The superoxide radical (O.2-) and nitric oxide (NO.) combine very rapidly to form peroxynitrite (ONOO-), a reactive tissue damaging nitrogen species thought to be involved in the pathology of several chronic diseases. The natural product ergothioneine protects against the nitration of tyrosine and the inactivation of alpha 1-antiproteinase by ONOO-. Ergothioneine merits further investigation as a biological and therapeutic antioxidant agent.

Chronic cerebral ischemia (CCI) is one of the most common forms of cerebrovascular disease, which affects a significant number of patients, often leading to disability, cognitive impairment and dementia. The analysis of modern data on the pathogenesis and risk factors for the development of CCI, as well as on the mechanisms of action of Mexidol on various links in the pathogenesis of CCI. A systematic search was conducted in the PubMed, MEDLINE and Google Scholar databases, on Russian and English-language sites with open access publications on the problem of CCI and on the drug Mexidol in the period from 2014 to 2024.

Hypoxic tumors are radioresistant stemming from the fact that oxygen promotes reactive oxygen species (ROS) propagation after water radiolysis and stabilizes irradiation-induced DNA damage. Therefore, an attractive strategy to radiosensitize solid tumors is to increase tumor oxygenation at the time of irradiation, ideally above a partial pressure of 10 mm-Hg at which full radiosensitization can be reached. Historically, the many attempts to increase vascular O delivery have had limited efficacy, but mathematical models predicted that inhibiting cancer cell respiration would be more effective.

Sesamol (SES) and linalool (LIN) are aromatic compounds that have neuroprotective effects. The main purpose of this study is to evaluate the anxiolytic activity of LIN and SES co-treatment on Swiss albino mice and analyze its possible mechanism through in silico study. In this sense, the mice were given the gamma-aminobutyric acid type A receptors (GABA) agonist diazepam (DZP; 3 mg/kg, p.

Background: Mediterranean diet (MD) constitutes a commonly examined dietary model. It includes a plethora of bioactive ingredients with strong antioxidant, anti-inflammatory, antithrombotic and anticancer properties. Several substantial studies support strong evidence that MD can exert preventing actions against human morbidity and mortality, promoting human well-being and quality of life.
