[Preconditioning by physical factors: role of active forms of oxygen]
Abstract:
In the review mechanisms of protective action of a hyperthermia, light and low-intensity ultrasonic radiation are considered. These physical factors don't cause oxygen starvation, however promote the increase of organ's tolerance to an ischemia/hypoxia. On materials of original articles the analysis of preconditioning mechanisms cause by high temperatures, low-intensive ultrasonic and laser irradiation was carried out at ischemia. By comparison of processes in tissues at influence by physical factors the general triggers--active forms of oxygen (O2*, H2O2, HO*) were revealed.

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
