To help unravel some of the early Eurasian steppe migration movements, we determined the Y-chromosomal and mitochondrial haplotypes and haplogroups of 26 ancient human specimens from the Krasnoyarsk area dated from between the middle of the second millennium BC. to the fourth century AD. In order to go further in the search of the geographic origin and physical traits of these south Siberian specimens, we also typed phenotype-informative single nucleotide polymorphisms. Our autosomal, Y-chromosomal and mitochondrial DNA analyses reveal that whereas few specimens seem to be related matrilineally or patrilineally, nearly all subjects belong to haplogroup R1a1-M17 which is thought to mark the eastward migration of the early Indo-Europeans. Our results also confirm that at the Bronze and Iron Ages, south Siberia was a region of overwhelmingly predominant European settlement, suggesting an eastward migration of Kurgan people across the Russo-Kazakh steppe. Finally, our data indicate that at the Bronze and Iron Age timeframe, south Siberians were blue (or green)-eyed, fair-skinned and light-haired people and that they might have played a role in the early development of the Tarim Basin civilization. To the best of our knowledge, no equivalent molecular analysis has been undertaken so far.
The aim of this study was to identify the prognostically significant anthropometric and bioimpedance indicators for the birth of a child with a high BW in Yakut women.The study included 220 women of Yakut nationality with physiological pregnancy and childbirth who were examined on the third and fourth days after delivery. The parameters of anthropometry and bioimpedancemetry in parturient women and the anthropometric indices of newborns were investigated. Anthropometric measurements were carried out according to the method of V.V. Bunak. Body composition was assessed based on bioimpedance analysis using the ABC-01 MEDASS device (Medass, Russia). The conducted research revealed that the anthropometric and bioimpedance indices of Yakut women in the postpartum period (3-4 days after delivery) were significantly different from general population indicators. The parameters of body weight and body mass index of the puerperal women were significantly higher, and phase angle and Xc50 -significantly lower. PCA revealed anthropometric and bioimpedance indices predicting a high birth weight. The obtained data in combination with other indicators can be used to predict the birth of a child with a high birth weight in Yakut women.
Особенности одонтометрических параметров у девушек с различными типами лица В. Г. Николаев, Д. О. Шестак, С. Л. Бакшеева, В. П. Ефремова ФГБОУ ВО «Красноярский государственный медицинский университет им. профессора В. Ф. Войно-Ясенецкого» Минздрава России, Красноярск, РоссияИзучение одонтометрических параметров представляется актуальным для разработки и совершенствования новых методов диагностики и прогнозирования стоматологических заболеваний.Цель исследования -провести сравнительную характеристику размеров коронок зубов верхней и нижней челюстей в зависимости от типа лица.Материал и методы. Исследованы одонтометрические и кефалометрические параметры у 192 девушек в возрасте от 17 до 20 лет. Кефалометрическая программа включала определение скулового диаметра и верхней высоты лица с последующим вычислением лицевого индекса. По величине данного индекса устанавливался тип лица. Одонтометрические показатели регистрировались по оттискам верхней и нижней челюстей.Результаты. Были выявлены достоверные различия: широкий тип лица ассоциируется с меньшими мезио-дистальными размерами коронок первых верхних моляров, верхних латеральных резцов и верхних клыков, а также меньшей высотой коронок нижних клыков. При узком типе лица выявлена противоположная закономерность -все вышеперечисленные параметры в данном случае выше, чем у эуренов. Размерные характеристики зубов при среднешироком лице характеризуются промежуточными значениями между крайними типами лица.Выводы. На основании одонтометрических и кефалометрических исследований дана сравнительная характеристика размеров коронок зубов верхней и нижней челюстей в зависимости от типа лица. Выявлено, показатели одонтометрии имеют особенности в зависимости от типа лица. Новые данные, полученные в результате исследования, дополняют и расширяют уже известные сведения об изученных параметрах, как в теоретических, так и в практических аспектах. Ключевые слова: одонтометрия, одонтометрические параметры, антропология, типы лица, эурены, мезены, лептены.
The study includes anthropometry of 172 young male, obtained data on the length and body mass, measured the transverse diameters of the shoulders and pelvis, various body types was identified by the J.M. Tanner sexual dimorphism index (andromorphic, mesomorphic, gynecomorphic). The chemiluminescent and bioluminescent study of saliva and blood was conducted in the examined young male. We studied the indicators of the antioxidant defense system under the influence of stress. The antioxidant status of saliva was determined using the H2O2-luminol-dependent chemiluminescence method. Data on the activity of NAD (P) -dependent dehydrogenases in blood lymphocytes was obtained from a bioluminescent method of research. Young male of andromorphic body type had large overall and transverse body sizes. Indicators of antioxidant protection of saliva and blood in men of adolescence, the body type of the sexual dimorphism index J.M. Tanner was different. The persons of the andromorphic body type differed in terms of chemiluminescence in comparison with the young male of gynecomorphic body type. The results of bioluminescent blood tests suggest a violation of the catabolic and anabolic processes of carbohydrate and fat metabolism in young men of mesomorphic and gynecomorphic body types. Indicators of the system of antioxidant protection of saliva and blood reflect the sexual characteristics of the body of young male and can be used as additional criteria for diagnosing sex inversion and assessing the risk of developing socially attributed diseases.
