Biological rhythms: influence on the cardiovascular system performance

Subjects of our experimental studies were neurons in the snail Helix Pomatia, from which continuous intracellular recordings according to our specific microelectrode recording technique were produced.

The proposed editorial article touches upon aspects of fundamental medicine associated with the discovery of systems of nonspecific adaptation reactions in the organism as a whole. It is shown that the key law of the organism's response to the actions of the external and internal environment consists in the dependence between the reaction quality and the quantity (measure, intensity) of an acting factor.

Offered is an overview of the author's papers in exploring an interface between biological rhythms of energy, function and biosynthesis in a nerve cell of a crayfish stretch receptor. Parameters of mitochondrion aggregation rhythms integrally determine the energy metabolism in the cell.

In order to reveal the functional interrelationships of the main physiological characteristics of the organism with the external environment exogenous abiotic factors, as well as the evaluation of the magnetic field factor effect on the morphofunctional status main characteristics, 18 healthy men aged 25–49 years old, residents of the North-East of Russia (Magadan) were examined.

At present, control of properties of biological membranes as targets of magnetic field applications within a living cell is the subject of considerable discussion in the scientific community. Experimental studies carried out by us demonstrate that ULF MF has an access to the most important mechanisms of tumor growth. The most likely mechanism among them is that responsible for the processes of free-radicals oxidation.

Some results obtained in recording and processing of phonocardiograms are presented herein. To process phonocardiographic signals, a cascade filtration method has been used that allows detecting tones of the cardiovascular system in the background noise. The effectiveness of the proposed processing method is demonstrated by the results of visualization.
