Cerium (Ce) is a hot topic in the field of materials research due to its electronic layer structure and the unique antioxidant abilities of its oxide (CeO ). Cerium oxide nanoparticles (CeO NPs) demonstrate their potential as an antioxidant and antibacterial agent. Current research focuses on whether they can be used to promote wound healing and in what manner. This article provides a systematic review of the various forms of CeO NPs that are used in wound-healing materials over the past decade, as well as the effectiveness demonstrated by in vivo and in vitro experiments, with a focus on the relationship between concentration and effectiveness. CeO NPs are expected to become effective ingredients in dressings that require antibacterial, antioxidant, and wound healing promoting properties. This article serves as a reference for further research and clinical applications of nano-sized CeO in wound healing.

Wound healing is a highly coordinated process driven by intricate molecular signaling and dynamic interactions between diverse cell types. Nod-like receptor pyrin domain-containing protein 3 (NLRP3) has been implicated in the regulation of inflammation and tissue repair; however, its specific role in skin wound healing remains unclear. This study highlights the pivotal role of NLRP3 in effective skin wound healing, as demonstrated by delayed wound closure and altered cellular and molecular responses in NLRP3-deficient (NLRP3) mice.

The challenges associated with prolonged healing or non-healing of chronic diabetic wounds contribute significantly to the increased incidence of lower limb amputation. A pivotal factor in the impediment of healing is the reduced production of endogenous nitric oxide (NO) due to the hyperglycemic microenvironment typical of chronic diabetes. While both endogenous and exogenous NO have been shown to promote the healing process of diabetic wounds, the direct application of NO in wound management is limited due to its gaseous nature and the risk of explosive release.

Background: To analyze the effects of the positioning of a bolt in the femoral neck system (FNS) on the short-term outcomes of middle-aged and young adults with displaced femoral neck fractures (FNFs).
Methods: This was a retrospective study involving 114 middle-aged and young adults with displaced FNFs who were surgically treated with internal fixation via the FNS in the Department of Orthopedics, Suzhou Municipal Hospital, from December 2019 to January 2023. The degree of deviation of the central axis of the femoral head and neck from the tip of the bolt (W), the tip‒apex distance (TAD) and the length of femoral neck shortening (LFNS) were measured on postoperative X-ray and computed tomography (CT) scan images.

Platelet-rich fibrin (PRF) and Enamel Matrix Derivatives (EMD) can support the local regenerative events in periodontal defects. There is reason to suggest that PRF and EMD exert part of their activity by targeting the blood-derived cells accumulating in the early wound healing blastema. However, the impact of PRF and EMD on blood cell response remains to be discovered.

This study verified the efficacy of the Rheocarna, a novel apheresis device, for no-option CLTI or poor-response CLTI after revascularization.
Methods And Results: This multicenter retrospective observational study analyzed 221 patients (221 limbs) with no- or poor-option CLTI (mean [±SD] age 71±10 years; males, 70.
