Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

Advanced Materials, Volume 38, Issue 58, 16 October 2026.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Associations of plasma HDL subclasses with incident dementia risk in older adults

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Plasma high‐density lipoprotein (HDL) varies in size. We examined the associations between HDL subclasses and their lipid composition and incident dementia risk in older adults. METHODS We included 23,790 United Kingdom (UK) Biobank (UKB) and 147 Atherosclerosis Risk in Communities (ARIC) older adults free of dementia at baseline.

From Tradition to Bioactivity: Chemical and Biological Evaluation of a Reformulated Algerian Ancestral Soap Enriched With Lavandula dentata L. Essential Oil

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Effects of thyroxine and nano‐melatonin supplementation on cryopreserved Simmental bull semen were evaluated. The combination of thyroxine (0.5 µg/dL) and nano‐melatonin (30 µg/dL) significantly improved post‐thaw sperm motility, membrane integrity, antioxidant status, and fertility while reducing oxidative stress and apoptosis.
