In the sixties and seventies, human erythrocytes were extensively studied, but the mechanical and chemical stresses commonly exerted on red blood cells continue to attract interest of scien...
Secretory phospholipasesA(2) (sPLA(2)s) form a large family of structurally related enzymes widespread in nature. Herein, we studied the inhibitory effects of sPLA(2)s from Vipera lebetina (VLPLA(2)), Vipera berus berus (VBBPLA(2)), and Naja naja oxiana (NNOPLA(2)) venoms on (i) human platelets, (ii) four different bacterial strains (gram-negative Escherichia coli and Vibrio fischeri; gram-pos...
Venoms of most Russian viper species are poorly characterized. Here, by quantitative chromato-mass-spectrometry, we analyzed protein and peptide compositions of venoms from four Vipera species (V. kaznakovi, V. renardi, V. orlovi and V. nikolskii) inhabiting different regions of Russia. In all these species, the main components were phospholipases A₂, their content ranging from 24% in V. orlovi...
