Our study compares results between AAVG and ssGSV in lower extremity bypass surgery.

Opioid dependence can occur in 6% to 10% of patients undergoing breast reconstruction. With the expansion of interdisciplinary initiatives to decrease opioid use after surgery, an updated look at the incidence of and risk factors for prolonged opioid dependence after free flap breast reconstruction is essential. We retrospectively identified all cases of free flap breast reconstruction completed at our institution from 2017 to 2020.

Background: Cold agglutinin disease (CAD) or syndrome (CAS) can be particularly challenging when autologous stem cell transplant (ASCT) is needed. Standard peripheral blood stem cell (PBSC) collection and manipulation involve ex vivo blood manipulations at lower than body temperature, predisposing to agglutination during graft collection, handling, processing, and infusion.
Study Design And Methods: We describe the first case of ASCT for relapsing lymphoma in a patient with high-titer CAD requiring anti-complement therapy and chronic transfusion.
