Mummy of a juvenile sabre-toothed cat Homotherium latidens from the Upper Pleistocene of Siberia.

The frozen mummy of the large felid cub was found in the Upper Pleistocene permafrost on the Badyarikha River (Indigirka River basin) in the northeast of Yakutia, Russia. The study of the specimen appearance showed its significant differences from a modern lion cub of similar age (three weeks) in the unusual shape of the muzzle with a large mouth opening and small ears, the very massive neck region, the elongated forelimbs, and the dark coat color. Tomographic analysis of the mummy skull revealed the features characteristic of Machairodontinae and of the genus Homotherium.

Etruscan Wolf Canis etruscus (Canidae, Carnivora) from the Early Pleistocene of Crimea (Taurida Cave).

The cranial and mandibular fragments of the medium-sized canid from the Early Pleistocene locality of Taurida cave (about 1.8-1.5 Ma) in Crimea are described and included in the hypodigm of the species Canis etruscus Forsyth Major, 1877, a common member of the Late Villafranchian fauna of the Circum-Mediterranean region.

Registry of Acute Myocardial Infarction. REGION-MI - Russian Registry of Acute Myocardial Infarction.

Aim      To study features of diagnosis and treatment of acute myocardial infarction (AMI) in Russian hospitals, results of the treatment, and early and late outcomes (6 and 12 months after AMI diagnosis); to evaluate the consistence of the treatment with clinical guidelines; and to evaluate patients' compliance with the treatment.Material and methods  The program was designed for 3 years, including 24 months for recruitment of patients to the study. The study will include 10, 000 patients hospitalized with a confirmed diagnosis (I21 according to ICD-10) of ST segment elevation acute myocardial infarction (MI) (STEMI) or non-ST segment elevation MI (NSTEMI) based on criteria of the European Society of Cardiology Guidelines on Forth Universal Definition of Myocardial Infarction (2018).

The Taurida Cave, a New Locality of Early Pleistocene Vertebrates in Crimea.

We describe a vertebrate assemblage from the Pleistocene deposits of the Taurida karst cave discovered in 2018 in central Crimea (Zuya village, Belogorsk raion). The assemblage is correlated with Late Villafranchian faunas of the Eastern Mediterranean and has an approximate age of 1.8-1.

A Mass Burial of Fossil Lions (Carnivora, Felidae, Panthera (Leo) ex gr. fossilis-spelaea) from Eurasia.

The vertebrate fauna from the cave deposits in Imanai Cave in the Southern Urals (53°02' N, 56°26'E) has been studied. It contains 715 bones that belonged to at least 11 individuals of fossil lion (Panthera (Leo) ex gr. fossilis-spelaea).
