The shifts in the structure of the prokaryotic community of mountain-grassland soil under the influence of artificial larch plantations.

Creation of artificial forest plantations on a global scale is one of the ways to mitigate the negative effects of climate change on ecosystems, at the same time providing soil protection from erosion, regulation of the hydrological regime and carbon sequestration in soils of different natural and climatic zones. However, the change of the dominant plant community cause significant ecosystem changes, reflecting at the structure and functioning of the soil microbial complex as well. The shifts in prokaryotic community of the meadow soil resulting from the conversion of the native meadow (further grassland) phytocenosis to the artificial forest plantations was investigated with the use of NGS sequencing technology and metabarcoding approach-amplicon sequencing of V4 region of 16 S rRNA (performed on Illumina Miseq platform).

Microbiomes of different ages in Rendzic Leptosols in the Crimean Peninsula.

Rendzic Leptosols are intrazonal soils formed on limestone bedrock. The specialty of these soils is that parent rock material is more influential in shaping soil characteristics than zonal factors such as climate, especially during soil formation. Unlike fast evolving Podzols due to their leaching regime, Leptosols do not undergo rapid development due to the nature of the limestone.

[Predictors of Obstructive Sleep Apnea Syndrome According to Results of Clinical Examintion and Ambulatory Blood Pressure Monitoring].

Objective: to determine the predictors of obstructive sleep apnea syndrome (OSAS) basing on clinical examination, results of night pulse oximetry, daily dynamics of heart rate and blood pressure (BP) in men with newly diagnosed arterial hypertension (AH).

Materials And Methods: Men (n=197, mean age 40.1 ± 8.

Prevalence of human pegivirus-1 and sequence variability of its E2 glycoprotein estimated from screening donors of fetal stem cell-containing material.

Background: Human pegivirus-1 (HPgV-1) is a member of the Flaviviridae family whose genomic organization and mode of cellular entry is similar to that of hepatitis C virus (HCV). The E2 glycoprotein of HPgV-1 is the principle mediator in the virus-cell interaction and as such harbors most of HPgV-1's antigenic determinants. HPgV-1 persists in blood cell precursors which are increasingly used for cell therapy.

[Predictors of Electrical Myocardial Instability in Men With Arterial Hypertension and Obstructive Sleep Apnea-Hypopnea Syndrome].

Objective: To access the detectability of corrected QT interval (QTc) prolongation ( more or equal 450 ms) and increased QT dispersion (QTd more or equal 60 ms) in men with obstructive sleep apnea-hypopnea syndrome (OSAS) and newly diagnosed arterial hypertension (AH).

Material And Methods: We included in this study 138 men (mean age 40.5+/-6.
