Thermoheliox: effect on the functional hemodynamics of the human brain.

A kinetic study of the effect of thermoheliox (inhalation of a helium and oxygen mixture, 70 °C) on the functional hemodynamics of the human brain by functional magnetic resonance imaging was carried out. The dynamic responses of the BOLD signal were found to be biphasic. An empirical equation describing the first phase of the hemodynamic response to visual stimulus was proposed. It was shown that preliminary inhalation of thermoheliox stimulates the hemodynamic responses by slowing down the vasoconstriction.

Thermovaccination: Thermoheliox as an Immune Response Stimulant. Kinetics of Antibodies and C-Reactive Protein Synthesis in Coronaviral Infection.

The high efficiency of using thermoheliox (inhalation with a high-temperature mixture of helium and oxygen) in the treatment of patients affected by COVID-19 was shown. The dynamics of accumulation of IgG, IgM, and C-reactive protein (CRP) in patients with coronavirus infection in the "working" and control groups was studied experimentally. It was shown that thermoheliox intensifies the synthesis of IgG, IgM, and CRP antibodies, while eliminating the induction period on the kinetic curves of the synthesis of specific antibodies in the IgG form and transfers the synthesis of CRP to a fast phase. The results of experiments confirm the previously obtained data based on the analysis of the kinetic model of the development of coronaviral infection in the human body.

Thermovaccination, thermoheliox as a stimulant of immune response. Kinetic model of process development.

A kinetic model is proposed to describe the key features of development of an acute viral infection, accumulation of antibodies, and immune response in the human body. The general features of immune system stimulation by thermoheliox are described. The model can be used for developing the basis for the application of thermoheliox in the treatment of patients affected by coronavirus.

Kinetic model of development of acute viral infection in the human body. Critical conditions, control mechanisms, "thermoheliox".

A kinetic model of the development of acute viral infection is proposed and the dynamic behavior of key variables, including the concentrations of viral particles, infected cells, and pathogenic microorganisms, is described. The change in the hydrogen ion concentration in the lungs and pH dependence of the activity of carbonic anhydrase, a key respiration enzyme, are critical factors. An acute bifurcation transition determining either the life or collapse of the system is demonstrated. The transition is associated with exponential increase in the concentrations of participants in the process and with functioning of the key enzyme, carbonic anhydrase. A physicochemical interpretation is given for the therapeutic effect of temperature rise and potential therapeutic effect of "thermoheliox", that is, breathing by heated helium-oxygen mixture.

Kinetics of Chemical Processes in the Human Brain. The Cholinergic Synapse-Mechanisms of Functioning and Control Methods.

In the framework of the kinetic model, the functioning of the cholinergic synapse is considered. The results of mathematical modeling of changes in the level of acetylcholine, induced pH impulse, the influence of the frequency of impulse transmission and inhibition of acetylcholinesterase are presented. Physicochemical explanation for a number of important physiological phenomena, such as neuromuscular paralysis, the molecular mechanism of neurological memory, and actions of nerve poisons and toxins, is given.

Kinetics of Chemical Processes in the Human Brain. Proton Blockade of Acetylcholinesterase and pH-Impulse in the Mechanism of Functioning of the Cholinergic Synapse.

A kinetic model describing the dynamics of synaptic "discharge" taking into account the kinetics of the injection of the neurotransmitter into the synaptic cleft, the pH-dependence of the catalytic activity of the enzyme, and diffusion withdrawal of protons is proposed. The model provides a physicochemical explanation for a number of important physiological phenomena, such as the neuromuscular paralysis, the molecular mechanism of neurological memory, and the effect of some neurotoxins and drugs.
