Estimation of Decellularization and Recellularization Quality of Tissue-Engineered Constructions by the Chemiluminescence Method.

It was found that the chemiluminescence intensity in native and recellularized tissues of rat muscular organs as well as in their decellularized scaffolds can serve as an express criterion that, along with ultrastructural analysis, makes it possible to perform quantitative assessment of the viability of cellular structures in biological samples of the diaphragm.

Surface bioactivation of PEEK by neutral atom beam technology.

Polyetheretherketone (PEEK) is an alternative to metallic implants and a material of choice in many applications, including orthopedic, spinal, trauma, and dental. While titanium (Ti) and Ti-alloys are widely used in many intraosseous implants due to its biocompatibility and ability to osseointegrate, negatives include stiffness which contributes to shear stress, radio-opacity, and Ti-sensitivity. Many surgeons prefer to use PEEK due to its biocompatibility, similar elasticity to bone, and radiolucency, however, due to its inert properties, it fails to fully integrate with bone.

Multiple increase in productivity of the yeast at reducing the fraction of DO in water.

We found a two-fold increase in the productivity of baker's yeast grown on a nutrient mixture prepared in light water with a DO content (127 ppm) smaller than in the distilled water (150 ppm). The number of water monomers that provides the biosynthetic activity (water transport through membrane channels) of yeast cells with an increased CO yield was determined for the first time. We established that the selectivity of cell membrane channels in water of different composition depends not only on the motion of ortho-and para-spin HO isomers in solution, as was shown earlier, but also on the concentration of DO.

[The metabolic correction of the experimental alloxan diabetes by means of the antioxidant remedies].

The research concerning the effect of the remedies with the different antioxidant mechanisms on the indices of carbohydrate and lipid metabolism as well as the thiol link of the antioxidant system and the functional detoxication system in modeling conditions of the decompensated alloxan diabetes mellitus have been presented. The research was performed on 105 white nonlinear male-rats with initial body weight (b.w.

[Comparative characteristics of the isotopic D/H composition and antioxidant activity of freshly squeezed juices from fruits and vegetables grown in different geographical regions].

Data presented in this paper reflect changes in antioxidant activity, the content of prooxidant factors and deuterium concentration in freshly squeezed juices from fruits and vegetables grown in different climatic regions (10 samples of juices from wholesale and retail trade network of 8 kinds of vegetables and fruits, 28 manufacturers from 14 countries). Determination of the concentration of deuterium was performed using a nuclear magnetic resonance spectrometer. Total antioxidant activity of fresh juices was determined amperometrically after dilution in 2.

[Influence of linseed oil and deiterium depleted water on isotopic D/H composition and functional antioxidant defense of the hepatobiliary system in rabbits with carbon tetrachloride intoxication].

The article presents results of studying the influence of linseed oil and drinking diet with a modified isotopic composition with low deuterium content on indicators of prooxidant-antioxidant system during modeling of liver toxicity. The research was performed on 36 rabbits (weighing 3.1-3.
