Chemiluminescent Analysis of Oxidative Metabolism in Rat Blood under the Influence of Argon and Helium.

We studied the nature of the action of course treatment with argon and helium (1 min, 3 procedures) on the oxidative metabolism in rat blood plasma. The study was performed on 30 Wistar rats divided into 3 groups (n=10 in each group): intact and 2 experimental (treatment of the skin of the back with a stream of argon and helium, respectively). After completion of the treatment course, the intensity of free radical processes, the total antioxidant activity, and malondialdehyde concentration were evaluated in the blood plasma.

Some Beneficial Effects of Inert Gases on Blood Oxidative Metabolism: Study.

The aim of the study was to assess the effect of external use of inert gases (helium and argon) on the state of free radical processes in vivo. The experiment was performed on 30 male Wistar stock rats (age-3 months, weight-200-220 g.), randomly distributed into 3 equal groups.

Impact of deforestation and temporal land-use change on soil organic carbon storage, quality, and lability.

Soil organic carbon (SOC) plays a key role in regulating soil quality functions and ecosystem services. The objective of our study was to evaluate the impact of deforestation and subsequent land-use change on the SOC and total nitrogen (TN) concentration, quality, and lability under otherwise similar soil and environmental conditions. Geo-referenced composite soils (0 to 30 cm depth at 7.

Experimental Evaluation of the Effect of Argon Cold Plasma on Oxidative Metabolism of the Blood.

We studied the effect of course exposure to argon cold plasma (ten 1- and 2-min procedures) on some parameters of the oxidative metabolism of rat blood plasma. The intensity of free radical processes, the total antioxidant activity, and malondialdehyde concentration in rat plasma were evaluated. It was found that 2-min exposure to argon cold plasma and nonionized argon stream produce a prooxidant effect, while 1-min exposure argon plasma led to stimulation of the antioxidant reserves of the blood.

Scaffolds Based on Poly(3-Hydroxybutyrate) and Its Copolymers for Bone Tissue Engineering (Review).

Biodegradable and biocompatible polymers are actively used in tissue engineering to manufacture scaffolds. Biomedical properties of polymer scaffolds depend on the physical and chemical characteristics and biodegradation kinetics of the polymer material, 3D microstructure and topography of the scaffold surface, as well as availability of minerals, medicinal agents, and growth factors loaded into the scaffold. However, in addition to the above, the intrinsic biological activity of the polymer and its biodegradation products can also become evident.
