The method for diagnostics of the phase synchronization of the vegetative control of blood circulation in real time

Background and Objectives: The development of methods for the analysis of non-stationary signals of biological nature makes it possible to solve a number of fundamental and applied problems. The use of these methods is promising for the diagnosis and prevention of diseases of the cardiovascular system. The creation of the device makes it possible to detect diseases at an early stage. However, this requires the development of methods for analyzing non-stationary signals of biological nature in real time.

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)

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.
