One-electron oxidation and reduction of glycosaminoglycan chloramides: a kinetic study.

, 2013
Hypochlorous acid and its acid-base counterpart, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, these being significant components of the extracellular matrix (ECM).

Matrix-Assisted Processes in CH₄-Doped Ar Ices Irradiated with an Electron Beam

Methane, 2023
The relaxation processes induced by exposure of the Ar matrices doped with CH4 (0.1–10%) to an electron beam were studied with a focus on the dynamics of radiolysis products—H atoms, H2 molecules, CH radicals, and energy transfer processes.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Simulation of proton radiolysis of H2O and O2 ices with the Nautilus code

Astronomy & Astrophysics
Context. The radiolysis effect of cosmic rays (CRs) plays an important role in the chemistry of molecular clouds. Cosmic rays can dissociate molecules on dust grains, producing reactive suprathermal species and radicals, which facilitate the formation of

Safety, efficacy, pharmacokinetics, and mechanisms of novel 10B‐boronophenylalanine combined with a radio‐frequency quadrupole accelerator in boron neutron capture therapy: A preclinical study in head and neck squamous cell carcinoma

Precision Radiation Oncology, EarlyView.
This study demonstrates that the novel 10B‐BPA‐based BNCT system, combined with an RFQ accelerator, effectively targets head and neck squamous cell carcinoma. It induces tumor regression safely and efficiently by triggering DNA damage and activating the ROS/HIF‐1α/NF‐κB pathway, leading to caspase‐3‐mediated apoptosis.
