Hepatic molecular conversion and detoxification of ferritin iron in adult lampreys (Geotria australis), following natural and induced iron loading [PDF]

, 1995
Weekly intramuscular injections of 3 mg of iron as horse spleen ferritin into adult Geotria australis over 10 weeks, resulted in a progressive increase in that form of iron in the serum.

Synergistic Enhancement of Catalytic Activities in Ligand‐Regulated Carbon Dots‐Ferric Ion Nanozymes via UV‐Enhanced Peroxidase‐Oxidase

Advanced Science, EarlyView.
Three CDs‐Fe nanozymes functionalized with tailor‐made ligands (TPP, HEDP, and DTPA) are synthesized via hydrothermal carbonization and coordination chemistry. A ligand‐regulation strategy for CDs‐Fe nanozymes achieves tunable enzyme‐mimicking activities and a powerful synergistic effect between POD and UV‐induced OXD pathways, paving the way for ...

P081 | EVALUATION OF PTPN11 MUTATION SUBTYPES AND THEIR POTENTIAL IMPACT ON CLINICAL OUTCOMES: A SINGLE-CENTER EXPERIENCE.

Haematologica
Background: PTPN11mutations can be found in 1.5%–12% of AML cases. They have been reported to cluster mainly in the N-terminal Src homology region 2 (N-SH2) and phosphatase (PTP) domains.

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

Advanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Zinc and Copper Levels in Patients with Primary Hypertension and Normotension [PDF]

, 2015
One of the causes of primary hypertension is an exposure to free radicals. The formation of free radicals in the body can be prevented by taking antioxidants. Zinc and copper are cofactors of endogenous antioxidant enzyme superoxide dismutase. This study

Intracellular Reactive Oxygen Species Generation Induced by High‐Frequency Ultrasound in Thickness Vibration Mode

Advanced Science, EarlyView.
Cell‐sized high‐frequency ultrasound using a lithium niobate transducer, previously ignored in reactive oxygen species (ROS) production, generated intracellular ROS at frequencies higher than conventionally used. The intracellular generation of ROS by cell‐sized high‐frequency ultrasound revealed in this study is expected to be applied to innovative ...

Microglial Membranes Wrapped Ultrasmall Medium‐Entropy Ru Single‐Atom Nanozyme: Enhanced Catalysis for Accelerating Inflammation/Redox Microenvironment Regulation in Intracerebral Hemorrhage

Advanced Science, EarlyView.
PtRhIr/Ru SAN@M nanozymes cross the blood–brain barrier and selectively accumulate in hemorrhagic brain regions. By mimicking multiple enzyme activities, they attenuate oxidative stress, modulate microglial polarization toward an anti‐inflammatory phenotype, inhibit ferroptosis, and promote neuronal repair.
