Atmospheric Aerosol Neurotoxicity and Parkinson's Disease: Mechanisms and Perspectives

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
Schematic overview of the pathways and pathological mechanisms connecting atmospheric aerosol exposure to PD. Atmospheric aerosols, including PM2.5 and nanometer/ultrafine particles loaded with metal particles, persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and dioxins, enter the body predominantly via pulmonary ...

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

open access: yesJournal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 5, Page 515-524, September 2026.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Nature, origin, and phosphorylation potential of the phosphorus/sulfur‐bearing nanoscale multiphasic assemblages in the CM chondrites Murchison and Murray

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2303-2335, September 2026.
Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

Breaking the Mold: Electrophilic Hydrophosphanation Emerges

open access: yesChemistry – A European Journal, Volume 32, Issue 32, 24 August 2026.
Electrophilic hydride attack on the olefin, instead of the classical nucleophilic addition by a phosphanido ligand, is unveiled in rhodium‐catalyzed olefin hydrophosphanation. This hydride‐driven pathway operates for both activated and inactivated olefins, with transition states characterized by elongated Rh─H bonds and nascent C─H bond formation ...

Dissecting the Electronic Factors Governing Phosphine Oxide Reduction With Silanes: A Computational Study

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 24, 21 August 2026.
Phosphine oxide reduction with silanes is governed by phosphine oxide distortion and silane interaction energies. In R3SiH silanes, NBO analysis reveals that n(O)→σ*(SiR) donation is distributed among several acceptor orbitals, whereas in Ph2RSiH silanes, small electronegative substituents directly bonded to silicon (RCl, OCN, OH) enhance the σ ...
