The paper describes a case of skin wounds inflicted by automutilation in a young woman with psychic regulation disorder. Repeated local irritation and infection produced a complicated systemic disorder leading to hypochromic anaemia which failed to respond to Fe treatment. The paper discusses the mechanism of this type of anaemia which appears in literature under the heading of anaemia of chronic disease (ACD).

The management of complex burn injuries has evolved significantly, with various surgical techniques developed to improve outcomes. This review examines the evolution of these methods, focusing particularly on mesh grafting and the Meek technique. While mesh grafting is effective, it poses challenges such as limited graft coverage and a high demand for autologous skin.

Nanozymes with specific catalytic activity inhibit inflammation and promote wound healing efficiently and safely. In this work, multifunctional manganese-based nanozymes (MnGA) with antioxidant properties were successfully constructed via a simple coordination reaction in which manganese chloride was used as the manganese source and gallic acid (GA) was used as the ligand solution. MnGA possesses both catalase-like (CAT-like) and superoxide dismutase-like (SOD-like) activities and a reactive nitrogen species (RNS) scavenging capacity, which enables it to efficiently inhibit the inflammatory response.

Objectives: For designing a suitable hydrogel, two crosslinked Alginate/ Carboxymethyl cellulose (Alg/CMC) hydrogel, using calcium chloride (Ca) and glutaraldehyde (GA) as crosslinking agents were synthesized and compared.
Materials And Methods: All samples were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Blood compatibility (BC), Blood clotting index (BCI), weight loss (WL), water absorption (WA), pH, and Electrochemical Impedance Spectroscopy (EIS). Cell viability and cell migration were investigated using the MTT assay and the wound scratch test, respectively.

Phototherapy presents an effective approach for treating localized methicillin-resistant Staphylococcus aureus (MRSA) infections; however, the tradeoff between therapeutic efficacy and negative off-target effect persists. To address these issues, we have developed a nanoparticle-hydrogel superstructure comprising phototherapeutic liposomal nanobubbles (NB) and fat extract (FE) encapsulated by F-127 hydrogel. After local administration to sites of MRSA infection, the superstructure effectively neutralizes high levels of MRSA toxins to protect against toxin-mediated cytotoxicity through loaded, which can also be leveraged to enhance anti-MRSA efficacy via toxin-regulated on-demand phototherapy upon near-infrared irradiation.

Persimmon (Diospyros kaki L.) leaves are a traditional medicinal herb used for treating many infectious and inflammatory-related conditions, including wound healing. To validate its traditional use, our study evaluates the acute toxicity and wound-healing effects of methanolic extracts of Persimmon (Diospyros kaki L.
