Science and politics have always gone together. This is what happened in our days when Russia's military aggression against Ukraine, which began in 2014, turned into a full-scale military invasion in 2022 and a war of liberation for the independence and freedom of Ukraine. These events dramatically affected not only the fate of millions of citizens but also brought the destruction of fields of science and technology important for the existence of the country.

Prenatal treatment with buspirone in rats with prenatal hypoxia impaired learning ability during the first day of 5-day training. A decrease in the effectiveness of long-term memory in comparison with short-term memory was revealed in two groups of rats: prenatal treatment with buspirone in combination with hypoxia and injection of physiological saline without hypoxia.

Object And Methods: The work was performed on blood samples of 45 professionals radiologists/x-ray technologies and 52 conventionally healthy individuals (control group). The content of malondialdehyde and sulfhydryl groups of proteins and peptides (-SH) in blood plasma was determined; catalase enzyme activity and the ratio of pro-antioxidant processes in hemolysates, the level of superoxide anion-radical (О2-) generation, the total production offree radical compounds (reactive forms of oxygen and nitrogen) and the level of apoptosis of peripheral blood lymphocytes (PBL).
The present work continues our recent series of articles that aim to elucidate the ligand-receptor binding mechanism of short cationic peptides to the Na1.8 channel in the nociceptive neuron. The applied methodological approach has involved several methods: the patch-clamp experimental evaluation of the effective charge of the Na1.
