In a series of 62 patients with variable forms of epileptic attacks the electrochemiluminescent (ECL) parameters of free radical oxidation (FRO) and antioxidant activity (AOA), the content of malonic dialdehyde (MDA) and free fatty acids (FFA) in the blood and cerebrospinal fluid (CSF) were collated with clinico-electroencephalographic characteristics of the disease. The CSF of all patients showed intensified FRO and inhibited AOA which significantly prevailed in cases of uncontrolled paroxysms; for all cases a progressive course of the disease with the development of encephalopathy and psychopathologic syndromes was characteristic, as well as generalized and frequent attacks, the presence of extraparoxysmal epileptic patterns on the ECG and the postparoxysmal syndrome. The spectrum of FRO and AOA parameters in patients with "forced normalization" and signs of drug poisoning are similar to quantitative characteristics of FRO and AOA in cases of frequent attacks and EEG characteristics of the paroxysmal type. The results of the study allow the conclusion that FRO and the electrochemical substrate of epileptization are two parallel closely related processes.

Hydrogen atom transfer (HAT) reactions and their kinetic barriers Δ are important in organic and inorganic chemistry. This study examines factors that influence Δ, reporting the kinetics and thermodynamics of HAT from various ruthenium bis(acetylacetonate) pyridine-imidazole complexes to nitroxyl radicals. Across these 36 reactions, the Δ and Δ can be independently varied, with different sets of Ru complexes primarily tuning either their ps or their °s.

Context: The rotating arc plasma technique for the synthesis of nitrogen-doped graphene capitalizes on the distinctive attributes of plasma, presenting a straightforward, efficient, and catalyst-free strategy for the production of nitrogen-doped graphene. However, experimental outcomes generally fail to elucidate the atomic-level mechanism behind this process. Our research utilizes molecular dynamics simulations to explore theoretically the formation of radicals during the plasma-driven reaction between methane (CH₄) and nitrogen (N₂).

Conventional dual-signal electrochemiluminescence (ECL) sensors feature high sensitivity and reliability, but the involvement of coreactants inevitably results in a complex configuration and shows reproducibility risk. Here, we propose an exogenous coreactant-free dual-signal platform, comprising luminol (anodic luminophore), CdSe quantum dots (cathodic luminophore), and CoO/TiC electrocatalyst (coreaction promoter). At different redox potentials, CoO/TiC induces water oxidation and oxygen reduction to produce OH and O radicals, which subsequently drive cathodic and anodic ECL emission, respectively.

Biodosimetry is crucial for assessing ionizing radiation exposure to guide medical responses. Electron spin resonance (ESR) spectroscopy using fingernails can be effectively used for both occupational and public dose assessments in radiological accidents because of their accessibility and ability to retain stable radiation-induced free radicals. However, despite two decades of research, challenges remain in achieving accurate fingernail dosimetry, mainly owing to the variation in ESR signals among individuals.

Objectives: This study aimed to evaluate the safety and long-term outcomes of a one-stage resection and anastomosis approach without preoperative decompression in patients with left-sided incomplete obstructive colorectal cancer.
Methods: We conducted a retrospective analysis of 571 patients diagnosed with pT3-4NanyM0 left-sided colorectal cancer who underwent radical resection and primary anastomosis without preoperative decompression or a diverting stoma from April 2012 to December 2019. Of these, 97 (17%) patients presented with incomplete obstruction, while 474 (83%) had no obstruction.
