Tri‐Layered Bioactive Cutaneous Scaffold with Integrated Bioactive Metal Organic Frameworks to Promote Full‐Thickness Infected Diabetic Wound Healing: Multifaceted Therapeutic Strategies

Advanced Healthcare Materials, EarlyView.
The limitations of existing clinical treatments highlight the need for a more comprehensive strategy for addressing infected diabetic wounds. A tri‐layered scaffold is developed to deliver therapeutics loaded in CuBDC and ZIF‐8 MOFs that are tailored to the requirements of deep‐infected diabetic wounds.

Multiscale Modelling of Lytic Polysaccharide Monooxygenases [PDF]

arXiv, 2016
Lytic polysaccharide monooxygenase (LPMO) enzymes have attracted considerable attention due to their ability to enhance polysaccharide depolymerization, making them interesting in respect to production of biofuel from cellulose. The LPMOs are metalloenzymes that contain a mononuclear copper active site that can active dioxygen. However, many details of

Extracellular superoxide dismutase VdSOD5 is required for virulence in Verticillium dahliae

Journal of Integrative Agriculture, 2021
Plants produce reactive oxygen species (ROS) to defend pathogens. To counteract this attack, certain pathogens express superoxide dismutases (SODs) to scavenge host-derived ROS.

Tumor‐Targeted Exosome‐Based Heavy Atom‐Free Nanosensitizers With Long‐Lived Excited States for Safe and Effective Sono‐Photodynamic Therapy of Solid Tumors

Advanced Healthcare Materials, EarlyView.
Engineered exosome‐based heavy atom‐free nanosensitizers are developed for safe and targeted sono‐photodynamic therapy of solid tumors. The IR820‐TPE‐loaded, biotin‐conjugated exosomes (IR820‐TPE@B‐Exo) demonstrate significant promise for NIR fluorescence imaging‐guided sono‐photodynamic cancer therapy.

Fe(3+)-eta(2)-peroxo species in superoxide reductase from Treponema pallidum. Comparison with Desulfoarculus baarsii [PDF]

Biophysical Chemistry, Elsevier, 2006, pp.38-48, 2015
Superoxide reductases (SORs) are superoxide (O2-)-detoxifying enzymes that catalyse the reduction of O2- into hydrogen peroxide. Three different classes of SOR have been reported on the basis of the presence or not of an additional N-terminal domain. They all share a similar active site, with an unusual non-heme Fe atom coordinated by four equatorial ...

Superoxide and superoxide dismutase in red blood cells.

The St. Luke's Hospital gazette, 1976
In 1969 a previously obscure copper protein of red blood cells, erythrocuprein, was shown to catalyse the dismutation of superoxide radicals. Erythrocuprein thus became superoxide dismutase and the object of intensive study. Superoxide dismutase is typically an enzyme of aerobic organisms which utilize oxygen as the major electron acceptor.
