Female‐biased astrocytic priming shapes early locus coeruleus vulnerability in an Aβ oligomer milieu

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The locus coeruleus (LC) is an early site of Alzheimer's disease (AD) pathology, yet the role of brainstem astrocytes in early, sex‐dependent vulnerability remains unclear. METHODS In 2‐ to 3‐month‐old APP/PS1 mice, we combined in vivo proton magnetic resonance spectroscopy (MRS) of the brainstem with region‐resolved molecular ...

Activation of Cyanate Anions by Phosphine Radical Cations Enables Formal Hydrocarbamoylation of Alkenes

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A photocatalytic formal hydrocarbamoylation reaction that employs a cyanate anion as the C1 source and provides N‐acyl iminophosphorane products from activated alkenes is described. Mechanistic investigations suggest generation of a phosphoranyl radical by addition of the cyanate anion to a phosphine radical cation, which enables the delivery of the ...

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.
