NADPH Oxidase Inhibition Promotes Brain Resilience by Attenuating Tauopathy and Neuroinflammation in Alzheimer's Disease

Advanced Science, EarlyView.
CRB‐2131, as a novel Nox inhibitor, suppresses brain oxidation, tauopathy, and neuro‐inflammation, thereby preventing death of mature neurons and promoting regeneration of immature neurons. Ultimately, this fosters a resilient brain and protects cognition.

Synthesis, In Silico, and Biological Evaluation of Non‐Hydroxamate Benzoic Acid–Based Derivatives as Potential Histone Deacetylase Inhibitors (HDACi)

Chemistry &Biodiversity, EarlyView.
Compound A3bn exhibited strong binding affinities for HDAC2, HDAC6, and HDAC8. A3bn’s anticancer IC50 values were similar to those of SAHA. Cell death resulted from the extrinsic apoptotic pathway. Compound A3bn, a hydrophilic linker, which promotes zinc coordination, may be the cause of its increased activity across HDAC isoforms. ABSTRACT Unregulated

Recovery of Liquid Organic Radioactive Waste Absorbed Into Soil by Extraction

CleanMat, EarlyView.
Radioactive organic liquid waste adsorbed in soil containing pure beta‐emitting radionuclides such as H‐3 must be radiologically characterized for subsequent management. For this purpose, a method for the recovery of radioactive scintillation liquids adsorbed in soil has been developed that simulates this type of waste.
