In Russia, during the COVID-19 pandemic, a decrease in influenza circulation was initially observed. Influenza circulation re-emerged with the dominance of new clades of A(H3N2) viruses in 2021-2022 and A(H1N1)pdm09 viruses in 2022-2023. In this study, we aimed to characterize influenza viruses during the 2022-2023 season in Russia, as well as investigate A(H1N1)pdm09 HA-D222G/N polymorphism associated with increased disease severity.

MnO NP were synthesized and studied by electron microscopy. Their antitumor properties were studied in vivo on the model of immunodeficient SCID mice with subcutaneous xenografts of U-87MG human glioblastoma.
