Application of New Instrumental Methods for Evaluation of the Functional State of Cells of Francisella Tularensis in a Stressful Environment

The structure of the cell surface reflects the functional state of the bacterium as a whole. The presence of specific features of cells affects the biophysical characteristics of their surface: charge, free energy and hydrophobicity. The interaction of bacteria with biomolecules and particles is also related to these surface characteristics. The aim of our work was to study the function of F. tularensis 15 NIIEG cells under cultivation under stress using electro-optical (EO) monitoring.

Morphofunctional Changes in Microcirculatory Vessels of Hypertensive Rats’ Cardiac Muscle under Stress

Investigations of disorders of the heart’s structure and functions at the early stages of development, elaboration of prophylactic measures preventing or decreasing the risk of myocardium in- farction with the presence of the hypertension disease continue to remain unconditionally topical up to now. The aim of this ex- perimental work lies in finding out the morphofunctional signs of cardiovascular lesions produced by stress factors with the presence of arterial hypertension.

The Effect of Emotional and Severe Pathological Stresses on the Level of Arterial Pressure and the Production of Testosterone in Female and Male Rats

The serum level of testosterone is indicator of organismcapacity. Chronic stress is accompanied by development of more pronounced arterial hypertension in males compared with females that is associated with the decrease in production of testosterone in males but not in females.
