[The ecological determinancy of development of bronchial asthma in adult population (as exemplified by the Republic of the North Ossetia-Alania].

The intensive impact of anthropogenic factors on health causes more than 40% of all human diseases. First of all, it has to do with respiratory organs and comes out as the main determinant of development of chronic respiratory pathology. The article presents an assessment of negative impact of environmental factors on dynamics of increasing of incidence of bronchial asthma morbidity in the Republic of North Ossetia-Alania.

Ancient DNA of narrow-headed vole reveal common features of the Late Pleistocene population dynamics in cold-adapted small mammals.

The narrow-headed vole, collared lemming and common vole were the most abundant small mammal species across the Eurasian Late Pleistocene steppe-tundra environment. Previous ancient DNA studies of the collared lemming and common vole have revealed dynamic population histories shaped by climatic fluctuations. To investigate the extent to which species with similar adaptations share common evolutionary histories, we generated a dataset comprised the mitochondrial genomes of 139 ancient and 6 modern narrow-headed voles from several sites across Europe and northwestern Asia covering approximately the last 100 thousand years (kyr).

Fossil Asiatic Brush-Tailed Porcupine Atherurus macrourus (Hystricidae, Rodentia) from Northern Vietnam (Bud Cave, Pleistocene-Holocene Transition).

The lower jaw and dental remains of the brush-tailed porcupine are described from the Pleistocene-Holocene boundary deposits of the Bud cave in northern Vietnam. In terms of the average length of the cheek teeth, this porcupine is somewhat larger than the modern Atherurus macrourus (Linnaeus, 1758), but slightly smaller than the Pleistocene A. karnuliensis Lydekker, 1886; relatively small incisors make it possible to assign the form from the Bud сave to A.

Pleistocene Mammals from the Lang Trang Cave (Vietnam): New Data.

The following mammal assemblage was identified among the materials collected in 2020 from the Pleistocene of the Lang Trang cave (northern Vietnam): the primates Pongo sp., Trachypithecus sp., Macaca cf.

A Finding of a Frozen Mummy of a Lemming (Rodentia, Cricetidae, Lemmus) in the Upper Pleistocene of Yakutia.

The external morphological, X-ray, and tomographic study of a frozen rodent mummy from the Upper Pleistocene Yedoma deposits on the Tirekhtyakh River (a Semyuelyakh River tributary, Abyi ulus, Republic of Sakha (Yakutia), Russia) showed its belonging to Lemmus sp. The radiocarbon age of the finding is 41 305-41 885 cal B.P.

[DETERMINATION OF PHYLOGENETIC RELATIONSHIP OF YERSINIA PESTIS STRAINS FROM NATURAL PLAGUE FOCI OF THE CAUCASUS BY MULTI-LO- CUS VNTR-ANALYSIS].

Aim: Determination of the degree of phylogenetic relationship of Yersinia pestis strains iso- lated from the territories of natural foci of plague from the Caucasus using VNTR-typing by 25 loci (MLVA25).

Materials And Methods: 26 strains of Y pestis from Russian natural foci of the Caucasus were used in the study. 25 loci of tandem repeats in Y pestis genome by Le Fleche scheme were used for execution of multi-locus VNTR-analysis.

New data on the internal organs of a frozen Yukagir bison mummy (Bison priscus Bojanus, 1827), Yakutia, Russia.

The paper presents the first morphological description of the internal organs of a frozen corpse of the steppe bison Bison priscus (Bojanus, 1827) from the Holocene of northern Yakutia. Necropsy revealed that most of the internal organs, including the brain, heart with the main vessels, and reproductive system were well preserved. It demonstrated that the anatomy of this bison was close to that of the genera Bos and Bison.
