Copper-Based Nanozymes: Potential Therapies for Infectious Wounds.

Bacterial infections are a significant obstacle to the healing of acute and chronic wounds, such as diabetic ulcers and burn injuries. Traditional antibiotics are the primary treatment for bacterial infections, but they present issues such as antibiotic resistance, limited efficacy, and potential side effects. This challenge leads to the exploration of nanozymes as alternative therapeutic agents.

Exosomes of different cellular origins: prospects and challenges in the treatment of acute lung injury after burns.

Acute lung injury (ALI) is a critical clinical disease caused by direct factors (inhalation injury, gastroesophageal reflux, ) or indirect factors (including infection, sepsis, burn, shock, trauma, acute pancreatitis, fat embolism, drug overdose, ). ALI is characterized mainly by diffuse interstitial and alveolar edema caused by an uncontrolled inflammatory response and damage to the alveoli-capillary barrier and has very high morbidity and mortality rates. Currently, there is no effective treatment strategy other than mechanical ventilation, fluid management or other supportive treatments.

Silver(I)-iodine cluster with efficient thermally activated delayed fluorescence and suppressed concentration quenching.

Reports on highly efficient silver(I)-based thermally activated delayed fluorescence (TADF) materials are scarce due to challenges in molecular design, although these materials show great potential for photoluminescent and electroluminescent applications. Herein, a silver(I)-iodine cluster, namely AgI(dppb-Ac), is synthesized by employing a donor-acceptor (D-A) type bisphosphine ligand. Due to the introduction of electron-donating iodine ligands, AgI(dppb-Ac) exhibits an emissive singlet state characterized by (metal + iodine)-to-ligand charge transfer and intra-ligand charge transfer transitions, as well as a small singlet-triplet energy gap.

Acute wounds result from damage to the skin barrier, exposing underlying tissues and increasing susceptibility to bacterial and other pathogen infections. Improper wound care increases the risk of exposure and infection, often leading to chronic nonhealing wounds, which cause significant patient suffering. Early wound repair can effectively prevent the development of chronic nonhealing wounds.

Efficient Deep-Blue Organic Light-Emitting Diodes Employing Doublet Sensitization.

Fast and efficient exciton utilization is a crucial solution and highly desirable for achieving high-performance blue organic light-emitting diodes (OLEDs). However, the rate and efficiency of exciton utilization in traditional OLEDs, which employ fully closed-shell materials as emitters, are inevitably limited by spin statistical limitations and transition prohibition. Herein, a new sensitization strategy, namely doublet-sensitized fluorescence (DSF), is proposed to realize high-performance deep-blue electroluminescence.

Nanoarchitectonics of Antibiotic-Releasing Acicular Nanozymes for Targeting and Inducing Cuproptosis-like Death to Eliminate Drug-Resistant Bacteria.

A series of progress has been made in the field of antimicrobial use of nanozymes due to their superior stability and decreased susceptibility to drug resistance. However, catalytically generated reactive oxygen species (ROS) are insufficient for coping with multidrug-resistant organisms (MDROs) in complex wound environments due to their low targeting ability and insufficient catalytic activity. To address this problem, chemically stable copper-gallic acid-vancomycin (CuGA-VAN) nanoneedles were successfully constructed by a simple approach for targeting bacteria; these nanoneedles exhibit OXD-like and GSH-px-like dual enzyme activities to produce ROS and induce bacterial cuproptosis-like death, thereby eliminating MDRO infections.

Safety and efficacy of waterjet debridement vs. conventional debridement in the treatment of extremely severe burns: A retrospective analysis.

Introduction: Patients with extremely severe burns often require rapid wound closure with a tangential excision or escharectomy combined with a skin graft to reduce life-threatening complications such as infection. Traditional tangential excision surgery using the Watson or Humby knife does not allow accurate excision of necrotic tissue and often removes too much active tissue, which is detrimental to the rapid healing of the wound. Importantly, the Versajet hydrosurgical system, with its smaller handle, allows for more precise excision of necrotic burn tissue and preserves more active dermal tissue, positively affecting wound healing and scarring.
