Alleviation of the Genotoxic Effect of Experimental Circulatory Brain Hypoxia in Rat Cornea under the Effect of Infrared Low-Level Laser Radiation.

Experimental modeling of oxidative stress was conducted by creating circulatory brain hypoxia, accompanied by development of free radical processes leading to genome instability through an example of anterior epithelial layer of rat cornea. We studied the influence of infrared low-level laser radiation (ILLLR) in the therapeutic dose and mode (pulse power 8 W, λ=0.89 μm).

Effect of Infrared Low-Intensity Laser Irradiation on Lipid Peroxidation under Conditions of Experimental Circulatory Hypoxia of Visual Analyzer.

The physiological stress modeled by circulatory hypoxia activates LPO processes in various tissues. In posthypoxic period, the infrared low-intensity laser irradiation significantly decreased the chemiluminescence parameters in blood plasma, normalized the retinal levels of diene and triene conjugates, and decreased MDA in the rat brain attesting to the correcting effect of this irradiation during various types of physiological stresses.

Examination of Statistical Instability of Electroencephalograms.

The study examined stochastic stability of EEG samples recorded in succession from the same healthy volunteer at unchanged state. The absence of statistical repetitions not only for EEG samples, but also for the corresponding spectral densities was proven. A method to calculate the pairwise comparison matrices of ECG samples and quasi-attractors was proposed.

New Effect in Physiology of Human Nervous Muscle System.

A new phenomenon (or paradox) consisting in higher statistical stability of samples, for example, tremorograms, in a group of different subjects than in the same subject in unchanged homeostasis. At the same time, it turns out that 15 different subjects are more similar (statistically) to each other than one person to himself in 15 repetitions of tremorogram recording (in unchanged homeostasis). This poses serious problems for physiology and medicine, and in the context of transition to individualized medicine, this raises the question of how different people can be compared if they are statistically more similar than one person to himself.

Combined Effect of Silver Nanoparticles, Ceftriaxone, and Methyluracil during Experimental Purulent Peritonitis.

Bacterial biofilms provoke and/or promote the most chronic and recurrent infectious diseases. Previously, experimental models of purulent peritonitis and meningoencephalitis revealed positive antibiofilm effect of metallic nanoparticles and the absence of resistance against such nanoparticles in microorganisms. This study examines the combined effect of silver nanoparticles with ceftriaxone and methyluracil on recovery mechanisms during inflammatory diseases exemplified by purulent peritonitis in experimental animals.
