The flea fauna of mammals in the area between the Kuban and Great Laba Rivers contributes 47 species. The majority of mammal fleas parasitize on several hosts. Peculiarities of the species composition and the structure of flea communities dwelling in different altitudinal belts is estimated. The flea Ctenophthalmus wagneri and some other flea species possessing ancient Mediterranean range show the highest dominance indices in foothills. Ctenophthalmus proximus and Leptopsylla taschenbergi, possessing ranges of the Caucasian type, prevail in the middle mountain belt. Megabothris turbidus and some other boreal species dominate among species collected in the high mountain belt.

Eastern Finnic populations, including Karelians, Veps, Votes, Ingrians, and Ingrian Finns, are a significant component of the history of Finnic populations, which have developed over ~3 kya. Yet, these groups remain understudied from a genetic point of view. In this work, we explore the gene pools of Karelians (Northern, Tver, Ludic, and Livvi), Veps, Ingrians, Votes, and Ingrian Finns using Y-chromosome markers (N = 357) and genome-wide autosomes (N = 67) and in comparison with selected Russians populations of the area (N = 763).

Thin-film membranes of Pd-Ag and Pd-Cu alloys capable of releasing hydrogen in a wide temperature range have been developed. The surface activation of the membranes with a nanostructured coating made it possible to intensify hydrogen transport through Pd-containing membranes at low temperatures. This effect was achieved by accelerating limiting surface processes by increasing the active area of the membrane.

Aim      To evaluate the role of iron deficiency (ID) identified by various criteria, anemia, and the combination of ID and anemia in determining the severity of the clinical course of chronic heart failure (CHF) in a retrospective analysis of data from 498 patients who participated in the ID-CHF-RF Russian multicenter program.Material and methods  ID was diagnosed by the following three criteria established by the European Society of Cardiology (ESC) and the Russian Society of Cardiology (RSC): 1) ferritin concentration <100 μg/l or ferritin concentration 100-299 μg/l in combination with a decreased transferrin saturation (TS) <20%; 2) ID criteria that showed a high sensitivity and specificity when compared with bone marrow morphology (BMM): TS ≤19.8% or serum iron (SI) ≤13 μmol/l; and 3) a composite index including a ferritin concentration <100 μg/l in combination with TS <20% and SI ≤13 μmol/l.

Ratio of AT and GC Pairs in the Zones of Open States Genesis in DNA Molecules.

Front Biosci (Landmark Ed)

November 2024

Department of Biologically Active Substances, Kuban State University, 350040 Krasnodar, Russia.

Background: There is an assumption about the presence of a specific nucleotides sequence in DNA molecule, which contributes to the genesis of open states (OS). In addition, it would be logical to assume that OS zones should form in DNA regions with a large proportion of Adenine-Thymine (AT) pairs, since they contain fewer hydrogen bonds than Guanine- Cytosine (GC) base pairs. However, studies have shown that in areas rich in AT pairs, the probability of open states will not always be higher.
