The purpose of this study was to compare strength, bulk and time of repair of human cadaveric flexor digitorum profundus tendons repaired in situ versus ex situ. Ninety-six human cadaveric flexor digitorum profundus tendons were transected 5 mm distal to the A2-pulley and randomized to 2-strand, 4-strand or 6-strand repairs. We found no significant differences in repair strength between in situ and ex situ repairs, but repair strength increased with increasing number of strands. The cross-sectional area of the repair was not significantly related to the number of strands, but 4- and 6-strand in situ repairs were bulkier than ex situ repairs. In situ repair took longer, and repair time increased with increasing number of strands. We suggest that cadaveric studies of flexor tendon repair should be performed in situ in order to better mimic the clinical reality of tissue handling and repair bulkiness.

Background: Closed head injury (CHI) provokes a prominent neuroinflammation that may lead to long-term health consequences. Microglia plays pivotal and complex roles in neuroinflammation-mediated neuronal insult and repair following CHI. We previously reported that induced neural stem cells (iNSCs) can block the effects of CXCL12/CXCR4 signaling on NF-κB activation in activated microglia by CXCR4 overexpression.

Background: Neuropilin-1 (NRP1) is a transmembrane protein involved in surface receptor complexes for a variety of extracellular signals. NRP1 expression in human cancers is associated with prominent angiogenesis and advanced progression stage. However, the molecular mechanisms underlying NRP1 activity in the tumor microenvironment remain unclear.

Scientists investigated probiotic-containing dressings to address the challenges associated with burn injuries, namely infection and antimicrobial resistance. The present investigation sought to evaluate the impact of innovative probiotic-loaded microparticles with in situ gelling characteristics on infected burns. The strain, Lactiplantibacillus plantarum, was selected due to its demonstrated wound-healing potential.

Antioxidant hydrogels that can provide a moist environment and scavenge reactive oxygen species have emerged as highly potential wound dressing materials. In situ-forming and good tissue adhesiveness will make them more desirable, as they can fill the irregular wound defect, stick to the wound, and offer intimate contact with the wound. Herein, a hydrogel dressing combining in situ-forming, good tissue adhesiveness, and excellent antioxidant capabilities was developed by simply conjugating dopamine onto carboxymethyl chitosan.
