Neuroprotective Effects of Senecio brasiliensis Extract Against Chlorpyrifos‐Induced Neurotoxicity and Oxidative Stress in Drosophila melanogaster

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 139, Issue 3, September 2026.
ABSTRACT Chlorpyrifos (CP) is an organophosphate insecticide that induces neurotoxicity through acetylcholinesterase (AChE) inhibition and redox imbalance, raising environmental and occupational health concerns. Plant‐derived compounds from Senecio brasiliensis, native to the Pampa biome, offer multitarget therapeutic potential.

Lipid Nanoparticle Co‐Delivery of mRNA and a Small Molecule Drug for Oral Cancer Chemoimmunotherapy

open access: yesAdvanced Materials, Volume 38, Issue 47, 21 August 2026.
Co‐encapsulation of p53 mRNA and the small molecule ciclopirox within a lipid nanoparticle yields an all‐in‐one chemoimmunotherapy for oral squamous cell carcinoma. The platform engages caspase‐driven apoptosis in cancer cells while repolarizing tumor‐associated macrophages, achieving tumor reduction in both p53‐susceptible and p53‐resistant models and

Electrochemical Reduction of Nitrate to Ammonia on Transition‐Metal Sputtered Copper Foams

open access: yesChemElectroChem, Volume 13, Issue 15, 1 August 2026.
Thin, sputter‐deposited cobalt layers on copper foam significantly enhance electrochemical reduction of nitrate to ammonia, exhibiting an approximately threefold increase in Faradaic efficiency for ammonia, likely due to a synergistic two‐step conversion pathway involving both copper and cobalt sites.

Metabolite‐Driven Biological Activity of Mandragora autumnalis and Spartium junceum: A Comparative LC‐MS/MS Study on Antioxidant, Cholinesterase, and Carbonic Anhydrase Inhibition

open access: yesChemistryOpen, Volume 15, Issue 8, August 2026.
Low‐molecular‐weight phenolic acids in M. autumnalis were associated with antioxidant activity, AChE, and hCA inhibition effects, whereas flavonoid‐rich S. junceum displayed BChE‐oriented inhibition effect and antibacterial activity. LC‐MS/MS‐based metabolite profiling linked distinct chemical compositions to bioactivity patterns, supporting further ...

PbrIDD2‐PbrAPX14 Module Functions in the Ethylene‐Mediated Ripening and Senescence Process of Pear Fruit

open access: yesPlant Biotechnology Journal, Volume 24, Issue 8, Page 4878-4896, August 2026.
ABSTRACT Endogenous H2O2 participated in the ethylene‐dependent ripening and senescence process of horticultural fruit as a secondary messenger; however, the molecular mechanism beneath such a phenomenon has not been fully clarified until recently. By a conjoint analysis of metabolite, enzyme activities, gene expression profiles in AsA‐GSH cycle of ...
