Application of Atomic Force Microscopy for Detection of Influence of Antibiotic Upon the Microbial Cell (on the Model of E.coli and I Generation Cephalosporins)

Authors: Yerokhin P. S., Utkin D. V., Kuznetsov O. S., Konnov N. P., Aspen N. A.

Alteration of E.coli cell wall caused by Cefazolin-AKOS was observed atomic force microscopy (AFM). Using semi-contact and contact modes the damaging effect of the Cefazolin-AKOS antibiotic was shown after a 30 minutes exposure. The assessment of physical parameters of cell allow to get more detailed information on the effect of antibiotics on microorganisms.

Comparison of Methods for Phase Synchronization Diagnostics from Test Data Modeling Nonstationary Signals of Biological Nature

Authors: Borovkova E. I., Karavaev A. S., Ponomarenko V. I., Prohorov M. D.

Three methods of phase synchronization diagnostics from time series are compared by the analysis of test data. These data reproduce the statistics of experimental temporal realizations recorded from the system of human cardiovascular system autonomic control.
