Dr. Manjil Hazarika, the professor of Cotton College, Guwahati, visited us for Dec 3 to 13, 2017, as the invitee of prominent foreign scholar program by Seoul National University, South Korea.

He got his PhD degree from Universität Bern, Switzerland, and currently working as Assistant Professor and Head (i/c), in Department of Archaeology, Cotton University, Guwahati, Assam, INDIA (Since November, 2015).

Please see below his great publication in Oxford University Press, about Northeast India-.

[Article] Torus mandibularis in skeletal remains from the Joseon Dynasty and modern Korea

Image
Our paper of "Torus mandibularis in skeletal remains from the Joseon Dynasty and modern Korea" is published in Anthropological Science-.

Torus mandibularis (TM), or mandibular tori, are nodular, excessive bony growths along the lingual side of the lower jaw. TM occurs in varying frequencies in different populations with a higher prevalence in Asiatic and circumpolar groups. The tori are associated with mechanical stress from masticatory and paramasticatory behaviors, heredity, sex, age, and environmental factors. We investigated the presence, location, symmetry, and degree of TM frequencies in two skeletal populations with cultural, biological, and geographical affinities: 15th–18th-century Joseon Dynasty Koreans (n = 119) and 20th–21st-century modern Koreans (n = 77). TM frequency is significantly higher among modern Koreans (54.6%) than Joseon Dynasty individuals (13.3%) for females and males. There are no sex differences in TM prevalence in the archaeological and modern …

[Article] Ancient Ascaris DNA Sequences of Cytochrome B, Cytochrome C Oxidase Subunit 1, NADH Dehydrogenase Subunit 1, and Internal Transcribed Spacer 1 Genes from Korean Joseon Mummy Feces

Our paper, "Ancient Ascaris DNA Sequences of Cytochrome B, Cytochrome C Oxidase Subunit 1, NADH Dehydrogenase Subunit 1, and Internal Transcribed Spacer 1 Genes from Korean Joseon Mummy Feces" is newly published in Journal of Parasitology.

We analyzed Ascaris ancient DNA of cytochrome b, cytochrome c oxidase subunit 1, NADH dehydrogenase subunit 1, and internal transcribed spacer 1 genes extracted from the feces or precipitates of 15- to 18th-century Korean mummies. After multiple Ascaris genes in ancient samples were successfully amplified by polymerase chain reaction (PCR), consensus sequences could be determined by the alignment of the sequences of cloned PCR products. The obtained sequences of each gene were highly similar to those of Ascaris spp. reported thus far but were genetically distinct from Baylisascaris, Parascaris, and Toxascaris spp. The current report establishes that the genetic characteristics of the Ascaris spp. infecting pre-modern Korean societies were…
