The article considers the question of the appropriateness of the use of the drug based on succinic acid in the surgical treatment of atherosclerotic occlusion of the carotid artery, for the prevention of neurological complications in the postoperative period. A comparative characteristic of the obtained data of oxidative, antioxidant statuses, as well as markers of neuronal damage in two groups was carried out. The results suggest that the use of cytoflavin during the stages of surgical treatment reduces the number of neurological disorders.

The blood serum of tumor patients contains antibodies recognizing tumor-associated antigens and other molecular products of tumor growth. We studied the interaction of blood antibodies from breast cancer patients with synthetic peptides that were applied on the microchip surface. The serum from healthy volunteers and breast cancer patients was shown to contain antibodies that interact with various peptides. Statistically significant between-group differences were observed in the level of binding with 122 informative peptides (0.01% of the total number of peptides on a microchip). Analysis of antibodies that interact with the peptide panel holds much promise for the diagnostics of breast cancer.
