Synergistic Sunlight‐Activated Photodynamic and Near‐Infrared‐Induced Mild Photothermal Therapy for Infected Wound Healing Using Functionalized Nano‐Bi2WO6 Composites

Advanced Science, EarlyView.
This work proposes a multifunctional Bi2WO6:Yb,Er@CuS@CS nanocomposite that integrates photodynamic therapy (PDT), near‐infrared‐triggered photothermal therapy (PTT), and Cu2+ release for infected wound repair. The nanocomposite demonstrates enhanced antibacterial efficacy via combined PDT, PTT, and Cu2+ release, effective immunomodulatory by mild ...

Nanozymes for Advanced Hemoglobin‐Based Oxygen Carriers: Applications in Blood Substitution, Wound Healing, Antitumor Therapy, and Beyond

Advanced Science, EarlyView.
This review explores how hemoglobin‐based oxygen carriers (HBOCs) combined with nanozymes create multifunctional materials that deliver oxygen while maintaining redox homeostasis. Beyond artificial blood substitutes, these constructs enable wound healing with light‐triggered oxygen release, cancer therapy through enhanced oxygenation and reactive ...

Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

Advanced Science, EarlyView.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

2129. When Is Methicillin-resistant Staphylococcus aureus not Methicillin-resistant Staphylococcus aureus? [PDF]

Open Forum Infectious Diseases, 2019
Abstract Background As part of active surveillance in our NICU for methicillin-resistant Staphylococcus aureus (MRSA), two isolates representing modified S. aureus (MODSA), which are Methicillin resistant but lacking mecA or C were identified. Our current microbiology laboratory workflow for screening

Dual‐Mode Type I/II Photosensitization of a Stable Mesoporous Hydrogen‐Bonded Organic Framework for Antibacterial Therapy

Advanced Science, EarlyView.
A π‐conjugated donor–acceptor PDI monomer undergoes hydrogen‐bonded self‐assembly to form a robust mesoporous framework. The ordered molecular arrangement promotes efficient intersystem crossing and charge separation, leading to simultaneous Type I and Type II reactive oxygen species generation with a high singlet oxygen quantum yield.

Extensive horizontal gene transfer during Staphylococcus aureus co-colonization in vivo. [PDF]

, 2014
Staphylococcus aureus is a commensal and major pathogen of humans and animals. Comparative genomics of S. aureus populations suggests that colonization of different host species is associated with carriage of mobile genetic elements (MGE), particularly ...

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs
