An analysis of mtDNA polymorphism in eight populations of aboriginal residents (N = 519) of the Far East has been performed. The majority of haplogroups revealed in the examined groups were of East Eurasian origin. Haplogroup D was revealed in seven populations and its frequency varied from 2.8% in Koryaks to 28.3 and 28.9% in Nanaians and Evenks, respectively. Chukchi and Koryak populations, which belong to the same language family, exhibited haplogroup G, which has the same motive and indicates the genetic kinship of both populations. The presence of East Eurasian haplogroups A and D with a strong predominance of haplogroup A in Chukchi indicates the closer relationship of this population both with Asian and Canadian Eskimos and northern Atapasks on the other side of Bering Strait. The high level of genetic variability was revealed in populations belonging to the Tungus-Manjur group. The high frequency of east Eurasian haplogroups in Nanaians could result from close historical associations with Siberian Evenks.

Cellulose-based sorbents are promising materials for wastewater treatment due to their environmental friendliness, biodegradability, and high sorption capacity. This paper presents an overview of cellulose modification methods, including carboxylation, amination, oxidation, graphene, and plasma treatments, as well as combined approaches. Their effect on key physicochemical properties, such as porosity, morphology, and chemical stability, is considered.

This study investigates the Y-chromosome genetic diversity of the Turkmen population in Turkmenistan, analyzing 23 Y-STR loci for the first time in a sample of 100 individuals. Combined with comparative data from Turkmen populations in Afghanistan, Iran, Iraq, Russia, and Uzbekistan, this analysis offers insights into the genetic structure and relationships among Turkmen populations across regions across Central Asia and the Near East. High haplotype diversity in the Turkmen of Turkmenistan is shaped by founder effects (lineage expansions) from distinct haplogroups, with haplogroups Q and R1a predominating.

Focusing on the Yashkun population of Gilgit-Baltistan, an administrative territory in northern Pakistan, our study investigated mtDNA haplotypes as indicators of ancient gene flow and genetic diversity. Genomic DNA was extracted and evaluated for quality using agarose gel electrophoresis. The complete control region of mtDNA (nt 16024-576) was amplified via PCR, and sequencing was performed using the Big Dye Terminator Kit on an Applied Biosystems Genetic Analyzer.
