Self‐Assembled Nanoclay Gel With Spheroid MSC‐Derived Exosome Mimetics to Integrate Demineralized Bone Matrix and Noggin‐Targeting miRNA for Synergistic Osteogenesis

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
We report a versatile nanoclay gel carrier platform that enhances the osteogenic efficacy of demineralized bone matrix (DBM) by integrating nanoclay‐based self‐assembly with cell‐derived exosome mimetics loaded with noggin‐targeting miR‐200c. This design amplifies BMP signaling, thereby promoting DBM‐mediated osteogenesis and offering a promising ...

Novel Monoclonal Antibody Detects Small Aβ Oligomers More Sensitively Than Lecanemab in Alzheimer's Disease CSF, Serum and Culture Media

Annals of Neurology, Volume 99, Issue 6, Page 1452-1465, June 2026.
Objective Aqueously diffusible oligomers of the amyloid β‐protein (oAβ) are neurotoxic and play a role in neuronal dysfunction in Alzheimer's disease (AD). Accurate quantification of oAβ in brains and biofluids could be valuable for understanding and monitoring AD.

Electronic Smoking Devices Among University Students: Usage Patterns and Chemical Composition of Inhaled Substances

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT This study investigated the prevalence of electronic smoking device (ESD) use and its associated behavioural and chemical risks among university students in Bahia, Brazil. A cross‐sectional survey was conducted with 355 students from public and private institutions through an online questionnaire between April and May 2023. Among participants,

Unraveling the Electron Transfer Mechanism in the Reduction of Bis(µ‐Oxido) Dicopper Complexes

ChemistryEurope, Volume 4, Issue 6, June 2026.
We elucidate the electron transfer mechanism in bis(µ‐oxido) dicopper complexes stabilized by guanidine ligands. Kinetic and spectroscopic analyses reveal two sequential reduction steps without isomerization to µ‐η²:η²‐peroxido species. Marcus and density functional theory studies show ligand‐dependent reorganization energies and a unique two‐spin–four‐
