The Study Objective: Was to assess the qualitative and quantitative characteristics of the bone regenerate in the distant period following compression-distraction osteosynthesis.
Material And Methods: Results from the treatment of 30 patients with mandibular micrognathia, were analyzed. Compression-distraction osteosynthesis (CDO) was performed in the area of the mandibular angle.
Purpose: To study the effect of magnetic therapy on the formation of distraction regenerate of the lower jaw in patients with lower micrognathia.
Materials And Methods: The study comprised 159 patients with inferior micrognathia of congenital and acquired etiology. The patients were divided into 2 groups.
American bison demonstrated differential patterns of extinction, survival, and expansion since the terminal Pleistocene. We determined population dynamics of the Northern Great Plains bison using 40 mitochondrial genomes from radiocarbon dated remains with the age ranging from 12,226 to 167 calibrated years before present. Population dynamics correlated with environmental and anthropogenic factors and was characterized by three primary periods: terminal Pleistocene population growth starting 14,000 years ago, mid Holocene demographic stability between 6700 and 2700 years ago, and late Holocene population decline in the last 2700 years.

At the actual stage of becoming of Russian stomatology, the problem of sustainable development of rural stomatological care, as system of local formations of complex medical social nature belongs to national priorities and is considered as one of most important directions of public social policy. The stomatological health of rural population is to be considered as indicator of national stomatological health. This is confirmed by spatial structure: rural territories (inhabited territories outside cities) cover 2/3 of territory of the Russian Federation with population of 37.

To identify best practices for bison stewardship against this backdrop, managers must understand the genetic composition of existing conservation herds. This study characterized 14 plains bison (Bison bison bison) herds managed by the U.
