Amoebozoa is a group of single-celled organisms that change their shape during locomotion. However, there is a taxon-specific complex of morphological characters inherent in the moving amoebae, known as locomotive forms. Actin is one of the proteins most important for amoeboid movement that, together with actin-binding proteins, construct the architecture of the cytoskeleton in the amoeboid cells.

The aim of this work is to evaluate the effect of the KE peptide on gene expression and protein synthesis of SIRT1, PARP1, PARP2 during aging of human mesenchymal stem cells (MSC). The KE peptide increased gene expression and synthesis of the SIRT1 protein in «young» MSCs by 6 and 8,2 times, respectively.

Thermal dissociation of benzoic acid melt molecules leads to the formation of benzoate ions and hydrogen ions. The latter can be absorbed by a lithium niobate wafer, with subsequent diffusion of lithium ions in the acid.
